RU-2861418-C1 - SELF-CLEANING SYSTEM FOR PERIODIC WATER RENEWAL IN AQUARIUM

Abstract

FIELD: aquarium maintenance. SUBSTANCE: invention relates to means for regularly renewing water in aquariums and can be used in keeping and breeding fish and other animals and plants having an aquatic habitat. The system contains a U-shaped drain pipe connected to a drain hose, and a fill hose connected to a timer. On one side of the drain pipe there is an upper pipe, on the other side there is a lower pipe, and a thin tube with open ends is placed inside along the perimeter. The upper and lower pipes are configured to rotate up to 45° around their horizontal axis and up to 90° around the U-shaped drain pipe. On the upper generatrix of the U-shaped drain pipe, a hole for air to enter the system is made, closed with a plug. A filter screen to prevent clogging of the system or a fitting with the possibility of connecting the fill hose is installed in the filling hole of the upper pipe. The lower pipe is connected to the drain hose with the possibility of connection to the sewer. The fill hose is fixed on one side in the aquarium above the water surface and on the other side connected to a timer with a built-in valve, to which a flexible supply line is connected on the other side with the possibility of connection to a water pipe. A shut-off valve is located in the flexible supply line in front of the timer. EFFECT: regular renewal of water in the aquarium. 1 cl, 4 dwg

Description

The invention relates to means for regularly renewing water in aquariums and can be used in keeping and breeding fish and other animals and plants that have an aquatic habitat. Currently, various systems for continuous and periodic water renewal in aquariums are available. These systems involve draining the water into the sewer and adding new water from a water pipe (https://www.aqa.ru/wiki/%D0%9F%D1%80%D0%BE%D1%82%D0%BE%D0%BA%D0%B0). These systems typically contain various valves, water level sensors, pumps, and automation equipment. These technical devices make the system difficult to operate, expensive, and prone to failure. While these systems are the simplest in design and use, they lack automation elements and have significant drawbacks: an uncontrolled and unjustified influx of tap water negatively impacts the stability of the aquatic environment. An electronic programmable device for changing liquid in an aquarium is known [RU Patent No. 176402, IPC A01K 63/04, published 18.01.2018], including a pump, a housing and a microcontroller, to which a motor driver, a real-time clock, an information input device, an information output device, a power supply unit, a contactless minimum liquid level sensor and a contactless maximum liquid level sensor, a current sensor, which is connected between the pump and the motor driver, are connected to the power supply unit, the motor driver is connected to the pump, and two hoses are connected to the pump, a filter element and fasteners that are fixed to the walls of the aquarium are attached to the free end of one hose, which is installed in the aquarium, and the end of the other hose with the filter element is installed in a container where the liquid is changed. This technical solution has several significant drawbacks: the presence of electronic devices requires backup power sources in case of power outages; failure of the level sensors or controller can result in flooding; non-standard aquariums require software reconfiguration; if the pump fails, the entire system stops functioning; self-cleaning of the system in case of clogging or for preventative purposes is not provided; and the device is complex in design and expensive. The objective of the claimed invention is to create a system for periodically renewing water in an aquarium that is simple in design, easy to install, and trouble-free in operation. The technical result is an expansion of the arsenal of technical means that ensure a balanced and stable equilibrium of the aquatic environment for the healthy life of aquarium inhabitants. The stated problem is solved and the technical result is achieved by a self-cleaning system for periodically updating water in an aquarium, comprising a U-shaped drain pipe connected to a drain hose, and a fill hose connected to a timer, wherein an upper branch pipe is located on one side of the drain pipe, a lower branch pipe is located on the other side, and a thin tube with open ends is placed around the perimeter inside; the upper and lower branches are configured to rotate up to 45° around their horizontal axis and up to 90° around the U-shaped drain pipe; an opening for air intake into the system, closed with a plug, is made on the upper generatrix of the U-shaped drain pipe; a filter mesh to prevent clogging of the system or a nipple with the ability to connect a fill hose is installed in the fill hole of the upper branch pipe; the lower branch pipe is fastened to the drain hose with the ability to connect to the sewerage system; The filling hose is secured to the aquarium above the water surface on one end and connected to a timer with a built-in valve on the other end, which is connected to a flexible hose with the ability to connect to a water pipe; a shut-off valve is located in the flexible hose before the timer. A balanced and stable equilibrium is maintained through periodic water changes, calculated for the specific aquarium volume and the species of inhabitants and plants. Chlorine, the most dangerous element in tap water and potentially harmful to aquarium inhabitants, doesn't have time to accumulate in the water, as it easily evaporates (up to 70%) between water changes (only 1-3% of the total volume is renewed per water change). Tap water contains many essential microelements and a high concentration of dissolved carbon dioxide, which is essential for plant nutrition. The system's simplicity lies in its lack of complex technical equipment and components, its independence from power sources, and the lack of space required for equipment. Water drains by gravity, using a lightweight, compact, and inexpensive U-shaped drain tube with a thin tube inside. Hoses are minimally rated: any material suitable for drinking water can be used. The drain hose diameter should be 2-3 times larger than the fill hose diameter. Ease of installation is ensured by the simple assembly of all system components, without gluing or soldering. There is no cluttering of space due to the
