Description

Quick dust suppression watering device in coal yard Technical Field The utility model relates to the technical field of coal yards, in particular to a rapid dust suppression and sprinkling device for a coal yard. Background Coal yards refer to sites dedicated to stacking coal, typically located near coal-fired power plants, steel plants, or other industrial facilities requiring large amounts of coal. The primary function of a coal yard is to store coal for loading and transport when needed. Through searching, the open-air coal storage yard spraying dust suppression device disclosed in China patent with the publication number of CN205199195U comprises a base, a control cabinet and a distribution line, wherein a traction device is arranged on the right side of the base, a water tank is arranged on the base, the water tank is connected with a pressurizing pump, and the distribution line for the pressurizing pump is connected with a generator. The spraying dust suppression device for the open-air coal storage yard can be placed on a mobile locomotive, can be manually pushed, can be manually controlled, can be wirelessly and remotely controlled, is convenient to use and simple to operate, can realize sprinkling and dust removal of the coal storage yard, reduces investment cost, and ensures clean production of ports. In the scheme, although sprinkling dust removal of a coal yard can be realized, investment cost is reduced, and clean production of ports is guaranteed, the sprinkling dust suppression device in the patent is difficult to increase sprinkling dust suppression range, has limited sprinkling range, can perform sprinkling on the whole range of the yard only by repeated moving operation even if the sprinkling dust suppression device is placed on a moving locomotive or pushed manually, is complex in operation and has lower dust suppression efficiency, and therefore, the quick sprinkling dust suppression device for the coal yard is provided to solve the problems. Disclosure of utility model The utility model aims to provide a rapid dust suppression and sprinkling device for a coal yard, which aims to solve the problems in the prior art. The quick dust suppression and sprinkling device for the coal yard comprises a water supply system main body and a protective shell, wherein the inner wall of the protective shell is rotationally connected with a plane worm wheel through a positioning shaft, one side of the plane worm wheel is rotationally connected with a force application linkage rod, one end of the force application linkage rod is rotationally connected with a power swing rod, one end of the power swing rod is fixedly connected with the outer circumferential surface of a driving rod, the outer circumferential surface of the driving rod is rotationally connected with the inner wall of the protective shell, one end of the driving rod is fixedly connected with a U-shaped placement frame, the U-shaped placement frame is provided with a mounting column through a locking bolt, and one end of the mounting column is provided with a spray head. Preferably, the spray head is communicated with the water supply system main body through a telescopic hose. Preferably, the top of the water supply system main body is fixedly connected with a protective shell. Preferably, one side of the protective shell is fixedly connected with a direct current motor. Preferably, the output rotating shaft of the direct current motor is fixedly connected with a unidirectional worm.
