Description

Adjustable flow monitor probe fixing device for coal mine Technical Field The invention relates to the technical field of flow monitor probe fixing, in particular to an adjustable flow monitor probe fixing device for a coal mine. Background The adjustable flow monitor probe for the coal mine and the fixing device thereof are core components of a flow monitoring system under the coal mine, and the design of the adjustable flow monitor probe is required to be compatible with explosion-proof performance, measurement precision and installation convenience. The ultrasonic probe adopts a time difference method to measure, and calculates the fluid flow velocity by transmitting and receiving ultrasonic pulses. For example, the YHL500 mine intrinsic safety type ultrasonic flowmeter can be externally clamped on the outer wall of a DN15-DN700 pipeline, is not required to be installed by breaking a pipe, and is suitable for mediums such as underground sewage, circulating water and the like. The probe is internally provided with a low-voltage multi-pulse balanced transmitting technology, so that the anti-interference capability is strong, and the measurement accuracy reaches +/-1%. Differential pressure type probe, which is to measure flow based on the front and back differential pressure of throttle device, such as the pressure tap of mine adjustable orifice plate flowmeter. The probe obtains a differential pressure signal through a diameter distance pressure taking method, and is matched with a differential pressure transmitter to calculate the flow, so that the probe is suitable for DN100-DN1000 pipe diameters, and the measuring range is 0.6-32.0MPa. The capacitive probe is suitable for open channel flow monitoring by utilizing the principle that the capacitance value is changed due to liquid level change. The probe takes air and liquid as dielectrics between two polar plates of the capacitor, calculates the liquid level by an electronic method, and deduces the flow. The outer clamp type fixing support is used for an ultrasonic probe and is fixed on the surface of a pipeline by adopting magnetic attraction or bolts. The design of the bracket needs to ensure that the probe is tightly attached to the pipe wall, so that signal attenuation is reduced. For example, a probe fixing frame of YHL500 is suitable for various pipes such as steel, PVC and the like, and the state of a couplant needs to be checked after the probe fixing frame is installed, so that measurement errors caused by drying are avoided. The inserted fixing seat is used for differential pressure type or turbine type probes and is connected with a pipeline through a flange or threads. The seat body needs to have a sealing function to prevent medium leakage. For example, a fixed seat of a mining orifice plate flowmeter is integrated with a pressure taking nozzle and a temperature compensation interface, so that the depth of a probe can be adjusted on line. The special fixing frame for the open channel is used for a capacitive or ultrasonic open channel probe, and the height and the angle of the frame body can be adjusted to adapt to different water tank geometric shapes. A fixture, such as a YHL100 flow monitor, is bolted upstream of the standard sink to ensure that the probe is vertically aligned with the liquid surface. The current fixing device of the adjustable flow monitor probe for the coal mine is in practical application. At present, the device mainly adopts the tripod to carry out fixed mounting, hangs the sensor on the tripod through the ribbon and uses in throwing into water. However, the fixing mode has obvious problems that the sensor is easy to slide down along with the extension of the service time, and meanwhile, the lower part of the sensor is not effectively fixed, so that shaking is easy to occur under the action of water flow, the water inflow depth is inaccurate to monitor, and the accuracy of water inflow observation data is further affected. Disclosure of Invention The invention mainly aims to provide a probe fixing device for an adjustable flow monitor for coal mines, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The utility model provides an adjustable flow monitor probe fixing device for colliery, includes accomodates sleeve, protruding pipe, connection screw and side direction length adjustment pole, protruding pipe is located the both ends of accomodating the sleeve, and the mouth of pipe of protruding pipe is the connection screw to insert side direction length adjustment pole, two side direction length adjustment poles are along with the width adjustment of mining ditch, realize accomodating the support of sleeve; the side wall of the storage sleeve is provided with a lateral observation port, the middle section of the side wall of the storage sleeve is provided with an L-shaped pipeline, two ends of the L-
