The temperature control system 229 comprises a temperature monitoring system 230 for monitoring the temperature in the protection box 202 in real time and a temperature control system 231 for adjusting the temperature in the protection box 202, the temperature monitoring system 230 is electrically connected with the temperature control system 231 in a communication manner, the temperature monitoring system 230 comprises a plurality of temperature sensors 2301 which are arranged in parallel, and the plurality of temperature sensors 2301 obtain sensing signals after detecting the temperature of different position points in the protection box 202 in real time.

Further, the temperature control system 231 includes a controller 2311 disposed outside the protection box 102 and an electric heating regulator 2312 and an electric heating regulator 2313 disposed in parallel with each other, the controller 2311 being electrically connected with the electric heating regulator 2312 and the electric heating regulator 2313; the controller 2311 is electrically connected to the first motor 240 and the second motor 250. It should be noted that the temperature monitoring system 230 transmits each sensing signal to the controller 2311 in the temperature control system 231, and the controller 2311 receives the sensing signal, performs information processing on the sensing signal, and obtains an electrical signal corresponding to the sensing signal, so as to feed back the electrical signal to the electric heater regulator 2312 or the electric heater regulator 2313.

It is emphasized that the present embodiment preferably controls the temperature within the enclosure 202 to be in the range of 8-28 degrees celsius. Specifically, when the temperature in the protection box 202 is lower than 8 ℃, the controller 2311 outputs a heating instruction electric signal after receiving the sensing signal, and starts a heating function corresponding to the electric heating regulator 2312; when the temperature in the protection box 202 is between 8 and 28 ℃, the size of the electric signal output by the controller 2311 after receiving the sensing signal is zero; when the temperature in the protection box 202 is higher than 28 ℃, the controller 2311 outputs a refrigeration instruction electric signal after receiving the sensing signal, and starts a refrigeration and temperature reduction function corresponding to the electric heating regulator 2313. It can be seen that, by setting the temperature control system 229, the temperature in the protection box 202 can be well controlled within a fixed range, thereby avoiding the occurrence of faults of the water level detection device at a limit temperature, improving the performance stability of the device of the water level detection device, widening the range of the working condition service condition of the water level detection device, and simultaneously prolonging the service life of the water level detection device.

It should be noted that the horizontal movement of the door panel 111 and the up-and-down adjustment movement of the carrier plate 110 provided in this embodiment are electrically driven and controlled. Specifically, push-pull rods 242 for pushing or closing the door panel are arranged on the opposite left and right sides of the door panel 111, a first motor 240 is connected to the two push-pull rods 242 in a transmission manner, and the first motor 240 is electrically connected with the storage battery 104; the first motor 240 may be controlled by the controller 2311 to electrically drive the push-pull rod 242 to move horizontally, so that the door panel 111 is pushed or closed.

Further, a second motor 250 electrically connected with the storage battery is fixedly arranged at the center of the mounting plate 106, and the top of the second motor 250 is a power output end; the bottom of the bearing plate 110 is provided with a movable top rod 252 corresponding to the position of the second motor 250, and the bottom of the movable top rod 252 is in threaded transmission connection with the power output end. It can be seen that the controller 2311 can control and drive the second motor 250, so that the second motor 250 transmits force to the moving rod 252 in a spiral rotation manner, and the bearing plate 110 is driven to move up and down.

It should be noted that, the convex-concave groove protection sealing structure 332 with the anticorrosive coating greatly improves the sealing performance and the anticorrosive performance of the door plate 311, improves the service capacity of the protection box 302 under the complicated water conservancy condition working condition, and further prolongs the service life of the water level detection device.

Further, in this embodiment, the top edge of the protection box 302, which is engaged with the door panel 311, is provided with a shielding plate 333, the shielding plate 333 is correspondingly movably connected along the length direction of the top edge of the protection box 302, and the shielding plate 333 protrudes from the top edge along the width direction. It should be noted that, due to the influence of natural conditions of direct illumination and wind blowing, the shielding plate 333 is provided to perform protection work from the top gap between the protection box 302 and the door plate 311 to the greatest extent possible, so as to create a long-term relatively stable and good service environment for the protection box 302, ensure the normal and excellent performance of the electrical components in the protection box 302, and facilitate further improving the working stability and service cycle of the device.
