[0026] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0027] See also Figure 1-Figure 5 , the utility model provides a water level self-detection device.

[0028] It includes a water collecting tank 100, in which a water level sensor 400 for remotely measuring the water level in the water collecting tank 100 is arranged, and the model of the water level sensor is WRT-136SX. Due to the arrangement of two water level sensors 400, the water levels detected by the two water level sensors 400 are compared. If the detected water level data are consistent, it means that the water level sensor 400 can be used normally. If the water level data detected by the two water level sensors 400 are different, it means that one of the water level sensors 400 is damaged, so that the staff can repair and replace it in time, thereby ensuring that the staff has accurate water level data; a buoy device 300 for placing the water level sensor 400 is arranged in the water collecting tank 100, and a fixing device 500 for fixing the water level sensor 400 is arranged in the buoy device 300, and a lifting device 200 for driving the buoy device 300 to move up and down is arranged at the top of the water collecting tank 100.

[0029] The lifting device 200 includes a support plate 240 fixedly mounted on the top of the water collecting tank 100, and a round hole is opened on the plate body of the support plate 240; a winding drum 210 for rotation is arranged at the left end of the support plate 240, and a support plate 1 220 for assisting the winding drum 210 in rotating is arranged on the left side of the winding drum 210, and the winding drum 210 and the plate body of the support plate 1 220 are movably connected to facilitate the rotation of the winding drum 210; a lifting device 200 is wound on the drum body of the winding drum 210. A pull rope 230 is provided, and the pull rope 230 passes through the body of the support plate 240. A fixing ring 250 is fixedly installed at the bottom end of the pull rope 230 for snapping onto the buoy plate 310. Thus, when the water level sensor 400 needs to be replaced, the pull rope 230 can be wound around the body of the winding drum 210 by driving the winding drum 210, thereby driving the water level sensor 400 in the buoy device 300 to be pulled upward. Thus, the water level sensor 400 can be easily replaced.

[0030] The buoy device 300 includes a buoy plate 310 for clamping the water level sensor 400 , and a fixing frame 320 for connecting with the fixing ring 250 is fixedly installed on the top of the buoy plate 310 .

[0031] A groove 401 is formed on the rod of the water level sensor 400. A limiting ring 402 for being stuck in the buoy device 300 is fixedly mounted on the rod of the water level sensor 400. The limiting ring 402 is located above the groove 401, so that the water level sensor 400 can be inserted into the buoy plate 310. The limiting ring 402 can prevent the water level sensor 400 from penetrating the buoy plate 310.

[0032] The fixing device 500 includes a clamping assembly 520 disposed in the buoy device 300 and used to be stuck in the groove 401 to fix the water level sensor 400 . The buoy device 300 is provided with a driving assembly 510 for driving the clamping assembly 520 to be stuck in the groove 401 .

[0033] The driving assembly 510 includes a threaded rod 512 which is arranged in the buoy plate 310 for rotation, and the front and rear ends of the threaded rod 512 are connected to the plate body of the buoy plate 310 through bearings to facilitate the rotation of the threaded rod 512; and the rod body of the threaded rod 512 is provided with two sections of threads which are symmetrical in front and back, and the thread rotation directions of the two sections of threads are opposite; a handwheel 511 for driving the threaded rod 512 to rotate is fixedly installed at the front end of the threaded rod 512, and a guide rod 513 for assisting the clamping assembly 520 to move forward and backward is provided on the left side of the threaded rod 512.

[0034] The clamping assembly 520 includes a clamping plate 1 521 and a clamping plate 2 522 which are threadedly connected to the clamping plate 1 521 and are used to be clamped in the groove 401, and the movement directions of the clamping plate 1 521 and the clamping plate 2 522 are opposite; and the clamping plate 1 521 and the clamping plate 2 522 respectively perform opposite movements on the two sections of threads on the rod body of the threaded rod 512, so that the clamping plate 1 521 and the clamping plate 2 522 can be clamped in the groove 401 to fix the water level sensor 400 to prevent the water level sensor 400 from shifting; the operation is simple and convenient, thereby facilitating the maintenance and replacement of the water level sensor 400, thereby saving a certain amount of labor.
