However, when the liquid level detection device for water conservancy projects is actually used, the ultrasonic liquid level sensor and the solar energy conversion component are generally stably installed on the riverbed by the mounting component. However, the solar energy conversion component is fixed at an angle for a long time, which not only makes it difficult to fully receive sunlight, but also easily causes dust or dirt to accumulate on the surface of the solar panel, affecting its light reception efficiency, thereby reducing the effect of solar power generation and affecting the device's detection efficiency of the liquid level.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 The liquid level detection device for water conservancy engineering shown comprises:

[0025] A mounting base 1, a battery box 11 is installed on the top of the mounting base 1, a solar panel 12 is hinged on the top of the battery box 11, a bracket 13 is sleeved on the outside of the battery box 11, a liquid level detector 15 is fixed to the bottom end of the bracket 13, and the liquid level detector 15 is used for water level detection, and a signal controller 14 is fixed to the top of the bracket 13; the structures and principles of the signal controller 14, the liquid level detector 15 and the mounting base 1 are all prior arts, and specific reference is made to the comparative document (publication number CN218895818U, and the patent name is a liquid level detection device for water conservancy projects), which will not be repeated here.

[0026] As can be seen from the above, when in use, the mounting base 1 is first fixed on the riverbed according to the actual installation position. At this time, the position of the liquid level detector 15 should be much higher than the river water level, and the solar panel 12 will absorb sunlight. As the solar panel 12 absorbs light energy, it converts solar energy into the battery box 11, and the battery box 11 supplies power to various electrical equipment. Then the liquid level detector 15 performs ultrasonic detection, and then the signal controller 14 transmits the signal to the remote terminal for detecting the river water level.

[0027] refer to Figure 1-Figure 4As shown, the adjustment component 2 is used to drive the battery box barrel 11 and the liquid level detector 15 to rotate along the mounting base 1, and adjust the position of the solar panel 12 together. The adjustment component 2 includes a sleeve box 22 fixed to the top of the mounting base 1 and a connecting sleeve 21 sleeved on the outside of the battery box barrel 11, and the connecting sleeve 21 is rotatably connected to the sleeve box 22. A disassembly component 3 for quickly disassembling it from the sleeve box 22 is provided on the connecting sleeve 21. A rotatable connecting rod 24 is installed in the sleeve box 22. A clamping seat 23 is fixed to the bottom end of the battery box barrel 11, and the clamping seat 23 is plugged and fixed with the connecting rod 24. A power component for driving the connecting rod 24 to rotate is provided in the sleeve box 22, and a cleaning component 4 for cleaning the outside of the solar panel 12 is provided on the outside of the connecting sleeve 21.

[0028] The power assembly includes a worm wheel 25 sleeved on the outside of the connecting rod 24 and a worm 26 rotatably installed in the sleeve box 22, and the worm 26 is meshingly connected with the worm wheel 25. A motor 27 is fixed in the sleeve box 22, and the motor 27 is used to drive the worm 26 to rotate.

[0030] Through the above technical solution:

[0031] When the position of the liquid level detector 15 needs to be changed, the motor 27 drives the worm 26 to rotate, and then the worm 26 engages with the worm wheel 25 to drive the worm wheel 25 to rotate. At this time, the worm wheel 25 rotates to drive the connecting rod 24 to rotate along the sleeve box 22, and the connecting rod 24 rotates to drive the clamping seat 23 to rotate, so that the connecting sleeve 21 rotates along the outside of the sleeve box 22, that is, the battery box tube 11 rotates along the connecting sleeve 21, driving the bracket 13 to rotate, thereby changing the detection position of the liquid level detector 15, and at the same time, the solar panel 12 is driven to rotate during the rotation of the battery box tube 11, so as to realize the position adjustment of the solar panel 12, which is convenient for the solar panel 12 to fully receive sunlight, and then the solar panel 12 rotates and scrapes against the cleaning rod brush 42, and the cleaning rod brush 42 is used to clean the outside of the solar panel 12, thereby reducing the accumulation of dust or dirt on the surface of the solar panel 12, improving the efficiency of the solar panel 12 in receiving light, and enhancing the detection effect of the device on the liquid level.

[0032] Furthermore, the locking assembly includes screw holes 45 provided on the connecting frame 41 and the ear block 43 and a threaded fixing column 44 screwed into the screw hole 45, and one end of the threaded fixing column 44 extends to the outside of the screw hole 45 and is fixed with a rotating disk; based on this, by rotating the rotating disk, the threaded fixing column 44 is driven to screw into the screw hole 45, so that the connection frame 41 and the ear block 43 lose the limit, which is used to replace or clean the cleaning rod brush 42, ensuring that the cleaning rod brush 42 can thoroughly clean the outside of the solar panel 12. At the same time, the screw hole 45 on the ear block 43 and the screw hole 45 on the connecting frame 41 are kept overlapped with each other, so that the ear block 43 and the connecting frame 41 have a positioning installation effect, thereby reducing the installation time.

[0033] In addition, refer to Figure 1-Figure 3 As shown, the disassembly and assembly component 3 includes a through groove 33 opened on the top of the sleeve box 22 and a slider 35 fixed in the connecting sleeve 21, and the slider 35 is slidingly connected to the through groove 33. A guide groove 34 communicating with the inside of the through groove 33 is opened on the outside of the sleeve box 22, and the guide groove 34 and the slider 35 are rotatably connected. A connecting component is provided in the connecting sleeve 21 to stabilize it with the sleeve box 22.

[0034] The connection component includes a limit groove 32 opened at the top of the sleeve box 22 and a limit ring 31 fixed on the inner top wall of the connection sleeve 21, and the limit ring 31 is plugged into the limit groove 32; a clamping column 36 is also fixed at the top of the connection rod 24, and a triangular groove is opened at the bottom end of the clamping seat 23 for inserting the clamping column 36.

[0035] Through the above technical solution:

[0036] The slider 35 is then pulled out of the through groove 33 to allow the connecting sleeve 21 to be quickly disassembled from the sleeve box 22, which facilitates the maintenance or replacement of the power assembly, reduces the time and difficulty of maintenance, improves the flexibility of the equipment, and further improves the efficiency of the liquid level detection device.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
