[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1:

[0025] A height-adjustable overflow wall. This embodiment is based on the problem that the height of the existing overflow wall cannot be freely adjusted. In order to achieve flexible adjustment, Figure 1-4 As shown, it includes a U-shaped guide rail 3 installed in a positioning groove 2 on the inner wall of the middle part of the rainwater well 1, a first overflow wall panel 4 is fixed to the outer wall of one side of the U-shaped guide rail 3 by bolts, and a second overflow wall panel 5 is slidably inserted into the inner wall of the U-shaped guide rail 3, a symmetrically distributed rectangular mounting plates 8 are welded to the outer wall of the second overflow wall panel 5 away from the first overflow wall panel 4, and a mounting pipe 9 is slidably inserted into the outer wall of the rectangular mounting plate 8, a fixed frame 12 is welded to the end of the mounting pipe 9, and a floating platform 13 is fixed on the fixed frame 12, both ends of the top of the rainwater well 1 are provided with a fixed seat 18, and a servo motor 19 is fixed to the fixed seat 18 by screws, and the output shaft of the servo motor 19 is connected to a winding roller 20 through a coupling;

[0026] By arranging a fixed first overflow wall panel 4 and a movable second overflow wall panel 5 inside the rainwater well 1, flexible adjustment can be achieved, and adaptive adjustment processing can be performed according to different water volume conditions. In addition, the mutual cooperation between the floating platform 13 and the buoyancy airbag 14 can realize automatic height adjustment without frequent manual adjustment, which greatly improves the practicality during use.

[0027] The outer wall of the first overflow wall panel 4 on one side close to the second overflow wall panel 5 is provided with symmetrically distributed limiting grooves 6, and a sealing limiting plate 7 is welded to the bottom outer wall of the second overflow wall panel 5, and the sealing limiting plate 7 forms a sliding fit with the limiting groove 6, and the outer walls of the rectangular mounting plate 8 and the mounting tube 9 are penetrated with threaded holes 10, and the inner walls of the threaded holes 10 are threadedly installed with fixing bolts 11;

[0028] A buoyancy airbag 14 is bonded to the bottom of the floating platform 13 , and an air injection pipe 15 is connected to the inner wall of one side of the buoyancy airbag 14 .

[0029] The buoyancy of the floating platform 13 is smaller than the self-weight of the second overflow wall panel 5, and the sum of the buoyancy of the buoyancy airbag 14 and the floating platform 13 is larger than the self-weight of the second overflow wall panel 5;

[0030] In the process of adjusting the height of the overflow wall, an emergency alternative plan is also adopted. When the automatic buoyancy cannot be adjusted, the servo motors 19 at both ends are used to pull the second overflow wall panel 5 upward, so that the adjustment can be carried out smoothly. In the process of sliding adjustment, the sealing limit plate 7 set can ensure that the sliding adjustment is smoother.

After the assembly is completed, the external water flow enters the rainwater well 1. , rainwater contacts the buoyancy airbag 14 and the floating platform 13, and the buoyancy of the two will drive the second overflow wall panel 5 to move upward, and with the rise of the water level, the second overflow wall panel 5 will also be gradually lifted, and with the cooperation of the indicator sign 16 and the water depth scale 17, the water level depth can be quickly known. When the buoyancy provided by the buoyancy airbag 14 and the floating platform 13 is insufficient to drive the second overflow wall panel 5 to rise, the servo motors 19 on both sides are used to rotate at a uniform speed at the same time, thereby driving the winding roller 20 to rotate, lifting the second overflow wall panel 5 to move upward, and completing flexible adjustment.
