[0002] The conventional weighbridge installation methods are divided into overhead type and sunken type. The sunken weighbridge is stable and safe. At the same time, since the surface of the weighbridge can be made to be on the same plane as the surrounding roads, it can be temporarily used as part of the road to solve the traffic problem in special cases when the site is limited. In the construction site, the sunken method is often more in line with the site requirements. However, there is a drawback in using the sunken type, that is, it is easy to accumulate water, and the weighbridge sensor is prone to malfunction after being soaked in water.
[0003] Therefore, the utility model proposes a sunken weighbridge drainage system. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the defects of the prior art, provide a sunken weighbridge drainage system, and solve the problems that the existing sunken weighbridge is easy to accumulate water and damage the weighbridge sensor.

[0022] The following further describes the utility model with reference to the drawings and specific embodiments.
[0023] Refer toFigure 1 , the present utility model provides a sunken weighbridge drainage system, which solves the problem that the existing sunken weighbridge is prone to water accumulation and damages the weighbridge sensor. By setting a sump and a first drain pipe, the water accumulation in the weighbridge pit can flow into the sump and then into the municipal drainage ditch through the first drain pipe; by setting a water pump and a second drain pipe, the water pump can be started during the flood season to pump the water accumulation in the sump into the municipal drainage ditch through the second drain pipe. By setting a float valve, when the water level in the municipal drainage ditch is higher than the first drain pipe, the float valve rises with the rising water level in the first drain pipe to block the first drain pipe, thereby preventing the backflow of the water accumulation in the municipal drainage ditch into the sump. By setting a water level float switch, the float switch floats on the water surface in the sump. When the water surface height in the sump is close to the height of the pipe between the weighbridge pit, the water pump is started to pump the water accumulation in the sump into the municipal drainage ditch through the second pipe, thereby preventing the backflow of the water accumulation in the sump into the weighbridge pit.
[0024] The following will describe a sunken weighbridge drainage system of the present utility model with reference to the accompanying drawings.
[0025] Refer to Figure 1 , which shows a top view of the sunken weighbridge drainage system of the present utility model. Refer to Figure 2 , which shows a cross-sectional view of the first drain pipe of the sunken weighbridge drainage system of the present utility model when it is opened. The following will describe a sunken weighbridge drainage system of the present utility model with reference to Figure 1 and Figure 2 .
[0026] As Figure 1 and Figure 2 shown, a sunken weighbridge drainage system of the present utility model includes: a sump 2 communicated with a weighbridge pit 1; a first drain pipe 5 connecting the sump 2 with a municipal drainage ditch 7; a water pump 4 arranged in the sump 2, and the water pump 4 is communicated with the municipal drainage ditch 7 through a second drain pipe 6, and the height of the second drain pipe 6 is higher than the height of the first drain pipe 5.
[0027] In a specific embodiment, the sump 2 is communicated with the bottom of the weighbridge pit 1, one end corresponding to the first drain pipe 5 is communicated with one side of the lower end of the sump 2, and the height of the first drain pipe 5 is lower than the height of the connection between the sump 2 and the weighbridge pit 1.
[0028] In a preferred embodiment, the sump 2 and the weighbridge pit 1 are communicated through a pipe.
[0029] In a specific embodiment, a wire 8 is connected to the water pump 4, and the other end of the wire 8 is connected to a power source.
[0030] In a specific embodiment, a float type water level switch 3 is connected to the water pump 4. The float type water level switch 3 floats on the water surface in the catch well 2. After the water level in the catch well 2 reaches a certain height, the float type water level switch 3 turns on the water pump 4. The float type water level switch 3 is a prior art and will not be elaborated here.
[0031] Specifically, when the height of the water level in the catch well 2 is about to reach the pipe between the catch well 2 and the weighbridge pit 1, the float type water level switch 3 starts the water pump 4, so that the water pump 4 discharges the accumulated water into the municipal drainage ditch 7 through the second drain pipe 6, thereby preventing the accumulated water in the catch well 2 from flowing back into the weighbridge pit 1.
[0032] In a specific embodiment, a vertical part is provided at one end of the first drain pipe 5 located in the catch well 2, and an anti-backflow mechanism is provided in the vertical part. By providing the anti-backflow mechanism in the first drain pipe 5, it is possible to prevent the accumulated water in the municipal drainage ditch 7 from flowing back into the catch well 2 through the first drain pipe 5.
[0033] In a specific embodiment, the anti-backflow mechanism includes a float valve 9 and two water stop rings 10. The two water stop rings 10 are fixedly arranged at intervals on the inner wall of the vertical part of the first drain pipe 5. The float valve 9 is located between the two water stop rings 10, and the inner diameters of the two water stop rings 10 are smaller than the diameter of the float valve 9. When the water level in the municipal drainage ditch 7 is higher than the height of the first drain pipe 5, the accumulated water flows back into the first drain pipe 5, and the float valve 9 rises as the water level in the first drain pipe 5 rises, and gradually cooperates with the upper water stop ring 10, thereby blocking the first drain pipe 5 and preventing the accumulated water in the municipal drainage ditch 7 from flowing back into the catch well 2.
[0034] In a specific embodiment, an arc groove is formed on the upper water stop ring 10 to fit the outer surface of the float valve 9. By the arc groove on the water stop ring 10 fitting the outer surface of the float valve 9, the first drain pipe 5 is blocked, thereby achieving the purpose of preventing backflow.
[0035] The following details the usage process of a sunken weighbridge drainage system of the present invention.
[0036] As Figure 2 shown, when there is accumulated water in the weighbridge pit 1, the accumulated water will flow into the catch well 2 through the pipe, and the accumulated water in the catch well 2 will flow into the municipal drainage ditch 7 through the first drain pipe 5.
[0037] As Figure 4As shown, when the flood season comes and the water level in the municipal drainage ditch 7 is higher than that in the first drain pipe 5, the accumulated water in the municipal drainage ditch 7 will flow back into the first drain pipe 5 in reverse. The float valve 9 rises as the water level in the first drain pipe 5 increases and gradually cooperates with the upper water stop ring 10, thereby blocking the first drain pipe 5 to prevent the accumulated water in the municipal drainage ditch 7 from further flowing back into the catch well 2.
[0038] As Figure 5 shown, when the water level in the catch well 2 continuously rises and drives the float water level switch 3 to gradually rise, when the water level line in the catch well 2 approaches the pipe between the catch well 2 and the weighbridge pit 1, the float water level switch 3 starts the water pump 4, and the water pump 4 pumps the accumulated water in the catch well 2 into the municipal drainage ditch 7 through the second drain pipe 6, thereby preventing the accumulated water in the catch well 2 from flowing back into the weighbridge pit 1.
[0039] The above has described the present utility model in detail in combination with the embodiments of the drawings. Those of ordinary skill in the art can make various variations to the present utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation to the present utility model, and the protection scope of the present utility model will be defined by the scope defined in the appended claims.
