Water flows out from the water outlet plate to flush the side of the brush plate in the forward direction, which can play the role of flushing sludge. The brush plate will brush it when it moves over, and because the brush plate moves forward in an inclined manner, it will push the brushed sewage to the outside to keep the top of the bent plate type weighing sensor clean, so as to prevent the accumulation of sludge from affecting the weighing accuracy.

The brush plate is driven by the sliding block to move in an inclined manner. At the same vertical position, four rotating brushes will pass in sequence, so that the rotating brush will sweep the gravel to the next rotating brush, and then it will be swept out of the top of the bent plate type weighing sensor to prevent the car from passing over the top of the bent plate type weighing sensor and pressing on the gravel, causing the pressure of the gravel on the top of the bent plate type weighing sensor to be too large, which may damage the bent plate type weighing sensor. Sweeping out the gravel can protect the bent plate type weighing sensor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] 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 the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] For example, see Figure 1-6 The present invention provides a technical solution: a bent plate type weighing sensor, comprising a bent plate type weighing sensor 1, a fixed frame 2 is fixedly connected to the outer wall of the bent plate type weighing sensor 1, a cleaning mechanism 3 is arranged on the back side of the fixed frame 2, and a brush component 4 is fixedly connected to the outer wall of the cleaning mechanism 3; The cleaning mechanism 3 comprises: A sliding guide rod 301, wherein the sliding guide rod 301 is arranged on the back side of the fixed frame 2; A fixed end 313, the fixed end 313 is movably connected to the left side of the sliding guide rod 301; The large torque motor 302 is movably connected to the right side of the sliding guide rod 301. The large torque motor 302 rotates, allowing the sliding guide rod 301 to drive the sliding guide rod 301 to rotate so that the large torque motor 302 drives the brush plate 304 to be retracted.

[0023] The outer wall of the sliding guide rod 301 is movably connected to a sliding block 303, the front of the sliding block 303 is located at the top of the bent plate weighing sensor 1 and is movably connected to a brush plate 304, the front of the sliding block 303 is located at the left and right sides of the brush plate 304 and are fixedly connected to limiting plates 311 respectively, and the end of the brush plate 304 away from the sliding block 303 is fixedly connected to a counterweight block 305.

[0024] A flow control box 306 is fixedly connected to the top of the high-torque motor 302 . A water pump 307 is fixedly connected to the top of the high-torque motor 302 . The water pump 307 is connected to the flow control box 306 through a pipeline. A water receiving pipe 308 is fixedly connected to the outer wall of the water pump 307 .

[0025] The top of the brush plate 304 is located inside the flow control box 306 and is fixedly connected to a flow control core 309. The inner wall of the flow control box 306 is located on the left and right sides of the flow control core 309 and is fixedly connected to elastic guide pillars 310. The two elastic guide pillars 310 are fixedly connected to a flow control plate 312 on one side close to the flow control core 309. The elastic guide pillars 310 can be pressed and contracted, and will reset under their own elastic force when there is no pressure.

[0026] When in use, the bent plate type weighing sensor 1 is fixed on the corresponding road surface through the fixed frame 2, and the sliding guide rod 301 is fixed at the position corresponding to the bent plate type weighing sensor 1 through the fixed end 313 and the large torque motor 302. The large torque motor 302 can be rotated to drive the sliding guide rod 301 to rotate so that the large torque motor 302 can drive the brush plate 304 to be retracted to prevent the work of the bent plate type weighing sensor 1 from being hindered. When there is sludge on the top of the bent plate type weighing sensor 1, the brush plate 304 is located on the top of the bent plate type weighing sensor 1, the water pipe 308 is connected to the water source, and the sliding block 303 and the water pump 307 are started to move back and forth on the top of the sliding guide rod 301. The sliding guide rod 301 will pull one side of the brush plate 304. Because the brush plate 304 itself is easily affected by the resistance in the air, and the large inclined plate 405 has a large inertia, the brush plate 304 will be restricted to an angle by the limiting plate 311 under the action of the counterweight block 305, and then move to one side in an inclined manner, so that the brush plate 304 will press the sliding guide rod 301 on the corresponding side inward through the flow control core 309, and the water will flow from the flow control box 306 through the corresponding pipe into the corresponding water outlet plate 314, and flow out from the water outlet plate 314 to flush the side of the forward direction of the brush plate 304, which can play a role in flushing sludge. The brush plate 304 will brush it when it moves over, and because the brush plate 304 moves in an inclined manner, the brushed sewage will be pushed outward to keep the top of the curved plate weighing sensor 1 clean.

[0027] When the sliding block 303 moves to the end of one side, it will return to brushing, because the left and right of the counterweight block 305 will still allow the brushing plate 304 to be restricted by the limiting plate 311 on the other side, and then move in an inclined state, and when the brushing plate 304 changes direction, it will drive the flow control core 309 to rotate together. The rotation of the flow control core 309 will push the other flow control plate 312, and the flow control plate 312 that is no longer pushed will be reset under the action of the elastic guide column 310, allowing water to flow through the corresponding pipe into the other water outlet plate 314 and out, to flush one side of the moving direction of the brushing plate 304.

[0028] For example 2, please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: The brushing assembly 4 includes a driving motor 401, which is fixedly connected to the inside of the brushing plate 304. The outer wall of the driving motor 401 is fixedly connected with a fan blade 402, and the fan blade 402 is fixedly connected to the outer wall of the output shaft of the driving motor 401. The bottom of the driving motor 401 is fixedly connected with a rotating brush 404, and the rotating brush 404 is fixedly connected to the bottom of the output shaft of the driving motor 401.

[0029] Four driving motors 401 are provided, each of the four driving motors 401 is provided with a corresponding fan blade 402 , and each of the four driving motors 401 is provided with a corresponding rotating brush 404 .

[0030] The outer wall of the rotating brush 404 is located at the bottom of the corresponding small inclined plates 403 and is provided with four small inclined plates 403 . The outer wall of the brush moving plate 304 is fixedly connected with three large inclined plates 405 .

[0031] A control switch 406 is fixedly connected to the inner side of the limiting plate 311 , and a control switch 406 is also provided on the inner side of the other limiting plate 311 . The two control switches 406 control different directions of the driving motor 401 .

[0032] When using, Figure 1As shown, when the high-torque motor 302 moves to the left, the brush plate 304 will move to the right, and the brush plate 304 will press the button on the inner side of the right limiting plate 311, which will cause the driving motor 401 to rotate. The driving motor 401 drives the rotating brush 404 to rotate, and the rotating brush 404 will brush the top of the bending plate type weighing sensor 1 at a faster speed, which can better brush the sludge on the top of the bending plate type weighing sensor 1. The driving motor 401 will drive the fan blade 402 to rotate, because when the brush plate 304 moves to the left, it will generate a downward blowing airflow through the large inclined plate 405 and the moving fan blade 402. At this time, the airflow generated by the rotation of the fan blade 402 is upward, through The small inclined plate 403 will offset the downward airflow to reduce the airflow blowing toward the ground when the brush plate 304 moves to the left. This can prevent the spilled water from being moved by the airflow, so as to make full use of the water to brush the top of the bent plate type weighing sensor 1. When the brush plate 304 moves to the right, the control switch 406 located on the left side of the brush plate 304 is pressed down by the brush plate 304. At this time, the fan blade 402 is driven to generate a downward airflow, which increases the airflow blowing on the top of the bent plate type weighing sensor 1, and can accelerate the evaporation of the water on the top of the bent plate type weighing sensor 1 under the action of the airflow, and blow the water to the outside to dry the top of the bent plate type weighing sensor 1.

[0033] When the left side of the bent plate type weighing sensor 1 box moves, the rotating brush 404 is driven to rotate. This rotation will sweep the sludge and gravel on the left side of the brush plate 304 on the top of the bent plate type weighing sensor 1 to the front. The brush plate 304 is driven to move in an inclined manner by the sliding block 303. At the same vertical position, four rotating brushes 404 will pass in sequence, so that the rotating brush 404 will sweep the gravel to the next rotating brush 404, and then be swept out of the top of the bent plate type weighing sensor 1. This can effectively prevent the existence of gravel on the top of the bent plate type weighing sensor 1. Due to the existence of gravel on the top of the bent plate type weighing sensor 1, when the car passes by the top of the bent plate type weighing sensor 1 and presses the gravel, the pressure at the position of the gravel on the top of the bent plate type weighing sensor 1 will be too large, which may damage the bent plate type weighing sensor 1.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
