Description

Technical Field

[0001] The present invention relates to the technical field of vehicle detection, in particular to an intelligent vehicle overload detection system for road maintenance. Background Art

[0002] The vehicle overload detection system is mainly composed of a license plate recognition subsystem, a voice command subsystem, a static weighing management subsystem of a scale, a video monitoring system, and a data processing and network transmission system. It is mainly used to detect whether the vehicle weight is overweight and affects road safety and life. In the vehicle overload detection system, the main tool for weighing the vehicle is a scale, which is divided into a shallow pit scale and a pitless scale according to the different installation methods. The shallow pit scale is installed underground, and the surface of the scale is flush with the ground after installation; the pitless scale is installed on the ground plane, and the surface of the scale is higher than the ground, and slopes are required on both sides to facilitate getting on and off the vehicle.

[0003] When a shallow pit scale is in use, since it is installed in a previously excavated pit, the surrounding water will flow into the pit, causing serious water accumulation in the pit. At present, the scale is generally able to drain water through the water pumps installed on both sides of it. However, when the rainfall is heavy and the terrain is low, the drainage efficiency of the water pump cannot keep up with the combined water inflow of rainwater falling from the sky and rainwater flowing from the ground to the pit. Moreover, the sludge attached to the ground and the surface of the scale will be driven into the scale by the water flow, causing blockage of the drainage pipes installed around the scale and affecting the drainage effect of the water pump. If the water pump does not drain the accumulated water in time, the sensor element installed in the pump will be soaked, which will be damaged over time, eventually affecting the detection accuracy of the scale and even causing the scale to fail.

[0004] In view of this, in order to overcome the above technical problems, the present invention proposes an intelligent vehicle overload detection system for road maintenance, which solves the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The embodiment of the present invention provides an intelligent vehicle overload detection system for road maintenance, which solves the technical problem that the sludge attached to the surface of the scale in the existing intelligent vehicle overload detection system for road maintenance will be driven into the scale by the water flow, causing blockage of the drainage pipe installed around the scale, affecting the drainage effect of the water pump, and if the water pump fails to drain the accumulated water in time, the sensor element installed in the pump will be soaked, causing damage to the sensor element over time, ultimately affecting the detection accuracy of the scale or even causing the scale to fail.

[0031] The technical solution in the embodiment of the present invention is to solve the above technical problems. The overall idea is as follows: a driving bar and a dredging rod are arranged between the weighbridge and the side wall of the drainage cavity, so that every time the car needs to be weighed and passes through the weighbridge, the driving bar is squeezed to drive the dredging rod to scrape the inner wall of the drainage hole. Compared with the existing method of draining water through a water pump, the technical solution squeezes the driving bar by the way that the car needs to be weighed and passes through the weighbridge, and the driving bar drives the dredging rod to scrape the inner wall of the drainage hole, thereby preventing sludge from clogging the drainage hole and ensuring that the drainage hole is always in a dredged state;

[0032] Embodiment 1:

[0033] like Figure 1 , Figure 2 As shown, the intelligent vehicle overload detection system for road maintenance of the present invention comprises a camera device and a weighing device, wherein the weighing device comprises a floor scale 2; the floor scale 2 is installed in a drainage cavity 1 opened on the ground; a drainage hole 11 is opened at the bottom of the drainage cavity 1, and a sewage pipe 3 is arranged below the drainage cavity 1; one end of the drainage hole 11 is connected to the drainage cavity 1, and the other end is connected to the sewage pipe 3;

[0034] A driving bar 4 is provided between the side of the drainage chamber 1 close to the vehicle direction and the side wall of the floor scale 2, and a supporting plate 5 is fixedly connected to the side wall of the drainage chamber 1 close to the vehicle direction;

[0035] A driving bar 4, wherein the upper end surface of the driving bar 4 is an arc shape inclined outward, and the lower end of the driving bar 4 is connected to a dredging rod 6, and the driving bar 4 squeezes the dredging rod 6 by bearing the pressure of the car;

[0036] A dredging rod 6, wherein a side wall of the dredging rod 6 is provided with a long strip-shaped opening, the interior of the dredging rod 6 is hollow, and a spring 7 is sleeved on the outer wall of the dredging rod 6, and the dredging rod 6 is used to dredge the drainage hole 11 to prevent blockage;

[0037] A spring 7, wherein the upper end of the spring 7 is in contact with the driving bar 4, and the lower end of the spring 7 is fixedly connected to the supporting plate 5;

[0038] During operation, when a shallow pit scale is used, since it is installed in a previously excavated foundation pit, the surrounding water will flow into the foundation pit, causing serious water accumulation in the foundation pit. At present, the scale is generally able to drain water through the water pumps installed on both sides of it, but when the rainfall is relatively heavy and the terrain is low, the drainage efficiency of the water pump cannot keep up with the combined water inflow of rainwater falling from the sky and rainwater flowing from the ground to the foundation pit. Moreover, the sludge attached to the ground and the surface of the scale will be driven into the scale by the water flow, causing blockage of the sewage pipe installed around the scale, affecting the drainage effect of the water pump. If the water pump does not drain the accumulated water in time, the sensor element installed in the pump will be soaked, which will be damaged over time, and ultimately affect the detection accuracy of the scale or even make the scale ineffective.

[0039] When vehicle overload detection is required on rainy days, the vehicle is driven to the side of the present invention. When the wheel passes the surface of the driving strip 4, the wheel applies downward pressure to the driving strip 4, and the driving strip 4 is forced to drive the dredging rod 6 to move downward and squeeze the spring 7. The dredging rod 6 scrapes the sludge attached to the inner wall of the drainage hole 11 when moving. When rainwater flows to the dredging rod 6, the rainwater flows into the inside of the dredging rod through the opening of the dredging rod 6, and then flows into the drainage hole 11. The water flow pushes the sludge on the inner wall of the drainage hole The scraped sludge impacts the sewage pipe 3 and is then washed away by the water flow in the sewage pipe 3; when the wheel leaves the surface of the driving strip 4, the wheel no longer applies pressure to the driving strip 4, the spring 7 is no longer squeezed by the driving strip 4 and starts to reset, the spring 7 drives the driving strip 4 to move upward, the driving strip 4 drives the dredging rod 6 to move upward, and during the movement, the dredging rod 6 scrapes the inner wall of the drainage hole 11 again, so that the sludge attached to the inner wall of the drainage hole 11 falls into the sewage pipe 3 and is washed away by the water flow;

[0040] The present invention arranges a driving bar 4 and a dredging rod 6 between the side wall of the floor scale 2 and the drainage chamber 1, so that each time the car needs to be weighed and passes through the floor scale 2, the driving bar 4 is squeezed to drive the dredging rod 6 to scrape the inner wall of the drainage hole 11, thereby ensuring that the drainage hole 11 is always in a dredged state, preventing sludge from clogging the drainage hole 11, ensuring the normal operation of the floor scale 2, and improving the detection accuracy of the floor scale 2.

[0041] In this embodiment, Figure 2 As shown, the support plate 5 is symmetrically slidably connected with a guide rod 8 with the dredging rod 6 as the center; the guide rod 8 is fixedly connected to the driving bar 4;

[0042] During operation, when a vehicle passes through the driving strip 4, the wheels squeeze the driving strip 4, and the driving strip 4 drives the dredging rod 6 to move downward. At this time, the driving strip 4 drives the symmetrically arranged guide rods 8 to move downward synchronously along the apertures opened in the support plate 5. During the movement, the symmetrically arranged guide rods 8 play a role in positioning and guiding the dredging rod 6.

[0043] By arranging guide rods 8 on both sides of the dredging rod 6, when the driving bar 4 drives the dredging rod 6 to dredge the drainage hole 11, the guide rods 8 can guide and position the dredging rod 6. At the same time, the driving bar 4 can also be evenly stressed, thereby reducing the instability of the driving bar 4 in driving the dredging rod 6.

[0044] In this embodiment, Figure 1 As shown, the lower part of the dredging rod 6 is made of elastic material;

[0045] During operation, the elastic lower part of the dredging rod 6 is made of rubber. When the driving bar 4 drives the dredging rod 6 to move downward, the lower half of the dredging rod 6 made of elastic material extends into the drainage hole 11. When the drainage hole 11 deflects in direction, the dredging rod 6 made of rubber material can adapt to the change of the path of the inner wall of the drainage hole 11, deflect synchronously, and scrape the inner wall of the drainage hole 11.

[0046] By making the lower part of the dredging rod 6 of elastic material, the dredging rod 6 can adapt to the tortuous path of the drainage hole 11 when scraping the sludge on the inner wall of the drainage hole 11 until it enters the sewage pipe 3, thereby improving the adaptability of the dredging rod 6.

[0047] In this embodiment, Figure 1 , Figure 3 As shown, a through hole 61 is formed on the side wall of the dredging rod 6; a protrusion 62 is installed in the through hole 61;

[0048] In this embodiment, Figure 3 As shown, the protrusion 62 is hinged to the dredging rod 6;

[0049] During operation, when the driving bar 4 drives the dredging rod 6 to move downward, under the influence of gravity, the dredging rod 6 will contact the inner wall of one side of the drainage hole 11, and the protrusion 62 installed in the through hole 61 of the dredging rod 6 will directly contact the inner wall of one side of the drainage hole 11. In the process of the dredging rod 6 continuously extending to the bottom of the drainage hole 11, the protrusion 62 can scrape the sludge agglomerates attached to the inner wall of the drainage hole 11. When it rains, the scraped sludge agglomerates will be washed into the sewage pipe 3 by the water flow; even if the sludge enters the inside of the dredging rod 6 through the through hole 61, it will eventually be washed away by the water flow and flow into the sewage and drainage pipe 3;

[0050] By installing a protrusion 62 on the side wall of the dredging rod 6, the sludge lumps attached to the inner wall of the drainage hole 11 can be scraped off by the protrusion 62 when the dredging rod 6 enters the drainage hole 11, thereby further improving the smoothness of the drainage hole 11.

[0051] In this embodiment, Figure 3As shown, the upper end of the drainage hole 11 is fixedly connected with an elastic filter screen 12; the elastic filter screen 12 is provided with small holes; the dredging rod 6 passes through the elastic filter screen 12 and is slidably and sealedly connected with the elastic filter screen 12;

[0052] During operation, when the dredging rod 6 moves upward, the dredging rod 6 slides along the side wall of the hole connected with the elastic filter screen 12. During the sliding process, the dredging rod 6 scrapes the sludge on the inner wall of the drainage hole 11, so that the outer wall thereof is attached with sludge, and the elastic filter screen 12 scrapes the sludge attached to the outer wall of the dredging rod 6; since the elastic filter screen 12 itself has elasticity, during the upward movement of the dredging rod 6, the elastic filter screen 12 drives the middle part of the elastic filter screen 12 to stretch upward synchronously, so that the elastic filter screen 12 is deformed, and when the driving bar 4 is no longer subjected to force and the dredging rod 6 stops moving, the elastic filter screen 12 stretched by the dredging rod 6 quickly returns to its original state, so that the elastic filter screen 12 produces a vibration effect, and the sludge scraped from the dredging rod 6 by the elastic filter screen 12 is shaken off the inner wall of the drainage hole 11 by the vibration of the elastic filter screen 12, and finally washed away by rainwater;

[0053] By arranging an elastic filter screen 12 at the upper end of the drainage hole 11, the sludge attached to the outer wall of the dredging rod 6 can be scraped off by the elastic filter screen 12 when passing through the elastic filter screen 12, thereby maintaining the cleanliness of the outer wall of the dredging rod 6 to a certain extent.

[0054] In this embodiment, Figure 4 As shown, the dredging rod 6 is divided into a No. 1 dredging rod 63 and a No. 2 dredging rod 64; the No. 1 dredging rod 63 and the No. 2 dredging rod 64 are connected by a screw 9;

[0055] During operation, when the No. 2 dredging rod 64 is damaged due to frequent scraping of the drainage hole 11 and needs to be replaced, the driving bar 4 is lifted, and the screw 9 is screwed out from between the No. 1 dredging rod 63 and the No. 2 dredging rod 64 using a tool, and the No. 2 dredging rod 64 is replaced or the surface sludge is cleaned. After replacement or cleaning, the screw 9 is screwed between the No. 1 dredging rod 63 and the No. 2 dredging rod 64 with a tool to fix them;

[0056] By dividing the dredging rod 6 into a No. 1 dredging rod 63 and a No. 2 dredging rod 64 , the No. 2 dredging rod 64 can be replaced after being damaged during use, or the surface of the dredging rod 6 can be cleaned, thereby further ensuring the unobstructed flow of the drainage hole 11 .

[0057] Embodiment 2:

[0058] like Figure 1 , Figure 2As shown, the intelligent vehicle overload detection system for road maintenance of the present invention comprises a camera device and a weighing device, wherein the weighing device comprises a floor scale 2; the floor scale 2 is installed in a drainage cavity 1 opened on the ground; a drainage hole 11 is opened at the bottom of the drainage cavity 1, and a sewage pipe 3 is arranged below the drainage cavity 1; one end of the drainage hole 11 is connected to the drainage cavity 1, and the other end is connected to the sewage pipe 3;

[0059] A driving bar 4 is provided between the side of the drainage chamber 1 close to the vehicle direction and the side wall of the floor scale 2, and a supporting plate 5 is fixedly connected to the side wall of the drainage chamber 1 close to the vehicle direction;

[0060] A driving bar 4, wherein the upper end surface of the driving bar 4 is an arc shape inclined outward, and the lower end of the driving bar 4 is connected to a dredging rod 6, and the driving bar 4 squeezes the dredging rod 6 by bearing the pressure of the car;

[0061] A dredging rod 6, wherein a side wall of the dredging rod 6 is provided with a long strip-shaped opening, the interior of the dredging rod 6 is hollow, and a spring 7 is sleeved on the outer wall of the dredging rod 6, and the dredging rod 6 is used to dredge the drainage hole 11 to prevent blockage;

[0062] A spring 7, wherein the upper end of the spring 7 is in contact with the driving bar 4, and the lower end of the spring 7 is fixedly connected to the supporting plate 5;

[0063] During operation, when a shallow pit scale is used, since it is installed in a previously excavated foundation pit, the surrounding water will flow into the foundation pit, causing serious water accumulation in the foundation pit. At present, the scale is generally able to drain water through the water pumps installed on both sides of it, but when the rainfall is relatively heavy and the terrain is low, the drainage efficiency of the water pump cannot keep up with the combined water inflow of rainwater falling from the sky and rainwater flowing from the ground to the foundation pit. Moreover, the sludge attached to the ground and the surface of the scale will be driven into the scale by the water flow, causing blockage of the sewage pipe installed around the scale, affecting the drainage effect of the water pump. If the water pump does not drain the accumulated water in time, the sensor element installed in the pump will be soaked, which will be damaged over time, and ultimately affect the detection accuracy of the scale or even make the scale ineffective.

[0064] When vehicle overload detection is required on rainy days, the vehicle is driven to the side of the present invention. When the wheel passes the surface of the driving strip 4, the wheel applies downward pressure to the driving strip 4, and the driving strip 4 is forced to drive the dredging rod 6 to move downward and squeeze the spring 7. The dredging rod 6 scrapes the sludge attached to the inner wall of the drainage hole 11 when moving. When rainwater flows to the dredging rod 6, the rainwater flows into the inside of the dredging rod through the opening of the dredging rod 6, and then flows into the drainage hole 11. The water flow pushes the sludge on the inner wall of the drainage hole The scraped sludge impacts the sewage pipe 3 and is then washed away by the water flow in the sewage pipe 3; when the wheel leaves the surface of the driving strip 4, the wheel no longer applies pressure to the driving strip 4, the spring 7 is no longer squeezed by the driving strip 4 and starts to reset, the spring 7 drives the driving strip 4 to move upward, the driving strip 4 drives the dredging rod 6 to move upward, and during the movement, the dredging rod 6 scrapes the inner wall of the drainage hole 11 again, so that the sludge attached to the inner wall of the drainage hole 11 falls into the sewage pipe 3 and is washed away by the water flow;

[0065] The present invention arranges a driving bar 4 and a dredging rod 6 between the side wall of the floor scale 2 and the drainage chamber 1, so that each time the car needs to be weighed and passes through the floor scale 2, the driving bar 4 is squeezed to drive the dredging rod 6 to scrape the inner wall of the drainage hole 11, thereby ensuring that the drainage hole 11 is always in a dredged state, preventing sludge from clogging the drainage hole 11, ensuring the normal operation of the floor scale 2, and improving the detection accuracy of the floor scale 2.

[0066] In this embodiment, Figure 2 As shown, the support plate 5 is symmetrically slidably connected with a guide rod 8 with the dredging rod 6 as the center; the guide rod 8 is fixedly connected to the driving bar 4;

[0067] During operation, when a vehicle passes through the driving strip 4, the wheels squeeze the driving strip 4, and the driving strip 4 drives the dredging rod 6 to move downward. At this time, the driving strip 4 drives the symmetrically arranged guide rods 8 to move downward synchronously along the apertures opened in the support plate 5. During the movement, the symmetrically arranged guide rods 8 play a role in positioning and guiding the dredging rod 6.

[0068] By arranging guide rods 8 on both sides of the dredging rod 6, when the driving bar 4 drives the dredging rod 6 to dredge the drainage hole 11, the guide rods 8 can guide and position the dredging rod 6. At the same time, the driving bar 4 can also be evenly stressed, thereby reducing the instability of the driving bar 4 in driving the dredging rod 6.

[0069] In this embodiment, Figure 1 As shown, the lower part of the dredging rod 6 is made of elastic material;

[0070] During operation, the elastic lower part of the dredging rod 6 is made of rubber. When the driving bar 4 drives the dredging rod 6 to move downward, the lower half of the dredging rod 6 made of elastic material extends into the drainage hole 11. When the drainage hole 11 deflects in direction, the dredging rod 6 made of rubber material can adapt to the change of the path of the inner wall of the drainage hole 11, deflect synchronously, and scrape the inner wall of the drainage hole 11.

[0071] By making the lower part of the dredging rod 6 of elastic material, the dredging rod 6 can adapt to the tortuous path of the drainage hole 11 when scraping the sludge on the inner wall of the drainage hole 11 until it enters the sewage pipe 3, thereby improving the adaptability of the dredging rod 6.

[0072] In this embodiment, Figure 1 , Figure 2 As shown, the dredging rod 6 is connected to the driving bar 4 in a rotational manner, and the dredging rod 6 is connected to the supporting plate 5 in a spiral transmission manner;

[0073] During operation, when the driving bar 4 is squeezed by the car and moves downward, the driving bar 4 drives the dredging rod 6 connected thereto to rotate and move downward at the same time. The dredging rod 6 rotates along the threads arranged in the hole wall of the support plate 5 through the threads arranged on its outer wall. The dredging rod 6 rotates while moving in the drainage hole 11. The protrusions 62 arranged on the side walls of the dredging rod 6 also rotate synchronously and continuously scrape the sludge attached to the inner wall of the drainage hole 11.

[0074] By setting the dredging rod 6 to be rotatably connected to the driving bar 4 and threadedly connected to the support plate 5, the driving bar 4 can drive the dredging rod 6 to rotate in the drainage hole 11, thereby increasing the contact area between the protrusion 62 on the dredging rod 6 and the inner wall of the drainage hole 11, thereby improving the dredging effect of the dredging rod 6 on the drainage hole 11.

[0075] In this embodiment, Figure 3 As shown, the protrusion 62 is hinged to the dredging rod 6;

[0076] During operation, when the driving bar 4 drives the dredging rod 6 to move toward the inside of the drainage hole 11, since the protrusion 62 is rotatably connected to the dredging rod 6, and the dredging rod 6 itself is squeezed and rotated by the driving bar 4 during the downward movement, when the dredging rod 6 rotates, it will be tilted outwards under the influence of centrifugal force, and keep in contact with the inner wall of the drainage hole 11 and scrape the sludge attached to the inner wall of the drainage hole 11;

[0077] By setting the protrusion 62 and the dredging rod 6 to be hinged, the protrusion 62 can be tilted outward due to the centrifugal force when the dredging rod 6 rotates, contact and scrape the inner wall of the drainage hole 11, thereby further increasing the contact area between the protrusion 62 and the inner wall of the drainage hole 11, improving the dredging effect of the dredging rod 6, and keeping the drainage hole 11 unobstructed.

[0078] In this embodiment, Figure 3 As shown, the upper end of the drainage hole 11 is fixedly connected with an elastic filter screen 12; the elastic filter screen 12 is provided with small holes; the dredging rod 6 passes through the elastic filter screen 12 and is slidably and sealedly connected with the elastic filter screen 12;

[0079] During operation, when the dredging rod 6 moves upward, the dredging rod 6 slides along the side wall of the hole connected to the elastic filter screen 12 and the dredging rod 6. During the sliding process, the dredging rod 6 scrapes the sludge on the inner wall of the drainage hole 11, so that the outer wall thereof is attached with sludge, and the elastic filter screen 12 scrapes the sludge attached to the outer wall of the dredging rod 6; since the elastic filter screen 12 is made of iron and has elasticity, during the upward movement of the dredging rod 6, the elastic filter screen 12 drives the middle part of the elastic filter screen 12 to stretch upward synchronously, so that the elastic filter screen 12 is deformed, and when the driving bar 4 is no longer subjected to force and the dredging rod 6 stops moving, the elastic filter screen 12 stretched by the dredging rod 6 quickly returns to its original state, so that the elastic filter screen 12 produces a vibration effect, and the sludge scraped from the dredging rod 6 by the elastic filter screen 12 is shaken off the inner wall of the drainage hole 11 by the vibration of the elastic filter screen 12, and finally washed away by rainwater;

[0080] By arranging an elastic filter screen 12 at the upper end of the drainage hole 11, the sludge attached to the outer wall of the dredging rod 6 can be scraped off by the elastic filter screen 12 when passing through the elastic filter screen 12, thereby maintaining the cleanliness of the outer wall of the dredging rod 6 to a certain extent.

[0081] In this embodiment, Figure 4 As shown, the dredging rod 6 is divided into a No. 1 dredging rod 63 and a No. 2 dredging rod 64; the No. 1 dredging rod 63 and the No. 2 dredging rod 64 are connected by a screw 9;

[0082] During operation, when the No. 2 dredging rod 64 is damaged due to frequent scraping of the drainage hole 11 and needs to be replaced, the driving bar 4 is lifted, and the screw 9 is screwed out from between the No. 1 dredging rod 63 and the No. 2 dredging rod 64 using a tool, and the No. 2 dredging rod 64 is replaced or the surface sludge is cleaned. After replacement or cleaning, the screw 9 is screwed between the No. 1 dredging rod 63 and the No. 2 dredging rod 64 with a tool to fix them;

[0083] By dividing the dredging rod 6 into a No. 1 dredging rod 63 and a No. 2 dredging rod 64 , the No. 2 dredging rod 64 can be replaced after being damaged during use, or the surface of the dredging rod 6 can be cleaned, thereby further ensuring the unobstructed flow of the drainage hole 11 .

[0085] like Figure 1 , Figure 2As shown, the intelligent vehicle overload detection system for road maintenance of the present invention comprises a camera device and a weighing device, wherein the weighing device comprises a floor scale 2; the floor scale 2 is installed in a drainage cavity 1 opened on the ground; a drainage hole 11 is opened at the bottom of the drainage cavity 1, and a sewage pipe 3 is arranged below the drainage cavity 1; one end of the drainage hole 11 is connected to the drainage cavity 1, and the other end is connected to the sewage pipe 3;

[0086] A driving bar 4 is provided between the side of the drainage chamber 1 close to the vehicle direction and the side wall of the floor scale 2, and a supporting plate 5 is fixedly connected to the side wall of the drainage chamber 1 close to the vehicle direction;

[0087] A driving bar 4, wherein the upper end surface of the driving bar 4 is an arc shape inclined outward, and the lower end of the driving bar 4 is connected to a dredging rod 6, and the driving bar 4 squeezes the dredging rod 6 by bearing the pressure of the car;

[0088] A dredging rod 6, wherein a side wall of the dredging rod 6 is provided with a long strip-shaped opening, the interior of the dredging rod 6 is hollow, and a spring 7 is sleeved on the outer wall of the dredging rod 6, and the dredging rod 6 is used to dredge the drainage hole 11 to prevent blockage;

[0089] A spring 7, wherein the upper end of the spring 7 is in contact with the driving bar 4, and the lower end of the spring 7 is fixedly connected to the supporting plate 5;

[0090] During operation, when a shallow pit scale is used, since it is installed in a previously excavated foundation pit, the surrounding water will flow into the foundation pit, causing serious water accumulation in the foundation pit. At present, the scale is generally able to drain water through the water pumps installed on both sides of it, but when the rainfall is relatively heavy and the terrain is low, the drainage efficiency of the water pump cannot keep up with the combined water inflow of rainwater falling from the sky and rainwater flowing from the ground to the foundation pit. Moreover, the sludge attached to the ground and the surface of the scale will be driven into the scale by the water flow, causing blockage of the sewage pipe installed around the scale, affecting the drainage effect of the water pump. If the water pump does not drain the accumulated water in time, the sensor element installed in the pump will be soaked, which will be damaged over time, and ultimately affect the detection accuracy of the scale or even make the scale ineffective.

[0091] When vehicle overload detection is required on rainy days, the vehicle is driven to the side of the present invention. When the wheel passes the surface of the driving strip 4, the wheel applies downward pressure to the driving strip 4, and the driving strip 4 is forced to drive the dredging rod 6 to move downward and squeeze the spring 7. The dredging rod 6 scrapes the sludge attached to the inner wall of the drainage hole 11 when moving. When rainwater flows to the dredging rod 6, the rainwater flows into the inside of the dredging rod through the opening of the dredging rod 6, and then flows into the drainage hole 11. The water flow pushes the sludge on the inner wall of the drainage hole The scraped sludge impacts the sewage pipe 3 and is then washed away by the water flow in the sewage pipe 3; when the wheel leaves the surface of the driving strip 4, the wheel no longer applies pressure to the driving strip 4, the spring 7 is no longer squeezed by the driving strip 4 and starts to reset, the spring 7 drives the driving strip 4 to move upward, the driving strip 4 drives the dredging rod 6 to move upward, and during the movement, the dredging rod 6 scrapes the inner wall of the drainage hole 11 again, so that the sludge attached to the inner wall of the drainage hole 11 falls into the sewage pipe 3 and is washed away by the water flow;

[0092] The present invention arranges a driving bar 4 and a dredging rod 6 between the side wall of the floor scale 2 and the drainage chamber 1, so that each time the car needs to be weighed and passes through the floor scale 2, the driving bar 4 is squeezed to drive the dredging rod 6 to scrape the inner wall of the drainage hole 11, thereby ensuring that the drainage hole 11 is always in a dredged state, preventing sludge from clogging the drainage hole 11, ensuring the normal operation of the floor scale 2, and improving the detection accuracy of the floor scale 2.

[0093] In this embodiment, Figure 1 As shown, the bottom wall height of the drainage cavity 1 increases as it moves away from the drainage hole 11;

[0094] During operation, when rain drops onto the ground, the rain will flow into the drainage cavity 1 along the gap between the ground and the scale 2. Since the height of the bottom wall of the drainage cavity 1 increases as it moves away from the drainage hole 11, the rain will flow into the drainage hole 11 along the inclined bottom wall of the drainage cavity 1, and finally flow into the sewage pipe 3.

[0095] By setting the bottom wall of the drainage cavity 1 to have a height that increases as it moves away from the drainage hole 11, rainwater in the drainage cavity 1 can flow into the drainage hole 11 in time, reducing the accumulation of rainwater in the drainage cavity 1 and causing flooding, thereby ensuring that the present invention can be used normally even on rainy days with heavy rainfall.

[0098] A driving bar 4 is provided between the side of the drainage chamber 1 close to the vehicle direction and the side wall of the floor scale 2, and a supporting plate 5 is fixedly connected to the side wall of the drainage chamber 1 close to the vehicle direction;

[0099] A driving bar 4, wherein the upper end surface of the driving bar 4 is an arc shape inclined outward, and the lower end of the driving bar 4 is connected to a dredging rod 6, and the driving bar 4 squeezes the dredging rod 6 by bearing the pressure of the car;

[0100] A dredging rod 6, wherein a side wall of the dredging rod 6 is provided with a long strip-shaped opening, the interior of the dredging rod 6 is hollow, and a spring 7 is sleeved on the outer wall of the dredging rod 6, and the dredging rod 6 is used to dredge the drainage hole 11 to prevent blockage;

[0101] A spring 7, wherein the upper end of the spring 7 is in contact with the driving bar 4, and the lower end of the spring 7 is fixedly connected to the supporting plate 5;

If the water pump does not drain the accumulated water in time, the sensor element installed in the pump will be soaked, which will be damaged over time, and ultimately affect the detection accuracy of the scale or even make the scale ineffective.
