Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a wastewater recycling device for road construction. Background Technology

[0002] During road construction, construction machinery vehicles are indispensable core equipment, undertaking key tasks such as muck transportation, material transfer, and site preparation. Their operating efficiency directly affects the construction progress. However, most road construction projects are currently constrained by the construction period and have a short construction cycle. Construction sites often prioritize the main project advancement and do not have dedicated cleaning equipment for construction machinery vehicles, resulting in a prominent contradiction between construction progress and environmental management and water resource protection.

[0003] Construction sites are mostly earthwork environments. Loose soil, after being compacted by vehicles and soaked by rainwater, easily adheres to vehicle wheels, body, and chassis. When vehicles carrying a large amount of mud, dust, and other impurities leave the construction site, the impurities will fall off due to vibrations, polluting the surrounding public roads. This not only affects road cleanliness and traffic safety but also requires a lot of manpower and resources for road washing.

[0004] Water resources are a fundamental resource for human survival and development. my country's per capita water resources are far below the world average, and the problem of water shortage is becoming increasingly prominent. Conserving and protecting water resources has become a common responsibility of the whole society and an inevitable requirement for sustainable development. However, at present, washing roads after pollution and cleaning construction vehicles rely on a large amount of fresh water resources, which are mostly used once and without recycling measures, resulting in serious waste of water resources. At the same time, manual vehicle cleaning is time-consuming and labor-intensive, which not only increases labor costs but also delays vehicle turnover and affects construction efficiency.

[0005] Therefore, it is necessary to invent a wastewater recycling device for road construction to solve the above problems. Summary of the Invention

[0006] Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a wastewater recycling device for road construction, which solves the problems of wastewater from cleaning construction vehicles and poor on-site environmental protection.

[0008] Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solution: a wastewater recycling device for road construction, comprising a first assembly component, a third assembly component being provided at one end of the first assembly component, and cleaning components being symmetrically provided on both sides of the third assembly component;

[0010] The first assembly component includes a first base, and a rectangular groove is formed inside the first base;

[0011] The third assembly component includes a second base, both ends of which abut against one end of the first base;

[0012] The second base has a rectangular groove inside, and collection slots are symmetrically formed on both sides of the rectangular groove. Telescopic rods are provided at both ends of the two collection slots, and pressure plates are provided at the other ends of the multiple telescopic rods. The pressure plates are movably connected to the rectangular groove.

[0013] The first base and the second base are combined to form a water tank for storing liquid. A cavity for storing liquid is provided between the pressure plate and the second base. By squeezing the pressure plate, the liquid in the cavity is squeezed and transported into the cleaning component, thereby forming a high-pressure water jet to wash the wheels of passing vehicles. The water jet is collected by the water tank, thus achieving a recycling effect. The top of the pressure plate is provided with second arc-shaped grooves at equal intervals. The wave shape of the second arc-shaped grooves causes continuous up-and-down vibration when the vehicle passes at low speed. Combined with the washing of the high-pressure water jet, this improves the cleaning effect on the vehicle body and wheels.

[0014] Furthermore, a triangular protrusion is provided at the top center of the rectangular groove, a groove adapted to the top of the rectangular groove is provided at the bottom of the pressure plate, and a third arc-shaped groove adapted to the pressure plate is symmetrically provided at both ends of the top of the second base.

[0015] Furthermore, the collection tank has symmetrical first inlets at both ends, and the second base has symmetrical first outlets on both sides of the top. The first outlets are connected to the first inlets. The first inlets are horizontally higher than the collection tank. A protruding block is fixedly installed inside the first inlet, and one side of the protruding block is inclined.

[0016] Furthermore, a second inlet is provided on one side of the middle of the collection tank, and a second outlet is symmetrically provided on one side of the second base. The second outlet is connected to the second inlet, and a blocking block is inserted into the second outlet. Second inclined grooves are symmetrically provided on both sides of the second base.

[0017] Furthermore, the cleaning component includes a vertical tube with a limiting groove at the bottom and nozzles equidistantly arranged on one side of the vertical tube, all of which are inclined downwards.

[0018] Furthermore, a flow-limiting component is provided at the bottom end of the vertical pipe. The flow-limiting component includes an insert block, a flow guide hole is provided in the middle of the top of the insert block, a filter screen is provided inside the insert block below the flow guide hole, the bottom of the insert block is inserted into the first outlet, the top of the insert block abuts against the bottom of the insert block, a rectangular plate is provided at the top, a limit rod is movably passed through the middle of the top of the rectangular plate, a sealing plate is provided at the bottom end of the limit rod, and a compression spring is sleeved on the outer peripheral surface of the limit rod. The two ends of the compression spring abut against one side of the sealing plate and one side of the rectangular plate, respectively.

[0019] Furthermore, a second assembly component is provided inside the rectangular groove. The second assembly component includes an inclined plate with a sloping top. A second anti-slip groove is laterally formed on the top of the inclined plate, and a guide groove is inclinedly formed on the top of the second anti-slip groove. The second anti-slip groove and the guide groove are staggered. A first arc-shaped groove adapted to the pressure plate is formed at equal intervals above the middle of the end of the inclined plate near the second base.

[0020] Furthermore, a first inclined groove is symmetrically opened on both sides of one end of the rectangular groove, and a collection box is symmetrically arranged on both sides of the first base near the first inclined groove. A collection basket is arranged inside the two collection boxes. The top of the other end of the first base is inclined, and a first anti-slip groove is equidistantly opened on the top of the inclined surface.

[0021] Furthermore, a connecting block is fixedly installed at one end of the first base near the collection box. A V-shaped groove is provided on the top of the connecting block. Connecting grooves are symmetrically provided at both ends of the second base. Protrusions that fit the V-shaped grooves are provided at the bottom of the two connecting grooves. The connecting block is adapted to connect with the connecting grooves.

[0022] Furthermore, the first inclined groove, the guide groove, and the second inclined groove intersect to form a groove for collecting solid impurities, and the bottom of the groove is connected to the inner cavity of the collection box.

[0023] Beneficial effects

[0024] The present invention has the following beneficial effects:

[0025] 1. The design incorporates a full-process washing system for construction vehicles entering and exiting the site. After vehicles enter, they are thoroughly washed by high-pressure water jets, and the vibration generated by the wave-shaped trough surface removes mud and impurities adhering to the wheels, body, and chassis. This ensures that no obvious pollutants remain on the vehicles when they leave, thus solving the problem of existing construction vehicles leaving the site with mud and polluting the roads. This eliminates the need for subsequent investment of a large amount of manpower and resources to clean the external roads, reducing the manpower and material costs of road cleaning.

[0026] 2. The first base and the second base are combined to form a water tank, which collects all the wastewater generated during rinsing. After being filtered by the filter screen and impurities are separated, the wastewater is returned to the cavity through the second inlet for recycling. There is no need to frequently add new water. At the same time, the internal water resources can be reused after being purified by gravity and the filter components. Compared with the traditional extensive cleaning method, it can significantly reduce water consumption, practice the concept of water conservation and protection, and alleviate the pressure caused by water shortage.

[0027] 3. The device adopts a modular assembly design. During the preparation stage, only the assembly of each component and the injection of clean water are required before it can be put into use. It is easy to operate. The cleaning process relies on the weight of the vehicle itself to achieve high-pressure water supply and rinsing. No additional power equipment or manual operation is required for rinsing. Impurities are collected by using a collection basket in conjunction with a second outlet, which makes cleaning convenient and does not require disassembling the entire device. This reduces labor input and avoids the problem of delaying the turnover of construction vehicles due to manual cleaning, thus indirectly improving the progress of road construction.

[0028] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0046] Please see Figures 1-11 The present invention provides a technical solution: a wastewater recycling device for road construction, including a first assembly component 1, one end of which is fixedly connected to a third assembly component 3. The two work together to achieve the functions of wastewater collection and high-pressure water supply. At the same time, cleaning components 4 are symmetrically arranged on both sides of the third assembly component 3 for accurately washing the wheels and body of passing construction vehicles to ensure the cleaning effect.

[0047] The first assembly component 1 includes a horizontally arranged first base 101. The first base 101 is made of high-strength alloy material, which can withstand the heavy pressure of construction vehicles and is not easily deformed or damaged. In order to realize the collection and storage of sewage, a rectangular groove 102 is opened inside the first base 101 along its length direction. The rectangular groove 102 is opened to provide storage space for subsequent sewage recycling.

[0048] The third assembly component 3 includes a second base 301 that matches the specifications of the first base 101. Both ends of the second base 301 are tightly abutted against one end of the first base 101. The joints of the two are abutted against each other to ensure that sewage will not leak from the joint gap, thus ensuring the sealing and practicality of the device.

[0049] The second base 301 has a rectangular groove 3010 inside, which serves as the installation and movement space for the pressure plate 306. Symmetrical collection troughs 304 are provided on both sides of the groove. The collection troughs 304 are mainly used to collect wastewater after rinsing the cleaning component 4 and guide the wastewater to a designated area for recycling. Telescopic rods 305 are fixedly installed at both ends of the two collection troughs 304. Multiple telescopic rods 305 are symmetrically distributed, and their other ends are connected to the pressure plate 306. The pressure plate 306 is movably fitted into the rectangular groove 3010 and can move up and down inside the rectangular groove 3010. The telescopic rods 305 limit the movement direction of the pressure plate 306 to ensure smooth movement and prevent deviation that could affect the squeezing and water supply effect.

[0050] After the first base 101 and the second base 301 are combined, they form a complete water tank for storing cleaning liquid. This water tank can collect all the wastewater after the cleaning components 4 wash the vehicle, achieving centralized wastewater recycling. At the same time, a sealed cavity for storing liquid is formed between the pressure plate 306 and the second base 301. When the construction vehicle passes over the top of the pressure plate 306 at low speed, the weight of the vehicle will push the pressure plate 306 downward, thereby squeezing the cleaning liquid in the cavity. The liquid is then transported under high pressure to the cleaning components 4 on both sides, forming a high-pressure water jet to thoroughly clean the wheels of the passing vehicle. The directional rinsing process allows the water jets to flow along the vehicle body and wheels into the water tank, achieving the recycling of cleaning liquid and significantly reducing water waste. In addition, the top of the pressure plate 306 is provided with second arc-shaped grooves 3060 at equal intervals. The second arc-shaped grooves 3060 are distributed in a wave shape, so that when the vehicle passes at low speed, the wheels will generate continuous up and down vibrations along the wave-shaped groove surface, causing the vehicle body to vibrate slightly in sync. This makes it easier for mud and impurities adhering to the vehicle body and wheels to fall off. Combined with the rinsing of the high-pressure water jet, this significantly improves the cleaning effect of the vehicle body and wheels, ensuring that there are no obvious pollutants adhering to the vehicle when it leaves.

[0051] It should be noted that the first assembly component 1, the second assembly component 2, the third assembly component 3, and the cleaning component 4 all adopt a modular design. Each component can be quickly assembled and disassembled to adapt to road construction sites of different sizes, taking into account both practicality and flexibility. This solves the problems of poor adaptability and cumbersome disassembly and assembly of traditional fixed cleaning equipment. The depth and volume of the rectangular trough 102 have been reasonably calculated to meet the sewage storage needs of washing multiple construction vehicles at a time, without the need for frequent water replenishment. The telescopic rod 305 adopts a telescopic hydraulic rod and is equipped with a spring, which has good telescopic flexibility and load-bearing capacity. It can not only move up and down with the pressure plate 306, but also quickly push the pressure plate 306 to reset after the vehicle leaves, ensuring continuous operation of the device.

[0052] A triangular protrusion is provided in the middle of the top of the rectangular groove 3010. Correspondingly, a groove adapted to the triangular protrusion on the bottom of the pressure plate 306 is provided. After the bottom of the pressure plate 306 is attached to the top of the rectangular groove 3010, it can enhance the stability of the pressure plate 306 after resetting. At the same time, the triangular protrusion can limit the movement of the pressure plate 306 and ensure the stability of the extrusion process. In addition, the top two ends of the second base 301 are symmetrically provided with third arc-shaped grooves 312 adapted to the pressure plate 306. The shape of the third arc-shaped groove 312 matches the end shape of the pressure plate 306. When the pressure plate 306 moves down and is attached to the top of the rectangular groove 3010, the second arc-shaped groove 3060 and the third arc-shaped groove 312 on the top of the pressure plate 306 form a continuous wave-shaped groove surface, avoiding jamming and facilitating the smooth passage of vehicles.

[0053] The collection tank 304 has symmetrically arranged first inlets 302 at both ends, which serve as the output channels for the cleaning liquid. The second base 301 has symmetrically arranged first outlets 303 on both sides of its top. The first outlets 303 are connected to the first inlets 302 to form a complete channel for liquid transportation, ensuring that the high-pressure liquid squeezed in the cavity can be smoothly transported to the cleaning component 4. In order to facilitate the rapid flow of liquid and avoid the accumulation of impurities, the horizontal position of the first inlet 302 is higher than that of the collection tank 304, and the liquid flow is promoted by gravity. At the same time, a protrusion 3020 is fixedly installed inside the first inlet 302. One side of the protrusion 3020 is inclined, which can block some larger particles of impurities from entering the first inlet 302. It can effectively block large particles of impurities without hindering the normal flow of liquid. Impurities can slide down the inclined surface to the bottom of the collection tank 304 for easy subsequent cleaning.

[0054] A second inlet 307 is provided on one side of the middle of the collection tank 304, and a second outlet 308 is symmetrically provided on one side of the second base 301. The second outlet 308 is connected to the second inlet 307 and is used to collect solid impurity particles in the collection tank 304. When the device needs to change the water or clean the sewage, the second outlet 308 can be opened to discharge the sewage. In order to facilitate the control of the opening and closing of the second outlet 308, a blocking block 309 is inserted into the second outlet 308. The blocking block 309 is made of sealing material. After being inserted, it can seal the second outlet 308 to prevent liquid leakage. After being pulled out, the sewage can be discharged. In addition, a second inclined groove 310 is symmetrically provided on both sides of the second base 301. The second inclined groove 310 is used to collect solid impurity particles in the sewage and prevent impurities from accumulating on the top of the second base 301.

[0055] The cleaning component 4, as the flushing execution part of the device, is used to precisely flush construction vehicles. It includes a vertically arranged vertical pipe 401, which is made of corrosion-resistant and high-strength material and can withstand the impact of high-pressure liquid. A limiting groove 402 is opened at the bottom of the vertical pipe 401. The limiting groove 402 is used to cooperate with the flow limiting component to fix and limit the vertical pipe 401, ensuring that the vertical pipe 401 is firmly installed and will not shake during the flushing process. Multiple nozzles 403 are evenly arranged on one side of the vertical pipe 401. The multiple nozzles 403 are evenly distributed, and the angle of each nozzle 403 is inclined downward. This angle setting allows the high-pressure water jet to be accurately aimed at the vehicle wheels and the bottom of the vehicle body, ensuring the flushing effect.

[0056] A flow-limiting component is installed at the bottom of the vertical pipe 401. This component primarily controls the liquid delivery speed, filters impurities, prevents nozzle 403 from clogging, and ensures stable liquid delivery. The flow-limiting component includes an insert 404 that fits the bottom of the vertical pipe 401. A guide hole 4040 is located in the center of the top of the insert 404. The guide hole 4040 guides the liquid in the collection tank 304 into the vertical pipe 401, providing high-pressure liquid to the nozzle 403. A filter is installed inside the insert 404 below the guide hole 404. Filter 4041 is made of fine filter material, effectively filtering out solid impurities such as mud and sand from the liquid. Filter 4041 features a detachable design, facilitating regular cleaning and replacement by operators to prevent clogging and ensure unimpeded liquid delivery. It also prevents impurities from entering the vertical pipe 401 and nozzle 403, thus avoiding channel blockage and extending the device's lifespan. The bottom of the insert 404 connects to the first outlet 303, ensuring smooth liquid flow from the first outlet 303 into the insert 404. 4. The top of the insert block 404 abuts against the bottom of the vertical pipe 401, achieving a tight connection between the vertical pipe 401 and the insert block 404 to prevent liquid leakage. A rectangular plate 405 is provided on the top of the insert block 404, and a limiting rod 406 movably passes through the middle of the top of the rectangular plate 405. The limiting rod 406 can move up and down within the rectangular plate 405. A sealing plate 407 is fixedly connected to the bottom end of the limiting rod 406. The sealing plate 407 is used to control the opening and closing of the guide hole 4040. A compression spring 408 is sleeved on the outer peripheral surface of the limiting rod 406. The two ends of the compression spring 408 abut against one side of the sealing plate 407 and one side of the rectangular plate 405, respectively. Under the elastic action of the compression spring 408, the sealing plate 407 is always tightly attached to the bottom of the guide hole 4040. When the liquid pressure in the cavity reaches a certain value, it will push the sealing plate 407 to move upward, the compression spring 408 will be compressed, the guide hole 4040 will open, and the liquid will pass through smoothly. When the pressure is insufficient, the sealing plate 407 will reset under the action of the spring force, closing the guide hole 4040 and achieving the flow restriction effect.

[0057] The rectangular trough 102 houses a second assembly component 2, which primarily assists in the smooth movement of construction vehicles and the collection of wastewater and impurities after rinsing. This assembly component includes an inclined plate 201 with a sloping top. This sloping design facilitates the slow movement of construction vehicles and guides the wastewater after rinsing down the slope into the rectangular trough 102 for collection. A second anti-slip groove 202 is laterally formed on the top of the inclined plate 201. This anti-slip groove 202 increases the friction between the wheels and the inclined plate 201, preventing vehicles from slipping on the slope and ensuring safe passage. The top of the second anti-slip groove 202 is inclined with a guide groove 203. The guide groove 203 is staggered with the second anti-slip groove 202, which can not only further enhance the anti-slip effect, but also guide the sewage on the top of the inclined plate 201 to flow quickly into the rectangular groove 102. In addition, the middle of the end of the inclined plate 201 near the second base 301 is equidistantly provided with a first arc groove 204 that matches the pressure plate 306. The first arc groove 204 is connected with the second arc groove 3060 and the third arc groove 312 on the top of the pressure plate 306 to ensure that the vehicle can smoothly transition from the inclined plate 201 to the pressure plate 306, avoiding jamming, and at the same time not affecting the up and down movement of the pressure plate 306.

[0058] A first inclined groove 103 is symmetrically provided on both sides of one end of a rectangular trough 102. The first inclined groove 103 is used to guide the sewage and mixed solid impurities collected in the rectangular trough 102 into a collection box 104, achieving preliminary separation of impurities and sewage. Collection boxes 104 are symmetrically arranged on both sides of the first base 101 near the first inclined groove 103. The two collection boxes 104 are used to collect solid impurities generated during the rinsing process, preventing impurities from accumulating in the water tank and clogging the channel, thus affecting sewage recycling. The interior of the two collection boxes 104 is equipped with a collection mechanism. The collection basket 105 adopts a hollow mesh structure, which can collect solid impurities in the basket and allow sewage to flow back through the basket, making it easy to clean the impurities later without disassembling the entire device, saving manpower. The top of the other end of the first base 101 is sloping, which facilitates the entry and exit of construction vehicles. At the same time, the top of the sloping surface is provided with first anti-slip grooves 106 at equal intervals. The first anti-slip grooves 106 can increase the friction between the wheels and the sloping surface, preventing the vehicle from slipping when driving out, and further ensuring traffic safety.

[0059] To ensure a firm and well-sealed connection between the first base 101 and the second base 301, a connecting block 107 is fixedly installed at one end of the first base 101 near the collection box 104. The top of the connecting block 107 has a V-shaped groove. Correspondingly, the two ends of the second base 301 have symmetrical connecting grooves 311. The bottom of the two connecting grooves 311 is provided with protrusions that fit the V-shaped grooves. The connecting block 107 and the connecting grooves 311 achieve precise connection through the cooperation of the V-shaped grooves and the protrusions. This connection method not only enhances the connection stability of the two and prevents loosening during use, but also improves the sealing of the connection point, prevents sewage from leaking from the connection gap, ensures the overall sealing of the device, and provides a reliable structural guarantee for sewage recycling.

[0060] The first inclined groove 103, the guide groove 203, and the second inclined groove 310 intersect to form a concentrated groove for collecting solid impurities. This groove is funnel-shaped, which facilitates the collection of all solid impurities generated during the rinsing process. The bottom of the groove is connected to the inner cavity of the collection box 104, so that the collected solid impurities can fall smoothly into the collection basket 105 inside the collection box 104 under the action of gravity. This achieves centralized collection and separation of impurities, prevents impurities from entering the water tank and clogging the liquid conveying channel, reduces the pollution of circulating sewage by impurities, ensures the cleanliness of the circulating liquid, further guarantees the rinsing effect, and extends the service life of the device.

[0061] Working principle:

[0062] First, assemble the first assembly component 1, the second assembly component 2, and the third assembly component 3. Then, inject clean water at a fixed level into the formed water tank. Finally, assemble the cleaning component 4 to complete the preparation work for cleaning.

[0063] When the construction vehicle is about to enter the device, it slowly drives towards the inclined surface at one end of the first assembly component 1. The first anti-slip groove 106 opened at the top of the inclined surface can effectively increase the friction of the wheels and prevent the vehicle from slipping when entering, ensuring that the vehicle enters smoothly. The vehicle continues to drive and enters the second assembly component 2 inside the rectangular groove 102. It slowly moves forward along the inclined surface of the inclined plate 201. The inclination angle of the inclined plate 201 not only avoids the difficulty of the vehicle climbing the slope, but also guides the sewage and impurities generated by subsequent washing to flow along the inclined surface. At this time, the second anti-slip groove 202 at the top of the inclined plate 201 and the staggered guide groove 203 work together. The second anti-slip groove 202 increases the friction of the wheels and ensures the smooth movement of the vehicle. The guide groove 203 guides a small amount of mud and water pollutants dripping from the surface of the vehicle into the rectangular groove 102.

[0064] The vehicle continues to move, smoothly transitioning to the top of the pressure plate 306 via the first arc-shaped groove 204 and the third arc-shaped groove 312 at the end of the inclined plate 201. The first arc-shaped groove 204, the second arc-shaped groove 3060, and the third arc-shaped groove 312 form a continuous wavy groove surface, preventing the vehicle from getting stuck when passing through. Due to the pressure of the vehicle's own weight, the pressure plate 306 moves downward along the rectangular groove 3010, and the telescopic rods 305 on both sides retract synchronously, limiting the direction of movement of the pressure plate 306 and ensuring its smooth downward movement. The triangular protrusion at the top of the rectangular groove 3010 precisely fits the matching groove at the bottom of the pressure plate 306. As the pressure plate 306 continues to move downward, the initially added cleaning water in the sealed cavity... The recycled wastewater is squeezed to form a high-pressure liquid and is transported to the cleaning components 4 on both sides through the first inlet 302 at both ends of the collection tank 304 and the first outlet 303 at the top of the second base 301. At the same time, the pressure of the high-pressure liquid exceeds the preset value, pushing the sealing plate 407 to move upward, the compression spring 408 is compressed, the guide hole 4040 is opened, and the liquid passes smoothly through the filter screen 4041 inside the insert block 404. The filter screen 4041 filters out the fine impurities in the liquid to prevent clogging of the nozzle 403. After entering the vertical pipe 401, it finally passes through the downward-sloping nozzle 403 on the vertical pipe 401 to form a high-pressure water jet, which is precisely aimed at the vehicle wheels, the bottom of the body and the sides for washing.

[0065] When the vehicle is traveling at low speed on top of the pressure plate 306, the first arc groove 204, the second arc groove 3060, and the third arc groove 312 form a continuous wave-shaped groove surface, causing the wheels to vibrate continuously up and down, which in turn causes the vehicle body to vibrate slightly in sync. This makes it easier for mud and impurities adhering to the vehicle body and wheels to fall off. Combined with the rinsing of the high-pressure water jet, the cleaning effect is improved. During the rinsing process, some of the sewage and solid impurities washed down flow along the second inclined grooves 310 on both sides of the second base 301 into the funnel-shaped groove formed by the intersection of the first inclined groove 103, the guide groove 203, and the second inclined groove 310. The other part flows along the vehicle body into the water tank formed by the combination of the first base 101 and the second base 301, thus achieving comprehensive collection of sewage.

[0066] Under the influence of gravity, solid impurities in the funnel-shaped groove fall into the collection basket 105 in the collection box 104 through the guide plate at the bottom of the groove. The second inlet 307 in the middle of the collection tank 304 collects impurities in the sewage. After the impurities accumulate, they can be removed by opening the blocking block 309 at one end of the second outlet 308.

[0067] After the vehicle has completely moved away from the pressure plate 306, the telescopic rod 305 pushes the pressure plate 306 upward to reset, the pressure in the sealed cavity disappears, the sealing plate 407 resets under the elastic action of the compression spring 408, closing the guide hole 4040, the liquid in the vertical pipe 401 cannot flow back, and at the same time the nozzle 403 stops rinsing, the device returns to its initial state, waiting for the next construction vehicle to enter.

[0068] When the construction vehicle leaves the device, it passes through the inclined surface at the other end of the first assembly component 1 again. The first anti-slip groove 106 further ensures that the vehicle drives out smoothly, completing the entire cleaning and sewage circulation process. In addition, the staff can periodically pull out the collection basket 105 through the collection box 104 to clean the solid impurities inside. When the device needs to be changed or thoroughly cleaned, the block block 309 in the second outlet 308 is pulled out to discharge sewage and impurities deposited at the bottom. The operation is convenient and efficient.
