Description

Technical Field

[0001] The embodiments of the present invention relate to the field of car wash platform technology, specifically, to a car wash platform for construction sites. Background Technology

[0002] In the construction industry, transport vehicles are often used to transport various building materials. After the vehicles are used, they often leave behind sand, gravel, debris, and dust rich in sand, cement, and other contaminants. If these vehicles are driven from the construction site into the outside environment, they can easily carry sand, gravel, cement, and other materials from the construction site into the outside environment, causing damage to the environment and reducing the environmental friendliness of construction. Therefore, construction companies in the current technology generally equip themselves with special vehicle washing platforms to clean the building materials adhering to the surfaces of the transport vehicles.

[0003] Existing car wash platforms typically use a cement base as the platform's foundation, and then use steel to construct the washing area. Currently, in order to save water, car wash platforms usually filter the wastewater after washing transport vehicles and reuse it. However, when directly cleaning transport vehicles in one go, the wastewater is quite turbid and difficult to filter thoroughly, affecting the recyclability of the wastewater. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a car wash platform for construction sites, which solves the technical problem that wastewater generated during the cleaning of transport vehicles by existing car wash platforms is not easy to recycle.

[0005] The present invention provides a car washing platform for construction sites, comprising a cement base, wherein a bottom trough is provided within the cement base, and further comprising: The preliminary cleaning area is set up on one side of the bottom tank. The preliminary cleaning area is equipped with a preliminary water collection structure to perform the first cleaning of the transport vehicle. The preliminary water collection structure has the function of filtering sand and draining water. The secondary cleaning area is located in the middle of the bottom tank. A cleaning platform that can move longitudinally is provided in the secondary cleaning area. A water collection and filtration structure is provided between the primary cleaning area and the secondary cleaning area. The water collection and filtration structure can collect and filter the wastewater generated by the primary and secondary cleaning of the transport vehicle. The cleaning platform can improve the filtration speed of the wastewater by means of the weight of the transport vehicle. The drainage area is located on the other side of the top of the bottom trough. A drainage collection structure is provided in the drainage area to collect the wastewater generated during the final washing of the transport vehicle. A filtered water storage tank and a clean water storage tank are provided at the bottom of the drainage collection structure. Both the water collection and filtration structure and the drainage collection structure are connected to the filtered water storage tank.

[0006] To collect the wastewater generated from the initial cleaning of transport vehicles, the initial water collection structure further includes a water collection tank and a sloping connecting trough frame. The water collection tank is fixedly connected to the bottom tank. The side of the water collection tank near the secondary cleaning area is set as a drainage area. Multiple drainage outlets are provided in the drainage area. The bottom of the water collection tank is fixedly connected to the sloping connecting trough frame, which communicates with the drainage area.

[0007] In order to collect cleaning water and filter wastewater, the cleaning platform further includes an installation tank and a squeeze filtration assembly. The installation tank slides longitudinally in the middle of the bottom tank. A water collection plate is fixedly connected to the top of the installation tank. The inner bottom wall of the installation tank is sloped. The squeeze filtration assembly that cooperates with the water collection and filtration structure is fixedly connected to the bottom of the installation tank.

[0008] To collect and filter wastewater from the preliminary cleaning area and the secondary cleaning area, the water collection and filtration structure further includes a connecting water cylinder, a receiving tank, and curved filter cores. The connecting water cylinder is fixedly connected to the bottom tank and runs through the preliminary cleaning area and the secondary cleaning area. The sloping connecting tank frame is connected to one side of the connecting water cylinder. A telescopic flexible tube connects the lowest point of the inner bottom wall of the mounting tank to the connecting water cylinder. Two receiving tanks are provided, rotatably mounted in the bottom tank, and can be moved out of the bottom tank. The filtered water from the receiving tank is transported to the filtered water storage tank. The curved filter cores are installed in the receiving tank. The squeeze filtration assembly is used to press and filter the two curved filter cores. A wastewater supply assembly is provided between the connecting water cylinder and the two curved filter cores.

[0009] In order to add the filtered water into the filtered water storage tank, the bottom of the filtered water storage tank is connected to a water receiving tank, which is located on one side of the bottom of the two receiving tanks, and the receiving tank has multiple water outlets in the area on the upper side of the water receiving tank.

[0010] To expedite the filtration of the curved filter cartridge and accelerate wastewater filtration, the extrusion filtration assembly further includes extrusion plates and support protrusions. Two extrusion plates are provided, each located on the upper side of the corresponding curved filter cartridge. A flexible ring is fitted around the side wall of each extrusion plate. Multiple support protrusions are fixedly connected to the inner bottom wall of the receiving groove to limit the descent distance of the extrusion plates.

[0011] To transport the wastewater to be treated, the wastewater supply assembly further includes a water pump and an arc-shaped water conveying cylinder. The water pump is disposed in the bottom tank, and the arc-shaped water conveying cylinder is fixedly connected to the bottom tank. The input end of the water pump is connected to the connecting water cylinder, and the output end of the water pump is connected to the arc-shaped water conveying cylinder. One end of the curved filter core is connected to the arc-shaped water conveying cylinder.

[0012] To further treat the impurities remaining inside the curved filter core, the receiving tank is rotatably connected to the side wall of the bow-shaped water conveying cylinder via a rotating shaft. Slots are provided on both sides of the bottom tank, allowing the receiving tank to move out of the bottom tank through these slots. A drain outlet is located on the side of the curved filter core away from the bow-shaped water conveying cylinder, and a sealing plug is installed inside the drain outlet. Multiple support platforms are fixedly connected inside the bottom tank, and multiple plate-shaped protrusions are provided on the top of each support platform, contacting the inner bottom wall of the receiving tank.

[0013] To collect the dripping water from the transport vehicle, the dripping water collection structure further includes a fixed trough, which is fixedly connected to the top side of the bottom trough. A support frame is provided on the top of the fixed trough, and the inner bottom wall of the fixed trough is also sloped. The lowest point of the inner bottom wall of the fixed trough is connected to the filtered water storage tank.

[0014] To further secure the position of the mounting groove, the bottom groove is provided with multiple hydraulic reset structures for raising and resetting the mounting groove.

[0015] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, when it is necessary to clean the transport vehicle, the transport vehicle can be thoroughly cleaned in the initial cleaning area and the secondary cleaning area. Then, the transport vehicle is driven to the draining area to drain the water remaining on the transport vehicle, thus completing the complete cleaning operation of the transport vehicle. Furthermore, under the action of the initial water collection structure, the cleaning platform and the draining collection structure, the wastewater generated during the cleaning process is collected, which facilitates the recycling of wastewater.

[0016] 2. In this invention, the wastewater collected by the initial water collection structure and the cleaning platform can be treated by the water collection and filtration structure. The treated wastewater is discharged into the filtered water storage tank. When the transport vehicle is cleaned in the future, the filtered water can be used to clean the transport vehicle, reducing the total water consumption. Furthermore, the weight of the transport vehicle forces the cleaning platform to descend, which increases the filtration speed of the wastewater by the water collection and filtration structure.

[0017] 3. In this invention, when there are many impurities retained in the curved filter core, the curved filter core can be removed from the bottom groove to remove the impurities and ensure that the invention can be used for a long time on the construction site. Attached Figure Description

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1 to 8 As shown, the present invention discloses a car washing platform for construction sites, including a cement base 1 and a bottom trough 2 provided inside the cement base 1. The cement base 1 is set in an area of ​​the construction site where water supply is convenient and does not affect construction. The bottom trough 2 is provided inside the cement base 1 for installing various parts of the washing and transport vehicles. It also includes a preliminary cleaning area 3, a secondary cleaning area 4, and a draining area 5. The preliminary cleaning area 3 is located on one side of the bottom tank 2. A preliminary water collection structure 100 is installed within the preliminary cleaning area 3 for the first cleaning of the transport vehicle. The preliminary water collection structure 100 has sand filtering and drainage functions. The preliminary water collection structure 100 includes a water collection trough 8 and a sloping connecting trough frame 10. The water collection trough 8 is fixedly connected to the bottom tank 2. The side of the water collection trough 8 closest to the secondary cleaning area 4 is designated as a drainage area. Multiple drainage outlets 9 are provided within the drainage area. The bottom of the water collection trough 8 is fixedly connected to the sloping connecting trough frame 10, which communicates with the drainage area. When the transport vehicle needs preliminary cleaning, it is driven into the water collection trough 8. The wheels of the transport vehicle are positioned within the water collection tank 8. Since the tires of the transport vehicle carry the most sand, gravel, and cement powder from the construction site, the wheel area of ​​the transport vehicle needs to be cleaned. The wastewater generated during the cleaning process will flow into the water collection tank 8, and then into the sloping connecting trough 10 through the drain outlet 9, and then into the connecting water cylinder 13. Because large sand and gravel particles have a certain weight, when the sand and gravel flow along with the wastewater in the inner bottom wall of the water collection tank 8 and the sloping connecting trough 10, the sand and gravel will remain in the water collection tank 8 and the sloping connecting trough 10. The sand and gravel in the water collection tank 8 and the sloping connecting trough 10 can be cleaned by disassembling the water collection tank 8.

[0027] The middle part of the bottom tank 2 is set as a secondary cleaning area 4. A cover 30 is built on the secondary cleaning area 4. The cover 30 is used to store the flushing equipment for washing the transport vehicle. A cleaning platform 200 that can move longitudinally is set in the secondary cleaning area 4. The cleaning platform 200 includes an installation tank 11 and a squeezing filter assembly. The installation tank 11 slides longitudinally in the middle of the bottom tank 2. A water collection plate 12 is fixedly connected to the top of the installation tank 11. The inner bottom wall of the installation tank 11 is sloped. A squeezing filter assembly that cooperates with the water collection and filtration structure 300 is fixedly connected to the bottom of the installation tank 11. After the initial cleaning operation of the transport vehicle, the transport vehicle is driven to the surface of the water collection plate 12. At this time, the surface of the transport vehicle is thoroughly rinsed, and the flushed wastewater will enter the installation tank 11. A water collection and filtration structure 300 is provided between the preliminary cleaning area 3 and the secondary cleaning area 4. The water collection and filtration structure 300 can collect and filter the sewage generated by the preliminary and secondary cleaning of the transport vehicle. The cleaning platform 200 can improve the filtration speed of the technical filtration structure for sewage by means of the weight of the transport vehicle. The water collection and filtration structure 300 includes a connecting water cylinder 13, a receiving tank 15 and a curved filter core 16. The connecting water cylinder 13 is fixedly connected to the bottom tank 2. The connecting water cylinder 13 passes through the preliminary cleaning area 3 and the secondary cleaning area 4. The sloping connecting tank frame 10 is connected to one side of the connecting water cylinder 13. A telescopic flexible tube 14 is connected between the lowest point of the inner bottom wall of the installation tank 11 and the connecting water cylinder 13. The sewage in the installation tank 11 can enter the connecting water cylinder 13 through the telescopic flexible tube 14, and the telescopic flexible tube 14 can adapt to the height change of the installation tank 11. Two receiving tanks 15 are provided. The receiving tanks 15 are rotatably installed in the bottom tank 2 and can be moved out of the bottom tank 2. The filtered water filtered in the receiving tanks 15 is transported to the filtered water storage tank 6. The bottom of the filtered water storage tank 6 is connected to a receiving tank 17. The receiving tank 17 is located on one side of the bottom of the two receiving tanks 15. The area of ​​the receiving tank 15 above the receiving tank 17 has multiple water outlets. After the filtered water inside the curved filter core 16 flows into the receiving tank 15, it flows directly into the receiving tank 17 through the multiple water outlets, so that the filtered water is stored in the filtered water storage tank 6 in a different direction. Because of the receiving tank 17, the amount of water stored in the filtered water storage tank 6 will not exceed the water storage capacity of the receiving tank 17. A curved filter core 16 is installed inside the receiving tank 15. A squeeze filtration assembly is used to filter the two curved filter cores 16 by pressure. The squeeze filtration assembly includes a squeeze plate 18 and a support protrusion 20. There are two squeeze plates 18, which are located on the upper side of the corresponding curved filter core 16. A flexible ring 19 is sleeved on the side wall of the squeeze plate 18. Multiple support protrusions 20 are fixedly connected to the inner bottom wall of the receiving tank 15 to limit the descent distance of the squeeze plate 18. The wastewater to be treated is transported from the connecting water cylinder 13 to the curved filter core. After the core 16 is filled with sewage, the sewage will be filtered through the mesh on the side wall of the curved filter core 16, and the sewage will become filtered water after passing through the curved filter core 16. Because the sewage filtration speed is relatively slow under its own permeation filtration principle, the present invention can fill the curved filter core 16 with sewage and use the weight of the transport vehicle to drive the installation tank 11 to descend. When the installation tank 11 descends, it drives the extrusion plate 18 and the flexible ring 19 to descend, extruding and deforming the curved filter core 16. Under the action of pressure, the sewage in the curved filter core 16 can be discharged more quickly. A sewage supply assembly is provided between the connecting water cylinder 13 and the two curved filter cores 16. The sewage supply assembly includes a water pump 21 and an arc-shaped water conveying cylinder 22. The water pump 21 is located in the bottom tank 2, and the arc-shaped water conveying cylinder 22 is fixedly connected in the bottom tank 2. The input end of the water pump 21 is connected to the connecting water cylinder 13, and the output end of the water pump 21 is connected to the arc-shaped water conveying cylinder 22. One end of the curved filter core 16 is connected to the arc-shaped water conveying cylinder 22. After the sewage in the sloping connecting frame and the installation tank 11 is discharged into the water pump, the water pump 21 is started to transport the sewage in the water pump to the arc-shaped water conveying cylinder 22, and then the arc-shaped water conveying cylinder 22 discharges the sewage into the two curved filter cores 16. The shape design of the arc-shaped water conveying cylinder 22 is to reduce the sewage conveying area while ensuring sufficient conveying length.

[0028] The receiving tank 15 is rotatably connected to the side wall of the bow-shaped water conveying cylinder 22 via the rotating shaft 23. The bottom tank 2 has slots 24 on both sides. The receiving tank 15 moves out of the bottom tank 2 through the slots 24. When it is necessary to clean the impurities in the curved filter core 16, the receiving tank 15 can be moved along the center point of the rotating shaft 23 to move out of the bottom tank 2 through the slots 24. A sealing plate is provided in the slots 24 to close the slots 24. The side of the curved filter core 16 away from the bow-shaped water conveying cylinder 22 is designated as a drain outlet. A sealing plug 25 is installed inside the drain outlet. The curved filter core 16 can be removed from the bow-shaped water conveying cylinder 22, and the sealing plug 25 can be removed, so that the two ends of the curved filter core 16 remain open, which facilitates the flushing out of impurities inside the curved filter core 16 and the discharge of impurities through the drain outlet. After the sealing plug 25 is inserted into the drain outlet, it blocks the drain outlet, so that sewage can only be discharged through the curved filter core 16. Multiple support platforms 26 are fixedly connected inside the bottom tank 2. Multiple plate-shaped protrusions 27 are provided on the top of the support platforms 26. The plate-shaped protrusions 27 contact the inner bottom wall of the receiving tank 15. The plate-shaped protrusions 27 are used to support the receiving tank 15. During the pressure filtration operation in the curved filter core 16 inside the receiving tank 15, the support platforms 26 effectively support the receiving tank 15. The multiple plate-shaped protrusions 27 can not only ensure effective support for the receiving tank 15, but also prevent the receiving tank 15 from generating large frictional forces when it moves.

[0029] The other side of the top of the bottom tank 2 is set as a drain area 5. The drain area 5 is equipped with a drain collection structure 400 to collect the wastewater generated during the final cleaning of the transport vehicle. The drain collection structure 400 includes a fixed tank 28, which is fixedly connected to the top side of the bottom tank 2. A support frame 29 is set on the top of the fixed tank 28. The inner bottom wall of the fixed tank 28 is also sloped. The lowest point of the inner bottom wall of the fixed tank 28 is connected to the filtered water storage tank 6. After the transport vehicle is cleaned from the canopy 30, the transport vehicle is driven to the top of the support frame 29 so that the residual cleaning water on the surface of the transport vehicle drains into the fixed tank 28. Because the residual water after the transport vehicle is clean is relatively clean, the drain water can be directly discharged into the filtered water storage tank 6.

[0030] The bottom of the drain collection structure 400 is equipped with a filtered water storage tank 6 and a clean water storage tank 7. Both the water collection and filtration structure 300 and the drain collection structure 400 are connected to the filtered water storage tank 6. Both the filtered water storage tank 6 and the clean water storage tank 7 are connected to the outside through a discharge valve pipe 37. The clean water storage tank 7 is also connected to a water injection valve pipe 38 for injecting clean water into the clean water storage tank 7 for storage. Both discharge valve pipes 37 are connected to a flushing device for washing transport vehicles.

[0031] The bottom trough 2 has multiple hydraulic reset structures in the middle for raising and resetting the mounting trough 11. Each hydraulic reset structure includes a mounting cylinder 31, which is fixedly connected to the cement base 1. A hydraulic cylinder 32 is installed inside the mounting cylinder 31. A curved connector 33 is connected to the mounting trough 11. A receiving cylinder 34 is provided at the output end of the hydraulic cylinder 32. A sliding rod 35 is fixedly connected to the top of the curved connector 33, and the sliding rod 35 slides through and is slidably connected to the receiving cylinder 34. A spring damper 36 is provided between the sliding rod 35 and the inner bottom wall of the receiving cylinder 34. An annular abutment seat is provided at the top of the mounting cylinder 31. In the use of this invention, wastewater filtration is only required after the curved filter core 16 is filled with wastewater. First, the hydraulic cylinder 32 drives the curved connector 33 to rise, because the mounting trough... Body 11 will not move out of the bottom tank 2, so the curved connector 33 will stop rising after the mounting tank 11 stops rising, while the output end of the hydraulic cylinder 32 continues to rise, compressing the spring damper 36, so that the mounting tank 11 is fixed at the top of the bottom tank 2. The transport vehicle normally performs cleaning operations at the top of the water collection plate 12. However, when there is too much sewage in the curved filter core 16, before the next transport vehicle cleans it, the hydraulic cylinder 32 is activated to drive the receiving cylinder 34 to descend, so that the bottom of the receiving cylinder 34 contacts the annular abutment seat, keeping the spring damper 36 in an expanded state. Then, after the next transport vehicle drives onto the water collection plate 12, it will drive the mounting tank 11 to descend, the sliding rod 35 moves into the receiving cylinder 34, and the spring damper 36 contracts, thus pressing the curved filter core 16.

[0032] How does this car wash platform at the construction site work? First, the transport vehicle is driven into the water collection tank 8 for cleaning. Then, the wastewater generated during the cleaning process is transported to the connecting water cylinder 13 through the water collection tank 8 and the sloping connecting frame. Next, the transport vehicle is driven onto the water collection orifice plate 12 for cleaning. Based on the amount of wastewater in the curved filter core 16, it is determined whether the transport vehicle needs to be pressure filtered. The wastewater generated by the transport vehicle being cleaned on the water collection orifice plate 12 also enters the connecting water cylinder 13. The wastewater is transported to the two curved filter cores 16 through the conveying water pump 21 and the bow-shaped water conveying cylinder 22. After the curved filter cores 16 filter the wastewater, the filtered water is discharged into the filtered water storage tank 6. Then, the cleaned transport vehicle is driven onto the support trough 29 to drain. The drained water enters the filtered water storage tank 6 through the fixed trough 28. When it is necessary to clean the impurities inside the curved filter core 16, the receiving tank 15 can be moved along the center point of the rotating shaft 23, and the receiving tank 15 can be moved out of the bottom tank 2 through the slot 24. The sealing plug 25 can be removed, so that the two ends of the curved filter core 16 are connected, which makes it easier to flush out the impurities inside the curved filter core 16 and discharge the impurities through the drain port.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
