Description

Technical Field

[0002] This invention relates to the field of drainage device technology, and more particularly to a drainage device for building construction. Background Technology

[0004] In construction engineering, the wastewater from foundation pit dewatering, pile foundation construction, site water drainage, and concrete curing must be filtered and treated through drainage devices to remove solid waste containing large amounts of mud, gravel, concrete residue, and construction debris, and then discharged or recycled after meeting the standards.

[0005] In existing technologies, filter canisters with filter holes are typically used as filtration units to achieve solid-liquid separation by trapping solid impurities. However, construction wastewater often contains solid particles with a wide range of sizes, high hardness, and high concentrations, making them prone to embedding in the filter holes and causing blockages. This leads to a sharp reduction in the filter canister's permeable area and a significant decrease in drainage flow. To restore filtration performance, regular maintenance of the filter canister is necessary.

[0006] Hydraulic backwashing is a common cleaning method for filter canisters. It involves spraying high-pressure water from below the filter canister in the opposite direction, using the impact force of the water flow to flush out particles from the filter holes, and then collecting the waste inside the filter plates. However, backwashing requires interrupting the normal filtration process before all filter holes are cleaned, disrupting drainage continuity and significantly reducing drainage efficiency. Summary of the Invention

[0008] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0009] Therefore, the purpose of this invention is to provide a drainage device for construction engineering that can automatically clear the filter holes without stopping the machine, thus maintaining the continuity of drainage operations.

[0015] In one embodiment of the present invention, the actuator includes: a housing, a drive shaft, a forward-rotating water wheel, a reverse-rotating water wheel, a first gearbox, a plurality of arc-shaped electromagnets, a second gearbox, and a water spray assembly. The lower part of the housing is connected to a drainage channel. The drive shaft is rotatably mounted on the housing. One end of the drive shaft is connected to the input end of the first gearbox, and the output end of the first gearbox is connected to the input end of a single-stage bevel gear transmission box. The other end of the drive shaft has a groove. The plurality of arc-shaped electromagnets are respectively connected to the groove via a plurality of fourth spring posts.

The forward-rotating water wheel and the reverse-rotating water wheel are respectively mounted on the drive shaft. The water spray assembly is connected to the housing and is used to drive the forward-rotating water wheel to rotate forward or the reverse-rotating water wheel to rotate backward by spraying water.

[0016] In one embodiment of the present invention, the water spray assembly includes: a pump body, a water guide pipe, a three-way valve, a first nozzle, and a second nozzle. The inlet of the pump body is connected to a water tank, and the outlet of the pump body is connected to the inlet of the three-way valve through the water guide pipe.

[0020] The beneficial effects of this invention are:

[0021] During the normal filtration stage, the filter cake is continuously scraped and broken by a scraper to prevent particles from becoming deeply embedded in the filter pores. When the recovery component is connected to the filter canister, the waste in the filter canister is pushed into the recovery component.

[0022] During the cleaning phase, the entire filter hole cleaning process is automatically completed simply by driving the moving plate to move upwards. The moving plate moves vertically upwards, driving multiple sets of fan-shaped plates to rise synchronously via the second and first spring columns, which maintain their natural extension. This allows the plugs to be inserted into the filter holes, dislodging deeply embedded hard particles, cement lumps, and other blockages. Then, utilizing the structural feature of multiple ropes of varying lengths, after the abutment plate and mounting plate come into contact, the moving plate continues to move upwards, pulling the ropes. After being redirected by the guide components, the corresponding first spring columns are sequentially compressed, causing the plugs to separate and release water from the filter holes in batches. This effectively removes deep-seated hard blockages from the filter holes while enabling continuous drainage without interrupting filtration during the cleaning process. This significantly improves drainage efficiency and construction reliability.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The following describes a drainage device for building construction according to an embodiment of the present invention with reference to the accompanying drawings.

[0042] Drainage device for building construction in embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, it may include: filter bucket 1, water tank 3, cleaning device 5, drive assembly 15 and recycling assembly 16.

[0043] A scraper assembly 2 is rotatably mounted on the filter barrel 1. A water tank 3 is located below the filter barrel 1 and a backing plate 4 is mounted on the water tank 3. The cleaning device 5 includes a movable plate 6, a spring column assembly 7, a mounting plate 8, and multiple fan ring plates 10. The movable plate 6 is connected to the mounting plate 8 through the spring column assembly 7. The fan ring plates 10 are connected to the mounting plate 8 through multiple connectors 9. Multiple plugs 11 are mounted on the upper part of the fan ring plates 10. The plugs 11 are detachably connected to the filter holes on the filter barrel 1. The mounting plate 8 is in contact with the backing plate 4.

[0044] The connector 9 includes a first spring post 12, a rope 13, and a guide 14. The guide 14 is located at the lower part of the mounting plate 8. The fan ring plate 10 is connected to the mounting plate 8 through the first spring post 12. One end of the rope 13 is connected to the moving plate 6, and the other end of the rope 13 is connected to the first spring post 12 after being guided by the guide 14. The lengths of the multiple ropes 13 are different.

[0045] Furthermore, the first spring post 12 includes: a cylinder 17, a movable post 18, and an elastic element 19 (e.g., a spring), wherein the elastic element 19 is disposed inside the cylinder 17, the movable post 18 is slidably connected to the cylinder 17, one end of the movable post 18 is connected to the elastic element 19, and the other end of the movable post 18 is connected to the lower part of the fan ring plate 10, wherein a through hole is provided in the lower part of the cylinder 17, and the rope 13 is connected to the lower part of the movable post 18 through the through hole.

[0046] like Figure 2 and Figure 5 As shown, the water tank 3 is a circular box, and a conical water guide plate 65 is provided between the water tank 3 and the filter barrel 1. The conical water guide plate 65 is fixedly installed on the cylinder 17 (multiple cylinders 17 pass through the conical water guide plate 65, and the conical water guide plate 65 is welded to the outer wall of multiple cylinders 17).

[0047] The conical water guide plate 65 is connected to a frame plate via a support rod. The frame plate is cross-shaped and has multiple limiting grooves (e.g., T-shaped grooves). The side wall of the fan ring plate 10 is provided with multiple limiting sliders. The number of upper limiting grooves on the frame plate is the sum of the number of upper limiting sliders on the multiple fan ring plates 10. Therefore, the multiple limiting sliders correspond one-to-one with the multiple limiting grooves, and the limiting sliders and limiting grooves are slidably connected.

[0048] The drive assembly 15 is connected to the scraper assembly 2 and the moving plate 6 respectively. The drive assembly 15 is configured to drive the scraper assembly 2 to rotate and selectively drive the moving plate 6 to move vertically. After the moving plate 6 is driven by the spring column assembly 7 to abut the mounting plate 8 against the abutment plate 4, it simultaneously pulls multiple ropes 13, causing multiple fan-shaped plates 10 to separate from the filter barrel 1 in sequence. The recycling assembly 16 is detachably connected to the filter barrel 1 and is used to recycle the waste pushed by the scraper assembly 2 inside the filter barrel 1.

[0049] To clearly illustrate the previous embodiment, in one embodiment of the present invention, as follows: Figure 4 , Figure 6 and Figure 7 As shown, the guide component 14 may include: a mounting chamber 22, a connecting column 23, a guide wheel 24, a pressure wheel 25, and a third spring column 26. The mounting chamber 22 has a rope inlet hole and a rope outlet hole. The mounting chamber 22 is connected to the mounting plate 8 through the connecting column 23. The guide wheel 24 is rotatably disposed in the mounting chamber 22. The third spring column 26 is disposed in the mounting chamber 22. The pressure wheel 25 is disposed at the telescopic end of the third spring column 26. The rope 13 abuts against the pressure wheel 25 and the guide wheel 24 respectively. The third spring column 26 has the same structure as the first spring column 12.

[0050] It should be noted that the spring column assembly 7 described in the above embodiments may include: a plurality of second spring columns 20, the movable plate 6 being connected to the mounting plate 8 through the plurality of second spring columns 20, and the second spring columns 20, the third spring columns 26 having the same structure as the first spring column 12.

[0051] It should be noted that the connecting column 23 rigidly fixes the mounting chamber 22 to the lower part of the mounting plate 8, ensuring that the guide member 14 and the mounting plate 8 rise and fall completely synchronously. The rope inlet and outlet holes in the mounting chamber 22 serve as limiting and guiding holes for the rope 13. The guide wheel 24, through the steering characteristics of the fixed pulley, can realize the conversion of the pulling force direction without changing the direction of motion of the drive source (that is, converting the vertical upward pulling force of the rope 13 into the downward pulling force along the axial direction of the first spring column 12). This allows the rope 13 to be pulled vertically to compress the first spring column 12 downward. The groove of the guide wheel 24 matches the diameter of the rope 13, and the third spring column 26 is always in a pre-compressed state. The pressure wheel 25 continuously presses the rope 13 into the groove of the guide wheel 24.

[0052] In one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the drive assembly 15 may include: a driver 27, a single-stage bevel gear transmission box 28, a synchronous toothed belt transmission mechanism 29, a multi-stage bevel gear transmission box 30, and a lead screw linear module 31. The input end of the single-stage bevel gear transmission box 28 is connected to the drive end of the driver 27, and the output end of the single-stage bevel gear transmission box 28 is connected to the scraper assembly 2 through the synchronous toothed belt transmission mechanism 29. The input end of the multi-stage bevel gear transmission box 30 is connected to the drive end of the driver 27, and the output end of the multi-stage bevel gear transmission box 30 is connected to the lead screw linear module 31.

[0053] It is understood that the single-stage bevel gear transmission box 28 described in this embodiment includes: a box body and two second bevel gears, which are respectively mounted on the box body by bearings and mesh with each other.

[0054] The synchronous toothed belt drive mechanism 29 may include a first gear, a second gear, and a toothed belt. The first gear is disposed at the output end of a second bevel gear, the second gear is disposed on the scraper assembly 2, the first gear and the second gear are connected by the toothed belt, and the first gear and the second gear respectively mesh with the toothed belt.

[0055] To clearly illustrate the previous embodiment, in one embodiment of the present invention, as follows: Figure 2 , Figure 8 and Figure 10 As shown, in one possible scenario, the actuator 27 may include: a housing 32, a drive shaft 33, a forward-rotating water wheel 34, a reverse-rotating water wheel 35, a first gearbox 36, multiple arc-shaped electromagnets 37, a second gearbox 38, and a water spray assembly 39. A drainage channel 55 is connected to the lower part of the housing 32. The drive shaft 33 is rotatably mounted on the housing 32, with one end connected to the input end of the first gearbox 36. The output end of the first gearbox 36 is connected to the input end of a single-stage bevel gear transmission 28 (another single-stage bevel gear transmission 28...). The drive shaft 33 is connected to a second gearbox 36 (with two bevel gears). A groove is provided at the other end of the drive shaft 33. Multiple arc-shaped electromagnets 37 are connected to the groove via multiple fourth spring pillars 56 (e.g., springs). The arc-shaped electromagnets 37 abut against the input end of the second gearbox 38 and are magnetically connected to the input end of the second gearbox 38. A forward-rotating water wheel 34 and a reverse-rotating water wheel 35 are respectively mounted on the drive shaft 33. A water spray assembly 39 is connected to the housing 32 and is used to drive the forward-rotating water wheel 34 to rotate forward or the reverse-rotating water wheel 35 to rotate backward via water jets. It should be noted that both the forward-rotating water wheel 34 and the reverse-rotating water wheel 35 are bucket-type water wheels. The input shaft of the second gearbox 38 is coaxially arranged with the drive shaft 33. It should be noted that the first gearbox 36 and the second gearbox 38 are electronically controlled power shift gearboxes.

[0056] like Figure 9 As shown, multiple arc-shaped electromagnets 37 can also be connected to the groove through multiple first electric telescopic rods 66, with the arc-shaped electromagnets 37 located at the drive end of the first electric telescopic rods 66.

[0057] It should be noted that the fourth spring post 56 described in this embodiment (the fourth spring post 56 has the same structure as the first spring post 12) can push the arc-shaped electromagnet 37 to abut against the input end of the second gearbox 38. When the arc-shaped electromagnet 37 is not connected to the input end of the second gearbox 38, the rotation of the forward-rotating waterwheel 34 or the reverse-rotating waterwheel 35 only provides driving force for the first gearbox 36. When the arc-shaped electromagnet 37 is connected to the input end of the second gearbox 38, the rotation of the forward-rotating waterwheel 34 or the reverse-rotating waterwheel 35 provides driving force for both the first gearbox 36 and the second gearbox 38.

[0058] In one embodiment of the present invention, such as Figure 2As shown, the water spray assembly 39 may include: a pump body 40 (electric booster pump), a water guide pipe 41, a three-way valve 42, a first nozzle 43, and a second nozzle 44. The inlet of the pump body 40 is connected to the water tank 3, and the outlet of the pump body 40 is connected to the inlet of the three-way valve 42 through the water guide pipe 41. One end of the first nozzle 43 is connected to one outlet of the three-way valve 42, and the other end of the first nozzle 43 points to the forward-rotating water wheel 34. One end of the second nozzle 44 is connected to the other outlet of the three-way valve 42, and the other end of the second nozzle 44 points to the reverse-rotating water wheel 35.

[0059] It is understood that the pump body 40 described in this embodiment can draw water filtered in the water tank 3 and select the desired first nozzle 43 or second nozzle 44 through the three-way valve 42 (solenoid valve). When the first nozzle 43 sprays water, it drives the drive shaft 33 to rotate forward through the forward rotating water wheel 34. When the second nozzle 44 sprays water, it drives the drive shaft 33 to rotate in reverse through the reverse rotating water wheel 35.

[0060] Furthermore, the linear screw module 31 may include: a rotating shaft 45, a main body housing 46, a first bevel gear set 47, a ball screw pair 48, and a support frame 49. The ball screw pair 48 is disposed inside the main body housing 46. One end of the rotating shaft 45 is connected to the output end of the multi-stage bevel gear transmission box 30, and the other end of the rotating shaft 45 is connected to the ball screw pair 48 through the first bevel gear set 47. The ball screw pair 48 is connected to the movable plate 6 through the support frame 49.

[0061] It is understood that the ball screw assembly 48 described in this embodiment may include: a ball screw and a ball slider. The ball screw is rotatably mounted in the main body housing 46 via a bearing. The ball slider is mounted on the ball screw. The support frame 49 is mounted on the ball slider. The first bevel gear set 47 consists of two meshing first bevel gears. The two first bevel gears mesh with each other. One first bevel gear is mounted on the ball screw, and the other first bevel gear is mounted on the rotating shaft 45.

[0062] The multi-stage bevel gear transmission 30 includes: a drive compartment, a third bevel gear set, a drive shaft, and a fourth bevel gear set. The drive shaft is rotatably mounted in the drive compartment. The third and fourth bevel gear sets are respectively mounted on the drive shaft. The input end of the third bevel gear set is connected to the second gearbox 38 (the third bevel gear set includes two third bevel gears, one of which is connected to the output end of the second gearbox 38, and the other is mounted on the drive shaft, with the two third bevel gears meshing with each other). The output end of the fourth bevel gear set is connected to the rotating shaft 45 (the fourth bevel gear set includes two fourth bevel gears, one of which is connected to the rotating shaft 45, and the other is mounted on the drive shaft, with the two fourth bevel gears meshing with each other).

[0063] In one embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the movable plate 6 has an installation slot, in which multiple spring winding mechanisms 21 are installed. The number of spring winding mechanisms 21 is equal to the total number of connectors 9. Each connector 9 corresponds to one spring winding mechanism 21, and the rope 13 is wound around the spring winding mechanism 21. It should be noted that the spring winding mechanism 21 can also be replaced by a constant force spring winding device or an electric winding wheel.

[0064] Specifically, wastewater generated during construction flows by gravity or is pumped into the filter tank 1, where solid-liquid separation is achieved through evenly distributed filter holes at the bottom of the filter tank 1. Waste particles larger than the filter hole diameter are trapped inside the filter tank 1.

[0065] When the scraper assembly 2 needs to continuously push the waste along the inner wall of the filter barrel 1, the arc-shaped electromagnet 37 is de-energized and demagnetized, maintaining contact with the input end of the second gearbox 38 but without power transmission. The electric booster pump draws filtered clean water from the water tank 3 and delivers it to the three-way valve 42 through the water guide pipe 41. The three-way valve 42 switches to the first nozzle 43 passage, and the high-pressure water jet is sprayed into the water bucket of the forward-rotating water wheel 34, driving the drive shaft 33 to rotate forward. After the power is reduced and increased in torque by the first gearbox 36, it is transmitted to the single-stage bevel gear transmission box 28, and then drives the scraper assembly 2 to rotate through the synchronous toothed belt transmission mechanism 29. The scraper assembly 2 continuously rotates and scrapes the filter barrel 1, and the continuously rotating scraper assembly 2 can continuously break the filter cake formation process and evenly distribute the waste residue, avoiding local overload clogging. The filtered clean water is guided and collected by the conical water guide plate 65 and flows into the annular water tank 3 below for storage.

[0066] When the filter holes need to be cleaned, the three-way valve 42 switches to the second nozzle 44 passage, and the high-pressure water jet is sprayed into the water bucket of the reverse water wheel 35, driving the drive shaft 33 to reverse. At the same time, the arc-shaped electromagnet 37 is energized to generate electromagnetic attraction, which magnetically connects with the input end of the second gearbox 38. Power is simultaneously output to the first gearbox 36 and the second gearbox 38 to achieve synchronous transmission of the two branches.

[0067] The first gearbox 36 continues to drive the scraper assembly 2 to rotate, continuously scraping the filter barrel 1. The second gearbox 38 outputs power to the multi-stage bevel gear transmission box 30, which, after being transmitted through the third bevel gear set, drive shaft, and fourth bevel gear set, drives the rotating shaft 45 to rotate. The rotating shaft 45 drives the ball screw of the ball screw pair 48 to rotate through the first bevel gear set 47, causing the ball slider to move vertically upward along the ball screw, and then driving the moving plate 6 to move vertically upward through the support frame 49.

[0068] During the upward movement of the moving plate 6, the second spring column 20 first drives the mounting plate 8 to move vertically in sync. The mounting plate 8 then drives all the fan ring plates 10 to rise synchronously via the first spring column 12, so that all the plugs 11 on the fan ring plates 10 are inserted into the filter holes at the bottom of the filter barrel 1. During this stage, both the first spring column 12 and the second spring column 20 are in a naturally extended state, ensuring that the fan ring plates 10 rise stably (the elastic force of the first spring column 12 and the second spring column 20 during this stage is greater than the pressure they are subjected to, and the deformation is very small).

[0069] After the plunger 11 is fully inserted into the filter hole and the mounting plate 8 and the abutment plate 4 are rigidly in contact, the mounting plate 8, the guide member 14 fixed thereon, and the first spring column 12 all stop moving upward. However, the linear screw module 31 continues to drive the moving plate 6 to move vertically upward, and the distance between the moving plate 6 and the mounting plate 8 begins to decrease, compressing the second spring column 20. Meanwhile, the rope 13, guided by the guide wheel 24, is continuously pulled by the moving plate 6. When the tension exceeds the pre-tightening force of the elastic element 19 inside the first spring column 12, it begins to pull the moving column 18 of the first spring column 12 to slide downward along the cylinder 17, compressing the internal elastic element 19. As the moving column 18 slides downward, it drives the fan ring plate 10, which is fixedly connected to its upper end, to move downward synchronously, causing the plunger 11 on the fan ring plate 10 to be pulled out of the filter hole of the filter barrel 1, thus separating the fan ring plate 10 from the filter barrel 1.

[0070] Since the multiple ropes 13 are of different lengths, the plugs 11 separate sequentially in order of the shortest rope 13, and the fan ring plate 10 that separates earlier continues to move downwards. During the sequential separation of the plugs 11, the continuously rotating scraper assembly 2 pushes the ejected waste into the recycling assembly 16. Subsequently, the arc electromagnet 37 is de-energized and demagnetized, cutting off the power to the second branch. The three-way valve 42 switches back to the first nozzle 43 passage, driving the drive shaft 33 to rotate forward, causing the lead screw linear module 31 to move in the reverse direction, driving the moving plate 6 to reset downwards, and the first spring column 12 and spring column assembly 7 to reset, thus ending the cleaning process.

[0071] A vision sensor is installed above filter canister 1. Based on the monitoring data from the vision sensor, filter pore cleaning is initiated. Filter canister 1 can also be cleaned periodically.

[0072] As another possible scenario, such as Figure 12 As shown, the driver 27 may include: a first drive motor 70, a second drive motor 71, a first gearbox 36 and a second gearbox 38. The drive end of the first drive motor 70 is connected to the input end of the first gearbox 36, the output end of the first gearbox 36 is connected to the input end of the single-stage bevel gear transmission box 28, and the drive end of the second drive motor 71 is connected to the input end of the second gearbox 38.

[0073] Understandably, the housing 32, drive shaft 33, forward-rotating water wheel 34, reverse-rotating water wheel 35, multiple arc-shaped electromagnets 37 and water spray assembly 39 on the driver 27 in the drive assembly 15 are replaced by a first drive motor 70, which can replace the water wheel drive structure to provide driving force for the first gearbox 36 and the second gearbox 38.

[0074] In one embodiment of the present invention, such as Figure 2 As shown, the scraper assembly 2 may include a mounting post 50 and a blade body 51. The mounting post 50 is rotatably mounted on the filter barrel 1, and the blade body 51 is mounted on the mounting post 50. It should be noted that the mounting post 50 is connected to the synchronous toothed belt drive mechanism 29 (second gear).

The horizontal drive device 52 is located above the filter barrel 1, and the hydraulic lift 53 is located on the drive end of the horizontal drive device 52. The recycling bin 54 is a bin with an opening on the side, and multiple filter holes are provided at the bottom of the recycling bin 54. The recycling bin 54 is located on the drive end of the hydraulic lift 53, and the lower part of the recycling bin 54 is detachably connected to the lower inner wall of the filter barrel 1. The first electromagnet 57 is installed on the inner wall of the recycling bin 54, the push plate 58 is installed inside the recycling bin 54 and is magnetically connected to the first electromagnet 57, the side wall of the recycling bin 54 is provided with a sliding groove, the push plate 58 is slidably connected to the sliding groove, the storage box 59 is installed below the horizontal drive device 52, the motor 60 is installed inside the storage box 59, the electric push rod 61 is installed on the drive end of the motor 60, the second electromagnet 62 is installed on the drive end of the electric push rod 61 and is magnetically connected to the push plate 58.

The horizontal drive device 52 can control the horizontal movement of the recycling bin 54, and the hydraulic lift 53 controls the vertical movement of the recycling bin 54.

[0079] After recycling, the recycling bin 54 is controlled to enter the storage box 59. The electric push rod 61 drives the second electromagnet 62 to abut against the push plate 58. When the second electromagnet 62 is magnetically connected to the push plate 58, the first electromagnet 57 is controlled to lose its magnetism, so that the motor 60 can drive the push plate 58 to move in the recycling bin 54 through the electric push rod 61 and the second electromagnet 62, pushing the waste into the storage box 59.

[0080] Furthermore, the push plate 58 includes a main plate 63 and a sliding plate 64. The sliding plate 64 is slidably connected to the chute and magnetically connected to the first electromagnet 57. The main plate 63 is slidably disposed in the recycling bin 54. The motor 60 can drive the sliding plate 64 to move through the electric push rod 61 and the second electromagnet 62, so that the main plate 63 pushes the waste in the recycling bin 54 into the storage box 59. The connecting rod 69 is also slidably connected to the chute. A conveyor belt assembly can be provided in the storage box 59. The conveyor belt assembly is used to convey the waste pushed out from the recycling bin 54.
