Abstract
Description
Technical Field
[0001] This application relates to the field of building construction drainage technology, and in particular to a building construction site drainage system. Background Technology
[0002] During building construction, dewatering of the corresponding foundation pit is usually required. Currently, dewatering typically involves installing dewatering wells and pumping out the accumulated water from these wells. The water collected in the dewatering wells generally only undergoes a simple filtration process, resulting in a significant amount of silt. When the silt accumulates to a certain level, it needs to be cleaned promptly, which can lead to blockages and damage to the pumps, affecting the efficiency of dewatering at deep construction sites. Summary of the Invention
[0003] To improve precipitation efficiency, this application provides a drainage system for building construction sites.
[0004] This application provides a drainage system for building construction sites, which adopts the following technical solution:
[0005] A drainage system for a building construction site includes a dewatering well and a drainage mechanism. The drainage mechanism includes a water pump and a pumping pipe. A water collection tank is provided at the bottom of the dewatering well. The water collection tank includes a first water collection cylinder and a second water collection cylinder that are connected to each other. The first water collection cylinder is located above the second water collection cylinder. A plurality of first filter holes are provided on the side wall of the first water collection cylinder, and a plurality of second filter holes are provided on the side wall of the second water collection cylinder.
[0006] A sealing ring is slidably disposed in the second water collection cylinder along the vertical direction. The sealing ring is fitted with the inner wall of the second water collection cylinder to seal the second filter hole. A drive assembly is provided in the water collection cylinder to drive the sealing ring to move upward so that the sealing ring disengages from the second filter hole.
[0007] The water collection tank is equipped with a water inlet pipe, and the water pumping pipe is connected to the water inlet pipe.
[0008] By adopting the above technical solution, during precipitation, the water pump starts and drains water out of the precipitation well through the pumping pipe. At the start of pumping, the sealing ring is in a closed state for the second filter hole. During this process, the water enters the collection tank after being filtered through the first filter hole. Because the sediment content is higher closer to the bottom of the precipitation well, it is more prone to clogging. When the water level is higher than the second collection tank, the seal closes the second filter hole, allowing the upper layer of water to enter the collection tank through the first filter hole, effectively reducing the sediment content in the pumped water, preventing clogging, and improving precipitation efficiency. When the water level drops to the second collection tank, the driving component drives the sealing ring upwards a certain distance, opening the second filter hole, allowing water to smoothly pass through the second filter hole into the collection tank, enabling the water pump to continue draining water.
[0009] Optionally, a filter cylinder is provided outside the second water collection cylinder, and a plurality of openings are provided on the side wall of the filter cylinder. A blade is rotatably provided outside the second water collection cylinder to drive the water collected between the filter cylinder and the second water collection cylinder to rotate. A power component is provided inside the water collection cylinder to drive the blade to rotate around the second water collection cylinder. A sand collection box is connected to the bottom of the filter cylinder.
[0010] Optionally, a mudguard is provided between the second water collection cylinder and the filter cylinder. Multiple mudguards are spaced apart along the circumference of the second water collection cylinder. The mudguard is an arc plate, and the blade is located between the mudguard and the second water collection cylinder.
[0011] By adopting the above technical solution, the water in the filter is rotated during the blade rotation process. Under the action of centrifugal force, the large-diameter mud and sand in the water are thrown onto the baffle plate and then automatically settle to the bottom of the filter cylinder, thereby achieving the purpose of separating mud and sand, reducing the amount of mud and sand entering the second water collection cylinder and preventing blockage.
[0012] Optionally, the dewatering well is equipped with a sand-clearing mechanism for transporting sediment to the outside of the dewatering well. The sand-clearing mechanism includes a sand conveying pipe, the input end of which is connected to a sand collection box.
[0013] Optionally, a mounting plate is fixedly provided on the blade, and a cleaning component for cleaning the second filter hole is provided on the mounting plate.
[0014] Optionally, the cleaning component includes a brush plate and brush bristles, the brush plate being fixedly mounted on the mounting plate, the brush bristles being fixedly mounted on the brush plate, and the brush bristles abutting against the second water collection cylinder.
[0015] Optionally, the brush plate can be detachably mounted on the mounting plate.
[0016] Optionally, the power assembly includes a drive shaft, a drive gear, a gear ring, and a power source. The gear ring is sleeved outside the second water collection tank, the mounting plate is fixedly mounted on the gear ring, the drive shaft is rotatably mounted on the water collection tank in a vertical direction, the drive gear is fixedly mounted on the drive shaft and meshes with the gear ring, and the power source is used to drive the drive shaft to rotate.
[0017] Optionally, the power source includes an impeller, a rotating shaft, a first bevel gear, and a second bevel gear. The rotating shaft is rotatably inserted into the water inlet pipe. The impeller is fixedly mounted on the rotating shaft and located inside the water inlet pipe. The first bevel gear is fixedly mounted at the end of the rotating shaft that extends out of the water inlet pipe. The second bevel gear is fixedly mounted on the drive shaft. The first bevel gear meshes with the second bevel gear.
[0018] Optionally, the drive assembly includes a floating component, a drive rope, and a reversing wheel. The reversing wheel is rotatably disposed inside the first water collection tank. The floating component is able to float on the water surface. The drive rope is wound around the reversing wheel, with one end of the drive rope fixedly connected to the floating component and the other end fixedly connected to a sealing ring. The weight of the floating component is greater than the weight of the sealing ring.
[0019] By adopting the above technical solution, when the water level is high, that is, above the second water collection cylinder, the sealing ring is in the state of sealing the second filter hole; when the water level drops to the second water collection cylinder, the floating part descends, pulling the drive rope to move, and the drive rope drives the sealing ring to rise, so that the sealing ring is released from the seal, and the water can pass through the second filter hole.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] During rainfall, the water pump starts and drains water out of the rainwater well through the pumping pipe. At the beginning of pumping, the sealing ring is in a closed state for the second filter hole. During this process, the water enters the collection tank after being filtered through the first filter hole. Because the sediment content is higher closer to the bottom of the rainwater well, it is more prone to clogging. When the water level is higher than the second collection tank, the seal closes the second filter hole, allowing the upper layer of water to enter the collection tank through the first filter hole. This effectively reduces the sediment content in the pumped water, prevents clogging, and improves rainfall efficiency. When the water level drops to the second collection tank, the drive assembly moves the sealing ring upwards a certain distance, opening the second filter hole. Water can then smoothly pass through the second filter hole into the collection tank, allowing the water pump to continue draining water. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0029] This application discloses a drainage system for building construction sites.
[0030] Reference Figure 1 and Figure 2 A drainage system for a building construction site includes a dewatering well 1 and a drainage mechanism 2. The drainage mechanism 2 includes a water pump 21 and a pumping pipe 22. A water collection tank 3 is installed at the bottom of the dewatering well 1. The water collection tank 3 includes a first water collection cylinder 31 and a second water collection cylinder 32 connected to each other. The first water collection cylinder 31 is located above the second water collection cylinder 32. Both the first water collection cylinder 31 and the second water collection cylinder 32 are cylindrical, and the diameter of the first water collection cylinder 31 is larger than that of the second water collection cylinder 32. A water inlet pipe 33 is installed inside the water collection tank 3. The water inlet pipe 33 passes through the top wall of the first water collection cylinder 31 and extends out of the first water collection cylinder 31. The pumping pipe 22 is connected to the water inlet pipe 33. The pumping pipe 22 and the water inlet pipe 33 are detachably connected for easy installation.
[0031] Reference Figure 2The first water collection cylinder 31 has a plurality of first filter holes 311 on its side wall, and the second water collection cylinder 32 has a plurality of second filter holes 321 on its side wall. The second filter holes 321 are arranged in multiple groups at intervals along the vertical direction, and each group of filter holes is arranged in multiple groups at intervals along the circumference of the second water collection cylinder 32.
[0032] Reference Figure 2 and Figure 3 A sealing ring 322 is slidably installed in the second water collection cylinder 32 along the vertical direction. The sealing ring 322 is made of plastic and fits against the inner wall of the second water collection cylinder 32 to seal the second filter hole 321. The width of the sealing ring along the vertical direction is less than the distance between two adjacent sets of second filter holes 321, so that the sealing ring 322 can move upward and release the sealing effect on the second filter hole 321.
[0033] Reference Figure 2 and Figure 3 The water collection tank 3 is equipped with a drive assembly 4 for driving the sealing ring 322 upward to disengage it from the second filter hole 321. The drive assembly 4 includes a floating element 41, a drive rope 42, and a reversing wheel 43. The reversing wheel 43 is rotatably mounted inside the first water collection tank 31. Two support rods 312 are fixedly mounted on the inner wall of the first water collection tank 31, arranged symmetrically along the diameter of the first filter cylinder 5. The reversing wheel 43 is rotatably mounted on the support rods 312. The floating element 41 can float on the water surface. The drive rope 42 is wound around the reversing wheel 43, with one end of the drive rope 42 fixedly connected to the floating element 41 and the other end fixedly connected to the sealing ring 322. The weight of the floating element 41 is greater than the weight of the sealing ring 322. When the floating element 41 floats on the water surface, the drive rope 42 slackens, and the sealing ring 322 descends and seals the second filter hole 321. The floating component 41 is a circular ring structure, made of plastic or a hollow iron ring. The diameter of the floating component 41 is larger than the distance between the two support rods 312. When the water level is high, the floating component 41 floats up until it abuts against the bottom of the support rod 312. At this time, the floating component 41 can no longer float up, the drive rope 42 is loosened, and the sealing ring 322 is in the state of sealing the second filter hole 321.
[0034] Among them, reference Figure 2 and Figure 4 The second water collection cylinder 32 is fitted with a filter cylinder 5. The filter cylinder 5 has several openings 51 on its side wall away from the second water collection cylinder 32. The second water collection cylinder 32 is rotatably equipped with blades 61 for driving the water accumulation between the filter cylinder 5 and the second water collection cylinder 32 to rotate. A mounting plate 6 is fixedly installed on the blades 61 and is arranged in the vertical direction.
[0035] Reference Figure 4 and Figure 5The mounting plate 6 is equipped with a cleaning component 7 for cleaning the second filter hole 321. The cleaning component 7 includes a brush plate 71 and brush bristles 72. The brush plate 71 is fixedly mounted on the mounting plate 6, and the brush bristles 72 are fixedly mounted on the brush plate 71, abutting against the second water collection cylinder 32. The brush plate 71 is detachably mounted on the mounting plate 6, which has a mounting groove 62. An insert block 711 is fixedly mounted on the brush plate 71 and inserted into the mounting groove 62. A bolt 712 passes through the brush plate 71 and is threadedly connected to the mounting plate 6 via the insert block 711.
[0036] Reference Figure 4 The water collection tank 3 is equipped with a power assembly 8 for driving the blades 61 to rotate circumferentially around the second water collection cylinder 32. The power assembly 8 includes a drive shaft 81, a drive gear 82, a gear ring 83, and a power source. The gear ring 83 is rotatably sleeved on the outside of the second water collection cylinder 32, and the mounting plate 6 is fixedly mounted on the gear ring 83. The drive shaft 81 is rotatably mounted on the water collection tank 3 in the vertical direction, and the drive gear 82 is fixedly mounted on the drive shaft 81 and meshes with the gear ring 83.
[0037] Reference Figure 4 The power source drives the drive shaft 81 to rotate. The power source includes an impeller 841, a rotating shaft 842, a first bevel gear 843, and a second bevel gear 844. The rotating shaft 842 rotatably passes through the water inlet pipe 33. The impeller 841 is fixedly mounted on the rotating shaft 842 and located inside the water inlet pipe 33. In this embodiment, the water inlet pipe 33 is provided with an expansion pipe 331, the diameter of which is larger than that of the water inlet pipe 33. The impeller 841 is located inside the expansion pipe 331 to reduce the obstruction of the water flow by the impeller 841. The first bevel gear 843 is fixedly mounted on the end of the rotating shaft 842 that extends out of the water inlet pipe 33. The second bevel gear 844 is fixedly mounted on the drive shaft 81, and the first bevel gear 843 meshes with the second bevel gear 844.
[0038] Reference Figure 2 A mudguard 52 is provided between the second water collection cylinder 32 and the filter cylinder 5. Multiple mudguards 52 are spaced apart along the circumference of the second water collection cylinder 32. In this embodiment, three mudguards 52 are evenly spaced. The mudguard 52 is an arc-shaped plate, and blades 61 are located between the mudguards 52 and the second water collection cylinder 32. During the rotation of the blades 61, the collected water rotates. Under the action of centrifugal force, large-diameter sediment particles in the collected water are thrown onto the mudguards 52 and then automatically settle to the bottom of the filter cylinder 5, achieving the purpose of separating sediment, reducing the amount of sediment entering the second water collection cylinder 32, and preventing clogging.
[0039] Reference Figure 1 and Figure 2In order to effectively collect and clean the sediment at the bottom of the filter cylinder 5, a sand collection box 53 is connected to the bottom of the filter cylinder 5. The sand collection box 53 includes a collection box 531 and a cleaning box 532. The bottom wall of the collection box 531 is inclined, and the settled sediment gradually concentrates into the cleaning box 532 through the collection box 531.
[0040] Reference Figure 1 The dewatering well 1 is equipped with a sand-cleaning mechanism 9 for transporting sediment to the outside of the well. The sand-cleaning mechanism 9 includes a sand-transporting pipe 91, the input end of which is connected to a cleaning box 532. A spiral conveying blade 61 is rotatably mounted inside the sand-transporting pipe 91, and an output pipe 92 is connected to the sand-transporting pipe 91. A drive motor 93 is fixedly mounted at one end of the sand-transporting pipe 91 near the output pipe 92, and the output shaft of the drive motor 93 is fixedly connected to the spiral conveying blade 61. During operation, the drive motor 93 drives the spiral conveying blade 61 to rotate, and the spiral conveying blade 61 transports sediment along the sand-transporting pipe 91 to the output pipe 92, where it is then discharged.
[0041] The implementation principle of this embodiment is as follows: During precipitation, the water pump 21 starts and drains water from the precipitation well 1 through the pumping pipe 22. When pumping begins, the sealing ring 322 is in a closed state for the second filter hole 321. During this process, the water enters the water collection tank 3 after being filtered through the first filter hole 311. Because the closer to the bottom of the precipitation well 1, the higher the silt content, the easier it is to clog. When the water level is higher than the second water collection tank 32, the sealing element closes the second filter hole 321, allowing the upper layer of water to enter the water collection tank 3 through the first filter hole 311, effectively reducing the silt content in the water pumped during this process, preventing clogging, and improving precipitation efficiency. When the water level drops to the second water collection tank 32, the floating element 41 descends, pulling the drive rope 42 to move. The drive rope 42 drives the sealing ring 322 to rise, causing the sealing ring 322 to disengage. At this time, the water can pass through the second filter hole 321, allowing the water pump 21 to continue draining water.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
