Description

Technical Field

[0001] This invention relates to the field of building construction drainage, and more particularly to a drainage device for building construction. Background Technology

[0002] During the construction process, rainy days are inevitable. This rainwater needs to be diverted in a timely manner to reduce the occurrence of rainwater soaking construction materials. Therefore, drainage ditches are arranged in advance at the construction site to divert and discharge rainwater from various locations on the construction site.

[0003] Construction sites contain waste such as mud, concrete fragments, and discarded decorative materials. This waste is easily carried by rainwater into drainage ditches and flows into the city's sewer system. Therefore, filter screens are usually installed at the end of drainage ditches to filter out some of the larger waste.

[0004] In actual discharge processes, waste may partially or completely clog the filter screen, leading to a decrease in drainage efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage device for building construction, which aims to solve the problem that existing filters are easily clogged by waste, resulting in low drainage efficiency.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0050] Combination Figures 1 to 6This invention provides a drainage device for building construction, comprising:

[0051] Water collection tank 1, with a water collection chamber 11 inside, and a water inlet 13 at the upper end of the water collection tank 1 (e.g., Figure 5 As shown), an overflow port 12 is provided on one side of the water collection tank 1;

[0052] The filter component 2 includes a filter box 21 disposed on the inlet 13 and a filter plate 22 disposed on the top of the filter box 21 and having a plurality of first filter holes 23. The filter plate 22 is located below the outlet of the main drainage channel 14.

[0053] The cleaning component includes a first collection box 3 located on one side of the filter box 21, a first push rod 4 slidably connected to the upper side of the filter plate 22, and a drive assembly 5 connected to the first push rod 4 (such as...). Figure 4 As shown, the drive assembly 5 is mounted on the filter box 21 and is used to drive the first push rod 4 to slide toward the first collection box 3.

[0054] Combination Figure 1 , Figure 2 and Figure 3 In this embodiment, the main drainage ditch 14 does not connect directly to the city's sewer system. Instead, a water collection tank 1 is installed between the drainage ditch and the city's sewer system. The water collection tank 1 is placed in a low-lying area of ​​the construction site, or it can be buried underground. The construction site collects rainwater from various small drainage ditches into the main drainage ditch 14. In other words, each small drainage ditch guides rainwater from various locations on the construction site to the main drainage ditch 14, which then discharges the rainwater through an outlet. Since both the filter box 21 and the water collection tank 1 are located below the main drainage ditch 14, the rainwater flowing out of the outlet can be filtered under its own gravity. After filtration by plate 22, the rainwater flows into filter box 21 and collection tank 1. Collection tank 1 is used for physical sedimentation of this rainwater. After sedimentation, this rainwater can be pumped out and reused for building construction to achieve the purpose of water resource recycling. If the rainfall is heavy and a large amount of rainwater flows into collection tank 1, this rainwater will flow out through overflow port 12. If needed and / or desired, overflow port 12 can be connected to the city's sewer system. That is, overflow port 12 can be connected to the city's sewer system through overflow pipe. It should be understood that a one-way valve should be installed on the overflow pipe to prevent backflow of water from the city's sewer system.

[0055] Since rainwater flowing from the construction site to the main drainage ditch 14 may contain some waste, this application includes a filter plate 22 and a cleaning component. The cleaning component is used to clean the waste that falls on the filter plate 22. Specifically, the lower side of the first push rod 4 abuts against the upper side of the filter plate 22, the upper end of the first collection box 3 has an opening, and the periphery of the first collection box 3 is provided with a third filter hole for rainwater entering the first collection box 3 to flow out. During installation, the first collection box 3 can be fixed to one side of the filter box 21 by bolting. In rainy weather, if there is waste that cannot pass through the filter hole on the filter plate 22, the drive component 5 drives the first push rod 4 to slide. The first push rod 4 pushes the waste that falls on the filter plate 22 toward the opening of the first collection box 3, so that this part of the waste is collected, which is beneficial for the later collection and treatment of waste, and reduces the situation where waste blocks the filter plate 22, which would reduce the drainage efficiency.

[0056] Since the filter plate 22 of this application is externally placed in the main drainage ditch 14, the waste on the filter plate 22 can be treated better. At the same time, the cleaning efficiency can be effectively improved by the action of the drive component 5.

[0057] It should be added that the construction drainage device of this application also includes a submersible silt pump 10, which is installed in the water collection tank 1 and connected to the outside through a pipeline. That is, after the rainfall, the sediment such as silt at the bottom of the water collection tank 1 can be discharged by the submersible silt pump 10.

[0058] It should be noted that this application does not specifically limit the length and width of the filter plate 22. The filter plate 22 is set with a corresponding length and width according to the size of the main drainage channel 14, so that the rainwater in the main drainage channel 14 can enter the water collection tank 1 through the filter plate 22. Therefore, it will not be elaborated further.

[0059] Combination Figure 2 , Figure 3 and Figure 4 In one specific embodiment, the filter box 21 has a filter chamber 24 communicating with the water collection chamber 11, and the drive assembly 5 includes:

[0060] The drive box 51 is located directly below the filter plate 22. The drive box 51 is provided with a drive cavity 511, which is used to receive some of the rainwater that flows into the filter cavity 24 after passing through the filter plate 22.

[0061] The first elastic element is installed at the bottom of the filter chamber 24 and connected to the drive box 51, and is used to drive the drive box 51 to move closer to the filter plate 22.

[0062] The first drive block 53 is fixed at one end of the drive box 51. The filter box 21 is vertically provided with a first drive hole 25 that communicates with the filter cavity 24. The first drive block 53 passes through and protrudes from the first drive hole 25.

[0063] The lower end of the first drive rod 54 is rotatably connected to the outside of the filter box 21. One end of the first drive block 53 abuts against one side of the first drive rod 54. The rotation center of the first drive rod 54 coincides with the sliding axis of the first drive block 53. One end of the first push rod 4 is slidably and rotatably disposed at the upper end of the first drive rod 54.

[0064] The second elastic element is connected to the first drive rod 54 and is used to drive the first drive rod 54 to abut against the first drive block 53.

[0065] A drain component is installed inside the filter chamber 24 to drain the rainwater in the drive chamber 511 after the drive box 51 descends to the target position.

[0066] In this embodiment, the drive box 51 has an opening at the top, and the length of the drive box 51 is less than the length of the filter box 21, so that only a portion of the rainwater left through all the first filter holes 23 will flow into the drive box 51. In this way, the number of times the drive box 51 descends can be adjusted. That is to say, by setting the volume of the drive cavity 511, the efficiency of the first push rod 4 in processing the filter plate 22 can be controlled. In this embodiment, the size of the drive cavity 511 is not specifically limited.

[0067] To support the drive box 51, this embodiment includes a first elastic element. This first elastic element has elastic deformation capability; that is, as the amount of rainwater in the drive cavity 511 increases, the first elastic element is compressed, causing the drive box 51 to move from its initial position (near the filter plate 22) to its target position. During the descent of the drive box 51, the first drive block 53 descends along with it. Since the rotation center of the first drive rod 54 coincides with the sliding axis of the first drive block 53 (i.e., the rotation center of the first drive rod 54 is directly below the first drive block 53), and since the second elastic element continuously drives the first drive rod 54 to press against the side of the first drive block 53, the downward movement of the first drive block 53 will drive the first drive rod 54 to rotate. The first drive rod 54 then drives the first push rod 4 to move towards the first collection box 3, thereby pushing the waste. This embodiment utilizes the gravity of water to automatically clean the waste on the filter plate 22 without requiring additional power, achieving the purpose of energy saving and environmental protection.

[0068] As the drive box 51 moves to the target position, which is below the initial position, i.e. the bottom of the clearance hole 63, the rainwater in the drive cavity 511 is discharged due to the presence of the drainage component. As the rainwater in the drive cavity 511 decreases, the first elastic element drives the drive box 51 to reset under its own elastic recovery action. Similarly, the second elastic element also drives the first push rod 4 to reset.

[0069] In this embodiment, a first sliding hole 58 is provided at the upper end of the first drive rod 54. The first sliding hole 58 extends along the length direction of the first drive rod 54. The first push rod 4 is slidably connected to the first sliding rod via a sliding shaft 101. The sliding shaft 101 is cylindrical. With this design, the sliding shaft 101 is slidably connected to the first sliding hole 58 during the rotation of the first drive rod 54, and has a relative rotational connection with the first drive rod 54, so as to achieve the purpose of moving the first push rod 4 along the length direction of the filter plate 22.

[0070] Combination Figure 3 , Figure 4 and Figure 6 In one specific embodiment, a mounting plate 26 is provided inside the filter cavity 24, and the first elastic element is a plurality of first springs 52 arranged at intervals. The lower end of each first spring 52 is fixed to the upper side of the mounting plate 26 and the upper end is fixed to the lower side of the drive box 51.

[0071] In this embodiment, the mounting plate 26 is arranged horizontally, and both ends of the mounting plate 26 can be fixedly connected to the two side walls of the filter chamber 24 by bolting to support the first spring 52. In this embodiment, there are two first springs 52. During manufacturing, the number of first springs 52 can also be other according to actual needs, which will not be elaborated here.

[0072] Combination Figure 4 and Figure 6 In one specific embodiment, a drain seat 6 is vertically fixed inside the drive box 51, a drain cavity 61 is provided inside the drain seat 6, and a plurality of drain holes 62 are provided at intervals on the periphery of the drain seat 6, all of which communicate with the drain cavity 61. A clearance hole 63 is provided on the bottom wall of the drive box 51, which communicates with the drain hole 62. A sealing plate 64 is slidably connected inside the drain cavity 61 to close the clearance hole 63.

[0073] The drain component is a drive pin 56 that is vertically fixed on the upper side of the mounting plate 26. It is used to drive the sealing plate 64 to move upward after the drive box 51 descends to the target position, so as to connect the clearance hole 63 and the drain hole 62.

[0074] In this embodiment, the drain seat 6 is integrally formed on the bottom wall of the drive box 51 to improve the connection stability between the drain seat 6 and the drive box 51. The inner wall of the drain cavity 61 is vertically symmetrically provided with two limiting grooves 65. The two sides of the sealing plate 64 are respectively fixed with limiting blocks 66. The two limiting blocks 66 are respectively embedded in the corresponding limiting grooves 65 to limit the sealing plate 64. In actual use, the sealing plate 64 slides to the bottom of the drain cavity 61 under its own gravity. In rainy weather, rainwater enters the drive cavity 511 and flows into the drain cavity 61 through the drain hole 62. The water will exert a certain pressure on the sealing plate 64, so that the sealing plate 64 seals the relief hole 63. It should be understood that the upper opening of the relief hole 63 can also be provided with a sealing ring gasket for abutting the sealing plate 64.

[0075] In this embodiment, the drive pin 56 can be fixedly connected to the mounting plate 26 by welding to improve the connection stability between the drive pin 56 and the mounting plate 26. After the drive box 51 descends to a certain height, the drive pin 56 will enter the clearance hole 63 and contact the lower side of the sealing plate 64. As the drive box 51 continues to descend, the drive pin 56 drives the sealing plate 64 to move upward, so that the clearance hole 63 communicates with the drain hole 62, thereby allowing the water in the drive cavity 511 to flow downward through the clearance hole 63.

[0076] It should be understood that the rising speed of the drive box 51 can be controlled according to the number and size of the drain holes 62. At the same time, since the height of the drain seat 6 is basically the same as the depth of the drain cavity 61, even if some water in the drain cavity 61 flows out through the relief hole 63, causing the drive box 51 to move upward under the drive of the first spring 52, that is, the sealing plate 64 moves downward from the top of the drain cavity 61, most of the water in the drive cavity 511 can also flow to the relief hole 63 through the drain holes 62 at the bottom of the drain cavity 61.

[0077] Combination Figure 2 , Figure 3 and Figure 4 In one specific embodiment, a second drive rod 57 is rotatably connected to the outside of the filter box 21. The lower end of the second drive rod 57 is rotatably connected to the lower end of the first drive rod 54. The first drive block 53 is located between the first drive rod 54 and the second drive rod 57, and the other end of the first drive block 53 abuts against one side of the second drive rod 57.

[0078] A second collection box 31 is provided on the other side of the filter box 21, and a second push rod 41 is slidably connected to the filter plate 22. One end of the second push rod 41 is slidably and rotatably located at the upper end of the second drive rod 57.

[0079] The second elastic element is a second spring 55 arranged laterally, with its two ends fixed to the opposite side of the first drive rod 54 and the second drive rod 57, respectively.

[0080] In this embodiment, to improve the structural compactness of the drainage device of this application, the drainage device of this application is also provided with a second collection box 31, a second push rod 41, and a second drive rod 57. It should be understood that the first drive rod 54 and the second drive rod 57 have the same structure, the first push rod 4 and the second push rod 41 have the same structure, and the first collection box 3 and the second collection box 31 have the same structure. The second collection box 31 and the first collection box 3 are located on opposite sides of the filter box 21. During the descent of the first drive block 53, the first drive block 53 will simultaneously drive the first drive rod 54 and the second drive rod 57 to rotate in a direction away from each other, so that the first push rod 4 and the second push rod 41 slide in a direction away from each other. That is to say, the waste on the filter plate 22 is divided into two parts, one part of the waste is pushed to the first collection box 3, and the other part of the waste is pushed to the second collection box 31. This is beneficial to improve the cleaning effect, reduce the sliding length of a single push rod, and at the same time, improve the connection stability between the first drive block 53 and the first drive rod 54 and the second drive rod 57.

[0081] Combination Figure 4 , Figure 5 and Figure 6 In one specific embodiment, a water-blocking component is further provided inside the filter chamber 24, the water-blocking component including:

[0082] The water baffle 7 includes a first sub-water baffle 71 and a second sub-water baffle 72 symmetrically arranged. The first sub-water baffle 71 and the second sub-water baffle 72 are rotatably connected to the filter chamber 24 respectively. The drive box 51 is used to drive the upper ends of the first sub-water baffle 71 and the second sub-water baffle 72 to abut against each other after descending to the target position.

[0083] Two third elastic elements are provided. Each third elastic element is connected to the inner wall of the filter chamber 24 and the corresponding sub-baffle 7, respectively, and is used to drive the upper ends of the first sub-baffle 71 and the second sub-baffle 72 away from each other when the drive box 51 is reset.

[0084] In this embodiment, since the upper end of the drive box 51 has an opening, even if the water in the drive cavity 511 is discharged through the drain hole 62 after the drive box 51 descends to the target position, some rainwater flowing in through the filter plate 22 will still flow into the drive cavity 511. In the case of heavy rain, the amount of rainwater entering the drive cavity 511 may be greater than the amount of rainwater discharged from the drive cavity 511, which may cause the drive box 51 to fail to reset, that is, to rise from the target position to the initial position. Therefore, this application is provided with a water-blocking component.

[0085] Specifically, after the drive box 51 descends to a certain position (between the initial position and the target position), it will abut and squeeze the first sub-baffle 71 and the second sub-baffle 72, causing the upper ends of the first sub-baffle 71 and the second sub-baffle 72 to come together, thereby closing the opening of the drive box 51. That is to say, after the drive box 51 descends to the target position, the rainwater falling into the drive cavity 511 will flow to both sides under the obstruction of the baffle 7. Driven by the drive seat, the first sub-baffle 71 and the second sub-baffle 72 can rotate adaptively, which is simple and easy to operate.

[0086] Combination Figure 4 , Figure 5 and Figure 6 In one specific embodiment, the first sub-baffle plate 71 and the second sub-baffle plate 72 have the same structure. The first sub-baffle plate 71 includes a lower contact portion 74 and an upper contact portion 75 connected to each other. The lower contact portion 74 and the upper contact portion 75 have a first included angle 76. The connection between the lower contact portion 74 and the upper contact portion 75 is rotatably connected to the filter chamber 24 through a first rotating shaft 77. The lower contact portion 74 is used to abut against the lower end of the drive box 51 after the drive box 51 descends to the target position.

[0087] The third elastic element is a torsion spring 73 sleeved on the outer periphery of the first rotating shaft 77. One end of the torsion spring 73 is fixed to the upper contact part 75, and the other end is fixed to the inner wall of the filter cavity 24.

[0088] In this embodiment, the upper contact portion 75 and the lower contact portion 74 are integrally formed to improve the structural strength of the first sub-baffle plate 71. The lower contact portion 74 is inclined downward toward the drive box 51, and the upper contact portion 75 is inclined upward toward the drive box 51. With this arrangement, after the drive box 51 contacts the two lower contact portions 74, it can drive the two upper contact portions 75 to move closer to each other and contact each other.

[0089] In this embodiment, torsion springs 73 are respectively provided at both ends of the first rotating shaft 77, thereby reducing the load on a single torsion spring 73 and extending its service life. When the drive box 51 is in the initial position, the torsion spring 73 is in a normal extension and contraction state. When the drive box 51 is in the target position, the torsion spring 73 is in a compression state. That is to say, the torsion spring 73 also supports the drive box 51 in the target position, thereby reducing the load on the first spring 52 and extending its service life. During the process of the drive box 51 moving upward to the initial position, the first sub-baffle 71 is reset under the elastic recovery action of the torsion spring 73.

[0090] Combination Figure 4 and Figure 6In one specific embodiment, two supporting arc surfaces 8 are symmetrically arranged on both sides of the lower end of the drive box 51, and an arc-shaped column 81 is fixed at the free end of the upper contact part 75. The arc-shaped column 81 is used to abut against the corresponding supporting arc surface 8 when the drive box 51 is in the initial position. The projection of the geometric center line of the arc-shaped column 81 in the vertical direction does not fall into the projection area of ​​the drive box 51 in the vertical direction.

[0091] In this embodiment, the arc-shaped column 81 extends along the length of the upper contact portion 75 and is integrally formed on the upper end of the contact portion. It should be understood that since the arc-shaped column 81 initially contacts the supporting arc surface 8, that is, the baffle plate 7 can also support the drive box 51, thereby preventing the drive box 51 from immediately descending as soon as there is rainwater. Since the projection of the geometric center line of the arc-shaped column 81 in the vertical direction does not fall into the projection area of ​​the drive box 51 in the vertical direction, after the drive box 51 collects a certain amount of rainwater, the drive box 51 will squeeze the arc-shaped column 81, causing the arc-shaped column 81 and the upper contact portion 75 to rotate outward, that is, away from the drive box 51, so that the baffle plate 7 will no longer block the descent of the drive box 51.

[0092] It should be noted that this embodiment does not limit the distance between the projection of the geometric center line of the arc-shaped column 81 in the vertical direction and the projection area of ​​the drive box 51 in the vertical direction.

[0093] Combination Figure 2 , Figure 3 and Figure 6 In one specific embodiment, a guide member 9 is provided between the first push rod 4 and the second push rod 41. The guide member 9 includes:

[0094] Connecting seat 91 is vertically fixed to the upper end of filter box 21, and the connecting seat 91 is vertically provided with sliding groove 911;

[0095] The first guide plate 92 has one end rotated and slidably disposed in the slide groove 911 via the second rotating shaft 94, and the other end slidably abuts against the filter plate 22. The first guide plate 92 is provided with a plurality of second filter holes 921.

[0096] The second guide plate 93 is rotatably connected at one end to the second rotating shaft 94 and slides against the filter plate 22 at the other end. The first guide plate 92 is provided with multiple third filter holes.

[0097] When the second rotating shaft 94 slides down to the bottom of the slide groove 911, the first guide plate 92 and the second guide plate 93 have a second included angle 95. The first guide plate 92 and the second guide plate 93 are used to abut against the inner side of the first push rod 4 and the second push rod 41 respectively when the drive box 51 is in the initial position, so that the second rotating shaft 94 slides to the top of the slide groove 911.

[0098] In this embodiment, due to the presence of the first driving block 53, the first driving rod 54 and the second driving rod 57 are arranged in a V-shape, that is, there is a gap between the first push rod 4 and the second push rod 41. If waste is flushed into this gap, it will be unable to be cleaned by the first push rod 4 or the second push rod 41. Therefore, this application provides a guide 9. Specifically, there are two connecting seats 91, which are symmetrically fixed on opposite sides of the filter box 21. The two ends of the second rotating shaft 94 are respectively connected to the sliding grooves 911 on the two connecting seats 91. When the driving box 51 is in the target position, the first guide plate 92 and the second guide plate 93 will not contact the first push rod 4 and the second push rod 41. At this time, the first guide plate 92 and the second guide plate 93 move downward under their own gravity, so that the second rotating shaft 94 is located at the bottom of the sliding groove 911. It should be noted that the second included angle 95 is not equal to 180 degrees at this time. In other words, the waste will fall on the first guide plate 92 and the second guide plate 93.

[0099] As the drive box 51 rises from the target position to the initial position, the first push rod 4 and the second push rod 41 move towards each other. The first push rod 4 pushes the debris between itself and the first guide rod onto the first guide plate 92, and similarly, the second push rod 41 pushes the debris between itself and the second guide rod onto the second guide plate 93. As the first push rod 4 and the second push rod 41 continue to approach each other, the inner side of the first push rod 4 abuts against the first guide plate 92 and the inner side of the second push rod 41 abuts against the second guide plate 93, thereby driving the first guide plate 92 to move closer to the first guide plate 93. 2. The lower ends of the first guide plate 92 and the second guide plate 93 move closer to each other, that is, the second rotating shaft 94 slides to the top of the slide groove 911, so that the second included angle 95 between the first guide plate 92 and the second guide plate 93 becomes smaller. In other words, the waste on the first guide plate 92 will be guided to the upper side of the first push rod 4, and the waste on the second guide plate 93 will be guided to the upper side of the second push rod 41. More preferably, the upper side of the first push rod 4 and the second push rod 41 is provided with a guide slope 42 for guiding the waste falling into the first push rod 4 or the second push rod 41.

[0100] In one specific embodiment, the filter box 21 is rotatably connected to a third drive rod and a fourth drive rod on the side opposite to the first drive rod 54. The third drive rod is symmetrically arranged with the first drive rod 54, and the fourth drive rod is symmetrically arranged with the second drive rod 57. The other end of the first push rod 4 is slidably and rotatably arranged on the third drive rod, and the other end of the second push rod 41 is slidably and rotatably arranged on the fourth drive rod. A fourth elastic element is provided between the third drive rod and the fourth drive rod.

[0101] The filter box 21 is vertically provided with a second drive hole that communicates with the filter chamber 24. The other end of the drive box 51 is provided with a second drive block. The second drive block passes through and protrudes from the second drive hole. The two ends of the second drive block are respectively used to abut against the opposite sides of the third drive rod and the fourth drive rod.

[0102] In this embodiment, to improve the movement stability of the first push rod 4 and the second push rod 41, a third drive rod, a fourth drive rod, a second drive block, and a fourth elastic element are provided. For ease of understanding, the third drive rod and the first drive rod 54 have the same structure, the fourth drive rod and the second drive rod 57 have the same structure, and the fourth elastic element and the first elastic element have the same structure. Therefore, this embodiment will not describe them again.

[0103] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
