DETAILED DESCRIPTION

[0025] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0026] The following is combined with Figure 1-Figure 8 This embodiment is described in further detail.

[0027] like Figure 1 As shown, a construction rainwater drainage structure in this embodiment includes a box body 100 and a filter chamber 201 arranged in the box body 100, a water outlet pipe 101 connected to the filter chamber 201 is arranged at the lower end of the box body 100, a water pump 160 for pumping accumulated water into the filter chamber 201 is arranged at the upper end of the box body 100, a slot 301 connected to the filter chamber 201 is arranged on one side wall of the box body 100, a mounting plate 110 is arranged at the slot 301, and a slot 301 is arranged on the mounting plate 110, and a slot 301 is arranged on the mounting plate 110. A filter plate 210 is formed through an opening 301 and extends into the filter cavity 201, a plurality of filter holes are formed on the filter plate 210, a pushing assembly for pushing material into the filter holes is provided on the filter plate 210, a box body 120 is provided on one side wall of the box body 100, a cavity 702 is provided in the box body 120, a disassembly assembly for disassembling and assembling the mounting plate 110 at the slot 301 is provided in the cavity 702, and fixing assemblies for fixing the box body 100 on the ground are provided on opposite side walls of the box body 100.

[0028] In actual use of this embodiment, a water pipe connected to the existing drainage pipe is installed on the water outlet pipe 101, and the accumulated water in the construction site is pumped into the filter chamber 201 through the water pump 160. After the accumulated water in the filter chamber 201 is filtered through the filter holes on the filter plate 210, the silt in the accumulated water will accumulate on the filter plate 210, and the filtered accumulated water will flow into the drainage pipe through the water pipe on the water outlet pipe 101, thereby achieving drainage of the construction site and preventing the silt in the accumulated water from clogging the drainage pipe. Among them, after the accumulated water is filtered through the filter holes, the silt in the accumulated water accumulates on the filter plate 210, so that the filter holes may be blocked by the silt, thereby affecting the filtering of the accumulated water by the filter holes. At this time, the silt on the filter holes is pushed by the pushing component, which can prevent the silt from blocking the filter holes. Compared with the existing ones, this kind of construction rainwater drainage structure can avoid the silt from blocking the filter holes during actual use, thereby affecting the actual use of the filter plate 210. Among them, the filter plate 210 is fixedly installed on the mounting plate 110. After the drainage of the construction site is completed, the mounting plate 110 is released from the notch 301 by disassembling the assembly, so that the mounting plate 110 can drive the filter plate 210 to slide, so that the filter plate 210 in the filter chamber 201 can be pulled out from the notch 301. At this time, the staff can clean the mud and sand on the filter plate 210. After the filter plate 210 is cleaned, the filter plate 210 is inserted into the filter chamber 201 from the notch 301 through the mounting plate 110, and the mounting plate 110 is installed at the notch 301 by disassembling the assembly, so as to realize the installation of the filter plate 210 in the filter chamber 201. When the water pump 160 is working, the water pump 160 will vibrate, so that the box 100 will also vibrate with the vibration of the water pump 160, thereby causing the box 100 to be placed on the ground unstably, and the box 100 is likely to tip over. At this time, the box 100 is fixed on the ground by a fixing assembly, thereby reducing the risk of the box 100 tipping over. A handle 170 is fixedly mounted on the upper end surface of the box 100, and the staff can use the handle 170 to transfer the box 100; In actual use, a lap plate 240 for overlapping the filter plate 210 is fixedly installed in the filter cavity 201. When both ends of the filter plate 210 are overlapped on the corresponding lap plates 240, the installation effect of the filter plate 210 in the filter cavity 201 is better.

[0029] like Figure 1-5 As shown, in this embodiment, the pushing assembly includes a slidable bracket 220 disposed on the filter plate 210, and a plurality of push plates 221 are disposed on the bracket 220. The bracket 220 moves to drive the push plates 221 to push the sediment at the filter holes.

[0030] like Figure 5 As shown, in this embodiment, a plurality of filter holes are evenly arranged along the left and right directions of the filter plate 210. At the same time, a plurality of filter holes are arranged along the front and rear directions of the filter plate 210. The push plate 221 is arranged along the left and right directions of the filter plate 210, and its number matches the plurality of filter holes. In this embodiment, by setting the bracket 220 and the push plate 221, the push plate 221 is fixedly installed on the bracket 220. When the bracket 220 moves, the bracket 220 drives the push plate 221 to move on the filter plate 210, so that the push plate 221 pushes the sediment on the filter hole, so that the sediment is pushed to the filter plate 210 between the adjacent filter holes, thereby preventing the filter hole from being blocked by sediment and affecting the filtering effect of the filter plate 210 on the accumulated water; In actual use, a push rod 400 with one end penetrating the mounting plate 110 is fixedly installed on one side wall of the bracket 220, and a push plate 410 for driving the push rod 400 to move is fixedly installed on the push rod 400. The push plate 410 pushes the push rod 400 to move, and the movement of the push rod 400 can drive the bracket 220 on the filter plate 210 to move, that is, drive the push plate 221 to push the mud and sand on the filter plate 210.

[0031] like Figure 1-6 As shown, in this embodiment, fixed blocks 230 are provided on the filter plate 210 and on both sides of the bracket 220, a fixed cavity 501 is provided in the fixed block 230, a fixed groove 601 is opened on the side wall of the fixed block 230 along the moving direction of the bracket 220, a slidable moving block 610 is provided in the fixed cavity 501, and a connecting block 611 is provided on the moving block 610, one end of which passes through the fixing groove 601 and is connected to the bracket 220, and a first spring 620 for pushing the moving block 610 to move is also provided in the fixed cavity 501.

[0032] In this embodiment, by setting the fixed block 230, the fixed cavity 501, the fixed groove 601, the moving block 610, the connecting block 611 and the first spring 620, the fixed block 230 is fixedly installed on the filter plate 210, and the moving block 610 and the bracket 220 are fixedly connected through the connecting block 611. When the staff drives the push plate 221 on the bracket 220 to push the filter plate 210 through the push plate 410, the bracket 220 moves through the connecting block 611 to drive the moving block 610 to move in the fixed cavity 501. At this time , the moving block 610 squeezes the first spring 620 in the fixed cavity 501. When the staff releases the drive of the push plate 410, the first spring 620 is released from compression, and the first spring 620 pushes the moving block 610 to move. The moving block 610 drives the bracket 220 to move through the connecting block 611, so that the bracket 220 moves to the initial position. Through the above structure, when the staff is actually using it, they only need to repeatedly press the push plate 410 to realize the push plate 221 pushing the filter plate 210 multiple times, thereby facilitating actual use; During actual use, the side wall of the bracket 220 slides and fits with the side wall of the fixing block 230, and the bracket 220 can shield the fixing groove 601, thereby preventing mud and sand in the accumulated water from entering the fixing cavity 501 from the fixing groove 601, thereby affecting actual use.

[0033] like Figure 1-7 As shown, in this embodiment, a connecting groove 701 connecting to the cavity 702 is provided on the lower end surface of the box body 120 along its length direction, and a groove 302 for the mounting plate 110 to abut is provided at the notch 301; The disassembly assembly component includes round rods 710 which are relatively arranged in the cavity 702 and can rotate. The round rods 710 are each provided with a disassembly block 711. The rotation of the round rods 710 is used to drive the side walls of the disassembly block 711 to abut or not abut the mounting plate 110. A rotating part is also provided in the cavity 702 for synchronously driving the two round rods 710 to rotate.

[0034] In this embodiment, by setting the connecting groove 701, the groove 302, the round rod 710, the disassembly block 711 and the rotating member, the disassembly block 711 is fixedly installed on the round rod 710, and the two ends of the round rod 710 are inserted into the side walls of the cavity 702, so that the rotation installation of the round rod 710 is realized. When the mounting plate 110 abuts against the groove 302, when the two round rods 710 are driven to rotate synchronously by the rotating member, the round rod 710 will drive the disassembly block 711 to rotate. When the side wall of the disassembly block 711 extends out of the connecting groove 701 and abuts against the mounting plate 110, the mounting plate 110 is installed at the notch 301. When the rotating member drives the two round rods 710 to rotate synchronously so that the disassembly block 711 on the round rod 710 does not abut against the mounting plate 110, the mounting plate 110 can be released from the notch 301. A handle 111 is fixedly mounted on the mounting plate 110. When the mounting plate 110 is released from the slot 301, the mounting plate 110 can be easily slid out of the slot 301 through the handle 111. In actual use, when a sealing gasket is fixedly installed on the side wall of the mounting plate 110 facing the groove 302 , when the mounting plate 110 is installed at the notch 301 , the mounting plate 110 can seal the notch 301 through the sealing gasket, thereby preventing the accumulated water in the filter chamber 201 from leaking from the notch 301 .

[0035] like Figure 1-8 As shown, in this embodiment, the round rods 710 are sleeved with gears 712, and a clamping block 730 is provided on the upper end surface of the cavity 702 along the direction of the connecting groove 701; The rotating part includes a screw rod 740 which is arranged in the cavity 702 and can rotate. A rack 750 which is threadedly sleeved on the screw rod 740 and meshes with the two gears 712 is provided. The rack 750 is provided with a slot for one end of the block 730 to be inserted into. The rotation of the screw rod 740 is used to drive the rack 750 to move, so that the gear 712 drives the round rod 710 to rotate.

[0036] In this embodiment, by setting the gear 712, the slot, the screw rod 740, the rack 750 and the block 730, the gear 712 is fixedly mounted on the round rod 710, the two ends of the screw rod 740 are rotatably mounted in the cavity 702 through bearings, and the block 730 is fixedly mounted on the upper end surface of the cavity 702. When the screw rod 740 is threadedly rotated, the rack 750 is limited by the block 730, so that the rack 750 moves along the screw rod 740. The movement of the rack 750 drives the two racks 750 to rotate synchronously, that is, the two racks 750 synchronously drive the round rod 710 to rotate; In actual use, one end of the screw rod 740 is extended out of the box body 120, and a handle 720 for driving the screw rod 740 to rotate is fixedly installed on the extended end of the screw rod 740. The handle 720 is convenient for the staff to drive the screw rod 740 to rotate.

[0037] like Figure 1-8 As shown, in this embodiment, the opposite side walls of the box body 100 are provided with vertical plates 130, and two cavities 801 opening downward are provided in the vertical plates 130, and the openings of the cavities 801 are provided with blocking rings 810; The fixing assembly includes a circular plate 820 which is arranged in the cavity 801 and slides. The circular plate 820 is provided with an insertion rod 821 with one end passing through the blocking ring 810. The blocking ring 810 is provided with a second spring 830 for pushing the circular plate 820 away from the blocking ring 810. The vertical plate 130 is also provided with a driving member for synchronously driving the two insertion rods 821 to move downward.

[0038] In this embodiment, by setting the vertical plate 130, the cavity 801, the blocking ring 810, the circular plate 820, the plugging rod 821, the second spring 830 and the driving member, the vertical plate 130 is fixedly installed on the side wall of the box body 100, the plugging rod 821 is fixedly installed on the circular plate 820, the blocking ring 810 is threadedly installed at the opening of the cavity 801, and the second spring 830 and the circular plate 820 are limited in the cavity 801. Before the box body 100 is placed on the ground, the lower ends of the two plugging rods 821 are driven by the driving member to extend out of the cavity 801. At this time, when the box body 100 is placed on the ground, the lower end of the plugging rod 821 is inserted into the ground, so that the box body 100 is fixed on the ground, reducing the risk of the box body 100 tipping over. The lower end of the insertion rod 821 is in a pointed cone shape, so that the insertion rod 821 can be better inserted into the ground; In actual use, when the driving member releases the drive on the insertion rod 821, the second spring 830 will drive the lower end of the insertion rod 821 to retract into the cavity 801, thereby preventing the lower end of the insertion rod 821 from being exposed when the insertion rod 821 is not in use, causing the staff to be stabbed by the exposed insertion rod 821.

[0039] like Figure 1-8 As shown, in this embodiment, the upper end surface of the circular plate 820 is provided with a vertical rod 140 with one end penetrating the vertical plate 130; The driving member includes a driving plate 150 arranged on the vertical plate 130. The upper ends of the two vertical rods 140 are respectively connected to the two end portions of the driving plate 150. The driving plate 150 moves downward to synchronously drive the two vertical rods 140 to move downward, thereby realizing the synchronous downward movement of the two insertion rods 821. The driving plate 150 is also provided with a positioning member for positioning the position of the driving plate 150 after it moves downward.

[0040] In this embodiment, by setting the vertical rod 140 and the driving plate 150, the upper end of the vertical rod 140 is fixedly connected to the driving plate 150. When the staff presses the driving plate 150 to move downward, the driving plate 150 can drive the lower ends of the two insertion rods 821 to extend out of the cavity 801 at the same time through the two vertical rods 140. At this time, the position of the driving plate 150 is positioned by the positioning member, so that the lower ends of the two insertion rods 821 can always remain in a state of extending out of the cavity 801. like Figure 1 As shown, in this embodiment, the positioning member includes a rotatable bolt 151 disposed on the driving plate 150, and the lower end of the bolt 151 is threadedly inserted into the vertical plate 130 to position the driving plate 150 after it moves downward.

[0041] In this embodiment, the bolt 151 is rotatably mounted on the driving plate 150 through the bearing. When the driving plate 150 moves downward, the bolt 151 is rotated so that the lower end thread of the bolt 151 is inserted into the vertical plate 130, so that the position of the driving plate 150 can be positioned. When it is actually used, the positioning of the driving plate 150 can be released by rotating the bolt 151 out from the vertical plate 130 .

[0042] Working principle: First, by pressing the driving plate 150 and inserting the lower end thread of the bolt 151 into the vertical plate 130, the lower end of the plug rod 821 extends out of the cavity 801. Then, the box 100 is placed on the ground, and the lower end of the plug rod 821 is inserted into the ground. At the same time, the water pipe on the outlet pipe 101 is connected to the drainage pipe. At this time, the accumulated water generated by rainfall at the construction site can be pumped into the filter chamber 201 through the pump 160. The accumulated water in the filter chamber 201 is filtered by the filter plate 210 and then discharged into the drainage pipe through the outlet pipe 101. When the filter holes on the filter plate 210 are blocked by sediment, the push plate 410 is driven to The push rod 400 moves, so that the push plate 221 on the bracket 220 pushes the mud on the filter hole, thereby preventing the filter hole from being blocked by the mud. When the water pump 160 completes the pumping of the accumulated water, the screw rod 740 is driven to rotate by turning the handle 720, so that the rack 750 drives the two gears 712 to rotate, and the rotation of the gear 712 drives the round rod 710 to rotate, so that the disassembly block 711 on the round rod 710 releases the contact with the mounting plate 110. At this time, the filter plate 210 can be pulled out of the slot 301 through the handle 111. Finally, the mud accumulated on the filter plate 210 can be cleaned.

[0043] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
