Description

Technical Field

[0001] The present application relates to the technical field of basement construction, and in particular to a basement waterproof structure. Background Art

[0002] A basement is a building below the outdoor ground, mainly used to store vehicles, sundries, or as a civil air defense project. The down ramp of the basement entrance is the main passage connecting the basement to the outside world. Good waterproofing is an important part of the architectural design of the down ramp entrance.

[0003] In the prior art, a drainage ditch for collecting rainwater is provided at the bottom of the slope down the basement, and a filter grating for intercepting foreign matter is installed at the opening of the drainage ditch. The drainage ditch is connected to a drainage pipe, through which the rainwater collected in the drainage ditch is led outward, thereby reducing the possibility of rainwater directly flowing into the basement and causing flooding of the basement.

[0004] However, although the filter grating can reduce the amount of foreign matter falling into the gutter to a certain extent, it is not effective in intercepting soft foreign matter such as plastic bags. In addition, in actual applications, due to repeated pressure from vehicles on the filter grating, the filter grating is very likely to jump out of the gutter. Over time, there is a possibility that the drainage pipeline will be blocked, which reduces the drainage capacity of the gutter. When it rains heavily, the drainage capacity of the gutter is insufficient to drain water quickly, which leads to flooding in the basement. Therefore, further improvement is needed. Summary of the invention

[0005] In order to maintain good drainage performance of the drainage ditch and reduce the possibility of flooding in the basement, the present application provides a basement waterproof structure.

[0006] The basement waterproof structure provided in this application adopts the following technical solutions: A basement waterproof structure comprises a drainage ditch, a filter grating and a drainage pipe, wherein the filter grating is arranged at the opening of the drainage ditch, and one end of the drainage pipe is connected to the drainage ditch for discharging rainwater outward; a spare cavity is provided at the bottom of the drainage ditch, and the spare cavity is connected to the spare pipe for discharging rainwater outward; a first connecting groove connected to the spare cavity is provided on the bottom wall of the drainage ditch, and a cover plate for opening and closing the first connecting groove is hinged in the drainage ditch, and the cover plate is normally closed in the first connecting groove; a buoyancy member is provided between the drainage ditch and the cover plate, and when the rainwater liquid level in the drainage ditch rises to the opening of the drainage ditch, the buoyancy member drives the cover plate to flip to open the first connecting groove.

[0007] By adopting the above technical solution and setting up the spare cavity and the spare pipe, under normal conditions, the cover plate is closed to the first connecting groove, so that rainwater in the drainage ditch is discharged outwardly through the drainage pipe; when foreign objects fall into the drainage ditch and cause the drainage pipe to be blocked, a large amount of rainwater gathers in the drainage ditch and cannot be discharged in time, causing the rainwater level in the drainage ditch to continue to rise. When the rainwater level in the drainage ditch rises to the opening of the drainage ditch, the buoyancy member drives the cover plate to flip over to open the first connecting groove, and the rainwater in the drainage ditch can be discharged outwardly through the spare pipe, so that the drainage ditch maintains good drainage performance and reduces the possibility of basement flooding.

[0008] Optionally, a first torsion spring is installed at the hinge between the cover plate and the inner wall of the drain ditch, and the first torsion spring normally forces the cover plate to close in the first connecting groove; the buoyancy member includes a buoyancy bar and a pull rope, and the buoyancy bar is arranged in the drain ditch. One end of the pull rope is connected to the buoyancy bar, and the other end is connected to the cover plate. When the rainwater level in the drain ditch rises to the opening of the drain ditch, the buoyancy bar moves up and opens the cover plate.

[0009] By adopting the above-mentioned technical solution, through the arrangement of buoyancy bars and pull ropes, when the drainage pipe is blocked and the rainwater level in the drainage ditch continues to rise, the buoyancy bar is driven to float up, and the cover plate is pulled by the pull rope to open the first connecting groove, so that the rainwater can be discharged outward from the spare pipe, thereby improving the convenience of opening and closing the spare pipe.

[0010] Optionally, a filter chamber is provided between the drainage ditch and the spare chamber, the first connecting groove is connected to the filter chamber, two spare chambers are provided, each of the spare chambers is provided with the spare pipe, the top wall of each spare chamber is provided with a second connecting groove connected to the filter chamber, and the drainage ditch is connected to the spare chamber through the filter chamber; a filter net is installed on the inner wall of each of the second connecting grooves, and the surface of the filter net is kept flush with the bottom wall of the filter chamber; a movable box is slidably installed in the filter chamber, and a driving component is provided in the filter chamber for driving the movable box to slide back and forth along the width direction of the drainage ditch, and when the movable box slides back and forth, the movable box scrapes the filter nets of the two second connecting grooves in turn.

[0011] By adopting the above technical solution, through the setting of the filter net and the moving box, the filter net can filter the rainwater entering the spare cavity, reducing the possibility that foreign matter in the drainage ditch directly falls into the spare cavity and causes the standby pipe to be blocked; during the rainwater discharge process, the moving box is driven to slide back and forth by the driving component, and the moving box can scrape the filter nets of the two second connecting grooves in turn to reduce the possibility of filter net blockage. In addition, by setting two spare cavities, on the one hand, even if one spare pipe is blocked, another spare pipe can be used to ensure that the rainwater in the drainage ditch can be discharged outward in time, reducing the possibility of flooding in the basement; on the other hand, when the moving box scrapes the filter net corresponding to one of the second connecting grooves (this second connecting groove is blocked by the moving box so that the drainage speed is reduced), it can ensure that the other second connecting groove is in an unblocked state (i.e., an open state), thereby ensuring that the rainwater is continuously discharged outward and improving the drainage efficiency of the overall structure.

[0012] Optionally, the driving assembly includes a driving disk, an arc-shaped rack, a driving rack and a driving member, the driving disk is rotatably installed in the filter chamber, and the arc-shaped rack is coaxially arranged on the outer peripheral wall of the driving disk; the driving rack is installed on the side wall of the movable box and two driving racks are arranged, and both ends of the two driving racks are extended along the width direction of the drainage ditch, and the driving disk is located between the two driving racks. When the arc-shaped rack is engaged with one of the driving racks, the arc-shaped rack disengages from the other driving rack; the driving member is arranged on the driving disk to drive the driving disk to rotate.

[0013] By adopting the above-mentioned technical solution, through the arrangement of the driving disk, the arc-shaped rack, the driving rack and the driving member, the driving member drives the driving disk to rotate around its own central axis, so as to drive the arc-shaped rack to engage with the two driving racks in turn, thereby forcing the moving box to move back and forth along the width direction of the drainage ditch, so that the moving box can scrape the filter screens of the two second connecting grooves in turn, reducing the possibility of the filter screens being blocked.

[0014] Optionally, the mobile box has a fishing cavity for catching foreign objects, and two opposite side walls of the mobile box are provided with entrances connected to the fishing cavity, and each of the entrances is hinged with a side panel for opening and closing the entrance; the inner wall of the mobile box at the entrance is provided with a limit column, and the limit column is used to abut the side panel to limit the side panel from flipping outward.

[0015] By adopting the above-mentioned technical scheme, through the setting of the fishing cavity, side panels and limit columns, the limit columns are used to limit the side panels from flipping outward, that is, the side panels can only flip inward, so that when the mobile box moves, the side panels located at the front end of the moving direction of the mobile box flip inward under the action of water flow to open the corresponding entrance port, and the side panels located at the rear end of the moving direction of the mobile box abut against the limit columns under the action of water flow to close the corresponding entrance port, so that foreign objects scraped up by the mobile box during the movement of the mobile box can be collected in the fishing cavity, thereby ensuring the drainage efficiency of the overall structure.

[0016] Optionally, a crushing chamber is opened between the two spare chambers, and a rotating roller is rotatably installed in the crushing chamber, and the peripheral wall of the rotating roller is provided with a blade for crushing foreign matter; a third connecting groove connected to the filter chamber is opened on the top wall of the crushing chamber, and a drop-out port is opened on the bottom wall of the fishing chamber, and when the mobile box moves to the middle position of the filter chamber, the drop-out port is connected to the third connecting groove.

[0017] By adopting the above-mentioned technical solution and setting the blade, when the mobile box is displaced to the middle position of the filter chamber, the drop-out port is opposite to the third connecting groove, and the foreign matter in the capture chamber falls into the crushing chamber, driving the rotating roller to rotate, driving the blade to crush the foreign matter, and timely crushing the foreign matter captured by the mobile box, thereby reducing the possibility of foreign matter clogging each chamber.

[0018] Optionally, the top wall of the mobile box is provided with a plurality of first drain holes connected to the fishing cavity, and the mobile box is provided with an opening and closing assembly for opening and closing the first drain holes. When the mobile box moves to the middle position of the filter cavity, the top wall of the mobile box blocks the first connecting groove, and the opening and closing assembly opens the first drain hole. When the mobile box moves toward both sides of the filter cavity, the opening and closing assembly closes the first drain hole.

[0019] By adopting the above-mentioned technical scheme, through the arrangement of the first downhole and the opening and closing assembly, when the mobile box moves to the middle position of the filter chamber, the top wall of the mobile box blocks the first connecting groove, so that the rainwater discharged from the drainage ditch enters the fishing chamber only through the first downhole, thereby flushing the foreign matter in the fishing chamber into the crushing chamber for crushing, thereby improving the effect of foreign matter transfer; when the mobile box moves toward both sides of the filter chamber, the opening and closing assembly can close the first downhole, reduce the long-term water flow through the first downhole, and thereby reduce the possibility of blockage of the first downhole.

[0020] Optionally, the opening and closing assembly includes an opening and closing plate, a return spring and a guide block, the opening and closing plate is slidably installed in the fishing cavity, and a plurality of second water drop holes are provided on the plate surface of the opening and closing plate, and the first water drop holes and the second water drop holes are staggered; the return spring is arranged between the opening and closing plate and the inner wall of the fishing cavity, and when the mobile box moves to the middle position of the filter cavity, the return spring forces the opening and closing plate and the top wall of the fishing cavity to form a water drop gap; guide grooves are provided on both opposite side walls of the first connecting groove, and two guide blocks are provided and correspond to the two guide grooves, and the guide blocks are located at the top of the mobile box and connected to the opening and closing plate, and when the mobile box moves toward both sides of the filter cavity, the guide blocks are embedded in the corresponding guide grooves and force the opening and closing plate to fit the top wall of the fishing cavity.

[0021] By adopting the above-mentioned technical scheme, through the setting of the opening and closing plate, the return spring and the guide block, when the moving box is displaced toward the two sides of the filter chamber, the guide block is embedded in the guide groove, and under the action of the guide groove, the opening and closing plate is forced to fit the top wall of the fishing chamber; the first water drop hole and the second water drop hole are staggered, thereby closing the first water drop hole, so that rainwater does not pass through the first water drop hole but directly flows into the filter chamber, and is discharged to the spare chamber by the second connecting groove, thereby improving the drainage efficiency and reducing the possibility that rainwater will flush foreign matter in the fishing chamber back to the filter chamber; when the moving box moves to the middle position of the filter chamber (at this time the drop port is connected to the third connecting groove), the guide block disengages from the guide groove, and the opening and closing plate moves downward under the action of the return spring to form a water drop gap, so that rainwater in the drainage ditch can enter the fishing chamber and flush foreign matter in the fishing chamber into the crushing chamber for crushing, thereby greatly improving the foreign matter transfer effect.

[0022] Optionally, a plurality of top columns are provided on the upper surface of the opening and closing plate, and the plurality of top columns are arranged corresponding to a plurality of first water drop holes. When the opening and closing plate is attached to the top wall of the fishing cavity, the top columns are matched and plugged into the corresponding first water drop holes.

[0023] By adopting the above-mentioned technical solution and setting the top column, when the opening and closing plate is attached to the top wall of the fishing cavity, the top column can be inserted into the first water drop hole and eject foreign objects in the first water drop hole. As the moving box continues to move, the top column can be repeatedly inserted into the first water drop hole, thereby keeping the first water drop hole unobstructed.

[0024] Optionally, push areas are formed on both sides of the filter chamber, and the two push areas are arranged corresponding to the two entrances of the mobile box; the inner wall of each push area is provided with a flushing channel, and the end of the flushing channel away from the pushing area is connected to the drainage ditch; a sealing plate is hinged in the drainage ditch, and the sealing plate is normally closed at the inlet end of the flushing channel; the sealing plate is connected to an opening and closing component, and when the entrance of the mobile box moves into the corresponding pushing area, the opening and closing component forces the sealing plate to open the flushing channel.

[0025] By adopting the above-mentioned technical scheme, through the setting of the flushing flow channel and the opening and closing component, when the mobile box moves toward the pushing area (the foreign matter on the filter net is scraped off during the movement of the mobile box), the opening and closing component forces the sealing plate to open, and a part of the water in the drainage ditch can flow into the pushing area through the flushing flow channel, thereby flushing the foreign matter in the pushing area into the fishing cavity, so that the scraped foreign matter can enter the fishing cavity, which greatly improves the foreign matter capturing effect of the mobile box.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the provision of the backup cavity and the backup pipe, under normal conditions, the cover plate is closed to the first connecting groove, so that rainwater in the drainage ditch is discharged outwards through the drainage pipe; when foreign objects fall into the drainage ditch and cause the drainage pipe to be blocked, a large amount of rainwater gathers in the drainage ditch and cannot be discharged in time, causing the rainwater level in the drainage ditch to rise continuously. When the rainwater level in the drainage ditch rises to the opening of the drainage ditch, the buoyancy member drives the cover plate to flip to open the first connecting groove, and the rainwater in the drainage ditch can be discharged outwards through the backup pipe, so that the drainage ditch maintains good drainage performance and reduces the possibility of flooding in the basement; 2. Through the arrangement of the first water drop hole and the opening and closing assembly, when the mobile box moves to the middle position of the filter chamber, the top wall of the mobile box blocks the first connecting groove, so that the rainwater discharged from the drainage ditch enters the fishing chamber only through the first water drop hole, thereby flushing the foreign matter in the fishing chamber into the crushing chamber for crushing, thereby improving the effect of foreign matter transfer; when the mobile box moves toward the two sides of the filter chamber, the opening and closing assembly can close the first water drop hole, reducing the long-term water flow of the first water drop hole, thereby reducing the possibility of blockage of the first water drop hole; 3. Through the setting of the flushing flow channel and the opening and closing components, when the mobile box moves toward the pushing area (the foreign matter on the filter net is scraped off during the movement of the mobile box), the opening and closing component forces the sealing plate to open, and a part of the water in the drainage ditch can flow into the pushing area through the flushing flow channel, thereby flushing the foreign matter in the pushing area into the fishing cavity, so that the scraped foreign matter can enter the fishing cavity, which greatly improves the foreign matter capturing effect of the mobile box.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Fig.10 This application is described in further detail.

[0030] Embodiment 1: The embodiment of the present application discloses a basement waterproof structure.

[0031] Reference Figure 1 The basement waterproof structure includes a drainage ditch 1, a filter grating 11 and a drainage pipe 12. The drainage ditch 1 is located at the bottom of the slope of the basement. The filter grating 11 is installed at the opening of the drainage ditch 1 and multiple filter gratings 11 are arranged along the length direction of the drainage ditch 1; the drainage pipe 12 is buried at one side of the drainage ditch 1, and one end of the drainage pipe 12 is connected to the drainage ditch 1 for discharging rainwater to the outside.

[0032] Reference Figure 1 In this embodiment, a spare cavity 2 is provided at the bottom of the drainage ditch 1, and a spare pipe 21 is buried at one side of the spare cavity 2. One end of the spare pipe 21 is connected to the spare cavity 2 for discharging rainwater outward; a first connecting groove 13 is provided on the bottom wall of the drainage ditch 1, and the first connecting groove 13 is connected to the spare cavity 2. The drainage ditch 1 and the spare cavity 2 are connected to each other through the first connecting groove 13; two cover plates 14 for opening and closing the first connecting groove 13 are hinged to the bottom wall of the drainage ditch 1, and a first torsion spring (not shown in the figure) is installed at the hinge between each cover plate 14 and the bottom wall of the drainage ditch 1. The first torsion spring normally forces the plate surface of the cover plate 14 to rotate to a horizontal state to close the first connecting groove 13.

[0033] Reference Figure 1 A buoyancy member 3 is installed between the drain ditch 1 and each cover plate 14. When the rainwater level in the drain ditch 1 rises to the opening of the drain ditch 1, the buoyancy member 3 drives the cover plate 14 to flip over to open the first connecting groove 13; the buoyancy member 3 includes a buoyancy bar 31 and a pull rope 32. The buoyancy bar 31 is arranged in the drain ditch 1. The buoyancy bar 31 can be a foam bar or an air bag. In this embodiment, the buoyancy bar 31 is made of foam; a penetration ring 16 is installed on the inner wall of the drain ditch 1. One end of the pull rope 32 is fixedly connected to the buoyancy bar 31, and the other end passes through the penetration ring 16 and is fixedly connected to the plate surface of the cover plate 14. When the rainwater level in the drain ditch 1 rises to the opening of the drain ditch 1, the buoyancy bar 31 moves up and opens the cover plate 14.

[0034] The implementation principle of Example 1 of the present application is as follows: under normal conditions, the cover plate 14 is closed to the first connecting groove 13, so that rainwater in the drainage ditch 1 is discharged outwardly through the drainage pipe 12; when foreign objects fall into the drainage ditch 1 and cause the drainage pipe 12 to be blocked, a large amount of rainwater gathers in the drainage ditch 1 and cannot be discharged in time, causing the rainwater level in the drainage ditch 1 to continue to rise. When the rainwater level in the drainage ditch 1 rises to the opening of the drainage ditch 1, the buoyancy member 3 drives the cover plate 14 to flip over to open the first connecting groove 13, and the rainwater in the drainage ditch 1 can be discharged outwardly through the backup pipe 21, so that the drainage ditch 1 maintains good drainage performance and reduces the possibility of flooding in the basement.

[0035] Embodiment 2: The embodiment of the present application discloses a basement waterproof structure.

[0036] Reference Figure 2 The difference between the basement waterproof structure disclosed in the embodiment of the present application and the embodiment 1 is that: In the present embodiment, there are two spare chambers 2, which are arranged side by side along the width direction of the drainage ditch 1, and each spare chamber 2 is correspondingly provided with a spare pipe 21; a filter chamber 4 is opened between the drainage ditch 1 and the two spare chambers 2, and the first connecting groove 13 is connected to the filter chamber 4, and a second connecting groove 22 is opened on the top wall of each spare chamber 2, and the second connecting groove 22 is connected to the filter chamber 4, and the drainage ditch 1 is connected to the spare chamber 2 through the filter chamber 4.

[0037] Reference Figure 2 , Figure 3 , Figure 4 A filter screen 23 is installed on the inner wall of each second connecting groove 22, and the surface of the filter screen 23 is kept flush with the bottom wall of the filter chamber 4; a moving box 5 is slidably installed in the filter chamber 4, and a driving component 6 is provided in the filter chamber 4 for driving the moving box 5 to slide back and forth along the width direction of the drainage ditch 1. When the moving box 5 slides back and forth, the bottom wall of the moving box 5 scrapes the filter screens 23 of the two second connecting grooves 22 in turn.

[0038] The driving assembly 6 includes a driving disk 61, an arcuate rack 62, a driving rack 63 and a driving member 64. The driving disk 61 is rotatably installed in the filter chamber 4 and is located on one side of the mobile box 5. The arcuate rack 62 is fixedly installed on the outer peripheral wall of the driving disk 61. The arcuate rack 62 is arranged in an arc shape around the central axis of the driving disk 61; the driving rack 63 is installed on the side wall of the mobile box 5 close to the driving disk 61. There are two driving racks 63. Both ends of the two driving racks 63 are extended along the width direction of the drainage ditch 1. The driving disk 61 is located between the two driving racks 63. The arcuate rack 62 is used for meshing and transmitting with the two driving racks 63. When the arcuate rack 62 meshes with one of the driving racks 63, the arcuate rack 62 disengages from the other driving rack 63.

[0039] Reference Figure 3 , a driving member 64 is arranged on the driving disk 61 to drive the driving disk 61 to rotate, a mounting cavity 43 is provided on one side of the filter cavity 4, a driving roller 44 is rotatably mounted in the mounting cavity 43, one end of the driving roller 44 extends into the filter cavity 4 and is coaxially connected to the driving disk 61, and the driving disk 61 is rotatably mounted in the filter cavity 4 through the driving roller 44; in this embodiment, the driving member 64 is arranged as a driving motor, the driving motor is fixedly mounted on the inner wall of the mounting cavity 43, and the output shaft of the driving motor is coaxially connected to the driving roller 44. It should be noted that one side of the mounting cavity 43 has a mounting port (not shown in the figure) connected to the outside world, so as to facilitate the installation of the driving motor and subsequent maintenance work.

[0040] Reference Figure 2 , Figure 3The mobile box 5 is hollow. For the convenience of description, the space inside the mobile box 5 is defined as a fishing cavity 51 below. The fishing cavity 51 is used to catch foreign objects that fall from the drainage ditch 1 into the filter cavity 4; the two opposite side walls of the mobile box 5 are provided with an entrance 52 connected to the fishing cavity 51, and each entrance 52 is hinged with a side panel 53 for opening and closing the entrance 52; a limiting column 54 is fixedly installed on the inner wall of the mobile box 5 at the entrance 52, and the limiting column 54 is located on the side of the side wall away from the fishing cavity 51. The board surface of the side panel 53 rotates to a vertical state under the action of its own gravity and abuts against the outer peripheral wall of the limiting column 54, so that the limiting column 54 can limit the side panel 53 from flipping outward (that is, the side panel 53 can only flip toward the fishing cavity 51).

[0041] The implementation principle of the second embodiment of the present application is as follows: the filter screen 23 can filter the rainwater entering the standby chamber 2, reducing the possibility that foreign matter in the drainage ditch 1 directly falls into the standby chamber 2 and causes the standby pipe 21 to be blocked; during the rainwater discharge process, the driving assembly 6 drives the moving box 5 to slide back and forth, and the moving box 5 can scrape the filter screens 23 of the two second connecting grooves 22 in turn to reduce the possibility of the filter screens 23 being blocked. In addition, by setting two standby chambers 2, on the one hand, even if one standby pipe 21 is blocked, another standby pipe 21 can be used to ensure that the rainwater in the drainage ditch 1 can be discharged outward in time, reducing the possibility of flooding in the basement; on the other hand, when the moving box 5 scrapes the filter screen 23 corresponding to one of the second connecting grooves 22 (this second connecting groove 22 is blocked by the moving box 5 so that the drainage speed is reduced), it can ensure that the other second connecting groove 22 is in an unblocked state (i.e., an open state), thereby ensuring that the rainwater is continuously discharged outward, and improving the drainage efficiency of the overall structure.

[0042] The limiting column 54 is used to limit the side panel 53 from flipping outward, so that the side panel 53 can only flip inward, so that when the mobile box 5 moves, the side panel 53 located at the front end of the moving direction of the mobile box 5 flips inward under the action of the water flow to open the corresponding entrance 52, and the side panel 53 located at the rear end of the moving direction of the mobile box 5 abuts against the limiting column 54 under the action of the water flow to close the corresponding entrance 52, so that during the movement of the mobile box 5, foreign matter scraped by the mobile box 5 can be collected in the fishing cavity 51, thereby ensuring the drainage efficiency of the overall structure.

When the moving box 5 moves to the middle position of the filter chamber 4, the material drop opening 55 is connected to the third connecting groove 73 and the moving box 5 closes the two second connecting grooves 22.

[0046] The implementation principle of Example 3 of the present application is: when the mobile box 5 is displaced to the middle position of the filter chamber 4, the drop-out port 55 is opposite to the third connecting groove 73, and the foreign matter collected in the capture chamber 51 falls into the crushing chamber 7, and the blade 72 can crush the foreign matter, and the foreign matter captured by the mobile box 5 is crushed in time, reducing the possibility of foreign matter clogging each chamber.

The top wall of the fishing cavity 51 is installed with a guide column 57, and the guide column 57 is penetrated by the opening and closing plate 81. The opening and closing plate 81 is slidably installed in the fishing cavity 51 through the guide column 57; a plurality of second water drop holes 811 are opened on the plate surface of the opening and closing plate 81, and all the first water drop holes 56 and all the second water drop holes 811 are staggered; the return spring 82 is sleeved on the guide column 57, one end of the return spring 82 is fixedly connected to the opening and closing plate 81, and the other end is fixedly connected to the top wall of the fishing cavity 51. When the moving box 5 moves to the middle position of the filter cavity 4, the return spring 82 forces the opening and closing plate 81 and the top wall of the fishing cavity 51 to form a water drop gap 812.

[0050] Reference Figure 8 , guide grooves 131 are provided on the two opposite side walls of the first connecting groove 13, and two guide blocks 83 are provided and correspond to the two guide grooves 131; the guide block 83 is located at the top of the movable box 5, and the guide block 83 is installed with a connecting frame 831, one end of the connecting frame 831 is connected to the guide block 83, and the other end penetrates into the fishing cavity 51 and is fixedly connected to the opening and closing plate 81; each guide groove 131 has a guiding surface 132 for forcing the guide block 83 to be lifted, and when the movable box 5 moves toward the two sides of the filter cavity 4, the guide block 83 is embedded in the corresponding guide groove 131 and then lifted, and forces the opening and closing plate 81 to fit the top wall of the fishing area.

[0051] A plurality of top columns 813 are fixedly mounted on the upper surface of the opening and closing plate 81, and the plurality of top columns 813 are arranged corresponding to the plurality of first water drop holes 56. When the opening and closing plate 81 is attached to the top wall of the fishing area, each top column 813 is matched and plugged into the corresponding first water drop hole 56, and when the top column 813 is plugged into the corresponding first water drop hole 56, the top wall of the top column 813 remains flush with the top wall of the mobile box 5.

[0052] The implementation principle of Example 4 of the present application is as follows: when the moving box 5 is displaced toward the two sides of the filter chamber 4, the guide block 83 is embedded in the guide groove 131, and under the action of the guide groove 131, the opening and closing plate 81 is forced to fit the top wall of the fishing area; the first water drop hole 56 and the second water drop hole 811 are staggered, thereby closing the first water drop hole 56, so that rainwater does not pass through the first water drop hole 56 but directly flows into the filter chamber 4, and is discharged to the spare chamber 2 by the second connecting groove 22, thereby improving the drainage efficiency and reducing the possibility that rainwater will flush foreign matter in the fishing area back to the filter chamber 4; when the moving box 5 moves to the middle position of the filter chamber 4 (at this time the drop port 55 is connected to the third connecting groove 73), the guide block 83 is disengaged from the guide groove 131, and the opening and closing plate 81 moves downward under the action of the reset spring 82 to form a water drop gap 812, so that rainwater in the drainage ditch 1 can enter the fishing area and flush foreign matter in the fishing area into the crushing chamber 7 for crushing, thereby greatly improving the foreign matter transfer effect.

[0053] Embodiment 5: The embodiment of the present application discloses a basement waterproof structure.

[0054] Reference Fig. 9 , Fig.10 The difference between the basement waterproof structure disclosed in the embodiment of the present application and embodiment 2 is that: In this embodiment, for the convenience of description, the areas on both sides of the filter chamber 4 (the areas where the two second connecting grooves 22 are far away from each other) are defined as push areas 41, and the two push areas 41 are arranged corresponding to the two entrances 52 of the mobile box 5; the inner wall of each push area 41 is provided with a flushing channel 42, and the end of the flushing channel 42 away from the push area 41 is connected to the drainage ditch 1.

[0055] A sealing plate 15 is installed in the drain ditch 1, and one side of the sealing plate 15 is hinged to the flushing channel 42 of the drain ditch 1; a second torsion spring (not shown in the figure) is installed between the hinge of the sealing plate 15 and the inner wall of the drain ditch 1, and the second torsion spring normally forces the plate surface of the sealing plate 15 to rotate to a vertical state to close the inlet end of the flushing channel 42; the sealing plate 15 is connected to an opening and closing component 9, and when the entrance port 52 of the moving box 5 moves into the corresponding pushing area 41, the opening and closing component 9 forces the sealing plate 15 to open the flushing channel 42.

[0056] Reference Fig. 9 , Fig.10A gravity block 151 is fixedly installed on the surface of the sealing plate 15. The gravity block 151 normally forces the sealing plate 15 to press against the inlet end of the flushing channel 42 to improve the sealing effect of the sealing plate 15. A lifting groove is opened on the top wall of the pushing area 41. The opening and closing component 9 includes a guide block 91, a compression spring 92 and a push rod 93. The guide block 91 is slidably installed in the lifting groove. One end of the compression spring 92 is fixedly connected to the guide block 91, and the other end is fixedly connected to the inner wall of the lifting groove. The compression spring 92 normally forces the guide block 91 to be partially exposed in the lifting groove.

[0057] One end of the push rod 93 is fixedly connected to the guide block 91, and the other end penetrates into the drainage ditch 1 and extends to the bottom of the gravity block 151; the guide block 91 has a guide surface 911. When the moving box 5 moves into the pushing area 41, the moving box 5 pushes the guide block 91 to be lifted through the guide surface 911, and pushes the gravity block 151 through the push rod 93 to force the sealing plate 15 to flip over and open the inlet end of the flushing channel 42.

[0058] The implementation principle of the embodiment 5 of the present application is as follows: when the mobile box 5 moves toward the push area 41 (the foreign matter on the filter screen 23 is scraped off during the movement of the mobile box 5), the mobile box 5 pushes the gravity block 151 through the push rod 93, forcing the sealing plate 15 to flip and open the inlet end of the flushing channel 42, and a part of the water in the drainage ditch 1 can flow into the push area 41 through the flushing channel 42, thereby flushing the foreign matter in the push area 41 into the catching chamber 51, so that the scraped foreign matter can enter the catching chamber 51, greatly improving the catching effect of the mobile box 5 on foreign matter. The combination of the gravity block 151 and the torsion spring enables the sealing plate 15 to be firmly blocked at the inlet end of the flushing channel 42, thereby improving the closing effect of the sealing plate 15.

[0059] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
