Technical Field

[0001] The invention belongs to the technical field of drainage equipment, and in particular relates to a waterlogging prevention and drainage device for urban pothole-prone roads. Background Art

[0002] With the continuous progress of society, the process of urbanization is also accelerating. In the process of urban construction, the drainage system is of paramount importance, which is directly related to people's urban life experience. The drainage system covers a wide range, including various infrastructure and related equipment. For example, there are generally drainage wells on the roadsides of cities, which are connected to the overall drainage pipelines of the city. These drainage wells are generally equipped with drainage devices at their own water inlets, so as to filter the water at the water inlet, prevent objects or people from accidentally falling, and ensure safety during use.

[0003] When in use, the existing urban pothole-proof and drainage devices are generally in a traditional grid shape, so as to achieve the functions of rapid drainage and protection. However, in actual application, due to the low geographical location of urban potholes, the connection length between the drainage wells and the overall urban drainage pipelines is shorter than that in other areas. Since the overall urban drainage pipelines collect sewage from various places, the internal air quality is low. This causes the drainage wells at the urban potholes to easily spread the odor in the overall urban drainage pipelines, affecting people's urban life experience. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a flood prevention and drainage device for urban pothole-shaped roads, which solves the problem that the existing flood prevention and drainage device for urban pothole-shaped roads easily spreads odor outward.

[0008] As a further solution of the present invention: an assembly part is installed on the outer side wall of the installation enclosure, and assembly holes are opened at the four corners of the top of the assembly part.

[0009] As a further solution of the present invention: an inner cavity is reserved inside the blocking floating plate, and a gap is reserved between the blocking floating plate and the first grid filter plate.

[0010] As a further solution of the present invention: a filter plate body is installed on the top of the blocking floating plate, and the filter plate body extends to the inside of the receiving groove, and the height of the filter plate body is less than the depth of the receiving groove.

[0011] As a further solution of the present invention: the operating mechanism includes a threaded rod, the threaded rod passes through the bottom of the second installation groove, and the threaded rod extends to the inside of the first installation groove, and an anti-slip ring is installed on the outer side of the threaded rod near the bottom end.

[0012] As a further solution of the present invention: the central axis of the threaded rod is perpendicular to the transverse central axis of the first grid filter plate, and the threaded rod is threadedly connected to the first grid filter plate.

[0013] As a further solution of the present invention: the operating mechanism further comprises a closing plate, the closing plate passes through the top of one side inside the second installation groove, and a second spring is connected between the closing plate and the first grid filter plate.

[0014] As a further solution of the present invention: the cross-sectional shape of the extruded part is a trapezoid, and the extruded part and the anti-slip plate are manufactured in one piece.

[0016] As a further solution of the present invention: the third grid filter plate and the movable mounting plate are manufactured in an integrated manner, and the filter holes on the third grid filter plate are staggered with the filter holes on the second grid filter plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the initial state, only a gap is left between the blocking float and the first grille filter plate as a regular drainage hole, and the movable block and the first grille filter plate are connected by a first spring, so that under normal conditions, the diffusion of odor can be greatly reduced. At the same time, when the drainage pressure is high, the water pressure will drive the gap between the blocking float and the first grille filter plate to increase, thereby achieving a smooth drainage task.

[0019] 2. By arranging an extrusion piece on the movable block, when the drainage pressure is extremely high, the blocking float will fully move downward under the action of the water pressure, and then the extrusion piece will drive the third grid filter plate to move horizontally, so that the filter holes on the third grid filter plate coincide with the filter holes on the second grid filter plate, and then the drainage volume can be further increased when necessary to reduce the drainage pressure.

[0020] 3. The height of the filter plate body is smaller than the depth of the receiving groove, so that when the drainage well is full of water and backflow occurs, the blocking floating plate can fit with the first grid filter plate under the action of the water pressure and buoyancy below, thereby sealing the first grid filter plate, thereby reducing the occurrence of backflow;

[0021] 4. Through the threaded connection between the threaded rod and the first grid filter plate, when necessary, the staff can manually adjust the gap between the blocking floating plate and the first grid filter plate by rotating the threaded rod, thereby achieving artificial adjustment of the drainage capacity.

DETAILED DESCRIPTION

[0030] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 7 As shown, the present invention provides a technical solution:

[0032] Example 1

[0033] A device for preventing waterlogging and draining a pothole road in an urban area comprises a mounting enclosure 1, an outer wall of the mounting enclosure 1 is mounted with an assembly part 2, and four corners of the top of the assembly part 2 are provided with assembly holes 3. During use, the device can be mounted at the opening of a drainage well by means of screws or the like;

[0034] The first grille filter plates 4 are installed at both ends of the installation enclosure 1, and the first installation grooves 5 are provided on both sides of the bottom of the first grille filter plate 4. A movable block 6 is provided inside the first installation groove 5, and a first spring 7 is connected between the movable block 6 and the first grille filter plate 4. A blocking float 8 is installed at the bottom of the movable block 6. A receiving groove 10 is provided at the edge of the bottom of the first grille filter plate 4. An inner cavity 9 is reserved inside the blocking float 8, and a gap is left between the blocking float 8 and the first grille filter plate 4. The gap between the blocking float 8 and the first grille filter plate 4 is only used for the discharge of a small amount of water flow under normal conditions, so that under normal conditions, it is difficult for the wellhead of the drainage well to diffuse too much air containing odors, etc. outward;

[0035] A filter plate body 11 is installed on the top of the blocking float 8, and the filter plate body 11 extends to the interior of the receiving groove 10. The height of the filter plate body 11 is less than the depth of the receiving groove 10, and the filter holes on the filter plate body 11 are small, which further reduces the diffusion of odorous air outward. At the same time, the blocking float 8 can be made of lightweight materials, so that when the drainage well itself is full of water, under the water pressure below and the buoyancy of the blocking float 8, the blocking float 8 can rise and fit with the first grid filter plate 4, and the filter plate body 11 is inserted into the interior of the receiving groove 10, so that the entire drainage device is fully closed, thereby avoiding the occurrence of backflow and the like.

[0036] Example 2

[0037] Based on the above-mentioned embodiment 1, second mounting grooves 12 are provided on both sides of the top of the first grid filter plate 4, and an operating mechanism for squeezing the movable block 6 is arranged inside the second mounting groove 12, and the operating mechanism includes a threaded rod 13, the threaded rod 13 passes through the bottom of the second mounting groove 12, and the threaded rod 13 extends to the inside of the first mounting groove 5, and an anti-slip ring 14 is installed on the outer side of the threaded rod 13 near the bottom, and the central axis of the threaded rod 13 is perpendicular to the transverse central axis of the first grid filter plate 4, and the threaded rod 13 is threadedly connected to the first grid filter plate 4, so that the staff can manually adjust the threaded rod 13 by rotating the threaded rod 13, so that the threaded rod 13 actively squeezes the movable block 6, and then the height of the blocking float 8 can be manually adjusted when necessary, so that the drainage volume is increased. For example, when there is not much accumulated water, but it needs to be discharged quickly, the staff can increase the size of the gap between the blocking float 8 and the first grid filter plate 4 by rotating the threaded rod 13 to quickly drain the water;

[0038] The operating mechanism also includes a closing plate 15, which passes through the top of one side of the second mounting groove 12. A second spring 16 is connected between the closing plate 15 and the first grid filter plate 4, so that under normal conditions, the closing plate 15 will close the second mounting groove 12, thereby ensuring that the top of the mounting enclosure 1 is basically flat. By protecting the threaded rod 13, when the threaded rod 13 needs to be operated, the staff can manually slide the closing plate 15 to release the closure of the second mounting groove 12. A finger groove can be opened on the top of the closing plate 15 to facilitate operation by the staff.

[0039] Example 3

[0040] Based on the above-mentioned embodiments 1 and 2, an extrusion piece 17 is installed on the side of the movable block 6 away from the first grid filter plate 4, and an anti-drop plate 18 is installed on the side of the extrusion piece 17 away from the movable block 6, and a second grid filter plate 19 is installed on both sides of the interior of the mounting enclosure 1, and a third mounting groove 20 is opened on both sides of the interior of the mounting enclosure 1. A movable mechanism for closing the second grid filter plate 19 is arranged inside the third mounting groove 20, and the movable mechanism includes a movable mounting plate 21, which is arranged inside the third mounting groove 20, and a third mounting plate 21 is connected to the mounting enclosure 1. Three springs 22, a third grille filter plate 23 is installed on one side of the movable mounting plate 21 close to the first grille filter plate 4, a pressure plate 24 is installed on the side of the third grille filter plate 23 away from the movable mounting plate 21, and the pressure plate 24 penetrates the first grille filter plate 4 and extends to the inside of the first mounting groove 5, the third grille filter plate 23 and the movable mounting plate 21 are made as one piece, and the filter holes on the third grille filter plate 23 are staggered with the filter holes on the second grille filter plate 19, so that under normal conditions, the third grille filter plate 23 can form a seal with the second grille filter plate 19, thereby ensuring the reduction of the diffusion of odorous air;

[0041] The cross-sectional shape of the extrusion piece 17 is a trapezoid, and the extrusion piece 17 and the anti-slip plate 18 are made in one piece, so that when the movable block 6 blocks the floating plate 8 from moving downward due to the increase in drainage pressure, the oblique edge portion of the extrusion piece 17 will squeeze the pressure plate 24, causing the third grid filter plate 23 to slide to one side. When the filter holes on the third grid filter plate 23 overlap with the filter holes on the second grid filter plate 19, the closure of the second grid filter plate 19 is released, thereby further enhancing the drainage capacity, and thus fully ensuring the drainage capacity when necessary.

[0042] Working principle of the present invention: the device is installed at the wellhead of the drainage well. Under normal conditions, there is a small gap between the blocking floating plate 8 and the first grid filter plate 4 for basic drainage. At the same time, the second grid filter plate 19 is completely closed, and then cooperates with the filter plate body 11 to fully reduce the diffusion of odorous air in the drainage well.

[0043] When the drainage pressure increases, under the action of water pressure, the blocking floating plate 8 will move downward, thereby increasing the gap between the blocking floating plate 8 and the first grid filter plate 4, thereby increasing the drainage capacity autonomously. When the drainage pressure further increases, the blocking floating plate 8 moves further downward, and at this time, the beveled portion of the extrusion member 17 drives the pressure plate 24 to move laterally by a sufficient amplitude, so that the filter holes on the third grid filter plate 23 and the filter holes on the second grid filter plate 19 begin to overlap, thereby releasing the closure of the second grid filter plate 19, thereby further increasing the drainage capacity.

[0044] Because it is located in a low-lying position, when the drainage well itself is full of water, as mentioned above, under the action of the bottom water pressure and the buoyancy of the blocking floating plate 8, the blocking floating plate 8 will fit with the first grid filter plate 4, thereby closing the device, thereby avoiding the occurrence of backflow and the like;

[0045] When the drainage pressure is not large, but rapid drainage is required, the staff can slide the closing plate 15 to release the closure of the second mounting groove 12, and rotate the threaded rod 13 in the forward direction, so that the threaded rod 13 actively squeezes the movable block 6 downward, thereby actively increasing the gap between the blocking floating plate 8 and the first grille filter plate 4, thereby actively increasing the drainage capacity and achieving rapid drainage tasks.

[0046] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
