Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage well cover technology, and more specifically to a drainage well cover for municipal roads. Background Technology
[0002] Drainage manhole covers are an important component of urban drainage systems. Common drainage manhole covers mainly consist of the cover body, frame, rubber gasket, and inspection well. The specific disassembly process for common drainage manhole covers is as follows: 1. Preparation: Safety warnings: Set up fences and warning signs; provide lighting at night; prepare disassembly tools, including pry bars and protective devices; 2. Disassembly process: Remove silt and gravel from the manhole cover surface to prevent debris from falling into the manhole; insert a pry bar into the edge holes or gaps of the manhole cover and slowly pry it up; after the manhole cover body is completely lifted, move it horizontally to a stable location to prevent it from rolling; cover with a temporary protective board to prevent people or objects from falling in;
[0003] However, in actual operation, we found that the above disassembly process is too cumbersome and requires the use of special tools. At the same time, the disassembly process requires professional training, which leads to a waste of manpower. In addition, when the existing drainage well cover is installed on the surface of the well base, the two are not in a fully restrained state. Therefore, under the drive of external force, the well cover body may be displaced or tilted. Under the action of external force, the well cover may deform later, which will lead to the failure of the well cover and thus cause certain economic losses.
[0004] Therefore, there is an urgent need for a drainage well cover for municipal roads to solve the problems mentioned above. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drainage well cover for municipal roads to solve the problems existing in the background art.
[0006] This utility model provides the following technical solution: a drainage well cover for municipal roads, comprising:
[0007] A drainage well cover is used for drainage on municipal roads. A well frame is installed on the side of the bottom of the drainage well cover. The well frame is set on the municipal road to fix the drainage well cover. A card plate is installed on one side of the well frame. The card plate has a card groove on the inner wall near the drainage well cover.
[0008] The drainage well cover has a limiting groove on its top near the card plate, and a drainage hole is provided on the inner wall of the drainage well cover near the limiting groove to drain the water inside the limiting groove.
[0009] Preferably, the limiting groove has torsion spring columns installed on the inner walls of both sides away from the well frame, the torsion spring columns have torsion spring devices installed on the inner walls near the limiting groove, and the torsion spring columns have handles installed at the ends away from the limiting groove.
[0010] Preferably, a hollow column is installed on the bottom surface of the limiting groove, a lifting column is movably sleeved on the inner wall of the top of the hollow column, and a limiting frame is installed on the upper surface of the lifting column.
[0011] The inner wall of the limiting frame is covered with a friction rubber layer for clamping the limiting handle.
[0012] Preferably, a sliding plate is installed on the bottom surface of the lifting column, and a first spring is vertically installed on the bottom surface of the sliding plate. The end of the first spring away from the sliding plate is installed on the inner side of the bottom of the hollow column.
[0013] A long magnetic rod is installed in the middle area of the bottom surface of the sliding plate, and a first magnetic block is installed in the middle area of the inner side of the bottom of the hollow column. Magnetic repulsion will be generated between the long magnetic rod and the first magnetic block.
[0014] Preferably, the inner wall of the drainage well cover is provided with an auxiliary sliding groove near the limiting groove. A limiting block is sleeved in the auxiliary sliding groove. A slider is installed at the bottom of the limiting block and is movably sleeved on the bottom inner wall of the limiting groove. A U-shaped plate is provided on the side of the limiting block away from the limiting groove and is movably sleeved in the auxiliary sliding groove.
[0015] Preferably, a limiting plate is installed on the side of the U-shaped plate away from the limiting block, and a locking block is installed on the side of the limiting plate away from the U-shaped plate. The outer side of the locking block away from the limiting plate is adapted to the inner wall of the slot opened inside the drainage well cover. Second springs are installed on both sides of the limiting plate away from the U-shaped plate, and one end of the second spring away from the limiting plate is vertically installed in the auxiliary slide groove.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. This utility model moves the handle towards the position of the limiting frame by pressing the handle. At this time, a certain magnetic repulsion force is generated between the long rod of the magnetic block and the first magnetic block. At the same time, the first spring is compressed to a certain length and generates a corresponding spring force. At this time, the magnetic repulsion force and the spring force are greater than the corresponding clamping force generated by the torsion spring device and the limiting block. Therefore, under the action of the magnetic repulsion force between the long rod of the magnetic block and the first magnetic block and the first spring, the limiting frame drives the handle to disengage from the inner wall of the limiting groove. The handle tilts out of the limiting groove to facilitate the opening and disassembly of the drainage well cover by the staff.
[0018] 2. In this utility model, when the handle is inserted into the limiting frame, the handle squeezes the limiting block, thereby driving the limiting block to squeeze the U-shaped plate and the limiting plate, which in turn drives the locking block to be inserted into the slot inside the drainage well cover, so as to help limit the drainage well cover to the inner side of the well frame and further enhance the stability of the drainage well cover and well frame.

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The drainage well cover for municipal roads involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Reference Figures 1 to 2 As shown, this utility model provides a drainage well cover for municipal roads, comprising:
[0027] A drainage well cover 1 is used for drainage of municipal roads. A well frame 101 is installed on the side of the bottom of the drainage well cover 1. The well frame 101 is set on the municipal road and is used to fix the drainage well cover 1. A card plate 102 is installed on one side of the well frame 101. The card plate 102 has a card groove on the inner wall near the drainage well cover 1.
[0028] The drainage well cover 1 has a limiting groove 104 on its top near the card plate 102, and a drainage hole 103 is provided on the inner wall near the limiting groove 104 to drain the water inside the limiting groove 104.
[0029] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: the manhole frame 101 is installed on the municipal road. After the manhole frame 101 is installed, the drainage manhole cover 1 is installed inside the manhole frame 101, thus completing the installation of the drainage manhole cover 1 on the municipal road.
[0030] Reference Figures 1 to 2 As shown, this utility model provides a drainage well cover for municipal roads. The limiting groove 104 has torsion spring columns 201 installed on the inner walls on both sides away from the well frame 101. The torsion spring columns 201 have torsion spring devices installed on the inner walls near the limiting groove 104. A handle 2 is installed at one end of the torsion spring column 201 away from the limiting groove 104.
[0031] Reference Figures 1 to 4 As shown, this utility model provides a drainage well cover for municipal roads. A hollow column 302 is installed on the bottom surface of the limiting groove 104, and a lifting column 301 is movably sleeved on the inner wall of the top of the hollow column 302. A limiting frame 3 is installed on the upper surface of the lifting column 301.
[0032] The inner wall of the limiting frame 3 is covered with a friction rubber layer for clamping the limiting handle 2;
[0033] The bottom surface of the lifting column 301 is equipped with a sliding plate 303, and a first spring 305 is vertically installed on the bottom surface of the sliding plate 303. One end of the first spring 305 away from the sliding plate 303 is installed on the inner side of the bottom of the hollow column 302.
[0034] A magnetic rod 304 is installed in the middle area of the bottom surface of the sliding plate 303, and a first magnetic block 306 is installed in the middle area of the inner side of the bottom of the hollow column 302. Magnetic repulsion will be generated between the magnetic rod 304 and the first magnetic block 306.
[0035] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: the handle 2 is manually driven to rotate counterclockwise by 90 degrees. After the handle 2 rotates to the corresponding angle, the handle 2 is inserted into the inner wall of the limiting frame 3. Under the action of the friction rubber layer inside the limiting frame 3, the handle 2 is clamped and limited to the inner wall of the limiting frame 3. At the same time, under the action of the limiting block 4 and the torsion spring device, the handle 2 is in the current state of rotating counterclockwise by 90 degrees.
[0036] When the drainage well cover 1 is disassembled, the worker presses the handle 2 to move it to the position of the limiting frame 3. At this time, a certain magnetic repulsion force is generated between the magnetic block rod 304 and the first magnetic block 306. At the same time, the first spring 305 is compressed to a certain length and generates a corresponding spring force. At this time, the magnetic repulsion force and the spring force are greater than the corresponding clamping force generated by the torsion spring device and the limiting block 4. Therefore, under the action of the magnetic repulsion force between the magnetic block rod 304 and the first magnetic block 306 and the spring of the first spring 305, the limiting frame 3 drives the handle 2 to disengage from the inner wall of the limiting groove 104. The handle 2 tilts out of the interior of the limiting groove 104 to facilitate the worker to pick it up.
[0037] Reference Figures 1 to 2 as well as Figure 5 As shown, this utility model provides a drainage manhole cover for municipal roads. The inner wall of the drainage manhole cover 1 is provided with an auxiliary sliding groove near the limiting groove 104. A limiting block 4 is sleeved in the auxiliary sliding groove. A slider 401 is installed at the bottom of the limiting block 4. The slider 401 is movably sleeved on the bottom inner wall of the limiting groove 104. A U-shaped plate 402 is provided on the side of the limiting block 4 away from the limiting groove 104. The U-shaped plate 402 is movably sleeved in the auxiliary sliding groove.
[0038] A limiting plate 403 is installed on the side of the U-shaped plate 402 away from the limiting block 4. A locking block 405 is installed on the side of the limiting plate 403 away from the U-shaped plate 402. The outer side of the locking block 405 away from the limiting plate 403 is adapted to the inner wall of the slot opened inside the drainage well cover 1. Second springs 404 are installed on both sides of the limiting plate 403 away from the U-shaped plate 402. One end of the second spring 404 away from the limiting plate 403 is vertically installed in the auxiliary slide groove.
[0039] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: when the handle 2 is inserted into the limiting frame 3, the handle 2 squeezes the limiting block 4, thereby driving the limiting block 4 to squeeze the U-shaped plate 402 and the limiting plate 403, thereby driving the card block 405 to be inserted into the card groove inside the drainage well cover 1, so as to help limit the drainage well cover 1 to the inner side of the well frame 101, and further enhance the stability of the drainage well cover 1 and the well frame 101.
[0040] The specific workflow for this application is as follows:
[0041] Step 1: Manually drive handle 2 to rotate 90 degrees counterclockwise. After the handle 2 rotates to the corresponding angle, it will be inserted into the inner wall of the limiting frame 3. Under the action of the friction rubber layer inside the limiting frame 3, handle 2 will be clamped and limited to the inner wall of the limiting frame 3. At the same time, under the action of the limiting block 4 and the torsion spring device, handle 2 will be in the current state of rotating 90 degrees counterclockwise.
[0042] When the drainage well cover 1 is disassembled, the worker presses the handle 2 to move it to the position of the limiting frame 3. At this time, a certain magnetic repulsion force is generated between the magnetic block rod 304 and the first magnetic block 306. At the same time, the first spring 305 is compressed to a certain length and generates a corresponding spring force. At this time, the magnetic repulsion force and the spring force are greater than the corresponding clamping force generated by the torsion spring device and the limiting block 4. Therefore, under the action of the magnetic repulsion force between the magnetic block rod 304 and the first magnetic block 306 and the spring of the first spring 305, the limiting frame 3 drives the handle 2 to disengage from the inner wall of the limiting groove 104. The handle 2 tilts out of the interior of the limiting groove 104 to facilitate the worker to open and disassemble the drainage well cover 1.
[0043] Step 2: When handle 2 is inserted into the limiting frame 3, handle 2 squeezes the limiting block 4, thereby driving the limiting block 4 to squeeze the U-shaped plate 402 and the limiting plate 403, thereby driving the locking block 405 to be inserted into the slot inside the drainage well cover 1, so as to help limit the drainage well cover 1 to the inner side of the well frame 101, and further enhance the stability of the drainage well cover 1 and the well frame 101.
