Description

Technical Field

[0001] This invention relates to the field of drainage well cover technology, specifically to an impact-resistant and buffered drainage well cover and its working method. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] Chinese patent CN212052891U discloses an impact-resistant manhole cover, including a manhole cover plate and a manhole cover base. The buffer and shock absorption assembly includes a sliding column, a top cover, a fixing box, a fixing rod, a first return spring, a fixing cylinder, a first pressure block, and a second pressure block. This patent, through the design of the buffer and shock absorption assembly, achieves the absorption of the impact force of the manhole cover by the second pressure block sliding down and pressing tightly against the first pressure block, and the compression of the first return spring. Compared with traditional manhole covers, this manhole cover has better impact resistance, extends its service life, and has lower noise when subjected to impact.

[0004] The impact-resistant manhole cover of the above patent cannot guarantee structural safety during actual use. Under pressure, it is prone to deformation during long-term use, which affects its long-term use. Therefore, it does not meet the existing needs. In response, we propose an impact-resistant buffer drainage manhole cover and its working method. Summary of the Invention

One side of the first manhole cover and one side of the second manhole cover are each provided with a through hole, and the telescopic threaded rod passes through the through hole and is threadedly connected to the first manhole cover and the second manhole cover respectively.

[0012] Preferably, a sealing strip for sealing the gap is provided between the first manhole cover plate and the second manhole cover plate. A partition block is provided at the lower end of the sealing strip. The partition block is embedded in one side of the impact-resistant clamping plate and is sealed to the impact-resistant clamping plate, the first manhole cover plate and the second manhole cover plate respectively. The outer surface of the impact-resistant clamping plate is covered with a layer of anti-corrosion sealing gasket. The impact-resistant clamping plate is sealed to the first manhole cover plate and the second manhole cover plate through the anti-corrosion sealing gasket.

[0013] Preferably, the first manhole cover plate and the second manhole cover plate are provided with an integrally formed positioning and mounting groove at the upper and lower ends of one side. The side pressure plate and the fastening positioning plate are embedded in the positioning and mounting groove and engaged with the first manhole cover plate and the second manhole cover plate. A locking nut is installed at the upper end of the side pressure plate, and a positioning threaded rod is welded to the lower end of the locking nut. The positioning threaded rod passes through the side pressure plate and the fastening positioning plate and is threadedly connected to the fastening positioning plate and the side pressure plate respectively.

[0014] Preferably, the impact-resistant clamp is provided with a limiting groove inside, and the fastening fixing plate is engaged with the impact-resistant clamp through the limiting groove. A reinforcing rib runs through the inside of the limiting groove, and the reinforcing rib runs through the inside of the two fastening fixing plates and is fixedly connected to the two fastening fixing plates.

[0015] Preferably, the upper and lower sides of the impact-resistant clamp are provided with integrally formed sliding grooves. The telescopic column is slidably connected to the impact-resistant clamp through the sliding grooves. The upper and lower ends of the telescopic column are equipped with pneumatic cylinders. The pneumatic cylinders are surrounded by pressure springs, and the two ends of the pneumatic cylinders and pressure springs are fixedly connected to the impact-resistant clamp and the telescopic column, respectively.

[0016] Preferably, the telescopic threaded rod passes through the mounting sleeve and is slidably connected to the mounting sleeve. An adjusting nut is installed in the middle of the mounting sleeve. The adjusting nut is rotatably connected to the mounting sleeve through a bearing. The telescopic threaded rod passes through the adjusting nut and is threadedly connected to the adjusting nut. A threaded sleeve is provided at the rear end of the mounting sleeve, which is used to connect another set of telescopic threaded rods.

[0017] A method for using an impact-resistant and buffer-type drainage well cover includes the following steps:

[0018] Step 1: During installation, connect the connecting shaft at the outer end of the first and second manhole cover plates to the pipeline, and seal the outer ring of the manhole cover by installing a sealing ring around the pipeline;

[0019] Step 2: Close the first manhole cover and the second manhole cover, and insert the impact-resistant clamping plate into the gap between the first manhole cover and the second manhole cover. After the fastening positioning plate is located on the lower end face of the manhole cover, rotate the impact-resistant clamping plate 90 degrees so that the positions of the side pressure plate and the fastening positioning plate correspond to the positions of the positioning installation groove. Then install the locking nut and the positioning threaded rod.

[0020] Step 3: By tightening the positioning threaded rod, the side pressure plate and the fastening positioning plate are embedded into the positioning installation groove. The upper and lower ends of the telescopic column squeeze the air cylinder and pressure spring, which shortens the impact-resistant clamping plate and fixes the position between the first manhole cover plate and the second manhole cover plate.

[0021] Step 4: Install a sealing strip on the outside of the gap, and seal the first manhole cover and the second manhole cover by embedding the spacer block into the side of the impact-resistant plate;

[0022] Step 5: After sealing, rotate the adjusting nut to allow the telescopic threaded rod above the first manhole cover to pass through the first manhole cover and the sealing strip and extend into the interior of the second manhole cover. Fix the other end of the telescopic threaded rod with a threaded sleeve.

[0023] Step Six: After installation, the manhole cover is put into use. When subjected to pressure impact, the first manhole cover plate and the second manhole cover plate are buffered by the impact-resistant clamp.

[0024] Step 7: When drainage is required, remove the sealing strip, unscrew the telescopic threaded rod, retract the telescopic threaded rod into the installation sleeve, then remove the locking nut and the positioning threaded rod, and remove the impact-resistant clamp to drain the water.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention, during installation, involves closing the first and second manhole cover plates and inserting an impact-resistant clamping plate into the gap between them. After the fixing plate is positioned at the lower end of the manhole cover, the impact-resistant clamping plate is rotated 90 degrees to align the positions of the side pressure plate and the fixing plate with the positioning groove. A locking nut and a positioning threaded rod are then installed, allowing the side pressure plate and the fixing plate to embed into the positioning groove. The upper and lower ends of the telescopic column compress the pneumatic cylinder and pressure spring, shortening the impact-resistant clamping plate and fixing the position between the first and second manhole cover plates, thus sealing them. The stable impact-resistant clamping plate ensures that even under high pressure, the first and second manhole cover plates remain stationary due to the parallel arrangement of the impact-resistant clamping plates. The telescopic column inside the impact-resistant clamping plate buffers the pressure, and the pressure is released by the pneumatic cylinder and pressure spring, improving stability.

[0027] 2. This invention involves installing mounting sleeves on the upper surfaces of the first and second manhole cover plates. Under long-term pressure, the telescopic threaded rod above the first manhole cover plate can be extended through the first manhole cover plate and the sealing strip to the interior of the second manhole cover plate by rotating the adjusting nut. The other end of the telescopic threaded rod is fixed by the threaded sleeve, thereby reinforcing the position of the first and second manhole cover plates. Multiple sets of mounting sleeves, in conjunction with a relative number of impact-resistant clamps, improve stability and facilitate disassembly and assembly for drainage and maintenance, making it convenient to use.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To address the issue that existing impact-resistant manhole cover structures cannot guarantee safety and are prone to deformation under pressure during long-term use, thus affecting their longevity, please refer to [the relevant documentation / reference]. Figure 1 - Figure 3 This embodiment provides the following technical solution:

[0038] An impact-resistant and buffer drainage manhole cover includes a first manhole cover plate 1 and a second manhole cover plate 2. The second manhole cover plate 2 is disposed on one side of the first manhole cover plate 1. A gap is provided between the first manhole cover plate 1 and the second manhole cover plate 2. The purpose of the gap is to ensure that there is space between the first manhole cover plate 1 and the second manhole cover plate 2 for the insertion of an impact-resistant clamping plate 5. The lower end surfaces of the first manhole cover plate 1 and the second manhole cover plate 2 are provided with an integrally formed reinforcing plate 102. The bottom strength of the drainage manhole cover can be improved by the reinforcing plate 102.

[0039] Also includes:

[0040] The impact-resistant clamp 5 is set inside the gap. The impact-resistant clamp 5 with stable strength fixes the position between the first manhole cover 1 and the second manhole cover 2. The upper two sides of the impact-resistant clamp 5 are provided with integrally formed side pressure plates 504, and the lower two sides of the impact-resistant clamp 5 are installed with fastening positioning plates 502. The fastening positioning plates 502 and the side pressure plates 504 are used to fix the first manhole cover 1 and the second manhole cover 2. Even when the first manhole cover 1 and the second manhole cover 2 are subjected to high pressure, they can still be limited by the parallel impact-resistant clamp 5. The impact-resistant clamp 5 will be subjected to pressure buffering to improve the stability effect.

[0041] The mounting sleeve 6 is used to connect the first manhole cover plate 1 and the second manhole cover plate 2. Two sets of mounting sleeves 6 are provided, and the two sets of mounting sleeves 6 are fixedly installed on the top of the first manhole cover plate 1 and the second manhole cover plate 2 respectively. The inside of the mounting sleeve 6 is equipped with a telescopic threaded rod 602. The two sets of mounting sleeves 6 are in opposite positions, which makes the movement of the telescopic threaded rod 602 more convenient. The telescopic threaded rod 602 is used to fix the two sets of mounting sleeves 6. The telescopic threaded rod 602 can be rotated to insert and fix the two sets of mounting sleeves 6, thereby improving the efficiency of the installation work.

[0042] One side of the first manhole cover 1 and the second manhole cover 2 is provided with an integrally formed connecting collar 101. A connecting shaft 3 passes through the inside of the connecting collar 101. By rotating the connecting shaft 3, the connecting collar 101 can be rotated, thereby opening or closing the first manhole cover 1 and the second manhole cover 2 to carry out different operations. The first manhole cover 1 and the second manhole cover 2 are rotatably connected to the pipeline through the connecting shaft 3.

[0043] The working principle of the above is as follows: By operating the first manhole cover plate 1 and the second manhole cover plate 2 to close, and inserting the impact-resistant clamping plate 5 into the gap between the first manhole cover plate 1 and the second manhole cover plate 2, after the fastening positioning plate 502 is located on the lower end face of the manhole cover, rotate the impact-resistant clamping plate 5 ninety degrees so that the positions of the side pressure plate 504 and the fastening positioning plate 502 correspond to the positions of the positioning installation groove 104. Then install the locking nut 501 and the positioning threaded rod 503, so that the side pressure plate 504 and the fastening positioning plate 502 can be embedded in the positioning installation groove 104, and the impact-resistant clamping plate 5 shortens, thereby fixing the position between the first manhole cover plate 1 and the second manhole cover plate 2.

[0044] To address the technical problem that existing drainage well covers, with their simple structure, cannot withstand high-pressure environments, thus affecting long-term use, please refer to [the relevant documentation / reference]. Figure 1 - Figure 3 , Figure 6 - Figure 7 The following technical solutions are provided:

[0045] The upper surfaces of the first manhole cover plate 1 and the second manhole cover plate 2 are each provided with an integrally formed fixing groove 103. The fixing groove 103 is used to install the mounting sleeve 6. When the manhole cover needs to be reinforced, the first manhole cover plate 1 and the second manhole cover plate 2 are fixed by the fixing mounting sleeve 6 to improve the strength of the drainage manhole cover and adapt to the long-term pressure environment. One side of the first manhole cover plate 1 and the second manhole cover plate 2 are provided with through holes 105. The telescopic threaded rod 602 passes through the through holes 105 and is threadedly connected to the first manhole cover plate 1 and the second manhole cover plate 2 respectively. The telescopic threaded rod 602 can be quickly adjusted to facilitate fixing and disassembly. Multiple sets of mounting sleeves 6, together with a relative number of impact-resistant clamps 5, further improve stability and facilitate disassembly and assembly for drainage and maintenance work, making it convenient to use.

[0046] A sealing strip 4 for sealing the gap is provided between the first manhole cover plate 1 and the second manhole cover plate 2. A partition block 401 is provided at the lower end of the sealing strip 4. The partition block 401 is embedded in one side of the impact-resistant clamping plate 5 and is sealed to the impact-resistant clamping plate 5, the first manhole cover plate 1 and the second manhole cover plate 2 respectively. By using partition blocks 401 corresponding in number to the impact-resistant clamping plate 5, the sealing work can be carried out with the smallest volume, adapting to different installation environments and improving the work quality. The outer surface of the impact-resistant clamping plate 5 is covered with a layer of anti-corrosion sealing gasket 505. The anti-corrosion sealing gasket 505 deforms after being squeezed with the sealing strip 4, maintaining a tight fit and improving the sealing effect to adapt to long-term pipeline sealing work. The impact-resistant clamping plate 5 is sealed to the first manhole cover plate 1 and the second manhole cover plate 2 through the anti-corrosion sealing gasket 505.

[0047] The telescopic threaded rod 602 passes through the mounting sleeve 6 and is slidably connected to the mounting sleeve 6. An adjusting nut 601 is installed in the middle of the mounting sleeve 6. The adjusting nut 601 is rotatably connected to the mounting sleeve 6 through a bearing. The telescopic threaded rod 602 passes through the adjusting nut 601 and is threadedly connected to the adjusting nut 601. A threaded sleeve 603 is provided at the rear end of the mounting sleeve 6. The threaded sleeve 603 is used to connect another set of telescopic threaded rods 602.

[0048] The working principle of the above is as follows: A sealing strip 4 is installed on the outside of the gap. The first manhole cover 1 and the second manhole cover 2 are sealed by embedding the partition block 401 into the side of the impact-resistant clamping plate 5. The sleeve 6 is installed on the upper end of the first manhole cover 1 and the second manhole cover 2. Under long-term pressure, the telescopic threaded rod 602 above the first manhole cover 1 can be extended through the through hole 105 through the first manhole cover 1 and the sealing strip 4 to the inside of the second manhole cover 2 by rotating the adjusting nut 601. The other end of the telescopic threaded rod 602 is fixed by the threaded sleeve 603, thereby reinforcing the position of the first manhole cover 1 and the second manhole cover 2.

[0049] To address the technical problem in existing technologies where impact-resistant structures are inconvenient to install in drainage well covers, hindering installation and operation, please refer to [reference needed]. Figure 1 , Figure 3 - Figure 5 The following technical solutions are provided:

[0050] The first manhole cover 1 and the second manhole cover 2 are both provided with an integrally formed positioning and mounting groove 104 at the upper and lower ends of one side. The side pressure plate 504 and the fastening positioning plate 502 are embedded in the positioning and mounting groove 104 and engaged with the first manhole cover 1 and the second manhole cover 2. Through the multiple anti-impact clamps 5 arranged in parallel, the first manhole cover 1 and the second manhole cover 2 can still be limited by the parallel anti-impact clamps 5 even when subjected to high pressure. The upper end of the side pressure plate 504 is equipped with a locking nut 501, and the lower end of the locking nut 501 is welded to a positioning threaded rod 503. The positioning threaded rod 503 passes through the side pressure plate 504 and the fastening positioning plate 502 and is threadedly connected to the fastening positioning plate 502 and the side pressure plate 504 respectively. The fastening positioning plate 502 and the side pressure plate 504 at the corresponding positions facilitate the fixing and connection work, making the operation convenient.

[0051] The impact-resistant clamping plate 5 has a limiting groove 507 inside. The fastening fixing plate 502 is engaged with the impact-resistant clamping plate 5 through the limiting groove 507. The limiting groove 507 improves the fixing effect of the fastening fixing plate 502. A reinforcing rib 5021 runs through the inside of the limiting groove 507. The reinforcing rib 5021 runs through the inside of the two fastening fixing plates 502 and is fixedly connected to the two fastening fixing plates 502. When under pressure, the stress provided by the reinforcing rib 5021 keeps the position of the two fastening fixing plates 502 balanced and stable.

[0052] The impact-resistant clamping plate 5 has integrally formed sliding grooves 508 at both the upper and lower parts. The telescopic column 506 is slidably connected to the impact-resistant clamping plate 5 through the sliding grooves 508. The upper and lower ends of the telescopic column 506 are equipped with pneumatic cylinders 5061. The pneumatic cylinders 5061 are surrounded by pressure springs 5062. The two ends of the pneumatic cylinders 5061 and the pressure springs 5062 are fixedly connected to the impact-resistant clamping plate 5 and the telescopic column 506, respectively. The elastic impact-resistant clamping plate 5 can automatically separate the fixed positioning plate 502 and the side pressure plate 504 from the limiting groove 507, which can facilitate disassembly.

[0053] The working principle of the above is as follows: Close the first manhole cover plate 1 and the second manhole cover plate 2, and insert the impact-resistant clamping plate 5 into the gap between the first manhole cover plate 1 and the second manhole cover plate 2. After the fastening positioning plate 502 is located on the lower end face of the manhole cover, rotate the impact-resistant clamping plate 5 ninety degrees so that the positions of the side pressure plate 504 and the fastening positioning plate 502 correspond to the positions of the positioning installation groove 104. Then install the locking nut 501 and the positioning threaded rod 503. By tightening the positioning threaded rod 503, the side pressure plate 504 and the fastening positioning plate 502 are embedded in the positioning installation groove 104. The upper and lower ends of the telescopic column 506 squeeze the air cylinder 5061 and the pressure spring 5062, which shortens the impact-resistant clamping plate 5 and fixes the position between the first manhole cover plate 1 and the second manhole cover plate 2.

[0054] Please see Figure 1- Figure 7 A method for using an impact-resistant and buffer drainage well cover includes the following steps:

[0055] Step 1: During installation, connect the connecting shaft 3 at the outer end of the first manhole cover plate 1 and the second manhole cover plate 2 to the pipeline. Seal the outer ring of the manhole cover by installing a sealing ring around the pipeline. By rotating the connecting shaft 3, the connecting collar 101 can be rotated, thereby opening or closing the first manhole cover plate 1 and the second manhole cover plate 2.

[0056] Step 2: Close the first manhole cover plate 1 and the second manhole cover plate 2, and insert the impact-resistant clamping plate 5 into the gap between the first manhole cover plate 1 and the second manhole cover plate 2. After the fastening positioning plate 502 is located on the lower end face of the manhole cover, rotate the impact-resistant clamping plate 5 ninety degrees to facilitate quick insertion into the gap for positioning, so as to facilitate subsequent operations. After the positions of the side pressure plate 504 and the fastening positioning plate 502 correspond to the positions of the positioning installation groove 104, install the locking nut 501 and the positioning threaded rod 503.

[0057] Step 3: By tightening the positioning threaded rod 503, the side pressure plate 504 and the fastening positioning plate 502 are embedded into the positioning mounting groove 104. The upper and lower ends of the telescopic column 506 squeeze the air cylinder 5061 and the pressure spring 5062, which shortens the impact-resistant clamping plate 5 and fixes the position between the first manhole cover plate 1 and the second manhole cover plate 2. The pressure can be buffered by the telescopic column 506 inside the impact-resistant clamping plate 5, and the pressure can be released by the air cylinder 5061 and the pressure spring 5062 to improve the stability effect.

[0058] Step 4: Install sealing strip 4 on the outside of the gap, and seal the first manhole cover 1 and the second manhole cover 2 by embedding the partition block 401 into the side of the impact-resistant clamping plate 5.

[0059] Step 5: After sealing, rotate the adjusting nut 601 to allow the telescopic threaded rod 602 above the first manhole cover plate 1 to pass through the first manhole cover plate 1 and the sealing strip 4 and extend into the interior of the second manhole cover plate 2. Fix the other end of the telescopic threaded rod 602 with the threaded sleeve 603, and fix the first manhole cover plate 1 and the second manhole cover plate 2 with the fixing sleeve 6 to improve the strength of the drainage manhole cover to adapt to the long-term pressure environment.

[0060] Step Six: After installation, the manhole cover is used. When subjected to pressure impact, the first manhole cover plate 1 and the second manhole cover plate 2 are buffered by the impact-resistant clamping plate 5. Through the multiple impact-resistant clamping plates 5 arranged in parallel, the first manhole cover plate 1 and the second manhole cover plate 2 can still be limited by the parallel impact-resistant clamping plates 5 even when subjected to high pressure.

[0061] Step 7: When drainage is required, remove the sealing strip 4, unscrew the telescopic threaded rod 602, and retract the telescopic threaded rod 602 into the mounting sleeve 6. Then, remove the locking nut 501 and the positioning threaded rod 503, and remove the impact-resistant clamping plate 5. The elastic impact-resistant clamping plate 5 can automatically separate the fixed positioning plate 502 and the side pressure plate 504 from the limiting groove 507, so that the impact-resistant clamping plate 5 can be easily removed for drainage.

[0062] Working principle: During installation, connect the connecting shaft 3 at the outer ends of the first manhole cover plate 1 and the second manhole cover plate 2 to the pipeline. Seal the outer ring of the manhole cover by installing a sealing ring around the pipeline to close the first manhole cover plate 1 and the second manhole cover plate 2. Insert the impact-resistant clamping plate 5 into the gap between the first manhole cover plate 1 and the second manhole cover plate 2. After the fastening positioning plate 502 is located on the lower end face of the manhole cover, rotate the impact-resistant clamping plate 5 90 degrees so that the positions of the side pressure plate 504 and the fastening positioning plate 502 correspond to the positions of the positioning installation groove 104. Then install the locking nut 501 and the positioning threaded rod 503. Tighten the positioning threaded rod 503 to make the side pressure plate 504 and the fastening positioning plate 502 correspond to the positions of the positioning installation groove 104. Plate 502 is embedded in the positioning mounting groove 104. The upper and lower ends of the telescopic column 506 compress the air cylinder 5061 and pressure spring 5062, shortening the impact-resistant clamping plate 5 and fixing the position between the first manhole cover plate 1 and the second manhole cover plate 2. After fixing, a sealing strip 4 is installed on the outside of the gap. The first manhole cover plate 1 and the second manhole cover plate 2 are sealed by the partition pad 401 embedded in the side of the impact-resistant clamping plate 5. The mounting sleeve 6 is installed on the upper end of the first manhole cover plate 1 and the second manhole cover plate 2. Under long-term pressure, the telescopic threaded rod 602 above the first manhole cover plate 1 can pass through the through hole 105 by rotating the adjusting nut 601. The manhole cover plate 1 and sealing strip 4 extend into the interior of the second manhole cover plate 2. The other end of the telescopic threaded rod 602 is fixed by a threaded sleeve 603, reinforcing the position of the first manhole cover plate 1 and the second manhole cover plate 2. When reinforcement of the manhole cover is required, the first manhole cover plate 1 and the second manhole cover plate 2 are fixed by a fixing sleeve 6, improving the strength of the drainage manhole cover to withstand long-term pressure. Multiple sets of fixing sleeves 6, combined with a relatively large number of impact-resistant clamps 5, further improve stability and facilitate disassembly and assembly for drainage and maintenance. The multiple impact-resistant clamps 5 arranged side-by-side ensure that even if the first manhole cover plate 1 and the second manhole cover plate 2 are subjected to pressure... Under high pressure, the parallel-arranged impact-resistant clamps 5 can still limit the movement. The telescopic column 506 inside the impact-resistant clamps 5 can buffer the pressure. The pressure is released by the pneumatic cylinder 5061 and the pressure spring 5062 to improve the stability. After installation, the manhole cover is used. When subjected to pressure impact, the first manhole cover 1 and the second manhole cover 2 are buffered by the impact-resistant clamps 5. When drainage is required, the sealing strip 4 is removed, the telescopic threaded rod 602 is unscrewed, and the telescopic threaded rod 602 is retracted into the installation sleeve 6.
