Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, specifically a splicing invisible manhole cover. Background Technology

[0002] Manhole covers are the sealing structures at the top of entrances to underground facilities. They are required wherever public utilities such as water supply, telecommunications, electricity, gas, heating, fire protection, and sanitation are installed. With my country's rapid economic development, infrastructure construction has entered a new cycle, resulting in a huge market demand for manhole covers in urban planning and road construction. Manhole covers are categorized into ordinary exposed manhole covers, such as cast iron round manhole covers, and integrated concealed manhole covers.

[0003] Chinese Utility Model Patent Publication No. CN216156643U discloses a spliced ​​manhole cover. The specification of this spliced ​​manhole cover states that by defining the positions of the anti-detachment blocks in four directions, the inner ring, outer ring, and inner cover are connected to form a complete manhole cover structure. When disassembled, these components function independently. During use, if one part is damaged, it can be replaced selectively, while the remaining parts can continue to be used, thus reducing resource waste and solving the problem of needing to replace the entire manhole cover once damaged, thereby lowering costs. However, this spliced ​​manhole cover lacks a protective structure for the opening, which can easily lead to blockages caused by road debris and dust after prolonged installation. This necessitates cleaning during subsequent maintenance, resulting in low work efficiency and affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a splicing invisible manhole cover, which can effectively solve the problem in the prior art where the protective structure of the opening is not designed, which easily leads to the blockage of the manhole cover due to garbage and dust on the road after a long period of laying. As a result, it needs to be cleaned during subsequent maintenance, which leads to low work efficiency and affects normal use.

[0005] The technical solution adopted by this utility model is: a splicing invisible manhole cover, including a manhole cover frame, angle steel is fixedly installed at the four corners of the manhole cover frame, a reinforcing rib one and a reinforcing rib two are provided on the inner edge of the manhole cover frame, a protective component is inserted and installed on the side of the angle steel away from the manhole cover frame, and a water leakage component is fixedly installed on the outer edge of the manhole cover frame. The protective component includes a positioning block, and an installation block and a limiting block are sequentially fixedly installed on one end of the positioning block near the manhole cover frame; The water-leaking component includes a water-leaking frame, and a connecting groove is provided along the inner edge of the water-leaking frame. A water-leaking cover is snapped onto the water-leaking frame through the connecting groove.

[0006] Preferably, the angle steel has a positioning groove and an installation groove on the side away from the manhole cover frame, the positioning groove being adapted to the positioning block, and the installation groove being adapted to the installation block.

[0007] Through the above technical solution, the design of the positioning block can limit the lateral displacement of the protective component by embedding the positioning block into the positioning groove, and together with the installation block embedded into the installation groove to limit the longitudinal displacement, the two work together to ensure that the protective component fits tightly against the angle steel, avoiding the loosening of the protective component caused by daily pedestrians and vehicles running over it, and preventing dust and garbage from easily clogging the positioning groove and installation groove, which would make it inconvenient to open and close the manhole cover frame later.

[0008] Preferably, the manhole cover frame has a slot at one end near the water leakage component, and a connecting plate is fixedly installed at one end of the water leakage frame, and the slot is adapted to the water leakage frame.

[0009] The above technical solution, through the cooperation of the slot and the drainage frame, not only can it play a role in quick positioning when installing the drainage component, but it can also play a role in limiting the movement to prevent displacement. After positioning is completed, the two can be fixed together by welding, which can not only play a role in drainage, but also reflect its concealment.

[0010] Preferably, the angle steel has a limiting groove on the side away from the manhole cover frame, the positioning block has a reserved hole at the end away from the limiting block, the limiting groove is adapted to the limiting block, the limiting block is a rubber block, and the limiting block and the limiting groove are interference fit.

[0011] The above technical solution uses a rubber limiting block that is interference-fitted into a limiting groove. The elastic deformation of the rubber fills the gap and generates continuous extrusion force, preventing the protective components from shifting during vibration and further improving the overall deformation resistance.

[0012] Preferably, a vertical plate is fixedly installed at the end of the drain frame away from the drain cover, and the vertical plate is located directly below the drain cover.

[0013] Through the above technical solution, the vertical plate design allows the drain cover to withstand the pressure of pedestrians and vehicles for a long time. The vertical plate supports the drain cover from below, preventing it from bending or breaking due to excessive force. After rainwater flows in through the gaps in the drain cover, the vertical plate can guide the water flow to the drainage pipe at the bottom of the well, preventing rainwater from directly impacting the mud or debris at the bottom of the well, and preventing large particles of debris from clogging the pipe.

[0014] Preferably, the manhole cover frame has a first slot and a second slot along its inner edge, the first reinforcing rib being inserted into the first slot, and the second reinforcing rib being inserted into the second slot.

[0015] Through the above technical solution, by cooperating with the first and second slots and the first and second reinforcing ribs, the spacing between the multiple reinforcing ribs can be adjusted according to the actual working conditions during installation, which can avoid the waste of cement blocks. At the same time, it can play a positioning role for the subsequent welding of the first and second reinforcing ribs, thereby improving the construction efficiency.

[0016] Preferably, the first reinforcing rib and the second reinforcing rib are arranged in a cross shape, and a reinforcing plate is fixedly installed at the end of the second reinforcing rib away from the first reinforcing rib. The height of the reinforcing plate is less than the height of the manhole cover frame.

[0017] The above technical solution distributes the load of the manhole cover frame evenly to the four sides of the frame and the bottom support structure through a cross-shaped distribution, avoiding local load concentration. At the same time, the height of the reinforcing plate is lower than that of the manhole cover frame, so that the manhole cover is flush with the ground after installation, which does not affect pedestrians or vehicles, and avoids appearance defects caused by the reinforcing plate protruding.

[0018] Compared with the prior art, this utility model provides a splicing concealed manhole cover, which has the following beneficial effects: 1. This spliced ​​invisible manhole cover, through the design of the positioning block, can limit the lateral displacement of the protective component by embedding the positioning block into the positioning groove, and together with the installation block embedded into the installation groove to limit the longitudinal displacement, the two work together to ensure that the protective component fits the angle steel. Furthermore, the rubber limiting block is interference-fitted into the limiting groove, and the elastic deformation of the rubber fills the gap, generating continuous extrusion force to prevent the protective component from shifting during vibration. This can further improve the overall deformation resistance, prevent the protective component from loosening due to daily pedestrian and vehicle running over it, and prevent dust and garbage from easily clogging the positioning groove and installation groove, which would make it inconvenient for subsequent maintenance of the manhole cover frame. 2. This spliced ​​invisible manhole cover, through the design of the vertical plate, supports the leaking cover from below because the leaking cover bears the pressure of pedestrians and vehicles for a long time. This prevents the leaking cover from bending or breaking due to excessive force. In addition, after rainwater flows in through the gaps of the leaking cover, the vertical plate can guide the water flow to the drainage pipe at the bottom of the manhole, preventing rainwater from directly impacting the mud or debris at the bottom of the manhole, and at the same time preventing large particles of debris from clogging the pipe. 3. This interlocking concealed manhole cover, through the cooperation of slot one and slot two with reinforcing rib one and reinforcing rib two, allows for adjustment of the spacing between multiple reinforcing ribs one and two according to the actual working conditions during installation. This avoids the waste of cement blocks and also provides positioning for the subsequent welding of reinforcing ribs one and two, improving construction efficiency. At the same time, the height of the reinforcing plate is lower than that of the manhole cover frame, so that the manhole cover is flush with the ground after installation, without affecting pedestrians or vehicles, and avoiding appearance defects caused by the reinforcing plate protruding.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-7 As shown, the present invention provides a splicing invisible manhole cover, including a manhole cover frame 1, angle steel 11 fixedly installed at the four corners of the manhole cover frame 1, reinforcing rib 1 8 and reinforcing rib 2 9 provided on the inner edge of the manhole cover frame 1, a protective component 7 inserted and installed on the side of the angle steel 11 away from the manhole cover frame 1, and a water leakage component 13 fixedly installed on the outer edge of the manhole cover frame 1. The protective component 7 includes a positioning block 701, and an installation block 702 and a limiting block 703 are fixedly installed on one end of the positioning block 701 near the manhole cover frame 1. The water leakage component 13 includes a water leakage frame 1301, and a connecting groove 1303 is provided at the inner edge of the water leakage frame 1301. A water leakage cover 1305 is snapped onto the water leakage frame 1301 through the connecting groove 1303.

[0023] Specifically, the side of the angle steel 11 away from the manhole cover frame 1 is provided with a positioning groove 4 and an installation groove 5. The positioning groove 4 is adapted to the positioning block 701, and the installation groove 5 is adapted to the installation block 702. The advantage is that, through the design of the positioning block 701, the lateral displacement of the protective component 7 can be limited by the positioning block 701 being embedded in the positioning groove 4, and the longitudinal displacement can be limited by the installation block 702 being embedded in the installation groove 5. The two work together to ensure that the protective component 7 fits tightly against the angle steel 11, avoiding the loosening of the protective component 7 caused by daily pedestrians and vehicles, and preventing dust and garbage from easily clogging the positioning groove 4 and the installation groove 5, which would make it inconvenient to open and close the manhole cover frame 1 laterally.

[0024] Specifically, a slot 12 is provided at one end of the manhole cover frame 1 near the water leakage component 13, and a connecting plate 1302 is fixedly installed at one end of the water leakage frame 1301. The slot 12 is adapted to the water leakage frame 1301. The advantage is that, through the cooperation of the slot 12 and the water leakage frame 1301, the water leakage component 13 can not only be quickly positioned, but also be limited to prevent displacement. After positioning, the two can be fixed together by welding, which can not only achieve the function of water leakage, but also reflect its concealment.

[0025] Specifically, a limiting groove 6 is provided on the side of the angle steel 11 away from the manhole cover frame 1, and a reserved hole 704 is provided on the end of the positioning block 701 away from the limiting block 703. The limiting groove 6 is adapted to the limiting block 703. The limiting block 703 is a rubber block, and the limiting block 703 and the limiting groove 6 are interference fit. The advantage is that by the rubber limiting block 703 being interference-fitted into the limiting groove 6, the elastic deformation of the rubber is used to fill the gap and generate continuous extrusion force, which prevents the protective component 7 from shifting during vibration and can further improve the overall deformation resistance.

[0026] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, a vertical plate 1304 is fixedly installed at the end of the drain frame 1301 away from the drain cover 1305. The vertical plate 1304 is located directly below the drain cover 1305. The advantage is that, through the design of the vertical plate 1304, since the drain cover 1305 is subjected to the pressure of pedestrians and vehicles for a long time, the vertical plate 1304 supports the drain cover 1305 from below, preventing the drain cover 1305 from bending or breaking due to excessive force. In addition, after rainwater flows in through the gaps of the drain cover 1305, the vertical plate 1304 can guide the water flow to the drainage pipe at the bottom of the well, preventing rainwater from directly impacting the mud or debris at the bottom of the well, and preventing large particles of debris from causing blockage of the pipe.

[0028] Specifically, the inner edge of the manhole cover frame 1 is provided with slot 1 2 and slot 2 3. Reinforcing rib 1 8 is inserted into slot 1 2, and reinforcing rib 2 9 is inserted into slot 2 3. The advantage is that, through the cooperation of slot 1 2 and slot 2 3 with reinforcing rib 1 8 and reinforcing rib 2 9, the spacing between multiple reinforcing ribs 1 8 and reinforcing rib 2 9 can be adjusted according to the actual working conditions during installation, which can avoid the waste of cement blocks. At the same time, it can play a positioning role for the subsequent welding of reinforcing ribs 1 8 and reinforcing rib 2 9, which can improve the construction efficiency.

[0029] Specifically, reinforcing rib 1 8 and reinforcing rib 2 9 are arranged in a cross shape. A reinforcing plate 10 is fixedly installed at the end of reinforcing rib 2 9 away from reinforcing rib 1 8. The height of the reinforcing plate 10 is less than the height of the manhole cover frame 1. The advantage is that the cross-shaped distribution allows the load of the manhole cover frame 1 to be evenly distributed to the four sides of the manhole cover frame 1 and the bottom support structure, avoiding local load concentration. At the same time, the height of the reinforcing plate 10 is lower than that of the manhole cover frame 1, so that the manhole cover is flush with the ground after being laid, which does not affect pedestrians or vehicles. It also avoids appearance defects caused by the reinforcing plate 10 protruding.

[0030] Working Principle: During use, the positioning block 701, when embedded in the positioning groove 4, restricts the lateral displacement of the protective component 7. In conjunction with the mounting block 702 embedded in the mounting groove 5, it restricts longitudinal displacement. Together, they ensure the protective component 7 fits tightly against the angle steel 11, preventing loosening caused by pedestrians and vehicles, and preventing dust and debris from clogging the positioning groove 4 and mounting groove 5, which would hinder the subsequent opening and closing of the manhole cover frame 1. The slot 12, in cooperation with the drain frame 1301, not only provides quick positioning during the installation of the drain component 13 but also acts as a limit, preventing displacement. After positioning, the two can be fixed together by welding, providing both drainage and concealment. The rubber limiting block 703, with its interference fit into the limiting groove 6, fills the gap using the elastic deformation of the rubber, generating continuous compressive force to prevent the protective component 7 from shifting during vibration, further improving overall deformation resistance. The vertical plate 1304, due to the design of the drain cover 130... 5. Bearing the pressure of pedestrians and vehicles for extended periods, the vertical plate 1304 supports the drain cover 1305 from below, preventing it from bending or breaking due to excessive force. After rainwater flows in through the gaps in the drain cover 1305, the vertical plate 1304 guides the water flow towards the drainage pipe at the bottom of the well, preventing rainwater from directly impacting the mud or debris at the bottom of the well. This also prevents large particles from clogging the pipe. Through the cooperation of slots 1 and 2, and reinforcing ribs 1 and 2, the positions can be adjusted according to the actual working conditions during installation. The spacing between multiple reinforcing ribs 1-8 and 2-9 can avoid the waste of cement blocks, and at the same time, it can play a positioning role for the subsequent welding of reinforcing ribs 1-8 and 2-9, which can improve the construction efficiency. The cross-shaped distribution can evenly transfer the load of the manhole cover frame 1 to the four sides of the manhole cover frame 1 and the bottom support structure, avoiding local load concentration. At the same time, the height of the reinforcing plate 10 is lower than that of the manhole cover frame 1, so that the manhole cover is flush with the ground after being laid, which does not affect pedestrians or vehicles, and avoids appearance defects caused by the protrusion of the reinforcing plate 10.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
