Description

Technical Field

[0001] The utility model relates to the technical field of hidden manhole covers, in particular to a lawn surface hidden manhole cover. Background Art

[0002] There will be relatively many underground pipes in the construction of parks. These pipes must have an outlet leading to the ground at intervals. The section from the pipe to the ground is called a manhole. The manhole opening is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the existing manhole covers need to be opened, they need to be pried open with tools. During this process, the operation is difficult and bumps are prone to occur during the process of prying them open with tools, which in turn causes damage to the surface of the manhole cover, thereby affecting the aesthetics of the manhole cover. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a lawn surface hidden manhole cover.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a lawn surface hidden manhole cover, including the ground, the upper surface of the ground is provided with a manhole opening, a manhole cover is installed on the wellhead, the upper surface of the manhole cover is flush with the ground, a plurality of water leakage holes are opened through the upper surface of the manhole cover, a fixing component for fixing the manhole cover is arranged on the manhole cover, and a switch component for closing the fixing component is arranged on the manhole cover.

[0006] By adopting the above technical solution, when the staff needs to install the manhole cover, the staff needs to start the fixing component, and then the manhole cover is installed in the wellhead under the action of the fixing component. In addition, when the staff needs to open the manhole cover, the staff needs to start the switch component, and then the fixing component is closed under the action of the switch component. In this process, there is no need to use tools to open and close the manhole cover, thereby reducing the probability of the manhole cover being bumped, thereby improving the aesthetics of the manhole cover.

[0007] Furthermore, a fixing groove is provided on the inner wall of the wellhead, and the fixing assembly includes a plurality of rotating blocks distributed in an array on the bottom surface of the well cover, a plurality of rotating rods rotatably arranged on the side walls of the plurality of rotating blocks, a plurality of fixed blocks respectively fixedly arranged on the bottom surfaces of the plurality of rotating rods, and a plurality of first springs respectively fixedly arranged on the upper surfaces of the plurality of rotating rods, the other ends of the plurality of first springs are respectively fixedly arranged on the bottom surface of the well cover, the plurality of fixed blocks are all engaged with the fixing grooves, and the cross-section of the rotating rod is L-shaped.

[0008] By adopting the above technical solution, when the staff needs to install the manhole cover, the staff needs to make the manhole cover face the wellhead. Then, the staff needs to move the manhole cover downward, so that the fixing assembly moves downward under the action of the manhole cover. At this time, when the fixed block abuts against the inner wall of the wellhead, the rotating rod rotates, so that the fixed block rotates under the action of the rotating rod. In this process, when the fixed block faces the fixed groove, the rotating rod rotates in the opposite direction under the action of the first spring, so that the fixed block rotates in the opposite direction under the action of the rotating rod, so that the upper surface of the fixed block abuts against the inner top wall of the fixed groove. At this time, when the staff moves the manhole cover upward, the upper surface of the fixed block abuts against the inner top wall, so that the staff cannot open the manhole cover, thereby improving the safety of the manhole cover.

[0009] Furthermore, a receiving groove is provided on the upper surface of the manhole cover, a sliding groove is provided through the inner bottom wall of the receiving groove, and the switch assembly includes a sliding rod slidably set in the sliding groove, a mounting plate fixedly set on the bottom surface of the sliding rod, and a blocking plate fixedly set on the upper surface of the sliding rod, and the blocking plate is slidably connected to the receiving groove.

[0010] By adopting the above technical solution, when the staff needs to open the manhole cover, the staff needs to slide the blocking plate upwards, and then the sliding rod slides upwards under the action of the blocking plate, so that the mounting plate slides upwards under the action of the sliding rod, and then the upper surface of the mounting plate abuts against the rotating rod, so that the rotating rod rotates under the action of the mounting plate, and then the fixed block rotates under the action of the rotating rod, so that the fixed block and the fixed groove are separated from each other. In this process, when the mounting plate abuts against the manhole cover, the manhole cover moves upwards under the action of the mounting plate, thereby reducing the difficulty of opening the manhole cover for the staff.

[0011] Furthermore, a U-shaped groove is provided on the upper surface of the blocking plate, and reset grooves are provided on two opposite inner walls of the U-shaped groove. A rotating handle with a U-shaped cross-section is rotatably arranged in the U-shaped groove, and torsion springs are fixedly arranged on two opposite side walls of the rotating handle, and the other ends of the two torsion springs are respectively fixedly arranged on the inner walls of the two reset grooves that are away from each other.

[0012] By adopting the above technical solution, when the staff needs to slide the blocking plate upward, the staff needs to turn the rotating handle so that the rotating handle and the manhole cover are perpendicular to each other. At this time, the staff needs to lift the rotating handle upward, so that the blocking plate slides upward under the action of the rotating handle, so that the slide bar slides upward under the action of the blocking plate, and then the installation plate slides upward under the action of the slide bar, thereby reducing the difficulty of the staff to slide the blocking plate, thereby reducing the difficulty of the staff's work.

[0013] Furthermore, a first inclined surface is formed on the edges where the bottom surfaces of the plurality of fixing blocks intersect with the side walls thereof away from the sliding rod.

[0014] By adopting the above technical solution, when the fixing block rotates under the action of the rotating rod, the first inclined surface reduces the probability of the fixing block and the fixing groove being engaged, thereby improving the stability of the device.

[0015] Furthermore, blocking blocks are fixedly provided on four opposite inner walls of the wellhead, the side walls of the four blocking blocks that are close to each other abut against each other, and the upper surfaces of the four blocking blocks abut against the bottom surface of the well cover.

[0016] By adopting the above technical solution, when the upper surface of the fixing block abuts against the inner top wall of the fixing groove, the bottom surface of the manhole cover abuts against the upper surface of the blocking block, so that the blocking block blocks the manhole cover, thereby reducing the probability of the manhole cover slipping and improving the stability of the device.

[0017] Furthermore, filter nets are fixedly arranged in the plurality of water leakage holes.

[0018] By adopting the above technical solution, when rainy weather occurs, the filter net filters the debris in the water, thereby reducing the probability of sewer pipe blockage.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to install the manhole cover, the staff needs to start the fixing component, so that the manhole cover is installed in the wellhead under the action of the fixing component. In addition, when the staff needs to open the manhole cover, the staff needs to start the switch component, so that the fixing component is closed under the action of the switch component. In this process, there is no need to use tools to open and close the manhole cover, thereby reducing the probability of the manhole cover being bumped, thereby improving the aesthetics of the manhole cover;

In the present application, when the staff needs to open the manhole cover, the staff needs to slide the blocking plate upwards, thereby causing the slide rod to slide upwards under the action of the blocking plate, thereby causing the mounting plate to slide upwards under the action of the slide rod, thereby causing the upper surface of the mounting plate to abut against the rotating rod, thereby causing the rotating rod to rotate under the action of the mounting plate, thereby causing the fixed block to rotate under the action of the rotating rod, thereby separating the fixed block and the fixed groove from each other. During this process, when the mounting plate abuts against the manhole cover, the manhole cover moves upwards under the action of the mounting plate, thereby reducing the difficulty for the staff to open the manhole cover.

[0028] like Figure 1-3 As shown, the embodiment of the present application discloses a lawn surface hidden manhole cover, including a ground 1, a manhole cover 11, a manhole opening 2, a fixing assembly 3, a switch assembly 4, a rotating handle 5, a torsion spring 51 and a blocking block 7. A manhole opening 2 is provided on the upper surface of the ground 1, and the manhole cover 11 is a rectangular plate-shaped structure. The manhole cover 11 is installed on the manhole opening 2, and the upper surface of the manhole cover 11 is flush with the ground 1, and a plurality of water leakage holes 21 are provided through the upper surface of the manhole cover 11.

[0029] When the staff needs to install the manhole cover 11, the staff needs to start the fixing component 3, so that the manhole cover 11 is installed in the manhole 2 under the action of the fixing component 3. In addition, when the staff needs to open the manhole cover 11, the staff needs to start the switch component 4, so that the fixing component 3 is closed under the action of the switch component 4. In this process, there is no need to use tools to open and close the manhole cover 11, thereby reducing the probability of the manhole cover 11 being bumped, thereby improving the aesthetics of the manhole cover 11.

[0030] The fixing assembly 3 is arranged on the manhole cover 11 and is used to fix the manhole cover 11. The fixing assembly 3 includes a rotating block 31, a rotating rod 32, a fixing block 33 and a first spring 34. The rotating block 31 is a rectangular block structure.

A plurality of rotating rods 32 are provided and are rotatably arranged on the side walls of the plurality of rotating blocks 31. The fixing block 33 is a rectangular block structure. A plurality of fixing blocks 33 are provided and are fixedly arranged on the bottom surfaces of the plurality of rotating rods 32, and the plurality of fixing blocks 33 are all engaged with the fixing groove 22. A plurality of first springs 34 are provided, one end of the plurality of first springs 34 is fixedly arranged on the upper surfaces of the plurality of rotating rods 32, and the other ends of the plurality of first springs 34 are fixedly arranged on the bottom surface of the manhole cover 11.

[0031] When the staff needs to install the manhole cover 11, the staff needs to make the manhole cover 11 face the wellhead 2. Then, the staff needs to move the manhole cover 11 downward, so that the fixing assembly 3 moves downward under the action of the manhole cover 11. At this time, when the fixing block 33 abuts against the inner wall of the wellhead 2, the rotating rod 32 rotates, so that the fixing block 33 rotates under the action of the rotating rod 32. In this process, when the fixing block 33 faces the fixing groove 22, the rotating rod 32 rotates in the opposite direction under the action of the first spring 34, so that the fixing block 33 rotates in the opposite direction under the action of the rotating rod 32, so that the upper surface of the fixing block 33 abuts against the inner top wall of the fixing groove 22. At this time, when the staff moves the manhole cover 11 upward, the upper surface of the fixing block 33 abuts against the inner top wall, so that the staff cannot open the manhole cover 11, thereby improving the safety of the manhole cover 11.

[0032] The upper surface of the manhole cover 11 is provided with a receiving groove 23, and the inner bottom wall of the receiving groove 23 is penetrated with a sliding groove 24.

The blocking plate 43 is a rectangular plate-shaped structure, and the blocking plate 43 is fixedly arranged on the upper surface of the slide bar 41, and the blocking plate 43 is slidably connected with the receiving groove 23.

[0033] When the staff needs to open the manhole cover 11, the staff needs to slide the blocking plate 43 upwards, so that the sliding rod 41 slides upwards under the action of the blocking plate 43, so that the mounting plate 42 slides upwards under the action of the sliding rod 41, and then the upper surface of the mounting plate 42 abuts against the rotating rod 32, so that the rotating rod 32 rotates under the action of the mounting plate 42, and then the fixing block 33 rotates under the action of the rotating rod 32, so that the fixing block 33 and the fixing groove 22 are separated from each other. In this process, when the mounting plate 42 abuts against the manhole cover 11, the manhole cover 11 moves upwards under the action of the mounting plate 42, thereby reducing the difficulty of opening the manhole cover 11 for the staff.

[0034] A U-shaped groove 25 is formed on the upper surface of the blocking plate 43, and reset grooves 26 are formed on two opposite inner walls of the U-shaped groove 25. The cross section of the rotating handle 5 is U-shaped, and the rotating handle 5 is rotatably arranged in the U-shaped groove 25. Two torsion springs 51 are provided, and one end of the two torsion springs 51 is respectively fixedly arranged on two opposite side walls of the rotating handle 5, and the other ends of the two torsion springs 51 are respectively fixedly arranged on the inner walls of the two reset grooves 26 that are away from each other.

[0035] When the staff needs to slide the blocking plate 43 upward, the staff needs to rotate the rotating handle 5, so that the rotating handle 5 and the manhole cover 11 are perpendicular to each other. At this time, the staff needs to lift the rotating handle 5 upward, so that the blocking plate 43 slides upward under the action of the rotating handle 5, so that the slide bar 41 slides upward under the action of the blocking plate 43, and then the mounting plate 42 slides upward under the action of the slide bar 41, thereby reducing the difficulty of sliding the blocking plate 43 for the staff, thereby reducing the difficulty of the staff's work.

[0036] A first inclined surface 6 is formed on the edges where the bottom surfaces of the plurality of fixing blocks 33 intersect with the side walls thereof away from the sliding rod 41 .

[0037] When the fixing block 33 rotates under the action of the rotating rod 32 , the first inclined surface 6 reduces the probability of the fixing block 33 being engaged with the fixing groove 22 , thereby improving the stability of the device.

[0038] The blocking block 7 is a rectangular block structure, and four blocking blocks 7 are provided and fixedly arranged on four opposite inner walls of the wellhead 2. The side walls of the four blocking blocks 7 close to each other abut against each other, and the upper surfaces of the four blocking blocks 7 abut against the bottom surface of the well cover 11.

[0039] When the upper surface of the fixing block 33 abuts against the inner top wall of the fixing groove 22, the bottom surface of the manhole cover 11 abuts against the upper surface of the blocking block 7, so that the blocking block 7 blocks the manhole cover 11, thereby reducing the probability of the manhole cover 11 slipping and improving the stability of the device.

[0040] In order to reduce the probability of the sewer pipe being blocked, a filter net 8 is fixedly arranged in each of the plurality of water leakage holes 21. When it rains, the filter net 8 filters the debris in the water, thereby reducing the probability of the sewer pipe being blocked.

Subsequently, the staff needs to move the manhole cover 11 downward, so that the fixing assembly 3 moves downward under the action of the manhole cover 11. At this time, when the fixing block 33 abuts against the inner wall of the wellhead 2, the rotating rod 32 rotates, so that the fixing block 33 rotates under the action of the rotating rod 32. In this process, when the fixing block 33 faces the fixing groove 22, the rotating rod 32 rotates in the opposite direction under the action of the first spring 34, so that the fixing block 33 rotates in the opposite direction under the action of the rotating rod 32, so that the upper surface of the fixing block 33 abuts against the inner top wall of the fixing groove 22. At this time, when the staff moves the manhole cover 11 upward, the upper surface of the fixing block 33 abuts against the inner top wall, so that the staff cannot open the manhole cover 11, thereby improving the safety of the manhole cover 11. In addition, when the staff needs to open the manhole cover 11, the staff needs to start the switch assembly 4, and the staff needs to slide the blocking plate 43 upward, so that the sliding rod 41 slides upward under the action of the blocking plate 43, so that the mounting plate 42 slides upward under the action of the sliding rod 41, and then the upper surface of the mounting plate 42 abuts against the rotating rod 32, so that the rotating rod 32 rotates under the action of the mounting plate 42, and then the fixing block 33 rotates under the action of the rotating rod 32, so that the fixing block 33 and the fixing groove 22 are separated from each other.
