Description

Technical Field

[0001] The utility model relates to the technical field of safety protection for sewage wells, and particularly relates to a sewage well anti-falling device for urban safety engineering. Background Art

[0002] A sewage well is what we usually call a sewer manhole, which is an important part of urban safety engineering. It is mainly used for inspecting and cleaning sewer pipes. Generally, a manhole cover is equipped on the upper part of the sewage well. When it is necessary to go down into the pipe for inspection usually, just open the manhole cover. With the frequent occurrence of falling accidents into wells, anti-falling devices have been gradually configured in sewage inspection wells. Most of the anti-falling devices are anti-falling nets or anti-falling plates, which are arranged under the manhole cover so that even if the manhole cover is lost or not covered, people walking will not directly fall into the sewer pipe.

[0003] Currently, the commonly used anti-falling devices usually nail the edges of the protection net or anti-falling plate to the well wall inside the wellhead through bolts. After long-term use, the bolts will become less firm due to aging and may become loose. Therefore, maintenance personnel need to go down into the well regularly to reset the protection net or anti-falling plate. However, when the maintenance personnel replace the protection net, they need to pull out the screws and then re-drill holes. This is not only inconvenient to operate, but also has a greater construction risk, and will also cause certain damage to the well body, reducing the service life of the well body.

[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a manhole anti-fall device for urban safety engineering, including a well body 1 and a manhole cover 2 located at the top of the well body 1. An anti-fall member 4 is installed on the step surface of the well body 1. The anti-fall member 4 includes a support ring 41 and an anti-fall plate 42, and the support ring 41 and the anti-fall plate 42 are movably connected through a plurality of clamping members 6;

[0033] The clamping member 6 is movably installed on the support ring 41. The clamping member 6 includes a fixed block 61, a plug pin rod 62 and a fixed rod 63. One end of the plug pin rod 62 and one end of the fixed rod 63 are both fixedly connected to the bottom surface of the fixed block 61, and the other end of the plug pin rod 62 and the other end of the fixed rod 63 both extend downward and are slidably fitted on the support ring 41.

[0034] In this solution, a plurality of first insertion holes 46 and second insertion holes 47 are formed on the support ring 41. The plug pin rod 62 and the fixed rod 63 are respectively slidably fitted in the first insertion hole 46 and the second insertion hole 47; a plurality of clamping blocks 45 are arranged on the side of the manhole cover 2. One end of the clamping block 45 is connected to the manhole cover 2, and the other end extends outward. A clamping hole 48 corresponding to the second insertion hole 47 is formed on the clamping block 45.

[0035] During use, the support ring 41 is fixedly installed on the tabletop of the well body 1, and the clamping member 6 is movably installed on the support ring 41 through the fixing rod 63. When installing the anti-falling plate 42, the top surface of the card hole 48 on the card block 45 on the side of the anti-falling plate 42 is aligned with the bottom surface of the second jack 47 on the support ring 41. Press the fixing block 61, and the pin rod 62 and the fixing rod 63 slide downward along the first jack 46 and the second jack 47 respectively after being pressed, until the bottom end of the pin rod 62 passes through the first jack 46 and is inserted into the card hole 48 on the card block 45, fixing the anti-falling plate 42 on the support ring 41. When it is necessary to disassemble and replace the anti-falling plate 42, pull the fixing block 61 upward. The upward movement of the fixing block 61 drives the pin rod 62 and the fixing rod 63 to move upward until the pin rod 62 is completely removed from the card hole 48.

[0036] Among them, by pulling the fixing block 61 upward, the fixing block 61 drives the fixing rod 63 and the pin rod 62 to slide upward along the second jack 47 and the first jack 46 respectively. The bottom end of the pin rod 62 is withdrawn from the card hole 48 and located in the first jack 46 to complete the disassembly of the anti-falling plate 42 from the support ring 41. The operation is convenient and fast, achieving the purpose of reducing the construction risk, reducing the damage to the well body 1, and improving the service life of the well body 1.

[0037] In this embodiment: A plurality of movable cavities 3 are formed on the step surface of the well body 1. One end of the fixing rod 63 away from the fixing block 61 penetrates through the support ring 41 and is located in the movable cavity 3. A limiting block 64 is connected to one end of the fixing rod 63 located in the movable cavity 3. A second spring 66 is sleeved on the lower end of the fixing rod 63. Two ends of the second spring 66 are respectively connected to the top surface of the limiting block 64 and the bottom surface of the support ring 41.

[0038] When it is necessary to install the anti-falling plate 42, just hold the fixing block 61 and drive the fixing block 61 to move upward. The upward movement of the fixing block 61 drives the fixing block 61 and the pin rod 62 to slide upward along the second jack 47 and the first jack 46 respectively. During the upward sliding process of the fixing rod 63, the second spring 66 will contract under the tension until the card hole 48 of the card block 45 on the side of the anti-falling plate 42 is aligned with the first jack 46. Then release the fixing block 61. The second spring 66 will be in a freely extended state without being subjected to tension and drive the fixing block 61 and the pin rod 62 to slide downward along the second jack 47 and the first jack 46 respectively until the pin rod 62 slides downward along the first jack 46 and is inserted into the card hole 48 to fix the anti-falling plate 42;

[0039] When it is necessary to disassemble the anti-falling plate 42, hold the fixing block 61 again and drive the fixing block 61 to move upward. The upward movement of the fixing block 61 drives the fixing block 61 and the pin rod 62 to slide upward along the second jack 47 and the first jack 46 respectively until the bottom end of the pin rod 62 completely breaks away from the card hole 48 and enters the first jack 46, achieving the purpose of quickly installing, fixing or disassembling the anti-falling plate 42.

[0040] In this embodiment: A clamping groove 43 is formed inside the support ring 41, and a plurality of mounting openings 44 communicating with the clamping groove 43 are formed on the top surface of the support ring 41. A plurality of blocking blocks 51 are installed in the clamping groove 43, and a support member 5 for supporting the insertion pin 62 is connected to one side of the blocking block 51.

[0041] The size of the clamping block 45 on the anti-falling plate 42 is adapted to the mounting opening 44. When the anti-falling plate 42 needs to be disassembled, only need to hold the fixing block 61 and drive the fixing block 61 to move upward, so that the insertion pin 62 is pulled out of the card hole 48 after being subjected to a pulling force. Then the worker moves the anti-falling plate 42 along the clamping groove 43 in a circular motion until the clamping block 45 moves to below the mounting opening 44 along the clamping groove 43, and the anti-falling plate 42 is removed from the support ring 41 along the mounting opening 44. In addition, during the process of the insertion pin 62 being taken out of the card hole 48 and the anti-falling plate 42 moving in a circular motion along the clamping groove 43, the support member 5 will pop out the connecting block 52, so that the bottom end of the insertion pin 62 contacts the top surface of the connecting block 52, supporting the insertion pin 62 and raising the height of the fixing block 61. When the worker forgets to install the anti-falling plate 42 and directly places the well cover 2 on the well body 1 to close it, the fixing block 61 will lift the well cover 2, making the well cover 2 unable to be properly adapted to the well opening of the well body 1, achieving the purpose of reminding the worker to install the anti-falling plate 42 and reducing potential safety hazards.

[0042] In this embodiment: The support member 5 includes a first spring 54 and a connecting block 52. A connecting hole 53 is formed on one side of the blocking block 51, and one end of the connecting block 52 is slidably fitted in the connecting hole 53. The two ends of the first spring 54 are respectively connected to one side of the inner wall of the connecting hole 53 and one side of the connecting block 52.

[0043] During the installation of the anti-falling plate 42, align the plurality of clamping blocks 45 on the side of the anti-falling plate 42 with the plurality of mounting openings 44 on the support ring 41 respectively until the clamping blocks 45 enter the clamping groove 43 through the mounting openings 44. Then rotate the anti-falling plate 42 through the handle on the anti-falling plate 42, so that the anti-falling plate 42 moves in a circular motion along the clamping groove 43 until the clamping block 45 contacts the connecting block 52, and continue to rotate the anti-falling plate 42. The anti-falling plate 42 drives the clamping block 45 to press the connecting block 52. After the connecting block 52 is pressed, the first spring 54 contracts until the connecting block 52 retracts into the connecting hole 53, and the clamping block 45 replaces the position of the connecting block 52 until the card hole 48 on the clamping block 45 is aligned with the first insertion hole 46 on the support ring 41. The second spring 66 changes from the contracted state to the free extended state and drives the fixed rod 63 to descend along the second insertion hole 47. The fixed rod 63 descending along the second insertion hole 47 drives the fixing block 61 and the insertion pin 62 to descend, and the insertion pin 62 descends along the first insertion hole 46 into the card hole 48 to realize the fixation of the anti-falling plate 42.

[0044] In this embodiment: It further includes a warning component 7, and the warning component 7 is movably installed on the anti-falling plate 42.

[0045] When the manhole cover 2 is lost or separated from the well body 1, the warning component 7 can remind passing pedestrians or vehicles, reducing the probability of pedestrians or vehicles falling into the well body 1.

[0046] In this embodiment: The warning component 7 includes a floating plate 71, a mounting rod 72 and a baffle 73. The bottom end of the mounting rod 72 is fixedly connected to the floating plate 71, and the top end of the mounting rod 72 is fixedly connected to the baffle 73. A through hole 8 is formed in the anti-falling plate 42, and the through hole 8 longitudinally penetrates the anti-falling plate 42. The upper end of the mounting rod 72 is slidably fitted in the through hole 8.

[0047] When there is heavy rain or a rainstorm, there is too much water on the road surface, and the water will enter the interior of the well body 1 along the water passing holes of the manhole cover 2. After the water level in the well body 1 gradually rises, once the water level in the well body 1 is higher than the manhole cover 2, the water will surge back and wash the manhole cover 2 out of the position of the well body 1. The anti-falling plate 42 is fixed on the step surface of the well body 1 through the clamping member 6. In this state, the floating plate 71 moves upward under the action of buoyancy until the top surface of the floating plate 71 contacts the bottom surface of the anti-falling plate 42. At the same time, during the upward movement of the floating plate 71, it will drive the mounting rod 72 and the baffle 73 at the top to rise along the through hole 8 on the anti-falling plate 42, so that the upper middle part of the mounting rod 72 and the height of the top plate are higher than the water accumulation depth, giving a visual reminder to pedestrians or passing vehicles.

[0048] In this embodiment: Reflective strips are bonded to both the top surface of the baffle 73 and the surface layer of the mounting rod 72.

[0049] When the manhole cover is lost or separated from the well body 1, the reflective strip can reflect light, giving a visual reminder to pedestrians or passing vehicles.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
