Description

Technical Field

[0001] The utility model relates to the technical field of valve wells, in particular to a valve well cover. Background Art

[0002] Almost all buried pipelines have valve wells or inspection wells, including those in the gas industry. In urban pipe networks, many valves are installed for downstream control, and these valves are placed in valve wells. The valve well is generally composed of a well body, a well cover support, and a well cover.

[0003] A Chinese utility model patent with publication number CN211773929U discloses a valve well cover, including a well cover body, the edge of which is folded down to form a circular edge, and at least one vent hole is provided on the edge to connect the valve well with the atmosphere; the vent hole is arranged obliquely, and one end of the vent hole located on the inner side of the edge is higher than the other end located on the outer side of the edge. By changing the opening orientation of the vent hole, the vent hole is opened on the edge, and the vent hole is arranged obliquely, rainwater will not flow into the valve well through the vent hole during moderate or light rain, effectively solving the problem of rapid corrosion of the valve due to rainwater immersion.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device only blocks rainwater through the inclined air holes. When the valve well encounters heavy rain, water is easily accumulated on the road surface. At this time, the accumulated water is easy to pass through the air holes and enter the valve well, which can easily cause the valve to be corroded. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a valve well cover.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a valve well cover, comprising a well cover body and an annular rim arranged on the side wall of the well cover body, the bottom surface of the well cover body is provided with an installation groove, the inner wall of the installation groove is provided with a connecting groove, the inner bottom wall of the connecting groove is provided with a receiving groove, and the two opposite inner walls of the receiving groove are provided with sliding grooves, the well cover body is provided with a blocking mechanism for blocking rainwater, the blocking mechanism includes a detection component arranged on the well cover body for detecting rainwater and a closing component arranged on the well cover body for closing the connecting groove.

[0007] By adopting the above technical solution, when the valve well encounters rainy weather, rainwater accumulates on the road surface, so that rainwater enters the connecting groove, and at this time, part of the rainwater enters the receiving groove. In this process, the detection component detects rainwater in real time. When the detection component detects rainwater, the closing component automatically starts under the action of the detection component and closes the connecting groove, thereby reducing the probability of rainwater entering the valve well, thereby reducing the probability of the valve being corroded.

[0008] Furthermore, the detection component includes a slider slidably arranged in a slide groove, a slide plate installed together on the side walls of the two sliders close to each other, and a support spring with one end fixed to the bottom surface of the slide plate, and the other end of the support spring is fixed to the inner bottom wall of the accommodating groove.

[0009] By adopting the above technical solution, when rainwater enters the receiving groove, the rainwater accumulates on the upper surface of the slide plate, so that the slide plate moves downward under the action of the rainwater, thereby gradually compressing the support spring. At this time, the detection component can determine whether rainwater has entered the receiving groove by determining the position of the slide plate.

[0010] Furthermore, a limiting groove and a limiting hole are respectively provided on the inner top wall and the inner bottom wall of the connecting groove, a T-shaped groove is provided on the inner bottom wall of the accommodating groove, and the closing assembly includes a limiting plate slidably arranged in the limiting groove, a limiting spring at one end fixed on the side wall of the limiting plate away from the limiting hole, a first sliding rod fixed on the bottom surface of the sliding plate, a second sliding rod slidably arranged in the horizontal part of the T-shaped groove, and a connecting rope at one end fixed on the bottom surface of the limiting plate, the other end of the limiting spring is fixed on the inner wall of the limiting groove away from the limiting hole, the lower end of the first sliding rod is slidably connected to the vertical part of the T-shaped groove, the other end of the connecting rope extends into the horizontal part of the T-shaped groove and is fixed to the upper surface of the second sliding rod, and an inclined surface is provided on the edge where the upper surface of the second sliding rod intersects with the side wall away from the connecting rope.

[0011] By adopting the above technical solution, when the slide plate moves downward under the action of rainwater, the first slide bar moves downward with the slide plate, so that the first slide bar is pressed against the inclined surface, so that the second slide bar moves in a direction away from the vertical part of the T-shaped groove under the action of the first slide bar, so that the connecting rope moves with the second slide bar, and the limiting plate moves downward under the action of the connecting rope. Subsequently, the limiting plate and the limiting hole are connected to each other, so that the limiting plate closes the connecting groove, thereby reducing the probability of rainwater entering the valve well.

[0012] Furthermore, a first magnet block is disposed on the bottom surface of the limiting plate, and a second magnet block adsorbed to the first magnet block is disposed on the inner bottom wall of the limiting hole.

[0013] By adopting the above technical solution, when the limiting plate gradually approaches the limiting hole, the first magnet block and the second magnet block are attracted to each other, thereby accelerating the speed of the limiting plate closing the connecting groove, thereby further improving the sealing effect of the sealing component.

[0014] Furthermore, a rubber sheet for closing the accommodating groove is fixed on the inner wall of the accommodating groove, and the bottom surface of the rubber sheet is fixed to the upper surface of the slide plate.

[0015] By adopting the above technical solution, the rubber has good elasticity, and the rubber sheet made of rubber has good elasticity, thereby reducing the probability of rainwater directly contacting the skateboard, thereby reducing the probability of the support spring being corroded.

[0016] Furthermore, a drainage hole for slowly draining water is formed through the inner wall of the containing tank.

[0017] By adopting the above technical solution, when the rain stops near the valve well, the water accumulated on the road surface is gradually discharged through the sewer. At this time, the water in the connecting groove gradually flows out of the connecting groove, and then the water in the receiving groove is gradually discharged through the drainage hole, thereby reducing the probability of long-term accumulation of water in the receiving groove, which is conducive to extending the service life of the device.

[0018] Furthermore, an arc-shaped groove is provided on the upper surface of the manhole cover body, and an arc-shaped handle is rotatably provided in the arc-shaped groove.

[0019] By adopting the above technical solution, by designing the manhole cover body and the arc-shaped handle into one body, the staff can inspect the valve well anytime and anywhere without carrying tools, thereby reducing the operating difficulty of the staff.

[0020] Furthermore, a placement groove for accommodating fingers is provided on the side wall of the arc-shaped handle.

[0021] By adopting the above technical solution, the difficulty for the staff to separate the arc-shaped handle and the arc-shaped groove is reduced, thereby improving the use experience of the staff.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, when the valve well encounters rainy weather, rainwater accumulates on the road surface, so that the rainwater enters the connecting groove. At this time, part of the rainwater enters the receiving groove. In this process, the detection component detects the rainwater in real time. When the detection component detects the rainwater, the sealing component automatically starts under the action of the detection component and seals the connecting groove, thereby reducing the probability of rainwater entering the valve well, thereby reducing the probability of the valve being corroded;

[0024] 2. In the present application, when rainwater enters the receiving groove, the rainwater accumulates on the upper surface of the slide plate, so that the slide plate moves downward under the action of the rainwater, and then the support spring is gradually compressed. At this time, the detection component can determine whether the rainwater has entered the receiving groove by determining the position of the slide plate;

[0025] 3. In the present application, when the slide plate moves downward under the action of rainwater, the first slide bar moves downward with the slide plate, and then the first slide bar is pressed against the inclined surface, so that the second slide bar moves in a direction away from the vertical part of the T-shaped groove under the action of the first slide bar, so that the connecting rope moves with the second slide bar, and then the limit plate moves downward under the action of the connecting rope. Subsequently, the limit plate and the limit hole are connected to each other, so that the limit plate closes the connecting groove, thereby reducing the probability of rainwater entering the valve well.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0033] like Figure 1-5 As shown, the embodiment of the present application discloses a valve well cover, including a well cover body 1, an annular surrounding edge 11, a blocking mechanism 3, a first magnet block 6, a second magnet block 61 and a rubber sheet 7.

The blocking mechanism 3 is arranged on the manhole cover body 1 for blocking rainwater, and the blocking mechanism 3 includes a detection component 4 and a closing component 5. The detection component 4 is arranged on the manhole cover body 1 for detecting rainwater, and the detection component 4 includes a slider 41, a slide plate 42 and a support spring 43. The slider 41 is a rectangular block structure, and the slider 41 is slidably arranged in the slide groove 23. The slide plate 42 is a rectangular plate structure, and the slide plates 42 are installed together on the side walls of the two sliders 41 close to each other. One end of the support spring 43 is fixed to the bottom surface of the slide plate 42, and the other end of the support spring 43 is fixed to the inner bottom wall of the receiving groove 22.

[0035] When rainwater enters the receiving groove 22, the rainwater accumulates on the upper surface of the slide plate 42, so that the slide plate 42 moves downward under the action of the rainwater, thereby gradually compressing the support spring 43. At this time, the detection component 4 can determine whether rainwater has entered the receiving groove 22 by determining the position of the slide plate 42.

[0036] The inner top wall and the inner bottom wall of the connecting groove 21 are respectively provided with a limiting groove 44 and a limiting hole 45, and the inner bottom wall of the receiving groove 22 is provided with a T-shaped groove 46. The closing component 5 is arranged on the manhole cover body 1, and is used to close the connecting groove 21. The closing component 5 includes a limiting plate 51, a limiting spring 52, a first slide bar 53, a second slide bar 54 and a connecting rope 55. The limiting plate 51 is a rectangular plate-shaped structure, and the limiting plate 51 is slidably arranged in the limiting groove 44. One end of the limiting spring 52 is fixed on the side wall of the limiting plate 51 away from the limiting hole 45, and the other end of the limiting spring 52 is fixed on the inner wall of the limiting groove 44 away from the limiting hole 45. The first slide bar 53 is a rectangular rod-shaped structure, and the first slide bar 53 is fixed on the bottom surface of the slide plate 42, and the lower end of the first slide bar 53 is slidably connected with the vertical part of the T-shaped groove 46.

[0037] When the slide plate 42 moves downward under the action of rainwater, the first slide bar 53 moves downward with the slide plate 42, so that the first slide bar 53 is pressed against the inclined surface, so that the second slide bar 54 moves in a direction away from the vertical portion of the T-shaped groove 46 under the action of the first slide bar 53, so that the connecting rope 55 moves with the second slide bar 54, and the limiting plate 51 moves downward under the action of the connecting rope 55. Subsequently, the limiting plate 51 and the limiting hole 45 are connected to each other, so that the limiting plate 51 closes the connecting groove 21, thereby reducing the probability of rainwater entering the valve well.

[0038] The first magnet block 6 is a rectangular block structure, and the first magnet block 6 is arranged on the bottom surface of the limiting plate 51. The second magnet block 61 is a rectangular block structure, and the second magnet block 61 is arranged on the inner bottom wall of the limiting hole 45, and the second magnet block 61 and the first magnet block 6 are mutually adsorbed. When the limiting plate 51 gradually approaches the limiting hole 45, the first magnet block 6 and the second magnet block 61 are mutually adsorbed, thereby accelerating the speed at which the limiting plate 51 closes the connecting groove 21, thereby further improving the sealing effect of the sealing component 5.

Rubber has good elasticity, and the rubber sheet 7 made of rubber has good elasticity, thereby reducing the probability of rainwater directly contacting the slide plate 42, thereby reducing the probability of the support spring 43 being corroded.

[0040] In order to extend the service life of the device, a drainage hole 71 for slowly draining water is formed on the inner wall of the receiving groove 22. When the rain stops near the valve well, the water accumulated on the road surface is gradually discharged through the sewer. At this time, the water in the connecting groove 21 gradually flows out of the connecting groove 21, and then the water in the receiving groove 22 is gradually discharged through the drainage hole 71, thereby reducing the probability of long-term accumulation of water in the receiving groove 22, which is conducive to extending the service life of the device.

[0041] In order to improve the user experience of the staff, an arc groove 8 is provided on the upper surface of the manhole cover body 1, an arc handle 81 is rotatably provided in the arc groove 8, and a placement groove 9 for accommodating fingers is provided on the side wall of the arc handle 81.
