Description

Technical Field

[0001] This application relates to the technical field of municipal engineering, and in particular to a structure for a municipal safety drainage well. Background Technology

[0002] In the construction of municipal roads, drainage wells connected to the municipal drainage system are usually installed on both sides of the road. The drainage wells are mainly used to quickly collect the water accumulated on the municipal road into the municipal drainage system, so as to avoid water accumulation on the municipal road for a long time. The drainage wells are generally set in the low-lying parts of the municipal road. When it rains, the rainwater will naturally flow along the slope of the municipal road, so as to be collected through the drainage wells set in the low-lying parts.

[0003] In related technologies, drainage wells mainly consist of a well body and a well cover. The lower end of the well body is connected to the municipal drainage system, and the upper end of the well body is connected to the road surface of the municipal road. The well cover is detachably installed inside the upper end of the well body, and the well cover is provided with at least two through holes, through which rainwater can enter the well body. A protective structure such as a hanging net is also installed inside the upper end of the well body, so that if a pedestrian accidentally steps into the well body, the hanging net can prevent the pedestrian from falling directly to the bottom of the well, effectively ensuring the safety of pedestrians.

[0004] The main reason pedestrians step into manholes is that the manhole covers have been moved. With the improvement of social awareness, the theft of manhole covers has been greatly reduced. Currently, the main reason for the removal of manhole covers is that when there is severe water accumulation during rainy days, the openings on the manhole covers are no longer sufficient to meet the drainage needs. At this time, municipal workers can only open the entire manhole cover to expand the drainage area. This situation mainly occurs during heavy rain. Because during heavy rain, municipal workers cannot guard the drainage well for a long time after opening the manhole cover. Therefore, they can usually only set up guardrails around the drainage well. However, the guardrails can also be washed away by heavy rain, leaving the open drainage well unprotected, thus leading to the aforementioned risks.

[0005] Regarding the aforementioned technologies, the applicant believes that even if a hanging net is installed inside the drainage well, if a pedestrian is crossing by bicycle or motorcycle, and the bicycle or motorcycle misses its mark, it is easy to hit the upper edge of the well body, which would still not cause significant injury to the pedestrian. Therefore, further improvements are needed. Summary of the Invention

[0006] The purpose of this application is to provide a municipal safety drainage well structure that reduces the risk of pedestrians tripping into the well.

[0007] The present application provides a municipal safety drainage well structure, which adopts the following technical solution.

[0008] A municipal safety drainage well structure includes a well body and a cover body. The cover body includes a connecting cover and a lifting cover. The connecting cover is arranged in a circular shape and is detachably installed inside the upper end of the well body. The connecting cover is provided with a plurality of drainage through holes. The lifting cover is installed in the middle of the connecting cover in a lifting manner.

[0009] The lifting cover has two states. When the lifting cover is in the first state, it is located inside the connecting cover, and the upper surface of the lifting cover is basically horizontal with the upper surface of the connecting cover. When the lifting cover is in the second state, it is located above the middle of the connecting cover, and a drainage channel is formed between the bottom surface of the lifting cover and the inner hole of the connecting cover.

[0010] Specifically, the cover is used to protect the well body. By dividing the cover into a connecting cover and a lifting platform, when the drainage holes on the cover cannot meet the normal drainage needs, municipal personnel can lift the lifting cover to form a drainage channel between the lifting cover and the connecting cover, thereby expanding the water flow area of ​​the drainage well and effectively speeding up the drainage efficiency of the drainage well. Furthermore, because the lifting cover is still suspended directly above the middle of the connecting cover when it is lifted, it can fundamentally prevent pedestrians from stepping into the hole.

[0011] Furthermore, the bottom periphery of the lifting cover is provided with several raised sections, each of which is equidistantly arranged around the axis of the lifting cover, and each of the raised sections is provided with an arched part made of elastic material at the end away from the lifting cover. When the lifting cover is in the second state, each of the arched parts is pressed against the upper surface of the connecting cover.

[0012] Specifically, by utilizing the cooperation between the raised part and the arched part, when the lifting cover is pulled up, the arched part can press against the upper surface of the connecting cover, so that the lifting cover can remain in the second state for a long time. Furthermore, by utilizing the cooperation between the arched part and the inner wall of the connecting cover, the lifting cover is not easily separated from the connecting cover when it is not subjected to a large external force, thus avoiding the step difference of the manhole cover during normal use.

[0013] Furthermore, a connecting ring is provided below the connecting cover and is coaxially arranged with the connecting cover; a connecting shaft is provided on the bottom surface of the lifting cover and inserted into the connecting ring; and a concave area is provided on the upper surface of the lifting cover, with a handle provided in the concave area.

[0014] Specifically, the handle makes it easy for municipal workers to pull up the lifting cover, and the recessed area can hide the handle to prevent it from sticking out of the upper surface of the lifting cover. The cooperation between the connecting ring and the connecting shaft can guide the lifting direction of the lifting cover.

[0015] Furthermore, the bottom surface of the connecting cover is provided with several connecting ribs, each of which is equidistantly arranged around the axis of the connecting cover, and the length direction of each connecting rib extends along the radial direction of the connecting cover. Both ends of each connecting rib are respectively connected to the bottom surface of the connecting cover and the outer wall of the connecting ring to form a whole.

[0016] Specifically, the connecting ribs can connect the connecting cover and the connecting ring into one unit, and when the lifting cover is in the first state, they can also support the bottom surface of the lifting cover.

[0017] Furthermore, the upper surface of the lifting cover is provided with a light-emitting module, which has a positive electrode support and a negative electrode support. The lower ends of the positive electrode support and the negative electrode support extend out and are exposed to the outer wall of the connecting shaft. A positive electrode conductive ring and a negative electrode conductive ring are arranged vertically inside the connecting ring. A battery is also arranged inside the connecting ring, with its positive and negative electrodes connected to the positive electrode conductive ring and the negative electrode conductive ring, respectively. When the lifting cover is in the second state, the parts of the positive electrode support and the negative electrode support that are exposed to the connecting shaft are in contact with the positive electrode conductive ring and the negative electrode conductive ring, respectively.

[0018] Specifically, by utilizing the coordination between the light-emitting module, positive electrode support, negative electrode support, positive electrode conductive ring, negative electrode conductive ring and the battery, the light-emitting module can automatically light up when the lifting cover is in the second state, so as to serve as a warning.

[0019] Furthermore, the lifting cover and the connecting shaft are integrally molded by injection molding. The positive and negative electrode supports are made of copper pillars of different lengths. Both the positive and negative electrode supports are enclosed within the connecting shaft, and both the positive and negative electrode supports are exposed outside the connecting shaft by bending in a direction away from the axis of the connecting shaft. The connecting cover and the connecting ring are integrally molded by injection molding. Both the positive and negative conductive rings are coaxially arranged with the connecting ring and are enclosed within the connecting ring. The inner diameters of the positive and negative conductive rings are connected to the inner diameter of the connecting ring.

[0020] Specifically, injection molding can provide insulation protection for the positive and negative terminals, the positive conductive ring, and the negative conductive ring, ensuring their normal operation.

[0021] Furthermore, two sealing rings are provided on the inner wall of the connecting ring. The two sealing rings are respectively located near the upper and lower ends of the connecting ring, and both sealing rings are tightly connected to the outer wall of the connecting shaft. When the lifting cover is raised and lowered, the parts of the positive electrode support and the negative electrode support exposed outside the connecting shaft are located in the area between the two sealing rings.

[0022] Specifically, the use of sealing rings can further enhance the sealing fit between the connecting shaft and the connecting ring, preventing moisture from accidentally entering between the connecting shaft and the connecting ring and causing corrosion to the positive and negative terminals, positive and negative conductive rings, thus further ensuring the safe use of the positive and negative terminals, positive and negative conductive rings.

[0023] Furthermore, a limiting ring is provided at the lower end of the connecting shaft. The limiting ring is detachably connected to the connecting shaft by means of a threaded connection. The limiting ring is located below the connecting ring. When the lifting cover is in the second state, the limiting ring abuts against the bottom of the connecting ring.

[0024] Specifically, by utilizing the cooperation between the limiting ring and the connecting ring, the highest position of the lifting cover can be limited, preventing the lifting cover from being subjected to excessive impact and separating from the connecting cover when the water pressure inside the drainage well is too high, thus ensuring the safe use of the lifting cover.

[0025] Furthermore, a float is provided at the lower end of the connecting shaft. The float is hollow inside and is connected to the limiting ring as a whole and is located below the limiting ring.

[0026] Specifically, the use of floats can increase the buoyancy of the lift cover, making it easier for the cover to rise when the water pressure inside the drainage well is too high, so that the water in the drainage well can be discharged in an emergency, ensuring the safe use of the municipal drainage system.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It can fundamentally prevent pedestrians from falling into the well, effectively ensuring the safe use of drainage wells;

[0029] 2. It can serve as a luminous warning under specific working conditions, reminding pedestrians to detour and further ensuring safety;

[0030] 3. When the water pressure inside the drainage well is too high, the water flow area can be increased without the need for municipal personnel to operate, so that the water in the drainage well can be discharged in an emergency. Attached Figure Description
