Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a gas release inspection well. Background Art

[0002] The inspection well used in municipal drainage is a facility used to inspect, clean and maintain pipes in urban drainage systems. Inspection wells are usually located at corners, slope changes or pipe intersections on the pipeline route, so as to check the status of the pipeline, clear blockages or perform repairs when necessary. Inspection wells are usually connected to upstream pipelines, and the high-speed and high-pressure water flow ejected from the upstream pipeline carries a large amount of gas. After the water flow hits the wall of the inspection well, the gas released from the water flow will increase the air pressure in the inspection well, causing the manhole cover of the inspection well to be lifted up by a large lifting force and deformed and damaged; on the other hand, under the impact of water flow and repeated flushing of rising gas, the wall of the inspection well is prone to fall off, which is not conducive to extending the service life of the inspection well. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a gas release inspection well, which is conducive to extending the service life of the inspection well.

[0004] The gas release inspection well according to the embodiment of the utility model comprises:

[0005] Well;

[0006] A water inlet pipe, the water inlet pipe is arranged on the well wall of the well, and the water inlet pipe is used to communicate with the upstream pipeline so that the water flow in the upstream pipeline can enter the well through the water inlet pipe;

[0007] A drain pipe, the drain pipe is arranged on the wall of the well, and the drain pipe is used to drain the water in the well out of the well;

[0008] A box body, the box body is arranged in the well, and a water inlet and a drain outlet are respectively opened on two opposite box walls of the box body, the water inlet is arranged corresponding to the water inlet pipe, so that the water flow sprayed from the water inlet pipe can pass through the water inlet and enter the box body, and the drain outlet is arranged corresponding to the drain pipe, so that the water in the box body can pass through the drain outlet and flow into the drain pipe;

[0009] A plurality of driven rotating components, each of which is disposed in the box body, each of which is rotatably connected to a box wall of the box body, and each of which is capable of abutting against the water flow sprayed from the water inlet pipe to rotate the plurality of driven rotating components;

[0010] A ventilation manhole cover is arranged at the upper end of the well, and the inner cavity of the well is connected with the outside atmosphere through the ventilation manhole cover.

[0011] At least the following beneficial effects:

[0012] The water inlet pipe is connected to the upstream pipeline, and the water flow in the upstream pipeline passes through the water inlet on the box through the water inlet pipe and is sprayed into the box. Multiple driven rotating components are arranged in the box, and can be rotatably connected to the box wall of the box. Multiple driven rotating components can abut against the water flow sprayed from the water inlet pipe. Under the impact of the water flow, multiple driven rotating components start to rotate. The driven rotating components can convert the kinetic energy of the water flow impact into mechanical energy of rotation, weakening the impact of the water flow and reducing the impact destructive force of the water flow. The water flow sprayed from the water inlet pipe is directly sprayed into the box, and the impact of the water flow directly acts on the box wall of the box, avoiding the impact of the water flow directly acting on the wall of the well, thereby avoiding the well wall of the well from being detached, which is beneficial to improving the service life of the well. The rotation and stirring of the driven rotating assembly can accelerate the bursting of bubbles in the water flow, so that the gas in the water flow that impacts the box wall and multiple driven rotating assemblies can be quickly released. Since the inner cavity of the box is connected to the inner cavity of the well, and the inner cavity of the well is connected to the outside atmosphere through the ventilation manhole cover, the pressure of the inner cavity of the well can always be consistent with the pressure of the outside atmosphere, so that the ventilation manhole cover will not be lifted up by the lifting force and deformed and damaged. Finally, the water accumulated in the box will pass through the drain port on the box and flow into the drain pipe to complete the gas release and energy dissipation of the gas release inspection well. The multiple driven rotating assemblies in the gas release inspection well can accelerate the release of gas in the water flow, which not only avoids the impact of the water flow directly acting on the well wall of the well, but also avoids the ventilation manhole cover being lifted up by the lifting force and deformed and damaged due to the increase in air pressure, protecting the well wall and ventilation manhole cover of the gas release inspection well from damage, which is conducive to extending the service life of the gas release inspection well.

The two pedals are arranged above the multiple rotating shafts, and the gap between the two pedals can allow the paddle board to pass through.

[0035] refer to Figures 1 to 3 According to the gas release inspection well of the embodiment of the utility model,

[0036] Well 100;

[0037] A water inlet pipe 110, which is disposed on the wall of the well 100 and is used to communicate with an upstream pipeline so that water in the upstream pipeline can enter the well 100 through the water inlet pipe 110;

[0038] A drain pipe 120, which is disposed on the wall of the well 100, and is used to drain water in the well 100 out of the well 100;

[0039] The box body 200 is arranged in the well 100. A water inlet and a drain outlet are respectively provided on two opposite box walls of the box body 200. The water inlet is arranged correspondingly to the water inlet pipe 110 so that the water flow sprayed from the water inlet pipe 110 can pass through the water inlet and enter the box body 200. The drain outlet is arranged correspondingly to the drain pipe 120 so that the water in the box body 200 can pass through the drain outlet and flow into the drain pipe 120.

[0040] A plurality of driven rotating components 300, each of which is disposed in the box body 200, each of which is rotatably connected to the box wall of the box body 200, and each of which is capable of abutting against the water flow sprayed from the water inlet pipe 110, so as to rotate the plurality of driven rotating components 300;

[0041] The ventilation manhole cover 140 is disposed at the upper end of the well 100 , and the inner cavity of the well 100 is connected to the outside atmosphere through the ventilation manhole cover 140 .

[0042] It can be understood that the water inlet pipe 110 is connected to the upstream pipe, and the water flow in the upstream pipe passes through the water inlet on the box 200 through the water inlet pipe 110 and is sprayed into the box 200. Multiple driven rotating components 300 are all arranged in the box 200, and can be rotatably connected to the box wall of the box 200. Multiple driven rotating components 300 can abut against the water flow sprayed from the water inlet pipe 110. Under the impact of the water flow, the multiple driven rotating components 300 start to rotate. The driven rotating components 300 can convert the kinetic energy of the water flow impact into the mechanical energy of rotation, weakening the impact of the water flow and reducing the impact destructive force of the water flow. The water flow sprayed from the water inlet pipe 110 is directly sprayed into the box body 200, and the impact of the water flow directly acts on the box wall of the box body 200, thereby preventing the impact of the water flow from directly acting on the wall of the well 100, thereby preventing the well wall of the well 100 from being separated, which is beneficial to improving the service life of the well 100. The rotation and stirring of the driven rotating assembly 300 can accelerate the rupture of bubbles in the water flow, so that the gas in the water flow impacting the box wall of the box body 200 and the multiple driven rotating assemblies 300 can be quickly released. Since the inner cavity of the box body 200 is connected to the inner cavity of the well 100, and the inner cavity of the well 100 is connected to the outside atmosphere through the ventilation manhole cover 140, the pressure of the inner cavity of the well 100 can always be consistent with the pressure of the outside atmosphere, thereby preventing the ventilation manhole cover 140 from being lifted by the lifting force and deformed and damaged. Finally, the water accumulated in the box body 200 will pass through the drain port on the box body 200 and flow into the drain pipe 120 to complete the gas release and energy dissipation of the gas release inspection well. The multiple driven rotating components 300 in the gas release inspection well can accelerate the release of gas in the water flow, which not only avoids the impact of the water flow directly acting on the wall of the well 100, but also avoids the ventilation well cover 140 being lifted up by the lifting force due to the increase in air pressure and deformed and damaged, protecting the well wall and ventilation well cover 140 of the gas release inspection well from damage, thereby helping to extend the service life of the gas release inspection well.

[0043] On the other hand, the upstream water flow may contain a certain amount of oxygen, carbon dioxide or other toxic and harmful gases. In the case of long-term accumulation and stagnation, the gas in the water flow will corrode the metal parts and concrete structures inside the inspection well, and if the water flow carrying a large amount of gas enters the downstream, it will damage the downstream pipes, valves, pumps and other equipment. Under the rotation of multiple driven rotating components 300 in the gas release inspection well, the bubbles in the water flow can be quickly broken, so that the gas in the water flow can be quickly released; and after the water flow impacts the box wall of the box body 200, the reaction force of the box wall of the box body 200 can also cause the bubbles in the water flow to break, so that the gas in the water flow can be quickly released. The box body 200 and multiple driven rotating components 300 in the gas release inspection well can quickly release the gas in the water flow, avoiding the gas in the water flow from damaging the inspection well and downstream facilities.

[0044] In the present invention, water flows from the back to the front, and a water outlet and a water inlet are respectively provided on the front and rear walls of the box body 200 that are opposite to each other.

[0045] refer to Figure 1 and Figure 3 , the water inlet pipe 110 is arranged obliquely, and the water outlet end of the water inlet pipe 110 faces obliquely downward, and the bottom wall of the box body 200 includes a first bottom wall 210 and a second bottom wall 220, and the first bottom wall 210 and the second bottom wall 220 are both arranged obliquely, and the angle formed by the first bottom wall 210 and the second bottom wall 220 faces upward. It can be understood that the water outlet end of the water outlet pipe faces obliquely downward, so that the water flow can be sprayed obliquely downward. The bottom wall of the box body 200 is composed of two obliquely arranged first bottom walls 210 and second bottom walls 220, and the angle formed by the first bottom wall 210 and the second bottom wall 220 faces upward. Since the first bottom wall 210 and the second bottom wall 220 are both arranged obliquely, the water flow sprayed obliquely downward can impact on the first bottom wall 210 and the second bottom wall 220 more quickly, shortening the distance that the water flow impacts on the bottom wall of the box body 200, so that the gas in the water flow can be released early, which is conducive to improving the release effect of the gas in the water flow. On the other hand, the water flow sprayed obliquely downward can impact the first bottom wall 210 and the second bottom wall 220 more quickly, so that the impact force of the water flow can be weakened earlier, which is beneficial to improving the water flow energy dissipation effect of the box body 200.

[0046] Specifically, the included angles between the first bottom wall 210 and the second bottom wall 220 and the bottom wall of the well 100 are both 8°.

[0047] refer to Figure 1 and Figure 2 The driven rotating assembly 300 includes a rotating shaft 310 and a plurality of paddles 320. Both ends of the rotating shaft 310 are rotatably connected to two opposite walls of the box body 200. The plurality of paddles 320 are arrayed on the rotating shaft 310 along the axis of the rotating shaft 310. The plurality of paddles 320 can abut against the water flow sprayed from the water inlet pipe 110 to rotate the rotating shaft 310 and the plurality of paddles 320. It can be understood that the water flow sprayed from the water inlet pipe 110 will impact the plurality of paddles 320 on the rotating shaft 310. Since both ends of the rotating shaft 310 are rotatably connected to two opposite walls of the box body 200, under the impact of the water flow, the plurality of paddles 320 rotate and drive the rotating shaft 310 to rotate, so that the kinetic energy of the water flow impact is converted into the mechanical energy of the rotating shaft 310 and the plurality of paddles 320 to complete the energy dissipation effect on the water flow. On the other hand, the rotation of the paddles 320 can stir the water flow, causing the bubbles in the water flow to burst quickly, thereby accelerating the release of gas in the water flow. Specifically, the rotating shaft 310 is parallel to the left and right directions. Further, the rotating multiple paddles 320 can accelerate the flow of gas in the well 100, achieving rapid ventilation between the gas in the well 100 and the outside atmosphere.

[0048] refer to Figure 1 and Figure 2 The gas release inspection well also includes two pedals 230, both of which are arranged in the box body 200, and both of which are connected to the two opposite box walls of the box body 200. The two pedals 230 are arranged above the multiple rotating shafts 310, and the gap between the two pedals 230 can be used for the paddle board 320 to pass through. It can be understood that the multiple driven rotating components 300 each include a rotating shaft 310 and multiple paddle boards 320, and the gap between the two paddle boards 320 can be used for the paddle board 320 to pass through. The two pedals 230 can provide a stepping platform for maintenance personnel who enter the well 100 for maintenance and overhaul operations, so that the maintenance personnel can stand on the two pedals 230 and perform maintenance and overhaul on the facilities in the well 100, thereby improving the convenience of the maintenance personnel in maintaining the gas release inspection well. Specifically, the two pedals 230 are respectively connected to the left and right box walls opposite to the box body 200. The two pedals 230 extend in the front-to-back direction.

[0049] As an embodiment of the present invention, two pedals 230 can be connected to two opposite walls of the box body 200 in a sliding manner in the up-down direction. It can be understood that the space between the two pedals 230 and the bottom wall of the box body 200 is used to accommodate the water flow sprayed from the water inlet pipe 110. By moving the two pedals 230 up and down, the distance between the two pedals 230 and the bottom wall of the box body 200 can be changed, and then the space for storing water in the box body 200 can be changed to adapt to the flow of different upstream pipes, so as to avoid the water in the box body 200 from being unable to be discharged in time, so that the water flow sprayed from the water inlet pipe 110 can smoothly enter the box body 200 and be smoothly discharged from the drain pipe 120.

[0050] As an embodiment of the utility model, the gas release inspection well further includes two fastening assemblies, and the two fastening assemblies are respectively used to fix the two pedals 230 on the two opposite walls of the box body 200. It can be understood that after the distance between the two pedals 230 and the bottom wall of the box body 200 is adjusted, the maintenance personnel can use the two fastening assemblies to fix the two pedals 230 on the two opposite walls of the box body 200, thereby preventing the two pedals 230 from shaking or moving, and improving the stability of the two pedals 230.

[0051] As an embodiment of the utility model, a plurality of threaded holes are provided on the box wall of the box body 200, and the plurality of threaded holes are distributed in the up-down direction. A connecting plate is provided on the pedal board 230, and a through hole is provided on the connecting plate. The fastening assembly includes a bolt, and the bolt is passed through the through hole and is threadedly connected with one of the threaded holes. The nut of the bolt can be pressed against the connecting plate, so that the pedal board 230 is fixed to the box wall of the box body 200 through the connecting plate. It can be understood that the distance between the pedal board 230 and the bottom wall of the box body 200 can be adjusted by threading the bolts with the inner walls of the threaded holes at different heights.

[0052] As an embodiment of the present invention, the box body 200 is made of stainless steel. It is understandable that the box body 200 made of stainless steel has good corrosion resistance and can extend the service life of the box body 200. On the other hand, the box body 200 made of stainless steel has high strength and hardness, can withstand water flow impact and external pressure, is not easy to deform or break, and ensures that the gas release inspection well can be in normal working condition for a long time.

[0053] refer to Figure 2 , the diameter of the water inlet pipe 110 is smaller than the diameter of the drain pipe 120. It is understandable that the diameter of the water inlet pipe 110 is smaller than the diameter of the drain pipe 120, which can ensure that the water inlet pipe 110 can meet the flow requirements of the drain pipe 120, achieve flow matching, avoid the water flow being too large or too small to affect the drainage effect of the drain pipe 120, and avoid a large amount of water accumulating in the box 200.

[0054] refer to Figure 1 and Figure 2 The upper end of the well 100 is provided with an installation annular groove 130, and the ventilation manhole cover 140 is arranged in the installation annular groove 130. It should be explained that the ventilation manhole cover 140 is usually provided with air holes or air permeable grids, which can allow air to flow freely into the well 100 to ensure good ventilation inside the well 100.

[0055] refer to Figure 1 , the drain port is close to the bottom wall of the box body 200. It can be understood that the drain port is close to the bottom wall of the box body 200, so that the water in the box body 200 can flow into the drain pipe 120 faster to speed up the drainage efficiency of the box body 200.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
