Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to an energy dissipation 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. In order to prevent the upstream high-speed and high-pressure water flow from damaging pipes, valves, pumps and other equipment, energy dissipation devices are usually installed in the inspection well to weaken the impact of high-speed and high-pressure water flow. The upstream water flow often carries a large amount of impurities. As the inspection well is used for a longer time, the impurities will accumulate and rot in the inspection well and produce toxic and harmful gases. Toxic and harmful gases will accumulate in the inspection well and cannot dissipate quickly, which is not conducive to maintenance personnel entering the inspection well for inspection and maintenance.

[0035] refer to Figure 1 and Figure 2 According to the energy dissipation inspection well of the embodiment of the utility model,

[0036] Well 100;

[0037] A rotational energy dissipation device 200, which is rotatably disposed on the bottom wall of the shaft 100;

[0038] A water inlet pipe 110 is provided on the wall of the well 100. The water inlet pipe 110 is used to supply the upstream water flow into the well 100. The water outlet end of the water inlet pipe 110 faces the rotary energy dissipation device 200, so that the water flow ejected from the water inlet pipe 110 can impact the rotary energy dissipation device 200 and cause the rotary energy dissipation device 200 to rotate;

[0039] 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;

[0040] A ventilation manhole cover 400 is provided at the upper end of the shaft 100, and the inner cavity of the shaft 100 is connected to the outside atmosphere through the ventilation manhole cover 400;

[0041] The ventilation blades 300 are arranged in the shaft 100. The ventilation blades 300 are transmission-connected to the rotating energy dissipation device 200. The ventilation blades 300 can rotate along with the rotating energy dissipation device 200. The ventilation blades 300 are used to blow air from bottom to top so that the air in the shaft 100 can pass through the ventilation manhole cover 400 and be discharged into the outside atmosphere.

[0042] It is understandable that the water inlet pipe 110 is connected to the upstream pipeline. The water flow from the upstream is sprayed into the well 100 through the water inlet pipe 110. Since the water outlet end of the water inlet pipe 110 faces the rotary energy dissipation device 200, the water flow sprayed from the water inlet pipe 110 will impact the rotary energy dissipation device 200. Under the impact of the water flow, the rotary energy dissipation device 200 starts to rotate. The rotary energy dissipation device 200 can convert the kinetic energy of the water flow impact into mechanical energy of rotation, weakening the impact of the water flow and avoiding the impact of the water flow from damaging the well 100. Finally, the water in the well 100 is discharged from the well 100 through the drain pipe 120 to complete the energy dissipation effect on the water flow. The ventilation blades 300 are connected to the rotating energy dissipation device 200 by transmission. During the rotation of the rotating energy dissipation device 200, the rotating energy dissipation device 200 can drive the ventilation blades 300 to rotate together, so that the ventilation blades 300 can blow air from bottom to top, so that the air in the well 100 can pass through the ventilation manhole cover 400 and be discharged to the outside atmosphere, thereby allowing the toxic and harmful gases in the well 100 to dissipate quickly. The rotation of the ventilation blades 300 can keep the inner cavity of the well 100 at a negative pressure, realize the continuous ventilation between the air in the inner cavity of the well 100 and the outside atmosphere, avoid the volume of toxic and harmful gases in the well 100 and produce adverse effects on maintenance personnel, and facilitate maintenance personnel to enter the well 100 for inspection and maintenance.

[0043] refer to Figure 1 and Figure 2 The rotary energy dissipation device 200 includes a rotating rod 210 and a plurality of baffles 220. The rotating rod 210 is parallel to the up-down direction. The lower end of the rotating rod 210 is rotatably connected to the bottom wall of the well 100. The plurality of baffles 220 are arranged on the rotating rod 210 along the axis of the rotating rod 210. The plurality of baffles 220 are used to abut against the water flow sprayed from the water inlet pipe 110, so that the plurality of baffles 220 drive the rotating rod 210 to rotate. It can be understood that the water flow sprayed from the water inlet pipe 110 will impact the plurality of baffles 220 on the rotating rod 210. Since the lower end of the rotating rod 210 is rotatably connected to the bottom wall of the well 100, under the impact of the water flow, the plurality of baffles 220 rotate and drive the rotating rod 210, so that the kinetic energy of the water flow impact is converted into the mechanical energy of the rotating rod 210 and the plurality of baffles 220 to complete the energy dissipation effect on the water flow.

[0044] refer to Figure 1 and Figure 2The rotary energy dissipation device 200 also includes an energy dissipation slag collection bucket 230. A mounting hole is provided on the bottom wall of the energy dissipation slag collection bucket 230. The rotating rod 210 is inserted into the mounting hole and connected to the inner wall of the mounting hole. The energy dissipation slag collection bucket 230 is arranged below the plurality of baffles 220. The bottom wall of the energy dissipation slag collection bucket 230 is used to abut against the water flow splashed from the plurality of baffles 220, and the energy dissipation slag collection bucket 230 can collect impurities in the water flow. It can be understood that the water flow sprayed from the water inlet pipe 110 will splash on the baffle 220 after impacting the baffle 220, and the water flow splashed from the baffle 220 also has a certain impact force. Part of the water flow splashed from the baffle 220 can flow into the energy dissipation slag collection bucket 230 below the multiple baffles 220, and part of the water flow splashed from the baffle 220 can impact the inner wall of the energy dissipation slag collection bucket 230, weakening the impact force of the splashed water flow, preventing the splashed water flow from directly impacting the bottom wall of the shaft 100, and further preventing the bottom wall of the shaft 100 from being damaged by the impacted water flow. The energy dissipation slag collection bucket 230 is connected to the rotating rod 210. On the other hand, the energy dissipation slag collection bucket 230 can collect impurities (such as leaves, etc.) carried in the water flow, making it convenient for subsequent maintenance personnel to enter the shaft 100 to clean up the impurities.

[0045] As an embodiment of the utility model, the energy dissipation slag collection barrel 230 and the ventilation blade 300 are both made of stainless steel. It is understandable that the energy dissipation slag collection barrel 230 and the ventilation blade 300 are made of stainless steel, which can prevent the ventilation blade 300 and the energy dissipation barrel from rusting and being damaged. On the other hand, the ventilation blade 300 can also be made of plastic material.

[0046] refer to Figure 1 The ventilation blade 300 is connected to the upper end of the rotating rod 210. It can be understood that the ventilation blade 300 is connected to the upper end of the rotating rod 210, so that the rotating rod 210 can drive the ventilation blade 300 to rotate while rotating, and then the ventilation blade 300 can blow air from bottom to top to ensure that the inner cavity of the well 100 can always be in negative pressure.

[0047] refer to Figure 1 and Figure 3The energy dissipation inspection well also includes a support member 140, which is provided with a support hole 141. The support member 140 is disposed between the ventilation blades 300 and the plurality of baffles 220. The support member 140 is connected to the inner wall of the well 100, and the rotating rod 210 is passed through the support hole 141. It can be understood that under the impact of the water flow and the rotation of the ventilation blades 300, the rotating rod 210 will shake during the rotation process. The rotating rod 210 is passed through the support hole 141 on the support member 140, and the hole wall of the support hole 141 can abut against the rotating rod 210, so that the hole wall of the support hole 141 can support the rotating rod 210, thereby avoiding the shaking of the rotating rod 210 during the rotation process and improving the rotation stability of the rotating rod 210 and the plurality of baffles 220.

[0048] refer to Figure 2 , the water inlet pipe 110 is arranged on the side of the rotating rod 210. It can be understood that the water inlet pipe 110 is arranged on the side of the rotating rod 210, so that the water flow sprayed from the water inlet pipe 110 can directly act on the multiple baffles 220 on the rotating rod 210, avoiding the water sprayed from the water inlet pipe 110 directly impacting the rotating rod 210, thereby enabling the rotating rod 210 and the multiple baffles 220 to rotate quickly, which is conducive to improving the energy dissipation effect of the rotating rod 210 and the multiple baffles 220.

[0049] refer to Figure 1 , the water inlet pipe 110 is arranged above the drain pipe 120, and the drain pipe 120 is close to the bottom wall of the well 100. It can be understood that the water inlet pipe 110 is higher than the drain pipe 120 to prevent the water in the drain pipe 120 from flowing back into the water inlet pipe 110. On the other hand, the drain pipe 120 is close to the bottom wall of the well 100, which helps to quickly drain the water in the well 100, prevent blockage and affect the drainage efficiency of the drain pipe 120.

[0050] refer to Figure 1 and Figure 2 , the diameter of the drainage pipe 120 is larger than the diameter of the water inlet pipe 110. It is understandable that, since the water inlet pipe 110 is connected to an upstream pipeline for conveying high-speed and high-pressure water flow, the flow rate of water ejected from the water inlet pipe 110 is relatively large. In order to ensure that the drainage flow rate of the well 100 matches the water inlet flow rate, the diameter of the drainage pipe 120 is larger than the diameter of the water inlet pipe 110, which is conducive to quickly draining the water in the well 100 and avoiding a large amount of water from accumulating in the well 100.

[0051] refer to Figure 1 The upper end of the well 100 is provided with an installation annular groove 130, and the ventilation manhole cover 400 is arranged in the installation annular groove 130. It should be explained that the ventilation manhole cover 400 is usually provided with air holes or air-permeable grids, which allow air to flow freely into the well 100, ensuring that the well 100 is well ventilated.

[0052] 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.
