Description

Technical Field

[0001] This utility model relates to the technical field of municipal drainage pipeline facilities, and in particular to a sewage inspection well with internal and external ventilation functions. Background Technology

[0002] In recent years, several accidents involving explosions of sewage inspection wells caused by the burning of firecrackers have occurred in my country. The reason is that domestic sewage has a high organic content, which decomposes to produce flammable and explosive biogas. Conventional sewage inspection wells have poor ventilation, preventing the timely release of biogas. Once a spark occurs, a deflagration accident can easily occur. Since sewage pipes transport sewage daily, using electric power to drive the ventilation of inspection wells would not only waste energy but also increase the workload of subsequent equipment maintenance and the possibility of electrical leakage triggering accidents. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sewage inspection well with internal and external ventilation functions, which can achieve automatic ventilation inside and outside the well by utilizing the power of hydraulic transmission, thereby reducing safety risks.

[0004] A sewage inspection well with internal and external ventilation function according to an embodiment of the present invention includes a well body, a hydraulic conversion device, and an exhaust manhole cover. An inlet pipe and an outlet pipe are respectively provided on both sides of the well body, and the inlet pipe and the outlet pipe are arranged opposite to each other. The hydraulic conversion device includes a hydraulic conversion mechanism and an exhaust blade. The hydraulic conversion mechanism is disposed in the well body, and the exhaust blade is connected to the hydraulic conversion mechanism. The hydraulic conversion mechanism converts the kinetic energy of the water flowing through the well body into mechanical energy to drive the exhaust blade to rotate. The exhaust blade is used to push the air inside the well body. The exhaust manhole cover is disposed on the well body, located directly above the exhaust blade. The exhaust manhole cover has several automatically opening and closing exhaust vents, and the air pushed by the exhaust blade is discharged from the exhaust vents.

[0005] It has at least the following beneficial effects: sewage enters the well body through the inlet pipe and is discharged through the outlet pipe. The hydraulic conversion mechanism can utilize the kinetic energy of the sewage to convert it into rotational mechanical energy, thereby driving the exhaust paddle to rotate. This will cause the air in the well body to be discharged through the exhaust port, avoiding the accumulation of flammable and explosive exhaust gases in the well and thus avoiding safety risks.

Detailed Implementation

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figures 1 to 5 This utility model discloses a sewage inspection well with internal and external ventilation function, including a well body 10, a hydraulic conversion device 20, and an exhaust cover 30. An inlet pipe 11 and an outlet pipe 12 are respectively arranged on both sides of the well body 10, with the inlet pipe 11 and outlet pipe 12 arranged opposite to each other. The hydraulic conversion device 20 includes a hydraulic conversion mechanism 21 and an exhaust blade 22. The hydraulic conversion mechanism 21 is installed in the well body 10, and the exhaust blade 22 is connected to the hydraulic conversion mechanism 21. The hydraulic conversion mechanism 21 converts the kinetic energy of the water flowing through the well body 10 into mechanical energy to drive the exhaust blade 22 to rotate. The exhaust blade 22 is used to push the air inside the well body 10. The exhaust cover 30 is installed on the well body 10, located directly above the exhaust blade 22. The exhaust cover 30 has several automatically opening and closing exhaust vents 31, from which the air pushed by the exhaust blade 22 is discharged.

[0020] It is understandable that sewage enters the well body 10 through the inlet pipe 11 and is discharged through the outlet pipe 12. The hydraulic conversion mechanism 21 can utilize the kinetic energy of the sewage to convert it into rotational mechanical energy, thereby driving the exhaust paddle 22 to rotate. This will cause the air inside the well body 10 to be discharged through the exhaust port 31, thus avoiding the accumulation of flammable and explosive exhaust gases inside the well and thus avoiding safety risks.

[0021] Reference Figure 1 and Figure 2The hydraulic conversion mechanism 21 includes a central shaft 211, a first impeller 212, and several bearings 213. The central shaft 211 is rotatably mounted in the well body 10. The inner ring of the bearing 213 is fitted onto the central shaft 211. The first impeller 212 is mounted on the outer ring of the bearing 213. The exhaust blade 22 is rotatably mounted on the central shaft 211 through the bearing 213. The exhaust blade 22 is connected to the first impeller 212, and the first impeller 212 and the exhaust blade 22 rotate synchronously.

[0022] Understandably, when sewage enters the well body 10 through the inlet pipe 11, the water flow impacts the first impeller 212, causing it to rotate around the central axis 211. This rotation drives the exhaust blade 22 to rotate around the central axis 211. At this time, the air inside the well body 10 rises under the push of the exhaust blade 22 and is discharged from the exhaust port 31. The hydraulic conversion mechanism 21 achieves power-free operation, significantly reducing facility energy consumption and avoiding electrical risks.

[0023] Reference Figures 2 to 6 It also includes an exhaust vent opening device 40, which is installed on the exhaust well cover 30 and connected to the hydraulic conversion device 20. The exhaust vent opening device 40 is used to open or close the exhaust vent 31 to complete the automatic exhaust or closure of the well body 10.

[0024] It should be noted that the exhaust vent opening device 40 can open the exhaust vent 31 when ventilation is needed, and close the exhaust vent 31 when ventilation is not needed, thereby reducing the probability of rainwater or debris falling onto the ground.

[0025] Reference Figures 2 to 6 The exhaust vent opening device 40 includes a second paddle plate 41, an exhaust vent cover 42, a cover guide assembly 43, and a transmission assembly 44. The second paddle plate 41 is fixedly connected to the central shaft 211. The second paddle plate 41 rotates under the impact of water flow, driving the central shaft 211 to rotate. The exhaust vent cover 42 is rotatably set below the exhaust well cover 30 through the cover guide assembly 43. The exhaust vent cover 42 is connected to the central shaft 211 through the transmission assembly 44. The central shaft 211 drives the exhaust vent cover 42 to rotate through the transmission assembly 44. The initial position of the exhaust vent cover 42 is located directly below several exhaust vents 31. After the exhaust vent cover 42 rotates, the exhaust vents 31 are opened.

[0026] It should be noted that in the embodiments of this utility model, the water flow drives the second paddle plate 41 to rotate, which in turn drives the central shaft 211 to rotate. The torque of the central shaft 211 is transmitted to the exhaust port cover plate 42 under the transmission component 44, so that the exhaust port cover plate 42 moves to open the exhaust port 31 and complete the ventilation.

[0027] Reference Figure 2 and Figure 6The exhaust port cover 42 includes a base plate 421, a plurality of cover plate connecting rods 422 and a plurality of cover plates 423. The plurality of cover plate connecting rods 422 are evenly arranged around the base plate 421, and the plurality of cover plates 423 are disposed at the ends of the cover plate connecting rods 422. The number of cover plates 423 is the same as the number of exhaust ports 31.

[0028] Reference Figure 2 and Figure 6 The transmission assembly 44 includes a cross-shaped slot 441 and a cross-shaped retainer 442. The cross-shaped slot 441 is formed on the base plate 421, and the cross-shaped retainer 442 is disposed on the central shaft 211 and is housed in the cross-shaped slot 441.

[0029] It is understandable that the torque is transmitted by inserting the cross-shaped retainer 442 at the top of the central shaft 211 into the cross-shaped retainer 441 on the base plate 421, so that the rotation of the second paddle plate 41 can be smoothly transmitted to the exhaust port cover plate 42.

[0030] Reference Figure 6 The cover guide assembly 43 includes a slide groove 431, a guide post 432, and a snap-fit ​​plate 433. The slide groove 431 is formed on the base plate 421 and is an arc groove. The slide groove 431 is concentric with the base plate 421 and the central angle of the slide groove 431 is less than 45 degrees. The guide post 432 is disposed on the exhaust manhole cover 30 and is inserted into the slide groove 431. The snap-fit ​​plate 433 is rotatably disposed at the end of the guide post 432. The base plate 421 is located between the snap-fit ​​plate 433 and the exhaust manhole cover 30.

[0031] Understandably, when the substrate 421 rotates to a certain angle and the cover plate 423 no longer overlaps with the exhaust port 31, the guide post 432 will hit the side wall of the slide groove 431. At this time, the rotation of the substrate 421 is restricted to prevent the substrate 421 from rotating continuously under the drive of the water flow, which would cause the exhaust port 31 to open and close frequently and affect the ventilation efficiency.

[0032] Reference Figure 6 The cover plate guide assembly 43 also includes a reset fixing post 434 and a reset spring 435. There are several reset fixing posts 434, which are arranged on the exhaust manhole cover 30 and are evenly distributed along the circumference of the exhaust manhole cover 30. There are several reset springs 435, one end of which is connected to the reset fixing post 434 and the other end is connected to the cover plate connecting rod 422. The reset spring 435 is configured to pull the cover plate connecting rod 422 so that the cover plate 423 returns to below the exhaust port 31.

[0033] It should be noted that in the embodiments of this utility model, when no water flows into the well body 10 and no external force is applied to the second slurry plate 41, the reset spring 435 can pull the cover plate connecting rod 422, so that the cover plate 423 resets and covers the exhaust port 31, thus completing the closure of the exhaust port 31.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
