Description

Technical Field

[0001] The utility model relates to the field of municipal facility construction projects, in particular to a sewage well on a municipal road. Background Art

[0002] Sewage wells are an important part of the urban drainage system, mainly used to collect and discharge urban domestic sewage and rainwater. They are usually located below the ground and connected to the drainage pipes of homes, buildings and streets. The collected sewage will eventually be directed to sewage treatment plants or natural water bodies. During the sewage discharge process, noise may be generated inside the sewage well, destroying the sound environment around the sewage well and affecting the quality of life of nearby residents. Therefore, the sewage well needs to be silenced.

[0003] In response to the above problems, a sewage well for municipal roads is now developed. Utility Model Content

[0004] In order to overcome the disadvantage that noise may be generated inside the sewage well during the sewage discharge process, destroying the sound environment around the sewage well and affecting the quality of life of nearby residents, the utility model provides a sewage well on a municipal road.

[0005] The technical solution of the present utility model is: a sewage well for a municipal road, comprising a well body, a first support plate connected to the upper portion of the well body, a well cover clamped on the first support plate, two drainage openings on the well cover, a second support plate connected to the middle portion of the well body, an anti-fall net clamped on the second support plate, a double-cavity silencer structure connected to the middle and lower portion of the well body, a sound-absorbing middle cavity connected to the inside of the double-cavity silencer structure, and reinforcing ribs of a reinforcing structure connected between the double-cavity silencer structure and the well body.

[0006] Further description: the well body is provided with a limiting groove for limiting the well cover.

[0007] It is further explained that the manhole cover is a detachable connection structure.

[0008] It is further explained that the second support plate is connected with a triangular rib plate for reinforcement.

[0009] It is further explained that the anti-fall net is a flexible steel cable structure.

[0010] It is further explained that the dual-cavity silencer structure is funnel-shaped.

[0011] By adopting the above technical solution, compared with the existing technology, the utility model has the following advantages:

[0012] The utility model is provided with a double-cavity silencer structure. When the sound wave enters the small-diameter part of the double-cavity silencer structure, it will be reflected. Part of the sound wave will be reflected back, and the rest of the sound wave will continue to move. The two parts of the sound waves meet again to form destructive interference, thereby reducing noise. In the narrower part in the middle, the energy density of the sound wave is higher. At this time, the sound-absorbing material inside the double-cavity silencer structure will absorb part of the sound wave energy, thereby reducing the intensity of the sound wave. When the sound wave enters a larger space again, the energy density is reduced and the sound wave further diffuses, thereby reducing the noise caused by the flow of sewage, improving the sound environment around the sewage well, and improving the quality of life of nearby residents.

[0017] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," and "downwardly" are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Numerical designations such as "first" and "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0018] A sewage well on a municipal road, such as Figure 1-Figure 3 As shown, it includes a well body 1, a first support plate 4 is connected to the upper part of the well body 1, a manhole cover 2 is clamped on the first support plate 4, a limiting groove for limiting the manhole cover 2 is provided on the well body 1, the manhole cover 2 is a detachable connection structure, two drainage outlets 3 are opened on the manhole cover 2, a second support plate 6 is connected to the middle part of the well body 1, a triangular rib for reinforcement is connected to the second support plate 6, an anti-fall net 5 is clamped on the second support plate 6, the anti-fall net 5 is a flexible steel cable structure, a double-cavity silencer structure 7 is connected to the middle and lower part of the well body 1, the double-cavity silencer structure 7 is funnel-shaped, a sound-absorbing middle cavity 9 is connected to the inside of the double-cavity silencer structure 7, and reinforcing ribs 8 of the reinforcing structure are connected between the double-cavity silencer structure 7 and the well body 1.

[0019] It should be noted that the sewage well is an important part of the urban drainage system, which is mainly used to collect and discharge urban domestic sewage and rainwater. It is usually located below the ground and is connected to the drainage pipes of homes, buildings and streets. The collected sewage is eventually directed to sewage treatment plants or natural water bodies. During the sewage discharge process, noise may be generated inside the sewage well, affecting the normal life of nearby residents. The sewage well needs to be silenced. The sewage is discharged into the well body 1 through the drain outlet 3. The flexible steel cable structure of the anti-fall net 5 can intercept objects or people who accidentally fall, and at the same time absorb the impact on objects or people, and play a protective role for objects or people. In order to achieve the effect of silencing and noise reduction, a double-cavity silencer structure 7 is set in the middle and lower part of the well body 1. When the sewage well is in operation, the sound waves enter the double-cavity silencer. When the sound structure 7 has a small diameter, reflection will occur. Part of the sound waves will be reflected back, and the rest of the sound waves will continue to move. When the two parts of the sound waves meet again, destructive interference will be formed, thereby reducing noise. In the narrower part in the middle, the energy density of the sound waves is higher. At this time, the sound-absorbing material inside the dual-cavity sound-absorbing structure 7 will absorb part of the sound wave energy, thereby reducing the intensity of the sound wave. When the sound wave enters a larger space again, the energy density is reduced and the sound wave further diffuses. The dual-cavity sound-absorbing structure 7 can optimize the flow of sewage, reduce the formation of turbulence and eddy currents, thereby reducing the noise caused by the flow of sewage, improving the sound environment around the sewage well, and improving the quality of life of nearby residents. The reinforcing ribs 8 can strengthen the structure between the well body 1 and the dual-cavity sound-absorbing structure 7, making the dual-cavity sound-absorbing structure 7 more stable.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
