Description

Technical Field

[0001] This utility model relates to an anti-splash device, and more particularly to a protective device for unblocking pipes in sewage wells, belonging to the field of pipe unblocking technology. Background Technology

[0002] In urban drainage systems, clearing blockages in sewage wells is crucial for ensuring smooth drainage. With rapid urbanization, sewage well blockages are becoming increasingly frequent, highlighting the importance of unblocking these pipes. Currently, the common method is to use high-pressure water jets, which use high-pressure water to impact and disperse blockages in the pipes. However, when using high-pressure water jets to clear sewage wells, the high pressure can cause violent splashing of sewage under pressure, resulting in large amounts of sewage or solid waste being sprayed outside the well, causing inconvenience and safety hazards for on-site workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a protective device for unblocking pipes in sewage wells, which effectively prevents sewage from splashing to the outside of the well opening during the unblocking process, and protects the safety of workers and the hygiene of the surrounding environment.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A protective device for unblocking pipes in sewage wells includes a base plate, a surrounding plate, and an outer protective cover. A circular through hole is excavated in the center of the base plate, and an annular guide plate is provided below the circular through hole. The inner wall of the annular guide plate is connected to a tightening bolt by a thread. A surrounding plate is provided above the base plate, and an outer protective cover is provided outside the surrounding plate. A transparent cover plate is provided on the top of the outer protective cover, and a buffer net is provided inside the outer protective cover.

[0006] A notch is provided on one side of the enclosure, and a guide roller is provided at the notch. Limiting baffles are provided at both ends of the enclosure, and the bottom of the limiting baffles is fixedly connected to the base plate.

[0007] The outer cover has a cylindrical structure, and an extension plate is provided at the bottom of the outer cover. The extension plate is fixedly connected to the base plate by bolts. A rectangular through hole is provided at the bottom of the outer cover at the position corresponding to the limiting baffle.

[0008] The transparent cover plates are distributed in a hat shape and are fixedly connected to the top of the outer protective cover by bolts.

[0009] The outer diameter of the annular guide plate is smaller than the inner diameter of the sewage well, and the outer diameter of the base plate is larger than the inner diameter of the sewage well.

[0010] The positive and beneficial effects of this utility model are:

[0011] 1. This utility model uses a top-tightening bolt on the inner wall of the annular guide plate to fix the base plate; and uses a guide roller at the notch to facilitate the insertion and removal of the high-pressure water gun's guide wire or unblocking tool, making disassembly and assembly convenient and operation simple.

[0012] 2. This utility model effectively blocks the splashing of sewage during high-pressure water jet dredging by setting an outer protective cover on the outside of the enclosure and a transparent cover on the top of the outer protective cover, preventing sewage from splashing outside the well opening and protecting the surrounding environment and the safety of the staff; at the same time, the transparent cover not only ensures the sealing of the protective device, but also makes it easy for the staff to observe the situation inside the sewage well during operation and adjust the dredging operation in a timely manner.

[0013] 3. By setting a buffer net inside the protective cover, this utility model can further reduce the impact force of sewage, reduce the splash range of sewage, enhance the protective effect, and ensure the safety of construction. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further explained and described below with reference to the accompanying drawings:

[0020] See the example. Figures 1-4A protective device for unblocking pipes in sewage wells includes a base plate 1, a surrounding plate 5, and an outer protective cover 8. A circular through hole 2 is excavated in the center of the base plate 1. An annular guide plate 3 is provided below the circular through hole 2. A tightening bolt 4 is threadedly connected to the inner wall of the annular guide plate 3. The surrounding plate 5 is provided above the base plate 1 and is located on the base plate outside the circular through hole. The outer protective cover 8 is provided outside the surrounding plate 5. A transparent cover plate 11 is provided on the top of the outer protective cover 8. A buffer net 10 is provided inside the outer protective cover 8 and is located at the top of the outer protective cover.

[0021] A notch is provided on one side of the enclosure 5, and a guide roller 7 is provided at the notch. Limiting baffles 6 are provided at both ends of the enclosure 5. The bottom of the enclosure and the limiting baffles are fixedly connected to the base plate.

[0022] The outer cover 8 has a cylindrical structure. An integral extension plate 9 is provided on the outside of the bottom surface of the outer cover 8. Bolt holes are provided on the extension plate 9, and matching screws are provided at the positions of the bolt holes and the bottom plate. In use, the bolt holes on the extension plate are fitted over the outside of the screws, and the extension plate and the bottom plate are fixed together by matching nuts. A rectangular through hole 801 is provided on the bottom side of the outer cover 8 at the position of the limiting baffle 6. When the outer cover is placed on the bottom plate, the rectangular through hole is locked above the limiting baffle.

[0023] The transparent cover plate 11 is distributed in a hat shape and is fixedly connected to the top of the outer protective cover 8 by bolts.

[0024] Extended plates are provided on the outside of the top surface of the outer cover and the outside of the bottom surface of the transparent cover, and the two extended plates are fixed together by bolts.

[0025] The outer diameter of the annular guide plate 3 is smaller than the inner diameter of the sewage well, and the outer diameter of the base plate 1 is larger than the inner diameter of the sewage well. When in use, the base plate is placed above the sewage well, so that the annular guide plate extends into the sewage well and is clamped and fixed by the tightening bolts on the inner wall of the annular guide plate.

[0026] Working principle:

[0027] Before unblocking, place the base plate above the sewage well and secure it to the well using the tightening bolts on the inner wall of the annular guide plate to prevent displacement. Then, insert the high-pressure water gun into the sewage well, install the outer protective cover on the base plate, and attach a transparent cover to the top of the outer protective cover. During unblocking, when using the high-pressure water gun to clear the pipe, the high-pressure water flow will impact the blockage inside the pipe, generating a large amount of splashing sewage. The outer protective cover, base plate, and transparent cover further form a closed protective space to prevent sewage from splashing to the outside. At the same time, the buffer net inside the outer protective cover can reduce the impact force of the sewage and reduce the splash range, further enhancing the protective effect. The transparent cover design allows workers to clearly observe the unblocking situation inside the sewage well during operation and adjust the spray direction and intensity of the high-pressure water gun in a timely manner to ensure the smooth progress of the unblocking work.

[0028] This utility model combines a base plate, an outer protective cover, a buffer net, and a transparent cover to form a closed protective space with a certain buffering function. It can effectively block the violent splashing of sewage when the high-pressure water gun is used to unclog the pipe, prevent sewage from splashing outside the well opening, thereby protecting the health and safety of on-site personnel, reducing pollution to the surrounding environment, and improving the efficiency and safety of unclogging work.
