Description

Technical Field

[0001] This utility model relates to cleaning tools, specifically to a manhole cleaning device. Background Technology

[0002] Long-term wind or rain erosion can bring fine sand and soil into the gap between the manhole and the manhole cover. Over time, the accumulation of dust, mud and other debris gradually fills the gap and hardens, causing the manhole cover to jam.

[0003] The usual method is for sanitation workers to forcibly pry it up with crowbars or other means, or to use a liquid system to lift it up. Referring to Chinese authorized patent CN112978648B, a municipal road manhole cover auxiliary prying device is disclosed.

[0004] In the prior art, including the aforementioned patent, due to the lack of effective tools, if sanitation workers regularly clean the dust, mud, and other debris filling the gap between the manhole cover and the sewer opening, the problem of the manhole cover getting stuck can be effectively avoided.

[0008] The irregularly shaped cutting blade includes a blade tip, the opening diameter of which increases from the blade tip toward the handle portion;

[0009] The irregular-shaped cutting tool includes a vertex ridge, on which a notch is provided.

[0010] Preferably, the tail of the handheld part is fixedly installed with a connecting air pipe, which is fixedly connected to the hose at the output end of the air compressor.

[0011] Preferably, an air blowing tube is fixedly provided at the end of the handheld part, and the air blowing tube is fitted inside the V-shaped structure of the irregular cutter.

[0012] Preferably, the irregularly shaped cutting tool is divided into a first arc-shaped part and a second arc-shaped part according to its structure, and the inner arc apex of the first arc-shaped part and the second arc-shaped part face opposite directions.

[0013] Preferably, the irregular-shaped cutting tool is divided into an extension portion according to its structure. The extension portion is connected to the end of the second arc-shaped portion, and the notch is located on the extension portion and distributed close to the second arc-shaped portion.

[0014] Preferably, the air blowing pipe is axially parallel to the extension.

[0015] Preferably, the irregularly shaped cutting tool is made of stainless steel.

[0016] In the above technical solution, the manhole cleaning device provided by this utility model has the following beneficial effects: the blade tip is embedded in the gap between the manhole and the manhole cover, and then as the opening gap of the inserted V-shaped structure decreases, the irregular cutting blade is embedded in the gap, and then it is moved to clean the dust and dirt in the entire gap.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, a manhole cleaning device includes an air compressor 1 and a handheld part 2, the end of which is provided with an irregularly shaped cutter 3 with a V-shaped cross-section.

[0025] The irregular cutting blade 3 includes a blade tip 31, the opening diameter of which increases from the blade tip 31 toward the handle 2;

[0026] The irregular cutting tool 3 includes a vertex ridge 32, on which a notch 321 is provided.

[0027] Specifically, a connecting air pipe 21 is fixedly installed at the tail of the handheld part 2, which is fixedly connected to the hose at the output end of the air compressor 1. Furthermore, the entire irregularly shaped cutter part 3 is made of flexible stainless steel. Figure 2 As shown, during the cleaning process, the irregularly shaped cutter 3 moves from left to right, thereby scraping the dust across the notch 321, while some of the dust moving forward will move up along the apex ridge 32 and overflow into the gap.

[0028] During the cleaning process, the air compressor 1 needs to be started to continuously supply air, so that the air is blown through the handheld part 2 to the irregular cutter 3, that is, to clean the inside of the V-shaped structure.

[0029] The blade tip 31 is embedded in the gap between the manhole and the manhole cover. As the opening gap of the inserted V-shaped structure decreases, the irregular cutting blade 3 is embedded in the gap and then moved to clean the dust and dirt in the entire gap.

[0030] As a further embodiment of this utility model, an air blowing pipe 4 is fixedly provided at the end of the handheld part 2, and the air blowing pipe 4 is attached to the inside of the V-shaped structure of the irregular cutter 3.

[0031] Furthermore, in combination Figure 2 and Figure 3 As shown, the irregularly shaped cutter 3 is divided into a first arc-shaped part 33 and a second arc-shaped part 34 according to its structure, and the inner arc apex of the first arc-shaped part 33 and the second arc-shaped part 34 face opposite directions. Therefore, during the cleaning of the gap, the dust at the front end will accumulate and move up along the outer arc surface of the second arc-shaped part 34 to overflow the gap or cross the notch 321, and then be blown out of the gap by the air pipe 4.

[0032] As a further embodiment of this utility model, the irregularly shaped cutter 3 is divided into an extension 35 according to its structure. The extension 35 is connected to the end of the second arc-shaped portion 34, and the notch 321 is located on the extension 35 and distributed close to the second arc-shaped portion 34. The air blowing pipe 4 is axially parallel to the extension 35.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
