Description

Technical Field

[0001] The utility model belongs to the technical field of pipelines, and particularly relates to a sewage suction hose. Background Technique

[0002] Water tanks (or water towers) are generally installed at high places on the roof, and some are even installed on the slopes of the roof. Moreover, the water tanks are relatively tall and have a smooth surface. If cleaning personnel climb up to clean the water tanks, they are likely to slip. Therefore, cleaning the water tanks is an extremely dangerous task. Every year, many people are injured or even killed due to falling from a height during water tank cleaning. After the top cover of the water tank is opened, since the water tank is relatively deep and the hands cannot reach it, tools similar to mops need to be used, but there are many dead corners that cannot be cleaned; another problem is that the deeper the water tank, the longer the handle required and the greater the torque, making it very strenuous to clean.

[0003] Generally, water tanks are not deliberately cleaned. Most of the time, it is only when sewage appears in the faucet that people will observe the water tank and find that there is a large amount of dirt accumulated at the bottom of the water tank. If this happens during a water shortage, it is a very embarrassing choice. If the water tank is emptied completely for cleaning, it means there will be no water available, and it is very wasteful!

[0004] To solve the above problems, the applicant's prior invention patent application CN 110773528 A proposed a water tower automatic cleaner, and its main cleaning method is as follows: The cleaner is installed at the bottom of the water tower, and the cleaning pipe (i.e., the cleaning tube in the above patent) for cleaning is attached to the bottom surface of the water tower. The cleaning pipe is formed by combining a main pipe body and several bristles. Each bristle is provided with a dirt suction port, and the dirt suction port leads to the main pipe body. Moreover, the dirt suction ports on each bristle are of the same size, and the dirt suction capacity and the acting surface are the same, playing a role of uniform dirt suction. During operation, the cleaning pipe rotates along the bottom surface of the water tower. During the rotation process, the bristles scrape off the water scale at the bottom of the water tower and then suck it into the pipe body through the dirt suction ports on the bristles, and finally discharge it through the pipe body. Although this structure can better solve the problem of cleaning the water tank without stopping the water, new problems are found in the actual use process: In practice, the diameter of the dirt suction port of the bristle is fixed, and the actual dirt suction area is determined by the angle formed between the bristle and the bottom surface of the water tower during the working process. When the bottom surface is a flat surface, the actual acting areas of the dirt suction ports of each bristle are basically the same. Therefore, the dirt suction ports can suck dirt evenly during the movement of each bristle. However, for some water towers with uneven bottom surfaces or environments with stepped structures at the bottom, when the cleaning pipe is attached to the bottom surface, the bristles of the cleaning pipe at the steps will be lifted due to the stepped surface, and the angle between the bristle and the stepped surface will become smaller, or even float to a position where it cannot contact the stepped surface. At this time, the acting area of the dirt suction port of the bristle here will increase, and the water flow rate here will increase when sucking water, resulting in the concentration of the nearby water flow to be discharged here, and the water flow rate of the bristles near the steps will decrease, ultimately leading to uneven scale treatment and affecting the cleaning effect. Summary of the Invention

[0005] The purpose of the present utility model is to provide a dirt suction hose with a simple structure, which can adaptively deform according to the shape of different water tower bottoms and improve the cleaning degree of adsorbing impurities at the bottom of the water tower to solve the above problems.

A dirt suction channel communicating the dirt suction port with the inside of the pipe body is provided inside the dirt suction nozzle, and an opening is provided near the dirt suction port of the dirt suction nozzle.

[0008] Preferably, in the dirt suction hose provided by the present utility model, it may further have the following characteristics: The opening is a linear opening, and the dirt suction nozzle is divided into an upper half piece and a lower half piece with the linear opening as the boundary, and the length of the lower half piece is shorter than that of the upper half piece.

[0026] Embodiment:

[0027] This embodiment provides a sewage suction hose 40. As Figures 1 - 3 shown, the sewage suction hose 40 includes a tube body 41 and a plurality of sewage suction nozzles 42. The plurality of sewage suction nozzles 42 are closely arranged on one side of the tube body 41 along the length direction of the tube body. Among them, one end of the sewage suction nozzle 42 is combined with the tube body 41, and the other end has a sewage suction port 43. A sewage suction channel 44 communicating the sewage suction port 43 with the inside of the tube body 41 is provided inside the sewage suction nozzle 42. An opening is provided near the sewage suction port 43 of the sewage suction nozzle 42. This opening is preferably a linear opening 45, thereby dividing the sewage suction nozzle 42 into an upper half 451 and a lower half 452. The length of the lower half 452 is shorter than the length of the upper half 451. As Figure 1As shown in the figure, when the sewage suction hose 40 is installed at the bottom of the water tower, the lower half 452 of the sewage suction hose 40 is located at the bottom, and the upper half 451 covers above the lower half 452. Setting the length of the lower half 452 to be shorter than that of the upper half 451 can ensure that the scale scraped off can all be brought into the sewage suction channel 44 by the water flow along the sewage suction port 43, and then discharged along the pipe body 41. The linear opening 45 provided near the sewage suction port 43 of the sewage suction nozzle 42 can cause the sewage suction nozzle 42 to deform when encountering scenarios such as an uneven sewage suction surface or a stepped structure, making it fit more closely to the bottom surface, so as to reduce the gap between the sewage suction nozzles, thereby improving the cleanliness of adsorbing impurities at the bottom of the water tower and having a wider scope of application.

[0028] As Figures 4 - 6 shown, taking a water tower with a step at the bottom as an example, there is a stepped structure 51 in the middle of the bottom surface of the water tower, which divides the bottom surface of the water tower into a first surface 52 and a second surface 53 with different heights. The sewage suction hose 40 is installed at a position close to the bottom surface. Due to the setting of the stepped structure 51, the position of the sewage suction nozzle 42 will be slightly misaligned. In this embodiment, taking the height of the first surface 51 being lower than that of the second surface 53 as an example, when the sewage suction nozzle 42 located on the second surface 53 rotates, the upper half 451 and the lower half 452 of the sewage suction port 43 can be deformed (as Figure 6 shown, Figure 6 for Figure 4 the side view of the sewage suction nozzle 42 located on the second surface 53 at point B in

[0029] order to adjust the sewage suction port 43 to adapt to the bottom surface of the water tower.

[0030] In this embodiment, the upper half 451 is flat, and the lower half 452 is arc-shaped with an opening facing the upper half 451. The lower half 452 can scrape off the scale during the rotation process, and then be driven by the lower half 452 and brought into the sewage suction channel 44 by the water flow along the sewage suction port 43.

[0031] The pipe body and the sewage suction nozzle are integrally formed by a flexible rubber material, which can be deformed and is convenient for adapting to water towers with different bottom surface structures.

[0032] A weight part is provided on the inner wall of the pipe body 41. This weight part can be a convex block formed on the inner wall of the pipe body 41 or a separately placed split weight block to increase the weight of the pipe body 41, so as to ensure that the pipe body 41 can adhere to the surface of the bottom of the water tower during operation.

[0033] In another embodiment, the pipe body 41 can be in the form of one end being open and the other end being closed. The open end is connected to a driving device (for driving the pipe body 41 to rotate and sucking in and discharging water flow). The water flow only enters through the sewage suction port 43 on the sewage suction nozzle 42, then enters the pipe body 41 along the sewage suction channel 44, and then flows out from the open end.

[0034] The above embodiments are only preferred embodiments of the present invention and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention. For example, in the above embodiments, the cleaning pipeline at the bottom of the water tower is taken as an example for description. In actual situations, it can also be used in other scenarios where cleaning and sewage discharge are required.
