[0034] Figure 1 A fire hose cleaning device is shown, including a cleaning cylinder (first cleaning cylinder 1 and second cleaning cylinder 2) with a jacketed water chamber. Several cleaning water spray holes are provided on the inner wall of the cleaning cylinder. The water inlet of the cleaning cylinder is connected to the main water pipe 3. The water inlet of the main water pipe 3 can be connected to a water source. A main water pipe valve 4 is provided on the main water pipe 3. The main water pipe valve 4 is a one-way valve.
[0035] One end of the cleaning cylinder has an annular cleaning brush 11 on its inner wall; the lower part has a roller 13, which is freely rolled and sleeved on a roller column, and the roller column is fixedly connected to the inner wall of the cleaning cylinder. The lower end of the cleaning cylinder is provided with a drain valve 12, which can drain the water in the water chamber of the cleaning cylinder jacket after the cleaning work is completed.
[0036] A branch inlet pipe 5 is also provided on the side of the main water pipe 3. The inlet of the branch inlet pipe 5 is located at the front end of the main water pipe valve 4, and the outlet is located at the rear end of the main water pipe valve 4. The front end referred to in this article refers to the end of the water flow channel near the external water source, and the rear end refers to the end of the water flow channel near the cleaning cylinder. During operation, the water flows from the front end to the rear end.
[0037] A cleaning fluid storage tank 6 is also provided, which is connected to the water inlet branch pipe 4 through a cleaning fluid valve 7, which is a one-way valve.
[0038] The water inlet branch pipe 5 consists of a front water inlet branch pipe 501, a Venturi liquid mixer 502 and a rear water inlet branch pipe 503 connected in series in sequence. The front end of the front water inlet branch pipe 501 is the water inlet of the water inlet branch pipe 5.
[0039] like Figure 2 As shown, the Venturi inlet mixer 502 includes a mixer inlet pipe 5021, a mixer liquid inlet pipe 5022, a negative pressure chamber 5024, and a mixing outlet pipe 5023. The front end of the mixer inlet pipe 5021 is connected to the inlet branch pipe 501, and the rear section of the mixer inlet pipe 5021 has a constricted nozzle structure. The outer end of the mixer liquid inlet pipe 5022 is connected to the cleaning liquid storage tank 6 through a cleaning liquid valve 7. The front section of the mixing outlet pipe 5023 has a structure that expands towards the rear. The negative pressure chamber 5024 in the middle of the Venturi inlet mixer 502 is connected to the mixer inlet pipe 5021, the mixer liquid inlet pipe 5022, and the mixing outlet pipe 5023 respectively. The rear end of the mixing outlet pipe 5023 is connected to the rear inlet branch pipe 503. When water enters the mixer inlet pipe 5021, it is sprayed out from the constricted nozzle at the rear end, forming a negative pressure in the negative pressure chamber 5024. This draws the cleaning fluid in the cleaning fluid storage tank 6 into the mixer inlet pipe 5022, mixes with clean water, and then flows from the flared structure of the mixing outlet pipe 5023 to the rear inlet branch pipe 503.
[0040] At the end of the main water pipe 3, a three-way valve 10 and two inlet manifolds (first inlet manifold 8 and second inlet manifold 9) are also provided. The inlet of the three-way valve 10 is connected to the main water pipe 3, the first inlet manifold 8 is connected to the first cleaning cylinder 1, and the first inlet manifold 9 is connected to the second cleaning cylinder 2.
