Abstract
Description
Technical Field
[0001] This utility model relates to a foam liquid pipe cleaner and belongs to the field of pipe cleaning technology. Background Technology
[0002] Currently, a fire extinguisher window is installed every 50 meters inside highway tunnels. In long tunnels, a foam liquid tank needs to be installed in the fire extinguisher window. To solve the problem of long maintenance time and high debugging requirements for the water film forming fire extinguishing system in tunnels that fails to produce foam liquid, the working principle of foam water fire extinguishing was analyzed. It was found that the reason for the failure to produce foam was that impurities and other small foreign objects entered the foam liquid pipeline in the foam liquid tank. When passing through the one-way valve and the proportional mixing valve, they blocked the needle-sized channel. This caused the foam liquid in the foam liquid tank to be unable to be discharged from the pipeline, resulting in insufficient mixing with the water source in the water pipe.
[0003] When foam liquid is transported through pipelines in foam liquid tanks, it is easily blocked by foreign objects due to the narrow passages of check valves and mixing valves. This will cause the foam liquid to drain slowly from the foam tank, and in severe cases, the foam liquid cannot flow. Usually, it is necessary to unscrew the nuts between the pipes and valves and then fill the tank with high-pressure gas to blow out the internal impurities. However, frequently opening the nuts at the valves can easily cause the connection to loosen, and long-term use may lead to leakage problems. Utility Model Content
[0004] This invention provides a foam liquid pipe cleaner to solve the technical problem that foam liquid tank pipes are easily blocked and cannot discharge liquid.
[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

After prolonged use, the first pipe connects to a gas cylinder, using high-pressure gas to blow air into the one-way valve and mixing valve. Airflow is released by moving the blockage block. High-pressure gas can quickly clear the one-way valve and mixing valve during unblocking, resolving blockages caused by prolonged use. The second pipe removes blown-out impurities, preventing them from clogging subsequent pipe valves. The cleaner allows for rapid operation, improving pipe unblocking efficiency.

[0027] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0028] like Figure 1-5 As shown, the foam liquid drain cleaner includes:
[0029] Foam liquid tank 1, the bottom of which is fixedly connected to water pipe 5 via drain pipe 4, the ends of which are fixedly connected to one-way valve 6 and mixing valve 7 respectively, and the two ends of which are fixedly connected to air outlet mechanism and air inlet mechanism respectively. The air outlet mechanism is composed of a first pipe body 8, and a plug 11 is movably sleeved inside the first pipe body 8. The air inlet mechanism is composed of a second pipe body 16, and a plug 19 is movably sleeved inside the second pipe body 16. The first pipe body 8 and the second pipe body 16 are located at the two ends of one-way valve 6 and mixing valve 7 respectively.
[0030] In this technical solution, both ends of the foam liquid tank 1 are fixedly connected to the side plate 2. The foam liquid tank 1 is fixedly installed inside the fire box through the side plate 2, and a liquid level pipe 3 is fixedly connected to one side of the foam liquid tank 1. The foam liquid tank 1 is fixed inside the fire box by screws on the side plate 2. When the water pipe 5 is transporting water, the foam liquid is transported into the water pipe 5 through the drain pipe 4 to mix and form foam liquid. The liquid level can be easily observed through the liquid level pipe 3, and timely replenishment is convenient.
[0031] In this technical solution, a block 11 is slidably connected inside the first pipe body 8. The two ends of the block 11 have an arc-shaped cross-section. The bottom of the block 11 has an inclined notch 12. The notch 12 is located on the side of the block 11 near the mixing valve 7. The block 11 can move stably vertically inside the first pipe body 8. The position of the block 11 can control the passage of the drain pipe 4. When the block 11 is moved to the inside of the first pipe body 8 below the drain pipe 4, the drain pipe 4 normally transports foam liquid. When clearing the block, the block 11 is moved above the drain pipe 4. At this time, the block 11 blocks the drain pipe 4 on its left side. At this time, the gas in the drain pipe 4 on the right side of the block 11 enters the first pipe body 8 through the notch 12 and is discharged through the cap 9.
[0032] In this technical solution, a fixed shaft 13 is fixedly connected to the top of the block 11. The fixed shaft 13 has a U-shaped hollow cross-section. A rotating shaft 14 is rotatably connected inside the fixed shaft 13. The rotating shaft 14 is fixedly connected to the bottom of the handle 15. Through the cooperation of the fixed shaft 13 and the rotating shaft 14, the handle 15 can drive the rotating shaft 14 to rotate inside the fixed shaft 13.
[0033] In this technical solution, a screw cap 9 is threaded onto the bottom of the first pipe body 8. A sealing ring 10 is fixedly connected inside the screw cap 9, and the sealing ring 10 is in close contact with the bottom edge of the first pipe body 8. Before unblocking the drain pipe 4, the screw cap 9 is unscrewed so that the gas inside can be discharged from the bottom of the first pipe body 8. After unblocking, when the block 11 is moved above the screw cap 9, the screw cap 9 is tightened so that the sealing ring 10 seals its bottom.
[0034] In this technical solution, the middle part of the first tube body 8 is connected to the drain pipe 4, and the top of the first tube body 8 is threadedly connected to the handle 15. The handle 15 extends into the fixed shaft 13. By rotating the handle 15, the block 11 can be driven to move vertically inside the first tube body 8 to achieve the position adjustment function.
[0035] In this technical solution, a connecting pipe 17 is fixedly connected to the top of the second pipe body 16. The top of the second pipe body 16 is connected to the plug 19 via a spring 18. The connecting pipe 17 is fixedly connected to the gas cylinder 26 via an air pipe 25. During unblocking, the gas cylinder 26 is connected to the connecting pipe 17 via the air pipe 25. When the valve on the gas cylinder 26 is opened, high-pressure gas enters the interior of the second pipe body 16 through the air pipe 25 and the connecting pipe 17. The positive pressure formed pushes the plug 19 downward, causing... When the plug 19 blocks the drain pipe 4 on its right side, the slot 21 is connected to the drain pipe 4 on the left side of the plug 19. At this time, the high-pressure gas is discharged from the bottom of the second pipe body 16 after passing through the one-way valve 6 and the mixing valve 7. After the blockage is completed, the gas cylinder 26 is disconnected, and the elasticity of the spring 18 pulls the plug 19 back to its original position. At this time, the plug 19 abuts against the limit ring 23, and the through hole 20 corresponds exactly to the drain pipe 4, so that the foam liquid can be transported from the through hole 20 at the plug 19 without affecting the transport of the foam liquid.
[0036] In this technical solution, two symmetrically distributed ribs 24 are fixedly connected to the inner wall of the second tube body 16. Grooves 22 are provided on both sides of the plug 19, and the ribs 24 are fitted into the grooves 22. The stable movement of the plug 19 can be achieved through the cooperation of the ribs 24 and the grooves 22.
[0037] In this technical solution, the middle part of the second tube body 16 is connected to the drain pipe 4, and a limiting ring 23 is fixedly connected inside the second tube body 16. The limiting ring 23 is correspondingly arranged above the plug 19. The limiting ring 23 is used to restrict the position of the plug 19, so that the through hole 20 corresponds to the drain pipe 4.
[0038] In this technical solution, the bottom of the plug 19 is provided with through holes 20 corresponding to the drain pipe 4, and the top of the plug 19 is provided with a groove 21. The groove 21 is located on the side of the plug 19 near the one-way valve 6. By setting the groove 21, when the plug 19 moves down, the groove 21 and the drain pipe 4 are interconnected, which facilitates the discharge of high-pressure gas in the gas cylinder 26.
[0039] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
