Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline leak point detection, and particularly relates to a rapid detection device for stainless steel pipeline leak points. Background Technique

[0002] The stainless steel water pipeline is carefully manufactured with high-quality stainless steel material, and has excellent corrosion resistance, high temperature resistance and anti-aging performance. Its inner wall is smooth, the water flow resistance is small, effectively ensuring the purity and pollution-free of water quality. It is widely used in fields such as household water supply, industrial circulating water system, drinking water project, etc. To avoid water leakage in the stainless steel pipeline, relevant personnel will conduct leakage detection on it. The existing detection methods are mostly to seal the inlet and outlet of the pipeline first, and then check whether the pipeline leaks by sending air, so as to know whether there is a leakage point in the pipeline.

[0003] Chinese Patent with publication number "CN214467925U" discloses a rapid detection device for water supply pipeline leak points, which relates to the technical field of water supply pipeline detection, including a main body. The inner wall of the main body is fixedly connected with the bottom of a linear motor. The transmission shaft of the linear motor penetrates through the left side of the main body and is slidably connected with the main body. The left side of the transmission shaft is fixedly connected with the right side of a control rod. The left side of the control rod is penetrated by a push rod. The push rod is slidably connected with the control rod. The push rod is fixedly connected with the right side of a spring A. By extending the control rod into the pipeline and starting the linear motor, the transmission shaft of the linear motor drives the control rod to extend into the pipeline.

[0004] However, this device still has some deficiencies. The method of achieving pipeline sealing through the mutual cooperation of multiple structures is relatively complex, and at the same time, the operation is inconvenient. Moreover, the method of detecting whether the pipeline leaks by injecting gas is not appropriate. Because when continuously injecting gas, the gas will continuously accumulate pressure. If there is a leak point in the pipeline, the high-intensity pressure will be concentrated at this point and discharged, and its pressure will cause secondary harm to the leak point of the pipeline, and then make the leak point larger.

Detailed Description of the Embodiments

[0022] Embodiment

[0023] Reference Figures 1 to 4, A rapid leak detection device for stainless steel pipes in this embodiment includes a support plate 1. A machine shell 2 is fixedly connected to the top end of the support plate 1. An electric cylinder 4 is installed at the bottom end inside the machine shell 2. The telescopic shaft of the electric cylinder 4 protrudes from the front side of the machine shell 2. Water outlet holes 5 are provided on the outer side of the telescopic shaft of the electric cylinder 4. A connecting block 6 is fixedly connected to the front side of the electric cylinder 4. A sealing rubber sheet 7 is threadedly connected to the front side of the connecting block 6. A sealing gasket 8 is fixedly connected to the front side of the machine shell 2. The sealing gasket 8 covers the front side of the machine shell 2. A water tank 3 is installed at the bottom end inside the machine shell 2. A water pump 9 is installed at the bottom end inside the machine shell 2. A water suction pipe 10 and a water outlet pipe 11 are installed on the outer side of the water pump 9. The water suction pipe 10 communicates with the inside of the water tank 3, and the water outlet pipe 11 communicates with the water outlet holes 5. A shell cover 15 is snap-connected to the top end of the machine shell 2. The shell cover 15 covers the top end of the machine shell 2. Since the telescopic shaft of the electric cylinder 4 is divided into two sections, the first section is in a stationary state, and the second section is sleeved inside the first section and can thus move back and forth. The water outlet pipe 11 of the water pump 9 is installed inside the first section of the telescopic shaft of the electric cylinder 4 and then communicates with the water outlet holes 5 on the second section. Thus, the situation where the water outlet pipe 11 is squeezed and distorted when the telescopic cylinder expands and contracts will not occur. When in use, start the electric cylinder 4 to push the sealing rubber sheet 7 into the pipe. The sealing rubber sheet 7 can seal the end of the pipe. The sealing gasket 8 on the front side of the machine shell 2 is attached to the head end of the pipe to quickly seal the pipe. Then the user starts the water pump 9. The water suction pipe 10 can suck the water in the water tank 3 and discharge it into the pipe through the water outlet pipe 11 and the water outlet holes 5 at the same time. After filling the pipe with water, it can be directly known whether there is a leak point in the pipe. After filling the pipe with water, if the pipe is in an overall sealed state, the pressure inside will prevent the water outlet pipe 11 from supplying water into the pipe. If there is a leak point, the water will directly flow out through the leak point. The water only needs to fill the pipe, so there will be no strong pressure, thus not causing secondary harm to the leak point of the pipe, and at the same time, it can also achieve the purpose of quickly detecting the leak point of the pipe.

A clamping block 16 matching the card slot 14 is fixedly connected to the bottom end of the cover 15. The clamping block 16 is clamped inside the card slot 14. The cover 15 is clamped to the top end of the casing 2 through the card slot 14 and the clamping block 16. A handle 19 is fixedly connected to the top end of the cover 15. The shape of the handle 19 is concave, and the shape of the corners of the handle 19 is arc-shaped. Due to the existence of the clamping block 16, the insertion of the clamping block 16 can effectively limit the position of the cover 15 and prevent it from shifting. The handle 19 is convenient for the user to grasp. When it is necessary to remove the cover 15, the clamping block 16 can be directly pulled out of the card slot 14 through the handle 19.

[0026] Reference Figure 1 , a rectangular opening 17 is provided at the top end of the cover 15. The rectangular opening 17 communicates with the inside of the casing 2. A transparent glass 18 is fixedly connected to the inside of the rectangular opening 17. The transparent glass 18 covers the inside of the rectangular opening 17. The position of the transparent glass 18 is symmetrical to the position of the electric cylinder 4. Due to the opening of the rectangular opening 17, the user can directly view the inside of the casing 2 through the transparent glass 18 without opening the cover 15, which is beneficial for the user to observe the operating condition of the equipment inside the casing 2 at all times and can effectively improve the safety of the operation of the equipment inside the casing 2.

[0027] Reference Figure 2 And Figure 3 , a water passing hole 20 is provided on one side of the casing 2. The water passing hole 20 communicates with the inside of the water tank 3. A sealing plug 21 is inserted into the inside of the water passing hole 20. The sealing plug 21 covers the inside of the water passing hole 20. A convex block 22 is fixedly connected to one side of the sealing plug 21. The shape of the corners of the convex block 22 is arc-shaped. Due to the existence of the sealing plug 21, the water passing hole 20 can be completely sealed to prevent the water source in the water tank 3 from flowing out. The convex block 22 is convenient for the user to grasp. When it is necessary to drain the water source later, the sealing plug 21 can be pulled out through the convex block 22.

[0028] Reference Figure 3 , legs 25 are fixedly connected to the bottom end of the support plate 1. The legs 25 are fixedly connected to the four sides of the bottom end of the support plate 1 near the corners. A protective frame 26 is fixedly connected to the bottom end of the support plate 1.

The power supply module 23 is electrically connected to the control module 24, the electric cylinder 4, and the water pump 9. The control module 24 is electrically controlledly connected to the electric cylinder 4 and the water pump 9. Due to the existence of the power supply module 23, the devices on the device can be effectively powered on, and the control module 24 can uniformly control these devices. It is more convenient and fast to control the operation of the entire device through the control module 24.

[0030] Principle of use and advantages: During use, start the electric cylinder 4 to push the sealing rubber sheet 7 into the pipeline. The sealing rubber sheet 7 can seal the end of the pipeline. The gasket 8 on the front side of the casing 2 is attached to the head end of the pipeline to quickly seal the pipeline. Then the user starts the water pump 9. The water suction pipe 10 can suck the water in the water tank 3, and at the same time discharge it into the pipeline through the water outlet pipe 11 and the water outlet hole 5. After filling the water source, it can be directly known whether there is a water leakage point in the pipeline. Because after the water source is filled, if the pipeline is in an overall sealed state, the pressure inside will cause the water outlet pipe 11 to no longer supply water into the pipeline. If there is a water leakage point, the water source will directly flow out through the water leakage point. The water source only needs to fill the pipeline, and thus there will be no strong pressure, so that the water leakage point of the pipeline will not be damaged secondly, and at the same time, the purpose of quickly detecting the water leakage point of the pipeline can be achieved. Due to the existence of the support legs 25, the bottom end of the support plate 1 can be effectively supported. The protective frame 26 can effectively limit the position of the rubber pad 27. The rubber pad 27 has good rubber anti-slip and rubber shock absorption capabilities, and thus can effectively improve the stability of the placement of the support plate 1. Because the sealing rubber sheet 7 is fixed by threads, when it needs to be disassembled later, just unscrew the screw hole 12, which is also beneficial for the user to maintain or replace the sealing rubber sheet 7 later. Due to the existence of the block 16, the insertion of the block 16 can effectively limit the position of the housing cover 15 and prevent it from shifting. The handle 19 is convenient for the user to grasp. When the housing cover 15 needs to be disassembled, just directly pull out the block 16 from the card slot 14 through the handle 19. Due to the opening of the rectangular opening 17, the user can directly view the inside of the casing 2 through the transparent glass 18 without opening the housing cover 15, which is beneficial for the user to observe the operating conditions of the devices inside the casing 2 at all times and can effectively improve the safety of the operation of the devices inside the casing 2. Due to the existence of the sealing plug 21, the water passing hole 20 can be completely sealed to prevent the water source in the water tank 3 from flowing out. The convex block 22 is convenient for the user to grasp. When the water source needs to be drained later, just pull out the sealing plug 21 through the convex block 22.
