[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0030] Please see Figure 1-4 An emergency treatment device for chemical pipeline leaks includes a first clamp 1 and a second clamp 2. The top of the first clamp 1 is provided with a rectangular groove 3, and the opposite side walls of the rectangular groove 3 are provided with sliding grooves 4 along the height direction. A V-shaped groove 5 is provided at the center of the bottom of the rectangular groove 3.

[0031] The second clamp 2 is an arc shape that fits the outer wall of the pipe, and its inner wall is provided with an elastic sealing layer 6 and an expansion sealing layer 7 stacked from the inside to the outside.

[0032] The two ends of the second clamp 2 are provided with slide bars 8 that are adapted to the slide groove 4. The second clamp 2 is slidably disposed in the rectangular groove 3 through the slide bars 8.

[0033] The first clamp 1 has a strip-shaped operation window 9 on the upper front side that communicates with the slide 4. The height of the operation window 9 is greater than the height of the slide 8. The operation window 9 is used for loading or unloading the slide 8.

[0034] A clamping block 10 is slidably disposed inside the slide groove 4 and above the slide bar 8;

[0035] Electric telescopic rods 11 are installed on both sides of the top of the first clamp 1. The telescopic ends of the electric telescopic rods 11 extend into the corresponding sliding grooves 4 and are fixedly connected to the clamping blocks 10.

[0036] In this embodiment: After a chemical pipeline leak is detected, the first clamp 1 is placed below the leaking area, so that the V-groove 5 fits against the outer wall of the pipeline; through the strip-shaped operating window 9 on the front side of the first clamp 1, the sliding strips 8 at both ends of the second clamp 2, which are adapted to the sliding groove 4, are aligned with the sliding groove 4, and the second clamp 2 is slid upward along the sliding groove 4 until it tightly wraps around the leaking area of ​​the pipeline. The arc shape of the second clamp 2 fits the outer wall of the pipeline and can completely cover the leak; the elastic sealing layer 6 on the inner wall of the second clamp 2 is made of fluororubber composite material, which utilizes its elasticity and chemical corrosion resistance to fill the uneven parts of the pipeline surface and fit tightly against the outer wall of the pipeline to form a preliminary sealing barrier to prevent the initial leakage of chemical media; if the leaking media or moisture in the surrounding environment comes into contact with the expansion sealing layer 7 (water-swellable rubber)... The adhesive layer (6) rapidly absorbs water and expands, filling the tiny gaps between the elastic sealing adhesive layer 6 and the pipe, as well as the minor aging gaps in the elastic sealing adhesive layer 6, significantly improving the sealing effect. The electric telescopic rods 11 on both sides of the top of the first clamp 1 extend, pushing the pressing block 10 in the slide groove 4 downwards, pressing the second clamp 2 tightly onto the pipe. The elastic pad 13 at the bottom of the pressing block 10 buffers the pressure, preventing damage to the second clamp 2 and making the pressure distribution more uniform, ensuring that the elastic sealing adhesive layer 6 and the expanding sealing layer 7 are fully and tightly attached to the outer wall of the pipe. At the same time, the pressure sensor 14 embedded in the elastic pad 13 monitors the pressure in real time and transmits the signal to the controller 15. The controller 15 controls the electric telescopic rod 11 according to the preset pressure value and the actual pressure signal to achieve precise adjustment of the sealing pressure.

[0037] As a technical optimization of this utility model, a rubber pad 12 is embedded in the V-groove 5.

[0038] In this embodiment, a rubber pad 12 is embedded in the V-groove 5. The elasticity and sealing properties of the rubber pad 12 can better fill the gap between the V-groove 5 and the pipe, preventing the medium from leaking from the contact area between the clamp and the pipe, thus enhancing the sealing performance of the device. At the same time, the buffering effect of the rubber pad 12 can increase the stability of the clamp on the pipe and reduce the impact of factors such as pipe vibration on the sealing effect.

[0039] As a technical optimization of this utility model, the elastic sealant layer 6 is a fluororubber composite material layer with a Shore hardness of 70-80A and a thickness of 3-5mm.

[0040] In this embodiment: the fluororubber composite material has good chemical corrosion resistance, high temperature resistance and elasticity, and can maintain stable sealing performance in chemical media and complex environments; and the appropriate hardness and thickness ensure that the elastic sealing layer 6 can effectively fill the unevenness of the pipe surface, and has sufficient strength and durability, thereby improving the sealing reliability and service life of the device.

[0041] As a technical optimization of this utility model, the expansion sealing layer 7 is a water-swellable rubber layer with a water-swellable ratio of not less than 300%.

[0042] In this embodiment: when the device is installed on the leaking pipe, if moisture comes into contact with the expansion sealing layer 7, it will expand rapidly, further filling any tiny gaps that may exist between the elastic sealing layer 6 and the pipe, significantly improving the sealing effect; and it can further enhance the sealing performance of the device on the basis of the elastic sealing layer 6, especially suitable for situations where the leaking medium may contain moisture or the surrounding environment is humid, improving the adaptability of the device under complex working conditions.

[0043] As a technical optimization of this utility model, the bottom of the clamping block 10 is provided with an elastic pad 13, and a pressure sensor 14 is embedded in the elastic pad 13; a controller 15 is installed on the first clamp 1, and the controller 15 is electrically connected to the pressure sensor 14 and the electric telescopic rod 11, and the controller 15 is provided with an operation button 16.

[0044] In this embodiment, by setting an elastic pad 13 at the bottom of the clamping block 10 and embedding a pressure sensor 14 therein, and by electrically connecting the controller 15 with the pressure sensor 14 and the electric telescopic rod 11, real-time monitoring and precise control of the sealing pressure are achieved. The controller 15 can automatically adjust the extension and retraction of the electric telescopic rod 11 according to the signal fed back by the pressure sensor 14, so that the clamping block 10 applies appropriate pressure to the second clamp 2, ensuring that the device is always in the best sealing state. At the same time, the setting of the operation button 16 facilitates manual control by the operator, improving the flexibility and convenience of device operation.

[0045] As a technical optimization of this utility model, a movable pressure-boosting block 17 is provided in the V-groove 5; an adjusting screw 18 is provided on the outside of the first clamp 1, one end of the adjusting screw 18 is provided with a force-applying part 19, and the other end is threaded through the first clamp 1 and rotatably connected to the pressure-boosting block 17; a guide rod 20 is fixedly connected to the pressure-boosting block 17, and the guide rod 20 slides through the first clamp 1.

[0046] In this embodiment, the operator can manually adjust the clamping force of the clamping block 10 on the pipeline by rotating the adjusting screw 18 to adapt to pipelines of different diameters and with different leakage conditions. The guide rod 20 ensures the stability of the movement of the clamping block 10 and improves the accuracy and reliability of the adjustment.

[0047] As a technical optimization of this utility model, the second clamp 2 is made of 316L stainless steel with a thickness of 8-12mm, and the surface is treated with enamel for corrosion protection.

[0048] In this embodiment: 316L stainless steel has excellent corrosion resistance and strength, and can be used for a long time in chemical environment without being corroded or damaged; and the appropriate thickness ensures that the second clamp 2 has sufficient strength to withstand the pressure of the medium inside the pipeline; the enamel anti-corrosion treatment further enhances the corrosion resistance of the second clamp 2, extends its service life, reduces the maintenance cost of the device, and improves the reliability of the device in chemical production environment.

[0049] Working principle and usage process of this utility model:

[0050] First, place the first clamp 1 near the pipe leak point, aligning the V-groove 5 with the pipe. Then, align the slide bar 8 of the second clamp 2 with the slide groove 4 through the operation window 9, and slide the second clamp 2 into the rectangular groove 3 along the slide groove 4 until the second clamp 2 is tightly fitted to the pipe leak point. At this time, activate the electric telescopic rod 11. The telescopic end of the electric telescopic rod 11 pushes the clamping block 10 downward, and the elastic pad 13 at the bottom of the clamping block 10 contacts the second clamp 2 and gradually applies pressure. The pressure sensor 14 monitors the clamping force in real time and transmits the data to the controller 15. The controller 15 adjusts the clamping force according to the preset pressure value via the operation button. 16. Control the extension and retraction of the electric telescopic rod 11 to ensure that the clamping force reaches the appropriate range, so that the elastic sealing layer 6 and the expansion sealing layer 7 of the second clamp 2 are tightly attached to the outer wall of the pipe to achieve a preliminary seal. If the leaking medium contains moisture, the water-swellable rubber layer will expand rapidly to further fill the leak gap and enhance the sealing effect. When it is necessary to further fix the pipe, the clamping block 10 in the V-groove 5 can be moved towards the pipe by rotating the force application part 19 of the adjusting screw 18 to perform secondary clamping on the pipe. The guide rod 20 ensures that the pressure-assisting block 17 moves smoothly, thereby improving the stability and sealing of the connection between the entire device and the pipe.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model.
