[0036] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Embodiment 1

[0037] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown,

[0038] A leakproof cover comprises a leakproof membrane 1 and two pipe connectors 2. The leakproof membrane 1 encloses a receiving cavity and has two openings 3. The openings 3 are sealed and connected to the pipe connectors 2. One end of the leakproof membrane 1 connected to the pipe connectors 2 has a fastener 4. The fastener 4 is used to fasten the leakproof membrane 1 and the pipe connectors 2 so that the leakproof membrane 1 and the pipe connectors 2 form a closed cavity 5 that wraps the pipe 6.

[0039] Through the above technical solution, two pipe connectors 2 are arranged on the pipe 6 to be observed, and the leak-proof membrane 1 and the pipe connector 2 form a containing cavity surrounding the pipe 6, and the fastener 4 is used to tighten the leak-proof membrane 1 and the pipe connector 2, so that the pipe connector 2 tightly wraps the pipe 6, and the leak-proof membrane 1 is also close to the pipe connector 2, forming a closed cavity 5 with the leak-proof membrane 1 and the pipe connector 2 wrapping the pipe 6. When the pipe 6 leaks, some colorless and odorless gases or fluids will penetrate into the closed cavity 5, further causing the leak-proof membrane 1 to deform, or be detected by the detection device, so that it is easy to observe the leakage and convenient for people to deal with the leakage as soon as possible.

[0040] As a specific implementation method of the improvement,

[0041] The pipeline connector 2 includes a flexible connector 7 and a sealing sheet 8 . The sealing sheet 8 is located in the closed cavity 5 and fits with the flexible connector 7 .

[0042] Through the above technical scheme, the flexible connector 7 can undergo a certain deformation. When the fastener 4 is tightened, the flexible connector 7 is easier to fit the leak-proof membrane 1, and the sealing sheet 8 fits with the flexible connector 7. The sealing sheet 8 is made of foam rubber. The sealing sheet 8 has a higher hardness than the flexible connector 7. The sealing sheet 8 can support the part that fits with the flexible connector 7. When tightened, the flexible connector 7 is deformed, but the sealing sheet 8 will not be deformed or will be slightly deformed, so that the tightening effect of the fastener 4 is more obvious.

[0043] As a specific implementation method of the improvement,

[0044] The flexible connector 7 has a fitting portion 9 , which wraps the pipe 6 . The fitting portion 9 has a raised portion 10 surrounding the fitting portion 9 , and one side of the raised portion 10 fits the sealing sheet 8 .

[0045] Through the above technical solution, the fitting portion 9 of the flexible connector 7 is tightly attached to the pipe 6, thereby increasing the fitting surface with the pipe 6, and the raised portion 10 surrounding the fitting portion 9 is concentric and has an outer diameter larger than the fitting portion 9, so that the leak-proof membrane 1 can wrap the raised portion 10, and the raised portion 10 can support space, so that the closed cavity 5 has sufficient space, and the fitting portion 9 increases the fitting surface with the pipe 6, thereby enhancing the sealing effect.

[0046] As a specific implementation method of the improvement,

[0047] The fastener 4 is a connecting belt 11, a buckle 12, a fastener 13, and a strap 14. A plurality of straps 14 are provided on the leak-proof membrane 1. The connecting belt 11 passes through the strap 14. One end of the connecting belt 11 is connected to the buckle 12, and the other end is connected to the fastener 13. The buckle 12 is buckled with the fastener 13.

[0048] Through the above technical scheme, a number of loops 14 are arranged around the positions where the two ends of the leak-proof membrane 1 need to be tightened, and the connecting belt 11 passes through the number of loops 14. The two ends of the connecting belt 11 are respectively connected to the buckle 12 and the fastener 13. When connected, one end of the connecting belt 11 passes through the Japanese buckle 15 on the buckle 12, and the other end of the connecting belt 11 is connected to the fastener 13. When the buckle 12 and the fastener 13 are connected, they can be fastened by the Japanese buckle on the buckle 12. With this method, the fastener 4 is more stable and not easy to fall off.

[0049] As a specific implementation method of the improvement,

[0050] The fastener 4 is a cable tie 16 or a clamp 17 .

[0051] Through the above technical solution, the cable tie 16 or the clamp 17 is used for tightening, and the cable tie 16 or the clamp 17 is easy to obtain in daily life, and has the characteristics of convenient acquisition, simple structure and low cost.

[0052] As an improved specific implementation, the anti-leakage membrane 1 has a zipper 18 , and the zipper 18 extends from the pipe connector 2 to another pipe connector 2 .

[0053] Through the above technical solution, the zipper 18 is opened when the leak-proof membrane 1 is not installed. When it needs to be installed, the leak-proof membrane 1 is put on the pipe connector 2, and the zipper 18 is closed at the same time. An airtight zipper 18 is used here. Since the airtight zipper already belongs to the prior art, this embodiment will not be described in detail. After the zipper 18 is closed, the sealing of the closed cavity 5 is maintained. Due to the use of the zipper 18, the leak-proof membrane 1 is easy and convenient to install, and the procedure for disassembly is convenient.

[0054] As an improved specific implementation, the protrusion 10 is bonded to the sealing sheet 8 using a sealant 19 .

[0055] Through the above technical solution, the sealant 19 used in the raised portion 10 is already in the prior art and will not be further explained in this embodiment. The sealant currently used in the prior art can already achieve complete sealing, so the sealant 19 is applied to the raised portion 10 to achieve better sealing, and the sealing sheet 8 is glued to the raised portion 10 to be more stable, thereby achieving a better sealing effect.

[0056] As an improved specific implementation, the flexible connector 7 has a cutout 20 , and the cutout 20 extends from the fitting portion 9 to the raised portion 10 . The cutout 20 is used for the flexible connector 7 to wrap the pipe 6 .

[0057] Through the above technical solution, the flexible connector 7 has a cutout 20 and can be easily sleeved on the pipe 6 during installation.

[0058] As an improved specific implementation, the flexible connecting member 7 is made of foam material.

[0059] Through the above technical solution, foaming materials such as sponge, rubber and plastic, glass fiber cotton, and silicone cotton are easily obtained in daily life, so that the flexible connecting member 7 is easy to obtain and manufacture. Embodiment 2

[0060] Reference Figure 3 , Figure 4 As shown,

[0061] As an improved specific implementation, the leak-proof membrane 1 has an air connection pipe 21 , the air connection pipe 21 is connected to an expansion ball 22 , and the gas in the leak-proof membrane 1 is guided to the expansion ball 22 .

[0062] Through the above technical solution, since the leak-proof membrane 1 is connected to the air connection pipe 21, when leakage occurs, the gas flows out from the closed cavity 5 and passes to the expansion ball 22, which is a balloon. Therefore, the expansion ball 22 will expand, making the leakage observable to the naked eye.

[0063] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
