[0003] However, there are still many problems in the prior art in the process of detecting chemical leakage. Summary of the invention

[0004] The technical problem solved by the present invention is to provide a liquid leakage detection system to improve the range and effectiveness of liquid leakage detection and reduce the cost of liquid leakage detection.

[0005] In order to solve the above problems, the technical solution of the present invention provides a liquid leakage detection system, including: a cofferdam structure, the cofferdam structure has a cofferdam cavity; and a plurality of liquid leakage sensors, the liquid leakage sensors are arranged in the cofferdam cavity.

[0008] Optionally, the cofferdam edge includes: an inner ring plate, and the inner ring plate is a whole-surface structure.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] In the leakage detection system of the technical solution of the present invention, the leaking chemicals can be contained and collected by the cofferdam structure to prevent the leaking chemicals from scattering and being unable to be effectively detected. After the leaking chemicals are contained and collected for detection, not only can the detection range be increased, but also the effective detection of the leakage sensor can be ensured, and at the same time, the layout of the leakage sensor can be reduced, effectively reducing the leakage detection cost.

[0024] As described in the background art, there are still many problems in the prior art in the process of detecting chemical leakage, which will be described in detail below.

[0025] At present, most of the explosion-proof liquid leakage sensors that have obtained relevant explosion-proof certificates in China are single-piece structures, and there are no relevant sensor structures in the form of strips or belts. Therefore, in order to effectively detect or monitor chemical leakage, multiple liquid leakage sensors are added for detection, which increases the investment cost of detection, and if the liquid leakage sensor is not placed in a good position, it may be difficult to detect chemical leakage.

[0026] On this basis, the present invention provides a leakage detection system, which can contain and collect leaking chemicals through the cofferdam structure to prevent the leaking chemicals from spreading everywhere and being unable to be effectively detected. After the leaking chemicals are contained and collected for detection, not only can the detection range be increased, but also the leakage sensor can be effectively detected, and at the same time, the layout of the leakage sensor can be reduced, effectively reducing the leakage detection cost.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order or relative importance between these entities or operations.

[0029] Figure 1 is a structural schematic diagram of a liquid leakage detection system according to an embodiment of the present invention; Figure 2 yes Figure 1A schematic structural diagram of a portion of the cofferdam edge and the anti-corrosion layer in the leakage detection system of the illustrated embodiment.

[0030] Please refer to Figure 1 A liquid leakage detection system includes: a cofferdam structure 10, wherein the cofferdam structure 10 has a cofferdam cavity 11; and a plurality of liquid leakage sensors 20, wherein the liquid leakage sensors 20 are arranged in the cofferdam cavity 11.

[0031] The cofferdam structure 10 can be used to contain and collect leaking chemicals, preventing them from spreading and being unable to be effectively detected. After the leaking chemicals are contained and collected for detection, not only can the detection range be increased, but also the leakage sensor 20 can be effectively detected, and at the same time, the layout of the leakage sensor 20 can be reduced, effectively reducing the leakage detection cost.

[0032] It can be understood that the function of the cofferdam structure 10 is to contain and collect leaking chemicals. Therefore, the cofferdam structure 10 needs to have a closed structure with a top opening. The purpose of the top opening is to allow chemical equipment to be placed on the cofferdam structure 10, and the closed structure ensures that after the chemical equipment leaks, the cofferdam structure 10 can directly receive and contain and collect the leaked chemicals.

[0033] Please continue to refer to Figure 1 In some embodiments, the cofferdam structure 10 includes: a cofferdam bottom plate 101, and a cofferdam edge 102 fixedly connected to the cofferdam bottom plate 101; wherein the cofferdam edge 102 forms a closed annular structure, and the cofferdam bottom plate 101 seals the bottom opening of the annular structure to form the cofferdam cavity 11.

[0034] Please continue to refer to Figure 1 In some embodiments, the cofferdam bottom plate 101 includes: a flat portion 101a, a slope portion 101b connected to the flat portion 101a, and a ditch portion 101c connected to the slope portion 101b; the liquid leakage sensor 20 is disposed in the ditch portion 101c. The flat portion 101a is used to place chemical equipment to ensure the stability of the placement of the chemical equipment.

[0035] By providing the slope portion 101b, the flow of leaked chemicals can be easily collected in the ditch portion 101c. Since the ditch portion 101c collects the largest amount of leaked chemicals, the leakage sensor 20 is provided in the ditch portion 101c to improve the effective detection of the leakage sensor 20, while reducing the layout of the leakage sensor 20 and reducing the leakage detection cost.

[0036] Please refer to Figure 2In some embodiments, the cofferdam edge 102 includes an inner ring plate 102a, and the inner ring plate 102a is a whole surface structure. The inner ring plate 102a with a whole surface structure can effectively reduce the number of joints, thereby improving the sealing performance of the inner ring plate 102a.

[0037] Please continue to refer to Figure 2 In some embodiments, the cofferdam edge 102 further includes: an outer ring plate 102b fixedly connected to the inner ring plate 102a. The overall stability of the cofferdam edge 102 can be effectively improved by adding the outer ring plate 102b.

[0038] In some embodiments, the thickness of the inner ring plate 102a and the outer ring plate 102b is 1 mm to 3 mm; the spacing between the inner ring plate 102a and the outer ring plate 102b is 5 mm to 30 mm. The edge 102 of the cofferdam is only used to contain and collect the leaked chemicals, and the amount of the leaked chemicals is not large, so the inner ring plate 102a and the outer ring plate 102b only need to be thinner plates to reduce the detection cost.

[0039] Please continue to refer to Figure 2 In some embodiments, it further includes: an anti-corrosion layer 13 coated on the surface of the cofferdam structure 10. The chemicals used for leakage are corrosive to a certain extent. The general plate is easily damaged by the corrosion of the chemicals, and thus the sealing of the cofferdam structure 10 cannot be guaranteed. Therefore, by coating the anti-corrosion layer 13 on the surface of the cofferdam structure 10, the corrosion caused by the leaking chemicals to the cofferdam structure 10 can be reduced, thereby protecting the cofferdam structure 10. It should be noted that the specific selection of the anti-corrosion layer 13 needs to be based on the type of chemicals.

[0040] In some embodiments, since the outer ring plate 102b is usually not in contact with the leaking chemicals, in order to reduce the detection cost, the outer ring plate 102b may not be coated with the anti-corrosion layer 13. The cofferdam bottom plate 101 and the inner ring plate 102a are in direct contact with the leaking chemicals, so the cofferdam bottom plate 101 and the inner ring plate 102a need to be coated with the anti-corrosion layer 13.

[0041] In some embodiments, the material of the cofferdam structure 10 includes: metal material; the leakage sensor 20 is electrically connected to the cofferdam structure 10. Specifically, the cofferdam bottom plate 101 and the cofferdam edge 102 are both made of metal material. Since the leakage sensor 20 is an electronically controlled product and has a grounding requirement, if the leakage sensor 20 is grounded in the form of additional wiring, the wiring will be corroded and damaged if it comes into contact with the leaking chemicals. Therefore, by selecting a metal material for the cofferdam structure 10, the grounding requirement of the leakage sensor 20 can be met, and at the same time, the additional wiring and grounding of the leakage sensor 20 can be avoided.

[0042] In some embodiments, the cofferdam structure 10 is made of stainless steel.

[0043] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
