Detailed Implementation

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0036] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0037] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0038] This application provides a waterproof and breathable sensor, such as... Figure 1 and Figure 2 As shown, the waterproof and breathable sensor includes a housing 1, a base 2, a waterproof and breathable part 3, and a sensor body 4. The housing 1 has a connecting hole 101 and a first receiving cavity 102. Wherein,

[0039] The connecting hole 101 communicates with the first receiving cavity 102 and extends to the edge of the outer shell 1.

[0040] The seat 2 has a detection cavity 201, at least a portion of which is located within the first receiving cavity 102.

[0041] The waterproof and breathable part 3 covers the side of the seat body 2 near the connecting hole 101 and connects the first receiving cavity 102 and the detection cavity 201.

[0042] At least a portion of the sensor body 4 is located within the detection cavity 201.

[0043] Understandably, the outer shell 1 provides support for the sensor body 4 and prevents soil from falling and obstructing gas flow, thus improving the stability of the sensor body 4. The connecting hole 101 allows sewage and leaked underground gas to pass through and enter the first receiving cavity 102. The waterproof and breathable part 3 connects the first receiving cavity 102 and the detection cavity 201, filtering sewage and gas entering the first receiving cavity 102, facilitating the entry of leaked gas into the detection cavity 201 for detection and identification by the sensor body 4. This allows for the detection of gas composition in moist soil and water, improving environmental adaptability.

[0044] In this embodiment, the outer shell 1 can be connected to the sensor body 4 by welding, bonding, bolting or snapping, thereby fixing the position of the sensor body 4.

[0045] In this embodiment, the waterproof and breathable part 3 has small holes with a diameter small enough to allow gas to pass through, while solids such as dust and mud and liquids such as water cannot pass through, thus achieving the filtering effect of solid impurities, water and gas.

[0046] In this embodiment of the application, the connecting hole 101 communicates with the first receiving cavity 102 and extends to the edge of the outer shell 1.

[0047] In this embodiment, the seat 2 can be bent to create a recess, forming a detection cavity 201. The extent to which the detection cavity 201 is located within the first receiving cavity 102 is affected by the seat 2; the more the seat 2 extends into the first receiving cavity 102, the larger the proportion of the detection cavity 201 within the first receiving cavity 102 generally is. Optionally, the seat 2 may be completely located within the first receiving cavity 102, in which case the detection cavity 201 is also completely located within the first receiving cavity 102.

[0048] In this embodiment, the waterproof and breathable part 3 covers the side of the base 2 near the connecting hole 101. After impurities such as water, mud, and sand enter the first receiving cavity 102, they need to pass through the waterproof and breathable part 3 before entering the detection cavity 201. Since the waterproof and breathable part 3 can block impurities such as water and mud and allow gas to pass through, it can act as a filter, thereby reducing the contamination of the sensor body 4 located in the detection cavity 201 by impurities. This helps the sensor body 4 to complete the gas detection.

[0049] In this embodiment, the waterproof and breathable part 3 can be a membrane structure.

[0050] In this embodiment, the sensor body 4 can detect gases such as methane and petroleum gas.

[0051] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the outer shell 1 includes a housing 11 and a first extension 12. The housing 11 has a connecting hole 101. The first extension 12 is connected to the housing 11 and forms a first receiving cavity 102. The seat 2 is connected to the first extension 12. At least a portion of the seat 2 extends into the first receiving cavity 102 through the opening of the first extension 12.

[0052] It is understandable that the first extension 12 can support the seat 2, which helps to fix the position of the seat 2 and enable the seat 2 to stably maintain the position of the detection cavity 201. This is beneficial for the sensor body 4 to complete the detection work in the detection cavity 201.

[0053] In this embodiment, the first extension 12 and the base 2 can be connected by means of bolting, welding, bonding or snap-fitting.

[0054] In this embodiment, the first extension 12 and the housing 11 can be connected by means of bonding, welding or bolting.

[0055] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the seat 2 includes an inner liner 21 and a support portion 22. The support portion 22 connects the first extension portion 12 and the inner liner 21. The inner liner 21 has a detection cavity 201 and extends into the first receiving cavity 102 through the opening of the first extension portion 12.

[0056] Understandably, the support portion 22 provides support for the inner liner 21, and the connection between the first extension portion 12 and the inner liner 21 maintains the stability of the inner liner 21. The inner liner 21, by forming the detection cavity 201, provides a detection environment for the sensor body 4. The inner liner 21 extends into the first receiving cavity 102 through the opening of the first extension portion 12, facilitating the entry of gas from the first receiving cavity 102 into the detection cavity 201 via the waterproof and breathable portion 3, thus aiding the sensor body 4 in completing the detection process.

[0057] In this embodiment, the support portion 22 can be connected to the side of the first extension portion 12 near the connecting hole 101, or it can be connected to the side of the first extension portion 12 away from the connecting hole 101.

[0058] In this embodiment, the first extension 12 can be connected to the support 22 by bolts. The bolts pass through the support 22 and form a threaded connection with the first extension 12. A sealing ring can be arranged between the first extension 12 and the supporting part to prevent impurities such as mud and sand in the first receiving cavity 102 from directly contacting the sensor body 4.

[0059] In this embodiment, the liner 21 can be made of a material with a certain degree of plasticity, and the detection cavity 201 is formed by bending the liner 21.

[0060] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the inner liner 21 has a mesh structure with mesh openings that connect the waterproof and breathable part 3 and the detection chamber 201.

[0061] Understandably, the mesh connects the waterproof and breathable part 3 and the detection chamber 201, allowing gas to pass through and enter the detection chamber 201. The inner liner 21 has a mesh structure, which helps improve the efficiency of gas passage through the inner liner 21, thus facilitating the sensor body 4 located inside the detection chamber 201 to complete the detection work.

[0062] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the outer casing 1 includes a second extension 13, which is connected to the support 22. The second extension 13 surrounds the opening of the first extension 12 and forms a second receiving cavity 103 with the support 22. The second receiving cavity 103 communicates with the opening of the first extension 12.

[0063] Understandably, the second extension 13 can be used to support the sensor body 4. The second extension 13 surrounds the opening of the first extension 12 and forms a second receiving cavity 103 with the support 22, which helps to limit the sensor body 4. The sensor body 4, which is limited in the second receiving cavity 103, can maintain the posture of extending into the detection cavity 201, so that the detection work can be completed.

[0064] In this embodiment, the second extension 13 may be annular. The depth of the second receiving cavity 103 is affected by the height of the second extension 13; the higher the height of the second extension 13, the deeper the second receiving cavity 103.

[0065] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the outer casing 1 includes a mounting portion 14, which is connected to the second extension portion 13 and is located within the second receiving cavity 103.

[0066] It is understandable that the mounting part 14 can be assembled with the sensor body 4 to improve the stability of the sensor body 4.

[0067] In this embodiment, the mounting part 14 may include an internal thread, and the sensor body 4 is assembled with the housing 1 by being threadedly connected to the internal thread.

[0068] In this embodiment, the mounting part 14 may also include a snap fastener, and the sensor body 4 is assembled with the housing 1 by snapping into the snap fastener.

[0069] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the waterproof and breathable sensor also includes a sleeve 5, which has a third receiving cavity. The sleeve 5 is connected to the outer shell 1, and the third receiving cavity is connected to the detection cavity 201.

[0070] Understandably, the sensor body 4 is generally elongated, and the outer shell 1 only covers a portion of the sensor body 4. However, the waterproof and breathable sensor of this application needs to be buried underground, which could easily lead to the sensor body 4 being contaminated through direct contact with the outside environment. The third receiving cavity of the sleeve 5 can accommodate and protect the sensor body 4, which is beneficial for the normal operation of the sensor body 4 and the completion of the detection work.

[0071] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the waterproof and breathable sensor also includes a bracket 6, which is located at both ends of the sleeve 5, and the bracket 6 is connected to the sleeve 5.

[0072] Understandably, the bracket 6 facilitates the connection of the sleeve 5 with other tools or allows it to be supported by other tools, thus improving the stability of the sleeve 5.

[0073] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, there are multiple connecting holes 101, and connecting holes 101 are distributed on the bottom and sides of the outer shell 1.

[0074] Understandably, the connecting holes 101 located at the bottom and sides of the outer casing 1 can improve the efficiency of underground leaked gas entering the first containment cavity 102, which is beneficial for the detection cavity 201 to form an environment for the sensor body 4 to detect.

[0075] In some embodiments of this application, the waterproof and breathable sensor includes a buoyancy part 7, which is connected to the sleeve 5.

[0076] Understandably, when a leak occurs in a pipe at the bottom of a body of water, such as a river, the sensor needs to perform the detection function underwater. If it cannot maintain a certain level of stability underwater, the detection effect will be weakened accordingly. This application uses the buoyancy part 7 to keep the sensor body 4 in a position close to the water surface, which facilitates the entry of leaked gas into the detection chamber 201 from all directions through the waterproof and breathable part 3, thereby improving the detection effect.

[0077] In this embodiment, the buoyancy part 7 can be an annular airbag structure. The buoyancy part 7 can be filled with a gas of density less than water, such as air, making the overall density of the waterproof and breathable sensor less than or equal to the density of the surrounding water. This helps the sensor body 4 maintain its position close to the water surface. The buoyancy part 7 can be fitted onto the outside of the sleeve 5, and through the limiting effect of the bracket 6, it can generate stable buoyancy on the sleeve 5 and bracket 6 in the water, allowing the sensor body 4 to remain close to the water surface. The buoyancy part 7 can be fitted onto the outside of the sleeve 5 and abut against it. The pressure generated by this abutment creates friction between the buoyancy part 7 and the sleeve 5. This friction hinders relative displacement between the buoyancy part 7 and the sleeve 5, thus forming a connection between the buoyancy part 7 and the sleeve 5.

[0078] In this embodiment, the buoyancy part 7 can be made of a material with a density less than that of water, so that the overall density of the waterproof and breathable sensor of this application is less than or equal to the density of the water in which it is located.

[0079] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, there is a gap between the waterproof and breathable part 3 and the bottom and side of the first receiving cavity 102.

[0080] It is understandable that the gap can be filled with water or air in the soil, which can increase the contact area between the waterproof and breathable part 3 and the air in the water or soil, thereby increasing the efficiency of the leaked gas entering the detection chamber 201 through the waterproof and breathable part 3, so as to improve the detection effect of the sensor body.

[0081] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
