[0037] Please see the attached Figure 1 -Attached Figure 3 This embodiment relates to a monitoring instrument primarily for well chamber gas leak monitoring. This instrument is used to promptly obtain information about gas leaks within the well chamber, thereby ensuring the safety of well operations. Specific detection methods and monitoring principles can refer to existing technologies, such as combustible gas detection, odorization, drainer discharge volume determination, and indirect detection. Combined with intelligent monitoring systems and advanced monitoring equipment, these methods can achieve real-time monitoring and early warning of well chamber gas leaks. This embodiment will not further elaborate on these aspects.

[0038] The monitor includes a shell 1, a light guide 2, a light source 3, a first protective member 4 and a second protective member 5, wherein the shell 1 is provided with a light-transmitting area 11; the light source 3 is arranged inside the shell 1, and the light guide 2 is arranged inside the shell 1, and the light emitted by the light source 3 can pass through the light-transmitting area 11 through the light guide 2; the first protective member 4 is attached to the side of the light-transmitting area 11 away from the light guide 2, and the first protective member 4 is a light-transmitting structure; the second protective member 5 is clamped between the light guide 2 and the shell 1.

[0039] In this embodiment, the housing 1 is made of plastic or metal. For example, aluminum alloy, stainless steel, or ABS plastic can be used, all of which have good impact resistance and corrosion resistance. The housing 1 includes an upper shell and a lower shell, which are assembled by snapping together and formed into a complete rectangular box structure using a detachable connection method such as snap connection or screw connection. The inner cavity of the housing 1 is integrated with various components for realizing the function of monitoring leaked gas. The light source 3 is arranged inside the housing 1. The light source 3 can be an LED light source integrated on a PCB board. The light source 3 is used to generate a light signal and use the light guide 2 to guide the light, so that the operator can easily obtain relevant information, such as whether the monitor is working normally or whether the Bluetooth connection is successful. When the operator observes the light signal, he can directly and quickly obtain effective information and take corresponding measures to ensure safety.

[0040] The light guide 2 can be made of materials such as organic glass, polycarbonate, PVC, acrylic resin, epoxy resin and translucent acrylic plate. The light guide 2 can guide the light signal of the light source 3 to the translucent area 11 of the shell 1 to facilitate the operator to view. The translucent area 11 is the area on the surface of the shell 1 for transmitting light. Translucent glass or translucent plate can be directly embedded in the position of the shell 1, or the shell 1 can be directly made of translucent material, so that the shell 1 forms an integrated structure.

[0041] Furthermore, the first protective member 4 is directly attached to the outer surface of the light-transmitting area 11. At the same time, in order to ensure that the first protective member 4 does not block light, the first protective member 4 is also a light-transmitting structure. Specifically, a highly light-transmitting film can be used. A film with a 3M adhesive backing with an IP68 protection grade is bonded to the light-transmitting area 11. The film has a certain degree of waterproofness, thereby preventing water molecules from penetrating into the interior of the housing 1 through the light-transmitting area 11, causing the components inside the monitor to be damaged by moisture and affecting the life of the instrument. Since the first protective member 4 is attached to the outer surface of the light-transmitting area 11, in order to prevent the first protective member 4 from falling off over time, thereby further causing leakage in the position of the light-transmitting area 11, causing a short circuit in the main control board, and affecting the normal operation of the entire instrument, the present application further provides a second protective member 5. The second protective member 5 can be a waterproof member to avoid failure of the first protective member 4, further improve the protective performance, and ensure the working stability and service life of the components inside the monitor.

[0042] Optionally, a mounting boss 12 is protruding inwardly inside the housing 1 , a mounting hole is provided on the mounting boss 12 , the light guide 2 includes a first light guide portion 21 , the first light guide portion 21 is located in the mounting hole, and the first protective member 4 covers the mounting hole.

[0043] A rectangular mounting boss 12 is provided within the housing 1. The mounting boss 12 can be fixed to the inner wall of the housing 1 as an independent part by snapping or screwing, or it can be directly molded integrally with the housing 1 using a mold. The specific method can be selected based on a comprehensive consideration of manufacturing cost and processability, and is not specifically limited in this embodiment. A mounting hole is provided on the mounting boss 12. The mounting hole is a cylindrical hole. The first light guide portion 21 of the light guide 2 is a cylindrical light guide column. The diameter of the first light guide portion 21 is slightly smaller than the diameter of the mounting hole to facilitate the insertion of the first light guide portion 21 into the mounting hole. The mounting hole actually connects the interior and exterior of the housing 1. The waterproof film of the first protective member 4 is provided on the mounting hole to prevent moisture from penetrating through the mounting hole into the interior of the housing 1. Directly leading the first light guide portion 21 outward can increase the intensity of the light output and reduce light loss, thereby improving the brightness of the visible light and providing sufficient safety for underground workers.

[0044] Furthermore, the light guide 2 further includes a mounting portion 22 , which is pressed against the mounting boss 12 , and the mounting portion 22 is connected to the mounting boss 12 via a connecting assembly 23 .

[0045] In this embodiment, the mounting portion 22 is plate-shaped, with one side of the mounting portion 22 directly pressing against the mounting boss 12. The connecting assembly 23 can be fixed to the mounting boss 12 using rivets or a threaded structure. Of course, a latching protrusion can also be provided on the edge of the mounting portion 22, and a latching groove can be provided at a corresponding position on the mounting boss 12 to allow the mounting portion 22 and the mounting boss 12 to engage and cooperate, achieving rapid installation. The mounting portion 22 provides a vertical limit for the installation of the light guide 2, ensuring the accuracy of the installation position.

[0046] Preferably, the connecting assembly 23 includes a plurality of screws 231 and washers 232 sleeved on the screws 231 . The mounting portion 22 is provided with connecting holes, and the screws 231 pass through the connecting holes and are threadedly connected to the mounting boss 12 .

[0047] In this embodiment, two screws 231 are used for fastening. These screws 231 are symmetrically arranged on either side of the axis of the first light guide 21 to ensure uniform and balanced force. To prevent damage to the light guide 2 during screwing, washers 232 are used to separate the heads of the screws 231 from the mounting portion 22. Specifically, the mounting portion 22 is provided with a through-hole through which the screws 231 pass and are screwed to the mounting boss 12, providing a convenient connection and easy disassembly.

[0048] Optionally, the second protective member 5 is a sealing ring, which is disposed around the first light guide portion 21 and is squeezed between the mounting boss 12 and the mounting portion 22 .

[0049] In this embodiment, the second protective member 5 is a sealing ring arranged around the outer periphery of the first light guide part 21. The sealing ring has a certain elasticity. When the screw 231 is tightened to fix the light guide member 2, the light guide member 2 will squeeze the sealing ring to deform it, thereby further improving the sealing performance. Even if moisture passes through the mounting hole, it will still be blocked by the sealing ring, effectively improving the waterproof performance and ensuring the stability and life of the instrument.

[0050] Furthermore, a limiting groove 121 is provided on the mounting boss 12 , and a portion of the sealing ring structure is placed in the limiting groove 121 , and a portion of the sealing ring protruding from the limiting groove 121 presses against the mounting portion 22 .

[0051] In this embodiment, retaining groove 121 is an arcuate annular groove that matches the arcuate outer wall of the sealing ring. After the sealing ring is placed in retaining groove 121, part of its structure protrudes from the mounting boss 12, ensuring that the extrusion force can smoothly deform the sealing ring, thereby ensuring sealing. The provision of retaining groove 121 effectively ensures the assembly of the sealing ring, ensuring stable and efficient assembly.

[0052] Optionally, the light guide 2 further includes a second light guide portion 24 , which is columnar, one end of which is connected to an end of the mounting portion 22 away from the first light guide portion 21 , and the other end of which is arranged opposite to the light source 3 .

[0053] In this embodiment, the second light guide portion 24 is also a cylindrical light guide column. The second light guide portion 24 is larger than the first light guide portion 21 in length and diameter, and is used to ensure that the light generated by the light source 3 is smoothly transmitted to the first light guide portion 21 through the second light guide portion 24, thereby reducing light loss.

[0054] Optionally, the mounting portion 22 and the second light guide portion 24 are an integrated structure.

[0055] In this embodiment, the mounting portion 22 and the second light guide portion 24 are an integrated structure and can be manufactured by an integrated molding method to reduce component costs.

[0056] Furthermore, the mounting portion 22 and the first light guide portion 21 are an integrated structure.

[0057] In this embodiment, the three parts of the entire light guide 2, the first light guide part 21, the second light guide part 24 and the mounting part 22 are an integrated structure and can be made of the same material through injection molding to reduce costs.

[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
