Industrial sites often experience vibrations from various mechanical equipment and vehicles, which are transmitted to the monitoring and analysis cabin, affecting the normal operation and measurement accuracy of the precision monitoring equipment inside. The existing cabin structure is not well-designed for vibration damping, failing to effectively buffer and absorb vibration energy, leading to reduced equipment stability and reliability, increased maintenance costs and failure rates, and shortened equipment lifespan.

These vibrations are transmitted to the monitoring and analysis cabin and affect the normal operation and measurement accuracy of the precision monitoring equipment inside the cabin.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an explosion-proof flue gas monitoring and analysis cabin, comprising:

A pressure chamber is sleeved on the outside of the pressure plug. A pressure relief hole is opened on the pressure chamber. The pressure relief hole is connected to the external environment and is used to adjust the pressure inside the pressure chamber.

[0010] As a preferred embodiment of the explosion-proof flue gas monitoring and analysis cabin described in this utility model, the explosion-proof structure includes an explosion-proof wall, which is composed of an outer explosion-proof steel plate and an inner fireproof and heat-insulating board, with flame-retardant material filling the space between the two layers.

[0028] Example

[0029] Reference Figures 1-4 As an embodiment of the present invention, an explosion-proof flue gas monitoring and analysis cabin is provided, comprising: a main body unit 100 and a shock-absorbing unit 200.

[0030] The main unit 100 includes a cabin body 101 and an explosion-proof structure. The bottom of the cabin body 101 is provided with an anti-slip base plate 103.

[0031] The anti-slip base plate 103 is made of high-strength steel plate and has an upward-turned edge 104 on the edge, the height of which is 20mm-30mm.

[0032] A drain outlet 105 is provided on the upward-turned edge 104, and a drain pipe 106 is provided on the anti-slip base plate 103. The drain pipe 106 is made of PVC material, and its diameter matches that of the drain outlet 105. The drain pipe 106 is connected to the drain outlet 105.

[0033] The shock absorption unit 200 includes a top connecting seat 201 and a bottom connecting seat 202. The top connecting seat 201 is fixedly connected to the anti-slip base plate 103. A prefabricated foundation 203 is provided at the bottom of the bottom connecting seat 202. Pressure plugs 204 are fixedly connected to the sides of the top connecting seat 201 and the bottom connecting seat 202 that are close to each other. A pressure chamber 205 is sleeved on the outside of the pressure plug 204. A pressure relief hole 206 is provided on the pressure chamber 205. The pressure relief hole 206 communicates with the external environment and is used to adjust the pressure inside the pressure chamber 205.

[0034] The explosion-proof structure includes an explosion-proof wall 102, which is composed of an outer explosion-proof steel plate and an inner fireproof and heat-insulating board, with flame-retardant material filling the space between the two layers.

[0035] The shock absorption unit 200 also includes a connecting frame 207 fixedly installed on the pressure chamber 205. The connecting frame 207 has a frame 208 on both sides. A slider 209 is slidably arranged inside the frame 208. A groove 212 is opened on the frame 208. The top of the slider 209 extends into the groove 212. A connecting rod 210 is movably connected between the top connecting seat 201 and the bottom connecting seat 202 and the slider 209, respectively.

[0036] A spring 211 is provided inside the frame 208. One end of the spring 211 contacts the side of the slider 209 away from the pressure chamber 205, and the other end contacts the inner wall of the frame 208.

[0037] During operation, the Explosion-Proof Wall 102 plays a crucial role in explosion protection. Its double-layer structure provides excellent protection. The outer layer of explosion-proof steel plate, with its high strength, directly withstands the powerful shockwave generated by an explosion, effectively weakening its destructive force. The inner layer of fireproof insulation board not only blocks flames but also provides thermal insulation, preventing flames and high temperatures from harming monitoring equipment and personnel inside the cabin. Furthermore, the flame-retardant rock wool filling between the two layers further enhances fire resistance and cushioning performance. When an explosion occurs, the flame-retardant rock wool absorbs some of the blast energy, slows the propagation speed of the shockwave, and prevents the spread of flames, providing a reliable safety barrier for the cabin's interior, thus effectively resisting blast shockwaves and flames.

[0038] The design of the anti-slip base plate 103 also fully considers the actual usage environment. Its upward-curving edge 104 is of moderate height, reliably preventing external debris, such as pebbles, leaves, and small particles, from entering the cabin and causing damage to the equipment or affecting its normal operation. Simultaneously, the drainage outlet 105 on the upward-curving edge 104 works in conjunction with the drainage pipe 106 installed on the anti-slip base plate 103 to form an efficient drainage system. In case of rainfall, rainwater flows along the surface of the anti-slip base plate 103 to the drainage outlet 105. Because the drainage pipe 106 is made of PVC material, its diameter matches the drainage outlet 105, and the connection is tight, rainwater can quickly drain from the cabin through the drainage pipe 106, preventing water from stagnating at the bottom of the cabin for extended periods. This prevents water from corroding the cabin's foundation structure and equipment, ensuring the long-term stable use of the cabin.

[0039] In terms of vibration damping, the device features a two-stage damping mechanism. In the first stage, external vibrations are transmitted to the bottom connecting seat 202 via the precast foundation 203. At this time, the pressure plug 204 begins to compress the internal air within the pressure chamber 205, causing a rapid increase in pressure within the chamber. To balance the pressure, the pressure within the chamber is released to the external environment through the pressure relief hole 206. This pressure release effectively absorbs high-frequency vibration energy, minimizing the impact of high-frequency vibrations on the cabin and protecting the precision monitoring equipment inside from interference.

[0040] During the secondary vibration damping process, after the primary damping has completed the initial absorption of high-frequency vibrations, the remaining low-frequency vibrations will cause the linkage rod 210 to push the slider 209 to slide along the slide groove 212. The sliding of the slider 209 within the slide groove 212 is constrained by the spring 211 inside the frame 208. When the slider 209 slides, the spring 211 will compress and deform. The spring 211 has good elasticity and can absorb the energy of low-frequency vibrations during compression and deformation, converting it into the elastic potential energy of the spring 211 and storing it. As the vibration weakens, the spring 211 will gradually return to its original shape, slowly releasing the stored energy. In this way, low-frequency vibrations are further absorbed, ensuring that the equipment inside the cabin can operate stably even in a low-frequency vibration environment.

[0041] Furthermore, the hinged design of the linkage 210 and the slider 209 plays a crucial role in limiting movement. This hinged design ensures that vibration energy is transmitted along a specific direction during vibration, preventing structural instability due to uneven stress during vibration. It allows the entire damping system to absorb vibration energy while maintaining structural stability and reliability, providing a safer and more stable operating environment for the equipment inside the cabin.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
