Description

Technical Field

[0001] The invention relates to the technical field of support cabins, and in particular to a pressurized support cabin for on-site tunnel command. Background Art

[0002] Tunnel construction and rescue sites often face complex and changing environmental conditions, such as high temperature, high pressure, low oxygen, and the presence of toxic and hazardous gases. These harsh environments not only pose a serious threat to the health and safety of frontline workers, but also bring huge challenges to on-site command and dispatch and emergency rescue work.

[0003] At present, the command in the tunnel mainly relies on ordinary command vehicles or temporary command stations. These traditional command facilities have many shortcomings in the special environment of the tunnel: First, the traditional command facilities lack good air pressure regulation function and cannot maintain the balance of pressure inside and outside the cabin in high-pressure or low-pressure environments. When the air pressure changes in the tunnel, it is easy to cause the pressure inside the command cabin to be unstable, affecting the normal operation of the equipment and the health of personnel. Secondly, the existing facilities lack effective thermal insulation measures. In high or low temperature environments, it is difficult to maintain a suitable temperature in the cabin, affecting the work efficiency and comfort of the commander. Thirdly, in the face of sudden accidents such as tunnel collapse, the structural strength and pressure resistance of traditional command facilities are insufficient, unable to resist external physical damage, and it is difficult to ensure the continuity of command work in time. In addition, the mobility of existing command facilities is limited, and it is difficult to adjust the position in time to adapt to the complex and changeable terrain and operation requirements inside the tunnel. At the same time, there is a lack of perfect toxic gas filtration and disinfection functions, and it is impossible to provide a safe air environment for internal personnel.

[0004] In summary, the existing technology is difficult to meet the comprehensive needs of tunnel on-site command for pressurization support, temperature control, structural strength and mobility flexibility in special environments. Therefore, there is an urgent need for a pressurization support cabin that can adapt to the complex environment of the tunnel, with functions such as air pressure regulation, thermal insulation, strong structure, flexible mobility and toxic gas filtration, so as to improve the safety and effectiveness of tunnel on-site command. Summary of the invention

[0037] The detailed connection means are well-known technologies in the art; the support cabin is brought to the tunnel construction site or emergency rescue site by means of transportation, and the travel device (crawler or electric roller 23) of the pressurized support cabin is used to move it to a predetermined position and adjust it to a stable state, and the height of the cabin is adjusted according to the height difference of the ground in the tunnel by using a lifting device, and the lifting motor 17 is started. The driving end of the lifting motor 17 drives the lead screw 20 to rotate and then drives the threaded sleeve 21 to make the lifting frame 19 slide up and down in the fixed seat 18, and then adjust the height to ensure that the cabin is placed firmly and maintains a convenient access to the operation area. After the personnel arrive outside the cabin, they enter the pressure-maintaining porch pipe 10, close the outer sealing door 11, and start the spray disinfection device in the closed porch to disinfect outsiders. The personnel carry out preliminary disinfection and protection (usually whole body clothing and equipment), the constant pressure machine 12 is started, the air pressure inside and outside the porch pipe 10 is balanced, and the pressure inside the porch is gradually and slowly adjusted to be consistent with the pressure inside the cabin to ensure that the personnel can safely adapt to the environmental pressure. After the pressure balance is completed, the personnel open the inner sealed door 11 and formally enter the cabin. After entering, the cabin environment can be monitored through the central system, including basic indicators such as temperature, air pressure, oxygen concentration and toxic gas detection instruments. According to the commander's requirements, comfort equipment (such as air conditioning temperature, lighting, etc.) can be adjusted to meet the needs of long-term work. The commander maintains real-time communication and data sharing with the external construction team or rescue team through the communication structure in the cabin, and conducts efficient scheduling and command issuance.

[0038] When it is necessary to perform operations directly outside the cabin, such as isolating and operating dangerous valves, operating underwater valves in dangerous environments, or other situations requiring auxiliary operations, the mobile platform 30 moves on the guide rail 29 and can be driven by a linear motor. The hinge connector 31 is then rotated by the built-in direction motor to adjust the direction of the robotic arm. The first motor 35 and the second motor 36 then drive the first rocker arm 32 and the second rocker arm 33 to swing for direction adjustment. The operating head 34 can be installed with structures of different models and functions as needed to meet the usage requirements in different situations.

[0039] With the help of the digital function of the central control system, real-time on-site data (such as abnormal air pressure, changes in temperature and humidity, concentration of toxic gases, etc.) can be collected to assist decision-making; the alarm mechanism can be activated when necessary. If the oxygen concentration in the tunnel environment is abnormal, the booster air supply machine 4 and the oxygen supply machine 6 are started to provide high-pressure fresh air for the personnel in the cabin. If the outside temperature inside the tunnel is too high or too low, the constant temperature system is started, and the temperature and humidity in the cabin are adjusted to a comfortable level through the combined action of the inner insulation cabin 8 and the constant pressure device; at the same time, the low-pressure area structure reduces the heat loss or conduction in the cabin. If there is a toxic gas leak outside, ensure that the cabin door is closed and the air filter function of the air supply fan is increased to prevent external harmful gases from entering and maintain the cleanliness of the cabin air. The dynamic backup battery 28 is used as an auxiliary power source to ensure the normal operation of key functional modules (such as communication devices, constant pressure machine 12, etc.), and can maintain operation even in the event of power outages or major failures. After completing the command or operation tasks, the personnel inside the cabin must leave safely through the pressure-maintaining corridor pipe 10. After opening the inner sealed door 11 and entering the corridor pipe 10, close the inner sealed door 11, and the constant pressure machine 12 gradually adjusts the pressure difference between the inside of the corridor and the outside of the cabin until the corridor pressure is consistent with the atmospheric pressure outside the cabin. After opening the outer sealed door 11, leave the corridor and enter the area outside the tunnel. When passing through the outer corridor pipe 10, the personnel leaving the cabin can choose to start the secondary disinfection spray function to thoroughly clean up the pollutants that may be carried and ensure the safety of the internal environment of the cabin.
