Description

Technical Field

[0001] The utility model relates to a vehicle for emergency ventilation of tunnels and corridors, belonging to the technical field of emergency equipment. Background Art

[0002] As national urban development demands increased urban resilience, management efficiency, and urban disaster prevention capabilities, emerging urban areas have explored and developed the construction of underground pipeline corridors. With the promotion of underground pipeline corridors, there is a growing demand for specialized equipment for emergency rescue and accident handling in underground pipeline corridors, tunnels, and other environments. Pipeline corridors are relatively confined spaces, and air circulation between different corridors relies on fan systems. In the event of a temporary power outage or disaster damage, air circulation will no longer be provided, and fire prevention and control functions will be lost in the event of a fire or toxic gas leak. Therefore, it is particularly important to develop a mobile ventilation device that can perform emergency rescue operations.

[0003] Emergency ventilation vehicles can be used for emergency ventilation operations in closed and semi-closed spaces such as underground pipeline corridors and tunnels. They can replace the outside air or designated construction gas with the air in the closed space through the air duct, thereby meeting the air requirements of the space for emergency rescue operations.

[0004] These functions not only reflect the practicality and necessity of underground corridor construction, but also reflect its important position in modern urban construction. Utility Model Content

[0029] The position adjustment mechanism 5 includes a telescopic cylinder 501, a lower mounting platform 502, a tilting platform 503, a rotary reducer 504 and a square flange frame 505. An opening is provided on the steel plate on the rear side of the connecting beam 201. The telescopic cylinder 501 is tilted at the opening.

[0031] The tail of the off-road chassis 1 and the rear of the generator set 3 are both provided with a lighting system 6 .

[0032] The operation method of the utility model comprises the following steps:

[0033] ① The off-road chassis vehicle 1 drives to a designated location in the corridor or tunnel;

[0034] ② Adjust the jet fan 4 to a suitable position through the position adjustment mechanism 5;

[0035] ③ Turn on the jet fan 4. There are two operating modes when the jet fan 4 is operating. One is to inject air or flame-retardant gas into the corridor or tunnel through the jet fan 4 to form positive pressure to replace the gas in the corridor or tunnel through the air duct; the other is to form negative pressure through reversing suction to extract the gas in the space, so as to avoid the harm caused by the overflow of toxic and harmful gases, and at the same time transport the toxic and harmful gases to the designated filtering device.

[0036] After the ventilation vehicle arrives at the designated location, it is determined whether to install an air duct according to demand. A flame-retardant air duct or a flame-retardant air belt is laid on the inspection passage beside the road in the corridor or tunnel to form an air duct. The flame-retardant air duct or the flame-retardant air belt is fixed to the air outlet of the jet fan 4 through a clamp. The motor of the jet fan 4 drives the fan blades to form a wind flow, which transmits the air or flame-retardant gas along the air duct to the designated location of the corridor or tunnel to replace the gas in the corridor or tunnel.

[0037] Refer to the attached Figure 1 、 6 In this embodiment, the off-road chassis vehicle 1 adopts an off-road professional chassis and is equipped with large-pattern tires to ensure that the vehicle has sufficient passability and can pass through damaged roads after a disaster. Figure 2 The off-road chassis 1 is equipped with a frame beam 2, which is divided into two layers. The top layer is the load-bearing beam 202, and the bottom layer is the connecting beam 201. The load-bearing beam 202 is covered with lentil-patterned steel plates. The load-bearing layer is divided into front and rear ends. The generator set 3 is mounted on the top of the front end, and the position adjustment mechanism 5 and jet fan 4 are mounted on the top of the rear end.

[0038] Refer to the attached Figure 3 The generator set 3 is a multifunctional complex, housing a diesel generator set 301 and an exterior soundproofing hood 302 for rain and dust protection. The soundproofing hood 302 has an access door on the driver's side. A control box 303 with a rainproof door is located in the lower right corner of the driver's side. A toolbox is located to the right of the co-pilot seat, housing a flame-retardant air duct and / or air duct.

[0039] The diesel generator set 301, the silent shield 302, the control box 303 and other components are all well-known and commonly used equipment in the art.

[0040] The jet fan 4 is a special fan for emergency ventilation vehicles, which is a well-known and commonly used equipment in the field. It drives the fan blades through a motor to form a wind flow, and transmits the air along the wind tube to a designated location. The jet fan is selected to have the characteristics of large air volume, high wind speed and high wind pressure. After the wind tube is laid through the maintenance passage beside the road to form an air duct, it can effectively promote the flow of air in the narrow corridor. There are two operating modes during operation. One is to inject air or flame-retardant gas into the tunnel or corridor through the fan to form a positive pressure to replace the gas in the tunnel or corridor through the air duct. The second is to form a negative pressure by reversing the suction to extract the toxic and harmful gases in the corridor or tunnel to the outside world, so as to avoid the concentration of toxic and harmful gases in the enclosed space of the corridor or tunnel being too high, which endangers the safety of people in the corridor or tunnel.

[0041] Refer to the attached Figure 4 and 5 The position adjustment mechanism 5 is used to adjust the azimuth angle of the jet fan 4 to adapt to the direction of the jet fan under different working conditions. The position adjustment mechanism 5 of the present utility model has two functional embodiments.

[0042] The position adjustment mechanism 5 includes a telescopic cylinder 501, a lower mounting platform 502, a flipping platform 503, a rotary reducer 504 and a square flange frame 505. The rear end of the bearing layer of the load-bearing beam 202 is fixedly mounted with the lower mounting platform 502. A square hole is opened on the lentil pattern steel plate on one side of the lower mounting platform 502. The telescopic cylinder 501 is arranged obliquely in the square hole. The bottom of the telescopic cylinder 501 is connected to the connecting beam 201 through a double ear plate mechanism. The top of the cylinder rod of the telescopic cylinder 501 is connected to the flipping platform 503 through an ear plate and a pin. A lower mounting platform 502 is provided below the flipping platform 503. The two are rotatably connected by connecting ear plates and pins. The upper end face of the flipping platform 503 is connected to the bottom flange of the rotary reducer 504 through a flange. The upper flange of the rotary reducer 504 is connected to the bottom flange of the square flange frame 505. The jet fan 4 is fixed on the arc frame of the square flange frame 505.

[0043] The turning platform 503 is formed by welding a rectangular frame and a steel plate from top to bottom. The top of the cylinder rod of the telescopic cylinder 501 is connected to the bottom of the steel plate through an ear plate and a pin.

[0044] The width of the flip platform 503 is greater than the width of the lower mounting platform 502. A vertical ear plate 5031 is provided on the outer side of the bottom of the flip platform 503, and a horizontal ear plate 5021 is provided on the outer side of the lower mounting platform 502. The horizontal ear plate 5021 and the vertical ear plate 5031 are arranged perpendicular to each other and are connected by a pin shaft to form a double ear plate mechanism.

[0045] In the first embodiment, the rotary reducer 504 can perform a rotary motion to enable the jet fan 4 to rotate 360 ​​degrees along the rotary axis of the rotary reducer, thereby adjusting the horizontal azimuth angle of the air outlet of the jet fan 4.

[0046] In the second embodiment, the pin shaft in the double-ear plate mechanism is used as the rotation center, and the vertical angle between the jet fan 4 and the frame beam 2 can be changed through the telescopic cylinder 501. Specifically, the lever of the telescopic cylinder 501 is extended to drive the jet fan 4 to flip outward and extend beyond the frame beam 2, thereby adjusting the vertical azimuth inclination angle of the air outlet of the jet fan 4.

[0047] In this embodiment, the vertical angle change of the jet fan 4 is subject to certain limitations, and its change trajectory is restricted by the mechanical structure to avoid interference with its own structure.

[0048] Preferably, in order to ensure that the jet fan 4 rotates along the two rotation axes without interfering with the frame beam 2, a double detection interlocking relationship is provided, and the vertical angle change at different horizontal positions is controlled by sensors.

[0049] The slewing reducer 504 is driven by a servo motor, offering high torque and low speed. The high-speed ratio of the slewing reducer 504 further reduces the rotation speed of the jet blower 4, preventing safety accidents. The telescopic cylinder 501 can be either an electric cylinder or a hydraulic cylinder. During operation, all electric devices are powered by their own generators. When hydraulically driven, a small hydraulic station is added to the vehicle.

[0050] The lighting system 6 can be installed on the frame beam 2 and the generator set 3 to achieve multi-angle and wide-range lighting.
