Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a tunnel air purification device. Background Art

[0002] A tunnel is an engineering structure buried in the ground, which is a form of human utilization of underground space. The structure of a tunnel includes two parts: a main building and auxiliary equipment. The main building consists of a tunnel body and a portal, and the auxiliary equipment includes refuge bays, fire-fighting facilities, emergency communication, and water-proof and drainage facilities. Long tunnels also have special ventilation and lighting equipment; when building a tunnel, a purification device for purifying air will be installed in the tunnel to filter the automobile exhaust in the tunnel.

[0003] The prior art such as the utility model with the publication number of CN208512276U discloses a tunnel air purification device. The patent uses a housing provided with an air inlet and an air outlet. The air in the housing cavity flows through the air inlet, a dust removal filter bag, a photosensitive catalytic reaction base, a fan, and the air outlet in sequence. Plate bodies are arranged in parallel on both sides of the reaction base, and catalytic lamps are evenly distributed on the plate bodies. A number of the reaction base and the plate bodies are alternately distributed in sequence; the floating dust in the tunnel is filtered by the filter bag, and the dust is collected in the filter bag to achieve the effect of dust removal. The filter bag can collect more dust and can extend the maintenance time to the greatest extent. The harmful gas after dust removal undergoes a photosensitive catalytic reaction through the catalytic reaction base irradiated by a parallel light source, thereby reducing the content of harmful gas and achieving the effect of effectively purifying air. Combining the two air purification methods of dust removal and photosensitive catalysis into one not only saves space but also can effectively treat various polluting chemical waste gases, solving the problems that although the existing equipment can reduce the pollution of waste gas, it cannot remove dust, the dust accumulation is serious, and the gas with dust passing through the photocatalytic area adheres to the photocatalyst, seriously affecting the photocatalytic reaction.

[0004] The inventor found in daily work that during the process of filtering tunnel air with the help of an air purification device, there is a problem that the reaction base used in the existing purification device such as the above is installed inside the device. When maintenance personnel perform maintenance operations on the reaction base, because the reaction base is installed inside the device, the maintenance personnel must disassemble the housing through relatively cumbersome operations to take out the reaction base for cleaning. At the same time, due to the high installation position of the device, when maintenance personnel perform operations, it is not conducive for the staff to operate tools, thereby limiting the disassembly efficiency of the staff.

By arranging the connecting component and the auxiliary component, it is convenient for the staff to disassemble the reaction base, thereby reducing the problems of high installation position of the equipment and difficult disassembly, and further improving the maintenance efficiency of the equipment.

[0023] Next, specifically describe the specific settings and functions of its connection component 7 and auxiliary component 8.

[0024] In this implementation scheme: the auxiliary component 8 includes an installation box 81. The installation box 81 is fixedly connected to the side surface of the side baffle 72. A wedge-shaped pin 82 is slidably connected to the inner wall of the installation box 81. A limiting spring 83 is fixedly connected to the side surface of the wedge-shaped pin 82. The limiting spring 83 is fixedly connected to the inner wall of the installation box 81. A T-shaped buckle 84 is fixedly connected to the surface of the outer shell 1. The wedge-shaped pin 82 is inserted into the inner wall of the T-shaped buckle 84. A connection frame 85 is fixedly connected to the surface of the wedge-shaped pin 82. A linkage rod 86 is rotatably connected to the inner wall of the connection frame 85. A turning hole is formed in the side surface of the linkage rod 86. A handle 87 is installed on the inner wall of the turning hole of the linkage rod 86.

[0025] Specifically, the number of the limiting springs 83 is two. The two limiting springs 83 are symmetrically arranged about the wedge-shaped pin 82. The limiting spring 83 is sleeved on the surface of the connection frame 85. The position of the wedge-shaped pin 82 can be restricted by the limiting spring 83, so as to ensure that the position of the wedge-shaped pin 82 can be limited within the T-shaped buckle 84.

[0026] Specifically, a through hole is formed in the surface of the installation box 81. The connection frame 85 is slidably connected to the inner wall of the through hole. The connection frame 85 penetrates through the through hole. The connection frame 85 abuts against the surface of the side baffle 72.

[0027] In this embodiment: Through the cooperation of the connecting frame 85 and the mounting box 81, the deformation direction of the limiting spring 83 can be guided, thereby reducing the probability of the limiting spring 83 shifting during deformation.

[0028] Specifically, the number of linkage pull rods 86 is four, and the four linkage pull rods 86 are diagonally arranged with respect to the side baffle 72. Through the cooperation of the linkage pull rods 86 and the grip 87, the disassembly operation of the staff can be facilitated and the disassembly efficiency of the staff can be improved.

[0029] In this embodiment: The connection assembly 7 further includes a connection plate 71. The connection plate 71 abuts against the inner wall of the housing 1.

The limiting plate 73 abuts against the surface of the reaction group 5. A clamping plate 74 is fixedly connected to the side surface of the side baffle 72. A rubber gasket 75 is fixedly connected to the side surface of the clamping plate 74. The rubber gasket 75 abuts against the surface of the reaction group 5.

[0030] In this embodiment: Through the cooperation of the side baffle 72 and the connection plate 71, the opening part of the housing 1 can be blocked, thereby ensuring that the housing 1 forms a sealed structure.

[0031] Specifically, the limiting plate 73 abuts against the surface of the housing 1. The number of the limiting plates 73 is multiple, and the multiple limiting plates 73 are horizontally arranged with respect to the connection plate 71. The position of the reaction group 5 can be preliminarily limited through the limiting plate 73, and the installation spacing of the reaction group 5 can be defined, thereby ensuring that the spacing between the reaction groups 5 is the same.

[0033] In this embodiment: Through the cooperation of the clamping plate 74 and the rubber gasket 75, the reaction group 5 can be clamped in cooperation with the limiting plate 73, thereby realizing the assembly of the reaction group 5.

[0034] Working principle: When the reaction base 5 needs to be maintained, one hand presses against the side baffle 72, and the grip 87 is pulled. The grip 87 cooperates with four linkage rods 86 to pull the connecting frames 85 at the four corners. The connecting frame 85 is stressed to pull the wedge-shaped pin 82. The wedge-shaped pin 82 presses against the limit spring 83 under force, and the limit spring 83 deforms under force. The wedge-shaped pin 82 disengages from the T-shaped buckle 84 under the pull of the connecting frame 85. When the wedge-shaped pin 82 moves to the maximum spacing, the grip 87 is continuously pulled. The grip 87 cooperates with the linkage rod 86, the connecting frame 85 and the wedge-shaped pin 82 to pull the installation box 81. The installation box 81 is stressed to pull the side baffle 72. The side baffle 72 cooperates with the connecting plate 71 to pull the limit plate 73 and the clamping plate 74. The limit plate 73 and the clamping plate 74 cooperate with the rubber gasket 75 to pull out the reaction base 5 in the housing 1, thus realizing the disassembly operation of the reaction base 5. By setting the connection assembly 7 and the auxiliary assembly 8, it is convenient for the staff to disassemble the reaction base 5, and then reduces the problems of the high installation position of the equipment and the large disassembly difficulty, and further improves the maintenance efficiency of the equipment.
