[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 4As shown, this utility model provides a high-efficiency ventilation and purification device for tunnel construction, including a purification component 1. An air inlet duct 2 is fixedly connected to the front and rear sides of the duct 1. Several inlets are arranged in a circular array on the outer surface of the front and rear air inlets duct 2. This design increases the air intake area, allowing more air to enter the purification component 1. A fan is fixedly connected to the right side of the air inlet duct 2. The fan consists of a drive motor and fan blades. When the fan operates, it draws in surrounding air, sucking air from the tunnel into the air inlet duct 2 through the inlets and then into the purification component 1. An air outlet 3 is fixedly connected to the front and rear sides of the right side of the purification component 1. The purified air is discharged from the air outlet 3. Two L-shaped mounting plates 4 are fixedly connected to the front and rear sides of the upper surface of the purification component 1. The L-shaped mounting plates 4 are used to install the purification component 1 on the top of the tunnel.

[0027] Example 2: Figures 1 to 4 As shown, the purification component 1 includes a housing 11. A power supply can be installed on the outer surface of the housing 11, and the power supply, wires, fan, and motor are electrically connected. A partition plate is fixedly connected to the middle of the inner wall of the housing 11, dividing the interior of the housing 11 into different areas. The left side is the dust entry area, and the right side is the dust removal area. A motor is fixedly connected to the right side of the middle of the partition plate. The output shaft of the motor passes through the interior of the partition plate and is fixedly connected to a gear 12. Gear rings 13 are meshed with the front and rear sides of the outer surface of the gear 12. Dust collection screens 14 are fixedly connected to the inner walls of the front and rear gear rings 13. The motor drives the gear 12 to rotate, and the gear 12 then drives the front and rear gear rings 13 to rotate. The dust collection screens 14 rotate accordingly. During the rotation, the dust collection screens 14 can simultaneously filter dust and other impurities in the air.

[0028] Mounting plates 15 are provided on the outer surfaces of both the front and rear dust collection nets 14. A block is fixedly connected to the lower surface of the mounting plate 15, and the surface of the block is fixedly connected to the surface of the partition plate. A brush 151 is fixedly connected to the right side of the mounting plate 15. The surface of the brush 151 overlaps with the surface of the dust collection net 14. When the dust collection net 14 rotates, the brush 151 can continuously clean the dust on the surface of the dust collection net 14, preventing dust from clogging the dust collection net 14 and ensuring the purification and dust removal effect.

[0029] Two collection blocks 16 are fixedly connected to the left side of the partition plate in a mirror-like manner. The inclined surfaces of the two collection blocks 16 form a V-shape. The two collection blocks 16 are in a right-angled triangle state. The dust swept down by the brush 151 moves downward and slides down along the inclined surfaces of the collection blocks 16, eventually falling into the collection box 5 below.

[0030] The inner annular array of the gear ring 13 has several interconnected dust outlets 131. These outlets prevent dust accumulation after cleaning. A sleeve 132 is fixedly connected to the right side of the gear ring 13. The outer surface of the sleeve 132 extends through the interior of the partition plate and is movably connected. A retaining ring 133 is fixedly connected to the outer surface of the sleeve 132. The gear ring 13 and the retaining ring 133 prevent the sleeve 132 from easily falling off during rotation.

[0031] A collection box 5 is located below the purification component 1. The collection box 5 is used to collect dust that slides off the collection block 16. A door 6 is located on the left side of the collection box 5, which is convenient for staff to open the collection box 5 to clean the dust. Connecting components 7 are located on the upper front and rear sides of the collection box 5. The connecting components 7 are used to connect the collection box 5 to the purification component 1. A square pipe 17 is fixedly connected through the middle of the left side of the box body 11. The outer surface of the square pipe 17 is inserted into the inside of the collection box 5. This design allows the dust swept down from the dust collection net 14 to fall more directly into the collection box 5 through the square pipe 17, reducing the dust dispersion in the air and improving the collection efficiency.

[0032] The motor and the fan in the air inlet duct 2 do not work simultaneously. When the fan is working, the motor in the dust cleaning structure stops working, and when the motor is working, the fan stops working. Two timer controllers JZF-10A can be installed on the outer surface of the housing 11 to facilitate timing control of the motor and fan to complete the start and stop operations. The timer controller, motor and fan are electrically connected to the power supply through wires.

[0033] Example 3: Figures 1 to 4As shown, the connecting component 7 includes a T-shaped plate 71 and a blocking block 72. Connecting blocks are movably connected to the left and right sides of the T-shaped plate 71 in the vertical direction. The surfaces of the connecting blocks are fixedly connected to the surface of the purification component 1. A groove is formed in the center of the front of the blocking block 72, and the interior of the groove overlaps with the outer surface of the T-shaped plate 71. The surface of the blocking block 72 is fixedly connected to the surface of the collection box 5. A rod 74 is inserted into the center of the lower surface of the T-shaped plate 71. The rod 74 restricts the position of the T-shaped plate 71, allowing for movement. A circular block 75 is fixedly connected through the center of the outer surface of the rod 74. A fixing plate 73 is slidably connected through the lower part of the outer surface of the rod 74. The surface of the 3 is fixedly connected to the surface of the collection box 5. A spring 76 is sleeved on the outer surface of the insertion rod 74. The spring 76 allows the insertion rod 74 to be reset after being pressed and released. The upper and lower ends of the spring 76 are fixedly connected to the surfaces of the circular block 75 and the fixing plate 73. When installing the collection box 5, the square pipe 17 is inserted into the inside of the collection box 5 by moving the collection box 5 upward, and the T-shaped plate 71 is rotated into the groove of the blocking block 72. At the same time, the worker releases the insertion rod 74, which moves upward and is inserted into the inside of the T-shaped plate 71 under the action of the retracted spring 76, thus restricting the position of the T-shaped plate 71 and realizing a reliable connection between the collection box 5 and the purification component 1.

[0034] Working principle: In use, the air is first drawn in through the inlet of the air inlet duct 2, and the air inlet duct 2 is designed to adsorb the surrounding air over a large area. The adsorbed air enters the purification component 1 and is blocked by the dust collection net 14, thus completing the air purification. The purified air is then discharged through the air outlet 3.

[0035] When it is necessary to clean the surface dust of the dust collection screen 14, the motor is started and the gear 12 is driven to rotate slowly, thereby rotating the front and rear gear rings 13 and driving the dust collection screen 14 to rotate. While the dust collection screen 14 is rotating, the brush 151 in the mounting plate 15 cleans the dust on the surface of the rotating dust collection screen 14. After the dust on the dust collection screen 14 is cleaned, the motor is turned off, so that the sleeve 132 and the dust collection screen 14 stop rotating. The dust inside the gear ring 13 falls through the ash outlet 131 and enters the collection box 5 through the collection block 16 and the square pipe 17, thereby completing the dust collection.

[0036] When a large amount of dust accumulates inside the collection box 5 and needs to be cleaned, the worker is moved close to the device by using a lifting device, and then the spring 76 is compressed by pressing down the plug rod 74. As the plug rod 74 moves downward and separates from the inside of the T-shaped plate 71, the worker flips the T-shaped plate 71 and separates it from the blocking block 72. The collection box 5 is then moved downward to complete the disassembly, and the door 6 is opened to clean the dust inside.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
