[0002] Ventilation, also known as air exchange, is the use of mechanical or natural methods to deliver enough fresh air into the indoor space, while expelling the dirty air that does not meet the hygiene requirements, so that the indoor air meets the hygiene requirements and the needs of the production process. The various facilities in the building that complete the ventilation work are collectively called ventilation equipment. When exhausting air, the internal air needs to be discharged to ensure the freshness of the internal air.

[0003] The ventilation units used in subway stations are generally installed in the walls of subway entrances. An installation hole is reserved on the wall of the subway entrance, and then the ventilation units are installed in the installation hole.

[0026] The invention discloses a subway ventilation unit with good buffering.

[0027] Reference Figures 1 to 5 , a subway ventilation unit with good buffering, including a mounting base plate 1, which is fixedly connected to the bottom surface of the ventilation unit 6 by anchor bolts. Four supporting legs 11 are fixedly connected to the bottom surface of the mounting base plate 1, and the connecting line of the four supporting legs 11 on the horizontal plane forms an isosceles trapezoid. Four slide rails 2 are fixedly connected to the bottom surface of the mounting hole 7 by anchor bolts, and the four slide rails 2 correspond to the four supporting legs 11 one by one, and each slide rail 2 is provided with a slide groove 21 suitable for the movement of the supporting leg 11. A first shock absorbing assembly 3 is provided on the supporting leg 11, and the first shock absorbing assembly 3 is connected to the slide rail 2; a second shock absorbing assembly 4 is provided on the bottom surface of the mounting hole 7, and the second shock absorbing assembly 4 is connected to the top surface of the ventilation unit 6.

[0028] During operation, the bottom of the ventilation unit 6 is damped by the first damping component 3, and the top and the entire ventilation unit 6 are damped by the second damping component 4. The first damping component 3 cooperates with the second damping component 4 to improve the buffering performance of the ventilation unit 6 and reduce the possibility of vibration being transmitted to the subway entrance. At the same time, the slide rail 2 can facilitate the rapid positioning and movement of the ventilation unit 6, thereby improving installation efficiency.

[0029] Specifically, the first shock absorbing assembly 3 is provided with four groups, which are respectively connected to the four supporting legs 11. The first shock absorbing assembly 3 includes rollers 31, sleeves 32 and shock absorbing pads 33. There are two rollers 31 in each group of the first shock absorbing assembly 3. The two rollers 31 are located on both sides of the supporting leg 11 along the width direction of the slide rail 2, and are both rotatably connected to the supporting leg 11. A rubber ring 311 is fixedly connected to the surface of each roller 31. The rubber ring 311 is suitable for contacting the top surface of the slide rail 2, so that the roller 31 rolls on the slide rail 2, thereby facilitating the supporting leg 11 to slide in the slide groove 21. The cooperation between the slide groove 21 and the supporting leg 11 facilitates the guiding of the supporting leg 11. The sleeves 32 include a top plate 321 and two side plates 322. The top plate 321 and the two side plates 322 are integrally formed. The shock absorbing pad 33 is fixedly connected to the bottom surface of the top plate 321 and is suitable for contacting the top surface of the slide rail 2. The top plate 321 is fixedly connected to the supporting leg 11. In this embodiment, two sleeves 32 are provided and are located on both sides of the support leg 11 along the length direction of the slide rail 2. Shock-absorbing plates are fixed on both sides of the support leg 11 along the width direction of the slide rail 2, and the shock-absorbing plates are suitable for contacting the side walls of the slide groove 21. The shock-absorbing pad 33 and the shock-absorbing plate are both made of rubber, and the rubber ring 311, the shock-absorbing pad 33 and the shock-absorbing plate cooperate to reduce the hard contact between the ventilation unit 6 and the bottom surface of the installation hole 7, so as to absorb the vibration generated by the operation of the ventilation unit 6 and reduce the possibility of vibration transmission to the subway entrance. At the same time, the shock-absorbing pad 33, the shock-absorbing pad 33 and the rubber ring 311 are all arranged on the support leg 11, which is more convenient and quicker than the traditional solution in which the buffer module is installed on the bottom surface of the installation hole 7.

[0030] A limiting groove 22 is provided on the side wall of the slide rail 2. The limiting groove 22 is used for the roller 31 to roll in. The limiting groove 22 is adapted to the roller 31. When the roller 31 is located in the limiting groove 22, the ventilation unit 6 is moved into place. The cooperation between the roller 31 and the limiting groove 22 facilitates the rapid positioning of the ventilation unit 6 and improves the construction efficiency. A first connecting hole 23 is provided on the side wall of the slide rail 2, and a second connecting hole 323 is provided on the side plate 322. The first connecting hole 23 and the second connecting hole 323 are connected to the same locking bolt 324. A fixing ear 325 is fixedly connected to one end of the locking bolt 324. The first connecting hole 23 and the second connecting hole 323 are both provided with a fixing hole 231 for the fixing ear 325 to pass through. During installation, pass one end of the locking bolt 324 with the fixing ear 325 through the first connecting hole 23 and the second connecting hole 323, then rotate the locking bolt 324 90 degrees so that the fixing ear 325 abuts against the side wall of the side plate 322, and then screw the locking nut 326 on the locking bolt 324 to complete the fixation of the side plate 322 and the slide rail 2.

[0031] Specifically, the second shock absorbing assembly 4 is provided with at least two groups, and is arranged in an array along the length direction of the slide rail 2, and in this embodiment, there are two groups. The second shock absorbing assembly 4 includes a fixed plate 41, a tension rope 42 and a pressure plate 46. The fixed plate 41 is fixedly connected to the ground of the installation hole 7 by anchor bolts. The pressure plate 46 is arranged above the ventilation unit 6 and abuts against the top surface of the ventilation unit 6. A pull rod 43 is inserted into the pressure plate 46. One end of the tension rope 42 is fixedly connected to the fixed plate 41, and the other end is fixedly connected to the pull rod 43. The pull rod 43 is connected to the pressure plate 46 through a limiter. The fixed plate 41, the tension rope 42 and the pull rod 43 are each provided with two groups, and are located at both ends of the pressure plate 46. The tension rope 42 can be a steel wire rope or a nylon rope, and at least two tension ropes 42 are arranged between each pull rod 43 and the fixed plate 41.

[0032] More specifically, the stopper includes a spiral plate 44 and a compression spring 45. The spiral plate 44 is threadedly connected to the pull rod 43. The compression spring 45 is sleeved on the pull rod 43. One end of the compression spring 45 abuts against the pressure plate 46, and the other end abuts against the spiral plate 44. Through the cooperation of the compression spring 45, the pressure plate 46 and the tension rope 42, while the ventilation unit 6 is fixed, the compression spring 45 is used to buffer the ventilation unit 6, and the tension rope 42 is used to absorb the vibration, further improving the shock absorption and buffering performance. The spiral plate 44 can adjust the degree of compression of the pressure plate 46 on the ventilation unit 6, so that the tension rope 42 can be tightened during regular inspections by the staff.

[0033] The slide rail 2 is detachably connected to an external guide rail 5 , and one end of the external guide rail 5 away from the slide rail 2 extends out of the mounting hole 7 .

[0034] Specifically, a first connection block 51 is integrally formed on the external guide rail 5, and a second connection block 24 is integrally formed on the slide rail 2. The first connection block 51 and the second connection block 24 fit each other, and the first connection block 51 and the second connection block 24 are fixedly connected by countersunk bolts 52. The portion of the external guide rail 5 outside the installation hole 7 can be supported by a scaffold to carry the ventilation unit 6. During installation, the ventilation unit 6 is hoisted onto the external guide rail 5, and then the roller 31 slides on the external guide rail 5 and slides onto the guide rail, which solves the problem that the ventilation unit 6 is difficult to move into the installation hole 7 in the traditional installation scheme.

[0035] Working principle: The bottom of the ventilation unit 6 is damped by the first damping component 3, and the top and the whole of the ventilation unit 6 are damped by the second damping component 4. The first damping component 3 cooperates with the second damping component 4 to improve the buffering performance of the ventilation unit 6 and reduce the possibility of vibration transmission to the subway entrance. At the same time, the slide rail 2 can facilitate the rapid positioning and movement of the ventilation unit 6, thereby improving the installation efficiency.

[0036] By setting the roller 31, rubber ring 311, sleeve 32, limit groove 22 and shock-absorbing pad 33, the rubber ring 311 and the shock-absorbing pad 33 cooperate, so that there is no hard connection between the ventilation unit 6 and the ground of the installation hole 7, thereby improving the buffering performance. At the same time, the roller 31 facilitates the movement of the ventilation unit 6 in a small space, and the limit groove 22 can limit the roller 31, and at the same time realize the positioning and fixation of the ventilation unit 6, thereby improving the installation efficiency, ensuring the reliability of the installation, and also improving the shock-absorbing ability.

[0037] By setting the external guide rail 5, the ventilation unit 6 can be directly hoisted onto the external guide rail 5 and then slid along the external guide rail 5 into the installation hole 7, thereby overcoming the problem that the ventilation unit 6 is difficult to move in the narrow installation hole 7, improving installation efficiency and reducing construction difficulty.

[0038] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
