Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust devices, and in particular to a smoke exhaust device for underground garages. Background Technology

[0002] Underground parking garages are enclosed spaces where vehicles generate exhaust fumes, including harmful gases such as carbon monoxide and nitrogen oxides, when parked and in motion. These gases are difficult to disperse naturally. Smoke extraction systems can effectively remove these harmful gases, refresh the air in the garage, and maintain air quality. In the event of a fire, smoke extraction systems can quickly remove smoke lingering in the garage, effectively curbing the spread of smoke and ensuring the smooth progress of personnel evacuation and rescue operations.

[0003] In existing technologies, the location and number of smoke inlets of smoke exhaust devices are mostly fixed, which is not convenient to adjust as needed. Therefore, we propose a smoke exhaust device for underground parking garages to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the number and location of the smoke inlets of most smoke exhaust devices are relatively fixed and not easy to adjust as needed, and to propose a smoke exhaust device for underground garages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smoke extraction device for an underground parking garage includes:

[0007] Hollow exhaust seat;

[0008] Multiple smoke inlets are located at the bottom of the hollow exhaust base;

[0009] The smoke extraction mechanism is located on one side of the hollow exhaust seat and is used to extract the gas inside the hollow exhaust seat.

[0010] Mounting plate, located on one side of the hollow exhaust base;

[0011] Multiple baffles are slidably installed on one side of the mounting plate to open multiple smoke inlets;

[0012] A moving mechanism, mounted on a mounting plate, is used to move multiple baffles;

[0013] A connecting plate is fixedly installed on the top of the mounting plate. One side of the connecting plate contacts one side of the hollow exhaust seat, and a rectangular hole is provided on the connecting plate.

[0014] A rectangular plate is fixedly installed on one side of the hollow exhaust base, with a rectangular hole running through one side of the rectangular plate;

[0015] A limiting mechanism, located on a rectangular plate, is used to limit the other side of the connecting plate.

[0016] Preferably, the smoke extraction mechanism includes a connecting box fixedly connected to one side of the hollow exhaust seat, a smoke extraction fan fixedly installed on one side of the connecting box, the air inlet of the smoke extraction fan being connected to the inside of the connecting box, and a conveying pipe fixedly connected to the air outlet of the smoke extraction fan, the conveying pipe being used to connect to the smoke exhaust channel of the underground garage.

[0017] Preferably, the moving mechanism includes multiple moving blocks, one side of which is fixedly connected to multiple baffles.

[0018] Preferably, one side of the mounting plate has multiple movable slots, and multiple movable blocks are slidably installed in the multiple movable slots respectively.

[0019] Preferably, each of the multiple movable slots is rotatably installed with a screw, and the multiple screws are threadedly connected to the multiple movable blocks respectively.

[0020] Preferably, multiple motors are fixedly mounted on one side of the mounting plate, and the output shaft of the motor is fixedly connected to one end of the corresponding screw.

[0021] Preferably, the limiting mechanism includes a limiting plate, one side of which contacts the side of the connecting plate away from the hollow exhaust seat.

[0022] Preferably, the top of the rectangular plate is provided with a reset groove, the limiting plate is slidably installed in the reset groove, and one end of a plurality of springs is fixedly installed at the bottom of the limiting plate, and the other end of the plurality of springs is fixedly connected to the bottom inner wall of the reset groove.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] This design involves pressing down on the limiting plate, which compresses multiple springs. The connecting plate, through a rectangular hole, can then be fitted onto the rectangular plate. At this point, the rectangular plate passes through the rectangular hole, and one side of the connecting plate contacts the hollow exhaust seat. Releasing the limiting plate releases the springs, causing the limiting plate to move upwards. The limiting plate then restricts the other side of the connecting plate, connecting and fixing it to the hollow exhaust seat. Multiple baffles then contact the bottom of the hollow exhaust seat. The multiple smoke inlets allow selection of the desired smoke inlets; unused inlets are closed by baffles. The closing process is as follows: a motor drives a screw to rotate, causing the rectangular block to move the corresponding baffle, closing the unused smoke inlets.

[0025] This invention is easy to assemble and allows for the selection of different smoke inlet positions to meet various usage requirements. Attached Figure Description

[0038] A moving mechanism, mounted on the mounting plate 6, is used to move multiple baffles 7;

[0039] The connecting plate 12 is fixedly installed on the top of the mounting plate 6. One side of the connecting plate 12 contacts one side of the hollow exhaust seat 1. A rectangular hole 13 is provided on the connecting plate 12.

[0040] A rectangular plate 14 is fixedly installed on one side of the hollow exhaust seat 1, and a rectangular hole 13 passes through one side of the rectangular plate 14.

[0041] A limiting mechanism, located on the rectangular plate 14, is used to limit the other side of the connecting plate 12.

[0042] In this embodiment, the smoke extraction mechanism includes a connecting box 3 fixedly connected to one side of the hollow exhaust seat 1. A smoke extraction fan 4 is fixedly installed on one side of the connecting box 3. The air inlet of the smoke extraction fan 4 is connected to the inside of the connecting box 3. The air outlet of the smoke extraction fan 4 is fixedly connected to a conveying pipe 5. The conveying pipe 5 is used to connect to the smoke exhaust channel of the underground garage.

[0043] In this embodiment, the moving mechanism includes multiple moving blocks 9, and one side of each of the multiple moving blocks 9 is fixedly connected to multiple baffles 7.

[0044] In this embodiment, a plurality of movable slots 8 are provided on one side of the mounting plate 6, and a plurality of movable blocks 9 are slidably installed in the plurality of movable slots 8.

[0045] In this embodiment, screws 10 are rotatably installed in multiple movable slots 8, and the multiple screws 10 are threadedly connected to multiple movable blocks 9 respectively.

[0046] In this embodiment, a plurality of motors 11 are fixedly installed on one side of the mounting plate 6, and the output shaft of the motor 11 is fixedly connected to one end of the corresponding screw 10.

[0047] In this embodiment, the limiting mechanism includes a limiting plate 16, one side of which contacts the side of the connecting plate 12 away from the hollow exhaust seat 1.

[0048] In this embodiment, a reset groove 15 is provided on the top of the rectangular plate 14, and a limiting plate 16 is slidably installed in the reset groove 15.
