DETAILED DESCRIPTION

[0026] In order to better understand the present invention, the present invention is described in detail below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a smoke degradation device for tunnel construction includes a movable base 1 and a fan-shaped frame 4 installed on the movable base 1, the fan-shaped frame 4 is provided with a plurality of slide grooves 501 radiating outward, each of the slide grooves 501 is provided with a transmission block 502 that can slide along the slide groove 501, the movable base 1 on one side of the fan-shaped frame 4 is provided with a spray assembly, and the movable base 1 on the other side of the fan-shaped frame 4 is provided with an adjustment assembly, the transmission block 502 is connected to the nozzle 202 in the spray assembly and is also connected to the connecting rod 602 in the adjusting assembly, so that the position of the transmission block 502 in the slide groove 501 is adjusted by the connecting rod 602, thereby adjusting the position of the nozzle 202.

[0029] like Figure 1 and Figure 3As shown, the spray assembly includes a water pump 302, a water distributor 303, and a plurality of the nozzles 202. The water distributor 303 is connected to the water outlet of the water pump 302 through a pipeline, and each nozzle 202 is connected to the water distributor 303 through a hose 304. A water storage tank 301 is arranged below the movable base 1, and the water inlet end of the water pump 302 is connected to the interior of the water storage tank 301. Through the operation of the water pump 302, the liquid in the water storage tank 301 is sent into the water distributor 303, and then the liquid enters each nozzle 202 through each hose 304. Finally, the liquid is sprayed outward through the nozzle 202 to spray the smoke and dust in the tunnel, so that the smoke and dust are lowered and eliminated.

[0030] The spray head 202 is connected to the transmission block 502 via a connector 201. The connector 201 may be a snap-fitting piece, a clamping piece, or other components in the prior art, as long as the spray head 202 can be fixed to the transmission block 502. When a snap-fitting piece or a clamping piece is used, the spray head 202 can be easily removed, so that it is convenient to replace and repair the spray head when it is damaged or blocked.

[0031] like Figure 2 and Figure 4 As shown, the adjustment assembly includes a support member 701, a threaded rod 703, a threaded sleeve 702, a mounting plate 601 and a plurality of connecting rods 602, the support member 701 is fixedly arranged on the movable base 1, one end of the threaded rod 703 is rotatably connected to the fan-shaped frame 4, and the other end is rotatably connected to the support member 701, the mounting plate 601 is fixedly sleeved on the outside of the threaded sleeve 702, the threaded sleeve 702 is threadedly sleeved on the threaded rod 703, one end of each connecting rod 602 is rotatably connected to the mounting plate 601, and the other end is rotatably connected to one of the transmission blocks 502.

[0032] The adjustment assembly further includes an adjustment handle 704, and the adjustment handle 704 is fixedly connected to the threaded rod 703. Preferably, in this embodiment, one end of the threaded rod 703 connected to the support member 701 passes through the support member 701 and is fixedly connected to the adjustment handle 704.

[0033] The number of the slide slots 501 is not less than the number of the transmission blocks 502, and the number of the transmission blocks 502 is not less than the number of the connecting rods 602. In this embodiment, preferably, the number of the slide slots 501, the transmission blocks 502 and the connecting rods 602 is the same.

[0034] The sliding groove 501 is generally located above the position where the threaded rod 703 is connected to the fan-shaped frame 4 , and the connecting rod 602 is generally located above the threaded rod 703 .

[0035] like Figure 4 As shown, the adjustment assembly also includes a guide plate 801 and at least one guide rod 802. The guide plate 801 is fixedly connected to the mounting plate 601. Both ends of the guide rod 802 are respectively fixedly connected to the fan-shaped frame 4 and the support member 701. The guide plate 801 is slidably connected to the guide rod 802.

[0036] In this embodiment, it is preferred that the guide plate 801 is disposed at the lower part of the mounting plate 601, the guide rod 802 is disposed below the threaded rod 703, two guide rods 802 are disposed, the guide plate 801 is provided with through holes corresponding to the two guide rods 802, and the two guide rods 802 respectively pass through the two through holes on the guide plate 801. It should be noted that the manner of achieving sliding connection between the guide rod 802 and the guide plate 801 is not limited to the manner described above, and can also be achieved by any other manner disclosed in the prior art, such as providing a slider or notch matching the guide rod 802 on the guide plate 801.

[0037] The slide groove 501 is at least one of a cross-shaped slide groove, a T-shaped slide groove, a trapezoidal slide groove, and an L-shaped slide groove, and the shape of the transmission block 502 matches the shape of the slide groove 501 in which it is located.

[0038] Universal wheels are arranged below the movable base 1 .

[0039] When using the tunnel construction smoke degradation equipment, first move the equipment to the designated position, and then drive the threaded rod 703 to rotate through the adjustment handle 704. During the rotation of the threaded rod 703, the threaded sleeve 702 moves forward and backward on the threaded rod 703, thereby driving the mounting plate 601 to approach or move away from the fan-shaped frame, and further driving the transmission block 502 to move up and down in the slide groove 501 through the connecting rod 602. The up and down movement of the transmission block 502 drives the nozzle 202 to gather or disperse, thereby adjusting the position of the nozzle 202. After the position of the nozzle 202 is adjusted, the water pump 302 is controlled to operate, and the liquid in the water storage tank 301 is transported to each nozzle 202, and each nozzle 202 sprays liquid to perform a spray degradation operation on the smoke in the tunnel.

[0040] By adjusting the position of the nozzle 202, the tunnel construction smoke degradation equipment can be adapted to tunnels of different cross-sectional sizes. Obviously, the more dispersed the nozzle 202 is, the larger the spray range is, and the more suitable it is for smoke degradation operations in tunnels with larger cross-sectional sizes. The more concentrated the nozzle 202 is, the smaller the spray range is, and the more suitable it is for smoke degradation operations in tunnels with smaller cross-sectional sizes. Through the adjustment component, the positions of all the nozzles 202 can be adjusted at the same time, and the adjustment efficiency is higher.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the above embodiments describe the present invention in detail, those skilled in the art should understand that they may modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents, and these replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present invention.
