[0041] See also Figure 1-Figure 3The present invention provides a tunnel dust removal device, comprising: a shell 1, wherein a blowing module 2 and a dust suction module 3 are arranged inside the shell 1, and the dust suction module 3 is connected to a dust removal component; the blowing modules 2 are arranged on both sides of the dust suction module 3 to form wind screens on both sides of the dust suction module 3, and the dust suction module 3 is used to suck the air containing dust between the blowing modules 2 and filter it through the dust removal component; the shell 1 is installed on a walking device, and the walking device can drive the shell 1 to move in the tunnel.

[0042] The tunnel dust removal device in the present invention is mainly used to collect dust in the tunnel. The dust on the tunnel floor is first blown up by the blowing module 2, and then the dust-containing air is sucked out by the dust suction module 3. The dust is filtered and intercepted by the dust removal component connected to the dust suction module 3, so that the dust is collected.

[0043] By arranging the blowing module 2 on both sides of the dust collection module 3, the blowing module 2 can, on the one hand, lift up the dust on the ground, which is conducive to subsequent effective capture; on the other hand, it can form a wind screen on both sides of the dust collection module 3, effectively forming an isolated space equivalent to the outside of the wind screen, and enabling the dust collection module 3 to suck the dust-containing air in the isolated space.

[0044] The blowing module 2 and the dust collection module 3 can effectively create air disturbance in the tunnel, which drives the dust in the tunnel to be lifted and sucked and filtered through the air disturbance. Combined with the isolation space between the wind screens, the irregular diffusion of dust is effectively avoided, greatly improving the dust capture effect.

[0045] The housing 1 in the present invention is installed on a traveling device, and the traveling device drives the housing 1 to move in the tunnel, which can effectively form a dynamic dust removal effect, thereby facilitating the thorough removal of dust in the tunnel.

[0046] In order to increase the volume capacity of the isolation space between the wind screens and improve the amount of air sucked in the isolation space, the shell 1 in this embodiment specifically includes two separate settings, and a group of blowing modules 2 and a group of dust collection modules 3 are respectively provided in each shell 1. At the same time, the blowing module 2 is arranged at the end of each shell 1, and the two shells 1 are mirror-symmetrical in the direction of travel, that is, the two shells 1 together constitute the setting form of two groups of blowing modules 2 and two groups of dust collection modules 3. Through this setting method, the two groups of blowing modules 2 can be arranged on both sides of the two groups of dust collection modules 3, so that the two groups of blowing modules 2 form two wind screens when blowing outward at the same time, and at the same time, the disturbance of the air between the wind screens by the dust collection module 3 during operation is enhanced, thereby effectively improving the amount of dust captured in the isolation space.

[0047] Combine Figure 4In this embodiment, each group of blowing modules 2 includes a blower 21 installed inside the shell 1. The blower 21 blows outward to blow away dust on the tunnel floor and form a wind screen. A plurality of blowing ports are provided on the shell 1. The air outlet of the blower 21 is specifically connected to the blowing port, and is used to guide the wind output by the blower 21 from the blowing port. The blowing port and the blower 21 both include multiple, and the blower 21 and the blowing port are specifically in a one-to-one correspondence, which can ensure the output effect of the wind force. At the same time, through the cooperation between multiple blowers 21 and multiple blowing ports, a stable wind screen can be formed.

[0048] Specifically, the air blowing outlet includes a top air blowing outlet 22 arranged at the top of the shell 1, and a side air blowing outlet arranged at the side of the shell 1, wherein the side air blowing outlet is arranged on both sides of the shell 1, including a first side air blowing outlet 23 and a second side air blowing outlet 24 respectively arranged on each side, and a wind plate 25 is hingedly connected to the shell parts located at the first side air blowing outlet 23 and the second side air blowing outlet 24. By controlling the movable angle of the wind plate 25, the two side air blowing outlets can output wind at different angles.

[0049] The wind plate 25 on the first side air blowing port 23 is hingedly connected to the side of the first side air blowing port 23, so that the air blowing port can output horizontally sweeping blowing wind. The wind plate 25 on the second side air blowing port 24 is hingedly connected to the top of the second side air blowing port 24, so that the air blowing port can output up and down sweeping blowing wind. The wind plates 25 are connected to push rods that can move back and forth. By connecting the push rods to driving components such as hydraulic cylinders, the wind plates 25 are driven to swing sideways within a certain angle range, so that the blowing wind output by the two air blowing ports can fully cover the sides of the shell 1.

[0050] In this embodiment, the second side air outlet 24 is disposed below the first side air outlet 23. By outputting downwardly inclined wind, it ensures that dust on the ground is effectively blown away. At the same time, the first side air outlet 23 and the second side air outlet 24 cooperate with each other to form a wind screen on the side of the housing 1.

[0051] The top air blowing port 22 does not involve blowing dust on the ground. Its main function is to cooperate with the side air blowing ports to form wind screens on both sides of the dust collection module 3.

[0052] Combine Figure 5 The dust collection module 3 includes a plurality of induced draft fans 31 installed inside the shell 1, and a plurality of air suction ports 32 opened on the side wall of the shell 1. The induced draft fans 31 and the air suction ports 32 are also in a one-to-one correspondence, and each air suction port 32 is connected to the air inlet of each induced draft fan 31.

[0053] The induced draft fan 31 in this embodiment is specifically in the form of an axial flow fan, which is a straight-cylinder shellless fan. When installing inside the shell 1, only the direction of the axial flow fan's air inlet needs to be considered. The air outlet can discharge air in any direction inside the shell 1 according to actual needs, which improves flexibility. In addition, the axial flow fan is relatively small in size, which reduces the space occupied inside the shell and facilitates the arrangement of equipment. The air outlet of the axial flow fan is openly arranged inside the shell 1, and can directly discharge the clean air filtered through the air inlet into the inside of the shell 1, forming a positive pressure inside the shell 1, and discharge the shell 1 into the tunnel through the overflow port 11 opened at the top and bottom of the shell 1. While exhausting the air, the clean air also plays a role in disturbing the air, which can blow the dust directly below and above the shell 1 to both sides of the shell 1. Combined with the air inlet 32 arranged on both sides of the shell 1, the dust capture effect is enhanced.

[0054] The suction ports 32 are evenly spaced on the sidewalls of the housing 1, increasing the combined suction area of the multiple suction ports 32 while also creating a more uniform suction force and reducing the escape of dust after blowing. Correspondingly, multiple axial fans are arranged in an array within the housing 1. In this embodiment, each housing 1 is equipped with 20 axial fans and 20 opposing suction ports 32, for a total of 40 axial fans and 40 opposing suction ports 32 across the two housings 1, ensuring a highly effective suction effect.

[0055] The outside of the air intake 32 is provided with an air inlet hood 33 connected to the shell 1. Each air inlet hood 33 is inclined outward and downward, and the outer end face of the air inlet hood 33 constitutes the air inlet surface of the air inlet hood 33. The dust removal component is installed in the air inlet hood 33. Specifically, the dust removal component includes a dust removal filter 34 installed inside the air inlet hood 33. The dust mixed in the air can be filtered and removed through the dust removal filter 34. After the dust is intercepted in the dust removal filter 34, the clean air is discharged into the interior of the shell 1 under the suction action of the axial flow fan.

[0056] The dust filter 34 in this embodiment is a wavy multi-layer metal wire filter with a certain thickness. The aperture of the outermost filter is the largest, and the inner multi-layer stacked filters intercept dust so that the dust is adsorbed on the inner multi-layer filter.

[0057] To ensure the permeability of the dust filter 34, a wind speed sensor and a vibration motor are installed on the inner side of the housing 1 of each air intake 32. The wind speed sensor and the vibration motor are both electrically connected to the control module. The wind speed sensor is used to monitor the wind speed after passing through the dust filter 34 in real time and transmit the wind speed signal to the control module. After receiving the wind speed signal, the control module determines whether to clean the dust. A wind speed threshold is set in the control module. When the wind speed is less than the threshold, the control module controls the vibration motor to start. The vibration motor drives the dust filter 34 to vibrate, so that the dust adsorbed on the dust filter 34 is detached, thereby achieving the purpose of cleaning.

[0058] A dust collecting assembly (not shown in the figure) is also provided inside the shell 1. The dust collecting assembly specifically includes a dust collecting bag arranged at the lower part of the air suction port 32 in the shell 1. During vibration cleaning, dust can fall from top to bottom into the dust collecting bag, avoiding secondary pollution inside the shell 1.

[0059] The shell 1 of the tunnel dust removal device in the present invention is in the form of a container, and the traveling device includes a railway flatbed transport vehicle for installing the container and capable of moving on the rails in the tunnel. Specifically, the railway flatbed transport vehicle includes a first railway flatbed transport vehicle and a second railway flatbed transport vehicle, and two mirror-symmetrical containers are respectively installed on the first railway flatbed transport vehicle and the second railway flatbed transport vehicle. Through this arrangement, the capacity of the isolation space between the wind screens can be increased, and the transport vehicle can suck and remove the dust between the two transport vehicles during the movement, which can be more conducive to the disturbance of air in the gap between the transport vehicles and improve the dust removal effect.

[0060] In order to ensure the normal operation of tunnel dust removal, operation modules and power modules are distributed on the first railway flatbed transport vehicle and the second railway flatbed transport vehicle. The operation modules and power modules are also in the form of containers. The operation module is provided with an operation platform and living space, and provides necessary living equipment. The power module is mainly provided with a generator set, which supplies power to the two dust removal function containers in a one-to-two power module form to ensure the reliable operation of the tunnel dust removal device.

[0061] The present invention realizes modular operation through the form of the container shell 1, and combined with the railway flatbed transport vehicle, it can realize continuous operation during the movement in the tunnel, effectively improving the dust removal efficiency.

[0062] The present invention also provides a tunnel dust removal method according to the above tunnel dust removal device, which mainly includes the following steps:

[0063] The first and second railway flatbed transport vehicles are pulled by the locomotive head, so that the railway flatbed transport vehicles drive the container-type housing 1 into the tunnel, and at the same time, functional modules such as the blowing module 2 and the dust collection module 3 are turned on;

[0064] The dust in the tunnel is blown up by the blower 21 and the blowing port in the blowing module 2, and at the same time forms a wind screen at the front and rear ends of the two railway flatbed transport vehicles;

[0065] The axial flow fan in the dust collection module 3 sucks the dust-laden air between the two wind screens and intercepts the dust on the dust removal filter 34. The clean air after dust removal is discharged through the overflow vents 11 at the top and bottom of the container. The exhaust air enhances the disturbance of the air between the wind screens and performs circulating filtration.

[0066] The functional module performs dust removal operations on the tunnel space while moving inside the tunnel. When the locomotive pulls the railway flatbed transport vehicle out of the tunnel, the dust removal of the tunnel is completed.

[0067] The tunnel dust removal method of the present invention enables the tunnel dust removal device to dynamically blow, suck and filter the dust in the tunnel during travel, thereby ensuring the dust removal effect through dynamic air disturbance.

[0068] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0069] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
