[0022] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0023] This embodiment provides a dust removal device for a mobile platform, and its overall structure is as follows: Figure 1 and 2 As shown, it mainly includes an air inlet flange 1, an air inlet screen 2, a dust removal device cavity 3, an upper shell 4, a cyclone dust removal tube module 5, a lower shell 6, an air outlet screen 7, an air outlet flange 8, a dust removal fan mounting flange 9, a dust removal fan mounting bracket 10, a dust removal fan 11 and a controller 12.

[0024] The air inlet screen 2 and the air outlet screen 7 are respectively fixedly connected to the air inlet flange 1 and the air outlet flange 8 by bolts. The air inlet flange 1 and the air outlet flange 8 with the air inlet screen 2 and the air outlet screen 7 are respectively fixedly connected to the air inlet and the air outlet of the dust removal device cavity 3 by bolts.

[0025] The upper shell 4 and the lower shell 6 are respectively fixedly connected to the inside of the dust removal device cavity 3, and the cyclone dust removal tube module 5 is riveted and fixed between the upper shell 4 and the lower shell 6 in a horizontal installation manner.

[0026] The dust removal fan mounting flange 9 and the controller 12 are installed on the outer wall of the dust removal device cavity 3, the dust removal fan bracket 10 is fixedly connected to the dust removal fan mounting flange 9 by bolts, the dust removal fan 11 is fixedly connected to the dust removal fan bracket 10 by bolts, the dust extraction port of the dust removal fan 11 is connected to the interior of the dust removal device cavity 3, and the dust extraction work of the dust removal fan 11 is controlled by the controller 12.

[0027] like Figure 3 As shown, the cyclone dust collection tube module 5 includes a plurality of cyclone dust collection units evenly distributed horizontally, and each cyclone dust collection unit includes a cyclone dust collection tube body 13, a fixed spiral blade 14 and a dust separation port 15. Among them, the top air inlet of the cyclone dust collection tube body 13 is fixedly connected to the air inlet of the upper shell 4, the bottom air outlet of the dust separation port 15 is fixedly connected to the air outlet of the lower shell 6, the bottom air outlet of the cyclone dust collection tube body 13 is sleeved on the top air inlet of the dust separation port 15, and a dust exhaust channel is formed between the cyclone dust collection tube body 13 and the dust separation port 15. A fixed spiral blade 14 is installed inside the cyclone dust collection tube body 13.

[0028] The working principle of the dust removal device for the mobile platform of the present invention is:

[0029] The air inlet flange 1 of the dust removal device is connected to the air inlet of the mobile platform three-defense system by bolts, and the air outlet flange 8 is connected to the remaining equipment of the mobile platform three-defense system along the air outlet direction.

[0030] When the dust removal device is turned on, the controller 12 receives the superior command and transmits the information to the dust removal fan 11. The dust-containing airflow passes through the air intake screen 2 along the air intake direction. The air intake screen 2 filters out larger particles and impurities in the dust-containing airflow, and adjusts the speed and direction of the airflow so that the airflow enters the cyclone dust removal tube module 5 evenly. After the airflow enters the cyclone dust removal tube body 13 from the tangential direction, under the action of the fixed spiral blades 14, the dust-containing airflow changes from linear motion to circular motion, forming an external vortex. During the rotation of the dust-containing airflow, due to the effect of inertia, the dust particles are affected by the centrifugal force and gradually move toward the tube wall. The dust particles that reach the tube wall move downward along the tube wall under the combined action of the airflow and gravity, and are finally intercepted by the lower shell 6 through the outer side of the dust separation port 15, realizing the preliminary separation of dust and gas. The clean air is further filtered through the air outlet screen 7 to remove the remaining tiny particles, and the speed and direction of the air outlet airflow are adjusted to ensure the normal operation of subsequent equipment.

[0031] The motor of the dust removal fan 11 drives the fan blades to rotate at high speed, generating a strong airflow to form a negative pressure environment, so that the dust particles intercepted by the lower shell 6 can be effectively sucked into the dust removal fan 11 in real time, and finally discharged from the dust removal device through the dust exhaust port of the dust removal fan 11. The length of the dust exhaust pipe can be adapted according to the motorized platform and fixed at the dust exhaust port and the dust outlet of the motorized platform with a clamp.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
