Technical Field

[0001] The present invention belongs to the technical field of dust removal devices, and in particular relates to a dust removal device and a dust removal method for a binocular vision camera. Background Art

[0002] With the increasing intelligence of coal mines, gangue sorting is gradually shifting from manual sorting to automated gangue sorting systems. Automatic gangue identification technology, a crucial component of gangue sorting systems, primarily includes gamma ray and image recognition methods. Binocular vision cameras are the core equipment for image recognition. However, the presence of large amounts of dust during gangue sorting can easily contaminate the lens. There are two main existing methods for addressing lens contamination: 1. Regular manual cleaning. This is labor-intensive and time-consuming. 2. Installing a dust cover. While this improves the lens contamination problem over time, the dust cover still requires regular manual replacement, which does not fundamentally resolve the issue. 3. Dust absorption and obstruction in harsh working conditions significantly reduce the gangue recognition rate of binocular vision cameras. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] The dust removal device and dust removal method for a binocular vision camera according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 3 As shown, the dust removal device of the binocular vision camera according to an embodiment of the present invention includes: a camera body 1, two dust removal parts 3 and an air supply part 2, the camera body 1 has two lenses 11; the two dust removal parts 3 are installed on the corresponding lenses 11; the air supply part 2 is arranged on the camera body 1, and the air supply part 2 has an air inlet end and two air outlet ends, the air inlet end is connected to the external air source, one air outlet end is connected to one dust removal part 3, and the other air outlet end is connected to the other dust removal part 3.

[0028] The present invention provides a dust removal component 3 on each of the two lenses 11, introduces gas into the two dust removal components 3 through the air supply component 2 to perform automatic dust removal operations, blows dust away from the lenses 11, eliminates the need for manual regular cleaning, ensures the shooting effect of the binocular vision camera, and guarantees the coal gangue recognition rate.

[0029] Among them, the air supply part 2 includes: a flow regulating pump 21 and two delivery pipes 22, the flow regulating pump 21 is connected to the external air source; one end of a delivery pipe 22 is connected to the flow regulating pump 21, and the other end of a delivery pipe 22 is connected to a dust removal part 3, one end of another delivery pipe 22 is connected to the flow regulating pump 21, and the other end of another delivery pipe 22 is connected to another dust removal part 3.

[0030] In other words, the flow regulating pump 21 has an inlet and two outlets. The inlet is connected to the external gas source, and the two outlets are respectively connected to two delivery pipes 22. The two delivery pipes 22 are respectively connected to two dust removal parts 3. The flow regulating pump 21 mainly adjusts the flow rate of the incoming gas. In this embodiment, the delivery pipe 22 is L-shaped.

[0031] The dust removal member 3 includes a receiving tube 31 and an air guide unit 32. One end of the receiving tube 31 is connected to the delivery tube 22, and the other end of the receiving tube 31 is connected to the air guide unit 32. In this embodiment, the receiving tube 31 is L-shaped and primarily connects to the delivery tube 22, while the air guide unit 32 primarily directs air in front of the lens 11.

[0032] On this basis, the air guide unit 32 includes a light-transmitting sheet 322, which is installed on the lens 11. The light-transmitting sheet 322 is provided with an annular groove 3222 and an air inlet 3221. One end of the air inlet 3221 is connected to the other end of the receiving tube 31, and the other end of the air inlet 3221 is connected to the annular groove 3222.

[0033] The light-transmitting sheet 322 needs to remain transparent so as not to cause any obstruction to the shooting of the lens 11. At the same time, the light-transmitting sheet 322 protects the lens 11 to prevent dust from falling on the lens 11. The air inlet 3221 introduces gas into the annular groove 3222, thereby forming an annular air outlet, blowing air in the circumferential direction to improve the dust removal effect.

[0034] Preferably, a sealing ring 321 is provided between the light-transmitting sheet 322 and the lens 11 . The sealing ring 321 is annular and can prevent dust from entering between the light-transmitting sheet 322 and the lens 11 .

[0035] Preferably, a ring 323 is provided on the side of the light-transmitting sheet 322 away from the lens 11. The ring 323 is annular and protects the light-transmitting sheet 322 by preventing collisions with the light-transmitting sheet 322. At the same time, the ring 323 can limit and guide the gas.

[0036] The center of the circle corresponding to the light-transmitting sheet 322, the center of the circle corresponding to the retaining ring 323, and the center of the circle corresponding to the annular groove 3222 all fall on the center line of the lens 11. This design can avoid obstruction of the lens 11 in shooting.

[0037] On this basis, the annular groove 3222 is opened on the side of the light-transmitting sheet 322 away from the lens 11, and the retaining ring 323 is located at the opening of the annular groove 3222. The outer diameter of the retaining ring 323 is larger than the outer diameter of the annular groove 3222, and the inner diameter of the retaining ring 323 is smaller than the outer diameter of the annular groove 3222 and larger than the inner diameter of the annular groove 3222.

[0038] In other words, the gas passes through the delivery tube 22, the receiving tube 31, the air inlet 3221, and finally enters the annular groove 3222. The gas is blown away from the lens 11. The dust generated by the movement of the gangue is blown away by the gas and prevented from landing on the light-transmitting sheet 322. At the same time, because the retaining ring 323 blocks the gas blown out of the annular groove 3222, some of the gas is blown toward the center of the light-transmitting sheet 322, further improving the dust removal effect. During use, the flow regulating pump 21 adjusts the amount of gas according to the amount of dust generated by the gangue, achieving adaptive dust removal.

[0039] The present invention also discloses a dust removal method, which uses the dust removal device of the above-mentioned binocular vision camera to remove dust, including the following steps: step 1: an external air source continuously supplies air to the air supply component 2; step 2: the dust concentration of the environment where the binocular vision camera is located is monitored in real time through a dust sensor; step 3: the flow regulating pump 21 adjusts the gas flow in real time according to the dust concentration, and the dust concentration is positively correlated with the gas flow.

[0040] It should be noted that during the dust removal process of the present application, when the dust concentration is zero, the gas flow output by the flow regulating pump 21 is not zero. That is to say, even when the dust concentration is very low, the dust removal device is still performing air blowing and dust removal work, which can avoid dust falling in front of the lens 11 to the greatest extent.

[0041] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
