Description

Technical Field

[0001] This utility model relates to the technical field of blower-type camera cleaning tools, and in particular to a blower-type cleaning device for pressure cleaning of underground coal mine cameras. Background Technology

[0002] In the process of underground coal mining operations, multiple cameras are usually installed to achieve real-time monitoring of the underground working environment, equipment operation status and personnel safety. However, the underground environment of coal mines is harsh, with a large amount of coal dust, rock dust and other dust particles in the air. These dust particles are very easy to adhere to the lens surface of the camera. As the dust accumulates, it will seriously obstruct the camera's field of view, resulting in a blurry monitoring image that cannot accurately reflect the actual situation underground. This will affect the normal operation of the monitoring system and bring great hidden dangers to the safe production of coal mines. Traditional camera cleaning methods often fail to meet practical needs. Some cleaning devices are not precise enough in controlling airflow, making it impossible to accurately clean different levels of dust coverage, resulting in poor cleaning effects. Some devices also lack effective backflow prevention measures, which can easily lead to gas or dust backflow during use, contaminating the inside of the device, affecting its lifespan and cleaning effect. Moreover, after the shut-off valve is closed, there is no reliable sealing measure, allowing dust to easily enter the device and damage internal components. Therefore, these problems need to be improved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 5 This utility model discloses a blower-type cleaning device for cleaning underground coal mine cameras, comprising a first sealed box 1 for easy installation of an air pump 10; a second sealed box 2 is located at the rear end of the first sealed box 1 for easy installation of an anti-backflow mechanism; a hose 3 is connected to the rear end of the second sealed box 2 for easy connection of a shut-off valve 4; the other end of the hose 3 is connected to the shut-off valve 4 via a flange, which allows control of the gas content that the air pump 10 can extract, thereby controlling the impact force during blower cleaning of the camera; mounting plates are installed on one side of both the first sealed box 1 and the second sealed box 2, and an anti-backflow mechanism is installed inside the second sealed box 2; a mounting rod is installed on the upper end of the shut-off valve 4, and a valve wheel 5 is located at the center of the mounting rod. The valve wheel 5 facilitates manual control of the size of the internal groove of the shut-off valve 4; the other end of the valve wheel 5 is located inside the shut-off valve 4, and a position sensor 6 is installed on the mounting rod. The position sensor 6 facilitates sensing the height of the lead screw, thereby determining whether the shut-off valve 4 is closed; the anti-backflow mechanism includes a support rod 7 fixed inside the second sealing box 2, which facilitates the installation of the spring 8 and the rubber pad 9; the rear end of the support rod 7 is connected to the spring 8. Through the spring 8 and the rubber pad 9, air enters the second sealing box 2 through the hose 3. When there is a forward flow of gas, the gas will push the rubber pad 9 forward and compress the spring 8 to form a channel, allowing the air to pass smoothly; when the air pump 10 stops working or the airflow reverses, the spring 8 will return to its original state and push the rubber pad 9 backward; the spring 8 is connected to the rubber pad 9.

[0015] In this invention, the rubber pad 9 is frustoconical, and the diameter of the front end of the rubber pad 9 is the same as the diameter of the air inlet end of the second sealing box 2. An air pump 10 is installed inside the first sealing box 1. The air inlet end of the air pump 10 is connected to the air outlet end of the second sealing box 2 through a flange, and the air outlet end of the air pump 10 faces the front end. A sealing plate 12 is hinged to the upper part of the front end of the first sealing box 1. The sealing plate 12 can close the first sealing box 1 after the shut-off valve 4 is closed, so as to prevent dust from entering the interior of the first sealing box 1 when it is not in use. A motor 11 is installed on one side of the first sealing box 1. The rotation of the motor 11 drives the sealing plate 12 to rotate, thereby completing the sealing of the first sealing box 1. The output shaft of the motor 11 is connected to the hinge shaft of the sealing plate 12 through a coupling.

[0016] In this utility model, the position sensor 6 is a FST-RH pressure-resistant outer tube magnetostrictive displacement sensor.

[0017] Working Principle: When using the blower-type cleaning device for cleaning cameras in coal mines, the entire device must first be installed, and the circuit layout of electrical equipment such as the air pump 10, motor 11, and position sensor 6 must be completed. Then, the air pump 10 installed inside the first sealed box 1 and the shut-off valve 4 connected to the hose 3 via a flange are opened. At this time, outside air enters the air pump 10 through the shut-off valve 4. The operator can rotate the valve wheel 5 at the center of the mounting rod at the upper end of the shut-off valve 4 to adjust the size of the internal groove of the shut-off valve 4, thereby controlling the air intake. Simultaneously, the position sensor 6, a model FST-RH pressure-resistant external tube magnetostrictive displacement sensor installed on the mounting rod, monitors the position of the valve wheel 5 in real time and provides timely feedback, achieving precise control of the air intake. This allows the cleaning airflow to be flexibly adjusted according to the actual dust level on the camera surface, effectively preventing damage to the camera due to excessive impact. Air enters the second sealing box 2, which is connected to the rear end of the first sealing box 1, through the hose 3. When the gas flows forward, it pushes the rubber pad 9 connected to the spring 8 at the rear end of the internal support rod 7 of the second sealing box 2, compressing the spring 8 to form a gas channel, allowing air to pass smoothly and enter the air pump 10. When the air pump 10 stops working or the airflow reverses, the spring 8 returns to its original shape, pushing the rubber pad 9 backward. Since the rubber pad 9 is frustoconical and its front diameter is the same as the diameter of the air inlet of the second sealing box 2, it can tightly block the air inlet of the second sealing box 2, preventing gas or dust from flowing back into the device. When the cleaning function needs to be activated, the motor 11 installed on one side of the first sealing box 1 will start. Its output shaft drives the sealing plate 12 hinged to the upper front end of the first sealing box 1 to rotate through the coupling, causing the sealing plate 12 to open. At this time, the cleaning airflow generated by the air pump 10 blows out from the front outlet of the first sealing box 1, specifically cleaning the dust and other impurities on the surface of the underground coal mine camera. When the cleaning work is completed, after the operator closes the shut-off valve 4, the position sensor 6 will detect that the shut-off valve 4 is closed and transmit the signal to the motor 11. The motor 11 will then drive the sealing plate 12 to rotate and close again, preventing dust from entering the first sealing box 1 when not in use and protecting components such as the air pump 10 inside the box from dust damage. Finally, the entire device should be maintained regularly according to the usage specifications to ensure that the device can operate stably in subsequent use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
