Description

Technical Field

[0001] The invention belongs to the technical field of camera cleaning devices, and in particular relates to a wind-powered camera cleaning device in an underground coal mine. Background Art

[0002] In the underground working environment of coal mines, cameras are key safety monitoring equipment, and their operating conditions directly affect the safety monitoring effect of the mine. However, the unique humid and dusty environment of coal mines poses severe challenges to the normal operation of cameras. The humidity in the underground environment is high, and coal ash and fine particles generated during coal mining are easily attached to the surface of the camera, causing the camera lens to be covered and the image to become blurred, seriously affecting the clarity and real-time performance of the monitoring screen.

[0003] Currently, the cleaning method for camera lens contamination mainly relies on manual operation. This method is not only inefficient, but also has significant safety hazards. On the one hand, manual cleaning requires frequent entry into the mine, which greatly increases the labor intensity and safety risks of workers; on the other hand, manual operation cannot ensure the timeliness and thoroughness of cleaning, and the cleaning effect is often unsatisfactory.

[0004] In addition, most existing camera cleaning devices on the market use power as a driving source. Considering the special environment of coal mines, any new equipment or systems must meet strict explosion-proof requirements.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0050] The shapes and sizes of the components in the drawings do not reflect the actual proportions of the products, and are only intended to illustrate the contents of the present invention.

[0051] Example 1

[0052] like Figure 1-4 As shown, a wind-powered camera cleaning device for underground coal mines provided by the present invention includes a protective shell 1, a wind energy collection structure, a first kinetic energy transfer structure, an energy storage structure, a second kinetic energy transfer structure and a cleaning structure.

[0053] The protective housing 1 is used to be fixed to the bottom of the camera 2 by bonding, welding, magnetism, screwing or other common fixing methods, providing an installation basis for the entire device.

[0054] The wind energy collection structure is rotatably arranged outside the protective shell 1, and its function is to convert wind energy into rotational kinetic energy. Specifically, the structure includes a transmission shaft 4, which is rotatably matched with the side wall of the protective shell 1, and one end of the transmission shaft 4 that partially extends out of the protective shell 1 is provided with blades 5 arranged along the circumference. When the blades 5 are driven by the airflow, the transmission shaft 4 is driven to rotate.

[0055] The first kinetic energy transfer structure is arranged inside the protective housing 1, and is used to transfer the kinetic energy collected by the wind energy collection structure backward. The structure is composed of a first gear 6 fixedly arranged at one end of the transmission shaft 4 extending into the protective housing 1, and a second gear 7 rotatably arranged at one side thereof. The first gear 6 and the second gear 7 are meshed and transmitted, and the number of teeth of the first gear 6 is greater than the number of teeth of the second gear 7. The transmission and speed increase of kinetic energy are achieved through this gear transmission mode.

[0056] The energy storage structure is arranged at the rear side of the first kinetic energy transmission structure, and is used for intermittently storing and releasing the kinetic energy collected by the wind energy collection structure. It includes a spring 8 and a transmission component, and the transmission component is used for intermittent meshing transmission with the second gear 7. One end of the spring 8 is fixedly connected to the transmission component, and the other end is fixedly connected to the inner wall of the protective shell 1. When the transmission component rotates, the spring 8 is driven to contract, thereby realizing energy storage (i.e., converting kinetic energy into elastic potential energy). Among them, the transmission component includes a fixed base 9, a sliding shaft 10, a transmission gear set and an elastic reset member 11. The fixed base 9 is fixedly arranged inside the protective shell 1, the sliding shaft 10 is penetrated on the fixed base 9 and movably connected thereto, the transmission gear set is fixedly arranged on the sliding shaft 10, and the elastic reset member 11 is arranged at one end of the sliding shaft 10, one end is rotatably connected to the sliding shaft 10, and the other end is fixedly connected to the inner wall of the protective shell 1, and one end of the spring 8 is fixedly connected to the gear set, and the connection position of the other end with the protective shell 1 deviates from the set distance of the transmission gear set in the direction close to the cleaning brush 3. In this way, after the mainspring 8 contracts to a certain extent, it will pull the sliding shaft 10 to move in the direction close to the cleaning brush 3. At this time, the transmission gear set is disconnected from the second gear 7, and at the same time, the transmission gear set is connected to the second kinetic energy transfer structure to release the kinetic energy collected by the mainspring 8 during the contraction process. When the kinetic energy is released, the elastic reset member 11 drives the sliding shaft 10 to reset. At this time, the energy storage structure is disconnected from the second kinetic energy transfer structure and continues to store energy.

[0057] In this embodiment, the elastic reset member 11 is a coil spring, which is rotatably arranged at the end of the sliding shaft 10 away from the cleaning brush 3 through a bearing 21. At this time, one end of the coil spring is connected to the bearing 21, and the other end is fixedly connected to the inner wall of the protective shell 1. During the rotation of the sliding shaft 10, the coil spring will not be twisted due to the presence of the bearing 21. During the contraction of the spring 8, when the deformation force is greater than the tension of the coil spring, the sliding shaft 10 will be pulled to move away from the end of the coil spring. After the spring 8 releases the kinetic energy, the deformation force decreases. At this time, the coil spring pulls the sliding shaft 10 to slide and reset toward the end close to the coil spring.

[0058] The transmission gear set includes a first transmission gear 12 and a second transmission gear 13. The first transmission gear 12 is used for meshing and transmission with the second gear 7, and the number of teeth of the first transmission gear 12 is smaller than that of the second transmission gear 13, so as to further realize the speed increase and transmission of kinetic energy.

[0059] The second kinetic energy transfer structure is arranged on one side of the energy storage structure, and is used to intermittently release the kinetic energy stored in the energy storage structure. The structure includes an output gear 14, which is meshed with the second transmission gear 13 to transmit the kinetic energy released by the mainspring 8.

[0060] The cleaning structure includes a kinetic energy conversion unit and a cleaning brush 3. The cleaning brush 3 is arranged outside the protective housing 1 and is used to wipe the camera 2. The cleaning brush 3 is made of a soft and wear-resistant material, such as microfiber or specially treated nylon, to effectively remove dust and soot while protecting the lens surface from damage.

[0061] The kinetic energy conversion unit is used to convert the kinetic energy transmitted by the second kinetic energy transmission structure into a driving force for driving the cleaning brush 3 to reciprocate, so as to drive the cleaning brush 3 to perform a wiping action.

[0062] The kinetic energy conversion unit specifically includes an output shaft 15 , a crank 16 , a connecting rod 17 , a sliding block 18 , a slideway 19 and an output gear 14 .

[0063] The output shaft 15 is rotatably disposed in the protective housing 1 via a support base 22 , and the output gear 14 is fixedly disposed at one end of the output shaft 15 .

[0064] One end of the crank 16 is fixedly connected to the end of the output shaft 15 away from the output gear 14, and the crank 16 and the output shaft 15 form an L-shaped crank shape. One end of the connecting rod 17 is hinged to the end of the crank 16 away from the output shaft 15, and the other end is hinged to the sliding block 18. The slideway 19 is fixedly set in the protective shell 1, and the sliding block 18 is slidably matched with the slideway 19. The length extension direction of the slideway 19 is parallel to the width direction of the camera 2. Among them, the brush handle of the cleaning brush 3 is fixedly set on the sliding block 18.

[0065] In this way, the output shaft 15, crank 16, connecting rod 17, sliding block 18 and slideway 19 together constitute a crank slider structure, and the output gear 14 rotates to drive the output shaft 15 to rotate. The rotation of the output shaft 15 will be converted into the reciprocating sliding of the sliding block 18 along the slideway 19, so that the brush head of the cleaning brush 3 can wipe the camera 2 smoothly and reciprocatingly.

[0066] Furthermore, in order to ensure that the sliding degree of the sliding shaft 10 can meet the requirements during the sliding process, a stopping component is provided on the sliding shaft 10 to limit the relative sliding distance between the sliding shaft 10 and the fixed base 9 .

[0067] In this embodiment, the stopper component includes two stopper rings 20 fixedly arranged on the sliding shaft 10, and the two stopper rings 20 are arranged on both sides of the fixed base 9. In this way, when the spring 8 shrinks and deforms, it pulls the sliding shaft 10 to slide toward the end close to the cleaning brush 3. During the sliding process, the stopper ring 20 on the side of the sliding shaft 10 close to the coil spring touches the fixed base 9 to stop sliding. At this time, the second transmission gear 13 is just engaged with the output gear 14, and the first transmission gear 12 is disengaged from the second gear 7. After the spring 8 releases all kinetic energy, the coil spring pulls the sliding shaft 10 to slide away from the cleaning brush 3. During the sliding process, the stopper ring 20 on the side of the sliding shaft 10 away from the coil spring touches the fixed base 9 to stop sliding. At this time, the second transmission gear 13 is just disengaged from the output gear 14, and the first transmission gear 12 is engaged with the second gear 7.

[0068] It should be noted that, considering that the transmission structure in the device has relatively low requirements for transmission accuracy and load, all gears are made of plastic material. Plastic gears are lighter and have less inertia, which enables them to achieve smoother transmission when changing positions with the sliding shaft 10.

[0069] The working principle of the present invention is as follows:

[0070] When there is airflow in the well, the wind energy collection structure starts to work. The airflow drives the blades 5 to rotate, and the blades 5 drive the transmission shaft 4 to rotate, thereby rotating the first gear 6. Since the first gear 6 is meshed with the second gear 7, and the number of teeth of the first gear 6 is greater than the number of teeth of the second gear 7, the second gear 7 will rotate at a higher speed to achieve the increased speed transmission of kinetic energy.

[0071] As the second gear 7 rotates, when the first transmission gear 12 in the transmission component meshes with the second gear 7, it will drive the transmission gear set on the sliding shaft 10 to rotate, and then drive the spring 8 to contract, converting kinetic energy into elastic potential energy for storage. In this process, the spring 8 gradually deforms as it contracts, and when it contracts to a certain extent, it will pull the sliding shaft 10 to move toward the end close to the cleaning brush 3. After moving, the first transmission gear 12 is disengaged from the second gear 7, and the second transmission gear 13 is just meshed with the output gear 14. At this time, the spring 8 begins to release the stored elastic potential energy, driving the second transmission gear 13 to rotate. The second transmission gear 13 is meshed with the output gear 14 to transfer the kinetic energy to the output shaft 15. The rotation of the output shaft 15 drives the crank 16 to make a circular motion, and the crank 16 drives the sliding block 18 to slide back and forth in the slideway 19 through the connecting rod 17, so that the cleaning brush 3 fixed on the sliding block 18 wipes the lens of the camera 2.

[0072] When the spring 8 is releasing the stored elastic potential energy, when the deformation force is less than the tension of the coil spring, the coil spring pulls the sliding shaft 10 to move toward the end away from the cleaning brush 3. After the movement, the second transmission gear 13 is disengaged from the output gear 14, and the first transmission gear 12 is engaged with the second gear 7. Then the spring 8 resumes the energy storage state.

[0073] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
