Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, in particular to a wireless charging positive pressure device for mining. Background Art

[0002] Intelligent mining is a major trend in coal mining. The "remote operation, unmanned inspection" mining model is gradually developing. Various inspection robots are being developed and applied continuously. However, the endurance and battery charging methods of inspection robots have been major factors restricting their development. Currently, mines use charging stations installed in the mine to charge the robots. However, due to the limited battery capacity, inspection robots cannot work underground for long periods of time. Repeated trips to the mine to recharge the batteries significantly reduce their work efficiency.

[0003] If wired charging is used underground, electric sparks may be generated at the moment the charging head contacts the device, which is absolutely not allowed underground. Wireless charging does not have the problem of generating electric sparks, but due to the presence of gas underground, wireless charging also has the possibility of causing gas explosions when used underground. Therefore, how to ensure that the inspection robot can be wirelessly charged in a gas-free environment needs to be solved urgently. Based on this, we propose a mine-use wireless charging positive pressure device. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0025] This embodiment proposes a wireless charging positive pressure device for mining, such as Figures 1 to 4 As shown, it includes a sealing cover 1, the lower end of the sealing cover 1 is fixedly installed in a set area underground by a supporting leg 10, the front end of the sealing cover 1 is provided with a warehouse entrance 2, and two sealing doors 3 slidingly assembled on the sealing cover 1 are symmetrically provided on both sides of the warehouse entrance 2, the inner cavity of the sealing cover 1 is installed with a slide 4 in the horizontal direction, and the other end of the slide 4 extends to the outside of the sealing cover 1, and an inspection robot 6 is slidingly assembled on the slide 4, and a wireless charging pile 5 compatible with the inspection robot 6 is also installed inside the sealing cover 1, and an induction area is set between the wireless charging pile 5 and the inspection robot 6. When the inspection robot 6 moves along the slide 4 to the induction area, the two sealing doors 3 make relative movement to form a closed chamber in the inner cavity of the sealing cover 1. Under a positive pressure environment, the inspection robot 6 performs wireless charging operations in the induction area.

[0026] In order to achieve a positive pressure environment in the closed chamber, we install a first air pipe 7 on one side of the sealing cover 1. Compressed air is continuously input into the closed chamber through the first air pipe 7. The pressure in the closed chamber is detected by a gas pressure sensor (not shown in the figure) installed in the closed chamber to ensure that the gas pressure in the closed chamber reaches the set value. In this embodiment, the input compressed air is drawn from the existing compressed air pipeline in the mine. The gas source in the compressed air pipeline is used to make the air pressure in the closed chamber higher than the outside, creating a positive pressure state, preventing flammable gases such as underground gas from entering the closed chamber, ensuring that the wireless charging is in a gas-free environment during operation, and there is no gas, creating a charging environment similar to that used on the well for the inspection robot 6.

[0027] Building on the above solution, the other end of first air pipe 7 is connected to the outlet of air pump 8, the inlet of which is connected to second air pipe 9. The other end of second air pipe 9 is connected to the existing compressed air pipeline in the mine. To further improve the safety of wireless charging, the other end of second air pipe 9 can be connected to an external air source to deliver safe gas into the closed chamber.

[0028] In order to ensure that the inspection robot 6 is in a stationary state when it is in the sensing area, a positioning base 11 is installed inside the sealing cover 1. The positioning base 11 is provided with a first positioning groove 12 adapted for the inspection robot 6 on the end face near the inspection robot 6. A first sensor 13 for sensing whether the inspection robot 6 has moved into position is installed in the first positioning groove 12. When the first sensor 13 senses that the inspection robot 6 is in position, the inspection robot 6 is just in the sensing area. In addition, a second positioning groove 61 is provided on the bottom surface of the inspection robot 6. The inner cavity of the sealing cover 1 is provided with a positioning block 62 that slides in the vertical direction. When the inspection robot 6 is in the sensing area, the positioning block 62 moves upward in the vertical direction until it moves into the second positioning groove 61, thereby achieving the vertical positioning of the inspection robot 6 and further preventing it from shaking during wireless charging. In this embodiment, the lower end of the positioning block 62 is fixedly connected to the piston rod of the telescopic rod 63. The telescopic rod 63 is fixedly installed in the sealing cover 1. The telescopic movement of the piston rod of the telescopic rod 63 drives the positioning block 62 to move upward and reset.

[0029] In addition, in order to prevent the compressed air input into the closed chamber from containing flammable gases such as gas, we installed an environmental sensor (not shown in the figure) in the closed chamber to detect whether there is flammable gas such as gas in the gas. When the detection judgment is passed, the inspection robot 6 will perform wireless charging operation.

[0030] In this embodiment, the two sealing doors 3 are driven to move relative to each other by a positive and negative threaded rod structure. Specifically, a slider 34 is installed on the upper ends of the two sealing doors 3. The two sliders 34 are slidably assembled in the upper track 33. The upper track 33 is fixedly mounted on the sealing cover 1. A positive and negative threaded rod 35 is threadedly inserted and connected between the two sliders 34. One end of the positive and negative threaded rod 35 is movably connected to the upper track 33, and the other end of the positive and negative threaded rod 35 is fixedly connected to the motor shaft of the motor 36. The motor 36 is fixedly mounted on the upper track 33. The lower end of the sealing door 3 is slidably assembled on the lower track 32, and the lower track 32 is fixedly mounted on the sealing cover 1. When the motor 36 is started, the motor shaft of the motor 36 rotates forward to drive the positive and negative threaded rod 35 to rotate forward. The positive and negative threaded rod 35 drives the two sliders 34 to move synchronously relative to each other, that is, the two sealing doors 3 move relative to each other to achieve the closure of the warehouse entrance 2. In order to improve the sealing degree of the closed chamber, we have opened grooves that are compatible with the slide 4 on the two sealing doors 3, and sealing strips 31 are installed around the grooves. When the sealing door 3 is in close contact with the slide 4, the sealing strip 31 is deformed under pressure and fills the gap between the sealing door 3 and the slide 4, thereby improving the sealing degree of the closed chamber.

[0031] Furthermore, the proposed wireless charging positive pressure device for mining can be applied to the underground charging of battery (bottleneck) locomotives currently used for underground transportation. Currently, underground battery locomotives pull mine carts in underground tunnels. When the batteries are depleted, they must be recharged above ground before returning to work underground. This device can be enlarged (to accommodate battery carts) and configured as an enclosed charging station. This allows battery carts to be charged locally underground, safely and at positive pressure, reducing labor intensity.
