DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

A movable telescopic rod 11, one end of the electric telescopic rod 11 passes through the second annular groove and extends to the inside of the fixed groove, one end of the electric telescopic rod 11 is fixedly installed with the fixed groove, a connecting block is fixedly installed at one end of the electric telescopic rod 11 away from the fixed groove, a collecting block 12 is fixedly installed at the bottom of the connecting block, a mounting opening is provided on the inner wall of the collecting block 12, a collecting pipe 13 is fixedly installed on one side of the mounting opening, a fan 14 is provided at one end of the collecting pipe 13, a fixing seat 15 is provided on the outside of the mounting block 7, a second sealing ring 16 is provided inside the fixing seat 15, a second electromagnet 17 is fixedly installed on the top of the second sealing ring 16, the first electromagnet 10 and the second electromagnet 17 are in a repulsive state, a moving groove is provided at the bottom of the second sealing ring 16, a connecting spring is fixedly installed inside the moving groove, and the connecting spring is fixedly installed on the inner wall of the bottom of the fixing seat 15.

[0028] The hanging ring 3 made of stainless steel can resist corrosion and high temperature, is safer in use, and improves the stability of the installation of the mining lamp. When the mining lamp is in use, the first heat sink 5 on the three heat dissipation columns 4 can be easily controlled by the driving structure to dissipate heat when the mining lamp is in use. The heat dissipation area at the bottom of the heat dissipation column 4 is increased by the second heat sink 6 to prevent the bottom of the heat dissipation column 4 from overheating near the lamp bead end, thereby affecting the service life of the heat dissipation column 4 and facilitating the improvement of the heat dissipation effect of the mining lamp. The electric telescopic rod 11 is installed through the second annular groove and the fixed groove. After the power is turned on, the first electromagnet 10 and the second electromagnet 17 are energized in a repulsive state, so that the first sealing ring 9 moves to the inside of the first annular groove, and the second sealing ring 16 is located inside the fixing seat 15. The connecting spring is compressed to expose the heat dissipation column 4. The electric telescopic rod 11 drives the collecting block 12 to move up and down through the driving structure, so that the fan 14 inside the collecting pipe 13 rotates forward, so that the fan 14 dissipates heat to the first heat sink 5 and the second heat sink 6 on the three heat dissipation columns 4. , it is convenient to use the first heat sink 5 and the second heat sink 6, the connection between the mounting block 7 and the lampshade 8 is protected by the fixing seat 15, and the cooling block 19 is used to further dissipate the heat of the heat column 4 close to the lamp bead, so as to reduce the situation that the first heat sink 5 at one end of the heat sink 4 close to the lamp bead is hotter and the other end is colder, so as to prevent uneven heat dissipation. When the mining lamp is not in use, the fan 14 is reversed, and when the electric telescopic rod 11 drives the collecting block 12 to move up and down, the dust on the first heat sink 5 and the second heat sink 6 is collected through the collecting pipe 13 and the collecting block 12, so as to prevent the accumulation of dust and the influence of the heat dissipation effect. When the power is off, the first electromagnet 10 and the second electromagnet 17 lose their magnetic force, and under the action of gravity, the first sealing ring 9 moves out of the first annular groove, and the second sealing ring 16 is pushed out of the fixing seat 15 by the action of the connecting spring, so that the first sealing ring 9 and the second sealing ring 16 are close to each other, so as to protect the heat sink 4, and prevent the accumulation of dust when not in use, so as to affect the heat dissipation of the mining lamp.

[0029] like Figures 1 to 4 As shown, a first limiting ring 18 is fixedly installed on the top of the first sealing ring 9, and the first limiting ring 18 is slidably connected to the inner wall of the first annular groove. The collecting block 12 is located at the bottom of the mounting block 7, and it is located at the top of the outer side of the heat dissipation column 4. The mounting port, the collecting pipe 13 and the fan 14 are distributed in a circular array with the collecting block 12 as the center. One end of the collecting pipe 13 and the fan 14 are located near the three heat dissipation columns 4, and the collecting block 12 is located at the top of the second heat sink 6.

[0030] When the first sealing ring 9 moves, the first limiting ring 18 is driven to move. The first limiting ring 18 prevents the first sealing ring 9 from completely moving out of the first annular groove, thereby making it inconvenient for the first sealing ring 9 to move. The movement of the collecting block 12 drives the movement of the collecting pipe 13 and the fan 14. The collecting pipe 13 and the fan 14 are distributed in an annular array to facilitate the heat dissipation of the first heat sink 5 and the second heat sink 6 on the heat dissipation column 4, and can also absorb the accumulated dust, further improving the heat dissipation effect of the heat dissipation column 4 on the industrial and mining lamp. Since the three heat dissipation columns 4 are close to each other, the first heat sink 5 is close to each other and has a small area, which is not convenient for heat dissipation. The collecting pipe 13 and the fan 14 are aligned with the close position of the three heat dissipation columns 4 to facilitate heat dissipation and improve the uniformity of heat dissipation.

[0031] like Figures 5 and 6 As shown, an annular opening is provided at the top of the fixing seat 15, the second electromagnet 17 is located at the annular opening and the top of the fixing seat 15, the second heat sink 6 is located on the inner side of the second electromagnet 17, and it is located at the top of the fixing seat 15, a refrigeration block 19 is provided on the top of the mounting block 7 and it is located outside the bottom ends of the three heat dissipation columns 4, a sealing gasket 20 is provided at the connection between the mounting block 7 and the lampshade 8, and the sealing gasket 20 is located at the bottom end inside the fixing seat 15.

[0032] The annular opening facilitates the movement of the second sealing ring 16 to drive the second electromagnet 17. When the mining lamp is powered on, the first electromagnet 10 and the second electromagnet 17 are powered on to repel each other, driving the first sealing ring 9 and the second sealing ring 16 to move relative to each other, so that the second sealing ring 16 moves to the inner wall of the fixed seat 15 through the annular opening, compressing the connecting spring inside the movable groove. When the mining lamp is powered off, the first electromagnet 10 and the second electromagnet 17 lose their magnetic force, and the second sealing ring 16 is pushed to move out of the fixed seat 15 through the action of the connecting spring, so as to facilitate the fit with the first sealing ring 9 moved out of the first annular groove, thereby facilitating the protection of the heat dissipation column 4 and facilitating the use of the heat dissipation column 4.

[0033] like Figures 7 and 8 As shown, one end of the three heat dissipation columns 4 passes through the top of the fixing seat 15 and extends to the inside of the fixing seat 15. A first mounting groove is provided on the side of the second sealing ring 16 close to the mounting block 7. Strip grooves are provided on the inner walls on both sides of the first mounting groove. A second mounting groove is provided on the inner wall of the top of the fixing seat 15. The second mounting groove is located on one side of the annular opening. A movable structure is provided on the opposite side of the first mounting groove and the second mounting groove. The movable structure is symmetrically arranged around the center of the fixing seat 15.

[0034] The movable structure is installed through the strip groove and the second installation groove. Through the symmetrically arranged movable structure, when the second sealing ring 16 moves on both sides of the sealing gasket 20, the sealing gasket 20 can be pressed tightly and the sealing performance can be enhanced.

[0035] like Figures 7 to 9As shown, the movable structure includes a first rack 21, a gear 22 is meshed on one side of the first rack 21, a rotating rod 23 is fixedly installed in the middle of the gear 22, a second rack 24 is meshed on one side of the gear 22, a compression spring 25 is fixedly installed on the top of the second rack 24, and a clamping ring 26 is fixedly installed on the bottom of the second rack 24.

[0036] When the second sealing ring 16 moves, it drives the first rack 21 to move upward, so that the gear 22 drives the rotating rod 23 to rotate, so that the second rack 24 drives the clamping ring 26 to move downward, and compresses the compression spring 25. When one end of the second sealing ring 16 moves to the outside of the fixing seat 15, the clamping ring 26 moves to the top of the sealing gasket 20 to press the sealing gasket 20, so that the sealing gasket 20 is fixed, which is convenient for improving the sealing between the mounting block 7 and the lampshade 8, and preventing water molecules in a humid environment from easily passing through the lampshade 8 into the interior of the mining lamp, which will cause the internal circuit of the mining lamp to be corroded by water molecules, causing damage to the lamp beads of the mining lamp.

[0037] like Figures 7 to 9 As shown, one side of the first rack 21 is fixedly installed with the strip groove, the top end of the second rack 24 is located in the second mounting groove, one end of the compression spring 25 is fixedly installed with the top of the second mounting groove, the compression spring 25 is in a compressed state, and both ends of the rotating rod 23 are rotatably connected with the support plate 28, the top end of the support plate 28 is fixedly installed with the top inner wall of the fixed seat 15, one end of the support plate 28 is located on one side of the second mounting groove, and the other end thereof is located in the second mounting groove.

[0038] The first rack 21 is installed through the strip groove, and the compression spring 25 is installed through the second installation groove. Since the compression spring 25 is in a compressed state, when the first rack 21 moves upward, it drives the gear 22 and the rotating rod 23 to rotate, so that the two ends of the rotating rod 23 rotate on one side of the support plate 28, so that the gear 22 remains stable when rotating, thereby moving the second rack 24 downward, so that the compression spring 25 is stretched, so that the second rack 24 drives the clamping ring 26 to move downward to compress the sealing gasket 20, thereby improving the sealing performance of the sealing gasket 20 on the connection between the mounting block 7 and the lampshade 8.

[0039] like Figures 5 to 7 As shown, a second limiting ring 29 is fixedly installed at the bottom end of the second sealing ring 16, and one side of the second limiting ring 29 is slidably connected to the inner wall of the fixing seat 15. The inner bottom end of the second sealing ring 16 is located below the first mounting groove and fits the outer side of the sealing gasket 20. The second rack 24 and the clamping ring 26 are located above the mounting block 7 and the sealing gasket 20.

[0040] The second limiting ring 29 facilitates the second sealing ring 16 to move along the inner wall of the fixing seat 15. When the second sealing gasket 20 is inside the fixing seat 15, its inner bottom end is located below the first mounting groove and fits with the outer side of the sealing gasket 20, so it is convenient to limit the two sides of the sealing gasket 20. When the second sealing gasket 20 does not move out of the fixing seat 15, the sealing gasket 20 can still be fixed, so that the sealing gasket 20 always remains in a sealed state.

[0041] like Figures 5 to 9 As shown, movable grooves are provided on the inner walls on both sides of the fixing seat 15, and a fixing spring 31 is fixedly installed inside the movable groove. A tightening block 30 is fixedly installed on one end of the fixing spring 31. The bottom of the tightening block 30 is slidably connected to the inner wall of the bottom of the fixing seat 15. The tightening block 30 is located on the outside of the second sealing ring 16, one side of the tightening block 30 is arc-shaped, and the top of the tightening block 30 close to the arc-shaped side is an inclined surface. The second limiting ring 29 is located between the tightening block 30 and the second sealing ring 16, and the tightening block 30 and the fixing spring 31 are symmetrically arranged with respect to the center of the fixing seat 15.

[0042] When the second sealing ring 16 drives the second limiting ring 29 to move upward, the tightening block 30 is no longer squeezed by the second sealing ring 16, and the tightening block 30 is pushed to move to both sides of the sealing gasket 20 by the action of the fixing spring 31. After the second sealing ring 16 moves and no longer presses the sealing gasket 20, the tightening block 30 can continue to limit the two sides of the sealing gasket 20, thereby further improving the sealing effect of the sealing gasket 20. When the second sealing ring 16 moves downward, one side of the second limiting ring 29 moves along the inclined surface of one side of the tightening block 30, squeezing the tightening block 30, so that the fixing spring 31 is compressed. When the tightening block 30 moves to the inner wall of the fixing seat 15, the second sealing ring 16 moves to the inside of the fixing seat 15, so that one side of the second sealing ring 16 limits the two sides of the sealing gasket 20 and can be away from the first sealing ring 9, so that the heat dissipation column 4 is exposed to dissipate heat for the industrial and mining lamp.

[0043] Working principle: When in use, after the power is turned on, the mining lamp starts to be used. Due to the repulsive effect between the first electromagnet 10 and the second electromagnet 17, the first sealing ring 9 is located inside the first annular groove, and the second sealing ring 16 is located inside the fixing seat 15. The first heat sink 5 and the second heat sink 6 on the heat dissipation column 4 are used to dissipate heat for the mining lamp. The electric telescopic rod 11 is started by the driving device to drive the collection block 12 to move up and down, so that the collection pipe 13 and the fan 14 inside the collection block 12 move at the same time, and the collection block 12 moves and the fan 14 inside the collection pipe 13 is started to rotate forward at the same time, so that the fan 14 dissipates heat for the first heat sink 5 and the second heat sink 6 on the three heat dissipation columns 4, which is convenient for the use of the first heat sink 5 and the second heat sink 6, and then the refrigeration block 19 is used to heat the heat column 4 close to the lamp bead end. Heat dissipation and cooling are performed in one step, and the situation that the heat sink at one end of the heat dissipation column 4 close to the lamp bead is hotter and the other end is colder is reduced, so as to prevent uneven heat dissipation. When the mining lamp is not in use, the fan 14 is reversed, and when the electric telescopic rod 11 drives the collecting block 12 to move up and down, the dust on the first heat dissipation fin 5 and the second heat dissipation fin 6 is collected through the collecting pipe 13 and the collecting block 12 to prevent dust accumulation from affecting the heat dissipation effect. When the power is off, the first electromagnet 10 and the second electromagnet 17 lose their magnetic force. Under the action of gravity, the first sealing ring 9 moves out of the first annular groove, and the second sealing ring 16 is pushed out of the fixing seat 15 by the action of the connecting spring, so that the first sealing ring 9 and the second sealing ring 16 are close to each other, so as to protect the heat dissipation column 4 and prevent dust from accumulating when not in use, thereby affecting the heat dissipation of the mining lamp.

[0044] When the second sealing ring 16 moves upward, it drives the first rack 21 to move upward, so that the gear 22 drives the rotating rod 23 to rotate along the support plate 28, so that the second rack 24 drives the clamping ring 26 to move downward, and compresses the compression spring 25. When one end of the second sealing ring 16 moves to the outside of the fixing seat 15, the clamping ring 26 moves to the top of the sealing gasket 20 to press the sealing gasket 20, so that the sealing gasket 20 is fixed, and when the second sealing ring 16 drives the second limiting ring 29 to move upward, the pressing block 30 is no longer squeezed by the second limiting ring 29. Under the push of the fixing spring 31, the pressing block 30 moves to both sides of the sealing gasket 20 to limit the two sides of the sealing gasket 20, thereby further improving the sealing effect of the sealing gasket 20, making it convenient to connect the mounting block 7 and the lampshade 8 tightly for easy use.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
