Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safety warning lighting device for coal mines, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A safety warning lighting device for coal mines, including a chassis, further including a protection device and an ash removal device. A conical rod is fixedly installed at the bottom of the chassis, and an electric telescopic rod is arranged inside the chassis; wherein, the protection device includes an elastic telescopic rod, a warning light, a short plate, an L-shaped sliding rod, a trapezoidal block, a long rod, a protective cover, an elastic telescopic connecting rod and a push plate. The warning light is protected by the protective cover. When a relatively large gravel hits the protective cover, it will push the protective cover to move downward. The downward movement of the protective cover will drive the long rod to move downward. The downward movement of the long rod will contact the inclined surface of the trapezoidal block, preventing the impact from causing the outer shell of the warning light to crack or the internal components to be damaged, affecting normal use. The elastic telescopic rod is fixedly installed at the output end of the electric telescopic rod, the warning light is fixedly installed at the free end of the elastic telescopic rod, the short plate is fixedly installed at the free end of the elastic telescopic rod, the L-shaped sliding rod is slidably installed at the fixed end of the elastic telescopic rod, the trapezoidal block is fixedly installed on the surface of the L-shaped sliding rod, the long rod slidably penetrates through the top of the chassis, the protective cover is fixedly installed at the top of the long rod, a groove is opened inside the chassis, the elastic telescopic connecting rod is fixedly installed on the inner wall of the groove, and the push plate is fixedly installed at the free end of the elastic telescopic connecting rod. When the warning light enters the inside of the chassis, the elastic telescopic connecting rod will push the push plates to move towards each other, and the movement of the push plates towards each other will close the outlet, preventing the falling gravel from entering the chassis and causing damage to the internal instruments, affecting normal use.

[0007] According to the above technical solution, a first spring is arranged between the L-shaped sliding rod and the elastic telescopic rod, and a second spring is arranged between the long rod and the chassis. The first spring drives the L-shaped sliding rod to reset, and the second spring drives the long rod to reset.

[0008] According to the above technical solution, the ash removal device includes a sliding plate, a spiral rod, an L-shaped rod, a rotating cylinder and a brush. The electric telescopic rod drives the elastic telescopic rod to move downward, the downward movement of the elastic telescopic rod drives the warning light to move downward, and at the same time when the warning light moves downward, the electric telescopic rod will drive the sliding plate to move downward. The sliding plate is fixedly installed at the output end of the electric telescopic rod, the spiral rod slidably penetrates through the surface of the sliding plate, the L-shaped rod is fixedly installed at the bottom of the sliding plate, the L-shaped rod slides in the spiral groove, the rotating cylinder is fixedly installed at the top of the spiral rod, and the brush is fixedly installed on the surface of the rotating cylinder, preventing coal ash from adhering to the surface of the warning light, resulting in a decrease in illuminance and reducing the visibility of the warning signal.

[0009] According to the above technical solution, a short round rod is fixedly installed at the top of the rotary drum, a support frame is fixedly installed on the inner wall of the chassis, a convex block is fixedly installed on the surface of the support frame, the surface of the short round rod contacts the convex block, the rotation of the rotary drum will drive the short round rod to rotate, during the rotation of the short round rod, it will contact the convex block, the short round rod will impact the convex block to generate vibration, and the coal ash inside the brush will be shaken off through the vibration, preventing the coal ash from adhering to the surface of the brush. When cleaning the surface of the warning light, part of the coal ash will be brought to the surface of the warning light, affecting the visibility of the warning signal.

[0010] According to the above technical solution, a dust reduction device and a buffer device are further included. The dust reduction device includes a water tank, a delivery pipe, a pneumatic box, an air inlet and a pneumatic plate. When the sliding plate moves downward, it drives the pneumatic box to move downward. When the pneumatic box moves downward, the gas inside it will decrease, and the gas inside the chassis is sucked into the pneumatic box through the air inlet. The water tank is fixedly installed at the top of the inner wall of the chassis, the delivery pipe is fixedly installed at the bottom of the water tank, the pneumatic box is fixedly installed on the surface of the sliding plate, the air inlet is fixedly installed on the surface of the pneumatic box, and the pneumatic plate is fixedly installed at the bottom of the delivery pipe, preventing the coal ash cleaned down from floating in the air and adhering to the surface of the warning light again.

[0011] According to the above technical solution, a water storage tank is provided inside the pneumatic plate, a water dripping port is provided at the bottom of the water storage tank, a sliding plate is slidably installed at the bottom of the pneumatic plate, a triangular plate is fixedly installed at the bottom of the inner wall of the pneumatic box, and a third spring is arranged between the pneumatic plate and the sliding plate. When the pneumatic box moves downward, it drives the triangular plate to move downward. When the triangular plate moves downward, it will disengage from the contact with the sliding plate. When the sliding plate moves away from the water dripping port, the water dripping port will be opened for dripping. The coal ash is dust-reduced through dripping, preventing the coal ash from floating again inside the pneumatic box and entering the chassis, affecting the visibility of the warning signal. The third spring drives the sliding plate to reset, preventing the sliding plate from continuously blocking the water dripping port.

[0012] According to the above technical solution, the buffer device includes support legs and a disc. The chassis is supported by the support legs and the disc. The support legs are fixedly installed on the surface of the tapered rod, and the disc is fixedly installed at the bottom of the support legs, preventing the chassis from being easily toppled due to unstable placement positions, resulting in damage to the internal parts.

[0013] According to the above technical solution, a hydraulic cylinder is fixedly installed on the surface of the chassis. A round plate is slidably installed inside the hydraulic cylinder. A hydraulic rod is fixedly installed on the surface of the round plate. A buffer plate is fixedly installed on the surface of the hydraulic rod. A non-Newtonian fluid is provided inside the hydraulic cylinder. The buffer plate will push the hydraulic rod to move into the hydraulic cylinder. When the hydraulic rod moves into the hydraulic cylinder, it drives the round plate to move into the hydraulic cylinder. When the Newtonian fluid is suddenly impacted, the liquid will become viscous, which can effectively absorb and disperse the impact energy, preventing the huge acting force caused by the impact from damaging the internal parts of the chassis and affecting the normal use of the warning light.

[0014] The present invention provides a safety warning lighting device for coal mines, which has the following beneficial effects: (1) This type of safety warning lighting equipment for coal mines protects the warning light through a protective cover. When larger pieces of gravel hit the protective cover, the protection effect will be triggered, and the long rod will push the trapezoidal block to release the limit on the short plate, so that the elastic telescopic rod can drive the warning light to move quickly into the chassis under its own elastic force to prevent the impact from causing the warning light housing to break or internal parts to be damaged, affecting normal use. At the same time, when the warning light drops, the elastic telescopic connecting rod will push the push plate to close the outlet to prevent debris from falling into the chassis and causing damage to the internal equipment, affecting normal use.

[0015] (2) This type of safety warning lighting equipment for coal mines can retract the warning light when it is not needed. The warning light can be driven down by the electric telescopic rod to avoid long-term exposure of the warning light to the outside, which would damage the warning light and reduce the service life of the warning light. While descending, the spiral rod will be driven to rotate, and the brush will be driven to rotate through the rotation of the spiral rod to clean the coal dust on the surface of the warning light, preventing the coal dust from adhering to the surface of the warning light, resulting in a decrease in light intensity and reduced visibility of the warning signal. At the same time, the rotating drum will hit the bumps and generate vibrations during rotation, shaking off the coal dust inside the brush and improving the cleaning effect.

[0016] (3) This type of safety warning lighting equipment for coal mines uses a brush to rotate to clean the coal ash while driving the air pressure box downward through the sliding plate, so that the gas inside the box enters the air pressure box and the cleaned coal ash is sucked into the air pressure box through the air intake port to prevent the cleaned coal ash from floating in the air and adhering to the surface of the warning light again. At the same time, the downward movement of the air pressure box will drive the triangular plate down, and the triangular plate will be out of contact with the slide plate when it descends. The spring slide plate will be reset to open the drip port, and the coal ash will be reduced by dripping water to prevent the coal ash from floating into the box inside the air pressure box and affecting the visibility of the warning signal.

[0017] (4) This type of coal mine safety warning lighting equipment supports the chassis through supporting legs and discs to prevent it from tipping over due to unstable placement. When tipping over occurs, the buffer plate will first contact the ground, which can reduce the force caused by the impact. At the same time, the impact will drive the hydraulic rod to push the non-Newtonian fluid inside the hydraulic cylinder. The physical properties of the non-Newtonian fluid itself will alleviate the reaction force caused by the impact, preventing the huge force caused by the impact from causing damage to the parts inside the chassis and affecting the normal use of the warning light.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-6, an embodiment of the present invention is: a safety warning lighting device for coal mines, including a chassis 1, and further including a protection device and an ash removal device.

The warning light 42 is protected by the protective cover 47. When a relatively large piece of gravel hits the protective cover 47, it will push the protective cover 47 to move downward. The downward movement of the protective cover 47 will drive the long rod 46 to move downward. The downward movement of the long rod 46 will contact the inclined surface of the trapezoidal block 45, and the long rod 46 will push the trapezoidal block 45 to move away from the long rod 46, preventing the outer shell of the warning light 42 from cracking or the internal components from being damaged due to the impact, which affects normal use. The elastic telescopic rod 41 is fixedly installed at the output end of the electric telescopic rod 3, the warning light 42 is fixedly installed at the free end of the elastic telescopic rod 41, the short plate 43 is fixedly installed at the free end of the elastic telescopic rod 41, the L-shaped sliding rod 44 is slidably installed at the fixed end of the elastic telescopic rod 41, the trapezoidal block 45 is fixedly installed on the surface of the L-shaped sliding rod 44, the long rod 46 slidably penetrates through the top of the chassis 1, the protective cover 47 is fixedly installed at the top of the long rod 46, a groove is opened inside the chassis 1, the elastic telescopic link 48 is fixedly installed on the inner wall of the groove, the push plate 49 is fixedly installed at the free end of the elastic telescopic link 48. When the warning light 42 enters the inside of the chassis 1, the elastic telescopic link 48 will push the push plate 49 to move towards each other, and the movement of the push plate 49 towards each other will close the outlet, preventing the falling gravel from entering the chassis 1 and causing damage to the internal instruments, which affects normal use.

[0022] A first spring is arranged between the L-shaped sliding rod 44 and the elastic telescopic rod 41, and a second spring is arranged between the long rod 46 and the chassis 1. The L-shaped sliding rod 44 is driven to reset by the first spring, and the long rod 46 is driven to reset by the second spring.

[0023] The ash removal device includes a sliding plate 51, a screw rod 52, an L-shaped rod 53, a rotating cylinder 54 and a brush 55. The electric telescopic rod 3 drives the elastic telescopic rod 41 to move downward. The downward movement of the elastic telescopic rod 41 drives the warning light 42 to move downward. While the warning light 42 moves downward, the electric telescopic rod 3 will drive the sliding plate 51 to move downward. The sliding plate 51 is fixedly installed at the output end of the electric telescopic rod 3. The screw rod 52 slidably penetrates through the surface of the sliding plate 51. The L-shaped rod 53 is fixedly installed at the bottom of the sliding plate 51. The L-shaped rod 53 slides in the spiral groove. The rotating cylinder 54 is fixedly installed at the top of the screw rod 52. The brush 55 is fixedly installed on the surface of the rotating cylinder 54, preventing coal ash from adhering to the surface of the warning light 42, resulting in a decrease in the illumination intensity and reducing the visibility of the warning signal.

[0024] A circular short rod 56 is fixedly installed at the top of the rotary drum 54. A support frame 57 is fixedly installed on the inner wall of the chassis 1. A convex block 58 is fixedly installed on the surface of the support frame 57. The surfaces of the circular short rod 56 and the convex block 58 are in contact. The rotation of the rotary drum 54 will drive the circular short rod 56 to rotate. During the rotation of the circular short rod 56, it will contact the convex block 58, and the circular short rod 56 will hit the convex block 58 to generate vibration. The coal ash inside the brush 55 will be shaken off through the vibration, preventing the coal ash from adhering to the surface of the brush 55. When cleaning the surface of the warning light 42, some coal ash will be brought to the surface of the warning light 42, affecting the visibility of the warning signal.

[0025] When this embodiment works, the warning light 42 is protected by the protective cover 47. When a larger gravel hits the protective cover 47, it will push the protective cover 47 to move downward. The downward movement of the protective cover 47 will drive the long rod 46 to move downward. The downward movement of the long rod 46 will contact the inclined surface of the trapezoidal block 45, and the long rod 46 will push the trapezoidal block 45 to move away from the long rod 46. The movement of the trapezoidal block 45 away from the long rod 46 will drive the L-shaped sliding rod 44 to move away from the long rod 46. The movement of the L-shaped sliding rod 44 away from the long rod 46 will release the limit on the short plate 43. Under the elastic force of the elastic telescopic rod 41 itself, it will drive the warning light 42 to contract into the chassis 1 to prevent the outer shell of the warning light 42 from cracking or the internal components from being damaged due to the impact, affecting the normal use. At the same time, when the warning light 42 enters the chassis 1, the elastic telescopic link 48 will push the push plates 49 to move towards each other. The movement of the push plates 49 towards each other will close the outlet, preventing the falling gravel from entering the chassis 1 and causing damage to the internal instruments, affecting the normal use.

[0026] When the warning light 42 is not in use, the warning light 42 can be recycled. The electric telescopic rod 3 drives the elastic telescopic rod 41 to move downward. The downward movement of the elastic telescopic rod 41 drives the warning light 42 to move downward. At the same time when the warning light 42 moves downward, the electric telescopic rod 3 will drive the sliding plate 51 to move downward. The downward movement of the sliding plate 51 will drive the L-shaped rod 53 to move downward. The downward movement of the L-shaped rod 53 drives the screw rod 52 to rotate. The rotation of the screw rod 52 will drive the rotary drum 54 to rotate. The rotation of the rotary drum 54 will drive the brush 55 to rotate. The coal ash attached to the surface of the warning light 42 will be cleaned off through the rotation of the brush 55, preventing the coal ash from adhering to the surface of the warning light 42, resulting in a decrease in the light intensity and reducing the visibility of the warning signal. At the same time, the rotation of the rotary drum 54 will drive the circular short rod 56 to rotate. During the rotation of the circular short rod 56, it will contact the convex block 58, and the circular short rod 56 will hit the convex block 58 to generate vibration. The coal ash inside the brush 55 will be shaken off through the vibration, preventing the coal ash from adhering to the surface of the brush 55. When cleaning the surface of the warning light 42, some coal ash will adhere to the surface of the warning light 42, affecting the visibility of the warning signal.

[0027] Please refer to Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, a dust-removing device and a buffer device are further included. The dust-removing device includes a water tank 61, a delivery pipe 62, a pneumatic box 63, an air inlet 64, and a pneumatic plate 65. When the sliding plate 51 moves downward, it drives the pneumatic box 63 to move downward. The gas inside the pneumatic box 63 will decrease when it moves downward. The gas inside the chassis 1 is sucked into the pneumatic box 63 through the air inlet 64. The water tank 61 is fixedly installed at the top of the inner wall of the chassis 1, the delivery pipe 62 is fixedly installed at the bottom of the water tank 61, the pneumatic box 63 is fixedly installed on the surface of the sliding plate 51, the air inlet 64 is fixedly installed on the surface of the pneumatic box 63, and the pneumatic plate 65 is fixedly installed at the bottom of the delivery pipe 62 to prevent the coal ash cleaned down from floating in the air and adhering to the surface of the warning light 42 again.

[0028] A water storage tank is provided inside the pneumatic plate 65, and a water dripping port is provided at the bottom of the water storage tank. A sliding plate 66 is slidably installed at the bottom of the pneumatic plate 65. A triangular plate 67 is fixedly installed at the bottom of the inner wall of the pneumatic box 63. A third spring is provided between the pneumatic plate 65 and the sliding plate 66. When the pneumatic box 63 moves downward, it drives the triangular plate 67 to move downward. When the triangular plate 67 moves downward, it will disengage from the sliding plate 66. When the sliding plate 66 moves away from the water dripping port, it will open the water dripping port for dripping water. The coal ash is dusted by dripping water to prevent the coal ash from floating again inside the pneumatic box 63 and entering the chassis 1, which affects the visibility of the warning signal. The third spring drives the sliding plate 66 to reset to prevent the sliding plate 66 from continuously blocking the water dripping port.

[0029] The buffer device includes support legs 71 and a disc 72. The chassis 1 is supported by the support legs 71 and the disc 72. The support legs 71 are fixedly installed on the surface of the tapered rod 2, and the disc 72 is fixedly installed at the bottom of the support legs 71 to prevent the chassis 1 from being easily toppled due to unstable placement positions, resulting in damage to the internal parts.

[0030] A hydraulic cylinder 73 is fixedly installed on the surface of the chassis 1. A circular plate 74 is slidably installed inside the hydraulic cylinder 73. A hydraulic rod 75 is fixedly installed on the surface of the circular plate 74. A buffer plate 76 is fixedly installed on the surface of the hydraulic rod 75. A non-Newtonian fluid is provided inside the hydraulic cylinder 73. The buffer plate 76 will push the hydraulic rod 75 to move inside the hydraulic cylinder 73. When the hydraulic rod 75 moves inside the hydraulic cylinder 73, it drives the circular plate 74 to move inside the hydraulic cylinder 73. When the circular plate 74 moves inside the hydraulic cylinder 73, it will impact the non-Newtonian fluid inside the hydraulic cylinder 73. When the Newtonian fluid is suddenly impacted, the liquid will become viscous, which can effectively absorb and disperse the impact energy and prevent the huge force caused by the impact from damaging the internal parts of the chassis 1 and affecting the normal use of the warning light 42.

[0031] During the operation of this embodiment, the sliding plate 51 moves downward to drive the air pressure box 63 to move downward. As the air pressure box 63 moves downward, the gas inside it will decrease. The gas inside the chassis 1 is sucked into the air pressure box 63 through the air suction port 64, and at the same time, the coal ash cleaned from the inside of the chassis 1 is sucked into the air pressure box 63, preventing the coal ash from floating in the air and adhering to the surface of the warning light 42 again. At the same time, when the air pressure box 63 moves downward, it will drive the triangular plate 67 to move downward. When the triangular plate 67 moves downward, it will disengage from the contact with the sliding plate 66. The sliding plate 66 is driven by the third spring to move away from the water dripping port. When the sliding plate 66 moves away from the water dripping port, it will open the water dripping port for water dripping. The coal ash is dusted by the water dripping to prevent the coal ash from floating again inside the air pressure box 63 and entering the chassis 1, affecting the visibility of the warning signal.

[0032] The chassis 1 is supported by the support legs 71 and the disc 72 to prevent the chassis 1 from tipping over easily due to unstable placement, which may cause damage to the internal parts. At the same time, when tipping occurs, first, the buffer plate 76 will come into contact with the ground first. The buffer plate 76 can slow down the acting force driven by the impact. At the same time, when being impacted, the buffer plate 76 will push the hydraulic rod 75 into the hydraulic cylinder 73. As the hydraulic rod 75 moves into the hydraulic cylinder 73, it will drive the round plate 74 to move into the hydraulic cylinder 73. When the round plate 74 moves into the hydraulic cylinder 73, it will impact the non-Newtonian fluid inside the hydraulic cylinder 73. When the non-Newtonian fluid is suddenly impacted, the liquid will become viscous, which can effectively absorb and disperse the impact energy, preventing the huge acting force caused by the impact from damaging the internal parts of the chassis 1 and affecting the normal use of the warning light 42.
