Description

Technical Field

[0001] The utility model relates to the field of underground coal mine monitoring, and more specifically, to an intelligent monitoring and fault early warning device for underground coal mine ventilation. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. Underground ventilation in coal mines is very important. During the ventilation process, it is often necessary to monitor data such as the gas concentration inside the pipeline.

[0003] Existing device technology uses sensors for monitoring. In order to ensure the stability of the sensors, regular inspection and maintenance of the sensors are required. In actual use, when a fault occurs in the underground equipment of the coal mine or the internal environmental parameters of the mine change, the sensor converts the signal, and then the alarm light flashes to notify the staff. Although the purpose of fault reporting can be achieved, if the staff is far away from the machine body, they need to run a certain distance to observe the flashing of the alarm light. This process is time-consuming and labor-intensive, inconvenient, and has certain limitations when used.

[0004] Therefore, in order to solve the above problems, an intelligent monitoring and fault warning device for underground ventilation in coal mines is proposed. Utility Model Content

[0030] Example:

[0031] See also Figure 1-6A coal mine underground ventilation intelligent monitoring and fault warning device includes a body 1, a base 21 is fixedly connected to the top of the body 1, a second sector gear 22 is rotatably connected to the inside of the base 21, a speed change gear 27 is meshed on one side of the second sector gear 22, the speed change gear 27 is rotatably connected to the inside of the base 21, a rotating block 23 is rotatably connected to the middle part of the inside of the base 21, and vibration blocks 24 are provided on both sides of the rotating block 23, the bottom of the rotating block 23 is meshed with the top of the speed change gear 27, and the top of the second sector gear 22 is fixedly connected to Spring 28, the end of spring 28 is in contact with the inner wall of base 21. In this solution, the second sector gear 22 is meshed with the lower part of speed gear 27, and the rotating block 23 is meshed with the upper part of speed gear 27. Because the diameter of speed gear 27 is larger at the upper part than at the lower part, when the second sector gear 22 drives the speed gear 27 to rotate, the rotating block 23 will rotate at a faster speed. During the rotation process of the second sector gear 22, the spring 28 will be squeezed. After being squeezed, the spring 28 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy.

[0032] See also Figure 1-6 An outer cover 25 is fixedly connected to the top of the base 21, and an impact block 26 is fixedly connected to the inner wall of the outer cover 25. In this solution, when the rotating block 23 rotates, the vibration block 24 will continuously hit the impact block 26, and then the vibration block 24 will vibrate after the collision, thereby making a sound.

[0033] See also Figure 1-6 A turntable 16 is rotatably connected to the top of the body 1, and a fan-shaped gear 17 is slidably connected to the top of the turntable 16. The middle part of the fan-shaped gear 17 is rotatably connected to the top of the body 1. In this solution, when the turntable 16 rotates, it drives the fan-shaped gear 17 to swing back and forth with the connection between itself and the body 1 as the center.

[0034] See also Figure 1-6 The motor 2 is fixedly connected to the inside of the body 1, and the output end of the motor 2 passes through the top of the body 1 and is fixedly connected to the turntable 16. In this solution, the motor 2 provides power for the rotation of the turntable 16.

[0035] See also Figure 1-6 A rack 18 is slidably connected to the top of the body 1, and the rack 18 is meshed with one side of the No. 1 sector gear 17. A protrusion 19 is fixedly connected to the outer wall of the rack 18. In this solution, when the No. 1 sector gear 17 swings back and forth with the connection between itself and the body 1 as the center, it will drive the rack 18 to move back and forth above the body 1. Because one side of the rack 18 is fixedly connected with the protrusion 19, as the rack 18 moves, the protrusion 19 will squeeze the end of the No. 2 sector gear 22 and drive the No. 2 sector gear 22 to rotate.

[0036] See also Figure 1-6 An integrated sensor 12 and a battery 13 are installed inside the body 1, and a display screen 11 is provided outside the body 1. In this solution, the battery 13 provides power for the operation of the display screen 11, the integrated sensor 12 and the motor 2. The integrated sensor 12 is a sensing device that integrates a temperature sensor, a humidity sensor, a dust sensor and a current sensor, and can detect multiple parameters inside the mine.

[0037] See also Figure 1-6 A heat dissipation hole 15 is provided on one side of the body 1, and a warning light 14 is installed above the body 1. In this solution, the heat dissipation hole 15 is used to dissipate heat from the inside of the body 1. When an external coal mine underground equipment fails, the warning light 14 will light up and remind the staff.

[0038] Working principle: When the power of the peripheral coal mine underground equipment fails, the integrated sensor 12 senses the fault and its internal transmitter will send a signal to the warning light 14 and the motor 2 at the same time, and then the warning light 14 will light up. After receiving the signal, the output end of the motor 2 will rotate, and the rotation of the output end of the motor 2 will drive the turntable 16 to rotate. When the turntable 16 rotates, it will drive the No. 1 sector gear 17 to swing back and forth with the connection between itself and the body 1 as the center. When the No. 1 sector gear 17 swings back and forth with the connection between itself and the body 1 as the center, it will drive the rack 18 to move back and forth above the body 1. Because a protrusion 19 is fixedly connected to one side of the rack 18, as the rack 18 moves, the protrusion 19 will squeeze the end of the No. 2 sector gear 22 and drive the No. 2 sector gear 22 to rotate. The second sector gear 22 is meshed with the lower part of the speed gear 27, and the rotating block 23 is meshed with the upper part of the speed gear 27. When the rotating block 23 rotates, the vibrating block 24 will continuously hit the impact block 26. Then the vibrating block 24 will vibrate after the collision, thereby making a sound, thereby completing the fault alarm prompt. Because the diameter of the speed gear 27 is larger than the lower part, when the second sector gear 22 drives the speed gear 27 to rotate, the rotating block 23 will rotate at a faster speed. During the rotation process of the second sector gear 22, the spring 28 will be squeezed. After being squeezed, the spring 28 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. After the protrusion 19 is disengaged from one end of the second sector gear 22, the spring 28 in the elastic deformation state will reset, thereby driving the second sector gear 22 to reset.

[0039] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
