Description

Technical Field

[0001] The invention relates to the technical field of earthquake monitoring, and in particular to a coal mine earthquake early warning monitoring instrument. Background Art

[0002] The earthquake early warning monitor monitors the seismic activities in coal mines in real time, including the intensity, frequency, duration and other parameters of seismic waves, and can detect tiny seismic signals in time, providing basic data for earthquake early warning. Through high-precision sensors such as seismic sensors and stress sensors, it captures various physical signal changes generated by crustal movement, so as to accurately judge the occurrence and development trend of earthquakes.

[0003] At present, in the existing technology, the monitor only relies on simple sealing rings or sealing covers for dust-proof sealing. In the case of strong vibrations such as earthquakes, these sealing methods may easily fail, resulting in the entry of impurities such as dust. The existing protective devices cannot respond quickly and complete protection in the first time of an earthquake. They may easily become loose or shifted in a vibrating environment, which may lead to poor protection effects. Impurities such as dust still have the opportunity to enter the detection port, affecting the reliability and stability of the monitor. In view of this, we propose a coal mine earthquake early warning monitor. Summary of the invention

[0040] In the embodiment of the present invention, in order to ensure the stable performance of the monitor 1 and extend its service life, a protective shell 61 is fixedly connected to the outer wall of the monitor 1. A recess 601 and a through hole 62 are provided on the surface of the protective shell 61. A sliding rod 64 is slidably connected in the through hole 62. The sliding rod 64 is slidably connected in the circular hole 603 provided in the fixed plate 63. The fixed plate 63 is fixedly connected to the protective shell 61. The fixed plate 63 is elastically connected to the extrusion block 66 through a spring 1 65. The extrusion block 66 is fixedly connected to the sliding rod 64. A movable groove 67 is provided in the circular hole 603. When an earthquake occurs in the coal mine, the extrusion block 66 is first squeezed and protruded. The extrusion block 66 drives the sliding rod 64 to slide downward toward the fixed plate 63. The movable groove 67 is slidably connected to an oblique block 68. The oblique block 68 is fixedly connected to the trapezoidal block 69. The trapezoidal block 69 is elastically connected to the movable groove 67 through a spring 2 611.

After the inflatable airbag 614 expands, it can squeeze and close some gaps and channels, and can automatically start the sealing protection mechanism when an earthquake occurs. When the vibration generated by the earthquake causes the squeezing block 66 to protrude first, the automatic triggering feature ensures that in an emergency situation of a sudden earthquake, the monitor 1 can be quickly protected, and the expansion of the inflatable airbag 614 is used to seal the monitor 1, reducing the chance of dust and other impurities entering the monitor 1.

[0041] In the embodiment of the present invention, in order to protect the key parts of the monitor 1 and improve the reliability and stability of the monitor 1, the sliding protection component 7 includes a sensor 71, the inner wall of the protective shell 61 is fixedly connected with the sensor 71, the sensor 71 is electrically connected to the motor 72, the output shaft of the motor 72 is fixedly connected to the transmission wheel 1 73, after the inflatable airbag 614 is inflated, the sensor 71 detects that the local air pressure inside the monitor 1 is increased or decreased due to the expansion of the inflatable airbag 614, and sends an electrical signal to the motor 72, thereby turning on the motor 72, and the transmission wheel 1 73 is connected to the transmission wheel 2 75 through the transmission belt 74, and the transmission wheel 1 73 and the transmission wheel 2 75 are both fixedly connected with The output shaft of the motor 72 drives the transmission wheel 1 73 to rotate, and the transmission wheel 1 73 transmits power to the transmission wheel 2 75 through the transmission belt 74, so that the transmission wheel 2 75 rotates synchronously, and the rotating disk 76 also rotates accordingly. The rotating disk 76 is rotatably connected to a connecting plate 77, and the end of the connecting plate 77 away from the rotating disk 76 is rotatably connected to a protective plate 78. When the rotating disk 76 rotates, it drives the connecting plate 77 to move, and the protective plate 78 is slidably connected in the make way slot 601, and two groups of protective plates 78 are provided. Driven by the connecting plate 77, the two groups of protective plates 78 slide toward each other along the make way slot 601, gradually covering the detection port 101 of the monitor 1, thereby protecting the detection port 101.

[0042] In the embodiment of the present invention, in order to ensure the continuous and effective protection of the detection port 101, the clamping assembly 8 includes a protrusion 81, the outer wall of the protective plate 78 is fixedly connected with the protrusion 81, the surface of the detection port 101 is fixedly connected with an extension plate 82, and the surface of the extension plate 82 is provided with an auxiliary groove 83, the protrusion 81 of the protective plate 78 will gradually approach the auxiliary groove 83 on the extension plate 82 as the protective plate 78 moves, the auxiliary groove 83 is fixedly connected with an elastic block 84, the inner wall of the elastic block 84 is fixedly connected with a spring 85, when no external force is applied, the elastic block 84 is in the spring 85. 5, it is in a natural extension state and partially extends out of the auxiliary groove 83 to form a blocking structure. When the protrusion 81 contacts the elastic block 84, it will squeeze the elastic block 84 to shrink it into the auxiliary groove 83. At the same time, the spring three 85 is compressed to store elastic potential energy. The clamping assembly 8 is provided with multiple groups. As the protective plate 78 continues to slide, the protrusion 81 will pass the blocking position of the elastic block 84. The elastic block 84 returns to its original state under the elastic force of the spring three 85 and clamps the protrusion 81. The clamping assembly 8 is provided with multiple groups, which are evenly distributed at the contact position between the protective plate 78 and the extension plate 82. Multi-point clamping can make the protective plate 78 more firmly fixed in the protective position, disperse the effect of external force on a single clamping point, and further enhance the stability of the protective plate 78. Even in the case of strong vibration, it can effectively prevent the protective plate 78 from loosening or falling off, ensuring continuous and effective protection of the detection port 101. The clamping assembly 8 can automatically lock after the protective plate 78 slides into place without additional operation, ensuring that the protective plate 78 can stably remain in the protective position in a vibrating environment such as an earthquake, effectively preventing the detection port 101 from being exposed to the outside, and preventing dust, debris, etc. from entering the detection port 101 and affecting the normal operation of the monitor 1, effectively preventing the protective plate 78 from loosening or falling off, and ensuring continuous and effective protection of the detection port 101.

[0043] In the present invention, when an earthquake occurs in a coal mine, the protruding extrusion block 66 is squeezed first, and the extrusion block 66 drives the sliding rod 64 to slide downward in the direction of the fixed plate 63. The sliding rod 64 slides into the circular hole 603 of the fixed plate 63, squeezing the oblique block 68, which thereby contracts inward, driving the fixedly connected trapezoidal block 69 to contract synchronously, and the sliding connection of the trapezoidal block 69 causes the rotating wheel 612 to gradually rise, and under the limit of the limit hole 610, the lifting rod 613 gradually moves toward the inner wall of the protective shell 61. The airbag 614 rises and squeezes the airbag 614. After the airbag 614 expands, it can squeeze and close some gaps and channels, reducing the chance of dust and other impurities entering the monitor 1, thereby ensuring the stable performance of the monitor 1 and extending its service life. After the airbag 614 expands, the sensor 71 detects that the local air pressure inside the monitor 1 increases or decreases due to the expansion of the airbag 614, and sends an electrical signal to the motor 72, thereby turning on the motor 72. The output shaft of the motor 72 drives the transmission wheel 1 73 to rotate. The transmission wheel 1 73 transmits power to the transmission wheel 2 75 through the transmission belt 74, so that the transmission wheel 2 75 rotates synchronously, and the rotating disk 76 also rotates accordingly. When the rotating disk 76 rotates, it drives the connecting plate 77 to move. Driven by the connecting plate 77, the two sets of protective plates 78 slide toward each other along the yielding groove 601, which can respond to earthquake disasters in the first time, protect the key parts of the monitor 1 in time, cover the detection port 101 of the monitor 1, and realize the protection of the detection port 101. With the movement of plate 78, when the protrusion 81 contacts the elastic block 84, it will squeeze the elastic block 84 and make it shrink into the auxiliary groove 83. At the same time, the spring three 85 is compressed to store elastic potential energy. As the protective plate 78 continues to slide, the protrusion 81 will pass the blocking position of the elastic block 84. The elastic block 84 will return to its original state under the elastic force of the spring three 85 and jam the protrusion 81, thereby fixing the protective plate 78 in the protective position to prevent it from accidentally sliding due to vibration and the like, thereby ensuring stable protection of the detection port 101.
