Description

Technical Field

[0001] The present invention relates to the technical field of coal mine dust detection, and in particular to a coal mine environmentally safe dust detection device and method thereof. Background Art

[0002] In the coal mining industry, safe production is always a top priority. Underground coal mines operate in a complex environment, and dust has always been a key threat to safe production and the health of miners. Coal mine dust not only causes occupational diseases such as pneumoconiosis, seriously endangering miners' health, but also easily triggers dust explosions, causing major safety accidents and resulting in huge losses to national property and miners' lives.

[0003] According to the technical effects of the existing technology and technical solutions, there are still areas that need to be optimized: the detection device cannot switch the cleaning state of the filter plate according to the humidity of the dust, which can easily cause the filter plate to be blocked. At the same time, it cannot effectively protect the detection rod when the filter plate is blocked. When the filter plate is blocked, the concentration of dust inside the vacuum tube will change, affecting the accuracy and reliability of the detection. Summary of the Invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0036] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0037] Example 1 Reference Figures 1 to 11 , which is the first embodiment of the present invention, provides a dust detection method for coal mine environmental safety.

[0038] The dust is sucked in through the dust suction pipe 201, and the dust concentration is then detected by the detection rod 104; After dry dust is sucked in, it can be cleaned and guided by the cleaning rod 207a; after wet dust is sucked in, it can be directly sprayed and cleaned by the second nozzle 208e; when the concentration of dust clogging the filter plate 204 changes, the detection rod 104 can be automatically protected and cleaned; A pressure component 208 is set at the bottom of the dust suction pipe 201. When the filter plate 204 moves downward, it will squeeze the pressure block 207d. The pressure block 207d pushes the pressure ring 208b through the pressure rod 208a, compressing the pressure spring 208d, so that the channel at the connection between the nozzle and the first nozzle 208c becomes larger, thereby increasing the water spray volume to meet the need for enhanced cleaning force due to dust blockage, further ensuring the efficient operation of the device.

[0039] Example 2 Reference Figure 1 、 2 , 5, 9, 10 and 12 are a second embodiment of the present invention, which provides a support mechanism 100.

[0040] The support mechanism 100 includes a base 101, a support frame 102 is provided on the top of the base 101, a detection member 103 is provided on the top of the support frame 102, and a detection rod 104 is provided on the bottom of the detection member 103; the protective component 205 includes a first rotation groove 205a opened on the surface of the filter plate 204, a pull rod 205b is provided on the surface of the first rotation groove 205a, and a pull plate 205c is fixedly connected to the right side of the pull rod 205b. There are extrusion grooves 205d on the upper and lower sides, and an extrusion ring 205e is provided on the surface of the extrusion groove 205d. The bottom of the detection rod 104 passes through the bottom of the extrusion ring 205e, and a groove 205f is provided on the inner wall of the support frame 102 at the top of the extrusion ring 205e. An extrusion spring 205g is provided on the surface of the groove 205f. The bottom of the extrusion spring 205g is fixedly connected to the top of the extrusion ring 205e, and a wiper 205h is provided on the top of the pulling plate 205c.

[0041] Specifically, a clearance fit is adopted between the pulling rod 205b and the first rotating groove 205a, which can not only ensure that the pulling rod 205b can rotate flexibly in the first rotating groove 205a, but also ensure that the pulling rod 205b can reliably transmit power when the filter plate 204 moves; thereby, when the filter plate 204 moves to the left, it can drive the pulling rod 205b and the pulling plate 205c to move to the left, and use the wiping piece 205h to wipe and clean its detection piece 103, thereby ensuring the detection effect.

[0042] Furthermore, as the dust is continuously inhaled and filtered, the filter plate 204 will gradually be clogged with dust. At this time, the protection and cleaning mechanism of the device is automatically activated. When the filter plate 204 is clogged and the dust concentration changes, the filter plate 204 moves to the left on the inner wall of the dust suction pipe 201 under the dual effects of dust accumulation and suction airflow. When the filter plate 204 moves, the pulling rod 205b is driven by the first rotating groove 205a, and the pulling rod 205b pulls the pulling plate 205c, and the extrusion rings in the extrusion groove 205d on the upper and lower sides of the pulling plate 205c are squeezed. Under the action of the extrusion spring 205g, 205e causes the detection rod 104 to retract into the interior of the groove 205f, thereby protecting the detection rod 104. At the same time, the wiping piece 205h on the top of the pulling plate 205c cleans and wipes the detection rod 104 when the pulling rod 205b is pulled, thereby ensuring the detection accuracy of the detection rod 104. When the filter plate 204 moves to the left, it will also drive the cleaning rod 207a to move up and down in the lifting slot 206, and the cleaning rod 207a cleans the dust attached to the surface of the filter plate 204.

[0043] It should be noted that the suction pipe 202a is made of a telescopic material, so that the filter plate 204 can move left and right.

A fixing ring 213b is disposed on the left side of the impeller 213a. A first toothed disc 213c is fixedly connected to the outer side of the fixing ring 213b. The left side of the first toothed disc 213c is fixedly connected to the right side of the discharge pipe 202e. A transmission component 214 is disposed on the surface of the first toothed disc 213c. The transmission component 214 includes a first gear 214a meshed with the surface of the first toothed disc 213c, a fixing rod 214b is provided on the right side of the first gear 214a, a connecting rod 214c is sleeved on the outer side of the fixing rod 214b, a second gear 214d is provided on the right side of the connecting rod 214c, and a second toothed disc 214e is meshed with the surface of the second gear 214d, and the right side of the second toothed disc 214e is connected to the left side of the filter plate 204; The surface of the fixed rod 214b is provided with a travel groove 215, the inner wall of the travel groove 215 is provided with a travel block 216, and the top of the travel block 216 is fixedly connected to the inner wall of the connecting rod 214c; the inner wall of the support frame 102 is provided with a sleeve rod 301, the inner wall of the sleeve rod 301 is slidably connected to the insertion rod 302, the outer surface of the insertion rod 302 is provided with an annular groove 303, the inner wall of the annular groove 303 is provided with a limiting block 304, and the top of the limiting block 304 is fixedly connected to the inner wall of the sleeve rod 301; the connecting rod 214c and the insertion rod 301 are provided with a sleeve rod 301. 02 is rotatably connected to the outer side of the connecting ring 305, and the inner wall of the connecting ring 305 is provided with an electric push rod 306. The output end of the electric push rod 306 contacts the outer side of the limiting ring 307, and the inner wall of the limiting ring 307 is fixedly connected to the outer side of the insertion rod 302. The right side of the insertion rod 302 is fixedly connected to the left side of the rotating disk 211; a second rotating groove 308 is provided on the left side of the second toothed disk 214e, and a limiting vertical rod 309 is provided on the surface of the second rotating groove 308. The bottom of the limiting vertical rod 309 is fixedly connected to the top of the connecting ring 305.

[0046] Specifically, when detecting dry dust, the output end of the electric push rod 306 is in contact with the inner wall of the limiting ring 307, so that when the filter plate 204 is blocked, it can synchronously drive the insertion rod 302 and others to move to the left; conversely, when detecting dust with moisture, the output end of the electric push rod 306 is separated from the inner wall of the limiting ring 307, so that the second nozzle 208e can directly act on the dust that is blocked and adhered to the surface of the filter plate 204.

[0047] Furthermore, when dry dust is inhaled, after the dry dust enters the dust suction pipe 201, it will first be filtered by the filter plate 204. After the dry dust is inhaled into the filter plate 204 and becomes clogged, the suction pipe 202a will be driven to move leftward on the inner wall of the dust suction pipe 201. In the process of the filter plate 204 moving leftward, the connecting ring 305 will drive the connecting rod 214c and the insertion rod 302 to move leftward. In the process of the insertion rod 302 moving leftward, the annular groove 303 will contact the limiting block 304 and be limited. The restriction of the block 304 causes the rod 302 to rotate along the stroke of the annular groove 303. During the rotation of the rod 302, the rotating disk 211 is driven to rotate, so that the rotating disk 211 drives the rotating rod 212 to rotate, and the rotating rod 212 is set at a height on the surface of the rotating disk 211, so that the rotating rod 212 drives the cleaning rod 207a to move up and down on the surface of the filter plate 204. The guide groove 207b on the front side of the cleaning rod 207a guides the dust to move along a specific path. The dust is prevented from accumulating randomly in the dust suction pipe 201, and the dust is discharged through the outlet groove 207c on the right side of the cleaning rod 207a. When the cleaning rod 207a moves to the left, the pressing block 207d is used to press the pressure rod 208a downward, so that the pressure rod 208a pushes the pressure ring 208b downward to press the water flow, thereby achieving efficient cleaning and dust reduction of dry dust, so as to meet the need for enhanced cleaning due to dust blockage; if the dust sucked in is moist, it is first controlled by the electric The movable push rod 306 causes the output end to leave the surface of the limiting ring 307. After the moist dust enters the dust suction pipe 201, the filter plate 204 will gradually move to the left after being blocked. Since the output end of the electric push rod 306 leaves the surface of the limiting ring 307, the insertion rod 302 no longer moves to the left. After the filter plate 204 is blocked and moves to the maximum stroke, the second nozzle 208e on the inner wall of the support frame 102 is started, and the second nozzle 208e directly sprays water into the dust suction pipe 201 to flush and clean the moist dust.

[0048] It should be noted that a retractable collection box is provided inside the support frame 102 to facilitate the collection and treatment of discharged dust; the first nozzle 208c adopts a retractable nozzle, and the water outlet ends of the first nozzle 208c and the second nozzle 208e are both provided with a one-way valve.

[0049] The remaining structures are the same as those of Example 2.

[0050] Example 4 Reference Figures 1 to 11 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a dust detection device for coal mine environmental safety.

[0051] When using the dust detection device; First, start the dust suction pump 202b. Under the suction force of the dust suction pump 202b, the dust in the coal mine environment is sucked into the device through the dust suction pipe 201. The sucked dust moves with the air flow and passes through the filter plate 204. The filter plate 204 intercepts the dust. The air after preliminary filtration continues to flow through the suction pipe 202a and the discharge pipe 202e to the output component 213. The impeller 213a on the left side of the discharge pipe 202e starts to rotate under the push of the exhaust air flow. The impeller 213a drives the fixed ring 213b and the first toothed disc 213c on the outside to rotate synchronously. The first toothed disc 213c passes through the filter plate 204. The power is transmitted to the second gear 214d on the right side through the meshing first gear 214a, the fixed rod 214b, and the connecting rod 214c sleeved on the fixed rod 214b. The second gear 214d meshes with the second toothed disc 214e, thereby driving the second toothed disc 214e to rotate, thereby achieving stable transmission and treatment of dust in the device. During the dust inhalation process, the detection element 103 detects the concentration of the inhaled dust in real time through the detection rod 104, and feeds the data back to the control system, providing a basis for the coal mine environmental safety assessment. The device adopts different treatment methods for dust with different characteristics. When dry dust is sucked in, after the dry dust enters the dust suction pipe 201, it will first be filtered by the filter plate 204. After the dry dust is sucked in and the filter plate 204 is clogged, it will drive the suction pipe 202a to move leftward on the inner wall of the dust suction pipe 201. In the process of the filter plate 204 moving to the left, the connecting ring 305 will drive the connecting rod 214c and the insertion rod 302 to move leftward. In the process of the insertion rod 302 moving to the left, the annular groove 303 will contact the limiting block 304 and be restricted by the limiting block 304, so that the insertion rod 302 will rotate along the stroke of the annular groove 303. In the process of the rotation of the insertion rod 302, the rotating disk 211 will be driven to rotate, so that the rotating disk 211 drives the rotating rod 212 to rotate, and through Due to the height of the rotating rod 212 on the surface of the rotating disk 211, the rotating rod 212 drives the cleaning rod 207a to move up and down on the surface of the filter plate 204. The guide groove 207b on the front side of the cleaning rod 207a guides the dust to move along a specific path, thereby preventing the dust from accumulating randomly in the dust suction pipe 201. At the same time, the dust is discharged through the guide groove 207c on the right side of the cleaning rod 207a. In the process of the cleaning rod 207a moving to the left, the pressing block 207d is used to squeeze the pressure rod 208a downward, so that the pressure rod 208a pushes the pressure ring 208b downward to pressurize the water flow, thereby achieving efficient cleaning and dust reduction of dry dust, so as to meet the need for enhanced cleaning due to dust blockage; If the dust inhaled is moist, the electric push rod 306 is first controlled to make the output end leave the surface of the restriction ring 307. After the moist dust enters the dust suction pipe 201, the filter plate 204 will gradually move to the left after being blocked. Since the output end of the electric push rod 306 leaves the surface of the restriction ring 307, the insertion rod 302 no longer moves to the left. After the filter plate 204 is blocked and moves to the maximum stroke, the second nozzle 208e on the inner wall of the support frame 102 is activated, and the second nozzle 208e directly sprays water into the dust suction pipe 201 to flush and clean the moist dust. As the dust is continuously inhaled and filtered, the filter plate 204 will gradually be clogged with dust. At this time, the protection and cleaning mechanism of the device is automatically activated. When the filter plate 204 is clogged and the dust concentration changes, the filter plate 204 moves to the left on the inner wall of the dust suction pipe 201 under the dual effects of dust accumulation and suction airflow. When the filter plate 204 moves, the pulling rod 205b is driven by the first rotating groove 205a, and the pulling rod 205b pulls the pulling plate 205c. The upper and lower sides of the pulling plate 205c squeeze the extrusion rings 205 in the groove 205d. e Under the action of the extrusion spring 205g, the detection rod 104 retracts into the interior of the groove 205f, which protects the detection rod 104. At the same time, the wiping piece 205h on the top of the pulling plate 205c cleans and wipes the detection rod 104 when the pulling rod 205b is pulled, ensuring the detection accuracy of the detection rod 104. When the filter plate 204 moves to the left, it will also drive the cleaning rod 207a to move up and down in the lifting slot 206, and the cleaning rod 207a cleans the dust attached to the surface of the filter plate 204.

[0052] In summary: when detecting dry dust, the cleaning rod 207a can be used for cleaning by cleaning guidance; when detecting dust with moisture, the second nozzle 208e can be used for direct spraying; the initial position of the filter plate 204 is on the right side of the inner wall of the lifting groove 206.
