Description

TECHNICAL FIELD

[0001] The present application relates to the field of mine safety equipment production, in particular to a mine blasting anti-misoperation intelligent locking device. BACKGROUND

[0002] Mine blasting is a key technical link in the process of mineral resources exploitation, which can efficiently break up ore and rock, thereby facilitating subsequent mining, transportation and other operations. With the continuous development of mining industry, mine blasting technology is also continuously progressing. In remote detonation operation, wireless radio signals or other electronic signals are usually used to trigger the detonation device. However, due to the operator's mistake, such as misoperation of the detonation button or incorrect setting of the detonation parameters, misoperation accidents occur, which may cause danger. Therefore, it is necessary to design a mine blasting anti-misoperation intelligent locking device.

[0003] After searching, the patent with patent number CN216845921U is found, which is named as a mine blasting detonation device with anti-misoperation structure, which comprises: a machine body, the outer surface of the machine body is provided with a working cover, the top end of the working cover is fixedly installed with a signal rod, and the outer surface of the working cover is installed with a control knob. The technical solution is to protect the control knob by the protection structure of the first and second extension plates. However, in actual operation, when the control knob needs to be frequently used, the operation process will become cumbersome. Specifically, every time the control knob needs to be operated, the second extension plate needs to be first disconnected from the mounting plate, and then the extension plate needs to be retracted. This series of actions will increase the operation time and difficulty, especially in emergency situations, which will affect the timeliness of the blasting operation. Moreover, in the mine blasting environment, there are a large number of ore particles, dust and other impurities. Since there is a gap between the first and second extension plates and the control knob during the extension process, these ore particles and impurities can easily enter the surface of the control knob under the action of gravity and equipment vibration. With the passage of time, the ore particles and impurities will accumulate more and more in the gap. When the first and second extension plates are extended, they will squeeze the accumulated ore particles and impurities in the gap. Since the distance between the extension plate and the control knob is relatively close, the squeezed ore particles and impurities will generate pressure. During the extension process of the first and second extension plates, the pressure will be transmitted to the control knob, thereby causing misoperation and posing a direct threat to the safety of personnel on site.

[0004] Therefore, it is necessary to propose a mine blasting anti-misoperation intelligent locking device to solve the above technical problems. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides an intelligent anti-misfire locking device for mine blasting, which solves the technical problems of increasing operation time and difficulty, affecting the timeliness of blasting and the gap between the telescopic plate and the control knob, and impurities easily entering the surface of the control knob and accumulating by operating the control knob each time, and then unfastening the fastening connection of the second telescopic plate on the mounting plate and then retracting the telescopic plate.

[0030] The present invention has achieved the following beneficial effects:

[0031] (1) By setting up an emergency unlocking component, the present invention eliminates the need for cumbersome operations such as unfastening and retracting the telescopic plate. Simply moving the locking plate can quickly achieve locking and unlocking to prevent accidental explosion, greatly reducing operation time and difficulty and improving work efficiency. Especially in emergency situations, it can carry out blasting operations more quickly, ensuring the timeliness of the operation. The present invention forms a dual anti-accidental explosion protection mechanism by locking the button key to prevent accidental touch and automatically cutting off the power supply of the cable joint through the emergency unlocking component. Even in extreme cases where the anti-accidental plate malfunctions or is accidentally damaged, as long as the unlocking plate is in the locked position, the power supply is still cut off, greatly reducing the probability of accidental explosion and providing more reliable safety protection for mine blasting operations.

[0032] (2) By setting up a dust removal component, the present invention can effectively clean the dust and mineral particles on the surface of the button key through multiple methods. The isolation plate is U-shaped and cooperates with the base plate to prevent dust from entering the area around the button key. At the same time, it is connected to the discharge groove of the anti-misoperation plate to discharge dust. The soft brush can contact the surface of the button key for friction cleaning when the anti-misoperation plate moves. When the anti-misoperation plate is opened, gas will also be sprayed out from the first and second spray grooves of the isolation plate to blow and clean the button key and its surroundings. The combination of multiple cleaning methods can more comprehensively remove any impurities that may exist around the button key, keep the button key and its surrounding environment clean, and reduce the probability of accidental touches caused by dust accumulation.

[0033] (3) By using the screw, turntable, rotating block, pull rod and other structures above the anti-misoperation plate, the soft brush can be extended and retracted by pulling the pull rod. This allows for precise adjustment of the extension and retraction of the soft brush according to the actual situation of dust on the button surface (such as the amount of dust, the degree of stubbornness, etc.), achieving targeted cleaning. This effectively removes dust and mineral particles, avoids unnecessary wear on the button surface due to excessive cleaning, extends the service life of the button, and ensures that it always maintains a good working condition.

[0049] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0050] like Figures 1-5As shown, an intelligent interlocking device for preventing accidental detonation in mine blasting includes a detonator 1, a button 12 located below the detonator 1, an interface 13 located at the bottom of the detonator 1, a cable connector 14 located at the bottom of the interface 13, and an emergency unlocking component 2, which is mounted on the detonator 1 and used to perform an anti-accidental detonation operation on the button 12 when the detonator 1 is not in use. The component includes: an anti-accidental detonation plate 21, which has a concave shape and is located below the detonator 1 to cover the button 12; at least two slide rails 22, installed at the left and right ends of the detonator 1, with a through hole in the middle of the slide rail 22; at least two first reset spring rods 23, vertically installed in the through hole; and at least two sliders 24, slidably connected to the slide rail. The rail 22 is located away from the detonator 1 at one end, and its top end is slidably connected to the first reset spring rod 23; the base plate 25 is elongated and is inserted into the bottom of the detonator 1, with a vertically arranged linkage groove on the top of the base plate 25, and the cable connector 14 is installed in the middle of the base plate 25; the unlocking plate 26 is installed below the slider 24, with an angled opening on one side of its lower end, and an insertion port on the lower rear side of the unlocking plate 26, with the end of the unlocking plate 26 away from the slider 24 sliding through the top of the base plate 25; the second reset spring rod 27 is installed on the bottom wall of the linkage groove in the base plate 25; the latch plate 28 has an angled opening on its top, which is slidably connected to the moving end of the second reset spring rod 27, and the top end of the latch plate 28 is inserted into the insertion port of the unlocking plate 26.

[0051] When an anti-accidental detonation operation is required, the first reset spring rod 23 is released. Under the elastic force of the first reset spring rod 23, it drives the slider 24 to slide along the slide rail 22 towards the direction below the detonator 1, thereby completely blocking the button 12 to prevent accidental activation. At the same time, when the unlocking plate 26 moves with the slider 24 and passes through the interior of the base plate 25, the angled end of the unlocking plate 26 will abut against the angled opening on the latch plate 28. As the unlocking plate 26 continues to move, it will cause the latch plate 28 to be squeezed under the second reset spring rod 27, causing the second reset spring rod 27 to enter a compressed state. When the unlocking plate 26 is completely inside the base plate 25, under the elastic force of the second reset spring rod 27, the top of the latch plate 28 will insert into the slot on the rear side below the unlocking plate 26, thereby completing the rapid locking of the anti-accidental detonation plate 21 and ensuring that the anti-accidental detonation plate 21 is stably blocked outside the button 12, effectively preventing accidental detonation.

[0052] When it is necessary to quickly open the anti-accidental explosion protection for blasting operations, the operator only needs to move the locking plate 28 downward along the linkage groove so that its top end disengages from the socket of the unlocking plate 26. At this time, the spring potential energy of the first reset spring rod 23 is released, which drives the slider 24 to slide along the slide rail 22 away from the detonator 1, thereby driving the anti-accidental explosion protection plate 21 to move away quickly, exposing the button 12, so that the operator can quickly operate the button 12, thereby improving the timeliness of operation and being able to better deal with emergencies.

[0053] When the control button needs to be used frequently, the intelligent locking device of the present invention eliminates the need for cumbersome operations such as unfastening and fastening connections and retracting telescopic plates. Simply moving the locking plate 28 can quickly achieve locking and unlocking to prevent accidental explosions, greatly reducing operation time and difficulty and improving work efficiency. Especially in emergency situations, it can carry out blasting operations more quickly, ensuring the timeliness of the operation.

[0054] like Figures 4-5 As shown, the emergency unlocking component 2 also includes a concave plate 291. A movable groove 29 communicating with the linkage groove is provided below the base plate 25. The concave plate 291 is slidably connected inside the movable groove 29. The concave plate 291 is fixedly connected to the end of the latch plate 28 away from the slider 24. A rubber pad is installed on the inner side of the concave plate 291. When it is necessary to quickly open the anti-explosion device, the operator inserts his finger into the groove of the concave plate 291. Since a rubber pad is installed on the inner side of the concave plate 291, when the finger contacts the rubber pad, the rubber pad can increase the friction, making it easier for the operator to apply force and improving the convenience of the unlocking operation.

[0055] Neither of the two vertical ends of the concave plate 291 protrudes outside the moving groove 29. This design can prevent the concave plate 291 from sliding due to accidental collision or friction of external objects. The concave plate 291 will only slide in the moving groove 29 when the operator intentionally inserts his finger into the groove of the concave plate 291 and applies sufficient inward pushing force. This effectively avoids the risk of accidental locking and possible accidental explosion caused by accidental situations.

[0056] like Figure 4 , Figure 6 and Figure 7As shown, the cable connector 14 has a connector groove 211 inside, and a connector corrugated tube 212 is installed inside the connector groove 211. A connector head 213 that is slidably connected to the inside of the base plate 25 is installed at the end of the connector corrugated tube 212 away from the cable connector 14. The connector head 213 and the cable connector 14 are electrically connected. The connector head 213 is inserted into the interface 13. An expansion spring 214 is installed inside the connector groove 211. Connecting blocks 215 that are slidably connected to the inside of the base plate 25 are installed at the left and right ends of the connector head 213. The connecting blocks 215 have an L-shaped structure. A drive plate 216 is installed at the vertical end of the connecting block 215. The top of the drive plate 216 has a triangular structure. The angle of the unlocking plate 26 is close to the angle of the drive plate 216.

[0057] It should be noted that when the anti-accidental detonation operation is performed and the unlocking plate 26 is inserted into the base plate 25, the angle of the unlocking plate 26 is in close contact with the inclined surface of the drive plate 216. As the unlocking plate 26 continues to be inserted, due to the interaction of the inclined surfaces, the unlocking plate 26 will exert an outward (away from the detonator 1) pushing force on the drive plates 216 on both sides. The drive plate 216 drives the connecting block 215 to move outward. The movement of the connecting block 215 will cause the connector 213 to disengage from the interface 13. During this process, the expansion spring 214 installed inside the connector groove 211 is compressed. After the connector 213 disengages from the interface 13, the power connection between the cable connector 14 and the detonator 1 is successfully cut off. Even if the button 12 is accidentally pressed, the explosive cannot be detonated because the power has been cut off, thereby greatly improving the safety of preventing accidental detonation.

[0058] When unlocking is required for normal blasting operations, the unlocking plate 26 disengages from the bottom plate 25. At this time, the expansion spring 214 is no longer restricted by the compression of the unlocking plate 26, and its spring potential energy is released. The expansion spring 214 will push the connector 213 to move inward along the interface 13. The connector 213 is re-inserted into the interface 13 to achieve plugging, thereby restoring the connection between the cable connector 14 and the interface 13, providing power support for the normal operation of the detonator 1, and enabling the blasting operation to proceed smoothly.

[0059] This invention forms a dual anti-accidental explosion protection mechanism by locking the button 12 to prevent accidental touches and automatically cutting off the power supply to the cable connector 14 through the emergency unlocking component 2. Even in extreme cases where the anti-accidental explosion plate 21 malfunctions or is accidentally damaged, as long as the unlocking plate 26 is in the locked position, the power supply remains cut off, greatly reducing the probability of accidental explosion and providing more reliable safety protection for mine blasting operations.

[0060] It is worth noting that the connector 213 will slide inside the base plate 25 under different operating scenarios (such as the disengagement action during the anti-explosion operation and the re-insertion action during the unlocking operation), and its position will change. Therefore, the connector bellows 212 is provided with a telescopic function so that it can closely follow the movement of the connector 213 and correspondingly expand and contract.

[0061] like Figure 6 As shown, a ring-shaped limiting groove 217 is provided on the inner side of the base plate 25, and a limiting ring 218 is installed at the bottom end of the connector 213. The limiting ring 218 is slidably connected inside the limiting groove 217.

[0062] It should be noted that during the unlocking and power restoration process, the limiting ring 218 at the bottom of the connector 213 slides within the limiting groove 217 on the inner side of the base plate 25. When the expansion spring 214 pushes the connector 213 to move, the limiting ring 218 is restricted by the limiting groove 217 to prevent excessive movement of the connector 213 from damaging the interface 13 and to ensure the normal use of the interface 13.

[0063] like Figure 6 As shown, multiple ring-shaped damping rods 219 are installed in the limiting groove 217. One end of the damping rod 219 slides through the inner side of the limiting ring 218. By controlling the moving speed of the connector 213 through the damping rod 219, the risk of damage to the connector 213 and the interface 13 due to excessive impact force during the insertion process can be further reduced.

[0064] like Figure 2 , Figure 8 and Figure 9 As shown, the dust removal component 3 is installed on the detonator 1 and is used to clean the dust and ore particles on the surface of the button 12 in a timely manner. The dust removal component 3 includes an isolation plate 31, which has an inverted U-shaped structure and two inclined openings at the two vertical ends of the isolation plate 31; a soft brush 32, which is installed below the anti-misoperation plate 21; a triangular plate 33, which is installed below the detonator 1; and discharge grooves 34 are opened at the left and right ends of the anti-misoperation plate 21. The gap between the two vertical ends of the isolation plate 31 and the inclined surface of the triangular plate 33 forms a channel, which is connected to the discharge groove 34.

[0065] It should be noted that the isolation plate 31, with its inverted U-shaped structure, works in conjunction with the base plate 25 to enclose the button 12 in its center, forming a relatively enclosed space. This structural design makes it difficult for dust and mineral particles to penetrate from the top and bottom ends of the button 12 into its vicinity. Because the two vertical ends of the isolation plate 31 are inclined, and there is a gap between the two vertical ends of the isolation plate 31 and the inclined surface of the triangular plate 33, forming a channel, this channel connects to the discharge slots 34 on the left and right ends of the anti-misoperation plate 21. This reduces the contamination of the button 12 by external dust and mineral particles and allows for the removal of dust from the button 12. Specifically, when the button 12 needs to be operated and the anti-misoperation plate 21 slides upward, the soft brush 32 located below the anti-misoperation plate 21 will come into contact with the surface of the button 12 as the anti-misoperation plate 21 moves. Through friction with the surface of the button 12, the soft brush 32 can brush up and clean the dust adhering to the surface of the button 12. The dust stirred up by the brush will be guided by the channel formed by the isolation plate 31, the triangular plate 33 and the discharge groove 34, and discharged from the discharge groove 34. This achieves timely cleaning of the dust on the surface of the button 12 and discharges the cleaned dust outside the device, keeping the environment around the button 12 relatively clean and reducing the possibility of accidental touches due to dust accumulation. Through the protection of the isolation plate 31 and the cleaning action of the soft brush 32, the dust and mineral particles on the surface of the button 12 can be effectively removed, keeping it in a relatively clean state at all times.

[0066] like Figure 1 , Figure 8 and Figure 10 As shown, the anti-misoperation plate 21 is located above the soft brush 32 and is threadedly connected to a lead screw 311. A turntable 312 is installed at the end of the lead screw 311 away from the soft brush 32. Limiting support frames that slide through one side of the anti-misoperation plate 21 are installed at the left and right ends of the soft brush 32. A limiting seat 313 is installed at the front end of the anti-misoperation plate 21. The limiting seat 313 is formed by an arc shape and a horizontal shape. A rotating block 314 is connected to one side of the turntable 312 through a slide rail 22. The rotating block 314 has an L-shaped structure. A T-slot is opened on the side of the arc shape of the limiting seat 313 away from the anti-misoperation plate 21. The end of the rotating block 314 away from the connector 213 slides through the T-slot. An auxiliary rod 315 is rotatably connected to the middle of the horizontal end of the limiting seat 313. The moving end of the auxiliary rod 315 is rotatably connected to the horizontal end of the rotating block 314. A pull rod 316 is installed on the side wall of the horizontal end of the rotating block 314.

[0067] Pulling the lever 316 causes the L-shaped rotating block 314 to slide within the T-groove of the arc-shaped portion of the limiting seat 313, changing the angle and position of the rotating block 314. The rotating block 314 is connected to the turntable 312 via the slide rail 22. When the rotating block 314 rotates, it drives the turntable 312 to rotate via the slide rail 22. The rotation of the turntable 312 then drives the lead screw 311 to rotate. When the lead screw 311 rotates on the anti-misoperation plate 21, it undergoes a telescopic movement due to its connection with the soft brush 32 through the limiting support frame, thereby causing the soft brush 32 to extend and retract. When the lead screw 311 extends, the soft brush 32 extends backward; when it retracts, the soft brush 32 retracts forward. The extension and retraction of the soft brush 32 can be precisely adjusted according to the actual situation of dust on the surface of the button 12, such as the amount and stubbornness of the dust, to achieve targeted cleaning.

[0068] It is worth noting that the auxiliary rod 315 can extend and retract, which can better adapt to the rotational changes of the rotating block 314 and can play a role in buffering stress.

[0069] like Figure 9 and Figure 11 As shown, two sleeves 321 are installed at the rear end of the detonator 1. A drive block 322 is installed at the lower end of the two anti-misoperation plates 21 away from the detonator 1. A drive rod 323 is installed on the top of the drive block 322 and is slidably connected to the inner side of the sleeve 321. A pipe 324 is installed at the end of the sleeve 321 away from the first reset spring rod 23. The end of the pipe 324 away from the sleeve 321 slides through the anti-misoperation plate 21 and is fixedly connected to the isolation plate 31. Multiple first spray grooves 325 are opened at the horizontal end of the isolation plate 31. The first spray grooves 325 are connected to the pipe 324. Second spray grooves 326 are opened on opposite sides of the two vertical ends of the isolation plate 31 and are connected to the pipe 324. The second spray grooves 326 are arranged obliquely along the direction of the button 12 on the inner side of the isolation plate 31.

[0070] It should be noted that when the anti-misoperation plate 21 is opened, the slider 24 connected to it will move upward. Since the slider 24 is connected to the drive block 322, the upward movement of the slider 24 will drive the drive block 322 to move together. There is a certain amount of gas in the sleeve 321. When the drive rod 323 slides in the sleeve 321, it will squeeze the gas in the sleeve 321, so that the gas is transmitted through the pipe 324 under pressure. The gas can smoothly enter the pipe 324 and flow towards the isolation plate 31. After passing through the pipe 324, the gas will be sprayed out from the multiple first spray grooves 325 and second spray grooves 326 opened on the isolation plate 31 respectively.

[0071] The first spray groove 325 is located at the horizontal end of the isolation plate 31. The sprayed gas can directly act on the surface of the button key 12 and its surrounding area to blow away any residual dust, mineral particles and other impurities. The second spray groove 326 is located on the opposite sides of the two vertical ends of the isolation plate 31 and is arranged at an angle along the direction of the button key 12. This arrangement allows the gas sprayed from the second spray groove 326 to be blown onto the surface of the button key 12 at a certain angle, forming a multi-angle blowing effect. This further enhances the cleaning effect on the surface of the button key 12 and the corners and other parts that are difficult to clean, thereby more comprehensively removing any impurities that may exist around the button key 12, keeping the button key 12 and its surrounding environment clean, and reducing the probability of accidental touches caused by the accumulation of impurities.

[0072] like Figure 12 As shown, ear seats 241 are installed at both ends of the top of the slider 24. The top of the anti-mistake plate 21 is rotatably connected in the ear seats 241 through a rotating shaft. Magnets are installed on the two vertical ends of the anti-mistake plate 21. A magnetic strip that attracts the magnet is installed on the end of the slider 24 near the anti-mistake plate 21.

[0073] It should be noted that this design allows the anti-misoperation plate 21 to rotate around the pivot within the ear seat 241. Simultaneously, the magnets mounted on the two vertical ends of the anti-misoperation plate 21 attract each other to the magnetic strip mounted on the end of the slider 24 near the anti-misoperation plate 21. This magnetic force assists in fixing and positioning, ensuring that the anti-misoperation plate 21 remains relatively stable on the slider 24 under normal conditions, while also allowing it to rotate smoothly around the pivot within the ear seat 241 under a certain external force. When it is necessary to replace the soft brush 32 or perform fine finishing on the surface of the button 12, the operator can apply appropriate external force to overcome the attraction between the magnets and the magnetic strip, allowing the anti-misoperation plate 21 to rotate around the pivot within the ear seat 241. This rotating connection design greatly improves the convenience of replacing the soft brush 32 and fine finishing the surface of the button 12.

[0074] It is worth noting that, such as Figure 13 As shown, an intelligent electric actuator is installed in the middle of the rear end of the detonator 1. The moving end of the intelligent electric actuator is fixedly connected to the middle of the drive block 322. The device is equipped with a high-precision gas sensor and a dust sensor to monitor environmental parameters such as gas concentration and dust content at the blasting site in real time. When the gas concentration exceeds the set threshold or the dust content reaches a dangerous level, the system will drive the anti-misfire plate 21 to reset through the intelligent electric actuator, cut off the power supply of the detonator, and thus prevent accidental detonation.

[0075] The working principle of this invention is that the intelligent interlocking device for preventing accidental explosions in mine blasting, when in use:

[0076] Locking process: The first reset spring rod 23 is released, and the slider 24 slides along the slide rail 22 downwards from the detonator 1 under the action of the spring force, and the anti-misoperation plate 21 blocks the button 12. At the same time, the unlocking plate 26 moves with the slider 24, and its angle abuts against the angled opening of the locking plate 28, pushing the locking plate 28 to compress the second reset spring rod 27. When the unlocking plate 26 is fully inserted into the base plate 25, the locking plate 28 is inserted into its socket, locking the anti-misoperation plate 21.

[0077] Unlocking process: The locking plate 28 is moved down along the linkage groove so that its top end is disengaged from the socket. The first reset spring rod 23 releases potential energy, and the slider 24 drives the anti-misoperation plate 21 to move away, exposing the button 12. The concave plate 291 is connected to the locking plate 28. The rubber pad on its inner side increases the friction to facilitate unlocking, and the vertical end of the concave plate 291 is in the moving groove 29 to prevent accidental sliding unlocking.

[0078] Cable connector 14 power control: During the anti-explosion operation, the unlocking plate 26 is inserted into the base plate 25, and its angle contacts the inclined surface of the drive plate 216, pushing the drive plate 216 to move the connecting block 215 outward, and the connector 213 is disengaged from the interface 13, compressing the expansion spring 214 to achieve the purpose of cutting off the power supply. When unlocking, the unlocking plate 26 is disengaged, and the expansion spring 214 pushes the connector 213 to insert into the interface 13 to restore the connection.

[0079] Dust removal component 3: The isolation plate 31 is U-shaped and cooperates with the base plate 25 to surround the button 12. Its vertical end is inclined to open a channel that communicates with the discharge groove 34 of the anti-misoperation plate 21 to prevent dust from entering and also to discharge dust. When the anti-misoperation plate 21 moves, the soft brush 32 contacts the button 12 to clean the dust. Through the structure of lead screw 311, turntable 312, rotating block 314, pull rod 316, etc., pulling the pull rod 316 can make the rotating block 314 rotate. Through transmission, the lead screw 311 rotates, which drives the soft brush 32 to extend and retract, adjusting the cleaning force. When the anti-misoperation plate 21 opens, the slider 24 drives the drive block 322. The drive rod 323 slides in the sleeve 321 to compress the gas. The gas is sprayed out from the first spray groove 325 and the inclined second spray groove 326 of the isolation plate 31 through the pipe 324 to clean the button 12 and the surrounding dust.
