Description

Technical Field

[0001] The invention relates to the field of mine safety equipment production, in particular to an intelligent locking device for preventing accidental explosion in mine blasting. Background Art

[0002] Mine blasting is a key technical link in the process of mineral resource mining. It can efficiently crush ore and rock, thus facilitating subsequent mining, transportation and other operations. With the continuous development of the mining industry, mine blasting technology is also constantly improving. When performing remote detonation operations, radio signals or other electronic signals are usually used to trigger the detonator. However, the existing detonators are prone to accidental explosions due to operator errors, such as accidentally touching the detonation button, incorrectly setting the detonation parameters, etc., which causes dangers. Therefore, it is necessary to design an intelligent locking device to prevent accidental explosions for mine blasting.

[0003] After searching, the Chinese patent announcement number CN216845921U is a patent for a detonating device with an anti-misoperation structure for mine blasting, comprising: a body, a working cover is arranged on the outer surface of the body, a signal rod is fixedly installed on the top of the working cover, and a control button is installed on the outer surface of the working cover. The technical solution is to protect the control button through the protective structure of the first telescopic plate and the second telescopic plate. However, in actual operation, when the control button needs to be used frequently, the operation process becomes cumbersome. The specific operation is that each time the control button is operated, it is necessary to first unfasten the buckle connection of the second telescopic plate on the mounting plate, and then retract the telescopic plate. This series of actions will increase the operation time and difficulty, especially in an emergency situation, which will affect the timeliness of the blasting operation. Moreover, in the mine blasting environment, there are a large number of impurities such as ore particles and dust. Since there is a gap between the first telescopic plate and the second telescopic plate and the control button during the telescopic process, these ore particles and impurities can easily enter the surface of the control button under the action of gravity and equipment vibration. As time goes by, the ore particles and impurities accumulate more and more therein. When the first telescopic plate and the second telescopic plate are telescoped, they will squeeze the already gathered ore particles and impurities in the gap. Since the distance between the telescopic plate and the control button is short, these squeezed ore particles and impurity particles will generate pressure. During the telescopic process of the first telescopic plate and the second telescopic plate, the pressure will be transmitted to the control button, thereby causing accidental explosion, posing a direct threat to the life safety of the personnel on site.

[0004] Therefore, it is necessary to propose an intelligent locking device for preventing accidental explosion in mine blasting to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an intelligent locking device for preventing accidental explosions in mine blasting, which solves the problem that each time the control button is operated, it is necessary to first unfasten the snap connection between the second telescopic plate on the mounting plate and then retract the telescopic plate, which increases the operation time and difficulty and may also affect the timeliness of blasting in an emergency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 5 As shown, an intelligent locking device for preventing accidental explosion for mine blasting includes a detonator 1, a button key 12 is arranged at the bottom of the detonator 1, an interface 13 is arranged at the bottom of the detonator 1, a cable connector 14 is arranged at the bottom of the interface 13, and an emergency unlocking component 2 is arranged on the detonator 1, which is used to operate the button key 12 to prevent accidental explosion when the detonator 1 is not in use, and includes: an anti-mistaken plate 21, which is a concave structure and is arranged at the bottom of the detonator 1 to cover the button key 12; a slide rail 22, which has at least two numbers and is installed at the left and right ends of the detonator 1, and a through hole is opened in the middle of the slide rail 22; a first reset spring rod 23, which has at least two numbers and is vertically installed in the through hole; a slider 24, which has at least two numbers and is slidably connected to the slide The rail 22 is away from one end of the detonator 1, and its top end is slidably connected to the first return spring rod 23; the bottom plate 25 is of a long structure and is plugged and installed at the bottom of the detonator 1. A vertical linkage groove is provided on the top of the bottom plate 25, and the cable connector 14 is installed in the middle of the bottom plate 25; an unlocking plate 26 is installed below the slider 24, and an oblique angle is provided on one side of its lower end, and a socket is provided on the lower rear side of the unlocking plate 26, and the end of the unlocking plate 26 away from the slider 24 slides through the top of the bottom plate 25; a second return spring rod 27 is installed on the bottom wall of the linkage groove in the bottom plate 25; a locking plate 28, a bevel is provided on the top of the locking plate 28, and it is slidably connected to the moving end of the second return spring rod 27, and the top of the locking plate 28 is inserted into the socket of the unlocking plate 26.

[0023] When the accidental explosion prevention operation is required, the first return spring rod 23 is released. Under the elastic force of the first return spring rod 23, the slider 24 is driven to slide along the slide rail 22 toward the bottom of the detonator 1, thereby completely covering the button key 12 to prevent accidental touch. At the same time, when the unlocking plate 26 passes through the bottom plate 25 with the movement of one end of the slider 24, the bevel at the lower end of the unlocking plate 26 will conflict with the bevel on the locking plate 28. As the unlocking plate 26 continues to move, the locking plate 28 will be squeezed under the second return spring rod 27, so that the second return spring rod 27 enters a compressed state. When the unlocking plate 26 completely enters the bottom plate 25, the top end of the locking plate 28 is inserted into the socket on the rear side of the lower side of the unlocking plate 26 under the elastic force of the second return spring rod 27, thereby completing the rapid locking of the anti-error plate 21, ensuring that the anti-error plate 21 is firmly blocked outside the button key 12, effectively preventing accidental explosion. When it is necessary to quickly open the anti-misfire plate 28 for blasting operation, the operator only needs to move the lock plate 28 downward along the linkage groove to disengage the top end of the lock plate 28 from the socket of the unlocking plate 26. At this time, the spring potential energy of the first reset spring rod 23 is released, driving the slider 24 to slide along the slide rail 22 away from the detonator 1, thereby driving the anti-misfire 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 the operation and being able to better respond to emergency situations. The intelligent locking device of the present invention does not need to perform cumbersome operations such as unfastening and retracting the telescopic plate when the control button needs to be used frequently. It only needs to simply move the locking plate 28 to quickly achieve locking and unlocking to prevent accidental explosion, which greatly reduces the operation time and difficulty and improves work efficiency. Especially in emergency situations, blasting operations can be carried out more quickly, ensuring the timeliness of the operation.

[0024] like Figure 4-Figure 5 As shown, the emergency unlocking assembly 2 also includes a concave plate 291. A moving groove 29 connected to the linkage groove is provided below the bottom plate 25. The concave plate 291 is slidably connected inside the moving groove 29. The concave plate 291 is fixedly connected to the end of the lock plate 28 away from the slider 24. A rubber pad is installed on the inner side of the concave plate 291. When the accidental explosion prevention device needs to be opened quickly, the operator inserts a finger into the groove of the concave plate 291. Since the 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 force, making it easier for the operator to apply force, thereby improving the convenience of the unlocking operation. Both vertical ends of the concave plate 291 do not extend out of the moving groove 29. This design can prevent the concave plate 291 from accidentally colliding or rubbing against the concave plate 291 by external objects and causing it to slide. Only when the operator intentionally inserts his finger into the groove of the concave plate 291 and applies sufficient inward pushing force, the concave plate 291 will slide in the moving groove 29, thereby effectively avoiding the risk of mis-locking and possible mis-explosion caused by unexpected situations. like Figure 4 , Figure 6 and Figure 7 As shown, a connector groove 211 is provided inside the cable connector 14, a connector bellows 212 is installed inside the connector groove 211, a connector head 213 slidably connected to the inner side of the bottom plate 25 is installed at one end of the connector bellows 212 away from the cable connector 14, the connector head 213 and the cable connector 14 are electrically connected, the connector head 213 is plugged into the interface 13, an expansion spring 214 is installed inside the connector groove 211, and connecting blocks 215 slidably connected in the bottom plate 25 are installed at the left and right ends of the connector head 213, the connecting block 215 is in an L-shaped structure, a driving plate 216 is installed at the vertical end of the connecting block 215, the top of the driving plate 216 is in a triangular structure, and the bevel of the unlocking plate 26 is tightly attached to the bevel of the driving plate 216.

[0025] It should be noted that when the unlocking plate 26 is inserted into the bottom plate 25 to prevent accidental explosion, the bevel of the unlocking plate 26 is in close contact with the bevel of the driving plate 216. As the unlocking plate 26 continues to be inserted, due to the interaction of the bevels, the unlocking plate 26 will apply an outward thrust (away from the detonator 1) to the driving plates 216 on both sides, and the driving plate 216 drives the connecting block 215 to move outward. The movement of the connecting block 215 drives the connector 213 to disengage from the inside of the interface 13. In this process, the expansion spring 214 installed in the connector groove 211 is compressed. After the connector 213 is disengaged 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 touched, the explosive cannot be detonated because the power has been cut off, thereby greatly improving the safety of preventing accidental explosion. When unlocking is required for normal blasting operation, the unlocking plate 26 is separated from the bottom plate 25. At this time, the expansion spring 214 is no longer restricted by the extrusion of the unlocking plate 26, and its spring potential energy is released. The expansion spring 214 pushes the connector 213 to move inward along the interface 13, and the connector 213 is reinserted 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, so that the blasting operation can proceed smoothly; The present invention forms a dual protection mechanism against accidental explosion by means of the anti-accidental-touch shielding and locking of the button key 12 by the emergency unlocking component 2 and the automatic cutting off of the power supply of the cable connector 14. Even in the extreme case that the anti-accidental-explosion plate 21 fails or is accidentally damaged, as long as the unlocking plate 26 is in the locked position, the power supply is still in the cut-off state, which greatly reduces the probability of accidental explosion and provides more reliable safety protection for mine blasting operations.

[0026] It is worth noting that the connector 213 will slide on the inside of the base plate 25 in different operating scenarios (such as the disengagement action during the anti-accidental explosion operation and the reinsertion 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 telescope and deform accordingly.

[0027] like Figure 6 As shown, a ring-shaped limiting groove 217 is opened on the inner side of the bottom plate 25 , and a limiting ring 218 is installed on the bottom end of the connector 213 , and the limiting ring 218 is slidably connected inside the limiting groove 217 .

[0028] It should be noted that, during the unlocking and power restoration process, the limiting ring 218 at the bottom end of the connector 213 is slidably connected in the limiting groove 217 on the inner side of the bottom plate 25. When the expansion spring 214 pushes the connector 213 to move, the limiting ring 218 is limited by the limiting groove 217 to prevent the connector 213 from excessively moving and damaging the interface 13, thereby ensuring the normal use of the interface 13.

[0029] like Figure 6 As shown, a plurality of ring-shaped damping rods 219 are installed in the limit groove 217. One end of the damping rod 219 slides through the inner side of the limit ring 218. By controlling the moving speed of the connector 213 by the damping rod 219, the risk of damage between the connector 213 and the interface 13 due to excessive impact force during the plug-in process can be further reduced.

[0030] like Figure 2 , Figure 8 and Fig. 9 As shown, a cleaning component 3 is arranged on the detonator 1, and is used for timely cleaning the dust and mineral particles on the surface of the button key 12. The cleaning component 3 includes an isolation plate 31, and the isolation plate 31 is an inverted U-shaped structure. The two vertical ends of the isolation plate 31 are arranged in an inclined state; a soft brush 32 is arranged below the anti-error plate 21; a triangular plate 33 is installed below the detonator 1; discharge grooves 34 are opened at the left and right ends of the anti-error plate 21, and 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.

[0031] It should be noted that the isolation plate 31 is an inverted U-shaped structure that cooperates with the bottom plate 25 to surround the button key 12 in the middle to form a relatively closed space. Such a structural design makes it difficult for dust and mineral particles to pass through the upper and lower ends of the button key 12 and enter the vicinity thereof. Since the two vertical ends of the isolation plate 31 are arranged in an inclined shape, and there is a gap between the two vertical ends of the isolation plate 31 and the inclined surface of the triangular plate 33 to form a channel, and the channel is connected to the discharge grooves 34 opened at the left and right ends of the anti-error plate 21, the pollution of the button key 12 by external dust and mineral particles is reduced, and the dust on the button key 12 can be discharged. The specific operation is that when the button key 12 needs to be operated and the anti-error plate 21 slides upward, the soft brush 32 arranged under the anti-error plate 21 will contact the surface of the button key 12 as the anti-error plate 21 moves. The soft brush 32 can brush up the dust attached to the surface of the button key 12 through friction with the surface of the button key 12 for cleaning. The brushed dust will be discharged from the discharge groove 34 along the channel under the guidance of the isolation plate 31, the triangular plate 33 and the discharge groove 34, thereby realizing timely cleaning of the dust on the surface of the button key 12, and discharging the cleaned dust out of the device, keeping the environment around the button key 12 relatively clean, and reducing problems such as false touches caused by dust accumulation. Through the protection of the isolation plate 31 and the cleaning effect of the soft brush 32, the dust and mineral particles on the surface of the button key 12 can be effectively removed, so that it can always remain in a relatively clean state.

[0032] like Figure 1 , Figure 8 and Fig.10 As shown, the anti-error plate 21 is located above the soft brush 32 and is threadedly connected with a screw rod 311, and a turntable 312 is installed at the end of the screw rod 311 away from the soft brush 32, and a limit support frame that slides through one side of the anti-error plate 21 is installed at the left and right ends of the soft brush 32, and a limit seat 313 is installed at the front end of the anti-error plate 21, and the limit seat 313 is formed by an arc shape and a horizontal shape. One side of the turntable 312 is connected with a rotating block 314 through the slide rail 22, and the rotating block 314 has an L-shaped structure, and a T-slot is provided on the side of the arc shape of the limit seat 313 away from the anti-error plate 21, and the end of the rotating block 314 away from the connecting head 213 slides through the T-slot, and an auxiliary rod 315 is rotatably connected to the middle part of the horizontal end of the limit seat 313, and the moving end of the auxiliary rod 315 is rotatably connected to the horizontal end of the rotating block 314, and a pull rod 316 is installed on the side wall of the horizontal end of the rotating block 314.

[0033] When the pull rod 316 is pulled, the pull rod 316 drives the rotating block 314 with an L-shaped structure to slide in the T-slot of the arc-shaped part of the limiting seat 313, so that the rotating block 314 changes its angular position. The rotating block 314 is connected to the turntable 312 through the slide rail 22. When the rotating block 314 rotates, the turntable 312 is driven to rotate via the slide rail 22. The rotation of the turntable 312 drives the screw rod 311 to rotate. When the screw rod 311 rotates on the anti-mistake plate 21, it retracts and contracts by virtue of the connection relationship established with the soft brush 32 through the limiting support frame, thereby driving the soft brush 32 to retract and contract. When the screw rod 311 is extended, the soft brush 32 extends backward, and when it is retracted, the soft brush 32 retracts forward. The extension and retraction of the soft brush 32 can be accurately adjusted according to the actual situation of the dust on the surface of the button key 12, such as the amount of dust, the stubbornness of the dust, etc., to achieve targeted cleaning.

[0034] It is worth noting that the auxiliary rod 315 can move telescopically, which can better adapt to the rotation changes of the rotating block 314 and play a role in buffering stress.

[0035] like Fig. 9 and Fig.11 As shown, two sleeves 321 are installed at the rear end of the detonator 1, and a driving block 322 is installed at the end of the lower part of the two anti-error plates 21 away from the detonator 1. A driving rod 323 is installed on the top of the driving 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 return spring rod 23. The end of the pipe 324 away from the sleeve 321 slides through the anti-error plate 21 and is fixedly connected to the isolation plate 31. A plurality of first injection slots 325 are provided at the horizontal end of the isolation plate 31, and the first injection slots 325 are connected to the pipes 324. Second injection slots 326 connected to the pipes 324 are provided on the opposite sides of the two vertical ends of the isolation plate 31, and the second injection slots 326 are arranged obliquely on the inner side of the isolation plate 31 along the direction of the button key 12.

[0036] It should be noted that when the anti-mistake plate 21 is opened, the slider 24 connected thereto will move upward. Since the slider 24 is connected to the driving block 322, the upward movement of the slider 24 will drive the driving block 322 to move together. There is a certain amount of gas in the sleeve 321. When the driving 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 toward the isolation plate 31. After passing through the pipe 324, the gas will be ejected from the multiple first injection slots 325 and the second injection slots 326 opened on the isolation plate 31 respectively. The first spray slot 325 is located at the horizontal end of the isolation plate 31, and the sprayed gas can directly act on the surface of the button key 12 and its surrounding area to blow and clean any impurities such as dust and mineral particles that may remain. The second spray slot 326 is located on the opposite sides of the two vertical ends of the isolation plate 31 and is arranged obliquely along the direction of the button key 12. This arrangement allows the gas sprayed from the second spray slot 326 to blow toward the surface of the button key 12 at a certain inclination angle, forming a multi-angle blowing effect, further enhancing the cleaning effect on the surface of the button key 12 and the surrounding corners that are difficult to clean, thereby more comprehensively removing impurities that may exist around the button key 12, keeping the button key 12 and its surrounding environment clean, and reducing the probability of problems such as false touches due to impurity accumulation.

[0037] like Fig.12 As shown, ear seats 241 are installed at both ends of the top of the slider 24, the top of the anti-error 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-error plate 21, and a magnetic strip attracted to the magnet is installed at one end of the slider 24 close to the anti-error plate 21.

[0038] It should be noted that the anti-error plate 21 can rotate around the rotation axis in the ear seat 241. At the same time, the magnets installed on the two vertical ends of the anti-error plate 21 and the magnetic strip installed on the slider 24 near one end of the anti-error plate 21 attract each other, and the magnetic force plays an auxiliary fixing and positioning effect, which not only ensures that the anti-error plate 21 can be relatively stably located on the slider 24 under normal conditions, but also allows the anti-error plate 21 to rotate smoothly around the rotation axis in the ear seat 241 under a certain external force. When it is necessary to replace the soft brush 32 or finely process the surface of the button key 12, the operator can apply appropriate external force to overcome the attraction between the magnet and the magnetic strip, so that the anti-error plate 21 rotates around the rotation axis in the ear seat 241. The design of the rotating connection greatly improves the convenience of replacing the soft brush 32 and finely processing the surface of the button key 12.

[0039] It is worth noting that Fig.13 As shown, an intelligent electric push rod is installed in the middle of the rear end of the detonator 1, and the moving end of the intelligent electric push rod is fixedly connected to the middle of the driving block 322. The device is equipped with a high-precision gas sensor and a dust sensor to monitor the gas concentration, dust content and other environmental parameters at the blasting operation 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 push rod, cut off the power supply of the detonating device, and thus prevent misfire.

[0040] The working principle of the present invention is that the intelligent locking device for preventing accidental explosion in mine blasting, when used: Locking process: Release the first reset spring rod 23, the slider 24 slides along the slide rail 22 to the bottom of the detonator 1 under the action of the spring force, and the anti-error plate 21 blocks the button key 12. At the same time, the unlocking plate 26 moves with the slider 24, and its bevel contacts the bevel of the lock plate 28, pushing the lock plate 28 to compress the second reset spring rod 27. When the unlocking plate 26 completely enters the bottom plate 25, the lock plate 28 is inserted into its socket to lock the anti-error plate 21; Unlocking process: the lock plate 28 is moved down along the linkage groove so that its top end is disengaged from the socket, the first return spring rod 23 releases potential energy, the slider 24 drives the anti-mistake plate 21 to move away, exposing the button key 12, and the concave plate 291 is connected to the lock plate 28. The inner rubber pad increases the friction force to facilitate unlocking, and the vertical end of the concave plate 291 is in the moving groove 29 to prevent accidental sliding unlocking; Power supply control of the cable connector 14: During the operation to prevent accidental explosion, the unlocking plate 26 is inserted into the bottom plate 25, and its bevel contacts the bevel of the driving plate 216, pushing the driving plate 216 to drive the connecting block 215 to move outward, and the connecting head 213 is separated from the interface 13, compressing the expansion spring 214 to achieve the purpose of cutting off the power supply. During unlocking, the unlocking plate 26 is separated, and the expansion spring 214 pushes the connecting head 213 to insert into the interface 13 to restore the connection; Dust cleaning component 3: The isolation plate 31 is in an inverted U shape and cooperates with the bottom plate 25 to surround the button key 12. Its vertical end is inclined to open a channel connected to the discharge slot 34 of the anti-error plate 21 to prevent dust from entering and also to discharge dust. When the anti-error plate 21 moves, the soft brush 32 contacts the button key 12 to clean the dust. Through the structures such as the screw rod 311, the turntable 312, the rotating block 314, and the pull rod 316, the pull rod 316 can be pulled to rotate the rotating block 314, and the screw rod 311 is rotated through transmission to drive the soft brush 32 to retract and retract, adjust the cleaning force, open the anti-error plate 21, and the slider 24 drives the driving block 322. The driving rod 323 slides in the sleeve 321 to squeeze the gas. The gas is ejected from the first injection slot 325 and the inclined second injection slot 326 of the isolation plate 31 through the pipeline 324 to clean the button key 12 and the dust around it.
