A mine water blocking device

Abstract

This application provides a mine water blocking device, including a triggering component, a supporting component, a locking component, and a main frame. The triggering component includes a trigger head, a trigger rod, and a counterweight rod. The counterweight rod is sleeved on the outside of the trigger rod, and the trigger rod can move along the inner wall of the counterweight rod. The main frame is hinged to the top of the counterweight rod. The supporting component includes a supporting bone and a movable disc. The supporting bone is connected to the main frame, and one end of the supporting bone is hinged to the edge of the movable disc. The movable disc is sleeved on the outer wall of the counterweight rod. The locking component is disposed inside the movable disc. The movement of the trigger rod triggers the locking component. The movable disc has an open state that unfolds the main frame and a closed state that retracts the main frame. The movement of the trigger head and the trigger rod unlocks the locking structure, causing the movable disc to move, the main frame to unfold, and a water blocking wall to be quickly formed. After the water blocking device is unfolded, the counterweight rod can fall at an angle to the water surface, allowing the main frame to form a skeleton structure, providing a higher support effect for the formation of the water blocking wall.

Description

Technical Field

[0001] This application relates to the field of mining equipment technology, specifically to a mine water blocking and shut-off device. Background Technology

[0002] With the development of the times, the amount of minerals collected is increasing year by year. During the mining and collection process, the rock mass is damaged by the disturbance of mining, which inevitably leads to the conduction of aquifers and the influx of groundwater into the roadway, that is, the occurrence of water inrush accidents. Once the inrush water volume exceeds the drainage capacity of the mine, there is a high probability of causing a mine flooding accident, which seriously threatens the normal operation of underground work.

[0003] To address water inrush accidents, existing technologies mostly employ aggregate accumulation or structural blocking methods. These methods involve extending impact-resistant structures into the inrush area or using expandable grid structures. However, if the inrush lasts too long, resulting in excessively high water flow and velocity, it becomes difficult for workers to directly enter the mine to intercept the flow. Directly dumping aggregate into the well may result in it being washed away before it sets, failing to form a blocking wall and leading to low interception efficiency. To address this, existing technologies often use fishing nets, chains, or other structures to create a support frame before adding aggregate, thus intercepting and blocking it for faster accumulation. Alternatively, bags can be used to form a blocking wall. However, the lightweight fishing nets and chains in these methods are difficult to position in the mine tunnels, and they may be washed away by the water flow. While bags are easy to position and form, their excessive weight makes them difficult to transport and handle.

[0004] Therefore, the existing technology needs further improvement. Summary of the Invention

[0005] This application provides a mine water blocking device to solve the problems of difficult operation, difficulty in ensuring aggregate retention, complex structure, and poor water blocking effect of existing water blocking structures.

[0006] The technical solution adopted in this application is as follows:

[0007] This application provides a mine water interception and blocking device. The mine water interception and blocking structure includes a triggering component, a support component, a locking component, and a main frame. The triggering component includes a trigger head, a trigger rod, and a counterweight rod. The trigger head is connected to the trigger rod, and the counterweight rod is sleeved on the outside of the trigger rod. The trigger rod can move along the inner wall of the counterweight rod. The main frame is hinged to the top of the counterweight rod. The support component includes a support bone and a movable disk. The support bone is connected to the main frame, and one end of the support bone is hinged to the edge of the movable disk. The movable disk is sleeved on the outer wall of the counterweight rod. The locking component is disposed inside the movable disk. The movement of the trigger rod triggers the locking component. The movable disk has an open state that unfolds the main frame and a closed state that retracts the main frame.

[0008] Preferably, the support assembly further includes a fixing plate, which is disposed at the top of the counterweight rod and its edge is hinged to the main bone. The fixing plate can abut against the bottom of the trigger head.

[0009] Preferably, at the connection between the main bone and the supporting bone, one of them is provided with a sliding member, and the other of them is provided with a mating member, so as to achieve a sliding connection through the sliding member and the mating member.

[0010] Preferably, the mine interception and water blocking structure further includes a first elastic element. The fixed plate is provided with a bearing groove, the first elastic element is disposed in the bearing groove and sleeved on the outer wall of the trigger rod, and its two ends abut against the inner bottom wall of the bearing groove and the bottom of the trigger head, respectively.

[0011] Preferably, a stop is provided at the hinge between the movable disc and the supporting bone, and at the hinge between the fixed disc and the main bone.

[0012] Preferably, the locking assembly includes a base and a pressing member. The base is fixed to the inner wall of the movable disk, and the outer wall of the counterweight rod is provided with a first positioning hole. The pressing member can enter the first positioning hole to limit the closed state.

[0013] Preferably, the end of the trigger rod is provided with a guide portion, and the head end of the pressing member is provided with a mating portion. The guide portion and the mating portion can abut against each other to push the pressing member to move towards the base.

[0014] Preferably, the outer wall of the counterweight rod is provided with a second positioning hole, which is positioned higher than the first positioning hole. The side wall of the trigger rod is provided with multiple mating grooves that are adapted to the second positioning hole. The pressing member can enter the second positioning hole and abut against the mating groove to limit the opening state.

[0015] Preferably, the mine interception and water blocking structure further includes a casing structure and a second elastic element. The casing structure is sleeved on the outer wall of the counterweight rod, and the second elastic element is located inside the casing structure and sleeved on the outer wall of the counterweight rod. Its two ends abut against the bottom of the moving disk and the inner bottom wall of the casing structure, respectively.

[0016] Preferably, a hook structure is provided at the end of the main bone away from the trigger head.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0018] 1. In the event of a water inrush accident in a mine, the user only needs to place the water-blocking device into the mine. The device, through the cooperation of the frame and triggering components, achieves the water-blocking effect. The structure is simple, the operation is convenient, and no workers need to enter the mine, thus ensuring worker safety to a certain extent. Furthermore, due to the weight of the trigger head and counterweight rod, the water-blocking device can be placed into the mine with the trigger head pointing downwards. When the trigger head contacts the water surface in the mine, the impact causes the trigger head to strike the water surface, driving the trigger rod along the counterweight rod. The device moves away from the water surface to unlock the locking structure, allowing the moving disc to move along the counterweight rod. This causes the main frame to unfold, forming a blocking structure to intercept aggregates and other debris, thus quickly creating a water-blocking wall. Furthermore, due to the counterweight rod, the vertically descending intercepting and blocking device, after touching the water surface and unfolding, can fall down under the action of the counterweight rod, creating an angle between the main frame and the water surface. This allows the main frame to form a skeletal structure, providing greater support for the formation of the water-blocking wall and optimizing the interception and blocking effect.

[0019] 2. As a preferred embodiment of this application, this application provides a fixed plate at the top of the counterweight rod. Through the cooperation between the fixed plate and the movable plate, the movable plate, after being triggered by the trigger rod to lock the component, drives the main rib to move via the support bone, thereby increasing the diameter of the umbrella surface formed by the main rib and improving the water-blocking effect. Furthermore, the fixed plate facilitates the disassembly and assembly of the equipment, further improving the convenience of use. On the other hand, the fixed plate can abut against the bottom of the trigger head, providing a certain load-bearing effect for the trigger head, increasing the contact area at the bottom of the trigger head, and preventing the trigger head from directly impacting the counterweight rod and causing damage to both.

[0020] 3. As a preferred embodiment of this application, by setting a sliding connection between the main bone and the supporting bone, the deployment of the main bone is facilitated. This not only guides the movement of the main bone and prevents it from deviating during deployment, but also makes the sliding between the main bone and the supporting bone smoother, optimizing the deployment effect and thus improving the water-blocking effect. In addition, the first elastic element can buffer the impact of the trigger head to prevent damage caused by excessive impact, and also has a reset effect on the trigger head. After the trigger head collides and drives the trigger rod to move, the rebound effect of the first elastic element resets the position of the trigger head, which facilitates the subsequent use of the water-blocking device.

[0021] 4. As a preferred embodiment of this application, by setting a locking component including a base and a pressing member, the main bone can be restricted from unfolding when the pressing member is fixed in the first positioning hole, so that the main bone is in a closed state. After the trigger head hits and drives the trigger rod to move, the guide part of the trigger rod abuts against the mating part of the pressing member, so that the pressing member leaves the first positioning hole, allowing the moving plate to move along the counterweight rod, thereby allowing the main bone to change from a closed state to an open state. This not only achieves the positioning effect, but also facilitates the unfolding and storage of the main bone. The structure is simple and the operation is convenient.

[0022] 5. As a preferred embodiment of this application, by providing a second elastic element, after the pressing member leaves the first positioning hole, the elastic force of the second elastic element can push the moving disk to move, thereby supporting the moving disk and restricting its movement in the opposite direction; conversely, the moving disk will disengage from the counterweight rod. Furthermore, the sleeve structure can bear the load of the second elastic element and limit the position and compression direction of the second elastic element, reducing the phenomenon of the second elastic element deflecting during compression and rebound.

[0023] 6. As a preferred embodiment of this application, the hook structure allows the water-blocking device to be placed in the well and, after the umbrella ribs are deployed, to be hung on the support, grid, or mesh structure of the inner wall of the mine roadway via the hook structure. Alternatively, by placing multiple water-blocking devices, adjacent water-blocking devices can be connected through the hook structure. This improves the positioning effect of the water-blocking device and reduces the impact of water flow on it. Furthermore, the interconnected or roadway-connected water-blocking structures can expand the interception area, thereby facilitating the formation of the water-blocking wall and further improving the amount of aggregate retained and the water-blocking effect.

[0038] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0039] In the description of this application, it should be understood that the terms "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] The technical solutions protected in this application are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the scope of protection of this application. Although this application has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this application are within the scope of protection claimed in this application.

[0042] like Figures 1 to 5 As shown, this application provides a mine water interception and blocking device. The mine water interception and blocking structure includes a triggering component 1, a support component 2, a locking component 3, and a main frame 4. The triggering component 1 includes a trigger head 11, a trigger rod 12, and a counterweight rod 13. The trigger head 11 is connected to the trigger rod 12, and the counterweight rod 13 is sleeved on the outside of the trigger rod 12. The trigger rod 12 can move along the inner wall of the counterweight rod 13. The main frame 4 is hinged to the top end of the counterweight rod 13. The support component 2 includes a support bone 21 and a movable disk 22. The support bone 21 is connected to the main frame 4, and one end of the support bone 21 is hinged to the edge of the movable disk 22. The movable disk 22 is sleeved on the outer wall of the counterweight rod 13. The locking component 3 is disposed inside the movable disk 22. The movement of the trigger rod 12 triggers the locking component 3. The movable disk 22 has an open state that unfolds the main frame 4 and a closed state that retracts the main frame 4.

[0043] Optionally, the structure of the trigger head 11 is as follows: Figure 1 and Figure 2 As shown, the top has an arc-shaped structure, which can improve the impact effect of the trigger head 11 on the water surface to a certain extent. The bottom has a flat structure, which can better contact the counterweight rod 13 and facilitate the connection with the trigger rod 12. The trigger head 11 and the trigger rod 12 can be a one-piece structure or a separate structure, which can be connected and assembled by welding, screwing, plugging or other methods.

[0044] In the open and closed states, the locking component 3 fixes the position of the moving disk 22, the trigger head 11 is not impacted, and the trigger rod 12 cannot move, thus keeping the main bone 4 in the closed state. In the open state, the trigger rod 12 moves due to the impact of the trigger head 11 and triggers the locking component 3, thus allowing the moving disk 22 to move upward along the counterweight rod 13 and drive the support bone 21 to push against the main bone 4, so that the main bone 4 is in the open state, increasing the umbrella radius of the main bone 4 and thus improving the interception effect.

[0045] Among them, such as Figure 1 and Figure 3 As shown, the main bone 4 is an umbrella-shaped structure formed by multiple umbrella-like structures. After the trigger head 11 is impacted and the trigger rod 12 moves, the support bone 21 is also provided with multiple umbrella-like structures, the number of which is the same as the number of umbrella-like structures in the main bone 4. With the cooperation of the support bone 21 and the main bone 4, and the up and down movement of the moving disk 22, the opening and closing of the main bone 4 can be switched.

[0046] Preferably, in order to facilitate the connection between the main bone 4 and the supporting bone 21 and the unfolding of the main bone 4, at the connection between the main bone 4 and the supporting bone 21, one of them is provided with a sliding member and the other is provided with a mating member, so as to achieve a sliding connection through the sliding member and the mating member.

[0047] like Figure 1 and Figure 2 As shown, a mating part is provided on the side of the supporting bone 21 that contacts the main bone 4. The mating part can be a sliding groove. The main bone 4 can be provided with a sliding part that matches the sliding groove, such as a slider, a rib, or other structure. Through the sliding cooperation between the two, when the supporting bone 21 moves the main bone 4 due to the movement of the moving disk 22, the unfolding direction of the main bone 4 can be restricted, preventing the main bone 4 from deflecting during the unfolding process. The unfolding of the main bone 4 can also be made smoother and the structure simpler through the sliding connection.

[0048] Of course, in addition to the above-mentioned configuration, the sliding parts and mating parts can also be configured with a slider structure on the support bone 21 and a sliding groove structure on the main bone 4, or other sliding mating methods such as pulley structures.

[0049] Furthermore, the locking component 3 includes a base 31 and a pressing member 32. The base 31 is fixed to the inner wall of the movable disk 22, and the outer wall of the counterweight rod 13 is provided with a first positioning hole. The pressing member 32 can enter the first positioning hole to limit the closed state.

[0050] It is understandable that the pressing member 32 can be an elastic member and can be housed in the base 31 so that when the moving plate 22 moves to the first positioning hole, the pressing member 32 enters the first positioning hole due to the elastic force of the elastic member itself, locking the inner wall of the moving plate 22. Since the trigger rod 12 can move on the inner wall of the counterweight rod 13, in order to facilitate the pressing member 32 entering the first positioning hole and the trigger rod 12 triggering the pressing member 32, the length of the trigger rod 12 is less than the length of the counterweight rod 13. The first positioning hole is set below the trigger rod 12 and has a certain distance between it and the bottom end of the trigger rod 12. This distance is slightly less than the distance that the trigger head 11 can move towards the counterweight rod 13, so that after the trigger head 11 is impacted, it can drive the trigger rod 12 to trigger the pressing member 32. The pressing member 32 leaves the first positioning hole, so that the locking component is unlocked, thereby allowing the moving plate 22 to move, so as to release the closed state and guide the main bone 4 to switch to the open state.

[0051] Furthermore, in order to ensure that the main frame 4 can maintain the radius of its expanded umbrella surface when it is open, the outer wall of the counterweight rod 13 is provided with a second positioning hole. The position of the second positioning hole is higher than that of the first positioning hole. The side wall of the trigger rod 12 is provided with multiple mating grooves that are adapted to the second positioning hole. The pressing member 32 can enter the second positioning hole and abut against the mating groove to limit the opening state.

[0052] It should be noted that when the movable disc 22 is located at the first positioning hole, after the trigger rod 12 triggers the pressing member 32, the movable disc 22 can move downward along the inner wall of the counterweight rod 13 to release the closed state. The movable disc 22 moves upward along the outer wall of the counterweight rod 13, causing the main bone 4 to switch from the closed state to the open state. When the movable disc 22 moves to the second positioning hole, the pressing member 32, which was blocked by the outer wall of the counterweight rod 13, can relax at the second positioning hole and enter the second positioning hole, and then move into the second positioning hole, where it contacts the side wall of the trigger rod 12. The mating groove abuts against the main bone 4 to restrict its unfolding, preventing the main bone 4 from returning to a closed state due to the free movement of the moving disc 22 after unfolding. This allows the locking component to reposition the moving disc 22, ensuring the unfolding of the main bone 4, maintaining the umbrella surface radius of the main bone 4, increasing the water blocking area, and ensuring the water blocking effect. The pressing part 32 abuts against the mating groove, which also positions the trigger rod 12, reducing the phenomenon of the trigger rod 12 sliding out of the counterweight rod 13 during the water blocking process.

[0053] In a preferred embodiment, the end of the trigger rod 12 is provided with a guide portion 122, and the head end of the pressing member 32 is provided with a mating portion 33. The guide portion 122 and the mating portion 33 can abut against each other to push the pressing member 32 to move toward the base 31.

[0054] like Figure 1 and Figure 4 As shown, the guide part 122 and the mating part 33 can be a sloped structure that cooperates with each other, or a guide arc surface. Through the mutual contact of the guide part 122 and the mating part 33, on the one hand, the impact and damage of the trigger rod 12 to the pressing member 32 can be reduced, and the service life of the intercepting and blocking water device can be improved. On the other hand, the guide part 122 and the mating part 33 can make the pressing of the trigger rod 12 against the pressing member 32 smoother, and can reduce the friction between the trigger rod 12 and the pressing member 32, so as to make the locking structure release the lock on the moving plate 22 more quickly.

[0055] In a preferred embodiment of this application, the support component 2 further includes a fixing plate 23, which is disposed on the top of the counterweight rod 13 and its edge is hinged to the main bone 4. The fixing plate 23 can abut against the bottom of the trigger head 11.

[0056] The fixed plate 23 can be integrally formed with the counterweight rod 13 or welded to the top of the counterweight rod 13. The mine interception and water blocking structure also includes a first elastic element 231. The fixed plate 23 is provided with a bearing groove. The first elastic element 231 is provided in the bearing groove and sleeved on the outer wall of the trigger rod 12. Its two ends abut against the inner bottom wall of the bearing groove and the bottom of the trigger head 11, respectively.

[0057] Optionally, the size of the bearing groove is adapted to the size of the trigger head 11 so that after the trigger head 11 is hit by a collision or impact, it can move into the bearing groove and abut against the bottom wall of the bearing groove. On the one hand, the larger bottom area of ​​the bearing groove can reduce the damage to the counterweight rod 13 and the trigger head 11 caused by impact and collision. On the other hand, the bearing groove can accommodate the first elastic member 231, which not only provides a space for the first elastic member 231, but also restricts the compression direction and rebound direction of the first elastic member 231 through the outer wall of the bearing groove, preventing the first elastic member 231 from shifting during contraction and relaxation.

[0058] Furthermore, the first elastic element 231 can buffer the collision and impact of the trigger head 11. Moreover, through the rebound effect of the first elastic element 231, the locking component can be released after the water blocking device is used, so that the trigger rod 12 can move. At this time, under the elastic force of the first elastic element 231, the trigger head 11 is pushed back to the initial position, which is convenient to operate and facilitates the subsequent use of the water blocking device.

[0059] As a preferred embodiment of this application, a stop portion 5 is provided at the hinge joint between the movable disk 22 and the supporting bone 21 and at the hinge joint between the fixed disk 23 and the main bone 4.

[0060] like Figure 4 and Figure 5 As shown, baffles can be provided at the edges of both the movable disk 22 and the fixed disk 23 as stop parts 5. The baffles are provided on the upper and lower sides of the hinge between the movable disk 22 and the fixed disk 23, so that a groove 51 structure is formed at the hinge between the movable disk 22 and the fixed disk 23. The baffles restrict the rotation of the main bone 4 and the supporting bone 21, reduce the rotation angle of the main bone 4 and the supporting bone 21, and prevent the main bone 4 and the supporting bone 21 from breaking due to excessive rotation angle.

[0061] The groove 51 structure of the movable disk 22 and the fixed disk 23 is arranged around the movable disk 22 and the fixed disk 23. A positioning ring 52 is fixedly arranged in the groove 51 structure. The positioning ring 52 is arranged around the groove 51 structure. One end of the main bone 4 and the supporting bone 21 is provided with a hinge hole. The positioning ring 52 can pass through the hinge hole so that the main bone 4 and the supporting bone 21 can be hinged through the cooperation of the hinge hole and the positioning ring 52.

[0062] In addition, the groove 51 is also provided with a partition, which is located between adjacent main bones 4 and supporting bones 21 to reduce the collision between adjacent main bones 4 and supporting bones 21.

[0063] Preferably, the mine interception and water blocking structure further includes a casing 6 structure and a second elastic element 61. The casing 6 structure is sleeved on the outer wall of the counterweight rod 13, and the second elastic element 61 is located inside the casing 6 structure and sleeved on the outer wall of the counterweight rod 13. Its two ends abut against the bottom of the moving disk 22 and the inner bottom wall of the casing 6 structure, respectively.

[0064] Among them, such as Figure 5 As shown, the sleeve 6 structure is located at the middle position of the counterweight rod 13. Its shape is a cylindrical structure with an opening. The second elastic element 61 can be placed in the sleeve 6 structure so that the compression and relaxation of the second elastic element 61 can be positioned by the inner wall of the sleeve 6 structure, preventing the second elastic element 61 from deflecting during movement. Furthermore, since the second elastic element 61 can abut against the bottom of the moving disk 22, after the locking structure is unlocked, the elastic force of the second elastic element 61 can push the moving disk 22 to move upward along the outer wall of the counterweight rod 13, which plays a guiding role in the movement of the moving disk 22 and provides power for the movement of the moving disk 22. The structure is simple and the operation is convenient.

[0065] Specifically, during the use of the water-blocking device, the user needs to position the trigger head 11 towards the mine's feed inlet and insert the water-blocking device into the feed inlet. Under the weight of the trigger head 11 and the counterweight rod 13, the trigger head 11 will first contact the water surface. Since mine tunnels are generally more than 100 meters below the surface, the impact force after the water-blocking device is inserted into the mine at the aggregate feed inlet will cause the trigger head 11 to retract the trigger rod 12, making the trigger rod 12 contact the pressing member 32 located at the first positioning hole. This will then cause the pressing member 32 to move away from the first positioning hole. Under the elastic force of the second elastic element 61, the disc 22 moves toward the trigger head 11 and drives the support bone 21 to move synchronously. Driven by the support bone 21, the main bone 4 can unfold through the sliding connection with the support bone 21 and the hinge with the fixed disc 23, increasing its umbrella radius and changing from a closed state to an unfolded state. Furthermore, when the moving disc 22 moves to the second positioning hole, the pressing member 32 is pressed into the second positioning hole because there is no obstruction at the second positioning hole, and passes through the second positioning hole to abut against the mating groove of the trigger rod 12 to lock the position of the moving disc 22, so that the main bone 4 is always in the unfolded state.

[0066] During this process, due to the unfolding of the main frame 4 and the weight of the counterweight rod 13 itself, the intercepting and blocking device can tilt, so that the main frame 4 and the water surface have a certain angle, thereby intercepting the aggregate, which is conducive to forming a blocking wall structure and improving the blocking effect.

[0067] As a preferred embodiment of this application, such as Figure 1As shown, a hook structure 7 is provided at the end of the main frame 4 away from the trigger head 11. Since the inner wall of the mine roadway is often equipped with a support structure, grid structure or mesh structure to improve the strength of the roadway, the hook structure 7 can be hung on the inner wall of the roadway to improve the positioning effect of the interception and water blocking device and further improve the water blocking capacity. In addition, in order to improve the interception effect, multiple interception and water blocking devices can be put into place at one time, and adjacent interception and water blocking devices can also be connected through the hook structure 7, which increases the length of the water blocking wall structure, which is conducive to the retention of aggregate, thereby improving the skeleton strength of the water blocking wall structure and further ensuring the interception and water blocking effect.
