Description

Technical Field

[0001] This utility model relates to the field of prevention and protection devices, and in particular to a device for preventing and protecting mine water. Background Technology

[0002] Hydrogeological hazards are a significant threat to safe production during mining operations. As shallow resources gradually deplete and mining depths increase, hydrogeological conditions become more complex, and water hazards become increasingly prominent. Mine water hazards not only threaten the safety of underground workers but also cause equipment damage, production interruptions, and even major accidents. Therefore, mine water control and protection devices have become a crucial guarantee for safe mine production.

[0003] However, traditional mine water control and protection devices still have shortcomings in practical use: 1. Insufficient impact resistance: In mining environments, traditional protection devices often face the risk of ore falling from heights. These falling objects exert enormous impact on the device, causing structural deformation or damage, significantly shortening the device's service life; 2. Mine water inrush or seepage usually contains a large amount of impurities such as mud, sand, and gravel. Traditional devices lack effective filtration structures in their drainage systems, leading to pipe blockage, affecting drainage efficiency, and hard ore particles in the water may cause wear or damage to the internal structure of the device, further reducing its reliability.

[0004] Therefore, a mine water control and protection device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mine water control and protection device to solve the problems existing in the prior art, improve the protection of the device, and reduce the amount of mineral particles in the water.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a mine water prevention and protection device, comprising:

[0007] The housing has a protective mechanism on its top and filter mechanisms fixedly connected to both sides. Each filter mechanism includes an outer shell with a screen plate on its top, the screen plate being inclined. A filter screen is installed inside the outer shell, and a sand discharge hole is opened at the bottom of the outer shell. A first valve is installed on the sand discharge hole. Several pumps are fixedly connected inside the housing. The inlet of each pump is connected to the outer shell, and the outlet of each pump is connected to a hydrocyclone separator. The hydrocyclone separator has a clean water outlet and a sediment outlet. A water supply pipe is connected to the clean water outlet, and a discharge pipe is installed on the sediment outlet.

[0008] Preferably, the outer casing has a cleaning port, and a sealing baffle is rotatably connected to the outer casing. The sealing baffle is configured to correspond to the cleaning port, and the cleaning port is configured to correspond to the filter screen.

[0009] Preferably, a fixing plate is fixedly connected inside the outer shell, and a plurality of slots are provided on the fixing plate. A plug is fixedly connected to the filter screen, and the plug is adapted to the slot and inserted into the slot.

[0010] Preferably, the protective mechanism includes a top plate, which is arc-shaped and fixedly connected to a bottom plate. The bottom plate is mounted on the housing via a buffer mechanism.

[0011] Preferably, the buffer mechanism includes an upper cylinder and a lower cylinder. The upper cylinder is fixedly connected to the base plate, and the lower cylinder is fixedly connected to the housing. The upper cylinder is inserted into the lower cylinder. Springs are provided in the upper cylinder and the lower cylinder. The two ends of the springs are fixedly connected to the base plate and the housing, respectively.

[0015] This utility model discloses the following technical effects: In this device, the protective mechanism protects the device from damage caused by heavy objects such as stones. The inclined mesh plate facilitates the rolling off of stones and other objects, preventing them from accumulating on the top of the device. Simultaneously, the mesh plate prevents larger stones from entering the outer shell. Water passes through the mesh plate into the outer shell, where a filter screen further filters the water, removing smaller particles such as gravel. A pump draws the water from the outer shell to a hydrocyclone separator, which separates the water from the sediment. The separated water flows out from the clean water outlet, while the separated sediment is discharged from the sediment outlet. This reduces the sediment content in the water, facilitating water discharge. The sediment discharge hole allows for the removal of sediment and other debris from the outer shell. The first valve can be opened periodically to clean the inside of the outer shell, and the discharge pipe facilitates the removal of sediment. This utility model not only provides protection for the device through the protective mechanism but also reduces the sand and gravel content in the water through multiple filtrations, further facilitating water discharge.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figure 1-3 This utility model provides a mine water control and protection device, comprising:

[0024] The box body 1 has a protective mechanism on its top and a filter mechanism fixedly connected to both sides. The filter mechanism includes an outer shell 2, a mesh plate 3 on the top of the outer shell 2, the mesh plate 3 being inclined, a filter screen 4 inside the outer shell 2, a sand discharge hole 5 at the bottom of the outer shell 2, a first valve 6 on the sand discharge hole 5, and several pumps 7 fixedly connected inside the box body 1. The inlet of the pumps 7 is connected to the outer shell 2, and the outlet of the pumps 7 is connected to a hydrocyclone separator 8. The hydrocyclone separator 8 has a clean water outlet 9 and a sediment outlet 10. The clean water outlet 9 is connected to a water supply pipe 11, and a discharge pipe 12 is installed on the sediment outlet 10.

[0025] In this device, the protective mechanism is used to protect the device from being damaged by heavy objects such as stones. The screen plate 3 is set at an angle to facilitate the rolling off of objects such as stones and prevent them from accumulating on the top of the device. At the same time, the screen plate 3 can prevent larger stones from entering the outer shell 2. Water passes through the screen plate 3 and enters the outer shell 2. The filter screen 4 filters the water again, which can filter out smaller gravel particles, etc. The pump 7 pumps the water in the outer shell 2 to the hydrocyclone separator 8. The hydrocyclone separator 8 can separate water and silt. The separated water flows out from the clean water outlet 9, and the separated silt is discharged from the silt outlet 10. This can reduce the silt content in the water and facilitate water discharge. The sand discharge hole 5 facilitates the discharge of silt and other debris in the outer shell 2. The first valve 6 can be opened periodically to clean the inside of the outer shell 2. The discharge pipe 12 facilitates the discharge of silt.

[0026] The design is further optimized by providing a cleaning port 13 on the outer casing 2 and a sealing baffle 14 rotatably connected to the outer casing 2. The sealing baffle 14 is set to correspond with the cleaning port 13, and the cleaning port 13 is set to correspond with the filter screen 4.

[0027] The sealing baffle 14 is used to block the cleaning port 13 to prevent water from flowing out of the cleaning port 13, while the filter screen 4 can also be cleaned through the cleaning port 13. The connection and locking of the sealing baffle 14 to the housing 2 adopt existing technology.

[0028] In a further optimized design, a fixing plate 15 is fixedly connected inside the outer casing 2. Several slots are provided on the fixing plate 15. A rod 16 is fixedly connected to the filter screen 4. The rod 16 is adapted to the slot and is inserted into the slot.

[0029] The insertion of the rod 16 into the slot allows for a detachable connection between the filter screen 4 and the housing 2, facilitating the maintenance and replacement of the filter screen 4.

[0030] The design is further optimized. The protective mechanism includes a top plate 17, which is arc-shaped and fixedly connected to a bottom plate 18. The bottom plate 18 is installed on the housing 1 through a buffer mechanism.

[0031] The curved top plate 17 facilitates the rolling of stones and also prevents stones from accumulating on the top of the device. It also facilitates the flow of water to the outside, and the buffer mechanism can reduce the impact of stones on the box 1.

[0032] The further optimized scheme includes an upper cylinder 19 and a lower cylinder 20. The upper cylinder 19 is fixedly connected to the base plate 18, and the lower cylinder 20 is fixedly connected to the housing 1. The upper cylinder 19 is inserted into the lower cylinder 20. A spring 21 is installed inside the upper cylinder 19 and the lower cylinder 20. The two ends of the spring 21 are fixedly connected to the base plate 18 and the housing 1, respectively. A damper 22 is installed between the base plate 18 and the housing 1, and the damper 22 is located inside the spring 21.

[0033] The upper cylinder 19 can move within the lower cylinder 20. When the stone presses heavily on the top plate 17, the bottom plate 18 will compress the spring 21 and the damper 22. The damper 22 can absorb some of the impact energy and reduce the damage to the box 1.

[0034] The scheme is further optimized by fixing a connecting plate 23 on the mesh plate 3. Both the connecting plate 23 and the outer shell 2 are provided with threaded holes, and bolts 24 are threadedly connected in the threaded holes.

[0035] The connecting plate 23 and the outer shell 2 are detachably connected by bolts 24, which facilitates the maintenance and replacement of the mesh plate 3.

[0036] The scheme was further optimized by installing a second drain pipe 25 on the sand discharge hole 5, and installing the first valve 6 on the second drain pipe 25.

[0037] The drain pipe 25 facilitates the discharge of sand, gravel, and other debris from the outer casing 2.

[0038] The design is further optimized by fixing a first leg 26 to the box body 1 and a second leg 27 to the outer shell 2. A collection box 28 is set below the box body 1, and an excretion pipe 12 extends into the collection box 28.

[0039] The first leg 26 is used to support the box body 1, and the second leg 27 is used to support the outer shell 2.

[0040] The working principle of this device is as follows: the arc-shaped top plate 17 facilitates the rolling of stones and prevents them from accumulating on the top of the device. It also facilitates the outward flow of water. When stones press heavily on the top plate 17, the bottom plate 18 compresses the spring 21 and the damper 22. The damper 22 can absorb some of the impact energy and reduce damage to the housing 1. The inclined mesh plate 3 facilitates the rolling of stones and other objects and prevents them from accumulating on the top of the device. At the same time, the mesh plate 3 can prevent larger stones from entering the outer shell 2. Water passes through the mesh plate 3 and enters the outer shell 2. The filter screen 4 filters the water again, filtering out smaller stone particles. The pump 7 pumps the water in the outer shell 2 to the hydrocyclone separator 8. The hydrocyclone separator 8 can separate water and sediment. The separated water flows out from the clean water outlet 9, and the separated sediment is discharged from the sediment outlet 10. This reduces the sediment content in the water and facilitates water discharge. The first valve 6 can be opened periodically to clean the inside of the outer shell 2, and the sediment is discharged through the drain pipe 12.
