Description

Technical Field

[0001] This utility model relates to the technical field of drainage systems, specifically to a protective device for a scattered drainage system in an underground well. Background Technology

[0002] The mining environment in underground mines is complex and unique. As the mining depth increases, the ground stress, ground temperature, gas pressure, and groundwater pressure rise simultaneously, and the amount of groundwater inflow increases exponentially. Deep rock masses have well-developed fissures, and old goafs, faults, and aquifers are interconnected, forming a network of "water chains." Once these are breached, a water inrush disaster occurs, with instantaneous flow rates reaching thousands of cubic meters per hour, water temperatures as high as 40–60°C, and carrying corrosive chemical ions.

[0003] According to Chinese Patent No. CN118997842A, a temporary drainage device for underground mines is disclosed, comprising: a base, multiple extension components arranged on the sides of the base, each extension component including a fixed seat, a telescopic rod connected to one side of the fixed seat, a circular base connected to one end of the telescopic rod, a conveying device disposed on the surface of the circular base, the conveying device including a first submersible pump, a first conveying pipe connected to one side of the first submersible pump, multiple support components respectively disposed on the surfaces of the multiple telescopic rods, a placement component disposed between the multiple support components, two second submersible pumps respectively disposed on the base and the placement component, and a conveying component disposed between the two second submersible pumps. This invention provides a temporary drainage device for underground mines, which, when performing temporary drainage underground, can increase the number of submersible pumps according to the discharge location and limited space to centrally treat and transport groundwater, thereby increasing the overall drainage capacity.

[0004] However, during the installation of existing drainage system pipes, due to the winding and narrow underground roadways, broken surrounding rock, and the fact that drilling often results in enlarged or skewed boreholes, some drainage pipes cannot be tightly attached to the borehole wall and are suspended inside the drainage hole without being effectively fixed. This causes severe vibration and fatigue stress when high-speed water flows through. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that, during the installation of existing drainage system pipes, due to the winding and narrow underground roadways, broken surrounding rock, and the fact that drilling often results in enlarged or skewed hole diameters, some drainage pipes cannot be tightly attached to the hole wall and are suspended in the drainage hole without being effectively fixed, causing severe vibration and fatigue stress when high-speed water flows through.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A protective device for a scattered drainage system in a well includes a mounting base with fixing holes. A loading seat is fixed on the mounting base, and a rotating groove is formed on the loading seat. A rotating plate is rotatably connected within the rotating groove of the loading seat. A limiting plate is fixed to the outside of the loading seat on the rotating plate. Both the limiting plate and the loading seat have limiting holes. The limiting plate and the loading seat are connected by a limiting rod. A clamping bracket is fixed on the rotating plate. Three lifting screws are internally threaded onto the clamping bracket. A clamping plate is movably connected to the lower side of each lifting screw. The rotating plate can rotate within the loading seat and be quickly locked by the limiting rod, allowing the clamping bracket to adapt to any well wall inclination angle. The three lifting screws are distributed at 120° angles and press down on the clamping plate sequentially, forming a uniform circumferential force on the drainage pipe and preventing deformation due to single-point stress.

[0008] As a preferred embodiment of this utility model, the mounting base has a sliding track, the cavity of the sliding track is convex, and a sliding block moves within the cavity of the sliding track.

[0009] As a preferred embodiment of this utility model, the mounting base has a fixing groove next to the sliding track, and the sliding block is fixed to the mounting base by bolts, with the bolts of the sliding block inside the fixing groove of the mounting base.

[0010] As a preferred embodiment of this utility model, the loading seat slides within the sliding block. Both the sliding block and the loading seat have snap-fit ​​holes on their sides. A spring bracket is fixed to the side of the sliding block. The spring bracket consists of a spring return rod and a snap-fit ​​rod. The snap-fit ​​rod of the spring bracket is connected to the snap-fit ​​hole. The spring return rod of the spring bracket pushes the snap-fit ​​rod to automatically insert into the snap-fit ​​hole, realizing a "blind insertion" connection between the loading seat and the sliding block. Disassembly can be achieved simply by pulling the return rod.

[0011] As a preferred technical solution of this utility model, a telescopic rod is hinged between the clamping bracket and the loading seat. The telescopic rod consists of a telescopic base and an extension rod. The telescopic base and the extension rod are fixed by bolts. The telescopic rod is hinged between the clamping bracket and the loading seat to form a triangular stable structure. After the bolts are locked, vibration and impact from the pipeline can be absorbed, and the lifting screw can be prevented from loosening due to long-term dynamic load.

[0012] As a preferred technical solution of this utility model, the clamping plate has a connecting hole, the clamping bracket has a connecting rod fixed inside, the rear half of the connecting rod is inside the connecting hole of the clamping plate, the clamping plate slides up and down along the connecting rod through the connecting hole, restricts circumferential rotation, and ensures that the plate surface is always horizontal during the lifting process, and an assist rod is fixed on the lifting screw.

[0013] The beneficial effects of this utility model are as follows:

[0014] Because this utility model has an angle adjustment function, it can easily clamp and fix the discharge pipe, thereby reducing the risk of joint loosening and fatigue rupture caused by pipe suspension, offset or vibration, reducing the incidence of water inrush accidents, and ensuring the long-term stable operation of the underground drainage system.

[0026] Example 1

[0027] exist Figure 1-5 This utility model provides a technical solution: a protective device for a scattered drainage system in an underground well, including a mounting base 1 with a fixing hole 14, a loading seat 2 fixed on the mounting base 1, a rotating groove on the loading seat 2, a rotating plate 3 rotatably connected within the rotating groove of the loading seat 2, a limiting plate 4 fixed to the outside of the rotating plate 3 on the loading seat 2, both the limiting plate 4 and the loading seat 2 having limiting holes, the limiting plate 4 and the loading seat 2 being connected by a limiting rod, and a clamping bracket 5 fixed on the rotating plate 3, the clamping bracket 5 being internally threaded with... There are three lifting screws 6. The lower side of the lifting screw 6 is movably connected to the clamping plate 7. The mounting base 1 is fixed to the well wall or base by bolts passing through the fixing hole 14. The rotating plate 3 rotates horizontally in the rotating groove of the loading seat 2, which drives the clamping bracket 5 and the clamped drainage pipe to adjust the orientation. After the angle is determined, the limit rod is inserted to lock the limit plate 4 and the loading seat 2 to prevent rotation during operation. The three lifting screws 6 are rotated in sequence, and the clamping plate 7 is pushed down by the thread pair to press and fix the end of the drainage pipe, realizing quick clamping and height positioning.

[0028] In one aspect of this embodiment, a sliding track 8 is provided on the mounting base 1. The cavity of the sliding track 8 is U-shaped. A sliding block 9 moves within the cavity of the sliding track 8. A fixing groove is provided next to the sliding track 8 on the mounting base 1. The sliding block 9 is fixed to the mounting base 1 by bolts. The bolts of the sliding block 9 are in the fixing groove of the mounting base 1. A loading seat 2 slides within the sliding block 9. Both the sliding block 9 and the loading seat 2 have snap-fit ​​holes on their sides. A spring bracket 10 is fixed to the side of the sliding block 9. The spring bracket 10 consists of a spring return rod and a snap-fit ​​rod. The snap-fit ​​rod of the spring bracket 10 is connected to the snap-fit ​​hole. The sliding block 9 moves back and forth along the U-shaped sliding track 8, driving the loading seat 2 and the entire clamping mechanism to adjust their longitudinal position. After reaching the desired position, the bolts are tightened to engage with the fixing groove, thus locking the sliding block 9. Pulling the return rod of the spring bracket 10 causes the snap-fit ​​rod to exit the snap-fit ​​hole, allowing for quick disassembly or relocation of the loading seat 2. After releasing the spring, the spring automatically resets and locks, enabling tool-free quick disassembly during maintenance.

[0029] In one aspect of this embodiment, a telescopic rod 11 is hinged between the clamping bracket 5 and the loading seat 2. The telescopic rod 11 consists of a telescopic base and an extension rod. The telescopic base and the extension rod of the telescopic rod 11 are fixed by bolts. A connecting hole is opened on the clamping plate 7. A connecting rod 12 is fixed inside the clamping bracket 5. The rear half of the connecting rod 12 is inside the connecting hole of the clamping plate 7. An assist rod 13 is fixed on the lifting screw 6. The extension rod of the telescopic rod 11 extends and retracts within the base to set the pitch angle of the clamping bracket 5. After the angle is determined, the bolts are tightened to lock it, forming a diagonal brace to prevent the bracket from shaking. The connecting rod 12 slides up and down along the connecting hole to provide rotational anti-torsion guidance for the clamping plate 7, ensuring that the clamping plate 7 remains horizontal when the three lifting screws 6 lift and lower synchronously.

[0030] The working principle of this utility model is as follows: During use, the mounting base 1 is fixed to the well wall or base through the fixing hole 14, forming a rigid mounting point; the sliding block 9 moves back and forth along the convex sliding track 8, driving the loading seat 2 and the entire clamping mechanism to adjust their longitudinal position. After reaching the position, the bolts are locked to achieve initial positioning; the rotating plate 3 rotates horizontally in the rotating groove of the loading seat 2, driving the clamping bracket 5 and the clamped drainage pipe to adjust their horizontal orientation. The limiting rod is inserted into the limiting plate 4 and the limiting hole of the loading seat 2 and locked to prevent rotation during operation; the extension rod of the telescopic rod 11 extends and retracts in the base, setting the pitch angle of the clamping bracket 5. After tightening the bolts, it forms a diagonal brace to prevent the bracket from shaking; the three lifting screws 6 are rotated in sequence, using the threaded pair to push the clamping plate 7 down, and the connecting rod 12 slides along the connecting hole to provide... The anti-torsion guide ensures that the clamping plate 7 remains horizontal, pressing and fixing the end of the drain pipe. Pulling the spring rod of the spring bracket 10 allows the locking rod to exit the locking hole, quickly disassembling or adjusting the height of the loading seat 2. After releasing, the spring automatically resets and locks, achieving tool-free quick disassembly. During "scattered drainage" operations, after the drain pipe is pressed by the clamping plate 7, the entire clamping mechanism forms a rigid triangular support through the loading seat 2, rotating plate 3, and telescopic rod 11, effectively resisting the lateral impact and vibration caused by the gushing water flow in the well. The pitch angle of the clamping bracket 5 is adjustable, ensuring that the drain pipe inlet always faces downwards towards the water accumulation point, preventing scattered water flow from splashing along the well wall and achieving centralized pumping. The sliding block 9 moves horizontally, extending the drain pipe outlet to the outside of the well wall or connecting it to the main drain pipe to prevent backflow, thus providing full protection for "scattered drainage" operations.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
