Description

Technical Field

[0001] This invention relates to the field of coal mine roadway support technology, and in particular to a leak-stopping device for water seepage treatment in coal mine mining roadways. Background Technology

[0002] In the field of coal mine roadway maintenance, sealing the water outlet of water-spraying roadways is a significant technical challenge. Water spraying in coal mine roadways can lead to problems such as softening of surrounding rock, corrosion of support structures, and deterioration of the working environment, which seriously affect the safe and efficient production of coal mines.

[0003] Existing methods for sealing water outlets in water-spraying tunnels mainly include cement grouting, chemical grouting, and mechanical sealing. However, these methods generally have the following shortcomings in actual construction: First, drilling and grouting need to be carried out in separate steps, which is cumbersome and time-consuming. Repeated disassembly and reassembly of equipment can easily lead to failure of the orifice seal, causing grout backflow or grouting pressure leakage. Second, after sealing, some water outlets still have trace amounts of seepage or residual water flowing disorderly along the tunnel surface. Existing solutions lack effective drainage and collection measures, resulting in water accumulation on the tunnel floor and a still damp working environment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a leak-stopping device for water seepage in coal mine roadways, achieving both efficient grouting and sealing as well as water seepage drainage and recovery functions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a leak-stopping device for water seepage treatment in coal mine mining roadways, comprising: The grouting anchoring assembly includes a grouting anchoring body that is connected to the roadway anchoring and is used for drilling and also serves as a grouting channel, and a detachable orifice mounting component that is installed on the exposed end of the grouting anchoring body and is used to seal the borehole orifice. The water guiding assembly includes a mounting base that is detachably connected to the orifice mounting component, and a water guiding plate that is detachably disposed between the two mounting bases and has a water guiding groove on the top; The liquid collection assembly includes a liquid collection section for receiving liquid discharged from the water guide plate, a diversion section connected to the liquid collection section, an external discharge section connected to one outlet of the diversion section, and a recovery filtration section connected to another outlet of the diversion section. The external discharge section directs the liquid to a designated discharge location, and the recovery filtration section filters and purifies the liquid before supplying it to the internal water replenishment point of the coal mine for reuse.

[0006] Furthermore, the grouting anchor body includes a hollow anchor rod and a drill bit disposed at one end of the hollow anchor rod. The hollow anchor rod consists of at least one rod body and a connecting sleeve threaded onto the rod body. The connecting sleeve is used to splice and fix two adjacent rod bodies. The orifice mounting component includes a grout stop plug fitted onto the hollow anchor rod and a pad located on the side of the grout stop plug away from the drill bit. The orifice mounting component also includes a nut that is threadedly connected to the hollow anchor rod.

[0007] Furthermore, the mounting base is disposed between the pad and the nut. The mounting base consists of two first collars and two second collars. The inner diameters of the first collars and the second collars are equal and both are larger than the diameter of the hollow anchor rod. The outer diameter of the first collar is larger than the outer diameter of the second collar, and they are staggered from top to bottom. The water guide plate includes two U-shaped plates, and a hinge is provided between the two U-shaped plates at the bottom of the U-shaped plates. Each of the two U-shaped plates has an arc-shaped groove at the end away from the hinge that can be engaged with the two first rings.

[0008] Furthermore, sealing strips are provided at both ends of the two U-shaped plates.

[0009] Furthermore, each of the two U-shaped plates has a pin seat at the bottom of the end near the hinge, and the pin seat has a socket for bolt installation.

[0010] Furthermore, the nut consists of a turning section and a retaining ring section located at the top of the turning section; The water guiding assembly also includes an extension component for misaligned installation of the water guiding plate. The extension component includes a third ring, a fourth ring, a fifth ring, and a sixth ring arranged sequentially from top to bottom. A connecting rod is fixedly connected between the third ring and the fourth ring. The third ring is sleeved on the bottom second ring and its inner diameter is smaller than that of the first ring and the outer diameter of the retaining ring section. The outer diameters of the fourth ring and the sixth ring are both larger than the outer diameter of the fifth ring, and the outer diameter of the fifth ring is equal to that of the second ring.

[0011] Furthermore, the diversion section includes a three-way diversion valve, the inlet of which is connected to the outlet of the collection section. The three-way diversion valve has a first outlet and a second outlet, the first outlet being connected to the external discharge section and the second outlet being connected to the recovery filter section. The three-way diversion valve is a manual switching valve or an electric switching valve electrically connected to the controller.

[0012] The beneficial effects of this invention are reflected in: This invention uses a grouting anchoring component to inject grout into the surrounding rock of the roadway to seal cracks, reducing water seepage at the source. At the same time, a water guiding component orderly diverts residual seepage water, and a liquid collection component diverts the collected seepage water according to its quality. Water with higher purity is purified by a recycling and filtration unit and then reused within the coal mine, while water with more impurities is discharged through an external discharge unit, thus achieving the goal of both efficient grouting and sealing and water seepage drainage and recycling.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-6 This invention discloses a leak-stopping device for water seepage treatment in coal mine roadways, comprising: The grouting anchoring assembly 1 includes a grouting anchoring body that is connected to the roadway anchoring and is used for drilling and also serves as a grouting channel, and a detachable orifice installation component that is installed on the exposed end of the grouting anchoring body and is used to seal the borehole orifice. The water guiding assembly 2 includes a mounting base 21 that is detachably connected to the orifice mounting component, and a water guiding plate 22 that is detachably disposed between the two mounting bases 21 and has a water guiding groove on its top. The liquid collection assembly includes a liquid collection section for receiving the liquid discharged from the water guide plate 22, a diversion section connected to the liquid collection section, an external discharge section connected to one outlet of the diversion section, and a recovery filtration section connected to another outlet of the diversion section. The external discharge section leads the liquid to a designated discharge location, and the recovery filtration section filters and purifies the liquid before supplying it to the internal water replenishment point of the coal mine for reuse.

[0017] This invention utilizes a grouting anchoring component 1 to inject grout into the surrounding rock of the roadway to seal cracks, reducing water seepage at the source. Simultaneously, a water guiding component 2 systematically diverts residual seepage water, and a liquid collection component distributes the collected seepage water according to its quality. Water with higher purity is purified by a recycling and filtration unit and then reused within the coal mine, while water containing more impurities is discharged through an external discharge unit. This comprehensive approach to managing roadway seepage water—including blocking, guiding, collecting, utilizing, and discharging—effectively improves the roadway working environment and reduces water waste.

[0018] In one embodiment, the grouting anchor body includes a hollow anchor rod and a drill bit 11 disposed at one end of the hollow anchor rod. The hollow anchor rod consists of at least one rod body 12 and a connecting sleeve 13 threaded onto the rod body 12. The connecting sleeve 13 is used to splice and fix two adjacent rod bodies 12. The orifice mounting component includes a grout stop plug 14 sleeved on the hollow anchor rod and a pad 15 located on the side of the grout stop plug 14 away from the drill bit 11. The orifice mounting component also includes a nut 16 threadedly connected to the hollow anchor rod.

[0019] With this design, the hollow anchor rod serves as both a drilling tool and a grouting channel. After the drill bit 11 is drilled into place, grouting can be performed directly without withdrawing the rod, simplifying the operation process. Multiple rods 12 can be flexibly spliced ​​together through the connecting sleeve 13 to adapt to different drilling depths. The grout stop plug 14 expands and seals the hole when it encounters grout, and works with the pad plate 15 to prevent grout leakage. After the nut 16 is tightened, it provides a solid foundation for the subsequent installation of the water guiding component 2. The structure is compact and the installation is reliable.

[0020] In one embodiment, the mounting base 21 is disposed between the pad 15 and the nut 16. The mounting base 21 is composed of two first collars 211 and two second collars 212. The inner diameters of the first collars 211 and the second collars 212 are equal and both are larger than the diameter of the hollow anchor rod. The outer diameter of the first collars 211 is larger than the outer diameter of the second collars 212, and they are arranged alternately from top to bottom. The water guide plate 22 includes two U-shaped plates 221. A hinge 222 is provided between the two U-shaped plates 221 at the bottom of the U-shaped plates 221. Each of the two U-shaped plates 221 has an arc-shaped groove at the end away from the hinge 222 that can be engaged with the two first rings 211.

[0021] With this design, the two U-shaped plates 221 can be folded and stored and unfolded and spliced ​​through hinges 222. After unfolding, the arc-shaped slots at both ends can be inserted between the two first rings 211 to complete the installation. The first rings 211 and the second rings 212 on the mounting base 21 are arranged alternately to form an annular slot, providing multiple installation positions for the water guide plate 22, which makes it easy to flexibly adjust the installation direction of the water guide plate according to the actual position of the water spray point.

[0022] Specifically, when the anchor bolt mounting surfaces are not at the same height, shims can be placed between the mounting base 21 and the pad 15 to level them.

[0023] In one embodiment, sealing strips are provided at both ends of the two U-shaped plates 221.

[0024] This design allows the sealing strips to form a flexible, tight seal between the ends of the U-shaped plate 221, preventing water from leaking through the gaps at the ends of the plate and ensuring that all the water flows into the water channel and is guided to the collection section, thus improving the water collection efficiency.

[0025] In one embodiment, each of the two U-shaped plates 221 has a pin seat 223 at the bottom of one end near the hinge 222, and the pin seat 223 has a socket for bolt installation.

[0026] With this design, once the water guide plate 22 is fully extended, it is secured by inserting bolts into the holes of the two pin seats 223 and tightening them, thereby locking the U-shaped plates 221 on both sides in the extended position. This prevents the water guide plate from accidentally folding due to vibration or water flow impact during use, ensuring the stability of the water guide structure.

[0027] In one embodiment, the nut 16 consists of a screwing section 161 and a retaining ring section 162 located at the top of the screwing section 161; The water guiding assembly 2 also includes an extension 23 for misaligned installation of the water guiding plate 22. The extension 23 includes a third ring 231, a fourth ring 232, a fifth ring 233, and a sixth ring 234 arranged sequentially from top to bottom. A connecting rod 235 is fixedly connected between the third ring 231 and the fourth ring 232. The third ring 231 is sleeved on the bottom second ring 212 and its inner diameter is smaller than that of the first ring 211 and the outer diameter of the retaining ring section 162. The outer diameters of the fourth ring 232 and the sixth ring 234 are both larger than that of the fifth ring 233, and the outer diameter of the fifth ring 233 is equal to that of the second ring 212.

[0028] With this design, the third ring 231 is hooked onto the second ring 212 of the mounting base 21, and the retaining ring section 162 and the first ring 211 prevent it from slipping off. The groove formed between the fourth ring 232 and the sixth ring 234 provides another engagement height, so that the water guide plate 22 installed on the extension member 23 can be arranged perpendicularly to the water guide plate 22 installed on the mounting base 21, so that multiple water guide plates 22 in the same direction can collect the water flow and discharge it into the vertically arranged water guide plate 22.

[0029] In one embodiment, the diversion section includes a three-way diversion valve, the inlet of which is connected to the outlet of the collection section. The three-way diversion valve has a first outlet and a second outlet, the first outlet being connected to the external discharge section and the second outlet being connected to the recovery filter section. The three-way diversion valve is a manual switching valve or an electric switching valve electrically connected to the controller.

[0030] This design uses a three-way diversion valve to distribute the collected water according to water quality or usage requirements. When the water quality meets the standards, it is switched to the recycling and filtration section for purification and reuse at water replenishment points such as dust suppression and equipment cooling in coal mines. When the water quality does not meet the standards or the water volume exceeds the limit, it is switched to the discharge section to discharge to a designated location. The manual or electric control mode can be flexibly selected according to the level of automation on the coal mine site to achieve the rational allocation and utilization of water resources.

[0031] It should be noted that the liquid collection section, the diversion section, the external discharge section, and the recovery filtration section are all common knowledge in this field, so their specific structural composition and working principle will not be described in detail in this article.

[0032] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are 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. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0034] Additionally, "multiple" refers to two or more.
