Abstract
Description
Technical Field
[0001] This invention relates to the field of coal mine grouting technology, specifically to an improved power and water supply method based on coal mine grouting and its water storage device. Background Technology
[0002] Grouting is a widely used reinforcement construction technique in buildings, bridges, and other structures, which can improve the strength, stability, and durability of the structure. A stable water and power supply is one of the key factors in ensuring the quality of grouting construction. For water storage in grouting projects, common water storage devices such as water tanks are generally used.
[0003] However, the water storage device for this grouting project has the following defects in actual use: 1. Existing grouting engineering water storage devices, when transporting stored water to the water supply pipe for grouting operations, often contain a high level of impurities because the water source is the water transport pipeline, including but not limited to: water from underground tunnels, rivers, etc. This can easily lead to blockages in the grouting equipment when the stored water is transferred. Furthermore, the large amount of impurities and floating matter in the water can easily accumulate inside the water storage device, making cleaning inconvenient. 2. Existing water storage devices for grouting projects are generally assembled using integrated machining or bolting methods, and the water content stored inside is relatively fixed. However, in actual operation of grouting projects, due to varying workloads, the water storage capacity of traditional grouting project water storage devices (containers) is difficult to precisely match the water supply volume. Therefore, multiple containers are often required, resulting in high cost and large footprint. Furthermore, the conveying pipes for different water storage devices (containers) need to be disassembled and installed, leading to low efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide an improved power and water supply method and its water storage device based on coal mine grouting, so as to solve the problems mentioned in the background art.

S2. Water Supply System Design: The water supply system mainly consists of water source transmission pipelines, water storage equipment, water supply network and water supply control system. According to the layout and needs of the construction site, a reasonable water supply network is designed to ensure that the water source can cover the entire construction area. A water supply control system is installed to realize the regulation and control of the water supply. S3. Power supply method selection: The power supply method of direct current is adopted, with the filter pipe as the cathode and the grouting pipe as the anode. The direct current discharge method promotes electro-osmotic drainage and chemical grout infiltration, forming an electro-osmotic effect, reducing the soil moisture content and forming a grout infiltration path. S4. Power supply system design: A direct-through drilling technique is applied to the grouting site to lay a high-voltage cable from the underground mining area substation to directly supply power to the transformer at the grouting site, thus meeting the power supply requirements.

The bottom and inner wall of the upper blocking cover have sufficient gaps with the outer wall of the upper pipeline, and the rotating assembly block is installed on the outside of the quick-release drive assembly.
[0011] As a preferred embodiment of the present invention, the quick-release drive assembly includes: an upper base mounted at the center of the top of the upper tank; a servo drive source mounted on the top of the upper base; a main shaft connected to the output end of the servo drive source and extending into the interior of the upper tank; an intermediate shaft mounted on the outer side of the bottom of the main shaft via a positioning pin; and a lower shaft mounted on the outer side of the bottom of the intermediate shaft via a positioning pin. A one-way ratchet is installed and fixed on the outer side of the bottom of the lower shaft.
[0012] In a preferred embodiment of the present invention, multiple intermediate shafts are provided, and the multiple intermediate shafts are fixed together by positioning pins. An inner wall cleaning assembly is installed on the outer side of the main shaft and the intermediate shafts.

The annular toothed plate is located on the outside of the movable disc, and the bottom scraper bar cleans the inner bottom of the lower tank through its outer scraping portion.
[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the improved power and water supply method and water storage device based on coal mine grouting, the output shaft is driven by a servo drive source to rotate in both forward and reverse directions. When separating impurities in the grouting water, the main shaft, intermediate shaft, and lower shaft can be activated in reverse to drive the inner wall cleaning scraper and isolation plate to rotate continuously, allowing impurities and suspended solids in the grouting water to move and improving the separation effect. When the servo drive source drives the main shaft, intermediate shaft, and lower shaft connected to the output end to rotate in the forward direction, in addition to rotating the inner wall cleaning scraper and isolation plate, multiple bottom sweeping rods can also be driven to rotate vertically and horizontally through a one-way ratchet and one-way stop connection to treat impurities on the inner wall and bottom of the water storage tank, minimizing the time required for subsequent disassembly and cleaning of the water storage tank. In this design, the bottom scraper bar will not rotate when the lower shaft rotates in the reverse direction. This effectively avoids the problem of particulate impurities settled at the bottom of the water storage tank becoming active due to rotational force, and prevents particulate impurities from entering the grouting equipment. 2. In the improved power and water supply method and its water storage device based on coal mine grouting, the sliding connection between the upper inclined rod and the inclined slide rod, the lower inclined rod and the inclined slider, and the rotating connection between the inclined slide rod and the inclined slider ensure that when the main shaft and the intermediate shaft rotate, the centrifugal force generated by the rotation drives the upper inclined rod, the lower inclined rod, and the inner wall cleaning scraper connected by the connecting block on the outside of the main shaft and the intermediate shaft to move, generating vortices of different diameters, reducing the probability of impurities and suspended solids in the water sticking together. Furthermore, the triangular structure formed between the upper and lower inclined rods ensures the overall strength, making the device less prone to damage or even breakage due to the tensile force generated by centrifugal force, thus ensuring high safety. 3. In the improved power and water supply method and its water storage device based on coal mine grouting, by partially installing a centralized box at the bottom edge of the isolation plate, impurities and suspended solids that move to the edge of the isolation plate by centrifugal force and fall naturally into the centralized box can be automatically recovered. This minimizes the time required to clean the isolation plate later. Furthermore, the design of the water storage tank structure allows for the easy assembly of water storage tanks of different heights and capacities, based on site conditions and the size of the suitable construction area, effectively reducing the cost of the water storage device. 4. In the improved power and water supply system and its water storage device based on coal mine grouting, the power supply technology meets the power supply needs of the grouting port, solves the environmental pollution and frequent maintenance problems caused by using generators at the grouting port, and also solves the problems of cost associated with using diesel generators and safety hazards caused by frequent uphill maintenance. The water supply technology solves the problem of insufficient water supply at the discharge port, saves transportation costs, eliminates transportation risks, solves the costs associated with water truck transportation, and eliminates safety hazards.

[0020] Example 1
[0021] Please see Figures 1-12 An improved power and water supply method based on coal mine grouting includes the following steps: S1. Water supply method selection: During the grouting construction, a water storage device is used to provide a stable water supply to meet the needs of the grouting operation. The water storage device is equipped with an impurity cleaning structure to prevent harmful substances from being mixed in and having an adverse effect on the construction materials and structures. S2. Water Supply System Design: The water supply system mainly consists of water source transmission pipelines, water storage equipment, water supply network and water supply control system. According to the layout and needs of the construction site, a reasonable water supply network is designed to ensure that the water source can cover the entire construction area. A water supply control system is installed to realize the regulation and control of the water supply. S3. Power supply method selection: The power supply method of direct current is adopted, with the filter pipe as the cathode and the grouting pipe as the anode. The direct current discharge method promotes electro-osmotic drainage and chemical grout infiltration, forming an electro-osmotic effect, reducing the soil moisture content and forming a grout infiltration path. S4. Power supply system design: A direct-through drilling technique is applied to the grouting site to lay a high-voltage cable from the underground mining area substation to directly supply power to the transformer at the grouting site, thus meeting the power supply requirements.
[0022] Example 2
[0023] Please see Figures 1-12A water storage device based on coal mine grouting includes a water storage tank 10; a screen structure 20 disposed inside the water storage tank 10; an impurity isolation component 30 disposed at the bottom of the screen structure 20 and located inside the water storage tank 10; and a cleaning and impurity removal structure 40 disposed inside the water storage tank 10 and penetrating the screen structure 20 and the impurity isolation component 30. The cleaning and impurity removal structure 40 includes: a quick-release drive component 401 disposed at the center inside the water storage tank 10; an inner wall cleaning component 402 installed outside the quick-release drive component 401 and located above the screen structure 20 and the impurity isolation component 30; a movable disk 403 movably disposed at the bottom of the quick-release drive component 401 and rotatably connected to the bottom of the water storage tank 10; a one-way ratchet 404 rotatably connected to the top of the movable disk 403 and installed outside the bottom of the quick-release drive component 401; and a one-way scraping component 405 connected to the outside of the one-way ratchet 404 and movably disposed outside the movable disk 403.
[0024] The working principle described above is as follows: When water used for coal mine grouting enters the water storage tank 10, the screen structure 20 and impurity isolation component 30 installed inside the tank 10 can separate a large number of impurities and suspended solids, ensuring that the water delivered to the bottom of the tank 10 and to the grouting equipment does not contain a large number of impurities. Furthermore, the design of the water storage tank 10, compared to traditional water storage containers, allows for selection of its internal capacity based on requirements. In practical use, a water storage tank 10 suitable for the corresponding site space can be selected and installed with minimal cost. Additionally, when treating impurities in the water source, the quick-release drive component 401 can be activated by rotating in reverse, activating the inner wall cleaning component 402 and the impurity isolation component 30 to rotate, increasing the activity of impurities in the water and improving the separation effect. When it is necessary to clean the inner wall of the water storage tank 10, the quick-release drive assembly 401 can be activated to rotate in the forward direction, which simultaneously drives the inner wall cleaning assembly 402, the impurity isolation assembly 30 and the one-way scraping assembly 405 to operate, effectively cleaning the inner wall and bottom of the water storage tank 10, minimizing the time required for subsequent disassembly and cleaning of the water storage tank 10.
[0025] For details, please refer to the following: Figure 4 The water storage tank 10 consists of an upper tank 101 at the top, an assembly tank 102 in the middle, and a lower tank 103 at the bottom. Multiple assembly tanks 102 are provided. An external embedded part 1021 is installed on the outer side of the top of multiple assembly tanks 102. An inlay protrusion 1022 is installed at the eccentric part of the bottom of multiple assembly tanks 102. The inlay protrusion 1022 matches the external embedded part 1021. The inlay protrusion 1022 is installed at the bottom of the upper tank 101, and the external embedded part 1021 is installed on the outer side of the top of the lower tank 103.
[0026] In this design, a screen structure 20 is installed inside the assembly tank 102, and an inner wall cleaning component 402 is movably installed inside the upper tank 101 and the lower tank 103. An impurity isolation component 30 is installed at the inner top of the lower tank 103, and a movable disc 403 is rotatably connected to the inner bottom of the lower tank 103. The upper tank 101 has input pipes 1011 connected to both sides of the top, and an output pipe 1031 connected to one side of the bottom.
[0027] In the water storage device based on coal mine grouting of the present invention, multiple assembly tanks 102 can be assembled according to actual conditions by connecting the external embedded part 1021 and the inlaid protrusion 1022 (by screws or sealing strips) to meet different assembly and use requirements.
[0028] For details, please refer to the following: Figure 5 The screen structure 20 includes: a support body 201 installed inside the assembly tank 102; and screening screens 202 arranged on the left and right sides inside the support body 201. A quick-release drive assembly 401 is provided through the center of the support body 201, and the mesh size of the screening screen 202 at the top is larger than that at the bottom.
[0029] In the water storage device based on coal mine grouting of the present invention, the design of two screening screens 202 with different mesh sizes can improve the separation effect of impurities and suspended solids in the water.
[0030] For details, please refer to the following: Figure 9 and Figure 10 The impurity isolation assembly 30 includes: an isolation plate 301 installed at the top of the lower tank 103; an upper pipe 302 opened at the eccentric position at the top of the isolation plate 301; a rotating assembly block 303 installed at the center inside the isolation plate 301; an upper bracket 304 installed at the top inside the upper pipe 302; a threaded positioning rod 305 threadedly connected to the center inside the upper bracket 304; and an upper blocking cover 306 rotatably connected to the outside of the top of the threaded positioning rod 305 and positioned above the upper pipe 302. The bottom and inner wall of the upper blocking cover 306 have sufficient gaps with the outer wall of the upper pipe 302. The rotating assembly block 303 is installed on the outside of the quick-release drive assembly 401.
[0031] In the water storage device based on coal mine grouting of the present invention, when water enters the top of the isolation plate 301, impurities in the water will adhere to the top of the isolation plate 301 due to their weight and be located on the outside of the upper pipe 302. When the water at the top of the isolation plate 301 exceeds the upper pipe 302, the water will move through the channel between the outside of the upper pipe 302 and the inner wall of the upper baffle 306 to the inside of the upper pipe 302, and then be transmitted through the upper pipe 302 to the space at the bottom of the isolation plate 301, thereby achieving the separation of some impurities in the water. The threaded positioning rod 305 is designed to adjust the distance between the top of the upper pipe 302 and the bottom of the upper baffle 306.
[0032] For details, please refer to the following: Figure 6 and Figure 7 The quick-release drive assembly 401 includes: an upper base 4011 mounted at the top center of the upper tank 101; a servo drive source 4012 mounted on the top of the upper base 4011; a main shaft 4013 connected to the output end of the servo drive source 4012 and extending into the interior of the upper tank 101; an intermediate shaft 4014 mounted on the outer side of the bottom of the main shaft 4013 via a positioning pin 40131; and a lower shaft 4015 mounted on the outer side of the bottom of the intermediate shaft 4014 via a positioning pin 40131, wherein a one-way ratchet 404 is mounted and fixed on the outer side of the bottom of the lower shaft 4015.
[0033] In this solution, multiple intermediate shafts 4014 are provided, and the multiple intermediate shafts 4014 are fixed together by positioning pins 40131. The outer side of the main shaft 4013 and the intermediate shafts 4014 are equipped with an inner wall cleaning component 402. The intermediate shaft 4014 is provided through the support body 201, and the outer side of the lower shaft 4015 is equipped with a rotating assembly block 303.
[0034] In the coal mine grouting-based water storage device of the present invention, when assembling different numbers of assembly tanks 102, multiple intermediate shafts 4014 of corresponding lengths can be assembled and fixed by positioning pins 40131 to meet the needs of water storage tanks 10 with different capacities. During impurity separation and cleaning, the servo drive source 4012 can be activated to rotate the main shaft 4013, intermediate shaft 4014, and lower shaft 4015 connected to the output end of the servo drive source 4012, thereby driving multiple structures mounted on the outer side of the main shaft 4013, intermediate shaft 4014, and lower shaft 4015 to operate. When the lower shaft 4015 rotates, it drives the one-way ratchet 404 mounted on its bottom outer side to rotate. The forward and reverse rotation of the one-way ratchet 404 selectively drives the one-way scraping assembly 405 to operate.
[0035] For details, please refer to the following: Figure 7 and Figure 8The inner wall cleaning assembly 402 includes: a connecting block 4021 installed on the outside of the main shaft 4013; an upper inclined rod 4022 rotatably connected inside the connecting block 4021; an inclined slide rod 4023 slidably connected inside the upper inclined rod 4022 and extending to the outside; a lower inclined rod 4024 rotatably connected inside the connecting block 4021 and located at the bottom of the upper inclined rod 4022; an inclined slider 4025 slidably connected inside the lower inclined rod 4024; and an inner wall cleaning scraper 4026 installed on the side of the lower inclined rod 4024 by screws. The top of the inclined slider 4025 is rotatably connected to the inclined slide rod 4023, and the inner wall cleaning scraper 4026 cleans the inner wall of the assembled tank 102 through the scraping part on the outside.
[0036] In the water storage device based on coal mine grouting of the present invention, when the main shaft 4013 rotates, the upper inclined rod 4022 and the lower inclined rod 4024, which are installed on its outer side via the connecting block 4021, will drive the inner wall cleaning scraper 4026 to rotate, cleaning the inner wall of the assembly tank 102 that is in contact with the side of the inner wall cleaning scraper 4026. At the same time, the rotation of the upper inclined rod 4022 and the lower inclined rod 4024 will also drive the water set on its outer side to move and agitate, improving the effect of separating impurities and suspended solids in the water. Among them, the centrifugal force generated by the rotation can make the inclined slide rod 4023 and the inclined slider 4025 respectively positioned in corresponding positions inside the upper inclined rod 4022 and the lower inclined rod 4024, and the triangular structure of the upper inclined rod 4022 and the lower inclined rod 4024 ensures the strength and service life of the upper inclined rod 4022 and the lower inclined rod 4024.
[0037] For details, please refer to the following: Figure 10 , Figure 11 and Figure 12 The one-way scraping assembly 405 includes: a one-way stop 4051 slidably connected to the inner wall of the movable disk 403 and abutting against the side of the one-way ratchet 404; a spring 4052 connected between the bottom of the one-way stop 4051 and the inner wall of the movable disk 403; a connector 4053 rotatably connected to the outside of the movable disk 403; a transmission gear 4054 installed on the outside of the connector 4053; a bottom scraping bar 4055 connected to the side of the connector 4053; and an annular toothed plate 4056 meshing with the bottom of the transmission gear 4054 and installed on the inner bottom of the lower tank 103, wherein the annular toothed plate 4056 is located on the outside of the movable disk 403, and the bottom scraping bar 4055 cleans the inner bottom of the lower tank 103 through the scraping part on the outside.
[0038] In the water storage device based on coal mine grouting of the present invention, when the one-way ratchet 404 rotates in the reverse direction, the inclined portion of its teeth abuts against the inclined portion of the one-way stop 4051, compressing the spring 4052 connected to the bottom of the one-way stop 4051. That is, the rotation of the one-way ratchet 404 will not drive the movable disk 403 to rotate. When the one-way ratchet 404 rotates in the forward direction, the vertical portion of its teeth abuts against the vertical surface of the one-way stop 4051, driving the movable disk 403 connected to the one-way stop 4051 to rotate. When the movable disk 403 rotates, the connector 4053 and the transmission gear 4054 installed on its outer side will rotate, and through the meshing connection between the transmission gear 4054 and the bottom annular toothed plate 4056, the connector 4053 and the bottom scraper 4055 will rotate horizontally, maximizing the cleaning effect on the bottom of the lower tank 103.
[0039] Example 3
[0040] In practical use, it was found that when the top of the isolation plate 301 of the rotating device isolates some impurities through the structure of the upper pipe 302, most of the impurities will accumulate at the edge of the isolation plate 301 due to the centrifugal force generated by the rotation. These impurities can easily enter the bottom of the lower tank 103 through the gap between the isolation plate 301 and the inner wall of the lower tank 103, affecting the separation effect. At the same time, the impurities located at the top of the isolation plate 301 will move to various positions on the isolation plate 301 when the device is not operating, making it inconvenient to clean the impurities from the isolation plate 301 later.
[0041] For specific reference Figure 13 and Figure 14 A lower groove 50 is provided at the inner edge of the isolation plate 301, and a collection box 501 installed on the inner wall of the lower tank 103 is rotatably connected below the lower groove 50. Multiple liquid passage holes 502 are provided at the bottom of the collection box 501. Both the collection box 501 and the lower groove 50 are located on the outside of the upper pipeline 302.
[0042] In the water storage device based on coal mine grouting of the present invention, when the isolation plate 301 rotates, centrifugal force is generated, which drives the impurities and suspended matter on the top of the isolation plate 301 to move outward, so that the impurities can move through the lower groove 50 to the interior of the collection box 501, and through the depth of the interior of the collection box 501, the impurities inside the collection box 501 are centrally stored. The liquid passage 502 opened at the bottom of the collection box 501 can guide the water flow and intercept impurities.
[0043] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
