[0020] 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. Example 1

[0021] Please see Figure 1-5 The present invention provides the following technical solution: a coal mine water plugging material performance testing device, including a collection box 1, universal wheels 2 are provided at the four corners of the bottom of the collection box 1, a drain pipe 3 is provided on one side of the collection box 1, a water inlet square pipe 6 is provided at the top of the collection box 1, a convenient disassembly and assembly component 5 is provided inside the water inlet square pipe 6, and a positioning and installation component 4 is provided on the upper side of the collection box 1.

[0022] Specifically, the easy-to-assemble and disassemble component 5 includes an annular bracket 51, a fixing plate 52, a sealing plug 53, a limiting device 54, a square bracket 55, a splicing base 56, and a blocking device 57. Among them, a splicing base 56 is provided on one side of the inside of the water inlet square tube 6, a square bracket 55 is provided on one side of the splicing base 56, a fixing plate 52 is provided on one side of the upper end of the square bracket 55, an annular bracket 51 is provided on the upper end of the fixing plate 52, a limiting device 54 is provided inside the fixing plate 52, a sealing plug 53 is provided on one side of the fixing plate 52, and a blocking device 57 is provided on the surface of the water inlet square tube 6 corresponding to the sealing plug 53.

[0023] By adopting the above technical solution, when it is necessary to test the sealing performance of coal mine water plugging materials, the annular mounting bracket 51 or the square mounting bracket 55 can be selected and installed according to the style of the water plugging material. When it is necessary to put the water plugging material into the annular mounting bracket 51, the movable frame 542 is moved down along the movable groove 544 to move the clamping block 541. At this time, the water plugging material is clamped into the annular mounting bracket 51. Then, the movable frame 542 is released to move the clamping block 541 up and support the bottom end of the water plugging material, ensuring that it can be clamped and positioned inside the annular mounting bracket 51 to prevent loosening and falling, ensuring the stability of equipment use and improving the performance testing effect. Similarly, the water plugging material can also be put into the square mounting bracket 55 for use to ensure the applicability of the equipment.

[0024] Specifically, the limiting device 54 includes a clamping block 541, a movable frame 542, an intermediate plate 543, a movable groove 544, a fixed rod 545, an abutment block 546, and a limiting spring 547. The fixed plate 52 has symmetrically opened movable grooves 544 inside, and an intermediate plate 543 is set in the middle of the movable groove 544. The fixed rod 545 passes through the middle plate 543. The limiting spring 547 is symmetrically sleeved on the surface of the fixed rod 545. The abutment block 546 is set at the bottom end of the limiting spring 547. The movable frame 542 is set at the upper end of the limiting spring 547. The clamping block 541 is set at the upper end of the movable frame 542.

[0025] By adopting the above technical solution, when the water-blocking material is loaded into the annular retainer 51, the movable frame 542 moves down along the movable groove 544, causing the clamping block 541 to move. At this time, the water-blocking material is clamped into the annular retainer 51. Then, the movable frame 542 is released, causing the clamping block 541 to move up and support the bottom end of the water-blocking material, ensuring that it can be clamped and positioned inside the annular retainer 51, preventing it from loosening and falling off, ensuring the stability of the equipment and improving the performance testing effect.

[0026] Specifically, the annular card holder 51 has a positioning groove inside corresponding to the clamping block 541, and the clamping block 541 fits against the inner wall of the positioning groove.

[0027] By adopting the above technical solution, the strength of the clamping block 541 is guaranteed, and the stability of the water-blocking material is improved.

[0028] Specifically, the blocking device 57 includes a limiting baffle 571, a positioning hole 572, a guide rod 573, a positioning spring 574, a pull rod 575, a support frame 576, and a positioning block 577. A damping shaft 578 is provided on one side of the water inlet square tube 6. The surface of the damping shaft 578 is provided with a limiting baffle 571. The bottom end of the limiting baffle 571 is provided with a positioning hole 572. A support frame 576 is provided at the bottom end of one side of the water inlet square tube 6. Guide rods 573 are symmetrically arranged inside the support frame 576. A positioning spring 574 is provided on the surface of the guide rod 573. A positioning block 577 is provided at one end of the positioning spring 574. A support frame 576 is provided on one side of the bottom end of the positioning block 577.

[0029] By adopting the above technical solution, the fixing plate 52 is inserted into the interior of the water inlet square pipe 6, so that the other half of the water-blocking material enters the interior of the splicing seat 56 for positioning. At this time, the sealing plug 53 can block the opening of the water inlet square pipe 6. Then, the limiting baffle 571 is rotated along the damping shaft 578 to move it downward. The limiting baffle 571 abuts against one side of the positioning block 577 and makes it slide along the guide rod 573 under force, which makes the positioning spring 574 stretched under force. When the positioning hole 572 corresponds to the positioning block 577, the positioning spring 574 resets and drives the positioning block 577 to be inserted into the positioning hole 572 to limit the limiting baffle 571, ensuring that the limiting baffle 571 can block the sealing plug 53, preventing loosening or leakage, and improving the stability of the equipment.

[0030] In this embodiment, when it is necessary to test the sealing performance of the coal mine water-blocking material, the ring-shaped bracket 51 or the square bracket 55 is selected according to the style of the water-blocking material for installation. When it is necessary to put the water-blocking material into the ring-shaped bracket 51, the movable frame 542 is moved down along the movable groove 544 to move the clamping block 541. At this time, the water-blocking material is clamped into the ring-shaped bracket 51. Then the movable frame 542 is released to move the clamping block 541 up and support the bottom end of the water-blocking material, ensuring that it can be clamped and positioned inside the ring-shaped bracket 51 to prevent loosening and falling, ensuring the stability of the equipment and improving the performance testing effect. Similarly, the water-blocking material can also be put into the square bracket 55 for use to ensure the applicability of the equipment.

[0031] Then, the fixing plate 52 is inserted into the inside of the water inlet square pipe 6, so that the other half of the water-blocking material enters the inside of the splicing seat 56 for positioning. At this time, the sealing plug 53 can block the opening of the water inlet square pipe 6. Then, the limiting baffle 571 is rotated along the damping shaft 578 to move it down. The limiting baffle 571 abuts against one side of the positioning block 577 and makes it slide along the guide rod 573 under force, which makes the positioning spring 574 stretch under force. When the positioning hole 572 corresponds to the positioning block 577, the positioning spring 574 resets and drives the positioning block 577 to be inserted into the positioning hole 572 to limit the limiting baffle 571, ensuring that the limiting baffle 571 can block the sealing plug 53, preventing loosening or leakage, and improving the stability of the equipment. Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the positioning and mounting assembly 4 includes a slider 41, a slide rail 42, a mounting block 43, a movable seat 44, a compression spring 45, a positioning rod 46, a clamping block 47, and a connecting shaft 48. The upper end of the collection box 1 is provided with a slide rail 42 on all four sides. The slider 41 is provided inside the slide rail 42. The mounting block 43 is provided on one side of the slider 41. The connecting shaft 48 is provided inside the mounting block 43. The movable seat 44 is provided on one side of the connecting shaft 48. The positioning rod 46 is symmetrically arranged inside the movable seat 44. The compression spring 45 is sleeved on the surface of the positioning rod 46. The clamping block 47 is provided at one end of the compression spring 45.

[0033] In this embodiment, when the device needs to be moved to a designated location, the collection box 1 is moved by rotating the casters 2. After moving to the designated location, the position of the mounting block 43 can be adjusted by moving the slider 41 along the slide rail 42. Then, the movable seat 44 is rotated along the connecting shaft 48, and the clamping block 47 is pulled to compress the compression spring 45. The clamping block 47 then holds the device in place at the bracket at the designated location to prevent the collection box 1 from slipping and to ensure the stability of the device.

[0034] The structure and operating principle of the collection box 1 and the water inlet square tube 6 in this utility model have been disclosed in a coal mine water plugging material performance testing device disclosed in Chinese patent application number 202321374665.X.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to test the sealing performance of coal mine water-blocking materials, the annular bracket 51 or the square bracket 55 is selected according to the style of the water-blocking material for installation. When it is necessary to put the water-blocking material into the annular bracket 51, the movable frame 542 is moved down along the movable groove 544 to move the clamping block 541. At this time, the water-blocking material is clamped into the annular bracket 51. Then, the movable frame 542 is released to move the clamping block 541 up and support the bottom end of the water-blocking material, ensuring that it can be clamped and positioned inside the annular bracket 51 to prevent loosening and falling, ensuring the stability of the equipment and improving the performance testing effect. Similarly, the water-blocking material can also be put into the square bracket 55 for use to ensure the applicability of the equipment.

[0036] Then, the fixing plate 52 is inserted into the inside of the water inlet square pipe 6, so that the other half of the water-blocking material enters the inside of the splicing seat 56 for positioning. At this time, the sealing plug 53 can block the opening of the water inlet square pipe 6. Then, the limiting baffle 571 is rotated along the damping shaft 578 to move it down. The limiting baffle 571 abuts against one side of the positioning block 577 and makes it slide along the guide rod 573 under force, which makes the positioning spring 574 stretch under force. When the positioning hole 572 corresponds to the positioning block 577, the positioning spring 574 resets and drives the positioning block 577 to be inserted into the positioning hole 572 to limit the limiting baffle 571, ensuring that the limiting baffle 571 can block the sealing plug 53, preventing loosening or leakage, and improving the stability of the equipment.

[0037] When the device needs to be moved to a designated location, push the collection box 1 to rotate via the casters 2. After moving to the designated location, move the slider 41 along the slide rail 42 to adjust the position of the mounting block 43. Then rotate the movable seat 44 along the connecting shaft 48 and pull the clamping block 47 to compress the pressure spring 45. Then, clamp the device at the bracket at the designated location via the clamping block 47 to prevent the collection box 1 from slipping and ensure the stability of the device.
