Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and more specifically to a filling and sealing baffle. Background Technology

[0002] In mining, filling and sealing baffles are key safety components used to close roadways, isolate goaf areas, or control mineral flow. They are usually made of metal, concrete, or composite materials. Their main functions include supporting the surrounding rock, preventing collapse, isolating hazardous areas (such as gas or dust diffusion areas), and separating the working area from the filling area in backfill mining methods to ensure the directional accumulation of tailings, cementing materials, and other filling materials.

[0003] However, while filling and sealing baffles play an important role in mining applications, they also have some potential drawbacks, especially when sealing off unused goafs or abandoned roadways. Traditional baffles rely on manual installation and have a slow response time in emergency situations (such as water inrush sealing). In addition, existing filling and sealing baffles are usually static structures, making it difficult to cope with emergencies such as sudden collapses. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a filling and sealing baffle to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a filling and sealing baffle, including a prefabricated base plate assembly, a splicing plate assembly movably connected to the top of the prefabricated base plate assembly, a threaded rod movably sleeved at the top of the splicing plate assembly, a variable pressure-bearing assembly movably sleeved on the surface of the threaded rod, auxiliary rods fixedly connected to both sides of the bottom of the variable pressure-bearing assembly, the surfaces of the auxiliary rods movably sleeved inside the splicing plate assembly, auxiliary pressure-distributing plates movably connected to both sides of the surface of the splicing plate assembly and near the top, the tops of the auxiliary pressure-distributing plates movably connected inside both ends of the variable pressure-bearing assembly. By providing the prefabricated base plate assembly and splicing plate assembly, it is beneficial to quickly assemble and seal goafs or abandoned roadways using the prefabricated base plate assembly and splicing plate assembly, reducing the steps of manual installation and saving manpower and time costs.

[0006] Furthermore, the prefabricated base plate assembly includes a main load-bearing plate, an impact-resistant plate fixedly connected to one side of the main load-bearing plate, a stable base fixedly connected to the bottom of the impact-resistant plate on the side away from the main load-bearing plate, a guide ramp provided on the side of the stable base away from the surface of the impact-resistant plate, a butt plate fixedly connected to one side of the top of the main load-bearing plate, a butt groove provided on the top of the main load-bearing plate near the butt plate, and the surface of the impact-resistant plate on the side away from the main load-bearing plate is arc-shaped. By providing the prefabricated base plate assembly and splicing plate assembly, it is beneficial to quickly assemble and seal goafs or abandoned roadways using the prefabricated base plate assembly and splicing plate assembly, reducing the steps of manual installation and saving manpower and time costs.

[0007] Furthermore, the splicing plate assembly includes a connecting baffle, an assembly plate is fixedly connected to the bottom of the connecting baffle, an assembly groove is provided on the bottom of the connecting baffle near the assembly plate, and springs are provided inside the auxiliary rods that are movably connected to the connecting baffle. Pressure sensors are fixedly connected to the bottom of each spring. By providing the prefabricated base plate assembly and splicing plate assembly, it is beneficial to quickly assemble and seal goafs or abandoned roadways using the prefabricated base plate assembly and splicing plate assembly, reducing the steps of manual installation and saving manpower and time costs.

[0008] Furthermore, a gravity sensor is fixedly connected to one side of the splicing panel assembly. The side of the gravity sensor away from the splicing panel assembly has regularly arranged warning sound holes. By incorporating a variable pressure-bearing component, it is beneficial to restrict the pressure received when a collapse occurs in the blocked abandoned tunnel. The variable pressure-bearing component moves and pushes the auxiliary pressure-distributing plates on both sides to distribute the downward pressure to both sides of the wall. At the same time, the auxiliary rod compresses the spring, so that the pressure value is transmitted to the gravity sensor in real time, and an alarm is issued to provide a warning when the pressure exceeds the threshold.

[0009] Furthermore, the prefabricated base plate assembly and splicing plate assembly are connected by interlocking plates and interlocking grooves with assembly plates and assembly grooves. By providing prefabricated base plate assemblies and splicing plate assemblies, it is beneficial to quickly assemble and seal goafs or abandoned roadways, reducing the steps of manual installation and saving manpower and time costs.

[0022] The splicing plate assembly 2 includes a connecting baffle 201, an assembly plate 202 fixedly connected to the bottom of the connecting baffle 201, an assembly groove 203 opened on the bottom of the connecting baffle 201 near the assembly plate 202, and springs 7 are opened inside the auxiliary rod 5 of the connecting baffle 201.

By providing the prefabricated base plate assembly 1 and the splicing plate assembly 2, it is convenient to quickly assemble and seal the goaf or abandoned roadway, reduce the steps of manual installation, and save manpower and time costs.

[0025] The working principle of this utility model:

[0026] Firstly, when using the sealing baffle, the prefabricated base plate assembly 1 is placed on the ground of the roadway to be sealed. Then, the assembly plate 202 and assembly groove 203 at the bottom of the connecting baffle 201 are aligned with the docking plate 106 and docking groove 105, respectively, so that the prefabricated base plate assembly 1 and the splicing plate assembly 2 are connected as a whole. Then, when a sudden water inrush occurs in the roadway, the water flow is guided by the guide ramp 104 to the top of the stable base 103, and the arc surface of the impact-resistant plate 102 guides the water flow to both sides, so that the water flow on both sides reduces the frontal impact water flow. Then, when a collapse occurs in the roadway at the top of the splicing plate assembly 2, the pressure of the collapse squeezes the variable pressure-bearing component 4, so that the variable pressure-bearing component... 4. The screw rod 3 rotates inside the connecting baffle 201. Then, the variable pressure bearing component 4 is lowered by the rotation of the screw rod 3 and drives the auxiliary rod 5 to squeeze the spring 7. The spring 7 then transmits the pressure it receives to the internal position of the gravity sensor 8 in real time. Then, the descent of the variable pressure bearing component 4 causes the auxiliary pressure distribution plate 6 to tilt to both sides of the connecting baffle 201. The pressure on the top of the variable pressure bearing component 4 is distributed by the wall support on both sides of the auxiliary pressure distribution plate 6. Then, as the pressure on the variable pressure bearing component 4 increases, the spring 7 transmits the pressure to the position of the gravity sensor 8. Then, when the threshold set by the gravity sensor 8 is exceeded, an alarm is issued through the warning sound hole 801 to remind the user.
