Description

Technical Field

[0001] This utility model relates to the field of underground filling technology, specifically a small gate for drainage during underground filling in mines. Background Technology

[0002] With the increasing depth of mining and the growing awareness of environmental protection, backfilling and filling of mining areas are receiving more and more attention and application in mining enterprises, and there is a trend of further development and expansion. In order to remove formwork and retaining wall water seepage, small holes need to be left in an area about 90 centimeters above the bottom of the retaining wall during the construction of the backfilling retaining wall. In the area with small holes, small gates that can effectively drain water need to be made to ensure the smooth drainage of water accumulated in the backfilling void. Currently, the wooden small gates have disadvantages such as being damaged by the shock wave of underground blasting, poor drainage efficiency, and non-reusability, and there is room for improvement.

[0003] Publication No. CN220226972U discloses a mine backfill retaining wall. By setting up connecting frames, mine waste rock can be placed inside, which greatly saves the raw material cost of the retaining wall and improves the utilization rate of mine waste rock, realizing the recycling of mine resources. By stacking several connecting frames, the height of the retaining wall can also be flexibly adjusted. By setting up a drainage mechanism, the channels for the outward discharge of slurry moisture in the goaf are increased, ensuring that the slurry moisture in the goaf can be discharged in a timely manner, enhancing the permeability of the retaining wall, and improving the setting speed and setting quality of the backfill slurry. However, this patent still has the following problems in actual use:

[0004] Although the mine's backfill retaining wall increases the channels for the outflow of slurry moisture in the goaf by setting up a drainage mechanism, ensuring that the slurry moisture in the goaf can be discharged in a timely manner, enhancing the permeability of the retaining wall, and improving the setting speed and quality of the backfill slurry, the drainage efficiency of the drainage mechanism is low, and the drainage mechanism cannot be reused. The existing technology uses drainage gates for drainage, but most of the drainage gates are made of wood. Although the cost is low, the drainage outlets are easily corroded, and the drainage gates cannot be reused, resulting in material waste.

[0005] Therefore, a small gate for filling and draining underground mines was proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage gate for underground filling in mines, so as to solve the problems of low drainage efficiency and inability to reuse the drainage mechanism mentioned in the background art. In the prior art, drainage gates are used for drainage, but most drainage gates are made of wood. Although the cost is low, the drainage outlet is easily corroded. At the same time, the drainage gates cannot be reused, resulting in material waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a small gate for filling and draining in underground mines, including a drainage mechanism and a rotating baffle installed on the outside of the drainage mechanism;

[0008] The drainage mechanism is provided with an installation mechanism on its inner side, and clamping connecting plates are provided on both sides of the installation mechanism.

[0015] Preferably, the mounting mechanism includes a mounting bracket, the mounting bracket has a fixing bolt threaded around its interior, a through groove is formed at the center of the mounting bracket, and a locking groove is formed on the outer side of the mounting bracket near the through groove.

[0016] Preferably, the mounting bracket is engaged with the reinforcing mesh plate via a locking groove, and the mounting bracket has symmetrical clamping grooves on both sides near the through groove, with a clamping sliding rod fixedly installed inside the clamping groove.

The clamping spring is slidably connected to the clamping sliding rod, and the clamping spring is fixedly installed on one side of the inside of the clamping groove.

[0018] Preferably, the clamping connecting plate is fixedly installed on the outside of the clamping sliding sleeve, and a clamping block is fixedly installed on one side of the clamping connecting plate. The clamping block is engaged with the drainage gate body through a mounting slot.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This underground mine filling drainage gate, by setting water-permeable holes, can quickly drain the filling material in the mine, allowing the filling material to quickly solidify and harden. By rotating the handle, the rotating connecting rod is moved. Since the rotating connecting rod is rotatably connected to the rotating baffle, and under the action of the rotating shaft, the rotating baffle rotates, which can block the water-permeable holes and prevent grout leakage. Through the feature of the sliding connection between the clamping sliding rod and the clamping sliding sleeve inside the clamping groove, and under the elastic force of the clamping spring, the clamping block at the end of the clamping connecting plate is engaged with the installation slot, which facilitates the installation and disassembly of the drainage gate body. The specific details are as follows:

[0020] 1. By setting up a drainage mechanism, the drainage gate body can be processed using the reinforcing mesh plate on the back, thereby improving its service life. The permeable holes allow for rapid drainage of the mine filling material, enabling it to solidify and harden quickly. Rotating the handle moves the rotating connecting rod, which is rotatably connected to the rotating baffle. Under the action of the rotating shaft, the baffle rotates, sealing the permeable holes and preventing leakage and material waste. The locking pin at the bottom of the rotating rod engages with the rotating connecting rod, securing the rod and baffle and improving the baffle's sealing effect. Since the drainage gate body and reinforcing mesh plate are made of stainless steel, they are protected against damage from underground blasting shock waves, further extending the drainage gate's service life.

By setting up an installation mechanism, not only can the mounting bracket be stably installed using fixing bolts, but the through groove inside the mounting bracket facilitates drainage, and the snap-fit ​​groove facilitates the positioning and installation of the reinforced mesh plate, thereby improving the installation efficiency of the drainage gate body. Through the feature of the sliding connection between the clamping sliding rod and the clamping sliding sleeve inside the clamping groove, and under the elastic force of the clamping spring, the clamping block at the end of the clamping connecting plate is snapped into the mounting slot, which facilitates the installation and disassembly of the drainage gate body.

The drainage mechanism 1 includes a drainage gate body 101, a reinforcing mesh plate 102 is fixedly installed on the back of the drainage gate body 101, and symmetrical installation slots 103 are provided on both sides of the drainage gate body 101. The drainage gate body 101 has several water-permeable holes 104 inside. A rotating shaft 105 is rotatably connected to the side of the door body 101 near the water permeable hole 104. A rotating baffle 106 is fixedly installed on the outside of the rotating shaft 105. A rotating connecting rod 107 is rotatably connected to the outside of the rotating baffle 106. A rotating handle 108 is fixedly installed at the center of the outside of the rotating connecting rod 107. Support blocks 109 are symmetrically installed on the top of the drainage door body 101 near the top of the rotating connecting rod 107. A rotating support 110 is fixedly installed on the outside of the support block 109. A locking rotating rod 111 is rotatably connected to the bottom of the rotating support 110 to lock the rotation. An inclined locking pin 112 is fixedly installed on the inner bottom of the rod 111. The inclined locking pin 112 is engaged with the rotating connecting rod 107. The drainage gate body 101 is processed by the reinforcing mesh plate 102 on the back of the drainage gate body 101, thereby improving the service life of the drainage gate body 101. By setting the water permeable hole 104, the backfill material in the mine can be drained quickly, so that the backfill material can be quickly solidified and hardened. The rotating connecting rod 107 is moved by rotating the handle 108. Since the rotating connecting rod 107 is rotatably connected to the rotating baffle 106 and is on the rotating shaft 10 Under the action of 5, the rotating baffle 106 rotates, which can block the water permeable hole 104 and prevent grout leakage, thus avoiding material waste.

Since the drainage gate body 101 and the reinforcing mesh plate 102 are made of stainless steel, they can prevent damage from the shock wave of underground blasting and improve the service life of the drainage gate body 101.

[0031] The mounting mechanism 2 includes a mounting bracket 201. The mounting bracket 201 has threaded fixing bolts 202 connected to its inner perimeter. A through groove 203 is formed at the center of the mounting bracket 201. A locking groove 204 is formed on the outer side of the mounting bracket 201 near the through groove 203. The mounting bracket 201 is locked to the reinforcing mesh plate 102 via the locking groove 204. The mounting bracket 201 has symmetrically formed clamping grooves 205 on both sides near the through groove 203. A clamping sliding rod 206 is fixedly installed inside the clamping groove 205. A clamping sliding sleeve 207 is slidably connected to the outer side of the clamping sliding rod 206. A clamping spring 208 is fixedly installed on one side of the clamping sliding sleeve 207. The clamping spring 208 is slidably connected to the clamping sliding rod 206 and is fixedly installed inside the clamping groove 205. The connecting plate 209 is fixedly installed on the outside of the clamping sliding sleeve 207. A clamping block 210 is fixedly installed on one side of the clamping connecting plate 209. The clamping block 210 is engaged with the drainage gate body 101 through the mounting slot 103. The mounting bracket 201 is stably installed using the fixing bolts 202. At the same time, the through groove 203 inside the mounting bracket 201 facilitates drainage, and the engaging groove 204 facilitates the positioning and installation of the reinforced mesh plate 102, thereby improving the installation efficiency of the drainage gate body 101. The clamping sliding rod 206 inside the clamping sliding groove 205 is slidably connected to the clamping sliding sleeve 207. Under the elastic force of the clamping spring 208, the clamping block 210 at the end of the clamping connecting plate 209 is engaged with the mounting slot 103, which facilitates the installation and disassembly of the drainage gate body 101.

[0032] Working principle: Before using this type of mine underground filling and drainage gate, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, firstly, the mounting bracket 201 is stably installed using fixing bolts 202. Simultaneously, the through groove 203 inside the mounting bracket 201 facilitates drainage, and the engaging groove 204 facilitates the positioning and installation of the reinforcing mesh plate 102, thereby improving the installation efficiency of the drainage gate body 101. The clamping sliding rod 206 inside the clamping groove 205 is slidably connected to the clamping sliding sleeve 207, and under the elastic force of the clamping spring 208, the clamping block 210 at the end of the clamping connecting plate 209 engages with the mounting groove 103, facilitating the installation and disassembly of the drainage gate body 101. Secondly, the reinforcing mesh plate 102 on the back of the drainage gate body 101 is used to process the drainage gate body 101, thereby improving its service life. This is achieved by setting water permeable holes 104. It can quickly drain the backfill material in the mine, allowing the backfill to solidify and harden rapidly. By rotating the handle 108, the rotating connecting rod 107 can be moved. Since the rotating connecting rod 107 is rotatably connected to the rotating baffle 106, and under the action of the rotating shaft 105, the rotating baffle 106 can rotate, which can seal the water hole 104 and prevent grout leakage, thus avoiding material waste. The locking pin 112 at the bottom of the locking rotating rod 111 engages with the rotating connecting rod 107, which can fix the rotating connecting rod 107 and the rotating baffle 106, improving the sealing effect of the rotating baffle 106. Since the drainage gate body 101 and the reinforcing mesh plate 102 are made of stainless steel, they can prevent damage from underground blast shock waves and improve the service life of the drainage gate body 101.
