[0002] With the improvement of the mechanization and intelligence level of coal mine equipment, the production capacity of coal mines has been greatly improved, so more and more dust is generated in coal mines, especially in mine tunnels. Since workers need to walk back and forth, if dust removal is not carried out in time, it will not only affect the operating line of sight, but also cause the dust concentration to exceed the standard, which has caused great safety hazards to the safe production of coal mines. In order to reduce the generation and spread of dust in coal mine work and protect the health and safety of miners, the existing technology uses dust catching nets and wind flow purification water curtains to effectively install and use them to intercept dust and reduce dust. However, the existing operation method is to customize the corresponding frame and dust catching net according to the shape of the gate-type mine hole. However, due to the irregular shape of the mine hole at the installation location, the customized frame often adjusts the position appropriately, resulting in errors in the installation of the dust catching net, resulting in inadequate installation. The dust catching net can only be cut and then fixed with rivets or welding, which makes the installation of the dust catching net have great loopholes, resulting in unsatisfactory dust prevention effect. It cannot be installed according to the existing frame structure, and there are great difficulties during installation, which has certain difficulties. Utility Model Content

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] See also Figures 1 to 5 The embodiment of the utility model discloses a door-type mesh water curtain dust suppression device for coal mines, which is mainly composed of a detachable frame 1 and a support frame 2. A water pipe 101 is installed on the upper part of the frame 1, and a nozzle is installed on the water pipe 101. The nozzle is used to spray water mist, and the spray direction of the nozzle is toward the mesh rope. The sprayed water forms a water curtain on the crossed mesh ropes to intercept and reduce dust. A plurality of connecting rings 102 are arranged on the inner side of the frame 1. The connecting ring 102 is rotatably arranged on the inner side of the frame 1 through a sleeve, providing a connection point for the connection of the mesh rope, so that one point of the mesh rope can be flexibly hung. A support frame 2 is provided at the bottom of the frame 1. The support frame 2 can be made of I-beam or a larger structure to ensure the stability of the device.

[0021] The upper frame 1 is connected to the side wall of the mine through expansion bolts. The upper frames 1 can be arranged accordingly according to the installation space, and do not need to be connected together at the top, as long as they are on the same vertical plane. The mesh ropes between different frames 1 can be woven accordingly as needed. It has wide applicability and is easy to install. It does not need to significantly change the structure of the frame 1, thereby reducing labor intensity.

[0022] At the connection between the frame 1 and the support frame 2, a mounting rod 3 is horizontally arranged, and the net ropes installed on the connecting rings 102 on the frame 1 in the upper, left and right directions can be tightened by the locking blocks 305 on the mounting rod 3. The net ropes at the corners of the frame 1 are connected between the connecting rings 102 in pairs to ensure the surface of the net rope connection. The frame 1 is connected at both ends of the mounting rod 3 through spherical heads and flanges to ensure the stability of the connection, adapt to different connection spaces, facilitate adjustment, and improve controllability.

[0023] An installation groove 303 is formed on the upper portion of the installation rod 3 along the length direction, and the cross section of the installation groove 303 is designed to be T-shaped. The cam 306 is a substantially rectangular shape with a plurality of holes formed on the top of the mounting hole 303, and the cam 306 is a substantially rectangular shape with a plurality of holes formed on the top of the mounting hole 303. The cam 306 is a substantially rectangular shape with a plurality of holes formed on the top of the mounting hole 303, and the cam 306 is a substantially rectangular shape with a plurality of holes formed on the top of the mounting hole 303. First, move the locking block 305 to the corresponding position inside the mounting groove 303, then pass the net rope through the hole in the center of the locking bolt 306 and the mounting hole on the locking block 305, and then pass it through the through hole at the bottom of the mounting groove 303. When locking, tighten the net rope under the mounting rod 3, and then tighten the locking bolt 306 to keep the net rope taut. After tensioning, cut off the net rope below, and seal the through hole with a plug after cutting it off. By rotating the locking bolt 306, the net rope can be locked and fixed to ensure that the net rope can fit tightly on the frame 1 to form a tight dust catching net. The sliding of the locking block 305 can adapt to the net rope in all directions. The mounting holes on the locking block 305 are provided with at least two rows, and a tight dust catching net is formed by cross-weaving. The mounting structure can be adjusted according to the use environment and is suitable for a variety of complex installation environments to ensure dustproof effect and improve convenience during installation.

[0024] In order to facilitate the installation of the equipment pipe 202 and the door 201, a through hole is reserved through the support frame 2 below the installation rod 3. At the same time, a receiving frame is set in the middle position of the support frame 2 for the conveyor belt 203 to pass through, ensuring that the conveyor belt 203 will not interfere with the device when passing through. In order to improve the dust reduction effect, a water receiving box 4 is set in the middle position of the installation rod 3. The water receiving box 4 is used to receive the water flowing down from the installation rod 3. The water receiving box 4 is located above the conveyor belt 203, and a water outlet facing the conveyor belt 203 is opened at the bottom. When the conveyor belt 203 passes, the water in the water receiving box 4 can be sprayed onto the conveyor belt 203 through the water outlet, further reducing the dust on the conveyor belt 203. At the same time, a drainage pipe 101 is also provided on the side of the water receiving box 4 to facilitate the discharge of excess water.

[0025] A drainage groove 304 is set in the installation groove 303, and water is sprayed on the net rope through the head, and the water flows downward into the drainage groove 304. A notch 301 is opened on the side of the installation rod 3 for installing a locking block 305. When installing the locking block 305, a single locking block 305 is stuck close to the inside of the installation groove 303 from the notch 301. After the installation is completed, a blocking block 302 is bolted inside the notch 301 to position the locking block 305 to prevent the locking block 305 from sliding out of the notch 301. The notch 301 is set above the water tank, which is not only convenient for workers to operate, but also the water flowing out of the notch 301 will enter the water receiving box 4, thereby improving the collection effect and effectively improving the utilization rate of water resources. It has the function of efficient dust reduction, is easy to install, and is flexible to adjust. It can adapt to mines of different shapes and sizes, improves the dust reduction effect, and ensures the health and safety of miners.
