At the blasting site, in order to ensure the safety of personnel and the surrounding environment, isolation equipment is needed to limit the blasting area and prevent debris, shock waves, etc. from causing damage to the surrounding area.

[0003] According to announcement number CN217005553U, an isolation device for explosive blasting sites includes a base, the top of the base is fixedly connected to a rotating shaft, the top of the base is movably connected to a support frame via the rotating shaft, the inner wall of the support frame is fixedly connected to a protective partition net, and the outer wall of the support frame is fixedly connected to a movable shaft.

[0004] The above solution facilitates the modification of the device's protection range according to on-site conditions, making the device easier to transport, extending its usable range, and increasing the device's usable area. However, the terrain and environmental conditions at blasting sites are often complex, and the above solution only supports the equipment with foot supports, which is not effective.

Under the impact of the blasting, it may shift or collapse during the blasting process, thereby reducing the isolation effect and increasing safety hazards. Therefore, the isolation function cannot be effectively exerted, which has certain shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides an isolation device for explosive blasting sites. The utility model can fix the base 5 by means of the fixing mechanism 7, thereby achieving the effect of fixing the position of the entire isolation device. The support mechanism 9 can stably support the frame 1. The fixing mechanism 7 and the support mechanism 9 cooperate with each other, thereby enabling the isolation net 2 to be firmly fixed and supported, thereby avoiding the isolation device from being easily displaced or collapsed due to the impact force of the blasting during the blasting process, improving the isolation effect, reducing safety hazards, and thus being able to effectively play the isolation role.

[0023] See also Figures 1 to 4 The frame 1 is made of high-strength steel, has high strength and stability, and can withstand various impacts and pressures at the blasting site. Its shape is a regular frame structure with smooth edges and corners and no sharp parts, which can effectively reduce safety risks.

[0024] The isolation net 2 is firmly installed on the inner wall of the frame 1 by reliable means, such as welding or tightening bolts. The isolation net 2 is woven from high-strength metal wire, such as high-quality stainless steel wire, and has excellent tensile strength and corrosion resistance. It can maintain a good condition for a long time in harsh environments. Its mesh structure is tight and the mesh size is appropriate. It can effectively block gravel, shock waves, etc. without affecting the line of sight, which is convenient for on-site personnel to observe. At the explosive blasting site, the isolation net 2 plays an important isolation and protection role, which can effectively prevent gravel, shock waves, etc. from causing harm to surrounding personnel and the environment.

[0025] The rotating shaft 3 is made of a solid metal material to ensure stable and reliable rotation, and is rotatably connected to the base 5 through a precision bearing.

[0026] Knob 1 4 is usually made of durable plastic or metal, and has a non-slip texture on the surface for easy operation. By rotating knob 1 4 , the shaft 3 , the frame 1 and the isolation net 2 can be driven to rotate, thereby achieving the angle adjustment effect of the isolation net 2 .

[0027] The base 5 is made of heavy metal material to increase the stability of the equipment and provide solid support for the entire isolation device.

[0028] The insertion rod 601 of the limiting mechanism 6 is made of metal and has sufficient strength and hardness. It is shaped like a slender rod, and the sliding connection part with the inner wall of the base 5 is smooth, ensuring that the insertion rod 601 can slide smoothly. The insertion rod 601 is installed in the slideway of the inner wall of the base 5 and can slide freely. The pull tab 602 is made of plastic or metal and has certain strength and durability. It has a sheet structure, which is convenient for pulling the insertion rod 601. The elastic part 603 is a spring with good elastic properties. It is sleeved on the outer surface of the insertion rod 601, one end is fixedly connected to the pull tab 602, and the other end is fixedly connected to the base 5.

[0029] The adjusting screw 701 of the fixing mechanism 7 is made of high-strength metal with high thread precision. One end of the adjusting screw 701 is fixedly connected to the second knob 702 , and the other end is connected to the rotating piece 703 .

[0030] The second knob 702 is convenient for the operator to rotate, and the rotating piece 703 is rotatably connected to the support plate 704. The support plate 704 is made of metal and has certain strength and load-bearing capacity. The bottom surface is fixedly connected to the fixing nail 705. The fixing nail 705 is made of hard material and has a sharp tip, which can be easily inserted into the ground.

[0031] The limiting block 8 is made of metal and has certain strength and wear resistance. It is fixed on the outer surface of the frame 1 to provide rotation support and limit for the rotating rod 901.

[0032] The rotating rod 901 of the supporting mechanism 9 is made of metal and has certain strength and rigidity.

[0033] The storage tube 902 is made of metal, has a suitable internal space, and the inner wall thread matches the fixing screw 904.

[0034] The adjusting rod 903 can be extended and retracted in the storage tube 902, and the fixing screw 904 can be inserted into the adjusting rod 903 for fixing.

[0035] The support block 905 is firmly connected to the adjustment rod 903 and can provide stable support for the frame 1. The outer surface of the support block 905 is provided with multiple protruding metal sheets, and the metal sheet can be easily inserted into the ground, thereby increasing the anti-slip ability and supporting ability of the support block 905.

[0036] Working principle: When in use, the isolation device is moved to the specified position by the moving wheel 10, and then, by rotating the knob 2 702, the adjusting screw 701 is driven to rotate, so that the rotating piece 703, the support plate 704 and the fixing nail 705 move downward, and the fixing nail 705 is inserted into the ground, thereby fixing the base 5. Then, the angle of the isolation net 2 is adjusted as needed, and the pull tab 602 is pulled to drive the insertion rod 601 to be pulled out from the inside of the knob 1 4. At the same time, the pull tab 602 stretches the elastic part 603 to cause it to deform and store elastic potential energy, and then the knob 1 4 is turned to drive the rotating shaft 3, the frame 1 and the isolation net 2 to rotate accordingly, so that the placement angle of the frame 1 and the isolation net 2 can be adjusted. After adjusting the angle of the isolation net 2, release the pull tab 602, and the elastic part 603 drives the pull tab 602 and the insertion rod 601 in the opposite directions. Move the rod 601 to reinsert it into the knob 4, fix the knob 4, the shaft 3, the frame 1 and the isolation net 2, and then rotate the rotating rod 901 to adjust the storage tube 902, the adjusting rod 903 and the support block 905 to the appropriate position, so that the adjusting rod 903 extends or retracts in the storage tube 902, and fixes both the storage tube 902 and the adjusting rod 903 by the fixing screw 904, thereby adjusting the height of the support block 905 so that it contacts the ground and stably supports the frame 1. Through the mutual cooperation of the fixing mechanism 7 and the supporting mechanism 9, the isolation net 2 can be firmly fixed and supported, avoiding the isolation equipment from being easily displaced or collapsed due to the impact force of the blasting during the blasting process, thereby improving the isolation effect, reducing safety hazards, and effectively playing the isolation role.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
