Description

Technical Field

[0001] This utility model relates to the field of mining, and in particular to a well cooling device. Background Technology

[0002] As underground mining progresses to deeper levels, it brings with it the problems of "high temperatures, high humidity, high temperature, high temperature, and high temperature disturbance." According to measurement data, the deeper the underground, the higher the geothermal temperature. The geothermal gradient is generally 30-50℃ / km, with a normal gradient of 30℃ / km. However, near some faults or in abnormally hot local areas with high thermal conductivity, the geothermal gradient can reach as high as 200℃ / km. Studies have shown that a 1℃ temperature change within a rock mass can generate a 0.4-0.5MPa change in geostress. Therefore, high geothermal environments have a significant impact on the mechanical properties of deep rocks, such as making them prone to large-scale rheological changes and plastic instability. According to the actual temperature measurements in the Dahongshan Copper Mine, the temperature in the 185 section is 26-28℃, the temperature in the -20 section is 30-35℃, and the temperature in the single-ended tunnel reaches as high as 40℃.

[0003] The high temperature underground often leads to heatstroke among on-site workers. On-site ventilation and cooling can usually only be achieved through fans, but the heat dissipation effect of fans is limited due to the high temperature underground.

[0004] Therefore, it is necessary to provide a well cooling device to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a well cooling device provided by this utility model; Figure 2 for Figure 1 A cross-sectional structural schematic diagram of the support frame shown; Figure 3 for Figure 2 The enlarged schematic diagram of section A is shown. A well cooling device includes:

[0027] Storage container 1, with an air inlet pipe 2 fixedly installed at one end of the storage container 1 and a fan 3 fixedly installed at the other end of the storage container 1;

[0028] A sealing plate 4 is disposed inside the storage bucket 1, and a handle 5 is fixedly connected to the outer surface of the sealing plate 4;

[0029] Two mounting rings 6 are provided on the surface of the storage bucket 1, and a support frame 7 is fixedly connected to the surface of the mounting rings 6.

[0030] The storage container 1 has an inlet, and the sealing plate 4 is adapted to the inlet. One end of the sealing plate 4 is connected to the storage container 1 by a hinge, so that the sealing plate 4 can rotate to one side. At the same time, the other end of the sealing plate 4 can be limited by a magnet or a snap fastener.

[0031] The handle 5 is used to facilitate picking up one end of the sealing plate 4 and rotating it to one side.

[0032] Storage tank 1 is used to store ice blocks, so that outside air enters the interior of storage tank 1 through air inlet pipe 2, comes into contact with the ice blocks and cools down, and is then blown out by fan 3, thereby increasing the cooling of the internal space in the well.

[0033] Two mounting rings 6 are fixedly connected to both ends of the bottom surface of the storage barrel 1, and are used to support the storage barrel 1 in conjunction with the support frame 7.

[0034] One side of each of the four ends of the support frame 7 is fixedly connected to one end of each of the two mounting rings 6.

[0035] The support frame 7 has four lifting holes 8 inside, and each of the four lifting holes 8 is threaded with a lifting rod 9.

[0036] The lifting rod 9 is a threaded rod, and the lifting hole 8 is a threaded hole adapted to the lifting rod 9, used to move to one side inside the lifting hole 8 when the lifting rod 9 rotates to one side.

[0037] Each of the four lifting rods 9 has a support rod 10 fixedly connected to one end, and each of the four support rods 10 has a support base 11 fixedly connected to one end.

[0038] By rotating the support rod 10 to one side, the lifting rod 9 rotates to one side inside the lifting hole 8. At the same time, the lifting rod 9 moves to one side inside the lifting hole 8, thereby moving the support rod 10 connected to the support seat 11. This allows the position of multiple support seats 11 to be adjusted so that the four corners of the support frame 7 are on the same horizontal plane, increasing the stability during support.

[0039] The working principle of the well cooling device provided by this utility model is as follows:

[0040] In use, by moving the handle 5 to one side, the sealing plate 4 is rotated to one side and opened, and then ice cubes are placed inside the storage container 1.

[0041] After the blower 3 is started, the outside air enters the storage tank 1 through the air inlet pipe 2, comes into contact with the ice to cool down, and is then blown out by the blower 3, thereby increasing the cooling of the internal space in the well.

[0042] Compared with related technologies, the well cooling device provided by this utility model has the following beneficial effects:

[0043] This utility model provides a well cooling device. After heating ice blocks inside the storage tank 1, the fan 3 is activated to allow outside air to enter the storage tank 1 through the air inlet pipe 2. After the air comes into contact with the ice blocks and is cooled, it is blown out by the fan 3, thereby increasing the cooling of the internal space of the well and preventing the workers in the well from experiencing physical discomfort due to working in a high-temperature environment for a long time.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 4 and Figure 5 Based on the well cooling device provided in the first embodiment of this application, the second embodiment of this application proposes another well cooling device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference in the well cooling device provided in the second embodiment of this application is that the well cooling device has two sliding grooves 12 inside the air inlet pipe 2, and sliding blocks 13 are slidably connected inside the two sliding grooves 12.

[0047] One side of each of the two sliding blocks 13 is fixedly connected to both sides of the filter box 14 for positioning during installation, and one end of each of the two sliding grooves 12 is open.

[0048] A filter box 14 is fixedly connected to one side of the sliding block 13. The filter box 14 is provided with two first filter elements 15 and a second filter element 16.

[0049] The first filter element 15 is a filter screen used to filter dust in the air entering the filter box 14.

[0050] The second filter element 16 is an activated carbon layer, used to adsorb dust, odors, and other pollutants in the air.

[0051] One end of the air intake pipe 2 is fixedly connected to a fixing sleeve 17, and a fixing ring 18 is threadedly connected inside the fixing sleeve 17.

[0052] The fixing sleeve 17 is a threaded sleeve, and the surface of the fixing ring 18 is provided with a thread that is compatible with the fixing sleeve 17. It is used to move to one side inside the fixing sleeve 17 when the fixing ring 18 rotates to one side. When one side of the fixing ring 18 contacts one end of the filter box 14, it limits the filter box 14.

[0053] The fixed ring 18 has two concave handles inside, which facilitates the rotation of the fixed ring 18.

[0054] The working principle of the well cooling device provided by this utility model is as follows:

[0055] In use, when external air enters through the air intake pipe 2, the air drawn in through the first filter element 15 and the second filter element 16 is filtered, thereby filtering the air inside the well.

[0056] When it needs to be replaced, the filter box 14 is pulled to one side by rotating the fixing ring 18 to one side, thereby moving and separating it inside the fixing sleeve 17. Then, the filter box 14 is pulled to one side, which causes the two sliding blocks 13 to move and separate to one side inside the two sliding grooves 12 respectively. The filter box 14 can then be removed and replaced.

[0057] After inserting the two sliding blocks 13 on both sides of the new filter box 14 into the two sliding grooves 12 respectively, and moving them to a suitable position to one side, the fixing ring 18 is installed into the fixing sleeve 17.

[0058] Compared with related technologies, the well cooling device provided by this utility model has the following beneficial effects:

[0059] This utility model provides a well cooling device that filters the air drawn in by the air intake pipe 2 through the first filter element 15 and the second filter element 16, thereby filtering the air inside the well. At the same time, the sliding groove 12, in conjunction with the sliding block 13, the fixing sleeve 17 and the fixing ring 18, facilitates the replacement of the first filter element 15 and the second filter element 16.

[0060] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
