Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0020] Example 1: like Figure 1-4 As shown, the coal mine electromechanical cooling device provided by this utility model includes: a trolley 1, a column 2 mounted on the trolley 1, a spraying mechanism mounted on the column 2, the spraying mechanism including a guide rod 3 fixedly mounted on one side of the column 2, a support plate 4 slidably mounted on the guide rod 3, a spray pipe 5 mounted on the bottom of the support plate 4, multiple spray holes or multiple nozzles installed on the downward-facing side of the spray pipe 5, the spray pipe 5 being connected to a high-pressure water source to achieve spraying cooling of the coal mine electromechanical equipment below, and a drive assembly 6 mounted on the top of the column 2, the drive assembly 6 being used to drive the support plate 4 to move along the guide rod 3, the drive assembly 6 including a fixed... A first column 9 is installed on the top of the column 2. A first mounting cavity 10 is opened in the first column 9. A first piston column 11 is slidably installed in the first mounting cavity 10. A first push rod 12 is fixedly installed on one side of the first piston column 11. One end of the first push rod 12 extends out of the first column 9 and is fixedly connected to the support plate 4. A first water inlet pipe 13, a second water inlet pipe 14 and a water outlet pipe 15 are installed on the first column 9 and communicate with the first mounting cavity 10. The stroke of the first piston column 11 is located between the first water inlet pipe 13 and the second water inlet pipe 14. The first water inlet pipe 13 and the second water inlet pipe 14 are connected to a high-pressure water source. In use, the device is moved to the side of the coal mine machinery and equipment that needs cooling. The water outlet pipe 15 is closed, and high-pressure water is injected into the first mounting cavity 10 on the right side of the first piston column 11 through the second water inlet pipe 14. This increases the pressure on the right side of the first piston column 11, causing it to move to the left. This, in turn, causes the first push rod 12 to push the support plate 4 away from the column 2, thus moving the spray pipe 5 above the part of the coal mine machinery and equipment that needs cooling. Then, high-pressure water is injected into the spray pipe 5, which sprays out high-pressure water mist to cool the coal mine machinery and equipment below. After the device is used, the water outlet pipe 15 is opened, and water is injected into the space of the first mounting cavity 10 on the left side of the first piston column 11 through the first water inlet pipe 13 to increase the pressure. This causes the first piston column 11 to move to the right, and the water in the space on the right side of the first piston column 11 is discharged through the water outlet pipe 15. At the same time, the spray pipe 5 moves to the right, gradually approaching the column 2. It is worth noting that the water source can be an existing high-pressure water source underground or other water sources. Since no motors or other electrical components are used, the risk of electric leakage is reduced, making the device safer to use.

[0021] By setting up a trolley 1, a column 2, and a spraying mechanism, it is possible to conveniently spray and cool down the electromechanical equipment in the coal mine. The drive assembly, which includes a fixed first column 9, a first mounting cavity 10, a first piston column 11, a first push rod 12, a first water inlet pipe 13, a second water inlet pipe 14, and a water outlet pipe 15, can use water power to drive the spraying mechanism to move and change the spraying position, effectively improving the safety of the device.

[0022] Example 2: like Figure 1 and Figure 3 As shown, in this embodiment, the column 2 includes a second column 25 fixedly mounted on the trolley 1. A second mounting cavity 26 is opened in the second column 25. A second piston column 27 is slidably mounted in the second mounting cavity 26. A second push rod 28 is fixedly mounted at one end of the second piston column 27. The second push rod 28 is fixedly connected to the guide rod 3 and the first column 9. An inlet and outlet are provided on the second column 9 near one end of the second mounting cavity 26. High-pressure water can be injected into the second mounting cavity 26, causing the second piston column 17 to move and push the second push rod 28 away from the second column 25, thereby adjusting the height of the spray pipe 5. Similarly, water in the second mounting cavity 26 can also be discharged through the inlet and outlet. Under the action of gravity, the second push rod 28 descends.

[0023] By setting up a column 2 including a second column 25, a second mounting cavity 26, a second piston column 27, and a second push rod 28, the height of the spray pipe 5 can be easily adjusted by injecting high-pressure water into the second mounting cavity 26, making it suitable for use in coal mine electromechanical systems of different heights.

[0024] Example 3: like Figure 1 and Figure 4 As shown, in this embodiment, a water tank 8 is installed on the trolley 1, a water pump 29 is installed on the water tank 8, and a first hose 7 of sufficient length is installed between the water pump 29 and the spray pipe 5. When in use, the water pump 29 draws water from the water tank 8 and supplies water to the spray pipe 5 through the first hose 7.

[0025] By setting up the first hose 7, the water storage tank 8 and the water pump 29, water can be conveniently supplied to the spray pipe 5.

[0026] Example 4: like Figure 2 and Figure 4As shown, a first three-way valve 16 is installed at the outlet of the water pump 29. The first three-way valve 16 is connected to one end of the first hose 7. A second three-way valve 17 is installed at one end of the first three-way valve 16. A third three-way valve 18 and a fifth three-way valve 20 are installed on the second three-way valve 17. A second connecting pipe 22 is installed between the third three-way valve 18 and the second inlet pipe 14. A fourth three-way valve 19 is installed at one end of the third three-way valve 18. A first connecting pipe 21 is installed between the fourth three-way valve 19 and the first inlet pipe 13. Both the first connecting pipe 21 and the second connecting pipe 22 are rubber hoses. One end of the fifth three-way valve 20 is connected to the second mounting cavity 26. One end of both the fourth three-way valve 19 and the fifth three-way valve 20 is connected to the water storage tank 8. A third connecting pipe 23 is installed between the water storage tank 8 and the outlet pipe 15. The third connecting pipe 23 is also a rubber hose. A valve 24 is installed on the third connecting pipe 23. Water discharged from the outlet pipe 15 flows back into the water storage tank 8, which can save water. In use, the water from the pump 29 can flow into the spray pipe 5 through the first hose 7 via the first three-way valve 16. Alternatively, the water from the pump 3 can flow through the first three-way valve 16 to the second three-way valve 17, and then the second three-way valve 17 can select the direction of the water to the third three-way valve 18 or the fifth three-way valve 20. The third three-way valve 19 can select the direction of the water to the fourth three-way valve 19 or the second inlet pipe 14. The fourth three-way valve 19 can select the direction of the water to the first inlet pipe 13 or the water to return to the water storage tank 8. The fifth three-way valve 20 can select the direction of the water to the second mounting cavity 26 or the water in the second mounting cavity 26 can return to the water storage tank 8.

[0027] By setting the first three-way valve 16, the second three-way valve 17, the third three-way valve 18, the fourth three-way valve 19, and the fifth three-way valve 20, and installing the corresponding connecting pipes, the water flow direction of the water pump 3 can be easily controlled, facilitating the supply of water to the column 2, the drive assembly 6, and the spray pipe 5.

[0028] Working principle: When in use, move the device to the side of the coal mine electromechanical equipment that needs to be cooled, close the water outlet pipe 15, and inject high-pressure water into the first mounting cavity 10 on the right side of the first piston column 11 through the second water inlet pipe 14. This increases the pressure on the right side of the first piston column 11, causing the first piston column 11 to move to the left. This, in turn, causes the first push rod 12 to push the support plate 4 to move away from the column 2. As a result, the spray pipe 5 moves to the area above the coal mine electromechanical equipment that needs to be cooled. Then, high-pressure water is injected into the spray pipe 5, and the spray pipe 5 sprays out high-pressure water mist to perform spray cooling operation on the coal mine electromechanical equipment below.

[0029] After the device is used, open the water outlet pipe 15 and inject water into the space of the first mounting cavity 10 on the left side of the first piston column 11 through the first water inlet pipe 13 to increase the pressure, so that the first piston column 11 moves to the right. The water in the space on the right side of the first piston column 11 is discharged through the water outlet pipe 15. At the same time, the spray pipe 5 moves to the right and gradually approaches the column 2.
