[0002] The spray-coated power-specific cooling device is an active cooling technology used for power equipment (such as transformers, switchgear, cable joints, etc.). It rapidly reduces the surface temperature of the equipment by spraying special materials or liquid media to ensure the safe and stable operation of the power system.

[0003] In existing technologies, a continuous structure is sprayed from the spray nozzle. Sometimes the cooling agent is conductive. When the spraying device acts on some electrical components, the continuous structure sprayed out can form a wire, causing the current in the electrical equipment to flow to the spraying device, which can damage the spraying equipment and introduce safety hazards.

[0004] Based on this, this utility model designs a cooling device for spraying a special cooling agent for power plants to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling device for spraying a cooling agent specifically for power applications, in order to solve the problem mentioned in the background art where the spraying cylinder sprays a continuous structure. Sometimes the cooling agent is conductive, and when the spraying device acts on some electrical components, the continuous spraying structure will form a wire, causing the current on the electrical equipment to flow to the spraying device, which will damage the spraying device and bring about safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for spraying a cooling agent specifically for power plants, comprising a device body, the device body including a base, a pressure device mounted on the base, a cooling agent tank and a controller mounted on the base, the pressure device being connected to the cooling agent tank and providing pressure to the cooling agent tank, the controller being connected to the pressure device, a spraying device being disposed above the cooling agent tank, a support column being fixedly mounted on the upper wall of the cooling agent tank, the spraying device being fixedly mounted on the support column, the spraying device being connected to the cooling agent tank through a delivery pipe, the spraying device including a distribution box, the distribution box being fixedly mounted on the support column, multiple spraying pipes being connected to the upper end of the distribution box, a nozzle being fixedly mounted at the top of each spraying pipe, a valve being fixedly mounted inside the spraying pipe, a sealing ring being disposed inside the distribution box, and a through hole being opened on the sealing ring.

[0007] Preferably, the valve includes a fixed sleeve, a fixed rod is fixedly installed on the inner wall of the fixed sleeve, a limit plate is fixedly installed below the fixed rod, a spring is fixedly installed on the lower wall of the limit plate, a sealing post is provided around the spring, the bottom end of the inner wall of the sealing post is connected to the other end of the spring, an outlet is provided at the lower end of the fixed sleeve, the outlet is located on the side of the sealing post, a sealing ring is provided below the outlet, the sealing ring is fixedly installed on the inner wall of the fixed sleeve, and the sealing post is slidable.

[0008] Preferably, the sealing ring is rotatable within the diverter box, a drive motor is provided on the side of the sealing ring, the output end of the drive motor is connected to the sealing ring, a motor box is provided around the drive motor, the drive motor is fixedly installed in the motor box, and the motor box encloses the diverter box and is fixedly installed on the support column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves segmented spraying during use through the spraying device, making the spraying of equipment safer. Through the design of the sealing ring, drive motor, and valve, the drive motor drives the sealing ring to rotate, and the cooling agent in the cooling agent tank enters the distribution box under pressure. Then, it enters the spraying pipe through the through hole on the sealing ring. Since multiple spraying pipes are provided, when the sealing ring rotates and the through hole passes under the spraying pipe, the cooling agent enters the spraying pipe and is sprayed out. After leaving, it cannot enter the spraying pipe for spraying, thus forming a multi-segment spraying effect. This avoids the cooling agent from becoming a conductor and causing damage to the equipment when a short circuit occurs. In addition, the design of the valve ensures that the spraying pipe is sealed when no cooling agent is passing through. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1-4 This utility model provides a technical solution: a device for spraying a cooling agent specifically for power plants, comprising a device body, a base 1, a pressure device 3 mounted on the base 1, a cooling agent tank 5 and a controller 2 mounted on the base 1, the pressure device 3 being connected to the cooling agent tank 5 and providing pressure to the cooling agent tank 5, the controller 2 being connected to the pressure device 3, a spraying device 8 being disposed above the cooling agent tank 5, a support column 6 being fixedly mounted on the upper wall of the cooling agent tank 5, and the spraying device 8 being fixedly mounted on the support column 6, the spraying device 8 being connected to the cooling agent tank through a delivery pipe 7. 5. The spraying device 8 includes a diversion box 23, which is fixedly installed on the support column 6. Multiple spraying pipes 9 are connected to the upper end of the diversion box 23. A nozzle 10 is fixedly installed at the top of the spraying pipe 9. A valve is fixedly installed inside the spraying pipe 9. A sealing ring 22 is provided inside the diversion box 23. A through hole 17 is opened on the sealing ring 22. Through the diversion box 23 and multiple spraying pipes 9, in conjunction with the sealing ring 22, this device enables each spraying pipe 9 to spray in turn, forming a multi-segment spraying effect. This prevents current from being conducted from the electrical equipment to the device, making the device safer to use.

[0022] Please see the appendix Figure 3 The valve includes a fixed sleeve 15, a fixed rod 14 fixedly installed on the inner wall of the fixed sleeve 15, a limit plate 16 fixedly installed below the fixed rod 14, a spring 20 fixedly installed on the lower wall of the limit plate 16, a sealing post 18 arranged around the spring 20, the bottom end of the inner wall of the sealing post 18 connected to the other end of the spring 20, an outlet 19 arranged at the lower end of the fixed sleeve 15, the outlet 19 is located on the side of the sealing post 18, a sealing ring 21 is arranged below the outlet 19, the sealing ring 21 is fixedly installed on the inner wall of the fixed sleeve 15, and the sealing post 18 is slidable. Through the valve mechanism, when cooling agent passes through the spray pipe 9, the valve opens under the pressure of the cooling agent, forming a flow. When no cooling agent passes through, the valve keeps the spray pipe 9 sealed under the action of the spring 20.

[0023] Please see the appendix Figure 3 and attached Figure 4 The sealing ring 22 can rotate within the distribution box 23. A drive motor 24 is provided on the side of the sealing ring 22. The output end of the drive motor 24 is connected to the sealing ring 22. A motor box 13 is provided around the drive motor 24. The drive motor 24 is fixedly installed in the motor box 13. The motor box 13 encloses the distribution box 23 and is fixedly installed on the support column 6. Through the design of the sealing ring 22, the cooling agent is sprayed evenly onto the electrical equipment at intervals under the drive of the drive motor 24. Each spraying pipe 9 sprays in turn, forming segments. It is convenient to use, has a simple structure, and is not easily damaged.

[0024] Please see the appendix Figure 2 A fixing plate 11 is provided on the side of the spraying device 8. The fixing plate 11 fixes the spraying pipes 9 so that each spraying pipe 9 can spray in the designated place. One end of the fixing plate 11 is connected to the spraying pipe 9, and the other end of the fixing plate 11 is connected to the motor box 13. A locking button 12 is provided at the end of the fixing plate 11 connected to the motor box 13. The number of fixing plates 11 is kept consistent with the number of spraying pipes 9. A feed port 4 is provided at the top of the cooling agent tank 5.

[0025] A specific application of this embodiment is as follows: When this utility model is in use, the controller 2 controls the pressure device 3 to start, and the pressure device 3 pushes the cooling agent in the cooling agent tank 5 into the spraying device 8. The cooling agent enters the distribution box 23 through the delivery pipe 7. At the same time, the drive motor 24 starts, driving the sealing ring 22 to rotate. Since the sealing ring 22 has a through hole 17, when the through hole 17 moves below the spraying pipe 9, the cooling agent enters the spraying pipe 9 through the through hole 17. After entering the spraying pipe 9, the cooling agent pushes the sealing column 18 to move upward. Simultaneously, the spring 20 contracts under force, and the cooling agent passes through the outlet 19. After passing through, the cooling agent is sprayed onto the electrical equipment via the nozzle 10. Since the sealing ring 22 is rotating, the time for the cooling agent to pass through each spray tube 9 is limited. When the through hole 17 leaves below the spray tube 9, the corresponding nozzle 10 cancels the spraying. Then, when the through hole 17 passes through the next spray tube 9, the corresponding nozzle 10 sprays. The spraying is carried out in a cycle, so that the cooling agent is sprayed in segments, ensuring safety during use. Moreover, this equipment is simple to use and easy to operate.
