Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage electrical fire protection and relates to a high-voltage electrical fire protection water spraying device. Background Art

[0002] In the area of high-voltage electrical equipment, the prevention and control of fires have always been important issues in the safety field. Since high-voltage electrical equipment may generate dangerous factors such as high temperature and electric arc during operation, once a fire occurs, it will not only cause serious damage to the equipment, but may also trigger a chain reaction, resulting in disasters on a larger scale. Therefore, the fire safety of high-voltage electrical equipment is particularly important.

[0003] Traditional fire protection water spraying devices have certain limitations when dealing with fires of high-voltage electrical equipment. First of all, most of these devices rely on the hydraulic pressure provided by the initial fire pump to carry out water spraying for fire extinguishing. However, during the working process, due to the influence of various factors such as water flow resistance and pipeline friction, the spraying pressure often shows unstable conditions. This instability of pressure will not only affect the fire extinguishing effect of the water spraying device, but may also cause the deviation of the locked position of the water spraying, making the fire extinguishing point unable to accurately aim at the fire source, thus reducing the fire extinguishing efficiency.

[0004] In addition, when adjusting the water spraying angle and range of traditional fire protection water spraying devices, manual intervention and adjustment are often required. In the emergency situation of a fire in high-voltage electrical equipment, this manual adjustment method obviously cannot meet the requirements of rapid response and accurate fire extinguishing. Once the fire spreads too fast, manual adjustment may not be able to keep up in time, resulting in the further expansion of the fire.

[0005] More critically, high-voltage electrical equipment may be prone to leakage during a fire. If the fire protection water spraying device comes into contact with the leaking equipment or water flow during the fire extinguishing process, it may trigger an electric shock accident, causing serious harm to rescue personnel. Traditional fire protection water spraying devices often lack a warning and protection mechanism for leakage situations and cannot issue an alarm and take corresponding measures in time when leakage is detected.

[0006] With the continuous progress of technology and the continuous improvement of fire safety requirements, people have begun to seek more advanced and efficient fire protection water spraying devices to deal with the fire problems of high-voltage electrical equipment. These new devices need to have stable water spraying pressure, accurate water spraying angle adjustment ability, and a warning and protection mechanism for leakage situations to ensure that they can quickly and effectively extinguish and control the fire when a fire occurs, while minimizing the damage to high-voltage electrical equipment and the harm to rescue personnel.

[0007] Therefore, there is an urgent need for a high-voltage electrical fire protection water spraying device. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a high-voltage electrical fire-fighting water spraying device. Through innovative designs and technical means, it aims to solve the many problems existing in traditional fire-fighting water spraying devices when dealing with high-voltage electrical equipment fires, and provide a more reliable and efficient guarantee for the fire safety of high-voltage electrical equipment.

[0014] Optionally, the front and rear ends of the double-headed motor are connected to the first gear. The lower end of the first gear meshes with the second gear. The middle part of the second gear penetrates and installs the rotating shaft. The front and rear ends of the rotating shaft are connected to the connecting head; the double-headed motor drives the rotating shaft through the first gear and the second gear to adjust the longitudinal angle of the water spray pipe.

[0015] Optionally, the driving motor is installed inside the mounting box, and the rotating end of the driving motor is connected to the mounting frame.

[0016] Optionally, an electromagnet is installed inside the isolation box. The positive pole of the power supply terminal of the electromagnet is connected to the immersion wire. The upper end of the electromagnet is connected to the first electrode, and the right end of the first electrode is connected to the power supply wire.

[0019] The beneficial effects of the present invention are as follows:

[0020] Steady pressure water spraying to improve fire extinguishing accuracy: During the operation of the high-voltage electrical fire-fighting water spraying equipment, water in the water inlet pipe is pumped above the plugging plate through the water return pipe, applying pressure to the plugging plate, and using the pressure relief valve to keep the pressure on the plugging plate constant. This design ensures that the pressure below the plugging plate also remains constant, thereby ensuring that the equipment can spray water with steady pressure, improving the accuracy of locking the fire extinguishing point, and enabling the equipment to have good fire extinguishing capabilities.

[0021] Leakage warning to ensure personnel safety: When it is found that there is leakage at the fire extinguishing point, the current in the equipment will conduct along the water flow to the immersion wire, making the electromagnet charged. After the electromagnet is charged, it will attract the first electrode and the second electrode to connect, thereby powering the alarm device and making the alarm device emit an alarm. This function enables the staff to quickly learn about the leakage situation, promptly cut off the power supply of the high-voltage electrical equipment, avoid greater losses caused by continued leakage, and at the same time ensure the safety of rescue personnel.

[0022] Precise adjustment to improve fire extinguishing efficiency: The equipment is equipped with a rotating assembly and an installation assembly. Through the coordinated operation of the double-headed motor and the driving motor, precise adjustment of the horizontal direction and longitudinal angle of the water spray pipe can be achieved. This design enables the equipment to quickly align with the fire source for precise fire extinguishing, improving the fire extinguishing efficiency and reducing the risk of fire spread.

[0023] Compact structure, easy to install and maintain: The equipment is designed with a compact structure, and the connection and layout between each component are reasonable, facilitating installation and disassembly. At the same time, the maintenance of the equipment is relatively simple, reducing the use cost and maintenance difficulty.

[0024] Intelligent control, adaptable to complex environments: This device can be used in conjunction with external intelligent devices such as fire sensors to achieve intelligent control. When a fire occurs, the fire sensor can quickly detect the location of the fire and control the device to extinguish the fire precisely. This intelligent control enables the device to adapt to complex and changing fire environments, improving the applicability and reliability of the device.

[0025] Energy-saving and environmental protection, reducing water waste: Through the design of stable pressure water spraying and precise adjustment, this device can make more effective use of water resources during the fire extinguishing process, reducing water waste. At the same time, the energy-saving design of the device also reduces energy consumption, meeting the environmental protection requirements of modern fire-fighting equipment.

[0026] In summary, through its unique design and technical means, this high-voltage electrical fire-fighting water spraying device has shown significant beneficial effects in aspects such as stable pressure water spraying, leakage warning, precise adjustment, compact structure, intelligent control, energy-saving and environmental protection, providing a more reliable and efficient guarantee for the fire safety of high-voltage electrical equipment.

[0036] Please refer to Figures 1 to 3 , which is a specific implementation manner of a high-voltage electrical fire-fighting water spraying device of the present invention. Specifically:

[0037] AsFigure 1 As shown in the figure, the water outlet assembly 1 includes a transfer tank 101, a water inlet pipe 102, a water spray pipe 103, a plugging plate 104, a water diversion pipe 105, a micro pump 106, a pressure relief valve 107 and a water return pipe 108. The left side of the transfer tank 101 is connected to the water inlet pipe 102, the right side of the transfer tank 101 is connected to the water spray pipe 103, and a plugging plate 104 is installed inside the transfer tank 101. The water inlet pipe 102 is connected to the water diversion pipe 105 above, and one end of the water diversion pipe 105 away from the water inlet pipe 102 is connected to the micro pump 106. The upper end of the water spray pipe 103 is connected to the water return pipe 108, and one side of the water return pipe 108 away from the water spray pipe 103 is connected to the pressure relief valve 107;

[0038] During the working process, the water return pipe 108 will pump the water in the water inlet pipe 102 into the upper part of the plugging plate 104, so that pressure will be exerted on the plugging plate 104. Through the pressure relief valve 107, the pressure on the plugging plate 104 is kept constant, so that the pressure below the plugging plate 104 can also be kept constant, thus ensuring that the equipment sprays water with stable pressure, ensuring the accuracy of the fire extinguishing point locking of the equipment, and facilitating the equipment to have good fire extinguishing ability.

[0039] As Figure 2 and Figure 3 shown in the figure, a rotating assembly 2 is installed in the middle of the upper end of the water outlet assembly 1, an installation assembly 3 is installed at the upper end of the rotating assembly 2, a magnetic attraction assembly 4 is installed on the right side of the installation assembly 3, and an alarm assembly 5 is installed inside the magnetic attraction assembly 4.

[0040] As Figure 2 shown in the figure, the rotating assembly 2 includes a double-headed motor 201, a first gear 202, a second gear 203, a rotating shaft 204 and a connector 205. The front and rear ends of the double-headed motor 201 are connected to the first gear 202, the lower end of the first gear 202 is connected to the second gear 203, and the rotating shaft 204 is installed through the middle of the second gear 203. The front and rear ends of the rotating shaft 204 are connected to the connector 205;

[0041] The double-headed motor 201 drives the first gear 202 to rotate, drives the rotating shaft 204 to rotate through the second gear 203, and makes the rotating shaft 204 drive the connector 205 to adjust the longitudinal angle of the water spray pipe 103.

[0042] As Figure 2 shown in the figure, the installation assembly 3 includes an installation box 301, a driving motor 302 and an installation frame 303. The driving motor 302 is installed inside the installation box 301, and the rotating end of the driving motor 302 is connected to the installation frame 303;

[0043] The driving motor 302 is used to control the installation frame 303 to rotate.

[0044] As Figure 3As shown in the figure, the magnetic attraction component 4 includes an isolation box 401, an electromagnet 402, a water-soaked wire 403, a first electrode 404, and a power supply wire 405. An electromagnet 402 is installed inside the isolation box 401. The positive electrode of the power supply end of the electromagnet 402 is connected to the water-soaked wire 403. The upper end of the electromagnet 402 is connected to the first electrode 404, and the right end of the first electrode 404 is connected to the power supply wire 405;

[0045] When it is found that there is a leakage at the fire extinguishing point, the current will conduct along the water flow to the water-soaked wire 403, thereby making the electromagnet 402 charged. In this way, the first electrode 404 and the second electrode 501 will be connected, thereby powering the alarm device 503 and making the alarm device 503 issue an alarm. In this way, the staff can quickly cut off the power supply of the high-voltage electrical equipment to avoid greater losses caused by continuous leakage.

[0046] As Figure 3 shown in the figure, the alarm component 5 includes a second electrode 501, a flexible wire 502, an alarm device 503, a spring 504, and a telescopic rod 505. The right side of the second electrode 501 is connected to the flexible wire 502, the right end of the flexible wire 502 is connected to the alarm device 503, a spring 504 is installed in the middle of the upper end of the second electrode 501, and telescopic rods 505 are connected to the left and right sides of the upper end of the second electrode 501;

[0047] Relying on the elastic structure formed between the second electrode 501 and the isolation box 401 through the spring 504 and the telescopic rod 505, it is convenient for the second electrode 501 to reset after the electromagnet 402 is powered off, so that the alarm device 503 stops working.

[0048] Embodiment 1,

[0049] After the external fire sensor detects a fire in the high-voltage electrical equipment, it will control the external fire pump to work, thereby delivering water to the transfer box 101, and then making the water spray out from the spray pipe 103 to carry out the fire extinguishing work. The fire sensor will also detect the location of the fire, and then control the mounting frame 303 to rotate through the drive motor 302, thereby adjusting the plane direction of the spray pipe 103. At the same time, the double-headed motor 201 will be turned on to drive the first gear 202 to rotate, thereby driving the rotating shaft 204 to rotate through the second gear 203, so that the rotating shaft 204 drives the connector 205 to adjust the longitudinal angle of the spray pipe 103, so that the spray pipe 103 can accurately extinguish the fire by aiming at the fire source;

[0050] Embodiment 2,

[0051] During the operation of the water spray fire extinguishing system, the micro pump 106 will draw the water inside the water inlet pipe 102 through the water diversion pipe 105, and transport the water above the sealing plate 104, so that there is a certain water pressure above the sealing plate 104, and the pressure is relieved through the pressure relief valve 107, so that the hydraulic pressure above the sealing plate 104 remains constant. The water flowing out of the pressure relief valve 107 will be transported back to the water spray pipe 103 through the water return pipe 108 for fire extinguishing work;

[0052] The function of the sealing plate 104 is that when the fire fighting water pressure becomes small, the sealing plate 104 will move downward under the pressure above, so as to block the diameter of the water spray pipe 103, reduce the water outlet diameter of the water spray pipe 103, so as to increase the internal pressure of the transfer box 101, so as to ensure that the water pressure sprayed by the water spray pipe 103 is at the required size, and facilitate the equipment to stably aim at the fire source for fire extinguishing work;

[0053] If the power supply at the fire source location is not completely cut off, the current will be transmitted along with the water flow, so that the immersion wire 403 is charged, which will make the electromagnet 402 work, so as to attract the second electrode 501, so that the second electrode 501 is connected to the first electrode 404, and the current on the power supply wire 405 is transmitted to the flexible wire 502, so as to supply power to the alarm device 503, so that the alarm device 503 alarms, which is convenient for the staff to cut off the power in time, so as to protect the electrical appliances at the fire extinguishing point and avoid secondary damage to the electrical equipment caused by the water flow conducting electricity.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
