Description

Technical Field

[0001] This utility model relates to the field of rain shower system technology, and in particular to a power plant fire-fighting rain shower system. Background Technology

[0002] A power plant fire sprinkler system is an open-type automatic sprinkler system controlled by an automatic fire alarm system or transmission pipes. It automatically opens the sprinkler alarm valve and starts the water supply pump, supplying water to the open sprinkler heads to achieve rapid fire suppression. This system features a large water output and timely fire suppression, and is typically used in buildings and areas where fires spread rapidly and are highly dangerous, such as power plants and other industrial sites.

[0003] Fire sprinkler systems installed at power plant sites are generally open systems with vertically mounted sprinkler valves. Online testing alarm bells and devices are also located vertically. During online testing of the alarm bells and pressure alarm switches, the bottom test ball valve is opened for trial operation. After the test, water remains inside the pipes, especially at pipe bends, causing severe corrosion to the pipes, valves, and alarm bells. This frequently results in rust and damage to the internal bearings of the alarm bells, internal leakage in valves, and blockages inside the pipes, seriously affecting the normal and stable operation of the sprinkler valves. Therefore, this utility model proposes a fire sprinkler system for power plants to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a power plant fire sprinkler system. This system adds a tee pipe at the angle between the first and second pipelines, and connects a drip valve with a fitting. After the test, the remaining water is drained through the drip valve. During the test, high-pressure water can close the drip valve, ensuring the test proceeds normally and effectively eliminating corrosion damage to the sprinkler valve alarm, valves, and pipelines.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a power plant fire sprinkler system, including a first pipeline and a second pipeline, both of which are connected to a sprinkler valve system, and a tee pipe is connected between the first pipeline and the second pipeline, with a connector at the lower end of the tee pipe and a drip valve below the connector;

[0006] Both sides of the connector are provided with support arms, and both sets of support arms are rotatably provided with linkage arms. The linkage arms are driven to rotate by a driving component, and the lower end of the linkage arm is provided with a clamping plate, which is used to clamp the drip valve.

[0007] A further improvement is that the driving component includes a nut ring and a rotating ring. The nut ring is movably disposed on the outside of the joint, and the rotating ring is rotatably disposed on the outside of the nut ring. Guide arms are rotatably provided on both sides of the rotating ring, and one end of each of the two sets of guide arms is hinged to the upper end of the two sets of linkage arms respectively.

[0008] A further improvement is that an external thread is provided on the upper part of the outer side of the connector, and the nut ring is adapted to the external thread.

[0009] A further improvement is that an internal thread is provided on the lower inner side of the connector, and the drip valve is adapted to the internal thread.

[0010] A further improvement is that the clamping piece is arc-shaped, and the arc of the clamping piece matches the arc of the outer side of the drip valve. The inner side of the clamping piece is provided with anti-slip rubber.

[0011] A further improvement is that the tee pipe is provided with flanges on one side and at the top, and the tee pipe is connected to the first pipeline and the second pipeline respectively through the flanges.

[0012] A further improvement is that the lower end of the tee pipe is integrally formed with the connector, and the drip valve is connected to the first pipeline and the second pipeline through the connector and the tee pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adds a T-shaped pipe at the angle between the first and second pipelines, and connects a drip valve with a fitting. After the test, the residual water is drained through the drip valve. When the test is conducted, the high-pressure water can close the drip valve to ensure the test can proceed normally, effectively eliminating the corrosion and damage to the deluge valve alarm, valve, and pipeline.

[0015] 2. This utility model moves by rotating the nut ring in conjunction with the external thread, causing the rotating ring to rise and fall, thereby driving the guide arm to rotate, which in turn drives the linkage arm to rotate, so that the clamping plates on both sides hold the drip valve, improving the stability of the drip valve and preventing it from loosening.

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] Example 1

[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a power plant fire-fighting deluge system, including a first pipeline 1 and a second pipeline 2. Both the first pipeline 1 and the second pipeline 2 are connected to a deluge valve system 3. A tee pipe 4 is connected between the first pipeline 1 and the second pipeline 2. The lower end of the tee pipe 4 is provided with a connector 5, and a drip valve 6 is provided below the connector 5.

[0023] Both sides of the connector 5 are provided with support arms 7, and each set of support arms 7 is rotatably equipped with a linkage arm 8. The linkage arm 8 is driven to rotate by a driving component, and the lower end of the linkage arm 8 is provided with a clamping piece 9, which is used to clamp the drip valve 6. In use, a tee pipe 4 is added at the angle between the first pipeline 1 and the second pipeline 2, and a drip valve 6 is connected to the connector 5. After the test, the residual water is drained through the drip valve 6. When the test is conducted, the high-pressure water can close the drip valve 6 to ensure the normal conduct of the test and effectively eliminate the corrosion damage to the deluge valve alarm, valve, and pipeline.

[0024] The driving component includes a nut ring 11 and a rotating ring 12. The nut ring 11 is movably disposed on the outside of the connector 5, and the rotating ring 12 is rotatably disposed on the outside of the nut ring 11. Guide arms 13 are rotatably disposed on both sides of the rotating ring 12, and one end of each set of guide arms 13 is hinged to the upper end of each set of linkage arms 8. An external thread 10 is provided on the upper part of the outside of the connector 5, and the nut ring 11 is adapted to the external thread 10. In use, the nut ring 11 is rotated to move in conjunction with the external thread 10. Since the rotating ring 12 is rotatably connected to the nut ring 11, the rotating ring 12 does not rotate but only rises and falls, thereby driving the guide arms 13 to rotate, which in turn drives the linkage arms 8 to rotate, so that the clamping plates 9 on both sides clamp the drip valve 6, improving the stability of the drip valve 6 and preventing it from loosening.

[0025] The clamping plate 9 is arc-shaped, and the arc of the clamping plate 9 matches the arc of the outer side of the drip valve 6. The inner side of the clamping plate 9 is provided with anti-slip rubber. In use, rotating the nut ring 11, in conjunction with the external thread 10, moves the valve. Since the rotating ring 12 is rotatably connected to the nut ring 11, the rotating ring 12 will not rotate, but will only rise and fall, thereby driving the guide arm 13 to rotate, which in turn drives the linkage arm 8 to rotate, so that the clamping plates 9 on both sides clamp the drip valve 6. The anti-slip rubber increases the clamping friction and prevents the drip valve 6 from loosening.

[0026] The tee pipe 4 is provided with flanges 14 on one side and at the top, and the tee pipe 4 is connected to the first pipeline 1 and the second pipeline 2 respectively through the flanges 14. In use, the tee pipe 4 is connected to the first pipeline 1 and the second pipeline 2 respectively through the flanges 14, thereby connecting to the deluge valve system 3.

[0027] Example 2

[0028] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a power plant fire-fighting deluge system, including a first pipeline 1 and a second pipeline 2. Both the first pipeline 1 and the second pipeline 2 are connected to a deluge valve system 3. A tee pipe 4 is connected between the first pipeline 1 and the second pipeline 2. The lower end of the tee pipe 4 is provided with a connector 5, and a drip valve 6 is provided below the connector 5.

[0029] Both sides of the connector 5 are provided with support arms 7, and each set of support arms 7 is rotatably equipped with a linkage arm 8. The linkage arm 8 is driven to rotate by a driving component, and the lower end of the linkage arm 8 is provided with a clamping piece 9, which is used to clamp the drip valve 6. In use, a tee pipe 4 is added at the angle between the first pipeline 1 and the second pipeline 2, and a drip valve 6 is connected to the connector 5. After the test, the residual water is drained through the drip valve 6. When the test is conducted, the high-pressure water can close the drip valve 6 to ensure the normal conduct of the test and effectively eliminate the corrosion damage to the deluge valve alarm, valve, and pipeline.

[0030] The tee pipe 4 is provided with flanges 14 on one side and at the top, and the tee pipe 4 is connected to the first pipeline 1 and the second pipeline 2 respectively through the flanges 14. In use, the tee pipe 4 is connected to the first pipeline 1 and the second pipeline 2 respectively through the flanges 14, thereby connecting to the deluge valve system 3.

[0031] The lower inner side of the connector 5 is provided with an internal thread, which is adapted to the drip valve 6. The lower end of the tee pipe 4 is integrally formed with the connector 5 for greater stability. The drip valve 6 is connected to the first pipeline 1 and the second pipeline 2 through the connector 5 and the tee pipe 4. In use, the drip valve 6 is connected and fixed to the connector 5 through the internal thread, thereby connecting to the first pipeline 1 and the second pipeline 2.

[0032] The power plant's fire sprinkler system has an additional T-junction 4 installed at the angle between the first pipeline 1 and the second pipeline 2. A drip valve 6 is connected to the T-junction 5. After the test, the residual water is drained through the drip valve 6. When the test is conducted, the high-pressure water can close the drip valve 6 to ensure the test can proceed normally. This effectively eliminates the corrosion and damage to the sprinkler valve alarm, valve, and pipeline. At the same time, in order to prevent the drip valve 6 from loosening due to water pressure, the nut ring 11 is rotated, which moves in conjunction with the external thread 10. This moves the rotating ring 12 up and down, thereby driving the guide arm 13 to rotate. This, in turn, drives the linkage arm 8 to rotate, so that the clamping plates 9 on both sides hold the drip valve 6, improving the stability of the drip valve 6 and preventing it from loosening.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
