Description

Technical Field

[0001] This invention relates to the field of power plant energy storage cooling technology, and more particularly to a power plant energy storage cooling water circulation device. Background Technology

[0002] Currently, thermal power generation mainly uses coal combustion to heat water, producing steam. This steam converts chemical energy into heat energy, which drives the impeller and rotor to rotate, converting the heat energy into kinetic energy. In conjunction with the stator cutting magnetic field lines, mechanical energy is converted into electrical energy. Therefore, thermal power generation produces a large amount of high-temperature steam. To avoid affecting the ambient temperature and to protect the exhaust pipes, the steam needs to be cooled before being discharged. However, existing power plant cooling equipment mostly surrounds the pipes with cooling pipes. While this protects the pipes, it cannot guarantee effective heat dissipation of the steam, making it difficult to avoid affecting the ambient temperature. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a power plant energy storage cooling water circulation device to solve the above-mentioned shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a power plant energy storage cooling water circulation device, comprising an exhaust pipe, a housing fixed to the outside of the exhaust pipe, a first cooling pipe and a second cooling pipe respectively inserted into the inner and outer sides of the exhaust pipe, the first cooling pipe and the second cooling pipe being interconnected, a power chamber and a heat dissipation chamber being respectively opened inside the housing, the second cooling pipe being interconnected with the power chamber, the first cooling pipe being interconnected with the heat dissipation chamber, a piston being slidably installed in the power chamber, and a cooling fan being fixed to the outside of the heat dissipation chamber.

[0005] Furthermore, the outer ends of the first cooling pipe and the second cooling pipe are respectively connected to a first conduit and a second conduit. A first through hole and a second through hole are opened on both sides of one end face of the power cavity. The two ends of the second conduit are respectively connected to the first through hole and the second through hole. A fifth through hole connected to the first conduit is opened on one side of the heat dissipation cavity. A third through hole and a fourth through hole communicating with the heat dissipation cavity are opened on both sides of the other end face of the power cavity.

[0006] Furthermore, a first sealing plate and a second sealing plate are rotatably mounted on the inner end faces of the first through hole and the second through hole, respectively, and a third sealing plate and a fourth sealing plate are rotatably mounted on the outer end faces of the third through hole and the fourth through hole, respectively.

[0007] Furthermore, a reciprocating screw that is threadedly engaged with the center of the piston is rotatably installed inside the power chamber, and a rotating rod that meshes with the output shaft of the cooling fan and the reciprocating screw is rotatably installed between them via a bevel gear set.

[0008] Furthermore, multiple heat dissipation passages are equally spaced on one side of the heat dissipation cavity, and both ends of the heat dissipation passages are connected to the outside, and the positions of the heat dissipation passages are matched with those of the heat dissipation fan.

[0009] Through the above design scheme, the present invention can bring the following beneficial effects:

[0010] 1. The power plant energy storage cooling water circulation device proposed in this invention is equipped with a first cooling pipe and a second cooling pipe. Through a piston, water can be circulated and guided in the first cooling pipe, the second cooling pipe, the power chamber and the heat dissipation chamber. With the help of the heat dissipation fan, the water inside the heat dissipation chamber can be dissipated, thereby circulating and dissipating heat on both sides of the exhaust pipe. It can also dissipate heat from the exhaust pipe and the water vapor inside the exhaust pipe at the same time, thereby ensuring heat dissipation efficiency.

[0011] 2. The power plant energy storage cooling water circulation device proposed in this invention is equipped with a rotating rod. When the motor inside the cooling fan drives the cooling fan blades to rotate, it can simultaneously drive the reciprocating screw to rotate. Through the threaded engagement between the reciprocating screw and the piston, the piston can be driven to reciprocate within the power chamber. With the cooperation of four sealing plates, the water circulation can be promoted, thereby improving the cooling efficiency. Attached Figure Description

Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0019] Reference Figure 1-5 A power plant energy storage cooling water circulation device includes an exhaust pipe 1, a housing 2 fixed to the outside of the exhaust pipe 1, a first cooling pipe 5 and a second cooling pipe 3 respectively inserted into the inner and outer sides of the exhaust pipe 1, the first cooling pipe 5 and the second cooling pipe 3 being interconnected, a power chamber 8 and a heat dissipation chamber 9 respectively opened inside the housing 2, the second cooling pipe 3 being connected to the power chamber 8, the first cooling pipe 5 being connected to the heat dissipation chamber 9, a piston 10 being slidably installed in the power chamber 8, and a cooling fan 19 being fixed to the outside of the heat dissipation chamber 9.

[0020] Specifically, a cooling fan 19 is installed to guide air into the cooling chamber 9, which can dissipate heat from the moisture inside the cooling chamber 9. Through the piston 10 moving inside the power chamber 8, in conjunction with air pressure, the moisture can be driven to circulate in the first cooling pipe 5, the second cooling pipe 3, the power chamber 8 and the cooling chamber 9, thereby continuously cooling the inside and outside of the exhaust pipe 1. This not only cools the exhaust pipe 1 to ensure stable operation of the exhaust pipe 1, but also cools the water vapor inside the exhaust pipe 1 to avoid affecting the surrounding ambient temperature.

[0021] The outer ends of the first cooling pipe 5 and the second cooling pipe 3 are respectively connected to the first conduit 7 and the second conduit 6. The inner end face of the power chamber 8 is provided with a first through hole 14 and a second through hole 13 on both sides. The two ends of the second conduit 6 are respectively connected to the first through hole 14 and the second through hole 13. The inner side of the heat dissipation chamber 9 is provided with a fifth through hole 4 connected to the first conduit 7. The other end face of the power chamber 8 is provided with a third through hole 15 and a fourth through hole 16 communicating with the inner cavity of the heat dissipation chamber 9. The inner end faces of the first through hole 14 and the second through hole 13 are respectively rotatably installed with a first sealing plate 131 and a second sealing plate 141. The outer end faces of the third through hole 15 and the fourth through hole 16 are respectively rotatably installed with a third sealing plate 151 and a fourth sealing plate 161. The power chamber 8 is rotatably installed with a reciprocating screw 11 that is threaded in the middle of the piston 10. The output shaft 18 of the cooling fan 19 and the reciprocating screw 11 are rotatably installed with a rotating rod 17 that meshes with both through a bevel gear set.

[0022] Specifically, when the internal motor of the cooling fan 19 is started, driving the outer cooling fan blades to rotate, the reciprocating screw 11 can be driven to rotate within the power chamber 8 via the rotating rod 17 and two sets of bevel gears. Under the restriction of the movement direction of the piston 10 by the power chamber 8, the rotating reciprocating screw 11, through its threaded engagement with the piston 10, can drive the piston 10 to reciprocate within the power chamber 8. When the piston 10 moves to one side, the air pressure inside one side of the power chamber 8 increases, while the air pressure inside the other side of the power chamber 8 decreases, thereby opening the second sealing plate 141 and the third sealing plate 151 and closing the first sealing plate 131. Conversely, when the piston 10 moves to the other side, the opening and closing of the four sealing plates are reversed. In this manner, water inside the first cooling pipe 5 and the second cooling pipe 3 is continuously introduced into the power chamber 8 through the first through hole 14, the second through hole 13 and the second conduit 6. Then, water inside the power chamber 8 is injected into the heat dissipation chamber 9 through the third through hole 15 and the fourth through hole 16. As the water inside the heat dissipation chamber 9 increases, water inside the heat dissipation chamber 9 can be injected into the second cooling pipe 3 and the first cooling pipe 5 through the first conduit 7. In this way, the circulation and guidance of water is completed.

[0023] Multiple heat dissipation cavities 12 are equally spaced on one side of the heat dissipation cavity 9. Both ends of the heat dissipation cavities 12 are connected to the outside, and the positions of the heat dissipation cavities 12 and the heat dissipation fan 19 are matched.

[0024] Specifically, when the cooling fan 19 is started, the fan blades at the front end of the cooling fan 19 can guide the outside air to pass through the cooling cavity 12. The cooling cavity 12 is set up to increase the contact area between the moisture inside the cooling cavity 9 and the outside air, thereby improving the heat dissipation efficiency.
