[0002] Vacuum energy storage devices can effectively reduce energy loss and improve energy storage efficiency and stability by operating energy storage components, such as flywheels and superconducting magnets, in a vacuum environment.

[0003] The existing vacuum chambers do not have an alarm function during use. When a leak occurs in the vacuum chamber, the staff cannot detect it in time, which affects the normal use of the vacuum energy storage device.

[0004] Therefore, we urgently need to provide a vacuum cavity structure for a vacuum energy storage device. Utility Model Content

[0009] Preferably, the first metal plate and the second metal plate are connected to the positive and negative terminals of the power supply respectively via wires. The alarm is electrically connected to the power supply. When air leakage occurs inside the vacuum chamber, the pressure inside the vacuum chamber gradually increases. At this time, the air pressure pushes the sealing piston, causing the first metal plate to move upward and contact the second metal plate, so that the power supply is turned on to supply power to the alarm, thereby causing the alarm to sound and reminding the staff to deal with it in time.

[0010] Preferably, the second metal sheet has an inner ring, and the insulating rubber is fixedly installed on the inner ring to prevent the voltage regulating spring from contacting the second metal sheet, which would cause the power to be turned on and cause the alarm mechanism to be triggered falsely.

At the same time, the guide plate guides the flow of coolant.

[0013] Preferably, the cooling end of the semiconductor cooler is located inside the cooling box, and the heating end is located outside the cooling box.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Due to the limitations of current technology, when air leaks occur in the vacuum chamber, operators cannot detect them in a timely manner, thus affecting the normal operation of the vacuum energy storage device. Please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides a vacuum chamber structure for a vacuum energy storage device, which can issue an alarm when the vacuum chamber leaks, reminding personnel to handle the situation promptly. The vacuum chamber structure of this vacuum energy storage device includes a vacuum chamber 1 and a support 2. The support 2 is fixedly installed on the front and rear sides of the vacuum chamber 1. An auxiliary device is installed inside the vacuum chamber 1, including an alarm mechanism and a cooling mechanism.

[0026] The alarm mechanism is located at the top of the vacuum chamber 1, and the cooling mechanism is located inside the vacuum chamber 1.

[0027] The alarm mechanism includes a sealed box 301, a sealed piston 302, a first metal plate 303, a second metal plate 304, an insulating rubber sheet 305, a threaded rod 306, a pressure plate 307, a pressure adjusting spring 308, a power supply 309, and an alarm 310. The sealed box 301 is fixedly installed on the top right side of the vacuum chamber 1. The sealed piston 302 is movably installed inside the lower end of the sealed box 301. The first metal plate 303 is fixedly installed on the top of the sealed piston 302. The first metal plate 303 and the second metal plate 304 are connected to the positive and negative terminals of the power supply 309 respectively via wires. The alarm 310 is connected to the power supply 309. 9. Electrical connection: When air leakage occurs inside vacuum chamber 1, the pressure inside vacuum chamber 1 gradually increases. At this time, the air pressure pushes the sealing piston 302, causing metal plate one 303 to move upward and contact metal plate two 304, thus connecting the power supply 309 to power the alarm 310, causing the alarm 310 to sound an alarm to remind the staff to deal with it in time. Metal plate two 304 is fixedly installed inside the sealed box 301, located above metal plate one 303. Insulating rubber 305 is fixedly installed on the inner wall of metal plate two 304. Metal plate two 304 has an inner ring, and the insulating rubber 305 is fixedly installed on it. Installed on the inner ring, to prevent the pressure adjusting spring 308 from contacting the metal sheet 304, which could cause the power supply 309 to be turned on and trigger the alarm mechanism falsely. The threaded rod 306 is threadedly connected to the inside of the upper end of the sealing box 301. By rotating the threaded rod 306, the pressure plate 307 moves up and down, thereby adjusting the pre-compression of the pressure adjusting spring 308 and thus adjusting the elastic force of the pressure adjusting spring 308, achieving pressure adjustment of the pressure plate 307 by the pressure adjusting spring 308. The pressure plate 307 is rotatably connected to the bottom of the threaded rod 306, and the pressure adjusting spring 308 is fixedly installed on the metal sheet 303 and... Between the pressure plates 307, the sensitivity of the alarm mechanism is adjusted by changing the pre-compression of the pressure regulating spring 308. When the pre-compression is small, the sealing piston 302 can more easily drive the metal plate 303 to move upward. When the pre-compression is large, the sealing spring 302 needs to overcome the elastic force of the pressure regulating spring 308 to drive the metal plate 303 to move upward, thereby realizing the adjustment of the sensitivity of the alarm mechanism. The power supply 309 is installed on the top of the vacuum chamber 1, and the alarm 310 is installed on the top of the power supply 309. The alarm 310 is model YS-01H, and emits a buzzer sound and voice alarm after being powered on.

[0028] Example 2:

[0029] Based on Example 1, please refer to Figures 1-4To prevent the temperature inside the vacuum chamber 1 from rising during operation, this device is also equipped with a cooling mechanism. The cooling mechanism includes a guide plate 401, a housing 402, a first pump body 403, an inlet pipe 404, an outlet pipe 405, a cooling tank 406, a semiconductor cooler 407, a second pump body 408, and a return pipe 409. The guide plate 401 is fixedly installed inside the vacuum chamber 1. The vacuum chamber 1 has an internal cavity, and the guide plate 401 is fixedly installed inside the cavity. 01 provides support for vacuum chamber 1, preventing it from being pressured by external atmospheric pressure and causing the outer wall to dent. Simultaneously, the guide plate 401 guides the flow of coolant. The housing 402 is installed on the left side of the back of vacuum chamber 1. Pump body 403 is installed on top of housing 402. One end of the inlet pipe 404 is connected to the output end of pump body 403, and the other end is connected to the top of vacuum chamber 1. The outlet pipe 405 is connected to the right side of the bottom of vacuum chamber 1. The inlet pipe 404 is positioned away from pump body 403. The end of the water outlet pipe 405 away from the cooling box 406 is connected to the cavity opened in the vacuum chamber 1, allowing the coolant to flow along the guide plate 401 inside the cavity to cool the vacuum energy storage device. Simultaneously, the used coolant can flow along the water outlet pipe 405 into the cooling box 406 for further cooling. The cooling box 406 is connected to the left end of the water outlet pipe 405. A semiconductor cooler 407 is installed inside the cooling box 406. The semiconductor cooler 407 is a TEC1-12705 model. The cooling end of 407 is located inside the cooling box 406, and the heating end is located outside the cooling box 406. The surface of the heating end is provided with heat dissipation fins to improve the stability of the operation of the semiconductor cooler 407 and realize the continuous cooling of the coolant in the cooling box 406. Pump body 2 408 is fixedly installed on the back of the cooling box 406. Pump body 1 403 and pump body 2 408 are model ZLB-70. One end of the return pipe 409 is connected to the output end of pump body 2 408 and the other end is connected to the front of the box 402.

[0030] During use, when the internal temperature of vacuum chamber 1 is too high, pump body 403 is activated to allow the coolant in housing 402 to flow into the cavity of vacuum chamber 1 through inlet pipe 404. At the same time, the coolant flows along guide plate 401 and exchanges heat with vacuum chamber 1 to cool the vacuum energy storage device. Subsequently, the coolant flows into cooling tank 406 through outlet pipe 405. After the semiconductor cooler 407 cools the coolant in cooling tank 406, pump body 408 sends the coolant back into housing 402 to achieve the circulation of coolant. When vacuum chamber 1 leaks air, the internal pressure gradually increases. At this time, the air pressure pushes the sealing piston 302 to move metal plate 303 upward to contact metal plate 304, so that power supply 309 is turned on to supply power to alarm 310, thereby causing alarm 310 to sound and reminding staff to deal with it in time.
