Description

Technical Field

[0001] The utility model belongs to the technical field of electric heat storage and relates to a heat storage body, in particular to a clutch type heat storage body structure. Background Art

[0002] Solid thermal storage is a thermal storage method that uses low-price electricity periods to convert electrical energy into thermal energy and store it in solid thermal storage materials. When heat is needed, the heat is released through necessary heat extraction methods. The advantages of solid electric thermal storage include: high thermal storage temperature, small space occupation, fast thermal storage and release efficiency, stable performance, etc. It can be widely used in regional heating, power plant peak regulation, and industrial production heat.

[0003] However, the heat storage bodies of the solid heat storage system are all fixedly arranged, and usually a structure in which multiple heat storage bodies are closely fitted is adopted. Hot air passes through one side of all the heat storage bodies to absorb the heat released by the heat storage bodies. When in use, the heat release of the heat storage bodies is slow and the heating efficiency is low. There are also heat storage body structures in which multiple heat storage bodies are arranged at equal distances, and hot air can pass between the multiple heat storage bodies. Although this improves the heating efficiency during use, this structure will cause heat loss of the heat storage body when the heat storage body is powered on for heating, thereby increasing energy consumption.

[0020] A heating tube 6 runs through the middle of the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4. Both ends of the heating tube 6 are connected to a power source to electrically heat the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4 respectively in the heat storage state.

[0021] like Figure 3-4 As shown, a first piston cavity 51 is provided at the top of the first heat storage body 2 and the top of the second heat storage body 3, a second piston cavity 52 is provided at the bottom of the third heat storage body 4 and the bottom of the second heat storage body 3, and the air pressure regulating assembly 5 includes a first piston 53 slidably installed in the first piston cavity 51, a second piston 54 slidably installed in the second piston cavity 52, and a piston rod 55 connected between the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4. The first piston 53 is sealedly connected to the inner wall of the first piston cavity 51, the second piston 54 is sealedly connected to the inner wall of the second piston cavity 52, and both ends of the piston rod 55 are fixedly connected to the first piston 53 and the second piston 54 respectively.

[0022] The first piston chamber 51 and the second piston chamber 52 on the second heat storage body 3 are connected to each other. The first piston 53, the second piston 54 and the piston rod 55 have a through vent hole 56 in the middle. The bottom of the first heat storage body 2 is provided with an air pipe 57 connected to the first piston chamber 51.

[0023] Two opposite first limit plates 58 are provided at the bottom of the first piston chamber 51 and the top of the second piston chamber 52, and two opposite second limit plates 59 are provided at the top of the first piston chamber 51 and the bottom of the second piston chamber 52 to limit the stroke of the first piston 53 and the second piston 54 respectively, and when the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4 are tightly fitted, an air gap is reserved at the bottom of the first piston chamber 51 and the top of the second piston chamber 52 respectively.

[0024] A plurality of second heat storage bodies 3 are provided, and two adjacent second heat storage bodies 3 are connected to each other via an air pressure regulating component 5 .

[0025] A spring 7 is connected between the first heat storage body 2 , the second heat storage body 3 , and the third heat storage body 4 , and the limit elastic force of the spring 7 is less than the gravity of the first heat storage body 2 / the second heat storage body 3 / the third heat storage body 4 .

[0026] When the utility model is working, when the heat storage body is in the heat storage state, the heating tube 6 is energized to heat the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4 respectively. At this time, the third heat storage body 4, the second heat storage body 3, and the first heat storage body 2 are closely attached to each other under the action of gravity, reducing the contact area between the heat storage body and the environment, thereby reducing heat loss and reducing energy consumption; when the heat storage body is in the heat release state, the power supply of the heating tube 6 is disconnected to stop heating, and gas is introduced into the first piston chamber 51 on the first heat storage body 2 through the gas pipe 57, and the gas passes through the gas pipe 57.

The piston rod 55 between the first piston 53 and the second piston 54 separates the first heat storage body 2, the second heat storage body 3, and the third heat storage body 4, forming an air flow channel between adjacent heat storage bodies, increasing the contact area between the heat storage bodies and the environment, so that the air flow passing through the heat storage bodies can fully absorb the heat on the heat storage bodies, thereby improving the heating efficiency and effect of the air flow when the heat storage bodies release heat; when the heat storage bodies have completed heat release, the high-pressure gas in the first piston chamber 51 and the second piston chamber 52 is released through the air pipe 57, and the third heat storage body 4 and the second heat storage body 3 fall under the action of gravity. When the piston rod 55 is in close contact with the first heat storage body 2, the third heat storage body 4 and the second heat storage body 3 are prevented from being damaged during the falling process by the buffering effect of the spring 7. At this time, the two ends of the piston rod 55 are respectively retracted into the first piston cavity 51 and the second piston cavity 52, and the first piston 53 and the second piston 54 are reset in the first piston cavity 51 and the second piston cavity 52 respectively, and are limited by the first limiting plate 58 to reserve an air gap at the bottom of the first piston cavity 51 and the top of the second piston cavity 52, so as to facilitate the inflation of air into the first piston cavity 51 and the second piston cavity 52.
