[0002] Since the beginning of the last century, the energy crisis around the world has triggered various industries to think about energy conservation. Users in various industries have proposed the concept of air conditioning exhaust energy recovery, which directly gave rise to the development of the gas-to-gas energy heat recovery device manufacturing industry. For large-displacement air conditioning exhaust systems, it is advisable to install energy recovery devices. In the air-conditioning system, for the comfort of personnel and smooth ventilation, it is necessary to consider introducing fresh air from the outside and exhausting the turbid air in the room. The proportion of fresh air load in the cooling load is relatively large. Therefore, it is necessary to add a suitable energy recovery device between the exhaust side and the fresh air side, which directly leads to the rapid development of the heat recovery industry.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a chain-driven heat recovery wheel, comprising a frame 1, a wheel body 4 is rotatably connected inside the frame 1, a plurality of connecting holes 2 are opened inside the frame 1, and a transmission mechanism is arranged inside the frame 1;

[0027] The transmission mechanism includes two mounting columns 7, a movable plate 8, a transmission wheel 10, a chain 6 and a plurality of limit blocks 12. An active cavity 5 begins to be formed inside the frame 1. The mounting column 7 is fixedly mounted inside the active cavity 5. The movable plate 8 is slidably connected to the side wall of the mounting column 7. A first spring is mounted on the top of the movable plate 8. The transmission wheel 10 is mounted on the top of the movable plate 8. The transmission wheel 10 is transmission-connected to the rotating wheel body 4 through the chain 6. The limit blocks 12 are mounted inside the mounting column 7. The first spring is fixedly mounted between the top of the movable plate 8 and the inner wall of the active cavity 5. The first spring is located on the side wall of the mounting column 7.

[0028] It should be noted that, by setting the mounting column 7, the movable plate 8 can be made to slide inside the movable cavity 5, so that the transmission wheel 10 can slide inside the movable cavity 5. By setting the first spring, the movable plate 8 can be pushed downward. When the chain 6 is not loosened and lengthened, the movable plate 8 is fixed by the pulling of the limit block 12, the first spring and the chain 6. When the chain 6 becomes loose, the first spring pushes the movable plate 8 so that the movable plate 8 pushes a group of limit blocks 12 into the mounting groove 11 through the groove 13, so that the movable plate 8 is located between the other group of limit blocks 12, thereby ensuring the transmission effect of the chain 6.

[0029] In some embodiments, Figure 3 As shown, a servo motor 9 is fixedly mounted on the top of the movable plate 8 , and a transmission wheel 10 is fixedly mounted on the output end of the servo motor 9 .

[0030] It should be noted that, by providing the servo motor 9 , the driving wheel 10 can be driven to rotate by the rotation of the servo motor 9 , thereby driving the rotating wheel body 4 to rotate through the chain 6 .

[0032] It should be noted that by setting a second spring, the limit block 12 can be pushed to one side, so that the limit block 12 can limit the movable plate 8. When the chain 6 becomes loose, the first spring pushes the movable plate 8 so that the movable plate 8 pushes a group of limit blocks 12 into the installation groove 11 through the groove 13, so that the movable plate 8 is located between the other group of limit blocks 12, thereby ensuring the transmission effect of the chain 6.

[0033] Example 2

[0034] In some embodiments, Figure 1 As shown, a filter screen 3 is fixedly installed inside the communicating hole 2.

[0035] It should be noted that, by providing the filter 3 inside the connecting hole 2 , it is possible to prevent external dust or debris from entering the frame 1 , thereby preventing the operation of the wheel body 4 from being affected.

[0036] The rotating wheel body 4 and the servo motor 9 of the present invention are well-known components and will not be described in detail herein.

[0037] Working principle: When in use, the servo motor 9 drives the transmission wheel 10 to rotate, so that the chain 6 can drive the wheel body 4 to rotate, so that the wheel body 4 returns air to the room. When the chain 6 is not loosened or lengthened, the movable plate 8 is fixed by the pull of the limit block 12, the first spring and the chain 6. When the chain 6 is loose, the first spring pushes the movable plate 8 so that the movable plate 8 pushes a group of limit blocks 12 into the installation groove 11 through the groove 13, so that the movable plate 8 is located between the other group of limit blocks 12, thereby ensuring the transmission effect of the chain 6.
