Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a control device for a cogeneration unit, including a support frame 1, fixed blocks 2 are fixedly installed at the four corners of the top of the support frame 1, and the number of the fixed blocks 2 is four. A water tank 3 is fixedly installed on the top of the four fixed blocks 2, and a rotating rod 4 is movably sleeved on the middle part of the right side of the water tank 3. The left end of the rotating rod 4 passes through the water tank 3 and extends to the outside of the left side of the water tank 3. The outer surface of the rotating rod 4 is fixedly sleeved with a first long plate 5 located on the left side of the inside of the water tank 3, and the outer surface of the rotating rod 4 is fixedly sleeved with a second long plate 7 located on the right side of the inside of the water tank 3. The interior of the second long plate 7 is movably sleeved with the rotating rod 4. The interior of the rotating rod 4 is connected, and the interior of the right side of the No. 1 long board 5 is fixedly sleeved with a high-temperature gas pipeline body 6. There are two high-temperature gas pipeline bodies 6, and the other ends of the two high-temperature gas pipeline bodies 6 pass through the left side of the No. 2 long board 7 and extend to the interior of the No. 2 long board 7. The interior of the left side of the rotating rod 4 is fixedly sleeved with an air intake pipe 8, and the upper and lower sides of the right end of the air intake pipe 8 are fixedly installed with connecting pipes 23. The other end of the connecting pipe 23 passes through the rotating rod 4 and the No. 1 long board 5 and extends to the interior of the No. 1 long board 5. The right end of the rotating rod 4 is connected to a driving component for driving the rotating rod 4 to rotate.

[0021] When the operator starts the drive assembly, the drive assembly will drive the rotating rod 4 to rotate as a whole, which will cause the two high-temperature gas pipe bodies 6 to rotate, so that the hot gas inside the high-temperature gas pipe body 6 can fully contact the water source inside the water tank 3, thereby improving the effect of absorbing the waste heat of the high-temperature gas generated by the cogeneration machine.

[0022] Among them, the driving assembly includes an output motor 10, which is fixedly mounted on the right end of the support frame 1. The other end of the output shaft of the output motor 10 is fixedly sleeved with a rotating shaft 11, and the outer surface of the rotating shaft 11 is fixedly sleeved with a driving wheel 12. The outer surface of the right end of the rotating rod 4 is fixedly sleeved with a driven wheel 9, and the driven wheel 9 is connected to the driving wheel 12 through a belt 13. The outer surface of the rotating rod 4 is fixedly sleeved with a No. 1 heat conducting plate 14 located inside the water tank 3, and the outer surface of the high-temperature gas pipeline body 6 is fixedly sleeved with a No. 2 heat conducting plate 15.

[0023] Due to the arrangement of the first heat conducting plate 14 and the second heat conducting plate 15 , heat conduction can be performed on the high temperature gas inside the rotating rod 4 and the high temperature gas pipe body 6 .

[0024] A valve 16 is fixedly installed in the middle of the bottom end of the water tank 3 , and the interior of the valve 16 is communicated with the interior of the water tank 3 .

[0025] Due to the setting of the valve 16 , the water in the water tank 3 can be discharged to the outside through the valve 16 .

[0026] A water injection pipe 17 is fixedly installed on the left side of the top of the water tank 3 , and the interior of the water injection pipe 17 is communicated with the interior of the water tank 3 .

[0027] The operator can inject water into the water tank 3 through the water injection pipe 17 .

[0028] Among them, a round rod 18 is fixedly sleeved inside the right side of the top of the water injection pipe 17, the top of the round rod 18 passes through the water injection pipe 17 and extends to the outside of the top of the water injection pipe 17, and a round cover 19 is movably sleeved on the outer surface of the round rod 18.

[0029] Due to the arrangement of the round cover 19 , the interior of the water tank 3 is sealed.

[0030] Among them, a circular groove 24 is opened on the left side of the top of the water injection pipe 17, and a pin 20 is movably installed inside the circular groove 24. A pull ring 21 is fixedly installed on the top of the pin 20. The outer surface of the pin 20 is movably sleeved with a spring 22 located at the top of the water injection pipe 17. The top of the spring 22 is fixedly connected to the bottom end of the pull ring 21, and the bottom end of the spring 22 is fixedly connected to the top of the water injection pipe 17.

[0031] Due to the arrangement of the latch 20 and the spring 22, the round cover 19 is fixed.

[0032] The working principle and use process of this utility model:

[0033] First, the operator pulls the pull ring 21 to release the latch 20 from fixing the round cover 19. At this time, the operator injects water into the water tank 3 through the water injection pipe 17. When the water injection is completed, the operator pulls the pull ring 21 and rotates it around the round rod 18 until the latch 20 is inserted into the round groove 24 again under the elastic recovery action of the spring 22, thereby fixing the round cover 19 again.

[0034] Then the operator injects high-temperature gas through the air intake pipe 8. At this time, the high-temperature gas will pass through the No. 1 long board 5, the high-temperature gas pipeline body 6, the No. 2 long board 7 and the rotating rod 4 in turn, and finally be discharged to the outside through the exhaust pipe 25. Then the operator starts the output motor 10, so that the rotating shaft 11 drives the driving wheel 12 to rotate, and then the driving wheel 12 drives the driven wheel 9 to rotate through the belt 13. At this time, the driven wheel 9 will drive the rotating rod 4 and the high-temperature gas pipeline body 6 to rotate together. At this time, the water inside the water tank 3 will be fully and evenly contacted with the high-temperature gas inside the high-temperature gas pipeline body 6, so that the waste heat recovery effect is good. When the operator needs to drain the water in the water tank 3, he only needs to open the valve 16. At this time, the water in the water tank 3 will be discharged to the outside through the valve 16.
