For example, a water pump primarily pumps water from a low level to a higher level. A "heat pump" is a device that extracts low-level thermal energy from natural sources like air, water, or soil and, by using electrical energy to perform work, produces usable, high-level thermal energy.

[0003] For example, a Chinese utility model patent (CN216845210U) discloses a heat pump based on waste heat recovery and utilization, which records: "A recovery cylinder is provided at the large-aperture air outlet of the heat pump, and a stepped pipe and an annular pipe are provided inside the recovery cylinder. A condenser is provided in a circular array at the bottom of the annular pipe. Cooling water of a certain depth is supplied between the stepped pipe and the recovery cylinder through the water inlet pipe. A water pump is provided on one side of the annular pipe, and the condenser draws cooling water. After the air with a certain amount of heat is discharged from the air outlet, it contacts the condenser for heat exchange, and the residual heat in the air can be stored and utilized by the cooling water." It also records: "The air discharged from the air outlet of the air source heat pump in the prior art still has a certain amount of heat. Directly discharging the air with a certain amount of heat into the outside air will cause serious waste of residual heat energy in the air." Technical problem.

[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0030] As described in the background art, the air discharged from the air outlet of the air source heat pump in the prior art still has a certain amount of heat. Directly discharging the air with a certain amount of heat into the outside air will cause serious waste of residual heat energy in the air.

[0031] In order to solve this technical problem, the utility model provides a waste heat recovery and utilization device, which is used for waste heat utilization.

[0032] Specifically, please refer to Figure 1-Figure 7 , the waste heat recovery and utilization device specifically includes:

[0033] A chassis 1 is provided, wherein a generator box 14 is fixed inside the chassis 1. A transmission shaft 10 is rotatably connected to the inside of the generator box 14. The transmission shaft 10 extends to the outside of the generator box 14. One end of the transmission shaft 10 located inside the generator box 14 is fixedly connected to a first gear 11. An electromagnetic generator 13 is also fixed inside the generator box 14. A second gear 12 is fixed to the rotating shaft of the electromagnetic generator 13. The first gear 11 is meshed with the second gear 12.

[0034] The hot air box 7 is located inside the chassis 1 and at a position away from one end of the power generation box 14. An exhaust port 2 and an air inlet 3 are fixed to the outside of the chassis 1 and at a position corresponding to the hot air box 7. The exhaust port 2 and the air inlet 3 are arranged parallel to each other up and down. The exhaust port 2 and the air inlet 3 are both connected to the inside of the hot air box 7. The hot air box 7 is fixedly connected to the chassis 1. A driving shaft 9 is rotatably connected to the inside of the hot air box 7. The driving shaft 9 is located on the outside of one end of the hot air box 7 and is detachably connected to a power fan 8. The end of the driving shaft 9 away from the power fan 8 extends to the outside of the hot air box 7. The end of the driving shaft 9 extending to the outside of the hot air box 7 is movably connected to the transmission shaft 10 through a connecting mechanism 15.

[0035] The waste heat recovery and utilization device provided by the present invention can prevent the driving shaft 9 from directly contacting the hot air during operation through the structural design inside the hot air box 7, and the structural design of the power fan 8 can be used to disassemble and clean the power fan 8 when there is too much dirt, thereby improving work efficiency.

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 1-6 A waste heat recovery and utilization device includes: a chassis 1, a power generation box 14 is fixed inside the chassis 1, a transmission shaft 10 is rotatably connected to the inside of the power generation box 14, the transmission shaft 10 extends to the outside of the power generation box 14, and one end of the transmission shaft 10 located inside the power generation box 14 is fixedly connected to a first gear 11, an electromagnetic generator 13 is also fixed inside the power generation box 14, a second gear 12 is fixed on the rotating shaft of the electromagnetic generator 13, and the first gear 11 is meshed with the second gear 12;

[0039] Hot air box 7, the hot air box 7 is located inside the chassis 1 and away from one end of the power generation box 14. The exhaust port 2 and the air inlet 3 are fixed to the outside of the chassis 1 and at the position corresponding to the hot air box 7. The exhaust port 2 and the air inlet 3 are arranged in parallel up and down. The exhaust port 2 and the air inlet 3 are both connected to the inside of the hot air box 7. The hot air box 7 is fixedly connected to the chassis 1. The hot air box 7 is rotatably connected to the inside of the hot air box 7. The driving shaft 9 is located on the outside of one end of the hot air box 7 and is detachably connected to the power fan 8. The driving shaft 9 extends to the outside of the hot air box 7 away from the end of the power fan 8. The driving shaft 9 One end extending to the outside of the hot air box 7 is movably connected to the drive shaft 10 through a connecting mechanism 15; further, in order to facilitate cleaning and maintenance of the inside of the hot air box 7, one end of the hot air box 7 is rotatably connected to a cleaning flap 16, and the end of the cleaning flap 16 close to the hot air box 7 is fixedly connected to an isolation ring 17, and an isolation ring 2 18 is fixedly connected to the position inside the hot air box 7 corresponding to the isolation ring 17. The isolation ring 17 and the isolation ring 2 18 protect the internal structure when the cleaning flap 16 and the hot air box 7 are closed, thereby reducing the contact between the power fan 8 and the driving shaft 9 and the hot air.

[0040] It can be seen that when in use, the air discharged from the air outlet of the air source heat pump is connected to the air inlet 3, the gas enters the hot air box 7 through the air inlet 3 and causes the power fan 8 to rotate, thereby driving the driving shaft 9 to rotate. The driving shaft 9 cooperates with the connecting mechanism 15 to rotate the transmission shaft 10 and then drives the first gear 11 to rotate and the second gear 12 to rotate, thereby causing the electromagnetic generator 13 to generate electricity.

[0041] Furthermore, the power fan 8 includes a threaded ring 20, which is sleeved on the outside of the driving shaft 9. A plurality of fixed blocks 21 are provided at one end of the threaded ring 20, and a spring 22 is fixedly connected between the plurality of fixed blocks 21. The end of the threaded ring 20 close to the fixed block 21 is threadedly connected to a rotating sleeve 19, and a plurality of fan blades 23 are fixedly connected to the outside of the threaded ring 20.

[0042] It can be seen that when the power fan 8 needs to be cleaned, the cleaning flap 16 can be opened and the rotating sleeve 19 can be rotated. The fixing block 21 will lack the squeezing of the rotating sleeve 19 and be pushed outward by the spring 22, thereby releasing the clamping of the driving shaft 9 so that the power fan 8 as a whole can be removed from the driving shaft 9. When the cleaning is completed, it is only necessary to put the threaded ring 20, the fixing block 21 and the spring 22 back to the outside of the driving shaft 9, and put the rotating sleeve 19 on the threaded ring 20 and rotate it in the opposite direction. The rotating sleeve 19 will squeeze the fixing block 21 while rotating to clamp the driving shaft 9, thereby completing the fixation of the power fan 8 and the driving shaft 9.

[0043] Furthermore, in order to facilitate cleaning and maintenance of the interior of the device, maintenance door 1 5 and maintenance door 2 6 are respectively provided on the outside of the chassis 1 and at positions corresponding to the power generation box 14 and the hot air box 7.

[0044] Example 2:

[0045] The waste heat recovery device provided in Example 1 is further optimized. Specifically, Figure 7 As shown, further, the connecting mechanism 15 includes a rotating head 24, which is sleeved on the outside of the driving shaft 9 and is slidingly connected to the driving shaft 9; further, in order to enable the rotating head 24 to follow the rotation when the driving shaft 9 rotates, a follower block 27 is fixed at the end of the driving shaft 9 and at the position of the rotating head 24; one end of the rotating head 24 is movably connected to a rotating seat 25, and the rotating seat 25 is fixedly connected to the transmission shaft 10, and a shift fork 26 is movably connected to the outside of the rotating head 24, and the upper end of the shift fork 26 extends to the outside of the chassis 1, and the shift fork 26 is rotatably connected to the chassis 1, and a handle is fixedly provided on the end of the shift fork 26 extending to the outside of the chassis 1.

[0046] It can be seen that when the device is not needed to generate electricity, the handle can be pushed to drive the fork 26 to move, so that the rotating head 24 movably connected to the fork 26 follows the movement, so that the rotating head 24 and the rotating seat 25 are separated, so that the transmission shaft 10 no longer rotates with the driving shaft 9, thereby stopping the device from running.

[0047] Example 3:

[0048] The waste heat recovery device provided in Example 1 is further optimized. Specifically, Figure 1 As shown, further, in order to facilitate the movement and adjustment of the placement of the device, moving wheels 4 are fixedly connected to the four end corners below the chassis 1.
