[0037] like Figure 1-4 As shown, an embodiment of the present invention provides a fuel cell waste heat recovery and utilization device, comprising two symmetrically arranged recovery and utilization structures, wherein an adjustment structure is connected to the recovery and utilization structure, and further comprising:

[0038] A support structure is provided, on which a water tank (not shown in the figure) filled with water is placed. An adjustment structure is slidably connected to the support structure.

[0045] Connector 24 is fixedly connected to the end of the fixing rod 18.

[0046] In this embodiment of the invention, the conveying pipe 23 is a telescopic pipe. Hot steam is conveyed to the inside of the conveying pipe 23 and then to the inside of the connecting seat 22, and finally reaches the inside of the heating plate 21 to heat the heating plate 21. At this time, the high temperature of the heating plate 21 can heat the water inside the water tank, so that the waste heat can be reasonably recovered and utilized.

[0047] like Figure 1 and Figure 4 As shown, in a preferred embodiment of this utility model, the adjustment structure includes:

[0048] The sliding sleeve 16 is slidably connected to the support structure. The sliding sleeve 16 is composed of a rectangular groove 161 and circular grooves 162 symmetrically distributed on both sides. The inner diameter of the circular groove 162 is larger than the groove width of the rectangular groove 161.

[0049] Telescopic rod 25, one end of which is fixedly mounted on rectangular groove 161, and the other end is fixedly connected to the bottom of connector 24.

[0050] In this embodiment of the invention, this design facilitates the positioning structure to fix the position of the adjustment structure, thereby making it easier to fix the position of the recycling structure.

[0051] like Figure 1 As shown, in a preferred embodiment of this utility model, the support structure includes:

[0052] Base 11;

[0053] A base plate 14, on which a sliding sleeve 16 is slidably connected, and a water tank filled with water is placed on the base plate 14;

[0055] A connecting plate 15 is fixedly connected to a base 11 on one side and to a limiting plate 17 on the other side.

[0056] In this embodiment of the utility model, two limiting plates 17 are used to limit the sliding sleeve 16 to prevent the sliding sleeve 16 from falling off the base plate 14 when adjusting the distance between the two heating plates 21.

[0057] like Figure 1-3 As shown, in a preferred embodiment of this utility model, the control component includes:

[0058] The support plate 12 is fixedly mounted on the base 11;

[0059] Turntable 19, wherein a groove 29 is provided in the turntable 19, and the groove 29 is shaped like an "8";

[0060] A connecting rod 32 is rotatably connected to a support plate 12. One end of the connecting rod 32 is fixedly connected to a turntable 19. The outer wall of the connecting rod 32 is provided with an external thread. A fastening nut 33 is threaded onto the external thread.

[0061] The control panel 13 is fixedly mounted on the other end of the connecting rod 32;

[0062] A guide seat 28 is fixedly mounted on a base 11. A guide groove 31 is provided in the guide seat 28. Two symmetrically arranged sliding heads 27 are slidably connected in the guide groove 31. The two sliding heads 27 are fixedly connected to two clamping plates 26 respectively, and the ends of the two sliding heads 27 are slidably connected to the sliding groove 29.

[0063] In this embodiment of the invention, when using the device, a water tank filled with water is placed on the base plate 14. The heating plate 21 is adjusted to a suitable height using the telescopic rod 25, and the sliding sleeve 16 is controlled to move relative to the base plate 14, so that the two heating plates 21 move closer to each other and fit against the sides of the water tank. The operation of fixing the position of the heating plate 21 is as follows:

[0064] First, fix one side by unscrewing the fastening nut 33 away from the support plate 12. Then, rotate the control disk 13. The control disk 13 drives the turntable 19 to rotate via the connecting rod 32. The turntable 19 drives the slide groove 29 to rotate. Guided by the guide groove 31, the slide groove 29 drives the two sliding heads 27 to move closer together through a sliding connection with them. This causes the two clamping plates 26 to move closer together until the inner sidewalls of the two clamping plates 26 abut against the circular groove 162 at one end of the two sliding sleeves 16. At this point, screw in the fastening nut 33 until it abuts against the sidewall of the support plate 12, completing the fixation of one side. The operation on the other side is the same, thus completing the fixation of the heating plate 21.

[0065] The working principle of this utility model is as follows:

[0066] In operation, the waste heat recovery device for this fuel cell is used by placing a water tank filled with water on the base plate 14. The heating plate 21 is adjusted to a suitable height using the telescopic rod 25, and the sliding sleeve 16 is moved relative to the base plate 14, causing the two heating plates 21 to move closer together and contact the sides of the water tank. Then, one side of the two adjustment structures is fixed by unscrewing the fastening nut 33 away from the support plate 12. Next, the control disk 13 is rotated, which drives the turntable 19 to rotate via the connecting rod 32. The turntable 19, through a sliding groove 29, slides the two sliding heads 27 closer together, causing the two clamping plates 26 to move closer together and abut against the circular groove 162 at one end of the two sliding sleeves 16. At this point, the fastening nut 33 is screwed in until it abuts against the side wall of the support plate 12, completing the fixing of one side. The operation on the other side is the same, thus fixing the position of the heating plate 21. At this time, hot steam is delivered to the inside of the delivery pipe 23 and then to the inside of the connecting seat 22, and finally reaches the inside of the heating plate 21 to heat the heating plate 21. The high temperature of the heating plate 21 can then heat the water inside the water tank.

[0067] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
