Then, the water inside the water tank 7 is pumped out by starting the water pump 11, and then transported to the circulating water pipe 13 through the connecting pipe 12. The connecting pipe 12 connects the water pump 11 and the circulating water pipe 13 to ensure that the water can be smoothly transmitted from the water pump 11 to the circulating water pipe 13. During the process of water flowing in the waste heat collection box 6, it can fully contact the heat inside the waste heat collection box 6, efficiently absorb heat, and finally be transported back to the water tank 7 through the delivery pipe 14. The delivery pipe 14 serves as a return water channel to transport the water that has absorbed heat back to the water tank 7, so that the temperature inside the water tank 7 gradually increases. When the water temperature in the water tank 7 reaches a certain level, the user can obtain hot water through the water outlet pipe 2 9 to meet the needs of daily life or production. At the same time, the valve 10 set on the side wall of the water outlet pipe 2 9 can control the flow and on-off of the water, so that the user can adjust it according to actual needs.

[0035] Reference Figure 1 and Figure 4 The sealing assembly includes a cover plate 18, which can fit tightly against the inner wall of the waste heat collection box 6 to seal the waste heat collection box 6. A sealing sleeve 19 is fixedly connected to the lower surface of the cover plate 18, which further enhances the sealing performance. The side wall of the waste heat collection box 6 is fixedly connected to a mounting plate 20, and the side wall of the mounting plate 20 is fixedly connected to a fixing plate 1 21. The fixing plate 1 21 provides support and a rotation connection point for the triangular rotating block 22. A connecting rod 1 23 is fixedly connected between the triangular rotating blocks 22. The connecting rod 1 23 serves to connect the two triangular rotating blocks 22. A sliding block 25 is slidably connected to the inside of the mounting plate 20. The sliding block 25 can slide in the mounting plate 20. A fixed column 24 is fixedly connected to the side wall of the sliding block 25. The fixed column 24 provides a fulcrum for the connection between the sliding block 25 and the triangular rotating block 22, so that the sliding of the sliding block 25 can drive the triangular rotating block 22 to rotate. The upper surface of the mounting plate 20 is fixedly connected with a fixing plate 26, and the internal thread of the fixing plate 26 is connected with a screw 27, which can push the sliding block 25 to slide by rotation. The side wall of the screw 27 is rotatably connected to the inside of the sliding block 25, and the side wall of the mounting plate 20 is rotatably connected with a fixing plate 3 28, and the fixing plate 3 28 provides an installation basis for the pressure plate 31. The fixing plates 3 28 are fixedly connected with a connecting rod 2 30, and the connecting rod 2 30 enhances the stability of the fixing plate 3 28. The side wall of the connecting rod 2 30 is rotatably connected with a rotating plate 29, and the side wall of the fixing plate 3 28 is fixedly connected with a pressure plate 31, and the lower surface of the pressure plate 31 fits the upper surface of the cover plate 18. By pressing the cover plate 18 down, the sealing effect is further enhanced to ensure the sealing of the waste heat collection box 6.

[0036] Before the device is operated, the waste heat collection box 6 is covered with the cover plate 18. The cover plate 18 seals the waste heat collection box 6, preventing heat loss from the waste heat collection box 6. It also prevents external impurities from entering the waste heat collection box 6 and affecting the waste heat collection effect. The sealing sleeve 19 can tightly fit the inner wall of the waste heat collection box 6, forming a good sealing effect, further reducing heat loss and improving thermal insulation performance. Then, by rotating the screw 27, the screw 27 acts as an adjustment device. The rotation of the screw 27 can generate axial thrust, causing it to push the sliding block 25 to slide. Under the push of the screw 27, the sliding block 25 can slide smoothly along a specific track, thereby converting the rotational motion of the screw 27 into linear motion. The sliding of the sliding block 25 allows the triangular rotating block 22 to rotate. The triangular rotating block 22 rotates under the action of the sliding block 25. The rotation of the fixed plate three 28 can change its angle and position, preparing for the compression of the cover plate 18, and then the pressing plate 31 is pressed down. The pressing plate 31 is pressed downward under the action of the fixed plate three 28, applying pressure to the cover plate 18, and further compressing the cover plate 18. The pressing action of the pressing plate 31 can ensure that the sealing between the cover plate 18 and the waste heat collection box 6 is more reliable, thereby improving the sealing effect, minimizing heat loss, and improving the efficiency of waste heat collection and utilization.

[0037] Working principle: When the equipment is in use, the waste heat generated by the ground source heat pump during operation will be transported into the waste heat collection box 6 through the exhaust pipe 4, so that the waste heat generated is concentrated together, and the waste heat collection box 6 is filled with heat. Then, the water in the water tank 7 is pumped out by starting the water pump 11, and then transported to the circulating water pipe 13 through the connecting pipe 12, so that the water flow absorbs the heat inside the waste heat collection box 6, and finally transported back to the water tank 7 through the delivery pipe 14. This cycle is repeated, so that the temperature inside the water tank 7 gradually increases, and hot water is provided to the user through the outlet pipe 2 9. Before the equipment works, the waste heat collection box 6 is covered by the cover plate 18, so that the sealing sleeve 19 fits the inside of the waste heat collection box 6 to seal and insulate it. Then, by rotating the screw 27, it pushes the sliding block 25 to slide. The sliding of the sliding block 25 causes the triangular rotating block 22 to rotate, and the rotating plate 29 pushes the fixed plate 3 28 to rotate, and then the pressure plate 31 is pressed down, further pressing the cover plate 18, thereby improving the sealing effect.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
