Description

Technical Field

[0001] This invention belongs to the technical field of mobile heating equipment, specifically relating to a heat storage vehicle and its operation method for preventing heat loss during transportation. Background Technology

[0002] Thermal energy storage vehicles are a type of special vehicle primarily used for storing and transporting thermal energy. They can store thermal energy inside and transport it to residential areas in need for utilization.

[0003] In rural areas, photovoltaic panels are often installed on rooftops of houses, and wind turbines are set up in fields to generate electricity. However, current methods for processing this electricity are limited, allowing only temporary storage until needed later. Long-distance transmission inevitably results in some losses. Solid-state energy storage devices use electric heating wires to heat magnesium bricks, converting off-peak electricity into heat for storage. Rural-generated natural electricity is inexpensive; if this electricity is used to store heat and then supplied to residents around cities via heat storage vehicles, it can significantly reduce costs and directly increase farmers' income.

[0004] Current thermal storage vehicles have many shortcomings. The thermal storage tanks and vehicles are often connected together, or external lifting equipment is required for loading and unloading the tanks, making the process extremely inconvenient. Some even require parking in residential areas and waiting until the heat source conversion is complete before leaving. Furthermore, heat loss is common during the transportation of heat sources using these vehicles, and the longer the transportation distance, the greater the heat loss. This significantly reduces the profitability of farmers selling electricity converted into heat.

[0005] Therefore, the present invention provides a heat storage vehicle to prevent heat loss during transportation, thereby solving the above-mentioned problems. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a thermal energy storage vehicle to prevent heat loss during transportation, so as to solve the problems of inconvenience in loading and unloading thermal energy storage boxes of different energy storage types and serious heat loss during long-distance transportation.

[0007] To achieve the above objectives, in a first aspect, the present invention provides a thermal storage vehicle for preventing heat loss during transport, comprising a thermal storage vehicle body and a thermal storage box. The thermal storage box contains a thermal storage chamber and a heat exchange chamber, with the thermal storage chamber supplying heat to the heat exchange chamber via airflow. Magnesium bricks and heating wires are disposed within the thermal storage chamber. A photovoltaic power generation module is disposed on the top of the thermal storage box, with its power output terminal connected to the heating wires. A support plate is mounted at the rear of the thermal storage vehicle body, and the thermal storage box is mounted on the support plate. A vertical positioning plate is disposed on the support plate, with a dragging mechanism on the front side of the vertical positioning plate and a box unloading mechanism below the thermal storage box. A locking mechanism and a trigger-stop mechanism are disposed on the vertical positioning plate; the locking mechanism prevents the thermal storage box from moving forward or backward, and the trigger-stop mechanism prevents excessive dragging of the thermal storage box. A rear baffle is disposed at the rear end of the support plate, and guide rails are disposed on both the support plate and the rear baffle. Two sets of rollers are disposed on the bottom surface of the thermal storage box. The rear baffle is connected to a flipping mechanism and a lifting mechanism.

[0008] Preferably, the positioning mechanism includes a mounting groove, which is located on the rear side of the vertical positioning plate. The mounting groove has an inner slot, which is used to embed the insert block. The insert block is fixedly connected to the heat storage box. The end of the insert block has an arc-shaped surface, and the insert block can slide into the inner slot.

[0009] Preferably, a limiting mechanism is provided in the mounting slot to prevent relative movement between the mounting slot and the insert block; the limiting mechanism adopts a manual pin, an automatic pin structure, or a coupler structure.

[0010] Preferably, two sets of side guards are installed on the load-bearing vehicle plate, and each side guard has a set of ball bearings installed inside.

[0011] Preferably, the unloading mechanism adopts an electric push rod mechanism, a motor-driven gear and rack structure, or a screw mechanism.

[0012] Preferably, the thermal storage chamber is equipped with a one-way valve at both the inlet and outlet ends, an exhaust duct at the outlet end, and a collecting duct at the inlet end. The inlet of the collecting duct and the outlet of the exhaust duct both face the outside of the thermal storage chamber, and a fan is installed at the inlet of the collecting duct at the inlet end.

[0013] Preferably, a set of heat exchange copper tubes is installed in the heat exchange chamber, with the two ends of the heat exchange copper tubes connected to the water inlet and the water outlet respectively, and the outer wall of the heat exchange copper tubes is provided with reinforced heat exchange fins.

[0014] Preferably, the top of the thermal storage box is also equipped with a wind-driven power generation mechanism, and the power output end of the wind-driven power generation mechanism is connected to the heating wire.

[0015] Preferably, the triggering and stopping mechanism includes a clamping block and a mating groove. The mating groove is formed on the insert block, and a push-button breaker is installed inside the mounting groove. One end of the clamping block is fixedly connected to a connecting rod, and the other end is equipped with a push-button breaker. The two ends of the connecting rod are respectively connected to the clamping block and a back plate, and the connecting rod and the back plate can extend into the mating groove. A second spring is provided on the outside of the connecting rod, and the two ends of the second spring are respectively fixedly connected to the inner side wall of the mating groove and the back plate. The clamping block can abut against and trigger the push-button breaker.

[0016] Secondly, the present invention also provides an operating method for the thermal storage vehicle that prevents heat loss during transportation. In areas with surplus wind power and / or solar photovoltaic power generation, the power output terminal of the wind power and / or solar photovoltaic power generation system is connected to a heating wire. The heating wire heats the magnesium bricks, converting electrical energy into thermal energy for storage. After thermal storage is completed, the vehicle is driven to the area requiring heating, and the thermal storage chamber is opened to supply heat to the heat exchange chamber, which then supplies heat to the outside. When loading the thermal storage box, a towing mechanism is used to assist loading, and when unloading the thermal storage box, an unloading mechanism is used to assist unloading. A positioning mechanism is used to prevent the thermal storage box from moving forward and backward, and a trigger stopping mechanism is used to prevent excessive dragging of the thermal storage box.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention, through the cooperation between the towing hook, the towing mechanism, the rear baffle, the lifting mechanism and the unloading mechanism, can conveniently and quickly load and unload the thermal storage box, thereby enabling the thermal storage box to be unloaded after the actual heating is completed and then recycled; at the same time, the photovoltaic power generation module is set to supplement the heat of the thermal storage box, reducing the heat loss during transportation.

[0018] Furthermore, by using the cooperation between the insert block, the mounting slot, the limiting mechanism, and the limiting release mechanism, the present invention can quickly connect the thermal storage box to the vertical positioning plate, thereby enabling convenient and quick positioning of different types of thermal storage boxes. By using the cooperation between the limiting mechanism and the limiting release mechanism, the insert block can be easily removed, making it easy to disconnect the connection to the thermal storage box, thus enabling different types of thermal storage boxes to be carried on the support vehicle plate.

[0019] Furthermore, by using a wind-driven power generation mechanism, the present invention can generate electricity during the movement of the thermal storage vehicle, power the heating wires, and use wind energy to convert into electrical energy and then into heat energy to keep the heat stored in the magnesium bricks warm, thereby further offsetting the heat loss during transportation.

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] refer to Figures 1 to 11 This invention provides a thermal energy storage vehicle for preventing heat loss during transportation, comprising a thermal energy storage vehicle body 1 and a thermal energy storage box 3. A load-bearing vehicle plate 2 is installed at the rear of the thermal energy storage vehicle body 1, and a vertical positioning plate 5 is installed on the load-bearing vehicle plate 2. Two reinforcing plates 6 are fixedly connected to the side of the vertical positioning plate 5 near the front of the vehicle. The bottom surfaces of the two reinforcing plates 6 are connected to the load-bearing vehicle plate 2. By setting two reinforcing plates 6, the vertical positioning plate 5 can be reinforced. The reinforcing plates 6 are welded to the vertical positioning plate 5, and both the vertical positioning plate 5 and the reinforcing plates 6 are welded to the load-bearing vehicle plate 2.

[0036] refer to Figure 3 , Figure 4 , Figure 11A towing hook 4 is fixedly connected to the front of the heat storage box 3, and a towing mechanism 8 is provided in front of the vertical positioning plate 5. The vertical positioning plate 5 has a through hole 7. The towing mechanism 8 includes an electric winding roller 801, which is mounted on the carrier plate 2. A winding rope 802 is wound around the outer surface of the electric winding roller 801. The winding rope 802 passes through the through hole 7 and extends to the rear of the vertical positioning plate 5. A pull hook 803 is fixedly connected to the free end of the winding rope 802. The pull hook 803 is hooked to the towing hook 4. By using the electric winding roller 801, the winding rope 802 can be wound or unwound, so that the pull hook 803 can drag the towing hook 4, thereby dragging the heat storage box 3 onto the carrier plate 2.

[0037] refer to Figure 2 , Figure 5 The rear side of the vertical positioning plate 5 is equipped with an installation groove 10. The installation groove 10 has an inner groove 11. The installation groove 10 is used to embed the plug 9. The plug 9 is fixedly connected to the heat storage box 3. The end of the plug 9 is provided with an arc surface 12. The plug 9 can slide into the inner groove 11. The internal size of the inner groove 11 is adapted to the plug 9, so that the plug 9 can be easily inserted into the inner groove 11.

[0038] The automatic latch structure can be referenced. Figure 6 and Figure 7 The mounting groove 10 is internally equipped with a limiting mechanism 14, which includes an iron block 1401 and a limiting arc panel 1403. The limiting arc panel 1403 is disposed within the mounting groove 10 and can reciprocate along its own axial direction. One end of the insert block 9 is externally limited by a groove 13, and the limiting arc panel 1403 can extend into the external limiting groove 13. The end of the limiting arc panel 1403 extending into the external limiting groove 13 is provided with an arc-shaped surface, which facilitates the insertion of the insert block 9. The arc-shaped surface 12 pushes the limiting arc panel 1403 to move, avoiding interference between the limiting arc panel 1403 and the insertion of the insert 9 when the heat storage box 3 is dragged above the support plate 2; when the insert 9 enters the inner slot 11, the arc-shaped surface 12 first contacts the arc-shaped surface on the limiting arc panel 1403, the insert 9 presses against the limiting arc panel 1403, and when the insert 9 is fully embedded in the inner slot 11, the limiting arc panel 1403 pops out and enters the outer limiting slot 13 on the insert 9. One end of the pull rod 1402 is fixedly connected to the connecting end of the limiting arc panel 1403. The pull rod 1402 slides through the mounting slot 10, and the other end of the pull rod 1402 is fixedly connected to the iron block 1401. A first spring 1404 is provided on the outside of the pull rod 1402. The two ends of the first spring 1404 are fixedly connected to the limiting arc panel 1403 and the inner wall of the mounting slot 10, respectively. Figure 7 In the state shown, it is neither compressed nor stretched. Using the elastic force of the first spring 1404, it can drive the limiting arc panel 1403, which was pushed open by the arc surface 12, to return to its original position, so that it can automatically insert into the interior of the outer limiting groove 13 to limit the insertion block 9.

[0039] As a possible optimization, the curved surface 12 or the curved surface of the limiting curved panel 1403 can be embedded with balls or rollers to reduce the friction after the two come into contact, making it easier for the insert 9 to be embedded into the inner slot 11.

[0040] refer to Figure 6 and Figure 7 The mounting slot 10 is provided with a limit release mechanism 15. The limit release mechanism 15 includes an electromagnet 1503 and a frame plate 1504. The frame plate 1504 is fixedly connected to the mounting slot 10. A power supply 1501 is installed on the frame plate 1504. A wire 1502 is fixedly connected to the power supply end of the power supply 1501. One end of the wire 1502 is fixedly connected to the electromagnet 1503. By starting the power supply 1501, the wire 1502 can supply power to the electromagnet 1503, so that the electromagnet 1503 can attract the iron block 1401 to move. The iron block drives the pull rod 1402 and the limit arc panel 1403 to move outward from the mounting slot 10, so that the limit arc panel 1403 can contact the limit of the external limit slot 13, which makes it convenient to remove the heat storage box 3 from the carrier plate 2.

[0041] refer to Figure 8 The insert 9 has a trigger stop mechanism 16 installed inside. The trigger stop mechanism 16 includes a clamping block 1604 and a mating groove 1601. The mating groove 1601 is formed on the insert 9. A push-button breaker 17 is installed inside the mounting groove 10. One end of the clamping block 1604 is fixedly connected to a connecting rod 1602, and the other end is provided with the push-button breaker 17. The two ends of the connecting rod 1602 are respectively connected to the clamping block 1604 and the back plate 1603. The back plate 1603 can extend into the mating groove 1601. A second spring 1605 is provided on the outer side of the connecting rod 1602. The two ends of the second spring 1605 are fixedly connected to the inner side wall of the mating groove 1601 and the back plate 1603, respectively. The pressing block 1604 can abut against the press-type circuit breaker 17. After the press-type circuit breaker 17 transmits a signal, it can stop the electric winding roller 801. When dragging the heat storage box 3 to the top of the carrier plate 2, it can prevent the electric winding roller 801 from continuously winding and damaging the connecting parts.

[0042] The connecting rod 1602 and the back plate 1603 can slide inside the mating groove 1601, which can prevent the pressing block 1604 from continuously pressing against the push-type circuit breaker 17, which would damage the push-type circuit breaker 17. The overall function of the trigger stop mechanism 16 is to provide a buffering effect when the push-type circuit breaker 17 is triggered.

[0043] refer to Figure 1 and Figure 2Two sets of side guards 18 are installed on the load-bearing vehicle plate 2. Each side guard 18 has a set of rolling balls 19 installed inside. By using the side guards 18, the side of the heat storage box 3 can be protected. By using the multiple rolling balls 19, the friction between the side guards 18 and the side of the heat storage box 3 can be reduced when dragging or unloading the heat storage box 3.

[0044] The rear end of the support plate 2 is provided with a rear baffle 22, the top of the support plate 2 is provided with an unloading mechanism 26, the upper surface of the support plate 2 is provided with two long guide rails 20, and the bottom of the heat storage box 3 is provided with two sets of moving wheels 25, each moving wheel 25 is in contact with the long guide rail 20. The rear baffle 22 is connected to the support plate 2 by a connecting hinge 21. When the rear baffle 22 is in a vertical state, the vertical direction of the rear baffle 22 can be limited by a limiting member, which can prevent the heat storage box 3 from falling from the rear end of the support plate 2.

[0045] refer to Figure 2 and Figure 9 Two short guide rails 23 are provided on the upper part of the rear baffle 22. By using the long guide rail 20 and the short guide rail 23, the moving wheels 25 under the heat storage box 3 can be guided during the movement of the heat storage box 3, so as to avoid the heat storage box 3 from deviating when it moves on the support plate 2 and the rear baffle 22. Two lifting mechanisms 24 are provided under the support plate 2. The lifting mechanism 24 includes a first mounting base 2403, which is fixedly connected to the support plate 2. A first electric push rod 2401 is installed inside the first mounting base 2403. The output end of the first electric push rod 2401 is connected to the lifting plate 2402. By using the first electric push rod 2401, the lifting plate 2402 can be extended so that the lifting plate 2402 can press against the rear baffle 22. After the lifting plate 2402 is retracted, it does not affect other structures and is more aesthetically pleasing.

[0046] refer to Figure 2 and Figure 10 The unloading mechanism 26 adopts an electric push rod mechanism, specifically including a second mounting base 2603. The second mounting base 2603 is installed on the upper surface of the carrier plate 2. A second electric push rod 2601 is installed inside the second mounting base 2603. The output end of the second electric push rod 2601 is fixedly connected to a pull unloading plate 2602. The right side of the pull unloading plate 2602 contacts the left side of the heat storage box 3.

[0047] As an optional embodiment, the unloading mechanism 26 can adopt a motor-driven gear and rack structure, with a rack at the bottom of the heat storage box 3 and a motor on the supporting vehicle plate 2. The output end of the motor is connected to a reduction gear assembly, and the output gear of the reduction gear assembly meshes with the rack. When the motor is turned on, the heat storage box 3 can be smoothly pushed to the rear of the vehicle.

[0048] The unloading mechanism 26 can also be a screw mechanism. The screw is fixed on the bearing plate 2, the screw nut is connected to the bottom of the heat storage box 3, and one end of the screw is connected to the motor output.

[0049] Working principle:

[0050] When heating and energy storage are required, the heat storage box 3 is first removed, the limiting member of the rear baffle 22 is released, and the rear baffle 22 is flipped over. The first electric push rod 2401 is activated, which can drive the lifting plate 2402 to move, so that the lifting plate 2402 can press against the rear baffle 22. By activating the power supply 1501, the electromagnet 1503 can be powered by the wire 1502, so that the electromagnet 1503 attracts the iron block 1401 to move. The iron block 1401 can drive the pull rod 1402 and the limiting arc panel 1403 to release the limitation of the external limiting groove 13 and the insert block 9. By activating the second electric push rod 2601, the unloading plate 2602 can be driven to pull the thermal storage box 3. The moving wheels 25 at the bottom of the thermal storage box 3 will move under the guidance of the long guide rail 20 and the short guide rail 23, thus unloading the thermal storage box 3. By connecting the electrical energy generated by the solar panel or wind power generation mechanism to the heating wire 35, power can be supplied to the heating wire 35. After the heating wire 35 heats up, it can heat the magnesium brick 34 and store energy. (Reference) Figure 12 .

[0051] When the heat storage box 3 is dragged to the top of the carrier plate 2 after the heat storage is completed, the electric winding roller 801 is activated to wind up the winding rope 802, which enables the pulling hook 803 and the drag hook 4 to be dragged. After the heat storage box 3 is moved to the top of the carrier plate 2, the insert 9 will be inserted into the inner slot 11 opened inside the mounting groove 10. The arc surface 12 will push open the limiting arc panel 1403 until the insert 9 is fully inserted into the inner slot 11. Under the elastic force of the first spring 1404, the limiting arc panel 1403 can be driven to limit the outer limiting groove 13, which can automatically lock the insert 9, thereby realizing the automatic connection and unloading of the heat storage box 3, and making it convenient to replace different types of heat storage boxes 3.

[0052] During the process of dragging the heat storage box 3 onto the carrier plate 2, the clamping block 1604 will press against the push-type circuit breaker 17. After the plug 9 and the mounting slot 10 are connected, the clamping block 1604 will trigger the push-type circuit breaker 17 to cut off the power to the electric winding roller 801, so as to prevent the electric winding roller 801 from continuously pulling on the heat storage box 3 and causing damage to the connecting parts. The heat storage box 3 is transported to the urban heating community using the heat storage vehicle body 1. The heat storage box 3 is then lowered again, so that it can be used by the urban community residents.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that the wind-driven power generation mechanism 27 can continuously heat the magnesium bricks 34 during the movement of the heat storage vehicle body 1, which can prevent heat loss and increase the total amount of heat energy stored.

[0055] like Figure 1 , Figure 11 , Figure 12 and Figure 13 As shown, a wind-driven power generation mechanism 27 is installed above the thermal storage box 3. The wind-driven power generation mechanism 27 includes wind-driven blades 2702 and a generator 2704. A thermal storage chamber 31 is installed inside the thermal storage box 3. A set of magnesium bricks 34 and heating wires 35 are installed inside the thermal storage chamber 31. A long heating wire 35 is inserted between each horizontal set of magnesium bricks 34. All the heating wires 35 are connected together and can be heated by a single power source.

[0056] The windward power generation mechanism 27 also includes a housing 2701, windward blades 2702 are installed on the inner wall of the housing 2701, a gearbox 2703 and a generator 2704 are installed inside the windward blades 2702, a connecting column 2705 is fixedly connected to the bottom surface of the housing 2701, a connecting wire 2706 is installed inside the connecting column 2705, a base plate 2707 is fixedly connected to the connecting column 2705, and the base plate 2707 is fixedly connected to the heat storage box 3. Using the windward power generation mechanism 27, it is possible to generate electricity and supply power to the heating wire 35 when the heat storage vehicle body 1 is moving, thereby increasing the total amount of heat energy inside the heating wire 35.

[0057] A set of ventilation holes 28 is provided at the rear end of the heat storage box 3. A mounting frame 29 is installed on the rear wall of the heat storage box 3. A fan 30 is installed on the inner wall of the mounting frame 29. A first one-way valve 32 is installed on the rear side wall of the heat storage chamber 31. The air inlet of the first one-way valve 32 is fixedly connected to an air collecting hopper 33. The air collecting hopper 33 can guide the air generated by the fan 30 into the interior of the first one-way valve 32 to a large extent. A second one-way valve 36 is installed on the front side wall of the heat storage chamber 31. The air outlet of the second one-way valve 36 is fixedly connected to an exhaust hopper 37. Both the first one-way valve 32 and the second one-way valve 36 can only supply air in one direction to avoid backflow of gas and damage to the fan 30.

[0058] The inner wall of the heat storage box 3 is equipped with a heat exchange chamber 38, and a set of heat exchange copper tubes 39 are installed inside the heat exchange chamber 38. The exhaust fan 37 is used to allow hot air to blow more comprehensively onto the heat exchange copper tubes 39. The water inlet end of the heat exchange copper tubes 39 is fixedly connected to a water inlet interface 40, and the water outlet end of the heat exchange copper tubes 39 is fixedly connected to a water outlet interface 41. When supplying water into the water inlet interface 40, an external water pump should be used.

[0059] Working principle: During the movement of the thermal storage vehicle body 1, the wind vane 2702 will rotate. After the gearbox 2703 changes speed, the generator 2704 can generate electricity. The electrical energy generated by the generator 2704 can supply power to the heating wire 35 through the connecting wire 2706, thereby heating the magnesium brick 34. This can offset the heat loss during transportation and increase the total amount of thermal energy stored in the magnesium brick 34 during transportation.

[0060] By connecting an external water source to the inlet port 40 and the water pipe to the outlet port 41, and by starting the fan 30, the user can blow air into the air collection hopper 33. The cold air is sent into the heat storage chamber 31 through the first one-way valve 32, carrying away the heat from the magnesium bricks 34. The air is then sent into the heat exchange chamber 38 through the second one-way valve 36 and the exhaust hopper 37, thereby heating the cold water flowing into the heat exchange copper tube 39.
