Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange devices for rural houses, in particular to a heat exchange device for rural houses. Background Technique

[0002] Under the premise of advocating a low-carbon and environment-friendly lifestyle today, a winter heating coal replacement project has been implemented in the vast rural areas of northern China, using current environment-friendly natural gas, electricity, air source heat pumps, etc. as the heat sources for winter indoor heating.

[0003] However, due to the general lack of heat-insulating outer walls in rural houses, large areas, and scattered distribution, centralized heating cannot be carried out, resulting in too high costs after using natural gas, electricity, air source heat pumps, etc. for winter indoor heating, which to a certain extent reduces the happiness of rural residents. On the other hand, solar energy is relatively abundant in winter in the vast areas of northern China, but it has not been used as a heat source for heating in the vast rural areas. Therefore, it is necessary to design a heat exchange device for rural houses that can utilize solar energy.

[0004] It should be noted that the above content belongs to the technical cognition scope of the utility model person and does not necessarily constitute the prior art. Content of the Utility Model

[0005] Based on this, in view of the above technical problems, it is necessary to provide a heat exchange device for rural houses.

[0006] In order to achieve the above object, the utility model provides a heat exchange device for rural houses, including:

[0007] A housing body, including an original heat source, a water inlet pipe, a water outlet pipe, and heat dissipation fins;

[0008] A solar energy collection mechanism, including a solar photovoltaic frame, a solar heat collection frame, a storage battery, a heat preservation barrel, a first water pump valve group, a second water pump valve group, a valve group, an input pipe, and an output pipe. The solar photovoltaic frame and the solar heat collection frame are both installed on the housing body, the storage battery and the heat preservation barrel are both installed inside the housing body. The solar heat collection frame is communicated with the water inlet pipe and the water outlet pipe through the input pipe and the output pipe respectively. The first water pump valve group is installed on the input pipe. The heat preservation barrel is communicated with the input pipe and the output pipe through the second water pump valve group and the valve group respectively. The input end of the storage battery is electrically connected to the solar photovoltaic frame, and the output end of the storage battery is electrically connected to the first water pump valve group and the second water pump valve group;

[0009] Adjusting mechanism, comprising a heat collecting plate group, light-transmitting holes, abutting frames, limiting frames, movable heat collecting plates, connecting blocks, movable photovoltaic panels, card slots, threaded rods, pushing blocks, sliding grooves and sliding plates. The heat collecting plate group is installed on a solar heat collecting rack, and a number of groups of light-transmitting holes are provided on the solar heat collecting rack. The light-transmitting holes and the heat collecting plate group are arranged at intervals. A number of groups of abutting frames and limiting frames are installed at the bottom of the solar heat collecting rack. A movable heat collecting plate is slidably clamped in the limiting frame. The movable heat collecting plate is connected to the movable photovoltaic panel through a connecting block. A card slot is provided on the connecting block, and the card slot penetrates through the limiting frame. A threaded rod is rotatably installed on the abutting frame, and a number of pushing blocks are threadedly connected to the threaded rod. The pushing blocks are arranged in cooperation with the card slot. A sliding groove is provided on the limiting frame, and a sliding plate is slidably installed in the sliding groove and can slide along the length direction of the sliding groove;

[0010] Driving mechanism, used to drive the threaded rod to rotate.

[0011] By adopting the above technical solution, when the original heating source of the house body heats the water source, the water source is heated by the original heat source, and then the water source is driven to flow to the radiator through the water inlet pipe for heat dissipation. After that, the low-temperature water source is recycled to the original heat source through the water outlet pipe. Now, through the solar energy collection mechanism, in sunny winter days in the north, solar energy can be used to heat a number of heat collection panel groups and movable heat collection panels on the solar heat collection rack. The hot water heated by solar energy enters the radiator of the original heating system through the input pipe and the water inlet pipe. After the hot water dissipates heat indoors, it flows back to the solar heat collection rack through the water outlet pipe and the output pipe for reheating. The circulation of the hot water is driven by opening the valve of the water pump valve group 1 to start the water pump. The power supply comes from the storage battery, and the electrical energy of the storage battery is provided by a number of photovoltaic panels on the solar photovoltaic rack. If the indoor temperature reaches the heating requirement, the valve in the water pump valve group 1 is closed, and the water pump in the water pump valve group 2 is used to transport the excess hot water to the heat storage bucket for energy storage. At the same time, the valve group is opened so that the original air or low-temperature water source in the heat storage bucket can be transported out. The volume of the heat storage bucket can be determined according to the solar heat collection rack and the total heating area of the house. Then, when the water source in the heat storage bucket is transported outwards, the valve in the water pump valve group 2 is opened, and the water pump in the water pump valve group 1 is used to output the water. Preferably, when the roof area of the rural house is large enough and the area of the installed roof solar energy collection mechanism is also large enough (more than m²), the system can meet the indoor day and night heating in sunny days. If in adverse situations, such as extremely cold weather, cloudy days or insufficient sunlight, the original heat source can be used for supplementary heating or all heating, so that the solar energy resources can be maximally utilized and the heating cost of the original heating system can be reduced without demolishing the original heating system of the rural house. And when the weather is continuously sunny and there is no excessive heating demand, the range of the solar photovoltaic rack and the solar heat collection rack that can be irradiated by the sun can be adjusted through the adjustment mechanism, so as to avoid the waste of solar energy. During adjustment, the threaded rod is rotated by the driving mechanism, and the push block on the threaded rod abuts against the abutting frame and is driven to move downwards. When it moves to the card slot on the connecting block, the threaded rod starts to reverse, so that the push block can pass through the limiting frame and be stuck in the card slot on the connecting block. Then the threaded rod continues to reverse, so that the movable photovoltaic panel and the movable heat collection panel of the connecting block are driven to slide upwards by the push block, so that the original movable heat collection panel being irradiated by the light transmission hole is changed to the movable photovoltaic panel being irradiated, thus reducing the range of the heat generation irradiation and increasing the range of power generation.When the push block drives the connection block to move up and reset after moving up, the push block slides in the gap on the limit frame and is limited by it. When the connection block is driven to reset, the threaded rod rotates forward, so that the push block still limited by the limit frame can move down and get out of the slot, and then the push block and the abutment frame continue to move down a certain distance. After moving, the threaded rod reverses again, so that the push block can abut against the slide plate. After abutment, the push block can drive the slide plate to move up through friction. When the slide plate moves up, it can block the slot to allow the push block to pass smoothly. When the slide plate moves to the uppermost end of the slide slot and separates from the push block, it can slide along the slide slot to reset to the lowermost end, and the push block continues to abut against the limit frame and move up, and then abuts against the next slide plate and drives it to move up and repeat the above operation. Finally, several push blocks can push a specified number of connection blocks to move up and reset, such as only pushing several groups of connection blocks on the upper side, and not pushing those on the lower side, so that the adjustment of the solar irradiation area is more delicate. When not all the push blocks are working, the non-working push blocks will abut against the limit frame and be driven up a certain distance before the working push blocks can be stuck in the slots. However, when the threaded rod rotates forward to drive the push blocks downward, the non-working push blocks will first abut against the abutment frame and be driven down a certain distance before the working push blocks abut against the abutment frame. The upward and downward distances are balanced, so that the spacing between all the push blocks will not be affected. At the same time, when there are more sets of solar collector panels and light-transmitting holes, the abutment frame and the threaded rod can be extended to the solar photovoltaic frame for the push blocks to move.

[0012] Optionally, the mobile heat collecting panel and the mobile photovoltaic panel are both slidably connected to the limit frame through a card block, and a limit block is installed on the limit frame. The limit block is matched with the card block on the mobile photovoltaic panel, and the width of the card block is greater than the width of the card slot.

[0013] By adopting the above technical solution, a card block is also installed at the lower part of the mobile photovoltaic panel at the bottom, and is limited by its abutment with the limit frame. Except for the mobile photovoltaic panel at the bottom, the other mobile photovoltaic panels only have card blocks installed on the upper side. The card blocks abut and cooperate with the limit blocks, so that the mobile photovoltaic panels can be limited and clamped. The significance of this arrangement is that the limit blocks can be set higher, so that when the card blocks on the mobile solar collector panel on the lower side move up, they will not collide with the limit blocks.

[0014] Optionally, the driving mechanism includes a rotary driving device and a belt transmission assembly. The rotary driving device is installed on the solar collector frame. The output end of the rotary driving device is transmission-connected to one of the threaded rods. Adjacent threaded rods are transmission-connected via the belt transmission assembly.

[0015] By adopting the above technical solution, the threaded rod can be driven to rotate by the rotary drive device, and multiple threaded rods can be driven to rotate through the transmission of the belt drive assembly. The rotary drive device can be selected according to actual conditions, and the threaded rod can be driven by more than one rotary drive device.

[0016] Optionally, a stopper is installed on the slide plate, and a chamfer is provided on the slide plate.

[0017] By adopting the above technical solution, the chamfer set on the slide increases the contact area between the push block and the slide, so that the push block can drive the slide to move upward, and the stop block provides a guarantee for the push block to drive the slide to move upward, that is, the slide can be driven to move upward by the push block squeezing the stop block. Similarly, when the slide moves to the uppermost end of the slide groove, the threaded rod needs to drive the push block to rotate forward to a certain extent, so that the push block can move away from the slide, so that the push block no longer limits the stop block, and the slide, i.e., the stop block, can slide down and reset.

[0018] Optionally, a thermometer is installed in the room, and a liquid level meter and a water temperature meter are installed in the heat preservation barrel. The thermometer, the liquid level meter and the water temperature meter are all connected to the rotation drive device through a signal processor.

[0019] By adopting the above technical scheme, the thermometer, liquid level meter and water thermometer are all existing technologies. Through the setting of the thermometer, liquid level meter and water thermometer, the temperature inside the room, the temperature and water level in the insulation barrel can be detected, so as to intelligently control whether hot water enters the insulation barrel and whether the regulating mechanism is adjusted.

[0020] Optionally, the output end of the rotary drive device is transmission-connected to one of the threaded rods via a coupling.

[0021] By adopting the above technical solution, it is convenient for the rotary drive device to drive the threaded rod to rotate.

[0022] Optionally, the abutment frame is provided with a chamfer, and a plurality of universal beads are rotatably mounted on the abutment frame, and the universal beads are matched with the push block.

[0023] By adopting the above technical solution, when the push block moves downward, it can abut against the universal ball, thereby reducing the friction between the push block and the abutment frame.

[0024] This technical solution has at least the following beneficial effects:

[0025] By installing a relatively large - area solar photovoltaic rack and solar heat - collecting rack on the house body, it is possible to make full use of the vacant area on the roofs of rural houses in the north and the rich solar energy resources in winter without demolishing the original heating system of rural houses. The solar energy is maximally converted into indoor heating heat, reducing the heating costs using natural gas, electricity, air - source heat pumps, etc., improving the happiness of rural residents in the north during winter, and using heat - preservation barrels for energy storage to further improve the utilization rate of solar energy;

[0026] The push block is driven by a threaded rod to move, so as to drive the movable heat - collecting plate and the movable photovoltaic plate to move, and make the two move to the light - transmitting holes respectively for work. Thus, when the weather is sunny and there is no need to increase a large amount of heat energy, a relatively large - area heat - collecting plate can be replaced with a photovoltaic plate, thereby improving the utilization effect of solar energy;

[0027] 3. By using several push blocks to only push a specified number of connecting blocks for adjustment, such as only pushing several groups of connecting blocks on the upper side and not pushing those on the lower side, so that only a certain number of movable photovoltaic plates replace the movable heat - collecting plates, thus making the adjustment of the solar irradiation area more delicate and the utilization efficiency higher.

[0038] Please refer to Figures 1 to 8 , an embodiment of the present application provides a heat exchange device for rural houses, including:

[0039] The house body 1 includes an original heat source 11, a water inlet pipe 12, a water outlet pipe 13, and a radiator 14.

[0040] The solar energy collection mechanism 2 includes a solar photovoltaic frame 21, a solar heat collection frame 22, a storage battery 23, a heat preservation barrel 24, a first water pump valve group 25, a second water pump valve group 26, an input pipe 221 and an output pipe 222.

The storage battery 23 and the heat preservation barrel 24 are both installed inside the housing 1. The solar heat collection frame 22 is communicated with the water inlet pipe 12 and the water outlet pipe 13 through the input pipe 221 and the output pipe 222 respectively. The first water pump valve group 25 is installed on the input pipe 221. The heat preservation barrel 24 is communicated with the input pipe 221 and the output pipe 222 through the second water pump valve group 26 and the valve group 27 respectively. The input end of the storage battery 23 is electrically connected to the solar photovoltaic frame 21, and the output end of the storage battery 23 is electrically connected to the first water pump valve group 25 and the second water pump valve group 26. The first water pump valve group 25, the second water pump valve group 26 and the valve group 27 can all be water pumps and solenoid valves in the prior art;

[0041] The adjusting mechanism 3 includes a heat collection plate group 31, light-transmitting holes 32, abutting frames 33, limiting frames 34, a movable heat collection plate 35, a connecting block 36, a movable photovoltaic panel 37, a card slot 38, a threaded rod 39, a pushing block 301, a sliding groove 302 and a sliding plate 303. The heat collection plate group 31 is installed on the solar heat collection frame 22. A number of groups of light-transmitting holes 32 are provided on the solar heat collection frame 22. The light-transmitting holes 32 are arranged at intervals from the heat collection plate group 31. A number of groups of abutting frames 33 and limiting frames 34 are installed at the bottom of the solar heat collection frame 22. The movable heat collection plate 35 is slidably clamped in the limiting frame 34. The movable heat collection plate 35 is connected to the movable photovoltaic panel 37 through the connecting block 36. The card slot 38 is provided on the connecting block 36. The card slot 38 penetrates through the limiting frame 34. The threaded rod 39 is rotatably installed on the abutting frame 33. A number of pushing blocks 301 are threadedly connected to the threaded rod 39. The pushing blocks 301 are arranged in cooperation with the card slot 38. The sliding groove 302 is provided on the limiting frame 34. The sliding plate 303 is slidably installed in the sliding groove 302 and can slide along the length direction of the sliding groove 302. A certain distance can be left between the limiting frame 34 and the abutting frame 33 for installing a support frame;

[0042] The driving mechanism 4 is used to drive the threaded rod 39 to rotate. The water inlet end and the water outlet end of the movable heat collection plate 35 can be communicated with the input pipe 221 and the output pipe 222 by installing telescopic pipes. The telescopic pipes can be fixed on the adjacent abutting frames 33. The fixed heat collection plate group 31 is also communicated with the input pipe 221 and the output pipe 222. The movable photovoltaic panel 37 can realize its ability to generate electricity after moving to the light-transmitting holes 32 through the length of the extra wires. The output end of the storage battery 23 can also be connected to other electrical appliances in the housing 1.

[0043] When the original heating system of the housing body 1 was in operation, the original heat source 11 heated the water source. Then, the water source was driven through the inlet pipe 12 to the radiator 14 for heat dissipation. After that, the low-temperature water source was recycled back to the original heat source 11 through the outlet pipe 13. Now, through the solar energy collection mechanism 2, in the clear winter days in the north, solar energy can be used to heat a number of heat collection panel groups 33 and the movable heat collection panel 35 on the solar heat collection rack 22. The hot water heated by solar energy enters the radiator 14 of the original heating system through the input pipe 221 and the inlet pipe 12. After the hot water dissipates heat indoors, it flows back to the solar heat collection rack 22 through the outlet pipe 13 and the output pipe 222 for reheating. The circulation of the hot water is driven by opening the valve of the water pump valve group 1 25 to start the water pump. The power is supplied by the storage battery 23, and the electrical energy of the storage battery 23 is provided by a number of photovoltaic panels on the solar photovoltaic rack 21. If the indoor temperature reaches the heating requirement, the valve in the water pump valve group 1 25 is closed, and the water pump in the water pump valve group 2 26 transports the excess hot water to the heat storage bucket 24 for energy storage. At the same time, the valve group 27 is opened so that the original air or low-temperature water source in the heat storage bucket 24 can be transported out. The volume of the heat storage bucket 24 can be determined according to the solar heat collection rack 22 and the total heating area of the house. Then, when the water source in the heat storage bucket 24 is transported outwards, the valve in the water pump valve group 2 26 is opened, and the water pump in the water pump valve group 1 25 outputs the water. Preferably, in the case of rural houses with a large enough roof area and a large enough area of the roof-mounted solar energy collection mechanism 2 (exceeding 100 m²), the system can meet the indoor heating requirements day and night under sufficient sunlight. If in adverse situations, such as extremely cold weather, cloudy days, or insufficient sunlight, the original heat source 11 can be used for supplementary heating or full heating. Thus, without demolishing the original heating system of rural houses, the solar energy resources can be maximally utilized, and the heating cost of the original heating system can be reduced. And when the weather is continuously sunny and there is no excessive heating demand, the range that the solar photovoltaic rack 21 and the solar heat collection rack 22 can be irradiated by the sun can be adjusted through the adjustment mechanism 3 to avoid waste of solar energy. During adjustment, the driving mechanism 4 drives the threaded rod 39 to rotate. The push block 301 on the threaded rod 39 abuts against the abutting frame 33 and is driven to move downwards. When it moves to the card slot 38 on the connecting block 36, the threaded rod 39 starts to reverse. Thus, the push block 301 can pass through the limiting frame 34 and be stuck in the card slot 38 on the connecting block 36. Then, the threaded rod 39 continues to reverse, so that the movable photovoltaic panel 37 and the movable heat collection panel 35 of the connecting block 36 are driven to slide upwards by the push block 301, making the original movable heat collection panel 35 irradiated by the light-transmitting hole 32 be changed to the movable photovoltaic panel 37 being irradiated, thereby reducing the range irradiated by heat and increasing the range of power generation.When the push block 301 drives the connecting block 36 to move upward and reset after moving upward, the push block 301 slides in the gap on the limiting frame 34 and is limited by it. When the connecting block 36 is driven to reset, the threaded rod 39 rotates forward, so that the push block 301, which is still limited by the limiting frame 34, can move downward and disengage from the slot 38. Then the push block 301 and the abutment frame 33 continue to move downward for a certain distance. After moving, the threaded rod 39 reverses again, so that the push block 301 can The push block 301 abuts against the slide plate 303, and after the abutment, the slide plate 303 can be driven to move upward by friction. When the slide plate 303 moves upward, it can block the slot 38 to allow the push block 301 to pass smoothly. When the slide plate 303 moves to the uppermost end of the slide slot 302 and separates from the push block 301, it can slide along the slide slot 302 to reset to the lowermost end, and the push block 301 continues to abut against the limit frame 35 and move upward, and then abuts against the next slide plate 303 and drives it to move upward and repeat the above operation. Finally, several push blocks 301 can push a specified number of connection blocks 36 to move upward and reset, such as only pushing several groups of connection blocks 36 on the upper side, and not pushing those on the lower side, so that the adjustment of the solar irradiation area is more delicate. When not all the push blocks 301 are working, the non-working push blocks 301 will abut against the limit frame 34 and be driven to move up a certain distance before the working push blocks 301 can be stuck in the slots 38. However, when the threaded rod 39 rotates forward to drive the push blocks 301 to move downward, the non-working push blocks 301 will first abut against the abutment frame 33 and be driven to move down a certain distance before the working push blocks 301 will abut against the abutment frame 33. The upward and downward distances are balanced, so that the spacing between all the push blocks 301 will not be affected. At the same time, when there are more groups of solar collector panels 31 and light-transmitting holes 32, the abutment frame 33 and the threaded rod 39 can be extended to the solar photovoltaic frame 21 for the push blocks 301 to move.

[0044] In one embodiment, see Figure 4 and Figure 8 The mobile heat collecting panel 35 and the mobile photovoltaic panel 37 are both slidably connected to the limit frame 34 through the card block 51. The limit frame 34 is equipped with a limit block 52. The limit block 52 is matched with the card block 51 on the mobile photovoltaic panel 37. The width of the card block 51 is greater than the width of the card slot 38.

[0045] By adopting the above technical solution, a card block 51 is also installed at the lower part of the mobile photovoltaic panel 37 at the bottom, and is limited by its abutment with the limit frame 34. Except for the mobile photovoltaic panel 37 at the bottom, the other mobile photovoltaic panels 37 have only the card block 51 installed on the upper side. The card block 51 abuts and cooperates with the limit block 52, so that the mobile photovoltaic panel 37 can be limited and clamped. The significance of this arrangement is that the limit block 52 can be set higher, so that when the card block 51 on the mobile solar collector panel 35 on the lower side moves up, it will not collide with the limit block 52.

[0046] In one embodiment, please refer to Figure 3 The driving mechanism 4 includes a rotary driving device 41 and a belt transmission assembly 42. The rotary driving device 41 can be a servo motor. The rotary driving device 41 is installed on the solar heat collection rack 22. The output end of the rotary driving device 41 is in transmission connection with one of the threaded rods 39, and adjacent threaded rods 39 are in transmission connection through the belt transmission assembly 42.

[0047] By adopting the above technical solution, the threaded rod 39 can be driven to rotate by the rotary driving device 41, and multiple threaded rods 39 can be driven to rotate through the transmission of the belt transmission assembly 42. The rotary driving device 41 can be selected according to the actual situation, and more than one rotary driving device 41 can be used to drive the threaded rod 39.

[0048] In one embodiment, a stop block 53 is installed on the sliding plate 303, and a chamfer is provided on the sliding plate 303.

[0049] By adopting the above technical solution, the chamfer provided on the sliding plate 303 increases the contact area between the pushing block 301 and it, enabling the pushing block 301 to drive the sliding plate 303 to move upward. The stop block 53 provides a guarantee for the pushing block 301 to drive the sliding plate 303 to move upward, that is, through the extrusion drive of the pushing block 301 on the stop block 53, the sliding plate 303 can be driven to move upward. Similarly, when the sliding plate 303 moves to the uppermost end of the sliding groove 302, the threaded rod 39 needs to drive the pushing block 301 to rotate forward to a certain extent, so that the pushing block 301 can move away from the sliding plate 303, and thus the pushing block 301 no longer limits the stop block 53, enabling the sliding plate 303 and the stop block 53 to slide back to their original positions.

[0050] In one embodiment, a thermometer 54 is installed in the housing 1, and a liquid level gauge 55 and a water temperature gauge 56 are installed in the heat preservation bucket 24. The thermometer 54, the liquid level gauge 55, and the water temperature gauge 56 are all in signal connection with the rotary driving device 41 through a signal processor.

[0051] By adopting the above technical solution, the thermometer 54, the liquid level gauge 55, and the water temperature gauge 56 are all existing technologies. Through the settings of the thermometer 54, the liquid level gauge 55, and the water temperature gauge 56, the temperature inside the housing 1, the temperature and water level inside the heat preservation bucket 24 can be detected, so as to intelligently control whether hot water enters the heat preservation bucket 24 and whether the adjusting mechanism 3 performs adjustment.

[0052] In one embodiment, the output end of the rotary driving device 41 is in transmission connection with one of the threaded rods 39 through a coupling 57.

[0053] By adopting the above technical solution, it is convenient for the rotary driving device 41 to drive the threaded rod 39 to rotate.

[0054] In one embodiment, the abutting frame 33 is provided with chamfers, and a plurality of universal beads 58 are rotatably mounted on the abutting frame 33. The universal beads 58 are arranged in cooperation with the push block 301.

[0055] By adopting the above technical solution, when the push block 301 moves downward, it can abut against the universal beads 58, thereby reducing the friction between the push block 301 and the abutting frame 33.

[0056] The technical features of the above embodiments can be combined arbitrarily.
