Description

Technical Field

[0001] The present invention relates to the technical field of solar collectors, and specifically to a heat-absorbing fin plate for a medium-temperature solar collector. Background Art

[0002] The working temperature of traditional solar water heaters is generally lower than 80°C, belonging to the low-temperature solar thermal utilization with basically mature technology. While solar cooling, industrial heat use, seawater desalination, etc. require a temperature of 80 - 250°C, belonging to the medium-temperature solar thermal utilization range. The structure of a medium-temperature solar collector mainly includes the following parts: a heat-absorbing fin plate, a sealing rubber ring, a heat-collecting tube, a heat-insulating layer, and a photovoltaic-complementary heat-insulating layer.

[0003] The existing heat-absorbing fin plate is installed inside a vacuum frame and sealed by a seal. After long-term use of the medium-temperature solar collector, the seal will be damaged, causing external air to carry water vapor into the frame. The water vapor inside the frame will refract light, and when the temperature drops at night, the water vapor will condense on the surfaces of the heat-absorbing fin plate and the heat-collecting tube. The condensed water droplets will also reduce the heat conduction speed, resulting in a decrease in the heating efficiency of the medium-temperature collector. Summary of the Invention

[0018] The battery is fixedly mounted on one side of the connecting plate;

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. When the first electric push rod contracts, the flap plate flips inward, so that the roller is in contact with the surface of the heat absorption tube. When the third motor operates, the roller rotates while being in contact with the surface of the heat absorption tube, driving the wiping assembly to move. Thus, by providing a deployable wiping assembly on the surface of the heat absorption fin plate and the heat conduction tube, the sponge block adsorbs the water droplets on the surface of the heat absorption fin plate and the heat absorption tube. When it is necessary to adjust the position of the wiping assembly, the first electric push rod extends, causing the flap plate to flip and be flush with the cross plate, facilitating the connecting plate to drive its rotating plate and at the same time avoiding interfering with the rotation of the deployed wiping assembly.

[0035] 2. When the second motor operates, driving the winding drum to rotate, when one of the two pull ropes is released and the other is wound up, multiple second pressing plates squeeze the sponge block to be in contact with the heat absorption tube and the heat absorption fin plate. Conversely, when the winding drum rotates in the opposite direction, the multiple second pressing plates remain flush, facilitating the grooved drain pipe to squeeze out the water inside the sponge block.

[0036] 3. The first motor operates, causing the T-shaped rotating rod, the deployed wiping assembly, and the moving assembly to rotate. At the same time, the grooved drain pipe moves downward, squeezing the water inside the sponge block. Meanwhile, the first motor that clamps the wiping assembly at the heat absorption pipe also rotates. With the T-shaped rotating rod fixed, the connecting plate as a whole rotates, moving the deployed wiping assembly to the surface of another heat absorption pipe, thereby adjusting the position of the wiping assembly so that it can wipe the water on the surfaces of the heat absorption pipes and the heat absorption fin plates at different positions.

[0037] 4. When treating the water inside the sponge block, the second electric push rod extends to adjust the position of the inclined plate, causing the grooved drain pipe to move downward in parallel, so that the grooved drain pipe squeezes the water inside the sponge block, and then the water droplets discharged from the inside of the grooved drain pipe fall into the drain trough. Then the solenoid valve opens to discharge the water inside the drain trough. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figure 1-8, in the embodiments of the present invention, a heat-absorbing fin plate of a medium-temperature solar collector includes a heat-absorbing fin plate 1. A frame 102 for installing the heat-absorbing fin plate 1 is arranged outside the heat-absorbing fin plate 1. A heat-absorbing tube 101 is fixedly installed on one surface of the heat-absorbing fin plate 1. A drain groove 103 is formed on the lower surface inside the frame 102. A solenoid valve 104 communicating with the drain groove 103 is fixedly embedded on one surface of the frame 102. The water droplets discharged from the inside of the slotted drain pipe 607 fall into the drain groove 103, and then the solenoid valve 104 is opened to discharge the water inside the drain groove 103. A connecting component 2 is arranged inside the frame 102. Two wiping components 3 are movably arranged below the connecting component 2. The wiping component 3 includes a T-shaped rotating rod 301. A first pressing plate 304 is fixedly installed at the lower end of the T-shaped rotating rod 301. A plurality of second pressing plates 305 are symmetrically and movably arranged on both sides of the first pressing plate 304. Sponge blocks 309 are fixedly installed on one surface of the first pressing plate 304 and the second pressing plates 305. An adjusting component 4 is arranged outside the wiping component 3 for adjusting the angle of the second pressing plate 305. Two moving components 5 are arranged at the other end of the T-shaped rotating rod 301 for driving the wiping component 3 to move. Two drainage components 6 are arranged on both sides of the connecting component 2. The drainage component 6 includes an inclined plate 601. U-shaped seats 602 are symmetrically and fixedly installed at both ends of the inclined plate 601. A second rotating rod 603 is rotatably connected inside one U-shaped seat 602. Two third rotating rods are rotatably connected inside the other U-shaped seat 602. A slotted drain pipe 607 is fixedly installed at one end of the second rotating rod 603. Notches are formed on the surface of the slotted drain pipe 607, so that the upper end of the notch scrapes across the sponge block 309 to squeeze out the water inside the sponge block 309.

[0049] Specifically, a humidity sensor is arranged inside the frame 102. When the humidity sensor senses an increase in the humidity inside the frame, that is, the seal of the frame 102 is damaged and the outside air carries water vapor into the frame 102. When the temperature drops at night, the water vapor condenses on the surfaces of the heat-absorbing tube 101 and the heat-absorbing fin plate 1. The moving component 5 is controlled to drive the wiping component 3 to move along the heat-absorbing tube 101, so that the wiping component 3 wipes the water droplets on the surfaces of the heat-absorbing fin plate 1 and the heat-absorbing tube 101, and then the water inside the sponge block 309 is discharged through the drainage component 6.

[0050] Embodiment 1

[0051] As Figure 1-3 shown, in this embodiment, the connecting component 2 includes a connecting plate 201. Two bearings 202 are fixedly embedded on one surface of the connecting plate 201. A battery 203 is fixedly installed on one surface of the connecting plate 201. Two conductive plugs 204 are respectively fixedly installed on the inner surface of the frame 102 and one surface of the connecting plate 201.

[0052] In this embodiment, the conductive plug 204 installed on the inner surface of the frame 102 is connected to a power source. When the two conductive plugs 204 are in contact, they are electrically connected to charge the battery 203.

[0053] As Figure 4 and Figure 7 shown, in this embodiment, the moving component 5 includes: a cross plate 501 fixedly installed at the other end of the T-shaped rotating rod 301; two flap plates 502 symmetrically hinged at both ends of the cross plate 501; a plurality of rollers 503 symmetrically rotatably connected to both sides of the flap plates 502; and a bidirectional connection seat 508 fixedly installed on one side surface of the cross plate 501. Inside the bidirectional connection seat 508, a first electric push rod 507 is symmetrically rotatably connected. A first connection seat 506 is fixedly installed on one side surface of the flap plate 502. One end of the first electric push rod 507 is rotatably connected to the first connection seat 506 at the corresponding position. On one side of the flap plate 502, a third motor 504 is fixedly installed through a bracket. The output end of the third motor 504 and one end of a roller 503 are fixedly installed with a second gear 505 in meshing transmission connection.

[0054] During specific implementation, when the first electric push rod 507 contracts, through its rotational connections with the first connection seat 506 and the bidirectional connection seat 508, and through the hinge connection between the cross plate 501 and the flap plate 502, the flap plate 502 is flipped inward, so that the roller 503 is in contact with the surface of the heat absorption tube 101. When the third motor 504 operates, through the meshing transmission of the second gear 505, the roller 503 rotates while being in contact with the surface of the heat absorption tube 102, driving the wiping component 3 to move. Thus, by providing a deployable wiping component 3 on the surfaces of the heat absorption fin plate 1 and the heat conduction tube 101, the sponge block 309 adsorbs the water droplets on the surfaces of the heat absorption fin plate 1 and the heat absorption tube 101. When it is necessary to adjust the position of the wiping component 3, the first electric push rod 507 extends, causing the flap plate 502 to flip and be flush with the cross plate 501, facilitating the connecting plate 201 to drive its rotating plate, and at the same time avoiding interfering with the rotation of the deployed wiping component 3.

[0055] As Figure 5 and Figure 6 shown, in this embodiment, the adjusting component 4 includes: a fixing frame 401 fixedly installed on one side surface of a second pressing plate 305; a winding drum 403 rotatably connected inside the fixing frame 401; and a second motor 402 fixedly installed on one side surface of the fixing frame 401. Two pull ropes 404 are wound around the outer surface of the winding drum 403. One pull rope 404 is respectively fixedly connected to the first pressing plate 304 and the second pressing plate 305 on one side. A limiting ring 405 is fixedly installed on one side surface of a second pressing plate 305. The other pull rope 404 passes through the limiting ring 405 and is fixedly connected to the outermost second pressing plate 305.

[0056] In a specific implementation, the second motor 402 is running, driving the winding drum 403 to rotate, so that the two pull ropes 404 move in opposite directions. When one of the two pull ropes 404 is released and the other is wound up, under the reset action of the coil spring 308, the plurality of second pressure plates 305 are turned over, and the direction of the rewinding and resetting force of the coil spring 308 is adjusted to make the outermost second pressure plate 305 rotate in the opposite direction, so that the plurality of second pressure plates 305 squeeze the sponge block 309 to fit the heat absorption tube 101 and the heat absorption fin plate 1 (as shown in the attached manual). Figure 4 As shown), on the contrary, when the winding drum 403 rotates in the opposite direction, a pull rope 404 is wound up, and multiple No. 2 pressure plates 305 are pulled straight to the same plane, and another pull rope 404 is released, so that the outermost No. 2 pressure plate 305 is rotated in the opposite direction under the reset action of the coil spring 308, and keeps it flush with other No. 2 pressure plates 305, so that the slotted drain pipe 607 can squeeze out the water inside the sponge block 309.

[0057] like Figure 4-6 As shown, in the present embodiment, a T-shaped rotating rod 301 is fixedly installed through the inner ring of the bearing 202 at the corresponding position, and a No. 1 motor 302 is fixedly installed on one side surface of the connecting plate 201 through a bracket, and two No. 1 gears 303 connected in meshing transmission are fixedly installed on the output end of the No. 1 motor 302 and the outer surface of the T-shaped rotating rod 301; a No. 1 pressure plate 304 and a No. 2 pressure plate 305 are fixedly installed with a collar 307 at one end, and a No. 1 rotating rod 306 is rotatably connected inside the collar 307, and one end of the No. 1 rotating rod 306 is fixedly connected to the No. 2 pressure plate 305, and a coil spring 308 is fixedly installed on one side surface of the collar 307, and one end of the coil spring 308 is fixedly connected to the No. 1 rotating rod 306 at the corresponding position, and a limit plate 7 is fixedly installed on one end of the No. 2 pressure plate 305, and the limit plate 7 limits the maximum flipping angle of the No. 2 pressure plate 305, so as to facilitate the No. 1 pressure plate 304 and the No. 2 pressure plate 305 to flip to a flush state.

[0058] During specific implementation, the No. 2 pressure plate 305 can be flipped over through the rotation connection of the No. 1 rotating rod 306 and the ring 307, and the No. 1 motor 302 is running. Through the meshing transmission of the No. 1 gear 303, the T-shaped rotating rod 301, the unfolded wiping assembly 3 and the moving assembly 5 are rotated, and at the same time, the slotted drain pipe 607 moves downward to squeeze out the water inside the sponge block 309. At the same time, the No. 1 motor 302 that clamps the wiping assembly 3 at the heat absorption tube 101 also rotates at the same time. Through the fixation of the T-shaped rotating rod 301, the connecting plate 201 is rotated as a whole, and the unfolded wiping assembly 3 is moved to the surface of another heat absorption tube 101, thereby adjusting the position of the wiping assembly 3 so that it can wipe the water on the surfaces of the heat absorption tubes 101 and the heat absorption fin plate 1 at different positions.

[0059] Embodiment 2

[0060] On the basis of the first embodiment, in order to make up for the problem that the water inside the sponge block 309 in the first embodiment is difficult to discharge.

[0061] like Figure 3 and Figure 8 As shown, in this embodiment, a No. 3 rotating rod at the top is fixedly connected to the connecting plate 201, and a No. 3 gear 608 is fixedly installed at one end of the No. 2 rotating rod 603 and the No. 3 rotating rod, and a No. 2 electric push rod 605 is fixedly installed on one side surface of the inclined plate 601, and a plurality of fixed rings 604 are fixedly installed on the outer surface of the inclined plate 601, and push rods 609 are slidably connected inside the plurality of fixed rings 604, and racks 606 are symmetrically fixedly installed at both ends of the push rods 609, and the racks 606 are meshingly connected to the No. 3 gear 608 at the corresponding position for transmission, and the two adjacent No. 3 gears 608 are meshingly connected for transmission.

[0062] In specific implementation, when the water inside the sponge block 309 is processed, the No. 2 electric push rod 605 extends, driving the two racks 606 to move, causing the No. 3 gear 608 meshing with them to rotate, and one No. 3 gear 608 drives the No. 2 rotating rod 603 to rotate, causing the slotted drain pipe 607 to move downward in parallel. When the other No. 3 gear 608 rotates, it is connected to the remaining fixed No. 3 gear 608 through meshing transmission, so that the other No. 3 gear 608 rotates around the fixed No. 3 gear 608, and the position of the inclined plate 601 is adjusted to move the slotted drain pipe 607 downward, so that the slotted drain pipe 607 squeezes out the water inside the sponge block 309, and then the water discharged from the slotted drain pipe 607 drips into the drain trough 103, and then the solenoid valve 104 opens to discharge the water inside the drain trough 103.

[0063] In the present invention, in order to facilitate the operator to control the invention, a PLC controller can be set up, and the solenoid valve 104, motor No. 1 302, motor No. 2 402, motor No. 3 504, electric push rod No. 1 507, electric push rod No. 2 605 and humidity sensor are all electrically connected to the PLC controller. The PLC controller is a prior art and will not be described in detail here.

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0065] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
