Description

Technical Field

[0001] The present invention relates to the technical field of solar collectors, and particularly to a heat absorption fin plate of 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 scope of medium-temperature solar thermal utilization. The structure of a medium-temperature solar collector mainly includes the following parts: a heat absorption fin plate, a sealing rubber ring, a heat collection tube, a heat insulation layer, and a photovoltaic complementary heat insulation layer.

[0003] The existing heat absorption 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, resulting in the entry of external air carrying 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 absorption fin plate and the heat collection tube.

[0017] 3. Motor No. 1 runs to rotate the T-shaped rotating rod, the unfolded wiping assembly and the moving assembly, and at the same time the slotted drain pipe moves downward to squeeze out the water inside the sponge block. At the same time, motor No. 1 that clamps the wiping assembly at the heat absorbing tube also rotates at the same time. By fixing the T-shaped rotating rod, the connecting plate rotates as a whole, and the unfolded wiping assembly is moved to the surface of another heat absorbing tube, thereby adjusting the position of the wiping assembly so that it can wipe the water on the surfaces of the heat absorbing tubes and heat absorbing fins at different positions.

[0018] 4. When processing the water inside the sponge block, the No. 2 electric push rod extends and adjusts the position of the inclined plate to make the slotted drain pipe move downward in parallel, so that the slotted drain pipe squeezes out the water inside the sponge block, and then the water discharged from the slotted drain pipe drips into the drain trough, and then the solenoid valve opens to drain the water inside the drain trough.

Specific embodiments

[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] 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 on the outer side of 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 grooved 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. One end of the second rotating rod 603 is fixedly installed with a grooved drain pipe 607. Notches are formed on the surface of the grooved 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.

[0023] 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 at the sealed part 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.

[0024] Embodiment 1

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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 to make the roller 503 fit on 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 fitting on the surface of the heat absorption tube 102, driving the wiping component 3 to move. Thus, by arranging the 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 to flip the flap plate 502 to 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.

[0029] 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 fixedly connected to the first pressing plate 304 and the second pressing plate 305 on one side respectively. 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Embodiment 2

[0034] 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 not easy to drain.

[0035] As Figure 3 and Figure 8 shown, in this embodiment, the uppermost third rotating rod is fixedly connected to the connecting plate 201. Third gears 608 are fixedly installed at one ends of the second rotating rod 603 and the third rotating rod. A second electric push rod 605 is fixedly installed on one side surface of the inclined plate 601. A plurality of fixing rings 604 are fixedly installed on the outer surface of the inclined plate 601. A push rod 609 is slidably connected inside the plurality of fixing rings 604. Rack bars 606 are symmetrically fixedly installed at both ends of the push rod 609. The rack bars 606 are in meshing transmission connection with the third gears 608 at the corresponding positions, and two adjacent third gears 608 are in meshing transmission connection.

[0036] During specific implementation, when treating the water inside the sponge block 309, the second electric push rod 605 extends, driving the two rack bars 606 to move, so as to rub and drive the third gears 608 meshed therewith to rotate. One third gear 608 drives the second rotating rod 603 to rotate, so that the grooved drain pipe 607 moves down parallelly. When the other third gear 608 rotates, through the meshing transmission connection with the remaining stationary third gear 608, the other third gear 608 rotates around the stationary third gear 608 to adjust the position of the inclined plate 601, so that the grooved drain pipe 607 moves down, thereby squeezing out the water inside the sponge block 309 by the grooved drain pipe 607. Then the water droplets discharged from the inside of the grooved drain pipe 607 fall into the drain tank 103, and then the solenoid valve 104 is opened to discharge the water inside the drain tank 103.

[0037] In the present invention, in order to facilitate the operator to control the invention, a PLC controller can be set. The solenoid valve 104, the first motor 302, the second motor 402, the third motor 504, the first electric push rod 507, the second electric push rod 605 and the humidity sensor are all electrically connected to the PLC controller. The PLC controller is a prior art and will not be elaborated here.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0039] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative way 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.
