Description

Technical Field

[0001] The invention relates to the technical field of solar energy system cleaning, in particular to a dust and snow removal device suitable for solar energy systems in high-altitude and cold regions. Background Art

[0002] In common solar energy systems, concentrators and solar panels are arranged outdoors, and dust and other dirt will inevitably accumulate on their surfaces, affecting the heat collection performance of the concentrators and the power generation efficiency of the solar panels. This is especially true in high-altitude and cold regions, where there is snowfall and possible icing in winter, and there may also be ice at the bottom of the snow. When dust and ice are mixed, they are more difficult to clean, which has a more serious impact on the concentrators and solar panels.

[0003] Currently, dust removal technologies for solar systems are primarily categorized as contact and non-contact. Contact methods utilize tools like scrapers and brushes. Non-contact methods primarily utilize airflow, liquid flow, electric field forces, and other techniques for dust removal. These methods primarily rely on nozzles. Commonly used nozzles include those with flow guides, which consume high energy and offer limited efficiency. Other methods utilize physical methods such as pressure boost holes to adjust the air volume, but these methods suffer from poor adaptability and the inability to automatically adjust the volume in real time. Other methods utilize rotating mechanisms or flanges to increase air coverage, but these methods offer limited functionality. Contact methods, due to the inevitable compressive contact that can cause a certain degree of mirror wear, are currently the predominant method.

[0004] Most current snow removal methods utilize shovel brushes, snow throwers, brush heads, scrapers, and heating wires. These brushes, brush heads, and scrapers can easily damage the mirror surface over time, and they fail to account for the presence of ice beneath the snow during northern winters. Heating wires lack automatic direction control, and most systems utilize large, fixed heating surfaces. A few mobile heating wires are used within rollers, but these systems lack consideration for heat transfer and are inefficient. Furthermore, problems can easily arise if the equipment is left outdoors for extended periods outside of winter. Furthermore, since most de-icing methods utilize hot air blowers or physical ice crushing, these methods suffer from high energy consumption, poor results, and potential damage to the mirror surface.

The front end of the connecting pipe 53 is the input end of the multifunctional pipeline controller 52, and the rear end of the connecting pipe 53 is the output end of the multifunctional pipeline controller 52. The installation bin 54 is provided with a pressurizing device 55, an ionization device 56, and a controllable flow plate device 57 from front to back, and the components in the installation bin 54 can be partially disassembled for easy maintenance.

[0034] Furthermore, the pressurizing device 55 includes a movable ring 551 installed on the rotating shaft 58 and capable of sliding along the rotating shaft 58. The rotating shaft 58 is rotatably connected to the mounting bin 54. A third lifting device 552 is vertically provided at the bottom of the outer wall of the movable ring 551. A support member 553 is horizontally provided at the bottom of the third lifting device 552. A driving motor 554 is provided on the support member 553.

During the formal operation, the pressure of the fluid in the pipe is detected by the sensor, and the control signal is transmitted in real time so that the system controls the speed of the pressurizing blade 555 to achieve a certain pressurization effect.

[0035] An auxiliary rotating handle is provided on the outside of the installation chamber 54, and the auxiliary rotating handle is installed on the rotating shaft 58. When it cannot be controlled by the control system or there is no power, the rotating shaft 58 can be manually rotated to rotate the equipment back to the correct position of the upper half of the installation chamber 54. The multifunctional cabin shell is in the shape of a rectangular parallelepiped and is fixed to the wall of the pipe.

[0036] Furthermore, the ionization device 56 includes an ionization gas delivery pipe 561, an electric shielding shell 562, and an energizing device 563 arranged in sequence from bottom to top. One end of the ionization gas delivery pipe 561 is connected to the connecting pipe 53, and the other end is connected to the electric shielding shell 562. A tip discharger 564 and an air supply device 565 are provided in the electric shielding shell 562 from top to bottom. The tip discharger 564 is electrically connected to the energizing device 563. During operation, the cleaning effect of the mirror is detected by a sensor. If the expected level cannot be achieved, the ionization device 56 is started. First, a 220V voltage is passed through the energizing device 563 to transmit the current to the tip of the tip discharger 564, so that the air near the tip is ionized, and then the air supply device 565 is started. The air supply device 565 includes an air supply device base, an air supply device shaft, an air supply device body, an air supply hole, an air supply device rotating shaft and a fan blade part.

[0037] Furthermore, the controllable flow plate device 57 includes a controllable movable flow plate base 571 installed on the rotating shaft 58 and capable of sliding along the rotating shaft 58, the bottom of the controllable movable flow plate base 571 is provided with a rotating device 572, the bottom of the rotating device 572 is provided with a flow plate outer ring telescopic base 573, the inner side of the flow plate outer ring telescopic base 573 is provided with a flow plate first telescopic layer 574, the inner side of the flow plate first telescopic layer 574 is provided with a flow plate second telescopic layer 575, the outer wall of the connecting pipe 53 is provided with a second opening 576 for the controllable flow plate device 57 to enter and exit, and a second electric opening and closing door 577 for closing the second opening 576. The controller controls the horizontal movement of its controllable, movable flow plate base 571, with the left side controlled by a limiter (right portion) and the right side controlled by the left end face of the retractable, controllable hatch on the right side of the flow plate.

The outer diameter of the flow plate's outer ring telescopic base 573 is equal to the inner diameter of the fluid pipeline, and during operation, it conforms to the inner wall of the pipeline. The flow rate is controlled according to the flow and pressure detected by the sensor. Specifically, the center hole size is controlled by the expansion and contraction of the flow plate's first and second telescopic layers 574 and 575, thereby controlling the flow rate. The first and second telescopic layers are controlled by the controller to extend from the slots in the outer ring telescopic base of the flow plate toward the center of the circle. At maximum extension, the first and second telescopic layers 574 and 575 can cooperate to completely close the internal passage of the pipeline, achieving the purpose of temporarily sealing the pipeline outlet through the device, thereby facilitating maintenance and other work on other pipeline sections. During operation, the second electric opening and closing doors 577 on the left and right sides are closed and fit tightly with the hatch card to form a closed space.

[0038] Preferably, the inner diameter of the nozzle 51 increases from front to back, and a plurality of pressure diffuser microchannel groups are provided on the rear end face of the nozzle 51.

The nozzle head is specially designed at the end cross section, with nozzle head pressure diffuser microchannels 511 having a gradually expanding shape and distributed in a circular array on the nozzle head. The flow channel extends from the end portion of the nozzle head to the end cross section, and the cross section shows that the nozzle head pressure diffuser holes are dense at the center of the circle, expand along the radius, and gradually become sparse. This achieves a brief secondary pressurization process at the nozzle head, improving the final airflow cleaning efficiency.

[0039] The dust and snow removal composite assembly 6 includes a mounting base 61 fixed to the end of the second robotic arm 4, a support shaft 62 arranged on the mounting base 61 and rotatably connected to the mounting base 61, and a first driving mechanism for driving the support shaft 62 to rotate. The entire dust and snow removal composite assembly 6 achieves rotational operation by rotating the support shaft 62. A number of functional parts 63 are evenly arranged on the outer peripheral wall of the support shaft 62 along the circumference of the support shaft 62; the functional parts 63 include a support seat 631, the support seat 631 is fixed on the support shaft 62, and two mounting grooves 632 are provided on the side of the support seat 631 away from the support shaft 62, one of the mounting grooves 632 is provided with a scraper assembly 633, and the other mounting groove 632 is provided with a negative pressure adsorption assembly 634, and the scraper 6331 of the scraper assembly 633 and the negative pressure rubber roller 6341 of the negative pressure adsorption assembly 634 can both extend out of the mounting groove 632 or be retracted into the mounting groove 632, and a number of suction ports 6342 are provided on the outer wall of the negative pressure rubber roller 6341, and the moving device 1 is provided with a negative pressure manufacturing device 12 for providing negative pressure to the inner cavity of the negative pressure rubber roller 6341, and an electric heating assembly 635 is provided between the two mounting grooves 632.

[0040] Preferably, a recess 636 for mounting an electric heating assembly 635 is provided on the side of the support base 631 away from the support shaft 62. The electric heating assembly 635 includes, in order from bottom to top, a thermal insulation layer 6351, a heating chamber 6352, and a heat-conducting radiation plate 6353 disposed within the recess 636. An electric infrared heating element 6354 is disposed within the heating chamber 6352. The entire electric infrared heating element 6354 is configured to be detachable, and the silicon carbide tube of the main body of the electric infrared heating element 6354 is also configured as a detachable structure, mounted in the middle of the heating chamber 6352 and secured at both ends by a tight fitting. The heat-conducting radiation plate 6353 can maximize the uniformity of radiated heat directed to the target object within a certain wavelength range. This design is used for clearing ice.

[0041] A control method for an automatically controlled plate-type electric infrared heater, also known as a deicing mechanism, includes a temperature sensor at the front end of the heater, a depth sensor, a controller, and a heating chamber temperature detector. The heating element is made of silicon carbide and can generally be maintained at a temperature of around 200°C to achieve deicing.

[0042] Theoretical total heat of radiation heat transfer: Q = 0.6 × 5.67 × 10S (T1 4 -T2 4 )

[0043] T1, T2: absolute temperature of the radiator and absorber (K), S is the surface area of the object;

[0044] The displacement sensor at the front end of the robotic arm measures the mirror portion of the temperature sensor where the temperature is below 0°C and the depth sensor is greater than the set value H0 (H0 is the maximum thickness range of dust and impurities on the surface in a normal non-icing state). The measured length L1, width W1, and depth H1 are simplified to calculate their volume as V = L1 × W1 × H1. Internal data is used to calculate the total mass of the ice M1 = Vρ (ρ is the density of ice). The heat absorbed when ice is converted into water is 334,000 J per kilogram, and the theoretical heat absorbed when converted into water is Q1 = 334,000M1. The theoretically required radiation energy Q2 is calculated based on the radiation heat transfer formula. Taking into account issues such as the conversion of electrical energy into thermal energy and the loss of radiation heat transfer, the overall efficiency is set at 0.7. The operating time is T = Q1 / (Q2×0.7). Once the operating time reaches T, the surface material depth and temperature are immediately detected. The detection depth is H2 and the temperature is T2. When the depth H2 is between 0 and H0 and the temperature T2 is greater than 0, the heater is activated to evaporate residual water. When the temperature T2 is less than 0, the dust blowing device is activated to clear residual water with gas. This control system can significantly reduce energy consumption and save costs.

The first lifting device 6343 is controlled by the controller to extend or shorten to complete the pre-processing task of normal operation. The negative pressure air pipe is connected to the negative pressure manufacturing device 12. The pressure sensor of the negative pressure rubber roller 6341 monitors the gas pressure in the inner cavity at all times. When the negative pressure is not enough for adsorption, the data will be transmitted to the controller to increase the power of the negative pressure manufacturing device. To a certain extent, the gas pressure in the cavity created by the negative pressure manufacturing device 12 is controlled to be stable within a certain range of values. Continuous negative pressure enters the cavity inside the negative pressure rubber roller 6341, creating a certain negative pressure environment, and then absorbs fine dust on the mirror surface through the suction port 6342 on the surface of the rubber roller. The negative pressure rubber roller 6341 can be disassembled, and there is an intelligent controllable rubber roller unloading plate 6344 at the bottom. When too much dust and impurities are accumulated inside, the control system will be started to automatically open the unloading port, and the interior will be deeply cleaned by the material's own gravity or the nozzle of the equipment to complete the subsequent internal cavity dust cleaning work.

The blade seat is hinged to the blade connecting frame 6333, and a second drive device is provided on the blade connecting frame 6333 for rotating the blade seat. The first drive device is responsible for adjusting the mirror angle and rotating it to a certain angle, while the second drive device finely adjusts the angle of the front blade 6331. A distance sensor is provided on the side of the blade 6331 to monitor the distance from the mirror surface to prevent excessive pressure and wear on the mirror surface. All drive devices of the blade assembly 6333 are remotely controlled by a controller to achieve rotation with a certain degree of precision.

[0047] Preferably, the head portion of the scraper 6331 uses a bronze-graphite composite blade, and the surface of the scraper 6331 is provided with a chrome-plated layer; the rubber portion of the surface of the negative pressure rubber roller 6341 is added with polydimethylsiloxane and modified silicone resin. The head portion of the scraper 6331 uses a bronze-graphite composite material with a chrome-plated surface. The chrome plating can reduce the friction of the blade. Considering the hardness and strength of the overall blade, the graphite content is controlled between 2-5%; the surface of the negative pressure rubber roller 6341 is coated with a durable and sticky coating with polydimethylsiloxane and modified silicone resin (fluorinated modification), which can adhere to dust on the mirror surface during rolling. The entire rubber roller part uses negative pressure adsorption and surface adhesion to achieve the effect of efficient dust removal.

[0048] The surfaces of the shovel blade 6331 and the negative pressure rubber roller 6341 are both provided with distance sensors. The controller processes the information through the transmission of distance data, and the first lifting device 6343 and the second lifting device 6332 are connected to the controller (the lifting mechanism and the lifting device in this embodiment can both use electric push rods) to control the extension and retraction of the two. When extended, the actually used part extends out of the slot by a certain distance. The external temperature sensor of the electric infrared heating element 6354 is a common temperature sensor for the entire dust and snow removal composite device. By detecting the ambient temperature and the mirror temperature and comparing them with the set temperature range, within a certain error range, the purpose of using the shovel blade 6331 and the electric heating component 635 in winter and using the negative pressure rubber roller 6341 in non-winter can be achieved, thereby making full use of the equipment.
