Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic pumping stations, and in particular to a concentrating and heat-collecting photovoltaic intelligent pumping station. Background Art

[0002] The photovoltaic intelligent pumping station is a solar-powered, intelligent pumping station system designed specifically for green energy applications. Leveraging its energy-saving efficiency and intelligent control, it utilizes both photoelectric and photothermal conversion to demonstrate significant value in agricultural irrigation, mountain water supply, and ecological water replenishment.

[0003] During agricultural irrigation operations, photovoltaic panels use intelligent control devices to track sunlight in real time and perform photoelectric conversion to provide power to intelligent pumping stations. Agricultural irrigation is mostly carried out outdoors and during the dry season. Photovoltaic intelligent pumping stations are widely promoted and applied as a water-saving sprinkler irrigation equipment. Since irrigation water is usually directly pumped from lakes and rivers using water pumps, and due to the presence of a lot of aquatic plants and other debris in rivers and lakes, the water inlet of the pump is prone to blockage during operation, causing the pump to shut down, affecting the timely irrigation of dry season crops, and further affecting the normal growth of crops. To address the above problems, the existing technology has a better solution. By setting an impurity crushing mechanism in the pipeline, it is possible to crush impurities in the pumped water flow, preventing impurities from causing pump blockage, ensuring the normal use of the photovoltaic intelligent pumping station while achieving timely irrigation of dry season crops, and further ensuring the normal growth of dry season crops. However, the following drawbacks still exist: In Yunnan, many photovoltaic pumping stations are used to irrigate crops during the dry season. Since Yunnan's dry season mostly occurs in winter and spring (November to May of the following year), the ambient temperature is relatively low. When irrigating crops planted in early spring (such as spring wheat and spring potatoes), if the water temperature is too low, it will inhibit seed germination and seedling growth, prolong the growth cycle, and increase the risk of pests and diseases. Therefore, the irrigation water in the pumping station water tank needs to be heated to ensure the normal growth of crops planted in early spring. However, long-term heating treatment will reduce the solubility of calcium and magnesium ions in the water, causing scale to precipitate in the water tank. The precipitated scale will be irrigated into the soil with the water flow and adhere to the surface of the crop root system, forming an impermeable and airtight barrier, hindering the root system from absorbing gas and water from the soil, which will also affect the normal growth of the crop.

[0004] Therefore, in order to solve the above problems, a concentrating and thermal photovoltaic intelligent pumping station is proposed. Summary of the Invention

[0005] The present invention aims to provide a concentrated solar-thermal photovoltaic intelligent pumping station that addresses the problem of scale deposited during heating adhering to crop roots after being irrigated into the soil, thereby affecting their normal growth. By providing a heat-collecting mechanism, a gathering mechanism, and a scale-shoveling mechanism, the station can simultaneously heat irrigation water in both winter and spring while improving heating efficiency. Furthermore, the gathering and scale-shoveling mechanisms are used to clean and filter scale deposited in the transfer barrel due to prolonged heating. This ensures the transfer barrel's heat conductivity while uniformly heating the irrigation water in the transfer barrel through photothermal conversion using photovoltaic panels. Furthermore, this prevents scale deposited during prolonged heating from being pumped into the soil, thus providing a dual guarantee for the normal growth of early spring crops.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A concentrating and heat-collecting photovoltaic intelligent pumping station includes a photovoltaic panel and a mounting plate, as well as a heat collecting mechanism, a transfer barrel, a gathering mechanism and a scale scraping mechanism. The heat collecting mechanism is arranged on the mounting plate, and the transfer barrel is arranged on the heat collecting mechanism. The photovoltaic panel performs photoelectric conversion when exposed to light and heats the inside of the transfer barrel through the heat collecting mechanism. The gathering mechanism is arranged on the heat collecting mechanism. When the gathering mechanism is powered on and started, it rotates inside the transfer barrel and collects scale precipitated by heating inside the transfer barrel. The scale scraping mechanism is arranged on the gathering mechanism. When the load of the gathering mechanism increases to a set value, the gathering mechanism accelerates rotation and drives the scale scraping mechanism to fit the inner wall of the transfer barrel.

[0008] Preferably, the heat collection mechanism includes a fixing frame, an outer barrel, a constant temperature spiral heating tube, a heat collecting plate, a water inlet pipe and a water outlet pipe, the fixing frame is arranged on the mounting plate, the outer barrel is arranged on the fixing frame, the transfer barrel is detachably arranged inside the outer barrel, the constant temperature spiral heating tube is arranged between the transfer barrel and the outer barrel, and the space between the transfer barrel and the outer barrel is filled with pure water to avoid the constant temperature spiral heating tube from "dry burning" while being able to cooperate with pure water to expand the heating range, the heat collecting plate is arranged on the mounting plate and coaxially arranged below the outer barrel, and the bottom of the outer barrel is arranged as an outward convex The top of the heat collecting plate is set to an inwardly concave arc surface, the water inlet pipe is set at the bottom of the transfer barrel, the inner wall of the transfer barrel is fitted with a filter plate, the water outlet pipe is set on the side wall of the transfer barrel and is located at the filter plate, the water inlet pipe and the water outlet pipe are both set through the outer barrel; the water inlet pipe is movably connected to the bottom of the transfer barrel, and a sealing plate that fits the bottom of the transfer barrel is fixedly sleeved on the water inlet pipe. A sewage pipe is supported on the water inlet pipe, and a pickling pipe is set above the transfer barrel. At the same time, part of the water inlet pipe can be coiled at the bottom of the photovoltaic panel. The setting can absorb the heat absorbed by the photovoltaic panel under light conditions to preheat the water flowing in the water inlet pipe. When the pump station is used to irrigate crops in the soil under drought conditions in summer, the water inlet pipe coiled at the bottom of the photovoltaic panel can cool the photovoltaic panel to a certain extent, avoiding high temperature limiting the power generation efficiency of the photovoltaic panel. At the same time, it can avoid scalding the crops after the irrigation water is heated by shielding the heat collecting plate and closing the constant temperature spiral heating tube. The outlet pipe is movably connected to the side wall of the transfer barrel, and the fixed sleeve on the outlet pipe is provided with a sealing plate 2 and a sealing plate Third, the second sealing plate is fitted with the outer wall of the transfer barrel, and the third sealing plate is fitted with the outer wall of the outer barrel and is detachably connected to the outer barrel to facilitate the disassembly and cleaning of the transfer barrel. Water pumps are installed at the ends of the water inlet pipe and the water outlet pipe, and are used in conjunction with the transfer barrel to form a transfer pump station. The water pump installed on the water inlet pipe is used to pump water from rivers and lakes into the interior of the transfer barrel, and the water pump on the water outlet pipe is used to pump the heated water in the transfer barrel into the soil for irrigating crops. Installing water pumps on the water inlet pipe and the water outlet pipe is a conventional technical means, so it will not be described in detail.

[0009] By adopting the above solution, part of the electrical energy generated by the photovoltaic panels during photoelectric conversion can be used to heat the constant temperature spiral heating tube, and the solar collector can concentrate the sunlight under light conditions to heat the bottom of the outer barrel during the photothermal conversion process, thereby achieving double heating of the transfer barrel. In turn, the water can be heated before being pumped to the soil, avoiding the water temperature being too low and restricting the normal growth of crops.

[0010] Preferably, the gathering mechanism includes a mounting frame, a motor, a driving rod and a gathering assembly, the mounting frame is arranged on the transfer barrel, the motor is arranged on the mounting frame and the output end is connected to the driving rod, the inner circle of the filter plate is provided with a connecting frame, the connecting frame is socketed with the driving rod, the gathering assembly is arranged inside the transfer barrel and there are multiple circular arrays, the gathering assembly includes two connecting rods, two connecting plates, a filter screen and two blocks, the two connecting rods are arranged on the driving rod, the two ends of each connecting plate are respectively socketed with the corresponding connecting rod, the filter screen is arranged between the two connecting plates and connected to the two connecting plates, the filter screen is gauze, and the two blocks are respectively fixed on the corresponding connecting rods.

[0011] By adopting the above solution, when the motor is working, it can use the driving rod and the filter to drive the water in the transfer barrel to rotate, so that the heat generated by the heat collecting mechanism during heating is quickly and evenly dispersed in the transfer barrel, effectively improving the light-to-heat conversion efficiency. Moreover, since the filter is in an open state, water will pass through the filter after entering the filter, and the scale floating in the water will be filtered inside the filter, avoiding the situation where scale is scattered everywhere and pumped into the soil after the transfer barrel is heated for a long time, effectively ensuring the normal growth of crops. At the same time, by rotating the filter plate through the connecting frame and setting it inside the transfer barrel, the clogging speed of the filter plate by scale can be effectively slowed down, thereby extending the cleaning cycle of the filter plate. As a water-saving sprinkler irrigation machinery and equipment, it can further save water resources while reducing the water used for cleaning.

[0012] Preferably, the dirt scraping mechanism includes a shoveling plate, a mounting block, a rotating rod, a torsion spring and a baffle rod. The shoveling plate is arranged inside the transfer barrel, the mounting block is fixedly arranged on the corresponding connecting plate, the rotating rod is arranged at the end of the shoveling plate and passes through the mounting block, the torsion spring is sleeved on the rotating rod and its two ends are respectively connected to the mounting block and the rotating rod, and the baffle rod is arranged at the end of the rotating rod and in contact with the connecting plate.

[0013] It can be seen that to remove the scale attached to the inner wall of the transfer barrel, the conventional method is to use a high-pressure water gun for flushing. Considering that the entire equipment is set up in the wild and unattended for a long time, using a high-pressure water gun for flushing will not only waste a lot of water resources but also consume a lot of manpower costs, which does not meet the design requirements of water-saving sprinkler machinery and equipment. Therefore, this solution is adopted. The scale shoveling mechanism is set up to stir the water in the transfer barrel during the rotation of the driving rod. On the one hand, it can increase the turbulent effect of the water in the transfer barrel and evenly distribute the temperature of the water in the transfer barrel; on the other hand, it can guide the water so that the scale floating in the water enters the inside of the corresponding filter under the action of the shovel plate, so that the scale floating in the transfer barrel can be gradually collected, thereby preventing the scale from being pumped out of the outlet pipe into the soil during the random floating process, ensuring the normal growth of crops planted in the soil.

[0014] Preferably, a spring is sleeved on the connecting rod, and both ends of the spring are respectively connected to the connecting plate and the end of the connecting rod. When the spring is not deformed, the shovel plate is separated from the inner wall of the transfer barrel.

[0015] By adopting the above solution, when the driving rod rotates slowly and uniformly, the spring will not be deformed and can limit the position of the shovel plate, preventing the shovel plate from contacting the inner wall of the transfer barrel, thereby reducing the wear of the shovel plate on the inner wall of the transfer barrel. When the driving rod increases the speed under the drive of the motor, the centrifugal force generated during the rotation of the driving rod drives the shovel plate to the edge of the transfer barrel, so that the shovel plate contacts the inner wall of the transfer barrel, and the scale attached to the inner wall of the transfer barrel is removed during the continuous rotation of the driving rod. When the filter needs to be replaced, the inner wall of the transfer barrel is cleaned at the same time, thereby preventing the scale on the inner wall of the transfer barrel from affecting the heat conduction effect of the transfer barrel after long-term accumulation, thereby ensuring the water temperature irrigated to the soil and ensuring the normal growth of crops.

[0016] Preferably, the shovel plate is arranged in the transfer barrel and has an inclined surface on one side close to the edge of the transfer barrel, and the inclined surface is arranged toward the direction of rotation of the driving rod.

[0017] By adopting the above solution, when the driving rod rotates slowly and uniformly, the water and scale that pass through the gap between the shovel plate and the inner wall of the transfer barrel will quickly spread on the surface of the next shovel plate, so that they can enter the interior of the corresponding filter under the guidance of the shovel plate, slowing down the wear of the shovel plate on the inner wall of the transfer barrel, and improving the collection effect of scale, further avoiding the scale being pumped into the soil and affecting the normal growth of crops.

[0018] Preferably, the shovel plate is inclined toward the rotation direction of the driving rod and is provided with a guide groove extending to the inclined surface, and one end of the guide groove close to the axis of the transfer barrel is lower than the other end close to the edge of the transfer barrel.

[0019] By adopting the above solution, when the driving rod rotates clockwise in the top-down direction under the drive of the motor, the guide groove can guide the scale floating in the transfer barrel from top to bottom, and make the scale eventually enter the interior of the corresponding filter along the direction of the guide groove, so that it can be filtered by the filter, so that the scale remains in the filter, reducing the blockage of the filter plate by the scale and ensuring the normal water outlet effect of the outlet pipe, thereby ensuring the normal progress of the irrigation operation.

[0020] Preferably, a blocking groove is provided at the top of the guide groove, and a flange is provided at the top of the shovel plate and on the side facing the rotation direction of the driving rod.

[0021] By adopting the above scheme, the scale scraped off by the shovel can be blocked by the blocking groove after entering the interior of the guide groove, reducing the dispersion of scale inside the transfer barrel, and allowing the scale to enter the corresponding filter under the guidance of the blocking groove and the guide groove, so as to effectively filter the scale and reduce the scale flushed out during agricultural irrigation, thereby ensuring the normal growth of crops.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Through the photovoltaic panels, heat collecting mechanisms and gathering mechanisms, the water pumped into the transfer barrel can be doubly heated in conjunction with the heat collecting mechanism when the photovoltaic panels perform photoelectric conversion. The gathering mechanism can also be used to stir the water in the transfer barrel during the heating process, thereby achieving uniform heating of the water in the transfer barrel. At the same time, the filter in the gathering mechanism can be used to filter and collect scale precipitated from long-term heating, thereby preventing the water temperature from being too low and affecting the normal growth of crops. At the same time, the scale can be prevented from being pumped into the soil, thereby providing a double guarantee for the normal growth of crops.

[0024] 2. By setting the shovel plate, block and baffle, the block can be used to block the connecting plate during the continuous rotation of the driving rod driven by the motor, so as to prevent the increase of scale filtered in the filter and the close proximity of the two connecting plates, so that the filter can always maintain an "open" state. At the same time, the connecting plate can be used to block the baffle during the rotation of the driving rod, so that the shovel plate and the inner wall of the transfer barrel are in a separated state, so that the water and scale at the edge of the transfer barrel are diffused after passing through the gap between the shovel plate and the transfer barrel, and then the scale is collected and filtered by another filter, reducing the wear of the shovel plate and the inner wall of the transfer barrel, and preventing scale from accumulating at the edge of the transfer barrel, and preventing the scale from being pumped into the soil by the outlet pipe and affecting the normal growth of crops.

[0025] 3. By setting the rotating rod and torsion spring, when the output power of the motor increases and the centrifugal force generated when the driving rod rotates drives the edge of the shovel plate to contact, the shovel plate can rotate with the axis of the rotating rod as the rotation axis and energize the torsion spring, so that the edge of the shovel plate can always be close to the inner wall of the transfer barrel during the rotation of the driving rod, and the angle between the inclined surface opened on the shovel plate and the inner wall of the transfer barrel is increased, so that the shovel plate and the inclined surface on the shovel plate can be used to remove the scale attached to the inner wall of the transfer barrel during the continuous rotation of the driving rod. The removed scale can be guided and blocked by the guide groove, guide groove and flange on the shovel plate from top to bottom and from the edge of the transfer barrel to the center position and enter the corresponding filter, thereby avoiding the thickness of the scale on the inner wall of the transfer barrel affecting the heating effect and also preventing the scale from being pumped into the soil by the outlet pipe, further ensuring the normal growth of early spring crops.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 9 The present invention provides a concentrated solar-thermal photovoltaic intelligent pumping station, and the technical solution is as follows:

[0038] For details, please refer to Figure 1 、 Figure 2 and Figure 3A concentrating and heat-collecting photovoltaic intelligent pumping station includes a photovoltaic panel 1 and a mounting plate 2. The photovoltaic panel 1 is arranged above the mounting plate 2 by a mounting method, and also includes a heat collecting mechanism 3, a transfer barrel 4, a gathering mechanism 5 and a dirt scraping mechanism 6. The heat collecting mechanism 3 is arranged on the mounting plate 2, and the transfer barrel 4 is arranged on the heat collecting mechanism 3. The photovoltaic panel 1 performs photoelectric conversion when illuminated and heats the inside of the transfer barrel 4 through the heat collecting mechanism 3; the heat collecting mechanism 3 includes a fixing frame 31, an outer barrel 32, a constant temperature spiral heating tube 33, a heat collecting plate 34, a water inlet pipe 35 and a water outlet pipe 36. The frame 31 is set on the mounting plate 2, the outer barrel 32 is set on the fixing frame 31, the transfer barrel 4 is detachably set inside the outer barrel 32, and the constant temperature spiral heating tube 33 is set between the transfer barrel 4 and the outer barrel 32. Pure water is filled between the transfer barrel 4 and the outer barrel 32 to avoid the constant temperature spiral heating tube 33 from "dry burning" while expanding the heating range with pure water. The heating temperature of the constant temperature spiral heating tube 33 is controllable to avoid the temperature of the irrigation water pumped out being too high and causing damage to the crops. The heat collecting plate 34 is set on the mounting plate 2 and coaxially arranged at the bottom of the outer barrel 32. The bottom of the outer barrel 32 is set to a convex arc surface, the top of the heat collecting plate 34 is set to a concave arc surface, the water inlet pipe 35 is set at the bottom of the transfer barrel 4, the inner wall of the transfer barrel 4 is fitted with a filter plate 41, the outlet pipe 36 is set on the side wall of the transfer barrel 4 and is located at the filter plate 41, the water inlet pipe 35 and the outlet pipe 36 are both set through the outer barrel 32; the water inlet pipe 35 is movably connected to the bottom of the transfer barrel 4, and a sealing plate 351 is fixed on the water inlet pipe 35, which is fitted with the bottom of the transfer barrel 4. A sewage pipe 352 is supported on the water inlet pipe 35, and the top of the transfer barrel 4 A pickling pipe 43 is provided, and the water outlet pipe 36 is movably connected to the side wall of the transfer barrel 4 and is arranged above the water inlet pipe 35 to prevent the cold water that has just entered the transfer barrel 4 from being pumped out by the water outlet pipe 36. A second sealing plate 361 and a third sealing plate 362 are fixedly sleeved on the water outlet pipe 36. The second sealing plate 361 fits against the outer wall of the transfer barrel 4, and the third sealing plate 362 fits against the outer wall of the outer barrel 32 and is detachably connected to the outer barrel 32 to facilitate the disassembly and cleaning of the transfer barrel 4. At the same time, under the action of the filter plate 41, it can further prevent the water pumped into the soil by the water outlet pipe 36 from containing scale.

[0039] Under the above-mentioned setting conditions, after the sunlight hits the heat collecting plate 34, it will be reflected by the concave arc surface on the top of the heat collecting plate 34 and gathered at the bottom of the outer barrel 32. The outer wall of the outer barrel 32 is heated by light-to-heat conversion. At the same time, part of the electrical energy generated by the photovoltaic panel 1 during photoelectric conversion is used for storage, and the other part of the electrical energy is used to supply power to the constant temperature spiral heating tube 33, thereby heating the inner and outer sides of the outer barrel 32 at the same time, so that the pure water filled between the transfer barrel 4 and the outer barrel 32 is heated evenly, thereby ensuring the heating of the water in the rivers and lakes pumped into the transfer barrel 4, and avoiding the water in the transfer barrel 4 affecting the normal growth of early spring crops due to the low water temperature after being pumped into the soil.

[0040] As an embodiment of the present invention, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The gathering mechanism 5 is arranged on the heat collecting mechanism 3. When the gathering mechanism 5 is powered on and started, it rotates inside the transfer barrel 4 and collects the scale precipitated by heating inside the transfer barrel 4. The gathering mechanism 5 includes a mounting frame 51, a motor 52, a driving rod 53 and a gathering assembly 54. The mounting frame 51 is arranged on the transfer barrel 4. The motor 52 is arranged on the mounting frame 51 and the output end is connected to the driving rod 53. The inner circle of the filter plate 41 is provided with a connecting frame 42, and the connecting frame 42 is sleeved with the driving rod 53. Under the action of the connecting frame 42, the filter plate 41 is rotatably connected to the driving rod 53. The power generated by the water in the transfer barrel 4 during rotation can drive the filter plate 41 to rotate, thereby slowing down the clogging speed of the pipe mouth of the water outlet pipe 36. In order to extend the maintenance cycle of the entire device, the gathering component 54 is arranged inside the transfer barrel 4 and there are multiple circular arrays. The gathering component 54 includes two connecting rods 541, two connecting plates 542, a filter 543 and two blocks 544. The two connecting rods 541 are both arranged on the driving rod 53, and the two ends of each connecting plate 542 are respectively connected to the corresponding connecting rod 541, wherein the two ends of the connecting plate 542 near the edge of the transfer barrel 4 are respectively movably connected to the corresponding connecting rod 541, the filter 543 is arranged between the two connecting plates 542 and connected to the two connecting plates 542, the filter 543 is gauze, and the two blocks 544 are respectively fixed on the corresponding connecting rods 541.

[0041] Under the above-mentioned setting conditions, when the motor 52 is working, it can drive the driving rod 53 to rotate synchronously. Since the filter screen 543 is connected to the driving rod 53 in sequence through the connecting plate 542 and the connecting rod 541, the driving rod 53 can drive the filter screen 543 to rotate synchronously in the process of following the rotation of the output shaft of the motor 52. During the rotation process: on the one hand, the connecting plates 542 and the connecting plates 542 can stir the water in the transfer barrel 4, so that the heat generated by the heat collecting plate 34 and the constant temperature spiral heating tube 33 during heating can be evenly dispersed in the transfer barrel 4, ensuring that the water temperature in the transfer barrel 4 is evenly distributed, avoiding a large temperature difference in the water pumped out from the outlet pipe 36 and affecting the growth of crops; on the other hand, under the restriction of the block 544, the filter screen 543 can always maintain an "open" state, so that the filter screen 543 can filter the scale dispersed by the water in the process of rotation into the interior of the filter screen 543, thereby reducing the dispersion of scale and preventing the scale from being pumped into the soil by the outlet pipe 36, which can also ensure the normal growth of crops.

[0042] As an embodiment of the present invention, refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 The dirt scraping mechanism 6 is arranged on the gathering mechanism 5. When the load of the gathering mechanism 5 increases to a set value, it accelerates the rotation and drives the dirt scraping mechanism 6 to fit the inner wall of the transfer barrel 4. The dirt scraping mechanism 6 includes a shovel plate 61, a mounting block 62, a rotating rod 63, a torsion spring 64 and a baffle 65. The shovel plate 61 is arranged inside the transfer barrel 4, and the mounting block 62 is fixedly arranged on the corresponding connecting plate 542. The rotating rod 63 is arranged at the end of the shovel plate 61 and passes through the mounting block 62. The torsion spring 64 is sleeved on the rotating rod 63 and its two ends are respectively connected to the mounting block 62 and the rotating rod 63. The baffle 65 is arranged at the end of the rotating rod 63 and contacts the connecting plate 542. The set value can be measured in real time by installing a torque sensor on the output shaft of the motor 52, and the external device The control center controls the output power of the motor 52. When the amount of scale gathered by the gathering component 54 increases and the normal rotation of the driving rod 53 is affected (that is, the filtering effect of the gathering component 54 is affected), the external control center increases the output power of the motor 52, so that the output shaft of the motor 52 drives the driving rod 53 to rotate faster, so that under the action of centrifugal force, the shovel plate 61 expands outward to fit the inner wall of the transfer barrel 4. This is a conventional means in the prior art, so it is not described in detail; a spring 5411 is provided on the connecting rod 541, and the two ends of the spring 5411 are respectively connected to the connecting plate 542 and the end of the connecting rod 541. When the spring 5411 is not deformed, the shovel plate 61 is separated from the inner wall of the transfer barrel 4.

[0043] Under the above setting conditions, when the output power of the motor 52 does not increase, the spring 5411 squeezes the corresponding connecting plate 542 through its own elastic force, and blocks the connecting plate 542 through the action of the blocking rod 65 and the block 544, so that the edge of the shovel plate 61 does not contact the inner wall of the transfer barrel 4. In the process of stirring the water in the transfer barrel 4, the driving rod 53 will first gather and then diffuse when passing through the gap between the shovel plate 61 and the transfer barrel 4. The diffusion can increase the turbulence effect in the transfer barrel 4, on the one hand, accelerating the diffusion of water temperature, and on the other hand, allowing the scale to diffuse and enter the corresponding filter screen 543 for filtration under the action of the next shovel plate 61; when the output power of the motor 52 increases to drive the driving rod 53 to rotate faster, the centrifugal force generated during the rotation of the driving rod 53 will drive the connecting plate 542 movably sleeved with the connecting rod 541 to move toward the edge position of the transfer barrel 4. When the shovel plate 61 contacts the inner part of the transfer barrel 4, the movement path of the shovel plate 61 is blocked. At this time, under the action of the rotating rod 63, the rotating rod 63 can rotate around the axis of the rotating rod 63 as the rotation axis and energize the torsion spring 64 sleeved on the rotating rod 63, so that the edge of the shovel plate 61 can be close to the inner wall of the transfer barrel 4. Then, during the continuous rotation of the driving rod 53, the shovel plate 61 is used to scrape off the scale precipitated and attached to the inner wall of the transfer barrel 4 due to long-term heating, so as to prevent the transfer barrel 4 from affecting the heat conduction effect of the transfer barrel 4 due to the accumulation of scale on the inner wall, and the scale scraped off on the inner wall of the transfer barrel 4 can be further collected by the filter 543 during the continuous rotation of the driving rod 53.

[0044] As an embodiment of the present invention, refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 7 The shovel plate 61 is arranged in the transfer barrel 4 and has an inclined surface 611 on the side close to the edge of the transfer barrel 4, and the inclined surface 611 is arranged in the direction of rotation of the driving rod 53; the shovel plate 61 is inclined on the side facing the rotation direction of the driving rod 53 and has a guide groove 612 extending to the inclined surface 611, and the end of the guide groove 612 close to the axis of the transfer barrel 4 is lower than the end close to the edge of the transfer barrel 4; the top of the guide groove 612 is provided with a blocking groove 613, and the top of the shovel plate 61 and the side facing the rotation direction of the driving rod 53 is provided with a flange 614.

[0045] Under the above-mentioned setting conditions, when the edge of the shovel plate 61 does not fit the inner wall of the transfer barrel 4, the shovel plate 61 can expand the stirring range of the water in the transfer barrel 4 in the process of following the rotation of the driving rod 53 through the connecting plate 542 and the connecting rod 541, and at the same time can use the guide groove 612 to guide the scale floating in the water during the stirring process, so that the scale moves from top to bottom and finally enters the interior of the corresponding filter 543. When the edge of the shovel plate 61 contacts the inner wall of the transfer barrel 4, the shovel plate 61 will effectively remove the scale on the inner wall of the transfer barrel 4 under the action of the inclined surface 611 at the edge, and further guide the floating scale under the action of the guide groove 612, the blocking groove 613 and the flange 614, thereby achieving the cleaning of the inner wall of the transfer barrel 4 while filtering the cleaned scale again, and further preventing the scale from being pumped into the soil by the outlet pipe 36.

[0046] Working principle:

[0047] The present invention Figures 1 to 9 The various structures in the figure are for the purpose of ensuring the aesthetics of the drawings rather than the actual size. When working, the photovoltaic panel 1 generates electrical energy through photoelectric conversion, which controls the water inlet pipe 35 and the water outlet pipe 36 respectively, so that the water inlet pipe 35 pumps water from rivers and lakes into the transfer barrel 4, and the water outlet pipe 36 pumps the water in the transfer barrel 4 into the soil for planting early spring crops. On the other hand, the constant temperature spiral heating tube 33 is started to perform electrical heating between the transfer barrel 4 and the outer barrel 32, and at the same time cooperates with the heat collecting plate 34 to heat the bottom of the outer barrel 32 with the sunlight reflected and concentrated at the bottom of the outer barrel 32, so as to achieve the effect of heating the water in the transfer barrel 4, thereby avoiding the normal growth of early spring crops in winter and spring due to the low water temperature of irrigation water. Moreover, since the height of the water outlet pipe 36 is higher than the water inlet pipe 35, when irrigation is not needed, the water level in the transfer barrel 4 is lower than the height of the water outlet pipe 36, and the water outlet pipe 36 stops pumping, so that more water remains in the transfer barrel 4. The water in the transfer barrel 4 is kept at a constant temperature by the heat collecting plate 34 and the constant temperature spiral heating tube 33. That is, when the water inlet pipe 35 pumps cold water into the transfer barrel 4, the water level in the transfer barrel 4 will immediately rise to a level higher than the height of the water outlet pipe 36. However, after the cold water enters the transfer barrel 4 from the water inlet pipe 35, it is located at the bottom of the transfer barrel 4. The water pumped out from the water outlet pipe 36 is still warm water. Irrigation can be carried out immediately without waiting for the heating process, and crop growth will not be affected by the low water temperature.

[0048] In the process of heating the water in the transfer barrel 4, the motor 52 is started. The motor 52 can be powered by the electrical energy converted by the photovoltaic panel 1. When the motor 52 is working, it drives the driving rod 53 to rotate. When the driving rod 53 rotates, it drives the connecting rod 541 provided thereon to rotate. During the rotation of the connecting rod 541, it drives the two connecting plates 542 provided thereon to rotate. When the two connecting plates 542 rotate, it drives the filter screen 543 provided thereon to rotate synchronously. During the rotation of the connecting rod 541 and the connecting plate 542, the water in the transfer barrel 4 is stirred. , thereby accelerating the diffusion of water temperature and avoiding uneven water temperature in the water pumped out from the water outlet pipe 36. Since the connecting plate 542 is provided with a mounting block 62, and the mounting block 62 is connected to the shovel plate 61 via the rotating rod 63, the shovel plate 61 will also rotate synchronously with the driving rod 53. During the rotation process, the shovel plate 61 will not contact the inner wall of the transfer barrel 4 under the action of the blocking rod 65 provided on the rotating rod 63, thereby expanding the stirring range and accelerating the diffusion speed of the water temperature in the transfer barrel 4, thereby ensuring the normal growth of early spring crops in winter and spring.

[0049] When the water in the transfer barrel 4 flows, the scale precipitated by the long-term heating inside the transfer barrel 4 will float in the water, and under the action of the shovel plate 61 and the guide groove 612 opened on the shovel plate 61, the scale will follow the water flow from top to bottom and move from the edge of the transfer barrel 4 to the center of the transfer barrel 4. Since the filter screen 543 is in a state of following the rotation of the driving rod 53, the scale will follow the water flow into the corresponding filter screen 543. When the water passes through the filter screen 543, the scale will remain inside the filter screen 543, thereby reducing the dispersion of scale in the transfer barrel 4 and preventing the scale from being pumped into the soil by the outlet pipe 36. Since the driving rod 53 continues to rotate, when the amount of scale filtered out of the filter screen 543 increases, resulting in an increase in the load of the motor 52 (in this process, the filtering effect of the filter screen 543 decreases and the dispersion of scale is aggravated), the external control center sends a control signal to increase the output power of the motor 52, so that the driving rod 53 rotates faster. The centrifugal force generated during the accelerated rotation of the driving rod 53 increases. When the centrifugal force overcomes the elastic force of the spring 5411 and the torsion spring 64, the connecting plate 542 movably connected to the connecting rod 541 will move toward the edge of the transfer barrel 4, and in the process of movement, it can drive the shovel plate 61 to move synchronously toward the edge of the transfer barrel 4 through the mounting block 62 and the rotating rod 63. When the edge of the shovel plate 61 is in contact with the inner wall of the transfer barrel 4, the connecting plate 542 continues to approach the edge of the transfer barrel 4 under the action of centrifugal force. At this time, the movement of the shovel plate 61 is blocked and it will rotate with the axis of the rotating rod 63 as the rotation axis, thereby increasing the angle between the inclined surface 611 on the edge of the shovel plate 61 and the inner wall of the transfer barrel 4, thereby being able to shovel and collect scale attached to the inner wall of the transfer barrel 4 during the continuous rotation of the driving rod 53, thereby ensuring the heat conduction effect of the transfer barrel 4 while further ensuring the light-to-heat conversion efficiency when heating the irrigation water inside the transfer barrel 4, and preventing the scale in the transfer barrel 4 from being pumped into the soil, thereby ensuring the normal growth of crops;

[0050] Since the pump station is set up outdoors and is unattended for a long time, when the motor 52 drives the driving rod 53 to rotate at an accelerated speed, the water inlet pipe 35 and the water outlet pipe 36 are closed at the same time, and the pickling pipe 43 is automatically opened, and pickling liquid is added to the interior of the transfer barrel 4 through the pickling pipe 43. As the motor 52 continues to work, the pickling liquid mixes with the water in the transfer barrel 4 and can dissolve the scale in the transfer barrel 4. When the load of the motor 52 returns to the initial value, the drain pipe 352 is automatically opened to drain the water in the transfer barrel 4, thereby ensuring the subsequent normal use of the transfer barrel 4, and then ensuring the normal irrigation operation of the crops. Among them, the opening and closing of the pickling pipe 43, the water inlet pipe 35, the drain pipe 352 and the outlet pipe 36 can all be automatically controlled by existing technology.
