Description

TECHNICAL FIELD

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

[0002] The photoelectric intelligent pumping station is an intelligent pumping station system powered by solar energy in the solar energy industry, which is specially designed for green energy scenarios. With the advantages of high energy efficiency and intelligent control, it utilizes photoelectric conversion and photothermal conversion to show significant value in agricultural irrigation, mountain water supply, ecological water replenishment and other fields.

[0003] In the agricultural irrigation operation, the photovoltaic panel tracks the sunlight in real time through the intelligent control device and performs photoelectric conversion to provide power energy for the intelligent pumping station. Agricultural irrigation is usually carried out in the field and in the dry season, and the photoelectric intelligent pumping station is widely applied as a water-saving sprinkler irrigation mechanical equipment. Since the irrigation water is usually directly pumped from the lake or river by the water pump, the water inlet of the water pump is prone to be blocked during the operation due to the presence of a large amount of weeds and other impurities in the river and lake, which causes the water pump to stop and affects the timely irrigation of crops in the dry season, thereby affecting the normal growth of crops. In view of the above problems, the existing technology has a good solution, which can crush the impurities in the water flow by setting an impurity crushing mechanism in the pipeline, thereby avoiding the impurities from causing the water pump to be blocked, ensuring the normal use of the photovoltaic intelligent pumping station, and realizing the timely irrigation of crops in the dry season, thereby ensuring the normal growth of crops in the dry season. However, there are still the following defects: In Yunnan, many photovoltaic pumping stations are used for irrigation of crops in the dry season. Since the dry season in Yunnan is mostly in winter and spring (November to the following May), the environmental temperature is low. When irrigating early spring-planted crops (such as spring wheat and spring potatoes), if the water temperature is too low, it will inhibit the germination of seeds and the growth of seedlings, prolong the growth cycle, and increase the risk of diseases and pests. Therefore, it is necessary to heat the irrigation water in the pumping station water tank to ensure the normal growth of early spring-planted crops. However, long-term heating treatment will reduce the solubility of calcium and magnesium ions in water, resulting in the precipitation of scale in the water tank. The precipitated scale will be irrigated with water flow to the soil and adhere to the surface of the crop root system, thereby forming a water-impermeable and air-impermeable barrier that hinders the root system from absorbing gas and water from the soil, which also affects the normal growth of crops.

[0004] Therefore, in order to solve the above problems, a light-concentrating and heat-collecting photovoltaic intelligent pumping station is proposed. SUMMARY

[0005] The application aims to provide a light-gathering and heat-collecting photovoltaic intelligent pump station, which solves the problem that the scale separated out by heating adheres to the crop root system and affects the normal growth of crops after being irrigated into the soil.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme.

[0009] By adopting the above scheme, part of the electric energy generated by the photovoltaic panel during photoelectric conversion can be used to heat the constant temperature spiral heating pipe, the heat collecting plate can collect sunlight under illumination conditions, the bottom of the outer barrel is heated during the process of photo-thermal conversion, the transfer barrel is heated twice, and the water can be heated before being pumped into the soil, so as to avoid that the low water temperature limits the normal growth of crops.

[0010] Preferably, the gathering mechanism comprises 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 with the driving rod, the inner ring of the filter plate is provided with a connecting frame, the connecting frame is sleeved with the driving rod, the gathering assembly is arranged inside the transfer barrel and there are a plurality of circumferential arrays, the gathering assembly comprises two connecting rods, two connecting plates, a filter screen and two stop blocks, the two connecting rods are both arranged on the driving rod, the two ends of each connecting plate are respectively sleeved with the corresponding connecting rod, the filter screen is arranged between and connected with the two connecting plates, the filter screen is gauze, and the two stop blocks are respectively fixedly arranged on the corresponding connecting rod.

[0011] By adopting the above scheme, the motor can drive the water in the transfer barrel to rotate through the driving rod and the filter screen when working, so that the heat generated by the heat collecting mechanism can be quickly and uniformly dispersed in the transfer barrel, effectively improving the light-heat conversion efficiency, and since the filter screen is in an open state, the water entering the filter screen will pass through the filter screen, while the water scale floating in the water will be filtered inside the filter screen, avoiding the situation that the water scale will be pumped into the soil through the water outlet pipe after the transfer barrel is heated for a long time, effectively ensuring the normal growth of crops; at the same time, by arranging the filter plate inside the transfer barrel through the connecting frame, the clogging speed of the filter plate by the water scale can be effectively slowed down, thereby prolonging the cleaning cycle of the filter plate, as a water-saving sprinkling irrigation mechanical equipment, it can further save water resources while reducing cleaning water.

[0012] Preferably, the scale scraping mechanism comprises a scraping plate, a mounting block, a rotating rod, a torsional spring and a stop rod, the scraping 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 scraping plate and penetrates through the mounting block, the torsional spring is sleeved on the rotating rod and the two ends are respectively connected with the mounting block and the rotating rod, and the stop rod is arranged at the end of the rotating rod and in contact with the connecting plate.

[0013] It can be known that, to remove the scale attached to the inner wall of the transfer barrel, the conventional way is to use a high-pressure water gun to flush. Considering that the whole equipment is arranged in the wild and is unattended for a long time, using a high-pressure water gun to flush will not only waste a lot of water resources but also consume a lot of labor cost, which does not meet the design requirements of the water-saving sprinkling irrigation mechanical equipment, so this scheme is adopted. By arranging the scale scraping mechanism, the water in the transfer barrel can be stirred during the rotation of the driving rod, on the one hand, the turbulent effect of the water in the transfer barrel can be increased, and the temperature of the water in the transfer barrel can be uniformly distributed; on the other hand, the water can be guided, so that the scale floating in the water can enter the inside of the corresponding filter screen under the action of the scraping plate, so that the scale floating in the transfer barrel can be gradually collected, thereby avoiding the situation that the scale is pumped out of the soil through the water outlet pipe in the process of floating around, ensuring the normal growth of crops planted in the soil.

[0014] Preferably, a spring is sleeved on the connecting rod, two ends of the spring are connected with the connecting plate and the end of the connecting rod respectively, and the spade plate is separated from the inner wall of the transfer bucket when the spring is not deformed.

[0015] By adopting the above scheme, when the driving rod rotates slowly and uniformly, the spring will not be deformed and the position of the spade plate can be limited, so as to avoid the contact between the spade plate and the inner wall of the transfer bucket, thereby reducing the abrasion of the spade plate to the inner wall of the transfer bucket. When the driving rod is driven by the motor to increase the rotating speed, the centrifugal force generated during the rotation of the driving rod drives the spade plate to the edge position of the transfer bucket, so that the spade plate is in contact with the inner wall of the transfer bucket, and the scale attached to the inner wall of the transfer bucket is removed during the continuous rotation of the driving rod. When the filter screen needs to be replaced, the inner wall of the transfer bucket is cleaned together, so as to avoid that the scale on the inner wall of the transfer bucket affects the heat conduction effect of the transfer bucket after a long time of accumulation, thereby ensuring the water temperature in the soil irrigated, and ensuring the normal growth of crops.

[0016] Preferably, the spade plate is provided with an inclined surface on the side close to the edge of the transfer bucket.

[0017] By adopting the above scheme, when the driving rod rotates slowly and uniformly, the water and scale passing through the gap between the spade plate and the inner wall of the transfer bucket can quickly spread on the surface of the next spade plate, so as to be guided by the spade plate to enter the inside of the corresponding filter screen, thereby slowing down the abrasion of the spade plate to the inner wall of the transfer bucket, improving the collection effect of the scale, and further avoiding that the scale is pumped into the soil to affect the normal growth of crops.

[0018] Preferably, the side of the spade plate towards the rotating direction of the driving rod is obliquely provided with a guide groove extending to the inclined surface, and the end of the guide groove close to the axis of the transfer bucket is lower than the end close to the edge of the transfer bucket.

[0019] By adopting the above scheme, during the clockwise rotation of the driving rod in the top view direction under the driving of the motor, the guide groove can guide the scale floating in the transfer bucket from top to bottom, and finally make the scale enter the inside of the corresponding filter screen along the direction of the guide groove, so as to be filtered by the filter screen, so that the scale remains in the filter screen, reduces the plugging of the filter plate by the scale, and ensures the normal water outlet effect of the water outlet pipe, thereby ensuring the normal irrigation operation.

[0020] Preferably, a blocking groove is formed in the top of the guide groove, and a flange is arranged on the top of the spade plate and on the side towards the rotating direction of the driving rod.

[0021] Through the above scheme, the water scale scraped by the scraper plate can be blocked by the blocking groove after entering the inside of the diversion groove, reducing the floating of the water scale in the inside of the transfer bucket, so that the water scale can enter the corresponding filter screen under the guidance of the blocking groove and the diversion groove, so as to effectively filter the water scale, reduce the water scale flushed out during agricultural irrigation, and thus ensure the normal growth of crops.

[0022] Compared with the prior art, the beneficial effects of the present application are:

[0023] 1. By setting the photovoltaic panel, heat collecting mechanism and gathering mechanism, the water pumped into the transfer bucket can be doubly heated by the heat collecting mechanism when the photovoltaic panel performs photoelectric conversion, and the water in the transfer bucket can be stirred by the gathering mechanism during the heating process, realizing uniform heating of the water in the transfer bucket while filtering and collecting the water scale precipitated after a long time of heating by the filter screen in the gathering mechanism, avoiding the influence of low water temperature on the normal growth of crops while also avoiding the pumping of water scale into the soil, thus providing double protection for the normal growth of crops.

[0024] 2. By setting the scraper plate, stop block and stop rod, the connecting plate can be blocked by the stop block during the continuous rotation of the drive rod driven by the motor, avoiding the increase of water scale filtered in the filter screen to cause the two connecting plates to approach, so that the filter screen can always maintain an "open" state, and the scraper plate can be in a separated state with the inner wall of the transfer bucket by the blocking of the connecting plate to the stop rod during the rotation of the drive rod, so that the water and water scale at the edge position in the inside of the transfer bucket are diffused after passing through the gap between the scraper plate and the transfer bucket, and then the water scale is collected and filtered by another filter screen, reducing the wear of the scraper plate and the inner wall of the transfer bucket while avoiding the accumulation of water scale at the edge position in the inside of the transfer bucket, avoiding the pumping of water scale into the soil by the water outlet pipe to affect the normal growth of crops.

[0025] 3. By setting the rotating rod and torsional spring, the edge of the scraper plate can be driven to rotate around the axis of the rotating rod and energize the torsional spring when the edge of the scraper plate is in contact with the centrifugal force generated by the increase of the output power of the motor during the rotation of the drive rod, so that the edge of the scraper plate can always adhere to the inner wall of the transfer bucket during the rotation of the drive rod, and the included angle between the inclined surface provided on the scraper plate and the inner wall of the transfer bucket is increased, so that the water scale adhering to the inner wall of the transfer bucket is scraped by the scraper plate and the inclined surface on the scraper plate during the continuous rotation of the drive rod, and the scraped water scale moves from top to bottom and from the edge to the center position of the transfer bucket under the guidance and blocking action of the diversion groove, guide groove and flange on the scraper plate and enters the corresponding filter screen, avoiding the influence of the thickness of the water scale on the inner wall of the transfer bucket on the heating effect while also avoiding the pumping of water scale into the soil by the water outlet pipe, further ensuring the normal growth of early spring crops.

[0039] Under the above setting conditions, after sunlight is irradiated to heat collection plate 34, it is reflected and gathered at the bottom of outer barrel 32 through the arc surface of inner concave on the top of heat collection plate 34, and the photoelectric conversion of photovoltaic board 1 is used to store part of electric energy and to supply energy to constant-temperature spiral heating pipe 33, so that the inside and outside of outer barrel 32 are heated at the same time, the pure water filled between transfer barrel 4 and outer barrel 32 is uniformly heated, and the water in river or lake pumped into transfer barrel 4 is heated, to avoid that the water in transfer barrel 4 affects the normal growth of early spring crops due to low temperature after being pumped into soil.

[0040] As an embodiment of the present application, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the gathering mechanism 5 is arranged on the heat collecting mechanism 3, and the gathering mechanism 5 rotates inside the transfer barrel 4 and collects the scale heated and separated inside the transfer barrel 4 when the gathering mechanism 5 is started by power supply. The gathering mechanism 5 comprises 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 of the motor 52 is connected with the driving rod 53. The inner ring 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 rotationally connected with the driving rod 53. The power generated by the water in the transfer barrel 4 when rotating can drive the filter plate 41 to rotate, thereby slowing down the clogging speed of the pipe orifice of the water outlet pipe 36, prolonging the maintenance period of the whole device, and the gathering assembly 54 is arranged inside the transfer barrel 4 and circumferentially arranged with multiple gathering assemblies 54. The gathering assembly 54 comprises two connecting rods 541, two connecting plates 542, a filter screen 543 and two stop blocks 544. The two connecting rods 541 are both arranged on the driving rod 53. The two ends of each connecting plate 542 are respectively sleeved with the corresponding connecting rod 541. Among them, the two ends of the connecting plate 542 close to the edge of the transfer barrel 4 are respectively movably sleeved with the corresponding connecting rod 541. The filter screen 543 is arranged between the two connecting plates 542 and connected with the two connecting plates 542. The filter screen 543 is gauze. The two stop blocks 544 are respectively fixedly arranged on the corresponding connecting rod 541.

[0041] Under the above setting conditions, the motor 52 can drive the driving rod 53 to rotate synchronously when the motor 52 works. Since the filter screen 543 is connected with the driving rod 53 through the connecting plate 542 and the connecting rod 541 in sequence, the driving rod 53 can drive the filter screen 543 to rotate synchronously in the process of following the output shaft of the motor 52. In the rotating process: on the one hand, the connecting plate 542 and the connecting plate 542 can stir the water in the transfer barrel 4, so that the heat generated when the heat collecting plate 34 and the constant temperature spiral heating pipe 33 are heated can be uniformly dispersed in the transfer barrel 4, ensuring that the water temperature in the transfer barrel 4 is uniformly dispersed, avoiding that the water pumped out from the water outlet pipe 36 has a large temperature difference and affecting the growth of crops; on the other hand, under the limitation of the stop block 544, the filter screen 543 can always keep the "open mouth" state, so that the filter screen 543 filters the scale scattered by the water in the process of rotating in the inside of the filter screen 543, thereby reducing the scattering of the scale and avoiding that the scale is pumped into the soil by the water outlet pipe 36, which can also ensure the normal growth of crops.

[0042] As an embodiment of the present application, referring to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 8 andFigure 9 The scale scraping mechanism 6 is arranged on the gathering mechanism 5, the load of the gathering mechanism 5 is accelerated to rotate and drive the scale scraping mechanism 6 to adhere to the inner wall of the transfer barrel 4 when the load reaches a set value, the scale scraping mechanism 6 comprises a scraping plate 61, a mounting block 62, a rotating rod 63, a torsional spring 64 and a blocking rod 65, the scraping plate 61 is arranged inside the transfer barrel 4, the mounting block 62 is fixedly arranged on the corresponding connecting plate 542, the rotating rod 63 is arranged at the end of the scraping plate 61 and penetrates through the mounting block 62, the torsional spring 64 is sleeved on the rotating rod 63 and the two ends thereof are connected with the mounting block 62 and the rotating rod 63 respectively, and the blocking rod 65 is arranged at the end of the rotating rod 63 and is in contact with 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 output power of the motor 52 is controlled by the external control center, when the scale amount gathered by the gathering assembly 54 increases and affects the normal rotation of the driving rod 53 (i.e. affects the filtering effect of the gathering assembly 54), the external control center increases the output power of the motor 52, the output shaft of the motor 52 drives the driving rod 53 to rotate at a high speed, so that the scraping plate 61 is expanded outward to adhere to the inner wall of the transfer barrel 4 under the action of centrifugal force, which is a conventional means of the prior art, so it is not described in detail; the spring 5411 is sleeved on the connecting rod 541, the two ends of the spring 5411 are connected with the connecting plate 542 and the end of the connecting rod 541 respectively, and the scraping plate 61 is separated from the inner wall of the transfer barrel 4 when the spring 5411 is not deformed.

[0043] Under the above setting condition, when the output power of the motor 52 does not increase, the spring 5411 presses the corresponding connecting plate 542 by its own elastic force, and blocks the connecting plate 542 through the action of the stop rod 65 and the stop block 544, so that the edge of the shovel plate 61 does not contact the inner wall of the transfer bucket 4. During the process of driving the rod 53 to stir the water in the transfer bucket 4, the water at the edge position of the transfer bucket 4 and the scattered water scale will first gather and then diffuse when passing through the gap between the shovel plate 61 and the transfer bucket 4, and the diffusion can increase the turbulent flow effect in the transfer bucket 4, on the one hand to accelerate the diffusion of water temperature, on the other hand to diffuse the water scale and enter the corresponding filter screen 543 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 connected with the connecting rod 541 to move to the edge position of the transfer bucket 4, and the movement of the connecting plate 542 can not only enlarge the "mouth" of the filter screen 543, but also drive the mounting block 62 to move synchronously to the edge position of the transfer bucket 4. Since the mounting block 62 is connected with the rotating rod 63, and the rotating rod 63 is connected with the shovel plate 61, the mounting block 62 can drive the shovel plate 61 to move synchronously through the rotating rod 63 during the movement, and when the edge of the shovel plate 61 contacts the inside of the transfer bucket 4, the movement path of the shovel plate 61 is blocked. At this time, under the action of the rotating rod 63, the shovel plate 61 can rotate around the axis of the rotating rod 63 as the rotation axis and energize the torsional spring 64 connected with the rotating rod 63, so that the edge of the shovel plate 61 can tightly contact the inner wall of the transfer bucket 4, and then in the process of continuous rotation of the driving rod 53, the water scale attached to the inner wall of the transfer bucket 4 for a long time can be scraped off by the shovel plate 61, which can not only avoid the influence of the water scale accumulated on the inner wall of the transfer bucket 4 on the heat conduction effect of the transfer bucket 4, but also further collect the water scale scraped off from the inner wall of the transfer bucket 4 by the filter screen 543 during the continuous rotation of the driving rod 53.

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

[0045] Under the above setting condition, when the edge of the shovel plate 61 is not in contact with the inner wall of the transfer bucket 4, the shovel plate 61 can expand the stirring range of the water in the transfer bucket 4 in the process of following the driving rod 53 to rotate through the connecting plate 542 and the connecting rod 541, and can guide the scale scattered in the water to move from top to bottom and finally enter the inside of the corresponding filter screen 543 in the stirring process; when the edge of the shovel plate 61 is in contact with the inner wall of the transfer bucket 4, the shovel plate 61 can effectively shovel the scale on the inner wall of the transfer bucket 4 under the action of the inclined surface 611 at the edge, and further guide the scattered scale under the action of the flow guide groove 612, the blocking groove 613 and the flange 614, so that the inner wall of the transfer bucket 4 is cleaned, and the cleaned scale is filtered again, and the scale pumped into the soil by the water outlet pipe 36 is further avoided.

[0046] Working principle:

[0047] The Figures 1 to 9 Each structure in the present application is not the actual size but for the beauty of the drawings. In operation, the electric energy generated by the photovoltaic panel 1 through photoelectric conversion controls the water inlet pipe 35 and the water outlet pipe 36 respectively, so that the water inlet pipe 35 pumps the water in the river or lake into the transfer bucket 4, and the water outlet pipe 36 pumps the water in the transfer bucket 4 into the soil where early spring crops are planted. On the other hand, the constant temperature spiral heating pipe 33 is started to perform electric heating between the transfer bucket 4 and the outer bucket 32, and the heat collecting plate 34 is used to heat the bottom of the outer bucket 32 by reflecting and concentrating the sunlight on the bottom of the outer bucket 32, so as to heat the water in the transfer bucket 4, thereby avoiding the influence of low water temperature on the normal growth of early spring crops in winter and spring. In addition, the height of the water outlet pipe 36 is higher than that of the water inlet pipe 35, so that when irrigation is not needed, the water level in the transfer bucket 4 is lower than the height of the water outlet pipe 36, the water outlet pipe 36 stops pumping work, and more water is left in the transfer bucket 4. In addition, the water in the transfer bucket 4 is kept at a constant temperature under the action of the heat collecting plate 34 and the constant temperature spiral heating pipe 33, that is, when the water inlet pipe 35 pumps cold water into the inside of the transfer bucket 4, the water level in the transfer bucket 4 will immediately rise to exceed the height of the water outlet pipe 36, but the water pumped out of the water outlet pipe 36 is still warm water, which can be used for irrigation immediately without waiting for the heating process and will not affect the growth of crops due to low water temperature.

[0048] During the process of heating the water in the transfer bucket 4, the motor 52 is started, which can be powered by the photoelectric conversion of the photovoltaic panel 1. When the motor 52 works, it drives the driving rod 53 to rotate. When the driving rod 53 rotates, it drives the connecting rod 541 arranged thereon to rotate. In the process of rotating the connecting rod 541, the two connecting plates 542 arranged thereon are driven to rotate. When the two connecting plates 542 rotate, the filter screen 543 arranged thereon is driven to rotate synchronously. In the process of rotating the connecting rod 541 and the connecting plate 542, the water in the transfer bucket 4 is stirred, so as to accelerate the diffusion of water temperature and avoid the situation that the water pumped out from the water outlet pipe 36 is not uniform in temperature. Since the connecting plate 542 is provided with the mounting block 62, and the mounting block 62 is connected with the shovel plate 61 through the rotating rod 63, the shovel plate 61 will also rotate synchronously with the driving rod 53, and in the process of rotating, it will not contact the inner wall of the transfer bucket 4 under the action of the stop rod 65 arranged on the rotating rod 63, so as to expand the stirring range and accelerate the diffusion speed of the water temperature in the transfer bucket 4, so as to ensure the normal growth of early spring crops in winter and spring.

[0049] When the water in the transfer tank 4 flows, the scale that precipitates from prolonged heating inside the transfer tank 4 will float in the water. Under the action of the shovel plate 61 and the guide groove 612 on the shovel plate 61, the scale will move from top to bottom and from the edge of the transfer tank 4 towards the center of the transfer tank 4 with the water flow. Since the filter screen 543 is in a state of rotating with the drive rod 53, the scale will enter the corresponding filter screen 543 with the water flow. After the water passes through the filter screen 543, the scale will remain inside the filter screen 543, thereby reducing the scale from floating in the transfer tank 4 and preventing the scale from being pumped into the soil by the water outlet pipe 36. As the drive rod 53 continues to rotate, when the amount of scale filtered out by the filter screen 543 increases, causing the load on the motor 52 to increase (during this process, the filtration effect of the filter screen 543 decreases and the scale floating will be aggravated), the external control center sends a control signal to increase the output power of the motor 52, causing the drive rod 53 to rotate faster. The centrifugal force generated during the accelerated rotation of the drive rod 53 increases. When the centrifugal force overcomes the elastic force of the spring 5411 and the torsion spring 64, the connecting plate 542, which is movably sleeved with the connecting rod 541, will move towards the edge of the transfer tank 4. During the movement, the shovel plate 61 can be driven to move synchronously towards the edge of the transfer tank 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 tank 4, the connecting plate 542 continues to approach the edge of the transfer tank 4 under the action of centrifugal force. At this time, the movement of the shovel plate 61 is blocked and it will rotate about the axis of the rotating rod 63, thereby increasing the angle between the inclined surface 611 opened on the edge of the shovel plate 61 and the inner wall of the transfer tank 4. In this way, the scale adhering to the inner wall of the transfer tank 4 can be removed and collected during the continuous rotation of the driving rod 53. While ensuring the heat conduction effect of the transfer tank 4, it further ensures the photothermal conversion efficiency when heating the irrigation water inside the transfer tank 4, and avoids the scale in the transfer tank 4 being pumped into the soil, thereby ensuring the normal growth of crops.

[0050] Since the pumping station is located outdoors and is unattended for a long time, when the motor 52 drives the drive rod 53 to accelerate, the inlet pipe 35 and the outlet pipe 36 are closed at the same time, and the pickling pipe 43 is automatically opened. Pickling solution is added to the interior of the transfer tank 4 through the pickling pipe 43. As the motor 52 continues to work, the pickling solution mixes with the water in the transfer tank 4, which can dissolve the scale in the transfer tank 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 tank 4, thereby ensuring the normal use of the transfer tank 4 and thus ensuring the normal irrigation of crops. The opening and closing of the pickling pipe 43, the inlet pipe 35, the drain pipe 352, and the outlet pipe 36 can all be automatically controlled by existing technology.

Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
