Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to an energy-saving greenhouse water-fertilizer integrated system suitable for gently sloping terrains. Background Art

[0002] At present, agricultural greenhouses are more and more widely used in agricultural planting. When the greenhouse is built on a gentle slope, the existing mountain greenhouses do not give full play to the advantages of the hillside terrain. For example, a Chinese utility model with patent number ZL202020261728.0 (authorization announcement number CN212406264U) "A Hilly Multi-span Greenhouse" includes several connected stepped sheds, and the height of each stepped shed is different. Several stepped sheds are distributed in a stepped ascending or descending manner. Each stepped shed includes several side-by-side columns, an arc-shaped roof connected to the upper end of the columns, and a cross bar connected between the columns. Adjacent stepped sheds share a group of columns, which is characterized in that a first connecting mechanism for fastening the columns and the cross bar is provided between the columns and the cross bar, and a second connecting mechanism for connecting adjacent stepped sheds and diverting water is provided between the upper parts of adjacent stepped sheds. Although the greenhouse can be built in a staggered manner on uneven terrain such as hills, and greenhouses of different heights can be built in a continuous manner to cover a large area; the second connecting mechanism also has a drainage and diversion function on the basis of staggered connection of adjacent greenhouses, which is easy to install and has a solid structure. However, it fails to make full use of rainwater to irrigate plants or improve the living environment of plants in the greenhouse. Therefore, in order to make full use of the water source brought by rainfall, a rain gutter structure for collecting rainwater for irrigation is often provided on the greenhouse, such as a Chinese utility model with application number CN202022356308.3 (authorization announcement number CN213718982U) "A water-saving irrigation greenhouse for agricultural technology promotion and planting" discloses a water-saving irrigation greenhouse for agricultural technology promotion and planting, including a rain gutter fixedly connected to the outer surface of the greenhouse body, the top of the rain gutter is connected to a sewage interception cover by a hinge, and the surface of the sewage interception cover is provided with a plurality of leakage holes, which can block debris from falling into the downpipe. However, this structure can only prevent debris from falling into the water pipe, but cannot automatically clean the debris on the sewage interception cover. As a result, debris easily accumulates on the sewage interception cover, and once the debris rots, it can easily clog the downpipe, requiring manual cleaning. At the same time, the above patent also fails to consider the difficulty of insufficient sunlight on the side of the hillside. Therefore, it is necessary to provide an energy-saving greenhouse water and fertilizer integrated system suitable for gently sloping terrain. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide an energy-saving greenhouse water-fertilizer integrated system suitable for gently sloping terrain, which directly utilizes the advantages of the terrain itself to irrigate plants in response to the above-mentioned existing technical status.

[0004] The second technical problem to be solved by the present invention is to provide an energy-saving greenhouse water-fertilizer integrated system that can automatically clean debris in rainwater gutters in response to the above-mentioned existing technical status.

[0006] The fourth technical problem to be solved by the present invention is to provide an energy-saving greenhouse water-fertilizer integrated system suitable for gently sloping terrain, which can make up for the problem of insufficient light in hilly areas in response to the above-mentioned existing technical status.

[0008] A greenhouse body, wherein the greenhouse body is parallel to the vertical direction of the gentle slope;

[0009] a water storage container, located upstream of the greenhouse body and buried inside the gentle slope, storing water for watering the roots of the cultivated plants;

[0010] The feature is that the greenhouse body includes a frame for enclosing plants, the frame includes a wall portion arranged parallel to the height direction of the gentle slope, the wall portion is a hollow structure and a rain gutter is provided on the top for collecting rainwater, wherein the bottom of the rain gutter is connected to the wall portion through a first downpipe, the wall portion is connected to the water storage container through a second downpipe, and the bottom of the water storage container or the wall portion is connected to the irrigation pipeline to transport water to the roots of the target plants for irrigation.

[0011] To address the second technical problem, namely, to prevent debris from clogging the rain gutter and / or the first downpipe, which are open at the top for collecting rainwater, preferably, at least one debris filter is provided at the connection between the rain gutter and the first downpipe and / or upstream of the connection. Each debris filter is driven by an actuator located outside the rain gutter to cause each debris filter to flip outward relative to the rain gutter, thereby pouring debris collected by each debris filter out of the rain gutter. This allows debris in the rain gutter, which is open at the top for collecting rainwater, to be promptly drained away, thereby better promoting the flow of rainwater into the water storage container through the rain gutter and the first downpipe.

[0012] Preferably, the actuator is a water storage cup, and correspondingly, the water storage cup is connected to the debris filter portion via a connecting rod, the connecting rod has a pin shaft, and the rain gutter has a hinge seat for the pin shaft to be hinged, the water storage cup is used to accumulate rainwater to apply torque to the debris filter portion at the other end of the pin shaft, thereby driving the debris filter portion to flip outward relative to the rain gutter, and an elastic member is provided in the hinge seat to ensure that the debris filter portion always has a tendency to flip inward into the rain gutter.

[0013] Preferably, the debris filtering portion includes a vertical filtering portion and a transverse filtering portion that are roughly L-shaped; the vertical filtering portion is used to filter debris flowing along the rain gutter to the first downpipe, and the transverse filtering portion can be used to hold part of the debris filtered by the vertical filtering portion, and the transverse filtering portion is arranged along the direction of the rain gutter and close to the rain gutter.

[0014] Preferably, a limiting member is further provided on the rain gutter, and when the elastic member drives the debris filter portion to flip inward into the rain gutter, the limiting member limits the debris filter portion, and correspondingly, the edge of the vertical filter portion has a limiting portion that can cooperate with the limiting member, and the limiting member is a "J"-shaped limiting hook with an opening facing downward, including a vertical portion directly connected to the rain gutter and a curved hook portion connected to the vertical portion, and a gap is left between the curved hook portion and the rain gutter for the limiting portion of the vertical filter portion to enter. When each debris filter portion is driven by an actuator located outside the rain gutter, the limiting portion of the vertical filter portion forces the curved hook portion to deform to disengage from the curved hook portion, so that it can flip outward relative to the rain gutter; and when each debris filter portion is flipped inward into the rain gutter under the action of the elastic member, the limiting portion of the vertical filter portion of each debris filter portion can enter the gap and be limited.

[0015] Preferably, the wall portion is divided into at least two independent sub-wall portions, and each sub-wall portion has its own corresponding rain gutter, first downpipe, second downpipe and irrigation pipeline.

[0016] To solve the third technical problem, preferably, the greenhouse body further has an electrical control system for controlling the temperature, lighting and irrigation inside the greenhouse system, and the electrical control system includes:

[0027] The temperature control pipeline is provided with a water spray port to spray the water in the temperature control pipeline into the air inside the greenhouse body; and

[0028] A dehumidifier is connected to the water storage container through a drainage pipeline.

[0030] Preferably, a light refraction plate is movably connected to the inner side of the wall portion, and the electric control system further comprises a ventilation fan provided through the wall portion, and the light refraction plate can shake when the ventilation fan causes air flow.

[0031] Compared with the prior art, the advantages of the present invention are: a hollow structure wall is set to enclose the greenhouse body. On the one hand, the wall is a water storage structure set in front of the water storage container, which can further expand the water storage capacity of the greenhouse system; on the other hand, the wall is filled with air and rainwater. Since the specific heat capacity of the above substances is large, it can have a certain insulation effect on the greenhouse, avoid sudden rise and fall of temperature in the greenhouse, and be beneficial to plant growth. At the same time, it also takes advantage of the high and low terrain of the gentle slope and uses the gravity potential energy to guide rainwater to the wall of the greenhouse body and the water storage container buried on the slope. Since the water storage container and the wall are filled with air and rainwater, the water storage capacity of the greenhouse system can be further expanded. The terrain of the upper part is higher than that of the roots of the target plants, so that the accumulated water has gravitational potential energy relative to the roots of the target plants, and can flow to the top of the roots of the target plants through the irrigation pipes, which can reduce the use of water pumps and save more energy; and the water storage container is buried underground, and the temperature of the accumulated water inside changes more slowly than the greenhouse body, which has the characteristics of warm in winter and cool in summer. Therefore, when the temperature in the greenhouse needs to be adjusted, the water in the water storage container can be used as cooling and heating water, and sprayed into the greenhouse to form water mist, thereby increasing / decreasing the temperature inside the greenhouse to further improve the growth conditions of the plants in the greenhouse.

[0042] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 10 The embodiment of the present invention is shown in FIG. 1 . The energy-saving greenhouse water-fertilizer integrated system for gently sloping terrain of this embodiment includes a greenhouse body 2 parallel to the gentle slope 10; a control system, which can intermittently detect the temperature and humidity in the greenhouse, or obtain weather, light and other information from the information network through temperature and humidity sensors and network modules installed inside the greenhouse body, as well as Figure 6 The pipes shown are used for drainage, irrigation, temperature control, etc., wherein a water storage container 1 is located upstream of the greenhouse body and buried inside a gentle slope. The water storage container 1 is at a higher elevation than the roots of the target plants, so that the water stored inside the water storage container 1 has a greater gravitational potential energy relative to the roots 91 of the plants 9. In this embodiment, the water storage container 1 is relatively flat and the bottom surface inside is inclined, so that rainwater can always be preferentially accumulated near the connection between the irrigation pipe 11 and the water storage container 1. The greenhouse body 2 is a frame that encloses the plants 9 and includes a wall 21 and a roof 22, arranged parallel to the gentle slope 10. The wall 21 is a hollow, transparent container made of plastic or glass. Its top is equipped with an open rain gutter 3 to collect rainwater. The bottom of the rain gutter 3 is connected to the wall 21 via a first downpipe 31. The wall 21 is connected to the water storage container 1 via a second downpipe 4 connected to the upper portion. The bottoms of the water storage container 1 and the wall 21 are each connected to an irrigation pipe 11. For ease of description, the irrigation pipe on the water storage container side is designated as 11b, and the irrigation pipe on the wall 21 side is designated as 11a. A solenoid valve is connected to the irrigation pipe 11b on the water storage container 1 side. When watering is required, the control system operates the solenoid valve to open, allowing water to flow freely to the roots 91 of the target plant 9. The irrigation pipe 11a connected to the wall 21 is also connected to a solenoid valve, and a float switch is located within the wall 21. When the water volume in the wall 21 exceeds a certain level, the float switch lifts and transmits an electrical signal to the control system. The control system then preferentially opens the solenoid valve in the irrigation pipe 11a on the wall 21 side during irrigation, allowing the water inside the wall 21 to irrigate the plants 9 first. When the water volume in the wall 21 falls below the threshold that triggers the float switch to lift, the system activates irrigation with the water in the water storage container 1. Due to the high specific heat capacity of water, this structure also enhances the system's thermal insulation capabilities.

[0044] Furthermore, due to the height difference of the gentle slope 10, the greenhouse body 2 is also inclined, and the first downpipe 31 is located at the lower end of the rain gutter 3. Therefore, if the wall portion 21 has only one inner cavity, the water accumulated therein cannot exceed the connection between the rain gutter 3 and the first downpipe 31. Excess water would overflow, resulting in significant volume waste. Therefore, the wall portion 21 is divided into multiple segments along the gentle slope, each segment of the wall portion 21 having a corresponding independent rain gutter 3 and first and second downpipes. In this embodiment, the wall portion 21 is divided into two substantially identical sub-wall portions, such as a first sub-wall portion 2111 and a second sub-wall portion 2121. The first sub-wall portion 2111 and the second sub-wall portion 2121 differ only in height, and the connected pipelines are substantially identical. The irrigation pipeline 11 forms a ring above the roots 91 of the plant 9, with multiple pipelines extending from the ring toward the center, each of which has a water inlet at the end. When the water flows out of the water supply port, it can penetrate into the soil near the roots and deliver the water to the root area 91 of the plant 9. In addition, an annular groove 81 with nutrients buried therein is provided between the plant roots 91 and the irrigation pipe 11. Figure 5 As shown, the annular groove 81 has a feeding port 811 extending out of the ground surface, and a plurality of small holes 812 are opened at the bottom, so that when the irrigation water penetrates into the plant roots 91, the nutrients in the annular groove 81 can be dissolved and transported to the vicinity of the plant roots 91 through the small holes 822.

[0045] Since rainwater may carry some debris such as leaves and petals into the first downpipe 31 when it flows into the first downpipe 31 and block the first downpipe 31, it is necessary to install a debris filter 7, such as a filter net, at the connection between the rain gutter 3 and the first downpipe 31 or at its upstream position. The debris filter 7 can reduce the probability of debris other than rainwater entering the first downpipe 31 and the water storage container 1. However, since the filter net is fixed, it needs to be manually cleaned after debris accumulates. Therefore, this embodiment provides a debris filter 7 that can automatically clean the internal debris, such as Figure 3 As shown, the rain gutter 3 has a bucket-shaped debris filter 7 with a plurality of small holes on its surface at the connection between the rain gutter 3 and the first downpipe 31. The debris filter 7 can be turned over outside the rain gutter 3 to pour out the debris accumulated inside.

[0046] Specifically, if Figure 4 、 Figure 9As shown, the debris filter 7 comprises a vertical filter portion 71a and a transverse filter portion 71b, which are combined in a roughly L-shaped arrangement. The vertical filter portion 71a is a mesh member that filters debris flowing from the gutter 3 toward the downpipe 2. The transverse filter portion 71b, also a mesh member, is used to partially contain debris filtered by the vertical filter portion 71a. The transverse filter portion 71b is positioned along and adjacent to the gutter 3, forming a roughly L-shaped arrangement. The debris filter 7 can be driven by an actuator located outside the gutter 3, which causes the debris filter 7 to flip outward relative to the gutter 3.

[0047] In this embodiment, the actuator is a water storage cup 74. Correspondingly, the water storage cup 74 is connected to the vertical filter portion 71a of the debris filter 7 via a generally strip-shaped connecting rod 72. The connecting rod 72 has a pin 73 extending transversely through the rod, roughly dividing the connecting rod 72 into two sections. The rain gutter 3 has an articulated seat 732 for the pin 73 to articulate. The water storage cup 74 accumulates rainwater, thereby applying a torque to the debris filter 7 at the other end of the pin 73, driving the debris filter 7 outward relative to the rain gutter 3. Within the articulated seat 732 is an elastic member 75, which can be a torsion spring, rubber band, or the like, that ensures that the debris filter 7 always tilts inward into the rain gutter 3. When the debris filter 7 tilts outward, accumulated debris can be poured out.

[0048] However, during rain, debris may become stuck to the debris filter 7 due to the action of rainwater. To further increase the acceleration of the debris filter 7 as it flips outward, thereby removing any debris collected therein, a limiter 76 is provided on the rain gutter 3. When the elastic member 75 drives the debris filter 7 to flip inward into the rain gutter 3, the limiter 76 limits the position of the debris filter 7. Accordingly, the edge of the vertical filter portion 71a of the debris filter 7 has a protrusion, forming a limiter 711 that engages with the limiter 76. Furthermore, a limiter 76 is provided on the rain gutter 3. When the elastic member 75 drives the debris filter 7 to flip inward into the rain gutter 3, the limiter 76 limits the position of the debris filter 7. Accordingly, the edge of the vertical filter portion 71a of the debris filter 7 has a protrusion, forming a limiter 711 that engages with the limiter 76. Since the potential energy provided by the elastic member 75 is smaller than the potential energy when the water storage cup is turned over by accumulated water, it is necessary to make it easier for the limiting portion 711 to buckle back to the limiting member 76 than to get rid of the limiting member 76. Therefore, the limiting member 76 is an inverted "J"-shaped limiting hook with an opening facing downward, which can be made of materials such as rubber, plastic or metal. It includes a vertical portion 761 directly connected to the rain gutter 3 and a hook portion 762 connected to the vertical portion 761. A gap 763 is left between the hook portion 762 and the rain gutter 3 for the limiting portion 711 of the vertical filter portion 71a to enter. When each debris filter portion 7 is driven by an actuator located outside the rain gutter 3, the limiting portion 711 of the vertical filter portion 71a forces the hook portion 762 to deform to disengage from the hook portion 762, so that it can flip outward relative to the rain gutter 3. At this time, the gravitational potential energy accumulated in the water storage cup 74 is released, causing the water storage cup 74 to flip over at an accelerated rate, and driving the debris filter portion 7 to flip over at the same angular velocity, thereby throwing out the debris accumulated therein.

[0049] Once the water in the water storage cup 74 is drained, the elastic member 75 drives the water storage cup 74 and the debris filter 7 to rotate. With each debris filter 7 flipped inward into the rain gutter 3 by the elastic member 75, the stopper 711 of the vertical filter portion 71a of each debris filter 7 causes the vertical portion 761 of the stopper 76 to deform laterally, entering the notch 763 and being retained. Because the force required to deform the hook portion 762 of the stopper 11 outward is greater than the force required to deform the vertical portion 761 laterally, the force required to engage the stopper 76 is less than the force required to disengage the stopper 76. Furthermore, since the debris filter 7 loses its ability to filter debris for a short period of time after being flipped out of the rain gutter 3, this embodiment provides two debris filters 7 and corresponding actuating, rotating, and limiting mechanisms within the rain gutter 3. These filters are located at the connection with the downpipe 2 within the rain gutter 3 and upstream of the connection with the downpipe 2. To ensure that at least one stage of the multi-stage debris filter 7 is in the filtering state, the opening size of the water storage cup 74 of each debris filter 7 can be adjusted to different specifications. Because the force required for the limiting portion 711 to free itself from the limiting member 76 when each debris filter 7 needs to flip is the same, the water volume required in the water storage cup is the same. Therefore, under the same rainfall conditions, the water storage cup with a larger opening requires less time to reach the target water volume. Therefore, the water storage cup with a larger opening flips more frequently, while the water storage cup with a smaller opening flips more slowly. Thus, in this embodiment, by setting the opening sizes of the water storage cups corresponding to the two debris filter portions 3 to different sizes, it is possible to ensure that at least one level of debris filter portion 3 is within the rain gutter 1 and is filtering at the same time. Similarly, similar effects can be achieved by adjusting the elastic coefficients of the limiting members corresponding to each level of debris filter portion 7 to adjust the rainwater volume required for each level of debris filter portion 7 to flip out of the rain gutter 3, or by adjusting the elastic coefficient of the elastic member 75 to adjust the time it takes for each level of debris filter portion 7 to flip back into the rain gutter 3.

[0050] Finally, in order to provide the energy required by the greenhouse system, the system also has an electrical control system electrically connected to the control system, such as Figure 1As shown, the structure includes a rectangular photovoltaic panel 5. When positioned above the greenhouse body, the panel 5 can block some incoming sunlight. The panel 5 is electrically connected to a battery to store the electricity converted by the panel. The structure also includes a bracket 52 located on the side of the greenhouse body. The bracket 52 consists of two support columns 521 and a motor 522. The support columns 521 are composed of two support columns standing on the ground and two swing arms 523 connected to the photovoltaic panel 5. One end of the swing arm 523 is driven to rotate by the motor 522 connected to the support column, while the other end of the swing arm 523 is connected to the photovoltaic panel 5. Driven by the motor 522, the swing arm 523 rotates the photovoltaic panel 5 to the side above or to the side of the greenhouse body 2. In this embodiment, two sets of photovoltaic panels 5 and brackets 52 are provided, located opposite each other on either side of the greenhouse body. When the temperature is too high, the photovoltaic panels 5 can rise above the side of the greenhouse body 2 to block some incoming sunlight.

[0051] In order to prevent the temperature in the greenhouse from being too high as much as possible, the system also has a water pump 61 located downstream of the water storage container and a temperature control pipe 62 located inside the greenhouse body 2. In this embodiment, the temperature control pipe 62 is basically at the same height as the rain gutter 3 and surrounds the inside of the greenhouse body 2. The temperature control pipe 62 has multiple water spray outlets 621 connected to the water pump 61, so that the water delivered by the water pump 61 can be sprayed into the air inside the greenhouse body 2 through the water spray outlets 621; in addition, a dehumidifier 22 powered by a battery is provided inside the greenhouse body 2. The dehumidifier 22 is connected to the water storage container 1 through a drainage pipe 221. The dehumidifier 22 can take away the heat in part of the water vapor in the greenhouse body 2 while also recycling the water vapor. Due to the limitations of the mountainous terrain, the gentle slope 10 may block part of the sunlight from entering the greenhouse body 2 in the morning or evening, and the photovoltaic panel 5 will also block part of the sunlight entering the greenhouse. For this reason, a plurality of prisms 51 are arranged on the back of the photovoltaic panel 5 with the side edges parallel to the direction of the photovoltaic panel. The prism 51 can refract the sunlight entering the prism 51 into the greenhouse when the photovoltaic panel 5 on one side is facing away from the sun. In addition, the control system of the greenhouse can query the incident angle of sunlight according to the date change, so that when the incident sunlight is blocked by the photovoltaic panel 5 on one side, the photovoltaic panel 5 on the other side can select the angle for refracting the sunlight into the greenhouse. Since the fruits of the plant 9 are often blocked by the branches and leaves above, some fruits develop slowly due to insufficient light. Therefore, if Figure 7 and 8As shown, four light strips 531 electrically connected to the energy storage system are arranged in the top cover 22 inside the greenhouse body 2, and a light glossy paper is formed into a concave mirror with multiple notches facing outward and can be adhered on the same plane to form a light refraction plate 53. In this embodiment, there are four light refraction plates 53 and they are suspended on the inner side of the wall 21 of the greenhouse body 2. Four ventilation fans 211 are arranged through the wall portion 21 of the greenhouse body. Each ventilation fan 211 is located on the back of the light refraction plate 53 and rotates at different speeds clockwise or counterclockwise to achieve a blowing or sucking effect. This can enhance the air circulation in the greenhouse. It can also be calculated and adjusted by the control system so that the light refraction plate 53 forms different angles relative to the wall portion 21 to correspond to the sunlight refracted into the greenhouse body 2 by the prism 51 behind the photovoltaic panel 5 or the light emitted by the light strip 531. In addition, the light refraction plate 53 may shake slightly when the air flows, thereby refracting the incident light to form a jittering light spot, which is irradiated from the side to the fruits of different parts of the target plant 9 to promote the development of the fruit.

[0052] In summary, the greenhouse system is controlled by a control system and utilizes the high and low terrain characteristics of the gentle slope 10. When it rains, the gravitational potential energy causes rainwater to flow from the outer surface of the greenhouse top 22 into the rain gutter 3. The rain gutter 3 has a slope similar to that of the gentle slope 10, and can guide the rainwater through the first downpipe 31 to the wall 21 of the greenhouse body 2 for storage. During this process, the debris filter 7 can reduce the risk of debris clogging the pipe. When the rainwater accumulates to a certain height in the wall 21, the excess rainwater flows into the water storage container 1 buried on the slope through the second downpipe 4. Since the water storage container 1 is at a higher altitude than the root 91 of the target plant 9, the accumulated water therein has gravitational potential energy relative to the root 91 of the target plant 9. When the system reaches the irrigation time preset by the control system or manual remote irrigation is performed, the solenoid valve of the irrigation pipeline 11 opens, so that the water accumulated in the wall 21 or the water storage container 1 can flow through the irrigation pipeline 11 to the root 91 of the target plant 9 for irrigation. Since water storage container 1 is buried underground, the temperature of the water inside changes more slowly than that of greenhouse body 2, resulting in a warm winter and cool summer environment. Therefore, when the control system needs to adjust the temperature inside the greenhouse, it can use water pump 61 to pump water from water storage container 1 and spray it into the greenhouse to form a mist, thereby increasing or decreasing the temperature inside the greenhouse. At the same time, the photovoltaic panels 5 store electrical energy to provide the power needed for system operation. The panels can also be opened and closed to provide shade and cooling. For example, in the summer, when the system receives a weather forecast or detects a need to cool the greenhouse through temperature / light intensity sensors, it can raise the photovoltaic panels 5, partially reducing the amount of light in the greenhouse and further lowering the temperature. The light strip 531 can use the solar energy converted by the photovoltaic panel for lighting. In addition, the system determines the direction of incident sunlight and operates the motor 522 on the photovoltaic panel 5 bracket 52 to turn the photovoltaic panel 5 so that the prism 51 behind it is aimed at the sunlight. A part of the sunlight can be added to the interior of the greenhouse body 2, and the light refraction plate 53 inside the greenhouse body 2 allows the incident light from the prism 51 and the light strip 531 to be refracted to multiple corners of the plant that are blocked by branches and leaves, thereby increasing the lighting effect and promoting the growth and ripening of the fruit.

Correspondingly, the water storage cup (74) and the debris filter (7) are connected via a connecting rod (72). The connecting rod (72) has a pin shaft (73), and the rain gutter (3) has a hinge seat (732) for hinged connection of the pin shaft (73). The water storage cup (74) is used to accumulate rainwater to apply a torque to the debris filter (7) at the other end of the pin shaft (73), thereby driving the debris filter (7) to flip outward relative to the rain gutter (3). An elastic member (75) is provided in the hinge seat (732) to ensure that the debris filter (7) always has a tendency to flip inward into the rain gutter (3). The debris filter portion (7) includes a vertical filter portion (71a) and a transverse filter portion (71b) that are roughly L-shaped. The vertical filter portion (71a) is used to filter debris flowing along the rain gutter (3) toward the first downpipe (31), while the transverse filter portion (71b) can be used to contain some of the debris filtered by the vertical filter portion (71a). The transverse filter portion (71b) is arranged along the direction of the rain gutter (3) and close to the rain gutter (3). The rain gutter (3) is also provided with a limiting member (76). When the elastic member (75) drives the debris filter (7) to flip inward into the rain gutter (3), the limiting member (76) limits the debris filter (7). Correspondingly, the edge of the vertical filter (71a) has a limiting portion (711) that can cooperate with the limiting member (76). The limiting member (76) is an inverted "J"-shaped limiting hook with an opening facing downward, comprising a vertical portion (761) directly connected to the rain gutter (3) and a curved hook portion (762) connected to the vertical portion (761). A space for the vertical filter (71a) to be opened is left between the curved hook portion (762) and the rain gutter (3). The limiting portion (711) of the vertical filter portion (71a) enters the notch (763). When each debris filter portion (7) is driven by an actuator located outside the rain gutter (3), the limiting portion (711) of the vertical filter portion (71a) forces the hook portion (762) to deform and disengage from the hook portion (762), thereby enabling the vertical filter portion (71a) to flip outward relative to the rain gutter (3). When each debris filter portion (7) is flipped inward into the rain gutter (3) under the action of the elastic member (75), the limiting portion (711) of the vertical filter portion (71a) of each debris filter portion (7) can enter the notch (763) and be limited.
