Description

Technical Field

[0001] This application relates to the field of soil and water conservation technology, and in particular to an environmentally friendly and ecological soil and water conservation device. Background Technology

[0002] Soil erosion refers to the loss of soil and water due to natural or human factors. Soil erosion is particularly severe along the Yellow River in my country. Soil and water conservation refers to the preventive and control measures taken against soil erosion caused by natural factors and human activities.

[0003] There are two main reasons for soil erosion along the slopes of the Yellow River. First, the loess layer on the slopes is eroded by rainwater when rainfall is excessive. Second, in areas with rapid currents, the high velocity of the river impacts the sediment along the banks, causing it to be carried away by the river. Summary of the Invention

[0004] In order to conserve soil and water, this application provides an environmentally friendly and ecological soil and water conservation device.

[0005] This application provides an environmentally friendly ecological soil and water conservation device, which adopts the following technical solution:

[0006] An environmentally friendly ecological soil and water conservation device includes a dam and a rainproof component; the dam is fixedly installed at the bottom of the slope; several sets of rainproof components are provided, and the rainproof components are installed on the slope and located at the top of the dam; the rainproof component includes a support cylinder, a bracket, and a rainproof cloth; the support cylinder is vertically installed on the slope; several brackets are arranged circumferentially along the support rod, and the brackets are connected to the support cylinder; the rainproof cloth is fixedly connected to the bracket, and the rainproof cloth is used to prevent rainwater from eroding the slope soil.

[0007] By adopting the above technical solutions, the embankment can protect the silt along the riverbank from river erosion. When rainfall is heavy, the rainproof cloth is placed on the slope, and the rainwater falls on the rainproof cloth, preventing the rainwater from falling directly onto the soil, thereby preventing the slope soil from being washed away by rainwater and playing a role in soil and water conservation.

[0008] Optionally, the dam has an arc-shaped structure in both the vertical and length directions; a number of flow-blocking blocks are fixedly installed on the side of the dam closest to the river, and the flow-blocking blocks have an arc-shaped structure on the side closest to the upstream of the river.

[0009] By adopting the above technical solution, when the river flow is large and the velocity is fast, the river water at the river edge is diverted by the dam during its flow, changing its flow direction and merging with the straight-flowing river water in the main channel, thus reducing the river's velocity. Simultaneously, the river water at the river edge is blocked by the flow-blocking blocks during its flow, changing its flow direction under the action of the flow-blocking blocks and convection with the straight-flowing river water in the main channel, further reducing the river's velocity and decreasing the erosion of sediment along the banks, thereby achieving the effect of soil and water conservation.

[0010] Optionally, the slope is planted with vegetation; the bracket is hinged to the support cylinder; a plurality of first adjustment components are provided on the slope, each of the first adjustment components corresponding to a rainproof component, and the first adjustment components are used to adjust the opening size of the rainproof cloth.

[0011] By adopting the above technical solutions, covering the slope with vegetation can prevent rainwater from falling directly onto the soil, thus preventing soil erosion. Simultaneously, the vegetation roots grow and take hold in the soil, contributing to soil and water conservation. During periods of heavy rainfall, the opening of the rainproof cloth is increased by the first adjustment component, allowing rainwater to fall onto the cloth instead of directly onto the soil and vegetation, further preventing soil erosion and conserving water and soil. In the early stages of vegetation growth, the vegetation is protected from erosion during the seedling stage. During periods of light rainfall, the opening of the rainproof cloth is decreased by the first adjustment component, allowing the vegetation to fully absorb sunlight, promoting growth, and thus contributing to soil and water conservation through vegetation.

[0012] Optionally, the first adjusting component includes a slider, a connecting rod, and a spring; the slider is located at the top of the hinge joint between the support cylinder and the bracket, the slider is slidably connected to the support cylinder, and the sliding axis is vertically arranged; a plurality of connecting rods are provided, each corresponding to one of the brackets, one end of each connecting rod is hinged to the slider, and the other end is hinged to the bracket; the spring is vertically arranged, and both ends of the spring are fixedly connected to the slider and the support cylinder, respectively.

[0013] By adopting the above technical solution, initially, the slider is located at the top of the support cylinder, and the opening of the rainproof cloth is relatively small. During rainfall, rainwater falls onto the rainproof cloth. When a certain amount of rainwater accumulates on the cloth, the cloth, under the influence of gravity, causes the support to rotate downwards. This, in turn, pulls the slider downwards via a connecting rod, increasing the opening of the rainproof cloth. At this time, the spring is compressed. When the rain stops, the slider slides upwards under the action of the spring, causing the support to rotate upwards around its hinge axis with the support cylinder via a connecting rod, decreasing the opening of the rainproof cloth. This allows for adjustment of the opening size of the rainproof cloth according to the rainfall conditions.

[0014] Optionally, the slope is provided with several sets of water storage components, each corresponding to one of the rainproof components. Each water storage component includes a water tank, a connecting pipe, an inlet pipe, and an outlet pipe. The water tank is fixedly installed on the slope. One end of the connecting pipe is connected to the inside of the water tank, and the other end is connected to a river. A one-way valve is installed on the connecting pipe to allow river water to enter the water tank through the connecting pipe. The inlet pipe is vertically installed at the top of the water tank and is equipped with a first valve. Several outlet pipes are provided and connected to the bottom of the water tank. A second valve is installed on each outlet pipe. Several irrigation components are provided on the slope, each corresponding to one of the outlet pipes, and are used to irrigate surrounding vegetation.

[0015] By adopting the above technical solution, after the operator completes the installation of the water storage component, they open the first valve and close the second valve, allowing water to be injected into the tank through the inlet pipe. Once the tank is full, the operator opens the second valve, causing the water to flow out through the outlet pipe, creating a negative pressure inside the tank. Under this negative pressure, river water enters the tank through the connecting pipe, forming a circulation. The water flowing out through the outlet pipe irrigates the surrounding vegetation through the irrigation components. By storing river water using a non-powered pumping structure and then irrigating the surrounding vegetation, the plant's root system is effectively utilized to conserve water and soil.

[0016] Optionally, the bottom of the support cylinder is an open structure and is connected to the water inlet pipe, and the bottom of the support cylinder is fixedly connected to the water inlet pipe; the bottom of the support cylinder is provided with a plurality of water leakage holes along its circumference; a flexible block is fixedly provided on the side of the bracket near the support cylinder, and the flexible block is used to isolate the water leakage holes from the external environment when the opening of the rainproof cloth is small.

[0017] By adopting the above technical solution, after the operator completes the installation of the water storage component, the first valve is opened and the second valve is closed. When there is rainfall, rainwater falls onto the rainproof cloth. When a certain amount of rainwater accumulates on the rainproof cloth, the opening of the rainproof cloth increases under the action of gravity. At the same time, the flexible block moves away from the drainage hole, and the rainwater enters the support cylinder from the drainage hole and then flows into the water storage tank. When the rain stops, after the rainwater on the rainproof cloth has flowed into the water storage tank, the slider slides upward under the action of the spring, the opening of the rainproof cloth decreases, and the flexible block covers the drainage hole, isolating the inside of the support cylinder from the outside. By collecting rainwater through the rainproof cloth when there is rainfall, the surrounding vegetation is irrigated through the irrigation component. This not only avoids rainwater directly eroding the soil but also utilizes rainwater to promote vegetation growth, achieving the effect of soil and water conservation.

[0018] Optionally, the irrigation assembly includes a first sprinkler pipe and a second sprinkler pipe; the first sprinkler pipe is vertically arranged and connected to the outlet pipe, and the first sprinkler pipe is fixedly connected to the slope; the second sprinkler pipe is horizontally arranged on top of the first sprinkler pipe, the second sprinkler pipe is connected to the first sprinkler pipe, the second sprinkler pipe is rotatably connected to the first sprinkler pipe, and the connection point is located at the middle of both ends in the length direction of the second sprinkler pipe; the second sprinkler pipe has a plurality of sprinkler holes, the sprinkler holes are divided into two groups, the two groups of sprinkler holes are respectively located on both sides of the first sprinkler pipe, and the two groups of sprinkler holes are respectively located on both sides of the second sprinkler pipe.

[0019] By adopting the above technical solution, water flowing from the outlet pipe flows through the first sprinkler pipe into the second sprinkler pipe, and then sprays out from the sprinkler holes. Driven by the water sprayed from the two sets of sprinkler holes, the second sprinkler pipe rotates around the axis of the first sprinkler pipe, irrigating the surrounding vegetation. The rotation of the second sprinkler pipe ensures uniform irrigation of the surrounding vegetation, making rational use of water resources, which is beneficial to vegetation growth and thus improves the effectiveness of soil and water conservation.

[0020] Optionally, the water storage tank is provided with several sets of second adjustment components, each corresponding to one of the irrigation components; the second adjustment component includes a float, a first telescopic rod, a second telescopic rod, and a connecting pipe; the float is disposed inside the water storage tank; the fixed end of the first telescopic rod is fixedly connected to the top of the water storage tank, and the movable end of the first telescopic rod is fixedly connected to the float; the movable end of the first telescopic rod divides the fixed end of the first telescopic rod into a first rod-side cavity and a first rodless cavity; the movable end of the second telescopic rod is inserted into the water outlet pipe, and the fixed end of the second telescopic rod is fixedly connected to the water outlet pipe. When the end face of the movable end of the second telescopic rod away from the fixed end of the second telescopic rod abuts against the side wall of the water outlet pipe, the two ends of the water outlet pipe are in an isolated state; the movable end of the second telescopic rod divides the fixed end of the second telescopic rod into a second rod-side cavity and a second rodless cavity; the two ends of the connecting pipe are respectively connected to the first rodless cavity and the second rodless cavity; water is pre-filled inside the connecting pipe, the first rodless cavity, and the second rodless cavity.

[0021] By adopting the above technical solution, when the rainfall is heavy, the water level in the water storage tank rises, the float floats higher, causing the first telescopic rod to retract, the first rodless chamber is squeezed into the second rodless chamber, the second telescopic rod extends, the distance between the end face of the movable end of the second telescopic rod away from the fixed end of the second telescopic rod and the side wall of the water outlet pipe decreases, the flow rate in the water outlet pipe decreases, and the amount of water sprayed from the sprinkler hole decreases.

[0022] When rainfall decreases, the water level in the storage tank drops, causing the float to float lower and the first telescopic rod to extend. This creates negative pressure in the first rodless chamber, drawing water from the second rodless chamber into the first rodless chamber. The second telescopic rod then contracts, increasing the distance between the movable end of the second telescopic rod (away from the fixed end) and the side wall of the outlet pipe. This increases the flow rate in the outlet pipe and the amount of water sprayed from the sprinkler holes. The amount of irrigation water provided to surrounding plants is adjusted according to rainfall levels. During the rainy season with heavy rainfall, less water is used to prevent waterlogging and inhibit plant growth. During the dry season with less rainfall, more water is used to provide sufficient moisture to vegetation, promoting growth and improving soil and water conservation.

[0023] Optionally, a filter screen is provided at the connection point between the connecting pipe and the river.

[0024] By adopting the above technical solution, a filter screen is installed to prevent silt and sand in the river from clogging the connecting pipe. At the same time, the river water can continuously flush the filter screen to prevent it from becoming clogged.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up dikes and flow-blocking blocks, dikes can protect riverbank sediment from river erosion. When the river flow is large and the velocity is fast, the water at the river's edge is diverted by the dikes, changing its flow direction and merging with the straight-flowing water in the main channel, thus reducing the river's velocity. Simultaneously, the water at the river's edge is blocked by the flow-blocking blocks, which change its flow direction and create convection with the straight-flowing water in the main channel, further reducing the river's velocity and minimizing the erosion of riverbank sediment, thereby achieving the effect of soil and water conservation.

[0027] 2. By incorporating a rain-blocking component and a first adjustment component, when rainfall is heavy, the first adjustment component increases the opening of the rain-blocking cloth, allowing rainwater to fall onto the cloth and preventing it from directly hitting the soil and vegetation. This prevents soil erosion on the slope and contributes to soil and water conservation. It also protects vegetation during its early growth stages, preventing seedlings from being eroded by rain. When rainfall is light, the first adjustment component decreases the opening of the rain-blocking cloth, allowing the vegetation to fully absorb sunlight, promoting growth and further enhancing soil and water conservation.

[0028] 3. By setting up irrigation components and a second regulating component, rainwater is collected through a rainproof cloth when there is rainfall, and then irrigated through the irrigation components to promote vegetation growth, thereby achieving the effect of soil and water conservation through plant roots; the amount of irrigation water to the surrounding plants is adjusted according to the amount of rainfall. When the rainfall is heavy during the rainy season, the amount of irrigation water is smaller to prevent waterlogging from inhibiting plant growth, and when the rainfall is light during the dry season, the amount of irrigation water is larger to provide sufficient water to the vegetation during the dry season, which is conducive to vegetation growth, thereby improving the effect of soil and water conservation.

[0043] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0044] This application discloses an environmentally friendly ecological soil and water conservation device. (Refer to...) Figure 1 An environmentally friendly ecological soil and water conservation device includes a dam 2 and rainproof components 3. The slope 1 is covered with vegetation. The dam 2 is fixedly installed at the bottom of the slope 1, located in a fast-flowing section of the river. Several sets of rainproof components 3 are installed on the slope 1, located at the top of the dam 2. The rainproof components 3 are used to shield the slope 1 from rainwater, preventing rainwater from eroding the soil of the slope 1.

[0045] Embankment 2 protects the riverbank from erosion. During periods of heavy rainfall, vegetation prevents rainwater from directly hitting the soil, thus preventing erosion of the slope 1. Simultaneously, the vegetation's root system helps conserve water and soil. Rain shelter 3 blocks rainwater, preventing erosion of the slope 1.

[0046] Reference Figure 2 and Figure 3 The dam 2 has an arc-shaped structure in both the vertical and length directions; several flow-blocking blocks 21 are set on the dam 2, and the flow-blocking blocks 21 are staggered. The flow-blocking blocks 21 are fixedly connected to the side of the dam 2 closest to the river channel, and the side of the flow-blocking blocks 21 closest to the upstream of the river has an arc-shaped structure.

[0047] As the river flows along its edge, it encounters an arched embankment 2. The embankment 2 alters the river's direction, causing it to merge with the straight-flowing water in the main channel, thus reducing the river's velocity. Similarly, as the river flows along its edge, it encounters a flow-blocking block 21. This block alters the river's direction, causing convection with the straight-flowing water in the main channel, further reducing the river's velocity and minimizing erosion of the riverbanks caused by excessive flow.

[0048] Reference Figure 2 and Figure 4Several sets of water storage components 5 are installed on the slope 1, each corresponding to a rainproof component 3. Each water storage component 5 includes a water tank 51, a connecting pipe 52, an inlet pipe 53, and an outlet pipe 54. The water tank 51 is fixedly installed on the slope 1 and is vertically positioned. One end of the connecting pipe 52 is connected to the inside of the water tank 51, and the other end is placed in the river channel and connected to the bottom of the river. A one-way valve 521 is installed on the connecting pipe 52, allowing river water to enter the water tank 51 through it. A filter screen 522 is installed at the bottom end of the connecting pipe 52 to filter sediment. The inlet pipe 53 is vertically positioned on top of the water tank 51 and is connected to the inside of the water tank 51. A first valve 531 is installed on the inlet pipe 53. Several outlet pipes 54 are provided and connected to the bottom of the water tank 51. A second valve 541 is installed on the outlet pipe 54.

[0049] Reference Figure 2 and Figure 5 The rainproof assembly 3 includes a support cylinder 31, a bracket 32, and a rainproof cloth 33. The support cylinder 31 is vertically mounted on top of the water storage tank 51 and is fixedly connected to the water storage tank 51. The bottom of the support cylinder 31 is open, and the interior of the support cylinder 31 communicates with the interior of the water storage tank 51. Several drainage holes 311 are opened around the bottom of the support cylinder 31, and the drainage holes 311 communicate with the interior of the support cylinder 31. Several brackets 32 are arranged around the support rod. The brackets 32 are inclined, and the distance between the brackets 32 and the support cylinder 31 gradually increases in the vertical upward direction. The bottom end of the brackets 32 is hinged to the support cylinder 31, and the hinge point is located below the drainage holes 311, and the hinge axis is horizontal. The rainproof cloth 33 has a circular structure and is coaxially arranged with the support cylinder 31, located below the drain hole 311. The rainproof cloth 33 is inclined, and the distance between the rainproof cloth 33 and the support cylinder 31 gradually increases along the vertical upward direction. The bottom end of the rainproof cloth 33 is fixedly connected to the support cylinder 31. The rainproof cloth 33 is located below the bracket 32 ​​and is fixedly connected to the bracket 32. A flexible block 321 with a circular structure is fixedly arranged on the side of the bracket 32 ​​near the support cylinder 31. The flexible block 321 is located at the opening of the drain hole 311.

[0050] Reference Figure 4 and Figure 5The water storage tank 51 is equipped with several sets of first adjustment components 4, each corresponding to a rainproof component 3. Each first adjustment component 4 includes a slider 41, a connecting rod 42, and a spring 43. The slider 41 has a groove 411 through which it passes, and the slider 41 is fitted onto the support cylinder 31, positioned above the hinge point between the support cylinder 31 and the bracket 32. The slider 41 is slidably connected to the support cylinder 31, and its sliding axis is vertical. Several connecting rods 42 are evenly arranged along the axis of the support cylinder 31, each corresponding to a bracket 32. One end of each connecting rod 42 is hinged to the slider 41 with its hinge axis horizontal, and the other end is hinged to the bracket 32 ​​with its hinge axis horizontal. The spring 43 is fitted onto the support cylinder 31, and both ends of the spring 43 are fixedly connected to the slider 41 and the bottom of the support cylinder 31, respectively.

[0051] Initially, the first valve 531 is open, the second valve 541 is closed, the slider 41 is located at the top of the support cylinder 31, and the opening of the rainproof cloth 33 is small. At this time, the flexible block 321 covers the drain hole 311, isolating the inside of the support cylinder 31 from the outside. When there is rainfall, rainwater falls onto the rainproof cloth 33. When a certain amount of rainwater accumulates on the rainproof cloth 33, under the action of gravity, the bracket 32 ​​rotates downward around the hinge axis with the support cylinder 31. The connecting rod 42 pulls the slider 41 downward, the spring 43 is compressed, and the opening of the rainproof cloth 33 increases. At this time, the flexible block 321 moves away from the drain hole 311, and the rainwater enters the inside of the support cylinder 31 from the drain hole 311, and then flows into the water storage tank 51. After the rain stops, once the rainwater on the rainproof cloth 33 flows into the water storage tank 51, the slider 41 slides upward under the action of the spring 43, and drives the bracket 32 ​​to rotate upward around the hinge axis with the support cylinder 31 through the connecting rod 42, thus reducing the opening of the rainproof cloth 33.

[0052] When the water storage tank 51 is filled with rainwater, the operator opens the second valve 541, and the water in the water storage tank 51 flows out from the outlet pipe 54, creating a negative pressure inside the water storage tank 51. Under the action of the negative pressure inside the water storage tank 51, the river water enters the water storage tank 51 through the connecting pipe 52, forming a circulation.

[0053] Reference Figure 4 and Figure 6Several irrigation components 6 are installed on the slope 1, each corresponding to a water outlet pipe 54, and are positioned among the vegetation. Each irrigation component 6 includes a first sprinkler pipe 61 and a second sprinkler pipe 62. The first sprinkler pipe 61 is vertically installed, with its bottom end connected to the water outlet pipe 54, and is fixedly connected to the slope 1. The second sprinkler pipe 62 is horizontally installed above the first sprinkler pipe 61, and is rotatably connected to it, with the axis of rotation being the axis of the first sprinkler pipe 61. The connection point between the second sprinkler pipe 62 and the first sprinkler pipe 61 is located at the midpoint between the two ends of the second sprinkler pipe 62's length. Several sprinkler holes 621 are provided on the second sprinkler pipe 62, divided into two groups. These two groups of sprinkler holes 621 are located at both ends and sides of the second sprinkler pipe 62's length.

[0054] Reference Figure 4 and Figure 6 A second adjusting assembly 7 is provided on the water storage tank 51; the second adjusting assembly 7 includes a float 71, a first telescopic rod 72, a second telescopic rod 73, and a connecting pipe 74. The float 71 is disposed inside the water storage tank 51. The first telescopic rod 72 is vertically disposed inside the water storage tank 51, with its fixed end fixedly connected to the top wall of the water storage tank 51 and its movable end fixedly connected to the float 71. The movable end of the first telescopic rod 72 divides its fixed end into a first rod-side cavity 721 and a first rodless cavity 722, with the first rod-side cavity 721 located below the first rodless cavity 722.

[0055] The second telescopic rod 73 is vertically installed outside the water storage tank 51. The fixed end of the second telescopic rod 73 is fixedly connected to the outer wall of the water storage tank 51, and also fixedly connected to the outer wall of the outlet pipe 54. The movable end of the second telescopic rod 73 is inserted into the outlet pipe 54. When the end face of the movable end of the second telescopic rod 73 away from the fixed end abuts against the side wall of the outlet pipe 54, the two ends of the outlet pipe 54 are isolated, and a distance is always maintained between the end face of the movable end of the second telescopic rod 73 away from the fixed end and the side wall of the outlet pipe 54. The movable end of the second telescopic rod 73 divides the fixed end of the second telescopic rod 73 into a second rod-containing cavity 731 and a second rodless cavity 732. The second rod-containing cavity 731 is located below the second rodless cavity 732. The two ends of the connecting pipe 74 are respectively connected to the first rodless cavity 722 and the second rodless cavity 732. Water is pre-filled inside the connecting pipe 74, the first rodless cavity 722, and the second rodless cavity 732.

[0056] Water flowing from the outlet pipe 54 flows into the second sprinkler pipe 62 through the first sprinkler pipe 61, and then sprays out from the sprinkler hole 621. Driven by the water sprayed from the two sets of sprinkler holes 621, the second sprinkler pipe 62 rotates around the axis of the first sprinkler pipe 61 to irrigate the surrounding vegetation.

[0057] During the rainy season, when rainfall is heavy, river flow is high and water levels are high, resulting in a greater supply of water to the water storage tank 51. Simultaneously, the rain cover 33 collects more rainwater, leading to a higher water level in the water storage tank 51. The float 71 floats on the surface of the water in the tank. The greater the rainfall, the higher the water level in the tank, resulting in a longer retracted length of the first telescopic rod 72. This causes more water to be squeezed from the first rodless chamber 722 into the second rodless chamber 732, further extending the second telescopic rod 73. Consequently, the distance between the movable end of the second telescopic rod 73 (away from the fixed end) and the side wall of the outlet pipe 54 is smaller, resulting in a lower flow rate in the outlet pipe 54 and less water sprayed from the sprinkler hole 621.

[0058] When rainfall decreases, river flow is low, water level is low, and less water is supplied to the water storage tank 51. Simultaneously, the rain cover 33 collects less rainwater, resulting in a lower water level in the water storage tank 51 and a lower floating height for the float 71. This causes the movable end of the first telescopic rod 72 to slide downwards, creating a negative pressure in the first rodless cavity 722. Under this negative pressure, water enters the first rodless cavity 722 from the second rodless cavity 732. The movable end of the second telescopic rod 73 slides upwards, increasing the distance between the end face of the movable end of the second telescopic rod 73 away from the fixed end and the side wall of the outlet pipe 54. This increases the flow rate in the outlet pipe 54, resulting in more water being sprayed from the sprinkler hole 621.

[0059] The implementation principle of an environmental protection and ecological soil and water conservation device according to an embodiment of this application is as follows:

[0060] Embankment 2 protects the riverbank from erosion. Vegetation prevents rainwater from falling directly onto the soil, thus preventing the soil on slope 1 from being washed away by rainwater. At the same time, the root system of the vegetation helps to conserve water and soil.

[0061] When the river has a large flow and a fast velocity, the water at the river's edge changes its flow direction under the action of the arc-shaped dam 2, merging with the straight-flowing water in the main channel, thus reducing the river's velocity. The water at the river's edge also changes its flow direction under the action of the flow-blocking block 21, creating convection with the straight-flowing water in the main channel, thereby reducing the river's velocity and minimizing the erosion of sediment along the banks caused by excessive river velocity.

[0062] Initially, the first valve 531 is open and the second valve 541 is closed, resulting in a small opening in the rainproof cloth 33. At this time, the flexible block 321 covers the drain hole 311, isolating the inside of the support cylinder 31 from the outside environment. During rainfall, rainwater falls onto the rainproof cloth 33. When a certain amount of rainwater accumulates on the cloth, the opening of the cloth 33 increases under the influence of gravity. Simultaneously, the flexible block 321 moves away from the drain hole 311, allowing rainwater to enter the support cylinder 31 through the drain hole 311 and then flow into the water storage tank 51. After the rain stops, the opening of the rainproof cloth 33 decreases again via the first adjusting component 4, while the flexible block 321 covers the drain hole 311.

[0063] When the water storage tank 51 is filled with rainwater, the operator opens the second valve 541, and the water in the water storage tank 51 flows out from the outlet pipe 54, creating a negative pressure inside the water storage tank 51. Under the action of the negative pressure inside the water storage tank 51, the river water enters the water storage tank 51 through the connecting pipe 52, forming a circulation.

[0064] Water flowing from the outlet pipe 54 irrigates the surrounding vegetation through the irrigation component 6. During the rainy season, when rainfall is heavy and the water level in the storage tank 51 is high, the flow rate in the outlet pipe 54 is reduced by the second regulating component 7, thus reducing the amount of water irrigated by the irrigation component 6. Conversely, when rainfall is light and the water level in the storage tank 51 is low, the flow rate in the outlet pipe 54 is increased by the second regulating component 7, thus increasing the amount of water irrigated by the irrigation component 6.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
