Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, and in particular to a rainwater collection and storage device for soil and water conservation. Background Technology

[0002] Soil and water conservation is a crucial aspect of ecological environmental protection and agricultural production. Effective collection and utilization of surface runoff rainwater is of great significance for alleviating water shortages and preventing soil erosion. Currently, most common rainwater harvesting devices employ static storage methods such as reservoirs and collection tanks. However, surface runoff typically carries a large amount of sediment, and direct collection leads to sediment accumulation in the storage containers, significantly reducing the effective storage capacity and impacting collection efficiency. Furthermore, cleaning and maintenance are difficult, and long-term use can easily cause blockages in pipes or outlets. While some existing technologies employ simple filtration structures, they often suffer from incomplete separation, clogging, and the need for manual intervention or additional power, making it difficult to achieve efficient, automated, and long-term stable sediment separation and rainwater harvesting. Utility Model Content

[0003] This utility model relates to a rainwater collection and storage device for soil and water conservation, which integrates rainwater collection and automatic sediment separation functions, and is a reliable and easy-to-maintain device.

[0004] In a first aspect, this utility model provides a rainwater collection and storage device for soil and water conservation, specifically comprising: a collection and storage base; rotating wheel seats fixedly installed at the top left and right ends of the collection and storage base; a drainage pipe rotatably installed between the two rotating wheel seats; and a hopper provided in the inner cavity of the collection and storage base at the downstream position of the drainage pipe, the upper end of the hopper being tangent to the outer wall of the drainage pipe.

[0005] Optionally, the bottom plate of the storage tank has a rectangular opening where it contacts the ground.

[0006] Optionally, the rotating wheel seat is provided with symmetrical pulleys, which are metal-bladed wheels.

[0007] Optionally, a spiral guide plate is fixedly installed in the inner cavity of the drain pipe, and ring rails are fixedly installed at the upstream and downstream ends of the drain pipe respectively. The ring rails are provided with wheel grooves that engage with the rotation of the pulleys, and the drain pipe rotates between two rotating wheel seats.

[0008] Optionally, the drain pipe has evenly spaced drainage holes on its wall corresponding to the position of the hopper, and a soil leakage hole with an enlarged diameter is also opened on the drain pipe on one side of the drainage hole.

[0009] Optionally, the lower end of the storage tank is a sloping structure that fits in contact with the ground, and the hopper is a structure that is wider at the top and narrower at the bottom.

[0010] This utility model provides a rainwater collection and storage device for soil and water conservation, which has the following beneficial effects: First, the core of the device lies in the rotatable drainage pipe and its internally fixed spiral guide plate. This design forces the silt-laden water flowing into the pipe to move in a spiral motion, automatically and efficiently throwing the heavier silt against the pipe wall using the generated centrifugal force, thus achieving physical separation of silt and water. The entire process requires no external power, making it energy-saving and efficient. Second, the separated clean water naturally seeps out through evenly spaced drainage holes on the pipe wall and flows back to the collection tank, while the accumulated silt is discharged through enlarged soil leakage holes and collected and guided away by precisely positioned discharge hoppers. The hoppers, wider at the top and narrower at the bottom, ensure smooth silt collection and prevent accumulation, thereby achieving water-soil separation at the source, effectively preventing siltation in the storage area, and ensuring a continuous and sufficient water storage capacity in the collection tank.

[0011] Furthermore, the drainage pipe is supported and rotated through the engagement of a ring rail with a metal-bladed pulley in the rotating wheel seat. This rotational motion not only provides the necessary conditions for centrifugal separation, but its dynamic process also has a self-cleaning effect, effectively preventing the drainage holes and soil leakage holes from being blocked by mud or debris, greatly improving the long-term reliability of the device. The design of the metal-bladed pulley further cuts through any debris that may become entangled during rotation, ensuring the smoothness and durability of the rotating mechanism. In addition, the inclined structure at the bottom of the collection tank and its exposed opening optimize the path of surface runoff, enhance the fit between the device and the ground, facilitate the rapid collection of rainwater, and also play a role in locally stabilizing the soil, demonstrating the dual function of soil and water conservation.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please refer to Figures 1 to 4 : Example 1: This utility model proposes a rainwater collection and storage device for soil and water conservation, including: a collection and storage bottom box 1; rotating wheel seats 2 are fixedly installed at the top left and right ends of the collection and storage bottom box 1 respectively; a drainage pipe 3 is rotatably installed between the two rotating wheel seats 2; a feeding hopper 4 is provided in the inner cavity of the collection and storage bottom box 1 at the downstream position of the drainage pipe 3, and the upper end of the feeding hopper 4 is tangent to the outer wall of the drainage pipe 3.

[0017] Among them, a rectangular openwork 101 is provided at the contact point between the bottom plate of the storage tank 1 and the ground.

[0018] Among them, the rotating wheel seat 2 is provided with symmetrical pulleys 201, and the pulleys 201 are metal blade wheels.

[0019] The drain pipe 3 has a spiral guide plate 301 fixed in its inner cavity, and ring rails 304 are fixed at its upstream and downstream ends. The ring rails 304 have grooves that engage with the pulleys 201. The drain pipe 3 rotates between two rotating wheel seats 2.

[0020] Among them, the drain pipe 3 has evenly spaced drainage holes 303 on the pipe wall corresponding to the position of the hopper 4, and the drain pipe 3 on one side of the drainage hole 303 also has a corresponding enlarged soil leakage hole 302.

[0021] In Example 2, based on Example 1, the lower end of the storage tank 1 is a sloping structure that fits into the ground, and the hopper 4 has a structure that is wider at the top and narrower at the bottom.

[0022] The following further explains and illustrates the function and effect of each structure mentioned above, so that those skilled in the art can better understand the technical solution: The collection tank 1, as the main container of the device, is used to collect rainwater. The rectangular open end 101 at the contact point between its bottom plate and the ground facilitates the direct entry of surface runoff and rainwater into the tank, while also enhancing the fit between the device and the ground and reducing soil erosion. Rotating wheel seats 2 are fixedly installed at the top left and right ends of the collection tank 1, which are equipped with symmetrical pulleys 201. The pulleys 201 adopt a metal blade wheel design, which not only provides support, but also cuts debris with the blade surface when the drain pipe 3 rotates, reducing friction and blockage, and ensuring smooth rotation. A drain pipe 3, rotatably mounted between two rotating wheel seats 2, is engaged with the grooves of pulleys 201 via ring rails 304 fixed at its upstream and downstream ends. This allows the drain pipe 3 to rotate flexibly between the rotating wheel seats 2, promoting uniform distribution of internal materials. A spiral guide plate 301 fixed inside the drain pipe 3 guides the water flow to form a spiral motion, enhancing centrifugal force and effectively separating mud and water from rainwater. The drain pipe 3 has evenly spaced drainage holes 303 on its wall corresponding to the position of the hopper 4, allowing the separated water to seep out and flow back to the collection tank 1. An enlarged drainage hole 302 on one side facilitates the centralized discharge of separated mud and sand. The hopper 4, located downstream of the drain pipe 3, is tangent at its upper end to the outer wall of the drain pipe 3, ensuring that the mud and sand discharged from the drainage hole 302 can be smoothly introduced. The hopper 4 has a structure that is wider at the top and narrower at the bottom, which facilitates the collection and guidance of mud and sand, preventing accumulation. In addition, the lower end of the collection tank 1 has a sloping structure that fits tightly against the ground, further improving the stability of the device and guiding the water flow to converge at the bare opening 101, thus optimizing the rainwater collection efficiency.

[0023] Working Principle: During operation, surface runoff and rainwater, guided by the inclined structure at the lower end of the collection tank 1, enter the device through the open opening 101 in its bottom plate. The rainwater containing silt and sand entering the collection tank 1 then flows into the rotatable drain pipe 3. The drain pipe 3 is stably supported and can rotate flexibly by engaging the metal-bladed pulleys 201 in the rotating wheel seat 2 via the ring rails 304 at both ends. When the water flows through the drain pipe 3, the spiral guide plate 301 fixed in its inner cavity forces the water to move in a spiral motion, generating centrifugal force, which causes the heavier silt and sand in the water to be thrown towards the pipe wall. Under the action of centrifugal force, the separated water seeps out through the evenly spaced drainage holes 303 on the pipe wall and flows back into the collection tank 1 for storage; at the same time, the separated and accumulated silt and sand move towards the pipe wall under the action of rotation and are finally discharged through the enlarged diameter leakage hole 302. The discharged silt falls precisely into the hopper 4, located downstream of the drain pipe 3 and tangential to the pipe wall at its upper end. The hopper 4 has a wider top and narrower bottom structure, effectively receiving and guiding the silt to prevent accumulation inside the device. Throughout the process, the continuous rotation of the drain pipe 3 not only promotes efficient centrifugal separation of silt and water but also prevents clogging of the drain hole 303 and the soil leakage hole 302 through its movement. Furthermore, the metal cutting edge design of the pulley 201 further ensures smooth rotation.
