Description

Technical Field

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

[0002] Rainwater harvesting devices have a wide range of applications, especially suitable for areas with uneven water resource distribution or limited tap water supply, covering multiple fields.

[0003] In some areas that are frequently affected by rain and wind, the collection efficiency of existing rainwater harvesting devices is significantly limited. These areas face weather conditions where rain and wind coexist year-round, and raindrops often fall at an angle rather than vertically under the influence of wind.

[0004] The currently commonly used planar collection structure cannot adapt to the deviation of rainwater trajectory caused by wind. A large amount of rainwater will deviate from the planar collection range due to the effect of wind direction, or only the edge area will collect rainwater, resulting in the actual collection volume being far lower than the theoretical precipitation. Utility Model Content

[0005] To address the technical problems existing in the background art, the utility model provides a rainwater storage device that solves the problem mentioned above where the rainwater trajectory is deviated due to the inability to adapt to wind force, a large amount of rainwater deviates from the planar collection range due to wind direction, or only the edge area receives rainwater, resulting in the actual collection amount being far lower than the theoretical precipitation.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A rainwater storage device includes a support assembly, a sensing assembly, and a collection assembly. The support assembly includes a support rod with a rotary motor fixedly mounted on its upper end. A collection assembly is disposed on the side of the rotary motor, and a sensing assembly is disposed in the middle of the support rod. The sensing assembly includes an angle sensor mounted in the middle of the support rod, with an extension rod at the rear end of the angle sensor and a tail fin fixed to the rear end of the extension rod. The collection assembly includes a bracket base with the rotary motor fixed to its rear side. A rainwater collection plate is installed inside the bracket base, and a water collection trough is fixed to the lower end of the bracket base, corresponding to the lower end of the rainwater collection plate.

[0007] Preferably, a water collection pipe is installed at the lower end of the water collection tank, the support rod is a hollow structure, an annular groove is installed in the middle of the support rod, the inner side of the annular groove is connected to the inside of the support rod, and the lower end of the water collection pipe is located in the annular groove.

[0008] Preferably, a support bracket is fixed to the lower end of the bracket base, and the water collection pipe is fixed on the support bracket.

[0009] Preferably, the support rod has a control line inside, which is connected to an angle sensor and a rotary motor.

[0010] Preferably, a support base is fixed to the lower end of the support rod.

[0011] Preferably, multiple sets of water guide strips are fixed to the outer side of the rain collection plate, and the water guide strips are arranged longitudinally.

[0012] This utility model has the following advantages and beneficial effects: In this utility model: The tail fin senses real-time wind direction changes and transmits the wind direction signal to an angle sensor via an extension rod. The angle sensor quantifies the offset angle and drives a rotary motor, which in turn adjusts the orientation of a fixed-angle rain collection plate via a support base. This ensures that the tilted surface always faces the actual direction of the rainwater after the wind shifts, preventing rainwater from deviating from the collection range or only being collected at the edges. Simultaneously, the fixed-angle design of the rain collection plate ensures efficient rainwater convergence, with a corresponding collection trough at the bottom for centralized rainwater accumulation. The overall system operation flow is: wind direction sensing - signal transmission - precise orientation adjustment - efficient collection. It dynamically adapts to changes in rainwater trajectory caused by different wind directions, significantly reducing the misalignment between the collection range and the rainwater trajectory, and significantly increasing the actual amount of rainwater collected.

Detailed Implementation

[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 some embodiments of this utility model, but not all embodiments.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example like Figures 1-4 As shown, a rainwater storage device includes a support assembly 1, a sensing assembly 2, and a collection assembly 3. The support assembly 1 includes a support rod 12, a rotary motor 4 fixedly mounted on the upper end of the support rod 12, a collection assembly 3 disposed on the side of the rotary motor 4, and a sensing assembly 2 disposed in the middle of the support rod 12. The sensing assembly 2 includes an angle sensor 21, which is mounted in the middle of the support rod 12. An extension rod 22 is disposed at the rear end of the angle sensor 21, and a tail fin plate 23 is fixed at the rear end of the extension rod 22. The collection assembly 3 includes a bracket base 31, which is fixed to the rotary motor 4 at the rear. A rainwater collection plate 32 is installed inside the bracket base 31, and a water collection trough 33 is fixed at the lower end of the bracket base 31, with the water collection trough 33 corresponding to the lower end of the rainwater collection plate 32.

[0018] During use, the extension rod 22 mechanically transmits the deflection action of the tail fin 23 caused by the wind direction to the angle sensor 21. The angle sensor 21 receives the deflection angle signal of the tail fin 23 through the extension rod 22, converts it into a recognizable electrical signal, quantifies the "direction angle of the rainwater trajectory deflection due to wind force", and provides an adjustment basis for the rotary motor 4. After receiving the "rainwater deflection direction" signal transmitted by the angle sensor 21, the rotary motor 4 drives the entire collection assembly 3 to rotate synchronously through rotation. The water collection tank 33 receives the rainwater that naturally slides down from the inclined rain collection plate 32.

[0019] like Figures 1-4 As shown, a water collection pipe 34 is installed at the lower end of the water collection trough 33. The support rod 12 has a hollow structure, and an annular groove 5 is installed in the middle of the support rod 12. The inner side of the annular groove 5 is connected to the inside of the support rod 12. The lower end of the water collection pipe 34 is located in the annular groove 5. The rainwater collected by the water collection trough 33 is guided downward through the water collection pipe 34. Since the water collection pipe 34 rotates with the collection component 3, the annular groove 5 contains the rotation of the water collection pipe 34 through the annular structure, ensuring that the lower end of the water collection pipe 34 is always in the groove. After the rainwater smoothly enters the annular groove 5, it flows into the hollow support rod 12 through the connection structure between the annular groove 5 and the support rod 12, completing the seamless transfer of rainwater in the rotating state.

[0020] like Figures 1-4As shown, a support bracket 35 is fixed to the lower end of the bracket base 31, and the water collection pipe 34 is fixed on the support bracket 35. The support bracket 35 enhances the installation stability and positional accuracy of the water collection pipe 34.

[0021] The angle sensor 21 and the rotary motor 4 are powered by an external power supply, with the power supply wires passing through the bottom of the support rod 12.

[0022] like Figures 1-4 As shown, a support base 11 is fixed to the lower end of the support rod 12. The support base 11 is directly connected to the support rod 12, providing a vertical and stable support foundation for the support rod 12, ensuring that the support rod 12 remains upright. The support base 11 can adjust the distance between the support rod 12 and the ground, thereby adjusting the height of the rainwater storage device.

[0023] like Figures 1-4 As shown, multiple sets of water guide strips 321 are fixed on the outside of the rain collection plate 32. The water guide strips 321 are arranged longitudinally. After the rain collection plate 32 is adjusted to face the direction of the rainwater, when the rainwater falls on the plate surface, the dispersed rainwater is constrained in the longitudinal channel, reducing the loss of rainwater during the transmission process.

[0024] When using the rainwater storage device, the support base 11 is first in close contact with the ground, and the support base 11 provides stable support for the support rod 12, so that the support rod 12 remains vertical. When rainfall occurs or is predicted to occur, the sensing component 2 is the first to activate. The tail fin 23 deflects under wind force, and this deflection is mechanically transmitted to the angle sensor 21 via the extension rod 22. The angle sensor 21 receives the deflection angle signal from the tail fin 23 and converts it into a recognizable electrical signal, which is directly transmitted to the rotary motor 4 to quantify the "direction angle of the rainwater trajectory deflection due to wind force." Upon receiving the "rainwater deflection direction" signal from the angle sensor 21, the rotary motor 4 immediately executes a rotation, causing the fixed support base 31 and the entire collection component 3 to rotate synchronously. During rotation, the rain collection plate 32 adjusts its orientation with the support base 31 until it faces the direction of the incoming rainwater. At this point, the longitudinal water guide strips 321 on the outer side of the rain collection plate 32 can collect rainwater to the maximum extent. The water guide strip 321 confines the dispersed rainwater within the longitudinal channel, reducing lateral diffusion and loss of rainwater on the surface, allowing rainwater to flow quickly along the channel formed by the water guide strip 321 to the lower end of the rain collection plate 32. Subsequently, the rainwater naturally slides into the corresponding water collection trough 33, completing initial collection. The rainwater in the water collection trough 33 flows downwards under gravity and is guided by the water collection pipe 34 fixed to the support bracket 35. Since the water collection pipe 34 rotates synchronously with the collection assembly 3, and the annular groove 5 in the middle of the support rod 12 contains the rotation of the water collection pipe 34 through its annular structure, it ensures that the lower end of the water collection pipe 34 is always within the annular groove 5, preventing rainwater leakage. After successfully entering the annular groove 5, the rainwater flows into the hollow support rod 12 through the connection between the annular groove 5 and the support rod 12. The rainwater flowing into the support rod 12 is then transported downwards along the rod body. A water storage container can be connected to the lower end of the support rod 12 according to actual needs to achieve efficient rainwater storage.

[0025] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
