Description

Technical Field

[0001] The utility model belongs to the technical field of garden engineering, and in particular relates to a rainwater collection device used in landscape gardening engineering. Background Art

[0002] The garden rainwater collection device is a device used to collect rainwater in the garden area. The collected rainwater can be used for irrigation of garden plants, reducing dependence on conventional water resources such as tap water, and realizing effective utilization of water resources. It can also alleviate waterlogging: by collecting rainwater, it reduces the rapid gathering of rainwater on the ground, reduces the drainage pressure in the garden area and surrounding areas during heavy rains, and alleviates the problem of waterlogging.

[0003] Chinese patent application number CN202322231687.7 discloses a rainwater collection device for landscape gardening projects. By arranging a disc-shaped water tank, a connecting pipe, a funnel-shaped top, a drainage hole and a drainage grate, when it rains, rainwater falls on the drainage grate, passes through the drainage slit and falls to the outside of the funnel-shaped top, slides downward along the funnel-shaped top, passes through the drainage hole and enters the inside of the disc-shaped water tank. The drainage grate can receive fallen leaves, and the setting of the baffle can prevent the drainage slit from being blocked by fallen leaves. When the water flow rate is large, the connecting pipe discharges part of the water flow that falls on the funnel-shaped top to the ground, and takes away impurities on the upper surface of the funnel-shaped top, reducing the probability of the drainage hole being blocked, so that there is no need to frequently clean the rainwater collection device, which is more convenient to use. However, it still has the following defects:

[0004] First, although the eaves on the outer edge of the drain grate can block rainwater and prevent it from overflowing from the drain grate, it can also block impurities such as fallen leaves and branches, resulting in the fallen leaves not being thrown off by the rotation of the drain grate alone;

[0005] Secondly, when the floating plate does not reach the lower end of the drainage hole, the external ambient airflow is always connected to the inside of the disc-shaped water tank through the drainage hole, which will cause the water to evaporate quickly when the disc-shaped water tank is not completely filled, affecting the storage of water.

[0006] Therefore, it is necessary to provide a rainwater collection device for use in landscape engineering. Utility Model Content

[0007] The embodiment of the utility model provides a rainwater collection device used in landscape engineering to solve the problems in the prior art.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment 1:

[0030] Reference Figures 1 to 5 As shown, the embodiment of the utility model provides a rainwater collection device for landscape engineering, including a water storage tank 1 and a water collecting tray 2, the top of the water storage tank 1 is open, and a first wall 11 extending obliquely downward from the outer edge of the water storage tank 1 is formed at the opening of the water storage tank 1, and a water inlet channel 12 is formed at the end of the first wall 11, and a floating plate 3 is arranged in the water inlet channel 12, and the floating plate 3 is adapted to the cross-sectional profile of the water inlet channel 12, and a gap is left between the floating plate 3 and the inner wall of the water inlet channel 12, and a drain pipe 18 is also arranged on the water storage tank 1, and a valve 181 is installed on the drain pipe 18, and the drain pipe 18 is connected to an external water pipe;

[0031] The water collecting pan 2 is arranged just above the opening of the water storage tank 1, and the top wall of the water collecting pan 2 is configured as an inclined surface extending downward from the center portion thereof to the outer edge thereof, and the top wall of the water collecting pan 2 is provided with a drainage slit 21 which longitudinally penetrates the body of the water collecting pan 2;

[0032] Specifically, Figure 4 As shown, the drainage slits 21 are configured as a plurality of first water grooves 211 surrounding the water collecting tray 2 and extending from the center of the water collecting tray 2 to the outer edge thereof, and second water grooves 212 located between adjacent first water grooves 211. The second water grooves 212 extend along the circumference of the water collecting tray 2. Most of the rainwater can flow into the first wall 11 through the first water grooves 211, and the water flow between adjacent first water grooves 211 can flow into the first wall 11 through the second water grooves 212, thereby improving the rainwater collection efficiency of the water collecting tray 2.

[0033] In this embodiment, rainwater falls on the water collecting pan 2 and can fall on the first wall 11 at the opening of the water tank 1 through the drainage slit 21, while impurities such as fallen leaves and branches in the natural environment fall on the water collecting pan 2 and are blocked by the water collecting pan 2, and impurities such as fallen leaves and branches can slide down the inclined surface on the water collecting pan 2 and fall on the ground, thereby preventing fallen leaves or branches from accumulating on the water collecting pan 2 and causing blockage of the drainage slit 21; and when rainwater continuously flows into the water tank 1 through the water inlet channel 12, as the liquid level in the water tank 1 increases, the height of the float plate 3 also increases accordingly. Since the shape of the float plate 3 is adapted to the water inlet channel 12, no matter how high or low the liquid level in the water tank 1 is, the float plate 3 can cooperate with the water inlet channel 12 to cover the water inlet channel 12, which can greatly reduce the contact between the water body and the external environment and reduce the evaporation of water in the water tank 1.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, an overflow seam 13 (such as Figure 2 and Figure 3 ) and the height of the overflow seam 13 is less than the thickness of the floating plate 3;

[0036] In this embodiment, the overflow seam 13 can ensure that water can flow normally from the water inlet channel 12 into the water storage tank 1, and the height of the overflow seam 13 is less than the thickness of the float plate 3, which can ensure that the float plate 3 is always in the water inlet channel 12 to cover the water inlet channel 12 and prevent the float plate 3 from detaching from the water inlet channel 12; in another case, the bottom end of the water inlet channel 12 can directly extend to the bottom of the water storage tank 1, and by providing a perforation on one side wall of the bottom end of the water inlet channel 12, it can be ensured that the water flow in the water inlet channel 12 can overflow into the water storage tank 1.

[0037] Embodiment three:

[0038] Reference Figure 2 and Figure 5 A filter plate 14 is fixedly provided on the first wall 11, and a plurality of water-permeable holes 141 are provided on the filter plate 14. Water flows through the first wall 11 and the water-permeable holes 141 at the opening of the water storage tank 1 in sequence and flows into the water inlet channel 12. The collected rainwater can be secondary filtered through the filter plate 14 to remove small particles of impurities in the water.

[0039] Embodiment 4:

[0040] Reference Figure 2 and Figure 5A rotating shaft 22 is coaxially connected to the water collecting tray 2, and the rotating shaft 22 is rotatably connected to the mounting hole 142 at the center of the filter plate 14. A plurality of rotating blades 4 are installed on the top of the rotating shaft 2 and above the water collecting tray 2. The rotating blades 4 can be driven to rotate by the airflow (such as wind) in the natural environment, thereby driving the water collecting tray 2 to rotate. When the fallen leaves and branches on the water collecting tray 2 do not slide down smoothly, the fallen leaves or branches can be thrown off by the rotation of the water collecting tray 2.

[0041] Specifically, a waterproof cover 15 is installed at the lower end of the filter plate 14, and a rotary drive source 16 is installed in the waterproof cover 15. The output shaft of the rotary drive source 16 is transmission-connected with the rotating shaft 22. The rotary drive source 16 can specifically adopt a waterproof motor. When the inspection personnel of the landscape garden find that there are still fallen leaves on the water collection tray 2 that cannot be effectively thrown off due to the adsorption of water, or the air flow intensity is small, the inspection personnel can temporarily start the rotary drive source 16 to drive the water collection tray 2 to rotate and throw away the fallen leaves, branches, etc., or start the rotary drive source 16 at a fixed time, and can also regularly remove the fallen leaves, branches, etc. on the rotating tray.

[0042] Specifically, a drain port 17 is provided on one side wall of the water storage tank 1, and the drain port 17 is lower than the height of the waterproof cover 15, so that after a certain amount of water is collected in the water storage tank 1, the water that continues to flow into the water storage tank 1 can be discharged from the drain port 17, which can prevent the water from damaging the rotating drive source 16. The water discharged from the drain port 17 can directly irrigate nearby landscape trees.

[0043] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
