[0002] The basic components of landscape are extensive and diverse, which can be mainly divided into two categories. One is soft landscape, which is often derived from nature, such as lush trees, flowing water, gentle and soft wind, delicate and soft rain, warm and bright sunlight, and vast and boundless sky. They create a harmonious and peaceful natural atmosphere together. The other is hard landscape, which is mostly man-made, such as flat and orderly paving, solid and stable walls, delicate and elegant railings, and various carefully designed landscape structures. The water spraying device is one of the landscape structures.

DETAILED DESCRIPTION

[0024] Please refer to Figs. 1-2 The present application provides a technical scheme: a landscape water spraying device based on photovoltaic power supply, comprising a main water tank 1, a vice water tank 2 and a photovoltaic power supply system 3, the upper part of the main water tank 1 is provided with a water inlet pipe 11 communicating with the inside thereof, during use, the main water tank 1 is buried at a suitable position beside the landscape, and the water return groove of the landscape water spraying device is connected to the water inlet pipe 11 through a conduit, the water sprayed by the landscape water spraying device is collected by the water return groove and then recycled to the main water tank 1 through the water inlet pipe 11 for recycling.

[0025] The auxiliary water tank 2 is supported and fixed at a high position by the four legs 21 at the bottom, and the height of the bottom should be greater than the height of the nozzle of the water spraying device, and a water pump 4 is also arranged, and the photovoltaic power supply system 3 mainly comprises photovoltaic panels, storage batteries and inverters, and the specific structure and working principle are all prior art, and further description will not be given. The photovoltaic power supply system 3 is used for supplying power to the water pump 4, the inlet of the water pump 4 is connected to the inside below the side of the main water tank 1 through the water pumping pipe 41, the outlet of the water pump 4 is connected to the inside below the side of the auxiliary water tank 2 through the water delivery pipe 42, and the side of the water delivery pipe 42 is connected with the water using pipe 43.

[0026] In use, the water pump 4 is powered by the photovoltaic power supply system 3 to draw clean water from the main water tank 1 to the water delivery pipe 42, part of the water is sent to the water spraying device through the water using pipe 43 and sprayed from the nozzle, and the other part of the water is injected from the bottom to the auxiliary water tank 2 to supplement the clean water in the inside, and the water collected by the water return groove of the landscape water spraying device is also collected from the water inlet pipe 11 to the main water tank 1. In the use process, the water pump 4 cannot work normally due to insufficient light or rain, or the water pump 4 stops working when the photovoltaic power supply system 3 fails, and the water in the auxiliary water tank 2 will be discharged outward through the water delivery pipe 42, and the discharged water will flow to the water using pipe 43 and have a certain pressure, and can also be sprayed outward from the nozzle of the water spraying device. When the photovoltaic power supply system 3 is insufficient, the water spraying can continue for a period of time, and when the light is insufficient, the management personnel can choose whether to connect the water pump 4 to the generator for use or wait for good light to make the photovoltaic power supply system 3 continue to work to drive the water pump 4. When the photovoltaic power supply system 3 fails, there is enough time to repair.

[0027] The upper parts of the main water tank 1 and the auxiliary water tank 2 are connected with air pressure balance valves 23, respectively, which are communicated with the interiors of the main water tank 1 and the auxiliary water tank 2, so that the air pressures in the interiors of the main water tank 1 and the auxiliary water tank 2 are always balanced with the outside, and the normal water pumping or water discharging work of the system is ensured.

[0028] The water pump 4 has a certain resistance when it stops working to prevent the water in the auxiliary water tank 2 from flowing back to the main water tank 1, but a better way is to install a check valve 421 on the water delivery pipe 42 between the water pump 4 and the water using pipe 43, and the flow direction of the check valve 421 is toward the auxiliary water tank 2. Due to the arrangement of the check valve 421, the backflow of water to the main water tank 1 is better prevented.

[0029] In addition, the side of the auxiliary water tank 2 is connected with a water return pipe 24 above, and the other end of the water return pipe 24 is communicated with the upper part of the main water tank 1. When the water in the auxiliary water tank 2 is fully supplemented, it will flow back to the main water tank 1 from the water return pipe 24, so that too much water does not enter the auxiliary water tank 2 and overflow outward,

[0030] The front end surface of the auxiliary water tank 2 is provided with a vertical observation window 22, which is located in the middle of the front end of the auxiliary water tank 2. The surface of the observation window 22 is provided with scale lines 221, which are uniformly distributed. The water level in the auxiliary water tank 2 can be observed through the observation window 22, and the specific value of the water level can be observed through the scale lines 221.

[0031] In use, the main water tank 1 is buried in a suitable position beside the landscape, and the air pressure balance valve 23 leaks outside. The return water tank of the landscape water spraying device is connected to the water inlet pipe 11 through a conduit, and the auxiliary water tank 2 is supported by the supporting legs 21 at a certain height beside the landscape. The height of the bottom of the auxiliary water tank 2 needs to be greater than the height of the spray head of the water spraying device. The photovoltaic power supply system 3 and the water pump 4 are installed, and the pipeline is connected in place. The power supply line of the photovoltaic power supply system 3 is connected to the water pump 4, and finally the water pipe 43 is connected to the spray head of the water spraying device. In operation, the photovoltaic panel of the photovoltaic power supply system 3 charges the battery and supplies power to the water pump 4, which draws clean water from the main water tank 1 into the water delivery pipe 42. Part of the water is sent to the water spraying device through the water pipe 43 and sprayed from the spray head. The other part of the water is injected from the bottom into the auxiliary water tank 2 to supplement the clean water inside. When the water inside the auxiliary water tank 2 is fully supplemented, it will flow back to the main water tank 1 through the return water pipe 24 to avoid excessive water from overflowing outside. The water collected by the return water tank of the landscape water spraying device is also collected from the water inlet pipe 11 into the main water tank 1. In use, in case of cloudy and rainy weather or insufficient light to normally power the water pump 4 to work, or when the photovoltaic power supply system 3 fails, the water pump 4 stops working. The water in the auxiliary water tank 2 will be discharged outward through the water delivery pipe 42. Due to the setting of the check valve 421, the discharged water will only flow to the water pipe 43 and have a certain pressure, which can also be sprayed outward from the spray head of the water spraying device. In case of insufficient power supply of the photovoltaic power supply system 3, the water can continue to be sprayed for a period of time. In case of insufficient light, the management personnel can choose whether to connect the water pump 4 to the generator for use or wait for good light to make the photovoltaic power supply system 3 continue to work to drive the water pump 4. In case of failure of the photovoltaic power supply system 3, there is enough time to repair it.
