Description

Technical Field

[0001] The utility model relates to the technical field of urban rainwater reuse, in particular to a rainwater collection, storage and irrigation device for semi-arid areas. Background Art

[0002] In most cities in Northwest my country, abundant sunlight makes most of Northwest my country an arid or semi-arid area. Coupled with unreasonable human development, land desertification in Northwest my country is increasing rapidly.

[0003] Water resources in the northwest region are generally scarce. The abundant sunlight causes serious evaporation of water resources, resulting in low water resource utilization and uneven distribution of water resources in space and time, making it impossible to effectively irrigate vegetation in semi-desert areas. Due to the scarcity of water resources, many flower belts, lawns, tree gardens and other places in cities cannot be irrigated in time. Of course, some places also use rainwater collection and reuse devices, but the existing rainwater collection and reuse devices are relatively simple. On the one hand, there is a lack of good filtering facilities, resulting in some rainwater containing a lot of dust and particles, which in turn affects the irrigation of some plants. On the other hand, due to the serious evaporation of water resources, it is difficult to store a certain amount of water resources for a long time, and the utilization rate will also drop a lot. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, in this embodiment, a rainwater collection, storage and irrigation device for semi-arid areas is provided, which is mainly composed of a water collection panel 1, a filter device 2, a water storage tank 3, a water storage tank 4 and an irrigation mechanism. Among them, the water collection panel 1 is arranged obliquely on the ground, and multiple numbers can be set. The larger the area, the more water can be collected on rainy days; the filter device 2 is located lower than the water collection panel 1, that is, it can be set below the ground, and the water storage tank 3 and the water storage tank 4 are located lower than the filter device 2, and are also set below the ground. Specifically, the upper end of the filter device 2 is connected to the water collection panel 1 through a water guide pipe 10, and the lower end of the filter device 2 is connected to the water storage tank 3 through a water inlet pipe 11. The water storage tank 3 and the water storage tank 4 are connected, and the water storage tank 3 is divided into an untreated area 31 on the left and a treated area 32 on the right. A water quality treatment device is also provided on the top side of the water storage tank 3. The irrigation mechanism is externally connected to the water storage tank 4 and connected to the ground for vegetation irrigation.

[0026] During operation, the rainwater collected by the water collecting panel 1 on rainy days can flow into the filter device 2 through the water guide pipe 10 for filtration, and the filtered rainwater then flows into the untreated area 31 of the water storage tank 3 through the water inlet pipe 11; a first water pump 71 is also provided in the untreated area 31, and the output end of the first water pump 71 is connected to the water quality treatment device through a water pipe, and the first water pump 71 can transport the rainwater in the untreated area 31 to the water quality treatment device for water sterilization treatment; a second water pump 72 is also provided in the treated area 32, and the input end of the second water pump 72 is connected to the water quality treatment device through a water pipe, and the second water pump 72 can transport the rainwater treated in the water quality treatment device to the treated area 32 for storage. At the same time, a third water pump 73 is also provided in the treated area 32, and the output end of the third water pump 73 is connected to the water storage tank 4 through a water pipe, and the third water pump 73 can transport the clean water in the treated area 32 to the water storage tank 4 for re-storage. Of course, an ultraviolet disinfection lamp 9 is also provided in the water tank 4, which can sterilize and disinfect the water in the water tank 4 again to improve the quality of the purified water.

[0027] Through the above design, it can be seen that the present embodiment sets the water collection panel 1 on the ground to collect water, and its filtering device 2, water storage tank 3, and water storage tank 4 can all be set below the ground, so that the evaporation loss of water resources can be reduced, and sufficient rainwater can be stored by relying on the water storage tank 3 and the water storage tank 4, thereby improving the utilization efficiency of water resources, which is beneficial to long-term irrigation water. In addition, the purification degree of rainwater after filtration, sterilization and disinfection is relatively high, which is beneficial to the healthy and rapid growth of vegetation.

[0028] Specifically, the irrigation mechanism in this embodiment includes a fourth water pump 50 disposed in the water storage tank 4, a water outlet pipe 51 connected to the output end of the fourth water pump 50, and a sprinkler 52 connected to the water outlet pipe 51, and a plurality of water outlet holes 520 are provided at the upper end of the sprinkler 52. When irrigation is required, the fourth water pump 50 can transport the clean water in the water storage tank 4 to the sprinkler 52 through the water outlet pipe 51, and then irrigate the surrounding area through the plurality of water outlet holes 520 of the sprinkler 52. Through the design of the water collection panel 1, the filter device 2, the water storage tank 3, the water storage tank 4 and the irrigation mechanism, rainwater can be well collected, filtered and stored, and finally the clean water is irrigated to various vegetation on the ground through the irrigation mechanism, thereby improving the reuse rate of water resources and solving the problem of irrigation water shortage in some areas.

[0029] Specifically, the filter device 2 of this embodiment is composed of a box body 20 and a silt baffle layer 21, a gravel barrier layer 22 and an activated carbon adsorption layer 23 arranged from top to bottom inside the box body 20, wherein the silt baffle layer 21, the gravel barrier layer 22 and the activated carbon adsorption layer 23 are separated by a water-blocking plate 24 and connected by a filter plate 25. The presence of the water-blocking plate 24 enables each layer to be fully filtered, and the filter plate 25 can be a common water filtering material such as a sponge to ensure that water can flow downward. Because the silt baffle layer 21 is used to filter out larger impurities, the gravel barrier layer 22 is used to filter out smaller impurities, and the activated carbon adsorption layer 23 is used to adsorb small particles and solutes, the combination of the three layers of filtration can achieve a better filtration effect.

[0030] Specifically, the water treatment device includes a water treatment box 60 disposed on the top side of the water storage tank 3 and an ultrasonic sterilization device 61 disposed inside the water treatment box 60. In order to prevent the rainwater in the untreated area 31 from staying for too long and deteriorating, the rainwater transported to the water treatment box 60 is treated by the ultrasonic sterilization device 61 to kill microorganisms and prevent the water from eutrophication and deterioration in the untreated area 31.

[0031] In addition, in order to prevent excessive rainwater in the untreated area 31 and the treated area 32 in the water tank 3 from overflowing from each other, this embodiment is provided with liquid level sensors 8 on the high side walls of the untreated area 31 and the treated area 32 in the water tank 3 to facilitate timely monitoring of the water level and ensure the safety of the internal water resources.
