Description

Technical Field

[0001] The utility model relates to the field of rainwater collection, in particular to a device for collecting rainwater for watering green space. Background Art

[0002] There are many green plants and green areas in the park, and the staff need to irrigate them regularly. In order to save water resources, a rainwater collection device can be used to collect rainwater and use rainwater for irrigation. Patent document: CN 213153260 U proposed a rainwater collection and irrigation device, including a ground, a working box fixedly installed inside the ground, a collecting box welded on the top of the working box, a collecting mechanism arranged inside the collecting box, a sponge block placed inside the collecting box, a transmission mechanism arranged on the right side of the collecting box, an irrigation mechanism arranged inside the ground, and a vegetable garden placed on the top of the ground. The problem with this technical solution is that most of the above-mentioned existing rainwater collection and irrigation devices are not provided with a rainwater collection and control structure. Rainwater is collected by the rainwater collection device in rainy weather, but the green space is irrigated by natural rainwater in rainy weather, so the collected rainwater will not be used. During the irrigation interval, rainwater stored in a water tank or a reservoir is prone to produce odor and bacteria. The rainwater at this time is not suitable for irrigation work, and the staff can only discharge it, which not only wastes water resources, but also there is no rainwater to irrigate the green space when the irrigation date arrives, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: the above-mentioned existing rainwater collection and irrigation devices are mostly not provided with a rainwater collection and control structure, and rainwater is collected by the rainwater collection device in rainy weather, but the green space is irrigated by natural rainwater in rainy weather, so the collected rainwater will not be used. During the irrigation interval, rainwater is stored in a water tank or a reservoir, which is prone to produce odor and bacteria. The rainwater at this time is not suitable for irrigation work, and the staff can only discharge it, which not only wastes water resources, but also there is no rainwater to irrigate the green space when the irrigation date arrives, which is inconvenient to use.

[0004] In order to solve the problems existing in the prior art, the utility model provides a device for collecting rainwater for irrigating green spaces, comprising a collection well, a water pipe and a water storage tank. A water pipe is provided between the bottom of the collection well and the water storage tank, a filter is provided on the periphery of the water pipe, a liquid level sensor, a stirring motor and a control module are respectively provided on the top of the water storage tank, and a first conduit and a second conduit are respectively provided on one side of the water storage tank.

[0005] Furthermore, a rain sensor is provided on the top of the collection well, and the rain sensor is electrically connected to the control module. When rainy weather comes, the rain sensor can be used for detection, so that the control module can control the operating status of other devices according to the rain signal.

[0006] Furthermore, a stirring assembly is provided inside the water storage tank at the bottom of the stirring motor, and the stirring motor is electrically connected to the control module. After the stirring motor is started, the stirring assembly is driven to rotate, and the rainwater in the water storage tank is stirred and mixed with the reagent regularly added into the water storage tank by the staff, thereby increasing the fluidity of the rainwater in the water storage tank and making the rainwater fresh.

[0007] Furthermore, a liquid level detection probe is provided inside the water storage tank at the bottom of the liquid level sensor, and the liquid level sensor is electrically connected to the control module. The liquid level of rainwater in the water storage tank is detected by the liquid level detection probe at the bottom of the liquid level sensor, so that the control module can control the operating status of other devices according to the liquid level data.

[0008] Furthermore, a first valve is disposed on the periphery of the first conduit, and the first conduit is connected to an external irrigation device. After the first valve is opened, the water in the water storage tank is pumped into the irrigation device in cooperation with an external water pump for use.

[0009] Furthermore, a second valve is disposed on the periphery of the second conduit, and the second conduit is connected to the park cleaning equipment. After the second valve is opened, the water in the water storage tank is pumped to the park cleaning equipment or other water-using areas in cooperation with an external water pump for use.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] During the watering interval, the utility model controls the valve of the second conduit to open periodically by the control module, and extracts a part of the rainwater in the water tank by cooperating with the external water pump and the liquid level detection function of the liquid level sensor. During the extraction process, the control module controls the stirring motor to start and drives the stirring component to rotate, and cooperates with the medicine regularly added in the water tank by the staff to stir and mix the rainwater in the water tank, thereby increasing the fluidity of the rainwater in the water tank and performing fresh treatment on the rainwater, solving the problem that the existing rainwater cannot be used for watering due to the breeding of odor bacteria due to the long-term storage, and increasing the practicality of the device.
