Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, and in particular to a self-flowing irrigation system for a water storage layer under the roots of plants in an aerial garden. Background Technology

[0002] Fourth-generation architecture, also known as sky garden housing, vertical garden eco-housing, or urban forest garden architecture, refers to high-quality improved housing that combines green ecological concepts with modern high-rise buildings, upgrading the living environment through technologies such as sky gardens and vertical greening. Currently, irrigation for the plants in sky gardens is mostly done through sprinkler and / or drip irrigation, with the irrigation system pressurizing ground water to supply the homes. Because the irrigation water is slightly corrosive, pressurized systems can only use metal pipes lined with plastic, which not only results in high pipe costs but also presents problems with maintenance and replacement.

[0003] Based on this, this application provides a self-flowing irrigation system for the water storage layer under the roots of plants in an aerial garden, which realizes self-flowing irrigation and solves the problems of traditional pressurized irrigation. Utility Model Content

[0004] This invention aims to solve the technical problems existing in the prior art. Therefore, this invention provides a self-flowing irrigation system with a water storage layer under the roots of plants in an aerial garden, achieving self-flowing irrigation.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A self-flowing irrigation system for the root water storage layer of plants in a rooftop garden is provided for replenishing water to the sand and gravel water storage layer at the bottom of the planting pits. It includes a water storage tank, a main irrigation pipe, floor branch pipes, a water supply pipe, a first solenoid valve, a second solenoid valve, and a third solenoid valve. The water storage tank is installed on the rooftop. The main irrigation pipe is connected to the water storage tank via a self-flowing pipe, extending from the rooftop to the floortop, with the end at the floortop sealed. The floor branch pipes are installed on each floor to supply water to various planting pits on that floor. The water supply pipe is located in the planting pit on each floor, with one end connected to the floor branch pipe and the other end inserted into the sand and gravel water storage layer. Multiple first solenoid valves are located on the main irrigation pipe below each floor branch pipe; multiple second solenoid valves are located on each floor branch pipe; and multiple third solenoid valves are located on each water supply pipe.

[0007] In some alternative embodiments, the first solenoid valve is a normally open solenoid valve, and the second and third solenoid valves are normally closed solenoid valves.

[0008] In some optional embodiments, the planting pit consists of a planting soil layer, a permeable isolation layer, a sand and gravel water storage layer, and a waterproof layer from top to bottom, wherein the sand and gravel water storage layer is filled with coarse sand with a particle size of 3 to 5 mm.

[0009] In some alternative embodiments, the planting pit is also provided with a water level pipe, the bottom of which extends into the bottom of the sand and gravel water storage layer, and its bottom sidewall is provided with several water inlet holes.

[0010] In some alternative embodiments, a liquid level sensor is also provided inside the water level tube.

[0011] In some alternative implementations, the liquid level sensor is a multi-point photoelectric liquid level sensor.

[0012] In some optional embodiments, a nutrient supplementation device is also included, which includes a nutrient storage tank and a metering tank. The nutrient storage tank is connected to the metering tank via a gravity flow pipe. A float valve is installed at the inlet of the metering tank, and the outlet is connected to the irrigation main pipe via a connecting pipe.

[0028] Example 1

[0029] This embodiment provides a self-flowing irrigation system for the root-layer water storage layer of plants in a rooftop garden, used to replenish water to the sand and gravel water storage layer at the bottom of planting pit 1. The planting pit of this embodiment is shown in the attached diagram. Figure 2 As shown, the planting pit 1 consists of a planting soil layer 1.1, a permeable isolation layer 1.2, a sand and gravel water storage layer 1.3, and a waterproof layer 1.4 from top to bottom. The permeable isolation layer can be made of non-woven fabric to isolate the planting soil and prevent it from entering the sand and gravel water storage layer and causing blockage. The sand and gravel water storage layer is filled with coarse sand with a particle size of 3-5mm. The waterproof layer is an enhanced building drainage measure to prevent water seepage from the planting pit.

[0030] As attached Figure 1 As shown, the self-flowing irrigation system under the root zone of the rooftop garden in this embodiment includes a water storage tank 2, an irrigation main pipe 3, floor branch pipes 4, a water supply pipe 5, a first solenoid valve 6, a second solenoid valve 7, and a third solenoid valve 8, wherein:

[0031] The water storage tank 2 is installed on the roof and is equipped with a breather pipe, an overflow outlet, and a tap water supply pipe. A float valve is installed at the inlet of the supply pipe to ensure the water level in the tank. The irrigation main pipe 3 is connected to the water storage tank 2 via a gravity-flow pipe, extending from the roof to the ground floor, with the end at the ground floor sealed. Floor branch pipes 4 are installed on each floor to supply water to the various planting pits 1 on that floor. The supply water pipe 5 is located in the planting pit 1 on each floor, with one end connected to the floor branch pipe 4 and the other end inserted into the sand and gravel water storage layer 1.3, as shown in the attached diagram. Figure 2As shown; specifically: the water supply pipe extends into the bottom of the sand and gravel water storage layer, and multiple water outlets are provided on the outer wall of the section located in the sand and gravel water storage layer, and are wrapped with permeable cloth; multiple first solenoid valves 6 are respectively located on the main irrigation pipe 3 below the branch pipe 4 on each floor; multiple second solenoid valves 7 are respectively located on the branch pipe 4 on each floor; multiple third solenoid valves 8 are respectively located on each water supply pipe 5. Preferably, in this embodiment, the first solenoid valve 6 is a normally open solenoid valve, and the second solenoid valve 7 and the third solenoid valve 8 are normally closed solenoid valves.

[0032] Preferred options are listed below. Figure 2 As shown, in this embodiment, a water level pipe 9 is also provided in the planting pit 1. The bottom of the water level pipe 9 extends into the bottom of the sand and gravel water storage layer 1.3, and its bottom sidewall is provided with several water inlet holes. The water level pipe 9 and the planting pit 1 form a communicating vessel, and the water level in the water level pipe can represent the water level in the planting pit. The water level status in the water level pipe can be observed to determine whether water replenishment is needed. Furthermore, this embodiment also provides a liquid level sensor 10 in the water level pipe 9, which can detect changes in water level. In one embodiment, a high-level water level sensor and a low-level water level sensor can be set. When the high-level water level sensor detects a signal, water replenishment stops; when the low-level sensor detects a signal, water replenishment starts. In another embodiment, a multi-point photoelectric liquid level sensor can be used. This type of liquid level sensor can detect multiple liquid levels simultaneously. For example, the conventional multi-point sensor from Nengdian Technology can detect four different liquid levels. Similarly, when the detected liquid level reaches a set depth, water replenishment stops; when the detected liquid level is below the set depth, water replenishment starts. In other embodiments, other liquid level sensors may be used to detect changes in water level within the sand and gravel aquifer.

[0033] Working principle: When the water level in a planting pit on a certain floor is lower than the set value, the host computer can control the third solenoid valve on the water supply pipe in the planting pit to open, control the second solenoid valve on the floor branch pipe of that floor to open, and control the first solenoid valve on the irrigation main pipe below the floor branch pipe to close. At this time, the water path from the water storage tank to the planting pit is opened to replenish water until the water level in the planting pit reaches the set value. Then, the host computer controls the third solenoid valve on the water supply pipe in the planting pit to close, controls the second solenoid valve on the floor branch pipe of that floor to close, and controls the first solenoid valve on the irrigation main pipe below the floor branch pipe to open.

[0034] It is necessary to note that the actions of the solenoid valves described above are all synchronous. All of the above controls are performed by the host computer in the control room, which is a conventional control method in the field of logic control technology and will not be elaborated upon here. The control logic of this embodiment is set to perform water replenishment irrigation in sequence; that is, the planting pit that issues a water replenishment request first will be supplied first.

[0035] Drainage outlets can also be installed on the planting pits, with the outlets located in the planting soil layer, to prevent excessive watering or even water overflowing the planting pits due to equipment malfunction.

[0036] Example 2

[0037] Based on Example 1, this example further includes a nutrient supplementation device, as shown in the attached document. Figure 1 As shown, the nutrient replenishment device includes a nutrient storage tank 11 and a metering tank 12. Both the nutrient storage tank 11 and the metering tank 12 are equipped with a breathing tube at the top. The nutrient storage tank 11 is connected to the metering tank 12 through a gravity flow pipe. A float valve is installed at the inlet of the metering tank 12, which can adjust the position of the float ball to control the amount of nutrient in the metering tank. The outlet of the metering tank 12 is connected to the irrigation main pipe 3 through a connecting pipe, and a fourth solenoid valve 13 is installed on the connecting pipe.

[0038] Working principle: When the planting soil in a planting pit needs to be replenished with nutrients, the water path of the planting pit is opened in the manner described in Example 1, and the fourth solenoid valve is opened at the same time, so that the nutrients flow into the planting pit with the irrigation water and are mixed and diffused in the sand and gravel water storage layer.

[0039] If nutrient supplementation is required separately, simply install a fifth solenoid valve on the gravity flow pipe between the water storage tank and the irrigation main pipe, and close the fifth solenoid valve to allow for independent nutrient addition.

[0040] Example 3

[0041] Based on Embodiment 1 or Embodiment 2, this embodiment further includes a rainwater collection device, as shown in the attached diagram. Figure 1 As shown, the rainwater harvesting device includes a filter tank 14 and a water pump 15. The filter tank 14 is located below the roof and is used to receive and filter rainwater from the roof. The water pump 15 is connected to the filter tank 14 and the water storage tank 2, and is used to pump the filtered rainwater into the water storage tank. The rainwater harvesting device designed in this embodiment realizes the recycling of rainwater and improves the utilization rate of water resources.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
