Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting devices, and in particular to a rainwater harvesting device for vegetable cultivation. Background Technology

[0002] As a key component of the vegetable planting industry, the construction of high-standard water storage ponds plays an irreplaceable role: by storing rainwater during the rainy season, the ponds provide irrigation water for crops during the dry season, effectively solving the problem of seasonal drought and significantly improving the comprehensive utilization efficiency of water resources; reducing the dependence of agricultural irrigation on external water sources and lowering transportation and irrigation costs; the construction of water storage ponds provides a stable water source guarantee for agriculture, reduces the risk of crop yield reduction due to drought, and ensures the stability of agricultural production.

[0003] In some areas, industrial pollution is severe, and the sulfur content in rainwater exceeds the standard. If vegetables are irrigated directly in the reservoir, it will damage the stomata and pores of the plant leaves, affecting photosynthesis and causing slow plant growth or even death.

[0004] Currently, some water storage tanks can regulate water quality by releasing purifying agents, but their level of intelligence is low, making it difficult to accurately add purifying agents based on the pH value of rainwater. In particular, when the sulfur content in rainwater is seriously excessive, adding a large amount of purifying agent will increase costs and make it not worthwhile. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a rainwater collection device for vegetable cultivation. Before storing rainwater, the pH value is tested. If the pH value is severely exceeded, collection is canceled; if the pH value is slightly exceeded, a purification agent is added to treat the rainwater until it meets the standard before collection.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a rainwater collection device for vegetable planting, including a water storage tank; the water storage tank is equipped with a partition, which divides the water storage tank into an upper conditioning zone and a lower storage zone; a stirring mechanism is installed in the middle of the top surface of the partition; a drain outlet is provided on the surface of the partition, and an electric sealing plate is hinged to the drain outlet; a water quality pH meter is installed on the top surface of the partition; a support rod is installed on the top surface of the partition, and the top of the support rod is located above the water storage tank and is equipped with a water purification mechanism; a first drain pipe is installed on the side wall of the water storage tank corresponding to the conditioning zone, and a second drain pipe is installed on the side wall of the water storage tank corresponding to the storage zone; both the first and second drain pipes are equipped with electric control valves; a controller is provided outside the water storage tank, and the controller is associated with the stirring mechanism, the electric sealing plate, the water quality pH meter, the water purification mechanism, and the electric control valves respectively.

[0007] The stirring mechanism consists of a drive motor and stirring blades. The drive motor is installed in the middle of the top surface of the partition, and the output shaft above the drive motor is connected to the stirring blades. When the purifying agent is added to the rainwater, the drive motor drives the stirring blades to rotate, which accelerates the mixing of rainwater and purifying agent.

[0008] The water purification mechanism consists of a box, a discharge port, and an electrically controlled feeder. The box is installed at the top of the support rod, and the discharge port is located at the bottom of the box. The electrically controlled feeder is installed at the discharge port. The box contains a purifying agent, and the electrically controlled feeder can discharge the purifying agent from the discharge port into the conditioning zone of the water storage tank at a uniform speed and with precision, thereby purifying rainwater with excessive sulfur content.

[0009] The working principle of the rainwater collection device for vegetable planting is as follows: when it rains, rainwater enters the partition. When the water quality pH value detector detects that the pH value of the rainwater is above the standard value, the electric control valve on the first drain pipe is closed and the electric sealing plate is open. The rainwater falls on the partition and then enters the storage area through the drain on the partition. When irrigation is needed, the electric control valve on the second drain pipe can be opened to allow the stored water to be discharged for irrigation.

[0010] When the pH value of the rainwater is detected to be below the standard value and the sulfur content is slightly excessive, the electrically controlled valve and the electric sealing plate on the first drainage pipe are both closed. The electrically controlled feeder of the water purification mechanism is activated to discharge the purifying agent into the conditioning zone at a uniform speed. At the same time, the stirring mechanism is activated to accelerate the mixing of the purifying agent with the rainwater, which helps to shorten the purification time. Once the water quality pH value detector detects that the pH value of the rainwater meets the standard, the water purification mechanism stops discharging, the stirring mechanism stops working, and the electric sealing plate is opened. The purified rainwater then enters the storage area for storage.

[0011] When the pH value of the rainwater is detected to be below the standard value and the sulfur content is severely excessive, the electric sealing plate is closed and the electric control valve on the first drain pipe is open. The excessive rainwater on the baffle will be discharged through the first drain pipe and will not be stored.

[0012] Compared with the prior art, the beneficial effects of this utility model are: before storing and collecting rainwater, the rainwater collection device for vegetable planting will test the pH value of the rainwater. If the pH value meets the standard, it will be stored and collected directly. If the pH value is slightly exceeded, a purification agent will be added to treat it until it meets the standard before storing and collecting. If the pH value is seriously exceeded, the collection will be canceled and the rainwater will be discharged directly, which helps to reduce costs and maximize profits. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] Reference Figure 1-2 This embodiment provides a rainwater collection device for vegetable planting, including a water storage tank 1; the water storage tank 1 is equipped with a horizontally arranged partition 2 by bolts, the partition 2 divides the water storage tank 1 into an upper conditioning zone 3 and a lower storage zone 4; the conditioning zone 3 is used for temporary water storage and water purification, and the storage zone 4 is used for long-term storage of qualified rainwater.

[0019] A stirring mechanism 5 is installed in the middle of the top surface of the partition 2. The stirring mechanism 5 consists of a drive motor and a stirring blade. The drive motor is installed in the middle of the top surface of the partition 2, and the output shaft above the drive motor is connected to the stirring blade. The stirring mechanism 5 is used to accelerate the mixing of rainwater and purifying agent.

[0020] The surface of the partition 2 is provided with two symmetrically distributed drain outlets, and an electric sealing plate 6 is hinged at the drain outlets to completely cover them; when the electric sealing plate 6 is opened, rainwater in the conditioning zone 3 can enter the storage zone 4.

[0021] The top surface of the partition 2 is bolted with a water quality pH meter 7, which can detect the pH value of rainwater in the conditioning zone.

[0022] The top surface of the partition 2 is bolted with a support rod 8. The top of the support rod 8 is located above the water storage tank 1 and is fitted with a water purification mechanism 9. The water purification mechanism 9 consists of a box, a discharge port, and an electrically controlled feeder. The box is installed at the top of the support rod, and the bottom of the box has a discharge port with an electrically controlled feeder installed at the discharge port. Purifying agent is placed inside the box, and the electrically controlled feeder can uniformly and accurately discharge the purifying agent inside the box from the discharge port into the conditioning zone of the water storage tank, thereby purifying rainwater with excessive sulfur content. The purifying agent can be granular sodium bicarbonate, which decomposes into sodium carbonate, carbon dioxide, and water after dissolving in water. Sodium carbonate is alkaline and can neutralize sulfides in acid rain, increasing the pH value of the rainwater.

[0023] A first drain pipe 10 is installed on the side wall of the water storage tank 1 corresponding to the conditioning zone 3, and a second drain pipe 11 is installed on the side wall of the water storage tank corresponding to the storage zone 4; both the first drain pipe 10 and the second drain pipe 11 are equipped with an electric control valve 12.

[0024] The water storage tank 1 is equipped with a controller, which is associated with the stirring mechanism 5, the electric sealing plate 6, the water quality pH meter 7, the water quality purification mechanism 9, and the electric control valve 12.

[0025] The working principle of the rainwater collection device for vegetable planting is as follows: When it rains, the rainwater first falls on the partition 2. When the water quality pH value detector 7 detects that the pH value of the rainwater is above the standard value, the electric control valve 12 on the first drain pipe 10 is closed and the electric sealing plate 6 is open. The rainwater first falls on the partition 2 and then enters the storage area 4 through the drain on the partition 2. When irrigation is needed, the electric control valve 12 on the second drain pipe 11 can be opened to cause the stored water to be discharged for irrigation.

[0026] When the pH value of the rainwater is detected to be below the standard value and the sulfur content is slightly excessive, the electrically controlled valve 12 and the electrically operated sealing plate 6 on the first drainage pipe 10 are both closed. The electrically controlled feeder of the water purification mechanism 9 is activated to uniformly discharge the purifying agent into the conditioning zone 3. At the same time, the stirring mechanism 5 is activated to accelerate the mixing of the purifying agent and the rainwater, which helps to shorten the purification time. Until the water quality pH value detector 7 detects that the pH value of the rainwater meets the standard, the water purification mechanism 9 stops discharging, the stirring mechanism 5 stops working, and the electrically operated sealing plate 6 is opened. The purified rainwater enters the storage zone 4 for storage.

[0027] When the pH value of the rainwater is detected to be below the standard value and the sulfur content is severely excessive, the electric sealing plate 6 is closed and the electric control valve 12 on the first drain pipe 10 is open. The excessive rainwater on the partition 2 will be discharged through the first drain pipe 10 and will not be stored.

[0028] In this embodiment, the circuit structure that links the working states of the stirring mechanism 5, the electric sealing plate 6, the water quality pH meter 7, the water quality purification mechanism 9, and the electric control valve 12 with the programmable controller is a conventional technical means in this field, and the structure of each electrical component is also in the prior art in this field, so it will not be described in detail.

[0029] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
