A non-powered uniform slow-release device and a non-powered storage device with the device

technical field

The utility model belongs to the technical field of water collection and distribution devices, in particular to a non-powered uniform slow-release device and a non-powered storage device with the device.

Background technique

Water and solutions with similar properties to water are generally released from the container in two ways: the first is to use gravity to release the water through low-level pipes, valves, etc.; the second is to use water pumps or other power devices to lift water from the container Or send it out for use. The gravity flow release method does not require external power, but the amount of released water will gradually decrease due to the gradual decrease of the water level in the container, and its gravity will change, making it difficult to use the effluent in the container uniformly and with a controllable flow rate. Especially, it is difficult to adopt this method in an environment that requires slow and uniform utilization of water over a long period of time. Using water pumps or other power devices, the water in the container can be used in a stable flow rate, but in many environments, power sources and electromechanical equipment cannot be provided. Even if the power source is provided, it will be difficult to use and promote because of the high cost of project implementation and complicated operation and maintenance.

The state proposes to build a sponge city, which means that the city can absorb, store, infiltrate, and purify water when it rains like a sponge, and "release" the stored water and use it when needed. With the large-scale development of sponge city construction, a large number of rainwater storage facilities and storage facilities have been constructed. Usually, in order to use the stored rainwater, a power source needs to be provided. In many places, due to the power supply capacity and transmission distance, the construction cost is too high, and the operation and maintenance are complicated, so it cannot be widely used. At the same time, the existing wet ponds, biological retention facilities, infiltration ponds, rainwater wetlands and other facilities with regulating and storage functions overflow and discharge rainwater when there is a lot of rainwater; However, when there is no rainwater, the green space plants in these facilities need to be watered and maintained manually, and the water body needs to be replenished artificially to maintain the growth of aquatic plants and the landscape effect. If the stored rainwater can be released and utilized slowly and evenly without power when needed . It will greatly improve the effective utilization rate of rainwater and improve the use effect of these facilities.

The "Thirteenth Five-Year Plan" puts forward the goal of "by 2020, more than 50% of the country's controllable desertification land will be controlled". At the same time, there are still nearly 40 million hectares of barren hills and wasteland suitable for forests that need to be greened urgently. The "National Afforestation and Greening Planning Outline (2011-2020)" clearly requires that by 2020, the forest area will reach 223 million hectares, and the forest coverage rate will reach more than 23%. . However, at the current stage, most areas use power sources to use water resources in a planned way to maintain plants for desertification control and greening of barren hills, which is difficult to achieve in reality. There is an urgent need for a device that can release water slowly and evenly for plant maintenance without power.

As of 2014, the area of greenhouse facilities in my country has reached 4.109 million hectares, with an output value of more than 800 billion yuan, making great contributions to the balanced and stable supply of horticultural products, the continuous increase of farmers' income, and the continuous improvement of the level of agricultural modernization. At present, my country's protected cultivation accounts for more than 85% of the world's total, and its total area and total output both rank first. Devices that can release water slowly and evenly without power can be applied to facility agriculture, economic crop planting, greenhouse seedlings, etc., greatly saving water resources and labor costs.

In order to improve the existing technology, people have carried out long-term exploration and proposed various solutions. For example, the Chinese patent literature discloses a rainwater collection slow-release device [application number: CN201310315486.3], which is made of organic plastic material. It is beneficial to collect rainwater; there are many small micropores on the surface of the rainwater collection pipe to facilitate the collection of rainwater. The rainwater collection pipe is connected to the water inlet pipe, and the collected rainwater is collected in the collection box for storage.

Although the above solution solves the deficiencies of the prior art to a certain extent, the amount of released water will gradually decrease due to the water level in the container, and its gravity will change, making it difficult to use the effluent in the container uniformly and with a controllable flow rate.
