Description

Sloping tea garden seepage pipe water collection drip irrigation system

technical field

The utility model relates to the field of water collection and irrigation in sloping tea gardens, which is a self-pressure irrigation system for drought emergency by utilizing the natural drop of the sloping land of tea gardens for water collection and water collection.

Background technique

China is the world's most important tea producer, trader and consumer. According to the 2018 "Tea Blue Book", in 2017, China's tea production was 2.7292 million tons, the area of tea gardens reached 3.0549 million hectares, and the tea export was 355,300 tons. All indicators ranked among the top in the world. With a huge volume of 42.6% of global production and 23.1% of global tea exports, China has profoundly influenced and led the development of the global tea industry. Therefore, irrigating sloping tea gardens to promote the growth of tea trees, achieve high yield and quality of tea, and promote the development of the tea industry is of great significance to China's social and economic development.

The rainfall in the south is generally abundant, but the natural and geographical factors in different regions are complex, and the distribution of rainfall has both regional and seasonal differences. Regional differences and vertical changes in climate are very obvious, and dry and wet seasons are distinct. The water needed for the growth of tea trees is mainly supplied by natural precipitation. In the southern region, the rain in spring is continuous, and from July to September, intermittent high temperature and drought often appear in summer and autumn, which directly affects the growth of tea trees and the formation of high quality and high yield. In the dry season, for tea trees, not only "reap without harvest" depends on water, but "more harvest and less harvest" is also strongly constrained by water. In young tea gardens, due to the shallow root system of tea trees and weak drought resistance, tea seedlings are most likely to die due to drought, resulting in missing plants and broken rows. Due to the developed root system of tea trees, deep soil penetration, and strong drought resistance, the mature picking tea gardens are not prone to drought and death. However, in severe droughts, the old leaves on the tea trees often fall off, which affects photosynthesis and slows the growth of tea buds. The buds and leaves are small, and the paired leaves appear in advance, resulting in a decrease in the yield and quality of tea. Therefore, irrigating sloping tea gardens to increase soil water content and prevent premature damage is of great significance to improving the survival rate of tea seedlings, promoting the growth of tea trees, and achieving high yield and high quality.

In the existing tea gardens, there are many sloping fields. For the irrigation of the existing sloping tea gardens, the water supply pipeline and the irrigation pipeline are mostly connected, and the water source is transported from the low place to the root of the tea tree by means of pump pressure, or the sunshade net is used. The sunscreen is a way to avoid direct sunlight on the tea tree for a long time to reduce the evaporation of water. However, the above method not only has high cost, consumes a lot of electricity, but also increases labor costs.

The utility model utilizes the natural form drop of the sloping land of the tea garden to carry out water collection and water collection, which is beneficial to emergency irrigation during drought. The utility model collects the rainwater into the water collecting tank by arranging a water collecting pipe in the rainwater collecting area of the tea garden on the sloping land, and connects the water outlet of the water collecting tank. It is connected to the drip irrigation system of the tea garden below the height of the water collection tank, so that not only can rainwater be used for irrigation of the tea garden to achieve the purpose of saving water and reducing consumption, but also the water output of the drip irrigation system can be realized through the natural drop, which further saves energy. The whole drip irrigation system is mainly composed of water collection pipe, interception wall, filter, water collection tank, water supply and exhaust pipe, automatic drainage and sewage device, and drip irrigation system pipe network. The vertical contour line of the rainwater collection area in the concave hillside is to dig a water collection ditch, lay a special water collection pipe in the water collection ditch, and set up a horizontal interception wall every 20-30m, when the rainwater is less or the slope of the hillside is large, the rainwater can be stored , Slow down runoff, retain topsoil, and improve rainwater collection rate. The header is connected to the inlet filter. The outlet pipe is connected to the outlet filter, and the outlet pipe is connected to the drip irrigation system. The utility model adopts a special water collecting pipe, which has the advantages of good filtering and water collecting effect, anti-aging, easy installation and easy maintenance. There is an automatic drainage and sewage device in the water collection tank. When the water collection tank is full, the buoyancy of the buoy is larger than the gravity of the buoy and the inverted trapezoidal cone. The buoy drives the inverted trapezoidal cone to move up and down to open the drain. Close, complete the action of high water level drainage and low water level closing the drainage outlet, the excess water is discharged from the bottom of the collecting tank, and the sediment and other substances deposited under the collecting tank are discharged by the way, forming an automatic drainage and automatic sewage circulatory filtration system. The upper part of the water collecting tank is connected with a water supply and exhaust pipe. On the other hand, it can be used as a supplementary water pipe to ensure that external water supply can be used for automatic irrigation in dry and rainless seasons. The supplementary water pipe can also be used as an exhaust pipe during normal operation. During the collection process, the collecting pipe is exhausted when filling the collecting tank with water. The collection tank collects rainwater at elevations above the tank and irrigates the area with elevation lower than the tank. The main drip irrigation network is buried underground to ensure the beauty of the tea garden. The capillary pipes are arranged in parallel with the contour lines, and the pressure compensation drip irrigation belt is used to balance the pressure difference generated by the up and down slopes.

The working principle of the automatic drainage and sewage device: when the device works normally at low water level, the gravity of the inverted trapezoidal cone block is greater than the buoyancy of the water it receives at the beginning, and the inverted trapezoidal cone block is fitted with the inverted trapezoidal sewage outlet of the drain pipe, and the inverted trapezoidal sewage is closed. With the continuous rise of the water level in the collecting tank, the water pressure above the inverted trapezoidal cone will continue to increase, and the inverted trapezoidal cone will be tightly attached to the inverted trapezoidal sewage outlet. The rubber cushion for sealing, the inner wall of the inverted trapezoidal sewage outlet is also provided with a rubber cushion, which makes the sealing of the device better, thereby preventing the water tank from leaking. As the water level rises, the buoy floats up, and when the standard water level is reached, due to the limitation of the length of the rope between the buoy and the inverted trapezoidal cone, the volume of the water discharged by the buoy increases, and the buoyancy received by the buoy increases. When the gravity is greater than the buoy and the inverted trapezoidal cone, the buoy drives the inverted trapezoidal cone to rise through the connecting rope, thereby opening the inverted trapezoidal sewage outlet, and the water flows into the drain pipe along the inverted trapezoidal sewage outlet to be discharged. The inverted trapezoidal sewage outlet is located at the bottom of the water collection tank, with an inclination angle of 30°-40° around. When the water tank is draining, the excess water is discharged from the water collection tank, and the sediment and other substances deposited under the water collection tank are discharged by the way, forming an automatic drainage system. , Automatic sewage recycling filtration system.
