Description

'Lamp heart' type water supply garden rain collector

technical field

The invention relates to a rain-collecting and water-feeding device for urban landscaping or tree planting in arid areas.

Background technique

Moisture is the prerequisite for the survival and growth of trees in urban landscaping or afforestation in arid and less rainy areas and desert areas. People do everything possible to irrigate to meet the water demand of garden plants. According to the 2001 China Urban Construction Statistical Bulletin, the national annual urban water supply is 46.6 billion cubic meters, of which public service water (mainly landscaping water) is 5.9 billion cubic meters, It accounts for 12% of the total water supply, and the garden irrigation technology in my country is very immature at present. About 80% of the water is lost due to deep loss and ineffective evaporation. People have also invented some new water-saving irrigation technologies. Poor practicality or high cost, but not widely promoted. On the other hand, my country's current urban rainwater harvesting application techniques are not very mature, and most of them use engineering methods, which are expensive and not widely used.

Contents of the invention

The present invention provides a "wick" rain collector for water supply and landscaping, which collects surface runoff accumulation during urban rainfall, or directly collects rainwater accumulation, and then slowly releases it for use by plants when it is dry, so as to fundamentally solve the problem of urban gardening. Water for greening, or water shortage for afforestation in arid and desert areas.

The technical solution adopted in the present invention is: the present invention includes a water collection bottle and a 'wick' type water supply pipe, the water collection bottle is installed in the soil next to the base of the tree, and one end of the 'wick' type water supply pipe passes through the water collection bottle The bottle body is inserted into the bottom of the water collection bottle, and the other end is inserted into the soil in the root zone of the tree. The 'wick' type water supply pipe is made of tubular impermeable material on the outside and filled with fibrous substances with strong water absorption.

The present invention also includes a water collecting funnel and a filter net cover, the water collecting funnel is flat and slightly concave, the edge has fixing holes for fixing, and the center has a circular hole with the same size as the mouth of the water collecting bottle; The net cover is covered above the circular hole in the center of the water collecting funnel.

The present invention also includes a water inlet movable tongue, the water inlet movable tongue is installed at the mouth of the water collection bottle, and the water inlet movable tongue is a trapezoidal cylindrical shape with a wide top and a narrow bottom made of a very thin plastic film. structure, the lower part is divided into two and cut into two pieces.

The beneficial effects of the present invention are: the present invention includes a water collection bottle and a 'wick' type water supply pipe, which can collect rainwater into the water collection bottle when it rains. The strong fibrous material forms a stable capillary system in the tube. This capillary system can automatically, slowly and stably transport the rainwater collected in the water storage bottle to the soil outside when the soil is dry and water-deficient. Plants absorb it, and when there is too much moisture in the soil outside (during rain or irrigation), due to the principle of water balance movement, the water supply will be automatically turned off. This water supply method is like the "wick" of an old Chinese oil lamp, relying on infiltration. The rainwater is transported out, so it is named as the "Lamp Heart" type water supply garden rain collector; the invention also includes a water collection funnel, which is flat and funnel-shaped, and is used to collect runoff rainwater; the center of the water collection funnel has a bottle mouth Circular holes of the same size direct the collected rainwater into the water collection bottle; the present invention covers a filter net cover above the circular hole in the center of the water collection funnel to prevent blockage during water collection; the present invention installs an inlet on the mouth of the water collection bottle The movable tongue of the water outlet is a trapezoidal cylindrical structure made of a thin plastic film with a wide top and a narrow bottom. The lower part is divided into two and cut into two pieces. In this way, when it rains, the movable tongue Opened by the water flow, when it is not raining, due to the evaporation of water, a pressure is generated upwards, which can make the movable tongue close.

Compared with the prior art, the present invention has the following advantages:

1. The scope of application is very wide, whether it is in arid areas or areas with rainy seasons but uneven rainfall distribution, whether it is newly planted trees or surviving adult trees, trees or shrubs, whether it is garden plants or afforestation plants Or fruit trees can be applied. Install this rain collector next to the base of the trunk. After installing the rain collector, as long as there is a little rainfall, the water in the water collection bottle can be replenished immediately, and the ability to replenish water to the trees can be obtained to ensure that the trees grow under humid conditions for a long time. Effective against drought.

2. The water collection funnel is flat, and the area can be large or small. In arid and less rainy areas or on the ground with large surface penetration, the rainfall is too small, and it is not easy to form surface runoff. If it is in areas with large instantaneous rainfall, such as southern provinces, or in urban green areas, because the surface is cement floor, the permeability is poor, and when it rains, it is easy to form surface runoff, and the water collection speed is fast. At this time, the area of the rain collecting funnel can be smaller, even without the rain collecting funnel.

3. The 'wick' type water supply pipe uses the principle of capillary infiltration to transport water, and there is a difference in penetration at both ends of the water supply pipe, which can overcome the influence of the height difference between the water level in the water collection bottle and the soil position in the water-demanding part, without any other power. It can automatically output the water in the water collection bottle to the soil outside the bottle until the water in the bottle is exhausted, and automatically adjust the water supply speed according to the soil humidity. When the soil humidity is low, the water delivery speed is accelerated, and when the soil humidity is high, The speed of water delivery slows down. When the soil water content is very high (rainfall or irrigation), due to the existence of gravity water in the soil, the soil water potential is basically balanced with the water potential in the water storage bottle, and the water supply pipe stops water delivery, so that the tree can be guaranteed. Keep the soil around the roots moist and not waterlogged, which is very conducive to the growth and development of trees.

4. The present invention can also accurately measure the water demand of a plant in different growth and development stages and under different habitat conditions by cooperating with potting technology, so as to provide a basis for scientific irrigation of plants. This is a subject of great significance both at home and abroad.

5. The present invention has simple structure, low production cost, simple manufacturing process, and can be produced in a small plastic factory, and the installation is also very simple. A hole is dug next to the tree, a water collection bottle is placed, and a water supply pipe is connected to fill the bottle. Just water.

6. The working principle of the present invention is simple, no power is required, no energy is consumed, the water delivery pipe will not be blocked under any circumstances, and the installation is basically successful at one time without maintenance.

Detailed ways

As shown in Fig. 1 and Fig. 2, the present invention includes a water collecting funnel 1, a filter screen cover 2, a water inlet movable tongue 3, a water collecting bottle 4, a 'wick' type water supply pipe 5, and the first 4 parts are connected with each other by screws. Connect and put them on one by one during installation. Wherein water collecting funnel 1, filter screen cover 2 and these three parts of water inlet movable tongue 3 can be connected into a whole during production and processing; into the hole, the bottle mouth is flush with the ground, and then the water collecting funnel 1, the filter screen cover 2 and the movable tongue 3 of the water inlet are set on the water collecting bottle 4 bottle mouth in turn, and the side of the water collecting funnel 1 is fixed to prevent it from being blown by the wind. Blowing, or being deformed by the impact of rainwater, it will create a rain-collecting effect. 'Lamp core' formula water supply pipe 5 punches a round hole from the shoulder of water collecting bottle 4 and inserts, and the water suction port end will be inserted at the bottom of the bottle, and the water outlet end will be inserted into the tree root area, and the height is suitable with the water suction port, so that To ensure that the entire water supply process is to use the principle of capillary osmosis to supply water. Note: When installing the water collector, the water collecting funnel 1 must be slightly lower. If it is in an area with very little rainfall, a certain diversion ditch should be built around the rain collector so that the surface runoff can flow into the water collecting bottle 4 smoothly. .

Embodiment: test with three kinds of potted shrubs of False Lotus japonicus, Ficus lyre, and Rhododendron japonica, and the test method and results are as follows:

1. The height of the false lotus seedlings is 80 cm, the crown diameter is 40 cm, and the leaves are tender green. The potted plants are placed in flowerpots with specifications of 35 x 28 cm. The water collection bottle 4 is replaced by a mineral water bottle. The height of the bottom of the water bottle and the flowerpot is on the same level. , connected to the 'wick' type water supply pipe 5 (Note: In this test, the structure of the wick type water supply pipe is that the outer layer is made of transparent plastic wrap, and the inner absorbent fiber is replaced by ordinary toilet paper. The length is 85 cm, and the diameter is 1.2 cm. Of course, in actual use, the water-absorbing fiber can be made of other water-absorbing materials such as cotton fiber and flower mud for flower arrangement), watering enough water for the first time, and then no longer watering. Use a rain collector to supply water, a bottle of 500ml of water, until it is completely sucked dry, a total of 26 days of continuous water supply, and can keep the topsoil of the flower pot in a moist state (knead into a ball by hand, half broken on the ground), And corresponding control, need to water once every 2-4 days (tender leaves wither and droop are used as water demand index), and each watering is not less than 500 milliliters. In terms of the growth of saplings, the treatment was also obviously better than the control.

2. After pruning, the left seedlings are 40 cm high, 30 cm in dry diameter, 5 leaves, and the size of the flower pot is 25 x 22 cm. The operation is the same as above, and 500 ml of water is continuously supplied for 41 days.

3. Le Rhododendron, the seedling height is 60 cm, the dry branches are relatively tender, the size of the flowerpot is 35x28 cm, the operation is the same as above, and 500 ml of water is continuously supplied for 29 days. The results showed that the duration of water supply was directly related to the volume of flower pots, the total area of leaves of trees, the degree of dryness of weather and different tree species. The experimental results also preliminarily proved that designing the specifications of the rain accumulator according to the size of the tree and the longest interval of rainfall can completely overcome the influence of the arid climate in an area and ensure that the plants continue to grow under the wet conditions.
