Green wall watering system

The present invention relates to a green wall watering system, in particular to a green wall watering system in which a plurality of pots can be placed adjacent to each other up and down to utilize a plant to beautify the wall surface.

In order to beautify the home environment, office buildings, residential communities, public places, etc., there are many green wall designs, mainly to set up a green wall device on the wall of the building. The green wall device includes several basins that are adjacent to each other. The basins are arranged in a row in groups, so that there are several rows of pots arranged up and down. Each pot can be placed in a pot to form an upright and large area of green decorative wall. When watering the pot, the water is connected to the uppermost pot through a water supply pipe. When the water is poured into the upper row of the pots, the water can flow from the bottom of the upper pot to the lower pot. To achieve the purpose of drip irrigation.

In the past, the method of drip irrigation was carried out at regular intervals. At every fixed time, the water supply pipe provided water to the pots and pots. However, under what circumstances, the plants need to be watered, in fact, with the plant growth environment, Climate-related, such as the length of time the sun shines, the intensity of sunlight, ambient temperature, humidity, and so on. When the sun shines for a long time, the water is easy to evaporate. At this time, it is necessary to water more frequently. When the ambient humidity is high and the sunlight is low, the number of watering can be reduced. Therefore, in fact, the conventional method of using timed drip irrigation cannot meet the plant's demand for moisture, and the green wall device needs to be improved.

Therefore, the object of the present invention is to provide a green wall watering system that can provide water according to the needs of plants and grow plants well.

Thus, the novel green wall watering system is adapted to connect a water source and includes a basin unit, a buoyancy valve, and a pressure reducing valve.

The buoyancy valve is disposed on the tested basin and connected to the water supply pipe, the buoyancy valve is configured to detect the water level of the tested basin, and can control the water level of the tested basin when the water level of the tested basin is lower than a standard water level The water supply pipe supplies water to the basin and the tested basin, and when the water level of the tested basin is equal to or higher than the standard water level, the water supply pipe is controlled to stop the water supply. The pressure reducing valve is connected between the water source, the buoyancy valve and the water supply pipe, and is used to reduce the water pressure of the water source, and then pass the water and enter the water supply pipe.

The effect of the novel is to control whether the water supply pipe is filled with water by the buoyancy valve, drip irrigation when needed, stop the water supply when it is not needed, and provide water according to the needs of the plant, so that the plant grows well. Further, the pressure reducing valve is firstly used to reduce the water pressure of the water source and then inject the water into the water supply pipe, thereby protecting the buoyancy valve, prolonging the life of the component of the buoyancy valve, and making the buoyancy valve operate smoothly.

The basins 11 of the present example are arranged in a plurality of rows in a plurality of rows, and the accommodating spaces 110 of the basins 11 of the same row are in communication with each other. The connecting tubes 12 are two or two sets, and the connecting tubes 12 of the two groups are respectively located at the left and right sides of each of the rows of pots 11, and the connecting tubes 12 are used for making the same row of the pots 11 Water can flow into the lower row of the basins 11 via the communication tube 12. The tested basin 13 is located at the lowermost right corner of the basin unit 1, and is disposed at the most downstream position among the basins 11 mainly according to the flow direction of the water. The water supply pipe 14 extends laterally rightward from the lower portion of the basin unit 1 and then extends upwardly above the uppermost row of the basins 11. The water supply pipe 14 includes a water inlet 141 that connects the buoyancy valve 2, and a water outlet 142 that communicates with one of the basins 11 of the basin 11 (the basin 11 at the uppermost left corner).

The buoyancy valve 2 is disposed on the side of the tested basin 13 and connected to the water supply pipe 14 and used to detect the water level of the tested basin 13 to control the amount of water entering the water supply pipe 14. The buoyancy valve 2 includes a floating block 21 located in the tested basin 13 and capable of being floated by the buoyancy of water in the tested basin 13 , spaced apart below the floating block 21 and capable of being driven And an actuating rod 22 moving up and down and located above the water inlet 141 of the water supply pipe 14, a valve body 23 coupled to the bottom of the actuating rod 22 and adjacent to the water inlet 141, one below the floating block 21 and used for The actuating rod 22 is biased downwardly against the resilient abutting member 24, a first magnetic member 25 that is operatively mounted to the bottom of the floating block 21, and one of the actuating rods 22 and the first magnetic member 25 The magnetic attraction attracts the second magnetic member 26. The bottom section of the elastic abutting member 24 is fixed to the actuating lever 22, and the top section is pressed against the bottom wall of the tested basin 13.

The pressure reducing valve 3 is connected between the water source 5, the buoyancy valve 2 and the water supply pipe 14, and is used to reduce the water pressure of the water source 5, and then allow water to enter the water supply pipe 14. The pressure reducing valve 3 includes a pressure reducing pipe 31 that is upright and defines a decompression space 310, a valve shaft 32 that is vertically movably disposed in the decompression space 310, and one for lowering the valve shaft 32 downward. The elastic member 33 is pushed, and a sealing ring 34 is looped over the valve shaft 32. The decompression tube 31 includes an inlet 311 for injecting water from the water source 5 and communicating with the decompression space 310, and an outlet 312 communicating the decompression space 310 with the water supply pipe 14. The inlet 311 has a first end 313 that connects the water source 5, and a second end 314 that connects the reduced pressure space 310 and is smaller in size than the first end 313.

The fertilizer applicator 4 can be connected to the water supply pipe 14 and used to provide fertilizer. The fertilizer can be injected into the fertilizer applicator 4, and then mixed with water and injected into the basin 11. The implementation of the present invention is not necessary to provide the fertilizer applicator 4, and the installation position of the fertilizer applicator 4 is not limited.

Referring to Figures 2, 3 and 4, in the present invention, the basins 11 can respectively accommodate a pot, and the water of the water source 5 can pass through the pressure reducing valve 3 and enter the water supply pipe 14, the water of the water supply pipe 14 The water pipes 142 are flowed into the uppermost rows of the basins 11, and the water pipes in the plurality of basins 11 in the upper row are provided via the communication pipes 12 on the left and right sides of each of the basins 142. The communicating tubes 12 are injected downward into the plurality of pots 11 of the lower row to drip the pots in the respective pots 11. After the fertilizer of the fertilizer applicator 4 is mixed with water, it can flow into the pots 11 in the same path to fertilize the plants. It should be noted that when the communication tubes 12 are not in use, the openings may be plugged by a plug body (not shown).

The buoyant valve 2 of the present invention can control whether or not drip irrigation is performed according to the environment and climate of the plant according to the needs of the plant. The main principle is that because the length of the sun exposure, the size of the sun, the temperature of the environment, the humidity, etc., will affect the evaporation of the water of the plant, and the height of the water in each pot 11 will be affected by the above-mentioned plant growth environment and climate. The effect, for example, when the sun shines for a long time, whether the water in the plant or the pot 11 is easily evaporated, the water level of the pot 11 is low, which means that the plant needs to be watered. In contrast, when the ambient humidity is high and the sunlight is low, the water in the basin 11 is less evaporated, which means that the water of the plant is still sufficient, and watering is not required, so that the water level of the basin 11 can be detected. Control whether drip irrigation is performed. Further, since the basins 11 are in communication with the water path of the basin under test 13, the water level of the basins 13 to be measured can be measured to represent the water level of all the basins 11.

Specifically, the buoyancy valve 2 can control the water supply pipe 14 to supply water to the basin 11 and the tested basin 13 when the water level of the tested basin 13 is lower than a standard water level, and at the test When the water level of the basin 13 is equal to or higher than the standard water level, the water supply pipe 14 is controlled to stop supplying water to the basins 11 and the tested basins 13. When the water level of the tested basin 13 is equal to or higher than the standard water level (as shown in the first flow of FIG. 4), it indicates that the amount of water in each of the basins 11 is sufficient, and the actuating rod 22 is biased by the elastic pushing member 24. The first magnetic member 25 is far away from the second magnetic member 26, so that it does not attract, and the valve body 23 blocks and blocks the water inlet 141 of the water supply pipe 14 to make the water source 5 Water does not flow into the water supply pipe 14, and drip irrigation is not performed at this time. As shown in the second flow of Fig. 4, when the water level of the tested basin 13 is lower than the standard water level, it means that the water level in each pot 11 is also low, and the potted plants are relatively short of water. At this time, the floating block 21 The position of the first magnetic member 25 and the second magnetic member 26 become smaller as the water level becomes lower, and the magnetic attraction between them is resistant to the force of the elastic abutting member 24 to push down the actuating rod 22 downward. And then the actuating rod 22 is attracted upwardly, the valve body 23 moves upwards and no longer blocks the water inlet 141, and the water of the water source 5 can enter the water supply pipe 14 from the water inlet 141 for drip irrigation. Watering.

Subsequently, when the water level of the tested basin 13 returns to a higher water level state, the floating block 21 rises back to the position of the first flow of FIG. 4, and the actuating rod 22 is further biased downward by the elastic abutting member 24. Pushing, the valve body 23 is lowered to re-block the water inlet 141 of the water supply pipe 14, and by such a cycle, the water supply or the water supply can be automatically controlled.

Referring to Figures 3 and 5, it is worth mentioning that the present invention is further provided with the pressure reducing valve 3, the decompression action is as follows: the valve shaft 32 can be in a non-decompression position as shown in the first flow of Figure 5 And a movement between the decompression positions as shown in the second flow of Fig. 5. When the water source 5 is not supplied with water or the water pressure of the water supply is low, the valve shaft 32 is located at the non-decompression position. When the water source 5 supplies water, since the second end portion 314 of the inlet 311 of the decompression tube 31 is smaller in size than the first end portion 313, water flows from the first end portion 313 to the second end portion 314. A large pressure water flow is formed and injected into the decompression space 310. The water pressure pushes the elastic member 33 upward, and the elastic member 33 drives the valve shaft 32 to move upward to the decompressing position. The sealing ring 34 Cooperating with the valve shaft 32, blocking a portion of the outlet 312 in the decompressed position, and shielding from the center to the upper side of the outlet 312 to limit the amount of water discharged from the outlet 312, so that the amount of water entering the water supply pipe 14 is compared. It is small and the water pressure is also low, so that a large amount of water is directly injected into the water supply pipe 14, so that the buoyant valve 2 can be prevented from being affected by excessive water inflow, the buoyancy valve 2 can be prevented from being damaged, and the buoyancy can be avoided. The component moves in the valve 2, detects the water level accuracy and the switch state.

In summary, the present invention provides the buoyancy valve 2 to control whether the water supply pipe 14 is filled with water, drip irrigation when needed, stop the water supply when it is not needed, and provide water according to the plant demand, so that the plant grows. good. Further, the pressure reducing valve 3 is used to first reduce the water pressure of the water source 5 and then inject the water into the water supply pipe 14, so that high pressure can be avoided and a large amount of water directly impacts the buoyancy valve 2, so the pressure reducing valve 3 is designed to protect the The buoyancy valve 2 can extend the life of the element of the buoyancy valve 2 and allow the buoyancy valve 2 to smoothly perform the switching operation.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
