Description

  The present invention relates to a water supply device for a plant that is used so that a flower provided for a grave or a plant for greening does not wither.

  The tomb is served with flowers in a vase, but especially during the midsummer day, the amount of water supplied by the flower is not only high, but also the water in the vase disappears due to evaporation, so that the flower quickly withers against the intention of feeding. May end up. In addition, water must be used to care for bonsai at home, but when left out for a few days, it may cause a failure to wither due to running out of water.

  Currently, greening to grow plants on the walls of buildings and rooftops is being promoted as wall greening, rooftop greening, etc., but these are places where water such as tap water can be obtained. The water is supplied to soil and sponge-like water-absorbing material where the plant is rooted. However, it is desirable for environmental beautification of the townscape if greening is performed even in places where it is difficult to use tap water, for example, in a utility pole. Also, if water can be obtained without inconvenience to plant plants in the desert, it will greatly contribute to the improvement of the global environment where desertification is a problem.

  In view of the above circumstances, the present invention maintains freshness without dying the plant without losing water even in an environment or situation where watering is difficult due to the convenience of water or the like, or normal An object was to provide a water supply device for plants that can be cultivated easily.

  In order to solve the above-described problems, the present invention provides an extraction water device having a dehumidifier structure in which a refrigerant compressor, a condenser, and an evaporator are circulated and a solar power generation device that supplies at least electric power for operating the compressor And / or a wind power generator and a water supply device for a plant, characterized by comprising a drainage pipe for distributing the dew condensation water generated in the evaporator to the plant.

  Since the water supply device for plants is configured as described above, drainage into vases with fresh flowers, flower pots with bonsai and ornamental plants, soil where plants are planted for greening, etc. If the pipe is attached with the tip attached, the extraction water device of the dehumidifier structure is activated by the electric power obtained by solar heat or wind power, and the condensed water is obtained from the air and supplied to those plants. .

  As described above, according to the present invention, water is extracted from the air by using a dehumidifier structure and supplying electric power to operate it by solar heat or wind power. Even in difficult environments and situations, there is an excellent effect that watering is not lost, for example, the freshness of the grave is kept without dying, or plants for greening can be normally grown.

  The drawing shows an embodiment, and the water supply device for the plant includes an extraction water device 1 formed by condensing water droplets from the air, a solar power generation device 3 for operating the extraction water device 1, and extracted water. It is comprised from the drainage pipe 5 which gives the water obtained with the apparatus 1 to the plant 7. FIG.

  FIG. 1 shows a case where an extraction water device 1 is provided in a housing 8 that is easy to use as a versatile type and has good ventilation, and a solar power generation device 3 is provided on the roof. 1 uses the principle of a dehumidifier, and the extraction water device 1 includes a refrigerant compressor 9 driven by power supplied from the solar power generation device 3, a next condenser 11, and a further evaporator. 13 is circulated and connected by a pipe, and an expansion valve 15 is provided between the condenser 11 and the evaporator 13. Reference numeral 16 denotes a motor that drives the compressor 9.

  According to the extraction water device 1 described above, the refrigerant of the gas such as ammonia is liquefied by being compressed by the compressor 9 and being cooled in the next condenser 11, and the expansion valve 15 is in the middle. As a result, it is vaporized by the next evaporator 13 and takes heat of vaporization from the surroundings. Here, a cooling action is performed, and the vaporized refrigerant returns to the compressor 9 to repeat this cycle. In the evaporator 13, condensation is generated on the cooled pipe or the like due to the removal of the heat of vaporization, which flows downward at regular intervals, is sent to the outside by the drain pipe 5, and is supplied to the plant 7 little by little. . In addition, since it is trace amount, it does not become excessive water supply.

  The cooling room in the upper part where the condenser 11 is placed is deeply covered with a palm-shaped roof 19, the natural wind is easy to pass through and the surroundings are almost open, and the lower room has better ventilation by the louver 22. It is. And since natural cold wind penetrates into a cooling room, it is radiated from the condenser 11 by it and cooling required for liquefaction of gas is performed. However, the wind may be forced through the cooling fan, and the power of the solar power generator 3 can be used for the operation. Moreover, it may store electricity and use electric power, and 24 indicates a storage battery in the case of such an embodiment.

  The top surface of the roof 19 is covered with a power generation panel as the solar power generation device 3, and thereby the electric power of the motor 8 that drives the compressor 9 is covered. The roof 19 is widely formed not only to cover the necessary electric power in this way, but also to shade the extraction water device 1 from solar heat. The solar heat is effectively cut off by the power generation panel, but the heat insulating material 20 is provided below to further increase the efficiency.

  Further, since the housing 8 is preferably well ventilated, it is supported by a support column 23 that can be adjusted up and down, a seat base 25 is provided at the lower end thereof, and is fixed to the installation surface 29 with screws 27 or the like.

  The water supply device P for plants as described above can be widely used for potted plants and flowers. FIG. 2 shows an example in which water is supplied to the flower vase 33 to be provided to the grave Q as the plant 7. According to this, the water supply device P for plants similar to the above is provided in the grave Q. The drainage pipe 5 is then introduced into the vase 33, and the mouth end thereof is stopped by the vase 33 with a tool (not shown).

  In FIG. 3, for the purpose of beautifying the environment, a ring-shaped flower pot 39 was fitted on the electric pole 37, a plant 7 for viewing was planted on it, and water was supplied thereto. In this case, the housing 8 including the extraction water device 1 having the same structure as the dehumidifier and having the same structure as described above is fixed to the power pole 37 by the band 41, and the solar panel of the power generation device 3 is attached to the side surface of the power pole 37. Similarly, it was fixed with a band 41. The housing 8 is provided above the flower pot 39, so that water is supplied simply by hanging down the drain pipe 5.

  FIG. 4 shows an example implemented mainly for use in desert greening. Currently, many areas are desertified in the African continent, the Middle East, and the Asian continent. Moreover, there are some areas where desertification has progressed due to weather fluctuations accompanying global warming, and in the future, desertification is rapidly progressing globally. Japan is no exception. It is said that the Amazon region is also widely deserted. In order to green the desert, it is effective to stop the evaporation of moisture from the ground by planting the plant, and to increase the amount of water retained in the soil to such an extent that the plant will naturally sprout. There have been many successful cases. However, even a plant that is resistant to drying is rooted in the first place because it is a dry land.

  The water supply device P shown in FIG. 4 generates power by combining wind power generation and solar power generation, extracts the moisture in the air with the electric power, and supplies it to the plant 7 planted in the desert. Indicated.

  Since the device is temporary until the plant grows to a full size, the column 43 is erected by simple pile driving, the weakness of the ground is reinforced by the gantry 45, and the water tank 47 is placed on the gantry 45. And a housing 8 in which the extraction water device 1 having a dehumidifier structure is built. A wind power generator 4 with a propeller 49 is provided at the upper end portion of the support column 43, and the solar power generator 3 is provided at the lower end portion.

  In the desert, it is dry during the day and is not suitable for extracting moisture from the air. Therefore, the dehumidifier is operated at night when the humidity is high, and the water is stored in the water tank 47. Therefore, in addition to the water tank 47, the storage battery 49 is essential. In addition, when water is applied to the plant 7 during the day, root rot is caused by going up with a straw so that the water is sprayed from the evening when the desert sand is cooled to dawn. In this way, nighttime watering work is performed without human intervention.
