Detailed implementation mode

[0027] To clearly illustrate the technical features of this patent, the following will elaborate on this patent in detail through specific implementation modes and in conjunction with its attached drawings.

[0028] The wind - energy street lamp includes an illumination system and a wind - power generation system. The illumination system includes a base 1, a lamp post 2 connected in sequence, and a lighting lamp 4 fixedly connected to the top of the lamp post 2 through a mounting bracket 3. The wind - power generation system includes a wind wheel 5, a generator 6, and a storage battery 7. The generator 6 and the storage battery 7 are fixedly connected to the lamp post 2. The wind wheel 5 is rotatably connected to the top of the lamp post and is connected to the rotating shaft of the generator 6. The generator 6 is connected to the storage battery 7, and the lighting lamp 4 is also connected to the storage battery 7. By driving the rotation of the rotating shaft of the generator 6 through the wind wheel 5, electric energy is collected, and power is supplied to the lighting lamp and components that require electric energy such as the refrigeration component controller, refrigeration component, valve, valve controller, temperature - humidity adjustment device, thermometer, soil moisture monitor, water level alarm, etc. in the following.

[0029] The lighting lamp 4 is an "optical - control octagonal pyramid - shaped" intelligent street lamp. There are 4 street lamps on each lamp post. An optical - control switch is arranged inside the street lamp. During the day, the street lamp automatically turns off, and at night, it automatically turns on.

[0030] The plant cultivation system includes a refrigeration and liquefaction system, a spray and drip irrigation system, and a plant cultivation system installed on the wind - energy street lamp;

[0031] The refrigeration and liquefaction system includes a refrigeration component controller 8, a refrigeration component 16, a water - collecting funnel 17, a water - conveying pipeline 9, and a water storage tank 14. The refrigeration component controller 8 is fixedly connected to the lamp post 2. The water - collecting funnel 17 is fixedly connected to the hollow mounting bracket 3 and is communicated with the top opening of the mounting bracket 3. The refrigeration component 16 is fixedly connected in the water - collecting funnel 17 and is connected to the refrigeration component controller 8. The bottom opening of the mounting bracket 3 is kept in communication with the water storage tank 14 below it through the water - conveying pipeline 9. The water storage tank 14 is fixedly connected to the lamp post 2. In this way, through conventional refrigeration components in the prior art, air can be continuously condensed, and the condensed water can be sent into the "conical" water storage tank through the water - collecting funnel and the water - conveying pipeline for temporary storage.

[0032] The plant cultivation system includes a plant cultivation box 18, in which an annular plant cultivation tank 20 is placed. A thermometer 22 and a temperature and humidity adjustment device 24 are also provided in the plant cultivation box 18. An annular drip irrigation water tank 27 is arranged on the plant cultivation tank 20, and water leakage holes 28 are arranged at the bottom of the drip irrigation water tank 27.

The controller of the temperature and humidity adjustment device 24 is connected to the thermometer 22 and the soil moisture monitor 25. In this way, after receiving the data from the thermometer 22 and the soil moisture monitor 25, the controller of the temperature and humidity adjustment device 24 heats, cools or dehumidifies the environment in the plant cultivation box 18, so as to adjust the environmental temperature in the cultivation box to a predetermined range before drip irrigation, and maintain the environmental temperature during drip irrigation. And after the plants are placed, the humidity of the cultivation soil can be reduced by dehumidification to avoid excessive humidity of the cultivation soil, which is not suitable for plant growth. As for the humidification of the soil, it needs to be carried out in cooperation with drip irrigation. Among them, since the temperature and humidity adjustment device is very common in the prior art, the specific structure thereof will not be described in detail in this case.

[0033] The spray and drip irrigation system includes a drip irrigation pipe 12 arranged above the plant cultivation tank 20 and communicating with the reservoir 14. A valve is provided in the drip irrigation pipe 12, a flow rate controller is provided in the drip irrigation pipe 12, a drip irrigation nozzle 19 is provided at the bottom opening of the drip irrigation pipe 12, and a valve controller 11 for controlling the valve is fixedly connected to the drip irrigation pipe 12. The valve controller 11 is also connected to the soil moisture monitor 25. In this way, after plants are planted under the drip irrigation nozzle, they can be irrigated by drip irrigation, and through the following temperature and humidity adjustment device, they can be in a good growth environment, so as to utilize the wind energy street lamp water for irrigation and carry out the cultivation of plant suitable varieties, overcoming the problem of difficult plant cultivation in high altitude rocky desert areas.

[0034] A water level alarm 10 and a spray pipe 15 are also provided in the reservoir 14. The top opening of the spray pipe 15 is kept communicating with the top of the reservoir 14. Thus, when the water level in the reservoir is too high, an alarm is issued through the water level alarm, and overflow is carried out by means of the spray pipe to irrigate the plants near the lamp post.

[0035] The plant cultivation box 18 is connected to the lamp post 2 through a mounting seat 13. The mounting seat 13 is detachably sleeved on the lamp post 2, and a supporting platform is provided at the bottom of the mounting seat 13. The plant cultivation box 18 is sleeved on the mounting seat 13 and placed on the supporting platform.

[0036] A plant cultivation box cover plate 23 is provided at the top of the plant cultivation box 18, and a through hole for passing through the drip irrigation pipe 12 is opened on the plant cultivation box cover plate 23. Thus, after the mounting seat 13 is disassembled, the plants can be conveniently taken and placed.

[0037] The bottom of the plant incubator 18 is also covered with heat-insulating cotton, thus playing a good heat-insulating role.

[0038] Implementation case: A certain mine is located in a rocky desert mining area at a high altitude in the west. In recent years, coal mining has caused ecological damage phenomena such as surface subsidence and vegetation withering. After on-site investigation, the surface of this mining area is mainly covered with vegetation that grows well. For the restoration of the subsidence area, a plant cultivation system and method using a wind energy street lamp for water collection and irrigation in a high-altitude rocky desert area are used to cultivate plant seedlings.

According to the investigation results, obtain the seeds of Caragana korshinskii, Glycyrrhiza uralensis, Oxytropis aciphylla, and Astragalus adsurgens to be cultivated, configure the culture soil in a plant culture dish, and use numerical simulation experiments to obtain that the suitable soil moisture contents for the growth of Caragana korshinskii, Glycyrrhiza uralensis, Oxytropis aciphylla, and Astragalus adsurgens are 50% - 55%, 36% - 44%, 48% - 55%, and 60% - 77% respectively; the suitable temperature is set at 23 - 26 °C;

[0040] S2. Install the lighting system, wind power generation system, refrigeration and liquefaction system, sprinkler and drip irrigation system, and plant cultivation system in sequence by the roadside;

[0041] S3. Start the wind power generation device, and turn on the refrigeration and liquefaction system and the sprinkler and drip irrigation system;
