Description

Technical Field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a luminous plant protection device in an agricultural facility. Background Art

[0002] There are two main types of pests encountered in crop production, namely diseases and insect pests. The main solution is to use pesticides to kill them, but the side effect of pesticide use is residues. In order to avoid or use less pesticides, natural enemies can be used to kill and inhibit pests, for example, sticky boards are used in agricultural facilities to kill insects, but physical sterilization is a difficult problem in agriculture.

[0003] At present, most of the pesticides on the market use spectral sterilization, virus killing and insecticide. Because the amount of pesticides used is large and they must be used continuously, pests and diseases will reappear once the pesticides are stopped. The long-term use of pesticides will lead to the problem of pesticide residues. In addition, pesticides are generally used for sterilization, and many pesticides are used only after the bacteria are found; often the bacteria are killed, and the toxins left on the leaves and stems cannot be removed, which will also affect the yield and quality of the plants.

[0004] Some existing technologies use deep ultraviolet radiation to destroy pathogen spores and inhibit pathogen replication, which can achieve the purpose of eliminating pathogens. However, ultraviolet rays can cause DNA chain breaks, and ultraviolet rays reaching a certain intensity are also harmful to plants, and may even cause plant mutations and directly kill organisms. Summary of the invention

[0005] In response to at least one of the problems in the above-mentioned prior art, the purpose of the present invention is to provide a luminous plant protection device in agricultural facilities, which can not only kill pathogens but also protect plants from being damaged by ultraviolet rays; and reduce the risk of pesticide residues, which is conducive to ensuring plant yield and quality.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A luminous plant protection device in an agricultural facility, comprising: Ultraviolet lamps are used to emit ultraviolet light to irradiate plants and kill pathogens; An infrared lamp is arranged in combination with the ultraviolet lamp; the infrared lamp is used to emit infrared light, and the infrared light forms a protective halo on the surface of the plant to reduce the damage of the ultraviolet light to the plant.

[0007] Preferably, the ultraviolet lamp and the infrared lamp are both installed on the par lamp body.

[0008] Preferably, the par light body is connected to a rope; the rope is arranged in a ring shape and is tensioned on the driving wheel and the driven wheel; the driving wheel is coaxially connected with the rotating output shaft of the reduction motor, the reduction motor is used to drive the driving wheel to rotate, the driving wheel is used to drive the driven wheel to rotate, and the rope forms a transmission mechanism to drive the par light body to move.

[0009] Preferably, the par lamp body is provided with an inverted cone-shaped lampshade.

[0010] Preferably, the number of the ultraviolet lamps and the number of the infrared lamps are at least two and are evenly spaced.

[0011] Preferably, the luminous power of the ultraviolet lamp accounts for 28% of the total luminous power of the luminous plant protection device, and the luminous power of the infrared lamp accounts for 72% of the total luminous power of the luminous plant protection device.

[0012] Preferably, the ultraviolet lamp and the infrared lamp are both connected to a time-controlled switch, and the time-controlled switch is used to control the timing on and off of the ultraviolet lamp and the infrared lamp.

[0013] Preferably, a display screen is provided on the time-controlled switch.

[0014] Preferably, a control button is provided on the time control switch.

[0015] Preferably, a warning light power line is provided on the time-controlled switch, and the warning light power line is connected to the warning light.

[0016] The present invention adopts the above technical solution, which has the following advantages: 1. The luminous plant protection device in the agricultural facilities provided by the present invention uses ultraviolet radiation to protect plants and prevent diseases. It is a physical plant protection method that can kill bacteria and viruses, and can disable the feeding system of insects, thereby killing pests; it can also use infrared lamps to form halos on plant leaves and stems, thereby protecting plants and preventing them from being harmed by ultraviolet rays; at the same time, since deep ultraviolet light sources are relatively expensive, densely arranging ultraviolet lamps will cause waste, and combining infrared lamps with ultraviolet lamps can reduce costs; the luminous plant protection device can be widely used in agricultural facilities, such as in closed and semi-closed greenhouses and plant production workshops, with very good effects; it can greatly reduce the use of pesticides, reduce the risk of pesticide residues, and avoid pollution of the surrounding environment.

[0017] 2. Generally, pesticides are used for sterilization. In many cases, pesticides are used only after the bacteria are found. Often, the bacteria are killed, but the toxins remaining on the leaves and stems cannot be removed, which will also affect the yield and quality of the plants. The luminous plant protection device in the agricultural facilities provided by the present invention is conducive to ensuring the yield and quality of the plants and increasing the yield. For example, by lighting the lights for a short period of time every day, it can play a preventive role and allow the plants to grow healthily.

[0018] 3. The luminous plant protection device in the agricultural facilities provided by the present invention can use LED lamp beads as ultraviolet and infrared light sources, which is conducive to the accurate selection of special wavelengths, can increase the life of the lamp, reduce power consumption, and improve efficiency; it only needs a short period of irradiation every day to achieve disease prevention and sterilization effects, which is beneficial to the healthy growth of plants.

[0019] 4. The luminous plant protection device in the agricultural facilities provided by the present invention can control the movement of the lamp on the rope through a reduction motor, or multiple lamps can be arranged on the rope for controlled movement, thereby covering a larger range of disease and pest control to kill germs and bacteria, and is beneficial to reducing the number of ultraviolet lamps used, reducing costs, and ensuring the use effect.

By combining ultraviolet lamps and infrared lamps, the device can kill pathogens by ultraviolet rays and protect plants by infrared rays, thereby preventing the plants from being harmed by ultraviolet rays. The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1 Please refer to Figure 1 The luminous plant protection device in the agricultural facility provided in this embodiment includes an ultraviolet lamp 1 and an infrared lamp 2. The ultraviolet lamp 1 is used to emit ultraviolet light to radiate and kill pathogens on plants; the infrared lamp 2 is arranged in combination with the ultraviolet lamp 1; the infrared lamp 2 is used to emit infrared light, and the infrared light forms a protective halo on the surface of the plant to reduce the damage of ultraviolet light to the plant.

[0028] The luminous plant protection device in the agricultural facility of this embodiment combines the ultraviolet lamp 1 and the infrared lamp 2, which can be used to irradiate the plants. The ultraviolet light emitted by the ultraviolet lamp 1 can kill the germs of the plants and also disable the feeding system of insects; and the infrared light emitted by the infrared lamp 2 can protect the plants and reduce or even prevent the plants from being damaged by ultraviolet rays. The luminous plant protection device in the agricultural facility can be set in multiple numbers and can be arranged in multiple groups.

[0029] Wherein, both the ultraviolet lamp 1 and the infrared lamp 2 can adopt LED light sources, and the wavelength can be accurately selected. The LED light source can include a circuit board and at least two LED lamp beads arranged on the circuit board, and the LED lamp beads include LED ultraviolet lamp beads and LED infrared lamp beads, thereby forming a lamp combining an ultraviolet light source and an infrared light source. The distance between adjacent LED lamp beads can be equal. The voltage of the LED light source can be 47V or 48V.

[0030] The LED lamp beads include at least one LED ultraviolet lamp bead with a peak wavelength of 280nm and at least one LED infrared lamp bead with a peak wavelength of 620nm. The ultraviolet light with a wavelength of 280nm is effective in killing bacteria, viruses and insects, and the infrared light with a wavelength of 620nm can protect plant tissues.

[0031] The luminous power of LED infrared lamp beads can be three times that of LED ultraviolet lamp beads, and LED infrared lamp beads and LED ultraviolet lamp beads are evenly spaced.

[0032] Specifically, the ultraviolet lamp 1 and the infrared lamp 2 are both mounted on the par lamp body 3 to form a par lamp. The lamp body shell can be composed of metal and quartz glass, which can prevent ultraviolet light from corroding its materials.

[0033] Among them, a rope 6 can be stretched above the plant, and the par light can be connected to the rope 6. For example, the par light is connected to the rope 6 by a screw lock. The rope 6 can be made of steel wire.

[0034] Please refer to Figure 1 and Figure 2 Specifically, the par light body 3 is connected to the rope 6; the rope 6 is set in a ring shape and is tensioned on the driving wheel 501 and the driven wheel 502. The driving wheel 501 is coaxially connected with the rotating output shaft of the reduction motor 4. The reduction motor 4 is used to drive the driving wheel 501 to rotate, and the driven wheel 502 can be rotatably installed on the support rod. The driving wheel 501 drives the driven wheel 502 to rotate through the rope 6, and the rope 6 forms a transmission mechanism to drive the par light body 3 to move.

[0035] For example, the reduction motor 4 controls the lamp to move horizontally in the east-west or north-south direction, and the moving distance of a single lamp can be 10m, 20m or even farther to cover a larger pest and disease prevention range.

[0036] Please refer to Figure 1 Specifically, the par light can have a focusing function, and the par light body 3 is provided with an inverted cone-shaped lampshade 7.

[0037] Specifically, at least two ultraviolet lamps 1 and infrared lamps 2 are respectively provided and evenly spaced.

[0038] Specifically, the luminous power of the ultraviolet lamp 1 accounts for 28% of the total luminous power of the luminous plant protection device, and the luminous power of the infrared lamp 2 accounts for 72% of the total luminous power of the luminous plant protection device.

[0039] Please refer to Figures 1 to 3Specifically, the ultraviolet lamp 1 and the infrared lamp 2 are both connected to the timer switch 8, which is used to control the timing on and off of the ultraviolet lamp 1 and the infrared lamp 2, that is, the on and off time of the lamp can be set by the timer switch 8. The timer switch 8 can adopt the timer switch device of the prior art.

[0040] Specifically, a display screen 9 is provided on the time control switch 8, and parameters such as the timing time can be displayed through the display screen 9.

When the luminous plant protection device is working, the warning light lights up or flashes, and the warning personnel turn off the luminous plant protection device before entering the agricultural facility, thereby avoiding the harm of ultraviolet light with a peak wavelength of 280nm to the human body. The warning light can adopt existing technology products.

[0043] The time switch 8 is provided with a lamp power line 12 for connecting the lamp. The time switch 8 is provided with a reduction motor power line 13 for connecting the reduction motor 4.
