Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a fixing frame for supplemental lighting in greenhouses with adjustable light angle. Background Technology

[0002] In the current era of booming modern agriculture, greenhouses, as facilities that can effectively resist adverse climatic conditions and create a suitable environment for plant growth, are widely used in the cultivation of various crops. Light, as a key environmental factor affecting plant growth and development, plays a decisive role in many important physiological processes such as photosynthesis, morphogenesis, flowering, and fruiting. To solve the problem of lighting in greenhouses, supplemental lighting has become an important auxiliary means. The performance of the supplemental lighting bracket, as the support and adjustment device for the supplemental lighting, directly affects the supplemental lighting effect.

[0003] The existing grow light fixtures have a single angle, which may cause plants to receive different light intensities from the front and back or left and right, thus affecting their positioning and potentially leading to abnormal growth and development. Utility Model Content

[0004] To solve the above problems, this utility model provides a fixing frame for supplemental lighting in planting greenhouses with adjustable light angle.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable light angle supplemental lighting fixture for a planting greenhouse, comprising a greenhouse fixing base, a folding bracket body, and a supplemental lighting fixture. The folding bracket body is connected to the bottom of the greenhouse fixing base via a rotating shaft. The supplemental lighting fixture is connected to the folding bracket body via a rotating shaft. The folding bracket body is composed of two support rods that are hinged together in sequence. A rotating shaft is provided at the hinge point of the two support rods. A drive motor is fixedly installed at the end of each of the multiple rotating shafts.

[0006] By adopting the above technical solution, the drive motor can precisely control the rotation of each shaft, thereby flexibly adjusting the angle between each section of the support rod of the folding bracket body, as well as the angle of the supplementary light fixture relative to the folding bracket body. This allows the supplementary light to provide supplementary lighting to crops in the greenhouse at any desired angle, greatly improving the accuracy and flexibility of supplementary lighting and meeting the diverse needs of different crops for light angle at different growth stages.

[0007] Furthermore, the side surface of the fill light fixture is provided with a slot, a magnetic ring is engaged inside the slot, and a spacer ring is provided inside the slot on the outer side of the magnetic ring, and the spacer ring and the slot are filled with sealant.

[0008] By adopting the above technical solution, the magnetic adsorption effect of the magnetic ring is used to adsorb some of the supplementary lighting components with metal materials. The components are initially fixed by magnetic adsorption, eliminating the need for workers to lift them. This facilitates the subsequent fixing and installation of the supplementary lighting components with bolts, significantly improving installation efficiency.

[0009] Furthermore, the drive motor is equipped with an electromagnetic lock.

[0010] By adopting the above technical solution, once the drive motor has adjusted the angle of the supplementary light, the electromagnetic lock can work quickly to lock the relative position of the drive motor output shaft and the damping shaft, preventing the supplementary light angle from shifting due to external force collisions, vibrations, or other factors, and ensuring that the supplementary light always provides continuous supplementary light to the crops at the set precise angle, maintaining a stable supplementary light effect.

[0011] Furthermore, the surfaces of the greenhouse fixing base, the folding bracket body, and the supplementary lighting fixing base are all provided with an anti-corrosion coating, and the anti-corrosion coating is a galvanized layer.

[0012] By adopting the above technical solution, the galvanized layer has good anti-corrosion performance, which can effectively resist the corrosive environment of high humidity, acid and alkali in the greenhouse, prevent the greenhouse fixing base, the main body of the folding bracket and the fixing base of the supplementary light from rusting and corroding, extend the overall service life of the fixing frame, reduce maintenance costs, and ensure the long-term stable operation of the fixing frame.

[0013] Furthermore, the magnetic ring is made of high-temperature resistant neodymium iron boron material.

[0014] By adopting the above technical solution, the high-temperature resistant neodymium iron boron magnetic ring can still maintain stable magnetism in the high-temperature environment inside the greenhouse. The magnetism will not be greatly weakened due to the increase in temperature. This ensures that the magnetic ring's adsorption and fixation of the supplementary light is not affected in hot weather or in high-temperature scenarios such as near supplementary lights with high heat generation, thus maintaining the stability of the supplementary light installation.

[0015] Furthermore, the greenhouse mounting base has an internal cavity, and a microcontroller and a wireless connection unit are installed inside the cavity. The microcontroller and the wireless connection unit are electrically connected, and the wireless connection unit is a WiFi 6 module.

[0016] By adopting the above technical solution, the WiFi 6 module has high-speed, low-latency, and high-stability wireless data transmission capabilities. It can receive control commands from external devices such as mobile phones, computers, and greenhouse intelligent control systems in real time and quickly transmit them to the microcontroller. Based on the received commands, the microcontroller precisely controls the forward and reverse rotation and speed of the drive motor, as well as the locking and unlocking of the electromagnetic lock, realizing convenient remote adjustment of the angle of the supplementary lighting fixture and improving the intelligence and convenience of operation.

[0017] In summary, this utility model has the following beneficial effects: 1. In this application, the drive motor can precisely control the rotation of each shaft, thereby flexibly adjusting the angle between each section of the support rod of the folding bracket body, as well as the angle of the supplementary light fixture relative to the folding bracket body, so that the supplementary light can provide supplementary light to the crops in the greenhouse at any required angle, greatly improving the accuracy and flexibility of supplementary light, and meeting the diverse needs of different crops for light angle at different growth stages. 2. In this application, the magnetic adsorption effect of the magnetic ring is used to adsorb some of the supplementary lighting components with metal materials. The magnetic adsorption is used for initial fixation, eliminating the need for workers to lift it. This facilitates the subsequent fixation and installation of the supplementary lighting components with bolts, significantly improving installation efficiency. The sealant filled between the spacer ring and the slot provides a good seal, preventing moisture, dust and other impurities in the greenhouse from entering the slot and affecting the performance of the magnetic ring and the fixation effect of the supplementary lighting, thus extending its service life.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] like Figure 1-3 As shown in the figure, this application discloses an adjustable light angle supplemental lighting fixture for a greenhouse, including a greenhouse mounting base 1, a folding bracket body 2, and a supplemental lighting fixture 3. The folding bracket body 2 is connected to the bottom of the greenhouse mounting base 1 via a pivot, and the supplemental lighting fixture 3 is connected to the folding bracket body 2 via a pivot. The folding bracket body 2 is composed of two support rods 4 that are hinged together in sequence. A pivot is provided at the hinge of the two support rods 4, and a drive motor 5 is fixedly installed at the end of each of the multiple pivots.

[0022] Greenhouse Fixing Base 1: Greenhouse Fixing Base 1 is the foundational load-bearing component of the overall structure. Its bottom has expansion bolt holes, which are then rigidly connected to the greenhouse beams or columns via bolts, ensuring the overall stability of the fixing frame. The fixing base has an internal cavity with a removable cover plate at the cavity opening, facilitating the installation of the microcontroller 10 and the wireless connection unit 9. Serving as the "foundation" of the entire fixing frame, it stably secures the equipment to the greenhouse structure while providing protective installation space for the electrical control unit, preventing interference from the external environment.

[0023] Folding support body 2: The folding support body 2 consists of two support rods 4. The top of the first support rod 4 is connected to the greenhouse fixing base 1 through a damping pivot, and the bottom is hinged to the second support rod 4 through another set of coaxial damping pivots. The support rods 4 are made of hollow aluminum alloy, and the connection cable between the drive motor 5 and the control unit is run through the inside. The hinge structure of the two support rods 4 realizes "folding and storage" and "multi-angle adjustment": In the non-working state, the two support rods 4 can be folded to a close-fitting state to save greenhouse space; in the working state, the drive motor 5 drives the pivot to rotate, realizing the adjustment of the supplemental light at any angle in the horizontal and vertical directions, accurately matching the crop's light requirements.

[0024] The side surface of the fill light mounting base 3 is provided with a slot, the inside of which a magnetic ring 7 is engaged, and a spacer ring 8 is provided inside the slot on the outer side of the magnetic ring 7, and the spacer ring 8 and the slot are filled with sealant.

[0025] Fill light base: The back of the fill light mounting base 3 is hinged to the end of the second support rod 4 of the folding bracket body 2 via a damping pivot. The pivot axis is parallel to the pivot axis between the two support rods 4. An annular groove is opened on the side surface of the mounting base. The inner side of the groove is fitted with a magnetic ring 7 by an interference fit. A spacer ring 8 is fitted on the outer side of the magnetic ring 7 (the gap between the spacer ring 8 and the inner wall of the groove is filled with sealant to achieve moisture-proof sealing). As the direct load-bearing component of the fill light, the dual connection method of "magnetic pre-fixing + bolt locking" simplifies the installation process (initial positioning can be achieved without lifting) and ensures the stability of the connection.

[0026] Magnetic ring 7: The magnetic ring 7 (made of high-temperature resistant neodymium iron boron) is inserted into the slot of the supplementary light mounting base 3 by interference fit. The spacer ring 8 (made of non-magnetic brass) is fitted on the outside of the magnetic ring 7, and the gap between the magnetic ring 7 and the inner wall of the slot is filled with silicone rubber sealant. The magnetic ring 7 realizes the quick pre-fixation of the supplementary light, solving the pain point of "one person holding up and one person locking" in traditional installation. The spacer ring 8 prevents the magnetic field from leaking out and interfering with other equipment, while the sealant isolates the water vapor and dust in the greenhouse, preventing the magnetic ring 7 from rusting or losing its magnetic properties.

[0027] The drive motor 5 has a built-in electromagnetic lock 6.

[0028] Electromagnetic locking device 6: The drive motor 5 (selected as a DC geared motor) is rigidly fixed to the side wall of the support rod 4 via a flange. The output shaft is connected to the end of the rotating shaft via a flat key to ensure efficient torque transmission. The electromagnetic locking device 6 is integrated inside the motor, and its locking tongue corresponds to the slot of the motor output shaft. When locked, the locking tongue extends into the slot to restrict the rotation of the shaft. The drive motor 5 provides power for angle adjustment, controls the rotation direction of the rotating shaft through forward and reverse rotation, and controls the rotation angle through pulse signals. The electromagnetic locking device 6 locks immediately after the angle adjustment is completed to prevent angle deviation caused by greenhouse vibration and airflow impact, ensuring long-term stability of the supplementary lighting angle.

[0029] The surfaces of the greenhouse fixing base 1, the folding bracket body 2, and the supplementary lighting fixing base 3 are all covered with an anti-corrosion coating, and the anti-corrosion coating is a galvanized layer.

[0030] Anti-corrosion coating (galvanized layer): The metal surfaces of the greenhouse fixing base, the main body of the folding bracket 2, and the supplementary light fixing base 3 are hot-dip galvanized to form a uniform anti-corrosion film layer, covering all exposed metal parts. By physically isolating the metal from the corrosive environment, the service life of the fixing frame is extended, the frequency of maintenance is reduced, and the long-term cost for growers is reduced.

[0031] The magnetic ring 7 is made of high-temperature resistant neodymium iron boron material.

[0032] The greenhouse mounting base 1 has an internal cavity, and a microcontroller 10 and a wireless connection unit 9 are installed inside the cavity. The microcontroller 10 and the wireless connection unit 9 are electrically connected, and the wireless connection unit 9 is a WiFi 6 module.

[0033] Microcontroller 10 and Wireless Connection Unit 9 (WiFi 6 Module): Microcontroller 10 and WiFi 6 module are connected via DuPont wires and installed together in the cavity of greenhouse mounting base 1, with heat insulation cotton pasted on the inner wall of the cavity. Their power supply lines are connected to the greenhouse power supply via wires, which pass through the hollow support rod 4 of the folding bracket body 2. Serving as the "brain" of the entire system, microcontroller 10 receives external commands transmitted by the WiFi 6 module, converts them into motor control signals, and realizes remote automated adjustment of the supplementary lighting angle. The WiFi 6 module supports multi-device connection, adapting to the intelligent management needs of large-scale greenhouses.

[0034] The working principle of the adjustable light angle supplemental lighting fixture for greenhouses in this embodiment is as follows: After the greenhouse mounting base 1 is fixed to the greenhouse frame, the two support rods 4 of the folding bracket body 2 are hinged in sequence. The supplemental lighting is pre-attached to the supplemental lighting fixture 3 through the magnetic ring 7 and then locked with bolts. The electrical components are connected by cables to complete the system assembly. The user sends an angle command through an external device, and the WiFi 6 module transmits the command to the microcontroller 10. The microcontroller 10 drives the motor 5 to rotate, which drives the folding bracket body 2 and the supplemental lighting fixture 3 to adjust the angle through the rotating shaft. After the angle is reached, the microcontroller 10 triggers the electromagnetic lock 6 to lock, completing the adjustment.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
