Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse supplemental lighting equipment, and in particular to LED supplemental lighting equipment for greenhouse crops. Background Technology

[0002] The optimal growing temperature for greenhouse crops is generally above 20℃. Temperatures below 17-18℃ will cause slow growth and development, a condition known as sub-optimal temperature. Temperatures below 15℃ will lead to metabolic imbalances, a condition known as low temperature. Temperatures below 10℃ or lower will cause frost damage. With the occurrence of low or sub-optimal temperatures, the light intensity in the greenhouse decreases, necessitating artificial intervention to increase temperature and supplemental lighting. Currently, in small and medium-sized greenhouses, supplemental lighting is still achieved by winding wires with LED lights around the greenhouse roof frame. Due to the excessive height, this method makes it inconvenient to adjust the height of the LED lights, and workers cannot adjust the spacing between the bulbs in a timely manner, making it impossible to adjust the lighting according to different crops and their growth stages. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an LED supplementary lighting device for greenhouse crops. Multiple lifting components are installed inside the greenhouse frame. By controlling the raising and lowering of the light pole, the range of light illumination and temperature can be controlled. Supplementary lighting brackets are spaced apart on the light pole, with supplementary lights extending outwards on both sides. This achieves comprehensive lighting coverage while maintaining the stability of the light bracket. The light bracket is adjustable. When its position needs to be moved, the top clamping component is pried open, disengaging the contact piece from the light pole. With the assistance of the rollers on both sides, the light bracket can move freely along the light pole until a suitable position is reached. Then, the clamping component is re-engaged to fix the position. This method of adjusting the light position is simple and quick. With the lifting components, workers can quickly adjust the position without having to go to a high point in the greenhouse.

[0005] This utility model provides an LED lighting supplement device for greenhouse crops, including a greenhouse support frame with support frames spaced apart and connected to each support frame by support rods, a lifting component spaced apart on the support rods, a light pole on the lifting component, and a supplementary lighting bracket spaced apart on the light poles and slidably connected to the light poles.

[0006] The greenhouse frame is equipped with support rods on both sides, and the support rods extend downward to form lifting components. The two opposing lifting components are connected to the light pole, which controls the raising and lowering of the light pole. The light pole has a convex cross-section. The supplementary lighting bracket includes a matching groove, a balance wing, and a supplementary light. The supplementary lighting bracket is fastened to the light pole through the matching groove. The balance wing extends from both sides of the matching groove. One end of the balance wing is connected to the matching groove, and the other end of the balance wing is detachably connected to the supplementary light.

[0007] The support frame and support rod are combined to form the basic structure of the greenhouse support. A set of opposing lifting components is set between the two support frames. The lifting components control the up and down movement of the light pole and can adjust the light illumination range and irradiation temperature. Several movable supplementary lighting brackets are fastened to the light pole. Through the structural cooperation of the matching groove with the light pole, the supplementary lighting brackets can move stably without deviation. The balance wings on both sides of the supplementary lighting brackets play a balancing role and can extend the position of the supplementary light so that it is positioned above the crops on the field ridges to illuminate them.

[0008] In some embodiments, the lifting assembly includes a lifting frame, a screw, and a drive motor. The screw is provided on the inner side of each of the two corresponding lifting frames, and the light pole is screwed between the two screws. The drive motor is connected to the screw and drives the light pole to move up and down. The lifting assembly contains a screw, which, in conjunction with the drive motor, controls the up and down movement of the light pole. A set of lifting assemblies can move synchronously or asynchronously as needed, adjusting the height and tilt angle of the light pole. The specific internal structure of the lifting assembly can be found in existing technology and will not be described in detail here.

[0009] In some embodiments, roller cavities extend from both sides of the matching groove and are located on the shoulders of the U-shaped light pole. A roller is rotatably mounted within each roller cavity. Roller grooves are correspondingly formed on the shoulders of the light pole. The top of the roller is located within the roller cavity, and the bottom of the roller abuts against the roller groove. The roller cavities are used to fix the roller, and the engagement between the roller and the roller groove allows the supplementary lighting bracket to move freely along the light pole.

[0010] In some embodiments, movable slots are provided on both sides of the top of the matching slot, and a clamping assembly is rotatably mounted on the movable slot. The end of the clamping assembly abuts against the top of the light pole. The movable slots are used to accommodate the clamping assembly, which is used to fix the position of the supplementary lighting bracket. Since the supplementary lighting bracket is prone to movement during lifting and lowering, especially when subjected to large-scale shaking, it may fall off the light pole and cause damage to pedestrians or crops below. Therefore, a clamping assembly is provided to fix the position by increasing friction.

[0011] In some embodiments, the clamping assembly includes a rotating shaft, a flip-fixed plate, and an abutment. Rotating shaft holes extend from both sides of the matching groove, and the rotating shaft is rotatably mounted within these holes. The flip-fixed plate extends from the rotating shaft and is located within the movable groove. The abutment is positioned inside the flip-fixed plate and abuts against the top of the light pole. The rotating shaft holes extending from the light pole are used to fix the rotating shaft. The flip-fixed plate, through its arc-shaped front and rear ends, allows it to open and close. When the operator needs to adjust the position of the supplementary lighting bracket, the light pole is lowered, the flip-fixed plate is opened, the abutment is disengaged from its friction state, the supplementary lighting bracket is slid to a suitable position, and the flip-fixed plate is then snapped back into place to fix the position.

[0012] In some embodiments, the flip-fixing plate is further provided with an upwardly curved arc-shaped force-bearing groove. The upward curvature of the arc-shaped force-bearing groove facilitates the use of force by the operator to open the clamping assembly.

[0013] In some embodiments, the light pole has a wire channel in the middle, which runs vertically through the pole and its width is less than the gap between two movable slots. The wire channel in the middle of the light pole helps to fix the position of the wires, preventing the light pole from becoming cluttered due to wire routing, which could affect the normal movement of the supplementary lighting bracket. Correspondingly, the light pole also protects the wires.

[0014] In some embodiments, a water baffle is provided extending downwards from the side of the balancing wing. The wiring area for the supplemental light is located below the balancing wing. The power supply line is connected from the light pole and placed below the balancing wing to power the supplemental light. Since the greenhouse can also be equipped with sprinkler systems to supply water to the crops as needed, this water baffle is installed on the side to prevent water mist from affecting the power supply line during spraying, so that water droplets can fall along the edge and ensure the normal operation of the circuit.

[0015] In some embodiments, the supplementary light includes a base and a rotating bulb. A hook is provided on the side of the base, and a buckle hole is provided at the end of the balance wing. The hook engages with the buckle hole. The hook and buckle hole allow the rotating bulb to be detachably connected. To remove the rotating bulb, simply lift it upwards to disengage it from the balance wing. The rotating bulb can rotate after being connected to the base, thereby adjusting the light emission angle. The bulb is an LED bulb, and the specific structure is described in the prior art.

[0016] In some embodiments, the end of the stabilizer wing has an arc-shaped bend that matches the side of the base. Flipping the retaining plate allows the base to fit snugly against the end of the stabilizer wing, providing support for the entire fill light while maintaining an aesthetically pleasing appearance.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention incorporates multiple lifting components within the greenhouse frame. By controlling the raising and lowering of the light pole, the illumination range and temperature can be controlled. Supplementary lighting brackets are spaced apart on the light pole, with supplementary lights extending outwards on both sides. This ensures comprehensive lighting coverage while maintaining the stability of the light bracket. The light bracket is adjustable; when its position needs to be moved, the top clamping component is pried open, disengaging the contact piece from the light pole. With the assistance of rollers on both sides, the light bracket can move freely along the light pole until a suitable position is reached. The clamping component is then re-engaged to secure the position. This method of adjusting the light position is simple and quick. Combined with the lifting components, workers can achieve rapid adjustments without needing to reach high places within the greenhouse.

[0054] Reference Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the greenhouse in some embodiments of this utility model.

[0055] According to some embodiments of the present invention, the present invention provides an LED light supplementary lighting device for greenhouse crops, including a greenhouse support frame with support frames 1 spaced apart and each support frame 1 connected by support rods 2, a lifting component 3 spaced apart on the support rods 2, a light pole 4 spaced apart on the lifting component 3, and a supplementary lighting bracket 5 spaced apart on the light pole 4 and slidably connected to the light pole 4.

[0056] The greenhouse frame is equipped with support rods 2 on both sides. The support rods 2 extend downward to form lifting components 3. The two opposing lifting components 3 are connected to the light poles 4, which control the raising and lowering of the light poles 4. The light poles 4 have a convex cross-section. The supplementary lighting bracket 5 includes a matching groove 51, a balance wing 52, and a supplementary light 53. The supplementary lighting bracket 5 is fastened to the light poles 4 through the matching groove 51. The balance wing 52 extends from both sides of the matching groove 51. One end of the balance wing 52 is connected to the matching groove 51, and the other end of the balance wing 52 is detachably connected to the supplementary light 53.

[0057] The support frame 1 and the support rod 2 are combined to form the basic structure of the greenhouse support. A set of opposing lifting components 3 is set between the two support frames 1. The lifting components 3 control the up and down movement of the light pole 4 and can adjust the light illumination range and irradiation temperature. Several movable supplementary lighting brackets 5 are fastened to the light pole 4. Through the structural cooperation of the matching groove 51 with the light pole 4, the supplementary lighting brackets 5 can move stably without deviation. The balance wings 52 on both sides of the supplementary lighting brackets 5 play a balancing role and can extend the position of the supplementary light 53 so that it is located above the crops on the field ridge to irradiate them.

[0058] Reference Figure 2-3 , Figure 2 This is a schematic diagram showing the cooperation between the light pole and the supplementary lighting bracket in some embodiments of this utility model; Figure 3 This is a schematic cross-sectional view of the lamp post and the supplementary lighting bracket in some embodiments of this utility model.

[0059] According to some embodiments of this utility model, optionally, the lifting assembly 3 includes a lifting frame 31, a screw 32, and a drive motor. Each of the two corresponding lifting frames 31 has a screw 32 on its inner side, and the light rod 4 is screwed between the two screws 32. The drive motor is connected to the screw 32 and drives the light rod 4 to move up and down. The lifting assembly 3 contains a screw 32, which, in conjunction with the drive motor, controls the up and down movement of the light rod 4. A set of lifting assemblies 3 can move synchronously or asynchronously as needed, adjusting the height and tilt angle of the light rod 4. The specific internal structure of the lifting assembly 3 can be found in existing technology and will not be described in detail here.

[0060] Roller cavities 54 extend from both sides of the matching groove 51 and are located on the shoulders of the U-shaped light pole 4. A roller 55 is rotatably mounted within each roller cavity 54. Roller grooves 41 are correspondingly formed on the shoulders of the light pole 4. The top of the roller 55 is located within the roller cavity 54, and the bottom of the roller 55 abuts against the roller groove 41. The roller cavities 54 are used to fix the roller 55. Through the cooperation between the roller 55 and the roller groove 41, the supplementary lighting bracket 5 can move freely along the light pole 4.

[0061] The matching groove 51 has movable grooves 511 on both sides of its top. A clamping component 6 is rotatably mounted on the movable groove 511, and the end of the clamping component 6 abuts against the top of the light pole 4. The movable groove 511 is used to accommodate the clamping component 6, which is used to fix the position of the supplementary lighting bracket 5. Since the supplementary lighting bracket 5 is prone to movement during lifting and lowering, especially when subjected to large-scale shaking, it may fall off the light pole 4 and cause damage to pedestrians or crops below. Therefore, the clamping component 6 is provided to fix the position by increasing friction.

[0062] The clamping assembly 6 includes a rotating shaft 61, a flip-fixing plate 62, and an abutment 63. Rotating shaft holes 512 extend from both sides of the matching groove 51, and the rotating shaft 61 is rotatably mounted within these holes. The flip-fixing plate 62 extends from the rotating shaft 61 and is located within the movable groove 511. The abutment 63 is located on the inner side of the flip-fixing plate 62 and abuts against the top of the light pole 4. The rotating shaft holes 512 extending from the light pole 4 are used to fix the rotating shaft 61. The flip-fixing plate 62, through its arc-shaped front and rear ends, allows it to open and close. When the operator needs to adjust the position of the supplementary lighting bracket 5, the light pole 4 is lowered, the flip-fixing plate 62 is opened, the abutment 63 is disengaged from its friction state, the supplementary lighting bracket 5 is slid to a suitable position, and the flip-fixing plate 62 is then snapped back into place to fix the position.

[0063] The flip-fixing plate 62 is also provided with an upwardly curved arc-shaped force-receiving groove 64. The upward curve of the arc-shaped force-receiving groove 64 makes it easier for workers to use force to open the clamping assembly 6.

[0064] The light pole 4 has a wire channel 42 in the middle, which runs vertically through the pole and is narrower than the gap between the two movable slots 511. The wire channel 42 in the middle of the light pole 4 helps to fix the position of the wires, preventing the light pole 4 from becoming cluttered due to wire routing, which could affect the normal movement of the supplementary lighting bracket 5. Correspondingly, the light pole 4 also protects the wires.

[0065] Reference Figure 4 , Figure 4 This is a schematic diagram showing the connection between the stabilizer and the supplementary light in some embodiments of this utility model.

[0066] Optionally, according to some embodiments of this utility model, a water baffle 7 is provided extending downward from the side of the balance wing 52. The area below the balance wing 52 is the wiring area for the supplementary light 53. After the power supply line is connected from the light pole 4, it is placed below the balance wing 52 to power the supplementary light 53. Since the greenhouse can also be equipped with sprinkler systems and other components to supply water to the crops according to actual needs, in order to avoid the water mist during spraying affecting the power supply of the power supply line, the water baffle 7 is installed on the side so that the water droplets can fall along the edge and ensure the normal operation of the circuit.

[0067] The supplementary light 53 includes a base 531 and a rotating bulb 532. A hook 533 is provided on the side of the base 531, and a buckle hole 56 is provided at the end of the balance wing 52. The hook 533 engages with the buckle hole 56. The hook 533 and buckle hole 56 allow the rotating bulb 532 to be detachably connected. To remove the rotating bulb 532, simply lift the bulb upwards to disengage it from the balance wing 52. After being connected to the base 531, the rotating bulb 532 can rotate to adjust the light emission angle. The bulb is an LED bulb, and the specific structure is based on existing technology.

[0068] The end of the balance wing 52 is provided with an arc-shaped bend, which matches the side of the base 531. The rotating fixing piece 62 makes the base 531 fit snugly against the end of the balance wing 52, providing support for the entire fill light 53, while also being aesthetically pleasing.
