Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to a plant lighting device which mainly performs light compensation on plants. Background Art

[0002] Plants cannot grow without sunlight, but sunlight cannot shine on plants 24 hours a day. In order to provide light compensation for plants, people have already designed plant lighting devices, such as the Chinese patent authorization announcement number CN216532740U "A LED ground-inserted circular plant lighting lamp", which includes a ground-inserted rod assembly and at least one lighting assembly. The lighting assembly is in a hollow ring shape and the bottom is transparent. The lighting assembly is sleeved on the ground-inserted rod assembly, and the lighting assembly slides up and down along the ground-inserted rod assembly, and / or the lighting assembly rotates around the axis of the ground-inserted rod assembly to meet the lighting needs of plants in different periods and directions. However, the lighting lamp is installed on the ground-inserted rod assembly through the mounting hole. Although there is an anti-slip gasket to prevent it from sliding down, after a long time of use, under the weight of the lighting lamp, it is inevitable that the lighting assembly will slide down on the ground-inserted rod assembly, and in order to meet the lighting needs of commercial greenhouse plants, it is bound to require the lighting lamp to have a large enough volume, so the increase in the weight of the lighting fixture will make it more prone to sliding. Furthermore, during assembly, one hand is required to hold the lighting assembly and the other hand to hold one of the support rods in the ground rod assembly. When the lighting assembly is large and heavy, the difficulty of assembly will increase and even require the cooperation of multiple people to complete. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a plant lighting device which is easy to assemble and has a stable assembly structure in view of the current status of the prior art.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a plant lighting device, including an upright support column and at least one group of lighting components installed on the support column, characterized in that: a plurality of positioning pins matching the number of lighting components are arranged at intervals along the height direction on the support column, and both ends of the positioning pins are exposed at the corresponding side surfaces of the support column, the lighting component includes a lighting lamp, a cross bar for installing the lighting lamp and distributed perpendicularly to the support column, and a support seat fixed on one end of the cross bar, the support seat is provided with a recess for the corresponding support column to be inserted laterally, the insertion opening of the recess is facing away from the cross bar, and L-shaped positioning grooves for the corresponding ends of the positioning pin to slide into are correspondingly opened on the two side walls of the recess, when the two ends of the positioning pin respectively enter the top wall of the vertical part from the opening of the horizontal part of the corresponding L-shaped positioning groove, the support column is tightly attached to the inner wall of the recess.

[0005] In order to ensure that the assembled lighting assembly is in a horizontal state, a further improvement is that the support seat is provided with a screw hole located below the cross bar, and an adjustment bolt with a head abutting against the outer wall of the support column is threadedly connected in the screw hole.

[0006] In order to install more lighting lamps, it is better that horizontally arranged mounting rods are fixed to both ends of the cross bar, and both ends of the lighting lamps are connected to the corresponding mounting rods respectively.

[0007] In the above scheme, in order to facilitate the installation of the lighting lamps, each of the mounting rods is provided with a mounting seat matching the number of the lighting lamps, each mounting seat has two oppositely arranged clamping feet extending downward, and a clamping portion is provided on the lamp housing of the lighting lamp. The lighting lamp is installed on the cross bar through the cooperation of the clamping portion on the lamp housing and the two clamping feet on the corresponding mounting seat on the corresponding mounting rod.

[0008] In order to prevent the lighting lamp from shaking after installation, a further improvement is that each of the mounting seats is also provided with an elastic foot that abuts against the top surface of the lamp housing.

[0009] A further improvement is that, corresponding to each mounting seat, the bottom of the mounting rod is also hinged with a swing seat, each mounting seat is fixed on the bottom surface of the corresponding swing seat, and a plurality of driving mechanisms corresponding to the number of lighting lamps are also arranged on the crossbar, and the driving mechanism can drive the two swing seats corresponding to each lighting lamp to swing synchronously around an axis parallel to the crossbar, so that each lighting lamp can swing as needed, which can better meet the lighting needs of the plants.

[0010] Preferably, the driving mechanism includes a motor and a rotating shaft connected to the output end of the motor and parallel to the crossbar, eccentric wheels are respectively installed at both ends of the rotating shaft, and an eccentric shaft is installed on each eccentric wheel, and long holes extending in the up-down direction and for the eccentric shaft on the corresponding eccentric wheel to be inserted are respectively opened on the two side walls of the swing seat. The long holes on both sides can avoid twisting during swinging.

[0011] In order to make the overall structure more compact and more stable, the support column is uprightly fixed on the base plate, and the base plate also supports a support plate for placing plants under the corresponding lighting assembly.

[0012] Preferably, the upper and lower adjacent support plates are connected by a plurality of columns to facilitate assembly.

[0013] More practically, a wire clamping seat capable of restraining the wires is fixed on the outer side surface of the support seat to facilitate wiring and assembly.

[0014] Compared with the prior art, since the support column of the utility model is provided with exposed positioning pins at both ends, and a support seat is additionally provided on the cross bar on which the lighting lamp is installed, when in use, the support seat can be surrounded on the support column by utilizing the recess on the support seat, and with the help of the cooperation between the L-shaped positioning grooves on the two side walls of the support seat and the positioning pins, the lighting component can be reliably installed on the support column under the action of its own weight, and during the installation process, assembly can be achieved by simply holding the cross bar, so it is convenient to assemble, and the lighting component will not slide down after assembly, so the assembly structure is stable and easy to implement.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The first embodiment, as Figures 1 to 6As shown, it is a preferred embodiment of the utility model. In this embodiment, the plant lighting device includes an upright support column 10 and a plurality of groups of lighting components 20 installed on the support column and spaced apart from each other, wherein the support column 10 is directly fixed on a base plate 30 and adjacent to one side of the base plate 30. The base plate 30 can be fixed on the foundation as required, or rollers can be installed, so that it can be easily moved to a suitable occasion as required. A plurality of positioning pins 40 matching the number of lighting components 20 are arranged at intervals along the height direction on the support column 10, and both ends of the positioning pin 40 are exposed on the corresponding side of the support column 10. In the figure, the positioning pin 40 adopts a long bolt, and the two ends are limited by the head of the long bolt and the nut threaded on the long bolt. Of course, according to needs, a pin shaft can also be used, and the end is limited by an open radial pin. The lighting assembly 20 includes a lighting lamp 1, a cross bar 2 for mounting the lighting lamp 1 and which is vertically distributed with a support column 10, and a support seat 3 fixed on one end of the cross bar 2. The support seat 3 is provided with a recess 31 for the corresponding support column 10 to be inserted laterally. The insertion opening of the recess 31 faces away from the cross bar 2, and L-shaped positioning grooves 32 for the corresponding ends of the positioning pins to slide into are correspondingly opened on the two side walls of the recess 31. The support seat 3 in the figure is designed as a horizontally placed U-shaped structure, and the L-shaped positioning grooves 32 are located on the two side walls of the U-shaped structure. The opening of the L-shaped positioning groove is located in its horizontal part, in the same direction as the insertion opening of the support seat 3. When the two ends of the positioning pin 40 respectively enter the top wall of the vertical part from the opening of the horizontal part of the corresponding L-shaped positioning groove 32, the support column 10 is tightly attached to the inner wall of the recess 31, see Figure 1 and Figure 2 .

[0025] In order to meet the needs of high-power lighting, the illuminating lamp 1 on the above-mentioned illuminating assembly 20 can be designed to be multiple. In the figure, two illuminating lamps 1 are installed. In order to stably place the two illuminating lamps on the same crossbar 2, preferably, horizontally arranged mounting rods 4 are fixed to both ends of the crossbar 2, and the two ends of the illuminating lamp 1 are respectively connected to the corresponding mounting rods 4. In addition, in order to achieve a quick connection between the illuminating lamp 1 and the mounting rod 4, a mounting seat 5 matching the number of the illuminating lamps 1 is provided on each mounting rod 4, and each mounting seat 5 has two clamping feet 51 extending downward and arranged oppositely. A clamping part 12 is provided on the lamp housing 11 of the illuminating lamp 1. The illuminating lamp 1 is installed on the crossbar 2 through the cooperation of the clamping part 12 on the lamp housing and the two clamping feet 51 on the mounting seat 5 on the corresponding mounting rod, that is, the bayonet formed by the two clamping feet 51 and the clamping part 12 on the lamp housing are elastically clamped to achieve a quick assembly of the two. At the same time, in order to prevent the lamp 1 from shaking up and down after being clamped, each mounting seat 5 is also provided with an elastic foot 52 that abuts against the top surface of the lamp housing, see Figure 6 .

[0026] Since the cross bar 2 and the lighting lamp 1 are both in the shape of long strips, due to their own weight, the suspended ends of the cross bar 2 and the lighting lamp 1 may sink after assembly. In order to prevent this phenomenon from occurring, a screw hole 33 is opened on the support seat 3 below the cross bar 2 (in the figure, the screw hole is formed by welding a screw sleeve to the through hole of the support seat to increase the connection strength with the adjusting bolt described below), and an adjusting bolt 6 with a head abutting against the outer wall of the support column 10 is threadedly connected in the screw hole 33. The bolt 6 is tightened so that its end abuts against the outer wall of the support column 10, and the position of the support seat 3 relative to the support column 10 is adjusted to ensure that the cross bar 2 and the lighting lamp 1 are in a horizontal state.

[0027] Since each lighting assembly 20 needs to be powered, power lines and other wires will be routed along the support column 10. In order to prevent the wires from being messy, a wire clamping seat 50 is fixed on the outer surface of the support seat 3 to constrain the wires when they are routed up and down.

[0028] When in use, the lighting device is moved so that each lighting assembly is located above the plants to be illuminated. In this embodiment, in order to make the overall structure more compact, a support plate 60 for placing plants located below the corresponding lighting assembly 20 is also supported on the above-mentioned bottom plate 30, and the upper and lower adjacent support plates 60 are connected by four columns 70, and the lowest support plate stands on the bottom plate by four legs 80, so the plants to be illuminated can be directly placed on the corresponding support plate.

[0029] The second embodiment, as Figure 7 and Figure 8 As shown, it is different from the above-mentioned first embodiment in that: each lighting lamp 1 can be swung as needed to better meet the lighting needs of plant growth. In the figure, corresponding to each mounting seat 5, the bottom of the mounting rod is also hinged with a swing seat 7, and each mounting seat 5 is fixed on the bottom surface of the corresponding swing seat 7. At the same time, a plurality of driving mechanisms 8 corresponding to the number of lighting lamps 1 are also arranged on the cross bar 2. The driving mechanism 8 can drive the two swing seats 7 corresponding to each lighting lamp 1 to swing synchronously around an axis parallel to the cross bar 2. In the figure, the driving mechanism 8 includes a motor 81 and a rotating shaft 82 connected to the output end of the motor 81 and parallel to the cross bar 2. In order to install the motor 81 and support the rotating shaft 82, three auxiliary rods 9 parallel to the mounting rod 4 are fixed at intervals on both sides of the cross bar 2. The motor 81 is fixed on the end of the auxiliary rod 9 in the middle position, and the ends of the other auxiliary phases are installed with bearings 83. The rotating shaft 82 is supported in the bearings 83. Eccentric wheels 84 are respectively installed at both ends of the rotating shaft 82, and an eccentric shaft 85 is installed on each eccentric wheel 84. Long holes 71 extending in the up and down directions are respectively opened on the two side walls of the swing seat 7, and the eccentric shafts 85 are inserted into the corresponding long holes 71.

[0030] When it is necessary to swing the lighting lamp 1, start the corresponding motor 81 to rotate each shaft 82, and drive the eccentric wheel 84 at the end of the shaft to rotate, and then drive the swing seat 7 to swing around the hinge axis of the swing seat through the movement of the eccentric shaft 85 in the long hole 71, and finally realize the synchronous swing of the lighting lamps 1 under the two swing seats. Since the eccentric shaft 85 is inserted into the long holes 71 on the two side walls of the swing seat 7, no torsion will occur when the swing seat 7 swings, making the swing of the lighting lamp 1 smoother and more stable.
