Description

Technical Field

[0001] The present application relates to the technical field of gardening design, and in particular to a tree illumination compensation device and compensation method. Background Art

[0002] Overpasses can achieve traffic diversion at different levels without interfering with each other, improve traffic efficiency, and reduce congestion on ground roads. After the construction of the overpass is completed, in order to stabilize the mud and sand under the overpass and beautify the environment, people usually choose to plant green plants under the overpass. However, since the light is blocked by the overpass, the green plants cannot carry out sufficient photosynthesis, and therefore their growth is poor. In order to ensure the normal growth of green plants and provide trees with sufficient light to meet their growth and development needs, light compensation is often required to avoid frequent replacement of green plants.

[0003] In the prior art, electric auxiliary lighting such as fill light is generally used to supplement the light for green plants. However, electric auxiliary lighting consumes more electricity and the cable laying cost is also high. Therefore, the prior art also uses natural light refraction to compensate for the light. For example, a plant lighting device under an elevated bridge disclosed in the prior art includes two light inlets on both sides of the guardrail of the elevated bridge, a concave mirror is provided at the bottom of the light inlet, and frosted glass is provided at the bottom of the bridge deck.

[0004] With respect to the above-mentioned related technologies, natural light directly shines onto the concave mirror through the light entrance. After being refracted by the concave mirror, the natural light shines onto the frosted glass provided at the bottom of the bridge deck, and then diffusely reflects onto the green plants under the viaduct through the frosted glass. However, the position of the sun gradually changes with the passage of time, while the concave mirror is fixed, resulting in a shorter total time for the concave mirror to be directly exposed to natural light, which affects the effect of auxiliary lighting for the green plants. Summary of the invention

[0005] In order to extend the natural light utilization time and improve the auxiliary lighting effect of green plants, the present application provides a tree light compensation device and compensation method.

[0006] The tree illumination compensation device and compensation method provided in this application adopt the following technical solutions:

[0007] In a first aspect, the present application provides a tree lighting compensation device.

[0008] A tree illumination compensation device, comprising:

[0009] A diffuse reflection plate, wherein the diffuse reflection plate is connected to the bottom wall of the viaduct;

[0010] Two light guide tubes, a clearance area for the viaduct to pass through is reserved between the two light guide tubes, the light guide tubes are connected to the viaduct, and two oppositely arranged reflective mirrors are arranged in the light guide tubes;

[0011] Two arc-shaped reflection plates are connected to the light outlet at the lower end of the light guide tube, and the inner arc surface of the arc-shaped reflection plate is arranged toward the diffuse reflection plate.

[0012] By adopting the above technical scheme, a tree lighting compensation device is designed, which uses a light guide tube with two oppositely arranged reflective mirrors. When natural light cannot directly hit the curved reflector, the natural light can be transmitted to the curved reflector through multiple refractions, thereby extending the utilization time of natural light. The curved reflector can reflect natural light onto the diffuse reflector, and the diffuse reflector can diffusely reflect the received natural light onto the green plant planting area below, thereby completing the lighting compensation for the green plants.

[0013] In a specific possible implementation scheme, an installation frame is provided in the light guide tube, two plaster strips are connected to the installation frame, the plaster strips are slidably connected to the reflective mirror surface, and a driving unit is connected to the light guide tube, the driving unit is connected to the installation frame, and is used to drive the plaster strips to rise and fall.

[0014] By adopting the above technical solution, the designed installation frame can be used as a supporting structure for the plastering strip. The plastering strip can be used to wipe the reflective mirror surface, reduce the influence of dust on the reflective efficiency of the reflective mirror surface, and ensure the lighting compensation effect of green plants. The driving unit can drive the installation frame to rise and fall to realize the movement of the plastering strip, thereby completing the wiping of the reflective mirror surface.

[0015] In a specific implementation scheme, the driving unit includes:

[0016] A plurality of pulling ropes, one end of each pulling rope extends from top to bottom into the light guide tube and is connected to the installation frame;

[0017] A driving member is installed on the light guide tube or the arc-shaped reflective plate, and the driving member is connected to the pulling rope, and is used to apply force to the pulling rope to make the installation frame slide upward to overcome its own gravity.

[0018] By adopting the above technical solution, the driving unit is designed, and the driving member can cooperate with the pulling rope to make the installation frame overcome its own gravity and slide upward and drive the plastering strip to slide, thereby completing the wiping of the reflective mirror surface.

[0019] In a specific embodiment, the driving member includes:

[0020] A winding rod, the winding rod is rotatably connected to the arc-shaped reflection plate;

[0021] A plurality of mounting blocks are distributed along the axial direction of the winding rod, the mounting blocks are coaxially connected to the winding rod, and a plurality of driving plates are circumferentially connected to the mounting blocks.

[0022] By adopting the above technical solution, when it rains, rainwater enters the light guide tube through the opening on the top wall of the light guide tube, then converges on the arc-shaped reflective plate, and finally converges to form a water flow that rushes towards the hydraulic wheel formed by the mounting block and multiple drive plates. The water flow drives the winding rod to rotate through the hydraulic wheel, and the winding rod winds up the pulling rope so that the mounting frame overcomes its own gravity and slides upward and drives the plastering strip to slide, thereby completing the wiping of the reflective mirror surface. After the rain stops, the gravity of the mounting frame pulls the pulling rope in the opposite direction to reset the mounting frame.

[0023] In a specific possible implementation scheme, a plurality of limit buckles are connected to the light guide tube, the pulling rope passes through the limit buckles, and the pulling rope is slidably connected to the limit buckles.

[0024] By adopting the above technical solution, the designed limit buckle can limit the position of the pulling rope, thereby preventing the pulling rope from shaking randomly and getting stuck during the pulling process.

[0025] In a specific possible implementation manner, an abutment sleeve is rotatably connected to the light guide tube, and the pulling rope is wound around the abutment sleeve.

[0026] By adopting the above technical solution, the designed abutment sleeve can convert the sliding friction between the pulling rope and the top wall of the light guide tube into rolling friction, thereby extending the service life of the pulling rope.

[0027] In a specific embodiment, the driving member includes:

[0028] A plurality of rain receiving trays with top wall openings are provided, wherein the rain receiving trays are slidably connected to the light guide tube, and the rain receiving trays are connected to an end of the pulling rope away from the installation frame.

[0029] By adopting the above technical solution, when it rains, rainwater enters the rain pan through the opening in the top wall, which increases the overall weight of the rain pan until the overall weight of the rain pan overcomes the dead weight of the mounting frame and the friction between the plaster strip and the reflective mirror surface. At this time, the rain pan applies force to the pulling rope, which causes the mounting frame to overcome its own gravity and slide upward, thereby driving the plaster strip to slide, and thus completing the wiping of the reflective mirror surface. When the rainwater in the rain pan gradually evaporates, the gravity of the mounting frame pulls the pulling rope in the opposite direction to reset the mounting frame.

[0030] In a specific feasible implementation scheme, the light guide tube is rotatably connected to two closing plates via a torsion spring, the closing plates are vertically arranged to the reflective mirror surface, and the closing plates are connected to water collecting boxes, the water collecting boxes form water storage cavities during the rotation of the closing plates, and after rainwater is accumulated in the water collecting boxes, the torsion force of the torsion spring is overcome to cause the closing plates to rotate to close the opening on the top wall of the light guide tube.

[0031] By adopting the above technical solution, the designed closing plate can change from a vertical state to a horizontal state after the weight of rainwater in the water collecting box overcomes the torsion of the torsion spring to seal the opening of the top wall of the light guide tube, thereby reducing the time that rainwater invades the light guide tube and the inside of the curved reflective plate.

[0032] In a specific possible implementation mode, a plurality of water seepage holes are provided on the water collecting box, and the water seepage holes are filled with water permeable material.

[0033] By adopting the above technical solution, it is possible to select a permeable material with a suitable water permeability according to the historical rainwater data of the installation location of the light compensation device, thereby achieving the best value between reducing the time of rainwater damage to the inside of the light guide tube and the arc reflector and the green plant light compensation effect.

[0034] In a second aspect, the present application provides a tree lighting compensation method.

[0035] A tree illumination compensation method, comprising:

[0036] Install diffuse reflective panels on the bottom wall of the viaduct above the green planting area;

[0037] Calculate the parameters of the light guide tube and the arc reflector according to the width of the green plant planting area, and prefabricate the light guide tube and the arc reflector;

[0038] The light guide tube and the arc reflector are installed according to the installation position of the diffuse reflector, and the relative angle between the arc reflector and the diffuse reflector is adjusted so that natural light is reflected by the light guide tube or directly irradiated onto the arc reflector, and then reflected by the arc reflector onto the diffuse reflector. The diffuse reflector diffuses the natural light to achieve lighting compensation for green plants.

[0039] By adopting the above technical solution, through the light guide tube with two oppositely arranged reflective mirrors, when natural light cannot directly hit the curved reflector, the natural light can be transmitted to the curved reflector through multiple refractions, thereby extending the utilization time of natural light. The curved reflector can reflect natural light onto the diffuse reflector, and the diffuse reflector can diffusely reflect the received natural light onto the green plant planting area below, thereby completing the light compensation for the green plants.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] 1. The designed tree light compensation device, through a light guide tube with two oppositely arranged reflective mirrors, can transmit natural light to the curved reflector through multiple refractions when natural light cannot directly hit the curved reflector, thereby extending the natural light utilization time. The curved reflector can reflect natural light to the diffuse reflector, and the diffuse reflector can diffusely reflect the received natural light to the green plant planting area below, thereby completing the light compensation for the green plants.

[0042] 2. The tree illumination compensation device is designed. When it rains, rainwater enters the light guide tube through the opening on the top wall of the light guide tube, and then gathers on the arc-shaped reflective plate, and finally gathers to form a water flow that rushes to the hydraulic wheel formed by the mounting block and multiple drive plates. The water flow drives the winding rod to rotate through the hydraulic wheel. The winding rod winds up the pulling rope so that the mounting frame overcomes its own gravity and slides upward and drives the plastering strip to slide, thereby completing the wiping of the reflective mirror surface. After the rain stops, the gravity of the mounting frame pulls the pulling rope in the opposite direction to reset the mounting frame.

DETAILED DESCRIPTION

[0050] The following is combined with Figure 1-5 This application is described in further detail.

[0051] The embodiments of the present application disclose a tree illumination compensation device and a compensation method.

[0052] In a first aspect, an embodiment of the present application discloses a tree lighting compensation device.

[0053] Example 1

[0054] Reference Figure 1 A tree light compensation device includes a diffuse reflection plate 1, a light guide tube 2 and an arc-shaped reflection plate 3. The diffuse reflection plate 1 is connected to the bottom wall of the viaduct 01 by bolts, and the diffuse reflection plate 1 is located directly above the green plant planting area. There are two light guide tubes 2 and two arc-shaped reflection plates 3. A space is left between the two light guide tubes 2 for the viaduct 01 to pass through. The light guide tube 2 is bolted to the viaduct 01, and two oppositely arranged reflection mirrors are arranged in the light guide tube 2. The two reflection mirrors are arranged in parallel. The arc-shaped reflection plate 3 is welded and fixed to the light outlet at the lower end of the light guide tube 2, and the inner arc surface of the arc-shaped reflection plate 3 is arranged toward the diffuse reflection plate 1. After natural light enters the light guide tube 2, it is refracted multiple times by the two reflection mirrors and irradiates the arc-shaped reflection plate 3, or the natural light directly passes through the light guide tube 2 and irradiates the arc-shaped reflection plate 3, and then reflects to the diffuse reflection plate 1, so as to complete the light compensation for the green plants.

[0055] Reference Figure 2 Since the light guide tube 2 is set outdoors and there is a lot of dust, in order to reduce the impact of dust on the reflective mirror surface, a mounting frame 4 is set in the light guide tube 2, and two plastering strips 5 are connected to the mounting frame 4. The two plastering strips 5 are slidably connected to the two reflective mirror surfaces respectively, and a driving unit 6 is set on the light guide tube 2. The driving unit 6 is connected to the mounting frame 4 and is used to drive the plastering strips 5 to rise and fall by driving the mounting frame 4 to rise and fall, thereby completing the wiping operation of the reflective mirror surface.

[0056] Reference Figure 3 Furthermore, the driving unit 6 includes a driving member 62 and a plurality of pulling ropes 61, one end of the pulling rope 61 extends from top to bottom into the light guide tube 2 and is bolted to the mounting frame 4, the driving member 62 is mounted on the light guide tube 2 or the arc-shaped reflective plate 3, and the driving member 62 is connected to the pulling rope 61, and is used to apply force to the pulling rope 61 so that the mounting frame 4 overcomes its own gravity and slides upward; in the present application, the number of pulling ropes 61 can be two, three, or four, and the number of pulling ropes 61 in the present embodiment is two.

[0057] Reference Figure 3The driving member 62 includes a winding rod 621 and a plurality of mounting blocks 622. The winding rod 621 is rotatably connected to the arc-shaped reflective plate 3, and the vertical plane where the winding rod 621 is located is arranged parallel to the reflective mirror surface. The plurality of mounting blocks 622 are distributed along the axial direction of the winding rod 621, and the mounting block 622 is coaxially connected to the winding rod 621. A plurality of driving plates 623 are evenly distributed on the circumference of the mounting block 622. The driving plate 623 is welded and fixed to the mounting block 622, and the mounting block 622 and the plurality of driving plates 623 form a hydraulic wheel. When it rains, When the rain stops, the gravity of the mounting frame 4 pulls the pulling rope 61 in the opposite direction so that the mounting frame 4 can slide upward and the plastering strip 5 can slide, thereby completing the wiping of the reflective mirror surface. After the rain stops, the gravity of the mounting frame 4 pulls the pulling rope 61 in the opposite direction so that the mounting frame 4 is reset.

[0058] Reference Figure 3 In order to limit the position of the pulling rope 61 and prevent the pulling rope 61 from shaking randomly and getting stuck during the pulling process, a plurality of limit buckles 63 are welded and fixed on the light guide tube 2, and the pulling rope 61 passes through the limit buckles 63, and the pulling rope 61 is slidably connected to the limit buckles 63; in addition, in order to convert the sliding friction between the pulling rope 61 and the top wall of the light guide tube 2 into rolling friction and extend the service life of the pulling rope 61, an abutment sleeve 64 is rotatably connected to the light guide tube 2, and the pulling rope 61 is wound around the abutment sleeve 64.

[0059] The implementation principle of a tree light compensation device in Example 1 of the present application is as follows: a diffuse reflection plate 1 is installed on the bottom wall of an elevated bridge 01 above a green plant planting area; the parameters of a light guide tube 2 and an arc-shaped reflection plate 3 are calculated according to the width of the green plant planting area, and the light guide tube 2 and the arc-shaped reflection plate 3 are prefabricated; the light guide tube 2 and the arc-shaped reflection plate 3 are installed correspondingly according to the installation position of the diffuse reflection plate 1, and the relative angle between the arc-shaped reflection plate 3 and the diffuse reflection plate 1 is adjusted, so that natural light is reflected by the light guide tube 2 or directly irradiated onto the arc-shaped reflection plate 3, and then reflected by the arc-shaped reflection plate 3 onto the diffuse reflection plate 1, and the light compensation of green plants is achieved by diffusely reflecting the natural light through the diffuse reflection plate 1.

[0060] When it rains, rainwater enters the light guide tube 2 through the opening on the top wall of the light guide tube 2, then converges on the arc-shaped reflective plate 3, and finally converges to form a water flow that rushes toward the hydraulic wheel formed by the mounting block 622 and the multiple drive plates 623. The water flow drives the winding rod 621 to rotate through the hydraulic wheel, and the winding rod 621 winds up the pulling rope 61 so that the mounting frame 4 overcomes its own gravity and slides upward and drives the plastering strip 5 to slide, thereby completing the wiping of the reflective mirror surface. After the rain stops, the gravity of the mounting frame 4 pulls the pulling rope 61 in the reverse direction to reset the mounting frame 4.

[0061] Example 2

[0062] Reference Figure 4 The difference between this embodiment and embodiment 1 is that: the driving member 62 includes a plurality of rain receiving trays 624 with top wall openings, the rain receiving trays 624 are slidably connected to the light guide tube 2, and the sliding direction of the rain receiving trays 624 is vertically set, the rain receiving trays 624 are screwed to the end of the pulling rope 61 away from the mounting frame 4, the number of the rain receiving trays 624 in this application is consistent with the number of the pulling ropes 61, and the rain receiving trays 624 are adjacent to the reflective mirror surface.

[0063] Reference Figure 4 and Figure 5 Furthermore, in order to reduce the time that rainwater invades the light guide tube 2 and the arc-shaped reflective plate 3, two closing plates 7 are rotatably connected to the light guide tube 2 through a torsion spring. The closing plates 7 are vertically arranged to the reflective mirror surface, and a clearance opening for the pulling rope 61 to pass through is opened on the light guide tube 2, so that the pulling rope 61 and the closing plates 7 are staggered. The torsion spring keeps the closing plates 7 in a vertical state. A water collecting box 8 is bolted to the closing plates 7. The water collecting box 8 is located between the two closing plates 7, and a water storage cavity is formed in the water collecting box 8 during the rotation of the closing plates 7. After a certain mass of rainwater is accumulated in the water collecting box 8, the closing plates 7 overcome the torsion of the torsion spring and rotate to a horizontal state, thereby closing the top wall opening of the light guide tube 2.

[0064] Reference Figure 5 A plurality of water seepage holes are provided on the water collection box 8, and the water seepage holes are filled with water-permeable materials. Then, the water-permeable materials with suitable water permeability can be selected according to the historical rainwater data of the installation location of the light compensation device, so as to obtain the best value between reducing the rainwater damage time to the light guide tube 2 and the arc reflector 3 and the green plant light compensation effect.

[0065] The implementation principle of a tree light compensation device in Example 2 of the present application is as follows: a diffuse reflection plate 1 is installed on the bottom wall of the viaduct 01 above the green plant planting area; the parameters of the light guide tube 2 and the arc-shaped reflection plate 3 are calculated according to the width of the green plant planting area, and the light guide tube 2 and the arc-shaped reflection plate 3 are prefabricated; the light guide tube 2 and the arc-shaped reflection plate 3 are installed correspondingly according to the installation position of the diffuse reflection plate 1, and the relative angle between the arc-shaped reflection plate 3 and the diffuse reflection plate 1 is adjusted, so that natural light is reflected from the light guide tube 2 or directly irradiated onto the arc-shaped reflection plate 3, and then reflected from the arc-shaped reflection plate 3 to the diffuse reflection plate 1, and the light compensation of the green plants is achieved by diffusely reflecting the natural light through the diffuse reflection plate 1.

[0066] When it rains, rainwater enters the rain pan 624 through the opening in the top wall, increasing the overall weight of the rain pan 624 until the overall weight of the rain pan 624 overcomes the deadweight of the mounting frame 4 and the friction between the plaster strip 5 and the reflective mirror surface. At this time, the rain pan 624 applies force to the pulling rope 61, which causes the mounting frame 4 to overcome its own gravity and slide upward, thereby driving the plaster strip 5 to slide, and thus completing the wiping of the reflective mirror surface. When the rainwater in the rain pan 624 gradually evaporates, the gravity of the mounting frame 4 pulls the pulling rope 61 in the opposite direction to reset the mounting frame 4.

[0067] When it rains, rainwater gathers in the water collecting box 8 until the weight of the rainwater in the water collecting box 8 can overcome the torsion of the torsion spring, which can make the closing plate 7 change from a vertical state to a horizontal state to seal the opening of the top wall of the light guide tube 2, thereby reducing the time that rainwater invades the light guide tube 2 and the interior of the arc-shaped reflective plate 3.

[0068] In a second aspect, an embodiment of the present application discloses a tree lighting compensation method.

[0069] A tree illumination compensation method, using the tree illumination compensation device disclosed in the first aspect of the embodiment of the present application to perform illumination compensation on green plants under the viaduct 01, comprises:

[0070] A diffuse reflection plate 1 is installed on the bottom wall of the viaduct 01 above the green plant planting area;

[0071] Calculate the parameters of the light guide tube 2 and the arc reflector 3 according to the width of the green plant planting area, and prefabricate the light guide tube 2 and the arc reflector 3;

[0072] The light guide tube 2 and the arc-shaped reflection plate 3 are installed according to the installation position of the diffuse reflection plate 1, and the relative angle between the arc-shaped reflection plate 3 and the diffuse reflection plate 1 is adjusted, so that natural light is reflected by the light guide tube 2 or directly irradiated onto the arc-shaped reflection plate 3, and then reflected by the arc-shaped reflection plate 3 onto the diffuse reflection plate 1. The diffuse reflection plate 1 diffusely reflects the natural light to achieve lighting compensation for green plants.

[0073] By applying the above-mentioned tree lighting compensation method, through the light guide tube 2 with two oppositely arranged reflective mirrors, when natural light cannot directly hit the curved reflector 3, the natural light can be transmitted to the curved reflector 3 through multiple refractions, thereby extending the utilization time of natural light. The curved reflector 3 can reflect the natural light to the diffuse reflector 1, and the diffuse reflector 1 can diffusely reflect the received natural light to the green plant planting area below, thereby completing the lighting compensation for the green plants.
