Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ecological and environmental protection, and in particular to an underwater aquatic plant ecological auxiliary lighting device. Background Technology
[0002] Aquatic plants are an essential component of aquatic ecosystems, playing a crucial regulatory role in ecological balance. Eutrophication leads to the overgrowth of algae and other phytoplankton, resulting in algal blooms. These algae block sunlight, reducing underwater light and impacting photosynthesis in aquatic plants, thus damaging their growth environment and causing a gradual decline in aquatic plant populations. Current supplemental lighting devices suffer from poor stability; their location and coverage area easily change with water flow, failing to effectively supplement underwater ecosystems. Furthermore, existing devices often rely on simple reflective mechanisms, resulting in weak light intensity and poor illumination, and are ineffective in illuminating deeper water layers. Utility Model Content
[0003] To increase the supplementary lighting intensity of the lighting device and effectively supplement the underwater ecology, this application provides an underwater aquatic plant ecological auxiliary lighting device.
[0004] On one hand, the underwater aquatic plant ecological auxiliary lighting device proposed in this application includes a light-collecting component, a buoyancy component, a light-diffusing component, and a fixing component. The light-collecting component includes a light-collecting cover and a Fresnel lens. The top of the light-collecting cover has a light-collecting cover inlet, and the bottom has a light-collecting cover outlet. The Fresnel lens is disposed at the light-collecting cover inlet, and the focal point of the Fresnel lens is located inside the light-collecting cover outlet. The buoyancy component is disposed below the light-collecting component so that the light-collecting component can float on the water. The astigmatism assembly is disposed underwater and includes an astigmatism mask, a Fresnel concave lens, and an optical fiber bundle. The astigmatism mask has an inlet at the top and an outlet at the bottom. The Fresnel concave lens is disposed at the outlet of the astigmatism mask. The optical fiber bundle has a predetermined length, with its incident end connected to the outlet of the light-collecting mask and its exit end connected to the inlet of the astigmatism mask. A fixing assembly is disposed underwater and connected to the astigmatism assembly to fix the astigmatism assembly underwater.
[0005] According to one aspect of the embodiments of this application, both the light-collecting mask and the light-diffusing mask are conical structures, and the inner wall surfaces of both the light-collecting mask and the light-diffusing mask are provided with reflective coatings.
[0006] According to one aspect of the embodiments of this application, a traction rope is also connected between the light-collecting mask and the light-diffusing mask, and the length of the traction rope is less than the length of the optical fiber bundle.
[0007] According to one aspect of the embodiments of this application, the fixing component includes a fixing rope and a fixing post, the fixing post being disposed at the bottom of the water, and the diffuser being connected to the fixing post via the fixing rope.
[0008] According to one aspect of the embodiments of this application, the buoyancy component includes a float and a support, the support being connected to the float, and the light-collecting cover being fixed to the support.
[0009] According to one aspect of the embodiments of this application, both the light-collecting mask and the light-diffusing mask are provided with protective covers on their exteriors.
[0010] Compared with existing technologies, the underwater aquatic plant ecological auxiliary lighting device provided in this application uses a buoyancy component to float the light-collecting cover on the water surface. Light is focused by a Fresnel convex lens and enters the light-collecting cover. The light is then concentrated at the incident end of the optical fiber bundle and transmitted through the fiber bundle to the diffuser. After being diffused by a Fresnel concave lens, it illuminates the underwater plants. The optical fiber bundle has high light transmission efficiency; almost all the light entering the light-collecting cover is transmitted to the diffuser, thereby improving the supplementary lighting effect. Furthermore, the fixing component is connected to the diffuser, which can fix the diffuser and prevent the supplementary lighting area of the diffuser from changing with the water flow, thus effectively supplementing the underwater plants. Since the length of the optical fiber is adjustable, it can also supplement the lighting of underwater plants in deep water. Attached Figure Description

Detailed Implementation
[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only a part of the embodiments disclosed in this application, and not all of them. 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.
[0015] This application discloses an underwater aquatic plant ecological auxiliary lighting device, such as... Figure 1 and Figure 2 As shown, the underwater aquatic plant ecological auxiliary lighting device includes a light-collecting component 10, a buoyancy component 20, a light-diffusing component 30, and a fixing component 40.
[0016] The light-collecting assembly 10 includes a light-collecting cover 11 and a Fresnel lens 12. The top of the light-collecting cover 11 has a light-collecting cover inlet and the bottom has a light-collecting cover outlet. The diameter of the light-collecting cover inlet can be set between 20-80 cm. The Fresnel lens 12 is disposed at the light-collecting cover inlet, and the focal point of the Fresnel lens 12 is located inside the light-collecting cover outlet, thereby enabling the light to be focused at the light-collecting cover outlet.
[0017] Optionally, the light-collecting cover 11 is a conical structure, and the inner wall surface is provided with a reflective coating. The reflective coating can reflect the light back to the Fresnel lens 12, thereby achieving secondary focusing of the light and improving the utilization rate of the light.
[0018] Optionally, a protective cover is provided on the outside of the light-collecting cover 11 to protect the light-collecting component 10 from damage. The protective cover may be made of aluminum alloy or hard plastic.
[0019] A buoyancy component 20 is disposed below the light-collecting component 10 to enable the light-collecting component 10 to float on the water surface. The buoyancy component 20 includes a float 21 and a support 22, with the support 22 connected to the float 21 and the light-collecting cover 11 fixed to the support 22. Specifically, there can be 2-3 floats 21 connected together by the support 22, and the protective cover of the light-collecting component 10 is mounted on the support 22.
[0020] The diffuser assembly 30 is installed underwater. The diffuser assembly 30 includes a diffuser cover 31, a Fresnel concave lens 32, and an optical fiber bundle. The top of the diffuser cover 31 has a diffuser cover inlet 34, the diameter of which can be set between 20-80 cm. The bottom has a diffuser cover outlet. The Fresnel concave lens 32 is located at the diffuser cover outlet and can diffuse the light inside the light collector 11 to increase the illumination area. The optical fiber bundle is composed of several optical fibers and has a predetermined length. The specific length of the optical fiber bundle 33 can be set according to the water depth. The incident end of the optical fiber bundle is connected to the light collector outlet of the light collector 11, and the emitting end is connected to the diffuser cover inlet 34.
[0021] Optionally, the diffuser 31 is a conical structure, and the inner wall of the diffuser 31 is provided with a reflective coating. The reflective coating can reflect and focus the scattered light emitted by the fiber bundle 33 into a parallel beam, which can improve the supplementary lighting effect of the diffuser 31 and make the supplementary lighting more uniform.
[0022] Optionally, a protective cover is provided on the outside of the diffuser 31 to protect the diffuser assembly 30 from damage. The protective cover may be made of aluminum alloy or hard plastic.
[0023] A traction rope is also connected between the light-collecting cover 11 and the light-diffusing cover 31, and the length of the traction rope is less than the length of the optical fiber bundle. It is understood that when the wind is strong, the buoyancy component 20 causes the light-collecting cover 11 to sway under the influence of the wind, and the light-collecting cover 11 applies a certain pulling force to the optical fiber bundle 33. When the pulling force is too large, it may damage the optical fiber bundle 33. However, by setting up the traction rope, the light-collecting cover 11 acts on the traction rope, rather than the optical fiber bundle 33. Therefore, the traction rope can protect the optical fiber bundle 33 from damage due to excessive pulling force. Optionally, the traction rope can be a steel wire rope.
[0024] The fixing component 40 is disposed underwater and is connected to the light-diffusing component 30 to fix the light-diffusing component 30 underwater. The fixing component 40 is connected to the light-collecting cover 11, which can stably hold the light-collecting cover 11 and the supplementary light cover, preventing the position of the supplementary light device from changing with the water flow, thereby effectively supplementing the underwater plants with light.
[0025] Optionally, the fixing component 40 can be a weight that sinks to the bottom of the water, thereby applying a certain pulling force to the diffuser 31 and ensuring its stability. Additionally, the fixing component 40 includes a fixing rope 41 and a fixing post 42. The fixing post 42 is positioned at the bottom of the water, and the diffuser 31 is connected to the fixing post 42 via the fixing rope 41. The fixing post 42 is embedded in the bottom of the water, providing good stability; therefore, the diffuser component 30 can be stably fixed in the water by the fixing rope 41.
[0026] The implementation principle of the underwater aquatic plant ecological auxiliary lighting device in this application embodiment is as follows:
[0027] The light-collecting cover 11 is floated on the water surface by a float 21. Light is focused by the Fresnel convex lens 12 and enters the light-collecting cover 11. The light is then concentrated at the light-exit port of the light-collecting cover, i.e., the incident end of the fiber bundle 33. The light is then transmitted through the fiber bundle 33 to the diffuser 31, and finally diffused by the Fresnel concave lens 32 before illuminating the underwater plants. The fiber bundle 33 has high light transmission efficiency; almost all the light entering the light-collecting cover 11 is transmitted to the diffuser 31, thereby improving the supplemental lighting effect.
