Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a photoperiod simulation aquaculture lamp. Background Technology

[0002] In aquaculture, light is a crucial environmental factor that directly impacts the growth rhythms, reproductive cycles, and physiological health of aquatic organisms. For example, fish need light to regulate melatonin secretion to maintain metabolic balance; shrimp and crab larvae are sensitive to light intensity and spectral distribution during development; and shellfish rely on specific photoperiods to induce gonadal maturation. However, traditional aquaculture lighting equipment suffers from several significant drawbacks: First, insufficient adjustment capabilities in light position and angle. Existing aquaculture lights are mostly fixed installations or only have simple up-and-down and left-and-right oscillation functions, making it difficult to simulate the dynamic trajectory of natural light over time (e.g., sunrise and sunset) and seasons (e.g., changes in solar altitude angle), thus failing to meet the needs of aquatic organisms for refined photoperiod simulation. Second, limited spectral adaptability. Traditional lamps often use a single white light or a fixed proportion of blue-green light, making it difficult to provide specific spectra for different aquaculture species (e.g., fish, shrimp, crab, shellfish) or different growth stages (e.g., seedling stage, growth stage), thus limiting the role of light quality control in improving aquaculture efficiency. Third, poor adjustment precision and stability. Some adjustable aquaculture lights use gear and rack or belt drive mechanisms, which are susceptible to jamming or displacement deviations due to load effects. Over long-term use, positioning accuracy decreases, making it impossible to guarantee consistent lighting parameters. Fourth, there are issues with heat dissipation and reliability. High-power LED light sources generate concentrated heat during operation. If the heat dissipation design is inadequate, it can lead to accelerated light decay of the LED chips, shortened lifespan, and increased maintenance costs.

[0003] Therefore, there is an urgent need to develop an aquaculture lamp with multi-degree-of-freedom adjustment, multi-spectral adaptation, high-precision stable operation, and efficient heat dissipation to meet the needs of modern intelligent and refined aquaculture. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a photoperiod simulation aquaculture lamp.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a photoperiod simulation aquaculture lamp, comprising: a rotating base with a horizontal rotation drive mechanism fixedly connected to its top; an L-shaped rotating bracket, the bottom of its vertical section being coaxially fixedly connected to the output end of the horizontal rotation drive mechanism, and a horizontal guide groove being formed along the length direction on the inner side of the horizontal section; a horizontal telescopic arm, slidably connected within the horizontal guide groove, and driven to extend and retract horizontally by a telescopic drive assembly; a fixed bracket, the top of which is fixedly connected to the end of the horizontal telescopic arm, and a downwardly extending mounting frame fixedly connected to its bottom; an angle adjustment assembly, disposed below the mounting frame, for driving the light source assembly to swing around a horizontal axis; and a light source assembly, rotatably connected to the fixed bracket via the angle adjustment assembly, with its light-emitting surface facing the aquaculture area below.

[0006] As a preferred embodiment of this utility model, the telescopic drive assembly includes: a horizontal telescopic arm, which is a rectangular tubular structure, with a sliding boss in the middle of its outer wall that slides in cooperation with the horizontal guide groove; a telescopic drive motor, fixed to the end of the horizontal section of the L-shaped rotating bracket; and a screw-nut pair, including a translation drive screw rotatably disposed within the horizontal section and a drive nut fixedly connected to the sliding boss. The output end of the telescopic drive motor is connected to the translation drive screw, and the horizontal telescopic arm is driven to extend and retract along the horizontal guide groove by driving the drive nut.

[0007] As a preferred embodiment of this utility model, the angle adjustment assembly includes: a guide shaft consisting of two parallel linear guide rails fixed to the bottom of the mounting bracket by bolts; an angle adjustment screw parallel to the guide shaft, one end of which is fixedly connected to the output end of the angle adjustment motor, and the other end is rotatably supported on the bottom of the mounting bracket via an angle adjustment bearing seat; a slider sleeved on the guide shaft and the angle adjustment screw, threadedly engaged with the angle adjustment screw; and a swing rod, the upper end of which is connected to the bottom of the slider via a ball joint, and the lower end of which is hinged to the hinge seat on the back of the light source assembly via a pin. The angle adjustment motor drives the angle adjustment screw to rotate, thereby causing the slider to reciprocate along the guide shaft, and then, through the swing rod, pushes the light source assembly to rotate around its connecting shaft with the fixed bracket.

[0008] As a preferred technical solution of this utility model, the light source assembly includes: a lamp housing, which is rectangular in shape and made of aluminum alloy, with two parallel triangular fixing seats fixedly connected to the center of the back side, and a through-hole rotating shaft hole on the side of the fixing seat; a lamp assembly rotating shaft, with both ends inserted into the rotating shaft holes of the two fixing seats respectively, and rotatably connected to the fixed bearing seat at the bottom of the fixed bracket through a deep groove ball bearing; a hinge seat, which is fixed to the bottom of the back side of the lamp housing by bolts and hinged to the lower end of the swing rod of the angle adjustment assembly; and an LED light-emitting screen, which is embedded in the front of the lamp housing and is composed of several independently controlled LED beads arranged in a matrix, wherein the LED beads are divided into three spectral types: warm white light, cool white light, and blue light.

[0009] As a preferred technical solution of this utility model, the light-emitting surface of the LED light-emitting screen is covered with an optical diffusion plate. The optical diffusion plate is made of PC and has a microprism structure imprinted on its surface. The apex angle of the microprism structure is 90°~120°.

[0010] As a preferred technical solution of this utility model, heat dissipation fins are uniformly welded along the length direction inside the lamp housing. The heat dissipation fins are made of aluminum alloy and are in close contact with the back of the LED light-emitting screen through thermally conductive silicone grease.

[0011] As a preferred embodiment of this utility model, the horizontal rotation drive mechanism is a worm gear reducer motor, the output end of which is connected to the bottom spline of the vertical section of the L-shaped rotating bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the three-level coordination of the horizontal rotation drive mechanism (worm gear reducer motor), the horizontal telescopic arm (screw-nut pair drive), and the angle adjustment component (screw-slider-swing rod linkage), the lamp can achieve three-dimensional dynamic adjustment of azimuth (left and right turning), horizontal position (forward and backward extension), and height angle (pitch swing), accurately reproduce the trajectory of natural light changes with time and season (such as the azimuth and angle of sunrise and sunset), and meet the physiological needs of aquatic organisms for photoperiod. 2. The light source component adopts an LED lamp bead matrix arrangement with three spectra: warm white light, cool white light and blue light. The proportion of each spectrum can be adjusted independently. For different species such as fish, shrimp, crab and shellfish or different stages such as seedling and growth period, the best light quality parameters can be customized and matched (such as blue light to promote pigment synthesis and specific wavelength light to regulate reproduction), which significantly improves breeding efficiency and quality. 3. Aluminum alloy heat dissipation fins are uniformly welded along the length of the lamp housing and are in close contact with the back of the LED light-emitting screen through thermal grease. This quickly dissipates the heat generated by the LED during operation, reduces the junction temperature of the LED beads, slows down light decay, significantly extends the life of the lamp, and reduces maintenance costs. 4. The LED light-emitting screen is covered with a PC material optical diffusion plate with a 90°~120° microprism structure imprinted on the surface, which can evenly disperse light and adjust the light emission angle, avoid local glare or dark areas, and improve the uniformity of lighting in the aquaculture area; at the same time, it reduces light pollution and meets the optical requirements of the aquaculture environment.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] In the attached diagram, all identical reference numerals refer to the same components.

[0016] Example 1: Basic Photoperiodic Simulation Aquaculture Lamp like Figure 1-5As shown, this embodiment is a basic configuration suitable for factory-scale fish fry ponds, with the following structure: The rotating base 1 is a cast iron disc, fixed to the ceiling above the pond by expansion bolts. A horizontal rotating drive mechanism 11 is fixed to the center of the top—here, a worm gear reducer motor is selected, with the output shaft facing upwards and connected to the bottom of the vertical section 21 of the L-shaped rotating bracket 2 via a spline. The vertical section 21 of the L-shaped rotating bracket 2 is a square steel tube, and the horizontal section 22 is formed by bending a steel plate, with a rectangular horizontal guide groove 221 opened on the inner side along the length direction.

[0017] The horizontal telescopic arm 3 is an aluminum alloy rectangular tube, with a sliding boss 31 welded to the middle of its outer wall, which slides into the horizontal guide groove 221. A telescopic drive motor 32 is fixed to the end of the horizontal section 22 of the L-shaped rotating bracket 2. An internal translation drive screw 33 is rotatably mounted via bearings, and the screw 33 is threadedly engaged with a drive nut 34 fixed to the sliding boss 31. When the telescopic drive motor 32 is energized, the screw 33 rotates, driving the nut 34 to move axially along the screw, thus extending and retracting the horizontal telescopic arm 3 along the horizontal guide groove 221, adjusting the front and rear positions of the lamp.

[0018] The fixed bracket 4 is an inverted L-shaped frame welded from steel plates. The top is bolted to the end of the horizontal telescopic arm 3, and the bottom extends downward to be fixed to the mounting bracket 41. The mounting bracket 41 consists of two parallel angle steels with a spacing that matches the angle adjustment component 5.

[0019] Please see Figure 2 In the angle adjustment assembly 5, two guide shafts 51 are linear guides, fixed parallel to the bottom of the mounting bracket 41 by bolts; the angle adjustment screw 52 is parallel to the middle of the two guide shafts 51, one end is fixed to the output shaft of the angle adjustment motor 53, and the other end is rotatably supported on the bottom of the mounting bracket 41 through the angle adjustment bearing seat 55; the slider 54 is sleeved on the guide shaft 51 and the angle adjustment screw 52, ​​and is threadedly engaged with the angle adjustment screw 52. The bottom of the slider 54 is connected to the upper end of the swing rod 56 through a ball joint, and the lower end of the swing rod 56 is hinged to the hinge seat 64 on the back of the light source assembly 6 through a pin. When the angle adjustment motor 53 drives the angle adjustment screw 52 to rotate, the slider 54 slides along the guide shaft 51, and pushes the light source assembly 6 to swing around the lamp group rotation axis 62 through the swing rod 56, thereby adjusting the illumination pitch angle.

[0020] Please see Figure 5In the light source assembly 6, the lamp housing 60 is an aluminum alloy rectangular plate with two parallel triangular mounting bases 61 welded to the center of the back. Through-holes are formed on the sides of the mounting bases 61. The lamp assembly's rotating shaft 62 is inserted into the mounting bases 61's rotating holes at both ends and rotatably connected to the fixed bearing seat 63 at the bottom of the fixed bracket 4 via deep groove ball bearings. An LED light-emitting screen 65 is embedded in the front of the lamp housing 60, composed of warm white, cool white, and blue LED beads 651 arranged in a matrix, allowing independent control of the brightness of each spectrum. The light-emitting surface of the LED light-emitting screen 65 is covered with a PC material optical diffuser plate 652, with a microprism structure 653 imprinted on the surface for homogenizing light and adjusting the light emission angle. Aluminum alloy heat dissipation fins 601 are welded along the length of the interior of the lamp housing 60, making close contact with the back of the LED light-emitting screen 65 via thermally conductive silicone grease 602, transferring heat to the outside air.

[0021] This embodiment uses three-dimensional adjustment of horizontal rotation, extension and retraction, and angle swing, combined with multispectral LEDs, to simulate the light trajectory of sunrise and sunset, and is suitable for photoperiod control during the fish fry cultivation stage.

[0022] Example 2: Enhanced heat dissipation type aquaculture lamp This embodiment optimizes the heat dissipation design based on Embodiment 1, and is suitable for high-power, long-term operation scenarios in shrimp and crab breeding ponds.

[0023] The structure of the light source assembly 6 is the same as that in Embodiment 1, except that: a miniature cooling fan is added to the back of the lamp housing 60, and the fan power cable passes through the lamp housing 60 and connects to an external power source; the density of the heat dissipation fins 601 is increased by 50%, the height is increased by 20%, and a guide shroud is added between the fins to guide airflow along the fin direction, enhancing convection heat dissipation. In addition, a copper thermal pad is added between the LED light-emitting screen 65 and the thermal grease 602 to reduce contact thermal resistance and further improve the heat conduction efficiency from the LED beads 651 to the heat dissipation fins 601.

[0024] This embodiment, through the combined design of active and passive heat dissipation, can control the LED junction temperature below 70°C, extending the lifespan of the LED beads to over 50,000 hours, making it suitable for high-intensity aquaculture scenarios that operate continuously for 24 hours.

[0025] Example 3: Intelligent Multispectral Controlled Aquaculture Light This embodiment focuses on precise spectral control and is suitable for scenarios with strict requirements for light quality, such as the induction of gonadal maturation in shellfish.

[0026] In the light source assembly 6, the three types of LED beads 651 of the LED light-emitting screen 65 are connected to independent drive modules. The drive modules communicate with an external controller and can adjust the brightness ratio of each spectrum in real time (e.g., 30% warm white light, 50% cool white light, and 20% blue light). The apex angle of the microprism structure 653 of the optical diffuser plate 652 is adjusted to 105°. With the controller setting, the light emission angle is concentrated between 120° and 150°, accurately covering the shellfish farming area. The angle adjustment motor 53 and the telescopic drive motor 32 of the angle adjustment assembly 5 are replaced with servo motors. With encoder feedback, the positioning accuracy is improved to ±0.1°, which can simulate more refined natural light trajectories (e.g., the light angle changes corresponding to the tidal cycle).

[0027] This embodiment, through multispectral independent control and high-precision drive, can achieve precise regulation of light quality at specific growth stages of shellfish, increasing the gonadal maturation rate by 15%~20%, and is suitable for high-end shellfish farming.

[0028] All the above embodiments are based on the core structure design of this utility model, and through the combination of different functional modules, they meet the photoperiod simulation needs of diverse aquaculture scenarios.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
