Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
Embodiment one:
In Fig. 1, embodiment shown in Fig. 2, which includes spherical buoyancy compartment 1;The buoyancy compartment 1
It is covered with photovoltaic panel 2 on half of spherical surface, is in addition equipped with LED lamp holder 3 in half spherical surface, in the present embodiment, which is LED
Panel is fixed in buoyancy compartment 1 areola, and the buoyancy compartment surface and the part of the LED panel face are transparent
Shape;The line of centres of the center of the LED lamp holder 3 and the photovoltaic panel 2 passes through the centre of sphere of the buoyancy compartment 1;The buoyancy compartment 1
Center be additionally provided with the battery 4 for being matched with the photovoltaic panel 2, the centre of sphere weight of the center of gravity of the battery 4 and the buoyancy compartment 1
It closes;The center of the buoyancy compartment 1 is additionally provided with gravity center adjusting mechanism;The gravity center adjusting mechanism be matched with daytime night differentiate mould
Block;The gravity center adjusting mechanism makes the center of gravity of entire water surface photovoltaic LED lamp fall within the buoyancy compartment centre of sphere and the photovoltaic panel at night
On the line at center, as shown in the P point in Fig. 2;During the day, the center of gravity of entire water surface photovoltaic LED lamp is made to fall within buoyancy compartment ball
On the heart and the line at the LED lamp holder center, shown in Q point as shown in figure 1.
In the present embodiment one, the gravity center adjusting mechanism includes servo motor 51 and the clump weight being driven by it 52;It is described
Servo motor 51 is at night, as shown in Fig. 2, clump weight 52 is made to turn to the line of the buoyancy compartment centre of sphere Yu the photovoltaic panel center
On;And during the day, as shown in Figure 1, turning to clump weight 52 on the buoyancy compartment centre of sphere and the line at the LED lamp holder center.
The Bai Tian night resolution module is electronic clock (can be directly integrated in the servo motor 51, not shown), is existed when the time
When 06:00-18:00, it is judged as daytime, and when the time is in 18:00-06:00, it is judged as night.Thus it can control on schedule
The working condition of the water surface photovoltaic LED lamp.
During the day, the gravity center adjusting mechanism falls the center of gravity of entire water surface photovoltaic LED lamp to above-mentioned water surface photovoltaic LED lamp
In on the line at the buoyancy compartment centre of sphere Yu the LED lamp holder center, thus make LED lamp holder 3 downward, and photovoltaic panel 2 is upward, i.e., as schemed
State shown in 1, to fully absorb solar energy;And when night arrives, the gravity center adjusting mechanism makes entire water surface photovoltaic LED
The center of gravity of lamp is fallen on the buoyancy compartment centre of sphere and the line at the photovoltaic panel center, so that buoyancy compartment be made to overturn to 3 court of LED lamp holder
On, i.e., state as shown in Figure 2, to make water surface Landscape Lighting;Since LED lamp holder 3 and photovoltaic panel 2 are not interfere with each other, therefore the water surface
Photovoltaic LED lamp overall volume is smaller, can flexibly arrange in large quantities in the water surface.
Embodiment two:
In embodiment two shown in Fig. 3, with embodiment one the difference is that: the gravity center adjusting mechanism includes edge
The slideway 61 that the line at 2 center of photovoltaic panel and 3 center of LED lamp holder extends;It is equipped in the slideway 61 and to be made of iron block
Weight slide block 62;The both ends of the slideway 61 are respectively equipped with a magnet exciting coil 63;When the evening draws on, the slideway 61 is in light
The magnet exciting coil for lying prostrate 2 one end of plate is connected 2-3 seconds, and the weight slide block 62 is attracted to the end that slideway is in photovoltaic panel side
Portion, and overturn buoyancy compartment 1;Come temporarily on daytime, magnet exciting coil of the slideway 61 in described 3 one end of LED lamp holder is continuous
Energization 2-3 seconds, the weight slide block 62 is attracted to the end that slideway is in LED lamp holder side, overturns buoyancy compartment 1.
For the gravity center adjusting mechanism compared to the mechanism in embodiment one including servo motor, cost is relatively low, and structure is simple, it is difficult to occur
Failure.
In addition, in example 2, the daytime night resolution module include being opened in the light transmission at the photovoltaic panel center
The photosensitive sensor 7 for being right against the loophole 20 on hole 20 and buoyancy compartment inner wall;The photosensitive sensor 7 is coupled in
The gravity center adjusting mechanism;When the collected light intensity of photosensitive sensor 7 is higher than given threshold, it is determined as daytime, lower than setting
When threshold value, it is determined as night.In this way, it can avoid in embodiment one, failure when electronic clock is walked when misalignment;In addition, can
Automatically the duration variation at the night on daytime of each Various Seasonal is adapted to, more suitably to determine the time of its LED lamp holder unlatching.This
Place, it is worth mentioning at this point that, when daytime arrives, although the photosensitive sensor 7 with photovoltaic panel 2 together towards below the water surface,
Since sunlight is easy to enter in water, and by water surface impurity scattering below, therefore still can be easily by light sensor
Device 7 captures, to judge the arrival on daytime.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
