Description

Reflective hemispherical wind blade breeze power billboard

technical field

The utility model relates to a billboard, in particular to a large billboard which adopts natural wind and breeze to generate electricity.

Background technique

Today's highways, national highways, and urban highways are lined with many large billboards, which have produced great economic and social benefits. The nighttime lighting of billboards or their automatic flip mechanism requires electric energy supply, especially if the location is relatively In remote places, the electrical equipment and daily power consumption of the billboard will take up a considerable cost. Many billboards cannot be installed with lights due to the above reasons, which reduces the influence of advertising, which is not good for advertisers and enterprises. good result. Wind energy is an inexhaustible green resource. The technology of converting wind energy into electrical energy is relatively mature. The breeze power generation device, namely the breeze generator assembly generally includes the breeze generator and the wind blades arranged around it. Usually, the breeze power generation has a certain influence on the wind speed. It is required that the blades rotate when the wind speed is 1.5M/S, and it can generate electricity when the wind speed is 3-4. Have not yet seen the successful case that utilizes breeze power generation to supply outdoor large billboard lighting.

Utility model content

The utility model aims at solving the above-mentioned problems, and provides a billboard for generating electricity with reflective hemispherical blades that can generate electricity by natural wind.

The purpose of this utility model is achieved through the following measures. This reflective hemispherical fan blade breeze power billboard includes a billboard and a lighting system installed on the billboard. It is characterized in that a breeze generator assembly is arranged on the upper part of the billboard to generate electricity. A rechargeable battery and a power controller are arranged between the engine assembly and the lighting system.

The breeze generator assembly includes a breeze generator and reflective hemispherical blades connected by brackets around it.

The bottom of the reflective hemispherical fan blade is provided with a through hole, and the inside of the hemispherical fan blade is hinged with a baffle plate that can block the through hole.

An automatic power supply voltage and frequency controller is also connected between the generator assembly and the storage battery assembly.

The power controller is an electronic inverter power supply and an automatic light controller.

A lightning rod is provided on the top of the generator assembly.

The utility model has the following advantages:

1. There is little resistance when starting, and it can rotate to generate electricity even in the case of light wind.

2. Solve the problem of high cost of erecting power grids for billboards in remote locations, and make full use of wind energy to generate electricity for night lighting.

3. The lightning rod installed on the top of the large billboard can avoid the danger of lightning strike.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, this reflective hemispherical wind blade breeze power billboard is a large outdoor column billboard, the same as the existing billboard, the billboard 10 includes a column 11 and fixed on both sides of the column upper Advertisement board 12, the bottom of two advertisement boards 12 is provided with a plurality of illuminating systems that shoot to advertisement board and is illuminating lamp 13, also is provided with the climbing ladder 14 that facilitates climbing on the column 11, the difference is that, in billboard A breeze generator assembly 20 is fixed on the top of 10, and this generator assembly 20 utilizes wind energy to generate electricity for lighting at night. Referring to FIG. 2 , a rechargeable battery 40 and a power controller 50 are arranged between the generator assembly 20 and the lighting system 13 , and an automatic power supply voltage and frequency controller 60 is also connected between the generator assembly 20 and the rechargeable battery 40 . Same as the prior art, the power supply voltage and frequency automatic controller 60 is provided with a single-chip microcomputer, which is used to control the storage of wind power generation electric energy in the rechargeable battery 40, and can generate electricity at a set speed, and when the wind force exceeds the set value, The single-chip microcomputer will issue a safety separation command. At this time, the generator drive system is separated from the wind blades and operates without load. When the wind speed meets the safe power generation conditions, the single-chip microcomputer will issue a transmission connection command, and the generator can generate electricity.

In this embodiment, the power controller 50 is an electronic inverter power supply and an automatic light controller, which can automatically control the power supply of the battery to the lighting lamp. When the light is relatively weak, that is, when night comes, the dark switch sends an instruction to turn on the light, and the lighting lamp is on. When the light is relatively strong, the dark switch sends an instruction to turn off the light, and the light goes out, so that the purpose of saving electric energy can be achieved. The generator assembly 20 of this embodiment includes a generator 21 and fan blades 22 connected by brackets 26 around it. As can be seen from the figure, six reflective hemispherical fan blades 22 drive the generator assembly 20 to rotate horizontally under the push of the wind. , the wind blade 22 adopts the reflective hemispherical wind blade with high conversion efficiency that is widely used at present, and its structure is shown in Fig. The leaves are the same, and the fan blade 22 is a hemispherical shell. The difference is that the bottom of the fan blade 22, that is, the bottom of the hemispherical shell, is provided with a through hole 23, and the upper end of the fan blade inside is hinged with a baffle that can block the through hole 23 through a hinge 24. Plate 25, as shown in Figure 3B, when the wind blows in from the opening direction of the fan blade, the baffle plate 25 blocks the through hole 23 under the action of the wind, and its function is the same as that of the existing reflective hemispherical fan blade. When the wind blows in the opposite direction, that is, when it blows from the direction of the through hole 23, see Figure 3C, the baffle plate 25 swings and the through hole 23 is in an open state, which can reduce resistance. Rotate, further improve the power generation efficiency. At the same time, considering that the utility model is more often applied to outdoor large-scale billboards, because the position is relatively high, it is easy to be struck by lightning in thunderstorm days, and a lightning rod 30 can be provided on the generator assembly, see Fig. 1 , Figure 2, the purpose is to avoid lightning hazards.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the utility model belongs, on the premise of not departing from the idea of the utility model, its structure form can be flexible and changeable, and a series of products can be derived. Just making some simple deductions or substitutions should be considered as belonging to the patent protection scope of the utility model determined by the submitted claims.
