Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation utilization in buildings, in particular to a ventilation and supplementary lighting device for a factory building. Background Art

[0002] The construction of new energy photovoltaic power stations currently involves ground photovoltaic, offshore photovoltaic, lake photovoltaic, and roof photovoltaic. Currently, the available construction land is getting smaller and smaller. Some areas have vigorously carried out county-wide roof photovoltaic or industrial park roof photovoltaic. Considering that the industrial park roof photovoltaic involves a large span of factory buildings, it is necessary to set up both an exhaust system and a lighting system, resulting in the roof being unable to form a whole. In particular, some factory buildings use segmented light-transmitting tiles, and the bearing capacity cannot meet the photovoltaic layout. The roof is divided into strips, which cannot form an overall utilization effect and wastes roof resources.

[0003] In existing patent technologies, such as the Chinese patent CN211343400U disclosed on August 25, 2020, an exhaust fan is set on the roof of a building, and the rotating shaft of the exhaust fan is connected to a generator device through a belt mechanism to generate electricity, thereby realizing the conversion of the mechanical energy of the building exhaust fan into electrical energy application.

[0004] However, this type of prior art only considers using exhaust fan power generation to power aviation warning lights, and does not consider using it for lighting in factories. Furthermore, this type of prior art still cannot solve the aforementioned problem of occupying roof area resources due to the need to set up exhaust systems, lighting systems, segmented light-transmitting tiles, etc. Furthermore, in application environments such as roof photovoltaics, the utilization effect of roof resources will be low. Utility Model Content

[0005] The utility model aims to provide a factory building ventilation and supplementary lighting device, which can reduce the roof area resources occupied by the factory building roof due to the exhaust system and the lighting system, and improve the utilization rate of the roof resources.

[0006] The utility model provides a factory ventilation and supplementary lighting device, comprising: a rotary exhaust device, which is installed through the factory roof; a power generation device, which is installed in the shell of the rotary exhaust device and connected to the rotating shaft of the rotary exhaust device to generate electricity; and a lighting device, which is installed at the lower end of the shell of the rotary exhaust device, connected to the power generation device, and located on the inner side of the factory roof.

[0007] Furthermore, the rotary exhaust device is a non-powered hood.

[0008] Furthermore, the unpowered hood includes fan blades and a neck tube, the fan blades are rotatably mounted on the neck tube, and the neck tube is fixedly mounted on the roof of the factory building.

[0009] Furthermore, the power generation device includes a generator, which is fixedly installed in the neck tube of the unpowered hood and connected to the rotating shaft connected to the fan blades.

[0010] Furthermore, the power generation device also includes a rectifier connected to the generator.

[0011] Furthermore, the power generation device also includes a battery connected to the rectifier.

[0012] Furthermore, the lighting device is an LED lighting lamp.

[0013] Furthermore, the LED lighting lamp is electrically connected to the battery.

[0014] Furthermore, the LED lighting lamp is fixed at the middle part of the lower end of the neck tube of the non-powered hood.

[0015] Furthermore, the neck tube of the non-powered hood is surrounded by ventilation channels.

[0016] The technical solution of the utility model realizes power generation through exhaust by connecting a power generation device to the rotating exhaust device on the roof of the factory building; and a lighting device is installed at the lower end of the rotating exhaust device located inside the factory building, and the lighting device is used to illuminate the factory building through wind power generation. Therefore, in this device, the exhaust device and the lighting device occupy the common area of ​​the factory roof, which reduces the occupied roof area resources as a whole; the number of lighting devices is relatively increased, so that the roof structure with low bearing capacity such as transparent tiles can be relatively reduced. Therefore, in application scenarios such as roof photovoltaics, more roof area can be used to arrange photovoltaic equipment, improving the utilization effect of roof resources.

[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 1-Figure 3As shown, the utility model provides a factory ventilation and supplementary lighting device, including: a rotary exhaust device, which is installed through the factory roof 8; a power generation device, which is installed in the shell of the rotary exhaust device and connected to the rotating shaft 103 of the rotary exhaust device for generating electricity; a lighting device, which is installed at the lower end of the shell of the rotary exhaust device, connected to the power generation device, and is located on the inner side of the factory roof 8.

[0029] Specifically, the rotary exhaust device mainly ventilates and exhausts the factory by rotating the fan blades 101. The center of the fan blades 101 is connected to the rotating shaft 103. During the rotation of the fan blades 101, the rotating shaft 103 is driven to rotate synchronously, thereby driving the rotor of the power generation device to rotate synchronously to generate electricity. The rotating shaft 103 can be stabilized by the bearing 7.

[0030] The power generation device is mainly a generator 2. In this device, due to the volume limitation of the rotary exhaust device, the generator 2 needs to be selected to be smaller in size. Such a generator 2 is common in the prior art, such as a small generator 2 device in some hand-cranked generators 2, which can meet the use requirements. The rotating shaft of its rotor is connected to the rotating shaft 103 of the rotary exhaust device, and rotates synchronously to generate electricity.

[0031] The lighting device can be an LED lighting lamp 3, which requires a low working voltage, and the output voltage of the power generation device is generally sufficient to meet the requirements. The lighting device is connected to the area inside the factory building at the bottom of the rotary exhaust device to illuminate the interior of the factory building. Therefore, in fact, in this embodiment, the lighting device and the exhaust device jointly occupy the roof resources, rather than the lighting device and the exhaust device occupying the roof resources separately as in the prior art, so the device can reduce the occupied roof resources as a whole.

[0032] In addition, for a large area of ​​factory area, multiple exhaust devices are generally installed on the roof, so in this device, multiple lighting devices are also installed on the roof along with the exhaust devices, so the brightness of a single lighting device does not need to be very high to make the overall brightness in the factory area meet the requirements. Therefore, in this device, the size and power of the generator 2 may be small, but it is still enough to meet the low voltage requirements of the lighting device.

[0033] And from the perspective of maintaining the lighting brightness in the factory building, if the original lighting environment in the factory building is not changed, after adopting this device, the lighting environment in the factory building is significantly improved because the same number of lighting devices as the rotary exhaust device is added; in this case, for the factory building using segmented light-transmitting tiles, the arrangement of segmented light-transmitting tiles can be reduced, and the lighting environment in the factory building can still be maintained (through the compensation of the lighting device in this device). Therefore, the roof area resources are still increased.

[0034] In this way, due to the increase in roof area resources, in scenarios such as rooftop photovoltaic installation, more photovoltaic equipment can be installed on the roof, thereby improving the utilization of roof resources.

[0035] Example 2

[0036] like Figure 1-Figure 3 As shown, the rotary exhaust device is a non-powered hood 1. The non-powered hood 1 comprises a fan blade 101 and a neck tube 102, the fan blade 101 is rotatably mounted on the neck tube 102, and the neck tube 102 is fixedly mounted on the roof of the factory building.

[0037] Specifically, the unpowered wind hood 1 is also called a spherical ventilator or a natural ventilator. It is a prior art product and is widely used in the field of building ventilation. It can be purchased from online shopping websites or offline factories, and its structural principle will not be repeated. In this embodiment, the spherical fan blade 101 of the unpowered wind hood 1 is centrally connected to a rotating shaft 103 (in fact, this is also a structure that has been used in the prior art to maintain the rotation stability of the spherical cap), and the rotating shaft of the generator 2 is connected to the rotating shaft 103, so that the generator 2 actually generates electricity through wind power. The neck tube 102 is fixed on the roof of the building, and there is a circle of flat roof fixed waterproof strips and a circle of sloping roof fixed waterproof strips on it. The main body of the power generation device is fixed in the neck tube 102, and the main body of the lighting device is fixed at the lower end of the neck tube 102, located in the factory area.

[0038] Example 3

[0039] like Figure 1-Figure 3 As shown, the power generation device includes a generator 2, which is fixedly installed in the neck tube 102 of the unpowered hood 1 and connected to the rotating shaft 103 connected to the fan blades 101. The power generation device also includes a rectifier (not shown) connected to the generator 2. The power generation device also includes a battery 4 connected to the rectifier.

[0040] Specifically, this embodiment can use a similar generator such as a hand-cranked generator, which is small in size and sufficient to meet the voltage requirements of the LED lighting lamp 3. In addition, considering that the power generation of the generator 2 is related to the rotation speed, the generator 2 can also be accelerated by an acceleration gear, that is, a large gear is connected to the rotating shaft 103 of the unpowered hood 1, and a small gear is connected to the rotating shaft of the generator 2 and meshed with the large gear, thereby accelerating the rotation speed of the generator 2 and increasing the power generation. Of course, the large gear and small gear here are not limited to a single gear, but can also be a gear set structure.

[0041] In this embodiment, the rectifier is used to convert the AC power of the generator 2 into DC power, and then connect it to the battery 4. While the battery 4 provides DC power to the LED lighting lamp 3, the excess power is stored in the battery 4. When the power generation power of the generator 2 decreases, the battery 4 continues to supply power to the LED lighting lamp 3.

[0042] Example 4

[0043] like Figure 1-Figure 4 As shown, the lighting device is an LED lighting lamp 3. The LED lighting lamp 3 is electrically connected to the generator 2 and the battery 4. The LED lighting lamp 3 is fixed to the middle of the lower end of the neck tube 102 of the non-powered hood 1. The neck tube 102 of the non-powered hood 1 is surrounded by a ventilation channel 5.

[0044] Specifically, the LED lighting lamp 3 is a prior art product, and its structural principle is not described in detail. In this embodiment, the LED lighting lamp 3 can be directly connected to the generator 2 for power supply and lighting, or it can be indirectly connected to the generator 2 through the battery 4 for power supply and lighting. The LED lighting lamp 3 has low power consumption and low heat, which can avoid fire hazards. In the neck tube 102 of the unpowered wind hood 1, several support rods extend from the inner wall of the neck tube 102 to the middle part, which are used as fixed brackets 6 for the generator 2, the battery 4 and the LED lighting lamp 3, so that these devices are connected in the center of the neck tube 102. Then a ventilation channel 5 is formed around the neck tube 102, and the wind in the factory enters the neck tube 102 from the bottom of the neck tube 102 and is discharged. The center of the bottom of the neck tube 102 is the LED lighting lamp 3 to illuminate the factory.

[0045] Working mode and principle of this device:

[0046] By connecting a generator 2 inside a non-powered wind hood 1 on the roof of a factory building, power generation can be achieved through exhaust air; and an LED lighting lamp 3 is installed at a position inside the factory building at the lower end of the non-powered wind hood 1, so that self-generation is achieved to illuminate the factory building, and no external power supply and wiring are required, thereby reducing construction process installation and operating costs.

[0047] In the present device, the unpowered wind hood 1 and the LED lighting lamps 3 occupy a common area of ​​the factory roof, which reduces the occupied roof area resources as a whole; the number of LED lighting lamps 3 is relatively increased, thereby relatively reducing the roof structures with low bearing capacity such as translucent tiles, thereby increasing the available area resources of the roof, so that in application scenarios such as roof photovoltaic laying, more photovoltaic equipment can be arranged on the roof to improve the utilization effect of roof resources.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
