Description

Cylindrical solar power generation device {Cylinder Typed Generating Apparatus}

The present invention relates to a solar power generation device, and more specifically, to a cylindrical solar power generation device that is made into a cylindrical shape by bending a flat power generation module sheet into a cylindrical shape and then fixing it, which can then be fixed and installed on various pillars. will be.

Street lights are generally installed to illuminate roads. Here, street lights are structurally and functionally similar to security lights, so they can be used as a concept that includes security lights.

In general, street lights include a pole and a lighting device that is installed to hang on the top of the pole. Street lights are installed in a wide variety of places, such as alleys, parks, and driveways, and their size is determined by their specific use.

Meanwhile, research is being widely conducted to protect the environment by reducing the use of fossil fuels, and efforts to use clean energy such as solar energy are part of this effort. Therefore, lighting devices for lighting through solar power generation are becoming widely available. This solar-powered lighting device has the advantage of being economical and easy to install because it does not require external power supply.

However, in the case of using solar power generation, if there is little sunlight, the amount of power generation is insufficient and the light cannot be properly lit using only the power source. Also, since the conventional solar panel is in the form of a flat plate, the lighting device becomes bulky and there is a problem that it is structurally dangerous during strong winds.

Street lights should not be turned on irregularly depending on weather conditions. When installing wide plate-shaped solar panels on streetlights, it is not aesthetically desirable. For this reason, street lights using solar panels have not been widely distributed.

However, recently, solar power generation technology, which can generate power even with a small amount of light regardless of the amount of sunlight, has begun to spread. This is a technology that allows power generation not only in rainy weather but also at night when there are lights around. These circumstances indicate the possibility of developing street lights using solar power generation. The present inventor has filed a patent for incorporating solar modules with such performance into street lights.

However, according to this, since the installation pipe 17 is included, the weight of the device increases too much and it is very difficult for an operator to install it alone. Even if the installation pipe 17 is made of aluminum, a lightweight metal, the problem still remains.

Republic of Korea Patent Application No. 10-2013-0102321 Republic of Korea Patent Application No. 10-2014-0106861 Republic of Korea Patent Registration No. 10-2131843

In response to the above problem, the purpose of the present invention is to provide a cylindrical solar power generation device and a pillar such as a street light using the same. More specifically, by using flexible solar panels, the volume can be greatly reduced, and the solar panel has its own heat dissipation function and is light in weight, so workers can install it alone without much difficulty, and it can be used for a variety of purposes. The purpose is to provide a power generation device and a pillar with a power generation function using the same. Other purposes will be further specified through the explanation below.

The above purpose is,

A power generation unit including a flexible flat power generation module sheet and a terminal connected to the power generation module sheet; Includes; a fixing mechanism for fixing the power generation unit in a cylindrical shape;

The fixing mechanism is,

An inner support member in which a holder is installed at the center and a pair of inner support plates located on the same circumference on both sides of the holder are installed symmetrically left and right in a wing-like manner; and

There is an insertion portion in the center that is press-fitted into the holder, and on both sides of the insertion portion, a pair of outer support plates located on the same circumference are installed symmetrically like wings.

The power generation module sheet is achieved by a cylindrical solar power generation device in which only both ends of the power generation module sheet are fixed in a cylindrical shape by being respectively inserted into the space between the inner support plate and the outer support plate.

According to an embodiment of the present invention, the inner support district has a cross section of " It provides a receiving space in the form of ", and a locking protrusion is provided on the inner wall of the holder;

The outer support district has a cross section of " It may have a shape such as "and may include a pair of fingers with a rake-like end so as to be inserted into the receiving space of the holder and fastened to the locking protrusion.

The thickness of the inner support plate of the inner support district may be 1.1 to 1.3 times the thickness of the outer support plate of the outer support district.

According to another embodiment of the present invention, a thickness setting stand protruding and extending in the radial direction of the power generation module sheet is integrally connected to the inner wall of the holder;

The inner wall of the thickness setting table may be inclined to a point where the locking protrusion is provided to facilitate insertion of the finger.

According to the above configuration, the solar power module sheet, which has previously been used only in a flat form, can be used in a cylindrical form, thereby diversifying installation locations and greatly improving usability. In other words, it provides an opportunity to generate power by installing it on various pillars around the area, such as bollards, street lights, security lights, and traffic lights.

In addition, the cylindrical solar power generation device according to the present invention is light enough to be easily handled by one to two workers, so it can be easily installed anywhere, contributing to further popularizing solar power generation.

Hereinafter, specific details of the present invention will be described in detail with reference to the attached drawings. First, the description will be made with reference to FIGS. 1 to 7 simultaneously, and specific drawings will be cited where necessary.

The cylindrical solar power generation device according to the present invention has a cylindrical shape as shown. Recently, as the technology of solar power generation devices has developed, it has become possible to effectively generate power even without direct sunlight. Even at night, it has become possible to generate electricity by receiving ambient light.

The main body that generates solar power generation is the power generation module sheet. Currently, power generation module sheets are being produced and distributed by several companies around the world. There are differences in performance depending on the company.

Since the contents of the power generation module sheet (1) are public notices, detailed explanation is omitted. The power generation module sheet 1 is basically flexible and has a stacked structure, so it has a predetermined thickness. Even if the power generation module sheet 1 is flexible, the length (L) is 1 to 2 m, the thickness (T0) is 2 to 3 mm, and it is rigid, so it does not bend very easily. If pressure is applied incorrectly during the bending process, damage may occur and the power generation function may deteriorate.

Even if you carefully bend it into a cylindrical shape and then fix both ends, it is difficult to keep it fixed due to its own elasticity. This is because during the process of use, various problems occur, such as the fixed part opening or bursting due to deterioration due to its own elastic resilience or solar heat.

In response to this problem, the present invention proposes a fixing mechanism (3) and a fixing method for bending the power generation module sheet (1) roundly and then fixing only both ends to maintain a cylindrical shape. This fixing mechanism 3 and fixing method were completed through much trial and error by the present inventor.

The flexible flat power generation module sheet (1) together with the terminal (5) constitutes one power generation unit (7). The generated electrical energy is supplied to various types of consumers through the terminal (5).

The fixing mechanism (3) is a means for maintaining the stiff but flexible power generation module sheet (1) fixed in a cylindrical shape. The fixing mechanism 3 includes an inner support member 9 and an outer support member 11 that are coupled to each other.

At the center of the inner support district (9), the cross section is " There is a holder 13 in the shape of ", and a pair of inner support plates 15 and 17 are installed on the same circumference on both sides of the holder 13. The inner support plates 15 and 17 are holders (like wings). It is installed symmetrically on the left and right around 13).

Each width (W) of the inner support plates 15 and 17 may be adjusted depending on the rigidity of the power generation module sheet 1, but may be 30 to 100 mm. That is, the inner support plates 15 and 17 support the ends of the power generation module sheet 1 over a large area. The inner support member 9 has sufficient rigidity to prevent shape deformation from occurring due to the restoring force of the power generation module sheet 1.

At the center of the outer support 11, there is an insertion portion 19 that is press-fitted into the holder 13, and on both sides of the insertion portion 19, a pair of outer support plates 21 and 23 are located on the same circumference. ) is installed. The outer support plates 21 and 23 are also installed symmetrically around the insertion portion 19 like wings.

The inner support member 9 and the outer support member 11 are installed along the entire length of the power generation module sheet (1). However, it may be installed over the entire length of the power generation module sheet 1, leaving a portion for installing the upper fastening ring body 41 and the lower fastening ring body 43, which will be described later.

It is a part that is manufactured by extrusion or drawing from metal or synthetic resin and has a constant cross-sectional shape along the longitudinal direction. The inner support member 9 and the outer support member 11 are preferably made of aluminum.

The insertion portion 19 of the outer support member 11 may be press-fitted into the holder 13 of the inner support member in a male-female combination manner to be assembled and fixed. It is preferable that the inner support part 9 and the outer support part 11 are coupled in a semi-permanent fastening method that cannot be separated by general methods once they are inserted. The inner support member 9 and the outer support member 11 are coupled with both ends 1a and 1b of the power generation module sheet in between. That is, both ends (1a, 1b) of the power generation module sheet are respectively inserted and fixed into the space between the inner support plates (15, 17) and the outer support plates (21, 23).

According to an embodiment of the present invention, the inner support member 9 has a cross section of " It provides a receiving space (S1) that is opened upward in the form of ". A locking protrusion (25) is provided in the downward direction on both inner walls of the holder (13) of the inner support member (9).

The outer support district (11) has a cross section of " It has the same form as " and includes a pair of fingers 27 with claw-like ends (or dovetails) so that they are inserted into the receiving space (S1) of the holder (13) and fastened to the locking protrusion (25). This can be done. The finger 27 is elastically compressed by press-fitting and is 'clicked' on the locking jaw 25. Therefore, once coupled in the coupling direction, it cannot be separated by normal force.

According to an embodiment of the present invention, the average thickness (T1) of the inner support plates (15, 17) of the inner support member (9) is relative to the average thickness (T2) of the outer support plates (21, 23) of the outer support member (11). It may be 1.1 to 1.3 times. The fingers 27 are equal to the thickness of the outer support plates 21 and 23.

According to this thickness ratio, the inner support member 9 strongly contributes to supporting the shape of the power generation module sheet 1, and the outer support member 11 flows elastically to some extent and adheres to the inner support member 9. It becomes possible to combine.

Meanwhile, thickness setting tables 29 and 31 protruding and extending in the radial direction of the cylindrical power generation module sheet 1 are integrally connected to the inner wall of the holder 13. The inner walls 29a and 31a of the thickness setting tables 29 and 31 may be inclined to a point where a locking protrusion 25 is provided to facilitate insertion of the fingers 27.

At the top of the thickness setting table (29, 31), reinforcing bars (33, 35) protrude and extend outward from the receiving space (S1). The reinforcement bars 33 and 35 are for maintaining rigidity.

An inner adhesive layer 37 may be interposed between the upper surfaces of the inner support plates 15 and 17 and the inner surface of the power generation module sheet 1. Additionally, an outer adhesive layer 39 may be interposed between the bottom of the outer support plates 21 and 23 and the outer surface of the power generation module sheet 1. The inner adhesive layer 37 and the outer adhesive layer 39 can be provided by applying adhesive or using double-sided adhesive tape.

According to an embodiment of the present invention, an upper fastening ring body 41 and a lower fastening ring body 43 may be installed at the upper and lower ends of the cylindrical power generation module sheet 1, respectively. The upper fastening body 41 is inserted and fixed to the top of the power generation module sheet 1. The upper fastening ring body 41 may include various fixing means to be fixed to the outer peripheral surface of the column body 45 (see FIGS. 5 and 6). The upper fastening ring body 41 and the lower fastening ring body 43 can be fixed to the power generation module sheet in various ways, such as adhesive or rivets.

The lower fastening body 43 is inserted and fixed to the lower end of the power generation module sheet 1. The lower fastening ring body 43 may include various fixing means to be fixed to the outer peripheral surface of the column body 45.

These fixing means may be bolts, clamps, bands, adhesives, or welding.

The upper fastening ring body 41 and the lower fastening ring body 43 serve as a medium connecting the power generation module sheet and the pillar body 45. The upper fastening ring body 41 and the lower fastening ring body 43 may be provided with ventilation holes 47 and 49 to allow air to communicate in the vertical direction.

Detailed description of the upper fastening body 41 and the lower fastening ring body 43 will be omitted as reference may be made to the contents of Korean Patent Registration No. 10-2131843 registered by the present inventor.

Hereinafter, the state of use of the present invention will be described with further reference to FIGS. 5 to 7. As shown, the power generation pillar uses a cylindrical power generation device according to the present invention. A power generation pillar as shown is provided by fixing and installing a cylindrical power generation device on the outer periphery of the pillar 45. The power generation pole here is a street light with a power generation function.

Meanwhile, a connector ring 51 may be installed so that the power generation module sheet 1 can be continuously connected and used in the longitudinal direction. The connector ring 51 is provided with power generation module sheet coupling portions 53 and 55 in the vertical direction. This connector ring 51 is used when connecting the power generation module sheet 1 in the longitudinal direction according to the length of the pillar 45.

It is natural that the cylindrical solar power generation device according to the present invention is installed using a predetermined pillar 45. This pillar 45 can be very diverse, such as street lights, landscape lights, security lights, CCTV installation stands, electric poles, bollards (vehicle entry prevention devices installed on the road), and traffic lights. The uses of the generated power can be very diverse, including light bulbs, CCTV cameras, household, industrial, anti-icing heaters, and traffic lights.
