Description

Modular rollable heating screen device {MODULE TYPE ROLLABLE HEATING SCREEN DEVICE}

The present invention relates to a modular rollable heating screen device.

Accidents frequently occur where buildings collapse due to the weight of snow accumulated on roofs due to heavy snowfall in winter, or when snow accumulated on buildings or icicles formed on exterior walls fall to the ground, injuring pedestrians or damaging parked vehicles. . For example, in the case of structures with curved roofs without internal heating wires, accidents due to accumulated snow are more frequent. Although people can climb up and clear the snow themselves, the risk of falling accidents remains, and additional costs for the work are incurred. generates

Accordingly, recently, due to heavy snowfall in the winter and an increase in the number of cold days, various types of heat generation technologies have been widely applied to daily life and industrial sites. In particular, products in the form of standardized panels are mainly used for various types of outdoor infrastructure structures due to issues such as ease of installation and durability.

When applying the currently used heating panels, installation costs increase because they must be manufactured in the shape of the roof, and there are difficulties such as the cost of management and removal when not in use. Additionally, if left exposed outdoors during a period of non-use, the durability of the panel will be affected due to deterioration in the high temperature environment in the summer.

In other words, most of the heating panels currently in use are finished with materials with low flexibility, so in order to apply them to structures with low flatness such as curved surfaces, the panels must be individually manufactured to fit the shape of each structure in the initial molding stage, resulting in an increase in installation costs. There is a following problem.

Republic of Korea registered patent 10-1592519 (Title of invention: Functional roof structure to prevent building collapse due to snow load)

The present invention is intended to solve the problems of the prior art described above, and seeks to provide a modular rollable heating screen device using a new heating technology that can be easily attached and removed regardless of the shape of the applied structure.

However, the technical challenge that this embodiment aims to achieve is not limited to the technical challenges described above, and other technical challenges may exist.

As a technical means for achieving the above-described technical problem, according to an embodiment of the present invention, a modular rollable heating screen device includes a housing disposed in one area of the structure and having an accommodation space therein; A cylindrical fixed shaft having a pair of ring-shaped electrodes at both ends and including a wire for connecting an external power source connected to the ring-shaped electrodes; A rotating hollow shaft arranged to surround the outer peripheral surface of the cylindrical fixed shaft and accommodated in the housing; A heating film wound with one end fixed to the outside of the rotating hollow shaft; and a pair of conductive metal brackets that electrically contact the electrode provided in the heating film with the annular electrode portion of the cylindrical fixed shaft, wherein the metal bracket is coupled to the rotating hollow shaft.

The heating film is sequentially laminated with an insulator, an electrode, a heating layer, and a finishing material to protect the heating layer.

The electrodes are arranged to match the direction in which the heating film is unwound from the rotating hollow shaft, and are a pair of plate-shaped electrodes provided on both sides of the heating film.

The heating layer is composed of a plurality of heating elements spaced apart from each other perpendicular to a pair of electrodes, and both ends of the heating elements are disposed on top of the pair of plate-shaped electrodes.

The heating film includes a rod perpendicular to the direction of unwinding from the rotating hollow shaft, and the rod is arranged to correspond to the rotating hollow shaft and the other end of the non-fixed heating film to keep the heating film taut.

The heating film includes a handle provided in one area of the other end and one or more holes for fixing the heating film.

The cylindrical fixed shaft is formed in one area at both ends and includes a slit groove cut from each end toward the center, and the annular electrode portion surrounds the cylindrical fixed shaft in a clockwise or counterclockwise direction on the outer surface of the cylindrical fixed shaft adjacent to the slit groove. It includes a formed annular region and a bent end that extends from the annular region and is bent to penetrate the slit groove and come into close contact with the inner surface of the cylindrical fixed shaft.

The wire for external power connection is fixed in contact with the bent end. The rotating hollow shaft is formed from an insulating material.

The metal bracket includes an upper member disposed on the outer surface of the rotating hollow shaft and in close contact with the heating film; a lower member formed to correspond to the upper member and in close contact with the inner surface of the rotating hollow shaft; N first protrusions provided on the lower surface of the upper member and formed to have a space apart; and N-1 second protrusions provided on the upper surface of the lower member and formed to have a space apart, wherein the first protrusion is formed at a position corresponding to the space apart from the second protrusion, and the second protrusion is formed at a position corresponding to the space apart from the first protrusion. It is formed at a position corresponding to the space space between the protrusions.

When the metal bracket is coupled to the rotating hollow shaft, the upper and lower members are brought into close contact with each other, and the first and second protrusions are in close contact with the space spaced apart from each other and penetrate the heating film and the rotating hollow shaft.

The upper member and the lower member include a first region and a second region, wherein the first region includes a connected connection portion of the upper and lower members, the second region has the upper and lower members spaced apart by a spacing groove, and the first region includes a first region and a second region. and an area where the second protrusion is disposed.

The housing is formed in a rectangular box shape and includes slit grooves corresponding to the longitudinal direction, and the heating film passes through the slit grooves and is discharged to the outside of the housing.

According to the problem-solving means of the present invention described above, unlike heating wires or heating panels that require major construction, installation and removal are easy, so it can be used only when necessary, such as during heavy snowfall in the winter, and can be removed and stored when not in use.

Since it is stored in the housing for periods of non-use other than the winter, it is possible to fundamentally solve the problem of durability deterioration due to direct sunlight, etc., which is a disadvantage of the existing fixed installation method (e.g., low heat generation performance, shortened lifespan), and as a result, it is possible to save money for a long period of time at low cost. It is possible to use.

Because the method covers the structure by spreading the film wrapped around a rotating hollow shaft, the installation time is short, allowing quick installation even after snow begins to fall, enabling rapid response to heavy snow damage.

Additionally, electrical contact between the rotating hollow shaft and the cylindrical fixed shaft can be maintained using the metal bracket according to an embodiment of the present invention.
