Description

The present invention relates to a technique for automatically removing snow within a predetermined range without requiring human power, and in particular, snow can be removed from a roof of a building toward an adjacent target range. In addition to the field of manufacturing and providing snow removal equipment, materials required for materials, machinery and parts from the field of providing and selling equipment and equipment necessary for its transportation, storage, assembly and installation For example, the field of providing wood, stone, various fibers, plastics, various metal materials, etc., the field of electronic components incorporated in them, the field of control-related equipment integrating them, the field of various measuring instruments, the equipment and instruments Fields generally called industrial machines, such as the field of power machinery to be moved, the electric power that is energy and the energy and energy fields that are the energy source, and the equipment, instruments, etc. Research, field related to display, sales, import / export, general or related to the results of their use and the collection and transportation of garbage debris generated by the operation of equipment and equipment There are not many technical fields that are not related to the fields, such as the recycling field that efficiently recycles garbage waste, and new fields that cannot be envisaged at this time.

(Points of interest)
To date, snow that has fallen in large quantities on the roof of a building has no effective means other than removing snow by snow removal work that relies on human sea tactics. It is necessary to prepare for a large burden of securing human resources and raising costs, and if heavy snow that contains moisture continues to accumulate in large quantities like every day, snow removal will not be in time, and many houses will collapse There are many problems related to human life, such as being exposed to crisis, and accidents that fall during snow-lowering work on the roof.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as typified by what is proposed in the following Patent Document 1 (1), the rail reaches a building roof from the ground, lays a rail around the entire roof surface, and runs along the rail. And a snow removal device provided with a traveling type snow remover capable of removing snow, or a guide rail parallel to the inclined direction of the building roof surface as seen in Patent Document 1 (2). A snow scraper made up of a pair of wipers that can run up and down in the middle of the rope arranged along the rail, opens automatically under the resistance of snow accumulation during descent, and automatically closes during ascent It is installed and travels up and down on the guide rail with the rope to be pulled, and the snow wiper of the roof that makes it possible to remove snow on the roof surface of the building, or the flow of the roof surface as in Patent Document 1 (3) Multiple roof surface lengths in the direction perpendicular to The booth is divided into booth areas, and ropes are installed on the guide frames provided on both sides of each booth area so that they can be rotated or reciprocated. The snow removal device fixed to the drive is driven by the control of the drive control device, and the drive control is performed so that the entire surface of the snow receiving sheet is covered with the snow falling edge from the position where the snow receiving sheets are covered with the snow sequentially covering the booth area. Drive until it returns to its original position again, and periodically drive the snow receiving sheet for each booth area sequentially at a time interval where the snow accumulation on each snow receiving sheet does not reach the set thickness. There are some examples of methods and devices for snowing buildings that are supposed to be operated.

However, the snow removal devices as shown in the former patent document 1 (1) are difficult to control the direction of snow removal of a snow removal machine that blows off the snow while running on the roof surface of the building. It is not possible to set the direction of snow removal, pay attention to the falling snow mass until the snow removal work on the roof is finished, and after the snow removal on the roof is completed, The snow shovel wiper of the roof of Patent Document 1 (2), which required snow removal work by human sea tactics in almost the entire area, was installed on a roof with a downward slope, and the wiper with an opening / closing mechanism slightly reduced snow accumulation. It is possible to scrape snow so as to apply a strong force and to cause snow to slide down, and the lower end (eave) of the down slope where snow drainage is trapped must be equipped with ridges, pulleys, drive pulleys, etc. The snow that falls down to the drive train What is represented by the method for snowfalling a building and its apparatus in the latter patent document 1 (3) is that the snow receiving sheet covering the roof is moved toward the roof eave. Because it has become, it will be snow removal and falling to the surrounding site under the eaves of the building, and the snow collected around the building thus leaves a fatal drawback that it will be drained by human sea tactics Met.

(Awareness of problems)
As mentioned above, the snow removal techniques on various roofs that have been proposed in the past all remove snow by dropping the snow on the roof around the building. There is a risk of falling snow in surrounding hot water facilities, warehouses, adjacent buildings, parked vehicles, passing people, etc., and when snow is removed from the building site, it is collected along the surroundings of the building. However, it has the disadvantage that it must be drained, and it is not supposed to be used for roofs with solar panels or skylights. With the configuration to make it possible to remove snow and collect it in the snow drainage section set at the appropriate location around the building, and to greatly reduce the burden of snow removal work, it has become possible to realize the possibility of further improvement. It is a thing.

(Object of invention)
Therefore, the present invention makes it possible to remove snow on the solar panels and skylights safely and reliably, and to make it possible to automatically remove snow so that it can be accumulated in a snow removal section set around a building. Judging from whether it is possible to develop snow removal technology, we started the development and research very quickly, and as a result of repeated trial and error over many years and many trials and experiments, this time we finally have a snow removal device with a new structure. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As clearly understood from the embodiments representing the present invention shown in the drawings, the snow removal device of the present invention basically comprises the following configuration.
That is, at the left and right ends of the snow removal target front facing the snow removal section adjacent to a part of the snow removal target range plane, the length, vertical posture, and predetermined height that can be passed over the entire width of the snow removal target range plane. From the stand-by state of supporting the left and right ends of the snow removal zone having a soft blade and at least one grounding support ring at the lower end edge, and arranging the snow removal zone at the deepest depth position of the snow removal target area plane. A snow removal device having a gist of a configuration including a pair of left and right traction / return mechanisms for guiding snow removal to a snow removal posture facing a snow removal target front and returning the snow removal posture to a standby state.

    The snow removal device having this basic configuration is more specifically described as follows: from the deepest depth position, which is one end of the rectangular snow removal target range plane, to the other end of the snow removal target range plane, A belt with a length, a vertical posture, and a predetermined height that can be passed to the width between the left and right sides of the snow removal target area plane on each of the left and right sides leading to the snow removal target front facing the snow removal section adjacent to the bottom edge A snow removal target frontage from a standby posture in which the left and right ends of the snow removal belt having a soft blade and at least one grounding support ring are supported in a stretched manner, and the snow removal belt is disposed at the deepest depth position of the snow removal target area plane. The snow removal device has a configuration in which a pair of left and right traction / return mechanisms for guiding snow removal to the snow removal posture facing the vehicle and returning to the standby state from the snow removal posture are provided.

If the expression is changed, the snow removal target front of the snow removal target range plane is excluded from the left and right ends of the snow removal target front facing the snow removal section adjacent to a part of the polygonal or irregular snow removal target range plane. Snow removal having a length, vertical posture, and a predetermined height of a belt that can be arranged along a plane contour, and having a soft blade at the lower edge and a number of grounding support rings corresponding to at least the number of corners of the snow removal target area plane The right and left edges of the belt are supported so that they can be wound and unfolded around the vertical axis, and the midway range between the left and right edges of the snow removal belt is on the entire periphery that reaches the deepest depth of the snow removal target plane, excluding the snow removal target front. A traction mechanism that can be rolled up from the standby posture to the snow removal posture facing the snow removal target frontage and that can be deployed from the snow removal posture to the standby posture when the snow removal guidance is stopped is provided. The depth of the range plane is the key point on the outer periphery. In addition, there is provided a return mechanism that elastically pulls and urges a plurality of appropriate locations in the midway range between the left and right ends of the snow removal zone, and automatically guides the snow removal posture to the standby state in accordance with the deployment operation of the traction mechanism. A snow removal device having the structure as described above is obtained.

    As described above, according to the snow removal device of the present invention, unlike the conventional one, the snow accumulation on the snow removal target range plane is adjacent to a part of the snow removal target range plane from the unique characteristic configuration as described above. Since it is possible to remove and accumulate snow automatically and efficiently toward the snow removal section, it is easier to load on trucks after removing snow compared to snow removal technology that removes snow everywhere. In addition to being able to make it extremely high, installing on the roof of a building eliminates the need for any dangerous work at high places, ensuring high safety, and solar installed on the roof Even if it is a solar panel installed in a house in a snowy area, the snow layer adhering to the surface of panels and skylights will be removed and the glass surface will not be damaged. Not The efficiency can be increased stably, and lighting from the skylights can be obtained. In addition, it is possible to reliably prevent damage from snow on buildings and solar panels, and to greatly reduce power consumption. The obtained characteristics can be obtained.

    In addition, the grounding support ring provided in the snow removal zone can safely overcome some steps between the roof top surface and the solar panel frame, etc., so durability is maintained without applying unnecessary stress to the soft blade. It can be remarkably raised, and it can be easily installed and used even on snow removal target area planes with complicated shapes by adopting a traction mechanism that winds the left and right ends of the snow removal belt around the vertical axis. Until then, it was necessary to transport and remove snow with complicated shapes, such as rooftops, to accumulate in the snow drainage area adjacent to a part, especially by human tactics. It eliminates the danger of work and a large labor burden, and exhibits the effect of being able to remove and accumulate snow quickly and efficiently.

    In the case where a guide rail is laid on the plane running locus of the snow removal target range of the grounding support ring of the snow removal zone, the guide rail base end is pivotally mounted near the standby position, and the tip end of the guide rail is directed to the snow discharge target frontage. By providing a trajectory adjustment mechanism that can change the direction as appropriate, each grounding support wheel can be guided more reliably toward the snow discharge target frontage, so that the movement of each grounding support wheel is balanced with each other. When there is a grounding support wheel that is difficult to travel, it is possible to change the direction of the tip of the guide rail by manipulating the track adjustment mechanism and make it smoother. There is an advantage that the track of the ground support ring can be freely adjusted to remove snow.

    If the snow removal belt is made of at least one of a translucent synthetic resin belt and a net belt, it may interfere with daylighting when installed on a building roof with solar panels or skylights. Without reducing power generation efficiency, it is possible to realize the same lighting as when there is no snow before installation, and the soft blade of the snow removal zone has a resilient urging portion, The one that is elastically movable in and out of the snow removal target area plane is advantageous for the soft blade to overcome the step between the roof surface and the solar panel, skylight, etc. It will follow the difference in elevation, keep the remaining snow to a minimum, and will exhibit outstanding snow removal capability.

The towing / returning mechanism has a drive source for snow removal guidance and return guidance, and a control device for the drive source, a wireless communication device is provided in the control device, and remote control by a portable terminal device having a wireless communication function What can be operated can further simplify the operation of the snow removal device of the present invention, using not only from the vicinity of the snow removal site, using a portable terminal device that is used daily, It will be possible to remotely control from a remote location through various information communication networks, and it will have a great effect that it will be more convenient.
