Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rounding device for removing mantle deposited on the roots of cliffs such as company houses.

In the past, especially in nuclear power areas, it was often necessary to remove snow that accumulated on the roofs of houses in the winter (so-called snow removal), and people had to go up to the rooftops to remove snow with shovels or shovels.
This is done by hand using tools such as the snow dumper 50 shown. However, this work of lowering one's head is extremely hard work, and accidents such as falls are more likely to occur, especially since workers have to go up to the roof when it is snowing, making it a big safety issue. Moreover, the difference in 1 & loss of tiles depending on the axial ratio.
There was also. Therefore, a method has already been considered to solve the heat bush device 1, but the idea is to install the electric heating device over a wide area of the roots, and the device 1J is large and complicated. ), expenses and consumption IIIti11. I couldn't imagine that the cost would be extremely high due to the charm of power.

The main station IIJ1 forest is located above 1i41h, so you can easily 11111 without going up to the roof when loading electricity! ! One of our objectives is to provide a snow removal device that is simple in structure and inexpensive.The roof of the building is covered with an air bag that can be compressed and stretched, and the air bag is In the contracted state, it has a thin plate-like shape that follows the rootlets, and in the active state, it is slanted to the extent that it does not accumulate on the upward movement of the blood vessel.

The second part is a vertical notch i in a part of the lowering device according to the present invention.
The original picture shows the time of 1/# Zhang.

An opening 3 of the air bag 5 is provided in the center of one of the openings 2 of the opening 4A, and the air device is kept airtight from the outside except through the opening 3. The mouth 3 is laid out integrally and is connected to the hose 4. , connected to an air pump 15 driven by an engine or the like. The Air Gin 1S is designed to forcibly supply and discharge pressurized air to and from the air bag IK by changing a switch. The air bag 1 is made of weather-resistant and cold-resistant material, especially flexible materials such as resin. The air bag l covers almost the entire top of the roof of the house! In the 2nd kl state, the approximately center of the lower surface 2 is concave upward corresponding to the ridge of the house, and the JII

It is designed so that it can be ridden. On the other hand, the upper IIS of the air bag L is

, is inclined downward from the center 6a toward both ends 7.8, and is set at an angle of iN to prevent lightning from accumulating on the upper surface 6 of the slope. Furthermore, inside the air bag l, there are a plurality of chambers 9.10110', 11, I1'#[! ljc parallel t
- By the gap I112 extending directly? The diversion chamber 12 is provided with a chamber 13 that communicates the two chambers. FIG. 3 is a diagram showing a state in which the thunderbolt device is installed in a house in a third-loop contracted state. Since the air device is made of a flexible material, it has the shape of a bedboard that smoothly follows the roof 14. The air pump 5U is connected to the air bag 1 via the hose 4, and is installed on the ground, and the narrow end 7.8 is attached to the eaves of the roof 14 with multiple bands to prevent the ridge 4A from being blown away by the wind. (not shown).

Next, the operation will be explained. Before the snowfall, as shown in Figure 3, the roof 14 was piled up and fixed with fat air bags ◎Due to the snowfall, there was a considerable amount of cod on the roof for 4 hours horizontally, making it necessary to do turtle hoofing. Sometimes, the air pump 5 is operated to pump air into the air bag lVc. Pneumatic pressure! I! It overcomes the weight of the air bladder l Hirotomi and begins to expand W#, but due to %IW12, the central chamber 9 (both shown in Figure 2) begins to expand, pushing Seal 15 towards the direction (j14tlKI). Further air is pumped into the air bag 1u, chamber 9 (1112tl, J), i-ra, and gradually inflates to plan 1011o' and chamber 11111' to 7.8, completely.・.

Since the upward direction 6 is set to have an inclination that prevents lightning from accumulating before it expands, it is very easy to use! All of the lIr deposited above falls on the negative side of the cliff (II5N)
. After completing the lowering after going through the state shown in Figure 5, the air pump 5
of! to forcefully discharge the air inside the air bag,
The air bladder 1 is brought into a deflated state (II). At this time, the series of IIPIIi+ from the 3rd to the 6th snowfall jkK
Depending on the situation, this may be done by manual operation of the switch of the air pump 5, or by connecting the tie i to the switch of the pump 5, periodically supplying air to the air bag 1 to inflate it, and then It is also possible to forcibly discharge and contract the air and automatically make snow fall.In addition, set a pressure switch that turns on when a set pressure is applied on the Kfil root 14, and make snow fall. It is also possible to automatically activate the switch of the pump 5, which is programmed to inflate and deflate the air bladder 1, by turning on the pressure regulator as the pressure increases.

As explained above, the present invention allows lightning to fall simply by changing the air bag l from the deflated state to the W can shape Imk without the need for a person to go up to the rooftop, which frees the person from the hard work of snowfall. It is possible to prevent dangers such as falling accidents, and also prevent damage to roof tiles due to tread pressure. And-
Since the structure is simple, the manufacturing cost of the device itself is low, and since the method of melting the seal is not used, the operating cost is also low.

The 7th figure is flat M! This is a section showing the case where the present invention is applied to the root. Air gl! 1 is made of a flexible material and is shrunk into a flat plate shape that smoothly covers the roof 14'. From the state shown in Figure 97, if a lightning storm becomes necessary, air is pumped into the air bag 1. As shown in Figure 8, the central chamber 9 first narrows the J11 tension, gradually expands while pushing the snow away, and finally expands completely as shown in Figure 91, and the slope of the upper surface 6 accumulates lightning. As a result, all the harm falls on Kojikata. At this time, the lower part 1ki2 of the air bag 1 is flat along the flat roof board, and there is no upward depression as in the embodiment shown in FIG.

In carrying out the present invention, the exposed base metal body of the base material on which tiles etc. are not placed is always covered with an air bag l, and 5kl of air is not only used to prevent water leakage, but also to prevent water leakage. It can also be used as a stop. W again! LkA includes a vinyl house, and when used in a vinyl house, the lower surface 2 of the air bag L is extended and the lower surface 2 is
It is also possible to form a thin roof over the entire greenhouse using Ii2 and provide the air bag 1 integrally with the roof. Furthermore, the substances introduced into the air gki are not limited to air.
Other gaseous substances may also be used, and foam-like substances may be injected. In addition to the method of introducing the substance into the air bag 1 from the outside, it is also possible to put a solid or wave body that starts to vaporize (by some stimulus) into the air bag 1 in advance and vaporize it when necessary. K to inflate air bag 1.
In the embodiment, the wh 1112 is extended almost parallel to the rod, and when inflated, the central 6 holes of the air bag 1 are configured to protrude upward, but the shape of the roof 14, 14' and the snow 15 Depending on the location conditions of the falling point, it is a gap! It would be good to legislate the placement of the highest protruding position of 12 and Retired Emperor 6.

The plow wall 12 can also be omitted.
