Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mobile sprinkler system that is useful not only when the roof of a building has a rigid structure but also when the roof is a non-rigid structure.

[Conventional technology]

When the roof of a building is a non-rigid structure, such as an air membrane structure, water sprinkling is used to melt snow accumulated on the roof or to lower the temperature of the membrane surface of the roof. When installing the equipment, conventionally the flexible piping of the sprinkler system was fixed with a joint fitting provided on the air membrane surface, or if the flexible piping could not be fixed directly to the membrane surface, it was fixed from both sides of the roof. A configuration was considered in which a long-span support arm was installed above the roof to support the flexible piping.

[Problem that the invention attempts to solve]

However, in the former case with such conventional configurations, the weight of the flexible piping and water sprinkler is loaded onto the membrane surface, so it is necessary to increase the air pressure within the membrane surface to accommodate this load. For this purpose, extra driving power of the pressurizing blower is required. Furthermore, there is a possibility that the flexible pipe acts as a snow stopper for the membrane surface, causing uneven load on the membrane surface. Furthermore, there are other problems such as the fact that it is difficult for the flexible piping fixed to the joint fitting to sufficiently respond to changes in tension on the membrane surface due to changes in pressure within the membrane surface.

In addition, in the latter case, since the support arm has a long span, the erection structure will be huge in terms of its own structural strength and strength against wind pressure, and the problem is that the construction cost is expected to increase. There is.

This invention was created by focusing on these conventional problems, and aims to be lightweight, reduce the load on the roof, solve the above problems, and make it applicable to rigid roofs. It is an object.

[Means for solving problems]

This invention is a mobile watering equipment that moves over the roof of a building and sprays fluid at a desired location.
A cable installed in a reciprocating manner in a direction across the roof of a building; a fluid ejecting device fixed to the cable and ejecting pressurized fluid onto the upper surface of the roof;
The present invention is characterized by comprising a cable drive device connected to the cable and reciprocating the fluid ejecting device by reciprocating the cable.

[Effect]

In the mobile watering equipment of the present invention, when the cable drive device is driven, the cable drive device starts moving the cable, so the fluid ejecting device fixed to the cable is Moved in the direction of movement.
During this movement, the fluid ejecting device ejects fluid onto the upper surface of the roof, or by stopping at a certain position, the fluid is ejected at this position to melt snow on the roof or cool the roof.

〔Example〕

This invention will be explained below based on the drawings. 1 to 6 are diagrams showing an embodiment of this invention.

First, to explain the structure, 1 is a building, and 2 is a roof with an air membrane structure provided on the top of this building 1.

Reference numerals 3 and 4 shown in FIGS. 1 and 2 are a pair of winding mechanisms provided on both side edges of the roof 2 in the transverse direction, and these constitute the cable drive device of the present invention. . These winding mechanisms 3 and 4 are shown in FIG.
As shown in Figure 4, they have the same structure,
Each of them is provided with two winding drums 16 and 17 having the same diameter, and a drive source 15 such as a motor that rotates the winding drums 16 and 17 simultaneously in the same direction. Note that the positions of these winding mechanisms 3 and 4 do not necessarily have to be on the roof.

5 and 6 shown in FIGS. 1 and 2 are installed parallel to the direction across the roof 2 between the two winding mechanisms 3 and 4, and both ends are connected to both winding mechanisms 3 and 4. It is a cable such as wire rope. These cables 5, 6
As shown in FIGS. 5 and 6, it is guided on a guide pulley 7 that is rotatably supported by a bracket 14 that projects upward from the roof 2, and is movable back and forth in the installation direction. be. As shown in FIGS. 3 and 4, both ends of one cable 5 are attached to one winding drum 16 of each winding mechanism 3, 4.
Both ends of the other cable 6 are wound around the other winding drum 17 of each winding mechanism 3, 4 in opposite directions. As a result, either one of the winding mechanisms 3, 4
When the drive source 15 is rotated, the two cables 5 and 6 are wound in the same direction and at the same speed, thereby moving the two cables 5 and 6 in parallel. Although wire ropes are used as the cables 5 and 6 in this embodiment, a single wire or a stranded wire other than metal may also be used. Also, belts, chains, etc. may be used.

Reference numeral 8 shown in FIGS. 1 and 2 is a fluid ejecting device, which is suspended from the two cables 5 and 6 to
It is fixed by 2. This fluid ejecting device 8
is composed of a water spray pipe 11 arranged perpendicularly to the cables 5 and 6, and a plurality of injection nozzles 13 arranged in the longitudinal direction of the water spray pipe 11.
A flexible hose 9 for water supply is connected to the water sprinkler pipe 11.
are connected to each other so that fluid supplied under pressure from a water pump 10 provided below the roof 2 is jetted onto the roof 2 from the jet nozzle 13.

Next, the effect will be explained.

Among the pair of winding mechanisms 3 and 4, for example, the drive source 15 of the winding mechanism 3 on the left side in FIGS. 1 and 2
When the winding drums 16 and 17 are rotated, the winding drums 16 and 17 begin to rotate in the same direction, and simultaneously begin winding up the cables 5 and 6 wound on each other in the same direction. There, cables 5 and 6
are moved in parallel to the winding mechanism 3 side, and the fluid ejecting device 8 fixed thereto is also moved in the same direction. At this time, since the drive source 15 of the other (right side) winding mechanism 4 is inactive, the cables 5 and 6 that have been wound around the winding drums 16 and 17 of this winding mechanism 4
is automatically pulled out by the rotational force of the drive source 15 of the winding mechanism 3. and fluid ejection device 8
When the water reaches a desired position on the roof 2, by stopping the drive source 15 of the winding mechanism 3, water can be sprinkled at that position. Further, a fluid ejection device 8
When moving in the opposite direction, the driving source 15 of the winding mechanism 3 is stopped and the driving source 15 of the opposite winding mechanism 4 is driven, thereby performing the same operation as described above.

In addition, the sprinkler pipe 11 includes a PVC pipe and cables 5 and 6.
By using a material with high tensile strength and a small cross-sectional area, and a rubber hose etc. for the flexible hose 9 to reduce the weight of the equipment, the load on the roof 2 can be reduced, and the air membrane structure can be used to reduce the weight of the equipment. formed roof 2
There is no need to particularly increase the internal pressure of the.

Further, in the above embodiment, two winding mechanisms 3 and 4 forming a pair are arranged at both edges of the roof 2, and both ends of the two cables 5 and 6 are connected to each winding mechanism 3 and 4.
However, depending on the structure of the fluid ejecting device 8, the cables 5 and 6 may be formed in an annular shape as shown in FIG. The cable may be hooked onto a winding mechanism 19 provided at only one edge of the roof 2 and capable of rotating in forward and backward directions, and a pulley 20 provided at the other edge of the roof 2. In this case, the fluid ejecting device 8 can be moved between both sides of the roof 2 by normal and reverse rotation of the winding mechanism 19.
