Description

  The present invention is a watering device for a roof that sprays water on a roof of a building having a gradient in which water flows down in a house, factory, etc., and particularly an injection nozzle from a high position on the extended line side of a roof ridge part away from the building It is related to the water sprinkling device of the roof that discharges water above the roof ridge, and cools the heated roof to lower the room temperature, prevents the spread of fire in the case of a fire in the neighboring house, It is possible to remove snow.

As this type of roof sprinkler, for example, as disclosed in Patent Documents 1 and 2 and the like, there is a proposal to sprinkle water on the roof of a building and cool it with vaporization heat, thereby suppressing an increase in room temperature. However, in these watering devices, watering pipes having a large number of water outlets arranged in parallel along the roof ridge portion are piped, and water is sprayed along the roof gradient from each water outlet.

Further, as disclosed in, for example, Patent Documents 3 and 4, etc., as in the case of Patent Documents 1 and 2, etc., hot water is supplied to watering pipes that are piped along the roof ridge, and the roof is melted by melting snow. There is also a proposal to remove snow.
Japanese Patent No. 2900743 JP 2000-257304 A

Furthermore, as disclosed in, for example, Patent Documents 5 and 6, a water discharge device is installed on the ground away from the building so as to operate in the event of a fire, and water is discharged from the ground to the roof by a spray nozzle. There are also proposals to prevent or spread fires.
Japanese Patent No. 3212741 Japanese Patent Laid-Open No. 9-19510

  However, when piping a sprinkler pipe along the roof ridge as in Patent Documents 1 to 4, it is necessary to perform installation work on the building, so the construction period becomes long and the cost increases. If water outlets with many small-diameter holes are installed in parallel to sprinkle the entire area of the roof, clogging may occur due to dirt, etc., and the water pressure decreases at a position away from the water supply side of the water spray pipe. Therefore, there is a problem that requires solutions such as the possibility that uniform watering cannot be performed over the entire area of the roof and that the building may be deteriorated due to water leakage from the piping.

  In addition, when the roof is cooled using prior art that discharges water from the ground as in Patent Documents 5 and 6, or when the roof is removed by melting snow by supplying hot water, the gap between the tiles and the tiles The roof is blown up by the water, or the roof is sunk in the field plate under the roof, and the roof may be damaged. There were issues that needed to be resolved, such as fear.

  Therefore, the present invention provides a roof watering device that can solve these problems of the prior art, and in particular, by the injection nozzle from the high position on the extended line side of the roof wing part away from the building, It is possible to perform installation work without adding a hand to the building by adopting a form in which water is discharged upward and water is uniformly distributed over the entire roof without damaging the roof. Made possible.

  The water sprinkling device for roof according to the present invention has a water supply pipe standing from the ground at a high position on the extended line side of the roof ridge part away from the building, the lower end side of the water supply pipe is connected to the water supply source, and the upper end of the water supply pipe On the side, an injection nozzle was installed that sprayed and sprayed water above the roof ridge with an elevation angle.

  In addition, the water supply pipe in the above-mentioned water sprinkling device of the roof is provided with an on-off valve that opens and closes the flow path and varies the flow rate and water pressure so that water can be discharged from one end side to the other end side of the roof ridge. Can be taken.

  According to this roof sprinkler, the high-pressure water discharged from the spray nozzle falls in a distributed state from the top of the roof onto the roof ridge while drawing a parabola, and then sprinkles along the sloped roof and flows down to the ridge. However, the radiant heat of the roof is taken away during this watering and cooling is done by vaporization heat, so it is possible to suppress the temperature rise inside the building and to prevent the spread of fire by this watering and to remove snow by melting snow. Is possible.

  In particular, since the water spraying device is provided at a position away from the building so that the spray nozzle discharges water from the high position on the extended line side of the roof building portion, the water spraying device is installed on the roof building portion. The installation work can be done inexpensively and easily in a short period of time without modifying the building as in the prior art, and there is no internal piping, so that the building can be prevented from deteriorating due to water leakage. Even in the case of a building having a different part length or other roof structure, a common watering device can be used, so that it can be mass-produced and provided at low cost.

  In addition, since water is sprayed in a dispersed state by directly discharging water from the spray nozzle, the water outlet is clogged with scales or the like, as in the prior art in which water is sprayed with a large number of small diameter holes. In addition, there is no fear that the water pressure is lowered at the water outlet that is away from the water supply side, and it is possible to maintain uniform watering over the entire area of the roof over a long period of time.

  In addition, there is no risk of damaging the roof by blowing up tiles as in the conventional technology that discharges water from the ground, or damaging the roof by damaging the ground plate under the tiles. Therefore, the water discharge is dispersed in the form of a mist when subjected to moderate wind pressure by a weak natural wind, and uniform watering can be performed over the entire roof.

  In addition, if the form is provided with an on-off valve that opens and closes the flow path and varies the flow rate and water pressure so that water can be discharged from one end side to the other end side of the roof ridge, the injection nozzle swings and rotates in an undulating state. Thus, compared with the case where the water discharge angle is varied, the water can be discharged to a predetermined water discharge area with a small amount of water.

  The roof watering device according to the present invention will be described in detail with reference to the accompanying drawings of FIGS. 1 to 5 showing a preferred embodiment of the present invention. FIG. 1 shows a watering device 3 for watering the roof 2 of the house 1. The watering device 3 is installed at a position away from the house 1 on the extended line side along the roof ridge portion 4 and is erected from the ground while being supported by the support member 5 in the illustrated embodiment. An injection nozzle 7 is mounted on the upper end side of the water supply pipe 6 whose lower end side is connected to the water supply source.

  The watering device 3 is provided in the middle of the water supply pipe 6 by connecting the lower end side of the water supply pipe 6 to the water pipe 8 buried underground through the main plug 8 as shown in the schematic piping diagram shown in FIG. In addition to supplying water to the injection nozzle 7 through the on-off valve 9, a drain pipe 11 provided with a drain plug 10 in a branched state with the water supply pipe 6 is provided to drain the remaining water. Uses water pipes and other common metal pipes.

  As shown in FIG. 1, it is necessary to perform the water discharge from the injection nozzle 7 to the water discharge area P from one end side P1 to the other end side P2 of the roof ridge part 4, and the injection nozzle 7 is used as means for achieving this. It is possible to change the water discharge angle α by swinging and rotating in the undulating state, but in order to save water volume, the flow rate and water pressure are controlled by varying the open / close amount by the open / close valve 9 that opens and closes the flow path. It is desirable to be able to do so.

  The on-off valve 9 can take either a manual operation or an automatic operation. When the manual operation is performed, for example, a butterfly valve is used, and the flow rate and the water pressure are varied as shown in FIG. In addition, water can be discharged to the water discharge area P from the one end side P1 to the other end side P2 of the roof ridge part 4, but in order to secure this water discharge area P, in what range the degree of opening and closing can be varied. Good thing is to make a water mark for trial and mark it.

  When performing automatic operation, an electromagnetic valve capable of program control is used as the on-off valve 9, and the electromagnetic valve is opened and closed according to a program set in advance by a control device having a timer function. It is possible to adopt a form in which a similar valve opening / closing operation is automatically performed at predetermined time intervals set in advance. When a thermal sensor is provided on the roof 2 and the temperature exceeds a set temperature, the opening / closing valve 9 It is possible to adopt a form in which automatic operation starts.

  Further, the control device described above is provided with a wireless reception function, a control signal is sent from a mobile phone terminal or the like having a transmission function to the reception unit of the control device, and an on-off valve by an electromagnetic valve is remotely operated from inside or outside the building It is also possible to adopt a form in which 9 open / close operations are performed.

  For example, the injection nozzle 7 is provided with a nut portion 12 on the base side as shown in a partially enlarged view shown in FIG. 3, and is screwed with a screw portion 13 provided on the outer peripheral surface of the upper end side of the water supply pipe 6. In addition to being able to take a form of integrally connecting, the tip side is bent at a water discharge angle α by a predetermined elevation angle so that water can be discharged from the injection port in an elevation angle state, and a water flow is applied to the inner peripheral surface of the injection port. A form in which a known spiral groove or a double spiral groove (not shown) is provided so as to be accelerated by a spiral motion may be employed.

  The water discharge angle α by the spray nozzle 7 can be set as desired according to the distance and height position of the spray nozzle 7 with respect to the roof 2, the water pressure at the time of water discharge, the length of the roof ridge portion 4, and the like. Since it is necessary to sprinkle water over the entire area of the ridge part 4, it is desirable to make the height position of the injection nozzle 7 substantially equal to that of the roof ridge part 4, and the water discharge angle α is about 45 degrees. Is set within a range of approximately 30 to 60 degrees.

  In addition, when the roof ridge 4 is long or tall like a factory, or when the water pressure is low, the same watering device 3 is placed on the opposite side of the roof ridge 4 opposite to FIG. It is possible to provide water spraying from both spray nozzles 7 at the same time or to divide the water supply pipe 6 into two high and low locations, respectively, and to provide spray nozzles 7 on the first floor roof and the second floor roof. On the other hand, it is also possible to take a form in which water is discharged and water is sprayed at the same time.

  Further, in the above-described embodiment, the water supply pipe 6 is configured by the metal pipe 6A. However, the injection nozzle 7 is provided on the upper end side of the support member 5 via the bracket 14 as shown in the partial enlarged view of FIG. A configuration in which the hose 6B made of resin or rubber, which is fixed and easy to install with respect to the injection nozzle 7, is connected via the hose stopper 15 to form the water supply pipe 6B (6) with a simpler configuration. It is also possible to take.

  In the above-described embodiment, the support member 5 is constituted by the support 5A, and the water supply pipe 6 is supported by the support 5A. However, as shown in FIG. Form in which at least three or more linear members 5B are installed and fastened between the support 16 attached to the upper side of the water supply pipe 6 made of metal pipe and the anchor 17 embedded in the ground, using the wire 5B. If a member having a necessary strength such as a tree, a fence, a masonry, or the like is in an appropriate position, these existing members can be used as the support member 5.

  When high-pressure water is discharged from the spray nozzle 7 using the watering device 3 as in the above embodiment, the water discharge falls in a distributed state from above the roof 2 onto the roof ridge 4 while drawing a parabola as shown in FIG. Later, water is sprinkled along the sloped roof 2 and flows down to the eaves (not shown). When the water is sprinkled, the roof 2 is deprived of radiant heat and cooled by vaporization heat. Can be suppressed.

  In this sprinkler 3, when a water supply pipe 6 of 1/2 liter is connected to the water pipe 9 and water is discharged to the two-story house 1, a reach distance of about 10 m is obtained at a water pressure of 4 kg / cm 2. Although it can be put into practical use without using a pump or the like in a two-story house 1 as well, for a building with a long roof ridge 4 such as a factory, two sets of watering devices 3 are used as described above. It is also possible to use the pump or use a pump to extend the reach.

  Moreover, the water discharge from the injection nozzle 7 is performed intermittently for a short time with a single water discharge amount being reduced, thereby promoting vaporization and water saving, and discharging water in an elevation angle. Because it is sprayed in a dispersed state like rain due to the influence of air resistance and breeze, it promotes the promotion of vaporization and reduces the burden on the roof structure to reduce deterioration and damage Is possible.

  In addition, an angle adjustment mechanism is provided at the connecting portion of the water supply pipe 6 and the injection nozzle 7 so that the water discharge angle can be changed according to the installation location of the watering device 3 and the wind and other environments, or the discharge form of the water discharge is, for example, a jet shape By adopting a mode in which a known switching part (not shown) is provided in the injection nozzle 7 so that switching can be made between direct current discharge and spraying diffused discharge, water discharge can be more effectively adapted to the situation. Can be done.

  In the above-described embodiment, tap water is used as a water supply source, and the sprinkled water is allowed to flow into the sewage through the dredger, but the sprinkled water and rain water can be collected from the dredger, It is also possible to adopt a form of a circulation path such as a known technique including patent documents so that other surplus water is not drained as it is, stored in a water storage tank, and pumped to the water supply pipe 6 for reuse. .

  In addition, although the above embodiment demonstrated the case where the indoor temperature rise was suppressed by sprinkling on a roof, when a neighboring house became a fire using the same sprinkler 3, it spreads fire by extinguishing a spark. It is possible to function as a device for preventing snowfall, and also to function as a device for removing snow by melting snow by discharging groundwater and hot water to snow accumulated on a roof in a heavy snowy area.

  In particular, in the case of adopting a configuration in which watering can be performed by remote control, watering can be performed to cool the room before returning home, so that it is possible to make the indoor environment comfortable when returning home and When a fire breaks out, the watering device 3 can be remotely operated in a safe area away from the fire site while evacuating immediately, extinguishing the jumping fire to the house and preventing the spread of fire.
