Description

[Detailed Description of the Invention] This invention relates to a sprinkler-type snow melting device that melts accumulated snow on the upper surface of a sloped roof by spraying warm water onto the snow.

Figure 3 shows a conventional sprinkler-type snow melting device, with gutter 1,
There is a semicircular roof 2 above the roof 1, and a water sprinkler pipe 3 is fixedly installed above the center of the roof 2. A large number of nozzles 4, 4... are provided on both sides of the sprinkler pipe 3 along the length of the sprinkler pipe 3, and the hot water pumped into the sprinkler pipe 3 is directed from the nozzles 4, 4... to the snow on the roof 2. Water is sprayed on the ground. The hot water used in this case is usually underground water, which melts the snow on the roof first from the point 5, 5, etc. directly below where the water falls, and then melts the snow on the roof. Points 6, 6, etc. of the Tsuzu sewage channel will melt, but remaining snow 8, 9 will remain between the nozzles and near the eaves 7, respectively, or the sewage will freeze. It is difficult to expect results from the snow melting, such as the formation of icicles 10 on the eaves 7. In addition, in some cases, the hot water that is being sprayed sinks under the remaining snow 9 and flows down, so that the remaining snow 9 is released from the top surface of the roof 2 like a leg being scooped out, and remains in the form of snow or ice all at once. Snow may sometimes fall into the gutter 1, and this condition is called the worst condition for performing snow removal work, making it difficult to deal with the snow in the gutter 1 later.

This idea was made to solve the above-mentioned problems with the conventional equipment, where some of the snow on the roof is left as residual snow or falls into the gutter while still frozen. It is possible to melt all of the snow in an orderly manner, and by adjusting the amount of water sprinkled according to the amount of snow, it is possible to perform complete snow melting operations using an efficient amount of water. The object of the present invention is to realize a device that can perform this work with high efficiency.

As a means to achieve the above object, the present device has a sprinkler pipe installed in the air at an appropriate distance from the sloping roof and approximately parallel to the eaves of the roof. A large number of nozzles are provided along the length of the water sprinkling pipe for discharging hot water to areas near the water pipe, and means for repeatedly rotating the water pipe within a certain angle, and the speed of the rotational motion can be set arbitrarily. Adjustable means is attached, and the setting of the constant angle of the repetitive rotational movement is such that the width of the water discharged from the nozzle gradually moves upward from the part near the eaves of the sloping roof according to the rotation of the water pipe, and reaches the ridge of the roof. It has a range of angles and configurations.

Next, the configuration of the present device will be explained in more detail with reference to examples. 1 and 2 show an embodiment of the present device, in which there is a semicircular roof 2 above the left and right gutters 1,1. Reference numeral 11 denotes a water sprinkler pipe, which is installed in the air at an appropriate distance from the roof 2, almost parallel to the eaves 7 of the roof 2. In the illustrated example, one water pipe 11, 11 is installed on each side. Each sprinkler pipe 11 is provided with a large number of nozzles 12, 12, . . . along the length of the sprinkler pipe 11 for spraying hot water to a portion A of the roof 2 near the eaves 7. 13 is a worm wheel 13 fixed to the water pipe 11; 14 is a worm that engages with the worm wheel 13; 15
are reversible motors for rotationally driving the worm 14, and these motors are combined with each other to function as a means for giving repeated rotational motion within a certain angle to the water spray pipe 11. 16 is a regulator for adjusting the rotational speed of the reversible motor 15, and 17 is a switch button for starting/stopping the reversible motor 15 and switching the rotation direction.

Setting the constant angle in the repeated rotational movement within a certain angle given to the water sprinkler pipe 11 is as shown in FIG. Move to
The angle is set within a range until finally reaching the ridge 18 of the roof. Further, the rotation of the sprinkler pipe 11 for snow melting operation is always positioned to start from part A, that is, from the lowest part of the roof.

To explain the snow melting operation and its effects by the present device, hot water is sprayed from the nozzle 12 to the area A by sending water to the water sprinkling pipe 11, and at the same time, by pressing the switch button 17, the water sprinkling pipe 1
1 gives the upward rotation of the drainage area. Further, the rotational speed of the water sprinkler pipe 11 is adjusted by the regulator 16 so that the rotational speed becomes the required rotational speed according to the amount of snowfall. As a result, when the snow melting in part A ends, the water discharge area can move to part B and in the same way to part C, so there is no wasteful water discharge in the meantime, and the snow melting area This also eliminates the problem of moving to the next area while the area remains incomplete. This prevents frozen snow on the roof or icicles that have formed on the eaves from falling into the gutter, allowing the efficiency of snow melting operations to be maintained at the highest level possible depending on the amount of snow. effective.
