Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to a snow melting device for roofs.
In particular, the present invention relates to a snow melting device for melting and removing snow accumulated on a longitudinally extending roof, such as an arcade in a shopping street.

(Prior art) Among the conventional devices related to such technology, the simplest one is one in which, for example, one main pipe for discharging water for snow melting is installed along the longitudinal direction at the top of the roof, and multiple streams are connected to the top of the roof. A gutter is formed on both sides of the roof by drilling an outlet or installing a large number of spray nozzles and spraying the water from there towards the snow on the top of the roof to flush the snow away. A method is used to accommodate the

In addition, in the above method, the force with which the water hits the snow on the roof head on is weak, so in order to compensate for this drawback, one main pipe installed at the top of the roof is divided into two. A conventional method has been to suspend each of them along the roof on both sides of the roof, and to melt and remove the snow accumulated on both sides of the roof by spraying water on each of them.

However, the common drawback of all of the above conventional devices is that the total length of the spray pipe is the same as the entire length of the arcade roof, and the number of spray nozzles installed increases with the length of the pipe. It is. Moreover, the longer the shopping street becomes, the longer the equipment becomes unavoidable, and the larger and more complex the equipment becomes. The resulting increase in costs was a problem.

(Purpose of the invention) This invention was made to solve the problems of the conventional device as mentioned above, and by installing a simple device, it can be used at low cost without being affected by the extended length of the roof. The object of this invention is to provide a roof snow melting device that can perform detailed snow melting work over the entire length of a roof at a low cost.

(Structure of the invention) As a means to achieve the above object, this invention is a snow melting device for a roof extended in the longitudinal direction, which runs on a pair of rails installed parallel to each other on both sides of the roof. A spray pipe is provided that spans the roof, and the spray pipe is provided with a number of spray nozzles for spraying water for snow melting toward the upper surface of the roof, and the spray pipe runs over the rail. The pump is equipped with a spray pump that runs along with the roof, and the pump sucks water accumulated by melting snow into gutters formed on both sides of the roof and sprays it from a spray nozzle on the spray pipe. It is characterized by having the following.

(Embodiment) Next, one embodiment of the roof snow melting device according to this invention will be specifically described based on the drawings.

In FIGS. 1 and 2, 1 is a gutter, which is provided along both sides of a roof 2 extending in the longitudinal direction. A spray pipe 3 is straddled along the upper surface of the roof 2, and can run along the longitudinal direction of the roof on rails 13 by means of wheels 12 provided at both ends. 11 is a wheel motor for this purpose. The spray pipe 3 is provided with a large number of spray nozzles 4 for spraying water for snow melting toward the upper surface of the roof 2.

Reference numeral 5 denotes a spray water pump, which is fixed onto the spray pipe 3 and runs along the rail 13 together with the spray pipe 3. A suction pipe 6 is fixed to the suction side of the pump 5, and its tip is immersed in water stored in the gutter 1. 16 is a main pipe, and when the pump 5 operates, the water in the gutter 1 is sent from the suction pipe 6 through the pump 5 to the main pipe 16, from which it is distributed to each spray pipe 3 and distributed to each spray nozzle. 4 to the upper surface of the roof 2. 10 is a drain valve attached to the main pipe 16.

Reference numeral 8 denotes a blower for supplying air, which communicates with the main pipe 16 via an air purge switching valve 9. pump 5
A spray water switching valve 7 is interposed between the main pipe 16 and the spray water switching valve 7, and when the blower 8 is operated with the spray water switching valve 7 closed and the air purge switching valve 9 open, the water in the spray pipe 3 is Purged. This is a necessary configuration to prevent accidents such as pipe bursting due to freezing of residual water after snow melting work in cold regions. Numeral 14 is a heating pipe for heating the water in the gutter 1, which melts the snow that has fallen into the gutter 1 from the top of the roof and makes it easier to flow. Reference numeral 15 denotes a movably stretched power cord for supplying electricity to the traveling portion.

A tape heater is wrapped around the spray pipe 3 depending on the situation. Also, rail 1
3 may have a shape for a normal vehicle, but it may also be replaced by a pipe having a rail function, which is shown in the embodiment. In this case, circulating the heating liquid through the pipe eliminates the risk of snow accumulation between the pipe and the wheels 12 freezing and interfering with smooth running.

The rail 13 must be installed horizontally, so that when the suction pipe 6 attached to the pump moves in the longitudinal direction of the roof 2, the lower end of the suction pipe is always immersed in the water in the gutter 1. It can be held.

The heating liquid to be circulated inside the heating tube 14 and inside the pipe installed with a rail function instead of the rail 13 is preferably heated hot water or antifreeze.

Although the operation of the snow melting device constructed in this way is explained in fragments in the above text,
By allowing the spray pipe 3 to run on the rail 13, it moves to a location where snow melting is required and performs snow melting work at that location one after another. in this case,
The feature of the present invention is that the water used as the material for snow melting can be pumped up from any point in the gutter 1, and in other words, the water in the gutter 1 can be used by the pump 5 regardless of the driving position. It can be said that there is one.

(Effect of the invention) Since the roof snow melting device according to this invention is constructed as described above, by simply installing the device,
The effect is that fine snow melting work can be performed over the entire length of the roof at low cost without being affected by the extended length of the roof.
