Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for carrying a spiral pipe installed in a reservoir pond in order to collect thermal energy of a so-called reservoir such as a pond, lake, dam lake or reservoir.
[0002]
[Prior art]
The present inventors have so far developed a heat supply system that uses a geothermal heat utilization system based on a pile heat exchange system, and has introduced it into building air conditioning and hot water supply facilities and road snow melting.
[0003]
In recent years, focusing on the fact that there are many so-called reservoirs such as ponds and reservoirs for securing agricultural water in rural areas and mountain villages, the heat in the pound using the thermal energy in the reservoirs We are developing a heat supply system using an exchange system.
[0004]
This heat supply system can also be used for building air conditioning and road melting. For example, when used for air conditioning of a building, as shown in FIG. 5, a polyethylene spiral pipe P installed mainly at the bottom of the reservoir L, and a heat pump T connected to the pipe P and installed in the building. And consist of And in the winter season, the antifreeze is circulated through the spiral pipe P at the bottom of the reservoir pond L to absorb the heat energy in the reservoir pond L as a heat source of the heat pump T, and hot water or hot air is supplied indoors from the heat pump T Heat the building and supply hot water. In summer, exhaust heat generated by cooling the room by the heat pump T is released into the reservoir L by the antifreeze circulating through the spiral pipe P, thereby cooling.
[0005]
Further, in order to use this heat supply system for melting snow on a road, as shown in FIG. 1, a heat pipe H is buried in the ground surface portion of the road R, and a spiral pipe P disposed in the heat pipe H and the reservoir L The antifreeze is circulated by a circulation pump, and the heat collected in the reservoir L is released by the heat radiating pipe H to melt the snow on the road surface.
[0006]
[Problems to be solved by the invention]
In order to deploy this heat supply system, it is necessary to arrange the spiral pipe P at the bottom of the reservoir L. However, it is very cumbersome to do this manually. Normally, the spiral pipe P has a diameter of about 20 mm and a total length of 100 m, so it cannot be lifted manually. In order to construct one system, it is necessary to use a large number of spiral pipes P. It is impossible to manually carry all the spiral pipes P to the bottom of the reservoir L.
[0007]
Moreover, although it can also consider performing using a crane apparatus, since the distance from the road R to the reservoir L is often long, it is also difficult.
[0008]
The present invention was devised in view of these problems, and provides an apparatus that can easily carry a spiral pipe used in a heat supply system by a heat exchange system in the pond using heat energy in the reservoir into the reservoir. The task is to do.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of a spiral pipe carry-in device 1 according to the present invention. This is a device for carrying a spiral pipe P into the reservoir pond L in order to collect the thermal energy of the reservoir pond L in order to melt the snow on the road R. It is comprised with the trolley | bogie 30 and the latching mechanism 40. FIG.
[0011]
The gantry 10 is provided with vertical pipes 11 standing at substantially equal intervals along the descending inclined surface S from the road R to the reservoir L in front of the road R. The vertical pipes 11 are linearly inclined to the left and right vertical pipes 11. The inclined pipe 12 is fixed, and further, the horizontal pipe 13 is laid between the inclined pipes 12 on the left and right sides at substantially equal intervals.
[0012]
The fixed carriage 20 is fixed on the gantry 10 and is configured by rotatably providing a plurality of wheels (rubber wheels) 21 at regular intervals on both end portions thereof. The fixed carriage 20 is composed of a plurality of small carriages 20a, which can be connected to each other at the installation site by bolts, welding, or the like.
[0013]
The movable carriage 30 is configured by providing a plurality of divided carriages 30a in series on the fixed carriage 20 and connecting them with welding or bolts. In this movable carriage 30, a spiral pipe P is placed on the upper surface of the flat main body 31. In addition, an inverted concave guide rail 32 that receives the rubber wheel 21 of the fixed carriage 20 is fixed to both side ends of the main body 31, and the rubber wheel 21 is rotated by its own weight toward the front reservoir L. It moves downward.
[0014]
Further, the latching mechanism 40 is attached to the fixed carriage 20 and latches on the front end of the movable carriage 30 to temporarily prevent the movable carriage 30 from moving downward. The structure of the latch mechanism 40 is not limited. For example, using a cylinder, the rod can be extended to hook the moving carriage 30 and contracted to release the hook. In addition, the movable carriage 30 is latched at the upper end of the bar, and the lower end thereof is pivotally fixed to the fixed carriage 20, and the movable carriage 30 is latched by rotating about the pivotal portion. And the cancellation thereof.
[0015]
The operation of the spiral pipe carry-in device 1 will be described. First, the gantry 10 and the fixed carriage 20 in the carry-in device 1 are provided on the descending slope S from the road R to the reservoir L, and the movable carriage 30 is placed on the fixed carriage 20. At this time, for example, the front end portion of the movable carriage 30 is latched by the latch mechanism 40 so as not to move forward. In this state, the spiral pipe P is placed in order from the front end of the movable carriage main body 31 using a crane device or the like. The spiral pipe P is transported to the road R of the place on a truck or the like.
[0016]
After the spiral pipe P is placed on the moving carriage 30, the latching mechanism 40 is unlocked. As a result, the moving carriage 30 moves forward on the descending inclined surface S by its own weight and reaches the reservoir pond L. At this time, since the moving carriage 30 is provided with the guide rail 32 that receives the rubber wheel 21 of the fixed carriage 20, the moving carriage 30 moves forward smoothly and linearly without meandering.
[0017]
The moving carriage 30 that has landed on the reservoir pond S sinks in the shallows of the reservoir pond L due to its own weight, and conversely, the spiral pipe P floats on the water because air exists in the pipe. Accordingly, the spiral pipe P can be automatically lowered from the moving carriage 30. In order to prevent water from entering the spiral pipe P, both end openings of the spiral pipe P can be closed with stoppers.
[0018]
Further, the rubber wheel 21 that is easily damaged is provided on the fixed carriage 20 and is not provided on the movable carriage 30, so that the movable carriage 30 may be damaged by an impact when entering the reservoir L, or the reservoir pond. It is possible to avoid a situation in which deterioration is accelerated due to the influence of L water.
[0019]
The moving carriage 30 sunk in the shallows is collected with a winch or the like, placed on the stationary carriage 20 again, and used to carry in a new spiral pipe P. Further, the spiral pipe P floating on the water is pulled to a target place with a boat or the like, and is then submerged in the bottom of the reservoir pond L. In this way, after a plurality of spiral pipes P are sunk in a target place, they are connected to a heat radiating pipe H provided on the road R via a connecting pipe or the like, and used as a system for collecting thermal energy in a heat supply system. .
[0020]
【The invention's effect】
Since the spiral pipe carrying device 1 according to the present invention carries the spiral pipe P into the reservoir L by the moving carriage 30 placed on the gantry 10 and the fixed carriage 20, the work is easy. In addition, even when the distance from the road R to the reservoir L is long and a crane device or the like cannot be used, it can be easily carried in.
[0021]
Furthermore, since the spiral pipe P is floated on the water of the reservoir L and the moving carriage 30 is submerged by its own weight, the spiral pipe P is automatically lowered from the moving carriage 30, so that the carrying-in work is easy. .
[0022]
Moreover, since the fixed carriage 20 is provided with wheels 21 and the movable carriage 30 is provided with guide rails 32 for receiving the wheels 21, the movable carriage 30 can be reliably landed on the reservoir pond L without meandering. The easily damaged wheel 21 (especially in the case of a rubber car) can be protected from water and impact. Therefore, it is excellent in durability.
