本発明は、管等の通路によりごみを真空吸引するシステ
ムや有形物を圧送するシステム等において、通路の閉塞
物を圧力水で崩して閉塞を解除するようにした閉塞解除
装置に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention is used in systems that vacuum vacuum suction of waste through passages such as pipes, systems that pump tangible objects, etc., by breaking up obstructions in passages with pressure water. The present invention relates to a blockage release device for releasing the blockage.
（従来の技術）
従来より、一定の場所に溜められたごみを旨を経て真空
吸引することにより、ごみ回収車に回収するようにした
ごみ回収システムにおいては、管の一部がごみにより閉
塞した場合、ごみの回収が続行できなくなることから、
この管を閉塞した閉塞物（ごみ）を圧力水により崩して
閉塞を除去するようにした閉塞除去装置が具備されてい
る。(Conventional technology) Conventionally, in garbage collection systems in which garbage accumulated in a certain place is collected by vacuum suction through a vacuum suction and collected by a garbage collection truck, there is a problem in which part of the pipe is blocked by garbage. If this happens, garbage collection will not be able to continue.
A blockage removal device is provided that uses pressure water to break up the blockage (dust) that has blocked the pipe and removes the blockage.
この閉塞除去装置は、可撓性を有する長尺ホースの先端
に噴射ノズルを接続したものであり、噴射ノズルには、
前端に閉塞物を崩す噴射孔が開口するのみならず、斜め
後方に向かって開口する推進用噴射孔が形成されており
、ノズルを管内に挿入したとき、その推進用噴射孔から
斜め後方に向かって噴射される圧力水の噴射力によりノ
ズルを前進させ、ノズルが閉塞位置に達すると、前端の
噴射孔から噴射される圧力水で閉塞物を崩すようになさ
れている。This blockage removal device has an injection nozzle connected to the tip of a flexible long hose, and the injection nozzle includes:
In addition to the injection hole opening at the front end to break up obstructions, there is also a propulsion injection hole that opens diagonally backwards, and when the nozzle is inserted into the pipe, the propulsion injection hole opens diagonally backwards. The nozzle is moved forward by the jetting force of the pressurized water jetted from the nozzle, and when the nozzle reaches a closed position, the clogged object is broken down by the pressurized water jetted from the injection hole at the front end.
（発明が解決しようとする課題）
この従来のものでは、ノズル及びホースを挿入する管が
ストレート形状であると、ノズルは管内を比較的深くま
で前進する。ところが、管が曲がっていて、その曲率半
径が小さい場合には、例えばホースが管のコーナ部に接
触して抵抗となり、ノズルの推進力だけでは前進し難く
なる。(Problems to be Solved by the Invention) In this conventional device, if the tube into which the nozzle and hose are inserted has a straight shape, the nozzle advances relatively deep inside the tube. However, if the pipe is curved and its radius of curvature is small, for example, the hose will come into contact with the corner of the pipe and create resistance, making it difficult to move forward using only the propulsive force of the nozzle.
また、管がストレート形状であっても、ホースが長くな
ると、その先端ノズルに至るまでの管路抵抗の増大によ
りノズルから噴射される圧力水の噴射力や噴射量が不足
し、ノズルの推進力が低下して前進が停止する。In addition, even if the pipe is straight, if the hose becomes long, the pressure water ejected from the nozzle will be insufficient in jet force and amount due to the increase in pipe resistance up to the nozzle at the end, resulting in the nozzle's propulsive force. decreases and forward movement stops.
こうした管路抵抗の増大を補償するためには、水圧を上
げるとよいが、ホースの耐圧を上げるべくその構造を丈
夫にする必要があり、重量が増大するので、前進抵抗が
大きくなる。しかも、ホースの硬度も増大するので、曲
げ固さが大きくなって曲がり難くなり、やはり前進力に
限度がある。In order to compensate for this increase in pipe resistance, it is good to increase the water pressure, but in order to increase the pressure resistance of the hose, it is necessary to make the structure of the hose more durable, which increases the weight and increases the forward resistance. Moreover, since the hardness of the hose also increases, its bending stiffness increases, making it difficult to bend, and there is still a limit to its forward force.
本発明は斯かる諸点に鑑みてなされたもので、その目的
は、ホース等の給水管の途中に推進手段を設けることに
より、先端のノズルまでの長さが長くても、全体の推進
力を大に確保し、よって先端ノズルを管等の通路に奥深
くまでスムーズに進入させてその閉塞物を確実に解除で
きるようにすることにある。The present invention has been made in view of these points, and its purpose is to provide a propulsion means in the middle of a water supply pipe such as a hose, thereby increasing the overall propulsive force even if the length to the nozzle at the tip is long. The purpose is to secure a large amount of space so that the tip nozzle can smoothly enter deep into a passage such as a pipe and reliably release the blockage.

後端の中間給水管の後端を圧力水供給源に接続する構成
とする。The intermediate water supply pipes are alternately connected to the intermediate nozzles so that the inner diameter increases toward the rear side, and the rear end of the rearmost intermediate water supply pipe is connected to a pressure water supply source.
また、請求項（２）に係る発明では、上記の構成におい

よる推進力によりノズルが給水管を引っ張りながら前進
する。(Function) With the above configuration, in the invention according to claim (1), when unblocking the passage, first, the tip water supply pipe with the tip nozzle connected to the front end is inserted into the passage; Pressure water is supplied from the rear end. This pressurized water is injected from the injection hole at the front end of the tip nozzle, and also from the propulsion injection hole toward the rear, and the nozzle moves forward while pulling the water supply pipe due to the propulsive force of the pressure water from this propulsion injection hole. do.
この前進により先端給水管が後端近くまで通路内に進入
すると、圧力水の供給を一旦停止し、給水管の後端に中
間ノズルを介して中間給水管の前端を接続し、上記中間
ノズルを通路に入れながら、圧力水の供給を再開する。When the tip water supply pipe enters the passage near the rear end due to this forward movement, the supply of pressurized water is temporarily stopped, and the front end of the intermediate water supply pipe is connected to the rear end of the water supply pipe via an intermediate nozzle. Restart the pressure water supply while filling the passage.
これにより中間ノズルの推進用噴射孔から圧力水が噴射

管を引っ張りかつ前側の先端給水管を後方から押しなが
ら通路内を前進する。勿論、このとき、先端給水管は先
端ノズルからの後方噴射による推進力によっても引っ張
られる。As a result, pressurized water is injected from the propulsion injection hole of the intermediate nozzle, and the intermediate nozzle moves forward in the passage while pulling the intermediate water supply pipe behind it and pushing the tip water supply pipe on the front side from behind. Of course, at this time, the tip water supply pipe is also pulled by the propulsive force generated by the rear jet from the tip nozzle.
中間給水管が後端近くまで通路内に進入すると、圧力水

同士を中間ノズルを介して接続しながら前進させること
で、閉塞解除装置全体の長さが次第に長くなる。When the intermediate water supply pipe enters the passage near the rear end, the supply of pressure water is stopped, and the front end of the second intermediate water supply pipe is connected to the rear end of the intermediate water supply pipe via the second intermediate nozzle, and the Restart the pressure water supply while placing the intermediate nozzle in the passage. Then, pressurized water is injected from the propulsion injection hole of the intermediate nozzle, and the intermediate nozzle moves forward in the passage together with the intermediate water supply pipes before and after the intermediate nozzle due to the propulsion force. Similarly, the intermediate water supply pipes are moved forward while being connected to each other via the intermediate nozzle, thereby gradually increasing the length of the entire blockage release device.
そして、前端の先端ノズルが閉塞物に達すると、その前
方への噴射孔から噴射される圧力水により閉塞物が崩さ
れ、このことにより通路の閉塞が解除される。When the tip nozzle at the front end reaches the blockage, the blockage is broken by the pressure water jetted forward from the injection hole, thereby unblocking the passage.

進用噴射孔からの圧力水により推進力が与えられるので

前進して閉塞位置に達する。Therefore, in this case, the deocclusion device is given propulsive force by pressure water from not only the tip nozzle at the front end but also the propulsion injection hole of the intermediate nozzle placed in the middle, so the passage is long or the passage is not curved. Even if it is tight, it moves forward smoothly and reaches the closed position.
また、中間給水管の内径は先端給水管よりも大きく、し

略等しくでき、各々に同程度の推進力を確保できる。In addition, the inner diameter of the intermediate water supply pipe is larger than the tip water supply pipe, and each intermediate water supply pipe is larger at the rear, so when looking at the entire device, the inner diameter of the water supply pipe on the rear side is larger than that on the front side. . For this reason, the pressure water pipe resistance is small in the water supply pipes close to the pressure water supply side, and the pipe resistance increases as you move toward the front side. The pressure of the pressurized water injected from the nozzles can be made approximately equal, and the same level of propulsive force can be secured for each.
請求項（２）に係る発明では、ノズルにおける圧力水の
噴射孔の総断面積が後側のノズルはど前側のものよりも
大きいので、前側のノズルから噴射される圧力水の水圧
を後側ノズルと略等しくして、各ノズルの推進力をさら
に均等にすることができる。In the invention according to claim (2), since the total cross-sectional area of the pressurized water injection holes in the nozzle is larger than that of the nozzle on the rear side, the pressure of the pressurized water injected from the nozzle on the front side is applied to the rear side. It is possible to make the propulsive force of each nozzle more even by making it substantially equal to the nozzle.
