Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for cleaning an underdrain type waterway wall, for example.

[0002]

2. Description of the Related Art In a channel for flowing a fluid such as a water channel for cooling or irrigation or a river, a device for cleaning the inside of the channel or transporting an object is required. For example, in a power plant, a petroleum complex, a liquefied gas terminal, etc., seawater is used for various kinds of cooling, and a water channel is provided for introducing this seawater. However, a large amount of marine organisms such as shellfish, shell eggs, and algae flow into the waterways together with seawater, and there arises a problem that they adhere to and accumulate on the waterway walls.

Conventionally, the cleaning work of an underdrain type canal for removing marine organisms adhering to such a canal wall was performed manually after the canal was dried, but it is not necessary to dry the canal. As such, a moving device utilizing a water stream has been recently considered (Japanese Patent Application No. 1-293837).

[0004]

The moving device is a simple device that uses a fluid flow as a power source. However, a moving turbine is used along a fixed rope such as a rope stretched in a flow path. Since it moves, it cannot be used in the underdrain type waterway where the upper wall is also used for water.For example, when trouble occurs in the moving device itself, if it stops in the underdrain, collection and maintenance will be difficult. There is a problem such as becoming. An object of the present invention is to solve the above-mentioned problems and to obtain an apparatus which can be used safely in an underdrain type waterway or the like.

[0005]

In a moving device according to the present invention, a base body, which is installed at a fixed position with respect to a water channel and has a winch driven by a water turbine that rotates by a water flow in the water channel, and a base member in the water channel. a movable mobile, one end of the U
The drive rope wound around the inch-inch drum part and the other end fixed to the moving part, and the drum part of the winch when the rope payout length from the winch reaches a predetermined length. It has a forward and reverse mechanism for reversing.

[0006]

In the present invention, since the base and the moving part are provided separately and the moving part reciprocates by driving the rope, only the moving part of the simple mechanism needs to move in the underdrain type water channel. Even if a device trouble occurs in the waterway, the main part can be secured outside the underdrain. Further, the rope is driven by the rotational force of the water wheel of the base body. Therefore, it is possible to use the device with only fluid energy as the power source.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A moving device according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 is a schematic plan view of the moving device of this embodiment, FIG. 2 is a schematic side view, and FIG. and 4 c
It is a conceptual drive diagram of a clutch mechanism in inches .

As shown in the figure, the apparatus of this embodiment is used for cleaning an underdrain type water channel provided for introducing seawater in a power plant or the like. The base body 4 moored at the entrance open portion of the waterway 1 by the mooring line 20 has two floats 5, and the shaft 6 extending between the floats 5 is
It is rotatably supported about its axis. A water turbine 7 that is rotated by a water flow flowing in the water channel 1 is fixed so that its central axis penetrates the shaft 6.

The rotational force of the water turbine 7 due to the water flow is generated by the shaft 6
The sprocket fixed to the sprocket is rotated, and its rotational force is further transmitted by the drive chain 8 to the forward / reverse clutch box 9
Via the drum 13 to the drum 13 mounted on the base body. Therefore, in this embodiment, the shaft 6, the water turbine 7,
Drive chain 8, clutch box 9 and drum 13
To the winch 100 shown by the dotted squares in FIGS. 1 and 2.
Is constructed, and power is obtained from the water turbine 7 by this winch.
The drive rope 15 is wound and unwound.

In such a winch 100, the drive rope 15 is wound by the rotation of the drum 13, and the moving portion 16 fixed to the tip of the drive rope 15 moves upstream. The drum 13 is provided with a rope payout length detection device 12, and is connected by a clutch operation link 11 and a clutch lever 10 to a forward / reverse clutch mechanism that reverses the drum 13 when the rope is paid out by a predetermined length. .

The drive rope 15 is unwound via the rope unwinding length detecting device 12, and the rope 15 is wound up until the moving portion 16 reaches a preset upstream end, and the minimum value of the unwound rope unwinding length (setting) is set. (Value) is detected, the clutch is switched by the operation link 11 and the clutch lever 10, and the drum 13 starts reverse rotation. As a result, the rope 15 is fed downstream, and the moving portion 1 is moved by the water flow.
6 moves downstream.

The moving unit 16 has a frame 17 as a main body,
4 guard rollers 18 on each side
It is installed individually. The brush 19
Since it is attached, the waterway wall can be cleaned by the reciprocating traveling by the drive rope 15. If this embodiment is used, the underdrain type waterway wall can be easily cleaned.

The forward / reverse clutch mechanism of this embodiment will be described in detail with reference to FIGS. 3 and 4. Figure 3 and
In a winch 100 shown by a dotted frame in FIG. 4 and FIG. 4 , a driving shaft 9b and a driven shaft 9c are arranged in parallel in the clutch box 9. Sprocket 9a
Is connected by a drive chain 8 to a sprocket 9d fixed to a shaft 9b.

Gears 9e and 9h are mounted on the shaft 9b in an idle state, and a gear selecting means 8j is slidably provided between the gears 9e and 9h. On the inner side surfaces of 9e and 9h, an engaging portion for connecting with the gear selecting means 9j is provided. 9e meshes with a gear 9g fixed to a shaft 9c via a gear 9f,
9h directly meshes with a gear 9i fixed to the shaft 9c.

The gear selecting means 9j rotates with the shaft 9b and is connected to the vertically arranged arm 9k. The arm 9k is connected to the pin coupling portion 9l of the clutch lever 10 and 9m which is separated by a predetermined distance. The gear selection means 9j has a shaft 9b centered on the pin coupling portion 9l.
Move along. The shaft 9c penetrates the central axis of the drum 13, and the drum 13 also rotates as the shaft 9c rotates.

That is, when the clutch lever 10 is in the C position, the gear selecting means 9j causes the gear 9e to move by the arm 9k.
The rotational force transmitted from the water turbine 7 to the shaft 9b is transmitted to the gears 9e, 9f, 9g, and rotates the shaft 9c in the A direction. Therefore, the drum 13 also rotates in the A direction, the rope 15 is wound up, and the moving portion 16 travels in the upstream direction. When the rope 15 reaches the take-up end position, the clutch lever 10 reaches the D position, the gear selecting means 9j is switched and rotated in the B direction, the rope 15 is unreeled, and the moving portion 16 travels in the downstream direction.

[0017]

As described above, according to the present invention, the base and the moving part are separately provided, and the moving part reciprocates by driving the rope. Therefore, it is a simple mechanism to move in the underdrain type waterway. Only the moving part is required, and even if a trouble occurs in the device in the waterway, since the main part such as the driving part is located outside the underdrain, it can be used with peace of mind. Further, the rope is driven by the rotational force of the water wheel of the base body. Therefore, it is possible to use the device by using only fluid energy as a power source.
