[0006]

[Action]

 With the above configuration, during installation work, when the space inside the weight of the stopper device is filled with air, the moving pedestal to which the installation object such as the submersible pump is fixed is placed on the rail at a shallow water depth. Place. At this time, the stopper device swings upward due to the buoyancy of the weight portion, and the stopper portion is in a state of being separated from one side of the rail.

Then, after placing the movable pedestal on one side surface of the rail, the air in the internal space of the weight section is exhausted by the air supply / exhaust means. Along with this exhaust operation, external water flows into the inner space of the weight section through the inlet / outlet means, the weight section loses buoyancy and sinks due to its own weight, and the stopper section swings together with the weight section and the arm section. Engage one side of the rail. In this state, the stopper portions of the left and right stopper devices hold one side of the corresponding rail, and the weight portion keeps the stopper portions in the engaged state by the weight thereof. Then, while sliding the moving pedestal on the rail, the moving pedestal is moved toward a deep water position and installed at a predetermined position.

At the time of removing work, after moving the pedestal to a position where the water depth is shallow while sliding on the rail, air is supplied to the internal space of the weight portion by the air supply / exhaust means. Along with this air supply operation, the water in the internal space of the weight portion flows out through the inlet / outlet means, and the weight portion floats by buoyancy. Therefore, the stopper portion swings together with the weight portion and the arm portion and is separated from one side of the rail, and the engaged state of the stopper portion with respect to one side of the rail is released. In this state, move the pedestal off the rail.

Therefore, the attaching / detaching operation of the stopper device can be performed at a shallow depth of the water, and the attaching / detaching operation only needs to supply / exhaust the weight portion, which makes the underwater work unnecessary and improves workability.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the pair of left and right rails 1 are laid under the surface of a water such as a pond from the shallow shore side to the deep pond bottom side and have an L-shaped cross section. It has a backing plate 2 at the bottom of the pond. A moving pedestal 3 is placed on the rail 1, and the moving pedestal 3 slides on one side 1a of the rail 1 via a sliding member 4, and can be joined to and separated from the rail 1. A horizontal submersible pump, which is an object W to be installed in water, is fixed to the moving base 3.

A pair of left and right stopper devices 5 are swingably provided via hinges 6 on both sides of the moving base 3 in the rail direction of the rail 1. The stopper device 5 includes a stopper portion 7 and a weight portion 9 fixed to the stopper portion 7 via an arm portion 8. The stopper portion 7 has a U-shaped cross section so as to embrace one side 1a of the rail 1 and swings between a position where it engages with the side 1a and a position where it disengages. The weight portion 9 has a hollow body, and an inlet / outlet port 10 is open at the lower end portion. At the upper end of the weight 9, there is provided a tube-shaped air supply / exhaust pipe 11 communicating with the internal space for air supply / exhaust, an exhaust valve 12, and a compressor or air pump 14 having a stop valve.

The operation of the above configuration will be described below. During the installation work of the object W, the object W such as an underwater pump is fixed to the moving pedestal 3 in advance, and the moving pedestal 3 is placed on the rail 1 at a position where the water depth is shallow. At this time, the internal space of the weight portion 9 of the stopper device 5 is filled with air in advance. Therefore, the stopper device 5 is swung upward by the buoyancy of the weight portion 9, and the stopper portion 7 is in a state of being separated from the one side 1a of the rail 1.

Then, when the exhaust valve 12 is opened after the movable pedestal 3 is placed on the side 1a of the rail 1, the internal air of the weight 9 is mixed with water from the inlet / outlet port 9 by the exhaust valve 12. Since the weight portion 9 loses buoyancy and sinks due to its own weight as it is discharged, the stopper portion 7 swings together with the weight portion 9 and the arm portion 8 on the hinge 4 to engage with one side 1a of the rail 1.

In this state, the stopper portions 7 of the left and right stopper devices 5 hold one side 1a of the corresponding rail 1, and the weight portion 9 keeps the stopper portion 7 in the engaged state by its weight. Then, the tow cable 15 connected to the object W or the movable pedestal 3 is unwound, and the movable pedestal 3 is slid on the rail 1 and moved toward a deep water position to a predetermined position where it abuts on the backing plate 2. Install.

At the time of removal work, after moving the pedestal 3 to a position where the water depth is shallow while sliding it on the rail 1, the exhaust valve 12 is closed and the air pump 14 is driven to supply / exhaust air to / from the weight portion 9. Air is supplied through tube 11. Along with this air supply operation, the water in the internal space of the weight portion 9 flows out through the inlet / outlet port 10, and the weight portion 9 floats by buoyancy. Therefore, the stopper portion 7 swings together with the weight portion 9 and the arm portion 8 and is separated from the side 1a of the rail 1, and the engagement state of the stopper portion 7 with the side 1a of the rail 1 is released. In this state, the moving base 3 is detached from the rail 1.

FIG. 3 shows another embodiment of the present invention, in which the upper surface of the weight portion 9 is opened as an inlet / outlet means to form an opening 21 and the movable top plate 22 is made watertight in the weight portion 9. Some are dressed. A collar portion 23 is provided around the opening of the weight portion 9 to prevent the movable top plate 22 from slipping out.

According to this configuration, when air is supplied through the air supply / exhaust pipe 11 during air supply, the supplied air drains the water in the internal space to the outside through the opening 21 via the movable top plate 22, and the weight portion 9 buoyancy increases. When air is exhausted through the supply / exhaust pipe 11 during exhaust, water pressure presses the movable top plate 22, external water flows into the internal space through the opening 21, and the weight portion 9 loses buoyancy. Other functions and effects are similar to those of the previous embodiment.

FIG. 4 shows still another embodiment of the present invention, in which the film body 31 is provided in the weight portion 9. According to this configuration, when air is supplied through the air supply / exhaust pipe 11 during air supply, the film body 31 swells to form the air layer 32, and the water in the inner space is drained to the outside through the opening 21 as the air layer 32 expands. However, the buoyancy of the weight portion 9 increases. When air is exhausted through the air supply / exhaust pipe 11 at the time of exhaust, the film body 31 shrinks due to water pressure and the air layer 32 contracts, external water flows into the internal space through the opening 21, and the weight portion 9 loses buoyancy. Other functions and effects are similar to those of the previous embodiment.
