8, and a U-shaped curved groove 24 having the same radius of curvature as the door 37, and a water stop rubber 25 is attached to the curved groove 24.

In the left half of the storage chamber 20, a space with a closed cross section is formed by the body plate 26 and the lid plate 27, and this space is shaped by the movement of the door 37 when it moves up and down guided by the curved groove 24. It is said to be a space that does not have any impact.

A lid plate 2 that cooperates with the body plate 26 to form the aforementioned closed cross-sectional space.
7 holds a holding member 28 with a support plate 29 provided thereon, and a guide rod 31 is inserted through the toilet holding member 28 via an O-ring.

As shown in the fourth figure, the guide grooves 31 are provided independently on the left and right sides of the upper end of the storage chamber, and one end of each guide rod 31 in the storage chamber is connected to the upper end of the door body 17. The wires 32 are connected.

Moreover, a width bar 3 is attached to the end of each guide rod outside the storage chamber.
Wires 34 and 35 are connected to each other through wires 3 and 35, and the wires 34 and 35 join together at a point slightly apart from the width bar 33, and are connected to the wire 13.

Note that the reference numeral 30 represents a stopper, which has a function of restricting the upward movement of the guide rod 31.

The door body 17 is formed of a door 37 and a weight 36 attached to the head of the door 37, and the door 37 is connected to the storage chamber 2 described above.
It is formed of a rectangular curved flat plate having the same radius of curvature as that of the U-shaped curved groove 24 provided at the right end of the groove.

The watertight structure between the door 37 and the curved groove 24 that guides the door 37 is clearly shown in FIG. 5, which is an enlarged cross-sectional view taken along the line I--I in FIG. 3.

That is, the tip of the curved flat plate of the door 37 is placed in the curved groove 24 provided in the body plate 26 of the storage chamber 20 via the waterproof rubber 25, and this structure allows the insertion opening 38 of the door 37 to Due to this structure, the lowermost cylinder 5 is completely closed by the door 37.

FIG. 6 shows an enlarged view of the upper part of the pedestal 3. As is clear from the figure, the hoisting machine 9 is mounted on the pedestal 3, and its operation is performed by a control reducer 10. A weight 14 is suspended from the tip of a wire 26 of the hoist 9 via a hook 27.

One end of the wire 13 is connected to the head of the door 37 described above, and the other end is connected to the weight 14 via a pulley 25.

In this embodiment, the wire 13 is shown as a separate wire for connecting the door body 17 and the weight 14, and the wire 26 is shown as a separate wire for connecting the weight 14 and the sounding device 9, but this is for convenience of explanation. with a single wire 13,
Even if the door 37 is connected to one end, the hoist 9 is connected to the other end, and the weight 14 is connected in the middle, the operation and effect remain the same.

The ice making device of this invention has the above-mentioned structure and provides the following functions.

To fully close the door body 17, the hook 27 is hooked to the locking fitting 28 of the weight 14, and the control gear 9 and the control reducer 10 forming the weight lifting mechanism are hooked to the hook 27. When the bundle (not shown) of the reducer 10 is turned and the weight 14 is pulled up via the wire 26 of the hoist connected to it, this weight 14
When the other wire 13 connected to the door body 17 becomes loose, the door body 17 becomes attached to the storage chamber 20 due to the weight 36 attached to the head of the door 37.
The door 37 descends while sliding in the curvature groove 24, and is fully closed when the outer edge of the door 37 descends to the extent that it covers the entire opening of the lowermost cylinder 5.

That is, the water inside the cylinder gate 1 is stopped by the door body 17, and its watertightness is ensured by the water stop rubber 25 provided between the door 37 and the curved groove 24.

The closing operation is normally performed by a preliminary gate provided in the water pipe 2)-1.
5 (Cut off the water conduit (marked with a +) on the downstream side of the water conduit, and carry out with water present in the cylinder gate and the water conduit 2.

As mentioned above, after fully opening the door body 17, the preliminary gate 15
Open the water pipe and empty the water inside the water pipe, then repair the water pipe.

As mentioned above, the lifting mechanism lifts the weight 14 to fully open the door body 17, but at this time, the lifting weight 1
4 is the door body 1 because the hoisting machine 9 is self-locked by the control reducer 10 so that the wire 13 cannot be loosened.
7 is never opened.

To open the door body 17; When the door body 17 is in the closed state, that is, after repairing the water pipe, etc., the hook 27 of the wire 26 must be
4, the door body 17 is lowered by the weight of the weight 14 connected via the wire 13, and the door 37 rises while sliding in the curvature groove 24 of the storage chamber 20. The lower cylinder 5 is unblocked and fully opened.

Note that when the entire cylinder gate 1 is pulled up, that is, when the lowermost cynonda 5 is raised by the hoisting machine 7 via the wire 11, the door body 17 provided on the lowermost cynonda 5 is also raised along with this lifting. Even in this state, the door body 17
Since the cylinder gate 1 is maintained in the open state by the weight 14 via the wire 13 in accordance with the rise of the cylinder gate 1, the door body will not be in the closed state.

(In this case, the weight 14 and the wire 26 are separated.) This invention produces the above-mentioned structure and operation, and has the following effects.

The door body 17 is always kept fully open by tensioning the wire 13 connecting it by the weight of the weight 14, and when fully opened, the control gear 9 is rotated by rotating the bundle of the control reducer 10. Water can be utilized with a simple structure of lifting the weight 14 via the wire 26 and loosening the other wire 13 connected to it.

In addition, installation is easy because there is no need to cut out the dam and provide an ice-making chamber, unlike conventional systems in which water use gates are provided in water pipes.

In particular, this invention forms a water control device by providing the water control part 4 in the bottom cylinder 5 integrally with it. Since there is no need to attach or remove it each time it is used, water can be quickly and easily controlled.

Furthermore, the watertightness between the door 37 and the curved groove 24 is achieved only by surface contact between the two via the water stopper rubber 25, so the watertightness increases as the water pressure increases. It is.

Another embodiment of the invention will be described below with reference to FIGS. 7 and 8.

FIG. 7 is an enlarged cross-sectional view showing the state of sliding contact between the door 37 and the curvature groove 24, and FIG. 8 is an enlarged cross-sectional view taken along the line III-III in FIG. 7. , door 37
This embodiment differs from the previous embodiment in that a roll 38 is provided on the side edge of the embodiment.

The roll 38 has a shaft 39 at a position in sliding contact with the curvature groove 24.
Because of the spring 40 which is pivotally supported by and presses the shaft 39, the door 37 is held in a state separated from the water stop rubber attached to the curvature groove 24 when water is not stopped.

In the case of this other embodiment, the door body 17 is moved through the curvature groove 24 by the rotation of the roll 38, so that the door body 17 can easily enter.

(See the chain diagram) When water is used, water in the water pipe is pushed out to create a pressure difference between the upper and lower surfaces of the door 37, and the door 37 is crimped against the water-stop rubber 25 to ensure watertightness.
