[Conventional technology]

Conventionally, this type of apparatus is a combination of the apparatus shown in Japanese Utility Model Publication No. 62-111622 and the apparatus shown in Japanese Utility Model Publication No. 63-021677, as shown in the section of the prior art of Japanese Patent Application Laid-Open No. 1-299170. ,
A device for switching the payout length of the cable for suspending the ocean sensor in response to electric signals was realized.

FIG. 4 is a perspective view of a main part showing a conventional example, and FIG. 5 is a side sectional view showing an ocean sensor equipped with the same conventional example.

First, in FIG. 5, reference numeral 1 is a floating portion having buoyancy, 2 is a cable pack portion in which cables for suspension are stored, 3
Is a cylindrical case for accommodating each of these mechanisms, which is the main body of the ocean sensor, and the switching lever actuating mechanism of the present invention is installed between the floating part 1 and the cable pack part 2.

The configuration of the switching lever actuating mechanism will be described below by taking as an example the one in which the cable length is switched in three stages.

In FIG. 4, 6a and 6b are switching strings, one end of which is locked at a predetermined feeding position of the air-cord cable 7, and 8a and 8b are one end of which is fixed on the pressing plate 9 and the other end of which is fixed. A wire-like spring holding the ends of the switching strings 6a, 6b penetratingly held therein, and 10 is a switching lever whose tip is rotationally moved to the wire-like springs 8a, 8b side.
The a and 8b and the switching lever 10 constitute a fixing means for fixing the switching strings 6a and 6b.

The fixing means has no fixing action unless it operates.

11 is a shaft for rotating the switching lever 10,
The switching lever 10 and the shaft 11 are fitted so as to be detachable in the expansion direction, and can be separated during expansion.

The switching string 6a is locked at a position shorter than the locking position of the switching string 6b, and when the air-core wound cable 7 is sequentially fed out from the inside, the part of the switching string 6a is first. However, there is a positional relationship in which the portion of the switching string 6b is next extended.

Reference numeral 12 denotes a rotating device connected to the shaft 11, and the rotating device 12 rotates right and left in response to an electric signal. Also,
The switching lever 10 and the shaft 11 are fitted so as to be detachable in the expanding direction so that they can be separated when expanding.

Next, the operation will be described with reference to FIGS. 6 (a) and 6 (b).

Before the marine sensor starts spreading, it is installed in the floating portion in the state shown in FIG. 6 (a), and the shaft 11 rotates and fits in response to the electric signal sent from the control unit (not shown). Rotate the switching lever 10. After the operation of the switching lever 10 is completed, the ocean sensor extends the cable 7 while unrolling the cable 7. The cable 7 is a switching string 6a or
The feeding is stopped by the switching string 6b, the feeding is continued until it is fixed, and finally the stretching is performed as shown in FIG. 6 (b), and the sensor unit 3 is suspended to the depth L.

The cable length is switched as follows.

If the rotating device 12 does not rotate, that is, the switching lever
When 10 does not rotate, the switching strings 6a and 6b are disengaged from the wire springs 8a and 8b, all the cables 7 are paid out, and the sensor unit 3 is suspended to the deepest depth L.

When the rotating device 12 rotates, for example, in the counterclockwise direction, the switching lever 10 also rotates in the counterclockwise direction, hits the wire-like spring 8a, locks the switching string 6a, and stops the feeding of the cable 7 at this position. 3 is suspended at the shallowest depth L.

When the rotating device 12 rotates in the clockwise direction in the opposite direction, the switching lever 10 also rotates in the clockwise direction, hits the wire-like spring 8b, locks the switching string 6b, and the feeding of the cable 7 is stopped at this position. Is hung at an intermediate depth L.

[Problems to be solved by the invention]

However, according to the conventional technology with the above configuration, if the distance between the rotating device and the switching lever increases, the shaft becomes longer and the rigidity of the shaft decreases, so a bearing must be provided in the middle of the large marine vessel. When used as a sensor, there is a problem that the structure and assembly become complicated.

Further, if the shaft becomes long and the torsional rigidity of the shaft decreases, it becomes impossible to reliably rotate the switching lever to the correct position, and there is a problem that the operation reliability becomes low.

Furthermore, when assembling the floating part and the cable pack part in a stack, it is necessary to accurately fit the position of the floating part and the cable pack part because the shaft needs to be accurately fitted to the switching lever, which makes assembly difficult. There was a problem.

In view of the above problems, the present invention has a structure that reliably transmits a rotational force from a rotating device of a floating portion to a switching lever of a cable pack portion with high rigidity, and maintains a high operating reliability and a floating portion and a cable pack portion. It is an object of the present invention to provide a switching lever actuating mechanism capable of accommodating a large intermediate structure between them.

The present invention also provides a switching lever actuating mechanism capable of accommodating a large intermediate structure between the floating part and the cable pack part by obtaining a structure that can effectively use the space between the floating part and the cable pack part. To aim.

Further, another object of the present invention is to obtain a structure which can be assembled only by loosely aligning the position and improve the work efficiency of the assembly.

[Means for Solving the Problems]

To achieve the above object, the present invention rotates the vertical rotary motion transmission means to actuate the switching lever.

Further, the vertical rotary motion transmitting means is installed on the circumferential side of the rotating device.

Further, the present invention enables the connection between the levers to be achieved by a loose and accurate fitting.

That is, the present invention rotates the rotating device mounted on the floating portion according to a command from the control unit, transmits the rotational force to the cable length switching lever mounted on the cable pack unit, rotates the same, and switches the switching lever. In the switching lever actuating mechanism of the cable length switching device for selectively fixing the locking portion of the predetermined cable length to the case side to adjust the cable length, the rotary motion of the rotating device is divided into horizontal arcs. A horizontal rotary lever that converts into motion and a central part are rotatably locked, and the upper end is slidably fitted to the tip circular arc motion part of the horizontal rotary lever, and the lower end is slidable on the switching lever and falls off. It has a vertical rotation lever that is fitted so that it can rotate through the horizontal rotation lever and the vertical rotation lever. Characterized by the transmitting rotary motion to the switch lever.

[Action]

With the above configuration, according to the present invention, the control unit rotates the rotating device in a predetermined direction when the cable length is switched when the ocean sensor is used.

Then, the rotary motion of the rotating device is converted into a horizontal arc motion by the horizontal rotary lever, and the arc rotary motion causes the vertical rotary lever to rotate in a point manner. As a result, the switching lever fitted to the lower end of the vertical rotation lever rotates, and the cable length can be switched.

Due to the extension of the device, the vertical rotation lever falls off the switching lever.
