SU484128A1 - Lever mechanism for extending the instruments of the underwater vehicle - Google Patents

Description

one

The invention relates to marine instrumentation and can be used to extend the device in a working position, installed on various research and search submersible devices such as the bathyscaphe and the bathysphere. To such a kind of instruments, Otos ts, for example, lighting lamps, sensors, acoustic devices, etc., which are installed mainly in the additional part of the apparatus.

In order to avoid damage to devices when lifting underwater vehicles from water and installing them on a vessel carrier, it becomes necessary to lift these devices into special protective niches and automatically move them to the working position when they are submerged in water.

A lever mechanism for advancing devices of an underwater vehicle, such as a bathyscaphe, is known, which includes a bar fixed in a niche of an underwater vehicle, at one end of which the device is mounted, and at the other end is a ball float. However, the weight of the float in the air may not be sufficient to lift the instrument when the apparatus is lifted out of the water.

The purpose of the invention is to provide an automatic extension of the device when the submersible apparatus is immersed in water.

In the proposed lever mechanism to

a ball-shaped float is attached to an open backrest of a thin-and-dusky tank with internal thin-walled transverse bulkheads and openings in its upper part

for the passage of water. Transverse bulkheads serve to retain water in a thin-walled container while it is in air in an angled position.

To ensure the instrument is raised (with

in the air) the starting position should be provided with inequality

Gn / i + GeM / i + G, / i-Gnp / 2 0,

where Gn, GCM, GB, Gnp is the weight of the float, thin-walled tank, water in the tank and the instrument, respectively;

/ 1 and / 2 is the length of the boom arms from the axis of the hinge's reversal to the zeitres of the solid of the float, topmostank capacity, water in the container and the instrument, respectively.

Since the weight of the structure of the thin-walled container is very small, it can be neglected, then

To move the device to its working position when the device is in the water, it is necessary to ensure inequality

(С „-1Г„) / 1 + () 1- (Olr-W, p),

where Wn, W ,, W,

Since the installation space is limited,

.

Pz inequalities (1) with G ,, p С „and Сз 0, the weight of the float in the air may be insufficient to lift the device and raise the apparatus from the water.

Installing an additional load, for example, in the form of lead pigs, can lead to inequality (1), but to a violation of inequality (2), since the weight of the load is greater than the weight of the water it displaces, and therefore the device will not advance in working position.

When installing a thin-walled tank with internal transverse thin-walled bulkheads and openings in its upper part for water passage, the inequalities (1) and (2) are satisfied, since in water W G

FIG. 1 shows the described lever mechanism when the device is in the air; in fig. 2 - the same, when the device is in the water.

The lever mechanism includes a rod 1, at one end of which the device 2 is fixed, and on the other - a float 3 with a thin-walled container 4 attached to it, which has holes 5 at the top for passage

water. Moreover, the container is divided transverse thin-walled bulkheads 6.

The rod in the middle part is mounted on a hinge, which is mounted on a rack 7, having upper 8 and lower 9 stops, ensuring the installation of the Ptanga in the extreme positions. The rack is directly attached to the underwater vehicle, or is part of it.

When immersed in water, the device 2 under the action of its gravity and float 3, having a positive buoyancy (W ,, G, i; WB GB), is automatically pushed down to the stop 9, thereby being set to the working position.

When the apparatus is lifted out of water, the device 2 automatically rises to the upper position, limited by the stop 8, by the weight of the water in the thin-walled tank and the weight of the float.

Subject invention

A lever mechanism for extending the instruments of an underwater vehicle, such as a bathyscaph, includes a bar fixed pivotally in the niche of the underwater vehicle, at one end of which the device is mounted, and at the other end is a ball float, characterized in that the underwater vehicle into the water, to the float of the ball-shaped lever mechanism of the accessory, the thin-walled tank with the inside thin-walled cross-bars is open from below

bulkheads and openings in its upper part for the passage of water.
