Description

The utility model relates to mechanical engineering, and more particularly to devices using the physical effect of electro-hydraulic shock.

A known installation using a powerful pulsed action of electro-hydraulic shocks on a piston placed in a cylinder with a liquid to drive a hammer, when an electric discharge is initiated between the electrodes in the liquid, an electro-hydraulic shock occurs, as a result of the above and under the action of its own mass, the piston moves along the guides of the hammer bed, acting on the processed object (L.A. Yutkin: Electro-hydraulic effect and its application in industry; - L.: Mechanical engineering. Leningrad. Department, 1986. - P.135 )

Due to the flat piston working surface, the distance from the discharge zone to the piston surface increases with distance from the longitudinal axis of the piston; the resulting force resulting from the discharge and acting on the piston cannot reach a significant value.

A device is known comprising a strong steel body, into which a massive piston is inserted with a flat working surface and a connecting rod (pusher) connected to a massive inertioid (flywheel), which is frictionally connected directly or through a speed variator to the wheels of the vehicle, the internal cavity of the working chamber is completely filled with an incompressible liquid, for example water, durable electrical insulators are screwed into the chamber wall, and in each

one corrosion-resistant electrode is installed in the insulator, the depth of the insulator in the cavity of the working chamber is sufficient to cause a high-voltage electric discharge between the electrodes after turning on the power switch and the discharge of a high-voltage capacitor pre-charged from a high-voltage power source (RU, No. 2157893, F01B 29/10, F03C 5/00, F04F 1/16, 2000.10.20).

Due to the flat piston working surface, the distance from the discharge zone to the piston surface increases with distance from the longitudinal axis of the piston; the resulting force resulting from the discharge and acting on the piston cannot reach a significant value.

The objective of the utility model is to increase the value of the resulting force of the installation for converting the energy of electro-hydraulic shock into reciprocating motion at a constant value of the energy of electro-hydraulic shock, by maintaining a constant distance from the discharge zone to the piston surface.

The technical result is achieved by the fact that in the installation for converting the energy of electro-hydraulic shock into reciprocating motion, comprising a housing, a piston with a pusher, an electrical insulator screwed into the housing with an internal electrode, a second electrode enclosed in a cavity formed by the internal surface of the housing and the piston, liquid, the housing has a removable cover with an opening for the pusher, contains a spring located coaxially with the pusher and enclosed between the outer wall of the piston and the inner wall of the removable Ryshkov, the second electrode is disposed in the same electrical insulators, and the end surface of the piston facing the electrode is formed as a concave hemisphere.

In addition, the upper inner surface of the housing is made in the form of a convex hemisphere.

To maintain a safe pressure inside the device, the housing is equipped with a safety gas valve, rigidly fixed in the upper part of the housing.

The installation device for converting the energy of electro-hydraulic shock into reciprocating motion is illustrated by drawings, where

figure 1 - the device of the proposed installation,

figure 2 - plot of the distribution of forces on the piston.

Installation for converting the energy of electro-hydraulic shock into reciprocating motion (figure 1) contains a housing 1, the upper inner surface 2 of which is made in the form of a convex hemisphere, a piston 3 with a pusher 4 inserted into the housing 1, an insulator 5 screwed into the housing 1, for example, ceramic , with internal electrodes 6, enclosed in a cavity formed by the inner surface of the housing 1 and the piston 3, a liquid 7, for example water, the housing 1 has a removable cover 8 with an opening for the pusher 4, contains a spring 9, for example The gas safety valve 10, coaxially located coaxially with the pusher 4 and enclosed between the outer wall of the piston 3 and the inner wall of the removable cover 6, is rigidly fixed in the upper part of the housing 1, the end surface 11 of the piston 3 facing the electrodes 6 is made in the form of a concave hemisphere (Fig.2) so that each point (1) of the surface 11 of the piston 3 becomes equidistant from the discharge point (0), (l = const}, therefore, F = const for all points of the surface 11 of the piston 2.

The operation of the installation for converting the energy of electro-hydraulic shock into reciprocating motion is as follows.

A high voltage pulse is applied to the terminals of the electrodes 6 and a breakdown occurs between the working ends of the electrodes 6 deepened into the liquid 7. As a result of electrical breakdown

liquid 7 there is a powerful electric discharge, accompanied by the formation of a shock wave, which has the form of a hemisphere, is evenly distributed throughout the entire volume of liquid 7, and evenly presses on the hemispherical surface 11 of the piston 3. As a result, the piston 3 drives the plunger 4, by which the force it is transmitted to a controlled object (not shown conditionally), while compression of the spring 9 occurs, after the disappearance of the shock wave, the compressed spring 9 returns the piston 3 to its original position. In case of excess of pressure in the liquid 7 of the permissible norm (determined by the strength of the housing), its excess will be released outward through the safety valve 10.

As you can see, unlike the prototype, in the inventive device, the piston surface is equidistant from the discharge zone, as a result of the foregoing, the resulting force arising from the discharge and acting on the piston reaches a significant value, which in turn increases the efficiency of the device.
