Ice jam liquidating device. RU patent 2255173.

FIELD: ice breaking equipment, particularly means for ice jam liquidation and for prevention of floods caused by river ice jams.

SUBSTANCE: device comprises breaking anchor and rope. Breaking anchor has lower part to be opened in water after ice jam breaking. The lower part is connected to upper anchor part and provided with elastic sealed vessel with compressed gas cylinder arranged inside it. Sealed vessel with cylinder is connected to upper part of breaking anchor with rope and has negative floatability. Cylinder comprises valve to be opened in response to rope tightening. Upper end of breaking anchor is provided with limiting washer, which remains on ice surface after ice jam breaking with breaking anchor and providing anchor fixation inside ice jam.

EFFECT: increased efficiency of ice jam breaking.

Method for blasting and device for its realization / 2252393
The invention concerns the method for blasting, according to which an elastic envelope is placed in a limited volume of space, filled with a combustible mixture of fuel gases and oxidant and blown up by a trinitrotoluene charge, in this case propane, butane, methane or a mixture of these fuel gases are used as fuel gas.

Ice jam elimination method / 2250956
Proposed method comes to breaking ice jam by vibration generated by wave generator of positive buoyancy inside which vibrator is installed. Wave generator is placed in ice jam close to its free edge.

Ice jam breaker / 2250955
Invention relates to ice breaking devices and it can be used for eliminating jam to prevent flooding at ice jams on rivers. Proposed ice jam breaker consists of tractor with bulldozer installed on telescopic rods in nose part of tractor. Lower edge of bulldozer is made to provide self-cutting of blade into ice under gravity at extension of rods or moving tractor forward, and self-release from ice when pulling rods back, moving tractor backwards or debacling of hummocked ice fields downstream. Telescopic rods are secured on tractor by means of ball joints, and on bulldozer, by means of cylindrical joints for setting them into motion in horizontal and vertical planes by means of hydraulic cylinders. Hermetically sealed container can be mounted on bulldozer to provide positive buoyancy of the latter.

Method of braking ice cover / 2250178
Proposed method is performed by means of submarine ship (2) running under ice (1) at resonance speed and exciting resonance flexural gravitational waves (3). After excitation of flexural gravitational waves (3) in ice (1), ship (2) is braked abruptly for forming hydraulic impact and at moment when first trough (7) of flexural gravitational wave (3) reaches midship section (8) of ship, as determined by means of shipboard echo sounder (9), ship makes fast dive forming rarefaction area (11) above upper portion of ship (2); horizontal component of speed is increased for retaining the resonance mode.

Method of breaking ice cover / 2249076
Proposed method is performed with the aid of hovercraft running at resonance speed. Ice cover is additionally acted on by radio radiation at frequency of 109 to 1010 Hz by means of generator which is located on extensible rod on board the ship. Generator forms hydraulic impact under highest point of crest of flexural gravitational waves and amplitude of this wave is increased when hovercraft runs along edge of ice cover.

Method of breaking ice cover / 2249075
Proposed method is performed by means of hovercraft running at resonance speed. Ice cover is additionally acted on by radio radiation at frequency of 106 to 107 by means of generator which is mounted on extensible rod on board the ship. Temperature of ice is increased and its strength is decreased by operation of generator during performance of ice breaking work by resonance method.

Method of breaking ice cover / 2249074
Ice is broken when submarine ship has no way on by inclining her to maximum angle of list and imparting rotary motion relative to vertical axis coinciding with vertical main axis of inertia of ship and added mass of water formed during rotation of ship.

Method of breaking ice cover / 2249073
Proposed method includes excitation of resonance flexural gravitational waves in ice and creation and change of aerodynamic lift force at frequency of resonance flexural gravitational waves. In the course of motion of ship, alternating aerodynamic lift force is created at frequency of resonance flexural gravitational waves by turning the horizontal plates to positive and negative angles of attack towards incoming flow of air. Plates are mounted on upper deck. Angles of attack are periodically changed at frequency of said waves.

Method for destruction of ice or soil cover / 2246693
The method consists in placement of parachute systems with ammunition on the flight vehicle, their delivery to the preset point, release and blast of ammunition. Elongated flexible explosive charges with initiating devices with a preset delay time connected with one end to penetrators, and with the other end - to the parachutes, assembled in packing cases, are used as ammunition. After the release, the parachute systems turn the flexible explosive charges to the rectilinear position with the penetrators down, separate them from the parachute systems, and the initiating devices are systems, and the initiating devices are remotely cocked.
