A device that uses energy marine� waves / Leon Mate, Stolberg The Mangus, Andrew Savin]. The disadvantage of this device is the impossibility of its direct use on vehicles without additional changes, in particular the stator of the generator cannot be installed on the anchor, also there is no possibility of contact with the external fluid, the motion of which is used in this device.
The claimed invention is directed to solving the problem of simplifying and increasing the efficiency of production of electrical energy for low-power Autonomous devices installed on moving objects.
The task arises when designing and building an Autonomous transmission and reception devices, satellite trackers, etc.
The essence of the invention consists in that in a device located on a moving object entered communicating vessels with liquid, two connectors, two Converter of mechanical energy into electrical energy, two floats located in the left and right communicating vessels, which are United with floats through the connectors a mechanical energy Converter, the outputs of which are combined and connected to the output device.
Functional diagram of the device shown in Fig. 1, where for clarity of presentation introduced the coordinate system OXY, associated with the device.
Mouth�eusto consists of communicating vessels with the liquid 1, floats 2ii=1,..., 2, connectors 3i, i=1,..., 2, transducers of mechanical energy into electrical energy 4i, i=1,..., 2.
Floats 2i, i=1,..., 2 are located in the left and right communicating vessels on the surface of the liquid. The converters of mechanical energy into electrical energy 4i, i=1,..., 2 are located above the communicating vessels and is connected to the floats through the connectors 3i, i=1,..., 2. Converter of mechanical energy into electrical energy 4i, i=1,..., 2 may be made of, for example, in the form of a magnet is rigidly connected with the connector and moving freely inside the induction coil.
In the initial position (when no acceleration), the liquid in communicating vessels is evenly distributed on the two vessels. The fluid motion and the movement of the floats, and thus the generation of electrical energy, are missing.
The device is located on a moving object and rigidly connected with it in such a way that the OX axis of the device coincides with the direction of movement of the object.
The device operates as follows.
In the presence of the acceleration of a moving object in the negative direction of the OX axis of the liquid in communicating vessels 1 under the action of inertial forces (FI1(Fand= -mW, where m is the mass of the liquid, W is the projection of the apparent acceleration on the OX axis) begins to move from levov� vessel to the right. As a result, the liquid level in the vessel begins to rise (in the left - down). The float 22under the action of buoyant force (Fa=ρgV, where ρ is the fluid density, and g is a constant coefficient, V is the volume of liquid) is moved upward (float 21- down) and through the connector 32actuates the Converter of mechanical energy into electrical energy 42(at the same time the float 21through the connector 31actuates the Converter of mechanical energy into electrical energy 41): occurs in the device to generate electric energy. Changing fluid levels, movement of floats 21, 22and the power generation is continued until the maximum value of the liquid level in the vessel. Then the floats 21, 22stop and electric power generation is terminated.
If you reduce the apparent acceleration of the liquid under the action of gravity FT2from the right vessel begins to move into the left receptacle. As a result, the liquid level in the vessel begins to decrease (in the left - to grow). The float 22under the action of gravity starts to fall and through the connector 32affects the Converter of mechanical energy into electrical energy 42(at the same time podnimaushii� float 2 1through the connector 31actuates the Converter of mechanical energy into electrical energy 41): the device again induces the production of electrical energy. With equal levels of liquid in communicating vessels 1 floats 21, 22stop and electric power generation is terminated.
In the presence of the acceleration of the object in the positive direction of the OX axis to generate electric power is similar to the foregoing.
Thus, when acceleration or deceleration of the object, the output will be a voltage that can be used for Autonomous power a low power electric devices.
The simplicity of inertia of the generator and its autonomy makes it very promising when used in stand-alone devices for information processing or transmitting devices.
Inertial generator containing a Converter of mechanical energy into electrical energy, characterized in that it introduced communicating vessels with liquid, two connectors, the second Converter of mechanical energy into electrical energy, two floats located in the left and right communicating vessels, which are United with floats through the connectors a mechanical energy Converter, the outputs of which about�United and connected to the output of the device.
