Abstract

PURPOSE:To obtain power by swinging connecting rods provided on the both ends of a swinging bar with both end axes as centers by means of expansion and contraction of elements of a shape memory alloy, etc. due to difference in temperatures, to shift the center of gravity, and providing the seesaw movement to said swinging bar. CONSTITUTION:Liquid in an liquid tank is hot while the air above the liquid level W is cold. Accordingly, if the center of gravity of a swinging bar 1 comes to the left side of a shaft 4 as shown in the figure under this condition, the left side of the swinging bar 1 is lowered, connecting rods 6, 6' are inclined leftward, the element 12 of a shape remembering alloy, etc. goes down below the liquid level W and is expanded by heat, being immersed in hot water. Following this, the center of gravity of the swinging bar 1 is shifted, due to construction, to the right side of the shaft 4. In this case, an element 12' is contracted because of being in the air. Thus, when the center of gravity is shifted to the right side, the right side of the swinging bar 1 is lowered and, thereby, the element 12' is pulled downward by means of a wire 9 and immersed in the hot water, while the other element 12 is raised, and contracted in the open air. By repeating these actions, the seesaw movement is carried out, to obtain power.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a center-of-gravity moving type heat engine that expands and contracts a shape-memory base metal element by lAi' + movement to cause seesaw motion, thereby obtaining thrust force. be.

The center of gravity of an oscillating body in which elements such as bimetals, linear shape memory alloys, etc. that expand, contract, or deform due to temperature differences are supported alternately between liquids and gases with temperature differences, or between liquids. The applicant has already developed a heat engine that generates power by moving the oscillator from side to side, but since these elements are located at both ends of a long oscillator, the liquid tank that causes temperature changes in them also needs to be oscillated. It increases in proportion to the length of the moving object.

However, if the surface shape of the liquid tank becomes large, the manufacturing cost of the liquid tank and the loss of heat of the liquid in the liquid tank will also increase.

Therefore, this liquid tank needs to be made very small.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The gravity moving thermal engine according to the present invention will be explained in detail below based on the drawings.

Figure 1 is an explanatory diagram of the principle in which the liquid tank is made smaller so that power can be obtained by a seesaw using a shape memory alloy element.The center of the rocking body C can be swung by a hinge B at the top of the column A. is supported by. Both ends of the rocking body C are bent downward symmetrically about the pivot point. Flexible connecting pipe IJ, which is bent and bent, is wrapped around the rocking body C described later.
This is to allow Fj' to move smoothly.

Shake! On the left and right sides of the IIIJ body C, ice cubes F and F' are respectively fitted, shape memory alloy elements a and al are inserted into the tips, and the lower ends 1111 of the elements G and G' are attached to the rocking body C.
ts=+ at the ends of the flexible connecting tubes E and Fi', and the free end sides are connected to one end of the flexible connecting tubes E and Fi', respectively, and the connecting tubes x, ,
Each other end of m/ is connected to 11(shi) F', F'. The bent portions 1) and D' of the oscillating body C should be placed at the bends 1) and 1) of the oscillator C. Therefore, if the element G cools and shrinks in a cold ventilator, the weight F and the connecting pipe E The element G' on the right side expands due to the heat of the water J in the liquid tank (1') and connects the connecting pipe I. is raised and the weight y moves to the left. In this way, F and F' are riding with B as the center, and the center of the moon η shifts to the left, and one swing C is unbalanced and 1. C and the left side descends. In other words, a see-saw movement is performed, which is repeated by both parents.

Further, by this seesaw movement, L gives inertia to the upper driving wheel and converts the vertical movement into rotational movement and rotates. In this way, the center of gravity is moved to create a seesaw motion, and this motion is mechanically extracted as power.

FIG. 2 shows an embodiment of the gravity transfer type heat engine according to the present invention, in which l is a rocking rod, the center of which is supported by an axis q above a support column 3 set upright in the liquid tank. It has been written. Swing rod l

The upper ends of the connecting rods 7 are connected to each other by a shaft gr.

Also, although not shown, weights may be placed on both ends, or a driving wheel above them may be linked to obtain an injection. The support 3 is provided with feed wheels io and ti supported vertically, and a wire 9 starting from the position of the left axis S of the rocking rod I is hooked to the upper feed wheel IO and lowered by going half a turn. Then, the wire 9 moves the lower feeder wheel // half a turn to the left, then rises, and again causes the upper feeder wheel 10 to turn a half turn to the right.JjIs! Iiυ stick! The right rod shaft is the right shaft 5'.

Also, the feed table 10 parallel to the support column 3. // At predetermined positions on the left and right sides of the wireter located between //2. /-' is cloaked, and those elements/,

The upper ends of the oJ flexible bamboo tubes /3i, /j' are fixed to the pieces lδ, 18' with the ends protruding near both ends of the swinging rod l, and one end of the inner steel Hitr, tt, ' is connected. Rod 6,6'
Connected to Ir1l/4 wires /A, /A) Each other end has holes /7, /7', elements /2, /1! The lower ends of elements /2 and /2' are shortened by heating and cooling a wire through the inside of the wire.

In this case, the liquid in the liquid tank is hot and the atmosphere above the liquid surface W is to be cooled. Therefore, under this condition, 1
i1i p'b t? +/'s oil, the heart is 41+ Hiro's top left as shown in Figure 032! When the left side of the swinging rod l is lowered, the connecting rods 6 and 6' are both connected to the axis S, as shown by the chain lines.

The vertical line M passing through 5' is nodding to the left side of M'.

At the moment of tilting, the elements / and 2 on the left side are shortened and the elements on the right side are expanded, which is different from the drawing. However, from the next moment, a change occurs. That is, the element 12 is exposed to hot water due to heat, and its beak extends below the liquid level.

Due to this stretching, the lower washer 79 of the element l- attached to the shear wire 9 is pushed by the element l, so that ≠4=R'-.

Copper 11M/j whose end is fixed to washer 79 (6) is connecting rod 6
In order to draw around the axis S, the connecting rod 6 is pulled to the right of the fIrj straight line M to a position τ1t.

Then, since the upper part of the connecting rod 6 is connected to the other connecting rod 6' of the swinging rod l by the connecting rod 7, push the other connecting rod 6' and position it on the right side of the conical surface @m'. . Then, the center of gravity of the swinging rod l moves to the right side of the axis t.

In this case, the element 1.2' is shortened since it is entirely in the atmosphere. As the center of gravity shifts to the right in this way, the right side of the swinging rod 1 descends, and the element 72' is pulled downward by the wire and immersed in the hot water, while the other element 72' rises to the atmosphere. , and repeat the above motion to perform the scene motion.

The upper ends of /6' are tied to connecting rods iot and to6', respectively.

Further, the upper ends of the connecting rods lθ4 and 106' are connected by a connecting rod lθ7 as in FIG. 1.

Therefore, this operation is similar to the above, and the notification rod ioq,
Guided by to9', element //2. /16. The connecting rods lo4 and 106' are operated via l16' to change the center of gravity of the swinging rod lθl to perform the sea h movement.

In all of the above elements, the larger the temperature difference, the faster the reaction and the more force is produced.

Figure 6 shows an improvement to the liquid tank, in which two liquids with different specific gravity and temperature are placed in the liquid tank, and at the interface there is a glass having intermediate specific gravity between the two liquids α and B.

A large number of small pieces made of a heat insulating layer 3 made of plastic or the like are suspended, and a swinging rod 1 swings to perform a sea six. In this case, water or other low-temperature liquid is placed in the lowest layer of the liquid 4na, and on top of that is a group of insulating materials 20 made of glass, etc. Furthermore, 4g of liquid IF with low specific gravity is provided, and upper layer liquid α and atmosphere 2 are added.
There is a large temperature difference between /. In this case, a heat insulating layer L' with a small specific gravity is also floated on the upper layer.Which of the accompanying liquids and the lighter liquid σ is to be heated and which is to be cold is selected according to the installation '8% Jlr. In addition, if heat exchangers 22 and JJ are placed in each of the upper and lower liquid layers, and a cooling liquid is sent to one of them and a heating liquid is sent to the other to create a temperature difference between the two liquid layers, heat transfer to the element can be improved. The atmosphere will also be quite good.

Fig. 1-7 shows another embodiment of the liquid 411V type, in which a large number of fins 26 are provided on the top of the liquid type to exchange heat with cold and ground water, and a solar water heater J is installed in the upper liquid layer α. It is effective to exchange heat by flowing hot water from the conduit core f.

Figure t shows the case where the heat engine with seesaw set is made into a shed and applied to a scientific model '4', and a liquid α' such as cold water or the like is placed in a container co' of a pot ζt. A side view is shown using the scene shown in Figure 223 of the thermometer 223, in which the shaft lO1/ from the support 103 is extended long to support the oscillator lθl. , so that it is activated in the center of the valley when installed in a container.

The container holder can be attached to and removed from the edge of the container by appropriate means.

As mentioned above, the present invention utilizes the temperature difference between hot water, cooling, etc. to generate power by applying a seesaw motion to the rocking rod through expansion and contraction using an element, and in order to provide the seesaw motion, the temperature difference is obtained. However, in order to do this, the larger the liquid tank, the greater the loss of heat, so to reduce the difference, the swing rod should be shortened to make the liquid tank smaller.

However, shortening the swinging rod means that the swinging of the swinging rod is small, and even when the swinging rod is swinging, the range in which the element that operates the swinging rod moves up and down from the liquid to the atmosphere is reduced. Therefore, the present invention
In order to make the top and bottom thicker, a tTJ connection tube is used to transmit the I'll contraction of the element to the connecting rod via the γ111 line passing through the flexible tube, and the center is moved. The element can be completely immersed in the liquid and escape into the atmosphere by increasing the oscillation of the element, increasing the vertical movement of the element, and allowing the element to work more effectively.

Also, if the temperature and force t are insufficient for the turbine to appear, then 2(
Hot water is available not only in hot spring areas but also everywhere. For example, the amount of heat generated at the nation's nuclear power plants currently accounts for approximately 30% of that amount compared to electricity.
Therefore, if such a heat engine could fully utilize this self-heat, the power generated at a nuclear power plant would be Even if the number of power plants is the current number, the same result will be obtained as if the number of power plants were tripled.

Furthermore, if we can utilize cold heat from solar heat, geothermal heat, rivers, underground water, the ocean, etc., the energy sources can be said to be limitless. Therefore, the development of this kind of engine is a stone f.
I believe that even in times of abundance, we cannot let go.
