Wherein the counterweight member 1 is fixed with the counterweight beam 2 together, and provide the counterweight gravity by the counterweight member 1, the free end of the deflection rod 4 is supported against the deflection platform 9 and can push against the deflection platform 9 to rotate, the free end of the dead lever 5 is relatively fixed against the inner side of the driving part 10, the counterweight beam 2 is parallel with the deflection rod 4, the connecting rod 3 is parallel with the dead lever 5, and the connecting rods are connected by hinges to form a link mechanism, and the deflection platform 9 which needs to be gravity balanced rotates around the deflection shaft 8, but the link mechanism can only deflect to a certain extent; the same link mechanism may also be provided with more than one set, specifically two sets, in parallel and symmetrically in the vertical direction of deflection as shown in fig. 2, so that the deflection table 9 obtains balanced gravity balance, one end of the lower tension spring 6 is fixed on the driving part 10, one end of the upper tension spring 7 is fixed on the deflection table 9, and the other ends thereof are fixed on the deflection rod 4. Therefore, the moment arms and moments of the deflection platform 9, the upper tension spring 7, the lower tension spring 6 and the counterweight 1 can be automatically adjusted and changed along with the position change of the deflection platform 9, and are always in a relative balanced state under the comprehensive action of the moments, so that the driving part 10 can easily realize the driving or self-locking of the deflection platform 9.
It is understood that the specific structure and materials of the weight member 1, the weight beam 2, the connecting rod 3, the deflecting bar 4 and the fixing rod 5 are not limited to a plurality of specific structures, such as, but not limited to, cylindrical shape, elongated shape or plate-bar combination shape, and metal or nonmetal, etc., and are within the scope of the present invention; the lower spring 6, the upper spring 7, the deflection shaft 8, the deflection table 9, the driving part 10 and the driving mechanism 11, the supporting frame 12, the reflection mechanism 13, and the heat collecting mechanism 14 according to an exemplary embodiment are further related to the specific application of the present invention, and it is understood by those skilled in the art that the present invention is not limited to the specific shape, combination, and material, and the like, and is within the protection scope of the present invention.
The raising of the deflecting table 9 from the lowest position to the position beyond the upper position is performed by sequentially referring to fig. 3, 1, and 4 to 6, and vice versa (specifically, the deflecting table 9 returns to the lowest position after passing the upper position). According to one embodiment of the invention, corresponding to different positions of the deflection table 9, the moment arms and moments of the deflection table 9, the upper tension spring 7, the lower tension spring 6 and the counterweight 1 are automatically adjusted and changed as follows:
firstly, when the deflection table 9 is at the lowest position, specifically as shown in fig. 3, the gravity center force arm of the deflection table 9 is the largest, the counterweight force arm of the counterweight 1 is close to the largest, the distance between two ends of the lower tension spring 6 and the upper tension spring 7 is the shortest, and the counterweight force arm does not work, the moment of the deflection table 9 is equivalent to the counterweight moment of the counterweight 1, so that the driving part 10 can easily realize the driving or self-locking of the deflection table 9;
secondly, when the deflection table 9 rises from the lowest position to the deflection rod 4 is in the horizontal position, as shown in fig. 3 and fig. 1 in particular, the free end of the deflection rod 4 abuts against and pushes the deflection table 9 to rotate together under the action of the counterweight gravity of the counterweight member 1, the distance between two ends of the upper tension spring 7 is kept to be shortest and does not work, the distance between two ends of the lower tension spring 6 is gradually increased, the tension force is gradually increased, the gravity moment arm of the deflection table 9 is slowly reduced, the counterweight moment arm of the counterweight member 1 is maximized, the moment of the lower tension spring 6 and the moment of the deflection table 9 are equivalent to the counterweight moment of the counterweight member 1, so that the driving part 10 can easily realize the driving or self-locking of the deflection table 9, and vice versa (particularly, the deflection table 9 reversely lowers to the lowest position when the deflection rod 4 is in the horizontal position);
when the deflection platform 9 continuously rises to a certain height from the position where the deflection rod 4 is in the horizontal position, as shown in fig. 1 and fig. 4, the free end of the deflection rod 4 continuously abuts against and pushes the deflection platform 9 to rotate together under the action of the counterweight gravity of the counterweight member 1, the distance between two ends of the upper tension spring 7 is kept shortest and still does not work, the distance between two ends of the lower tension spring 6 is continuously increased, the tension force is continuously increased, the gravity moment arm of the deflection platform 9 is continuously decreased, the counterweight moment arm of the counterweight member 1 is changed to be decreased, the moment of the lower tension spring 6 and the moment of the deflection platform 9 are equivalent to the counterweight moment of the counterweight member 1, so that the driving part 10 can easily realize the driving or self-locking of the deflection platform 9, and vice versa (particularly, the deflection platform 9 is reversely lowered from a certain height to the position where the deflection rod 4 is in the horizontal position);
fourthly, when the deflection table 9 is continuously lifted to a vertical high position from a certain height, as shown in fig. 4 and 5 in particular, the deflection rod 4 is fixed by the structure of the driving part 10, so that the deflection rod 4 is not in contact with the deflection table 9 and the counterweight 1 is not acted any more, at this time, the counterweight arm of force of the counterweight 1 is also minimum, the distance between two ends of the lower pull spring 6 is maximum, the tension force is maximum, the distance between two ends of the upper pull spring 7 is not large, the free state is still kept and the effect is not exerted, the deflection table 9 leaves the free end of the deflection rod 4 but the gravity arm of force thereof is gradually reduced, namely the moment of the deflection table 9 is also gradually reduced, so that the driving part 10 can easily realize the driving or the self-locking of the deflection table 9, and vice versa (particularly, the deflection table 9 is reversely lowered to a certain height from the vertical high position);
fifthly, after the deflection table 9 continues to deflect beyond the vertical high position, specifically as shown in fig. 5 and 6, the balance weight 1 does not work, the distance between the two ends of the upper tension spring 7 is gradually increased, the tension is gradually increased, the moment of the upper tension spring 7 is equivalent to that of the deflection table 9, so that the driving portion 10 can easily realize driving or self-locking of the deflection table 9, and vice versa (particularly, the deflection table 9 reversely returns to the vertical high position after passing the vertical high position).
In fact, in the counterweight devices in other prior art, single-rod balance is adopted or no connecting rod device capable of being automatically adjusted is adopted, and the comprehensive moment can hardly be ensured to be always balanced, so that a driving motor with higher power and a complex self-locking mechanism are required to be selected, unnecessary equipment cost is increased, daily energy consumption is serious, and how to simply, efficiently and lowly realize the gravity balance of the eccentric rotating mechanism becomes a technical problem in the field; the connecting rod type counterweight device with the bidirectional tension spring adjustment can automatically adjust the counter moment of the counterweight device and the counter moment formed by the tension change of the upper tension spring and the lower tension spring according to the position of the eccentric rotating mechanism, so that the comprehensive effect of the integral moment is always relatively balanced, the motor power requirement of the driving part can be greatly reduced, and the self-locking can be realized in a simple mode.
