ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hydraulic device, and more particularly to a hydraulic device powered by wave, such as the sea wave.
2. Description of the Prior Art
Water has been widely used for generating electricity. But, huge dams are required to be constructed for storing the required water. Various kinds of solar collecting devices have also been widely developed. However, the solar collecting efficiency is still bad and may not be satisfied.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional energy collecting devices.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a hydraulic device powered by wave, such as the sea wave, to generate the required energy or power. The wave may be generated by the gravity between the earth, the moon, and the sun, and may be transformed into the hydraulic force in order to actuate the other facilities or to generate the electricity.
In accordance with one aspect of the invention, there is provided a hydraulic device powered by a wave comprising at least one post for securing on a sea floor, a float for buoyant on the wave, a pump including a housing having an interior provided therein, a piston slidably received in the interior of the housing for separating the interior of the housing into a first chamber and a second chamber, means for coupling the piston to the float, a first pipe coupled to the first chamber of the housing via a first check valve for allowing a fluid to flow from the first pipe into the first chamber of the housing via the first check valve, a second pipe coupled to the first chamber of the housing via a second check valve for allowing the fluid to flow from the first chamber of the housing into the second pipe via the second check valve, a third pipe coupled to the second chamber of the housing via a third check valve for allowing the fluid to flow from the third pipe into the second chamber of the housing via the third check valve, a fourth pipe coupled to the second chamber of the housing via a fourth check valve for allowing the fluid to flow from the second chamber of the housing into the fourth pipe via the fourth check valve, and means for attaching the housing of the pump onto the post. When the piston is moved between the chambers, the fluid may be drawn into the first chamber of the housing from the first pipe and may be forced out of the first chamber of the housing into the second pipe, and may be drawn into the second chamber of the housing from the third pipe and may be forced out of second chamber of the housing into the fourth pipe, such that the fluid forced out through the second and the fourth pipes may be used as the hydraulic energy to actuate or to power the other facilities or to generate the electricity.
The attaching means includes a support disposed on the post, and means for securing the housing to the support and having an adjustable securing device for adjustably securing the housing to the support.
The coupling means includes an extension extended from the piston and coupled to the float and pivotally secured to the float with a pivot pin.
A device is further provided for fastening the float to the post and includes a base secured to the post, the float is pivotally secured to the base with a pivot axle. The float may also be directly and pivotally secured to the post with the pivot axle without the base.
