Description

A boat-type double-rod oscillating float energy harvesting device

technical field

The utility model relates to an energy collection device, in particular to a boat-type double-rod oscillating float type energy collection device.

Background technique

Energy is the material guarantee for the survival and development of human society, and the basis for national economic and social development. Since the oil crisis in the 1970s, energy issues have always been the focus of the international community. With the depletion of oil and other fossil energy sources and the global concern about climate change caused by greenhouse gas emissions, low-carbon, energy-saving and the development and utilization of renewable energy It is becoming the theme of world energy development.

The ocean accounts for 71% of the total area of the earth, and wave energy has become one of the most promising marine energy sources due to its large quantity, wide distribution, and multiple acquisition methods.

A wave energy generation system generally includes three stages of energy conversion. The primary conversion system is in direct contact with the waves to capture the wave energy. The energy conversion process is mainly manifested as the conversion of fluid kinetic energy into mechanical energy; the secondary energy conversion system is driven by air turbines or water turbines or short-term storage of mechanical energy to convert it into rotational energy. Kinetic energy is more suitable for driving the generator movement; the three-stage conversion process is mainly through the electromechanical conversion of the generator, and finally completes the power generation process from wave energy to electrical energy.

The oscillating float type is evolved from the oscillating water column type. The oscillating float type uses air as the conversion medium. Under the impact of wave force, the oscillating water column in the device keeps impacting, causing the air in the upper half of the air chamber to do forced movement, and the air reciprocates through the air outlet hole on the upper right of the air chamber, so that the air in the air chamber reciprocates through the nozzle , install an air turbine at the nozzle, and connect the turbine shaft with the generator, then the compressed airflow can be used to drive the turbine to rotate and drive the generator to generate electricity. The oscillating buoy type wave energy generating device is composed of a floating body, an energy conversion mechanism, a generator and a protective shell. The floating body acts as a wave receiver, and the energy collected by it is transmitted to the energy conversion mechanism and converted into stable hydraulic energy. The hydraulic motor converts the hydraulic energy into stable rotational mechanical energy, and then drives the generator to generate electricity.

The existing oscillating float type generally has the problems of large impact on the float, easy damage, poor reliability and low energy conversion efficiency.

According to the above solution, the lower float vibration transmission mechanism includes a lower support rod and a semi-disc weight. The lower support rod is fixedly installed on the bottom of the lower float, and the upper part is affixed to the bottom of the semi-disc weight. When the lower float is placed horizontally, the two hinge points of the half-disk weight are on the same horizontal plane.

According to the solution above, the upper float oscillation transmission mechanism includes a first spring, a second spring, and an upper support rod. One end of the first spring is hinged with the upper piston rod of the first double-rod piston cylinder, one end of the second spring is hinged with the upper piston rod of the second double-rod piston cylinder, the other end of the first spring is fixedly connected with the upper float, and the second The other end of the spring is fixedly connected with the upper float, the upper support rod is installed at the center of the upper surface of the lower float, the bottom is fixedly connected with the lower float, the top is hinged with the upper float, and the axis of the first spring is parallel to the axis of the second spring.

According to the solution above, the upper and lower float connection mechanism includes a first rubber membrane and a second rubber membrane. The first rubber membrane surrounds the first spring, the second rubber membrane surrounds the second spring, and the axis of the first rubber membrane is vertically parallel to the axis of the second rubber membrane.

According to the solution above, the oscillation energy collection mechanism includes a first double-rod piston cylinder, a second double-rod piston cylinder, an oil-up passage, and a down-oil passage. The upper oil chamber of the first double-rod piston cylinder is connected with the upper oil chamber of the second double-rod piston cylinder to form an oil passage; the lower oil chamber of the first double-rod piston cylinder is connected with the lower oil chamber of the second double-rod piston cylinder Oil access. The piston rod of the first double-rod piston cylinder is vertically parallel to the piston rod of the second double-rod piston cylinder.

According to the solution above, the superconducting magnetic fluid power generating mechanism includes a first superconducting magnet, a second superconducting magnet, a third superconducting magnet, and liquid metal. A first superconducting magnet is arranged above the oil passage, a second superconducting magnet is arranged between the lower part of the oil passage and the upper part of the lower oil passage, and a third superconducting magnet is arranged under the lower oil passage. The superconducting magnet generates a magnetic field and electromagnetic induction lines, and the liquid metal flows continuously in the first double-rod piston cylinder, the second double-rod piston cylinder, the oil-up passage, and the oil-down passage.

The beneficial effect of the utility model is that the ocean wave energy is converted into swing kinetic energy, and the swing kinetic energy is directly converted into electric energy by using a superconducting magnet magnetic field fluid power generation mechanism. As the wave floats, the center of gravity of the semi-disc's gravity shifts, which in turn causes the piston rod of the double-rod piston cylinder to pull or press, so that the liquid metal moves back and forth in the two oil passages, cutting the magnetic field generated by the magnet. Induction electromotive force generates electricity. Double-rod piston cylinder is adopted, and the collection efficiency is high. There is a gravity ball in the upper float, which improves the sensitivity of the entire float, and the entire device is installed in the float, thereby avoiding the impact of waves, increasing reliability and extending service life. The structure is simple and reliable, and the cost is low.

As shown in Figure 2, the working process of the present utility model is:

The up and down vibration of the waves causes the left and right swings of the lower float 2. When the crest of the wave comes from the left, the lower float 2 moves to the right as the waves move. Since the lower float 2 is connected with the semi-disc weight 17 through the lower support rod 1, the center of gravity of the semi-disc weight 17 will Offset, so that the hinge point of the lower piston rod of the semi-disc weight 17 and the first double-rod piston cylinder 3, the hinge point of the lower piston rod of the second double-rod piston cylinder 15 are not on the same level, the first double-rod piston The lower piston rod of the cylinder 3 moves downwards and is pulled, and the lower piston rod of the second double-rod piston cylinder 15 moves upwards and is pressed, and the liquid metal in the first double-rod hydraulic cylinder 3 and the second double-rod hydraulic cylinder 15 is It will move back and forth in the oil lowering passage 4, because the first superconducting magnet 12, the second superconducting magnet 14, and the third superconducting magnet 16 generate magnetic lines of induction, resulting in an induced current.
