the drive is powered by ocean waves.
As can be seen from the above description, the utility model provides a floating bucket type sea wave power generation device, which comprises two pumping devices and a driving device; the two water pumping devices are connected with the driving device; the two water pumping devices work alternately; thereby alternate work realizes that this device incessant draws water, and the hydraulic turbine can last operation work, realizes lasting stable energy supply. The seawater is pressed out by utilizing the matching of the cylinder body and the piston, and the extruded seawater has the characteristics of large pressure, high flow speed and the like, and can provide higher mechanical energy for the operation of the water turbine.
Further, the drive device includes a crankshaft;
two connecting rod shaft necks are arranged on the crankshaft, and the two connecting rod shaft necks are coaxially arranged;
the two water pumping devices are symmetrically arranged on the left side and the right side of the crankshaft;
the other ends of the connecting rods of different water pumping devices are correspondingly hinged on different connecting rod shaft necks respectively.
From the above description, the working principle of the device is as follows: because the two connecting rod journals on the crankshaft are coaxially arranged, and the two water pumping devices are symmetrically arranged on the left side and the right side of the crankshaft, when the crankshaft rotates, the two connecting rods on the left side and the right side can be driven to move towards opposite directions, namely when the left connecting rod drives the left piston to perform compression movement towards the left cylinder body, the internal space of the left cylinder body is reduced and the pressure intensity is increased, so that the left cylinder body extrudes outwards for drainage; at the moment, the right connecting rod drives the right piston to move away from the right cylinder body, the internal space of the right cylinder body is increased, the pressure intensity is reduced, and therefore the right cylinder body absorbs water inwards; with the continuous rotation of the crankshaft, the alternating drainage and water absorption of the cylinder bodies on the left side and the right side are completed.
Further, the device also comprises a first check valve and a second check valve;
the first check valve is arranged at the water inlet, and the check direction is opposite to the water inlet direction;
the second check valve is arranged at the water outlet, and the check direction is opposite to the water outlet direction.
Further, the device also comprises a three-way valve;
two water inlet ports of the three-way valve are respectively and fixedly connected with the water outlets of two different water pumping devices;
and the water outlet port of the three-way valve is fixedly connected with the confluence port of the water turbine.
From the above description, the working principle of the device is as follows: when the crankshaft drives the connecting rod, and the connecting rod drives the piston to perform compression movement towards the cylinder body, under the action of positive pressure, the second check valve positioned at the water outlet on the cylinder body is in an open state, and the first check valve positioned at the liquid inlet on the cylinder body is in a closed state, so that the water cannot be discharged from the water inlet in the extrusion drainage process; on the contrary, when the crankshaft drives the connecting rod, the connecting rod drives the piston to move away from the cylinder body, under the action of negative pressure, the second check valve positioned at the water outlet on the cylinder body is in a closed state, the first check valve positioned at the liquid inlet on the cylinder body is in an open state, water absorption is completed, and the water absorption process is ensured not to suck back the extruded seawater from the water outlet. Because the setting of first check valve and second check valve guarantees that two pumping device work in turn can go on smoothly.
Further, the driving device also comprises a buoy and a driving rod;
one end of the driving rod is fixedly connected with one end of the crankshaft;
the other end of the driving rod is hinged with the buoy.
From the above description, the buoy floats on the sea surface, and as the sea waves fluctuate up and down, the buoy drives the driving rod to swing up and down, and the driving rod drives the crankshaft to rotate left and right, so as to provide power for the water pumping device.
Further, the buoy is ship-shaped;
auxiliary cylinders are arranged on two sides of the floating cylinder.
From the above description, it can be seen that the pontoon with the shape of the boat can better react to the fluctuation of the sea waves and generate larger power; the auxiliary cylinder can increase the area and reduce the gravity center, and the buoy is prevented from swinging left and right around one end of the driving rod.
Further, a clutch is also included;
the clutch is disposed at one end of the crankshaft.
From the above description, when extreme weather occurs, the sea surface fluctuates rapidly, the sea fall is large, the buoy fluctuates rapidly along with the sea, the time for the piston to extrude the sea water in the cylinder body is required, and when the extrusion force is too large, the cylinder body and other structural components are easily damaged; the clutch is used for separating the driving rod from the crankshaft when the pressure in the cylinder body is overlarge, so that the overload protection effect is achieved.
Further, the output end of the water turbine is fixedly connected with the power input end of the generator.
As can be seen from the above description, the power of the water turbine is used to transmit to the generator, and the mechanical energy is converted into electrical energy.
