Abstract

DC60 (08/09/57) This counterweighted water turbine has four rotor arms shaped like a plus sign. These arms support the turbine blade shafts. The four rotor arms are connected to the rotor shaft. The turbine blades are flat sheets of material, and a shaft is attached to one edge of the blade for mounting it to the rotor arms. A counterweight arm is fitted to the inner end of the shaft, and another counterweight is attached to the other end of the counterweight arm to balance the blades. The rotor rotates due to the water flow. Blades moving in the same direction as the water flow are pushed to open the blade face, creating a vertical cross-flow pattern. These blades are locked in this position by the counterweight arms which lock onto the rotor arms. Blades moving against the water flow are easily lifted by the current. Due to the counterweight balancing the weight of the turbine blades, the rotor shaft is fitted onto the support beam at the center, with bearings supporting its rotation. A pulley is attached to the top end of the rotor shaft for power transmission. Buoys are attached to both ends of the support beam; these buoys not only support the rotor weight but also act as water-moving devices. A counterweight-lifted water turbine has four rotor arms, shaped like a plus sign, which support the rotor shafts. These four rotor arms are connected to the rotor shaft. The turbine blades are made of flat material, and a shaft is threaded through one edge of the blade to mount it to the rotor arm. The blade shaft is threaded parallel to the rotor arm, and a counterweight arm is attached to the inner end of the shaft. Another counterweight is attached to the other end of the counterweight to provide balance. The rotor rotates due to the driving force of the water flow, with the blades rotating at the highest point. Moving in the same direction as the water flow, the turbine blades are pushed to open the water-flow face. The turbine blades are positioned vertically across the water flow and locked in this position by counterweight arms that lock onto the rotor arms. The blades moving against the water flow are easily lifted by the current due to the counterweight balancing their weight. The rotor shaft is mounted on a support beam at the center, with bearings supporting its rotation. Pulleys are attached to the top of the rotor shaft for power transmission. Buoys are placed at both ends of the support beam; these buoys not only support the rotor but also act as a water-moving device.

Claims (1)

1. A counterweighted water turbine consists of two main parts: a stationary part and a moving part. The stationary part consists of the support beam (8), two buoys (9), a water barrier (10), and a water barrier (11). The moving part consists of the rotor shaft (1), four rotor arms (2), four turbine blades (3), four counterweight arms (5), four counterweights (6), and a pulley (7). The rotor shaft (1) is mounted in the center of the support beam (8) with bearings supporting its rotation. At the lower end of the rotor shaft, it serves as a connecting set for the four rotor arms (2), which are connected in a manner that The plus sign (+) turbine blade (3), which is made of flat sheet material, has a shaft (4) fitted onto one edge of the blade. Both ends of this shaft (4) are fitted onto the rotor arm (2) at supports (2a) and (2b), parallel to it. A special feature of the counterweighted water turbine is that a counterweight arm (5) is fitted onto the inner end of the shaft (4), and a counterweight (6) is attached to the other end of this counterweight arm (5). This counterweight acts as a counterweight to balance the turbine blade (3), allowing it to be easily lifted when moving against the flow of water. Another function of the counterweight arm (5) is to act as a locking mechanism to the rotor arm (2), where the counterweight arm (5) locks into the rotor arm. (2) Only when the turbine blades (3) are pushed by the current to move in the same direction as the current, when the counterweight arm (5) locks into the rotor arm (2), the turbine blades (3) will be in a vertical position facing the current. At both ends of the support beam (8) there are buoys (9) to support the entire turbine assembly so that it can float on the water. These buoys (9) are designed to also act as a herding device to increase the speed of the current. They are designed so that the ends of the buoys facing the current are curved like a trumpet. In addition, they are designed to have a water barrier (10) and a water barrier (11).
