Description

Technical Field

[0001] The utility model relates to the technical field of water turbines, in particular to a multi-blade high-efficiency water turbine. Background Art

[0002] Most modern turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, water from the upstream reservoir is led to the turbine through a water diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tailwater pipe. The higher the water head and the greater the flow rate, the greater the output power of the turbine.

[0003] After searching the public (announcement) number: CN202203023U, a high-efficiency and energy-saving water turbine was found. The turbine is characterized in that a plurality of blades are evenly arranged on the base circle of the water wheel. The space between the blades and the end panels in front and behind the water wheel axis form many water blade cavities. An arc-shaped water baffle is installed on the horizontal line at the center of the water impeller, and its inner curvature matches the outer curvature of the water impeller. A water inlet is opened in the center of the water baffle, which leads to the water blade cavity. The water entering the water blade cavity from the middle hole of the arc-shaped water baffle is blocked by the front and rear end panels and the arc-shaped water baffle, and the water cannot be discharged without doing work. At this time, there are multiple water blade cavities on one side of the horizontal line at the center of the water wheel that receive external water pressure, forming a gravity eccentricity with the axis to produce high-speed rotation.

[0004] In the process of using the prior art, when connecting the water inlet pipe and the water delivery pipe on the turbine, the connecting flanges on the water inlet pipe and the water delivery pipe need to be fixed, and before connecting and fixing the two sets of connecting flanges, the installation grooves on the two sets of connecting flanges need to be aligned. When aligning the installation grooves, the water delivery pipe needs to be turned over, and the water delivery pipe itself is relatively heavy, which makes the operation inconvenient.

[0005] To this end, we propose a multi-blade high-efficiency turbine. Utility Model Content

[0006] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a multi-blade high-efficiency water turbine.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-blade high-efficiency water turbine, comprising a high-efficiency water turbine body, the outer wall of the high-efficiency water turbine body is provided with a water inlet pipe for water transportation, the front side of the high-efficiency water turbine body is provided with a connecting pipe for water transportation, the rear side wall of the connecting pipe is sealed and connected with a second connecting flange for positioning, the outer wall of the water inlet pipe is movably installed with a first connecting flange for positioning, the front side walls of the first connecting flange and the second connecting flange are both provided with through grooves for positioning and installation, the outer wall of the water inlet pipe is fixedly installed with a fixing ring for limiting position, the fixing ring is located at the front side of the first connecting flange, the inner wall of the first connecting flange is provided with a connecting groove for limiting position, the connecting groove can be movably sleeved on the outer wall of the fixing ring, the fixing ring corresponds to the front side wall of the water inlet pipe, and the outer wall of the fixing ring is fixedly installed with a sealing gasket.

[0008] Preferably, two groups of fixing blocks are fixedly mounted on the outer wall of the first connecting flange. The two groups of fixing blocks are arranged in a front-to-rear horizontal state, and the front side walls of the two groups of fixing blocks are provided with mounting grooves.

[0009] Preferably, the interiors of the two groups of installation connecting grooves are fixedly provided with connecting sliding rods that can be used for limiting positions, and the interiors of the two groups of installation connecting grooves are movable with position adjusting rods.

[0010] Preferably, the outer walls of the two groups of position adjustment rods are provided with threaded grooves, and the outer walls of the two groups of position adjustment rods respectively penetrate the wall surfaces of the two groups of installation grooves that are far away from each other.

[0011] Preferably, the two groups of mounting grooves are internally provided with matching movable clamping plates movably mounted therein, and the two groups of movable clamping plates are threadedly connected to the two groups of position adjustment rods.

[0012] Preferably, the walls of the two groups of position adjustment rods that are separated from each other are fixedly mounted with auxiliary blocks in the shape of a regular hexagon, and the walls of the two groups of auxiliary blocks that are separated from each other are provided with auxiliary slots.

[0013] Beneficial Effects

[0014] The utility model provides a multi-blade high-efficiency water turbine. It has the following beneficial effects:

[0015] (1) A multi-blade high-efficiency water turbine. During use, when installing between a connecting pipe and a water inlet pipe, the connecting pipe can be moved backward and close to the first connecting flange until the rear wall of the connecting pipe and the front wall of the fixing ring fit together. At this time, the first connecting flange is moved forward until the connecting groove is sleeved on the outer wall of the fixing ring. At this time, the first connecting flange and the second connecting flange are close to each other. At this time, the first connecting flange can be rotated to align the installation grooves on the first connecting flange and the second connecting flange. Finally, the two groups of installation grooves can be connected by bolts and nuts. There is no need to flip the entire connecting pipe to align the two groups of installation grooves, which facilitates the overall installation. In addition, since a sealing gasket is fixedly installed on the outer wall of the fixing ring, the sealing performance of the connecting groove and the fixing ring can be increased.

[0016] (2) A multi-blade high-efficiency water turbine. During use, when the installation grooves on the first connecting flange and the second connecting flange are aligned, the two sets of position adjustment rods can be rotated in the forward direction. Under the limiting action of the two sets of connecting slide bars and the two sets of installation grooves, the two sets of movable clamping plates approach each other until the vertical ends of the two sets of movable clamping plates and the outer wall of the second connecting flange are fitted together, which can limit the first connecting flange and improve the stability of the two sets of installation grooves after alignment, thereby facilitating subsequent installation operations. In addition, the auxiliary blocks and the auxiliary clamping grooves can facilitate the rotation of the two sets of position adjustment rods and facilitate the use of the device.
