Description

Technical Field

[0001] This utility model relates to the technical field of turbine housing structure for water turbines, specifically a split-type housing structure for a water turbine. Background Technology

[0002] A turbine-water turbine is a hydraulic machine that uses the kinetic and potential energy of water flow to drive a turbine to rotate, converting water energy into electrical energy. Turbine-water turbines are mainly used for hydroelectric power generation. A turbine-water turbine is a type of turbine, which is an engine that uses fluid to generate power by passing through rotating blades. The turbine is protected by an outer casing.

[0003] For example, Chinese patent CN221779560U discloses a turbine-water turbine, which includes a U-shaped support. Lifting components are provided at the top of the U-shaped support and near the left and right ends. Each lifting component includes two fixed blocks, and a roller is rotatably connected between the two fixed blocks. Steel wire ropes are wound around the outer walls of the rollers in both lifting components. The bottom ends of the two steel wire ropes are connected to a turbine-water turbine power generation component. The turbine-water turbine power generation component includes a semi-circular base plate. Rectangular fixing frames are provided on the front and rear sides of the top of the semi-circular base plate, and a turbine is rotatably connected between the two rectangular fixing frames. This turbine-powered unit features two lifting components that operate synchronously. These components adjust the height of the turbine-powered unit by winding and unwinding the steel wire rope, allowing it to adapt to changes in water level and move below the water surface. Traditional turbine casing structures are often large and modular, requiring numerous connection and fixing points during assembly. The large size of the casing makes precise alignment difficult, leading to deviations during assembly and affecting performance. Therefore, a modular turbine casing structure is proposed to address these issues. Utility Model Content

Then, the upper connecting plate and the lower connecting plate are positioned and fixed by inserting the positioning rod, so as to avoid displacement during the installation process.

[0013] Preferably, the outer surfaces of both the lower connecting plate and the upper connecting plate are provided with a plurality of fixing grooves, and fixing bolts are fixedly installed inside the fixing grooves.

A hanging plate 23 is fixedly installed on the top outer surface of the upper housing 2. The outer surface of the hanging plate 23 has a lifting hole. When assembling the upper housing 2 and the lower housing 1, the upper housing 2 is moved above the lower housing 1 by connecting to the hanging plate 23 through a lifting device.

[0025] In this embodiment, the upper housing 2 is disposed above the lower housing 1. A lower connecting plate 22 is fixedly installed at the bottom end of the upper housing 2. A positioning component is provided between the upper connecting plate 12 and the lower connecting plate 22.

The lower connecting plate 22 at the bottom end is pushed inward along the upper edge 13 to ensure the stability of the installation.

[0026] The upper edge 13 has slots 14 on both outer surfaces. A positioning rod is inserted into the slot 14, and one end of the positioning rod passes through the slot 14 and is inserted into the positioning groove 25 on both outer surfaces of the lower connecting plate 22. When the upper connecting plate 12 and the lower connecting plate 22 are precisely aligned, the slots 14 on both sides of the upper edge 13 will correspond to the positioning grooves 25 on both sides of the lower connecting plate 22. Then, the upper connecting plate 12 and the lower connecting plate 22 are positioned and fixed by inserting the positioning rod to avoid displacement during installation.

Fixing bolts are fixedly installed inside the fixing grooves 24, and the lower connecting plate 22 and the upper connecting plate 12 are fixedly connected by fixing bolts. The fixing bolts are sequentially inserted into the fixing grooves 24 to install and fix the upper shell 2 and the lower shell 1.

[0028] The working principle of this embodiment is as follows:

[0029] When assembling the upper shell 2 and the lower shell 1, the upper shell 2 is connected to the lifting plate 23 by the hoisting equipment. Then, the upper shell 2 is moved above the lower shell 1, and the lower connecting plate 22 at the bottom is pushed inward along the upper edge 13 to ensure the stability of the installation. When the upper connecting plate 12 and the lower connecting plate 22 are precisely aligned, the slots 14 on both sides of the upper edge 13 will correspond to the positioning slots 25 on both sides of the lower connecting plate 22. Then, the upper connecting plate 12 and the lower connecting plate 22 are positioned and fixed by inserting the positioning rod to avoid displacement during the installation process. Then, the fixing bolts are installed in the fixing slots 24 in sequence to install and fix the upper shell 2 and the lower shell 1.
