Technical Field

The invention relates to a facility of a power plant, in particular to a sound insulation and noise reduction device for a wall-penetrating pipeline of a hydraulic power plant.

Background

Hydroelectric power plants are large-scale power equipment, the connection between the equipment often needs to be connected through a through-wall pipeline, and due to the fact that pipeline maintenance is often performed and the increase of pipelines, if the through holes are only drilled on the wall to perform insertion, installation, maintenance and the like of the pipelines, the pipelines are inconvenient to install and maintain, and the pipelines are easy to damage, a common method in the hydroelectric power plants is to directly open a channel opening on the wall, and the pipelines penetrate through the channel opening to be connected with the corresponding equipment (see fig. 1). However, some equipment in the hydraulic power plant can generate great noise (such as a turbine machine room) in the operation process, and the passage opening is closed, so that sound insulation is not convenient, and the working environment of other workshops is seriously influenced. Therefore, it is urgently needed to design a noise device for blocking the channel opening.

Disclosure of Invention

The invention aims to provide a sound insulation and noise reduction device for a wall-through pipeline of a hydraulic power plant, which solves the problems.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a device of making an uproar falls in wall insulation of power plant's wall-penetrating pipeline, includes the wall body of treating the installation, set up the passway that the wall-penetrating pipeline of being convenient for passed on the wall body, still including the device of making an uproar falls in the sound insulation, the device of making an uproar falls in the sound insulation falls makes an uproar and constitutes by the board and the installation frame of making an uproar, the board of making an uproar falls in the sound insulation, and through-hole an that the installation frame was embedded in the passway of wall body, the board of making an uproar falls in the sound insulation comprises last plate body, intermediate plate body and lower plate body, it places to overlap in proper order to go up plate body, set up the through-hole a that the large-scale pipeline.

Preferably, the large pipeline is a speed regulator oil inlet and outlet pipeline, the small pipeline is an auxiliary pipeline, and the rubber buffer sleeve is sleeved on the speed regulator oil inlet and outlet pipeline.

Preferably, the width of the middle plate body is smaller than the height of the middle plate body.

Preferably, a through hole c for the small pipeline to pass through is additionally arranged on the lower plate body.

Preferably, the mounting frame is a square frame body, the size of the mounting frame is matched with that of the passage opening, and polyurethane foam layers are filled in gaps between the mounting frame and the wall and gaps between the mounting frame and the sound-insulation noise-reduction plate.

Preferably, the front of installation frame is equipped with the turn-ups of being convenient for the lock on the wall body, the welding of installation frame back has the shelves strip of avoiding making an uproar board release of making an uproar falls in the sound insulation.

Preferably, the sound insulation and noise reduction plate is a sound absorption and noise reduction glass fiber plate.

Compared with the prior art, the invention has the advantages that: a wall-penetrating pipeline sound insulation and noise reduction device is designed for a wall-penetrating channel of a hydropower house, a working area can be effectively isolated, the noise of a water turbine machine room is prevented from being transmitted to influence other working areas, the installation and the disassembly are very convenient, and the safe operation of an original pipeline can not be influenced.
