Embodiment Construction

[0017] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0018] Efficient noise reduction distribution boxes, such as figure 1 As shown, the distribution box body 1 is included, and a high-efficiency noise reduction device is installed inside the distribution box body 1. The high-efficiency noise reduction device includes a foamed latex shell 5 and a foamed latex board 2, and one side of the foamed latex shell 5 The foamed latex board 2 is installed, and the other side of the foamed latex shell 5 is matched with the inner wall of the distribution box body 1. Several sound-absorbing grooves 4 are provided on the foamed latex board 2, and the cross-section of the sound-absorbing groove 4 is isosceles trapezoidal. The groove...

Abstract

The invention relates to an efficient noise-reducing distribution box which comprises a distribution box main body, wherein an efficient noise-reducing device is arranged in the distribution box main body; the efficient noise-reducing device comprises a foaming latex shell and a foaming latex plate; the foaming latex plate is arranged on one side of the foaming latex shell; the other side of the foaming latex shell is matched with an inner wall of the distribution box main body; and a plurality of silencing slots are formed in the foaming latex plate. According to the invention, an efficient noise-reducing plate, a magnet and chloroprene rubber are combined; the efficient noise-reducing plate is magnetic; and when noise passes by the efficient noise-reducing plate, the efficient noise-reducing plate deforms and is capable of absorbing the noise energy, and meanwhile, the magnet arranged on the chloroprene rubber is capable of buffering the deformation of the efficient noise-reducing plate under the effect of magnetic force, so that the absorbing efficiency of the efficient noise-reducing plate for the noise can be increased and the noise-reducing effect can be promoted.

Description

technical field [0001] The invention relates to a distribution box, more precisely a high-efficiency noise reduction distribution box. Background technique [0002] Distribution box is the box body that protects electrical equipment, requires to be assembled in closed or semiclosed metal safe by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Existing power distribution boxes will generate a lot of noise during operation. Most of the existing noise reduction methods are to install sound insulation panels. The construction effect is not good, and noise reduction and sound insulation cannot be achieved well. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency noise reduction distribution box, which can solve the above problems. ...
