Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a high-efficiency noise reduction distribution box. Background Art

[0002] In the industrial and commercial fields, the distribution box is a key device for distributing and controlling the power supply. The traditional distribution box performs well in the power distribution function, but has some shortcomings in noise control.

[0003] Existing distribution boxes are usually constructed of metal materials, such as steel plates or aluminum alloys, to provide structural strength and durability. However, these metal materials have good performance in conducting sound waves, so the noise generated during the power distribution process will be transmitted through the box to the surrounding environment, causing noise pollution in the workplace.

[0004] In addition, since traditional distribution boxes lack specialized noise reduction structures and materials in their design, noise cannot be effectively controlled and absorbed. This results in high noise levels in the working environment, which has a negative impact on personnel health and productivity. Especially in noise-sensitive places such as hospitals, offices, laboratories and residential areas, the need for noise control is more urgent.

[0005] At the same time, the existing distribution boxes also have some problems in terms of stability. Due to the lack of special shock absorption and fixing mechanisms, the distribution boxes may be affected by vibrations during operation and produce noise. This will have an adverse effect on the normal operation and life of the equipment, and also cause trouble for the stability of the working environment.

[0006] In summary, the traditional distribution box has some shortcomings in noise control and stability. In order to meet the demand for a quiet and stable working environment, a more efficient noise reduction distribution box design is needed, which combines a noise reduction cavity, a noise reduction core and a stability enhancement mechanism to effectively reduce noise transmission and improve the stability of the equipment. Utility Model Content

[0007] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a high-efficiency noise reduction distribution box.

[0008] To achieve the above object, the technical solution of the utility model is implemented as follows: an efficient noise reduction distribution box, comprising an external chassis of a distribution cabinet and a base, the external chassis of the distribution cabinet is installed inside the mounting card slot provided on the top surface of the base, and noise reduction cavities are provided inside the upper, lower, left, right and rear side box walls of the external chassis of the distribution cabinet, and a noise reduction core is installed inside each of the noise reduction cavities;

[0009] The noise reduction core specifically includes the following structure:

[0010] A first noise reduction layer distributed inside the noise reduction cavity close to the space inside the box;

[0011] An inner reinforcement layer distributed on the outer side of the first noise reduction layer;

[0012] A second noise reduction layer distributed on the outer side of the inner reinforcement layer;

[0013] A flame retardant layer disposed on the outer side of the second noise reduction layer;

[0014] The specific structure of the first noise reduction layer is set as:

[0015] Inner and outer positioning plates are arranged parallel to each other;

[0016] A bent noise reduction plate is distributed between the inner positioning plate and the outer positioning plate.

[0017] Preferably, a shock-absorbing pad supported on the bottom surface of the outer chassis of the power distribution cabinet is also provided inside the installation slot.

[0018] Preferably, a side positioning plate is provided at the top of the installation slot and is attached to both sides of the bottom of the outer chassis of the power distribution cabinet.

[0019] Preferably, the inner positioning plate, the outer positioning plate and the bent noise reduction plate are all made of solid sound-absorbing board material.

[0020] Preferably, the inner reinforcement layer is entirely made of fluororubber.

[0021] Preferably, the second noise reduction layer is entirely made of a sound-absorbing board material with a plurality of honeycomb holes formed on the surface.

[0022] Preferably, the flame retardant layer is made of flame retardant board material.

[0023] The beneficial effects of the utility model are embodied in:

[0024] Reduce noise transmission: The distribution box adopts a full range of noise reduction design, including a noise reduction chamber and a noise reduction core. The noise reduction chamber covers all directions of the distribution box, and the noise reduction core effectively absorbs and disperses noise energy through a multi-layer structure. In this way, both the noise generated inside the distribution box and the noise in the external environment can be effectively reduced, providing a lower noise working environment.

[0025] Improved stability: The outer chassis of the distribution box is fixed and supported by the mounting slots and shock-absorbing pads of the base, which can reduce vibration and improve overall stability. The design of the side positioning plate further enhances the positioning effect of the distribution box, ensuring that the equipment will not generate noise due to vibration during operation.

[0026] High-efficiency sound-absorbing materials: The noise reduction core adopts a multi-layer structure, in which the first noise reduction layer uses a specially constructed bending noise reduction board to achieve the primary noise reduction effect, and the inner reinforcement layer and the second noise reduction layer further improve the sound absorption efficiency and sound insulation effect. The material selection is mainly solid sound-absorbing board, fluororubber and sound-absorbing board, which can effectively absorb and reduce the transmission noise.

[0027] In summary, this high-efficiency noise reduction distribution box has obvious beneficial effects in terms of noise reduction, improved stability, good sound absorption, etc. It can provide a quieter and more stable power equipment operation environment for the working environment, and improve the comfort and safety of users.

[0039] Please refer to the instruction manual Figure 1-Figure 3 , the utility model provides a high-efficiency noise reduction distribution box:

[0040] Distribution box structure design

[0041] External chassis and base design:

[0042] The outer chassis 1 is designed to be mounted on a base 4, and is fixed specifically by means of a mounting slot 5 provided on the top surface of the base.

[0043] A shock-absorbing pad 6 is arranged inside the base 4 to support the bottom surface of the chassis 1 outside the power distribution cabinet to reduce vibration and improve overall stability.

[0044] A side positioning plate 7 is designed on the top of the mounting slot 5, which fits with the two sides of the bottom of the outer chassis 1 of the power distribution cabinet to enhance the positioning effect, increase stability, and avoid vibration and noise.

[0045] Noise Reduction Design:

[0046] Noise reduction chambers 2 are arranged on the upper, lower, left, right and rear sides of the outer chassis 1 of the power distribution cabinet. A noise reduction core 3 is installed in each noise reduction chamber, covering all directions of the power distribution box to form a full range of noise reduction protection. Through this design, the noise can be effectively reduced no matter which direction it comes from.

[0047] The noise reduction core 3 comprises a multi-layer structure, which comprises, from the inside to the outside, a first noise reduction layer 31 , an inner reinforcement layer 32 , a second noise reduction layer 33 and a flame retardant layer 34 .

[0048] Detailed structure of noise reduction core

[0049] First noise reduction layer 31:
