According to the understanding of inventor to the elevator industry, even to this day, still none is equipped with sound arrester on contactor in the elevator control cabinet or the relay product both at home and abroad, that is to say that still none can effectively completely cut off the device of contactor or relay noise so far.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art exists, a kind of contactor or relay noise reducing device---sound arrester of being applicable to is provided, be specially adapted to the interior noise insulation equipment of elevator control cabinet to contactor or relay, can effectively reduce adhesive or more than the release noise 10dB (A), also be applicable to the place of the isolated electric equipment noise of various needs simultaneously.
Concrete technical scheme of the present utility model is: a kind of sound arrester, be box structure, and it comprises, a box cover 7, a box lower cover 5 and be that coaming plate 6 constitutes on every side, wherein,
One side of described coaming plate 6 has a fan 8,
Stationary cloth is equipped with Sound-proof material 4 on each inwall of described box,
Stationary cloth is equipped with damping pad 10 in the outside of described box lower cover 5, plays the vibration and noise reducing effect,
Contactor or relay are arranged on the interior box lower cover (5) of box.
Adopt bolt connecting mode to fix between box lower cover 5 and the control cubicle.
Described sound arrester is when contactor that is used for elevator control cabinet or relay sound insulation, both sides are provided with 1 or 2 support 2 above the Sound-proof material 4 on described box lower cover 5, support 2 is fixed on the coaming plate 6 by bolt 3, and contactor or relay pass through screw 1 fixed and arranged on support 2.
The utility model compared with prior art has following good effect:
(1), the utility model aims at contactor or the relay sound insulation designs, and effectively reduces noise.
(2), adopting fan that temperature control is carried out in sound arrester inside handles, has prolonged the useful life of contactor or relay.
(3), utilize box structure and in box each wall cloth put Sound-proof material, constitute a combined type denoising structure, improved soundproof effect greatly.
(4), owing between sound arrester and control cubicle cabinet, increase the damping pad, vibration damping is also avoided technology such as " overhead speaker " effect, the adhesive of contactor or relay can be effectively reduced or more than the release noise 10dB (A), environmental noise can be obviously improved, more effectively vibration and noise reducing.
(5), adopt the support mode to make contactor or relay be in state high up in the air, can directly reduce the strike note between contactor and former rigid support device.
In a word, this device has been realized goal of the invention of the present utility model, fan temperature control, combined type sound-insulating structure, contactor are high up in the air to be avoided direct impact noise, damping glue vibration damping and avoids multiple technologies such as " overhead speaker " effect owing to utilize, reduce the adhesive of contactor or relay effectively or discharge more than the noise 10dB (A), it is applicable to the place that the isolated electric equipment of various needs produces noise, particularly can make the operational environment of elevator control cabinet quieter, filled up the blank of prior art, it is reasonable, simple and compact for structure that product has design science.
