Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-9, the present invention provides a technical solution: a movable noise reduction box-type substation comprises a box-type substation shell 1, wherein a placing plate 2 is arranged in the box-type substation shell 1, through holes 3 are formed in corners of the placing plate 2, vertical rods 4 penetrate through the through holes 3, a buffer cushion 5 is screwed at the bottom ends of the vertical rods 4, the buffer cushion 5 is made of rubber and has good buffer performance, the bottom end of the buffer cushion 5 is screwed at the bottom end of the inner wall of the box-type substation shell 1, and a vibration isolation spring 6 is sleeved on each vertical rod 4;

the bottom of the vertical rod 4 is of a T-shaped structure, two ends of the vibration isolation spring 6 are respectively welded to the bottom end face of the placing plate 2 and the vertical rod 4, and the vibration isolation spring 6 effectively buffers and absorbs energy to the vibration force applied to the placing plate 2;

the vibration isolation device is characterized in that the upper end of the placing plate 2 is in threaded connection with a vibration isolation pad 7, the vibration isolation pad 7 is made of rubber and has good vibration isolation performance, the vibration isolation pad 7 is located in the middle of the upper end face of the placing plate 2, the upper end of the vibration isolation pad 7 is in threaded connection with a transformer, and the vibration isolation pad 7 buffers vibration of the transformer in operation;

4 lateral wall two sides of montant all are equipped with draw-off opening 8, and the smooth joint has slider 9 in the draw-off opening 8, it has sound absorbing plate group 10 to bond again or the spiro union between montant 4, sound absorbing plate group 10 comprises two abatvoix, and the abatvoix material is the pottery aluminium fire prevention abatvoix, and sound absorbing hole staggered arrangement between two abatvoix, and sound wave class noise that sound absorbing plate group 10 produced the transformer carries out preliminary energy-absorbing and falls and fall and make an uproar, and the noise of making an uproar falls again through the board of making an uproar that falls on the noise process of making an uproar again on 1 inner wall of box-type substation shell, has better noise reduction, and equal spiro union has both ears piece 11 again or bond on sound absorbing plate group 10 both sides wall, insert in both ears piece 11 slider 9 outer end, and be provided with between slider 9 and both ears piece 11 and push away the subassembly.

The pushing assembly comprises push rods 12 symmetrically welded on the outer wall of a sliding block 9, fixed blocks 13 are welded on two end faces of a double-lug block 11, a movable hole 14 is formed in the side wall of each fixed block 13, the push rods 12 penetrate through the movable holes 14, a reset spring 15 is sleeved at the extending end of each push rod 12, the reset spring 15 is in a stretching state, the reset spring 15 generates outward thrust on the push rods 12, and further the sliding block 9 is inserted into a sliding opening 8, the sliding block 9 is conveniently moved out of the sliding opening 8 due to the arrangement, and therefore the sound-absorbing plate group 10 is conveniently mounted and dismounted, a lifting groove 16 is formed in the front of the double-lug block 11, and the lifting groove 16 is convenient for inserting fingers into the lifting groove, so that the double-lug block 11 is vertically lifted.

The working principle of the embodiment is as follows: when the noise reduction treatment is carried out on the transformer in the box-type substation shell 1, after the transformer is installed on the vibration isolation pad 7 on the placing plate 2, an operator needs to hold the sliders 9 on two sides of the sound absorbing plate group 10 to move towards the notch ends in the double-lug blocks 11 after sliding the sliders 9 on two sides into the sliding openings 8 on the vertical rods 4, then the sliders 9 are moved to the sliding openings 8 on the corresponding surfaces of the two vertical rods 4, the hands holding the sliders 9 are released, the sliders 9 are inserted into the sliding openings 8 under the action of the reset springs 15 on the push rods 12, so that the installation of the sound absorbing plate group 10 is completed, the subsequent installation and disassembly of the sound absorbing plate group 10 are facilitated, when the transformer needs to be maintained, only the hands are required to extend into the lifting grooves 16 on the double-lug blocks 11, the sliders 9 on two sides need to be additionally moved out from the sliding openings 9, and then the sound absorbing plate group 10 is disassembled through the lifting grooves 16, in-process at daily use, the vibration that the transformer produced is carried out preliminary buffering by vibration isolator 7, later be located 6 and the blotter 5 of vibration isolation spring on montant 4 and carry out the secondary buffering to the vibration, thereby carry out effectual weakening to vibration noise, and the acoustic panel group 10 that is located the transformer four sides weakens the sound wave noise that the transformer produced, it makes an uproar to cooperate the board of making an uproar of falling on the 1 inner wall of box-type substation shell again and carries out the secondary and falls, thereby carry out effectual noise reduction to the transformer in the box-type substation shell 1 and handle.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
