[0033] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 3 , Figure 7As shown, the utility model is a noise reduction and sound insulation device for a main transformer room of a transformer substation, comprising a main transformer room body 1, both sides of the inner wall of the main transformer room body 1 are provided with card slots 2, the inner wall of the card slot 2 is provided with an exhaust assembly 3, both side surfaces of the main transformer room body 1 are fixedly connected with a ventilation box 4, the outer surface of the ventilation box 4 is provided with a driving device 5, the output end of the driving device 5 is provided with a sound absorbing assembly 6, the top of the main transformer room body 1 is provided with a ventilation groove 7, the top of the main transformer room body 1 is provided with a sound insulation assembly 8, the interior of the main transformer room body 1 is slidably connected with a flow guide mechanism 9, and the outer surface of the main transformer room body 1 is hinged with a sealing door 10.

[0036] When in use, two groups of ventilation boxes 4 are fixed on both sides of the main transformer chamber body 1. When the inside of the main transformer chamber body 1 needs to be ventilated, the exhaust component 3 is started to operate and the external air is sucked and circulated to the inside of the ventilation box 4. At the same time, the driving device 5 is started to operate to drive the two groups of sound insulation components 8 to operate inside the ventilation box 4, so that the air entering through the outside of the ventilation box 4 passes through the gap of the sound insulation component 8 and is then sucked into the inside of the main transformer chamber body 1 through the exhaust component 3. At the same time, when the air inside the main transformer chamber body 1 flows upward for ventilation, the radial flow guide mechanism 9 diverts it and then circulates it to the ventilation groove 7 for discharge.

[0037] The utility model arranges the exhaust end of the exhaust component 3 inside the ventilation box 4. When the exhaust is carried out inside the main transformer chamber body 1, the air flow passes through the ventilation box 4 to the inside, and then cooperates with the driving device 5 to drive the sound absorbing component 6 to rotate, so that the air flow passes through the gap and can absorb the noise generated when the air flow is sucked in. At the same time, the sound absorbing component 6 rotates and drives the air flow to increase the rate of its circulation to the inside of the main transformer chamber body 1. The guide mechanism 9 guides the air circulating during ventilation inside and cooperates with the sound insulation component 8 to make the hot air flow have the function of noise blocking and discharging when the ventilation is discharged. In this way, the main transformer chamber body 1 can be ventilated and the noise emitted from the inside of the main transformer chamber body 1 can be reduced and blocked to avoid noise pollution.

[0038] In one embodiment, for the above-mentioned card slot 2, there are several card slots 2 and exhaust components 3, the exhaust components 3 are all located inside the ventilation box 4, and there are several ventilation slots 7.

[0039] Through the cooperation of several card slots 2 and exhaust components 3, multiple sets of ventilation channels can be formed inside the main transformer chamber body 1, and the efficiency of heat dissipation inside the main transformer chamber body 1 can be accelerated in conjunction with the ventilation slots 7.

[0040] In one embodiment, for the ventilation box 4 mentioned above, the ventilation box 4 includes a bellows 401 , an outer surface of the bellows 401 is provided with an air inlet groove 402 , an interior of the bellows 401 is provided with a flow cavity 403 , and the sound absorbing component 6 is located inside the flow cavity 403 .

[0041] There are multiple air inlet grooves 402 evenly distributed on the outer surface of the bellows 401. When the exhaust component 3 is started, the sucked air passes through the air inlet grooves 402 and enters the interior of the circulation cavity 403. At the same time, the rotation of the sound absorbing component 6 allows the airflow to enter the interior of the main transformer chamber body 1 after sound absorption treatment by the sound absorbing component 6.

[0042] In one embodiment, for the above-mentioned driving device 5, the driving device 5 includes a motor 501, and the output end of the motor 501 is provided with a driving shaft 502, the output end of the driving shaft 502 is fixedly connected with a driving wheel 503, the outer surface of the driving wheel 503 is transmission-connected with a driving belt 504, one end of the driving wheel 503 is fixedly connected with a main shaft 505, and the main shaft 505 is fixedly connected to one end of the sound absorbing component 6.

[0043] By starting the driving motor 501 to drive the driving shaft 502 to rotate, the driving shaft 502 drives the driving wheel 503 and the main shaft 505 to rotate, and at the same time cooperates with the transmission belt 504 to drive another set of driving wheels 503 to rotate, thereby providing rotational driving force for the two sets of sound absorbing components 6, so that the upper and lower sets of sound absorbing components 6 can cooperate to provide airflow sound absorption and diversion effects for the two sets of exhaust components 3 at the same time.

[0044] In one embodiment, for the above-mentioned sound absorbing component 6, the sound absorbing component 6 includes a fixing rod 601, and a sound absorbing panel 602 is fixedly connected to the outer surface of the fixing rod 601. There are several sound absorbing panels 602, and the several sound absorbing panels 602 are evenly distributed on the outer surface of the fixing rod 601.

[0045] When the driving wheel 503 drives the main shaft 505 to rotate, the fixing rod 601 is driven to rotate by the main shaft 505, and at the same time drives the multiple groups of sound absorbing panels 602 obliquely arranged outside the fixing rod 601 to rotate.

[0046] When the fixing rod 601 is driven to rotate by the main shaft 505, the sound absorbing plate 602 continues to rotate. After the air is sucked into the circulation cavity 403 by the exhaust assembly 3, the air flow is driven by the sound absorbing plate 602 to swirl and pass through its gap, so that the air flow is separated and passes through the inner wall of the sound absorbing plate 602. In this way, the sound absorbing plate 602 can attract and reduce the noise of the air flow when it passes through, thereby reducing the noise generated when the main transformer chamber body 1 is ventilated.

[0047] In one embodiment, for the above-mentioned exhaust assembly 3, the exhaust assembly 3 includes a fan cover 301, and an exhaust fan 302 is arranged inside the fan cover 301. The exhaust fan 302 extends to the inside of the main transformer chamber body 1.

[0048] By clamping the fan cover 301 on the inner wall of the slot 2, the exhaust fan 302 is supported between the inner wall of the main transformer chamber body 1 and the bellows 401. When the exhaust fan 302 is started, a suction force is generated inside the fan cover 301 to draw the air outside the bellows 401 into the main transformer chamber body 1 for ventilation.

[0049] In one embodiment, for the above-mentioned guide mechanism 9, the guide mechanism 9 includes a horizontal slide plate 901, and the outer surface of the horizontal slide plate 901 is provided with a plurality of sound insulation plates 902. The inner wall of the main transformer chamber body 1 is fixedly connected with a guide plate 12, and the horizontal slide plate 901 is slidably connected to the outer surface of the guide plate 12.

[0050] By slidingly connecting the horizontal sliding plate 901 to the outside of the guide plate 12, air flow is continuously introduced into the main transformer chamber body 1 for ventilation. The air flow is blocked and diverted by the sound insulation board 902 upstream, and flows out through the inner wall of the sound insulation board 902. The sound insulation boards 902 are stacked layer by layer to soundproof the air flow when it passes through, thereby reducing the noise generated inside the main transformer chamber body 1.

[0051] In one embodiment, for the above-mentioned sound insulation component 8, the sound insulation component 8 includes a sound insulation cover 801, and the inner wall of the sound insulation cover 801 is fixedly connected with a support rod 802.

[0052] The soundproof cover 801 is supported on the top of the main transformer chamber body 1 by the support rod 802 , so as to block the noise on the top of the main transformer chamber body 1 .

[0053] In one embodiment, for the above-mentioned support rods 802, there are four groups of support rods 802, wherein the bottoms of three groups of support rods 802 are fixedly connected with support springs 803, the bottoms of the support springs 803 are fixedly connected with support seats 804, and the outer surface of one group of support rods 802 is provided with a rack 805, and one side of the rack 805 is meshed with a lifting gear 806.

[0054] Through the cooperation of the lifting gear 806 and the rack 805, when necessary, the lifting gear 806 can be rotated to drive the rack 805 to drive the support rod 802 to rise and fall. At the same time, the other three groups of support rods 802 supported by support springs 803 at the bottom can cooperate with the elastic support of the support springs 803 and rise and fall together with the rack 805.

[0055] By arranging a rack 805 and a lifting gear 806 on the outside of one set of support rods 802, the height of the top sound insulation cover 801 can be adjusted, so that the sound insulation cover 801 can be close to the ventilation groove 7 or away from the top of the ventilation groove 7, thereby enabling the sound insulation cover 801 to have an effective sound insulation effect at its top.

[0056] In one embodiment, for the above-mentioned sound insulation cover 801, the sound insulation cover 801 is trapezoidal, and the inner wall of the sound insulation cover 801 is provided with a sound absorbing layer.

[0057] By providing a sound-absorbing layer on the inner wall of the soundproof cover 801 and simultaneously covering the top of the ventilation groove 7 with the soundproof cover 801, a better sound insulation and noise reduction effect can be achieved, thereby reducing the noise pollution emitted by the main transformer room body 1 when in use.

[0058] Through the above technical scheme, 1. By arranging the exhaust end of the exhaust component 3 inside the ventilation box 4, when it exhausts the inside of the main transformer chamber body 1, the air flow passes through the ventilation box 4 to the inside, and cooperates with the driving device 5 to drive the sound absorbing component 6 to rotate, so that the air flow passes through its gap and can absorb the noise generated when the air flow is sucked in. At the same time, the sound absorbing component 6 rotates and drives the air flow to increase its circulation rate to the inside of the main transformer chamber body 1. The guide mechanism 9 guides the air circulating during ventilation inside and cooperates with the sound insulation component 8 so that the hot air flow can play a role in noise blocking and discharging when the ventilation is discharged. In this way, the main transformer chamber body 1 can be ventilated and the noise emitted from the inside of the main transformer chamber body 1 can be reduced and blocked to avoid noise pollution. ; 2. When the fixed rod 601 is driven by the main shaft 505 to rotate, the sound absorbing plate 602 continues to rotate. After the air is sucked into the circulation cavity 403 by the exhaust component 3, the air flow is driven by the sound absorbing plate 602 to swirl and pass through its gap, so that the air flow is separated and passes through the inner wall of the sound absorbing plate 602, so that the sound absorbing plate 602 can attract and reduce the noise of the air flow when it passes through, thereby reducing the noise generated during ventilation of the main transformer chamber body 1; by arranging a rack 805 and a lifting gear 806 on the outside of one set of support rods 802, the top sound insulation cover 801 can be height-adjusted, so that the sound insulation cover 801 can be close to the ventilation groove 7 or away from the top of the ventilation groove 7, so that the sound insulation cover 801 can have an effective sound insulation effect at its top.
