[0006] The technical solution of the utility model is as follows:

[0007] A high-security sound-insulating and noise-reducing power transformer comprises a power transformer body, one end of the power transformer body is provided with a breathable grid, both sides of the power transformer body are provided with long grooves, both sides of the power transformer body are movably provided with baffles for protecting the power transformer body, that is, improving the safety of the power transformer body, both sides of the long groove inner walls are movably provided with cooling components for reducing the temperature of core components inside the power transformer body, the inner wall of the power transformer body is slidably connected with a movable protection component for preventing core components from being damaged by impact, and the power transformer body is made of sound-insulating and noise-reducing material.

[0008] Preferably, a first spring and a second spring are fixedly connected to the inner wall of the long slot, the first spring is located above the second spring, and the two are in the same vertical plane, and functional blocks are fixedly connected to both sides of the power transformer body, and the functional blocks are located on both sides of the long slot.

[0009] Preferably, a circular groove is provided on the inner wall of the functional block, round rods are fixedly connected to both sides of the baffle, the round rods are movably arranged inside the circular groove, one end of the first spring is fixedly connected to one side of the baffle, and one end of the second spring is fixedly connected to one side of the baffle.

[0010] Preferably, the cooling component includes a notch extending through the inner wall of the long slot, the notch is connected to the interior of the power transformer body, a filter sheet is fixedly connected to the inner wall of the notch, and a cross-shaped connecting rod is fixedly connected to the inner wall of the notch.

[0011] Preferably, the cross-shaped connecting rod is arranged on the inner side of the filter screen, one end of the cross-shaped connecting rod is fixedly connected to a fixed round block, and one end of the fixed round block is rotatably connected to a rotating shaft.

[0012] Preferably, fan blades are fixedly connected to the outer surface of the rotating shaft, a motor is arranged inside the fixed round block, and one end of the rotating shaft is connected to the motor.

[0013] Preferably, the movable protection component comprises a T-shaped slot formed on the inner wall of the power transformer body, a T-shaped block is movably connected to the inner wall of the T-shaped slot, and third springs are fixedly connected to both sides of the T-shaped block.

[0014] Preferably, one end of the third spring is fixedly connected to the inner wall of the power transformer body, and the upper end of the T-block is fixedly connected to a core component.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, when a foreign object hits the upper side of the baffle, the upper end of the baffle will move toward the inner wall side close to the long groove, and the lower end of the baffle will move away from the inner wall side of the long groove, that is, the baffle is in an inclined state, and the baffle will offset the external force received by the impact, thereby reducing the impact force received by the power transformer body itself, and the impact object will slide along the inclined baffle to the bottom of the power transformer body to unload the impact force. When the foreign object hits the lower side of the baffle, the baffle swings in the opposite direction to unload the force. After there is no impact object on one side of the baffle, under the action of the first spring and the second spring, the first spring and the second spring will drive the baffle to the initial state, that is, the baffle is in a vertical state again, thereby solving the problem of inconvenience in improving the safety of the power transformer.

[0017] 2. The utility model drives the shaft and the fan blades to rotate through a motor. As the shaft and the fan blades rotate, the fan blades will generate a wind force toward the inside of the power transformer body. This wind force will blow the heat inside the power transformer body to the outside along another group of notches and breathable grids, thereby quickly taking the heat inside the power transformer body out of the inside of the power transformer body, thereby achieving the effect of cooling the core components.

[0018] 3. The utility model transmits external force to the inside of the power transformer body, and the T-block inside the power transformer body has a tendency to swing left and right due to the effect of inertia. Due to the existence of the T-slot, the T-block will swing left and right along the T-slot due to the effect of inertia. Since there are third springs on both sides of the T-block, and the third springs are fixedly connected to the inner wall of the power transformer body, the T-block cannot swing significantly along the T-slot. The two groups of third springs will offset the inertia of the T-block, thereby reducing the impact force of the T-block on the external force. Since the core component is fixed at the upper end of the T-block, the impact force of the T-block on the external force is weakened, that is, the impact force of the core component on the external force is weakened, thereby further improving the safety of the power transformer.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] like Figure 1 and Figure 2 As shown, this embodiment proposes a high-security sound-insulating and noise-reducing power transformer, comprising a power transformer body 1, one end of the power transformer body 1 is provided with a breathable grid 2, long grooves 11 are opened on both sides of the power transformer body 1, baffles 3 for protecting the power transformer body 1, that is, improving the safety of the power transformer body 1 are movably provided on both sides of the power transformer body 1, cooling components 4 for reducing the temperature of the core component 54 inside the power transformer body 1 are movably provided on the inner walls of both sides of the long groove 11, a movable protection component 5 for preventing the core component 54 from being damaged by impact is slidably connected to the inner wall of the power transformer body 1, and the power transformer body 1 is composed of sound-insulating and noise-reducing materials.

[0028] like Figure 2 As shown, a filter sheet 42 is fixedly connected to the inner wall of the notch 41 , and the filter sheet 42 is used to prevent foreign matter from entering the interior of the power transformer body 1 through the notch 41 .

[0029] like Figure 3As shown, a first spring 12 and a second spring 13 are fixedly connected to the inner wall of the long slot 11, the first spring 12 is located above the second spring 13, and the two are in the same vertical plane, both sides of the power transformer body 1 are fixedly connected with functional blocks 14, the functional blocks 14 are located on both sides of the long slot 11, and a circular groove 15 is provided on the inner wall of the functional block 14, one end of the first spring 12 is fixedly connected to one side of the baffle 3, and one end of the second spring 13 is fixedly connected to one side of the baffle 3, the cooling component 4 includes a notch 41 that penetrates and is opened on the inner wall of the long slot 11, the notch 41 is connected to the inside of the power transformer body 1, and a cross-shaped connecting rod 43 is fixedly connected to the inner wall of the notch 41, and the cross-shaped connecting rod 43 is arranged on the inner side of the filter screen 42. One end of the U-shaped connecting rod 43 is fixedly connected to a fixed round block 44, one end of the fixed round block 44 is rotatably connected to a rotating shaft 45, and a fan blade 46 is fixedly connected to the outer surface of the rotating shaft 45. A motor is arranged inside the fixed round block 44, and one end of the rotating shaft 45 is connected to the motor. The mobile protection component 5 includes a T-slot 51 opened on the inner wall of the power transformer body 1, and the motor is used to drive the rotating shaft 45 and the fan blade 46 to rotate. The rotation of the rotating shaft 45 and the fan blade 46 is used to cool the core component 54 inside the power transformer body 1. The two groups of notches 41 allow the airflow inside the power transformer body 1 to circulate, that is, the heat inside the power transformer body 1 can be discharged to the outside through the airflow to the notches 41, thereby reducing the temperature of the core component 54 inside the power transformer body 1.

[0030] like Figure 4 As shown, round rods 31 are fixedly connected to both sides of the baffle 3. The round rods 31 are movably arranged inside the circular groove 15. The existence of the round rods 31 facilitates the rotation inside the circular groove 15, so that the baffle 3 can swing on one side of the long groove 11.

[0031] like Figure 5 As shown, a T-block 52 is movably connected to the inner wall of the T-slot 51, and third springs 53 are fixedly connected to both sides of the T-block 52. One end of the third spring 53 is fixedly connected to the inner wall of the power transformer body 1, and a core component 54 is fixedly connected to the upper end of the T-block 52. The third spring 53 is used to limit the T-block 52 so that the T-block 52 will not slide freely along the T-slot 51.

[0032] The working principle and use instructions of the utility model are as follows: Because the power transformer body 1 is made of sound insulation and noise reduction materials, the device as a whole can form an effective sound insulation and noise reduction effect. When it is necessary to cool the core component 54 inside the power transformer body 1, the staff first needs to control the motor to start, so that the motor drives the shaft 45 and the fan blades 46 to rotate. As the shaft 45 and the fan blades 46 rotate, the fan blades 46 will generate a wind force inside the power transformer body 1. This wind force will blow the heat inside the power transformer body 1 along another group of notches 41 and the breathable grid 2 to the outside, so as to quickly dissipate the heat inside the power transformer body 1. The outer wall of the power transformer body 1 is brought out of the inner wall of the power transformer body 1, so as to achieve the effect of cooling the core component 54. When one side of the power transformer body 1 is hit, when the foreign object hits the upper side of the baffle 3, due to the existence of the round rod 31 and the round groove 15, the upper end of the baffle 3 will move toward the inner wall side close to the long groove 11. At this time, the lower end of the baffle 3 will be away from the inner wall side of the long groove 11, that is, the baffle 3 is in an inclined state. At this time, the baffle 3 will offset the external force received by the impact, thereby reducing the impact force received by the power transformer body 1 itself, thereby forming a certain protection for the power transformer body 1, thereby enhancing the safety of the power transformer body 1, and because the baffle 3 is in an inclined state, its impact When the object hits the lower side of the baffle 3, the baffle 3 swings in the opposite direction to release the force. After there is no impact on one side of the baffle 3, the first spring 12 and the second spring 13 drive the baffle 3 to the initial state, that is, the baffle 3 is in the vertical state again. When the power transformer body 1 is hit by an external force, the external force is transmitted to the inside of the power transformer body 1. The T-block 52 inside the power transformer body 1 has a tendency to swing left and right due to the inertia. Due to the existence of the T-slot 51, the T-block 5 The T-shaped block 52 can swing left and right along the T-shaped slot 51 due to the inertia, but because there are third springs 53 on both sides of the T-shaped block 52, and the third springs 53 are fixedly connected to the inner wall of the power transformer body 1, the T-shaped block 52 cannot swing greatly along the T-shaped slot 51, and the two groups of third springs 53 can offset the inertia of the T-shaped block 52, thereby further reducing the impact force of the T-shaped block 52 subjected to external force, and because the core component 54 is fixed at the upper end of the T-shaped block 52, the impact force of the T-shaped block 52 subjected to external force is weakened, that is, the impact force of the core component 54 subjected to external force is weakened, thereby further improving the safety of the power transformer.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
