The protective mechanism includes a buffer assembly, and the main body of the buffer assembly is designed as a slider structure with a damper, and two buffer assemblies are respectively hinged at the bottom side positions of support rod A and support rod B, and the buffer assembly is slidably connected to the inner side position of the side panel.

[0012] Furthermore, the noise isolation mechanism comprises:

[0013] Noise isolation component A, the main body of the noise isolation component A is designed with a rock plate structure, and the interior of the noise isolation component A is also provided with tapered holes with thin left and thick right in a rectangular array, and the noise isolation component A is arranged in a linear array;

[0014] Furthermore, the protection mechanism includes:

[0015] Support rod B, the main body of support rod B is a rectangular parallelepiped structure with a through slot opened inside, and support rod B is hinged at the bottom end surface of the side plate and sleeved at the outer side of support rod A;

[0016] Furthermore, the bearing mechanism comprises:

[0017] Keel: The main body of the keel is designed as an H-shaped structure, and a guide groove is provided on the inner side of the keel;

[0018] Furthermore, the towing mechanism includes:

[0019] Mounting assembly: the main body of the mounting assembly is designed in a Z-shaped structure, and the mounting assembly is installed in a linear array at the front end of the side plate. A protective mechanism is also provided on the lower side of the mounting assembly;

[0020] Furthermore, the noise isolation mechanism comprises:

[0021] Noise isolation component B, the main body of the noise isolation component B is designed with a flame-retardant sponge structure, and the interior of the noise isolation component B is also provided with polygonal honeycomb holes in a rectangular array, and the noise isolation component B is located on the inner side of the noise isolation component A, and a towing mechanism is also provided on the inner side of the noise isolation component B;

[0022] Furthermore, the towing mechanism includes:

[0023] Side panels: The main body of the side panels is a telescopic panel structure design, and the side panels are composed of a solid panel and a hollow panel plug-in;

[0024] Furthermore, the bearing mechanism comprises:

[0025] The main body of the shield is designed as a folding baffle structure, and the shield is installed on the inner side of the keel. A noise isolation mechanism is also provided on the inner side of the shield;

[0026] Furthermore, the protection mechanism includes:

[0027] Support rod A, the main body of support rod A is designed as a rectangular parallelepiped structure, and support rod A is hinged at the bottom end surface of the side plate;

[0028] Furthermore, the noise isolation mechanism comprises:

[0029] The frame body is hingedly connected by two split U-shaped brackets, and one corner of the frame body is slidably connected to the inner side of the keel. An X-shaped bracket is also installed along the diagonal line on the inner side of the frame body.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. In the present invention, an X-shaped bracket is also installed inside the frame of the noise isolation mechanism, which divides the internal space of the frame into four parts. Since it is arranged along the diagonal line of the inside of the frame, it can effectively support the frame. Inside the frame, noise isolation components A and noise isolation components B made of rock slabs are arranged in a linear array. The interior of the noise isolation component A is also provided with tapered holes that are thin on the left and thick on the right in a rectangular array, with the side with a smaller diameter facing the outside of the cabinet.

The main body of the shield is a folding baffle structure design. Under normal conditions, it covers most of the missing groove part of the keel. Moreover, since its cross-section is a wavy structure design, it can not only eliminate the noise generated when the transformer is working, but also utilize the soft nature of the shield to ensure that it has high toughness. Even in the event of severe deformation, it will not cause secondary damage to the components in the cabinet, thereby ensuring the safety of the components in the cabinet.

[0033] 3. In the present invention, since the frame is designed as a split structure, and one corner of the frame is slidably connected to the guide groove opened inside the keel, when the keel is pressed and moves downward, the frame can be bent and then unfolded outward. This operation can not only protect the keel from being compressed, but also use the extra space formed by bending the frame outward to protect the transformer element, so as to achieve a more practical purpose.

[0034] 4. In the present invention, the transformer element can be placed on a mounting assembly of a Z-shaped structure installed on the front side of a solid plate in a side panel in the towing mechanism, and the solid plate side of the side panel is connected to the main body of the keel located on the upper side, so that when the keel moves downward, the transformer element installed on the mounting assembly can be driven to move downward synchronously, thereby avoiding the impact operation after the keel is compressed.

[0035] 5. A protective mechanism is also installed on the inner side of the side panel, in which support rod A and support rod B are hinged at the bottom end surface of the side panel and cross-arranged with each other. When the side panel moves downward, it will push support rod A and support rod B downward and slide outward to release force at the same time. Buffer components are hinged on the outside of support rod A and support rod B. When support rod A and support rod B are under pressure, the damper will stop the vibration and slow down the rebound speed at the same time, so as to avoid the problem of damage to the transformer element due to strong resonance.

Under normal conditions, it covers most of the missing groove part of the keel 101. Moreover, since its cross-section is designed as a wavy structure, it can not only eliminate the noise generated when the transformer is working, but also utilize the soft nature of the shield 102 to ensure that it has high toughness. Even when a severe deformation occurs, it will not cause secondary damage to the components in the cabinet, thereby ensuring the safety of the components in the cabinet.

[0054] refer to Figure 1-3The noise isolation mechanism 2 includes: a frame 201, an X-shaped bracket is installed inside the frame 201 in the noise isolation mechanism 2, which divides the internal space of the frame 201 into four parts, and because it is arranged along the diagonal line inside the frame 201, it can effectively support the frame 201, and the noise isolation components A202 and noise isolation components B203 made of rock plates are arranged in a linear array inside the frame 201, and the interior of the noise isolation component A202 is also provided with tapered holes with thin left and thick right in a rectangular array, and the side with a smaller diameter faces The outside of the cabinet, and the matching noise isolation component B203 has polygonal honeycomb holes in a rectangular array inside, so when the noise isolation component A202 and the noise isolation component B203 form a match, not only can the components inside the keel 101 be effectively protected, but also the flame retardant sponge can be used to both isolate noise and ensure good heat dissipation to assist in heat dissipation. The main body of the frame 201 is formed by hinged two split U-shaped brackets, and one corner of the frame 201 is slidably connected to the inner side of the keel 101. An X-shaped bracket is also installed along the diagonal on the side. The noise isolation mechanism 2 includes: a noise isolation component A202. The main body of the noise isolation component A202 is a rock plate structure design. Since the frame 201 is a split structure design, and one corner of the frame 201 is slidably connected to the guide groove opened inside the keel 101, when the keel 101 is pressed and moves downward, the frame 201 can be bent and then expanded outward. This operation can not only protect the keel 101 from being pressed, but also use the extra space formed by the frame 201 being bent outward to The transformer element is protected to achieve a more practical purpose, and the interior of the noise isolation component A202 is also provided with tapered holes that are thin on the left and thick on the right in a rectangular array, and the noise isolation component A202 is arranged in a linear array, and the noise isolation mechanism 2 includes: a noise isolation component B203, the main body of the noise isolation component B203 is designed with a flame-retardant sponge structure, and the interior of the noise isolation component B203 is also provided with polygonal honeycomb holes in a rectangular array, and the noise isolation component B203 is located on the inner side of the noise isolation component A202, and a towing mechanism 3 is also arranged on the inner side of the noise isolation component B203.

When the side plate 301 moves downward, it will push the support rod A401 and the support rod B402 downward and slide outward to release force at the same time. Buffer components 403 are hinged on the outer sides of the support rods A401 and B402, and then when the support rods A401 and B402 are compressed, the damper will be used to stop the vibration and slow down the rebound speed at the same time, so as to avoid the problem of damage to the transformer element due to strong resonance. The transformer element can be placed in the towing mechanism 3 and installed in the solid plate in the side plate 301. The front side is installed on the mounting component 302 of the Z-shaped structure, and the solid plate side of the side panel 301 is connected to the main body of the keel 101 located on the upper side, so that when the keel 101 moves downward, it can synchronously drive the transformer element installed on the mounting component 302 to move downward synchronously, thereby realizing the operation of avoiding the impact after the keel 101 is compressed. The main body of the side panel 301 is designed as a telescopic plate structure, and the side panel 301 is composed of a solid plate and a hollow plate plug-in. The towing mechanism 3 includes: a mounting component 302, the main body of the mounting component 302 is designed as a Z-shaped structure, and the mounting component 302 is installed in a linear array on the front end surface of the side panel 301, and a protective mechanism 4 is also provided on the lower side of the mounting component 302.

[0057] When in use: Aiming at the problem that the existing transformer noise isolation cabinet cannot combine firmness and noise reduction, when using this device, since the main body of the keel 101 in the bearing mechanism 1 is designed as an H-shaped structure, it can play a stable protective role for the main components in the cabinet, and the keel 101 can disperse the pressure suffered to reduce the deformation of the cabinet;

[0058] Furthermore, longitudinally extending covers 102 are installed on the inner sides of the through grooves on the left and right sides of the keel 101. The main body of the cover 102 is designed as a folding baffle structure. Under normal circumstances, it covers most of the missing groove part of the keel 101. Moreover, since its cross-section is designed as a wavy structure, it can not only eliminate the noise generated when the transformer is working, but also utilize the soft nature of the cover 102 to ensure that it has high toughness. Even in the event of severe deformation, it will not cause secondary damage to the components in the cabinet, thereby ensuring the safety of the components in the cabinet.

[0059] Second embodiment

[0060] Based on a transformer noise reduction cabinet for intelligent machinery manufacturing provided in the first embodiment, the device reduces the deformation of the cabinet body by means of the H-shaped keel 101 and the cover 102 in the bearing mechanism 1, but in actual application, it is still not satisfactory for the efficient noise isolation and protection operation of the device. In order to solve the above problems, the device also includes a noise isolation mechanism 2, which includes: a frame 201, the main body of the frame 201 is formed by hingedly connecting two split U-shaped brackets, and one corner of the frame 201 is slidably connected to the inner side of the keel 101, and the inner side of the frame 201 is connected to the inner side of the keel 101.

[0061] When in use, an X-shaped bracket is installed inside the frame 201 in the noise isolation mechanism 2, which divides the internal space of the frame 201 into four parts. Since it is arranged along the diagonal line inside the frame 201, it can effectively support the frame 201. Inside the frame 201, noise isolation components A202 and noise isolation components B203 made of rock plates are arranged in a linear array. The interior of the noise isolation component A202 is also provided with tapered holes that are thin on the left and thick on the right in a rectangular array, with the side with a smaller diameter facing the outside of the cabinet. The matching noise isolation component B203 is also provided with polygonal honeycomb holes in a rectangular array. When the noise isolation components A202 and the noise isolation components B203 are matched, not only can the components inside the keel 101 be effectively protected, but also the flame retardant sponge can be used to both isolate noise and ensure good heat dissipation to assist in heat dissipation.

[0062] Since the frame 201 is a split structure design, and one corner of the frame 201 is slidably connected to the guide groove opened inside the keel 101, when the keel 101 is pressed and moves downward, the frame 201 can be bent and then unfolded outward. This operation can not only protect the keel 101 from being pressed, but also use the extra space formed by bending the frame 201 outward to protect the transformer element, so as to achieve a more practical purpose.

[0064] Based on the second embodiment, a transformer noise reduction cabinet for intelligent machinery manufacturing is provided. The device can achieve noise reduction operation and generate additional space for replenishment when under pressure with the help of a noise isolation mechanism 2. However, in actual application, it cannot actively and synchronously avoid components when the device is under pressure, and cannot resist and buffer the deformation of the cabinet. As a result, there will still be problems of damage to transformer components caused by pressure. In order to solve the above problems, the device also provides a towing mechanism 3 and a protective mechanism 4. The towing mechanism 3 includes: a side panel 301, the main body of the side panel 301 is a telescopic panel structure design, and the side panel 301 is composed of a solid panel and a hollow panel plug-in. The towing mechanism 3 includes: a mounting assembly 302, the main body of the mounting assembly 302 is a Z-shaped structure design, and the mounting assembly 302 is in a linear array.

[0065] When in use, the transformer element can be placed on the mounting assembly 302 of the Z-shaped structure installed on the front side of the solid plate in the side plate 301 in the towing mechanism 3, and the solid plate side of the side plate 301 is connected to the main body of the keel 101 located on the upper side, so that when the keel 101 moves downward, the transformer element installed on the mounting assembly 302 can be synchronously driven to move downward synchronously, thereby realizing the operation of avoiding the impact of the keel 101 after being compressed;

[0066] A protective mechanism 4 is also installed on the inner side of the side plate 301, wherein the support rod A401 and the support rod B402 are hinged at the bottom end surface of the side plate 301 and are arranged crosswise with each other. When the side plate 301 moves downward, it will push the support rod A401 and the support rod B402 downward and slide outward to release force at the same time. Buffer components 403 are hinged on the outer sides of the support rods A401 and B402. When the support rods A401 and B402 are compressed, the damper will stop the vibration and slow down the rebound speed at the same time, so as to avoid the problem of damage to the transformer element due to strong resonance.
