Although it has better noise reduction effect than the single-layer noise reduction structure, the overall equipment cost is relatively high, and the multi-layer sound insulation structure will occupy more space in the cabinet, affecting the installation of other electronic components and the use effect is not good. In order to solve the above problems, an electrical cabinet with a noise reduction air duct is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the current noise reduction electrical cabinets can achieve a certain noise reduction effect, but generally speaking, the noise reduction effect is improved by stacking multiple layers of sound insulation and noise reduction structures. Although it has a better noise reduction effect than a single-layer noise reduction structure, the overall equipment cost is relatively high, and the multi-layer sound insulation structure will occupy more space in the cabinet, affecting the installation of other electronic components and the problem of poor use effect. An electrical cabinet with a noise reduction air duct is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an electrical cabinet with a noise reduction air duct, comprising a cabinet body, a top shell is fixedly installed on the top of the cabinet body, a driving motor is fixedly installed on the top surface of the top shell, an installation groove is provided on the inner surface of the cabinet body, a sound-absorbing inner pad is fixedly installed in the installation groove, a cabinet door is installed on the outside of the cabinet body through a hinge, a reciprocating screw is fixedly installed on one end of the output shaft of the driving motor, a built-in heat dissipation component is installed on the external thread of the reciprocating screw, and the built-in heat dissipation component is used for mobile heat dissipation in the cabinet body, an air guide mechanism is fixedly installed on the inner wall of the cabinet body through a mounting frame, the air guide mechanism is used for accelerating and conducting airflow, and a sound wave conduction component is rotatably installed on the inner wall of the cabinet body above the air guide mechanism, and the sound wave conduction component is used for conducting noise sound waves in the cabinet body.

[0006] As a further description of the above technical solution: The built-in heat dissipation component comprises a movable screw sleeve, the movable screw sleeve is threadedly mounted on the reciprocating screw, and a threaded barrel is rotatably mounted on the top end of the movable screw sleeve through a rib.

[0007] As a further description of the above technical solution: The threaded barrel is threadably connected to the reciprocating screw via a threaded hole arranged inside the threaded barrel, an inclined fan blade is fixedly installed on the outside of the threaded barrel, threaded columns are fixedly installed on the outer walls of both sides of the movable screw sleeve via connecting rods, a heat dissipation groove is arranged on the outer wall of one side of the cabinet, and a heat dissipation net is embedded in the heat dissipation groove.

[0008] As a further description of the above technical solution: The air guide mechanism includes an air duct tube, a mounting sleeve is fixedly installed inside the air duct tube, a threaded sleeve is rotatably installed inside the mounting sleeve, an air fan is fixedly installed on one side outer wall of the threaded sleeve, the threaded column is located directly below the threaded sleeve, and the threaded column and the threaded hole arranged inside the threaded sleeve are adapted to each other.

[0009] As a further description of the above technical solution: An air outlet assembly is arranged at the top of the air duct cylinder, and the air outlet assembly comprises a mounting shell, an air outlet pipe is fixedly mounted on the top surface of the mounting shell, and an air inlet pipe is fixedly mounted on the bottom surface of the mounting shell.

[0011] As a further description of the above technical solution: The sound wave conduction component includes a mounting shaft, which is rotatably mounted on the inner wall of the cabinet, and a torsion spring and a sound waveguide plate are fixedly mounted on the outside of the mounting shaft, one end of the torsion spring is fixedly connected to one side inner wall of the cabinet, and a plurality of sound waveguide grooves are arranged on the bottom surface of the sound waveguide plate.

[0012] Furthermore, by matching the sound wave conduction component and the built-in heat dissipation component, when the electrical cabinet is working, the drive motor can be automatically turned on, the drive motor can drive the reciprocating screw to rotate, and the reciprocating screw can drive the built-in heat dissipation component to reciprocate up and down. When the built-in heat dissipation component is displaced, since the threaded cylinder is threadedly connected to the reciprocating screw through the threaded hole arranged inside it, the threaded cylinder and the inclined fan blades can rotate to generate airflow, disturb the heat in the electrical cabinet, and make the hot air flow quickly discharged through the heat dissipation net. At the same time, the airflow in the equipment can also blow the sound wave conduction component. At this time, the sound waveguide plate can be deflected under the action of the installation shaft. When the sound waveguide plate is deflected, the noise generated in the equipment The sound waves can continuously contact the sound waveguide plate, and thus be dispersed and conducted to other positions in the equipment by several sound waveguide grooves. A sound-absorbing inner pad is arranged in the equipment, which can effectively absorb the dispersed weak noise, thereby achieving a good noise reduction effect of the equipment. Through this design, not only can the mobile heat dissipation effect in the equipment be achieved, and the long-term working effect of the electrical cabinet be improved, but also the sound wave conduction component can be freely deflected by the airflow to achieve effective scattering of the sound waves, thereby improving the adsorption effect of the sound-absorbing inner pad on noise, and can also effectively avoid noise concentration, abandon the method of controlling noise by superimposing multiple layers of noise reduction materials, and can also effectively control the equipment manufacturing cost and provide more installation space for electronic components.

[0014] As a further description of the above technical solution: The other two ends of the T-shaped mounting frame are rotatably mounted with flattening rollers, and the flattening rollers are in close contact with and squeeze the sound-absorbing inner pad.

[0015] As a further description of the above technical solution: A wiring assembly is fixedly installed on the rear outer wall of the cabinet, and the wiring assembly is used for quick connection of data lines. The wiring assembly includes a connector, a wire connection port is arranged on the top surface of the connector, and a socket is arranged on one side outer wall of the connector.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a sound wave conduction component and a built-in heat dissipation component are installed in a matching manner. When the electrical cabinet is working, the driving motor can be automatically turned on, the driving motor can drive the reciprocating screw to rotate, and the reciprocating screw can drive the built-in heat dissipation component to reciprocate up and down. When the built-in heat dissipation component is displaced, since the threaded cylinder is threadedly connected to the reciprocating screw through the threaded hole arranged inside it, the threaded cylinder and the inclined fan blades can rotate to generate airflow, disturb the heat in the electrical cabinet, and make the hot air flow quickly discharged through the heat dissipation net. At the same time, the airflow in the equipment can also blow the sound wave conduction component. At this time, the sound waveguide plate can be deflected under the action of the installation shaft. When the sound waveguide plate is deflected, the noise generated in the equipment The sound waves can continuously contact the sound waveguide plate, and thus be dispersed and conducted to other positions in the equipment by a number of sound waveguide grooves. A sound-absorbing inner pad is arranged in the equipment, which can effectively absorb the dispersed weak noise, thereby achieving a good noise reduction effect of the equipment. Through this design, not only can the mobile heat dissipation effect in the equipment be achieved, and the long-term working effect of the electrical cabinet be improved, but also the sound wave conduction component can be freely deflected by the airflow to achieve effective scattering of the sound waves, thereby improving the adsorption effect of the sound-absorbing inner pad on noise, and can also effectively avoid noise concentration, abandon the method of controlling noise by superimposing multiple layers of noise reduction materials, and can also effectively control the equipment manufacturing cost, and provide more installation space for electronic components.

[0017] 2. In the present invention, an air guide mechanism is provided inside, so that when the built-in heat dissipation component is displaced, the threaded column can be driven to displace synchronously. Since the threaded holes provided inside the threaded column and the threaded sleeve are adapted to each other, the threaded sleeve and the air fan can be driven to rotate synchronously when the threaded column is displaced. The air fan can generate a large amount of airflow in the air duct tube, and the generated airflow can be conducted upward to the air outlet component. After the airflow enters the air outlet component, the airflow acceleration volute can be used to effectively increase the airflow speed. Finally, the airflow can be guided out through the air outlet pipe and blown to the sound wave conduction component. At this time, the sound wave conduction component is subjected to a greater wind force, which greatly increases the deflection angle of the sound wave conduction component, thereby improving the scattering effect of the sound wave conduction component on the sound waves. At the same time, the guided airflow can also cooperate with the built-in heat dissipation component to achieve a better heat dissipation effect, thereby improving the use effect of the equipment.

[0018] 3. In the present invention, a flattening roller is provided on the built-in heat dissipation component. When the built-in heat dissipation component is displaced, the flattening roller can effectively roll the sound-absorbing pad arranged on the inner wall of the cabinet. Due to the external top action of the built-in spring, the flattening roller can generate a certain pressure on the sound-absorbing pad when rolling, and can continuously ensure the flatness of the middle area of ​​the sound-absorbing pad. Through this design, when the built-in heat dissipation component is in use, the flattening roller can continuously roll the sound-absorbing pad in the middle area, which can effectively avoid the situation where the middle area of ​​the sound-absorbing pad and the cabinet are gapped due to being in a high temperature environment for a long time, and can continuously ensure the use effect of the sound-absorbing pad.

[0032] The built-in heat dissipation component 9 includes a movable screw sleeve 98, which is threadedly installed on the reciprocating screw 10. A threaded barrel 91 is installed on the top of the movable screw sleeve 98 through a turning rod. The threaded barrel 91 is threadedly connected to the reciprocating screw 10 through a threaded hole arranged inside the threaded barrel 91. An inclined fan blade 92 is fixedly installed on the outside of the threaded barrel 91. Threaded columns 94 are fixedly installed on the outer walls of both sides of the movable screw sleeve 98 through connecting rods. A heat dissipation groove is arranged on the outer wall of one side of the cabinet 2, and a heat dissipation net 4 is embedded in the heat dissipation groove.

[0033] The sound wave conduction component 7 includes a mounting shaft 73, which is rotatably mounted on the inner wall of the cabinet 2, and a torsion spring 72 and a sound waveguide plate 71 are fixedly mounted on the outside of the mounting shaft 73, one end of the torsion spring 72 is fixedly connected to the inner wall of one side of the cabinet 2, and a plurality of sound waveguide grooves 74 are arranged on the bottom surface of the sound waveguide plate 71.

[0034] The specific implementation method is as follows: when the electrical cabinet is working, the driving motor 1 can be automatically turned on, the driving motor 1 can drive the reciprocating screw 10 to rotate, and the reciprocating screw 10 can drive the built-in heat dissipation component 9 to reciprocate up and down. When the built-in heat dissipation component 9 is displaced, since the threaded cylinder 91 is threadedly connected to the reciprocating screw 10 through the threaded hole arranged inside it, the threaded cylinder 91 and the inclined fan blades 92 can rotate to generate airflow, disturb the heat in the electrical cabinet, and make the hot air flow quickly discharged through the heat dissipation network 4. At the same time, the airflow in the equipment can also blow the sound wave conduction component 7. At this time, the sound waveguide plate 71 can be deflected under the action of the mounting shaft 73. When the sound waveguide plate 71 is deflected, the noise sound waves generated in the equipment can continuously contact the sound waveguide plate 71, thereby being dispersed and conducted to other positions in the equipment by a plurality of sound waveguide grooves 74. A sound-absorbing inner pad 11 is arranged in the equipment, which can effectively absorb the dispersed weak noise, thereby achieving a good noise reduction effect of the equipment.

It can also effectively avoid noise concentration, abandon the method of controlling noise by superimposing multiple layers of noise reduction materials, and effectively control the equipment manufacturing cost, providing more installation space for electronic components.

[0036] The air guide mechanism 8 includes an air duct tube 82, a mounting sleeve 85 is fixedly installed inside the air duct tube 82, a threaded sleeve 83 is rotatably installed inside the mounting sleeve 85, an air fan 84 is fixedly installed on one side outer wall of the threaded sleeve 83, the threaded column 94 is located directly below the threaded sleeve 83, the threaded column 94 and the threaded hole arranged inside the threaded sleeve 83 are adapted to each other, an air outlet component 81 is arranged on the top of the air duct tube 82, the air outlet component 81 includes a mounting shell 814, an air outlet pipe 815 is fixedly installed on the top surface of the mounting shell 814, an air inlet pipe 813 is fixedly installed on the bottom surface of the mounting shell 814, an airflow acceleration volute 812 is fixedly installed inside the mounting shell 814, a side cover 811 is fixedly installed on one side outer wall of the mounting shell 814, and one end of the air inlet pipe 813 is fixedly connected to the air hole arranged on the top surface of the air duct tube 82.

[0037] The specific implementation method is as follows: when the built-in heat dissipation component 9 is displaced, the threaded column 94 can be driven to displace synchronously. Since the threaded column 94 and the threaded holes arranged inside the threaded sleeve 83 are adapted to each other, the threaded sleeve 83 and the air fan 84 can be driven to rotate synchronously when the threaded column 94 is displaced. The air fan 84 can generate a large amount of airflow in the air duct tube 82, and the generated airflow can be conducted upward to the air outlet component 81. After the airflow enters the air outlet component 81, the airflow acceleration volute 812 can be used to effectively increase the airflow speed. Finally, the airflow can be guided out through the air outlet pipe 815 to blow toward the sound wave conduction component 7. At this time, the sound wave conduction component 7 is subjected to a greater wind force, which greatly increases the deflection angle of the sound wave conduction component 7, thereby improving the scattering effect of the sound wave conduction component 7 on the sound waves. At the same time, the guided airflow can also cooperate with the built-in heat dissipation component 9 to achieve a better heat dissipation effect.

A T-shaped mounting bracket 96 is fixedly installed on one end of the internal spring 95. One end of the T-shaped mounting bracket 96 is slidably connected to the inside of the side sleeve 93, and flattening rollers 97 are rotatably installed on the other two ends of the T-shaped mounting bracket 96. The flattening rollers 97 are in close contact and compression with the sound-absorbing inner pad 11.

[0039] A wiring assembly 5 is fixedly installed on the rear outer wall of the cabinet 2. The wiring assembly 5 is used for quick connection of data lines. The wiring assembly 5 includes a connector 51. A wire connection port 52 is provided on the top surface of the connector 51. A socket 53 is provided on one side outer wall of the connector 51.

[0040] The specific implementation method is as follows: when the built-in heat dissipation component 9 is displaced, the flattening roller 97 can effectively roll the sound-absorbing inner pad 11 arranged on the inner wall of the cabinet 2. Due to the external push action of the built-in spring 95, the flattening roller 97 can generate a certain pressure on the sound-absorbing inner pad 11 when rolling, thereby continuously ensuring the flatness of the middle area of ​​the sound-absorbing inner pad 11.

[0041] Through this design, when the built-in heat dissipation component 9 is in use, the flattening roller 97 can continue to perform continuous rolling processing on the sound-absorbing inner pad 11 in the middle area, which can effectively avoid the situation where the middle area of ​​the sound-absorbing inner pad 11 and the cabinet body are gapped due to being in a high temperature environment for a long time, and the use effect of the sound-absorbing inner pad 11 can be continuously guaranteed.

When the built-in heat dissipation component 9 is displaced, since the threaded cylinder 91 is threadedly connected to the reciprocating screw 10 through the threaded holes provided inside, the threaded cylinder 91 and the inclined fan blades 92 can rotate to generate airflow, disturb the heat in the electrical cabinet, and make the hot airflow quickly discharged through the heat dissipation net 4. At the same time, the airflow in the equipment can also The waveguide assembly 7 is blown, and the sound waveguide plate 71 can be deflected under the action of the mounting shaft 73. When the sound waveguide plate 71 is deflected, the noise sound waves generated in the device can continue to contact the sound waveguide plate 71, and thus be dispersed and conducted to other positions in the device by a plurality of sound waveguide grooves 74. A sound-absorbing inner pad 11 is arranged in the device, which can effectively absorb the dispersed weak noise, thereby achieving a good noise reduction effect of the device; when the built-in heat dissipation assembly 9 is displaced, the threaded column 94 can be driven to displace synchronously. Since the threaded column 94 and the threaded sleeve 8 The threaded holes arranged inside the air outlet assembly 81 are adapted to each other, so when the threaded column 94 is displaced, the threaded sleeve 83 and the air fan 84 can be synchronously driven to rotate, and the air fan 84 can generate a large amount of airflow in the air duct cylinder 82, and the generated airflow can be conducted upward to the air outlet assembly 81. After the airflow enters the air outlet assembly 81, the airflow can be effectively accelerated by the airflow acceleration volute 812, and finally the airflow can be guided out through the air outlet pipe 815 to blow toward the sound wave conduction assembly 7. At this time, the sound wave conduction assembly 7 is subjected to a greater wind force, which greatly increases the deflection angle of the sound wave conduction assembly 7, thereby The scattering effect of the sound wave conduction component 7 on sound waves is improved, and the derived airflow can also cooperate with the built-in heat dissipation component 9 to achieve a better heat dissipation effect, thereby improving the use effect of the equipment; when the built-in heat dissipation component 9 is displaced, the flattening roller 97 can effectively roll the sound-absorbing inner pad 11 arranged on the inner wall of the cabinet 2. Due to the external push effect of the built-in spring 95, the flattening roller 97 can generate a certain pressure on the sound-absorbing inner pad 11 when rolling, thereby continuously ensuring the flatness of the middle area of ​​the sound-absorbing inner pad 11, and continuously ensuring the use effect of the sound-absorbing inner pad 11.
