Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a combined protective shell for an outdoor transformer with a noise reduction and current diversion device. The base 100 has sliding grooves on both sides of its top wall. Double-ended screws 101 are rotatably connected to the opposing sidewalls of the two sets of sliding grooves. The double-ended screws 101 facilitate the movement of two sets of movable seats 102 towards or away from each other. Movable seats 102 are screwed to both sides of the outer wall of the double-ended screws 101. The movable seats 102 facilitate the movement of the protective shell 103. The protective shell 103 is rotatably connected to the front and rear sidewalls of the inner cavity of the movable seats 102. The protective shell 103 facilitates assembly to protect the transformer body 105. The left protective shell 103... The right side wall of the protective shell 103 is provided with a snap-fit ​​groove, which facilitates the snap-fit ​​and limiting of the snap-fit ​​bracket 104. The left side wall of the right protective shell 103 is fixedly connected to the snap-fit ​​bracket 104, which facilitates the limiting and fixing of the protective shell 103. The top wall of the base 100 is fixedly connected to the transformer body 105. The transformer body 105 is an electrical device that uses the principle of electromagnetic induction to convert electrical energy from one voltage level to another. This is existing technology and will not be described in detail here. The opposite side walls of the two sets of protective shells 103 are equipped with heat dissipation components 106, which facilitate the heat dissipation of the transformer body 105.

[0021] In this embodiment: the base 100 is installed to a designated outdoor location using fixing bolts. The transformer body 105 is then fixed to the base 100. The protective shell 103 is rotated to maintain its verticality, aligning the snap-fit ​​bracket 104 with the snap-fit ​​groove. The double-ended screw 101 is rotated to move the left and right movable seats 102 towards each other. The movable seats 102 then move the two protective shells 103 towards each other. The right protective shell 103 moves the snap-fit ​​bracket 104, causing it to snap into the inner cavity of the snap-fit ​​groove. The combination and fixing facilitates the limiting and fixing of the protective shell 103, preventing the protective shell 103 from deflecting, and facilitating the protection of the transformer body 105. The reverse double-headed screw 101 drives the two sets of moving seats 102 to move in opposite directions, causing the snap-fit ​​bracket 104 to move out of the inner cavity of the snap-fit ​​groove. At this time, the protective shell 103 can be rotated and unfolded for easy disassembly. This device makes it easy to combine and fix the protective shell 103, facilitates the protection of the transformer body 105, facilitates subsequent disassembly and maintenance, and helps to improve work efficiency.

[0022] The heat dissipation assembly 106 includes a heat dissipation frame 107. A cooling fan 108 is fixedly connected to the inner cavity of the heat dissipation frame 107, facilitating airflow for heat dissipation. Louvers 109 are evenly rotatably connected to the front and rear sidewalls of the inner cavity of the left heat dissipation frame 107, guiding airflow. The front ends of the louvers 109 penetrate the front sidewall of the heat dissipation frame 107 and are fixedly connected to gears 110, allowing the louvers 109 to rotate and oscillate. A mounting bracket 111 is fixedly connected to the front sidewall of the left heat dissipation frame 107, supporting the reciprocating screw 112. Reciprocating screws 112 are rotatably connected to the upper and lower sidewalls of the inner cavity of the mounting bracket 111. The lead screw 112 facilitates the reciprocating movement of the rack 113. The rack 113 is screwed to the outer wall of the reciprocating lead screw 112, which in turn drives the gear 110 to rotate. The left side wall of the rack 113 is located on the left side wall of the inner cavity of the mounting bracket 111, which facilitates the movement of the rack 113 on the mounting bracket 111 and prevents deflection. The gear 110 meshes with the rack 113. The front side wall of the left heat sink frame 107 is fixedly connected to the motor 114, which drives the reciprocating lead screw 112 to rotate. The output end of the motor 114 is connected to the top end of the reciprocating lead screw 112.

[0023] In this embodiment: the left-side cooling fan 108 draws outside air into the inner cavity of the heat sink frame 107, and the heat sink frame 107 guides the air to the outside of the transformer body 105 for air cooling. The motor 114 reciprocates the lead screw 112, which in turn drives the rack 113 to move back and forth. The rack 113 drives the gear 110 to rotate, which in turn drives the louvered plate 109 to rotate and swing, facilitating the guidance of the incoming airflow. The right-side cooling fan 108 draws in hot air from the outside of the transformer body 105, allowing the hot air to be discharged from the right side. This device facilitates the guidance and delivery of air, ensuring that the air is blown in evenly and cools the transformer body 105, thereby improving the heat dissipation efficiency.

[0024] The left and right side walls of the protective shells 103 on both sides are fixedly connected to soundproof covers 115. The soundproof covers 115 facilitate the blocking of noise. The bottom wall of the soundproof cover 115 has an air vent, and the inner wall of the air vent is fixedly connected to a dustproof net 116. The dustproof net 116 facilitates the filtering of dust.

[0025] In this embodiment: the soundproof cover 115 facilitates the absorption and isolation of the noise generated by the cooling fan 108 and the transformer body 105 during operation, so as to avoid excessive noise affecting the surrounding residents. The dustproof net 116 facilitates the filtration of air, so as to prevent impurities in the air from entering the interior and affecting the operation of the device.

[0026] The outer wall of the heat dissipation frame 107 is fixedly connected with a sound insulation shell 117, which facilitates noise isolation. The sound insulation shell 117 is located on the outside of the heat dissipation assembly 106.

[0027] In this embodiment, the soundproof shell 117 is provided to absorb and isolate the noise generated by the transformer body 105 during operation, thereby reducing environmental noise and improving the noise reduction effect of the device.

[0028] The inner wall of the snap-fit ​​groove is equipped with a sealing strip 118, and the top wall of the protective shell 103 is inclined.

[0029] In this embodiment, the sealing strip 118 is provided to facilitate the sealing of the inner cavity of the snap-fit ​​groove, avoid gaps that could lead to rainwater leakage, improve the sealing performance of the device, facilitate the protection of the transformer body 105 outdoors, and enhance the practicality of the device.
