Description

Technical Field

[0001] This utility model belongs to the field of power transformer technology, and more specifically, it relates to a waterproof and moisture-proof outdoor power transformer. Background Technology

[0002] Outdoor power transformers are electrical devices specifically designed for outdoor environments. They convert high-voltage electricity from the power grid into low-voltage electricity suitable for outdoor equipment. During transmission, they stabilize voltage, reduce energy loss, and ensure the safe and reliable operation of outdoor lighting, power tools, temporary power supply facilities, and other equipment, providing stable power support for outdoor scenarios. However, traditional outdoor power transformers have poor waterproofing and moisture resistance. Rainwater or moisture seeps into the transformer, causing corrosion of metal components such as the core and windings. Furthermore, the insulation performance of the insulating materials deteriorates significantly when damp, leading to faults such as inter-turn short circuits and winding breakdowns. This ultimately prevents the transformer from functioning properly, reducing its practicality. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a waterproof and moisture-proof outdoor power transformer. This solves the technical problem that traditional outdoor power transformers have poor waterproof and moisture-proof properties, and rainwater and moisture can easily seep in, causing corrosion of the iron core and windings, reduced insulation performance, short circuits, breakdowns, and other faults, making them unable to work properly and thus reducing their practicality.

[0004] The purpose and function of this waterproof and moisture-proof outdoor power transformer are achieved by the following specific technical means:

[0005] A waterproof and moisture-proof outdoor power transformer includes a frame-structured housing. A mounting plate is movably disposed within the housing, and a mounting component is provided at the bottom of the mounting plate. The mounting component is fitted onto the bottom of the housing, and a top cover is detachably fitted onto the top of the housing. The mounting plate also has a mounting groove, within which a transformer module is fixedly connected by multiple sets of screws. An isolation groove is provided at the end of the mounting component away from the mounting plate, within which a connector and an assembly plate are disposed. A switch is also provided on the assembly plate. Both the connector and the switch are electrically connected to the transformer module via wires. Heat dissipation grooves are provided through both sides of the housing, and heat dissipation plates are detachably disposed within these grooves.

[0006] The above technical solution further includes that positioning grooves are provided on both sides of the housing, and mounting sliders are provided in the mounting component and the top cover corresponding to the positioning grooves. The mounting component and the mounting sliders in the top cover are slidably disposed in the positioning grooves and fixed by screws.

[0007] The above technical solution further includes that the mounting component and the top cover are provided with assembly grooves, and rubber seals are replaced in the two sets of assembly grooves.

[0008] The above technical solution further includes that the assembly board is also provided with two sets of indicator lights, and the two sets of indicator lights are respectively connected to the switch and the transformer module.

[0009] The above technical solution further includes that the heat sink is provided with a heat-conducting fin on the side of the heat sink near the heat sink groove, and multiple sets of heat sink fins are provided on the other side of the heat sink.

[0010] The above technical solution further includes that the top of the top cover is provided with a hanging plate, and the hanging plate is provided with multiple sets of hanging holes.

[0011] The above technical solution further includes that the housing and the heat sink are both made of aluminum alloy; the mounting component, the mounting plate and the top cover are all made of plastic.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The mounting sliders inside the mounting components and top cover can be precisely embedded into the positioning grooves on both sides of the housing, forming a stable connection with screws. Simultaneously, assembly grooves are provided inside the mounting components and top cover, where rubber seals can be installed. Once the mounting components, top cover, and housing are in place, the seals tightly fill the gaps at the joints, forming a completely sealed space that effectively prevents rainwater and moisture from seeping into the housing. This structure prevents corrosion of the transformer core and windings due to contact with moisture, prevents performance degradation of insulation materials due to moisture, and thus reduces the possibility of electrical faults such as short circuits and breakdowns, ensuring the transformer operates normally in humid, rainy outdoor environments.

[0014] 2. Heat dissipation plates are detachably installed in the heat dissipation slots on both sides of the housing. The heat dissipation plate has a heat-conducting fin on the side near the heat dissipation slot. The heat-conducting fin is in direct contact with the heat-generating components of the transformer during operation, which can quickly conduct heat to the heat dissipation plate. Multiple sets of heat dissipation fins are installed on the other side of the heat dissipation plate to increase the contact area with the air. Heat dissipation is accelerated through air convection to ensure that the transformer maintains the normal operating temperature during operation and avoids the impact of heat accumulation on the transformer's performance and service life.

[0015] 3. A suspension plate is installed at the top of the top cover, with multiple sets of suspension holes. The transformer can be suspended and installed on outdoor walls, brackets, or other suitable locations using bolts, hooks, and other connectors. The casing is made of aluminum alloy, which has high strength and is lightweight; the mounting parts, mounting plate, and top cover are made of plastic, further reducing the overall weight and making the transformer installation process more convenient, easier for construction personnel to operate, and improving installation efficiency.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0023] like Figures 1 to 4 As shown, this utility model provides a waterproof and moisture-proof outdoor power transformer, including a frame-structured housing 1, a mounting plate 2 movably disposed inside the housing 1, and a mounting component 101 disposed at the bottom end of the mounting plate 2. The mounting component 101 is fitted onto the bottom end of the housing 1, and a top cover 102 is detachably fitted onto the top end of the housing 1. The mounting plate 2 is also provided with a mounting groove, in which a transformer module 3 is fixedly connected by multiple sets of screws. An isolation groove 103 is provided at the end of the mounting component 101 away from the mounting plate 2. A connector 4 and an assembly plate 104 are disposed in the isolation groove 103. A switch 5 is also provided on the assembly plate 104. Both the connector 4 and the switch 5 are electrically connected to the transformer module 3 through wires. Heat dissipation grooves are provided through both sides of the housing 1, and heat dissipation plates 105 are detachably disposed in the heat dissipation grooves. The frame structure housing 1 provides stable support for the internal components. The mounting plate 2 is movable inside the housing 1 to facilitate the installation and removal of the transformer module 3. The transformer module 3 is fixed in the mounting slot of the mounting plate 2 by screws to ensure that the transformer module 3 is placed stably and to prevent it from shaking or shifting during operation. The transformer module 3 can be an SCB18-3150 model transformer module.

[0024] The inner contour of mounting component 101 matches the outer contour of the bottom end of housing 1, and is nested onto the bottom end of housing 1 to form a tight connection; the top cover 102 is similarly detached and fitted onto the top of housing 1 in a nested structure. This detachable connection allows operators to quickly separate mounting component 101, top cover 102, and housing 1 in case of transformer failure, directly accessing internal components such as connector 4, switch 5, and transformer module 3 for inspection and replacement. An isolation groove 103 is provided at the end of mounting component 101 away from mounting plate 2. The isolation groove 103 serves to isolate rainwater. Simultaneously, after connector 4 and assembly plate 104 are inserted, electrical components are arranged in zones. This zoned arrangement makes the wiring paths between connector 4 and transformer module 3, and between switch 5 and other components, clear, reducing the possibility of tangled or crossed wires, and lowering signal interference and short-circuit risks.

[0025] The connector 4 has multiple terminals, each connected to the corresponding electrode of the transformer module 3 via wires, forming an input / output channel for electrical energy. The pins of the switch 5 are connected to the control circuit of the transformer module 3 via wires. This clear circuit connection method ensures a stable transmission of electrical energy from the connector 4 to the transformer module 3. After processing by the transformer module 3, the output is controlled according to the open / closed state of the switch 5. The assembly plate 104 serves as the mounting carrier for the switch 5, and its surface has fixing holes. The switch 5 is fixed to the holes with screws. Operators can control the on / off state of the entire transformer circuit by pressing and rotating the switch 5, meeting actual power consumption needs.

[0026] Symmetrical heat dissipation slots are distributed on both sides of the casing 1. The shape and size of the slots are determined through thermal flow analysis to ensure smooth airflow. The heat dissipation plate 105 is connected to the heat dissipation slots via clips or bolts, allowing for quick disassembly and installation. When the transformer generates heat during operation, the heat is conducted to the heat dissipation slots through the casing 1. The heat dissipation plate 105 is in close contact with the slots, rapidly absorbing heat and dissipating it into the surrounding air through its material properties. During long-term use, if dust accumulates on the surface of the heat dissipation plate 105, it can be directly removed for cleaning, preventing dust buildup from forming an insulating layer and ensuring that the heat dissipation plate 105 continues to provide efficient heat dissipation, maintaining the transformer's internal operating temperature range.

[0027] Both the housing 1 and the heat sink 105 are made of aluminum alloy; the mounting parts 101, mounting plate 2, and top cover 102 are made of plastic. The high thermal conductivity of aluminum alloy allows the heat generated during transformer operation to be conducted through the housing 1 to the heat sink 105, which then quickly dissipates the heat into the air, ensuring efficient heat dissipation. Simultaneously, the high strength of aluminum alloy provides stable support for the housing 1, resisting external pressure and preventing deformation. Its corrosion resistance also makes it suitable for outdoor environments, extending its service life. The mounting parts 101, mounting plate 2, and top cover 102 are made of plastic. Plastic is lightweight, facilitating installation and disassembly, reducing manual labor intensity. Furthermore, the insulation properties of plastic prevent external current from being conducted to these components, ensuring operator safety. Additionally, the lower cost of plastic reduces overall production costs.

[0028] like Figure 3 As shown, a hanging plate 601 is also provided at the top of the top cover 102, and multiple sets of hanging holes 602 are provided on the hanging plate 601. The hanging plate 601 at the top of the top cover 102 has multiple sets of hanging holes 602 on the hanging plate 601 into which bolts, hooks and other connecting parts can be inserted to suspend and fix the transformer to the wall, bracket or other supporting structure, so as to realize the installation in the air and avoid the space occupation or water immersion of the ground. The hanging installation method allows for smooth air circulation around the transformer, which is conducive to heat dissipation of the heat sink 105. Moreover, the hanging position can be flexibly adjusted according to the outdoor wiring requirements. During installation, the positioning is achieved by the hanging holes 602 to ensure the accurate installation position of the transformer and improve the installation efficiency.

[0029] like Figure 2 and Figure 4 As shown, positioning grooves 201 are provided on opposite sides of the housing 1. Mounting sliders 202 are provided in the mounting parts 101 and top cover 102 corresponding to the positioning grooves 201. The mounting sliders 202 in both the mounting parts 101 and top cover 102 are slidably disposed within the positioning grooves 201 and fixed with screws. Assembly slots are also provided in the mounting parts 101 and top cover 102, and rubber seals 301 are replaced in both sets of assembly slots. The positioning grooves 201 on both sides of the housing 1 form a sliding fit with the mounting sliders 202 in the mounting parts 101 and top cover 102. During installation, the mounting sliders 202 slide linearly along the positioning grooves 201, ensuring accurate relative positions of the mounting parts 101, top cover 102, and housing 1, and avoiding connection gaps or structural misalignment due to misalignment. After the slider and the groove are fixed with screws, a rigid connection is formed, making the mounting part 101, the top cover 102 and the housing 1 a complete force-bearing whole. When the transformer is transported, vibrated or subjected to external forces, the parts are prevented from loosening and shifting, and the internal components are ensured to be safe.

[0030] The guiding function of the positioning groove 201 and the mounting slider 202 eliminates the need for repeated alignment adjustments during installation. Operators can directly slide the mounting component 101 and the top cover 102 into place along the groove, reducing assembly time. Simultaneously, the seal 301 can be pre-installed within the assembly groove, preventing displacement or detachment during installation, further simplifying assembly steps and improving production efficiency.

[0031] The mounting grooves within the mounting component 101 and the top cover 102 provide installation space for the rubber seal 301. After the mounting component 101 and the top cover 102 are positioned and fixed by the slider and the groove, the seal 301 is compressed on the contact surface between the mounting groove and the housing 1, filling all gaps. This sealing structure effectively prevents rainwater and moisture from seeping in from the bottom interface between the mounting component 101 and the housing 1, and the top interface between the top cover 102 and the housing 1, avoiding moisture contact with internal electrical components such as the transformer module 3 and the connector 4, and preventing short circuits, corrosion, and other malfunctions caused by moisture.

[0032] like Figures 1 to 2 As shown, the assembly board 104 is also equipped with two sets of indicator lights 401, which are connected to the switch 5 and the transformer module 3, respectively. Firstly, the indicator lights 401 connected to the switch 5 can visually display the status of the switch 5. When the switch 5 is closed, the corresponding indicator light 401 lights up, indicating that the circuit is conducting. When the switch 5 is open, the indicator light 401 goes out, indicating that the circuit is disconnected, allowing operators to quickly confirm the circuit's continuity. Secondly, the indicator lights 401 connected to the transformer module 3 can reflect the operating status of the transformer module 3. When the transformer module 3 is operating normally, the corresponding indicator light 401 illuminates. When the transformer module 3 malfunctions or abnormally stops working, the indicator light 401 goes out or flashes, helping staff to promptly identify problems with the transformer module 3's operation and shortening troubleshooting time. Furthermore, the two sets of indicator lights 401 are located on the assembly board 104 in the same visible area, facilitating centralized observation and improving the efficiency of transformer operating status monitoring.

[0033] like Figures 1 to 2 As shown, a heat-conducting fin 501 is provided on the side of the heat sink 105 near the heat sink groove, and multiple sets of heat dissipation fins 502 are provided on the other side of the heat sink 105. The heat-conducting fin 501 on the side of the heat sink 105 near the heat sink groove is in contact with or close to the heat-generating components such as the transformer module 3 inside the housing 1, and quickly conducts heat to the heat sink 105. The multiple sets of heat dissipation fins 502 on the other side increase the heat dissipation area. When air flows through, it fully exchanges heat with the heat dissipation fins 502, accelerating heat dissipation. The heat-conducting fin 501 and the heat dissipation fins 502 work together to form an efficient heat dissipation path, ensuring that the heat of the transformer is discharged in time, maintaining the internal temperature stability, and avoiding the impact of high temperature on the performance and service life of the components.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
