Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic snow melting power supply assembly boxes, specifically a modular assembly box for a photovoltaic snow melting power supply. Background Technology

[0002] Photovoltaic snow melting power is a new type of energy system that combines photovoltaic power generation and snow melting technology. It maintains power generation efficiency in low-temperature winter environments by generating electricity from both sides of the photovoltaic panels and melting snow with heat. When the photovoltaic panels are covered with snow in winter, the double-sided power generation technology (double-glass modules) diffuses sunlight through the snow to the back side, while the heat generated by power generation melts the snow on the front side, reducing the impact of snow on power generation efficiency. The photovoltaic snow melting power assembly box is a device that gathers the power from multiple photovoltaic panels connected in series and parallel to one location, and then sends it to the inverter for conversion through DC wires. The assembly box can also play a role in protecting and monitoring the system, helping the power station maintain a stable working state.

[0003] Currently, in existing technologies, the assembly box of photovoltaic snow melting power supply is a single box structure. During installation, operators need to go deep into the interior of the assembly box to carry out the installation, which makes the installation of photovoltaic snow melting power supply assembly box inconvenient. Therefore, there is a need to propose a modular assembly box for photovoltaic snow melting power supply. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a modular assembly box for a photovoltaic snow melting power source. (Refer to...) Figures 1-5 A modular assembly box for a photovoltaic snow melting power supply includes a box body 1, an inspection door 11 on one side of the box body 1, an assembly mechanism 3 on the other side of the box body 1, a rainproof roof 2 on the top of the box body 1, and casters 12 on the bottom of the box body 1. The rainproof roof 2 on the top of the box body 1 improves the box body 1's ability to prevent water and snow accumulation. The inspection door 11 on one side of the box body 1 facilitates maintenance by maintenance personnel. The assembly mechanism 3 can be disassembled from the box body 1, making the assembly mechanism 3 a separate module. This achieves the modular purpose of the photovoltaic snow melting power supply assembly box. The box body 1, with the help of the casters 12, can be moved easily. The relevant components of the photovoltaic snow melting power supply are first installed on the assembly mechanism 3, and then the assembly mechanism 3 is installed on the box body 1, thereby improving the convenience of installing the relevant components of the photovoltaic snow melting power supply.

[0025] Assembly mechanism 3 includes a back plate 31, which is inserted into one side of the housing 1. A mounting guide rail 32 is fixedly connected to the inner side of the back plate 31, and a rod 33 is also fixedly connected to the inner side of the back plate 31. A fixing frame 35 is fixedly connected to the inner wall of the housing 1. A locking block 38 is slidably connected to the inner cavity of the fixing frame 35. A spring 39 is provided on the opposite side of the locking block 38. The locking block 38 engages with the rod 33. A screw 36 is provided inside the fixing frame 35, and a limit frame 37 is provided at the end of the screw 36. The limit frame 37 engages with the locking block 38 and slides. By inserting the rod 33 on the back plate 31 into the inner cavity of the fixing frame 35 and rotating the screw 36, the screw... 36 pushes the limiting bracket 37 to slide, the limiting bracket 37 pushes the two locking blocks 38 to clamp inward and lock the insertion rod 33, so that the back plate 31 is stably installed on one side of the box 1, and there are no gaps in the box 1, reducing the probability of rain and snow entering the box 1. Rotate the screw 36 in the opposite direction, the screw 36 can drive the limiting bracket 37 to slide in the opposite direction. After the limiting bracket 37 removes the restriction on the locking blocks 38, the rebound force of the spring 39 pushes the two locking blocks 38 to remove the restriction on the insertion rod 33, so that the back plate 31 can be removed from one side of the box 1, thereby realizing the modularization of the back plate 31 and making it easy to disassemble and assemble.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The side wall of the box 1 is provided with a side groove 313. A sealing strip 314 is fixedly connected to the inner side of the back plate 31. The sealing strip 314 and the side groove 313 are engaged and snapped together. A positioning plate 315 is fixedly connected to the inner side of the back plate 31. The positioning plate 315 is engaged and inserted into the inner wall of the box 1. The back plate 31 is installed on one side of the box 1. The sealing strip 314 on the back plate 31 is inserted into the side groove 313 on the box 1, which reduces the gap at the joint between the box 1 and the back plate 31, thereby reducing the probability of rain and snow entering the box 1 from the joint between the box 1 and the back plate 31. When the back plate 31 is installed, the positioning plate 315 on the back plate 31 is inserted into the inner wall of the box 1, which facilitates the stable docking of the back plate 31 and the box 1.

[0027] Reference Figure 2 , Figure 3 and Figure 5The insert rod 33 has a slot 34 on its surface. One end of the locking block 38 is engaged inside the slot 34. One end of the screw 36 passes through one side of the fixing frame 35 and is threadedly connected to the fixing frame 35. The end of the screw 36 is rotatably connected to one side of the limiting frame 37. The end of the limiting frame 37 has a first inclined surface 310. One side of the locking block 38 has a second inclined surface 311. The first inclined surface 310 and the second inclined surface 311 cooperate and slide. Guide rods 312 are fixedly connected to both sides of the locking block 38. The guide rods 312 pass through the end of the fixing frame 35 and are slidably connected to the fixing frame 35. The insert rod 33 is inserted into the inner cavity of the fixing frame 35. The screw 36 is rotated, and the screw 36 is located in the fixing frame 35. 5. Move and push the limiting frame 37 to move. The first inclined surface 310 at the end of the limiting frame 37 cooperates with the second inclined surface 311 on the locking block 38 to push the two locking blocks 38 inward to clamp. The locking block 38 cooperates with the guide rod 312 to slide stably in the inner cavity of the fixing frame 35. The end of the locking block 38 is inserted into the slot 34 of the insertion rod 33, so that the insertion rod 33 can be stably inserted into the inner cavity of the fixing frame 35, thereby making the back plate 31 stably installed on one side of the box 1. Rotate the screw 36 in the opposite direction, the limiting frame 37 slides in the opposite direction, and the rebound force of the spring 39 pushes the end of the locking block 38 out of the slot 34 of the insertion rod 33, so that the insertion rod 33 can be removed from the fixing frame 35.

[0028] Working principle: In use, first install the components of the photovoltaic snow melting power supply on the back plate 31 and mounting rail 32 of the assembly mechanism 3. Then, install the back plate 31 on one side of the housing 1. The sealing strip 314 on the back plate 31 is inserted into the side groove 313 of the housing 1. The positioning plate 315 is inserted into the inner cavity of the housing 1 to facilitate the docking of the back plate 31 with the housing 1. The insertion rod 33 is inserted into the inner cavity of the fixing frame 35. Rotate the screw 36, and the screw 36 pushes the limiting frame 37 to slide. The first inclined surface 310 at the end of the limiting frame 37 cooperates with the... The second inclined surface 311 of the locking block 38 pushes the two locking blocks 38 into the slot 34 of the insertion rod 33. The locking blocks 38, in conjunction with the guide rod 312, slide stably in the inner cavity of the fixing frame 35. The spring 39 is compressed, thereby making the insertion rod 33 stably inserted into the inner cavity of the fixing frame 35. After assembly, the inspection door 11 is closed, and the rainproof top 2 is installed on the top of the box 1 to improve the rain and snow protection effect of the box 1. The box 1, in conjunction with the pulley 12, can be moved easily, thereby improving the convenience of moving the box 1.
