[0032] The utility model provides an outdoor distribution box.

[0033] See also Figure 1 In one embodiment of the utility model, the outdoor distribution box includes a box body 10, a top cover 20 and a water diversion assembly, the box body 10 is provided with an inner cavity 10a; the top cover 20 is detachably connected to the top of the box body 10; the water diversion assembly is installed between the top cover 20 and the box body 10, and is located at the edge of the top cover 20, for receiving rainwater and guiding it to the drainage position.

[0034] The outdoor distribution box includes a box body 10, which is provided with an inner cavity 10a, and the inner cavity 10a is used to accommodate various distribution equipment, such as circuit breakers, cable connectors, etc. The box body 10 is made of high-quality stainless steel material, which has good corrosion resistance and mechanical strength. The top cover 20 is detachably connected to the top of the box body 10. The design of the top cover 20 is conducive to convenient inspection and maintenance of the equipment inside the distribution box. Bolts that are easy to disassemble are provided on the top cover 20. By tightening or loosening the bolts, the top cover 20 can be quickly connected and separated from the box body 10.

[0035] The water diversion assembly is installed between the top cover 20 and the box body 10 and is located at the edge of the top cover 20. When rain falls, the water diversion assembly will receive rainwater and guide it to the drainage position. The rainwater is discharged to the outside of the box body 10 to ensure that the equipment in the box body 10 is dry and avoid equipment failure caused by rainwater soaking. When it is necessary to inspect and maintain the equipment inside the distribution box, unscrew the bolts on the top cover 20 and remove the top cover 20 for convenient inspection and maintenance.

[0036] The distribution box of the utility model effectively solves the problem of insufficient waterproof performance of outdoor distribution boxes in the prior art by providing a unique water diversion component. The water diversion component of the present application can promptly receive and guide rainwater to the drainage position, thereby ensuring that the inside of the box body 10 is dry, greatly improving the waterproof performance of the outdoor distribution box.

[0037] Secondly, the top cover 20 of the utility model adopts a detachable connection mode, which is convenient for inspection and maintenance of the inside of the distribution box. In the prior art, once a fault occurs inside the distribution box, it is often necessary to remove the outer shell as a whole, which is time-consuming and laborious. The detachable top cover 20 design of the present application makes inspection and maintenance work more convenient, improves work efficiency, and reduces maintenance costs.

[0038] In one embodiment, the water diversion assembly includes a water diversion frame 31 and a drainage pipe. The water diversion frame 31 is installed between the top cover 20 and the box body 10 and is located at the edge of the top cover 20. The water diversion frame 31 is provided with a water diversion groove 31a, which is used to receive rainwater and guide it to the drainage position. The drainage pipe is connected to the end of the water diversion groove 31a and is used to drain the rainwater to the drainage position.

[0039] Specifically, the inclined setting of the water guide frame 31 is conducive to receiving rainwater and guiding it to the drainage position. The drain pipe is connected to the lower end of the water guide frame 31, so that the rainwater can be discharged to the outside of the box 10 faster under the action of gravity. The utility model effectively solves the problem of low efficiency of rainwater collection and discharge in the prior art by setting a unique water guide frame 31 and a drain pipe structure. The water guide frame 31 is located at the edge of the top cover 20 and is provided with a special water guide groove 31a, which can maximize the reception of rainwater and quickly guide it to the drainage position. This design not only improves the collection efficiency of rainwater, but also avoids the overflow problem caused by rainwater being retained on the surface of the top cover 20. The direct connection between the water guide groove 31a and the drain pipe realizes the rapid discharge of rainwater and eliminates the accumulation of water and potential flood risks caused by poor drainage. This reduces the maintenance cost to a certain extent and improves the stability and durability of the entire system.

[0040] In another embodiment, in order to improve the drainage effect of the water diversion assembly, the structure of the water diversion frame 31 can be optimized. The water diversion frame 31 adopts a wave-shaped structure, which helps to increase the drainage area and improve the drainage efficiency of the water diversion assembly.

[0041] In one embodiment, see Figure 1 The transverse cross-sectional shape of the water diversion groove 31a is designed to be V-shaped or inverted trapezoidal.

[0042] In Example 1, the transverse cross-section of the water diversion groove 31a is designed to be V-shaped. The design of the V-shaped cross-section is conducive to increasing the speed of the water flow and guiding the direction of the water flow, thereby increasing the drainage efficiency. Specifically, the bottom width of the V-shaped cross-section is B1, the angle between the two sides of the hypotenuse and the bottom is θ1, and the height of the hypotenuse is H1. The V-shaped cross-section design helps to reduce the contact area between the water flow and the groove wall, reduce the friction between the water flow and the groove wall, and enable the water flow to flow to the groove outlet more quickly. When the water flow enters the V-shaped cross-section of the water diversion groove 31a, due to the shape of the cross-section, the water flow automatically concentrates and accelerates to flow to the groove outlet. No additional power equipment is required during the operation, and drainage can be completed only by relying on the dynamic pressure of the water flow itself.

[0043] In Example 2, the transverse cross-section of the water diversion groove 31a is designed to be an inverted trapezoid. The inverted trapezoidal cross-section also has efficient drainage performance and may be better than the V-shaped cross-section in certain specific scenarios. The inverted trapezoidal cross-section design allows the water flow to gradually accelerate while flowing in the groove, while maintaining a certain water flow depth, which is suitable for occasions with large water flow. When the water flow enters the water diversion groove 31a with an inverted trapezoidal cross-section, the water flow first diffuses in the wider bottom area, then gradually concentrates during the upward flow, and finally flows quickly to the outlet of the groove.

[0044] In one embodiment, see Figure 1 The water guide frame 31 includes a fixed frame 311, an upper water guide bar 312 and a lower water guide bar 313. The fixed frame 311 is arranged between the top cover 20 and the box body 10; the upper water guide bar 312 is connected to one end of the fixed frame 311, and the upper water guide bar 312 is provided with a water guide groove 31a; the lower water guide bar 313 is connected to the other end of the fixed frame 311 and is arranged adjacent to the box body 10; the lower water guide bar 313 is provided with a water guide groove 31a; and the lower water guide bar 313 and the upper water guide bar 312 are arranged in a horizontally staggered manner.

[0045] By setting a fixing frame 311 between the top cover 20 and the box body 10 and connecting the upper and lower water diversion bars 313, the water flow is effectively guided to prevent the waste of water resources. The configuration of the upper water diversion bar 312 and the lower water diversion bar 313 and their unique horizontal dislocation arrangement optimize the water flow path, improve the water diversion efficiency, and solve the problem of poor water flow guidance in the prior art. The design of the water diversion groove 31a on the upper water diversion bar 312 and the lower water diversion bar 313 not only strengthens the water diversion function, but also helps to improve the uniform distribution of water flow. This design reduces the problem of excessive local pressure in the box body 10 caused by uneven water flow, thereby extending the service life of the entire system.

[0046] The fixing frame 311 of Example 1 is arranged between the top cover 20 and the box body 10. The fixing frame 311 is made of aluminum alloy material and has high strength and corrosion resistance. The upper water diversion bar 312 is connected to one end of the fixing frame 311. The upper water diversion bar 312 is made of polyvinyl chloride material and has good waterproof performance. The upper water diversion bar 312 is provided with a water diversion groove 31a for collecting and guiding water flow. The lower water diversion bar 313 is connected to the other end of the fixing frame 311 and is arranged adjacent to the box body 10. The lower water diversion bar 313 is also made of polyvinyl chloride material and is provided with a water diversion groove 31a for collecting and guiding water flow. The lower water diversion bar 313 is arranged horizontally staggered with the upper water diversion bar 312, so that the water flow flows smoothly into the lower water diversion bar 313 after passing through the upper water diversion bar 312, effectively preventing the water flow from directly impacting the box body 10 and reducing the impact force of the water flow on the box body 10.

[0047] The main difference between Example 2 and Example 1 lies in the material of the fixing frame 311 and the structure of the water diversion bar. In this embodiment, the fixing frame 311 is made of stainless steel material, which has higher strength and corrosion resistance. The water diversion groove 31a of the upper water diversion bar 312 and the lower water diversion bar 313 adopts a semicircular structure, which improves the water flow guiding efficiency. The horizontal misalignment arrangement angle of the lower water diversion bar 313 and the upper water diversion bar 312 is 30 degrees to meet the water flow guiding requirements of different occasions. In practical applications, the material of the fixing frame 311, the structure and arrangement angle of the water diversion bar, etc. can be adjusted as needed to adapt to different usage scenarios.

[0048] In one embodiment, see Figure 1 The drainage pipe includes a first pipe section and a second pipe section, the first pipe section is connected to the end of the upper water diversion bar 312, and the second pipe section is connected to the end of the lower water diversion bar 313.

[0049] The first pipe section is made of PVC material and is cylindrical in shape. One end of the first pipe section is provided with a thread for connecting with the threaded hole at the end of the upper water guide bar 312. The second pipe section is also made of PVC material and has the same shape, inner diameter and outer diameter as the first pipe section. One end of the second pipe section is provided with a thread for connecting with the threaded hole at the end of the lower water guide bar 313. The upper water guide bar 312 and the lower water guide bar 313 are both made of stainless steel and are strip-shaped. The ends of the upper water guide bar 312 and the lower water guide bar 313 are respectively provided with threaded holes matching the first pipe section and the second pipe section.

[0050] Connect the threaded end of the first pipe section to the threaded hole of the upper water guide bar 312, and ensure that the connection is tight. Then, connect the threaded end of the second pipe section to the threaded hole of the lower water guide bar 313, and also ensure that the connection is tight. After completing the above steps, the drainage pipe can be put into use. During the drainage process, water enters the first pipe section through the upper water guide bar 312, then flows into the second pipe section, and finally is discharged through the lower water guide bar 313.

[0051] The drainage pipe of the utility model realizes the continuity and smoothness of water flow guidance through the design of two pipe sections, avoids the problem of increased water flow resistance caused by the excessive length of a single pipe section, thereby reducing the loss of water flow speed and improving drainage efficiency. Due to the split design of the first pipe section and the second pipe section, it can be adjusted according to actual installation needs, which not only reduces material waste, but also reduces the overall cost, meeting the requirements of resource conservation and environmental protection. Through the connection of the upper and lower pipe sections, the impact force of the water flow is dispersed, the system vibration and noise caused by the impact of the water flow are reduced, and the stability and service life of the drainage system are improved.

[0052] In one embodiment, see Figure 1 The water guide frame 31 also includes a sealing strip 314, which is installed between the lower water guide strip 313 and the box body 10 to seal the gap between the lower water guide strip 313 and the box body 10.

[0053] In practical applications, when water flows through the lower water guide bar 313, the sealing strip 314 can effectively prevent the water from entering the gap between the lower water guide bar 313 and the housing 10, thereby improving water utilization and preventing water resource waste.

[0054] The sealing strip 314 can be made of rubber, silicone or other materials with certain elasticity and water resistance to ensure the sealing effect and service life. The sealing strip 314 can be installed by bonding, snapping, etc. to ensure that the sealing strip 314 is firmly connected to the lower water guide strip 313 and the box body 10.

[0055] Optionally, the water guide frame 31 further includes a bracket, which is arranged inside the box body 10 and is used to support the lower water guide bar 313. The structure of the bracket can improve the stability of the lower water guide bar 313 and further ensure the sealing effect. The material of the bracket can be selected from metal, plastic and other materials with certain strength and corrosion resistance.

[0056] In one embodiment, see Figure 1 The outlet of the drainage pipe is equipped with a mosquito net, which is used to prevent mosquitoes and other small animals from entering.

[0057] A mosquito net is provided at the outlet of the drain pipe, and the mosquito net is fixed to the fixing frame 311 by setting fasteners, so as to realize the connection between the drain pipe and the mosquito net. The drain pipe adopts a PVC drain pipe of standard size, which has good corrosion resistance and strength. The mosquito net is woven with stainless steel wire, which has good elasticity and the ability to intercept small animals such as mosquitoes. The fixing frame 311 is made of ABS material, which has good weather resistance and stability, and is used to fix the mosquito net. The fasteners are made of stainless steel and are used to tightly connect the fixing frame 311 to the drain pipe.

[0058] In another embodiment, the mosquito-proof net is detachably connected to the pipe opening of the drain pipe, so as to be easy to clean and replace. When the mosquito-proof net needs to be cleaned or replaced, only the fastener needs to be loosened and the mosquito-proof net can be removed.

[0059] In one embodiment, see Figure 1 A water guide bar 21 is provided at the edge of the top cover 20 , and the water guide bar 21 is arranged to be inclined downward relative to the edge of the top cover 20 .

[0060] The top cover 20 of this embodiment is designed with a water guide bar 21, so that the top cover 20 can effectively guide the water flow to the edge of the top cover 20 when it rains, thereby allowing the water flow to be discharged smoothly, avoiding the water flow from invading the interior of the top cover 20, and improving the service life and reliability of the product.

[0061] The top cover 20 is made of ABS material, which has certain strength and toughness and can withstand a certain degree of impact. The water guide bar 21 is made of silicone material, which has excellent elasticity and anti-aging performance. The connection between the water guide bar 21 and the top cover 20 adopts a hot melt welding process to ensure a firm connection and not easy to fall off.

[0062] In one embodiment, see Figure 1 , the outer surface of the top cover 20 is provided with a hydrophobic coating.

[0063] Specifically, the outer surface of the top cover 20 is provided with a hydrophobic coating, and the material of the hydrophobic coating is a nano-scale hydrophobic organic silicon compound, which has excellent weather resistance and hydrophobic properties and can effectively prevent moisture from accumulating on the surface of the top cover 20 .

[0064] During use, when the surface of the top cover 20 is affected by moisture, the hydrophobic coating can quickly cause the moisture to form water droplets, which slide down along the inclined direction of the surface of the top cover 20 under the action of gravity, thereby effectively preventing moisture from accumulating on the surface of the top cover 20.

[0065] Optionally, the hydrophobic coating has a thickness of about 5-10 μm and is evenly coated on the outer surface of the top cover 20 by spraying, brushing or roller coating. The top cover 20 is made of aluminum alloy material, which has high strength and light weight. Its outer surface is anodized to improve corrosion resistance and provide a good foundation for the adhesion of the hydrophobic coating.

[0066] In one embodiment, see Figure 1 The outer surface of the top cover 20 is provided with a plurality of water guiding indentations 22, and the plurality of water guiding indentations 22 are used to guide rainwater to be discharged to other locations.

[0067] On rainy days, when rainwater flows to the outer surface of the top cover 20, due to the presence of the water-guiding indentations 22, the rainwater will quickly flow along the water-guiding indentations 22 to the set drainage position, such as the drainage holes on the edge of the top cover 20, thereby effectively reducing the water accumulation on the surface of the top cover 20 and improving the waterproof performance of the building. The main function of these water-guiding indentations 22 is to guide rainwater to other locations, thereby reducing the water accumulation on the surface of the top cover 20 and improving the drainage performance of the top cover 20. Optionally, five water-guiding indentations 22 are evenly distributed on the outer surface of the top cover 20, and the shape of these water-guiding indentations 22 is semicircular.

[0068] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
