Description

Technical Field

[0001] This utility model belongs to the technical field of cable branch boxes, specifically relating to an anti-condensation cable branch box. Background Technology

[0002] Cable distribution boxes are devices used for cable splicing or branching in power systems, primarily in 10kV and below power systems. Their main function is to achieve flexible power distribution within the power system without interrupting the main line's power supply, providing power connection points for users in different directions or with different needs. Currently, cable distribution boxes are prone to condensation in humid environments due to temperature differences between the inside and outside, leading to corrosion of internal components, decreased insulation performance, and even short circuits.

[0003] Problems with existing technology:

[0004] Currently, the anti-condensation structure used in cable distribution boxes only dehumidifies by adding hot air into the box, but cannot effectively guide the moisture away. As a result, condensation can still easily occur on electrical components. At the same time, since there is no sealing structure at the cable entry end, external condensation can easily penetrate into the box. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-condensation cable branch box, which can actively guide moisture to condense into water droplets in the shell and collect them through the anti-condensation mechanism, so as to avoid condensation on electrical components and improve the reliability of moisture protection. The sealing component can also prevent external moisture from entering the box through the cable.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An anti-condensation cable branch box includes a box body, wherein the front and back of the box body are hinged with boxes;

[0008] An anti-condensation mechanism is fixedly installed on one side of the inside of the enclosure, and a sealing component is provided at the bottom of the enclosure for connection with the cable sleeve;

[0009] The anti-condensation mechanism includes an outer shell fixedly installed inside the box, a hot air blower fixedly installed on the top of the outer shell through a collection box, the bottom of the collection box communicating with the condensation component, and a water collection box fixedly installed on the bottom of the outer shell.

[0010] The anti-condensation mechanism is provided in two sets, and is distributed in a mirror image on both sides of the inside of the box. A through groove is provided on one side of the outer shell, and a drainage groove is provided at the bottom inside the outer shell.

[0011] The collection box is fixedly installed to the outer shell, the hot air blower passes through the box and is fixedly installed to the collection box, and the condensation component is threadedly installed to the collection box.

[0012] The condensation assembly includes a connecting pipe threaded to the bottom of the collection box. A return pipe is fixedly installed on one side of the bottom of the connecting pipe through an air inlet, and an outlet is provided on the other side of the bottom of the connecting pipe.

[0013] The top of the connecting pipe is connected to the air inlet, the end of the return pipe is connected to the outlet, and one end of the connecting pipe has a through hole that is connected to the outlet.

[0014] The sealing assembly includes a sealing sleeve, a groove on one side of the sealing sleeve, and a sealing ring on the top of the sealing sleeve.

[0015] Both the sealing sleeve and the sealing ring are made of rubber. The sealing ring has multiple layers and is stacked. Cutting lines are provided between the multiple layers of the sealing ring.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes anti-condensation mechanisms installed on both sides of the interior of the housing. A hot air blower on one side of the collection box sends hot air into the collection box and through a connecting pipe and air inlet to the return pipe. The heat radiated from the return pipe comes into contact with the humid air, causing it to condense into water droplets that adhere to the surface of the return pipe. These water droplets are then collected in the water collection box as they fall naturally. Furthermore, because the other end of the connecting pipe has a through hole connected to the outlet, which in turn connects to the end of the return pipe, hot air can enter the interior of the housing for drying, thus preventing condensation on the surface of electrical components and avoiding potential safety hazards.

[0018] This utility model features a sealing component at the bottom of the enclosure, with a sealing sleeve that can be snapped into the enclosure via a slot. Multiple sealing rings are stacked on top of the sealing sleeve, and cutting lines are provided between the sealing rings, allowing them to be cut to accommodate cables of different diameters. The sealing component also prevents external moisture from entering the enclosure through the cable. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-6 As shown, an anti-condensation cable branch box includes a box body 1, with a door 2 hinged to the front and back of the box body 1.

[0029] An anti-condensation mechanism 3 is fixedly installed on one side of the inside of the enclosure 1, and a sealing component 4 is installed at the bottom of the enclosure 1 and connected to the cable sleeve.

[0030] The anti-condensation mechanism 3 includes an outer shell 31 fixedly installed inside the housing 1. A hot air blower 33 is fixedly installed on the top of the outer shell 31 through a collection box 32. The bottom of the collection box 32 is connected to the condensation component 34. A water collection box 35 is fixedly installed on the bottom of the outer shell 31.

[0031] See attached document Figure 2 , Figure 3 and Figure 4 In this embodiment, two sets of anti-condensation mechanisms 3 are provided and are distributed in a mirror image on both sides of the inside of the housing 1. A through groove is provided on one side of the outer shell 31, and a drainage groove is provided at the bottom inside the outer shell 31.

[0032] In the above embodiment, since the anti-condensation mechanism 3 is located on both sides of the inside of the box 1, and the electrical components inside the box 1 are located between the two sets of anti-condensation mechanisms 3, when humid air enters the inside of the box 1, the humid air can be drawn away by the two sets of anti-condensation mechanisms 3 and condensation can occur.

[0033] Specifically, the collection box 32 is fixedly installed with the outer casing 31, while the hot air blower 33 penetrates the housing 1 and is fixedly installed with the collection box 32. Therefore, by starting the hot air blower 33, hot air can be sent through the collection box 32 into the interior of the condensation assembly 34, so that the moisture in the humid air condenses on the surface of the condensation assembly 34.

[0034] Furthermore, when the condensed water droplets are too large, they can enter the water collection box 35 through the drainage groove at the bottom of the outer shell 31 under their own weight, thereby collecting the water. Therefore, the condensation component 34 and the water collection box 35 can prevent condensation from forming on the surface of electrical components. The specific structure and function of the condensation component 34 will be described and introduced in detail below.

[0035] Please refer to the appendix for details. Figure 2 , Figure 4 and Figure 5 The condensation assembly 34 includes a connecting pipe 341 threadedly installed at the bottom of the collection box 32, and a return pipe 342 is fixedly installed on one side of the bottom of the connecting pipe 341 through an air inlet 343, while an outlet 344 is provided on the other side of the bottom of the connecting pipe 341.

[0036] According to the above structure, since the top of the connecting pipe 341 is connected to the air inlet 343, hot air can be sent into the interior of the return pipe 342 through the connecting pipe 341 and the air inlet 343. At the same time, since the end of the return pipe 342 is connected to the outlet 344, and one end of the connecting pipe 341 is provided with a through hole and connected to the outlet 344, the hot air inside the return pipe 342 can be discharged into the interior of the box 1 through the through hole of the connecting pipe 341 to dry the air inside the box 1 and further avoid condensation.

[0037] See attached document Figure 2 and Figure 6 In this embodiment, the sealing assembly 4 includes a sealing sleeve 41, a groove 42 is provided on one side of the sealing sleeve 41, and a sealing ring 43 is provided on the top of the sealing sleeve 41.

[0038] In the above embodiment, both the sealing sleeve 41 and the sealing ring 43 are made of rubber. The sealing ring 43 has multiple layers and is stacked. At the same time, a cutting line 44 is provided between the multiple layers of sealing rings 43. Therefore, the sealing ring 43 can be cut by the cutting line 44, so that cables of different diameters can be used.

[0039] Furthermore, the sealing sleeve 41 can be fixed to the housing 1 through the slot 42. Therefore, under the elastic action of the sealing sleeve 41 and the sealing ring 43, it can be tightly attached to the surface of the cable, thereby preventing external moisture from entering the interior of the housing 1 through the cable.

[0040] The working principle of this utility model is as follows: After the sealing component 4 is installed and fixed to the box 1 through the slot 42, the sealing ring 43 can be cut according to the different diameters of the cable and the cutting line 44. Then the cable can be passed through the sealing component 4 and sent into the interior of the box 1. When humid air enters the branch box during use, the hot air can be sent to the interior of the return pipe 342 through the collection box 32 and the condensation component 34 by starting the hot air heater 33. The heating of the return pipe 342 can cause the moisture in the humid air to condense into water droplets on the surface of the return pipe 342 and drip naturally onto the bottom of the outer shell 31. The water droplets can enter the water collection box 35 for collection through the drainage groove at the bottom of the outer shell 31. At the same time, a through hole is opened at the other end of the connecting pipe 341, and the outlet 344 at the bottom of the other side of the connecting pipe 341 is connected to the end of the return pipe 342. Therefore, hot air can enter the interior of the box 1 and, in conjunction with the anti-condensation mechanism 3, prevent condensation from occurring inside the box 1.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
