Description

Technical Field

[0001] This utility model belongs to the field of repeater chassis technology, specifically relating to a waterproof and moisture-proof repeater chassis for underground power stations. Background Technology

[0002] A repeater is a wireless signal relay device, and a repeater enclosure is the protective shell used to house the repeater equipment. Because underground power stations are typically located underground or inside mountains, moisture from the surrounding soil and rocks constantly seeps in, resulting in high humidity. Therefore, when using repeaters in underground power stations, a waterproof and moisture-proof repeater enclosure is required to protect the repeater. The enclosure usually consists of two hinged half-enclosures, which are fitted together to separate the inside and outside of the enclosure.

[0003] In existing underground power station waterproof and moisture-proof repeater cabinets, the two half-cabinets are usually directly and tightly attached during use. However, the attaching surfaces inevitably wear down due to opening and closing or weathering, making it difficult for the two half-cabinets to fit tightly together. This results in gaps between the two half-cabinets, reducing their waterproof and moisture-proof performance and compromising their reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof and moisture-proof repeater enclosure for underground power stations. It can absorb water and moisture entering the gap between the first and second enclosures through the protective strip, thereby improving the reliability of waterproofing and moisture-proofing. Furthermore, the protective strip in the groove can be replaced without disassembling the first and second enclosures. The cutter cuts the protective strip while also blocking the outside of the through hole, thus improving convenience.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A waterproof and moisture-proof repeater enclosure for an underground power station includes a first enclosure and further includes:

[0007] The second box is hinged to the first box. A groove is provided on the side of the second box near the first box. A protective strip is slidably connected in the groove. A through hole is provided on the inner wall of the second box. The through hole is slidably engaged with the protective strip. The groove is connected to the outside of the second box through the through hole.

[0008] The housing is fixedly connected to the outside of the second housing, and a rotating shaft is rotatably connected inside the housing. The protective strip is wrapped around and fixedly connected to the rotating shaft at one end near the housing.

[0009] A cutting mechanism is provided on the second housing. The cutting mechanism includes a cutter that is slidably connected to the second housing. The cutter is located at the end of the protective strip away from the rotating shaft.

[0010] One end of the protective strip is pulled outward along the through hole, which drives the rotating shaft to rotate, causing the part of the protective strip located inside the housing to move into the groove, and the cutter slides and cuts the protective strip.

[0011] The second housing has a cutting groove located below the cutter, and the cutting groove and the cutter slide in a vertical direction.

[0012] The cutter has a groove, and the second housing is fixedly connected to a slide bar. The groove and the slide bar slide together in a vertical direction.

[0013] The lower end of the cutter is designed to be angled.

[0014] The housing includes a fixed shell that is fixedly connected to the second housing, the fixed shell being rotatably connected to a rotating shaft, and a cover plate that is detachably connected to one side of the fixed shell.

[0015] An observation window is provided on the cover plate, and the observation window is fixedly connected to the housing.

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

[0017] The protective strip installed between the first and second housings in this invention absorbs water and moisture, reducing the amount of water and moisture entering the interior through the gap between the first and second housings, thereby improving the reliability of waterproofing and moisture protection.

[0018] When the protective strip of this utility model gets wet, the end of the protective strip is pulled outward, so that the part of the protective strip located inside the shell moves into the groove to replenish the part of the protective strip that has been pulled out. This makes it easy to replace the protective strip in the groove without disassembling the first and second boxes, thus improving the convenience of waterproofing and moisture protection.

[0019] The cutting mechanism of this utility model facilitates the cutting of the protective strip, while also keeping the through hole from being connected to the outside of the second housing, thus preventing the protective strip from moving outward and detaching from the second housing, thereby improving convenience.

[0029] 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 implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figures 1 to 7 As shown, a waterproof and moisture-proof repeater enclosure for an underground power station includes a first enclosure 10 and a second enclosure 20, which is hinged to the first enclosure 10. A groove 21 is provided on the side of the second enclosure 20 near the first enclosure 10, and a protective strip 22 is slidably connected in the groove 21. A through hole 23 is provided on the inner wall of the second enclosure 20, and the through hole 23 is slidably engaged with the protective strip 22. The groove 21 communicates with the outside of the second enclosure 20 through the through hole 23. A housing 30 is fixedly connected to the outside of the second enclosure 20, and a rotating shaft 31 is rotatably connected inside the housing 30. One end of the protective strip 22 near the housing 30 is wrapped around and fixedly connected to the rotating shaft 31. A cutting mechanism 40 is disposed on the second enclosure 20 and includes a cutter 41 slidably connected to the second enclosure 20. The cutter 41 is located at the end of the protective strip 22 away from the rotating shaft 31.

[0031] It should be noted that the first box 10 and the second box 20 are detachably connected together by bolts (not shown in the figure), the inside of the shell 30 is connected to the groove 21, and the protective strip 22 is wrapped around the rotating shaft 31 in a spiral shape. The protective strip 22 is made of water-absorbing material.

[0032] In this embodiment, when external water and moisture enter the gap between the first housing 10 and the second housing 20, the protective strip 22 absorbs the water and moisture, reducing the amount of water and moisture entering the interior through the gap between the first housing 10 and the second housing 20, thereby improving the reliability of waterproofing and moisture protection. When the protective strip 22 in the groove 21 needs to be replaced after becoming damp, the end of the protective strip 22 away from the housing 30 is pulled outward through the through hole 23, causing the protective strip 22 to slide outward along the groove 21 and the through hole 23, so that the part of the protective strip 22 located inside the housing 30 moves into the groove 21. This process replenishes the portion of the protective strip 22 that has been pulled out. Since this process does not require disassembling and opening the first housing 10 and the second housing 20, the protective strip 22 in the groove 21 can be replaced, thereby improving the convenience of waterproofing and moisture protection. After the protective strip 22 is pulled out, the cutter 41 slides along the second housing 20 to cut the protective strip 22, improving the convenience of replacing the protective strip 22. At the same time, the cutter 41 also blocks the outside of the through hole 23, so that the through hole 23 is not connected to the outside of the second housing 20, preventing the protective strip 22 from moving outward and detaching from the second housing 20, thus improving convenience.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, a knife groove 51 is provided on the second housing 20. The knife groove 51 is located below the cutter 41, and the knife groove 51 and the cutter 41 slide in a vertical direction.

[0034] It should be noted that the blade groove 51 is a recessed groove used to accommodate the lower end of the cutter 41.

[0035] In this embodiment, the groove 51 cooperates with the cutter 41 to limit the cutter 41 and the second housing 20, thereby improving the stability of the cutter 41 when it blocks the outside of the through hole 23.

[0036] like Figure 3 and Figure 4 As shown, the cutter 41 has a groove 52, and the second housing 20 is fixedly connected to a slide bar 53. The groove 52 and the slide bar 53 slide together in the vertical direction.

[0037] It should be noted that the cross-sectional shape of the groove 52 and the slider 53 is dovetail-shaped.

[0038] In this embodiment, the groove 52 cooperates with the slide bar 53 to make the process of the cutter 41 sliding along the second housing 20 more stable.

[0039] like Figure 4 As shown, the lower end of the cutter 41 is designed to be angled.

[0040] It should be noted that the cutting edge of the cutter 41 is located at the lower end of the cutter 41.

[0041] In this embodiment, the inclined design of the cutter 41 increases the cutting force at the lower end of the cutter 41, making it easier for the cutter 41 to cut the protective strip 22.

[0042] like Figure 1 and Figure 2 As shown, the housing 30 includes a fixed shell 54 fixedly connected to the second housing 20. The fixed shell 54 is rotatably connected to the rotating shaft 31, and a cover plate 55 is detachably connected to one side of the fixed shell 54.

[0043] It should be noted that the fixed shell 54 and the cover plate 55 are detachably connected together by bolts (not shown in the figure).

[0044] In this embodiment, when it is necessary to replenish the protective strip 22 in the housing 30, the cover plate 55 is removed from the fixed housing 54 to facilitate the replenishment of the protective strip 22. The cover plate 55 is installed on the fixed housing 54 to prevent external water and moisture from entering the housing 30, thereby reducing the possibility of the protective strip 22 becoming damp inside the housing 30.

[0045] like Figure 1 As shown, an observation window 56 is provided on the cover plate 55, and the observation window 56 is fixedly connected to the housing 30.

[0046] It should be noted that the observation window 56 is made of transparent material.

[0047] In this embodiment, the observation window 56 allows the operator to observe the wear status of the protective strip 22 in the housing 30 from the outside, facilitating the replacement of the protective strip 22.

[0048] The working principle of this utility model is as follows: the protective strip 22 absorbs water and moisture entering from the outside into the gap between the first housing 10 and the second housing 20, thereby improving the reliability of waterproofing and moisture protection. When replacing the protective strip 22, only one end of the protective strip 22 needs to be pulled out, and the part of the protective strip 22 located inside the housing 30 moves into the groove 21. There is no need to disassemble the first housing 10 and the second housing 20, which improves convenience. At the same time, the cutter 41 cuts the pulled-out protective strip 22 and blocks the outside of the through hole 23, preventing the protective strip 22 from moving outward and detaching from the second housing 20.

[0049] 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 principles 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.
