Description

Technical Field

[0001] This utility model relates to the field of lightning protection and monitoring technology, and in particular to a rainproof device, a monitoring device, and a lightning protection monitoring component. Background Technology

[0002] In power systems, lightning arrester monitors are crucial devices for protecting outdoor power generation equipment, such as transformers, from electrical disasters caused by lightning strikes. Since lightning arrester monitors are installed outdoors, rain protection is essential. Furthermore, they are typically installed at a certain height, making on-site observation difficult. In extreme weather conditions, such as thunderstorms and heavy rain, it is even more challenging for personnel to monitor the monitors' operational status in real time. To address these issues, we propose a rainproof device, a monitoring device, and lightning arrester monitor components, taking into account actual site conditions.

[0003] A search revealed Chinese patent document CN216560749U, published on May 17, 2022, which discloses a rainproof lightning protection counter device. The device includes a lightning protection counter and a rainproof cover. Two through holes at the bottom of the lightning protection counter correspond to two through holes in a bracket inside the rainproof cover, and are fixedly connected by screws and nuts. The rainproof cover is a scoop-shaped cuboid with openings at the front and bottom, and its upper panel is inclined towards the openings. The bracket inside the rainproof cover is located at the bottom of the cover body and is fixedly connected to it. Its advantages are: by installing the rainproof cover, the defect rate of the lightning protection counter is reduced, thus reducing the consumption of manpower, materials, and equipment due to defects. Its disadvantages are: because the lightning protection counter is installed inside the rainproof cover, a large space is required to accommodate the cover. When space is limited, the rainproof cover cannot be installed, or modifications to the site are necessary, making it inconvenient to use. Utility Model Content

[0036] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0037] Example 1:

[0038] Because the observation window at the front end of the lightning protection monitor 1 is made of glass, while the casing of the lightning protection monitor 1 is made of metal, after a period of use exposed to sun and rain, water can easily seep through the gap between the glass and the casing, causing the lightning protection monitor 1 to become damp.

[0039] Therefore, see Figure 1-4 We propose a rainproof device, including a mounting ring 10 and a rain cover 20. The rain cover 20 is fixed to one side of the mounting ring 10. The mounting ring 10 is used to install and fix it to the lightning protection monitor 1, and the rain cover 20 is used to cover the observation window at the front end of the lightning protection monitor 1.

[0040] In this embodiment, see Figure 1 , 2 The mounting ring 10 is installed and fixed onto the lightning protection monitor 1. The rain cover 20 covers the observation window at the front of the lightning protection monitor 1. The rain protection device occupies the space in front of the lightning protection monitor 1. Since the lightning protection monitor needs to be observed, the space in front of the lightning protection monitor is not obstructed, making the installation more convenient.

[0041] In this embodiment, see Figure 3 The rain cover 20 has a C-shaped arc structure.

[0042] Of course, the rain cover 20 can also have a C-shaped structure with folded corners on both sides, similar to a door frame.

[0043] See Figure 3 The mounting ring 10 includes a ring body 11 with a break 12. The ring body 11 has outwardly extending ear plates 13 at both ends of the break 12. Through holes are provided on the ear plates 13 on both sides, and clamping bolts 14 connect the ear plates 13 through these through holes. This structure forms a clamping structure for the mounting ring 10, allowing for a tighter fixation to the lightning arrester 1.

[0044] During installation, in order to prevent water from seeping through the gap between the mounting ring 10 and the lightning protection monitor 1, sealant can be filled between the mounting ring 10 and the lightning protection monitor 1 to seal the gap between the mounting ring 10 and the lightning protection monitor 1 and the disconnection 12.

[0045] Example 2:

[0046] Based on Embodiment 1, this embodiment proposes a monitoring device that installs a camera assembly 30 inside the rain cover 20 to observe the lightning protection monitor 1 in real time.

[0047] Specifically, see Figures 1 to 7 A mounting base 21 is provided on the upper side inside the rain cover 20. The mounting base 21 is used to install the camera assembly 30, which is located in front of the observation window of the lightning protection monitor 1.

[0048] Mounting base 21 provides a mounting position for mounting camera assembly 30. Mounting base 21 has a certain thickness to facilitate screw connection and fixation between camera assembly 30 and mounting base 21.

[0049] This invention enables real-time monitoring of the lightning arrester 1 by installing a camera assembly 30 inside the rain cover 20. Furthermore, as... Figure 1 , 2 As shown in Figure 4, when this installation method is adopted, the camera assembly 30 is located in front of the lightning protection monitor 1 at a slightly higher position. Therefore, after the camera assembly 30 is installed, it will not obstruct the staff from observing the lightning protection monitor 1 from the ground.

[0050] In this embodiment, see Figure 6 , 7 The camera assembly 30 includes a camera 31, and brackets 32 are mounted on both sides of the camera 31 via adjusting screws 33. The brackets 32 are connected to the mounting base 21 via mounting screws 34. This structure facilitates the adjustment of the angle of the camera 31.

[0051] Specifically, the bracket 32 ​​has a door frame structure. The side walls on both sides of the bracket 32 ​​are connected to the two sides of the camera 31 by adjusting screws 33. When the adjusting screws 33 are loose, the angle of the camera 31 can be adjusted. After adjustment, the adjusting screws 33 are tightened.

[0052] To facilitate nighttime observation, camera 31 can be equipped with night vision or have LED lights installed on the front of camera 31.

[0053] Furthermore, to facilitate the installation of the camera assembly 30 as needed, and to allow adjustment of the position of the camera assembly 30 after installation so that the monitoring image is centered on the monitor, see [link to relevant documentation]. Figure 3 , 4 5. A sliding groove 23 is symmetrically arranged on the upper side inside the rain cover 20. The mounting base 21 is slidably installed in the sliding groove 23. A limit screw 24 is screwed onto the mounting base 21. When the limit screw 24 abuts against the inner wall of the rain cover 20, it limits the mounting base 21.

[0054] When the camera assembly 30 is not required in certain locations, the mounting base 21 can be omitted. If the camera assembly 30 needs to be installed, the mounting base 21 with the camera assembly 30 installed can be inserted into the slide groove 23 and then fixed in place by the limiting screw 24. See also Figure 5 When the limit screw 24 is tightened and abuts against the inner wall of the rain cover 20, the mounting base 21 will be limited.

[0055] In this embodiment, see Figure 5 The upper side of the rain cover 20 is symmetrically provided with raised strips 22, and a groove 23 is formed between the raised strips 22 and the rain cover 20.

[0056] See Figure 7 The mounting base 21 includes a slider 211, and sliders 212 are provided on both sides of the slider 211. The sliders 212 on both sides slide in the slider grooves 23 on both sides respectively. The limiting screw 24 is screwed onto the slider 211. The camera assembly 30 is mounted on the lower side of the slider 211 by mounting screw 34.

[0057] Furthermore, a wire clip 40 is installed on the outside of the rain cover 20 by screws, and the wire clip 40 is used to fix the cable 35 of the camera assembly 30.

[0058] Specifically, see Figure 8 , 9 The wire clamp 40 includes a pressure plate 41, with a mounting hole 42 at each end. A raised ring 43 is located in the middle of the pressure plate 41, and a groove 44 is formed inside the raised ring 43. The inner diameter of the groove 44 is slightly smaller than the outer diameter of the cable 35. The wire clamp 40 is mounted on the outside of the rain cover 20 using screws. One or multiple wire clamps 40 can be installed as needed.

[0059] Example 3:

[0060] Based on Embodiment 2, this embodiment proposes a lightning protection monitoring component, which is a lightning protection monitoring device 1 on which the above-mentioned monitoring device is installed.
