Description

Technical Field

[0001] This application relates to the field of monitoring technology, and in particular to an online monitoring device for power transmission lines in low-light environments. Background Technology

[0002] With the development of the Internet and communication technologies, a wide variety of monitoring technologies for power transmission lines have emerged. However, in high-voltage power transmission line monitoring systems, video monitoring devices for power transmission lines, especially high-voltage power transmission lines and their auxiliary equipment, remain indispensable.

[0003] For example, Chinese patent application number CN202020918594.5 discloses an online monitoring device for power transmission lines in low-light environments, including a lower hemispherical transparent cover, a main shaft, a fisheye camera lens, a pair of short-focus and a pair of long-focus camera lenses, and a power module. The fisheye camera lens is fixed at the lowest end of the main shaft. The pair of short-focus and the pair of long-focus camera lenses are located above the fisheye camera lens, with one short-focus and one long-focus camera lens facing one direction of the power transmission line and the other short-focus and the other long-focus camera lens facing the other direction of the power transmission line. The transparent cover encloses the main shaft, the video image end of the fisheye lens, and the long-focus camera lens. The main shaft is located on the vertical line of the geometric center of the transparent cover. The sealing end of the cover plate and the main shaft is sealed with glue, and a bayonet is provided between the transparent cover and the cover plate, which is sealed with sealant.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Common online monitoring devices for power transmission lines are typically installed on external iron towers, where they are exposed to wind and sun for extended periods. The sealant between the cover plate and the main shaft, as well as between the transparent cover and the cover plate, is prone to aging and losing its sealing effect. This can lead to problems such as water seepage inside the transparent cover, resulting in high maintenance costs and a short service life. Utility Model Content

[0006] This application provides an online monitoring device for transmission lines in low-light environments to improve the following technical problems:

[0007] Common online monitoring devices for power transmission lines are exposed to wind and sun for extended periods, which can cause the sealant to age and lose its sealing effect.

[0031] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0032] This application discloses an online monitoring device for power transmission lines in low-light environments. (Refer to...) Figure 1 A low-light environment online monitoring device for power transmission lines includes a transparent cover 1 and a cover plate 2. The transparent cover 1 includes a hemispherical structure 11 at the bottom and a first cylindrical structure 12 at the top. A second cylindrical structure 21 is vertically arranged on the bottom periphery of the cover plate 2. The first cylindrical structure 12 and the second cylindrical structure 21 are detachably threaded together. A sealing ring 3 is also provided between the top of the transparent cover 1 and the lower surface of the cover plate 2. An external connection group 4 is integrally formed on the upper surface of the cover plate 2, and an internal mounting group 5 is integrally formed on the lower surface of the cover plate 2. The external connection group 4 is used to connect and fix an external iron tower, and the internal mounting group 5 is used to install and fix an internal camera group and lens. The external connection group 4 and the internal mounting group 5 are located on the central axis of the transparent cover 1.

[0033] To facilitate the installation and fixing of the sealing ring 3, a horizontally arranged support ring 13 is provided on the inner side of the top of the first cylindrical structure 12. The sealing ring 3 is sandwiched between the upper surface of the support ring 13 and the lower surface of the cover plate 2. That is, an annular groove adapted to the sealing ring 3 is provided on the upper surface of the support ring 13 or the lower surface of the cover plate 2.

[0034] To further reduce the risk of water seepage, the outer peripheral wall of the first cylindrical structure 12 is also provided with an inclined conical surface 121 and an external thread. An annular step is formed between the inclined conical surface 121 and the external thread, which abuts against the bottom of the second cylindrical structure 21. The annular step can further form a bent water-blocking surface on the bottom surface of the second cylindrical structure 21, effectively solving the problem of internal water seepage.

[0035] To prevent rainwater or dust from accumulating on the upper surface of the cover plate 2, the upper surface of the cover plate 2 is set as a conical surface 22, which is arranged downwards and outwards from the middle.

[0036] In this embodiment, the external connection assembly 4 includes a connecting plate 41 and multiple sets of bolt assemblies 42. The connecting plate 41 is arranged vertically, and the cover plate 2 is provided with vertically arranged oval holes 411. The multiple sets of bolt assemblies 42 are all installed in the oval holes 411. The two sides of the connecting plate 41 are vertically connected to the upper surface of the cover plate 2 by first reinforcing rib plates 43. The external connection assembly 4 designed above has a simple and robust structure, facilitates the connection of the entire device with the external iron tower, and the installation height can be adjusted to a certain extent.

[0037] In this embodiment, the internal mounting assembly 5 includes a mounting plate 51, which is arranged vertically and perpendicular to the connecting plate 41. The mounting plate 51 has multiple mounting holes for mounting cameras. Second reinforcing ribs 52 are vertically connected between the two sides of the mounting plate 51 and the lower surface of the cover plate 2. The internal mounting assembly 5 designed above is simple and robust, facilitating the installation and fixation of the internal camera and lens.

[0038] The beneficial technical effects of the online monitoring device for power transmission lines in low-light environments according to an embodiment of this application are roughly as follows:

[0039] The transparent cover 1 and the cover plate 2 are connected by adding a first cylindrical structure 12 and a second cylindrical structure 21 to achieve detachable threaded assembly. Unlike the common snap-fit ​​structure, the connection and sealing performance is higher. In addition, a sealing ring 3 is added to further improve the connection and sealing performance. Moreover, the external connection group 4 and the internal mounting group 5 are integrally formed and fixed to the cover plate 2, making the structure more robust. It does not require the use of sealant for sealing and the overall sealing performance is higher, which greatly reduces the risk of water leakage inside the transparent cover 1, reduces the later maintenance cost, and extends the service life.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
