Description

Technical Field

[0001] The present application relates to the technical field of electric power equipment, and in particular to a mounting bracket for monitoring ice coating and ice melting of power transmission lines. Background Art

[0002] Low temperatures and severe cold weather are very harmful to power transmission lines. For example, in areas prone to ice and snow, power transmission lines may be covered with ice, which will pose a serious threat to the power system and lead to accidents such as line breakage and tower collapse. Traditional ice observation methods mostly rely on manual inspections or non-automated monitoring equipment, which cannot achieve fast and accurate ice observation and early warning.

[0003] In the related art, a Chinese patent with announcement number CN219554554U proposes a contact network ice-covering monitoring and de-icing device, which includes a column, a wrist arm is arranged on the column, the other end of the wrist arm is connected to the column through an inclined rod, a positioning frame is arranged below the wrist arm, a mechanical sensor is arranged at the proximal end of the connection between the wrist arm and the column, and a monitoring component for monitoring the appearance of the contact network is also arranged on the column, and the monitoring component is arranged above the wrist arm. The monitoring component is connected to the column through a bracket, and includes a micro-meteorological detection unit, a capacitive frost sensor and an image monitoring module, and the monitoring end of the image monitoring module is arranged facing the contact network.

[0004] The above-mentioned related technologies have the following defects: the monitoring component is stably installed on the column at a fixed angle through a bracket, so that the monitoring component can stably monitor the ice and ice melting conditions of the contact network. Since the monitoring component includes an image monitoring module, considering the clarity and integrity of the image presentation, it is necessary to design a bracket suitable for the distribution of different contact networks to ensure that the monitoring component can stably monitor the ice and ice melting conditions of the contact network when it is installed on the column through the bracket. If there is a slight error in the design of the bracket, the monitoring component cannot be quickly installed at a suitable angle, thereby affecting the monitoring effect of the monitoring component on the contact network.

DETAILED DESCRIPTION

[0024] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0025] The present application embodiment discloses a mounting bracket for monitoring ice and ice melting of a transmission line, which is mounted on an electric tower 1, referring to Figure 1 and Figure 2A mounting bracket for monitoring ice and ice melting of a transmission line includes a fixed plate 2 fixedly connected to an electric tower 1, a rotating plate 3 located at one side of the electric tower 1 and rotatably mounted on the fixed plate 2, and a locking assembly for locking and fixing the rotating plate 3 on the fixed plate 2; the fixed plate 2 and the rotating plate 3 are both made of steel and are bent into an L shape, one side of the fixed plate 2 is stably mounted on the electric tower 1 by screws, and the other side is vertically arranged on one side of the electric tower 1; one side of the rotating plate 3 is rotatably fitted on the vertical side of the fixed plate 2, and the other rotating plate 3 is arranged perpendicular to the vertical side of the fixed plate 2. The rotating plate 3 is equipped with a monitoring mechanism 4 for monitoring the ice and ice melting conditions of the transmission line. The monitoring mechanism 4 includes a photoelectric ice detection sensor, a weather radar, an atmospheric wind speed sensor, and a temperature and humidity sensor. The monitoring mechanism 4 is stably installed on the side of the rotating plate 3 perpendicular to the vertical side of the fixed plate 2. By driving the rotating plate 3 to rotate on the fixed plate 2, the installation angle of the monitoring mechanism 4 can be quickly adjusted, so that the monitoring mechanism 4 can better monitor the ice and ice melting conditions on the transmission line. The locking assembly can quickly lock and fix the rotating plate 3 with the adjusted angle on the fixed plate 2 to ensure that the monitoring mechanism 4 can stably monitor the ice and ice melting conditions of the transmission line.

[0026] To achieve rapid locking of the rotating plate 3, refer to Figure 2 , Figure 3 and Figure 4 , the fixed plate 2 is provided with a plurality of positioning holes 6, which are circumferentially distributed along the axis of the rotating shaft of the rotating plate 3; correspondingly, the rotating plate 3 is also provided with a plurality of arc-shaped through holes 7, and a plurality of locking assemblies are also provided, and the plurality of arc-shaped through holes 7, the plurality of locking assemblies and the plurality of positioning holes 6 correspond one to one, and the center of the circle formed by the plurality of arc-shaped through holes 7 is located on the axis of the rotating shaft of the rotating plate 3. Considering the convenience of operation and the stability of locking the rotating plate 3, three locking assemblies, positioning holes 6 and arc-shaped through holes 7 are provided.

[0027] Reference Figure 2 , Figure 3 and Figure 4The locking assembly includes a positioning rod 51 which is penetrated by an arc-shaped through hole 7 and a positioning hole 6 in sequence, a pressing block 52 fixed on one end of the positioning rod 51 and used to press the rotating plate 3 against the fixed plate 2, and a locking structure used to lock the positioning rod 51 on the fixed plate 2, and the locking structure is located between the fixed plate 2 and the positioning rod 51. In the embodiment of the present application, the locking structure includes a fixing cylinder 53 installed at the positioning hole 6 on the fixed plate 2 and an elastic telescopic rod 54 telescopically arranged on the positioning rod 51; the fixing cylinder 53 is coaxially arranged with the positioning hole 6, and two telescopic rods 54 are arranged, and the two telescopic rods 54 are respectively located on both sides of the positioning rod 51, and the telescopic rods 54 are telescopically arranged along the radial direction of the positioning rod 51. When the rotating plate 3 needs to be locked on the fixed plate 2, the telescopic rod 54 can be compressed first, and then the positioning rod 51 can drive the telescopic rod 54 to pass through the arc-shaped through hole 7, the positioning hole 6 and the fixed cylinder 53 in sequence. When the pressing block 52 presses the rotating plate 3 against the fixed plate 2, the telescopic rod 54 is no longer pressed. At this time, the telescopic rod 54 is located at the end of the fixed cylinder 53 away from the rotating plate 3 and abuts against the end of the fixed cylinder 53, so that the movement of the positioning rod 51 along the depth direction of the positioning hole 6 is restricted, and the rotating plate 3 can also be stably pressed and fixed on the fixed plate 2 by the pressing block 52, thereby completing the rapid locking and fixing of the rotating plate 3. In other embodiments, the locking structure is a thread set on the outer wall of the positioning rod 51 and the inner wall of the positioning hole 6. By rotating the positioning rod 51, the positioning rod 51 drives the pressing block 52 to push the rotating plate 3 to be pressed against the fixed plate 2 under the action of the thread on the inner wall of the positioning hole 6, thereby completing the locking and fixing of the rotating plate 3.

[0028] In order to further improve the clamping effect on the rotating plate 3, an anti-skid pad is provided on the side of the clamping block 52 close to the positioning rod 51. The anti-skid pad can be a rubber pad or a damping pad. The anti-skid pad has a large friction coefficient, so that the clamping block 52 can be stably pressed against the rotating plate 3 through the anti-skid pad, thereby achieving locking and fixation of the rotating plate 3.

[0029] In the embodiment of the present application, the rotating plate 3 is prevented from driving the positioning rod 51 to rotate in the positioning hole 6 through the pressing block 52, thereby affecting the locking stability of the rotating plate 3. Figure 3 and Figure 4The end of the fixed cylinder 53 is provided with a limiter 9 for limiting the deflection movement of the telescopic rod 54 at the end of the fixed cylinder 53. The limiter 9 can be a friction layer, such as a frosted layer, provided on the end of the fixed cylinder 53, or a damping ring or a rubber ring adhered to the end of the fixed cylinder 53, or a limiter groove provided on the end of the fixed cylinder 53. In the embodiment of the present application, the limiter 9 is two limiter grooves provided on the end of the fixed cylinder 53, and the two limiter grooves correspond to the two telescopic rods 54 one by one, so that when the pressing block 52 presses the rotating plate 3 on the fixed plate 2 through the anti-slip pad, the two telescopic rods 54 are respectively embedded in the two limiter grooves at the end of the fixed cylinder 53, limiting the rotation of the positioning rod 51 in the positioning hole 6, so that the pressing block 52 can stably lock the rotating plate 3 on the fixed plate 2 without rotating easily.

[0030] Considering the processing error, thermal expansion and contraction of the material, and the deformation of the pressing block 52 and the rotating plate 3 after long-term use, the pressing force of the pressing block 52 on the rotating plate 3 decreases, thereby affecting the stability of locking the rotating plate 3. Figure 3 and Figure 4 , an internal threaded tube 8 is fixed on the fixed plate 2 at the positioning hole 6, the internal threaded tube 8 is located on the side of the fixed plate 2 away from the rotating plate 3, and the internal threaded tube 8 is connected to the positioning hole 6. An external thread is arranged on the outer wall of the fixed tube 53, the fixed tube 53 is located at one end of the internal threaded tube 8 away from the fixed plate 2, and one end of the fixed tube 53 away from the stopper 9 is threadedly connected to the internal threaded tube 8. After the telescopic rod 54 is compressed, the positioning rod 51 can drive the telescopic rod 54 to pass through the arc through hole 7, the positioning hole 6, the internal threaded tube 8 and the fixed tube 53 in sequence. When it is necessary to increase the pressing force of the pressing block 52 on the rotating plate 3, the positioning tube can be driven to rotate in the internal threaded tube 8, so that the positioning tube moves in the direction away from the fixed plate 2, thereby increasing the distance from one end of the positioning tube with the stopper 9 to the fixed plate 2, so that when the telescopic rod 54 on the positioning rod 51 is pressed against the end of the positioning tube through the stopper 9, the pressing block 52 can press the rotating plate 3 against the fixed plate 2 with greater force.

[0031] The implementation principle of a mounting bracket for monitoring ice and de-icing of a power transmission line in the embodiment of the present application is as follows: first rotate the positioning cylinder, adjust the portion of the positioning cylinder extending out of the internal thread cylinder 8 to a suitable length, then align the three arc-shaped through holes 7 on the rotating plate 3 with the three positioning holes 6 on the fixed plate 2, and rotate the rotating plate 3 to a suitable angle. Then compress the telescopic rod 54, so that the positioning rod 51 can drive the telescopic rod 54 to pass through the arc-shaped through hole 7, the positioning hole 6, the internal thread cylinder 8 and the fixed cylinder 53 in sequence, until the telescopic rod 54 moves out of the fixed cylinder 53. Then, the telescopic rod 54 is no longer pressed, so that the telescopic rod 54 returns to its original length. At this time, the telescopic rod 54 is embedded in the limiting groove at the end of the fixed cylinder 53, so that the pressing block 52 can stably lock the rotating plate 3 on the fixed plate 2 through the anti-slip pad without rotating easily, thereby completing the rapid locking and fixing of the rotating plate 3. The monitoring mechanism 4 installed on the rotating plate 3 can be quickly positioned and installed to a suitable angle, so as to stably and accurately monitor the ice and de-icing conditions of the power transmission line.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
