Technical Field
[0001] The present application relates to the technical field of shock-absorbing hammers, and in particular to a shock-absorbing hammer failure monitoring and early warning device. Background Art
[0002] Overhead lines, especially high-voltage lines, are prone to vibration from natural forces like wind due to their high pole positions and large spans. This vibration can lead to fatigue damage. As a crucial piece of protective hardware, shock absorbers, through their shock-absorbing properties, can quickly respond to vibrations caused by natural disasters like wind and earthquakes. This helps maintain line stability, minimize damage to poles and cables, and extend the line's service life, playing a key role in the safe operation of overhead lines.
[0003] However, during the production and operation of the power grid, as time goes by, the shock absorber is exposed to harsh environments for a long time, such as high temperature, low temperature, humidity, corrosion, etc. After long-term use, the shock absorber may shift or fall off due to reasons such as material aging, resulting in the inability to effectively suppress line vibration, thereby posing a safety hazard. Therefore, a shock absorber failure monitoring and early warning device is proposed to solve the above technical problems. Utility Model Content

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.
[0024] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0025] One of the preferred embodiments of this application is as follows: Figures 1 to 6 As shown, a shock-proof hammer failure monitoring and early warning device includes a shock-proof hammer 3, an alarm device 7, a switch assembly 8 and a trigger assembly 4. The shock-proof hammer 3 is installed on the wire 2, the alarm device 7 is installed on the shock-proof hammer 3, the switch assembly 8 is installed on the shock-proof hammer 3 and is electrically connected to the alarm device 7, and the trigger assembly 4 is installed on the shock-proof hammer 3 and cooperates with the switch assembly 8.
[0026] It can be understood that when the shock-absorbing hammer 3 falls off and shifts, the faulty shock-absorbing hammer 3 will act on the switch assembly 8 through the trigger assembly 4, thereby causing the switch assembly 8 to change from an open state to a closed state, and then the alarm device 7 is driven and an alarm is issued, thereby reminding maintenance personnel to conduct inspections and repairs in a timely manner.
[0027] It can be seen that when the shock-proof hammer 3 fails, the alarm information can be sent to the maintenance personnel in time through the alarm device 7, so that the conductor 2 can be prevented from generating long-term excessive vibration due to the loss of the function of the shock-proof hammer 3, thereby ensuring the safe operation of the overhead line and further avoiding the expansion of losses.
[0028] It should be noted that the falling off of the shock-absorbing hammer 3 refers to the falling off of the hammer body 301 of the shock-absorbing hammer 3 , and the displacement of the shock-absorbing hammer 3 refers to the displacement of the position of the shock-absorbing hammer 3 on the conductor 2 .
[0029] As a further description of the above embodiment: the trigger assembly 4 includes a lower shell 401, a pair of lower sliders 403 and a pair of lower rope bodies 402. The lower shell 401 is installed at the lower end of the shock-absorbing hammer 3. The lower sliders 403 are installed on both sides of the interior of the lower shell 401 through spring elastic horizontal sliding. The two ends of the lower rope body 402 are respectively connected to the lower sliders 403 and the hammer body 301 of the shock-absorbing hammer 3.
[0030] like Figure 3 As shown, in the normal state: the lower slider 403 and the switch assembly 8 are far away from each other, and the lower rope 402 has a certain redundancy, that is, the hammer 301 will not pull the lower slider 403 through the lower rope 402 under normal vibration. Figure 4 As shown, the downward-moving shock-absorbing hammer 3 will pull the lower slider 403 to move through the lower rope body 402. When the lower slider 403 moves to the extreme position, it will squeeze the switch assembly 8, thereby triggering the switch assembly 8 to start the alarm device 7.
[0031] It should be noted that the hammer body 301 is located on the left and right sides of the shock-absorbing hammer 3, while the lower housing 401 is installed in the middle of the shock-absorbing hammer 3. Therefore, the lower rope body 402 is tilted, while the lower slider 403 connected to the lower rope body 402 is arranged horizontally. This oblique tension will reduce the service life of the lower rope body 402. Therefore, L-shaped guide sleeves 6 are provided on the exterior of both sides of the lower housing 401. The lower rope body 402 passes through the guide sleeves 6. As is known, the L-shaped guide sleeves 6 have two horizontal and vertical parts. Therefore, the guide sleeves 6 can divide the lower rope body 402 into a horizontal section and a vertical section. The horizontal section is connected to the lower slider 403, while the vertical section is connected to the hammer body 301. This effectively prevents the lower rope body 402 from wear and breakage caused by excessive oblique tension during use. At the same time, the guide sleeves 6 also serve as a limit guide for the lower rope body 402 and better pull the lower slider 403, thereby extending the overall service life of the trigger assembly 4.
[0032] Further, such as Figure 5 As shown, the trigger assembly 4 also includes an upper shell 405, an upper slider 406 and an upper rope body 404. The upper shell 405 is installed on the upper end of the shock-absorbing hammer 3. The upper slider 406 is installed inside the upper shell 405 through a spring vertical elastic sliding. The bottom end of the upper rope body 404 is connected to the upper slider 406, and the top end of the upper rope body 404 passes through the upper shell 405 and is connected to the mounting tower 1 of the wire 2.
[0033] It can be understood that when the shock-absorbing hammer 3 shifts, since the top of the upper rope body 404 is fixed, the upper slider 406 is equivalent to being pulled by the upper rope body 404. When the upper slider 406 moves to the extreme position, the upper slider 406 will trigger the switch assembly 8 and activate the alarm device 7.
[0034] It should be noted that the installation position of the shock-absorbing hammer 3 is generally located near the connection point between the conductor 2 and the tower 1, such as Figure 1 As shown, if the top end of the upper rope 404 is directly connected to the iron tower 1, the upper rope 404 is also in an inclined state. Moreover, only when the shock-absorbing hammer 3 is displaced away from the iron tower 1 can it play the role of pulling the upper slider 406; if the shock-absorbing hammer 3 is displaced toward the direction close to the iron tower 1, the upper slider 406 cannot be moved and the alarm device 7 cannot be triggered.
[0035] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Figure 1 As shown, the upper rope body 404 can be installed on the iron tower 1 through the bracket 5, that is, the upper rope body 404 can be vertically installed on the upper slider 406 through the bracket 5, that is, the upper rope body 404 is in a vertical state.
[0036] It is understandable that if Figure 6 As shown, assuming that the shock-absorbing hammer 3 is located at position A of the wire 2 (this is the installation position), in the later use process, the shock-absorbing hammer 3 may be displaced due to the shaking of the wire 2. Of course, it may move to the left or to the right. When it moves to the extreme position to the left, it is A1, and when it moves to the extreme position to the right, it is A2. When it moves to the extreme distance, the upper slider 406 will move up to the extreme distance and trigger the alarm device 7; when the shock-absorbing hammer 3 moves between A1 and A2, the rotation angle of the upper rope body 404 is θ.
[0037] Specifically, the following configuration can be employed: when the shock-absorbing hammer 3 moves between A1 and A2, this is considered the displacement error of the shock-absorbing hammer 3. In other words, at this time, the shock-absorbing hammer 3 can still provide a shock-absorbing effect on the conductor 2. Furthermore, the upper rope 404 is sufficiently strong, for example, a steel wire rope can be used, thereby limiting the position of the shock-absorbing hammer 3 so that it can only move between A1 and A2. When the shock-absorbing hammer 3 reaches its limit position, it indicates that the position of the shock-absorbing hammer 3 needs to be corrected, thereby triggering the alarm device 7 to promptly notify maintenance personnel.
[0038] Of course, the lower rope body 402 can also be made of a rope with better strength, such as a nylon rope or a steel wire rope. When the hammer body 301 falls off, the lower rope body 402 can also limit the hammer body 301, preventing the hammer body 301 from completely separating from the shock-absorbing hammer 3, thereby avoiding the hammer body 301 from causing damage to surrounding facilities.
[0039] In this embodiment, Figure 3 as well as Figure 5 As shown, the switch assembly 8 includes three sets of normally open switches 801. Two sets of normally open switches 801 are installed on both sides of the lower housing 401, corresponding to the two lower sliders 403. Another set of normally open switches 801 is installed on the top inner wall of the upper housing 405, corresponding to the upper slider 406. In other words, whether either of the two hammer bodies 301 falls off or the anti-vibration hammer 3 shifts, the normally open switches 801 can trigger the alarm device 7.
[0040] Specifically, the alarm device 7 includes a battery module 702 and an early warning circuit board 701, both of which can be installed inside the lower shell 401. The early warning circuit board 701 is electrically connected to the switch assembly 8 (i.e., three groups of normally open switches 801), and the battery module 702 is suitable for powering the early warning circuit board 701.
[0041] It can be understood that under normal conditions, the normally open switch 801 is in the open state. When the shock-absorbing hammer 3 fails, the corresponding slider will move and squeeze the normally open switch 801, thereby triggering and closing the normally open switch 801. At this time, the early warning circuit board 701 will receive a fault signal, which will be sent to the ground monitoring center through the wireless transmission module, thereby realizing remote monitoring and early warning of the failure of the shock-absorbing hammer 3.
[0042] Furthermore, in order to solve the battery life problem of the battery module 702, a solar panel can be provided on the outside of the upper shell 405 or the lower shell 401, and the solar panel is connected to the battery module 702, thereby providing an additional charging function for the battery module 702 to ensure long-term continuous operation of the alarm device 7.
