Description

Technical Field

[0001] The present invention relates to the technical field of electric power detection with automatic wire retracting and releasing function, in particular to an electric power detection system with automatic wire retracting and releasing function. Background Art

[0002] In modern power systems, high-voltage transmission lines, as an important carrier of power transmission, undertake the key task of efficiently and safely transmitting electricity from power plants to various power consumption areas. However, with the continuous expansion and complexity of power networks, higher requirements are placed on the operation and maintenance management of transmission lines, especially for the voltage and power detection of high-altitude cables. This link is crucial because it is directly related to the stable operation and power supply reliability of the power system. Traditional cable detection methods mainly rely on manual inspections. Workers need to carry detection equipment and climb to the location of the high-altitude cables to perform operations. This method is not only inefficient, but also has high safety risks. The high-altitude working environment is complex, and workers face the dangers of falling, electric shock, etc. At the same time, the accuracy and consistency of manual detection are difficult to guarantee. In addition, the manual inspection cycle is long, and it is difficult to detect sudden failures or potential hidden dangers of cables in a timely manner, which may lead to power outages and cause huge losses to the social economy.

[0003] The existing Chinese patent with publication number CN117269847B includes a tester fixing plate and two connecting frames, wherein the tester fixing plate is located in the middle of the two connecting frames, and a fixed slot is provided inside the tester fixing plate, and a tester body is embedded in the interior of the tester fixing plate through the fixed slot, and the front and rear ends of the tester fixing plate are fixedly installed with a first movable sleeve, and a docking frame is welded on the upper end of the connecting frame, and two docking plug plates are inserted into the interior of the docking frame, and a moving wheel side plate is movably installed on the upper end of the docking plug plate, and a wire moving wheel is fixedly installed in the middle of the two moving wheel side plates, and the outer ring wheel sleeve is provided on the outside of the moving wheel side plate, and a moving wheel positioning structure is provided in the center of the docking frame.

[0004] When the above device is in use, when testing local electric wires, the wire moving wheels on both sides can be positioned and cannot move, and then the tester fixing plate slides around the center guide rod and the outside of the docking guide rod through the first moving sleeve to drive the tester body to move on the outside of the local area, which is more convenient for testing local electric wires and different positions. However, in actual use, there is a certain degree of slack in the installation of high-altitude cables. When facing strong winds, the cables shake, causing fluctuations in current and voltage. The lack of automated intervention measures affects the quality and stability of power detection and poses a threat to the safe operation of the power grid. Therefore, it is difficult to automatically tighten the cables when the current and voltage are unstable. Summary of the Invention

[0007] Preferably, the distance adjustment mechanism includes a support groove opened on one of the fixed frames, the inner wall of the support groove is connected to a U-shaped frame for lifting and moving, rectangular plates are fixedly connected at symmetrical positions at both ends of the U-shaped frame, positioning grooves for positioning and supporting the moving rod at the center position are opened at symmetrical positions of the two rectangular plates, inclined grooves for pulling the moving rods on both sides to move back and forth toward or away from each other are opened at symmetrical positions on both sides of each rectangular plate, and a movable block is fixedly connected to the corresponding position of each moving rod, and the end of each movable block away from the moving rod is respectively connected to the positioning groove and the inner wall of the inclined groove at the corresponding position.

[0008] Preferably, the end of the fixed frame close to one side of the U-shaped frame is penetrated and fixedly connected to a threaded rod driven to rotate by a power mechanism, and the U-shaped frame and the threaded rod are penetrated and fixedly connected at the corresponding position of the U-shaped frame and the threaded sleeve for the threaded rod to drive the U-shaped frame to move up and down and reciprocate, and the inner wall of the threaded sleeve is penetrated by the threaded rod and screwed.

[0009] Preferably, each of the fixed plates is provided with a movable groove, the inner wall of each movable groove is movably connected to an inverted T-shaped block for horizontal reciprocating movement, and the opposite surfaces of each two adjacent inverted T-shaped blocks are fixedly connected to connecting blocks.

[0010] Preferably, each of the connecting blocks is coaxially connected to an adjusting rod that pulls the inverted T-shaped block to move horizontally back and forth, and each adjacent two fixed plates are fixedly connected to opposite surfaces on both sides with a fixed seat, and each adjacent two adjusting rods are connected to the fixed seat on the adjacent side on one end away from the connecting block for fixed-axis rotation.

[0011] Preferably, the retracting and extending mechanism includes guide grooves provided at symmetrical positions on both sides of each fixed plate, the inner walls of the guide grooves on both sides near one end of the inverted T-shaped block are penetrated and movably connected to movable rods, and the ends of the movable rods on both sides are fixedly connected to clamping blocks for clamping and fixing the cables.

[0012] Preferably, each of the inverted T-shaped blocks is provided with a limiting groove at a symmetrical position close to the movable rods on both sides, and the bottom ends of the movable rods on both sides respectively penetrate the inner wall of the limiting groove on the adjacent side and are horizontally movable and connected.

[0013] Preferably, each of the fixed plates is fixedly connected to a support frame at one end close to the movable rod, and the opposite surfaces at both ends of each support frame are penetrated and connected to a winding roller for winding and releasing the cable in a fixed axis rotation, and the opposite surfaces at both ends of each winding roller and the support frame are fixedly connected to a torsion spring for guiding the winding roller to reset and rotate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the detection device body at the top of the inverted U-shaped frame and equipping it with multiple jaws to directly clamp the cable, real-time and accurate detection of cable current and voltage can be achieved. The detection equipment converts the collected current and voltage signals into electrical signals, and remotely transmits and analyzes the data through an external controller, allowing staff to monitor the operating status of the cable in real time at the control center, improving detection efficiency and avoiding the inefficiency and errors of traditional manual detection. It can also promptly detect abnormal conditions of the cable, such as current and voltage fluctuations, short circuits, etc., so as to quickly respond and take measures to effectively prevent the occurrence of power failures and ensure the stable operation of the power system.

[0015] 2. Through the distance adjustment mechanism, the distance between cables can be automatically adjusted under severe weather conditions such as strong winds. When the detection equipment body detects abnormal cable current, the distance adjustment mechanism will drive the U-shaped frame to rise and fall through the cooperation of the threaded rod and the threaded sleeve block, thereby pulling the moving rods on both sides to move oppositely through the inclined groove and the movable block, increasing the distance between the cables, avoiding collision or short circuit due to shaking of the cables, improving the safety and accuracy of the power detection system, and reducing the current and voltage fluctuation problems caused by poor cable contact or short circuit.

[0016] 3. The retractable mechanism can automatically tighten and release the cable according to the signal of the detection equipment. In windy weather, the cable is prone to shaking, resulting in unstable current and voltage. The distance adjustment mechanism increases the distance between the cables. Through the cooperation of the clamping block and the movable rod, the retractable mechanism can tighten the cable and reduce the shaking amplitude. At the same time, the design of the support wheel can reduce the friction between the cable and the support device, further extend the service life of the cable, improve the accuracy of power detection, and enhance the stability of the power system.

[0017] 4. The force of cable shaking is buffered by the winding roller and torsion spring on the support frame. In the initial state, the torsion spring is in a semi-reeled state. When the cable is shaken by strong wind, the torsion spring drives the winding roller to rotate to buffer the shaking force of the cable. At the same time, when the cable is tightened, the winding roller can retract excess cable under the action of the torsion spring, and when the cable is reset, the torsion spring can drive the winding roller to return to the semi-reeled state, which not only reduces the shaking amplitude of the cable, but also protects the cable from excessive stretching or wear, thereby extending the service life of the cable.

[0018] The coordinated use of the above-mentioned structure solves the problem that existing high-altitude cables have a certain degree of slack during the installation process. When facing strong winds, the cables shake, causing fluctuations in current and voltage. The lack of automated intervention measures affects the quality and stability of power detection and poses a threat to the safe operation of the power grid. Therefore, it is difficult to automatically tighten the cables when the current and voltage are unstable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figures 1 to 10 The present invention provides a technical solution: an electric power detection system with an automatic wire retracting and releasing function, comprising an inverted U-shaped frame 1, wherein both ends of the inverted U-shaped frame 1 are fixedly connected to a fixing frame 2 for fixing and supporting the inverted U-shaped frame 1 on the top of the power tower, and the inverted U-shaped frame 1 is fixedly connected to a track rod 3 at symmetrical positions on both sides, and the track rod 3 on each side is horizontally connected to a plurality of evenly placed moving rods 4, and the moving rods 4 on both sides are provided with through holes 401 for positioning and supporting the cables at symmetrical positions near the bottom end, and each of the moving rods 4 is provided with a through hole 401 for positioning and supporting the cables. The bottom end of the rod 4 is fixedly connected to a fixed plate 5, and each of the fixed plates 5 is connected to a support wheel 6 for rolling support on the outer contour of the cable on a fixed axis rotation at one end away from the moving rod 4. The top of the inverted U-shaped frame 1 is penetrated and fixedly connected to a detection device body 7 for detecting the power and voltage of the cable, and the detection device body 7 communicates with the external controller through signals. The detection device body 7 is provided with a plurality of jaws 8 for clamping on the cable, and the fixed frame 2 is provided with a distance adjustment mechanism for adjusting the cable spacing and a retracting mechanism for tightening the cable.

[0024] When in use, by setting the inverted U-shaped frame 1 and the fixing frame 2 provided on the inverted U-shaped frame 1, the inverted U-shaped frame 1 can be fixedly supported on the fixing frame 2, and the fixing frame 2 is fixedly supported on the top of the power tower by bolts, thereby improving the stability of the inverted U-shaped frame 1 and the fixing frame 2. By setting the track rod 3 on the inverted U-shaped frame 1, the track rod 3 can be fixedly supported on the inverted U-shaped frame 1, and the moving rod 4 provided on the track rod 3 supports the moving rod 4, so that the moving rod 4 can be horizontally moved and connected on the outer contour of the track rod 3, such as Figure 1 As shown, three groups of movable rods 4 are arranged on both sides of the inverted U-shaped frame 1, and the through holes 401 are opened on the movable rods 4. First, multiple cables are respectively passed through the inner walls of the through holes 401 at symmetrical positions on both sides, so that the through holes 401 can respectively position and support multiple cables, ensuring the stability of the cables, and avoiding the problem of multiple cables shaking and entangled together in bad weather with strong winds. The fixing plate 5 is arranged on the movable rod 4, and the fixing plate 5 is fixedly supported on the bottom end of the movable rod 4. The cable can be movably supported in the groove of the outer contour of the support wheel 6 through the support wheel 6 arranged on the fixing plate 5.

[0025] By means of the detection device body 7 provided on the inverted U-shaped frame 1, the detection device body 7 can be fixedly supported on the inverted U-shaped frame 1, and the jaws 8 provided on the detection device body 7 first clamp the jaws 8 on the cables respectively. When current passes through the cables, an induced current is generated in the jaws 8, and the detection device body 7 is connected with the external controller through a signal, so that the detection device body 7 can convert the detected current into an electrical signal and transmit it remotely to the external controller. At the same time, the external controller can process the voltage signal and finally display the magnitude of the current, so that the staff can remotely monitor the current of the cable in real time through the external controller. The above-mentioned detection device body 7 can convert the detected current into an electrical signal and transmit it remotely to the external controller, which is a prior art content well known to people in this field, so it will not be repeated here.

[0026] By means of the distance adjusting mechanism and the retracting mechanism provided on the fixing frame 2, the distance adjusting mechanism can adjust the spacing between multiple cables, while the retracting mechanism can tighten and release the cables, and the support wheel 6 is connected to the fixing plate 5 for fixed-axis rotation. As the retracting mechanism tightens and releases the cables, the support wheel 6 rotates back and forth under the movement of the cables, thereby reducing friction on the cables and extending the service life of the cables.

[0027] Example 2:

[0028] On the basis of the first embodiment, further steps are as follows: The distance adjustment mechanism includes a support groove 201 opened on one of the fixed frames 2, and the inner wall of the support groove 201 is connected to a U-shaped frame 9 for lifting and moving. Rectangular plates 12 are fixedly connected at symmetrical positions at both ends of the U-shaped frame 9, and positioning grooves 121 for positioning and supporting the moving rod 4 at the center position are opened at symmetrical positions of the two rectangular plates 12. Inclined grooves 122 for pulling the moving rods 4 on both sides to move back and forth toward or away from each other are opened at symmetrical positions on both sides of each rectangular plate 12, and a movable block 13 is fixedly connected to the corresponding position of each moving rod 4, and each end of the movable block 13 away from the moving rod 4 is respectively connected to the inner walls of the positioning groove 121 and the inclined groove 122 at the corresponding position.

[0029] The end of the fixed frame 2 near the U-shaped frame 9 is penetrated and connected to a threaded rod 10 driven by a power mechanism for rotation. The U-shaped frame 9 and the threaded rod 10 are penetrated and fixedly connected at the corresponding position of the U-shaped frame 9 and the threaded rod 10 for the threaded sleeve 11 to drive the U-shaped frame 9 to move up and down and reciprocate, and the inner wall of the threaded sleeve 11 is penetrated by the threaded rod 10 and screwed.

[0030] When in use, through the support groove 201 opened on the fixed frame 2 and the U-shaped frame 9 provided on the support groove 201, the support groove 201 can support the moving direction of the U-shaped frame 9, so that the U-shaped frame 9 can be lifted and moved and connected to the inner wall of the support groove 201, and the threaded rod 10 provided on the fixed frame 2, and the threaded rod 10 is driven to rotate by the motor after being energized, so that the motor can drive the threaded rod 10 to perform fixed-axis reciprocating rotation on the fixed frame 2, and the threaded sleeve 11 provided on the U-shaped frame 9, the threaded sleeve 11 is fixedly supported on the U-shaped frame 9, and the threaded sleeve 11 is sleeved on the outer contour of the threaded rod 10 and screwed, and as the threaded rod 10 performs fixed-axis reciprocating rotation, the threaded sleeve 11 can drive the rectangular plate 12 to lift and reciprocate through the U-shaped frame 9 under the action of the threaded rod 10.

[0031] The rectangular plate 12 is fixedly supported on the U-shaped frame 9 through the rectangular plate 12 provided on the U-shaped frame 9. The positioning groove 121 and the inclined groove 122 are provided on the rectangular plate 12, and the movable block 13 provided on the movable rod 4 is lifted and reciprocated along with the rectangular plate 12. Therefore, the positioning groove 121 can position and support the movable rod 4 at the center position under the action of the movable block 13, and at the same time, the inclined groove 122 can pull the movable rods 4 on both sides to move back and forth toward or away from each other through the movable block 13.

[0032] In severe windy weather, the shaking of cables causes fluctuations in current and voltage, which affects the quality of power transmission and poses a threat to the safe operation of the power grid. Figure 1 、 Figure 6 and Figure 7As shown, in the initial state, the position of the U-shaped frame 9 is at the extreme position of the top of the support groove 201. When the detection device body 7 detects that the cable current is abnormal, and the above-mentioned motor is electrically connected to the detection device body 7, the external controller can start the motor through the detection device body 7 and drive the U-shaped frame 9 to rotate. At this time, the threaded sleeve 11 drives the rectangular plate 12 to move synchronously in the downward vertical direction through the U-shaped frame 9, and the moving rod 4 at the center position is in a stationary state under the action of the positioning groove 121. At the same time, the moving rods 4 on both sides can drive the cables to move back to back under the action of the inclined groove 122, thereby increasing the spacing between the cables and avoiding multiple cables from shaking and colliding in windy weather, resulting in unstable cable current or short circuit. This further improves the accuracy and safety of current detection and reduces the current and voltage fluctuation problems caused by poor cable contact or short circuit.

[0033] When the rectangular plate 12 is reset and moved in an upward vertical direction, the above structure can be reset and moved in an opposite direction synchronously.

[0034] Example 3:

[0035] On the basis of the second embodiment, further steps are as follows: Each of the fixed plates 5 is provided with a movable groove 501 , and the inner wall of each movable groove 501 is movably connected to an inverted T-shaped block 14 that moves horizontally back and forth, and a connecting block 15 is fixedly connected to the opposite surfaces of each two adjacent inverted T-shaped blocks 14 at both ends.

[0036] Each of the connecting blocks 15 is coaxially connected to an adjusting rod 17 that pulls the inverted T-shaped block 14 to move horizontally back and forth. A fixing seat 16 is fixedly connected to the opposite surfaces on both sides of each adjacent two fixed plates 5. The end of each adjacent two adjusting rods 17 away from the connecting block 15 is respectively connected to the fixed seat 16 on the adjacent side for fixed axis rotation.

[0037] When in use, through the movable groove 501 opened on the fixed plate 5 and the inverted T-shaped block 14 provided on the movable groove 501, the movable groove 501 can support the moving direction of the inverted T-shaped block 14, so that the inverted T-shaped block 14 can be moved and connected in the horizontal direction on the inner wall of the movable groove 501, and the connecting block 15 provided on the inverted T-shaped block 14 is fixedly supported on both ends of the connecting block 15 on the inverted T-shaped blocks 14 at the adjacent two ends. The adjusting rod 17 provided on the connecting block 15 can make the two adjusting rods 17 coaxially rotatable and connected on the connecting block 15, and the fixing seat 16 provided on the fixed plate 5 can be fixedly supported on the two adjacent ends respectively. At a symmetrical position on one side of the fixed plate 5, the two adjusting rods 17 are respectively supported on the fixed seat 16 on the adjacent side for fixed axis rotation at one end away from the connecting block 15, and the inverted T-shaped blocks 14 on both sides move in opposite directions. As a result, the adjusting rods 17 can pull the inverted T-shaped blocks 14 through the connecting block 15 under the action of the fixing seat 16 to move horizontally toward the moving rod 4. When the inverted T-shaped blocks 14 on both sides are reset in opposite directions, the adjusting rods 17 can push the inverted T-shaped blocks 14 to reset and move horizontally in the direction away from the inverted T-shaped blocks 14, thereby realizing the horizontal reciprocating movement of the inverted T-shaped blocks 14 on the inner wall of the moving groove 501.

[0038] Example 4:

[0039] On the basis of the third embodiment, further steps are as follows: The retractable mechanism includes guide grooves 502 symmetrically provided on both sides of each fixed plate 5. The inner walls of the guide grooves 502 on both sides near one end of the inverted T-shaped block 14 are penetrated and movably connected to movable rods 18. The ends of the movable rods 18 on both sides are fixedly connected to clamping blocks 19 for clamping and fixing the cables.

[0040] Each of the inverted T-shaped blocks 14 is provided with a limiting groove 141 at a symmetrical position close to the movable rods 18 on both sides. The bottom ends of the movable rods 18 on both sides respectively penetrate the inner wall of the limiting groove 141 on the adjacent side and are horizontally movable and connected.

[0041] During use, through the movable groove 501 opened on the fixed plate 5 and the movable rod 18 set on the guide groove 502, the guide groove 502 can guide and support the moving direction of the movable rod 18, and through the clamping block 19 set on the movable rod 18, the clamping block 19 is fixedly supported on the movable rod 18 to ensure the stability of the clamping block 19. At the same time, the clamping block 19 can be located on both sides of the cable, and through the limiting groove 141 opened on the inverted T-shaped block 14, the limiting groove 141 can support the horizontal moving direction of the movable rod 18.

[0042] like Figure 2 、 Figure 5 and Figures 8-10As shown, as the adjusting rod 17 pulls the inverted T-shaped block 14 to move horizontally in the direction close to the movable rod 4, the inverted T-shaped block 14 can pull the movable rod 18 and the clamping block 19 to move synchronously through the limit groove 141, and the movable rod 18 can move toward each other along the inner wall of the limit groove 141 under the action of the movable groove 501, so that the movable rod 18 can drive the clamping block 19 to move toward each other and clamp it on the cable, and as the inverted T-shaped block 14 moves horizontally in the direction close to the inverted T-shaped block 14, the clamping block 19 can pull the cable to tighten it, thereby avoiding the unstable voltage and current caused by the shaking of the cable in windy weather, and further improving the accuracy of power detection.

[0043] Embodiment 5:

[0044] On the basis of the fourth embodiment, further steps are as follows: Each of the fixed plates 5 is fixedly connected to a support frame 20 at one end close to the moving rod 4, and each of the opposite surfaces at both ends of the support frame 20 is penetrated and connected to a winding roller 21 for winding and releasing the cable in a fixed axis rotation, and each of the opposite ends of the winding roller 21 and the opposite surface of the support frame 20 are fixedly connected to a torsion spring 22 for guiding the winding roller 21 to reset and rotate.

[0045] When in use, the support frame 20 is fixedly supported on the fixed plate 5 by the support frame 20 set on the fixed plate 5, and the winding roller 21 set on the support frame 20 enables the winding roller 21 to be connected to the support frame 20 on a fixed axis, and the torsion spring 22 set on the winding roller 21 enables the torsion spring 22 to support the winding roller 21, so as to guide the winding roller 21 to reset and rotate subsequently.

[0046] like Figure 2 、 Figure 8 and Figure 9 As shown, in the initial state, the torsion spring 22 is in a semi-reeled state under the action of the gravity of the cable. As the cable shakes in windy weather, the torsion spring 22 can drive the winding roller 21 to rotate back and forth on a fixed axis, and then the winding roller 21 can buffer the force of the cable shaking under the elastic force of the torsion spring 22, thereby reducing the shaking amplitude of the cable. At the same time, as the clamping block 19 pulls the cable toward the direction close to the moving rod 4, it is tightened, so that the winding roller 21 can roll and store the excess cable near one end of the moving rod 4 under the action of the torsion spring 22 released, and reset and move the cable in the direction away from the moving rod 4 as the clamping block 19 pulls. At this time, the winding roller 21 rotates under the pull of the cable and drives the torsion spring 22 to reset to the semi-reeled state. The coordinated use of the above structure not only reduces the shaking amplitude of the cable, but also protects the cable from excessive stretching or wear, thereby extending the service life of the cable.

[0047] Furthermore, the existing device can automatically tighten the cable when the current and voltage are unstable, which is easy to use and better than traditional products.

[0048] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
