The two sides of the limiting blocks do not fit with the elastic rotating part. The surface of the elastic rotating part is elastic, which increases the adjustment force.

[0013] The operation method of the device:

[0014] Step 1: Installation. After the user installs the device at the desired location, the user places the wire between the first adjustment block and the second adjustment block, and then clamps the wire through the screws, the first adjustment block and the second adjustment block. The convex teeth inside the first adjustment block and the second adjustment block can strengthen the tightness between the wire and the first adjustment block and the second adjustment block. Then the user places the first adjustment block and the second adjustment block inside the compensation body so that the tooth groove at the bottom of the first adjustment block meshes with the gear. Finally, the user closes and tightens the upper cover with screws. At this time, the device can be installed;

[0015] Step 2: automatic adjustment. When the wire encounters external pulling force, the wire will pull the first adjusting block and the second adjusting block to slide inside the compensation body. At this time, the tooth groove at the bottom of the first adjusting block can drive the gear and the elastic rotating part to rotate. When the pulling force exceeds the maximum limit of the third spring and the elastic rotating part, the surface of the elastic rotating part is deformed. At the same time, the elastic rotating part can make the push rod move toward the inside of the second limiting groove, and compress the third spring at the same time. At this time, the elastic rotating part, the push rod and the third spring cannot prevent the movement of the first adjusting block, the second adjusting block and the wire, thereby realizing automatic adjustment of the wire;

[0016] Step 3: Sliding adjustment. When the device encounters a collapse accident, the wires will be tightened. The first adjusting block and the second adjusting block can be used to adjust the wires for the first time to increase the length of the wires in the collapsed part. When the initial adjustment cannot meet the demand, the wires in the collapsed part will generate a downward tilting pulling force. The wires, the first adjusting block and the second adjusting block will cause the compensation body to generate a downward and horizontal pulling force. At this time, the downward pulling force generated by the wires will cause the lower pressure plate to move downward. At this time, the first spring is compressed by the lower pressure rod, and the square rod causes the slide bar to slide inside the inclined slide groove. At this time, the first fixed rod can be moved toward the inside of the receiving groove through the inclined slide groove and the slide rod, and the second spring is compressed at the same time. When one end of the first fixed rod is no longer inside the guide side plate, the compensation body is moved horizontally under the action of the horizontal pulling force of the wire. The slide plate and the guide side plate can ensure the stability of the movement of the compensation body, and the moving compensation body is until it fits with the side limit plates at both ends of the cross frame.

[0017] Step 4: Automatically fall off. The pressure sensor on one side of the side limit plate can detect the pulling force of the compensation body on the side limit plate, thereby detecting that the wire is subjected to pulling force. If the demand cannot be met at this time, the pressure sensor detects that the pulling force applied to the pressure sensor exceeds the set range. At this time, the electric push rod works, and the driving rod and the rotating fastener can be rotated through the working electric push rod. When the rotating fastener rotates to coincide with the through hole, the side limit plate is rotated under the extrusion pressure of the compensation body, and the top of the side limit plate rotates downward. At this time, the side limit plate no longer limits the compensation body, thereby allowing the compensation body to move out of the cross frame, thereby maximizing the length of the wire.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the user uses the device, after the user installs the device at the desired position, the user places the wire between the first adjusting block and the second adjusting block, and then clamps the wire through the screws, the first adjusting block and the second adjusting block. The convex teeth inside the first adjusting block and the second adjusting block can strengthen the tightness between the wire and the first adjusting block and the second adjusting block. Then the user places the first adjusting block and the second adjusting block inside the compensation body so that the tooth groove at the bottom end of the first adjusting block meshes with the gear. Finally, the user closes and tightens the upper cover with screws. At this time, the device can be installed. The stability between the cross frame and the installation fixing rod can be improved by the first support rod and the second support rod. When the device is in use, when the wire encounters external tension, the wire will pull the first The adjusting block and the second adjusting block slide inside the compensation body, at this time, the tooth groove at the bottom end of the first adjusting block can drive the gear and the elastic rotating part to rotate, when the pulling force exceeds the maximum limit of the third spring and the elastic rotating part, the surface of the elastic rotating part is deformed, and at the same time, the elastic rotating part can make the push rod move toward the inside of the second limiting groove, and at the same time compress the third spring, at this time, the elastic rotating part, the push rod and the third spring cannot prevent the movement of the first adjusting block, the second adjusting block and the wire, thereby realizing automatic adjustment of the wire, and then realizing protection of the wire, avoiding the wire from being torn off due to external force, when the device encounters a collapse accident, the wire will be tightened, and the wire can be initially adjusted by the first adjusting block and the second adjusting block, increasing the part where the collapse accident occurs The length of the wire, when the initial adjustment cannot meet the demand, the wire of the collapsed part will generate a downward pulling force, and the compensation body will generate a downward and horizontal pulling force through the wire, the first adjusting block and the second adjusting block. At this time, the downward pulling force generated by the wire will cause the lower pressure plate to move downward. At this time, the first spring is compressed by the lower pressure rod, and at the same time, the square rod causes the slide bar to slide inside the inclined slide groove. At this time, the first fixed rod can be moved toward the inside of the receiving groove through the inclined slide groove and the slide rod, and at the same time, the second spring is compressed. When one end of the first fixed rod is no longer inside the guide side plate, the compensation body is moved horizontally under the action of the horizontal pulling force of the wire, and the movement of the compensation body can be guaranteed by the slide plate and the guide side plate. Stability, the moving compensation body is until it fits with the side limit plates at both ends of the cross frame. The pressure sensor on one side of the side limit plate can detect the pulling force of the compensation body on the side limit plate, thereby detecting that the wire is subjected to pulling force. If the demand cannot be met at this time, the pressure sensor detects that the pulling force on the pressure sensor exceeds the set range. At this time, the electric push rod works, and the driving rod and the rotating fastener can be rotated by the working electric push rod. When the rotating fastener rotates to coincide with the through hole, the side limit plate is rotated under the extrusion force of the compensation body, and the top of the side limit plate rotates downward. At this time, the side limit plate no longer limits the compensation body, so that the compensation body moves out of the cross frame, thereby maximizing the length of the wire. This device can avoid collapse accidents.Chain collapse accidents may occur due to insufficient length of wires. At the same time, this device can protect the lines to the greatest extent, thereby preventing the wires from being damaged by external forces during the repair process, thereby reducing the repair work of users, ensuring the normal progress of the line repair work, shortening the power supply time of the line, and further reducing losses.

The top of the compensation body 11 is connected to two groups of upper cover plates 23 through a rotating shaft, and the upper cover plates 23 are connected by screws at their tops. The tops of the first adjustment block 21 and the second adjustment block 22 are connected by screws. The first adjustment block 21 and the second adjustment block 22 are respectively slidably connected to the compensation body 11, and four groups of square grooves 2 are evenly opened at the top of the cross frame 1. 4, and the square grooves 24 are respectively located between the guide side plates 12, the inside of the square grooves 24 are all slidably connected with square rods 25, and the tops of the square rods 25 are all fixedly connected to the lower pressure plate 5, and the two sides of the cross frame 1 are evenly provided with receiving grooves 26, and the receiving grooves 26 are respectively located on both sides of the square rods 25, and the middle parts of the receiving grooves 26 are all connected to the square grooves 24, and the insides of the receiving grooves 26 are all slidably connected with first fixed rods 27, and the ends of the first fixed rods 27 that are away from each other are respectively located inside the guide side plates 12, and one end of the first fixed rods 27 is fixedly connected with a second spring 28, and one end of the second spring 28 is fixedly connected to the inner wall of the receiving groove 26, and the first fixed rods 27 are provided with oblique grooves 29 on the side close to the square rods 25, and the bottom ends of the square rods 25 are symmetrically fixed. A sliding rod 30 is connected, and the sliding rod 30 is slidingly connected with the inclined slide groove 29. When the device encounters a collapse accident, the wires will be tightened, and the first adjusting block 21 and the second adjusting block 22 can be used to perform an initial adjustment on the wires to increase the length of the wires in the collapsed part. When the initial adjustment cannot meet the demand, the wires in the collapsed part will generate a downward pulling force, and the compensation body 11 will generate a downward and horizontal pulling force through the wires, the first adjusting block 21 and the second adjusting block 22. At this time, the downward pulling force generated by the wires will make The lower pressure plate 5 moves downward, and the lower pressure plate 5 makes the square rod 25, the lower pressure rod 7 and the limit rod 10 move downward. At this time, the first spring 8 is compressed by the lower pressure rod 7, and the downwardly moved square rod 25 makes the slide rod 30 slide inside the inclined slide groove 29, and the first fixed rod 27 moves to the inside of the receiving groove 26 through the inclined inclined slide groove 29, and the second spring 28 is compressed at the same time.

[0034] See also Figure 2 , Figure 5 , Figure 8 and Fig. 9 In this embodiment, the adjustment mechanism includes a convex tooth 31, a rotation groove 32, a limiting groove 33, a tooth groove 34, a gear 35, an elastic rotating member 36, a limiting block 37, a second limiting groove 38, a push rod 39 and a third spring 40. The bottom of the compensation body 11 is evenly provided with a rotation groove 32, and both sides of the compensation body 11 are evenly provided with limiting grooves 33. The bottom end of the first adjustment block 21 is provided with a tooth groove 34, and the interior of the rotation groove 32 is provided with a gear 35, and both ends of the gear 35 extend to the limiting groove 38. The interior of the groove 33 is connected to the inner wall of the limiting groove 33 through a bearing, and an elastic rotating member 36 is provided inside the limiting groove 33, and the elastic rotating member 36 is fixedly connected to both ends of the gear 35, and a limiting block 37 is fixedly connected to the gap of the elastic rotating member 36, and the inner wall of the limiting groove 33 is symmetrically provided with a second limiting groove 38, and the interior of the second limiting groove 38 is slidably connected with a push rod 39, and one end of the push rod 39 is fixedly connected to a third spring 40, and one end of the third spring 40 is fixed to the first The inner walls of the two limiting grooves 38 are fixedly connected. When the wire encounters external pulling force, the wire will pull the first adjusting block 21 and the second adjusting block 22 to slide inside the compensation body 11. At this time, the tooth groove 34 at the bottom end of the first adjusting block 21 can drive the gear 35 and the elastic rotating member 36 to rotate. When the pulling force exceeds the maximum limit of the third spring 40 and the elastic rotating member 36, the surface of the elastic rotating member 36 is deformed. Under the action of the elastic resilience of the elastic rotating member 36 itself, part of the pulling force can be offset, thereby increasing the adjusted pulling force. At the same time, the elastic rotating member 36 and the arc surface of the push rod 39 are in conflict, so that the push rod 39 can move toward the inside of the second limiting groove 38 and compress the third spring 40. At this time, the elastic rotating member 36, the push rod 39 and the third spring 40 cannot prevent the movement of the first adjusting block 21, the second adjusting block 22 and the wire, thereby realizing automatic adjustment of the wire, thereby realizing protection of the wire, preventing the wire from being torn off due to external force, and facilitating automatic adjustment of the wire.

[0035] It should be noted that a battery is provided on the inner wall at the top of the power slot 16, and the control ends of the electric push rod 18 are electrically connected to the battery through the pressure sensor 15, so as to facilitate automatic shedding. The first support rod 3 is X-shaped, which improves the stability of the connection between the cross frame 1 and the mounting fixing rod 2. The other ends of the rotating fasteners 20 are respectively the same shape as the through holes 19, and the through holes 19 and the rotating fasteners 20 are staggered, so as to facilitate the fixing of the side limit plate 14. The angle between the inclined slide 29 and the first fixing rod 27 is forty-five degrees, and the inclined grooves 29 on both sides of the square rod 25 are forty-five degrees. The slide grooves 29 are all perpendicular to each other, so that the first fixing rod 27 can be retracted through the square rod 25. The inner walls of the first adjustment block 21 and the second adjustment block 22 are evenly fixedly connected with convex teeth 31, which increases the friction between the first adjustment block 21 and the second adjustment block 22 and the wires, and is convenient for fixing the wires. One end of the push rod 39 is arc-shaped, which makes it convenient for the push rod 39 to move. The limiting blocks 37 are all fan-shaped, and the two sides of the limiting blocks 37 do not fit with the elastic rotating member 36. The surface of the elastic rotating member 36 is elastic, which increases the adjustment force.

[0036] The device operates as follows:

[0037] Step 1: Installation. After the user installs the device at the desired position, the user places the wire between the first adjustment block 21 and the second adjustment block 22, and then clamps the wire through the screws, the first adjustment block 21 and the second adjustment block 22. The convex teeth 31 inside the first adjustment block 21 and the second adjustment block 22 can strengthen the tightness between the wire and the first adjustment block 21 and the second adjustment block 22. Then the user places the first adjustment block 21 and the second adjustment block 22 inside the compensation body 11, so that the tooth groove 34 at the bottom end of the first adjustment block 21 is engaged with the gear 35. Finally, the user closes and tightens the upper cover plate 23 with screws. At this time, the device can be installed;

[0038] Step 2: Automatic adjustment. When the wire encounters external pulling force, the wire will pull the first adjusting block 21 and the second adjusting block 22 to slide inside the compensation body 11. At this time, the tooth groove 34 at the bottom of the first adjusting block 21 can drive the gear 35 and the elastic rotating member 36 to rotate. When the pulling force exceeds the maximum limit of the third spring 40 and the elastic rotating member 36, the surface of the elastic rotating member 36 is deformed. At the same time, the elastic rotating member 36 can make the push rod 39 move to the inside of the second limiting groove 38, and compress the third spring 40. At this time, the elastic rotating member 36, the push rod 39 and the third spring 40 cannot prevent the movement of the first adjusting block 21, the second adjusting block 22 and the wire, thereby realizing automatic adjustment of the wire;

[0039] Step 3: Sliding adjustment. When the device encounters a collapse accident, the wires will be tightened. The first adjustment block 21 and the second adjustment block 22 can be used to perform initial adjustment on the wires to increase the length of the wires in the collapsed part. When the initial adjustment cannot meet the demand, the wires in the collapsed part will generate a downward pulling force. The compensation body 11 generates a downward and horizontal pulling force through the wires, the first adjustment block 21 and the second adjustment block 22. At this time, the downward pulling force generated by the wires will cause the lower pressure plate 5 to move downward. At this time, the first spring 8 is compressed by the lower pressure rod 7. At the same time, the square rod 25 makes the slide bar 30 slide inside the inclined slide groove 29. At this time, the first fixed rod 27 can be moved to the inside of the receiving groove 26 through the inclined slide groove 29 and the slide bar 30, and the second spring 28 is compressed. When one end of the first fixed rod 27 is no longer inside the guide side plate 12, the compensation body 11 moves horizontally under the action of the horizontal tension of the wire. The stability of the movement of the compensation body 11 can be ensured by the slide plate 13 and the guide side plate 12, and the moving compensation body 11 is until it fits with the side limit plates 14 at both ends of the cross frame 1.

[0040] Step 4: Automatically fall off. The pressure sensor 15 on one side of the side limit plate 14 can detect the pulling force of the compensation body 11 on the side limit plate 14, thereby detecting that the wire is subjected to pulling force. If the demand cannot be met at this time, the pressure sensor 15 detects that the pulling force applied to the pressure sensor 15 exceeds the set range. At this time, the electric push rod 18 works, and the working electric push rod 18 can make the transmission rod 17 and the rotating fastener 20 rotate. When the rotating fastener 20 rotates to coincide with the through hole 19, the side limit plate 14 is rotated under the extrusion pressure of the compensation body 11, and the top of the side limit plate 14 rotates downward. At this time, the side limit plate 14 no longer limits the compensation body 11, so that the compensation body 11 moves out of the cross frame 1, thereby maximizing the length of the wire.

[0041] Working principle: When the user uses the device, after the user installs the device at the desired position, the user places the wire between the first adjustment block 21 and the second adjustment block 22, and then clamps the wire through the screws, the first adjustment block 21 and the second adjustment block 22. The convex teeth 31 inside the first adjustment block 21 and the second adjustment block 22 can strengthen the tightness between the wire and the first adjustment block 21 and the second adjustment block 22. Then the user places the first adjustment block 21 and the second adjustment block 22 inside the compensation body 11, so that the tooth groove 34 at the bottom end of the first adjustment block 21 is engaged with the gear 35. Finally, the user closes and tightens the upper cover 23 with screws. At this time, the device can be installed. Through the first support rod 3 and the second support rod 4 The stability between the cross frame 1 and the mounting fixing rod 2 can be improved. When the device is in use, when the wire encounters external pulling force, the wire will pull the first adjusting block 21 and the second adjusting block 22 to slide inside the compensation body 11. At this time, the tooth groove 34 at the bottom end of the first adjusting block 21 can drive the gear 35 and the elastic rotating member 36 to rotate. When the pulling force exceeds the maximum limit of the third spring 40 and the elastic rotating member 36, the surface of the elastic rotating member 36 is deformed. Under the action of the elastic rebound force of the elastic rotating member 36 itself, part of the pulling force can be offset, thereby increasing the adjusted pulling force. At the same time, the elastic rotating member 36 conflicts with the arc surface of the push rod 39, so that the push rod 39 can move toward the inside of the second limiting groove 38, and at the same time, the third spring 4 0 is compressed, at this time, the elastic rotating member 36, the support rod 39 and the third spring 40 cannot prevent the movement of the first adjusting block 21, the second adjusting block 22 and the wire, so as to realize the automatic adjustment of the wire, and then realize the protection of the wire, and prevent the wire from being broken due to external force. When the device encounters a collapse accident, the wire will be tightened, and the first adjusting block 21 and the second adjusting block 22 can be used to perform the initial adjustment of the wire to increase the length of the wire where the collapse accident occurs. When the initial adjustment cannot meet the demand, the wire in the collapsed part will generate a downward tilting pulling force, and the compensation body 11 will generate a downward and horizontal pulling force through the wire, the first adjusting block 21 and the second adjusting block 22. At this time, the downward pulling force generated by the wire will make The lower pressure plate 5 moves downward, and the lower pressure plate 5 makes the square rod 25, the lower pressure rod 7 and the limit rod 10 move downward. At this time, the first spring 8 is compressed by the lower pressure rod 7, and the downwardly moved square rod 25 makes the slide rod 30 slide inside the inclined slide groove 29, and the first fixed rod 27 moves to the inside of the receiving groove 26 through the inclined inclined slide groove 29, and the second spring 28 is compressed at the same time. When one end of the first fixed rod 27 is no longer in the guide side plate 12, the compensation body 11 moves horizontally under the action of the horizontal tension of the wire. The stability of the movement of the compensation body 11 can be ensured by the slide plate 13 and the guide side plate 12, and the moving compensation body 11 is until it fits with the side limit plates 14 at both ends of the cross frame 1.The pressure sensor 15 on one side of the side limit plate 14 can detect the pulling force of the compensation body 11 on the side limit plate 14, thereby detecting the pulling force on the wire. If the demand cannot be met at this time, the pressure sensor 15 detects that the pulling force on the pressure sensor 15 exceeds the set range. At this time, the electric push rod 18 works, and the working electric push rod 18 can make the transmission rod 17 and the rotating fastener 20 rotate. When the rotating fastener 20 rotates to coincide with the through hole 19, the side limit plate 14 rotates under the extrusion force of the compensation body 11, and the side limit plate The top of 14 rotates downward, and the side limit plate 14 no longer limits the compensation body 11, so that the compensation body 11 moves out of the horizontal frame 1, thereby maximizing the length of the wire. This device can avoid chain collapse accidents caused by insufficient wire length during collapse accidents. At the same time, this device can protect the line to the greatest extent, thereby avoiding damage to the wire due to external force during the repair process, thereby reducing the user's repair work, ensuring the normal progress of the line repair work, shortening the line power supply time, and further reducing losses.

After the user installs the device at the desired position, the user places the electric wire between the first adjustment block (21) and the second adjustment block (22), and then clamps the electric wire by screws, the first adjustment block (21) and the second adjustment block (22). The convex teeth (31) inside the first adjustment block (21) and the second adjustment block (22) can strengthen the tightness between the electric wire and the first adjustment block (21) and the second adjustment block (22). Then, the user places the first adjustment block (21) and the second adjustment block (22) inside the compensation body (11), so that the tooth groove (34) at the bottom end of the first adjustment block (21) is meshed with the gear (35). Finally, the user closes and tightens the upper cover plate (23) by screws. At this time, the installation of the device is completed. Step 2: automatic adjustment. When the electric wire encounters external pulling force, the electric wire will pull the first adjusting block (21) and the second adjusting block (22) to slide inside the compensation body (11). At this time, the tooth groove (34) at the bottom end of the first adjusting block (21) can drive the gear (35) and the elastic rotating member (36) to rotate. When the pulling force exceeds the maximum limit of the third spring (40) and the elastic rotating member (36), the surface of the elastic rotating member (36) is deformed. At the same time, the elastic rotating member (36) can make the push rod (39) move toward the inside of the second limiting groove (38) and compress the third spring (40). At this time, the elastic rotating member (36), the push rod (39) and the third spring (40) cannot prevent the movement of the first adjusting block (21), the second adjusting block (22) and the electric wire, thereby realizing automatic adjustment of the electric wire. Step 3: Sliding adjustment. When the device encounters a collapse accident, the wire will be tightened. The first adjustment block (21) and the second adjustment block (22) can be used to perform an initial adjustment on the wire to increase the length of the wire where the collapse accident occurs. When the initial adjustment cannot meet the demand, the wire where the collapse accident occurs will generate a downward pulling force. The wire, the first adjustment block (21) and the second adjustment block (22) cause the compensation body (11) to generate a downward and horizontal pulling force. At this time, the downward pulling force generated by the wire will cause the lower pressure plate (5) to move downward. At this time, the first spring (8) is compressed by the lower pressure rod (7), and the square rod (25) is used to The slide bar (30) slides inside the inclined slide groove (29), and the first fixed rod (27) can be moved toward the inside of the receiving groove (26) through the inclined slide groove (29) and the slide bar (30), and the second spring (28) is compressed at the same time. When one end of the first fixed rod (27) is no longer inside the guide side plate (12), the compensation body (11) moves horizontally under the action of the horizontal tension of the wire, and the stability of the movement of the compensation body (11) can be ensured by the slide plate (13) and the guide side plate (12), and the moving compensation body (11) is until it fits with the side limit plates (14) at both ends of the cross frame (1); Step 4: Automatically fall off. The pressure sensor (15) on one side of the side limit plate (14) can detect the pulling force of the compensation body (11) on the side limit plate (14), thereby detecting that the wire is subjected to pulling force. If the demand cannot be met at this time, when the pressure sensor (15) detects that the pulling force on the pressure sensor (15) exceeds the set range, the electric push rod (18) works. The working electric push rod (18) can make the transmission rod (17) and the rotating fastener (20) rotate. When the rotating fastener (20) rotates to coincide with the through hole (19), the side limit plate (14) rotates under the extrusion force of the compensation body (11). The top of the side limit plate (14) rotates downward. At this time, the side limit plate (14) no longer limits the compensation body (11), so that the compensation body (11) moves out of the cross frame (1), thereby maximizing the length of the wire.
