[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figure 1-Figure 11 As shown, a distribution line temperature measuring clamp according to an embodiment of the present invention comprises a shell 1, a detection mechanism 2 and a fixing mechanism 3, wherein the detection mechanism 2 is installed inside the shell 1, the detection mechanism 2 comprises a sensor 21 and a power taking component 22, the sensor 21 is used to measure the temperature of the distribution line, the power taking component 22 is used to supply power to the sensor 21, and the fixing mechanism 3 comprises: a No. 1 clamping component 31, the No. 1 clamping component 31 comprises: a connecting block 3101 installed in the shell 1, the middle part of the connecting block 3101 is provided with a circular hole for the distribution line to pass through; a No. 1 pressing plate 3102 slidably installed on the connecting block 3101; a driving mechanism 3102 to drive the No. 1 clamping component 31. A screw 3103 slides on the No. 1 pressure plate 3102, the screw 3103 is threadedly connected to the connecting block 3101, and the screw 3103 is rotatably connected to the No. 1 pressure plate 3102; a No. 1 rotating component 32 for driving the screw 3103 to rotate, the No. 1 rotating component 32 includes: a special-shaped groove 321 opened on the screw 3103; a round block 322 rotatably installed on the screw 3103, a part of the round block 322 is inserted into the special-shaped groove 321, a trapezoidal block 323 is slidably installed on the part of the round block 322 inserted into the special-shaped groove 321, and a No. 1 spring 324 is installed between the trapezoidal block 323 and the round block 322.

[0035] Specifically, the fixing mechanism 3 of the existing temperature measuring wire clamp generally includes a threaded rod and a pressure plate. Rotating the threaded rod can drive the pressure plate to move so that the pressure plate presses the distribution line tightly. This clamping method has the problem of excessive downward pressure of the pressure plate, which causes damage to the distribution line. In this temperature measuring wire clamp, the sensor 21 adopts the existing temperature sensor, which is provided with a wireless transmission mechanism module, and the detected temperature can be fed back to the database of the computer system through the wireless transmission module. The power-taking component 22 adopts the existing air-to-air power-taking device that converts the magnetic field generated by the wire into an induced current. During installation, the distribution line is passed through the circular hole of the connecting block 3101 and the power-taking component 22, and the circular block 322 is rotated. The circular block 322 drives the trapezoidal block 323 to rotate synchronously. The rotation of the trapezoidal block 323 drives the screw 3103 to rotate. The rotation of the screw 3103 causes the No. 1 pressure plate 3102 to move downward until the No. 1 pressure plate 3102 The distribution line is compressed. After the No. 1 pressure plate 3102 compresses the distribution line, the movement of the No. 1 pressure plate 3102 is blocked, so the screw 3103 is difficult to rotate. If the round block 322 continues to rotate, the trapezoidal block 323 moves toward the inside of the round block 322, and the screw 3103 can no longer be driven to rotate. At this time, the action of clamping the distribution line is realized, and the sensor 21 is attached to the distribution line. In daily use, power is supplied to the sensor 21 through the power taking component 22. The sensor 21 measures the temperature of the distribution line in real time and feeds back the temperature of the distribution line to the computer's database, so that the staff can monitor the temperature of the distribution line; by setting the No. 1 rotating component 32, after the No. 1 pressure plate 3102 compresses the distribution line, the No. 1 rotating component 32 rotates, and the No. 1 pressure plate 3102 no longer moves, thereby avoiding the problem of excessive compression of the No. 1 pressure plate 3102 and damage to the distribution line.

[0036] like Figure 4 and Figure 5 As shown, the connection block 3101 contains a number of No. 1 pressure plates 3102 distributed in a ring array, a circular plate 3104 is rotatably mounted on the connection block 3101, an arc groove 3105 is provided on the circular plate 3104, and the No. 1 pressure plate 3102 is slidably connected to the arc groove 3105.

[0037] Specifically, when the first pressing plate 3102 connected to the screw rod 3103 moves downward, the first pressing plate 3102 slides on the arc groove 3105 of the circular plate 3104, so the circular plate 3104 rotates clockwise (by Figure 4 For example), the circular plate 3104 rotates clockwise, so that the remaining No. 1 pressure plates 3102 move toward the center of the circular hole of the connecting block 3101, until multiple No. 1 pressure plates 3102 clamp the distribution line together, thereby achieving the action of clamping the distribution line.

[0038] like Figure 4As shown, a No. 1 air cushion 3106 is detachably installed below the No. 1 pressure plate 3102, and the side of the No. 1 air cushion 3106 facing the center of the circular hole is a flat surface.

[0039] Specifically, the distribution line is generally circular, and when the No. 1 pressure plate 3102 approaches the distribution line, one point of the No. 1 air cushion 3106 first contacts the distribution line, and the No. 1 pressure plate 3102 continues to press down, and the No. 1 air cushion 3106 is squeezed, and the internal gas moves to both sides of the first contact position, so that the two sides of the No. 1 air cushion 3106 bulge, and after swelling, they can contact the surface of the distribution line; by setting the No. 1 air cushion 3106, after the No. 1 pressure plate 3102 presses the distribution line, the side of the No. 1 air cushion 3106 facing the center of the circular hole of the connecting block 3101 can fit the surface of the distribution line, so that the fixing component can adapt to distribution lines of different specifications, and the No. 1 air cushion 3106 can disperse the pressure of the No. 1 pressure plate 3102 to avoid excessive local pressure when the wire is clamped by the No. 1 pressure plate 3102.

[0040] like Figure 2 , Figure 3 , Fig. 9 and Fig.11 As shown, the fixing mechanism 3 also includes: a ratchet 33 fixedly mounted on the round block 322; a rack plate 34 slidably mounted on the housing 1, the rack plate 34 adopts an up and down telescopic structure, and a ratchet pawl 316 for driving the ratchet 33 to rotate unidirectionally is rotatably mounted on the rack plate 34.

[0041] Specifically, the rack plate 34 adopts a spring-controlled telescopic structure. The rack plate 34 is attached to the lower surface of the round block 322. When the round block 322 moves up and down following the screw rod 3103, the rack plate 34 is pushed up and down by the round block 322 and the internal spring. The pawl 316 and the ratchet 33 form a unidirectional rotating ratchet and pawl structure. The rack plate 34 moves to the left and drives the ratchet 33 to rotate through the pawl 316. The rack plate 34 moves to the right and does not drive the ratchet 33 to rotate. After the No. 1 clamping assembly 31 and the No. 2 clamping assembly 310 both fix the power distribution line, a belt 4 can be installed between the two ratchet wheels 33 of the No. 1 clamping assembly 31 and the No. 2 clamping assembly 310 to drive the two ratchet wheels 33. When one ratchet wheel 33 rotates, the other ratchet wheel 33 rotates together. Fig. 9 As shown in FIG. 1 , the belt 4 is located below the teeth of the two ratchets 33 and does not hinder the cooperation between the ratchets 33 and the pawls 316 .

[0042] like Figure 2 , Figure 3 and Fig.11As shown, the fixing mechanism 3 also includes: a No. 2 gear 35 rotatably mounted on the housing 1, the No. 2 gear 35 being meshedly connected with the rack plate 34; a No. 2 rotating component 36 mounted on the No. 2 gear 35, the No. 2 rotating component 36 being consistent with the No. 1 rotating component 32, the special-shaped groove 321 of the No. 2 rotating component 36 being opened on the No. 2 gear 35; and a windward plate 37 fixedly mounted on the round block 322 of the No. 2 rotating component 36.

[0043] Specifically, after long-term use, the screw 3103 may become loose due to factors such as wind vibration, and the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 may not firmly clamp the power distribution line; a torsion spring is provided between the pawl 316 and the rack plate 34 to reset the pawl 316 after rotation;

[0044] When strong winds occur, the wind force will drive the second rotating assembly 36 containing the windward plate 37 to rotate;

[0045] If the second rotating assembly 36 rotates clockwise ( Fig.11 Looking from top to bottom), at this time:

[0046] If the pawl 316 is located on the right side of the ratchet 33, the rack plate 34 can be pushed to slide to the left through the cooperation of the No. 2 gear 35 and the No. 2 rotating assembly 36. The rack plate 34 slides to the left and drives the pawl 316 to slide synchronously. The sliding of the pawl 316 causes the ratchet 33 to rotate. The rotation of the ratchet 33 drives the No. 1 rotating assembly 32 to rotate. If the screw 3103 is loose, the No. 1 rotating assembly 32 can drive the screw 3103 to rotate, so that the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 clamp the power distribution line again. Otherwise, the screw 3103 does not rotate together with the No. 1 rotating assembly 32.

[0047] If the pawl 316 is located on the left side of the ratchet wheel 33, the rack plate 34 cannot move to the left due to the travel limit of the rack plate 34, and the second gear 35 does not rotate with the second rotating assembly 36;

[0048] If the second rotating assembly 36 rotates counterclockwise under the influence of wind, then:

[0049] If the pawl 316 is located on the left side of the ratchet 33, the rack plate 34 and the pawl 316 can be pushed to slide to the right through the cooperation of the second gear 35 and the second rotating assembly 36. During the sliding to the right, the pawl 316 contacts the ratchet 33, the pawl 316 rotates, and the ratchet 33 does not move until the rack plate 34 and the pawl 316 return to their initial positions;

[0050] If the pawl 316 is located on the right side of the ratchet wheel 33, the rack plate 34 cannot move to the right due to the travel limit of the rack plate 34, and the second gear 35 does not rotate with the second rotating assembly 36;

[0051] By providing the second rotating assembly 36 and the rack plate 34, the ratchet wheel 33 and the first rotating assembly 32 are rotated by utilizing wind force, so that the screw 3103 can be tightened again when the screw 3103 is loose, thereby improving the above-mentioned situation.

[0052] like Figure 2 , Figure 3 and Figure 8 As shown, a No. 2 clamping assembly 310 is installed in the shell 1, and the No. 2 clamping assembly 310 has the same structure as the No. 1 clamping assembly 31, and the No. 2 clamping assembly 310 is slidably connected to the shell 1, and a number of No. 2 pressure plates 38 are distributed in a circular array between the No. 1 clamping assembly 31 and the No. 2 clamping assembly 310, and a No. 2 air cushion 39 is fixedly installed on the No. 2 pressure plate 38, and the No. 2 pressure plate 38 is slidably connected to the shell 1, and the length of the No. 2 pressure plate 38 is greater than the length of the No. 1 pressure plate 3102.

[0053] Specifically, during installation, first control the No. 2 clamping assembly 310 and the No. 1 clamping assembly 31 to perform preliminary clamping on the distribution line, then control the No. 2 clamping assembly 310 to slide to the right to straighten the distribution line, and then control the No. 2 pressure plate 38 and the No. 2 air cushion 39 to move toward the direction close to the distribution line until the No. 2 pressure plate 38 and the No. 2 air cushion 39 clamp the distribution line tightly, thus completing the clamping of the distribution line, avoiding the problem of bending of the wire and poor clamping effect during clamping.

[0054] like Figure 3 and Figure 4 As shown, the fixing mechanism 3 also includes: a No. 1 telescopic rod 311 installed between the No. 1 clamping component 31 and the No. 2 clamping component 310; a No. 3 rotating component 312 installed on the connecting block 3101, the special-shaped groove 321 of the No. 3 rotating component 312 is opened at the movable end of the No. 1 telescopic rod 311, and the No. 3 rotating component 312 is used to drive the No. 1 telescopic rod 311 to extend and retract; a No. 3 gear 313 fixedly installed on the No. 3 rotating component 312; a No. 4 gear 314 used to drive the No. 3 gear 313 to rotate, and the No. 4 gear 314 is fixedly installed on the circular plate 3104.

[0055] like Figure 8 As shown, the fixing mechanism 3 further includes: a plurality of push rods 315 installed in a circular array in the housing 1, the push rods 315 are slidably connected to the housing 1, and the push rods 315 are used to drive the second pressure plate 38 to slide.

[0056] Specifically, the No. 1 telescopic rod 311 is composed of a screw and a sleeve with a matching thread. The sleeve is fixedly installed on the connecting block 3101 of the No. 1 clamping assembly 31 and is a fixed part. The screw is a movable part and is connected to the No. 3 rotating assembly 312. When in use, the rotation of the circular plate 3104 drives the No. 4 gear 314 to rotate synchronously. The rotation of the No. 4 gear 314 causes the No. 3 gear 313 to rotate. The rotation of the No. 3 gear 313 causes the No. 3 rotating assembly 312 to rotate. The rotation of the No. 3 rotating assembly 312 causes the No. 1 telescopic rod 311 to extend, thereby pushing the No. 2 clamping assembly 310 to move to the right. During the movement, the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 clamp the power distribution line. The No. 1 pressure plate 3102 and the No. 1 air cushion 310 When the 6 pairs of distribution wires are clamped loosely, the distribution wires can be pulled straightened. When the distribution wires can no longer move, the No. 1 telescopic rod 311 will no longer extend. Therefore, even if the No. 3 rotating component 312 continues to rotate, the trapezoidal block 323 of the No. 3 rotating component 312 moves toward the inside of the circular block 322, and the rotation of the No. 3 rotating component 312 no longer drives the movable part of the No. 1 telescopic rod 311 to rotate, so as to avoid the distribution wires from being pulled and damaged. At this time, the push rod 315 can be controlled to move toward the direction close to the distribution wires, pushing the No. 2 pressure plate 38 and the No. 2 air cushion 39 to clamp the distribution wires. At the same time, the circular plate 3104 continues to rotate until the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 press the distribution wires tightly. There is no need to set up additional devices to control the movement of the No. 2 clamping component 310, which is easy to use.

[0057] like Figure 8 and Fig. 9 As shown, the fixing mechanism 3 also includes: an arc plate 317 horizontally slidably mounted on the No. 2 pressure plate 38 of the No. 2 clamping assembly 310, and the arc plate 317 is slidably connected to the shell 1; a support plate 318 fixedly mounted on the arc plate 317; a triangular block 319 horizontally slidably mounted on the arc plate 317, the inclined surface of the triangular block 319 facing upward, the triangular block 319 is located within the moving range of the No. 2 pressure plate 38, and the triangular block 319 is used to clamp the No. 2 pressure plate 38 between the triangular block 319 and the support plate 318; a No. 2 spring 320 mounted between the triangular block 319 and the arc plate 317.

[0058] Specifically, when the No. 2 pressure plate 38 and the No. 2 air cushion 39 are pushed by the push rod 315 to move toward the direction close to the power distribution line, the No. 2 pressure plate 38 will contact the inclined surface of the triangular block 319 and push the triangular block 319 to move toward the direction close to the connecting block 3101. At this time, the No. 2 spring 320 is compressed until the No. 2 pressure plate 38 contacts the abutment plate 318. At this time, the triangular block 319 moves to the upper surface of the No. 2 pressure plate 38 under the action of the elastic force of the No. 2 spring 320. Plate 38 is stuck between the abutment plate 318 and the triangular block 319, so the No. 2 pressure plate 38 is connected to the arc plate 317. When the arc plate 317 moves with the No. 1 pressure plate 3102, the No. 2 pressure plate 38 can move synchronously. Therefore, in daily use, when the rack plate 34 tightens the loose screw 3103, the No. 2 pressure plate 38 can move synchronously with the No. 1 pressure plate 3102 to ensure that the clamping force of the No. 2 pressure plate 38 and the No. 2 air cushion 39 on the distribution line remains unchanged.

[0059] like Fig.10 As shown, the first air cushion 3106 and the second air cushion 39 have multiple air chambers horizontally distributed inside, and each air chamber is not connected to each other.

[0060] Specifically, since the interior of air cushion No. 1 3106 and air cushion No. 2 39 is composed of multiple air chambers, if air cushion No. 1 3106 and air cushion No. 2 39 have gaps due to aging or other factors, only one of the air chambers will leak, and the entire air cushion No. 1 3106 or air cushion No. 2 39 will not be damaged.

[0061] Working principle: During installation, pass the distribution line through the round hole of the connecting block 3101 and the power taking component 22, rotate the round block 322 of the No. 1 clamping component 31, the round block 322 drives the trapezoidal block 323 to rotate synchronously, the rotation of the trapezoidal block 323 drives the screw 3103 to rotate, the rotation of the screw 3103 causes the No. 1 pressure plate 3102 connected thereto to move downward, and since the No. 1 pressure plate 3102 slides on the arc groove 3105 of the circular plate 3104, the circular plate 3104 rotates clockwise (with Figure 4For example), the circular plate 3104 rotates clockwise, so that the remaining No. 1 pressure plates 3102 all move toward the center of the circular hole of the connecting block 3101. The distribution line is generally circular. When the No. 1 pressure plate 3102 approaches the distribution line, one part of the No. 1 air cushion 3106 first contacts the distribution line, and the No. 1 pressure plate 3102 continues to press down, and the No. 1 air cushion 3106 is squeezed, and the internal gas moves to both sides of the first contact position, so that the two sides of the No. 1 air cushion 3106 swell, and after swelling, they can contact the surface of the distribution line, until the side of the No. 1 air cushion 3106 that contacts the distribution line contacts the distribution line, and multiple No. 1 air cushions 3106 are in contact with each other. 106 cooperates with each other to clamp the distribution line, thereby realizing the clamping action, and then the round block 322 of the No. 2 clamping assembly 310 is rotated to clamp the distribution line. During the clamping process, the rotation of the round plate 3104 drives the No. 4 gear 314 to rotate synchronously, the rotation of the No. 4 gear 314 causes the No. 3 gear 313 to rotate, the rotation of the No. 3 gear 313 causes the No. 3 rotating assembly 312 to rotate, and the rotation of the No. 3 rotating assembly 312 causes the No. 1 telescopic rod 311 to extend, thereby pushing the No. 2 clamping assembly 310 to move to the right. During the movement, the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 clamp the distribution line. When the No. 1 pressure plate 3102 and the No. 1 air cushion 3106 hold the distribution line loosely, the distribution line can be pulled straight. When the distribution line can no longer move, the No. 3 rotating assembly 312 rotates, and the No. 1 telescopic rod 311 no longer extends to prevent the distribution line from being pulled and damaged. After the No. 1 telescopic rod 311 no longer extends, the push rod 315 is first pushed to slide in the direction close to the distribution line, driving the No. 2 pressure plate 38 and the No. 2 air cushion 39 to move in the direction close to the distribution line. During the movement, the No. 2 pressure plate 38 will contact the inclined surface of the triangular block 319 and push the triangular block 319 to move in the direction close to the connecting block 3101. At this time The No. 2 spring 320 is compressed until the No. 2 pressure plate 38 contacts the abutment plate 318. At this time, the triangular block 319 moves to the upper surface of the No. 2 pressure plate 38 under the action of the elastic force of the No. 2 spring 320, and the No. 2 pressure plate 38 is stuck between the abutment plate 318 and the triangular block 319. Therefore, the No. 2 pressure plate 38 is connected to the arc plate 317, and the circular plate 3104 continues to rotate. The No. 1 pressure plate 3102 moves through the arc plate 317 to drive the No. 2 pressure plate 38 to move synchronously until the No. 1 pressure plate 3102, the No. 1 air cushion 3106, the No. 2 pressure plate 38 and the No. 2 air cushion 39 press the distribution line tightly, that is, the action of straightening first and then clamping is realized.
