Description

Technical Field

[0001] The invention relates to the technical field of temperature measurement of wire clamps, and in particular to a transmission line wire clamp with a temperature measurement function. Background Art

[0002] Transmission line clamps are devices used to fix and connect transmission lines. There are many types of transmission line clamps, among which the boat-type suspension clamp is a device used to fix transmission cables on poles and towers. Its structure includes three main parts: a hanger, a U-shaped screw and a hull. The hanger is a component for fixing the clamp, which is connected to the pole tower by expansion screws. There is a horizontal shaft in the center of the hanger, and there are two lifting ears on the shaft for lifting the cable. The U-shaped screw is a component for adjusting the cable. Its shape is similar to the letter U. The opening is used to lift the cable, and the bottom passes through the screw hole on the hanger. The hull is a component for carrying the cable. Its shape is similar to a boat, and there is a row of vertical support plates inside to support the cable. When in use, the cable needs to be arranged into a horizontal state, and then placed inside the hull, and then the U-shaped screw is passed through the cable and fixed to the hanger. Finally, by adjusting the length of the U-shaped screw, the height and horizontal state of the cable can be adjusted.

[0003] However, in hot seasons, the ambient temperature is high, and the boat-type suspension clamp is usually made of metal materials with good thermal conductivity. Therefore, in hot weather, the boat-type suspension clamp will absorb heat from the environment and transfer it to the wire in contact with it. Since the material of the wire is usually metal, it has the property of thermal expansion and contraction. When the temperature rises, the tiny molecules and atoms in the conductor will begin to vibrate, resulting in a tiny expansion. This expansion will cause the length of the wire to increase, while the cross-sectional area of ​​the wire will decrease. Moreover, metal wires are usually stretched into a slender shape, which makes it easier for them to extend to both sides when they expand and contract, rather than increasing the diameter in the cross section. At the same time, the boat-type Suspension clamps are usually made of polymer materials, which have a smaller thermal expansion coefficient than metal conductors, resulting in a reduction in the clamping force of the boat-type suspension clamp on the conductor. The conductor is easily displaced between the boat-type suspension clamp, which causes greater friction and stress on the insulation layer on the outside of the conductor, accelerating the wear and aging of the insulation layer, and reducing its insulation performance. The increase in conductor temperature will increase the resistance of the conductor and the current density, which can easily cause a short circuit in the conductor. As a result, in hot weather, workers need to strengthen the inspection and maintenance of transmission lines, monitor the temperature of the clamps, and deal with the overheated clamps in a timely manner after discovering them, which places a heavy workload on the workers. To this end, we propose a transmission line clamp with a temperature measurement function. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-12 The present invention provides a technical solution: a transmission line clamp with a temperature measurement function, comprising a clamp housing 1 and a clamp block 2, the clamp block 2 being located on the inner wall of the clamp housing 1; a support box 3, the support box 3 being fixedly connected to the top of the clamp block 2, the support box 3 being made of metal; a temperature measuring mechanism 4, the temperature measuring mechanism 4 being located on the inner wall of the support box 3, the temperature measuring mechanism 4 being able to monitor the surface temperature of the support box 3; a protection mechanism 5, the protection mechanism 5 being located on the inner wall of the clamp block 2, the protection mechanism 5 being able to perform protection processing on the wire between the clamp block 2 and the clamp housing 1 according to the temperature measured by the temperature measuring mechanism 4;

[0033] During installation, the staff first fixes the wire clamp housing 1 to the pole tower, then splices the wire clamp housing 1 and the clamp block 2 on the outside of the cable, then moves the wire clamp housing 1 to a predetermined position, tightens the bolts, and the clamp block 2 and the wire clamp housing 1 cooperate with each other to fix the cable;

[0034] When in use, since the support box 3 is exposed to the environment and is in direct contact with the surface of the clamp block 2, if in a hot season, when the ambient temperature rises, the support box 3 and the clamp block 2 will be affected by heat radiation or heat convection, etc., causing their surface temperature to rise. Since the material of the wire is usually metal, it has the property of thermal expansion and contraction. When the temperature rises, the tiny molecules and atoms in the conductor will begin to vibrate, thereby producing a tiny expansion. This expansion will cause the length of the wire to increase, while the cross-sectional area of ​​the wire will decrease. Moreover, metal wires are usually stretched into an elongated shape, which makes it easier for them to extend to both sides when they expand and contract, rather than increasing the diameter in the cross section. Therefore, when the temperature of the wire is relatively high, the clamping force of the clamp block 2 on the wire is reduced, and the temperature measuring mechanism 4 will be pre-measured when in use. Two thresholds are set first. When the support box 3 reaches the first threshold, the temperature measuring mechanism 4 will control the protection mechanism 5 to work. The protection mechanism 5 cooperates with the clamp block 2 to clamp the wire inside the clamp block 2, so as to avoid the wire shaking on the inner wall of the clamp block 2 under the action of high-altitude wind, causing the insulation layer on the surface of the wire to be worn. When the support box 3 reaches the second threshold, the second threshold is close to the overheating temperature of the clamp block 2. The temperature measuring mechanism 4 detects the second threshold, and the temperature measuring mechanism 4 will alarm to notify the background staff and control the protection mechanism 5 to work. The protection mechanism 5 can enhance the heat dissipation inside the clamp block 2 to avoid heat accumulation between the clamp block 2 and the wire, and send an alarm to the staff through the temperature measuring mechanism 4, thereby extending the reaction time for the staff and reducing the risk.

[0035] The temperature measuring mechanism 4 includes a moving box 40 slidably connected to the inner wall of the supporting box 3, and moving blocks 41 are fixedly connected on both sides of the moving box 40. The inner wall of the supporting box 3 is provided with a moving groove 42 that can be slidably connected to the moving block 41, and the inner wall of the moving groove 42 is provided with an alarm member 43. The inner wall of the moving box 40 is slidably connected with a moving plate 44, and a deformation block 1 45 is arranged between the moving plate 44 and the top of the moving box 40. A deformation block 2 413 is arranged between the moving box 40 and the top of the supporting box 3. The heat required for the deformation of the deformation block 1 45 is lower than the heat required for the deformation of the deformation block 2 413. The deformation block 1 45 and the deformation block 2 413 are paraffin. Since the melting point temperature range of paraffin is relatively large, in the present application, the preferred melting temperature range of the deformation block 1 45 is 70 -80℃, the preferred melting temperature range of the deformation block 2 413 is 80-90℃, so that the temperature of the surface of the support box 3 at this time can be reflected in real time through the state of the paraffin, so as to achieve the effect of measuring the temperature of the support box 3. For conventional temperature sensors, when working at high altitudes, they will be affected by wind vibration and rainy weather, which may easily lead to a reduction in the service life of the temperature sensor. A transmission rod 46 is fixedly connected to the bottom of the movable plate 44, and a piston plate 47 is fixedly connected to one end of the transmission rod 46 away from the movable plate 44. A connecting groove 48 is provided on the inner wall of the clamping block 2, and the piston plate 47 is slidably connected to the inner wall of the connecting groove 48. A reset spring 49 capable of pushing the piston plate 47 to reset is fixedly connected to the bottom of the piston plate 47, and one end of the reset spring 49 is fixedly connected to the inner wall of the connecting groove 48;

[0036] When the temperature of the moving box 40 reaches 70-80°C, the deformation block 45 between the moving plate 44 and the top of the moving box 40 begins to melt, and the volume of the paraffin wax expands after melting, thereby pushing the moving plate 44 to slide along the inner wall of the moving box 40, and the moving plate 44 drives the transmission rod 46 to move, and the transmission rod 46 drives the piston plate 47 to slide along the inner wall of the connecting groove 48, so that the piston plate 47 presses the airflow at the bottom of the connecting groove 48 into the protection mechanism 5 while squeezing the return spring 49, and the protection mechanism 5 automatically cooperates with the clamping block 2 to fix the wire, so as to prevent the wire from shaking on the inner wall of the clamping block 2 and improve the stability of the wire. When the temperature drops, the paraffin wax will solidify again, and the return spring 49 in the compressed state will push the piston plate 47 to slide upward along the inner wall of the connecting groove 48, and the piston plate 47 drives the transmission rod 46 to move, and the transmission rod 46 drives the moving plate 44 to move upward along the inner wall of the moving box 40, so as to cooperate with the next time when the temperature rises again, and then increase the clamping force on the wire.

[0037] When the temperature of the moving box 40 reaches 80-90°C, the deformation block 2 413 located between the moving box 40 and the top of the supporting box 3 begins to melt. Since the volume of the paraffin expands after melting, the moving box 40 is pushed to drive the moving block 41 to slide on the inner wall of the moving groove 42. The moving block 41 moves and triggers the alarm 43. The alarm 43 works to cooperate with the reminder of the staff, and the downward movement of the moving box 40 will drive the moving plate 44 to move. The moving plate 44 drives the transmission rod 46 to move. The transmission rod 46 drives the piston plate 47 to slide along the inner wall of the connecting groove 48 to cooperate with the protection mechanism 5 to work. The protection mechanism 5 increases the heat dissipation between the clamping block 2 and the wire while increasing the clamping force on the wire, avoiding heat accumulation between the clamping block 2 and the wire, and increasing the reaction time of the staff.

[0038] The alarm member 43 includes an alarm button 410 fixedly connected to the inner wall of the movable groove 42, an alarm 411 fixedly connected to the top of the clamp block 2, and solar photovoltaic components 412 capable of supplying power to the alarm 411 are respectively provided on both sides of the top of the clamp block 2. The solar photovoltaic component 412 is a mature existing technology. The solar photovoltaic component 412 refers to a device that converts sunlight into electrical energy using the photovoltaic effect, including solar cells. Solar cells are usually made of silicon materials, which have excellent semiconductor properties. A photovoltaic panel is usually composed of a plurality of solar cell units, which are connected in parallel or in series to form a solar cell panel; a junction box, which is the circuit connection part of the photovoltaic component, used to connect the solar cell and the external circuit, and the electrical energy can be derived from the photovoltaic component through the junction box; a connector, which is used to connect the solar cell panel and the electrical appliance, and other structural components. Through the solar photovoltaic component 412, the wire clamp housing 1 can also use the collected and converted solar energy to supply power to the alarm 411 when working at high altitude;

[0039] When the moving block 41 slides along the inner wall of the moving groove 42 and triggers the alarm button 410 , the alarm 411 sends an alarm to the backstage, thereby reminding the staff that the wire clamp housing 1 has an overheating risk.

[0040] The protection mechanism 5 includes a plurality of airbags 50 located on the inner wall of the clamp block 2. The surface of the airbags 50 is coated with a fireproof insulating coating. There are three airbags 50, one of which is located in the middle of the clamp block 2, and the remaining two are symmetrically distributed on both sides of the clamp block 2. During installation, the staff can assemble the clamp block 2 and the wire clamp housing 1 by using the middle airbag 50 as a reference. The inner wall of the clamp block 2 is provided with a placement groove 51 that can be fixedly connected to the airbag 50. The inner wall of the clamp block 2 is provided with an air inlet hole 52, and one end of the air inlet hole 52 is respectively connected to the plurality of airbags 50. The air inlet hole 52 is connected to the connecting groove 48 at one end away from the airbag 50, and a sliding plate 53 is slidably connected to the inner wall of the air inlet hole 52. An air inlet 54 is provided on the inner wall of the sliding plate 53. A limiting member 55 capable of limiting the sliding plate 53 is provided on the inner wall of the air inlet hole 52. An adjusting member 56 capable of adjusting the air intake amount is provided on the inner wall of the air inlet hole 52 close to the airbag 50. A ventilation hole 57 is provided on the inner wall of the clamping block 2. A closing member 58 capable of controlling the opening and closing of the ventilation hole 57 according to the surface temperature of the support box 3 is provided on the inner wall of the ventilation hole 57.

[0041] If the deformation block 45 between the moving plate 44 and the top of the moving box 40 begins to melt, the volume of the paraffin wax expands after melting, thereby pushing the moving plate 44 to slide along the inner wall of the moving box 40, and the moving plate 44 drives the transmission rod 46 to move, and the transmission rod 46 drives the piston plate 47 to slide along the inner wall of the connecting groove 48, so that the piston plate 47 presses the air flow at the bottom of the connecting groove 48 into the air inlet hole 52 while squeezing the return spring 49, and the air flow pushes the sliding plate 53 to slide in the air inlet hole 52, and the sliding plate 53 is pressed by the limiter 55. 3 is limited. After the sliding plate 53 is limited, the airflow passes through the air inlet 54 in the middle of the sliding plate 53 and enters the airbag 50 after being regulated by the adjusting member 56. The airbag 50 swells to fix the wire in the clamping block 2. Since the airbags 50 on both sides are symmetrically distributed, the wire can be kept stable and not tilted after being fixed by the airbag 50. At the same time, since the airbag 50 fixes the wire by lifting it upward, the wire can also be fixed to reduce the extension amount of the wire due to heat, so as to avoid the increase of the downward bending amplitude of the wire.

[0042] If the deformation block 2 413 between the moving box 40 and the top of the supporting box 3 also starts to melt, the volume of the paraffin expands after melting, thereby pushing the moving box 40 to drive the moving block 41 to slide on the inner wall of the moving groove 42, and the moving box 40 moves downward to drive the moving plate 44 to move, the moving plate 44 drives the transmission rod 46 to move, and the transmission rod 46 drives the piston plate 47 to slide along the inner wall of the connecting groove 48, and the piston plate 47 presses the air in the connecting groove 48 into the air inlet 52, and the airflow that enters drives the sliding The plate 53 moves to the second limit point of the limit member 55, and the sliding plate 53 moves to drive the adjusting member 56 to work. The adjusting member 56 reduces the amount of air entering the airbag 50, and the sliding plate 53 moves to drive the closing member 58 to work. The closing member 58 opens the vent 57 on the inner wall of the clamp 2, and the airflow in the air inlet 52 enters the vent 57 through the gap of the closing member 58, and blows toward the wire in the clamp 2 through the vent 57, and cooperates with the airflow in the high altitude to improve the heat dissipation of the wire inside the clamp 2;

[0043] If the temperature is lower than the melting point of paraffin, the paraffin begins to solidify, and the return spring 49 in the compressed state will push the piston plate 47 to move upward, so that the moving box 40 and the moving plate 44 can be reset to cooperate with the next temperature rise to continue working.

[0044] The limiting member 55 includes a limiting block 59 fixedly connected to both sides of the sliding plate 53, the limiting block 59 is slidably connected to the inner wall of the air inlet hole 52, and the inner wall of the air inlet hole 52 is slidably connected to two clamping blocks 510, the inner wall of the limiting block 59 is provided with a clamping groove 511 that can be clamped with the clamping block 510, and the clamping block 510 is fixedly connected to the end away from the limiting block 59. A compression spring 512 is fixedly connected to the inner wall of the clamping block 2. Since the diameter of the air inlet 54 in the middle of the sliding plate 53 is small, when the airflow enters the air inlet hole 52, the airflow will push the sliding plate 53 to slide along the inner wall of the air inlet hole 52, and the end of the limiting block 59 The arc-shaped edge of the clamping block 510 is squeezed by the part, thereby pushing the clamping block 510 to slide along the inner wall of the clamping block 2 and squeezing the compression spring 512. When the clamping block 510 moves to the corresponding position of the clamping groove 511, the compression spring 512 in the compressed state will push the clamping block 510 to slide into the inner wall of the clamping groove 511 to cooperate with the limiting block 59. When the airflow pushes the sliding plate 53 again, the arc-shaped edge of the clamping block 510 and the inner wall of the clamping groove 511 are squeezed against each other, so that the clamping block 510 will slide out of the clamping groove 511 and squeeze the compression spring 512 again, thereby releasing the limiting of the limit block 59 by the clamping block 510.

[0045] The adjusting member 56 includes an adjusting plate 513 slidably connected to the inner wall of the air inlet hole 52, an adjusting hole 514 is opened in the inner wall of the adjusting plate 513, baffles 515 are slidably connected to the inner walls of both sides of the adjusting plate 513, a spring sheet 516 is fixedly connected to the outer side of the baffle 515, one end of the spring sheet 516 is fixedly connected to the inner wall of the adjusting plate 513, a push rod 517 is slidably connected to the outer side of the baffle 515, one end of the push rod 517 is fixedly connected to the limit block 59, and an oblique end 518 is opened at one end of the baffle 515 close to the push rod 517;

[0046] If the deformation block 45 between the moving plate 44 and the top of the moving box 40 begins to melt, the movement of the sliding plate 53 will not drive the push rod 517 to squeeze the baffle 515, the adjustment hole 514 will not be blocked, and the airflow can pass through the adjustment hole 514 on the inner wall of the adjustment plate 513 normally;

[0047] If the deformation block 2 413 between the moving box 40 and the top of the supporting box 3 also starts to melt, the sliding plate 53 moves to drive the limit block 59 to move, and the limit block 59 drives the push rod 517 to move, and the push rod 517 squeezes the oblique end 518 of the baffle 515 to push the baffle 515 to slide along the inner wall of the adjustment plate 513, and the two baffles 515 are close to each other to block the adjustment hole 514, so that the area where the airflow can pass through the adjustment plate 513 is reduced;

[0048] When the temperature drops, the sliding plate 53 is reset, the sliding plate 53 drives the limit block 59 to reset, and the limit block 59 drives the push rod 517 to move, so that the push rod 517 no longer squeezes the baffle 515, and the spring sheet 516 in the compressed state pushes the baffle 515 to reset, and the two baffles 515 no longer block the adjustment hole 514.

[0049] The closing member 58 includes an adjusting rod 519 located on the inner wall of the ventilation hole 57, a supporting frame 520 located on the outer side of the adjusting rod 519, the adjusting rod 519 is rotatably connected to the inner wall of the supporting frame 520, the supporting frame 520 is fixedly connected to the inner wall of the ventilation hole 57, threaded rods 521 are fixedly connected to both ends of the adjusting rod 519, a closing block 522 is threadedly connected to the outer side of the threaded rod 521, at normal temperature, the closing block 522 closes the ventilation hole 57 to reduce wind resistance, a slider 523 is fixedly connected to the outer side of the closing block 522, a sliding groove 524 which can be slidably connected to the slider 523 is provided on the inner wall of the ventilation hole 57, a transmission gear 1 525 is fixedly connected to the center of the adjusting rod 519, a transmission chain 526 is meshed on the outer side of the transmission gear 1 525, and a transmission gear 2 527 is meshed at one end of the transmission chain 526. The transmission gear 2 527 is rotatably connected to the inner wall of the clamping block 2, and one end of the transmission gear 2 527 is fixedly connected to a driving gear 528, and one end of the driving gear 528 is rotatably connected to the inner wall of the clamping block 2. A driving plate 529 is provided on the outer side of the driving gear 528, and the driving plate 529 is slidably connected to the inner wall of the clamping block 2. A rack portion 530 is provided on the surface of the driving plate 529, and one end of the driving plate 529 is fixedly connected to the sliding plate 53. When the deformation block 1 45 located between the moving plate 44 and the top of the moving box 40 begins to melt, the movement of the driving plate 529 will not drive the driving gear 528 to rotate, and when the deformation block 2 413 located between the moving box 40 and the top of the supporting box 3 also begins to melt, the rack portion 530 of the driving plate 529 will mesh with the driving gear 528 and drive the driving gear 528 to rotate;

[0050] If the deformation block 2 413 between the moving box 40 and the top of the supporting box 3 also begins to melt, the piston plate 47 slides downward along the inner wall of the connecting groove 48 to push the sliding plate 53 to move. Since the adjusting hole 514 on the inner wall of the adjusting plate 513 is partially blocked, a part of the airflow in the air inlet 52 will enter the ventilation hole 57 through the gap in the inner wall of the clamping block 2, and blow to the wire on the inner wall of the clamping block 2 through the ventilation hole 57, thereby improving the heat dissipation of the wire. In addition, the movement of the sliding plate 53 will drive the driving plate 529 to move, and the rack portion 530 of the driving plate 529 will mesh with the driving gear 528 and drive the driving gear 528 to rotate. The driving gear 528 drives the transmission gear 2 527 to rotate, the transmission gear 2 527 drives the transmission chain 526 to rotate, the transmission chain 526 drives the transmission gear 1 525 to rotate, the transmission gear 1 525 drives the adjusting rod 519 to rotate, the adjusting rod 519 drives the threaded rod 521 to rotate, so that the closing blocks 522 on both sides move outward, the closing blocks 522 drive the slider 523 to slide along the inner wall of the slide groove 524, so that the closing blocks 522 release the blockage of the ventilation holes 57, and the external airflow can be directly blown to the wires on the inner wall of the clamping block 2 through the ventilation holes 57, thereby enhancing the heat dissipation of the wires and extending the processing response time for the staff.

[0051] Embodiment 2

[0052] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the first deformation block 45 and the second deformation block 413 can also be shape memory metals. For shape memory metals, they have a specific phase transition temperature, such as nickel-titanium alloy. The shape memory effect principle of nickel-titanium alloy is based on the martensitic phase transition of the metal. The nickel-titanium alloy will transform from a high-temperature phase (austenite) to a low-temperature phase (martensite) during the cooling process. When the nickel-titanium alloy is heated to a certain temperature, it will transform from a low-temperature phase to a high-temperature phase, that is, from a martensite phase to an austenite phase. During this transformation process, the nickel-titanium alloy will restore its original shape.

[0053] The phase transition temperature of nickel-titanium metal can be controlled by adjusting the ratio of nickel and titanium in the alloy. Generally speaking, the higher the nickel content, the lower the phase transition temperature; the higher the titanium content, the higher the phase transition temperature. Therefore, deformation block 1 45 and deformation block 2 413 can also use nickel-titanium metals with different phase transition temperatures to achieve the same effect.
