AI Technical Summary
The existing parallel groove clamps cannot sense their own temperature in time, which makes it impossible for staff to judge whether the shell is hot in time. Manual temperature measurement is required. In addition, the wires are prone to loosening due to thermal expansion and contraction in high temperature environments.
A bimetallic strip is built into the parallel groove clamp. Its thermal expansion effect drives the limit strip to move, releasing the limit on the indicator rod, making the indicator rod protrude to indicate high temperature. The cooperation of the receiving strip and the abutment strip ensures that the conductor is stable in the high temperature environment.
It enables real-time monitoring of the temperature of the parallel groove clamps and secure fixation of the conductors, reducing the need for manual temperature measurement and the risk of loosening of the conductors due to thermal expansion and contraction.

TECHNICAL FIELD
[0001] The present application relates to the technical field of wire clamps, and particularly to a temperature measuring parallel groove wire clamp. BACKGROUND
[0002] The temperature measuring parallel groove wire clamp is a special wire clamp integrating power hardware and temperature monitoring functions. On the basis of a traditional wire connecting hardware (such as a C-shaped or U-shaped wire clamp), a temperature sensing element (bimetallic strip, thermocouple or thermosensitive metal strip) is built in, and an over-temperature indicating device or a wireless / wired alarm system is provided, so as to realize real-time monitoring and early warning of the temperature of the wire clamp body and adjacent wires.
[0003] In the related art, the parallel groove wire clamp includes a shell, a clamping block is threadedly connected to the shell, and a placing groove for placing a wire is formed in the shell. The clamping block can clamp the wire through bolts, so that the wire can be fixed to the parallel groove wire clamp.
[0004] In a high temperature season, the ambient temperature is high. At this time, the parallel groove wire clamp absorbs the temperature of the outside world and transmits the high temperature to the wire. 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 wire begin to vibrate, causing slight expansion. This expansion will cause the length of the wire to increase, and the cross-sectional area of the wire to decrease, that is, the wire will be elongated into a slender shape, so that the wire is more likely to extend to both sides and the cross-sectional area decreases when it expands and contracts.
[0005] In a high temperature season, the staff needs to strengthen the inspection and maintenance of the wire. The parallel groove wire clamp cannot timely sense its own temperature, and the staff needs to detect the temperature of the shell in a high temperature, so that the staff cannot timely determine whether the shell is in a high temperature condition. SUMMARY
[0006] In order to improve the problem that the staff cannot timely determine whether the shell is in a high temperature, the present application provides a temperature measuring parallel groove wire clamp.
[0007] The temperature measuring parallel groove wire clamp provided by the present application adopts the following technical scheme: A temperature measuring parallel groove wire clamp includes a shell, a clamping block is threadedly connected to the shell, and a placing groove for placing a wire is formed in the shell. The clamping block can clamp the wire through bolts, so that the wire can be fixed to the parallel groove wire clamp. When the limiting strip is separated from the limiting hole, the containing spring pushes the indicating rod out of the containing groove.
[0008] By adopting the above technical scheme, when the bimetallic strip is too high in temperature, the bimetallic strip can drive the limiting strip to move, so that the limiting strip can be separated from the limiting hole, the limiting of the indicating rod by the limiting strip is released, and the indicating rod can be protruded from the accommodating slot by the accommodating spring; whether the indicating rod is protruded or not can indicate whether the temperature of the wire clamp is too high, if the temperature is too high, the staff can tighten the clamping block and push the indicating rod to reset, at this time, since the temperature in the shell is still too high, the bimetallic strip still drives the limiting strip to move, so that the limiting strip cannot be located in the limiting hole, so that the staff cannot realize that the indicating rod is stably located in the accommodating slot, and the staff can know that the temperature of the shell is still too high; when the temperature of the shell is low, the indicating rod is located in the accommodating slot, at this time, the reset member can drive the limiting strip to reset, so that the limiting strip can be smoothly inserted into the limiting hole, and the limiting of the indicating rod by the limiting strip is realized.
[0009] Optionally, the bimetallic strip is provided with a connecting strip, the limiting strip is provided with a connecting hole for inserting the connecting strip, a connecting inclined surface is formed in the hole wall of the connecting hole away from the limiting hole, the distance between the connecting inclined surface and the limiting hole gradually decreases in the direction from the bimetallic strip to the connecting strip, and the connecting inclined surface is located in the movement path of the connecting strip inserted into the connecting hole.
[0010] By adopting the above technical scheme, when the temperature of the bimetallic strip is too high, the bimetallic strip can drive the connecting strip to move, the connecting strip drives the limiting strip to move through the connecting inclined surface, and the limiting strip can be separated from the limiting hole, so as to release the mutual fixation of the limiting strip and the indicating rod.
[0011] Optionally, a plurality of abutting strips are slidably connected to the placing slot, the abutting strips are used for abutting the wires, and a containing strip is slidably connected to the shell and used for lifting the abutting strips to press the wires.
[0012] By adopting the above technical scheme, since the temperature of the external environment is high, the indicating rod protrudes from the accommodating slot at this time, the external environment causes the temperature of the wire to be high, the cross-sectional area of the wire is reduced, and the length of the wire is increased, so that the clamping block and the slot wall of the placing slot are difficult to directly clamp the wire, the staff can slide the containing strip, the containing strip can lift the abutting strips, the abutting strips can press the wire, and the wire can be fixed to the shell.
[0013] Optionally, the movement path of the limiting strip separated from the limiting hole intersects with the movement path of the containing strip lifting the abutting strips, a containing inclined surface is formed in the containing strip, and the distance between the containing inclined surface and the wire gradually increases in the direction from the limiting strip to the containing strip.
[0014] By adopting the above technical scheme, since the moving path of the limiting strip disengaging from the limiting hole and the moving path of the accommodating strip lifting the abutting strip intersect, the limiting strip can drive the accommodating strip to move, and the accommodating strip drives the abutting strip to move through the accommodating inclined surface, so that the abutting strip can abut against the conductor; when the external environment temperature decreases, the conductor restores the original cross-sectional area, and if the staff uses the method of rotating the bolt to move the clamping block to fix the conductor, the conductor may be damaged, affecting the normal use of the conductor; when the external environment decreases, the conductor restores the original cross-sectional area, and since the bimetallic strip resets, the bimetallic strip does not abut against the connecting strip at this time, the limiting strip can be reset through the reset member, so that the limiting strip will not continue to abut against the accommodating strip, and at this time the conductor can push the abutting strip to reset, so that the abutting strip can fall down, so that the conductor reset will not be damaged, reducing the possibility of conductor damage caused by large day-night temperature difference.
[0015] Optionally, the clamping block is provided with a rotating shaft, and a stopper strip is rotatably connected to the rotating shaft, and the stopper strip is used to press the side of the conductor away from the abutting strip.
[0016] By adopting the above technical scheme, the staff rotates the stopper strip, so that the stopper strip can smoothly abut against the side of the conductor away from the abutting strip, so that the conductor can be limited by the abutting strip and the stopper strip, further increasing the firmness of the conductor on the shell.
[0017] Optionally, one end of the stopper strip is provided with an abutting portion for pressing the conductor, and the other end of the stopper strip is provided with a moving portion, a linkage strip is slidably connected to the placing groove, the moving path of the linkage strip intersects with the moving path of the accommodating strip, and the moving path of the linkage strip intersects with the rotating path of the moving portion; when the accommodating strip lifts all the abutting strips, the accommodating strip can drive the linkage strip to lift.
[0018] By adopting the above technical scheme, when the accommodating strip lifts all the abutting strips, the accommodating strip can smoothly drive the linkage strip to lift up, because the moving path of the linkage strip intersects with the moving path of the accommodating strip; the linkage strip can drive the moving part to rotate, because the moving path of the linkage strip intersects with the rotating path of the moving part; the rotating part drives the abutting part to move through the rotating shaft, so that the abutting part can smoothly abut against the outer surface of the wire; if the temperature of the shell is not high, the accommodating strip can drive part of the abutting strips to lift up, so that the abutting strips can smoothly limit the movement of the wire through the lifting of the part of the abutting strips; if the temperature of the shell gradually increases, the accommodating strip can drive all the abutting strips to move, so that all the abutting strips can stably limit the movement of the wire on the shell; at this time, the limiting strip can be separated from the limiting hole; if the temperature of the shell further increases, the cross-sectional area of the wire will further decrease; at this time, the accommodating strip drives the moving part to move through the linkage strip, so that the abutting part can smoothly abut against the wire, thereby stably fixing the wire on the shell, and reducing the possibility that the wire may move in the placing groove due to continuous temperature rise.
[0019] Optionally, the abutting part is provided with an abutting groove for abutting against the outer surface of the wire, and an elastic block is arranged on the groove wall of the abutting groove away from the rotating shaft, and the elastic block is used for abutting against the outer surface of the wire.
[0020] By adopting the above technical scheme, when the limiting strip rotates, the groove wall of the abutting groove abuts against the outer surface of the wire, and at this time, the elastic block can abut against one side of the wire, so that the elastic block can stably abut against the wire, because the cross-sectional area of the wire further decreases, and at this time, there may be a gap between the wire and the abutting strip, and the elastic block is extruded towards the abutting strip, so that the wire can be more stably located between the abutting strip and the limiting strip.
[0021] Optionally, the limiting strip is provided with a first magnet, and the accommodating strip is provided with a second magnet for attracting the first magnet; when the limiting strip is inserted into the limiting hole, the accommodating strip does not lift the abutting strips.
[0022] By adopting the above technical scheme, when the limiting strip is inserted into the limiting hole, the first magnet drives the second magnet to move, so that the second magnet drives the accommodating strip to move, so that the accommodating strip does not lift the abutting strips; when the temperature decreases and the wire resets, the abutting strips do not continue to extrude the wire.
[0023] In summary, the present application has at least one of the following beneficial technical effects: 1. When the bimetallic strip is arranged in the moving groove, the bimetallic strip can drive the limiting strip to move when the temperature of the bimetallic strip is too high, so that the limiting strip can be separated from the limiting hole, the limiting of the indicating rod by the limiting strip is released, the indicating rod can be driven by the containing spring to protrude from the containing groove; whether the indicating rod protrudes or not can indicate whether the temperature of the wire clamp is too high, if the temperature is too high, the worker can tighten the clamping block and push the indicating rod to reset, at this time, the temperature in the shell is still too high, so that the bimetallic strip still drives the limiting strip to move, so that the limiting strip cannot be located in the limiting hole, so that the worker cannot realize the stable location of the indicating rod in the containing groove, and the worker can know that the temperature of the shell is still too high; when the temperature of the shell is low, the indicating rod is located in the containing groove, at this time, the reset member can drive the limiting strip to reset, so that the limiting strip can be smoothly inserted into the limiting hole, and the limiting of the indicating rod by the limiting strip is realized.

A plurality of clamping blocks 2 are bolted to the shell 1, and the slot wall of the placement slot 11 is used for clamping the wire.
[0029] Referring to Figure 2 A containing groove 12 is formed in the side surface of the shell 1, a containing spring 121 is fixedly connected to the bottom wall of the containing groove 12, an indicating rod 122 is fixedly connected to the surface of the containing spring 121 away from the bottom wall of the containing groove 12, and the containing spring 121 pushes the indicating rod 122 to protrude out of the containing groove 12. When the indicating rod 122 protrudes out of the containing groove 12, the containing spring 121 is in a non-stressed state; when the indicating rod 122 is located in the containing groove 12, the containing spring 121 is in a compressed state.
[0030] Referring to Figure 3 A moving groove 13 is formed in the shell 1 and communicates with the containing groove 12, and the length direction of the moving groove 13 is perpendicular to the length direction of the containing groove 12. A limiting strip 131 is slidingly connected in the moving groove 13, and a limiting hole 123 is formed in the outer surface of the indicating rod 122 for inserting the limiting strip 131. When the limiting strip 131 is inserted into the limiting hole 123, the indicating rod 122 can be fixed in the containing groove 12, and at this time, the indicating rod 122 does not protrude out of the containing groove 12.
[0031] Referring to Figure 3The surface of the limiting strip 131 is fixedly connected with a limiting block 132, and the limiting block 132 is provided with a reset member 133, which is used to drive the limiting strip 131 to be inserted into the accommodating groove 12. The reset member 133 comprises a reset spring arranged on the limiting block 132. When the limiting block 132 is inserted into the accommodating groove 12, the reset spring is in a non-stressed state. When the limiting block 132 is completely located in the moving groove 13, the reset spring is in a compressed state.
[0032] With reference to Figure 4 The groove wall of the moving groove 13 is provided with an accommodating cavity, and the accommodating cavity is fixedly connected with a bimetallic strip 141. The material of the bimetallic strip 141 is manganese-nickel-copper alloy and invar alloy. When the bimetallic strip 141 is subjected to 70 degrees Celsius, the bimetallic strip 141 may be deformed.
[0033] With reference to Figure 3 And Figure 4 The accommodating cavity is slidably connected with a connecting strip 142, and the connecting strip 142 can be inserted into the moving groove 13. The surface of the limiting strip 131 is provided with a connecting hole 143, and the connecting hole 143 is used for the insertion of the connecting strip 142. The connecting hole 143 is provided with a connecting inclined surface 144 on the hole wall away from the indicating rod 122. The distance between the connecting inclined surface 144 and the indicating rod 122 gradually decreases in the direction from the bimetallic strip 141 to the limiting strip 131, and the connecting inclined surface 144 is located on the insertion path of the connecting strip 142 inserted into the connecting hole 143. The action force of the deformed bimetallic strip 141 on the connecting strip 142 is greater than the action force of the reset spring on the limiting block 132, that is, the bimetallic strip 141 can drive the limiting strip 131 to be separated from the accommodating groove 12 through the connecting strip 142.
[0034] With reference to Figure 3 And Figure 4 When the temperature of the shell 1 is higher than 70 degrees Celsius, the bimetallic strip 141 is deformed, and the bimetallic strip 141 can drive the connecting strip 142 to be inserted into the connecting hole 143. The connecting strip 142 drives the limiting strip 131 to move through the connecting inclined surface 144, so that the limiting strip 131 can be separated from the limiting hole 123, the indicating rod 122 is unlocked by the limiting strip 131, and the accommodating spring 121 can drive the indicating rod 122 to protrude from the accommodating groove 12.
[0035] With reference to Figure 5The moving groove 13 is communicated with the placing groove 11, a plurality of accommodation strips 15 are slidably connected in the moving groove 13, each accommodation strip 15 can be inserted into different placing grooves 11 from the moving groove 13, a plurality of accommodation strips 15 are fixedly connected with a connecting plate, and the connecting plate is used for realizing mutual fixation of the plurality of accommodation strips 15. A second magnet 152 is fixedly connected to an end surface of the accommodation strip 15, a first magnet 151 is fixedly connected to an end surface of the limiting strip 131 away from the indicating rod 122, and the first magnet 151 and the second magnet 152 can be mutually adsorbed. The sliding path of the limiting strip 131 and the sliding path of the accommodation strip 15 intersect, that is, the limiting strip 131 can drive the plurality of accommodation strips 15 to slide together through the connecting plate.
[0036] With reference to Figure 5 A plurality of abutting strips 16 are slidably connected in the placing groove 11, the abutting strips 16 have elastic deformation capacity, the plurality of abutting strips 16 are arrayed along the width direction of the placing groove 11, and the abutting strips 16 can slide along the vertical direction. An accommodation inclined surface 153 is formed on an end surface of the accommodation strip 15 away from the limiting strip 131, and the distance between the accommodation inclined surface 153 and the limiting strip 131 gradually increases in the vertical downward direction. The sliding path of the accommodation inclined surface 153 inserted into the placing groove 11 intersects with the lifting path of the abutting strip 16.
[0037] With reference to Figure 3 And Figure 5 When the bimetallic strip 141 reaches 70 degrees Celsius, the limiting strip 131 can drive the accommodation strip 15 to slide, so that the accommodation strip 15 drives the abutting strip 16 to lift through the accommodation inclined surface 153. As the temperature continues to rise, the deformation amount of the bimetallic strip 141 gradually increases, so that the bimetallic strip 141 drives the limiting strip 131 to continue to move through the connecting strip 142, so that the limiting strip 131 drives the accommodation strip 15 to continuously slide, that is, the accommodation strip 15 can drive all the abutting strips 16 to lift, so that the abutting strips 16 can abut against the surface of the wire close to the ground, so that the wire can be stably located between the clamping block 2 and the abutting strip 16. At this time, the limiting strip 131 can be separated from the limiting hole 123.
[0038] With reference to Figure 5 A rotating shaft 21 is fixedly connected to the surface of the clamping block 2 close to the ground, a stop strip 22 is rotatably connected to the rotating shaft 21, and the stop strip 22 can be rotated towards the direction from the clamping block 2 to the groove wall of the placing groove 11. One end of the stop strip 22 is an abutting portion 224, the other end of the stop strip 22 is a moving portion 225, and the abutting portion 224 and the moving portion 225 are located on different sides of the rotating shaft 21. The abutting portion 224 is used for abutting against the wire, and the moving portion 225 is used for driving the abutting portion 224 to rotate towards the wire.
[0039] With reference to Figure 3 And Figure 5The abutting part 224 is provided with an abutting groove 221 on the surface close to the placing groove 11, the abutting groove 221 is used for abutting the surface of the wire, and the elastic block 222 is fixedly connected to the groove wall of the abutting groove 221. The linkage strip 223 is slidingly connected to the placing groove 11, and the linkage strip 223 is located on the side, away from the indicating rod 122, of all the abutting strips 16. The sliding path of the linkage strip 223 intersects with the sliding path of the containing strip 15, and the sliding path of the linkage strip 223 intersects with the rotating path of the moving part 225.
[0040] With reference to Figure 3 And Figure 5 When the limiting strip 131 is disengaged from the limiting hole 123, the containing strip 15 drives the abutting strip 16 to lift, and with the continuous deformation of the bimetallic strip 141, the containing strip 15 continuously moves, so that the containing strip 15 drives the linkage strip 223 to move through the containing slope 153, and the linkage strip 223 drives the stop strip 22 to rotate, so that the elastic block 222 abuts against the outer surface of the wire. Due to the temperature rise, the cross-sectional area of the wire may further decrease, so that the elastic block 222 can abut against the wire, and the wire can abut against the abutting strip 16, the elastic block 222 and the groove wall of the abutting groove 221, so as to further fix the wire.
[0041] The implementation principle of the temperature measurement type parallel groove wire clamp is that when the temperature of the shell 1 rises, the bimetallic strip 141 deforms, the bimetallic strip 141 drives the connecting strip 142 to slide, the connecting strip 142 drives the limiting strip 131 to move through the connecting slope 144, the limiting strip 131 drives the containing strip 15 to slide, and the containing strip 15 lifts the abutting strip 16 through the moving slope. With the continuous temperature rise of the shell 1, the bimetallic strip 141 continues to deform, so that the containing strip 15 can continuously move, and the abutting strip 16 is lifted. At this time, the limiting strip 131 can be disengaged from the limiting hole 123, and the containing spring 121 drives the indicating rod 122 to protrude from the containing groove 12. With the continuous temperature rise of the shell 1, the containing strip 15 drives the linkage strip 223 to move through the containing slope 153, and the linkage strip 223 drives the abutting part 224 to rotate through the moving part 225, so as to abut against the wire.
