Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire temperature measurement, in particular to a wire temperature measurement installation and detection method. BACKGROUND

[0002] At present, the installation and detection of wire temperature in the industry is basically to use a right-angle installation piece to fix the line temperature sensor on the fixing bolt of the strain clamp drainage plate. The line temperature sensor is a non-contact temperature detection device. In the installation process, power supply needs to be stopped, the original bolt of the strain clamp drainage plate needs to be removed, and then the bolt is fastened after the right-angle installation piece is installed. The loss of power supply installation is large, and the installation process is complex. The bolt connection is not tight, which may also cause destructive consequences. Such a traditional method cannot meet the needs of transmission line operation and maintenance monitoring.

[0003] With the development of related technologies, a line clamp temperature rise monitoring device for high-voltage live installation is disclosed in Chinese Patent No. CN209525015U. The device includes a temperature probe, a bracket, a movable pressure plate, a spring, and an anti-falling block. The temperature probe is arranged on the right-angle bracket. One end of the right-angle bracket is connected to the movable pressure plate, and the other end is connected to the anti-falling block. The movable pressure plate and the bracket are connected through a fixed shaft. The spring is arranged between the bracket and the movable pressure plate. This technology realizes the live installation of the temperature measurement sensor without changing the electrical connection of the line clamp and without stopping the power supply of the line. It provides a new iterative technology for traditional indirect detection and power-off installation. The installation tool for the line clamp temperature rise monitoring device is also provided, which includes a mounting frame, a fixing piece matched with the temperature probe, and a fixing groove matched with the movable pressure plate. The fixing groove is connected to the bottom of the mounting frame. The top of the mounting frame is provided with a universal joint. The installation tool is matched with the corresponding line clamp temperature rise monitoring device, which can realize the fixation of the line clamp temperature rise monitoring device on the wire or the hardware under the condition of uninterrupted power supply.

[0004] In the patent technology, the clamp holding of the wire is realized by the movable pressure plate, which clamps the line clamp between the bracket and the movable pressure plate, so as to fix the monitoring tool on the line clamp. In order to further prevent the temperature measurement sensor from sliding and falling horizontally, the anti-falling block is designed. The clamp fixation of the line clamp in the patent technology has poor anti-falling stability, and the installation and fixation structure is complex, which also increases the installation time to some extent. The installation tool in the patent technology is matched with the line clamp temperature rise monitoring device.

[0005] Therefore, a new wire temperature measurement installation and detection method is needed. SUMMARY

[0006] In order to solve the above technical problems, the present application provides a wire temperature measurement installation and detection method.

[0007] The application provides a kind of installation detection method of lead temperature measurement, adopt the technical scheme as follows:

[0008] An installation detection method of lead temperature measurement, the installation detection method involves the components used have lead temperature measurement sensor and installation structure for installing lead temperature measurement sensor on the lead, characterized in that: the lead temperature measurement sensor includes open attitude and tight attitude, open attitude is the installation state, the first clamp and the second clamp of the lead temperature measurement sensor are relatively open away from each other under the action of external force, tight attitude is the detection state of holding the lead, the first clamp and the second clamp of the lead temperature measurement sensor are relatively close to each other under the action of self torsion spring reset;

[0009] The installation detection method of lead temperature measurement includes the following steps:

[0010] Step 1) limit the installation of lead temperature measurement sensor required for lead temperature measurement detection in open attitude on the vertical top of the installation structure;

[0011] Step 2) under the condition that the lead is continuously powered, use the installation structure to lift the lead temperature measurement sensor to the lower side of the lead;

[0012] Step 3) use the relative rotation of the installation structure itself to adjust the relative position of the lead temperature measurement sensor and the lead in open attitude, so that the first clamp and the second clamp of the lead temperature measurement sensor can normally hold the lead after being separated from the limit of the installation structure;

[0013] Step 4) after adjusting the relative position of the lead temperature measurement sensor and the lead, continue to lift the installation structure so that the upper end of the lead temperature measurement sensor is in contact with the vertical lower end surface of the lead;

[0014] Step 5) continue to apply the lifting force with the vertical lower end of the installation structure, so that the lead reacts on the lead temperature measurement sensor to compress the cavity at the top of the installation structure, the lead temperature measurement sensor descends in the cavity at the top of the installation structure, providing deformation space for the lead temperature measurement sensor to change from open attitude to tight attitude at the top of the installation structure, continue to lift, the deformation space increases, until the lead temperature measurement sensor is completely separated from the limit installation at the top of the installation structure, the first clamp and the second clamp of the lead temperature measurement sensor quickly hold the lead, at this time the lead temperature measurement sensor and the installation structure are separated, and the lead temperature measurement sensor performs contact type temperature measurement detection on the lead.

[0015] By adopting the above-mentioned technical solution, the present application utilizes the clamping posture of the first and second clamps to flexibly and snugly hold the wire, realizing a novel contact-type direct wire temperature measurement. Furthermore, the mounting structure's top limiter, the cavity-provided deformation space, and the relative rotational adjustment of the clamping position all work together to achieve simple, safe, and quick live-wire installation of the wire temperature sensor. The simple structure and easy coordination of the two allow the wire temperature sensor to effectively hold the wire and resist falling off.

[0016] Optionally, in step 1, the first clamp and the second clamp on the wire temperature sensor are opened under the action of external force, and are limitedly installed in two relatively arranged limit slots at the vertical top of the installation structure, wherein one limit slot is limit-installed on one end of the first clamp, and the other limit slot is limit-installed on one end of the second clamp, thereby completing the open posture of the wire temperature sensor in the limited installation.

[0017] By adopting the above technical solution, the opened first clamp and the second clamp can be limited and installed in the limit slot and kept open. As long as there is no external force to deform them, the first clamp and the second clamp can be firmly limited in the two limit slots with simple structure. The limiting slots are simple to limit, and the limiting installation of the first clamp and the second clamp is also simple, so the separation process of the two will also be smooth.

[0018] Optionally, in step 1, the first clamp or the second clamp is connected in sequence using a multi-section connecting rod to increase the tight fit of the first clamp or the second clamp to the wire. A rotation connection is adopted between two adjacent connecting rods of the first clamp or the second clamp, and a torsion spring is added at each rotation connection. In the open state, the torsion spring is stretched under the action of external force, and the connecting rods of the first clamp are stretched along the length direction of the first clamp, and the connecting rods of the second clamp are stretched along the length direction of the second clamp. When transitioning from the open state to the clamping state, the limiting effect of the vertical top of the mounting structure is gradually eliminated, and the torsion spring is opened and reset. Under the reset force of the torsion spring, the connecting rods of the first clamp rotate relative to each other, and the connecting rods of the second clamp also rotate relative to each other. The first clamp is held toward the second clamp, and the second clamp is held toward the first clamp. Finally, the first clamp and the second clamp form a closed enclosure and are tightly held on the outer wall of the wire.

[0019] By adopting this technical solution, the multi-section connecting rod structure of the first or second clamp can better fit the outer wall of the wire. Under the action of the torsion spring, it can also be more securely held on the outer wall of the wire, and it is not easy to fall off. The rotating connection method ensures that the first or second clamp can be naturally and smoothly clamped under the force of the torsion spring.

[0020] Optionally, the first clamp and the second clamp are oppositely arranged and connected with one end of the temperature sensor body through the mounting base, the first clamp and the second clamp are arranged on the end of the mounting base away from the temperature sensor body, the temperature sensor body is used for detecting the temperature of the wire, and the first clamp and the second clamp fix the temperature sensor body on the wire by tightly holding the wire, and directly contact the wire to detect the temperature.

[0021] By adopting the above technical solution, the first clamp and the second clamp are oppositely arranged on the end of the mounting base away from the temperature sensor body, and can form a continuous length direction extension in the open state, which is convenient for checking and confirming the position in the length direction of the wire. In the tight state, the first clamp and the second clamp can form a surrounding on the outer wall of the wire as much as possible in the same plane to increase the tightness. The temperature sensor body and the first clamp are arranged at the two ends of the mounting base respectively, so as to better cooperate with the installation structure cavity and the top limiting installation, that is, the top limiting installation is fixedly connected at the end edge of the cavity, the first clamp is used in cooperation with the limiting slot of the top limiting installation, and the temperature sensor body extends into the cavity. The cooperation between the first clamp and the limiting slot, the cooperation between the cavity and the temperature sensor body, and the spatial position arrangement between the cavity and the limiting slot, the temperature sensor body and the first clamp, the temperature sensor body and the second clamp, and the first clamp and the second clamp can more stably limit the installation of the first clamp and the second clamp, and can provide deformation space for the disengagement of the limiting installation.

[0022] Optionally, the mounting base limits the rotating positions of the first clamp and the second clamp through two mounting slots, the first clamp and the second clamp are respectively provided with limiting slots for limiting the stretching of the torsion spring and limiting the rotating positions of the adjacent two connecting rods on the first clamp or the second clamp. When the torsion spring is stretched, the adjacent two connecting rods on the first clamp or the second clamp are stretched to the open state, and when the torsion spring is reset, the adjacent two connecting rods on the first clamp or the second clamp are tightly held to the outer wall of the wire to reach the tight state.

[0023] By adopting the above technical solution, the limiting slot, the rotating connection and the torsion spring are used in cooperation, which can not only ensure the relative opening of the first clamp and the second clamp, but also limit the opening to prevent the deformation of the direction in the limiting slot of the installation structure, and can provide the stretching force for the torsion spring in the limiting installation. Finally, under the reset action of the torsion spring, the first clamp and the second clamp tightly hold the wire. The mounting slot, the rotating connection and the torsion spring are used in cooperation, which is the same as the above-mentioned function of the limiting slot. Moreover, in the above-mentioned function, the limiting slot and the mounting slot are in cooperation, and the first clamp and the second clamp cannot tightly hold the wire without the mounting slot.

[0024] Optionally, in the step 2), in order to install the wire temperature sensor without power-off of the wire, the connecting member with the universal joint at the vertical bottom end of the installation structure is made of insulating material, thereby cutting off the risk of contact between the wire temperature sensor and the wire in the subsequent step.

[0025] By adopting the above technical scheme, the installation structure is simple, the holding structure is simple, the holding effect is good, and the installation is fast and convenient. However, the safety guarantee is indispensable for live installation, so it is particularly important to design the vertical bottom end of the installation structure as an insulating material.

[0026] Optionally, in the step 3, the relative rotation of the installation structure itself refers to that the connecting member is provided with a circular hole on the mounting seat, the connecting member is provided with a connecting cylinder at one end extending into the circular hole, the connecting cylinder is relatively rotated in the circular hole, and the wire temperature sensor is below the wire and is limited by the wire, thereby completing the rotation of the connecting member and adjusting the relative position of the first clamp, the second clamp and the wire length direction of the wire temperature sensor.

[0027] By adopting the above technical scheme, the relative rotation of the installation structure itself can be simply and quickly realized through the design of the circular hole and the connecting cylinder, and finally the positions of the first clamp and the second clamp relative to the wire are simply and quickly adjusted. After the first clamp and the second clamp are separated from the limiting installation, they can more stably and firmly hold the wire.

[0028] Optionally, in the step 5, in order to stably limit and install the wire temperature sensor in the open state, a spring is further arranged in the cavity, a baffle is further arranged between the spring and the wire temperature sensor, and a snap ring is further arranged at the end port of the cavity close to the wire temperature sensor. In the open state, the end of the wire temperature sensor away from the first clamp extends into the cavity at the top of the installation structure, the baffle is pushed down, the spring is compressed, and when the lifting force is continuously applied, the wire temperature sensor continuously pushes down the baffle in the cavity and compresses the spring. At this time, the first clamp or the second clamp starts to deform under the action of the spring reset, and as the wire temperature sensor goes down more and more, that is, the temperature sensor body on the wire temperature sensor goes away from the vertical top of the installation structure more and more, the deformation space of the first clamp or the second clamp also becomes larger and larger. When the first clamp or the second clamp holds the wire more and more tightly, the first clamp or the second clamp finally separates from the vertical top of the installation structure and holds the outer side wall of the wire.

[0029] Through the above technical scheme, the process is described in detail from the open state to the holding state, the activity change of the lead temperature measurement sensor and the mounting structure, and the activity change of the two. The installation process is simple and fast. The cooperation of the cavity, the spring, the baffle and the snap ring on the cavity edge provides installation space for the temperature measurement sensor body, and helps to improve the limiting stability of the first clamp and the second clamp in the limiting clamping groove under the action of the spring. When installing, the temperature measurement sensor body pushes down the baffle to compress the spring under the resistance of the lead, increasing the distance between the temperature measurement sensor body and the limiting clamping groove, i.e. the deformation space of the first clamp and the second clamp.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The installation detection method of the present application adopts the holding state of the first clamp and the second clamp to hold the lead very flexibly and closely, realizes the direct temperature measurement of the new contact type lead, and realizes the simple, safe and fast live-line installation of the lead temperature measurement sensor by the combined action of the top limiting installation of the mounting structure, the deformation space provided by the cavity and the relative rotation adjustment of the holding position. The two structures involved in the installation detection method of the present application are simple and convenient to cooperate, the holding effect of the lead temperature measurement sensor on the lead is good, and it is not easy to fall off;

[0032] 2. The installation detection method of the present application can limit the installation of the first clamp and the second clamp in the limiting clamping groove. The limiting of the limiting clamping groove is simple, and the limiting installation of the first clamp and the second clamp is also simple, so the separation process of the two is also very smooth, which improves the efficiency of the installation process in the installation detection method;

[0033] 3. The first clamp or the second clamp in the installation detection method of the present application adopts a multi-section connecting rod structure, which can better fit on the outer side wall of the lead, improve the detection effect, and also can be more stable on the outer side wall of the lead under the action of the torsion spring, not easy to fall off, further improve the detection effect and fixing stability. The rotary connection mode ensures that the first clamp or the second clamp can naturally and smoothly realize holding under the action of the torsion spring, further improves the installation efficiency and detection effect.

DETAILED DESCRIPTION

[0040] The application will be further described in detail below in combination with all the drawings.

[0041] The application discloses a wire temperature measurement installation and detection method.

[0042] Reference Figures 1-5 A wire temperature measurement installation and detection method, which involves the use of a wire temperature measurement sensor and an installation structure for installing the wire temperature measurement sensor on a wire. The wire temperature measurement sensor includes an open state and a holding state. In the open state, i.e. the installation state, the first clamp 18 and the second clamp 19 of the wire temperature measurement sensor are relatively open and away from each other under the action of an external force. In the holding state, i.e. the detection state of holding the wire, the first clamp 18 and the second clamp 19 of the wire temperature measurement sensor are relatively close to each other under the action of the self-torsion spring reset.

[0043] The wire temperature measurement installation and detection method includes the following steps:

[0044] Step 1) Limiting the wire temperature measurement sensor required for wire temperature measurement detection in an open state on the vertical top of the installation structure.

[0045] Step 2) Under the condition that the wire is continuously powered, use the installation structure to lift the wire temperature measurement sensor to the lower side of the wire.

[0046] Step 3) Adjust the relative position of the wire temperature measurement sensor and the wire in the open state by using the relative rotation of the installation structure, so that the first clamp 18 and the second clamp 19 of the wire temperature measurement sensor can normally hold the wire after being separated from the limiting of the installation structure.

[0047] Step 4) After adjusting the relative position of the wire temperature measuring sensor and the wire, continue to lift the mounting structure so that the upper end of the wire temperature measuring sensor abuts the vertical lower end surface of the wire;

[0048] Step 5) Continue to apply the lifting force with the vertical lower end of the mounting structure, so that the wire compresses the cavity at the top of the mounting structure against the wire temperature measuring sensor, the wire temperature measuring sensor descends in the cavity at the top of the mounting structure, providing deformation space for the wire temperature measuring sensor to change from the open state to the tight state at the top of the mounting structure, continue to lift, the deformation space increases, until the wire temperature measuring sensor is completely separated from the limiting installation at the top of the mounting structure, the first clamp 18 and the second clamp 19 of the wire temperature measuring sensor quickly hold the wire, at this time the wire temperature measuring sensor and the mounting structure are separated, and the wire temperature measuring sensor performs contact temperature measurement on the wire. The torsion spring in the technical solution is specifically selected according to the description of Figure 3 . The selection is the prior art of the torsion spring. The torsion spring has the same structure in the first clamp 18 and in the second clamp 19.

[0049] The open limiting and fixing of the first clamp 18 and the second clamp 19 at the top of the mounting structure provides a prerequisite for the installation of the wire temperature measuring sensor on the wire, that is, the first clamp 18 and the second clamp 19 of the wire temperature measuring sensor are in an open state during installation, and in a completely tight state during temperature detection. The installation process is the deformation process of the first clamp 18 and the second clamp 19 from the open state to the tight state. With the relative rotation of the mounting structure, the length extension direction formed by the opening of the first clamp 18 and the second clamp 19 is as close to perpendicular to the length extension direction of the wire as possible, that is, the relative position of the first clamp 18 and the second clamp 19 and the wire is adjusted, and the cavity at the top of the mounting structure provides deformation space for the first clamp 18 and the second clamp 19. When the deformation space is sufficient for the first clamp 18 and the second clamp 19 to be relatively tightened and completely separated from the limiting installation at the top of the mounting structure, the first clamp 18 and the second clamp 19 quickly adhere to and hold the wire.

[0050] Refer to Figure 2 , in the step 1, the first clamp 18 and the second clamp 19 on the wire temperature measuring sensor are opened under the action of an external force and are limitingly installed in two oppositely arranged limiting grooves 14 at the vertical top of the mounting structure, wherein one limiting groove 14 limitingly installs one end of the first clamp 18, and the other limiting groove 14 limitingly installs one end of the second clamp 19, thereby completing the open state of the wire temperature measuring sensor in the limiting installation.

[0051] Refer to Figure 4In the step 1, the first clamp 18 or the second clamp 19 adopts a multi-section connecting rod in sequence connection form to increase the close-fitting degree of the first clamp 18 or the second clamp 19 to the wire, the adjacent two connecting rods of the first clamp 18 or the second clamp 19 adopt a rotary connection mode, and a torsional spring is added at each rotary connection, in the open state, under the action of an external force, the torsional spring is stretched, the connecting rods of the first clamp 18 are stretched along the length direction of the first clamp 18, and the connecting rods of the second clamp 19 are stretched along the length direction of the second clamp 19, when the open state is transited to the close-fitting state, the limiting action of the vertical top end of the mounting structure is gradually eliminated, the torsional spring is reset, under the resetting force of the torsional spring, the connecting rods of the first clamp 18 are relatively rotated, the connecting rods of the second clamp 19 are also relatively rotated, the first clamp 18 holds towards the second clamp 19, the second clamp 19 holds towards the first clamp 18, and finally the first clamp 18 and the second clamp 19 form a close-fitting on the outer side wall of the wire.

[0052] Referring to Figure 4 and Figure 5 , the first clamp 18 and the second clamp 19 are oppositely arranged and connected with one end of the temperature sensor body 16 through the mounting base 17, the first clamp 18 and the second clamp 19 are arranged on the end of the mounting base 17 away from the temperature sensor body 16, the temperature sensor body 16 is used for detecting the temperature of the wire, and the close-fitting of the first clamp 18 and the second clamp 19 to the wire fixes the temperature sensor body 16 on the wire to directly contact the wire for temperature detection.

[0053] Referring to Figure 4 , the mounting base 17 limits the rotary positions of the first clamp 18 and the second clamp 19 through two mounting slots 26, respectively, the first clamp 18 and the second clamp 19 are respectively provided with limiting slots for limiting the stretching of the torsional spring and limiting the rotary positions of the adjacent two connecting rods of the first clamp 18 or the second clamp 19, when the torsional spring is stretched and the adjacent two connecting rods of the first clamp 18 or the second clamp 19 are stretched to the open state, when the torsional spring is reset and the adjacent two connecting rods of the first clamp 18 or the second clamp 19 are close-fitted to the outer side wall of the wire, the close-fitting state is reached.

[0054] In the step 2, the wire temperature sensor is installed without cutting off the power supply of the wire, the connecting piece 2 with the universal connector 1 at the vertical bottom end of the mounting structure is made of insulating material, so as to cut off the risk of electrification of the wire temperature sensor after contacting the wire in the subsequent step.

[0055] Referring to Figure 1In the step 3, the relative rotation of the installation structure itself refers to that the mounting seat 3 connected by the connecting piece 2 is provided with a circular hole, the connecting piece 2 is provided with a connecting cylinder 5 at the end extending into the circular hole, the connecting cylinder 5 is relatively rotated in the circular hole, and the wire temperature sensor is below the wire and is limited by the wire, thereby completing the rotation of the connecting piece 2 and adjusting the relative position of the first clamp 18, the second clamp 19 and the wire length direction of the wire temperature sensor.

[0056] Referring to Figure 1 and Figure 5 In the step 5, in order to meet the wire temperature sensor in the open state, it can be stably limited and installed, the spring 12 is further arranged in the cavity, the baffle 11 is further arranged between the spring 12 and the wire temperature sensor, and the snap ring 13 is further arranged at the end of the cavity close to the wire temperature sensor. In the open state, the end of the wire temperature sensor away from the first clamp 18 extends into the cavity at the top of the installation structure, the baffle 11 is pushed down, the spring 12 is compressed, and when the lifting force is continuously applied, the wire temperature sensor continuously pushes down the baffle 11 in the cavity and compresses the spring 12. At this time, the first clamp 18 or the second clamp 19 starts to deform under the action of the spring reset, and as the wire temperature sensor goes down more and more, that is, the temperature sensor body 16 on the wire temperature sensor is farther and farther away from the vertical top of the installation structure, the deformation space of the first clamp 18 or the second clamp 19 is also larger and larger. When the first clamp 18 or the second clamp 19 holds the wire more and more tightly, it finally separates from the vertical top of the installation structure, and the first clamp 18 or the second clamp 19 holds the outer side wall of the wire.

[0057] In order to facilitate those skilled in the art to better understand the implementation of the installation detection method in the present technology, the specific structure of the installation structure and the wire temperature sensor is further described and explained.

[0058] Referring to Figure 1The mounting structure comprises a universal joint 1, a connecting piece 2, a mounting seat 3 and a limiting mounting rack 4. One end of the connecting piece 2 is connected with the universal joint 1, the other end of the connecting piece 2 is rotationally connected with one end of the mounting seat 3, the other end of the mounting seat 3 is detachably connected with the limiting mounting rack 4, and one end of the limiting mounting rack 4 away from the mounting seat 3 is used for limiting installation of the wire temperature sensor, that is, the limiting mounting rack 4 limits installation of the wire temperature sensor through two oppositely arranged limiting clamping grooves 14 of the limiting mounting rack 4. The limiting mounting rack 4 specifically comprises a cylindrical mounting seat 10, the limiting clamping grooves 14, a baffle 11 and a spring 12. The cylindrical mounting seat 10 is internally provided with a cavity penetrating through two ends, the baffle 11 and the spring 12 are installed in the cavity, one end of the spring 12 abuts against one end of the mounting seat 3, the other end of the spring 12 abuts against the baffle 11, and a clasp 13 is additionally arranged on the edge of the cavity near the wire temperature sensor, and the clasp 13 is used for limiting the baffle 11 in the cavity. The limiting clamping grooves 14 are connected on one end of the cylindrical mounting seat 10 away from the mounting seat 3. The “cavity” here is the cavity for being located at the top of the mounting structure as described in step 5. The connecting piece 2 and the universal joint 1 are made of insulating material. A circular hole is arranged on one end of the mounting seat 3 near the connecting piece 2, a connecting cylinder 5 at one end of the connecting piece 2 extends into the circular hole, the diameter of the connecting cylinder 5 is smaller than the diameter of the circular hole, in order to more stably realize relative rotation of the mounting structure itself and not to be easily detached, a bolt hole is arranged on the side wall of the mounting seat 3, a ring-shaped rotation limiting groove 7 is arranged on the connecting cylinder 5 at a position corresponding to the bolt hole, an adjusting screw 8 is inserted into the rotation limiting groove 7 through the bolt hole of the mounting seat 3, in order to further realize quick limiting installation, a limiting circular table 9 is extended from one end of the connecting cylinder 5 away from the mounting seat 3, the limiting circular table 9 limits the depth of the connecting cylinder 5 inserted into the circular hole and limits the rotation limiting groove 7 to be just aligned with the bolt hole, also realizes effective sealing of the gap between the connecting cylinder 5 and the circular hole, avoids obstacles from falling, and thus effectively guarantees the flexibility of relative rotation of the mounting structure itself in step 3. The cooperation of the rotation limiting groove 7 and the adjusting screw 8 also improves the flexibility of relative rotation of the mounting structure itself to a certain extent. In order to further increase the smoothness of disengagement of the first clamp 18 and the second clamp 19, the end of the limiting clamping groove 14 is arranged as a circular arc end 15. One end of the mounting seat 3 is detachably connected with one end of the cylindrical mounting seat 10 through a fixing screw 6. Thus, the baffle 11 and the spring 12 in the cavity of the cylindrical mounting seat 10 are quickly installed and are convenient to maintain.

[0059] Referring to Figure 4The wire temperature measuring sensor comprises a temperature measuring sensor body 16, a mounting base 17, a first clamp 18 and a second clamp 19, the temperature measuring sensor body 16 is fixedly connected to one end of the mounting base 17, and the first clamp 18 and the second clamp 19 are rotatably connected to one end of the mounting base 17 respectively. The first clamp 18 or the second clamp 19 in the foregoing technical solution adopts a multi-section connecting rod, a torsion spring and a rotary connection, and the rotary connection is specifically understood as follows: when the first clamp 18 adopts a three-section connecting rod, the first clamp 18 can comprise a first rotary plate 20, a first connecting plate 21, a first extension plate 22 and a first torsion spring 23, the first rotary plate 20 is rotatably connected to the mounting base 17 at one end, rotatably connected to the first connecting plate 21 and rotatably connected to the first extension plate 22 through a pin shaft 24, and a first torsion spring 23 is arranged at each rotary connection position, in order to enable the first torsion spring 23 to provide each rotary part with a relative holding force in rotation, i.e. the reset of the first torsion spring 23, a mounting slot 26 is additionally arranged at the connection position between the mounting base 17 and the first clamp 18, a first limiting slot 25 is additionally arranged at the length of the first connecting plate 21, the first torsion spring 23 is embedded in the mounting slot 26, and the other first torsion springs 23 are respectively embedded in the length of the first limiting slot 25. The mounting slot 26 or the first limiting slot 25 provides deformation limiting for the first torsion spring 23.
