Description

Technical Field

[0001] The present application relates to the technical field of wire temperature measurement installation, and in particular to an installation structure of a wire temperature measurement sensor. Background Art

[0002] When the conductor and hardware are running at high temperature, they will slowly anneal and age, causing their strength loss. The strength loss increases with the increase of the clamp temperature and time. Intermittent heating has a cumulative effect on the strength loss. Due to poor wire connection and excessive temperature of the connecting hardware, wire breakage occurs. Therefore, temperature monitoring of the conductor and hardware is particularly important. When installing traditional wire temperature sensors, the installation location is relatively limited due to structural problems. It can only be installed on the tension clamp drain plate. It cannot be installed on other easily heated monitoring points such as the conductor. It can no longer meet the needs of transmission line operation and maintenance monitoring. The installation process is complicated. At the same time, the original bolts of the tension clamp drain plate need to be removed after power outage and then tightened. It is easy to cause mechanical failures such as loose connection and even destructive consequences to the hardware.

[0003] With the continuous development of industry technology, there are also many patent technologies that are intended to solve the industry problems of traditional power-off installation and detection. For example, the Chinese patent with patent announcement number CN209525015U discloses a wire clamp temperature rise monitoring device for high-voltage live installation, which further discloses an installation tool, the installation tool includes a mounting frame, a fixing part matching the temperature probe, and a fixing groove matching the movable pressure plate, the fixing groove is connected to the bottom of the mounting frame, and a universal connector is provided on the top of the mounting frame. The installation tool is used in conjunction with the corresponding wire clamp temperature rise monitoring device to fix the wire clamp temperature rise monitoring device on the conductor or hardware without power failure. However, the installation tool can only be used for a specific wire clamp temperature rise monitoring device, that is, the specific wire clamp temperature rise monitoring device disclosed in the patent. In addition, there are some technical problems in the actual use of this patented technical solution. For example, once the specific wire clamp temperature rise monitoring device is subjected to accidental shaking or vibration caused by severe wind and snow weather, the movable pressure plate is easy to cause large friction damage with the wire clamp, causing it to fall off. At the same time, the shape of the wire clamp is limited to a rectangular structure design. If it is fixed to a cylindrical wire clamp with a circular cross-section, the contact point between the movable pressure plate and the wire clamp of this shape is smaller, causing the sensor to fall off easily. Therefore, when there are certain technical defects in the specific wire clamp temperature rise monitoring device, it is difficult for the matching installation tool to actually solve the technical installation problems in the industry.

[0004] With respect to the above-mentioned related technologies, new improvements need to be proposed for uninterruptible power installation. Utility Model Content

[0005] In order to solve the above problems, the present application provides an installation structure for a wire temperature sensor.

[0006] The present application provides an installation structure of a wire temperature sensor, which adopts the following technical solution:

[0007] A mounting structure for a wire temperature sensor comprises a universal connector, a connector, a mounting seat and a limit mounting frame, wherein one end of the connector is connected to the universal connector, the other end of the connector is rotatably connected to one end of the mounting seat, the other end of the mounting seat is detachably connected to the limit mounting frame, and the limit mounting frame is used to limit the wire temperature sensor at one end away from the mounting seat.

[0008] By adopting the above technical solution, the wire temperature sensor can be limited on the limit mounting frame. By rotating the connecting piece and the mounting seat, the orientation of the wire temperature sensor relative to the wire or the hardware can be adjusted. The mounting seat and the limit mounting frame are detachably connected, and the internal structure of the limit mounting frame can be conveniently and quickly installed. The connecting piece provides a connection between the universal connector and the mounting seat, and also provides support for the height required for the installation of the wire temperature sensor.

[0009] Optionally, a circular hole with a hollow interior is opened at one end of the mounting seat, and a connecting cylinder is provided at one end of the connecting piece, and the connecting cylinder extends into the circular hole. When the universal connector needs to rotate relative to the limiting mounting frame, the connecting cylinder rotates in the circular hole.

[0010] By adopting the above technical solution, the relative rotation of one end of the connecting piece to one end of the mounting seat can be achieved, thereby adjusting the relative position of the mounting seat and the connecting piece, and further adjusting the relative position of the limit mounting frame and the connecting piece, and finally achieving the relative position of the wire temperature sensor and the universal connector at the bottom end of the connecting piece.

[0011] Optionally, a rotation limiting groove is provided on the connecting cylinder, and a limiting hole is provided on the mounting seat. When the connecting cylinder extends into the circular hole, the limiting hole and the rotation limiting groove are fixed by adjusting screws.

[0012] By adopting the above technical solution, the coordinated use of the adjusting screw, the limiting hole and the rotation limiting groove can realize the rotation of the connecting cylinder on the connecting piece in the circular hole on the mounting seat without falling off, and it is also convenient for disassembly, maintenance and repair between components.

[0013] Optionally, a limiting truncated cone is additionally provided on the connecting member, and one end surface of the limiting truncated cone abuts against one end surface of the mounting seat.

[0014] By adopting the above technical solution, the limiting cone has the following three main functions: first, it allows a shape transition between the connecting piece and the connecting cylinder; second, it can seal the circular hole on the mounting seat; third, it limits the depth of the connecting cylinder inserted into the circular hole of the mounting seat, that is, it limits the precise insertion of the adjusting screw into the rotation limit groove.

[0015] Optionally, the limit mounting frame includes a columnar mounting seat, a limit block, a baffle and a spring. The columnar mounting seat is provided with a cavity with two ends passing through it. The baffle and spring are installed in the cavity. One end of the spring abuts against the mounting seat, and the other end of the spring abuts against the baffle. The limit block is connected to the end of the columnar mounting seat away from the mounting seat.

[0016] By adopting the above technical solution, the cavity provides an accommodating and installing space for the wire temperature sensor, that is, the temperature sensor is inserted into the cavity from one end of the baffle, the baffle moves downward, the spring is compressed, and the other end of the temperature sensor is opened and stuck on the limit block. When the temperature sensor contacts the wire or the hardware, the operator continues to apply an upward force, and the other end of the temperature sensor abuts against the wire or the hardware. The end of the temperature sensor inserted into the cavity continues to move in the cavity toward the mounting seat, the spring is further compressed, and the end of the temperature sensor away from the cavity is detached from the limit block. The wire or the hardware is clamped by the clamp on the temperature sensor itself to achieve the final installation.

[0017] Optionally, a clamping ring extends from one end of the cavity close to the baffle, and the clamping ring limits the installation of the baffle and limits the end point of the baffle's translation in the cavity along one end of the limiting block.

[0018] By adopting the above technical solution, the design of the clamp ring ensures that the spring and the baffle are installed in the cavity with limited position, and also ensures the translation height of the baffle when the spring is retracted and reset. The simple design of the cavity with a clamp ring has a simple structure and high practicality, and can also well meet the installation of the temperature sensor and the reciprocating motion in the cavity in the technical implementation.

[0019] Optionally, there are two limit blocks, which are arranged opposite to each other, and a limit slot is provided at one end of the limit block away from the columnar mounting seat.

[0020] By adopting the above technical solution, the function of the limit slot is to provide a limit for the installation state of the temperature measuring sensor when the temperature measuring sensor is opened and enters the installation state, so that it can remain in the installation state.

[0021] Optionally, an arc end is provided at one end of the limit slot.

[0022] By adopting the above technical solution, the arc end is designed to facilitate the temperature sensor to be able to detach from the limit slot more smoothly and quickly when it transitions from the installation state to the state of holding the wire or the hardware.

[0023] Optionally, the connecting piece is made of insulating material.

[0024] By adopting the above technical solution, the live installation of the temperature sensor brings convenience and cost savings for uninterrupted power supply, but also brings high risk of electric shock to the installers. Therefore, the connector close to the installer is set to insulating material to ensure the safety of the installer.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By adopting the above technical solution, a new technology can be provided for live installation.

[0027] 2. By adopting the above technical solution, the wire temperature sensor can be limited on the limit mounting frame. By rotating the connecting piece and the mounting seat, the orientation of the wire temperature sensor relative to the wire or the hardware can be adjusted. The mounting seat and the limit mounting frame are detachably connected, which can conveniently and quickly realize the structural installation inside the limit mounting frame. The connecting piece provides a connection between the universal connector and the mounting seat, and also provides support for the height required for the installation of the wire temperature sensor.

[0028] 3. By adopting the above technical solution, the connecting cylinder rotates freely in the round hole, which can well adjust the position of the wire temperature sensor relative to the wire or hardware when it is installed, so that the wire temperature sensor can correctly hold the wire or hardware when it is in the holding state.

[0029] 4. By adopting the above technical solution, the annular rotation limit groove opened on the connecting cylinder cooperates with the adjusting screw, so that the rotation of the connecting cylinder in the circular hole can be more flexible, and the end of the connecting cylinder will not abut against the inside of the circular hole, thereby restricting the rotation; by fixing one end of the adjusting screw in the limit hole of the mounting seat, the connecting cylinder can rotate in the circular hole without falling off.

[0030] 5. By adopting the above technical solution, the limiting cone limits the depth of the connecting cylinder inserted into the circular hole, maintains flexible and free rotation, provides positioning for the adjusting screw to be inserted into the rotation limiting groove more quickly, and can also play a role in sealing the annular gap between the connecting cylinder and the circular hole.

[0031] 6. By adopting the above technical solution, the columnar mounting seat, baffle and spring of the limit mounting frame provide installation space for the wire temperature sensor, and can lock the installation state of the wire temperature sensor under the action of the limit block. When the wire temperature sensor continues to compress the baffle and the spring in the cavity of the columnar mounting seat under the action of external force, the wire temperature sensor detaches from the limit block and enters a clamping state, and then the spring resets, pushing the baffle upward in the cavity until it is limited by the clamping ring.

DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0039] An embodiment of the present application discloses a mounting structure for a wire temperature sensor.

[0040] Reference Figure 1 A mounting structure of a wire temperature sensor comprises a universal connector 1, a connector 2, a mounting seat 3 and a limit mounting bracket 4, one end of the connector 2 is connected to the universal connector 1, the other end of the connector 2 is rotatably connected to one end of the mounting seat 3, the other end of the mounting seat 3 is detachably connected to the limit mounting bracket 4, and the limit mounting bracket 4 is used to limit the wire temperature sensor at one end away from the mounting seat 3.

[0041] The implementation principle of the installation structure of a wire temperature sensor in an embodiment of the present application is: one end of the wire contact temperature sensor is unfolded and limitedly installed on the upper end of the limit installation frame 4 to achieve the installation state of the wire contact temperature sensor, that is, the open state, and the universal connector 1 is used for convenient and quick connection between the installation structure and the external structure.

[0042] A circular hole with a hollow interior is provided at one end of the mounting seat 3, and a connecting cylinder 5 is provided at one end of the connector 2. The connecting cylinder 5 extends into the circular hole. When the universal connector 1 needs to rotate relative to the position-limiting mounting bracket 4, the connecting cylinder 5 rotates in the circular hole. The diameter of the connecting cylinder 5 is smaller than the diameter of the circular hole, and the diameter difference between the two is about 2-8 mm, which has a relatively good effect. Through the relative rotation of the connecting cylinder 5 in the circular hole, the relative position of the connector 2 and the wire contact temperature sensor on the mounting seat 3 can be flexibly and quickly adjusted, that is, the relative position of the wire contact temperature sensor and the wire is realized.

[0043] A rotation limiting groove 7 is provided on the connecting cylinder 5, and a limiting hole is provided on the mounting seat 3. When the connecting cylinder 5 is inserted into the circular hole, the limiting hole and the rotation limiting groove 7 are fixed by the adjusting screw 8. The rotation limiting groove 7 is provided in an annular shape on the outer wall of the connecting cylinder 5, and the adjusting screw 8 is inserted into the rotation limiting groove 7 through the limiting hole of the mounting seat 3, so that the connecting cylinder 5 and the mounting seat 3 are relatively fixedly installed and are not easy to fall off from the circular hole. In addition, an appropriate gap is left between the end face of the insertion end of the connecting cylinder 5 and the end face of the bottom of the depth of the circular hole to avoid the end face of the insertion end of the connecting cylinder 5 and the end face of the bottom of the depth of the circular hole, so as to ensure the flexibility of relative rotation, that is, to achieve more flexible adjustment of the relative position of the wire contact temperature sensor and the wire.

[0044] A limiting truncated cone 9 is added to the connecting member 2, and one end face of the limiting truncated cone 9 abuts against one end face of the mounting seat 3. The limiting truncated cone 9 can close the gap between the connecting cylinder 5 and the circular hole to a certain extent, ensuring the cleanliness of the rotating cavity of the circular hole, that is, ensuring that the rotation flexibility is not hindered by the entry of foreign objects. The limiting truncated cone 9 can also locate the depth of the connecting cylinder 5 extending into the circular hole, realize the rapid position docking of the limiting hole and the rotating limiting groove 7, and improve the installation efficiency of the adjusting screw 8.

[0045] The limit mounting frame 4 includes a columnar mounting seat 10, a limit block, a baffle 11 and a spring 12. The columnar mounting seat 10 is provided with a cavity with two ends passing through it. The baffle 11 and the spring 12 are installed in the cavity. One end of the spring 12 abuts against the mounting seat 3, and the other end of the spring 12 abuts against the baffle 11. The limit block is connected to the end of the columnar mounting seat 10 away from the mounting seat 3. One end of the wire contact temperature sensor is inserted into the cavity, and the baffle 11 is pushed toward one end of the mounting seat 3. The spring 12 is compressed until the clamping structure of the wire contact temperature sensor is fully opened and limitedly installed between two relatively set limit blocks, so as to realize the installation state of the wire contact temperature sensor, that is, the open state. One end of the columnar mounting seat 10 is fixed to the mounting seat 3 by a fixing screw 6.

[0046] A clamping ring 13 extends from one end of the cavity near the baffle 11, and the clamping ring 13 limits the installation of the baffle 11 and limits the end point of the translation of the baffle 11 along one end of the limit block in the cavity. In the installed state, the installation structure continues to rise until the upper end of the wire contact temperature sensor abuts against the wire, and then rises again. Under the resistance of the wire, the wire contact temperature sensor continues to push down the baffle 11 and continues to compress the spring 12 to provide space for the deformation of the clamping structure of the wire contact temperature sensor. When the space is sufficient, the clamping structure starts to clamp and deform, and detaches from between the two relatively set limit blocks. After that, the clamping structure enters the process of quickly clamping the wire, and finally completely clamps the wire.

[0047] There are two limit blocks, which are arranged opposite to each other, and a limit slot 14 is arranged at one end of the limit block away from the columnar mounting seat 10. The clamping structure of the wire contact temperature sensor is specifically clamped in the two limit slots 14 when it is opened.

[0048] One end of the position-limiting slot 14 is provided with an arc end 15. The arc end 15 is designed to allow the clamping structure of the wire contact temperature sensor to be better and more smoothly separated from the position-limiting slot 14 during the deformation process.

[0049] The connector 2 is made of insulating material. The design of the insulating material is also for greater safety under non-power-off installation.

[0050] In order to enable those skilled in the art to better understand how the installation mechanism in the present technology installs the wire contact type temperature measurement sensor on the wire, the structural composition of the wire contact type temperature measurement sensor is explained here.

[0051] The wire contact temperature sensor includes a temperature sensor body 16 and a clamping structure, one end of the temperature sensor body 16 is connected to one end of the clamping structure, the temperature sensor body 16 is directly clamped on the wire through the clamping structure, the clamping structure includes a mounting base 17, a first clamp 18 and a second clamp 19, the temperature sensor body 16 is mounted on the mounting base 17, and the first clamp 18 and the second clamp 19 are symmetrically mounted on both sides of the mounting base 17. The first clamp 18 and the second clamp 19 have the same structural principle, and both adopt a technical solution of torsion spring reset, rotational connection between components, and a limit notch to provide a torsion spring reset force and limit the rotation angle. According to different requirements for the wire clamping stability, the structures of the first clamp 18 and the second clamp 19 can be set to be the same or different. For example, the first clamp 18 is provided with a first rotating plate 20, a first connecting plate 21, a first extension plate 22 and a first torsion spring 23. One end of the first rotating plate 20 is connected to the mounting base 17, the first rotating plate 20 is connected to the first connecting plate 21, and the first connecting plate 21 is connected to the first extension plate 22 by means of a pin 24. A first torsion spring 23 is added at each rotating connection. In order for the first torsion spring 23 to provide each rotating component with a relative rotational force, that is, the first torsion spring 23 is reset, a mounting notch 26 is added at the connection between the mounting base 17 and the first clamp 18, and a first limiting notch 25 is added on the length of the first connecting plate 21. The first torsion spring 23 is embedded in the mounting notch 26, and the other first torsion springs 23 are respectively embedded at both ends of the length of the first limiting notch 25. The first torsion spring 23 is provided with deformation and limiting through the mounting notch 26 or the first limiting notch 25. The first clamp 18 realizes the clamping relative to the wire through the torsion of the first torsion spring 23.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
