Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, and in particular to a sensor installation structure based on ultrasonic detection of metal particles in GIS. Background Technology

[0002] As is well known, in the sensor installation structure based on ultrasonic detection of GIS metal particles, the accelerometer is usually arranged on the outer surface below the housing of the GIS circuit breaker under test, the external impact vibration device is also located on the outer surface below the housing, and the four ultrasonic sensors are evenly distributed on the outer surface below the housing of the gas chamber under test. Each device and sensor is connected to the ultrasonic detection device through a coaxial signal transmission line, thus forming the sensor installation layout for detecting metal particles.

[0003] Existing GIS UHF sensors are all connected using flanges and bolts during installation. This connection method is not only slow to disassemble and repair, but also easily damages the flange thread holes or bolts, resulting in insecure installation. In addition, it requires tightening back and forth during installation, which is quite complicated. An existing patent (publication number: CN214174452U) discloses an installation device for a GIS UHF sensor, including a GIS UHF sensor body and a mounting base. One end of the GIS UHF sensor body is fixedly connected to a mounting plate. A mounting flange is provided on the outer ring of the mounting plate. The mounting flange and the mounting base are connected by bolts. A sealing device is provided between the mounting plate and the mounting base. Several limiting blocks are movably inserted into the side wall of the mounting plate. One end of each limiting block is connected to the interior of the mounting plate by a first spring. The bottom of the limiting block at the outer end of the mounting plate is a sloping surface. Several limiting grooves matching the limiting blocks are provided on the inner wall of the mounting flange. This utility model allows for maintenance and replacement of the GIS UHF sensor body by simply fixing the mounting flange once, eliminating the need for subsequent disassembly. Only the mounting plate needs to be removed. This simplifies the operation and increases the service life of the mounting flange and the mounting base.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, when installed inside the GIS circuit breaker housing, the lack of an installation structure adapted to the housing's shape prevents the sensor from being installed in a way that conforms to the housing's shape, thus reducing the sensor's installation flexibility.

[0005] To address this, a sensor mounting structure based on ultrasonic detection of metal particles using GIS is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a sensor mounting structure based on ultrasonic detection of GIS metal particles, which can solve the problem that the existing lack of mounting structures that adapt to the shape of the housing makes it impossible to mount the sensor according to the shape of the housing, thus reducing the flexibility of the sensor during installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sensor mounting structure for ultrasonic detection of GIS metal particles, comprising an adjustment mechanism, an assembly mechanism, and a sensor body. The assembly mechanism is located on top of the adjustment mechanism, and the sensor body is located on top of the assembly mechanism. The adjustment mechanism includes a positioning frame, an adjustment handle, adjustment screws, and a positioning plate. The adjustment handle is rotatably connected to the inner side of the positioning frame, the two adjustment screws are threadedly connected to both sides of the adjustment handle, and the positioning plate is fixedly connected to both sides of the adjustment screws.

[0008] Preferably, the assembly mechanism includes a positioning component and an installation component. The positioning component is located at the bottom of the positioning plate, and the installation component is located inside the positioning component. The top of the installation component is fixedly connected to the bottom of the sensor body.

[0009] Preferably, the positioning assembly includes a positioning base, a magnetic ring, and a limiting sleeve. The four positioning bases are respectively fixedly connected to the bottom of the positioning plate on the side away from the positioning frame. The magnetic ring is fixedly connected to the top of the positioning base, and the limiting sleeve is fixedly connected to the top of the magnetic ring.

[0010] Preferably, the mounting assembly includes a cross rod, a magnetic hook plate, a connecting top rod, and a reset ring. The cross rod is inserted into the inner side of the limiting sleeve. The magnetic hook plate is rotatably connected to the top of the inner side of the cross rod, and the surface of the magnetic hook plate contacts the inner side of the magnetic ring. The connecting top rod is fixedly connected to the top of the cross rod, and the reset ring is slidably connected to the top of the surface of the cross rod.

[0011] Preferably, the surface of the adjusting handle is covered with a protective sleeve, and the surface of the protective sleeve is provided with anti-slip texture.

[0012] Preferably, a reinforcing sleeve is fixedly connected to the side of the adjusting screw away from the adjusting handle, and the side of the reinforcing sleeve away from the adjusting handle is fixedly connected to the positioning plate.

[0013] Preferably, a positioning hole plate is fixedly connected to the inner side of the positioning base, and a connection hole is provided on the top of the positioning hole plate.

[0014] Preferably, a reset magnet is fixedly connected to the top of the surface of the cross bar, the surface of the reset magnet is in contact with the inner side of the reset ring, the bottom of the surface of the magnet hook plate is set as the positive pole, the inner side of the reset ring is set as the positive pole, and the surface of the reset magnet is set as the negative pole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting an adjustment mechanism, allows the positioning frame to be used in conjunction with the adjustment handle, adjustment screw, and positioning plate. The positioning frame provides support and limits for the adjustment handle. When the positioning frame is located on the outer surface below the GIS circuit breaker housing, the adjustment handle moves the adjustment screw thread when it rotates. Since the adjustment screw has two threads with different directions, it can rotate axially in the same direction as the adjustment handle, achieving the effect of bringing the two adjustment screws closer to each other and further away from each other. This changes the distance between the positioning plates, thereby adjusting the orientation of the positioning base connected to them. This allows the positioning base to adapt to the shape of the outer surface below the GIS circuit breaker housing, allowing the sensor body to move to the required orientation. 2. This application, by setting up an assembly mechanism, allows the positioning component to cooperate with the installation component. The positioning base provides support and limitation for the magnetic ring and the limiting sleeve, allowing the magnetic ring and positioning base to form a structure that limits the magnetic hook plate. Simultaneously, it limits the insertion of the cross rod. The cross rod, together with the magnetic hook plate and connecting top rod, forms a structure that limits the sensor body. When the magnetic hook plate is inserted into the limiting sleeve along with the cross rod, the magnetic force of the magnetic ring attracts the magnetic hook plate to its surface, allowing the magnetic hook plate to contact the bottom of the limiting sleeve using its hook-like structure, thus limiting the cross rod. When the reset ring moves downwards, the magnetic repulsion pushes the magnetic hook plate towards the center of the cross rod, moving it away from the magnetic ring and limiting sleeve, thus releasing the connection between the magnetic hook plate and the limiting sleeve. Ultimately, this facilitates the installation of the sensor body, along with the connecting top rod, cross rod, and magnetic hook plate, onto the magnetic ring and limiting sleeve. The sensor body is an existing sensor device for ultrasonic detection of metal particles in GIS. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A sensor mounting structure for ultrasonic detection of GIS metal particles includes an adjustment mechanism 1, an assembly mechanism 2, and a sensor body 3. The assembly mechanism 2 is located on top of the adjustment mechanism 1, and the sensor body 3 is located on top of the assembly mechanism 2. The adjustment mechanism 1 includes a positioning frame 11, an adjustment handle 12, adjustment screws 13, and a positioning plate 14. The adjustment handle 12 is rotatably connected to the inner side of the positioning frame 11, and two adjustment screws 13 are threaded to both sides of the adjustment handle 12. The positioning plate 14 is fixedly connected to both sides of the adjustment screws 13.

[0020] In this embodiment: By setting the adjustment mechanism 1, the positioning frame 11 can be used in conjunction with the adjustment handle 12, the adjustment screw 13, and the positioning plate 14. The positioning frame 11 provides support and limit for the adjustment handle 12. When the positioning frame 11 is set on the outer surface below the GIS circuit breaker housing, the adjustment handle 12 can move the adjustment screw 13 threadedly when it rotates. Since the adjustment screw 13 has two threads with different directions, it can rotate axially in the same direction as the adjustment handle 12, so as to achieve the effect of making the two adjustment screws 13 move closer and further away from each other. This can change the distance between the positioning plates 14, thereby adjusting the orientation of the positioning base 211 connected to it, so that the positioning base 211 adapts to the shape of the outer surface below the GIS circuit breaker housing, and the sensor body 3 moves to the required orientation accordingly.

[0021] Specifically, such as Figure 3As shown, the assembly mechanism 2 includes a positioning component 21 and an installation component 22. The positioning component 21 is located at the bottom of the positioning plate 14, and the installation component 22 is located inside the positioning component 21. The top of the installation component 22 is fixedly connected to the bottom of the sensor body 3.

[0022] Specifically, such as Figure 4 As shown, the positioning component 21 includes a positioning base 211, a magnetic ring 212, and a limiting sleeve 213. The four positioning bases 211 are respectively fixedly connected to the bottom of the positioning plate 14 on the side away from the positioning frame 11. The magnetic ring 212 is fixedly connected to the top of the positioning base 211, and the limiting sleeve 213 is fixedly connected to the top of the magnetic ring 212.

[0023] Specifically, such as Figure 5 As shown, the mounting assembly 22 includes a cross rod 221, a magnetic hook plate 222, a connecting top rod 223, and a reset ring 224. The cross rod 221 is inserted into the inner side of the limiting sleeve 213. The magnetic hook plate 222 is rotatably connected to the top of the inner side of the cross rod 221. The surface of the magnetic hook plate 222 contacts the inner side of the magnetic ring 212. The connecting top rod 223 is fixedly connected to the top of the cross rod 221. The reset ring 224 is slidably connected to the top of the surface of the cross rod 221.

[0024] In this embodiment: by setting the assembly mechanism 2, the positioning component 21 can cooperate with the installation component 22. The positioning base 211 provides support and limitation for the magnetic ring 212 and the limiting sleeve 213, allowing the magnetic ring 212 and the positioning base 211 to form a structure that limits the magnetic hook plate 222. At the same time, it can limit the insertion of the cross rod 221. The cross rod 221 can form a structure that limits the sensor body 3 with the magnetic hook plate 222 and the connecting top rod 223. When the cross rod 221 is inserted into the limiting sleeve 213, the magnetic hook plate 222 is attracted to its surface by the magnetic force of the magnetic ring 212, thereby allowing the magnetic hook plate 222 to be attracted to its surface. By utilizing its hook-like structure to contact the bottom of the limiting sleeve 213, the cross rod 221 is limited. When the reset ring 224 moves downward, the magnetic repulsive force can be used to push the magnetic hook plate 222 towards the center of the cross rod 221, thereby moving the magnetic hook plate 222 away from the magnetic ring 212 and the limiting sleeve 213, thus releasing the connection between the magnetic hook plate 222 and the limiting sleeve 213. Ultimately, this facilitates the installation of the sensor body 3, along with the connecting top rod 223, the cross rod 221, and the magnetic hook plate 222, onto the magnetic ring 212 and the limiting sleeve 213. The sensor body 3 is an existing sensor device for ultrasonic detection of metal particles in GIS.

[0025] Specifically, such as Figure 2 As shown, a protective sleeve 15 is fitted onto the surface of the adjusting handle 12, and the surface of the protective sleeve 15 is provided with anti-slip texture.

[0026] Specifically, such as Figure 2 As shown, a reinforcing sleeve 16 is fixedly connected to the side of the adjusting screw 13 away from the adjusting handle 12, and the side of the reinforcing sleeve 16 away from the adjusting handle 12 is fixedly connected to the positioning plate 14.

[0027] In this embodiment: by setting a protective sleeve 15 and a reinforcing sleeve 16, the protective sleeve 15 can cooperate with the adjusting handle 12. When the user holds the protective sleeve 15 with anti-slip texture, the anti-slip texture can increase the stability of the user holding the protective sleeve 15, thereby further increasing the stability of the user rotating the adjusting handle 12. The reinforcing sleeve 16 can cooperate with the adjusting screw 13. By reinforcing the connection between the adjusting screw 13 and the positioning plate 14, the connection between the adjusting screw 13 and the positioning plate 14 can be further reinforced, thereby increasing the stability of the adjusting screw 13 moving the positioning plate 14.

[0028] Specifically, such as Figure 4 As shown, a positioning hole plate 214 is fixedly connected to the inner side of the positioning base 211, and a connection hole is provided on the top of the positioning hole plate 214.

[0029] Specifically, such as Figure 5 As shown, a reset magnet 225 is fixedly connected to the top of the surface of the cross bar 221. The surface of the reset magnet 225 is in contact with the inner side of the reset ring 224. The bottom of the surface of the magnet hook plate 222 is set as the positive pole, the inner side of the reset ring 224 is set as the positive pole, and the surface of the reset magnet 225 is set as the negative pole.

[0030] In this embodiment: by setting a positioning hole plate 214 and a reset magnet 225, the positioning hole plate 214 allows the sensor body 3 to pass its own detection head and connected data cable through its connection hole, thereby further increasing the detection range of the outer surface below the GIS circuit breaker housing. The reset magnet 225 can cooperate with the reset ring 224. By setting the surface of the reset magnet 225 as the negative pole and the inner side of the reset ring 224 as the positive pole, when the inner side of the reset ring 224 contacts the surface of the reset magnet 225, the reset ring 224 can be temporarily limited by the principle of magnetic attraction between opposite poles. By setting the inner side of the reset ring 224 as the positive pole and the bottom of the surface of the magnet hook plate 222 as the positive pole, the magnet hook plate 222 is pushed towards the center of the cross rod 221 by the repulsive force when the reset ring 224 approaches the bottom of the surface of the magnet hook plate 222, thereby releasing the connection between the magnet hook plate 222 and the limiting sleeve 213.

[0031] Working principle: First, the positioning frame 11 is placed on the outer surface below the housing of the GIS circuit breaker to be tested. Then, by rotating the adjusting handle 12, the distance between the adjusting screws 13 is changed, so that the adjusting screws 13 drive the positioning plate 14 to adjust the distance between the positioning bases 211 until the positioning bases 211 move to the position to be tested. Then, the cross bar 221 with the sensor body 3 is inserted into the inside of the limiting sleeve 213 until the surface of the magnetic hook plate 222 approaches the magnetic ring 212 by magnetic force. When it is necessary to remove the sensor body 3, the reset ring 224 is pushed towards the limiting sleeve 213 until the reset ring 224 uses magnetic force to move the magnetic hook plate 222 away from the magnetic ring 212 and closer to the cross bar 221. Then, the cross bar 221 can be removed from the limiting sleeve 213.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
