Description

Technical Field

[0001] This utility model relates to the field of fiber optic sensor technology, and in particular to an edge mounting structure for a fiber optic sensor. Background Technology

[0002] According to Chinese Patent Publication No. CN219624782U, a fiber optic sensor with an edge protection structure includes a sensor body and an optical fiber connected to one side of the sensor body. The end of the optical fiber away from the sensor body is connected to an optical fiber head. Protective frames are provided at both ends of the sensor body, and four sets of corner arc-shaped protective plates for protecting the edges of the sensor body are connected between the two sets of protective frames. The inner walls of the corner arc-shaped protective plates are connected to the sensor body through several buffer rods. One end of the sensor body has a connector for optical fiber insertion, and a positioning component is connected to the end of the sensor body near the connector for protecting and fixing the end of the optical fiber near the optical fiber head. The protective frames and corner arc-shaped protective plates in this invention protect the edges of the sensor body, improving the sensor's protective performance during use. The positioning component protects and fixes the end of the optical fiber near the optical fiber head, facilitating the connection of the optical fiber to the sensor body.

[0003] The aforementioned comparative documents and existing technologies have the following technical problems: During the installation and use of existing fiber optic sensors, the center is often fixed or clamped. These methods have defects such as complex structure, poor repeatability and positioning accuracy, inconvenience of disassembly and assembly, and easy damage to fiber optic sensors, making it difficult to meet the needs of high precision, multiple disassembly and assembly, and rapid on-site maintenance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an edge mounting structure for fiber optic sensors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an edge mounting structure for an optical fiber sensor, comprising a protective housing, a transparent cover on the top of the protective housing, a bottom connecting seat on the bottom of the protective housing, a mounting base on the bottom of the connecting seat, and an optical fiber sensor disposed inside the protective housing.

[0006] Preferably, the protective housing has a connecting sleeve on one side, a connecting hole on the other side, and a hole-shaped slot on the top side.

[0007] Preferably, one side of the protective housing is provided with a light-emitting fiber optic line, and the other side of the protective housing is provided with a light-receiving fiber optic line. The light-emitting fiber optic line is connected to the fiber optic sensor through a connecting sleeve, and the light-receiving fiber optic line is connected to the fiber optic sensor through a connecting hole.

[0008] Preferably, the transparent cover has a pivot on the other side, and the transparent cover is connected to the protective shell through the pivot. The top of the protective shell has a side groove that fits with the transparent cover.

[0009] Preferably, the transparent cover has a locking post on one side, which cooperates with a hole-shaped slot on the top side of the protective shell, and a buckle groove on one side of the locking post.

[0010] Preferably, the bottom of the connector is provided with a V-groove, the top edge of the mounting base is provided with screw holes, and the connector and the mounting base are welded together.

[0011] Preferably, the bottom of the protective shell is provided with a clamping block, the shape of which is consistent with the V-groove at the bottom of the connecting seat, and the clamping block and the V-groove cooperate with each other. The top of the clamping block is connected to the protective shell by a welding rod. An eccentric wheel is provided inside the V-groove. An operating handle is provided on one side of the mounting base. The operating handle is connected to the eccentric wheel. A rotating shaft is provided inside the eccentric wheel.

[0012] Beneficial effects This invention employs a modular design. When the internal fiber optic sensor malfunctions, ages, or is damaged, maintenance personnel do not need to remove the mounting base fixed to the structure under test. They only need to remove the old protective shell or sensing module through the unlocking mechanism and replace it with a new or repaired module. This process is quick and simple, greatly shortening equipment downtime and maintenance cycle, and significantly reducing the complexity and overall cost of on-site maintenance.

[0013] This invention employs a V-groove and a locking block. When connection is required, first, move the operating handle to the unlocked position. At this point, the smallest radius of the eccentric wheel faces the V-groove. Align the V-shaped locking block at the bottom of the protective housing with the V-groove on the mounting base, and then smoothly slide the protective housing in. The inclined surface of the V-groove will automatically guide and correct the module's position, ensuring precise positioning on a horizontal plane. After the protective housing has slid to the predetermined position, move the operating handle towards the locking direction. As the handle rotates, the eccentric wheel rotates around its axis. Because its center of rotation is offset, the distance from its contour edge to the center of rotation gradually increases during rotation. The outer edge is designed to press precisely onto a specific plane of the protective housing's locking block. As the radius increases, the eccentric wheel generates a strong and continuously increasing downward or lateral force. This force presses the V-shaped locking block of the protective housing extremely tightly into the V-groove of the mounting base, eliminating all potential micro-gaps. When the handle is fully extended, self-locking is achieved to prevent loosening caused by vibration. At this point, the protective housing is firmly locked onto the base, achieving a rigid connection. By reversing the operating handle, the eccentric wheel rotates back to its initial position, releasing the pressure instantly, and the protective housing can easily slide off the base. This enables fast, repeatable, high-precision, and highly reliable modular installation. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-6This utility model provides an edge mounting structure for an optical fiber sensor, including a protective housing 1, a transparent cover 2 on the top of the protective housing 1, a connecting seat 3 at the bottom of the protective housing 1, a mounting base 4 at the bottom of the connecting seat 3, an optical fiber sensor 5 inside the protective housing 1, a connecting sleeve 101 on one side of the protective housing 1, a connecting hole 102 on the other side of the protective housing 1, a hole-shaped slot 103 on one side of the top of the protective housing 1, a light-emitting optical fiber 6 on one side of the protective housing 1, and a light-receiving optical fiber 7 on the other side of the protective housing 1. The light-emitting optical fiber 6 is connected to the optical fiber sensor 5 through the connecting sleeve 101, and the light-receiving optical fiber 7 is connected to the optical fiber sensor 5 through the connecting hole 102. The other side of the transparent cover 2 has... A rotating shaft connects the transparent cover 2 and the protective shell 1. The top of the protective shell 1 has a groove that fits snugly against the transparent cover 2. A locking post 201 is located on one side of the transparent cover 2, which engages with a slot 103 on the top side of the protective shell 1. A latching groove 202 is located on one side of the locking post 201, allowing the transparent cover 2 to be opened. A V-groove 301 is located at the bottom of the connecting seat 3. A screw hole 401 is located at the top edge of the mounting base 4. The connecting seat 3 and the mounting base 4 are welded together. A locking block 8 is located at the bottom of the protective shell 1. The shape of the locking block 8 matches the V-groove 301 at the bottom of the connecting seat 3, and the locking block 8 engages with the V-groove 301. The top of the locking block 8 is welded to the protective shell 1. The rods are connected, and the V-groove 301 contains an eccentric wheel 302. An operating handle is located on one side of the mounting base 4, and the operating handle is connected to the eccentric wheel 302. The eccentric wheel 302 contains a rotating shaft and utilizes the V-groove 301 and a locking block 8. When connection is required, first, move the operating handle to the unlocked position. At this time, the smallest radius of the eccentric wheel 302 faces the V-groove 301. Align the V-shaped locking block 8 at the bottom of the protective housing 1 with the V-groove 301 on the mounting base 4, and then smoothly slide the protective housing 1 in. The inclined surface of the V-groove 301 will automatically guide and correct the position of the module, ensuring precise positioning on the horizontal plane. After the protective housing 1 slides to the predetermined position, move the operating handle in the locking direction. As the handle rotates, the eccentric wheel 302... The eccentric wheel 302 rotates around its axis. Because its center of rotation is offset, the distance from its contour edge to the center of rotation gradually increases during rotation. The contour edge of the eccentric wheel 302 is designed to press precisely onto a specific plane of the locking block 8 of the protective housing 1. As the radius increases, the eccentric wheel 302 generates a strong and continuously increasing downward or lateral force. This force presses the V-shaped locking block 8 of the protective housing 1 extremely tightly into the V-groove 301 of the mounting base 4, eliminating all potential micro-gaps. When the handle is fully extended, self-locking is achieved to prevent loosening due to vibration. At this point, the protective housing 1 is firmly locked onto the base, achieving a rigid connection. Reversing the operation handle returns the eccentric wheel 302 to its initial position, instantly releasing the pressure.The protective shell 1 can easily slide off the base, enabling rapid, repeatable, high-precision, and highly reliable modular installation. Specific Implementation Example 2: Reference Figure 1 Utilizing the properties of smart materials, self-locking or adaptive clamping is achieved after installation. The active clamping driven by smart materials involves designing a clamp made of shape memory alloy. In the initial state, the clamp is loose, making it easy to install it on the edge of the structure and place the optical fiber. After installation, through simple heating, the shape memory alloy material undergoes a phase change, restoring its preset memory shape, thereby generating a precise, uniform, and powerful clamping force to firmly lock the sensor. No screws or tools are required; only placement and heating are needed. The clamping force is determined by the phase change characteristics of the material, is highly repeatable and very stable, and the integrated structure eliminates the problem of loose threads.

[0020] In summary: The modular design allows maintenance personnel to remove the mounting base 4 fixed to the structure under test when the internal fiber optic sensor 5 fails, ages, or is damaged. They only need to use the unlocking mechanism to remove the old protective shell 1 or the sensing module and replace it with a new or repaired module. This process is quick and simple, greatly shortening equipment downtime and maintenance cycle, and significantly reducing the complexity and overall cost of on-site maintenance. By employing V-groove 301 and clamping block 8, and through the locking design of V-groove 301 and lever-type eccentric wheel 302, modular installation that is fast, repeatable, high-precision, and highly reliable is achieved.
