Description

Technical Field

[0001] The present invention relates to the technical field of sensor installation, and in particular to a sensor fixing device. Background Art

[0002] Sensors are devices that sense and detect physical or chemical quantities and convert them into measurable electrical signals or other usable output signals. They are widely used in technical fields such as industrial automation, smart homes, healthcare, and transportation. To improve the accuracy and long-term reliability of data collection, sensors must be stably and securely mounted. If sensors are not securely fixed, measurement deviations can occur, leading to system instability and increased accident rates.

[0003] In industrial production and condition monitoring, sensors are widely used on various pipelines to monitor temperature, pressure, flow, and locate leaks. However, traditional sensor installation methods typically rely on magnetic adsorption or direct welding to the pipe. This is unsuitable for pipes made of non-magnetic materials such as plastic, aluminum alloy, and stainless steel, significantly limiting their applicability. While direct welding of sensors to the pipe offers greater stability, the welding process can compromise the pipe's structural strength and even create safety hazards such as leaks.

[0004] Therefore, existing sensor fixtures lack flexibility and cannot adapt to pipes of different materials and shapes. Moreover, the fixtures need to be completely replaced for different sensor models, which increases installation costs. Summary of the Invention

The two magnetic clamps clamp and fix the sensor by mutual magnetic attraction.

[0008] Preferably, a pulling ring is welded to the upper surface of the second connecting rod, and the pulling ring is used to separate the sensor from the magnetic clamp.

[0009] Preferably, the pulling ring includes a ring body and a welding neck, the welding neck is provided with a first circular hole, the ring body is connected to the welding neck based on the first circular hole, and the end of the welding neck is welded to the upper surface of the second connecting rod.

[0011] Preferably, the pipe clamp is an open annular structure, and a locking bolt is provided at the opening of the pipe clamp. The locking bolt is used to adjust the opening size of the pipe clamp to adjust the diameter of the pipe clamp.

[0012] Preferably, an anti-slip pad is provided on the inner wall of the pipe clamp.

[0013] Preferably, the first connecting rod is a telescopic connecting rod, comprising an inner tube and an outer tube, wherein the outer tube is nested outside the inner tube, and an anti-slip gear and a friction plate are provided on the inner wall of the outer tube so that the inner tube is locked with the outer tube when pulled.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, an embodiment of the present invention provides a sensor fixing device. The sensor fixing device has a symmetrical structure and includes two pipe clamps 1, two first connecting rods 2, two second connecting rods 3, and two magnetic clamps 4. The two pipe clamps 1 are fixed to the pipeline at intervals along the pipeline's axial direction. The outer wall of the pipe clamp 1 is fixedly connected to the bottom end of the first connecting rod 2. The top end of the first connecting rod 2 is rotatably connected to one end of the second connecting rod 3. The other end of the second connecting rod 3 is detachably connected to the magnetic clamp 4. The two magnetic clamps 4 clamp the sensor in place through mutual magnetic attraction.

[0024] By placing the symmetrically arranged pipe clamp 1 on the pipe and adjusting the rotation angle between the second connecting rod 3 and the first connecting rod 2, the installation angle of the sensor can be easily adjusted. The two magnetic clamps are symmetrically arranged, and the sensor is fixed to the pipe based on the mutual magnetic attraction. At the same time, the detachable connection design of the second connecting rod 3 and the magnetic clamp 4 makes the installation and removal of the magnetic clamp 4 simple and quick. Users can choose different shapes of magnetic clamps 4 to adapt to different sensor models without having to replace the entire fixture, which greatly reduces installation costs and time costs.

[0025] Exemplarily, the outer wall of the pipe clamp 1 and the bottom end of the first connecting rod 2 are fixed together based on a welding process, and the second connecting rod 3 and the magnetic clamp 4 are detachably connected based on threads.

[0026] In the embodiment of the present invention, a pulling ring 31 is welded to the upper surface of the second connecting rod 3 , and the pulling ring 31 is used to separate the sensor and the magnetic clamp 4 .

[0027] For example, the staff connects the tool hook to the pulling ring 31, and by pulling the tool hook, transmits the pulling force to the second connecting rod 3, and the second connecting rod 3 drives the magnetic clamp 4 to move, thereby separating the magnetic clamp 4 from the sensor in a non-contact manner.

[0028] In the embodiment of the present invention, the pulling ring 31 includes a ring body and a welding neck. The welding neck has a first circular hole. The ring body is connected to the welding neck based on the first circular hole. The end of the welding neck is welded to the upper surface of the second connecting rod.

[0029] This allows the ring to rotate to a certain degree around the first circular hole, increasing its flexibility. When the sensor needs to be separated from the magnetic fixture 4, workers can more easily insert the tool hook through the ring and perform the pulling action. At the same time, the welded neck design strengthens the connection between the pull ring 31 and the second connecting rod 3, ensuring that it will not loosen or fall off during the pulling process. This structural design not only improves the ease of operation of the sensor fixture, but also ensures its stability and reliability during use.

[0030] like Figure 2 As shown, in the embodiment of the present invention, a second circular hole is opened on the upper surface of the second connecting rod 3; the sensor fixing device also includes a pull rope 32, one end of the pull rope 32 is fixed in the second circular hole, and the other end of the pull rope 32 extends out of the second circular hole. The sensor and the magnetic clamp 4 can be separated by the pull rope 32.

[0031] For example, the sensor is installed underground, with one end of a pull rope 32 secured to the second circular hole of the second connecting rod 3, and the other end secured to the inner wall of the well. When personnel need to detach the sensor, they pull the pull rope 32 to separate the sensor from the sensor fixture at the wellhead, facilitating subsequent maintenance and avoiding work in confined spaces.

[0032] It should be understood that the design of the pull rope 32 and the brick pull ring 31 makes the sensor fixture more flexible and convenient to use. In actual operation, workers can easily detach the sensor from the magnetic fixture 4 by pulling the rope 32 or the brick pull ring 31, eliminating the need to enter the well or perform tedious operations in confined spaces. This design not only improves work efficiency but also significantly reduces operational risks, ensuring worker safety.

[0033] In the embodiment of the present invention, the pipe clamp 1 is an open annular structure. A locking bolt is provided at the opening of the pipe clamp 1. The locking bolt is used to adjust the opening size of the pipe clamp 1 to adjust the diameter of the pipe clamp 1.

[0034] In this way, pipe clamp 1 can adapt to pipes of varying diameters, enhancing the versatility and flexibility of the sensor fixture. By tightening the locking bolt, pipe clamp 1 can be securely fastened to the pipe, ensuring the stability of the sensor fixture during use. Furthermore, the open design of pipe clamp 1 facilitates installation and removal, improving work efficiency.

[0035] In this embodiment of the present invention, to enhance the stability and durability of the device, pipe clamp 1 is made of high-strength material, ensuring that it is not easily deformed or damaged during prolonged use. The inner wall of pipe clamp 1 is provided with an anti-slip pad made of a high-friction rubber material. This pad increases the friction between pipe clamp 1 and the pipe, preventing relative slip between pipe clamp 1 and the pipe due to external forces during use, thereby further ensuring the stability of the sensor fixture.

[0036] At the same time, the provision of the anti-slip pad can also play a certain protective role on the pipeline, preventing the pipe clamp 1 from scratching or wearing the pipeline, thereby extending the service life of the pipeline. In addition, the anti-slip pad is made of rubber material and has a certain elasticity and cushioning effect. It can absorb and disperse the impact of external forces on the sensor to a certain extent, protecting the sensor from damage.

[0037] In this embodiment of the present invention, the first connecting rod 2 is a telescopic connecting rod comprising an inner tube and an outer tube. The outer tube is nested within the inner tube. The inner wall of the outer tube is provided with anti-slip gears and friction plates to lock the inner tube with the outer tube when extended or retracted. This allows the length of the first connecting rod 2 to be adjusted according to actual needs, enhancing the adaptability and flexibility of the sensor fixture.

[0038] To adjust the sensor's position, simply pull the inner tube. The anti-slip gear and friction plate work together to keep the inner tube stably positioned, eliminating the need for additional locking devices. This design not only simplifies the operation process but also improves work efficiency. Furthermore, the telescopic connecting rod facilitates installation and commissioning in confined spaces, further expanding the application range of the sensor fixture.

[0039] In this embodiment of the present invention, the magnetic clamp 4 comprises a rod and a clamping jaw. One end of the rod is provided with a threaded connection for threaded connection with the second connecting rod 3. The other end of the rod is detachably connected to the clamping jaw, which is embedded with a magnet. This allows the magnetic clamp 4 connected to the second connecting rod 3 to be replaced via the threaded connection. Furthermore, the detachable connection between the rod and the clamping jaw facilitates replacement of the clamping jaw of the magnetic clamp 4.

[0040] This detachable magnetic fixture 4 allows for flexible selection of jaws of varying sizes or types to accommodate sensors of varying shapes and materials, further enhancing the versatility and practicality of the sensor fixture. Furthermore, the magnets embedded within the jaws securely hold the sensor, ensuring stability and accuracy during measurement. Furthermore, the detachable design of the magnetic fixture 4 facilitates cleaning and maintenance, extending the device's service life.

[0041] In this embodiment of the present invention, the first connecting rod 2 and the second connecting rod 3 are connected by a bearing, allowing for adjustment of the angle between them. This allows for greater flexibility in complex environments, adapting to installation requirements at varying angles. The bearing connection design allows users to easily adjust the angle between the first connecting rod 2 and the second connecting rod 3, allowing the second connecting rod 3 to rotate 360 degrees relative to the first connecting rod 2, ensuring the sensor can be precisely secured in the desired position. This design not only improves installation convenience but also enhances the adaptability and flexibility of the device.

[0042] As can be seen from the above technical solution, the present invention discloses a sensor fixing device. The sensor fixing device has a symmetrical structure and includes two pipe clamps, two first connecting rods, two second connecting rods, and two magnetic clamps. The outer wall of the pipe clamp is welded to the bottom end of the first connecting rod. The top end of the first connecting rod is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is embedded with threads, and the magnetic clamp is connected to the second connecting rod via the threads. The two magnetic clamps secure the sensor through mutual magnetic attraction.

[0043] The sensor fixing device provided by the present invention not only realizes a sensor fixing method that does not require welding or punching in the pipeline, but also greatly improves the flexibility and applicability of sensor installation. The device uses the magnetic attraction of a magnetic clamp to fix the sensor, regardless of the pipeline material, and is applicable to both magnetic and non-magnetic pipelines. At the same time, by adjusting the opening size of the pipe clamp, it can adapt to pipelines of different diameters, further expanding the scope of application of the device. In addition, the detachable design of the magnetic clamp allows the device to be adapted to a variety of different types of sensors, avoiding the problem of needing to replace the entire fixing device due to different sensor models, thereby reducing installation costs.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
