Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly to a sensor fixing device and a fixing method suitable for complex pipelines. Background Art

[0002] If leakage or failure occurs in nuclear power valves and pipelines, it may lead to serious consequences such as leakage of radioactive substances and system shutdown. During the operation of industrial equipment (such as nuclear power valves and pipelines), by carrying out technologies such as vibration monitoring, temperature monitoring, and ultrasonic detection, staff can capture abnormal signals of the equipment in real time, so as to timely identify safety problems of nuclear power valves and pipelines. During the monitoring process, the stability of the sensor directly affects the accuracy of the monitoring.

[0003] In the prior art, there are multiple problems with existing sensor fixing devices in complex working conditions. Since the surfaces of the pipelines and valves of industrial equipment are usually irregular and affected by vibration, when fixing the sensor, it is difficult for the sensor to be stably attached to the pipeline and valve, resulting in a decrease in signal acquisition accuracy. At the same time, many traditional fixing devices require additional tools for installation, which is time-consuming and laborious, especially difficult to install effectively when the pipeline space is limited. And due to the single design of the fixing device, it is difficult to meet the adaptation requirements of multiple sensor models or complex equipment surfaces. Summary of the Invention

[0010] In some embodiments, the handheld grip is ergonomically designed, and the outer layer of the handheld grip is wrapped with a flexible heat-insulating material.

The limiting groove is used to place the wiring terminal of the sensor, and the limiting groove and the sensor connecting wire jointly limit the position of the sensor.

[0013] In some embodiments, the spring buffer structure includes a supporting flat plate and a spring. One end of the spring is connected to the bottom of the cylindrical groove, and the other end of the spring is connected to the supporting flat plate. The supporting flat plate supports the bottom of the sensor, and a buffer gasket is provided on the surface of the supporting flat plate.

[0014] In some embodiments, the spring has a compression stroke of 3 mm to 10 mm. The bottom end of the spring is fixed to the bottom of the cylindrical groove of the sensor fixing housing by means of a thread or a buckle, and the spring is made of steel.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figures 1 to 4As shown in the figure, the present invention proposes a sensor fixing device applicable to complex pipelines. The device includes a fixing rod 1, a sensor fixing housing 2, a spring buffer structure 3, and a limiting groove 4. The sensor fixing housing 2 is a hemispherical structure. A cylindrical groove is provided at the center inside the sensor fixing housing 2, which is used to accommodate and protect the sensor. A spring buffer structure 3 is provided at the bottom of the cylindrical groove. The spring buffer structure 3 supports the sensor and provides buffering for the sensor. One end of the outer arc surface of the sensor fixing housing 2 is connected to the fixing rod 1, and the other end of the fixing rod 1 is connected to a handheld grip. The inner opening plane of the sensor fixing housing 2 closely adheres to the measured surface during measurement.

[0030] The fixing rod 1 is a connecting body for connecting the handheld grip and the sensor fixing housing 2. The fixing rod 1 is connected to the sensor fixing housing 2 by threads or a buckle, and the fixing rod 1 is made of aluminum alloy or stainless steel. The fixing rod 1 is a threaded telescopic rod, and the telescopic length range of the fixing rod 1 is 50 cm to 150 cm. The fixing rod 1 adjusts its length by rotating the threads to adapt to different detection distances and space requirements. The handheld grip connected to the fixing rod 1 is designed according to ergonomics, and the outer layer of the handheld grip is wrapped with a flexible heat-insulating material.

[0031] The sensor fixing housing 2 is used to accommodate and protect the sensor, and realizes stable contact between the sensor and the detection surface through a spring structure. The sensor fixing housing 2 is a hemispherical structure. A cylindrical groove is provided at the center inside the sensor fixing housing 2, and the inner diameter of the cylindrical groove matches the outer dimensions of the sensor. The opening plane of the sensor fixing housing 2 fits the surface of the pipeline to be detected. A limiting groove 4 is provided on the sensor fixing housing 2, and the limiting groove 4 communicates with the cylindrical groove. The limiting groove 4 is used to place the wiring terminal of the sensor. The limiting groove 4 and the sensor connecting wire simultaneously limit the position of the sensor. The limiting groove 4 prevents the sensor from moving upward or sliding horizontally during the detection process. The opening size of the limiting groove 4 matches the geometric shape of the sensor wiring terminal, forming a three-dimensional constraint through physical contact. When the sensor is embedded in the cylindrical groove, its wiring terminal is completely embedded in the limiting groove 4, and the wiring terminal of the sensor is restricted by the side wall of the limiting groove 4 to prevent the sensor from rotating in the groove. At the same time, the connecting wire of the sensor wiring terminal is arranged in an "S" shape in the limiting groove, and the friction force generated by the self-weight of the cable assists in fixing the position of the sensor. At the same time, anti-slip tooth patterns provided in the limiting groove 4 can increase the friction coefficient to avoid displacement caused by vibration. Buffer gaskets are pasted on the inner wall and bottom of the sensor fixing housing 2, and the flexible anti-slip gaskets increase the friction force and protect the surface of the sensor.

[0032] The spring buffer structure 3 provides support and buffering for the sensor, ensuring stable contact with the detection surface and absorbing the impact of equipment vibration on detection. The spring buffer structure 3 includes a support flat plate and a spring. One end of the spring is connected to the bottom of the cylindrical groove, and the other end of the spring is connected to the support flat plate. The support flat plate supports the bottom of the sensor, and a buffer gasket is provided on the surface of the support flat plate. The spring has a compression stroke of 3 mm to 10 mm, which can adapt to the flatness deviation of different surfaces. At the same time, the spring has a buffering effect, which can reduce the interference of vibration on detection. The bottom end of the spring is fixed to the cylindrical groove base of the sensor fixed housing 2 by means of threads or snaps to ensure that its position does not shift during use. The spring is made of durable steel and has the elastic retention performance for long-term use. The pressure exerted by the spring can stably attach the sensor to the detection surface, providing continuous and reliable contact force, thus ensuring the accuracy of detection and the stability of signal acquisition. Even under high vibration or complex working conditions, the working effect of the device can be ensured. At the same time, through the spring buffer design, this sensor fixing device can be adapted to a variety of sensor models.

[0033] The present invention proposes a sensor fixing device and a fixing method suitable for complex pipelines. Through the combination of a spring buffer structure and a limit design, the device ensures that the sensor can be stably attached under vibration and irregular surface conditions. At the same time, the spring provides continuous pressure to avoid detection deviation, significantly improving the stability and accuracy of detection.

[0034] The present invention proposes a sensor fixing method suitable for complex pipelines, and the method includes:

[0035] Step 1: The operator installs the sensor inside the sensor fixed housing 2. The bottom of the sensor contacts the support flat plate of the spring buffer structure 3, the outer wall of the sensor contacts the inner wall of the cylindrical groove of the sensor fixed housing 2, and the wiring terminal of the sensor is placed in the limit groove 4 of the sensor fixed housing 2;

[0036] Step 2: The operator connects the sensor to the acquisition system, and the wiring of the sensor passes through the limit groove 4 to connect to the acquisition system;

[0037] Step 3: The operator adjusts the length of the fixing rod 1, holds the connection handle of the fixing rod 1, the opening plane of the sensor fixed housing 2 is closely attached to the measured pipeline or valve, and the sensor starts to measure the signal.

[0038] The above embodiments only express several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
