Description

Technical Field

[0001] This utility model relates to the field of boiler expansion monitoring technology, specifically to a sensor mounting bracket and its reflector box system for monitoring three-dimensional expansion of a boiler. Background Technology

[0002] As power plants shift from extensive to intensive management of generator equipment, data records of thermal expansion of equipment such as pipes and headers are also being managed. This data is helpful in understanding the causes of stress in the equipment. In order to accurately determine whether various pipes, headers, and containers are obstructed, whether the distribution is uniform, and whether they expand as required when heated, it is necessary to install expansion indicators at specific locations on the equipment.

[0003] A search revealed a boiler expansion displacement online monitoring system based on laser displacement sensors, published under announcement number CN 217210745 U. This system includes a three-dimensional displacement monitoring component, a fixed support, a connecting rod, and a scale monitoring device. The connecting rod is horizontal, with its left and right ends perpendicularly connected to the fixed support and the measuring point on the boiler, respectively. The three-dimensional displacement monitoring component includes three laser displacement sensors, each positioned perpendicularly to one of the three ends of the fixed support. The laser displacement sensors are connected to a signal receiving device via an analog-to-digital converter, and the signal receiving device is connected to a computer terminal. Three scale monitoring devices are provided, each positioned at the corresponding monitoring location of the three laser displacement sensors. Each scale monitoring device includes a base, a support rod, a cross slide rail, and a scale dial. The cross slide rail is used to adjust the position of the scale dial, ensuring that the monitoring point of the laser displacement sensor coincides with the center point of the scale dial. This system enables simultaneous online and on-site monitoring.

[0004] However, the above technologies still have some shortcomings in use. The fixed installation position and angle of the sensors make it difficult to adapt to the spatial layout differences of different boiler models and monitoring points, and the installation and debugging are difficult. The connection between the sensors and the brackets is mostly rigid, which makes the operation cumbersome and affects the maintenance efficiency when the sensors need to be repaired, calibrated or replaced. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sensor mounting bracket and its reflector box system for monitoring the three-dimensional expansion of boilers. This solves the problems of fixed sensor installation positions and angles, difficulty in adapting to spatial layout differences of different boiler models and monitoring points, and high installation and debugging difficulty; the connection between sensors and brackets is mostly rigid, which makes the operation cumbersome and affects maintenance efficiency when sensors need to be inspected, calibrated or replaced.

[0006] This utility model provides the following technical solution: a sensor mounting bracket and its reflector box system for monitoring three-dimensional expansion of a boiler, including a mounting plate and three laser displacement sensors. A rotating rod is rotatably mounted on the surface of the mounting plate. A sleeve is fixedly connected to one end of the rotating rod. A connecting rod is slidably mounted inside the sleeve. A three-dimensional bracket is fixedly connected to one end of the connecting rod. Mounting boxes are fixedly mounted on all three ends of the three-dimensional bracket.

[0007] Each mounting box has a set of movable grooves on its surface. A bidirectional lead screw is rotatably installed between the two inner side walls of each mounting box. A set of lead screw sleeves is threaded onto the surface of each bidirectional lead screw. A clamping plate is fixedly connected to the surface of each lead screw sleeve.

[0008] Preferred technical solution 1: A sliding rod is fixedly connected between the two inner side walls of each mounting box, and two sliding sleeves are slidably sleeved on the surface of each sliding rod. Each sliding sleeve can be fixedly connected to the corresponding clamping plate, and the sliding sleeve and the lead screw sleeve can move inside the corresponding movable groove.

[0009] Preferred technical solution 2: A set of through holes are formed on the surface of the sleeve, and a locking rod is slidably fitted inside each of the through holes. A row of locking grooves matching the locking rods are formed on the surface of the connecting rods, and a spring is fitted on one end of the outer side of each locking rod.

[0010] Preferred technical solution 3: A pull plate is fixedly connected between the outer ends of a group of the clamping rods. The pull plate is made of iron, and a magnet is fixedly connected to the surface of the sleeve.

[0011] Preferred technical solution four: One end of the rotating rod extends into the interior of the mounting plate and is fixedly connected to a worm gear; a worm is rotatably installed between the inner walls of the mounting plate; the worm meshes with the worm gear; one end of the worm extends into the exterior of the mounting plate and is fixedly connected to an operating disc; one end of each bidirectional lead screw extends into the exterior of the connected mounting box and is fixedly connected to a rotating disc.

[0012] Preferred technical solution five: The surface of the mounting plate is fixedly connected with multiple fixing plates, and each fixing plate has a mounting hole on its surface.

[0013] Compared with the prior art, this utility model provides a sensor mounting bracket and its reflective box system for monitoring the three-dimensional expansion of a boiler, which has the following advantages: In use, the device is installed on the boiler through a mounting plate and a fixing plate. Then, by rotating the worm gear, the worm wheel and the rotating rod are driven to rotate, thereby driving the sleeve and the three-dimensional bracket to rotate, adjusting the position of the laser displacement sensor installed on the mounting box. At the same time, by pulling the pull plate upward, the locking rod is disengaged from the slot, which can release the locking of the sleeve and the connecting rod. Then, the position of the three-dimensional bracket can be further adjusted by pulling the connecting rod. This makes it convenient and quick to install in different environments.

[0014] When the laser displacement sensor needs to be removed for storage or replacement after use, the double-acting lead screw is rotated to move the lead screw sleeve, thereby moving the clamping plates in opposite directions, releasing the lock on the laser displacement sensor, and then it can be removed for inspection or replacement, which is convenient and quick.

[0015] This utility model enables multi-angle and multi-position adjustment of the sensor through a worm gear and sleeve connecting rod, adapting to different boiler environments; the bidirectional lead screw drives the clamping plate to achieve quick sensor disassembly, facilitating inspection and replacement and improving installation and maintenance efficiency.

[0023] Each mounting box 6 has a set of movable grooves 7 on its surface. A bidirectional lead screw 8 is rotatably installed between the two inner side walls of each mounting box 6. A set of lead screw sleeves 9 are threaded onto the surface of each bidirectional lead screw 8. A clamping plate 10 is fixedly connected to the surface of each lead screw sleeve 9.

[0024] Example 2: The difference between this example and Example 1 is that each mounting box 6 has a sliding rod 12 fixedly connected between its two inner side walls, and two sliding sleeves 13 are slidably sleeved on the surface of each sliding rod 12. Each sliding sleeve 13 can be fixedly connected to the corresponding clamping plate 10, and the sliding sleeve 13 and the lead screw sleeve 9 can move inside the corresponding movable groove 7.

[0025] Example 3: The difference between this example and Example 1 is that the sleeve 2 has a set of through holes 14 on its surface, and each through hole 14 has a locking rod 15 slidably fitted inside it. The connecting rod 4 has a row of locking grooves 16 that match the locking rods 15 on its surface, and each locking rod 15 has a spring 17 fitted on one side of its outer end.

[0026] Example 4: The difference between this example and Example 1 is that a pull plate 18 is fixedly connected between the outer ends of a set of levers 15. The pull plate 18 is made of iron, and a magnet 19 is fixedly connected to the surface of the sleeve 2.

[0027] Example 5: The difference between this example and Example 1 is that one end of the rotating rod 11 extends into the interior of the mounting plate 1 and is fixedly connected to the worm gear 20. A worm 21 is rotatably installed between the inner walls of the mounting plate 1. The worm 21 meshes with the worm gear 20. One end of the worm 21 extends into the exterior of the mounting plate 1 and is fixedly connected to the operating plate. One end of each bidirectional lead screw 8 extends into the exterior of the connected mounting box 6 and is fixedly connected to the rotating plate.

[0028] Example 6: The difference between this example and Example 1 is that multiple fixing plates 22 are fixedly connected to the surface of the mounting plate 1, and each fixing plate 22 has a mounting hole on its surface.

[0029] In summary, the sensor mounting bracket and its reflector box system for monitoring the three-dimensional expansion of the boiler are improvements on the fixed bracket in the prior art document CN 217210745 U. The specific detection and monitoring methods are the same as those in the prior art document. As prior art, they will not be described in detail here.

[0030] In use, the device is installed on the boiler via the mounting plate 1 and the fixing plate 22. Then, by rotating the worm gear 21, the worm wheel 20 and the rotating rod 11 are driven to rotate, thereby driving the sleeve 2 and the three-way bracket 5 to rotate, adjusting the position of the laser displacement sensor 3 installed on the mounting box 6. At the same time, by pulling the pull plate 18 upward, the locking rod 15 is disengaged from the slot 16, which releases the lock on the sleeve 2 and the connecting rod 4. Then, the connecting rod 4 can be pulled to further adjust the position of the three-way bracket 5, making it convenient and quick to install in different environments.

[0031] When the laser displacement sensor 3 needs to be disassembled for storage or replacement after use, the double-acting lead screw 8 is rotated to move the lead screw sleeve 9, thereby moving the clamping plate 10 in opposite directions, releasing the lock on the laser displacement sensor 3, and then it can be disassembled for inspection or replacement, which is convenient and quick.

[0032] This utility model enables multi-angle and multi-position adjustment of the sensor through a worm gear and sleeve connecting rod, adapting to different boiler environments; the bidirectional lead screw drives the clamping plate to achieve quick sensor disassembly, facilitating inspection and replacement and improving installation and maintenance efficiency.
