Technical Field
[0001] This utility model relates to the field of boiler detection technology in thermal power plants, specifically to an installation structure for a digital monitoring device for boiler wall expansion. Background Technology
[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. To ensure the safety of the boiler during long-term heating, a set of digital boiler expansion monitoring devices is usually set up. Its main function is to detect the expansion obstruction in time when the boiler operating conditions are disturbed, prevent equipment damage, and provide guidance for equipment operation and management.
[0003] For example, a digital monitoring device for boiler wall expansion in a thermal power plant, as described in application number CN202220743575.2, includes a displacement sensor, a fixing rod, an acrylic scale panel, and an industrial capacitive screen. The displacement sensor is fixed to a monitoring point on the boiler wall by the fixing rod, ensuring that its displacement is consistent with that of the monitoring point on the boiler. The acrylic scale panel is fixed to the industrial capacitive screen and maintains consistent scale, working in conjunction with the displacement sensor to measure the three-dimensional expansion displacement data of the boiler wall under working conditions. Compared with traditional monitoring devices, the digital monitoring device for boiler wall expansion in a thermal power plant provided by this utility model can effectively reduce human error and greatly improve work efficiency.
[0004] When using the digital monitoring device for boiler wall expansion proposed in the aforementioned patent, the monitoring device needs to be installed on one side of the outer wall of the boiler. The bottom of the monitoring device is fixed to the ground. In order to improve the stability of the monitoring device, a protective shell is fixedly installed on the outer surface of the monitoring device. This setup makes it quite troublesome to repeatedly disassemble and reinstall the fixed protective shell when the monitoring device needs routine maintenance.
[0005] Therefore, we proposed an installation structure for a digital monitoring device for boiler wall expansion to address the aforementioned issues. Utility Model Content
[0006] The purpose of this utility model is to provide an installation structure for a digital monitoring device for boiler wall expansion, in order to solve the problem mentioned in the background art that in order to improve the stability of the monitoring device, a protective shell is fixedly installed on the outer surface of the monitoring device. This setup makes it troublesome to repeatedly disassemble and install the fixedly installed protective shell when the monitoring device needs routine maintenance.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a digital monitoring device for boiler wall expansion, comprising a fixed base and an industrial capacitor screen fixedly installed on the upper end of the fixed base. An acrylic scale panel is provided on the upper end of the industrial capacitor screen, and an LVD displacement sensor is provided on the upper end of the acrylic scale panel. A fixing rod is connected to the middle of one end of the LVD displacement sensor, and the other end of the fixing rod is connected to the boiler. A protective cover is provided around the upper end of the fixed base, and clamping components are threadedly fixedly installed in the middle of the upper end of the fixed base. The clamping components are designed to facilitate the installation and removal of the protective cover.
[0008] The clamping assembly includes a propulsion mechanism and a drive mechanism disposed at one end of the propulsion mechanism. A fitting plate is fixedly installed on the upper side of one side of the drive mechanism. The position of the drive mechanism and the fitting plate can be moved by the movement of the propulsion mechanism.
[0009] Preferably, the fixed base includes a base plate and square through slots at the four upper corners of the base plate, with limiting grooves formed in the middle of the inner walls of the square through slots.
[0010] Preferably, a hollow ring is movably installed in the inner cavity of the square through slot, and a locking block is fixedly installed on the outer wall of the hollow ring.
[0011] Preferably, the upper perimeter of the base plate is provided with an insertion groove in the middle of its surrounding area, and the inner walls of the insertion grooves are provided with sliding grooves in the middle of their respective sides.
[0012] Preferably, the propulsion mechanism includes a threaded rod and a bearing disposed at one end of the threaded rod.
[0013] Preferably, the driving mechanism includes an insertion block and sliding blocks respectively fixedly installed on the middle of both sides of the outer wall of the insertion block. The upper middle part of the sliding block is provided with a placement groove, and a roller is movably installed in the inner cavity of the placement groove through a movable shaft.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The operator places the protective cover around the upper part of the fixed base, and then rotates the threaded rod in the forward direction to move the bearing, the insertion block and the fitting plate to their respective positions. This causes the fitting plate around the upper part of the fixed base to clamp and fix the lower end of the protective cover. When it is necessary to remove the protective cover, it can be done by simply rotating the threaded rod in the reverse direction. Installation and disassembly are convenient.
[0016] 2. By passing a screw through a hollow ring, the bottom of the screw is aligned with the circular groove on the object being fixed. During this process, the operator can move the hollow ring to drive the locking block to slide and install it in the inner cavity of the limiting groove. This allows the hollow ring to drive the screw and the circular groove on the object being fixed to be aligned and fixed. This design eliminates the need to re-cut the circular groove if it deviates from its original shape, making installation and fixing convenient. Attached Figure Description

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.
[0023] Example 1: Please refer to Figures 1-4The installation structure for a digital monitoring device for boiler wall expansion includes a fixed base 1 and an industrial capacitive screen 2 fixedly installed on the upper part of the fixed base 1. An acrylic scale panel 3 is provided on the upper part of the industrial capacitive screen 2, and an LVD displacement sensor 4 is provided on the upper part of the acrylic scale panel 3. A fixing rod 5 is connected to the middle of one end of the LVD displacement sensor 4, and the other end of the fixing rod 5 is connected to the boiler 7. A protective cover 6 is provided around the upper part of the fixed base 1, and a clamping assembly 8 is threadedly fixed to the middle of the upper part of the fixed base 1. The clamping assembly 8 is designed to facilitate the installation and removal of the protective cover 6.
[0024] An industrial capacitive screen 2, which is horizontally placed at the movable lower end under the LVD displacement sensor 4, is used to measure the displacement distance of the boiler wall along the X and Y axes. An acrylic scale panel 3 is fixed on the surface of the industrial capacitive screen 2. Together with the LVD displacement sensor 4, it completes the three-dimensional expansion data measurement. The LVD displacement sensor 4 is fixedly connected to the boiler expansion monitoring point of the boiler 7 by a fixing rod 5.
[0025] The structure and working principle of the industrial capacitive screen 2, acrylic scale panel 3, LVD displacement sensor 4, fixing rod 5, and boiler 7 are the same as those of the acrylic scale panel, industrial capacitive screen, LVDT displacement sensor, fixing rod, base, glass cover, and boiler in publication number CN217303849U, and will not be described again here.
[0026] The clamping assembly 8 includes a pushing mechanism 81 and a driving mechanism 82 disposed at one end of the pushing mechanism 81. A fitting long plate 83 is fixedly installed on the upper side of one side of the driving mechanism 82. The driving mechanism 82 and the fitting long plate 83 can move in position by moving the pushing mechanism 81.
[0027] An insertion groove 16 is provided in the middle of the upper perimeter of the base plate 11. A sliding groove 17 is provided in the middle of the two sides of the inner wall of the insertion groove 16. The insertion block 821 is movably installed in the inner cavity of the insertion groove 16, and the sliding block 822 is movably installed in the inner cavity of the sliding groove 17.
[0028] The propulsion mechanism 81 includes a threaded rod 811 and a bearing 812 disposed at one end of the threaded rod 811. The threaded rod 811 is threadedly connected to a threaded groove opened in the middle of one end of the inner wall of the insertion groove 16.
[0029] The driving mechanism 82 includes an insertion block 821 and sliding blocks 822 respectively fixedly installed on the middle of the outer wall of the insertion block 821. The upper middle of the sliding block 822 is provided with a mounting groove 823. A roller 824 is movably installed in the inner cavity of the mounting groove 823 through a movable shaft. The setting of the roller 824 is to improve the smoothness of the sliding block 822 sliding in the inner cavity of the sliding groove 17.
[0030] In this embodiment: After fixing the base 1, the operator can place the protective cover 6 around the upper part of the base 1. By rotating the threaded rod 811 in the forward direction, the bearing 812, the insertion block 821, and the fitting plate 83 are moved to their respective positions. At the same time, when the insertion block 821 moves, it will drive the sliding block 822 and the roller 824 fixed on both sides of its outer wall to slide in the inner cavity of the sliding groove 17. This allows the fitting plate 83, which is set around the upper part of the base 1, to clamp and fix the lower part of the outer wall of the protective cover 6. This arrangement allows the operator to remove the protective cover 6 by simply rotating the threaded rod 811 in the reverse direction. The installation and removal are convenient and will not damage the protective cover 6.
[0031] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 The fixed base 1 includes a base plate 11 and square through slots 12 formed at the four corners of the upper end of the base plate 11. Limiting grooves 13 are formed in the middle of the four sides of the inner wall of the square through slots 12. The limiting grooves 13 are set to provide limiting support for the hollow ring 14.
[0032] A hollow ring 14 is movably installed in the inner cavity of the square through slot 12. A locking block 15 is fixedly installed on the outer wall of the hollow ring 14. The locking block 15 is movably installed in the inner cavity of the limiting slot 13 to limit the movement of the hollow ring 14.
[0033] In this embodiment: When fixing the base 1, the operator opens four corresponding circular slots on the object to be fixed according to the setting position of the square through slots 12 at the four corners of the upper end of the base 1. The screw passes through the hollow ring 14 and the bottom of the screw is aligned with the circular slots on the object to be fixed. During this process, the operator can move the hollow ring 14 to drive the locking block 15 to slide and install it in the inner cavity of the limiting groove 13, so that the hollow ring 14 drives the screw and the circular slots on the object to be fixed to be aligned and fixed. This setting can make it convenient to install and fix the object without having to re-open the circular slots if the opening of the circular slots on the object is off.
[0034] Working principle: Based on the positions of the square through slots 12 at the four corners of the upper end of the fixed base 1, the operator creates four corresponding circular slots on the object to be fixed. A screw passes through the hollow ring 14, aligning the bottom of the screw with the circular slots on the object. During this process, the operator can move the hollow ring 14 to slide the locking block 15 into the inner cavity of the limiting groove 13, thus allowing the hollow ring 14 to align the screw with the circular slots on the object. This design eliminates the need to re-create the slots if they deviate from their original positions. After fixing the fixed base 1, the protective cover 6 can be placed... The threaded rod 811 is placed around the upper end of the fixed base 1, and then rotated clockwise to move the bearing 812, the insertion block 821 and the fitting plate 83 to their respective positions. At the same time, when the insertion block 821 moves, it will drive the sliding block 822 and the roller 824 fixed on both sides of its outer wall to slide in the inner cavity of the sliding groove 17. This allows the fitting plate 83, which is set around the upper end of the fixed base 1, to clamp and fix the lower end of the outer wall of the protective cover 6. This setting allows the operator to remove the protective cover 6 by simply rotating the threaded rod 811 in the reverse direction without damaging the protective cover 6.
