Description

Technical Field

[0001] This invention belongs to the field of instrument installation tooling technology, specifically relating to an installation structure for intelligent thermal control instruments in power plants. Background Technology

[0002] In modern thermal and nuclear power plants, numerous intelligent thermal control instruments (such as intelligent pressure transmitters and intelligent temperature sensors) are used to monitor the unit's operating status in real time. The accuracy and reliability of their measurement data directly affect the safe, economical, and environmentally friendly operation of the unit. Currently, the field installation of intelligent thermal control instruments commonly faces the following problems: The installation and fixing methods are crude: they usually use simple angle steel welding or pipe clamp binding, which makes it difficult to adjust the installation position and angle, and makes it difficult to ensure that the instrument measuring probe is in the optimal measuring point (such as the center of the pipeline or where the medium is fully flowing), thus affecting the measurement accuracy.

[0003] Poor vibration resistance: Power plant environments are subject to a large amount of mechanical vibration from pumps, fans, and pipelines. Traditional rigid installation methods directly transmit vibration to precision instruments, resulting in increased sensor signal noise, zero drift, and even loosening and damage to internal components, thus shortening the instrument's lifespan.

[0004] Inconvenient maintenance and replacement: When instruments need periodic calibration or fault replacement, the disassembly process is cumbersome, often requiring the use of welding and cutting tools, which is labor-intensive and time-consuming, increasing the risk of unplanned unit shutdowns.

[0005] Disorganized cable management: Instrument signal lines and power lines are often laid and bundled haphazardly, which is not only unsightly, but also poses a risk of being burned by high-temperature pipelines or snagged by moving parts, affecting line safety and signal stability.

[0006] Insufficient environmental adaptability: Some instruments installed outdoors lack effective rainproof, dustproof, and condensation-proof measures. Harsh environments can easily lead to water ingress into the instrument junction box and short circuits caused by moisture on the circuit board.

[0007] Therefore, there is an urgent need for an integrated, modular installation structure for intelligent thermal control instruments that possesses excellent vibration resistance and environmental adaptability, in order to improve the installation quality, measurement stability, and maintenance convenience of the instruments.

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit disclosure. The described embodiments are some, but not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] like Figures 1 to 5 As shown, an embodiment of the present invention provides an installation structure for a smart thermal control instrument 3 in a power plant, including: a crossbeam frame 1, a first buffer assembly 4, a U-shaped mounting bracket 7, two sets of second buffer assemblies 8, and a cable management assembly 5; The first buffer assembly 4 is slidably connected to the top of the crossbeam frame 1 along the length of the crossbeam frame 1; The bottom of the U-shaped mounting bracket 7 is connected to the top of the first buffer assembly 4. The first buffer assembly 4 buffers the U-shaped mounting bracket 7 in the vertical direction. The opening of the U-shaped mounting bracket 7 faces upward. The U-shaped mounting bracket 7 has an installation space for installing the intelligent thermal control instrument 3. Two sets of second buffer components 8 are respectively disposed on the opposite side walls of the U-shaped mounting bracket 7. The two sets of second buffer components 8 are respectively used to connect the opposite sides of the intelligent thermal control instrument 3. The second buffer components 8 are used to buffer the vertical direction perpendicular to the intelligent thermal control instrument 3. The cable management component 5 is located on the side of the first buffer component 4. The cable management component 5 is used to store the cable of the intelligent thermal control instrument 3.

[0024] According to the installation structure of the power plant intelligent thermal control instrument 3 of the present invention, the U-shaped mounting bracket 7 enables quick installation and disassembly, greatly improving installation quality and maintenance efficiency; the first buffer component 4 can attenuate the mechanical vibration of power plant equipment or pipelines transmitted to the intelligent thermal control instrument 3, and the second buffer component 8 can attenuate the mechanical vibration of the U-shaped mounting bracket 7 transmitted to the intelligent thermal control instrument 3, effectively reducing mechanical damage, ensuring data accuracy, and extending the service life of the instrument; the cable management component 5 can standardize cable management and avoid potential wiring hazards, thus improving the overall operational reliability of the thermal control system.

[0025] like Figure 1 , Figure 2 As shown, in some embodiments of the present invention, one end of the crossbeam frame 1 is connected to an L-shaped hanging plate 11, and the L-shaped hanging plate 11 is provided with a plurality of connecting parts for connecting equipment or pipes. Specifically, the connecting parts can be connecting holes, and the L-shaped hanging plate 11 is fixed to the connecting equipment or pipe by the cooperation of bolts with the connecting holes, so as to realize the fixing of the power plant intelligent thermal control instrument 3 installation structure with other connecting equipment or pipes.

[0026] In some embodiments of the present invention, the invention further includes at least one guide rail 2 and a slide block 6. Specifically, the guide rail 2 is connected to the top of the crossbeam frame 1, and the extension direction of the guide rail 2 is the same as the length direction of the crossbeam frame 1 and perpendicular to the vertical direction. The slide block 6 cooperates with the guide rail 2 and is connected to the bottom of the first buffer assembly 4. The first buffer assembly 4 can drive the U-shaped mounting bracket 7 to slide along the length direction of the crossbeam frame 1 to adjust the position of the intelligent thermal control instrument 3 installed in the U-shaped mounting bracket 7 to adapt to the measurement needs of different positions.

[0027] In some embodiments of the present invention, the number of guide rails 2 is one. One guide rail 2, in conjunction with the slide block 6, can fulfill the sliding requirements of the first buffer component 4. Two or more guide rails 2, in conjunction with the slide block 6, can further improve the stability of the connection between the guide rails 2 and the slide block 6. In this embodiment, while considering the stability of the connection between the guide rails 2 and the slide block 6 and simplifying the structure, the installation structure of the power plant intelligent thermal control instrument 3 includes two guide rails 2, which are arranged in parallel, and the slide block 6 is in conjunction with the two guide rails 2. By having two parallel guide rails 2 in conjunction with the slide block 6, the stability of the sliding connection between the slide block 6 and the guide rails 2 can be improved, preventing the slide block 6 from detaching from the guide rails 2, thereby improving the installation stability of the power plant intelligent thermal control instrument 3 installation structure.

[0028] In some embodiments of the present invention, the cable management component 5 is connected to the slide 6, and the cable management component 5 is located on the side of the guide rail 2 to ensure that the cable conduit component does not affect the cooperation between the guide rail 2 and the slide 6.

[0029] like Figure 3As shown, in some embodiments of the present invention, the first buffer assembly 4 includes: a sleeve 41, a sliding column 42, a limiting plate 43, and a first spring 44. Specifically, the top of the sleeve 41 has an opening communicating with the internal space of the sleeve 41. The sleeve 41 is sleeved on the sliding column 42. The first end of the sliding column 42 extends from the opening at the top of the sleeve 41 to the outside of the sleeve 41. The first end of the sliding column 42 is connected to the bottom of the U-shaped mounting bracket 7. Specifically, the bottom of the U-shaped mounting bracket 7 is provided with a threaded cylinder 9. The outer wall of the first end of the sliding column 42 is provided with external threads. The connection between the U-shaped mounting bracket 7 and the sliding column 42 is achieved through the engagement of the threaded cylinder 9 and the external threads. The second end of the sliding column 42 and the limiting plate 43 are both located inside the sleeve 41. The second end of the sliding column 42 is connected to the limiting plate 43. The size of the limiting plate 43 is larger than the size of the opening of the sleeve 41, that is, the limiting plate 43 restricts the sliding column 42 from disengaging from the sleeve 41. The first spring 44 is disposed inside the sleeve 41, and is located between the limiting plate 43 and the bottom inner wall of the sleeve 41. The axial direction of the sleeve 41 is vertical, and the extension and retraction direction of the first spring 44 is vertical, so that the first buffer assembly 4 buffers the U-shaped mounting bracket 7 along the vertical direction.

[0030] In some embodiments of the present invention, the first buffer assembly 4 further includes a second spring 45. Specifically, the second spring 45 is disposed inside the sleeve 41 and sleeved on the slide column 42. The second spring 45 is located between the limiting plate 43 and the top inner wall of the sleeve 41, that is, between the limiting plate 43 and the annular limiting part in the vertical direction. The extension and contraction direction of the second spring 45 is vertical. By providing the second spring 45, the U-shaped mounting bracket 7 connected to the slide column 42 can be further buffered in the vertical direction. Through the synergistic effect of the first spring 44 and the second spring 45, the first buffer assembly 4 can have a good buffering effect.

[0031] In some embodiments of the present invention, the second buffer assembly 8 includes a metal gasket, a high-damping rubber layer, a butterfly spring, and a microporous elastic layer of polyurethane, arranged sequentially along the sidewall of the U-shaped mounting bracket 7 to the mounting space. By providing multiple buffer layers of different materials, the second buffer assembly 8 has a good buffering effect along the direction from one sidewall of the U-shaped mounting bracket 7 to the other sidewall.

[0032] like Figure 4As shown, in some embodiments of the present invention, the cable management component 5 includes: a storage box 51, an L-shaped pull-out plate 52, and a limiting plate 53. Specifically, the L-shaped pull-out plate 52 has a first plate 521 and a second plate 522 connected to each other. The first plate 521 and the second plate 522 are perpendicular to each other. The first plate 521 and the storage box 51 are movably connected and form a first telescopic member that is telescopic and retractable perpendicular to the sliding direction of the first buffer component 4. The telescopic direction of the first telescopic member is perpendicular to the vertical direction. The storage box 51 may have a space for accommodating empty... The structure allows the first plate 521 to be movably inserted into the storage box 51, or the first plate 521 to have a receiving space, and the storage box 51 to be movably inserted into the receiving space of the first plate 521. The first plate 521 has a plurality of through holes spaced apart along its length. The relative movement of the first plate 521 and the storage box 51 is achieved by the first knob bolt 54 on the storage box 51 cooperating with the different through holes on the first plate 521, that is, the extension and retraction of the first telescopic member is achieved to accommodate the storage of cables of different sizes.

[0033] The second plate 522 and the limiting plate 53 are movably connected to form a vertically extendable second telescopic member. The limiting plate 53 can be a structure with a receiving space, and the second plate 522 can be movably inserted into the storage box 51, or the second plate 522 has a receiving space, and the limiting plate 53 can be movably inserted into the receiving space of the second plate 522. The limiting plate 53 has multiple through holes spaced apart along its height direction, that is, multiple through holes spaced apart along the vertical direction. The relative movement between the limiting plate 53 and the second plate 522 is achieved by the second knob bolt 55 on the second plate 522 cooperating with different through holes on the limiting plate 53, that is, adjusting the height of the second telescopic member to accommodate cables of different sizes. The end of the limiting plate 53 away from the second plate 522 has multiple slots 531 for binding cables. Cables can be wound around the multiple slots 531 to bind and store the cables.

[0034] like Figure 5As shown, in some embodiments of the present invention, the cable management component 5 further includes: a stop bar 56. Specifically, the stop bar 56 has sliding ribs 561 on its opposite sides. The length direction of the sliding ribs 561 is the same as the sliding direction of the first buffer component 4. The limiting plate 53 has a limiting groove 532 at one end away from the L-shaped pull plate 52. The two opposite inner sidewalls of the limiting groove 532 have sliding grooves 533, which cooperate with the sliding ribs 561. Specifically, the limiting plate 53 has a plurality of slots 531 arranged at intervals along its length at one end of the second plate 522 away from the L-shaped pull plate, so as to form a plurality of protrusions at one end of the limiting plate 53 away from the second plate 522. The top of each protrusion has a limiting groove 532. The opposite sidewalls of each limiting groove 532 have sliding grooves 533. The two sliding ribs 561 on opposite sides of the stop bar 56 cooperate with the two sliding grooves 533 of each limiting groove 532. By setting the stop lever 56, the movement of the cable can be restricted, preventing the cable from coming out of the slot 531.

[0035] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
