Description

Technical Field

[0001] This utility model relates to the field of transmitter protection technology, specifically a protection structure for a dual-output pressure transmitter. Background Technology

[0002] In the field of industrial process control, when dual-output pressure transmitters are exposed to mechanical shock, vibration, and temperature changes for a long time, traditional protective structures have several key defects: designs using rubber gaskets or springs for mechanical buffering are prone to aging and wear, resulting in loss of protective function; at the same time, high-frequency vibration can accelerate fatigue fracture of internal circuit board solder joints, threatening equipment reliability; although rigid housings have shock resistance, the rigidity of the material amplifies the transmitted stress, causing zero-point drift of the sensor and affecting measurement accuracy; welded or one-piece molded housing structures lack maintainability, requiring the entire equipment to be replaced in case of failure, resulting in high downtime costs. In view of this, in-depth research was conducted to address the above problems, leading to this case. Summary of the Invention

[0003] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a dual-output pressure transmitter, comprising a transmitter, with a protective structure mounted on the outer side of the transmitter. The protective structure includes a pair of fitted half-tube barrels, each half-tube barrel having an I-shaped cross-section. A connecting fixing plate is mounted on each half-tube barrel, with multiple connecting fixing plates arranged along the outer side of the half-tube barrels. These multiple connecting fixing plates are connected by bolts. A semi-circular ring limiting block is mounted on each half-tube barrel, with multiple semi-circular ring limiting blocks mounted on the half-tube barrels. A buffer is mounted on the inner side of each semi-circular ring limiting block. The buffer includes a telescopic compression block. A plurality of telescopic grooves are formed on the semi-circular ring limiting block. The cross-sections of the telescopic grooves and the telescopic compression block are convex. Multiple telescopic compression blocks are movably inserted into the inner side of the telescopic grooves. A metal semi-circular rod is mounted on the semi-circular ring limiting block. Multiple metal rods are mounted on the metal semi-circular rod, which is connected to the metal semi-circular rod and the telescopic grooves. Telescopic magnet blocks are mounted on the metal semi-circular rod and the telescopic compression block. A compression buffer arc block is mounted on the telescopic compression block. A ball groove is formed on the compression buffer arc block, and a buffer ball is mounted inside the ball groove.

[0009] This utility model provides a protective structure for a dual-output pressure transmitter. It offers the following advantages: The protective structure of this dual-output pressure transmitter adopts a modular, semi-casing design with an I-shaped cross-section. This design enhances resistance to deformation through a rigid sleeve structure and allows for quick assembly and disassembly via bolt-locked connecting plates, avoiding the high maintenance costs associated with welded or integrally molded housings. An integrated magnetic buffer system is located inside the sleeve. A magnetic repulsion damping layer is formed by a telescopic compression block with a convex telescopic groove and magnets of the same pole on a metal semi-circular rod. Upon impact, the reduced magnet spacing generates a reverse repulsive force that dissipates energy. This, combined with the spherical contact between the rubber buffer ball and the compression buffer arc block, disperses pressure, effectively solving the problems of rubber gasket aging and wear, and weld fatigue caused by high-frequency vibration. It also avoids zero-point drift caused by stress transmitted through the rigid housing. Through the synergistic effect of magnetic repulsion buffering, elastic rubber blocks, forced airflow cooling, modular assembly and disassembly, and a high-strength observation window, the durability, maintainability, and functionality of the protective structure are significantly improved.

[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0016] Please see Figure 1-3 In the field of industrial process control, dual-output pressure transmitters need to be exposed to mechanical shock, vibration and temperature changes for a long time. Traditional protective structures have the following key defects: rubber gaskets or spring mechanical buffers are prone to aging failure and friction wear; high-frequency vibration can easily cause fatigue fracture of the solder joints of the internal circuit board of the transmitter; although rigid housings are impact resistant, they will amplify the transmitted stress, causing zero drift of the sensor; welded or one-piece molded housings require complete replacement for repair, resulting in high downtime costs; missing or insufficiently strong observation windows (such as acrylic sheets) make real-time diagnosis impossible and they are easily cracked by flying debris. Therefore, this application protects the protective structure of a dual-output pressure transmitter. By movably fitting a pair of semi-circular sleeves 1 onto the outside of the transmitter, and by pressing the connecting fixing plates 2 on the outside of the semi-circular sleeves 1 against each other, multiple connecting fixing plates 2 are pressed and fixed by bolts. Simultaneously, the compression of the transmitter by the pair of semi-circular sleeves 1 provides sleeve protection. At the same time, the transmitter is cushioned by the shock absorber inside the semi-circular ring limiting block 3 on the inner side of the semi-circular sleeves 1. The magnetic force is transferred to the metal semi-circular rod 6 → multiple metal rods 7 → the telescopic magnet 8 on the telescopic compression block 4 through the telescopic magnet 8 inside the shock absorber, thereby achieving... The magnetic repulsion telescopic extrusion block 4 causes the telescopic extrusion block 4 to stably extend and retract along the inner side of the telescopic groove 5. The telescopic extrusion block 4 drives the extrusion buffer arc block 9 and the buffer ball 11 on it to perform flexible annular telescopic and flexible extrusion on the transmitter, so that there is a buffer layer on the outside of the transmitter. At the same time, the protective arc rubber block 14 makes flexible contact with the transmitter. The deformation of the protective arc rubber block 14 provides buffering, and the heat dissipation holes 15 on the protective arc rubber block 14 dissipate heat while preventing excessive extrusion and damage. In summary, a pair of I-shaped semi-casings 1 cover the transmitter's outer side and are bolted together by multiple connecting plates 2 along the edges to form a rigid protective sleeve. Multiple semi-circular limiting blocks 3 are installed inside the sleeve to mount magnetic dampers. A telescopic compression block 4 is movably embedded in the telescopic groove 5 of the limiting block through a convex profile. A compression buffer arc block 9 with a rubber buffer ball 11 is mounted on it. A metal semi-circular rod 6 is fixed to the limiting block by a metal rod 7, forming a magnetic repulsion damping layer with the telescopic magnet block 8 on the telescopic compression block 4 and the corresponding magnet. During impact, the magnet spacing decreases, generating a reverse repulsive force to dissipate energy. The buffer ball 11 disperses pressure through spherical contact to adapt to unevenness in the outer casing. An auxiliary elastic layer is provided by a protective arc rubber block 14, whose deformation absorbs high-frequency vibrations. The rubber block and the sleeve's heat dissipation holes... The 15-fold alignment forms an air duct, while the filter screen is sandwiched between the protective arc rubber block 14 and the half-tube sleeve 1 to prevent dust from entering the heat dissipation hole 15. The vortex cooler integrated inside the sleeve is connected to an external air pump through an air inlet pipe to guide the low-temperature airflow into the heat dissipation air duct and is controlled by a stable sensor to start and stop the temperature control. The I-shaped sleeve cross-section enhances the resistance to deformation, the convex expansion groove 5 mechanically locks the buffer component to prevent it from falling out, and the top inserted glass groove 12 installs the protective glass 13 to achieve status visualization. The modular half-tube sleeve design supports quick disassembly and maintenance. Finally, the magnetic repulsion buffer avoids mechanical wear (the rubber ball and the rubber block constitute secondary protection), the vortex cooling forces airflow circulation to break through the heat dissipation bottleneck of the closed space, and the filter screen balances dust prevention and air permeability in the heat dissipation hole 15 to achieve long-term stable operation.
