Description

Technical Field

[0001] The utility model belongs to the field of electric power equipment, and in particular relates to an automatic instrument sealing device. Background Art

[0002] Automation instruments include several automation components, such as sensors, transmitters, and displays, and possess various functions, including measurement, display, recording, and control. They are both a subsystem of the automation system and an information machine, primarily responsible for converting information into other forms. Their primary functions include detecting, measuring, observing, and calculating various physical quantities, material compositions, and physical parameters, such as temperature, pressure, and flow, as well as performing automatic control, alarms, signal transmission, and data processing. As a crucial component of industrial automation systems, automation instruments, through their measurement, control, and data processing capabilities, play a key role in improving production efficiency, ensuring production safety, and enhancing product quality.

[0003] Automation instrument sealing devices are key equipment used to ensure good sealing during the operation of automation instruments. Automation instrument sealing devices are widely used in various industrial automation systems, especially in occasions with strict requirements on environmental conditions, such as chemical and pharmaceutical industries. These devices protect instruments from corrosive gases or liquids, ensuring measurement accuracy and long-term stable operation of equipment.

[0004] Chinese patent CN112235988A discloses an automated instrument sealing device, which includes an internally hollow mounting box, in which an electric power meter is mounted and rotated, a first end cover is fixed to the front side of the mounting box using bolts, and a rectangular sealing ring is clamped between the mounting box and the first end cover to improve the sealing effect at the connection between the mounting box and the first end cover. The sealing effect is improved by providing a rectangular sealing ring. Since the first end cover is connected to the mounting box using bolts, it will become loose after long-term use, affecting the sealing performance of the device. On the other hand, when it is necessary to open the first end cover, tools must be used, and disassembly and assembly are cumbersome and inefficient.

[0005] Chinese patent CN210219243U discloses a sealing device for an automated instrument. The device requires pressing the automated instrument backward to the inside of a limiting ring, then sliding a movable rod inward, and then rotating a first bolt backward to secure the movable rod. The movable rod then acts as a limiter on the front of the automated instrument, preventing it from falling off the limiting ring, thereby achieving reinforcement. The sealing device is only suitable for automated instruments of specific shapes and has a narrow application range. If the bolts become loose, the movable rod loses its limiter function, resulting in poor fixing of the automated instrument and shaking, which can cause collisions and damage to internal components of the automated instrument. Furthermore, the sliding rod must be slid and the first bolt rotated, making the operation complex. Utility Model Content

When the end of the lever passes through the first limit block and moves between the two limit blocks, the end of the lever hits the first limit block. This is the first gear adjusted by the push rod. At this time, the distance between the first partition and the second partition is the adjustment distance of the first gear.

[0021] Furthermore, the driving member is a motor, for example, a bidirectional motor.

[0022] Furthermore, two support rods are fixed on the base plate, and the two support rods are rotatably connected to the first transmission shaft and the second transmission shaft respectively. The support rods provide stable support for the first transmission shaft and the second transmission shaft to prevent the first transmission shaft and the second transmission shaft from shaking.

[0024] (1) Start the motor, the power output end of the motor rotates clockwise, driving the first transmission shaft to rotate, the first transmission shaft drives the first transmission rod to rotate clockwise, and at the same time the first connecting shaft rotates clockwise, the first connecting shaft causes the first limiting shaft to move through the first limiting rod, and the first limiting shaft causes the first moving rod to slide horizontally on the inner surface of the sliding rod toward the direction close to the third moving rod. Due to the movement of the first moving rod, the second moving rod drives the first telescopic member to slide in the direction away from the second telescopic member.

[0025] The first connecting shaft causes the second transmission rod to rotate in the forward direction, the second transmission rod causes the second limiting rod to move via the second connecting shaft, the second limiting rod drives the connecting block to move, the connecting block causes the third moving rod to slide horizontally on the inner surface of the sliding rod in a direction close to the first moving rod, the third moving rod drives the second telescopic member to slide in a direction away from the first telescopic member, the first telescopic member and the second telescopic member slide towards each other, the limiting plate gradually withdraws from the cavity, the first telescopic member and the second telescopic member are opened, and the motor is paused;

A through groove is provided in the middle part of the shift rod 102. The depth direction of the through groove is consistent with the height direction of the shift rod 102. The width of the through groove is much larger than the diameter or equivalent diameter of the second limit shaft 22. The second limiting shaft 22 passes through the through slot upward, and one end of the driving rod 102 extends into the connecting groove of the first supporting plate 20 and is rotatably connected to the first fixed shaft 101, and the other end is rotatably connected to the second fixed shaft 103. The second fixed shaft 103 is fixed on the push rod 104. The end of the driving rod 102 is arc-shaped and has a groove that semi-surrounds the push rod 104. The push rod 104 is arranged between the second limiting shaft 22 and the limiting block 21. The width of the push rod 104 is less than the distance between the second limiting shaft 22 and the limiting block 21, so that the push rod 104 has a certain movable space between the second limiting shaft 22 and the limiting block 21, and pushes the push rod 104 toward the direction of the limiting block 21. One end of the driving rod 102 rotates around the second fixed shaft 103, and the second fixed shaft 103 brings One end of the shift rod 102 moves synchronously with the push rod 104, and the other end of the shift rod 102 rotates around the first fixed axis 101 while pushing the first support plate 20 close to the second partition plate 24, shortening the distance between the first partition plate 18 and the second partition plate 24. When the end of the shift rod 102 passes the first limit block and moves between the two limit blocks 21, the end of the shift rod 102 is against the first limit block. This is the first gear adjusted by the push rod 104. At this time, the distance between the first partition plate 18 and the second partition plate 24 is the adjustment distance of the first gear. Continue to push the push rod 104, and the shift rod 102 continues to push the first support plate 20 close to the second partition plate 24. The distance between the first partition plate 18 and the second partition plate 24 is further reduced. The end of the shift rod 102 passes After the second limit block is moved to the rear end of the second limit block, the end of the lever 102 is against the second limit block. This is the second gear adjusted by the push rod 104. At this time, the distance between the first partition 18 and the second partition 24 is the adjustment distance of the second gear. The limit block 21 is used to prevent the lever 102 from resetting. When the end of the lever 102 is at the front end of the first limit block, the distance between the first partition 18 and the second partition 24 is the maximum. First, since the limit block 21 is set on one side of the straight line where the first fixed axis 101 and the second limit axis 22 are located, when the end of the lever 102 is against the second limit block, the angle between the lever 102 and the first support plate 20 is less than 90 degrees. When the first spring 17 is in a compressed state, it gives thrust to the first support plate 20.The first support plate 20 then pushes the lever 102 so that the lever 102 is pressed against the second limit block. The fixing mechanism 10 preliminarily adjusts the distance between the first partition 18 and the second partition 24, thereby fixing automation instruments of different sizes.

[0059] A second support plate 25 and a second partition 24 sliding on the second bottom plate 142 are fixed on the second bottom plate 142. A plurality of second springs 23 are provided between the second support plate 25 and the second partition 24. For example, there can be two second springs 23. The extension and contraction direction of the second spring 23 is, for example, perpendicular to the second support plate 25. In specific applications, after the first telescopic member 9 and the second telescopic member 14 are closed, the first spring 17 and the second spring 23 are in a compressed state, and the automation instrument between the first partition 18 and the second partition 24 is fixed in the box formed by the first telescopic member 9 and the second telescopic member 14.

[0060] A guide rail 27 is fixed on the base plate 1 and passes through the base plate 1 in the length direction. The first moving rod 63, the third moving rod 133, the second bottom plate 142 and the first bottom plate 92 are all provided with through holes on the side where the first moving rod 63, the third moving rod 133, the second bottom plate 142 and the first bottom plate 92 are connected to the base plate 1. The guide rail 27 passes through the through holes of the first moving rod 63, the third moving rod 133, the second bottom plate 142 and the first bottom plate 92 in sequence. When the motor 2 is started, the first moving rod 63, the third moving rod 133, the second bottom plate 142 and the first bottom plate 92 slide linearly along the guide rail 27 on the base plate 1. The guide rail is provided to ensure that the first moving rod 63, the third moving rod 133, the first telescopic member 9 and the second telescopic member 14 slide on the same track, thereby preventing the first moving rod 63 or the third moving rod 133 or the first telescopic member 9 or the second telescopic member 14 from shifting during the sliding process, thereby affecting the use of the sealing device.

[0061] The driving member is a motor 2, which may be a bidirectional motor, for example.

[0062] Two support rods 11 are fixed on the base plate 1, and the two support rods 11 are rotatably connected to the first transmission shaft 3 and the second transmission shaft 31 respectively. The support rods 11 provide stable support for the first transmission shaft 3 and the second transmission shaft to prevent the first transmission shaft 3 and the second transmission shaft 31 from shaking.

[0063] The first telescopic member and the second telescopic member are provided with holes for the wires of the automation instrument to pass through.

[0064] The rotational connections described in this application all adopt conventional methods well known to those skilled in the art, such as bearing-type connections.

[0065] Application Examples

[0066] The working process of an automatic instrument sealing device of the utility model is as follows:

[0067] (1) Start the motor 2. The power output end of the motor 2 rotates clockwise, driving the first transmission shaft 3 to rotate. The first transmission shaft 3 drives the first transmission rod 4 to rotate clockwise. At the same time, the first connecting shaft 5 rotates clockwise. The first connecting shaft 5 causes the first limiting shaft 62 to move through the first limiting rod 61. The first limiting shaft 62 causes the first moving rod 63 to slide horizontally on the inner surface of the slide rod 16 toward the direction close to the third moving rod 133. Due to the movement of the first moving rod 63, the second moving rod 8 drives the first telescopic member 9 to slide in the direction away from the second telescopic member 14.

[0068] The first connecting shaft 5 causes the second transmission rod 12 to rotate in the forward direction. The second transmission rod 12 causes the second limiting rod 131 to move via the second connecting shaft 19. The second limiting rod 131 drives the connecting block 132 to move. The connecting block 132 causes the third moving rod 133 to slide horizontally on the inner surface of the slide rod 16 in a direction close to the first moving rod 63. The third moving rod 133 drives the second telescopic member 14 to slide in a direction away from the first telescopic member 9. The first telescopic member 9 and the second telescopic member 14 slide toward each other. The limiting plate 15 gradually withdraws from the cavity 95, opening the first telescopic member 9 and the second telescopic member 14, and the motor 2 pauses.

[0069] (2) Place the automation instrument between the first partition 18 and the second partition 24, start the motor 2 again, the power output end of the motor 2 rotates counterclockwise, driving the first transmission shaft 3 and the first transmission rod 4 to rotate counterclockwise, and at the same time the first connecting shaft 5 rotates counterclockwise, the first connecting shaft 5 causes the first limiting shaft 62 to return through the first limiting rod 61, the first limiting shaft 62 causes the first moving rod 63 to slide horizontally on the inner surface of the slide rod 16 in the direction away from the third moving rod 133, and the second moving rod 8 drives the first telescopic member 9 to slide in the direction close to the second telescopic member 14,

[0070] The first connecting shaft 5 causes the second transmission rod 12 to rotate in the opposite direction, and the second transmission rod 12 causes the second limiting rod 131 to move through the second connecting shaft 19, and the second limiting rod 131 drives the connecting block 132 to move, and the connecting block 132 causes the third moving rod 133 to slide horizontally on the inner surface of the slide rod 16 in the direction away from the first moving rod 63, and the third moving rod 133 drives the second telescopic member 14 to slide in the direction close to the first telescopic member 9, and the first telescopic member 9 and the second telescopic member 14 approach each other, and the limiting plate 15 gradually enters the cavity 95, and finally closes the first telescopic member 9 and the second telescopic member 14, and the motor 2 pauses, and the first partition 18 and the second partition 24 press against the automation instrument, and the first spring 17 and the second spring 23 are both in a compressed state (at this time, the end of the lever 102 is tightly against the front end of the first limiting block), fixing the automation instrument inside the first telescopic member 9 and the second telescopic member 14;

[0071] (3) When the first telescopic member 9 and the second telescopic member 14 are closed, the first partition 18 and the second partition 24 cannot abut against the automation instrument. In step (2), before inserting the automation instrument, the push rod 104 is pushed toward the limit block 21 to shorten the distance between the first partition 18 and the second partition 24. Then, the automation instrument is inserted and step (2) is performed. The first partition 18 and the second partition 24 abut against the automation instrument. The first spring 17 and the second spring 23 are in a compressed state, squeezing the end of the lever 102 tightly against the limit block 21 to prevent the lever 102 from resetting.

[0072] (4) When the automation instrument needs to be repaired or maintained, repeat step (1), open the first telescopic member 9 and the second telescopic member 14, and take out the automation instrument.

[0073] According to the present application, the first transmission shaft 3, the first transmission rod 4, the first connecting shaft 5, the second transmission rod 12, and the second connecting shaft 19 are driven by the motor to rotate clockwise and counterclockwise, so that the first telescopic part 9 and the second telescopic part 14 slide in different directions, thereby realizing the rapid fixed installation and disassembly of the automated instrument, reducing the installation and disassembly time, improving maintenance efficiency, and solving the problem that traditional sealing devices are difficult to disassemble and have a long maintenance time; at the same time, due to the arrangement of the first telescopic part 9, the second telescopic part 14, the push rod 104, the lever 102, the limit block 21, etc., the stability of the workpiece inside the sealing device is improved, and the service life of the workpiece inside the sealing device is extended.
