Description

Technical Field

[0001] This utility model relates to the field of industrial production and process control technology, and more specifically, it relates to a float-type liquid level gauge. Background Technology

[0002] In industrial production and process control, accurate liquid level monitoring is crucial. Float level gauges are widely used in various storage tanks and containers due to their simple and reliable working principle. However, in actual use, the maintenance and replacement of the reading gauge is a common and necessary operation. Under the current technology, the reading gauge of the float level gauge is usually fixed to the torque tube by multiple sets of bolts. Although this design ensures the stability of the connection, it brings many inconveniences during maintenance and replacement. When it is necessary to disassemble the electronic meter head, the staff must use wrenches and other tools to unscrew multiple sets of bolts one by one. However, the installation position of these bolts is usually close to the flange on the torque tube. The presence of the flange seriously hinders the staff's operating space for wrenches and other tools, making the disassembly process extremely difficult.

[0003] In today's world, where rapid response and efficient maintenance have become industry standards, this time-consuming and labor-intensive disassembly method can no longer meet the needs of modern industry. Operators working in confined spaces not only increase labor intensity but also prolong equipment downtime, directly impacting production efficiency. Furthermore, frequent bolt disassembly and assembly can lead to thread wear, affecting connection reliability. In certain special environments, such as high-temperature, high-pressure, or corrosive environments, the need for rapid disassembly and installation of reading instruments is even more urgent, as prolonged exposure time may pose safety hazards to equipment and operators. Therefore, developing a new connection mechanism that enables quick and easy installation and disassembly of reading instruments can not only improve maintenance efficiency and reduce downtime but also enhance operational safety, meeting the high demands of modern industry for equipment flexibility and maintainability.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a float-type level gauge, which has the following advantages:

[0017] 1. Benefits of the Fixing Mechanism: The fixing mechanism, through components such as the insertion tube, snap-fit ​​sleeve, arc-shaped rod, and locking block, enables rapid connection and disassembly of the reading gauge and the torque tube, greatly improving maintenance efficiency. The limiting groove on the insertion tube cooperates with the limiting strip inside the snap-fit ​​sleeve to ensure the accuracy of the installation position. The arc-shaped rod can move flexibly under the action of the push plate and compression spring, allowing the locking block to accurately engage in the slot of the insertion tube, achieving a stable connection. The design of the locking sleeve and locking block further enhances the reliability of the connection and prevents accidental dislodgement. The design of the sliding bar and sliding groove ensures the smooth movement of the arc-shaped rod, improving the smoothness of operation. The automatic connection design of the terminal socket and terminal plug simplifies the electrical connection process and improves installation efficiency. This multi-protection design not only enables rapid installation and disassembly but also ensures the stability and reliability of the connection, greatly improving the service life and maintenance efficiency of the level gauge.

[0018] 2. Beneficial Effects of the Limiting Mechanism: The limiting mechanism consists of a limiting sleeve, a clearance groove, a mounting sleeve, a vertical rod, and a stop block. It provides additional safety protection for the fixing mechanism. The rotating design of the limiting sleeve allows the operator to flexibly control the locking state. When the stop block is in the clearance groove, the locking sleeve can slide freely, facilitating quick installation and disassembly. When locking is required, rotating the limiting sleeve causes the stop block to leave the clearance groove, effectively preventing the locking sleeve from sliding and preventing the reading gauge from accidentally falling off. The design of the mounting sleeve and vertical rod ensures the precise positioning of the stop block, while the setting of the spring provides appropriate resistance, making the operation smoother. The design of multiple push springs keeps the limiting sleeve fixed in the unlocked state, avoiding the trouble of frequent adjustments. This design not only increases the safety of the fixing mechanism but also improves the convenience and reliability of operation, enabling the level gauge to maintain a stable connection state in various working environments.

[0019] 3. Beneficial Effects of the Sealing Mechanism: The sealing mechanism consists of components such as a sealing gasket, sealing tube, sealing strip, bellows, and top spring, providing multiple layers of sealing protection. The sealing gasket and sealing tube are in direct contact with the insertion tube, forming an initial seal, while multiple sets of sealing strips further enhance the sealing effect, effectively preventing liquid or gas leakage. The bellows design allows the sealing structure to have a certain degree of elastic deformation, adapting to different installation conditions and working environments, ensuring the reliability of the seal. The multiple sets of top springs ensure continuous sealing pressure, maintaining a good sealing effect even under vibration or temperature changes. This multi-seal design not only improves the sealing performance of the level gauge but also enhances its adaptability to various harsh environments, extends the service life of the equipment, reduces maintenance frequency, and improves overall work efficiency and reliability.

The limiting sleeve 14 is rotatably mounted on the bottom end of the locking sleeve 11. Multiple clearance grooves 15 are provided on the limiting sleeve 14. The mounting sleeve 16 is rotatably mounted on the bottom end of the snap-fit ​​sleeve 5. Multiple vertical rods 17 are provided on the mounting sleeve 16.

[0031] A terminal socket 19 is installed on one side of the torque tube 2. The terminal socket 19 is located inside the snap-fit ​​sleeve 5. A terminal plug 20 is installed on the rear side of the reading meter 3. The terminal plug 20 is located inside the insertion tube 4. When the insertion tube 4 is inserted into the snap-fit ​​sleeve 5, the two are automatically connected.

[0032] The outer wall of the insertion tube 4 has a limiting groove 21, and multiple sets of limiting grooves 21 are provided. The inner wall of the snap-fit ​​sleeve 5 is provided with a limiting strip 22, and multiple sets of limiting strips 22 are provided and slidably connected with multiple sets of limiting grooves 21. The outer wall of the insertion tube 4 has multiple sets of limiting grooves 21, and the inner wall of the snap-fit ​​sleeve 5 has multiple sets of limiting strips 22. The two are slidably connected to ensure the precise alignment of the insertion tube 4 and the snap-fit ​​sleeve 5.

[0033] Multiple sets of arc-shaped rods 7 are provided with slide bars 23 on their outer walls, and multiple sets of sliding holes 6 are provided with sliding grooves 24 on their inner sides. The multiple sets of sliding grooves 24 are slidably connected to the multiple sets of slide bars 23 respectively.

The outer wall of the arc-shaped rods 7 has slide bars 23, and the inner side of the sliding holes 6 has sliding grooves 24, and the two are slidably connected.

[0034] The mounting sleeve 16 is equipped with a retaining spring 27. Multiple sets of retaining springs 27 are provided and are respectively located on the outside of multiple sets of vertical rods 17, providing appropriate resistance.

[0035] Push springs 28 are provided between the outer wall of the locking sleeve 11 and the limiting sleeve 14, and multiple sets of push springs 28 are provided.

[0036] In this embodiment, when the reading meter 3 needs to be installed, the limiting groove 21 on the outer wall of the insertion tube 4 is aligned with the limiting strip 22 on the inner wall of the snap-fit ​​sleeve 5, and the insertion tube 4 is inserted into the snap-fit ​​sleeve 5, so that the terminal insertion hole 19 and the terminal plug 20 are connected. The top of the insertion rod pushes the push plate 8 to abut against multiple sets of push plates 8, and at the same time squeezes the top spring 33 and the compression spring 26, so that the arc-shaped rod 7 moves outward under the action of the push plate 8, thereby pushing multiple sets of snap-fit ​​blocks 9 into the snap-fit ​​groove 10 on the outer wall of the insertion tube 4, and at the same time, the top of the insertion tube 4 contacts the sealing mechanism to seal between the insertion tube 4 and the snap-fit ​​sleeve 5. Then, the sliding locking sleeve 11 is slid to allow the locking block 12 to enter the arc-shaped rod 7. The lock hole 13 further secures the connection. When the lock sleeve 11 slides, the support rod and the limiting block are located in the relief groove 15. Under normal conditions, the lock sleeve 11 is allowed to slide freely. When locking is required, the limiting sleeve 14 is rotated to make the stop 18 leave the relief groove 15 and prevent the lock sleeve 11 from sliding. This design increases the safety of the fixing mechanism and prevents the reading meter 3 from accidentally falling off. When in contact, the limiting sleeve 14 is rotated to make multiple sets of stop blocks 18 move to the round end of the relief groove 15 and pass through. At this time, multiple sets of push springs 28 are squeezed. Then, the vertical rod 17 is moved to the flat end of the relief groove 15 by the push of multiple sets of abutment springs 27, so that the limiting sleeve 14 remains fixed in the unlocked state.

[0037] Please see Figure 4 As one implementation of the sealing mechanism: a sealing mechanism is provided inside the snap-fit ​​sleeve 5. The sealing mechanism includes a sealing gasket 29, a sealing tube 30, a sealing strip 31, a bellows tube 32, and a top spring 33. The sealing gasket 29 is installed on the bottom surface of the push plate 8, the sealing tube 30 is installed on the bottom surface of the sealing gasket 29, multiple sets of sealing strips 31 are installed on the outer wall of the sealing tube 30, the two ends of the bellows tube 32 are respectively connected to the push plate 8 and the snap-fit ​​sleeve 5, and multiple sets of top springs 33 are provided with their two ends respectively connected to the push plate 8 and the snap-fit ​​sleeve 5. These components work together to form a multi-layer seal.

[0038] More specifically, when the insertion tube 4 is inserted into the snap-fit ​​sleeve 5, the sealing gasket 29 and the sealing tube 30 come into contact with the insertion tube 4 to form a preliminary seal. Multiple sets of sealing strips 31 further enhance the sealing effect. The design of the bellows 32 and the top spring 33 allows the sealing structure to have a certain degree of elastic deformation to adapt to different installation conditions while maintaining continuous sealing pressure. This multi-seal design ensures reliable sealing at the connection under various working conditions.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to install the reading meter 3, align the limiting groove 21 on the outer wall of the insertion tube 4 with the limiting strip 22 on the inner wall of the snap-fit ​​sleeve 5, and insert the insertion tube 4 into the snap-fit ​​sleeve 5, so that the terminal socket 19 and the terminal plug 20 are connected. The top of the insertion rod pushes the push plate 8 to abut against multiple sets of push plates 8, and at the same time squeezes the top spring 33 and the compression spring 26, so that the arc-shaped rod 7 moves outward under the action of the push plate 8, thereby pushing multiple sets of snap-fit ​​blocks 9 into the snap-fit ​​groove 10 on the outer wall of the insertion tube 4, and at the same time, so that the top of the insertion tube 4 contacts the sealing mechanism to seal between the insertion tube 4 and the snap-fit ​​sleeve 5. Then, slide the locking sleeve 11 to make the locking block 12 enter the arc-shaped groove 10. The locking hole 13 on the rod 7 is further fixedly connected. When the locking sleeve 11 slides, the support rod and the limiting block are located in the relief groove 15. Under normal conditions, the locking sleeve 11 is allowed to slide freely. When locking is required, the limiting sleeve 14 is rotated to make the stop 18 leave the relief groove 15 and prevent the locking sleeve 11 from sliding. This design increases the safety of the fixing mechanism and prevents the reading meter 3 from accidentally falling off. When in contact, the limiting sleeve 14 is rotated to make multiple sets of stop blocks 18 move to the round end of the relief groove 15 and pass through. At this time, multiple sets of push springs 28 are squeezed. Then, the vertical rod 17 is moved to the flat end of the relief groove 15 by the push of multiple sets of abutment springs 27, so that the limiting sleeve 14 remains fixed in the unlocked state.

[0040] When the insertion tube 4 is inserted into the snap-fit ​​sleeve 5, the sealing gasket 29 and the sealing tube 30 come into contact with the insertion tube 4 to form a preliminary seal. Multiple sets of sealing strips 31 further enhance the sealing effect. The design of the bellows 32 and the top spring 33 allows the sealing structure to have a certain degree of elastic deformation to adapt to different installation conditions while maintaining continuous sealing pressure. This multi-seal design ensures reliable sealing at the connection under various working conditions.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
