Description

Technical Field

[0001] This utility model relates to the field of liquid level measuring instrument technology, and more specifically, it relates to a novel digital liquid level measuring instrument. Background Technology

[0002] With the continuous improvement of industrial automation, liquid level measurement plays an increasingly important role in industrial production. In industries such as petroleum, chemical, and food, accurate and timely knowledge of liquid level data in storage tanks is of great significance for production management and safety control. However, the digital liquid level measuring instruments currently on the market have the problem of cumbersome installation in practical applications. They often need to be fixed with multiple bolts, which not only increases installation time but also makes it easy to fail to install properly due to improper operation, thus affecting measurement accuracy.

[0003] In harsh industrial environments, the sealing performance of liquid storage equipment is directly related to production safety and measurement accuracy. Existing liquid level measuring instruments generally use simple rubber gaskets as sealing elements. During long-term use, due to factors such as temperature changes and media corrosion, seal failure is prone to occur. This not only leads to liquid leakage, causing environmental pollution and safety hazards, but also affects the accuracy of measurement data, bringing many inconveniences to production management. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a novel digital liquid level measuring instrument to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A novel digital liquid level measuring instrument includes a storage tank. A measuring instrument body is mounted on the storage tank, and a digital display is connected to the bottom of the measuring instrument body. An installation mechanism is provided between the measuring instrument body and the storage tank. The installation mechanism includes a insert sleeve, a mounting sleeve, a movable groove, a locking block, a locking slot, a mounting plate, a push spring, a push plate, a rotating sleeve, an abutment block, a sealing gasket, a sealing ring, and a sealing groove. The insert sleeve is fixed to the bottom of the measuring instrument body, and the mounting sleeve is fixed to the bottom surface of the storage tank. Multiple sets of movable grooves are distributed on the outer wall of the mounting sleeve, and the locking blocks are movably arranged in multiple sets of movable grooves. Within the moving groove, multiple sets of slots are distributed on the outer wall of the insert sleeve, multiple sets of mounting plates are distributed on the outer wall of the mounting sleeve, multiple sets of push springs are respectively installed on the inner walls of the multiple sets of mounting plates, push plates are installed on the top of the multiple sets of push springs, a rotating sleeve is rotatably installed on the outer wall of the mounting sleeve, multiple sets of abutment blocks are distributed on the top surface of the rotating sleeve, the sealing gasket is disposed between the mounting sleeve and the insert sleeve, multiple sets of sealing rings are distributed on the outer wall of the insert rod, multiple sets of sealing grooves are distributed on the inner wall of the mounting sleeve, an unlocking sleeve is provided on the outer side of the mounting sleeve, the unlocking sleeve is disposed on the inner side of the multiple sets of slot blocks, and an inclined block is provided on the outer wall of the unlocking sleeve, with multiple sets of inclined blocks.

[0008] The present invention is further configured such that the outer wall of the insert sleeve is provided with positioning blocks, and multiple sets of positioning blocks are provided. The bottom end of the mounting sleeve is provided with positioning holes, and multiple sets of positioning holes are provided and adapted to multiple sets of positioning blocks. The cooperation between the positioning blocks and the positioning holes can ensure accurate alignment between the insert sleeve and the mounting sleeve, thereby improving the installation accuracy.

[0009] The present invention is further configured such that multiple sets of movable grooves are longitudinally arranged on the outer wall of the mounting sleeve, and multiple sets of locking blocks slide longitudinally within the multiple sets of movable grooves. The longitudinal arrangement of the movable grooves ensures the stability of the movement trajectory of the locking blocks and improves the locking reliability.

[0010] The present invention is further configured such that the connection between the abutment blocks and the rotating sleeve of the multiple sets is set in an arc shape. The arc-shaped connection design makes the rotation between the abutment blocks and the rotating sleeve smoother and reduces wear.

[0011] The present invention is further configured such that the sealing gasket is made of rubber, and the rubber sealing gasket has good elasticity and sealing performance, which can effectively prevent leakage.

[0012] The present invention is further provided that the bottom end of the multiple sets of card blocks and the outer side of the card slot are provided with rounded corners. The rounded corner design makes the cooperation between the card block and the card slot smoother and reduces the resistance during the locking process.

[0013] The present invention is further configured such that a limiting mechanism is provided on the outer side of the mounting sleeve. The limiting mechanism includes a limiting block, a limiting groove, a limiting sleeve, and a force spring. The limiting block has multiple sets that slide on the rotating sleeve, and the limiting groove has multiple sets that are distributed on the outer wall of the mounting sleeve. The limiting sleeve slides on the outer wall of the mounting sleeve, and the force spring has multiple sets with its two ends respectively connected to the limiting sleeve and the mounting sleeve. Through the multiple cooperation of the limiting mechanism, the position of the rotating sleeve is reliably limited, preventing accidental rotation.

[0014] The present invention is further configured such that a reset spring is installed at the top of each of the multiple sets of limiting blocks, and the multiple sets of reset springs are connected to the outer wall of the rotating sleeve. The setting of the reset spring ensures that the limiting blocks can automatically return to their original positions, thereby improving the operational convenience of the limiting mechanism.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a novel digital liquid level measuring instrument, which has the following beneficial effects:

[0017] 1. By setting an installation mechanism between the measuring instrument body and the storage tank, which includes the ingenious cooperation of components such as insert sleeve, mounting sleeve, movable groove, and locking block, the measuring instrument can be installed quickly. The cooperation between the positioning block and the positioning hole ensures accurate installation position. The push spring pushes the push plate to drive the locking block to engage with the locking groove to form a preliminary fixation. The rotating sleeve drives the abutment block to push the locking block to achieve further locking. At the same time, with the multiple sealing structure of sealing gasket, sealing ring and sealing groove, the technical problems of cumbersome installation and insufficient sealing performance in the prior art are effectively solved.

[0018] 2. By setting an unlocking sleeve on the outside of the mounting sleeve and setting an inclined block on its outer wall, when disassembly is required, simply rotate the unlocking sleeve and use the inclined block to push the card block outward, so that the card block is disengaged from the slot, and the disassembly operation can be completed quickly. This avoids the problems of needing tools and being time-consuming and laborious in traditional disassembly methods, and greatly improves the efficiency of equipment maintenance and replacement.

[0019] 3. By setting a limiting mechanism including a limiting block, a limiting groove, a limiting sleeve, and a force spring on the outside of the mounting sleeve, and setting a return spring connected to the rotating sleeve at the top of the limiting block, a reliable limiting system is formed. When the rotating sleeve is locked, the limiting sleeve pushes the limiting block into the limiting groove under the action of the force spring, effectively preventing the rotating sleeve from rotating accidentally. When releasing the limit, simply push the limiting sleeve, and the return spring will automatically drive the limiting block out of the limiting groove. The operation is simple and convenient, significantly improving the safety and reliability of the equipment. Attached Figure Description

[0029] Please see Figures 1-5A novel digital liquid level measuring instrument includes a storage tank 1, a measuring instrument body 2 mounted on the storage tank 1, a digital display 3 connected to the bottom of the measuring instrument body 2, and an installation mechanism between the measuring instrument body 2 and the storage tank 1. The installation mechanism includes a sleeve 4, a mounting sleeve 5, a movable groove 6, a locking block 7, a locking groove 8, a mounting plate 9, a push spring 10, a push plate 11, a rotating sleeve 12, a contact block 13, a sealing gasket 14, a sealing ring 15, and a sealing groove 16. The sleeve 4 is fixed to the bottom of the measuring instrument body 2, the mounting sleeve 5 is fixed to the bottom surface of the storage tank 1, multiple sets of movable grooves 6 are distributed on the outer wall of the mounting sleeve 5, the locking block 7 is movably disposed within multiple sets of movable grooves 6, and multiple sets of locking grooves 8 are provided. Multiple sets of mounting plates 9 are distributed on the outer wall of the insert sleeve 4. Multiple sets of push springs 10 are respectively installed on the inner wall of the multiple sets of mounting plates 9. Push plates 11 are installed on the top of the multiple sets of push springs 10. Rotating sleeve 12 is rotatably installed on the outer wall of the mounting sleeve 5. Multiple sets of abutment blocks 13 are distributed on the top surface of the rotating sleeve 12. Sealing gasket 14 is placed between the mounting sleeve 5 and the insert sleeve 4. Multiple sets of sealing rings 15 are distributed on the outer wall of the insert rod. Multiple sets of sealing grooves 16 are distributed on the inner wall of the mounting sleeve 5. Unlocking sleeve 17 is provided on the outer side of the mounting sleeve 5. Unlocking sleeve 17 is placed on the inner side of the multiple sets of locking blocks 7. Inclined blocks 18 are provided on the outer wall of unlocking sleeve 17. Multiple sets of inclined blocks 18 are provided.

[0030] The outer wall of the insert 4 is provided with positioning blocks 19, and there are multiple sets of positioning blocks 19. The bottom end of the mounting sleeve 5 is provided with positioning holes 20, and there are multiple sets of positioning holes 20 that are adapted to multiple sets of positioning blocks 19. When the positioning blocks 19 are inserted into the positioning holes 20, a keyway fit structure is formed to prevent the insert 4 from rotating relative to the mounting sleeve 5.

[0031] Multiple sets of movable grooves 6 are longitudinally arranged on the outer wall of the mounting sleeve 5, and multiple sets of locking blocks 7 slide longitudinally within the multiple sets of movable grooves 6. The movable grooves 6 provide longitudinal guidance for the locking blocks 7, ensuring that the locking blocks 7 can only move along the preset trajectory, thereby improving the accuracy of locking.

[0032] The connection points between the multiple sets of abutment blocks 13 and the rotating sleeve 12 are all set in an arc shape. The arc-shaped connection surface causes the abutment blocks 13 to generate a progressive thrust as the rotating sleeve 12 rotates, thus realizing the smooth movement of the locking block 7.

[0033] The sealing gasket 14 is made of rubber. When the rubber sealing gasket 14 is under pressure, it will undergo elastic deformation, filling the tiny gaps in the contact surface and forming a reliable seal.

[0034] The bottom of the multiple sets of locking blocks 7 and the outer side of the locking groove 8 are all provided with rounded corners. The rounded corner design of the locking blocks 7 and the locking groove 8 can generate a guiding effect during the meshing process and reduce the locking resistance.

[0035] In this embodiment, when the measuring instrument body 2 needs to be installed, the sealing gasket 14 is placed on the top surface of the insert sleeve 4, the measuring instrument body 2 is inserted into the mounting sleeve 5 and extends into the storage tank 1, and then the insert sleeve 4 is inserted into the mounting sleeve 5. Multiple sets of positioning blocks 19 are positioned and inserted into the positioning holes 20. Multiple sets of push springs 10 push the push plate 11, and the multiple sets of push plates 11 push multiple sets of locking blocks 7 so that their bottom ends are engaged in the locking groove 8. Then, the rotating sleeve 12 is rotated, and multiple sets of abutting blocks 13 abut against and guide the bottom ends of the multiple sets of locking blocks 7, so that the multiple sets of abutting blocks 13 push the multiple sets of locking blocks 7 to slide longitudinally along the movable groove 6, thereby pushing the sealing ring 15 set at the top of the insert sleeve 4 to engage in the sealing groove 16, while simultaneously squeezing the sealing gasket 14 and the mounting sleeve. The sleeve 12 is sealed between the sleeve 5 and the insert sleeve 4. Then, the rotating sleeve 12 is limited by the limiting mechanism to complete the installation of the tester body. The tester body is electrically connected to the digital display 3 to measure the liquid level in the storage tank 1. The liquid level value is displayed by the digital display 3. When it is necessary to disassemble the tester body, the limiting mechanism is released from the restriction of the rotating sleeve 12. The rotating sleeve 12 drives the abutment block 13 to rotate, so that the multiple sets of abutment blocks 13 release the push of the multiple sets of locking blocks 7. Then, the unlocking sleeve 17 is rotated to drive the multiple sets of inclined blocks 18 to rotate. The multiple sets of inclined blocks 18 push the locking blocks 7 to move outward, so that the multiple sets of locking blocks 7 disengage from the slot 8 and release the locking of the insert sleeve 4. Then the insert sleeve 4 can be pulled out of the installation sleeve 5, and then the measuring instrument body 2 can be disassembled.

[0036] Please see Figure 5 As one implementation of the limiting mechanism: a limiting mechanism is provided on the outside of the mounting sleeve 5. The limiting mechanism includes a limiting block 21, a limiting groove 22, a limiting sleeve 23, and a force spring 24. The limiting block 21 is provided with multiple sets that slide on the rotating sleeve 12. The limiting groove 22 is provided with multiple sets that are distributed on the outer wall of the mounting sleeve 5. The limiting sleeve 23 slides on the outer wall of the mounting sleeve 5. The force spring 24 is provided with multiple sets and its two ends are respectively connected to the limiting sleeve 23 and the mounting sleeve 5.

[0037] Each of the multiple sets of limit blocks 21 is equipped with a return spring 25 at its top. The multiple sets of return springs 25 are connected to the outer wall of the rotating sleeve 12. The return spring 25 stores elastic potential energy under the action of tension. When the limit sleeve 23 is released, it automatically drives the limit block 21 to return to its original position.

[0038] More specifically, when it is necessary to restrict the position of the rotating sleeve 12, multiple sets of push springs 10 push the limiting sleeve 23 to abut against multiple sets of limiting blocks 21 and apply a pushing force, pushing the multiple sets of limiting blocks 21 to engage in the limiting groove 22, thus completing the restriction of the rotating sleeve 12. However, when it is necessary to release, the limiting sleeve 23 is pushed to release the abutment against the top of the multiple sets of limiting blocks 21, and multiple sets of reset springs 25 pull the multiple sets of limiting blocks 21 to move outward, so that the multiple sets of limiting blocks 21 disengage from the limiting groove 22, thus releasing the restriction of the rotating sleeve 12.

[0039] In summary, when the entire device is in use or operation, but the measuring instrument body 2 needs to be installed, the sealing gasket 14 is placed on the top surface of the insert sleeve 4, the measuring instrument body 2 is inserted into the mounting sleeve 5 and extends into the storage tank 1, and then the insert sleeve 4 is inserted into the mounting sleeve 5. Multiple sets of positioning blocks 19 are positioned and inserted into the positioning holes 20. Multiple sets of push springs 10 push the push plate 11, and the multiple sets of push plates 11 push multiple sets of locking blocks 7 so that their bottom ends are engaged in the locking groove 8. Then, the rotating sleeve 12 is rotated, and multiple sets of abutting blocks 13 abut against and guide the bottom ends of the multiple sets of locking blocks 7, causing the multiple sets of abutting blocks 13 to push the multiple sets of locking blocks 7 to slide longitudinally along the movable groove 6, thereby pushing the sealing ring 15 set at the top of the insert sleeve 4 to engage in the sealing groove 16, while simultaneously compressing the sealing gasket 14. The mounting sleeve 5 and the insert sleeve 4 are sealed, and then the rotating sleeve 12 is limited by the limiting mechanism to complete the installation of the tester body. The tester body is electrically connected to the digital display 3 to measure the liquid level in the storage tank 1 and the liquid level value is displayed by the digital display 3. When it is necessary to disassemble the tester body, the limiting mechanism is released from the restriction of the rotating sleeve 12. The rotating sleeve 12 drives the abutment block 13 to rotate, so that the multiple sets of abutment blocks 13 release the push of the multiple sets of locking blocks 7. Then, the unlocking sleeve 17 is rotated to drive the multiple sets of inclined blocks 18 to rotate. The multiple sets of inclined blocks 18 push the locking blocks 7 to move outward, so that the multiple sets of locking blocks 7 disengage from the slot 8 and release the locking of the insert sleeve 4. Then the insert sleeve 4 can be pulled out of the mounting sleeve 5, and then the measuring instrument body 2 can be disassembled.

[0040] However, when it is necessary to restrict the position of the rotating sleeve 12, multiple sets of push springs 10 push the limiting sleeve 23 to abut against multiple sets of limiting blocks 21 and apply a pushing force, pushing the multiple sets of limiting blocks 21 to engage in the limiting groove 22, thus completing the restriction of the rotating sleeve 12. However, when it is necessary to release, push the limiting sleeve 23 to release the abutment against the top of the multiple sets of limiting blocks 21, and pull the multiple sets of limiting blocks 21 outward by multiple sets of reset springs 25, so that the multiple sets of limiting blocks 21 disengage from the limiting groove 22, thereby releasing the restriction of the rotating sleeve 12.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. 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. The scope of this utility model is defined by the appended claims and their equivalents.
