Low temperature submersible pump liquid level gauge

Abstract

This utility model discloses a cryogenic submersible pump level gauge, applied in the field of submersible pumps. This utility model utilizes a first rotating cylinder to move a connecting rod, causing the locking connector to move. The moving locking connector disengages from the locking hole, allowing the level gauge to be removed. During installation, the level gauge is inserted into the water tank housing, where the locking connector, under the action of a spring, engages with the locking hole, securing it. This facilitates assembly and disassembly, reducing workload and improving efficiency. Furthermore, by rotating a second rotating cylinder, the inner wall of the second rotating cylinder relaxes, compressing an elastic fixing rod. This relaxes the elastic fixing rod, compressing a sensing guide rod. After moving the sensing guide rod to the desired position, the second rotating cylinder is tightened, causing the elastic fixing rod to press against the sensing guide rod, securing it. This allows for adjustment of the sensing guide rod's position, reducing operating costs and improving practicality and applicability.

Description

Technical Field

[0001] This utility model relates to the field of submersible pumps, and in particular to a cryogenic submersible pump level gauge. Background Technology

[0002] Currently, Chinese utility model patent CN216695190U discloses a float level gauge, relating to the technical field of level detection equipment. This float level gauge includes a float, a sensing rod, a flange, a signal converter, and an anti-tilt mechanism. The anti-tilt mechanism includes a connecting plate and an anti-tilt component. The connecting plate, sensing rod, and flange are coaxial, with the connecting plate welded to the lower side of the flange. The anti-tilt component has a fixedly connected connecting part and an anti-tilt part, which are perpendicular to each other. The upper side of the connecting part abuts against the lower side of the connecting plate, and the anti-tilt part abuts against the upper part of the sensing rod. The connecting part is detachably connected to the connecting plate. Before installing the float level gauge in a predetermined position via the flange, the anti-tilt component can be connected to the connecting plate. At this time, the upper side of the connecting part abuts against the lower side of the connecting plate, and the anti-tilt part abuts against the upper part of the sensing rod, thereby limiting the tilt of the sensing rod and keeping it vertical, ensuring the accuracy of the detection results.

[0003] Existing level gauges are inconvenient to install and disassemble. Generally, level gauges are installed on the tank shell via flanges or threads. During installation, tools are required for disassembly and assembly, which is cumbersome, increases workload, and reduces work efficiency. Furthermore, the position of the sensing guide rod cannot be adjusted, as the length of the sensing guide rod is usually fixed. This means that the level gauge can only be used for tanks of the same depth. If it is necessary to measure tanks of different depths, a corresponding level gauge must be replaced, increasing the cost of use and reducing practicality and applicability. To solve the above problems, we propose a cryogenic submersible pump level gauge. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cryogenic submersible pump level gauge includes a water tank shell, a cover plate is provided on the top of the water tank shell, a first fixed cylinder is bolted to the bottom of the cover plate and the first fixed cylinder is slidably sleeved with the surface of the water tank shell, a first rotating cylinder is rotatably sleeved with the surface of the first fixed cylinder, a connecting rod is hinged to the inner wall of the first rotating cylinder, a snap-fit ​​connector is hinged to the other end of the connecting rod, a spring is provided between the snap-fit ​​connector and the inner wall of the first fixed cylinder, a snap-fit ​​hole is opened on the surface of the water tank shell and snaps with the snap-fit ​​connector, a sensing guide rod is slidably sleeved with the inner wall of the cover plate, a second fixed cylinder is bolted to the surface of the cover plate and the second fixed cylinder is slidably sleeved with the surface of the sensing guide rod, an elastic fixing rod is bolted to the surface of the fixed cylinder and the elastic fixing rod is located inside the second fixed cylinder, a digital meter is installed on the top of the sensing guide rod, and a float is slidably sleeved with the surface of the sensor guide rod.

[0006] By adopting the above technical solution, rotating the first rotating cylinder causes the connecting rod to move the snap-fit ​​connector. The snap-fit ​​connector moves, disengaging from the snap-fit ​​hole, allowing the level gauge to be removed. During installation, the level gauge is inserted into the water tank housing, and the snap-fit ​​connector, under the action of a spring, snaps into the snap-fit ​​hole, fixing it in place. This facilitates installation and removal, reduces workload, and improves efficiency. Rotating the second rotating cylinder relaxes the inner wall, squeezing the elastic fixing rod, which in turn relaxes the elastic fixing rod, squeezing the sensing guide rod. After moving the sensing guide rod to the desired position, tightening the second rotating cylinder causes the elastic fixing rod to press against the sensing guide rod, fixing it in place. This achieves the purpose of adjusting the position of the sensing guide rod, reducing operating costs and improving practicality and applicability.

[0007] The present invention is further configured such that anti-slip textures are provided on the surfaces of both the first rotating cylinder and the second rotating cylinder.

[0008] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0009] The present invention is further configured such that: a positioning rod is bolted to the bottom of the cover plate, and the positioning rod is slidably sleeved with the inner wall of the water tank shell.

[0010] By adopting the above technical solution, the positioning rod is set to facilitate the positioning of the first fixed cylinder, prevent displacement, and facilitate installation.

[0011] The present invention is further configured such that the surface of the sensing guide rod is printed with scale lines.

[0012] By adopting the above technical solution, the position of the sensing guide rod can be easily adjusted by setting scale lines.

[0013] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0014] By adopting the above technical solution, one end of the snap-fit ​​connector is wedge-shaped, which facilitates installation.

[0015] The present invention is further configured such that a rubber pad is bolted to one end of the elastic fixing rod.

[0016] By adopting the above technical solution, rubber pads are installed to prevent slippage and ensure stability.

[0017] The present invention is further configured such that a limiting block is bolted to the bottom of the sensing guide rod.

[0018] By adopting the above technical solution, a limiting plate is set to prevent the pontoon from slipping and ensure stability.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model uses the first rotating cylinder to rotate the connecting rod to move the snap-fit ​​connector. The snap-fit ​​connector moves and disengages from the snap-fit ​​hole, allowing the level gauge to be removed. During installation, the level gauge is inserted into the water tank housing, and the snap-fit ​​connector engages with the snap-fit ​​hole under the action of the spring, thus fixing it in place. This achieves the purpose of facilitating installation and disassembly, reducing workload, and improving the efficiency of installation and disassembly.

[0021] 2. This utility model achieves the purpose of adjusting the position of the sensor guide rod by rotating the second rotating cylinder to relax the inner wall of the second rotating cylinder and squeeze the elastic fixing rod, which in turn relaxes the elastic fixing rod and squeezes the sensor guide rod. After the sensor guide rod is moved to the required position, the second rotating cylinder is tightened to press the elastic fixing rod against the sensor guide rod and fix it, thereby reducing the cost of use and improving practicality and applicability.

A snap-fit ​​hole 8 is opened on the surface of the water tank housing 1, and the snap-fit ​​hole 8 snaps with the snap-fit ​​connector 6. By rotating the first rotating cylinder 4, the connecting rod 5 drives the snap-fit ​​connector 6 to move. The movement of the snap-fit ​​connector 6 disengages the snap-fit ​​connector 6 from the snap-fit ​​hole 8, allowing the level gauge to be removed. During installation, the level gauge is inserted into the water tank housing 1, and the snap-fit ​​connector 6 snaps with the snap-fit ​​hole 8 under the action of the spring 7, thus fixing it. This achieves the purpose of easy installation and disassembly, reduces workload, and improves the efficiency of installation and disassembly.

[0032] refer to Figure 4 The surfaces of the first rotating cylinder 4 and the second rotating cylinder 19 are both provided with anti-slip textures 14. By providing anti-slip textures 14, the hands are prevented from slipping and the operation is made easier.

[0033] refer to Figure 4 and Figure 5 A positioning rod 15 is bolted to the bottom of the cover plate 2, and the positioning rod 15 is slidably sleeved with the inner wall of the water tank shell 1. By setting the positioning rod 15, it is easy to position the first fixed cylinder 3, prevent displacement, and facilitate installation.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 A sensing guide rod 9 is slidably sleeved on the inner wall of the cover plate 2. A second fixing cylinder 10 is bolted to the surface of the cover plate 2, and the second fixing cylinder 10 is slidably sleeved with the surface of the sensing guide rod 9.

A float ball 13 is slidably sleeved on the surface of the sensing guide rod. By rotating the second rotating cylinder 19, the inner wall of the second rotating cylinder 19 is relaxed to press the elastic fixing rod 11, and the elastic fixing rod 11 is relaxed to press the sensing guide rod 9. Then, after the sensing guide rod 9 is moved to the required position, the second rotating cylinder 19 is tightened to press the elastic fixing rod 11 against the sensing guide rod 9 and fix it. This achieves the purpose of adjusting the position of the sensing guide rod 9, reducing the cost of use and improving practicality and applicability.

[0037] refer to Figure 1 and Figure 2 The surface of the sensing guide rod 9 is printed with scale lines 16, which facilitates the adjustment of the position of the sensing guide rod 9.

[0038] refer to Figure 2 , Figure 3 and Figure 6 One end of the elastic fixing rod 11 is bolted with a rubber pad 18. By setting the rubber pad 18, slippage is prevented and stability is ensured.

[0040] Brief description of the usage process: Rotate the first rotating cylinder 4. The rotation of the first rotating cylinder 4 drives the connecting rod 5 to move. The movement of the connecting rod 5 drives the snap-fit ​​connector 6 to move. The snap-fit ​​connector 6 disengages from the snap-fit ​​hole 8, allowing the level gauge to be removed. During installation, insert the level gauge into the water tank housing 1. The snap-fit ​​connector 6 engages with the snap-fit ​​hole 8 under the action of the spring 7, fixing it in place and facilitating installation and removal. Rotate the second rotating cylinder 19. The second rotating cylinder 19 moves longitudinally. The longitudinal movement of the second rotating cylinder 19 relaxes the inner wall of the second rotating cylinder 19, which then presses against the elastic fixing rod 11. The elastic fixing rod 11 relaxes, which then presses against the sensing guide rod 9. After moving the sensing guide rod 9 to the desired position, tighten the second rotating cylinder 19, which presses the elastic fixing rod 11 against the sensing guide rod 9, fixing it in place and thus adjusting the position of the sensing guide rod 9.
