Description

Technical Field

[0001] This utility model belongs to the technical field of float level gauges, specifically relating to a float for a float level gauge. Background Technology

[0002] The float is the core component of a float level gauge, typically a hollow cylinder or similar structure with a certain volume and weight. Immersed in the liquid being measured, it senses changes in liquid level through buoyancy, making it the key component for level measurement. The float's displacement is converted into an electrical signal output by a conversion mechanism. This signal can be further recorded or transmitted to the control system, enabling real-time monitoring of the liquid level. Due to its simple structure, ease of operation, and good stability, float level gauges are widely used in various applications requiring liquid level measurement.

[0003] Chinese Patent Publication No. CN218994487U discloses a float level gauge, including a cylinder body. A transmission and display device is installed inside the cylinder body. A clamp rotation device is installed on the lower wall of the cylinder body, and a float telescopic device is installed on the side wall of the cylinder body. When fixing at different positions, the motor inside the motor box is activated. The rotation of the motor drive end causes the fixing block to swing, thereby rotating the clamp box to the position requiring clamping and fixing. At this time, the cylinder inside the clamp box is activated. The T-shaped telescopic end of the cylinder drives a pair of support rods to move, thereby causing a pair of clamping plates to clamp. Thus, the gauge is fixed at the required position using clamps, solving the problem of inconvenient fixing when there is no clamping device at different positions.

[0004] In practical use, this utility model mainly relies on floats to accurately measure the liquid level. However, the volume of existing float level gauges is often fixed, which limits them to effectively measuring media with fixed density or viscosity. When faced with liquids of different densities or viscosities, the original floats may not be able to maintain accurate measurement due to changes in buoyancy. Therefore, in order to meet the measurement needs of different liquids, it is often necessary to replace them with floats of suitable volume. This requirement not only increases the complexity of operation but also significantly reduces the flexibility and applicability of float level gauges in float use, making them somewhat limited when facing diverse measurement tasks.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a float for a float level gauge, comprising:

[0030] Converter 1, torque tube assembly 2, and connecting assembly 3;

[0031] The pontoon body 4 is located at the bottom of the connecting component 3. The bottom of the pontoon body 4 is provided with an extension tube 5. The bottom of the inner wall of the pontoon body 4 is provided with an installation ring 6. The bottom of the installation ring 6 is located inside the extension tube 5.

[0032] A fixing ring 7 is provided on the outside of the extension tube 5. An abutting ring 8 is provided on the outside of the extension tube 5 at the upper end of the fixing ring 7. Multiple positioning holes are provided through the side wall of the extension tube 5 on one side of the abutting ring 8. Each of the multiple positioning holes is provided with a matching abutting rod 9.

[0033] An adjustment groove is provided at the bottom of the extension cylinder 5. An adjustment shaft 10 is rotatably connected inside the adjustment groove. An adjustment wheel 11 is provided at the upper end of the adjustment shaft 10. The bottom end of the adjustment shaft 10 passes through the adjustment groove and extends to the outside. Multiple mounting grooves are provided through the outside of the adjustment groove. Each of the multiple mounting grooves is provided with a matching extension plate 12.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, the outer side of the mounting ring 6 has multiple limiting holes 13 that are adapted to the abutment rods 9, and one end of each abutment rod 9 is located in one of the multiple limiting holes 13.

[0035] Through its design, by opening multiple limiting holes 13 on the outside of the mounting ring 6, and cooperating with multiple abutment rods 9 inside the extension tube 5, the position of the extension tube 5 can be flexibly adjusted and its position limited, thereby flexibly adjusting the volume of the float of the float level gauge, enabling it to accurately measure the liquid level of liquids with different densities or different viscosities.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, one end of each of the multiple abutting rods 9 is hemispherical and abuts against the inner wall of the abutting ring 8. The upper end of the inner wall of the abutting ring 8 is inclined. The abutting rods 9 with hemispherical ends and the abutting ring 8 with inclined upper ends can better push the abutting rods 9 to move, so that the abutting rods 9 can enter the limiting hole 13 and limit the position of the mounting ring 6.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, the upper end of the fixed ring 7 is provided with multiple guide rods 14, the upper ends of which all pass through the abutment ring 8 and extend to the outside. Compression springs 15 are sleeved on the outer sides of each guide rod 14, with both ends of the compression springs 15 respectively located on one side of the fixed ring 7 and the abutment ring 8. The multiple guide rods 14 restrict the vertical movement of the abutment ring 8, preventing it from shifting position, while the multiple compression springs 15 ensure that the abutment ring 8 remains on one side of the multiple abutment rods 9.

[0038] Specifically, such as Figure 2 and Figure 4 As shown, each of the multiple positioning holes has a limiting groove, and each of the multiple limiting grooves has a limiting ring 16. The multiple limiting rings 16 are respectively located on the outside of the multiple abutment rods 9. Each of the multiple abutment rods 9 is fitted with a limiting spring 17. The two ends of the limiting spring 17 are respectively located on one side of the limiting ring 16 and the limiting groove. The multiple limiting rings 16, together with the multiple limiting springs 17, can restrict the position of the multiple abutment rods 9. When the abutment ring 8 moves downward, the multiple abutment rods 9 can disengage from the limiting hole 13, thereby allowing the mounting ring 6 to move.

[0039] Specifically, such as Figure 3 As shown, the upper end of the adjusting wheel 11 is rotatably connected to multiple connecting rods 18, and the other ends of the multiple connecting rods 18 are respectively set at one end of multiple extension plates 12. When the adjusting wheel 11 rotates, the multiple connecting rods 18 can drive the multiple extension plates 12 to move, thereby adjusting the bottom area of ​​the float of the float level gauge to adapt to liquids of different densities or different viscosities.

[0040] Specifically, such as Figure 2 and Figure 5As shown, a rectangular groove is provided on one side of the upper end of multiple mounting slots. Multiple return springs 19 are provided in multiple rectangular grooves. The bottom end of multiple return springs 19 located on the same side is provided with a locking plate 20 that is adapted to the rectangular groove. The bottom end of multiple locking plates 20 is set in an arc shape. Multiple locking grooves adapted to the locking plates 20 are provided on the upper end of multiple extension plates 12. The bottom end of multiple locking plates 20 is located in multiple locking grooves. The multiple arc-shaped locking plates 20 and the multiple locking grooves on the upper end of multiple extension plates 12, together with the return springs 19 in multiple rectangular grooves, can limit the position of extension plates 12, prevent its position from shifting during use, and ensure the accuracy of the float level gauge in measuring the liquid level.

[0041] See Figure 1-5 When using a float level gauge to measure the liquid level of liquids with different densities or viscosities, the volume of the float needs to be adjusted according to the density or viscosity of the liquid. First, the contact ring 8 needs to be moved downwards, and multiple contact rods 9 can move outwards, disengaging from the limiting hole 13, so that the mounting ring 6 and the float body 4 can move, thereby adjusting the volume of the float. Then, the contact ring 8 is released, and the contact ring 8 will move upwards under the action of multiple compression springs 15. The contact ring 8 can push multiple contact rods 9 to move, so that the multiple contact rods 9 move into multiple limiting holes 13 respectively, thereby limiting the position of the mounting ring 6. When it is necessary to adjust the bottom area of ​​the float, the adjusting shaft 10 needs to be rotated. The adjusting shaft 10 will drive the adjusting wheel 11 to rotate, and the adjusting wheel 11 will drive multiple extension plates 12 to move through multiple connecting rods 18, thereby adjusting the bottom area of ​​the float, so that it can accurately measure the liquid level of liquids with different densities or viscosities.

[0046] A fixing ring 7 is provided on the outside of the extension tube 5. An abutting ring 8 is provided on the outside of the extension tube 5 at the upper end of the fixing ring 7. Multiple positioning holes are provided through the side wall of the extension tube 5 on one side of the abutting ring 8.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, a vent 21 is provided on one side of the upper end of the float body 4, and a matching plug 22 is provided inside the vent 21. A sealing ring 23 is provided on the outer side of the bottom end of the mounting ring 6, and the sealing ring 23 abuts against the inner wall of the extension tube 5.

[0049] Through its design, the volume of the float can be effectively adjusted by the vent 21 set at the upper end of the float body 4. The plug 22 inside the vent 21, together with the sealing ring 23 on the outer side of the bottom end of the mounting ring 6, can ensure the sealing of the float of the float level gauge, thereby effectively preventing gas leakage and enabling the float to measure the liquid level stably and accurately in various environments.
