Description

Technical Field

[0001] The utility model relates to the technical field of float level gauges, in particular to a multifunctional float level gauge for a crude oil tanker. Background Art

[0002] At present, domestic crude oil contains a variety of complex components, with high viscosity, strong volatility, strong corrosiveness, and toxic and harmful substances. Crude oil is generally transported by crude oil tankers, and the oil products loaded in crude oil tankers are divided into pure crude oil and oil-water mixtures. The water content can be as high as 90%. When loading and unloading crude oil, the temperature is generally heated to the range of 30-90 degrees, accompanied by the generation of a large amount of steam and oil gas. Therefore, there are strict requirements on the manhole cover and liquid level gauge technology of crude oil tankers. However, the current float level gauge for crude oil tankers does not have the safety alarm reminder function of real-time display of crude oil liquid level during use, which makes it easy for crude oil tankers to overflow or leak oil when loading crude oil. This will not only endanger the safety of workers, but also cause pollution to the environment. Therefore, we propose a multi-functional float level gauge for crude oil tankers to solve the above problems. Utility Model Content

[0023] Example

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a multifunctional float level gauge for a crude oil tanker proposed in one embodiment of the present invention includes an upper transverse tube 1 and a lower transverse tube 3. A polyfluoroethane gasket 17 is fixed to one end of the upper transverse tube 1. The polyfluoroethane gasket 17 can be used to seal and protect the upper transverse tube 1 when it is installed. Protective sleeves 18 are fixed on both sides of the upper transverse tube 1, which can seal and protect both ends of the drive shaft where the polyfluoroethane roller is installed. The upper transverse tube 1 and the lower transverse tube 3 are connected and fixed through a connecting tube 2. A liquid level plate 4 fixed to the surface of the upper transverse tube 1 is provided on one side of the connecting tube 2. A float end 5 is installed on the upper transverse tube 1. A sealing cap flange 6 is installed on the surface of the float end 5. A trigger mechanism 7 and an alarm mechanism 8 are provided on the surface of the lower transverse tube 3.

[0025] like Figure 2 As shown, in some embodiments, a steam baffle 9 is provided on one side of the liquid level plate 4 and is clamped on the upper cross tube 1. The steam baffle 9 is fixed to the surface of the upper cross tube 1 by a disassembly column 10. When in use, a steam plug is also installed on the lower cross tube 3, and the plug is fixed to the lower cross tube 3 with bolts and can be disassembled. Therefore, the steam baffle 9 and the steam plug solve the problem of steam and oil gas leakage, so that the liquid level gauge can be used in winter. Since the disassembly column 10 and the plug are both detachable, the functions of convenient installation, maintenance and inspection can be achieved.

[0026] like Figure 2As shown, in some embodiments, a connecting flange 11 is fixed to the bottom of the lower cross tube 3, a running pipe 12 is installed at the bottom end of the connecting flange 11, a counterweight block 13 is slidably connected inside the running pipe 12, and a water tank 14 installed at the bottom of the lower cross tube 3 is provided on one side of the running pipe 12. When in use, the fixed connection of the connecting flange 11 makes the running pipe 12 more stable after being fixed, and at the same time can improve the sealing and applicability.

[0027] like Figure 5 As shown, in some embodiments, a liquid recovery pipe 15 is installed at the bottom end of the running pipe 12, and a support plate 16 is fixedly sleeved on the outer surface of the liquid recovery pipe 15, and the support plate 16 is fixed on the surface of the running pipe 12. When in use, the liquid recovery pipe 15, the support plate 16 and the running pipe 12 cooperate with each other to achieve the versatility of winter use and the function of fixed connection.

[0028] like Figure 3 As shown, in some embodiments, the trigger mechanism 7 includes a stainless steel bracket 701 installed on the surface of the lower horizontal tube 3, a stainless steel tube 702 is fixed to the top of the stainless steel bracket 701, and a stainless steel spring 703 fixed to the top of the stainless steel bracket 701 is provided inside the stainless steel tube 702. The top of the stainless steel spring 703 extends to the outside of the stainless steel tube 702 and is fixed with a trigger plate 704. When in use, the function of transmitting the trigger alarm can be achieved through the mutual cooperation of the stainless steel spring 703, the stainless steel tube 702 and the trigger plate 704.

[0029] like Figure 4 As shown, in some embodiments, the alarm mechanism 8 includes a mounting plate 801 fixed to a side wall of the lower transverse tube 3, and an alarm bell 802 is installed on one side wall of the mounting plate 801. When in use, the mounting plate 801 and the alarm bell 802 cooperate with each other to achieve the warning function.

[0030] The working principle and usage process of the utility model are as follows: PTFE pulleys are installed inside the upper transverse tube 1 and the lower transverse tube 3, and stainless steel wire ropes are provided on the surfaces of the two PTFE pulleys. The stainless steel wire ropes are respectively connected and fixed with the float end 5 and the counterweight 13, and a circular permanent magnet is installed at one place of the stainless steel wire rope. When loading crude oil, the float end 5 rises with the liquid level. When unloading crude oil, the float end 5 drops with the liquid level, and the permanent magnet is displaced inside the upper transverse tube 1 by the traction of the stainless steel wire rope. At this time, the magnetic principle of the magnet is utilized to affect the positive and negative pole changes of the movable plate on the liquid level plate 4. Since the colors of the front and back of the movable plate are different, the scale corresponding to the color-changing part is the height of the liquid level, which is convenient for staff to observe in different directions, so as to be applicable to various working conditions of well sites. By utilizing the gas diffusion principle and condensation principle, the steam baffle 9 can effectively prevent gas from overflowing, ensure the accuracy of liquid level measurement, and when the float end 5 moves up After detecting that the crude oil has been loaded to the highest liquid level, the stainless steel wire rope will drive the permanent magnet to move to a certain position on the upper cross tube 1. Since the trigger mechanism 7 is installed at the approved loading liquid level, the magnetic principle of the permanent magnet is utilized. When the loaded crude oil reaches the approved loading liquid level, the permanent magnet in the upper cross tube 1 will trigger the trigger piece 704, and then cooperate with the elastic force of the stainless steel spring 703 to drive the trigger piece 704 to move telescopically. Finally, after the trigger piece 704 moves, it can pull the alarm bell 802 to shake and alarm. Therefore, when the crude oil reaches the approved loading liquid level, it can play an early warning function to avoid overflow and oil leakage in the crude oil tanker. Therefore, the problem of failure of ordinary level gauges in winter and in heavy oil environments and malfunction of the level gauge due to oil-water mixed vapor is solved; secondly, the reliability and stability of the level gauge during vehicle movement are improved, and the float level gauge is combined with the research on the manhole cover of the vehicle to realize the completely enclosed loading and unloading function of the crude oil tanker.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
