Description

Technical Field

[0001] This utility model relates to the field of oil and gas field storage tank technology, and in particular to a liquid level observation device and a liquid storage tank system. Background Technology

[0002] In drilling, fracturing, and oil refining operations, square or round tanks are often used to hold working fluids. Especially in confined areas, where the pumping equipment is far from the tank, the water level difference in the low-pressure pipeline reduces the pumping efficiency. Typically, a storage tank is placed at the rear of the pumping equipment for secondary fluid supply. Due to the small volume of the storage tank, personnel must constantly move to the storage tank to observe the liquid level during operation. This allows for timely notification of pumping personnel to replenish the working fluid in the storage tank when the level is low to medium, preventing the tank from running dry. Therefore, close-range manual observation of the liquid level is necessary both day and night, significantly increasing the workload and posing a major safety hazard to the observers as they must enter the high-pressure work area. Utility Model Content

[0003] The purpose of this utility model is to address the problem in the background art that in order to prevent the liquid tank from being emptied, it is necessary to manually observe the liquid level at close range, which not only adds a lot of workload to the on-site construction, but also poses a safety hazard because personnel need to enter the high-pressure construction area. This utility model provides a liquid level observation device and a liquid storage tank system.

[0004] In a first aspect, the present invention provides a liquid level observation device, comprising:

[0005] outer cylinder;

[0006] A base that is detachably connected to the bottom of the outer cylinder;

[0007] A detachable top cover is attached to the top of the outer cylinder, and a central cylinder is detachably attached to the end of the top cover away from the outer cylinder.

[0008] A float is disposed inside the outer cylinder, and a central rod is detachably connected to the float. The central rod is coaxial with the central cylinder and slides through the central cylinder and extends to the outside of the central cylinder.

[0009] A water inlet area is vertically provided on the side wall of the outer cylinder.

[0010] Preferably, the float is provided with a connector, and the center rod is threaded to the connector.

[0011] Preferably, the base is threadedly connected to the bottom of the outer cylinder;

[0012] The bottom of the upper cover is threadedly connected to the top of the outer cylinder.

[0013] Preferably, the central cylinder is threaded to the top of the upper cover.

[0014] Preferably, the central cylinder is provided with a linear bearing, and the central rod is slidably engaged with the linear bearing.

[0015] Preferably, the water inlet area includes multiple vertically arranged strip-shaped openings.

[0016] Preferably, the base is further provided with a drain hole, which is connected to the inside of the outer cylinder.

[0017] Preferably, the upper part of the central rod is provided with a fluorescent area.

[0018] Preferably, a magnet is installed at the bottom of the base.

[0019] In a second aspect, the present invention provides a liquid storage tank system, including a tank body and a liquid level observation device as described in this application, wherein the observation device is vertically placed on the tank body, the base abuts against the bottom of the tank body, and the central cylinder extends outside the tank body;

[0020] The tank body is also provided with a water inlet, and the water inlet area is located on the side of the outer cylinder away from the water inlet.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The liquid level observation device of this application, when performing liquid level detection in a tank, is placed vertically inside the tank with the base in contact with the bottom of the tank and the central cylinder located outside the tank. The float inside the tank moves upward due to the buoyancy of the working fluid, pushing the central rod through the central cylinder to the outside of the tank. Personnel can determine the liquid level position by observing the height of the central rod from a distance. This effectively solves the problem of personnel needing to move to the tank in real time to observe the liquid level inside the tank, and also avoids personnel entering the high-pressure construction area, ensuring the safety of personnel. Furthermore, the central cylinder is detachably connected to the top cover, and the central rod is coaxial with the central cylinder. The central rod slides through the central cylinder and extends to the outside of the central cylinder, supporting the central rod and preventing large swaying of the central rod during up and down movement. Furthermore, since the outer cylinder is detachably connected to the base and the top cover, and the float is detachably connected to the central rod, the liquid level observation device of this application can adapt to tanks of different heights by changing the outer cylinder and the central rod of the corresponding height, effectively increasing the scope of application of this application.

[0023] 2. A liquid storage tank system of this application, wherein a liquid level observation device is vertically placed inside the tank, the base of the observation device abuts against the bottom of the tank, the central cylinder of the observation device extends to the outside of the tank, the float moves upward inside the tank due to the buoyancy of the working fluid, pushing the central rod through the central cylinder to the outside of the tank, and personnel can judge the liquid level position by observing the height of the central rod from a distance, so that the operator can add liquid to the tank according to the liquid level position, avoiding the tank being emptied. Furthermore, the tank is also provided with a water inlet. When adding working fluid to the tank through the water inlet, since the water inlet area is located on the side of the outer cylinder away from the water inlet, it can effectively avoid the injected liquid directly impacting the outer cylinder, and avoid the injected liquid impacting the float and central rod, causing the float and central rod to collide with the outer cylinder and be damaged.

[0037] Example 1

[0038] like Figures 1-3 As shown, this embodiment discloses a liquid level observation device, including a base 1, an outer cylinder 2, a top cover 3, a central cylinder 4, a float 5, and a central rod 8. The base 1 is detachably connected to the bottom of the outer cylinder 2, the bottom of the top cover 3 is detachably connected to the top of the outer cylinder 2, and the central cylinder 4 is detachably connected to the top of the top cover 3. The float 5 is located inside the outer cylinder 2, and the central rod 8 is detachably connected to the float 5. The central rod 8 is coaxial with the central cylinder 4, and the central rod 8 slides through the central cylinder 4 and extends to the outside of the central cylinder 4. A water inlet area is vertically provided on the side wall of the outer cylinder 2.

[0039] In this embodiment, when detecting the liquid level in tank 30, the liquid level observation device is placed vertically inside tank 30, with base 1 in contact with the bottom of tank 30, and central cylinder 4 located outside tank 30. Float 5 moves upward inside tank 30 due to the buoyancy of the working fluid, pushing central rod 8 through central cylinder 4 to the outside of tank 30. Personnel can determine the liquid level position by observing the height of central rod 8 from a distance. This effectively solves the problem of personnel needing to move to tank 30 in real time to observe the liquid level inside the tank, while also preventing personnel from entering the high-pressure construction area, thus ensuring the safety of personnel during operation.

[0040] Furthermore, the upper cover 3 is detachably connected to the central cylinder 4, the central rod 8 is coaxial with the central cylinder 4, and the central rod 8 slides through the central cylinder 4 and extends to the outside of the central cylinder 4. The central cylinder 4 supports the central rod 8 to prevent the central rod 8 from shaking too much during up and down movement.

[0041] Furthermore, since the outer cylinder 2 is detachably connected to the base 1 and the top cover 3, and the float 5 is detachably connected to the central rod 8, when facing tanks 30 of different heights, by replacing the outer cylinder 2 and the central rod 8 of the corresponding height, the liquid level observation device of this embodiment can adapt to tanks 30 of different heights, effectively increasing the scope of application of this application.

[0042] The central cylinder 4 has a vertical channel inside for the central rod 8 to pass through. The inner wall of the vertical channel is smooth to reduce the friction when the central rod 8 passes through.

[0043] In one or more implementations, such as Figure 2 As shown, the float 5 is provided with a connector 6, and the center rod 8 is threaded onto the connector 6.

[0044] The connector 6 is a metal component, the float 5 is a hollow thin-walled steel ball, the connector 6 is connected to the float 5 by welding, and the center rod 8 is threaded onto the connector 6 to enable quick disassembly of the center rod 8.

[0045] In this application, the float 5 has a sufficiently large drainage volume to generate enough buoyancy to support the weight of the central rod 8 and its own weight. The specific dimensions of the float 5 are designed with reference to actual needs and the weight of the central rod 8.

[0046] Furthermore, connector 6 is a steel pipe, and a transverse partition 61 is installed inside connector 6, such as... Figure 2 As shown, the diaphragm 61 is located in the middle area of ​​the connector 6. The connector 6 is divided into two parts by the diaphragm 61. When there is a gap at the welding point between the connector 6 and the float 5, the diaphragm 61 will block the working fluid from entering the center rod 8, effectively preventing the working fluid from entering the center rod 8 and affecting the buoyancy of the float 5.

[0047] In one or more implementations, such as Figure 1 As shown, the base 1 is threadedly connected to the bottom of the outer cylinder 2;

[0048] The bottom of the upper cover 3 is threadedly connected to the top of the outer cylinder 2.

[0049] In an optional embodiment, the central cylinder 4 is threaded to the top of the upper cover 3.

[0050] Specifically, the bottom of the outer cylinder 2 is provided with a first external thread, and the top of the outer cylinder 2 is provided with a first internal thread;

[0051] The base 1 has a second internal thread on its side wall that matches the outer cylinder 2, and the top cover 3 has a second external thread on its bottom that matches the outer cylinder 2;

[0052] The outer cylinder 2 and the base 1 are connected by a first external thread and a second internal thread, and the outer cylinder 2 and the upper cover 3 are connected by a first internal thread and a second external thread.

[0053] The top of the upper cover 3 is provided with a third internal thread, and the bottom of the central cylinder 4 is provided with a third external thread. The upper cover 3 and the central cylinder 4 are connected by the third internal thread and the third external thread.

[0054] In optional implementations, such as Figure 4 As shown, the water inlet area 9 includes multiple vertically arranged strip openings 91.

[0055] The adjacent strip openings 91 are spaced apart.

[0056] Furthermore, the water inlet zone 9 occupies one-twelfth of the outer wall of the outer cylinder 2. Specifically, with reference to the 360° circumference of the outer cylinder 2, the water inlet zone 9 occupies 90° to 120° of the circumference of the outer cylinder 2.

[0057] In an optional embodiment, a fluorescent area is provided on the upper part of the central rod 8. This facilitates observation of the height of the central rod 8 at night.

[0058] In optional implementations, such as Figure 1 As shown, the base 1 is also provided with a drain hole 10, which is connected to the inside of the outer cylinder 2. By providing the drain hole 10, when the liquid level observation device needs to be removed, the working fluid that has entered the outer cylinder 2 can flow out from the drain hole 10 on the base 1, thus preventing the working fluid from remaining in the outer cylinder 2.

[0059] Example 2

[0060] Based on Example 1, such as Figure 1 As shown in the figure, in this embodiment of the liquid level observation device, a magnet 20 is installed at the bottom of the base 1. The magnet 20 is used to attract the bottom of the tank 30, thereby ensuring the stability of the liquid level observation device.

[0061] Example 3

[0062] Based on Example 1 or Example 2, such as Figure 3 As shown in the embodiment, a liquid level observation device is provided with a linear bearing 7 on the central cylinder 4, and the central rod 8 is slidably engaged with the linear bearing 7.

[0063] The linear bearing 7 is located at the top of the central cylinder 4, and the central rod 8 passes through the linear bearing 7 to reduce the friction force experienced by the central rod 8 during its movement.

[0064] Specifically, the linear bearing 7 is installed on the top of the central cylinder 4, and a cap 40 is fitted on the linear bearing 7. The cap 40 is connected to the central cylinder 4 by screws 50.

[0065] Example 4

[0066] like Figure 5 As shown, this embodiment discloses a liquid storage tank system, including a tank body 30 and a liquid level observation device as described in Embodiments 1 to 3. The observation device is placed vertically on the tank body 30, the base 1 abuts against the bottom of the tank body 30, and the central cylinder 4 extends outside the tank body 30.

[0067] The tank body 30 is also provided with a water inlet 301, and the water inlet area 9 is located on the side of the outer cylinder 2 away from the water inlet 301.

[0068] In this embodiment of the liquid storage tank system, a liquid level observation device is vertically placed inside the tank body 30. The base 1 of the observation device abuts against the bottom of the tank body 30, and the central cylinder 4 of the observation device extends to the outside of the tank body 30. The float 5 moves upward inside the tank body 30 due to the buoyancy of the working fluid, pushing the central rod 8 through the central cylinder 4 to the outside of the tank body 30. Personnel can determine the liquid level position by observing the height of the central rod 8 from a distance, so that the operators can add liquid to the tank body 30 according to the liquid level position, and avoid the tank body 30 being emptied.

[0069] Furthermore, the tank body 30 is also provided with a water inlet 301. When the working fluid is replenished to the tank body 30 through the water inlet 301, since the water inlet area 9 is located on the side of the outer cylinder 2 away from the water inlet 301, it can effectively prevent the injected liquid from directly impacting the outer cylinder 2 and prevent the injected liquid from impacting the float ball 5 and the center rod 8, which could cause the float ball 5 and the center rod 8 to collide with the outer cylinder 2 and be damaged.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
