A daily fuel tank water testing device

Abstract

This utility model discloses a water content testing device for daily-use fuel tanks, including a support member with a long rod-like structure, a winding mechanism disposed on the support member, a traction rope connected to the winding mechanism, and a detection element connected to the free end of the traction rope. The detection element has a receiving groove for accommodating the detection reagent. The winding mechanism is used to wind or unwind the traction rope to control the raising and lowering of the detection element. The detection element extends into the bottom of the daily-use fuel tank, allowing the detection reagent to contact the daily-use fuel. By observing the range and depth of the color change of the detection reagent, the water content in the daily-use fuel is predicted. This allows operators to place and retrieve the detection element while standing on the ground, eliminating the need to enter a confined fuel tank area or climb a ladder, simplifying the operation process and significantly improving the convenience of water content testing in daily-use fuel tanks. It also avoids the need for operators to use ladders in confined spaces, fundamentally eliminating the safety hazard of ladder falls and ensuring the personal safety of maintenance personnel.

Description

Technical Field

[0001] This utility model relates to the field of fuel tank testing technology, and in particular to a daily fuel tank water testing device. Background Technology

[0002] In the daily operation and maintenance of data centers, the daily fuel tanks in diesel generator rooms need to be regularly checked for water accumulation in the diesel fuel (i.e., the water content of the diesel fuel) to ensure the normal operation of the diesel generators. Currently, the commonly used diesel fuel water testing device in the industry consists of rollers, copper weights, and measuring tapes. Although this device is suitable for testing large fuel tanks, it has the following drawbacks when applied to daily fuel tanks: the operating space in daily fuel tank rooms is usually small, and the access ports of daily fuel tanks are generally located at high positions. When using traditional water testing devices, operators must use ladders to drop and retrieve the copper weights. This is not only cumbersome and extremely inconvenient, but also poses a safety risk of personnel accidentally falling while using ladders in confined spaces. It is difficult to meet the needs of efficient and safe water testing of daily fuel tanks. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a daily oil tank water testing device.

[0004] This utility model proposes a water content testing device for daily-use oil tanks, comprising a support member with a long rod-like structure, a winding mechanism disposed on the support member, a traction rope connected to the winding mechanism, and a detection element connected to the free end of the traction rope. The detection element is provided with a receiving groove for accommodating a detection reagent. The winding mechanism is used to wind or unwind the traction rope to control the raising and lowering of the detection element. The detection element extends into the bottom of the daily-use oil tank, allowing the detection reagent to contact the daily-use oil. By observing the range and depth of the color change of the detection reagent, the water content in the daily-use oil can be predicted.

[0005] Preferably, the winding mechanism includes a rotatable shaft whose axis is perpendicular to the axis of the support member, and the shaft is mounted on the support member at one end away from the detection member.

[0006] Preferably, a rotating handle is installed at the end of the rotating shaft.

[0007] Preferably, the detection element is a stainless steel oil sinker, and the stainless steel oil sinker is detachably connected to the traction rope.

[0008] Preferably, the test reagent is a test paste.

[0009] Preferably, the end of the support member is provided with a non-slip handle.

[0010] In summary, this utility model has the following beneficial effects: During testing, the free end of the support member is aligned with the inspection port of the daily oil tank. The winding mechanism is rotated, and the traction rope is released. Due to its own weight, the test piece sinks from the inspection port to the bottom of the daily oil tank, allowing the test reagent to come into contact with the daily oil. By observing the range and depth of the color change of the test reagent, the water content in the daily oil can be predicted. Thus, compared to traditional devices that require the use of a ladder, this device, through the length design of the support member, allows operators to complete the placement and retrieval of the test piece while standing on the ground, eliminating the need to enter a confined oil tank room or climb a ladder. This simplifies the operation process and significantly improves the convenience of testing the water content in daily oil tanks, especially suitable for confined daily oil tank rooms. Simultaneously, it avoids the need for operators to use ladders in confined spaces, fundamentally eliminating the safety hazard of ladder falls, ensuring the personal safety of maintenance personnel, and meeting the safety management requirements for daily operation and maintenance of data centers.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] like Figure 1 As shown in this embodiment, a water-testing device for daily-use oil tanks includes a support member with a long rod-like structure, a winding mechanism disposed on the support member, a traction rope 3 connected to the winding mechanism, and a detection element connected to the free end of the traction rope 3. The detection element is provided with a receiving groove 11 for accommodating the detection reagent. The winding mechanism is used to wind or unwind the traction rope 3 to control the lifting and lowering of the detection element. The detection element extends into the bottom of the daily-use oil tank, so that the detection reagent comes into contact with the daily-use oil. By observing the range and depth of the color change of the detection reagent, the water content in the daily-use oil can be predicted.

[0017] Specifically, the support can be made of high-strength steel pipe (i.e. support steel pipe 2), with sufficient rigidity and length. Its length is designed according to the height of the daily fuel tank inspection port, ensuring that when the operator is standing on the ground, the inspection piece can be delivered to the bottom of the fuel tank through the support.

[0018] Thus, compared to traditional devices that require the use of ladders, this device, through the length design of its support components, allows operators to place and retrieve test items while standing on the ground, eliminating the need to enter confined fuel tank rooms or climb ladders. This simplifies the operation process and significantly improves the convenience of daily fuel tank testing, making it particularly suitable for confined daily fuel tank rooms. Furthermore, it avoids the need for operators to use ladders in confined spaces, fundamentally eliminating the safety hazard of ladder falls and ensuring the personal safety of maintenance personnel, thus meeting the safety management requirements for daily data center operations.

[0019] Furthermore, the winding mechanism includes a rotatable shaft 4, the axis of which is perpendicular to the axis of the support member. The shaft 4 is mounted on the support member at the end away from the detection member. The shaft 4 is made of metal, and its two ends are rotatably connected to the welded parts of the support member through bearings to ensure that the shaft 4 can rotate flexibly. The length of the shaft 4 is slightly shorter than the diameter of the support steel pipe 2 to avoid interference with other components during rotation.

[0020] Furthermore, the end of the support is provided with a non-slip handle 21 to increase the friction between the operator's hand and the support pipe 2.

[0021] Meanwhile, a rotating handle 41 is installed at the end of the rotating shaft 4. This allows the operator to manually rotate the rotating shaft 4, thereby controlling the release and retraction of the traction rope 3.

[0022] In this embodiment, the detection component is a stainless steel oil sinker 1, which is detachably connected to the traction rope 3. Stainless steel is corrosion-resistant and has a high density, allowing it to sink stably to the bottom of the fuel tank in diesel fuel. The detection reagent is a water-repellent paste, which changes color upon contact with water in the diesel fuel, allowing for subsequent observation of the color to determine the water content of the diesel fuel.

[0023] Furthermore, the top of the stainless steel oil sinker 1 is equipped with a hanging ring for connecting to the traction rope 3. The traction rope 3 is made of high-strength, corrosion-resistant nylon rope or steel wire rope. One end of the traction rope 3 is wrapped around the outer wall of the rotating shaft 4, and the winding or unwinding is achieved by rotating the shaft 4. The other end of the traction rope 3 is fixedly installed with a hook, which is detachably connected to the hanging ring at the top of the stainless steel oil sinker 1, facilitating the replacement and maintenance of the stainless steel oil sinker 1.

[0024] In use, first, fill an appropriate amount of test paste into the receiving groove 11 of the stainless steel oil sinker 1, ensuring that the test paste fills the receiving groove 11 completely and the surface is flat; then, securely connect the hook at the end of the traction rope 3 to the hanging ring at the top of the stainless steel oil sinker 1; the operator stands on the ground next to the daytime fuel tank, holds the middle of the support steel pipe 2 with one hand, and rotates the shaft 4 with the other hand to slowly release the traction rope 3; align the free end of the support steel pipe 2 with the inspection port of the daytime fuel tank, and as the traction rope 3 is released, the stainless steel oil sinker 1, under its own gravity, slowly sinks to the bottom of the fuel tank along the inspection port. During the process, the sinking speed of the stainless steel oil sinker 1 can be adjusted by controlling the rotation speed of the shaft 4 to avoid damage caused by the oil sinker colliding with the inner wall of the fuel tank due to excessive sinking speed; the stainless steel oil sinker 1 stays at the bottom of the fuel tank for a preset time (usually...). After 3-5 minutes (ensuring the test paste is in full contact with the diesel), the operator reverses the rotation shaft 4, winds the traction rope 3, and slowly pulls the stainless steel oil sinker 1 out of the fuel tank. Once the stainless steel oil sinker 1 is completely detached from the fuel tank, remove the connection between the hook and the hanging ring, take out the stainless steel oil sinker 1, and observe the color change of the test paste in the container 11: if the test paste does not change color, it indicates that there is no obvious water in the diesel; if the test paste shows a specific color (such as changing from yellow to red, the specific color change depends on the test paste model), predict the water content in the diesel based on the range and depth of the color change; after the test is completed, clean the remaining test paste in the container 11 of the stainless steel oil sinker 1, completely wind the traction rope 3 onto the rotation shaft 4, disconnect the connection between the hook and the hanging ring, and neatly store all parts for the next use.

[0025] Specifically, the prediction of diesel fuel water content based on the color of the water test paste is as follows: If the water test paste remains the initial pale yellow, it indicates that the diesel fuel water content is below 0.05%, which meets the usage requirements; if red spots appear on the water test paste, and the red area accounts for less than 10%, it indicates that the diesel fuel water content is between 0.05% and 0.1%, and the monitoring frequency needs to be increased; if the red area accounts for more than 10%, it indicates that the diesel fuel water content exceeds 0.1%, and the diesel fuel in the fuel tank needs to be dehydrated in a timely manner.

[0026] It should be noted that the daily fuel tank water testing device in this embodiment is mainly for testing the water content of diesel fuel.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
