Description

Technical Field

[0001] This utility model belongs to the field of oil temperature measurement technology, specifically relating to an insulated box for oil temperature detection. Background Technology

[0002] In oil temperature testing, it is typically necessary to measure the temperature at three points: the top, middle, and bottom of the oil. Traditionally, this involves inserting a thermometer into the oil and then removing it. However, the temperature displayed on the thermometer can change due to variations in air temperature and oil evaporation, leading to discrepancies between the measured and actual oil temperature. To improve the accuracy of oil temperature testing, current technology utilizes a thermometer insulation box to measure the oil temperature.

[0003] Chinese patent document CN220722178U discloses a multi-hole insulated temperature measuring box for installing an anti-theft plate on the metering port of an oil tank. The box includes an upper sleeve and an upper oil storage container. A glass liquid level thermometer is placed inside the sleeve, which has a diameter of 12mm. A thermometer hole connecting to an internal cavity is located at the center of the top of the oil storage container. Eight oil inlets connecting to the internal cavity are also located on the top of the oil storage container, each containing a spiral tower-type spring. The diameter of the oil storage container is 25mm. This technical solution allows for smooth passage through the anti-theft hole installed on the metering port of a gas station oil tank, ensuring sufficient liquid exchange and rapid temperature uniformity between the internal and external parts. It also ensures complete and full contact between the thermometer bulb and the liquid, guaranteeing the bulb is fully immersed in the oil being measured. This achieves the purpose and function of accurately measuring the temperature of the oil inside the tank manually.

[0004] Current insulated boxes are basically designed with a thermometer storage rod or liquid inlet at the top of the box. The extracted liquid cannot represent the temperature of the liquid at a certain depth, so the data reading is naturally not accurate. Moreover, after temperature acquisition, liquid recovery can only be done by pouring it out from the top inlet. It is difficult to pour out all the liquid from any angle, and the liquid is very easy to splash, especially dangerous liquids, which pose certain safety hazards. Utility Model Content

Detailed Implementation

[0029] like Figures 1-4 As shown, this embodiment provides an insulated box for oil temperature detection, including an oil storage container 1. The oil storage container 1 has an oil storage cavity inside, and a detection port 3 for installing a temperature measuring device 2 is opened on the oil storage container 1. The bottom of the oil storage container 1 has an oil inlet 4 communicating with the oil storage cavity, and the top of the oil storage container 1 has an oil overflow port 5 communicating with the oil storage cavity. A sealing plug 6 that can open or close the oil inlet 4 is movably installed in the oil storage cavity, and the sealing plug 6 is connected to a lifting mechanism 7.

[0030] In the initial state, due to the gravity of the sealing plug 6, the sealing plug 6 is located inside the oil inlet 4 and seals the oil inlet 4, preventing foreign objects from entering the oil inlet 4 and the oil storage chamber. When it is necessary to detect the oil temperature, the lifting mechanism 7 drives the sealing plug 6 to move upward, opening the oil inlet 4. At this time, the oil can enter the oil storage chamber through the oil inlet 4, and excess oil overflows through the overflow port 5 at the top. Then, the lifting mechanism 7 drives the sealing plug 6 to move downward, closing the oil inlet 4. The temperature measuring device 2 is then used to detect the oil temperature in the oil storage chamber.

[0031] This invention allows for liquid inlet at the actual oil sampling location, employing a bottom inlet and top overflow design. This enables precise and effective extraction of liquid at a fixed level, resulting in accurate temperature data for that level. The precise sampling improves the accuracy of oil testing. Furthermore, the lifting mechanism 7 drives the sealing plug 6 to open the oil inlet 4, allowing the liquid to be discharged centrally through the bottom inlet 4. This effectively prevents liquid splashing and enhances the convenience and safety of liquid recovery.

[0032] In one specific embodiment, the inner wall of the oil inlet 4 is provided with a first sealing slope, and the periphery of the sealing plug 6 is provided with a second sealing slope adapted to the first sealing slope. Preferably, the cross-sections of both the oil inlet 4 and the sealing plug 6 are isosceles trapezoidal structures. Typically, both the oil inlet 4 and the sealing plug 6 are circular, and the sealing plug 6 can seal the oil inlet 4 under the action of gravity.

[0033] In one specific embodiment, the lifting mechanism 7 includes a lifting rod, one end of which is connected to the sealing plug 6, and the other end of which extends to the outside of the oil storage container 1. The sealing plug 6 can be moved up and down via the lifting rod. Figure 3 As shown, the lifting rod includes a handle 8 and a threaded sleeve 9. The threaded sleeve 9 is mounted on the sealing plug 6, and one end of the handle 8 is threadedly connected to the threaded sleeve 9. Preferably, the end of the handle 8 extending to the outside of the oil storage container 1 is provided with a handle head 10. The handle head 10 can be designed with a cross-groove structure or a hexagonal head to facilitate the rotation of the handle 8, thereby enabling the connection and disassembly of the handle 8 and the threaded sleeve 9.

[0034] like Figure 1 and Figure 2 As shown, in order to reduce the evaporation of oil, the oil storage container 1 is provided with a pressure plate 11 for covering the oil overflow port 5, and the pressure plate 11 has a through hole adapted to the lifting rod. Preferably, the top of the oil storage container 1 has a positioning groove adapted to the pressure plate 11.

[0035] To improve the stability of the sealing plug 6 during lifting and lowering, a guiding mechanism is provided inside the oil storage container 1. The guiding mechanism guides the lifting and lowering movement of the sealing plug 6 to open or close the oil inlet 4. Specifically, the guiding mechanism includes a plurality of guide posts 12 arranged in a ring. The guide posts 12 are located around the sealing plug 6 and slide in contact with the sealing plug 6 to guide the sealing plug 6.

[0036] like Figure 2 As shown, in this embodiment, the oil storage container 1 includes an oil storage cylinder 13 and a base platform 14 connected to each other. The oil storage cylinder 13 has an oil storage chamber inside, and an overflow port 5 is provided at the top of the oil storage cylinder 13. The base platform 14 is located at the bottom of the oil storage cylinder 13, and an oil inlet 4 is provided on the base platform 14. The guiding mechanism includes three guide posts 12, which are arranged in a ring on the base platform 14. The base platform 14 is installed at the bottom of the oil storage cylinder 13, and the guide posts 12 extend into the oil storage chamber to prevent the sealing plug 6 from deviating during lifting and lowering.

[0037] like Figure 4As shown, in one specific embodiment, the temperature measuring device 2 includes a storage cylinder 15, inside which a thermometer 16 is installed. One end of the storage cylinder 15 extending into the oil storage chamber has an oil inlet / outlet hole 17. Oil from the oil storage chamber enters the storage cylinder 15 through the oil inlet / outlet hole 17 and comes into contact with the temperature-sensing bulb of the thermometer 16, thus achieving oil temperature detection. After detection, the oil inside the storage cylinder 15 is discharged into the oil storage chamber through the oil inlet / outlet hole 17. The surface of the storage cylinder 15 has external threads, and the detection port 3 has internal threads adapted to the external threads. The two ends of the storage cylinder 15 are respectively provided with an upper sealing head 18 and a lower sealing head 19. A spring 20 is provided between the lower sealing head 19 and the thermometer 16. The temperature-sensing bulb of the thermometer 16 extends into the inside of the spring 20 and comes into contact with the oil. The spring 20 provides a buffering effect on the thermometer 16 and increases the preload of the thermometer 16, improving the safety of the thermometer 16 in use. The storage cylinder 15 has an observation window 21 and a light-transmitting window 22 on its surface. The observation window 21 is located on the front of the thermometer 16. The light-transmitting window 22 is located on the back of the thermometer 16, allowing for convenient observation of the oil temperature detected by the thermometer 16.

[0038] This invention, based on the actual sampling location of the oil, adopts a bottom-filling, top-overflowing design. Liquid enters from the bottom and exits from the top. During the descent of the insulated box, internal liquid replacement is completed. When the appropriate liquid level is reached, the insulated box is lifted upwards, and the top pressure plate 11 blocks the upper oil inlet 4. The sealing plug 6 slides down to block the oil inlet 4, achieving the function of preventing liquid from entering from the top and exiting from the bottom during the lifting process. Furthermore, the sampled liquid is kept as uncontaminated as possible, resulting in a more accurate temperature reading. After the test is completed, the liquid needs to be recovered. This can be achieved by directly lifting the pre-installed handle 8 at the top, sliding the sealing plug 6 upwards to open the oil inlet 4, and then the liquid is discharged from the bottom oil inlet 4.

[0039] The handle 8 passes through the pressure plate 11 and is threadedly connected to the threaded sleeve 9. The sealing plug 6 moves up and down under the guidance of three guide posts 12 to avoid travel deviation. A spring 20 is added to the bottom of the storage cylinder 15 to support the temperature sensing bulb of the thermometer 16, which has the function of shock absorption to prevent the thermometer 16 from breaking. The rod extends into the middle of the main body. Oil inlet and outlet holes 17 are designed around the perimeter of the storage cylinder 15 to ensure that the temperature sensing bulb of the thermometer 16 is fully immersed in the liquid and in full contact with the liquid, thereby improving the temperature detection accuracy.
