Description

Technical Field

[0001] This utility model relates to the field of oil temperature measurement technology, and in particular to an oil temperature measuring box and an oil temperature measuring device. Background Technology

[0002] Oil depots typically use volumetric flow meters to deliver oil to tanker trucks, which are then transported to gas stations. Gas station dispensers also measure by volume, a process known as "lift in, lift out." However, the volume of the same type of oil can vary depending on temperature. Furthermore, during processing, transportation, storage, and use, oil can be contaminated with moisture for various reasons. Therefore, at the end of each month, gas station operators must manually measure and record the oil level, water level, and oil temperature in the tanks during inventory checks. This data is then compared with level gauge data and recorded in a cloud platform to determine the actual quantity of oil in stock and verify any oil losses (surpluses).

[0003] Currently, gas station operators typically use insulated temperature measuring boxes with built-in thermometers to manually measure the temperature of fuel inside the tanks. During operation, the measuring box is lowered into the tank using a suspension rope to take a sample. However, this method has the following problems in actual production: 1. Residual fuel in the box can only be poured out through the top inlet, making it inconvenient and difficult to empty completely. 2. The suspension rope tends to absorb oil during use and leaves oil residue afterward, making cleaning difficult. Reusing the rope can lead to fuel contamination and rope tangling. Summary of the Invention

[0004] The purpose of this invention is to provide an oil temperature measuring box that facilitates the discharge of residual oil from the box; in addition, it also provides an oil temperature measuring device that is easy to operate and clean.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an oil temperature measuring box, characterized in that: it includes a thermometer, a thermometer mounting tube, a box body with an open bottom, a box bottom cover, and an oil drain valve; one side of the thermometer mounting tube is provided with an elongated hole; a lifting lug is connected to the top of the thermometer mounting tube; the bottom end of the thermometer mounting tube is fixedly connected to the top surface of the box body, thereby communicating with the inner cavity of the box body; an oil inlet hole is provided on the top surface of the box body; and an oil drain hole is provided on the box bottom cover. A spring is installed in the center of the bottom cover, and a support baffle is installed in the upper part of the spring. The thermometer is placed in the thermometer mounting tube and the lower end of the thermometer is inserted into the spring. After the bottom cover is connected and fixed to the box body, the temperature scale of the thermometer is placed in the elongated hole. The oil drain valve includes a valve body connected to the bottom cover and a sealing ball set in the inner cavity of the valve body. The lower part of the valve body is funnel-shaped, and the center of the bottom surface of the valve body is the oil drain hole. When the sealing ball falls into the oil drain hole, the oil drain valve is closed; when the sealing ball leaves the oil drain hole, the oil drain valve is opened.

[0006] Furthermore, a through hole, matching the size of the thermometer mounting tube, is formed at the center of the top surface of the housing. The bottom end of the thermometer mounting tube is inserted into the through hole and welded in place. Alternatively, a screw hole is formed at the center of the top surface of the housing, and the bottom end of the thermometer mounting tube is threaded into the screw hole.

[0007] Furthermore, multiple oil inlets and outlets are provided.

[0008] Furthermore, the top edge of the valve body is provided with a chamfered bevel.

[0009] In addition, this utility model also discloses an oil temperature measuring device, characterized in that: it includes an oil measuring tape body and the above-mentioned oil temperature measuring box, and the movable end of the measuring tape body is connected to the lifting lug of the oil temperature measuring box.

[0010] The beneficial effects of this utility model are: the oil temperature measuring box of this utility model is equipped with an oil drain valve. When using it, after the operator has read the temperature, he only needs to hold the protective sleeve and tilt the box slightly to drain the oil from the box. It can drain the oil from the box very conveniently and thoroughly.

[0011] In addition, the oil temperature measuring device disclosed in this utility model uses a dipstick body instead of the existing cotton rope, which can accurately determine the position of the oil temperature measurement during measurement, and is also easy to clean and store after the measurement is completed.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, this utility model discloses an oil temperature measuring box, which includes a thermometer 1, a thermometer mounting tube 2, a box body 3 with an open bottom surface, a box bottom cover 4, and an oil drain valve.

[0019] The thermometer mounting tube 2 has an elongated hole 21 on one side, a lifting lug 7 connected to its top end, and its bottom end fixedly connected to the top surface of the housing 3. The thermometer mounting tube 2 and the housing 3 can be fixed by welding. Specifically, a through hole of the same size as the thermometer mounting tube can be made at the center of the top surface of the housing, and the bottom end of the thermometer mounting tube can be inserted into the through hole and welded in place. Alternatively, it can be fixed by threaded connection. Specifically, a threaded hole can be made at the center of the top surface of the housing, and the bottom end of the thermometer mounting tube can be threaded to mate with the threaded hole, thus connecting the bottom end of the thermometer mounting tube to the threaded hole. After connection, the inner cavity of the thermometer mounting tube 2 communicates with the inner cavity of the housing 3, allowing the thermometer to pass through the inner cavity of the housing and enter the inner cavity of the thermometer mounting tube 2. An oil inlet hole 31 is provided on the top surface of the housing 3; an oil drain hole 41 is provided on the bottom cover of the housing. A spring 6 is installed in the center of the bottom cover 4. A support plate 7 is installed in the upper part of the spring 6. During assembly, the lower end of the thermometer is inserted into the spring 6 and contacts the support plate 7. Then it is inserted into the thermometer mounting tube 2. Finally, the bottom cover 4 is threaded to the box body 3, so that the temperature scale of the thermometer is placed in the elongated hole 21 of the thermometer mounting tube 2 for easy observation and reading.

[0020] The drain valve includes a valve body 8 and a plugging ball 9 disposed in the inner cavity of the valve body. The upper part of the valve body 8 is open and threadedly connected to the bottom cover 4 of the box. The lower part of the valve body 8 is funnel-shaped, and the center of the bottom surface of the valve body is a drain hole 81. When the plugging ball 9 falls into the drain hole 81, the drain valve is closed; when the plugging ball 9 leaves the drain hole 81, the drain valve is opened.

[0021] During measurement, the oil enters the housing through the oil inlet 31, and then enters the valve body 8 through the oil outlet 41.

[0022] Specifically, such as Figure 4 As shown, the top edge of the valve body 8 is provided with a chamfered bevel 82. This chamfered bevel 82 prevents oil from accumulating and being carried out of the tank during the lifting process. The inner bottom surface of the valve body 8 is lower at the center and higher around the edges; that is, the oil drain hole 81 is at the lowest point. When the oil temperature measuring box is in a vertical position, the steel ball 9 will roll down onto the oil drain hole 81 under gravity, closing the oil drain valve. When the oil temperature measuring box is tilted at a certain angle, the steel ball 9 will drain through the oil drain hole 81, opening the oil drain valve. During use, to make the steel ball 9 leave the oil drain hole 81 more quickly, it can be shaken up and down slightly while tilting.

[0023] Furthermore, multiple oil inlet holes 31 and multiple oil outlet holes 41 are provided to accelerate the oil inlet efficiency.

[0024] like Figure 5As shown, this utility model also discloses an oil temperature measuring device, including an oil measuring tape body 100 and the aforementioned oil temperature measuring box 300. Specifically, the oil measuring tape body is the remaining part of an existing oil measuring tape after removing the measuring tape tip, and then the movable end of the measuring tape is connected to the lifting lug of the oil temperature measuring box through a lifting ring 200. It is easy to retract and extend during use, convenient to operate, and can also record the position of the measured oil temperature.

[0025] The process of measuring oil temperature using a measuring device is as follows:

[0026] 1) Open the oil tank metering port;

[0027] 2) Loosen the dipstick, lower the oil temperature measuring box to the temperature measuring position, and lift the oil temperature measuring box up and down 3 times (the oil temperature measuring box moves up and down a distance of about 20cm); the oil enters the body of the oil temperature measuring box and the valve body;

[0028] 3) Allow the oil temperature measuring box to remain at the measuring position for the specified time to allow it to reach temperature equilibrium with the surrounding oil.

[0029] 4) Quickly and vertically remove the oil temperature measuring box from the oil and read the value immediately (the oil inside the box must not overflow at this time). When reading the value, do not touch the insulated box with your hands. Your line of sight should be horizontal with the temperature reading. Read the decimal first and then the large number, and record it.

[0030] 5) Tilt and shake the oil temperature measuring box to dislodge the steel ball from the drain hole and drain the oil from the box and valve body.

[0031] 6) Measure the temperature at the next location according to the oil temperature measurement requirements, and repeat steps 2) to 5) until the temperature measurement at all locations is completed;

[0032] 7) Calculate the average of all measured temperatures as the average temperature of the oil in the tank.

[0033] The oil temperature measuring device disclosed in this utility model uses an oil measuring dipstick instead of the black cotton rope. It is used in conjunction with the oil temperature measuring box disclosed in this utility model, making it clean and hygienic. The oil measuring dipstick has a built-in retractable roller for easy storage. When draining the oil, simply tilt and shake the box slightly to dislodge the steel ball from the drain port, and the remaining oil can be poured out completely.

[0034] Since measuring oil temperature is a daily necessity for gas stations, tools for measuring oil temperature are needed in every gas station. The oil temperature measuring device of this utility model makes daily work more convenient, time-saving, and labor-saving, and the storage is more standardized and hygienic, which has good practicality and promotion value.

[0035] The above description is only used to illustrate the technical solution of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
