Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery device used for oil drilling activities. Background Art

[0002] Oil drilling is a process of drilling into geological layers in marine or land environments to explore whether there are oil resources underground. During the exploration process, detection components are often needed to accurately determine whether there are oil resources underground.

[0003] In addition, exploration drill bits are often exposed to high temperature and high pressure environments when drilling into geological formations. The drill bits and detection components are subject to temperatures of 150°C and above, as well as high-frequency vibrations. While the drill bits themselves are inherently hard and have strong high-temperature resistance, the detection components contain relatively fragile battery packs. Consequently, during oil drilling activities, the battery packs are prone to overheating, affecting the use of the measuring components within the detection components. Furthermore, under high-frequency vibrations, collisions between battery packs can damage the batteries, and in severe cases, can even lead to spontaneous combustion.

[0004] Traditionally, battery packs are assembled by wrapping multiple battery blocks in an insulating casing. While this method can improve the overall heat resistance of the battery pack and ensure its integrity, the battery blocks themselves generate heat, and the heat generated by a battery pack composed of multiple closely connected battery blocks increases, thus affecting the overall operation of the battery pack. Furthermore, because the multiple battery blocks are tightly connected, collisions between the battery blocks when subjected to high-frequency vibrations can still cause damage to the battery pack.

[0005] Therefore, we propose a battery pack with a higher safety factor during drilling activities. Utility Model Content

[0023] The technical solution of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, these are merely corresponding to the drawings of the present invention and are for the convenience of describing the present invention. They do not indicate or imply that the devices or components referred to must have a specific direction.

[0024] Combined with attachment Figure 1-2 The battery device for oil drilling activities includes a heat-resistant sleeve 1, a battery pack 2, a positive terminal plug 3 and a negative terminal plug 4. The positive terminal plug 3 and the negative terminal plug 4 are respectively provided at both ends of the heat-resistant sleeve 1. In particular, the heat-resistant sleeve 1 is made of glass fiber, wherein the glass fiber material can withstand higher temperatures, which makes the glass fiber sleeve 1 very suitable for use in high-temperature environments. In addition, compared with other types of sleeve 1 materials, the glass fiber sleeve 1 has higher mechanical strength, is not easy to deform or damage, and can withstand certain external forces; and compared with the sleeve 1 made of metal material, the glass fiber sleeve 1 is lighter and easier to carry and install; and the glass fiber itself is not easy to burn, and its flame retardant properties can be improved by adding flame retardants, which is very important for applications requiring fire safety.

[0025] The battery pack 2 is located within the heat-resistant sleeve 1, and the positive pin of the battery pack 2 is electrically plugged into the positive terminal plug 3, and the negative pin of the battery pack 2 is electrically plugged into the negative terminal plug 4. Since the positive terminal plug 3 and the negative terminal plug 4 are plug-connected to the corresponding ends of the battery pack 2, and the plug-in portions of the three can transmit power, the battery pack 2 can be clamped, thereby fixing the position of the battery pack 2, preventing the battery pack 2 from shaking in the flame-retardant sleeve 1 due to high-frequency vibration, preventing the battery pack 2 from being damaged by bumps, and not affecting the power supply of the battery pack 2 to various components in the detection element.

[0026] It should be noted that the positive terminal plug 3 and the negative terminal plug 4 are both fastened to the corresponding ends of the thermal sleeve 1 by screws, thereby maintaining a stable clamping of the battery pack 2 in the thermal sleeve 1.

[0027] The positive end plug 3 is electrically connected to the external plug 5, and the negative end plug 4 is electrically connected to the external socket 6, wherein the external plug 5 and the external socket 6 are components in the detection element, that is, the positive end plug 3 and the negative end plug 4 are both electrically connected to the detection element.

[0028] Example 2 is:

[0029] Based on Example 1, the structure of the battery pack 2 is further defined, wherein shock-absorbing washers 7 are provided at both ends of the battery pack 2 to provide a buffer between the battery pack 2 and the positive and negative terminal plugs 4, thereby ensuring the safety of the entire battery pack 2. In addition, the battery pack 2 is composed of a plurality of battery blocks 21 connected in series, and the plurality of battery blocks 21 are located in the same straight line. The plurality of battery blocks 21 are connected in series using a "U"-shaped lead double-sided welding method, thereby improving the reliability of the welding of the battery pack 2.

[0030] As needed, shock-absorbing washers 7 are provided between adjacent battery blocks 21 for buffering between the battery blocks 21 and for protection. In addition, high-temperature resistant silicone is filled between the battery pack 2 and the inner wall of the heat-resistant sleeve 1, that is, the high-temperature resistant silicone is not only attached to the outside of the battery pack 2, but also penetrates into the gaps between the multiple battery blocks 21, so as to maintain the firm installation of the battery pack 2 in the heat-resistant sleeve 1 and the integrity of the battery pack 2. The high-temperature resistant silicone can also serve as a second layer of thermal insulation protection for the battery pack 2, so that the battery pack 2 can run more smoothly in a high-temperature environment. In addition, due to the insulating properties of the silicone, it will not interfere with the circuit connection between the battery blocks 21.

[0031] Example 3 is:

[0032] On the basis of Example 1, the circuit structure of the battery pack 2 is further limited, wherein each of the battery blocks 21 is connected in parallel with a protection diode 8 , and the positive electrode of each battery block 21 is provided with a chip fuse 9 .

[0033] In addition, the positive electrode pin of the battery pack 2 is sequentially connected in series with an anti-reverse connection diode 10 and a fuse 11 to protect the battery pack 2.

[0034] It should be noted that under oil drilling conditions, the requirements for battery pack 2 are: rated capacity ≥ 24.0Ah, maximum operating current 200mA, cut-off voltage 20V, operating temperature: -40℃~+150℃;

[0035] Therefore, an embodiment of a battery pack 2 is selected here: a high-temperature resistant Li / SOCl2 system is selected, and the standard voltage of the Li / SOCl2 system battery is: 3.6V, the operating temperature range is wide: -40℃~+150℃, and the battery has a high specific energy; but to meet the requirements of open circuit voltage ≥28.8V, operating voltage ≥26.0V, and rated capacity ≥24.0Ah, the number of single battery blocks 21 connected in series must be ≥8. Therefore, after selecting 8 single battery cells in series, the operating voltage platform of the battery pack 2 under a load of 200 mA is about 26V~28.8V, which meets the requirements for use in oil drilling.

[0036] Furthermore, based on the battery pack 2's dimensions and actual testing, the selected single cell size is Φ34.0 x H127.0, within the given dimensions of the battery pack 2 enclosure. To ensure safety, each single cell is equipped with an integrated fuse protection circuit board on the outside of the upper cover. This circuit board consists of a protection diode 8 and a chip fuse 9, ensuring reliable and stable operation even under high-temperature conditions.
