Description

Technical Field

[0001] This utility model relates to a battery structure, and more particularly to an explosion-proof battery suitable for dusty environments. Background Technology

[0002] The defense industry has always been a key area of ​​concern for safe production, especially the production of pyrotechnics, which has always been a high-risk industry. The slightest carelessness can lead to serious accidents that threaten the lives of personnel. The high-density testing of weapons and equipment in my country at present has also exacerbated the severity of the safety situation.

[0003] Currently, logistics and assembly work in hazardous locations still rely on manual labor, or can only meet the material handling and assembly needs of a single product model, failing to meet the flexibility requirements of current production lines. If guided vehicles could be used in military product production sites, these problems could be solved.

[0004] However, the ordinary guide vehicles used in the market cannot be used in dusty environments because their batteries (or battery packs) are not explosion-proof. This makes it impossible to use guide vehicles for logistics transfer in dangerous locations.

[0005] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0006] This invention addresses the aforementioned shortcomings of existing technologies by proposing an explosion-proof battery that is simple in structure, safe and reliable, easy to install and maintain. It overcomes the deficiencies of existing technologies and achieves the goal of reducing manpower and increasing efficiency in hazardous locations.

[0007] The technical solution of this utility model is: an explosion-proof battery suitable for dusty environments, characterized in that: the explosion-proof battery includes an explosion-proof housing 1, multiple battery packs 2 are arranged inside the explosion-proof housing 1, a fixing plate 3 is arranged inside the explosion-proof housing 1, the fixing plate 3 presses all the battery packs 2 tightly onto the bottom surface of the explosion-proof housing 1, a battery cavity 4 is located below the fixing plate 3, a cooling fan 5 is arranged at one end of the battery cavity 4, and an exhaust port is opened on the side wall of the explosion-proof housing 1 at the other end, and a flame arrester 6 is arranged at the exhaust port. Heat sinks 7 are arranged between the two sides of the battery packs 2 and the inner wall of the explosion-proof housing 1, simultaneously contacting both sides, and heat dissipation channels are formed inside the heat sinks 7. The explosion-proof housing 1 is fixedly connected to the top of the explosion-proof cover plate 8 by bolts. A sealing ring 9 is provided between the explosion-proof housing 1 and the explosion-proof cover plate 8. A wiring cavity 10 is formed between the fixing plate 3 and the explosion-proof cover plate 8. A wiring hole is provided on the side wall of the explosion-proof housing 1. An explosion-proof gland connector 11 is provided at the wire search control.

[0008] The battery pack 2 is a standard lead-acid battery pack.

[0009] Compared with the prior art, this utility model has the following advantages: This type of explosion-proof battery, suitable for dusty environments, features a simple structure, ingenious design, and rational layout. Addressing the issue of traditional batteries being unsuitable for dusty environments due to structural defects, it employs a unique structure. It uses an explosion-proof housing to protect the battery pack, and a fixing plate clamps all the battery packs inside the housing to prevent movement. Fans and heat sinks dissipate heat from the battery packs, and explosion-proof gland joints and flame arresters prevent internal flames or electrical sparks from spreading to the outside of the enclosure in case of an malfunction, thus achieving explosion-proof protection. This explosion-proof battery can provide power to guide vehicles in dusty environments. Furthermore, its manufacturing process is simple and cost-effective, making it highly advantageous and suitable for widespread application in this field, with a very promising market prospect.

[0012] Figure 3 This is a side view of an embodiment of the present utility model. Detailed Implementation

[0013] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 3 The diagram shows an explosion-proof battery suitable for dusty environments. It includes an explosion-proof housing 1, within which multiple battery packs 2 are housed. A fixing plate 3 is installed inside the explosion-proof housing 1, pressing all the battery packs 2 against the bottom surface of the housing 1. Below the fixing plate 3 is a battery cavity 4. A cooling fan 5 (directly mounted on the explosion-proof housing 1) is installed at one end of the battery cavity 4, while an exhaust vent is provided on the side wall of the explosion-proof housing 1 at the other end. A flame arrester 6 is installed at the exhaust vent. Heat sinks 7 are installed between the two sides of the battery packs 2 and the inner wall of the explosion-proof housing 1, simultaneously contacting both sides. The heat sinks 7 form heat dissipation channels within their interiors. The explosion-proof housing 1 is fixedly connected to the top of the explosion-proof cover plate 8 by bolts. A sealing ring 9 is provided between the explosion-proof housing 1 and the explosion-proof cover plate 8. A wiring cavity 10 is formed between the fixing plate 3 and the explosion-proof cover plate 8. A wiring hole is provided on the side wall of the explosion-proof housing 1. An explosion-proof gland connector 11 is provided at the wire search control.

[0014] The battery pack 2 is a standard lead-acid battery pack.

[0015] The working process of the explosion-proof battery suitable for dusty environments according to this embodiment of the utility model is as follows: First, all battery packs 2 are placed inside the explosion-proof housing 1. Then, the fixing plate 3 is connected inside the explosion-proof housing 1. At this time, the bottom surface of the fixing plate 3 is in contact with the top surface of all battery packs 2, that is, the fixing plate 3 presses them tightly against the bottom surface of the explosion-proof housing 1. After all the cables of all battery packs 2 pass through the through holes opened on the fixing plate 3, they are led out to the outside of the explosion-proof housing 1 through the explosion-proof gland connector 11. When this type of battery is working, all battery packs 2 work, outputting the electrical energy stored inside to the externally connected power supply equipment. When the battery pack 2 is working, it generates heat, which is transferred to the heat sink 7. The cooling fan 5 works, allowing the air in the battery chamber 4 to flow from one end of the cooling fan 5 to the other. During the airflow, it passes through the heat dissipation channel formed inside the heat sink 7 and carries away the heat from the heat sink 7. The hot air that has absorbed the heat is discharged through the exhaust port, thereby achieving the purpose of reducing the internal temperature of the explosion-proof housing 1. Since a flame arrester 6 is installed at the exhaust port, it can effectively prevent the flame or electric spark inside the explosion-proof housing 1 from spreading to the external environment when the battery pack 2 malfunctions.
