Description

Technical Field

[0001] This utility model relates to the field of mining electrical equipment technology, specifically a compact and efficient heat dissipation structure for a mine explosion-proof mobile substation. Background Technology

[0002] In mining production activities such as coal mining, the underground environment of coal mines is complex and contains flammable and explosive substances such as gas and coal dust. Therefore, the explosion-proof performance requirements for electrical equipment are extremely high. The explosion-proof mobile substation for mining is designed to meet this special need. It can convert high-voltage electrical energy into low-voltage electrical energy suitable for various underground equipment, providing stable and reliable power support for key equipment such as coal mining machines, tunneling machines, and conveyors. It is one of the core power equipment to ensure the safe production and efficient operation of coal mines.

[0003] With the continuous advancement of coal mining technology and the increase in mining depth, the power of underground equipment is constantly increasing. At the same time, the continuous operation of underground equipment for a long time will cause a large amount of heat to be generated inside the mobile substation. If this heat cannot be dissipated in a timely and effective manner, the temperature inside the substation will rise sharply, thereby affecting the performance and lifespan of the electrical equipment.

[0004] Traditional explosion-proof mobile substations for mining typically employ natural heat dissipation, which relies mainly on heat exchange between the substation's outer shell and the surrounding environment. However, due to poor air circulation underground and the relatively high ambient temperature, the effectiveness of natural heat dissipation is quite limited.

[0005] Therefore, in order to address the above problems, the applicant needs to design a compact and efficient heat dissipation structure for a mine explosion-proof mobile substation. Utility Model Content

[0006] The purpose of this invention is to provide a compact and efficient heat dissipation structure for a mine explosion-proof mobile substation, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a compact and efficient heat dissipation structure for a mine explosion-proof mobile substation, including a support base, with casters fixedly mounted on the bottom surface of the support base, and the substation body mounted on the top surface of the support base.

[0008] It also includes: a heat dissipation mechanism disposed above the support base, which is used to reduce the ambient temperature around the main body of the substation. The heat dissipation mechanism includes a buffer box fixedly connected to the support base, and a connecting pipe is fixedly connected to one side of the buffer box. A heat dissipation pipe is fixedly connected to the end of the connecting pipe away from the buffer box, and an extension pipe is fixedly connected to the end of the heat dissipation pipe away from the connecting pipe. A water pump is fixedly connected to the end of the extension pipe away from the heat dissipation pipe. A circulation pipe is fixedly connected to the outlet of the water pump, and the circulation pipe is fixedly connected to the buffer box. An auxiliary component is disposed on the buffer box, and the auxiliary component is used to accelerate airflow.

[0009] Furthermore, a stabilizing base is fixedly installed on the bottom surface of the water pump, and the stabilizing base is fixedly connected to the support base.

[0010] Furthermore, a fixing frame is provided on the heat dissipation pipe, and the fixing frame is fixedly connected to the substation body.

[0011] Furthermore, the buffer box is fixedly connected to a water inlet pipe, and the water inlet pipe is connected to an external water source.

[0012] Furthermore, the auxiliary component includes a mounting plate fixedly connected to the buffer box, a support frame fixedly mounted on the mounting plate, and a cooling fan mounted on the support frame.

[0013] Furthermore, a protective frame is provided on the outside of the cooling fan, and the protective frame is fixedly connected to the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the compact and efficient heat dissipation structure of this mine explosion-proof mobile substation facilitates the cooling of the ambient temperature around the substation body, thereby improving the service life of the substation body. The specific details are as follows:

[0015] The compact and efficient heat dissipation structure of this explosion-proof mobile substation for mining uses a water pump to drive coolant out of the buffer tank, through the connecting pipes, heat dissipation pipes, and extension pipes, before being pumped back to the circulation pipes and back to the buffer tank, forming a closed loop. During this process, the heat dissipation pipes, as the core heat exchange components, continuously transfer the heat generated inside the substation to the flowing coolant. At the same time, the cooling fans accelerate the airflow around the main body of the substation, forcing convection to quickly dissipate the heat inside the main body of the substation into the environment, thereby continuously cooling the main body of the substation and ultimately achieving the purpose of compact, efficient, and active heat dissipation for the mobile substation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, this utility model discloses a compact and efficient heat dissipation structure for a mine explosion-proof mobile substation. It includes a support base 1, with casters 10 fixedly mounted on the bottom surface of the support base 1 and a substation body 11 mounted on the top surface of the support base 1. It also includes a heat dissipation mechanism 2 mounted above the support base 1, used to reduce the ambient temperature around the substation body 11. The heat dissipation mechanism 2 includes a buffer box 20 fixedly connected to the support base 1, with a connecting pipe 21 fixedly connected to one side of the buffer box 20. A heat dissipation pipe 22 is fixedly connected to the end of the connecting pipe 21 away from the buffer box 20, and an extension pipe 23 is fixedly connected to the end of the heat dissipation pipe 22 away from the connecting pipe 21. A water pump 24 is fixedly connected to the end of the extension pipe 23 away from the heat dissipation pipe 22. A circulation pipe 25 is fixedly connected to the outlet of the water pump 24 and is fixedly connected to the buffer box 20. An auxiliary component 29 is mounted on the buffer box 20 to accelerate airflow.

[0023] A stabilizing base 26 is fixedly installed on the bottom surface of the water pump 24, and the stabilizing base 26 is fixedly connected to the support base 1. The stabilizing base 26 firmly fixes the water pump 24 on the support base 1, which significantly improves the operating stability of the water pump 24 in the complex, potentially bumpy or vibrating environment underground, prevents the water pump 24 from shifting or being damaged due to vibration, thereby ensuring the reliability and continuity of the coolant circulation of the entire heat dissipation system, and indirectly improving the heat dissipation efficiency and service life of the substation.

[0024] A fixing frame 27 is provided on the heat dissipation pipe 22, and the fixing frame 27 is fixedly connected to the substation body 11. The fixing frame 27 firmly fixes the heat dissipation pipe 22 to the substation body 11, effectively preventing the heat dissipation pipe 22 from being displaced, deformed or loosened due to vibration or external force during equipment movement or operation. This ensures the preset relative position and contact effect between the heat dissipation pipe 22 and the substation body 11, and guarantees the stability of the heat transfer path and the heat dissipation efficiency.

[0025] The buffer tank 20 is fixedly connected to a water inlet pipe 28, which is connected to an external water source. The water inlet pipe 28 allows the buffer tank 20 to be easily connected to an external water source for coolant replenishment or replacement. This is crucial for maintaining the continuous and efficient operation of the heat dissipation system in the high-temperature and high-heat-dissipation environment underground. It solves the problem of coolant efficiency decline due to continuous heat absorption and temperature rise, ensuring that the system can provide low-temperature cooling medium for a long time, and significantly improving the continuous heat dissipation capacity and adaptability of the heat dissipation system.

[0026] The auxiliary component 29 includes a mounting plate 290 fixedly connected to the buffer box 20. A support frame 291 is fixedly mounted on the mounting plate 290, and a cooling fan 292 is mounted on the support frame 291. The cooling fan 292 accelerates the airflow at the buffer box 20. Through fan convection, the heat exchange rate between the surface of the substation body 11 and the surrounding air is greatly enhanced, effectively reducing the ambient temperature of the substation.

[0027] A protective frame 293 is provided on the outside of the cooling fan 292, and the protective frame 293 is fixedly connected to the support frame 291. The protective frame 293 provides physical protection for the cooling fan 292. In the harsh environment of underground coal mines, which are full of coal dust, may have small particles flying, or have the risk of accidental contact, the protective frame 293 can effectively prevent foreign objects from entering the fan blades and causing jamming, damage, or mechanical sparks, while protecting personnel safety.

[0028] Working principle: When using the compact and efficient heat dissipation structure of this mine explosion-proof mobile substation, the water pump 24 drives the coolant to flow out from the buffer tank 20, and then flows through the connecting pipe 21, the heat dissipation pipe 22 and the extension pipe 23 in sequence. After that, it is pumped back to the circulation pipe 25 and returned to the buffer tank 20, forming a closed loop. During this process, the heat dissipation pipe 22, as the core heat exchange component, continuously transfers the heat generated inside the substation to the flowing coolant. At the same time, the cooling fan 292 accelerates the air flow around the main body 11 of the substation, and the forced convection quickly dissipates the heat inside the main body 11 of the substation into the environment, thereby continuously cooling the main body 11 of the substation, and finally achieving the purpose of compact, efficient and active heat dissipation of the mobile substation.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
