Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal mine electromechanical cooling technology, specifically a coal mine electromechanical cooling device. Background Technology
[0002] Large equipment used in coal mining, such as ventilation fans, air compressors, and hoists, all require high-power motors for operation. These large motors generate a lot of heat during operation. If this heat accumulates inside the coal mine machinery for a long time, it can accelerate the aging of internal parts. To reduce the impact of heat on the coal mine machinery, cooling devices are often installed on the outside of the machinery casing to accelerate heat dissipation.
[0003] Patent number CN219269409U relates to a coal mine electromechanical cooling device, comprising a base, a housing, and a water tank. The housing and water tank are fixedly connected to the top of the base, with the water tank located on one side of the housing. A water pump is fixedly connected to the top of the water tank, with an inlet pipe fixedly connected to the pump's input end, extending into the water tank. A delivery pipe is fixedly connected to the pump's output end. Two support plates are symmetrically fixedly connected to the bottom of the housing's inner wall, and electromechanical equipment is fixedly connected to the top of the two support plates. A heat dissipation pipe is fixedly connected to the outer side of the electromechanical equipment, with one end of the heat dissipation pipe near the delivery pipe fixedly connected to it, and the other end extending into the water tank. The beneficial effects of this invention are that the heat dissipation pipe achieves heat dissipation for the electromechanical equipment while simultaneously recycling water back into the water tank, reducing water waste. Furthermore, the two fans better facilitate heat dissipation for the electromechanical equipment, enhancing the cooling effect.
[0004] However, the aforementioned electromechanical cooling device for coal mines still has the following shortcomings:
[0005] Although the above-mentioned device can dissipate heat from electromechanical equipment through the combination of a fan and a dustproof mesh cover, the suction fan easily causes coal dust in the outside air to adhere and accumulate on the surface of the dustproof mesh cover. Over time, the surface of the dustproof mesh cover becomes blocked, making it difficult to achieve good air circulation and affecting the heat dissipation of the electromechanical equipment. Therefore, we propose a coal mine electromechanical cooling device. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model provides a coal mine electromechanical cooling device, which effectively solves the problem that although the existing device can dissipate heat from the electromechanical equipment through the cooperation of a fan and a dustproof net cover, the suction fan is very easy for coal dust in the outside air to adhere and accumulate on the surface of the dustproof net cover. Over time, the surface of the dustproof net cover is blocked, making it difficult to achieve good air circulation and affecting the heat dissipation of the electromechanical equipment.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a coal mine electromechanical cooling device, comprising a coal mine electromechanical placement box, a set of air inlet mechanisms symmetrically fitted on both sides of the coal mine electromechanical placement box, an auxiliary mechanism provided inside the set of air inlet mechanisms, an exhaust port provided on the inner side of the top of the coal mine electromechanical placement box, the auxiliary mechanism including a rotating shaft, the rotating shaft being movably mounted inside the coal mine electromechanical placement box, a motor connected to one end of the rotating shaft, a protective box being fitted around the motor, a set of driving gears symmetrically fixedly fitted on the surface of the rotating shaft, a driven gear being provided on the front side of the driving gears, a synchronous toothed belt being fitted around the driving gears and the driven gears on the front side, and an I-frame being fixedly inserted through the driven gears.
[0008] Preferably, the auxiliary mechanism further includes a suction fan blade assembly, which is screwed into the inside of the I-frame near the driven gear. A scraper is engaged inside the side of the I-frame away from the suction fan blade assembly, and the I-frame and the scraper are connected by bolts.
[0009] Preferably, the driving gear forms a rotating structure with the motor via a rotating shaft, and the synchronous toothed belt meshes with the driving gear and the driven gear respectively.
[0010] Preferably, the I-beam is movably engaged in the middle of the air inlet mechanism, and one side of the scraper inserted inside the I-beam is in contact with the outer surface of the air inlet mechanism.
[0011] Preferably, the air intake mechanism includes a limiting ring frame, on the side of the limiting ring frame near the outside of the coal mine electromechanical placement box a dust filter plate is fixedly fitted, and on the side of the limiting ring frame near the inside of the coal mine electromechanical placement box an activated carbon filter plate is fixedly fitted.
[0012] Preferably, the inner wall of the limiting ring frame is in contact with the outer wall of the small diameter portion of the I-beam frame, and the dust filter plate and activated carbon filter plate on the outer side of the limiting ring frame are fixedly embedded in the inner side of the surface of the coal mine electromechanical placement box.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By setting the motor to effectively drive the rotating shaft to rotate, a set of driving gears on the surface of the rotating shaft will rotate. At the same time, under the action of the synchronous tooth belt, the driven gear will follow the driving gear to rotate. The rotating driven gear will effectively drive the I-frame and the suction fan blade assembly and scraper on its side to rotate. The rotating suction fan blade assembly will accelerate the air circulation inside the coal mine electromechanical placement box, thereby improving the heat dissipation effect. At the same time, the rotating scraper will effectively scrape off the coal mine dust on the surface of the dust filter plate, reducing the possibility of dust filter plate clogging. The detachable suction fan blade assembly and scraper will facilitate subsequent maintenance and replacement.
[0015] 2. By setting up dust filter plates, coal dust from the outside air is prevented from entering the coal mine electromechanical storage box and damaging the coal mine electromechanical equipment. Activated carbon filter plates effectively adsorb moisture from the outside air, reducing the possibility of corrosion of the coal mine electromechanical equipment inside the storage box. The heat generated when the coal mine electromechanical equipment is working inside the storage box (auxiliary mechanisms are not in operation) can dry and regenerate the activated carbon in the activated carbon filter plates, maintaining the adsorption efficiency of the activated carbon filter plates.

[0024] Please see Figure 1-4A coal mine electromechanical cooling device includes a coal mine electromechanical placement box 1. A set of air inlet mechanisms 2 are symmetrically fitted on both sides of the coal mine electromechanical placement box 1. An auxiliary mechanism 3 is provided inside the set of air inlet mechanisms 2. An exhaust port 4 is provided on the inner side of the top of the coal mine electromechanical placement box 1. The auxiliary mechanism 3 includes a rotating shaft 301, which is movably mounted inside the coal mine electromechanical placement box 1. One end of the rotating shaft 301 is connected to a motor 302. A protective box 303 is fitted around the motor 302. A set of drive gears 304 are symmetrically fixedly fitted on the surface of the rotating shaft 301. A driven gear 305 is provided on the front side of the 04. A synchronous toothed belt 306 is sleeved on the outside of the driving gear 304 and the driven gear 305 on the front side. The driving gear 304 forms a rotating structure with the motor 302 through the rotating shaft 301. The synchronous toothed belt 306 meshes with the driving gear 304 and the driven gear 305 respectively. A I-frame 307 is fixedly inserted through the driven gear 305. The auxiliary mechanism 3 also includes a suction fan blade assembly 308, which is screwed into the I-frame 307 on the side near the driven gear 305. A scraper 309 is internally engaged on the side of the frame 307 away from the fan blade assembly 308. Furthermore, the frame 307 is movably engaged in the middle of the air intake mechanism 2. One side of the scraper 309 inserted inside the frame 307 is in contact with the outer surface of the air intake mechanism 2. The frame 307 and the scraper 309 are connected by bolts 310. A motor 302 effectively drives the rotating shaft 301 to rotate, thereby driving a set of drive gears 304 on the surface of the rotating shaft 301 to rotate. Simultaneously, driven gears are rotated by the synchronous belt 306. 305 follows the rotation of the drive gear 304. The rotating driven gear 305 effectively drives the frame 307 and its side suction fan blade assembly 308 and scraper 309 to rotate. The rotating suction fan blade assembly 308 accelerates the air circulation inside the coal mine electromechanical placement box 1, thereby improving the heat dissipation effect. At the same time, the rotating scraper 309 effectively scrapes off the coal mine dust on the surface of the dust filter plate 202, reducing the possibility of clogging of the dust filter plate 202. The detachability of the suction fan blade assembly 308 and scraper 309 facilitates subsequent maintenance and replacement.
[0025] The air intake mechanism 2 includes a limiting ring frame 201. A dust filter plate 202 is fixedly sleeved on the side of the limiting ring frame 201 near the outside of the coal mine electromechanical storage box 1, and an activated carbon filter plate 203 is fixedly sleeved on the side of the limiting ring frame 201 near the inside of the coal mine electromechanical storage box 1. The inner wall of the limiting ring frame 201 is in contact with a portion of the outer wall of the small-diameter section of the I-beam frame 307. The dust filter plate 202 and the activated carbon filter plate 203 on the outer side of the limiting ring frame 201 are fixedly embedded in the inner surface of the coal mine electromechanical storage box 1. By setting up a dust filter plate 202, coal mine dust from the outside air is prevented from entering the coal mine electromechanical storage box 1 and damaging the coal mine electromechanical equipment. By setting up an activated carbon filter plate 203, moisture in the outside air is effectively adsorbed, reducing the possibility of corrosion of the coal mine electromechanical equipment inside the coal mine electromechanical storage box 1. The heat generated when the coal mine electromechanical equipment inside the coal mine electromechanical storage box 1 is working (auxiliary mechanism 3 stops working) can dry and regenerate the activated carbon in the activated carbon filter plate 203, maintaining the adsorption efficiency of the activated carbon filter plate 203.
