Description

Technical Field

[0001] The utility model relates to the field of underground iron ore mining, in particular to an underground ventilation device. Background Art

[0002] Underground iron ore mining is the process of extracting iron ore from underground through underground tunnels or mines. The air below the mine may be relatively thin and mixed with harmful substances. In order to ensure the safety of the operation, underground ventilation devices are used to purify the underground air. When some underground ventilation devices are in use, in order to prevent dust from the outside air from entering the mine, filter plates are installed inside the device to improve the freshness of the air. However, the filter plates may become clogged after long-term use, thereby reducing the ventilation effect. Most filter plates are fixed to the inside of the device by multiple sets of bolts, which makes disassembly and assembly too troublesome, reducing work efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an underground ventilation device, including a ventilation device 1, which is a prior art. It accelerates the air flow by rotating the fan, thereby improving the air quality in the mine. A through groove 5 is provided at the front end of the right surface of the ventilation device 1. A filter plate 2 is slidably penetrated at the front end of the upper surface of the ventilation device 1. The filter plate 2 can filter external dust to prevent dust from entering the mine and causing damage to the workers' bodies. A through groove 2 6 is provided on the right side of the upper surface of the filter plate 2. A cleaning Component 3, a disassembly component 4 is provided on the inner wall at the top end of the filter plate 2, and the cleaning component 3 includes a slider 37, which is slidably connected to the inner wall of the through groove 5, and a spring 38 is fixedly connected to the front surface of the slider 37. The spring 38 always pulls the slider 37 forward by its own elasticity to ensure that the push rod 39 is always inserted in the hole of the filter plate 2 without pushing the connecting block 33, so that the inner wall of the hole of the filter plate 2 can be cleaned, thereby improving the air quality. The front end of the spring 38 is fixedly connected to the inner wall of the through groove 5, and the right surface of the slider 37 is fixedly connected to the connecting block 33.

[0032] Reference Figure 2 - Figure 3 The disassembly and assembly component 4 includes a push plate 43, which is convenient for the staff to push the card block 42 through it. The push plate 43 is slidably connected to the through groove 2 6, and the card block 42 is fixedly connected to the lower surface of the push plate 43. The card block 42 penetrates and slides to the right surface of the top of the filter plate 2.

[0033] Reference Figure 1 - Figure 2The cleaning component 3 also includes a reciprocating electric telescopic rod 31. The reciprocating electric telescopic rod 31 is a prior art. The reciprocating electric telescopic rod 31 can realize reciprocating or back and forth movement, so that the cleaning component 3 can repeatedly clean the filter plate 2 to improve the cleaning effect. The reciprocating electric telescopic rod 31 is fixedly connected to the front end of the upper surface of the ventilation device 1. The lower surface of the reciprocating electric telescopic rod 31 is fixedly connected with an extrusion block 32. The rear surface of the extrusion block 32 contacts the upper surface of the connecting block 33. The slider 37 is provided with multiple groups and connected through the connecting block 33 to ensure the stability of the movement of the leak plate 36. The bottom end of the front surface of the reciprocating electric telescopic rod 31 is fixedly connected with a U-shaped connecting rod 34. The left end of the U-shaped connecting rod 34 A scraper 35 is fixedly connected to the rear surface, and the bottom of the connecting block 33 exceeds the bottom of the ventilation device 1, ensuring that when the reciprocating electric telescopic rod 31 is started, the extrusion block 32 does not separate from the front surface of the connecting block 33, and the scraper 35 can leak out from the inner wall of the front end of the ventilation device 1, ensuring that the dust in the middle part where the scraper 35 contacts the filter plate 2 can leak out, thereby improving practicality. The scraper 35 is slidably connected to the inner wall of the front end of the ventilation device 1, the rear surface of the extrusion block 32 is set as an inclined surface, and the upper surface of the connecting block 33 is set as an inclined surface. The inclined surface of the extrusion block 32 and the inclined surface of the connecting block 33 can ensure that the extrusion block 32 can smoothly push the connecting block 33 to move when it moves.

[0034] Reference Figure 2 , Figure 4 A leakage plate 36 is fixedly connected to the left surface of the slider 37. A plurality of holes are arranged on the surface of the leakage plate 36, and the holes are offset from the holes of the filter plate 2 to ensure that the air can circulate smoothly. The leakage plate 36 is slidably connected to the inner wall of the ventilation device 1 near the rear side of the filter plate 2. A plurality of groups of push rods 39 are fixedly connected to the front surface of the leakage plate 36. The plurality of groups of push rods 39 correspond one-to-one to the holes arranged on the filter plate 2 to ensure the cleaning effect. The push rods 39 contact the inner wall of the filter plate 2.

[0035] Reference Figure 2 - Figure 3 The left surface of the block 42 is fixedly connected with a spring 2 44 . The spring 2 44 itself has a certain elasticity and always pushes the block 42 to move to the right to ensure the stability of the filter plate 2 during installation. The left end of the spring 2 44 is fixedly connected to the inner wall of the top end of the filter plate 2 .

[0036] Reference Figure 1 , Figure 3 The disassembly and assembly component 4 also includes a fixed block 41, which is fixedly connected to the front end of the upper surface of the ventilation equipment 1 near the left side of the reciprocating electric telescopic rod 31, and the clamping block 42 contacts the inner wall of the fixed block 41. The clamping block 42 is adapted to the inner wall of the fixed block 41 to ensure the stability of its connection. The clamping block 42 is set to a trapezoidal shape, and the right surface is set to an inclined surface. The set inclined surface can improve the installation efficiency.

[0037] Working principle: When the ventilation equipment 1 is in use and the filter plate 2 does not need to be cleaned, the reciprocating electric telescopic rod 31 can be started to move the extrusion block 32 to the bottom of the ventilation equipment 1. At this time, the extrusion block 32 will push itself backward along the inclined surface of the connecting block 33 through its own inclined surface, and the connecting block 33 will drive the slider 37 to slide on the inner wall of the through groove 5. At the same time, the slider 37 will stretch the spring 38, and the slider 37 will drive the leak plate 36 to move. The leak plate 36 will drive the top rod 39 to move, so that it will be separated from the inner wall of the hole of the filter plate 2, so as not to affect the ventilation effect of the ventilation equipment 1.

[0038] If the filter plate 2 is found to be clogged and needs to be cleaned, it is only necessary to start the reciprocating electric telescopic rod 31, which will drive the scraper 35 to move through the U-shaped connecting rod 34, so that the scraper 35 moves to the top of the ventilation device 1. At this time, the inclined surface of the extrusion block 32 will contact the inclined surface of the connecting block 33, and the slider 37 will move forward through the elasticity of the spring 1 38. The slider 37 will drive the leak plate 36 and the push rod 39 to move forward at the same time, so that the push rod 39 is inserted into the hole of the filter plate 2 to avoid clogging of the filter plate 2. The reciprocating electric telescopic rod 31 can be repeatedly extended and retracted to achieve the effect of rapid cleaning, thereby improving practicality.

[0039] When the filter plate 2 needs to be disassembled, it is only necessary to push the push plate 43, and the push plate 43 will drive the block 42 to move until the block 42 is separated from the inner wall of the fixed block 41. At this time, the filter plate 2 can be pulled out from the inner wall of the ventilation and air exchange device 1. When installing, it is only necessary to insert the filter plate 2 into the inner wall of the ventilation and air exchange device 1 until the block 42 contacts the fixed block 41. At this time, the fixed block 41 will push it to move along the inclined surface of the block 42, and the block 42 will squeeze the spring 2 44 until the block 42 completely overlaps with the inner wall of the fixed block 41. At this time, the spring 2 44 will push the block 42 to move in the opposite direction through its own elasticity, so that the block 42 is inserted into the inner wall of the fixed block 41, which is quick and convenient, and improves work efficiency.
