Description

Technical Field

[0001] This utility model relates to the field of explosion-proof fan technology, specifically a high-pressure aluminum alloy explosion-proof fan. Background Technology

[0002] Explosion-proof fans are used in locations with high concentrations of flammable gases requiring ventilation, such as underground coal mines and boiler rooms. The manufacturing process of explosion-proof fans is specifically designed so that, under special circumstances, the rotating parts (fan impeller) will not generate sparks when rubbing against the casing, thus preventing the ignition of flammable gases and causing serious consequences. Currently, adjusting the angle of explosion-proof fans requires directly moving the fan itself. However, explosion-proof fans are typically fixed with bolts, so moving them necessitates disassembly and reassembly, making angle adjustment inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a high-pressure aluminum alloy explosion-proof fan to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a high-pressure aluminum alloy explosion-proof fan, including a base frame and an explosion-proof fan body. One end of the explosion-proof fan body is rotatably connected to the base frame via an end shaft. Two symmetrical arc-shaped guide members are installed on the side of the base frame away from the end shaft. The two arc-shaped guide members are located on the side of the explosion-proof fan body, and the center of the arc-shaped guide members is located on the end shaft. Each arc-shaped guide member includes an arc-shaped guide part and a sliding part. The sliding part is connected to the side wall of the explosion-proof fan body. The outer side of the arc-shaped guide part is provided with equally spaced positioning holes. The sliding part of the arc-shaped guide member is provided with a locking positioning member that matches the positioning holes.

[0005] The aforementioned components achieve the following effect: through the cooperation of the base frame, explosion-proof fan body, arc-shaped guide, and locking positioning components, convenient adjustment of the fan angle is realized. When the fan angle needs to be adjusted, simply loosen the locking positioning component, allowing the sliding part to slide along the arc-shaped guide, driving the explosion-proof fan body to rotate around the end shaft. Once the target angle is reached, the locking positioning component engages with the positioning hole to lock the angle. Compared to the traditional adjustment method that requires re-disassembling and reassembling bolts, this design eliminates the tedious disassembly and assembly process, achieves rapid angle adjustment, improves work efficiency, and avoids damage to the equipment caused by frequent disassembly and assembly.

[0006] Preferably, the arc-shaped guide part includes an arc-shaped guide frame fixed on the base frame, the positioning hole is disposed on the outer arc surface of the arc-shaped guide frame, the arc-shaped guide frame is provided with an arc-shaped groove, and the sliding part is located in the groove.

[0007] The aforementioned components achieve the following effects: the positioning holes on the outer arc surface of the arc-shaped guide frame cooperate with the locking positioning components to achieve angle locking, while the arc-shaped groove provides a precise sliding path for the sliding part. This structural design ensures that the explosion-proof fan body is strictly guided and constrained during rotation, avoiding shaking and offset during adjustment and ensuring the accuracy of angle adjustment.

[0008] Preferably, the sliding part includes a sliding column slidably disposed in the slot, one end of the sliding column is connected to the outer side wall of the explosion-proof fan body, a limiting ring that fits against the arc-shaped guide frame is fixed on the outer side of the sliding column, and the locking positioning member is fixed on the end side of the sliding column.

[0009] The effect achieved by the above components is that when the explosion-proof fan body rotates around the end shaft, the sliding column slides synchronously along the slot, and the limiting ring and the arc-shaped guide frame make close contact, thus avoiding shaking and deviation during the adjustment process.

[0010] Preferably, the locking and positioning component includes a side plate fixed to one side of the slide column, a pin slidably inserted into one side of the side plate, a handle block fixed to one end of the pin, a protruding ring fixed to the end of the pin away from the handle block, and a spring sleeved on the pin between the protruding ring and the side plate.

[0011] The effect achieved by the above components is as follows: the pin of the locking and positioning component always tends to be inserted into the positioning hole under the action of the spring. When the angle needs to be adjusted, the handle is pulled to disengage the pin from the positioning hole. After the adjustment is in place, the handle is released, and the spring force pushes the pin to re-insert into the corresponding positioning hole, thus achieving the purpose of quick locking.

[0012] Preferably, a base plate is fixed to one side of the base frame, and a telescopic sleeve is rotatably connected between the top of the base plate and the outer wall of the bottom end of the explosion-proof fan body.

[0013] The effect achieved by the above components is that the two ends of the telescopic sleeve are rotatably connected to the base plate and the explosion-proof fan body, respectively. When the fan angle is adjusted, the telescopic sleeve extends, retracts and rotates accordingly, providing additional support points for the fan and dispersing the vibration and impact force generated during the operation of the fan.

[0014] This utility model provides a high-pressure aluminum alloy explosion-proof fan through improvements, which has the following improvements and advantages compared with the prior art:

[0015] When the fan angle needs to be adjusted, this utility model only requires loosening the locking positioning piece, allowing the sliding part to slide along the arc-shaped guide part, driving the explosion-proof fan body to rotate around the end shaft. After reaching the target angle, the locking positioning piece locks in place by engaging with the positioning hole. Compared to the traditional adjustment method that requires reinstalling bolts, this design eliminates the tedious disassembly and assembly process, achieving the goal of rapid angle adjustment.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved high-pressure aluminum alloy explosion-proof fan. The technical solution of this utility model is as follows:

[0024] In embodiments of this utility model, such as Figures 1-3As shown, a high-pressure aluminum alloy explosion-proof fan includes a base frame 1 and an explosion-proof fan body 2. One end of the explosion-proof fan body 2 is rotatably connected to the base frame 1 via an end shaft. Two symmetrical arc-shaped guide members 5 are installed on the side of the base frame 1 away from the end shaft. The two arc-shaped guide members 5 are located on the side of the explosion-proof fan body 2, and the center of the arc-shaped guide members 5 is located on the end shaft. The arc-shaped guide member 5 includes an arc-shaped guide part and a sliding part. The arc-shaped guide part includes an arc-shaped guide frame 51 fixed on the base frame 1. A positioning hole 7 is provided on the outer arc surface of the arc-shaped guide frame 51. An arc-shaped slot 52 is opened on the arc-shaped guide frame 51, and the sliding part is located in the slot 52. The positioning hole 7 is opened on the outer arc surface of the arc-shaped guide frame 51. The hole 7 cooperates with the locking and positioning component 6 to achieve angle locking, while the arc-shaped slot 52 provides a precise sliding path for the sliding part. This structural design ensures that the explosion-proof fan body 2 is strictly guided and constrained during rotation. The sliding part includes a sliding column 53 that is slidably disposed in the slot 52. One end of the sliding column 53 is connected to the outer wall of the explosion-proof fan body 2. A limiting ring 54 that fits against the arc-shaped guide frame 51 is fixed on the outer side of the sliding column 53. The locking and positioning component 6 is fixed on the end side of the sliding column 53. When the explosion-proof fan body 2 rotates around the end axis, the sliding column 53 slides synchronously along the slot 52. The limiting ring 54 and the arc-shaped guide frame 51 fit together, avoiding shaking and offset during the adjustment process.

[0025] The sliding part is connected to the side wall of the explosion-proof fan body 2. The outer side of the arc-shaped guide part has evenly distributed positioning holes 7. The sliding part of the arc-shaped guide 5 is equipped with a locking positioning element 6 that matches the positioning holes 7. The locking positioning element 6 includes a side plate 61 fixed to one side of the sliding column 53. A pin 62 is slidably inserted into one side of the side plate 61. A handle block 63 is fixed to one end of the pin 62, and a protruding ring 64 is fixed to the end of the pin 62 away from the handle block 63. A spring 65 is sleeved on the pin 62, located between the protruding ring 64 and the side plate 61. Under the action of the spring 65, the pin 62 of the locking positioning element 6 always maintains its tendency to be inserted into the positioning hole 7. When the angle needs to be adjusted, pull the handle block 63 to disengage the pin 62 from the positioning hole 7. After adjustment, release the handle block 63, and the spring force of the spring 65 pushes the pin 62 back into the corresponding positioning hole 7 to achieve quick locking. A base plate 4 is fixed on one side of the base frame 1. A telescopic sleeve 3 is rotatably connected between the top of the base plate 4 and the bottom outer wall of the explosion-proof fan body 2. The two ends of the telescopic sleeve 3 are rotatably connected to the base plate 4 and the explosion-proof fan body 2, respectively. When the fan angle is adjusted, the telescopic sleeve 3 extends, retracts and rotates accordingly, providing an additional support point for the fan and dispersing the vibration and impact force generated during the operation of the fan.

[0026] The working principle of the high-pressure aluminum alloy explosion-proof fan provided by this utility model is as follows: When it is necessary to adjust the fan angle, simply pull the handle block 63 to disengage the pin 62 from the positioning hole 7, so that the sliding column 53 slides synchronously along the groove 52. The arc-shaped groove 52 provides a precise sliding path for the sliding part, driving the explosion-proof fan body 2 to rotate around the end shaft. After the adjustment is in place, release the handle block 63, and the elastic force of the spring 65 pushes the pin 62 to re-insert into the corresponding positioning hole 7, thus realizing the purpose of convenient adjustment of the fan angle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
