Problems solved by technology

However, because the working cycle of the explosion-proof fan is very long, it will cause a high temperature on the surface of the shell, which is not conducive to the safe use of the explosion-proof fan, and the existing convenient fans do not have a mobile function. Due to the large volume of the explosion-proof fan, it will cause It is difficult for the explosion-proof fan to adapt to different ground environments for transfer, and it is convenient for the fan to vibrate during the working process, which will cause the shell to emit a lot of noise and cause noise pollution to the surrounding environment

Embodiment 1

[0037] see Figure 1-8 According to an embodiment of the present invention, a telescopic explosion-proof fan that is convenient to move and is applicable to various ground environments includes a base plate 1, and first electric telescopic rods 2 are fixedly embedded in the four corners of the base plate 1. The bottom of the first electric telescopic rod 2 is fixed with a fixed plate 3, and the fixed plate 3 is fixed with a first sliding tube 4 near the four corners, and a first sliding rod is installed in the first sliding tube 4. 5. The outer wall fixed sleeve at the lower end of the first sliding rod 5 is provided with a fixed ring 6, the outer wall fixed sleeve of the fixed ring 6 is provided with a first sealing ring 7, and the sliding sleeve near the lower end outer wall of the first sliding rod 5 is provided with a second Two sealing rings 8, the outer wall of the second sealing ring 8 is fixedly sleeved with a movable ring 9, the outer wall of the movable ring 9 is fix...

Embodiment 2

[0040] see figure 1 with 8 , for the fixed plate 3, the bottom of the fixed plate 3 is fixed with non-slip rubber pads; for the fan blade mounting seat 17, the end of the fan blade mounting seat 17 away from the motor 16 is arranged in a tapered structure; As for the heat dissipation pipe 21 , the heat dissipation pipe 21 is disposed in the rectangular frame 20 in a serpentine shape.

[0041] Through the above solution of the present invention, the anti-slip rubber pad can increase the anti-skid performance of the lower end of the fixing plate 3, and the one end of the fan blade mounting seat 17 is arranged in a tapered structure, which can effectively reduce the resistance of the fan blade mounting seat 17 to the airflow.

Embodiment 3

[0043] see figure 1 with 3 , for the box door 29, a box lock is installed on the side of the box door 29 away from the hinge; for the fan housing 15, a temperature sensor 50 is fixed on the inner wall of one end of the fan housing 15, A display screen 51 is fixedly embedded on the outer wall of the box door 29 , and both the temperature sensor 50 and the display screen 51 are electrically connected to the controller 27 .

[0044] Through the above scheme of the present invention, the temperature sensor 50 can be used to detect the temperature of the fan housing 15, and the detected temperature information can be sent to the controller 27 for display on the display screen 51, and the controller 27 can intelligently The operating power of the control circulation pump 19 and the cooling fan 23.

Abstract

The invention discloses a telescopic explosion-proof fan convenient to move and suitable for various ground environments, the telescopic explosion-proof fan comprises a bottom plate, first electric telescopic rods are fixedly embedded in the four corners of the bottom plate correspondingly, fixing plates are fixedly arranged below the first electric telescopic rods correspondingly, first sliding cylinders are fixedly arranged at the positions, close to the four corners, of the fixing plates correspondingly, first sliding rods are slidably arranged in the first sliding cylinders, and the outerwalls of the lower ends of the first sliding rods are fixedly sleeved with fixing rings. The telescopic explosion-proof fan has the beneficial effects that a fan shell can be effectively cooled, so that the explosion-proof fan can safely operate for a long time; moving wheels and a crawler belt are arranged to facilitate movement of the fan, and the explosion-proof fan can be switched between thecrawler belt and the moving wheels, so that the explosion-proof fan can adapt to different ground environments to be transferred; and effective damping can be conducted in the moving process and the fan working process, and therefore noise can be lowered, and the fan can be protected.

Description

technical field [0001] The invention relates to the field of explosion-proof blowers, in particular to a telescopic explosion-proof blower that is easy to move and applicable to various ground environments. Background technique [0002] Fan is the customary abbreviation for gas compression and gas delivery machinery in my country. Gas compression and gas delivery machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports the gas out. Explosion-proof fans are used in places where the concentration of combustible gas is high and ventilation is required, such as underground coal mines, boiler rooms, etc. However, because the working cycle of the explosion-proof fan is very long, it will cause a high temperature on the surface of the shell, which is not conducive to the safe use of the explosion-proof fan, and the existing convenient fans do not have a mobile function. Due to the large volume of the explosion-proof...
