Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a modular and easy-to-maintain ventilator casing. Background Art

[0002] A ventilator is a mechanical device that uses mechanical energy to drive gas flow, thereby achieving ventilation, cooling and dehumidification, or removing harmful gases. Therefore, it is widely used in industrial plants, mines, tunnels, ships, civil buildings and other places to ensure air circulation and improve the working or living environment.

[0003] A ventilator generally consists of a casing, a base, a motor, fan blades and other components. The motor of some existing ventilators is fixedly mounted on a bracket inside the casing, and the bracket is fixedly mounted inside the casing. Since the casing of the ventilator has a certain depth, when maintaining the motor, the motor needs to be removed from the bracket. At the same time, since the motor itself has a certain weight, it is necessary to use external auxiliary devices such as lifting equipment to lift the motor out of the bracket in the casing before the motor can be removed and maintained. Therefore, this installation method of the motor brings certain inconveniences to the later maintenance, especially in an installation environment with a small space, where the motor cannot be easily removed and maintained with the help of external equipment.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 7 As shown, the utility model provides a modular and easy-to-maintain ventilator casing, including a fan casing 1, a bottom shell 2 is fixedly installed on the bottom of the fan casing 1, and multiple bases 3 are movably installed on the bottom of the bottom shell 2, and multiple guide rails 4 are fixedly installed on the inner side of the fan casing 1. A supporting plate 5 is also provided in the fan casing 1, and multiple base plates 14 are fixedly installed on the bottom of the supporting plate 5, and the supporting plate 5 is movably installed in the fan casing 1 through the base plate 14. A motor 6 is fixedly installed on the top of the supporting plate 5, and multiple fan blades 7 are fixedly installed on the output end of the motor 6. The supporting plate 5 located between the two base plates 14 is movably installed with a first support column 8, a limiting rod 9 is movably installed in the first support column 8, and a second support column 10 is movably installed at the bottom of the first support column 8.

[0027] like Figure 3-Figure 6The bottom of the support plate 5 between the two bottom plates 14 is fixedly mounted with two axle seats 12, and the support plate 5 between the two axle seats 12 is provided with a first limiting slot 13. Based on this, the arrangement of the two axle seats 12 can provide installation adjustment for the first support column 8, and the opening of the first limiting slot 13 can cooperate with the limiting rod 9 to achieve angle fixation of the first support column 8.

[0028] like Figure 5 、 Figure 7 As shown, two fixed shafts 17 are fixedly installed on the outside of the first support column 8, a telescopic groove 18 is opened on the top of the first support column 8, a right-hand screw groove 19 is opened at the bottom of the first support column 8, and a through hole 20 is also opened on the first support column 8 between the telescopic groove 18 and the right-hand screw groove 19. The bottom of the limiting rod 9 is provided with a left-hand screw groove 21 and is inserted into the telescopic groove 18. The first support column 8 is rotatably installed between the two shaft seats 12 through the two fixed shafts 17, and the top of the second support column 10 is fixedly installed with a right-hand screw 2 2. A left-handed screw rod 23 is fixedly installed on the top of the right-handed screw rod 22. The right-handed screw rod 22 is threadedly connected to the right-handed screw groove 19, and the top of the left-handed screw rod 23 passes through the through hole 20 and is threadedly connected to the left-handed screw groove 21. Based on this, the right-handed screw rod 22 is threadedly connected to the right-handed screw groove 19, and the top of the left-handed screw rod 23 is threadedly connected to the left-handed screw groove 21.

When the motor 6 is removed from the fan housing 1 for maintenance, the limit screws 11 on the front sides of the three guide rails 4 can be rotated outward respectively, so that one end of the three limit screws 11 is respectively selected from the screw groove at the bottom of the corresponding bottom plate 14, and the motor 6 can be pulled outward. Then, the motor 6 drives the support plate 5 to move, and the support plate 5 can drive the three bottom plates 14 to slide out on the corresponding guide rails 4 through the sliding groove 15 at the bottom, and the sliding out process of the bottom plate 14 is limited by the cooperation of the limit screw 11 and the second limit groove 16. Subsequently, the two first support columns 8 at the bottom of the support plate 5 are pulled downward respectively. The first support column 8 can be rotated between the corresponding two shaft seats 12 with the two fixed shafts 17 as the axis. Then, the two first support columns 8 are rotated separately, so that the second support column 10 drives the right-hand screw 22 to rotate downward in the right-hand screw groove 19. At the same time, the right-hand screw 22 drives the top of the left-hand screw 23 to rotate in the left-hand screw groove 21 and move the limit rod 9 upward in the telescopic groove 18, so that the bottom of the second support column 10 can be pressed against the ground to cooperate with the first support column 8 to support one side of the support plate 5. At the same time, the top of the limit rod 9 is inserted into the first limit groove 13 to limit the angle between the first support column 8 and the limit rod 9, thereby facilitating the disassembly and maintenance of the motor 6.
