[0019] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0020] Reference Figure 1 - Figure 4, an industrial instrument protective cover, comprising a protective cover 1, the front of the protective cover 1 is fixedly connected with an air inlet pipe 6, the upper surface of the protective cover 1 is fixedly connected with a ventilation pipe 3, the interior of the ventilation pipe 3 is provided with a fan blade 8, a rotating motor 9 is provided above the protective cover 1, the output end of the rotating motor 9 power passes through the ventilation pipe 3 and is fixedly connected to the outer surface of the fan blade 8, the upper surface of the protective cover 1 is fixedly connected with a controller 10, the inner wall of the protective cover 1 is fixedly connected with telescopic springs 14 arranged at equal distances, and the ends of each group of telescopic springs 14 close to each other are fixedly connected with a fixing frame 13, The inner wall of the fixing frame 13 is fixedly connected with a protective cotton 15, through which the instrument can be fixed, and the soft material of the protective cotton 15 itself can be used to protect the instrument. At the same time, the elasticity of the telescopic spring 14 cooperates with the fixing frame 13 to support the protective cotton 15 and provide buffering when a collision occurs, thereby protecting the instrument. At the same time, the controller 10 refers to a main command device that controls the starting, speed regulation, braking and reversal of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit in a predetermined order.

[0021] Reference Figure 1 The left side of the protective cover 1 is movably hinged with an opening and closing door 4, and the left side of the opening and closing door 4 is fixedly connected with a handle 5. The protective cover 1 can be opened or closed by the opening and closing door 4, and the opening and closing door 4 can be conveniently opened or closed by using the handle 5.

[0022] Reference Figure 1 - Figure 2 The upper surface of the protective cover 1 is fixedly connected with a protective shell 2, and the protective shell 2 is sleeved on the outside of the rotating motor 9 and the controller 10. The protective shell 2 can protect the rotating motor 9 and the controller 10, thereby extending the service life of the equipment.

[0023] Reference Figure 2 A filter ring 11 is fixedly connected to one end of the air inlet pipe 6 away from the protective cover 1.
