[0051] The present embodiment provides a fan early warning and automatic switching device, which comprises a movable pallet cart 100, a first side channel fan 110, a second side channel fan 120, a total air inlet pipe 130, an air inlet and outlet system 200 and a control unit;

[0052] The first side channel fan 110 has an air inlet and an air outlet, and a first side channel fan air inlet pipe 211 is arranged at the air inlet, the middle part of the first side channel fan air inlet pipe 211 is connected with a first electric control switching device 213, the rear end of the first electric control switching device 213 is connected to the three-way pipe 217, and the three-way pipe 217 is connected to the total air inlet pipe 130.

[0053] The second side channel fan 120 has an air inlet and an air outlet, and a second side channel fan air inlet pipe 214 is arranged at the air inlet, the middle part of the second side channel fan air inlet pipe 214 is connected with a second electric control switching device 216, the rear end of the second electric control switching device 216 is connected to the three-way pipe 217, and the three-way pipe 217 is connected to the total air inlet pipe 130.

[0054] The total air inlet pipe 130 is provided with a wind pressure detection device 132 on the other side pipe relative to the three-way pipe 217.

[0055] The control unit receives the signal of the wind pressure detection device 132 and adjusts the switching of the first electric control switching device 213 and the second electric control switching device 216 according to the signal feedback of the wind pressure detection device 132, and the control unit comprises an alarm system 510.

[0056] Referring to Figure 1 , the base of the first side channel fan 110 and the second side channel fan 120 is installed on the surface of the movable pallet cart 100.

[0057] Referring to Figure 2 , the air inlet and outlet system 200 comprises the first electric control switching device 213, the first side channel fan air inlet pipe 211, the second electric control switching device 216 and the second side channel fan air inlet pipe 214.

[0058] In this embodiment, the fan early warning and automatic switching device includes: a movable pallet trolley 100, a first side duct fan 110, a second side duct fan 120, a main air inlet duct 130, an air inlet / outlet system 200, and a control unit. Both the first side duct fan 110 and the second side duct fan 120 have air inlets and air outlets. An electronic control switching device is connected to the middle of the air inlet duct. If a fault is detected in a side duct fan, the corresponding electronic control switching device of the first side duct fan 110 or the second side duct fan 120 switches accordingly to achieve work switching between the two side duct fans. That is, when one side duct fan fails, the other side duct fan will automatically start, ensuring normal production.

[0059] Meanwhile, the fan early warning and automatic switching device in this embodiment also includes an alarm system 510. When one of the fans fails, the alarm device can be triggered, displaying details of the specific problem and simultaneously sending the alarm information and code to a remote terminal / mobile client. Furthermore, when the motor temperature is high, both fans can operate simultaneously, enhancing the applicable environment. Pre-alarms are designed to detect parameters such as temperature, air pressure, lubrication, and cooling systems, allowing for early detection of equipment abnormalities and reducing potential hazards.

[0060] In the optional technical solution of this embodiment, the three-way pipe 217 is also provided with a pressure relief device 131.

[0061] It should be noted that in this embodiment, the rear end pipes of each side duct fan switching device are connected to the main air inlet pipe 130, and the rear end of the main air inlet pipe 130 is connected to the pressure relief device 131. To prevent excessive negative pressure in the pipe or blockage of the port pipe, resulting in no negative pressure entering the fan, this embodiment can detect the air pressure in the main air inlet pipe 130 through the air pressure detection device 132, and adjust the pressure relief device 131 by setting the working internal air pressure standard to ensure normal requirements.

[0062] In the optional technical solution of this embodiment, the air outlet of the first side duct fan 110 is provided with a first silencing device 212; the air outlet of the second side duct fan 120 is provided with a second silencing device 215.

[0063] It should be noted that, in this embodiment, when the side duct fan is working, the intake air volume is delivered to the interior of the corresponding side duct fan through the main air inlet pipe 130, and after working inside it, it is discharged from the air outlet. Therefore, in this embodiment, a silencer is provided at the air outlet to eliminate the air pressure exhaust noise generated by the side duct fan and avoid noise pollution to the environment.

[0064] like Figures 1-5 As shown, the working principle and process of the wind turbine early warning and automatic switching device in this embodiment are as follows:

[0065] The first side channel fan 110 and the second side channel fan 120 are installed on the movable pallet cart 100. When the first side channel fan 110 is working, the first electric control switching device 213 is in an open state, and the second electric control switching device 216 is in a closed state. When the first side channel fan 110 is detected to be in failure, the first electric control switching device 213 is closed, the second electric control switching device 216 corresponding to the second side channel fan 120 is opened, and the second side channel fan 120 starts to work normally. Conversely, when the second side channel fan 120 is working, the same is true.

[0066] When the above two side channel fans are working, the air volume sucked by the side channel fans is delivered to the inside of the corresponding side channel fan through the total air inlet pipe 130, and is discharged from the air outlet after working in the inside. The sound elimination device at the air outlet eliminates the air pressure generated by the side channel fan and eliminates the noise, so as to avoid noise pollution to the environment.

[0067] When working, the air pressure detection device 132 is installed at the rear end of the total air outlet pipe, which can detect the air pressure when the first side channel fan 110 and the second side channel fan 120 work respectively. When the air pressure detected by the air pressure detection device 132 is lower than the set minimum standard, the working side channel fan stops working, and another side channel fan will be switched to work through the touch screen control system 500 and the switching device. At the same time, the alarm system 510 flashes and emits sound, and the problem can be displayed through the touch screen control system 500, and the synchronous information will be sent to the mobile terminal or the monitoring computer in the form of information.

[0068] Referring to Figure 3 , Figure 4 In an optional technical solution of the embodiment, an adjustable bottom support 300 is arranged on the movable pallet cart 100, and the adjustable bottom support 300 is fixed on the movable pallet cart 100 through support positioning bolts 303.

The side channel fan is fixed on the limiting plate 301 through the fan positioning screw 307, and the limiting plate 301 can be adjusted in position through the tension limiting bolt 305.

[0071] Continuing to refer to Figure 3In an optional technical solution of the embodiment, the adjustable bottom support 300 further comprises a positioning plate 302, which positions the limiting plate 301 by pressing the limiting plate 301 through an adjusting positioning screw 304.

[0072] In an optional technical solution of the embodiment, the adjustable bottom support 300 further comprises a level for observing the horizontal state of the electrode during work and a transverse lifting screw 310 for adjusting the horizontal state of the adjustable bottom support 300; the level comprises a transverse level 309 and a longitudinal level 308.

[0073] It should be noted that due to different foundations, the working state of the motor cannot be guaranteed to be horizontal, and the horizontal state can be observed through the transverse level 309 and the longitudinal level 308. Meanwhile, the horizontal state can be adjusted by loosening the four support positioning screws 303 and adjusting the four transverse lifting screws 310, and then the position is fixed by the four support positioning screws 303 after the horizontal state is observed. The height can be adjusted by loosening the four tension limiting screws 305 and adjusting the four longitudinal lifting screws 306, and then the position is fixed by adjusting the tension limiting screws 305 after the horizontal state is observed. Finally, the motor is installed in a horizontal state.

[0074] In an optional technical solution of the embodiment, the fan early warning and automatic switching device further comprises a lubricating system; the lubricating system comprises a lubricating oil storage tank 320, a lubricating oil pipeline 321, and a lubricating oil injection hole 322.

[0075] During work, the first side channel fan 110 and the second side channel fan 120 need to ensure that the equipment can work continuously because of long-time work, and the internal structure of the equipment needs to be lubricated. Therefore, an automatic lubricating system is provided. When the working time of the first side channel fan 110 reaches the set time, the lubricating oil in the lubricating oil storage tank 320 is added to the inside of the first side channel fan 110 through the lubricating oil injection hole 322 from the lubricating oil pipeline 321 under the action of pressure. The addition amount and addition time can be set to ensure effective lubrication. The working of the second side channel fan 120 is the same.

[0076] Referring to Figure 5 In an optional technical solution of the embodiment, the first side channel fan 110 and the second side channel fan 120 are provided with a temperature detection device 410.

[0077] In working, the first side draft fan 110 and the second side draft fan 120 are respectively provided with temperature detection devices 410 at the front ends, when the first side draft fan 110 works, the temperature detection device 410 can detect the temperature of the first side draft fan 110 in normal working, when the temperature exceeds the set normal working temperature, the switching device will switch processing, start the second side draft fan 120 to work, at the same time, the alarm system 510 flashes and emits sound, the problem can be displayed through the touch screen control system 500, and the synchronous information will be sent to the mobile terminal or the monitoring computer in the form of information. The second side draft fan 120 works in the same way.

[0078] Continuing to refer to Figure 5 In the optional technical scheme of the embodiment, the movable pallet trolley 100 is provided with a cooling fan 400.

[0079] In working, in order to prevent the first side draft fan 110 and the second side draft fan 120 from working at high temperature and causing abnormal alarm, the cooling fan 400 is arranged in front of each side draft fan to cool the side draft fan, according to the touch screen control system 500, the start-stop temperature feedback can be set to prevent abnormal temperature alarm caused by high temperature and unable to cool. At the same time, the service life of the equipment is also improved.
