The hot chamber 6 includes an air intake chamber 61 and an air extraction chamber 62 which are isolated from each other. An air fan 63 is arranged in the air extraction chamber 62 and the chamber is connected to the regulating chamber 5 through a ventilation slot 14. The air intake chamber 61 is provided with an air intake side wall 8 connected to the outside, and the air intake chamber 61 is also connected to the regulating chamber 5. A filter screen plate 81, a pressure block 82 for limiting the filter screen plate 81, and a limiting rod 83 which penetrates the frame of the filter screen plate 81 are arranged on the air intake side wall 8. The pressure block 82 is threadedly matched with a screw member 86 with a driving motor 85. The pressure block 82 is driven by the screw member 86 to move axially along the screw member 86 to abut against the filter screen plate 81. The limiting rod 83 is provided with a telescopic electric cylinder 84 which is telescopic relative to the filter screen plate 81. After the cylinder contracts, the filter screen plate 81 which is close to the air intake side wall 8 falls due to gravity.
[0018] As a further configuration of the above scheme, the simple control cavity 7 is connected to the control device cavity 4 via a cable, and a display screen 71 and a control operation switch 72 are arranged in the simple control cavity 7 to adjust parameters of the power components in the control device cavity 4.
[0019] As a further arrangement of the above scheme, the driving motor 85 and the screw member 86 are also provided with a linkage rotating rod 88, and the linkage rotating rod 88 and the screw member 86 are transmitted by a bevel gear 89, and a plurality of the screw members 86 rotate synchronously, and the threaded drive pressure block 82 moves synchronously, and the pressure block 82 is circumferentially fixed relative to the air inlet chamber 61.
[0020] As a further configuration of the above scheme, the driving motor 85 and the telescopic electric cylinder 84 are electrically connected and provided with a controller, and the controller is also provided with a plurality of air pressure sensors, and the air pressure sensors are arranged in the control device cavity 4, the regulating cavity 5, the air inlet chamber 61 and the air exhaust cavity 62, and are used to provide the controller with the air pressure value in the cavity, triggering the start and stop of the driving motor 85 and the telescopic electric cylinder 84.
[0021] As a further configuration of the above scheme, the sealing structure 3 includes an annular panel 21 arranged on the opening and closing door 2 of the control device chamber 4 and the regulating chamber 5, and a groove 22 with a recessed airbag 111 is arranged on the front frame 11 of the opening and closing door 2 of the control device chamber 4 and the regulating chamber 5. An electromagnetic valve 68 with a micro air pump is also arranged in the air inlet chamber 61. The electromagnetic valve 68 is connected to the recessed airbag 111, and the electromagnetic valve 68 is used for filling and extracting gas in the recessed airbag 111.
[0022] The present embodiment is a comprehensive intelligent power-saving protection device, comprising a power-saving cabinet 1, wherein the power-saving cabinet 1 is composed of a frame 11 and a sealing plate 12 to form a plurality of cabinet cavities, and an opening and closing door 2 is arranged on the front to close the cabinet cavities. The opening and closing door 2 on the front is also an operation port for equipment shutdown and maintenance. It is worth noting that Figure 1-2 As shown, the protective device of this embodiment has a box cavity composed of four main chambers, namely a control device cavity 4, an adjusting cavity 5, a ventilation and heat dissipation cavity 6 and a simple control cavity 7, and the ventilation and heat dissipation cavity 6 is divided into an air intake chamber 61 and an air extraction chamber 62. The whole ventilation airflow circulation system is composed of external air first entering the air intake chamber 61 from the air intake port on the air intake side wall 8 through the filter screen plate 81, and then entering through the ventilation slots 14 on the air intake chamber 61 and the partition 13 of the adjusting cavity 5, and then going out from the ventilation slots 14 on the partition 13 of the air extraction chamber 62 and the adjusting cavity 5, and then being discharged from the bottom outlet of the air extraction chamber 62. The flow power comes from the air fan 63 arranged in the air extraction cavity 62. When the air fan 63 is started, the air in the adjusting cavity 5 is extracted to form a negative pressure environment, thereby starting the above-mentioned air circulation.
[0023] It is worth noting that after the air fan 63 in the present embodiment is started, its suction capacity is sufficient to form a negative pressure state in the regulating chamber 5 without an air inlet opening. Therefore, combined with the filter screen plate 81 and the air pressure sensor provided in the present embodiment, when the filter material is blocked on the filter screen plate 81, resulting in difficulty in air intake and causing the internal air pressure to be lower than the external air pressure, the controller obtains the air pressure value to trigger the control command: ① Start the telescopic electric cylinder 84 to retract the limit rod 83 (at least two limit rods 83 and telescopic electric cylinders 84 are provided, and they are synchronously retracted based on the controller), so that the distance between the front end of the limit rod 83 and the air inlet side wall 8 becomes larger, until the size is larger than 1 layer of the filter screen plate 81 and smaller than 1.5 layers of the filter screen plate 81. At this time, the limit rod 83 The outermost filter screen plate 81 no longer has a limiting effect, and the drive motor 85 is then started to reverse, driving the screw member 86 to rotate (and based on the cooperation of several linkage rotating rods 88 with bevel gears 89 and the bevel gears 89 set on the screw member 86, all the screw members 86 can be synchronously rotated forward and reversed), driving the pressure block 82 to move, and releasing the pressure on all the filter screen plates 81. After losing the horizontal clamping force of the pressure block 82, the outermost filter screen plate 81 naturally falls without external support, and then the telescopic electric cylinder 84 is started again to push the electric cylinder piston rod, and the limiting rod 83 extends toward the air intake side wall 8 to reset. After the reset is completed, the drive motor 85 rotates forward until the pressure block 82 completes the clamping of the remaining filter screen plates 81 again.
[0024] As for the structure as described above, it should be noted that the side of the outermost filter screen plate 81 is also provided with a transmitting end and a receiving end of an infrared sensor. The infrared sensor is arranged opposite to the side of the second last filter screen plate 81 and is connected to the controller. When the second last filter screen plate 81 falls off, a prompt will be issued to remind the user that the filter screen plate 81 needs to be replaced. When replacing, the above-mentioned action can be performed by actively operating the controller, and the telescopic electric cylinder 84 is retracted, and then the drive motor 85 is controlled to reverse to leave enough space, and then the new filter screen plates 81 are stacked layer by layer. In this way, when in use, once the outermost layer is blocked, it can be automatically and timely replaced by the device, thereby extending the time period for replacing the screen, avoiding frequent replacement of the screen, and reducing the workload of the staff.
[0025] Furthermore, in the device of the present embodiment, after the opening and closing door 2 is closed, the annular panel 21 on the opening and closing door 2 will be inserted into the embedded groove 22 on the front frame 11 of the control device cavity 4 and the regulating cavity 5 relative to the opening and closing door 2. Subsequently, the electromagnetic valve 68 opens the air circuit suction pump to start pumping air into the recessed airbag 111 to expand it. The expanded airbag will tightly wrap the annular panel 21, thereby completing the internal and external sealing of the control device cavity 4 and the regulating cavity 5. When the door is opened, the electromagnetic valve 68 will also open, and the suction pump will extract the air in the recessed airbag 111. This structure can make the door that is not often opened open. The control device chamber 4 and the adjustment chamber 5 are sealed to reduce the air entering and exiting from the opening and closing door 2. Therefore, in the ventilation and heat dissipation chamber 6 and the simple control chamber 7, it is only necessary to fix the sealing pad and simply seal it without designing a complicated high-sealing structure. The switch of the electromagnetic valve 68 and the vacuum pump can also be linked with the electronic door lock on the front door of the opening and closing door 2. When someone unlocks and closes the door, the vacuum pump and the electromagnetic valve 68 are triggered. Referring to the lighting in the refrigerator in the prior art, the light is turned on when the door is opened and the light is turned off after the door is closed, and combined with a timer, the countdown can be started and closed.
[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
