[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Current grain silo sealing doors typically include an electric actuator for automatic opening and closing. However, this actuator is usually externally mounted behind the door or door frame, on the inside side of the grain silo, exposed to the internal air. When phosphine or similar chemicals are used to fumigate the grain to prevent pests and diseases, the air inside the silo is filled with a certain concentration of phosphine. Under these conditions, the metal parts of the electric actuator will corrode. Once the metal parts are corroded and rusted, the failure rate of the electric actuator increases significantly, leading to insufficient operational reliability of the grain silo sealing door. To address these problems, the main objective of this application is to propose an electric sealing door device that reduces the corrosion of the electric actuator during the fumigation process inside the grain silo, lowers the failure rate of the electric actuator, and thus improves the operational reliability of the grain silo sealing door.

[0040] Figure 1 This is a schematic diagram of a sealing door device provided in one embodiment of this application. The sealing door can be installed, for example, at the inlet / outlet or air vent of a grain silo, but is not limited thereto. Figure 1 As shown, the sealing door device includes: a door frame 1, a door leaf 2, a hinge 3, an electric sealing device 4, and an electrical control device 5.

The electric sealing device 4 includes a sealing box and an electric actuator installed inside the sealing box. The electric actuator is electrically connected to the electrical control device 5 and is driven by the electric actuator to the door leaf 2.

[0042] For example, the materials of the aforementioned door frame 1, door leaf 2, hinge 3, and sealing box can be corrosion-resistant materials, but the specific material is not limited here. It is also understood that the size and model of the aforementioned door frame 1 and door leaf 2 can be selected or adjusted according to actual needs. The aforementioned hinge 3 can be, for example, a detachable hinge 3, but is not limited thereto. Furthermore, the number of hinges 3 is not limited to the two shown in the figure; it can also be three or other quantities, depending on actual needs, and is not limited here.

It is understood that the specific shape and size of the sealed box, the size, shape, and actual number of the through holes, the specific electrical connection method between the electric actuator and the electrical control device 5, and the specific transmission connection method between the electric actuator and the door leaf 2 can all be selected and determined according to the actual situation, with the aim of realizing the necessary functions, and no specific restrictions are made here.

[0044] After the door leaf 2 is closed, it can fit tightly against the door frame 1 to achieve a seal. Furthermore, a sealing strip can be provided at the joint between the door leaf 2 and the door frame 1 to further enhance the seal. The sealing strip can be attached to the door frame 1. Of course, the above is only one possible example. The actual sealing method between the door leaf 2 and the door frame 1, as well as the type, material, quantity, location, and installation method of the sealing strip, can be selected and adjusted according to the specific circumstances, and no restrictions are imposed here.

[0045] The sealing door device provided in this application includes: a door frame 1, a door leaf 2, a hinge 3, an electric sealing device 4, and an electrical control device 5. The door frame 1 is connected to the door leaf 2 via the hinge 3. The electric sealing device 4 is disposed within the door frame 1 and includes: a sealing box and an electric actuator disposed within the sealing box. The electric actuator is electrically connected to the electrical control device 5 and is drive-connected to the door leaf 2. This sealing door device, by setting a sealing box within the door frame 1 and housing the electric actuator within the sealing box, with only a through-hole for the electric actuator to drive the door leaf 2, ensures that when the sealing door is closed, the electric actuator is not exposed to the air environment inside the grain silo. This protects the metal parts of the electric actuator from corrosion by the fumigation gases inside the grain silo, thereby reducing the failure rate of the electric actuator and improving the operational reliability of the grain silo sealing door.

[0046] Please continue to refer to Figure 1 Furthermore, based on the above embodiments, the electric actuator includes: a stepper motor, a gear transmission mechanism, and a chain transmission mechanism 6, wherein the stepper motor is electrically connected to the electrical control device 5, the stepper motor is connected to the gear transmission mechanism, the gear transmission mechanism is connected to the chain transmission mechanism 6, and the chain transmission mechanism 6 is connected to the door leaf 2.

The number, type, size, etc. of the chain in the chain transmission mechanism 6 mentioned above can also be selected and determined according to the actual situation.

[0048] The stepper motor is electrically connected to the aforementioned electrical control device 5. For example, the aforementioned electrical control device 5 can provide forward or reverse current to the aforementioned stepper motor to realize the forward or reverse rotation of the stepper motor, thereby driving the forward or reverse rotation of the aforementioned gear transmission mechanism and the extension or retraction of the chain transmission mechanism 6, ultimately realizing the opening and closing of the aforementioned door leaf 2. The aforementioned chain transmission mechanism 6 is connected to the aforementioned door leaf 2. For example, the aforementioned chain transmission mechanism 6 can be connected to the top of the door leaf 2 through connectors including but not limited to fasteners, etc. Of course, it is not limited to being connected to the top of the door leaf 2.

[0050] The aforementioned open limit switch 7 and the aforementioned closed limit switch 8 are respectively electrically connected to the aforementioned electrical control device 5.

[0051] For example, the aforementioned open-position limit switch 7 and closed-position limit switch 8 may be sensors, including but not limited to those that detect whether the door 2 is closed or open to a preset position through inductance, magnetism, light, pressure, etc. The aforementioned electrical control device 5 may receive the detection results of the aforementioned open-position limit switch 7 and closed-position limit switch 8 through the aforementioned electrical connection, so as to stop supplying power to the aforementioned electric actuator when the aforementioned door 2 is closed / opened to the preset position, or continue to supply power to the aforementioned electric actuator when the aforementioned door 2 is not closed / not open to the preset position. If the aforementioned door 2 is still not closed / not open to the preset position after the aforementioned electric actuator has been continuously supplied with power for a preset time, the aforementioned electrical control device 5 may also provide a prompt through a preset method. However, the specific methods included in the preset method can be selected and determined according to actual needs, and no specific restrictions are made here.

Figure 1 and Figure 2 Based on the above embodiments, the electrical control device 5 includes: a control box 51, a power module 52, a control module 53 and a DC relay 54 disposed in the control box 51.

[0053] The first end of the DC relay 54 is connected to the output end 521 of the power module, the second end of the DC relay 54 is electrically connected to the electric actuator, and the control end of the DC relay 54 is also electrically connected to the control module 53.

[0054] The aforementioned control module 53 is also electrically connected to the aforementioned open limit switch 7 and the aforementioned closed limit switch 8.

[0055] For example, the control box 51 can be a PC waterproof box including a transparent cover, a middle plate, a bottom plate, etc. The control box 51 can be provided with at least one through hole, which can be used as a cable inlet / outlet hole for cable entry and exit. The power module 52, control module 53 and DC relay 54 disposed in the control box 51 can be disposed on the bottom plate of the control box 51, but are not limited thereto.

[0056] The power module 52 mentioned above can be, for example, an AC 220V to DC 24V power supply. Of course, the power supply parameters of the power module 52 can be adjusted adaptively according to the model and parameters of the DC relay 54 and other components, and are not limited to an AC 220V to DC 24V power supply. Taking the power module 52 as an example of an AC 220V to DC 24V power supply, the first end of the DC relay 54 is connected to the output end 521 of the power module. For example, the output end 521 of the power module can supply power to the DC relay 54 in the form of DC 24V.

[0057] The second terminal of the aforementioned DC relay 54 is electrically connected to the aforementioned electric actuator, and the control terminal of the aforementioned DC relay 54 is also electrically connected to the aforementioned control module 53. For example, it can be said that the aforementioned DC relay 54, under the control of the control terminal, supplies power to the aforementioned electric actuator with DC 24V so that the stepper motor in the electric actuator rotates.

[0058] The aforementioned electrical control device 5 can, for example, receive the detection results of the open-position limit switch 7 and the closed-position limit switch 8 through the aforementioned electrical connection. For example, the aforementioned control module 53 can receive the detection results of the open-position limit switch 7 and the closed-position limit switch 8 through the aforementioned electrical connection.

The drive contact 5422 of the direction relay serves as the second terminal of the DC relay 54 and is used to electrically connect to the electric actuator.

[0060] The control input terminal 5413 of the aforementioned action relay and the control input terminal 5423 of the aforementioned direction relay are the control terminals of the aforementioned DC relay 54.

[0061] Figure 4 A schematic diagram of the structure of the electrical control device 5 provided in another embodiment of this application is shown. Optionally, please refer to... Figure 4 ,exist Figure 3 Based on the embodiments, the electrical control device 5 may further include a signal amplification module 55 disposed within the control box 51.

[0062] The output terminal 521 of the power supply module is also connected to the power supply terminal 551 of the signal amplification module, and the two input terminals 552 of the signal amplification module are respectively connected to the first output terminal 531 and the second output terminal of the control module.

[0063] The two output terminals 553 of the above signal amplification module are electrically connected to the control input terminal 5413 of the above action relay and the control input terminal 5423 of the above direction relay, respectively.

[0064] For example, the signal amplification module 55 may be a dual-channel 3.3V signal amplifier, but is not limited thereto. The function of the signal amplifier may be to compensate and amplify the signals output from the first output terminal 531 and the second output terminal of the control module, so that the signals output from the first output terminal 531 and the second output terminal of the control module can be transmitted more stably, with better quality and over a longer distance to the control input terminal 5413 of the action relay and the control input terminal 5423 of the direction relay.

[0065] In addition, in the aforementioned Figure 2 Based on the embodiments, the above-mentioned electrical control device 5 may further include: a voice module disposed in the control box 51, the voice module being connected to the control module 53.

[0066] For example, the voice module can cause the control module 53 to generate a control signal based on the collected voice commands, and then start or stop the stepper motor through the DC relay 54.

[0067] Corresponding to the voice module, the electrical control device 5 may also include a three-position switch, which may be set in the control box 51. By tossing the three-position switch to different positions, the electrical control device 5 can be controlled to be in voice control mode, manual control mode and off mode respectively. However, the specific setting location, connection method, switch model, etc. can be freely selected and determined according to actual needs, and no specific restrictions are imposed here.

[0069] For example, the first indicator light and the second indicator light can be used to indicate the energization status of the power contact 5411 of the action relay and the drive contact 5422 of the direction relay, respectively, so as to facilitate faster troubleshooting of the electrical control device 5 when the sealing door device malfunctions.

[0070] Figure 5 This is a schematic diagram of the structure of an electrical control device 5 provided in another embodiment of this application. Optionally, as shown... Figure 5 As shown above, in the aforementioned Figure 2 Based on the embodiment, the above-mentioned electrical control device 5 further includes: an AC relay 56, the input contact 561 of the AC relay being connected to the air valve output terminal of the air conditioner, and the detection output contact 562 of the AC relay being connected to the input terminal 533 of the control module.

[0071] For example, Figure 5 For example, the embodiment can be used to illustrate a scenario where the sealing door device is installed at the air inlet and outlet of a grain silo, and the sealing door device, fan, air conditioner, etc. are linked for control.

[0072] Continuing with the example above, when the three-position switch is in voice control mode, the control module 53 can periodically detect the level of the input terminal 533 of the control module to determine the operating status of the fan, air conditioner, etc. The periodic detection of the level of the input terminal 533 of the control module by the control module 53 can mean, for example, once every 1 second, once every 2 seconds, etc., but is not limited to this.

[0073] When the control module 53 detects for at least two consecutive cycles that the input state of the control module 533 is the same as the input state of the control module when the fan or air conditioner is turned on, for example, when the control module 53 detects for at least two consecutive cycles that the input state of the control module 533 is low, then the first output terminal 531 and the second output terminal 532 of the control module can be set to the level state corresponding to opening the door 2. For example, the first output terminal 531 can be high and the second output terminal 532 can be low, but this is not a limitation. When the first output terminal 531 and the second output terminal 532 of the control module are set to the level state corresponding to opening the door 2 and maintained for a certain preset time, such as 28 seconds, to ensure that the door 2 has been opened to the preset position, the first output terminal 531 and the second output terminal 532 of the control module can be set to stop the level state corresponding to opening the door 2. For example, both the first output terminal 531 and the second output terminal 532 of the control module can be low, but this is not a limitation.

[0074] When the control module 53 detects for at least two consecutive cycles that the input state of the control module 533 is the same as the input state of the control module when the fan or air conditioner is off, for example, when the control module 53 detects for at least two consecutive cycles that the input state of the control module 533 is high, then the first output terminal 531 and the second output terminal 532 of the control module can be set to the level state corresponding to closing the door 2. For example, the first output terminal 531 can be low and the second output terminal 532 can be high, but this is not a limitation. When the first output terminal 531 and the second output terminal 532 of the control module are set to the level state corresponding to closing the door 2, and after maintaining this level state for a certain preset time, such as 31 seconds, to ensure that the door 2 is closed, the first output terminal 531 and the second output terminal 532 of the control module can be set to stop the level state corresponding to the door 2. For example, both the first output terminal 531 and the second output terminal 532 of the control module can be low, but this is not a limitation.

[0075] It is understood that the above examples are only one possible scenario for the linkage control of sealing door devices with fans, air conditioners, etc. The level state, period frequency, preset duration, etc. can be adjusted and determined according to the actual situation. Furthermore, the specific implementation method for the linkage control of sealing door devices with fans, air conditioners, etc. can be completely different from the above examples and is not limited to the above content.
