Description

Technical Field

[0001] This application relates to the field of mobile power station technology, and more specifically, to an exhaust door control device and a mobile power station. Background Technology

[0002] Military power stations, also known as "mobile power stations," are installed on various transport vehicles (such as cars, trailers, and open railway wagons) to provide electrical power to various military users under field conditions.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0055] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. These terms are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0056] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0057] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] As introduced in the background section, military power stations, also known as "mobile power stations," are installed on various transportation vehicles (such as cars, trailers, and railway wagons) to provide electrical energy to various military users under field conditions. Currently, the "reliability" of mobile power stations is receiving increasing attention. Reliability design and improvement measures for mobile power stations include: component selection; derating components; using fault-tolerant design methods (using redundancy techniques); using fault diagnosis techniques; and fully considering failure sources. During the design process, it is necessary to fully consider the characteristics of each component and equipment to achieve a reasonable and reliable design.

[0059] The power supply system of a mobile power station mainly consists of four categories: diesel engine system, generator system, control system, and power station auxiliary system. The auxiliary system primarily includes exhaust dampers, cable reels, and other auxiliary equipment. The exhaust dampers in the mobile power station mainly serve the purpose of ventilation and heat dissipation, while also facilitating maintenance.

[0060] Currently, opening or closing the exhaust door is mainly based on the motor driving the operation. However, when the exhaust door is fully open or fully closed, the motor is often still rotating. This idling can cause the motor to burn out, making the safety of the mobile power station compromised.

[0061] In view of this, the present application provides an exhaust door control device and a mobile power station. By collecting the opening and closing states of the exhaust door, the motor is automatically shut off when the exhaust door is fully open and fully closed, avoiding the motor from running dry and improving the safety of the motor, thereby improving the reliability and safety of the mobile power station.

[0062] It should be noted that the defects in the solutions in the prior art are all results obtained by the applicant after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the embodiments of this application in the following text should be considered as contributions made by the applicant to this application.

[0063] 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 key elements thereof can be combined with each other.

[0064] Please refer to the following: Figure 1 , Figure 1 This is one of the block diagrams of the exhaust door control device 1 provided in the embodiments of this application.

[0065] The exhaust door control device 1 provided in this application embodiment includes a status feedback module 10, an opening control module 20, a closing control module 30, and a motor 40. The status feedback module 10 is electrically connected to the opening control module 20 and the closing control module 30, respectively. The opening control module 20 and the closing control module 30 are electrically connected to the motor 40, respectively. The motor 40 and the status feedback module 10 are respectively connected to the exhaust door.

[0066] The status feedback module 10 is used to collect the opening and closing status information of the exhaust door, including fully open status information or fully closed status information.

[0067] The door opening control module 20 is used to run a first control state based on the fully open state information, so as to stop the motor 40 from running.

[0068] The door closing control module 30 is used to run a second control state based on the fully closed state information, so as to stop the motor 40 from running.

[0069] Understandably, a magnetic circuit can be installed on the exhaust door. When the exhaust door is opened to its maximum angle, the first magnetic component of the magnetic circuit can engage with the magnetic component of the exhaust door, causing a change in the voltage within the magnetic circuit. When the exhaust door is closed to its minimum angle, the second magnetic component of the magnetic circuit can engage with the magnetic component of the exhaust door, causing a change in the voltage within the magnetic circuit.

[0070] Thus, when motor 40 rotates, driving the exhaust damper from the closed state to the open state, until the exhaust damper is fully open (i.e., the exhaust damper opening angle is at its maximum), the status feedback module 10 can collect the fully open state information. When motor 40 rotates in the opposite direction, driving the exhaust damper from the open state to the closed state, until the exhaust damper is fully closed (i.e., the exhaust damper opening angle is at its minimum), the status feedback module 10 can collect the fully closed state information.

[0071] This application embodiment collects the opening and closing states of the exhaust door and automatically shuts down the motor 40 when the exhaust door is fully open and fully closed, avoiding the motor 40 from running dry and improving the safety of the motor 40, thereby improving the reliability and safety of the mobile power station.

[0072] In this embodiment, the motor 40 can be automatically stopped from idling by means of manual or automatic means, thereby further ensuring the reliability of the mobile power station.

[0073] The following section provides a detailed explanation of how to automatically stop the motor from idling at 40°C using an automatic control method.

[0074] As an optional implementation, automatic control can be achieved through the exhaust damper controller 50 in conjunction with the aforementioned modules. Please refer to the relevant documentation. Figure 2 , Figure 2 This is a second block diagram of an exhaust vent control device provided in an embodiment of this application. The exhaust vent control device 1 also includes an exhaust vent controller 50.

[0075] The status feedback module 10 is electrically connected to the exhaust door controller 50, and the exhaust door controller 50 is electrically connected to the door opening control module 20 and the door closing control module 30 respectively.

[0076] The exhaust door controller 50 is used to acquire the fully open status information and send a closing signal to the door opening control module 20 based on the fully open status information.

[0077] The door opening control module 20 is used to operate the first control state according to the closing signal, so as to stop the motor 40 from running.

[0078] The exhaust door controller 50 is also used to acquire fully closed status information and send a closing signal to the door closing control module 30 based on the fully closed status information.

[0079] The door closing control module 30 is used to run a second control state according to the closing signal, so as to stop the motor 40 from running.

[0080] The closing signal can be determined based on the device characteristics of the door opening control module 20 and the door closing control module 30. For example, the closing signal can be zero voltage or high voltage.

[0081] In other words, when the exhaust door is fully open, the status feedback module 10 will collect the fully closed status information and send the fully open status information to the exhaust door controller 50. The exhaust door controller 50 sends a closing signal to the door opening control module 20 based on the fully open status information. The door opening control module 20 then runs the first control state according to the closing signal, causing the motor 40 to stop running. This avoids the problem that the motor 40 will continue to rotate after the exhaust door is open, thus burning out the motor 40.

[0082] When the exhaust damper is fully closed, the status feedback module 10 collects the fully closed status information and sends it to the exhaust damper controller 50. The exhaust damper controller 50 sends a closing signal to the closing control module 30 based on the fully closed status information. The closing control module 30 then operates the second control state according to the closing signal, causing the motor 40 to stop running. This avoids the problem that the motor 40 will continue to rotate after the exhaust damper is closed, thus burning out the motor 40.

[0083] Understandably, the exhaust damper can also be automatically opened or closed based on the above-mentioned automatic control mode.

[0084] Because the engine unit of the mobile power station generates a significant amount of heat during operation, the exhaust vents can be opened to dissipate heat and ensure safe operation. When the engine unit is off, the exhaust vents can be closed to prevent dust from entering the mobile power station.

[0085] As an alternative implementation, the exhaust valve can also be automatically opened or closed based on the operating status of the engine unit and the current opening / closing status of the exhaust valve.

[0086] The exhaust damper controller 50 is communicatively connected to the engine unit controller. The exhaust damper controller 50 is used to acquire the opening and closing status information of the exhaust damper collected by the status feedback module 10 and the operating status information of the engine unit sent by the engine unit controller. The operating status information includes open status information or closed status information.

[0087] The exhaust door controller 50 generates an opening signal based on the fully closed state information and the open state information, and sends the opening signal to the door opening control module 20.

[0088] The door opening control module 20 is used to run the opening control mode based on the opening signal, so that the motor 40 rotates clockwise and opens the exhaust door.

[0089] The exhaust door controller 50 is also used to generate an open signal based on the fully open state information and the closed state information, and send the open signal to the door closing control module 30.

[0090] The door closing control module 30 is used to operate the closing control mode based on the open signal, so that the motor 40 rotates counterclockwise to close the exhaust door.

[0091] For example, when the exhaust damper controller 50 receives the fully closed status information sent by the status feedback module 10 and the open status information sent by the engine group controller, it can determine that the engine group is in the open state and the exhaust damper is in the fully closed state. At this time, the exhaust damper can be opened for heat dissipation. An open signal can be sent to the door opening control module 20, and the door opening control module 20 operates the open control mode based on the open signal, causing the motor 40 to rotate clockwise, thereby opening the exhaust damper.

[0092] Understandably, when the exhaust door is fully open, the exhaust door controller 50 can also send a closing signal to the door opening control module 20, so that the door opening control module 20 stops running the open control mode (i.e., the door opening control mode runs in the first control state), so that the motor 40 stops running, avoiding the problem that the motor 40 will still run idle after the exhaust door is fully open, which would cause the motor 40 to burn out.

[0093] For example, when the exhaust damper controller 50 receives the fully open status information sent by the status feedback module 10 and the closed status information sent by the engine unit controller, it can determine that the engine unit is in the closed state and the exhaust damper is in the fully open state. At this time, the exhaust damper can be closed to prevent dust from entering the mobile power station. The exhaust damper controller 50 can send an open signal to the door closing control module 30. The door closing control module 30 operates the door closing control mode based on the open signal, causing the motor 40 to rotate counterclockwise, thereby closing the exhaust damper.

[0094] Understandably, after the exhaust door is completely closed, the exhaust door controller 50 can also send a closing signal to the door closing control module 30, so that the door closing control module 30 stops running the closing control mode (i.e., the door closing control mode runs the second control state), so that the motor 40 stops running, avoiding the problem that the motor 40 will still run idle after the exhaust door is completely closed, which would cause the motor 40 to burn out.

[0095] Based on the exhaust door controller 50 and the connection relationship of each component provided in the embodiments of this application, an automatic control mode can be realized, which facilitates the operation of the mobile power station.

[0096] The following section provides a detailed explanation of how to achieve automatic motor stoppage at 40°C using manual control.

[0097] As an optional implementation, manual control can be achieved through the control switch 60 in conjunction with the aforementioned modules. Please refer to the relevant documentation. Figure 3 , Figure 3 This is a third block diagram of an exhaust vent control device provided in an embodiment of this application. The exhaust vent control device 1 also includes a control switch 60. The control switch 60 includes a first position and a second position.

[0098] The control switch 60 is electrically connected to the door opening control module 20 and the door closing control module 30, respectively.

[0099] When the control switch 60 is in the first position, the door opening control module 20 is used to run the first control state based on the fully open state information, so as to stop the motor 40 from running.

[0100] When the control switch 60 is in the second position, the door closing control module 30 uses the fully closed state information to run the second control state to stop the motor 40 from running.

[0101] In other words, staff can manually turn the control switch 60 to different positions as needed, so that the closing control module 30 runs in the second control state or the opening control module 20 runs in the first control state, thereby stopping the motor 40 from running and avoiding the problem of the motor 40 running idle and burning out after the exhaust door is opened to the maximum or completely closed.

[0102] It is understood that, based on the above manual control method, this embodiment of the application can also control the opening or closing of the exhaust door according to the position of the control switch 60.

[0103] In an optional implementation, when the control switch 60 is in the first position, the door opening control module 20 is also used to operate the open control mode, so that the motor 40 rotates clockwise to open the exhaust door. It is understood that when the exhaust door is fully open, the status feedback module 10 can collect the fully open status information. At this time, the door opening control module 20 stops operating the open control mode (i.e., the door opening control module 20 operates in the first control state), so that the motor 40 stops running.

[0104] When the control switch 60 is in the second position, the door closing control module 30 operates in the closing control mode, causing the motor 40 to rotate counterclockwise and close the exhaust door. It is understood that once the exhaust door is fully closed, the status feedback module 10 can collect the fully closed status information. At this time, the door closing control module 30 stops operating in the closing control mode (i.e., the door closing control module 30 operates in the second control state), causing the motor 40 to stop running.

[0105] The following provides a possible implementation method, and details the specific devices and implementation principles included in each of the above modules in terms of their functions.

[0106] Please refer to the following: Figure 4 In an optional embodiment, the status feedback module 10 includes a feedback unit, which includes a first feedback relay and a second feedback relay. The first feedback relay includes a first feedback coil KA21, a first normally closed contact KA21_1, and a first normally open contact KA21_2. The second feedback relay includes a second feedback coil KA22, a second normally closed contact KA22_1, and a second normally open contact KA22_2.

[0107] One end of the first feedback coil KA21 is connected to the opening limit switch of the exhaust door, and the other end of the first feedback coil KA21 is connected in parallel with the door opening control module 20 and the door closing control module 30.

[0108] One end of the first normally closed contact KA21_1 is grounded, and the other end of the first normally closed contact KA21_1 is electrically connected to the door opening control module 20.

[0109] One end of the first normally open contact KA21_2 is connected in parallel with the first feedback coil KA21, and the other end of the first normally open contact KA21_2 is electrically connected to the exhaust damper controller 50.

[0110] When the voltage of the limit switch is low, the first feedback coil KA21 is energized, and the first normally open contact KA21_2 closes to collect and send the fully open status information to the exhaust damper controller 50.

[0111] The opening limit switch can be connected to the first magnetic element in the magnetic circuit on the exhaust door. When the exhaust door is opened to its maximum angle, the second magnetic element in the magnetic circuit can engage with the magnetic components of the exhaust door, causing a change in the voltage in the magnetic circuit, i.e., the voltage of the opening limit switch changes from high to low. At this time, the feedback unit can collect the fully open state information based on the voltage change.

[0112] Next, when the voltage of the limit switch is low, the first feedback coil KA21 is energized, the first normally open contact KA21_2 closes, and the feedback unit forms a path with the exhaust door controller 50 to send the fully open status information to the exhaust door controller 50.

[0113] Furthermore, one end of the second feedback coil KA22 is connected to the closing limit switch included in the exhaust door, and the other end of the second feedback coil KA22 is connected in parallel with the first feedback coil KA21.

[0114] One end of the second normally closed contact KA22_1 is grounded, and the other end of the second normally closed contact KA22_1 is electrically connected to the door closing control module 30.

[0115] One end of the second normally open contact KA22_2 is connected in parallel with the second feedback coil, and the other end of the second normally open contact KA22_2 is electrically connected to the exhaust damper controller 50.

[0116] When the voltage of the limit switch is low, the second feedback coil KA22 is energized, and the second normally open contact KA22_2 closes to collect and send the fully closed status information to the exhaust door controller 50.

[0117] The aforementioned closing limit switch can be connected to the second magnetic element in the magnetic attraction circuit on the exhaust door. When the exhaust door is closed to its minimum angle, the second magnetic element in the magnetic attraction circuit can engage with the magnetic components of the exhaust door, causing a change in the voltage in the magnetic attraction circuit, i.e., the voltage of the closing limit switch changes from high to low. At this time, the feedback unit can collect the fully closed state information based on the voltage change.

[0118] Next, since the voltage of the limit switch is low, the second feedback coil KA22 is energized. Therefore, the second normally open contact KA22_2 closes, and the feedback unit forms a path with the exhaust door controller 50 to send a fully closed status information to the exhaust door controller 50.

[0119] Furthermore, in an optional embodiment, the status feedback module 10 further includes a status display unit, one end of which is connected in parallel with the door opening control module 20 and the door closing control module 30, and the other end of which is electrically connected to the opening limit and the closing limit, respectively.

[0120] The status display unit is used to display first information when the opening limit voltage is low, indicating that the exhaust damper is in the fully open state.

[0121] The status display unit is also used to display a second message when the limit voltage is high, indicating that the exhaust damper is in a fully closed state.

[0122] Optionally, the status feedback module 10 can be an LED light group or an LCD display.

[0123] When the status feedback module 10 is an LED light group (such as...) Figure 4 In the case of HL08), the LED light assembly may include two LED tubes that emit different colors, for example, a first LED tube and a second LED tube, where the first LED tube emits green light and the second LED tube emits red light. The two LED tubes are connected in parallel, with one end of each LED tube connected in parallel to both the door opening control module 20 and the door closing control module 30. The other end of the first LED tube is connected to the open limit switch, and the other end of the second LED tube is connected to the close limit switch.

[0124] When the exhaust damper is fully open, the limit voltage is low, at which point the first LED tube is connected and emits green light.

[0125] When the exhaust damper is fully closed, the limit voltage is low, at which point the second LED tube is connected and emits red light.

[0126] In this way, staff can determine the status of the exhaust door based on the color displayed by the status display unit, i.e., the LED light group.

[0127] Similarly, when the status feedback module 10 is an LCD display, the first information may include: "The exhaust door is fully open," and the second information may include: "The exhaust door is fully closed." Thus, staff can determine the status of the exhaust door based on the information displayed on the status display unit, i.e., the LCD display.

[0128] Please continue reading. Figure 4 In an optional implementation, the door opening control module 20 includes a door opening relay and a first diode. The door opening relay includes a third feedback coil KA08 and a third normally open contact group (KA08_1 and KA08_2). The first diode includes a first positive terminal and a first negative terminal.

[0129] The first positive terminal is electrically connected to the exhaust damper controller 50, the first negative terminal is electrically connected to one end of the third feedback coil KA08, the other end of the third feedback coil KA08 is electrically connected to the first normally closed contact KA21_1, and the third normally open contact group (KA08_1 and KA08_2) is electrically connected to the positive and negative power supply terminals of the motor 40, respectively.

[0130] Based on the above circuit, the principle behind automatically opening the exhaust damper and automatically stopping the motor 40 in automatic control mode is as follows:

[0131] like Figure 4 As shown, when the exhaust damper is fully closed, the limit switch is at a low voltage. At this time, the second feedback coil KA22 is energized, the second normally closed contact KA22_1 is opened, and the second normally open contact KA22_2 is closed, so that the status feedback module 10 is connected to the exhaust damper controller 50, and the exhaust damper controller 50 obtains the fully closed status information.

[0132] If the exhaust damper needs to be opened, the exhaust damper controller 50 sends an open signal to the opening relay via the 487A line. That is, the first diode is turned on, the third feedback coil KA08 included in the opening relay is energized, and the third normally open contact group (KA08_1 and KA08_2) is closed, so that the positive and negative terminals of the power supply of the motor 40 are connected, thereby causing the motor 40 to rotate forward (clockwise) and drive the exhaust damper to open.

[0133] When the exhaust damper is fully open, the opening limit switch is at a low voltage. At this time, the first feedback coil KA21 is energized, the first normally closed contact KA21_1 opens, and the first normally open contact KA21_2 closes, connecting the status feedback module 10 with the exhaust damper controller 50. The exhaust damper controller 50 then obtains the fully open status information. Simultaneously, the exhaust damper controller 50 sends a closing signal to the opening control module 20, the first diode is cut off, and the third feedback coil KA08, included in the opening relay, is de-energized. Furthermore, the first normally closed contact KA21_1 opens, and the third feedback coil KA08 is also de-energized, causing the third normally open contact group (KA08_1 and KA08_2) to open. This disconnects the positive and negative terminals of the power supply to the motor 40, stopping the motor 40 from rotating and preventing it from burning out due to idling.

[0134] Please continue reading. Figure 4 , Figure 4 SA08_1, shown in the diagram, represents the first position of control switch 60, and SA08_2 represents the second position of control switch 60. Based on the above circuit, the principle of opening the exhaust damper and automatically stopping the motor 40 in manual control mode is as follows:

[0135] When the control switch 60 is in the first position, SA08_1 is closed, the third feedback coil KA08 of the door opening relay is energized, and the third normally open contact group (KA08_1 and KA08_1) is closed, so that the positive and negative terminals of the power supply of the motor 40 are connected, thereby causing the motor 40 to rotate forward (clockwise) and drive the exhaust door to open.

[0136] When the exhaust damper is fully opened, the limit switch is at a low voltage. At this time, the first feedback coil KA21 is energized, the first normally closed contact KA21_1 is opened, causing the third feedback coil KA08 to be de-energized, thereby causing the third normally open contact group (KA08_1 and KA08_2) to open. The positive and negative terminals of the power supply of motor 40 are disconnected, thereby stopping motor 40 from rotating and preventing motor 40 from burning out due to idling.

[0137] Please continue reading. Figure 4 In an optional implementation, the door closing control module 30 includes a door closing relay and a second diode. The door closing relay includes a fourth feedback coil KA09 and a fourth normally open contact group (KA09_1 and KA09_2). The second diode includes a second positive terminal and a second negative terminal.

[0138] The second positive terminal is electrically connected to the exhaust damper controller 50, the second negative terminal is electrically connected to one end of the fourth feedback coil KA09, the other end of the fourth feedback coil KA09 is electrically connected to the second normally closed contact (KA22_1), and the fourth normally open contact group (KA09_1 and KA09_2) is electrically connected to the negative and positive power supply terminals of the motor 40, respectively.

[0139] Based on the above circuit, the principle behind automatically closing the exhaust damper and stopping the motor 40 in automatic control mode is as follows:

[0140] When the exhaust damper is fully open, the opening limit switch is at a low voltage. At this time, the first feedback coil KA21 is energized, the first normally closed contact KA21_1 is opened, and the first normally open contact KA21_2 is closed, so that the status feedback module 10 is connected to the exhaust damper controller 50, and the exhaust damper controller 50 obtains the fully open status information.

[0141] If the exhaust damper needs to be closed, the exhaust damper controller 50 sends an open signal to the closing relay via the 488A line. That is, the second diode is turned on, the fourth feedback coil KA09 of the closing relay is energized, and the fourth normally open contact group (KA09_1 and KA09_2) is closed, so that the positive and negative terminals of the power supply of the motor 40 are connected, thereby causing the motor 40 to reverse (rotate counterclockwise) and drive the exhaust damper to close.

[0142] When the exhaust damper is fully closed, the limit switch is at a low voltage. At this time, the second feedback coil KA22 is energized, the second normally closed contact KA22_1 opens, and the second normally open contact KA22_2 closes, connecting the status feedback module 10 to the exhaust damper controller 50. The exhaust damper controller 50 then obtains the fully closed status information. Simultaneously, the exhaust damper controller 50 sends a closing signal to the closing control module 30, the second diode is cut off, and the fourth feedback coil KA09 included in the closing relay is de-energized. Furthermore, the second normally closed contact KA22_1 opens, similarly de-energizing the fourth feedback coil KA09, thereby disconnecting the fourth normally open contact group (KA09_1 and KA09_2). This disconnects the positive and negative terminals of the power supply, causing the motor 40 to stop rotating and preventing it from burning out due to idling.

[0143] Please continue reading. Figure 4 , Figure 4 SA08_1 is shown as the first position of control switch 60, and SA08_2 is shown as the second position of control switch 60. Based on the above circuit, the principle of closing the exhaust damper and automatically stopping the motor 40 in manual control mode is as follows:

[0144] When the control switch 60 is in the second position, SA08_2 is closed, the fourth feedback coil KA09 of the door closing relay is energized, and the fourth normally open contact group (KA09_1 and KA09_2) is closed, so that the positive and negative terminals of the power supply of the motor 40 are connected, thereby causing the motor 40 to reverse (rotate counterclockwise) and drive the exhaust door to close.

[0145] When the exhaust damper is fully closed, the limit switch is at a low voltage. At this time, the second feedback coil KA22 is energized, the second normally closed contact KA22_1 is opened, causing the fourth feedback coil KA09 to be de-energized. As a result, the fourth normally open contact group (KA09_1 and KA09_2) is opened, and the positive and negative terminals of the power supply are disconnected, thereby stopping the motor 40 from rotating and preventing the motor 40 from burning out due to idling.

[0147] The exhaust door control device is used to control the opening or closing of the exhaust door.

[0148] Since the principle of the mobile power station in this application embodiment for solving related problems is similar to that of the exhaust door control device 1 described above in this application embodiment, the implementation principle of the mobile power station can be referred to the implementation principle of the exhaust door control device 1, and the repeated parts will not be described again.
