Description

Technical Field

[0001] This disclosure relates to the technical field of remote emergency door closing independent systems for emergency doors at the intake of large hydropower plants, and particularly to an independent emergency door system and an emergency handling method and apparatus. Background Technology

[0002] According to NB / T 35076-2016 "Design Specification for Secondary Wiring of Hydropower Plants", the central control room should be equipped with emergency operation equipment and circuits independent of the monitoring system, which can manually and urgently close the emergency gate and the unit inlet valve; the local control panel should be equipped with emergency operation equipment and circuits independent of the monitoring system, which can manually and urgently close the emergency gate and the unit inlet valve.

[0003] Whether the inlet emergency valve can operate normally directly affects whether the turbine generator unit can generate electricity normally. When the turbine generator is generating electricity normally, the inlet emergency valve is in the fully open position. If it is accidentally operated during operation and causes the inlet emergency valve to close in an emergency, it will lead to a mechanical failure and shutdown of the unit. If the generator outlet circuit breaker fails to open normally, it will lead to the unit operating in phase shift, which seriously violates the grid dispatch discipline and causes huge economic losses to the power plant.

The first signal transmitting device is used to convert the control cabinet door closing switch signal into a door closing optical signal, and the second signal transmitting device is used to convert the control cabinet unlocking switch signal into an unlocking optical signal and send it to the gate.

[0010] According to one embodiment of this disclosure, the gate is provided with a signal receiving device, which is used to receive the gate closing light signal and / or the unlocking light signal, and convert them into gate closing switch signal and / or unlocking switch signal, respectively.

[0023] Figure 5 This is a schematic diagram of an electronic device according to one embodiment of the present disclosure. Detailed Implementation

[0024] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0025] Figure 1 This is a schematic diagram of the structure of an independent emergency door system proposed in this disclosure, as shown below. Figure 1 As shown, the system includes an operation cabinet 110 and at least one gate 120, wherein the gate 120 and the operation cabinet 110 are connected.

[0026] It should be noted that the control cabinet 110 can be located in an operating room far from the gate 120. The distance between the operating room and the gate 120 can be set according to the actual situation, and no limitation is made here. In terms of distance, it can be 1KM, 100M, etc.

[0027] It should be noted that gate 120 is a gate-closing device installed at river mouths, dam mouths, etc., to serve as an emergency closing mechanism in emergency situations. There can be multiple gates 120, depending on the actual situation; for example, there can be seven gates 120.

[0028] In the embodiments disclosed herein, such as Figure 1 As shown, the control cabinet 110 is equipped with an unlocking start component 130 and a door closing start component 140 that correspond one-to-one with the gate 120. When the unlocking start component 130 is in the start state, the control cabinet 110 generates an unlocking switch signal. When the door closing start component 140 is in the start state, the control cabinet 110 generates a door closing switch signal.

[0029] It should be noted that the unlocking start component 130 and the door closing start component 140 can be of various types, and no limitation is made here. The specific type can be determined according to the actual design requirements. For example, the unlocking start component 130 and the door closing start component 140 can be an unlocking button, an unlocking handle, etc.

[0030] It should be noted that, in order to prevent the continuous sending of the control cabinet unlock switch signal and the control cabinet door closing switch signal, the unlock start component 130 and the door closing start component 140 are automatic recovery components, that is, they can automatically return to the non-started state when in the start state.

[0031] The emergency door is used to perform an emergency door closing operation when it simultaneously receives the door closing switch signal and the unlocking switch signal from the corresponding unlocking start component 130 and the corresponding door closing start component 140.

[0032] By setting an unlocking start component 130 and a door closing start component 140 on the remote control cabinet 110, and setting it to perform an emergency door closing operation when the corresponding unlocking start component 130 and the corresponding door closing start component 140 send the control cabinet door closing switch signal and the control cabinet unlocking switch signal, the possibility of emergency door closing operation caused by human error or component failure can be reduced, thereby reducing the risk of safety accidents and property damage.

[0033] In this embodiment of the disclosure, the control cabinet 110 is provided with a first signal transmitting device corresponding to each gate and a second signal transmitting device corresponding to each gate. The first signal transmitting device is used to convert the control cabinet door closing switch signal into a door closing light signal, and the second signal transmitting device is used to convert the control cabinet unlocking switch signal into an unlocking light signal and send it to the gate 120.

[0034] It should be noted that an optical cable can be installed between the gate 120 and the control cabinet 110, and the gate closing optical signal and unlocking optical signal can be transmitted to the gate 120 through the optical cable. Compared with the disadvantages of traditional control cables, such as high cost, consumption of a lot of manpower and resources, easy damage, easy malfunction, low anti-interference ability, and cumbersome switching, the independent emergency door system in this disclosure uses optical signal transmission instead of hard-wired cable transmission. The advantage is that it avoids the risks of short circuit and malfunction after cable damage, grounding of DC power supply circuit, and reduced insulation that exist in long-distance outdoor transmission with hard-wired control cables.

[0035] It should be noted that the optical cable in this embodiment can be of various types, and no limitation is made here. For example, due to the long transmission distance, it can be a 12-core single-mode fiber, a 24-core single-mode fiber, a 48-core single-mode fiber, etc. The specific type can be limited according to the actual design requirements.

[0036] In this embodiment of the disclosure, the gate 120 is provided with a signal receiving device, which is used to receive the gate closing light signal and / or unlocking light signal, and convert them into gate closing switch signal and / or unlocking switch signal respectively. The first signal transmitting device and the second signal transmitting device correspond one-to-one with the first signal receiving device and the second signal receiving device, and are independent of each other.

[0037] In this embodiment of the disclosure, the door closing switch signal and the unlocking switch signal are processed to obtain a door closing command. In response to either the door closing switch signal or the unlocking switch signal being empty, the door closing command is empty.

[0038] In one possible implementation of this disclosure, such as Figure 2 As shown, when the first signal transmitting device and the second signal transmitting device are in normal working condition, and the remote unlocking start component 130 and the door closing start component 140 are in the start state, one contact of the relay switch of the signal receiving device is physically open; when the remote unlocking start component 130 and the door closing start component 140 are in the closed state, one contact of the relay switch of the signal receiving device is physically short-circuited.

[0039] It should be noted that, in order to ensure the normal operation of the control cabinet 110, the control cabinet 110 in this disclosure is powered by an uninterruptible power supply (UPS). Therefore, using a UPS for power supply can greatly reduce the safety risks caused by power supply abnormalities.

[0040] In this embodiment, the first signal transmitting devices of all gates 120 are connected to the UPS via a first switch, and the second signal transmitting devices of all gates 120 are connected to the UPS via a second switch. In one possible implementation of this disclosure, one AC 220V power supply line can be taken from each of sections A and B of the UPS power panel and connected to the AC input terminals of the two switching power supply modules in the operating cabinet 110 as the AC power input for the power modules. After rectification, the power modules output DC 24V power to supply the first and second signal transmitting devices respectively. The power supply for each gate-side signal receiving device is drawn from the gate local cabinet.

[0041] It should be noted that, in order to monitor the normal operation of the independent emergency gate system, the control cabinet 110 is equipped with a light path alarm device corresponding to each gate. When the signal transmitting device detects an abnormality in the light path, it generates an alarm signal, and the light path alarm device alarms based on the alarm signal.

[0042] The control cabinet 110 is equipped with a circuit alarm device that corresponds to each gate. When the control cabinet 110 detects a power abnormality, it generates an alarm signal, and the circuit alarm device alarms based on the alarm signal.

[0043] It should be noted that there are multiple alarm methods available, and no restrictions are imposed here. For example, light alarms and audible alarms are possible.

[0045] S301, monitors the signals sent by the control cabinet.

[0050] In this embodiment of the disclosure, the signal sent by the control cabinet is first monitored, and in response to simultaneously acquiring the control cabinet unlock switch signal and the control cabinet door closing switch signal sent by the control cabinet, an emergency door closing operation is performed.

[0051] By setting an emergency door-closing operation when both the corresponding unlocking and door-closing activation components and the corresponding door-closing activation components are simultaneously received, the possibility of an emergency door-closing operation due to human error or component malfunction can be reduced, thereby lowering the risk of safety accidents and property damage.
