Description

Technical Field

[0001] The utility model relates to an RGL cabinet, in particular to an earthquake-resistant RGL cabinet. Background Art

[0002] As the primary controller for reactor reactivity control, the RGL system is one of the most critical specialized instrumentation and control systems in a nuclear power plant. Its operational status directly impacts the reactor's normal operation. During startup, power conversion, and shutdown, the RGL system controls the control rod drive mechanism (CRDM) to raise, lower, and retain control rods, enabling normal power regulation or shutdown. It also monitors and indicates the height of the control rods within the core, facilitating on-site inspection and maintenance. This demonstrates the importance of the RGL cabinet.

[0003] Publication No. CN 208227517 U discloses a new RGL cabinet, comprising a welded frame consisting of a top cover, columns, and base. The left and right sides of the frame feature waterproof bends. The front and rear facades of the frame are protected with silver-based conductive paint where they contact the conductive shielding strips on the front and rear doors. Conductive shielding strips are installed during assembly of the left and right panels, front and rear doors. The top cover is connected to a waterproof cover, and a central opening in the top cover with an upwardly folded vertical edge securely connects to the waterproof cover. This allows water flowing from the waterproof cover to reach the top cover, where it is blocked by the folded vertical edge and naturally flows out of the cabinet. This design addresses the complex structure and low seismic resistance of conventional cabinets, while also providing electromagnetic shielding, protecting the cabinet's internal electrical components from external interference. It also offers excellent ventilation and heat dissipation.

[0019] The beneficial effects of the utility model are:

[0020] 1. The present invention combines an anti-seismic device, columns, and multiple chassis with sliders within a frame, ensuring that the multiple chassis are parallel to the base. Furthermore, when the base tilts at a certain angle due to vibration, the angle between the lower and upper bases of the anti-seismic device also changes. The side with a smaller angle deforms the elastic component due to the clamping force between the lower and upper bases (while the elastic component can also relieve some kinetic energy). Furthermore, multiple limiting fixing blocks are sleeved on the sliding columns (i.e., the columns and the sliding columns are parallel to each other and can generate axial displacement). , the chassis is mounted on the sliding column through a slider. During the tilting process due to vibration, the limiting fixed block and the slider slide up and down on the sliding column with the frequency of the vibration (the top cover is buckled on the frame and is not installed by welding. When vibration occurs, the column can be displaced together with the top cover and separated from the frame), so that the chassis maintains a relatively horizontal position, effectively solving the problem of mechanical damage to the chassis caused by the pulling force of the frame on the chassis when vibration occurs, effectively protecting the integrity of the electrical components in the chassis, improving the seismic performance of the new model, and expanding the scope of application of the new model.

[0021] 2. The utility model provides a human-machine interface control device, allowing the operator to operate the human-machine interface control device through an operation button to achieve control of the RGL system. At the same time, the RGL system can be monitored and adjusted in real time through the display screen, reducing the tools required by the operator during operation, that is, reducing the operator's load, improving the operator's work efficiency and the accuracy of the RGL system regulation, making the operation of the utility model more convenient during use, and improving the practicality of the utility model.

[0022] 3. The utility model combines the seismic base with an upper base provided with an arc-shaped rotating protrusion and a lower base provided with a column, so that when the seismic base is subjected to vibration, the upper base and the lower base can tilt at a certain angle. After tilting, a clamping force is generated between the upper base and the lower base, which causes the elastic component to deform. The rebound force of the elastic component is used to absorb and relieve part of the kinetic energy, thereby reducing the impact of vibration on the box body, reducing the situation where mechanical damage to the box body caused by vibration affects the normal operation of electrical components, improving the seismic performance of the utility model, and expanding the scope of application of the utility model.

[0023] 4. The utility model reduces the corrosive effects of water vapor and dust in the external natural environment on the elastic component during use by arranging a telescopic tube sleeve on the outer periphery of the elastic component, thereby extending the service life of the elastic component. At the same time, the arrangement of multiple fixed plates extending outward from the column and connected to the telescopic tube sleeve achieves the technical effect of limiting the relative position of the elastic component (i.e., preventing the elastic component from undergoing horizontal displacement, thereby affecting the shock absorption effect). At the same time, it can also ensure that the top surface of the elastic component is always connected to the lower surface of the upper base, so that the bottom surface of the elastic component can maintain a certain distance from the upper surface of the lower base, which is convenient for the subsequent installation of signalers and sensors, thereby improving the safety of the utility model and expanding the scope of application of the utility model.

[0024] 5. The utility model is equipped with an anti-seismic controller and a battery embedded in the column, which can analyze the signals fed back by the signal device and the sensor, and transmit them to the controller after analysis. The controller further responds to the vibration emergency, reduces the vibration emergency time, and improves the efficiency of the operator in starting the emergency plan. At the same time, it can assist the staff in positioning, solving the problem of missing the best repair time due to checking a large number of cabinets one by one or causing production accidents due to untimely repairs.

[0025] 6. The utility model can maintain voltage stability through the transformer board arranged in the equipment room, thereby improving the stability and safety of the operation of electrical components in the cabinet. At the same time, a battery is also arranged in the equipment room, and the battery is connected to the transformer. Normally, a certain amount of electrical energy is stored in the battery. When vibration occurs, it is often accompanied by a power outage. When power is on, the battery in the equipment room can provide a certain amount of electrical energy for the display screen and the controller, ensuring that the utility model can operate normally for a certain period of time, providing the operator with time for emergency operation, and preventing economic losses and casualties caused by the inability to adjust and operate the RGL system. The practicality of the utility model is improved and the scope of application of the utility model is expanded.

[0026] 7. The present invention provides a heat dissipation component in the equipment room and physically cools the equipment room through multiple sets of heat dissipation fans, thereby effectively solving the problem of damage to the transformer and controller or shortening the service life of the transformer and controller due to self-heating during operation. It also solves the problem of damage to the battery and shortening the service life of the battery due to high temperature in the equipment room, effectively extending the service life of the transformer and battery, reducing repair and maintenance costs, and improving the practicality of the present invention.

[0027] 8. The utility model sets a counterweight block inside the fixed block to ensure that when in use, the upper base of the shock-absorbing base can remain relatively parallel to the lower base, preventing the upper base from tilting due to uneven force, so that the signal device and the sensor will not be accidentally touched or reported in the absence of vibration, and multiple elastic components can always maintain a naturally stretched state, effectively preventing the problem of some elastic components being in a compressed state due to tilted compression of the elastic components, thereby causing elastic fatigue of the elastic components in this part, affecting the shock-absorbing effect, extending the service life of the elastic components, improving the accuracy of vibration detection of the utility model, and improving the practicality of the utility model.

[0042] The specific working principle is:

[0043] When in use, the columns are installed on the base through the anti-seismic device, and the left side plate, right side plate, rear door, front door and top cover are arranged around the multiple columns, so that the left side plate, right side plate, rear door, front door and top cover form a rectangular structure frame (the frame is connected to the base through the columns and the anti-seismic device), and the sliding rods extended upward by the anti-seismic device are equipped with limit fixing blocks connected to the columns and sliders located on both sides of the chassis. The top ends of the multiple sliding rods are connected to the connecting rods, and the connecting rods are connected end to end to form a rectangular structure. At the same time, because the end-to-end connections of the multiple connecting rods are rotating connections Therefore, multiple connecting rods can produce relative displacement (that is, the angle between the connecting rod and the sliding column becomes larger or smaller). Since the anti-seismic device is an I-shaped structure composed of an upper base and a lower base, the upper base and the lower base of the anti-seismic device can be kept parallel to each other by adjusting the position or weight of the counterweight block in the limiting fixed block. At the same time, since the bottom surface of the chassis at the bottom layer is in contact with the top surface of the equipment room, the equipment room bears most of the weight of the chassis, which greatly reduces the force borne by the anti-seismic device and makes it easier for the upper base and the lower base of the anti-seismic device to remain parallel to each other.

[0044] When vibration occurs, the base of the cabinet will vibrate accordingly. At this time, the angle between the upper base and the lower base of the earthquake-resistant base will also change accordingly. The multiple elastic components arranged around the earthquake-resistant base will be squeezed and deformed, and the resilience of the elastic components will be used to remove part of the vibration force. Due to the deformation, the signal device at the top of the elastic component and the sensor on the lower base will contact and connect with each other. After receiving the signal, the sensor will transmit it to the earthquake-resistant controller. The earthquake-resistant controller will start the emergency program and send a signal to the controller. The controller will send an alarm to the terminal in the control room to remind the operator to take emergency measures in time to prevent the occurrence of secondary disasters.

[0045] When a large vibration occurs, the base will not only vibrate but also tilt at a certain angle (i.e., it will tilt left and right or the base of the cabinet will tilt due to a certain tilt of the ground). At this time, the angle between the lower base and the upper base will also change. The elastic component on the side with a smaller angle will be deformed due to the clamping force between the lower base and the upper base (the rebound force of the elastic component can offset and alleviate part of the force generated by the vibration). At the same time, the signaler at the top of the elastic component is in contact with and connected to the sensor on the lower base. After receiving the signal, the sensor transmits it to the anti-seismic controller. The anti-seismic controller starts the emergency procedure, sends a signal to the controller, and cuts off the power supply of the RGL cabinet after a certain period of time to prevent fire. The controller sends an alarm to the terminal in the control room to remind the operator The operating personnel take emergency measures in time to prevent the occurrence of secondary disasters; and multiple columns are mounted on the sliding columns through limit fixing blocks, and the chassis is mounted on the sliding columns through sliders. During the tilting process, the relative positions of the limit fixing blocks and the sliders remain unchanged (the top cover is buckled on the frame and is not welded. When vibration occurs, the columns can be displaced together with the top cover, while the positions of the limit fixing blocks and the sliders remain basically horizontal) the sliding columns slide up and down in the limit fixing blocks and the sliders with the frequency of the base vibration, and the chassis basically does not tilt, effectively preventing the chassis from being damaged due to the tilting or vibration of the frame, thereby causing damage to the chassis, and thus causing damage to and failure of the electrical components in the chassis, effectively protecting the integrity and functionality of the electrical components in the chassis.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
