Description

Technical Field

[0001] The present application relates to the technical field of electrical fire monitoring, and in particular to an integrated low-voltage protection and fire monitoring system. Background Art

[0002] An electrical fire detector is a detector that detects changes in electrical fire hazard parameters such as residual current and temperature in the protected circuit, and forms an electrical fire monitoring system through a communication network and electrical fire monitoring equipment. The electrical fire detector is used to send an alarm signal when the values ​​of hazardous parameters such as residual current or temperature exceed the set values. At the same time, the above hazardous parameter values ​​can also be transmitted to the electrical fire monitoring equipment, which then further identifies and determines them. When it is confirmed that a fire may occur, the monitoring host sends a fire alarm signal, lights up the alarm indicator light, and sounds an alarm.

[0003] Reference Figure 1 Each motor circuit drawer and distribution circuit drawer in a traditional low-voltage drawer-type switchgear is equipped with an electrical protection device. This electrical protection device includes at least a monitor for detecting circuit electrical data (such as a residual current transformer (CT) for detecting residual current) and a circuit protector (such as a motor protector) for protecting the circuit based on the electrical data. The circuit protector can also be electrically connected to a display to display the electrical data of the corresponding circuit. To monitor whether the motor circuit and distribution circuit present electrical fire risks, an electrical fire monitoring system can be added to the drawer-type switchgear. Specifically, the traditional low-voltage drawer-type switchgear can also be equipped with the electrical fire control system. The electrical fire detectors in the electrical fire control system are electrically connected to all monitors to receive and display fire-related electrical data (such as residual current data). The fire-related electrical data is then transmitted to the electrical fire monitoring system, which analyzes the residual current data and determines whether an alarm signal needs to be issued.

[0004] Since the judgment rules for electrical protection and the judgment rules for electrical fire risks are different, the electrical protection control device and the electrical fire monitoring system disclosed in the above-mentioned related technologies are independent of each other, and the electrical data of the corresponding circuit is displayed by a display external to the protector, and the electrical fire monitoring system displays the electrical data related to the fire based on the residual current. However, the separate display of the above two types of data is not convenient for patrol personnel to quickly query and obtain the corresponding electrical data and fire data, so it needs to be improved. Summary of the Invention

[0005] In order to achieve integrated monitoring of fire and electricity in the circuit, the present application provides an integrated low-voltage protection and fire monitoring system.

[0006] This application provides an integrated low-voltage protection and fire monitoring system, which adopts the following technical solutions:

[0007] An integrated low-voltage protection and fire monitoring system includes a circuit protector, a circuit detector, and a fire monitoring device. The circuit detectors and circuit protectors are arranged in a one-to-one correspondence with the circuits.

[0008] The circuit detector includes an electrical data detection module for acquiring electrical data in the corresponding circuit and sending the electrical data to the circuit protector;

[0009] The loop detector further includes a fire data monitoring module for acquiring fire data and sending the fire data to the fire monitoring device, wherein the fire data at least includes electrical data that is likely to cause fire;

[0010] The loop detector further includes an integrated display module, wherein the integrated display module is used to display the electrical data and the fire data;

[0011] The circuit protector is used to receive the electrical data and protect the corresponding circuit based on the electrical data;

[0012] The fire monitoring equipment is used to receive and analyze the fire data, and when the fire data reaches a preset alarm condition, output a fire alarm signal that can be notified to corresponding patrol personnel.

[0013] By adopting the above technical solution, the loop detector is used to obtain the electrical data in the loop and the fire data that is likely to cause fire during the operation of the loop. The loop detector is then used to send the electrical data to the loop protector, so that the loop protector can protect the loop based on the electrical data. The loop detector also sends the fire data to the fire monitoring equipment for analysis, so as to issue a fire alarm signal when the alarm conditions are met. In addition, the loop detector of the present application can also display electrical data and fire data in an integrated manner, so that patrol personnel can easily query electrical data and fire data on the same device.

[0014] Preferably, the integrated display module is further configured to verify the identity information of the initiator of the query instruction upon receiving the query instruction, and determine the query scope of the electrical data and / or fire protection data available for query by the initiator based on the identity information.

[0015] By adopting the above technical solution, different query permissions are granted to different initiators by verifying identity information and limiting the query scope, thereby improving data security.

[0016] Preferably, the integrated display module is further configured to switch and display data corresponding to the switching signal upon receiving the switching signal, wherein the data is fire data or electrical data;

[0017] The loop detector also includes a detection control module, which is used to obtain the electrical data obtained by the electrical data detection module and the fire data obtained by the fire data monitoring module, and based on preset electrical specifications and preset fire specifications, determine whether the electrical data and fire data are abnormal, and in the event of an abnormality, generate a switching signal with abnormal electrical data and / or abnormal fire data, and send the switching signal to the integrated display module.

[0018] By adopting the above technical solution, the switching display of fire data and electrical data is realized, and this solution provides one of the trigger conditions for triggering the switching display, that is, based on the latest acquired electrical data and fire data, it is determined whether there is abnormal electrical data or fire data. If so, a switching signal with abnormal electrical data and / or abnormal fire data is generated, so that the integrated display module switches the display page and displays the above abnormal electrical data and / or abnormal fire data in a targeted manner.

[0019] Preferably, the integrated low-voltage protection and fire monitoring system further comprises a management and control platform, the fire monitoring device and the circuit protector are both electrically connected to the management and control platform, the fire monitoring device is used to send fire data to the management and control platform, and the circuit protector is used to send electrical data to the management and control platform;

[0020] The control platform is pre-built with a three-dimensional model diagram for displaying the positional relationship and position information between all loops, and the control platform is communicatively connected to the mobile terminal of the inspection personnel;

[0021] The control and management platform is also used to receive online query instructions issued by the mobile terminal of any patrol personnel, and send a three-dimensional model diagram to the mobile terminal of the patrol personnel for selection of the circuit to be queried; the control and management platform is also used to receive selection instructions, and send electrical data and / or fire protection data of the circuit corresponding to the selection instruction to the mobile terminal of the patrol personnel who initiated the selection instruction.

[0022] By adopting the above technical solution, when there are multiple inspectors who want to query the electrical data and / or fire data of the same circuit, since the offline query method using the display interface of the fire detector cannot meet the simultaneous query of multiple people, a method is provided for sending a three-dimensional model diagram to the mobile terminal of the inspector online, so that the inspector can select the circuit to be queried to trigger the selection instruction, and display the electrical data and / or fire data of the circuit corresponding to the selection instruction, thereby further realizing convenient query of the data.

[0023] Preferably, the fire monitoring equipment is used to receive and analyze the fire data, and when there is first fire data that meets the preset alarm conditions, based on the location information of the circuit corresponding to the first fire data, predict the fire range where there is a fire risk, and add the fire range to the fire alarm signal.

[0024] By adopting the above technical solution, when a fire hazard exists in one of the circuits (i.e., the preset alarm conditions are met), other circuits are easily affected and implicated, resulting in fire risks. Therefore, the fire protection range refers to the sum of all circuit locations with fire risks caused by a fire hazard in any circuit, so that inspection personnel can deploy fire protection plans in advance based on the fire protection range.

[0025] Preferably, the fire data also includes temperature data; the fire monitoring equipment is used to determine the first circuit corresponding to the first fire data when predicting the fire range, and based on the position information of the first circuit and the pre-stored position relationship of all relevant circuits, determine the second circuit adjacent to the first circuit, compare the temperature data of the first circuit with the temperature data of the second circuit and obtain the similarity, and if there is a second circuit with a similarity greater than a preset similarity, generate a fire range, wherein the fire range at least includes the position information of the first circuit and the position information of the second circuit with a similarity greater than the preset similarity.

[0026] By adopting the above technical solution, when a circuit catches fire, the fire is likely to spread, and the circuits adjacent to the circuit in the physical environment where the circuit is located are also likely to be affected, thereby expanding the fire range. Therefore, this solution will use temperature data as a way to determine whether the adjacent circuits will be affected to determine the fire range.

[0027] Preferably, the fire monitoring device is used to store historical records of all circuits triggering fire alarm signals in historical periods, and is also used to obtain and store the secondary circuit corresponding to each circuit, where the secondary circuit corresponding to the target circuit refers to a circuit that is affected by the target circuit and thus has a fire risk when the target circuit has a fire risk, wherein the target circuit refers to any circuit;

[0028] The fire monitoring device is used to combine the position information of the circuit corresponding to the first fire data and all the secondary circuits of the circuit corresponding to the first fire data to generate a fire range when predicting the fire range.

[0029] By adopting the above technical solution, the historical record of the circuit triggering the fire alarm signal in the historical period refers to the historical record of the actual fire occurring in the historical period. The fire monitoring equipment can obtain the secondary circuit corresponding to each circuit based on this historical record. The specific acquisition method can be: display the above historical records to the inspection personnel, and the inspection personnel determine and feedback the secondary circuit corresponding to each circuit based on the historical record analysis, and then the fire monitoring equipment stores the above correspondence, so that when any circuit has a fire risk again in the future, the fire protection scope can be determined based on the correspondence.

[0030] Preferably, the fire monitoring device is further configured to determine the risk level of each secondary circuit, and based on the risk level, differentiate and display the location information of each secondary circuit within the fire protection range.

[0031] By adopting the above technical solution, the risk level is used to characterize the possibility of fire caused by the involvement of the secondary circuit, and by determining the risk level, a further accurate prediction of the fire range can be achieved.

[0032] Preferably, the preset alarm condition includes several reference dimensions, and a warning threshold and an alarm threshold corresponding to each reference dimension, and the warning threshold of the same reference dimension is less than the alarm threshold;

[0033] The fire monitoring device is configured to, when receiving and analyzing fire data, obtain second fire data corresponding to the reference dimension from the fire data, and compare the second fire data with a corresponding alarm threshold; if any second fire data exceeds the corresponding alarm threshold, it is considered that a preset alarm condition is met, and a fire alarm signal is generated at this time, and the corresponding second fire data is added as risk data to the corresponding fire alarm signal, and the corresponding reference dimension is determined as the risk dimension;

[0034] The fire monitoring device is used to obtain third fire data corresponding to each risk dimension from the fire data of the secondary circuit when determining the risk level of each secondary circuit, and compare the third fire data with the corresponding warning threshold. If the third fire data exceeds the corresponding warning threshold, it is considered that the warning condition of the corresponding risk dimension is met; the fire monitoring device is used to determine the number of warnings for each secondary circuit that meets the warning condition of the risk dimension, and determine the risk level based on the number of warnings, where the larger the number of warnings, the higher the risk level.

[0035] By adopting the above technical solution, when the fire monitoring equipment analyzes the received fire data to determine whether it meets the preset alarm conditions, the corresponding specific determination method is: filter out the fire data corresponding to the preset reference dimension (i.e., the second fire data) from the fire data, and then compare the second fire data with the alarm threshold preset by the corresponding reference dimension. If the alarm threshold is exceeded, it is considered that the preset alarm condition is met, the corresponding reference dimension is the risk dimension, and the corresponding circuit has a fire risk. At this time, when determining the secondary circuit of the circuit and determining the risk level of the secondary circuit, the fire data of the secondary circuit will be compared first. Find the alarm data corresponding to the risk dimension in the data (i.e., the third fire data), and determine whether the third fire data meets the warning conditions (i.e., whether it is greater than the warning threshold corresponding to the risk dimension). If so, determine the number of data that meet the warning conditions (i.e., the number of warnings). For example, if there are three risk dimensions A, B, and C, and among the third fire data a, b, and c corresponding to the above three risk dimensions in the secondary circuit, only the third fire data a is greater than the warning threshold corresponding to the risk dimension A, then the number of secondary circuits that meet the warning conditions (i.e., the number of warnings) is 1. The number of warnings can be used to characterize the risk level of fire in the secondary circuit.

[0036] Preferably, the fire monitoring equipment is used to send a high-frequency monitoring instruction with a fire range to the loop detector after determining the fire range; the loop detector is used to increase the frequency of acquiring electrical data and fire data of the loop corresponding to the fire range.

[0037] By adopting the above technical solution, high-frequency monitoring and analysis of electrical data and fire data of all circuits within the fire protection range can be achieved to ensure timely knowledge of fire situations.

[0038] In summary, this application has the following beneficial technical effects:

[0039] The loop detector is used to detect the electrical data and fire data of the loop, and the electrical data and fire data are displayed in an integrated manner. The loop detector is then used to send the electrical data to the loop protector and the fire data to the fire monitoring equipment. The loop is protected based on the electrical data by the loop protector. The fire data is received and analyzed by the fire monitoring equipment. When the fire data reaches the preset alarm condition, a fire alarm signal is output to inform the corresponding patrol personnel, thereby realizing the dual functions of fire alarm and electrical protection. In addition, the management and control platform can centrally store the aforementioned fire data, electrical data, analysis results of the fire monitoring equipment, and status operation data of the loop protector.

[0044] The following is combined with Figure 2-3 This application is described in further detail.

[0045] The present application discloses an integrated low-voltage protection and fire monitoring system. The integrated low-voltage protection and fire monitoring system is suitable for monitoring the operating status of circuits within each circuit drawer of a low-voltage drawer-type switchgear. The operating status may specifically refer to electrical data and the presence of fire risks, so that timely protective measures can be taken for the circuits based on the monitoring results. The circuits may specifically include motor circuits, power distribution circuits, etc.

[0046] Specifically, refer to Figure 2 The integrated low-voltage protection and fire monitoring system includes a circuit protector 2 and a circuit detector 1 that are arranged in a one-to-one correspondence with the circuit, and also includes a fire monitoring device 3 and a control platform 4. Among them, the circuit in the embodiment of the present application can be a motor circuit, and the corresponding circuit protector 2 can be a motor circuit protector 2. The circuit detector 1 is electrically connected to the circuit protector 2, and the circuit detector 1 is communicatively connected to the fire monitoring device 3. The fire monitoring device 3 and the circuit protector 2 are both communicatively connected to the control platform 4. In other embodiments, for a circuit drawer whose circuit is a power distribution circuit, the circuit detector 1 and the circuit protector 2 can be integrated into an independent device (such as Figure 2 distribution line protection device shown).

[0047] Reference Figure 2 and Figure 3The loop detector 1 is used to obtain and display the electrical data and fire data of the loop, and is also used to send fire data to the fire monitoring device 3 so that the fire monitoring device 3 can determine whether to issue a fire alarm; the loop detector 1 is also used to send electrical data to the loop protector 2 so that the loop protector 2 can protect the loop based on the electrical data. The management and control platform 4 is used to obtain and store the fire data received by the fire monitoring device 3, as well as the analysis results of the fire monitoring device 3. It is also used to obtain the electrical data received by the loop protector 2, as well as the operating data of the loop protector 2, and can also provide a function for patrol personnel to retrieve all the aforementioned stored data.

[0048] In other embodiments, the electrical data also includes operating data of the circuit protector 2, so that the fire detector can be used as a display medium for the circuit protector 2. Furthermore, the fire protection data specifically includes electrical data that is likely to cause fires (such as residual current and voltage data) and other detection data that is likely to cause fires (such as temperature data and carbon dioxide concentration data). The circuit detector 1 can obtain the above data by electrically connecting the circuit detector 1 to a monitor pre-installed in the circuit drawer. Detection components can specifically include current transformers, voltage transformers, temperature sensors, carbon dioxide concentration sensors, leakage current transformers (CTs), and the like.

[0049] Reference Figure 2 and Figure 3 Specifically, the circuit detector 1 includes an electrical data detection module 11, a fire data monitoring module 12, an integrated display module 13, and a detection control module 14. The electrical data detection module 11 is used to acquire electrical data in the corresponding circuit based on the acquisition method mentioned above and at a preset acquisition frequency, and send the electrical data to the circuit protector 2 and the integrated display module 13 respectively. It is also used to send electrical data related to the fire (hereinafter collectively referred to as the first electrical data) to the fire data monitoring module 12. The fire data monitoring module 12 is used to receive the first electrical data, and based on the acquisition method mentioned above and at a preset acquisition frequency, acquire detection data in the corresponding circuit, merge the first electrical data with the detection data to generate fire data, and send the fire data to the fire monitoring device 3 and the integrated display module 13 respectively.

[0050] Reference Figure 2 and Figure 3The integrated display module 13 is used to display electrical data and fire data. The display mode can be to display electrical data and fire data simultaneously on the same display interface, or to display electrical data and fire data separately on different display interfaces. The display interface is switched upon receiving a switching signal. The switching signal can be generated by the inspection personnel touching a switching button preset on the surface of the loop detector 1. There can be two switching buttons, that is, corresponding one to one with two display interfaces, so that the integrated display module 13 displays the display interface corresponding to the switched model based on the correspondence between the switching buttons and the display interfaces, and then displays the data on the corresponding display interface.

[0051] In addition, the embodiment of the present application also provides another method for generating a switching model: the detection control module 14 is used to obtain electrical data and fire data according to a preset acquisition frequency, and based on the preset electrical specifications and fire specifications, determine whether the electrical data and fire data are abnormal, and when abnormal, generate a switching signal with abnormal electrical data and / or abnormal fire data, and send the switching signal to the integrated display module 13, so that the integrated display module 13 displays the abnormal electrical data and / or abnormal fire data contained in the switching signal. Among them, the specific method for determining whether the electrical data and fire data are abnormal based on the preset electrical specifications and fire specifications can be: compare the electrical data and fire data with the preset corresponding threshold value, and if the corresponding threshold value is exceeded, it indicates an abnormality.

[0052] Reference Figure 2 and Figure 3 The integrated display module 13 is also used to verify the identity information of the initiator of the query instruction upon receiving the query instruction, and determine the query scope of the electrical data and / or fire protection data available to the initiator based on the identity information. Specifically, the initiator of the query instruction can be an inspection personnel, and the query instruction will be divided into online query instructions and offline query instructions based on the initiator's initiation method. Offline query instructions refer to querying by operating the display screen of the loop detector 1, and online query instructions refer to querying by submitting an online query instruction to the management and control platform 4 using a smart terminal (such as a PC or mobile phone). The initiator's identity information includes at least a position (such as a firefighter or electrical maintenance personnel). In addition, the query instruction may also include search keywords to further narrow the query scope. The search keywords may specifically include time, loop location information, etc.

[0053] In addition, a three-dimensional model diagram is pre-built in the management and control platform 4. The three-dimensional model diagram is used to display all the circuit drawers in the low-voltage drawer-type switch cabinet in the form of a three-dimensional diagram, and display the corresponding location information. The location information may include the geographical location of the low-voltage drawer-type switch cabinet and the location information of the circuit in the pressure drawer-type switch cabinet (such as row and column information); the management and control platform 4 is used to send the three-dimensional model diagram to the corresponding initiator when receiving the online query instruction, so that the initiator can select the circuit to be queried. The selection method can be to touch the specific location in the corresponding three-dimensional model diagram to select, or to enter the location information of the circuit to be queried to select, and to add search keywords to finally trigger the generation of the selection instruction. Accordingly, the management and control platform 4 will retrieve the electrical data and / or fire protection data of the circuit corresponding to the selection instruction and send it to the corresponding initiator's smart terminal.

[0054] Reference Figure 2 and Figure 3 Fire monitoring device 3 stores preset alarm conditions, which include several reference dimensions (such as residual current and temperature), as well as the corresponding alarm thresholds for each reference dimension. Fire monitoring device 3 is configured to receive and analyze fire data. Specifically, fire monitoring device 3 obtains fire data corresponding to each reference dimension (hereinafter referred to as second fire data) from the received fire data and compares the second fire data with the alarm thresholds for the corresponding reference dimensions. If any second fire data exceeds the corresponding alarm threshold, the second fire data is deemed to meet the preset alarm conditions, thereby completing the analysis.

[0055] The fire monitoring device 3 is used to generate a fire alarm signal after completing the analysis operation and when the first fire data exists, and the first fire data is added to the corresponding fire alarm signal as risk data, and the corresponding reference dimension is determined as the risk dimension.

[0056] The fire monitoring device 3 is also configured to, when generating a fire alarm signal, predict the fire risk range based on the location information of the circuit corresponding to the first fire data, add this fire risk range to the fire alarm signal, and finally issue the fire alarm signal so that patrol personnel can be notified of the fire alarm signal, such as by sending the fire alarm signal to the smart terminals of all patrol personnel. Simultaneously, the fire monitoring device 3 also sends the fire alarm signal to the detection control module 14. Upon receiving the fire alarm signal, the detection control module 14 is configured to determine the detection source (the detection source being the electrical data detection module 11 or the fire data monitoring module 12) for acquiring the risk data based on the risk data in the fire detection alarm signal, and to send a high-frequency monitoring instruction to the detection source, causing the corresponding detection source to increase its preset acquisition frequency to a specified frequency value and, starting at the current moment, acquire data corresponding to the risk data at the specified frequency value.

[0057] The fire protection range at least includes the location information of the circuit corresponding to the first fire protection data. In addition, this application provides two methods for predicting the fire protection range, which are disclosed as follows:

[0058] Method 1: The fire monitoring device 3 is used to determine the first circuit corresponding to the first fire data, and based on the position information of the first circuit and the pre-stored position relationship of all circuits, determine the second circuit adjacent to the first circuit, compare the temperature data of the first circuit with the temperature data of the second circuit and obtain the similarity. If there is a second circuit with a similarity greater than the preset similarity, the position information of the second circuit is included in the fire range. Among them, the position relationship is pre-set and stored, specifically including the adjacent relationship and the electrical connection relationship. The adjacent relationship refers to the adjacent row and column positions in the low-voltage drawer-type switch cabinet, and the electrical connection relationship refers to the existence of a line connection relationship such as series or parallel between the two circuits; the similarity can be reflected by the difference between the temperature data of the first circuit and the second circuit. The smaller the difference, the greater the similarity; the fire range can be reflected in the form of an image, and the image specifically includes the first circuit, the second circuit with a similarity greater than the preset similarity, and its position in the low-voltage drawer-type switch cabinet, as well as the position information.

[0059] Method 2: Whenever a fire alarm signal is generated, the fire monitoring device 3 stores a historical record corresponding to the fire alarm signal. The historical record includes the first fire data, the location information of the first circuit, and the time the fire alarm signal was generated. The fire monitoring device 3 can send the historical records generated within a specified historical period (e.g., daily) to the patrol personnel's mobile terminal for logging. The patrol personnel's mobile terminal can then record the log. The log content includes at least the cause of the fire, the existence of a secondary circuit, and the location information of the corresponding secondary circuit. A secondary circuit is a circuit that is affected by the first circuit and thus presents a fire risk when a fire alarm signal is issued due to a fire risk in the first circuit. The fire monitoring device 3 receives the log feedback from the patrol personnel and stores the corresponding relationship between the circuit and its corresponding secondary circuit. Accordingly, the fire monitoring device 3 includes the location information of all secondary circuits stored for the circuit corresponding to the first fire data (i.e., the first circuit) within the fire protection scope.

[0060] Reference Figure 2 The fire monitoring device 3 is also used to determine the risk level of each secondary circuit after determining the secondary circuit corresponding to the first circuit, and distinguish the location information of each secondary circuit within the fire protection range according to the risk level, such as distinguishing by different colors or displaying the font size of the location information. The greater the risk level, the darker the corresponding display color or the larger the font size.

[0061] Specifically, the preset alarm conditions also include the warning threshold corresponding to each reference dimension, and the warning threshold corresponding to the same reference dimension is less than the corresponding alarm threshold. The risk level of each secondary loop is determined as follows: the fire monitoring device 3 is used to obtain the third fire data corresponding to each risk dimension from the fire data of the secondary loop, and compare the third fire data with the warning threshold of the corresponding risk dimension. If the third fire data exceeds the corresponding warning threshold, it is considered that the warning condition of the corresponding risk dimension is met; the fire monitoring device 3 is used to determine the number of warnings that meet the warning conditions of the risk dimension for each secondary loop, and determine the risk level based on the number of warnings, where the larger the number of warnings, the higher the risk level. Among them, the value range of the number of warnings determined by a single secondary loop is: 0≤number of warnings≤number of risk dimensions.

[0062] The implementation principle of an integrated low-voltage protection and fire monitoring system in an embodiment of the present application is: using a loop detector 1 to detect the electrical data and fire data of the loop, and display the electrical data and fire data in an integrated manner, then using the loop detector 1 to send the electrical data to the loop protector 2, and send the fire data to the fire monitoring equipment 3, the loop protector 2 protects the loop based on the electrical data, the fire monitoring equipment 3 receives and analyzes the fire data, and when the fire data reaches the preset alarm condition, outputs a fire alarm signal that can be notified to the corresponding patrol personnel, thereby realizing the dual functions of fire alarm and electrical protection. In addition, the management and control platform 4 can centrally store the aforementioned fire data, electrical data, analysis results of the fire monitoring equipment 3, and status operation data of the loop protector 2, so that the patrol personnel can retrieve and view the aforementioned stored information when they subsequently visit the management and control platform 4.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
