Description

Technical Field

[0001] This application relates to the field of electrical technology, and more specifically, to a switch cabinet and an electric mining car. Background Technology

[0002] A switchgear is a combination of electrical equipment used in power systems for power distribution, control, and protection. Classified by application, switchgear includes receiving cabinets and feeder cabinets. A receiving cabinet is a cabinet that receives electrical energy; its main function is to open, close, control, and protect electrical equipment during power transmission, distribution, and energy conversion. A feeder cabinet's main function is to distribute electrical energy, acting like a "power distributor," rationally allocating the electrical energy received from the receiving cabinet to different areas, equipment, or lines.

[0003] Typically, the receiving cabinet is installed at the input end of the power system, responsible for receiving electrical energy from an external power source and providing power to the system. The feeder cabinet distributes and transmits the electrical energy received from the receiving cabinet to various electrical devices, controlling, protecting, and monitoring the branches distributed to each device to ensure their normal operation. In existing technology, to meet the diverse power needs of electric mining trucks, various types of switchgear need to be installed on them, such as receiving cabinets and feeder cabinets. However, electric mining trucks are prone to shaking and bumping during transportation, causing slight tilting of the switchgear installed on them. Prolonged tilting can affect the normal operation of the electrical equipment within the switchgear, and this slight tilting is difficult for workers to detect in a timely manner.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0046] like Figures 1 to 4As shown, this application provides a switch cabinet. The switch cabinet includes a cabinet body 10 and a control assembly 20. The cabinet body 10 is at least mounted on an electric mining car. The control assembly 20 includes a controller 21, a tilt detection component 22, and a feedback component 23. The controller 21 and the tilt detection component 22 are mounted on the cabinet body 10. The tilt detection component 22 is electrically connected to the controller 21 and is used to detect the tilt angle of the cabinet body 10 relative to a horizontal plane. The horizontal plane is the horizontal plane where the electric mining car is located. The feedback component 23 is mounted on the cabinet body 10 and is electrically connected to the controller 21.

[0047] In this embodiment, during the transportation of the electric mine truck, the shaking and bumping of the truck can easily cause the switchgear to tilt. This embodiment addresses this by installing a tilt detection component 22 on the cabinet 10. This component can promptly detect the tilt angle of the cabinet 10 relative to the horizontal plane, ensuring that personnel can detect the tilting phenomenon in a timely manner and effectively preventing damage to the electrical equipment inside the switchgear due to prolonged tilting. Simultaneously, the tilt detection component 22 transmits the detected tilt angle to the controller 21, which can immediately issue a warning to the personnel via the feedback component 23. This ensures that personnel can promptly detect the tilting phenomenon, significantly shortening the time from the occurrence of tilting to its detection and effectively improving the switchgear's response efficiency to tilting. By promptly detecting and warning of switchgear tilting, this embodiment provides early warning of potential switchgear malfunctions, allowing personnel to intervene before the tilting problem becomes severe, ensuring the stable operation of the electrical equipment inside the switchgear.

[0048] Furthermore, the tilt detection component 22 includes a mounting plate 221 and an angle detection element. The mounting plate 221 is fixed inside the cabinet 10. The angle detection element is mounted on the mounting plate 221 and electrically connected to the controller 21. The angle detection element is used to transmit the detected tilt angle to the controller 21.

[0049] Mounting plate 221 is securely fixed inside cabinet 10, ensuring reliable stability. As a supporting structure for the angle detection element, mounting plate 221 provides stable support. Even if cabinet 10 is subjected to shaking or bumps, mounting plate 221 ensures the relative stability of the angle detection element, guaranteeing accurate and stable detection of the tilt angle of cabinet 10 relative to the horizontal plane. This effectively reduces detection errors caused by the element's own shaking or displacement, improving detection accuracy. Simultaneously, the electrical connection between the angle detection element and controller 21 ensures that the tilt angle detected by the element is transmitted to controller 21 promptly and accurately, enhancing the reliability of control component 20.

[0050] Specifically, after the angle detection device transmits the detected tilt angle to the controller 21, if the tilt angle received by the controller 21 is greater than the preset safety range, the controller 21 can control the feedback device 23 to issue a warning to the staff, so as to promptly remind the staff that the switch cabinet has tilted.

[0051] Furthermore, the angle detection component includes at least one of a tilt sensor, a gravity sensor, a gyroscope, and a laser inclinometer. The tilt sensor can directly measure the tilt angle of the cabinet 10 relative to the horizontal plane. The tilt sensor has high measurement accuracy; when the electric mining car is moving smoothly, the tilt sensor can accurately measure the tilt angle of the cabinet 10 relative to the horizontal plane, providing reliable data for the subsequent judgment and processing by the controller 21. In addition, the tilt sensor is easy to integrate and install in the switch cabinet and electrically connect to the controller 21, simplifying installation and reducing installation difficulty.

[0052] The gravity sensor detects the tilt angle of cabinet 10 relative to the horizontal plane by sensing changes in the direction of gravity. The gravity sensor can detect the tilt angle of the switchgear during transportation in real time, and is highly sensitive to minute tilt changes. When the electric mining truck encounters slight bumps or minor tilts, the gravity sensor can quickly capture these slight tilt changes of cabinet 10, providing a more accurate reflection of the switchgear's tilt status. The gravity sensor also has a fast response speed, enabling it to detect the tilt angle of cabinet 10 relative to the horizontal plane in real time and transmit the tilt angle to controller 21 more promptly. Furthermore, the gravity sensor is small in size, lightweight, and consumes little power, making it suitable for installation in switchgear where space is limited.

[0053] Gyroscopes possess high rotational stability. They can accurately measure the dynamic changes in the tilt of the switchgear 10. When the electric mining truck suddenly turns, accelerates, or decelerates, causing the switchgear to shake violently, the gyroscope can record information such as changes in the tilt angle, making it easier for the controller 21 to analyze the switchgear's tilt under complex motion conditions. Gyroscopes are also suitable for extreme environments such as low and high temperatures and have excellent vibration and shock resistance, making them suitable for installation in equipment operating under harsh conditions such as electric mining trucks.

[0054] The laser inclinometer employs a non-contact measurement method, utilizing the properties of laser light to measure the tilt angle. It offers advantages such as high precision and long-distance measurement. If the switchgear is installed on a large electric mining vehicle and the laser inclinometer is positioned relatively high or far from the workers, it can effectively leverage its long-distance measurement capabilities to accurately determine the tilt angle of the cabinet.

[0055] In practical applications, appropriate angle detection components can be selected based on the specific testing environment. Gravity sensors and gyroscopes are less affected by the environment and are suitable for use in switchgear with lower environmental requirements. In scenarios where electric mining trucks operate outdoors and require extremely high precision, laser inclinometers and high-precision tilt sensors can provide more accurate measurement results. The availability of various types of angle detection components allows switchgear to better adapt to the complex and ever-changing working environment of electric mining trucks and to meet different testing needs such as precision and dynamic performance.

[0056] It is understood that the instruments that can be used for angle detection are not limited to those listed in this embodiment, and this embodiment does not make a unique limitation.

[0057] Furthermore, the cabinet 10 includes a mounting shell 11, a first door panel 12, and a first side panel 13. The mounting shell 11 contains an installation space 111 and a first opening 1121. The first door panel 12 covers the first opening 1121 and can rotate relative to the mounting shell 11 to a position away from the first opening 1121. Workers can easily open and close the first door panel 12, facilitating the installation of various electrical equipment and the debugging and maintenance of the electrical equipment within the installation space 111. The first door panel 12 not only provides physical protection for the electrical equipment within the installation space 111 but also prevents interference and damage from the external environment, effectively reducing the impact of external factors such as dust and moisture on the electrical equipment within the installation space 111. Specifically, the first door panel 12 can be hinged to the mounting shell 11, and the first door panel 12 can rotate relative to the first opening 1121 to cover or avoid the first opening 1121. The first side panel 13 is installed within the installation space 111 and located on the side of the installation space 111 closest to the first door panel 12. The controller 21 is installed on the first side panel 13, and the mounting plate 221 is installed at the bottom of the installation space 111 and located on the side of the first side panel 13 opposite to the first door panel 12. This arrangement positions the controller 21 relatively close to the first door panel 12, facilitating quick location and operation of the controller 21 after opening the first door panel 12. The mounting plate 221 is installed at the bottom of the installation space 111, allowing the controller 21 and the angle detection element to be arranged in layers and making full use of the depth space within the installation space 111. Simultaneously, the angle detection element and the controller 21 are respectively located on opposite sides of the first side panel 13, effectively preventing mutual interference between them. Furthermore, this arrangement improves the compactness of the electrical equipment within the cabinet 10, further optimizing the spatial layout of the electrical equipment within the cabinet 10, which is beneficial for improving the integration of the switch cabinet and effectively ensuring that all electrical equipment within the switch can be installed compactly and orderly within the installation space 111.

[0058] Feedback component 23 includes indicator light 231, which is embedded in the first door panel 12 and extends at least partially to the outer side of the first door panel 12 away from the installation space 111. When the switch cabinet experiences abnormal conditions such as tilting, indicator light 231 illuminates. Because indicator light 231 is located on the outer side of the first door panel 12, personnel can clearly see its status from outside the switch cabinet, providing a direct reminder of the tilt. Embedding indicator light 231 in the first door panel 12 also makes fuller use of the installation space 111, reducing the space occupied by indicator light 231 within the installation space 111, further improving the compactness of the electrical equipment within the switch cabinet and the overall space utilization rate of the switch cabinet.

[0059] Alternatively, feedback component 23 may include an alarm installed in cabinet 10 and electrically connected to controller 21. When the switchgear exhibits abnormal conditions such as tilting, controller 21 can activate the alarm to sound an alarm to alert staff to the tilting status of the switchgear.

[0060] Alternatively, the feedback element 23 may include an indicator light 231 and an alarm. The indicator light 231 and the alarm are simultaneously mounted on the cabinet 10. When the switchgear exhibits abnormal conditions such as tilting, the indicator light 231 visually alerts the staff, while the alarm provides an audible warning, further ensuring that staff promptly detect any tilting of the switchgear. Understandably, the indicator light 231 and the alarm can be integrated into a single structure, further improving the space utilization of the installation space 111.

[0061] Furthermore, the switch cabinet also includes a charging assembly 30. The charging assembly 30 includes a charging component 31 and a cable component 32. Along the first direction (e.g.) Figure 1 The charging component 31 is mounted on the outer side wall of the mounting housing 11 away from the first door panel 12, in the direction indicated by the middle arrow X (specifically, the length direction of the switch cabinet). Along the second direction (e.g., Figure 1The direction indicated by the middle arrow Y (specifically, the width direction of the switchgear) is such that the wiring component 32 is installed on the outer wall of one side of the mounting housing 11 and electrically connected to the charging component 31. The charging component 30 enables the switchgear to not only possess traditional power distribution and control functions but also the ability to charge other equipment. The charging component 30 greatly expands the functional range of the switchgear, allowing it to meet the needs of more diverse application scenarios. The charging component 31 can receive external electrical energy, and the wiring component 32 can transmit external electrical energy to the battery of the electric mining car. The charging component 31 is located away from the outer wall of the first door panel 12. When the electric mining car is parked in the charging area, the charging equipment can be easily connected to the charging component 31 located on the outer wall without opening the first door panel 12. The charging component 31 and the first door panel 12 will not interfere with each other. During the charging process of the electric mining car, personnel can also open and close the first door panel 12 to perform debugging, maintenance, and other operations on the electrical equipment within the installation space 111. Meanwhile, by mounting the charging component 31 and the cable component 32 on the outer wall of the mounting housing 11, the space occupied within the mounting space 111 is avoided, allowing for a more compact arrangement of other electrical equipment within the mounting space 111 and improving the space utilization rate inside and outside the switch cabinet. The charging component 31 and the cable component 32 are mounted on different outer walls of the mounting housing 11, and their positions and quantities can be adjusted according to actual needs to adapt to different charging requirements and spatial layouts, making the configuration of the charging assembly 30 more flexible. This arrangement also maintains a certain degree of electrical isolation between the charging component 31 and the cable component 32 and the external power supply and the internal electrical equipment of the switch cabinet, reducing the risk of electrical faults and short circuits.

[0062] Furthermore, the charging component 31 includes a first mounting box 311, a slow-charging socket 312, and a fast-charging socket 313. The first mounting box 311 contains a first mounting cavity 3111. The slow-charging socket 312 is mounted on the wall of the first mounting cavity 3111 near the mounting housing 11. The fast-charging socket 313 is mounted on the wall of the first mounting cavity 3111 near the mounting housing 11 and is spaced apart from the slow-charging socket 312. Both the slow-charging socket 312 and the fast-charging socket 313 are electrically connected to the wiring component 32. The slow-charging socket 312 and the fast-charging socket 313 are modularly designed, allowing for independent installation and maintenance, thus improving the flexibility and maintainability of the charging component 31. When either the slow-charging socket 312 or the fast-charging socket 313 is damaged, the other can still charge the electric mining truck, ensuring continued charging and use of the electric mining truck and reducing downtime costs for maintenance. The first mounting box 311 is used to house the slow-charging socket 312 and the fast-charging socket 313, protecting them from damage caused by rain, sand, etc. The slow-charging socket 312 and the fast-charging socket 313 are spaced apart on the wall of the mounting shell 11, without occupying the internal mounting space 111, thus avoiding mutual interference and ensuring the stable reliability of the switch cabinet.

[0063] The first mounting box 311 is provided with a charging door panel 3112, which covers the first mounting cavity 3111. The charging door panel 3112 can be rotated to a position away from the first mounting cavity 3111. Specifically, the charging door panel 3112 can be hinged to the first mounting box 311.

[0064] Furthermore, the charging assembly 30 also includes a first conducting device 33 and a second conducting device 34. The first conducting device 33 is installed within the installation space 111 and located on the side of the first side panel 13 away from the first door panel 12 along a first direction. The first conducting device 33 is electrically connected between the slow charging socket 312 and the ribbon cable component 32, and is also electrically connected to the controller 21. The second conducting device 34 is installed within the installation space 111 and located on the side of the first side panel 13 away from the first door panel 12 along a first direction. The second conducting device 34 is electrically connected between the fast charging socket 313 and the ribbon cable component 32, and is also electrically connected to the controller 21. Both the first conducting device 33 and the second conducting device 34 are electrically connected to the controller 21, enabling the controller 21 to monitor and control the charging process in real time, optimize the charging strategy, improve charging efficiency, and effectively prevent safety hazards such as overcharging and overcurrent. The slow charging socket 312 and the fast charging socket 313 are connected to the ribbon cable component 32 through the first conducting device 33 and the second conducting device 34, respectively, realizing independent control of the two charging methods and ensuring that the charging component 30 can operate stably and safely under different charging needs.

[0065] The first conductive device 33 is installed within the installation space 111 and located on the side of the first side panel 13 away from the first door panel 12 along the first direction. This allows the first conductive device 33 to be positioned close to the side of the slow-charging socket 312 away from the mounting shell 11, reducing the length of the connection line between the slow-charging socket 312 and the first conductive device 33, thus improving the structural compactness of the installation space 111. The second conductive device 34 is located near the controller 21, which reduces the length of the connection line between the second conductive device 34 and the controller 21, further improving the structural compactness of the installation space 111 and saving more space within the installation space 111.

[0066] Furthermore, the first conducting device 33 includes a first DC contactor 331 and a first fuse 332. Along the first direction, the first DC contactor 331 is located on the inner wall of the mounting housing 11 away from the first door panel 12, and is electrically connected between the slow-charging socket 312 and the controller 21. Along the first direction, the first fuse 332 is located on the inner wall of the mounting housing 11 away from the first door panel 12 and is spaced apart from the first DC contactor 331, and is electrically connected to the first DC contactor 331. The first fuse 332 can quickly melt and disconnect the circuit in the event of a short circuit or overload, thereby preventing damage to the charging assembly 30 or even serious consequences such as fire, ensuring circuit safety during the slow-charging process. The first DC contactor 331 closes or opens the circuit under the command of the controller 21, realizing precise control of the slow-charging socket 312. This arrangement not only improves charging efficiency but also ensures the safety and reliability of the charging process.

[0067] By arranging the first DC contactor 331 and the first fuse 332 along the first direction on the inner wall of the mounting housing 11, the entire charging assembly 30 becomes more compact, saving internal space in the switch cabinet. Simultaneously, the inner wall of the mounting housing 11 helps to quickly dissipate the heat generated by the first DC contactor 331 and the first fuse 332, preventing performance degradation or malfunction due to overheating.

[0068] Furthermore, the second conducting device 34 includes a second DC contactor 341 and a second fuse 342. Along the first direction, the second DC contactor 341 is located within the mounting space 111 and close to the first conducting device 33, and is electrically connected between the fast-charging socket 313 and the controller 21. Along the first direction, the second fuse 342 is located within the mounting space 111 and between the second DC contactor 341 and the controller 21, and is electrically connected to the second DC contactor 341. The second fuse 342, as a protective element of the fast-charging circuit, can quickly melt and disconnect the circuit in the event of a short circuit or overload, preventing serious consequences such as equipment damage and fire. Simultaneously, the second DC contactor 341, under the control of the controller 21, precisely controls the on / off state of the fast-charging socket 313, providing another layer of circuit protection. Since fast charging circuits typically have high current and power, both the second fuse 342 and the second DC contactor 341 can cut off the circuit. The second conducting device 34 has a dual protection mechanism, ensuring circuit safety during fast charging and reducing the risk of failure. Furthermore, the second conducting device 34 is located closer to the sidewall of the mounting housing 11 along the second direction, allowing for heat dissipation through this sidewall. This helps reduce the operating temperature of the second conducting device 34, improving the lifespan and stability of the device.

[0069] The wiring component 32 includes a wiring box 321 and a copper busbar 322. The wiring box 321 has a second mounting cavity 3211. The copper busbar 322 is installed in the second mounting cavity 3211, with one end extending into the mounting space 111 and electrically connected to the first fuse 332 and the second fuse 342, and the other end electrically connected to the switch cabinet output line. The switch cabinet output line is connected to the battery of the electric mining car to charge the electric mining car.

[0070] Multiple protective coils 3212 are also installed inside the second mounting cavity 3211. These protective coils 3212 are spaced apart on the inner bottom wall of the cable box 321. The switchgear output lines pass through the protective coils 3212 and connect to the battery of the electric mining car. The protective coils 3212 protect the switchgear output lines. Specifically, the protective coils 3212 are pagoda-shaped, accommodating switchgear output lines of different diameters and preventing them from being scratched by the edge of the cable box 321 as they extend out of the second mounting cavity 3211. The pagoda-shaped protective coils 3212 are generally made of insulating materials such as rubber or plastic. The pagoda-shaped protective coils 3212 prevent short circuits between switchgear output lines or between the switchgear output lines and the cable box 321.

[0077] On the other hand, this application also provides an electric mining car that includes the aforementioned switchgear. Therefore, the electric mining car includes all the technical effects of the aforementioned switchgear. Since the technical effects of the switchgear have already been described in detail above, they will not be repeated here.

[0078] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0079] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0080] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
