Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a substation operation and maintenance equipment. Background Technology

[0002] Currently, in the construction, renovation, operation, and maintenance of power systems, the timeliness and efficiency of replacing faulty equipment within the power system are important indicators for evaluating the overall management level of the power grid. In China, when replacing porcelain-column equipment such as 220kV surge arresters, CVTs, and post insulators in substations, the traditional method of using cranes for hoisting and maintenance personnel working at heights is commonly employed.

[0003] However, substations are usually characterized by complex terrain, limited space, and obstacles such as underground cables and electrical facilities, which can make it difficult for cranes to move within the substation, resulting in poor mobility and reduced work efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a substation operation and maintenance equipment to address the problem of poor traffic capacity and reduced work efficiency caused by ground obstacles.

[0005] This application provides a substation operation and maintenance equipment, which includes:

[0006] Mobile carrier;

[0007] An operation and maintenance execution mechanism is mounted on the mobile carrier;

[0008] A first connector is disposed at the head end of the mobile carrier;

[0009] A second connector, wherein the second connector is disposed at the tail end of the mobile carrier; and,

[0010] A barrier-crossing plate, which can be connected or detached from the first connector and the second connector, and which can be released and covered over an obstacle so that the mobile carrier can pass over the obstacle by passing over the barrier-crossing plate.

[0011] The substation operation and maintenance equipment described above is used in substations to assist workers in performing operations, repairs, and replacements of porcelain-column equipment such as 220kV surge arresters, CVTs, and post insulators. During operation, a mobile carrier provides the mobility to move the maintenance execution mechanism to various equipment locations to complete the necessary maintenance tasks. However, when encountering obstacles such as ground-laid cables, to avoid damaging the cables while ensuring the mobile carrier can pass smoothly, a barrier-crossing plate pre-installed at the front of the mobile carrier is released by the first connector. The barrier-crossing plate falls to the ground and covers the obstacles, allowing the mobile carrier to continue its normal movement. This achieves the effect of crossing the cables without damaging them. After the mobile carrier has completely passed the barrier-crossing plate, a second connector pre-installed at the rear of the mobile carrier automatically reconnects the barrier-crossing plate, allowing it to return to the mobile carrier for reuse. Compared with existing technologies, the substation operation and maintenance equipment in this solution is equipped with obstacle-crossing plates, a first connector, and a second connector, thereby enabling obstacle-crossing capabilities, enhancing its mobility, and thus enabling it to adapt well to mobile construction and maintenance operations within substations in complex working conditions and terrain environments, greatly improving work efficiency.

[0012] The technical solution of this application will be further described below:

[0013] In one embodiment, the first connector is configured as a first hydraulic hook, and there are two first hydraulic hooks arranged side by side at intervals in the width direction of the front end of the mobile carrier. The obstacle-crossing plate includes a connecting surface, and two lifting rings are protruding on the connecting surface.

[0015] In one embodiment, the substation operation and maintenance equipment further includes a magnetic body, which is disposed on the first hydraulic hook and the second hydraulic hook and can magnetically engage with the lifting ring, or the magnetic body is disposed on the lifting ring and can magnetically engage with the first hydraulic hook and the second hydraulic hook.

[0016] In one embodiment, the obstacle-crossing plate includes a plate body, a first support plate, and a second support plate. One side of the first support plate is connected to one side of the plate body in the width direction, and the first support plate is bent to the plate body. One side of the second support plate is connected to the other side of the plate body in the width direction, and the second support plate is bent to the plate body. The first support plate and the second support plate are bent toward the same side of the plate body, such that the first support plate, the plate body, and the second support plate cooperate to form a receiving groove that can accommodate obstacles.

[0017] In one embodiment, the mobile carrier includes a mobile chassis, the front end of which is provided with a first arc-shaped pushing part that bends toward the ground, and the rear end of which is provided with a second arc-shaped pushing part that bends toward the ground.

[0018] When the obstacle-crossing plate is connected to the first connector or the second connector, the obstacle-crossing plate is in a supine position with the receiving slot facing upwards; when the first connector or the second connector releases the obstacle-crossing plate and travels with the moving carrier, the first arc-shaped pushing part or the second arc-shaped pushing part can push the obstacle-crossing plate to flip so that the receiving slot turns downwards to cover the top of the obstacle.

[0019] In one embodiment, the mobile carrier further includes a first mobile track and a second mobile track, which are respectively installed on opposite sides of the mobile chassis in the width direction. The first mobile track and the second mobile track are respectively provided with upwardly inclined slopes at the front and rear ends of the mobile carrier.

The telescopic boom is mounted on the mobile carrier, the mechanical gripper is connected to the end of the telescopic boom, and the ceramic insulator box is mounted on the mobile carrier.

[0021] In one embodiment, the maintenance execution mechanism further includes a steering drive module, which is disposed on the mobile carrier and connected to the telescopic boom, and the telescopic boom can rotate relative to the mobile carrier under the drive of the steering drive module.

[0022] In one embodiment, the maintenance execution mechanism further includes multiple movable outriggers, which are movably mounted on the mobile carrier and can cooperate with ground support. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and 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, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figures 1 to 4 The present application illustrates a substation operation and maintenance equipment 100, which includes a mobile carrier 10, an operation and maintenance execution mechanism 20, a first connector 30, a second connector 40, and a barrier-crossing plate 50.

[0038] The operation and maintenance execution mechanism 20 is mounted on the mobile carrier 10; the first connector 30 is mounted at the front end of the mobile carrier 10; the second connector 40 is mounted at the rear end of the mobile carrier 10; the barrier-crossing plate 50 can be connected or separated from the first connector 30, and the barrier-crossing plate 50 can be connected or separated from the second connector 40; the barrier-crossing plate 50 can be released and covered on the obstacle, so that the mobile carrier 10 can pass over the obstacle by passing the barrier-crossing plate 50.

[0039] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: The substation operation and maintenance equipment 100 of the above solution is applied in the substation to assist the staff in performing operation, maintenance, repair and replacement of porcelain column equipment such as 220kV surge arresters, CVT (Capacitor Voltage Transformer), and post insulators in the substation. During operation, the mobile carrier 10 provides the mobility, enabling the operation and maintenance execution mechanism 20 to move to each piece of equipment to be worked on, thereby completing the relevant maintenance work. However, when encountering obstacles such as ground-laid cables during the journey, in order to avoid damaging the ground-laid cables and ensure that the mobile carrier 10 can pass through them smoothly, the obstacle-crossing plate 50 pre-installed at the front end of the mobile carrier 10 is released by the first connector 30. The obstacle-crossing plate 50 falls to the ground and covers the ground-laid cables and other obstacles. At this time, the mobile carrier 10 can continue to move normally through the obstacle-crossing plate 50, thereby achieving the effect of crossing the ground-laid cables while avoiding damaging them. After the mobile carrier 10 has completely passed through the obstacle-crossing plate 50, the second connector 40 pre-installed at the rear end of the mobile carrier 10 can automatically connect the obstacle-crossing plate 50 so that the obstacle-crossing plate 50 returns to the mobile carrier 10 for easy reuse.

[0040] Compared with existing technologies, the substation operation and maintenance equipment 100 in this solution is equipped with obstacle-crossing plate 50, first connector 30 and second connector 40, which enables it to cross obstacles and enhances its mobility. This allows it to adapt well to mobile construction and maintenance operations in substations with complex working conditions and terrain, greatly improving work efficiency.

[0041] Understandably, when the obstacle-crossing plate 50 is connected to the first connector 30, the front end of the mobile carrier 10 is the front end of the moving vehicle, and the rear end is the rear end of the vehicle; when the obstacle-crossing plate 50 is connected to the second connector 40, the rear end of the mobile carrier 10 becomes the front end of the moving vehicle, and the corresponding front end becomes the rear end of the vehicle.

[0042] Specifically, based on the above embodiments, the first connector 30 is configured as a first hydraulic hook, and there are two first hydraulic hooks arranged side-by-side at a distance along the width direction of the front end of the moving carrier 10. The barrier plate 50 includes a connecting surface 51, on which two lifting rings 52 are protruding. The first hydraulic hooks can be hooked and connected or released from the lifting rings 52 in a one-to-one correspondence. Similarly, the second connector 40 is configured as a second hydraulic hook, and there are two second hydraulic hooks arranged side-by-side at a distance along the width direction of the rear end of the moving carrier 10. The second hydraulic hooks can be hooked and connected or released from the lifting rings 52 in a one-to-one correspondence.

[0043] The working principle of the first and second hydraulic hooks is simple. Through hydraulic driving force, they can automatically hook and connect to the obstacle-crossing plate 50 or release the obstacle-crossing plate 50, so as to realize the automatic release of the obstacle-crossing plate 50 and cover the obstacle, which facilitates the passage of the mobile carrier 10 through the obstacle, and realizes the automatic recovery of the obstacle-crossing plate 50.

[0044] The width direction of the mobile carrier 10 corresponds to the length direction of the barrier plate 50. Therefore, two first hydraulic hooks or two second hydraulic hooks are connected to two lifting rings 52 in a one-to-one correspondence to make the force on both sides of the barrier plate 50 uniform, thereby improving the installation stability of the barrier plate 50.

[0045] Of course, it should be noted that in other embodiments, the connection structure between the hook (i.e., the first hydraulic hook and the second hydraulic hook) and the lifting ring 52 can also be replaced by a magnetic buckle, mechanical lock, snap fastener or other connection structure, which are all within the protection scope of this application and will not be elaborated here.

[0046] Furthermore, based on the above embodiments, the substation operation and maintenance equipment 100 also includes a magnetic body, which is disposed on the first hydraulic hook and the second hydraulic hook and can magnetically engage with the lifting ring 52, or the magnetic body is disposed on the lifting ring 52 and can magnetically engage with the first hydraulic hook and the second hydraulic hook.

[0047] For example, when using a magnet as the magnetic material, issues such as the accuracy of the moving path of the mobile carrier 10 and the shaking of the obstacle-crossing plate 50 due to vibration can cause a lateral deviation between the landing point of the obstacle-crossing plate 50 and the positions of the first and second hydraulic hooks on the mobile carrier 10. This can easily lead to the first and second hydraulic hooks failing to properly engage and retrieve the obstacle-crossing plate 50. To address this problem, this embodiment adds a magnet. The magnet can apply magnetic attraction, so even with a certain size of positional deviation, the magnetic attraction can ensure that the lifting ring 52 can smoothly engage with the first or second hydraulic hook, thereby ensuring a reliable connection between the first or second hydraulic hook and the lifting ring 52, and effectively retrieving the obstacle-crossing plate 50.

[0048] Please continue reading. Figure 4 Furthermore, based on any of the above embodiments, the obstacle-crossing plate 50 includes a plate body 53, a first support plate 54, and a second support plate 55. One side of the first support plate 54 is connected to one side of the width direction of the plate body 53, and the first support plate 54 is bent and disposed with the plate body 53. One side of the second support plate 55 is connected to the other side of the width direction of the plate body 53, and the second support plate 55 is bent and disposed with the plate body 53. The first support plate 54 and the second support plate 55 are bent toward the same side of the plate body 53, so that the first support plate 54, the plate body 53, and the second support plate 55 cooperate to form a receiving groove 56 that can accommodate obstacles.

[0049] When the obstacle crossing plate 50 is released by the first connector 30 or the second connector 40 and falls to the ground, the first support plate 54 and the second support plate 55 simultaneously support the ground on the side away from the plate body 53, so that the obstacle crossing plate 50 is placed stably on the ground. At this time, the receiving groove 56 is set facing the ground, so it can just accommodate obstacles such as ground cables and ground electrical equipment. At the same time, it ensures that there is a sufficient safe distance between the groove wall of the receiving groove 56 and the obstacle, so that when the moving carrier 10 travels over the obstacle crossing plate 50, the obstacle crossing plate 50 supports and protects the obstacle from being crushed.

[0050] Based on the above embodiments, the mobile carrier 10 includes a mobile chassis 11. The front end of the mobile chassis 11 is provided with a first arc-shaped pushing part 111 that bends toward the ground, and the rear end of the mobile chassis 11 is provided with a second arc-shaped pushing part 112 that bends toward the ground.

[0051] When the barrier-crossing plate 50 is connected to the first connector 30 or the second connector 40, the barrier-crossing plate 50 is in a supine position with the receiving groove 56 facing upwards; when the first connector 30 or the second connector 40 releases the barrier-crossing plate 50 and moves with the moving carrier 10, the first arc-shaped pushing part 111 or the second arc-shaped pushing part 112 can push the barrier-crossing plate 50 to flip so that the receiving groove 56 turns downwards to cover the top of the obstacle.

[0052] In other words, taking the first connector 30 as an example, in actual operation, the release of the barrier-crossing plate 50 by the first connector 30 and the movement of the mobile carrier 10 are synchronized. After the first connector 30 releases the barrier-crossing plate 50, the continuously moving mobile carrier 10 will drive the first arc-shaped pushing part 111 to contact and slide from bottom to top on the connecting surface 51 of the barrier-crossing plate 50, thereby applying a pushing force to the barrier-crossing plate 50, thus forcing the barrier-crossing plate 50 to flip over. This causes the receiving groove 56, which was originally arranged facing upwards when connected to the first connector 30, to gradually flip downwards, and finally the barrier-crossing plate 50 falls to the ground, with the obstacle covered in the receiving groove 56. The first connector 30, the barrier-crossing plate 50, and the mobile carrier 10 achieve perfect linkage and cooperation, ultimately realizing that the posture of the barrier-crossing plate 50 can change automatically in space without human intervention, ensuring that the barrier-crossing plate 50 effectively covers and protects the ground obstacle.

[0053] Please continue reading. Figure 3 In some other embodiments, the mobile carrier 10 further includes a first mobile track 12 and a second mobile track (not shown in the figure). The first mobile track 12 and the second mobile track are respectively installed on opposite sides of the mobile chassis 11 in the width direction. The first mobile track 12 and the second mobile track are respectively provided with upwardly inclined slopes 121 at the front and rear ends of the mobile carrier 10.

[0054] The upwardly inclined slope 121 can form an obstacle avoidance space with the ground, which can reduce or avoid collision interference between the first moving track 12 and the second moving track and the obstacle-crossing plate 50 on the ground when they pass, thereby enhancing the obstacle-crossing capability of the substation operation and maintenance equipment 100.

[0055] Please continue reading. Figure 1 and Figure 2 Furthermore, based on any of the above embodiments, the maintenance execution mechanism 20 includes a telescopic boom 60, a mechanical claw 70, and a ceramic insulator box 80. The telescopic boom 60 is mounted on the mobile carrier 10, the mechanical claw 70 is connected to the end of the telescopic boom 60, and the ceramic insulator box 80 is mounted on the mobile carrier 10.

[0056] During maintenance, the telescopic boom 60 extends and retracts, which drives the mechanical claw 70 to the location of the equipment to be replaced. After grabbing the porcelain insulator, the telescopic boom 60 returns to the top of the porcelain insulator box 80 and finally releases the porcelain insulator into the porcelain insulator box 80. Then, a new porcelain insulator is grabbed and returned to the location of the equipment to be replaced for safe installation, thus completing the porcelain insulator replacement operation.

[0057] Furthermore, the maintenance execution mechanism 20 also includes a steering drive module 90, which is mounted on the mobile carrier 10 and connected to the telescopic boom 60. The telescopic boom 60 can rotate relative to the mobile carrier 10 under the drive of the steering drive module 90. The steering drive module 90 provides the telescopic boom 60 with the ability to rotate in situ, thereby flexibly adjusting the orientation of the mechanical claw 70 to meet the maintenance needs of equipment in different surrounding locations without moving the mobile carrier 10.

[0058] For example, the steering drive module 90 can be a structure of a motor and a rotating shaft, where the motor is connected to the telescopic boom 60 via the rotating shaft; or it can be a structure of a motor, a gear housing, and a gear ring, where the motor is connected to the gear housing, the gear ring is mounted on the telescopic boom 60, and the gear ring meshes with the gear housing; and so on.

[0059] In order to ensure the safe and reliable operation of the substation maintenance equipment 100, in some embodiments, the maintenance execution mechanism 20 also includes multiple movable legs 90a, which are movably mounted on the mobile carrier 10 and can cooperate with the ground support.

[0060] In the non-operating state, the movable outriggers 90a are retracted onto the mobile carrier 10 to reduce the lateral dimensions of the substation maintenance equipment 100 and improve its maneuverability in confined spaces. In the operating state, the movable outriggers 90a are extended and supported on the ground, thus providing lateral auxiliary support to the mobile carrier 10, which helps improve the stability of the substation maintenance equipment 100 and prevents it from tipping over due to instability caused by hoisting heavy objects.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
