Description

Substation operation and maintenance equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 5, 2023, with application number 202311140231.8 and invention name “Substation Operation and Maintenance Equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of power equipment, and in particular to a substation operation and maintenance equipment. Background Art

[0003] Currently, during the construction, renovation, operation, and maintenance of power systems, the timeliness and efficiency of replacing faulty equipment within the power system are key indicators for evaluating the overall management of power grids. Domestic substations typically use traditional methods, such as cranes and maintenance personnel climbing to coordinate installation, to replace porcelain column-type equipment such as 220kV lightning arresters, CVTs, and post insulators.

[0004] However, substations usually have complex terrain and narrow spaces, and there are obstacles such as underground cables and ground electrical facilities on the ground, which can easily make it difficult for cranes to move around in the substation, resulting in poor traffic capacity and affecting work efficiency.

[0005] Summary of the Invention

[0006] Based on this, it is necessary to provide a substation operation and maintenance equipment to address the problem of poor traffic capacity and affected work efficiency due to obstruction by ground obstacles.

[0007] The present application provides a substation operation and maintenance equipment, which includes:

[0008] Mobile carrier;

[0009] An operation and maintenance execution mechanism, wherein the operation and maintenance execution mechanism is provided on the mobile carrier;

[0010] a first connector, the first connector being disposed at a head end of the mobile carrier;

[0011] a second connector, the second connector being disposed at a rear end of the mobile carrier; and

[0012] The obstacle crossing plate can be connected to or separated from the first connector, and the obstacle crossing plate can be connected to or separated from the second connector, and the obstacle crossing plate can be released and covered on an obstacle, so that the mobile carrier can pass through the obstacle crossing plate and cross the obstacle.

[0013] The substation operation and maintenance equipment described above is used in substations to assist personnel in the operation, maintenance, inspection, and replacement of porcelain column equipment such as 220kV lightning arresters, CVTs, and post insulators. During operation, the mobile carrier provides mechanical force, enabling the operation and maintenance actuator to move to the various devices to be operated, thereby completing the relevant maintenance tasks. However, when encountering obstacles such as ground cables during movement, to avoid damaging the ground cables while ensuring that the mobile carrier can pass through them smoothly, a pre-installed obstacle clearance plate at the front end of the mobile carrier is released by a first connector. The obstacle clearance plate automatically drops to the ground and covers the obstacle, allowing the mobile carrier to continue its normal movement through the obstacle clearance plate, thereby achieving the effect of crossing the ground cables without damaging the obstacles. Once the mobile carrier has completely passed the obstacle clearance plate, a second connector pre-installed at the rear end of the mobile carrier automatically connects to the obstacle clearance plate, returning the obstacle clearance plate to the mobile carrier for further use. Compared with the existing technology, the substation operation and maintenance equipment of this solution is equipped with an obstacle crossing plate, a first connector and a second connector, so it has the ability to cross obstacles and enhances the passability. It can then adapt well to the mobile construction and maintenance operations in substations with complex working conditions and terrain environments, greatly improving work efficiency.

[0038] 1 to 4 , a substation operation and maintenance equipment 100 is shown according to an embodiment of the present application, including a mobile carrier 10 , an operation and maintenance actuator 20 , a first connector 30 , a second connector 40 , and an obstacle crossing plate 50 .

[0039] The operation and maintenance execution mechanism 20 is arranged on the mobile carrier 10; the first connector 30 is arranged at the head end of the mobile carrier 10; the second connector 40 is arranged at the tail end of the mobile carrier 10; the obstacle crossing plate 50 can be connected to or separated from the first connector 30, and the obstacle crossing plate 50 can be connected to or separated from the second connector 40, and the obstacle crossing plate 50 can be released and covered on the obstacle, so that the mobile carrier 10 can pass through the obstacle crossing plate 50 and cross the obstacle.

[0040] In summary, the implementation of 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 to the substation to assist the staff in operating, repairing, replacing and other operations on the 220kV lightning arrester, CVT (Capacitor Voltage Transformer), pillar insulators and other porcelain column equipment in the station. During operation, the mobile carrier 10 provides motor force, so that the operation and maintenance actuator 20 can move to each equipment to be worked on, and then complete the relevant maintenance operations. However, when encountering obstacles such as ground cables on the ground during the movement, in order to avoid damaging the ground cables while ensuring that the mobile carrier 10 can pass through the ground cables smoothly, the obstacle crossing plate 50 pre-installed at the head end of the mobile carrier 10 is released by the first connector 30, and the obstacle crossing plate 50 falls to the ground by itself and covers the obstacles such as ground cables. 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 cables but at the same time avoiding damaging obstacles such as ground cables. After the mobile carrier 10 completely passes through the obstacle crossing plate 50, the second connector 40 pre-installed at the tail end of the mobile carrier 10 can automatically connect to the obstacle crossing plate 50, so that the obstacle crossing plate 50 returns to the mobile carrier 10 for convenient secondary use.

[0041] Compared with the existing technology, the substation operation and maintenance equipment 100 of this solution is equipped with an obstacle crossing plate 50, a first connector 30 and a second connector 40, so that it has the ability to cross obstacles and enhances the passability, and can thus adapt well to the mobile construction and maintenance operations in the substation with complex working conditions and terrain environments, greatly improving work efficiency.

[0042] It can be understood that when the obstacle board 50 is connected to the first connector 30, the head end of the mobile carrier 10 is the front end of the traveling vehicle, and the tail end is the rear end of the vehicle; when the obstacle board 50 is connected to the second connector 40, the tail end of the mobile carrier 10 becomes the front end of the traveling vehicle, and the corresponding head end is the rear end of the vehicle.

[0043] Specifically, based on the above embodiment, the first connector 30 is configured as a first hydraulic hook, two of which are arranged side by side at intervals along the width of the leading end of the mobile carrier 10. The obstacle crossing plate 50 includes a connecting surface 51 with two lifting rings 52 protruding therefrom. The first hydraulic hook can be connected or released in a one-to-one correspondence with the lifting rings 52. Similarly, the second connector 40 is configured as a second hydraulic hook, two of which are arranged side by side at intervals along the width of the trailing end of the mobile carrier 10. The second hydraulic hook can be connected or released in a one-to-one correspondence with the lifting rings 52.

[0044] The working principle of the first hydraulic hook and the second hydraulic hook is simple. Through the hydraulic driving force, they can automatically hook and connect the obstacle board 50 or release the obstacle board 50, realize the automatic release of the obstacle board 50 and cover the obstacle, facilitate the mobile carrier 10 to pass the obstacle, and realize the automatic recovery of the obstacle board 50.

[0045] The width direction of the mobile carrier 10 corresponds to the length direction of the obstacle board 50 , so two first hydraulic hooks or two second hydraulic hooks are connected to the two lifting rings 52 in a one-to-one correspondence, so that the obstacle board 50 is evenly stressed on both sides, thereby improving the installation stability of the obstacle board 50 .

[0046] Of course, it should be noted that in other embodiments, the connection structure between the above-mentioned hooks (i.e., the first hydraulic hook and the second hydraulic hook) and the lifting ring 52 can also be replaced by magnetic buckles, mechanical locks, snap buckles and other connection structures, which are also within the scope of protection of this application and will not be elaborated here.

[0047] Furthermore, based on the above embodiments, the substation operation and maintenance equipment 100 also includes a magnetic body, which is arranged on the first hydraulic hook and the second hydraulic hook and can be magnetically matched with the lifting ring 52, or the magnetic body is arranged on the lifting ring 52 and can be magnetically matched with the first hydraulic hook and the second hydraulic hook.

[0048] For example, if the magnetic material is a magnet, due to the accuracy of the moving path of the mobile carrier 10 and the shaking of the obstacle board 50 due to vibration in actual operation, there will be a lateral deviation between the landing point of the obstacle board 50 on the ground and the positions of the first hydraulic hook and the second hydraulic hook on the mobile carrier 10, which can easily prevent the first hydraulic hook and the second hydraulic hook from docking smoothly and retrieving the obstacle board 50. To address this problem, the present embodiment adds a magnet that can exert a magnetic attraction. Therefore, even if there is a certain size of position deviation spacing, the magnetic attraction can smoothly attract and contact the ring 52 with the first hydraulic hook or the second hydraulic hook, thereby ensuring that the first hydraulic hook or the second hydraulic hook is reliably connected to the ring 52 and effectively recovering the obstacle board 50.

[0049] Please continue to refer to Figure 4. In addition, 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 plate body 53 in the width direction, and the first support plate 54 and the plate body 53 are bent. One side of the second support plate 55 is connected to the other side of the plate body 53 in the width direction, and the second support plate 55 and the plate body 53 are bent. 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 accommodating groove 56 that can accommodate obstacles.

[0050] When the obstacle board 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 support the ground at the same time away from the side of the board body 53, so that the obstacle board 50 is placed firmly on the ground as a whole. At this time, the accommodating groove 56 is set towards the ground, so it can just accommodate obstacles such as ground cables, ground electrical equipment, etc. on the ground, and at the same time ensure that there is a sufficient safety distance between the groove wall of the accommodating groove 56 and the obstacle, so that the mobile carrier 10 is supported by the obstacle board 50 when passing over it to protect the obstacle from being crushed.

[0051] Based on the above embodiment, the mobile carrier 10 includes a mobile chassis 11, the front end of the mobile chassis 11 is provided with a first arc-shaped push portion 111 curved toward the ground, and the rear end of the mobile chassis 11 is provided with a second arc-shaped push portion 112 curved toward the ground.

[0052] When the obstacle crossing plate 50 is connected to the first connector 30 or the second connector 40, the obstacle crossing plate 50 is in a supine position so that the accommodating groove 56 is facing upward; when the first connector 30 or the second connector 40 releases the obstacle crossing plate 50 and moves along with the mobile carrier 10, the first arc-shaped pushing portion 111 or the second arc-shaped pushing portion 112 can push the obstacle crossing plate 50 to flip so that the accommodating groove 56 is turned to face downward to cover the top of the obstacle.

[0053] That is, taking the first connector 30 as an example, in actual operation, the first connector 30 releases the obstacle board 50 synchronously with the movement of the mobile carrier 10. When the first connector 30 releases the obstacle board 50, the continuously moving mobile carrier 10 drives the first curved push portion 111 to contact and slide from bottom to top on the connection surface 51 of the obstacle board 50, thereby exerting a pushing force on the obstacle board 50, forcing the obstacle board 50 to flip. This causes the accommodating groove 56, which was originally arranged upward when connected to the first connector 30, to gradually flip downward. Ultimately, the obstacle board 50 falls to the ground, and the obstacle is covered within the accommodating groove 56. The first connector 30, the obstacle board 50, and the mobile carrier 10 achieve perfect linkage and coordination, ultimately achieving the obstacle board 50's posture to change within space without human intervention, ensuring that the obstacle board 50 effectively covers and protects ground obstacles.

[0054] Please continue to refer to Figure 3. In some other embodiments, the mobile carrier 10 also 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 width direction of the mobile chassis 11. The first mobile track 12 and the second mobile track are located at the head and tail ends of the mobile carrier 10 and are respectively provided with upward inclined inclined portions 121.

[0055] The upwardly inclined slope 121 is equivalent to forming an avoidance space between the ground, which can reduce or avoid the collision and interference between the first movable track 12 and the second movable track and the obstacle board 50 on the ground when passing, thereby enhancing the obstacle crossing capability of the substation operation and maintenance equipment 100.

[0056] Please continue to refer to Figures 1 and 2. In addition, based on any of the above embodiments, the operation and maintenance execution mechanism 20 includes a telescopic boom 60, a mechanical claw 70 and a porcelain bottle box 80. The telescopic boom 60 is arranged on the mobile carrier 10, the mechanical claw 70 is connected to the end of the telescopic boom 60, and the porcelain bottle box 80 is arranged on the mobile carrier 10.

[0057] During operation and maintenance, the telescopic boom 60 telescopically moves to drive the mechanical claw 70 to the equipment that needs to be replaced. After grabbing the porcelain bottle, it returns to the top of the porcelain bottle box 80 through the telescopic boom 60, and finally releases the porcelain bottle into the porcelain bottle box 80. Then, it grabs the new porcelain bottle and returns to the equipment that needs to be replaced for safe installation, thereby completing the porcelain bottle replacement operation.

[0058] Furthermore, the operation and maintenance actuator 20 includes a steering drive module 90, which is mounted on the mobile carrier 10 and connected to the telescopic boom 60. Driven by the steering drive module 90, the telescopic boom 60 can rotate relative to the mobile carrier 10. The steering drive module 90 enables the telescopic boom 60 to rotate in situ, thereby flexibly adjusting the position of the mechanical claw 70 to meet the operation and maintenance needs of equipment at different locations around the mobile carrier 10 without moving the mobile carrier 10.

[0059] For example, the steering drive module 90 can be in the form of a motor and a rotating shaft, that is, the motor is connected to the telescopic boom 60 through the rotating shaft; it can also be in the form of a motor, a gear seat, and a gear ring, that is, the motor is connected to the gear seat, the gear ring is installed on the telescopic boom 60, and the gear ring is meshed with the gear seat; and so on.

[0060] In order to ensure the safety and reliability of the substation operation and maintenance equipment 100, in some embodiments, the operation and maintenance actuator 20 also includes a plurality of movable legs 90a, which are movably mounted on the mobile carrier 10 and can cooperate with the ground support.

[0061] When not in operation, the movable legs 90a are retracted onto the mobile carrier 10, reducing the lateral dimensions of the substation operation and maintenance equipment 100 and improving its maneuverability in narrow spaces. When in operation, the movable legs 90a are deployed and supported on the ground, providing lateral support for the mobile carrier 10. This helps improve the stability of the substation operation and maintenance equipment 100 and prevents it from tipping over due to an unstable center of gravity caused by lifting heavy objects.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0063] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
