Description

Technical Field

[0001] The present invention relates to the technical field of power grid equipment storage, and in particular to a power grid spare parts storage container and a storage method and a transportation method. Background Art

[0002] The voltage of the main grid is generally 110, 220, 500Kv, etc., and is mainly used for long-distance, large-capacity, high-voltage power transmission. The equipment of the main grid includes high-voltage transformers, reactors, lightning arresters, circuit breakers, transformers, disconnectors, power cables and related accessories. Due to the large physical size, heavy weight, and long production cycle of the main grid equipment, in order to ensure that emergency repair tasks can be carried out in time when the main grid equipment fails, spare parts of the main grid equipment are usually stored to ensure the normal operation of the power grid in a timely manner and improve the reliability and stability of the power system.

[0003] Some common characteristics of main grid equipment are: (1) The equipment consists of many parts and is often split into several separate packages during transportation and warehouse storage; (2) The voltage level of the main grid equipment is high, so this type of equipment is long and heavy; (3) Except for a small number of equipment (transformers and reactors) that need to be oiled during storage and have extremely large dimensions and heavy weight (all exceeding 100 tons), which are not suitable for indoor storage, other equipment is stored indoors to prevent wind and rain from accelerating the aging of the equipment.

[0004] At present, the storage method of domestic main network equipment spare parts indoors is to stack them flat on the bottom of the indoor warehouse. Due to the large variety of main network equipment, various packaging forms, and many main network sites, the spare parts reserve is huge. Therefore, a large amount of warehouse space is occupied, the storage capacity utilization rate is extremely low, and semi-automated / automated operation methods cannot be used, which increases the storage cost of the entire main network equipment spare parts. In addition, they cannot be stacked during transportation, resulting in high transportation costs.

[0005] Therefore, there is an urgent need to design a power grid spare parts storage container and a storage method and a transportation method to overcome the deficiencies of one or more of the above-mentioned prior arts. Summary of the invention

[0006] The technical solution adopted by the present invention to solve the above technical problems is: to provide a power grid spare parts storage container, characterized in that it includes: a frame, the top of the frame is open, each corner of the frame is provided with a main docking seat, and the main docking seat located at the bottom of the frame is detachably connected with an automatic lock.

[0007] In a preferred embodiment, the frame is provided with four containers, namely, container A with the longest length, container B with two-thirds of the length of container A, container C with half of the length of container A, and container D with one-third of the length of container A, and the widths and heights of the four containers are equal.

[0008] In a preferred embodiment, the container A, the container B and the container C are provided with secondary docking seats on opposite sides along the width direction, and the secondary docking seats are adapted to the automatic lock. The secondary docking seat of the container A is located at two-thirds, one-third and one-half of the total length of the container A, the secondary docking seat of the container B is located at one-quarter, one-half and three-quarters of the total length of the container B, and the secondary docking seat of the container C is located at one-third and two-thirds of the total length of the container C.

[0009] In a preferred embodiment, a pull rod is detachably connected between the two corresponding secondary docking seats on the container A, the container B and the container C.

[0010] On the other hand, a method for indoor three-dimensional storage of power grid spare parts is provided, comprising the power grid spare parts storage container described in any one of the above embodiments, comprising the following steps: S1, investigating and actually measuring the size of main grid equipment spare parts, and making storage containers for placing main grid equipment spare parts according to the investigation results, wherein the lengths of the containers are not equal, and the containers are divided into container A, container B, container C, and container D in descending order;

[0011] S2. Compare the main network equipment spare parts with each container, and put the largest main network equipment spare part into the smallest loadable container, and then compare the other main network equipment spare parts with the containers in descending order and put them into suitable containers until the main network equipment spare parts are loaded;

[0012] S3. According to the total number of containers used, the containers are combined and analyzed. If the total capacity is greater than the capacity of the two containers A, two containers A are used for containerization, and the remaining part is filled in the process of step S2; if the total capacity is less than the capacity of the two containers A, one container A is used for filling, and the remaining part is combined;

[0013] S4. After filling, container A is used as the bottom layer in the containers loaded with spare parts of the same series of main network equipment, and containers B, C, and D are combined and stacked on top of container A. The total length of the combination of containers B, C, and D is less than or equal to the length of container A.

[0014] In a preferred embodiment, the containers are stacked in a single row or double row or a combination of single and double rows, and a predetermined gap is left between two adjacent containers in each row.

[0015] On the other hand, a transportation method is also provided, including a power grid spare parts storage container as described in any one of the above embodiments, including the following steps: S10, determining the length of the transport vehicle and the number of transport vehicles according to the main grid equipment spare parts to be transported; S20, determining the container combination scheme of each transport vehicle according to the length of the transport vehicle; S30, lifting the container onto the transport vehicle by lifting equipment according to the combination scheme of step S20.

[0016] In a preferred embodiment, in step S20, a suitable container is selected based on the longest main network equipment spare part, and the main network equipment spare parts are placed in the container. If the container has remaining space, the remaining main network equipment spare parts that fit the remaining space are placed.

[0017] In a preferred embodiment, in step S30, the container containing the longest main network equipment spare parts is hoisted onto the transport vehicle as the bottom layer.

[0018] In a preferred embodiment, the number of layers of containers loaded on the transport vehicle is less than or equal to two layers.

At the same time, the design of the containers enables the containers to be matched in various combinations, which is convenient for stacking in storage and matching during transportation, aiming to reduce costs in various procedures, and adopts a standard design. The standard three-dimensional stacking solution lays a solid foundation for the optimization of subsequent functions. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1-Figure 3 As shown, the present invention provides a power grid spare parts storage container, characterized in that it comprises: a frame 10, the top of the frame 10 is open, each corner of the frame 10 is provided with a main docking seat 11, and the main docking seat 11 at the bottom of the frame 10 is detachably connected with an automatic lock 14;

[0034] Specifically, the frame 10 with an opening on the top is convenient for placing and removing the equipment, and improves the convenience of loading and unloading. To facilitate the connection between multiple frames 10, a main docking seat 11 is provided at each corner of the frame 10, which is convenient for connecting with the frames 10 in the upper and lower directions. In order to improve the convenience of connection between the upper and lower frames 10, an automatic lock 14 is detachably connected in the docking seat at the bottom of the frame 10. The automatic lock 14 adopts the existing mature gravity self-locking technology, so it is not elaborated here. When the upper and lower frames 10 are stacked, the automatic lock 14 can complete the locking cooperation with the docking seat in the lower frame 10 to realize the connection between the two frames 10.

[0035] Furthermore, the frame 10 is provided with four containers, namely, the container A16 with the longest length, the container B17 set at two-thirds of the length of the container A16, the container C18 set at one-half of the length of the container A16, and the container D19 set at one-third of the length of the container A16, and the width and height of the four containers are equal;

[0036] Specifically, since the frame 10 is used to place spare parts of power grid equipment, and the volumes of various components of the power grid equipment are different, in order to facilitate stacking and transportation, in the present embodiment, four frames 10 are provided, namely, container A16, container B17, container C18, and container D19; among them, container A16 has the longest length, which is adapted to the length of the largest spare parts of power grid equipment that can be placed indoors, and the width is designed because it is found in actual measurements of spare parts of power grid equipment that its maximum width does not exceed the regulations of the Ministry of Transport on the management of highways for overloaded transport vehicles. Therefore, the width of the regulations is used as a reference, and the height is determined according to the maximum height of the spare parts of power grid equipment. In actual measurements, the height of the spare parts of power grid equipment is 1.1 meters, so the height of container A16 needs to be greater than 1.1 meters so that the spare parts can be completely stored. In order to avoid being bumped, for the convenience of subsequent description, the length of container A16 is defined as L1; after the maximum length is determined, the remaining containers can be shortened step by step according to the length of container A16. In this application, in order to improve the convenience and neatness of stacking, the length of container B17 is two-thirds of L1, defined as L2, the length of container C18 is half of L1, defined as L3, and the length of container D19 is one-third of L1, positioned as L4; and the width and height of containers B17, C, and D are consistent with those of container A16. Through this design, containers A16, B, C, and D can be stacked in a variety of ways, including but not limited to L1=L2+L4, L1=L3*2, L1=L4*3, etc., to facilitate later stacking.

[0037] Furthermore, the container A16, the container B17 and the container C18 are provided with secondary docking seats 12 on opposite sides along the width direction, and the secondary docking seats 12 are adapted to the automatic lock 14. The secondary docking seat 12 of the container A16 is located at two-thirds, one-third and one-half of the total length of the container A16, the secondary docking seat 12 of the container B17 is located at one-quarter, one-half and three-quarters of the total length of the container B17, and the secondary docking seat 12 of the container C18 is located at one-third and two-thirds of the total length of the container C18;

[0038] Specifically, since containers B17, C, and D can be combined in a variety of ways to match the length of container A16, in order to facilitate the connection between the upper container and the lower container, a secondary docking seat 12 is provided at the predetermined position on the top of containers A16, B, and C. The secondary docking seat 12 is adapted to the automatic lock 14 and is used to lock with the automatic lock 14 of the upper layer. The secondary docking seat 12 of container A16 is located at two-thirds, one-third, and one-half of L1, and these three areas correspond to container B17, container D19, and container C18 respectively; the secondary docking seat 12 of container B17 is located at two-thirds, one-third, and one-half of L1 respectively. The docking seat 12 is located at one quarter, one half, and three quarters of L2, of which one half corresponds to the length of container D19, three quarters and one quarter correspond to the length of container C18 respectively, and the secondary docking seat 12 of container C18 is located at one third and two thirds of L3, corresponding to the length of container D19 respectively. In this way, three containers D19 or two containers C18 or one container B17 plus one container D19 can be connected above container A16, and so on, so that the containers between the upper and lower layers can be locked and fixed together.

[0039] Furthermore, a pull rod 15 is detachably connected between the two corresponding secondary docking seats 12 on the container A16, the container B17 and the container C18;

[0040] Specifically, since the lengths of containers A16, B, and C are relatively long, in order to enhance the firmness of the containers on both sides along the width direction, two opposite secondary docking seats 12 are detachably connected with pull rods 15, which pull the two sides of the container together to prevent the two sides of the container from tilting and deforming outwards under extrusion.

[0041] It should be pointed out that since the containers can be stacked upwards during storage, in order to improve the firmness of the containers and prevent the sides of the containers from bending downward, each container is provided with a reinforcing support column at the position where the secondary docking seat is provided, thereby further increasing the service life of the container.

[0042] On the other hand, Figure 6 As shown, an indoor three-dimensional storage method for the power grid spare parts storage container described in the above embodiment is provided, comprising the following steps: S1, investigating and actually measuring the size of the main grid equipment spare parts, and manufacturing storage containers for placing the main grid equipment spare parts according to the investigation results, wherein the lengths of the containers are not equal, and the containers are divided into container A16, container B17, container C18, and container D19 in descending order;

[0043] S2. Compare the main network equipment spare parts with each container, and put the largest main network equipment spare part into the smallest loadable container, and then compare the other main network equipment spare parts with the containers in descending order and put them into suitable containers until the main network equipment spare parts are loaded;

[0044] S3. According to the total number of containers used, the containers are combined and analyzed. If the total capacity is greater than the capacity of the two containers A16, two containers A16 are used for containerization, and the remaining part is filled in the process of step S2; if the total capacity is less than the capacity of the two containers A16, one container A16 is used for filling, and the remaining part is combined;

[0045] S4. After the filling is completed, the containers loaded with the same series of main network equipment spare parts are stacked on top of container A16 with container A16 as the bottom layer, and containers B17, C18, and D19 are stacked together. The total length of the combination of containers B17, C18, and D19 is less than or equal to the length of container A16.

[0046] Specifically, firstly, the size of the spare parts of the main network equipment, that is, the spare parts of the power grid equipment is actually measured, and the length, width and height of the container A16 are determined according to the maximum value of the measurement and the regulations of the Ministry of Transport on the management of overloaded transport vehicles on highways. The containers B17, C and D are shortened step by step. When placing, the longest spare part is placed in the smallest loadable container. If the size of the spare part is compatible with the container C18 and is larger than the size of the container D19, it is placed in the container C18. The other spare parts are placed in the corresponding containers from large to small according to the size until all the spare parts are loaded. Then, according to the total number of containers used, a combination analysis is performed. In the combination method, since the spare parts are placed in the smallest loadable container during loading, the total capacity can be obtained by adding the total number of containers. When the total capacity is greater than the total capacity of the two containers A16, two containers can be used. A16, for collection; if the total capacity is less than the total capacity of the two containers A16, one container A16 can be used for filling, and the remaining part is calculated according to the total capacity, and a suitable container is selected for containerization, which can reduce the number of containers used and the number of operations in a series of links such as warehousing and subsequent loading, thereby greatly reducing various costs, and can improve work efficiency and shorten the operation time in the warehouse; when the filling is completed, the containers loaded with the same series of spare parts are placed on top of the container A16 with the container A16 as the bottom layer, and the containers B17, C, and D are combined and placed on top of the container A16, and the upper and lower layers of the containers are locked and fixed by the automatic lock 14, wherein in order to prevent the situation where the lower layer is smaller and the upper layer is larger, the total length of each combination must be equal to or less than the length of L1; wherein due to factors such as manufacturing errors and combination errors, in order to avoid the inability to combine due to the existence of errors, gaps must be reserved between the combinations of containers.

[0047] It should be pointed out that the above combination method takes into account the existence of errors, such as L1 = L4*3+gap*2, and under this design, the stacking height is only limited by the height of the warehouse and the working height of the hoist.

[0048] When stacking, taking into account the different widths of each warehouse, the containers can be stacked in double rows, single rows, or a combination of single and double rows. To facilitate loading and lifting, an operating channel must be reserved for vehicles to pass through.

[0049] On the other hand, Figure 5 As shown, a transportation method is also provided, comprising the power grid spare parts storage container described in any one of the aforementioned embodiments, comprising the following steps: S10, determining the length of the carriage of the transport vehicle and the number of transport vehicles according to the main grid equipment spare parts to be transported; S20, determining the container combination scheme of each transport vehicle according to the carriage length of each transport vehicle; S30, hoisting the container onto the transport vehicle by hoisting equipment according to the combination scheme of step S20;

[0050] Specifically, first determine the number of transport vehicles and the length of the transport vehicle carriages according to the main network equipment and spare parts that need to be transported. For example, if the total volume of the main network equipment and spare parts that need to be transported is equal to the capacity of container A16, then select a transport vehicle that matches the length of container A16, or two transport vehicles that match the length of container C18, or one transport vehicle that matches the length of container C18, etc., wherein the determination of the carriage length also needs to consider the length of the longest main network equipment spare part that needs to be adapted; then analyze the combination scheme of the container according to the determined length of the transport vehicle carriage, if the length of the transport vehicle carriage is equal to L1, then the combination scheme includes but is not limited to L1=L2+L4, L1=L3*2, L1=L4*3, etc. Finally, according to the determined combination scheme, lift the container onto the transport vehicle by lifting tools.

[0051] Furthermore, in step S20, a suitable container is selected based on the longest main network equipment spare part as the standard, and the main network equipment spare part is placed in the container. If the container has remaining space, the remaining main network equipment spare parts that fit the remaining space are placed;

[0052] Specifically, the combination scheme of the containers also includes the matching of the container capacities. When loading the containers, the longest main network equipment spare parts are used as the standard and placed in the containers. If there is still space left in the container, other main network equipment spare parts with suitable remaining space are placed. If not, they are reloaded in other suitable containers to achieve the goal of using the least number of containers to place the most main network equipment spare parts.

[0053] Furthermore, in step S30, the container containing the longest main network equipment spare parts is hoisted onto the transport vehicle as the bottom layer;

[0054] Specifically, when loading, since the height of the containers is all 1.2 meters, even if the height is 2.4 meters after double-layer placement, it is still within the regulations of the Ministry of Transport on the management of highways for overloaded transport vehicles. Therefore, double-layer stacking is adopted when loading, so as to use the least vehicles to transport the most spare parts, thereby reducing transportation costs. When loading, the container with the longest main network equipment spare parts is preferentially hoisted onto the transport vehicle as the bottom layer. Through this solution, a combination of multiple containers can be realized, the number of transport vehicles can be reduced, and transportation costs can be saved.

[0055] In summary, the present application designs containers so that they can be stacked and stored, making full use of warehouse space and thus reducing storage costs. At the same time, the design of the containers enables containers to be combined in a variety of ways, making them convenient for stacking in storage and for transportation, aiming to reduce costs in individual procedures. The standard design and standard three-dimensional stacking solution lay a solid foundation for the optimization of subsequent functions.

[0056] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
