Description

Technical Field

[0001] This invention relates to the field of substation secondary maintenance tool storage and carrying technology, and is applicable to the storage and use of tools in scenarios such as acceptance of new, renovated and expanded substations, protection annual calibration, new outgoing line setting values, DC and automation operation and maintenance, defect handling, and emergency repair. Specifically, it relates to a pull-rod type substation secondary maintenance toolbox. Background Technology

[0002] In the safe and stable operation of power systems, substation secondary equipment bears the important responsibility of monitoring, controlling, and protecting primary equipment, and its operating status directly affects the reliability of the entire power system. Therefore, on-site operations such as the maintenance, acceptance, and fault handling of substation secondary equipment are core aspects of power operation and maintenance work, and their efficiency and standardization level have a direct impact on the safe and economical operation of the power system. As the core carrier for storing and carrying various tools and meters during on-site operations, the toolbox's performance adaptability directly determines the smoothness of the work process and work efficiency.

[0003] In substation secondary maintenance, the standardized storage, convenient carrying, and efficient retrieval of tools and equipment directly affect the safety, timeliness, and efficiency of maintenance operations, and are a crucial foundation for ensuring the stable operation of power grid equipment. With the continuous development of power systems, the complexity of substation secondary equipment is constantly increasing, and maintenance scenarios are becoming increasingly diverse, placing higher demands on the management and use of maintenance tools. However, the traditional toolboxes widely used in current substation secondary maintenance work have gradually revealed many problems in practical application, making them unable to meet the needs of modern maintenance work and becoming a bottleneck restricting the improvement of maintenance efficiency.

[0004] The primary problem with traditional toolboxes is the disorganized storage of tools. Various tools are stored together without effective categorization or separation, making them prone to mixing during handling and relocation. This directly hinders maintenance personnel from retrieving tools, prolonging search time and frequently resulting in tools being missed or lost, severely reducing overall maintenance efficiency.

[0005] Secondly, traditional toolboxes have extremely poor adaptability to different scenarios. With only two storage layers, they cannot clearly distinguish and categorize tools for different substation secondary maintenance scenarios (such as acceptance of new, modified, or expanded equipment, and troubleshooting equipment malfunctions). Maintenance personnel must spend a significant amount of time selecting and preparing tools before carrying out different types of work, increasing the workload and increasing the risk of incomplete or mismatched tools, thus hindering the smooth progress of the maintenance work.

[0006] Meanwhile, traditional toolboxes suffer from significant shortcomings in portability and functionality. For commonly used testing equipment such as phase meters, megohmmeters, and microammeters, traditional toolboxes cannot provide integrated storage space, requiring maintenance personnel to carry them separately. This results in a fragmented and cumbersome handling process, increasing the burden on personnel. More importantly, commonly used instruments and PDAs in field operations lack convenient charging devices, and the toolboxes are not equipped with emergency lighting or temporary power supply modules. This fails to meet the emergency lighting and sudden power supply needs of the maintenance site, adversely affecting the continuity of operations.

[0007] Furthermore, the use of traditional toolboxes has led to redundant personnel deployment. Because some small instruments lack stable mounting and carrying mechanisms, dedicated personnel are required to carry them, directly increasing the personnel deployment cost and failing to meet the requirements of economy and efficiency in maintenance work. Summary of the Invention

[0008] In view of the many shortcomings of the traditional toolboxes mentioned above in terms of tool storage, scene adaptation, function supply and personnel configuration, the purpose of this application is to provide a pull-rod type substation secondary maintenance toolbox.

[0009] To achieve the objectives of this invention, the technical solution provided by this invention is as follows: A lever-type substation secondary maintenance toolbox includes an upper box, a middle box, and a lower box arranged sequentially from top to bottom. The lower part of the upper box is detachably connected to the upper part of the middle box via a connecting lock, and the lower part of the middle box is detachably connected to the upper part of the lower box via a connecting lock. The lower end of the lower box is provided with casters. A telescopic lever is installed on the back of the lower box. The upper end of the upper box is provided with a handle.

[0010] Furthermore, the upper box includes a box body and a top cover. The upper end of the box body is open, and its back side is hinged to the top cover via a hinge. The top cover can be opened and closed via the hinge.

[0011] Furthermore, a tool storage box is provided inside the box body, and the tool storage box includes multiple sub-storage boxes.

[0012] Furthermore, a removable flashlight, a milliammeter, and a power supply are embedded inside the top cover, and a USB interface and a Type-C interface are provided on one side of the top cover.

[0013] Furthermore, the upper end of the middle box has an opening, inside which a tool storage box is provided, the tool storage box including multiple sub-storage boxes.

[0014] Furthermore, the lower housing is higher than the upper and middle housings.

[0015] Furthermore, it also includes a meter holder, which includes an adjustable clamping part for holding various small meters and a locking part for detachably connecting to a telescopic rod.

[0016] Furthermore, the main body of the meter holder is made of ABS plastic.

[0017] Furthermore, the upper, middle, and lower housings are constructed with aluminum alloy frames and ABS panels.

[0018] Furthermore, it also includes a scene-specific toolbox placed in at least one of the upper, middle, and lower boxes, with multiple fixing holes at the bottom for inserting tools.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Efficiency Improvement: The tools are clearly divided into zones and are easy to access, which can shorten the time spent finding, retrieving, and storing tools during routine work / emergency repairs, thereby improving the efficiency of maintenance and emergency repairs; 2. Enhanced scenario adaptability: Through flexible assembly of different boxes, it can adapt to different scenarios such as acceptance of large-scale new construction, renovation and expansion projects and acceptance of small-scale defect handling and modification of fixed values, avoiding carrying redundancy or omissions; 3. Functional integration: The power bank integrates charging and emergency power supply, and the meter fixing device reduces the need for one person to hold the meter, thus reducing labor costs; 4. Economic and social benefits: Reduces the cost of lost and duplicate tools, shortens power outage duration, and ensures stable electricity supply for social production and daily life.
