Description

Technical Field

[0001] The present application relates to the field of distribution network planning, and in particular to a device for distribution network planning. Background Art

[0002] The distribution network refers to the power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to voltage to various users through distribution facilities. The distribution network is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. Due to the large number of components, planning the distribution network is an important prerequisite for ensuring the high-quality and efficient construction of the distribution network.

[0003] In the process of distribution network planning, distribution network planners need to conduct field measurements and draw drawings outdoors, and they need corresponding tools such as theodolites, data acquisition instruments, and various types of rulers when conducting the above two tasks (i.e. field measurements and drawing drawings). In order to adapt to the more complex outdoor working environment, planners need to carry more tools and types to ensure the accuracy of measurement and drawing.

[0004] Currently, planners place the tools they need in a box and then carry the box to the outdoor site where they are to be worked on. However, since planners carry many tools, the box is heavy, which greatly increases the labor intensity of planners. In addition, placing many tools in one box is not convenient for planners' subsequent surveying and mapping work (i.e., it is troublesome to find the corresponding tools). In addition, when planners are drawing, the drawings are light and large in weight, which makes them easily affected by the outdoor environment, resulting in situations such as curling or blowing over of the drawings, which affects the drawing quality. At this time, carrying corresponding drawing fixing tools will further increase the burden on planners.

[0005] Based on the above content, it can be seen that there is currently no device that can simultaneously meet the needs of planners to carry a large number of heavy tools, select different tools for surveying and mapping, and draw outdoors. Utility Model Content

[0040] like Figures 1 to 6 As shown, the device for distribution network planning of this embodiment includes a container box 1, a surveying and mapping unit 2, and a moving unit. The container box 1 is used to accommodate and place the tools required for surveying and mapping; the surveying and mapping unit 2 can be used as the cover of the container box 1, and can also be used as a drawing board for planners to support drawings when drawing; the moving unit can realize the movement of the container box 1 and the lifting and lowering of the surveying and mapping unit 2, so as to facilitate the surveying and mapping work of different planners in different sites. In the following, the specific structure of the above-mentioned components of the device for distribution network planning according to the utility model will be described in detail.

[0041] In this embodiment, if Figure 1 to Figure 2 As shown, the storage box 1 is formed in a rectangular parallelepiped shape, and a rectangular parallelepiped storage part 10 is formed inside the storage box. The storage part 10 of this shape is conducive to ensuring the stability of surveying and mapping tools such as tape measures when placed. However, there is no specific limitation on the size of the storage box 1 and the storage part 10, as long as all the surveying and mapping tools can be placed in the storage part 10, so as to reduce the labor intensity of planners. In addition, an opening connected to the storage part 10 is formed at the top of the storage box 1, that is, the storage part 10 is actually formed into a groove-shaped structure that opens toward the following surveying and mapping part 2, so that the surveying and mapping tools can be easily taken and placed through the opening. Furthermore, a partition 11 is also provided in the storage part 10 to separate the storage part 10 into a plurality of sub-storage parts 10, so as to realize the classification of surveying and mapping tools.

[0042] In addition, in this embodiment, a surveying and mapping part 2 is further provided on the top of the storage box 1. Specifically, a groove is provided on the bottom side of the surveying and mapping part 2 facing the opening of the storage box 1. The groove is formed into a rectangular parallelepiped shape that matches the outer contour of the storage box 1, so that the surveying and mapping part 2 can be buckled on the top of the storage box 1, that is, the surveying and mapping part 2 is formed as a cover of the storage box 1. The surveying and mapping part 2 is arranged to cover the storage box 1 through the groove, which can not only increase the airtightness of the storage part 10, but also facilitate the connection of the surveying and mapping part 2 with the lifting assembly 3 described below.

[0043] In addition, in this embodiment, if Figures 1 to 4 As shown, a fixing assembly 21 for fixing drawings is provided on the top side of the surveying and mapping part 2 away from the containing box 1. Specifically, the fixing assembly 21 includes a fixing rod 210 and a fixing plate 211, the fixing rod 210 is vertically connected to the top surface of the surveying and mapping part 2, and a limiting member 212 is provided at the other end of the fixing rod 210 away from the surveying and mapping part 2, and the shape of the limiting member 212 is not specifically limited, as long as the area of ​​the side facing the surveying and mapping part 2 is larger than the end area of ​​the fixing rod 210, so as to limit the fixing plate 211 described below. In addition, the fixing plate 211 is formed in a rectangular plate shape, and the fixing plate 211 is formed with a first through hole adapted to the fixing rod 210, through which the fixing plate 211 can be sleeved on the outside of the rod body of the fixing rod 210, and the fixing plate 211 can move along the extension direction of the fixing rod 210.

[0044] Furthermore, the fixing assembly 21 further includes a first elastic member 213, i.e., a spring in this embodiment, and the first elastic member 213 is located between the above-mentioned limit member 212 and the fixing plate 211, and the two ends of the first elastic member 213 in the extension direction are respectively connected to the limit member 212 and the fixing plate 211. It should be noted that there are no specific restrictions on the elastic coefficient and other characteristics of the first elastic member 213, but it should be satisfied that when the fixing plate 211 is fitted with the surveying and mapping unit 2, the first elastic member 213 is in a natural state or a compressed state, so that the drawings set between the fixing plate 211 and the surveying and mapping unit 2 can be pressed tightly to avoid the situation where the drawings are blown away by harsh outdoor environments such as strong winds. In this way, when the planner needs to perform a drawing operation, the fixing plate 211 is first lifted upward to compress the first elastic member 213, so that the drawings can be laid flat on the top surface of the surveying and mapping unit 2, and then the fixing plate 211 can press the drawings tightly under the elastic action of the first elastic member 213. In addition, in order to prevent the fixing plate 211 from pressing and imprinting the drawing, a rubber pad 2110 is further provided on the bottom side of the fixing plate 211 facing the surveying and mapping unit 2 .

[0045] It should be further explained that the number of the above-mentioned fixing components 21 is not fixed, as long as it can achieve the technical effect of fixing the drawings; but its position should be set at the edge of the contour of the surveying and mapping part 2 to facilitate the drawing of the drawings. In addition, a handle 20 is also provided at the edge of the top surface of the surveying and mapping part 2, so that when the planner needs to take and put the surveying and mapping tools, first remove the following connection piece 33 from the adjustment hole 311, and then lift the surveying and mapping part 2 through the handle 20 to achieve the taking and putting of the surveying and mapping tools.

[0046] In addition, in this embodiment, the moving part includes a first moving part and a second moving part, which are respectively used to realize the movement of the containing box 1 and the lifting and lowering of the surveying and mapping part 2.

[0047] Specifically, Figure 1 to Figure 2 As shown, the first movable part includes a plurality of movable wheels 5 arranged at the bottom of the storage box 1. Preferably, the movable wheels 5 are configured as universal wheels with a self-locking function, so as to better adapt to surveying and mapping sites in different environments. In addition, a horizontal plate 4 is provided on the bottom side of both ends of the above-mentioned storage box 1 in the length direction, and the bottom side of the horizontal plate 4 is flush with the bottom side of the storage box 1 to ensure the consistency and aesthetics of the overall structure of the device. Furthermore, each horizontal plate 4 is provided with a threaded hole, and a threaded rod 40 is connected to the threaded hole. A positioning plate 41 is provided at the bottom end of the threaded rod 40, that is, the end away from the surveying and mapping part 2. When planners need to draw drawings, by adjusting the positioning plate 41 to a state of being in contact with the ground, the stability of the device can be further improved, thereby improving the accuracy of drawing drawings. In addition, this embodiment Figure 1 and Figure 2 The horizontal plate 4 located on the right side of the storage box 1 is also connected to a push rod 6, which is formed into an L-shaped structure, so that it is convenient for planners to push the device to achieve the displacement of the storage box 1.

[0048] In addition, the above-mentioned moving part also includes a second moving part for driving the surveying and mapping part 2 to rise and fall. The second moving part includes two groups of lifting components 3, and the two groups of lifting components 3 are respectively connected to the two ends of the length direction of the surveying and mapping part 2 to ensure the stability of the surveying and mapping part 2 when rising and falling.

[0049] Specifically, Figure 1 to Figure 2 As shown, the lifting assembly 3 includes a fixed cylinder 30 and a lifting rod 31 connected to the fixed cylinder 30, and the extension direction of the two is parallel to the height direction of the container 1. The bottom of the fixed cylinder 30 is fixed to the top of the horizontal plate 4, and the top of the fixed cylinder 30 is formed with a fixing groove for placing the lifting rod 31. The top of the lifting rod 31 is formed with a connecting portion 310 connected to the side outer wall of the surveying and mapping unit 2, so that the lifting rod 31 is formed into a T-shaped structure. Further, as shown in FIG. Figures 5 and 6As shown, the outer wall of the top end of the fixing cylinder 30 is formed with a fixing hole 301 connected to the fixing groove, and the outer wall of the lifting rod 31 is formed with a plurality of adjustment holes 311 corresponding to the fixing hole 301, and the plurality of adjustment holes 311 are arranged along the extension direction of the lifting rod 31, so that when the following connecting assembly connects the fixing hole 301 with different adjustment holes 311, the height of the lifting rod 31 can be changed, thereby realizing the adjustment of the height of the surveying and mapping part 2, so as to adapt to the different heights of different planners.

[0050] Furthermore, the connection assembly includes a connection plate 32 and a connection member 33 of an L-shaped structure, such as Figure 1 to Figure 2 As shown, the end of the horizontal section of the connecting plate 32 is connected to the fixed cylinder 30, and the vertical section of the connecting plate 32 is formed with a connecting hole to facilitate the connection member 33 to pass through, that is, the first end of the connecting member 33 in the extension direction passes through the connecting hole and the fixing hole 301 and is inserted into the adjustment hole 311 to ensure the stability of the surveying and mapping unit 2 after the height adjustment is completed. Based on the above technical effects, the size of the connecting hole and the fixing hole 301 can be convenient for the insertion and withdrawal of the connecting member 33, and the adjustment hole 311 should be adapted to the connecting member 33 to ensure the stability of the connection. In addition, a pull ring is formed at the second end of the connecting member 33 in the extension direction to facilitate the insertion and withdrawal of the connecting member 33 by the planning personnel; in addition, a second elastic member 34 is provided on the outer side of the connecting member 33 between the pull ring and the vertical section of the connecting plate 32, and the second elastic member 34 is also formed as a spring, and the two ends of the second elastic member 34 in the extension direction are respectively connected to the pull ring and the connecting plate 32.

[0051] In this way, when the planner needs to adjust the height of the surveying and mapping part 2, the connecting piece 33 is pulled out from the adjusting hole 311 in the direction away from the containing box 1, and the second elastic piece 34 is stretched at this time; and when the height of the surveying and mapping part 2 is adjusted, the planner inserts the connecting piece 33 into the adjusting hole 311 to fix the surveying and mapping part 2. During this process, the elastic force of the second elastic piece 34 can make the insertion of the connecting piece 33 smoother, and can also reduce the possibility of the connecting piece 33 falling off from the adjusting hole 311, thereby increasing the stability of the surveying and mapping part 2.

[0052] According to the device for distribution network planning of the utility model, the planner can place the surveying and mapping tools in the containing part 10, and move the containing box 1 to the site to be surveyed through the first moving part; in addition, the drawing can be fixed on the top of the surveying and mapping part 2 through the fixing component 21 to avoid the influence of the harsh outdoor environment on the drawing, and the surveying and mapping part 2 can be moved to a position convenient for the planner to draw through the second moving part. In this way, the device can facilitate the planner to conduct field measurement and drawing outdoors, thereby improving the work efficiency of the planner.
