Water conservancy planning usually includes the assessment and analysis of water resources, and the determination of the layout and scale of water conservancy projects, such as reservoirs, dams, channels, pumping stations, etc. At the same time, various factors such as ecological environment protection, economic and social development needs, flood control and disaster reduction requirements, etc. need to be considered.
[0003] During the water conservancy planning process, it is necessary to go to the site to draw planning drawings according to the actual scene. When drawing planning drawings, it is necessary to set up a drawing board on the site for drawing.

[0027] The present application will be further described in detail below with reference to the drawings and embodiments.
[0028] Referring to Figures 1 to 4 , the embodiments of the present application provide a drawing device, including a drawing board 1. A support assembly 2 is arranged at the bottom of the drawing board 1, and a clamping assembly 3 is arranged outside the drawing board 1. The clamping assembly 3 includes a clamping iron sheet 31. Connecting blocks 32 are fixedly installed on the backs of the upper and lower sides of the clamping iron sheet 31. A moving rod 33 is fixedly installed between the two connecting blocks 32. A magnet block 34 is fixedly installed on the front of the moving rod 33. The upper and lower moving rods 33 are respectively slidably connected to the top and bottom of the drawing board 1, and the front of the magnet block 34 is slidably connected to the back of the drawing board 1. The clamping iron sheet 31 is located on the front of the drawing board 1.
[0029] A fixing block 37 is fixedly installed on the back of the drawing board 1. A screw rod 38 is rotatably connected to the top of the fixing block 37. A slider 36 is screwed on the outer side of the screw rod 38. The slider 36 is slidably connected to the back of the drawing board 1. A knob 39 is fixedly installed on the top of the screw rod 38. On the opposite sides of the two moving rods 33, moving blocks 35 are fixedly installed. Connecting rods 310 are hinged between one side of each moving block 35 and the corresponding slider 36.
[0030] In this embodiment, when fixing the drawing, the left and right sides of the drawing are respectively placed on the front of the drawing board 1 and between the two clamping iron sheets 31 and the drawing board 1. And before placing, first pull the clamping iron sheet 31 outwards to break away from the adsorption of the magnet block 34, so that the drawing can be placed under the clamping iron sheet 31. After placing, release the clamping iron sheet 31. After releasing, the clamping iron sheet 31 is adsorbed by the magnet block 34, and the drawing is fixed by the clamping force of the clamping iron sheet 31. The two sides of the drawing are fixed by the left and right clamping iron sheets 31, greatly increasing the clamping area, thus greatly improving the stability of the drawing fixation; and the clamping iron sheet 31 is relatively thin. Under the adsorption of the magnet block 34, the clamping iron sheet 31 near the middle is adsorbed on the drawing board 1, and the clamping iron sheet 31 at the edge remains bent; and before clamping, the knob 39 can be rotated to drive the screw rod 38 to rotate. The rotation of the screw rod 38 drives the slider 36 to move up and down. The up and down movement of the slider 36 in cooperation with the connecting rod 310 can drive the moving blocks 35 and the moving rods 33 on both sides to move synchronously and in opposite directions, so as to change the left and right positions of the clamping iron sheet 31 and the magnet block 34, and the purpose of clamping drawings of different sizes can be achieved through the change of the position.
[0031] Refer to Figures 1 to 4 In one aspect of this embodiment, the support assembly 2 includes a support plate 21. A support rod 25 is fixedly installed on the top of the support plate 21. An adjusting rod 26 is inserted between the two support rods 25. A bolt 27 is fixedly installed between the support rod 25 and the adjusting rod 26.
[0032] Support legs 22 are fixedly installed at the four corners of the bottom of the support plate 21. A reinforcing plate 23 is fixedly installed between the front and rear support legs 22. A storage plate 24 is fixedly installed between the two reinforcing plates 23. The drawing board 1 is located directly above the support plate 21. The support legs 22 are inclined outwards from top to bottom in sequence.
[0033] In this embodiment, when the device is installed, the support leg 22 supports the support plate 21, and the support plate 21 supports the drawing board 1. During the support, by changing the tightness of the bolt 27 being tightened, the fixed state between the adjusting rod 26 and the support rod 25 can be changed. Tightening the bolt 27 to have a certain damping between the support rod 25 and the adjusting rod 26 can ensure that the support rod 25 can rotate under external influence, and after rotation, the support stability of the upper drawing board 1 can be ensured, thereby realizing the adjustment of the angle of the drawing board 1. Items can be placed on the storage board 24.
[0034] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.
[0035] Working principle: When fixing the drawing, place the left and right sides of the drawing on the front of the drawing board 1 and between the two clamping iron sheets 31 and the drawing board 1. And before placing, first pull the clamping iron sheet 31 outwards to break away from the adsorption of the magnet block 34, so that the drawing can be placed under the clamping iron sheet 31. After placing, release the clamping iron sheet 31. After releasing, the magnet block 34 adsorbs the clamping iron sheet 31, and the drawing is fixed by the clamping force of the clamping iron sheet 31. The two left and right clamping iron sheets 31 fix the two sides of the drawing, greatly increasing the clamping area, thus greatly improving the stability of the drawing fixation; and the thickness of the clamping iron sheet 31 is relatively thin. Under the adsorption of the magnet block 34, the clamping iron sheet 31 near the middle adsorbs on the drawing board 1, and the clamping iron sheet 31 at the edge remains bent; and before clamping, the knob 39 can be rotated to drive the screw rod 38 to rotate. The rotation of the screw rod 38 drives the slider 36 to move up and down. The up and down movement of the slider 36 cooperates with the connecting rod 310 to drive the moving blocks 35 and the moving rods 33 on both sides to move synchronously and reversely, so that the left and right positions of the clamping iron sheet 31 and the magnet block 34 can be changed, and the purpose of clamping drawings of different sizes can be achieved through the change of the position; when the device is installed, the support leg 22 supports the support plate 21, and the support plate 21 supports the drawing board 1. During the support, by changing the tightness of the bolt 27 being tightened, the fixed state between the adjusting rod 26 and the support rod 25 can be changed. Tightening the bolt 27 to have a certain damping between the support rod 25 and the adjusting rod 26 can ensure that the support rod 25 can rotate under external influence, and after rotation, the support stability of the upper drawing board 1 can be ensured, thereby realizing the adjustment of the angle of the drawing board 1.
