Description

Technical Field

[0001] The invention belongs to the technical field of area measurement, in particular to a device for measuring the area of ​​complex terrain. Background Art

[0002] Complex terrain development refers to urban planning and construction activities carried out in areas with complex terrain and diverse landforms. These areas usually include mountainous areas, hilly areas, river valleys, coastlines and other areas with complex terrain. During the planning and construction process, it is necessary to fully consider these factors and formulate scientific and reasonable development plans to ensure the sustainability of urban construction and the protection of the ecological environment. Before planning the development of complex terrain, its area needs to be measured. At this time, an area measurement device is needed to calculate the area.

[0003] A patent with the publication number CN116518833B discloses an area measurement device for complex terrain development in urban planning, including a machine base, a frame fixedly mounted on the front of the machine base, a marking assembly fixedly mounted on the top of the frame, a main shaft movably mounted on the inner side of the bottom of the frame, and a measuring wheel fixedly sleeved on the outer side of the main shaft located on the inner side of the frame. The present invention utilizes the rotation of the measuring wheel itself and cooperates with the design of the protrusion and the contact to realize the conversion of a single rotation into a single upward movement of the movable rod, and at the same time, the automatic winding of the winding roller is realized again through the rotation of the measuring wheel, and the automatic movement of the recording paper and the single movement of the marking pen can automatically mark the marking points on the surface of the recording paper, so that after the measurement is completed, it only needs to count the marking points on the surface of the recording paper to realize the recording of the number of rotations.

[0004] There are still some problems in the actual application of the above scheme. In the process of using the above-mentioned area measuring device for complex terrain development in urban planning, different types of ground will be encountered during the ground measurement. When some ground has more stones, the measuring wheel is in direct contact with these stones on the ground, which may cause the measuring wheel to slide with the stones during the forward movement. The sliding measuring wheel will cause it to idle for a part, which will lead to inaccurate data measurement. At the same time, when the measuring wheel moves, when surveying on a ground with relatively moist soil, a large amount of clay will be attached to the circumferential surface of the measuring wheel, which makes it difficult for the measuring wheel to move, thereby reducing the measurement efficiency.

[0005] To this end, the present invention provides a complex terrain area measuring device. Summary of the invention

[0016] Preferably, a connecting column is fixedly connected to the top end of the positioning plate, and a clamping block is rotatably connected to the upper surface of the connecting column, and the cross section of the clamping block is matched with that of the positioning groove.

[0019] 3. The complex terrain area measuring device described in the present invention drives the dial plate to rotate by the fixed shaft. The two rotating plates in the first slot body opened on both sides of the dial plate will be squeezed and rotated back into the first slot body after contacting the plug block. However, each time the rotating plate hits the plug block, the soil on the surface of the plug block can be broken, thereby making the positioning of the plug block more accurate and preventing the plug block from affecting the measurement effect.

[0020] 4. The complex terrain area measuring device described in the present invention needs to be fixed when the device is stopped during measurement on an inclined slope. At this time, the card block is rotated so that it is no longer positioned with the positioning guide rail, and then the positioning plate is slid along the positioning groove. The cone column at the bottom of the positioning plate is then inserted into the ground, so that the measuring device can be fixed, thereby achieving the effect of protecting the equipment. At the same time, when the positioning plate is not needed, the positioning plate can be detached from the positioning guide rail by sliding it upwards, and then the rotating cover is opened and the two positioning plates are placed in the storage box, thereby achieving the effect of protecting the positioning plate.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Embodiment 1: Figures 1 to 8As shown, a complex terrain area measuring device described in an embodiment of the present invention includes a fixed box 1, a support frame 4 is fixedly connected to one side of the fixed box 1, a rotating shaft 41 is rotatably connected to the lower surface of the support frame 4, a rotating wheel 42 is fixedly connected to the circumferential surface of the rotating shaft 41, and the rotating wheel 42 is a measuring wheel, a push handle 13 is fixedly connected to one side of the fixed box 1, a plurality of plug blocks 43 are fixedly connected to the circumferential surface of the rotating wheel 42, and the plurality of plug blocks 43 are distributed in a circular array; a fixed tube 415 is fixedly connected to the bottom end of each plug block 43, a plurality of positioning tubes 417 corresponding to the number of the plug blocks 43 are fixedly connected to the circumferential surface of the rotating wheel 42, a compression spring 416 is fixedly connected to the interior of the positioning tube 417, and the end of the compression spring 416 away from the positioning tube 417 is fixedly connected to the top wall of the fixed tube 415.

[0025] Specifically, in the process of using the above-mentioned area measurement device for complex terrain development in urban planning, different types of ground may be encountered during the ground measurement process. When some ground has a large number of stones, the measuring wheel is in direct contact with the stones on the ground, which may cause the measuring wheel to slide with the stones during the forward movement. The sliding measuring wheel will cause it to idle for a part, which will lead to inaccurate data measurement. At the same time, when the measuring wheel moves and the ground is relatively wet, a large amount of clay will be attached to the circumferential surface of the measuring wheel, which will make it difficult for the measuring wheel to move, thereby reducing the measurement efficiency. Therefore, the present invention solves this problem by setting a corresponding structure. First, the staff pushes the area measuring device to the place where the measurement is required, and then starts to push the push handle 13 to push the measuring device to the position where the measurement is required, and pushes it around the edge of the measurement range. During the pushing process, the plug block 43 on the circumferential surface of the rotating wheel 42 is affected by its own gravity when encountering a stone, which causes the compression spring 416 in the fixed tube 415 to be squeezed and then compressed. At the same time, the plug block 43 is in an arc shape, so that it can slide forward along the surface of the stone. While sliding, it squeezes the stone to move to a position opposite to the forward direction, thereby achieving the effect of pushing the stone away. In addition, when encountering muddy soil for measurement, the plug block 43 can be partially inserted into the soil, thereby preventing the rotating wheel 42 from slipping on the muddy ground. The problem that different types of ground may be encountered during ground measurement and that when some ground has more stones, the measuring wheel may slide against the stones during the forward movement because the measuring wheel is in direct contact with the stones. The sliding measuring wheel may cause part of it to idle, which may lead to inaccurate data measurement. At the same time, when the measuring wheel moves and surveying is carried out on a ground with relatively moist soil, a large amount of clay may adhere to the circumferential surface of the measuring wheel, making it difficult for the measuring wheel to move, thereby reducing the measurement efficiency.

[0026] like Figure 3 As shown, in this embodiment, both ends of the rotating shaft 41 are drivingly connected to the same fixed shaft 47 , and a plurality of shifting plates 49 are fixedly connected to the circumferential surface of the fixed shaft 47 .

[0027] Specifically, in the process of the rotating wheel 42 driving the rotating shaft 41 to rotate, the rotating shaft 41 will drive the fixed shaft 47 connected thereto to rotate, and the rotation of the fixed shaft 47 will drive several shift plates 49 on the circumferential surface of the fixed shaft 47 to rotate, thereby preventing some grass plants from being entangled between the plug blocks 43 during the process of the rotating wheel 42 driving the plug blocks 43 to move, thereby affecting the normal operation of the device, thereby achieving the effect of improving the working efficiency of the device.

[0028] like Figure 4 As shown, in this embodiment, a plurality of shifting plates 49 and a plurality of inserting blocks 43 are interlaced with each other, and a shifting plate 49 is located between every two inserting blocks 43 .

[0029] Specifically, the rotating shaft 41 drives the fixed shaft 47 to rotate, thereby driving the paddles 49 on the circumferential surface of the fixed shaft 47 to rotate. By staggering each paddle 49 with the insert block 43, a better weed cleaning effect is achieved.

[0030] like Figure 4 As shown, in this embodiment, two first grooves 412 are provided at the top of each shift plate 49, and a limiting shaft 413 is rotatably connected in each first groove 412. Both ends of the limiting shaft 413 are fixed with torsion springs 414, and the circumferential surface of the limiting shaft 413 is rotatably connected to a rotating plate 410.

[0031] Specifically, in the process of the fixed shaft 47 driving the dial plate 49 to rotate, the two rotating plates 410 in the first groove 412 opened on both sides of the dial plate 49 will be squeezed and rotated back into the first groove 412 after contacting the plug block 43. However, each time the rotating plate 410 hits the plug block 43, the soil on the surface of the plug block 43 can be broken, thereby making the positioning of the plug block 43 more accurate and preventing the plug block 43 from affecting the measurement effect.

[0032] like Figure 4 As shown, in this embodiment, a plurality of cone blocks 411 are fixedly connected to the surface of each rotating plate 410 , and the cross section of the cone block 411 is triangular.

[0033] Specifically, by fixing a plurality of cone blocks 411 on the surface of each rotating plate 410, during the process of the paddle plate 49 hitting the paddle plate 49, by fixing a plurality of cone blocks 411 on the side of each rotating plate 410 that contacts the insert block 43, a better cleaning effect of the insert block 43 is achieved.

[0034] like Figure 4 As shown, in this embodiment, both ends of the rotating shaft 41 are fixedly connected with a first gear 44, each first gear 44 is transmission-connected with a first steel strip 45, each first gear 44 is transmission-connected with a second gear 46 via the first steel strip 45, and the support frame 4 is fixedly connected with two limit plates 48 at positions corresponding to the two second gears 46, and the two limit plates 48 are rotationally connected with the same fixed shaft 47.

[0035] Specifically, when the rotating shaft 41 drives the fixed shaft 47 to rotate, the first gear 44 is driven to rotate through the rotation of the rotating wheel 42. The rotation of the first gear 44 can drive the second gear 46 to rotate through the first strip steel 45. The two second gears 46 are fixedly connected to the two ends of the circumferential surface of the fixed shaft 47, so that the rotating shaft 41 can stably drive the cleaning roller to rotate.

[0036] Embodiment 2: Figures 2 to 8 As shown, compared with Example 1, another embodiment of the present invention is: a fixed barrel 2 is fixedly connected to the upper surface of the support frame 4, a pressure barrel is arranged on the upper surface of the fixed barrel 2, a connecting pipe 21 is fixedly connected to the circumferential surface of the fixed barrel 2, one end of the connecting pipe 21 away from the fixed barrel 2 is close to the ground, and one end of the connecting pipe 21 away from the fixed barrel 2 is fixedly connected to a fixing port 22, and the cross-section of the fixing port 22 is "S" shaped.

[0037] Specifically, a fixed barrel is fixedly connected to the top of the support frame 4, and then a pressure barrel is fixedly connected to the upper surface of the fixed barrel 2. The white marking dust in the fixed barrel 2 is sprayed out from the "S"-shaped fixed port 22 at one end of the connecting pipe 21 away from the fixed pipe 415 by the pressure in the pressure barrel, thereby achieving the effect of marking the positions passed on the ground at the same time.

[0038] like Figure 6 As shown, in this embodiment, both sides of the fixed box 1 are fixed with positioning parts, and each group of positioning parts includes positioning guide rails 3 fixed on both sides of the fixed box 1. The surface of each positioning guide rail 3 is provided with a positioning groove 31, and a positioning plate 32 is slidably connected in the positioning groove 31. The bottom end of the positioning plate 32 is fixed with a cone column 33, and the cross-section of the cone column 33 is triangular. The upper surface of the fixed box 1 is fixed with a storage box 11, and the upper surface of the storage box 11 is rotatably connected with a rotating cover 12. The top of the positioning plate 32 is fixed with a connecting column 34, and the upper surface of the connecting column 34 is rotatably connected with a block 35, and the cross-section of the block 35 is compatible with the positioning groove 31.

[0039] Specifically, when measuring on an inclined slope, the device needs to be fixed when it is stopped. At this time, the block 35 is rotated so that it is no longer positioned and engaged with the positioning guide rail 3, and then the positioning plate 32 is slid to make the positioning plate 32 slide along the positioning groove 31, and then the cone column 33 at the bottom end of the positioning plate 32 is inserted into the ground, so that the measuring device can be fixed, thereby achieving the effect of protecting the equipment. At the same time, when the positioning plate 32 is not needed, the positioning plate 32 can be detached from the positioning guide rail 3 by sliding it upward, and then the rotating cover 12 is opened, and the two positioning plates 32 are placed in the storage box 11, thereby achieving the effect of protecting the positioning plates 32.

[0040] Working principle: first, the staff pushes the area measuring device to the place where measurement is required, and then starts to push the push handle 13 to push the measuring device to the position where measurement is required, and pushes it around the edge of the measurement range. During the pushing process, the plug block 43 on the circumferential surface of the rotating wheel 42 is affected by its own gravity when encountering a stone, which will cause the compression spring 416 in the fixed tube 415 to be squeezed and then compressed. At the same time, the plug block 43 is in an arc shape, so that it can slide forward along the surface of the stone. While sliding, it will squeeze the stone to move to a position opposite to the forward direction, thereby achieving the effect of pushing the stone away, and when encountering muddy soil for measurement, the plug block 43 can be partially inserted into the soil, thereby preventing the rotating wheel 42 from slipping on the muddy ground; Then, in the process of the rotating wheel 42 driving the rotating shaft 41 to rotate, the rotating shaft 41 will drive the fixed shaft 47 connected thereto to rotate, specifically, the first gear 44 is driven to rotate by the rotation of the rotating wheel 42, and the rotation of the first gear 44 can drive the second gear 46 to rotate through the first strip steel 45, and the two second gears 46 are fixedly connected to the two ends of the circumferential surface of the fixed shaft 47, and the rotation of the fixed shaft 47 will drive a number of paddles 49 on the circumferential surface of the fixed shaft 47 to rotate, thereby preventing some grass plants from being entangled between the plug blocks 43 in the process of the rotating wheel 42 driving the plug blocks 43 to move, thereby affecting the normal operation of the device, thereby achieving the effect of improving the working efficiency of the device, and in the process of the rotating shaft 41 driving the fixed shaft 47 to rotate, thereby driving the paddles 49 on the circumferential surface of the fixed shaft 47 to rotate, each paddle 49 is arranged to be staggered with the plug blocks 43, thereby achieving a better effect of cleaning weeds; At the same time, when the fixed shaft 47 drives the dial plate 49 to rotate, the two rotating plates 410 in the first slot 412 opened on both sides of the dial plate 49 have a plurality of cone blocks 411 fixedly connected to the surface of each rotating plate 410. When in contact with the plug block 43, they will be squeezed and rotated back into the first slot 412. However, each time the rotating plate 410 hits the plug block 43, the soil on the surface of the plug block 43 can be broken, so that the positioning of the plug block 43 is more accurate, preventing the plug block 43 from affecting the measurement effect. Then, as the measuring device is continuously moving, a fixed barrel is fixed on the support frame 4, and a pressure barrel is fixed on the upper surface of the fixed barrel 2. The pressure in the pressure barrel sprays the white marking dust in the fixed barrel 2 out from the "S"-shaped fixed port 22 at one end of the connecting pipe 21 away from the fixed pipe 415, thereby achieving the effect of marking the position on the ground at the same time. Finally, when measuring on an inclined slope, the device needs to be fixed when it is stopped. At this time, the block 35 is rotated so that it is no longer positioned and engaged with the positioning guide rail 3, and then the positioning plate 32 is slid to make the positioning plate 32 slide along the positioning groove 31, and then the cone column 33 at the bottom end of the positioning plate 32 is inserted into the ground, so that the measuring device can be fixed, thereby achieving the effect of protecting the equipment. At the same time, when the positioning plate 32 is not needed, the positioning plate 32 can be detached from the positioning guide rail 3 by sliding it upward, and then the rotating cover 12 is opened, and the two positioning plates 32 are placed in the storage box 11, thereby achieving the effect of protecting the positioning plates 32. After completing the measurement and storing the positioning plates 32 in the storage box 11, the next complex terrain can be measured.
