DETAILED DESCRIPTION

[0018] Reference Figures 1 to 4 The utility model is further described in detail.

[0019] A device for urban planning surveying and mapping comprises a surveying and mapping device body 1, a base plate 2, a first support rod 3, a second support rod 4, a third support rod 5, a positioning block 6, a fixing mechanism 7, a connecting column 11, a limiter 12 and a stabilizing member 13. The top of the base plate 2 is provided with a surveying and mapping device body 1, the first support rod 3, the second support rod 4 and the third support rod 5 are annularly connected to the bottom of the base plate 2, the first support rod 3, the second support rod 4 and the third support rod 5 are hinged with a positioning block 6, the positioning block 6 is provided with a fixing mechanism 7, and the bottom of the positioning block 6 is provided with an anti-skid pattern for increasing friction, the connecting column 11 is fixed to the bottom of the base plate 2, the limiter 12 is placed on the connecting column 11, the connecting column 11 is provided with a placement hole 14, and the stabilizing member 13 is placed in the placement hole 14.

[0020] The fixing mechanism 7 includes a cap body 71, a screw rod 72, a drill bit 73 and a positioning plate 74. A positioning hole 8 is formed on the positioning block 6. The cap body 71 is rotatably connected to the positioning block 6. The screw rod 72 is fixed to the cap body 71 and placed in the positioning hole 8. A threaded hole 9 is formed on the positioning plate 74. The drill bit 73 is fixedly connected to the positioning plate 74 and a limiting hole 10 corresponding to the threaded hole 9 is formed on the drill bit 73. The screw rod 72 passes through the threaded hole 9 and extends into the limiting hole 10. The screw rod 72 is threadedly connected to the threaded hole 9.

[0021] By rotating and unfolding the first support rod 3, the second support rod 4 and the third support rod 5 respectively, and making the positioning block 6 contact the ground, the cap body 71 of the positioning block 6 on the first support rod 3, the second support rod 4 and the third support rod 5 is rotated in sequence, so that the cap body 71 drives the screw rod 72 to rotate, and the screw rod 72 drives the positioning plate 74 to move, and the positioning plate 74 drives the drill bit 73 to move until the drill bit 73 extends out of the positioning hole 8 and drills into the soil, thereby fixing the positioning block 6 on the ground, thereby enhancing the stability of the surveying and mapping equipment body 1.

[0022] The stabilizing member 13 includes a connecting wire 131, a weight ball 132, a cover body 133 and an annular plate 134. A storage hole 14 is opened at the bottom of the connecting column 11. One end of the connecting wire 131 extends into the storage hole 14 and is fixedly connected to the storage hole 14. The other end of the connecting wire 131 is fixedly connected to the weight ball 132. The weight ball 132 is placed in the storage hole 14. The annular plate 134 is fixed to the bottom of the connecting column 11 and is coaxial with the storage hole 14. The annular plate 134 is provided with threads. The cover body 133 is provided with threads. The cover body 133 is threadedly connected to the annular plate 134.

[0023] By rotating the cover body 133 until the cover body 133 is separated from the annular plate 134, the counterweight ball 132 no longer contacts the cover body 133, and then moves downward due to gravity until the connecting rope is straightened due to the gravity of the counterweight ball 132, and then the positioning blocks 6 on the first support rod 3, the second support rod 4 and the third support rod 5 contact the ground. Due to the gravity of the counterweight ball 132, the center of gravity of the base plate 2 is always facing downward, thereby further enhancing the stability of the surveying and mapping equipment body 1.

[0024] The limiting member 12 includes a fixing sleeve 121 and a U-shaped plate 122. The U-shaped plates 122 are provided with three and are annularly fixed on the fixing sleeve 121. The three U-shaped plates 122 correspond to the first support rod 3, the second support rod 4 and the third support rod 5 respectively. The fixing sleeve 121 is sleeved on the connecting column 11.

[0025] The first support rod 3 , the second support rod 4 , and the third support rod 5 are rotated until the first support rod 3 , the second support rod 4 , and the third support rod 5 are respectively engaged with the corresponding U-shaped plates 122 , thereby achieving a fixing effect.

[0026] Working principle: First, the first support rod 3, the second support rod 4 and the third support rod 5 are separated from the U-shaped plate 122 in sequence and unfolded. After the positioning block 6 contacts the ground, the cap body 71 starts to rotate, and the cap body 71 drives the screw rod 72 to rotate. The screw rod 72 is threadedly connected with the threaded hole 9 on the positioning plate 74, and then with the rotation of the screw rod 72, the positioning plate 74 is driven to move in the positioning hole 8, and then the positioning plate 74 drives the drill bit 73 to move out of the positioning hole 8 until the drill bit 73 extends into the soil, thereby fixing the positioning block 6. Fixed on the ground, the cover body 133 is rotated until the cover body 133 is separated from the connecting column 11, and then the counterweight ball 132 moves downward due to the influence of gravity, and then moves out of the storage hole 14, and then the counterweight ball 132 drives the connecting line 131 to be straightened, until the counterweight ball 132 straightens the connecting line 131, and then the counterweight ball 132 moves at the same time. Due to the gravity of the counterweight ball 132, the center of gravity of the base plate 2 is always facing downward, thereby further enhancing the stability of the surveying and mapping equipment body 1, and finally the surveying and mapping equipment is started to work.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
