[0007] A marking device for field survey, comprising a marking body in the shape of a square cone, the tip of the marking body being a drill bit; a through hole arranged axially and extending to the upper end face is arranged in the marking body, a fixing mechanism for preventing the marking body from tilting is arranged in the through hole; a side channel for cooperating with the fixing mechanism is arranged on the side wall of the marking body; a cone head is arranged on the upper part of the marking body, a warning tape with a reflective strip is arranged on the side wall of the cone head; a cavity corresponding to the through hole is arranged in the cone head, and a protective door for locking the cavity is arranged on the top surface of the cone head.

[0008] To further optimize the technical solution, the cone head is cylindrical.

[0009] To further optimize the technical solution, the fixing mechanism includes a lead screw vertically arranged in the through hole, a slider is provided on the lead screw, and the lead screw is provided with a rotating handle for rotating the lead screw; both sides of the slider are respectively connected to a fixing rod, and the other end of the fixing rod is located in the side channel.

[0010] To further optimize the technical solution, a plurality of grooves are arranged on the top of the lead screw, and a protrusion that cooperates with the grooves on the lead screw is arranged on the end of the handle.

[0011] To further optimize the technical solution, an anti-dismantling lock is arranged on the protective door, and the anti-dismantling lock is connected to a voice prompter arranged in the cone head.

[0012] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.

[0013] The utility model provides a marking device for field survey, which plays a warning role by setting a warning tape and a voice prompter, and is also convenient for surveyors to find the marking body; the marking body is effectively fixed by setting a fixing mechanism, and the square pyramid marking body structure is more stable than the ordinary cylindrical structure; the difficulty of malicious removal of the marking is increased by setting a special turning handle used in conjunction with the fixing structure; and a protective door and an anti-dismantling lock are set for further protection. The utility model has the advantages of simple structure, high stability, anti-theft and warning of removal behavior. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A marking device for field survey, combined with Figures 1 to 2 As shown, it includes a marking body 1, a drill bit 2, a cone head 3, a warning tape 4, a voice prompter 5, and a fixing mechanism 6. The fixing mechanism 6 includes a through hole 61, a lead screw 62, a slider 63, a side channel 64, a fixing rod 65, a rotating handle 66, and a protective door 7.

[0019] The marker body 1 is in a square pyramid shape, and the tip of the marker body 1 is a drill bit 2 .

[0020] The marker body 1 is provided with a through hole 61 arranged axially and extending to the upper end surface, and the through hole 61 is located in the middle and upper part of the marker body 1. The side wall of the marker body 1 is provided with side channels 64 used in conjunction with the fixing mechanism 6, and there are two side channels 64.

[0021] A fixing mechanism 6 is arranged in the through hole 61 to prevent the marking body 1 from tilting. The fixing mechanism 6 comprises a lead screw 62 arranged vertically in the through hole 61, a slider 63 is arranged on the lead screw 62, and a handle 66 is arranged on the lead screw 62 for rotating the lead screw 62. A plurality of grooves are arranged on the top of the lead screw 62, and a protrusion is arranged at the end of the handle 66 for cooperating with the grooves on the lead screw 62. The two sides of the slider 63 are respectively connected to the fixing rod 65, and the other end of the fixing rod 65 is located in the side channel 64.

[0022] A cone head 3 is arranged on the upper part of the marking body 1, and the cone head 3 is cylindrical. A warning tape 4 with a reflective strip is arranged on the side wall of the cone head 3, and a warning message is written on the warning tape 4.

[0023] A cavity corresponding to the through hole 61 is provided in the cone head 3, and a protective door 7 for locking the cavity is provided on the top surface of the cone head 3. An anti-tampering lock is provided on the protective door 7, and the anti-tampering lock is connected to the voice prompter 5 provided in the cone head 3.

[0024] When the utility model is actually used, the marking body 1 is placed at the position to be marked, and the cone head 3 is hit with a heavy object. Under the action of the drill bit 2, the marking body 1 is driven into the ground. After the depth is appropriate, the anti-disassembly lock on the protective door 7 is opened, and the screw 62 is rotated by the turning handle 66, so that the slider 63 moves downward along the screw 62, and the fixing rod 65 is pushed out from the side channel 64. The fixing rod 65 is inserted into the soil to increase the overall stability and prevent the marking body 1 from tilting or being pulled out. If someone destroys the anti-disassembly lock on the protective door 7, the voice prompter 5 plays a voice prompt to stop it in time. When you want to remove the marking body 1, open the anti-disassembly lock on the protective door 7, use the turning handle 66 to rotate the screw 62, so that the slider 63 moves upward along the screw 62, pull the fixing rod 65 out of the soil and retract it into the through hole 61, and then pull out the marking body 1.
