DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-5 As shown, the utility model provides a geological detection device for surveying and mapping engineering, including a triangular support frame 1, and also includes:

[0027] Drilling equipment, which is arranged on the tripod support frame 1 and is used for drilling underground;

[0028] A detection structure, which is arranged on the drilling equipment and is used to measure the humidity at a specified depth underground;

[0029] The drilling equipment includes a fixed rod 2, which is mounted on the top of the triangular support frame 1. A movable plate 3 is sleeved on the outer surface of the fixed rod 2. A driving motor 4 is mounted on the top of the movable plate 3. A threaded rod 5 is mounted on the output shaft of the driving motor 4. A drilling drill 6 is mounted on the bottom end of the threaded rod 5. A spiral cutter 7 is arranged at the conical portion of the bottom end of the drilling drill 6.

[0030] Among them, the detection structure includes a pressure rod 8, which is arranged inside the drilling bit 6 and is sleeved with the drilling bit 6. An extrusion piece 9 is installed at the bottom end of the pressure rod 8. A slot 10 is opened inside the drilling bit 6. A fixed shaft 11 is installed inside the slot 10. The outer surface of the fixed shaft 11 is sleeved with a first spring 12 and a protective ring 13. The top of the protective ring 13 is connected to a wire rope 14. A pulley 15 is installed inside the drilling bit 6. A humidity detection probe 16 is sleeved inside the drilling bit 6. An arc block 17 is installed at one end of the humidity detection probe 16. The outer surface of the humidity detection probe 16 is sleeved with a second spring 18.

[0031] After the drilling equipment controls the perforating drill bit 6 to penetrate deep into the ground, the pressure rod 8 and the perforating drill bit 6 cooperate to drive the extrusion piece 9 to move downward, so that the protective ring 13 can be pulled upward by the wire rope 14 and the humidity detection probe 16 can be released. At the same time, the extrusion piece 9 and the arc block 17 cooperate to drive the arc block 17 to move outward. At the same time, the humidity detection probe 16 and the perforating drill bit 6 cooperate to control the humidity detection probe 16 to detect the soil at a specified depth underground.

[0032] like Figure 1 , 2 As shown, the threaded rod 5 is threadedly connected to the triangular support frame 1, and the bottom end of the triangular support frame 1 is inserted into the ground.

[0033] The operation of the driving motor 4 will cause the threaded rod 5 to rotate, so that the cooperation between the threaded rod 5 and the triangular support frame 1 can drive the drilling drill 6 to descend, so that the ground can be drilled through the spiral cutter 7, which is convenient for detecting the humidity deep underground.

[0034] like Figure 2 As shown, the pressure rod 8 is in a "T" shape, and the two ends of the top of the pressure rod 8 pass through the punching drill bit 6 and are slidably matched with the punching drill bit 6.

[0035] Through the design of the pressure rod 8, when the pressure rod 8 is pressed, the extrusion piece 9 can be driven to descend, so that the protective ring 13 can be driven to move upward through the wire rope 14. At the same time, through the cooperation between the extrusion piece 9 and the arc block 17, the humidity detection probe 16 can be driven to move outward to detect the humidity underground.

[0036] like Figure 3 , 5 As shown, the first spring 12 is elastically supported between the notch 10 and the protection ring 13 . When the first spring 12 supports the protection ring 13 , the protection ring 13 can protect the end of the humidity detection probe 16 .

[0037] Through the design of the first spring 12, the protective ring 13 has good elastic reset performance. At this time, since the first spring 12 is in a compressed state, an elastic force will be applied to the protective ring 13, so that the humidity detection probe 16 can be protected by the protective ring 13 to prevent the soil of different layers underground from contacting the humidity detection probe 16.

[0038] like Figure 3 , 5 As shown, the bottom end of the extrusion piece 9 is provided with a chamfer, and the extrusion piece 9 is in extrusion contact with the arc block 17. The arc block 17 is divided into three groups, and the three groups of arc blocks 17 form a ring when in contact.

[0039] By setting the chamfer at the bottom of the extrusion piece 9, when the extrusion piece 9 squeezes the arc block 17, the humidity detection probe 16 will be driven by the arc block 17 to move along the inner side of the drilling drill bit 6, so as to control the contact between the drilling drill bit 6 and the underground soil for humidity detection.

[0040] like Figure 5 As shown, the second spring 18 is elastically supported between the arc block 17 and the drilling drill bit 6 .

[0041] The design of the second spring 18 allows the arc block 17 to have good elastic reset performance. At this time, since the second spring 18 is in a compressed state, an elastic force is applied to the arc block 17, thereby driving the humidity detection probe 16 to retract to the inner side of the protective ring 13.

[0042] like Figure 1 , 3 As shown, the end of the steel wire rope 14 is connected to the extrusion piece 9, the steel wire rope 14 is slidably matched with the pulley 15, and the outer surface of the fixed rod 2 is provided with a scale.

[0043] The scale set on the outer surface of the fixed rod 2 makes it easy to control the depth of the hole drilled by the drilling drill 6 in the ground. At the same time, through the cooperation between the wire rope 14 and the pulley 15, when the extrusion piece 9 moves downward, the wire rope 14 can drive the protective ring 13 to move upward and release the humidity detection probe 16.

[0044] Working principle:

[0045] First, the staff can start the drive motor 4. The operation of the drive motor 4 will cause the threaded rod 5 to rotate, so that the cooperation between the threaded rod 5 and the triangular support frame 1 can drive the drilling drill 6 to descend and perform drilling operations on the ground. When the drilling drill 6 moves to a certain depth, the staff can press the pressure rod 8 to drive the extrusion piece 9 to move downward, so that the protective ring 13 can be pulled upward by the wire rope 14 and the humidity detection probe 16 can be released. At this time, through the cooperation between the extrusion piece 9 and the arc block 17, the arc block 17 can be driven to move outward and drive the humidity detection probe 16, so that the humidity detection probe 16 can be controlled to detect the soil at a specified depth underground.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
