[0003] Because some existing node devices are detected by gravity sensor to detect the inclination degree of node embedding, such as I-NODAL V2, Quantum etc., gravity sensor can calculate the attitude and motion state of object by measuring the displacement or acceleration of mass block under the action of gravity, but early node devices, such as I-NODAL V1, SmartSolo, cannot implant gravity sensor to detect node embedding inclination due to compact internal structure, cannot provide an accurate embedding angle measurement standard for early node devices, leading to large manual error, and the existing device without gravity sensor can only rely on visual judgment of construction workers when embedding to judge whether it is perpendicular to embedding in soil, and there is no accurate measurement standard for inclination degree, and manual error is large.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 As shown, this utility model provides a nodal seismograph horizontal state detection device, including a nodal geophone device 1. A horizontality detection mechanism 2 is provided at the top center of the nodal geophone device 1. Three positioning support rods 3 are arranged in a ring array on the outer wall of the nodal geophone device 1. A conical fixing rod 4 is fixedly installed at the bottom center of the nodal geophone device 1. The horizontality detection mechanism 2 includes a transparent detection cover 21, which is fixedly adhered to the top of the nodal geophone device 1. A dot mark 22 is fixedly painted at the top center of the transparent detection cover 21. A detection liquid 23 is provided in the inner cavity of the transparent detection cover 21, and the detection liquid 23 contains moving air bubbles.

[0020] In this embodiment, the positioning support rod 3 is connected to the outer wall of the node detector device 1 by flipping at 0 degrees and 90 degrees. When the positioning support rod 3 is at 0 degrees, it is vertically downward and in close contact with the outer wall of the node detector device 1. When the positioning support rod 3 is at 90 degrees, it is horizontal and perpendicular to the outer wall of the node detector device 1. Furthermore, the front end of the positioning support rod is provided with a threaded rod whose length can be adjusted by rotating the thread.

[0021] In summary, when embedding the node geophone device 1, the tapered fixing rod 4 can be inserted into the soil, and then the position of the air bubble contained in the detection liquid 23 in the inner cavity of the transparent detection cover 21 on the top of the node geophone device 1 is observed, so that the levelness of the node geophone device 1 can be more accurately judged; when the dot mark 22 on the top of the transparent detection cover 21 coincides with the small air bubble contained in the detection liquid 23 in the inner cavity of the transparent detection cover 21, it is proved that the node geophone device 1 is currently perpendicular to the ground and has no large inclination; if the dot mark 22 on the top of the transparent detection cover 21 has a certain deviation from the small air bubble contained in the detection liquid 23 in the inner cavity, it is proved that the embedding angle of the node geophone device 1 has a certain inclination and is not perpendicular to the ground.

[0022] Meanwhile, when embedding the node geophone device 1, the three positioning support rods can be opened and then embedded, and the three positioning support rods are horizontally attached to the ground after embedding, so that the further detection of whether the geophone is vertically embedded in the ground and the supporting and stabilizing effect can be achieved. Meanwhile, by adjusting the length of the threaded rod, the stability of the whole positioning support rod can be further improved.

[0023] The above has made a detailed description of the present application in general, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art.
