When using the transient electromagnetic instrument, it is very easy to cause the transient electromagnetic instrument to be unable to fully extend in the tunnel, thereby affecting the measurement results.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an interactive warning device for a transient electromagnetic instrument, comprising a threaded rod, which is rotatably connected to the inner side of a support rod, and the inner side of a support seat is a hollow structure, and an anti-slip pad is fixedly installed on the bottom of the support seat, and a threaded connector is threadedly connected to the outer side of the threaded rod, and the threaded connector is fixedly installed on the left and right sides of an instrument body; a dust cover, which is rotatably connected to the outer side of the instrument body through a rotating shaft, and a first magnet is fixedly installed on the outer side of the instrument body, a second magnet is connected to the outer side of the first magnet, and the second magnet is fixedly installed on the outer side of the dust cover, the first magnet and the second magnet are a magnetic attraction structure, and the magnetic force between the first magnet and the second magnet is greater than the elastic force of the second telescopic spring.

[0008] Preferably, a display screen is fixedly installed inside the instrument body, a signal analysis module is fixedly installed inside the instrument body, a sound warning module is fixedly installed inside the instrument body, a vibration warning module is fixedly installed inside the instrument body, an information transmitting coil is fixedly installed outside the instrument body, and an information receiving coil is fixedly installed outside the instrument body.

[0009] Preferably, a first bevel gear is fixedly mounted on the outer side of the threaded rod, and a second bevel gear is meshingly connected to the outer side of the first bevel gear, a coaxial shaft is fixedly mounted on the outer side of the second bevel gear, and the coaxial shaft is rotatably connected to the inner side of the support seat; this structure can drive the meshing second bevel gear to rotate together and change the direction of rotation through the rotation of the second bevel gear.

[0010] Preferably, a rotating disk is fixedly installed on the outer side of the concentric shaft, and limiting holes are provided at equal angles on the inner side of the rotating disk, and the inner side of the limiting hole is engaged with a limiting rod; this structure can keep the rotating disk in a fixed state through the engagement of the limiting rod and the limiting hole.

[0011] Preferably, a fixing block is fixedly installed on the outer side of the support seat, and a limiting rod passes through the inner side of the fixing block, and a first telescopic spring is connected between the limiting rod and the fixing block; this structure can make the limiting rod reset itself through the elastic force of the first telescopic spring.

[0012] Preferably, a slide groove is opened inside the instrument body, and a second telescopic spring is fixedly installed inside the slide groove. The tail end of the second telescopic spring is fixedly connected to a sliding block, and the sliding block is nested inside the slide groove; this structure can make the sliding block reset itself through the elastic force of the second telescopic spring.

[0013] Preferably, a support rod is rotatably connected between the sliding block and the dust cover, and two groups of support rods are symmetrically arranged about the midpoint of the instrument body; this structure can fix the dust cover vertically at 90° on the outside of the instrument body through the support of the support rod.

[0014] Compared with the prior art, the utility model has the beneficial effect that the transient electromagnetic instrument interactive warning device is provided with:

[0015] 1. Interactive warning structure. This structure installs information transmitting coils and information receiving coils on the outside of the transient electromagnetic instrument to transmit and receive transient electromagnetic signals to the inside of the tunnel. The signal analysis module analyzes and processes these signals to obtain information such as the structure and properties of the underground medium. If the received information is abnormal, the signal analysis module will control the sound warning module and the vibration warning module to emit a buzzer and vibrate, thereby promptly reminding the operator to pay attention to safety;

[0016] 2. Height adjustment structure. When the height of the instrument body needs to be adjusted, the limit rod is manually pulled to separate the tail end of the limit rod from the limit hole inside the rotating disk. After separation, the rotating disk is in an active state. The rotating disk is manually rotated to drive the second bevel gear on the outer side of the concentric shaft to rotate. The rotation of the second bevel gear drives the first bevel gear meshing on the outer side to rotate together, thereby driving the threaded rod to rotate together. The rotation of the threaded rod drives the threaded connector connected to the outer side to move up and down. The up and down movement of the threaded connector drives the instrument body to move together to adjust the height, which is convenient for the use of the transient electromagnetic instrument.

[0017] 3. Dust-proof structure. When the transient electromagnetic instrument is not needed, the dust cover is rotated by rotating the shaft so that the dust cover is attached to the outside of the instrument body to protect the parts inside the instrument body. When the dust cover is attached to the outer surface of the instrument body, the magnetic force of the first magnet and the second magnet fixes the dust cover to the outside of the instrument body.

[0018] Furthermore, when the instrument body needs to be used, the dust cover is manually pulled to separate the first magnet and the second magnet. As the distance between the first magnet and the second magnet increases, the magnetic force of the first magnet and the second magnet decays. At this time, the elastic force of the second telescopic spring is greater than the magnetic force of the first magnet and the second magnet. The sliding block slides upward along the inner side of the slide groove through the elastic force of the second telescopic spring. When the sliding block slides upward, it drives the support rod to rotate. The dust cover is lifted up by the rotation of the support rod and fixed vertically at 90° to the outside of the instrument body to prevent dust on the upper surface of the mine from falling to the inside of the instrument body.

When the dust cover 20 is attached to the outer surface of the instrument body 5, the magnetic force of the first magnet 25 and the second magnet 27 fixes the dust cover 20 to the outside of the instrument body 5. When the instrument body 5 needs to be used, the dust cover 20 is manually pulled to separate the first magnet 25 and the second magnet 27.
