Description

Technical Field

[0001] The utility model belongs to the technical field of geophones, in particular to a geophone fixing device. Background Art

[0002] A geophone is a device that detects some useful information in a wave signal. It is used to identify the presence or change of waves, oscillations or signals. Geophones are usually used to extract the information they carry. They are widely used in geological surveys and engineering surveys. In real life, when using a detector to inspect tunnel quality, it is usually necessary to fix the geophone on the tunnel wall through a retaining device. However, since most retaining devices are not equipped with a limit assembly, it is impossible to limit the connected geophone. When the retaining device is installed offset, the geophone is easy to fall off the retaining device, which can easily cause damage to it.

[0003] A Chinese patent document (application publication number CN215680239U) discloses a fixing device for a tunnel geophone, which includes a geophone, a container and a base. The base is fixed to the tunnel, the geophone is arranged in the container, a T-block is arranged on the container, and a T-slot matched with the size of the T-block is arranged on the base. The T-block and the T-slot constitute the fixing of the container and the base.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks a limiting component. When the detector is fixed in place by the base, if the base is fixed in the tunnel and the position is offset and tilted, the connected detector is easy to fall off the base, which can easily cause damage to it. Utility Model Content

[0005] The utility model aims to provide a detector retaining device to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detector fixing device, comprising a mounting base for fixing the detector, a placing plate is installed at the bottom end of the front side of the mounting base, a detector assembly is provided on the top of the placing plate, fixing blocks are installed at the bottom ends of both sides of the mounting base, fixing rods are installed at the tops of the two fixing blocks, elastic blocks are installed on the outer walls of the two fixing rods, connecting rods are installed at one end of the two elastic blocks, a pressure plate for limiting the detector is commonly provided on the tops of the two connecting rods, a buffer assembly is provided at the bottom end of the pressure plate, and the pressure plate contacts the detector assembly through the buffer assembly.

[0007] As a preferred embodiment, the buffer assembly includes three first springs, and the bottom ends of the three first springs are commonly provided with a connecting plate.

[0008] As a preferred embodiment, the detector assembly includes a protection block for protecting the detector, a mounting hole is provided on the front side of the protection block, and a detector body is provided on the inner wall of the mounting hole.

[0009] As a preferred embodiment, a pad for auxiliary buffering of the detector assembly is installed on the top of the placement plate.

[0010] As a preferred embodiment, the top end of the connecting rod passes through the top end of the fixing rod, a second spring is installed at the bottom end of the connecting rod, and the bottom end of the second spring is fixedly connected to the inner bottom end of the fixing rod.

[0011] As a preferred embodiment, a guide slider for guiding the installation of the detector assembly is installed on the back side of the protection block.

[0012] As a preferred embodiment, fixing seats for connecting and fixing the mounting seat are installed on both sides of the upper and lower ends of the mounting seat.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The detector retaining device benefits from the design of the pressure plate, the connecting rod and the elastic block. After the elastic block is pressed inward and the pressure plate is moved upward, the detector assembly is aligned and installed on the front of the mounting seat, and the elastic block is again engaged with the clamping hole located below the fixing rod. In this way, the detector can be protected from falling due to the tilt and deviation of the mounting seat, thereby protecting the detector.

[0015] By providing the first spring, the connecting plate and the pad, after the detector is fixed on the mounting seat, under the joint action of the first spring, the connecting plate and the pad, the detector can be buffered and protected when the mounting seat is vibrated, avoiding damage to the detector and thus increasing its service life.
