Description

Technical Field

[0001] The utility model belongs to the technical field of detectors, in particular to an ultra-low frequency detector. Background Art

[0002] A geophone is a device that detects some useful information in a wave signal. It is used to detect the presence or change of waves, oscillations or signals. Geophones are usually used to extract the information they carry. In real life, for some ultra-low frequency geophones used outdoors, the tail cone is usually inserted into the ground during installation. Since most geophones are not equipped with auxiliary positioning mechanisms, when encountering severe weather such as strong winds, the geophone is prone to shaking, affecting the coupling effect between the tail cone and the ground, thereby reducing its overall stability.

[0003] A Chinese patent document (application publication number CN209765067U) discloses a novel ultra-low frequency seismic geophone, which includes a geophone body, the bottom of which is symmetrically fixedly connected with two first fixing seats, the bottom of which is hinged with a connecting rod, one end of which is away from the bottom of the first fixing seat and hinged with a second fixing seat, a base is provided below the geophone body, and two grooves are symmetrically provided on both sides of the upper surface of the base.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks an auxiliary positioning mechanism and cannot provide auxiliary support for the detector after it is inserted into the ground. When encountering severe weather such as strong winds, it is easy to cause the detector to shake, affecting the coupling effect between the tail vertebrae and the ground, thereby reducing its overall stability. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultra-low frequency detector, comprising an ultra-low frequency detector body, the outer wall of the ultra-low frequency detector body is provided with a fixing sleeve, connecting blocks are installed on both sides of the outer wall of the fixing sleeve, the outer walls of the two connecting blocks are jointly provided with a connecting sleeve, one side of the connecting sleeve is provided with two first fixing components, support plates are installed on both sides of the bottom end of the connecting sleeve, one side of the inner bottom end of the two support plates is provided with a second fixing component, and the other side of the inner bottom end of the two support plates is provided with a load-bearing block for increasing the stability of the device.

[0007] As a preferred embodiment, the first fixing assembly includes a clamping rod, a spring is sleeved on one side of the outer wall of the clamping rod, the other side of the outer wall of the clamping rod passes through one side of the connecting sleeve, a fixing block is installed at one end of the clamping rod, and the other end of the clamping rod is clamped and connected with one side of the connecting block.

[0008] As a preferred embodiment, the second fixing assembly includes a screw rod, the outer wall of the screw rod passes through the support plate, a torsion bar is installed at the top end of the screw rod, and a conical head is installed at the bottom end of the screw rod.

[0009] As a preferred embodiment, guide blocks are installed on the inner side walls of the connecting sleeves.

[0010] As a preferred embodiment, one end of the spring is fixedly connected to one side of the fixing block, and the other end of the spring is fixedly connected to one side of the connecting sleeve.

[0011] As a preferred embodiment, a tail cone is installed at the bottom end of the ultra-low frequency detector body.

[0012] As a preferred embodiment, the other end of the clamping rod is semicircular and does not contact the guide block.

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

[0014] The ultra-low frequency geophone benefits from the design of the connecting sleeve, the support plate, the second fixing assembly and the bearing block. After the supporting plate is fixed by the second fixing assembly, the geophone is inserted into the ground through the connecting sleeve until the geophone is fixed to the connecting sleeve. In this way, the geophone can be auxiliary positioned to avoid the overall stability of the geophone being affected by severe weather such as strong winds. At the same time, under the action of the bearing block, the overall stability can be further increased.

[0015] By providing a first fixing component and a connecting sleeve, the first fixing component is opened, and the detector is moved upward until its bottom end is separated from the connecting sleeve. This method facilitates the disassembly and assembly of the auxiliary positioning device, so that the detector and the auxiliary positioning device are separately arranged, which is convenient for carrying and use.

The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0028] The present embodiment provides a first fixing assembly 5 including a clamping rod 501, one side of the outer wall of the clamping rod 501 is sleeved with a spring 502, the other side of the outer wall of the clamping rod 501 passes through one side of the connecting sleeve 4 and is slidably connected to the connecting sleeve 4, one end of the clamping rod 501 is installed with a fixing block 503, the other end of the clamping rod 501 is clamped and connected with one side of the connecting block 3, one side of the connecting block 3 is provided with a clamping hole adapted to the clamping rod 501, the clamping rod 501 is clamped and connected with the connecting block 3 through the clamping hole, one end of the spring 502 is fixedly connected with one side of the fixing block 503, and the other end of the spring 502 is fixedly connected with one side of the connecting sleeve 4, the fixing block 503 is pulled outward, and the fixing block 503 drives the clamping rod 501 to move outward until one end of the clamping rod 501 is separated from the connecting block 3, and then the detector is moved upward until its bottom end moves out of the connecting sleeve 4, in this way, the auxiliary positioning device is convenient to disassemble and assemble, and the detector and the auxiliary positioning device are separately arranged, which is convenient to carry and use.

[0029] The second fixing assembly 7 provided in this embodiment includes a screw rod 702, the outer wall of the screw rod 702 passes through the support plate 6 and is connected to the internal thread of the support plate 6, a knob 701 is installed at the top of the screw rod 702, and the outer wall of the knob 701 is provided with an anti-slip thread to increase the friction between the human hand and the knob 701, so as to facilitate the rotation of the knob 701, and a conical head 703 is installed at the bottom end of the screw rod 702.

[0030] The present embodiment provides that the inner side wall of the connecting sleeve 4 is installed with a guide block 9. The guide block 9 is rectangular in shape, and can also be T-shaped or other shapes. It is not limited here, as long as it can guide the detector. A guide groove compatible with the guide block 9 is opened on the opposite side of the two connecting blocks 3. The guide block 9 is slidably connected to the guide groove.

The bottom end of the ultra-low frequency detector body 1 is installed with a tail vertebra 8, and the other end of the clamping rod 501 is semicircular and does not contact the guide block 9.

[0031] How it works

[0032] Move the connecting sleeve 4 to the designated position, and make the two supporting plates 6 fit the ground, then rotate the knobs 701 respectively, and the rotating knobs 701 drive the conical head 703 to rotate downward through the screw rod 702 until the conical head 703 and the screw rod 702 are inserted into the ground, and then align the connecting block 3 connected to the outer wall of the ultra-low frequency detector body 1 and snap it to the inner wall of the connecting sleeve 4. When the connecting block 3 slides downward along the inner wall of the connecting sleeve 4 and contacts one end of the clamping rod 501, it will drive one end of the clamping rod 501 to move outward, and one end of the clamping rod 501 moves outward through the fixing block 503 stretches the spring 502 until the clamping hole on one side of the connecting block 3 and one end of the clamping rod 501 are located in the same plane. At this time, the clamping rod 501 is driven to move in the opposite direction under the elastic action of the spring 502, so that the clamping rod 501 is clamped with the connecting block 3 through the clamping hole. At this time, the tail vertebra 8 at the bottom end of the ultra-low frequency detector body 1 is also inserted into the ground. In this way, the detector can be auxiliary positioned to avoid the overall stability of the detector being affected by severe weather such as strong winds. At the same time, under the action of the load-bearing block 10, the overall stability can be further increased.
