Description

Technical Field

[0001] This utility model relates to the field of earthquake detection technology, and in particular to an earthquake frequency detection device. Background Technology

[0002] A seismic detector is an electromechanical conversion device that converts seismic waves into electrical signals. It is a key component for seismographs in the field. Seismic detectors can directly pick up seismic vibrations and convert them into energy forms that can be recorded by the instrument.

[0003] Currently, electrodynamic seismographs are commonly used in onshore seismic exploration. These detectors consist of a permanent magnet, a coil, and spring plates. When mechanical vibrations occur on the ground, the coil moves relative to the magnet, cutting magnetic lines of force. Based on the principle of electromagnetic induction, an induced electromotive force (EMF) is generated in the coil. The magnitude of this EMF is proportional to the relative velocity between the coil and the magnet. The analog electrical signal output by the coil follows the same velocity variation pattern as the ground's mechanical vibrations, thus achieving the effect of seismic frequency detection.

[0004] When using an electric seismic detector, a hole is typically drilled in the ground, and the detector is then installed inside the hole. However, the top cover is usually exposed outside the ground, and the detector is installed via a tapered plug at the bottom. This can lead to water seepage into the hole during actual use, causing the detector to loosen and reducing its tightness against the hole wall, which can affect the detection of seismic frequency.

[0005] Therefore, this application provides an earthquake frequency detection device to meet the requirements. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an earthquake frequency detection device to address the issue that the installation effect of existing earthquake detectors needs further optimization during installation and use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An earthquake frequency detection device includes an electric geophone. The bottom of the electric geophone is provided with a plug-in part, and the top of the electric geophone is detachably installed with a protective cover. The edge of the protective cover is provided with a clamping edge for tightly pressing against the ground. A reinforcing bolt is provided on the clamping edge, and a buffer plate is elastically installed on the top of the protective cover.

[0009] A horizontal reinforcing hole is provided in the middle of the side of the plug-in part. A plate-shaped cone is provided at the lower end of the plug-in part. A vertical movable rod is fixed at the top of the plate-shaped cone. The movable rod is rotatably installed in the plug-in part, and a threaded section is constructed on the movable rod. A movable block is sleeved on the threaded section. The movable block moves up and down in the plug-in part. A connecting rod is hinged to the side of the movable block. A reinforcing cone is movably connected to the end of the connecting rod. The reinforcing cone is horizontally slidably installed in the reinforcing hole.

[0010] Optionally, the protective cover arches upward in the middle to form a frustum structure, and multiple grooves are provided on the side of the frustum structure.

[0011] Optionally, a rubber pad is fitted onto the upper surface of the buffer plate.

[0012] Optionally, the lower end face of the buffer plate is fixed with a plurality of vertical insertion posts, which are vertically inserted into the inner and outer peripheries of the protective cover.

[0013] Optionally, a plurality of springs are fixed to the middle of the upper end face of the protective cover, and the springs are supported on the lower end face of the buffer plate.

[0014] Optionally, a threaded cylinder is fixed in the middle of the protective cover, and the top outer edge of the electric detector is constructed with a threaded portion, which is adapted to the threaded cylinder.

[0015] Optionally, the upper end face of the protective cover has a cable outlet in the middle, and the cable outlet communicates with the inside of the threaded cylinder.

[0016] Optionally, the top of the electric detector is fixed with multiple cable tubes, with cables extending out of the cable tubes, passing through the outlet, and extending out through the gap between the protective cover and the buffer plate.

[0017] Optionally, a protrusion is fixed to the upper surface of the protective cover, the protrusion being used to maintain at least one gap between the protective cover and the buffer plate.

[0018] Optionally, a sealing gasket is provided between the reinforcing bolt and the clamping edge.

[0019] Compared with the prior art, this utility model has at least the following beneficial effects:

[0020] In the above scheme, by setting up the plug-in part, the plate-shaped cone can be inserted into the ground hole. With the plate-shaped structure of the plate-shaped cone, the movable rod at the top of the plate-shaped cone is controlled to rotate relative to each other by rotating the electric detector, so that the movable block moves up and down, thereby controlling the connecting rod to drive the reinforcing cone to extend out of the reinforcing hole, so that the reinforcing cone is inserted into the inner wall of the ground hole from the side to form reinforcement.

[0021] In the above solution, thanks to the protective cover, the snap-fit ​​edge can be used to fasten it to the ground, preventing water from flowing directly into the hole where the electric geophone is installed. In addition, the reinforcing bolts on the snap-fit ​​edge can further fix the electric geophone and the protective cover together in the hole in the ground.

[0022] In summary, this device can be firmly attached to the ground during installation and forms a horizontally inserted reinforcement structure inside the installation hole, thereby effectively improving the installation effect and ensuring the detection effect of earthquake frequency.

[0036] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides an earthquake frequency detection device, including an electric geophone 1. The bottom of the electric geophone 1 is provided with a plug-in part 2, and the top of the electric geophone 1 is detachably equipped with a protective cover 3. The edge of the protective cover 3 is provided with a clamping edge 301 for tightly fitting the ground. A reinforcing bolt 4 is provided on the clamping edge 301, and a sealing gasket is provided between the reinforcing bolt 4 and the clamping edge 301. A buffer plate 5 is elastically installed on the top of the protective cover 3, and a rubber gasket 501 is fitted on the upper end surface of the buffer plate 5.

[0037] Specifically, in coordination Figure 3 As shown, multiple vertical insertion posts 502 are fixed on the lower end face of the buffer plate 5. The insertion posts 502 are vertically inserted into the inner and outer peripheries of the protective cover 3. Multiple springs 6 are fixed in the middle of the upper end face of the protective cover 3. The springs 6 are supported on the lower end face of the buffer plate 5. A protrusion is fixed on the upper end face of the protective cover 3. The protrusion is used to maintain at least one gap between the protective cover 3 and the buffer plate 5. Multiple cable tubes 102 are fixed on the top of the electric detector 1. Cables extend out of the cable tubes 102. The cables pass through the outlet 7 and extend out through the gap between the protective cover 3 and the buffer plate 5.

[0038] In addition, a threaded cylinder 303 is fixed in the middle of the protective cover 3, and the top outer edge of the electric detector 1 is constructed with a threaded part 101, which is adapted to the threaded cylinder 303. A cable outlet 7 is opened in the middle of the upper end face of the protective cover 3, and the cable outlet 7 is connected to the inside of the threaded cylinder 303.

[0039] like Figure 4 As shown, a horizontal reinforcing hole 201 is provided in the middle of the side of the plug-in part 2. A plate-shaped cone 202 is provided at the lower end of the plug-in part 2. A vertical movable rod 203 is fixed at the top of the plate-shaped cone 202. The movable rod 203 is rotatably installed in the plug-in part 2, and a threaded section is constructed on the movable rod 203. A movable block 204 is sleeved on the threaded section. The movable block 204 moves up and down in the plug-in part 2. A connecting rod 205 is hinged to the side of the movable block 204. A reinforcing cone 206 is movably connected to the end of the connecting rod 205. The reinforcing cone 206 is horizontally slidably installed in the reinforcing hole 201.

[0040] In addition, the middle of the protective cover 3 arches upward to form a frustum structure, and multiple grooves 302 are opened on the side of the frustum structure.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] When using this seismic frequency detection equipment, the electric geophone 1 is placed in a pre-fabricated hole in the ground. The plate-shaped cone 202 is first inserted into the hole. The plate-shaped structure of the plate-shaped cone 202 is used to control the relative rotation of the movable rod 203 at the top of the plate-shaped cone 202 by rotating the electric geophone 1. This causes the movable block 204 to move downward in the insertion part 2 under the drive of the thread, so as to control the connecting rod 205 to drive the reinforcing cone 206 to extend out of the reinforcing hole 201. Thus, the reinforcing cone 206 is inserted into the inner wall of the hole in the ground from the side to form reinforcement.

[0043] Meanwhile, the protective cover 3 is threaded onto the top of the electric geophone 1 and secured to the ground using the snap-fit ​​edge 301 to prevent water from flowing directly into the hole where the electric geophone 1 is installed. In conjunction with the reinforcing bolt 4 provided on the snap-fit ​​edge 301, the electric geophone 1 and the protective cover 3 are further fixed together in the hole in the ground.

[0044] In summary, this device can be firmly attached to the ground during installation and forms a horizontally inserted reinforcement structure inside the installation hole, thereby effectively improving the installation effect and ensuring the detection effect of earthquake frequency.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
