Description

Technical Field

[0001] The present invention relates to the technical field of earthquake monitoring, and in particular to a protective device for field earthquake monitoring equipment. Background Art

[0002] Earthquake monitoring refers to the monitoring and measurement of earthquake precursor anomalies and seismic activities before and after an earthquake occurs. Earthquake monitoring equipment is an instrument that records ground movement. It can monitor and record ground movement at all times and record the ground movement process in the form of a waveform. According to the characteristics and travel time of the earthquake waveform, the time of the earthquake, the epicenter, the focal depth, the magnitude and other earthquake parameters can be calculated, and it can be determined whether it is a local earthquake, a near earthquake, a distant earthquake or an extremely distant earthquake. Real-time monitoring and recording of earthquakes through earthquake monitoring equipment can reduce the damage caused by earthquakes.

[0003] Earthquake monitoring equipment usually consists of two parts, namely a seismometer (seismic pickup) and a recorder. A seismometer, also called a seismic pickup, is a sensor that receives ground motion. It is generally divided into three directions (horizontal north-south, horizontal east-west, and vertical) to detect ground motion and convert it into electrical signal output. The recorder amplifies and records the ground motion signal output by the seismometer.

[0004] Earthquake monitoring equipment is usually installed in the wild area. It is inserted into the ground, enabling it to detect ground movement in real time and convert the ground movement into electrical signal output. Earthquake monitoring equipment that is usually installed at the liquid level is often dismantled or damaged by humans, resulting in the equipment being unable to be used normally. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-4As shown, this embodiment provides a protective device for outdoor earthquake monitoring equipment, including a shell 1, the side wall of the shell 1 is rotatably connected to a plurality of rotating rods 2, the bottom ends of the plurality of rotating rods 2 are fixedly connected to a spiral head 3, the top end of the rotating rod 2 is slidably connected to a first gear 5, the first gear 5 is meshed with an anti-disassembly component, the top surface of the shell 1 is buckled with a top shell 4, the anti-disassembly component is located on the top shell 4, the side walls of the shell 1 and the top shell 4 are provided with fixings, and the earthquake monitoring equipment is installed in the shell 1.

[0027] The present invention installs the earthquake monitoring equipment inside the shell 1. When the protective device is installed on the ground, the first gear 5 is driven to rotate by the anti-disassembly component, the first gear 5 drives the rotating rod 2 to rotate, the rotating rod 2 drives the spiral head 3 to rotate, and the spiral head 3 is screwed into the soil. After the spiral head 3 enters the soil in a screwed manner, it has a large anti-pull-out force on the soil, so that the protective device can be effectively fixed on the ground, and an anti-disassembly component is arranged on the top shell 4. The first gear 5 is arranged inside the top shell 4. The spiral head 3 can only be driven to reverse by the anti-disassembly component, which can effectively prevent the protective device from being removed manually.

[0028] A further optimized solution is that the anti-disassembly component includes a connecting shaft 11 rotatably connected to the center of the top surface of the top shell 4, the bottom end of the connecting shaft 11 is axially connected to a second gear 10, and the top surface of the connecting shaft 11 is contacted with a first disassembly rod 9. The first disassembly rod 9 is detachably installed in the rotating shaft hole of the connecting shaft 11 through a disassembly limiting component.

[0029] A further optimized solution is that the disassembly limiting component includes two symmetrically arranged first snap-fit ​​shells 7, a first dovetail groove 6 is opened on the top surface of the top shell 4, the first snap-fit ​​shell 7 is slidably connected in the first dovetail groove 6, a limiting hole is opened at the center of the two first snap-fit ​​shells 7, the first disassembly rod 9 is connected in the limiting hole for limited rotation, the docking surface of the first disassembly rod 9 and the connecting shaft 11 is an irregular surface, and a first clamp 8 is sleeved on the outside of the two first snap-fit ​​shells 7.

[0030] The rotating rod 2 and the first gear 5 can be splined, so that the rotating rod 2 can be ensured to move up and down and rotate. When the protective device needs to be fixed to the ground, the two first buckling shells 7 are slidably installed in the first dovetail groove 6, and then the first disassembly rod 9 is installed in the limiting hole. At this time, the two first buckling shells 7 limit the first disassembly rod 9, and an annular groove is opened on the side of the first disassembly rod 9, so that the annular groove matches the limiting hole, so that the first disassembly rod 9 can be rotated but cannot move up and down. This setting is considered that the spiral head 3 is subjected to a relatively large force when it is screwed into the soil surface, which can prevent the first disassembly rod 9 from axial movement when it is docked with the connecting shaft 11. Since the lock core structure is used for anti-disassembly, the lock core can still be manually broken. Therefore, the first disassembly rod 9 and the connecting shaft 11 are connected with irregular surfaces, so that the uniqueness of the docking surface between the first disassembly rod 9 and the connecting shaft 11 can be ensured, and this docking drive method is much more difficult to crack than the lock core structure.

[0031] Further optimizing the scheme, a square head is provided at the top of the first disassembly rod 9. The setting of the square head can facilitate the first disassembly rod 9 to be rotated by other auxiliary tools.

[0032] In a further optimized solution, the fixing member includes a plurality of screw holes 401 formed on the side wall of the top shell 4, and screws are connected to the inner threads of the screw holes 401. The use of screws can facilitate the disassembly of the top shell 4 relative to the outer shell 1, so as to facilitate later maintenance.

[0033] Embodiment 2:

[0034] Reference Figure 5 As shown, the protection device of this embodiment is different from that of the first embodiment only in that the end face of the screw does not exceed the outer side wall of the side wall of the top shell 4, and the outer side wall of the top shell 4 is provided with a screw anti-disassembly member.

[0035] The screw anti-disassembly component includes a second disassembly rod 15 connected to the end face of the screw. The end face of the second disassembly rod 15 connected to the screw is an irregular surface. The second disassembly rod 15 is detachably mounted on the outer side wall of the top shell 4 through a stabilizing member.

[0036] The stabilizing member includes two symmetrically arranged second snap-fit ​​shells 13, a second dovetail groove 12 is provided on the side wall of the top shell 4, the second snap-fit ​​shell 13 is slidably arranged in the second dovetail groove 12, a second clamp 14 is sleeved on the outer side of the second snap-fit ​​shell 13, a rotating groove is provided at the center of the two second snap-fit ​​shells 13 where they are connected, and a second disassembly rod 15 is movably arranged in the rotating groove.

[0037] The second disassembly rod 15 in this embodiment also adopts an irregular surface to connect with the screw, and the specific principle of disassembling the screw is similar to the principle of the first disassembly rod 9 driving the connecting shaft 11 in the embodiment. The difference is that considering that the screw will be displaced in the axial direction when screwing into or out of the screw hole 401, the second disassembly rod 15 and the two second buckle shells 13 are movably arranged, so that the second disassembly rod 15 can be rotated or moved in the axial direction. When the second disassembly rod 15 disassembles or installs the screw, a low-speed hand drill or a sleeve wrench can be used, and any tool that can apply rotational and axial forces to the second disassembly rod 15 can be used, so that the top shell 4 can be effectively prevented from being disassembled relative to the outer shell 1. Compared with the first embodiment, it can effectively prevent the protective device from being removed manually.

[0038] For further convenience of use, the first disassembly rod 9 and the second disassembly rod 15 can be set to rods of the same specifications, and the shapes of the surfaces where the first disassembly rod 9 and the second disassembly rod 15 meet can be set to the same irregular surfaces. In this way, only one rod is required to realize both the driving of the connecting shaft 11 and the disassembly and assembly of the screws.

[0039] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
