Description

Technical Field

[0001] This invention relates to the field of earthquake monitoring technology, specifically to an underwater earthquake monitoring device. Background Technology

[0002] Currently, with the strengthening of human economic activities and the expansion of their scope, the demand for energy and security is constantly increasing, leading to more frequent underwater activities and a continuous rise in the construction and investment in underwater engineering. However, submarine seismic activity is extremely frequent and can easily cause significant damage to underwater engineering equipment. Therefore, it is necessary to use underwater seismic monitoring devices to monitor underwater seismic information in real time.

[0003] However, the existing monitoring devices still have the following technical problems when in use:

[0004] (1) When the existing monitoring device is placed underwater for monitoring, its anti-collision capability is poor. When a foreign object collides with the monitoring device, it is easy to damage the monitoring device.

[0005] (2) As the device is placed underwater for a long time, a lot of moss or mud will accumulate on the side wall of the protective netting outside the monitoring device. The current monitoring device does not have an automatic cleaning device. A lot of moss or mud will block the protective netting and affect the normal signal reception of the monitoring device.

[0030] Example:

[0031] Please see Figure 1-7 The present invention provides a technical solution:

[0032] An underwater earthquake monitoring device includes a floating platform 1. The side wall of the floating platform 1 has a cavity. A winding mechanism is fixed to the upper side of the floating platform 1. A bracket 2 is fixed to the lower end of the winding mechanism. A first mounting block 3 is fixed to the front and rear sides of the bracket 2. A first bolt is threaded to the side wall of the first mounting block 3. A base plate 4 is fixed to the lower end of the bracket 2 by the first bolt. The winding mechanism is used to wind or unwind the connecting rope 19, thereby realizing the lifting and lowering of the monitoring device body 5.

[0033] The monitoring device body 5 is fixed on the upper side of the base plate 4, and the annular plate 6 is fixed on the upper side of the base plate 4. The left and right sides of the annular plate 6 are threaded with second bolts. The protective mesh cover 7 is fixed inside the annular plate 6 by the second bolts. The lower side of the protective mesh cover 7 contacts the upper side of the base plate 4. The side wall of the protective mesh cover 7 has evenly arranged holes, so it will not affect the signal reception of the monitoring device body 5. The monitoring device body 5 here is conventional technology in the field, so it is not described in detail in this application. The monitoring device body 5 has a power supply inside and is waterproof.

[0034] A rotating mechanism is fixed at the upper end of the protective net cover 7. A rotating plate 8 is fixed at the upper end of the rotating mechanism. A first cavity is opened inside the rotating plate 8. A connecting mechanism is fixed inside the first cavity. An installation plate 9 is fixed to the right end of the rotating plate 8 through the connecting mechanism. A cleaning brush 10 is fixed to the right side of the installation plate 9. The rotating mechanism drives the rotating plate 8 to rotate, and the rotating plate 8 drives the installation plate 9 on the side wall and the cleaning brush 10 to rotate, thereby processing the mesh of the protective net cover 7.

[0035] The left, right, front and rear ends of the base plate 4 are all provided with second cavities. The second cavities are provided with buffer mechanisms. The left, right, front and rear ends of the base plate 4 are all fixed with buffer plates 11 by buffer mechanisms. The side walls of the buffer plates 11 are provided with grooves. The inside of the grooves is rotatably connected to the buffer column 12 by a shaft pin. When an external stone hits the monitoring device body 5, the external force can be effectively buffered by the buffer mechanism and the buffer plate 11 to avoid damage to the monitoring device body 5.

[0036] The winding mechanism includes two support rods 13, the lower ends of which are fixedly connected to the upper side of the floating platform 1. A storage box 14 is fixedly attached to the upper ends of both support rods 13. A dual-axis motor 15 is fixedly attached to the upper end of the storage box 14. Transmission rods 16 are fixed to the left and right ends of the dual-axis motor 15.

The two first pulleys are rotatably connected to the two second pulleys through belts. A connecting rope 19 is wound around the outside of the winding roller 18. A fixing ring 20 is fixed at the lower end of the connecting rope 19. The lower side of the fixing ring 20 is fixedly connected to the upper side of the bracket 2. The dual-axis motor 15 is a forward and reverse motor, so it can not only wind the connecting rope 19 but also unwind it, realizing the lifting and lowering of the bottom plate 4. The bottom plate 4 is made of metal material and will not easily change position when it sinks to the bottom of the water.

[0037] The upper side of the base plate 4 is fixed with a mounting bracket 21 by a third bolt, and the two mounting brackets 21 are fixedly connected to the monitoring device body 5 by a fourth bolt on the side that is close to each other.

A motor 23 is fixed inside the waterproof housing 22, and a vertical rod 24 is fixed to the output end of the motor 23. The vertical rod 24 is rotatably connected to the upper side of the waterproof housing 22 and the protective mesh cover 7. The upper end of the vertical rod 24 is fixedly connected to the lower side of the rotating plate 8. The motor 23 drives the vertical rod 24 at the output end to rotate, which in turn drives the rotating plate 8 at the upper end to rotate. The rotating plate 8 then drives the mounting plate 9 and the cleaning brush 10 to rotate.

[0039] The connecting mechanism includes a slider 25, which is slidably connected inside the first cavity. A first spring 26 is fixed to the left side of the slider 25, and the left end of the first spring 26 is fixedly connected to the inner wall of the first cavity. A connecting rod 27 is fixed to the right side of the slider 25. The connecting rod 27 extends through the right side of the first cavity to the outside and is fixed to a second mounting block 28. The second mounting block 28 is fixedly connected to the mounting plate 9 by a fifth bolt. The connecting mechanism can ensure that the cleaning brush 10 fits tightly against the side wall of the protective mesh cover 7.

[0040] The buffer mechanism includes a limiting block 29, which is disposed inside the second cavity. A limiting rod 30 is fixed to the side wall of the limiting block 29. The limiting rod 30 is slidably connected to the side wall of the second cavity, and one end of the limiting rod 30 extending to the outside is fixedly connected to the side wall of the buffer plate 11. A second spring 31 is sleeved on the outside of the limiting rod 30. One end of the second spring 31 is fixedly connected to the side wall of the limiting block 29, and the other end of the second spring 31 is fixedly connected to the inner wall of the second cavity.

[0041] Working principle:

[0042] In use, the floating platform 1 is placed and floated on the water surface. The connecting rope 19 is unwound by the winding mechanism, so that the bottom plate 4 and the monitoring device body 5 at the lower end descend to the bottom of the water. The monitoring device body 5 monitors the seismic wave information at the bottom of the water in real time. During use, if moss or mud at the bottom of the water adheres to the mesh of the protective net cover 7 and affects the signal reception of the monitoring device body 5, the rotating mechanism can drive the rotating plate 8 to rotate. The rotating plate 8 drives the mounting plate 9 on the side wall and the cleaning brush 10 to rotate, thereby cleaning the protective net cover 7 and ensuring high-quality reception of seismic wave signals.

[0043] Furthermore, during the monitoring process, if a stone rolls and collides with the buffer plate 11, the buffer mechanism can effectively buffer the external force and prevent damage to the monitoring device body 5.

[0044] During the monitoring process, it is necessary to perform regular maintenance. At this time, the connecting rope 19 needs to be wound by the winding mechanism to lift the bottom plate 4 and the monitoring device body 5 at the lower end, and the protective net cover 7 and the monitoring device body 5 need to be disassembled and the monitoring device body 5 needs to be maintained.
