[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following further describes the present utility model in detail with reference to the drawings.
[0021] As Figures 1-5 shown, an underwater seismic monitoring device proposed by the present utility model includes a geophone 1, a waterproof housing 2, and a protection component 3. The geophone 1 is arranged in the waterproof housing 2. A floating plate 4 is fixedly arranged on the bottom wall of the waterproof housing 2, and a fixing member 5 is arranged at the bottom of the floating plate 4. The protection component 3 includes a connecting shaft 6 and a roller. A circumferentially distributed groove 8 is formed at the edge position of the floating plate 4. The bottom end of the connecting shaft 6 is rotatably arranged in the groove 8 through a shaft. The top end of the connecting shaft 6 is movably connected with a buffer member 9, and the buffer member 9 is movably connected with the waterproof housing 2. A roller 7 is rotatably arranged on the connecting shaft 6. The device is fixed underwater through the fixing member 5. When there is an external impact, the roller 7 rotates after being stressed, thereby performing the first layer of buffering, and then cooperating with the buffer member 9 to achieve the second layer of buffer protection, ultimately protecting the waterproof housing 2 and the geophone 1 inside it.
[0022] As Figure 3 shown, the buffer member 9 includes a damper 10 and a spring 11. The top end of the damper 10 is rotatably connected to the connecting shaft 6 through a shaft, the bottom end of the damper 10 is hinged to the side wall of the waterproof housing 2, and the spring 11 is sleeved on the damper 10.
[0023] As Figure 3 shown, a rolling ball 12 is rotatably arranged on the outer edge of the floating plate 4 and between adjacent grooves 8. After the rolling ball 12 is subjected to an impact force, under the action of a tangential force, it protects the floating plate 4.
[0024] As Figure 4 shown, the fixing member 5 includes a floating seat 13 made of rubber material. The floating seat 13 is arranged at the bottom of the floating plate 4. A counterweight seat 14 is arranged at the bottom of the floating seat 13, and a single ear 17 is arranged on the bottom wall of the counterweight seat 14. The device can be fixed in water through the single ear 17, and further protection can be achieved through the elastic force and buoyancy of the floating seat 13 itself.
[0025] As Figure 4As shown in the figure, a waterproof cover 15 is threadedly connected to the top of the waterproof housing 2. A pull ring 16 is provided on the waterproof cover 15. Both the waterproof housing 2 and the waterproof cover 15 are made of high-strength and corrosion-resistant materials, which is convenient for opening the waterproof cover 15 and taking out the geophone 1.
[0026] During specific use, the device is fixed underwater through the single ear 17 in cooperation with an external installation tool. When there is an external impact, the roller 7 rotates under the action of the impact force to perform the first layer of buffering. Then, in cooperation with the damper 10, compression occurs, and the spring 11 undergoes elastic deformation to perform impact buffering, realizing the second layer of buffer protection to protect the waterproof housing 2 and the geophone 1 inside it.
[0027] Meanwhile, the buoyancy of the floating seat 13 and the floating plate 4 can make the geophone 1 and the waterproof housing 2 float in the water, and the elasticity of the floating seat 13 can further protect against impacts from underwater organisms and reefs.
[0028] The above description is made for the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
