Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine geological engineering monitoring equipment technology, and in particular to a marine geological engineering monitoring and early warning device. Background Technology
[0002] Marine engineering geological monitoring is a crucial link in ensuring the safety and sustainable development of marine engineering projects. Currently, monitoring is often conducted by deploying monitoring instruments into the sea. Self-contained hydrophones are a commonly used marine engineering monitoring instrument; their specific structure can be found in the appendix. Figure 1 It can not only monitor ocean conditions through multiple sensors, collect and store information to provide early warning for seabed engineering, but also has its own power storage and can supply power autonomously.
[0003] Currently, most self-contained hydrophones are either placed directly into the sea or suspended from external supports and extended into the water for monitoring. This not only makes them susceptible to impacts from marine life, affecting the monitoring results, but also sacrifices the ability to directly collect some geological data once the instrument is fixed in place, impacting the effectiveness of monitoring and early warning. Furthermore, traditional instruments require complex recovery equipment or manual diving for retrieval, which is inconvenient. Therefore, there is a need for a marine geological engineering monitoring and early warning device that is easy to protect and recover.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the problem that existing self-contained hydrophones, when used for monitoring seabed engineering, lack suitable protection and retrieval structures, making them susceptible to collisions with marine organisms and inconvenient for monitoring and retrieval, this invention provides a marine geological engineering monitoring and early warning device.
[0006] The marine geological engineering monitoring and early warning device provided by this utility model adopts the following technical solution:
[0007] A marine geological engineering monitoring and early warning device includes a storage module and a monitoring module. One side of the storage module is connected to the monitoring module via a connecting rope. The storage module has a storage battery and an information storage element inside. The monitoring module integrates multiple environmental monitoring sensors. A protective cage is provided on the outside of the storage module and the monitoring module. The bottom of the protective cage is open, and its four walls are fixed with grid plates. The top of the protective cage is symmetrically provided with rotating plates that can rotate around a fixed rod. The two ends of the fixed rod are fixed to the protective cage. A pull rope is threaded between the two rotating plates. The lower end of the pull rope is sleeved on the connecting rope. Pulling the pull rope will retrieve the storage module and the monitoring module.
[0008] Furthermore, the top of the pulling rope is connected to a second float, the lower end of the pulling rope is fixed to a baffle, the baffle is located below the rotating plate, the bottom of the baffle is fixedly connected to the connecting bucket by a buffer rope, and the inner wall of the connecting bucket is fixed to a stop bar.
[0009] The middle of the connecting rope is located between the connecting bucket and the stop bar, and the buffer rope is curved to reduce the impact of the swaying of the traction rope on the storage module and the monitoring module.
[0010] Furthermore, the rotating plate is supported by a support plate of a fixed protective cage at its lower part, preventing the rotating plate from rotating downwards; the end of the rotating plate is sleeved on the outside of the fixed rod through a through hole, and a connecting groove is provided in the middle of the rotating plate. The lower end of the guide rope is sleeved on the connecting rod on the inner wall of the connecting groove through a connecting ring; the upper end of the guide rope is fixed with a first float.
[0011] Furthermore, a guide arc rod is fixed in the middle of one side wall of the rotating plate, and the pull rope is located on one side of the guide arc rod.
[0012] Furthermore, one end of the connecting rope is connected to the first buckle on the top of the storage module via a first loop;
[0013] The other end of the connecting rope is connected to the second buckle on the top of the monitoring module via a second loop.
[0014] Furthermore, the mesh size of the protective cage is less than 5cm, and the material is a corrosion-resistant metal alloy.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] (1) The protective cage set up in this scheme is a protective structure with an open bottom and four grid panels on the four sides. It is placed on the outside of the marine engineering monitoring instrument to reduce the impact of marine organism collisions on the monitoring results. At the same time, it allows water flow to pass through, reducing eddy current resistance. The open bottom design allows the monitoring instrument to directly contact the seabed, so that the monitoring instrument can fully perform its monitoring function. In addition, the protective cage and the instrument are designed separately to avoid the impact of the protective cage being transmitted to the instrument, further reducing external interference.
[0017] (2) The traction rope and guide rope set in this scheme have their lower ends passing through the rotating plate at the top of the protective cage and connected to the monitoring instrument. When the instrument is retrieved later, the traction rope is wound up to make the instrument move upward. After the rotating plate is opened, the instrument can be retrieved. The retrieval operation is convenient. The protective cage can be retrieved by connecting the guide rope. At the same time, floats are set at the top of both the traction rope and the guide rope for easy retrieval. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0024] Example 1: In this example, refer to Figure 1 and Figure 3 As shown, specifically, a marine geological engineering monitoring and early warning device includes a storage module 1 and a monitoring module 2. One side of the storage module 1 is connected to the monitoring module 2 via a connecting rope 3. One end of the connecting rope 3 is connected to the first buckle 11 on the top of the storage module 1 via a first loop 31; the other end of the connecting rope 3 is connected to the second buckle 21 on the top of the monitoring module 2 via a second loop 32. The two instruments are connected via the connecting rope 3, avoiding the problem of insufficient strength when the instruments are only connected by a guide. The storage module 1 is equipped with a storage battery and an information storage element inside, which can power the device and extend its endurance. At the same time, the information storage element can receive and store monitoring information for easy retrieval after the instrument is recovered. The monitoring module 2 integrates multiple environmental monitoring sensors to monitor various information of marine engineering, which is convenient for retrieval and early warning of marine engineering. The specific structure and operating principle of the above instruments can refer to the self-contained hydrophone in the prior art, which is a common existing technology, so it is not described in detail here.
[0025] Reference Figure 2 , Figure 3 and Figure 4As shown, specifically, a protective cage 4 is provided on the outside of the storage module 1 and the monitoring module 2. The bottom of the protective cage 4 is open to facilitate the instrument to contact the seabed. The four walls are fixed with grid plates 41. The grid plates 41 of the protective cage 4 have a hole diameter of less than 5cm to prevent large marine organisms from colliding with the instrument. At the same time, seawater flow is allowed to reduce eddy current resistance. The material is a corrosion-resistant metal alloy with high strength and stable placement. The top of the protective cage 4 is symmetrically provided with rotating plates 42 that can rotate around the fixed rod 45. The two ends of the fixed rod 45 are fixed to the protective cage 4.
[0026] Specifically, through the above technical solution, when using the monitoring instrument to monitor marine engineering information, a protective cage 4 is set on the outside of it, which can reduce the impact of marine organisms on the monitoring. At the same time, the open bottom allows the instrument to be placed stably on the seabed without affecting the full function of the instrument. In addition, the protective cage 4 is not fixed to the instrument, which avoids the impact on the protective cage 4 being transmitted to the instrument, thus improving the stability of the instrument monitoring.
[0027] Example 2: In this example, refer to Figure 3 and Figure 4 As shown, specifically, a pull rope 5 is threaded between the two rotating plates 42. It is made of high-strength and corrosion-resistant material. A guide arc rod 424 is fixed in the middle of one side wall of the rotating plate 42. The arc structure does not affect the movement of the pull rope 5. The pull rope 5 is located on one side of the guide arc rod 424. The lower end of the pull rope 5 is sleeved on the connecting rope 3. Pulling the pull rope 5 will retrieve the storage module 1 and the monitoring module 2. The top of the pull rope 5 is connected to the second float 51, and the position of the equipment is marked by the float.
[0028] Specifically, the storage module 1 and the monitoring module 2 are connected by the connecting rope 3, and the traction rope 5 is connected to the connecting rope 3. When retrieving the instrument later, simply pull the traction rope 5 to lift the instrument up and push open the rotating plate 42 for retrieval. The retrieval operation is convenient.
[0029] Reference Figure 3 and Figure 4 As shown, specifically, a baffle 52 is fixed to the lower end of the pull rope 5. The baffle 52 is located below the rotating plate 42. The rotating plate 42 can block the lower end of the pull rope 5 to prevent the seawater from causing the float and the upper part of the pull rope to sway, affecting the stability of the instrument. The bottom of the baffle 52 is fixedly connected to the connecting bucket 54 through a buffer rope 53. A stop bar 55 is fixed to the inner wall of the connecting bucket 54. The middle part of the connecting rope 3 is located between the connecting bucket 54 and the stop bar 55. The buffer rope 53 is curved and can be made of high-strength elastic material and has a certain length.
[0030] Specifically, by using the buffer rope 53, when the upper part of the pull rope 5 or the protective cage 4 shakes and comes into contact with the pull rope 5, the long and curved buffer rope 53 provides stretching and buffering, preventing external forces from acting directly on the monitoring instrument, reducing the impact of the pull rope 5 shaking on the storage module 1 and the monitoring module 2, and further improving the monitoring stability.
[0031] Example 3: In this example, refer to Figure 3 and Figure 4 As shown, specifically, the lower part of the rotating plate 42 is supported by the support plate 44 of the fixed protective cage 4, preventing the rotating plate 42 from rotating downwards while not affecting its upward rotation; the end of the rotating plate 42 is sleeved on the outside of the fixed rod 45 through the through hole 421, and the middle part of the rotating plate 42 is provided with a connecting groove 422. The lower end of the guide rope 43 is sleeved on the connecting rod 423 on the inner wall of the connecting groove 422 through the connecting ring 432; the upper end of the guide rope 43 is fixed with the first float 431, which guides and positions the protective cage 4. The protective cage 4 can be retrieved by pulling the guide rope 43. In addition, when it is necessary to place the monitoring instrument here again, the guide rope 43 can be straightened to open the rotating plate 42, and then the monitoring instrument can be placed along the lower part of the guide rope 43 and adjusted by the camera element installed on it, making it easy to place the instrument inside the protective cage 4 again.
[0032] Working Principle: When using the monitoring instrument to monitor marine engineering projects, the operator rotates the protective cage 4 to open the rotating plate 42. Then, the storage module 1 and monitoring module 2 of the instrument are placed inside the protective cage 4, so that the traction rope 5 connected to the top of the instrument passes between the two rotating plates 42. At the same time, the baffle 52 at the lower end of the traction rope 5 can be positioned below the rotating plate 42 to block it. Then, the operator releases the guide rope 43 and the traction rope 5, so that the protective cage 4 and the instrument fall to the seabed for monitoring. During monitoring, the protective cage 4 covers the outside of the instrument without contacting the instrument body, which can protect it from the impact of external marine life and does not interfere with the normal information collection of the instrument, thus improving the stability of monitoring. When the instrument is retrieved at a later time, the buoy is used to locate the position, and the traction rope 5 is wound up, so that the connecting rope 3 drives the two parts of the instrument to move upward, push open the rotating plate 42 of the protective cage 4, and then move upward for retrieval. The retrieval operation is convenient. After the instrument is retrieved, the operator reads and analyzes the collected information, thus realizing the monitoring and early warning of marine work.
