For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0052] Such as Figures 1-12As shown in the figure, an embodiment of the present invention provides a deployment mechanism 100 for a ship detection device, which includes a shaft 1, a cage 2, a crane 4, and a controller. At least one guide rail assembly 12 is installed along the length direction of the inner wall of the shaft 1. The crane 4 can transport the cage 2 into the shaft 1 and drive the cage 2 to be in rolling connection with the guide rail assembly 12. The cage 2 carries the detection device and extends along the shaft 1 to reach a predetermined detection position, so as to realize the deployment of the detection device.

[0053] To solve the problem of low stability and safety of the existing ship cage in the shaft, as Figures 1-4 shown, at least one guide rail assembly 12 is installed along the length direction of the inner wall of the shaft 1. The cage 2 can be placed in the shaft 1 and is in sliding connection with the guide rail assembly 12; the cage 2 includes a cage body 21 and at least one roller mechanism 22, and the roller mechanism 22 is installed on the outer side of the cage body 21; wherein, the roller mechanism 22 includes two mounting plates 221, an inner roller 223 assembly, and an outer roller 225 assembly; the two mounting plates 221 are spaced apart and installed on the outer side wall of the cage body 21, and both the inner roller 223 assembly and the outer roller 225 assembly are installed between the two mounting plates 221, and the inner roller 223 assembly and the outer roller 225 assembly are arranged in sequence from the direction close to the cage body 21 to the direction away from the cage body 21, and there is a first gap 226 between the inner roller 223 assembly and the outer roller 225 assembly; there are two outer roller 225 assemblies, and the two outer roller 225 assemblies are arranged oppositely and are respectively connected to the two mounting plates 221, and there is a second gap 227 between the two outer roller 225 assemblies; the guide rail assembly 12 can be inserted into the first gap 226 and the second gap 227 to realize the rolling connection between the roller mechanism 22 and the guide rail assembly 12.

[0054] Based on the above structure, the present application uses the inner roller 223 assembly and the outer roller 225 assembly together to realize the insertion with the guide rail assembly 12, effectively increasing the contact area between the roller mechanism 22 and the guide rail assembly 12, and avoiding the accidental detachment of the roller mechanism 22; at the same time, the roller mechanism 22 is in rolling connection with the guide rail assembly 12, with small frictional resistance, ensuring the smoothness of the roller mechanism 22 during the rolling process; thus ensuring the stability and safety of the cage body 21 moving in the shaft 1.

[0055] In this embodiment, as Figure 4 shown, the cross-section of the guide rail assembly 12 is T-shaped, which includes a first guide rail 121 and a second guide rail 122. The first end of the first guide rail 121 is fixedly connected to the inner wall of the shaft 1, and the second end of the first guide rail 121 is fixedly connected to the second guide rail 122; at the same time, as Figure 1 , 2 , 3 shown, the first gap 226 and the second gap 227 form a T-shaped gap, and the T-shaped gap is adapted to the T-shaped guide rail assembly 12.

[0056] like Figure 1 As shown, when the guide rail assembly 12 is inserted into the T-shaped gap, the first guide rail 121 is inserted into the second gap 227, the second guide rail 122 is inserted into the first gap 226, the second guide rail 122 is tangent to the inner roller 223 assembly and the outer roller 225 assembly, and the roller mechanism 22 wraps the T-shaped guide rail assembly 12. The roller mechanism 22 and the T-shaped guide rail assembly 12 form a tight clamping connection, thereby increasing the contact area between the roller mechanism 22 and the guide rail assembly 12, avoiding shaking of the roller mechanism 22 during rolling, and thereby ensuring the stability of the cage body 21 during movement.

[0057] Preferably, Figure 1 , 2 As shown in Figure 3, the inner roller 223 assembly includes an inner roller shaft 222 and an inner roller 223, the two ends of the inner roller shaft 222 are respectively fixedly connected to the two mounting plates 221, the inner roller 223 is sleeved on the inner roller shaft 222 and can rotate around the inner roller shaft 222; the two outer roller 225 assemblies are located on both sides of the second gap 227, the outer roller 225 assembly includes an outer roller shaft 224 and an outer roller 225, the first end of the outer roller shaft 224 is fixedly connected to the mounting plate 221, and the second end extends in the direction of the second gap 227, the outer roller 225 is sleeved on the outer roller shaft 224 and can rotate around the outer roller shaft 224; a first gap 226 is formed between the outer side wall of the outer roller 225 and the outer side wall of the inner roller 223.

[0058] Specifically, Figure 2 As described, the two mounting plates 221 are welded and fixed to the outer wall of the cage body 21, and the two ends of the inner roller shaft 222 are respectively fixed to the two mounting plates 221 by bolts. The inner roller shaft 222 and the outer roller shaft 224 are both solid metal rods, and the inner roller 223 and the outer roller 225 are both made of rubber material. The rubber material can effectively reduce the wear between the roller mechanism 22 and the guide rail assembly 12.

[0059] Further preferably, the length of the first gap 226 matches the cross-sectional length of the second guide rail 122; based on this, the roller assembly and the guide rail assembly 12 are tightly matched, limiting the movement of the roller assembly on the radial plane in the hoistway 1, and the roller assembly can only move along the track assembly in the axial direction of the hoistway 1, thereby further ensuring the smooth movement of the cage body 21 in the hoistway 1.

[0060] Preferably, the inner circumferential wall of the hoistway 1 is provided with a plurality of guide rail assemblies 12 along its circumference, and the outer circumferential wall of the cage body 21 is provided with a plurality of roller mechanisms 22 corresponding to the guide rail assemblies 12 along its circumference; in this embodiment, Figure 1 , 2As shown in Figures 4 and 5, the inner circumferential wall of the shaft 1 is provided with four guide rail assemblies 12 along its circumferential direction, and the outer circumferential wall of the cage body 21 is provided with eight roller mechanisms 22 corresponding to the guide rail assemblies 12 along its circumferential direction.

[0061] like Figures 1-12 As shown, the ship detection equipment deployment mechanism 100 provided by the present invention is applied to ocean surveys on scientific research vessels. Specifically, the shaft 1 is a hollow cylinder with a certain thickness, extending vertically upward along the bottom 31 of the ship to the main deck 32, and the frame is installed on the outer wall of the shaft 1. The cage 2 can be placed in the shaft 1 and is slidably connected to the guide rail assembly 12, and is used to carry the detection equipment and extend it downward along the shaft 1 into the water and reach a predetermined detection position; the crane 4 is used to transport the cage 2 into the shaft 1 and drive the cage 2 to rise and fall in the shaft 1, and the controller is electrically connected to the crane 4.

[0062] It should be noted that, in general, marine environment detection equipment needs to be placed in the water to work. For small-sized carrying ships, the detection equipment is retracted and deployed with invertible metal columns or hydraulic rods. For medium and large environmental monitoring ships, due to their large depth, the length of the metal column often exceeds the height of the upper building, and the hydraulic rod mechanism occupies a large deck space. Therefore, it is a more conventional method to retract and deploy underwater detection equipment through a shaft that runs through the hull 3. This method fixes the detection equipment under the cage 2, which is a simple metal frame that serves as a protective device to prevent the detection equipment from directly colliding with the shaft. The cage 2 and the detection equipment are pulled up and down in the shaft by the crane 4.

[0063] However, the existing cage 2 is mostly a simple metal pipe frame, with a lifting ring 51 generally provided on the upper part for easy connection with the crane 4, and the ocean detection equipment fixed on the lower part. There is no guide device on the inner wall of the shaft, and there is a certain gap between the cage 2 and the inner wall of the shaft. The detection equipment produces a large shaking under the influence of the ship's navigation inertia and water flow, which increases the complexity of the detection data processing and causes the cage 2 to often scrape the shaft. Because the cage 2 is in a free hanging state in the shaft, the crane 4 mainly bears the gravity of the cage 2 and the detection equipment mechanism. The shaking is further transmitted to the crane 4, which will also have an adverse effect on the crane 4.

[0064] Based on the above problems, the deployment mechanism 100 of the ship detection device provided in this application installs at least one guide rail assembly 12 along the longitudinal extension of the inner wall of the shaft 1. The crane 4 hoists the cage 2 and transports the cage 2 into the shaft 1 so that the roller mechanism 22 is inserted and matched with the guide rail assembly 12, and drives the cage 2 to extend downward into the water along the shaft 1 and reach the predetermined detection position, so that the detection instrument extends a certain distance underwater, avoiding the influence of the noise and underwater bubbles generated by the hull 3 on the measurement accuracy. The movement of the cage 2 in the shaft 1 is restricted by the guidance of the guide rail assembly 12, which can reduce the collision between the cage 2 and the shaft 1, reduce the shaking amplitude of the detection instrument, effectively ensure the detection accuracy of the detection instrument, and improve the stability and safety during the deployment process of the cage 2.

[0065] In this embodiment, as Figure 5 , 6 , 7, and 8 show, the cage body 21 is a cylindrical cage composed of several metal pipes. Specifically, the cage body 21 is surrounded by several vertical circular pipes and horizontal circular pipes to form a cylindrical cage; eight roller mechanisms 22 corresponding to the guide rail assembly 12 are arranged along the circumferential direction of the outer peripheral wall of the cage body 21. The eight roller mechanisms 22 are divided into two rows, with 4 in each row, and the 4 roller mechanisms 22 in the same row are evenly arranged along the outer peripheral wall of the cage body 21; at the same time, four guide rail assemblies 12 are arranged along the circumferential direction of the inner peripheral wall of the shaft 1 in the hull 3, and the four guide rail assemblies 12 correspond to the roller mechanisms 22. Based on this, the cage 2 is firmly clamped on the guide rail assembly 12 in the shaft 1, and the movement of the cage 2 in the radial direction in the shaft 1 is restricted, effectively avoiding the shaking of the cage 2 in the shaft 1, thereby ensuring the stable retraction and deployment of the detection instrument.

[0066] Preferably, as Figure 6 , 8 , 9 and 10 show, a fixed sleeve 6 is installed on the cage body 21. The fixed sleeve 6 extends along the length direction of the cage body 21. Specifically, the lower end of the fixed sleeve 6 is flush with the lower end of the cage body 21, and the upper end of the fixed sleeve 6 has a protruding part 62 protruding from the top of the cage body 21. A plurality of connection holes 621 are provided on the protruding part 62. Among them, the fixed sleeve 6 has a through hole 61 penetrating its upper end and lower end. Preferably, the fixed sleeve 6 is made of metal.

[0067] Furthermore, the deployment mechanism 100 of the ship detection device provided in this embodiment further includes a mounting member 5. The mounting member 5 includes a mounting rod 52 and a mounting disk 53. The mounting rod 52 passes through the through hole 61 and is connected to the fixed sleeve 6 through the connection hole 621. It can be understood that the bolt passes through the connection hole 621 to realize the detachable connection between the mounting rod 52 and the fixed sleeve 6. And because the fixed sleeve 6 is fixedly connected to the cage body 21, the connection between the mounting rod 52 and the cage body 21 is realized.

[0068] AsFigure 8 , 9 As shown in Figure 10, the upper end of the mounting rod 52 extends upward out of the through hole 61 and is fixedly connected with a lifting ring 51. The lower end of the mounting rod 52 extends downward out of the through hole 61 and is fixedly connected with a mounting disc 53. The mounting disc 53 is arranged below the cage body 21, and a plurality of mounting holes 531 for mounting detection devices are formed in the mounting disc 53. Thus, the detection instrument is fixedly installed on the mounting disc 53 through the mounting holes 531, and the crane 4 drives the cage 2 to move downward along the shaft 1, so as to lower the detection instrument into the water for detection work.

[0069] Preferably, as Figure 11 shown, the crane 4 includes a slide rail 41, a motor slide group 42 and a hook 43. The slide rail 41 is arranged above the main deck 32. Specifically, the slide rail 41 is installed on the first upper deck, and the slide rail 41 straddles directly above the shaft 1. The motor slide group 42 is movably installed on the slide rail 41 and is driven by a first driving member to move along the guide rail. The moving track of the motor slide group 42 covers the shaft 1. The hook 43 is installed on the motor slide group 42 and is driven by a second driving member to move up and down. The first driving member and the second driving member are electrically connected to the controller. Actually, the crane 4 is a standard single-girder mobile crane 4, which not only has a certain lifting capacity, can also realize the lifting and lowering of the hook 43, and can also realize the movement of the hook 43 along the slide rail 41.

[0070] Further preferably, as Figure 12 shown, a blocking plate 13 is arranged at the bottom of the shaft 1. The blocking plate 13 is used to prevent the cage 2 from slipping off from the lower end of the guide rail assembly 12. In this embodiment, the blocking plate 13 is an annular plate, and the inner diameter of the annular plate is slightly smaller than the outer diameter of the cage body 21.

[0071] It should be noted that the cage 2 provided in this embodiment is installed in a non-fixed manner. When a detection test needs to be carried out, the cage 2 is hoisted into the shaft 1 by the crane 4 and is driven by the crane 4 to move up and down in the shaft 1. When no detection test is carried out, the cage 2 is placed on the main deck 32. Thus, it is convenient to maintain, service and replace the cage 2 and the detection device.

[0072] When the embodiment of the present invention is working, the mounting member 5 is inserted into the fixed sleeve 6, and then the detection device is fixedly installed on the mounting plate 221 through the mounting holes 531. Then, the crane 4 is operated to hoist the cage 2 and move it above the shaft 1, and the roller mechanism 22 is aligned with the guide rail assembly 12 in the shaft 1. After that, the second driving member drives the hook 43 to move downward. Thus, the cage 2 moves downward along the shaft 1, and finally the detection device extends into the water and reaches the predetermined detection position, that is, the lowering action of the cage 2 is completed. It can be understood that the recovery action of the cage 2 is opposite to the lowering action process.

[0073] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
