Description

Technical Field

[0001] The utility model belongs to the technical field of load release, and particularly relates to an underwater load release structure. Background Art

[0002] When performing underwater or even deep - water operations, it is often necessary to drop or release the loaded objects. However, for underwater operations, in order to ensure the reliability of the release, mechanical equipment is mostly used, which requires close - range operation by staff. Since underwater operations are somewhat dangerous, with the development of intelligent manufacturing, people have begun to consider replacing it with electronic and electrical equipment.

[0003] Currently, for the above - mentioned application scenarios, some underwater load release structures have also emerged. However, in order to ensure the stability of the carried objects before release, the carrying connections are relatively complex, which increases the complexity and difficulty of the release procedure. Moreover, the release, locking, and reset procedures mostly use different control components for control, resulting in a complex structure and a large volume, which poses a great test to the underwater sealing performance. For this reason, the applicant proposed an earlier patent application with the patent number "2023219735697" and the name "Load Release Device". In this device, the load is released through a "release hook". However, the applicant found in subsequent research that since the rotation center is close to the middle, it is easy to get stuck when hanging heavy objects, resulting in the situation where it cannot rotate and thus cannot successfully release the load. Summary of the Invention

[0004] Aiming at the deficiencies of the above - mentioned prior art, the technical problem to be solved by the utility model is: how to provide an underwater load release structure to solve the problems of easy jamming and poor reliability of the existing release structure.

[0005] To solve the above - mentioned technical problem, the utility model adopts the following technical solution:

[0006] An underwater load release structure includes a sealed housing. A motor for driving a release shaft to rotate is arranged in the sealed housing. The key lies in that: a load assembly is arranged at the bottom of the sealed housing. The load assembly at least includes an unlocking member and a suspension member that are both rotatably installed. One end of the unlocking member and the release shaft have a mutually matching locking structure, and the other end of the unlocking member and the movable end of the suspension member have a mutually matching engaging structure.

[0007] In the load state, the release shaft locks one end of the unlocking member, the suspension member is clamped with the other end of the unlocking member, and the load is suspended on the suspension member.

[0008] In the load - releasing state, the release shaft is separated from the unlocking member, the unlocking member rotates and is separated from the suspension member, and the suspension member rotates to release the load.

[0009] With the above solution, the load component adopts a combination of two parts, which is easier to rotate and release the load after unlocking, can bear a greater load, is not easily stuck, and has better reliability.

[0010] Preferably, during the process of releasing the load, the unlocking member and the suspension member rotate in opposite directions. With the above solution, it is ensured that good clamping and locking can be achieved under load conditions, and after unlocking, it can rotate in the reverse direction to prevent interference and further improve reliability.

[0011] Preferably, the rotation centers of the unlocking member and the suspension member are symmetrically arranged relative to the central axis of the sealed housing, and the load bearing point of the load on the suspension member is close to the central axis of the sealed housing. With the above solution, the suspension point is offset relative to the rotation center, which can effectively avoid the rotation jamming point. On the other hand, the load can be more evenly distributed to the two rotation centers, ensuring the overall stability.

[0012] Preferably, baffles are provided on both sides of the bottom of the sealed housing corresponding to the load component, the unlocking member and the suspension member are supported on the two baffles through a support shaft, and an avoidance opening is provided on the baffle corresponding to the suspension member. With the above solution, on the one hand, the load component can be protected laterally, and through the avoidance opening, better load mounting and load limiting can be carried out.

[0013] Preferably, the rotation centers of the unlocking member and the suspension member are respectively located on both sides of the avoidance opening.

[0014] Preferably, the clamping structure includes an L-shaped notch provided at the movable end of the suspension member and a protrusion provided on the unlocking member. Under the load state, the protrusion cooperates with the L-shaped notch to limit the downward rotation of the suspension member. With the above solution, the structure is simple, easy to process and implement, and the cost is relatively low.

[0015] Preferably, the length from the protrusion to the rotation center of the unlocking member is less than the length from the position where the unlocking member cooperates with the release shaft to the rotation center of the unlocking member. With the above solution, it is ensured that the center of gravity offset distance of the unlocking member is relatively large, and it can rotate normally after unlocking, thus releasing the restriction on the suspension member.

[0016] Preferably, the suspension member has an arc-shaped structure. With the above solution, the suspension member can be clamped more tightly with the unlocking member, having better reliability.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] By using the underwater load release structure provided by the present utility model, it can effectively prevent jamming during the process of releasing the load, has better load capacity and release reliability, and at the same time can reduce the load borne by the release shaft during mounting, which is beneficial to the normal rotation and unlocking of the release shaft and prolongs its service life, etc. Description of the Drawings

[0021] Figure 3 This is a schematic structural diagram of the load component in the figure. Detailed Description of the Preferred Embodiment

[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] During specific implementation: As Figures 1 to 3 shown:

[0024] An underwater load release structure mainly includes a sealed housing 100. A motor 200 and a control circuit for controlling the rotation of a release shaft 300 are provided inside the sealed housing 100. A load component 400 is provided at the bottom of the sealed housing 100. The load component 400 at least includes an unlocking member 410 and a suspension member 420 that are both rotatably mounted. One end of the unlocking member 410 and the release shaft 300 have a matching locking structure, and the other end of the unlocking member 410 and the movable end of the suspension member 420 have a matching engaging structure.

[0025] In the loaded state, the release shaft 300 locks one end of the unlocking member 410, the suspension member 420 is clamped with the other end of the unlocking member 410, and the load is suspended on the suspension member 420.

[0026] In the load release state, the release shaft 300 is separated from the unlocking member 410, the unlocking member 410 rotates, and is separated from the suspension member 420, and the suspension member 420 rotates to release the load.

[0027] As shown in the figure, the structure of the motor 200, control circuit, and the structure in which the motor 200 controls the rotation of the release shaft 300 through a transmission structure in the present application is similar to the structure in the patent with the patent number "2023219735697" and the name "Load Release Device", so it will not be described in detail here. As described above, the key of the present application is to replace the existing release hook with the load component 400 composed of the unlocking member 410 and the suspension member 420.

[0028] During the process of releasing the load, the unlocking member 410 and the suspension member 420 rotate in opposite directions. As shown in the figure, the engaging structure includes an L-shaped notch 421 provided at the movable end of the suspension member 420, and a protrusion 411 provided on the unlocking member 410. In the loaded state, the protrusion 411 cooperates with the L-shaped notch 421 to limit the rotation of the suspension member 420.

[0029] To fully prevent the unlocking member 410 and the suspension member 420 from jamming and ensure smooth rotation, the rotation centers of the unlocking member 410 and the suspension member 420 are symmetrically arranged relative to the central axis of the sealing housing 100. The load bearing point on the suspension member 420 is close to the central axis of the sealing housing 100. Adopting this structure can also effectively improve the load-bearing capacity of the load assembly 400.

[0030] As shown in the figure, baffles 110 are provided on both sides of the bottom of the sealing housing 100 corresponding to the load assembly 400. The unlocking member 410 and the suspension member 420 are supported on the two baffles 110 through a support shaft, and an avoidance opening 111 is provided on the baffle 110 corresponding to the suspension member 420. During specific implementation, the rotation centers of the unlocking member 410 and the suspension member 420 are respectively located on both sides of the avoidance opening 111. Specifically, the baffle 110 has a first ear 112 and a second ear 113, and the first ear 112 is higher than the second ear 113. The unlocking member 410 is installed on the first ear 112, and the suspension member 420 is installed on the second ear 113.

[0031] In this embodiment, the length from the protruding portion 411 to the rotation center of the unlocking member 410 is less than the length from the position where the unlocking member 410 cooperates with the release shaft 300 to the rotation center of the unlocking member 410. As shown in the figure, the unlocking member 410 has a support arm 412, and the center of gravity of the unlocking member 410 is located on the support arm 412. A lock hole 413 is provided on the support arm 412. The lower end of the release shaft 300 has a lock block 310 adapted to the lock hole 413. The lock block 310 can rotate after passing through the lock hole 413 to lock the end of the support arm 412, and when rotated to be aligned with the lock hole 413, the restriction on the support arm 412 is released. At this time, the unlocking member 410 can rotate. As Figure 2 shown, the support arm 412 rotates downward, and the protruding portion 411 rotates upward, separating from the L-shaped notch 421, and the suspension member 420 rotates downward.

[0032] In addition, the suspension member 420 has an arc-shaped structure, and its corresponding center of the circle is on the upper side, which can relatively move the center of gravity of the suspension member 420 upward. In this way, when a load is suspended, the lateral component force exerted on the protruding portion 411 will be greater, making the engagement between the suspension member 420 and the unlocking member 410 tighter and having better reliability. When the unlocking member 410 is unlocked, the suspension member 420 can rotate downward more smoothly to release the load.

[0033] Reference Figures 1 to 3The underwater load release structure shown is used by hanging the load suspension hook on the suspension member 420. The unlocking member 410 is in a locked state, and the suspension member 420 and the unlocking member 410 are tightly clamped with each other. After the light blocking reaches the target area, the release shaft 300 can be controlled by the motor 200 to rotate, so that the locking block 310 is in the same direction as the locking hole 413, and the unlocking member 410 is unlocked. The protruding portion 411 rotates upward and separates from the L-shaped notch 421, and the suspension member 420 rotates downward, and the load slides off the suspension member 420 and is released.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the premise of this technical solution, several technical solutions with deformations and improvements should also be regarded as falling within the scope protected by this claim book.
