Description

Technical Field

[0001] The invention relates to the technical field of diving chambers, in particular to a spherical diving chamber. Background Art

[0002] An underwater vehicle is a navigation body that travels underwater, also known as a submersible. It is mostly used in the exploration of marine resources at great depths and in a wide range and in the field of military operations. It is characterized by large size, high navigation speed, and low resistance. The submersible cabin has a variety of styles, such as a ship-shaped diving cabin, a spherical diving cabin, etc. Among them, the spherical diving cabin has a wide range of uses and can be used for underwater sightseeing, underwater exploration, etc. However, due to the unique shape of the spherical diving cabin, it is not convenient to fix the cabin when it is transported and maintained after use. When transferring the spherical cabin, most of the existing methods are to lift and rotate it through a lifting device. The spherical diving capsule needs to be moved, so that a special lifting device is needed in actual use, which makes it more cumbersome to use. When the diving capsule needs to be maintained, it needs to be maintained indoors, and the spaces of different maintenance rooms are different. When the spherical diving capsule is transferred in some rooms with smaller spaces, it is inconvenient to use the lifting device due to space limitations, making it difficult to move the diving capsule. Moreover, when the spherical diving capsule is lifted and transferred by the lifting device, the diving capsule will swing in the air. When it is lifted in the room, it is easy for the diving capsule to collide with external objects, which makes it easy to damage the diving capsule.

The fixing frame is fixedly provided with a At the bottom of the placement plate 13, when in use, when the diving chamber body 11 is fixedly arranged on the upper end of the placement plate 13, when the diving chamber body 11 needs to be moved, the motor 34 is started, and the output end of the motor 34 drives the worm 33 to rotate, and the worm 33 meshes and rotates with the worm wheel 32, so that the worm wheel 32 drives the bidirectional screw 31 to rotate, and under the action of the thread, the two threaded connecting blocks 30 move along the axis direction of the bidirectional screw 31, and the moving directions are opposite. When the threaded connecting block 30 moves, the connecting slider 27 is driven to slide on the first guide slider 28 through the two third connecting rods 29, and the connecting slider 27 During sliding, several rotating legs 23 are driven to rotate simultaneously through the second connecting rod 26 and the connecting shaft 25, so that the rotating legs 23 are unfolded.

The spring telescopic rods 38 are all fixedly arranged inside the mounting tube 39, and a second guide slide rod 42 is slidably provided on the mounting tube 39, and support plates are fixedly provided at both ends of the second guide slide rod 42, and the support plates are all fixedly provided on one side of the rotating leg 23. A return spring 43 is provided between the mounting tube 39 and the upper end of a support plate, and a push assembly for driving the movement of a plurality of mounting tubes 39 is provided at the bottom end of the placement plate 13. When the diving chamber body 11 is moved and the rotating legs 23 need to be stored, the plurality of mounting tubes 39 are pushed by the push assembly to move, so that the mounting tubes 39 move along the length direction of the second guide slide bar 42. The mounting tubes 39 move while driving the friction rods 37 to move. The friction rods 37 are in close contact with the correction wheel 36, so that the correction wheel 36 is driven to rotate. When the correction wheel 36 rotates, the roller 24 is driven to rotate through the second fixed shaft and the third fixed shaft, so that the axis of the roller 24 is parallel to the axis of the connecting shaft 25. When the plane notch of the correction wheel 36 is in close contact with the friction rod 37, Under the action of the spring telescopic rod 38, one side of the friction rod 37 is in close contact with several rotating rollers. When the friction rod 37 continues to move and returns to the initial position, the correction wheel 36 no longer rotates, thereby completing the correction of the position of the roller 24, making it convenient to store the rotating leg 23. When the roller 24 is in use and the horizontal working angle of the roller 24 is changed, the roller 24 cooperates with the second conical friction wheel through the first conical friction wheel 35 to make the correction wheel 36 rotate.

A ball is provided on one end of the push rod 40, and a guide plate 41 is tightly attached to one end of the push rod 40. Several guide plates 41 are fixedly arranged on the bottom end of the placement plate 13. When in use, after the position of the roller 24 is corrected, under the action of the spring telescopic rod 38, one side of the friction rod 37 contacts with several rotating rollers, so that the friction rod 37 is separated from the inside of the mounting tube 39. Subsequently, when the rotating leg 23 is stored, one end of the push rod 40 is tightly attached to one side of the guide plate 41, so that the position of the friction rod 37 is fixed, thereby preventing the roller 24 from rotating during the storage process of the rotating leg 23 or when the placement plate 13 is used after storage.

[0038] Example 2

[0039] The difference from Example 1 is that: the bottom end of the fixed leg 14 is provided with a mounting through hole, and the mounting through hole is provided with an adjusting leg 46. One end of the adjusting leg 46 is fixed with a supporting circular plate, and one end of the adjusting leg 46 is provided with an external thread. The adjusting leg 46 is provided with an adjusting turn block 47 in thread cooperation. The adjusting turn block 47 is rotatably arranged at one end of the fixed leg 14, and the cross-section of the adjusting turn block 47 is a regular hexagon. When in use, when it is necessary to adjust the working height of the placement plate 13, by rotating the adjusting turn block 47, under the action of the thread, the adjusting leg 46 is moved along the axial direction of the fixed leg 14, thereby adjusting the working height of the placement plate 13.

[0040] A first friction plate is fixedly provided on the adjusting rotary block 47, a second friction plate is tightly provided on the upper end of the first friction plate, the second friction plate is rotatably provided on one end of a stop screw 48, the stop screw 48 is rotatably provided in a threaded hole on the upper end of a third rotating plate, the third rotating plate is fixedly provided on the fixed leg 14. When in use, after the working height of the placement plate 13 is adjusted, the stop screw 48 is rotated, and under the action of the thread, the stop screw 48 drives the second friction plate to move, and when the first friction plate is tightly attached to the second friction plate, the adjusting rotary block 47 is fixed.

[0041] The above embodiment discloses a spherical diving chamber, wherein when the diving chamber body 11 needs to be transferred, the diving chamber body 11 is lifted to the upper end of the placement plate 13 by an external lifting component, and the supporting frame 12 is located on the inner side of the limiting ring 15, and then the first electric push rod 21 is started, and the output end of the first electric push rod 21 drives the rack 20 to move. Since the gear 19 and the rack 20 are meshed with each other, the gear 19 drives the rotating disk 18 to rotate through the first fixed shaft. While the rotating disk 18 rotates, the limiting slide bar 16 is pushed to slide through a plurality of first connecting rods 17, so that one end of the limiting slide bar 16 is inserted into the limiting groove. At this time, the bottom end of the limiting slide bar 16 is tightly attached to the supporting frame 12, so that the diving chamber body 11 is fixedly connected to the placement plate 13. When the diving chamber body 11 needs to be moved , start the motor 34, the output end of the motor 34 drives the worm 33 to rotate, the worm 33 meshes and rotates with the worm wheel 32, so that the worm wheel 32 drives the bidirectional screw 31 to rotate, and under the action of the thread, the two threaded connection blocks 30 move along the axis direction of the bidirectional screw 31, and the movement directions are opposite. When the threaded connection block 30 moves, the two third connecting rods 29 drive the connecting slider 27 to slide on the first guide slider 28. When the connecting slider 27 slides, the second connecting rod 26 and the connecting shaft 25 drive several rotating legs 23 to rotate at the same time, so that the rotating legs 23 are unfolded. When the length direction of the rotating legs 23 is perpendicular to the bottom end of the placement plate 13, the roller 24 contacts the ground, and the adjustment leg 46 is away from the ground. Then, the placement plate 13 is pushed to move, so that the diving tank body 11 is transferred;

[0042] When it is necessary to fix the placement plate 13, several second electric push rods 45 are started at the same time. The output end of the second electric push rod 45 pushes the push rod 44 to move. The push rod 44 pushes the mounting tube 39 to move through the fixing rod, so that the mounting tube 39 moves along the length direction of the second guide slide rod 42. When the mounting tube 39 moves, the friction rod 37 is driven to move. The friction rod 37 is in close contact with the correction wheel 36, so that the correction wheel 36 is driven to rotate. When the correction wheel 36 rotates, the roller 24 is driven to rotate through the second fixed shaft and the third fixed shaft, so that the axis of the roller 24 is parallel to the axis of the connecting shaft 25. When the plane notch of the correction wheel 36 is in close contact with the friction rod 37, the spring is stretched. Under the action of the retracting rod 38, one side of the friction rod 37 is in close contact with several rotating rollers. When the friction rod 37 continues to move and returns to the initial position, the correction wheel 36 no longer rotates, thereby completing the correction of the position of the roller 24, so that the output end of the roller 24 drives the bidirectional screw 31 to rotate in the opposite direction, so that the rotating leg 23 is stored. At the same time, during the rotation process, one end of the push rod 40 is in close contact with one side of the guide plate 41, so that the position of the friction rod 37 is fixed, preventing the roller 24 from rotating when the rotating leg 23 is being stored or the placement plate 13 is used after storage, and then the leg 46 is adjusted to contact the ground, thereby fixing the placement plate 13.
