[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, a deepwater pre-commissioning receiving and sending cylinder flip frame according to an embodiment of the present invention comprises a base 10, a flip seat 20 arranged on the base 10, a support seat 30 and at least one support frame 40. The base 10 serves as a supporting base for the entire flip frame, and the flip seat 20 is used on the base 10 to connect with a connector 110 installed on one end of the receiving and sending cylinder 100. The support seat 30 is spaced apart from the flip seat 20 on the base 10 and is used to support and position the other end of the receiving and sending cylinder 100 thereon. The support frame 40 is located between the flip seat 20 and the support seat 30 on the base 10 and is used to support the bottom of the receiving and sending cylinder 100.

[0030] A guide cylinder 21 is provided on the first surface of the flip seat 20, which is used to cooperate with the connector 110 on the sending and receiving cylinder 100, so that the sending and receiving cylinder 100 can be positioned on the first surface of the flip seat 20 and fixed relative to the flip seat 20. The flip seat 20 can rotate back and forth between a first position and a second position relative to the base 10. In the first position, the flip seat 20 is vertical relative to the base 10, the guide cylinder 21 faces the support seat 30, and the sending and receiving cylinder 100 is horizontally arranged between the flip seat 20 and the support seat 30. Figure 2 In the second position, the flip seat 20 is parallel to the base 10 and with the first surface facing upward, the ball receiving cylinder 100 is erected on the flip seat 20 through the connector 110 and the guide cylinder 21, as shown Figure 3 shown.

[0031] Specifically, the base 10 may include a support frame 11 and an anti-sinking plate 12 disposed at the bottom of the support frame 11. The support frame 11 is mainly formed by welding H-shaped steel and steel plates, etc., and has reliable structural strength, ensuring the safety of the turnover frame under transportation and hoisting conditions.

[0032] The anti-sinking plate 12 is welded to the bottom of the support frame 11, and mainly bears the pressure to ensure that the turning frame does not sink into the seabed when it enters the water. The anti-sinking plate 12 is distributed with a plurality of water-permeable holes 13, which can pass water and reduce the area of ​​the anti-sinking plate 12, and is used to reduce the impact area when the turning frame is hoisted into the water, thereby reducing the impact force of the waves on the turning frame and preventing the rope from loosening when entering the water.

[0033] The flip seat 20 is arranged on the base 10 and can rotate relative to the base 10, so as to realize the flipping of the sending and receiving ball cylinder 100, so as to meet the transportation horizontal state and the operation vertical state of the sending and receiving ball cylinder 100. The flip seat 20 may include a frame and a steel plate formed by welding of steel sections, the steel plate is fixed to at least one side of the frame, wherein the surface of one steel plate forms a first surface, and the guide cylinder 21 is fixed to the first surface by welding or the like. The connector 110 on the sending and receiving ball cylinder 100 is inserted into the guide cylinder 21 and positioned on the flip seat 20, so as to realize the fixing of the sending and receiving ball cylinder 100 on the flip seat 20.

[0034] Corresponding to the flip seat 20, two opposite first support rods 14 are provided on the base 10, and the first support rods 14 can be welded on the edge of the base 10. The opposite ends of the flip seat 20 are mounted on the first support rods 14 through the rotating shaft 221 and can rotate relative to the first support rods 14. The rotation angle of the flip seat 20 can be 0-90°, 0-180° or 0-360°, etc., and the rotation angle between the first position and the second position is 0-90°. An oblique support rod is also connected between the first support rod 14 and the base 10 to stabilize the first support rod 14.

[0035] The base 10 is also provided with a second support rod 15, which is located on a side of the flip seat 20 away from the support seat 30 and between the two first support rods 14. A locking assembly 16 is provided on the top of the second support rod 15, and a locking portion 22 cooperating with the locking assembly 16 is provided on one side of the flip seat 20.

[0036] When the flip seat 20 is in the second position, the locking portion 22 is located at the top of the second support rod 15 and is locked and connected through the locking assembly 16, thereby keeping the flip seat 20 in the second position (i.e., Figure 3 The parallel base 10 shown in the figure ensures the firmness and reliability of the flip seat 20 in the second position.

[0037] The locking assembly 16 may include a fixed shaft seat and a fixed pin that can be laterally inserted into the fixed shaft seat. The locking portion 22 includes a locking plate that can be matched with the fixed shaft seat, and the locking plate is provided with a locking hole that is compatible with the fixed pin. When the flip seat 20 rotates to the second position, after the locking portion 22 is matched with the fixed shaft seat, the operator or the underwater robot can insert the fixed pin into the locking portion 22 and the fixed shaft seat, and lock the locking portion 22, thereby positioning the flip seat 20. In order to facilitate the operation of the underwater robot, a handle can be welded on the fixed pin.

[0038] An oblique support rod is also connected between the second support rod 15 and the base 10 to stabilize the second support rod 15 .

[0039] The support seat 30 is spaced apart from the flip seat 20 on the base 10, and the distance between them is set according to the length of the sending and receiving cylinder 100. When the sending and receiving cylinder 100 is horizontally placed on the flip frame, the connector 110 at one end of the sending and receiving cylinder 100 cooperates with the guide cylinder 21 on the flip seat 20 and is relatively fixed, and the other end is placed on the support seat 30 and positioned.

[0040] In this embodiment, the support seat 30 includes a third support rod 31 erected on the base 10, and an openable and closable pipe clamp 32 disposed on the top of the third support rod 31. The openable and closable setting of the pipe clamp 32 enables it to fit the outer periphery of the end of the sending and receiving ball cylinder 100, locking it on the support seat 30. In order to facilitate the underwater robot to operate the opening and closing of the pipe clamp 32, the pipe clamp 32 is opened and closed and locked by a fixed pin shaft provided with a handle.

[0041] An oblique support rod is also connected between the third support rod 31 and the base 10 to stabilize the third support rod 31 .

[0042] Since the ball receiving and sending cylinder 100 has a certain length, when it is in a horizontal state on the flip frame, in addition to the cooperation between the two ends and the flip seat 20 and the support seat 30, the middle part needs to be supported by the support frame 40 to make it stable. The number of support frames 40 can be set as needed, and can be arranged at one or more intervals.

[0043] The support frame 40 may include two support rods 41 disposed on the base 10 at intervals and opposite to each other, and a cross bar 42 transversely connected between the two support rods 41. The upper ends of the two support rods 41 protrude upward relative to the cross bar 42, and the sending and receiving cylinder is mainly supported on the cross bar 42. The upper ends of the support rods 41 restrict the sending and receiving cylinder 100 on the cross bar 42 to prevent it from falling out of the support frame 40.

[0044] Preferably, the upper end of the support rod 41 is bent in a direction away from the cross rod 42 , so that a guide opening is formed at the top of the support frame 40 , which guides the placement of the sending and receiving ball barrel 100 into the support frame 40 .

[0045] Furthermore, the deepwater pre-debugging receiving and launching tube flip frame of the present invention also includes a lifting ear 50 arranged on the base 10, which plays a role in lifting the flip frame. During lifting, the lifting buckle is inserted into the lifting ear hole of the lifting ear 50.

[0046] In this embodiment, Figure 1 As shown, the base 10 is rectangular as a whole, and at least four lifting ears 50 are provided and distributed at the diagonals of the base 10 .

[0047] Combination Figure 1-3 When the deep-water pre-debugging transmitting and receiving ball cylinder flipping frame of the present invention is used, the transmitting and receiving ball cylinder 100 is horizontally placed on the base 10 and supported on the support frame 40. One end of the transmitting and receiving ball cylinder 100 provided with a connector 110 cooperates with the guide cylinder 21 of the flip seat 20 for positioning, and can further be bundled and reinforced with a cable; the other end of the transmitting and receiving ball cylinder 100 is placed on the support seat 30 and fixed by a pipe clamp 32. After completion, the transmitting and receiving ball cylinder 100 can be transported, hoisted, put into water, and other operations.

[0048] When the sending and receiving ball cylinder 100 is connected underwater, the pipe clamp 32 can be operated by an underwater robot to release the fixation of one end of the sending and receiving ball cylinder 100 on the support seat 30; the sending and receiving ball cylinder 100 is flipped to a vertical state, and at the same time, the flip seat 20 is driven to flip relative to the base 10 to be parallel to the base 10, and the locking part 22 on the flip seat 20 cooperates with the locking assembly 16 to lock and fix and maintain the horizontal state of the flip seat 20, thereby ensuring the stability of the vertical state of the sending and receiving ball cylinder 100.

[0049] After the sending and receiving ball cylinder 100 is flipped to be vertical, the connector 110 can be detached therefrom to release the fixing of the sending and receiving ball cylinder 100 on the flip seat 20, so as to facilitate the subsequent lifting of the sending and receiving ball cylinder 100.
