Description

Technical Field

[0001] This utility model relates to the field of ship pipeline connection technology, specifically to a locking device for ship dock pipelines. Background Technology

[0002] Marine clean-up vessels are special vessels used for marine environmental protection, pollution prevention and control and ecological restoration. Their core function revolves around reducing the negative impact of human activities on the ocean. Among them, oily wastewater receiving vessels are the main ones. Their role is to receive oily wastewater, domestic sewage and hazardous waste generated by ships or offshore buildings at sea, and transport them back to the dock for professional treatment to achieve resource utilization.

[0003] When the cleaning vessel berths at the dock, the method for transferring oily wastewater is to connect the vessel's oil sludge pipe to an external transfer pipe using screws. However, due to the large number of cleaning vessels berthing at the dock and the frequent disassembly and reassembly of the screws at the oil sludge pipe connection, the operation is repetitive and tedious. Problems such as missing screws and stripped screws also frequently occur, further complicating the operation. In addition, due to the lack of suitable tools or screws, some screws at the oil sludge pipe connection may not be tightened properly, leading to problems such as pollutant leakage during the operation. Utility Model Content

[0004] To address the problems mentioned in the background section, a locking device for pipelines in ship docks is proposed. The technical solution adopted by this utility model is as follows:

[0005] A locking device for a ship dock pipeline, applied at the connection between a transfer pipe and an oil sludge pipe, includes a locking assembly. The locking assembly includes two plug-in parts for connecting the transfer pipe and the oil sludge pipe. A fixing bolt is fixedly installed at one end of each plug-in part, and a movable bolt is movably installed at the other end of each plug-in part away from the fixing bolt. The transfer pipe and the oil sludge pipe are fixedly connected by the cooperation of the fixing bolt and the movable bolt.

[0006] Preferably, one end of each of the two plug-in portions is fixedly connected to one side of the handle component with the fixing bolt.

[0007] Preferably, a combination part is fixedly connected between the fixing bolts on the two plug-in parts.

[0008] Preferably, the plug portion is provided with a thread corresponding to the movable bolt, and the movable bolt is movably installed on the plug portion based on the thread.

[0009] Preferably, a first fixing member is fixedly installed on the outer periphery of the transfer pipe near the oil sludge pipe, and a second fixing member is fixedly installed on the outer periphery of the oil sludge pipe near the transfer pipe. The transfer pipe abuts against the oil sludge pipe, and the first fixing member and the second fixing member abut against one end of the fixing bolt and the assembly and the movable bolt, respectively.

[0010] The advantages of this utility model of a locking device for pipelines in ship docks are as follows:

[0011] 1. By combining and installing two plug parts on the handle, the two plug parts can be used simultaneously, which can not only solve the problem of inconsistent screws, but also avoid pollution and safety hazards, and increase efficiency and convenience.

[0012] 2. By connecting two fixing bolts through the assembly, the rigidity between the plug-in parts is enhanced. During use, the assembly abuts against the transfer pipe or oil pipe. As long as the fixing bolt and movable bolt on a single plug-in part are in the assembled and tightened state, it can also ensure that the fixing holes on the entire locking device have a tightening effect. This solves the problem that when a bolt is not tightened or even falls off when a single fixing hole is used for fixing connection, the tightening force at the abutment of the transfer pipe and the oil pipe is insufficient, resulting in gaps and oil leakage.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figs. 1-3As shown, a locking device for a ship dock pipeline is applied at the connection between a transfer pipe 1 and an oil sludge pipe 2. The device includes a locking assembly 5, which includes two insertion parts 504 for connecting the transfer pipe 1 and the oil sludge pipe 2. A fixing bolt 502 is fixedly installed at one end of each insertion part 504, and a movable bolt 505 is movably installed at the other end of each insertion part 504 away from the fixing bolt 502. The transfer pipe 1 and the oil sludge pipe 2 are fixedly connected by the cooperation of the fixing bolt 502 and the movable bolt 505.

[0019] In this embodiment, the transfer pipe 1 and the oily waste pipe 2 are provided with several corresponding fixing holes. The plug part 504 is inserted into the fixing hole. By moving the movable bolt 505 closer to the fixing bolt 502, the transfer pipe 1 and the oily waste pipe 2 are sealed and abutted. The distance between the movable bolt 505 and the fixing bolt 502 is fixed by fixing the movable bolt 505, ensuring that the transfer pipe 1 and the oily waste pipe 2 are kept in close communication, thereby ensuring that the transfer of oily wastewater is carried out smoothly.

[0020] In one embodiment, one end of each of the two plug-in portions 504 is fixedly connected to one side of the handle 501 by a fixing bolt 502.

[0021] In this embodiment, two plug-in parts 504 are fixedly connected to the handle 501 to form an assembly, and the distance between the two plug-in parts 504 corresponds to the distance between the two fixing holes on the transfer pipe 1 and the oil pipe 2. This allows the two plug-in parts 504 to be quickly plugged into the fixing holes based on the handle 501, which improves work efficiency. At the same time, the assembled assembly is larger in size and easier to spot with the naked eye, avoiding the difficulty in finding the plug-in parts 504 if they are lost.

[0022] In one embodiment, a combination portion 503 is fixedly connected between the fixing bolts 502 on the two plug portions 504.

[0023] In this embodiment, two fixing bolts 502 are fixedly connected by the assembly part 503, which enhances the rigidity between the plug-in parts 504. When in use, the assembly part 503 abuts against the transfer pipe 1 or the oil pipe 2. As long as the fixing bolt 502 and the movable bolt 505 on a single plug-in part 504 are in the assembled and tightened state, it can also ensure that the fixing holes on the entire locking device have a tightening effect. This solves the problem that when a bolt is not tightened or even falls off when a single fixing hole is fixedly connected with a corresponding bolt, the tightening force at the abutment of the transfer pipe 1 and the oil pipe 2 is insufficient, resulting in gaps and oil leakage.

[0024] In one embodiment, the plug portion 504 is provided with a thread corresponding to the movable bolt 505, and the movable bolt 505 is movably mounted on the plug portion 504 based on the thread.

[0025] In this embodiment, by adjusting the distance between the movable bolt 505 and the fixed bolt 502 of the threaded connection, it is ensured that the transfer pipe 1 and the oil pipe 2 are in a completely tight contact state and have a certain fastening force.

[0026] In one embodiment, a first fixing member 3 is fixedly installed on the outer periphery of the transfer pipe 1 near the oil sludge pipe 2, and a second fixing member 4 is fixedly installed on the outer periphery of the oil sludge pipe 2 near the transfer pipe 1. The transfer pipe 1 abuts against the oil sludge pipe 2, and the first fixing member 3 and the second fixing member 4 abut against one end of the fixing bolt 502 and the assembly part 503 and the movable bolt 505, respectively.

[0027] In this embodiment, the first fixing member 3 and the second fixing member 4 are fixed by means of fixing bolt 502 and movable bolt 505, so as to fix the transfer pipe 1 and the oil pipe 2 and make the pressure at the contact point of the two the same, so as to avoid oil and sewage leakage.

[0028] The specific implementation method of the locking device for pipelines at ship docks according to this utility model is as follows:

[0029] First, connect the ends of the transfer pipe 1 and the oil pipe 2. Manually hold the handle 501 and insert the two plug parts 504 into the corresponding fixing holes until the fixing bolt 502 and the assembly part 503 are fully engaged with the transfer pipe 1 or the oil pipe 2. Then, install the movable bolt 505 on the end of the plug part 504 away from the fixing bolt 502 using a threaded connection. Rotate the movable bolt 505 until it engages with the transfer pipe 1 or the oil pipe 2. This clamps the first fixing part 3 and the second fixing part 4 with the fixing bolt 502 and the movable bolt 505, ensuring that the ends of the transfer pipe 1 and the oil pipe 2 are fully engaged and have a certain tightening force. This ensures that the fixing holes on the entire locking device have a tightening effect, avoiding the problem of insufficient tightening force at the connection between the transfer pipe 1 and the oil pipe 2 when a bolt is not tightened or even falls off, which can lead to gaps and oil leakage, as is the case with traditional single fixing holes using corresponding bolts. After the oily wastewater transfer operation is completed, the movable bolt 505 is turned in the opposite direction and unscrewed to release the plug-in installation method of the plug part 504. The movable bolt 505 is then reinstalled on the plug part 504 for device recovery, avoiding the problem of the movable bolt 505 or the plug part 504 falling off and being difficult to find.

[0030] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
