Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering equipment, in particular to a special hydraulic quick-insert water injection conversion joint for an emergency release device. Background Art

[0002] Currently, a test platform needs to dive to a certain depth to conduct relevant tests based on test requirements. This test platform uses suction anchors deployed on the bottom of the water as anchor points to maintain relative position and depth. Due to the test tasks and test cycles, the test platform cannot be anchored in the test waters for a long time. Before each test, it must be towed to the test waters and connected to the suction anchors. The connection and release of the test platform from the suction anchors require the coordinated cooperation of a floating crane, a platform mother ship, and a speedboat.

[0003] When the test platform is connected to or released from the suction anchor, the floating crane is required to cooperate to dock the male end of the emergency release device connected to the test platform with the female end of the emergency release device placed on the U-shaped water drum and connected to the suction anchor. The speedboat operator completes the connection or release related operations of the emergency release device on the U-shaped water drum, that is, the connection or separation of the male end and the female end of the emergency release device (see the principle). Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ).

[0004] There are four locking blocks evenly distributed at the bottom of the male end of the emergency release device, which match the grooves inside the female end of the emergency release device. A hydraulic quick-connect device is installed in the middle. When water is injected into the first water inlet of the hydraulic quick-connect device and water flows out from the second water inlet, the internal valve core of the male end of the emergency release device moves, and the four locking blocks distributed at the bottom retract inside, allowing the emergency release device to be unlocked. When water is injected into the second water inlet of the hydraulic quick-connect device and water flows out from the first water inlet, the four locking blocks distributed at the bottom pop out and the emergency release device is locked (see the principle). Figure 5 ).

[0005] The existing emergency release device connection and separation operations are usually performed by two operators on a U-shaped water drum. During the process, the first water injection port of the hydraulic quick plug at the male end of the emergency release device is switched to the second water injection port through a water pressure hose connected to a water pump at one end to change the water injection direction. The hydraulic quick plug needs to be pulled out before it can be replaced. Therefore, the hydraulic quick plug needs to be inserted into the hydraulic quick plug insertion port of the male end of the emergency release device twice, and then the water pressure is used to complete the connection or separation operation between the male and female ends of the emergency release device.

[0006] Because the U-shaped drum floats on the water, it's constantly moving up and down, with limited space and time. Operators must also guard against risks like falling overboard, scratching, and being squeezed. Furthermore, the actual water surface conditions are often harsh, and the drum is subject to the influence of wind, waves, and currents. Operators must have a firm grip to ensure their safety. Using tools to disassemble and install the hydraulic quick-connect connector and the hydraulic hose connection increases the difficulty of the operation, resulting in greater difficulty and lower work efficiency. Prolonged work in harsh water conditions also increases the risk of falling overboard. Utility Model Content

[0007] In response to the work needs and existing problems in the above-mentioned background technology, the inventors have thought about and innovated, and developed an assembled, simple-structured special conversion joint. The conversion joint provides strong protection for the connection and separation operations of the male and female ends of the emergency release device, reduces the operational difficulty of connecting and separating the male and female ends of the emergency release device, improves the efficiency of the connection and separation operations of the male and female ends of the emergency release device, and further reduces the safety risks of people falling into water, scratching, being squeezed, etc. during the connection and separation operations of the male and female ends of the emergency release device.

[0008] In order to solve the above problems and achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A hydraulic quick-insert water injection conversion joint specially used for an emergency release device, comprising:

[0010] A first water injection port butt joint (1), the first water injection port butt joint (1) being connected to the first water injection port (A1) of the hydraulic quick connector (A);

[0011] A second water injection port butt joint (2), the second water injection port butt joint (2) being connected to the second water injection port (A2) of the hydraulic quick connector (A);

[0012] A ferrule direct connector (3), wherein there are two ferrule direct connectors (3), which are respectively connected to the first water injection port butt connector (1) and the second water injection port butt connector (2);

[0013] Water injection pipes (4), there are two water injection pipes (4), one end of each of which is connected to the ferrule direct connector (3);

[0014] A first water injection conversion mechanism (5), one end of which is connected to the water injection pipe (4) and the first water injection port butt joint (1), and the other end of which is connected to the connector (7), and the first water injection conversion mechanism (5) is a three-way ball valve with a sleeve;

[0015] A second water injection conversion mechanism (6), one end of which is connected to the water injection pipe (4) and the second water injection port butt joint (2), and the other end is connected to the connector (7), and the second water injection conversion mechanism (6) is a three-way ball valve with a sleeve;

[0016] A connecting piece (7), one end of which is connected to the first water injection conversion mechanism (5) through a pipeline, one end of which is connected to the second water injection conversion mechanism (6) through a pipeline, and one end of which is connected to the water supply pipe (8), and the connecting piece (7) is a ferrule tee;

[0017] A water supply pipe (8), one end of which is connected to the connector (7), and the other end of which is connected to a water supply pipe joint (9).

[0018] As a preferred solution of the present invention, the first water injection conversion mechanism (5) is connected to a first water outlet (51) and a first valve (52), and the first valve (52) is diamond-shaped as a whole, with one end being relatively slender.

[0019] As a preferred solution of the present invention, the second water injection conversion mechanism (6) is connected to a second water outlet (61) and a second valve (62), and the second valve (62) is diamond-shaped as a whole, with one end being relatively slender.

[0020] The working principle of this utility model is:

[0021] The first water injection port butt joint (1), the second water injection port butt joint (2), the ferrule direct joint (3), the water injection pipe (4), the connecting piece (7), the water supply pipe (8) and the water supply pipe joint (9) are used for conveying water from the water supply pipe (8) to the first water injection port (A1) and the second water injection port (A2) of the hydraulic quick connector (A).

[0022] The first water injection conversion mechanism (5) and the second water injection conversion mechanism (6) are used to control the flow direction of water.

[0023] Water flow direction control and emergency release device male end control:

[0024] When the lock block (B1) at the bottom of the male end of the emergency release device needs to be retracted, the first valve (52) is turned to close the first water outlet (51) of the first water injection conversion mechanism (5), i.e., the three-way ball valve of the sleeve, and the other two ports are connected; the second valve (62) is turned to close the port connecting the second water injection conversion mechanism (6), i.e., the three-way ball valve of the sleeve and the connector (7), and the other two ports are connected, so that water can be introduced through the water supply pipe (8). Furthermore, the water flows through the connector (7), the first water injection conversion mechanism (5), the water injection pipe (4) and the first water injection port joint (1) into the first water injection port (A1) of the hydraulic quick plug (A), and then flows out from the second water outlet (61) through the second water injection port (A2), the second water injection port joint (2), the water injection pipe (4) and the second water injection conversion mechanism (6). At this time, the internal valve core of the hydraulic quick plug is pushed by the water pressure, so that the lock block (B1) at the male end of the emergency release device is retracted inside.

[0025] When the locking block (B1) at the bottom of the male end of the emergency release device needs to be ejected, the first valve (52) is turned to close the port connecting the first water injection conversion mechanism (5), i.e., the three-way ball valve of the sleeve, and the connecting piece (7), and the other two ports are connected. The second valve (62) is turned to close the second water outlet (61) of the second water injection conversion mechanism (6), i.e., the three-way ball valve of the sleeve, and the other two ports are connected, so that water can be introduced through the water supply pipe (8). Further, the water flows through the connecting piece (7), the second water injection conversion mechanism (6), the water injection pipe (4) and the second water injection port joint (2) into the second water injection port (A2) of the hydraulic quick plug (A), and then flows out from the first water outlet (51) through the first water injection port (A1), the first water injection port joint (1), the water injection pipe (4) and the first water injection conversion mechanism (5). At this time, the valve core inside the hydraulic quick plug is pushed in the opposite direction by the water pressure, so that the locking block (B1) at the male end of the emergency release device is ejected.

[0026] Beneficial effects of the utility model:

[0027] 1. The utility model simplifies the operating process and improves operating efficiency: by integrating the first water injection conversion mechanism and the second water injection conversion mechanism, the hydraulic quick-plug water injection flow direction is quickly switched. There is no need to pull out the hydraulic quick plug multiple times to change the water injection port. The operator only needs to turn the valve to change the water flow direction and control the pop-up and retraction of the locking block at the bottom of the male end of the emergency release device, so that the male and female ends of the emergency release device can be quickly connected and separated, thereby simplifying the operating process and significantly improving operating efficiency.

[0028] 2. This new design adapts to harsh operating environments and reduces safety risks: Traditional water injection methods require operators to perform tedious disassembly and installation work on a U-shaped water drum in harsh water conditions. This is not only difficult to operate but also poses safety risks such as falling into the water, scratching, and being squeezed. However, this new design only requires operators to operate the valve in a relatively safe position, greatly reducing safety risks and improving operational safety.

[0029] 3. The utility model enhances connection reliability and reduces leakage: The components of the utility model are tightly connected. Compared with directly using a water pressure hose for water injection, leakage is less likely to occur, thereby ensuring the stability and reliability of the water injection operation.

[0046] There are two ferrule direct connectors 3, which are respectively connected to the first water inlet butt connector 1 and the second water inlet butt connector 2;

[0047] Water injection pipes 4, there are two water injection pipes 4, one end of each of which is connected to the ferrule direct connector 3;

[0048] A first water injection conversion mechanism 5, one end of which is connected to the water injection pipe 4 and the first water injection port butt joint 1, and the other end is connected to the connector 7. The first water injection conversion mechanism 5 is a three-way ball valve with a sleeve;

[0049] A second water injection conversion mechanism 6, one end of which is connected to the water injection pipe 4 and the second water injection port butt joint 2, and the other end is connected to the connector 7. The second water injection conversion mechanism 6 is a three-way ball valve with a sleeve;

Connector 7 is a ferrule tee;

[0051] A water supply pipe 8 , one end of which is connected to the connector 7 , and the other end of which is connected to a water supply pipe joint 9 .

[0052] Further, such as Figure 8 、 Figure 9 As shown, the first water injection conversion mechanism 5 is connected to a first water outlet 51 and a first valve 52 . The first valve 52 is diamond-shaped as a whole, with one end being relatively slender.

[0053] Furthermore, if Figure 8 、 Figure 9 As shown, the second water injection conversion mechanism 6 is connected to a second water outlet 61 and a second valve 62 . The second valve 62 is diamond-shaped as a whole, with one end being relatively slender.

[0054] In summary, the specific use process of the utility model is:

[0055] The components required for this device are prefabricated and assembled in the factory, such as Figure 9 、 Figure 10 As shown, the first water injection port butt joint 1 and the second water injection port butt joint 2 are installed on the first water injection port A1 and the second water injection port A2 of the hydraulic quick connector A, and the remaining components are assembled together.

[0056] First, when you need to complete the connection of the emergency release device, Figure 1 As shown, the floating crane D hoists the male end B of the emergency release device connected to the test platform C onto the upper part of the female end E of the emergency release device on the U-shaped water drum F.

[0057] Further, such as Figure 8 As shown, the device is connected and fixed to the first water injection port butt joint 1 and the second water injection port butt joint 2 installed on the hydraulic quick connector A, and the hydraulic hose with one end connected to the water pump is connected to the water supply pipe 8 through the water supply pipe joint 9.

[0058] Further, such as Figure 6As shown, rotate the first valve 52 and the second valve 62 so that the slender ends of the valves face leftward, and the first water outlet 51 of the first water injection conversion mechanism 5, i.e., the three-way ball valve of the ferrule, is closed, and the other two ports are connected; the second water injection conversion mechanism 6, i.e., the port connecting the three-way ball valve of the ferrule and the connector 7, is closed, and the other two ports are connected. Then, water is injected into the water supply pipe 8 through the hydraulic hose. The water flows through the connector 7, the first water injection conversion mechanism 5, the water injection pipe 4, and the first water injection port docking joint 1 into the first water injection port A1 of the hydraulic quick plug A, and then flows out from the second water outlet 61 through the second water injection port A2, the second water injection port docking joint 2, the water injection pipe 4, and the second water injection conversion mechanism 6. At this time, the internal valve core of the hydraulic quick plug is pushed by the water pressure, causing the locking block B1 at the male end of the emergency release device to retract into the interior.

[0059] Furthermore, the floating crane D hoists the male end B of the emergency release device into the female end E of the emergency release device.

[0060] Furthermore, if Figure 7 As shown, turn the first valve 52 and the second valve 62 so that the slender end of the valve is to the right, and the port connecting the first water injection conversion mechanism 5, i.e., the three-way ball valve with the sleeve and the connector 7, is closed, and the other two ports are connected; the second water outlet 61 of the second water injection conversion mechanism 6, i.e., the three-way ball valve with the sleeve is closed, and the other two ports are connected. Then, water is injected into the water supply pipe 8 through the hydraulic hose, and the water flows through the connector 7, the second water injection conversion mechanism 6, the water injection pipe 4 and the second water injection port docking joint 2 into the second water injection port A2 of the hydraulic quick plug A, and then flows out from the first water outlet 51 through the first water injection port A1, the first water injection port docking joint 1, the water injection pipe 4 and the first water injection conversion mechanism 5. At this time, the internal valve core of the hydraulic quick plug is pushed in the opposite direction by the water pressure, causing the locking block B1 of the male end of the emergency release device to pop out and lock with the female end E of the emergency release device.

[0061] Similarly, when the emergency release device needs to be released, the slender ends of the first valve 52 and the second valve 62 are turned to the left according to the above steps to complete the water injection operation, so that the locking block B1 of the male end of the emergency release device is retracted and the emergency release device is unlocked.

[0062] Finally, it should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
