Description

Technical Field

[0001] The present application relates to the technical field of air tightness detection, and specifically to an air tightness detection device for ship accessories. Background Art

[0002] The hatch cover on a ship refers to the structure covering the top of the cargo hold or other compartments. As one of the key accessories on the ship, it is used to protect the cargo, equipment or the internal space of the ship from the influence of the external environment. The hatch cover is usually openable or removable to facilitate the loading and unloading of cargo and maintenance of equipment. Therefore, the airtightness of the hatch cover is directly related to the operation, safety and stability of the ship's cargo.

[0003] At present, most hatch covers are tested for air tightness in an air tightness test room before leaving the factory. They will only leave the factory after passing the air tightness test. However, considering that ships may be corroded by humid and high-salt airflow during long-term voyages at sea, hatch covers may be corroded and produce gaps, resulting in air tightness problems and affecting the normal and safe storage of cargo. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose an air tightness detection device for ship accessories to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides an air tightness detection device for ship accessories, including a foam cylinder, the bottom of which is fixedly connected to a grip rod, the top of which is provided with a valve tube, one end of the foam cylinder is fixedly connected to a connecting frame, the output end of the connecting frame is fixedly connected to a coating tube, a liquid pushing mechanism is provided inside the foam cylinder, and a sealing mechanism is provided on the connecting frame.

[0006] Preferably, the liquid pushing mechanism includes an inner-cylinder rod movably connected to the inside of the foam cylinder, a piston is provided at one end of the inner-cylinder rod close to the foam cylinder, and the outer surface of the piston is slidably connected to the inner surface of the foam cylinder. The liquid pushing mechanism can push the foam agent in the foam cylinder into the application tube through the connecting frame, and finally the foam agent is applied to the suspicious gap on the cabin cover to detect the air tightness.

[0007] Preferably, a spring is movably sleeved on the periphery of the inner-cylinder rod, and a rod head button is provided at one end of the inner-cylinder rod away from the piston.

[0008] Preferably, the sealing mechanism includes a connecting cavity opened inside the connecting frame, a bottom shaft is fixedly penetrated through the inner side of the connecting frame, and a double swing bar is rotatably connected to the outer surface of the bottom shaft. The sealing mechanism can block the foam agent in the foam cylinder to prevent the foam agent from leaking out during the application interval.

[0009] Preferably, one end of the double swing bar away from the bar bottom axis is rotatably connected to the bar top axis, the outer surface of the bar top axis is rotatably connected to the pressure frame, and the inner surface of the pressure frame is rotatably connected to the frame inner axis.

[0010] Preferably, the outer surface of the inner shaft of the frame is rotatably connected to a sealing stick, the outer surface of the sealing stick is slidably connected to the inner surface of the connecting frame, and a pressure handle is provided at one end of the pressure frame away from the double swing bar. The sealing stick can block the connecting cavity in the connecting frame to prevent the foaming agent from flowing.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The ship accessories air tightness detection equipment can apply the foam agent to the suspected gaps of the hatch cover through the liquid pushing mechanism and the sealing mechanism. If gas or liquid leaks through these areas, the foam agent will form bubbles at the leakage point, thereby providing a clear visible signal indicating that there is a leak, thereby achieving fast and clear air tightness detection.

[0013] 2. When testing another suspected gap in the hatch cover, the ship accessories air tightness testing equipment can hold the pressure handle and use the sealing mechanism to re-seal the connecting cavity with the sealing stick to prevent the foam liquid from leaking out, thereby achieving the effect of performing air tightness testing on different positions of the hatch cover through manual operation of the equipment at the appropriate time.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A ship accessories air tightness detection device includes a foam cylinder 1, a grip rod 2 is fixedly connected to the bottom of the foam cylinder 1, a valve tube 3 is arranged on the top of the foam cylinder 1, one end of the foam cylinder 1 is fixedly connected to a connecting frame 4, an output end of the connecting frame 4 is fixedly connected to a smear tube 5, a liquid pushing mechanism is arranged inside the foam cylinder 1, and a sealing mechanism is arranged on the connecting frame 4.

[0021] Through the above technical solution, the device can inject foaming agent into the foam tube 1 through the valve tube 3 when in use, and the foaming agent can be applied to the suspicious gaps on the surface of the hatch cover at an appropriate time through the liquid pushing mechanism and the sealing mechanism to detect the air tightness.

[0022] Specifically, the liquid pushing mechanism includes an inner rod 6 movably connected to the inside of the foam tube 1 , a piston 7 is provided at one end of the inner rod 6 close to the foam tube 1 , and the outer surface of the piston 7 is slidably connected to the inner surface of the foam tube 1 .

[0023] Through the above technical solution, the piston 7 can push the foaming agent during the sliding displacement along the inner wall of the foam tube 1.

[0024] Specifically, a spring 8 is movably sleeved on the periphery of the inner rod 6 , and a rod head button 9 is provided at one end of the inner rod 6 away from the piston 7 .

[0025] Through the above technical solution, under the elastic action of the spring 8, the piston 7 can be pushed forward, thereby linking the rod 6 in the cylinder to move synchronously.

[0026] Specifically, the blocking mechanism includes a connecting cavity 10 opened inside the connecting frame 4 , a bar bottom shaft 11 is fixedly penetrated through the inner side of the connecting frame 4 , and a double swing bar 12 is rotatably connected to the outer surface of the bar bottom shaft 11 .

[0027] Through the above technical solution,

[0028] Specifically, one end of the double swing bar 12 away from the bar bottom axis 11 is rotatably connected to the bar top axis 13 , the outer surface of the bar top axis 13 is rotatably connected to the pressure frame 14 , and the inner surface of the pressure frame 14 is rotatably connected to the frame inner axis 15 .

[0029] Through the above technical solution, the upward pulling pressure frame 14 can pull up the sealing glue rod 16 through the inner shaft 15 of the frame, so that the sealing glue rod 16 no longer blocks the connecting cavity 10.

[0030] Specifically, the outer surface of the inner shaft 15 of the frame is rotatably connected with a sealing glue stick 16 , and the outer surface of the sealing glue stick 16 is slidably connected with the inner surface of the connecting frame 4 . A pressure handle 17 is provided at one end of the pressure frame 14 away from the double swing bar 12 .

[0031] Through the above technical solution, when the sealing glue stick 16 is basically pushed into the connecting frame 4, the connecting cavity 10 can be blocked, so that the foaming agent cannot be pushed from the foam tube 1 through the connecting frame 4 to the application tube 5.

[0032] Working principle: When the device is used to test the air tightness of the hatch cover of a ship, the rod head button 9 is first pulled outward, and the piston 7 is made to slide toward the rod head button 9 through the rod 6 inside the tube. The spring 8 will be squeezed until the piston 7 is located in the internal area of ​​the foam tube 1 between the valve tube 3 and the rod head button 9. The valve tube 3 can then be opened to inject the foam agent into the foam tube 1. At this time, the rod head button 9 is released. Under the elastic reset action of the spring 8, the piston 7 can slide along the inner wall of the foam tube 1 toward the application tube 5 and push the foam agent at the same time. Since the sealing stick 16 blocks the connecting cavity 10 in the connecting frame 4 at this time, the foam agent cannot pass through the connecting frame 4. Then, the grip rod 2 is manually held to adjust the angle of the foam tube 1. After the inclined end of the application tube 5 is pressed against the suspected gap on the surface of the hatch cover, it can be pulled upward. The dynamic pressure handle 17 causes the pressure frame 14 to rotate along the top axis 13 of the bar, and at the same time, the sealing stick 16 is lifted up through the inner axis 15 of the frame, so that the sealing stick 16 is gradually pulled out from the connecting frame 4. During this process, the double swing bar 12 will rotate along the bottom axis 11 of the bar, and at the same time, the sealing stick 16 will gradually break away from the connecting cavity 10 and no longer block it, and the piston 7 can continue to slide forward, pushing the foaming agent into the application tube 5 through the connecting cavity 10 in the connecting frame 4, and finally applying it to the suspected gaps in the hatch cover. If gas or liquid leaks through these areas, the foaming agent will form bubbles at the leakage point, thereby providing a clear visible signal indicating that there is a leak, thereby achieving rapid and clear airtightness detection. The entire detection process is simple and fast, without complicated operations, and is easy to promote.
