Technical Field

[0001] The utility model relates to the technical field of ship filling equipment, and more specifically, to an anti-drip device for ship filling. Background Art

[0002] During the use of existing ship filling equipment, when filling fuel into a ship, a flange connection is usually adopted. When the ship is docked at a wharf or sailing on the sea, the impact of water flow often causes the ship to shake and is not very stable. This leads to an unstable filling state during filling, which may cause the fuel to leak and drip onto the ship's hull, affecting the filling effect. Moreover, if too much fuel drips, it will not only cause waste but also may cause safety accidents. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an anti-drip device for ship filling.

[0008] Further, the first sealing airbag is glued in the first annular groove, and a first control valve is provided on the first inflation port.

[0009] Further, the outer sealing mechanism includes a sleeve pipe fixedly connected to the lower surface of the limiting ring. A sleeve ring for fitting on the outer pipe surface of the ship filling pipe is fixedly connected to the end of the inner side surface of the sleeve pipe far from the limiting ring. A second annular groove is provided on the inner ring surface of the sleeve ring, and a second sealing airbag is connected in the second annular groove.

[0010] Further, the second air inlet pipe of the second sealing airbag is fixedly sealed in the second pipe through hole of the sleeve pipe and penetrates out above the limiting ring. A second control valve is provided on the second air inlet pipe.

[0011] Further, a drip liquid collection area is formed among the limiting ring, the sleeve pipe, the sleeve ring and the liquid guide pipe.

DETAILED DESCRIPTION

[0025] In order to clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0027] See also Figures 1-5 The utility model provides a technical solution of a drip-proof device for ship filling, comprising: a liquid guide tube 1 for inserting into a ship filling pipe; the liquid guide tube 1 has a liquid inlet and a liquid outlet, and a first annular groove is provided on the outer tube surface of the liquid guide tube 1 near the liquid outlet, and an inner sealing mechanism 2 is connected in the first annular groove; a limiting ring 3 for contacting at the pipe mouth of the ship filling pipe is fixed on the outer tube surface of the liquid guide tube 1, and an outer sealing mechanism 4 for sealing sleeve arranged outside the ship filling pipe is fixed to the lower surface of the limiting ring 3; an oil gun connecting flange 5 for connecting an oil filling gun is provided at the liquid inlet.

[0028] The working principle and technical effects of the above technical solution are as follows: A drip-proof device for ship refueling of the present utility model can be hermetically installed on a refueling gun for use. An oil gun connection flange 5 for connecting the refueling gun is provided at the liquid inlet, facilitating its stable connection with the refueling gun. During refueling, the liquid guide pipe 1 is inserted into the ship refueling pipe, and the limit ring 3 is controlled to abut against the pipe orifice of the ship refueling pipe. At this time, the outer sealing mechanism 4 is sleeved on the outer pipe surface of the ship refueling pipe, and the inner sealing mechanism 2 connected in the first annular groove abuts against the inner pipe surface of the ship refueling pipe. The effective sealed connection between the liquid guide pipe 1 and the ship refueling pipe is realized through the outer sealing mechanism 4 and the inner sealing mechanism 2, reducing the probability of fuel leakage or dripping during refueling and effectively ensuring the refueling efficiency and refueling effect.

[0029] The inner sealing mechanism 2 includes a first sealing airbag 201. The first sealing airbag 201 is fixedly installed in the first annular groove. The first air inlet pipe 202 of the first sealing airbag 201 is hermetically fixed in the first pipe-passing hole 101 on the side of the liquid guide pipe 1. The first pipe-passing hole 101 communicates with the first air inflation port 102 fixed on the outer pipe surface of the liquid guide pipe 1. The first sealing airbag 201 is adhesively bonded in the first annular groove, and a first control valve is provided on the first air inflation port 102.

[0030] The first sealing airbag 201 is adhesively bonded in the first annular groove and is not easily dropped. After the liquid guide pipe 1 is inserted into the ship refueling pipe, an air pump is connected to the first air inflation port 102, and then the first control valve is opened to control the air pump to inject gas into the first pipe-passing hole 101 through the first air inflation port 102. The gas enters the first air inlet pipe 202 and the first sealing airbag 201 through the first pipe-passing hole 101, so that the first sealing airbag 201 expands, facilitating the first sealing airbag 201 to be hermetically attached to the inner pipe surface of the liquid guide pipe 1 to achieve effective sealing. The first sealing airbag 201 is supported by a corrosion-resistant rubber material, with good structural stability and not easily damaged. After inflation, the first control valve is closed. After refueling is completed, the first control valve is opened for deflation to facilitate the removal of the liquid guide pipe 1.

[0031] The outer sealing mechanism 4 includes a sleeving pipe 401 fixedly connected to the lower surface of the limit ring 3. One end of the inner side surface of the sleeving pipe 401 far from the limit ring 3 is fixedly connected with a sleeve ring 402 for fitting on the outer pipe surface of the ship refueling pipe. A second annular groove is provided on the inner ring surface of the sleeve ring 402, and a second sealing airbag 403 is connected in the second annular groove. The second air inlet pipe 404 of the second sealing airbag 403 is hermetically fixed in the second pipe-passing hole of the sleeving pipe 401 and penetrates above the limit ring 3, and a second control valve is provided on the second air inlet pipe 404.

[0032] The sleeve pipe 401 is sleeved outside the ship fuel filling pipe. The inner ring surface of the collar 402 is in sliding fit with the outer pipe surface of the ship fuel filling pipe. The use of the collar 402 and the liquid guiding pipe 1 ensures the stable installation of the present utility model. Then, the inflation pump is connected to the second air inlet pipe 404, and the second control valve is opened to control the inflation pump to inject gas into the second sealing airbag 403 through the second air inlet pipe 404, so that the second sealing airbag 403 expands, facilitating the second sealing airbag 403 to be hermetically attached to the outer pipe surface of the liquid guiding pipe 1 to achieve effective sealing. The second sealing airbag 403 is supported by a corrosion-resistant rubber material, with good structural stability and not easily damaged. After inflation, the second control valve is closed. After the fuel filling is completed, the second control valve is opened to deflate, facilitating the removal of the collar 402.

[0033] A drip liquid collection area is formed among the limiting ring 3, the sleeve pipe 401, the collar 402 and the liquid guiding pipe 1. An annular floating body 6 is arranged in the drip liquid collection area. The annular floating body 6 is sleeved on the liquid guiding pipe 1, and the middle part of the warning slide rod 7 fixedly connected to the annular floating body 6 is hermetically slid in the longitudinal through hole on the limiting ring 3.

[0034] The drip liquid collection area formed among the limiting ring 3, the sleeve pipe 401, the collar 402 and the liquid guiding pipe 1 is used to collect the fuel leaking between the liquid guiding pipe 1 and the ship fuel filling pipe. When the fuel in the drip liquid collection area gradually increases, it will cause the annular floating body 6 to float. The annular floating body 6 can be made of lightweight plastic. When the annular floating body 6 floats, it will make the length of the warning slide rod 7 extending above the limiting ring 3 become longer, facilitating the prompt to the staff about the leakage situation. A tension spring can also be fixedly connected between the annular floating body 6 and the limiting ring 3. The tension spring is sleeved on the warning slide rod 7, so that the annular floating body 6 maintains a relatively stable state under normal conditions and can only perform a floating movement when the buoyancy reaches a preset value.

[0035] A drip liquid discharge pipe 8 communicating with the drip liquid collection area is arranged on the side of the sleeve pipe 401. A third control valve is arranged on the drip liquid discharge pipe 8, and the output end of the drip liquid discharge pipe 8 is thread-sealed and connected to a transparent collection bag. After the drip liquid collection area collects the fuel leaking between the liquid guiding pipe 1 and the ship fuel filling pipe, the fuel can be discharged through the drip liquid discharge pipe 8 by opening the third control valve and can be collected into the transparent collection bag, which is energy-saving, environmentally friendly, reduces pollution and facilitates the subsequent removal of the present utility model.
