Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, specifically a ventilator structure for depth sounding on a bulk carrier. Background Technology

[0002] Bulk carriers are short for bulk cargo ships, which are ships specifically designed to transport bulk cargo that does not require packaging. The ship's generally enclosed compartments, such as liquid tanks, are equipped with vent pipes. In conventional designs, the vent pipes are led out from a relatively high position on the top or side of the compartment to facilitate the exchange and expulsion of air during the liquid filling process, thereby ensuring the effective loading of the compartment and preventing structural damage caused by excessive pressure changes.

[0003] A search revealed a Chinese patent, CN216401736U, which discloses a ventilated pipe for preventing water from entering the hold of a bulk carrier. The patent describes a first ring, a second ring fixedly installed at the upper end of the first ring, a third ring fixedly installed at the upper end of the second ring, and a first filter screen fixedly installed in the middle of the inner surface of the first ring.

[0004] The above-mentioned ventilation pipe is designed with a waterproof cover. If the cover is damaged, seawater or rainwater will directly enter from the inner cavity of the third ring, fall through the fan-shaped hole to the outer surface of the first truncated cone and the outer side of the upper end of the first mounting ring for storage, and be discharged from the conduit located in the middle of the outer surface of the second ring by the swaying of the hull, so as to ensure that the pressure inside the cabin is in a relatively balanced state and to ensure the integrity of the cabin.

[0005] However, its vent pipe is upright and easily damaged. It also has poor rainwater blocking effect. Furthermore, it relies on a baffle to block rain, which is a simple structure. It is difficult to actively close it as needed, making it less flexible in use. In addition, it relies on pressure to open the vent pipe and lacks active ventilation measures, resulting in poor performance. Utility Model Content

[0006] The purpose of this invention is to provide a structure for a depth sounding and ventilation pipeline for bulk carriers, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A depth sounding venting pipeline structure for a bulk carrier includes a depth sounding venting pipe body, an active exhaust pipe, and an extension pipe. The depth sounding venting pipe body, the active exhaust pipe, and the extension pipe are connected by a sealing flange, and the active exhaust pipe is located between the upper and lower ends of the depth sounding venting pipe body and the extension pipe. An exhaust pipe is fixedly installed on one side of the depth sounding venting pipe body.

[0009] An installation plate is fixedly connected to the upper part of the depth sounding vent tube body. A movable rod is movably installed through the upper and lower ends of the installation plate. A sealing piston plate is fixedly installed at the bottom end of the movable rod. An exhaust plate is fixedly connected to the lower part of the depth sounding vent tube body. The bottom surface of the sealing piston plate is in contact with the top surface of the exhaust plate. Ventilation ports are provided on both sides through the upper and lower ends of the exhaust plate. A return spring is provided around the outer ring of the sealing piston plate. The upper and lower ends of the return spring are fixedly connected to the upper and lower opposite surfaces of the sealing piston plate and the installation plate, respectively.

[0010] An exhaust valve is provided at the end of the vent pipe away from the body of the depth sounding vent pipe, and an exhaust one-way valve is provided at the connection between the vent pipe and the body of the depth sounding vent pipe. An exhaust duct is fixedly connected to the outer ring of the active exhaust pipe on the side away from the vent pipe, and an active exhaust valve is installed on the side of the exhaust duct away from the active exhaust pipe.

[0011] Preferably, the bottom end of the sealing piston plate is fixedly connected to a plug that is compatible with the vent, and the plug is inserted into the vent.

[0012] Preferably, an air exchange pipe adapted to the exhaust plate is connected to both sides of the exhaust plate and the depth sounding vent pipe body, and an air intake one-way valve is provided at the connection between the air exchange pipe and the depth sounding vent pipe body.

[0013] Preferably, the exhaust duct is a hollow pipe, and a ventilation fan is installed inside the exhaust duct via a mounting bracket.

[0014] Preferably, the outer ring of the sealing piston plate is fitted with the inner wall of the depth sounding ventilator body, and the sealing piston plate and the depth sounding ventilator body are slidably connected.

[0015] Preferably, the top end of the movable rod does not contact the inner top end of the depth sounding vent pipe body, and the outer ring of the movable rod is provided with an external thread at the upper position, and a limit nut is connected through the external thread. The bottom surface of the limit nut is in contact with the top surface of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, by setting up an exhaust pipe, an exhaust valve, and a depth sounding ventilator body, reduces the probability of rainwater backflow during ventilation because the exhaust pipe is set at a right angle instead of a straight pipe, thus preventing rainwater from entering the chamber from the depth sounding ventilator body. Furthermore, the exhaust valve can be manually closed, and the non-fixed open design provides high flexibility in use.

[0018] By using the exhaust duct, active exhaust valve, and active exhaust pipe in conjunction with the depth sounding ventilator, the active exhaust valve can be opened and the ventilation fan inside the exhaust duct can be started when needed, enabling active ventilation. Furthermore, by inserting a plug at the vent of the exhaust plate, rainwater can be prevented from entering through the ventilation pipe. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Combination Figures 1-4 A depth sounding venting pipeline structure for a bulk carrier includes a depth sounding venting pipe body 1, an active exhaust pipe 2, and an extension pipe 3. The depth sounding venting pipe body 1, the active exhaust pipe 2, and the extension pipe 3 are connected by a sealing flange, and the active exhaust pipe 2 is located between the upper and lower ends of the depth sounding venting pipe body 1 and the extension pipe 3. An exhaust pipe 4 is fixedly installed on one side of the depth sounding venting pipe body 1.

[0027] See Figure 2 and Figure 3Furthermore, it is found that an installation plate 7 is fixedly connected to the upper part of the interior of the depth sounding vent tube body 1, a movable rod 8 is movably installed through the upper and lower ends of the installation plate 7, a sealing piston plate 9 is fixedly installed at the bottom end of the movable rod 8, an exhaust plate 11 is fixedly connected to the lower part of the interior of the depth sounding vent tube body 1, the bottom surface of the sealing piston plate 9 is in contact with the top surface of the exhaust plate 11, and vents are provided at both the upper and lower ends of the exhaust plate 11 near both sides. A return spring 10 is provided around the outer ring of the sealing piston plate 9, and the upper and lower ends of the return spring 10 are fixedly connected to the upper and lower opposite surfaces of the sealing piston plate 9 and the installation plate 7, respectively.

[0028] The bottom end of the sealing piston plate 9 is fixedly connected to a plug 12 that is compatible with the vent, and the plug 12 is inserted into the vent. It passes through the exhaust plate 11 and is connected to both sides of the depth sounding vent tube body 1 by an air exchange pipe 13 that is compatible with the exhaust plate 11. An air inlet one-way valve 14 is provided at the connection between the air exchange pipe 13 and the depth sounding vent tube body 1. The outer ring of the sealing piston plate 9 is in contact with the inner wall of the depth sounding vent tube body 1, and the sealing piston plate 9 and the depth sounding vent tube body 1 are slidably connected. The top of the movable rod 8 does not contact the inner top of the depth sounding vent tube body 1. The outer ring of the movable rod 8 is provided with an external thread at the upper position, and a limit nut is connected through the external thread. The bottom surface of the limit nut is in contact with the top surface of the mounting plate 7.

[0029] Specifically, when the pressure inside the sounding vent pipe body 1, the active exhaust pipe 2, and the extension pipe 3 is high, the sealing piston plate 9 can be pushed upwards. At this time, the sealing piston plate 9 drives the block 12 to disengage from the vent of the exhaust plate 11, so that the ventilation pipe 13 and the exhaust port form a passage. Because the intake one-way valve 14 is one-way, the gas will not be discharged, and the pressure will not be released. Continue to push the sealing piston plate 9 upwards until the bottom surface of the sealing piston plate 9 exceeds the outlet pipe 4, then exhaust will be performed to release pressure. At the same time, external gas will be discharged. When the air is ventilated, it will enter the depth sounding ventilator body 1 from the ventilation pipe 13 to complete the ventilation. When the sealing piston plate 9 rises, it will compress the return spring 10. After the sealing piston plate 9 vents, the pressure gradually decreases. Thus, the return spring force of the return spring 10 can push the sealing piston plate 9 back to the top surface of the exhaust plate 11 and make the block 12 lock into the vent of the exhaust plate 11 again to complete the ventilation process. After the sealing piston plate 9 is reset, the vent of the exhaust plate 11 will be sealed again to prevent rainwater or seawater from entering.

[0030] Example 2

[0031] See Figure 2 and Figure 4Furthermore, based on Embodiment 1, an exhaust valve 6 is provided at the end of the exhaust pipe 4 away from the depth sounding vent pipe body 1, and an exhaust one-way valve 5 is provided at the connection between the exhaust pipe 4 and the depth sounding vent pipe body 1. An exhaust duct 15 is fixedly connected to the outer ring of the active exhaust pipe 2 on the side away from the exhaust pipe 4, and an active exhaust valve 16 is installed on the side of the exhaust duct 15 away from the active exhaust pipe 2. The exhaust duct 15 is a hollow pipe, and a ventilation fan is installed inside the exhaust duct 15 through a mounting bracket.

[0032] Specifically, active ventilation can be achieved by opening the active exhaust valve 16 and starting the ventilation fan at the exhaust duct 15. In suitable weather conditions, the exhaust valve 6 can be manually closed to prevent rainwater from entering the exhaust pipe 4. Both the exhaust pipe 4 and the ventilation pipe 13 are right-angle exhaust pipes, which can prevent rainwater backflow to a certain extent. At the same time, the exhaust one-way valve 5 is designed to prevent rainwater from entering through the exhaust pipe 4, thereby improving the performance.

[0033] In actual operation, when the pressure inside the sounding vent pipe body 1, the active exhaust pipe 2, and the extension pipe 3 is large, the sealing piston plate 9 can be pushed upward. At this time, the sealing piston plate 9 drives the block 12 to disengage from the vent of the exhaust plate 11, so that the ventilation pipe 13 and the exhaust port form a passage.

[0034] Because the intake one-way valve 14 is set in one direction, the gas will not be discharged. At this time, the pressure is not released. Continue to push the sealing piston plate 9 upward until the bottom surface of the sealing piston plate 9 exceeds the outlet pipe 4. Then the gas will be discharged to release the pressure. At the same time, when the external gas is discharged, it will enter the depth sounding vent pipe body 1 from the ventilation pipe 13 to complete the ventilation.

[0035] When the sealing piston plate 9 rises, it will compress the return spring 10. After the sealing piston plate 9 exhausts the air, the pressure gradually decreases. Thus, the return spring force of the return spring 10 can push the sealing piston plate 9 back to the top surface of the exhaust plate 11 and make the block 12 get stuck in the vent of the exhaust plate 11 again to complete the ventilation process. After the sealing piston plate 9 is reset, the vent of the exhaust plate 11 will be sealed again to prevent rainwater or seawater from entering.

[0036] Active ventilation can be achieved by opening the active exhaust valve 16 and starting the ventilation fan at the exhaust duct 15. In suitable weather conditions, the exhaust valve 6 can be manually closed to prevent rainwater from entering the exhaust pipe 4. Both the exhaust pipe 4 and the ventilation pipe 13 are right-angle exhaust pipes, which can prevent rainwater backflow to a certain extent. At the same time, the exhaust one-way valve 5 is designed to prevent rainwater from entering through the exhaust pipe 4, thereby improving the performance.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
