Description

Technical Field

[0001] This utility model relates to the field of anti-sway technology for ship liquid tanks, specifically an anti-sway device for liquid tanks on river-sea direct vessels. Background Technology

[0002] The liquid tank on a river-sea direct transport vessel is a specially designed, sealed compartment structure for storing liquid cargo. It combines the design features of river vessels and seagoing vessels, enabling safe navigation on inland waterways while adapting to the maritime environment. Its structural strength, sealing performance, and corrosion resistance have all been specially optimized to ensure the stable and safe transport of various liquid cargoes during river-sea intermodal transport, reducing losses and risks.

[0003] In existing anti-sloshing devices for river-sea direct-ship vessels, multiple anti-sloshing plates are typically added longitudinally inside the tank to reduce liquid sloshing. However, these anti-sloshing plates can only block longitudinally sloshing liquid, not laterally sloshing liquid. Furthermore, these anti-sloshing plates are directly fixed to the inside of the tank, so when subjected to liquid impact, the impact force is still transmitted to the tank, resulting in poor anti-sloshing protection. To more effectively block liquid sloshing inside the tank and protect the tank structure, this application proposes an anti-sloshing device for river-sea direct-ship vessels. Utility Model Content

[0004] The purpose of this invention is to provide a sloshing prevention device for the liquid tank of a river-sea direct-ship vessel. This addresses the problem that existing sloshing prevention devices for river-sea direct-ship vessels typically add multiple sloshing prevention plates longitudinally inside the liquid tank to reduce liquid sloshing during use. However, these plates can only block longitudinally sloshing liquid and cannot block laterally sloshing liquid. Furthermore, these plates are directly fixed to the inside of the liquid tank, so when subjected to liquid impact, the impact force is still transmitted to the liquid tank, resulting in poor sloshing prevention and protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid tank anti-sway device for a river-sea direct-roaming vessel, comprising a liquid tank fixing base, a liquid tank being provided on the top of the liquid tank fixing base, two mounting shafts being symmetrically arranged at both ends of the inner side of the liquid tank, two transverse anti-sway plates being symmetrically arranged on the front and rear sides of the two mounting shafts respectively, two longitudinal anti-sway plates being symmetrically arranged on the left and right ends of the mounting shafts respectively, and multiple connecting rods being symmetrically arranged at the upper and lower ends of the multiple longitudinal anti-sway plates on the two mounting shafts that are close to each other.

[0006] The liquid tank fixing seat includes a base plate, an arc-shaped tank fixing seat is fixedly connected to the upper surface of the base plate, and the lower surface of the base plate is fixedly connected to the hull.

[0007] The liquid tank includes a tank body, with an infusion pipe fixedly connected to one end of the top of the tank body and a drain pipe fixedly connected to the bottom of one end of the tank body. The bottom of the tank body is fixedly connected to an arc-shaped tank body fixing seat. An infusion solenoid valve is movably connected to the inside of the infusion pipe, and a drain solenoid valve is movably connected to the inside of the drain pipe.

[0008] The two mounting shafts are rotatably connected to the upper and lower ends of the inner side of the cabin, respectively.

[0009] The two transverse anti-sway plates include two transverse baffles. Two clearance grooves are symmetrically arranged at the upper and lower ends of the two transverse baffles. The transverse baffles are fixedly connected to both sides of the mounting shaft, and there is a gap between the outer side of the transverse baffle and the inner wall of the cabin.

[0010] The two longitudinal anti-sway plates include two longitudinal baffles. Two mounting slots are symmetrically arranged at the upper and lower ends of the two longitudinal baffles. The longitudinal baffles are fixedly connected to the two sides of the mounting shaft, and there is a gap between the outer side of the longitudinal baffle and the inner wall of the cabin. The inner sides of the two mounting slots are respectively vertically fixedly connected to the fixing shaft.

[0011] The two ends of the multiple connecting rods are respectively rotatably connected to the fixed shafts on the two longitudinal baffles on the same side of the two mounting shafts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses multiple transverse and longitudinal anti-sloshing plates mounted on two mounting shafts at both ends of the liquid tank to block the sloshing liquid inside the tank, reducing the sloshing of the liquid and thus protecting the tank. Furthermore, multiple connecting rods connect the multiple longitudinal anti-sloshing plates at both ends, which can transmit the impact of the liquid at both ends on the multiple transverse and longitudinal anti-sloshing plates and make them cancel each other out, thereby improving the anti-sloshing and protective effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a liquid tank anti-sway device for a river-sea direct-roaming vessel, including a liquid tank fixing base 1, a liquid tank 2 is provided on the top of the liquid tank fixing base 1, two mounting shafts 3 are symmetrically arranged at both ends of the inner side of the liquid tank 2, two transverse anti-sway plates 4 are symmetrically arranged on the front and rear sides of the two mounting shafts 3 respectively, two longitudinal anti-sway plates 5 are symmetrically arranged on the left and right ends of the mounting shafts 3 respectively, and multiple connecting rods 6 are symmetrically arranged at the upper and lower ends of the multiple longitudinal anti-sway plates 5 on the two mounting shafts 3 that are close to each other.

[0016] The liquid tank fixing seat 1 includes a base plate 101, an arc-shaped tank fixing seat 102 is fixedly connected to the upper surface of the base plate 101, and the lower surface of the base plate 101 is fixedly connected to the hull. By setting the arc-shaped tank fixing seat 102, it is easier to fit better with the bottom of the liquid tank 2, thereby better fixing the liquid tank 2.

[0017] The liquid tank 2 includes a tank body 201. One end of the top of the tank body 201 is fixedly connected to a liquid infusion pipe 202, and one end of the bottom of the tank body 201 is fixedly connected to a liquid drain pipe 203. The bottom of the tank body 201 is fixedly connected to an arc-shaped tank body fixing seat 102. A liquid infusion solenoid valve 204 is movably connected to the inside of the liquid infusion pipe 202, and a liquid drain solenoid valve 205 is movably connected to the inside of the liquid drain pipe 203. By setting the liquid infusion solenoid valve 204 and the liquid drain solenoid valve 205, it is convenient to control the delivery and discharge of liquid inside the liquid tank 2.

[0018] The two mounting shafts 3 are rotatably connected to the upper and lower ends of the inner side of the chamber 201, respectively. By setting the two mounting shafts 3, the transverse anti-sloshing plate 4 and the longitudinal anti-sloshing plate 5 can be installed, which can block the transverse and longitudinal swaying liquid and reduce swaying.

[0019] Among them, the two transverse sway stop plates 4 include two transverse baffles 401. Two clearance grooves 402 are symmetrically arranged at the upper and lower ends of the two transverse baffles 401. The transverse baffles 401 are fixedly connected to both sides of the mounting shaft 3, and there is a gap between the outer side of the transverse baffles 401 and the inner wall of the cabin 201. By setting two clearance grooves 402, the connecting rod 6 can be avoided, and the transverse sway stop plate 4 can avoid collision with the connecting rod 6 during rotation, thus protecting the transverse sway stop plate 4 and the connecting rod 6.

[0020] Among them, the two longitudinal anti-sloshing plates 5 include two longitudinal baffles 501. Two mounting grooves 502 are symmetrically arranged at the upper and lower ends of the two longitudinal baffles 501. The longitudinal baffles 501 are fixedly connected to both sides of the mounting shaft 3, and there is a gap between the outer side of the longitudinal baffles 501 and the inner wall of the chamber 201. The inner side of the two mounting grooves 502 is vertically fixedly connected to the fixing shafts 503. By setting multiple fixing shafts 503, the connecting rods 6 can be installed to connect the two longitudinal anti-sloshing plates 5 on the mounting shafts 3 at both ends to each other, so as to counteract the energy generated by the sloshing of the liquid at both ends.

[0021] Among them, the two ends of multiple connecting rods 6 are respectively rotatably connected to the fixed shafts 503 on the two longitudinal baffles 501 on the same side of the two mounting shafts 3. By setting multiple connecting rods 6, the multiple longitudinal baffles 501 on the two mounting shafts 3 at both ends can be connected to each other, thereby transmitting the energy generated by the liquid sloshing at both ends and making them cancel each other out, thus improving the protection effect.

[0022] Working principle: Open the infusion solenoid valve 204 to input liquid into the chamber 201 through the infusion pipe 202, and then close the infusion solenoid valve 204. When liquid is needed, open the drain solenoid valve 205 to drain liquid from the chamber 201 through the drain pipe 203. When the ship moves, the waves on the water surface collide with the ship, causing the hull to sway, which in turn causes the liquid inside the liquid tank 2 to sway. During this process, the liquid at both ends of the chamber 201 impacts and contacts multiple transverse anti-sway plates 4 and longitudinal anti-sway plates 5 on the two mounting shafts 3, which in turn causes the two mounting shafts 3 to rotate. This causes multiple longitudinal baffles 501 to transmit impact energy through multiple connecting rods 6, thereby canceling out the energy generated by the swaying liquid at both ends.

[0023] 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.
