Description

Technical Field

[0001] This utility model relates to the field of ship cooling equipment technology, specifically to a ship adaptive self-flowing water inlet device. Background Technology

[0002] Cooling water systems are an important component of ship propulsion systems and a crucial aspect that must be addressed to further enhance ship performance. Gravity-flow cooling technology involves installing a gravity-flow water inlet device at the bottom of the ship. Utilizing the dynamic pressure of the water flowing towards the ship during navigation, water automatically flows through the gravity-flow water inlet device into the ship's cooling water system to cool the corresponding heat-generating equipment.

[0003] The supply capacity of gravity-flow cooling seawater is determined by the ship's speed. When the ship is sailing at high speed, the cooling seawater supply capacity of the gravity-flow device is also high. In actual navigation, the cooling seawater supply capacity of the gravity-flow device often exceeds the ship's heat removal requirements. There is an urgent need to design a ship adaptive gravity-flow water intake device that can adjust the seawater flow rate so that the cooling seawater supply capacity matches the ship's heat removal requirements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a ship adaptive adjustment gravity-flow water inlet device. By driving the gravity-flow pipe clamp and the gravity-flow pipe on it to rotate through the steering mechanism, the angle between the gravity-flow pipe inlet and the ship's sailing direction is changed, thereby achieving the effect of adjusting the cooling seawater flow rate. Thus, the cooling seawater flow rate under gravity-flow conditions can be adjusted according to actual needs.

[0005] The purpose of this utility model is achieved as follows:

[0006] A ship adaptive self-flowing water intake device includes a self-flowing pipe and a water supply pipe. The self-flowing pipe is L-shaped, with a water inlet at one end and a water supply pipe rotatably connected to the other end. The end of the self-flowing pipe with the water inlet is clamped and fixed by a self-flowing pipe clamping seat. The self-flowing pipe clamping seat is connected to a steering mechanism via a connecting plate. The steering mechanism includes a base plate, a drive motor, a gear, a rack, a steering rod, and an L-shaped bend plate. The gear is rotatably mounted in a mounting base, which is fixedly mounted on the base plate. The rack, which meshes with the gear, is slidably mounted in the mounting base. The gear is driven to rotate by the drive motor. The two ends of the rack extend out of the mounting base and are symmetrically hinged to the steering rod. The steering rod is hinged to the L-shaped bend plate. The corner of the L-shaped bend plate is hinged to the base plate. One end of the L-shaped bend plate is hinged to the steering rod, and the middle of the other end is hinged to a connecting plate. The two sides of the connecting plate are respectively hinged to the L-shaped bend plates on the corresponding sides.

[0007] Preferably, the mounting base includes a slide groove, in which a rack is slidably connected. Support plates are provided on both sides of the slide groove. The gear is set between the two support plates via a rotating shaft. One end of the rotating shaft extends out of the support plate and is connected to a drive motor via a universal joint.

[0008] Preferably, one end of the L-shaped bent plate hinged connecting plate is also hinged to a connecting rod, and the connecting rod is simultaneously hinged to two L-shaped bent plates.

[0009] Preferably, the gravity flow pipe clamping seat includes a fixed pipe clamping seat and a movable pipe clamping seat. The fixed pipe clamping seat is fixed on the connecting plate. The fixed pipe clamping seat and the movable pipe clamping seat are connected by studs. The end of the gravity flow pipe with the inlet is clamped between the fixed pipe clamping seat and the movable pipe clamping seat. The fixed pipe clamping seat and the movable pipe clamping seat are provided with pipe grooves corresponding to the pipe diameter of the gravity flow pipe.

[0010] Preferably, there are four studs, which are fixedly installed at the four corners of the fixed tube clamp seat. After passing through the movable tube clamp seat, the studs are connected to the pressure plate and multiple anti-loosening nuts in sequence, wherein two studs share one pressure plate.

[0011] The beneficial effects of this utility model are:

[0012] The steering mechanism drives the gravity flow pipe clamp and the gravity flow pipe on it to rotate, changing the angle between the gravity flow pipe inlet and the ship's sailing direction, thereby adjusting the cooling seawater flow rate. This allows for the adjustment of the cooling seawater flow rate under gravity flow conditions according to actual needs. Attached Figure Description

Detailed Implementation

[0019] See Figure 1-4 This utility model relates to a ship adaptive adjustment gravity-flow water inlet device, including a steering mechanism 1, a gravity-flow pipe clamping seat 2, a gravity-flow pipe 3, and a water supply pipe 4. The gravity-flow pipe 3 is L-shaped, with a water inlet at one end and the other end rotatably connected to the water supply pipe 4. The end of the gravity-flow pipe 3 with the water inlet is clamped and fixed by the gravity-flow pipe clamping seat 2. The gravity-flow pipe clamping seat 2 is driven to rotate by the steering mechanism 1, which drives the gravity-flow pipe 3 to rotate, changing the angle between the gravity-flow pipe inlet and the ship's forward direction, thereby achieving the effect of adjusting the cooling seawater flow rate.

[0020] The steering mechanism 1 includes a base plate 1.1, a drive motor 1.2, a gear 1.3, a rack 1.4, a steering rod 1.5, and an L-shaped bend plate 1.6. The gear 1.3 is rotatably mounted in a mounting base 1.7, which is fixedly mounted on the base plate 1.1. The rack 1.4, which meshes with the gear 1.3, is slidably mounted in the mounting base 1.7. The gear 1.3 is driven to rotate by the drive motor 1.2. The two ends of the rack 1.4 extend out of the mounting base 1.7 and are symmetrically hinged to the steering rod 1.5. The steering rod 1.5 is hinged to the L-shaped bend plate 1.6. The corner of the L-shaped bend plate 1.6 is hinged to the base plate 1.1. One end of the L-shaped bend plate 1.6 is hinged to the steering rod 1.5, and the other end is hinged to a connecting rod 1.8. The connecting rod 1.8 is simultaneously hinged to both L-shaped bend plates 1.6, improving the rotational stability of the two L-shaped bend plates 1.6.

[0021] The mounting base 1.7 includes a slide groove 1.7.1, in which a rack 1.4 is slidably connected. Support plates 1.7.2 are provided on both sides of the slide groove 1.7.1. A gear 1.3 is set between the two support plates 1.7.2 via a rotating shaft 1.9. One end of the rotating shaft 1.9 extends out of the support plate 1.7.2 and is connected to the drive motor 1.2 via a universal joint 1.10.

[0022] The gravity flow pipe clamp 2 is connected to the L-shaped bend 1.6 via the connecting plate 5. The two sides of the connecting plate 5 are respectively hinged to the corresponding sides of the L-shaped bend 1.6. The hinge is close to the connecting rod 1.8. The gravity flow pipe clamp 2 includes a fixed pipe clamp 2.1 and a movable pipe clamp 2.2. The fixed pipe clamp 2.1 is fixed on the connecting plate 5. The fixed pipe clamp 2.1 and the movable pipe clamp 2.2 are connected by studs 2.3. The end where the inlet of the gravity flow pipe 3 is located is clamped between the fixed pipe clamp 2.1 and the movable pipe clamp 2.2. The fixed pipe clamp 2.1 and the movable pipe clamp 2.2 are provided with pipe grooves corresponding to the pipe diameter of the gravity flow pipe 3.

[0023] There are four studs 2.3, which are fixedly installed at the four corners of the fixed pipe clamp seat 2.1. The studs 2.3 pass through the movable pipe clamp seat 2.2 and are connected in sequence to the pressure plate 2.4 and multiple anti-loosening nuts 2.5. Two studs 2.3 share one pressure plate 2.4.

[0024] Working principle:

[0025] When the inlet of gravity flow pipe 3 is aligned with the direction of ship navigation, the maximum flow rate of gravity-flow seawater is achieved.

[0026] When it is necessary to adjust the flow rate of gravity-flow seawater, the drive motor 1.2 drives the gear 1.3 to rotate. The gear 1.3 drives the rack 1.4 to slide left and right within the mounting base 1.7. The symmetrical steering rod 1.5 drives the L-shaped bending plate 1.6 to rotate around the hinge point at the corner. The two L-shaped bending plates 1.6 rotate in the same direction, thereby driving the gravity-flow pipe clamping base 2 and the gravity-flow pipe 3 on it to rotate, so that the gravity-flow pipe inlet makes an angle with the ship's navigation direction, thereby realizing the adjustment of the flow rate (inlet volume) of gravity-flow seawater.

[0027] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
