Description

Technical Field

[0001] The invention relates to the technical field of dry starting and idling operation of a stern engine of an unmanned boat, and in particular to an unmanned boat stern engine out-of-water idling device and a use method thereof. Background Art

[0002] As an unmanned device, the stern motor is an integrated main engine, shaft system, propeller and other components installed outside the ship as a propulsion method to drive the unmanned boat. As the main power equipment of the unmanned boat, the stern motor has the advantages of compact structure, light weight, easy installation, low noise, no need to set up a cabin, saving cabin space, and easy maintenance and replacement, and is widely used.

[0003] The start-up of the stern engine requires the impeller water pump to provide cooling water for the main engine. The impeller water pump needs to be immersed in water for starting. Starting out of water will cause dry friction between the impeller and the pump body, generating high temperature, which can easily cause the impeller to burn.

[0004] Based on the unmanned boat workflow, the status of the power propulsion system needs to be confirmed before each mission. This process is easy to perform when the unmanned boat is docked at the pier, but when the unmanned boat is carried on the mother ship, the entire boat is out of water, which is not conducive to the confirmation of the power propulsion system status.

[0005] In view of the above technical problems, an unmanned boat stern hanging machine out of water idling device and a use method are proposed. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an unmanned boat stern engine out of water idling device and a method of use. It only needs to fill the water tank with water when used for the first time, and it can automatically replenish water during subsequent use to achieve water circulation inside the system. When the stern engine is out of water, the bilge drainage pump can be started to inject water in the water tank into the stern engine to provide cooling water. When the stern engine is in a flooded state, the stern engine can re-inject part of the cooling water into the water tank to achieve automatic water replenishment of the water tank.

[0007] The present invention solves the technical problem by the following technical solutions:

[0008] An unmanned boat stern engine out of water idling device comprises a water tank, a water injection pipeline and a return water pipeline, a front end surface of the water tank is provided with a water injection port, one end of the water injection port is located in the water tank and is connected to a bilge drainage pump installed in the water tank through a drainage pipeline, one end of the water injection port is located outside the water tank and is connected to a stern engine water injection pipeline through the water injection pipeline, return water holes are provided on both sides of the water tank, the return water holes are connected to the stern engine drainage pipeline through the return water pipeline, and the water in the water tank is injected into the stern engine through the bilge drainage pump.

[0009] Furthermore, it also includes a one-way valve placed on the water injection pipeline.

[0010] Furthermore, there are two sets of water injection pipelines and water return pipelines on the left and right sides of the water tank, which are respectively used to connect two stern engines.

[0011] Furthermore, an overflow hole is formed at the front end of the water tank body, parallelly arranged mounting feet are formed on both sides of the water tank body, the return hole is located at the upper end of the mounting feet, and a pair of drain ports are formed at the bottom of the water tank body.

[0012] Furthermore, a pair of handles are installed on the water tank cover of the water tank, and a pair of artificial water injection ports are formed, and the artificial water injection ports are located at the front ends of the handles.

[0013] Furthermore, the water tank upper cover and the water tank body of the water tank are connected by a hinge.

[0014] Furthermore, the water tank upper cover of the water tank is clamped on the water tank body by a spring.

[0015] A method for using an unmanned boat stern engine off-water idling device comprises the following steps:

[0016] S1. Fix the water tank to the stern of the ship by installing the horse feet, and connect the water tank to the stern motor through the water filling pipeline and the water return pipeline;

[0017] S2. Connect the water injection port located at one end inside the water tank to the bilge drainage pump installed in the water tank through a drainage pipeline, and connect the water injection port located at one end outside the water tank to the stern engine water injection pipeline through a water injection pipeline;

[0018] S3, connect the return hole to the stern machine drainage pipe through the return pipe, connect the water injection pipe to the bilge drainage pump and the stern machine water injection channel, and connect the return pipe to the water tank and the stern machine drainage channel;

[0019] S4. Before dry starting the stern engine, turn on the bilge pump switch. After the bilge pump pumps the cooling water in the water tank into the stern engine water injection channel, the cooling water will seep from the stern engine propeller. At this time, the cooling water has been successfully injected into the stern engine water channel. Start the stern engine and ensure that the stern engine is in the idle state. After the stern engine enters the water, the water flow is introduced into the water tank through the return pipe to replenish the cooling water in the water tank. When the water level in the water tank reaches the maximum, the excess water can be discharged through the overflow hole on the tank body.

[0020] The advantages and positive effects of the present invention are:

[0021] 1. The unmanned boat stern engine out of water idling device of the present invention has a water tank and a stern engine connected through a water injection pipeline and a water return pipeline. The water injection port is located at one end in the water tank and is connected to the bilge drainage pump installed in the water tank through a drainage pipeline. The water injection port is located at one end outside the water tank and is connected to the stern engine water injection pipeline through the water injection pipeline. The return hole is connected to the stern engine drainage pipeline through the return pipeline. The water injection pipeline connects the bilge drainage pump and the stern engine water injection waterway. The return pipeline connects the water tank and the stern engine drainage waterway. Before the stern engine is dry-started, the bilge drainage pump switch needs to be turned on in advance. After the bilge drainage pump pumps the cooling water in the water tank into the stern engine water injection waterway, the cooling water will seep from the stern engine propeller, indicating that the cooling water has been successfully injected into the stern engine waterway. At this time, the stern engine can be started and it is ensured that the stern engine is in an idling state. When the stern engine enters the water, the water can be introduced into the water tank through the return pipe to replenish the cooling water in the water tank. When the water level in the water tank reaches the maximum, the excess water can be discharged through the overflow hole on the tank body. It can meet the needs of long-term dry start of the stern engine and facilitate the status detection of the stern engine during dry start.

[0022] 2. The unmanned boat stern engine out of water idling device of the present invention has a one-way valve arranged in the water injection pipeline to prevent the water of the stern engine from flowing back from the water injection pipeline after the stern engine is started after entering the water.

[0023] 3. The unmanned boat stern engine out of water idling device of the present invention has an overflow hole at the front end of the water tank body, and the overflow hole is used to limit the water level of the water tank. When the water level of the water tank reaches the height of the overflow hole, excess water can be discharged from the overflow hole.

[0024] 4. The unmanned boat stern engine out of water idling device of the present invention has parallelly arranged mounting feet on both sides of the water tank body, and the mounting feet provide mounting holes for the water tank.

[0025] 5. The unmanned boat stern engine out of water idling device of the present invention has a pair of handles installed on the water tank cover and a pair of artificial water filling ports. The handles are convenient for opening the water tank cover, and water can be filled into the water tank in advance through the artificial water filling ports.

[0026] 6. In the unmanned boat stern engine out-of-water idling device of the present invention, the water tank upper cover and the water tank body are connected by hinges, the water tank upper cover is opened and closed by the hinges, and the water tank upper cover is limited on the water tank body by a spring.

[0027] 7. The unmanned boat stern engine out of water idling device of the present invention uses the bilge drainage pump and the one-way valve to supply water to the stern engine water pump before the stern engine enters the water to prevent the water pump from being damaged. After the stern engine enters the water, the engine return water is used to replenish the water tank to ensure that the water level in the water tank is sufficient. In addition, when flushing the outboard engine waterway, fresh water can be added to the water tank and the bilge drainage pump can be used to flush the outboard engine waterway.

[0028] 8. The present invention only needs to fill the water tank with water when used for the first time, and can automatically replenish water during subsequent use to achieve water circulation within the system. When the stern engine is out of water, the bilge pump can be started to inject water in the water tank into the stern engine to provide cooling water. When the stern engine is submerged in water, the stern engine can re-inject part of the cooling water into the water tank to achieve automatic water replenishment of the water tank.

[0038] like Figures 1 to 6As shown, an unmanned boat stern engine out of water idling device includes a water tank 1, a water injection pipeline 4 and a return water pipeline 2. A water injection port 1.1 is formed on the front surface of the water tank 1. The water injection port 1.1 is located in the water tank 1 and connected to the bilge drainage pump 1.9 installed in the water tank 1 through a drainage pipeline 1.10. The water injection port 1.1 is located outside the water tank 1 and connected to the stern engine 3 water injection pipeline through the water injection pipeline 4. Return water holes 1.6 are formed on both sides of the water tank 1. The return water holes 1.6 are connected to the stern engine 3 drainage pipeline through the return water pipeline 2, and the water in the water tank 1 is injected into the stern engine 3 through the bilge drainage pump 1.9. There are two sets of water injection pipelines 4 and return water pipelines 2 on the left and right sides of the water tank 1, which are used to connect two stern engines 3 respectively.

[0039] A bilge drainage pump 1.9 is installed inside the water tank 1, which can inject water into the waterway of the stern motor 3 to provide cooling water for the stern motor 3, and has an automatic water storage function. The water tank 1 is made of stainless steel anti-corrosion material and can be fixed to the unmanned boat platform through the mounting feet 1.7 on the water tank body 1.13. After the stern motor 3 enters the water, the cooling water discharged from the stern motor 3 can be reintroduced into the water tank 1 through the return water pipeline 2 to replenish the water volume of the water tank 1. The water injection pipeline 4 injects the water discharged from the water tank 1 into the water injection waterway of the stern motor 3 to provide cooling water for the stern motor 3.

The water return hole 1.6 is welded to the water tank body 1.13 and connects the return water pipeline 2 and the water tank body 1.13. The bilge pump 1.9 is installed at the bottom of the water tank 1. Before the stern motor 3 enters the water, the bilge pump 1.9 and the check valve 5 are used to supply water to the water pump of the stern motor 3 to prevent the water pump from being damaged. After the stern motor 3 enters the water, the engine return water is used to replenish the water tank 1 to ensure that the water level of the water tank 1 is sufficient. In addition, when flushing the outboard motor waterway, fresh water can be added to the water tank 1 and the bilge pump 1.9 can be used to flush the outboard motor waterway.

[0040] The one-way valve 5 is also provided on the water injection pipeline 4. The one-way valve 5 is provided in the water injection pipeline 4 to prevent the water of the stern engine 3 from flowing back from the water injection pipeline 4 after the stern engine 3 is started by entering the water.

[0041] The front end of the water tank body 1.13 of the water tank 1 is provided with an overflow hole 1.3, and the two sides of the water tank body 1.13 are provided with parallel arranged mounting feet 1.7, the return water hole 1.6 is located at the upper end of the mounting feet 1.7, and the bottom of the water tank body 1.13 is provided with a pair of drain ports 1.8.

The water tank cover 1.12 of the water tank 1 is limited on the water tank body 1.13 by a spring clip 1.11.

[0044] Working principle of the present invention:

[0045] The water tank 1 is fixed to the stern of the ship by installing a foot 1.7. The water tank 1 is connected to the stern motor 3 through a water injection pipeline 4 and a water return pipeline 2. The water injection port 1.1 is located at one end in the water tank 1 and is connected to a bilge drainage pump 1.9 installed in the water tank 1 through a drainage pipeline 1.10. The water injection port 1.1 is located at one end outside the water tank 1 and is connected to the water injection pipeline of the stern motor 3 through the water injection pipeline 4. The return hole 1.6 is connected to the drainage pipeline of the stern motor 3 through the return pipeline 2. The water injection pipeline 4 is connected to the bilge drainage pump 1.9 and the water injection waterway of the stern motor 3. The return pipeline 2 is connected to the water tank 1 and the drainage waterway of the stern motor 3.

[0046] Before dry starting the stern engine 3, the bilge pump 1.9 switch must be turned on in advance. After the bilge pump 1.9 pumps the cooling water in the water tank 1 into the water injection channel of the stern engine 3, the cooling water will seep from the propeller of the stern engine 3, indicating that the cooling water has been successfully injected into the water channel of the stern engine 3. At this time, the stern engine 3 can be started and the stern engine 3 can be ensured to be in an idle state. After the stern engine 3 enters the water, the water flow can be introduced into the water tank 1 through the return pipe 2 to supplement the cooling water in the water tank 1. When the water level in the water tank 1 reaches the maximum, the excess water can be discharged through the overflow hole 1.3 on the tank body.

[0047] A method for using an unmanned boat stern engine off-water idling device comprises the following steps:

[0048] S1, fix the water tank 1 to the stern of the ship by installing the foot 1.7, and connect the water tank 1 and the stern motor 3 through the water injection pipe 4 and the return pipe 2;

[0049] S2, connect the end of the water injection port 1.1 located inside the water tank 1 to the bilge drainage pump 1.9 installed inside the water tank 1 through the drainage pipe 1.10, and connect the end of the water injection port 1.1 located outside the water tank 1 to the water injection pipe of the stern engine 3 through the water injection pipe 4;

[0050] S3, connect the return hole 1.6 to the drainage pipe of the stern engine 3 through the return pipe 2, connect the water injection pipe 4 to the bilge drainage pump 1.9 and the water injection channel of the stern engine 3, and connect the return pipe 2 to the water tank 1 and the drainage channel of the stern engine 3;

[0051] S4. Before the dry start of the stern engine 3, turn on the switch of the bilge drainage pump 1.9. After the bilge drainage pump 1.9 pumps the cooling water in the water tank 1 into the water injection channel of the stern engine 3, the cooling water will seep from the propeller of the stern engine 3. At this time, the cooling water has been successfully injected into the water channel of the stern engine 3. Start the stern engine 3 and ensure that the stern engine 3 is in an idle state. After the stern engine 3 enters the water, the water flow is introduced into the water tank 1 through the return pipe 2 to supplement the cooling water in the water tank 1. When the water level in the water tank 1 reaches the maximum, the excess water can be discharged through the overflow hole 1.3 on the tank body.

[0052] The present invention only needs to fill the water tank 1 with water when it is used for the first time, and can automatically replenish water during subsequent use to achieve water circulation inside the system. When the stern engine 3 is out of water, the bilge pump 1.9 can be started to inject water in the water tank 1 into the stern engine 3 to provide cooling water. When the stern engine 3 is in a flooded state, the stern engine 3 can re-inject part of the cooling water into the water tank 1 to achieve automatic water replenishment of the water tank.
