Description

Technical Field

[0001] The invention relates to the technical field of outboard motors, in particular to a waterproof spray pump type outboard motor. Background Art

[0002] An outboard motor is a detachable power device suspended on the stern of a boat or yacht that can propel the boat or yacht to sail. It is also called an outboard motor, a boat operating motor, or a hanging motor. It is mainly composed of an engine and transmission, operation, suspension devices, and propellers.

[0003] At present, the jet pump type outboard motor in the prior art generally does not have an anti-loss and anti-damage design during use. When the equipment is lost or accidentally falls into the water, it sinks to the bottom of the water and exceeds the pressure limit, which may cause damage or loss. When the jet pump type outboard motor sinks to the bottom of the water, due to its own design and structural characteristics, once the water depth exceeds its pressure limit, it is easy to cause damage to the internal parts. At the same time, for some high-performance jet pump type outboard motors, their cost is often high. Once lost or damaged, this situation not only makes the equipment lose its original use value, but also brings unnecessary economic losses to the ship owner. In view of this, the present invention proposes a waterproof jet pump type outboard motor. Summary of the invention

[0005] To achieve the above-mentioned object, the present invention proposes a waterproof spray pump type outboard motor, comprising an outboard motor assembly and a pressure-resistant shell. A protective mechanism is provided on the top of the pressure-resistant shell, a pull handle is provided on the lower side of the protective mechanism, a water pump is provided on the lower side of the protective mechanism, and the protective mechanism comprises: The pressure-resistant shell 2 is fixedly connected to the top of the pressure-resistant shell 1, a cavity is opened inside the pressure-resistant shell 2, the pulling handle is hinged at the bottom of the pressure-resistant shell 2, and the water pump is fixedly installed at the bottom of the pressure-resistant shell 2; A heat conducting plate, the heat conducting plate is fixedly connected to the inner wall of the second pressure-resistant shell, a vent hole 1 is opened on the outer wall of the heat conducting plate, an engine is fixedly installed in the second pressure-resistant shell, and a vent hole 2 is opened on the outer wall of the second pressure-resistant shell; And an anti-damage component, which is arranged inside the pressure-resistant shell two. Through the use of vent one and vent two, when the engine of the device is working, air can circulate inside the pressure-resistant shell two, so that the engine can dissipate heat normally. Through the use of a water pump, water can be sucked into the cavity, and the water in the cavity can also be discharged. In this way, the heat conduction plate can be water-cooled to improve the heat dissipation effect of the engine.

[0006] Preferably, both the vent 1 and the vent 2 are provided with switch valves.

[0007] Preferably, a rotating shaft is fixedly connected to the output end of the engine, and a driving bevel gear is fixedly connected to the bottom end of the rotating shaft.

[0008] Preferably, the anti-damage component includes a piston plate, which is slidably connected to the surface of the pressure-resistant shell 2 and the heat-conducting plate. An elastic telescopic rod is fixedly connected to the inner wall of the pressure-resistant shell 2, and the telescopic end of the elastic telescopic rod is connected to the piston plate.

[0009] Preferably, a compression chamber is fixedly connected to the inner wall of the second pressure-resistant shell, a through pipe is fixedly connected to the outer wall of the compression chamber, a sleeve is sleeved on the outer wall of the through pipe, and the sleeve is connected to the piston plate.

[0010] Preferably, a through hole is provided on the outer wall of the piston plate, and the through hole is communicated with the sleeve, the through hole of the piston plate is elastically connected to a baffle via a torsion spring, a solenoid valve is provided on the through pipe, an abutment block is fixedly connected to the outer wall of the sleeve, a contact switch is fixedly connected to the lower side of the compression chamber, compressed gas is stored in the compression chamber, and when the device accidentally falls off into the water, once the switch valve of the second vent is not closed in time, too much water flows into the cavity and the device gradually sinks, and the water flows continuously into the cavity, and then the piston plate slides upward, thereby driving the sleeve to move upward, so that the abutment block abuts against the contact switch, and at this time the contact switch controls the solenoid valve to open, and the compressed air in the compression chamber will be ejected, squeezing and discharging the gas in the cavity, so that the device can float and will not sink to the bottom, thereby preventing the loss of the device.

[0011] Preferably, the external machine component includes a shell, the inner surface of the shell is fixedly connected to a limiting sleeve, the inner surface of the limiting sleeve is rotatably connected to an impeller, the impeller is fixedly connected to a connecting shaft, and the end of the connecting shaft away from the impeller is fixedly connected to a driven bevel gear.

[0012] Preferably, the driven bevel gear is meshed with the driving bevel gear, a protective sleeve is fixedly connected to the inner surface of the shell, and the driven bevel gear and the driving bevel gear are arranged in the protective sleeve. The output shaft of the engine rotates to drive the rotating shaft to rotate, and then drives the driving bevel gear to rotate. Under the transmission action of the driven bevel gear, the impeller rotates, thereby completing the propulsion of the device. The protective sleeve can protect the driving bevel gear and the driven bevel gear when they are working.

[0013] Preferably, the rotating shaft passes through the shell and is rotatably connected to the shell, and the connecting shaft passes through the protective sleeve and is rotatably connected to the protective sleeve.

The U-shaped connector is fixedly connected to the output shaft of the stepper motor, and the output shaft of the stepper motor rotates to drive the U-shaped connector to rotate, so that the deceleration device rotates. By turning off the engine and starting the output shaft of the stepper motor to rotate, the U-shaped connector is driven to rotate, and the deceleration device rotates. When the deceleration device is parallel to the shell, the water flow impacts the shell, and the water flow is separated from the two groups of arc plates, generating greater resistance.

[0015] The present invention provides a waterproof jet pump outboard motor, which has the following beneficial effects: (1) The waterproof spray pump type outboard motor uses a protective mechanism. When the device accidentally falls into the water and the switch valve of the second vent is not closed in time, as the water continues to flow into the cavity, the piston plate will slide upward and drive the sleeve to move so that the abutment block abuts against the contact switch. At this time, the contact switch controls the solenoid valve to open, and the compressed gas in the compression chamber is ejected, squeezing the gas in the cavity out, so that the device can float up and avoid sinking to the bottom and being lost.

[0016] (2) The waterproof jet pump outboard motor has vent 1 and vent 2, so that air can circulate inside the pressure hull 2 ​​when the engine is working, ensuring normal heat dissipation of the engine. At the same time, the use of a water pump can draw water into the cavity and cool the heat conduction plate by water cooling, further improving the heat dissipation effect of the engine.

[0017] (3) The waterproof jet pump outboard motor has greatly optimized the lightweight design of the equipment through its innovative pillar-less structure, making the weight of the whole machine relatively light and meeting the needs of two people operating it at the same time. At the same time, the pillar-less structure also optimizes the control of the center of gravity during transportation and improves the convenience of two people operating it from the side. The lightweight design not only improves the portability and operability of the equipment, but also helps to improve the overall performance and response speed of the equipment, making it more suitable for rapid deployment and flexible operation in extreme environments.

[0024] In the embodiment of the present invention, in order to enable the device to have a good protection effect when used, specifically, the protection mechanism 3 includes a pressure-resistant shell 2 31, a heat-conducting plate 33 and an anti-damage component 35, the pressure-resistant shell 2 31 is fixedly connected to the top of the pressure-resistant shell 2, a cavity 32 is opened inside the pressure-resistant shell 2 31, the pull handle 4 is hinged at the bottom of the pressure-resistant shell 2 31, the water pump 5 is fixedly installed at the bottom of the pressure-resistant shell 2 31, the heat-conducting plate 33 is fixedly connected to the inner wall of the pressure-resistant shell 2 31, a vent 1 36 is opened on the outer wall of the heat-conducting plate 33, an engine 34 is fixedly installed in the pressure-resistant shell 2 31, a vent 2 37 is opened on the outer wall of the pressure-resistant shell 2 31, and the vent 1 36 and the vent 37 are connected to each other. The second vent 37 is provided with a switch valve, and the anti-damage component 35 is arranged inside the pressure-resistant shell 31. The pressure-resistant shell 31 and the pressure-resistant shell 2 have high pressure resistance, so that the parts therein can be well protected when the device is used in water. At the same time, through the use of the vent 1 36 and the vent 2 37, when the engine 34 of the device is working, air can circulate inside the pressure-resistant shell 31, so that the engine 34 can dissipate heat normally.

The whole machine is designed with a 110% positive buoyancy feature to ensure that the equipment will not sink to the bottom of the water and exceed the pressure limit in the event of detachment from the platform and loss, resulting in the loss of the equipment.

Under the transmission action of the driven bevel gear 105, the impeller 103 rotates, and then the propulsion of the device is completed. When deceleration is required, the engine 34 is turned off, and the output shaft of the stepper motor is started to rotate, driving the U-shaped connecting piece 1061 to rotate, so that the deceleration device 106 rotates. When the deceleration device 106 is parallel to the housing 101, the water flow impacts the housing 101, and the water flow is separated from the two sets of arc plates 1062, generating a large resistance, thereby achieving rapid deceleration of the device; At the same time, by using the vent 1 36 and the vent 2 37, when the engine 34 of the device is working, air can circulate inside the pressure shell 2 31, so that the engine 34 can dissipate heat normally.
