Description

Technical Field

[0001] This patent relates to the technical field of testing devices, and in particular to an indoor water tank testing device for outboard engines. Background Art

[0002] Fast boats have the advantages of being light and high-speed. They are currently the main light water transport tools in the military and civilian markets. Outboard motors have the characteristics of quick installation and combinable use, making them a major power type for fast boats. Users can combine different numbers of outboard motors to meet the requirements of boat power that matches the speed and transport load. It is difficult to test the power and torque of its propeller characteristics underwater, and the test accuracy is not high. The more mature test bench equipment is a simulated water test bench on land with a water tank and a centering device, and its centering device is directly connected to the output shaft of the propeller. Therefore, for the above detection device, the detection device refers to the vertical tooth outboard motor detection equipment with the crankshaft vertically clamped, which has the following shortcomings:

[0003] First, the engine transmits power to the propeller shaft through a transmission. The aforementioned alignment device measures the propeller shaft's dynamic characteristics, that is, the engine's load characteristics. However, converting the propeller shaft into a propeller's propeller characteristics is difficult to measure and calculate. This is because the propeller and propeller shaft are connected by a flexible, not a rigid, connection, and contain a rubber member, making dynamic calculation difficult.

[0004] Second, since the measurements are conducted on land, it is difficult to simulate the underwater test conditions.

[0005] Third, outboard motors have two gears: forward and reverse. The above test benches cannot test the power characteristics of outboard motors in reverse. The dynamometers currently used to test product power can only test engine power.

[0006] Fourth, when the outboard motor is actually working on the water, the lifting device will cause the outboard motor to have different postures, and the existing test equipment cannot meet the requirements of testing the power characteristics of the outboard motor under different postures. This is because the real-time monitoring of the propeller characteristic test data under different postures and the generation of test reports are not timely collected.

[0007] Based on the above shortcomings, it is necessary to make improvements. Summary of the Invention

[0008] In response to the above-mentioned deficiencies in the prior art, the purpose of this patent is to provide an outboard motor indoor water tank testing device, which is suitable for installation in an indoor outboard motor test water tank, and the testing device includes a first profile portion, a second profile portion and a first mounting portion; the first profile portion includes a first profile member horizontally mounted on the water tank, the second profile portion includes at least two second profile members inclined relative to the first profile member, and the first mounting portion is connected to the second profile member; the first mounting portion includes a mounting plate inclined relative to the first profile member and the second profile member, and the mounting plate includes a mounting hole for cooperating with the outboard motor bracket.

[0015] Furthermore, in some optional embodiments: the second profile member further includes positioning holes arranged at intervals, the first mounting seat and the second mounting seat include positioning mounting holes, and the positioning holes cooperate with the positioning mounting holes to install the first mounting portion.

[0016] Furthermore, in some optional embodiments: the angle between the mounting plate and the plane where the first mounting seat and the second mounting seat are located is A, wherein 0°<A≤30°.

[0017] Furthermore, in some optional embodiments: the outboard engine indoor water tank testing device also includes a second mounting portion arranged opposite to the first mounting portion, and the second mounting portion has the same structure as the first mounting portion.

[0018] After adopting the above structure, the advantages of this patent compared with the existing technology are: it can simulate the real sailing state of a multi-machine system with the outboard motor hung on the stern of the boat, and the structure is reasonable and easy to install, which can greatly reduce the testing cost.
