Problems solved by technology

The structure of this kind of measuring device is relatively complicated, the operation process is cumbersome, and the measurement accuracy is low.
In addition, at present, when performing thrust tests on underwater propellers, the underwater propellers are mostly placed in square water storage tanks. When the underwater propellers are started, the pushed water flow meets the inner wall of the square water storage tank and turns back to cause turbulent flow. It will also affect the thrust test of the underwater thruster

Embodiment Construction

[0023] Such as figure 1 , 2 As shown, the underwater thruster test device includes a water tank 1, and water flows into the water tank 1, which is used for the simulation test of the underwater thruster. It can be seen from the figure that the shape of the water tank 1 is elongated, and the front and rear ends are provided with radians. An elongated card slot 3 is provided inside the water tank 1 . The left and right straight sections and the front and rear arc sections are formed between the water tank 1 and the card slot 3, and the left and right straight sections and the front and rear arc sections are connected to form an annular water tank, which can be lowered The effect of turbulence on propeller thrust testing.

[0024] For the convenience of the measurement of the propeller, a support 2 is installed on the left side of the water tank 1, and the draw-in groove 3 is used to assist in fixing the support 2. As shown in the figure, the shape of the support 2 is a square...

Abstract

The invention discloses an underwater propeller testing device which comprises an elongated water tank. An elongated clamping groove is arranged inside the elongated water tank in a sleeved manner, and a left-right linear section and a front-rear arc-shaped section are formed between the elongated water tank and the elongated clamping groove and are communicated to form an annular water tank; a supporting frame is arranged on the left-side or right-side linear section of the annular water tank, a rail is mounted on the supporting frame, a propeller support is mounted on the rail, a propeller is fixed at the lower end of the propeller support, and the propeller support slides along the rail through a slider; a press piece is arranged at the upper end of the propeller support, a pressure sensor matched with the press piece is arranged at one end of the supporting frame, and the press piece and the pressure sensor are on a same straight line. The underwater propeller testing device effectively lowers impact of turbulence on propeller thrust testing, improves testing accuracy, is simple in design and convenient and quick to operate, meets market needs and has great market prospect.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an underwater thruster testing device. Background technique [0002] Underwater thrusters, also known as frogman boosters, are one of the important aids for navy frogmen or diving enthusiasts in shallow sea diving, and are increasingly favored by users abroad. The underwater propeller provides people with a brand new way of entertainment. It improves the range and speed of people's activities in the water. It not only allows people to navigate freely on the water surface, but also brings swimmers into the underwater world for sightseeing, Activities such as expeditions are far more interesting and attractive to people than traditional entertainment activities. [0003] Currently abroad, underwater propellers are very popular and are becoming a common household entertainment tool. In addition to meeting the needs of people's entertainment and life, the underwater thruster project can be s...
