Abstract
The utility model relates to stress testing equipment for a net cage model, which relates to the technical field of net cage engineering, aims at solving the technical problem that it is not convenient to use prior stress testing equipment under water, and is capable of collecting stress testing data of the model above the water surface. The stress testing equipment comprises a pulling force tester and a traction steel wire, wherein one end of the traction steel wire is fixed, and the other end of the same is connected with the to-be-tested model; and is characterized in that the traction steel wire which is connected with the to-be-tested model is guided upwards via a bottom guide wheel to be connected with the lower end of the pulling force tester, the traction steel wire connected with the upper end of the pulling force tester is guided by top guide wheels and another bottom guide wheel to be connected with the fixed end of the traction steel wire, the bottom and top guide wheels of the traction steel wire are respectively in guide wheel shaft holes arranged in lower and upper ends of a guide wheel support which is a welded frame, and a support handle is welded on one side of the guide wheel support. The stress testing equipment for the net cage model is used for stress tests for net cages.
Description
Technical field
The utility model relates to the testing apparatus that the cage engineering technical field is used.
Background technology
Dynamometry is in respect of various structural form, and their major part all is crooked resilient steel disc or coil spring.When external force makes elastic steel sheet or spring generation deformation, drive pointer by gear trains such as levers and rotate, pointer is parked in the position on the index dial, is the numerical value of external force.Spring balance is the simplest a kind of of dynamometer.Other dynamometer also has resistance-strain type of dynamometer sensor, piezoelectric type force cell, electronic type force cell etc., and these force cells adopt electron device mostly, are not suitable for measuring in the environment under water.
The force cell of use for laboratory does not possess the characteristic that underwater environment uses, and the collection of underwater environment experimental data is carried out in inconvenience in the fishing gear dynamometer check.
The utility model content
The utility model provides a kind of equipment that stressed measurement data can be gathered at the water surface for having the under water problem of environment use of dynameter inconvenience now.
The technical solution of the utility model adopts tension tester and traction steel wire, traction steel wire one end is fixed, the traction steel wire other end connects tested net cage model, it is characterized in that the traction steel wire that connects tested net cage model connects the tension tester lower end up by a bottom guide wheel guiding, the traction steel wire that connects the tension tester upper end is received the stiff end of traction steel wire through top guide wheel and another bottom guide wheel guiding, the bottom guide wheel of traction steel wire and top guide wheel are contained in respectively the up and down guide wheel boss at two ends of wheel bracket, wheel bracket is the box-shaped body of welding, wheel bracket side welding support handle.
The utility model adopts guide wheel and support to rise on the water surface tension tester, make link that the net cage model tests carry out demonstration and the collection of experimental data to the water surface by this device translates under water, this device structure is simple, reasonable, easily implement, can not change the size of test force, can not affect test result, solve the under water problem of environment use of dynameter.
Description of drawings
What accompanying drawing represented is a kind of schematic diagram of net cage forces testing equipment.
Embodiment
The utility model (see photo) adopts tension tester 1 and traction steel wire 2, and tension tester is connected on the traction steel wire, and traction steel wire is the steel wire of 0.5 millimeter～1 millimeter of diameter.Traction steel wire one end is fixed, and the other end connects tested net cage model.The traction steel wire 6 of tested net cage model connects the tension tester lower end up by bottom guide wheel 5 guiding, and the traction steel wire of tension tester upper end leads through two top guide wheels 7 and the bottom guide wheel of being connected and is connected with traction steel wire stiff end 8.The bottom guide wheel 5 of traction steel wire and top guide wheel 7 are cylindrical roller, cylindrical roller adopts bearing pin to be contained in respectively the guide wheel boss at the up and down two ends of a wheel bracket 4, the box-shaped body that wheel bracket 4 is welded into by galvanized steel plain sheet is apart from the wheel bracket 4 bottoms 100 centimeters welding support handle 3 vertical with wheel bracket.
