Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of experimental instrument brackets, and in particular to a foldable instrument bracket suitable for flume experiments. Background Art
[0002] In view of the complexity and variability of waves in nature, physical experiments are often used to conduct various studies under the action of waves in the laboratory. Wave gauges, current meters, etc. are commonly used instruments for measuring wave height and flow velocity in the laboratory, which can not only help researchers deeply understand the motion law of waves, but also provide important references and bases for the design of ocean engineering. Under strong dynamic action, how to fix the above-mentioned instruments and ensure the measurement accuracy is an important basis for carrying out flume wave experiments.
[0003] There are mainly two forms of existing flume experiment instrument brackets: one is to use a T-shaped structure to fix the experimental instrument, with the upper side of the horizontal bracket resting on the side wall of the flume and the instrument being tied to the vertical bracket. However, if the experimental water depth changes or the measurement point is changed, the bracket needs to be removed and the instrument needs to be retied; the other is to fix the instrument at the bottom of the flume in the form of a seat bottom, but this method has high requirements for the waterproofness of the instrument and will interfere with the propagation of waves in the flume. Therefore, these two brackets have the following problems: (1) Most of the existing brackets are prefabricated according to experimental requirements, so they have poor versatility for flumes of different sizes (height, span, etc.); (2) For flume experiments with frequent water depth adjustment, in order to meet the instrument measurement range, the existing brackets need to re-tie the position of the instrument on the bracket many times, and the steps are cumbersome; (3) The existing flume experiment instrument brackets are not easy to store, occupy a large volume when stored, and are not easy to store. Therefore, the traditional wave gauge bracket has the disadvantages of poor applicability, cumbersome adjustment steps, and not easy to store. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a foldable instrument bracket suitable for flume experiments, which can expand the applicable range of the bracket, improve the measurement efficiency, and is convenient for storage and carrying.
[0005] To solve the above technical problems, the present invention provides a foldable instrument support applicable to flume experiments, comprising: a main crossbar, a secondary crossbar, a fastening bolt, a main vertical bar, a secondary vertical bar, a folding assembly, a clamping assembly and a spring bolt; the secondary crossbar is provided with adjustment holes and is connected to the main crossbar through the fastening bolt. The secondary crossbar slides on the inner wall of the main crossbar through a groove. Both the main vertical bar and the secondary vertical bar are provided with adjustment holes and are connected into one body through the spring bolt. The secondary vertical bar slides on the inner wall of the main vertical bar through a groove. The clamping assembly is fixed to the secondary vertical bar by welding; the folding assembly includes a connecting pipe, a latch, a hinge and a screw. The main crossbar can be inserted into the connecting pipe and is connected to the main vertical bar through the hinge. The main vertical bar can be folded inward by 90 degrees through the hinge to realize the folding and unfolding functions of the support.
[0006] Preferably, the clamping assembly includes a semi-circular clamping plate, an adjustment screw and a sleeve. The sleeve and the semi-circular clamping plate are welded together. The fastening degree of the semi-circular clamping plate for clamping the instrument is adjusted through the adjustment screw to fix the instrument.
[0007] Preferably, the spring bolt includes a limit cap, an outer tube, a spring, a connecting screw hole and a bolt. One end of the outer tube is welded with the limit cap, and the other end is fixed to the middle of the connecting pipe and the bottom of the main vertical bar through the connecting screw hole. The bolt can be locked into the adjustment holes of the main vertical bar and the secondary vertical bar under the elastic force of the spring and the limit cap, realizing the rapid adjustment of the height of the support.
[0008] Preferably, the main crossbar, the secondary crossbar, the main vertical bar and the secondary vertical bar are all stainless steel hollow square tubes; this can reduce the self-weight of the support and effectively prevent the problem of rust during the use of the support.
[0009] Preferably, a latch is welded on the connecting pipe of the folding assembly. When the support is unfolded, the sliding cover on the latch can be buckled on the corresponding tenon of the main crossbar to lock the hinge to unfold at 90 degrees, so that the main crossbar remains horizontal during work.
[0010] Preferably, the inner side of the semi-circular clamping plate of the clamping assembly is made of rubber material to increase the friction when clamping the instrument.
[0011] The beneficial effects of the present invention are as follows: By sliding the secondary vertical bar on the inner wall of the main vertical bar, the present invention avoids the problem that the existing support is not applicable to flumes of different sizes and increases the fixed range of the support on the experimental flume; at the same time, the height of the main vertical bar and the secondary vertical bar can be quickly adjusted through the spring bolt, avoiding the problem that the operation steps of the existing support are relatively cumbersome when the water depth changes; through the folding assembly, the main vertical bar and the main crossbar are connected in the present invention to realize the folding function of the support, avoiding the problem that the existing support is not easy to store.
