[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] It should be noted that the embodiments of the present invention and the features thereof may be combined if there is no conflict.

[0019] The present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0020] Example 1

[0021] Figure 1 FIG. 1 is a schematic diagram of a top view of a multifunctional underwater snake bend test tank provided in an embodiment of the present invention. Figure 1 As shown, the multifunctional underwater snake test tank provided in this embodiment includes a plurality of connecting bend pipes 1 made of light-shielding material (or opaque material) and a plurality of straight pipes 2 made of light-shielding material and arranged at intervals in front and back, the straight pipes are provided with light-transmitting openings 3 and sealing opening covers (not shown in the figure) spirally connected to the straight pipes and used to seal the light-transmitting openings. The straight pipes 2 in the present invention are hollow tube structures with openings at both ends, so the connecting bend pipes 1 can be used to connect the front and rear adjacent straight pipes 2 to form a snake test tank. The two straight pipes 2 (i.e., Figure 1 The open ends of the No. 1 straight-through tube at the top and the No. 4 straight-through tube at the bottom are spirally connected with end covers to use the end covers to close the test tank into a closed system. In the present invention, a first reflector 4 and a second reflector 5 are arranged in the connecting elbow 1, and the angle between the axis line of the front and rear adjacent straight-through tubes 2 and the mirror surface of the corresponding reflector in the corresponding connecting elbow 1 is 45°, so that the light propagating in the direction parallel to the axis line of the straight-through tube 2 can be returned 180° with the help of the reflector and then enter the next straight-through tube 2 in sequence.

[0022] The end cover of the present invention can be made of a light-transmitting material (such as glass), so that the user can cover the end cover with black shading paper of different openings to adjust the light intensity in the test tank; at the same time, the user can also open the sealing cover by screwing it open to adjust the light intensity in the experimental water tank.

[0023] The present invention can meet the testing requirements of the communication device (the communication device to be tested is directly fixed in the straight pipe 2) under static medium (such as water or other medium that can be filled in the test tank) and different light intensities by using the above test tank. The present invention can also replace the medium with different turbidity to test the impact of different turbidity on the performance of the communication device.

[0024] In the present invention, the connecting elbow 1 is used to connect the straight pipe 2 to form a serpentine structure, so as to effectively save floor space and increase the length of the test waterway.

[0025] On the basis of the above technical solution, further, the snake bend test tank provided in this embodiment also includes a circulating water pump 6, and the water inlet and outlet of the above circulating water pump 6 are respectively connected to the two straight pipes 2 relatively located on the outside of the test tank through pipes. In the present invention, the medium flow can be realized in the test tank with the help of the water pump, thereby further meeting the test requirements under a specific flow rate.

[0026] On the basis of the above technical solution, further, the snake bend test tank provided in this embodiment also includes multiple air pumps 7. The air outlet of the air pump 7 in the present invention is connected to the aeration pipe 8 located in the straight pipe 2 through a pipeline, so as to use the air pump 7 and the aeration pipe 8 to explore the influence of the presence of bubbles on the equipment performance (such as the channel).

[0027] Example 2

[0028] The serpentine test trough group provided in this embodiment is actually based on the structure in Example 1, and further utilizes a connecting bend pipe (not shown in the figure, the structure is the same as the connecting bend pipe 1, and the horizontally arranged connecting bend pipe 1 can actually be placed vertically directly) to connect the upper and lower adjacent serpentine test troughs (that is, the serpentine structure formed by connecting the connecting bend pipe 1 and the straight pipe 2 in Example 1) to form a test trough group, and correspondingly, end covers are spirally connected to the ends of the two straight pipes 2 (at this time, the two straight pipes 2 should be located at the diagonal position) relatively located in the middle and outer sides of the test trough group, so as to close the test trough group to form a closed system.

[0029] Compared with the planar test tank structure provided in Example 1, a test tank group with a three-dimensional structure is provided in this embodiment to further reduce the test site.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that any solutions obtained by equivalent substitutions and obvious changes made using the contents of the specification of the present invention should be included in the protection scope of the present invention.
