Description
Technical Field
[0001] The utility model relates to the field of deep-sea enclosure-type aquaculture, in particular to a pile-net connection test device. Background Art
[0002] When conducting deep-sea enclosure aquaculture, the strength of the pile net is one of the criteria for determining the quality of the aquaculture facilities. The pile net may be impacted by ocean currents at any time, and the direction and magnitude of the impact force of the ocean currents may change at any time. Therefore, the pile net needs to have a high strength to resist the above-mentioned environmental loads.
[0003] In order to verify whether the pile-net connection strength meets the requirements before it is officially put into use, a pile-net connection test is traditionally required. However, the traditional test process is carried out in water, and the pile-net structure needs to be placed in a larger pool and a wave-making machine is set up in the pool to conduct the test by simulating ocean currents. This test method is relatively costly, complicated to operate, and has relatively low work efficiency.
[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention
[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a pile-net connection test device which has simple structure, ingenious design, reasonable layout, small space occupation, low test cost and convenient and quick operation.
[0006] The technical solution of the utility model is: a pile network connection test device, characterized in that: the test device comprises a horizontal frame 1, one end of the horizontal frame 1 is provided with a longitudinal frame 2, a pile network structure 3 to be tested is provided on the longitudinal frame 2, both ends of the horizontal rail 4 of the pile network to be tested are provided with a dynamometer 5, the bottom end of the longitudinal rail 6 is fixedly connected to the bottom edge of the horizontal frame 1 and the longitudinal frame 2, and the top of the longitudinal rail 6 is also provided with a dynamometer 5,
[0007] A support frame 7 is provided on the horizontal frame 1, and a plurality of simulated force-applying mechanisms are provided on the support frame 7 and are evenly spaced in the longitudinal direction.
[0008] The simulated force-applying mechanism includes a motor 8, a working end of the motor 8 is provided with a lead screw 9, the lead screw 9 is rotatably supported on the support frame 7, and is equipped with a nut block 10 with the lead screw 9, the nut block 10 is connected to the bottom end surface of the slide seat 11, and a force-applying rod 12 is provided at the end of the slide seat 11, and the end of the force-applying rod 12 is fixedly connected to the center point of the bow-shaped elastic force strip 13, and both ends of the bow-shaped elastic force strip 13 are hinged with connecting rods 14, and the ends of the two connecting rods 14 are rotatably connected to the slider 15 at the same time, and the slider 15 is slidably connected in the slide groove 16 on the force-applying rod 12, and the slide groove 16 is distributed along the axial direction of the force-applying rod 12, and a top screw 17 is also threadedly connected to the slider 15.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] The pile-net connection test device of this structural form has a simple structure, ingenious design and reasonable layout. Aiming at various problems existing in the working process of the traditional underwater test device, a special structure is designed that can be tested without water. A pile-net structure composed of a longitudinal frame and a net is arranged at one end of the horizontal frame, and force measuring instruments are arranged on the horizontal and longitudinal frames of the net. At the same time, a plurality of simulated force-applying mechanisms distributed at equal intervals in the longitudinal direction are arranged on the horizontal frame. The front ends of these simulated force-applying mechanisms are bow-shaped elastic strips. The force-applying mechanism group composed of these bow-shaped elastic strips can apply pressure to the pile net with different forces, different frequencies and different positions under the control of the motor. Since the bow-shaped elastic strip itself is in the shape of an arc, the relative position relationship between different bow-shaped elastic strips is superimposed, so that the net forms different curved surface deformations, thereby simulating the force of waves and currents under different conditions. It does not need to set up a pool or purchase a wave-making machine, and can only be used in a land environment to carry out simulated underwater force tests, which reduces the test cost and difficulty and has good engineering applicability.
[0011] Therefore, it can be said that this test device has many advantages, is particularly suitable for promotion and application in this field, and has a very broad market prospect. BRIEF DESCRIPTION OF THE DRAWINGS

Figures 1 to 3 As shown: a pile network connection test device, which includes a horizontal frame 1, a longitudinal frame 2 is arranged at one end of the horizontal frame 1, a pile network structure 3 to be tested is arranged on the longitudinal frame 2, both ends of the horizontal rail 4 of the pile network to be tested are provided with a dynamometer 5, the bottom end of the longitudinal rail 6 is fixedly connected to the bottom edge of the horizontal frame 1 and the longitudinal frame 2, and the top of the longitudinal rail 6 is also provided with a dynamometer 5,
[0016] A support frame 7 is provided on the horizontal frame 1, and a plurality of simulated force-applying mechanisms are provided on the support frame 7 and are evenly spaced in the longitudinal direction.
[0017] The simulated force-applying mechanism includes a motor 8, a working end of the motor 8 is provided with a lead screw 9, the lead screw 9 is rotatably supported on the support frame 7, and is equipped with a nut block 10 with the lead screw 9, the nut block 10 is connected to the bottom end surface of the slide seat 11, and a force-applying rod 12 is provided at the end of the slide seat 11, and the end of the force-applying rod 12 is fixedly connected to the center point of the bow-shaped elastic force strip 13, and both ends of the bow-shaped elastic force strip 13 are hinged with connecting rods 14, and the ends of the two connecting rods 14 are rotatably connected to the slider 15 at the same time, and the slider 15 is slidably connected in the slide groove 16 on the force-applying rod 12, and the slide groove 16 is distributed along the axial direction of the force-applying rod 12, and a top screw 17 is also threadedly connected to the slider 15.
[0018] The working process of the pile-net connection test device of the embodiment of the utility model is as follows: first, the pile net structure 3 to be tested is set on the longitudinal frame 2, the two ends of the horizontal wire 4 of the pile net to be tested are connected to the dynamometer 5 fixed on the longitudinal frame 2, and the top of the longitudinal wire 6 is also connected to the dynamometer 5 fixed on the longitudinal frame 2. After all the wires are tightened, the dynamometer 5 is adjusted to zero;
[0019] Then, the simulated force-applying mechanism is started, and the motor in the simulated force-applying mechanism works, driving the lead screw 9 to rotate, thereby driving the nut block 10 and the slide 11 connected to the nut block 10 to move, so that the force-applying rod 12 arranged at the front end of the slide 11 will move in the direction of the pile network to be measured, and the bow-shaped elastic strip 13 at the end of the force-applying rod 12 will contact the pile network to be measured and apply a certain positive pressure, and multiple simulated force-applying mechanisms work together to simulate the force-applying situation of the wave;
[0020] For example, if a pile net structure is planned to be actually constructed in a certain sea area, hydrological data of the sea area is observed in advance, and the hydrological data is converted into hydrological conditions through theoretical calculations. Then, according to the hydrological conditions, the bow-shaped elastic strips 13 in the multiple simulated force-applying mechanisms are set and adjusted to present the corresponding curved surface shape and reciprocating motion frequency in space, so that the test conditions presented by the device match the hydrological conditions of the target sea area.
[0021] In the process of simulating the action of the force-applying mechanism, all the force measuring instruments 5 will send the data generated each time a force is applied to the control system, which will be processed and analyzed by the analysis program in the control system to obtain the relevant data of the pile network structure 3 under test to determine whether the pile network structure 3 under test meets the requirements.
[0022] During the test, the curvature of the bow-shaped elastic strip 13 can be adjusted according to actual needs. The specific process is to loosen the top screw 17 and push the slider 15 to slide in the slide groove 16. During the sliding process of the slider 15, it will push / pull the connecting rod 14 to move, and the other end of the connecting rod 14 will drive the bow-shaped elastic strip 13 to stretch or contract accordingly, thereby changing the curvature of the bow-shaped elastic strip 13. After adjusting appropriately, retighten the top screw 17.
