Technical Field
The utility model relates to an aquatic livestock motion parameter measuring device, especially a fish preference swimming speed survey device.
Background
Swimming sports are closely related to the survival of fishes, and directly affect the behavior and ecological habits of predation, enemy avoidance, migration and the like. The preferential swimming speed refers to the most common swimming speed of the fish in a water body in a specific environment, and is formed as a result of long-term adaptation of the fish to the living environment. The research of the swimming preference speed is helpful for better understanding the proper habitat of the fishes and can provide reference data for selecting the proper water flow speed for the growth of the cultured fishes, so that the method has important theoretical significance and application value. The traditional measuring device is mostly a long rectangular water channel placed in an inclined mode, a water storage tank is arranged on the lower portion of the water channel, water is transferred to the upper portion of the water channel from the water storage tank through a water pump through a pipeline, and then water flows with different speeds are built in different regions in the water channel. This kind of survey device utilizes the water pump to pass through the pipeline and shifts and drive water, therefore work efficiency is lower relatively, has caused the waste of the energy to a certain extent to need occupy great space, the overall cost is higher, and traditional survey device has the ripple all the time simultaneously in the course of the work, leads to the subject to be difficult to observe. Therefore, there is a need for a new fish preferential swimming speed determination device that can solve the above problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can be swiftly, conveniently measure out survey device of surveyed fish swimming speed automatically.
The technical solution of the utility model is that: a fish swimming preference speed measuring device is characterized in that: survey device include basin 1, be provided with two symmetric distribution's hang plate 2 in the basin 1, all be connected with grid 3 between the both ends of these two hang plate 2, hang plate 2 and grid 3 form the cross section jointly and be trapezoidal test the speed water course, the length of this trapezoidal short end is D1, the length of the long end is D2, highly is H, then has D1: d2: h =1:3:17, and,
with the water course that tests the speed is matched with and is also trapezoidal top transparent cover 4, is provided with many regional boundary lines 5 that are parallel to each other on transparent cover 4, and these regional boundary lines 5 divide transparent cover 4 equally in length direction, and the quantity of regional boundary line is 5-8, still is provided with the water pump 6 that is located the less one end of the water course that tests the speed in basin 1, still is provided with the open interior barrier net 7 in top simultaneously in the water course that tests the speed, the cross-section of interior barrier net 7 is the rectangle, the length of rectangle minor face is D1, and the length on long limit is H the top of the water course that tests the speed is provided with camera 8, water pump 6 and camera 8 are all through control system unified control.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's fish preference swimming speed survey device, its simple structure, design benefit, it is rationally distributed. The traditional measuring device is mostly a long rectangular water channel which is obliquely arranged, and a water pump is adopted to transfer and drive water through a pipeline, so that the mode is large in occupied area and low in working efficiency, and the surface of a water body is always provided with ripples, which brings interference to observation; in order to solve the problems, the utility model provides a trapezoidal water course structure that level was placed to adopt the water pump directly to drive water, promote the water and flow in the water course, place stop device (interior hurdle net) simultaneously in the water course for the home range of restriction experiment fish ensures that whole experimental area has the same cross-sectional area, is provided with transparent cover above the water course with the water surface ripple that disappears, is convenient for observe the swimming action of experiment fish and use the camera to record the video. The device not only greatly reduces the occupied space of the measurement experiment, improves the working efficiency and the accuracy of the measurement result, but also has simple manufacturing process and low manufacturing cost, so that the device has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: the utility model provides a fish preference swimming speed survey device, it includes basin 1, be provided with two symmetric distribution's hang plate 2 in the basin 1, all be connected with grid 3 between the both ends of these two hang plate 2, hang plate 2 and grid 3 form the cross section jointly and be trapezoidal test the speed water course, the length of this trapezoidal short end is D1, the length of the long end is D2, highly be H, then there is D1: d2: h =1:3:17, and,
with the water course that tests the speed is matched with and is also trapezoidal top transparent cover 4, is provided with many regional boundary lines 5 that are parallel to each other on transparent cover 4, and these regional boundary lines 5 divide transparent cover 4 equally in length direction, and the quantity of regional boundary line is 5-8, still is provided with the water pump 6 that is located the less one end of the water course that tests the speed in basin 1, still is provided with the open interior barrier net 7 in top simultaneously in the water course that tests the speed, the cross-section of interior barrier net 7 is the rectangle, the length of rectangle minor face is D1, and the length on long limit is H the top of the water course that tests the speed is provided with camera 8, water pump 6 and camera 8 are all through control system unified control.
The embodiment of the utility model provides a working process as follows: firstly, experimental fish is placed in an inner fence net 7, then a transparent cover body 4 is covered on the top of a speed measuring water channel, so that the inner fence net 7 is closed, a water pump 6 is started, the water pump 6 enables water in a water tank 1 to flow circularly, the flowing direction is from the smaller end of the speed measuring water channel to the larger end, the cross section of the speed measuring water channel is in a long and thin trapezoid shape, the flow velocity of water flow in the speed measuring water channel is gradually reduced along with the gradual increase of the longitudinal section, and areas with different flow velocities are formed in the length direction of the speed measuring water channel, and due to the interception of the inner fence net 7, the experimental fish can only move near the central axis of the speed measuring water channel, so that the whole experimental area (in the inner fence net 7) is ensured to have the same cross section, and the experimental fish is prevented from moving to the area close to an inclined plate 2, and;
in the process, the swimming condition of the experimental fish is shot by using the camera 8, the top of the speed measurement water channel is covered with the transparent cover body 4 (the water level of the water tank 1 in the experimental process is just equal to the transparent cover body 4, so that the ripple generated on the water surface in the experimental process can be effectively reduced), meanwhile, the transparent cover body 4 is marked with the area boundary line 5, after the video picture is recorded, an operator can conveniently calculate the total staying time of the experimental fish in each speed measurement area, under the condition of constant output of the water pump 6, the inclination angles of the two inclined plates 2 are known, the flow speed of water flow in each speed measurement area can be calculated, and the preferred swimming speed of the experimental fish can be calculated according to the total staying time of the experimental fish in each area and the specific flow speed of each area.
