Problems solved by technology

However, existing experimenters often use water pressure to discharge crab feces into the breeding pond for feeding. Clean, so it is necessary to measure the flow rate of the water in the culture pond, so as to get the best water pressure value, so it is necessary to develop a flow rate instrument with easy operation and high precision and a method of measuring the flow rate

Embodiment 1

[0032] Embodiment 1 Indoor culture pond 7 with the installation of flow measuring device

[0033] The specific installation steps are as follows:

[0034] 1. To install the bracket 1, the vertical bar 11 and the horizontal bar 12 are first installed in combination with the adjustment member 13, wherein the adjustment member 13 includes a base 131, a movable member 14 that can rotate relative to the base 131, and a movable member that can rotate the movable member 13. Part 14 is fixed on the fastener 15 at a certain rotational position of the base 131, and the end of the vertical rod 11 is installed on the annular hoop 141 protruding outward from the movable part 14, while the movable part 14 is arranged on the annular hoop. The first leg 142 and the second leg 143 on 141, when assembled, the first connecting rod 144 connecting the ends of the first leg 142 and the second leg 143 of the movable part 14 penetrates into the arc groove 132, and the second A leg 142 and the second...

Embodiment 2

[0041] The layout of embodiment 2 indoor culture pond 7

[0042] 1. First, the nozzle 8 that can control the water inlet speed is set on the side wall of the culture pond 7. The nozzle 8 includes a nozzle main body 81, and the nozzle main body 81 is provided with two flow paths that communicate with each other, and all the way is used as a homogenization The first flow passage for farming organisms such as crab feed, and the other as the second flow passage for cleaning up crab excrement, the first flow passage includes a first outlet pipe 82 and a first control valve 83 for controlling the first outlet pipe 82, The second flow channel includes a second outlet pipe 84 perpendicular to the first outlet pipe 82 and a second control valve 85 for controlling the second outlet pipe 84, and the pipe wall of the second outlet pipe 84 is uniformly opened with multiple A spray hole 86, in order to purify seawater better, also can be provided with seawater purifier on the spray pipe mai...

Embodiment 3

[0044] The mensuration of embodiment 3 flow velocity and the adjustment of nozzle 8

[0045] According to the method of embodiment 1 and 2, the test is carried out after the flow measuring device and the indoor culture pond 7 are installed and arranged;

[0046] 1. The test process is as follows: the water temperature is controlled at 25°C, 10 to 20 young crabs are randomly selected and put into the breeding pond 7, and they are adapted for 10 minutes. Then, when it is necessary to sprinkle crab feed to the breeding pond 7, just close the first control valve 83, Open the second control valve 85, the seawater can drive the flow of the culture pond 7 seawater after spraying into the first outlet pipe 82 through the nozzle main body 81, to homogenize the crab feed; when it is necessary to clean up the crab excrement, just close the second control valve Valve 85 opens the first control valve 83, and the water flow is jetted out by the spray hole 86, so that the culture water is ro...

Abstract

The invention relates to a flow measuring device and method of indoor culture pond. The flow measuring device comprises a bracket, a display connected with the bracket, a weight part set on one end of the bracket, and a measuring rod in rotational connection with the other end of the bracket, wherein the end of the measuring rod is provided with an impeller, a light source and a speed sensor. The invention also provides a method for measuring indoor culture pond via the flow measuring device, comprising the steps of arranging indoor culture pond, setting flow measuring device, measuring flow speed and adjusting spray pipe, measuring multiple speed measuring points of each section to measuring position and depth, to make conclusion that different depths of each position do not influence growth and intake of plant, and can clean residual waste bait on pond bottom to adjust spray pipe. Compared with existing technology, the invention is convenient and quick to install, can measure speed of culture demands for culture of organism, and has wide applicable scope.

Description

technical field [0001] The invention relates to the technical field of flow velocity detection, in particular to a flow measuring device and a measuring method for an indoor culture pond. Background technique [0002] Water flow is closely related to the survival, habits, reproduction and growth of aquatic organisms. Studies on the effects of water currents on fish behavior and physiology have shown that fish feeding, clustering, migration, and reproductive behaviors all depend on the swimming ability and movement patterns of fish. Studies have found that fish adopt different metabolic methods in different exercise modes, and fish can obtain enough energy by relying on aerobic metabolism during normal activities. There are few studies on the impact of water flow on the behavior and physiology of crustaceans, such as crabs . [0003] At present, the production methods of crab breeding are becoming more and more diversified, mainly including pond type, fence type, tile urn t...
