Embodiment 1

[0041] see Figure 1-6 , a kind of drifting fish eggs monitoring equipment, it comprises the bottom plate 1 that is used to support and install the whole device, the top of the bottom plate 1 is fixed with a double-layer shell 2, and the bottom ends of the bottom plate 1 are equipped with a bottom plate for monitoring the flow rate The flow rate monitoring device; the bottom layer of the double-layer casing 2 is provided with a main infrared photographing device and a backup infrared photographing device, and the middle part of the bottom layer of the double-layer casing 2 is suspended and installed for the main infrared photographing device and the backup infrared photographing device. A glass cover cleaning device for cleaning; the upper layer of the double-layer housing 2 is placed with a flow rate data storage 5 and an infrared photography data storage 9, the top of the double-layer housing 2 is provided with a top shackle 8, and the double Symmetrically arranged side shac...

Embodiment 2

[0052] A method of using a drifting fish egg monitoring device, which comprises the following steps:

[0053] Step1: Float the entire monitoring device on the water surface through the bottom plate 1, fix the position of the entire monitoring device through the fixed rope 30, and fix the shore fixed pile 34 and the recovery rope 33 at the same time;

[0054] Step2: After fixing all the monitoring devices, start the front-end flow velocity measuring instrument 20 and the main infrared micro-camera 28 in the device, and start monitoring the flow velocity of the river section, the number of floating eggs and the number of hatched juveniles;

[0055] Step3: The flow velocity data monitored by a single monitoring are stored in the flow velocity data storage 5 and the infrared photography data storage 9 respectively;

[0056] Step 4: The data monitored by each monitoring device is transmitted to the signal base station on the shore through wireless signals, and then the signal base ...

Embodiment 3

[0059] Using the monitoring device and method to carry out the ecological regulation experiment of cascade reservoirs in the lower reaches of the A River, most floating fish eggs will have a relative specific gravity slightly larger than that of water after they are produced and swelled by water absorption, and they will gradually sink to the bottom of the river bed in a still water environment. It is easy to cause poor development of fish eggs or even death. The monitoring equipment and scheduling method mainly ensure that the flow velocity of the downstream river section of the spawning grounds of fish that lay floating eggs is above 0.27m / s, effectively improving the floating fish eggs in the lower reaches of the A River. hatching rate.

[0060] Therefore, for the fish that lay floating eggs in the main spawning ground areas in the lower reaches of the A River, the spawning grounds, 5 km downstream of the spawning grounds, 10 km downstream of the spawning grounds, 15 km down...

Abstract

The present invention provides the present invention to disclose a rafting fish egg monitoring equipment and the gradient reservoir scheduling method that improves the incubation rate. It includes the bottom plate for supporting and installation of the entire device., The bottom ends of the bottom plate are installed with a flow velocity monitoring device that monitor the flow rate; the bottom layer of the double -layer shell is set with infrared photography devices and spare infrared photography devices.Cleaning the glass cover with infrared photography devices and spare infrared photography devices; the upper layers of the double -layer shell are placed with flow rate data storage and infrared photography data storage.The ring, the side hook ring with symmetrical layout is set on the side wall of the double -layer shell; the internal drainage device is set inside the bottom plate.To solve the problem of dysplasia or even death of drifting fish eggs in the technical background, and increase the incubation rate of drifting fish eggs downstream of the staircase reservoir.

Description

technical field [0001] The invention relates to the field of refined regulation of cascade reservoirs, in particular to a monitoring device for drifting fish eggs and a cascade reservoir scheduling method for improving hatching rate. Background technique [0002] The optimal dispatch of cascade reservoirs is a typical nonlinear, multi-dimensional and strongly constrained engineering problem. With the development of large-scale hydropower resources in recent decades, the operation of cascade reservoirs has had a certain impact on the spawning and reproduction of downstream fish, and the need for spawning and reproduction of fish downstream of the reservoir can be alleviated by adjusting the operating procedures of the reservoir. is the current research hotspot. However, most of the current research on ecological regulation of downstream fish only focuses on stimulating fish to spawn, and little attention is paid to the drifting process of floating eggs produced by fish.
