Description

Large area water algae cultivation device

Technical field

The utility model specifically relates to a large-area water area algae cultivation device.

Background technique

At present, the cultivation of microalgae is gradually prospering as a means of maintaining and improving human health, beauty, production of important nutrients, growth of livestock and aquatic organisms, and as a carbon fixation method to prevent global warming.

The primary culture of microalgae is usually carried out using an Erlenmeyer flask. Algae liquid (5000CC) is placed in the Erlenmeyer flask and cultured under certain temperature and light conditions. During the cultivation process, the concentration of the algae solution will affect the light transmittance. The closer to the surface of the Erlenmeyer flask, the better the lighting conditions. In order to enable the microalgae in the Erlenmeyer flask to receive light more evenly and to prevent the microalgae from settling, The algae liquid needs to be remixed at certain intervals. The mixing method is mainly by manually shaking the conical flask to redistribute and mix the algae liquid in the conical flask.

In recent years, in the existing technology, incubators and other devices have begun to be used to replace manual operations. The Chinese patent with publication number CN116042394 A discloses a reactor shaking table mechanism and a bioreactor. The shaking table is used to shake the reactor placed on it. Shake the culture bag to improve the culture effect. In the existing technology, this type of device is mostly used for laboratory culture. Its advantage is that it integrates temperature, light, and shaking functions with a high degree of integration. The disadvantage is that it is usually not suitable for large-scale batch culture and uses horizontal methods. Shake and the mixing effect is weak.

Large-scale algae culture usually uses the field culture method, that is, algae are cultured in transparent bags in water or on the water surface. When it is carried out in a bag culture unit with fixed culture bags installed on the sea surface or large lakes, due to the wind direction of the ocean or large lakes, is changeable, and the directions of waves caused by wind are also different, and the way of directly fixing the culture bag causes the culture bag to only rock in the direction set during installation, and when the direction of the waves changes, it cannot be waved It causes shaking and affects the cultivation of algae.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, not all of them. Example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between various components in a specific posture (as shown in the accompanying drawings). The relative position relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

As shown in the figure, the utility model discloses a large-area water area algae cultivation device, which includes a placement slot 4 for placing a plurality of culture bags. The placement slot can be made of metal plates or plastic plates, and its upper end is provided with There is an opening, and the culture bags are arranged side by side in the placement slot one by one. The width of the placement slot generally matches the length of the culture bag. There are a number of parallel brackets arranged above the placement slot. The brackets are directly connected to the placement slot. It can be welded and bolted, so that the two form a whole, and the distance between each floating bag can also be ensured to remain unchanged. Floating bags 1 are provided on both sides of the bracket, and the floating bags are located on both sides of the placement slot. Using the floating bags So that the placement tank can float on the water surface or the sea, the floating bag is fixedly connected to the bracket through a controllable telescopic mechanism 5. The telescopic mechanism can be an electric telescopic rod or a telescopic rod, or it can drive the telescopic rod through the driver 2 (such as a cylinder) Action, the bracket is also equipped with:

Wave sensor, used to detect the wave height and amplitude of water surface waves. The wave sensor can be a commercially available product;

Controller 3 receives the signal output by the wave sensor and outputs a control signal to control the telescopic length of the telescopic mechanism in real time. The controller is set in a sealed box to prevent it from being affected by the ocean or lake environment, especially the seawater corrosion of the ocean. It is set in the sealed box. Inside the box, it can effectively avoid seawater corrosion and extend its service life.

When in use, the wave sensor is used to measure the current waves on the water surface or sea surface in real time, and obtain the wave height, wave period, wave direction and other parameters of the wave, and send the parameters to the controller. The controller controls the wave in real time based on the detected parameters. The telescopic rod changes, thereby changing the length of the telescopic rod, so that it is synchronized with the wavelength, maximizing the use of wave energy. The bracket is arranged vertically in the axis direction of the slot.

The distance between two adjacent brackets is equal to ensure that the distance between each floating bag is equal, so that the buoyancy force received by the circumferential direction of the placement slot is similar, ensuring its overall balance.

At least one anemometer and water surface flow velocity meter 6 are provided in the circumference of the placement slot. They are wirelessly connected to the controller and can be directly set as a buoy. They transmit data to the controller through wireless communication 7.
