preparation example Construction
[0055] A method for preparing a temperature-regulating floating membrane device for aquaculture ponds, comprising the following steps:
[0056] 1) Preparation of reflective film 12:
[0057] After taking the PE film 111 and plating it with aluminum, set the PE coating film 122 on the aluminum layer 121 to make the reflective film 12;
[0058] 2) Preparation of light-absorbing film 11:
[0059] Use a film blowing machine to mix PE plastic particles and carbon black powder, heat, melt, mix and blow into a film;
[0060] 3) Preparation of floating membrane 1:
[0061] Get the light-absorbing film 12 in step 1) and the light-absorbing film 11 in step 2), cut into a rectangle with the same shape and size, face the PE film side of the light-absorbing film 11 after cutting and the light-reflecting film, and heat it at the edge. The welding is connected into a bag shape, and the light-absorbing film 11 and the reflective film 12 are bonded longitudinally by heat welding in the inner ...
specific Embodiment
[0080] spring heats up
[0081] After the pond melts in March in the spring, set the film bag with the light-absorbing film upward according to 1 / 3 of the area, so that the floating film is laid on the water surface, and use the light-absorbing effect of the light-absorbing film to transfer to the water body to heat up the pool water. There is a temperature difference of 1.0°C between the upper and lower layers, and then intermittently turn on the aerator in the pond or the water pump with water stirring effect to mix the high temperature water in the upper layer and the low temperature water in the lower layer convectively to increase the temperature of the pool water, so that the pool water enters the sea cucumber growth room temperature period in advance. After the natural pool water enters the optimum temperature period, put away the film bag for later use.

Abstract
An aquaculture pond temperature adjusting floating membrane device comprises a floating membrane and a fixing device. The floating membrane comprises a light absorption membrane and a light reflectionmembrane. The edge of the light absorption membrane and the edge of the light reflection membrane are hot-welded to form a bag shape. A PE membrane of the light absorption membrane and a PE membraneof the light reflection membrane are opposite, and the edge of the light absorption membrane and the edge of the light reflection membrane are hot-welded and connected to form the bag shape. A plurality of weld joints are formed through the light absorption membrane and the light reflection membrane in an inner cavity of the floating membrane longitudinally through hot-welding and attaching, the inner cavity of the floating membrane is divided into a plurality of channels, and the channels are communicated at the two ends. An outlet communication channel is arranged on the floating membrane, and an openable cover body is arranged on an outlet. Breeding pond water, quaternary phosphonium salt and air are injected into the inner cavity of the floating membrane. Pull rings are arranged on theedges of the two ends of the floating membrane. The fixing device comprises wood piles erected at the two ends of a pond, and the pull rings are bound and fixed to the wood piles through pull ropes.A preparing method includes the following steps of firstly, preparing the light reflection membrane; secondly, preparing the light absorption membrane; thirdly, preparing the floating membrane; fourthly, filling the inner cavity; fifthly, conducting longitudinal fixing; sixthly, conducting transverse fixing. The technical problem that an existing device is not applicable and cannot adjust or control the water temperature can be solved.
Description
technical field [0001] The invention relates to the field of aquaculture, in particular to an aquaculture pond temperature-regulating floating membrane device and a preparation method. Background technique [0002] Water temperature is one of the main factors affecting the life of aquaculture organisms, and providing suitable water temperature is one of the main means to improve the production and efficiency of aquaculture. In recent years, with the abnormal changes in the world's climate, the changes in the water temperature of the aquaculture ponds have also developed in a direction that is not conducive to production, and abnormal high temperatures and continuous low temperatures have occurred from time to time. [0003] Sunlight is the determinant of water body temperature, and the natural reflectance of the water surface is 3-6%, so most of the light entering the water causes the water body to heat up. Most of the methods currently used in production to prevent sunligh...
