Benefits of technology

This patented technology helps prevent damage caused from overheating when treating layers within an underground body of liquid that needs heat. It can be used on both large and smaller types of wellbores without knowing where they are located beforehand. Its technical effect lies in its ability to adjust itself based upon changes in environmental conditions such as temperatures and pressures during operation.

Problems solved by technology

This patents discusses various techniques aimed at reducing or controlling water temperature gradients during sedimentary rock dams due to factors such as soil salinity concentration differences, ground movements caused by tides, and other causes like waves from neighboring areas. These issues affect both physical and biological aspects of coastal environments including damming offshore vegetables, clogging up underground waters with harmful algae growth, causing damage to wildlife habitat structures, and potential threatening human health and food security concerns. Current solutions involve mechanically driven systems and reseral hydroelectric modelling approaches, but each suffers drawbacks associated with its own advantages over others.

Embodiment 1

[0042] Embodiment 1: It is used to improve the intelligent self-regulation device of water temperature stratification in deep water reservoirs, such as figure 1 As shown, the device includes a housing 1 and an underwater locator attached to the housing 1, a depth measuring instrument, a density measuring instrument, a data processor 18 and a variable displacement propulsion device.

[0043] The shell 1 is made of aluminum alloy material, the top of the shell 1 is provided with a pull hook 2, the upper part is ellipsoid streamlined, the middle and lower part is cylindrical, the outer diameter is 1.0m, and the thickness is 0.05m. Smoothly connected, the end is embedded with a solid load-bearing disc 3, which is made of iron and has a density of 7.0×10 3 kg / m 3 , the diameter is 0.9m, and the vertical thickness is 0.25m, which can ensure that the center of gravity of the whole device is at the bottom, and 17 small water-permeable holes with a diameter of 3cm are symmetrically di...

Embodiment 2

[0048] Embodiment 2: Using the device in Embodiment 1 to improve the process of water temperature stratification in deep water reservoirs.

[0049] A reservoir is located in the mid-latitude subtropical zone. When it reaches the normal storage level, the average width of the water surface is 1000m, the longitudinal length is 600km, and the maximum water depth is 120m. It is a typical narrow and deep subtropical reservoir. Stratification occurs in spring and summer and lasts for 2-3 months. Along with the stratification of reservoir water temperature, the water quality in the reservoir area also stratifies. The temperature of the discharged water is lower than the natural water temperature, causing varying degrees of damage to downstream aquatic organisms and crops influences. From top to bottom, stratified reservoirs are thermocline layer, thermocline layer and thermostagnation layer. The thermocline layer is relatively low and is below 40m of the water surface, so it is diffi...

Abstract

The invention discloses a deepwater reservoir water temperature layering intelligent self-adjustment and improvement device and method. The deepwater reservoir water temperature layering intelligent self-adjustment and improvement device comprises a shell, an underwater position indicator, a depth measuring instrument, a density measuring instrument, a data processor and a varactor propelling device, wherein the underwater position indicator, the depth measuring instrument, the density measuring instrument, the data processor and the varactor propelling device are attached to the shell. The upper portion of the shell is in an ellipsoid streamline shape, the middle and lower portions of the shell are cylindrical and in smooth connection with the upper portion of the shell, a solid load bearing disc is embedded in the tail end of the shell, the outer circumference of the solid load bearing disc is sleeved with a swivel, and empennages are fixed to the outer sides of the swivel. The varactor propelling device comprises an air storage tank, a valve controller, a valve, an engine, a varactor propelling cabin, a hydraulic rod and a piston. According to the deepwater reservoir water temperature layering intelligent self-adjustment and improvement device, the position of a thermocline of a reservoir can be automatically determined according to the water body vertical density gradient, then the deepwater reservoir water temperature layering intelligent self-adjustment and improvement device can perform up-and-down reciprocating movement by changing the buoyancy of the deepwater reservoir water temperature layering intelligent self-adjustment and improvement device to promote water bodies above and below the thermocline to be mixed to break the thermocline, the water environment of the layering type reservoir is improved, and the deepwater reservoir water temperature layering intelligent self-adjustment and improvement device has the high practical value in the aspect of treating the water environment of the layering type reservoir.
