Description

The invention relates to the field of fish farming, and in particular to devices that control the process of maintaining the required water temperature when receiving and growing aquatic organisms in closed water supply plants (UZV) and in aquaculture reservoirs.

Installations for maintaining the optimum temperature of water in the ultrasonic testing system are an important tool for growing aquatic organisms, especially in the summer, when the temperature of the water exceeds its nominal fish-breeding value and a device is required that can lower the water temperature and maintain it within specified limits.

Known installations that work to lower the temperature and maintain its value within specified limits.

Such devices are industrial compression refrigeration units operating on a refrigerant (1). The main components of these units are the compressor, evaporator, condenser, thermostatic valve and refrigerant.

The disadvantages of such devices are the complexity of the design, constant monitoring of the personnel over the operation of the cooling device, automatic on / off devices, maintaining the optimal set water temperature, high energy consumption, which leads to a noticeable increase in the price of the final product, as well as the high cost of the device, the complexity of its maintenance requiring specially trained personnel.

The closest in technical essence and the achieved effect (prototype) is the Morozko-3M type ammonia absorption refrigeration unit (2), which includes a heat exchanger, solution collector, hydrogen accumulator, absorber, regenerative gas heat exchanger, reflux condenser, condenser, evaporator, generator, thermosiphon , regenerator, tubes of weak solution, steam outlet pipe, electric heater, thermal insulation.

However, the use of such units in fish farming is very expensive, because requires a lot of electricity.

 The technical task of the present invention is to increase the efficiency of the process of regulation (stabilization) of the water temperature in the ultrasound by using solar energy, which helps to reduce the cost of construction, maintenance and maintenance of the device and a significant increase in the service life of the device.

The task is carried out in that the device contains an absorption ammonia refrigeration unit, it is equipped with a parabola concentrating the sun's rays, with a thermosyphon installed in its focus, which is a heat exchanger of the refrigeration unit, the parabola is mechanically connected to the solar battery, which, in turn, is connected to the battery , a unit for determining the position of the sun and a gear motor that drives a parabola with a solar battery, and the thermosiphon is connected in series with the refrigerator unit and evaporator.

The positive effect is that in automatic mode the water temperature stabilizes; the more aggressive the sun, the more the air in the building cools, maintaining the average night temperature of indoor air, as well as water in the ultrasonic inspection, in the complete absence of electricity consumption from the industrial power grid, and also eliminates the need for control personnel to monitor the operation of the device.

An absorption refrigeration unit, unlike a compressor unit, can use any reported thermal energy, in this case, solar energy, which at the focus of the parabola is more than 300 ° C, which fully ensures its operation.

The set of distinctive features of the described device ensures the achievement of the specified technical result. The design features of the device allow you to stabilize the water temperature in the ultrasound and create favorable zones in fish-breeding ponds while eliminating any energy costs. The circulation of water in a reservoir takes place naturally and ensures the distribution of cold in the water column.

As a result of the analysis of the prior art, no analogue was found that is characterized by features identical to all the essential features of the claimed invention, and the determination of the prototype from the identified analogues made it possible to find a set of distinctive features that are significant in relation to the technical result.

Therefore, the claimed invention meets the condition of "novelty."

A new set of features does not follow explicitly from the existing level of technology and ensures the achievement of a new technical result.

Thus, the claimed invention meets the condition of "inventive step".

Figure 1 shows a block diagram of the proposed device.

The device 1 consists of a solar battery 2, a battery 3, a unit for determining the position of the sun 4, a parabola 5 concentrating the sun's rays, with a thermosyphon 6 installed in its focus on stretch marks, controlled by a reduction motor 7, and a thermosyphon 6 connected in series with the evaporator 8 of the refrigeration unit 9.

The device operates as follows.

Option 1.

When the temperature rises with the sunrise, illuminating the solar battery 2, it recharges the battery 3, which supplies electric power to the sun position detection unit 4, parabola 5, with a thermosyphon 6 installed in its focus on the stretch marks, controlled by a reductive electric motor 7, which receives working electrical power from the battery 3. The air in the room where the ultrasound is located is cooled by the evaporator 8 of the refrigeration unit 9.

When the sun goes down over the horizon, the solar battery 2 stops generating electric power, the reductive electric motor 7, by an electric signal from the sun position determining unit 4, sets the parabola 5 to its initial position. Thus, the higher the temperature of the air heated by the sun, the more intensive the work of the refrigeration unit that stabilizes air temperature in the workshop where the ultrasonic protection device is installed, therefore, the water temperature in the ultrasonic protection device will be supported by the average value of the night temperature, which paradise does not exceed normal fish breeding indicators.

Option 2

The proposed device may be useful for the elimination of deadly hydrobionts when the temperature of the water in fish ponds increases in the summer.

The reason for such killing is a change in the hydrochemical parameters of the reservoir, in particular a change in the pH and O ₂ values in the surface layer of water and at its bottom, which change the electrolytic properties of the reservoir and organic compounds. In this case, the device is installed in a fixed position on the platform in the pond, so that the parabola 5 with the thermosyphon 6 installed in its focus and the solar battery 2 are facing the sun, the sun positioning unit 4 is on the platform, and a reductive electric engine 7, which drives the parabola 5 with the solar battery 2, and the cooling element of the unit 9 - the evaporator 8 was in the water.

With the advent of the sun, the device begins with its cooling element by the evaporator 8, immersed in the water of the reservoir, to cool it, the more actively the sun acts on the parabola 5, and, accordingly, on the thermosyphon 6 of the refrigeration unit, the more water is cooled in the zone of installation of the cooling element. Cooled water is lowered into the bottom part of the reservoir, along the route mixing with pond water and spreading along the bottom of the reservoir, aligning the hydrochemical and organic parameters in the zone of exposure to water with low temperature.

Hydrochemical indicators in this zone are improving, hydrobionts and live food rush to the favorable zone. Its area depends on the capacity of the device or the number of devices installed in the reservoir.

The proposed device can be used in the national economy or in any other areas where there are no power lines, for example, for cooling industrial plant waters, etc.
