Field of technology

BACKGROUND OF THE INVENTION The present invention relates to a device for applying corrective agents, in particular compositions for reducing cyanobacterial growth on water surfaces, comprising a water nozzle and an axial pump for propelling a vessel, wherein the water nozzle and axial pump are rotatably mounted on the vessel for directional control of the vessel. provided by an axial pump for generating a water jet in the water nozzle, the apparatus comprising a correction junction supply line.

The prior art

When contaminating water bodies with cyanobacteria, plankton, algae, oil, etc. there is a threat to aquatic animals and at the same time to the health of the users of water bodies, which is increasingly reflected in recreational areas.

Basically, two methods are used to eliminate the contamination of water bodies. One way is to powder water surfaces with correction agents from aircraft, the other way to powder correction agents from vessels.

Airborne dusting is disadvantageous due to the frequent dispersion of the correction agents beyond the water surfaces, which leads both to environmental hazards outside these areas and significantly increases the amount of correction agents required to effectively remove contaminants on the water surfaces and thus substantially increases the cost of the process.

Powdering of correction products from vessels is very time consuming, the whole process is unproductive and it is realistic to apply it only to smaller water bodies.

Therefore, a further method of introducing corrective agents into the affected water surfaces has been proposed, consisting in utilizing the propulsion tract of the vessel, where a correction agent is fed to the affected water stream in a channel with a propulsor, eg an axial pump. . The advantage of this method of introducing the correction jigs into the water is the possibility of relatively accurate introduction of the jig into the affected areas. By using the propulsion tract of the vessel the device is simple, easy to apply and the introduction of the correction jigs is low labor. low energy intensity.

It is an object of the present invention to provide an injection device for applying correction jigs that takes advantage of the prior art and is applicable to multiple types of vessel propulsion.

SUMMARY OF THE INVENTION

The essence of the injection device for the application of the correction jigs according to the invention is that the water nozzle through which the propulsion water jet of the vessel flows is rotatably arranged and the correction junction supply duct flows into the water jet downstream of the propulsor. The inlet duct opens into the water jet in the region of the axis of rotation of the water nozzle, preferably the water nozzle. Alternatively, the inlet duct opens into the water stream downstream of the water nozzle and is attached at its end to a thrust reverser.

The advantage of this injection device for the application of the correction jig is that it can be used in various types of vessel power units and its ability to disperse the correction jig relatively accurately into the affected areas.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a vessel propulsion motor 1 (not shown) which is connected to a propeller 2. The propeller 2 is arranged in the flow channel 3 through which the water flows from the proolus 2 to the water nozzle 4, which is rotatably mounted about the axis 5. By turning the water nozzle 4 about the axis 5, the direction of navigation of the vessel changes. Inlet to the water stream downstream of the propeller 2 is a supply line 7 which preferably opens into a water stream in the region

A correction device, which may be in the form of liquid, granules, powders and the like, is fed and / or sucked in through the supply line 7.

According to FIG. 2, the axis of the propulsion 2 is arranged substantially vertically and the substantially vertical flow channel 3 is connected by a substantially horizontal water nozzle 4. The axis of rotation 5 of the water nozzle 4 is identical to the axis of rotation of the propulsion aggregate of the vessel. this arrangement results in a water jet in the water nozzle 4.

According to FIG. 3, a plurality of water jets 4 are arranged on the vessel, each of which is separately rotatably mounted about the pivot axis 5 and the supply line 7 opens into a water stream passing through each water nozzle 4, in the region of rotation of the water nozzle 4. a duct 7 into the water stream over the entire area of the flow channel 3 downstream of the propeller 2 to the area of rotation of the water nozzle (s) 4.

4 shows a thrust reverser 8 which is arranged around the horizontal axis 6 and which, when it is inclined into the water stream exiting the water nozzle 4, achieves the return of the vessel. The basic position of the thrust reverser 8 when it does not act in the reverse movement function of the vessel is either above the water nozzle 4 or below the water nozzle 4, as shown, for example, in Fig. 2. Depending on its basic position, the supply line 7 of the correction jigs is mounted at its lower end or upper end. By such an arrangement it is possible to vary the place of introduction of the correction jigs into the water jet, and it is dispersed when the thrust reverser 8 is tilted both during forward movement of the vessel, its small rotation and when the vessel reverses when tilted to the vessel's return position.
