Description

Equipment for circulating of water.
The invention relates to a device for circulating water, the device being comprised of a floating frame situated on the surface of the water, a wind-rotor, which is arranged to turn supported on its own axle, is attached and situated above it, gearing connected to the axle, a shroud extending downwards from the frame and a mechanism connected to the wind-rotor axle to impel water along the shroud.
In many waterways, such as lakes, ponds, canals, etc there is a problem of a low oxygen content at the bottom of the waterway. The oxygen rich water on the surface and the oxygen deficient water at the bottom are not able to mix together efficiently. The organisms at the bottom consume the oxygen in the water, after which there forms an oxygen free zone at the bottom, where there is no life.
In the waterways are grown different fish, algae, mollusc and other water animals or plants for human nutrition or other useful purposes. In the cultivation of fish, plants and other organisms it is important to keep the oxygen content and/or temperature at the required level where fish and other organisms grow the best.
There are many devices, through the aid of which oxygen rich surface water is transmitted to the bottom of a waterway. In addition there are devices through the aid of which oxygen free or oxygen deficient water is transferred from the bottom upwards, and when it gets to the surface water it becomes quickly oxygenated. With these devices the circulation of water in the waterway is effected and the oxygen content of the waterway is raised. In a certain application wind-power is used as the power source of the device, making oxygenating possible also in situations where electricity is not available. Wind-power can be exploited for this purpose every season of the year. A wind-rotor generally has two or more vanes, which are at right-angles to the surface of the water where the power of the wind-rotor cannot be transferred straight to the device. This affects also the stability of the whole device because through the action of the wind the wind-rotor pushes the frame of the device. The wind-rotors are not generally sufficiently durable in use in the waterway. The present devices have a problem that they do not always withstand hard winds nor do they operate reliably when the waterway freezes. The utilization of wind-power on the water surface in known devices causes problems and expensive service costs also owing to the fact that the pontoons or floats have not been properly designed.
The object of the present invention is to provide a device for the circulation of water with the aid of which the defects connected with the present devices are eliminated. The object of the present invention is particularly to provide a device with the aid of which water can be impelled in the desired direction effectively and reliably. In addition the object of the present invention is to provide a device which is simple in construction, durable and operates reliably in all conditions.
The object of the invention is accomplished with a device which is characterised by what is provided in the claim.
In accordance with the invention the device's wind-rotor is fitted with segment shaped vanes and the outer sides of the frame are sloped from above downwards and outward. The turning direction of this kind of wind-rotor is parallel to the water surface. On the surface of the water there is generally always a breeze, which easily turns the wind-rotor of the present invention. The movement of the wind-rotor can be directly transmitted to the gearing with the aid of an axle and so the axle's torsion point is lowered. Through gearing the motion of the wind-rotor can be transmitted effectively to a impeller element such as a pump and the pump is made to operate even in a slight breeze.
The floating frame or pontoon construction is shaped so that it can withstand a strong wind which causes large waves on the sea, lake or reservoir. Waves normally cause strong rocking of a float or pontoon. In accordance with the present invention, the edges or sides of the pontoon of the device which receive the wind are built so that they receive the waves without essentially rocking the device itself. The edges of the pontoon are beneficially constructed sloping downwards and outward from the upper edge at about 35 - 60° and possibly about 40 - 55° . The achieved advantage is in that the waves when loading the pontoon press it downwards. Thus large waves rise onto and even over the pontoon. The pontoon holds the device very stably also in hard wind. This adds to the operational reliability of the device and ensures the device remains service free. The device is suited to be used for oxygenating water in different waterways and/or for oxygenating water required by plants and animals grown in them.
In a preferred and practical embodiment of the invention, at the upper end of the shroud there is situated a chamber which contains insulation material, and the bearings of the moving parts of the impeller element, which are under water, are situated under the ice level. This protection designed for the impeller element prevents freezing of the moving parts. The bearings of the moving parts of the element, which are under water, are sealed with a water-tight flange which keeps the top part of the impeller element dry. The upper part of the element is filled with insulation material such as polyurethane particles or the equivalent to prevents freezing. This prevents frost from getting into the impeller .parts of the element. The impeller parts do not freeze even in hard frost when there are generally windless periods and the device does not turn at all. To prevent the formation of condensation in the upper part of the impeller element, there is a vent for the circulation of air.
In the following, the present invention is clarified more exactly by referring to the attached drawings: figure 1 represents an application of the device in accordance with the present invention in vertical section view, figure 2 represents the device as in figure 1 in top plan view, figure 3 represents the attachment of the rotors of the device in figure 1, figure 4 represents detail 9 in figure 1, and figure 5 represents another application of the device in accordance with the present invention in vertical section view.
The device according to the drawings comprise frame 1, to which belongs a support and pontoon or other support which floats on the surface of the water, wind-rotor 2 above the surface of the water, wind-rotor axle 3, gearing 4, water transference shroud 5 downwards from the frame, and impeller 6 situated in the water transference shroud. The wind-rotor comprises several approximately segment shaped, or equivalent, vanes 7 and the wind-rotor axle is directly connected to the gearing 4. Here the gearings used are planetary gears which are arranged to control the action of the impeller. The outer edges 8 of the pontoon in the frame are sloped from above downwards and outward at an angle of about 45 -50° . At the upper end of the shroud is formed a chamber 9 in which is placed insulation material and through which passes the axle from the gears to the impeller. The device further includes anchor cables 16 or the equivalent, with which the device is attached to the bottom of the waterway or to some other fixed point.
The vanes 7 of the wind-rotor 2 are attached so that the outer edge of the vane is supported by a metal box-section, or equivalent, shaped to match the circumference of the vane. Box-section construction is extremely light but durable against the strain of wind as well as centrifugal force. The vanes are attached by support arms 11 to the upper end of axle 3 and a certain distance below the support arms further supported by lower support arms 12 and through support structure 13 which rotates around the axle's protective sleeve 14. The support structure includes rollers which are situated inside box 15 as in figure 3. The attachment to the rotor axle is achieved with little support because the support angles are centred about the points of strain. Because of the attachment of the segment shaped vane to the protective sleeve of the rotor axle by way of the lower support and the rollers, only one bearing is needed for the rotor axle. The attachment arrangements are simple and durable, and are not prone to break even in difficult natural conditions. In addition it does not require maintenance.
In the application in figure 5 a diaphragm pump 17 is situated in the upper part of chamber 9. The diaphragm pump takes air from between the pontoons and presses it downwards along one or more tubes, where the air emerges through holes in the bottom part of the casing and is mixed into the water flowing upwards from the shroud and to the sides.
In the application in figure 1 water can be moved with the help of the impeller in either direction along the shroud by turning either the impeller or the rotor in the desired direction. The whole rotor unit can be lifted up and turned over, so that the rotor can turn in the opposite direction. The openings of the shroud 5 are designed to suit the purpose and the upper end is fitted with holes, slits or other openings. When moving water from the surface layer downwards the oxygen rich surface water flows into the shroud through the openings in the top end of the shroud and water is impelled downwards along the shroud until it comes to the end of the shroud where the oxygen rich water mixes with the oxygen deficient water. To the end of the shroud can be fitted one or more directional tubes to one or more sides in order to guide the water in the desired direction.
Correspondingly when moving water from below upwards by the device in figure 5 it flows upwards along the shroud sucked by the impeller and mixes with the surface water when flowing out of the gaps at the upper part of the shroud and oxygenates there.
The invention is not limited to the useful applications presented here, but it can vary within the limits of the inventive idea formulated in the patent claim.
