It is known "Device for converting waste water energy into electrical energy" (RF Patent No. 2492352, IPC (2006.01) F03B 7/00, IPC (2006.01) F03B 13/00, published September 10, 2013) containing a vertical direct-flow channel in the form of a pipe with a hydrogenerator connected to the load in the lower part, in which the screw of the hydrogenerator with blades is located.

There is a control system that accumulates and redistributes the energy received. The invention is aimed at improving operational reliability and ensuring stable operation.

A disadvantage of the known device is the design complexity, which reduces the efficiency of its use in home water supply networks.

The closest in technical essence and the achieved technical result and selected as a prototype is the power generating device described in the article "HPP in the crane" (Journal "Inventor and rationalizer", No. 9, 2008, S. 27), including the housing, made in the form of a small cylindrical nozzle for a crane, inside of which there is a dynamo operating from a tiny hydraulic turbine rotated by a stream of water flowing from a crane. On the body of the device there are LEDs that brightly illuminate the space under the tap.

Thus, it can be stated that the prototype contains a housing, a hydraulic turbine, a dynamo and a load in the form of LEDs, and the mechanical rotation of the hydraulic turbine shaft under the influence of flowing water pressure is transmitted to the dynamo shaft, and its rotation leads to the generation of electric current supplied to the LEDs, so LEDs light up.

The term "dynamo" (according to the prototype) is obsolete, so it is replaced by the modern term "electric generator".

The disadvantage of the prototype is the low efficiency of the device, because the generation of electric current occurs only while using a particular crane, with an electric generating device installed on it.

However, in the home network there are still not only other taps, but also other cold water receivers, for example toilets, boilers, washing and dishwashers, the water flow in which significantly exceeds the water flow in the apartment through a specific faucet.

The objective of this utility model is to develop a new design of an electric generating device with the achievement of a technical result - increasing the efficiency of converting the magnitude of the pressure of the water in the network into electrical energy.

The task is realized by the fact that in the "Power Generating Device", which includes a casing, a hydraulic turbine and an electric generator, two chambers are located in the casing - a sealed and a generating chamber, between which there is a removable sealed partition, and the hydraulic turbine is made in the form of an impeller located inside the sealed chamber, and the generator located in the generator chamber, while the impeller is connected to the electric generator using the leading and driven half-couplings, made in the form of disks, with rigidly mounted on x magnets, in addition, the leading coupling half is rigidly connected to the impeller, and the driven coupling coupling is located in the generator chamber and is connected by transmission to the shaft of the generator, the output of which is connected to the electric load, in addition, at least one samarium is fastened to each coupling coupling a cobalt or neodymium magnet, while the magnets on the two coupling halves are opposite and opposite poles towards each other, the driving coupling half is made in one piece with the impeller, and the casing, the impeller, the magnetic coupling, the removable partition and both chambers - tight and generating - are made of non-ferromagnetic metal - brass, bronze, copper, aluminum or plastic, while the driven coupling half is connected to the generator shaft using a gear made in the form of two gears - a drive and a follower, while the drive gear has a fixed connection with the driven half coupling or is integral with it, and the driven gear has a fixed connection with the shaft of the generator, and the electrical load is made in the form of accumulate I or a consumer of electricity, and an electric machine is designed as a direct current, the electrical energy store is designed as a battery or power generator configured as alternating current machine, wherein the electrical energy store is designed as a rectifier and the storage battery.

The essential features of the claimed device that match the prototype are the following features:

- the output of the generator is connected to an electrical load.

Private distinctive from the prototype of the essential features of the claimed device are the following features:

- the leading coupling half is made in one piece with the impeller;

- the case, the impeller, the magnetic coupling, the removable partition and both chambers - tight and generating - are made of non-ferromagnetic metal - brass, bronze, copper, aluminum or plastic;

- the electric generator is made in the form of an alternating current machine, while the electrical energy storage device is made in the form of a rectifier and a battery.

Between the essential distinguishing features of the claimed technical solution and the technical result achieved with their help - to increase the efficiency of converting the magnitude of the pressure of the water in the network into electrical energy - there is the following causal relationship.

Indeed, the new design of the power generating device allows you to install it by inserting it into an existing home water supply network, for example, after a cold water meter. Moreover, any consumption of cold water leads to the rotation of the impeller and the generation of electric energy, it is clear that the total amount of cold water consumed in the house is several times greater than the amount of water from a particular tap, which makes it possible to achieve the claimed technical result - to increase the efficiency of conversion of water pressure on the network into electrical energy.

At the same time, the presence of a generator chamber with an electric generator in the claimed device makes it possible to convert the impeller rotation (under the influence of the pressure of water flowing through the sealed chamber) into electric current energy and store it in the battery or supply an active inertial load directly, and the presence of a magnetic coupling allows transmitting torque from the impeller shaft to the generator shaft through a removable partition, which eliminates water leakage from the sealed chamber, which is especially important for household appliances.

The implementation of the leading and driven coupling halves in the form of disks with magnets rigidly mounted on them allows maximum use of the spatial resource for spacing the magnets to the greatest distance from the axes of the coupling halves, which ensures the transmission of large torque, and this, in turn, ensures reliable operation of the generator under load.

The leading coupling half can be made in the form of a separate part, which is rigidly connected with the impeller, or can be made in one piece with the impeller.

At least one samarium-cobalt or neodymium magnet is mounted on each of the half-couplings, which ensures high “power” characteristics of the magnetic coupling as a whole, and the location of the magnets on the two coupling halves opposite and with opposite poles towards each other ensures the magnetic coupling is working impeller speed and low impedance load at the terminals of the electric generator.

The implementation of the housing, the impeller, the magnetic coupling, the removable partition and both chambers - sealed and generating - of non-ferromagnetic metal, for example brass, bronze, copper, aluminum, or plastic, ensures reliable operation of the entire device as a whole and the magnetic coupling in particular.

The transmission, kinematically connecting the driven half coupling with the shaft of the generator, in the form of two gears - the driving and driven, allows you to increase the speed of the shaft of the generator, which greatly enhances the output energy characteristics of the whole device.

The generator can be made in the form of a direct current machine, while the energy storage device is made in the form of a rechargeable battery, or in the form of an alternating current machine, while the energy storage device is made in the form of a rectifier and a battery - this allows you to optimize a specific version of the claimed device, based on the nomenclature manufactured products and specified energy parameters.

The inventive device can be used in a domestic water supply network both at the entrance to the house, and in each apartment, office, industrial premises.

Of particular importance is the use of the inventive device in the Smart Home system, for example, complete with security, emergency and fire alarms.

The analysis of the prior art by the applicant, which includes a search by patent and scientific and technical sources of information, with the identification of sources containing information about analogues of the claimed technical solution, allows us to establish that the applicant has not identified analogues that are characterized by the totality of features identical to all the essential features of the claimed devices specified in the utility model formula.

Therefore, it can be argued that the utility model meets the condition of patentability by the criterion of "novelty."

In addition, the utility model is industrially applicable, because the claimed technical solution allows it to be used in the development and manufacture of electric generating and energy-saving devices.

The possibility of implementing the inventive utility model is confirmed by the following description of its practical implementation and is illustrated by drawings.

In FIG. 1 shows the inventive device (section, side view), in FIG. 2 shows a sealed chamber with an impeller (section, bottom view).

The inventive energy-saving device includes a housing 1 with nozzles 2, made in the form of a sealed chamber 3, an impeller 4 and a magnetic coupling 5, consisting of two coupling halves - leading 6 and driven 7.

The sealed chamber 3 has a removable partition 8, and the leading coupling half 6 is located in the sealed chamber 3.

A generator chamber 9 with an electric generator 10 is attached to the housing 1.

The leading 6 and the driven 7 of the coupling half are made in the form of disks, with magnets 11 rigidly mounted on them.

The driven coupling half 7 is located in the generator chamber 9 and is connected by a transmission 12 to the shaft 13 of at least one electric generator 10.

The leading coupling half 6 is rigidly connected with the impeller 4 or is made in one piece with it.

The generator 10 is connected to a drive or energy consumer (conventionally not shown).

At least one samarium-cobalt or neodymium magnet 11 is fixed on each of the coupling halves 6 and 7, while the magnets on the two coupling halves 6 and 7 are opposite and opposite poles facing each other.

The housing 1, the impeller 4, the magnetic coupling 5, the removable baffle 8, and both chambers — tight 3 and generator 9 — are made of non-ferromagnetic metal, for example, brass, bronze, copper, aluminum, or plastic.

The driven coupling half 7 is connected to the shaft 13 of the electric generator 10 by means of a transmission 12 made in the form of two gears - the driving gear 14 and the driven gear 15, while the driving gear 14 of the transmission 12 is fixedly connected to the driven coupling half 7 or is integral with it, and the driven gear 15 transmission 12 has a fixed connection with the shaft 13 of the generator 10.

The generator 10 can be made in the form of a DC machine, while the energy storage device is made in the form of a battery (not shown conditionally) or in the form of an AC machine, while the energy storage device is made in the form of a rectifier and a battery (not shown conditionally).

The inventive device operates as follows.

When water passes under a pressure of 2-6 atm through the nozzles 2 of the hermetic chamber 3, the impeller 4 rotates and drives the leading coupling half 6 of the magnetic coupling 5.

The leading coupling half 6 of the magnetic coupling 5, in turn, due to the interaction of the magnets 11 located on both coupling halves - the driving 6 and the driven 7 - transfers the torque to the driven coupling half 7 of the magnetic coupling 5.

The driven half-coupling 7 with the help of the pinion gear 14, which is fixedly mounted on the driven half-coupling 7 or is made integral with it, transmits torque power to the driven gear 15 of the transmission 12, and since the driven gear 15 has a fixed connection with the shaft 13 of the electric generator 10, then not only the torque from the leading coupling half 6 is transmitted to the shaft 13 of the electric generator, but the rotation speed of the shaft 13 of the electric generator 10 is also increased, because the driven gear 15 has a significantly smaller number of teeth than the driving gear 14.

Due to the rotation of the shaft 13 of the electric generator 10, an electrical voltage appears at the terminals of the latter, which is used to charge an energy storage device (battery) or directly to power a load, preferably ohmic and inertial, for example, to supply a heating element (water heating).

As an option (with appropriate refinement of the design), the inventive device can also be used in gas house networks.

Based on the foregoing, we can conclude that the task posed in this utility model is the development of a new design of an energy-saving device that has achieved the technical result — increasing the efficiency of converting the magnitude of the pressure of the water in the network into electrical energy.
