Description

The invention relates to the field of urban planning, can be used, in particular, to decorate urban fountains, to install them in squares, squares, parks and gardens and can be used in other areas of national economy in apparatuses and devices where The process technology requires pulsating flows of liquid or gas with a variable (adjustable) amplitude of pulsations.

A fountain is known that contains a pool, fountain nozzles installed in it, a circulating pump unit connected by a water intake line to a pool and a discharge manifold with fountain nozzles, regulating valves. It is equipped with a control system including a fan, a converter rotating speed into an electrical signal, an electric signal into a pneumatic signal converter and a spring-loaded pneumatic valve installed in the discharge manifold 1.

The disadvantage of this fountain is expensive and difficult to manufacture electropneumatic equipment that runs continuously, consumes electricity, and water is saved only on windy days and hours due to some decrease in the height of the jets ejected, leaving the flow rate to be very large.

Also known is the fountain, which is closest to the invention by its technical essence and achieved result and contains a basin, a hydraulic unit connected with a water intake line with a pool and flow lines, a pulsator-distributor with a lower pressure volume and an upper backpressure volume, a control valve and connecting pipelines 2.

The disadvantages of it - the complexity of the design and the inability to quickly install anywhere in a short time.

The purpose of the invention is the expansion of operational capabilities,

This is achieved by the fact that the pool is made of panels and a polyethylene film placed inside, fastened to the panels with a decorative overlay.

In addition, the fountain is equipped with a drain line fitting located in the upper part of the pulsator-distributor for connecting the upper back pressure volume to the control valve.

Fig, 1 shows a fountain, a general view; in fig. 2 - sectional pulsator; in fig. 3 - pulsator distributor rotor; in fig. 4 is a section A-A in FIG. 2; in fig. 5 is a view B in FIG. 2; in fig. 6 shows a variant of assembling a fountain from panels: in FIG. 7 - a variant of placing a fountain on the ground.

The fountain contains a pool made of light, easy-to-assemble and easy-dismount panels 1 and placed inside a plastic film 2 fastened with panels 1 with a decorative overlay 3.

A portable hydraulic unit 4 is located in the center of the basin, connected by a water intake line (not shown) with a pool and supply lines (not shown) with fountain nozzles 5, and assembled from an electrohydraulic pump 6 with a mesh filter 7.

The fountain also contains a pulsator-distributor 8, a drain line 9 for controlling the magnitude of the amplitude of the pulsations, a control valve 10 and connecting pipes (not labeled),

The pulsator-distributor 8 is made with a lower volume of pressure and an upper volume of counterpressure and contains a fitting 12 of a drain line 9 located in the upper part of the housing 11 for connecting the upper volume of the counterpressure to a control valve 10 located, for example, on one of the panels 1 on the fountain control panel 13 where the control of electrohydrrnasos b is also taken,

In the middle part of the housing 11 of the pulsator-distributor 8, the discharge ports 14 are made with internal threads, in the upper part of the housing 11 there is a threaded hole in which the fitting 12 of the drain line 9 is screwed, and inside the housing 11, starting from the discharge ports 14 up to the end the housing 11, made the cone expansion 15 with some small angle of taper. From above, the housing 11 is closed by a lid 16, in the thickened middle part of which a hole 17c is made with an internal thread, which is closed by a plug 18 to the corresponding thread, inside which is fixed a buffer spring 19. Inside the housing 11 of the pulsator-distributor 8 there is a rotor 20 with a certain clearance that allows free axial and the rotational movement of the rotor inside the housing 11,

In the cylindrical body of the rotor 20, for example, two guide cuts 21 are diametrically opposed to each other.

0 Bottom of the rotor 20 are attached, for example, two blades 22. The housing 11 from the bottom is closed by the bottom 23 of a cylindrical shape with two inlet nodes 24, in which are placed, for example, two rail guides 25 attached to the pivot axes 26, and outside to the pivot axis 26, cranked levers 27 are attached, kinematically interconnected in pairs by strips 28 having in the middle part

0 pins 29. In the center of the bottom 23, on the outside, there is an axis 30 on which a gear sector 31 is fitted, having two radial diametrically opposite grooves 32 in which the pins are placed

5 29. The toothed sector 31 engages with an adjusting screw 33 placed in axial bearings.

The portable fountain can be placed and easily mounted anywhere

0 public garden, square, park, kindergarten, in the lobby of a theater or cinema, in a factory’s hot shop or in a factory’s dusty factory, in places of ceremonies and celebrations, in hotel and institutional hallways, on streets and intersections

5 streets with large flows of moving cars, where you can choose an equal free area and temporarily (or constantly) bring electricity. The pool body is assembled from the lungs (wood,

0 plywood, duralumin, plastic and the like) of identical panels 1 by connecting with easily-connected and easily-tangled nodes (hooks, loops, dovetail, or other). In the internal volume

5 of the fountain casing, plastic film 2 is placed, and on top - the film and panels are covered with a decorative overlay 3.

Hydroelectric unit 4 is located in the middle part of the basin, and, for example, an ESP-91B airborne booster pump with a MP-100-2S electric motor of direct current with a voltage of 24 V, current of up to 6 A, and capacity of up to 5,000 can be used as an electrohydropump.

5 l / h The pool is filled with water to the desired level, and the fountain is ready for operation,

The fountain works as follows. When the electrohydraulic pump is turned on, water taken from the pool through the mesh filter 7 enters the electrohydraulic pump 6

and through its injection line goes to two supply units 24 of the pulsator-distributor 8, in which it is twisted with the help of guide pairs of blades 25, and swirls to the rotor 20.

The swirling flow of water, acting on the blades 22 and the lateral surfaces of the guide notches 21, rotates the rotor 20, simultaneously raising it upwards. When the rotor 20 moves upward between the lateral surface of the tapered rubbing 15 and the guide cuts 21, gaps are formed through which water rushes into the counterpressure cavity between the cover 16 and the top surface of the rotor 20. The buffer spring 19 protects the cover 16, attached to the plug 18. The tension of the buffer spring 19 is adjusted by moving the plug 18 along the thread. As the backpressure cavity fills with water (with the control valve 10 closed), the pressure and the backpressure level out, and the rotor 20 under the influence of its own weight and the force of the compressed buffer spring 19 goes down to its working position with the maximum amplitude of the pulsations. When the control valve 10 is fully opened, the water from the backpressure cavity along the drain line 9 is discharged into the basin, the backpressure decreases and the rotor 20 moves upwards under the action of water pressure from below. The amplitude of the pulsations is reduced, and in the upper position of the rotor 20, the pulsation stops and the fountain operates according to the traditional scheme — with a continuous flow of water. Regulating the amount of water discharged by the valve 10, the rotor 20 is installed in any intermediate position, i.e. ensure the flow of water

from fountain nozzles with any amplitude of pulsations.

The intermediate position of the rotor 20 depends on the amount of water being drained (like the position of the float in the rotameter). The speed of rotation of the rotor 20, i.e. the pulsation frequency, is controlled as follows. By rotating the adjusting screw 33, the toothed sector 31 is rotated to either side. The pins 20 located in the slots 32 move the strips 28, which, through the crank levers 27 and the pivoting axes 26, rotate pairs of vanes 25 in a certain direction, causing the incoming water to twist and, acting on the blades 22 and the side surfaces of the guide notches 21, causes the rotor 20 to rotate at an adjustable speed in any direction chosen.

The use of portable fountains in the gassy streets and intersections can significantly improve the ecology of cities.
