Description

The invention relates to methods and installations for providing forced melting of snow mass in the winter season, collected by special vehicles from city streets and roads, and, at the same time, ensuring the operation of the fountain in the summer season. Thus, in the present invention, the authors propose a method of providing snowmelt and a fountain and a universal installation that functions as a snow melter and in the form of a fountain.

Currently, there are a large number of decisions on the design of snow melting installations that ensure the disposal of a huge amount of snow mass in the winter season.

Known, for example, RF patent No. 2173744 from 04/13/2000, disclosing a method and apparatus for forced snow melting. In the aforementioned well-known invention there is a bathtub divided into two compartments, one of which is designed for receiving snow, and the second contains water that is heated with the help of fuel burners, and heated water is taken and fed to the snow mass by a feed system pump.

The compartments are separated by a grid, and the products of the snow melting process are distributed depending on their purpose.

This system serves for the disposal of a significant amount of collected snow, has large dimensions and a complex structure, which leads to the need to have two systems for heating water and air, which complicates the regulation of operation and operation. In addition, certain fuel reserves are required, the combustion of which, among other things, worsens the environmental situation in the installation area.

Fountain installations are widely known, providing in summer comfortable conditions in their locations, able to refresh the air of cities, as well as create various decorative effects that satisfy the aesthetic tastes of residents.

It is known, for example, a fountain device containing an input with a common fluid supply controller connected to the control unit, an accumulation cavity communicating with the tangential channel unit, and an annular outlet for the fluid directed to the symmetry axis of the structure in such a way that a conical surface enveloping the initial the portion of the individual jets flowing from the annular outlet, or the conical surface formed by the initial portion of the merged jets flowing from the annular outlet, is inclined to a horizontal surface ited.

The fountain device may be provided with a housing including an accumulation cavity, an annular transition and a pressure chamber (see RF patent 2147940 from 06.30.99).

However, at present, with the growth of cities, their population and areas, a problem has arisen in the creation of small-sized installations that at the local level ensured the improvement of the district or even large yards, in particular, by removing snow in the winter season and creating a favorable microclimate in the summer. Municipal services need small and cost-effective installations that can be operated in both summer and winter for various purposes.

The objective of the present invention is to provide a method of operating the same installation, functioning in the winter as a snow melter, and in the summertime as a fountain.

The present invention is also the creation of a universal installation that provides melting of collected snow in the winter season and functions as a fountain in the summer.

Another objective of the present invention is the creation of a compact universal installation that provides the above purposes for relatively small areas and volumes.

Another objective of the present invention is to provide a small-sized installation of simple design, convenient in operation and economical in operation, which can be used without investing large financial resources.

To solve these problems, the applicant proposes a method of providing snowmelt and a fountain in one installation, which involves dumping the collected snow into a container with water in it in the winter season, heating this water and supplying heated water to the snow through nozzles, and in summer, turning off the heating water tanks and the supply of this water through nozzles, carrying out the work of the fountain.

In addition, in the specified method, the water supply to the snow and water supply for the operation of the fountain is made through the same nozzles or different nozzles.

Additionally, in the specified method, the water supply to the snow and water supply for the operation of the fountain is carried out using a pump.

In addition, in this method, the heating of the water of the tank is carried out using a heat exchanger, which is placed in the tank or outside the tank.

To solve these problems, the applicant also presented a unit that provides snowmelt in the winter season and works as a fountain in the summer, which includes a tank in communication with a water source and a drain line, a pump installed with the possibility of feeding to the distribution nozzles located in a water tank for snow in a tank when the unit is operating as a snow melter or above the tank when operating as a fountain, and a water heating source installed with the ability to shut off for work From the installation as a fountain with the pump running.

In addition, in the installation, the indicated water heating source is installed behind the pump in one of the branches of the installation line, connected after the heating source to the other branch of the specified line with the formation of a common line connected with the specified distribution nozzles, while in the specified line, one of these branches is blocked with the corresponding opening of another branch, and vice versa.

Additionally, in the installation, the indicated water heating source is installed behind the pump in one of the branches of the installation line associated with the distribution nozzles for supplying water to snow when the unit operates as a snow melter, and the other branch of the indicated line is connected with the distribution nozzles for supplying water to the tank during installation operation in as a fountain, while in the specified highway provides for the overlap of one of these branches with the corresponding opening of another branch, and vice versa.

In addition, in the installation, said water heating source is a heat exchanger and can be installed in said container.

In this installation, a three-way valve is installed at the branching point of the indicated line or a shut-off valve is installed in each of the indicated branches of the line, in one of which this valve is installed before the source of water heating.

Additionally, in the installation of these distribution nozzles are made with the possibility of rotation.

Now, for a better understanding of the essence of the proposed invention, we turn to a detailed description of the claimed with reference to the accompanying drawings.

Figure 1 - shows the installation in accordance with the first embodiment of the present invention.

Figure 2 - shows the installation in accordance with the second embodiment of the present invention.

Figure 3 - presents the installation in accordance with the third embodiment of the present invention.

The drawings show the installation in three preferred embodiments, the operation of which carries out the claimed method of providing snowmelt and a fountain at different times of the year by simply controlling these processes.

Installation 1 is made with the possibility of ensuring its operation in two modes depending on the time of the year, in wintertime as a snow melter, melting the snow collected on the streets and dumped into it, and in the summertime as a fountain.

Installation 1 includes a tank (tank) 2, in which the operating mode is the water supplied from a water source under pressure through a pipe 3 with a valve 4 installed in it, which, after filling the tank to the required volume, blocks this pipeline. Capacity 2 has a line 5 draining excess melt water or water when operating in fountain mode.

In a preferred embodiment (see FIG. 1), the installation 1 has a line 6, to which a pump 7 is connected, which ensures the selection of water from the tank 2. The pump 7 can be immersed and installed directly in the tank 2, or it can be located in the main itself 6, as shown in FIGS. 1-3. Behind the pump 7, the line 6 is directed to the water distribution elements. As such elements, distribution nozzles 8 can be used, which, when the unit 1 is in operation, serves as heated snow melter in the tank 2 to the snow to accelerate its melting, and in the other case spray water over this tank when operating in the fountain mode. In fact, the same nozzles 8 can perform these functions in both winter and summer. These nozzles can always be turned up, as this allows them to supply heated water to the snow in winter, and in the summer to serve as fountain nozzles. At the same time, the end section of the highway 6, on which the nozzles are fixed, or the nozzles themselves, when the function is performed, can be turned to the required angle, for example, in the winter, the nozzle exit 8 is directed down and in the summer up. But it can also be individual nozzles mounted on the parallel end sections of the highway 6, switched using a conventional crane. In installation 1, a source of heating water 9 is provided. Various units, hydraulic or electric, can act as a source of heating 9. In the embodiment shown in FIG. 1, a heat exchanger is shown, along one line of which a heat agent passes, which provides heating of water in a tank 2. In the installation, control and measuring equipment, which is usual for a snow melter or for a fountain, regulates the water level in a tank 2, providing its excess discharge through a drain line 5 that maintains a given temperature of the water and its flow rate through the pump 7, etc., which is not shown in the drawings, but is widely known in the art from these prior art.

In the winter season, the installation works as a snow melter. By special vehicles, snow collected from the streets is dumped into a container 2, in which there is already water with a temperature above 0 ° C, received through pipeline 3 under pressure from a water source. Snow falls on the grate 10, which prevents large contaminants from entering the container 2. Pump 7 delivers water from tank 2 along line 6, and from it to nozzles 8, which spray water from above onto the snow, accelerating its melting, and when the snow interacts with warm water, it melts and excess water is discharged through drain line 5. The heat exchanger 9 provides water heating in the tank 2, supporting the melting mode in the given parameters, and the process control is provided by the above-mentioned instrumentation.

Upon the onset of the warm period of the year, it is necessary to reconfigure unit 1 to operate as a fountain. This installation does not require large labor costs for such a switch. In this embodiment, the container 2 is also filled with water from the pipeline 3 with the tap 4. The operation of the heat exchanger 9 is stopped, which is carried out by any of the known methods, and the pump 7 also supplies the unheated water to the nozzles 8, which spray water over the container as fountain nozzles. Excess water, for example, formed due to heavy rains, is discharged through discharge line 5.

In another preferred embodiment (see FIG. 2), the installation 1 has a line 6, to which a pump 7 is connected, which ensures water is taken from the tank 2. After the pump 7, the line 6 branches out, one of its branches 11 goes to the heating source 9, for example, heat exchanger, and the other branch 12, not reaching the heat source 9, passes to the common line 13. In this embodiment, the heat source 9 is removed from the tank and connected to the pump line. Overhead valves 14 and 15 are installed in branches 11 and 12 after their divergence. Instead of two valves 14 and 15, a three-way valve can be installed, during switching of which the corresponding line opens or closes. The common line 13 is connected at its end section with distribution nozzles 8 of water, which are made in the same way as in the first embodiment.

In the winter season, the installation works as a snow melter. As in the first embodiment of the installation, the pump 7 delivers water from the tank 2 along the line 6. Subsequently, the water is sent along the branch 11 to heat it in the heat exchanger 9, the valve 14 is open and the valve 15 is closed. The water heated in the heat exchanger 9 common line 13 and from it to nozzles 8, which spray water from above onto snow, accelerating its melting. During the entire period of melting snow, the indicated water circulation is carried out with the discharge of its excess through line 5 drain.

When the warm period of the year sets in, the unit 1 is reconfigured to operate as a fountain. In this embodiment, the container 2 is also filled with water from the pipeline 3 with the tap 4. The pump 7 delivers water along the line 6, the tap 14 is closed to turn off the heat exchanger 9, and the tap 15 is opened for water to access the spray nozzles 8 as nozzles of the fountain.

In another preferred embodiment (see FIG. 3), the installation scheme 1 is similar to the second option, only after branching 6 the branches 11 and 12 are not combined, but go to separate nozzles 16 for feeding into the snow and nozzles 17 of the fountain .

It should be noted that this installation does not require any special maintenance. In periods free from operation, tank 2 can be cleaned, lines and units checked, etc., which must be ensured during normal operation of such systems. To improve the appearance, especially in the summer period, the container 2 can be decorated with the corresponding external attributes characteristic of the fountain.

This installation, first of all, can be used to service relatively small areas in the yards of cities, in other areas of local importance and is simple and effective in solving problems of snow removal in the winter and creating comfortable living conditions in the summer.

In this description, preferred embodiments of the method and installation are disclosed, but it should be understood that, without departing from the essence of the invention, it is possible to propose other modifications that are within the scope of the claimed invention.
