Definitions

  • a head and a pole for a snowmaking machine of the type comprising a body pertaining to the head fixed to the pole of said machine, the head fixed by connection means of the pole, first tubular elements provided within the pole and connected to second tubular elements pertaining to the body, a liquid fluid and an air carried throughout the first tubular elements to second tubular elements and flowing through holes provided on the body to form artificial snow and comprising therefore third tubular elements pertaining to the head that connect the first tubular elements to the second tubular elements and said third tubular elements have: a different inclination with respect to the first tubular elements and to the second tubular elements, a greater inclination than the first tubular elements defining that the second tubular elements are aligned to the vertical axis and a different inclination with respect to each of them.
  • This application falls within the field of the machines for producing artificial snow, especially for ski slopes, in particular the ones that disclose the head.
  • these machines use basically at least one liquid fluid, for example, water and an air so that once they release through the head nozzles or openings, they form the snow outside by the air and water mixture.
  • liquid fluid for example, water and an air
  • European Patent No. 1123479 ( ES2178481 ).
  • Said patent solves the problem of how to avoid ice forming in the chambers of snowmaking machines by reducing the stop necessity for discharge and clean said ice. This is achieved by means of a head inclined with respect to the pole.
  • liquid fluid continues to freeze, with ice forming in the ducts or tubular elements, since not all the liquid fluid is removed from the tubular elements. If all the liquid fluid is not removed from the head, the liquid fluid freezes when said snowmaking machine is not in use, and the ice by expanding ends up cracking the ducts or tubular elements.
  • the problem to be solved by this invention is how to remove completely the liquid fluid from the head to prevent it from freezing and cracking the tubular elements as a result of the outside cold.
  • the inventor has solved the above-mentioned problem by introducing tubular elements between the tubular elements coming from the pole and the tubular elements coming from the head, this way, it gives to the unit an additional inclination which means that if any liquid fluid remains, it falls by gravity into the machine's deposit in the base of the pole, and does not remain in the ducts.
  • An object of this invention is a head and a pole for a snowmaking machine of the type comprising a body pertaining to the head fixed to the pole of said machine, the head fixed by connection means of the pole, first tubular elements provided within the pole and connected to second tubular elements pertaining to the body, a liquid fluid and an air carried throughout the first tubular elements to second tubular elements and flowing through the holes provided on the body to form artificial snow and comprising therefore third tubular elements pertaining to the head that connect the first tubular elements to the second tubular elements and said third tubular elements have: a different inclination with respect to the first tubular elements and to the second tubular elements, a greater inclination than the first tubular elements defining that the second tubular elements are aligned to the vertical axis and a different inclination with respect to each of them.
  • Figure 1 illustrates a head 11 and a pole 2.
  • Figure 2 represents a body 1 of the head 11, the pole 2, connection means 6, first tubular elements 3,4,5, second tubular elements 7,8,9, third tubular elements 13,14,15, holes 10,21,22,23, O-rings 24 and inclined connections 16,17,18.
  • Figure 3 illustrates an intermediate support 20 and the third tubular elements 12, 13, 14,15.
  • Figure 4 illustrates the intermediate support 20 and tubular elements 13, 14,15.
  • Figure 5 illustrates the head 11, the pole 2, first tubular elements 3,4,5 and third tubular elements 13,14,15.
  • the head 11 comprises the body 1 that is attached to the pole 2 pertaining to the machine. Said join is made by connection means 6 of pole 2 already known.
  • first tubular elements 3,4,5 within pole 2 which transport the liquid fluid, in this case the water and the air, to second tubular elements 7,8,9.
  • the hole 10 releases the air, although optionally, as will be explained later, by energy consumption issue will be air with water, and the holes 21, 22, 23, release the water.
  • Second tubular elements 7,8,9 connect to first tubular elements 3,4,5 by means of third tubular elements 13,14,15 that join them, defining a continuous passage from pole 2 to hole 10.
  • Said third tubular elements 13,14,15 are within the head 11, and they are the ones that allow the easy return of the extra water, which has not released through holes 10,21,22,23 preventing it from freezing, and thus first tubular elements 3,4,5 prevent from cracking due to the water freezing and expanding inside first tubular elements 3,4,5.
  • Third tubular elements 13,14,15 have a different inclination with respect to first tubular elements 3,4,5 and second tubular elements 7,8,9. This means that, when the head 11 is situated in the vertical position, second tubular means 7,8,9 are arranged the same, but as third tubular elements 13,14,15 are at an inclination, they help the water to accelerate due to gravity and to fall inside the tubular elements.
  • first tubular elements 3,4,5 the water does not lose said acceleration and continues going down, and does not remain in first tubular means 3,4,5.
  • third tubular elements 13,14,15 have a greater inclination than first tubular elements 3,4,5 defining that second tubular elements 7,8,9 are aligned to the vertical axis, in other words having as a reference that second tubular elements 7, 8, 9 are aligned with the ordinate axis or parallel to it.
  • third tubular elements 13,14,15 have a different inclination with respect to each other in order to facilitate that holes 10,21,22,23 are being in all directions.
  • first tubular elements 3,4,5 are more separated from one another than second tubular elements 7,8,9.
  • connection of second tubular elements 7,8,9 to holes 10,21,22,23 is made by inclined downward connections 16,17,18 with respect to second tubular elements 7,8,9.
  • Said inclined connections 16,17,18 reduce the space of second tubular elements 7,8,9 that connect to holes 10,21,22,23, also reducing the length of the section of second tubular element 7,8,9 when in horizontal position, whereby it is difficult for any water to be retained in said second tubular elements 7,8,9.
  • FIG. 3 and 4 Another manufacturing option would be that shown in Figures 3 and 4 , i.e., arranging an intermediate support 20 belonging to head 11, which houses third tubular elements 13,14,15. Said intermediate support 20 connects the body 1 to the pole 2, and first tubular elements 3,4,5 to third tubular elements 13,14,15 and these ones to second tubular elements 7,8,9.
  • This option makes the unit very versatile as it facilitates the replacement, if necessary, of the damaged or blocked parts.
  • the pole 2 is a hollow tubular element, within which the first tubular elements 3,4,5 are arranged the first tubular elements 3,4,5.
  • These first tubular elements 3,4,5 are made of tubes or hoses for hydraulic use, for example synthetic rubber or polyester, with high-strength steel spirals, etc., this way, if said tube or hose is damaged the operator would only have to change that particular hose or tube, and not pole 2 as happens in some cases until now.
  • the inventor has looked for a formula to reduce compressors consumption.
  • the central one 4,8,14 carries air, while the others three carry water.
  • the inventor has seen that by making water as well as air come out from the central tubular element 4,8,14 the same end product is created and also air compressor consumption is reduced by 50% depending on the temperature.
