Abstract

A system for surface irrigation of crops (Figure 1) is based on the use of an irrigation element (4) that is able to move linearly on its support (16) while being fixed to its water and electricity supply line (1). The movement is ensured by virtue of the winding and unwinding of the strands (1a) and (1b) of the loop formed by the line (1) around a drum (3) with automated rotation (A); (5); (11); (12) and (13). The sealed male/female connectors (8a) and (8b) and the friction contactor (14) and (15) ensure that the element (4) is supplied even when the drum (4) is rotating. The controllers (A); (B); (Cl) and (C2) of the members of the system can be actuated remotely or managed by a computer program (G). The system can operate in a hybrid manner, using electrical energy from the national grid and using electrical energy of solar origin.

Description

Système d'arrosage en surface des cultures  Watering system on the surface of crops
Nous savons actuellement que l'arrosage en surface des cultures se fait à l'aide des techniques d'aspersion d'eau soit à l'aide des canons, des turbines centrifugeuse, des buses montées en série et autres. En dehors de l'arrosage par pivot dont l'arrosage est uniforme, toutes les autres techniques sont généralement montées sur des piquets fixes ou manipulées à la main pour les déplcer d'un endroit à un autre pour continuer l'arrosage, cette opération est contreignante de plus l'arrosage n'est pas uniforme. Quant à l'arrosage par pivot, il demande un budjet assez conséquent pour l'acquisition du matériel, l'installation et l'entretien, de plus il nécessite une préparation du terrain où il sera monté. La présente invention a pour objet de répondre aux besoinx en eau des cultures là où les techniques actuelles présentent des insuffisances. En effet, le nouveau système permet d'arroser tout type de plante en culture, quelque soit la topolographie du terrain (plat, accidenté, stafifié,..) et la superficie de la parcelle. Le système sert à arroser les cultures en champ, cultures sous serre, espaces verts, jadins publics, potagers, plantes en pépinière,...etc. Grâce à cette invention, l'arrosage de toutes ces cultures peut se faire automatiquement et rationnellement en tenant compte de l'économie d'eau et d'énergie. La présente description de l'invention n'est donnée qu'à titre indicatif et non limitatif, elle peut varier selon les formes et les usages. Le système, objet de 1" invention, selon cette version (figure 1), comprend : un tuyau (1) souple armé pouvant conduire de l'eau mais aussi de l'électricité grâce aux conducteurs électriques dont il est équipé (figure 2); un élément d'arrosage (4) est branché en son milieu; un tambour (3) fixé sur un axe tubulaire (6) muni de deux olives sur lesquellles sont branchés, d'une manière isolée, les deux sorties du tuyau (1) situées à l'intérieur du tambour (3); un mécanisme formé d'un moteur électrique (5) d'une courroie (11) et des poulies (12) et (13) assure la rotation du tombour (3) avec son axe (6). Le bobinage du tuyau (1) par ses deux bouts sur le tambour (3) et son passage par la gorge d'une poulie We currently know that the surface watering of crops is done using water spraying techniques using cannons, centrifugal turbines, series-mounted nozzles and others. Apart from pivoting watering with uniform watering, all other techniques are usually mounted on fixed stakes or manipulated by hand to move them from one place to another to continue watering, this operation is counterigning more watering is not uniform. As for the watering by pivot, it requires a budjet enough consequent for the acquisition of the material, the installation and the maintenance, moreover it requires a preparation of the ground where it will be mounted. The present invention aims to meet the needs of water crops where current techniques have shortcomings. Indeed, the new system allows to water any type of crop plant, regardless of the topology of the terrain (flat, rugged, stafified, ..) and the size of the plot. The system is used to irrigate field crops, greenhouse crops, green spaces, public gardens, vegetable gardens, nursery plants, etc. With this invention, the watering of all these crops can be done automatically and rationally taking into account the saving of water and energy. The present description of the invention is only indicative and not limiting, it may vary according to the forms and uses. The system, object of 1 "invention, according to this version (Figure 1), comprises: a flexible hose (1) armed can drive water but also electricity through the electrical conductors which it is equipped (Figure 2) a watering element (4) is connected at its center, a drum (3) fixed on a tubular shaft (6) provided with two olives on which are connected, in an isolated manner, the two pipe outlets (1 ) located inside the drum (3), a mechanism formed of an electric motor (5) of a belt (11) and pulleys (12) and (13) rotates the tombour (3) with its axis (6) The winding of the pipe (1) at both ends on the drum (3) and its passage through the groove of a pulley
(2) lui donnent la forme d'une boucle. Une fois la poulie (2) et le tambour (3) sont éloignés et convenablement fixés par des attaches (Fl) ; (F2) ; (F3) et (F4), la boucle, avec deux brins (la) et (lb), sera tendue. Le bobinage du tuyau (1) sur le tambour (3) est fait de telle manière que lorsque le brin (la) se déroule le brin (lb) s'enroule et inversement, ce qui permet à la boucle de garder la même longueur. Lorsque le tombour(2) give it the shape of a loop. Once the pulley (2) and the drum (3) are distant and properly secured by fasteners (Fl); (F2); (F3) and (F4), the loop, with two strands (la) and (lb), will be stretched. The winding of the pipe (1) on the drum (3) is made in such a way that when the strand (la) unwinds the strand (1b) wraps and vice versa, which allows the loop to keep the same length. When the tombour
(3) tourne dans un sens puis dans l'autre, l'élément d'arrosage (4) décrira la boucle dans les deux sens. Pour permettre à ce dernier de se déplacer linéairement en gardant la même hauteur (18) au dessus sol, on le raccorde, d'une manière coulissante, à un guide (16) tendu sur toute la longueur de la boucle. Pour alimenter électriquement l'élément d'arrosage (4), les conducteurs électriques intégrés dans le tuyau (1), seront d'abord connectés aux bornes (bagues) (14) en passant par l'axe tubulaire (6) du tambour (3) puis à sa boîte de commande (B) à travers un contacteur à friction formé des ballets (15) et des bagues (14). Cette liaison mobile assure le passage du courant électrique dans les conducteurs lorsque l'axe tourne sur lui-même avec le tombour. Quant à l'alimentation du système en eau, elle s'effectue de la manière suivante : l'eau rentre dans l'axe par l'arrivée (6a), parcourt le brin ( la), alimente l'élément d'arrosage (4), repasse par le brin (lb) avant de retourner à l'axe (6) pour se dirige vers le bout (6b). Ainsi l'eau, sous une pression réglée par les électrovannes (9) et (10 ), peut arriver à l'élément d'aspersion (4), pour en sortir, selon le mode d'arrosage choisi, sous formes de jet, de goutelettes, de pluie, de brouillard... etc. Pour brancher le circuit hydrolique du système à la source d'eau on utilise des raccords mâles/femelles mobiles étanches (8a) et (8b) qui permettent à l'eau de passer dans l'axe (6) même quand il tourne sur lui-même. Le type de raccordement mobile du système à la source d'eau et à la source électrique lui permettent de fonctionner normalement soit en mode statique soit en mode dynamique. En mode statique, l'arrosage s'effectue sans déplacement de l'élément d'arrosage (4), comme s'il a été monté sur un piquet fixe, dans ce cas, si la tête d'arrosage est rotative, la surface arrosée sera de forme circulaire et dont le rayon dépendra de la puissance de l'élément d'arrosage (4). Par contre, en mode dynamique, la surface arrosée sera un rectangle accolé à deux demis cercle par ses largeurs (figure 3). En cas de besoin, selon la présente conception, on peut alimenter le système par deux liquides chimiquement différents, un liquide rentre par le bout (6a) et l'autre par le bout (6b) pour être traités, ensemble ou séparément, au niveau de l'élément d'arrosage (4). (3) rotates in one direction then in the other, the watering element (4) will describe the loop in both directions. To allow the latter to move linearly keeping the same height (18) above ground, it is connected in a sliding manner, a guide (16) stretched over the entire length of the loop. To electrically power the sprinkler element (4), the electrical conductors integrated in the pipe (1), will firstly connected to the terminals (rings) (14) passing through the tubular axis (6) of the drum (3) and then to its control box (B) through a friction switch formed by ballets (15) and rings (14). ). This mobile connection ensures the passage of the electric current in the conductors when the axis turns on itself with the tombour. As for the feeding of the water system, it is carried out as follows: the water enters the axis via the inlet (6a), traverses the strand (la), feeds the watering element ( 4), go back by the strand (lb) before returning to the axis (6) to go to the end (6b). Thus the water, under a pressure regulated by the solenoid valves (9) and (10), can reach the spraying element (4), to get out, according to the chosen watering mode, in jet form, droplets, rain, fog, etc. To connect the hydraulic circuit of the system to the water source is used sealed male / female connectors (8a) and (8b) which allow the water to pass in the axis (6) even when it turns on him -even. The type of mobile connection of the system to the water source and the electrical source allows it to function normally either in static mode or in dynamic mode. In static mode, the watering is carried out without moving the watering element (4), as if it were mounted on a fixed stake, in this case, if the watering head is rotating, the surface watered will be circular in shape and whose radius will depend on the power of the watering element (4). On the other hand, in dynamic mode, the watered surface will be a rectangle joined to two half circles by its widths (figure 3). If necessary, according to the present design, the system can be fed by two chemically different liquids, one liquid enters the end (6a) and the other end (6b) to be treated, together or separately, at the of the watering element (4).
