Abstract

A pond and pool surveillance and alarm system is independent from the electric network and may be operated with solar energy or with mains current. The controller is compact, weather-resistant and easy to set up. One or several floats are located on the surface of the water. Each float monitors a 5 m diameter zone. The signalling device with a cable and plug is located in the float. Maximum 3 floats may be connected to the controller. A distributor may also be connected between controller and floats. Another connection is provided for a flash light or siren. Thus with a single in-house cable both acoustic and optical signals may be generated. On large water surfaces, it is recommended to set up a second controller. The object of the invention is to ensure fast warning and thus better safety.

Description

Elektromechanischer Ueberwachungssignalgeber - Schwimmer für ruhige Gewässer.Electromechanical monitoring signal transmitter - float for calm waters.
Mit diesem Schwimmer können Gewässer wie Weier, Schwimmbäder, Teiche, Pools, offene Behälter usw. überwacht werden. Der Schwimm-Körper besteht aus einem runden Unterteil und einem Oberteil. Beide Teile bestehen aus Polyurethan, diese werden nach dem Einbau des Schalters, wasserdicht verschlossen. Der Schalter besteht aus einer Plexiglas-Montageplatte. Auf dieser Platte ist ein Readschalter quer zur Platte montiert. Am anderen Ende der Rechteckplatte in der Mitte der kurzen Seite befindet sich eine feine Bohrung, in der eine feine Feder verankert ist. Diese Feder krümmt sich über den Readschalter und hält das Magnet fest. Die Distanz zwischen Schalter und Magnet wird eingestellt, (mittels Federspannung)This float can be used to monitor waters such as meadows, swimming pools, ponds, pools, open containers, etc. The floating body consists of a round lower part and an upper part. Both parts are made of polyurethane, these are sealed watertight after the switch has been installed. The switch consists of a plexiglass mounting plate. A read switch is mounted across the plate on this plate. At the other end of the rectangular plate in the middle of the short side there is a fine hole in which a fine spring is anchored. This spring bends over the read switch and holds the magnet in place. The distance between the switch and the magnet is set (by means of spring tension)
Am Readschalter werden zwei Drähte verlötet, die aus einem abgeschirmten Kabel herausführen. Das Kabel wird unten aus dem Gehäuse herausgeführt und von innen wasserdicht verschlossen. Die Länge des Kabels wird nach Bedarf zugeschnitten.Two wires are soldered to the read switch, which lead out of a shielded cable. The cable is led out of the bottom of the housing and sealed watertight from the inside. The length of the cable is cut as needed.
Die Arbeitsweise dieses so zusammengebauten Schwimmers ist folgende.The way this float is assembled is as follows.
Bei einer nahezu ruhigen Wasseroberfläche bleibt das am Federende befestigte Magnet nur in geringer Bewegung. Wird das Wasser aber stärker bewegt, zum Beispiel durch ein Gewicht von (ca. 10 kg) in einer Entfernung von ca. 2.5 - 3m, genügen die sich abflachenden Wellen um einen sauberen Kontakt auszulösen.When the surface of the water is almost calm, the magnet attached to the end of the spring only remains in slight movement. If the water is moved more strongly, for example by a weight of (approx. 10 kg) at a distance of approx. 2.5 - 3m, the flattening waves are sufficient to trigger a clean contact.
Durch die auf und ab Bewegung wird das Magnet aus seinem Beharrungs¬ vermögen gelöst und es beginnt unmittelbar zu schwingen, dabei wird der Readkontakt ausgelöst und der Schaltstrom kann fliessen. (Beispiel 12 V / 1.2 A)As a result of the up and down movement, the magnet is released from its persistence and begins to vibrate immediately, the read contact is triggered and the switching current can flow. (Example 12 V / 1.2 A)
So wird nach Anschluss an eine Alarmanlage oder andere Warngeräte ein Alarm ausgelöst. Fig.l Zeigt im Massstab 1:1 einen kompletten Schwimmer.An alarm is triggered after connection to an alarm system or other warning devices. Fig.l shows a complete float on a scale of 1: 1.
Diese Form wurde durch viele Versuche ermittelt um die elektromechanischen Teile aufzunehmen, auch die unterschied¬ liche Länge des Kabels wirkt sich auf die innere als auch äussere Form des Körpers aus. Diese Form verhält εich ausge¬ zeichnet und deshalb erscheint es mir wichtig, dass diese Form (Hohlkörper) geschützt ist.This shape was determined by many tests to accommodate the electromechanical parts, and the different length of the cable also affects the internal and external shape of the body. This shape behaves excellently and therefore it seems important to me that this shape (hollow body) is protected.

Auf dem sich in der Mitte befindlichen Zapfen befindet sich eine Montage¬ platte (4) die, die Elektromechanischen Teile aufnimmt.Fig.3 The cable is inserted through the hole. On the peg located in the middle there is a mounting plate (4) which receives the electromechanical parts.
