Description

Antiparasitic collector for installation of wastewater evacuation.

Object of the invention

The present invention relates to a collector, intended to be part of a water evacuation facility residuals, specifically constituting the terminal of the part of the installation corresponding to the user or client, that is to say as connecting element of said particular network to the general network of the public sewer.

The object of the invention is to achieve a antiparasitic collector, which offering optimum performance as such a collecting element, that is to say when it comes to the evacuation of wastewater is referred to, act further as an element antiparasitic, establishing a barrier to cockroaches and any other types of insects, rodents, etc.

The collector offers the dimensions of any conventional collector, so that it can be easily installed in a sewage disposal network, because it dimensionally adjust to standardized measures in this ambit.

Background of the invention

As is known, the public sewer network of any city constitutes a very particular habitat in which different types of insects live, particularly cockroaches, as well like rodents and other animals.

The problem is essentially that these animals, especially cockroaches, easily reach the homes or other buildings connected to said network of sewage system, using the network pipes themselves particularly at times when water does not circulate through same.

So far the solution to this problem is the use of insecticidal poisons, which besides not getting their eradication, it means a environmental pollution, acting these poisons in a way non-selective, that is, affecting other animals that are not harmful to man, such as the species that inhabit the waters to which the waste will finally flow contaminated, despite having been treated in treatment plants, where the decomposition of organic matter is achieved, but not the Elimination of such poisons.

Description of the invention

The antiparasitic collector that the invention proposes to solve the problem fully satisfactorily previously exposed, allowing to achieve results a lot more effective and selective.

For this and more specifically said collector bases its functionality on the death of these parasites by electrocution, establishing at the connection point between the network sewage system and each particular installation that flows into the same, a high electrical voltage, of the order of several thousand volts, so that any parasite of those cited, as per example a cockroach or a mouse, when it passes through the collector He suffers an electric shock that causes his instant death.

Specifically the collector consists of a kind of sleeve fitted with connection necks standardized, sleeve inside which at least one annular electrode, to which the said high voltage is to be applied, powered by a microprocessor, assisted by a source of power and that controls a pulse circuit that, through a transformer, converts the mains voltage first to low voltage (from 12 to 24 V), to provide the device with proper safety, and then at a voltage of the order of 3,500 V in the electrodes, for electrocutation of the parasites.

According to another of the characteristics of the invention, the high voltage annular electrode (s) remain framed by an input ring and an output ring, both grounded, acting as security elements.

The existence of a water presence sensor at the collector inlet, so that the high voltage annular electrode is inoperative while there is a discharge of water in the particular installation, to Avoid unwanted referrals.

The corresponding control unit is housed in a mechanism box, outside the collector itself and duly attached to it, a box in which an ignition switch is also established for commissioning the
apparatus.

In this way an electrical barrier is achieved to the passage of insects and rodents, which practically does not consume energy more than when the download occurs on any of these animals, and with a practically negligible consumption of diodes led that signal both the correct operating situation of the circuit as some fault in it, as well as the high voltage discharges when they occur.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in side elevation and in section to a room, a collector antiparasitic for water evacuation facilities residuals made in accordance with the purpose of this invention.

Figure 2.- Shows the electrical scheme corresponding to the collector of the previous figure.

Preferred Embodiment of the Invention

In view of the figures outlined, and in special figure 1, can be seen as the collector Antiparasitic that is recommended is constituted from a sleeve or manifold itself (1), based on three pieces, an intermediate and cylindrical that corresponds to the own reference (1), and two other extremes (2-2 '), which couple and securely fix the intermediate piece (1) and that constitute strangulations topped in necks (3) of standardized dimensions, for interleaving in the conduction of wastewater in question, all these pieces of PVC being other similar material, defined in the middle area of the collector a widening for the location of at least one annular electrode (4), which will be subject to high voltage, and that at the passage of one of the parasites cited will cause the discharge that causes the death thereof, or at least a rejection that makes its impossible Access to the protected area.

For feeding the electrode (4), the collector incorporates a circuit housed in a mechanism box electrical (5), fixed laterally to the bushing (1) to which access the power supply cable (6), with the voltage of AC 220V network, through a general switch of on (7), thus supplying power to a source of power supply (8) capable of transforming the alternating mains voltage into low continuous voltage, specifically with outputs (9 and 10) respectively at 5 and 12 V.

The 5V output (9) is used to power (9 ') to a microprocessor (10), which controls a circuit of pulses (11) which in turn receive voltage (12) through the output (12 ') of the power supply (8), and converts the 12 V supplied by said source (8), with the collaboration of a transformer (13), in the 3,500 V provided for the electrode (4).

Since the body (1, 2-2 ') of the collector is plastic in nature and consequently is insulating, it is provided that the electrode (4) is framed by two rings grounding (14-14 ').

As a complement to the structure described and upstream with respect to the electrode (4) and the rings of grounding (14-14 '), the collector incorporates a water sensor (15), whose function is to functionally override the system when water circulates through the collector in order to avoid that the electrode discharge (4) occurs due to the electroconductive nature of water.

Well, this sensor (15) supplies information to a conditioner (16), also fed to through the source (8) and acting on the microprocessor (10), so that it causes an inoperative situation for the pulse circuit (11) as long as water is passing through the manifold.

It only remains to indicate the presence of signaling light emitting diodes (17) also fed to at the expense of the orders of the microprocessor (10), one of red color signaling of the existence of a fault in the system, another of green color that indicates that the system operates correctly, and finally a white third, which indicates that it is occurring a high voltage discharge on the electrode (4).
