Description

Technical field

The claimed solution relates to insect protection devices for ventilation systems and premises.

State of the art

In the prior art, various devices and methods are known to prevent insects from entering ventilation systems and subsequently into rooms, containers, storages, etc.

The most common way to protect ventilation systems is to install membranes and nets, for example, in the patent of the Russian Federation No. 136541, a wire mesh is used to protect the ventilation system from insects, in the patent of the Russian Federation No. 178462 - mosquito, in the utility model of the Russian Federation No. 167289 a coarse filter is used.

Known methods for protecting ventilation systems by disinfecting the ventilation duct with a disinfectant, for example, RF patent for invention No. 2746574, as a liquid disinfectant, you can use, for example, alkyldimethylbenzylammonium chloride (QAC) diluted with water, polyhexamethylene guanidine hydrochloride (PHMG) or N,N-bis(3 -aminopropyl) dodecylamine; or their mixture in various combinations; or, for example, a mixture based on a complex of two QACs, PHMG with the addition of surfactants, conditioning additives and/or insect repellent additives or the use of pesticides blown by an air stream, as described in the patent of the European Patent Office No. EP0775441. These methods have huge drawbacks - it takes a lot of time to ventilate the room and ventilation systems, it is not safe for humans and animals, and these methods are too expensive.

A known method of treating a room from insects is described in US patent No. US 9226489, including:

increasing the temperature within the sealed volume at a rate of from about 1 to about 15 degrees Fahrenheit per hour until a temperature of at least about 115°F is reached; and

maintaining the temperature at least about 115°F for a predetermined period of time.

Also known is a method for the destruction of pathogenic microorganisms and associated particles in the ventilation system of the building and the ventilation system of the building. This group of inventions relates to the cleaning and disinfection of building ventilation systems, as well as building ventilation systems. The method is characterized by the fact that the ventilation grilles in the ventilated rooms of the building are hermetically sealed and the means of destruction is fed into the air channel of the system under pressure through its lower opening. As a means, a flow of hot ascending air moving under pressure from bottom to top is used, which heats the air channel, parts of the ventilation system and pathogenic microorganisms contained in the air channel to the temperature of decomposition of microorganisms. The decomposition of microorganisms is carried out by drying with hot air and the pressure of an air flow ascending from bottom to top. The process of decomposition of microorganisms and particles is carried out until the moment of transformation of the decomposition product into a safe volatile mixture, which is removed from the air channel by a stream of hot air under pressure from below and suction of the mixture from above. The building ventilation system comprises an air duct with an air intake and an air outlet, with which the air intake fan from the air duct is connected, ventilation windows of the duct closed with grilles, connected with the ventilated premises of the building. The system is equipped with a pressurized hot air blower in communication with the air intake lower opening of the channel into the air channel with closed ventilation grilles, and the system is also equipped with a heat chamber in communication with the fan outlet for receiving decomposition products of microorganisms. EFFECT: group of inventions provides a simplification of the method for the destruction of pathogenic microorganisms and particles associated with them and an increase in the reliability of their destruction.

The disadvantages of this solution is the complexity of the system, its resource, cost, maintainability in general and the complexity of the implementation of the method.

In addition to the listed analogues, there is a huge number of devices and ventilation systems with built-in heating systems for incoming air, the application for patent of the Russian Federation No. 97100149 even describes a device in which the heating system is formed by at least one light bulb, but none of the known systems is directed specifically to eliminate the ingress of insects into ventilation systems.

As described above, despite the variety of designs and methods, there are no economical, safe for life methods and systems for preventing the entry of insects into the premises through ventilation devices.

Therefore, there is a need for a simpler, more effective non-hazardous method and a fire-resistant device for protecting ventilation systems from insect ingress.

Utility Model Disclosure

The technical problem to be solved by the claimed utility model is the creation of a cheap, oversized, effective device for protecting ventilation systems from insects.

The technical result of the claimed utility model is to heat the section of the ventilation system to a certain temperature, thereby creating a thermal barrier impenetrable for insects.

The technical result of the claimed utility model is achieved by the fact that a device is proposed that includes a housing made of a heat-resistant material of a tubular shape, the ends of which are made with the possibility of mounting with tubular elements of the ventilation system, the inner part of the housing in the form of an aluminum alloy cylinder rigidly installed inside the heat-resistant housing, while an aluminum alloy cylinder is connected to a ground wire, a self-regulating heating cable is wound on the surface of the aluminum alloy cylinder with a pitch of 1 mm to 5 mm, fixed with a heat-resistant tape and connected to a wire that can be connected to a voltage source.

The combination of the above essential features leads to the fact that:

the claimed device is much simpler and cheaper than similar ones;

the claimed solution is devoid of the shortcomings of grids, filters, etc., installed in the ventilation, tk. there is no need to rinse and clean the device; dust and insect residues do not settle in it;

the dimensions and design of the device practically do not go beyond the boundaries of the ventilation duct, which simplifies the installation and dismantling of the ventilation system as a whole.

Implementation and implementation examples

Below is an example of a specific implementation of the device, which does not limit the options for its implementation.

The proposed device "Frontier" is intended for installation in the ventilation system of residential, public and industrial premises to prevent the penetration of insects (cockroaches, bedbugs, ants, etc.) from the outside. The efficiency of the device is based on the intolerance of temperatures above 60°C by insects. Given that the temperature inside the device is constantly maintained at about 65°C (±2°C), this is an insurmountable barrier for most insect species.

Specifications

The ambient temperature at which the device is operated must be in the range from +10°С to +50°С, atmospheric humidity not more than 80%, for a short time up to 98% (at an ambient temperature not more than 25°С). Power supply is carried out from the mains of alternating current 220 V and frequency 50 Hz. Power consumption in operating mode is 20 watts. The output to the operating mode occurs 10 minutes after the device is turned on. The initial power consumption can reach 120W. Overall dimensions are 116×120 mm. Weight 360 gr±10 gr. The device does not require any maintenance.

The inventive device according to the figure consists of a tubular body, the ends of which are made with design features for the possibility of mounting with tubular elements of ventilation systems (not shown in the drawings), for example, for a detachable connection through a fitting, coupling, etc. or threaded connections or without the use of the listed , with the implementation of non-detachable connections due to gluing, welding, etc.

The housing (outer part 1) is made of a heat-resistant material that does not support combustion, the inner part 2 is made of aluminum alloy and is an aluminum cylinder rigidly fixed in the shell 1.

A self-regulating heating cable 4 - SRL-16 (or similar) connected to a power supply wire 3 of the PRKS brand (or similar) 2 by 1 mm ( heat-resistant), which in turn is connected to a voltage source (not shown in the drawings) and, if available and necessary, control bodies. Modifications are possible with the installation of a remote temperature sensor, ADC, adapters and batteries.

Part of the housing 2 is connected to the ground wire 5.

Installation and connection

The device is installed in the wall openings of the supply/exhaust ventilation with subsequent sealing of the gaps between the housing and the wall, as well as in round outdoor ventilation ducts with a diameter of at least 100 mm. (Do not use flammable and combustible materials to close the gaps between the mounting hole and the device case) The connection is made by reliable connection of the wires of the device and the power wire according to the color coding: where L is the phase wire (brown, white), PE is the neutral wire (blue, light blue ) and PE - ground wire (yellow-green). Compliance with polarity is not mandatory when connecting the phase and neutral wires. When installing the unit in a ventilation hole in a wall, the minimum depth of the mounting hole must not be less than 220 mm. The device to be installed must not block the vertical part of the shaft. Otherwise, the inflow/outflow of air may be blocked by the body of the product. For installation in an open-mounted ventilation duct, a stepped adapter for the ventilation system and a standard connector for ventilation pipes with a diameter of 100 mm are used.

Implementation example

The device works as follows.

When assembling the air duct, the device is mounted in it by means of connecting nodes, if additional fasteners, glue, sealant, etc. are required. Supply wire 3 is connected to a power source, which can be both battery devices and power generation devices (wind turbines, solar panels, generators on liquid fuel, etc.), or connected to the mains, through power converters, or without the latter.

When the device is turned on, the heating cable 4, fixed with a heat-resistant tape 6 between two layers of the body 1 and 2, heats the inside of the body aluminum cylinder 2, as a result, during the heating process, the internal cavity of the device heats the air entering from the outside to a temperature of at least (65 ± 2) °C, which in turn is an insurmountable barrier for insects.
