Description

The claimed technical solution relates to devices structurally associated with the roof, specifically to the bracket for mounting the roof sensor for DEVIreg 850.

During the operation of the roof sensor for DEVIreg 850 [https://devi.danfoss.com/england/catalogue/thermostats/devireg-850/140f1086-devireg-850/] a number of problems occur that have not been resolved as of the date of filing this application.

So, when the sensor is installed in a gutter or on a roof without a bracket, it is completely covered with a snowdrift during snowfall, an ice crust forms, as a result of which precipitation does not fall on the sensor sensors. At the same time, the heating system, when working with precipitation, functions with less accuracy, efficiency, and economy, up to the complete cessation of operation. In the claimed technical solution, the platform for mounting the sensor is made individually for the sensor area, as a result, the sensor body is not completely covered with a snowdrift, an ice crust does not form, and precipitation occurs only on the sensor sensor surface, respectively, the heating system operates with greater accuracy when working with precipitation. , efficiency and economy.

In addition, when installing known sensors, it is often not possible to smoothly lay the sensor cable through a wall or a dormer window due to its placement on brackets that cannot be mounted through a building wall. At the same time, it is not always possible to find a place accessible for precipitation to fall on the sensor due to the protruding edges of the roofs. The claimed bracket is mounted through vertical structural elements (for example, through the wall of a building) in a place accessible to precipitation on the sensor, as well as for maintenance and diagnostics during operation.

The problem of known brackets is also laying the sensor cable in an open form, which can lead to damage to the insulation. In the claimed bracket, the sensor cable is laid in a sealed pipe-holder.

From the prior art studied by the applicant, analogues in design and purpose have been identified.

Thus, the designs of brackets are known according to patents for industrial designs, for example: according to the patent of the Russian Federation No. 67278 "Bracket", the patent of the Russian Federation No. 93938 "Bracket for the shelf".

The disadvantages of the known technical solutions are the difficulty of installing a roof sensor for DEVIreg 850 on them due to a configuration mismatch, the impossibility of internally laying the sensor cable to protect it from dust and moisture.

From the studied prior art, brackets were identified, which are analogues in design.

So, the following brackets are known (see Fig.1):

- Fig. 1a

The disadvantages of the known technical solutions is the difficulty of installing a roof sensor for DEVIreg 850 on them due to a configuration mismatch, for example, the absence of an individual platform; the impossibility of internal laying of the sensor cable for protection against dust, moisture, and also for connection with the indoor temperature controller due to the lack of a holding pipe made in the wall of the building.

Brackets are known from the prior art with the possibility of placing a cable in a holding pipe, for example:

[https://mebeltak.ru/products_pictures/cache/data/tvtumbi/Ultimate/consolw50_1-500x500.jpg].

The disadvantage of the known technical solution is the lack of tightness of the holding pipe, which in the case of outdoor installation will lead to the ingress of dust and moisture into the room.

Devices and methods for installing roof sensors of various brands are known.

So, the design for mounting the ETOR-55 humidity sensor is known [https://asp-klimat.ru/540-3-2-1-1-1-1-1-1-1-1-1-1-1/ ], which is mounted in a gutter or downpipe.

Known "Instructions for the operation and installation of the humidity sensor ESD 524 003" [https://antiledgroup.ru/storage/app/media/uploaded-files/inst-esd-524-003.pdf]. The sensor is mounted in the roof gutter between the heating wires, without touching them, and fixed with a clamp or glued.

Known "Installation instructions for DEVIreg 850 II "Snow and ice melting system for soil or antifreeze protection system for roof drains (1-4 sensors)" [https://shop220.ru/pdf/?id=1070]. The essence is the installation of the sensor by securely fastening to the surface of the gutter/roof/bracket, while the bracket is made in the form of a plate with curved edges.

Technical solutions for installing moisture sensors in gutters are known, for example:

- https://naberezhnyechelny.tuzlist.ru/files/images/product/medium_image/75/746766/obogrev-samoregulirujuschij-kabel-dlja-krysh-krovli_5b6c440155f4e.jpg],

- [https://absteplo.ru/image/data/SRH%20cable/1498_209.jpg],

- [https://domikelectrica.ru/montazh-obogreva-krovli-i-vodostokov/].

In known technical solutions, the sensors are mounted directly on the chute or a flat plate attached to the chute.

There is a known system for installing a sensor on a bracket in the form of a plate with curved edges [https://inglab.ru/wp-content/uploads/2016/08/sxemka-intibledenitelya.png].

The disadvantages of the above known technical solutions for installing sensors of various brands are:

- danger of accumulation of snowdrift and ice crust around the sensor due to the mounting of the sensors directly in the gutters or downpipe without an appropriate individual platform for the sensor;

- less technologically advanced connection of the sensor cable to the thermostat inside the building due to the lack of a holding pipe made in the wall of the building;

- lack of protection of the cable from dust, moisture due to the fixation of the sensor cable in open space, which, in turn, can lead to damage to the insulation;

- less reliable fastening of the bracket to the building structures due to the absence of a plate for rigid fastening;

- greater risk of dust and moisture penetration into the holding pipe and into the building due to the absence of a gland for entering the sensor cable, which (gland) ensures the tightness of the outer part of the holding pipe.

According to the results of the study of the prior art, it can be concluded that the claimed technical solution coincides with various analogues in terms of individual features, as a result of which the prototype has not been identified and the claims have been drawn up without a restrictive part.

The technical result of the claimed technical solution is the development of a bracket for mounting the roof sensor for DEVIreg 850, eliminating the disadvantages of analogues, namely, reaching:

- no danger of accumulation of snowdrift and ice crust around the sensor due to the presence of an individual platform for the sensor;

- more technologically advanced connection of the sensor cable to the thermostat inside the building due to the presence of a holding pipe made in the wall of the building;

- protection of the sensor cable from dust, moisture due to cable fastening in a sealed tube-holder, which, in turn, protects against damage to the insulation;

- reliable fastening of the bracket to the building structures due to the presence of a plate for rigid fastening;

- no danger of dust and moisture penetration into the holding pipe and into the building due to the presence of a gland for entering the sensor cable, which (gland) ensures the tightness of the outer part of the holding pipe.

The essence of the claimed technical solution is a bracket for mounting the roof sensor for DEVIreg 850 to the wall of a building, characterized in that it includes a holder pipe for laying the sensor cable, consisting of an inner part built into the wall and having a length equal to the thickness of the wall, and an outer part with up-curved end, to which is attached a platform with holes for mounting and installing the sensor on it, while the length of the outer part of the pipe-holder is equal to the distance from the wall to the edge of the roof plus at least 100 mm, in the upper bent part of the pipe-holder there is a branch with a thread with a gland providing a hermetic cable entry into the holding pipe, a plate with a central hole equal to the outer diameter of the holding pipe and fixing holes located at the corners of the plate for fixing the pipe is installed on the holding pipe in the transition zone from its inner part to the outside holder to the wall.

Further, the applicant provides a description of the claimed technical solution.

The claimed technical result is achieved by the development of a bracket for mounting the roof sensor for DEVIreg 850 (hereinafter referred to as the sensor).

The claimed bracket consists of the following elements (Figure 2):

- platforms 1 for installation of the sensor 2,

- holding pipes 4,

- plates for fastening the bracket 6,

- gland (cable entry) 9 (hereinafter - gland) - a sealing device used in joints to seal gaps between parts.

The platform 1 for installing the sensor 2 is made individually according to the shape of the sensor 2 (see Fig.4) and contains holes 3 for mounting the sensor 2. The applicant explains that the sensor 2 has an elongated rectangular shape with three lugs for mounting - two on the sides and one in end face, so platform 1 has protrusions on the sides for attaching side lugs, and is longer than sensor 2 by the size of the end lug.

Pipe-holder 4 at the end of the outer part is bent upwards and connected to platform 1 for installing the sensor; in this case, the length of the holding pipe L is equal to the sum of L1 - the length of the outer part of the holding pipe, equal to the distance from the wall to the edge of the roof plus at least 100 mm (for unhindered precipitation on the sensor) and L2 - the length of the inner part of the holding pipe, equal to the thickness the wall into which the bracket is mounted (L = L1 + L2). On the upper bent part of the pipe-holder 4 (under the platform 1) there is a branch with a thread 10, equal to the size of the stuffing box 9, with the possibility of laying inside the pipe-holder 4 of the sensor cable 5 (which is further connected to the thermostat inside the building - not shown in Fig.) .

The plate for fastening the bracket 6 is made with a hole 7 in the center, with a diameter equal to the outer diameter of the pipe-holder 4, with holes 8 at the corners of the plate 6 for fastening to the wall of the building, while the plate 6 is made with sides L3 of variable size, depending on the location its unobstructed fastening and the length of the outer part of the pipe-holder L1, and the larger L1, the larger L3 to ensure the stability of the bracket. The plate 6 is attached to the pipe-holder 4 along its cross section at the intersection of the outer and inner parts of the pipe-holder 4, that is, at a distance L1 from the site 1, equal to the distance from the wall to the edge of the roof plus at least 100 mm and at a distance L2 from the inner edge of the pipe-holder 4, equal to the thickness of the wall.

The gland (cable entry) 9 is connected to the holding pipe 4 through a threaded outlet 10 with the possibility of ensuring a tight entry of the sensor cable 5 into the holding pipe 4 (in order to ensure protection against the penetration of dust and moisture into the holding pipe 4 and into the building).

Assembly of the claimed bracket is carried out as follows.

1. Make a platform 1 for installing the sensor 2, for example, from a steel sheet with a thickness of, for example, 3 mm. The size of the platform is made individually according to the dimensions of the roof sensor for DEVIreg 850: for example, with a sensor surface size of 24 × 216 mm, the platform is made longer by the size of the end ear, for example, 25 × 225 mm in size, while the platform is made with lateral protrusions for attaching the side ears. In the side protrusions and at the end of the platform 1, holes 3 are made, for example, with a diameter of 2 mm, for attaching the sensor 2, for example, with a screw connection.

2. A pipe-holder 4 is made, which is made from the mounting side of the platform 1 bent upwards, for example, by successive welding between the horizontal and vertical sections of the pipe of two bends of steel steeply bent 45°. As a holding pipe, for example, a steel water and gas pipe d20 GOST 3262-75 is used.

The length L of the holding pipe is made equal to the sum of L1 - the length of the outer part of the holding pipe, equal to the distance from the wall to the edge of the roof plus at least 100 mm (for unhindered precipitation on the sensor) and L2 - the length of the inner part of the holding pipe, equal to the thickness of the wall , in which the bracket is mounted (L = L1 + L2).

On the outer bent part of the holding pipe, a branch with a thread 10 for the stuffing box 9 is made with the possibility of laying the sensor cable 5 inside the holding pipe 4, which is then connected to the thermostat inside the building (not shown in Fig.). Branch 10 is attached to the pipe-holder 4, for example, by welding.

Make a plate for mounting the bracket 6, for example, steel, thickness, for example, 3 mm. The plate is made with side L3 of variable size, depending on the place of unhindered fastening of the bracket and the length of the outer part of the pipe-holder L1 (the larger L1, the larger L3 to ensure the stability of the bracket during operation).

In the center of the plate 6, a hole 7 is made for fitting onto the holding pipe 4 with a diameter corresponding to the outer diameter of the holding pipe 4.

At the corners of the plate, holes 8 are made for fastening to the wall of the building, with a diameter of, for example, 5 mm.

The declared bracket is assembled by serial connection of the platform 1, the pipe holder 4, the plate 6, for example, by welding, while the plate 6 is attached to the pipe holder along its cross section at a distance L1 from the platform 1 and at a distance L2 from the inner edge of the pipe holder 4. Then a gland (cable gland) 9 is connected through a threaded outlet 10 in the pipe-holder 4. For example, brass cable gland M16, d = 4-8 mm is used as a gland (cable gland) [https://www.dkc.ru /ru/catalog/198/R5BCM16/], etc.

If necessary, before assembly, the parts of the bracket are painted, for example, by the method of polymer powder coating, while at the request of the customer, the color scheme is selected in the color of the roof / facade.

Installation of the claimed bracket is carried out as follows (Figure 3).

1. Fix the assembled bracket to a vertical hard surface, for example, a wall of a building with a thickness of L2, for which:

- make a hole in the wall (parapet, dormer window) with a diameter equal to the diameter of the pipe-holder 4;

- insert the pipe-holder 4 with the inner part into the hole for the thickness of the wall L2 so that the plate 6 is adjacent to the wall;

- fasten the bracket to the wall through the holes 8 of the plate 6, for example, with a threaded connection, dowel-nails, anchors, etc.

2. Install the sensor 2 on the platform 1 and fix it through the holes 3, for example, with a threaded connection, for example, using roofing screws.

3. Lead the sensor cable 5 through the gland 9 into the pipe-holder 4 and lead the cable to the exit from the pipe-holder, then the gland 9 is tightened, and the outer part of the pipe-holder is sealed.

4. Connect the sensor cable 5 to the thermostat inside the building (not shown in Fig.).
