Description

The invention relates to devices for collecting and draining rain and melt water from ground and road surfaces and can be used in the improvement of yards, squares, gardens, parks, for example, for the formation of pedestrian zones, sidewalks, bicycle paths, etc.

Linear drainage is a system of buried gutters (drainage channels, trays), which are usually closed from above with protective and decorative drainage gratings.

Fastening the grating to the drainage channel tray is one of the most important components of the rainwater and meltwater collection and drainage system.

The simplest and most common way of attaching the grating to the drainage channel tray is bolting. For this purpose, holes are made in the lattice along the longitudinal edge for bolts, and threaded holes are made in the drain channel in the planes on which the lattice is installed. These holes are for attaching bolts to fix the grill to the tray.

The disadvantage of this solution is the rapid corrosion that occurs in the pair of the fastening bolt and the thread in the hole. An example of the fight against corrosion can be the solution given in the patent of the Russian Federation for utility model No. 148515 "Storm tray and element of the storm channel" (publ. 10.12.2014, prior. 02.07.2014). The patent proposes to use a nut to fasten the bolt, installed in a specially created hole in the embedded element. The proposed solution allows replacing a worn-out fastening pair, but does not solve the problem of corrosion.

Another solution proposed in the design given in the patent of the Russian Federation for invention No. 2667774 "Protective grill" (publ. 24.09.2018, prior construction. The proposed solution avoids the use of threaded fasteners. The disadvantage of the proposed solution is that the use of the proposed solution is possible only for gratings made of light sheet material. The gratings are fastened by means of stops in the side walls of the structures, on the surface of which the grating is attached. The stop is carried out by bending the metal tape from which the clamp is made. The proposed solution is not reliable enough when used on roads with car traffic.

Closest to the claimed solution is the solution described in the RF patent for invention №2327841 (publ. 27.06.2008, prior. 04.10.2004) "Fastening device" and selected as a prototype. The patent discloses a fastening device for securing a cover to be fitted to the upper edge of a buried gutter body. The fastening device comprises first fastening elements provided on the cover and second fastening elements provided on the ground housing. In the fastening device, said first and second fastening elements are snap-connected to each other in order to secure the cover to a housing located in the ground. In this case, the first fastening elements and / or the second fastening elements each have at least one shock-absorbing section with a support surface forming a contact surface between the housing located in the ground and the cover. As a result, the cover is held in the fixed position at a distance from the upper edge of the housing located in the ground.

Fasteners, for example, performed on the lid, according to the description, are proposed to be performed either in one piece with the lid, or to be fixed as rigidly as possible to the lid so that the element does not lose attachment with the lid when it is removed from the gutter body.

In the process of use, the drainage channel tray must be regularly subjected to preventive maintenance, such as cleaning, for example, from foliage or debris, for which it is necessary to remove and reinstall the grate, called in the prototype a cover. These actions can lead to the detachment of the fastener made on the cover.

The main disadvantage of the solution described in the prototype is the difficulties arising when replacing a broken grid as a result of preventive maintenance. In other words, if, for example, a fastening element located on the grill breaks off during maintenance work, the entire grill has to be replaced.

The problem solved by the invention is the creation of a stormwater inlet channel with a unit for attaching the grating to the tray, allowing simple and multiple installation and removal of the grating without damaging it.

The technical result obtained as a result of the application of the present invention is to increase the manufacturability of the structure of the storm inlet channel, which is expressed, for example, in improving the performance, in increasing the convenience when carrying out preventive work to clean the storm inlet channel, as well as maintainability.

The problem is solved, and the technical result is achieved by the fact that the element of the storm inlet channel consists of a rain inlet tray and a lattice installed on it, made of cast iron. The rainwater chute has two opposite longitudinal side walls, on each of which there are horizontal planes for installing the lattice. At the same time, grooves are made in the horizontal planes of the side walls of the rain inlet tray, and thorns are made in the lattice, mating with the grooves. Horizontal longitudinal grooves are made in the longitudinal side walls of the stormwater inlet for fixing the grating. In the longitudinal edges of the lattice, there are seats for installing clamps in them, while the clamp for the grating of the stormwater channel is provided with a groove for installation in the seat of the grill. Also, the latch is equipped with an elastic element that engages with a horizontal longitudinal channel made in the longitudinal side walls of the rain inlet chute.

Preferably, the element of the rain inlet channel is provided with metal support strips located between the horizontal planes of the side walls of the trough and the grating. In the metal support strips, there must be places for placing the spikes of the lattice, which mate with the mating grooves made in the longitudinal horizontal planes of the rain inlet chute.

Also, the problem is solved, and the technical result is achieved by the fact that the drain channel has two opposite longitudinal side walls, on each of which there are horizontal planes for installing the lattice. At the same time, horizontal longitudinal grooves are made in the longitudinal side walls of the stormwater inlet for installing the lattice retainer with an elastic element. Moreover, grooves are made in the horizontal planes for installing the grating.

The problem is also solved, and the technical result is achieved by the fact that the lattice of the surface storm inlet channel is made of cast iron and installed on the longitudinal horizontal planes of the storm inlet channel. Moreover, in the longitudinal edges of the lattice, there are seats for installing clamps in them. The lattice is equipped with thorns located on the planes mating with the longitudinal horizontal planes of the rain inlet chute.

The problem is also solved, and the technical result is achieved by the fact that the latch of the drainage channel grill, which is installed on the horizontal planes of the longitudinal side walls of the tray, is equipped with a groove for installation in a seat made in the longitudinal edge of the grill. Moreover, the latch is made with an elastic element that engages with a horizontal longitudinal channel made in the longitudinal side walls of the tray.

The presence of horizontal planes at the rainwater tray with grooves for mating with the spikes with which the grill is equipped makes it possible to simply and quickly install the grill on the tray. Execution of horizontal longitudinal grooves in the side walls of the rainwater tray allows them to be used to fix the grating installed on the tray.

Metal support strips can be installed on the tray between the horizontal planes of the side walls of the tray and the grid. In the metal support strips, there are places for placing the spikes of the lattice, which are mated with the mating grooves made in the longitudinal horizontal planes of the rain inlet chute. This creates additional strength and reinforces the rain inlet element, increasing the additional permissible load on it.

The grating of the surface storm inlet channel is made of cast iron, which makes it suitable for installation in places with increased external load on the storm inlet channel, for example, a large flow of vehicles, parking lots, etc., that is, it makes it possible to improve the operational qualities of the storm inlet channel as a whole.

The presence of thorns in the lattice located on the planes mating with the longitudinal horizontal planes of the rain inlet tray allows you to accurately install the lattice in place of fixation. In this case, the clamps installed in the seats made in the longitudinal edges of the grating allow you to fix the grating on the rain inlet tray. Due to the design of the invention, this is a simple and easy process.

The fact that the latch of the drainage channel grill is provided with a groove for fixing the latch in the seat made in the lattice allows replacement in the event of a breakage of the latch. And the fact that the latch is made with an elastic element engaging with a horizontal longitudinal groove made in the longitudinal side walls of the chute allows you to simply and quickly, without the use of additional equipment, install and remove the grate from the storm channel chute. This solution greatly simplifies, for example, preventive maintenance work on cleaning the stormwater channel, and also increases maintainability, which is the claimed technical result, namely, an increase in the manufacturability of the stormwater channel structure.

In the following, the invention is illustrated by a detailed description of a specific, but not limiting the present solution, a variant of its implementation and the accompanying drawings, in which:

- fig. 1 - assembly drawings of the grating attachment point and the drainage channel tray are presented;

- fig. 2 - drainage channel tray;

- fig. 3 - an embodiment of the lattice with installed clamps;

- fig. 4 - the lattice lock of the drainage channel tray.

The element of the stormwater channel consists of the stormwater inlet channel 1 (Fig. 2), 2 grids 2 (Fig. 3) installed on the stormwater inlet channel 1 and a retainer 3 (Fig. 4) designed to secure the installed lattice 2 on the stormwater channel 1. An assembly drawing of the attachment point of the grating 2 on the rain inlet tray 1 is shown in Fig. 1.

In the given example, two cast-iron gratings 2 are installed on one tray 1, which is due to their relative severity. This solution also improves the manufacturability of the design. However, another solution is possible in terms of the number of installed grids 2 and the number of trays 1.

From the assembly drawing in FIG. 1, it can be seen that a groove 4 is made on the side wall of the rainwater tray 1. From FIG. 2 it can be seen that there are 8 such grooves on one tray 1, in the presented version there are 8 pieces, 4 grooves 4 on each side of the tray 1.

The groove 4 is designed to interact with the elastic element 5 of the retainer 3. This allows them to be used to fix the grate 2 installed on the rain inlet tray 1.

As seen in FIG. 1, the latch 3 is installed in the seat 6 of the lattice 2, pushing the latch 3 into the specified seat 6 along the groove 7 made on the latch 3, see also FIG. 4. The proposed fastening of the retainer 3 allows its quick replacement in case of damage.

The rainwater chute 1 has horizontal planes 8 for mounting the grating 2. As can be seen from FIG. 2, grooves 9 are made in horizontal planes 8. In turn, spikes 10 are made on the grating 2 on the surface mating with the horizontal planes 8. tray 1 precisely, ensuring that the elastic element 5 of the retainer 3 falls into the groove 4 of the side wall of the rainwater tray 1. Also, the interaction of the pins 10 and the grooves 9 allows avoiding the longitudinal displacement of the grating 2 along the horizontal planes 8 of the stormwater tray 1.

It should be borne in mind that the use of metal support strips 11, located between the horizontal planes 8 of the side walls of the tray 1 and the grating 2, creates additional strength and strengthens the rainwater channel element, increasing the additional permissible load on it. In the metal support strips 11, there are places for placing the spikes 10 of the lattice, which mate with the mating grooves 9, made in the longitudinal horizontal planes 8 of the rain inlet tray 1.

To install the stormwater canal system, it is necessary to place one or more stormwater trays 1 in a previously prepared recess on the surface of the site from which the catchment will be made. Fix it from the outside using concrete mortar.

Then assemble the grille 2 to be installed, for which the retainers 3 should be inserted along the groove 7 into the seats 6. Insert the retainer 3 until it stops.

Install the metal support strips 11 on the horizontal planes 8 of the rain inlet chute 1 so that the grooves 9 made in the horizontal planes 8 of the side walls of the storm chute 1 are open.

Install the lattice 2, equipped with spikes 10 on the metal support strips 11 so that the spikes 10 enter the grooves 9, made in the horizontal planes 8 of the side walls of the rainwater tray 1.

Due to the mating tenons 10, made on the grid 2, and the grooves 9, made on the horizontal planes of the side walls of the rainwater tray 1, the grid 2 takes a unique position on the tray 1. The latches 3, already installed in the lattice 2, are located in the places necessary for the elastic element 5 of the lock 3 to fall into the groove 4 of the side wall of the rain inlet channel 1.

To carry out technological operations for cleaning the stormwater inlet, pull the edge of the grate 2, remove the grate 2 from the tray 1, clean the tray 1.

It is very unlikely to carry out repair work on the grille 2, however, if necessary, it is possible to remove the broken retainer 3 and replace it with a new retainer 3. This operation is very simple.

The element of the storm inlet channel, made according to the invention, allows simple and repeated installation and removal of the grating 2 without damaging it, which increases the manufacturability of the structure of the storm inlet channel. The structure of the storm inlet channel element proposed in the invention makes it easy and simple to carry out preventive work to clean the storm inlet channel, as well as, if necessary, repair the grating 2.
