Description

Pattern description

The object of the utility model is a bird deterrent device, in two variants, applicable in horticultural crops and in fruit orchards to repel birds in order to protect crops.

From the Polish patent application P-351802, a bird-scaring device is known, resembling the head of a bird of prey, mounted on an elastic element, which performs free movements resembling a nodding of a falcon's head preparing to attack.

There is a known from the Polish patent application P-382412 a repeller, especially of birds, that uses wind energy to cause movement and sounds. The repeller automatically adjusts to the direction of the wind so as to make the most of its energy, thanks to which the deterrent effects in the form of movement and sounds are generated at low wind speeds. The shapes of the lobes and the movements of the bird of prey caused by the wind pressure, and the sounds made at the same time, increase the effectiveness of deterrence. The repeller has a hanger, rotating on a bearing, fixedly connected to the airfoil, which, in the range limited by the hanger, can tilt by several degrees to both sides from the plane in which the bearing rotation axis and the airfoil lie. The bearing is mounted on the upper end of an elastic rod, the lower end of which is fixedly connected to the protected object.

There is known from WO 03101192 a restraint device, especially for birds, which has rod-like elements made of flexible, flexible material attached to and projecting from an annular slider which is slidably coupled to a tubular fastening element connected to the base. In the base there is an electric motor which, via the output drive shaft, rotates the tubular fastening element with the arcuate rod elements.

There are also known bang devices as well as devices generating the voices of birds of prey, which are used to scare birds away.

The device for deterring birds in the first variant of the utility model is characterized in that the supporting poles are arranged in pairs in space and at intervals, the supporting poles have upper brackets on which the upper rollers are mounted, and moreover, one supporting pole of each pair has a bracket the lower one with a screw tension, articulated on the support pillar through the lower mounting eye and the upper mounting eye, while the motor and the lower drive roller are mounted on the lower bracket, and in the lower mounting eye there are additional guide rollers, and in addition, a second support pole from each the pair has a bottom bracket with a bottom roller, and in addition, a bottom limit switch is located on the bottom bracket, and an upper limit switch is located on the top bracket, and besides, between each pair of support poles there is a pipe at the bottom through which the cable is led, stretched on the upper rollers, the lower roller and the lower driving roller, and on the cable zone are bird models with fins on the tendons. In the second variant of the utility model, the supporting poles are preferably arranged in a quadrilateral arrangement of four, have lower reels and upper rollers, while a line is led through the lower reels and upper rollers, and a net with arranged bird models with ballasts is stretched over it.

The object of the utility model, in an exemplary embodiment, is shown in the drawing, in which fig. 1 shows the arrangement of the device in the first variant in the orchard, fig. 2 - construction of the device in the first variant, fig. 3 - arrangement of the device in the second variant in the orchard, fig. 4 - bird model.

The device in the first variant of the utility model consists of poles (1) placed in pairs near the trees (11) in any space, with any spacing and number of pairs. The posts (1) have brackets (6) at the top, on which the upper rollers (4) are mounted. At the bottom, one post (1) of each pair has a bracket (2.2) with a screw tension (2.4), articulated on the post (1) through the lower fixing eye (2.6) and the upper fixing eye (2.5), while on the bracket ( 2.2), the motor (2.1) is installed to drive the lower drive roller (2.3). Additionally, guide rollers (2.7) are located in the lower mounting eye (2.6). At the bottom, the second post (1) of each pair has a bracket (5) with a lower roller (3). There is the lower limit switch (7) on the bracket (5), and the upper limit switch (8) on the bracket (6). Between the pair of poles (1) at the bottom there is a tube (10) through which the cable (9) is led, stretched over the upper rollers (4), the lower roller (3) and the lower drive roller (2.3). The guide rollers (2.7) ensure the correct position of the cable (9) in the tube (10) when the position of the bracket (2.2) is adjusted by means of the screw tension (2.4). On the rope (9), the bird models (12) with ballasts (14) are suspended on the tie rods (13), which ensure that the bird model (12) is facing the wind direction. The motor (2.1) winds the cable (9) with the bird models (12) on rollers (2.3), (3) and (4) in both directions, the direction of rotation of the motor (2.1), and thus the direction of movement of the cable (9) with bird models (12), it is changed each time by actuating the lower limit switch (7) or the upper limit switch (8). In the second variant of the utility model, four poles (1) are placed near the trees (11). They are equipped with lower reels (16) and upper rollers (4), with a line (9) running through the reels (16) and rollers (4), and a net (15) with patterns of the bird (12) stretched on it.

Claims (2)

Protective reservations 1. A device for deterring birds, having an element in the form of a bird of prey model, using the wind to induce movement and self-aligning in the direction of the wind, moreover having flexible elements in the form of lines and strings, as well as an engine and rollers, characterized in that the supporting poles (1) are arranged in pairs in space and at intervals, the supporting poles (i) have upper brackets (6) on which the upper rollers (4) are mounted, and in addition, one supporting pillar (1) of each pair has a lower bracket (2.2) with shear pull (2.4). it is articulated on the support column (i) through the lower fixing eye (2.6) and the upper fixing eye (2.5), with the motor (2.1) and the lower driving roller (2.3) mounted on the lower bracket (2.2). and in the lower mounting eye (2.6) there are additional guide rollers (2.7). and in addition, the second support pole (1) of each pair has a bottom bracket (5) with a bottom roller (3), and in addition, the bottom bracket (5) has a lower limit switch (7), and the upper bracket (6) has the upper limit switch (8), and there is a tube (10) at the bottom between each pair of bearing poles (1). through which the cable (9) is routed, stretched over the upper rollers (4), the lower roller (3) and the lower drive roller (2.3). and on the cable (9), bird models (12) with ballasts (14) are suspended on the cables (13). 2.
