Description

Technical Field

[0001] The utility model relates to the technical field of infrared alarms, and more specifically to an information collection and control device for infrared alarms. Background Art

[0002] The principle of open-circuit infrared alarm is mainly based on infrared sensing technology. It usually consists of two parts: infrared transmitter and infrared receiver. The infrared transmitter emits a beam of infrared light, which will be reflected back and then received by the infrared receiver. When a person or object enters the sensing range of the infrared light, it will cause the reflection of the infrared light to change. This change will be detected by the infrared receiver, triggering the alarm to sound an alarm. The sensing range of the infrared burglar alarm is usually a cone-shaped area, which can be adjusted as needed. When installing the infrared burglar alarm, you need to pay attention to avoid blocking the emission and reception of infrared light to ensure its normal operation.

[0003] There are many existing technologies for infrared alarm information collection and control devices, such as:

[0004] Chinese patent application No. 202011533600.6 discloses an alarm body, a connecting plate, a connecting rod, a horizontal plate, a vertical plate, a first T-shaped slider and a second T-shaped slider. The vertical plate is fixed on the wall. A first T-shaped slide groove in the vertical direction is provided in the middle of the front end of the vertical plate. The first T-shaped slider is located in the first T-shaped slide groove and is tightly slidably connected with the first T-shaped slide groove. Multiple groups of through holes in the left and right directions are evenly arranged at the left and right ends of the vertical plate, wherein two groups of through holes are provided with fixing pins. The left ends of the two groups of fixing pins extend into the left ends of the two groups of through holes on the left side and pass out from the right ends of the two groups of through holes on the right side. The two groups of fixing pins are in close contact with the top and bottom ends of the first T-shaped slider, respectively.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] The principle of open-circuit infrared alarm is mainly based on infrared sensing technology. It usually consists of two parts: infrared transmitter and infrared receiver. The infrared transmitter emits a beam of infrared light, which will be reflected back and then received by the infrared receiver. When a person or object enters the sensing range of the infrared light, it will cause the reflection of the infrared light to change. This change will be detected by the infrared receiver, triggering the alarm to sound an alarm. The sensing range of the infrared burglar alarm is usually a cone-shaped area, which can be adjusted as needed. When installing the infrared burglar alarm, you need to pay attention to avoid blocking the emission and reception of infrared light to ensure its normal operation.

[0023] like Figure 1-3 As shown, the device includes a base 1. Considering that too strong sunlight affects the operation of the infrared alarm, the specific configuration is as follows: a slide groove 11 is provided on the top of the base 1, a groove 13 is provided in the middle of the top of the base 1, racks 33 are fixedly connected to the two ends of the top of the base 1, and the number of racks 33 is two. A gear 32 is meshedly connected to the outer surface of the rack 33, and a second shaft 34 is fixedly connected to the inner axis of the gear 32. A side plate 37 is rotatably connected to the outer surface of the inner end of the second shaft 34, and a baffle 38 is fixedly connected to the top of the side plate 37. The bottom of the side plate 37 is fixedly connected to Slider 35, the outer surface of the slider 35 is slidably connected to the inner surface of the slide groove 11. The existing infrared sensor is easily affected by the light intensity. When used outdoors, it is easy for sunlight to directly hit the sensor. Due to the infrared components contained in the sunlight, it will cause certain interference and influence on the signal of the infrared sensor, thereby reducing its detection accuracy and reliability, causing the signal output by the sensor to be distorted or misjudged, which is easy to cause measurement abnormalities or even interlock parking situations. The scope of use is limited. The baffle 38 is used to block the sunlight to achieve that the sensor operation is not affected by too strong light.

[0024] The improvement of this embodiment is that:

[0025] The rotation of the worm 3 drives the worm wheel 31 to rotate, drives the second rotating shaft 34 to rotate, drives the gear 32 to rotate back and forth on the rack 33, causes the slider 35 to slide back and forth inside the slide groove 11, and drives the baffle 38 to slide back and forth. When shading is needed, the sunlight shines from top to bottom, and the second rotating shaft 34 drives the gear 32 to rotate back and forth on the rack 33 by rotation, drives the side plate 37 to move back and forth, drives the baffle 38 to move back and forth, and the baffle 38 blocks the top of the infrared alarm 12; when the sunlight is weak, the second rotating shaft 34 drives the gear 32 to rotate back and forth on the rack 33 by rotation, drives the side plate 37 to move back and forth, and drives the baffle 38 to move to the top or bottom of the infrared alarm 12, so that the sunlight can shine on the infrared alarm 12.

[0026] Taking into account that the worm wheel 31 is not convenient to rotate, the worm wheel 31 is fixedly connected to the outer surface of the second rotating shaft 34 at the right end of the gear 32, and the rear outer surface of the worm wheel 31 is meshingly connected to the worm 3, and the worm 3 is rotatably connected to the inside of the baffle 38. The top of the baffle 38 is fixedly connected to the motor 36, and the end of the output shaft of the motor 36 extends into the inside of the baffle 38 and is fixedly connected to the end of the worm 3, so as to realize the convenient rotation of the worm wheel 31 and improve the degree of automation.

[0027] Taking into account that the infrared alarm 12 cannot collect data in all directions, a third rotating shaft 102 is rotatably connected to the bottom of the groove 13, and a fixed plate 22 is rotatably connected to the top of the third rotating shaft 102. The top of the fixed plate 22 is fixedly connected to the infrared alarm 12, and the outer surface of the third rotating shaft 102 is fixedly connected to a bevel gear 21. There are two bevel gears 21, and the outer surfaces are meshed with each other. The other bevel gear 21 is fixedly connected to the first rotating shaft 2 at the axis center, and a circular hole 26 is opened at the middle end of the first rotating shaft 2. The left outer surface of the first rotating shaft 2 is rotatably connected to the inside of the base 1, and the left end of the first rotating shaft 2 is fixedly connected to a handle 27, so as to realize collection in all directions and improve the scope of application.

[0028] Taking into account that the external alarm 12 is prone to deviation after the direction is determined, a bolt 23 is connected through the top thread of the base 1, a fixing block 24 is fixedly connected to the outer surface of the bolt 23, and a columnar block 25 is fixedly connected to the bottom right of the fixing block 24 to achieve directional stability of the external alarm 12.

[0029] In summary, the working principle of this solution is as follows:

[0030] The motor 36 is powered on, the motor 36 drives the worm 3 to rotate, the worm 3 drives the worm wheel 31 to rotate, the worm wheel 31 drives the second shaft 34 to rotate, and the second shaft 34 drives the gear 32 to rotate, and the slider 35 slides in the slide groove 11, so that the baffle 38 moves back and forth on the rack 33 along with the second shaft 34. When sunshade is needed, the second shaft 34 rotates to drive the gear 32 to rotate back and forth on the rack 33, drive the side plate 37 to move back and forth, drive the baffle 38 to move back and forth, and the baffle 38 moves back and forth. 38 blocks the top of the infrared alarm 12; when the sunlight is weak, the second rotating shaft 34 rotates to drive the gear 32 to rotate back and forth on the rack 33, driving the side plate 37 to move back and forth, and driving the baffle 38 to move to the top or bottom of the infrared alarm 12, so that the sunlight can shine on the infrared alarm 12. When the direction of the infrared alarm 12 needs to be adjusted, the handle 27 is manually turned to turn the infrared alarm 12 to the ideal position, the column block 25 is inserted into the circular hole 26, and the bolt 23 is manually tightened.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
