Description

Technical Field

[0001] The utility model relates to the field of infrared alarms, in particular to an infrared alarm device. Background Art

[0002] Infrared alarms are divided into active and passive types. Active infrared alarms actively emit infrared rays. When the infrared rays hit an obstacle, they will bounce back and be received by the alarm probe. If the probe detects that the infrared rays are stationary, that is, they are continuously emitted and bounced back, then the alarm will not sound an alarm. When a moving object touches this invisible red line, the probe will detect an abnormality and sound an alarm.

[0003] After searching, the prior art disclosed in Chinese patent publication number CN220474109U is "an infrared alarm device, comprising a semicircular outer cover, an infrared alarm, and a fixing base, wherein the upper surface of the fixing base is rotatably mounted with a semicircular outer cover via a vertical rotating shaft, and the interior of the semicircular outer cover is rotatably mounted with an infrared alarm via a horizontal rotating shaft, and a sleeve is fixedly connected to one side of the outer surface of the semicircular outer cover, a cleaning cotton is provided inside the sleeve, and a plug is fixedly mounted inside the sleeve. This utility model can remove dust accumulated on the surface of the infrared alarm, thereby avoiding affecting the light emission and light reception of the infrared alarm, and at the same time, expands the detection range of the infrared alarm and improves safety." However, the following defects still exist:

[0004] (1) When in use, the height of the infrared alarm cannot be adjusted and it can only detect a single position. At the same time, the cleaning cotton cannot scrape off the hard debris attached to the infrared alarm, thereby affecting the normal use of the infrared alarm;

[0005] (2) When in use, it is not possible to completely clean the dust on the infrared alarm by only using cleaning cotton, which may easily cause dust to remain on the infrared alarm.

[0006] Therefore, we make improvements to this and propose an infrared alarm device. Utility Model Content

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] like Figure 1-5 As shown, this embodiment provides an infrared alarm device, including a frame 1, a side of the frame 1 is provided with an adjustable scraping mechanism 2, a top of the frame 1 is provided with a cleaning component 3, and a bottom of the frame 1 is provided with a rotating component 4;

[0031] The adjusting and scraping mechanism 2 includes an extension frame 201, a first servo motor 202, a first screw rod 203, a moving block 204, a scraping plate 205, a fixed plate 206, a cleaning pad 207, a second servo motor 208, a second screw rod 209, an adjusting block 210, an infrared alarm 211 and an acrylic plate 212. The extension frame 201 is fixedly connected to one side of the frame body 1, the first servo motor 202 is bolted to the inner top wall of the extension frame 201, the first screw rod 203 is fixedly connected to the output end of the first servo motor 202, the moving block 204 is threadedly connected to the outer wall of the first screw rod 203, the scraping plate 205 is fixedly connected to one side of the moving block 204, the fixed plate 206 is bolted to the inside of the moving block 204, the cleaning pad 207 is arranged on one side of the fixed plate 206, the second servo motor 208 is bolted to the inner top wall of the frame body 1, the second screw rod 209 is fixedly connected to the output end of the second servo motor 208, the adjusting block 210 is threadedly connected to the outer wall of the second screw rod 209, the infrared alarm 211 is arranged on one side of the adjusting block 210, and the acrylic plate 212 is arranged inside the frame 1. When in use, the second servo motor 208 can be started to rotate the second screw rod 209, thereby driving the adjusting block 210 and the infrared alarm 211 to rise and fall. The infrared rays emitted by the infrared alarm 211 can penetrate the acrylic plate 212 to perform normal work. When dust or hard debris adheres to the acrylic plate 212, the first servo motor 202 can be started to rotate the first screw rod 203, driving the moving block 204 to move up and down, so that the scraping plate 205 and the cleaning pad 207 repeatedly scrape and clean the acrylic plate 212 to keep the acrylic plate 212 clean. Since the fixed plate 206 is bolted to the moving block 204, the subsequent user can remove the fixed plate 206 to replace the cleaning pad 207.

[0032] like Figure 3 and Figure 5 As shown, the cleaning component 3 includes a micro water pump 301, a water tank 302, an extraction pipe 303 and a spray pipe 304. The micro water pump 301 is arranged at the top of the frame 1, the water tank 302 is fixedly connected to one side of the frame 1 and is symmetrically arranged with the extension frame 201, the extraction pipe 303 is arranged on one side of the micro water pump 301, and the other end of the extraction pipe 303 extends to the inside of the water tank 302, and the spray pipe 304 is arranged on one side of the micro water pump 301. Detergent or clean water is injected into the water tank 302, and the micro water pump 301 is started to extract the detergent or clean water in the water tank 302 from the extraction pipe 303, and spray it on the acrylic plate 212 after passing through the spray pipe 304. It is used in conjunction with the scraper plate 205 and the cleaning pad 207 to thoroughly clean the debris and dust on the acrylic plate 212.

[0033] like Figure 5As shown, the rotating assembly 4 includes a rotating ring 401, a fixed frame 402, a third servo motor 403 and a rotating column 404. The rotating ring 401 is rotatably connected to the inside of the frame 1, the fixed frame 402 is fixedly connected to the bottom of the rotating ring 401, the third servo motor 403 is bolted to the inner bottom wall of the fixed frame 402, the rotating column 404 is fixedly connected to the output end of the third servo motor 403, and the top of the rotating column 404 is fixedly connected to the bottom of the frame 1. When the angle of the infrared alarm 211 needs to be adjusted, the third servo motor 403 can be started to rotate the rotating column 404, thereby driving the frame 1 to rotate and adjusting the angle of the infrared alarm 211. The rotating ring 401 can provide protection for the rotating column 404 to prevent it from being damaged by external forces.

[0034] like Figure 3 As shown, a stabilizing rod 5 is fixedly connected to the inside of the frame 1. There are two stabilizing rods 5 and they are symmetrically arranged. The adjustment block 210 is slidably connected to the outer wall of the sliding rod.

[0035] like Figure 3 As shown, both sides of the fixed frame 402 are fixedly connected with a mounting plate 6, a threaded hole 7 is provided inside the mounting plate 6, and a threaded column 8 is connected to the inner thread of the threaded hole 7. The fixed frame 402 is placed on the ground, the threaded column 8 is screwed into the threaded hole 7, and one end of the threaded column 8 is extended to the ground to complete the fixation of the frame 1 and prevent it from shaking and affecting the normal use of the infrared alarm 211.

[0036] like Figure 3 As shown, the bottom of the second screw rod 209 is fixedly connected to a rotating block 9, and the rotating block 9 is rotatably connected to the inside of the frame 1. When the second screw rod 209 rotates, it will synchronously drive the rotating block 9 to rotate, thereby increasing the stability of the second screw rod 209 during rotation and ensuring its smooth rotation.

[0037] like Figure 3 As shown, a guide frame 10 is fixedly connected to one side of the frame 1, and a guide block 11 is fixedly connected to one side of the guide frame 10. The cleaning liquid or water flowing down the acrylic plate 212 will enter the guide frame 10, and after being guided by the guide block 11, it will flow out to both sides of the guide frame 10 to prevent liquid accumulation.

[0038] Specifically, when the infrared alarm device is in use: place the fixing frame 402 on the ground, screw the threaded column 8 into the threaded hole 7, and extend one end of the threaded column 8 to the ground to complete the fixation of the frame 1, start the second servo motor 208, and rotate the second screw rod 209, thereby driving the adjustment block 210 and the infrared alarm 211 to rise and fall. The infrared rays emitted by the infrared alarm 211 can penetrate the acrylic plate 212 and work normally. After long-term use, when dust or hard debris adheres to the acrylic plate 212, the micro water pump 301 can be started to extract the detergent or clean water in the water tank 302 from the extraction pipe 303 , after passing through the spraying pipe 304, it is sprayed on the acrylic plate 212, and then the first servo motor 202 is started to rotate the first screw 203, driving the moving block 204 to move up and down, so that the scraping plate 205 and the cleaning pad 207 repeatedly scrape and clean the acrylic plate 212 to keep the acrylic plate 212 clean. Since the fixed plate 206 is bolted to the moving block 204, the subsequent user can remove the fixed plate 206 to replace the cleaning pad 207, and the cleaning liquid or water flowing down on the acrylic plate 212 will enter the guide frame 10, and after being guided by the guide block 11, it will flow out to both sides of the guide frame 10 to prevent liquid accumulation.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
