Description

Technical Field

[0001] The utility model relates to the technical field of alarm devices, in particular to a pulse-type electronic fence intrusion alarm device. Background Art

[0002] Electronic safety fences use advanced sensor detectors, combined with current automation technology, and have functions such as cross-border monitoring, sound and light alarm prompts, unauthorized movement alarms, and damage alarms. They can even use electric shocks to deter those who forcibly cross the border, thereby achieving the safety protection effects of blocking, warning, alarm, and deterrence.

[0003] A Chinese patent with announcement number CN214042510U discloses an outside intruder warning device for an electronic fence. The output end of a motor drives a threaded rod to rotate, and through the cooperation of a slide groove and a slide seat, the threaded sleeve is driven to move upward, so that the connecting rod drives the sound and light alarm to rise, thereby pushing open the rain shield, so that the light and sound alarm of the sound and light alarm will have the effect of warning and expelling outside intruders.

[0004] On rainy days, when the alarm rises and pushes open the rain shield, the through hole is in an open state. At this time, rainwater will pass through the through hole into the warning box. However, in the above patent document, the warning box lacks a drainage device. When rainwater remains in the warning box for a long time, the components in the warning box will be damaged and unusable, thereby affecting the service life of the alarm device.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Reference Figure 1-Figure 5 As shown, a pulse type electronic fence intrusion alarm device comprises a fixed shaft 1, a warning box 2 is fixedly installed on the upper end of the fixed shaft 1 through a supporting plate, through holes are symmetrically opened on the upper surface of the warning box 2, and rainproof plates 3 are rotatably installed at the two through holes through arc spring rods; a lifting block 4 is arranged in the warning box 2, and a driving component for driving the lifting block 4 to move back and forth vertically is arranged in the warning box 2, two support rods 5 are fixedly installed on the lifting block 4, and an alarm 6 is fixedly installed on the upper ends of the two support rods 5, and the driving component comprises a driving motor 11 fixedly installed in the warning box 2, a reciprocating screw rod 12 fixedly installed on the output shaft of the driving motor 11, and two reciprocating screw rods 12 fixedly installed on the output shaft of the driving motor 11 and two ... The limit rod 13 on the two support rods 5 and the lifting block 4 are threadedly connected to the reciprocating screw rod 12. The inner walls on both sides of the warning box 2 are provided with movable grooves, and one end of the two limit rods 13 is slidably installed in the two movable grooves respectively; when the driving motor 11 is started, it will drive the reciprocating screw rod 12 to rotate in the warning box 2. Under the action of the reciprocating screw rod 12, the lifting block 4 can be driven to move vertically upward in the warning box 2, and then the two alarms 6 are driven to move vertically upward through the support rod 5, and the rainproof plate 3 is pushed open to play an alarm role. The working principle of the driving motor 11 is the same as the working principle of the motor in the comparative document CN214042510U, and will not be introduced in detail here.

[0018] Water outlet holes 7 are provided on both sides of the warning box 2, and a plurality of water inlet holes 8 are provided at the bottom of the warning box 2. The plurality of water inlet holes 8 are connected to the water outlet holes 7 through connecting holes. A rectangular tube 9 is fixedly installed on both sides of the warning box 2. A connecting pipe 10 is fixedly connected to the rectangular tube 9. One end of the connecting pipe 10 is connected to one end of the water outlet hole 7. A water absorption component is provided in the rectangular tube 9. The water absorption component includes a sealing plate 14 sealed and slidably installed in the rectangular tube 9, two pull rods 15 symmetrically fixedly installed on the sealing plate 14, and a transmission component that drives the pull rod 15 to move vertically up and down. The side of the rectangular tube 9 A rectangular hole connected to the interior is opened on the surface, and a plurality of movable holes are opened on the upper end of the warning box 2. The transmission component includes two movable rods 16 respectively fixedly installed on the upper ends of the pull rod 15. The two movable rods 16 are respectively slidably installed in the two movable holes. Connecting rods 17 are fixedly installed at both ends of the movable rod 16. The connecting rod 17 is fixedly installed on the limit rod 13. The rectangular hole is located above the sealing plate 14. When the lifting block 4 moves vertically upward, the support rod 5 will drive the movable rod 16 to move vertically upward through the connecting rod 17, and then drive the pull rod 15 to move vertically upward through the movable rod 16. The pull rod 15 then drives the sealing plate 14 to move vertically upward in the rectangular tube 9. When the sealing plate 14 moves to the top of the rectangular hole, the air in the rectangular tube 9 will be squeezed into the connecting pipe 10, and then enter the water outlet hole 7 and the water inlet hole 8 through the connecting pipe 10, and enter the warning box 2. When the air enters the water outlet hole 7 and the water inlet hole 8, the impurities blocked in the water outlet hole 7 and the water inlet hole 8 can be blown out. At the same time, the air entering the warning box 2 can cool the driving motor 11. When the lifting block 4 moves vertically downward, the support rod 5 passes through the connecting rod 17 and the moving rod 17. The rod 16 and the pull rod 15 drive the sealing plate 14 to move vertically downward in the rectangular tube 9. At this time, the internal space of the rectangular tube 9 becomes larger, thereby generating suction in the connecting pipe 10. Under the action of the suction, the rainwater in the warning box 2 can enter the water outlet 7 and the water inlet 8, and then be sucked into the rectangular tube 9 through the connecting pipe 10. When the sealing plate 14 moves to the bottom of the rectangular hole, the rainwater in the rectangular tube 9 will flow out from the rectangular hole, thereby removing the rainwater in the warning box 2, avoiding long-term accumulation of rainwater in the warning box 2 and causing damage to components, thereby effectively improving the service life of the alarm device.

[0019] Sealing pads are fixedly installed on the upper and lower surfaces of the sealing plate 14. The sealing pads are in sliding contact with the inner wall of the rectangular tube 9. The sealing pads can improve the sealing between the sealing plate 14 and the rectangular tube 9, so that the sealing plate 14 can generate better suction during the movement.

[0020] In the utility model, when the lifting block 4 moves vertically downward, the support rod 5 will generate suction in the rectangular tube 9 through the water absorption component, and generate suction in the connecting pipe 10. Under the action of the suction, the rainwater in the warning box 2 will enter the water outlet 7 and the water inlet 8, and then be sucked into the rectangular tube 9 through the connecting pipe 10. When the sealing plate 14 moves to the bottom of the rectangular hole, the rainwater in the rectangular tube 9 will flow out from the rectangular hole, thereby removing the rainwater in the warning box 2, avoiding the long-term accumulation of rainwater in the warning box 2 and causing damage to the components, thereby effectively improving the service life of the alarm device.
