Description

Technical Field

[0001] This utility model relates to the technical field of fence warning devices, and in particular to a warning device for pulse electronic fences. Background Technology

[0002] In modern security systems, pulsed electronic fence systems are widely used in high-security scenarios such as residential communities, industrial parks, prisons, and substations due to their proactive defense, low false alarm rate, and high-efficiency deterrence capabilities. As the core warning device of the pulsed electronic fence system, the audible and visual alarm plays a dual role of real-time deterrence and precise early warning.

[0003] When using fence warning devices, in existing technologies, audible and visual alarms are usually installed on the top of the fence support posts by bolts. This installation method requires special tools (such as screwdrivers and wrenches) to complete the installation and removal operations. The operator also needs to control the position of the alarm and tighten / loosen multiple bolts at the same time. The steps are cumbersome and time-consuming. Especially in outdoor high-altitude or complex environments (such as strong winds or narrow spaces), the difficulty of single-person operation is significantly increased. Not only is the maintenance efficiency low, but the alarm is also prone to loosening or even falling off due to tool slippage or operational errors, which seriously affects the stability of the electronic fence's warning function. In addition, the traditional bolt fixing method has the problem of stress concentration. Long-term vibration or impact can easily lead to thread wear, further reducing the reliability of installation.

[0004] Therefore, to address the issue of inconvenient maintenance efficiency when used in outdoor high-altitude scenarios, a pulse electronic fence warning device can be designed. When using this fence warning device, when installing the audible and visual alarm, first align the two protrusions at the bottom of the mounting base with the vertical entrances of the slots on both sides of the top of the fence support column, and insert the mounting base vertically downwards into the mounting slot. At this time, the protrusions slide in along the vertical section of the slot. Then rotate the audible and visual alarm to 90 degrees, so that the protrusions turn into the horizontal section of the slot. At this time, one side wall of the protrusion fits tightly with the inner wall of the horizontal section of the slot, forming an initial limit. At this time, the operator pulls the locking mechanism outwards, and the plate moves downwards due to gravity until the bottom of the plate contacts the other side wall of the protrusion, forming a secondary limit. When disassembling the audible and visual alarm, the operation is reversed. In summary, this device, through the triple linkage structure of the protrusion rotating and engaging with the slot, the plate falling downwards due to gravity and limiting the position, and the locking mechanism, achieves rapid installation and disassembly of the audible and visual alarm while ensuring installation stability. No tools are required, and a single person can complete the operation, significantly improving maintenance efficiency. Utility Model Content

[0005] To overcome the problem that when using fence warning devices, the audible and visual alarms are usually installed on the top of the fence support posts by bolts, this installation method requires special tools to complete the disassembly and assembly operations, and the operator must simultaneously control the position of the alarm and tighten / loosen multiple bolts. The steps are cumbersome and time-consuming, so it is inconvenient to improve maintenance efficiency when used in outdoor high-altitude scenarios.

[0006] The technical solution of this utility model is as follows: a warning device for a pulse electronic fence, including an audible and visual alarm for emitting a high-decibel alarm and accompanied by flashing lights to visually alert personnel. The audible and visual alarm is set on the top of the fence support column, and a mounting base is fixedly set on the bottom of the audible and visual alarm. It also includes a protrusion. The protrusion is fixedly set on the outer circumferential surface of the bottom of the mounting base. An installation groove is opened on the top of the fence support column, and slots are opened on the two adjacent sides of the top of the fence support column. The protrusion is adapted to the slots. A card is slidably embedded on the side wall of the top of the fence support column for limiting the protrusion. Two sets of slots and cards are evenly distributed along the circumference of the top of the fence support column.

[0007] Preferably, when using this fence warning device, when installing the audible and visual alarm, first align the two protrusions at the bottom of the mounting base with the vertical entrances of the slots on both sides of the top of the fence support post, and insert the mounting base vertically downwards into the mounting slot. At this time, the protrusions slide in along the vertical section of the slot. Then rotate the audible and visual alarm to 90 degrees, so that the protrusions turn into the horizontal section of the slot. At this time, one side wall of the protrusion fits tightly with the inner wall of the horizontal section of the slot, forming a preliminary limit. At this time, the operator pulls the locking mechanism outwards, and the plate moves downwards due to gravity until the bottom of the plate contacts the other side wall of the protrusion, forming a secondary limit. When disassembling the audible and visual alarm, the operation is reversed. In summary, this device, through the triple linkage structure of the protrusions rotating and engaging with the slots, the plate falling downwards due to gravity and limiting the position, and the locking mechanism, achieves rapid installation and disassembly of the audible and visual alarm while ensuring installation stability. No tools are required, and a single person can complete the operation, significantly improving maintenance efficiency.

[0008] Preferably, the outer wall of the top of the fence support post is provided with a through groove, and two sets of through grooves are evenly distributed around the top of the fence support post. The through grooves are connected to the card slots, and the card plate is slidably embedded in the through grooves. The outer wall of the card plate is fixedly provided with a protruding plate.

[0009] Preferably, guide blocks are symmetrically fixed on both sides of the card plate, and guide grooves are symmetrically opened on both sides of the inner wall of the through groove. Guide rods are fixedly installed in the guide grooves, and the guide blocks are slidably sleeved on the side wall of the guide rods.

[0010] Preferably, the outer wall of the top of the fence support post is provided with a sliding groove. Two sets of sliding grooves are evenly distributed around the top of the fence support post. The sliding groove and the through groove are connected through a channel. A locking rod that can slide laterally is provided in the through groove.

[0011] Preferably, a locking hole is provided on one side wall of the card plate, one end of the locking rod is adapted to the locking hole, and an adjustment plate is fixedly provided on the other end of the locking rod.

[0012] Preferably, a locking ring is fixedly provided on the side wall of the locking rod, and a locking spring is fixedly provided between the locking ring and the inner wall of the through groove. The locking spring is sleeved on the outside of the locking rod, with one end of the locking spring fixedly connected to the inner wall of the locking ring and the other end fixedly connected to the inner wall of the through groove.

[0013] Preferably, a sealing component is provided at the top of the fence support post, the outer circumference of the sealing component is adapted to the inner wall of the mounting groove, and the hollow inner wall of the sealing component is adapted to the outer circumference of the audible and visual alarm.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this fence warning device, when installing the audible and visual alarm, first align the two protrusions at the bottom of the mounting base with the vertical entrances of the slots on both sides of the top of the fence support post. Insert the mounting base vertically downwards into the mounting slot. At this time, the protrusions slide in along the vertical section of the slot. Then rotate the audible and visual alarm to 90 degrees, so that the protrusions turn into the horizontal section of the slot. At this time, one side wall of the protrusion fits tightly with the inner wall of the horizontal section of the slot, forming an initial limit. At this time, the operator pulls the locking mechanism outwards. The plate moves downwards due to gravity until the bottom of the plate contacts the other side wall of the protrusion, forming a secondary limit. When disassembling the audible and visual alarm, the operation is reversed. In summary, this device, through the triple linkage structure of the protrusions rotating and engaging with the slots, the plate falling downwards due to gravity and limiting the position, and the locking mechanism, achieves rapid installation and disassembly of the audible and visual alarm while ensuring installation stability. No tools are required, and a single person can complete the operation, significantly improving maintenance efficiency.

[0016] 2. The horizontal section of the protrusion and the slot provides circumferential limiting, while the contact between the plate and the side wall of the protrusion provides axial limiting. The two work together to ensure the stability of the mounting base in complex environments (such as wind vibration) and prevent loosening and falling off. The two sets of circumferentially distributed slot-plate-locking mechanisms form a balanced force, avoiding stress concentration caused by unilateral fixing, improving the impact resistance of the overall structure, simplifying the installation steps, and making the operation logic clear. The locking spring automatically pushes the locking rod to reset after the locking rod is released, avoiding safety hazards caused by human forgetting to lock. In addition, the design of the locking spring sleeved on the outside of the locking rod reduces space occupation and ensures structural compactness. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 and Figure 4 This utility model provides an embodiment: a warning device for a pulse electronic fence, including an audible and visual alarm 1, used to emit a high-decibel alarm and accompanied by flashing lights to visually alert personnel. The audible and visual alarm 1 is set at the top of the fence support column 2. A mounting base 3 is fixedly set at the bottom of the audible and visual alarm 1, and it also includes a protrusion 4. The protrusion 4 is fixedly set on the outer circumferential surface of the bottom of the mounting base 3. An installation groove 5 is opened at the top of the fence support column 2. A slot 6 is opened on the two adjacent sides of the top of the fence support column 2. The protrusion 4 is adapted to the slot 6. A card plate 7 is slidably embedded on the side wall of the top of the fence support column 2 for limiting the protrusion 4. Two sets of slots 6 and cards 7 are evenly distributed along the circumference of the top of the fence support column 2.

[0025] Please see Figure 3 and Figure 5The outer wall of the top of the fence support post 2 has a through groove 8. Two sets of through grooves 8 are evenly distributed around the top of the fence support post 2. The through grooves 8 are connected to the slots 6. The card plate 7 is slidably embedded in the through groove 8. The outer wall of the card plate 7 is fixedly provided with a protruding plate 9. Pulling the protruding plate 9 from above can drive the card plate 7 to move upward along the through groove 8. Guide blocks 10 are symmetrically fixed on both sides of the card plate 7. Guide grooves 12 are symmetrically provided on both sides of the inner wall of the through groove 8. Guide rods 11 are fixedly provided in the guide grooves 12. The guide blocks 10 are slidably sleeved on the side wall of the guide rods 11. The card plate 7 moves downward due to gravity. The guide blocks 10 on both sides slide along the guide rods 11 in the guide grooves 12 to ensure that the card plate 7 descends vertically.

[0026] Please see Figure 3 and Figure 5 The outer wall of the top of the fence support post 2 is provided with a sliding groove 13. Two sets of sliding grooves 13 are evenly distributed around the top of the fence support post 2. The sliding grooves 13 and the through grooves 8 are connected through a channel. A locking rod 14 that can slide laterally is provided in the through grooves 8. The lifting rod can slide horizontally along the sliding grooves 13. A locking hole 15 is provided on one side wall of the card plate 7. One end of the locking rod 14 is adapted to the locking hole 15. An adjusting plate 16 is fixedly provided at the other end of the locking rod 14. The locking rod 14 is inserted horizontally. Within the locking hole 15, the final locking of the card plate 7 is completed. A locking ring 17 is fixedly installed on the side wall of the locking rod 14. A locking spring 18 is fixedly installed between the locking ring 17 and the inner wall of the through groove 8. The locking spring 18 is sleeved on the outside of the locking rod 14. One end of the locking spring 18 is fixedly connected to the inner wall of the locking ring 17, and the other end is fixedly connected to the inner wall of the through groove 8. When the locking spring 18 resets, it pushes the locking ring 17, causing the locking rod 14 to extend into the through groove 8, thus completing the contact and limiting of the bottom of the card plate 7.

[0027] Please see Figure 2 and Figure 4 A sealing element 19 is provided at the top of the fence support post 2. The outer circumferential surface of the sealing element 19 is adapted to the inner wall of the mounting groove 5. The hollow inner wall of the sealing element 19 is adapted to the outer circumferential surface of the audible and visual alarm 1. After the sealing element 19 is installed, it is embedded into the remaining space of the mounting groove 5. Its outer circumferential surface is interference-fitted with the inner wall of the mounting groove 5, and its inner wall is in close contact with the outer circumferential surface of the audible and visual alarm 1. This can reduce the gap at the top of the fence support post 2 and increase stability.

[0028] When using this fence warning device, in the non-use state, the locking plate 7 is set inside the through groove 8. At this time, one end of the locking rod 14 abuts and limits the bottom of the locking plate 7.

[0029] When installing the audible and visual alarm 1, first align the two protrusions 4 at the bottom of the mounting base 3 with the vertical entrances of the slots 6 on both sides of the top of the fence support post 2, and insert the mounting base 3 vertically downward into the mounting slot 5. At this time, the protrusions 4 slide in along the vertical section of the slot 6. Then rotate the audible and visual alarm 1 to 90 degrees so that the protrusions 4 are rotated into the horizontal section of the slot 6. At this time, one side wall of the protrusions 4 is tightly fitted with the inner wall of the horizontal section of the slot 6, forming a preliminary limit.

[0030] At this time, the operator pulls the adjustment plate 16 outward, causing the locking rod 14 to slide along the slide groove 13 toward the outer wall of the fence support column 2. The end of the locking rod 14 disengages from the bottom limit of the clamping plate 7. At the same time, the locking spring 18 is compressed and stored by the locking ring 17. The clamping plate 7 moves downward due to gravity, and the guide blocks 10 on both sides slide along the guide rod 11 in the guide groove 12 to ensure that the clamping plate 7 descends vertically until the bottom of the clamping plate 7 contacts the other side wall of the protrusion 4, forming a secondary limit.

[0031] When the locking hole 15 on the side wall of the card plate 7 is aligned with the axis of the locking rod 14, the adjusting plate 16 is released, the locking spring 18 is reset and pushes the locking ring 17, which drives the locking rod 14 to be horizontally inserted into the locking hole 15, thus completing the final locking of the card plate 7. At this time, the mounting base 3 is completely fixed.

[0032] Finally, after installation, the sealing component 19 is embedded into the remaining space of the mounting groove 5. Its outer circumference is press-fitted with the inner wall of the mounting groove 5, and its inner wall is in contact with the outer circumference of the sound and light alarm 1. This can reduce the gap at the top of the fence support column 2 and increase stability.

[0033] When disassembling the audible and visual alarm 1, the operation is reversed: First, the sealing part 19 is removed, then the adjusting plate 16 is pulled to make the locking rod 14 exit the locking hole 15, the card plate 7 is pushed up into the through groove 8, then the adjusting plate 16 is released, the locking spring 18 is reset and pushes the locking ring 17, which drives the locking rod 14 to extend into the through groove 8, completing the contact limit of the bottom of the card plate 7. The audible and visual alarm 1 is rotated in the opposite direction to make the protrusion 4 turn back to the vertical section of the card groove 6, and the mounting base 3 can be taken out vertically.

[0034] In summary, this device utilizes a triple-linkage structure—the rotational engagement of the protrusion 4 and the slot 6, the gravity-induced limiting of the clamping plate 7, and the spring-reset locking—to achieve rapid installation and removal of the audible and visual alarm 1. No tools are required, and the operation can be completed by a single person, significantly improving maintenance efficiency. The horizontal section of the protrusion 4 and the slot 6 provides circumferential limiting, while the contact between the clamping plate 7 and the side wall of the protrusion 4 provides axial limiting. The combined effect of these two mechanisms ensures the stability of the mounting base 3 in complex environments (such as wind vibrations), preventing loosening and detachment. The two sets of circumferentially distributed slots 6, clamping plates 7, and locking mechanisms create balanced force distribution, preventing single-phase... The stress concentration caused by side fixing enhances the overall structure's impact resistance, while simplifying installation steps and providing a clear operating logic. The locking spring 18 automatically pushes the locking rod 14 back to its original position after release, avoiding safety hazards caused by forgetting to lock it. Furthermore, the design of the locking spring 18 being sleeved on the outside of the locking rod 14 reduces space occupation and ensures structural compactness. Through optimized mechanical structure design, this device upgrades the traditional bolt fixing method to tool-free quick assembly and disassembly while ensuring installation firmness, taking into account both practicality and reliability. It is particularly suitable for electronic fence systems that require frequent maintenance.

[0035] Through the above steps, when using this fence warning device, when installing the audible and visual alarm 1, first align the two protrusions 4 at the bottom of the mounting base 3 with the vertical entrances of the slots 6 on both sides of the top of the fence support column 2, and insert the mounting base 3 vertically downward into the mounting slot 5. At this time, the protrusions 4 slide in along the vertical section of the slot 6. Then rotate the audible and visual alarm 1 to 90 degrees, so that the protrusions 4 turn into the horizontal section of the slot 6. At this time, one side wall of the protrusion 4 is tightly attached to the inner wall of the horizontal section of the slot 6, forming a preliminary limit. At this time, the operator pulls the locking mechanism outward, and the locking plate 7 moves downward due to gravity until the bottom of the locking plate 7 contacts the other side wall of the protrusion 4, forming a secondary limit. When disassembling the audible and visual alarm 1, the operation is reversed. In summary, this device, through the triple linkage structure of the rotational engagement of the protrusions 4 and the slot 6, the gravity-induced limit of the locking plate 7, and the locking mechanism, achieves the rapid installation and disassembly of the audible and visual alarm 1 while ensuring the installation is firm. No tools are required, and a single person can complete the operation, significantly improving maintenance efficiency.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
