When installing the equipment, first fix the second fixing plate 16 on the plane with bolts, slide the power alarm body 1 and the connecting plate 11 to the inside of the limit bar 13, pull the annular buckle 10 to slide the auxiliary connecting column 19 and the gear connecting column 17, and the gear connecting column 17 will slide out of the first fixing plate 12 and contact the gear groove 18 inside the second sleeve 15. At this time, the first sleeve 14 and the second sleeve 15 can rotate normally, and the angle between the first fixing plate 12 and the second fixing plate 16 changes, thereby changing the direction of the power alarm body 1. When it is rotated to the appropriate position, press the auxiliary connecting column 19. Make the side of the gear connecting column 17 with the gear return to its original position. At this time, the side of the gear connecting column 17 with the gear will contact the first sleeve 14 and the second sleeve 15 at the same time. Because the gear grooves 18 on both sides limit the gear connecting column 17, the first sleeve 14 and the second sleeve 15 cannot rotate. Then connect the electric alarm body 1 to the line that needs to be detected. Through the set gear connecting column 17 and gear groove 18, the installation direction of the electric alarm body 1 can be changed according to actual conditions, so that the equipment can be installed in complex situations, reducing the difficulty of staff installing the equipment.

[0027] Further, such as Figure 2 、 Figure 3 and Figure 4As shown, a pair of first springs 2 are fixed to the bottom of the outer wall of the limit bar 13; a connecting bar 21 is fixed to the bottom of the outer wall of the first spring 2; a sliding column 22 is fixed to the top of the outer wall of the connecting bar 21; a limiting block 23 is fixed to the top of the outer wall of the sliding column 22; the sliding column 22 is in sliding contact with the limit bar 13; a pair of square sliding grooves 24 are opened on the side wall of the limit bar 13; the limiting block 23 is in sliding contact with the square sliding grooves 24; the limiting block 23 is in contact with the connecting plate 11. When the equipment is working, the connecting plate 11 will slide to a certain position, at which time the connecting plate 11 will contact the inclined side of the limit block 23, the connecting plate 11 will squeeze the limit block 23, the first spring 2 will be stretched, and the sliding column 22 will slide. When the connecting plate 11 continues to slide, when the limit block 23 contacts the notch of the side wall of the connecting plate 11, the first spring 2 will reset. At this time, the first spring 2 will push the limit block 23 to contact the connecting plate 11, and the connecting plate 11 cannot slide outward. When the equipment needs to be disassembled, the connecting strip 21 is pulled to make the limit block 23 separate from the connecting plate 11. By setting the limit block 23 and the connecting strip 21, the staff can quickly complete the installation and disassembly of the equipment, which is convenient for the staff to maintain and overhaul the equipment in the later stage and reduces the time spent by the staff to frequently tighten the bolts.

[0028] Further, such as Figure 1 、 Figure 3 and Figure 5 As shown, the side wall of the limit strip 13 is provided with an auxiliary slide groove 3; the auxiliary slide groove 3 is arranged on the side close to the ring buckle 10; the inner side wall of the auxiliary slide groove 3 is fixedly connected to the second spring 31; the outer side wall of the second spring 31 is fixedly connected to the third fixing plate 32; the third fixing plate 32 is in sliding contact with the limit strip 13; the third fixing plate 32 is in sliding contact with the first fixing plate 12; the side wall of the auxiliary connecting column 19 is provided with an annular groove 33; the third fixing plate 32 is in contact with the annular groove 33; the side wall of the third fixing plate 32 is fixedly connected to a shift rod 34; the shift rod 34 is in sliding contact with the auxiliary slide groove 3. When the equipment is working, when it is necessary to pull the ring buckle 10, first pull the lever 34 to disengage the third fixing plate 32 from the annular groove 33. At this time, the auxiliary connecting post 19 can slide. When the adjustment is completed, directly press the auxiliary connecting post 19. At this time, the second spring 31 will push the third fixing plate 32 so that the third fixing plate 32 contacts the annular groove 33 again. At this time, the auxiliary connecting post 19 cannot move outward. The auxiliary connecting post 19 can be fixed by the set third fixing plate 32 and the annular groove 33, thereby reducing the situation where the auxiliary connecting post 19 is pulled out due to incorrect operation, and reducing the situation where the angle between the first fixing plate 12 and the second fixing plate 16 changes due to the movement of the auxiliary connecting post 19.

[0029] Further, such as Figure 5As shown, the sidewall of the third fixing plate 32 is rotatably connected to a first ball bearing 4; a collar 41 is fixedly attached to the outer sidewall of the third fixing plate 32; and the first ball bearing 4 contacts the annular groove 33. During operation, the third fixing plate 32 continuously slides against the sidewall of the auxiliary connecting post 19, with the first ball bearing 4 preferentially contacting the auxiliary connecting post 19 and the annular groove 33. The arrangement of the first ball bearing 4 and the collar 41 reduces wear on the third fixing plate 32 over extended periods of use, thereby increasing the stability of the device.

[0030] Further, such as Figure 1 As shown, a pull rope 5 is fixed to the bottom of the outer wall of the connecting bar 21. When the power alarm body 1 needs to be disassembled, the staff needs to pull the connecting bar 21. By pulling the pull rope 5, the connecting bar 21 can be moved. The set pull rope 5 allows the staff to pull the connecting bar 21 more conveniently, making it easier for the staff to use the device.

[0031] Further, such as Figure 3 As shown, the third fixing plate 32 is made of a rigid material. When the device is in operation, the third fixing plate 32 serves to secure the auxiliary connecting column 19 as a whole. By setting the third fixing plate 32 of a rigid material, the third fixing plate 32 is less likely to break during long-term use, thereby reducing the possibility of device failure caused by breakage and increasing the stability of the device.

[0032] Further, such as Figure 6 As shown, the inner wall of the limit bar 13 is provided with a plurality of second balls 7; the second balls 7 rotate within the limit bar 13; the second balls 7 cannot escape from the limit bar 13; and the second balls 7 are in contact with the connecting plate 11. During equipment installation, workers need to push the connecting plate 11 to a certain position. At this point, the second balls 7 convert the sliding friction between the connecting plate 11 and the limit bar 13 into rolling friction, reducing the friction between the two. The provision of the second balls 7 can reduce the resistance encountered by workers when pushing the connecting plate 11.

[0033] Working principle: When installing the equipment, first fix the second fixing plate 16 on the plane with bolts, slide the electric alarm body 1 and the connecting plate 11 to the inside of the limit bar 13, pull the ring buckle 10 to slide the auxiliary connecting column 19 and the gear connecting column 17, and the side of the gear connecting column 17 with the gear will slide out of the first fixing plate 12 and contact the gear groove 18 inside the second sleeve 15. At this time, the first sleeve 14 and the second sleeve 15 can rotate normally, and the angle between the first fixing plate 12 and the second fixing plate 16 changes, thereby changing the orientation of the electric alarm body 1. When it is rotated to the appropriate position, press the auxiliary connecting column 19 to make the side of the gear connecting column 17 with the gear return to its original position. At this time, the side of the gear connecting column 17 with the gear will contact the first sleeve 14 and the second sleeve 15 at the same time. Because the gear grooves 18 on both sides limit the gear connecting column 17, at this time the first sleeve 14 and the second sleeve 15 The two sleeves 15 cannot rotate, and then the power alarm body 1 is connected to the line that needs to be detected. The gear connecting column 17 and the gear groove 18 are set, so that the installation direction of the power alarm body 1 can be changed according to the actual situation, so that the equipment can be installed in complex situations, reducing the difficulty of staff installing the equipment. When the equipment is working, the connecting plate 11 will slide to a certain position. At this time, the connecting plate 11 will contact the inclined side of the limit block 23, and the connecting plate 11 will squeeze the limit block 23. The first spring 2 will be stretched, and the sliding column 22 will slide. When the connecting plate 11 continues to slide, when the limit block 23 contacts the notch on the side wall of the connecting plate 11, the first spring 2 will reset. At this time, the first spring 2 will push the limit block 23 to contact the connecting plate 11. At this time, the connecting plate 11 cannot slide outward. When the equipment needs to be disassembled, pull the connecting strip 21 to make the limit block 23 The connecting plate 11 can be separated. By setting the limit block 23 and the connecting strip 21, the staff can quickly complete the installation and disassembly of the equipment, which is convenient for the staff to maintain and repair the equipment in the later stage and reduces the time spent by the staff to frequently tighten the bolts. When the equipment is working, when it is necessary to pull the ring buckle 10, first pull the lever 34 to disengage the third fixing plate 32 from the annular groove 33. At this time, the auxiliary connecting column 19 can slide. When the adjustment is completed, directly press the auxiliary connecting column 19. At this time, the second spring 31 will push the third fixing plate 32 to re-engage the third fixing plate 32 with the annular groove 33, at this time the auxiliary connecting column 19 cannot move outward, and the auxiliary connecting column 19 can be fixed by the third fixing plate 32 and the annular groove 33, thereby reducing the situation where the auxiliary connecting column 19 is pulled out due to incorrect operation, and reducing the situation where the angle between the first fixing plate 12 and the second fixing plate 16 changes due to the movement of the auxiliary connecting column 19. When the equipment is working, the third fixing plate 32 will continuously slide in contact with the side wall of the auxiliary connecting column 19. At this time, the first ball 4 will preferentially contact the auxiliary connecting column 19 and the annular groove 33. Through the provision of the first ball 4 and the collar 41,It can reduce the overall wear of the third fixing plate 32 during long-term use and increase the stability of the equipment. When the electric alarm body 1 needs to be disassembled, the staff needs to pull the connecting bar 21. The connecting bar 21 can be moved by pulling the pull rope 5. The set pull rope 5 allows the staff to pull the connecting bar 21 more conveniently, which is convenient for the staff to use the equipment. When the equipment is working, the third fixing plate 32 has the effect of fixing the auxiliary connecting column 19 as a whole. By setting the third fixing plate 32 to be a rigid material, the possibility of the third fixing plate 32 breaking during long-term use is reduced, and the possibility of equipment failure caused by breakage is reduced, which increases the stability of the equipment. When installing the equipment, the staff needs to push the connecting plate 11 to a certain position. At this time, the second ball 7 can convert the sliding friction between the connecting plate 11 and the limit bar 13 into rolling friction, reducing the friction between the two. The second ball 7 can reduce the resistance encountered by the staff when pushing the connecting plate 11.
