[0001] This utility model relates to the field of indoor fire hydrant technology, specifically to an anti-theft indoor fire hydrant. Background Technology

[0002] Fire hydrants, as essential firefighting and rescue equipment, play a vital role in people's lives. Indoor fire hydrants, due to their location indoors and proximity to the fire source, significantly improve the efficiency of firefighters and better protect people's lives and property.

[0003] Existing indoor fire hydrants are generally placed inside fire hydrant boxes. By opening the door on the box, the handwheel on the indoor fire hydrant can be operated for use.

[0004] However, existing indoor fire hydrants are located indoors, and some people steal water from them in their daily lives. This leads to insufficient water supply during firefighting, resulting in reduced water pressure and volume, which greatly reduces firefighting efficiency and compromises the safety of people's lives and property. To address these issues, a theft-proof indoor fire hydrant is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a burglarproof indoor fire hydrant, which solves the problem that some people steal water from fire hydrants in their daily lives, resulting in insufficient water supply, reduced water pressure, reduced water volume, and greatly reduced firefighting efficiency during firefighting.

[0021] By adopting the above technical solution, holding the handwheel can drive the connecting rod to rotate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an anti-theft indoor fire hydrant, which consists of a nut pair, valve stem, square block, connecting rod, spring, and insert block. Inserting the insert rod into the drive rod drives the active and driven bevel gears to rotate, causing the housing to move downwards. This moves the square block out of the limiting groove, releasing the limiting position. Simultaneously, the connecting rod moves downwards and slides on the fixed plate, compressing the spring and causing the insert block to insert into the second slot. The hydrant can only be used by rotating the handwheel. When not in use, it cannot be used normally by operating only the connecting rod, thus achieving the anti-theft effect.

[0023] 2. This utility model provides an anti-theft indoor fire hydrant, which uses a pressure sensor, a displacement sensor, an alarm, and a square block. When an operator moves the housing, the pressure sensor will not be able to detect the pressure, while the displacement sensor will detect the movement of the connecting rod. When no operator is operating the hydrant, only the connecting rod is moved. The displacement sensor detects the displacement, and the pressure sensor detects the pressure. Then, the signal receiver receives the signal and transmits it to the controller, which then controls the alarm to sound an alarm, thus providing a reminder. Attached Figure Description

[0028] Combination Figure 1 and Figure 2 This utility model discloses an anti-theft indoor fire hydrant, comprising an anti-theft shell 1. A drive rod 5 is rotatably connected through one side of the outer wall of the anti-theft shell 1. The drive rod 5 is located within the wall thickness of the anti-theft shell 1 and requires the use of a provided insert rod 4 to rotate. After use, the staff can carry the insert rod 4 away for safe storage. One end of the drive rod 5 is fixedly connected to a drive bevel gear 15. A guide rail 17 is fixedly connected to one side of the inner wall of the anti-theft shell 1, and a lead screw 18 is rotatably connected between the inner walls of the guide rail 17. When rod 18 rotates, it can drive nut pair 19 to move under the limit of guide rail 17. A limit block 13 is fixedly connected to one side of fixed plate 14, and an anti-theft shell 1 is fixedly connected to one side of limit block 13. A sliding groove 12 is opened on one side of the outer wall of shell 6. When shell 6 moves, limit block 13 slides in the sliding groove 12, which can play a certain guiding role and does not affect fixed plate 14. Limit block 13 is slidably connected to the inner wall of sliding groove 12. Insert block 21 is provided on the inner wall of second slot 26. Handwheel 10 is fixedly connected to one end of connecting rod 2.

[0029] Combination Figures 1-3The outer ring of the driving bevel gear 15 is meshed with a driven bevel gear 16. A lead screw 18 is passed through and fixedly connected to the top of the driven bevel gear 16. When the insert rod 4 is inserted into the first slot 25 in the drive rod 5, it can drive the driving bevel gear 15, the driven bevel gear 16, and the lead screw 18 to rotate, thereby driving the nut pair 19 to move. The outer ring of the lead screw 18 is threadedly connected to the nut pair 19. A housing 6 is fixedly connected to one side of the nut pair 19. A limit groove 7 is opened on one side of the inner wall of the housing 6. A square block 8 is slidably connected to the inner wall of the limit groove 7. When the housing 6 moves downward, the square block 8 moves out of the limit groove 7. Placed inside the cavity of housing 6, the valve stem 3 can rotate. The valve stem 3 is fixedly connected to one side of the square block 8. A fixing plate 14 is slidably connected between the inner walls of housing 6. A connecting rod 2 is slidably connected to one side of the fixing plate 14. A spring 20 is sleeved on the outer ring of the connecting rod 2. When housing 6 is reset, the spring 20 rebounds, driving the connecting rod 2 to reset. A plug block 21 is fixedly connected to one end of the connecting rod 2. A second slot 26 is opened at one end of the valve stem 3. An alarm component is set on one side of the inner wall of the anti-theft shell 1. A first slot 25 is opened on one side of the drive rod 5. A plug rod 4 is set on the inner wall of the first slot 25.

[0030] Combination Figure 3 and Figure 4 The alarm assembly includes an alarm 22, which is fixedly connected to the anti-theft housing 1. A signal receiver 23 is installed on one side of the inner wall of the anti-theft housing 1. When non-staff members operate the unit, only the connecting rod 2 is operated. When the connecting rod 2 moves, the displacement sensor 11 detects the movement, and the pressure sensor 9 also detects the square block 8. The signal receiver 23 receives the signal and transmits it to the controller 24. The controller 24 controls the alarm 22 to sound an alarm to alert staff. When staff members operate the unit, the 9 cannot detect the square block 8. The controller 24 is installed at the bottom of the signal receiver 23. Two pressure sensors 9 are installed on one side of the inner wall of the limit groove 7, and the square block 8 is installed on one side of the two pressure sensors 9. A displacement sensor 11 is installed on one side of the inner wall of the connecting rod 2.

[0031] Working principle: In use, the anti-theft shell 1 is placed on the valve body. When the operator uses the valve, the insert rod 4 is inserted into the first slot 25 on the drive rod 5 and rotated, driving the driving bevel gear 15 and the driven bevel gear 16 to rotate, thereby driving the lead screw 18 to rotate, causing the nut assembly 19 to move downwards, and driving the housing 6 to move downwards. At this time, the square block 8 moves out of the limiting groove 7, and the pressure sensor 9 can no longer detect pressure. Simultaneously, the housing 6 drives the connecting rod 2 to move downwards, causing the connecting rod 2 to slide on the fixed plate 14 and compress the spring 20. The insert block 21 is inserted into the second slot 26, and the handwheel 10 can then be rotated to drive the valve stem 3 to rotate for use. The displacement sensor 11 detects the movement of the connecting rod 2. When the signal receiver 23 receives a normal detection from the displacement sensor 11 and the pressure sensor 9 fails to detect, it is considered to be working normally. After use, the drive rod 5 is rotated again to reset the housing 6, the spring 20 rebounds, and the connecting rod 2 is reset. When non-staff members use the device, only the connecting rod 2 is operated. When the connecting rod 2 moves downward, the displacement sensor 11 detects the movement, the square block 8 remains in the limit groove 7, the pressure sensor 9 detects the pressure, and the signal receiver 23 receives and transmits the data to the controller 24. The controller 24 controls the alarm 22 to sound an alarm to provide a reminder.
