Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a smart cap for locking fire hydrants. Background Technology

[0002] Smart fire hydrant locking caps play a crucial role in the daily management and emergency use of fire hydrants. They enable intelligent locking, status protection, and emergency unlocking of fire hydrants, allowing for precise control of the hydrant valve stem. This prevents unauthorized personnel from stealing water and misoperating the valve, while ensuring that authorized firefighters can quickly open it. This improves fire hydrant management efficiency, reduces maintenance costs, and ensures timely access to fire-fighting water in emergency fire scenarios. Smart fire hydrant locking caps are widely used along urban roadsides, in residential communities and commercial complexes, and in various public areas where fire hydrants need to be installed, adapting to the intelligent transformation needs of fire hydrants in different environments.

[0003] When implementing intelligent locking, status protection, and emergency unlocking of fire hydrants to achieve precise control of the hydrant valve stem, intelligent fire hydrant locking caps are required. Existing intelligent fire hydrant locking caps are mostly of an integral structure design, with core components rigidly connected to the outer shell. This makes it easy for each component to require high-precision matching during assembly, and requires complete disassembly and replacement during maintenance. This significantly increases production costs. Rigid connections are susceptible to vibration and temperature differences, which can cause components to loosen. Furthermore, partial failures require complete replacement, increasing maintenance costs, shortening the overall service life of the equipment, and resulting in reduced product quality and shorter service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a smart cap for locking fire hydrants, which aims to improve the problem of high production costs caused by the high assembly precision requirements due to the integral structure in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire hydrant locking intelligent cap, comprising a valve stem, a flange rotatably connected to the outer wall of the valve stem, a plurality of first fixing screws fixedly connected to the top of the flange, spring hinges fixedly connected to the outer walls of the plurality of first fixing screws, a mounting plate fixedly connected to the front side of the spring hinges, a motor fixedly connected to the front side of the mounting plate, a latch fixedly connected to the output end of the motor, a locking tongue engaged at the bottom of the latch, a second fixing screw threadedly connected to the inner wall of the locking tongue, a cap threadedly connected to the inner wall of the second fixing screw, a folding hinge rotatably connected to the inner wall of the cap, and a cap body rotatably connected to the bottom of the folding hinge.

[0006] As a further description of the above technical solution:

[0007] An installation cylinder is fixedly connected to the inner wall of the cap body, and a third fixing screw is threadedly connected to the inner wall of the installation cylinder. A first fixing block is threadedly connected to the inner wall of the third fixing screw.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the first fixing block is threaded with a fourth fixing screw, and the inner wall of the fourth fixing screw is threaded with the inner wall of the cap.

[0010] As a further description of the above technical solution:

[0011] An emergency cover plate is fixedly connected to the inner wall of the mounting cylinder, and an emergency push rod is slidably connected to the inner wall of the mounting cylinder.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the valve stem is slidably connected with multiple sealing rings, the outer wall of the sealing rings is slidably connected to the inner wall of the flange, and a retaining ring is fixedly connected to the bottom of the flange.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the retaining ring is threaded with a fifth fixing screw, and the inner wall of the fifth fixing screw is threaded with the inner wall of the flange.

[0016] As a further description of the above technical solution:

[0017] A second fixing block is fixedly connected to the top of the flange, and a module control box is fixedly connected to the top of the flange.

[0018] As a further description of the above technical solution:

[0019] A signal transmission box is fixedly connected to the top of the second fixing block, and a label panel is fixedly connected to the rear side of the signal transmission box. The outer wall of the label panel is fixedly connected to the inner wall of the cap body.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, the valve stem is the basic component. The flange rotatably connected to the outer wall is fixed to the spring hinge by multiple first fixing screws, forming a stable support structure and improving the overall impact resistance. When unlocking, the motor receives a signal and starts, driving the latch to rotate and disengage from the bolt. The cap opens flexibly by means of the folding hinge, quickly exposing the valve stem for easy emergency operation. When locking, the motor rotates in the opposite direction, and the latch and bolt reset and engage. The second fixing screw reinforces the connection between the bolt and the cap, preventing loosening. The spring hinge carries the motor through the mounting plate, and its reset mechanical characteristics ensure that the components return to their positions in case of abnormality. After the cap closes, it forms a protective barrier, extending the equipment's lifespan. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides: a smart cap for locking fire hydrants, including a valve stem 1, a flange 2 rotatably connected to the outer wall of the valve stem 1, a plurality of first fixing screws 3 fixedly connected to the top of the flange 2, spring hinges 4 fixedly connected to the outer walls of the plurality of first fixing screws 3, a mounting plate 5 fixedly connected to the front side of the spring hinges 4, a motor 6 fixedly connected to the front side of the mounting plate 5, a latch 7 fixedly connected to the output end of the motor 6, a latch tongue 8 engaged at the bottom of the latch 7, a second fixing screw 9 threadedly connected to the inner wall of the latch tongue 8, a cap 10 threadedly connected to the inner wall of the second fixing screw 9, a folding hinge 11 rotatably connected to the inner wall of the cap 10, and a cap body 12 rotatably connected to the bottom of the folding hinge 11.

[0031] Specifically, motor 6 acts as the drive core. Upon receiving the unlocking signal, it drives the latch 7 to rotate. When the latch 7 disengages from the bolt 8, the cap 10 can be opened. When locking, motor 6 rotates in the reverse direction, causing the latch 7 to re-engage with the bolt 8. The second fixing screw 9 secures the bolt 8, ensuring a stable lock and preventing accidental opening. The flange 2, through its rotatable connection with the valve stem 1, provides basic support for the overall structure. Multiple first fixing screws 3 firmly fix the spring hinge 4 to the top of the flange 2. The spring hinge 4 connects... The mounting plate 5 stably supports the motor 6, preventing the motor 6 from becoming loose. The cap 10 and the cap body 12 are rotatably connected by the folding hinge 11. When closed, it can protect the internal components of the motor 6 and the latch 7, reducing the impact of the external environment. The design of the folding hinge 11 makes the cap 10 more flexible in opening and closing, making it easier for operators to operate the valve stem 1. The spring hinge 4 has a reset characteristic, which can assist the motor 6 and the latch 7 in resetting in abnormal locking scenarios, ensuring the normal operation of the locking function. The model of the motor 6 is 37GB-520.

[0032] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 An installation cylinder 13 is fixedly connected to the inner wall of the cap body 12. A third fixing screw 14 is threadedly connected to the inner wall of the installation cylinder 13. A first fixing block 15 is threadedly connected to the inner wall of the third fixing screw 14. An emergency cover plate 17 is fixedly connected to the inner wall of the installation cylinder 13. An emergency push rod 18 is slidably connected to the inner wall of the installation cylinder 13. A fourth fixing screw 16 is threadedly connected to the inner wall of the first fixing block 15. The inner wall of the fourth fixing screw 16 is threadedly connected to the inner wall of the cap body 12.

[0033] Specifically, the mounting cylinder 13 on the inner wall of the cap body 12 is the main mounting carrier for the core emergency system. The third fixing screw 14 fixes the first fixing block 15 inside the mounting cylinder 13 through a threaded connection. Then, the fourth fixing screw 16 connects the first fixing block 15 to the cap body 12. This double fixing strengthens the connection stability between the mounting cylinder 13 and the cap body 12, preventing components from loosening. The emergency cover 17 on the inner wall of the mounting cylinder 13 can normally protect the internal emergency push rod 18 from the intrusion of dust and rainwater, which could affect the internal components. In an emergency, after breaking the emergency cover 17, the emergency push rod 18, which is slidably connected inside the mounting cylinder 13, can be pushed to achieve forced unlocking, ensuring that the fire hydrant can still be quickly activated when the intelligent system fails, retaining mechanical triggering and improving the reliability of use.

[0034] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The outer wall of valve stem 1 is slidably connected with multiple sealing rings 19. The outer wall of the sealing rings 19 is slidably connected with the inner wall of flange 2. The bottom of flange 2 is fixedly connected with a retaining ring 20. The inner wall of retaining ring 20 is threadedly connected with a fifth fixing screw 21. The inner wall of the fifth fixing screw 21 is threadedly connected with the inner wall of flange 2.

[0035] Specifically, multiple sealing rings 19 slidably connected to the outer wall of valve stem 1 fit tightly against the inner wall of flange 2, filling the gap between them and effectively preventing rainwater and dust impurities from intruding into the internal structure, avoiding corrosion of internal components, and improving the overall waterproof and dustproof performance of the equipment. The retaining ring 20 fixed at the bottom of flange 2 is threadedly connected to the inner wall of flange 2 through the fifth fixing screw 21, which can limit the bottom components of flange 2, while reinforcing the installation stability of retaining ring 20 itself, preventing its displacement, further ensuring the firmness of the connection between flange 2 and other components, and improving the structural reliability of the equipment.

[0036] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 A second fixing block 22 is fixedly connected to the top of the flange 2, a module control box 23 is fixedly connected to the top of the flange 2, a signal transmission box 24 is fixedly connected to the top of the second fixing block 22, a label panel 25 is fixedly connected to the rear side of the signal transmission box 24, and the outer wall of the label panel 25 is fixedly connected to the inner wall of the cap 12.

[0037] Specifically, the module control box 23 on top of flange 2 is the core control unit, which can receive and process unlocking signals and send forward and reverse commands to motor 6 to ensure the operation of the lock control logic in normal and emergency scenarios. The second fixing block 22 is fixed on top of flange 2 to provide stable support for signal transmission box 24 and prevent its displacement from affecting signal transmission. Signal transmission box 24 is responsible for receiving external signals from card swiping and Bluetooth and transmitting them to module control box 23. Label panel 25 is fixed between the rear side of signal transmission box 24 and the inner wall of cap 12, which not only marks equipment information for easy operation and maintenance, but also isolates the internal structure and does not obstruct wireless signals, ensuring the stability of the intelligent control link.

[0038] Working principle: The valve stem 1 serves as the basic component. Its outer wall is rotatably connected to the flange 2, which is fixed to the spring hinge 4 by multiple first fixing screws 3, providing stable support for the overall structure. When unlocking, the motor 6 receives a signal and starts, driving the output end latch 7 to rotate, causing the latch 7 to disengage from the latch tongue 8. At this time, the cap 10 can be flexibly opened through the folding hinge 11, exposing the valve stem 1 for operation. When locking, the motor 6 rotates in the opposite direction, and the latch 7 and latch tongue 8 re-engage. The second fixing screw 9 fixes the latch tongue 8 to the cap 10, ensuring a stable lock. The mounting plate 5 connected to the spring hinge 4 carries the motor 6, and its reset characteristic can assist the component in resetting under abnormal conditions. The cap 12 forms a protective barrier after being closed by the folding hinge 11, ensuring the stable operation of the internal components.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
