[0002] Fire hydrant, formally called fire hydrant, is a fixed fire-fighting facility, which mainly plays a role in controlling combustible materials, isolating combustion-supporting materials and eliminating ignition sources. It is divided into indoor fire hydrant and outdoor fire hydrant.

[0003] Such as the announcement for CN110237474B, the name is "a fire hydrant" of Chinese patent, including: hydrant body, valve, threaded shaft, piston and water outlet, water outlet connects water hose interface; The upper surface of the piston is fixedly connected with the top end of the water outlet, and the folding plate is made of soft material, and the folding plate is designed to prevent water from flowing back into the hydrant body, ensuring that water flows into the water hose interface from the water outlet; The thread of the threaded shaft is provided with uniformly distributed notches; A first sliding groove is formed in the threaded shaft; The gear is arranged in the first sliding groove, and the gear is fixed on the side wall of the first sliding groove through the shaft; The gear and the threaded shaft are engaged with each other; The side of the gear away from the threaded shaft is provided with a gear shaft, and the gear and the gear shaft are engaged with each other; The gear shaft is fixed on the inner wall of the first sliding groove through the shaft; The second sliding groove is formed on both sides of the water outlet, and the second sliding groove is communicated with the first sliding groove; The water outlet in the second sliding groove is sleeved with a fixed ring; The top end of the fixed ring is designed as a double-layer ring, which is sequentially divided into an upper ring and a lower ring; The gear shaft passes through the upper ring and the lower ring; The inner wall of the fixed ring is provided with a groove, and the inner wall of the groove is fixedly connected with uniformly arranged teeth; The gear shaft and the rack are engaged with each other. The above-mentioned patent solves the problem that it is time-consuming and laborious to rotate the water hose interface of the fire hose into the fire hydrant, which is not conducive to the first time to carry out fire extinguishing work.

[0004] The deficiency of the above-mentioned patent is that: however, the above-mentioned patent solves the problem that the existing fire hydrant is time-consuming and laborious when connecting the fire hose, but because the fire hose is connected with the fire hydrant all the time, the fire hose is inevitably loosened between the connection parts of the fire hydrant, causing the fire water to penetrate from the connection part, or causing the fire hose to fall off from the fire hydrant, thereby affecting the fire fighting work; And some fire hydrants use valves that need to be controlled with external tools, so after connecting the fire hydrant and the fire hose, the user needs to use external tools to use the fire water, which not only increases the workload of the staff, but also reduces the practicability of the fire hydrant to a certain extent, thereby further delaying the fire fighting work.

[0047] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] Please see Figures 1-27 This invention provides a smart fire hydrant, comprising a mounting base 1 and a hydrant body 3 fixedly mounted on the mounting base 1, and further comprising: a connecting pipe 6; a water outlet pipe 4 connected to the circumferential surface of the hydrant body 3; a connecting mechanism 7 for connecting the water outlet pipe 4 and the connecting pipe 6; a valve 5 disposed on the top of the hydrant body 3 for controlling the opening and closing of the water outlet pipe 4, the valve 5 having a handle 53 for driving the valve 5 to open and close; and a linkage mechanism 8 disposed on the hydrant body 3, which is driven by the connecting mechanism 7 when connecting the water outlet pipe 4 and the connecting pipe 6, so as to rotate the handle 53.

[0049] In the above technical solution, the connecting mechanism 7 enables the interconnection between the outlet pipe fitting 4 and the connecting pipe fitting 6, thereby minimizing the problems associated with existing fire hydrants where the hose connection is not tight enough, leading to time-consuming hose connection processes and the hose easily detaching from the hydrant, causing leaks and affecting fire fighting efforts. Furthermore, the linkage mechanism 8 allows the handle 53 to rotate under its influence when connecting the outlet pipe fitting 4 and the connecting pipe fitting 6 using the connecting mechanism 7. This facilitates easy control of the opening and closing of the outlet pipe fitting 4 via the valve 5, enabling the opening and closing of the outlet pipe fitting 4 without the need for external tools after connecting the hose to the fire hydrant. Therefore, the practicality of the fire hydrant is improved to a certain extent.

[0050] Specifically, the valve 5 includes a handle 51 rotatably mounted on the plug body 3, a mating block 52 fixedly connected to the top of the handle 51, and a mating groove 54 adapted to the mating block 52 at the bottom of the handle 53.

[0051] In the above technical solution, by utilizing the handle 51 on the hydrant body 3 and the rotating handle 53 on the handle 51, the handle 51 can rotate under the drive of the rotating handle 53. While the handle 51 is rotating, it can control the opening and closing of the water outlet pipe 4 through the valve 5. Furthermore, by utilizing the connecting block 52 at the top of the handle 51 and the connecting groove 54 on the rotating handle 53, the rotating handle 53 on the valve 5 can be disassembled when the valve 5 is not in use. Therefore, it can be minimized that the rotating handle 53 will rotate due to external influences when the fire hydrant is not in use, thereby affecting the opening and closing of the water outlet pipe 4 and wasting water resources.

[0052] Specifically, the connecting mechanism 7 includes two fixed brackets 701 respectively fixedly connected to the outlet pipe fitting 4 and the connecting pipe fitting 6. Movable rods 702 are slidably inserted into each fixed bracket 701. A first elastic element 704 is provided between each movable rod 702 and each fixed bracket 701, and a ball valve 703 is fixedly connected to the end of each movable rod 702 that is close to each other. The connecting mechanism 7 also includes a first connecting seat 706 and a second connecting seat 707 respectively connected to the outlet pipe fitting 4 and the connecting pipe fitting 6. A connecting element 708 is slidably arranged between the first connecting seat 706 and the second connecting seat 707. The two ball valves 703 respectively abut against the connecting element. At both ends of component 708; a first fixing ring 709 is fixedly installed on the circumferential surface of the first connecting seat 706, and multiple locking blocks 710 are fixedly connected to the side of the first fixing ring 709 near the connecting pipe 6; a second fixing ring 711 is fixedly installed on the circumferential surface of the second connecting seat 707, and multiple locking grooves 712 that engage with each locking block 710 are opened on the side of the second fixing ring 711 near the water outlet pipe 4; a threaded sleeve 713 is rotatably sleeved on the circumferential surface of the first fixing ring 709, and an internal threaded groove is opened inside the threaded sleeve 713; an external threaded groove that matches the internal threaded groove is opened on the circumferential surface of the second fixing ring 711.

[0053] In the above technical solution, when it is necessary to connect the inlet pipe 2 and the outlet pipe 4, the second connecting seat 707 on the connecting pipe 6 is used to move the second connecting seat 707 towards the first connecting seat 706 on the outlet pipe 4. This allows the multiple locking blocks 710 on the first fixing ring 709 to be inserted into the corresponding slots 712 on the second fixing ring 711, thus achieving the effect of connecting the outlet pipe 4 and the inlet pipe 2. After the inlet pipe 2 and the connecting pipe 6 are connected, the threads on the first fixing ring 709 are slidable. The sleeve 713 allows the threaded sleeve 713 to slide closer to the second fixing ring 711. During the sliding process, the threaded sleeve 713 rotates. Therefore, the interaction between the built-in threaded groove inside the threaded sleeve 713 and the external threaded groove on the second fixing ring 711 further improves the connection effect between the water outlet pipe fitting 4 and the connecting pipe fitting 6. This minimizes the possibility of poor connection between the water outlet pipe fitting and the connecting pipe fitting 6, which could cause fire-fighting water to leak from the connection and affect fire fighting efforts.

[0054] When the second connecting seat 707 on the connecting pipe fitting 6 moves toward the first connecting seat 706 of the water outlet pipe fitting 4, it allows the two ball valves 703 in the water blowing pipe fitting and the connecting pipe fitting 6 to abut against the connecting member 708, thereby allowing the connecting member 708 to slide relative to the first connecting seat 706 and the second connecting seat 707. After the water outlet pipe fitting 4 is connected to the connecting pipe fitting 6, the water blowing pipe fitting and the connecting pipe fitting 6 can communicate with each other, so that the fire-fighting water in the water outlet pipe fitting 4 can flow to the connecting pipe fitting 6 through the connecting member 708, thereby extinguishing the fire.

[0055] In this embodiment, refer to Figure 5 The first elastic element 704 is a spring. One end of the spring is fixedly connected to the mounting bracket, and the other end is fixedly connected to the other end of the movable rod 702 through the limiting block 705. The spring is sleeved on the circumference of the movable rod 702.

[0056] In the above technical solution, by using a spring, the ball valves 703 in the water outlet pipe fitting 4 and the connecting pipe fitting 6 can slide under the action of the spring, so that the two ball valves 703 can block the water outlet pipe fitting 4 and the connecting pipe fitting 6 respectively, thereby minimizing the possibility of fire water seeping out from the connection between the water outlet pipe fitting 4 and the connecting pipe fitting 6.

[0057] Specifically, the connector 708 includes a connecting pipe 7081, with two ball valves 703 respectively abutting against both ends of the connecting pipe 7081. The connecting pipe 7081 is divided into two sections by a partition plate 7082. One section of the connecting pipe 7081 is slidably mounted on the first connecting seat 706, and the other section of the connecting pipe 7081 is slidably mounted on the second connecting seat 707. Both sections of the connecting pipe 7081 have multiple water outlet holes 7083 on their circumferential surfaces.

[0058] In the above technical solution, when the second connecting seat 707 on the connecting pipe fitting 6 is used, and the second connecting seat 707 moves towards the second connecting seat 707 on the outlet pipe fitting 4, the connecting pipe 7081 can slide under the push of the second connecting seat 707. Therefore, since one end of the connecting pipe 7081 abuts against the ball valve 703 in the outlet pipe, the ball valve 703 can move towards the plug body 3 under the pressure of the connecting pipe 7081. When the connecting pipe 7081 slides to the partition plate 7082 and abuts against the first connecting seat 706, the other end of the connecting pipe 7081 will abut against the ball valve 703 in the connecting pipe fitting 6, so that the ball valve 703 can move away from the plug body 3, thereby enabling the outlet pipe fitting 4 to communicate with the connecting pipe fitting 6, and enabling fire-fighting water to flow through the outlet hole 7083 opened on the connecting pipe 7081.

[0059] Furthermore, referring to Figure 8 Two sealing rings 7084 are fitted on the circumferential surface of the connecting pipe 7081. The two sealing rings 7084 are located on both sides of the partition plate 7082. The first connecting seat 706 and the second connecting seat 707 are provided with relief grooves on the side that are close to each other. The two sealing rings 7084 are located in the two relief grooves respectively.

[0060] In the above technical solution, by using the sealing rings 7084 set on both sides of the partition plate 7082, the sealing effect between the water outlet pipe 4 and the connecting pipe 6 is increased.

[0061] Specifically, the linkage mechanism 8 includes a screw 808 rotatably mounted on the bolt body 3, and a transmission assembly for driving the screw 808 to rotate is provided between the threaded sleeve 713 and the screw 808; a threaded plate 810 is threadedly connected to the circumference of the screw 808, a movable plate 811 is slidably mounted on the top of the threaded plate 810, the movable plate 811 is rotatably mounted on the circumference of the screw 808, a first pulley 812 is fixedly connected to the top of the screw 808, a rotating rod 813 is rotatably mounted on the movable plate 811, a second pulley 814 is fixedly connected to the top of the rotating rod 813, and the first pulley 812 and the second pulley 814 are connected by a transmission belt 815; a rotating cylinder 816 is slidably mounted on the circumference of the rotating rod 813, the rotating cylinder 816 is rotatably mounted on the threaded plate 810, a rotating plate 817 is fixedly connected to the bottom of the rotating cylinder 816, a locking rod 818 is fixedly connected to the bottom of the rotating plate 817, and the locking rod 818 is movably mounted on the rotating handle 53.

[0062] In the above technical solution, by means of the rotation of the screw 808, the threaded plate 810 can move along the axial direction of the screw 808 towards the handle 53. While the threaded plate 810 moves towards the handle 53, the rotating plate 817, which is rotatably set at the bottom of the threaded plate 810, can rotate under the transmission of the screw 808 through the transmission between the first pulley 812, the second pulley 814 and the transmission belt 815. This causes the locking rod 818 at the bottom of the rotating plate 817 to rotate under the drive of the rotating plate 817. When the locking rod 818 on the rotating plate 817 moves to the point where its circumference contacts the handle 53, the rotation of the rotating plate 817 will drive the handle 53 to rotate, thereby controlling the opening and closing of the water outlet pipe 4.

[0063] Furthermore, referring to Figure 15 The top end of the threaded plate 810 is fixedly connected to a telescopic rod 820, and the output end of the telescopic rod 820 is fixedly connected to the sliding plate.

[0064] In the above technical solution, by utilizing the telescopic rod 820 on the threaded plate 810, the sliding direction of the sliding plate on the threaded plate 810 can be restricted.

[0065] Specifically, the transmission assembly includes a mounting ring 801 fixedly mounted on the bolt body 3, a mounting plate 802 fixedly connected to the circumference of the mounting ring 801, a screw 808 rotatably mounted on the mounting plate 802, and a guide rail 803 fixedly connected to the bottom end of the mounting plate 802; a rotating ring 714 rotatably mounted on the circumference of the threaded sleeve 713, a connecting rod 806 fixedly connected to the circumference of the rotating ring 714, multiple connecting plates 805 fixedly connected to the circumference of the connecting rod 806, a rack 804 fixedly connected to the multiple connecting plates 805, and the rack 804 slidably mounted on the guide rail 803; a first gear 807 meshing with the rack 804 is rotatably connected to the bottom end of the mounting plate 802, and a second gear 809 meshing with the first gear 807 is fixedly connected to the bottom end of the screw 808.

[0066] In the above technical solution, by utilizing a transmission component, during the process of connecting the water outlet pipe 4 and the connecting pipe 6 using the threaded sleeve 713 on the first fixed ring 709, the sliding of the threaded sleeve 713 allows the rack 804 to slide along the direction of the guide rail 803 under the drive of the connecting rod 806. At this time, the sliding of the rack 804 will drive the first gear 807 on the bottom end of the mounting plate 802 to rotate. {It is worth mentioning that there should be a certain gear ratio between the first gear 807 and the second gear 809 used here, so that while the first gear 807 rotates under the action of the rack 804, the second gear 809 on the bottom end of the screw 808 can rotate several times under the drive of the first gear 807.} Furthermore, by utilizing the linkage between the first gear 807 and the second gear 809, the screw 808 on the mounting plate 802 can rotate simultaneously with the rotation of the second gear 809.

[0067] Furthermore, referring to Figure 15 A guide rod 819 is slidably inserted on the threaded plate 810, and the two ends of the guide rod 819 are fixedly connected between the mounting plate 802 and the sliding plate, respectively.

[0068] In the above technical solution, the guide rod 819 is used to limit the sliding direction of the threaded plate 810.

[0069] Specifically, the linkage mechanism 8 also includes a locking mechanism 9, which includes a fixed plate 91 fixedly connected to the top of the bolt body 3, a sliding plate 92 slidably disposed on the fixed plate 91, and the bottom end of the locking rod 818 abutting against the top end of the sliding plate 92; a plurality of second elastic elements 93 are disposed between the sliding plate 92 and the fixed plate 91, a plurality of pins 94 are fixedly connected to the top end of the sliding plate 92, and a plurality of slots 95 adapted to each pin 94 are opened at the bottom end of the rotating handle 53.

[0070] In the above technical solution, by using the locking mechanism 9, the lever 818 moves towards the handle 53 under the action of the linkage mechanism 8, which causes the sliding plate 92 to slide downward under the action of the lever 818. This allows the multiple pins 94 on the sliding plate 92 to slide out from the slots 95 at the bottom of the handle 53. As a result, when the lever 818 rotates under the drive of the rotating plate 817, it can drive the handle 53 to rotate. Thus, by rotating the handle 53 on the valve 5, the opening and closing of the water outlet pipe 4 can be controlled.

[0071] Furthermore, referring to Figure 18 The bottom end of the lever 818 is fixedly equipped with a ball 821, which is movably mounted on the top surface of the sliding plate 92.

[0072] In the above technical solution, by utilizing the ball 821 at the bottom of the lever 818, the ball 821 on the lever 818 can roll on the top surface of the sliding disk 92 while the lever 818 is rotating, thereby reducing the friction between the lever 818 and the contact surface of the sliding disk 92 during rotation to a certain extent.

[0073] Specifically, a control mechanism 10 is also fixedly installed on the dam body 3. The control mechanism 10 includes: a mounting back plate 101, which is fixedly installed on the dam body 3; a protective shell 102, which is installed on the mounting back plate 101; a control unit 104, which is disposed between the mounting back plate 101 and the protective shell 102; a tilt detector 106, which is fixedly installed on the mounting back plate 101; a water flow sensor 107, which is fixedly installed on the mounting back plate 101; and a GPS locator 108, which is fixedly installed on the mounting back plate 101.

[0074] In the above technical solution, the tilt detector 106 on the mounting backplate 101 enables real-time monitoring of the tilt state of the hydrant body 3. When the hydrant body 3 tilts due to an unavoidable impact, an alarm is automatically sent to the user, thus minimizing unnecessary losses and water waste. The water flow sensor 107 on the mounting backplate 101 enables real-time monitoring of water usage and leakage in the fire hydrant, allowing the user to centrally supervise the fire hydrant. The GPS locator 108 on the mounting backplate 101 locates fire hydrants in abnormal states, enabling the user to quickly find abnormal hydrants. Therefore, by utilizing the tilt detector 106, water flow sensor 107, and GPS locator 108, the intelligence of the fire hydrant is improved, thereby solving the problems of difficult management, supervision, and high maintenance costs associated with traditional fire hydrants.

[0075] Furthermore, referring to Figure 24 A display screen 103 is fixedly installed on the protective shell 102.

[0076] In the above technical solution, by using the display screen 103, the operating status of the fire hydrant can be displayed intuitively on the display screen 103, thereby further improving the intelligence of the fire hydrant.

[0077] Specifically, the control unit 104 includes a mounting housing 1041 fixedly mounted on the mounting backplate 101, and the mounting housing 1041 houses a battery 1042 and a control motherboard 1043.

[0078] In the above technical solution, by utilizing the battery 1042 and the control motherboard 1043 in the mounting housing 1041, the abnormal status of the fire hydrant can be collected and fed back to the user unit through the control motherboard 1043, thereby further improving the management and supervision of the fire hydrant.

[0079] Furthermore, referring to Figure 25 A cover 105 is installed on the mounting shell 1041.

[0080] In the above technical solution, by utilizing the cover 105 on the mounting housing 1041, the battery 1042 and the control motherboard 1043 in the mounting housing 1041 are protected, thereby minimizing the impact of the external environment on the battery 1042 and the control motherboard 1043, which could affect the various monitoring operations of the fire hydrant.

[0081] Furthermore, referring to Figure 26The mounting housing 1041 has multiple clamps 1044 installed inside, and the battery 1042 is located between the multiple clamps 1044.

[0082] In the above technical solution, by utilizing multiple clamps 1044 inside the mounting housing 1041, the battery 1042 can be fixedly installed. This can minimize the risk of the battery 1042 being bumped or knocked by the shaking of the battery 1042 due to the poor limiting effect of the mounting housing 1041 on the battery 1042 when the fire hydrant tilts due to unavoidable impact.

[0083] Specifically, a water inlet pipe 2 is fixedly installed at the bottom of the mounting base 1. The water inlet pipe 2 is connected to the plug body 3. A detection pipe 21 is connected to the circumference of the water inlet pipe 2. A pipe cap 22 is threadedly connected to the end face of the detection pipe 21. A water pressure sensor 23 is fixedly installed on the pipe cap 22. The water pressure sensor 23 is located inside the detection pipe 21.

[0084] In the above technical solution, by using the water pressure sensor 23 installed in the detection pipe 21, the pressure inside the fire hydrant can be monitored, so that the user can conveniently know in a timely manner whether there is high pressure, low pressure or no pressure inside the fire hydrant.

[0085] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
