Description

Technical Field

[0001] This utility model belongs to the field of fire hydrant technology, and in particular relates to an intelligent outdoor fire hydrant. Background Technology

[0002] Outdoor fire hydrants are fixed water supply facilities installed on the fire water supply network outside buildings. They are mainly used for fire trucks to draw water or for direct connection of fire hoses for firefighting and are considered basic fire protection equipment. The system consists of a fire water source, a pipe network, the fire hydrant body, and accessories, and is mostly made of cast iron or copper alloy.

[0003] In the existing technology, most fire hoses are connected to the outlet pipe of outdoor fire hydrants using threads, so that water can be sprayed out through the fire hose and the nozzle. However, the threads on the surface of the outlet pipe are prone to breakage due to external forces during long-term exposure, resulting in a loose connection of the fire hose. Therefore, this technology needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent outdoor fire hydrant that solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an intelligent outdoor fire hydrant, comprising a fire hydrant body, a first straight pipe fixedly installed at the bottom of the fire hydrant body by bolts, an alarm at the front end of the first straight pipe, a water pressure sensor at the side of the first straight pipe, a second straight pipe fixedly installed at the bottom of the first straight pipe by bolts, a water flow meter inside the second straight pipe, a wireless communication device at the back end of the fire hydrant body, a water outlet pipe at the front end of the fire hydrant body, and a protective mechanism at the end of the water outlet pipe away from the fire hydrant body; the protective mechanism includes a groove at the bottom of the water outlet pipe, a slider slidably connected inside the groove, a protective shell fixedly connected at the end of the slider away from the groove, a rotating shaft at the top of the protective shell, a sealing cover fixedly connected to the surface of the rotating shaft, a compression spring at the rear end of the groove, a slot at the top of the groove, a through-hole and slidably connected post at the bottom of the slider, and deceleration mechanisms on both sides of the slider.

[0007] Furthermore, both the water pressure sensor and the water flow meter are electrically connected to the alarm via built-in wires. The alarm is also electrically connected to a wireless communication device via built-in wires. The water pressure sensor detects the water pressure, and the water flow meter detects the water flow. When there is a problem with the water pressure or water flow, a signal is transmitted to the alarm to activate the light. The alarm then transmits a signal to the wireless communication device, which then reports the issue to the fire hydrant management system.

[0008] Furthermore, the water outlet pipe has threads on both its surface and inner wall, and a sealing cap is threaded to the end of the water outlet pipe away from the fire hydrant body. The threads on the inner wall of the water outlet pipe are used for installing the sealing cap, and the threads on the surface of the water outlet pipe are used for connecting to the water hose.

[0009] Furthermore, the diameter of the insertion post is equal to the diameter of the slot, and the bottom of the insertion post protrudes beyond the bottom of the protective shell, allowing the insertion post to be inserted into the slot.

[0010] Furthermore, the frictional force between the insert and the slider is greater than the weight of the insert itself, and the weight of the insert itself will not cause it to move downwards.

[0011] Furthermore, the deceleration mechanism includes a bracket, which is fixedly connected to the side of the slider, and a roller is rotatably connected to the inner side of the bracket, with a deceleration strip fixedly connected to the surface of the roller.

[0012] Furthermore, in the initial state, the side of the roller is in contact with the inner wall of the groove. When the roller moves with the slider, it will rub against the inner wall of the groove and thus rotate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting a protective mechanism, can protect the water outlet pipe and the threads on the surface of the water outlet pipe through the protective shell, preventing the threads from being exposed and damaged over a long period of time. When the water outlet pipe needs to be used, flip the closed cover and push the protective shell to the rear end, and then press the insert upward to insert it into the slot, thereby fixing the position of the protective shell. The whole is simple to use and has a good protective effect.

[0015] 2. This utility model is equipped with a deceleration mechanism, which achieves the following when the insert is pulled down to leave the slot and the compressed spring rebounds to move the protective shell to the front end to restore its original position: the speed of the protective shell moving to the front end is also slowed down by the cooperation of components such as brackets and rollers, so as to prevent the speed from being too fast and hitting the operator.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6This utility model relates to an intelligent outdoor fire hydrant, comprising a fire hydrant body 1, a first straight pipe 2 fixedly mounted to the bottom of the fire hydrant body 1 by bolts, an alarm 3 installed at the front end of the first straight pipe 2, a water pressure sensor 4 installed on the side of the first straight pipe 2, a second straight pipe 5 fixedly mounted to the bottom of the first straight pipe 2 by bolts, a water flow meter 6 installed inside the second straight pipe 5, a wireless communication device 7 installed at the back end of the fire hydrant body 1, and a water outlet pipe 8 installed at the front end of the fire hydrant body 1. A protective mechanism 10 is installed at the end of the water outlet pipe 8 away from the fire hydrant body 1. 10 includes a chute 101, which is located at the bottom of the water outlet pipe 8. A slider 102 is slidably connected inside the chute 101. A protective shell 103 is fixedly connected to the end of the slider 102 away from the chute 101. A rotating shaft 104 is provided on the top of the protective shell 103. A sealing cover 105 is fixedly connected to the surface of the rotating shaft 104. A compression spring 106 is provided at the rear end inside the chute 101. A slot 107 is provided at the top inside the chute 101. A plug 108 is slidably connected through the bottom of the slider 102. A deceleration mechanism 11 is provided on both sides of the slider 102.

[0028] As shown in the figure, the water pressure sensor 4 and the water flow meter 6 are both electrically connected to the alarm 3 through built-in wires. The alarm 3 is electrically connected to the wireless communication device 7 through built-in wires. The water pressure sensor 4 detects the water pressure, and the water flow meter 6 detects the water flow. When there is a problem with the water pressure or water flow, a signal will be transmitted to the alarm 3 to light up the alarm. The alarm 3 then transmits a signal to the wireless communication device 7, which then reports to the fire hydrant management system.

[0029] As shown in the figure, the surface and inner wall of the water outlet pipe 8 are threaded, and the end of the water outlet pipe 8 away from the fire hydrant body 1 is threaded to a sealing cap 9. The inner wall thread of the water outlet pipe 8 is used for the installation of the sealing cap 9, and the surface thread of the water outlet pipe 8 is used for the connection of the water hose.

[0030] As shown in the figure, the diameter of the insertion post 108 is equal to the diameter of the slot 107, and the bottom of the insertion post 108 protrudes from the bottom of the protective shell 103, so that the insertion post 108 can be inserted into the slot 107.

[0031] As shown in the figure, the frictional force between the insert post 108 and the slider 102 is greater than the weight of the insert post 108 itself, and the weight of the insert post 108 itself will not cause it to move downward.

[0032] As shown in the figure, the deceleration mechanism 11 includes a bracket 111, which is fixedly connected to the side of the slider 102. A roller 112 is rotatably connected to the inner side of the bracket 111, and a deceleration strip 113 is fixedly connected to the surface of the roller 112.

[0033] As shown in the figure, the side of the roller 112 initially abuts against the inner wall of the slide 101. When the roller 112 moves with the slider 102, it will rub against the inner wall of the slide 101 and thus rotate.

[0034] A specific application of this embodiment is as follows: Water can flow through the second straight pipe 5 to the first straight pipe 2, then from the first straight pipe 2 to the fire hydrant body 1, and finally be discharged through the outlet pipe 8. The water pressure sensor 4 detects the water pressure, and the water flow meter 6 detects the water flow. When there is a problem with the water pressure or water flow, a signal is transmitted to the alarm 3 to activate the alarm. The alarm 3 transmits a signal to the wireless communication device 7, which then reports to the fire hydrant management system. When it is necessary to connect the water hose using the threaded connection on the surface of the outlet pipe 8, the sealing cover 105 is flipped over and the protective shell 103 is pushed to the rear end, compressing the compression spring 106. Then, the insertion post 108 is pressed upward to insert it into the slot 107, thereby fixing the position of the protective shell 103. Then, the water hose is connected to the fire hydrant through the threaded connection on the surface of the outlet pipe 8. The water hose is connected, and after the fire is extinguished, the insert 108 is pulled down to disengage it from the slot 107. At this time, the compression spring 106 rebounds and drives the protective shell 103 to move forward and return to its original position. The sealing cover 105 returns to its original position under the action of gravity. The protective shell 103 protects the water outlet pipe 8 and the threads on the surface of the water outlet pipe 8. The whole process is simple to use and has a good protective effect. When the roller 112 moves with the slider 102, it will rub against the inner wall of the slide 101 and rotate. The rotation of the roller 112 will drive the rubber deceleration strip 113 on its surface to continuously contact the inner wall of the slide 101. The resistance generated by the rubber deceleration strip 113 pressing against the inner wall of the slide 101 slows down the movement speed of the protective shell 103, preventing it from hitting the operator due to excessive speed and improving safety.
