Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a backpack-type intelligent hydrant. Background Art

[0002] Existing outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They are mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing, and can also be directly connected to a hose and a water gun to spray water for fire extinguishing. They are one of the important fire-fighting facilities for extinguishing fires. Due to their wide distribution, installation outdoors, and easy use, they are prone to being damaged and stolen of water. For example, a fire hydrant is knocked down by a vehicle impact, resulting in long-term loss of pipeline water; illegal use of fire hydrant water resources for temporary construction, landscaping, vehicle washing, etc. The existing supervision measures for fire hydrants mainly rely on the inspection by water company inspectors and reports from the public. For the widely distributed and large number of outdoor fire hydrants, the supervision means are single, weak, and the supervision is not in place. Content of the Utility Model

[0056] Please refer toFigures 1 to 12 , this embodiment provides a backpack - type intelligent fire hydrant, including:

[0057] A fire hydrant 6, the water inlet of the fire hydrant 6 is provided with a flange 61 for connecting with a remote Internet of Things monitoring module; and

[0058] The remote Internet of Things monitoring module, the remote Internet of Things monitoring module includes a flowmeter device, a backpack 8, a battery 7 and a controller 9. The flowmeter device includes a housing, an ultrasonic flowmeter and a water pressure sensor. The inner side wall 113 of the housing encloses a hollow area that penetrates up and down. The hollow area is communicated with the water inlet. The housing has a flange structure adapted to the flange 61. The flange structure and the flange 61 are connected by bolts (first bolts). An ultrasonic flowmeter and a water pressure sensor 101 are arranged in the housing. The ultrasonic flowmeter is used to detect the flow velocity information and flow rate information of the water flowing through the hollow area. The ultrasonic flowmeter and the water pressure sensor are connected to the controller 9. The controller 9 is used to judge whether the fire hydrant is using water according to the flow velocity information and flow rate information. The ultrasonic flowmeter and the controller 9 are respectively connected to the battery 7. The backpack 8 is arranged on the fire hydrant 6 through a pipe clamp 81. The backpack 8 is provided with a controller 9 and a battery 7. Among them, the backpack 8 is provided with a through - hole 82 through which a third wire harness for connecting between the ultrasonic flowmeter, the controller and the battery passes. The water pressure sensor 101 is fixed in the through - hole after a through - hole is arranged on the housing, so as to be in contact with the water flowing through the middle of the housing, thereby realizing water pressure detection. The water pressure sensor 101 can be hermetically connected to the through - hole by using sealant or a sealing ring, as Figure 12 shown.

[0059] The ultrasonic flowmeter is installed in the housing and is used to measure the flow velocity and total amount of water. The controller 9 is responsible for processing the data of the ultrasonic flowmeter and judging whether the fire hydrant 6 is in use based on these data. The battery 7 powers the entire monitoring module. The backpack 8 is installed on the fire hydrant 6 through a pipe clamp 81 and is used to accommodate the controller 9 and the battery 7. The backpack 8 is designed with a through - hole 82 so that the third wire harness can pass through to connect each electrical component.

[0060] The backpack - type intelligent fire hydrant can be installed on an existing fire hydrant through simple steps without major transformation of the original facilities. The housing of the flowmeter device can be installed between the middle section of the fire hydrant and the underground pipeline by means of flange connection. Align the holes of the flange 61 with the holes 25 arranged in a ring on the housing, and form a connection among the fire hydrant 6, the housing and the above - ground pipeline through the first bolts. Then fasten the backpack 8 on the fire hydrant 6 through the pipe clamp 81. This way is convenient for installation and also convenient for later maintenance and repair.

[0061] When water flows through the fire hydrant 6, the ultrasonic flowmeter measures the water flow velocity and flow rate through the hollow area, and transmits the measurement data to the controller 9. The controller 9 determines whether the fire hydrant 6 is in use according to a preset threshold. If abnormal use is detected (such as an abnormal increase in flow rate), the controller 9 will trigger an alarm and send a notification to the management personnel through the wireless network. After receiving the notification, the management personnel can take timely measures, such as closing the water source, dispatching staff to conduct on-site inspections, etc. By monitoring the usage of the fire hydrant 6 in real time, the situation of illegal theft can be effectively reduced, and water resource waste can be reduced.

[0062] In this embodiment, the backpack-type intelligent hydrant further includes a management platform, and the management platform and the controller can communicate with each other by using the NB-IOT communication method. Of course, other communication methods can also be used. When the working parameters of relevant sensors exceed the preset threshold, the device actively reports the alarm information to the management platform.

[0063] In this embodiment, the controller can select a microcontroller unit (MCU) as the core control component, which can provide stronger data processing capabilities to ensure the accuracy and timeliness of data.

[0064] In this embodiment, the battery 7 is a lithium battery. Using a lithium battery as the power source, compared with other types of batteries, the lithium battery has a higher energy density and a longer service life, thus ensuring the stable operation of the system.

[0065] In this embodiment, the backpack 8 is in the shape of a cuboid and is made of a hard material, which can provide better physical protection, prevent damage caused by accidental collisions, and can be used for a long time in a harsh outdoor environment.

[0066] In this embodiment, the battery 7 and the controller 9 are arranged behind a controller housing and then fastened in the backpack 8. The controller housing can be a cubic housing and can be a transparent housing. After the battery and the controller are placed behind the controller housing, the controller housing is then placed into the backpack, which can realize the overall fixation of the battery 7 and the controller 9. Optionally, a clamping structure 83 for fixing the controller housing is provided in the backpack. The clamping structure 83 limits the position from the outside of the controller housing, which can reduce the friction and collision between internal components and extend the service life.

[0067] In this embodiment, the housing includes a flow inner liner 1 and a packaging outer shell 2. The inner side wall 113 of the flow inner liner 1 encloses a hollow area for the flow of water. The flow inner liner 1 is provided with a first assembly hole 111, a second assembly hole 112 and a third assembly hole 121. The first assembly hole 111 and the second assembly hole 112 respectively communicate the inner side wall 113 and the outer side wall of the flow inner liner 1. The third assembly hole 121 forms an opening 1211 on the outer side wall of the flow inner liner 1;

[0068] The ultrasonic flowmeter includes a transmitter, a receiver and a flow detector. The transmitter is arranged in the first assembly hole 111 and is hermetically connected therebetween. The transmitter is connected to the third assembly hole through the first wire harness passing through the opening 1211. The receiver is arranged in the second assembly hole 112 and is hermetically connected therebetween. The receiver is connected to the third assembly hole through the second wire harness passing through the opening 1211.

[0069] The encapsulation housing 2 is sleeved on the outer side wall of the flow inner container 1. The inner side wall of the encapsulation housing 2 is provided with wire grooves 23 for the first wire harness and the second wire harness to run at positions corresponding to the first assembly hole 111, the second assembly hole 112 and the opening 1211. The encapsulation housing 2 is internally provided with a wire channel 24 for accommodating the first wire harness and the second wire harness. The encapsulation housing is provided with a flange structure.

[0070] In this embodiment, the flange structure includes a plurality of holes 25, and the plurality of holes 25 are arranged in a circular pattern and can be used for connecting with the flange plate 61. The holes 25 communicate with the upper end surface and the lower end surface of the encapsulation housing 2.

[0071] When water flows through the hollow area of the flow inner container 1, the ultrasonic signal is emitted by the transmitter and received by the receiver after passing through the water flow. The transmitter and the receiver are arranged to emit in a certain angle to ensure the normal operation of the ultrasonic flowmeter.

[0072] The hermetic connection between the transmitter and the first assembly hole and the hermetic connection between the receiver and the second assembly hole in the above embodiment can be connected by sealing with a sealing ring or by sealing with sealant. When using a sealing ring, as Figure 10 shown, taking the first assembly hole and the transmitter as an example, the receiver can refer to the same setting. The transmitter has a first wire harness. The flow inner container is provided with a clamping groove at the first assembly hole, and there is a corresponding clamping member. A wire groove for passing the wire harness is arranged in the middle of the clamping member. A sealing ring is arranged on the outer periphery of the transmitter. The transmitter and the sealing ring are embedded into the first assembly hole by an interference fit manner, and then the clamping member is inserted into the clamping groove to realize the fixation of the transmitter. When using sealant, it can be applied at the positions of the first assembly hole and the second assembly hole to ensure that the useless gaps between the transmitter, the receiver and the flow inner container are closed (but does not affect the wire harness extending out), and avoid the safety hazards caused by water leakage.

[0073] The first wire harness extends from the transmitter in the first assembly hole 111, enters the encapsulation housing 2 through the wire routing groove 23 corresponding to the first assembly hole 111, extends along the wire routing channel 24, enters the third assembly hole 121 through the wire routing groove 23 corresponding to the opening 1211, and can finally be electrically connected to the detector. Similarly, the second wire harness extends from the receiver in the second assembly hole 112, enters the encapsulation housing 2 through the wire routing groove 23 corresponding to the second assembly hole 112, extends along the wire routing channel 24, enters the third assembly hole 121 through the wire routing groove 23 corresponding to the opening 1211, and can finally be electrically connected to the flow detector.

[0074] By hiding the wire harness inside the encapsulation housing 2, the safety hazards caused by the exposure of the wire harness are avoided, and such a design also makes the overall appearance strength of the intelligent bolt stronger.

[0075] Please refer to Figures 5 to 8 , in this embodiment, the encapsulation housing 2 includes an upper encapsulation shell 21 and a lower encapsulation shell 22. The upper encapsulation shell 21 and the lower encapsulation shell 22 are opposite to each other up and down and are detachably connected. The wire routing channel 24 and the wire routing groove 23 are provided on the upper encapsulation shell 21 and / or the lower encapsulation shell 22. The wire routing channel 24 and the wire routing groove 23 can be provided on the upper encapsulation shell 21, or the wire routing channel 24 and the wire routing groove 23 can be provided on the lower encapsulation shell 22, or the wire routing channel 24 and the wire routing groove 23 are jointly formed between the upper encapsulation shell 21 and the lower encapsulation shell 22. Figure 4 As shown, the wire routing channel 24 and the wire routing groove 23 are provided on the lower encapsulation shell 22, and the first wire harness and the second wire harness are located inside the lower encapsulation shell 22. By dividing the encapsulation housing 2 into upper and lower parts, when assembling the upper encapsulation shell 21 and the lower encapsulation shell 22, it can be ensured that the first wire harness and the second wire harness are safely encapsulated.

[0076] Please refer to Figure 9 , in this embodiment, both the upper encapsulation shell 21 and the lower encapsulation shell 22 are connected to the flow inner bladder 1 through the sliding limit structure 4, ensuring that the upper encapsulation shell 21 and the lower encapsulation shell 22 are quickly and accurately installed in place, and improving the assembly efficiency.

[0077] Please refer to Figures 4 to 9 , in this embodiment, first bumps 41 are provided on the inner side walls 211 of the upper encapsulation shell 21, and first sliding grooves 42 adapted to the first bumps 41 are provided on the outer side wall of the flow inner bladder 1. The first sliding grooves 42 extend to the upper end face of the flow inner bladder 1, and the first bumps 41 and the first sliding grooves 42 form the sliding limit structure 4, and the structure is as Figures 4 to 7 shown;

[0078] The inner side wall 221 of the lower encapsulation shell 22 is provided with a second convex block 43, and the outer side wall of the flow inner container 1 is provided with a second sliding groove 44 adapted to the second convex block 43. The second sliding groove 44 extends to the lower end surface of the flow inner container 1. The second convex block 43 and the second sliding groove 44 form a sliding limit structure 4, and the structure is as shown in Figure 5 , Figures 7 to 8 shown.

[0079] When the upper encapsulation shell 21 is installed, the first convex block 41 thereon slides downward along the first sliding groove 42 above the flow inner container 1 until it reaches the position, which is convenient for alignment. When the lower encapsulation shell 22 is installed, the second convex block 43 thereon slides upward along the second sliding groove 44 below the flow inner container 1 until it reaches the position, which is convenient for alignment. After both the upper encapsulation shell 21 and the lower encapsulation shell 22 are installed in place, the lower end surface of the upper encapsulation shell 21 contacts the upper end surface of the lower encapsulation shell 22, and the connection between the two can be realized through a detachable structure (such as the second bolt mentioned below), so that the upper encapsulation shell 21 and the lower encapsulation shell 22 are in close contact.

[0080] Please refer to Figures 4 to 9 , in this embodiment, the outer side wall of the flow inner container 1 is provided with a reinforcing rib 45 protruding and extending up and down. The inner side walls of the upper encapsulation shell 21 and the lower encapsulation shell 22 are provided with a third sliding groove 46 corresponding to the position of the reinforcing rib 45. The reinforcing rib 45 and the third sliding groove 46 form a sliding limit structure 4. When the upper encapsulation shell 21 is installed, the third sliding groove 46 thereon slides downward along the reinforcing rib 45 until it reaches the position, which is convenient for alignment. When the lower encapsulation shell 22 is installed, the third sliding groove 46 thereon slides upward along the reinforcing rib 45 until it reaches the position, which is convenient for alignment. At the same time, the reinforcing rib 45 can enhance the structural strength of the flow inner container 1 itself.

[0081] In this embodiment, the upper encapsulation shell 21 and the lower encapsulation shell 22 are detachably connected by a second bolt, and the screw holes 28 corresponding to the second bolt are as shown in Figures 5 to 8 shown. By hiding the wire harness in the wiring channel 24 between the upper encapsulation shell 21 and the lower encapsulation shell 22 and ensuring the tight connection of the encapsulation shell 2 through the second bolt, the safety hazards and unsightly problems caused by the exposure of the wire harness are avoided.

[0082] Please refer to Figure 7, in this embodiment, the hole 25 is arranged separately from the wiring channel 24. The hole 25 has a transition port 26 on the outer wall in the flow inner liner 1, and the transition port 26 serves as a part of the wiring channel 24. The hole 25 is mainly used for installing the first bolt to connect the fire hydrant 6 and the flowmeter. To ensure the safety and concealment of the wiring harness, the hole 25 and the wiring channel 24 are designed to be separated, that is, they are independent of each other in space and do not affect the strength of the wall of the hole 25. Due to the size limitation of the sealing housing, the hole 25 almost occupies the width of the sealing housing. To facilitate the wiring of the first wiring harness and the second wiring harness, a transition port 26 is provided on the outer wall of the hole 25, and the transition port 26 is not connected to the inside of the hole 25, which can better allow the wiring harness to pass through.

[0083] Please refer to Figure 10 , in this embodiment, the intelligent bolt further includes a sealing ring 5. The sealing ring 5 is arranged on the upper end surface of the flow inner liner 1 and is used to seal the lower end surface of the intelligent bolt and the upper end surface of the flow inner liner 1. The sealing ring 5 is usually made of materials with good elasticity and chemical resistance, such as silicone rubber, fluororubber, etc., to ensure good sealing performance under different environmental conditions.
