[0002] Flow measurement is one of the components of metrology science and technology. It is closely related to the national economy and scientific research and is widely used in various fields of the national economy such as metallurgy, chemical industry, petroleum, water service, food, agriculture, and environmental protection. Currently, there are various types of flow meters on the market, including electromagnetic flow meters, ultrasonic flow meters, volumetric flow meters, rotor flow meters, differential pressure flow meters, etc. When selecting a flow meter for adaptation, it is generally comprehensively considered from several aspects such as the performance of the flow meter instrument, fluid characteristics, installation conditions, environmental conditions, and economic factors. Among them, the installation conditions include: pipeline layout direction, flow direction, straight pipe section length on the upstream and downstream sides of the detection element, pipeline diameter, maintenance space, power supply, auxiliary equipment (filter), installation, etc.

[0003] Although there are various flow meters on the market, in the application scenario of intelligent fire hydrants, most intelligent plug manufacturers use existing flow meter products on the market for assembly. This method has some problems: since the existing flow meters are not specifically designed for intelligent fire hydrants, the wires are exposed, which affects the overall appearance of the intelligent plug and may also cause wire damage or faults. Summary of the Utility Model

[0004] Therefore, an intelligent plug flow meter is needed to solve the problem that the overall appearance of the intelligent plug is affected due to the wires being exposed because the existing flow meters are not specifically designed for intelligent fire hydrants.

[0006] The inner side wall of the flow inner liner encloses a hollow area that penetrates up and down. The flow inner liner is provided with a first installation groove, a second installation groove, and a third installation groove. The first installation groove and the second installation groove respectively communicate the inner side wall and the outer side wall of the flow inner liner. The third installation groove forms an opening on the outer side wall of the flow inner liner;

[0007] The ultrasonic flow meter includes a transmitter and a receiver. The transmitter is arranged in the first installation groove and is hermetically connected therebetween. The transmitter is connected to the third installation groove through a first wire penetrating into the opening.

[0068] Please refer to Figures 1 to 10 , this embodiment provides an intelligent plug flowmeter, including a flow inner tank 1, an ultrasonic flowmeter, and a packaging shell 2;

[0069] The inner side wall 113 of the flow inner liner 1 encloses a hollow area that runs through from top to bottom for the flow of water. The flow inner liner 1 is provided with a first installation groove 111, a second installation groove 112 and a third installation groove 121. The first installation groove 111 and the second installation groove 112 are respectively connected to the inner side wall 113 and the outer side wall of the flow inner liner 1. The third installation groove 121 has an opening 1211 formed on the outer side wall of the flow inner liner 1.

[0070] The ultrasonic flowmeter includes a transmitter and a receiver. The transmitter is arranged in the first installation groove 111 and is hermetically connected therebetween. The transmitter is connected to the third installation groove through a first wire passing through the opening 1211. The receiver is arranged in the second installation groove 112 and is hermetically connected therebetween. The receiver is connected to the third installation groove through a second wire passing through the opening 1211.

[0071] The encapsulation housing 2 is sleeved on the outer side wall of the flow inner liner 1. The inner side wall of the encapsulation housing 2 is provided with wire hole grooves 23 for the routing of the first wire and the second wire at positions corresponding to the first installation groove 111, the second installation groove 112 and the opening 1211. The interior of the encapsulation housing 2 is provided with a wire routing channel 24 for accommodating the first wire and the second wire. The encapsulation housing 2 is annularly arranged with a plurality of holes 25 that run through from top to bottom and are for the use of the first bolts.

[0072] Please refer to Figure 9 , generally, the fire hydrant 6 and the above-ground pipeline each carry a flange 61. Align the holes 25 of the flange 61 with the annularly arranged holes 25 on the encapsulation housing 2, and connect the fire hydrant 6, the encapsulation housing 2 and the above-ground pipeline through the first bolts. This way is convenient for installation and also convenient for later maintenance and repair.

[0073] When water flows through the hollow area of the flow inner liner 1, the ultrasonic signal is emitted by the transmitter and received by the receiver after passing through the water. The transmitter and the receiver are arranged to shoot at each other at a certain angle to ensure the normal operation of the ultrasonic flowmeter.

[0074] The first wire extends from the transmitter in the first installation groove 111, enters the encapsulation housing 2 through the wire hole groove 23 corresponding to the first installation groove 111, extends along the wire routing channel 24, enters the third installation groove 121 through the wire hole groove 23 corresponding to the opening 1211, and can finally be electrically connected to the detector. Similarly, the second wire extends from the receiver in the second installation groove 112, enters the encapsulation housing 2 through the wire hole groove 23 corresponding to the second installation groove 112, extends along the wire routing channel 24, enters the third installation groove 121 through the wire hole groove 23 corresponding to the opening 1211, and can finally be electrically connected to the detector.

[0075] By hiding the wires inside the encapsulation housing 2, the potential safety hazards caused by the exposure of the wires are avoided. Such a design also makes the overall appearance of the intelligent hydrant flowmeter neater and more beautiful.

[0076] Please refer to Figures 2 to 5 In this embodiment, the encapsulation housing 2 includes an upper housing 21 and a lower housing 22. The upper housing 21 and the lower housing 22 face each other up and down and are detachably connected. A wire routing channel 24 and a wire hole groove 23 are provided on the upper housing 21 and / or the lower housing 22. The wire routing channel 24 and the wire hole groove 23 can be provided on the upper housing 21, or the wire routing channel 24 and the wire hole groove 23 can be provided on the lower housing 22, or the wire routing channel 24 and the wire hole groove 23 are jointly formed between the upper housing 21 and the lower housing 22. Figure 4 As shown, the wire routing channel 24 and the wire hole groove 23 are provided on the lower housing 22, and the first wire and the second wire are located inside the lower housing 22. The encapsulation housing 2 is divided into upper and lower parts. When assembling the upper housing 21 and the lower housing 22, it can be ensured that the first wire and the second wire are safely encapsulated.

[0077] Please refer to Figure 6 In this embodiment, both the upper housing 21 and the lower housing 22 are connected to the flow inner bladder 1 through a sliding limit structure 4, ensuring that the upper housing 21 and the lower housing 22 are quickly and accurately installed in place, improving the assembly efficiency.

[0078] Please refer to Figures 1 to 6 In this embodiment, first limit protrusions 41 are provided on the inner side wall 211 of the upper housing 21, and first limit sliding grooves 42 adapted to the first limit protrusions 41 are provided on the outer side wall of the flow inner bladder 1. The first limit sliding grooves 42 extend to the upper end surface of the flow inner bladder 1. The first limit protrusions 41 and the first limit sliding grooves 42 form a sliding limit structure 4, and the structure is as shown in Figures 1 to 3 ;

[0079] Second limit protrusions 43 are provided on the inner side wall 221 of the lower housing 22, and second limit sliding grooves 44 adapted to the second limit protrusions 43 are provided on the outer side wall of the flow inner bladder 1. The second limit sliding grooves 44 extend to the lower end surface of the flow inner bladder 1. The second limit protrusions 43 and the second limit sliding grooves 44 form a sliding limit structure 4, and the structure is as shown in Figure 1 、 Figures 4 to 5 ;

[0080] When the upper housing 21 is installed, the first limit protrusions 41 thereon slide down along the first limit sliding grooves 42 above the flow inner bladder 1 until in place, which is convenient for alignment. When the lower housing 22 is installed, the second limit protrusions 43 thereon slide up along the second limit sliding grooves 44 below the flow inner bladder 1 until in place, which is convenient for alignment. After the upper housing 21 and the lower housing 22 are both installed in place, the lower end surface of the upper housing 21 contacts the upper end surface of the lower housing 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 housing 21 and the lower housing 22 are in close contact.

[0081] Please refer to Figures 1 to 6 , in this embodiment, on the outer side wall of the flow inner container 1, there is a reinforcing rib 45 protruding and extending vertically. At the positions of the inner side walls of the upper outer shell 21 and the lower outer shell 22 corresponding to the reinforcing rib 45, there are third limiting sliding grooves 46. The reinforcing rib 45 and the third limiting sliding grooves 46 form a sliding limiting structure 4. When the upper outer shell 21 is installed, the third limiting sliding groove 46 thereon slides downward along the reinforcing rib 45 until in place, which is convenient for alignment. When the lower outer shell 22 is installed, the third limiting sliding groove 46 thereon slides upward along the reinforcing rib 45 until in place, 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.

[0082] In this embodiment, the upper outer shell 21 and the lower outer shell 22 are detachably connected by second bolts, and the screw holes 28 corresponding to the second bolts are as Figures 2 to 5 shown. By hiding the wires in the wiring channel 24 between the encapsulated upper outer shell 21 and the lower outer shell 22, and ensuring the tight connection of the encapsulated shell 2 through the second bolts, the safety hazards and unsightly problems caused by the exposure of the wires are avoided.

[0083] Please refer to Figure 4 , in this embodiment, the hole 25 and the wiring channel 24 are partitioned. The outer side wall of the hole 25 in the flow inner container 1 has a transition notch 26, and the transition notch 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 wires, the hole 25 and the wiring channel 24 are designed to be partitioned, 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 sealed shell, the hole 25 almost occupies the width of the sealed shell. To facilitate the routing of the first wire and the second wire, a transition notch 26 is provided on the outer wall of the hole 25, and the transition notch 26 is not communicated with the inside of the hole 25, which can better allow the wires to pass through.

[0084] Please refer to Figure 7 , in this embodiment, the intelligent plug flowmeter further includes a sealing ring 5. The sealing ring 5 is arranged on the upper end surface of the flow inner container 1 and is used to seal the lower end surface of the intelligent plug and the upper end surface of the flow inner container 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. When the intelligent plug is connected to the flowmeter, the sealing ring 5 is compressed to form a tight sealing layer to prevent external substances such as moisture and dust from entering the inside of the flow inner container 1.

[0085] Please refer to Figure 1 and Figure 8, in this embodiment, a weight-reducing hole 13 is provided on the upper end surface of the flow inner liner 1 and is recessed inward. At the position corresponding to the weight-reducing hole 13 on the lower end surface of the sealing ring 5, a protruding block 51 protrudes downward. The protruding block 51 is inserted into the weight-reducing hole 13. The weight-reducing hole 13 can reduce the weight of the flow inner liner 1 and at the same time provide a positioning and fixing structure for the protruding block 51 of the sealing ring 5. Specifically, when the intelligent bolt is connected to the flow inner liner 1, the protruding block 51 of the sealing ring 5 will be inserted into the weight-reducing hole 13. This matching method not only ensures the accurate position of the sealing ring 5, but also increases the contact area between the sealing ring 5 and the flow inner liner 1, ensuring the stability and sealing effect of the sealing ring 5.

[0086] In this embodiment, the flow inner liner 1 is made of professional engineering materials so that it can bear more than six hundred catties, ensuring that this intelligent bolt flowmeter can work normally when installed on the fire hydrant 6.

[0087] Please refer to Figures 1 to 6 , in this embodiment, the flow inner liner 1 includes an integrally formed annular structure 11 and a rectangular structure 12, and the structure is as Figure 1 and Figure 6 shown. The inner circle of the annular structure 11 is the inner side wall 113 of the flow inner liner 1. The annular structure 11 is provided with a first installation groove 111 and a second installation groove 112. A third installation groove 121 is provided inside the rectangular structure 12; the shape of the encapsulation housing 2 is a broken circular ring, and the structure is as Figures 2 to 6 shown. When the encapsulation housing 2 is sleeved on the outer side wall of the flow inner liner 1, its disconnected position 27 accommodates the rectangular structure 12, ensuring that the encapsulation housing 2 can completely cover the flow inner liner 1.

[0088] Please refer to Figure 1 , in this embodiment, the third installation groove 121 has an opening 1212 at one end of the rectangular structure 12 away from the annular structure 11, and a partition 3 is provided inside the opening 1212. The third installation groove 121 has an opening 1211 on each of the left and right side walls of the rectangular structure 12. One opening 1211 is for the first wire to enter, and the other opening 1211 is for the second wire to enter.

[0089] Please refer to Figures 2 to 5 , in this embodiment, the encapsulation housing 2 is an axisymmetric structure, and the first wire and the second wire can be routed separately on both sides of the encapsulation housing 2. The routing channel 24 is on the lower housing 22, as Figure 4 shown. The first wire can enter a part of the routing channel 24 through the first wire hole groove 23, pass through the first transition notch 26 during this period, and enter the first opening 1211 through the second wire hole groove 23. The second wire can enter another part of the routing channel 24 through the third wire hole groove 23, pass through the second transition notch 26 during this period, and enter the second opening 1211 through the fourth wire hole groove 23.

[0090] The sealed connection between the transmitter and the first installation groove and the sealed connection between the receiver and the second installation groove in the above embodiments can be achieved through sealing with a sealing ring or through sealing with sealant. When using a sealing ring, as Figure 10 shown, taking the first installation groove 111 and the transmitter 1111 as an example, the receiver can refer to the same setting. The transmitter 1111 has a first wire 1112. The flow inner tank 1 is provided with a card slot 1113 at the first installation groove 111, and there is a corresponding buckle 1114. A wire groove 1115 for passing the wire is provided in the middle of the buckle 1114. A sealing ring 1116 is provided on the outer periphery of the transmitter 1111. When making a sealed connection, the transmitter 1111 together with the sealing ring is inserted into the first installation groove 111. The diameter of the first installation groove 111 is slightly smaller than the outer diameter of the sealing ring after it is installed on the transmitter 1111 to achieve an interference sealing fit. Then, the buckle 1114 is inserted into the card slot 1113 to fix the transmitter 1111 in the first installation groove 111, playing a role in fixing and sealing. When using sealant, it can be applied to the positions of the first installation groove 111 and the second installation groove 112 to ensure that the useless gaps between the transmitter, the receiver and the flow inner tank 1 are closed (but do not affect the wire from protruding), avoiding potential safety hazards caused by water leakage.
