[0036] Please refer to Figures 1 to 7, this embodiment provides a sleeve-type flowmeter dedicated to an intelligent bolt, including a cylinder main body 10 and at least a pair of transducers 20. The diameter of the cylinder body of the cylinder main body 10 is smaller than the diameters of both ends. At least a pair of inclined structural grooves 101 are provided on the side wall of the cylinder body. The structural grooves 101 penetrate through the cylinder body and are used to inlay the transducers 20. When a pair of transducers 20 are respectively inlaid in a pair of structural grooves 101, the ultrasonic path between the transmitting end and the receiving end passes through the center of a certain cross-section of the cylinder body. The pair of transducers 20 transmit digital signals to an external signal processing module through signal lines. The signal processing module can be a separate converter, and the water flow rate data is obtained by converting the digital signal through the converter. The signal processing module can also be integrated into the main control module of the intelligent fire hydrant. The transducer 20 is connected to the main control module, and the digital signal is directly processed by the main control module to obtain the water flow rate data.

[0037] The size of the cylinder main body 10 should match the specifications of the bottom pipe of the fire hydrant, that is, the diameters of both ends of the cylinder main body 10 are slightly smaller than the inner diameter of the bottom pipe of the fire hydrant, so that the cylinder main body 10 can be inserted into the bottom pipe of the fire hydrant. At the same time, since the diameter of the cylinder body of the cylinder main body 10 is smaller than the diameters of both ends, there is a certain space between the cylinder body of the cylinder main body 10 and the inner wall of the bottom pipe of the fire hydrant. This space can be used to set relevant structures and the wiring of the transducer 20. It should be noted that the signal line of the transducer 20 can be led to the outside through a waterproof joint provided on the wall of the bottom pipe of the fire hydrant, and is electrically connected to the main control module of the intelligent fire hydrant through the waterproof joint.

[0038] The transducer 20 is the ultrasonic transducer 20 used in a conventional ultrasonic flowmeter. Taking a pair of transducers 20 as a group, in a group of transducers 20, one is the ultrasonic transmitting end and the other is the ultrasonic receiving end. The working principle of measuring the water flow rate by the transducer 20 is mainly based on the relationship between the propagation speed of ultrasonic waves in the fluid and the fluid flow rate. When ultrasonic waves propagate in the fluid, their propagation speed will be affected by the fluid velocity. Therefore, by detecting the received ultrasonic signal, the fluid flow velocity can be measured, and then the fluid flow rate can be obtained. The working principle of the ultrasonic flowmeter includes various methods, and the most common one is the propagation speed method. It uses the change in the propagation speed of ultrasonic waves in the fluid in the downstream and upstream directions to measure the fluid flow velocity, and then obtains the flow rate flowing through the pipeline.

[0039] The supporting structure of the structural groove 101 extends obliquely inward from the inner wall of the cylinder body 10, that is, the structural groove 101 protrudes from the inner wall surface of the cylinder body 10, and the protruding height only needs to meet the requirement of being able to completely expose the transmitting end or receiving end of the transducer 20, that is, only need to ensure that ultrasonic signals can be stably transmitted and received between the two transducers 20. Since the common housing of the existing ultrasonic transducer 20 is cylindrical, from the perspective of economic practicality, setting the structural groove 101 to be inclined is applicable to the existing transducer 20, with stronger economic applicability.

[0040] It should also be noted that a waterproof structure, such as a waterproof gasket, can be provided at the notch of the structural groove 101. By filling the gap between the front end of the transducer 20 and the structural groove 101 with the waterproof gasket, it is ensured that the transducer 20 is firmly installed and will not shake and cause the transducer to fall off.

[0041] This new type consists of a cylinder body 10 and at least a pair of transducers 20. The transducers 20 are assembled inside the cylinder body 10, and the transducers 20 are arranged to emit in opposite directions at a certain angle to ensure the normal transmission of ultrasonic signals. The signal wires of the transducers 20 are converged into a single bus outside the cylinder body 10. The bus passes through a waterproof connector to realize the wiring from the inside to the outside of the fire hydrant, and is connected and communicated with the main control module on the basis of ensuring waterproof sealing, while realizing the functions of water flow measurement, statistics and reporting.

[0042] In order to facilitate the assembly of the transducer 20, the transducer 20 needs to be pushed in from the bottom of the structural groove 101, and an additional structure is required to ensure that the transducer 20 can remain stable after being embedded in the structural groove 101, and to ensure that the ultrasonic wave will not deviate. Therefore, in some embodiments, a rear cover assembly 30 is also included, and the rear cover assembly 30 is arranged at the structural groove 101 on the outer wall of the barrel of the barrel body 10, and is used to resist the rear end of the transducer 20. The rear cover assembly 30 is detachably connected to the barrel body 10, such as a snap-on slot connection, a slider slot connection or a fastener connection, and the connection is stable and convenient for disassembly. Specifically, the rear cover assembly 30 includes a cover plate 301 and a structural member 302, and an opening 3012 is provided in the middle of the cover plate 301, and a through groove 3011 extends from the opening to one side of the cover plate 301, and the structural member 302 is used to embed the opening and resist the rear end of the transducer 20. The signal line of the transducer 20 can be routed along the through groove 3011 to the outside of the tube body 10. Furthermore, an inner groove 3021 is provided in the structural member 302. When the structural member 302 is embedded in the opening of the cover plate 301, the inner groove 3021 is connected with the through groove 3011. The structural member 302 is pressed against the rear end of the transducer 20 to further improve the stability of the transducer 20. At the same time, the signal line is accommodated by the inner groove 3021 to ensure that the signal line will not be over-pressed to cause signal interruption. Furthermore, a plurality of limit strips 3022 are provided on the structural member 302, and the plurality of limit strips 3022 are respectively arranged on the top or side of the structural member 302. The limit strips 3022 respectively clamp the front and back surfaces of the cover plate 301 to improve the combination stability of the structural member 302 and the cover plate 301.

[0043] In some embodiments, a plurality of structural bars 102 are provided on the outer wall of the cylinder body of the cylinder body 10. The structural bars 102 are oriented horizontally and vertically and are perpendicular to the tangent of the cylinder body 10. By providing the structural bars 102, the overall strength of the cylinder body 10 is effectively improved to ensure that it is not damaged by water pressure.

[0044] In some embodiments, a plurality of the structural strips 102 enclose a wire collection area 103, and the signal lines of a plurality of transducers 20 are collected into a bus in the wire collection area 103. The wire collection area 103 is provided to accommodate the intersection of a plurality of signal lines and the bus, and a cover body can be provided for storage, thereby improving neatness and aesthetics.

[0045] In some embodiments, a notch 104 is provided at the upper edge of the barrel body 10, and the notch 104 is used for the bus bar to pass through. The size of the notch 104 matches the bus bar.

[0046] In some embodiments, the structural bar 102 is provided with a through hole 105, and the through hole 105 is used for passing the signal line of the transducer 20. The through hole 105 facilitates the routing of the signal line, making the overall appearance more beautiful.

[0047] It should be noted that although the above embodiments have been described in this text, it does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present utility model.
