[0002] The history of fluid measurement can be traced back to ancient times. For example, in the era of Caesar in ancient Rome, orifice plates were used to measure the amount of drinking water for residents. With the development of industry, fluid metering devices, as important instruments in industrial measurement, have placed increasingly higher requirements on the accuracy and range of flow measurement. Various types of flow meters have been introduced, from the initial orifice flowmeters and float flowmeters to the later electromagnetic flowmeters and vortex flowmeters. Fluid metering technology has continued to develop and improve.

[0003] Existing devices have some disadvantages during use. For example, existing fluid metering devices are generally fixed directly on certain devices, with a simple fixing structure and a complicated process, making it difficult to adapt to different application scenarios and needs. For example, when the height of the fluid metering device needs to be changed, it needs to be re-tightened, which wastes time and reduces the flexibility and adaptability of the equipment.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Example 1

[0020] like Figure 1 and Figure 4 As shown, the utility model provides a technical solution: a fluid metering device, comprising a protective shell 1, two protective doors 9 are provided at one end of the protective shell 1, hinges 91 are fixedly installed on both sides of the two protective doors 9, and the other side of the hinge 91 is fixedly connected to the protective shell 1, and handles 92 are rotatably installed at one end of the two protective doors 9, an outer shell 2 is provided inside the protective shell 1, and a limiting mechanism for fixing the outer shell 2 is provided on the inner wall of the protective shell 1, and a metering mechanism is provided inside the outer shell 2. During specific use, the outer shell 2 is first placed outside the inner part of the protective shell 1. Through the design of the fastening mechanism, the height of the outer shell 2 can be adjusted during specific implementation, and the outer shell 2 is fixed. Through the design of the metering mechanism, the flow rate of the fluid can be recorded, and the handle 92 is turned to open or close the protective shell 1, which can ensure that the outer shell 2 is not interfered with by external factors.

[0021] As an implementation method in this embodiment, Figure 2 Figure 3 and Figure 5As shown, the metering mechanism includes a limiting groove 71 opened inside the shell 2, and a first fixing rod 72 and a second fixing rod 75 are provided in the limiting groove 71. The outer walls on both sides of the first fixing rod 72 are fixedly connected to the shell 2, and the second fixing rod 75 passes through one end of the shell 2 horizontally. One end of the second fixing rod 75 is fixedly connected to the shell 2, and the other end of the second fixing rod 75 is fixedly installed with a flow sensor 4. The outer wall of the first fixing rod 72 is provided with a first runner 73, and the first runner 73 is rotatably connected to the first fixing rod 72. The outer wall of the second fixing rod 75 is provided with a second runner 74, and the second runner 74 is rotatably connected to the second fixing rod 75. The first runner 73 engages and rotates with the second runner 74. The outer wall of the shell 2 is fixedly installed with a first pipeline 7, and the other side wall of the shell 2 is fixedly installed with a second pipeline 76. The outer wall of the protective shell 1 is fixedly installed with two first joints 3, and the protective shell 1 is fixedly installed with two first joints 3. A second joint 31 is fixedly installed on one side wall, and a second pipeline 76 is fixedly installed on the other side wall of the shell 2. The interface of the first pipeline 7 is set to a funnel-shaped structure. During specific use, first, according to the specific implementation, it is determined whether the first pipeline 7 is connected to the upper first joint 3 or the lower first joint 3, that is, the water inlet end of the fluid metering. When the water flows into the limit groove 71 through the first pipeline 7, when the water flows into the first runner 73 and the second runner 74, the first runner 73 and the second runner 74 are driven to rotate. When the first runner 73 and the second runner 74 rotate, the flow sensor 4 is set to the FD-XA1 model, which can wirelessly sense and detect and display data. The interface of the first pipeline 7 is set to a funnel-shaped structure, which is convenient for cleaning and maintenance. In situations where impurities inside the pipeline need to be cleaned regularly, this design can greatly simplify maintenance work and improve maintenance efficiency.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the limiting mechanism includes two fixing plates 6, which are fixedly connected to the inner wall of the protective shell 1, and a slot 65 is provided at one end of the two fixing plates 6 away from the inner wall of the protective shell 1. Two sliding grooves 61 are provided inside the two fixing plates 6, and the two sliding grooves 61 pass through one end of the fixing plate 6 horizontally. A spring 62 is provided in the two sliding grooves 61, and the end of the spring 62 is fixedly connected to the fixing plate 6. The other end of the spring 62 is fixedly connected to a slide 63, and a block 66 is fixedly installed on the side wall of the slide 63. A pressing block 64 is fixedly installed on the other end of the slide 63. A third fixing rod 8 is fixedly installed on the back of the shell 2. The other end of the three fixing rods 8 is fixedly installed with an extrusion rod 81, and a groove 82 is provided on the side wall of the extrusion rod 81. The groove 82 is adapted to the size of the block 66. During specific use, the pressing block 64 is first pressed. When the pressing block 64 moves, the microphone moves. When the slide 63 moves, the spring 62 is squeezed and the spring 62 is deformed. The extrusion rod 81 is aligned with the slot 65 and inserted. At this time, the pressing block 64 is released, and the spring 62 will return to its initial state, thereby limiting and fixing the extrusion rod 81. When the position of the shell 2 needs to be adjusted, press the pressing block 64 and slide the shell 2 out.

[0023] Working principle: First, press the pressing block 64. When the pressing block 64 moves, the microphone moves. When the slide 63 moves, the spring 62 is squeezed. The spring 62 is deformed and the squeezing rod 81 is aligned with the slot 65 and inserted. At this time, release the pressing block 64 and the spring 62 will return to its initial state, thereby limiting and fixing the squeezing rod 81. When the housing 2 needs to be adjusted, press the pressing block 64 and slide the housing 2 out to limit the housing 2. According to the specific implementation, the first pipeline 7 and the first pipeline 8 are determined. The upper first connector 3 is connected to the lower first connector 3, that is, the water inlet end of the fluid metering. When the water flows into the limit groove 71 through the first pipe 7, when the water flows into the first runner 73 and the second runner 74, the first runner 73 and the second runner 74 are driven to rotate. When the first runner 73 and the second runner 74 rotate, the flow sensor 4 is set to the FD-XA1 model, which can wirelessly sense and detect and display data. The liquid flows through the first connector 3 through the detector, and the liquid flows out through the second connector 31.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
