[0024] The embodiment of the present application provides a turbine flowmeter that is easy to install, which effectively solves the problem that most of the existing turbine flowmeter shells are integrally formed and flanges are set at both ends. The flanges are connected to the pipeline. When the internal turbine assembly is damaged, it needs to be dismantled as a whole for repair. Since there are many flange connection bolts, it is not easy to dismantle and is relatively troublesome. Through the design of the turbine flowmeter body, operating window, arc piece, meter head, limit groove, limit bar, slider, slot and positioning rod, the movement of the two limit bars will drive the two groups of sliders to slide inside the two groups of limit grooves. At this time, the two positioning rods can be inserted into the other two slots to complete the limiting. At this time, the arc piece can be pulled out of the operating window, and the disassembly between the turbine flowmeter body and the meter head is completed. When the arc piece is removed, the impeller inside the turbine flowmeter body will be exposed to the outside, making maintenance more convenient and making the equipment easy to install and disassemble when in use.

[0025] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the problem that the existing turbine flowmeter housing is mostly integrally formed, and flanges are arranged at both ends, and the flanges are connected to the pipeline. When the internal turbine assembly is damaged, it needs to be dismantled as a whole for repair. Since there are many flange connection bolts, it is not easy to dismantle, which is a relatively troublesome technical problem. The overall idea is as follows: a turbine flowmeter that is easy to install includes a turbine flowmeter body 11, an operation window 12 is opened at the upper end of the turbine flowmeter body 11, a card slot 13 is opened in the inner wall of the operation window 12, an arc sheet 14 is placed inside the operation window 12, and a meter head 15 is fixedly installed at the upper end of the arc sheet 14;

[0026] Among them, a limit block 16 is arranged on the side wall of the arc-shaped piece 14, and the limit block 16 is built into the card slot 13. A sealing strip 17 is arranged on the side wall of the arc-shaped piece 14. When the device is installed, the arc-shaped piece 14 can be placed in the operation window 12, and the limit block 16 on the arc-shaped piece 14 will be inserted into the card slot 13. At this time, the connection can be completed by repeating the operation of step 1. At this time, the sealing strip 17 is subjected to the extrusion force to form a seal on the connection part, so that the connection sealing effect of the device is better when it is used, thereby ensuring the detection effect of the device on the water flow rate;

[0027] A fastening mechanism is symmetrically fixedly mounted on the turbine flowmeter body 11;

[0028] The fastening mechanism includes a fixing plate 21 , and two fixing plates 21 are fixedly mounted on the turbine flowmeter body 11 .

[0029] A first slide groove 22 is provided at the upper end of the two fixing plates 21, and a second slide groove 23 is provided inside the two fixing plates 21. The two second slide grooves 23 are respectively connected with the two first slide grooves 22, and the inner walls of the two second slide grooves 23 are symmetrically provided with limiting grooves 24. Limiting strips 25 are slidably installed inside the two second slide grooves 23, and sliders 26 are fixedly installed on the side walls of the two limiting strips 25. Two groups of sliders 26 are slidably arranged in the two groups of limiting grooves 24.

[0030] The upper ends of the two limit bars 25 are symmetrically provided with slots 27, and the two first slide grooves 22 are slidably installed with positioning rods 28, and the two positioning rods 28 are fixedly installed with springs 29. The ends of the two springs 29 away from the two positioning rods 28 are fixedly installed on the two fixing plates 21 respectively. When the device needs to be disassembled, the two positioning rods 28 can be pulled upwards at this time, and the two positioning rods 28 will be respectively drawn out from the two slots 27 and the first slide groove 22 under the movement of the two positioning rods 28. After the limit is released, the two limit bars 25 can be moved to both ends, and the movement of the two limit bars 25 will drive the two groups of sliders 26 to slide inside the two groups of limit grooves 24. At this time, the two positioning rods 28 can be inserted into the other two slots 27 to complete the limit. At this time, the arc piece 14 can be drawn out of the operating window 12, and then the disassembly between the turbine flowmeter body 11 and the meter head 15 is completed. When the arc piece 14 is disassembled, the impeller inside the turbine flowmeter body 11 will be exposed to the outside, making maintenance more convenient and making the device easy to install and disassemble when in use.

[0031] In view of the problems existing in the prior art, the utility model provides a turbine flowmeter which is easy to install. Through the design of the turbine flowmeter body 11, the operating window 12, the arc piece 14, the meter head 15, the limit groove 24, the limit bar 25, the slider 26, the slot 27 and the positioning rod 28, the movement of the two limit bars 25 will drive the two groups of sliders 26 to slide inside the two groups of limit grooves 24. At this time, the two positioning rods 28 can be inserted into the other two slots 27 to complete the limiting. At this time, the arc piece 14 can be pulled out of the operating window 12, and then the disassembly between the turbine flowmeter body 11 and the meter head 15 is completed. When the arc piece 14 is disassembled, the impeller inside the turbine flowmeter body 11 will be exposed to the outside, making maintenance more convenient and making the equipment easy to install and disassemble when in use.

[0032] Working principle:

[0033] In the first step, when the device needs to be disassembled, the two positioning rods 28 can be pulled upwards, and the two positioning rods 28 will be respectively drawn out from the two slots 27 and the first slide groove 22 under the movement. After the limit is released, the two limit bars 25 can be moved to both ends. The movement of the two limit bars 25 will drive the two groups of sliders 26 to slide inside the two groups of limit grooves 24. At this time, the two positioning rods 28 can be inserted into the other two slots 27 to complete the limit. At this time, the arc piece 14 can be drawn out of the operating window 12, and then the disassembly between the turbine flowmeter body 11 and the meter head 15 is completed. When the arc piece 14 is disassembled, the impeller inside the turbine flowmeter body 11 will be exposed to the outside, making maintenance more convenient and making the device easy to install and disassemble when in use;

[0034] In the second step, when the equipment is installed, the arc piece 14 can be placed in the operating window 12, and the limit block 16 on the arc piece 14 will be inserted into the card slot 13. The connection can be completed by repeating the operation of step one. At this time, the sealing strip 17 will be squeezed to form a seal on the connection part, so that the connection sealing effect of the equipment is better when it is used, thereby ensuring the detection effect of the equipment on the water flow rate.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
