[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0032] See also Figures 1 to 6 A turbine flowmeter provided by an embodiment of the utility model includes: a turbine flowmeter body 1, a display device 4 is installed on the arc surface of the turbine flowmeter body 1, an adjustment device 2 is provided at one end of the arc surface of the turbine flowmeter body 1, and an auxiliary device 3 is provided on the surface of the display device 4.

[0033] In the embodiments of the present invention, please refer to Figures 2 to 4The adjusting device 2 includes a fixed disk 201, which is fixedly connected to the turbine flowmeter body 1. A connecting block 202 is fixedly connected to one end of the fixed disk 201 away from the turbine flowmeter body 1. A connecting disk 203 is fixedly connected to the side of the connecting block 202 away from the turbine flowmeter body 1. A limiting block 204 is fixedly connected to one side of the connecting block 202. Both sides of the limiting block 204 are clamped with elastic frames 205. A filter screen 206 is fixedly connected to the inner wall of the elastic frame 205. Two connecting rods 207 are fixedly connected to one end of the arc surface of the elastic frame 205. The two connecting rods 207 are fixedly connected to one end away from the elastic frame 205. The same elastic block 208 is connected to the inner wall of the fixed plate 201, and the turbine flowmeter body 1 is connected to the pipeline. The turbine flowmeter body 1 can detect the flow velocity of the liquid in the pipeline. The value of the liquid flow velocity will be directly displayed by the display device 4. However, there are many impurities in the liquid inside the pipeline. This also causes the impurities to accumulate in the pipe body of the turbine flowmeter body 1 when the turbine flowmeter body 1 is used for a long time, thereby causing the turbine flowmeter body 1 to be blocked, affecting the accuracy of the turbine flowmeter body 1 in detecting the flow of the liquid in the pipeline. At this time, the adjusting device 2 can be used to adjust the flow velocity in the pipeline. The liquid is filtered to prevent impurities in the liquid from accumulating in the turbine flowmeter body 1, causing the turbine flowmeter body 1 to be blocked and affecting the detection. One end of the arc surface of the elastic frame 205 is fixedly connected to a telescopic rod 209, and the end of the telescopic rod 209 away from the elastic frame 205 is fixedly connected to a pull ring 210. When the elastic frame 205 and the filter screen 206 need to be pulled out from the limit block 204, the pull ring 210 installed on the telescopic rod 209 can be used to pull the elastic frame 205 and the filter screen 206 out. The pull ring 210 can increase the speed of pulling out the elastic frame 205 and the filter screen 206. The inner wall of the connecting plate 203 is fixedly connected to The connecting rod 211 has a fan blade 212 rotatably connected to its inner wall. When the liquid in the pipeline is filtered through the filter 206, the fan blade 212 on the connecting rod 211 will rotate under the circulation of the liquid, thereby forming a vortex in the liquid, and the impurities in the middle of the filter 206 can be swept to the edge of the filter 206, so that the fan blade 212 can prevent the filter 206 from being blocked. The limit block 204 is a titanium alloy block. The surface of the limit block 204 made of titanium alloy is relatively hard, which also makes the limit block 204 made of titanium alloy less likely to deform after long-term use and has a longer service life.

[0034] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary device 3 includes two protective shells 31, which are slidably connected to the two sides of the display device 4 respectively. A connecting plate 32 is fixedly connected to the side of the protective shell 31 away from the display device 4. Both ends of the connecting plate 32 are fixedly connected to a connecting block 33. The inner wall of each two connecting blocks 33 is slidably connected to the same sliding rod 34, and one end of the sliding rod 34 is fixedly connected to an elastic buckle 35. When the display device 4 is in use, the surface of the display device 4 can be protected by the auxiliary device 3. The auxiliary device 3 can prevent the display device 4 from being damaged by external collision. A card slot 36 is provided on one side of one connecting block 33 close to the elastic buckle 35. When the elastic block 208 contacts the connecting block 33, the card slot 36 provided on the connecting block 33 can improve the stability of the contact between the elastic block 208 and the connecting block 33, and provide a clamping effect between the two. The cross-section of the elastic buckle 35 is L-shaped. When the L-shaped elastic buckle 35 contacts the connecting block 33, its clamping effect is better, which is also the reason why the elastic buckle 35 and the connecting block 33 have strong stability.

[0035] The working principle of a turbine flowmeter provided by the utility model is as follows: when it is necessary to filter the liquid in the pipeline connected to the turbine flowmeter body 1, first squeeze the elastic frame 205, and move the deformed elastic frame 205 through the direction of the fixed disk 201 and the connecting disk 203 to the limit block 204 installed on the connecting block 202. Before the elastic frame 205 contacts the limit block 204, press the elastic block 208 on the connecting rod 207, and clamp the deformed elastic block 208 in the inner wall of the fixed disk 201. At this time, the deformed elastic frame 205 will contact the limit block 204, so that the filter screen 206 can be installed on the side of the turbine flowmeter body 1 by fixing the elastic frame 205 between the fixed disk 201 and the connecting disk 203. When the elastic frame 205 and the filter screen 206 are pulled out from the limit block 204, the pull ring 210 installed on the telescopic rod 209 can be used to pull out the elastic frame 205 and the filter screen 206. The pull ring 210 can increase the speed of pulling out the elastic frame 205 and the filter screen 206. When the liquid in the pipeline is filtered through the filter screen 206, the fan blades 212 on the connecting rod 211 will rotate under the circulation of the liquid, thereby forming a vortex in the liquid, and the impurities in the middle of the filter screen 206 can be swept to the edge of the filter screen 206, so that the fan blades 212 can prevent the filter screen 206 from being blocked. The surface of the limit block 204 made of titanium alloy is relatively hard, which also makes the limit block 204 made of titanium alloy less likely to deform after long-term use and has a longer service life.

[0036] When the display device 4 needs to be protected, the two protective shells 31 are connected to the two sides of the display device 4 respectively. After the two protective shells 31 are connected to the display device 4, the hole positions of the connecting blocks 33 installed on the connecting plates 32 are automatically aligned. At this time, the elastic buckle 35 is first pressed to deform the elastic buckle 35 on the sliding rod 34, and then the deformed elastic buckle 35 is pushed out of the second connecting block 33 through the first connecting block 33 through the sliding rod 34. When the elastic buckle 35 is pushed out of the second connecting block 33, the elastic buckle 35 It will automatically recover, so that the position of the sliding rod 34 can be limited by the recovered elastic buckle 35, so that the two protective shells 31 can be fixed on the display device 4 by the elastic buckle 35. When the elastic block 208 contacts the connecting block 33, the card slot 36 opened on the connecting block 33 can improve the stability of the contact between the elastic block 208 and the connecting block 33, and provide a card connection effect between the two. When the L-shaped elastic buckle 35 contacts the connecting block 33, its card connection effect is better, which is also the reason why the card connection between the elastic buckle 35 and the connecting block 33 is more stable.

[0037] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
