In order to prevent over-irrigation, ultrasonic flow meters are needed to accurately measure the amount of irrigation water.

[0003] When the ultrasonic flow meter is installed outdoors, it is directly exposed to the outside. Therefore, when encountering severe weather such as hail and strong winds, the hail or stones blown by the strong wind will directly hit the ultrasonic flow meter, which can easily cause damage to the display screen and casing of the ultrasonic flow meter, that is, it will shorten the service life of the ultrasonic flow meter to a certain extent. For this reason, we propose a water metering device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A water metering device includes a flow meter 1, and a mounting pipe 2 is connected to the bottom end of the flow meter 1. The metering principle of the flow meter 1 and the mounting pipe 2 is the existing technology, which will not be described in detail here. A first protective cover 3 is fixedly provided at the bottom end of the flow meter 1, and a second protective cover 4 is provided above the first protective cover 3. The second protective cover 4 and the first protective cover 3 are symmetrically connected to a docking block 5 on the side close to each other, and the docking blocks 5 are connected by bolts. When in use, the first protective cover 3 and the flow meter 1 are fixedly connected, and the second protective cover 4 is movably connected to the flow meter 1. Through the coordinated use of the two, the flow meter 1 can be fully protected. When the flow meter 1 needs to be repaired, the staff can remove the bolts set between the upper and lower groups of docking blocks 5, thereby realizing the disassembly of the second protective cover 4 and the first protective cover 3, so as to realize the repair work of the flow meter 1.

[0024] Further, see Figure 1 , Figure 3 and Figure 4 It can be known that a transparent plate 6 is engaged with the top of the second protective cover 4, and sliders 7 are symmetrically connected to both sides of the transparent plate 6. A slide 8 adapted to the slider 7 is provided on the inner wall of the second protective cover 4, and a spring 9 is connected to the inner wall of the slide 8. The other end of the spring 9 is fixedly connected to the slider 7. When in use, an opening is reserved at the top of the second protective cover 4 and covered with the transparent plate 6. When it is necessary to adjust the parameters of the flow meter 1, the staff can pull the transparent plate 6, so that the slider 7 is forced to slide on the inner wall of the slide 8 to realize the opening, thereby facilitating the staff to touch the button set at the top of the flow meter 1.

[0025] Further, see Figure 3 and Figure 4 It can be known that the front end of the transparent plate 6 is connected to a linkage plate 10 , and a handle 11 is welded to the front of the linkage plate 10 . When in use, the setting of the handle 11 can facilitate the staff to pull out the transparent plate 6 .

[0026] Further, see Figure 4It can be seen that a support plate 12 is provided on the front of the second protective cover 4, and a rubber plate 13 is connected to the inner side of the support plate 12, and the lower side of the rubber plate 13 is arranged as an inclined structure. Since the lower side of the rubber plate 13 is arranged as an inclined structure, during the process of pulling out the transparent plate 6, its upper surface is always tightly fitted with the rubber plate 13. By utilizing the setting of the rubber plate 13, the dust retained above the transparent plate 6 can be quickly cleaned to ensure the cleanliness of the transparent plate 6.

[0027] Further, see Figure 4 and Figure 5 It can be known that the bottom end of the support plate 12 is symmetrically connected with a connecting piece 14, and the connecting piece 14 is arranged in an L-shaped structure. The interior of the connecting piece 14 is connected to the second protective cover 4 by bolts. The connecting piece 14 arranged in the L-shaped structure can facilitate the installation and disassembly of the support plate 12 and the second protective cover 4, so that the staff can promptly replace the first protective cover 3 that has reached the end of its service life.

[0028] Further, see Figure 5 It can be known that the front side of the connecting member 14 is rotatably connected with a rotating block 16, the front side of the linkage plate 10 is symmetrically distributed with limiting columns 15, and the inside of the limiting columns 15 is provided with limiting grooves adapted to the rotating blocks 16. When the transparent plate 6 is engaged with the top opening of the second protective cover 4, the rotating block 16 can be rotated to engage with the limiting grooves inside the limiting columns 15 to limit the linkage plate 10, which can effectively prevent the transparent plate 6 from moving easily during the covering process, so as to enhance the protection effect of the flow meter 1.

[0029] Further, see Figure 4 It can be known that a buffer pad is glued to the outer side of the linkage plate 10, and the buffer pad is located at the back side of the linkage plate 10. The buffer pad is made of rubber material, which is not shown in the figure. Through the setting of the buffer pad, it can effectively prevent the linkage plate 10 from directly colliding with the front of the second protective cover 4 when the transparent plate 6 is reset by the spring 9, so as to achieve the protection of the linkage plate 10.

[0030] Working principle: When the utility model is in use, the staff can first connect the installation pipe 2 and the water pipeline, and the flow meter 1 set above the installation pipe 2 can be used to measure the water volume. When the device is in use, the first protective cover 3 and the second protective cover 4 set outside the flow meter 1 can be used to surround and protect the flow meter 1. When the staff needs to adjust the working parameters of the flow meter 1, they can first manually rotate the two sets of rotating blocks 16 to move them out of the card slot inside the limit column 15 to release the restriction on the linkage plate 10, and then the staff can manually pull the linkage plate 10, so that the transparent plate 6 is subjected to force at the same time, and drives the sliders 7 connected on both sides thereof to slide along the inner wall of the slideway 8, so that the opening at the top of the second protective cover 4 can be opened, so that the staff can adjust the parameters of the flow meter 1. After the adjustment is completed, the staff can stop pulling the linkage plate 10, so that the transparent plate 6 can be reset by the elastic force of the spring 9, and snap into the opening at the top of the second protective cover 4 again to achieve the sealing of the second protective cover 4, and then the staff can rotate the rotating block 16 again, so that it snaps into the limiting groove of the limiting column 15 to achieve the limiting of the linkage plate 10. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
