[0035] When using the marine flowmeter, the flange 25 can be used to connect the pipeline, and then the electromagnetic flowmeter body 2 can be limited by the limit plate 5, and when it is subjected to the impact of water, the force can be absorbed.

[0036] Combination Figure 2 and Figure 5 The first protective shell 1 and the second protective shell 3 have an evenly distributed first spring 4 fixedly connected to one side thereof, a limiting plate 5 fixedly connected to one side of the first spring 4, a fixing plate 19 fixedly connected to the bottom of the first protective shell 1 and the second protective shell 3 on the opposite side thereof, two limiting holes 21 being provided on the tops of the two fixing plates 19, a second spring 20 fixedly connected to the bottom of the inner diameters of the two front and rear adjacent limiting holes 21, a sliding plate 22 fixedly connected to the tops of the two front and rear adjacent second springs 20, a pillar 23 fixedly connected to the tops of the two front and rear adjacent sliding plates 22, a third spring 24 sleeved on the surfaces of the two front and rear adjacent pillars 23, a pressing plate 18 passing through and slidably connected to the tops of the two front and rear adjacent pillars 23, and a mounting assembly provided at the left end of the second protective shell 3.

[0037] When the first protective shell 1 and the second protective shell 3 are spliced, the positioning plate 10 and the positioning groove 12 are used for positioning, and a sealing strip 11 is placed to increase the sealing performance. The sealing strip 11 is usually made of rubber, plastic or metal, which can prevent air, water or other substances from entering and keep the interior dry and safe.

[0038] Combination Figure 3 and Figure 4 The installation assembly includes a positioning plate 10, which is fixedly connected to the second protective shell 3. Two positioning grooves 12 are provided at the right end of the first protective shell 1. A sealing strip 11 is fixedly connected to the left end of the positioning plate 10. The first protective shell 1 and the second protective shell 3 are fixedly connected to the first connecting plate 6 at the bottom. Two threaded holes 9 are provided at the left ends of the two first connecting plates 6. Bolts 8 are provided at the inner diameter of the threaded holes 9. A cover 14 is provided at the top of the outer diameter of the first protective shell 1 and the second protective shell 3. Sub-buckles 16 are fixedly connected to the left and right ends of the outer diameter of the cover 14. Fixed blocks 15 are fixedly connected to one side of the first protective shell 1 and the second protective shell 3. Female buckles 17 are fixedly connected to the opposite sides of the two fixed blocks 15. The sub-buckles 16 are engaged with the female buckles 17, and the positioning grooves 12 are engaged with the positioning plate 10.

[0039] When the two first connecting plates 6 are used to fix and splice the lower parts of the first protective shell 1 and the second protective shell 3, the stabilizing plate 7 placed under the first connecting plates 6 can support the first protective shell 1 and the second protective shell 3 to increase stability.

[0040] Working principle: When the marine electromagnetic flowmeter is used, first slide the first protective shell 1 and the second protective shell 3 into the positioning groove 12 according to the positioning plate 10 for positioning, and the sealing strip 11 plays a sealing role. Then, when the two first connecting plates 6 are spliced ​​together, the bolts 8 are used to pass through the threaded holes 9 for fixing. Then, the cover 14 is clamped above the first protective shell 1 and the second protective shell 3, and then the sub-clip 16 buckles the mother clip 17 for splicing and fixing to protect the electromagnetic flowmeter body 2. It is easy to disassemble. When splicing, the force of the first spring 4 can make the two limit plates 5 limit the electromagnetic flowmeter body 2. Then, when water passes through the electromagnetic flowmeter body 2, the electromagnetic flowmeter body 2 is impacted, and the pressure plate 18 is squeezed, and then the pressure plate 18 drives the pillar 23 to squeeze downward. At the same time, the third spring 24 contracts and pushes the sliding plate 22 to move in the limiting hole 21 to squeeze the second spring 20. This is repeated to absorb the impact force, reduce damage to the electromagnetic flowmeter body 2, and improve the service life.
