DETAILED IMPLEMENTATION MANNER
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 - Figure 5, an embodiment provided by the present utility model: an anti-freezing multi-functional electromagnetic flowmeter, including two flange plates 2, fixed rings 9 are fixedly connected to the outer sides of both flange plates 2, a plurality of thin shells 20 are fixedly connected to the outer sides of the fixed rings 9, a rotating ring 18 is rotatably connected inside the fixed ring 9, a plurality of pull ropes 19 are fixedly connected to the outer side of the rotating ring 18, one end of the pull rope 19 away from the rotating ring 18 is fixedly connected to a baffle 21, a plug-in block 5 is fixedly connected to one side of the baffle 21, a spring 22 is sleeved on the outer side of the pull rope 19, a screw 7 is arranged inside the flange plate 2, a nut 8 is threadedly connected to the outer side of the screw 7, a fixed block 4 is fixedly connected to the middle of the outer side of the flange plate 2, a lower fixed block 4 is fixedly connected to a pipe body 3, a connecting flange 6 is fixedly connected to the outer side of the pipe body 3, an electromagnetic flowmeter 16 is arranged on the top of the upper fixed block 4, and a protection component is arranged on the upper fixed block 4, and the protection component is used for protecting the electromagnetic flowmeter 16.
[0033] Specifically, during the operation, if disassembly and inspection are required, first, the handle 17 on the rotating ring 18 needs to be operated. Through this action, the rotating ring 18 can rotate and simultaneously pull the pull rope 19, further driving the baffle 21 to slide inside the thin shell 20. During this process, the spring 22 is compressed, and the movement of the baffle 21 causes the plug-in block 5 to move accordingly until it completely leaves the internal space of the screw 7 and the nut 8. Subsequently, a tool is used to rotate the nut 8 to separate it from the screw 7, thereby realizing the disassembly of the pipe body 3 and the electromagnetic flowmeter 16. After the disassembly is completed, if installation is required, the two flange plates 2 need to be fixedly connected through the screw 7 and the nut 8. At this stage, only the handle 17 needs to be loosened, and under the elastic recovery action of the spring 22, the baffle 21 can move, thereby driving the plug-in block 5 to re-insert into the screw 7 and the nut 8, completing the assembly process of the entire device, effectively preventing the problem that the electromagnetic flowmeter 16 is unstable due to the loosening of the screw 7 and the nut 8 during use.
[0034] Refer to Figure 1 - Figure 3 , the protection component includes a protection housing 1, the protection housing 1 is fixedly connected to the outer side of the upper fixed block 4, a rotating rod 10 is rotatably connected inside the protection housing 1, a maintenance door 15 is fixedly connected to the outer side of the rotating rod 10, a ratchet 11 is fixedly connected to the outer side of the rotating rod 10, a pawl 12 is arranged on the outer side of the ratchet 11, a fixed rod 13 is fixedly connected inside the protection housing 1, and a torsion spring 14 is sleeved on the outer side of the fixed rod 13.
[0035] Specifically, when performing maintenance or inspection on the electromagnetic flowmeter 16, first, the maintenance door 15 needs to be operated. By rotating it along the rotating rod 10 on the outside, the ratchet 11 is driven to rotate together. During this process, the pawl 12 will rotate accordingly and, when rotated to an appropriate position, provide a safe inspection environment to prevent the accidental movement of the maintenance door 15, thus interfering with normal maintenance activities. After the inspection is completed, if it is necessary to close the maintenance door 15, the pawl 12 can be rotated downward to separate it from the ratchet 11. Then, pull the maintenance door 15 to rotate on the rotating rod 10, driving the ratchet 11 to rotate until the maintenance door 15 is completely closed. At this time, release the pawl 12, and under the elastic force of the torsion spring 14, the pawl 12 will be engaged with the ratchet 11 again to ensure that the maintenance door 15 is firmly in the closed state, completing the operation of the entire maintenance process.
[0036] Refer to Figure 1 - Figure 5 The inner part of the pawl 12 is rotatably connected to the outside of the fixed rod 13. One end of the torsion spring 14 is fixedly connected to one side of the pawl 12, and the other end of the torsion spring 14 is fixedly connected to the outside of the fixed rod 13. One end of the spring 22 is fixedly connected to the outside of the fixed ring 9, and the other end of the spring 22 is fixedly connected to one side of the baffle 21. The outside of the baffle 21 is slidably connected to the inside of the thin shell 20. The outside of the insertion block 5 is slidably connected to the inside of the thin shell 20. The outside of the upper insertion block 5 is inserted into the screw 7, and the outside of the lower insertion block 5 is inserted into the nut 8. The outside of the rotating ring 18 is fixedly connected to the handle 17, and the outside of the pull rope 19 is slidably connected to the inside of the thin shell 20.
[0037] Specifically, the inner part of the pawl 12 is rotatably connected to the fixed rod 13, one end is fixedly connected to one end of the torsion spring 14, and the other end is fixedly connected to the outside of the fixed rod 13, which plays a role in controlling the opening and closing of the maintenance door 15. One end of the torsion spring 14 is fixed to one side of the pawl 12, and the other end is fixed to the outside of the fixed rod 13. By applying torque to the pawl 12, it maintains its stable state when the maintenance door 15 is closed and provides power when it is opened. One end of the spring 22 is fixed to the outside of the fixed ring 9, and the other end is fixed to one side of the baffle 21, providing a restoring force for the movement of the baffle 21. The outside of the baffle 21 is slidably connected to the inside of the thin shell 20. Through the compression and release of the spring 22, it realizes the linkage with the insertion block 5, thereby affecting the state of the screw 7 and the nut 8. The outside of the insertion block 5 is slidably connected to the inside of the thin shell 20, the upper part is inserted into the screw 7, and the lower part is inserted into the nut 8. It is the key component to realize the locking and unlocking of the screw 7 and the nut 8. The outside of the rotating ring 18 is fixedly connected to the handle 17, and its rotation drives the movement of the pull rope 19, thereby controlling the displacement of the baffle 21 and realizing the locking and unlocking of the screw 7 and the nut 8. The outside of the pull rope 19 is slidably connected to the inside of the thin shell 20 and is driven to move by the rotation of the rotating ring 18. Finally, through the displacement of the baffle 21, it affects the state of the screw 7 and the nut 8.
[0038] Working principle: When in use and disassembly inspection is required, by turning the handle 17 on the rotating ring 18, the rotating ring 18 rotates and at the same time the pull rope 19 is pulled to move, thus pulling the baffle 21 to slide inside the thin shell 20. At this time, the spring 22 is compressed. The movement of the baffle 21 drives the insertion block 5 to move until the insertion block 5 leaves the inside of the screw 7 and the nut 8. At this time, the nut 8 is rotated by a tool to disengage from the screw 7. At this time, the screw 7 and the nut 8 can be disassembled, and then the pipe body 3 and the electromagnetic flowmeter 16 can be disassembled. When installation is required, the two flange plates 2 are fixed by the screw 7 and the nut 8. At this time, the handle 17 is released. Under the action of the spring 22, the baffle 21 is pushed to move, thus driving the insertion block 5 to be re-inserted into the screw 7 and the nut 8. At this time, the installation is completed, avoiding the loosening of the screw 7 and the nut 8 during use and causing the electromagnetic flowmeter 16 to be unstable;
[0039] When the electromagnetic flowmeter 16 needs to be inspected, at this time, the maintenance door 15 is pulled to rotate outside the rotating rod 10, thus driving the ratchet 11 to rotate, so that the pawl 12 rotates, and then the torsion spring 14 is compressed. When rotated to the appropriate position, maintenance is carried out at this time to avoid the movement of the maintenance door 15 interfering with the maintenance. When the maintenance door 15 needs to be closed, at this time, the pawl 12 is rotated downward so that the pawl 12 disengages from the ratchet 11. At this time, the maintenance door 15 is pulled to rotate outside the rotating rod 10, thus driving the ratchet 11 to rotate to close the maintenance door 15. When the pawl 12 is released, under the action of the torsion spring 14, the pawl 12 is engaged with the ratchet 11 again.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
