[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-3 An electromagnetic settling device with a protective structure in this embodiment includes a settling device body 1 and a protective cover 2, and a protective component 3 is provided inside the protective cover 2.

[0025] The top of the settling device body 1 is in contact with the inner top wall of the protective cover 2. The inner top wall of the protective cover 2 is provided with a sealing gasket. The top of the settling device body 1 is sealed by the inner top wall of the protective cover 2 to prevent impurities from entering the interior of the settling device body 1 through the top of the settling device body 1. The sealing gasket can enhance the sealing performance of the top of the settling device body 1.

[0026] Specifically, the top of the settling meter body 1 can be protected by the protective component 3 and the protective cover 2. At the same time, the protective component 3 makes the protective cover 2 suitable for settling meter bodies 1 of different specifications, and also facilitates the installation and removal of the protective cover 2.

[0027] Example 2: Please refer to Figures 1-3 Based on Embodiment 1, the protective component 3 includes a transverse groove 301 formed inside the protective cover 2. The protective cover 2 has two movable grooves 302 inside. A rotating shaft 303, with one end penetrating and extending into the transverse groove 301, is rotatably connected to the top of the protective cover 2. A knob 304 is fixedly installed on the top of the rotating shaft 303. Two rotating rods 305, each with one end penetrating and extending into the two movable grooves 302, are rotatably connected to the inner top wall of the transverse groove 301. Drive wheels 306 are fixedly installed on the outer sides of the rotating shaft 303 and the two rotating rods 305. Drive belts 307 are drively connected to the outer surfaces of the upper and lower drive wheels 306. The two rotating rods... The bottom of 305 is fixedly equipped with a driving bevel gear 308. Threaded rods 309 are rotatably connected between the left and right side walls of the inner cavity of the two movable slots 302. Driven bevel gears 310 that mesh with the driving bevel gears 308 are fixedly installed on the outer side of the two threaded rods 309. Sliding plates 311 are threadedly connected to the outer side of the two threaded rods 309. Limiting components 312 are provided at the top and bottom of the two sliding plates 311. Two push rods 313 with one end penetrating and extending into the interior of the protective cover 2 are fixedly installed on the opposite side of the two sliding plates 311. Arc-shaped fixing blocks 314 are fixedly installed on the opposite side of the two push rods 313 on the left and right sides.

[0028] The bottom of the rotating shaft 303 is rotatably connected to the inner bottom wall of the transverse groove 301 to ensure the stability of the rotation of the rotating shaft 303. When the knob 304 is turned, the knob 304 will drive the rotating shaft 303 to rotate. Under the transmission action of the transmission wheel 306 and the transmission belt 307, the rotating shaft 303 will drive the two rotating rods 305 to rotate.

[0029] In addition, the inner bottom wall of the transverse groove 301 is provided with a rotating hole that extends into the interior of the movable groove 302. The outer surfaces of the two rotating rods 305 are rotatably connected to the rotating hole. The rotating hole can ensure the stability of the rotation of the rotating rods 305 and prevent the rotating rods 305 from deviating during rotation. When the two rotating rods 305 rotate, they will drive the two active bevel gears 308 to rotate respectively. The two active bevel gears 308 will drive the two driven bevel gears 310 that mesh with them to rotate respectively. The two driven bevel gears 310 will drive the two threaded rods 309 to rotate respectively. At this time, the rotation directions of the two threaded rods 309 are opposite.

[0030] It should be noted that when the two threaded rods 309 rotate, under the action of the limiting component 312, the two sliding plates 311 cannot rotate, but can only move to the left or right under the action of the thread thrust. The outer threads of the two threaded rods 309 are opposite, ensuring that when the two threaded rods 309 rotate, the two sliding plates 311 will move to the opposite side.

[0031] In addition, the two sliding plates 311 will drive the two push rods 313 on the left and right sides to move to the opposite side respectively. The left and right side walls of the inner cavity of the protective cover 2 are provided with two sliding holes that penetrate into the movable groove 302. The outer surfaces of the two push rods 313 on the left and right sides are slidably connected to the two sliding holes on the same side respectively. The stability of the push rod 313 movement is ensured by the sliding holes. The two push rods 313 on the left and right sides will drive the two arc-shaped fixed blocks 314 to move to the opposite side respectively.

[0032] Specifically, when the knob 304 is turned, the two arc-shaped fixing blocks 314 will move to the opposite side, and the opposite side of the two arc-shaped fixing blocks 314 will abut against the left and right sides of the settling device body 1 respectively. The two arc-shaped fixing blocks 314 can limit the settling device body 1 and prevent the protective cover 2 from detaching from the settling device body 1. At the same time, when the knob 304 is turned in the opposite direction, the two arc-shaped fixing blocks 314 will move to opposite sides, so as to facilitate the removal of the protective cover 2.

[0033] Example 3: Please refer to Figure 1 and Figure 3 Based on Embodiment 1 and Embodiment 2, the limiting component 312 includes a limiting block 3121 fixedly installed on the top and bottom of the two sliding plates 311, and the inner top wall and inner bottom wall of the two movable grooves 302 are provided with limiting grooves 3122 that are slidably connected to the limiting block 3121.

[0034] Specifically, the limiting block 3121 and the limiting groove 3122 can not only prevent the sliding plate 311 from rotating, but also limit the movement trajectory of the sliding plate 311, so as to avoid the sliding plate 311 moving too much and causing the sliding plate 311 to be limited by the active bevel gear 308.

[0035] The working principle of the above embodiments is as follows:

[0036] When using an electromagnetic settling device with a protective structure, place the protective cover 2 on the outside of the settling device body 1, ensuring the inner top wall of the protective cover 2 contacts the top of the settling device body 1. Then, rotate the knob 304. The knob 304 will drive the rotating shaft 303 to rotate. Under the transmission action of the transmission wheel 306 and the transmission belt 307, the rotating shaft 303 will drive the two rotating rods 305 to rotate. The two rotating rods 305 will respectively drive the two driving bevel gears 308 to rotate. The two driving bevel gears 308 will respectively drive the two meshing driven bevel gears 310 to rotate. The bevel gear 310 will drive the two threaded rods 309 to rotate. Under the action of the threaded thrust, the two threaded rods 309 will drive the two sliding plates 311 to move to the opposite side. The two sliding plates 311 will drive the two push rods 313 on the left and right sides to move to the opposite side. The two push rods 313 on the left and right sides will drive the two arc-shaped fixing blocks 314 to move to the opposite side until the opposite sides of the two arc-shaped fixing blocks 314 abut against the left and right sides of the settling meter body 1. At the same time, according to the above principle, the protective cover 2 can be removed by rotating the knob 304 in the opposite direction.
