[0025] As shown in Figure 2 , Figure 3 , the main cover 1 is an arch shape with an opening on one side, and the fixing member 3 is arranged at the opening on the side end of the main cover 1; a plurality of through holes 5 are arranged on the upper end of the main cover 1, and a fixing plate 6 is arranged on each of the two sides of the lower end of the main cover 1; an oval fixing hole is arranged in the middle of the fixing plate 6.

[0026] In the embodiment, the fixing member 3 is a connecting bolt, and three connecting bolts are arranged on the upper end and the two side ends of the opening end of the main cover 1.

[0027] As shown in Figure 2 , Figure 4 , the secondary cover 2 is an arch shape, which comprises a first arch-shaped plate 21 and a second arch-shaped plate 22 arranged at the front end of the first arch-shaped plate 21; the U-shaped groove 4 is arranged on the side end of the first arch-shaped plate 21.

[0028] In the embodiment, the inner contour size of the secondary cover 2 is matched with the outer contour size of the main cover 1.

[0029] In the embodiment, the number of the U-shaped grooves 4 is three.

[0030] As shown in Figure 2 , the main cover 1 is installed on the pump bottom plate and connected to the bottom plate by bolts, and the closed head is installed on the pump side to cover most of the shaft coupling.

[0031] As shown in Figure 5 , the secondary cover 2 is installed on the main cover 1, and the secondary cover 2 is adjusted to the appropriate position on the motor end according to the size of the motor of different power, so that the shaft coupling is completely wrapped by the protective cover, and then the main cover 1 and the secondary cover 2 are connected by connecting bolts.

[0032] In the embodiment, the width and height of the main cover 1 and the secondary cover 2 can be adjusted as needed.

[0033] The working principle or usage procedure of this embodiment is as follows: First, the main cover 1 is installed on the pump base plate and bolted to it. The closed end is installed on the pump side, covering most of the coupling. Then, the auxiliary cover 2 is installed on the main cover 1. Adjusting the auxiliary cover 2 to a suitable position according to the size of the motor with different power, so that the coupling is completely covered by the protective cover, the main cover 1 and the auxiliary cover 2 are then connected with connecting bolts. After installation, when the pump is started, all exposed rotating parts are completely enclosed, improving on-site safety.

[0034] Example 2

[0035] like Figure 6 As shown, in this embodiment, the first component is a first protective box 7 and the second component is a second protective box 8; a first protective box 7 with an opening at one end is provided on the outside of the main cover 1, a telescopic rod 71 is provided inside the first protective box 7, and a first magnet is provided at the top of the telescopic rod 71.

[0036] The second component is a second protective box 8. A second protective box 8 with an opening at one end is provided inside the sub-cover 2. A second magnet block is provided inside the second protective box 8. The first magnet block and the second magnet block are compatible.

[0037] In this embodiment, the width and height of the main cover 1 and the secondary cover 2 can be adjusted as needed.

[0038] In this embodiment, the installation and disassembly process of the main cover 1 and the auxiliary cover 2 is greatly simplified by utilizing the protective box, telescopic rod, and magnet. During installation, the main cover 1 is simply fixed to the pump base plate with bolts, and then the auxiliary cover 2 is brought close to the main cover 1. Under the magnetic attraction of the magnet, the two can quickly align and initially connect, greatly shortening the installation time and improving the equipment assembly efficiency. When it is necessary to disassemble the protective cover for equipment inspection or maintenance, the auxiliary cover 2 can be easily removed from the main cover 1 by overcoming the attraction of the magnet, without the need for complex tools or cumbersome operations, providing great convenience for equipment maintenance.

[0039] Compared with traditional protective cover connection methods, such as using complex mechanical locks or a large number of bolts for fixing, the embodiment reduces the number of parts to be operated, and reduces the labor and time costs in the installation and disassembly process.

[0040] By mounting the main cover 1 on the pump base plate and connecting it to the base plate with bolts, and installing the closed end on the pump side, most of the coupling is covered. Then, the auxiliary cover 2 is installed on the main cover 1. The first magnet block at the movable end of the telescopic rod 71 on the main cover 1 is magnetically connected to the second magnet block on the inner side of the second protective box 8, which facilitates the disassembly and installation of the main cover 1 and the auxiliary cover 2. At the same time, the auxiliary cover 2 can be adjusted back and forth to a suitable position to press against the motor end according to the size of different power motors, so that the coupling is completely covered by the protective cover.

[0041] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
