As shown in fig. 1 and 2, the circumferential surface of the cover body 4 is provided with a viewing port 41, and the viewing port 41 is as large as possible and is transversely arranged along the circumferential axis of the cover body 4.

As shown in fig. 2 and 5, a plurality of weight-reducing grooves 31 are uniformly distributed on the circumference of the ring frame 3, namely, the ring frame 3 is in hollow arrangement and is arranged into an annular frame body, and the weight of the ring frame 3 is greatly reduced on the premise of ensuring the supporting strength. The arrangement direction of the weight-reducing grooves 31 coincides with the observation port 41. The two ends of the ring frame 3 are respectively and integrally connected with a pump connecting disc 33 and a motor connecting disc 32; a supporting seat 6 is fixed on the inner wall of the bottom end of the pump connecting disc 33, which is close to the ring frame 3, and a gap is reserved between the upper end of the supporting seat 6 and the ring frame 3, wherein the gap is reserved for the cover body 4; the cover body 4 is rotatably arranged on the outer wall of the ring frame 3.

As shown in fig. 1, the installation of the guard uses: the pump connection pad 33 is connected with the pump body 5 through the bolt assembly, and the motor connection pad 32 is connected with the driving motor 2 through the bolt assembly, and the driving motor 2 and the supporting seat 6 are fixed on the motor seat 1. In this way, the whole protection device is stably connected. The design replaces the traditional closed protective cover, but adopts the arrangement of the ring frame 3 and the cover body 4, and the weight of the protective device is further reduced on the premise of ensuring the connection strength. The circumference fretwork of ring frame 3 sets up for the constant rotation position of viewing aperture 41 through rotatory cover body 4, thereby on the viewing aperture 41 of different positions department, see through the fretwork of ring frame 3, the inside condition of direct observation shaft coupling.

The whole structure is simple, the installation is convenient, safe and reliable.

Secondly, the design of the utility model can also play a safer role. When the condition of the internal coupling needs to be observed, the cover body 4 is rotated, so that the observation port 41 and the corresponding weight-reducing groove 31 are opposite. When the condition of the internal coupling is not required to be observed, the cover body 4 is rotated, so that the observation port 41 and the weight reducing groove 31 are staggered, and at the moment, the observation port 41 is opposite to the frame body of the ring frame 3, and the observation port 41 is blocked by the ring frame 3, so that devices such as a protective net and the like can be not arranged on the observation port 41, and the safety is higher.
