Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

Referring to fig. 1-6, the utility model is a protection plate for an inspection opening of a booster pump, comprising an arc plate 2 used for sealing the inspection opening 102 and arranged outside the inspection opening 102, wherein the arc plate 2 is made of an elastic thin plate, clamping pieces 4 are symmetrically arranged at the left end and the right end of the inner side of the arc plate 2, the outer ends of the clamping pieces 4 extend out of the arc plate 2 to compress the arc plate 2, the arc plate 2 is tightened towards the middle, the two clamping pieces 4 are drawn close towards the middle, the clamping pieces 4 can extend into the inspection opening 102, the arc plate 2 is reset, and the two clamping pieces 4 are pressed against the inner wall of a supporting seat 101.

The clamping piece 4 comprises a first U-shaped rod 401 and a second U-shaped rod 402, the open ends of the first U-shaped rod 401 and the second U-shaped rod 402 are connected, the included angle is 90 degrees, the sealed end of the first U-shaped rod 401 is fixed on the arc-shaped plate 2, and the sealed end of the second U-shaped rod 402 extends out of the arc-shaped plate 2.

The middle positions of the outer sides of the upper end and the lower end of the arc-shaped plate 2 are respectively provided with an ear plate 203, and the ear plates 203 are provided with jackscrews 204 through threaded connection.

The middle positions of the left end and the right end of the outer side of the arc-shaped plate 2 are respectively provided with a fixing plate 201, and the fixing plates 201 are respectively provided with an opening 202.

Owing to when installation arc 2, need compress the both sides of arc 2, 1 size of booster pump that uses in adding the energy storage power station is great, 2 size of arc are great, the not good assurance of staff, so still including the clamping structure who sets up in opening 202, clamping structure includes basket of flowers 3 and sets up at basket of flowers 3 both ends and screw through threaded connection and revolve to different screw rods 301, the outer end of screw rod 301 all is provided with riser 302, the inboard of riser 302 is provided with cardboard 303, cardboard 303 stretches into in the opening 202.
