All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides the following technical solutions: a secondary sedimentation tank operation protection device, comprising: the sliding rail 7 is arranged at one circle at the upper part of the inner side wall of the secondary sedimentation tank 1, and a sliding block 8 is connected to the sliding rail 7 in a sliding manner; the slide 8 is movable in the slide rail 7.

The device also comprises an extension plate 12, one end of the extension plate 12 is fixedly connected to the sliding block 8, and the other end of the extension plate 12 is provided with a protection rope 13 for surrounding an operator.

Wherein, the end of the extension plate 12 far away from the sliding block 8 extends into the overflow tank 2 in the secondary sedimentation tank 1. As shown in FIG. 1, the secondary sedimentation tank 1 is a large circle at the outermost periphery, the overflow tank 2 is positioned in the secondary sedimentation tank 1, and in FIG. 1, the overflow tank 2 is suspended in the secondary sedimentation tank 1, so that triangular overflow weirs 3 are arranged on the inner side and the outer side of the upper surface of the overflow tank 2, and overflow can be carried out from the triangular overflow weirs 3 on the inner side and the outer side into the overflow tank 2. The overflow tank 2 can be arranged at the innermost edge of the secondary sedimentation tank 1, so that water in the secondary sedimentation tank 1 overflows from the triangular overflow weir 3 at the upper inner side of the overflow tank 2, and the above construction of the secondary sedimentation tank 1 and the overflow tank 2 is all an existing structure, so that the cleaning of the overflow tank 2 and the triangular overflow weir 3 is not affected.

As shown in fig. 1, the overflow pool further comprises a guard bar 4 arranged at the tip of the triangular overflow weir 3 of the overflow pool 2 for connecting the triangular overflow weirs 3 in series.

When a cleaning person falls down in the cleaning process, the upper tip of the triangular overflow weir 3 is covered by the protective strip 4, so that the cleaning person is prevented from directly contacting with the upper tip of the triangular overflow weir 3.

The connection between the triangular overflow weir 3 and the guard bar 4 is in two ways:

the first type is that the guard bar 4 and the triangular overflow weir 3 are made of metal, the guard bar 4 is welded at the top tip of the triangular overflow weir 3, and the guard bar 4 and the triangular overflow weir 3 are made of metal which can be welded, such as stainless steel, aluminum alloy and the like.

Second, as shown in fig. 4, a sleeve 5 is sleeved on the outer wall of the protective strip 4, a triangular sleeve 6 matched with the tip of the upper part of the triangular overflow weir 3 is fixedly connected to the lower surface of the sleeve 5, the triangular sleeve 6 is hollow and is in a shape with an opening at the lower side, and the triangular sleeve 6 is sleeved at the tip of the triangular overflow weir 3 through the opening at the lower side.

When the triangular sleeve 6 is used, the triangular sleeve 6 is clamped at the tip end of the triangular overflow weir 3 from top to bottom, and as the protective strip 4 is a whole, when one of the triangular sleeves 6 has a trend of separating from the tip end of the triangular overflow weir 3, the triangular sleeve 6 is difficult to separate under traction of the surrounding protective strip 4 and the triangular sleeve 6, and the triangular sleeve 6 can be fixed by external screws in order to prevent the triangular sleeve 6 from separating from the triangular overflow weir 3, so that the triangular sleeve 6 is firmly connected with the triangular overflow weir 3.

Preferably, the sliding rail 7 is a T-shaped sliding rail or an open square pipe sliding rail.

As shown in fig. 2 and 3, when the sliding rail 7 is an open square pipe sliding rail, the sliding block 8 is arranged inside the sliding rail 7, and two sides of the sliding block 8 in the moving direction are connected with supporting rollers 11 through supporting plates 10, and the supporting rollers 11 are supported on the inner wall of the open square pipe sliding rail in a rolling manner.

When the structure is used, the sliding block 8 is in rolling connection with the inner wall of the square opening pipe sliding rail through the supporting roller 11, so that abrasion can be reduced.

As shown in fig. 2 and 3, the support plate 10 is made of spring steel and is arc-shaped, a movable friction plate 9 is arranged on a side wall of the slide block 8 opposite to the extension plate 12, and friction bars 16 corresponding to the positions of the movable friction plate 9 are arranged on one circle of the inner wall of the sliding rail of the square tube.

When the sliding block 8 does not move, under the action of the elasticity of the support plate 10, the sliding block 8 approaches to the inner wall of the sliding rail 7, so that the movable friction plate 9 is attached to the friction strip 16, in this state, the sliding block 8 and the extension plate 12 and the protection rope 13 on the sliding block are not easy to move, and when a cleaning person slides down, the protection rope 13 limits the cleaning person, so that the anti-falling protection effect is achieved. When the cleaning person moves, the protection rope 13 is pulled outwards, the extension plate 12 and the sliding block 8 are pulled outwards by the protection rope 13, the sliding block 8 presses the support plate 10, the support plate 10 is attached to the opening of the square tube sliding rail, and therefore the movable friction plate 9 and the friction strip 16 are separated.

As shown in fig. 2, one end of the protection rope 13 is fixedly connected to the extension board 12, the other end is connected to the clamping block 14, and the extension board 12 is provided with a clamping groove 15 adapted to the clamping block 14.

The clamping block 14 adopts a T-shaped clamping block, the clamping groove 15 is a T-shaped clamping groove matched with the T-shaped clamping block, and the T-shaped clamping block is connected in a plugging manner, so that the operation is convenient.

In operation, a cleaning person first drops into overflow pool 2 to surround protective rope 13 around the waist, and then inserts clamping block 14 into clamping groove 15, thereby restricting the cleaning person to the end of extension plate 12.

Based on the figure 1, when the robot moves, the waist of the cleaner pulls the extension plate 12 and the sliding block 8 to the right by force, at the moment, the support plate 10 is pressed to be flat by the movement of the sliding block 8, at the moment, the friction strip 16 is separated from the movable friction plate 9, the cleaner moves directly, the thickness of the support plate 10 is selected to avoid overlarge elasticity, and the comfort of the movement process of the cleaner is ensured. When a cleaning person stops to clean the overflow pool 2 and the triangular overflow weir 3, the waist is not forced, and the sliding block 8 is pushed under the elastic force of the support plate 10, so that the movable friction plate 9 is contacted with the friction strip 16 again.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
