[0023] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0024] As shown in Figures 1-3 , the water power station plumb coordinate instrument protection device according to the embodiment of the present application comprises a protective box 1, a slag collecting cover 2 and a cleaning assembly.

[0025] Specifically, the protective box 1 covers the outside of the plumb coordinate instrument 8, the slag collecting cover 2 covers the top of the protective box 1 and has an inner annular cavity for the plumb line of the plumb coordinate instrument 8 to pass through, and the cleaning assembly comprises a cleaning brush 3 and a driving member, the cleaning brush 3 is swingably attached to the outer surface of the slag collecting cover 2, and the driving member is installed on the protective box 1 and connected with the cleaning brush 3 to drive the cleaning brush 3 to swing.

[0026] It can be understood that, compared with the traditional slag collecting cover 2, the application is equipped with a cleaning structure. Since the slag collecting cover 2 is around the vertical line, the rust slag falling will adhere to the surface of the slag collecting cover 2. At this time, the rust slag on the surface of the slag collecting cover 2 can be cleaned by driving the cleaning brush 3 to swing, so that the rust slag is gathered and collected, and the rust slag is prevented from adhering to the slag collecting cover 2. The whole process does not need manual participation. The inspection personnel only need to regularly pour out the rust slag collected by the slag collecting cover 2.

[0027] It should be noted that, in actual application, the starting interval of the driving member can be set, so that the driving member drives the cleaning brush 3 to clean the slag collecting cover 2 at regular intervals without manual operation of the start and stop of the equipment.

[0028] The water power station vertical line coordinate instrument protection device of the embodiment of the application is provided with the slag collecting cover 2 on the protection box 1, and the slag collecting cover 2 is equipped with the cleaning brush 3 and the driving member for driving the cleaning brush 3. Therefore, the slag collecting cover 2 can block the falling rust slag, the driving member drives the cleaning brush 3 to regularly clean the rust slag on the slag collecting cover 2, so that the rust slag is gathered and collected, and the rust slag is prevented from adhering to the slag collecting cover 2. The whole process does not need manual participation. The inspection personnel only need to regularly pour out the rust slag collected by the slag collecting cover 2, which greatly saves the manual work.

[0029] In some embodiments, as shown in Figure 1 the slag collecting cover 2 is a conical member gradually expanding in the direction towards the protection box 1, and the cleaning brush 3 extends from the top to the bottom of the slag collecting cover 2 and is swingable along the circumference of the slag collecting cover 2. Therefore, the outer circumferential surface of the slag collecting cover 2 is an inclined surface. When the cleaning brush 3 sweeps the slag collecting cover 2, the rust slag can slide down along the inclined slag collecting cover 2 under the action of gravity, which is convenient for cleaning and collecting the rust slag.

[0030] In some embodiments, as shown in Figures 1-3 the driving member includes a driving motor 6, a turntable 5 with an inner hole, and a connecting rod 4. The turntable 5 and the driving motor 6 are both arranged on the top of the protection box 1 and located in the slag collecting cover 2, and the inner hole is opposite to the inner annular cavity. The turntable 5 is rotatable relative to the protection box 1, and the connecting rod 4 extending towards the inner annular cavity is arranged on the turntable 5. The top of the connecting rod 4 is connected with the cleaning brush 3, and the driving motor 6 is used to drive the turntable 5 to rotate.

[0031] It can be understood that the inner hole of the turntable 5 can be used for the vertical line to pass through. When the driving motor 6 drives the turntable 5 to rotate, the connecting rod 4 rotates with the turntable 5, so that the cleaning brush 3 connected with the top of the connecting rod 4 can move along the circumference of the slag collecting cover 2 to clean the rust slag. The driving motor 6 and the turntable 5 are both shielded inside the slag collecting cover 2. On the one hand, the driving structure can be protected by the slag collecting cover 2. On the other hand, the driving structure can be prevented from being directly exposed to the outside, so that the appearance is good in ornamental value.

[0032] In some embodiments, the base 51 is symmetrically arranged at the bottom of the rotating table 5, and the rotating table 5 is provided with a plurality of connecting rods 4 arranged at intervals along the circumference thereof, and each connecting rod 4 is connected with a cleaning brush 3. The rotating table 5 is provided with a plurality of connecting holes 52 arranged at intervals along the circumference thereof, and each connecting hole 52 is adapted to be mounted with a connecting rod 4. In other words, the cleaning brush 3 is not limited to one, and a plurality of connecting rods 4 can be connected with a plurality of cleaning brushes 3, and each cleaning brush 3 can realize the cleaning of the slag collecting cover 2, the cleaning effect is better, and the problems of missed cleaning and incomplete cleaning are less likely to occur.

[0033] In some embodiments, as shown in Figure 1 the driving motor 6 is arranged on one side in the radial direction of the rotating table 5, and the output end of the driving motor 6 is connected with a transmission screw rod, and the outer periphery of the rotating table 5 is provided with a clamping tooth engaged with the transmission screw rod, and the transmission screw rod extends along the tangent direction of the rotating table 5. Specifically, when the driving motor 6 drives the transmission screw rod to rotate, the transmission screw rod can drive the rotating table 5 to rotate by the cooperation of the thread and the clamping tooth, so as to finally drive the cleaning brush 3 to clean the slag collecting cover 2. The cooperation of the transmission screw rod and the clamping tooth can realize transmission, and the installation angle of the driving motor 6 can be eliminated. For example, in the traditional scheme, in order to drive the rotating table 5 to rotate, the driving motor 6 needs to be installed vertically and opposite to the rotating table 5, and the vertical output shaft is used to drive the rotating table 5 to rotate in the horizontal plane. However, the vertically installed motor has the problem of large longitudinal space occupation and poor assembly stability. Meanwhile, in the present application, the central position of the rotating table 5 is used for the wiring of the vertical line, and the vertically arranged driving motor 6 may interfere with the vertical line.

[0034] In some embodiments, the slag collecting cover 2 comprises a first cover body and a second cover body which are detachably connected, and the first cover body and the second cover body are symmetrical about a first axis. The rotating table 5 comprises a first table body and a second table body which are detachably connected, and the first table body and the second table body are symmetrical about the first axis. The first axis is the central axis of the inner ring cavity. That is to say, the slag collecting cover 2 and the rotating table 5 are both split structure. The purpose of this arrangement is to eliminate assembly interference. Specifically, when the slag collecting cover 2 and the rotating table 5 are installed, the structural parts are first split, and then assembled from both sides of the vertical line. In this way, the installation of the structural parts can be realized, and the normal wiring of the vertical line will not be interfered. In addition, when the slag collecting cover 2 is poured and maintained, and the rotating table 5 is maintained and replaced, the structural parts can be directly disassembled without disassembling the vertical line coordinate instrument 8, thereby reducing the operation difficulty and improving the work efficiency.

[0035] In some embodiments, the slag collecting cover 2 comprises an outer peripheral plate, a bottom plate and an outer baffle. The top of the outer peripheral plate forms an inner ring cavity. The bottom plate is annularly arranged at the bottom of the outer peripheral plate and horizontally protrudes outward. The outer baffle is annularly arranged outside the bottom plate and vertically arranged upward. The outer peripheral plate, the bottom plate and the outer baffle constitute a slag storage groove, and the cleaning brush 3 is attached to the outer peripheral plate. In this way, when the cleaning brush 3 sweeps the outer peripheral plate, the rust slag cleaned will slide along the outer peripheral plate to the slag storage groove, thereby realizing the collection of the rust slag.

[0036] Optionally, the bottom plate is provided with an openable and closable residue discharge port. Thus, when the residue in the residue storage groove reaches a certain storage amount, the inspector can open the residue discharge port to pour out the residue, and after cleaning, the residue discharge port can be closed for re-collection of the residue.

[0037] Optionally, the residue collecting cover 2 is a piece of opaque acrylic material, which can block the collected residue and maintain the aesthetic appearance.

[0038] In some embodiments, the water power station plumb coordinate instrument protection device further comprises a water collecting tank 7 installed on the ceiling of the observation room and having an open top, the water collecting tank 7 has an inner through pipe 74 for the plumb line of the plumb coordinate instrument 8 to pass through, and the bottom of the water collecting pipe is provided with a water discharge port 71 connected with a water drain pipe 73. It should be noted that in long-term use, there is a water seepage problem between the steel lining of the plumb line and the dam concrete, which seriously affects the operation of the plumb coordinate instrument 8. By installing the water collecting tank 7 on the top of the observation room, the water collecting tank 7 can collect the seepage water, and the seepage water can be discharged through the water discharge port 71 and the water drain pipe 73, which greatly optimizes the application environment of the plumb coordinate instrument 8 and prolongs its service life.

[0039] In some embodiments, as shown in Figure 3 One side of the inner through pipe 74 has a gap extending in the up-down direction, and the gap extends towards the wall side to form a through slot 72 for avoiding the plumb line. Thus, when assembling the water collecting tank 7, the plumb coordinate instrument 8 does not need to be disassembled, and the through slot 72 can be used to assemble the plumb line to avoid the plumb line, which is convenient to operate and quick to disassemble and assemble.
