[0060] The utility model discloses a cleaning device for a nuclear power DCS board, which includes: a cabinet body, a dust suction assembly, a swing assembly and a collection assembly. The collection assembly is arranged on the front side of the swing assembly. The swing rod drives the dust suction pipe of the dust suction assembly to swing, so that the dust suction hood also makes a swinging motion, so as to increase the dust suction range of the dust suction hood, and then facilitate the more rapid dust suction operation on the surface of the nuclear power DCS board. This not only improves the dust suction efficiency, but also makes the dust suction of the nuclear power DCS board more comprehensive. Moreover, the dust is directly sucked into the collection box, strengthening the dust suction effect, and the collection drawer is also fixed to prevent the dust from overflowing and adhering to the surface of the nuclear power DCS board.

[0061] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0062] The cleaning device for a nuclear power DCS board provided by the embodiment of the present utility model, as Figure 2 shown, includes: a cabinet body 1, a dust suction assembly 23, a movable assembly and a collection assembly 22;

[0063] The cabinet body 1 is used to load the nuclear power DCS board 5;

[0064] The dust suction assembly 23 is used to be arranged in the cabinet body 1. The dust suction part of the dust suction assembly 23 is used to suck the dust of the nuclear power DCS board 5, and the dust suction part is movable;

[0065] The movable component is arranged inside the cabinet body 1 and is used to drive the dust suction part to move, so that the dust suction part can suck the dust at different positions of the nuclear power DCS board 5;

[0066] The collection component is arranged inside the cabinet body 1 and is used to collect the dust sucked by the dust suction part.

[0067] It should be noted that, as Figure 1 shown, the cabinet body 1 described above is equivalent to the cabinet body (or housing, box body) of the cleaning device; among them, as Figure 2 shown, the nuclear power DCS board 5 can be installed inside the back panel (back plate) of the cabinet body 1; of course, after the nuclear power DCS board 5 is installed inside the back of the cabinet body 1, it can be fixed by fasteners (screws or bolt assemblies); as Figure 1 shown, an observation window 4 can be provided on the front of the cabinet body 1 to facilitate observing the cleaning condition of the nuclear power DCS board 5; the dust suction part of the dust suction component 23 is used to suck the dust on the nuclear power DCS board 5 and can move, that is, the cleaning device adopts the cleaning method of dust suction, which can avoid the dust on the nuclear power DCS board 5 from spreading inside the cabinet body 1 during cleaning; among them, the dust suction component 23 can adopt a vacuum cleaner component, and the dust suction part can be the dust suction end of the vacuum cleaner component; the movable component can be used to drive the dust suction part of the dust suction component 23 to swing or move and other activities, so that the dust suction part can suck the dust at different positions of the nuclear power DCS board 5, increasing the dust suction range of the dust suction part of the dust suction component 23 on the nuclear power DCS board 5, thus facilitating the faster cleaning of the dust on the nuclear power DCS board 5. Of course, this also improves the cleaning efficiency of the nuclear power DCS board 5 and makes the cleaning of the nuclear power DCS board 5 more comprehensive; of course, the dust sucked by the dust suction part is collected by the collection component, which is convenient for the subsequent cleaning of the dust.

[0068] That is to say, the cleaning device for the nuclear power DCS board provided by this solution is equivalent to a cleaning cabinet for the nuclear power DCS board, which is used to clean the nuclear power DCS board installed therein, that is, the dust on the nuclear power DCS board 5 is sucked by the dust suction component 23, which can avoid the situation of dust spreading inside the cabinet body 1, and the movable component drives the dust suction part of the dust suction component 23 to move, so that the dust suction part can suck the dust at more positions of the nuclear power DCS board 5, thus facilitating the faster completion of the cleaning of the dust on the nuclear power DCS board 5, that is, this method has a higher cleaning efficiency for the dust on the nuclear power DCS board 5, and this can also make the cleaning of the nuclear power DCS board 5 more comprehensive.

[0069] In this solution, as Figure 2 shown, the dust suction part of the dust suction component 23 is arranged below the nuclear power DCS board 5;

[0070] The movable component includes a swinging component 21;

[0071] The swinging component 21 is used to drive the dust suction part to swing around the first horizontal direction; wherein, the first horizontal direction is perpendicular to the nuclear power DCS board 5.

[0072] Among them, as Figure 2 shown, the nuclear power DCS board 5 can be installed vertically on the inner wall of the back of the cabinet 1 (the back panel, that is, the rear side panel), and is parallel to the back of the cabinet 1; the dust suction part of the dust suction component 23 can be arranged on the front side below the nuclear power DCS board 5. In this way, when the swinging component 21 drives the dust suction part to swing back and forth around the first horizontal direction, the dust suction part can absorb the dust on the entire front part of the nuclear power DCS board 5 as much as possible, that is, the dust suction range of the dust suction part for the nuclear power DCS board 5 reaches the maximum as much as possible, so as to facilitate cleaning the dust on the nuclear power DCS board 5 faster.

[0073] In addition, it should be noted that the first horizontal direction can be the horizontal direction along the front and back of the cabinet 1; and the stroke of the swinging component 21 driving the dust suction part to swing left and right around the first horizontal direction ensures that the dust suction range of the dust suction part covers the entire front part of the nuclear power DCS board 5 as much as possible; of course, other movable components can also be used in this solution, such as a moving component, which is used to drive the dust suction part of the dust suction component 23 to move in the first plane; wherein, the first plane can be parallel to the front part of the nuclear power DCS board 5 and is located on the front side of the front part of the nuclear power DCS board 5.

[0074] Specifically, as Figure 3 shown, the swinging component includes: a bracket 211, a rotating rod 215, a swinging rod 216 and a driving component;

[0075] As Figure 2 shown, the bracket 211 is used to be arranged below the nuclear power DCS board 5;

[0076] As Figure 3 shown, the rotating rod 215 is arranged horizontally through the bracket 211 and can rotate back and forth around the first horizontal direction;

[0077] One end of the swinging rod 216 is perpendicularly connected to the first end of the rotating rod 215, and the dust suction part is arranged at the other end of the swinging rod 216;

[0078] The driving component is used to drive the second end of the rotating rod 215 to rotate back and forth around the first horizontal direction.

[0079] Among them, as Figure 2 and Figure 3As shown in the figure, the bracket 211 can be selected as an inverted L-shaped bracket and can be arranged between the inner walls of the left and right side plates of the cabinet body 1. The dust suction component and the collection component can be arranged on the front side of the bracket 211; the rotating rod 215 can be arranged through the bracket 211 along the horizontal direction of the front and back of the cabinet body 1. The first end of the rotating rod 215 can be located on the front side of the bracket 211, and the second end can be located on the back side of the bracket 211; of course, the bracket 211 is provided with a through hole for installing the rotating rod 215; the lower end of the swinging rod 216 is vertically connected to the first end of the rotating rod 215, and the dust suction part of the dust suction component 23 is arranged at the upper end of the swinging rod 216; wherein, the lower end of the swinging rod 216 is vertically connected to the first end of the rotating rod 215 to form an L-shaped swinging rod. The vertical end of the L-shaped swinging rod is fixed with a dust suction part, and the horizontal end rotates back and forth around the first horizontal direction under the drive of the drive component. That is to say, in the swinging component, an L-shaped swinging rod is selected as the swinging part, and the horizontal part of the L-shaped swinging rod is arranged through the bracket 211, and the horizontal end of the L-shaped swinging rod is driven to rotate back and forth by the drive component. This swinging component has a simple structure and convenient swinging.

[0080] Further, the drive component includes: a connecting rod component and a rotating component;

[0081] The rotating component drives the second end of the rotating rod 215 to rotate back and forth around the first horizontal direction through the connecting rod component. Among them, the connecting rod component is equivalent to a transmission component arranged between the rotating end of the rotating component and the second end of the rotating rod 215. Through the connecting rod component, the circumferential rotation of the rotating component can be converted into the back-and-forth rotation of the rotating rod 215, and further into the back-and-forth swing of the L-shaped swinging rod. In this way, the structure of the drive component can be simple and clear.

[0082] Still further, as Figure 3 shown, the connecting rod component includes: a first connecting rod 213 and a second connecting rod 214;

[0083] The rotating component includes a worm and gear component;

[0084] In the worm and gear component, its worm wheel 212 can be rotatably arranged on the bracket 211 around the first horizontal direction, and the worm 218 is driven to rotate by the motor 217;

[0085] The first end of the first connecting rod 213 is rotatably connected to the end face of the worm wheel 212 away from the bracket 211, and the second end is rotatably connected to the first end of the second connecting rod 214; the second end of the second connecting rod 214 is rotatably connected to the second end of the rotating rod 215.

[0086] Among them, as described above, the second end of the rotating rod 215 can be located at the back side of the inverted L-shaped bracket. To facilitate driving the second end of the rotating rod 215 to rotate back and forth around the first horizontal direction, correspondingly, as Figure 3As shown, the connecting rod assembly and the rotating assembly can also be arranged at the rear side of the inverted L-shaped bracket; among them, as Figure 3 shown, the worm and gear assembly includes: a worm wheel 212, a worm 218, a support and a motor 217; the support can be arranged on the inner wall of the bottom plate of the cabinet body 1; the worm 218 can be arranged on the support around the second horizontal direction, and the first end penetrates out of the support; among them, the second horizontal direction is perpendicular to the first horizontal direction; the motor 217 can be arranged outside the support, and its output end is drivingly connected to the first end of the worm 218; the worm wheel 212 can be rotatably arranged around the first horizontal direction at the rear side of the bracket 211, and is located above the worm 218 and meshes with the worm 218; the first end of the first connecting rod 213 is rotatably connected to the rear end surface of the worm wheel 212 away from the bracket 211. In this way, first, the motor 217 drives the worm 218 to rotate, then based on the meshing of the worm 218 and the worm wheel 212 to drive the circumferential rotation of the worm wheel 212, and then through the linkage of the first connecting rod 213 and the second connecting rod 214 to drive the second end of the rotating rod 215 to rotate back and forth around the first horizontal direction, thereby realizing the left and right swing of the swing rod 216. That is to say, in the swing assembly, the worm and gear assembly is selected as the rotating assembly, and the double connecting rod assembly is selected as the transmission assembly to drive the back-and-forth rotation of the L-shaped swing rod. This structural form of the swing assembly can make the swing of the dust suction part convenient, stable and reliable.

[0087] In this solution, as Figure 2 and Figure 4 shown, the dust suction assembly 23 includes: a vacuum cleaner 231, a dust suction pipe 232 and a dust suction hood 233;

[0088] The collection assembly is connected between the vacuum cleaner 231 and the first end of the dust suction pipe 232;

[0089] The dust suction hood 233 is arranged at the second end of the dust suction pipe 232 for sucking the dust of the nuclear power DCS board 5;

[0090] The movable assembly is used to drive the dust suction hood 233 to move so that the dust suction hood 233 can suck the dust at different positions of the nuclear power DCS board 5.

[0091] Among them, as Figure 4 shown, the collection assembly at least includes a collection box 221, that is, the collection box 221 is connected between the vacuum cleaner 231 and the first end of the dust suction pipe 232; the structure of the dust suction pipe 232 can refer to Figure 4As shown, the second end of the dust suction pipe 232 is movable, that is, both the dust suction hood 233 and the second end of the dust suction pipe 232 are movable, ensuring that the movable component can drive the dust suction hood 233 to move; among them, the dust suction pipe 232 can be a flexible pipe; of course, the vacuum cleaner 231 is used to provide suction for the dust suction hood 233, and the dust suction hood 233 can be the dust suction part described above, and there is a design for isolating dust between the vacuum cleaner 231 and the collection box 221, so that the dust is collected in the collection box 221 and is prevented from being sucked into the vacuum cleaner 231. In addition, as Figure 4 shown, the dust suction component further includes a fixing block 234; as Figure 2 shown, the fixing block 234 is arranged at the upper end of the swing rod 216 and is provided with a dust suction pipe installation through hole. The second end of the dust suction pipe 232 passes through and is installed in the dust suction pipe installation through hole of the fixing block 234, and the second end face of the dust suction pipe 232 is connected to the dust suction hood 233.

[0092] Specifically, as Figure 4 shown, the collection component includes: a collection box 221 and a collection drawer 222;

[0093] The collection box 221 is connected between the vacuum cleaner 231 and the first end of the dust suction pipe 232, and an opening is provided at the lower part of one side wall thereof;

[0094] The collection drawer 222 enters and exits the collection box 221 through the opening of the collection box 221 and is used to collect the dust sucked by the dust suction part when it is inside the collection box 221. Among them, as described above, the collection component can be arranged on the front side of the swing component, that is, the collection box 221 can be arranged on the front side of the bracket 211; as Figure 2 shown, the collection box 221 can be arranged on the inner wall of the bottom plate of the cabinet 1. The left side wall of the collection box 221 can be connected to the vacuum cleaner 231, the right side wall can be connected to the first end of the dust suction pipe 232, and an opening as described above (as Figure 6 shown) can be provided at the lower part of the front side wall; among them, as Figure 2 shown, the vacuum cleaner 231 can be arranged between the inner wall of the left side plate of the cabinet 1 and the left side wall of the collection box 221; that is, the collection drawer 222 can enter and exit the collection box 221 through the opening of the front side wall of the collection box 221, which is convenient for the collection drawer 222 to enter and exit the collection box 221, and the collection drawer 222 is used to collect the dust sucked by the dust suction part when it is inside the collection box 221, which is convenient for cleaning the collected dust; of course, when the collection drawer 222 is inside the collection box 221, its accommodation space should cover as much as possible the space at the lower part of the collection box 221, and the opening of the collection box 221 also serves as the inlet and outlet of the collection drawer.

[0095] That is to say, the collection component adopts a collection box 221 and a collection drawer 222 that can be set to enter and exit the collection box 221. Dust can be collected through the collection drawer 222, and then the collection drawer 222 can be pulled out to facilitate the cleaning of dust, so that the dust in the collection box 221 can be cleaned regularly.

[0096] Furthermore, as Figure 4 shown, when the collection drawer 222 is inside the collection box 221, its outer end face is flush with the outer end face of the opening of the collection box 221;

[0097] As Figure 2 shown, the cleaning device for nuclear power DCS boards further includes a fixing component 3;

[0098] The fixing component 3 is at least arranged on the outer end face of the opening of the collection box 221 and is used to fix the outer end face of the collection drawer 222 when the collection drawer 222 is inside the collection box 221. In this case, the collection drawer 222 is fixed inside the collection box 221 to prevent the collection drawer 222 from detaching from the opening of the collection box 221, and thus prevent the dust in the collection drawer 222 from spilling out and filling the inside of the cabinet 1, and further prevent the dust from adhering to the surface of the nuclear power DCS board 5 again, so as to ensure the reliability of the cleaning of this cleaning device.

[0099] Still further, as Figure 5 shown, the fixing component 3 includes: a fixing seat 31, an insertion block 35, a pull rod 34, and a socket 36;

[0100] As Figure 6 shown, the fixing seat 31 is arranged on the outer end face of the upper edge of the opening of the collection box 221;

[0101] The insertion block 35 can be slid up and down in the fixing seat 31 and can slide down to be lower than the upper edge of the opening of the collection box 221;

[0102] The pull rod 34 is arranged on the insertion block 35 and is used to pull the insertion block 35 to slide up and down;

[0103] The socket 36 is arranged on the upper edge of the outer end face of the collection drawer 222, and a slot 361 for inserting and cooperating with the insertion block 35 is opened at the top thereof.

[0104] Among them, as Figure 6As shown in the figure, the lower part of the front side plate of the collection box 221 may be provided with the above-mentioned opening, and the opening may be a rectangular opening; the fixing seat 31 may be arranged on the outer end surface of the upper edge of the opening of the collection box 221; the insertion block 35 may be slidably arranged up and down on the fixing seat 31, and may slide downward to a position lower than the upper edge of the opening of the collection box 221, that is, at this time the insertion block 35 is in the low position, so that when the collection drawer 222 enters the collection box 221, it is convenient for the insertion block 35 to be inserted and matched with the slot 361 of the socket 36; of course, when the collection drawer 222 is about to enter the collection box 221, if the insertion block 35 is in the low position, it will interfere with the advancement of the collection drawer 222. At this time, the insertion block 35 can be pulled upward by the pull rod 34 so that the insertion block 35 is located above the upper edge of the opening of the collection box 221, so as to facilitate the collection drawer 222 to be pushed into the collection box 221. After the collection drawer 222 enters the collection box 221, the insertion block 35 is pulled downward by the pull rod 34 so that the insertion block 35 slides to the low position and is inserted and matched with the slot 361 of the socket 36, thereby fixing the outer end surface of the collection drawer 222, which can effectively prevent the collection drawer 222 from detaching from the opening of the collection box 221.

[0105] In addition, for the extraction of the collection drawer 222, the insertion block 35 can be first pulled upward by the pull rod 34 so that the insertion block 35 is disengaged from the slot 361 of the socket 36. At this time, the fixation of the outer end surface of the collection drawer 222 is released, and then the collection drawer 222 can be normally extracted, and finally the dust in the collection drawer 222 is cleaned.

[0106] That is to say, in the fixing component 3, through the insertion and cooperation of the insertion block 35 at the upper edge of the opening of the collection box 221 and the slot 361 of the socket 36 at the upper edge of the outer end surface of the collection drawer 222, when the collection drawer 222 enters the collection box 221, the outer end surface of the collection drawer 222 can be fixed or locked; of course, this method has a simple structure and is convenient for fixing or locking.

[0107] In this solution, as Figure 6 shown, the fixing component 3 further includes: a spring 32 and a slider 33;

[0108] As Figure 6 shown, the fixing seat 31 is provided with a chute 311 in the vertical direction. The chute 311 penetrates the bottom surface and the first side surface of the fixing seat 31, and the first side surface of the fixing seat 31 faces away from the outer end surface of the upper edge of the opening of the collection box 221;

[0109] The slider 33 can be slidably arranged up and down in the chute 311;

[0110] The spring 32 is connected between the top wall of the chute 311 and the top of the slider 33, and in the natural state, the slider 33 is located at the bottom of the chute 311;

[0111] The inserted block 35 is arranged at the bottom of the sliding block 33;

[0112] The pull rod 34 is arranged at the outer side of the sliding block 33 and is used for pulling the sliding block 33 to slide up and down.

[0113] Among them, as Figure 6 shown, the first side surface of the fixed seat 31 can be the front side surface of the fixed seat 31; the sliding block 33 can be arranged to slide up and down in the sliding groove 311; among them, the front side surface of the sliding block 33 can be flush with the front side surface of the fixed seat 31, and the pull rod 34 can be arranged on the front side surface of the sliding block 33; the upper end of the spring 32 is connected to the top wall of the sliding groove 311, and the lower end is connected to the top of the sliding block 33. In the natural state without compression and elongation, the sliding block 33 is located at the bottom of the sliding groove 311; that is, in this state, the bottom of the sliding block 33 can be flush with the bottom end of the sliding groove 311. In this way, the inserted block 35 arranged at the bottom of the sliding block 33 can be lower than the upper edge of the opening of the collection box 221. That is, in the natural state of the spring 32, the inserted block 35 is in the low position described above. When the inserted block 35 is inserted and matched with the slot 361 of the socket 36 in the low position, based on the constraint of the spring 32, the inserted block 35 can be prevented from sliding upward by itself, and the inserted block 35 can be inserted and matched with the slot 361 of the socket 36 to achieve a self-locking effect, so that the fixation or locking of the outer end surface of the collection drawer 222 is more reliable.

[0114] In addition, to obtain a better fixation or locking effect on the outer end surface of the collection drawer 222, as Figure 5 shown, the number of the inserted block 35, the spring 32, the sliding block 33, the sliding groove 311 and the slot 361 is two; among them, as Figure 6 shown, the two slots 361 can be respectively opened in the left part and the right part of the fixed seat 31; the sliding blocks 33 can be respectively arranged to slide up and down in the two sliding grooves 311; one spring 32 is connected between the top wall of one sliding groove 311 and the top of the corresponding sliding block 33, and the other spring 32 is connected between the top wall of the other sliding groove 311 and the top of the other corresponding sliding block 33; the two inserted blocks 35 are respectively arranged at the bottoms of the two sliding blocks 33 and are used for being inserted and matched with the two slots 361 of the socket 36 one by one, and the pull rod 34 can be respectively connected to the outer sides of the two sliding blocks 33; in this way, it is convenient to form two sets of fixing units, so that the fixation or locking of the outer end surface of the collection drawer 222 is more stable. Of course, this fixing component 3 is also equivalent to a clamping component.

[0115] In addition, it should be noted that the working principle of this cleaning device is as follows: Start the motor 217. The output end of the motor 217 drives the worm 218 to rotate, and the worm 218 drives the engaged worm wheel 212 to rotate. The rotation of the worm wheel 212 causes the first end of the first connecting rod 213 to rotate following the back (rear end face) of the worm wheel 212, thereby pulling the second connecting rod 214 to swing. Then, the swing rod 216 is driven to swing through the rotating rod 215; Start the vacuum cleaner 231. The vacuum cleaner 231 sucks the dust on the surface of the nuclear power DCS board 5 into the inside of the dust collection hood 233 through the dust suction pipe 232, causing the dust to enter the collection box 221 and then fall into the inside of the collection drawer 222. During the dust suction process, the swing rod 216 drives the dust suction pipe 232 and the dust collection hood 233 to swing; After completing the dust suction operation, pull the pull rod 34 upward to drive the slider 33 to slide upward. After the insertion block 35 disengages from the slot of the socket 36, the collection drawer 222 is pulled out, and then the dust in the collection drawer 222 is cleaned up.
