Description

Technical Field

[0001] This utility model relates to the field of manhole cover structure technology, and in particular to a cargo hold sewage manhole cover structure. Background Technology

[0002] Sewage wells are required in ship cargo holds to collect sewage and prevent it from coming into contact with and contaminating the cargo. For example, Chinese utility model patent application number 202222150329.9 discloses a cargo hold sewage well cover assembly for covering the sewage well opening. It includes a support ring platform installed inside the sewage well opening, and a filter base plate detachably connected to the support ring platform. A pair of connecting plates are fixedly connected to the surface of the filter base plate, and a well cover plate detachably connected to the two connecting plates is also included. The surface of the well cover plate is flush with or higher than the upper surface of the sewage well opening, and a gap is left between the outer edge of the well cover plate and the inner wall of the sewage well opening. This utility model solves the problem in the prior art where the lack of obstruction in the sewage well during cleaning of the collection box may cause cargo or other debris to fall into the sewage well.

[0003] While the aforementioned manhole cover assembly can prevent other debris from falling into the sewage well, the filter holes on the filter base plate become clogged with impurities, requiring workers to manually unclog them one by one. This cumbersome process reduces the cleaning efficiency of the filter base plate. Utility Model Content

[0004] This utility model discloses a cargo hold sewage well cover structure, which solves the problem that impurities clogging the filter holes on the filter base plate need to be manually cleared.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cargo hold sewage manhole cover structure includes a detachable manhole cover plate and a filter base plate installed inside the sewage manhole. A gap is left between the outer edge of the manhole cover plate and the inner wall of the sewage manhole. A filter frame is connected to the bottom of the filter base plate. Slide plates are slidably connected to both sides of the filter frame. A spring connected to the filter frame is fixed to the bottom of the slide plate. A set of crossbars is fixed on the slide plate. A set of unblocking rods that can be inserted into the filter holes on the filter base plate are fixed to the top of the crossbars. A pressing rod penetrating the top of the filter base plate is fixed to the bottom of the manhole cover plate. The bottom end of the pressing rod presses the top end of the slide plate downward to compress the spring, so that the top end of the unblocking rod moves from the filter holes of the filter base plate to below the filter base plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects: When sewage and garbage enter the sewage well through the gap between the outer edge of the manhole cover and the inner wall of the sewage well, the sewage flows downward through the filter holes on the filter base plate, while the garbage is blocked on the filter base plate. When it is necessary to clean the garbage and other impurities on the filter base plate, the manhole cover plate is removed from the sewage well. The squeezing rod no longer squeezes the sliding plate, and the spring returns to its original position, pushing the sliding plate upward. This causes the crossbar to move the unblocking rod upward, so that the top of the unblocking rod inserts into the filter holes of the filter base plate, pushing out the garbage and other impurities and clearing the filter holes of the filter base plate. Workers can then clean the garbage and other impurities on the top surface of the filter base plate. This utility model eliminates the need for workers to manually clear the impurities in the filter holes of the filter base plate, reducing the workload of workers and improving the cleaning efficiency of the filter base plate.

[0009] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0010] like Figure 1 and Figure 2As shown, this utility model provides a cargo hold sewage well cover structure, including a detachable well cover plate 2 and a filter base plate 3 installed inside the sewage well opening 1. A gap is left between the outer edge of the well cover plate 2 and the inner wall of the sewage well opening 1. The bottom of the filter base plate 3 is connected to a filter frame 4. Slide plates 41 are slidably connected to both sides of the filter frame 4. A spring 42 connected to the filter frame 4 is fixed at the bottom of the slide plate 41. A set of crossbars 7 are fixed on the slide plate 41. A set of unblocking rods 71 ​​that can be inserted into the filter holes on the filter base plate 3 are fixed at the top of the crossbars 7. A pressing rod 8 that penetrates the top of the filter base plate 3 is fixed at the bottom of the well cover plate 2. The bottom end of the pressing rod 8 presses the top end of the slide plate 41 downward to compress the spring 42, so that the top end of the unblocking rod 71 moves from the filter holes of the filter base plate 3 to below the filter base plate 3. The bottom of the manhole cover plate 2 is fixed with a sealing frame 21 that covers the filter frame 4. The squeezing rod 8 is located inside the sealing frame 21. A collection frame 5 is placed inside the filter frame 4, and a pull rod 51 is fixed to the top of the collection frame 5. The bottom of the spring 42 is fixed with a support strip 43 that connects to the outer wall of the filter frame 4. A folded tube 44 that covers the spring 42 is fixed between the support strip 43 and the slide plate 41. The top of the unblocking rod 71 is fixed with a ball 72, the diameter of which is the same as the diameter of the filter holes on the filter base plate 3. After sewage and garbage enter the sewage well 1, the garbage is blocked by the filter base plate 3. When it is necessary to clean the garbage on the filter base plate 3, the well cover plate 2 is removed, and the bottom end of the squeezing rod 8 separates from the top end of the slide plate 41 (there are two squeezing rods 8, which are symmetrically distributed on the left and right). A set of springs 42 is provided on the bearing strip 43, and the folding tube 44 can effectively protect the springs 42. After the springs 42 return to their original position, they push the slide plate 41 upward. The set of crossbars 7 fixed on the slide plate 41 then drives the unblocking rod 71 to move upward, so that the ball 72 enters the filter hole on the filter base plate 3, and the ball 72... The top is slightly higher than the top of the filter base plate 3, which pushes out the impurities clogging the filter holes, thus clearing the filter holes. The sphere 72 is designed to prevent impurities from accumulating on top of the sphere 72. Then, the staff uses a cleaning tool to sweep all the garbage and impurities on the filter base plate 3 into the collection frame 5. The collection frame 5 is then removed from the filter frame 4 by the pull rod 51. The sewage remaining in the collection frame 5 will not drip randomly onto the ground. The garbage in the collection frame 5 will be emptied into the designated location later. The sealing frame 21 can cover the collection frame 5 to prevent sewage from flowing into the collection frame 5 when it enters the sewage well 1.

[0011] like Figure 1 and Figure 2As shown, a fixing block 31 is embedded in the filter base plate 3, and the bottom of the sealing frame 21 contacts the top of the fixing block 31. The manhole cover plate 2 is provided with a screw 22 that is threadedly connected to the sealing frame 21, and the fixing block 31 is provided with a screw hole that matches the screw 22.
