[0025] See also Figure 1-5The present invention provides a technical solution: a simple sewage manhole cover that does not require on-site welding, including a filter plate 1 and a top cover 3. The first external groove 2 and the second external groove 201 are respectively sleeved on both sides of the outer periphery of the filter plate 1. The top cover 3 is installed on the top of the filter plate 1. The exhaust pipe 5 is detachably installed on the top of the top cover 3. Insert blocks 6 are integrally formed on the inner walls of both ends of the second external groove 201. A top protective cover 10 is fixedly installed in the middle of the bottom surface of the top cover 3.

[0026] An induced draft fan 11 is installed in the inner wall of the top shield 10, a drive motor 12 is fixedly installed in the middle of the bottom surface of the filter plate 1, the output end of the drive motor 12 is connected to a connecting shaft 13, and scrapers 14 are fixedly connected to the top end of the connecting shaft 13 at equal intervals around the periphery. Pulleys 16 are installed at equal intervals around the circumference of the bottom surface of the filter plate 1, and a locking block 17 is provided on one side of the outer periphery of the pulley 16;

[0027] The filter plate 1 and the top cover 3 form a manhole cover structure with a filtering function, which makes the ship sewage manhole cover simple to manufacture and low in cost, and does not require complex assembly processes such as subsequent welding. The filter plate 1 can filter sewage at the bow and stern corners of the ship through the filter holes on the top;

[0028] The manhole cover structure composed of the filter plate 1 and the top cover 3 can be slid to the sewage well mouth at the bow and stern corners of the ship through multiple sets of pulleys 16 on the bottom surface. After connecting with the sewage well mouth, the locking block 17 can be rotated so that the locking block 17 and the outer periphery of the pulley 16 are tightly embraced, and the pulley 16 is locked, so that the ship sewage well cover can be quickly installed at the sewage well mouth on the ship deck, which is convenient for later removal to maintain and clean the sewage well;

[0029] The scraper 14 is driven by the driving motor 12 to rotate in the built-in groove 9, so as to scrape the sewage impurities in the built-in groove 9, thereby preventing the sewage impurities filtered in the funnel-shaped built-in groove 9 from clogging the sieve holes on the top of the filter plate 1 and affecting normal drainage. At the same time, the scraped impurities can be collected by the first external groove 2 and the second external groove 201, thereby realizing the automatic cleaning of impurities blocking the sewage manhole cover, and the cleaned impurities can be removed by disassembling the external groove at a later stage.

[0030] The filter holes on the top of the filter plate 1 can be shielded by the top protective cover 10 on the bottom surface of the top cover 3. When the pungent odor spreads in the manhole cover, the induced draft fan 11 in the top protective cover 10 can guide the emitted odor, and the activated carbon in the exhaust pipe 5 is adsorbed and then discharged, thereby achieving the purification of the pungent odor at the sewage manhole cover of the ship, avoiding the spread of pungent odor in the well, and poor user experience.

[0031] Among them, an internal threaded hole 301 is opened through the middle of the top surface of the top cover 3, and the exhaust pipe 5 is connected to the inner wall of the internal threaded hole 301 through the outer thread at the bottom end. The inner cavity of the exhaust pipe 5 is filled with an activated carbon adsorption plate, so that the exhaust pipe 5 can purify and adsorb the gas in the wellhead when discharging it. The exhaust pipe 5 can be disassembled from the top cover 3 through the bottom end thread, which is convenient for the installation and subsequent maintenance of the exhaust pipe 5.

[0032] Among them, support plates 4 are integrally formed in the middle of the four outer sides of the top cover 3. The top cover 3 is connected to the top of the filter plate 1 through the support plates 4. The filter plate 1 and the top cover 3 on the top constitute a manhole cover structure with a filtering function, which makes the ship's sewage manhole cover simple to manufacture and low in cost, and does not require complex assembly processes such as subsequent welding.

[0033] Among them, a chassis 8 is fixedly installed in the middle of the bottom surface of the filter plate 1, and the chassis 8 is located outside the drive motor 12. The chassis 8 can protect the drive motor 12, so that when the filter holes on the top of the filter plate 1 are draining, the chassis 8 can provide waterproof barrier for the drive motor 12.

[0034] Among them, a built-in groove 9 is opened on the top of the filter plate 1, and the inner wall of the built-in groove 9 is a funnel-shaped structure. The funnel-shaped built-in groove 9 on the top of the filter plate 1 can concentrate the sewage at the bow and stern corners of the ship and introduce it to the top of the filter plate 1 for filtration.

[0035] Among them, an alarm float 7 is installed on one side of the top of the top cover 3. The bottom end float of the alarm float 7 is movable through the connecting line to the bottom of the filter plate 1. The alarm float 7 can float to the bottom of the wellhead through the bottom end float, which can monitor the sewage in the wellhead.

[0036] Among them, the inner walls at both ends of the first external tank 2 are provided with slots matching the plug blocks 6, and the second external tank 201 is inserted into the inner walls of the slots through the plug blocks 6 at both ends. The sewage impurities scraped by the scraper 14 can be collected by the first external tank 2 and the second external tank 201, thereby realizing the automatic cleaning of impurities blocking the sewage manhole cover, and the cleaned impurities can be removed later by disassembling the external tank.

[0037] Among them, the built-in groove 9 is an inverted funnel-shaped structure, the exhaust pipe 5 extends into the inner cavity of the built-in groove 9, the connecting shaft 13 movably penetrates the filter plate 1 and extends into the inner wall of the built-in groove 9, and the bottom surface of the scraper 14 is in contact with the inner wall of the built-in groove 9. The scraper 14 is driven by the driving motor 12 to rotate in the built-in groove 9, which can scrape the sewage impurities in the built-in groove 9 to avoid the sewage impurities filtered in the funnel-shaped built-in groove 9 from clogging the sieve holes on the top of the filter plate 1 and affecting normal drainage.

[0038] Among them, multiple groups of installation grooves 15 are opened on the circumference of the bottom surface of the filter plate 1, and the pulley 16 rotates with the inner wall of the installation groove 15, and the locking block 17 rotates at the top edge of the inner wall of the installation groove 15. The simple manhole cover structure of the ship can slide to the sewage wellhead at the bow and stern corners of the ship through the multiple groups of pulleys 16 on the bottom surface. After connecting with the sewage wellhead, the locking block 17 can be rotated to make the locking block 17 and the outer periphery of the pulley 16 tightly embrace each other, and then the pulley 16 is locked, so that the ship's sewage wellhead cover can be quickly installed at the sewage wellhead on the ship deck, which is convenient for later removal to carry out maintenance and cleaning of the sewage well.

[0039] Working principle: When installing the manhole cover at the bow and stern corners of the ship, first connect the filter plate 1 with the top cover 3 on the top, then slide the pulley 16 on the bottom surface of the filter plate 1 to the wellhead for connection, put the bottom float of the alarm float 7 into the wellhead, and then rotate the locking block 17 so that the locking block 17 and the outer periphery of the pulley 16 are tightly embraced, and then the pulley 16 is locked, so that the ship's sewage manhole cover can be quickly installed at the sewage manhole on the ship's deck;

[0040] Then, install the exhaust pipe 5 on the upper surface of the top cover 3 through threads, and insert the first external groove 2 and the second external groove 201 on the periphery of the filter plate 1 into position through the end plug block 6 and the slot;

[0041] By regularly starting the drive motor 12 to drive the scraper 14 to rotate in the built-in groove 9, the sewage impurities in the built-in groove 9 can be scraped off, thereby preventing the sewage impurities filtered in the funnel-shaped built-in groove 9 from clogging the sieve holes on the top of the filter plate 1 and affecting normal drainage. At the same time, the scraped impurities can be collected by the first external groove 2 and the second external groove 201, thereby realizing the automatic cleaning of impurities blocking the sewage manhole cover, and the cleaned impurities can be removed by disassembling the external groove at a later time.

[0042] When a pungent odor is emitted at the wellhead, the filter holes on the top of the filter plate 1 can be blocked by the top protective cover 10 on the bottom surface of the top cover 3. When the pungent odor spreads in the wellhead, the induced draft fan 11 in the top protective cover 10 can guide the emitted odor, and the activated carbon in the exhaust pipe 5 is adsorbed and then discharged, thereby achieving the purification of the pungent odor at the sewage wellhead cover of the ship, avoiding the spread of the pungent odor in the well and poor user experience.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
