Description

Technical Field

[0001] This invention relates to the field of manhole cover technology, specifically to a sewer manhole cover structure and its working method. Background Technology

[0002] In modern cities, when it rains heavily, water easily accumulates on the roads. In order to drain the rainwater from the roads as quickly as possible, people often lift the manhole covers and place them on the side of the road to speed up the drainage. However, due to negligence, people forget to put the manhole covers back in their original positions after the water has drained, leaving the manhole openings that were originally covered directly exposed on the road surface. This causes pedestrians or vehicles to fall into the manholes or get stuck in them because they are not paying attention.

[0003] Currently, there are many types of composite manhole covers used in urban construction projects. During installation, the manhole cover is placed on a base. For ease of maintenance, a two-layer structure is usually used. The upper layer of the manhole cover is subjected to long-term trampling and crushing, while the lower layer serves a waterproof function. However, most traditional waterproof manhole covers are made of metal, cement concrete, or resin. These covers have poor sealing and waterproofing performance and are also inconvenient to install.

[0004] However, the existing manhole covers have several drawbacks: 1. Because roadside streetlights are often out of service at night, manhole covers are easily stolen, posing a risk of theft; 2. During rainy days, water easily accumulates on the covers, and slow drainage leads to increased water accumulation and the risk of people slipping and falling inside; 3. Due to the slow drainage, rainwater accumulates over time, corroding the manhole covers and causing them to rot, increasing the cost of replacement and the associated risks; 4. The covers are prone to rotting after being washed by rainwater, making them easy to slip off and potentially causing people to fall inside, increasing the danger; 5. The covers are heavy and prone to slipping when pulled out for inspection, making inspection inconvenient. These shortcomings fail to adequately meet people's needs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sewer manhole cover structure and its working method, which solves the problems mentioned in the background art, such as sewage easily accumulating and causing blockages, resulting in drainage difficulties and water accumulation.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a sewer manhole cover structure and its working method, comprising a connecting cover, an outer shell fixedly connected to the lower part of the connecting cover, a drainage hole provided inside the connecting cover, a control rod movably connected inside the connecting cover, a water intake port fixedly connected inside the outer shell, a support shell fixedly connected inside the outer shell, and a connecting rod movably connected inside the support shell.

[0007] The support shell includes a connecting block, the top of which extends through the interior of a fixed block. A diversion plate is fixedly connected to the top of the connecting block, and the top of the connecting block extends through the interior of a rotating plate. A slider is fixedly connected to one side of the fixed block, and a groove is provided on one side of the rotating plate. A base is fixedly connected above the diversion plate, and a first spring is fixedly connected above the base. A guide roller is fixedly connected to the top of the first spring.

[0008] Optionally, the connecting cover includes a lamp tube groove, a light-emitting lamp is movably connected inside the lamp tube groove, a glass plate is fixedly connected above the lamp tube groove, and the internal structural dimensions of the top of the lamp tube groove are consistent with the external structural dimensions of the bottom of the glass plate, and the internal structural dimensions of the top of the lamp tube groove are consistent with the external structural dimensions of the bottom of the light-emitting lamp.

[0009] Optionally, the housing includes a water pump, a motor is fixedly connected to the lower part of the water pump, a sleeve is fixedly connected to the lower part of the motor, the top of the sleeve extends through the interior of the push plate, a moving rod is fixedly connected to the lower part of the push plate, and the push plate forms a telescopic structure through the moving rod, and the internal structural dimensions of the push plate are consistent with the external structural dimensions of the sleeve.

[0010] Optionally, the connecting rod includes a fixed plate, a folding plate is fixedly connected to the top of the fixed plate, a movable sleeve is fixedly connected above the folding plate, and the movable sleeve forms a telescopic structure through the folding plate, and the movable sleeve moves up and down on the connecting rod.

[0011] Optionally, the control lever includes a pull rod, a slide rail is movably connected to the lower part of the pull rod, a telescopic rod is fixedly connected to the lower part of the pull rod, a second spring is fixedly connected to the lower part of the pull rod, a locking block is fixedly connected to the lower part of the telescopic rod, a slide rail is fixedly connected to one side of the control lever, and the pull rod forms a sliding structure through the telescopic rod, and the pull rod slides within the slide rail.

[0012] Optionally, the control rod extends through the interior of the outer casing and the support casing, and the internal structural dimensions below the moving rod are consistent with the external structural dimensions above the connecting rod.

[0013] Optionally, the sleeve is configured as a rotating structure via a motor, and the sleeve drives the support shell to rotate.

[0014] Optionally, the connecting block forms a rotating structure through a support shell, and the connecting block flips through a groove on a rotating plate.

[0015] Optionally, the guide roller is formed into an elastic structure by a first spring, and the base on the diversion plate is fixedly connected to the first spring for fixation.

[0016] Optionally, the specific steps of the working method for the sewer manhole cover structure are as follows:

[0017] Step 1: The glass plate is fixed to the top of the connecting cover and connected together. The light can be movably connected through the lamp tube groove inside the connecting cover.

[0018] Step 2: Connect the outer shell below the cover and fix it with the water pump below the outer shell. The sewage above the outer shell is transferred through the water pump and the hole. The motor below the water pump makes the sleeve rotate. The push plate outside the sleeve drives the moving rod below to move, so that the moving rod can extend and retract on the sleeve.

[0019] Step 3: The motor rotates the support shell, the support shell connects to the connecting block, the connecting block connects to the rotating plate, the outer shell of the support shell passes through the guide plate connected to the fixed block of the rotating plate, the slider causes the fixed block to drive the guide plate to move inside the slide groove, causing the guide plate to rotate, causing the first spring on the base to drive the guide roller to move, preventing blockage;

[0020] Step 4: Push the movable sleeve downwards so that the folding plate connected to the movable sleeve moves on the connecting rod below the fixed plate;

[0021] Step 5: Rotate the control lever to allow the top part to be removed. The bottom part of the control lever moves upward along the slide rail, causing the pull rod to move upward on the telescopic rod connected to the second spring.

[0022] Step Six: The connecting cover drains sewage through the drain hole, the control rod connects the control shell and the support shell, and the water inlet draws water into the water pump.

[0023] This invention provides a sewer manhole cover structure and its working method, which has the following beneficial effects:

[0024] 1. The sewer manhole cover structure has a lamp tube slot fixedly connected to the top of the cover. A light bulb is movably connected inside the lamp tube slot. There is a glass plate above the lamp tube slot, and the inside of the lamp tube slot is illuminated through the glass plate. When people steal the manhole cover at night, it can alert people and provide lighting for people at night. The lamp tube is powered by sunlight to ensure that it can provide lighting at night.

[0025] 2. The sewer manhole cover structure has a water pump located at the bottom of the outer shell. The motor below the water pump is connected to a sleeve. The holes on the outer shell allow the water pump to draw in and discharge water, thereby accelerating the water flow and preventing water from accumulating. This ensures that water does not accumulate above the manhole cover and reduces the risk of slipping on the road surface.

[0026] 3. This sewer manhole cover structure uses a motor to rotate the support shell, which is connected to a connecting block. A sliding block rotates and slides down a groove on one side of the connecting block, allowing the diversion plate connected to the fixed plate to flip. This accelerates the diversion of water, allowing water to be poured in quickly and preventing water from accumulating above the manhole cover. There are two rapid water transfer devices to prevent water from accumulating on the manhole cover and to ensure rapid water flow.

[0027] 4. This sewer manhole cover structure connects to the connecting rod below the support shell via a control rod. The outer shell that fixes the cover can be disassembled, making it easy to push the movable sleeve plate outside the connecting rod inside the support shell. This allows the movable sleeve plate to be connected to the folding plate and flattened, so that the folding plate connected to the manhole cover can be locked in place. This effectively prevents the cover from slipping off and avoids the risk of people slipping into the manhole due to the manhole cover falling off, thus ensuring the safety of the manhole cover from falling off.

[0028] 5. This sewer manhole cover structure is opened by twisting a control rod. The pull rod is connected to a second spring-connected locking block. The pull rod moves up and down through a telescopic rod inside the slide rail. The lower part of the control rod is connected to a sleeve, which causes the push plate to drive the moving rod. The moving rod can drive the connected moving sleeve plate, allowing for movable movement in two ways: moving the folding plate, which allows for complete disassembly for easy inspection, or pulling the entire cover to temporarily open it. The first spring connected to the diversion plate causes the guide roller to clear any blockages in the manhole cover holes. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Please see Figures 1 to 7 This invention provides a technical solution: a sewer manhole cover structure and its working method, including a connecting cover 1, an outer shell 2 fixedly connected to the bottom of the connecting cover 1, a drainage hole 5 provided inside the connecting cover 1, a control rod 7 movably connected inside the connecting cover 1, a water inlet 6 fixedly connected inside the outer shell 2, a support shell 3 fixedly connected inside the outer shell 2, and a connecting rod 4 movably connected inside the support shell 3.

[0041] The support shell 3 includes a connecting block 306, the top of which extends through the interior of the fixing block 305. A diverting plate 303 is fixedly connected to the top of the connecting block 306. The top of the connecting block 306 extends through the interior of the rotating plate 308. A slider 307 is fixedly connected to one side of the fixing block 305. A groove 304 is provided on one side of the rotating plate 308. A base 309 is fixedly connected above the diverting plate 303. A first spring 302 is fixedly connected above the base 309. A guide roller 301 is fixedly connected to the top of the first spring 302.

[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connecting cover 1 includes a lamp tube groove 102, with a light lamp 103 movably connected inside the lamp tube groove 102. A glass plate 101 is fixedly connected above the lamp tube groove 102, and the internal structural dimensions of the top of the lamp tube groove 102 are consistent with the external structural dimensions of the bottom of the glass plate 101, and the internal structural dimensions of the top of the lamp tube groove 102 are consistent with the external structural dimensions of the bottom of the light lamp 103. Because the dimensions of the top of the lamp tube groove 102 are consistent with the dimensions of the bottom of the glass plate 101, it is convenient for the light lamp 103 inside the lamp tube groove 102 to be moved and stored, so that the light lamp 103 inside the lamp tube groove 102 on the connecting cover 1 can be fixed during use.

[0043] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the outer casing 2 includes a water pump 201, a motor 202 is fixedly connected to the lower part of the water pump 201, a sleeve 203 is fixedly connected to the lower part of the motor 202, the top of the sleeve 203 passes through the interior of the push plate 205, a moving rod 204 is fixedly connected to the lower part of the push plate 205, and the push plate 205 forms a telescopic structure through the moving rod 204, and the internal structural dimensions of the push plate 205 are consistent with the external structural dimensions of the sleeve 203; because the push plate 205 causes the moving rod 204 to drive the connecting rod 4 to move, the push plate 205 and the moving rod 204 play a movable connection and movement role during use.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, the connecting rod 4 includes a fixed plate 403, a folding plate 402 is fixedly connected to the top of the fixed plate 403, and a movable sleeve plate 401 is fixedly connected above the folding plate 402. The movable sleeve plate 401 forms a telescopic structure through the folding plate 402, and the movable sleeve plate 401 moves up and down at the connecting rod 4. Because the movable sleeve plate 401 drives the folding plate 402 to move on the connecting rod 4, the folding plate 402 is fixed to the connecting rod 4, and the folding plate 402 is fixedly inserted into the manhole cover groove for fixation. Thus, during use, the movable sleeve plate 401 drives the folding plate 402 to move and fix.

[0045] In this embodiment, as Figure 1 and Figure 7 As shown, the control lever 7 includes a pull rod 701, a slide rail 702 movably connected to the lower part of the pull rod 701, a telescopic rod 703 fixedly connected to the lower part of the pull rod 701, a second spring 704 fixedly connected to the lower part of the pull rod 701, a locking block 705 fixedly connected to the lower part of the telescopic rod 703, and a slide rail 702 fixedly connected to one side of the control lever 7. The pull rod 701 forms a sliding structure through the telescopic rod 703, and the pull rod 701 slides within the slide rail 702. Because the control lever 7 can be twisted open, the locking block 705 connected to the second spring 704 of the pull rod 701 moves within the slide rail 702 connected to the telescopic rod 703.

[0046] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the control lever 7 passes through the interior of the outer shell 2 and the support shell 3, and the internal structural dimensions of the lower part of the moving lever 204 are consistent with the external structural dimensions of the upper part of the connecting rod 4.

[0047] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the sleeve 203 forms a rotating structure through the motor 202, and the sleeve 203 drives the support shell 3 to rotate.

[0048] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the connecting block 306 forms a rotating structure through the support shell 3, and the connecting block 306 is flipped by the slide groove 304 on the rotating plate 308.

[0049] In this embodiment, as Figure 5 As shown, the guide roller 301 forms an elastic structure through the first spring 302, and the base 309 on the diversion plate 303 is fixedly connected to the first spring 302 for fixation.

[0052] Step 2: Connect the outer shell 2 below the cover 1 and fix it through the water pump 201 below the outer shell 2. The sewage above the outer shell 2 is transferred through the water pump 201 and the hole. The motor 202 below the water pump 201 causes the sleeve 203 to rotate. The push plate 205 outside the sleeve 203 drives the moving rod 204 below to move, so that the moving rod 204 can extend and retract on the sleeve 203.

[0053] Step 3: Motor 202 rotates support shell 3. Support shell 3 is connected to connecting block 306, which in turn connects to rotating plate 308. Outer shell 2 of support shell 3 passes through the guide plate 303 connected to fixed block 305 connected to rotating plate 308. Slider 307 causes fixed block 305 to drive guide plate 303 to move inside slide groove 304. Rotation of guide plate 303 causes first spring 302 on base 309 to drive guide roller 301 to move, preventing blockage.

[0054] Step 4: Push the movable sleeve 401 downwards, so that the folding plate 402 connected to the movable sleeve 401 moves on the connecting rod 4 and is below the fixed plate 403;

[0055] Step 5: Rotate the control lever 7 to allow the top to be removed. The lower part of the control lever 7 moves upward through the slide rail 702, causing the pull rod 701 to move upward. The locking block 705 connected to the second spring 704 moves on the telescopic rod 703.

[0056] Step 6: The sewage is discharged through the drain hole 5 of the connecting cover 1, and the connecting rod 4, which connects the control shell 2 and the support shell 3, is connected by the control rod 7. The water inlet 6 draws water into the water pump 201.
