Description

Technical Field

[0001] This invention relates to the field of drainage well cover technology, and more specifically, to a multifunctional sewer drainage well cover. Background Technology

[0002] In existing technologies, conventional sewer manhole covers typically employ vertical through-hole structures for their drainage holes. While this meets basic drainage needs, it presents significant drawbacks in practical use. Firstly, in sunny or dry weather conditions, lightweight debris such as leaves, plastic bags, and paper scraps can easily fall directly into the sewer through the vertical drainage holes, accumulating over time and causing blockages, thus increasing the need for dredging. Secondly, during rainfall, clumps of debris such as mud, pebbles, and branches carried by surface runoff can easily become lodged in the vertical holes as they flow across the manhole cover surface, causing localized blockages and significantly reducing drainage efficiency.

[0003] More importantly, the drainage holes of existing manhole covers are of fixed size and cannot dynamically adjust the flow area according to the intensity of rainfall or the depth of water accumulation on the road. In extreme situations such as short-term heavy rainfall or urban flooding, the drainage capacity cannot be adaptively improved, resulting in rainwater not being discharged into the pipe network in time, exacerbating road flooding and even causing traffic disruptions and public safety risks. Summary of the Invention

[0004] To overcome the shortcomings of existing manhole covers with fixed drainage holes that cannot dynamically adjust the flow area according to rainfall intensity or road surface water depth, and whose drainage capacity cannot adaptively increase in extreme situations such as short-term heavy rainfall or urban flooding, this invention provides a multifunctional sewer drainage manhole cover.

[0005] The technical solution is as follows: A multifunctional sewer drainage manhole cover includes a manhole base and a manhole cover installed on the manhole base; it also includes a receiving plate; the manhole cover is composed of a base plate, irregularly shaped shells, and a cylinder. The base plate is movably connected to the manhole base, and several irregularly shaped shells arranged in a circular array are fixedly connected to the base plate. A cylinder is fixedly connected to the inner side of all the irregularly shaped shells, and the cylinder is fixedly connected to the base plate; several drainage grooves are provided on both sides of each irregularly shaped shell; several vertical sliding grooves are provided on the cylinder; a receiving plate is slidably connected to both the irregularly shaped shells and the cylinder, and the receiving plate is slidably positioned on... The drainage channel and vertical sliding channel are located within the well base. The outer ring surface of the receiving plate is fitted to the inner wall of the well base. Several sliding rods arranged in a circular array are fixedly connected to the middle of the lower surface of the receiving plate, and all sliding rods are slidably connected to the base plate. Each sliding rod is fitted with a spring, which is located between the receiving plate and the base plate. Several nail plates are embedded on the upper surface of the receiving plate, which are staggered with all the irregular shells. The top of the nail post on each nail plate is hemispherical, and the top of the nail post on all nail plates is lower than the upper surface of the irregular shell. Sealing components for preventing water seepage are connected to the receiving plate and the base plate.

[0006] To further address the issue of water accumulation, the sealing assembly includes a sealing ring; each slide bar has a sealing ring fitted inside the base plate at its lower part; a baffle is fixed to the center of the lower surface of the receiving plate, and the baffle is slidably connected to the base plate and tightly abuts against the inner ring surface of the cylinder.

[0007] Furthermore, each irregularly shaped shell has several hemispheres on its upper surface.

[0008] Furthermore, it also includes baffles; several baffles are fixed to the outer side of the lower surface of the receiving plate, which are distributed alternately with all the irregular shells.

[0009] To prevent sewage backflow, the system further includes sliders; four straight grooves are provided on the inner side of each irregular shell; four sliders are slidably connected inside each irregular shell, and each of the four sliders is located in a straight groove; an irregular plate is fixedly connected to the four sliders of each irregular shell, and the irregular plate is in close contact with the inner side of the irregular shell.

[0010] Furthermore, the nail plate is made of metal.

[0011] Furthermore, the irregularly shaped panels are made of a plastic material with a density lower than that of water.

[0012] To further restrict the manhole cover, an extension plate is also included; an extension plate is provided on the right side of the manhole cover, and an inclined groove is provided on the extension plate; a limiting groove is provided on the inner side of the manhole seat, and the extension plate is located in the limiting groove; two V-shaped grooves are provided on the limiting groove; a limiting rod located in the inclined groove is inserted into the two V-shaped grooves.

[0013] To facilitate manual cleaning of lumpy impurities, the device further includes a round block; the round block is slidably connected inside the cylinder; a connecting frame is fixed to the upper surface of the round block; a screen is fixed to the lower side of the connecting frame, and the shape of the screen is consistent with the shape of the receiving plate. At the same time, the nails of the nail plate penetrate through the mesh of the screen; a groove is opened on the round block; a handle is fixed to the groove.

[0014] Furthermore, the screen is made of stainless steel.

[0015] The beneficial effects of the present invention: The multifunctional sewer drainage well cover obtained by the present invention, through the above design, can intercept large debris such as branches and leaves carried in the water under rainy or sunny weather conditions by means of several nail plates, preventing them from reaching the drainage channel of each irregular shell and clogging the drainage channel, thus eliminating the need for manual dredging.

[0016] The multifunctional sewer drainage well cover designed in this invention utilizes the gravity of water to automatically press the receiving plate downwards, thereby automatically adjusting the drainage volume according to the amount of rainwater.

[0017] The multifunctional sewer drainage well cover obtained by the present invention utilizes the characteristics of the shaped plastic material to push the shaped plate and slider in each shaped shell upward in the straight slide groove when sewage backflows, until the shaped plate contacts the inner top wall of the shaped shell and cooperates with the receiving plate to seal the drainage groove on each shaped shell, preventing sewage from flowing back to the ground.

[0018] The multifunctional sewer drain cover designed in this invention allows for the removal of lumpy impurities when they accumulate on the receiving plate and several nail plates. This is achieved by manually lifting a stainless steel screen from the receiving plate and nail plates, separating the accumulated lumpy impurities from them. This facilitates quick manual removal of the lumpy impurities, promptly clearing the blockage and reducing the workload of manual dredging of the multifunctional sewer drain cover.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1: A multifunctional sewer drain cover, such as Figures 1-6 As shown, it includes a manhole base 1 and a manhole cover 2; the manhole cover 2 is hinged to the manhole base 1;

[0029] It also includes a receiving plate 3, a sliding rod 4, a spring 5, a nail plate 6, and a sealing assembly; the manhole cover 2 consists of a base plate 21, irregular shells 22, and a cylinder 23. The base plate 21 is hinged to the manhole base 1. Sixteen irregular shells 22 are welded to the base plate 21 in a circular array. The inner sides of all irregular shells 22 are welded to a cylinder 23, and the cylinder 23 is welded to the base plate 21; several drainage grooves 2201 are provided on both sides of each irregular shell 22; several vertical sliding grooves 2301 are provided on the cylinder 23; the receiving plate 3 is slidably connected to the irregular shells 22 and the cylinder 23, and the receiving plate 3 is slidably disposed on the drainage grooves 2201. 1. Inside the vertical sliding groove 2301; the outer ring surface of the receiving plate 3 is in contact with the inner wall of the well base 1; four sliding rods 4 arranged in a ring array are fixedly connected to the middle of the lower surface of the receiving plate 3, and all sliding rods 4 are slidably connected to the bottom plate 21; each sliding rod 4 is fitted with a spring 5, and the spring 5 is located between the receiving plate 3 and the bottom plate 21; several nail plates 6 are embedded on the upper surface of the receiving plate 3, and the several nail plates 6 are staggered with all the irregular shells 22; the top of the nail post on each nail plate 6 is hemispherical, and the top of the nail post on all nail plates 6 is lower than the upper surface of the irregular shell 22; sealing components are connected to the receiving plate 3 and the bottom plate 21.

[0030] The sealing assembly includes a sealing ring 101 and a retaining frame 102; each slide rod 4 is fitted with a sealing ring 101 at its lower part, and the sealing ring 101 is embedded inside the base plate 21; a retaining frame 102 is fixedly connected to the middle of the lower surface of the receiving plate 3, and the retaining frame 102 is slidably connected to the base plate 21 and closely attached to the inner ring surface of the cylinder 23.

[0031] Furthermore, each irregular shell 22 has several hemispheres 2202 on its upper surface.

[0032] Furthermore, it also includes baffles 103; several baffles 103 are fixed to the outer side of the lower surface of the receiving plate 3, and the several baffles 103 are staggered with all the irregular shells 22.

[0033] The further advantage of the above is that the friction on the upper surface of the irregular shell 22 is increased by several hemispheres 2202, and the water accumulated through the drainage channel 2201 is intercepted by the baffle 103, preventing the water from flowing onto the bottom plate 21.

[0034] It also includes sliders 104 and irregular plates 105; each irregular shell 22 has four straight grooves 2203 on its inner side; four sliders 104 are slidably connected inside each irregular shell 22, and each of the four sliders 104 is located in a straight groove 2203; an irregular plate 105 is fixedly connected to the four sliders 104 of each irregular shell 22, and the irregular plate 105 is in close contact with the inner side of the irregular shell 22.

[0035] Furthermore, nail plate 6 is made of metal.

[0036] Furthermore, the irregularly shaped plate 105 is made of a plastic material with a density lower than that of water.

[0037] The further advantages of using the above are: the strength of the metal nail plate 6 can be improved, preventing the nails on the nail plate 6 from deforming after being squeezed, and the characteristics of the irregular plate 105 can be utilized to make the irregular plate 105 float up in time under the action of sewage surging.

[0038] It also includes an extension plate 106 and a limiting rod 107; the extension plate 106 is provided on the right side of the manhole cover 2, and the extension plate 106 has an inclined groove 10601; the inner side of the manhole seat 1 is provided with a limiting groove 1001, and the extension plate 106 is located in the limiting groove 1001; two V-shaped grooves 1002 are provided on the limiting groove 1001; the limiting rod 107 is inserted into the two V-shaped grooves 1002, and the limiting rod 107 is located in the inclined groove 10601.

[0039] The working steps of this embodiment are as follows:

[0040] The following directions are Figure 1 Using the perspective reference, the direction where the manhole cover number 2 is located is to the left. The following descriptions of rotation refer to perspective directions from front to back, from top to bottom, and from right to left.

[0041] After this multifunctional sewer drain cover is installed at the sewer inlet of the main urban road, the receiving plate 3, under the action of four springs 5, is pushed to the top of the vertical sliding groove 2301. The receiving plate 3 covers the lower two-thirds of each drainage groove 2201, leaving only one-third of the drainage groove 2201 for drainage. Under normal circumstances, the accumulated water will flow along the well base 1 to the receiving plate 3, and then enter the irregular shell 22 from each one-third of the drainage groove 2201, and flow downwards into the sewer. The drainage process... In this system, several nail plates 6 can intercept larger debris such as branches and leaves carried in the water, preventing them from reaching the drainage channel 2201 of each irregular shell 22 and clogging the drainage channel 2201, thus affecting the normal drainage of the drainage channel 2201. Furthermore, in sunny or dry weather conditions, lightweight debris such as leaves, plastic bags, and paper scraps cannot directly enter the sewer from the drainage channel 2201 of the irregular shell 22. This not only avoids sewer blockage but also saves the step of manual dredging.

[0042] As rainfall gradually increases, the accumulated water gathers on the receiving plate 3 inside the well base 1, completely submerging each drainage trough 2201. When one-third of the drainage troughs 2201 cannot drain the water in time, the water accumulates on the receiving plate 3, forcing the receiving plate 3 to move downwards on the irregular shell 22 and cylinder 23. The four sliding rods 4 slide downwards on the base plate 21, and the four springs 5 ​​automatically compress, gradually enlarging the outlet of each drainage trough 2201 to increase the drainage volume. At this time, as the outlet of the drainage trough 2201 expands, if the efficiency of water accumulation on the receiving plate 3 is lower than the drainage efficiency of the expanded drainage trough 2201, the amount of water accumulating on the receiving plate 3 decreases. Under the action of the four springs 5, the receiving plate 3 and sliding rods 4 will gradually rise. The size of the drain outlet of the drainage channel 2201 is gradually reduced to decrease the drainage volume, so that the efficiency of water collection and drainage is kept in balance. If the efficiency of water collection on the receiving plate 3 is greater than the drainage efficiency of the enlarged drainage channel 2201, more water will collect on the receiving plate 3, which will continue to force the receiving plate 3 and the sliding rod 4 to gradually move down. The four springs 5 ​​will also continue to compress, further enlarging the drain outlet of the drainage channel 2201 and continuously increasing the drainage volume, so that the efficiency of water collection and drainage is kept in balance, until the receiving plate 3 descends to the bottom of the vertical sliding channel 2301, and the size of the drainage channel 2201 can no longer be expanded. In this way, the gravity of the water will automatically press the receiving plate 3 down, thereby realizing the automatic adjustment of the drainage volume according to the amount of rainwater.

[0043] As the receiving plate 3 moves up and down with the sliding rod 4, the gap between each sliding rod 4 and the base plate 21 is sealed by four sealing rings 101 to prevent water from seeping into the cylinder 23. In addition, when the receiving plate 3 moves, it moves together with the baffle frame 102. The baffle frame 102 continuously seals the vertical slide groove 2301 to prevent water from entering the cylinder 23 from the vertical slide groove 2301, corroding the sliding rod 4 and the spring 5, and affecting the normal operation of the sliding rod 4 and the spring 5.

[0044] Because the accumulated water contains fine sand and gravel, and when the water is drained through the drainage channel 2201, the water will flow onto the base plate 21. Over time, the sand and gravel accumulated on the base plate 21 will gradually increase, which will prevent the support plate 3 from moving smoothly and affect the automatic drainage function of the support plate 3. Therefore, several baffles 103 are used to intercept the water passing through the drainage channel 2201 to prevent the water from flowing onto the base plate 21 and leaving the sand and gravel on the base plate 21, thus affecting the self-regulating drainage function of the support plate 3.

[0045] During heavy rain, urban sewer pipes may become blocked, causing poor drainage and potentially leading to sewage backflow through manhole covers 2 back to the ground. This could negatively impact the environment around manhole covers 2 and degrade the city's appearance. Therefore, by utilizing the properties of the plastic material of the shaped plate 105, when sewage backflows, the shaped plate 105 and slider 104 inside each shaped shell 22 are pushed upwards within the linear slide groove 2203 until the shaped plate 105 contacts the inner top wall of the shaped shell 22. This, in conjunction with the receiving plate 3, seals the drainage groove 2201 on each shaped shell 22, preventing sewage from backflowing back to the ground.

[0046] It is important to note that when the sewer is full of sewage that cannot be discharged in time, the weight of the manhole cover 2 alone is insufficient to stop the continuously surging sewage from the manhole seat 1. The sewage that cannot be discharged in time will surge upwards, pushing the manhole cover 2 to open upwards. Therefore, after the installation of this multi-functional sewer drainage manhole cover 2, the limiting rod 107 is placed in the V-shaped groove 1002, so that the limiting rod 107 is located in the inclined groove 10601 of the extension plate 106. When the manhole cover 2 is impacted and opens upwards by the continuously surging sewage, the inclined groove 10601 of the extension plate 106 will push the limiting rod 107 to the end of the V-shaped groove 1002. The V-shaped groove 1002 restricts the extension plate 106, the limiting rod 107, and the manhole cover 2, preventing sewage from flowing back to the ground. It is also important to note that the friction of each irregular shell 22 is increased by the several hemispheres 2202 set on each irregular shell 22.

[0047] Example 2: Based on Example 1, such as Figure 7As shown, it also includes a circular block 201, a connecting frame 202, a screen 203, and a handle 204; the circular block 201 is slidably connected inside the cylinder 23; the connecting frame 202 is fixedly connected to the upper surface of the circular block 201; the screen 203 is fixedly connected to the lower side of the connecting frame 202, and the shape of the screen 203 is consistent with the shape of the receiving plate 3. At the same time, the nail post of the nail plate 6 penetrates through the mesh of the screen 203; a groove 20101 is opened on the circular block 201; the handle 204 is welded into the groove 20101.

[0048] The 203 sieve is made of stainless steel.

[0049] The working principle of this embodiment is as follows:

[0050] After prolonged use, lumpy impurities accumulate on the receiving plate 3 and several nail plates 6 of this multi-functional sewer drain cover 2, reducing the efficiency of water flow. Manually cleaning these impurities is time-consuming and labor-intensive. Furthermore, the impurities accumulated on the receiving plate 3 increase its weight, affecting its ability to automatically adjust drainage volume based on rainfall. Therefore, a stainless steel screen 203 is installed on the upper surface of the receiving plate 3. During drainage, lumpy impurities carried by the water fall onto the screen 203, thus affecting the drainage efficiency of the multi-functional sewer drain cover 2. When unblocking is required, [further action is needed]. Figure 7 As shown, only manual hand gripping of handle 204 is needed to move the round block 201, connecting frame 202 and screen 203 upwards together, allowing the screen 203 to move away from the receiving plate 3 and several nail plates 6 until the round block 201 contacts the cylinder 23. The lumpy impurities accumulated on the screen 203 are also separated from the receiving plate 3 and several nail plates 6. This makes it easy for manual removal of lumpy impurities, timely unblocking of this multi-functional sewer drain cover 2, and reducing the burden of manual unblocking of this multi-functional sewer drain cover 2.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
