Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and in particular to a structure for a municipal sewage well. Background Technology

[0002] Municipal drainage pipe networks are characterized by their wide coverage and dense distribution of manholes. Taking a medium-sized city as an example, its jurisdiction typically requires the maintenance of more than 100,000 sewage manholes. In traditional maintenance operations, each manhole needs to be equipped with an independent fence. These fences are mostly made of welded steel pipe frames, with each section generally weighing more than 15 kg. Although this type of fixed fence has the advantage of structural stability, it has exposed several problems in actual operation: First, transportation requires space in dedicated vehicles, and each operation requires 2-3 workers for loading and unloading, resulting in a significant increase in labor costs; Second, on-site assembly requires bolt connections or pin fixation, which seriously affects the maintenance progress in scenarios where multiple manholes need to be worked on continuously; Third, storage requires a large amount of storage space, and municipal maintenance units need to set up dedicated warehouses for storage and management, increasing equipment maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide a structure for municipal sewage wells to solve the problem of bulky and inconvenient independent fences during the maintenance of traditional sewage wells.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A municipal sewage well structure includes: a well shaft located underground; a support and a first well cover, the support being tightly installed on the well opening of the well shaft, and the first well cover being flip-mounted on the support; and a baffle, a groove being formed on one side of the first well cover, one end of the baffle being rotatably installed in the groove, the baffle being configured to be exposed when the first well cover is flipped open, and the other end of the baffle being connectable to the support so that the baffle is suspended on the well opening.

[0006] Based on the aforementioned technical means, this utility model directly integrates the baffle into the first manhole cover, achieving an integrated design of the protective equipment and the manhole cover. During maintenance, there is no need to carry, transport, or assemble additional fencing; only when the first manhole cover is flipped open does the baffle unfold and suspend itself at the manhole opening, forming a visual and physical barrier. Pedestrians or vehicles passing by can avoid the sewage manhole based on the baffle's warning effect. Simultaneously, the baffle can be stored within the first manhole cover and completely embedded in its back side, ensuring compatibility with existing manhole dimensions.

[0007] Because the baffle and the first manhole cover are integrated in this utility model, the baffle is protected by the first manhole cover when stored, avoiding collision damage during transportation; after the first manhole cover is closed, the baffle is completely sealed inside the manhole, reducing material aging caused by environmental factors such as rainwater and ultraviolet rays.

[0008] Furthermore, the baffle includes a first sub-baffle, a second sub-baffle, and a third sub-baffle. One end of the first sub-baffle is rotatably mounted on the first manhole cover, and the other end of the first sub-baffle is rotatably connected to one end of the second sub-baffle. The other end of the second sub-baffle is rotatably connected to the third sub-baffle, so that the first sub-baffle, the second sub-baffle, and the third sub-baffle can be folded together.

[0009] Based on the aforementioned technical means, the baffle is designed with a rotating connection of a first sub-baffle, a second sub-baffle, and a third sub-baffle. The baffle adopts a three-section rotating connection structure of the first, second, and third sub-baffles, supporting multi-level folding. When unfolded, the baffle can quickly descend to the wellhead by gravity or slight external force, forming a continuous physical barrier; when stored, the three sections of the baffle can be completely folded and embedded into the well cover groove, compatible with existing well barrel sizes.

[0010] Furthermore, a hook is formed on the other end of the third sub-baffle, and a hanging hole is formed on the support. The hook can be hung on the hanging hole so that the baffle can be connected to the support.

[0011] Based on the aforementioned technical means, the hook and the hanging hole achieve a rigid connection through physical interlocking, and the baffle maintains a stable suspension state through the engagement of the hook and the hanging hole. The design of the hook and the hanging hole supports one-handed operation: after the maintenance personnel flip the manhole cover, they only need to let the baffle hang down naturally, and the hook can slide into the hanging hole and lock with a slight pushing force; similarly, the maintenance personnel only need to pull the baffle in the opposite direction to unlock it, achieving quick storage.

[0012] Furthermore, the baffle also includes a first rotating shaft, which is installed on one side of the first manhole cover. One end of the first sub-baffle is rotatably connected to the first rotating shaft, so that one end of the first sub-baffle is rotatably installed on the first manhole cover.

[0013] Furthermore, the baffle also includes a second rotating shaft, and the other end of the first sub-baffle and one end of the second sub-baffle are rotatably connected via the second rotating shaft.

[0014] Furthermore, the baffle also includes a third rotating shaft, and the other end of the second sub-baffle is rotatably connected to one end of the third sub-baffle via the third rotating shaft.

[0015] Based on the aforementioned technical means, this utility model achieves multi-angle free rotation of the first sub-baffle, the second sub-baffle, and the third sub-baffle through a hierarchical connection of three independent rotating shafts. When folded, the baffles can be gradually retracted along the rotating shafts until they are completely embedded in the groove of the first manhole cover. When unfolded, they can be quickly lowered to the manhole opening through the smooth rotation of the three rotating shafts.

[0016] Furthermore, it also includes a locking element rotatably mounted on one side of the first manhole cover, the locking element being configured to lock or unlock the folded baffle during rotation.

[0017] According to the above technical means, the locking component forms a rigid connection with the baffle through rotation. In the first manhole cover closed transportation or non-maintenance state, even if it is subjected to vehicle running and vibration or human collision, the locking component can still keep the baffle tight, completely eliminating the risk of manhole exposure caused by accidental baffle opening.

[0018] Furthermore, the locking element includes a locking tongue and a base, the base being fixed to one side of the first manhole cover, and the locking tongue being rotatably mounted on the base.

[0019] According to the above-mentioned technical means, after the manhole cover is closed, it can be locked by simply rotating the locking tongue to directly contact the surface of the baffle; when opening, rotating the locking tongue in the opposite direction can release the contact, and the baffle will automatically droop and unfold due to gravity.

[0020] Furthermore, it also includes a warning strip, which is installed on the baffle and can be exposed when the baffle is unfolded.

[0021] Based on the above-mentioned technical means, a warning strip is integrated on the surface of the baffle of this utility model to further enhance the safety effect through visual warning.

[0022] Furthermore, it also includes a second manhole cover, which covers the first manhole cover and whose top surface is flush with the ground.

[0023] Based on the aforementioned technical means, the second manhole cover is a decorative manhole cover. The second manhole cover adopts a decorative layer that is completely matched with the surrounding ground material, and the top surface is seamlessly flush with the ground, completely eliminating the color difference and height difference between the manhole cover and the ground.

[0024] The second manhole cover forms a double-layer covering structure with the first manhole cover. When the second manhole cover uses lightweight materials for decorative purposes, the first manhole cover retains the cast iron or ductile iron material to ensure load-bearing capacity. This satisfies both aesthetic requirements and enhances manhole safety through the double-layer structure: even if the second manhole cover undergoes slight deformation due to an accident, the first manhole cover can still keep the manhole closed, preventing falls into the manhole.

[0025] The beneficial effects achieved by this utility model are:

[0026] This invention integrates the baffle directly into the first manhole cover, achieving a unified design of the protective equipment and the manhole cover. During maintenance, there is no need to carry, transport, or assemble additional fencing; the baffle unfolds and suspends itself over the manhole opening only when the first manhole cover is flipped open, forming a visual and physical barrier. Pedestrians or vehicles can avoid the sewage manhole based on the baffle's warning effect. Simultaneously, the baffle can be stored within the first manhole cover and completely embedded in its back side, ensuring compatibility with existing manhole dimensions. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 As shown, a municipal sewage well structure includes: a well cylinder 1 located underground; a support 2 and a first well cover 3, the support 2 being tightly installed on the well opening of the well cylinder 1, and the first well cover 3 being rotatably installed on the support 2; it also includes a baffle 4, a groove 31 formed on one side of the first well cover 3, and one end of the baffle 4 being rotatably installed in the groove 31, such as... Figure 2 As shown, the baffle 4 is configured to be exposed when the first manhole cover 3 is flipped open, and the other end of the baffle 4 can be connected to the support 2 so that the baffle 4 is suspended on the manhole.

[0045] In this embodiment, the baffle 4 is directly integrated into the first manhole cover 3, achieving an integrated design of the protective equipment and the manhole cover. During maintenance, there is no need to carry, transport, or assemble additional fencing. Only when the first manhole cover 3 is flipped open does the baffle 4 unfold and suspend itself at the manhole opening, forming a visual and physical barrier. Pedestrians or vehicles can avoid the sewage manhole based on the warning effect of the baffle 4. Simultaneously, the baffle 4 can be stored within the first manhole cover 3 and completely embedded in the back of the first manhole cover 3, ensuring compatibility with existing manhole dimensions.

[0046] Because the baffle 4 and the first manhole cover 3 are integrated in this embodiment, the baffle 4 is protected by the first manhole cover 3 when stored, avoiding collision damage during transportation; after the first manhole cover 3 is closed, the baffle 4 is completely sealed inside the manhole 1, reducing material aging caused by environmental factors such as rainwater and ultraviolet rays.

[0047] In this embodiment, the baffle 4 can be made of 6061-T6 aluminum alloy, with a single piece weight controlled within 2.3kg, which is significantly lighter than traditional steel pipe fences. The surface of the baffle 4 is anodized to improve corrosion resistance and extend service life.

[0048] like Figure 1 and Figure 2 As shown, the baffle 4 includes a first sub-baffle 41, a second sub-baffle 42, and a third sub-baffle 43. One end of the first sub-baffle 41 is rotatably mounted on the first manhole cover 3. The other end of the first sub-baffle 41 is rotatably connected to one end of the second sub-baffle 42, and the other end of the second sub-baffle 42 is rotatably connected to the third sub-baffle 43, so that the first sub-baffle 41, the second sub-baffle 42, and the third sub-baffle 43 can be folded together.

[0049] The baffle 4 is designed with a rotating connection between the first sub-baffle 41, the second sub-baffle 42, and the third sub-baffle 43. The baffle 4 adopts a three-section rotating connection structure of the first sub-baffle 41, the second sub-baffle 42, and the third sub-baffle 43, which supports multi-level folding. When unfolded, the baffle can be quickly lowered to the wellhead by gravity or slight external force to form a continuous physical barrier. When stored, the three sections of the baffle can be folded and embedded into the well cover groove 31, which is compatible with existing well barrel sizes.

[0050] like Figure 1 and Figure 2 As shown, a hook 44 is formed on the other end of the third sub-baffle 43, and a hanging hole 21 is formed on the support 2. The hook 44 can be hung on the hanging hole 21 so that the baffle 4 can be connected to the support 2.

[0051] The hook 44 and the hanging hole 21 are rigidly connected through physical engagement, and the baffle 4 can maintain a stable suspension state through the engagement of the hook 44 and the hanging hole 21. The design of the hook 44 and the hanging hole 21 supports one-handed operation: after the maintenance personnel flip the manhole cover, they only need to let the baffle 4 hang down naturally, and the hook 44 can slide into the hanging hole 21 and lock with a slight push; similarly, the maintenance personnel only need to pull the baffle 4 in the opposite direction to unlock it, so as to achieve quick storage.

[0052] In this embodiment, the hook 44 is made of high-strength engineering plastic or stainless steel, and the inner wall of the hanging hole 21 is provided with a wear-resistant bushing, such as copper alloy. The two achieve soft contact through the difference in hardness. During frequent hanging, the wear between the hook 44 and the hanging hole 21 is reduced, extending the service life. At the same time, the plastic hook 44 can avoid the jamming problem caused by the corrosion of metal parts, and the reliability is significantly improved in humid environments.

[0053] like Figure 1 and Figure 2 As shown, the baffle 4 also includes a first rotating shaft 45, which is installed on one side of the first manhole cover 3. One end of the first sub-baffle 41 is rotatably connected to the first rotating shaft 45 so that one end of the first sub-baffle 41 is rotatably installed on the first manhole cover 3.

[0054] like Figure 1 and Figure 2 As shown, the baffle 4 also includes a second rotating shaft 46, and the other end of the first sub-baffle 41 is rotatably connected to one end of the second sub-baffle 42 via the second rotating shaft 46.

[0055] like Figure 1 and Figure 2 As shown, the baffle 4 also includes a third rotating shaft 47, and the other end of the second sub-baffle 42 is rotatably connected to one end of the third sub-baffle 43 through the third rotating shaft 47.

[0056] In this embodiment, the first sub-baffle 41, the second sub-baffle 42, and the third sub-baffle 43 are connected in a hierarchical manner through three independent rotating shafts, allowing them to rotate freely at multiple angles. When folded, the baffle 4 can be gradually retracted along the rotating shafts until it is completely embedded in the groove 31 of the first manhole cover 3. When unfolded, it can be quickly lowered to the manhole opening through the smooth rotation of the three rotating shafts.

[0057] In this embodiment, each shaft surface may be integrated with a solid lubricating coating (such as a molybdenum disulfide coating) or have built-in grease grooves to reduce frictional resistance during long-term use.

[0058] Preferably, in this embodiment, each pivot can be provided with a limiting protrusion (such as a shoulder or a retaining ring) to limit the rotation angle range of each sub-baffle (such as a maximum folding angle of 180° and an unfolding angle of 270°). When the baffle 4 is in the suspension protection state, the limiting design can prevent the baffle 4 from being accidentally folded due to external force, ensuring that the physical barrier always maintains effective coverage.

[0059] like Figure 1 and Figure 2 As shown, it also includes a locking element 5, which is rotatably mounted on one side of the first manhole cover 3. The locking element 5 is configured to lock or unlock the folded baffle 4 during rotation.

[0060] The locking element 5 forms a rigid connection with the baffle 4 by rotation. When the first manhole cover 3 is closed during transportation or when it is not under maintenance, even if it is subjected to vehicle crushing or vibration or human collision, the locking element 5 can still keep the baffle tight, completely eliminating the risk of manhole exposure caused by the accidental unfolding of the baffle 4.

[0061] like Figure 1 and Figure 2 As shown, the locking member 5 includes a locking tongue 51 and a base 52. The base 52 is fixed to one side of the first manhole cover 3, and the locking tongue 51 is rotatably mounted on the base 52.

[0062] After the manhole cover is closed, it can be locked by simply rotating the locking tongue 51 to directly contact the surface of the baffle 4; when opening, rotating the locking tongue in the opposite direction will release the contact, and the baffle 4 will automatically droop and unfold due to gravity.

[0063] In this embodiment, the contact surface between the locking tongue 51 and the baffle 4 can be made of a material with a high coefficient of friction, such as a rubber coating or a silicone pad, which can increase friction to prevent slippage and avoid wear caused by direct metal contact.

[0064] like Figure 2 As shown, it also includes a warning strip 6, which is installed on the baffle 4. When the baffle 4 is unfolded, the warning strip 6 can be exposed.

[0065] In this embodiment, a warning strip 6 is integrated on the surface of the baffle 4 to further enhance the safety effect through visual warning.

[0066] In this embodiment, the warning strip 6 can be made of high-brightness reflective film (such as 3M diamond-grade reflective film) or LED light strip. When the baffle 4 is unfolded, the warning strip 6 can actively reflect the headlights or emit its own light to form a conspicuous visual barrier.

[0067] Preferably, the warning strip 6 can be laid along the entire length of the baffle 4, so that a continuous warning surface can be formed when the baffle 4 is suspended at the wellhead.

[0068] like Figure 3 As shown, it also includes a second manhole cover 7, which covers the first manhole cover 3, and the top surface of the second manhole cover 7 is flush with the ground.

[0069] The second manhole cover 7 is a decorative manhole cover. The second manhole cover 7 uses a decorative layer that is completely matched with the surrounding ground material. The top surface is seamlessly flush with the ground, completely eliminating the color difference and height difference between the manhole cover and the ground.

[0070] The second manhole cover 7 and the first manhole cover 3 form a double-layer covering structure. When the second manhole cover uses lightweight materials for decorative purposes, the first manhole cover 3 still retains the cast iron or ductile iron material to ensure load-bearing capacity. This satisfies both landscaping requirements and enhances manhole safety through the double-layer structure: even if the second manhole cover 7 undergoes slight deformation due to an accident, the first manhole cover 3 can still keep the manhole closed, preventing falls into the manhole.

[0071] In this embodiment, a receiving cavity is formed on the second manhole cover 7, which corresponds to the position of the hanging hole 21. When the second manhole cover 7 covers the first manhole cover 3, the hanging hole 21 can be located inside the second manhole cover 7.

[0072] In this preferred embodiment, an elastic buffer layer, such as a rubber pad or polyurethane foam, can be provided between the second manhole cover 7 and the first manhole cover 3. When a vehicle runs over it, the buffer layer can absorb the impact force and reduce the noise of the manhole cover.

[0073] Preferably, the second manhole cover 7 is connected to the first manhole cover 3 by a hidden lock, such as an embedded spring lock or a magnetic lock. During maintenance, it can be opened by simply touching the edge of the manhole cover with a special tool, without damaging the decorative layer or removing the surrounding ground material.

[0074] The specific maintenance process in this embodiment is as follows:

[0075] Step 1: Maintenance personnel place cone-shaped warning cones and hang warning signs within 5 meters around the wellhead. Even if the baffle 4 has integrated warning strips 6, temporary warnings still need to be added to meet the specifications.

[0076] Step 2: Insert the special triangular key into the embedded spring lock on the edge of the second manhole cover 7 to open the second manhole cover 7. Move the second manhole cover 7 to the side of the manhole opening, ensuring that the decorative layer is facing upwards and free of scratches.

[0077] Step 3: Open and rotate the first manhole cover 3 at least 90°. Gently push the tail of the locking tongue 51 to rotate it and disengage it from the surface of the baffle 4. At this time, the baffle 4 will begin to droop naturally due to gravity. The maintenance personnel should gently hold the top of the baffle 4 to prevent it from drooping rapidly and hitting the inner wall of the manhole, ensuring that the three-section first sub-baffle 41, second sub-baffle 42, and third sub-baffle 43 are unfolded step by step via the pivot. Align the hook 44 at the end of the third sub-baffle 43 with the hanging hole 21 on the support 2 and lock it. At this time, the baffle 4 is completely suspended at the manhole opening, forming a physical barrier.

[0078] Step 4: Ensure that the baffle 4 covers the wellhead, the warning strip 6 is fully exposed, the hook 44 is securely connected to the hanging hole 21, and there is no risk of shaking or falling off before proceeding with downhole maintenance work.

[0079] Step 5: After maintenance, the maintenance personnel gently pull the top of the baffle 4 by hand, causing it to rotate upwards around the axis. The three-section sub-baffle folds step by step through the rotating axis, eventually fully embedding into the groove 31 on the back side of the first manhole cover 3. Rotate the locking tongue 51 so that its head rests against the surface of the baffle 4 again. Close the first manhole cover 3, slide the second manhole cover 7 back to the manhole opening, align it with the surrounding ground material, and press it vertically down until it is flush with the ground.

[0080] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
