Description

Technical Field

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

[0002] Municipal building drainage structures are an important part of urban infrastructure. Their core function is to quickly and effectively collect and divert surface runoff and domestic sewage to prevent urban flooding, protect the lives and property of citizens, and ensure the normal operation of the city.

[0003] However, in actual operation, these drainage structures often become clogged with silt, leaves, garbage, and other debris, resulting in a significant decrease in their flow capacity. Since most of these structures are buried underground or covered by manhole covers or other facilities, the blockage or abnormal water levels caused by poor downstream drainage are difficult to observe directly and promptly from the outside in the early stages of the problem.

[0004] Currently, monitoring the internal condition of drainage structures mainly relies on regular manual inspections by municipal workers. This management method not only requires a significant investment of manpower and resources and has relatively low inspection efficiency, but its more critical drawback lies in its delayed response. Regular inspections cannot react in real time to sudden blockages or rapidly rising water levels during heavy rains. Often, by the time inspectors discover a problem, the localized drainage obstruction has already persisted for some time, and water accumulation has even begun. This greatly increases the risk of urban flooding and misses the optimal opportunity for preventative dredging.

[0005] Therefore, existing technologies generally lack a device that is simple in structure, reliable in operation, requires no external energy supply, can automatically monitor the water level inside the drainage structure, and can promptly issue a visual warning to the outside world when the water level reaches the warning state. Therefore, this utility model proposes a municipal building drainage structure to solve the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a municipal building drainage structure, which aims to improve the problems of existing municipal building drainage structures lacking automatic and real-time early warning capabilities for abnormal internal water levels, as well as the complex and inefficient modular installation structure.

[0007] This utility model provides a municipal building drainage structure, including a hollow shell and a preventive mechanism fixed inside the shell.

[0008] The prevention mechanism includes: rotating column one and rotating column two fixedly connected to the inner wall of the housing, a floating plate set at the bottom of the housing, a movable block that can slide up and down, a fixed block one rotatably connected around rotating column one, a rotating block rotatably connected around rotating column two, a spring, and a white tube that can be movably inserted through an opening at the top of the housing.

[0009] The assembly relationship between the components is as follows: the lower end of the moving block abuts against the upper surface of the float; one end of the fixed block rotates as the moving block moves upward; the rotating block is initially held in place by the other end of the fixed block, thus limiting its rotation; one end of the spring is connected to the rotating block, and the other end is connected to the housing, used to apply a reset pull force to the rotating block; the white tube is initially held and limited by the rotating block, floats on the float, and after being released from the holding of the rotating block by the moving block and the fixed block, it is released when the spring pulls the rotating block, and then emerges from the housing.

[0010] Preferably, the prevention mechanism further includes a limiting component, which includes a limiting post fixed inside the housing, the limiting post being disposed adjacent to the spring for limiting the position of the spring to prevent it from swinging.

[0011] Preferably, the first fixed block is lever-shaped, and the first rotating column is located in the middle of the first fixed block.

[0012] Preferably, the outer wall of the housing is also provided with a locking mechanism for connecting the two housings to each other.

[0013] Preferably, the locking mechanism includes a cylinder rotatably connected to one housing, a locking plate fixedly connected to the cylinder, and a wedge fixedly connected to another housing. The wedge has a guiding slope, and the locking plate can slide over the wedge and engage with it.

[0014] Preferably, the locking mechanism further includes a fixing plate and screws. The fixing plate is fixedly connected to the locking plate and detachably fastened to the housing by the screws, which is used to reinforce the locking state.

[0015] Preferably, the upper end of the white tube has a conspicuous marking to serve as a visual warning after it emerges from the shell.

[0016] Preferably, the end of the card plate is provided with a snap-fit ​​groove that matches the shape of the wedge block to achieve stable snap-fit.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the technical problem that existing drainage structures cannot automatically monitor high water levels and provide timely warnings by setting up a purely mechanical prevention mechanism consisting of a float plate, linkage block, rotating block and signal pipe. It achieves the technical effect of automatically triggering the signal pipe to pop out by the buoyancy of the water level and realizing passive real-time early warning. The structure is simple and reliable, and improves the predictability and efficiency of municipal drainage management.

[0018] 2. This utility model solves the technical problems of complex connection methods and low installation efficiency between existing drainage structure modules by setting a locking mechanism composed of a card plate, wedge block, and a fixing plate and screws for reinforcement. It achieves a double locking effect of quick card-locking and positioning followed by screw tightening, which significantly simplifies the installation steps, shortens the construction cycle, and ensures the long-term stability of the connection.

[0019] 3. This utility model solves the comprehensive problems of traditional drainage products, such as single function, low level of intelligence and inconvenient construction, by integrating the passive early warning mechanism and the quick locking mechanism into an integrated drainage shell. It achieves the technical effect of enabling the drainage structure to have both basic drainage function and the dual advantages of intelligent early warning and modular quick installation. The overall design is compact and has high practical value. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, referring to Figures 1 to 6 This utility model provides a municipal building drainage structure, which aims to solve the problems of existing municipal building drainage structures lacking automatic early warning capabilities for abnormal internal water levels and having complex installation structures between modules.

[0024] like Figure 1 As shown, a municipal building drainage structure includes a hollow shell 1 and a prevention mechanism 3 fixed inside the shell 1; the shell 1 provides installation space and foundation support for all internal components; like Figure 2 , Figure 3 and Figure 4 As shown, the prevention mechanism 3 includes a first rotating column 341 and a second rotating column 342. Both the first rotating column 341 and the second rotating column 342 are fixedly connected to the inner wall of the housing 1 to provide a stable rotation axis for the moving components inside the prevention mechanism 3. The prevention mechanism 3 also includes a float plate 31 disposed at the bottom of the housing 1. The float plate 31 is used to directly sense changes in the water level inside the housing 1. The prevention mechanism 3 also includes a vertically arranged movable block 32 that can slide up and down. The lower end of the movable block 32 abuts against the upper surface of the float plate 31. When the float plate 31 floats up due to the buoyancy of the water, it pushes the movable block 32 to slide upward synchronously through its upper surface. The prevention mechanism 3 also includes a fixed block 33, which is rotatably connected around the rotating column 341. One end of the fixed block 33 is driven to rotate by the upward movement of the moving block 32. The prevention mechanism 3 also includes a rotating block 35, which is rotatably connected around the rotating column 342. The rotating block 35 is held by the other end of the fixed block 33, thereby restricting its own rotation. like Figure 5 and Figure 6As shown, the prevention mechanism 3 also includes a spring 36, one end of which is connected to the rotating block 35 and the other end to the housing 1. The spring 36 is used to apply a continuous reset pulling force to the rotating block 35. The prevention mechanism 3 also includes a white tube 37, which is movably inserted through the opening at the top of the housing 1. The white tube 37 is held and limited by the rotating block 35 in the initial position. When the float 31 rises due to the rise in water level, and the rotating block 35 is released from its hold by the linkage of the moving block 32 and the fixed block 33, the rotating block 35 rotates under the pull of the spring 36, thereby releasing the hold on the white tube 37. The white tube 37 then emerges from the housing 1, forming a warning signal.

[0025] Reference Figure 3 and Figure 4 The prevention mechanism 3 includes a limiting component 34, which includes a limiting post 343 fixed inside the housing 1. The limiting post 343 is used to physically limit the position of the spring 36 to prevent it from swinging laterally during stretching or contraction.

[0026] Reference Figure 3 The overall structure of the fixed block 33 is lever-shaped. The rotating column 341 is located in the middle of the fixed block 33 as the fulcrum. When the end of the fixed block 341 driven by the moving block 32 moves upward under the push of the moving block 32, the other end of the fixed block 341 used to hold the rotating block 35 will move downward in sync, thereby accurately releasing the holding state of the rotating block 35.

[0027] Reference Figure 5 and Figure 6 The upper end of the white tube 37 has a conspicuous mark, made of bright color or reflective material, so that after the white tube 37 protrudes from the shell 1, it can be quickly identified by the inspection personnel under various lighting conditions, and play a clear visual warning role.

[0028] Reference Figure 2 A locking mechanism 2 is provided on the outer wall of a housing 1. The locking mechanism 2 includes a cylinder 21 rotatably connected to the housing 1 and a locking plate 22 fixedly connected to the cylinder 21. A wedge 23 is fixedly connected to another housing 1 that needs to be connected. The wedge 23 has a guiding slope. The locking plate 22 can slide over the wedge 23 and form a preliminary engagement with it during installation. The locking mechanism 2 also includes a fixing plate 24 and a screw 25. The fixing plate 24 is fixedly connected to the locking plate 22 and is detachably fastened to the housing 1 by the screw 25. The end of the locking plate 22 is provided with a locking groove that matches the shape of the wedge 23, so that the locking plate 22 can achieve a more stable locking engagement with the wedge 23 through the locking groove.

[0029] The implementation principle of this application embodiment is as follows: During the operation of the early warning function, when the water level of the municipal drainage system does not reach the warning line, the float 31 is in a lower position, and the moving block 32 above it is also in a lower position; at this time, under the action of its own weight, one end of the fixed block 33 remains submerged, while the other end is raised upward, holding the rotating block 35, so that the rotating block 35 cannot rotate under the tension of the spring 36, and the rotating block 35 firmly locks the white pipe 37 in the initial position inside the housing 1; when encountering heavy rain or other situations that cause the water level inside the housing 1 to drop, the system will remain in the lower position. When the water level rises sharply, the buoyancy of the float plate 31 increases and it floats upward, pushing the moving block 32 upward. The moving block 32 then pushes the fixed block 33 to rotate around the rotating column 341, causing the end that holds the rotating block 35 to move downward, thus releasing the restriction on the rotating block 35. Once released, the rotating block 35 immediately rotates around the rotating column 342 under the tension of the spring 36, and the part that holds the white tube 37 moves away, allowing the white tube 37 to emerge from the top of the shell 1, sending a clear warning signal to the outside world.

[0030] During the installation process, when it is necessary to connect the two housings 1 together, the worker only needs to align the two housings 1, and then rotate the cylinder 21 on one of the housings 1, causing the clamping plate 22 to slide towards the wedge 23 on the other housing 1; the clamping plate 22 slides along the guide slope of the wedge 23, and after passing its apex, it uses the snap-fit ​​groove on the clamping plate 22 to form a quick snap-fit ​​fixation with the wedge 23; to achieve a permanent and firm connection, the screws 25 on the fixing plate 24 are tightened, so that the fixing plate 24 is pressed against the surface of the housing 1, completing the final reinforcement.
