Description

Technical Field

[0001] The utility model relates to the technical field of underwater vertical shafts, in particular to a water area self-adaptive vertical shaft protection device. Background Art

[0002] Submerged shafts, especially in urban areas and industrial applications, have always been an important part of urban infrastructure and environmental management. These shafts are often used for ventilation, drainage, sewage, or as ventilation and lighting for underwater tunnels and other underwater structures. However, with the acceleration of urbanization and the impact of climate change, traditional underwater shafts are facing more and more challenges.

[0003] In many industrial cities built along the waterfront, industrial wastewater and urban runoff often lead to severe pollution of the water body. This pollution not only poses a corrosion threat to the underwater shaft, but also blocks the shaft, affecting its drainage and ventilation functions. In areas with heavy water pollution, the underwater shaft is more likely to accumulate dirt and other foreign matter, increasing the difficulty of cleaning and maintenance. In addition, since the surface ventilation shaft is directly connected to the underwater urban infrastructure, such as tunnels, water pipelines, sewage pipelines, etc., sometimes it will flow back and forth with odor and harmful gases, affecting the quality of life of urban residents. Traditional underwater shafts need to be cleaned and maintained regularly to ensure their ventilation efficiency, which is not only labor-intensive but also costly. Therefore, the shaft usually needs to be a certain height above the water surface. According to the specific function of the shaft, it is generally required to be raised 0.5m above the flood level. However, this kind of shaft that is above the water surface for a long time will visually affect the water landscape. The exposed tall shaft may interfere with the natural habitat and may even cause animal casualties (such as bird collisions). Utility Model Content

[0004] The utility model aims to provide a water area adaptive shaft protection device to address the defects of the prior art, which can change the height of the shaft as the water level changes to prevent external water from entering the shaft.

[0005] In order to solve the above technical problems, the utility model provides a water area adaptive shaft protection device, including a mobile float and a float limiter;

[0006] The floating body limiter comprises a fixed tube, which is fixedly sleeved on the outer wall of the shaft near the top, a slot is provided inside the wall of the fixed tube, the top of the slot is open, and a sealing ring is provided on the inner wall of the slot near the top;

[0007] The movable floating body includes a buoy, a light-transmitting overflow plate is arranged on the top of the buoy, a plurality of supporting rods are arranged between the buoy and the overflow plate, the two ends of the supporting rods are respectively connected to the buoy and the overflow plate, the lower end of the buoy is inserted into the slot and is slidably connected to the slot, so that the buoy can rise and fall with the rise and fall of the water level, thereby changing the height of the shaft.

[0008] The float of the utility model is inserted into the slot of the fixed cylinder so that the float can rise and fall with the rise and fall of the water level, thereby changing the height of the vertical shaft, preventing outside water and other impurities from entering the vertical shaft when the water level rises, and preventing the top of the vertical shaft from being exposed to the outside when the water level drops, thereby interfering with the natural habitat and affecting the water landscape; by arranging a sealing ring, it is possible to prevent outside water and impurities from entering the slot to affect the up and down movement of the float and cause corrosion to the inside of the slot; by arranging a light overflow plate, the lighting of the vertical shaft is guaranteed, and the light overflow plate is connected to the float by a support rod, thereby ensuring the ventilation of the vertical shaft; in addition, the movable float and the float limiter are arranged on the outside of the vertical shaft and will not occupy the internal space of the vertical shaft.

[0009] Furthermore, a first buffer magnet is fixedly disposed at the lower end of the float, and a second buffer magnet is disposed at the bottom of the slot. The second buffer magnet is arranged corresponding to the first buffer magnet, and the second buffer magnet is used to mitigate the downward impact force of the float.

[0010] The utility model provides a first buffer magnet and a second buffer magnet. When the water level drops rapidly, the second buffer magnet can slow down the descending speed of the mobile float, thereby preventing the mobile float from having a large impact on the fixed cylinder.

[0011] Furthermore, speed-limiting magnets are arranged at intervals along the height direction on the inner wall of the slot, and the speed-limiting magnets are used to limit the moving speed of the buoy during the lifting and lowering process.

[0012] The utility model provides a speed-limiting magnet. When the water level rises or falls rapidly, the speed-limiting magnet interacts with the first buffer magnet to slow down the movement speed of the float and avoid collision between the float and the fixed cylinder.

[0013] Furthermore, the speed-limiting magnets arranged on the inner wall of the slot on the side close to the shaft are staggered with the speed-limiting magnets arranged on the inner wall of the slot on the side away from the shaft.

[0014] The speed-limiting magnets on the two inner walls of the slot of the utility model are staggeredly arranged, which can ensure that the moving speed of the float is slowed down at the entire height and can also reduce the number of speed-limiting magnets used.

[0015] Furthermore, a connecting glue is provided between the inner wall of the fixing tube and the vertical shaft, and the thickness of the connecting glue is not less than 5 mm.

[0016] The utility model sets a connecting glue between the fixed tube and the shaft, and the thickness of the connecting glue is not less than 5mm. The connecting glue has a certain elasticity. On the one hand, it can play a buffering role to reduce the direct impact of the fixed tube and the shaft caused by hard contact. On the other hand, it can adapt to the expansion or contraction of the material caused by the change of ambient temperature, and effectively prevent the stress concentration of the structure caused by temperature change.

[0017] Furthermore, the fixing cylinder and the vertical shaft are fixedly connected via a fixing piece.

[0018] The utility model fixes the fixing tube by means of the fixing piece, so as to prevent the fixing tube from being offset or turned over due to the action of water flow or other external forces.

[0019] Furthermore, the light transmission area of ​​the light overflow plate is larger than the area of ​​the shaft opening, and the support rod is arranged to be inclined outward at one end away from the buoy.

[0020] The utility model can further increase the amount of light entering the shaft and expand the existing shaft opening lighting. The overflow plate can be made of transparent acrylic, which limits the weight while further improving the light transmittance.

[0021] Furthermore, the overflow plate is umbrella-shaped, a support plate is arranged at the edge of the overflow plate, the overflow plate is connected to the support rod through the support plate, a drip groove is provided on the lower surface of the support plate, and the drip groove is arranged along the edge of the support plate to prevent external water from flowing into the vertical shaft along the overflow plate and the support rod.

[0022] The utility model designs the overflow plate into an umbrella shape and provides a drip groove, so that rainwater can flow to the edge of the overflow plate and enter the water body through the drip groove, thereby preventing external water from flowing into the vertical shaft along the overflow plate and the support rod.

[0023] Furthermore, the float includes a cylinder body and a floating block, the upper end of the cylinder body is folded outward to form a folded portion, the floating block is fixed on the lower surface of the folded portion, and the distance between the drip groove and the shaft axis is greater than the distance between the edge of the folded portion and the shaft axis.

[0024] The utility model provides a folding portion and arranges the float block on the lower surface of the folding portion, which can improve the stability of the float compared to directly arranging the float block on the cylinder body; in addition, the distance between the drip groove and the axis of the shaft is greater than the distance between the edge of the folding portion and the axis of the shaft, so that water in the drip groove can directly enter the water body without dripping on the folding portion.

[0025] Furthermore, an eco-sticker board is arranged on the outer wall of the fixed tube, and the eco-sticker board includes a plurality of board units, and two adjacent board units are detachably connected by biting, and the board unit is detachably connected to the outer wall of the fixed tube.

[0026] The plate units of the utility model and the plate units and the fixing tubes are all detachably connected, which is convenient for later maintenance and repair. In addition, the modular bite structure can improve the overall mechanical strength and form a tighter connection, thereby resisting the physical impact of water flow.

[0027] Furthermore, a habitat hole is provided on the plate unit, and a connecting hole is provided between two adjacent plate units, and the connecting hole connects the two adjacent habitat holes.

[0028] The plate units of the utility model are provided with habitat holes, and the habitat holes between the plate units are connected through connecting holes, forming a complex network of pores and channels, which effectively imitates the ecological characteristics of natural water structures such as coral reefs. The irregular hole shapes and gaps of different sizes can accommodate aquatic organisms of various sizes, thereby meeting the habitat needs of different species. The connectivity between the holes not only provides a path for small aquatic organisms such as small fish and invertebrates to shuttle freely, but also helps to maintain the natural flow of water, which is crucial for the transfer of nutrients and the discharge of waste. This natural environmental dynamic is very important for maintaining ecological balance and promoting interactions between biological species.

[0029] Furthermore, a plurality of protrusions are arranged on the surface of the plate unit.

[0030] The utility model increases the roughness of the plate unit surface by arranging a plurality of protrusions on the plate unit surface, thereby providing an ideal attachment point for algae, coral seedlings and other microorganisms. These microorganisms are the basis of the food web and provide a food source for small fish and other marine life, thereby attracting more kinds of organisms to gather there.

[0031] The beneficial effects of the utility model are:

[0032] 1. The mobile float of the utility model adapts to the change of water level to protect the shaft structure; the design of the mobile float allows it to automatically rise or fall according to the change of water level. This adaptive performance makes it unnecessary to physically raise the shaft, and can effectively protect the shaft without affecting the activities and safety on the water surface, thereby reducing the potential safety hazards caused by the structure protruding from the water surface, and also reducing the water flow interference and environmental impact caused by the shaft structure.

[0033] 2. The utility model improves the light transmittance and lighting effect of the shaft; the overflow plate made of transparent acrylic material not only limits the weight, but also greatly improves the light transmittance. In addition, its unique reverse "7" shape design further expands the amount of light entering the water surface and provides better lighting for the shaft mouth area, which is very important for improving the use function and safety of the shaft. In addition, the design of the entire device also pays attention to aesthetics and environmental protection factors. The transparent overflow plate design not only provides sufficient lighting, but also maintains the openness and visual beauty of the shaft mouth area.

[0034] 4. The utility model enhances the stability and durability of the structure; the buoy adopts a "7"-shaped folding design, combined with the use of the floating body, which not only enhances the structural stability of the buoy, but also provides excellent anti-seismic and anti-impact performance. These designs make the floating body float more stably on the water surface and extend the service life of the device.

[0035] 5. The utility model is conducive to optimizing the water environment and improving ecological compatibility; the ecological patch on the outside of the floating body limiter adopts a modular bite puzzle structure, which not only enhances the flexibility of installation, but also takes ecological compatibility into consideration, and improves the diversity of biological habitats and the ecological value of the environment by imitating the natural water structure. This design helps to protect and enhance the surrounding natural ecosystem.

[0036] 6. The maintenance cost and labor intensity of this utility model are low; the modular panel unit design allows the panel units to be replaced individually when damaged or aged, without disassembling the entire structure. This greatly reduces the maintenance cost and labor intensity, and also facilitates future expansion or replacement work.

[0037] 7. The utility model can prevent water backflow and protect the internal structure; when the mobile float moves up and down, the sealing ring effectively prevents water backflow from entering the slot, protects the internal structure from water erosion, and extends the service life of the equipment.

[0038] 8. The utility model improves the buffering effect of physical impact; by configuring magnets at the bottom and sides of the float limiter, a magnetic buffer zone is formed, which not only slows down the movement speed of the float and avoids impact damage caused by excessive movement speed, but also increases the magnetic attraction or repulsion between the two, achieving more effective impact absorption and shock absorption effects.

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] like Figure 1 As shown, this embodiment discloses an adaptive shaft protection device for water areas, including a mobile float 1 and a float limiter 2, wherein the float limiter 2 is fixedly sleeved on the outer wall of the shaft 3, and the mobile float 1 is inserted on the float limiter 2, and the mobile float 1 can rise and fall with the rise and fall of the water level.

[0051] like Figure 4 As shown, the mobile floating body 1 includes a buoy 12 , a light overflow plate 14 , and a support rod 16 .

[0052] The float 12 is a square cylindrical structure. The top of the float 12 is folded outward to form a folded portion 13. The folded portion 13 is arranged perpendicular to the float 12, so that the interface of the float 12 presents two symmetrical "7"-shaped structures. The lower surface of the folded portion 13 is fixedly provided with a float block 18. The float block 18 can be a rectangular structure with multiple circles arranged around the outside of the float 12. The float block 18 can also be set as an overall U-shaped structure to make the float 12 more stable. In this embodiment, the float block 18 is detachably connected to the float 12, and a plurality of tiny concave-convex particles are arranged on the surface of the float block 18, which not only significantly enhances the anti-slip performance, but also improves the contact tension between the float block 18 and the water surface, ensuring higher stability and durability. The interior of the float block 18 is filled with high-strength polystyrene foam with a density between 18 and 30 kg / m 3 The high-strength polystyrene foam is light and has high toughness, providing anti-vibration and impact resistance, and is easy to carry, install and dismantle.

[0053] A plurality of first buffer magnets 11 are disposed at the bottom of the float 12 .

[0054] The overflow plate 14 is arranged directly above the buoy 12. Figure 5As shown, the light overflow plate 14 is umbrella-shaped. A support plate 15 is fixedly arranged at the edge of the light overflow plate 14. The support plate 15 is square and has an opening in the middle. In this embodiment, the light-transmitting area of the light overflow plate 14 is larger than the area of the wellhead of the vertical shaft 3. The light overflow plate 14 is made of transparent acrylic, which limits the weight and further improves the light transmittance.

[0055] The support rod 16 is arranged between the support plate 15 and the folding part 13. The support rod 16 is arc-shaped. The lower end of the support rod 16 is fixedly connected to the folding part 13. The upper end of the support rod 16 extends obliquely outwards and is fixedly connected to the support plate 15, thereby fixing the light overflow plate 14 on the floating barrel 12. The support rod 16 and the support plate 15 form a structure similar to an inverted "7" shape. A water dripping groove 17 is opened on the lower surface of the support plate 15. The water dripping groove 17 is arranged in a circle along the edge of the support plate 15. The distance between the water dripping groove 17 and the axis of the vertical shaft 3 is greater than the distance between the edge of the folding part 13 and the axis of the vertical shaft 3. It can be understood that rainwater flows through the umbrella-shaped light overflow plate 14 to the support plate 15 and gathers in the water dripping groove 17 on the lower surface of the support plate 15, and then directly drips down into the water body, preventing external water from entering the vertical shaft 3 and not affecting the ventilation of the vertical shaft 3.

[0056] As Figure 6 shown, the floating body limiter 2 includes a fixed cylinder 21, a connecting glue 26, and an ecological sticker 27.

[0057] The connecting glue 26 is fixedly arranged on the outer wall of the vertical shaft 3. The thickness of the connecting glue 26 is not less than 5 mm. It can not only play a buffering role to reduce the direct impact caused by hard contact, but also has a certain flexibility to adapt to the expansion or contraction of the material caused by environmental temperature changes, effectively preventing stress concentration caused by temperature changes in the structure.

[0058] The fixed cylinder 21 is cuboid-shaped. The fixed cylinder 21 is sleeved on the outer wall of the vertical shaft 3 through the connecting glue 26. The top end of the fixed cylinder 21 is flush with the top end of the vertical shaft 3. At the same time, the fixed cylinder 21 is fixedly connected to the outer wall of the vertical shaft 3 through a fixing member 28 to prevent the position deviation or flipping of the fixed cylinder 21 caused by water flow or other external forces. In this embodiment, the fixing member 28 is a screw.

[0059] A slot 22 is opened in the barrel wall of the fixed cylinder 21. A second buffer magnet 24 is fixedly arranged at the bottom of the slot 22. A plurality of speed-limiting magnets 25 are fixedly arranged on the two inner walls of the slot 22. The speed-limiting magnets 25 are arranged at intervals in the height direction. The speed-limiting magnets 25 arranged on the inner wall of the slot 22 close to the vertical shaft 3 and the speed-limiting magnets 25 arranged on the inner wall of the slot 22 far from the vertical shaft 3 are arranged in a staggered manner, thus forming a "pin" shaped arrangement structure. The lower end of the floating barrel 12 is inserted into the slot 22 and can move up and down in the slot 22.

[0060] Among them, the polarity of the lower end of the first buffer magnet 11 is the same as the polarity of the upper end of the second buffer magnet 24. When the first buffer magnet 11 moves downward and approaches the bottom of the slot 22, the first buffer magnet 11 and the second buffer magnet 24 repel each other, and the second buffer magnet 24 can play a buffering role; the polarity of the opposite end of the speed limiting magnet 25 on the two inner walls of the slot 22 is the same as the polarity of the lower end of the first buffer magnet 11. It can be understood that during the descent of the first buffer magnet 11, the lower end of the first buffer magnet 11 and the speed limiting magnet 25 below it repel each other, and the upper end of the first buffer magnet 11 and the speed limiting magnet 25 above it attract each other, thereby slowing down the descent speed of the float 12. Therefore, by setting the second buffer magnet 24 and the speed limiting magnet 25, a magnetic buffer zone is formed inside the slot 22, which effectively slows down the movement speed of the float 12, thereby avoiding impact damage caused by excessive movement speed.

[0061] In order to prevent external water from entering the slot 22, two sealing rings 23 are set on the inner wall of the slot 22 near the top. The two sealing rings 23 are respectively sealed with the inner wall and outer wall of the float 12 to prevent water from entering the slot 22, protect the internal structure from water erosion, and extend the service life of the equipment.

[0062] In order to alleviate the external impact of water flow on the shaft 3 and improve the overall ecological benefits, an ecological sticker 27 is detachably provided on the outer wall of the fixed cylinder 21. The ecological sticker 27 includes a plurality of plate units, and two adjacent plate units are detachably connected by biting, and the plate unit is detachably connected to the outer wall of the fixed cylinder 21. A habitat hole is provided on the plate unit, and a connecting hole is provided between two adjacent plate units, and the connecting hole connects the two adjacent habitat holes. The habitat hole and the connecting hole form a complex network of pores and channels, which effectively imitates the ecological characteristics of natural water structures such as coral reefs. The irregular hole shape and the gaps of different sizes can accommodate aquatic organisms of various sizes, thereby meeting the habitat needs of different species. The connectivity between the holes not only provides a path for small aquatic organisms such as small fish and invertebrates to shuttle freely, but also helps to maintain the natural flow of water, which is crucial for the transfer of nutrients and the discharge of waste. This natural environmental dynamic is very important for maintaining ecological balance and promoting the interaction between biological species. The plate units and the plate units and the fixed cylinder 21 are all detachably connected, which is convenient for later maintenance and repair. The modular bite structure can improve the overall mechanical strength and form a tighter connection to resist the physical impact of water flow. The plate units can be connected by a convex + groove bite, such as a dovetail groove, and the plate unit and the fixing tube 21 can be connected by plugging.

[0063] It should be noted that in order to ensure that the shaft 3 protection device can operate effectively under various water level conditions, especially in flood conditions, in this embodiment, the height of the buoy 12 is set to 0.2 meters, the height of the float limiter 2 is set to 0.5 meters, and the total height reaches the requirement of exceeding the conventional flood level by 0.7 meters. Such a height setting not only ensures the stability and functionality of the buoy 12 when the water level fluctuates, but also takes into account the necessary standards for flood control safety. In addition, the height of the buoy 12 can be adjusted according to the actual use environment and needs to ensure its applicability and effectiveness in different scenarios.

[0064] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
