[0021] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Since the medium transported by the sewage pipeline in the epidemic prevention area may contain highly pathogenic microorganisms, once the pipeline flange leaks, it is extremely easy to cause the spread of infectious disease pathogens and pose a risk of cross-infection, seriously threatening the health and safety of medical staff on the ship. However, at present, there is a lack of a protective device that meets the airtightness requirements on the ship, which cannot effectively block the spread of the leaked medium and is difficult to meet the infection control standards in the epidemic prevention area.

[0023] In addition, some pipelines are located in hidden spaces (such as within the wooden sandwich), and leakage problems are difficult to detect in a timely manner, resulting in the inability to quickly locate the contaminated area, delaying disinfection and maintenance, and further exacerbating the infection risk. Therefore, it is urgent to design a reliable sealing and protection scheme for the pipeline flange in the epidemic prevention area sewage pipeline to eliminate the leakage risk and ensure personnel safety and environmental hygiene.

[0024] The embodiment of the present invention provides an epidemic prevention and pollution pipeline protection device, which can timely detect the leakage of the epidemic prevention pipeline a and effectively seal the places where the epidemic prevention pipeline a is prone to leakage, preventing microorganisms from leaking into the air and ensuring personnel safety and environmental hygiene.

[0025] The following will be combined with the Figures 1 to 3 in the specification drawings to

[0026] The present invention provides an anti-epidemic pollution pipeline protection device, comprising: an elastic protective sleeve 1, which is wrapped around the to-be-sealed area of the anti-epidemic pipeline a, and the inner surface is covered with an antibacterial coating, and the antibacterial coating is closely attached to the outer surface of the anti-epidemic pipeline a; a fireproof layer 2, which wraps the elastic protective sleeve 1, and the inner surface is closely attached to the outer surface of the elastic protective sleeve 1; a fixing component 3, which is sleeved on the outer surface of the fireproof layer 2 to fix the fireproof layer 2 and the elastic protective sleeve 1 to the anti-epidemic pipeline a; a sensing component 4, which is arranged on the anti-epidemic pipeline a close to the to-be-sealed area; an alarm component, which is electrically connected to the sensing component 4 and is arranged in the target area; and a controller, which is respectively electrically connected to the sensing component 4 and the alarm component.

[0027] Specifically, the anti-epidemic pollution pipeline protection device includes an elastic protective sleeve 1, a fireproof layer 2, a fixing component 3, a sensing component 4, an alarm component and a controller. The elastic protective sleeve 1 is wrapped around the to-be-sealed area of the anti-epidemic pipeline a to block the leakage of pathogenic microorganisms through the gaps of the anti-epidemic pipeline a. The inner surface is covered with an antibacterial coating, and the antibacterial coating is closely attached to the outer surface of the anti-epidemic pipeline a to inhibit the growth of microorganisms inside the elastic protective sleeve 1. The fireproof layer 2 wraps the elastic protective sleeve 1, and the inner surface is closely attached to the outer surface of the elastic protective sleeve 1 to prevent a fire from igniting the protective sleeve or the contents of the pipeline. The fixing component 3 is sleeved on the outer surface of the fireproof layer 2 to fix the fireproof layer 2 and the elastic protective sleeve 1 to the anti-epidemic pipeline a, improving the stability and sealing performance of the fireproof layer 2 and the elastic protective sleeve 1. The controller is respectively electrically connected to the sensing component 4 and the alarm component. The alarm component is arranged in the target area, and the sensing component 4 is arranged on the anti-epidemic pipeline a close to the to-be-sealed area. The sensing component 4 is used to sense whether the anti-epidemic pipeline a leaks, and sends the monitoring information to the controller. After receiving the monitoring information of the sensing component 4, the controller issues an instruction to the alarm component, and the alarm component reminds the staff to quickly handle the leakage.

[0028] Further, the anti-epidemic pipeline a is provided with a drain valve.

[0029] In some alternative embodiments, the material of the elastic protective sleeve 1 is any one of transparent rubber, transparent thermoplastic polyurethane, transparent fluororubber, polyvinyl chloride and ethylene-vinyl acetate copolymer.

[0030] Specifically, the transparent rubber has dynamic sealing ability. The high-elasticity rubber can closely adhere to the irregular surface of the flange to achieve anti-leakage of the epidemic prevention pipeline a. The transparent rubber is pressure-resistant and corrosion-resistant. The transparent rubber has the characteristics of visualizing and monitoring the state of the epidemic prevention pipeline a in real time to observe the leakage point in real time. The transparent thermoplastic polyurethane has high transparency with a light transmittance of ≥90%, and its elasticity is close to that of rubber. The transparent fluororubber has extreme environmental tolerance, is resistant to acids and alkalis, and can withstand high temperatures of 200°C, with excellent chemical stability. Polyvinyl chloride has low cost, is easy to process, has high transparency with a light transmittance of 85% - 90%, and can be flexibly modified, such as adjusting with plasticizers. Ethylene-vinyl acetate copolymer has the properties of being light and transparent and having good buffering performance, which is suitable for shock absorption requirements.

[0031] In some alternative embodiments, the fireproof layer 2 is a metal fireproof mesh.

[0032] Specifically, as an efficient safety protection material, the metal fireproof mesh has excellent fireproof and flame-retardant properties. Made of stainless steel such as 304, 316 or galvanized steel, it can withstand high temperatures of 800°C - 1200°C, maintain structural integrity in a fire, and effectively block the spread of flames. Due to its low heat conduction characteristics, the porous structure of the metal mesh reduces the heat conduction efficiency and delays the rise of the temperature on the backfire side. It has high strength and impact resistance. The wire diameter is usually 0.5 - 3mm. For example, the tensile strength of 304 stainless steel reaches 500 - 1000MPa, which can resist external force impacts such as falling objects and explosion shock waves. The metal fireproof mesh can block the direct penetration of flames while allowing heat to dissipate through the convection of holes. The hole structure of the metal fireproof mesh destroys the heat conduction path, enabling the metal mesh to maintain structural integrity at high temperatures. The hole structure absorbs vibration energy and reduces metal fatigue. The through-hole design of the metal fireproof mesh reduces the material consumption and can maintain the tensile strength.

[0033] In some alternative embodiments, the metal fireproof mesh includes a metal protective layer, and the metal protective layer is provided with a plurality of through-holes, and the area of the plurality of through-holes is 30% - 70% of the area of the metal protective layer.

[0034] Specifically, the opening rate of the metal fireproof mesh is 30% - 70%, which allows air to flow while blocking fire, avoiding the accumulation of pressure in an enclosed space. It can block the direct penetration of flames while allowing heat to dissipate through the convection of holes. The hole structure of the metal fireproof mesh destroys the heat conduction path, enabling the metal mesh to maintain structural integrity at high temperatures. The hole structure absorbs vibration energy and reduces metal fatigue. The through-hole design of the metal fireproof mesh reduces the material consumption and can maintain the tensile strength.

[0035] Furthermore, the shape of the through-holes formed by the metal fireproof mesh is a round hole or a hexagonal hole. The hexagonal hole has relatively strong anti-shear ability, and the round hole has uniform stress distribution.

[0036] In some optional embodiments, a plurality of through holes are arranged in an array in the metal protection layer.

[0037] Specifically, the array holes are arranged periodically, such as a honeycomb hexagonal array, to avoid stress concentration and improve the tensile strength of the metal mesh. Regular hole arrays can guide the direction of flame diffusion, such as a maze-like hole arrangement, to extend the flame penetration time.

[0038] In some optional embodiments, the metal protective layer is made of stainless steel or galvanized steel.

[0039] Specifically, stainless steel has a long service life and improved fire resistance. 304 stainless steel still maintains 50% strength at 800°C, and the through-hole array design can delay flame penetration to 1.5 hours. The linear expansion coefficient of 304 stainless steel is only 60% of that of galvanized steel, and the hole array structure is not easily distorted at high temperatures. The tensile strength of 304 stainless steel is ≥515MPa, and the through-hole array is optimized to have a higher specific strength than aluminum alloy. Galvanized steel has a lower cost and moderate hardness. Galvanized steel is stable within 300°C, and with a 50% open hole array design, it meets the 0.5-hour fire resistance period, but the cost of galvanized steel is lower.

[0040] In some optional embodiments, the fixing component 3 is at least one of a circular fixing ring, a regular polygonal fixing ring and an elliptical fixing ring.

[0041] Specifically, the circular fixing ring has uniform stress and efficient sealing. The circumferential stress of the circular fixing ring is evenly distributed, and the circular structure has no stress concentration point. When tightening, it can ensure that the metal protective net is balanced and avoid local deformation. The circular fixing ring naturally matches the arc surface of the metal protective net and the rubber protective sleeve to achieve a 360° compression seal without dead angles. The regular polygonal fixing ring can achieve anti-rotation and prevent slipping during installation. The major axis / minor axis ratio of the elliptical fixing ring is maintained at 1.2 to 2.0. The elliptical fixing ring can match the elliptical pipe or eccentric flange to reduce the wrinkles of the elastic protective sleeve 1.

[0042] In some optional embodiments, the fixing component 3 includes a plurality of fixing plates 31 , and the plurality of fixing plates 31 are arranged in sequence along the circumference of their own circumscribed circles to form an annular structure, and any two adjacent fixing plates 31 are fixed by bolts.

[0043] Specifically, multiple fixing plates 31 are arranged in sequence along the circumference of their own circumscribed circles to form an annular structure. The fixing plates 31 can independently fine-tune their angles and positions, thereby achieving deformation compensation and perfectly fitting non-circular flanges such as elliptical and diamond-shaped flanges, with super adaptability. When the pipeline expands and contracts due to heat and cold, the bolted joints between the fixing plates 31 will produce a slight slippage to avoid stress cracking of the overall structure. When a single fixing plate 31 is damaged, only the adjacent bolts need to be removed, reducing the maintenance time limit.

[0044] In some alternative embodiments, the sensing component 4 is any one of an antibody / antigen recognition sensor, an aptamer sensor, a fluorescence-labeled sensor, a Raman spectroscopy sensor, and an impedance microbial sensor.

[0045] Specifically, the controller is electrically connected to the sensing component 4 and the alarm component respectively. The alarm component is disposed in the target area. The sensing component 4 is disposed on the epidemic prevention pipeline a near the area to be sealed. The sensing component 4 is used to sense whether the epidemic prevention pipeline a leaks, and sends the monitoring information to the controller. After receiving the monitoring information of the sensing component 4, the controller issues an instruction to the alarm component, and the alarm component reminds the staff to quickly handle the leak.

[0046] In some alternative embodiments, the alarm component includes an alarm bell and an alarm light. The alarm bell and the alarm light are electrically connected to the controller respectively, and the alarm bell and the alarm light are located in the target area.

[0047] Specifically, the controller is electrically connected to the sensing component 4 and the alarm component respectively. The alarm component is disposed in the target area. The sensing component 4 is disposed on the epidemic prevention pipeline a near the area to be sealed. The sensing component 4 is used to sense whether the epidemic prevention pipeline a leaks, and sends the monitoring information to the controller. After receiving the monitoring information of the sensing component 4, the controller issues an instruction to the alarm component, and the alarm component reminds the staff to quickly handle the leak.

[0048] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
