[0002] Due to its unique mechanical structure and working principle, during the working process of a diesel engine, short-term or local fluctuations and rapid flow of liquids (such as lubricating oil, fuel oil, cooling water and other media) will inevitably occur in the pipeline. Such fluctuations and rapid flow cause great impact on the pressure sensors installed on the pipeline, and are likely to cause damage to the sensors. Usually, a pressure buffering device needs to be installed at the position where the pressure fluctuation is large to protect the sensors.

Detailed implementation manners

[0026] The following will describe the embodiments of the present embodiment in more detail with reference to the drawings. Although some embodiments of the present embodiment are shown in the drawings, it should be understood that the present embodiment can be implemented in various forms and should not be construed as limited to the embodiments described herein. Instead, these embodiments are provided to more thoroughly and completely understand the present embodiment. It should be understood that the drawings and embodiments of the present embodiment are only for exemplary purposes and are not used to limit the protection scope of the present embodiment.

[0027] The following will describe some embodiments of the present invention in detail with reference to the drawings. Without conflict between the embodiments, the features in the following embodiments and the embodiments can be combined with each other. In addition, the step timings in the following method embodiments are only examples and are not strictly limited.

[0028] A buffer device is a specially designed mechanical device used to absorb and mitigate pressure fluctuations and shocks in fluid systems, protecting sensitive sensors and equipment from damage. It usually contains specific fluid paths and buffer cavities, achieving the buffering effect by guiding the smooth flow of fluid and storing and releasing energy. With the development of technology, modern buffer devices are not only smaller in size and easier to install, but also can adapt to different fluid media and working pressures, with higher adaptability and intelligence levels, significantly improving the stability, reliability, and safety of the entire system.

[0029] However, currently, the pressure buffer devices used to protect sensors mainly have simple structures, mainly reducing the impact force on sensors by increasing fluid paths and expanding buffer cavities. Such pressure buffer devices have poor anti-impact effects when facing fluids with large-flow impacts and cannot effectively protect sensors.

[0030] To solve the above problems, an embodiment of the present utility model provides an anti-impact device for marine engine sensors, solving the problem in the related technology that the anti-impact effect is poor when facing fluids with large-flow impacts and cannot effectively protect sensors.

[0031] Figure 1 This is a schematic structural diagram of an anti-impact device for marine engine sensors provided by an embodiment of the present utility model. As Figure 1 shown, the antenna body of the trapezoidal diagonal line includes a sealed box 1 and an anti-impact component 2.

[0032] The anti-impact component 2 is arranged inside the sealed box 1, and the sealed box 1 and the anti-impact component 2 are configured as a detachable structure.

[0033] The anti-impact device for marine engine sensors in this embodiment can be used for marine engine sensors, specifically for preventing sensors from being impacted by liquids. The anti-impact device mainly includes a sealed box 1 and an anti-impact component 2, and the above-mentioned sealed box 1 and anti-impact component 2 are detachable, facilitating maintenance and replacement of different types of anti-impact components 2 to adapt to different application scenarios. The anti-impact component 2 is located inside the sealed box 1, and the sealed box 1 is used to fix and protect the anti-impact component 2. When the liquid in the engine flows into the sealed box 1, the anti-impact component 2 can effectively buffer the liquid impact during liquid fluctuations, thereby protecting the sensor.

[0034] In practical applications, optionally, in order to adapt to different application scenarios, the sealed box 1 can be made of materials with excellent corrosion resistance, such as stainless steel or nickel alloy. In addition, in order to cope with high-pressure environments, the wall thickness of the sealed box 1 can be thickened, or a double-layer structure can be adopted to enhance the compressive capacity. For example, using a double-layer titanium alloy sealed box 1 can not only prevent corrosion but also cope with high-pressure environments.

[0035] Figure 2 The structural schematic diagram of a sealing box provided by an embodiment of the present utility model. As Figure 2 shown, liquid inlet plates 3 and liquid outlet plates 4 are respectively arranged at two ends of the sealing box 1. Liquid inlet holes 5 are formed on the liquid inlet plates 3, and liquid outlet holes 6 are formed on the liquid outlet plates 4.

[0036] In this embodiment, liquid inlet plates 3 and liquid outlet plates 4 are respectively arranged at two ends of the sealing box 1. The above-mentioned liquid inlet plates 3 and liquid outlet plates 4 are respectively provided with liquid inlet holes 5 and liquid outlet holes 6, allowing liquid to flow through the inside of the device. This design enables the liquid to buffer and flow after entering the device and then flow out from the liquid outlet holes 6, thereby reducing the impact on the sensor.

[0037] In an alternative embodiment, as Figure 1 shown, connecting pipes 7 may be arranged on the liquid inlet holes 5 and the liquid outlet holes 6, and the connecting pipes 7 and the liquid inlet holes 5 or the liquid outlets are configured to be detachably connected.

[0038] Specifically, the connecting pipe 7 is provided with a first connecting section and a second connecting section that are fixedly connected. The first connecting section is used for fixedly connecting with the liquid inlet hole 5 or the liquid outlet hole 6, and the second connecting section is used for connecting with an external pipeline.

[0039] In this embodiment, the connecting pipe 7 includes two parts: a first connecting section and a second connecting section. The first connecting section is used for fixedly connecting with the liquid inlet hole 5 or the liquid outlet hole 6 of the device to ensure the stability of the connection; the second connecting section is used for connecting with an external pipeline to realize the introduction or discharge of liquid.

[0040] In practical applications, the first connecting section and the second connecting section can be designed with different materials to cope with different environmental conditions. For example, the first connecting section can use a metal material such as stainless steel to withstand high temperature and high pressure environments; the second connecting section can use a rubber material with better elasticity to adapt to the thermal expansion and contraction and slight vibration of the external pipeline. In addition, a leak-proof sealing ring can be arranged between the connecting sections to ensure that no liquid leakage occurs during long-term use, and at the same time simplify the connection and disassembly process.

[0041] Figure 3 The structural schematic diagram of an anti-impact component provided by an embodiment of the present utility model. As Figure 3 shown, the anti-impact component 2 is provided with a fixed frame 8 and anti-impact fins 9; the fixed frame 8 is provided with two fixing plates 10, and both of the two fixing plates 10 are vertically arranged with the liquid inlet plate 3 and the liquid outlet plate 4; both ends of the two fixing plates 10 are fixedly connected through connecting plates 11.

[0042] In this embodiment, the impact protection component 2 is composed of a fixed frame 8 and impact protection fins 9. The fixed frame 8 contains two fixed plates 10, and these fixed plates 10 are arranged perpendicular to the liquid inlet plate 3 and the liquid outlet plate 4. The two ends of the two fixed plates 10 are fixedly connected through a connecting plate 11 to ensure the overall stability of the impact protection component 2.

[0043] Optionally, the fixed frame 8 can be made of materials with strong impact resistance, such as high-strength steel or aluminum alloy, to enhance the durability of the overall structure. For example, in a high-pressure liquid environment, manufacturing the fixed frame 8 with aerospace-grade aluminum alloy can effectively reduce the weight of the device while ensuring sufficient strength.

[0044] In an alternative embodiment, sealing gaskets 12 are provided on both sides of the impact protection component 2; reinforcing ribs 13 are provided at the connection between the fixed frame 8 and the connecting plate 11.

[0045] The sealing gaskets 12 on both sides of the impact protection component 2 can increase the sealing performance between the impact protection component 2 and the sealing box 1, thereby ensuring that the liquid does not leak from both sides of the impact protection component 2 during the flow process, and also helping to reduce the impact of the liquid on the edges of the component.

[0046] Optionally, the sealing gasket 12 can adopt a multi-layer composite material structure. For example, in an environment that needs to withstand high pressure and high temperature, a composite sealing gasket 12 composed of a combination of metal and high-temperature resistant rubber is used. This structure can effectively resist compression deformation and high-temperature aging, ensuring the long-term reliability of the seal. In addition, the sealing gasket 12 can be configured as a replaceable modular structure, which is convenient for quick replacement during maintenance and improves the maintenance efficiency.

[0047] Reinforcing ribs 13 are provided at the connection between the fixed frame 8 and the connecting plate 11, which can increase the structural strength of the entire device and prevent deformation under high pressure or strong impact.

[0048] Optionally, the reinforcing ribs 13 can adopt a grid-like or honeycomb-like structure, so that while increasing the strength, the weight of the device will not be significantly increased. For example, in a high-impact liquid environment, it can be designed as a honeycomb-like reinforcing rib 13 structure made of lightweight aluminum alloy material. This can not only effectively improve the impact resistance performance but also keep the device lightweight. In addition, the design of the reinforcing ribs 13 can be optimized according to the impact direction of the fluid so that it can most effectively resist the liquid impact.

[0049] Figure 4 It is a schematic structural diagram of an impact protection fin provided for the embodiment of the present utility model. As Figure 4 shown, the impact protection fin 9 is provided with a first fin group and a second fin group, and the first fin group and the second fin group are respectively fixed on the two fixed plates 10.

[0050] The main functions of the first fin group and the second fin group in this embodiment are to disperse and buffer the impact force generated by the liquid flow, thereby protecting the sensor from damage.

[0051] In practical applications, the first fin group is provided with a plurality of first fins 14, and the second fin group is provided with a plurality of second fins 15; the plurality of first fins 14 and the plurality of second fins 15 are arranged alternately in sequence from front to back.

[0052] The alternating arrangement structure of the plurality of first fins 14 and the plurality of second fins 15 helps to further disperse the impact force of the liquid flow and provide more effective protection.

[0053] Optionally, the material of the fins can be selected according to the characteristics of the liquid medium. For example, in corrosive liquids, corrosion-resistant materials such as titanium alloy or ceramic-coated fins can be selected to improve the durability of the device. In addition, the material of the fins can be optimized according to the flow characteristics of the fluid. For example, in cases where efficient heat dissipation is required, the fins can be designed as materials with heat conduction functions such as copper or aluminum alloy, so as to assist in the conduction and dissipation of heat while buffering the liquid impact.

[0054] In this embodiment, the plurality of first fins 14 and the plurality of second fins 15 are both fixedly arranged at an angle with the fixing plate 10.

[0055] There is a certain angle setting between the plurality of fins in the first fin group and the second fin group and the fixing plate 10, rather than a simple parallel arrangement. This angle setting can more effectively guide and disperse the liquid flow, thereby reducing the direct impact of the liquid on the sensor.

[0056] Optionally, the angle between the fins and the fixing plate 10 can be specifically set according to the actual use environment. For example, fluid dynamics simulation software can be used to simulate the fluid flow at different angles to find the optimal angle setting for reducing the impact force. If the fluid velocity is high, the fin angle can be set to 45 degrees, 65 degrees, etc.; for low-speed fluids, the angle can be set to 15 degrees, 10 degrees, etc.

[0057] In an alternative embodiment, the plurality of first fins 14 and the plurality of second fins 15 in the first fin group and the second fin group can be designed with different shapes or sizes to adapt to different liquid media. For example, for high-viscosity fluids, wider fins can be designed to increase the contact area of the fluid and slow down the flow rate. For low-viscosity, high-flow-rate liquids, thinner fins can be designed to reduce the resistance during liquid flow while achieving effective impact buffering. In addition, micropores or groove structures can be added to the fin surface, and this design helps to further disperse the impact force brought by the liquid flow.

[0058] Figure 5The structural schematic diagram of an impact-resistant bump provided by an embodiment of the present utility model. As Figure 5 shown, impact-resistant bumps 16 are provided at the ends of a plurality of first fins 14 and a plurality of second fins 15, and the impact-resistant bumps 16 are configured as an arc structure.

[0059] Impact-resistant bumps 16 are provided at the end of each fin, and these bumps are designed as an arc structure. The impact-resistant bumps 16 help to further disperse the impact force generated by the liquid flow and reduce the turbulence effect.

[0060] Optionally, the arc structure of the impact-resistant bumps 16 can also be optimized according to the characteristics of the fluid. For example, for high-viscosity liquids, the arc structure can be designed as a circular arc with a larger curvature to extend the liquid flow path and increase the buffering effect. For low-viscosity and high-speed flowing liquids, the bumps can be designed as an ellipse with a smaller curvature to reduce the resistance of the liquid flow. At the same time, the surface of the bumps can be treated with a Teflon coating to reduce liquid adhesion and friction, thereby further reducing the impact.

[0061] Figure 6 The structural schematic diagram of a sealing cover provided by an embodiment of the present utility model. As Figure 6 shown, a sealing cover 17 is provided on one side of a sealing box 1, and a sealing strip 18 is provided between the sealing box and the sealing cover 17. First bolt holes are opened at the four corners of the sealing box 1, and second bolt holes adapted to the first bolt holes are opened on the sealing cover 17; the sealing box 1 and the sealing cover 17 are fixedly connected by fixing bolts arranged in the first bolt holes and the second bolt holes.

[0062] In this embodiment, the sealing strip 18 can be made of high-temperature resistant or corrosion-resistant materials. For example, in a hydrothermal flow system, a fluororubber sealing strip 18 can be used, and this material can withstand a temperature of up to 300 °C and has good chemical corrosion resistance. At the same time, the design of the sealing cover 17 can include a pressing device, such as a spring-loading mechanism, to ensure that the sealing effect of the sealing strip 18 is not affected by the thermal expansion of the device or the aging of the material during long-term use.

[0063] Bolt holes are provided at the four corners of the sealing box 1, and corresponding bolt holes are also provided on the sealing cover 17, and the two are connected by bolts. This design ensures that the sealing cover 17 and the sealing box 1 can be tightly connected to further prevent liquid leakage.

[0064] Optionally, high-strength stainless steel or titanium alloy can be selected as the materials for the bolts and bolt holes to cope with the high humidity and corrosiveness in the marine environment. For example, in a system using seawater as a cooling medium, titanium alloy bolts can not only provide sufficient strength but also prevent the bolts from rusting and failing under long-term seawater contact. At the same time, a lock washer can be added at the bolt connection to ensure that the sealing cover 17 does not loosen under long-term vibration or thermal cycling conditions.

[0065] In an alternative embodiment, the sealing box 1 and the anti-shock component 2 can also be an integral structure. In practical applications, machining by a machine tool can be adopted. This machining method can effectively ensure the integrity of the internal structure and will not cause large deformation, but it has high requirements for machining accuracy and requires the machining personnel to have high machining capabilities.

[0066] Based on the above marine engine sensor anti-shock device, it can protect the sensors in the marine engine from damage by alleviating and dispersing the impact force generated by the liquid flow.

[0067] The liquid first enters the device through the liquid inlet hole 5 at one end of the sealing box 1. The liquid inlet hole 5 can ensure that the liquid forms a certain flow direction and pressure when flowing in. At the same time, the liquid outlet hole 6 at the other end of the device allows the liquid to flow out smoothly. During the process of the liquid flowing through the device, due to the design of the internal structure, the flow rate and pressure of the liquid will both decrease, thereby reducing the impact force.

[0068] Specifically: when the liquid enters the sealing box 1 through the liquid inlet hole 5, its flow rate is relatively high and the pressure is also relatively large. However, after passing through the multi-layer structure (fins, fixed frames, etc.) of the internal anti-shock component 2, the liquid flow path is extended and dispersed, the flow rate gradually slows down, the impact force decreases accordingly, and finally it flows out smoothly from the liquid outlet hole 6.

[0069] The anti-shock fins 9 in the anti-shock component 2 play a core buffering role. The fins are designed to be arranged alternately and at a certain angle with the fixing plate 10. This design not only changes the flow direction of the liquid but also increases the contact area of the liquid in the device and extends the residence time of the liquid in the device. Through the layer-by-layer buffering of the fin group, the energy of the liquid is gradually consumed, and the smoothness of the flow is significantly improved.

[0070] Specifically: when the liquid enters the anti-shock component 2, it first encounters the first layer of fins of the fin group. Due to the angle design of the fins, the liquid is forced to change the flow direction, and part of its kinetic energy is consumed. As the liquid continues to flow through the subsequent fin groups, the kinetic energy is gradually reduced layer by layer, and the flow gradually becomes smooth. The anti-shock bumps 16 at the end of the fins further disperse the remaining impact force to ensure that the impact on the sensor by the liquid is minimized.

[0071] The sealing structure between the sealed box 1 and the shock-proof component 2 ensures the sealing of the entire device and prevents liquid leakage. At the same time, the design of the sealing strip 18 and the gasket 12 ensures that in a high-pressure, high-temperature or corrosive liquid environment, the liquid inside the device will not overflow and will not pollute the external environment. Protected by the sealing structure, the device can operate stably for a long time.

[0072] Specifically: When the liquid flows inside the device, the sealing strip 18 and the gasket 12 ensure that the liquid is completely enclosed inside the device, preventing the liquid from leaking from the joints or gaps. Even under pressure changes or temperature fluctuations, the sealing structure can still maintain airtightness, ensuring the long-term stable operation of the device.

[0073] Reinforcing ribs 13 are provided between the fixed frame 8 and the connecting plate 11 of the device, improving the structural strength of the entire device. This structure prevents the internal structure of the device from deforming under the impact of high-pressure or large-flow liquid, thus ensuring the long-term durability of the device.

[0074] Specifically: During the process of the liquid flowing through the shock-proof device, the impact force of the liquid is evenly dispersed to the entire device structure through the fixed frame 8 and the reinforcing ribs 13. The presence of the reinforcing ribs 13 avoids the stress concentration phenomenon of the structure, enabling the device to maintain a stable shape and strength during long-term operation, and being not easily deformed or damaged.

[0075] When the liquid enters the shock-proof device, it first enters the sealed box 1 through the liquid inlet hole 5. Here, the flow rate and pressure of the liquid are relatively high. As the liquid enters the internal shock-proof component 2, the staggered fins buffer and disperse the impact force of the liquid layer by layer, and the arc-shaped bumps at the ends of the fins further slow down the kinetic energy of the liquid. Finally, after a series of buffering and the extension of the flow path, the liquid flows out from the liquid outlet hole 6 at a relatively stable speed. During the whole process, the sealing structure ensures that the liquid will not leak, while the reinforcing ribs 13 provide the necessary structural support to prevent the device from deforming or being damaged under a long-term high-pressure environment. This design effectively protects the sensor installed on the liquid pipeline and extends its service life.
