Description

Technical Field

[0001] The invention relates to the technical field of information transmission equipment, and in particular to a device for stably collecting information inside a water transmission and regulation pipeline under water flow conditions. Background Art

[0002] Water transmission and distribution pipelines are an important part of the national water network. The quality of pipelines is directly related to the safety and stability of the entire project. Regular inspections can timely detect the diseases and problems in the pipeline during operation, ensure the water flow function of the pipeline, and thus ensure the safe operation of the project.

[0003] The existing pipeline navigation and maintenance equipment has a relatively short transmission distance for underwater optical communication due to the confined, narrow and complex pipeline environment. This is mainly due to the strong scattering and absorption of light in water, which causes the optical signal to decay rapidly during transmission, making it impossible to effectively collect information inside the pipeline to detect cracks, damage, and abrasion. Underwater blue-green optical communication is a type of laser communication that uses a blue-green light beam with a wavelength of 450-570nm for communication. The visible light absorption loss in the blue-green band in water is extremely small. Therefore, when blue-green light passes through water, it not only has strong penetration ability, but also has excellent directionality. At present, it has achieved certain research results and applications in deep-sea information transmission. In addition, due to the closed and underwater environment in the pipeline, the navigation receiving equipment in the pipeline can often only collect weak light sources when receiving light source signals. Once the existing light source system is set up, it is difficult to flexibly adjust it during use. This means that the optical signal ultimately received by the equipment cannot be automatically adaptively adjusted, resulting in a loss in light source detection and reception.

[0004] In addition, existing pipeline navigation equipment is usually customized according to the size of the pipeline. Due to the diversity of pipeline sizes, different detection equipment needs to be replaced during pipeline inspection. This customized demand not only increases the equipment cost, but also reduces the detection efficiency. At the same time, when the equipment is inspecting, since the inner wall of the pipeline is in a humid environment for a long time, it is easy to breed a moss layer, making the inner wall of the pipeline abnormally slippery. This slippery phenomenon has a serious impact on the operation of the detection equipment. On the one hand, the slippage phenomenon will cause the detection equipment to travel unstably in the pipeline, and it is difficult to maintain the predetermined trajectory and speed, thereby affecting the accuracy and reliability of the detection. On the other hand, slippage may also aggravate the wear of the detection equipment, shorten its service life, and increase maintenance costs. At the same time, slippage may also bring safety hazards. If the detection equipment slips and loses control in the pipeline, it may hit the inner wall of the pipeline or other obstacles, causing equipment damage.

[0005] Therefore, a stable information collection device for the internal part of a water transmission and regulation pipeline under water flow conditions is proposed to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the device for stably collecting internal information of a water transmission and regulation pipeline under water flow conditions provided by the present invention has the following beneficial effects: 1. The anti-skid belt design is evenly distributed on the transmission track of the equipment in this scheme. This design is aimed at the moss layer formed on the inner wall of the pipeline due to the attachment of organic matter. When the equipment is running in the pipeline, these anti-skid belts can effectively prevent the equipment from slipping and ensure the stability and safety of the driving process; Compared with the traditional design, this solution can quickly change the support angle between the component transmission device and the inner wall of the pipeline by flexibly adjusting the lateral pushing distance of the component's electric telescopic shaft. This solution design enables the equipment to quickly adapt and be put into use when facing pipelines of different diameters, simply by starting the component's electric telescopic shaft to adjust the support angle. This greatly improves the applicability of the equipment in different pipeline maintenance scenarios. At the same time, the anti-skid effect of the transmission device's crawler track effectively reduces the possible slippage of the equipment during operation and movement. In addition, when the equipment encounters potholes on the inner wall of the pipeline, the elastic buffering function of the compression spring can play an important role, effectively reducing the overall shaking and bumping of the equipment and ensuring the smooth operation. This design undoubtedly brings a new performance improvement to pipeline maintenance equipment.

[0017] 2. This solution adds an L-shaped shock-absorbing plate on the basis of the shock-absorbing mechanism of the anti-collision protection. When the light-collecting transparent protective cover on the light receiving device is subjected to floating objects or collisions, the sliding block buffer mechanism is operated and the L-shaped shock-absorbing plate is driven to move relative to each other. The bottom of the L-shaped shock-absorbing plate and the underwater transmitter are mutually resisted. The bottom of the L-shaped shock-absorbing plate will fit closely with the underwater transmitter component to form a mutually resisting structure. This design of the present invention can significantly reduce the sliding phenomenon caused by the collision of objects, thereby effectively suppressing vibration. When the collision is relatively strong, the mechanism can also quickly "lock" the underwater transmitter component, that is, firmly fix it; Compared with the traditional design, in this solution, when the light-collecting transparent protective cover on the light receiving device collides strongly with an object, the underwater transmitter can be locked through this mechanism. When the device is running in the pipeline, if there is excessive water flow or interference from other external factors, a violent collision may occur between the device and the pipeline. The setting of the present invention can provide effective protection in such cases to prevent damage to the device. 3. The polarizer slides evenly in the light-collecting transparent protective cover. At the same time, the light receiver in the light receiving device is located in the middle of the light receiving device near the polarizer. The arc groove in the multi-functional guide shaft is opened. Compared with the single adjustment mechanism of the prior art, this solution drives multiple polarizers to adjust synchronously through one rotation. When the multi-functional guide shaft rotates, the relative distance of the polarizers can be adjusted synchronously. The synchronously moving polarizers can adjust the direction of the reflected light as needed, which can not only ensure that the light receiver can capture more light, especially in weak light or angle-restricted conditions, but also optimize the light path by precisely controlling the position of the reflector, so that the light can be irradiated to the light receiver more directly and efficiently, reducing light loss.

[0021] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0023] Specifically, Figure 2 As shown, one end of the triangle plate 21 is fixedly connected to a fixed plate 29, and the other end of the triangle plate 21 is rotatably connected to an electric telescopic shaft 22. The fixed plate 29 is fixedly connected to the outer surface of the underwater transmitter 1 at one end away from the triangle plate 21. A buffer spring 23 is sleeved on the outer surface of the electric telescopic shaft 22. One end of the buffer spring 23 is fixedly connected to a slider 24, and the other end of the buffer spring 23 is fixedly connected to the electric telescopic shaft 22. A guide groove is opened in the fixed plate 29, and the middle part of the side of the slider 24 away from the buffer spring 23 is slidably connected to the guide groove of the slider 24. , buffer arms 25 are rotatably connected to both sides of the slider 24, and an auxiliary arm 26 is slidably connected to one end of the buffer arm 25 away from the slider 24, and a compression spring 27 is sleeved on the surface of the buffer arm 25; one end of the compression spring 27 is fixedly connected to the buffer arm 25, and the other end of the compression spring 27 is fixedly connected to the auxiliary arm 26, and the auxiliary arm 26 is rotatably connected to the transmission device 11 at one end away from the buffer arm 25, and the transmission device 11 is symmetrically rotatably connected to support plates 28 on both sides, and the support plate 28 is rotatably connected to the fixed plate 29 at one end away from the transmission device 11; Wherein, the quick adjustment driving mechanism 2 is circumferentially arranged on the outer surface of the underwater transmitter 1; The anti-skid belt design is evenly distributed on the No. 11 track of the transmission device of the equipment in this solution. This design is aimed at the moss layer formed on the inner wall of the pipeline due to the attachment of organic matter. When the equipment is running in the pipeline, these anti-skid belts can effectively prevent the equipment from slipping and ensure the stability and safety of the driving process.

[0024] Compared with the traditional design, this solution can quickly change the support angle between the component transmission device 11 and the inner wall of the pipeline by flexibly adjusting the lateral pushing distance of the component electric telescopic shaft 22. The design of this solution enables the equipment to quickly adapt and be put into use when facing pipelines of different diameters, only by simply starting the component electric telescopic shaft 22 to adjust the support angle, which greatly improves the applicability of the equipment in different pipeline maintenance scenarios. At the same time, the anti-skid effect of the crawler track of the transmission device 11 effectively reduces the possible slippage of the equipment during operation and movement. In addition, when the equipment encounters potholes on the inner wall of the pipeline, the elastic buffering function of the compression spring 27 can play an important role, effectively reducing the overall shaking and bumping of the equipment and ensuring the smooth operation. The design of this solution undoubtedly brings a new performance improvement to the pipeline maintenance equipment.

[0025] Specifically, Figure 4 As shown, the upper surface of the hexagonal block 301 is evenly fixedly connected with a deflection positioning block 302, the outer surface of the deflection positioning block 302 is slidably connected with a clamping plate 304, a sliding groove is opened in the middle of the deflection positioning block 302, and balls 303 are evenly arranged in the sliding groove of the deflection positioning block 302, and the clamping plate 304 is fixedly connected to the bottom of the light receiving device 12 at one end away from the hexagonal block 301; In this solution, by evenly arranging deflection positioning blocks 302 on the circumference of both ends of the underwater transmitter 1, by opening a guide groove between the clamping plate 304 and the deflection positioning block 302, and by adding a ball 303 in the groove, when the underwater transmitter 1 equipment produces a slight slip during operation, the relative action of the anti-collision protection mechanism 3 can slow down the shaking of the underwater transmitter 1 itself, thereby making the light receiving device 12 more stable during use.

[0026] Specifically, Figure 5 As shown, one end of the pressure plate 31 is rotatably connected to the bottom of the hexagonal block 301, and the other end of the pressure plate 31 is rotatably connected to the sliding block 32. The bottom of the sliding block 32 is slidably connected to the underwater transmitter 1. The underwater transmitter 1 is fixedly connected with a sliding shaft 33 near both sides of the sliding block 32. The middle part of the sliding block 32 is symmetrically slidably connected to the outer surfaces of both sides of the sliding shaft 33. A reset spring 34 is sleeved in the middle part of the sliding shaft 33, and both ends of the reset spring 34 are fixedly connected to the sliding block 32. In this solution, a buffer device is added at the bottom of the light receiving device 12, that is, after the underwater transmitter 1 is hit by impurities and floating objects in the water, the sliding block 32 is pressed by the pressure plate 31, which will drive the sliding block 32 to slide relatively on the surface of the sliding shaft 33. The sliding of the sliding block 32 will drive the reset spring 34 to be relatively compressed. The buffering effect of the reset spring 34 can reduce the collision damage of various precision equipment in the underwater transmitter 1.

[0027] Further, a push plate is fixedly connected to one side of the sliding block 32, and an extrusion column 38 is fixedly connected to the push plate. An L-shaped damping plate 35 is arranged on the upper surface of the push plate of the sliding block 32. The middle part of the L-shaped damping plate 35 is slidably connected to the underwater transmitter 1. An extrusion groove 36 is provided on the side of the L-shaped damping plate 35 close to the push plate of the sliding block 32. The extrusion column 38 is slidably connected in the extrusion groove 36. A pressing spring 37 is fixedly connected to the lower surface of the L-shaped damping plate 35. One end of the pressing spring 37 away from the connection point of the L-shaped damping plate 35 is fixedly connected to the underwater transmitter 1. In this solution, an L-shaped shock absorbing plate 35 is added on the basis of the shock absorption of the anti-collision protection mechanism 3. When the light-collecting transparent protective cover 45 on the light receiving device 12 is subjected to floating objects or collisions, the buffer mechanism of the sliding block 32 is operated and the L-shaped shock absorbing plate 35 is relatively displaced. The bottom of the L-shaped shock absorbing plate 35 and the underwater transmitter 1 are mutually resisted. The bottom of the L-shaped shock absorbing plate 35 will fit closely with the underwater transmitter 1 component to form a mutually resisting structure. This design of the present invention can significantly reduce the sliding phenomenon caused by the collision of objects, thereby effectively suppressing vibration. When the collision is relatively strong, the mechanism can also quickly "lock" the underwater transmitter 1 component, that is, fix it firmly. Compared with the traditional design, when the light-collecting transparent protective cover 45 on the light receiving device 12 of this solution collides strongly with an object, the underwater transmitter 1 can be locked by this mechanism. When the equipment is running in a pipeline, if it encounters excessive water flow or interference from other external factors, a violent collision may occur between the equipment and the pipeline. The setting of the present invention can provide effective protection in such cases to prevent damage to the equipment. In addition, this mechanism can reduce the risk of damage caused by collision inside the equipment and ensure the stability and durability of the equipment. Such improvements will undoubtedly greatly enhance the safety and reliability of the equipment, enabling it to better adapt to various complex pipeline environments.

[0028] Specifically, Figure 7 As shown, a micro motor is installed in the light receiving device 12, and a light collecting transparent protective cover 45 is fixedly connected to the outer side of the light receiving device 12 away from the clamping plate 304, one end of the multifunctional guide shaft 41 is fixedly connected to the micro motor driving shaft, and the other end of the multifunctional guide shaft 41 is rotatably connected to the light collecting transparent protective cover 45; A polarizer 43 is evenly and slidably connected in the light-collecting transparent protective cover 45, a guide post 44 is fixedly connected to the side of the polarizer 43 close to the multifunctional guide shaft 41, an arc groove 42 is evenly opened on the multifunctional guide shaft 41, the guide post 44 is slidably connected in the arc groove 42, a light receiver is installed in the middle of the light receiving device 12, and the light receiver is installed in the middle of the light receiving device 12 close to the polarizer 43, for receiving signals of faint light; Among them, taking into account the impact of underwater height alignment and water environment on the submersible, a photomultiplier tube with a large photosensitive surface and high sensitivity is used as a photoelectric detector. The sensitivity of the receiver reaches above -55 dBm, and the receiving field of view reaches above 60° to ensure that the underwater submersible can stably receive optical signals while moving.

[0029] Among them, the polarizer 43 slides evenly in the light-collecting transparent protective cover 45, and the light receiver in the light receiving device 12 is located in the middle of the light receiving device 12 near the polarizer 43, and is opened through the arc groove 42 in the multi-functional guide shaft 41. Compared with the single adjustment mechanism of the prior art, this solution drives multiple polarizers 43 to be adjusted synchronously through one rotation. When the multi-functional guide shaft 41 rotates, the relative distance of the polarizers 43 can be adjusted synchronously. The synchronously moving polarizer 43 can adjust the direction of the reflected light as needed, which can not only ensure that the light receiver can capture more light, especially in cases where the light is weak or the angle is limited, but also by precisely controlling the position of the reflector, the path of the light can be optimized, so that the light can be irradiated to the light receiver more directly and efficiently, reducing light loss.

[0030] The specific implementation process of the above embodiment is as follows: Before the equipment is operated, the angle of the transmission device 11 is first adjusted according to the size of the inner wall of the pipeline. Since the electric telescopic shaft 22 is electrically connected in series in the circuit, the electric telescopic shaft 22 can be started by the operator to start the control. At this time, the slider 24 can be driven to slide in the guide groove of the fixed plate 29 by starting the electric telescopic shaft 22 to extend and retract. The sliding of the slider 24 can drive the buffer arm 25 to push the transmission device 11 to adjust at different angles. This solution can quickly change the support angle between the component transmission device 11 and the inner wall of the pipeline by flexibly adjusting the lateral pushing distance of the component electric telescopic shaft 22. This solution is designed When facing pipes of different diameters, the equipment can quickly adapt and be put into use by simply starting the electric telescopic shaft 22 to adjust the support angle, which greatly improves the applicability of the equipment in different pipeline maintenance scenarios. At the same time, the anti-skid effect of the crawler of the transmission device 11 effectively reduces the slippage that may occur during the operation and movement of the equipment. In addition, when the equipment encounters potholes on the inner wall of the pipeline, the elastic buffer function of the compression spring 27 can play an important role, effectively reducing the overall shaking and bumping of the equipment and ensuring the stability of operation. This design scheme undoubtedly brings a new performance improvement to the pipeline maintenance equipment. When the equipment is running and begins to inspect the pipeline, if there is liquid floating matter in the pipeline, when the floating matter collides with the light-collecting transparent protective cover 45 at the front end of the light receiving device 12, Figure 5As shown, the buffer mechanism of the sliding block 32 on the sliding shaft 33 can buffer the collision and protect the integrity of the equipment. When the collision is strong, the mechanism can also quickly lock the underwater transmitter 1 component, that is, fix it firmly. Compared with the traditional design, when the light-collecting transparent protective cover 45 on the light receiving device 12 collides strongly with an object, the underwater transmitter 1 can be locked by this mechanism. When the equipment is running in the pipeline, if it encounters excessive water flow or other external factors, a violent collision may occur between the equipment and the pipeline. The arrangement of the present invention can provide effective protection in such cases to prevent damage to the equipment. When the node glimmer in the pipeline is weak, such as Figure 7 As shown, by starting the micro motor in the light receiving device 12, the multifunctional guide shaft 41 can be mobilized to rotate synchronously by rotating the micro motor, and the polarizer 43 can be moved and adjusted by evenly opening a plurality of slide grooves on the multifunctional guide shaft 41. By synchronously moving the polarizer 43, the weak surrounding light can be reflected onto the light receiver, thereby enhancing the photosensitivity of the camera and improving the clarity and brightness of the picture. Compared with the traditional design, this solution can optimize the path of light by precisely controlling the position of the reflector, so that the light can be irradiated onto the light receiver more directly and efficiently, thereby reducing light loss.
