Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of information transmission equipment, in particular to an internal information stable collection device for water conveying and regulating pipeline under water conveying condition. BACKGROUND

[0002] The water conveying and regulating pipeline is an important part of the national water network. The pipeline quality is directly related to the safety and stability of the entire project. Through regular inspection, the diseases and problems existing in the pipeline during operation can be found in time to ensure the pipeline water conveying function and thus ensure the safe operation of the project.

[0003] The existing pipeline navigation inspection equipment has the problems that due to the closed and complex environment of the pipeline, the transmission distance of underwater optical communication is relatively short, which is mainly due to the strong scattering and absorption of light in water, resulting in rapid attenuation of optical signals in the transmission process, and the internal information of the pipeline cannot be effectively collected to find cracks, damage, erosion and other information. Underwater blue-green light communication is a kind of laser communication, which uses blue-green light beam with wavelength of 450-570nm to communicate. The visible light absorption loss of blue-green wave band in water is very small, so the blue-green light has strong penetration ability and good directivity when passing through water. At present, certain research results and applications have been achieved in deep sea information transmission.

[0004] In addition, due to the influence of the closed and underwater environment in the pipeline, the pipeline navigation receiving equipment can only collect weak light source when receiving the light source signal. Once the existing light source system is set, it is difficult to adjust flexibly during use, which means that the light signal received by the equipment cannot be automatically adjusted in adaptability, resulting in loss of light source detection and reception.

[0005] In addition, the existing pipeline navigation equipment is usually customized according to the size of the pipeline. Due to the diversity of the size of the pipeline, different detection equipment needs to be replaced for detection when the pipeline is detected. Such customized demand not only increases the cost of equipment, but also reduces the detection efficiency. At the same time, when the equipment is detected, the inner wall of the pipeline is in a humid environment for a long time, which is easy to breed moss layer, so that the inner wall of the pipeline becomes abnormally smooth. This slip phenomenon has a serious impact on the operation of the detection equipment. On the one hand, the slip phenomenon will cause the detection equipment to drive unstably in the pipeline, which is difficult to maintain the predetermined trajectory and speed, and thus affects the accuracy and reliability of the detection. On the other hand, the slip may also aggravate the wear of the detection equipment, shorten its service life, increase the maintenance cost, and the slip phenomenon may also bring safety hazards. If the detection equipment slips out of control in the pipeline, it may collide with the inner wall of the pipeline or other obstacles, causing damage to the equipment.

[0006] Therefore, an internal information stable collection device for water conveying and regulating pipeline under water conveying condition is proposed to solve the above problems. SUMMARY

[0023] Compared with the prior art, the water-through condition internal information stable acquisition device for water transmission pipeline provided by the present application has the following beneficial effects:

[0024] 1、The transmission device of the equipment of the scheme is evenly distributed on the track, and the anti-skid belt design is designed for the moss layer formed by the attachment of organic matter on the inner wall of the pipeline. When the equipment runs in the pipeline, the anti-skid belt can effectively prevent the equipment from slipping and ensure the stability and safety of the running process;

[0025] Compared with the traditional design, the support angle between the component transmission device and the inner wall of the pipeline can be quickly changed by flexibly adjusting the transverse pushing distance of the electric telescopic shaft of the component. The design of the scheme enables the equipment to quickly adapt and be put into use when facing different diameter pipelines by simply starting the component electric telescopic shaft to adjust the support angle, greatly improving the applicability of the equipment in different pipeline maintenance scenes. At the same time, the anti-skid effect of the transmission device also effectively reduces the possibility of slipping during the running and moving process of the equipment. In addition, when the equipment encounters the pits on the inner wall of the pipeline, the elastic buffer function of the compression spring can play an important role, effectively reducing the shaking and jolting of the whole equipment, ensuring the stability of the running. The design of the scheme undoubtedly brings new performance improvement to the pipeline maintenance equipment.

[0026] 2、On the basis of the shock absorption of the anti-collision protection mechanism, the L-shaped shock absorbing plate is added. When the light receiving device is hit by floating objects or collisions, the sliding block buffer mechanism operates while driving the relative displacement of the L-shaped shock absorbing plate. The bottom of the L-shaped shock absorbing plate is tightly attached to the underwater transmitter component, forming a mutual resistance structure. This design can significantly reduce the sliding phenomenon caused by object collision, thereby effectively suppressing vibration. When the collision is relatively strong, the mechanism can also quickly "lock" the underwater transmitter component, i.e. firmly fix it;

[0027] Compared with the traditional design, when the light receiving device light collecting transparent protective cover collides with the object, the mechanism can lock the underwater transmitter. When the equipment runs in the pipeline, if it encounters strong water flow or other external interference, the equipment and the pipeline may collide violently. The setting of the invention can provide effective protection in such cases to prevent the equipment from being damaged;

[0028] 3. The polarizing mirror slides evenly within the light-gathering transparent protective cover. Simultaneously, the light receiver in the light receiving device is located near the center of the polarizing mirror. Through the arc-shaped groove in the multi-functional guide shaft, compared to the single adjustment mechanism of existing technologies, this solution drives multiple polarizing mirrors to adjust synchronously with a single rotation. When the multi-functional guide shaft rotates, the relative distance between the polarizing mirrors can be adjusted synchronously. The synchronously moving polarizing mirrors can adjust the direction of reflected light as needed. This not only ensures that the light receiver can capture more light, especially in cases of weak light or limited angle, but also optimizes the light path by precisely controlling the position of the reflector, allowing the light to hit the light receiver more directly and efficiently, reducing light loss.

[0051] The light receiving adjustment mechanism 4 is arranged on the light receiving devices 12, and is used for adjusting the collection intensity of light beams.

[0052] The underwater transmitter 1 adopts a fully-closed waterproof structure.

[0053] Specifically, as Figure 2As shown, one end of the triangular plate 21 is fixedly connected with a fixed plate 29, and the other end of the triangular plate 21 is rotatably connected with an electric telescopic shaft 22. The fixed plate 29 is fixedly connected to the outer surface of the underwater conveyor 1 away from one end of the triangular plate 21. The outer surface of the electric telescopic shaft 22 is sleeved with a buffer spring 23. One end of the buffer spring 23 is fixedly connected with a sliding block 24, and the other end of the buffer spring 23 is fixedly connected to the electric telescopic shaft 22. A guide groove is formed in the fixed plate 29. The middle part of the sliding block 24 away from the buffer spring 23 is slidably connected in the guide groove of the sliding block 24. Buffer arms 25 are rotatably connected to the two sides of the sliding block 24. Auxiliary arms 26 are slidably connected to the ends of the buffer arms 25 away from the sliding block 24. Compression springs 27 are sleeved on the surfaces of the buffer arms 25. One end of each compression spring 27 is fixedly connected to the buffer arm 25, and the other end of each compression spring 27 is fixedly connected to the auxiliary arm 26. The ends of the auxiliary arms 26 away from the buffer arms 25 are rotatably connected to the transmission device 11. The transmission device 11 is symmetrically rotatably connected with support plates 28 on both sides. The ends of the support plates 28 away from the transmission device 11 are rotatably connected to the fixed plate 29.

[0054] The fast adjustment driving mechanism 2 is circumferentially arranged on the outer surface of the underwater conveyor 1.

[0055] The transmission device 11 of the equipment of the present scheme is uniformly distributed with anti-skid belts. The 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, the anti-skid belts can effectively prevent the equipment from slipping and ensure the stability and safety of the running process.

[0056] Compared with the traditional design, the present scheme can quickly change the support angle between the transmission device 11 and the inner wall of the pipeline by flexibly adjusting the transverse pushing distance of the electric telescopic shaft 22. The design of the present scheme enables the equipment to quickly adapt to and be put into use when facing different diameter pipelines by simply starting the electric telescopic shaft 22 to adjust the support angle, greatly improving the applicability of the equipment in different pipeline maintenance scenarios. At the same time, the anti-skid effect of the transmission device 11 also effectively reduces the possibility of slipping during the running and moving process of the equipment. In addition, when the equipment encounters the pits on the inner wall of the pipeline, the elastic buffering function of the compression spring 27 can play an important role in effectively reducing the overall shaking and jolting of the equipment, ensuring the stability of the running. The design of the present scheme undoubtedly brings new performance improvement to the pipeline maintenance equipment.

[0057] Specifically, as shown in the figure, Figure 4 The outer surface of the biasing positioning block 302 is slidably connected with a clamping plate 304. A sliding groove is formed in the middle of the biasing positioning block 302. The biasing positioning block 302 is uniformly provided with a plurality of rolling balls 303 in the sliding groove. The clamping plate 304 is fixedly connected to the bottom of the light receiving device 12 away from the six-prong block 301.

[0058] The scheme is characterized in that the bias positioning blocks 302 are uniformly arranged at the two ends of the underwater transmission device 1, the guide sliding grooves are arranged between the clamping plates 304 and the bias positioning blocks 302, and the rolling balls 303 are additionally arranged in the sliding grooves.

[0059] Specifically, as shown in the figure, the pressing plate 31 is rotatably connected at one end to the bottom of the six-sided block 301, and the other end of the pressing plate 31 is rotatably connected with the sliding block 32. Figure 5 The bottom of the sliding block 32 is slidably connected to the underwater transmission device 1, and the sliding block 32 is slidably connected to the outer surface of the slide shaft 33 on both sides of the middle part.

[0060] In the scheme, the buffer device is additionally arranged at the bottom of the light receiving device 12, that is, after the underwater transmission device 1 is impacted by impurities and plankton in the water, the sliding block 32 is relatively slid on the surface of the slide shaft 33 by the pressing plate 31 pressing the sliding block 32, the reset spring 34 is relatively compressed by the sliding of the sliding block 32, and the collision damage of various precision equipment in the underwater transmission device 1 can be reduced by the buffering effect of the reset spring 34.

[0061] Further, the sliding block 32 is fixedly connected with a push plate, and the push plate is fixedly connected with an extrusion column 38. The L-shaped damping plate 35 is slidably connected to the underwater transmission device 1 in the middle part, the extrusion groove 36 is arranged 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, the pressing spring 37 is fixedly connected to the underwater transmission device 1 at one end away from the connecting point of the L-shaped damping plate 35, and the other end of the pressing spring 37 is fixedly connected to the push plate of the sliding block 32.

[0062] On the basis of the shockproof mechanism 3, the L-shaped damping plate 35 is added, when the light receiving device 12 is impacted by the floating object or the impact, the sliding block 32 buffering mechanism operates and drives the relative displacement of the L-shaped damping plate 35, the bottom of the L-shaped damping plate 35 is tightly attached to the underwater transmitter 1, forming a mutual resistance structure, this design can significantly reduce the sliding phenomenon caused by object impact, thereby effectively suppressing vibration, when the impact is relatively strong, the mechanism can also quickly "lock" the underwater transmitter 1, that is, it is firmly fixed, compared with the traditional design, when the light receiving device 12 is impacted by the object, the mechanism can lock the underwater transmitter 1, when the equipment is running in the pipeline, if it encounters a large water flow or other external interference, the equipment and the pipeline may collide violently, the setting of the application can provide effective protection in such cases to prevent the equipment from being damaged;

[0063] In addition, the mechanism can also reduce the risk of damage caused by collision inside the equipment, ensuring the stability and durability of the equipment, which undoubtedly brings great improvement to the safety and reliability of the equipment, making it better adapt to various complex pipeline environments.

[0064] Specifically, as shown in Figure 7 The light receiving device 12 is fixedly connected with the light collecting transparent protective cover 45 on the outer side away from the clamping plate 304, and the multifunctional guide shaft 41 is fixedly connected at one end to the driving shaft of the micro motor and rotatably connected at the other end to the light collecting transparent protective cover 45.

[0065] The light collecting transparent protective cover 45 is uniformly and slidably connected with the polarizing mirror 43, and the polarizing mirror 43 is fixedly connected with the guide column 44 on the side close to the multifunctional guide shaft 41.

[0066] Among them, considering the underwater height alignment and the influence of water environment on the submarine, a photomultiplier with large photosensitive surface and high sensitivity is used as a photoelectric detector, the sensitivity of the receiver reaches-55 dBm or more, and the receiving field of view reaches 60° or more, to ensure that the underwater submarine can stably receive light signals in a moving state.

[0067] The polarizer 43 slides uniformly in the light collection transparent protective cover 45, and the light receiver in the light receiving device 12 is located near the middle of the polarizer 43, which is opened through the arc-shaped groove 42 in the multifunctional guide shaft 41. Compared with the single adjustment mechanism of the prior art, the scheme can adjust multiple polarizers 43 synchronously by one rotation. When the multifunctional guide shaft 41 rotates, the relative distance of the polarizers 43 can be adjusted synchronously. Through the synchronous movement of the polarizers 43, the direction of the reflected light can be adjusted as needed. Not only can the light receiver capture more light, especially in the case of weak light or limited angle, but also the position of the reflector can be accurately controlled to optimize the path of the light, so that the light can be more directly and efficiently irradiated on the light receiver, reducing light loss.

[0068] The specific implementation process of the above embodiment is as follows:

[0069] Before the device is running, first adjust the angle of the transmission device 11 according to the size of the inner wall of the pipeline. Since the electric telescopic shaft 22 is connected in series in the circuit through electrical connection, the electric telescopic shaft 22 can be started by operating personnel. At this time, the sliding block 24 can slide in the guide groove of the fixed plate 29 by starting the electric telescopic shaft 22, and the buffer arm 25 can push the transmission device 11 to adjust at different angles. The horizontal pushing distance of the electric telescopic shaft 22 can quickly change the support angle between the transmission device 11 and the inner wall of the pipeline. The design of the scheme enables the device to quickly adapt to and be put into use when facing different diameter pipelines by simply starting the electric telescopic shaft 22 to adjust the support angle, greatly improving the applicability of the device in different pipeline maintenance scenarios. At the same time, the anti-skid effect of the track of the transmission device 11 also effectively reduces the possibility of skidding during the running and moving of the device. In addition, when the device encounters the pits of the inner wall of the pipeline, the elastic buffer function of the compression spring 27 can play an important role, effectively reducing the shaking and jolting of the whole device, ensuring the stability of the running. The design of the scheme undoubtedly brings new performance improvement to the pipeline maintenance device;

[0070] When the device is running and starts to maintain the pipeline, when there are liquid plankton in the pipeline, when the plankton collides with the light collection transparent protective cover 45 at the front end of the light receiving device 12, the light collection transparent protective cover 45 can be moved to the left or right through the multifunctional guide shaft 41, and the light receiver in the light receiving device 12 can be moved to the left or right through the multifunctional guide shaft 41, so that the light receiver can capture more light. Figure 5As shown, the impact can be buffered by the sliding block 32 in the sliding shaft 33 buffer mechanism to protect the integrity of the device, and when the impact is more intense, the mechanism can also quickly lock the underwater transmitter 1 components, that is, firmly fix them, relative to the traditional design, when the light receiving device 12 is hit by the transparent protective cover 45, the mechanism can lock the underwater transmitter 1 when the light receiving device 12 is hit by the transparent protective cover 45, when the device is running in the pipeline, if it encounters a large water flow or other external interference, the device and the pipeline may collide violently, and the device can be protected from damage under such circumstances by the present application;

[0071] When the node light 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 rotated synchronously by rotating the micro motor, and the polarizing mirror 43 can be moved and adjusted by the plurality of sliding grooves evenly arranged on the multifunctional guide shaft 41, and the surrounding weak light can be reflected onto the light receiver by synchronously moving the polarizing mirror 43, thereby enhancing the photosensitive ability of the camera and improving the clarity and brightness of the picture, relative to the traditional design, the present application can optimize the path of light by precisely controlling the position of the reflector, so that the light can be more directly and efficiently irradiated onto the light receiver, reducing light loss.
