Description

Technical Field

[0001] This utility model belongs to the field of water intake channel engineering inspection technology, and in particular relates to a mobile inspection device for inspecting the lining structure of water intake channels. Background Technology

[0002] During the construction, operation, and maintenance of water intake channels, the lining structure is the core load-bearing and protective component. It mainly includes primary and secondary lining, and its function is to withstand the pressure of the surrounding rock, prevent deformation and collapse of the surrounding rock, and isolate groundwater seepage, ensuring the long-term stability and durability of the water intake channel structure. The construction quality of the lining structure directly determines the safe operation level of the water intake channel. Therefore, during the construction phase, it is crucial to conduct comprehensive and accurate testing of the integrity, thickness, and internal defects (such as voids and cracks) of the lining structure. This is a key step in ensuring the quality of the water intake channel project meets standards and avoiding potential safety hazards.

[0003] Currently, the inspection of water intake channel lining structures (especially the secondary lining) mostly adopts traditional construction inspection techniques. The specific operation method is as follows: the inspection unit brings the inspection equipment to the construction site, and the construction unit first welds a test support through steel pipes and fixes the support inside the loader bucket to form a temporary inspection carrier. During the inspection, the loader moves the support inside the water intake channel, and the inspection personnel need to climb to the top of the support and use handheld inspection instruments (such as radar detection instruments) to inspect the entire section of the water intake channel lining structure, thereby realizing the inspection of the lining structure quality.

[0004] The aforementioned traditional testing methods have significant drawbacks, specifically in the following aspects: First, testing personnel must be positioned at a high altitude above the support structure without any safety protection measures, posing an extremely high risk of falling from height and making it impossible to effectively guarantee personnel safety; second, the stability of the testing support structure depends entirely on the operator's skill level, and insufficient operational precision or sudden operational errors may cause the support structure to sway or tilt, further increasing the risk of personnel losing balance and falling from the support structure; in addition, when the loader moves within the water intake channel to assist in testing, it easily occupies the construction space of the water intake channel, interfering with the normal construction process of the water intake channel and affecting the overall construction progress. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, one aspect of this application proposes a mobile inspection device for inspecting the lining structure of a water intake channel, comprising: The scaffolding is equipped with wheels and adjustable tracks. The wheels are used to roll on the tracks in the water intake channel so that the scaffolding can move along the length of the tracks. The adjustable tracks are set along the width of the water intake channel. The adjusting bracket is slidably mounted on the adjusting track. The testing instrument is mounted on the adjustment bracket. A drive assembly is mounted on the scaffold; the drive assembly is used to move the adjusting bracket along the adjusting track; the drive assembly includes: A winch is installed on the scaffolding. The drive cable is connected to a winch at one end, which is used to wind up and unwind the drive cable; the end of the drive cable away from the winch is connected to an adjustment bracket. The scaffolding has a first end and a second end at its two ends in the width direction of the water intake channel. The second end is located below the middle of the inner top surface of the water intake channel. The adjusting rail extends smoothly from the bottom of the first end to the top of the second end so that the adjusting rail matches the inner top surface of the water intake channel. The winch is located at the bottom of the second end. The drive cable extends upward from the winch to the upper side of the top of the second end, and then extends to the adjusting bracket.

[0007] In this technical solution, the structural design integrates a traveling wheel, an adjusting track, and a winch drive cable. This enables the testing equipment to move within the water intake channel and adjust its lateral position. The adjusting track is located on the upper side of the scaffold and matches the curved top surface of the water intake channel, ensuring that the testing instrument can cover the entire cross-section of the water intake channel for testing without requiring personnel to climb to heights, thus avoiding the risk of falls from heights. By controlling the movement of the adjusting support through cable winding / unwinding, the movement of the testing instrument can be ensured to be smooth, allowing for fast and accurate testing. The scaffolding provides ample space, facilitating other construction work within the scaffold without interfering with other construction work within the water intake channel.

[0008] In some embodiments, the scaffolding is provided with longitudinal support beams, and the adjusting rails are provided on the longitudinal support beams; Multiple longitudinal support beams are installed, and these beams are installed sequentially along the width of the water intake channel, with their height gradually increasing from the first end to the second end. When the adjusting bracket is located at one end of the adjusting track near the first frame end, the drive cable is attached to the upper surface of multiple longitudinal support beams.

[0009] In the technical solution, the structural design raises the longitudinal support beams in stages, so that the adjustment track forms an arc-shaped trajectory that fits with the top surface of the water intake channel. Furthermore, the multi-stage support beams distribute the force, reduce the risk of track deformation, and enhance track stability. On the other hand, the longitudinal support beams optimize the path of the drive cable, allowing the drive cable to extend along the upper surface of the longitudinal support beams, avoiding interference and ensuring smooth movement.

[0010] In some embodiments, multiple longitudinal support beams are sequentially spaced from one end of the adjustment track to the other end; the ends of adjacent longitudinal support beams are connected by straight rod-shaped transverse support beams.

[0011] In the technical solution, the structural design forms a grid-like frame, which improves the overall rigidity of the scaffolding and prevents the track from deviating due to torsion or vibration during movement. On the other hand, the straight connection between the ends of the longitudinal support beams makes the adjusting track protrude upward relative to the transverse support beams, so that the adjusting track protrudes upward relative to the main structure of the scaffolding. This ensures that the adjusting support is closer to the top surface of the water intake channel, reduces the distance between the detector and the top surface of the water intake channel, and makes it easier for the detector to inspect the end face of the water intake channel.

[0012] In some embodiments, the adjusting track is provided with transverse support beams on both sides along the length of the water intake channel.

[0013] In the technical solution, the structural design reinforces both ends of the longitudinal support beam to prevent the adjustment track from shaking and improve its stability, thereby ensuring the stability of the detector's trajectory as it moves along the adjustment track with the adjustment bracket.

[0014] In some embodiments, the scaffolding is provided with horizontal support beams; the remaining longitudinal support beams, whose height position is lower than the second longitudinal support beam from the top, are all connected to the horizontal support beams.

[0015] In the technical solution, the structural design connects the horizontal support beam to the lower longitudinal support beam, supporting the wider part of the scaffold bottom to form a bottom reinforcement layer, improving the stability of the scaffold, distributing the bottom load, and reducing the pressure of the traveling wheels on the ground of the water intake channel.

[0016] In some embodiments, the scaffolding is provided with vertical support beams; the remaining longitudinal support beams, which are positioned at a height higher than the second longitudinal support beam from the bottom, are all connected to vertical support beams.

[0017] In the technical solution, the structural design connects the vertical support beam to the high-level longitudinal support beam to form a top support system, which supports the arc-shaped section at the top of the water intake channel and reduces track sagging deformation.

[0018] In some embodiments, a guide plate is further included; a base frame is horizontally disposed at the bottom of the scaffold; the guide plate is located below the base frame and connected to one end of the base frame near the first frame end; the guide plate is used to extend into a drainage ditch disposed at the bottom of the water intake channel and is configured to slide on the inner wall of the drainage ditch.

[0019] In the technical solution, the structural design allows the scaffolding to be further supported by the guide plate, thereby improving the overall stability of the scaffolding; secondly, the existing drainage ditch is used for positioning and guidance, which improves the stability of the scaffolding as it moves in the water intake channel; in addition, the guide plate is used as a counterweight at a low position to improve the stability of the scaffolding when the detector is at a high position.

[0020] In some embodiments, the base frame is provided with downwardly extending support legs, and the traveling wheels are located at the bottom ends of the support legs; The outriggers are provided in multiple ways, and the multiple outriggers are divided into outer legs located at the end of the base frame closer to the first frame end and inner legs located at the end of the base frame closer to the second frame end. The outer leg is configured to slide on the outer wall of the drainage ditch.

[0021] In the technical solution, the structural design uses an inner and outer wing layout, so that the outer wing and the guide plate form a clamping guide, which further improves the stability of the scaffolding when it moves in the water intake channel.

[0022] In some embodiments, the adjustment bracket includes: The movable seat is slidably mounted on the adjustment track. The mounting base is located on the side of the movable base away from the adjustment track and is connected to the movable base via a scissor-type linkage mechanism; the detector is mounted on the mounting base.

[0023] In the technical solution, the structural design can adjust the distance between the detector and the top surface inside the water intake channel, compensate for the unevenness of the water intake channel lining surface, ensure that the detection probe maintains a constant distance from the wall, and guarantee the detection effect of the detector on the cross-section of the water intake channel.

[0024] In some embodiments, two regulating rails are provided along the length of the water intake channel, and a drive cable extends between the two regulating rails.

[0025] In the technical solution, the structural design ensures that the two sides of the adjustment bracket move synchronously through the central layout of the dual adjustable rails and cables, avoiding the tilting of the detector caused by the jamming of one side of the rail; on the other hand, it allows the cables to be hidden, reducing the risk of interference between the cables and the equipment in the water intake channel and improving the space utilization rate.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0033] like Figures 1 to 3 As shown in an illustrative embodiment of the mobile inspection device for inspecting the lining structure of a water intake channel according to this utility model, the mobile inspection device includes a scaffold 1. The scaffold 1 is typically a frame structure composed of rods reliably connected by nodes, and is a detachable truss structure that balances lightweight design with torsional rigidity. A walking track (not shown in the accompanying drawings) is typically provided on the ground within the water intake channel. The walking track is usually set along the length of the water intake channel. The scaffold 1 is equipped with wheels 11, which roll on the walking track, allowing the scaffold 1 to move along its length within the water intake channel and change its position. The walking track is typically a grooved track, and the wheels 11 are located within the grooves of the walking track, thus constraining the wheels 11 to always move along the walking track. An adjusting track 12 is also provided on the scaffold 1, which is set along the width of the water intake channel, such that the adjusting track 12 is located laterally on the scaffold 1.

[0034] In some embodiments, the mobile inspection device for inspecting the lining structure of the water intake channel further includes an adjusting bracket 2. The adjusting bracket 2 is mounted on the adjusting track 12, thereby enabling it to move along the adjusting track 12 and change its position in the width direction within the water intake channel. The adjusting track 12 is typically a T-shaped guide rail, and the adjusting bracket 2 is correspondingly provided with a T-shaped groove, so that after the adjusting bracket 2 is assembled with the adjusting track 12, the adjusting bracket 2 slides stably on the adjusting track 12 without detaching from it.

[0035] In some embodiments, the mobile inspection equipment for inspecting the lining structure of water intake channels also includes an inspection instrument (not shown in the accompanying drawings). The inspection instrument is typically an integrated ground-penetrating radar unit, with a built-in multi-frequency shielded antenna array and a real-time imaging host. It can transmit and receive high-frequency electromagnetic waves, accurately scan the lining thickness, voids, cracks, and reinforcement distribution of the water intake channel. Simultaneously, it automatically records mileage and angles through a ranging encoder and attitude sensor, generating a high-resolution radar profile on-site, enabling rapid and non-destructive diagnosis of the lining quality. The inspection instrument is mounted on an adjusting support 2, thus moving with the adjusting support 2 along the width direction of the water intake channel.

[0036] In some embodiments, the mobile inspection device for inspecting the lining structure of water intake channels further includes a drive assembly 3, which includes a winch 31 and a drive cable 32. The winch 31 is mounted on the scaffold 1. One end of the drive cable 32 is connected to the winch wheel of the winch 31 and partially wound around the winch wheel. The end of the drive cable 32 away from the winch 31 is connected to an adjusting bracket 2, so that when the winch wheel of the winch 31 winds up or unwinds the drive cable 32, the drive cable 32 drives the adjusting bracket 2 to move on the adjusting track 12. The winch wheel of the winch 31 is usually driven to rotate by a motor, but it can also be rotated manually by operating a rocker arm connected to the winch wheel.

[0037] In some embodiments, the two ends of the scaffold 1 in the width direction of the water intake channel are a first end 1-1 and a second end 1-2, respectively. The second end 1-2 is located below the middle of the top surface inside the water intake channel, such that the first end 1-1 is located on the outer side in the width direction of the water intake channel, and the second end 1-2 is located on the inner side in the width direction of the water intake channel. The scaffold 1 occupies about half of the cross-sectional area of ​​the water intake channel.

[0038] In some embodiments, the adjusting track 12 extends smoothly from the bottom of the first end 1-1 to the top of the second end 1-2, so that the adjusting track 12 gradually rises from the outside to the inside. The inner top surface of the water intake channel is generally a smooth surface with an approximate arc shape, gradually decreasing from the middle to both sides, and extending to the two side edges of the ground inside the water intake channel. The adjusting track 12 is generally set on the upper side of the scaffold 1, so as to face the inner top surface of the water intake channel, and the extension of the adjusting track 12 from the first end 1-1 to the second end 1-2 matches the shape of the inner top surface of the water intake channel, both having an approximate arc shape, so that the distance between the adjusting track 12 and the opposite inner top surface of the water intake channel remains substantially the same in the width direction of the water intake channel.

[0039] The winch 31 is located at the bottom of the second frame end 1-2. The drive cable 32 extends upward from the winch 31 to the upper side of the top of the second frame end 1-2, and then extends outward and downward to the adjusting bracket 2. The upper side of the top of the second frame end 1-2 serves as the fulcrum of the drive cable 32 at the highest position of the scaffold 1, so that the winch 31 can be installed at the bottom of the scaffold 1, which facilitates the operation of the winch 31 and enables the driving of the adjusting bracket 2, realizing the raising and lowering of the adjusting bracket 2 in the lateral direction of the scaffold 1.

[0040] This structural design uses wheels 11 to allow the scaffold 1 to carry the detector along the track, enabling the detector to reach different sections of the water intake channel along its length. Furthermore, a winch 31 retracts and extends the drive cable 32, moving the adjusting bracket 2 along the adjusting track 12. This allows the detector to travel along the corresponding sections of the water intake channel, achieving adjustment of the detector's position in both the length and width directions of the channel. The adjusting track 12 is located on the upper side of the scaffold 1 and matches the curved top surface of the water intake channel, ensuring the detector can cover the entire cross-section of the water intake channel for testing without requiring personnel to climb, thus avoiding the risk of falls from heights.

[0041] Scaffolding 1 extends laterally from the outer side to the middle of the water intake channel's cross-section, occupying only about half of the channel's cross-section. This allows the remaining portion of the channel to be used for personnel and material passage and construction within the channel, minimizing the impact of equipment on other construction work. The other side of the water intake channel also requires inspection. Typically, a separate set of mobile inspection equipment is installed within the channel, with two sets positioned on opposite sides of the channel's width. These two sets are usually spaced apart along the channel's length to ensure the passage of personnel and materials. Furthermore, scaffolding 1 uses jointed members, and the gaps between the members facilitate personnel work on the water intake channel's lining structure. Compared to a loader completely occupying the channel's space, this design reduces obstruction to other construction work within the channel.

[0042] The adjusting track 12 gradually rises from the outside to the inside. When the winch 31 retracts the drive cable 32, the drive cable 32 pulls the adjusting bracket 2, carrying the detector, towards the inside of the water intake channel, with the height gradually increasing. When the winch 31 releases the drive cable 32, the drive cable 32 releases the adjusting bracket 2. Under the weight of the adjusting bracket 2 and the detector, both slide down the adjusting track 12, thus moving towards the outside of the water intake channel. This structure simplifies the winch 31's drive mechanism, requiring only the retraction of the drive cable 32 to achieve the reciprocating movement of the detector in the width direction of the water intake channel. It eliminates the need for two cables pulling in two directions, resulting in a simple structure and small footprint.

[0043] In some embodiments, longitudinal support beams 101 are provided on the scaffold 1, with the longitudinal direction of the scaffold 1 being the length direction of the water intake channel. Adjustment rails 12 are provided on the longitudinal support beams 101. Multiple longitudinal support beams 101 are provided, arranged sequentially along the width direction of the water intake channel, such that the longitudinal support beams 101 are arranged one by one along the adjustment rails 12, and the height of the longitudinal support beams 101 gradually increases from the outer first end 1-1 to the inner second end 1-2, so that all longitudinal support beams are located on the upper side of the scaffold 1, opposite to the inner top surface of the water intake channel. When the adjustment bracket 2 is located at the end of the adjustment rail 12 near the first end 1-1, the drive cable 32 is attached to the upper surface of the multiple longitudinal support beams 101, so that the multiple longitudinal support beams 101 support the drive cable 32 located on the upper side of the scaffold 1.

[0044] This structural design utilizes progressively rising longitudinal support beams 101 to support the adjusting track 12 at various positions along the lateral direction of the scaffold 1. This reduces the risk of deformation of the adjusting track 12 and ensures that it forms an arc-shaped trajectory that conforms to the top surface of the water intake channel, enhancing track stability. This prevents changes in the distance between the detector and the top surface of the water intake channel during the lateral movement of the scaffold 1, ensuring stable detection of the water intake channel cross-section. Furthermore, the longitudinal support beams 101 guide the drive cable 32, optimizing its path and ensuring that it extends close to the upper surface of the longitudinal support beams 101. This prevents the drive cable 32 from interfering with the internal structure of the scaffold 1 and ensures smooth movement of the drive cable 32.

[0045] In some embodiments, a plurality of longitudinal support beams 101 are sequentially spaced from one end of the adjusting track 12 to the other end of the adjusting track 12, such that the longitudinal support beams 101 divide the adjusting track 12 into multiple segments, and the longitudinal support beams 101 and the adjusting track 12 form a cross-shaped structure. The ends of adjacent longitudinal support beams 101 are connected by straight rod-shaped transverse support beams 102, further enhancing the connection between the longitudinal support beams 101.

[0046] The structural design forms a grid-like frame at the top of the scaffold 1, consisting of transverse support beams 102, longitudinal support beams 101, and adjusting rails 12. This further enhances the rigidity of the top of the scaffold 1, preventing longitudinal deformation of the adjusting rails 12 due to torsion or vibration during the movement of the scaffold 1 in the water intake channel, thus further improving the stability of the adjusting rails 12. Additionally, as... Figure 2As shown, the transverse support beam 102 is linearly connected to the ends of the longitudinal support beam 101, causing the adjusting track 12 to protrude upward relative to the transverse support beam 102. This ensures that the adjusting track 12 protrudes upward relative to the main structure at the top of the scaffold 1, allowing the adjusting bracket 2 to be closer to the top surface of the water intake channel. This reduces the distance between the detector and the top surface of the water intake channel, making it easier for the detector to inspect the end face of the water intake channel. It also keeps the main structure at the top of the scaffold 1 away from the top surface of the water intake channel, providing sufficient space for the adjusting bracket 2 and the detector to move and be maintained.

[0047] In some embodiments, the adjusting track 12 is provided with transverse support beams 102 on both sides along the length of the water intake channel. This structural design ensures that both ends of the longitudinal support beam 101 are reinforced by the transverse support beams 102, preventing the adjusting track 12 from shaking and improving its stability, thereby ensuring the stability of the detector's trajectory as it moves along the adjusting bracket 2 on the adjusting track 12.

[0048] In some embodiments, horizontal support beams 103 are provided on the scaffold 1. All other longitudinal support beams 101 whose height is lower than the second longitudinal support beam 101 from top to bottom are connected to the horizontal support beams 103. This structural design ensures that, except for the highest and second highest longitudinal support beams 101, the remaining relatively low-lying longitudinal support beams 101 receive horizontal support from the horizontal support beams 103. Since the height of the longitudinal support beams 101 gradually decreases and they extend inwards and outwards, the horizontal distance between the lower longitudinal support beams 101 and the second end 1-2 is relatively large. The horizontal support beams 103 connect the two, thereby supporting the wider section at the bottom of the scaffold 1, forming a bottom reinforcement layer, improving the stability of the bottom of the scaffold 1, and dispersing stress to both sides through the horizontal support beams 103, which in turn distribute the stress to the ground of the water intake channel through the walking wheels 11, preventing excessive pressure concentration on the water intake channel ground.

[0049] In some embodiments, vertical support beams 104 are provided on the scaffold 1. All other longitudinal support beams 101, whose height is higher than the second longitudinal support beam 101 from the bottom, are connected to the vertical support beams 104. This structural design ensures that, except for the lowest and second lowest one, the remaining relatively high longitudinal support beams 101 are all supported vertically by the vertical support beams 104, forming a top support system for the scaffold 1. This strengthens the support for the curved section at the top of the water intake channel, reduces track sagging deformation, ensures smooth movement of the detector, and maintains the distance between the detector and the top surface of the water intake channel.

[0050] In some embodiments, the mobile inspection device for inspecting the lining structure of the water intake channel further includes a guide plate 4. A base frame 13 is horizontally mounted at the bottom of the scaffold 1, and the guide plate 4 is located below the base frame 13 and connected to one end of the base frame 13 near the first frame end 1-1. A drainage ditch is typically provided at the point where the top surface of the water intake channel extends outward and downward and connects with the edge of the ground within the water intake channel, serving as a drainage facility within the water intake channel. The guide plate 4 extends into the drainage ditch, and its inner surface adheres to the inner wall of the drainage ditch, allowing the drainage ditch to guide the guide plate 4 to slide along the length of the water intake channel, thereby enhancing the constraint on the movement of the scaffold 1 within the water intake channel and improving the stability of the scaffold 1's movement. On the other hand, when the detector and the adjusting bracket 2 move inward to the height of the scaffold 1, the center of gravity of the overall structure of the walking detection equipment will shift inward and upward, causing the scaffold 1 to easily tilt inward. The guide plate 4, which is located at the lower position on the outside, can act as a counterweight to balance the aforementioned shift in the center of gravity and keep the scaffold 1 stable, that is, to improve the stability of the scaffold 1 when the detector is at a high position.

[0051] In some embodiments, the base frame 13 is provided with downwardly extending support legs 14, and the traveling wheels 11 are located at the bottom ends of the support legs 14, thereby ensuring that the base frame 13 is spaced from the ground inside the water intake channel, and the space between the two can accommodate the guide plate 4, preventing the guide plate 4 from touching the bottom and increasing the resistance of the scaffold 1 in its movement. Multiple support legs 14 are provided, divided into outer legs 14-1 located at the end of the base frame 13 near the first frame end 1-1 and inner legs 14-2 located at the end of the base frame 13 near the second frame end 1-2. The outer legs 14-1 are configured to slide on the outer wall of the drainage ditch. This structural design, through the inner and outer layout of the support legs 14, provides more sufficient support for the scaffold 1, ensuring the stability of the scaffold 1. Furthermore, the outer legs 14-1 and the guide plate 4 slide on the inner and outer surfaces of the drainage ditch respectively, forming a clamping guide, further improving the stability of the scaffold 1 in its movement within the water intake channel.

[0052] In some embodiments, the adjusting bracket 2 includes a movable base 21 and a mounting base 22. The movable base 21 is slidably disposed on the adjusting track 12, and the mounting base 22 is disposed on the side of the movable base 21 away from the adjusting track 12 and is connected to the movable base 21 via a scissor-type linkage mechanism 23. The detector is disposed on the mounting base 22. When the detector needs to contact the inner lining of the water intake channel for detection, a spring is usually installed between the movable base 21 and the mounting base 22. The spring pushes the mounting base 22 to make the detector adhere to the inner lining of the water intake channel. When the detector moves, it undulates with the inner lining of the water intake channel, and the spring deforms accordingly, causing the scissor-type linkage mechanism 23 to extend and retract. When the detector does not need to contact the inner lining of the water intake channel for detection, the scissor-type linkage mechanism 23 is usually connected to a driving element, which is usually a motor and a push-pull rod. By driving the connecting rod in the scissor-type linkage mechanism 23 to swing, the scissor-type linkage mechanism 23 extends and retracts, changing the distance between the movable base 21 and the mounting base 22, and adjusting the distance between the detector and the inner lining of the water intake channel. This structural design allows for adjustment of the distance between the detector and the top surface inside the water intake channel, compensating for unevenness in the lining surface of the water intake channel, ensuring a constant distance between the detector probe and the wall, and guaranteeing the detector's effectiveness in detecting the cross-section of the water intake channel.

[0053] In some embodiments, two adjusting rails 12 are arranged along the length of the water intake channel, and the drive cable 32 extends between the two adjusting rails 12. This structural design, with the dual adjusting rails 12 and the cable centrally positioned, ensures that both sides of the adjusting bracket 2 move synchronously, avoiding tilting of the detector caused by jamming on one side of the rail; in addition, the drive cable 32 is hidden between the two adjusting rails 12, reducing the risk of interference between the drive cable 32 and the equipment in the water intake channel, and improving space utilization.

[0054] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
