This application will now be described with reference to the accompanying drawings.

[0091] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0092] As an auxiliary facility connecting to drainage pipes, the health of drainage inspection wells directly affects the operational efficiency and safety of the entire drainage system. They not only provide a necessary entry point for pipe maintenance but also bear the important responsibility of monitoring pipe conditions and preventing blockages and leaks. However, due to external environmental influences, drainage inspection wells often suffer from defects such as well wall corrosion, structural layer detachment, and water leakage. Well wall corrosion is mainly caused by the chemical reaction between minerals, acidic or alkaline substances in groundwater and the well wall material. This corrosion gradually weakens the strength of the well wall material, and in severe cases, can even lead to perforation, affecting the overall stability of the well. Structural layer detachment is mainly caused by material aging, poor construction quality, or long-term uneven stress. This not only affects the aesthetics of the drainage inspection well but, more importantly, reduces the well's load-bearing capacity, increasing the probability of collapse. Water leakage not only wastes water resources but can also pollute the surrounding environment. Furthermore, long-term leakage accelerates soil erosion around the well, forming cavities and further threatening the safety of the drainage inspection well and its surrounding facilities. These defects not only affect the normal use of drainage inspection wells, but may also cause safety hazards such as cavities around the well, ground subsidence around the well, and uneven settlement of the well body.

[0093] Given the prevalent defects in existing drainage inspection wells, comprehensive and meticulous inspection is crucial. Currently, inspection of drainage inspection wells primarily relies on periscope equipment to acquire images of the well's interior. While this method excels at identifying blockages and observing the well's surface condition, it falls short in assessing the well's structural quality and the development of defects around the well, failing to reflect the well's true operational status. Therefore, specialized inspection equipment, including sensing and detection components, is necessary.

[0094] However, in practical applications, the following technical problems exist. The first technical problem is that it is difficult to ensure the stability of the special detection equipment during the lowering process to the preset position of the drainage inspection well using hoisting tools, which leads to inaccurate detection results of the well body structure quality and the development of defects around the well.

[0095] The second technical problem is that different specialized testing equipment have different working principles and require different hoisting tools to be lowered to the preset position of the drainage inspection well, which results in a long testing time for the quality of the well structure and the development of defects around the well.

[0096] The third technical problem is that when using hoisting tools to lower the specialized testing equipment to the preset position of the drainage inspection well, it is difficult to ensure the distance between the detection components of the specialized testing equipment and the inner wall of the drainage inspection well, resulting in inaccurate detection results of the development of defects around the well.

[0097] Therefore, to address the aforementioned technical issues, the research found that, to solve these problems, firstly, specialized testing equipment is installed on a truss device, aligning the axis of the specialized testing equipment with the axis of the drainage inspection well, and restricting the movement direction of the specialized testing equipment to the vertical direction to ensure stability during the lowering process; secondly, detection components are used to detect defects around the drainage inspection well, and symmetrically arranged elastic expansion joints ensure the distance between the detection components and the inner wall of the drainage inspection well; finally, the applicability of the truss device is improved by installing multiple specialized testing devices on a single truss device to reduce the replacement time of the specialized testing equipment, thereby shortening the inspection time of the drainage inspection well.

[0098] Based on the above-mentioned inventive discovery, the technical solution of this application is proposed.

[0099] The following describes the application scenarios of the truss device provided in this application.

[0100] Figure 1 This is a schematic diagram of a truss device provided in an embodiment of this application. It should be noted that... Figure 1 The examples shown are merely examples of scenarios in which this application can be applied, to help those skilled in the art understand the technical content of this application, but do not mean that this application cannot be used in other devices, systems, environments or scenarios.

[0101] like Figure 1 As shown, this is an application scenario for the truss device, which includes: a drainage inspection well 100 and a truss device 200.

[0102] The truss device 200 is installed in the installation area near the opening of the drainage inspection well 100, and the truss device 200 is used for the inspection of the drainage inspection well 100.

[0103] The truss device 200 includes two uprights 300, a crossbeam 400, a rod assembly 500, and a dedicated testing device 600. The two ends of the crossbeam 400 are respectively mounted on the two uprights 300, and one end of the rod assembly 500 is mounted on the crossbeam 400. The two uprights 300 are symmetrical along the plane containing the axis of the drainage inspection well 100, and the axis of the rod assembly 500 coincides with the axis of the drainage inspection well 100. The dedicated testing device 600 is mounted on the rod assembly 500, which is used to lower the dedicated testing device 600 to a preset depth in the drainage inspection well 100. The dedicated testing device 600 is used to photograph the well structure and detect defects around the well.

[0104] Figure 2 Schematic diagram of the truss device provided in the embodiments of this application Figure 1 .like Figure 2 As shown, the truss assembly 200 is used for the inspection of drainage inspection wells, and the truss assembly 200 includes:

[0105] Two uprights (300), crossbeams (400), pole sets (500), and specialized testing equipment (600);

[0106] The two ends of the crossbeam 400 are respectively installed on two uprights 300, and the length of the crossbeam 400 is greater than the diameter of the well opening of the drainage inspection well;

[0107] The two uprights 300 are symmetrical about the central section of the crossbeam 400 in the vertical direction, and the crossbeam 400 is used to slide along the two uprights 300 in the vertical direction.

[0108] Specifically, the two uprights 300 are the main supporting structures of the truss assembly 200, used to provide support for the crossbeams 400.

[0109] The length of the crossbeam 400 is greater than the diameter of the drainage inspection well opening, which is equivalent to the distance between the two uprights 300 being greater than the diameter of the drainage inspection well opening. This helps the truss device 200 to cover and adapt to drainage inspection wells of different diameters.

[0110] The central section of the beam 400 in the vertical direction refers to the imaginary section in which the beam 400 is cut into two halves in the vertical direction, and this section is located exactly at the center of the beam 400; the two uprights 300 are symmetrical along this section, which helps to maintain the stability and balance of the truss assembly 200.

[0111] The crossbeam 400 is designed with a sliding mechanism, which allows it to slide vertically along the two uprights 300. This sliding motion can be achieved through structures such as toothed rail and gear structure, guide rail and slider structure, slide groove and slide rail structure or wheel sliding structure, as well as drive methods such as motor drive, hydraulic drive, pneumatic drive or manual drive. This helps to adjust the height of the truss device 200 to accommodate truss devices 200 of different depths.

[0112] The lever assembly 500 includes: a fixed lever 510 and a sliding lever 520;

[0113] The first end of the fixed rod 510 is mounted on the crossbeam 400. The fixed rod 510 is used to slide along the crossbeam 400 in the horizontal direction, and the sliding rod 520 is used to slide along the fixed rod 510 in the vertical direction.

[0114] The special inspection equipment 600 is installed on the sliding rod 520. The crossbeam 400 and the sliding rod 520 are used together to lower the special inspection equipment 600 to the preset depth of the drainage inspection well. The special inspection equipment 600 is used to take pictures of the well structure and detect defects around the well.

[0115] Specifically, both the fixed rod 510 and the sliding rod 520 are designed with sliding mechanisms. The former allows the fixed rod 510 to slide horizontally along the crossbeam 400. This sliding motion can be achieved through structures such as linear guide rails and sliders, grooves and rollers, sliding bearings and shafts, magnetic levitation, or chain and belt drives, as well as the aforementioned driving methods. This facilitates the horizontal movement of the dedicated testing equipment 600 to cover different areas of the drainage inspection well 100. The latter allows the sliding rod 520 to slide vertically along the fixed rod 510. This sliding motion can be achieved through structures such as sleeves and sliding grooves, threaded adjustment structures, hydraulic cylinder drives, or pneumatic cylinder drives, as well as the aforementioned driving methods. This facilitates the vertical movement of the dedicated testing equipment 600 to adjust its depth position.

[0116] It is important to note that Figure 2 In the middle, the sliding rod 520 is sleeved on the fixed rod 510, so the fixed rod 510 is not visible.

[0117] Furthermore, the crossbeam 400 and the sliding rod 520 work together. When the depth of the specialized inspection equipment 600 needs to be adjusted, the height of the crossbeam 400 is first adjusted for approximate positioning, and then the sliding rod 520 is slid along the fixed rod 510 for finer adjustments. This helps the specialized inspection equipment 600 to be accurately lowered to the preset depth of the drainage inspection well. The preset depth is set by technicians based on the specific conditions of the drainage inspection well and the inspection requirements. Once the specialized inspection equipment 600 reaches the preset depth, it can perform tasks such as photographing the well structure and detecting defects around the well.

Figures 3 to 5 As shown, the dedicated detection device 600 is any one of the water jet assembly 610, the panoramic quantization assembly 620, and multiple detection assemblies 630;

[0119] The water jet assembly 610 includes: a rotary joint 611 rotatably mounted on a sliding rod 520, and a water jet nozzle 612 mounted on the rotary joint 611; the water jet nozzle 612 is used to clean the drainage inspection well.

[0120] The panoramic quantization component 620 includes: a rotary joint 611, and a sensing element 621 mounted on the rotary joint 611; the sensing element 621 is used to capture images of the well structure of the drainage inspection well.

[0121] Each detection component 630 includes: an elastic telescopic member 631 mounted on the sliding rod 520, and a detection element 632 mounted on the elastic telescopic member 631; the detection element 632 is used to detect defects around the drainage inspection well.

[0122] The sliding rod 520 is used to lower the water jet assembly 610, the panoramic quantization assembly 620, or multiple detection assemblies 630 to a preset depth in the drainage inspection well.

[0123] Specifically, the dedicated testing equipment 600 is specifically designed for the inspection of drainage inspection wells. It can select any one of the following components: water jet assembly 610, panoramic quantization assembly 620, or multiple detection assemblies 630, depending on the specific inspection requirements. This modular design allows the dedicated testing equipment 600 to flexibly handle different operational tasks, improving inspection efficiency and accuracy.

[0124] It is important to note that Figure 2 In this example, the dedicated testing equipment 600 is the water jet assembly 610.

[0125] like Figure 3 As shown, the water jet assembly 610 is specifically designed for cleaning drainage inspection wells. The rotary joint 611 is the component that enables the water jet nozzle 612 to rotate, allowing it to rotate freely in the horizontal or vertical direction, thus enabling the cleaning of every corner of the drainage inspection well. The water jet nozzle 612 cleans the drainage inspection well with high-pressure water flow. The nozzle design typically takes into account factors such as the water jet angle, pressure, and flow rate to ensure cleaning effectiveness.

[0126] like Figure 4 As shown, the panoramic quantization component 620 is specifically used for capturing images of the well structure of drainage inspection wells. The rotary joint 611 functions in the panoramic quantization component 620 in the same way it does in the water jet component 610, enabling the rotation of some or all of the devices in the sensing element 621. The sensing element 621 can be a wide-angle camera, or at least one of sonar radar and lidar. By capturing images with the sensing element 621, information about the well structure of the drainage inspection well can be obtained, providing data support for subsequent analysis and processing.

[0127] like Figure 5As shown, the detection component 630 is specifically designed for detecting defects around drainage manholes. The elastic telescopic component 631 adjusts the distance between the detection element 632 and the inner wall of the drainage manhole according to its inner diameter, which helps improve the detection accuracy of the detection element 632. The detection element 632 can be at least one of a detection radar, ultrasonic sensor, or infrared sensor. Through the detection of the detection element 632, information on defects around the drainage manhole, such as cracks and corrosion, can be obtained, providing data support for subsequent analysis and processing.

[0128] In other embodiments, the dedicated detection device 600 consists of multiple detection components 630; the multiple detection components 630 are simultaneously mounted on the sliding rod 520 and arranged axially symmetrically along the axis of the sliding rod 520; the sliding rod 520 is also used to lower the multiple detection components 630 to a preset depth in the drainage inspection well.

[0129] Each detection component 630 includes: an elastic telescopic member 631 and a detection element 632; the detection element 632 is mounted on the elastic telescopic member 631, which is used to adaptively adjust according to the inner diameter of the drainage inspection well, and control the distance between the detection element 632 and the inner wall of the drainage inspection well; the detection element 632 is used to detect defects around the drainage inspection well.

[0130] Specifically, such as Figure 5 As shown, the multiple detection components 630 are arranged axially symmetrically along the axis of the sliding rod 520, resulting in the following technical effects:

[0131] First, the axisymmetric arrangement ensures that the detection components 630 are evenly distributed within the drainage inspection well, enabling more comprehensive and thorough defect detection around the well. This arrangement helps reduce missed detections due to blind spots, improving the accuracy and reliability of the detection.

[0132] Secondly, the axisymmetric arrangement helps to balance the weight distribution of the detection component 630 on the sliding rod 520, thereby enhancing the stability of the truss device 200. During the detection process, stable equipment can better resist external interference, such as wind and water flow, ensuring the accuracy and consistency of the detection results.

[0133] Furthermore, since the multiple detection components 630 are arranged symmetrically along the axis of the sliding rod 520, the data they acquire is spatially symmetrical. This symmetry helps simplify the data processing process and improve data processing efficiency; at the same time, the symmetrical data distribution also helps to more easily discover and identify potential defect patterns, providing more valuable reference information for subsequent maintenance and repair.

[0134] Finally, the elastic telescopic component 631 can adaptively adjust according to the inner diameter of the drainage inspection well, controlling the distance between the detection element 632 and the inner wall within a certain range. The axisymmetrically arranged detection assembly 630 can better adapt to changes in different well diameters, ensuring that the distance between each detection element 632 and the inner wall of the drainage inspection well is the same, thus improving the accuracy of detection.

[0135] This application provides a truss device comprising: two uprights, a crossbeam, a rod assembly, and a dedicated testing device; the two ends of the crossbeam are respectively mounted on the two uprights, and the length of the crossbeam is greater than the diameter of the well opening of the drainage inspection well; the two uprights are symmetrical along the central cross-section of the crossbeam in the vertical direction, and the crossbeam is used to slide along the two uprights; the rod assembly includes a fixed rod and a sliding rod; the first end of the fixed rod is mounted on the crossbeam, and the fixed rod is used to slide along the crossbeam, and the sliding rod is used to slide along the fixed rod; the dedicated testing device is mounted on the sliding rod, and the dedicated testing device is used to photograph the well structure and detect defects around the well of the drainage inspection well. The following technical effects were achieved: By sliding the crossbeam along the two uprights, the fixed rod along the crossbeam, and the sliding rod along the fixed rod, stability during the lowering process was ensured, solving the problem of inaccurate detection results for well structure quality and well perimeter defect development; by installing any one of the water jet assembly, panoramic quantization assembly, and multiple detection components on the sliding rod, the specialized detection equipment could flexibly handle different operational tasks, solving the problem of long detection time for well structure quality and well perimeter defect development; the elastic telescopic component adaptively adjusted according to the inner diameter of the drainage inspection well, controlling the distance between the detection components and the inner wall of the drainage inspection well, solving the problem of inaccurate detection results for well perimeter defect development.

[0136] In one possible design, such as Figure 2 As shown, the truss assembly 200 also includes: a hoist motor 700;

[0137] The hoist motor 700 is mounted on the top surface of the crossbeam 400;

[0138] The first end of the fixed rod 510 is installed on the bottom surface of the crossbeam 400. The hoisting rope of the winch motor 700 is connected to the sliding rod 520. The winch motor 700 is used to drive the sliding rod 520 to slide along the fixed rod 510.

[0139] Specifically, the sliding rod 520 slides along the fixed rod 510 through the winch motor 700, which can be achieved through a sleeve and sliding groove structure.

[0140] Figure 6 This is a schematic diagram of the structure of a hoisting motor provided in an embodiment of this application. Figure 6As shown, the hoist motor 700 includes: a motor body 710, a drum 720, a controller 730, and a fixed base 740; a hoisting rope is wound on the drum 720; the controller 730 includes structures such as an electromagnetic brake and a reducer, used to control the lifting or lowering speed of the hoisting rope.

[0141] The technical effect of this application embodiment is that the sliding rod can slide along the fixed rod by means of a winch motor.

[0142] In one possible design, such as Figure 2 As shown, the crossbeam 400 includes: the crossbeam body 410;

[0143] The main body of the crossbeam 410 adopts a ladder-type structure.

[0144] Specifically, the main body of the crossbeam 410 adopts a ladder-type structure that is laid flat. The ladder-type structure means that the main body of the crossbeam 410 is composed of multiple horizontal rods, forming a stable frame. This structure can make more efficient use of space, providing more space for the installation of other equipment and the passage of technicians, thus improving the space utilization rate of the main body of the crossbeam 410.

[0145] The technical effect of this application embodiment is that the space utilization rate of the main body of the crossbeam is improved by using a ladder-type structure.

[0146] In one possible design, such as Figure 2 As shown, the crossbeam 400 also includes: two double-track transverse slides 420, an upper platform 430 and a lower platform 440;

[0147] Two double-track transverse sliding grooves 420 are respectively installed on the top and bottom surfaces of the main body of the crossbeam 410;

[0148] The upper platform 430 and the lower platform 440 are respectively installed on the corresponding double-track transverse slide 420. Both the upper platform 430 and the lower platform 440 are used to slide along the corresponding double-track transverse slide 420.

[0149] Both the upper platform 430 and the lower platform 440 have a first through hole 450 in the vertical direction;

[0150] The hoisting motor 700 is mounted on the upper platform 430, and the first end of the fixing rod 510 is mounted on the lower platform 440. The hoisting rope of the hoisting motor 700 passes through the first through hole 450 of the upper platform 430, the crossbeam body 410 and the first through hole 450 of the lower platform 440 in sequence, and is connected to the sliding rod 520.

[0151] Specifically Figure 7 This is a schematic diagram of the structure of the upper platform provided in an embodiment of this application. Figure 7As shown, the upper platform 430 includes a support member 431 and a support panel 432. The upper platform 430 is installed on a double-track transverse slide groove 420 on the top surface of the main beam 410. The support member 431 of the upper platform 430 is clamped between the double-track transverse slide grooves 420, and the upper platform 430 slides along the double-track transverse slide grooves 420 via the support member 431. The top of the support member 431 is connected to the support panel 432, and the fixed base 740 of the hoist motor 700 is installed and fixed on the support panel 432.

[0152] Align the position of the drum 720 with the opening positions of the two first through holes 450, and place the hoisting rope of the drum 720 below the crossbeam 400 through the two first through holes 450 and the crossbeam body 410, and connect it with the sliding rod 520.

[0153] The technical effects of this application embodiment are as follows: the upper platform and double transverse sliding grooves enable the hoisting motor to slide along the crossbeam; the lower platform and double transverse sliding grooves enable the fixed rod to slide along the crossbeam; and the two first through holes and the crossbeam body enable the connection between the hoisting rope of the hoisting motor and the sliding rod.

[0154] In one possible design, Figure 8 This is a schematic diagram of the structure of the lower support provided in an embodiment of this application. Figure 2 and Figure 8 As shown, the lower platform 440 includes: a hook 441, a clamp 442, and a mounting plate 443;

[0155] The connector 441 is clamped on the double transverse sliding groove 420 on the bottom surface of the main body of the crossbeam 410;

[0156] The clamp 442 is fixedly installed on the hanger 441, and the mounting plate 443 is rotatably installed on the clamp 442;

[0157] Multiple mounting bolts 4431 are provided at the corners of the bottom surface of the mounting plate 443; the first end of the fixing rod 510 is mounted on the mounting plate 443 by multiple mounting bolts 4431.

[0158] Specifically, a lower platform 440 is installed on the double transverse sliding groove 420 on the bottom surface of the main beam 410, and the lower platform 440 slides along the double transverse sliding groove 420 via a hook 441.

[0159] Mounting plate 443 is rotatably mounted on clamping plate 442, which can be achieved by rotating shaft or rotating pin. To reduce friction and wear, bearings can be installed on the contact surfaces of the two, or a sliding surface can be made using lubricating material; if necessary, the rotary connection can be locked by locking nuts, locking plates, or by using friction. The function of the rotary connection is to reduce the installation difficulty of the special testing equipment 600 by appropriately rotating the sliding rod 520 when installing the special testing equipment 600 onto the sliding rod 520.

[0160] The mounting plate 443 is provided with a plurality of mounting bolts 4431. Correspondingly, the fixing rod 510 is provided with a plurality of bolt holes that match the plurality of mounting bolts 4431. The first end of the fixing rod 510 is mounted on the mounting plate 443 through the cooperation between the plurality of mounting bolts 4431 and the plurality of bolt holes.

[0161] The technical effect of this application embodiment is that the first end of the fixing rod is installed on the main body of the crossbeam by means of the lower platform.

[0162] In one possible design, such as Figure 2 As shown, both uprights 300 include: upright body 310, lifting component 320 and lifting device 330;

[0163] The main frame 310 adopts a ladder-type structure;

[0164] On the vertical column 312 of the main body of the support frame 310, a vertical sliding groove 311 is provided on the side near the pole group 500; the vertical sliding groove 311 is flush with the vertical column 312 of the support frame.

[0165] The lifting component 320 is installed on the vertical slide groove 311, and the lifting device 330 is used to drive the lifting component 320 to slide along the vertical slide groove 311;

[0166] One end of the crossbeam 400 is installed on the top of the lifting component 320.

[0167] Specifically, the two uprights 300 have the same structure. Here, we will describe the structure of one of the uprights 300 in detail.

[0168] The main frame 310 adopts a ladder-type structure, similar to the aforementioned main beam 410, which improves the space utilization of the main frame 310. The opening of the vertical slide 311 faces the drainage inspection well. The T-shaped structure on the back of the lifting component 320 matches the opening of the vertical slide 311. Driven by the lifting device 330, the lifting component 320 slides along the vertical slide 311, thereby driving the crossbeam 400 to slide on the two main frames 300. At the same time, the vertical slide 311 is flush with the vertical column 312 of the main frame, allowing the lifting component 320 to slide to the top or bottom of the vertical column 312 of the main frame; correspondingly, one end of the crossbeam 400 is installed at the top of the lifting component 320 to maximize the sliding stroke of the crossbeam 400.

[0169] The technical effect of this application embodiment is that the sliding of the crossbeam along the two uprights is achieved through the lifting component and the lifting device.

[0170] In one possible design, the lifting component 320 is provided with a linear toothed rail 321;

[0171] The lifting device 330 includes a drive motor 331, the output shaft of which is configured as a first gear shaft 3311; the tooth profile of the first gear shaft 3311 of the drive motor 331 matches the tooth profile of the linear gear rail 321.

[0172] Specifically, the lifting component 320 has a linear toothed rail 321 on its front side. When the drive motor 331 outputs power, the first gear shaft 3311 rotates, causing the lifting component 320 to slide on the vertical slide groove 311.

[0173] The technical effect of this application embodiment is that the lifting component slides along two vertical grooves through the first gear shaft.

[0174] In one possible design, both uprights 300 include: a tray 322;

[0175] The pallet 322 is installed on the horizontal column 313 of the upright body 310, and the lifter 330 is installed on the pallet 322;

[0176] The first gear shaft 3311 is flush with the middle position of the vertical slide groove 311.

[0177] Specifically, a horizontal column 313 is installed at a certain position on the vertical column 312 of the support frame. A support plate 322 is installed on the horizontal column 313, and the electrical box 332 and drive motor 331 of the lifting device 330 are both installed on the support plate. Through the support plate 322, the first gear shaft 3311 is aligned with the middle position of the vertical slide 311, that is, it is located at the middle position in the height direction of the vertical slide 311. At the same time, the length of the lifting component 320 is approximately half the length of the vertical slide 311. The reason is that if the length of the lifting component 320 is too small or too large, it will limit the sliding stroke of the crossbeam 400.

[0178] The technical effect of this application embodiment is that the sliding stroke of the crossbeam is increased by the positional relationship between the first gear shaft and the vertical slide groove, and the length relationship between the lifting member and the vertical slide groove.

[0179] In one possible design, both uprights 300 include: a base 340;

[0180] The main frame 310 is vertically mounted on the base 340;

[0181] A diagonal bracing support frame 350 is provided at the connection between the main body 310 and the base 340;

[0182] A rib plate 360 ​​is provided at the connection between the crossbeam 400 and the lifting component 320.

[0183] Specifically, the line connecting the centers of the two bases 340 and the plane formed by the two main support bodies 310 both pass through the center of the drainage inspection well opening, so that the axis of the crossbeam 400 coincides with the axis of the drainage inspection well. In addition, the diagonal bracing frame 350 and the rib plate 360 ​​are used to improve the connection stability of the truss device 200.

[0184] In one possible design, Figure 9 A schematic diagram of the structure of the base provided in the embodiments of this application. Figure 1 ; Figure 10 A schematic diagram of the structure of the base provided in the embodiments of this application. Figure 2 ; Figure 11 This is a schematic diagram of the roller provided in an embodiment of this application. Figures 9 to 11 As shown, the base 340 includes: an upper base plate 341, a lower base plate 342, and a jack 343;

[0185] A second through hole 344 is provided at the center of both the upper base plate 341 and the lower base plate 342;

[0186] The base of the jack 343 abuts against the horizontal column 313 of the main body of the frame 310. The top rod of the jack 343 is coaxially aligned with the two second through holes 344. The jack 343 is used to lift the truss device 200.

[0187] The bottom plate 342 has multiple anchor bolt holes 345 and multiple roller bolt holes 346.

[0188] When the truss assembly 200 is lifted by the jack 343, each roller bolt hole 346 is used to install or remove the roller 347, which is used to move the truss assembly 200.

[0189] Specifically, jack 343 penetrates the upper base plate 341, and the base of jack 343 abuts against the horizontal column 313 of the upright frame. The top rod of jack 343 can retract to between the upper base plate 341 and the lower base plate 342, at which time the truss device 200 is fixed; the top rod of jack 343 can also extend out of the lower base plate 342, at which time the truss device 200 is lifted.

[0190] Furthermore, when the truss assembly 200 is fixed, the truss assembly 200 can be reinforced through the anchor bolt holes 345 and the matching anchor bolts.

[0191] The roller bolt hole 346 penetrates the lower base plate 342, and the jack 343 and roller 347 enable the overall movement of the truss device 200. When moving the truss device 200, firstly, the truss device 200 is lifted as a whole using the jack 343, and the roller 347 is installed on the roller bolt hole 346; secondly, the jack 343 is retracted, and the roller 347 contacts the ground; finally, the truss device 200 is quickly moved as a whole using the roller 347 to facilitate continuous inspection of multiple drainage manholes. The steps for fixing the truss device 200 are similar to those for moving the truss device 200, and will not be repeated in this embodiment.

[0192] The technical effect of this application embodiment is that the overall movement of the truss device is achieved by using jacks and rollers.

[0193] In one possible design, a feasible structure for a lever assembly 500 is provided. Figure 12 This is a schematic diagram of the structure of the fixing rod provided in an embodiment of this application; Figure 13 This is a schematic diagram of the structure of the first sliding rod provided in an embodiment of this application; Figure 14 This is a schematic diagram of the structure of the second sliding rod provided in an embodiment of this application. Figures 12 to 14 As shown, the sliding rod 520 includes: a first sliding rod 530 and a second sliding rod 540;

[0194] The fixed rod 510 is sleeved on the first sliding rod 530, and the first sliding rod 530 is used to slide along the fixed rod 510 in the vertical direction;

[0195] The second sliding rod 540 is sleeved on the fixed rod 510, and the second sliding rod 540 is used to slide along the fixed rod 510 or the first sliding rod 530 in the vertical direction.

[0196] Rotary joint 611 or multiple elastic telescopic components 631 are all mounted on the second sliding rod 540.

[0197] Specifically, the fixed rod 510 is sleeved on the first sliding rod 530, which is equivalent to the inner column and the fixed rod 510 is equivalent to the middle column; the second sliding rod 540 is sleeved on the fixed rod 510, which is equivalent to the outer column.

[0198] When the special testing equipment 600 is not lowered, the three are nested together, and the length of the rod group 500 is the shortest. When the special testing equipment 600 is lowered to the lowest position, the first end of the first sliding rod 530 is flush with the second end of the fixed rod 510, the first end of the second sliding rod 540 is flush with the second end of the first sliding rod 530, the fixed rod 510 and the second sliding rod 540 are located at the two ends of the first sliding rod 530 respectively, and the length of the rod group 500 is the longest.

[0199] The technical effect of this application embodiment is that the deployment of the dedicated testing equipment is achieved through the first sliding rod and the second sliding rod.

[0200] In one possible design, the fixed rod 510, the first sliding rod 530, and the second sliding rod 540 are all hollow rectangular shell structures;

[0201] At the middle position of each side of the fixing rod 510, a first slot 511 is provided, which extends through the fixing rod 510 along its length.

[0202] The outer wall dimensions of the first sliding rod 530 match the inner wall dimensions of the fixed rod 510; at the middle position of the outer wall of the two opposite sides of the first sliding rod 530, a strip block 531 matching the first slot 511 is provided; the strip block 531 of the first sliding rod 530 is used to slide along the fixed rod 510 through the two first slots 511.

[0203] At the midpoint of the other two opposite sides of the first sliding rod 530, a second slot 532 is provided along the length direction of the first sliding rod 530 but does not penetrate the first sliding rod 530; the width of the second slot 532 is equal to the width of the first slot 511.

[0204] The inner wall dimension of the second sliding rod 540 matches the outer wall dimension of the fixed rod 510; a tension member is provided at the middle position of the inner wall of the two opposite sides of the second sliding rod 540; the thickness of the tension member is less than the width of the first slot 511; the second sliding rod 540 is used to slide along the fixed rod 510 through the two first slots 511, and slide along the first sliding rod 530 through the two second slots 532.

[0205] Specifically, in the fixed rod 510, both ends of the first slot 511 are flush with both ends of the fixed rod 510. In the first sliding rod 530, both ends of the strip block 531 are flush with both ends of the first sliding rod 530. The first slot 511 and the strip block 531 form a groove and rail structure, enabling the first sliding rod 530 to slide along the fixed rod 510. The first end of the second slot 532 is flush with the first end of the first sliding rod 530, and the second end of the second slot 532 is separated from the second end of the first sliding rod 530 by a certain distance. In the second sliding rod 540, the length of the pulling member is less than the length of the first slot 511 and the second slot 532. The pulling member and the first slot 511 form a groove and rail structure, enabling the second sliding rod 540 to slide along the fixed rod 510. The pulling member and the second slot 532 form a groove and rail structure, enabling the second sliding rod 540 to slide along the first sliding rod 530.

[0206] Furthermore, when the second sliding rod 540 slides along the first sliding rod 530, the second sliding rod 540 is in contact with the strip block 531 of the first sliding rod 530, and the second sliding rod 540 will not rotate or loosen.

[0207] The technical effect of this application embodiment is that the relative sliding between the fixed rod, the first sliding rod, and the second sliding rod is achieved through the seam, the strip block, and the tension member.

[0208] In one possible design, Figure 15 This is a schematic diagram of the structure of the symmetrical component provided in an embodiment of this application. Figure 14 and Figure 15 As shown, the second sliding rod 540 is composed of two symmetrical pieces 541 joined together;

[0209] A tensioning member 542 is provided at the middle position of the inner wall of the symmetrical member 541;

[0210] The first end of the symmetrical member 541 is symmetrically provided with multiple splicing plates 543. The two symmetrical members 541 are used to splice the multiple splicing plates 543 to form the second sliding rod 540.

[0211] Specifically, the two symmetrical components 541 have the same structure. Here, the structure of one of the symmetrical components 541 will be described in detail.

[0212] The aforementioned tensioning member 542 is located at the center of the inner wall of the complete side of the symmetrical member 541. An even number of splicing plates 543 are symmetrically arranged on the first half of the symmetrical member 541; for example, there can be two splicing plates 543. Each splicing plate 543 has a pre-set bolt hole. The two symmetrical members 541 are spliced ​​together to form the second sliding rod 540 through the aforementioned multiple splicing plates 543 and mounting bolts that match the pre-set bolt holes.

[0213] The technical effect of this application embodiment is that a second sliding rod is obtained by assembling two symmetrical parts, providing a method for installing a rod assembly.

[0214] In one possible design, such as Figures 12 to 15 As shown, the second end of the fixed rod 510 is provided with an inner socket 512, and the first end of the first sliding rod 530 is provided with a hanging plate 533. The inner socket 512 is used to limit the hanging plate 533.

[0215] A baffle 544 is provided at the second end of the second sliding rod 540, which is used to limit the second end of the first sliding rod 530.

[0216] Specifically, the inner wall dimension of the fixing rod 510 is greater than or equal to the dimension of the hanging plate 533, the dimension of the hanging plate 533 is greater than or equal to the dimension of the inner socket 512, and the dimension of the inner socket 512 is greater than or equal to the outer wall dimension of the first sliding rod 530. Through the above-mentioned dimensional restrictions, the inner socket 512 can limit the hanging plate 533.

[0217] A baffle 544 is provided at the second end of the second sliding rod 540. Specifically, a baffle 544 is provided on the inner wall of the complete side of the second end of the aforementioned symmetrical member 541. The gap between the two baffles 544 is smaller than the outer wall dimension of the first sliding rod 530. Through the above-mentioned dimensional limitation, the baffle 544 can limit the second end of the first sliding rod 530.

[0218] The technical effect of this application embodiment is that the inner bearing prevents the first sliding rod from falling off the fixed rod; and the baffle prevents the first sliding rod from falling off the second sliding rod.

[0219] In one possible design, it also includes: a hoist motor 700;

[0220] The hoisting motor 700 is installed on the top surface of the crossbeam 400, and the first end of the fixing rod 510 is installed on the bottom surface of the crossbeam 400.

[0221] Each traction member 542 is provided with a traction hole 5421. The hoisting rope of the winch motor 700 is connected to multiple traction holes 5421 at the same time. The winch motor 700 is used to drive the second sliding rod 540 to slide along the fixed rod 510 and the first sliding rod 530 through multiple traction holes 5421.

[0222] Specifically, the hoisting rope of the winch motor 700 is tied to two symmetrically arranged traction holes 5421. The winch motor 700 raises or lowers the second sliding rod 540 through the traction holes 5421, realizing the sliding between the fixed rod 510, the first sliding rod 530 and the second sliding rod 540.

[0223] In one possible design, the crossbeam 400 includes: a lower platform 440;

[0224] The lower base 440 is provided with multiple mounting bolts 4431;

[0225] The first end of the fixed rod 510 is provided with a first mating plate 513, and the first end of the second sliding rod 540 is provided with a second mating plate 545; both the first mating plate 513 and the second mating plate 545 are provided with multiple bolt holes 550 that match the multiple mounting bolts 4431.

[0226] Specifically, the first end of the fixed rod 510 is mounted on the lower platform 440 via the first docking plate 513; the first end of the second sliding rod 540 is also mounted on the lower platform 440 via the second docking plate 545; wherein the first docking plate 513 is sandwiched between the lower platform 440 and the second docking plate 545.

[0227] The technical effect of this application embodiment is that when the special testing equipment is not lowered, the fixed rod, the first sliding rod and the second sliding rod are sleeved through the first docking plate and the second docking plate; when the special testing equipment is lowered, the second docking plate is detached from the lower platform, realizing the sliding between the fixed rod, the first sliding rod and the second sliding rod.

[0228] In one possible design, Figure 16 A schematic diagram of the structure of the rotary joint provided in the embodiments of this application. Figure 1 ; Figure 17 A schematic diagram of the structure of the rotary joint provided in the embodiments of this application. Figure 2 .like Figure 3 , Figure 4 , Figure 14 , Figure 16 and Figure 17 As shown, the second end of the second sliding rod 540 is provided with a fitting hole 546 and a through hole 547;

[0229] The rotary joint 611 includes: a fixed part 6111, a rotating part 6112, and a rotary motor 6113;

[0230] The fastener 6111 has a mounting hole 641 that matches the fitting hole 546 and a pipeline hole 642 that matches the through hole 547; the fastener 6111 is used to be installed at the second end of the second sliding rod 540 through the fitting hole 546 and the through hole 547.

[0231] The rotating component 6112 is rotatably mounted on the fixed component 6111, and the rotating component 6112 is provided with a circumferential toothed track 651.

[0232] The rotary motor 6113 is mounted on the second sliding rod 540, and the output shaft of the rotary motor 6113 is set as the second gear shaft 661; the tooth profile of the second gear shaft 661 of the rotary motor 6113 matches the tooth profile of the circumferential gear rail 651.

[0233] Specifically, the second end of the second sliding rod 540, specifically the complete side surface of the second end of the aforementioned symmetrical member 541, has a fitting hole 546; the half side surface of the second end of the aforementioned symmetrical member 541 has two semi-circular holes symmetrically opened, and the two semi-circular holes connected on the second sliding rod 540 are assembled to form a through hole 547.

[0234] The fastener 6111 includes a mounting end 643 and an inner column end 644. The mounting end 643 has a mounting hole 641 and a pipeline hole 642. The inner wall dimension of the mounting end 643 matches the outer wall dimension of the second sliding rod 540. After the inner column end 644 is installed at the second end of the second sliding rod 540, the mounting hole 641 is aligned with the fitting hole 546, and the pipeline hole 642 is aligned with the through hole 547. The technical effect is that the fastener is installed at the second end of the second sliding rod through the fitting hole and the through hole.

[0235] The inner column end 644 is fixedly mounted on the mounting end 643, and the rotating part 6112 is sleeved on the outside of the inner column end 644 through the roller bearing 652. Under the action of the roller bearing 652, the rotating part 6112 can rotate around the inner column end 644, that is, the fixed part 6111.

[0236] A rotary motor 6113 is installed at a certain position on the second end of the second sliding rod 540. The second gear shaft 661 of the rotary motor 6113 meshes with the circumferential gear track 651 of the rotating component 6112. The technical effect is that the rotary motor drives the rotating component to rotate around the fixed component through the second gear shaft, thereby driving the water jet assembly to rotate.

[0237] In one possible design, the rotary joint 611 also includes a lead wire bracket 645 mounted on the fixture 6111;

[0238] The water jet assembly 610 also includes: a lighting strip and a water supply slip ring; the water jet nozzle 612 and the lighting strip are mounted on the rotating part 6112, and the water supply slip ring is mounted on the lead wire bracket 645;

[0239] The sensing element 621 includes a wide-angle camera and a sonar radar and / or lidar; the panoramic quantization component 620 also includes an illumination strip; the wide-angle camera is mounted on the lead bracket 645, and the sonar radar and / or lidar is mounted on the rotating component 6112.

[0240] Specifically, the lead wire bracket 645 is installed on the inner post end 644 of the fixing member 6111.

[0241] The water jet nozzle 612 is mounted on the rotating component 6112, specifically at its bottom end. The water jet nozzle 612 has a cylindrical shell structure and is equipped with nozzles for spraying high-pressure water. In addition, the water jet assembly 610 also includes an illumination strip and a water supply slip ring. The illumination strip of the water jet nozzle 612 is mounted on the rotating component 6112, specifically on its outer surface; this illumination strip is used for lighting and for technicians to position the water jet nozzle 612. The water supply slip ring is mounted on the lead wire bracket 645, specifically at the center of the rotating working surface of the water jet nozzle 612; the water supply slip ring connects the rotating water jet nozzle 612 to the water supply pipeline, ensuring normal operation of the water jet nozzle 612 during rotation.

[0242] The wide-angle camera can be a fisheye camera, a panoramic camera, or an ultra-wide-angle camera, etc., and it is directly mounted on the lead wire bracket 645 and does not rotate with the rotating component 6112. The illumination strip of the panoramic quantization component 620 is mounted on the rotating component 6112, specifically on the outer surface of the sensing element 621; the illumination strip is used for illumination to facilitate the imaging of the sensing element 621.

[0243] The technical effect of this application embodiment is that it provides a method for connecting a dedicated testing device and a pole assembly, which is convenient and quick to operate and realizes the efficient application of the pole assembly.

[0244] Furthermore, the rod assembly 500, water jet assembly 610, panoramic quantization assembly 620, and detection assembly 630 can all identify the detection depth and orientation to ensure accurate matching and positioning of the detection results.

[0245] Figure 18 This is a schematic flowchart illustrating the drainage inspection well detection method provided in an embodiment of this application. Figures 1 to 18 As shown in the embodiments of this application, a method for detecting drainage inspection wells is also provided. This method is applied to the truss device in the above embodiments. The truss device includes two uprights, a crossbeam, a rod assembly, and a dedicated detection device. The dedicated detection device is any one of a water jet assembly, a panoramic quantization assembly, and multiple detection assemblies. The method includes:

[0246] S101. Install two uprights, crossbeams, and pole assemblies, ensuring that the axis of the pole assembly is collinear with the axis of the drainage inspection well.

[0247] Specifically, the installation of two uprights 300, a crossbeam 400, and a pole assembly 500 includes the following steps:

[0248] S1011. Install the support frame 300. Clean the ground around the drainage inspection well 100, measure and determine the installation position of the truss device 200, and demarcate the installation area. Specifically, this includes: First, installing one side of the support frame 300, including: installing the base 340 of the support frame 300 and fixing it to the ground; installing the vertical column 312 and the horizontal column 313 of the support frame on the base 340, wherein the vertical column 312 is perpendicular to the base 340, and the plane formed by the two vertical columns 312 passes through the center of the drainage inspection well 100; installing the lifting component 320 on the vertical groove 311 of the vertical column 312; installing the lifting device 330 on one of the horizontal columns 313 of the support frame, and engaging the first gear shaft 3311 of the lifting device 330 with the linear gear rail 321 of the lifting component 320. Second, repeat the above operations to complete the installation of the other side of the support frame 300.

[0249] S1012. Install the crossbeam 400. Specifically, this includes: First, activating the lifting device 330, which lowers the lifting component 320 through gear engagement, bringing both lifting components 320 to the same height. Second, installing the crossbeam body 410 at the top of both lifting components 320. Third, installing double transverse sliding grooves 420 sequentially on the top and bottom surfaces of the crossbeam body 410. Finally, installing an upper platform 430 on the double transverse sliding grooves 420 on the top surface of the crossbeam body 410, and installing a lower platform 440 on the double transverse sliding grooves 420 on the bottom surface of the crossbeam body 410.

[0250] S1013. Install the winch motor 700. Adjust the crossbeam 400 to a suitable height and install the winch motor 700 on the upper platform 430.

[0251] S1014. Install the rod assembly 500. Specifically, this includes: First, aligning the strip block 531 of the first sliding rod 530 with the first seam 511 of the fixed rod 510, and fitting the fixed rod 510 onto the first sliding rod 530. Second, assembling the two symmetrical pieces 541 onto the fixed rod 510, allowing the pulling member 542 to pass through the first seam 511 of the fixed rod 510 and the second seam 532 of the first sliding rod 530, and assembling the two symmetrical pieces 541 into a complete second sliding rod 540 using the splicing plate 543. Finally, binding the hoisting rope of the winch motor 700 to the pulling hole 5421 of the pulling member 542, and bolting the fixed rod 510 and the second sliding rod 540 onto the lower platform 440 using the first connecting plate 513 and the second connecting plate 545.

[0252] Furthermore, Figure 19 This is a schematic diagram of the structure of a drainage inspection well during the inspection preparation stage, as provided in an embodiment of this application. Figure 19 As shown, the drainage inspection wells in the preparation phase of the inspection include:

[0253] Annular airbags 130 are installed at the tail end of the upstream pipe section 110 and the beginning end of the downstream pipe section 120 of the drainage inspection well 100. After inflation, the annular airbags 130 form a seal against the inner wall of the pipe. The two annular airbags 130 are connected by a flow guide hose 140, and the water in the upstream pipe section 110 flows to the downstream pipe section 120 through the flow guide hose 140.

[0254] S102. Install the water jet assembly on the rod assembly, adjust the depth of the water jet assembly in the drainage inspection well through the rod assembly, and clean the drainage inspection well through the water jet assembly.

[0255] Specifically, installing the water jet assembly 610 includes the following steps:

[0256] S1021. Install the rotary joint 611 at the second end of the second sliding rod 540.

[0257] S1022. A rotary motor 6113 is installed on the second sliding rod 540, so that the second gear shaft 661 of the rotary motor 6113 meshes with the circumferential toothed track 651 of the rotating part 6112.

[0258] S1023. Install the water jet nozzle 612 on the rotating part 6112.

[0259] The drainage inspection well 100 is cleaned using the water jet assembly 610, including the following steps:

[0260] S1024. Adjust the upper platform 430 and lower platform 440 on the crossbeam 400 to a suitable position to restrict the rotation of the mounting plate 443 relative to the clamping plate 442.

[0261] S1025. Adjusting the bolts disengages the second sliding rod 540 from the lower platform 440, while keeping the fixing rod 510 fixed to the bottom of the lower platform 440. Due to the gravity of the second sliding rod 540 and the water jet assembly 610, the hoisting rope of the winch motor 700 is taut.

[0262] S1026. Start the hoist motor 700 to gradually lower the second sliding rod 540 and the water jet assembly 610. During the lowering process, the first sliding rod 530 also moves down due to gravity until its mounting plate 533 is engaged with the inner bearing 512 of the fixed rod 510, at which point the first sliding rod 530 stops moving down. Continue lowering the second sliding rod 540 and the water jet assembly 610. At this time, the second sliding rod 540 is sleeved on the first sliding rod 530 and fits against the strip block 531 of the first sliding rod 530. The second sliding rod 540 will not rotate or loosen.

[0263] S1027. After lowering the water jet assembly 610 to a suitable position at the bottom of the well, turn on the lighting strip to check the condition of the well wall and activate the water jet nozzle 612. Under the operation of the rotary motor 6113, the water jet nozzle 612 rotates with the rotating part 6112 to complete the deep cleaning of the well wall at the same depth position.

[0264] S1028. Using the winch motor 700, the second sliding rod 540 and the water jet assembly 610 are gradually lifted, and the lifting speed is controlled within a reasonable range to complete the fine cleaning of the inner wall of the drainage inspection well 100 from bottom to top. After being lifted to a certain height, the baffle 544 of the second sliding rod 540 causes the first sliding rod 530 to retract back into the fixed rod 510.

[0265] S1029. After the inner wall of the drainage inspection well 100 is cleaned, the second sliding rod 540 and the water jet assembly 610 are raised above the wellhead of the drainage inspection well 100. The second docking plate 545 is installed on the lower platform 440, and the wastewater generated during cleaning is pumped to the ground surface for centralized treatment.

[0266] S103. Install the panoramic quantization component on the pole assembly, adjust the depth of the panoramic quantization component in the drainage inspection well through the pole assembly, and take pictures of the well structure through the panoramic quantization component.

[0267] Specifically, the panoramic quantization component 620 is installed, and the well structure of the drainage inspection well 100 is photographed using the panoramic quantization component 620, including the following steps:

[0268] S1031. Disassemble the water jet assembly 610 and install the panoramic quantization assembly 620 at the second end of the second sliding rod 540.

[0269] S1032. Restart the hoist motor 700, and gradually lower the second sliding rod 540 and the panoramic quantization component 620 to a suitable position at the bottom of the well. Then, activate the sensing element 621, and the wide-angle camera begins to capture high-definition images of the well structure. Under the operation of the rotary motor 6113, the sensing element 621 rotates with the rotating component 6112, driving the sonar radar and / or lidar to rotate and operate. The high-definition images captured by the wide-angle camera and the data collected by the sonar radar and / or lidar are processed to generate a panoramic unfolded view of the inner wall of the drainage inspection well 100, enabling refined detection of dimensional parameters at various height positions of the inspection well, as well as defects such as deformation, corrosion, and cracks.

[0270] S1033. Gradually raise the second sliding rod 540 and the panoramic quantization component 620 until the inspection is completed. The lowering and raising of the panoramic quantization component 620 is similar to the lowering and raising of the water jet component 610, and will not be described again in this embodiment.

[0271] S104. Install multiple detection components on the rod assembly, adjust the depth of the multiple detection components in the drainage inspection well through the rod assembly, and perform well perimeter defect detection through the multiple detection components.

[0272] The installation, lowering, and lifting of the detection component 630 are similar to those of the water jet component 610, and will not be described in detail in this embodiment.

[0273] After inspection, the truss device 200 is dismantled step by step according to the installation sequence, or the truss device 200 is moved to other drainage inspection wells, and the area around the well is cleaned up afterward. After all the work tasks are completed, the acquired data on the well structure and the data on defects detected around the well are processed and analyzed to obtain the dimensional parameters of each depth of the drainage inspection well, the material density, defects such as deformation, corrosion and cracks in the well, as well as the water leakage and voids around the well, and to determine the repair and replacement plan for the drainage inspection well.

[0274] The technical advantages of this application are: it eliminates the need for technicians to go down into the well, thus improving the safety of drainage well inspection; it proposes a truss device that is easy to install and disassemble, which can meet the inspection needs of drainage wells of various conventional depths, and is easy to install and occupies little space.

[0275] In one possible design, Figure 20 This is a schematic diagram of the detection component provided in an embodiment of this application. Figure 5 and Figure 20 As shown, each elastic telescopic member 631 includes: a fixed base 6311, an inner support member 6312, and a push-pull member 6313;

[0276] The fixed base 6311 is mounted on the sliding rod 520;

[0277] The inner support member 6312 includes: a traveling track 681, a telescopic support frame 682, and a fixed support frame 683; the first end of the traveling track 681 is mounted on the fixed base 6311 via the telescopic support frame 682, and the second end of the traveling track 681 is mounted on the fixed base 6311 via the fixed support frame 683; the distance between the first end of the traveling track 681 and the crossbeam 400 is less than the distance between the second end of the traveling track 681 and the crossbeam 400;

[0278] The first end of the push-pull member 6313 is mounted on the fixed base 6311, and the second end of the push-pull member 6313 is mounted on the track 681. The second end of the push-pull member 6313 is located between the first end of the track 681 and the second end of the track 681. The push-pull member 6313 is used to drive the track 681 to rotate around the second end of the track 681. The distance between the first end of the push-pull member 6313 and the crossbeam 400 is less than the distance between the second end of the track 681 and the crossbeam 400.

[0279] Specifically, the multiple elastic telescopic components 631 have the same structure. Here, the structure of one of the elastic telescopic components 631 will be described in detail.

[0280] The inner support member 6312 is located at the second end of the fixed rod 510, that is, the end of the fixed rod 510 away from the crossbeam 400. When the detection assembly 630 is lowered, the detection element 632 mounted on the elastic telescopic member 631 is closer to the bottom of the drainage inspection well.

[0281] The main structure of the inner support member 6312 is the track 681. The track 681 is mounted on the fixed base 6311 via a telescopic support frame 682 and a fixed support frame 683, and then on the sliding rod 520. The telescopic support frame 682 is mounted at the first end of the track 681, i.e., the rear end of the track 681; the fixed support frame 683 is mounted at the second end of the track 681, i.e., the front end of the track 681. The telescopic support frame 682 is closer to the crossbeam 400 than the fixed support frame 683.

[0282] When the push-pull member 6313 pushes the traveling track 681, the traveling track 681 rotates around its second end in a direction away from the fixed base 6311, and the telescopic support frame 682 is stretched accordingly. The plane formed by the traveling track 681 increases, making it suitable for well walls with larger diameters. When the push-pull member 6313 pulls the traveling track 681, the traveling track 681 rotates around its second end in a direction closer to the fixed base 6311, and the telescopic support frame 682 is compressed accordingly. The plane formed by the traveling track 681 decreases, making it suitable for well walls with smaller diameters.

[0283] The technical effect of this application embodiment is that by adjusting the size of the plane formed by the traveling track, the distance between the detection element and the inner wall of the drainage inspection well is controlled, thereby improving the accuracy of detection.

[0284] In one possible design, mounting holes 671 are provided at both ends of the fixed base 6311. The mounting holes 671 are used to install the fixed base 6311 on the outer side of the sliding rod 520.

[0285] The fixed base 6311 is also provided with an abutment frame 672;

[0286] The push-pull component 6313 includes: a telescopic cylinder 691, a telescopic spring 692, a connecting plate 693, and a telescopic connecting arm 694;

[0287] The closed end of the telescopic cylinder 691 is installed on the abutment frame 672, the connecting plate 693 is installed on the telescopic rod of the telescopic cylinder 691, and the telescopic spring 692 is sleeved on the telescopic rod;

[0288] The first end of the telescopic connecting arm 694 is mounted on the connecting plate 693, and the second end of the telescopic connecting arm 694 is mounted on the track 681.

[0289] Specifically, the abutment frame 672 is located at the first end of the fixed rod 510, that is, the end of the fixed rod 510 near the crossbeam 400. Therefore, the first end of the fixed rod 510 is equivalent to the abutment end. The closed end of the telescopic cylinder 691 is installed on the abutment frame 672, so the closed end of the telescopic cylinder 691 can remain relatively stationary relative to the fixed rod 510.

[0290] The following are examples of planar changes formed by the traveling tracks 681 provided in the embodiments of this application:

[0291] In the first case, when the connecting plate 693 is actively pulled towards the abutment frame 672, the first end of the telescopic connecting arm 694 moves towards the abutment frame 672, and the traveling track 681 is pulled by the telescopic connecting arm 694, reducing the plane it forms; during this period, the telescopic rod of the telescopic cylinder 691 retracts to the closed end, and the telescopic spring 692 is compressed.

[0292] When the pulling of the connecting plate 693 stops, the telescopic spring 692 resets the connecting plate 693, and the first end of the connecting plate 693 and the telescopic connecting arm 694 moves away from the abutment frame 672, thus resetting the plane they form.

[0293] In the second case, as the travel track 681 retracts and the diameter of the drainage inspection well linearly decreases, the first end of the travel track 681 is pressed back, and the second end of the telescopic connecting arm 694 is also pressed back. The first end of the telescopic connecting arm 694 and the connecting plate 693 then move towards the abutment frame 672. Subsequent details are similar to the first case and will not be repeated in this embodiment.

[0294] In the third case, when the connecting plate 693 is actively pushed away from the abutment frame 672, the first end of the telescopic connecting arm 694 moves away from the abutment frame 672, and the traveling track 681 is pushed by the telescopic connecting arm 694, increasing the plane it forms; during this period, the telescopic rod of the telescopic cylinder 691 extends out of the closed end, and the telescopic spring 692 is stretched.

[0295] When the connecting plate 693 is stopped being pushed, since the two ends of the telescopic spring 692 are not installed on the closed ends of the connecting plate 693 and the telescopic cylinder 691, the telescopic spring 692 cannot reset the connecting plate 693, and the plane formed by the traveling track 681 remains unchanged.

[0296] The technical effect of this application embodiment is that the plane formed by the traveling track can be actively or passively adjusted by the push-pull member 6313.

[0297] In one possible design, the fixed base 6311 is provided with an abutment frame 672, a bracket 673 and a strip hole 674 in sequence, and two pushers 675 are installed on the bracket 673.

[0298] The connecting plate 693 includes: a sliding block 6931, a push plate 6932, two return rods 6933 and a return plate 6934;

[0299] The sliding block 6931 is inserted through the strip hole 674 and is used to slide along the strip hole 674;

[0300] The push plate 6932 is simultaneously installed on the sliding block 6931 and the telescopic rod;

[0301] The first end of each of the two retraction rods 6933 is mounted on the push plate 6932; the second end of each of the two retraction rods 6933 is mounted on the retraction plate 6934; the two retraction rods 6933 and the two pushers 675 are symmetrical along the central section of the telescopic rod in the vertical direction.

[0302] The retraction plate 6934 is mounted on the output shaft of each of the two pushers 675; the two pushers 675 are used to drive the retraction plate 6934 to move toward the abutment frame 672.

[0303] Specifically, the connecting plate 693 moves toward or away from the abutment frame 672 as described in the above embodiment via the sliding block 6931.

[0304] The push plate 6932 is positioned above the sliding block 6931, and a telescopic rod is installed on the push plate 6932 at its center facing the abutment frame 672. The first ends of the two retraction rods 6933 are each installed at the top of the push plate 6932 facing the abutment frame 672; the second ends of the two retraction rods 6933 are each installed on the retraction plate 6934; the two retraction rods 6933 are located on both sides of the telescopic rod and are symmetrical along the central section of the telescopic rod in the vertical direction.

[0305] The retraction plate 6934 is mounted on the same side of two retraction rods 6933, and each of the output shafts of two pushers 675 is mounted thereon. The pushers 675 are fixed to the bracket 673 and can remain relatively stationary relative to the fixed rod 510. When the output shaft of the pusher 675 extends, it drives the retraction plate 6934 to move closer to the abutment frame 672. The retraction plate 6934 then drives the pusher plate 6932 of the connecting plate 693 to maintain the same movement, thus achieving the active pulling of the connecting plate 693 in the first example described above.

[0306] The technical effect of this application embodiment is that the push plate of the connecting plate is actively pulled by the pusher, the return plate and the two return rods; the stability of actively pulling the push plate is improved by the two return rods and the two pushers that are symmetrically arranged.

[0307] In one possible design, such as Figure 19 As shown, as the depth of the drainage inspection well increases, the inner diameter of the drainage inspection well 100 either increases or remains unchanged.

[0308] When the detection component 630 is not lowered into the drainage inspection well 100, the pusher 675 pushes; when the detection component 630 is lowered into the drainage inspection well 100, the pusher 675 retracts.

[0309] Specifically, when the detection component 630 is not lowered into the drainage inspection well 100, since the diameter of the drainage inspection well is generally small, the pusher 675 is activated and the pusher 675 pushes, causing the return plate 6934 to move towards the abutment frame 672, thereby reducing the plane formed by the traveling track 681.

[0310] When the detection component 630 is lowered into the drainage inspection well 100, the pusher 675 is retracted, and the plane formed by the traveling track 681 is enlarged under the action of the telescopic spring 692.

[0311] The technical effect of this application embodiment is that, through the pusher and the telescopic spring, the traveling track is not always parallel to the fixed base, and the attitude can be adaptively adjusted.

[0312] In other embodiments, the telescopic rod of the telescopic cylinder 691 is used to actively push the push plate 6932, thereby realizing the active pushing of the connecting plate 693 in the third case described above.

[0313] In one possible design, both the telescopic support frame 682 and the telescopic connecting arm 694 include: an upper rod 6821, a lower rod 6822, a connecting rod 6823, and a buffer spring 6824.

[0314] The first end of the upper rod 6821 is mounted on the track 681, and the second end of the upper rod 6821 is provided with a cylindrical cavity 6825.

[0315] The first end of the lower rod column 6822 is installed on the fixed base 6311 or the connecting plate 693;

[0316] The first end of the connecting rod 6823 is inserted into the cylindrical cavity 6825, and the second end of the connecting rod 6823 is fixedly connected to the second end of the lower rod 6822.

[0317] The buffer spring 6824 is sleeved on the connecting rod 6823.

[0318] Specifically, the telescopic support frame 682 and the telescopic connecting arm 694 have similar structures. Here, the structure of the telescopic support frame 682 will be described in detail.

[0319] The telescopic support frame 682 includes an upper rod 6821 and a lower rod 6822 respectively installed on the track 681 and the fixed base 6311. The upper rod 6821 has a cylindrical cavity. A connecting rod 6823 is provided between the upper rod 6821 and the lower rod 6822. The first end of the connecting rod 6823 is inserted into the cylindrical cavity 6825, and the second end of the connecting rod 6823 is fixedly connected to the lower rod 6822. A buffer spring 6824 is sleeved on the connecting rod 6823, and the buffer spring 6824 can extend and retract between the upper rod 6821 and the lower rod 6822.

[0320] The technical effect of this application embodiment is that the cylindrical cavity and buffer spring reduce the impact when the track is pushed or pulled, and improve the stability of the detection components.

[0321] In one possible design, the fixed support frame 683, the telescopic support frame 682, and the telescopic connecting arm 694 are all arranged in pairs and are symmetrical about the central section of the traveling track 681 in the vertical direction.

[0322] Specifically, the fixed support frame 683, the telescopic support frame 682, and the telescopic connecting arm 694 are all set in pairs. The technical effect is that the axisymmetric arrangement helps to balance the weight distribution and torque distribution on the track, thereby enhancing the stability of the track.

[0323] The detection component 630 is installed on the detection component 630 through the mounting hole 671. The remaining steps are similar to those for installing the water jet component 610 or the panoramic quantization component 620, and will not be described in detail in this embodiment.

[0324] The detection of defects around the drainage inspection well 100 is performed using the detection component 630, including the following steps:

[0325] S1041. The detection component 630 is lowered to a suitable position at the bottom of the well, and the pusher 675 is retracted, so that the plane formed by the traveling track 681 is increased.

[0326] S1042. Gradually raise the detection component 630 until the inspection is completed. The lowering and raising of the detection component 630 is similar to the lowering and raising of the water jet component 610, and will not be described again in this embodiment.

[0327] In one possible design, the detection element 632 is mounted on the traveling track 681;

[0328] The detection component 632 includes a detection radar assembly.

[0329] In other embodiments, when the telescopic spring 692 resets the connecting plate 693, the plane formed by the traveling track 681 also resets. At this time, the traveling track 681 and the detection element 632 mounted on it are precisely in contact with the wall of the drainage inspection well.

[0330] In other embodiments, the rotation restriction of the mounting plate 443 relative to the clamping plate 442 is removed as needed, the position of the detection component 630 relative to the drainage inspection well is adjusted, and multiple bottom-to-top detections are repeated.

[0331] Specifically, the detection components 630 are arranged in two groups, totaling four. Due to the working principle of each detection radar component, each component can only complete detection within a small arc range, thus covering a limited area of ​​the well wall. The rotatable connection between the mounting plate 443 and the clamping plate 442 allows for multiple detections to be completed after one bottom-up detection by adjusting the orientation, thereby covering a wider area of ​​the well wall.

[0332] In one possible design, an alternative rod assembly structure is provided. This rod assembly differs from the aforementioned rod assembly comprising a fixed rod, a first sliding rod, and a second sliding rod, and is suitable only for the detection assembly, but not for the water jet assembly and the panoramic quantization assembly. Figure 21 Schematic diagram of the truss device provided in the embodiments of this application Figure 2 ; Figure 22 This is a cross-sectional view of the sliding rod provided in an embodiment of this application. Figure 21 and Figure 22 As shown, the truss device 200 also includes: a hoist motor 700;

[0333] The hoisting motor 700 is installed on the top surface of the crossbeam 400, and the first end of the fixing rod 510 is installed on the bottom surface of the crossbeam 400.

[0334] Both the fixed rod 510 and the sliding rod 520 are hollow rectangular shell structures;

[0335] At the middle position of each side of the fixing rod 510, there is a slot 560 that runs along the length of the fixing rod 510 but does not penetrate the fixing rod 510;

[0336] The inner wall dimensions of the sliding rod 520 match the outer wall dimensions of the fixed rod 510, and the length of the sliding rod 520 is less than the length of the slot 560;

[0337] A tension member 542 is provided at the middle of the inner wall of each side of the sliding rod 520. The thickness of the tension member 542 is less than the width of the slot 560.

[0338] Each traction member 542 has a traction hole 5421. The hoisting rope of the winch motor 700 is connected to multiple traction holes 5421 at the same time. The winch motor 700 is used to drive the sliding rod 520 to slide along the fixed rod 510 through multiple traction holes 5421.

[0339] In one possible design, Figure 23 This is a schematic diagram of the structure of the first mounting rod provided in an embodiment of this application; Figure 24 This is a schematic diagram of the structure of the second mounting rod provided in an embodiment of this application; Figure 25 This is a schematic diagram of the sliding rod provided in an embodiment of this application. Figure 8 , Figures 21 to 25 As shown, the crossbeam 400 includes: a lower platform 440;

[0340] The lower base 440 is provided with multiple mounting bolts 4431;

[0341] The fixing rod 510 is formed by splicing the first mounting rod 570 and the second mounting rod 580;

[0342] The second end of the first mounting rod 570 is provided with an inner socket 512, and the first end of the second mounting rod 580 is provided with a splice 581 for splicing with the inner socket 512.

[0343] The first end of the first mounting rod 570 is provided with a first mating plate 513, and the first end of the sliding rod 520 is provided with a second mating plate 545; both the first mating plate 513 and the second mating plate 545 are provided with multiple bolt holes 550 that match the multiple mounting bolts 4431.

[0344] Specifically, the first mounting rod 570 and the slot 560 on the first mounting rod 570 are similar to the fixing rod 510 and the first slot 511 on the fixing rod 510 in the above embodiment, and will not be described again in this embodiment.

[0345] The second mounting rod 580 is similar in shape to the first mounting rod 570, and their inner and outer dimensions are comparable. At the center of each side of the first mounting rod 570, a slot is formed that extends through the first mounting rod 570 along its length. At the center of each side of the second mounting rod 580, a slot is formed that extends along the length of the second mounting rod 580 but does not extend through the first mounting rod 570. When the two are joined together, their respective slots form the slot of the aforementioned fixing rod 510.

[0346] This embodiment includes a rod assembly consisting of a first mounting rod, a second mounting rod, and a sliding rod, which is similar to the rod assembly described above that includes a fixed rod, a first sliding rod, and a second sliding rod. Therefore, this embodiment will not be described in detail again.

[0347] The technical effect of this application embodiment is that it provides another feasible structure for the rod assembly; the sliding rod is limited by the four slots of the second mounting rod and the four tension members of the sliding rod, and ensures that the sliding rod will not rotate or loosen.
