Description

[0002] As an auxiliary facility connecting drainage pipes, drainage inspection wells play an important role in inspecting, cleaning and maintaining drainage pipes. However, due to the influence of the external environment, drainage inspection wells often have defects such as well wall corrosion, structural layer shedding and water leakage. These defects not only affect the normal use of drainage inspection wells, but may also cause safety hazards such as cavities around the wells, ground collapse around the wells and uneven settlement of the well bodies.

[0003] It is particularly important to conduct comprehensive and detailed inspections of various common defects in existing drainage inspection wells. At present, the inspection of drainage inspection wells mainly relies on periscope equipment to obtain images inside the inspection wells, but this method is insufficient in detecting the quality of the well structure and the development of defects around the well.

[0089] It should be noted that the "at..." in this application can be the instant when a certain situation occurs, or a period of time after a certain situation occurs, and this application does not make specific limitations on this. In addition, the truss device provided in this application is only used as an example, and the truss device can also include more or less content.

[0090] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The present application will be described below in conjunction with the accompanying drawings.

[0091] In order to clearly understand the technical solution of the present application, the solution of the prior art is first introduced in detail.

[0092] As an auxiliary facility connecting the drainage pipe, the health of the drainage inspection well is directly related to the operating efficiency and safety of the entire drainage system. It not only provides the necessary entrance for the maintenance of the drainage pipe, but also bears the important responsibility of monitoring the pipeline status and preventing blockage and leakage. However, due to the influence of the external environment, the drainage inspection well often has defects such as well wall corrosion, structural layer shedding and water leakage. Among them, well wall corrosion is mainly caused by the chemical reaction between minerals, acidic substances or alkaline substances in groundwater and well wall materials. This corrosion will gradually weaken the strength of the well wall material. In severe cases, it may even cause well wall perforation, affecting the overall stability of the well body; structural layer shedding is mainly caused by material aging, poor construction quality or long-term uneven force, which not only affects the beauty of the drainage inspection well, but more importantly, it will reduce the bearing capacity of the well body and increase the probability of collapse; water leakage not only wastes water resources, but also may pollute the surrounding environment. In addition, long-term water leakage will accelerate the erosion of the soil around the well and form cavities, 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 wells, ground collapse around the wells, and uneven settlement of the well body.

[0093] It is particularly important to conduct comprehensive and detailed inspections of various defects that are common in existing drainage inspection wells. At present, the inspection of drainage inspection wells mainly relies on periscope equipment to obtain images inside the inspection wells. This method has advantages in identifying blockages and observing the surface conditions inside the wells, but it is insufficient in detecting the quality of the well body structure and the development of defects around the wells, and cannot reflect the true service status of the drainage inspection wells. Therefore, it is necessary to use special inspection equipment such as sensing components and detection components for inspection.

[0094] However, in actual application, there are the following technical problems. The first technical problem is that it is difficult to ensure the stability of the dedicated detection equipment during the lowering process by using a lifting tool to lower it to the preset position of the drainage inspection well, resulting in inaccurate detection results of the wellbore structure quality and the development of defects around the well.

[0095] The second technical problem is that different specialized detection equipment has different working principles and needs to be lowered to the preset position of the drainage inspection well by different lifting tools, which results in a long time spent on the detection of the well body structure quality and the development of defects around the well.

[0096] The third technical problem is that when the special detection equipment is lowered to the preset position of the drainage inspection well by lifting tools, it is difficult to ensure the distance between the detection components of the special detection 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, in response to the above technical problems, it was found in the study that in order to solve these problems, first, the special detection equipment is installed on the truss device so that the axis of the special detection equipment coincides with the axis of the drainage inspection well, and the movement direction of the special detection equipment is limited to the vertical direction to ensure the stability of the special detection equipment during the lowering process; secondly, the drainage inspection well is detected for defects around the well through detection components, and the distance between the detection components and the inner wall of the drainage inspection well is ensured through symmetrically arranged elastic telescopic parts; finally, the applicability of the truss device is improved, and a variety of special detection equipment can be installed through a set of truss devices to reduce the replacement time of the special detection equipment, thereby shortening the detection time of the drainage inspection well.

[0098] Based on the above creative findings, the technical solution of the present application is proposed.

[0099] The following is an introduction to the application scenarios of the truss device provided in this application.

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

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

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

[0103] The truss device 200 includes two vertical frames 300, a crossbeam 400, a rod group 500 and a special detection device 600. The two ends of the crossbeam 400 are respectively mounted on the two vertical frames 300, one end of the rod group 500 is mounted on the crossbeam 400, the two vertical frames 300 are symmetrical along the plane where the axis of the drainage inspection well 100 is located, and the axis of the rod group 500 coincides with the axis of the drainage inspection well 100; the special detection device 600 is mounted on the rod group 500, and the rod group 500 is used to lower the special detection device 600 to the preset depth of the drainage inspection well 100, and the special detection device 600 is used to shoot the well body structure of the drainage inspection well 100 and detect defects around the well.

[0104] Figure 2 A schematic diagram of the structure of the truss device provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the truss device 200 is used for the detection of drainage inspection wells, and the truss device 200 includes:

[0105] Two stands 300, a crossbeam 400, a rod set 500 and a special testing device 600;

[0106] Both ends of the crossbeam 400 are respectively mounted on two vertical frames 300, and the length of the crossbeam 400 is greater than the wellhead diameter of the drainage inspection well;

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

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

[0109] The length of the crossbeam 400 is greater than the diameter of the drainage inspection well, which is equivalent to the distance between the two vertical frames 300 being greater than the diameter of the drainage inspection well, which 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 a section in which the beam 400 is hypothetically 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 plane, which helps to maintain the stability and balance of the truss device 200.

[0111] The crossbeam 400 is designed with a sliding mechanism, allowing it to slide in the vertical direction along the two uprights 300. This sliding movement can be achieved through structures such as a rack and pinion structure, a guide rail and slider structure, a slide groove and slide rail structure or a wheeled sliding structure, as well as driving methods such as motor drive, hydraulic drive, pneumatic drive or human drive, which helps to adjust the height of the truss device 200 to adapt to truss devices 200 of different depths.

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

[0113] The first end of the fixed rod 510 is mounted on the cross beam 400 , the fixed rod 510 is used to slide along the cross beam 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 detection equipment 600 is installed on the sliding rod 520, and the crossbeam 400 and the sliding rod 520 are used together to lower the special detection equipment 600 to the preset depth of the drainage inspection well; the special detection equipment 600 is used to photograph the well body 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 along the crossbeam 400 in the horizontal direction. This sliding motion can be achieved through structures such as a linear guide and a slider structure, a slide groove and a roller structure, a sliding bearing and a shaft structure, a magnetic suspension structure or a chain belt transmission structure, and the above-mentioned driving methods, which helps the special detection device 600 to move in the horizontal direction to cover different areas of the drainage inspection well 100. The latter allows the sliding rod 520 to slide along the fixed rod 510 in the vertical direction. This sliding motion can be achieved through structures such as a sleeve and a sliding groove structure, a threaded adjustment structure, a hydraulic cylinder drive structure or a cylinder drive structure, and the above-mentioned driving methods, which helps the special detection device 600 to move in the vertical direction to adjust its depth position.

[0116] It should be noted that Figure 2 In the embodiment, the sliding rod 520 is sleeved on the fixing rod 510, so the fixing rod 510 is not visible.

[0117] Furthermore, the crossbeam 400 and the sliding rod 520 work together. When the depth of the special detection device 600 needs to be adjusted, the height of the crossbeam 400 is adjusted to roughly position it, and then the sliding rod 520 slides on the fixed rod 510 to make a more precise adjustment, which helps the special detection device 600 to be accurately lowered to the preset depth of the drainage inspection well. Among them, the preset depth is set by the technicians according to the specific conditions and detection requirements of the drainage inspection well. After the special detection device 600 reaches the preset depth, it can perform tasks such as well body structure photography and well periphery defect detection.

Figures 3 to 5 As shown, the dedicated detection device 600 is any one of a water jet component 610, a panoramic quantization component 620, and a plurality of detection components 630;

[0119] The water jet assembly 610 includes: a rotary joint 611 rotatably mounted on the 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 component 621 installed on the rotary joint 611; the sensing component 621 is used to photograph the well body structure of the drainage inspection well;

[0123] Specifically, the dedicated detection device 600 is a detection device dedicated to drainage inspection well detection. It can select any one of the water jet component 610, the panoramic quantization component 620 or multiple detection components 630 according to specific detection requirements. This modular design enables the dedicated detection device 600 to flexibly respond to different work tasks and improve detection efficiency and accuracy.

[0124] It should be noted that Figure 2 In the embodiment, the dedicated detection device 600 is a water jet assembly 610 as an example.

[0125] like Figure 3 As shown, the water jet assembly 610 is specially used for cleaning the drainage inspection well. The rotating joint 611 is a component for realizing the rotation of the water jet nozzle 612, which allows the water jet nozzle 612 to rotate freely in the horizontal or vertical direction, so as to clean every corner of the drainage inspection well; the water jet nozzle 612 cleans the drainage inspection well with high-pressure water flow, and the design of the nozzle usually takes into account factors such as the spray angle, pressure and flow rate of the water flow to ensure the cleaning effect.

[0126] like Figure 4 As shown, the panoramic quantization component 620 is dedicated to photographing the wellbore structure of the drainage inspection well. The role of the rotary joint 611 in the panoramic quantization component 620 is the same as that in the water jet component 610, which realizes the rotation of part or all of the equipment in the sensing component 621; the sensing component 621 can be a wide-angle camera, as well as at least one of a sonar radar and a laser radar, etc. Through the shooting of the sensing component 621, the wellbore structure information 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 used for detecting defects around the drainage inspection well. The elastic expansion member 631 adjusts the distance between the detection component 632 and the inner wall of the drainage inspection well according to the inner wall diameter of the drainage inspection well, which helps to improve the detection accuracy of the detection component 632; the detection component 632 can be at least one of a detection radar, an ultrasonic sensor, and an infrared sensor. Through the detection of the detection component 632, the defect information around the drainage inspection well, such as cracks and corrosion, can be obtained to provide data support for subsequent analysis and processing.

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

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

[0130] Specifically, if Figure 5 As shown, the plurality of detection components 630 are arranged axially symmetrically along the axis of the sliding rod 520, which brings the following technical effects:

[0131] First, the axisymmetric arrangement can ensure that the detection components 630 are evenly distributed in the drainage inspection well, so that defects around the well can be detected more comprehensively and without blind spots. This arrangement helps to reduce missed detections caused by detection blind spots and improve the accuracy and reliability of detection.

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

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

[0134] Finally, the elastic telescopic part 631 can be adaptively adjusted according to the inner wall diameter of the drainage inspection well to control the distance between the detection component 632 and the inner wall within a certain range, and the axially symmetrically arranged detection component 630 can better adapt to the changes in different well diameters, ensuring that the distance between each detection component 632 and the inner wall of the drainage inspection well is the same, thereby improving the accuracy of detection.

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

[0166] One end of the crossbeam 400 is mounted on the top end of the lifting member 320 .

[0167] Specifically, the two stands 300 have the same structure, and the structure of one of the stands 300 is described in detail here.

[0168] The main body 310 of the vertical frame adopts a ladder-type structure, which is similar to the above-mentioned crossbeam main body 410, thereby improving the space utilization rate of the main body 310 of the vertical frame. The notch of the vertical slide groove 311 faces the direction of the drainage inspection well, and the T-shaped structure on the back of the lifting member 320 matches the notch of the vertical slide groove 311. Driven by the lifter 330, the lifting member 320 slides along the vertical slide groove 311, thereby driving the crossbeam 400 to slide on the two vertical frames 300. At the same time, the vertical slide groove 311 is arranged flush with the vertical column 312 of the vertical frame, so that the lifting member 320 can slide to the top or bottom of the vertical column 312 of the vertical frame; accordingly, one end of the crossbeam 400 is installed at the top of the lifting member 320 to increase the sliding stroke of the crossbeam 400 as much as possible.

[0169] The technical effect of the embodiment of the present application is that the sliding of the beam along the two vertical frames is achieved through the lifting member and the lifter.

[0170] In a possible design, a linear rack 321 is provided on the lifting member 320;

Through the support plate 322, the first gear shaft 3311 is flush with the middle position of the vertical slide slot 311, that is, located in the middle position of the height direction of the vertical slide slot 311. At the same time, the length of the lifter 320 is set to be approximately half of the length of the vertical slide slot 311, because if the length of the lifter 320 is too small or too large, the sliding stroke of the crossbeam 400 will be limited.

[0178] The technical effect of the embodiment of the present application is: the sliding stroke of the beam 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.

[0187] The lower base plate 342 is provided with a plurality of anchor rod holes 345 and a plurality of roller bolt holes 346;

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

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

[0190] Furthermore, when the truss device 200 is fixed, the truss device 200 can be reinforced through the anchor holes 345 and the anchors matched therewith.

[0191] The roller bolt hole 346 penetrates the lower bottom plate 342, and the jack 343 and the roller 347 can realize the overall movement of the truss device 200. When moving the truss device 200, first, the truss device 200 is lifted as a whole by 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 can contact the ground; finally, the truss device 200 is quickly transferred as a whole by the roller 347, so as to continuously carry out the inspection work of multiple drainage inspection wells. The steps of fixing the truss device 200 are similar to the steps of moving the truss device 200, and will not be repeated in the embodiments of the present application.

Due to the gravity of the second sliding rod 540 and the water jet assembly 610, the hoisting rope of the hoisting motor 700 is in a taut state.

[0262] S1026, start the hoisting motor 700, and gradually lower the second sliding rod 540 and the water jet assembly 610. During the lowering process, the first sliding rod 530 also moves downward due to gravity, until the hook plate 533 of the first sliding rod 530 is hooked on the inner socket 512 of the fixed rod 510, and the first sliding rod 530 no longer moves downward. Continue to lower 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 with the strip block 531 of the first sliding rod 530, and the second sliding rod 540 will not rotate loose.

[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.

[0270] S1033, gradually lift the second sliding rod 540 and the panoramic quantization assembly 620 until the inspection is completed.

[0274] The technical effects of the embodiments of the present application are: there is no need for technical personnel to go down the well to work, which improves the safety of drainage inspection well detection; a truss device that is easy to install and disassemble is proposed, which can meet the detection needs of various conventional depth drainage inspection wells, and is easy to install and occupies little space.

[0275] In one possible design, Fig. 20 This is a schematic diagram of the structure of the detection component provided in the embodiment of the present application. Figure 5 and Fig. 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 through the telescopic support frame 682, and the second end of the traveling track 681 is mounted on the fixed base 6311 through the fixed support frame 683; the distance between the first end of the traveling track 681 and the cross beam 400 is smaller than the distance between the second end of the traveling track 681 and the cross beam 400;

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

[0279] Specifically, the structures of the multiple elastic stretchable members 631 are the same, and the structure of one of the elastic stretchable members 631 is described in detail here.

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

[0281] The main structure of the inner support member 6312 is a traveling track 681, which is installed on the fixed base 6311 through a telescopic support frame 682 and a fixed support frame 683, and then installed on the sliding rod 520. The telescopic support frame 682 is installed at the first end of the traveling track 681, that is, the rear end of the traveling track 681; the fixed support frame 683 is installed at the second end of the traveling track 681, that is, the front end of the traveling track 681, and 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, and the plane formed by the traveling track 681 is enlarged, so that it can be suitable for a well wall with a larger diameter; when the push-pull member 6313 pulls the traveling track 681, the traveling track 681 rotates around its second end in a direction close to the fixed base 6311, and the telescopic support frame 682 is compressed accordingly, and the plane formed by the traveling track 681 is reduced, so that it can be suitable for a well wall with a smaller diameter.

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

[0284] In a possible design, both ends of the fixed base 6311 are provided with assembly holes 671, and the assembly holes 671 are used to mount 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 member 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 mounted on the abutment frame 672, the connecting plate 693 is mounted 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 installed on the connecting plate 693 , and the second end of the telescopic connecting arm 694 is installed on the traveling crawler 681 .

[0289] Specifically, the abutment frame 672 is disposed at the first end of the fixed rod 510, that is, the end of the fixed rod 510 close to the cross beam 400, so the first end of the fixed rod 510 is equivalent to the abutment end. The closed end of the telescopic cylinder 691 is mounted on the abutment frame 672, so that the closed end of the telescopic cylinder 691 can remain relatively still relative to the fixed rod 510.

[0290] The following content is an example of the plane change formed by the traveling crawler 681 provided in the embodiment of the present application:

[0291] In the first case, when the connecting plate 693 is actively pulled toward the direction close to the abutment frame 672, the first end of the telescopic connecting arm 694 moves toward the direction close to the abutment frame 672, and the traveling track 681 is pulled by the telescopic connecting arm 694, and the plane formed by it is reduced; 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 connecting plate 693 and the first end of the telescopic connecting arm 694 move in a direction away from the abutment frame 672, and the plane they form is reset.

[0293] In the second case, when the traveling crawler 681 moves backward and the diameter of the drainage inspection well is linearly reduced, the first end of the traveling crawler 681 is pressed back, and the second end of the telescopic connecting arm 694 is pressed back, and the first end of the telescopic connecting arm 694 and the connecting plate 693 move toward the direction close to the abutment frame 672. The subsequent content is 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 in the direction away from the abutment frame 672, the first end of the telescopic connecting arm 694 moves in the direction away from the abutment frame 672, and the traveling track 681 is pushed by the telescopic connecting arm 694, and the plane formed by it increases; 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 pushing of the connecting plate 693 stops, 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 the embodiment of the present application is that the plane formed by the traveling track can be actively or passively adjusted through the push-pull member 6313.

[0297] In a 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 retracting rods 6933 and a retracting plate 6934;

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

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

[0301] The first ends of the two retracting rods 6933 are respectively mounted on the push plate 6932; the second ends of the two retracting rods 6933 are respectively mounted on the retracting plate 6934; the two retracting rods 6933 and the two pushers 675 are symmetrical along the central cross-section of the telescopic rod in the vertical direction;

[0302] The retraction plate 6934 is installed on the output shafts of the two pushers 675 respectively; the two pushers 675 are used to drive the retraction plate 6934 to move towards the direction close to the abutment frame 672.

[0303] Specifically, the connecting plate 693 realizes the movement towards or away from the abutment frame 672 in the above embodiment through the sliding block 6931 .

[0304] The push plate 6932 is arranged above the sliding block 6931, and a telescopic rod is installed at the middle position of the push plate 6932 in the direction of the abutment frame 672. The first ends of the two retraction rods 6933 are respectively installed at the top position of the push plate 6932 in the direction of the abutment frame 672; the second ends of the two retraction rods 6933 are respectively 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 cross-section of the telescopic rod in the vertical direction.

[0305] The retraction plate 6934 is installed on the same side of the two retraction rods 6933, and the output shafts of the two pushers 675 are installed. The pushers 675 are fixed on the bracket 673, and the pushers 675 can remain relatively still relative to the fixed rod 510. When the output shaft of the pusher 675 extends, it drives the retraction plate 6934 to move in the direction close to the abutment frame 672, and the retraction plate 6934 drives the pusher plate 6932 of the connecting plate 693 to maintain the same movement, realizing the active pulling of the connecting plate 693 in the first case mentioned above.

[0306] The technical effect of the embodiment of the present application is: the active pulling of the push plate of the connecting plate is realized by the pusher, the retraction plate and the two retraction rods; the stability of the actively pulled push plate is improved by the two symmetrically arranged retraction rods and the two pushers.

[0307] In one possible design, Fig.19 As shown, when the depth of the drainage inspection well increases, the inner wall diameter of the drainage inspection well 100 increases accordingly or remains unchanged;

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

[0309] Specifically, when the detection assembly 630 is not lowered into the drainage inspection well 100, since the wellhead diameter of the drainage inspection well is generally small, the pusher 675 is activated and pushed to drive the retracting plate 6934 to move toward the direction close to the abutment frame 672, thereby reducing the plane formed by the traveling track 681.

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

[0311] The technical effect of the embodiment of the present application is that through the pusher and the telescopic spring, the traveling track is not always parallel to the fixed base, and the posture 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 mentioned above.

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

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

[0315] The first end of the lower rod column 6822 is mounted 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 column 6822;

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

[0318] Specifically, the structures of the telescopic support frame 682 and the telescopic connecting arm 694 are similar, and the structure of the telescopic support frame 682 is described in detail here.

[0319] The telescopic support frame 682 includes an upper column 6821 and a lower column 6822 which are respectively installed on the traveling track 681 and the fixed base 6311, wherein a cylindrical cavity is provided in the upper column 6821; a connecting rod 6823 is provided between the upper column 6821 and the lower column 6822, the first end of the connecting rod 6823 is inserted into the cylindrical cavity 6825, the second end of the connecting rod 6823 is fixedly connected to the lower column 6822, and a buffer spring 6824 is sleeved on the connecting rod 6823, and the buffer spring 6824 can be telescoped between the upper column 6821 and the lower column 6822.

[0320] The technical effect of the embodiment of the present application is: through the cylindrical cavity and the buffer spring, the impact when the traveling track is pushed and pulled is reduced, and the stability of the detection components is improved.

[0321] In a 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 along the central cross-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 arranged in pairs, and the technical effect is: the axisymmetric arrangement helps to balance the weight distribution and torque distribution on the traveling track, thereby enhancing the stability of the traveling track.

[0323] The detection assembly 630 is installed on the detection assembly 630 through the assembly hole 671 , and the remaining steps are similar to the installation of the water jet assembly 610 or the panoramic quantization assembly 620 , which will not be repeated in this embodiment.

[0324] The detection assembly 630 is used to detect defects around the drainage inspection well 100, including the following steps:

[0325] S1041. Lower the detection assembly 630 to a suitable position at the bottom of the well, and retract the pusher 675 to enlarge the plane formed by the traveling crawler 681.

[0326] S1042, gradually lifting the detection assembly 630 until the inspection is completed. The lowering and lifting of the detection assembly 630 is similar to the lowering and lifting of the water jet assembly 610, and will not be described in detail in this embodiment.

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

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

[0329] In other embodiments, when the telescopic spring 692 resets the connecting plate 693, the plane formed by the traveling crawler 681 is reset. At this time, the traveling crawler 681 and the detection element 632 installed thereon just fit the well 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 released as required, the position of the detection assembly 630 relative to the drainage inspection well is adjusted, and the detection from bottom to top is repeated multiple times.

[0331] Specifically, the detection components 630 are arranged in two groups, with a total of four. Due to the working principle of the detection radar component, each working principle can only complete the detection of a small arc range, and the covered well wall area is limited. The rotation connection of the mounting plate 443 relative to the clamping plate 442 can complete more detections by adjusting the orientation after completing a bottom-up detection, so as to cover a wider well wall area.

This rod group is different from the rod group including the fixed rod, the first sliding rod and the second sliding rod, and is only applicable to the detection assembly, but not to the water jet assembly and the panoramic quantization assembly.
