Description

Technical Field

[0001] This application relates to the technical field of drainage structures, and particularly to a truss device. Background Art

[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 peeling, and water leakage. These defects not only affect the normal use of drainage inspection wells but may also cause potential safety hazards such as voids around the wells, ground subsidence around the wells, and uneven settlement of the well body.

[0003] For the various defects commonly existing in existing drainage inspection wells, it is particularly important to conduct a comprehensive and detailed inspection. Currently, the inspection of drainage inspection wells mainly relies on periscope equipment to obtain the internal images of the inspection wells, but this method has deficiencies in inspecting the structural quality of the well body and the development of defects around the wells.

[0004] Therefore, it is necessary to use special inspection equipment for inspection.

In addition, a truss device provided in this application is only an example, and the truss device may also include more or less content.

[0093] The technical solutions of this application will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe this application in conjunction with the drawings.

[0094] To clearly understand the technical solutions of this application, the solutions of the prior art will be introduced in detail first.

[0095] As an auxiliary facility connecting drainage pipes, the health status of a drainage inspection well is directly related to the operation efficiency and safety of the entire drainage system. It not only provides a necessary entrance for the maintenance of drainage pipes, but also undertakes the important responsibilities of monitoring the pipeline status, preventing blockages and leaks. However, due to the influence of the external environment, defects such as well wall corrosion, structural layer peeling, and water leakage often occur in drainage inspection wells. Among them, well wall corrosion is mainly caused by chemical reactions between minerals, acidic substances or alkaline substances in groundwater and well wall materials. This corrosion effect will gradually weaken the strength of the well wall materials, and in severe cases, it may even cause the well wall to perforate, affecting the overall stability of the well body; structural layer peeling is mainly caused by material aging, poor construction quality or long-term uneven stress, which not only affects the appearance 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 may also pollute the surrounding environment. In addition, long-term water leakage will accelerate the erosion of the soil around the well, forming cavities, further threatening the safety of the drainage inspection well and its surrounding facilities. These defects not only affect the normal use of the drainage inspection well, but may also cause safety hazards such as cavities around the well, ground collapse around the well, and uneven settlement of the well body.

[0096] In view of the various defects commonly existing in existing drainage inspection wells, it is particularly important to conduct a comprehensive and detailed inspection. Currently, 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 inner surface conditions of the wells, but it has deficiencies in detecting the structural quality of the well body and the development of defects around the well, and cannot reflect the true service status of the drainage inspection well. Therefore, it is necessary to use special inspection equipment such as sensing components and detecting components for inspection.

[0097] However, in practical applications, the following technical problems exist. The first technical problem is that when lowering a dedicated detection device to a preset position in a drainage inspection well through a hoisting tool, it is difficult to ensure the distance between the detection components of the dedicated detection device and the inner wall of the drainage inspection well, resulting in inaccurate detection results of the development of defects around the well.

[0098] The second technical problem is that different dedicated detection devices have different working principles, and different hoisting tools are required to lower them to the preset position in the drainage inspection well, resulting in a long detection time for the quality of the well structure and the development of defects around the well.

[0099] The third technical problem is that when lowering a dedicated detection device to a preset position in a drainage inspection well through a hoisting tool, it is difficult to ensure the stability during the lowering process, resulting in inaccurate detection results of the quality of the well structure and the development of defects around the well.

[0100] Therefore, in view of the above technical problems, it is found in the research that to solve these problems, first, install the dedicated detection device on the truss device, make the axis of the dedicated detection device coincide with the axis of the drainage inspection well, and limit the movement direction of the dedicated detection device to the vertical direction to ensure the stability during the lowering process of the dedicated detection device; second, detect the defects around the drainage inspection well through the detection components, and ensure the distance between the detection components and the inner wall of the drainage inspection well through symmetrically arranged elastic telescopic members; finally, improve the applicability of the truss device, install multiple dedicated detection devices through a set of truss devices to reduce the replacement time of the dedicated detection device, and thus shorten the detection time of the drainage inspection well.

[0101] Based on the above creative findings, the technical solution of this application is proposed.

[0102] Next, the application scenario of the truss device provided in this application will be introduced.

[0103] Figure 1 It is a schematic diagram of the scenario of the truss device provided in the embodiment of this application. It should be noted that Figure 1 The shown is only an example of the scenario where this application can be applied to help those skilled in the art understand the technical content of this application, but it does not mean that this application cannot be used in other devices, systems, environments or scenarios.

[0104] As Figure 1 shown, for the application scenario of the truss device, this scenario includes: a drainage inspection well 100 and a truss device 200.

[0105] The truss device 200 is installed in the installation area near the wellhead of the drainage inspection well 100, and the truss device 200 is used for the detection of the drainage inspection well 100.

[0106] 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.

[0107] 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:

[0108] Two stands 300, a crossbeam 400, a rod set 500 and a special testing device 600;

[0109] Both ends of the crossbeam 400 are respectively mounted on two vertical frames 300;

[0110] The rod assembly 500 includes: a fixed rod 510 and a sliding rod 520;

[0111] A first end of the fixing rod 510 is mounted on the cross beam 400 , and the sliding rod 520 is used to slide along the fixing rod 510 in a vertical direction.

[0112] In other embodiments, the length of the beam 400 is greater than the wellhead diameter of the drainage inspection well;

[0113] 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.

[0114] 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 .

[0115] 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 truss devices 200 of different diameters.

[0116] 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.

[0117] The cross beam 400 is designed with a sliding mechanism that allows it to slide vertically along the two vertical frames 300. This sliding motion can be achieved through structures such as a toothed rail and gear structure, a guide rail and slider structure, a chute and slide rail structure, or a wheeled sliding structure, as well as driving methods such as motor drive, hydraulic drive, pneumatic drive, or manual drive. This helps to adjust the height of the truss device 200 to adapt to truss devices 200 with different depths.

[0118] In other embodiments, the fixed rod 510 is used to slide horizontally along the cross beam 400;

[0119] The special detection device 600 is installed on the sliding rod 520. The cross beam 400 and the sliding rod 520 are jointly used to lower the special detection device 600 to a preset depth of the drainage inspection well; the special detection device 600 is used to take pictures of the well structure of the drainage inspection well and detect defects around the well.

[0120] 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 cross beam 400. This sliding motion can be achieved through structures such as a linear guide rail and slider structure, a chute and roller structure, a sliding bearing and shaft structure, a magnetic levitation structure, or a chain and belt drive structure, as well as the above driving methods. This helps the special detection device 600 to move horizontally 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 a socket and sliding groove structure, a threaded adjustment structure, a hydraulic cylinder drive structure, or a pneumatic cylinder drive structure, as well as the above driving methods. This helps the special detection device 600 to move vertically to adjust its depth position.

[0121] It should be noted that Figure 2 in, the sliding rod 520 is sleeved on the fixed rod 510, so the fixed rod 510 is not visible.

[0122] Furthermore, the cross beam 400 and the sliding rod 520 work together. When it is necessary to adjust the depth of the special detection device 600, first roughly position by adjusting the height of the cross beam 400, and then make a more precise adjustment by sliding the sliding rod 520 on the fixed rod 510. This 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 technicians according to the specific situation and detection requirements of the drainage inspection well. After the special detection device 600 reaches the preset depth, tasks such as taking pictures of the well structure and detecting defects around the well can be carried out.

It should be noted that Figure 2 In [the figure], by way of example, the dedicated detection device 600 is the water jet component 610.

[0124] The dedicated detection device 600 is a plurality of detection components 630; the plurality of detection components 630 are simultaneously installed 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 components 630 to a preset depth of the drainage inspection well;

[0125] Each detection component 630 includes: an elastic telescopic member 631 and a detection component 632; the detection component 632 is installed on the elastic telescopic member 631, and the elastic telescopic member 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 the circumferential defects of the drainage inspection well.

[0126] Specifically, as Figure 5 shown, the plurality of detection components 630 are arranged axially symmetrically along the axis of the sliding rod 520, bringing the following technical effects:

[0127] First of all, the axially symmetric arrangement can ensure the uniform distribution of the detection components 630 in the drainage inspection well, so as to be able to detect the circumferential defects more comprehensively and without dead angles. This arrangement helps to reduce the missed detection caused by detection blind spots and improve the accuracy and reliability of detection.

[0128] Secondly, the axially symmetric arrangement helps to balance the weight distribution of the detection components 630 on the sliding rod 520, thereby enhancing the stability of the truss device 200. During the detection process, a stable device can better resist external interferences such as wind force and water flow, ensuring the accuracy and consistency of the detection results.

[0129] Thirdly, since the plurality of detection components 630 are arranged axially symmetrically along the axis of the sliding rod 520, the data they obtain is symmetric in space. This symmetry helps to simplify the data processing process and improve the data processing efficiency; at the same time, the symmetric data distribution also helps to more easily discover and identify potential defect patterns, providing more valuable reference information for subsequent maintenance and repair.

[0130] Finally, the elastic telescopic member 631 can adjust the distance between the detection component 632 and the inner wall according to the inner wall diameter of the drainage inspection well, and the axially symmetrically arranged detection components 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, improving the accuracy of detection.

[0131] In other embodiments, the dedicated detection device 600 is any one of the water jet assembly 610, the panoramic quantification assembly 620, and the multiple detection assemblies 630;

[0132] 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 for cleaning the drainage inspection well;

[0133] The panoramic quantification assembly 620 includes: a rotary joint 611, and a sensing component 621 mounted on the rotary joint 611; the sensing component 621 is used for photographing the well structure of the drainage inspection well;

[0134] Each detection assembly 630 includes: an elastic telescopic member 631 mounted on the sliding rod 520, and a detection component 632 mounted on the elastic telescopic member 631; the detection component 632 is used for detecting the defects around the drainage inspection well;

[0135] The sliding rod 520 is used to lower the water jet assembly 610, the panoramic quantification assembly 620, or the multiple detection assemblies 630 to a preset depth of the drainage inspection well.

[0136] Specifically, the dedicated detection device 600 is a detection device dedicated to the detection of drainage inspection wells. It can select any one of the water jet assembly 610, the panoramic quantification assembly 620, or the multiple detection assemblies 630 according to specific detection requirements. This modular design enables the dedicated detection device 600 to flexibly handle different operation tasks and improve the detection efficiency and accuracy.

[0137] As Figure 3 shown, the water jet assembly 610 is dedicated to the cleaning work of drainage inspection well detection. The rotary joint 611 is a component that enables the rotation of the water jet nozzle 612. It allows the water jet nozzle 612 to rotate freely in the horizontal or vertical direction, so as to be able to clean all corners of the drainage inspection well; the water jet nozzle 612 cleans the drainage inspection well through high-pressure water flow. The design of the nozzle usually takes into account factors such as the jet angle, pressure, and flow rate of the water flow to ensure the cleaning effect.

[0138] As Figure 4 shown, the panoramic quantification assembly 620 is dedicated to photographing the well structure of the drainage inspection well. The function of the rotary joint 611 in the panoramic quantification assembly 620 is the same as its function in the water jet assembly 610, realizing the rotation of the sensing component 621; the sensing component 621 can be at least one of a wide-angle camera, sonar radar, lidar, etc. Through the photographing of the sensing component 621, the well structure information of the drainage inspection well can be obtained, providing data support for subsequent analysis and processing.

[0139] As shown Figure 5 in the figure, the detection component 630 is dedicated to detecting the defects around the drainage inspection well. The elastic telescopic member 631 adjusts the distance between the detection component 632 and the inner wall of the drainage inspection well according to the inner 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, an infrared sensor, etc. Through the detection of the detection component 632, the defect information around the drainage inspection well, such as cracks and corrosion, can be obtained, providing data support for subsequent analysis and processing.

[0148] The cross beam main body 410 adopts a ladder-like structure.

[0149] Specifically, the ladder-like structure adopted by the cross beam main body 410 is a flat-laying type. The ladder-like structure means that the cross beam main body 410 is composed of multiple horizontal rods, forming a stable framework. This structure can make more effective use of space, provide more space for the installation of other equipment and the passage of technicians, and improve the space utilization rate of the cross beam main body 410.

[0150] The technical effect of the embodiment of the present application is: through the ladder-like structure, the space utilization rate of the cross beam main body is improved.

[0151] In a possible design, as Figure 2 shown, the cross beam 400 further includes: two double-channel transverse chutes 420, an upper pedestal 430, and a lower pedestal 440;

[0152] The two double-channel transverse chutes 420 are respectively installed on the top surface and the bottom surface of the cross beam main body 410;

[0153] The upper pedestal 430 and the lower pedestal 440 are respectively installed on the corresponding double-channel transverse chutes 420, and both the upper pedestal 430 and the lower pedestal 440 are used to slide along the corresponding double-channel transverse chutes 420;

[0154] On the upper pedestal 430 and the lower pedestal 440, first through holes 450 are respectively opened in the vertical direction;

[0155] The hoisting motor 700 is installed on the upper pedestal 430, the first end of the fixed rod 510 is installed on the lower pedestal 440, and the hoisting rope of the hoisting motor 700 sequentially passes through the first through hole 450 of the upper pedestal 430, the cross beam main body 410, and the first through hole 450 of the lower pedestal 440, and is connected to the sliding rod 520.

[0156] Specifically, Figure 7The structural schematic diagram of the upper pedestal provided by the embodiment of the present application is as follows. As Figure 7 shown, the upper pedestal 430 includes a support member 431 and a support panel 432. The upper pedestal 430 is installed on the double-channel transverse chute 420 on the top surface of the crossbeam main body 410. The support member 431 of the upper pedestal 430 is clamped between the double-channel transverse chute 420, and the upper pedestal 430 slides along the double-channel transverse chute 420 through 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 hoisting motor 700 is installed and fixed on the support panel 432.

[0157] Align the position of the drum 720 with the opening positions of the two first through holes 450, and lower the hoisting rope of the drum 720 through the two first through holes 450 and the crossbeam main body 410 to the lower side of the crossbeam 400 and connect it to the sliding rod 520.

[0158] The technical effect of the embodiment of the present application is that: through the upper pedestal and the double-channel transverse chute, the hoisting motor can slide along the crossbeam; through the lower pedestal and the double-channel transverse chute, the fixed rod can slide along the crossbeam; through the two first through holes and the crossbeam main body, the hoisting rope of the hoisting motor is connected to the sliding rod.

[0159] In a possible design, Figure 8 The structural schematic diagram of the lower pedestal provided by the embodiment of the present application is as follows. As Figure 2 and Figure 8 shown, the lower pedestal 440 includes: a hanging member 441, a clamping plate 442 and a mounting plate 443;

[0160] The hanging member 441 is clamped on the double-channel transverse chute 420 on the bottom surface of the crossbeam main body 410;

[0161] The clamping plate 442 is fixedly installed on the hanging member 441, and the mounting plate 443 is rotatably installed on the clamping plate 442;

[0162] At the corner positions on the bottom surface of the mounting plate 443, a plurality of mounting bolts 4431 are provided; the first end of the fixed rod 510 is installed on the mounting plate 443 through the plurality of mounting bolts 4431.

[0163] Specifically, the lower pedestal 440 is installed on the double-channel transverse chute 420 on the bottom surface of the crossbeam main body 410, and the lower pedestal 440 slides along the double-channel transverse chute 420 through the hanging member 441.

[0164] The mounting plate 443 is rotatably mounted on the clamping plate 442, which can be achieved by a rotating shaft or a rotating pin. To reduce friction and wear, bearings can be installed on the contact surfaces of the two, or sliding surfaces can be made of lubricating materials; when necessary, the rotational connection can be locked by a lock nut, a lock washer, or by using frictional force. The function of the rotational connection is to appropriately rotate the sliding rod 520 when installing the dedicated detection device 600 onto the sliding rod 520 to reduce the installation difficulty of the dedicated detection device 600.

[0165] A plurality of mounting bolts 4431 are provided on the mounting plate 443. Correspondingly, a plurality of bolt holes matching the plurality of mounting bolts 4431 are formed on the fixed rod 510. The first end of the fixed 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.

[0166] The technical effect of the embodiment of the present application is that the first end of the fixed rod is mounted on the crossbeam main body through the lower pedestal.

[0167] In a possible design, as Figure 2 shown, both of the two vertical frames 300 include: a vertical frame main body 310, a lifting member 320, and a lifter 330;

[0168] The vertical frame main body 310 adopts a ladder-like structure;

[0169] On the vertical column 312 of the vertical frame main body 310, a vertical sliding groove 311 is formed on the side close to the rod group 500; the vertical sliding groove 311 is arranged flush with the vertical column 312 of the vertical frame;

[0170] The lifting member 320 is mounted on the vertical sliding groove 311, and the lifter 330 is used to drive the lifting member 320 to slide along the vertical sliding groove 311;

[0171] One end of the crossbeam 400 is mounted on the top end of the lifting member 320.

[0172] Specifically, the structures of the two vertical frames 300 are the same. Here, the structure of one of the vertical frames 300 will be described in detail.

[0173] The vertical frame main body 310 adopts a ladder-like structure, similar to the above-mentioned crossbeam main body 410, which improves the space utilization rate of the vertical frame main body 310. The notch of the vertical chute 311 faces the direction of the drainage inspection well. The T-shaped structure on the back of the lifting member 320 matches the notch of the vertical chute 311. Driven by the lifter 330, the lifting member 320 slides along the vertical chute 311, thereby driving the crossbeam 400 to slide on the two vertical frames 300. At the same time, the vertical chute 311 is 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; correspondingly, 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.

[0174] The technical effect of the embodiment of the present application is that: through the lifting member and the lifter, the sliding of the crossbeam along the two vertical frames is realized.

[0175] In a possible design, a linear tooth rail 321 is provided on the lifting member 320;

[0176] The lifter 330 includes a driving motor 331, and the output shaft of the driving motor 331 is set as a first gear shaft 3311; the tooth shape of the first gear shaft 3311 of the driving motor 331 matches the tooth shape of the linear tooth rail 321.

[0177] Specifically, a linear tooth rail 321 is provided on the front surface of the lifting member 320. When the driving motor 331 outputs power, the first gear shaft 3311 rotates, driving the lifting member 320 to slide on the vertical chute 311.

[0178] The technical effect of the embodiment of the present application is that: through the first gear shaft, the sliding of the lifting member along the two vertical chutes is realized.

[0179] In a possible design, both of the two vertical frames 300 include: a support plate 322;

[0180] The support plate 322 is installed on the horizontal column 313 of the vertical frame main body 310, and the lifter 330 is installed on the support plate 322;

[0181] The first gear shaft 3311 is flush with the middle position of the vertical chute 311.

[0182] Specifically, a vertical column 313 of the upright frame is provided at a certain position of the vertical column 312 of the upright frame. The support plate 322 is installed on the horizontal column 313 of the upright frame. The matching electrical box 332 and the driving motor 331 of the lifter 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 chute 311, that is, located at the middle position in the height direction of the vertical chute 311. At the same time, the length of the lifting member 320 is set to be approximately half of the length of the vertical chute 311. The reason is that if the length of the lifting member 320 is too small or too large, the sliding stroke of the cross beam 400 will be restricted.

[0183] The technical effect of the embodiment of the present application is: through the positional relationship between the first gear shaft and the vertical chute, and the length relationship between the lifting member and the vertical chute, the sliding stroke of the cross beam is increased.

[0184] In a possible design, both of the two upright frames 300 include: a base 340;

[0185] The upright frame body 310 is vertically installed on the base 340;

[0186] A diagonal bracing support frame 350 is provided at the connection between the upright frame body 310 and the base 340;

[0187] A rib plate 360 is provided at the connection between the cross beam 400 and the lifting member 320.

[0188] Specifically, the connection line of the centers of the two bases 340 and the plane formed by the two upright frame bodies 310 both pass through the center of the wellhead of the drainage inspection well, so as to facilitate the axis of the cross beam 400 to coincide with the axis of the drainage inspection well. In addition, both the diagonal bracing support frame 350 and the rib plate 360 are used to improve the connection stability of the truss device 200.

[0189] In a possible design, Figure 9 is the structural schematic diagram of the base provided by the embodiment of the present application Figure 1 ; Figure 10 is the structural schematic diagram of the base provided by the embodiment of the present application Figure 2 ; Figure 11 is the structural schematic diagram of the roller provided by the embodiment of the present application. As Figures 9 to 11 shown, the base 340 includes: an upper base plate 341, a lower base plate 342 and a jack 343;

[0190] Second through holes 344 are respectively provided at the central positions of the upper base plate 341 and the lower base plate 342;

[0191] The base of the jack 343 abuts against the horizontal column 313 of the upright frame body 310 of the upright frame. The ejector 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;

[0192] A plurality of anchor bolt holes 345 and a plurality of roller bolt holes 346 are formed in the lower bottom plate 342;

[0193] When the truss device 200 is lifted by the jack 343, each roller bolt hole 346 is used to install or remove the roller 347, and the roller 347 is used to move the truss device 200.

[0194] Specifically, the jack 343 penetrates through the upper bottom plate 341, the base of the jack 343 abuts against the vertical column 313 of the vertical frame, and the ejector rod of the jack 343 can retract between the upper bottom plate 341 and the lower bottom plate 342. At this time, the truss device 200 is fixed; the ejector rod of the jack 343 can also extend out of the lower bottom plate 342. At this time, the truss device 200 is lifted.

[0195] Further, when the truss device 200 is fixed, the truss device 200 can be strengthened through the anchor bolt holes 345 and the matching anchor bolts.

[0196] The roller bolt holes 346 penetrate through 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 integrally by the jack 343, and the roller 347 is installed in the roller bolt hole 346; second, the jack 343 is retracted, and the roller 347 can contact the ground; finally, the overall rapid transfer of the truss device 200 is carried out through the roller 347, so as to continuously carry out the detection operation 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 elaborated in the embodiments of the present application.

[0197] The technical effect of the embodiment of the present application is that the overall movement of the truss device is realized through the jack and the roller.

[0199] 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;

[0200] 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;

[0201] The rotary joint 611 or multiple elastic telescopic members 631 are both installed on the second sliding rod 540.

[0202] Specifically, the fixed rod 510 is sleeved on the first sliding rod 530. The first sliding rod 530 is equivalent to an inner column, and the fixed rod 510 is equivalent to a middle column; the second sliding rod 540 is sleeved on the fixed rod 510, and the second sliding rod 540 is equivalent to an outer column.

[0203] When the dedicated detection device 600 is not lowered, the three are sleeved together, and the length of the rod group 500 is the shortest; when the dedicated detection device 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, and 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 respectively located at both ends of the first sliding rod 530, and the length of the rod group 500 is the longest.

[0204] The technical effect of the embodiment of the present application is that the dedicated detection device is lowered through the first sliding rod and the second sliding rod.

[0205] In a possible design, the fixed rod 510, the first sliding rod 530, and the second sliding rod 540 are all hollow rectangular shell structures;

[0206] At the middle position of each side surface of the fixed rod 510, a first slit 511 is opened along the length direction of the fixed rod 510, penetrating the fixed rod 510.

[0207] The outer wall size of the first sliding rod 530 matches the inner wall size of the fixed rod 510; at the middle positions of the outer walls of two opposite side surfaces of the first sliding rod 530, strip blocks 531 matching the first slit 511 are both provided; the strip blocks 531 of the first sliding rod 530 are used to slide along the fixed rod 510 through the two first slits 511.

[0208] At the middle positions of the other two opposite side surfaces of the first sliding rod 530, second slits 532 are opened along the length direction of the first sliding rod 530, not penetrating the first sliding rod 530; the width of the second slit 532 is equal to the width of the first slit 511.

[0209] The inner wall size of the second sliding rod 540 matches the outer wall size of the fixed rod 510; at the middle positions of the inner walls of two opposite side surfaces of the second sliding rod 540, pulling members are both provided; the thickness of the pulling members is less than the width of the first slit 511; the second sliding rod 540 is used to slide along the fixed rod 510 through the two first slits 511 and slide along the first sliding rod 530 through the two second slits 532.

[0210] Specifically, in the fixed rod 510, both ends of the first slotted portion 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 slotted portion 511 and the strip block 531 form a chute and a sliding rail structure, realizing the sliding of the first sliding rod 530 along the fixed rod 510. The first end of the second slotted portion 532 is flush with the first end of the first sliding rod 530, and there is a certain distance between the second end of the second slotted portion 532 and the second end of the first sliding rod 530. In the second sliding rod 540, the length of the pulling member is less than the lengths of the first slotted portion 511 and the second slotted portion 532. The pulling member and the first slotted portion 511 form a chute and a sliding rail structure, realizing the sliding of the second sliding rod 540 along the fixed rod 510. The pulling member and the second slotted portion 532 form a chute and a sliding rail structure, realizing the sliding of the second sliding rod 540 along the first sliding rod 530.

[0211] In addition, when the second sliding rod 540 slides along the first sliding rod 530, the second sliding rod 540 fits with the strip block 531 of the first sliding rod 530, and the second sliding rod 540 will not rotate and become loose.

[0212] The technical effect of the embodiment of the present application is that the relative sliding between the fixed rod, the first sliding rod and the second sliding rod is realized through the slotted portion, the strip block and the pulling member.

An even number of splicing plate members 543 are symmetrically arranged on the half side surface of the first end of the symmetric member 541. For example, there can be two splicing plate members 543. A preset bolt hole is formed in each splicing plate member 543. The two symmetric members 541 are spliced into the second sliding rod 540 through the above-mentioned plurality of splicing plate members 543 and mounting bolts matching the preset bolt holes.

[0257] Furthermore, Figure 19 is a schematic structural diagram of the drainage inspection well in the inspection preparation stage provided by the embodiment of the present application. As Figure 19 shown, the drainage inspection well in the inspection preparation stage includes:

[0258] At the end of the upstream pipe section 110 and the beginning of the downstream pipe section 120 of the drainage inspection well 100, an annular airbag 130 is installed. After the annular airbag 130 is inflated, it closely adheres to the inner wall of the pipe to form a seal. The two annular airbags 130 are connected by a diversion hose 140, and the water in the upstream pipe section 110 flows to the downstream pipe section 120 through the diversion hose 140.

[0259] S102. Install the water jet assembly on the rod group, adjust the depth of the water jet assembly in the drainage inspection well through the rod group, and clean the drainage inspection well through the water jet assembly.

[0260] Specifically, installing the water jet assembly 610 includes the following steps:

[0261] S1021. Install the rotary joint 611 at the second end of the second sliding rod 540.

[0263] S1023. Install the water jet nozzle 612 on the rotating part 6112.

[0264] Cleaning the drainage inspection well 100 through the water jet assembly 610 includes the following steps:

[0265] S1024. Adjust the upper pedestal 430 and the lower pedestal 440 on the cross beam 400 to appropriate positions, and restrict the rotation of the mounting plate 443 relative to the clamping plate 442.

[0266] S1025. Adjust the bolt to disengage the second sliding rod 540 from the lower pedestal 440, and keep the fixed rod 510 still fixed at the bottom of the lower pedestal 440. Due to the gravitational action of the second sliding rod 540 and the water jet assembly 610, the lifting rope of the hoist motor 700 is in a taut state.

[0267] 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 downward due to the gravitational action until the hanging 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 stops moving 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 and become loose.

[0268] 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 rotating motor 6113, the water jet nozzle 612 rotates along with the rotating part 6112 to complete the deep cleaning of the well wall at the same depth.

[0269] S1028, gradually lift the second sliding rod 540 and the water jet assembly 610 by the hoisting motor 700, and control the lifting speed within a reasonable range, so as to complete the fine cleaning of the inner wall of the drainage inspection well 100 from bottom to top. After lifting to a certain height, the baffle 544 of the second sliding rod 540 forces the first sliding rod 530 to retract into the fixed rod 510 again.

[0270] 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 lifted to above the wellhead of the drainage inspection well 100, the second docking plate 545 is installed on the lower pedestal 440, and the waste water in the well generated by the cleaning is sucked to the surface for centralized treatment.

[0272] Specifically, installing the panoramic quantization component 620 and photographing the well structure of the drainage inspection well 100 through the panoramic quantization component 620 includes the following steps:

[0273] S1031 , disassemble the water jet assembly 610 , and install the panoramic quantization assembly 620 on the second end of the second sliding rod 540 .

[0274] S1032, restart the hoisting motor 700, gradually lower the second sliding rod 540 and the panoramic quantization component 620 to the appropriate position at the bottom of the well, activate the sensing component 621, and the wide-angle camera starts to take high-definition images of the well structure; under the operation of the rotating motor 6113, the sensing component 621 rotates with the rotating part 6112, driving the sonar radar and / or laser radar to rotate. Among them, the high-definition image collected by the wide-angle camera and the data collected by the sonar radar and / or laser radar can be processed to generate a panoramic expansion map of the inner wall of the drainage inspection well 100, so as to realize the refined detection of the size parameters of each height position of the inspection well and defects such as deformation, corrosion and cracks.

[0275] S1033, gradually lift the second sliding rod 540 and the panoramic quantization assembly 620 until the inspection is completed. The lowering and lifting of the panoramic quantization assembly 620 is similar to the lowering and lifting of the water jet assembly 610, and will not be repeated in this embodiment.

[0276] S104. Install multiple detection components on the rod group, adjust the depths of the multiple detection components in the drainage inspection well through the rod group, and detect the defects around the well through the multiple detection components.

[0277] The installation, lowering, and lifting of the detection component 630 are similar to those of the water jet component 610, and will not be elaborated in this embodiment.

[0278] After the detection is completed, gradually remove the truss device 200 in the installation order, or move the truss device 200 to other drainage inspection wells, and perform post-construction cleaning around the well. After all the operation tasks are completed, process and analyze the obtained data of the well structure photography and the data of the detection of the defects around the well to obtain the size parameters, material compactness at each depth of the drainage inspection well, detect the defects such as deformation, corrosion, and cracks of the well, as well as the leakage and cavity conditions around the well, and determine the repair and renewal plan for the drainage inspection well.

[0279] The technical effects of the embodiments of the present application are as follows: It is not necessary for technicians to work in the well, which improves the safety of the detection of drainage inspection wells; a truss device that is convenient for installation and disassembly is proposed, which can meet the detection requirements of drainage inspection wells with various conventional depths, and is easy to install and occupies a small space.

[0280] In a possible design, Figure 20 is a schematic structural diagram of the detection component provided by the embodiments of the present application. As Figure 5 and Figure 20 shown, each elastic telescopic member 631 includes: a fixed base 6311, an inner support member 6312, and a push-pull member 6313;

[0281] The fixed base 6311 is installed on the sliding rod 520;

[0282] 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 installed on the fixed base 6311 through the telescopic support frame 682, and the second end of the traveling track 681 is installed 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 less than the distance between the second end of the traveling track 681 and the cross beam 400;

[0283] The first end of the push-pull member 6313 is installed on the fixed base 6311, and the second end of the push-pull member 6313 is installed on the traveling track 681. The second end of the push-pull member 6313 is located between the first end 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 cross beam 400 is less than the distance between the second end of the traveling track 681 and the cross beam 400.

[0284] Specifically, the structures of multiple elastic expansion and contraction members 631 are the same. Here, the structure of one of the elastic expansion and contraction members 631 will be described in detail.

[0285] The inner support member 6312 is arranged at the second end of the fixed rod 510, that is, the end of the fixed rod 510 far from the cross beam 400. When the detection assembly 630 is lowered, the detection component 632 mounted on the elastic expansion and contraction member 631 is closer to the bottom of the drainage inspection well.

[0286] The main structure of the inner support member 6312 is a traveling track 681. The traveling track 681 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. The telescopic support frame 682 is closer to the cross beam 400 than the fixed support frame 683.

[0287] When the pushing and pulling 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, and it can be applicable to a well wall with a larger diameter; when the pushing and pulling 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. The plane formed by the traveling track 681 decreases, and it can be applicable to a well wall with a smaller diameter.

[0288] 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 component and the inner wall of the drainage inspection well is controlled, and the detection accuracy is improved.

[0289] In a possible design, assembly holes 671 are opened at both ends of the fixed base 6311. The assembly holes 671 are used to install the fixed base 6311 on the outer side surface of the sliding rod 520;

[0290] A contact frame 672 is further arranged on the fixed base 6311;

[0291] The pushing and pulling member 6313 includes: a telescopic cylinder 691, a telescopic spring 692, a connecting plate member 693, and a telescopic connecting arm 694;

[0292] The closed end of the telescopic cylinder 691 is installed on the contact frame 672. The connecting plate member 693 is installed on the telescopic rod of the telescopic cylinder 691, and the telescopic spring 692 is sleeved on the telescopic rod;

[0293] The first end of the telescopic connecting arm 694 is mounted on the connecting plate member 693, and the second end of the telescopic connecting arm 694 is mounted on the traveling track 681.

[0294] Specifically, the abutting frame 672 is arranged at the first end of the fixed rod 510, that is, the end of the fixed rod 510 close to the cross beam 400. Therefore, the first end of the fixed rod 510 serves as the abutting end. The closed end of the telescopic cylinder 691 is mounted on the abutting frame 672, so that the closed end of the telescopic cylinder 691 can remain relatively stationary with respect to the fixed rod 510.

[0295] The following is a case of the plane change formed by the traveling track 681 provided in the embodiment of the present application:

[0296] In the first case, when actively pulling the connecting plate member 693 in the direction close to the abutting frame 672, the first end of the telescopic connecting arm 694 moves in the direction close to the abutting frame 672, then the traveling track 681 is pulled by the telescopic connecting arm 694, and the plane formed by it decreases; during this period, the telescopic rod of the telescopic cylinder 691 retracts into the closed end, and the telescopic spring 692 is compressed.

[0297] When stopping pulling the connecting plate member 693, the telescopic spring 692 resets the connecting plate member 693, then the connecting plate member 693 and the first end of the telescopic connecting arm 694 move in the direction away from the abutting frame 672, and the plane formed by them resets.

[0298] In the second case, during the backward movement of the traveling track 681, when the diameter of the drainage inspection well linearly decreases, the first end of the traveling track 681 is pressed back, then 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 member 693 move in the direction close to the abutting frame 672. The subsequent content is similar to the first case, and will not be elaborated in this embodiment.

[0299] In the third case, when actively pushing the connecting plate member 693 in the direction away from the abutting frame 672, the first end of the telescopic connecting arm 694 moves in the direction away from the abutting frame 672, then 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.

[0300] When stopping pushing the connecting plate member 693, since the two ends of the telescopic spring 692 are not mounted on the connecting plate member 693 and the closed end of the telescopic cylinder 691, the telescopic spring 692 cannot reset the connecting plate member 693, and the plane formed by the traveling track 681 remains unchanged.

[0301] The technical effect of the embodiment of the present application is that: through the pushing and pulling member 6313, the plane formed by the traveling track is actively or passively adjusted.

[0302] In a possible design, an abutting frame 672, a bracket 673, and a strip-shaped hole 674 are sequentially arranged on a fixed base 6311, and two pushers 675 are installed on the bracket 673;

[0303] The connecting plate member 693 includes: a sliding block 6931, a pushing plate 6932, two retracting rods 6933, and a retracting plate 6934;

[0304] The sliding block 6931 is inserted through the strip-shaped hole 674, and the sliding block 6931 is used for sliding along the strip-shaped hole 674;

[0305] The pushing plate 6932 is simultaneously installed on the sliding block 6931 and the telescopic rod;

[0306] The first ends of the two retracting rods 6933 are both installed on the pushing plate 6932; the second ends of the two retracting rods 6933 are both installed on the retracting plate 6934; the two retracting rods 6933 and the two pushers 675 are both symmetric about the central vertical section of the telescopic rod;

[0307] The retracting plate 6934 is installed on the output shafts of the two pushers 675 respectively; the two pushers 675 are used for driving the retracting plate 6934 to move towards the direction close to the abutting frame 672.

[0308] Specifically, the connecting plate member 693 realizes the movement towards the direction close to or away from the abutting frame 672 in the above-mentioned embodiment through the sliding block 6931.

[0309] The pushing plate 6932 is arranged above the sliding block 6931, and a telescopic rod is installed at the middle position of the pushing plate 6932 towards the direction of the abutting frame 672. The first ends of the two retracting rods 6933 are both installed at the top position of the pushing plate 6932 towards the direction of the abutting frame 672; the second ends of the two retracting rods 6933 are both installed on the retracting plate 6934; the two retracting rods 6933 are located on both sides of the telescopic rod and are symmetric about the central vertical section of the telescopic rod.

[0310] On the same side of the retracting plate 6934 where the two retracting rods 6933 are installed, the output shafts of the two pushers 675 are installed respectively. The pusher 675 is fixed on the bracket 673, and the pusher 675 can remain relatively stationary with respect to the fixed rod 510. When the output shaft of the pusher 675 extends, it drives the retracting plate 6934 to move towards the direction close to the abutting frame 672, then the retracting plate 6934 drives the pushing plate 6932 of the connecting plate member 693 to move in the same way, realizing the active pulling of the connecting plate member 693 in the above-mentioned first case.

[0311] The technical effects of the embodiments of the present application are as follows: Through the pusher, the retraction plate, and the two retraction rods, the active pulling of the push plate for connecting the plate members is realized; through the symmetrically arranged two retraction rods and two pushers, the stability of actively pulling the push plate is improved.

[0312] In a possible design, as Figure 19 shown, when the depth of the drainage inspection well increases, the inner wall diameter of the drainage inspection well 100 increases or remains unchanged;

[0313] 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.

[0314] Specifically, when the detection component 630 is not lowered into the drainage inspection well 100, since the diameter of the wellhead of the drainage inspection well is generally small, the pusher 675 is activated and the pusher 675 pushes, driving the retraction plate 6934 to move towards the direction close to the abutment frame 672, thereby reducing the plane formed by the traveling crawlers 681.

[0315] When the detection component 630 is lowered into the drainage inspection well 100, the pusher 675 is retracted, and then under the action of the telescopic spring 692, the plane formed by the traveling crawlers 681 is increased.

[0316] The technical effects of the embodiments of the present application are as follows: Through the pusher and the telescopic spring, the traveling crawlers are not always parallel to the fixed base, and the attitude can be adaptively adjusted.

[0317] In other embodiments, the telescopic rod of the telescopic cylinder 691 is used to actively push the push plate 6932, realizing the active pushing of the connecting plate member 693 in the above-mentioned third case.

[0318] In a possible design, both the telescopic support frame 682 and the telescopic connecting arm 694 include: an upper rod column 6821, a lower rod column 6822, a connecting rod member 6823, and a buffer spring 6824;

[0319] The first end of the upper rod column 6821 is installed on the traveling crawler 681, and a cylindrical cavity 6825 is opened at the second end of the upper rod column 6821;

[0320] The first end of the lower rod column 6822 is installed on the fixed base 6311 or the connecting plate member 693;

[0321] The first end of the connecting rod member 6823 is inserted into the cylindrical cavity 6825, and the second end of the connecting rod member 6823 is fixedly connected to the second end of the lower rod column 6822;

[0322] The buffer spring 6824 is sleeved on the connecting rod member 6823.

[0323] 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.

[0324] The telescopic support frame 682 includes an upper rod 6821 and a lower rod 6822 respectively installed on the traveling track 681 and the fixed base 6311. A cylindrical cavity is provided inside the upper rod 6821. A connecting rod member 6823 is arranged between the upper rod 6821 and the lower rod 6822. The first end of the connecting rod member 6823 is inserted into the cylindrical cavity 6825, and the second end of the connecting rod member 6823 is fixedly connected to the lower rod 6822. A buffer spring 6824 is sleeved on the connecting rod member 6823, and the buffer spring 6824 can expand and contract between the upper rod 6821 and the lower rod 6822.

[0325] The technical effect of the embodiment of the present application is that 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 component is improved.

[0326] 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 symmetric about the central vertical section of the traveling track 681.

[0327] Specifically, the fixed support frame 683, the telescopic support frame 682, and the telescopic connecting arm 694 are all arranged in pairs. The technical effect is that the axisymmetric arrangement helps to balance the weight distribution and torque distribution on the traveling track, thereby enhancing the stability of the traveling track.

[0328] The detection component 630 is installed on the detection component 630 through the assembly hole 671. The remaining steps are similar to those for installing the water jet component 610 or the panoramic quantification component 620, and will not be elaborated in this embodiment.

[0329] The well perimeter defect detection of the drainage inspection well 100 is carried out by the detection component 630, including the following steps:

[0330] S1041. Lower the detection component 630 to a proper position at the bottom of the well, and the pusher 675 retracts, so that the plane formed by the traveling track 681 is enlarged.

[0331] S1042. Gradually lift the detection component 630 until the inspection is completed. The lowering and lifting of the detection component 630 are similar to those of the water jet component 610, and will not be elaborated in this embodiment.

[0332] In a possible design, the detection component 632 is installed on the traveling track 681;

[0333] The detection component 632 includes a detection radar assembly.

[0334] In other embodiments, when the telescopic spring 692 resets the connecting plate member 693, the plane formed by the traveling track 681 is reset. At this time, the traveling track 681 and the detection component 632 mounted thereon just fit against the wall of the drainage inspection well.

[0335] In other embodiments, in combination with the requirements, the rotational restriction of the mounting plate 443 relative to the clamping plate 442 is released, the position of the detection assembly 630 relative to the drainage inspection well is adjusted, and the up-and-down detection is repeated multiple times.

[0336] Specifically, two sets of four detection assemblies 630 are provided. Due to the working principle of the detection radar assembly, each can only complete detection within a relatively small arc range, covering a limited area of the well wall. The rotational connection of the mounting plate 443 relative to the clamping plate 442 can, after one up-and-down detection, complete more detections by adjusting the orientation, so as to cover a wider area of the well wall.

[0337] In a possible design, another feasible structure of the rod group is provided. This rod group is different from the rod group including the fixed rod, the first sliding rod, and the second sliding rod described above, and is only applicable to the detection assembly, not to the water jet assembly and the panoramic quantification assembly.
