[0029] The water supply network needs to be inspected regularly to ensure the normal operation of the network and the safety of the water quality. With the development of technology, the inspection of the water supply network is often carried out by inspection robots. That is, the inspection robot is placed in the water supply pipeline, and the pipeline is inspected by the continuous walking of the inspection robot. The inspection robot needs to continuously transmit information and input power during the walking process, so it needs to be connected to a cable.

[0030] In the related art, conventional cable winches or similar cable stirring devices are used to assist the wires. Such devices usually occupy a large volume and are difficult to adapt to the use of smaller scenes. They often require manual assistance to retract and release the cables, which results in high labor intensity for the staff and low efficiency of retracting and releasing the cables. Therefore, the present invention has newly designed a device structure, which can realize automatic retracting and releasing of the cables through the newly designed structure, and the overall volume is small, which can be applied to more wire scenes.

[0031] Regarding the problems in related technologies, such as Figure 1-5As shown, this example provides a cable guide device for retracting and releasing a cable, including a shell 1, a support plate assembly 2, a driving wheel 3, a driven wheel assembly 4 and a guide wheel assembly 5; an installation chamber is formed in the shell 1, and a driving component 10 is arranged in the installation chamber; the support plate assembly 2 is fixedly arranged on one side of the shell 1, and the support plate assembly 2 includes a first support plate 21 and a second support plate 22, the first support plate 21 is connected to the shell 1, and the second support plate 22 is connected to the first support plate 21 through a connecting member, and an installation gap is arranged between the first support plate 21 and the second support plate 22; the driving wheel 3 is connected to the output end of the driving component 10 , and is located in the installation gap, a wire-passing annular groove 31 is provided on the outer peripheral wall of the driving wheel 3; the driven wheel assembly 4 is fixedly arranged on the support plate assembly 2 and is located above the installation gap, a plurality of driven wheels are arranged in the driven wheel assembly 4, and a matching annular groove 43 is provided on the outer peripheral wall of the driven wheel, and a plurality of driven wheels are arranged on the periphery of the driving wheel 3, and the wire-passing annular groove 31 cooperates with the matching annular groove 43 to form a wire-passing channel for the cable to pass through; the guide wheel assembly 5 is arranged between the first support plate 21 and the second support plate 22, and is located on one side of the driving wheel 3, and the guide wheel assembly 5 is used to guide the cable into the wire-passing channel. When the pipeline inspection robot is operating, its body is located in the pipeline. During the walking operation of the pipeline inspection robot, it is necessary to continuously release the wire to be able to follow the movement of the robot. After the operation is completed, the pipeline inspection robot needs to be controlled to retreat, and it is also necessary to cooperate in collecting the wire. In this embodiment, a wire passage is formed between the driving wheel 3 and the driven wheel, and the cable enters the pipeline to be tested through the wire passage. The driving wheel 3 can rotate under the drive of the driving component 10, and the stable winding and releasing of the wire can be achieved through the coordinated operation of the driving wheel 3 and the driven wheel.

[0032] Specifically, the housing 1 can provide a relatively sealed environment, which can prevent the external environment from affecting the normal operation of the driving component 10, thereby improving the overall stability of the device. The first support plate 21 is fixedly connected to the housing 1 and can serve as a side wall of the installation chamber, which can achieve the closure of the installation chamber and can have a certain spacing with the second support plate 22 to form an installation gap, and the various components of the line are arranged in the installation gap. In this way, the overall thickness of the device can be reduced, so that the overall occupied volume is small, and it can be applied to various narrow construction environments.

[0033] The driven wheel is located above the driving wheel 3, and the annular matching groove on the driven wheel can cooperate with the wire passing annular groove 31 to form a wire passing channel for the cable to pass through. The inner diameter of the wire passing channel is slightly smaller than the outer diameter of the cable, and the driving wheel 3 can rotate under the drive of the driving unit. When the cable passes through the wire passing channel, it will cling to the upper and lower side walls of the wire passing channel, that is, cling to the inner wall surface of the annular matching groove and the wire passing annular groove 31, so that the driving wheel 3 can realize stable movement of the cable when it rotates, and complete the wire laying operation or wire winding operation.

[0034] The guide wheel assembly 5 is used to guide the cable to adjust its output or input direction so as to adapt to the external cable position. In this embodiment, the guide wheel assembly 5 is arranged on one side of the driving wheel 3, so that the cable direction can be changed after the cable passes through the cable channel, thereby adapting to the external cable storage device, making the winding or releasing operation smoother.

[0035] In specific applications, a connecting pipeline is provided on the pipeline to be tested, and a gate valve is provided on the connecting pipeline. Before specific installation, the gate valve is closed to seal the connecting pipeline and the pipeline to be tested, and then a launching sleeve is connected to the connecting pipeline through a flange, and the retractable cable guide device is connected to the top of the retractable cable guide device, and the detection robot and a part of the cable are located in the launching sleeve. After the retractable cable guide device is connected and sealed, the gate valve is opened to connect the connecting pipeline and the pipeline to be tested, so that the detection robot can enter the pipeline to be tested, thereby realizing the detection of the pipeline to be tested. When the detection robot is moving for detection, the retractable cable guide device continuously performs the wire laying operation.

[0036] It is understandable that some water supply pipes are located in underground pipe networks, and when pipeline inspection is performed in some narrow locations, the existing equipment is difficult to arrange due to the large overall volume. In terms of structural layout, the support plate assembly 2 is arranged on one side of the shell 1, that is, the installation gap is located on one side of the shell 1, and the driving wheel 3, the driven wheel assembly 4 and the guide wheel assembly 5 are all located at the installation gap position, so that the overall structure occupies a small space, and it can be directly connected to the top of the launching sleeve to realize the cable release and reeling operations.

[0037] In some embodiments provided by the present invention, the cable guide device for retracting and releasing the cable further includes a disinfection component 6, which is arranged on the first support plate 21 and between the guide wheel assembly 5 and the driving wheel 3, and the disinfection component 6 is used to disinfect the cable. The pipeline detection robot works in the pipeline, and the cable moves with the pipeline detection robot. During the movement of the cable in the pipeline, the surface of the cable will carry some pathogens in the pipeline. In this embodiment, by setting the disinfection component 6, the cable can be disinfected to avoid contamination of the water quality in the pipeline to be tested when releasing the line, and the risk of infection for the staff can also be reduced.

[0038] Specifically, the active wheel 3 and the driven wheel can cooperate to realize the active retraction and release of the cable. The guide wheel assembly 5 is often cooperated with an external cable storage device (such as a cable storage tray, etc.). The disinfection assembly 6 is arranged between the two, which can disinfect the cables input into the wire passage, thereby preventing the cables from carrying pathogens into the pipeline to be tested, and can also disinfect the cables during the wire retraction process to prevent the pathogens from being stored in the cable storage device along with the cables, thereby reducing the risk of infection for staff.

[0039] In specific configuration, the disinfection assembly 6 can be a conventional disinfection device, such as an ultraviolet disinfection device, a thermal disinfection device, or a disinfectant spraying device, etc. Such disinfection devices can effectively disinfect the cable surface to avoid cable contamination.

[0040] It can be understood that by arranging the disinfection assembly 6 between the guide wheel assembly 5 and the driving wheel 3, the overall structure can be made more compact, the overall volume of the device can be reduced, and it can be suitable for narrow installation scenarios.

[0041] In some embodiments, the disinfection assembly 6 includes a limit block 62 and a disinfectant injector 61, both of which are fixedly connected to the first support plate 21, and the disinfectant injector 61 is located above the limit block 62; a disinfection cavity is provided in the limit block 62, the limit block 62 is provided with a cable through hole for the cable to pass through in the horizontal direction, and the top of the limit block 62 is provided with an injection through hole for injecting disinfectant in the vertical direction, and the cable through hole and the injection through hole are both connected to the disinfection cavity. The disinfectant can be retained on the outer surface of the cable, so that it has a certain continuous disinfection effect. In this embodiment, by arranging the disinfectant injector 61 above the limit block 62, it can realize the injection of disinfectant into the disinfection cavity, so that the cable can contact with the disinfectant during the movement, thereby realizing the continuous disinfection of the cable surface.

[0042] Specifically, the output end of the disinfection injector can output disinfectant, and the disinfection injector is located above the limit block 62, so that the disinfectant can be output from its output end and injected into the disinfection cavity through the injection through hole, thereby filling the disinfection cavity with disinfectant.

[0043] It can be understood that the disinfectant injector 61 and the limit block 62 are arranged at intervals in the vertical direction. The disinfectant injector 61 can inject disinfectant into the disinfection cavity. The cable passes through the disinfection cavity through the cable through hole, which can make the cable passing more stable and realize efficient coating of disinfectant to disinfect the cable surface.

[0044] In some embodiments, a liquid absorbing component is provided in the disinfection cavity, and the liquid absorbing component contacts the cable, so that the disinfectant can be applied to the surface of the cable through the liquid absorbing component during the movement of the cable. The liquid absorbing component can absorb the disinfectant, so that the disinfectant can be applied to the surface of the cable during the movement of the cable, thereby achieving the disinfection of the bacteria on the cable surface.

[0045] Specifically, the liquid absorption component includes a sponge block, which is arranged in the disinfection cavity. The disinfectant is injected into the disinfection cavity through a disinfectant injector 61, so that the sponge block absorbs the disinfectant and is in a saturated state. The cable can be continuously coated with disinfectant during the contact between the cable and the sponge, thereby achieving disinfection of the cable surface.

[0046] In specific configuration, the disinfectant injector 61 includes a disinfection tank for storing disinfectant and an injection part connected to the tank mouth of the disinfection tank, an injection pipe is provided on the injection part, the injection pipe is located above the injection through hole, or a part of the injection pipe extends into the injection through hole, and a valve is provided on the injection pipe, and the valve can control the opening and closing of the injection pipe. When the disinfectant needs to be injected, the valve is opened, and the disinfectant can be injected into the disinfection cavity under the action of gravity.

[0047] Furthermore, the valve may be an electrically controlled valve, which can be remotely controlled to achieve remote control of disinfectant injection.

[0048] According to some embodiments provided by the present invention, Figure 3 , Figure 4 As shown, an encoder 7 is also included. The encoder 7 is arranged on the first support plate 21 and is located between the guide wheel assembly 5 and the driving wheel 3. The encoder 7 is in contact with the cable. During the detection process of the pipeline detection robot, its moving distance needs to be monitored in real time. In this embodiment, the setting of the encoder 7 can measure the cable pay-off distance in real time, and then the moving distance of the pipeline detection robot can be monitored.

[0049] Specifically, the encoder 7 adopts a conventional rotary encoder 7, and the encoder 7 includes a metering part and a rotating contact part 71, and the rotating contact part 71 is connected to the metering part, so that the rotating contact part 71 can achieve metering through the metering part when rotating. Specifically, a knurling structure is processed on the surface of the rotating contact part 71, which can increase the surface friction of the rotating contact part 71, thereby preventing the rotating contact part 71 from slipping when contacting the cable, and improving the accuracy of measurement.

[0050] In the specific configuration, the encoder 7 is disposed between the disinfection assembly 6 and the guide wheel assembly 5, which can make the overall structural layout more compact and reduce the overall volume occupancy.

[0051] According to the cable guide device for retracting and releasing the cable provided by the present invention, the driven wheel assembly 4 includes a first driven wheel unit 41 and a second driven wheel unit 42, the first driven wheel unit 41 is arranged directly above the driving wheel 3, the second driven wheel unit 42 is arranged on one side of the driving wheel 3, and at least one driven wheel is provided on the first driven wheel unit 41 and the second driven wheel unit 42. The cable is a relatively flexible cable structure, and the stability of the cable needs to be maintained during the active release and retraction of the cable to avoid affecting the retraction and release of the cable. In this embodiment, at least two driven wheel units can be used to confine the cable to the corresponding wire passing channel, thereby improving the stability of the cable passing and realizing stable transportation of the cable.

[0052] Specifically, the first driven wheel unit 41 can allow the cable to enter the wire passing channel along the approximate tangential direction of the top of the driving wheel 3, and the second driven wheel unit 42 can allow the cable to be output from the approximate tangential direction of one side of the driving wheel 3, which enables the cable to be transmitted roughly around a quarter circle of the driving wheel 3, that is, the wire passing channel is roughly distributed on a quarter circle arc segment of the driving wheel 3, thereby making the cable more stable in the wire passing channel and achieving stable transportation of the cable.

[0053] According to some embodiments provided by the present invention, the second driven wheel unit 42 includes a support frame, on which a plurality of second driven wheel portions are arranged, and the plurality of second driven wheel portions are evenly distributed around the periphery of the driving wheel 3. like Figure 1 , Figure 2 As shown, the support frame has a first fixed end and a second fixed end, the first fixed end is fixedly connected to the first support plate 21 by bolts, and the second fixed end is fixedly connected to the second support plate 22 by bolts. This method can make the connection of the support frame more stable, and multiple driven wheels are connected to the support frame, and the multiple driven wheels are evenly arranged on the periphery of the driving wheel 3, thereby forming a wire passing channel.

[0054] Specifically, Figure 2 As shown, the dashed line segment in the figure represents the cable. The support frame is provided with a first driven wheel structure and a second driven wheel structure, the first driven wheel structure is provided with a first driven wheel, the second driven wheel structure is provided with a third driven wheel and a fourth driven wheel, and correspondingly, the first driven wheel unit 41 is provided with a fourth driven wheel, the first driven wheel, the second driven wheel, the third driven wheel and the fourth driven wheel are arranged on the periphery of the driving wheel 3, and form a quarter of an arc structure, that is, the first driven wheel, the second driven wheel, the third driven wheel and the fourth driven wheel cooperate with the driving wheel 3 to form an arc-shaped wire-passing channel, thereby improving the stability of cable fixing.

[0055] It can be understood that a plurality of driven wheels are connected and arranged along the outer portion of the driving wheel 3 to form an arc-shaped wire-passing channel, which makes the cable more stable when being driven by the driving wheel 3 for releasing or retrieving the cable, and the stability and transmission efficiency are higher.

[0056] According to some embodiments provided by the present invention, the guide wheel assembly 5 includes a fixed guide portion 51 and a movable guide portion 52, the fixed guide portion 51 is fixedly arranged at one end of the support plate assembly 2, and the movable guide portion 52 is rotatably arranged in the installation gap and is located below the fixed guide portion 51; the movable guide portion 52 includes a guide portion body 521 and a positioning rod 522, the guide portion body 521 is provided with a positioning hole 523, and the positioning rod 522 is arranged in the positioning hole 523, so that the movable guide portion 52 is limited to rotate when the movable guide portion 52 is in the working position and the storage position. The movable guide portion 52 is rotatably connected, so that it can reach the storage position and the working position during the rotation process, and is limited by the positioning rod 522 when switching between the two positions.

[0057] Specifically, taking the direction of cable pay-off as an example, the fixed guide portion 51 is located upstream of the cable pay-off direction. The cable is guided by the fixed guide portion 51, disinfected by the disinfection assembly 6, and then driven by the active wheel 3 in the wire passage to pay-off. When necessary, the movable guide portion 52 can rotate to one side of the support plate and form a certain angle with the support plate assembly 2. The movable guide portion 52 can change the angle of the cable entering the device. For example, when the cable is tilted, it can be guided once by the movable guide portion 52, and then guided twice by the fixed guide portion 51, and then input into the device.

[0058] When the movable guide part 52 is in actual operation, under normal conditions, the cable is not input in an inclined direction. At this time, the movable guide part 52 is located in the installation gap. At this time, the positioning rod 522 passes through the positioning hole 523 and is fixed in the through holes of the first support plate 21 and the second support plate 22 accordingly, so that the movable guide part 52 is stably arranged in the installation gap. When input in an inclined direction is required, first, the positioning rod 522 is pulled out. After the positioning rod 522 is pulled out, the movable guide part 52 can rotate. When the positioning hole 523 rotates to the outside of the installation gap, the positioning rod 522 is inserted so that the positioning rod 522 contacts and limits the side wall surfaces of the first support plate 21 and the second support plate 22, thereby limiting the rotation of the movable guide part 52, and further enabling the cable to be input or output in an inclined direction. Figure 6 As shown, the dashed lines represent cables.

[0059] like Figure 4 , Figure 6As shown, the fixed guide portion 51 includes a horizontal guide group and a vertical guide group. The horizontal guide group includes a pair of rotatably arranged guide columns. A passing groove is opened in the middle position of the guide column. The grooves of the two horizontally parallel guide columns form a horizontal guide channel. The corresponding vertical guide group includes a pair of vertically arranged guide columns, and the vertical guide channel is also formed by the grooves on the guide columns. The vertical guide channel and the horizontal guide channel can realize the passage of cables and can achieve a guiding function.

[0060] like Figure 6 As shown, the movable guide portion 52 includes a pair of vertically arranged guide columns, each of which has a groove in the middle, and the grooves on the two parallel guide columns cooperate to form a channel for the cable to pass through.

[0061] According to some embodiments provided by the present invention, Figure 6 As shown, it also includes a transmission mechanism, which is arranged in the installation chamber and is transmission-connected to the output end of the driving component 10, so as to transmit the torque of the driving part to the driving wheel 3. The arrangement of the transmission mechanism can facilitate the design of the overall structure, so that the overall structure occupies a smaller volume, making it suitable for a narrow working environment.

[0062] Specifically, the driving component 10 is arranged in the upper space of the installation chamber, and the transmission mechanism is arranged in the lower space of the installation chamber. This upper and lower distribution method can make the device smaller in size, enrich its use scenarios, and improve its applicability. The transmission mechanism is used to transfer the torque in the vertical direction to the torque in the horizontal direction of the driving wheel 3, so as to realize the driving of the driving wheel 3.

[0063] According to the cable guide device for retracting and releasing the cable provided by the present invention, the transmission mechanism includes a transmission shaft 9, one end of which is provided with a first bevel gear 91 and is located in the installation chamber; the other end of the transmission shaft 9 is rotatably connected to the second support plate 22, and the driving wheel 3 is arranged on the transmission shaft 9 located in the installation gap; correspondingly, a second bevel gear 101 is arranged on the output end of the driving component 10, and the first bevel gear 91 is meshed with the second bevel gear 101 for transmission.
