[0028] The water supply pipe network needs to be detected regularly to ensure the normal operation of the pipe network and guarantee the water quality safety of water supply. With the development of technology, when the water supply pipe network is detected, the corresponding detection is often carried out by a detection robot. That is, the detection robot is placed in the water supply pipe, and the detection robot realizes the detection of the pipe by continuously walking in the pipe. The detection robot needs to continuously transmit information and input power during walking, so a cable needs to be connected.

[0029] Generally, the branch pipe is connected with the pipe to be detected, and the branch pipe is vertically arranged with the pipe to be detected. The pipe detection robot moves together with the cable during advancing. The cable is easily damaged by bending during entering the pipe to be detected from the branch pipe, especially the photoelectric composite cable. In the prior art, no device has been designed to protect the cable at the position of the branch pipe.

[0030] The following Figures 1-3 A water supply pipe detection robot push rod device is provided, which comprises a main sleeve 11, a guide rod 12 and a guide assembly 15. The main sleeve 11 is provided with a wire passage in the axial direction. The guide rod 12 is fixedly connected with the main sleeve 11. The guide assembly 15 is rotatably arranged at one end of the main sleeve 11. The guide assembly 15 comprises a guide frame 151 and a tension spring 153. The guide frame 151 has a circular arc section. A plurality of rollers 152 are arranged in the guide frame 151 in the extension direction of the guide frame 151. One end of the guide frame 151 is rotatably connected with the main sleeve 11. One end of the tension spring 153 is connected with the guide frame 151, and the other end of the tension spring 153 is connected with the main sleeve 11. In the working state, the cable is wound around the surface of the roller 152 and is guided by the guide frame 151 from the storage position to the extended position under the action of the cable tension. The cable is pulled into the pipe to be detected 40 from the branch pipe 30 by the pipe detection robot 50. Since the branch pipe 30 and the pipe to be detected 40 are vertically arranged, the cable is easily bent and damaged at the connection position of the branch pipe 30. In the embodiment, the cable is wound around the guide frame 151 under the pulling of the cable, which avoids direct bending and enables the cable to be transitioned from the circular arc section into the pipe to be detected 40, thereby achieving effective protection of the cable.

[0031] Specifically, the main sleeve 11 is a cylindrical structure, and a wire passage is formed in the inside of the main sleeve 11 for the cable to pass through. The guide rod 12 is a long rod structure, which can be used to realize the pushing of the whole device. The guide assembly 15 is used to guide the cable to enter the pipe to be detected 40 from the branch pipe 30, that is, the cable is wound around the guide frame 151, and the cable is transitioned from the branch pipe 30 to the pipe to be detected 40 by the circular arc section of the guide frame 151. This way can avoid damage of the cable due to too small transition angle between the branch pipe 30 and the pipe to be detected 40.

[0032] In specific application, the push rod 12 is applied with a pushing force, so that the device body can extend into the connecting position of the branch pipe 30 and the pipeline 40 to be detected, at this time, the pipeline robot is pushed into the pipeline 40 to be detected, the cable can apply a pulling force to the guide assembly 15 under the driving of the pipeline robot, so that the guide assembly 15 can rotate to the extended position and form a fixed transition arc, and the cable is continuously unwound around the transition arc, thereby achieving effective protection of the cable.

[0033] It can be understood that, in the process of unwinding the cable by the pipeline robot, the cable is in contact with the surface of the roller 152, so as to avoid scratching of the cable and achieve effective protection of the cable. The self-rotation of the roller 152 can reduce the friction between the roller 152 and the cable, so as to achieve smooth unwinding of the cable and reduce the energy consumption of the pipeline robot.

[0034] As shown in Figure 1 , in the storage position, the guide assembly 15 is in the extension direction of the main sleeve 11, that is, the guide assembly 15 does not exceed the outer diameter range of the main sleeve 11, which can facilitate the taking out by the launching sleeve 20 in the recovery process. As shown in Figure 2 , in the extended position, the guide assembly 15 rotates and forms a fixed transition arc segment, thereby achieving transition of the cable movement and avoiding bending of the cable, and achieving effective protection of the cable.

[0035] In specific application, as shown in Figure 3 , the dashed line in the figure represents an optical-electric composite cable. The branch pipe 30 is connected by a flange to the launching sleeve 20, the pipeline robot and the push rod device 10 are all launched into the pipeline 40 to be detected by the launching sleeve 20, and the length of the guide rod 12 can cover the entire launching sleeve 20. At the beginning, the guide assembly 15 is in the storage position under the action of the tension spring 153, as shown in Figure 1 , that is, the guide assembly 15 is stored in the extension direction of the main sleeve 11. At this time, a pushing force is applied to the guide rod 12, so that the push rod device 10 and the pipeline robot are pushed into the pipeline 40 to be detected. After the pipeline robot enters the pipeline, the pipeline robot can move forward and drive the cable to move together. In the process of moving the cable, the cable is wound around the guide assembly 15, so that a pulling force is applied to the guide assembly 15 to drive the guide assembly 15 to rotate. When the guide assembly 15 rotates to the extended position, the arc segment can be used as a transition segment for the cable to pass through, thereby avoiding damage to the cable. Further, after the pipeline robot completes the heat detection, the pipeline robot is recovered. At this time, the guide assembly 15 loses the pulling force applied by the cable, so that the guide assembly 15 returns to the storage position under the action of the tension spring 153, thereby achieving taking out of the device.

[0036] According to some embodiments provided by the present application, the outer side wall of the main sleeve 11 near one end of the guide assembly 15 is provided with a pair of oppositely arranged side plates 13, and a containing space 131 is formed between the side plates 13, so that the guide assembly 15 is located in the containing space 131 when the guide assembly 15 is in the storage position. The guide assembly 15 is in the storage position under the action of the tension spring 153, and at this time, the guide assembly 15 is located in the containing space 131, avoiding the guide assembly 15 exceeding the outer wall diameter of the main sleeve 11, thereby facilitating the recycling of the device and the pushing of the device.

[0037] Specifically, the two side plates 13 are arc-shaped side plates 13, and the containing space 131 is formed between the two by being oppositely arranged. The arrangement of the containing space 131 can play a certain protective role on the guide assembly 15, and the two side edges can facilitate the pushing and taking out of the device.

[0038] According to some embodiments provided by the present application, the end of the main sleeve 11 away from the guide assembly 15 is fixedly provided with a connecting cover 14, the connecting cover 14 is provided with a wire passing hole 141, and the wire passing hole 141 is in communication with the wire passing channel. The arrangement of the connecting cover 14 improves the overall structural stability of the device, and makes the overall structural strength of the device higher.

[0039] Specifically, the connecting cover 14 is constructed as a circular arc cover structure, and the wire passing hole 141 is arranged along the edge of the connecting cover 14. The cable is input into the wire passing channel from the wire passing hole 141.

[0040] As shown in Figure 1 , Figure 2 , the main sleeve 11 is provided with a pair of oppositely arranged guide rods 12, and the guide rods 12 are connected to one end near the connecting cover 14 by bolts. A pair of avoiding grooves 142 are arranged on the connecting cover 14, and the pair of avoiding grooves 142 are arranged one by one corresponding to the pair of guide rods 12, so that the maximum distance between the two guide rods 12 is less than or equal to the outer diameter of the main sleeve 11, making the overall structure of the device more compact.

[0041] In some embodiments, one end of the guide bracket 151 is located in the main sleeve 11 and is hinged to the main sleeve 11, and the other end of the guide bracket 151 is provided with a wire clamping sleeve 16 provided with a wire passing groove 161 for the cable to pass through. Through the hinge of the guide bracket 151, it can rotate around one end of the main sleeve 11 under the action of tension, thereby realizing the switching between the storage position and the extended position. The arrangement of the wire clamping sleeve 16 can further constrain the cable, so that the cable can be stably arranged on the guide bracket 151.

[0042] Specifically, the cable clamping sleeve 16 is a semi-circular structure, which is connected to the guide frame 151 by a locking bolt, and can pass through the cable through the cable through groove 161, and is constrained by the cable through groove 161 to prevent the cable from slipping off, so that the winding of the cable is more stable. Further, the cable clamping sleeve 16 is connected by two bolts, one of which is a common bolt, and the other is a locking bolt. By loosening the bolt design, the cable clamping sleeve 16 can be placed to prevent loosening, and by the common bolt, the end of the cable clamping sleeve 16 can be easily disassembled, facilitating the clamping of the cable.

[0043] According to some embodiments provided by the present application, the guide frame 151 includes a first arc-shaped plate 1511 and a second arc-shaped plate 1512, and the roller 152 is arranged between the first arc-shaped plate 1511 and the second arc-shaped plate 1512 to form a guide channel between the first arc-shaped plate 1511 and the second arc-shaped plate 1512. In the extended state, the cable is wound in the guide channel. The two arc-shaped plates serve as the main frame of the guide frame 151, and by connecting the roller 152 between the two arc-shaped plates, a structure similar to an arc-shaped ladder is formed, and the passage of the cable is achieved.

[0044] Specifically, the roller 152 can rotate, and is arranged between the two arc-shaped plates to form a guide channel. When the cable is in the guide channel, it contacts the roller 152, thereby achieving rapid passage of the cable.

[0045] It can be understood that the entire guide channel is an arc-shaped channel through the two arc-shaped plates, which can avoid the bending of the cable during movement, thereby achieving effective protection of the cable.

[0046] According to some embodiments provided by the present application, the bottom of the first arc-shaped plate 1511 and the second arc-shaped plate 1512 is provided with a limiting portion, so that when the guide frame 151 rotates to the extended position, the limiting portion abuts against the main sleeve 11. During the movement of the cable, a stable arc-shaped section needs to be provided to achieve stable movement of the cable. In this embodiment, by providing the limiting portion, the guide frame 151 can abut against the main sleeve 11 after rotating to the stable position, thereby forming a fixed arc-shaped transition section to achieve stable transition of the cable.

[0047] Specifically, the bottom of the first arc-shaped plate 1511 and the second arc-shaped plate 1512 is provided with a protruding limiting portion, which can abut against the end face of the main sleeve 11 after rotating by a predetermined angle, thereby limiting further rotation of the guide frame 151 and improving its stability.

[0048] According to some embodiments provided by the present application, the first arc-shaped plate 1511 and the second arc-shaped plate 1512 are both provided with mounting blocks 154, and a plurality of mounting holes for connecting the tension spring 153 are arranged on the mounting blocks 154 in a spaced manner. The mounting blocks 154 and the mounting holes can adjust the stress of the guide frame 151, so as to adjust the rotation flexibility of the guide frame 151.

[0049] Specifically, the first arc-shaped plate 1511 and the second arc-shaped plate 1512 are both provided with the tension spring 153, one end of the tension spring 153 is connected with the mounting hole, and the other end of the tension spring 153 extends into the main sleeve 11 and is fixedly connected. In the case of the tension spring 153, the mounting hole located at the distal end will make the tension tighter, that is, the cable needs to exert greater tension to drive the guide frame 151 to rotate, so as to adjust the rotation flexibility of the guide frame 151.

[0050] It can be understood that the design of the two tension springs 153 can make the stress of the guide frame 151 more balanced, and can further improve the stability of the cable when passing through the cable, so as to avoid the problem of stress concentration and durability decline caused by uneven stress.

[0051] According to some embodiments provided by the present application, a through slot 111 is arranged along the axial direction of the main sleeve 11, and the through slot 111 is in communication with the cable passing channel. The design of the through slot 111 can facilitate the clamping of the cable, and realize the quick loading of the cable.

[0052] It can be understood that usually the two ends of the cable are connected with other devices, for example, one end of the cable is connected with a pipe robot, and the other end of the cable is connected with a control device, etc., which makes it difficult for the cable to be loaded into the device by penetrating. In the present embodiment, the design of the through slot 111 makes it possible to directly clamp the cable into the cable passing channel inside the main sleeve 11 through the through slot 111.

[0053] According to some embodiments provided by the present application, limit blocks 17 are detachably arranged at both ends of the cable passing channel, and a connecting shaft 171 is arranged between the limit blocks 17 and located in the through slot 111. The arrangement of the limit blocks 17 can avoid the cable clamped in from sliding out of the through slot 111.

[0054] Specifically, the limit blocks 17 are connected at both ends of the main sleeve 11 and located at the position of the through slot 111, and the connecting shaft 171 penetrates the through slot 111 and is connected with the two limit blocks 17 at both ends, so that the connecting shaft 171 can fill the through slot 111, and avoid the cable inside the main sleeve 11 from being clamped into the through slot 111. Moreover, the detachable connection of the limit blocks 17 can facilitate the clamping of the cable after being detached.

[0055] Specifically, the limiting block 17 is an arc-shaped limiting block 17, which can be detachably connected through bolt connection.

[0056] In some embodiments, one end of the limiting block 17 is hingedly connected to the main body sleeve 11, and the other end of the limiting block 17 is fixedly connected to the main body sleeve 11 through a bolt. The hingedly connected end of the limiting block 17 can facilitate the quick installation of the cable and quickly close the through slot 111.

[0057] Specifically, the limiting block 17 is hingedly connected to enable it to rotate along the hinged position, which can open the through slot 111, that is, the connecting shaft 171 is flipped to the through slot 111, which can facilitate the clamping of the cable. After the cable is clamped, the connecting shaft 171 is flipped to be located in the through slot 111 to achieve its closure. A bolt is used to fasten the limiting block 17.

[0058] Specifically, the limiting block 17 can be connected and fastened by using a non-removable screw during connection, which can prevent the screw from falling off even if it is not tightened during the engineering process.

[0059] From the above description of the embodiments, those skilled in the art can clearly understand that the embodiments use the guide assembly 15 to guide the cable when passing through, which avoids damaging the cable when the cable follows the pipe detection robot 50 to advance, and effectively protects the cable at the connection between the branch pipe 30 and the pipe to be detected 40. Further, the fixed circular arc transition section formed by the guide frame 151 can avoid the bending of the cable when passing through, thereby effectively protecting the cable.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
