[0027] 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.

[0028] Usually, the branch pipe is connected to the pipeline to be tested, and the branch pipe is arranged vertically to the pipeline to be tested. The pipeline detection robot will drive the cable to move together during the forward movement. The cable is prone to bending damage during the process of entering the pipeline to be tested from the branch pipe, especially the photoelectric composite cable is more susceptible to damage. However, in the art, there is no device designed to protect the cable at the branch pipe position.

[0029] Combine the following Figure 1-Figure 3 The present invention provides a water supply pipe inspection robot push rod device, which includes a main sleeve 11, a guide rod 12 and a guide assembly 15; a wire passage is provided in the axial direction of the main sleeve 11; the guide rod 12 is fixedly connected to the main sleeve 11; the guide assembly 15 is rotatably arranged at one end of the main sleeve 11, and the guide assembly 15 includes a guide frame 151 and a tension spring 153, the guide frame 151 has an arc segment, and a plurality of rollers 152 are arranged in the guide frame 151, and the plurality of rollers 152 are arranged at intervals along the extension direction of the guide frame 151; one end of the guide frame 151 is rotatably connected to the main sleeve 11; one end of the tension spring 153 is connected to the guide frame 151, and the other end of the tension spring 153 is connected to the main sleeve 11, and in the working state, the cable is wound around the surface of the roller 152, and the guide frame 151 is rotated from the storage position to the extended position under the action of the cable tension. The cable enters the pipeline 40 to be tested from the branch pipe 30 under the pulling of the pipeline detection robot 50. Since the branch pipe 30 and the pipeline 40 to be tested are arranged vertically, the cable is easily bent and damaged at the connection position of the branch pipe 30. In this embodiment, the guide assembly 15 is arranged so that the cable is arranged around the guide frame 151 when being pulled, avoiding direct bending, so that the cable can transition from the circular arc segment to the pipeline 40 to be tested, thereby achieving effective protection for the cable.

[0030] Specifically, the main sleeve 11 is a cylindrical structure, and a wire passage for the cable to pass through is formed inside it. The guide rod 12 is a long rod structure, which can be used to push the device as a whole. The guide assembly 15 is used to guide the cable from the branch pipe 30 into the pipeline to be tested 40, that is, the cable bypasses the guide frame 151, and the arc-shaped section on the guide frame 151 realizes the transition of the cable from the branch pipe 30 to the pipeline to be tested 40. This method can avoid the cable from being damaged due to the small transition angle between the branch pipe 30 and the pipeline to be tested 40.

[0031] In specific applications, by applying a thrust to the guide rod 12, the device body can be extended along the branch pipe 30 to the connection position between the branch pipe 30 and the pipeline 40 to be tested. At this time, the pipeline robot is pushed into the pipeline 40 to be tested, and the cable can apply a pulling force to the guide assembly 15 driven by the pipeline robot, so that the guide assembly 15 can be rotated to the extended position and a fixed transition arc is formed. The cable is wound around the transition arc to continuously pay out the cable, thereby achieving effective protection for the cable.

[0032] It is understandable that, in the process of the cable being pulled and released by the pipeline robot, the cable is in contact with the surface of the roller 152, thereby avoiding scratches on the cable and achieving effective protection of the cable. The self-rotation of the roller 152 can reduce the friction between the cable and the cable, thereby achieving smooth release of the cable and reducing the energy consumption of the pipeline robot.

[0033] like Figure 1 As shown, in the storage position, the guide assembly 15 is located 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 be easily taken out by the delivery sleeve 20 during the recovery process. Figure 2 As shown, in the extended position, the guide assembly 15 rotates and forms a fixed transition arc segment, thereby achieving a transition for the movement of the cable, avoiding bending of the cable, and achieving effective protection for the cable.

[0034] When applying specific Figure 3 As shown, the dotted line in the figure represents the optoelectronic composite cable. The branch pipe 30 is connected to the delivery sleeve 20 through a flange, and the pipeline robot and the push rod device 10 are both delivered into the pipeline 40 to be tested by the delivery sleeve 20. The length of the guide rod 12 can cover the entire delivery sleeve 20. Initially, the guide assembly 15 is in the storage position under the action of the tension spring 153, as shown in FIG. Figure 1 As shown, the guide assembly 15 is stored in the extension direction of the main sleeve 11. At this time, by applying a thrust to the guide rod 12, the push rod device 10 and the pipeline robot are pushed into the pipeline 40 to be tested. After the pipeline robot enters the pipeline, the pipeline robot can move forward and drive the cable to move together. During the movement of the cable, since the cable is wound around the guide assembly 15, a pulling force is applied to the guide assembly 15, thereby driving the guide assembly 15 to rotate. When the guide assembly 15 rotates to the extended position, it can pass through the arc section as a transition section for the cable to pass, thereby avoiding damage to the cable. Further, after the thermal energy detection of the pipeline machine is completed, the pipeline robot is recovered. At this time, since the guide assembly 15 loses the pulling force applied by the cable, the guide assembly 15 returns to the storage position under the action of the tension spring 153, and the device is removed.

[0035] According to some embodiments provided by the present invention, a pair of oppositely disposed side plates 13 are provided on the outer side wall of the main sleeve 11 near one end of the guide assembly 15, and an accommodation space 131 is formed between the side plates 13, so that when the guide assembly 15 is located at the storage position, the guide assembly 15 is located in the accommodation space 131. 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 accommodation space 131, so that the guide assembly 15 is prevented from exceeding the outer wall diameter of the main sleeve 11, thereby facilitating the recovery and pushing of the device.

[0036] Specifically, the two side panels 13 are arc-shaped side panels 13, which are relatively arranged to form a receiving space 131 therebetween. The setting of the receiving space 131 can provide a certain degree of protection for the guide assembly 15, and the two side edges can facilitate the pushing in and taking out of the device.

[0037] According to some embodiments provided by the present invention, a connection cover 14 is fixedly provided on the end of the main sleeve 11 away from the guide assembly 15, and a wire-passing opening 141 is provided on the connection cover 14, and the wire-passing opening 141 is connected to the wire-passing channel. The setting of the connection cover 14 improves the structural stability of the device as a whole, and makes the structural strength of the device as a whole higher.

[0038] Specifically, the connection cover 14 is constructed as an arc cover structure, and the wire passing opening 141 is arranged along the edge of the connection cover 14 , and the cable is input into the wire passing channel through the wire passing opening 141 .

[0039] like Figure 1 , Figure 2 As shown, a pair of guide rods 12 are arranged opposite to each other on the main sleeve 11, and the guide rods 12 are connected to one end of the connecting cover 14 by bolts. A pair of avoidance grooves 142 are arranged opposite to each other on the connecting cover 14, and the pair of avoidance grooves 142 are arranged one by one with 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.

[0040] In some embodiments, one end of the guide frame 151 is located in the main body sleeve 11 and is hinged to the main body sleeve 11; the other end of the guide frame 151 is provided with a wire clamping sleeve 16, and the wire clamping sleeve 16 is provided with a wire groove 161 for the cable to pass through. Through the hinge of the guide frame 151, it can rotate around one end of the main body sleeve 11 under the action of tension, thereby realizing the switching between the storage position and the extended position. The setting of the wire clamping sleeve 16 can further constrain the cable, so that the cable can be stably wound on the guide frame 151.

[0041] Specifically, the cable holder 16 is a semi-annular structure, which is connected to the guide frame 151 by anti-loosening bolts, and can allow the cable to pass through the cable groove 161, which is constrained by the cable groove 161 to prevent the cable from slipping, making the cable winding more stable. Further, the cable holder 16 is connected by two bolts, one bolt is a common bolt, and the other is an anti-loosening bolt. The design of loosening the bolts can prevent the cable holder 16 from loosening, and the common bolts can facilitate the removal of one end of the cable holder 16, which is convenient for the cable to be inserted.

[0042] According to some embodiments provided by the present invention, the guide frame 151 includes a first curved plate 1511 and a second curved plate 1512, and a roller 152 is disposed between the first curved plate 1511 and the second curved plate 1512 to form a guide channel between the first curved plate 1511 and the second curved plate 1512, and the cable is wound in the guide channel when in the extended state. The two curved plates serve as the main frame of the guide frame 151, and the roller 152 is connected between the two curved plates to form a structure similar to an arc-shaped step, and the cable can pass through.

[0043] Specifically, the roller 152 can rotate on its own. It is disposed between the two arc-shaped plates and forms a guide channel. When the cable is in the guide channel, it contacts the roller 152 , thereby enabling the cable to pass quickly.

[0044] It can be understood that the two arc-shaped plates make the entire guide channel an arc-shaped channel, which can prevent the cable from bending during movement, thereby achieving effective protection for the cable.

[0045] According to some embodiments provided by the present invention, the bottoms of the first arc plate 1511 and the second arc plate 1512 are both 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 segment needs to be provided to enable stable movement of the cable. In this embodiment, by providing the limiting portion, after the guide frame 151 rotates to a stable position, it can abut against the main sleeve 11, thereby forming a fixed arc transition segment, which can achieve stable transition of the cable.

[0046] Specifically, a protruding limiting portion is provided at the bottom of the first arc plate 1511 and the second arc plate 1512. The protruding limiting portion can abut against the end surface of the main sleeve 11 after rotating at a predetermined angle, thereby limiting the further rotation of the guide frame 151 and improving its stability.

[0047] According to some embodiments provided by the present invention, a mounting block 154 is provided on each of the first arc plate 1511 and the second arc plate 1512, and a plurality of mounting holes for connecting the tension spring 153 are provided on the mounting block 154 at intervals. The arrangement of the mounting block 154 and the mounting holes can adjust the force applied to the guide frame 151, thereby adjusting the rotation flexibility of the guide frame 151.

[0048] Specifically, a tension spring 153 is provided on the first arc plate 1511 and the second arc plate 1512, one end of the tension spring 153 is connected to the mounting hole, and the other end of the tension spring 153 is extended into the main sleeve 11 for fixed connection. When the tension spring 153 is constant, the mounting hole at the far end will make the tension tighter, that is, the cable needs to apply a greater tension to drive the guide frame 151 to rotate, thereby realizing the adjustment of the rotation flexibility of the guide frame 151.

[0049] It is understandable that the design of the two tension springs 153 can make the force on the guide frame 151 more balanced, which can further improve the stability of the cable when passing through the line and avoid the problem of stress concentration and reduced durability due to uneven force.

[0050] According to some embodiments provided by the present invention, a through slot 111 is provided along the axial direction of the main sleeve 11, and the through slot 111 is connected to the wire passage. The design of the through slot 111 can facilitate the insertion of the cable, thereby realizing rapid insertion of the cable.

[0051] It is understandable that usually both ends of the cable are connected to other devices, for example, one end of the cable is connected to the pipeline robot, and the other end of the cable is connected to the control device, etc., which makes it difficult for the cable to be inserted into the device. In this embodiment, the through slot 111 is designed so that it can be directly inserted into the wire passage inside the main sleeve 11 through the through slot 111.

[0052] According to some embodiments provided by the present invention, both ends of the cable passage are detachably provided with stop blocks 17, a connecting shaft 171 is provided between the stop blocks 17, and the connecting shaft 171 is located in the through slot 111. The setting of the stop blocks 17 can prevent the stuck cable from slipping out of the through slot 111.

[0053] Specifically, the stopper 17 is connected to both ends of the main sleeve 11 and is located at the through slot 111. The connecting shaft 171 passes through the through slot 111, and its two ends are correspondingly connected to the two stopper 17, so that the through slot 111 can be filled by the connecting shaft 171 to prevent the cable inside the main sleeve 11 from being stuck in the through slot 111. The detachable connection of the stopper 17 facilitates the insertion of the cable after disassembly.

[0054] In the specific configuration, the limit block 17 is an arc-shaped limit block 17, which can be detachably connected by bolt connection.

[0055] In some embodiments, one end of the limit block 17 is hinged to the main sleeve 11, and the other end of the limit block 17 is fixedly connected to the main sleeve 11 by a bolt. The hinged connection of one end of the limit block 17 can facilitate the rapid insertion of the cable and the rapid closing of the through slot 111.

[0056] Specifically, the limit block 17 can be rotated along the hinged position by means of a hinge, and the through slot 111 can be opened when rotating, that is, the connecting shaft 171 is flipped to the through slot 111, which can facilitate the insertion of the cable, and after the cable is inserted, the connecting shaft 171 is flipped so that it is located in the through slot 111 to close it. Bolts are used to fasten the limit block 17.

[0057] Specifically, the limit block 17 can be connected and fastened with a captive screw during connection, which can prevent the screw from falling off even if the screw is not tightened during the construction process, thereby preventing the screw from falling off.

[0058] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment uses the guide assembly 15 to guide the cable when the cable passes through, which avoids damage to the cable when the cable follows the pipeline detection robot 50, and can effectively protect the cable at the connection between the branch pipe 30 and the pipeline to be detected 40. Further, the fixed arc transition section formed by the guide frame 151 can avoid bending of the cable when it passes through, thereby achieving effective protection for the cable.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
