Description

[0002] Underground pipelines are important infrastructure in cities.

[0041] An underground pipeline detector provided by the present invention is now described.

[0042] Please also read Figures 1 to 5 The present invention provides an underground pipeline detector, which includes not only a detection vehicle body 1, but also a marking unit 2, a cleaning component 7 and an azimuth adjustment component 8; the marking unit 2 is fixedly mounted on the detection vehicle body 1, and the marking unit is used to mark the direction of the underground pipeline; the marking unit 2 includes a paint stirring unit, a hose 24 and a coating nozzle 23, the coating nozzle 23 is connected to the paint stirring unit through the hose 24, and the coating nozzle 23 is arranged at the bottom of the detection vehicle body 1; the azimuth adjustment component 8 includes a plurality of springs 81, a disc 82 and a ball 83; a plurality of the springs 81 are vertically arranged below the detection vehicle body 1; the disc 82 is a hollow structure, fixedly mounted at the tail end of the spring 81, a plurality of the springs 81 are arranged in an array along the circumferential direction of the disc 82, and a through hole 821 is provided at the bottom of the disc 82; the ball 83 is rolled in the disc 82, and the diameter of the ball 83 is larger than the diameter of the through hole 821;

[0043] The hose 24 is inserted into the ball 83 , and the end of the hose 24 penetrates the disc 82 . The end of the hose 24 is connected to the coating nozzle 23 .

[0044] The present embodiment provides an underground pipeline detector. Compared with the prior art, when the detection vehicle 1 vibrates, the connection between the disc 82 and the detection vehicle 1 is connected through multiple springs 81. The setting of the spring 81 can effectively reduce the vibration impact on the coating nozzle 23. At the same time, multiple springs 81 are arrayed around the disc 82, and there are balls 83 inside the disc 82. When the detection vehicle 1 deviates, the balls 83 roll in the disc 82. At the same time, due to the setting of the spring 81, when the balls 83 are pressed down to one side, the spring 81 on the side is stretched by force, and the spring 81 on the corresponding side is squeezed upward, causing the spring 81 on the corresponding side to shorten. Finally, the disc 82 is dynamically adjusted under the elastic action of the spring 81 itself, so as to avoid shaking and causing damage to the coating nozzle 23 and offset of the marking position during the spraying operation of the detected pipeline direction on the ground.

[0045] On the basis of the above-mentioned embodiment, the underground pipeline detector also includes a fixed plate 3, a fixed frame 4, a reciprocating screw 5 and a driving motor 6; the fixed plate 3 is arranged at the front end of the detection vehicle body 1, and the fixed plate 3 is fixedly connected to the detection vehicle body 1; the fixed frame 4 is fixedly arranged on the fixed plate 3, a hollow cavity 41 is arranged in the fixed frame 4, and a groove 42 is arranged at the bottom of the hollow cavity 41, and the hollow cavity 41 is connected to the outside through the groove 42; a reciprocating screw 5 is arranged inside the hollow cavity 41, and the central axis of the reciprocating screw 5 is arranged along the width direction of the detection vehicle body 1, one end of the reciprocating screw 5 is connected to the power output end of the driving motor 6, and the reciprocating screw 5 is rotatably connected to the fixed frame 4; the cleaning component 7 is arranged on the reciprocating screw 5, and the cleaning component 7 is threadedly connected to the reciprocating screw 5.

[0046] The present invention first starts the driving motor 6, and the driving motor 6 drives the reciprocating screw 5 to rotate. Since the cleaning component 7 is threadedly connected to the reciprocating screw 5, the cleaning component 7 reciprocates along the width direction of the detection vehicle body 1 under the rotation of the reciprocating screw 5, thereby driving the cleaning component 7 to clean stones and the like in the forward direction of the underground pipeline detector, so as to prevent the staff from ignoring obstacles in the forward direction on the ground and causing damage to the device; at the same time, the present invention is also provided with a marking unit 2, so as to realize the detection of the direction of the underground pipeline while spraying the direction of the pipeline after detection on the ground, saving working time and improving work efficiency.

[0047] Furthermore, it also includes a bearing seat, which is arranged in the hollow cavity 41, and the reciprocating screw 5 is connected to the bearing seat through a ball 83 nut pair.

[0048] The use of the ball 83 nut pair connection can reduce friction and make the reciprocating screw 5 more stable and smooth during rotation.

[0049] See also Figure 2 and Figure 3 In some embodiments, the cleaning assembly 7 includes a limiting rod 71, a connecting rod 72 and two cleaning plates 73.

[0050] The two cleaning plates 73 are respectively arranged on both sides of the connecting plate to clean the stones on the ground during the reciprocating motion, avoiding the situation where only one side can clean the stones on the ground. At the same time, the two cleaning plates 73 are arranged at an angle to divert the stones on the ground during the forward movement of the detection vehicle 1, avoiding direct impact on the detection vehicle 1 to affect the forward speed of the detection vehicle 1.

[0051] Furthermore, a baffle 74 is provided at the rear end of the cleaning plate 73 and is arranged along the width direction of the detection vehicle body 1 ; the baffle 74 is arranged to prevent stones from impacting the detection vehicle body 1 , thereby providing secondary protection for the detection vehicle body 1 .

[0052] Furthermore, an alarm is provided on the detection vehicle body 1 and a sensor is provided on the outer facade of the cleaning plate 73.

[0054] The stirring motor is started, and the stirring motor drives the stirring drum 22 to rotate. Since the paint is placed in the stirring drum 22, the paint is stirred evenly when the stirring drum 22 rotates. The evenly stirred paint passes through the tail end of the stirring drum 22 and enters the coating nozzle 23, and is finally sprayed on the ground through the coating nozzle 23 to mark and locate the direction and position of the excavated pipeline after detection, so as to facilitate the later staff to dig along the sprayed paint.

[0055] Furthermore, a stirring shaft is provided inside the stirring drum 22 , and a plurality of stirring blades are fixedly provided on the outer circumference of the stirring shaft. The plurality of stirring blades are arranged at intervals along the circumference of the stirring shaft.

Therefore, the paint in the stirring drum 22 is mixed more evenly under the joint action of the stirring blades and the stirring shaft, thereby achieving the best coating effect and avoiding large particles in the paint clogging the coating nozzle 23 when marking and positioning the ground, thereby affecting the coating marking effect.

[0057] On the basis of the above embodiment, the stirring blade is arranged in a spiral shape, which facilitates the stirring of the paint and avoids large particles in the paint from clogging the coating nozzle and affecting the use of the coating nozzle.
