Technical Field

[0001] The utility model relates to the technical field of underground pipeline detection instruments, in particular to a disassembly and assembly structure and an underground pipeline detection device. Background Art

[0002] Underground pipelines are ubiquitous in urban construction and are categorized by their intended use. For example, some are primarily used to circulate domestic water, while others are used to route cables for electricity. When an underground pipeline malfunctions, manual access is required for repair. Because underground pipelines are often complex, workers must use relevant detection equipment to ensure they are safe before entering.

[0003] The prior art with announcement number CN205343107U discloses an automatic underwater pipeline detection device, including walking wheels, a drive motor, an electric telescopic rod, a rotating motor, a frame, a controller and a camera. The rotating motor is installed on both sides of the frame, the electric telescopic rod is installed on the rotating motor, the drive motor is installed on the electric telescopic rod, the walking wheels are installed on the shaft of the drive motor, the controller is installed on the upper part of the frame, and the camera is installed on the lower part; two pairs of rotating motors are installed on both sides of the frame; the frame is a rectangular structure; the controller is connected to the drive motor, the rotating motor and the camera through wires; the drive motor and the rotating motor are water discharge structures.

[0004] However, the existing detection device still has defects. For example, the camera is fixedly connected to the frame and cannot be removed from the frame. When other detection of underground pipelines is required, such as ultrasonic detection, an additional detection device with an ultrasonic probe is required, which is not only costly but also inconvenient to use. Utility Model Content

[0005] The purpose of the present invention is to overcome the above technical deficiencies and propose a disassembly and assembly structure and an underground pipeline detection device to solve the technical problem in the prior art that the camera of the detection device is fixedly connected to the frame and cannot be disassembled from the frame to replace other detection heads, which is inconvenient to use.

[0006] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0007] The utility model provides a disassembly and assembly structure, comprising:

[0008] The fixed cylinder is provided with a receiving cavity for accommodating the detection head.

[0009] a clamping block, slidably connected to the fixing cylinder; and

[0010] An adjusting member is slidably connected to the outer wall of the fixed cylinder, and the adjusting member is provided with an avoidance groove. When sliding, the adjusting member can drive the avoidance groove to align or misalign with the blocking block. When the avoidance groove and the blocking block are misaligned, the adjusting member can drive the blocking block to engage the detection head of the accommodating cavity; when the avoidance groove and the blocking block are aligned, the blocking block can slide into the avoidance groove to detach the detection head from the accommodating cavity.

[0011] In some embodiments, a through-groove is provided on the side of the fixed cylinder, the groove being connected to the accommodating cavity, the clamping block being located in the groove and being able to slide along the groove into the accommodating cavity to engage the detection head, or the clamping block being able to slide out of the accommodating cavity to detach from the detection head.

[0012] In some embodiments, the sliding groove penetrates the outer wall of the fixing cylinder to form an inlet and outlet on the wall of the accommodating cavity, the clamping block is spherical, and the diameter of the clamping block is larger than the diameter of the inlet and outlet.

[0013] In some embodiments, there are multiple slide grooves and multiple blocks, and multiple slide grooves are arranged along the circumference of the fixed cylinder. Each block is corresponding to the slide groove, and the adjusting member is annular. When sliding, the adjusting member can simultaneously drive multiple blocks to slide into the accommodating cavity and be clamped to the detection head.

[0014] In some embodiments, the avoidance groove is annular, and the adjusting member can drive the avoidance groove to align with multiple blocks at the same time when sliding, and multiple blocks can slide into the avoidance groove under the action of the detection head.

[0015] In some embodiments, the disassembly and assembly structure also includes an elastic member, which connects the fixed cylinder and the adjusting member. When the adjusting member slides to drive the avoidance groove to align with the blocking block, the adjusting member presses against the elastic member to accumulate elastic force; the elastic member can also release the elastic force to drive the adjusting member to slide and reset, so that the avoidance groove and the blocking block are misaligned.

[0016] In some embodiments, a limiting ring is sleeved on the outer wall of the fixing tube. When the elastic member releases the elastic force to drive the adjusting member to reset, the adjusting member abuts against the limiting ring.

[0017] The utility model also provides an underground pipeline detection device, including a detection head, a manipulator assembly and the above-mentioned disassembly and assembly structure, the fixed cylinder of the disassembly and assembly structure is connected to the manipulator assembly, and the accommodating cavity of the disassembly and assembly structure is detachable and plugged into the detection head.

[0018] In some embodiments, the manipulator assembly includes a first rotating arm, a second rotating arm, a third rotating arm, and a fourth rotating arm that are rotatably connected in sequence end to end, and the fourth rotating arm is rotatably connected to the fixed cylinder.

[0019] In some embodiments, the rotation direction of the second rotating arm, the rotation direction of the third rotating arm, and the rotation direction of the fourth rotating arm are perpendicular to each other.

[0020] Compared with the prior art, the disassembly and assembly structure provided by the present invention includes a housing chamber provided in a fixed cylinder that can be used to accommodate a detection head. The adjusting member can be first slid to the avoidance groove and aligned with the card block, the detection head can be inserted into the housing chamber, and then the adjusting member can be slid to dislocate the avoidance groove and the card block. The adjusting member drives the card block to engage with the detection head, thereby locking the detection head. When the detection head needs to be disassembled, the adjusting member can be slid to the avoidance groove and aligned with the card block, and then the detection head can be pulled out of the housing chamber. The detection head can drive the card block into the avoidance groove, and the detection head can continue to move until it is completely pulled out of the housing chamber. It can be seen that the present invention only needs to control the reciprocating sliding of the adjusting member to disassemble and replace the detection head, which saves time and effort and is easy to use.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] In order to solve the technical problem in the prior art that the camera of the detection device is fixedly connected to the frame and cannot be removed from the frame to replace other detection heads, which is inconvenient to use, the utility model provides a disassembly and assembly structure that can realize the rapid replacement of the detection head without the need for additional configuration of a device with a detection head, thereby saving costs and being easy to use.

[0028] It should be noted that the disassembly and assembly structure described in the present invention is used for but not limited to underground pipeline detection devices, etc. For the convenience of explanation, in the present invention, only the disassembly and assembly structure applied to underground pipeline detection devices is used as an example for explanation, and the principle of applying the disassembly and assembly structure to other types of equipment is essentially the same as the principle applied to underground pipeline detection devices, so they will not be repeated here.

[0029] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the disassembly and assembly structure 100 in one embodiment of the present invention. The disassembly and assembly structure 100 includes a fixed cylinder 1, a block 2 and an adjusting member 3. The fixed cylinder 1 is provided with a receiving cavity 11 for accommodating the detection head. The block 2 is slidably connected to the fixed cylinder 1. The adjusting member 3 is slidably connected to the outer wall of the fixed cylinder 1. The adjusting member 3 is provided with an avoidance groove 31. When the adjusting member 3 slides, it can drive the avoidance groove 31 to align or misalign with the block 2. When the avoidance groove 31 is misaligned with the block 2 ( Figure 2 As shown, the adjusting member 3 can drive the block 2 to engage the detection head 4 in the accommodating cavity 11 and the adjusting member 3 can limit the block 2, restricting the block 2 from moving toward the adjusting member 3, so that the block 2 can stably engage the detection head 4. When the avoidance groove 31 is aligned with the block 2 ( Figure 3 (see Figure 3), the locking block 2 can slide into the avoidance groove 31 to disengage the detection head 4 from the accommodating chamber 11, thereby unlocking the detection head 4. The detection head 4 can now be smoothly withdrawn from the accommodating chamber 11, completing the removal process. Thus, during the process of removing and assembling the detection head 4, it is only necessary to control the reciprocating sliding of the adjustment member 3, making the removal and assembly quick and convenient.

[0030] In this embodiment, the alignment of the avoidance groove 31 and the card block 2 can be understood as the position of the avoidance groove 31 completely corresponding to the card block 2. At this time, the card block 2 can slide into the avoidance groove 31 and exit the accommodating chamber 11. The misalignment of the avoidance groove 31 and the card block 2 can be understood as the position of the avoidance groove 31 is completely misaligned with the card block 2. At this time, the adjustment member 3 has a limiting effect on the card block 2, restricting the card block 2 from moving. A part of the card block 2 is located in the accommodating chamber 11 and is stably engaged with the detection head 4 to lock the detection head 4. The detection head 4 can be stably connected to the fixed cylinder 1. Specifically, a card slot 41 is provided on the outer wall of the detection head 4. The card block 2 can be engaged with the card slot 41 when entering the accommodating chamber 11, thereby locking the detection head 4.

[0031] When the detection head 4 needs to be unlocked and disassembled, the adjustment member 3 can be slid to Figure 3In the position shown, the avoidance groove 31 of the adjusting member 3 is aligned with the block 2, and the block 2 has a sliding space. At this time, a pulling force can be applied to the detection head 4. The oblique side wall of the groove 41 of the detection head 4 presses the block 2, driving the block 2 to slide into the avoidance groove 31, the block 2 disengages from the groove 41, and the detection head 4 is unlocked. At this time, the detection head 4 can be smoothly pulled out of the accommodating cavity 11 to complete the disassembly.

[0032] In one embodiment, see Figure 4 A through-groove 12 is formed on the side of the fixed cylinder 1 and connects to the accommodating chamber 11. The clamping block 2 is located in the groove 12 and can slide along the groove 12 to extend into the accommodating chamber 11 to engage the detection head 4, or slide out of the accommodating chamber 11 to disengage the detection head 4 and unlock the detection head 4. In this embodiment, the fixed cylinder 1 is cylindrical in shape. The clamping block 2 can slide toward the accommodating chamber 11 to engage the detection head 4 in the accommodating chamber 11; the clamping block 2 can slide toward the adjusting member 3 to disengage the detection head 4 and unlock the detection head 4.

[0033] Furthermore, the chute 12 penetrates the outer wall of the fixed cylinder 1 to form an inlet and outlet 13 in the wall of the accommodating chamber 11. The clamping block 2 is spherical, which can be understood as a ball, and the diameter of the clamping block 2 is larger than the diameter of the inlet and outlet 13 to prevent the clamping block 2 from escaping from the fixed cylinder 1 through the inlet and outlet 13 and causing loss. A portion of the clamping block 2 can pass through the inlet and outlet 13 and enter the accommodating chamber 11. The portion of the clamping block 2 that enters the accommodating chamber 11 can engage with the clamping groove 41 of the detection head 4 to lock the detection head 4.

[0034] In one embodiment, see Figure 2 and Figure 4 There are multiple slide grooves 12 and multiple blocks 2. Multiple slide grooves 12 are arranged along the circumference of the fixed cylinder 1. Each block 2 is correspondingly arranged in the slide groove 12. The adjusting member 3 and the card groove 41 of the detection head 4 are both annular. The avoidance groove 31 on the inner wall of the adjusting member 3 is also annular and is slidably sleeved on the outer wall of the fixed cylinder 1. When sliding, the adjusting member 3 can simultaneously drive multiple blocks 2 to slide into the accommodating cavity 11 and be clamped in the card groove 41 of the detection head 4. Multiple blocks 2 are clamped to the detection head 4 from multiple directions at the same time, which can make the connection of the detection head 4 more stable. In addition, when the detection head 4 needs to be disassembled, the adjusting member 3 can be slid to the position where the avoidance groove 31 is aligned with the block 2, and then the detection head 4 can be pulled out. The inclined wall of the card groove 41 of the detection head 4 can simultaneously drive multiple blocks 2 to slide into the avoidance groove 31 at the same time, and the detection head 4 can be pulled out.

[0035] In one embodiment, see Figure 2 and Figure 3The disassembly and assembly structure 100 also includes an elastic member 5, which connects the fixed cylinder 1 and the adjusting member 3. When the detection head 4 needs to be disassembled, an external force can be applied to the adjusting member 3 to drive it to slide. When the adjusting member 3 slides to drive the avoidance groove 31 to align with the block 2, the adjusting member 3 presses against the elastic member 5 to accumulate elastic force. After the detection head 4 is pulled out, the adjusting member 3 is released and the external force applied to the adjusting member 3 is canceled. At this time, the elastic member 5 releases the elastic force to drive the adjusting member 3 to slide back to the original position, so that the avoidance groove 31 is misaligned with the block 2. When the detection head 4 is installed again, the adjusting member 3 can be slid to drive the avoidance groove 31 to align with the block 2, and the detection head 4 can be inserted into the accommodating cavity 11. The adjusting member 3 is released, and the adjusting member 3 slides to drive the block 2 to engage the slot 41 of the detection head 4, locking the detection head 4. Since the elastic member 5 has an elastic force on the adjusting member 3, in a natural state, the elastic member 5 can prevent the adjusting member 3 from accidentally sliding and unlocking the detection head 4, so that the detection head 4 is stably installed.

[0036] In one embodiment, see Figure 2 The outer wall of the fixed tube 1 is sleeved with a limit ring 6. When the elastic member 5 releases its elastic force to drive the adjusting member 3 to return to its original position, the adjusting member 3 abuts against the limit ring 6. In this embodiment, the limit ring 6 can be made of a rubber ring, which not only limits the adjusting member 3 to prevent it from separating from the fixed tube 1, but also provides a certain cushioning effect on the adjusting member 3.

[0037] See also Figure 5 The present invention also provides an underground pipeline detection device 101, comprising a manipulator assembly 7, the aforementioned disassembly and assembly structure 100, and a detection head 4. The fixing tube 1 of the disassembly and assembly structure 100 is connected to the manipulator assembly 7, and the accommodating chamber 11 of the disassembly and assembly structure 100 is removably plugged into the detection head 4. The manipulator assembly 7 is removably connected to the detection head 4 via the disassembly and assembly structure 100. The manipulator assembly 7 can drive the detection head 4 to move in three dimensions, enabling the detection head 4 to detect in multiple directions and move over a large range, thereby facilitating detection.

[0038] In one embodiment, see Figure 5 The manipulator assembly 7 includes a first rotating arm 71, a second rotating arm 72, a third rotating arm 73, and a fourth rotating arm 74, which are rotatably connected end to end. The fourth rotating arm 74 is rotatably connected to the fixed cylinder 1. In this embodiment, the position of the detection head 4 can be adjusted by controlling the rotation of at least one of the second rotating arm 72, the third rotating arm 73, and the fourth rotating arm 74. This multi-jointed arm rotation allows the detection head 4 to have a wide range of motion.

[0039] In one embodiment, see Figure 5 The rotation direction of the second rotating arm 72, the rotation direction of the third rotating arm 73 and the rotation direction of the fourth rotating arm 74 are all perpendicular to each other, so that the movement of the detection head 4 is more flexible and the movement space is larger.

[0040] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0041] The underground pipeline detection device 101 of the present invention allows for quick assembly and disassembly of the detection head 4 simply by sliding the adjustment member 3, saving time and effort and facilitating ease of use. The detection head 4 can be replaced as needed. For example, the detection head 4 can be a camera to capture the actual conditions inside the underground pipeline, facilitating pre-planning of detection routes. Alternatively, the detection head can be an ultrasonic detector to detect the distance to obstacles, facilitating the implementation of protective measures.

[0042] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
