Technical Field

[0001] The invention relates to the field of underground pipeline detection, in particular to a detection device for underground pipelines. Background Art

[0002] An underground pipeline detector is a device that can detect the location of buried underground pipelines.

[0003] The current underground pipeline detector is placed on a trolley, and then the trolley is pushed to move the underground pipeline detector so that the underground pipeline detector can find the location of the underground pipeline.

[0004] However, when the trolley encounters an uneven ground, it will shake, and the underground pipeline detector on the trolley is likely to fall to the ground, thereby causing damage to the underground pipeline detector.

[0005] Therefore, in order to solve the above problems, a detection device for underground pipelines is proposed. Summary of the invention

[0007] The technical solution adopted by the present invention to solve its technical problem is: an underground pipeline detection device described in the present invention comprises a cart bottom plate and a detector body; a groove is formed through the surface of the cart bottom plate, the detector body is placed on the cart bottom plate, the top of the detector body is electrically connected to a wire, the other end of the wire is electrically connected to a display screen, fixing rods are fixedly installed on both sides of the detector body, a sliding rod is slidably connected to the fixing rod, a connecting plate is welded to an end of the sliding rod away from the fixing rod, a rectangular plate is fixedly connected to both sides of the connecting plate, a fixing block is fixedly connected to a side of the rectangular plate corresponding to the cart bottom plate, the fixing block is in a "U" shape, a limiting rod is vertically slidably connected to the fixing block, a disc is fixedly connected to the surface of the limiting rod, the bottom end of the disc is fixedly connected to a first spring, and the end of the first spring away from the disc is fixedly connected to the fixing block, by placing the detector body on the cart bottom plate and then pulling the limit When the trolley bottom plate needs to be removed from the trolley bottom plate, the limiting rod is pulled so that the limiting rod no longer contacts the trolley bottom plate, and then the connecting plate is pulled to move the positioning block from the trolley bottom plate, and then the detector body is removed from the trolley bottom plate.

[0008] Preferably, a pressure plate is fixedly installed at the bottom end of the limit rod, and the bottom end of the pressure plate is in contact with the bottom plate of the trolley. When the pressure rod slides downward and is about to contact the bottom plate of the trolley, the pressure plate will contact the bottom plate of the trolley. At this time, the pressure plate will increase the clamping area with the bottom plate of the trolley, thereby achieving the effect of further fixing the detector body.

[0009] Preferably, a sliding groove is provided on one side of the fixed block, and the inner wall of the sliding groove is slidably connected to a limiting block, the limiting block is in an "L" shape, and the horizontal end of the limiting block supports the pressure plate, and the limiting block is made to slide in the sliding groove by sliding the limiting block. At this time, the limiting block will block the pressure plate, and when the pressure plate needs to be moved, the limiting block is pulled so that the limiting block no longer blocks the pressure plate.

[0010] Preferably, the inner wall of the slide groove is fixedly connected to a magnetic block, the surface of the magnetic block is magnetically connected to a limit block, and the limit block is made of iron. By pushing the limit block, the limit block slides in the slide groove, at which time the limit block will contact the magnetic block, and the limit block will be magnetically attracted to the magnetic block, thereby fixing the limit block.

[0011] Preferably, circular grooves are evenly penetrated through the surface of the slide bar, and a connecting block is fixedly connected to the side of the fixing rod corresponding to the slide bar, and a positioning rod is slidably connected to the connecting block, and the positioning rod is engaged with the circular groove. The positioning rod is pulled to make the positioning rod slide out of the circular groove, and then the slide bar is slid so that the slide bar drives the positioning block to move to a suitable position, and then the slide bar is pushed to make the slide bar engage with the circular groove. At this time, the slide bar will be fixed, and then the fixing block and the limit rod are used to clamp the trolley bottom plate, which plays a role in adjusting the position of the fixing block, avoids the positioning block from being unable to adapt to trolley bottom plates of different widths, and improves the use effect of the positioning block.

[0012] Preferably, a second Velcro is fixedly connected to the surface of the positioning rod, a support plate is fixedly installed on the top of the connecting block, and the short arm end of the support plate is fixedly connected to the first Velcro, and the positioning rod is pulled upward, so that the positioning rod drives the second Velcro to slide upward, and then the second Velcro is bonded to the first Velcro, so that the limiting rod is fixed.

[0013] Preferably, a support block is fixedly connected to one side of the fixing rod close to the connecting block, and a second spring is fixedly installed between the support block and the connecting plate. When the limiting rod slides out of the circular groove, the second spring pushes the connecting plate due to the recovery of elastic force, thereby causing the connecting plate to drive the fixing block to move away from the bottom plate of the cart, thereby pushing the connecting plate.

[0015] The present invention is beneficial in that:

[0016] 1. The first spring pushes the limit rod so that the limit rod clamps the cart bottom plate. When the cart moves on a bumpy road, the limit rod and the fixed block clamp the cart bottom plate, thereby preventing the detector body from falling off the cart bottom plate, fixing the detector body and improving the safety of the detector body.

[0017] 2. Pull the positioning rod to make it slide out of the circular groove, then slide the slide bar so that the slide bar drives the positioning block to move to the appropriate position, and then push the slide bar so that the slide bar engages with the circular groove. At this time, the slide bar will be fixed, and then the fixing block and the limit rod are used to clamp the trolley bottom plate, which plays a role in adjusting the position of the fixing block, avoiding the positioning block from being unable to adapt to trolley bottom plates of different widths, and improving the use effect of the positioning block.
