Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and particularly to a GPR shallow pipeline detection device with a protection structure. Background Technique

[0002] With the development and progress of society, people's living standards have been greatly improved, and there are also higher requirements for roads with longer service years. Coupled with safety considerations for electricity and gas use, it is necessary to renovate and transform them; therefore, it is necessary to detect the pipelines under some roads.

[0003] A GPR shallow pipeline detection device disclosed in the existing patent (publication number: CN214151048U) drives the storage shaft to rotate by pulling the rainproof cloth from the baffle, pulls out the rainproof cloth through the top groove, and then passes through the support rod of the vehicle frame, and is clamped by the hook and the clamping ring. At this time, the rainproof cloth plays a role in shielding the GPR ground penetrating radar, facilitating the use of the device in rainy days.

[0004] However, the above technical solution still has certain defects. When it rains, the staff needs to manually pull out the rainproof cloth to cover the detection radar, which is labor-consuming and time-consuming, thus reducing the operation efficiency. At the same time, when detecting, the device will generate a certain vibration when moving on the ground, which easily causes the detection radar to be collided during operation, resulting in damage to the precision components inside the detection radar, and further causing errors during the detection process. For this reason, a GPR shallow pipeline detection device with a protection structure is proposed. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a GPR shallow pipeline detection device with a protection structure to solve the technical problems raised in the above background.

A threaded screw rod is rotatably connected to one side of the clamping plate, and a square plate is rotatably connected to the middle of the surface of the threaded screw rod.

[0009] As a preferred technical solution, two sets of moving wheels are installed on both sides of the vehicle floor. A long shaft is fixedly connected between the moving wheels. A storage battery is installed on one side of the top end of the vehicle floor. A generator is electrically connected to one side of the storage battery.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0027] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0028] A GPR shallow pipeline detection device with a protective structure, as Figures 1-5 shown, which includes a vehicle plate 100. One side of the top of the vehicle plate 100 is provided with a covering component 200, and the middle of the top of the vehicle plate 100 is provided with a protection component 300;

[0029] The covering component 200 includes a winding box 210 fixed to one side of the top of the vehicle plate 100. A winding shaft 220 is rotatably connected inside the winding box 210. A shielding cloth 230 is wound on the surface of the winding shaft 220. Both the front and back sides of one end of the shielding cloth 230 are fixed with connecting plates 231. A conveyor belt 240 is provided on the side of the two connecting plates 231 away from the shielding cloth 230. Pulley wheels 250 are rotatably connected to both sides of the inner wall of the conveyor belt 240. One end of a group of pulley wheels 250 is fixed with a connecting shaft 260. A belt 270 is rotatably connected to the surface of the connecting shaft 260. A pressing roller 280 is attached to the bottom end of the inner wall of the conveyor belt 240. One end of the pressing roller 280 is provided with a fixing block 290. A cross plate 2910 is welded to the end of the fixing block 290 away from the pressing roller 280. A spring telescopic rod 2920 is provided at the bottom end of the cross plate 2910, and an L-shaped connecting plate 2930 is fixed to one side of the cross plate 2910;

[0030] The protection component 300 includes piston cylinders 310 fixed to the front and back sides inside the vehicle plate 100. A piston rod 320 is slidably connected to the inner wall of the piston cylinder 310. A return spring 330 is sleeved on the surface of the piston rod 320, and a first inclined block 340 is fixed to the top end of the piston rod 320. A second inclined block 350 is provided on one side of the first inclined block 340 and is matched with it. A connecting pipe 360 is provided on one side of the piston cylinder 310. One end of the connecting pipe 360 away from the piston cylinder 310 is connected to a protection airbag 370. A right-angle block 351 is fixed to one side of the second inclined block 350. A clamping plate 380 is fixed to the end of the right-angle block 351 away from the second inclined block 350. A threaded lead screw 390 is rotatably connected to one side of the clamping plate 380. A square plate 3910 is rotatably connected to the middle of the surface of the threaded lead screw 390.

[0031] The staff places the detection radar 170 into the placement groove 101, then rotates the turntable 391 to drive the threaded lead screw 390 to rotate, causing the threaded lead screw 390 to push the clamping plate 380 to move until the two sides of the detection radar 170 are fixed. While the clamping plate 380 moves, it drives the second inclined block 350 to move synchronously through the right-angle block 351, causing the second inclined block 350 to abut against and squeeze the first inclined block 340, so that the first inclined block 340 drives the piston rod 320 to stretch the return spring 330 and compress the gas inside the piston cylinder 310. The gas enters the protective airbag 370 through the connecting pipe 360 and causes it to expand, which can effectively prevent the detection radar 170 from being collided or squeezed during movement or operation, thereby protecting the precision components of the detection radar 170 from damage. At the same time, the protective airbag 370 has a certain buffering effect, which can absorb part of the vibration energy, further reduce the error during measurement, and improve the operation efficiency. The device is moved by pulling the vehicle frame 110 to detect the shallow pipelines. When it rains, the staff presses down the L-shaped connecting plate 2930, causing the L-shaped connecting plate 2930 to drive the cross plate 2910 to descend and compress the spring telescopic rod 2920. At the same time, the cross plate 2910 drives the pressing roller 280 to descend synchronously through the fixing blocks 290 on both sides, making the pressing roller 280 closely adhere to the inner wall of the conveyor belt 240, tightening the conveyor belt 240. At this time, the rotation of the moving wheel 120 drives the belt 270 to rotate synchronously through the long shaft 130, causing the belt 270 to drive the connecting shaft 260 to rotate. The connecting shaft 260 drives the pulley 250 to rotate synchronously. The conveyor belt 240 can effectively drive the connecting plate 231 to move through the rotation of the pulley 250, causing the connecting plate 231 to drive the shielding cloth 230 to move along the conveyor belt 240, so that the shielding cloth 230 covers the detection radar 170 and the generator 150, preventing rainwater from directly contacting and eroding the radar device detection radar 170, thereby extending the service life of the radar. At the same time, through the automatic covering of the shielding cloth 230, manpower and time are saved, the operation efficiency is improved, the operation personnel are prevented from being exposed in the rain due to frequent manual covering of the radar, and the safety hazards caused by weather reasons are reduced.

[0032] Please refer specifically to Figure 1 On both sides of the vehicle board 100, two groups of moving wheels 120 are installed. A long shaft 130 is fixedly connected between the moving wheels 120. On one side of the top of the vehicle board 100, a storage battery 140 is installed. One side of the storage battery 140 is electrically connected to a generator 150. The output end of the generator 150 is rotationally connected to the long shaft 130 through a transmission belt 160. On both sides of the top of the vehicle board 100, vehicle frames 110 are fixed, and a placement groove 101 is opened in the middle of the top of the vehicle board 100. A detection radar 170 is installed in the placement groove 101. A display screen 180 is installed on the vehicle frame 110.

[0033] The staff member pulls the vehicle frame 110 to rotate the moving wheels 120, moving the device and detecting the pipeline through the detection radar 170. When the moving wheels 120 rotate, the generator 150 operates by driving the conveyor belt 160 through the long shaft 130. The generator 150 can charge the battery 140, enabling the detection radar 170 to work for a long time, and the detected data can be displayed on the display screen 180 in real time for easy observation.

[0034] Please refer specifically to Figure 1 、 Figure 3 and Figure 4 ,A guide rod 241 for the smooth sliding of the shielding cloth 230 is provided between the two sets of vehicle frames 110. One end of the inner wall of the belt 270 away from the connecting shaft 260 is rotatably connected to the long shaft 130. The bottom end of the spring telescopic rod 2920 is fixed to the top end of the vehicle board 100. One end of the L-shaped connecting plate 2930 extends to one side of the vehicle frame 110.

[0035] By setting the guide rod 241, the shielding cloth 230 can move more stably. By setting one end of the L-shaped connecting plate 2930 on one side of the vehicle frame 110, it is convenient for the staff to press it.

[0036] Please refer specifically to Figure 2 and Figure 5 ,The protective airbag 370 is arranged on the side wall of the placement groove 101. The top end of the piston cylinder 310 is at the same horizontal plane as the top end of the vehicle board 100. Clamping plates 380 are arranged on the front and back sides of the detection radar 170. A turntable 391 is installed on the side of the threaded lead screw 390 away from the clamping plate 380.

[0037] The protective airbag 370 can protect the periphery of the detection radar 170. By setting the clamping plates 380, the detection radar 170 can be fixed better.

[0038] During use, the staff place the detection radar 170 into the placement groove 101, and then rotate the turntable 391 to drive the threaded lead screw 390 to rotate, so that the threaded lead screw 390 pushes the clamping plate 380 to move until the two sides of the detection radar 170 are fixed. At the same time, gas enters the protective airbag 370 through the connecting pipe 360 and makes it expand, which can effectively prevent the detection radar 170 from being collided or squeezed during movement or operation, thereby protecting the precision components of the detection radar 170 from damage. At the same time, the protective airbag 370 has a certain buffering effect and can absorb part of the vibration energy, further reducing the error during the measurement process and improving the operation efficiency. By pressing down the L-shaped connecting plate 2930, the L-shaped connecting plate 2930 drives the cross plate 2910 to descend and compress the spring telescopic rod 2920. At the same time, the cross plate 2910 drives the pressing roller 280 to descend synchronously through the fixing blocks 290 on both sides, so that the pressing roller 280 is closely attached to the inner wall of the conveyor belt 240, making the conveyor belt 240 tense. The conveyor belt 240 can effectively drive the connecting plate 231 to move through the rotation of the pulley 250, so that the connecting plate 231 drives the shielding cloth 230 to move along the conveyor belt 240, and the shielding cloth 230 covers the detection radar 170 and the generator 150, preventing rainwater from directly contacting and eroding the radar device detection radar 170, thereby extending the service life of the radar. At the same time, through the automatic covering of the shielding cloth 230, manpower and time are saved, the operation efficiency is improved, the operators are prevented from being exposed to the rain due to frequent manual covering of the radar, and the safety hazards caused by weather reasons are reduced. The parts not involved in this device are the same as the prior art or can be implemented using the prior art.

[0039] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations on the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
