Description

Technical Field

[0001] This invention belongs to the technical field of underground pipeline detection, and specifically relates to an underground pipeline detector with automatic pipeline depth measurement function. Background Technology

[0002] Pipeline detectors can quickly and accurately detect the location, direction, depth, and location and size of damage points in the anti-corrosion layer of underground water pipes, metal pipes, cables, etc., without disturbing the ground cover. They are essential instruments for water companies, gas companies, railway communications, municipal construction, industrial and mining enterprises, and infrastructure units for the renovation, maintenance, and general survey of underground pipelines. With technological advancements, the functions of pipeline detectors have gradually improved. In addition to detecting pipelines, they can also clearly analyze the burial depth of pipelines, providing construction workers with better geological and routing information.

[0003] However, existing underground pipeline detectors have the following drawbacks during use:

[0004] 1. Existing underground pipeline detectors are used in a variety of scenarios in daily use. Therefore, it is unavoidable that some sites have a lot of gravel and other impurities on the ground. When the pipeline detector transmits a detection signal and comes into contact with the underground pipeline and reflects it back, the obstruction of various obstacles increases the interference of the data, which affects the accuracy of the detector's detection data and reduces the quality of the detection data.

[0005] 2. During the detection process, due to the obstruction of ground obstacles, and the fact that the detector needs to detect and analyze the direction of underground pipelines, the equipment needs to be moved on the ground during the detection. Ordinary detectors do not have an obstacle clearing function at the top, which makes the movement of the equipment difficult and makes it very difficult to operate. It requires the staff to make adjustments at any time, which is time-consuming and laborious, increases the difficulty of using the equipment, and reduces the detection efficiency.

[0006] 3. Existing pipeline detectors have many structures at the top, so they are generally large in size. Pipeline detection scenarios are complex, and sometimes it may be necessary to transport the equipment to a designated detection area for detection. During transportation, the detection equipment cannot be disassembled, resulting in a large space occupation, making it inconvenient to store and move, and reducing the convenience of using the device.

[0007] Therefore, it is necessary to invent an underground pipeline detector with automatic pipeline depth measurement function to solve the above problems. Summary of the Invention

A signal receiver is fixedly provided at one end of each of the two mounting brackets. A connecting groove is formed on the inner wall of one end of the mounting cover, and a second motor is installed on the inner wall of the connecting groove.

[0011] Preferably, one end of one of the lead screws passes through the inner wall of the connecting groove and is fixedly connected to the output end of the second motor, and the other ends of both lead screws pass through the inner wall of one side of the mounting cover and are each fixedly provided with a synchronous gear, and a synchronous belt meshes between the outer walls of the two synchronous gears.

[0012] Preferably, the obstacle removal assembly includes support plates fixed to both ends of the mounting cover, with obstacle removal brushes rotatably connected to one side of the bottom of each of the four support plates, and a third motor installed on one side of the top of each of the four support plates. One end of each of the four obstacle removal brushes passes through the top of the four support plates and is fixedly connected to the output end of the four third motors.

[0014] Preferably, a first buffer groove is provided at both ends of the bottom sides of the detection base, and the outer walls of the four support plates are respectively inserted and connected to the inner walls of the four first buffer grooves. A second buffer groove is provided at the middle position of the bottom sides of the detection base, and the outer walls of the two mounting brackets are respectively slidably connected to the inner walls of the two second buffer grooves.

[0015] Preferably, the bottom of the detection base is equipped with four casters, and the outer walls of the detection base are fixed with first handles on both sides. A protective cover is hinged to one side of the top of the detection base, and a through groove is opened on one side of the top of the protective cover.

[0016] Preferably, the quick-release assembly includes a first threaded hole on one side of the top of the fixing frame, the inner wall of the first threaded hole is threaded with a connecting rod, and the outer wall of the connecting rod is wrapped with a support tube.

[0017] Preferably, a control host is installed at one end of the power receiving pole, and a second threaded hole is opened at one end of the control host, and the outer wall of the other end of the power receiving pole is threadedly connected to the inner wall of the second threaded hole.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. This invention, by setting up a leveling mechanism, starts the first and second motors, causing the cleaning roller to rotate. Under the meshing transmission of synchronous gears and synchronous belts, the two lead screws rotate synchronously, carrying the slider to slide in the limiting groove. This, in turn, moves the cleaning roller back and forth at the bottom of the mounting cover, cleaning the ground below the detection base. During the cleaning process, obstacles on the ground are swept to both ends of the mounting cover, making the ground below the mounting cover flat and free of obstacles, greatly reducing the impact of ground obstacles on signal data and improving detection quality. At the same time, the burial depth of the pipeline can be accurately calculated by the transmission time difference between the signal receiver and the signal transmitter.

[0022] 2. By setting up a clearing component, when obstacles at the bottom of the detection base are swept to both sides of the bottom of the equipment by the leveling mechanism, the third motor on the top of the support plate is activated to rotate the clearing brush. The clearing brush drives the obstacles to sweep them and push them to the outer edge of the detection base. During the detection process, no manual cleaning is required from the staff, which facilitates the movement of the equipment, reduces the difficulty of using the equipment, and improves the detection efficiency.

[0023] 3. This invention uses a quick-release assembly to connect the power supply at the upper end of the detection base to the control host via the connection contact of the connecting rod, thereby energizing it and facilitating the operation of the components at the upper end of the detection base. When not in use, the connecting rod can be unscrewed from the fixing frame and the control host respectively, and the detection base, connecting rod and control host can be stored separately. It occupies less space, is easy to transport, and improves the convenience of using the device.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides, for example Figure 1-10 The underground pipeline detector shown includes a detection base 1, and a leveling mechanism 2, a clearing component 3, and a quick-release component 12 are provided on the upper end of the detection base 1.

[0039] The leveling mechanism 2 includes a mounting groove 201 formed on the top of the detection base 1. A mounting cover 202 is slidably connected to the lower end of the inner wall of the mounting groove 201. Limiting grooves 203 are formed on both sides of the inner wall of the mounting cover 202. Sliding blocks 204 are slidably connected to the inner walls of both limiting grooves 203. Mounting cylinders 205 are mounted on one side of each of the two sliding blocks 204. A cleaning roller 206 is rotatably connected between the two mounting cylinders 205. A first motor 207 is mounted on the inner wall of one of the mounting cylinders 205, and one end of the cleaning roller 206 is fixedly connected to the output end of the first motor 207. Lead screws 208 are rotatably connected to the inner walls of both limiting grooves 203, and the outer walls of the two lead screws 208 are threadedly connected to the inner walls of the two sliding blocks 204, respectively. The mounting cover 202... Multiple signal transmitters 209 are installed on the upper side of the inner wall. Mounting brackets 210 are fixed on both sides of the mounting cover 202. A signal receiver 211 is fixed at one end of each mounting bracket 210. A connecting groove 212 is opened on the inner wall of one end of the mounting cover 202. A second motor 213 is installed on the inner wall of the connecting groove 212. When the signal transmitter 209 transmits a signal to detect the pipeline, the cleaning roller 206 is adjusted and moved to the lower side area of ​​the mounting cover 202 so that it does not obstruct the signal transmitter 209. The signal is transmitted through the pipeline by the signal transmitter 209 and received by the signal receiver 211. The burial depth of the pipeline can be accurately calculated by the signal transmission time, which is convenient for the staff to carry out maintenance work later.

[0040] In use, after assembling the device, drag the detection base 1 to move it on the detection ground. Then, lower the mounting cover 202 in the mounting groove 201 so that the cleaning brush 302 and cleaning roller 206 at its bottom both contact the ground. Then, start the first motor 207 and the second motor 213 to make the cleaning roller 206 rotate. Under the meshing transmission of the synchronous gear 214 and the synchronous belt 215, the two lead screws 208 rotate synchronously, causing the slider 204 to slide in the limiting groove 203, thereby moving the cleaning roller 206 back and forth at the bottom of the mounting cover 202. The ground beneath the detection base 1 is cleaned. During the cleaning process, obstacles on the ground are swept to both ends of the mounting cover 202, making the ground beneath the mounting cover 202 flat and free of obstructions. At this time, the signal transmitter 209 is activated to transmit a detection signal to the ground. The detection signal enters the underground without obstruction and senses the pipeline below before being reflected back and received by the signal receiver 211. After receiving, the signal is processed and transmitted to the control host 1204 for analysis. This greatly reduces the impact of ground obstacles on signal data when the detector is detecting pipelines, thus improving the detection quality.

[0041] One end of one lead screw 208 passes through the inner wall of the connecting groove 212 and is fixedly connected to the output end of the second motor 213. The other ends of the two lead screws 208 pass through the inner wall of one side of the mounting cover 202 and are fixedly provided with synchronous gears 214. The outer walls of the two synchronous gears 214 mesh with a synchronous belt 215. By starting the second motor 213 in the connecting groove 212, the lead screws 208 are started synchronously, which move back and forth with the slider 204 and the cleaning roller 206 to clean and level the ground in the detection area.

[0042] Furthermore, as per the instruction manual... Figure 3 As shown, the obstacle clearing assembly 3 includes support plates 301 fixed to both ends of the mounting cover 202. Each of the four support plates 301 has an obstacle clearing brush 302 rotatably connected to one side of its bottom. Each of the four support plates 301 has a third motor 303 installed on one side of its top. One end of each of the four obstacle clearing brushes 302 passes through the top of the four support plates 301 and is fixedly connected to the output end of the four third motors 303. When the obstacle at the bottom of the detection base 1 is swept to both sides of the bottom of the equipment by the leveling mechanism 2, the third motor 303 on the top of the support plate 301 is activated to rotate the obstacle clearing brush 302. The obstacle clearing brush 302 drives the obstacle to sweep it and push it to the outer edge of the detection base 1. During the detection process, no manual cleaning is required, which facilitates the movement of the equipment, reduces the difficulty of using the equipment, and improves the detection efficiency.

[0043] Furthermore, a fixing frame 4 is fixedly installed at the middle position of the upper end of the inner wall of the mounting groove 201. An electric push rod 5 is installed at the bottom of the fixing frame 4, and the output end of the electric push rod 5 is fixedly connected to the top of the mounting cover 202. During the lifting and lowering process of the mounting cover 202, the mounting cover 202 is moved up and down by activating the electric push rod 5.

[0044] The bottom of the detection base 1 has two ends of the first buffer groove 6, and the outer walls of the four support plates 301 are respectively inserted into the inner walls of the four first buffer grooves 6. The bottom of the detection base 1 has two middle positions of the second buffer groove 7, and the outer walls of the two mounting brackets 210 are respectively slidably connected to the inner walls of the two second buffer grooves 7. When the mounting cover 202 moves up and down, the support plates 301 and the mounting brackets 210 on both sides are respectively inserted into the first buffer groove 6 and the second buffer groove 7 so that they are not obstructed.

[0045] Furthermore, four movable wheels 8 are installed at the bottom of the detection base 1, and first handles 9 are fixed on both sides of the outer wall of the detection base 1. A protective cover 10 is hinged to one side of the top of the detection base 1, and a through groove 11 is opened on one side of the top of the protective cover 10. The detection base 1 moves by means of the movable wheels 8.

[0046] Furthermore, the quick-release assembly 12 includes a first threaded hole 1201 on one side of the top of the mounting bracket 4. The inner wall of the first threaded hole 1201 is threaded with a connecting rod 1202. The outer wall of the connecting rod 1202 is wrapped with a support tube 1203. In use, the connecting rod 1202 is screwed into the first threaded hole 1201 on one side of the mounting bracket 4, and then the protective cover 10 is put on, so that the support tube 1203 is inserted in the through groove 11, which can protect the top of the equipment without obstructing the quick-release assembly 12.

[0047] A control host 1204 is installed at one end of the connecting rod 1202. A second threaded hole 1205 is opened at one end of the control host 1204, and the outer wall of the other end of the connecting rod 1202 is threadedly connected to the inner wall of the second threaded hole 1205. When in use, after the connecting rod 1202 is screwed onto the fixing frame 4, the control host 1204 is threadedly connected to the other end of the connecting rod 1202 through the second threaded hole 1205. At this time, the power supply at the upper end of the detection base 1 is connected to the control host 1204 through the connection contact of the connecting rod 1202, thereby energizing it and facilitating the operation of the components at the upper end of the detection base 1. When not in use, the connecting rod 1202 is unscrewed from the fixing frame 4 and the control host 1204 respectively, and the detection base 1, the connecting rod 1202 and the control host 1204 are stored separately. It occupies less space, is easy to transport, and improves the convenience of using the device.

[0048] Furthermore, a control panel 13 is installed on the top of the control host 1204, and a second handle 14 is installed on the other end of the control host 1204. The control panel 13 facilitates the control of the entire device, while the first handle 9 and the second handle 14 facilitate the operation and handling of the device.
