[0029] See also Figure 1-Figure 4 As shown, the utility model is a portable underground pipeline depth measuring instrument, including a frame 1, the frame 1 including a front frame 101 and a rear frame 102, the front frame 101 is hinged to the rear frame 102 through an opening and closing assembly 2, the opening and closing assembly 2 is used to control the opening or closing between the front frame 101 and the rear frame 102, the bottom ends of the front frame 101 and the rear frame 102 are fixedly installed with a rotating support assembly 3, the top end of the rotating support assembly 3 is slidably connected to the detector 5, the opening and closing assembly 2 is rotatably connected to the limit assembly 4, and the limit assembly 4 is used to limit the position of the detector 5.

[0030] During actual use, the frame 1 opens the front frame 101 and the rear frame 102 by activating the opening and closing assembly 2, driving the rotating support assembly 3 at the bottom end of the front frame 101 and the rear frame 102 to rotate around the bottom hinge, so that the top end of the rotating support assembly 3 moves downward, thereby driving the detector 5 hinged at the top end of the rotating support assembly 3 to move downward along the direction limited by the limit assembly 4 to a specific working position, so that the detector 5 can be closer to the ground, thereby improving the accuracy of measurement;

[0031] When closing the device, the frame 1 closes the front frame 101 and the rear frame 102 by activating the opening and closing component 2, driving the rotating support component 3 at the bottom end of the front frame 101 and the rear frame 102 to rotate around the hinge at its bottom end, so that the top end of the rotating support component 3 moves upward, and then drives the detector 5 hinged at the top end of the rotating support component 3 to move upward along the direction limited by the limit component 4 to the inside of the frame 1 to protect the detector 5, while protecting the detector 5, it also saves space.

[0032] In one embodiment, for the above-mentioned opening and closing component 2, the opening and closing component 2 includes a central gear articulated shaft 201, a tooth groove is provided in the middle of the central gear articulated shaft 201, and the central gear articulated shaft 201 is fixedly installed on the side of the top of the front frame body 101 close to the rear frame body 102, and the central gear articulated shaft 201 is used to articulate the front frame body 101 and the rear frame body 102, and a pair of motors 202 are fixedly installed at the bottom end of the rear frame body 102 close to one end of the central gear articulated shaft 201, and the output shafts of the pair of motors 202 are fixedly installed with transmission gears 203, and the transmission gears 203 are engaged with the central gear articulated shaft 201 to drive the opening and closing of the front frame body 101 and the rear frame body 102.

[0033] During actual use, the transmission gear 203 installed on the output shaft is driven to rotate by starting the motor 202. When the transmission gear 203 rotates, it drives the central gear hinge shaft 201 meshed with its surface to rotate, and then the central gear hinge shaft 201 drives the front frame body 101 installed on the outer surface to rotate around the central gear hinge shaft 201, thereby realizing the opening and closing of the front frame body 101 and the rear frame body 102. The opening and closing of the device is driven by the motor, which improves the practicality of the device.

[0034] In one embodiment, for the above-mentioned rotation support assembly, the rotation support assembly 3 includes a plurality of rotation support rods 301, and the rotation support rods 301 are a pair of two in the same direction. A pair of the rotation support rods 301 is fixedly connected by a connecting rod 302 arranged in the middle and a pin rod 303 arranged at one end. A pair of the rotation support rods 301 are installed at the bottom ends of the front frame 101 and the rear frame 102. A slide groove 304 running through the front and back is opened in the middle of the front of the detector 5, and the two pairs of the rotation support rods 301 are slidably installed in the interior of the slide groove 304 through the pin rod 303 fixed at one end.

[0035] During actual use, when the front frame 101 and the rear frame 102 are opened and closed, the rotating support rod 301 is driven to rotate, and then the top end of the rotating support rod 301 is driven to move upward or downward. Since the top end of the rotating support rod 301 is slidably connected to the slide groove 304 in the detector 5 through the pin rod 303, the detector 5 also moves downward or upward, so that the detector 5 can be released or retracted as needed, thereby improving the safety of the detector 5.

[0036] In one embodiment, for the above-mentioned limit assembly, the limit assembly 4 includes an embedded shaft 401, which passes through both ends of the central gear hinge shaft 201 and can rotate freely. The two ends of the embedded shaft 401 are fixedly installed with a limit rod sleeve 402, and the limit rod sleeve 402 is movably connected with a limit rod 403. The bottom end of the limit rod 403 is fixedly connected to the top end of the detector 5, so that the detector 5 can only move up and down along the direction of the limit rod 403.

[0037] During actual use, the embedded shaft 401 can rotate freely in the central gear hinge shaft 201, and the position of the limit rod sleeve 402 to which the embedded shaft 401 is fixed is below the central gear hinge shaft 201. Therefore, the weight of the limit rod sleeve 402 itself will make the limit rod sleeve 402 always in a direction perpendicular to the ground, and then the limit rod 403 movably connected in the limit rod sleeve 402 will also always be perpendicular to the ground. Finally, the detector 5 fixed at the bottom end of the limit rod 403 is always in a direction perpendicular to the ground, thereby improving the stability and reliability of the detector 5.

[0038] In one embodiment, for the above-mentioned frame, one end of the front frame 101 and the rear frame 102 are each provided with a mesh hole 6, and both sides of the front frame 101 and the rear frame 102 are fixedly installed with a guardrail 7, and the bottom ends of the front frame 101 and the rear frame 102 are fixedly installed with a protective plate 8 for protecting the detector 5.

[0039] The utility model is used to protect the detector 5 through the protective railing 7 and the protective plate 8. By providing the mesh holes 6 and using the protective railing 7, the weight of the device is reduced while protecting the detector 5, making the device lighter and easier to carry and transport.

[0040] In one embodiment, for the above-mentioned frame, a push handle 9 is rotatably mounted on one side of the top of the rear frame 102, and buckles 10 are fixedly mounted on one side of the rear frame 102 located at the center of the rotation axis of the push handle 9.

[0041] The utility model switches between the working and transport modes by rotating the push handle 9. When the push handle is open, the user can control the movement of the device by pushing the handle 9, and the push handle 9 can be rotated to a suitable angle through the buckle 10. When closed, the push handle 9 is rotated to the top of the rear frame 102 to reduce the volume and facilitate carrying and transportation.

[0042] In one embodiment, for the above-mentioned frame, a universal wheel 11 is fixedly installed at the bottom end of the frame 1. The utility model can be freely moved through the universal wheel 11, which is convenient for users to use.

[0043] In one embodiment, for the above-mentioned rear frame, a display screen 12 is provided at the top of the rear frame 102. The display screen 12 is connected to the detector 5 via wires. The display screen is located on the upper surface of the rear frame 102 for user convenience.

[0044] In summary, with the aid of the above technical solution of the present invention, the motor 202 fixed to the top of the rear frame 102 is started to drive the transmission gear 203 fixed on the output shaft of the motor 202 to rotate. When the transmission gear 203 rotates, it drives the central gear hinge shaft 201 meshed with the surface thereof to rotate, and then the central gear hinge shaft 201 drives the front frame 101 installed on the outer surface to rotate around the central gear hinge shaft 201, thereby realizing the opening and closing of the front frame 101 and the rear frame 102. When the device is opened, The top of the rotating support rod 301 rotates downward as the front frame 101 and the rear frame 102 open, thereby driving the detector 5 to move downward. At the same time, due to the weight of the limit rod sleeve 402 itself, it can maintain itself perpendicular to the ground by rotating the embedded shaft 401 fixed to itself within the central gear hinge shaft 201, thereby driving the limit rod 403 and the detector 5 perpendicular to the ground, and then rotate the push handle 9 to rotate it to a suitable angle, and then cooperate with the universal wheel 11 at the bottom of the frame 1 to move the device.

[0045] Through the above technical solution, 1. the front frame 101 and the rear frame 102 are driven to open and close by the rotation of the motor 202, and the rotation of the rotating support rod 301 drives the detector 5 to move vertically upward or vertically downward in the limit rod sleeve 402, so that the device can open the front frame 101 and the rear frame 102 when in use, release the detector for work, and close the front frame 101 and the rear frame 102 and retract the detector 5 when not in use, so as to reduce its own volume and facilitate carrying and transportation.

[0046] 2. The detector 5 is driven to move downward to the required height for work or retracted into the interior of the frame 1 by rotating the support rod 301. By retracting the detector 5 into the interior of the frame 1, it is easy to carry and transport, and the detector can also be protected by the mesh holes 6, protective railings 7 and protective plates 8.
