DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 — Figure 5 As shown, the embodiment of the utility model proposes an underground pipeline detector for engineering investigation, which includes: a receiver and a transmitter 1, the upper surface of the transmitter 1 is fixedly connected with a battery base 2 and a base 4, the battery base 2 and the base are arranged on both sides of the upper surface of the transmitter 1, the upper surface of the base 4 is fixedly connected with a handle 3, the end of the handle 3 away from the base 4 is fixedly connected to a side of the battery base 2 close to the base 4, the upper surface of the battery base 2 is fixedly connected with an operation screen 5 and electrically connected, the upper surface of the battery base 2 is fixedly connected with a No. 1 rotating shaft 7 at one end away from the base 4, the No. 1 rotating shaft 7 is rotatably connected with a protective cover 6, and the transmitter 1 is fixedly connected with a battery base 2. Two springs 11 are fixedly connected to the side of the transmitter 1, and a card block 10 is fixedly connected to one end of the spring 11 away from the transmitter 1. The two springs 11 are arranged at both ends of the side of the transmitter 1. The transmitter 1 is provided with two fixing plates 8 fixedly connected to one side of the spring 11. The fixing plates 8 are vertically arranged below the spring 11. The two fixing plates 8 are rotatably connected to a snap plate 9 through a rotating rod provided in the middle. By providing a receiver placement slot on the side of the transmitter 1, the receiver can be placed therein when storing and taking, and can be taken out for use when in use, which is convenient for storage and taking, and will not cause signal influence during use.

[0023] The receiver includes a receiver middle plate 12, the upper and lower ends of which are respectively rotated by a second rotating shaft 15 and electrically connected to a display screen 14 and a receiver bottom plate 13. By setting the receiver to a folding mode, it can be folded and stored when not in use to reduce storage space, and it can be unfolded when in use for the convenience of the operator.

[0024] A slot is provided on the snap plate 9, and the block 10 corresponds to the slot position. The width of the block 10 is consistent with the width of the slot, and the length of the block 10 is 1 cm longer than the length of the slot, which facilitates the snap plate 9 to engage the block 10, thereby playing a fixing role.
