[0014] A warning method of a multifunctional excavation warning device comprises the following steps:

[0015] Step 1: After the inspection and maintenance of the detector body is completed, first manually pull the L-shaped rod away from the bucket. The L-shaped rod moves away from the bucket to break away from the contact with the protection hole and release the limit on the mounting rod. After the limit of the mounting rod is released, manually pull the mounting rod downward;

[0016] Step 2: The mounting rod moves downward to squeeze the No. 2 spring. The No. 2 spring is deformed and stores force due to the squeezing of the mounting rod. At the same time, the detector body is placed inside the sealing frame. The detector body entering the sealing frame contacts the placement plate and squeezes the placement plate. The placement plate is squeezed by the detector body and moves toward the direction close to the bucket.

[0017] Step 3: The placement plate moves toward the direction close to the bucket to squeeze the No. 1 spring. The No. 1 spring is squeezed by the placement plate to deform and accumulate force. At the same time, the detector body entering the sealing frame continues to move so that the mounting rod contacts the mounting groove. When the mounting rod contacts the mounting groove, the mounting rod moves upward and resets under the elastic force of the No. 2 spring. The mounting rod moves upward and resets to contact the inner wall of the mounting groove and restores the limit of the detector body to complete the installation of the detector body.

[0018] Step 4: After the detector body is installed stably, manually pull the sealing door longitudinally to restore the seal of the sealing frame. After the seal of the sealing frame is restored, start the detector body to detect the pipes crossing under the waterway. When the detector body detects metal pipes, it will automatically alarm to remind the operator to stop dredging operations.

[0019] The present invention provides a multifunctional excavation early warning device. It has the following beneficial effects:

[0020] (1) In the present invention, a metal detection module is built into the detector body. When a metal pipe is detected, an alarm is automatically sounded to remind the operator to stop dredging operations. When the detector body needs to be inspected and maintained, the L-shaped rod needs to be manually pulled away from the bucket. The L-shaped rod moves away from the bucket to break away from the contact with the protection hole and releases the limit on the installation rod. The L-shaped rod can effectively prevent the detector body from being accidentally dismantled due to being hit by foreign objects during the excavation process, thereby reducing the risk of damage to the detector body and accidental dismantling, and improving the detection accuracy and reliability. The installation of the detector body is completed by moving the installation rod upward to reset the contact with the inner wall of the installation groove and restore the limit on the detector body. The convenient installation process reduces the time required for maintenance and replacement.

[0021] (2) In the present invention, after the baffle plate is separated from the contact with the linkage block, the baffle plate moves toward the detector body under the elastic force of the No. 4 spring to seal the top of the sealing groove. The sealing door moves to drive the L-shaped plate to move to block and seal the top of the protective groove, thereby further enhancing the sealing performance of the sealing frame. The enhanced sealing performance can effectively prevent mud from entering the sealing frame and damaging the detector body, thereby reducing the risk of damage to the detector body. The enhanced sealing performance helps to maintain the stability of the components inside the detector body, improve detection accuracy and reliability, and ensure that the detector can work normally under different conditions.

[0022] (3) In the present invention, the displacement rod moves in the direction away from the L-shaped plate under the elastic action of the No. 5 spring. The displacement rod moves in the direction away from the L-shaped plate, thereby driving the inclined plate to move. The inclined plate moves to contact and squeeze the clamping rod. The clamping rod is squeezed by the inclined plate and moves downward to assist in clamping and fixing the side of the detector body. The squeezing of the clamping rod provides additional side support, thereby reducing the displacement or shaking of the detector during operation and improving the stability of the overall equipment. In addition, the auxiliary clamping can ensure that the detector body is more tightly fixed in the predetermined position, thereby improving the accuracy of detection.

[0033] A No. 1 spring is arranged between the placement rod 5 and the placement plate 6, and the No. 1 spring can drive the placement plate 6 to reset. The installation rod 10 contacts the inner wall of the installation groove 8, and the detector body 7 contacts the inner wall of the sealing frame 3. The L-shaped rod 13 can effectively prevent the detector body 7 from being accidentally disassembled due to being hit by foreign objects during the excavation process, thereby reducing the risk of damage and accidental disassembly of the detector body 7.

[0034] A No. 2 spring is arranged between the mounting frame 9 and the mounting rod 10, and the No. 2 spring can drive the mounting rod 10 to reset. A No. 3 spring is arranged between the stabilizing rod 12 and the L-shaped rod 13, and the No. 3 spring can drive the L-shaped rod 13 to reset. The L-shaped rod 13 contacts the inner wall of the protective hole 11.

[0035] A warning method of a multifunctional excavation warning device comprises the following steps:

[0036] Step 1: After the inspection and maintenance of the detector body 7 is completed, first manually pull the L-shaped rod 13 to move away from the bucket 1, the L-shaped rod 13 moves away from the bucket 1 to break away from the contact with the protection hole 11 and release the limit on the mounting rod 10, and after the limit of the mounting rod 10 is released, manually pull the mounting rod 10 to move downward;

[0037] Step 2: The mounting rod 10 moves downward to squeeze the No. 2 spring. The No. 2 spring is deformed and stores force due to the squeezing of the mounting rod 10. At the same time, the detector body 7 is placed into the sealing frame 3. The detector body 7 entering the sealing frame 3 contacts the placement plate 6 and squeezes the placement plate 6. The placement plate 6 is squeezed by the detector body 7 and moves toward the direction close to the bucket 1.

[0038] Step 3: The placement plate 6 moves toward the direction close to the bucket 1 to squeeze the No. 1 spring. The No. 1 spring is squeezed by the placement plate 6 to deform and accumulate force. At the same time, the detector body 7 entering the sealing frame 3 continues to move so that the mounting rod 10 contacts the mounting groove 8. When the mounting rod 10 contacts the mounting groove 8, the mounting rod 10 moves upward and resets under the elastic force of the No. 2 spring. The mounting rod 10 moves upward and resets to contact the inner wall of the mounting groove 8 and restores the limit of the detector body 7 to complete the installation of the detector body 7.

[0039] Step 4: After the detector body 7 is installed stably, manually pull the sealing door 4 to move longitudinally to restore the seal of the sealing frame 3. After the seal of the sealing frame 3 is restored, start the detector body 7 to detect the pipeline crossing under the waterway. When the detector body 7 detects a metal pipeline, it will automatically alarm to remind the operator to stop dredging operations.

[0040] When the present embodiment is working: when the detector body 7 needs to be inspected and maintained, the sealing door 4 is first manually pulled to move longitudinally to release the seal on the sealing frame 3. After the seal on the sealing frame 3 is released, the L-shaped rod 13 is manually pulled to move in a direction away from the bucket 1. The L-shaped rod 13 moves in a direction away from the bucket 1 to pull the No. 3 spring. The No. 3 spring is deformed and accumulates force due to the pulling of the L-shaped rod 13. At the same time, the L-shaped rod 13 moves in a direction away from the bucket 1 to break away from the contact with the protection hole 11 and release the limit on the mounting rod 10. After the limit of the mounting rod 10 is released, the mounting rod 10 is manually pulled downward to move. 10 moves downward to break away from the contact with the mounting groove 8 and releases the limit on the detector body 7. After the limit of the detector body 7 is released, the placement plate 6 moves in the direction away from the bucket 1 under the elastic force of the No. 1 spring to pop out the detector body 7 to complete the quick disassembly of the detector body 7. After the inspection and maintenance of the detector body 7 is completed, the L-shaped rod 13 is manually pulled away from the bucket 1. The L-shaped rod 13 moves away from the bucket 1 to break away from the contact with the protection hole 11 and releases the limit on the mounting rod 10. After the limit of the mounting rod 10 is released, the mounting rod 10 is manually pulled downward to move. 10 moves downward to squeeze the No. 2 spring, which is squeezed by the installation rod 10 to produce deformation and accumulate force, and at the same time, the detector body 7 is placed into the sealing frame 3, and the detector body 7 entering the sealing frame 3 contacts the placement plate 6 and squeezes the placement plate 6, and the placement plate 6 is squeezed by the detector body 7 and moves in the direction close to the bucket 1, and the placement plate 6 moves in the direction close to the bucket 1 to squeeze the No. 1 spring, which is squeezed by the placement plate 6 to produce deformation and accumulate force, and at the same time, the detector body 7 entering the sealing frame 3 continues to move so that the installation rod 10 contacts the installation groove 8, and the installation is completed. When the rod 10 contacts the installation groove 8, the installation rod 10 moves upward and resets under the elastic force of the second spring. The installation rod 10 moves upward and resets to contact the inner wall of the installation groove 8 and restores the limit of the detector body 7 to complete the installation of the detector body 7. After the detector body 7 is installed stably, the sealing door 4 is manually pulled longitudinally to restore the seal of the sealing frame 3. After the seal of the sealing frame 3 is restored, the detector body 7 is started to detect the pipeline crossing under the waterway. The detector body 7 has a built-in metal detection module. When the detector body 7 detects a metal pipeline, it automatically alarms to remind the operator to stop dredging operations.

[0045] A No. 6 spring is arranged between the clamping rod 157 and the sealing frame 3. One end of the No. 6 spring is arranged on the surface of the clamping rod 157 and the other end is arranged on the top of the inner wall of the sealing frame 3. The No. 6 spring can drive the clamping rod 157 to reset, and the clamping rod 157 is in contact with the detector body 7. The elastic coefficient of the No. 5 spring is greater than that of the No. 6 spring.

[0046] When this embodiment is working: the placement plate 6 moves in the direction away from the bucket 1 under the elastic force of the No. 1 spring, driving the linkage block 141 to move; the linkage block 141 moves in the direction away from the bucket 1 and contacts the shielding plate 144 and squeezes the inclined surface of the shielding plate 144; the shielding plate 144 is squeezed by the linkage block 141 and moves in the direction away from the detector body 7 to pull the No. 4 spring; the No. 4 spring is pulled by the shielding plate 144 to deform and accumulate force; at the same time, the shielding plate 144 is squeezed by the linkage block 141 and moves in the direction away from the detector body 7 to break away from the contact with the sealing groove 143 and the detector body 7, thereby facilitating the rapid disassembly of the detector body 7. When the placement plate 6 is squeezed by the detector body 7 and moves toward the direction close to the bucket 1, the placement plate 6 moves toward the direction close to the bucket 1 and drives the linkage block 141 to move. The linkage block 141 moves toward the direction close to the bucket 1 and breaks away from the contact with the shielding plate 144. After the shielding plate 144 breaks away from the contact with the linkage block 141, the shielding plate 144 moves toward the direction close to the detector body 7 under the elastic force of the No. 4 spring to seal the top of the sealing groove 143. At the same time, when the sealing door 4 is manually pulled longitudinally to restore the seal on the sealing frame 3, the sealing door 4 moves and drives the L-shaped plate 146 to move to block and seal the top of the protective groove 145 to further enhance the sealing of the sealing frame 3.

[0047] The shielding plate 144 is squeezed by the linkage block 141 and moves in the direction away from the detector body 7, driving the transmission frame 147 to move. The transmission frame 147 moves to contact the displacement rod 154 and squeezes the displacement rod 154.

The No. 5 spring is squeezed by the displacement rod 154 and deforms and accumulates force. At the same time, the displacement rod 154 moves in the direction away from the L-shaped plate 146 and drives the inclined plate 156 to move. The inclined plate 156 moves out of contact with the top of the clamping rod 157. After the clamping rod 157 is out of contact with the inclined plate 156, the clamping rod 157 moves upward under the elastic force of the No. 6 spring to reset and disengage from the contact with the detector body 7. When it moves toward the direction closer to the detector body 7 under the elastic force of the No. 4 spring, the baffle plate 144 moves, driving the transmission frame 147 to move and disengage from the contact with the displacement rod 154. After the displacement rod 154 is released from the transmission frame 147, the displacement rod 154 moves in the direction away from the L-shaped plate 146 under the elastic action of the No. 5 spring. The displacement rod 154 moves in the direction away from the L-shaped plate 146, driving the inclined plate 156 to move. The inclined plate 156 moves and contacts with the clamping rod 157 and squeezes the clamping rod 157. The clamping rod 157 is squeezed by the inclined plate 156 and moves downward to pull the No. 6 spring. The No. 6 spring is deformed and stored by the pulling of the clamping rod 157.

9. A warning method of a multifunctional excavation warning device, using the multifunctional excavation warning device according to claim 8, characterized in that: The following steps are involved: Step 1: After the inspection and maintenance of the detector body (7) is completed, the L-shaped rod (13) is manually pulled to move away from the bucket (1). The L-shaped rod (13) moves away from the bucket (1) to break away from the contact with the protection hole (11) and release the limit on the mounting rod (10). After the limit of the mounting rod (10) is released, the mounting rod (10) is manually pulled downward; Step 2: The mounting rod (10) moves downward to squeeze the No. 2 spring. The No. 2 spring is deformed and stores force due to the squeezing of the mounting rod (10). At the same time, the detector body (7) is placed inside the sealing frame (3). The detector body (7) entering the sealing frame (3) contacts the placement plate (6) and squeezes the placement plate (6). The placement plate (6) is squeezed by the detector body (7) and moves in a direction close to the bucket (1). Step 3: The placement plate (6) moves in a direction close to the bucket (1) to squeeze the No. 1 spring. The No. 1 spring is squeezed by the placement plate (6) to deform and accumulate force. At the same time, the detector body (7) entering the sealing frame (3) continues to move so that the mounting rod (10) contacts the mounting groove (8). When the mounting rod (10) contacts the mounting groove (8), the mounting rod (10) moves upward and resets under the elastic force of the No. 2 spring. The mounting rod (10) moves upward and resets to contact the inner wall of the mounting groove (8) and restores the limit of the detector body (7) to complete the installation of the detector body (7); Step 4: After the detector body (7) is installed stably, manually pull the sealing door (4) to move longitudinally to restore the seal of the sealing frame (3). After the seal of the sealing frame (3) is restored, start the detector body (7) to detect the pipeline crossing under the waterway. When the detector body (7) detects a metal pipeline, it automatically alarms to remind the operator to stop dredging operations.
