[0040] During the process of inserting the device, the soil pushes up the sealing plate 803, keeping the sealing plate 803 always closed to the device and preventing soil from entering the device. Thus, it can prevent the soil from entering the device and affecting the detection of the device. When the device is inserted to a certain depth, only need to pull the device up a little. At this time, due to the elasticity of the second spring 802, the sealing plate 803 will be pulled into the receiving box 801, so that the sealing plate 803 is opened, facilitating water to enter the device for detection. At the same time, the magnetic sliding block 804 and the sealing cloth 805 can ensure that the receiving box 801 is always in a closed state to prevent soil from entering.

[0041] As Figure 4 and Figure 7 shown, a connecting sleeve rod 9 is provided at the upper end of the detection outer sleeve 501, and a rack 10 is provided on one side of the connecting sleeve rod 9.

The upper end of the connecting lower rod 1101 is connected to the connecting upper rod 1102, and a connecting positioning sleeve 1103 is provided outside the connecting upper rod 1102;

[0044] While extending, the connecting lower rod 1101 and the connecting upper rod 1102 will also be docked to facilitate the gas flow. The connecting positioning sleeve 1103 can facilitate the precise docking and sealing of the connecting lower rod 1101 and the connecting upper rod 1102.

[0045] As Figure 7 shown, the first locking component 12 includes an inner connecting ring 1201, a clamping ball 1202, an outer connecting ring 1203, a retaining ring 1204, and a guide rod 1205. The outer part of the inner connecting ring 1201 is provided with the clamping ball 1202. The outer part of the clamping ball 1202 is provided with the outer connecting ring 1203. The outer part of the outer connecting ring 1203 is provided with the retaining ring 1204. The upper end of the retaining ring 1204 is provided with the guide rod 1205;

[0046] Insert the connecting sleeve rod 9 above the detection outer sleeve 501 and snap the clamping ball 1202 into the inner connecting ring 1201, so as to realize the connection between the inner connecting ring 1201 and the outer connecting ring 1203, and further connect the detection outer sleeve 501 and the connecting sleeve rod 9 together, extend the device, make the device have an infinite extension function, and facilitate the device to detect the water seepage conditions at different depths.

[0047] As Figure 4 shown, the detection component 15 includes a protective shell 1501, a barometric pressure sensor 1502 and a barometric pressure box 1503, and the barometric pressure sensor 1502 is installed inside the protective shell 1501, and the barometric pressure box 1503 is arranged at the lower end of the barometric pressure sensor 1502;

[0048] Convey the compressed gas into the barometric pressure box 1503 through the ventilation pipe 502, the connecting upper rod 1102 and the connecting lower rod 1101, so that the data of the barometric pressure sensor 1502 changes, and an alarm is given in time.

[0049] Working principle: First, push the device to the specified position through the wheels under the outer shell 101, and then detect the levelness of the device through the level sensor above the inner shell 107. If the levelness of the device deviates, the eight cylinders 104 around the inner shell 107 will be controlled to retract and retract, and the levelness of the inner shell 107 can be detected by relying on the movable connection between the connecting round head 105 and the connecting round sleeve 106, so that the inner shell 107 can be kept horizontal, and the detection jacket 501 can be inserted in a vertical downward state, and then the connecting sleeve rod 9 is inserted above the detection jacket 501, and the ball 1202 is inserted into the inner connecting ring 1201, so as to realize the connection between the inner connecting ring 1201 and the outer connecting ring 1203, thereby making the detection jacket 501 501 is connected with the connecting sleeve rod 9 to extend the equipment. During the extension, the connecting lower rod 1101 and the connecting upper rod 1102 will also be docked to facilitate the flow of gas. The connecting positioning sleeve 1103 can facilitate the accurate docking and sealing of the connecting lower rod 1101 and the connecting upper rod 1102. Multiple connecting sleeve rods 9 can be spliced ​​according to the required length. When the connecting sleeve rods 9 are spliced, the detection component 15 is connected to the connecting sleeve rod 9 through the second locking component 13 and the second connecting component 14, and then the motor 108 is turned on to drive the gear 2 to rotate. The connecting sleeve rod 9 is moved downward by the engagement of the gear 2 and the rack 10, so that the lower pressure head 6 is inserted to the specified depth. During the insertion process, the push plate 704 is used to extend the positioning rod 703 and the first spring 70 The elastic telescopic structure formed between 2 and the fixed plate 701 can position the detection jacket 501, so that the detection jacket 501 can only move up and down, preventing the detection jacket 501 from shaking and affecting the insertion effect of the detection jacket 501. At the same time, when the detection jacket 501 moves downward, it will also drive the fitting sleeve 302 wrapped on the central axis 301 to be released, so that the fitting sleeve 302 is pushed to the detection jacket 501 by rotating the shaft 304 and fits with the rack 10, preventing the soil from being embedded in the rack 10 after the equipment enters the soil, affecting the gear 2 to remove the equipment from the soil. The coil spring 4 can drive the central axis 301 to rotate when the equipment is recovered, and reel up the fitting sleeve 302. When the equipment is inserted downward, the sealing plate 803 is pushed up after the soil is pushed back. The device is directly closed to prevent mud from entering the device. When the device is inserted to a certain depth, it only needs to be pulled back a little upward. At this time, the elasticity of the second spring 802 will pull the sealing plate 803 into the storage box 801, so that the sealing plate 803 is opened. At the same time, the magnetic sliding block 804 and the sealing cloth 805 can ensure that the storage box 801 is always in a closed state to prevent mud from entering. When the sealing plate 803 is opened, if there is water seepage, water will enter the detection jacket 501, thereby exerting a certain pressure on the inflatable bag 504, and then the compressed gas is transported to the air pressure box 1503 through the ventilation pipe 502, the upper rod 1102 and the lower rod 1101, so that the data of the air pressure sensor 1502 changes, thereby timely alarming.
