[0028] The embodiment of the present application discloses a fill thickness detection device for water conservancy supervision.

[0029] Reference Figure 1 , 2 A fill thickness detection device for water conservancy supervision includes a rectangular base 1, four support rods 2 are arranged at the four corners of the top of the base 1, and a rectangular top seat 3 is fixedly arranged on the top of the four support pipes, so that the base 1 and the top seat 3 are parallel to each other through the four support rods; Four sets of moving wheels 4 are arranged at the bottom of the base 1, and the four sets of moving wheels 4 are arranged at the four corners of the bottom of the base 1 respectively. A handle frame 5 is arranged on one side of the periphery of the base 1 along its length direction. The staff can move the base 1 under the action of the moving wheels 4 by driving the handle frame 5; A hanging rope 6 is provided at the bottom of the top seat 3, and a plumb bob 61 is bolted at the bottom of the hanging rope 6. The plumb bob 61 can swing with the height of the terrain through the hanging rope 6 until the top seat 3 is kept in a horizontal state. The plumb bob 61 will remain in a horizontal state and motionless. The staff can judge whether the detection device is placed horizontally according to the swing of the plumb bob 61 and the hanging rope 6, and thus adjust the fixing mechanism 8 to make the plumb bob 61 finally maintain a stable state; A measuring mechanism 7 is provided between the base 1 and the top seat 3. The measuring mechanism 7 is located at the center of the base 1 and the top seat 3. The measuring mechanism 7 can penetrate the top seat 3 and the base 1 from top to bottom until it contacts and is inserted into the ground, thereby detecting the thickness of the fill layer.

[0030] In the present application, when the detection device moves to a suitable position via the moving wheel 4, it stops, and after the plumb bob 61 on the hanging rope 6 maintains a horizontal state, the staff starts the measuring mechanism 7 to detect the fill layer.

[0031] Reference Figure 2 , 3Specifically, in this embodiment, four sets of fixing mechanisms 8 are arranged on the base 1, and the four sets of fixing mechanisms 8 are respectively fixedly arranged at the four corners of the top of the base 1, and each fixing mechanism 8 is respectively arranged corresponding to a support rod 2, and the fixing mechanism 8 can pass through the base 1 from top to bottom to contact the ground and be inserted into the ground; The fixing mechanism 8 includes an H-shaped lifting support seat 81, which is vertically arranged on the top of the base 1. A lifting drive member 82 is arranged on the side of the lifting support seat 81 away from the support rod 2, and the movable end of the lifting drive member 82 is located on the top of the lifting drive member 82. A lifting screw rod 83 and two sets of lifting slide rails 84 are arranged along the length direction of the lifting support seat 81 close to the support rod 2. The two sets of lifting slide rails 84 are arranged in parallel and at intervals on both sides of the lifting screw rod 83, and the two sets of lifting slide rails 84 and the lifting screw rod 83 are arranged parallel to each other. The base 1 is located at the bottom position of the lifting support seat 81 close to the support rod 2. A through fixing hole is opened from top to bottom. The bottoms of the two sets of lifting slide rails 84 and the lifting screw rod 83 extend downward to the inside of the base 1 through the fixing hole. In order to realize the rotation of the lifting screw 83, a driving gear 85 is rotatably provided at the top movable end of the lifting drive member 82, and a driven gear 86 is provided at the top of the lifting screw 83. The driving gear 85 and the driven gear 86 are connected by a chain transmission. The lifting drive member 82 drives the driving gear 85 and the driven gear 86 to rotate, so as to realize the rotation control of the lifting screw 83. The transmission accuracy and efficiency of the driving gear 85 and the driven gear 86 connected by the chain are high. A cylindrical fixing column 87 is arranged between the lifting support seat 81 and the support rod 2. The fixing column 87 can pass through the base 1 from top to bottom through the fixing hole and contact the ground. A mounting seat 88 is arranged on the side of the fixing column 87 close to the lifting support seat 81. The mounting seat 88 is provided with a lifting block 881 and a lifting slider 882 on the side of the lifting support seat 81. There are two groups of lifting sliders 882, which are respectively arranged on both sides of the mounting seat 88. A lifting hole which is through and has threads on the inner circumference is opened on the lifting block 881. The lifting block 881 is connected with the lifting screw rod 83 through the lifting hole. The lifting slider 882 can be slidably arranged on the lifting rail 84. A limiting block is arranged at the bottom of the lifting screw rod 83 for limiting the lifting block 881 lifted and lowered on the lifting screw rod 83. Finally, the fixing column 87 passes through the fixing hole through the fixing seat and the lifting screw rod 83 under the action of the lifting drive member 82 to contact the ground and perform a fixing action.

[0032] In addition, in order to achieve a better fixing effect between the fixing column 87 and the ground, five nail grips 89 are arranged at the bottom of the fixing column 87. The five nail grips 89 are arranged in a surrounding manner with the center of the cylindrical bottom as the axis, and a horizontal support plate 891 is arranged in the middle of the outer side of each nail grip 89. On the one hand, when the fixing column 87 moves toward the direction close to the soil layer, the nail grip 89 abuts against the soil layer. The smaller the force-bearing area, the greater the pressure, which facilitates the insertion of the fixing column 87 into the soil layer. On the other hand, when the nail grip 89 is inserted into the ground, the support plate 891 on the nail grip 89 contacts the top of the ground, providing a more stable support for the nail grip 89 and preventing the nail grip 89 from tilting or moving due to external force.

[0033] During actual use, when the detection device is moved to a suitable position, several fixing mechanisms 8 located at different positions are adjusted according to the height of the terrain, so that each fixing mechanism 8 controls the lifting drive member 82 to adjust the lifting height of the fixing column 87 according to the different degrees of depression of the terrain at the bottom of the fixing column 87, so as to adapt to different terrains, so that the base 1 and the top seat 3 are always fixed in a horizontal state, thereby improving the accuracy of the measurement results of the measuring mechanism 7.

[0034] Reference Figure 1 Specifically, in the present embodiment, the measuring mechanism 7 comprises a measuring rod 71 and an insertion rod 72. An accommodating cavity is provided on the top of the insertion rod 72 from top to bottom. The bottom of the measuring rod 71 is inserted into the top of the insertion rod 72 through the accommodating cavity. A threaded plug 73 is provided at the bottom of the insertion rod 72. Locking holes are provided at the bottom of the measuring rod 71 and the top of the insertion rod 72. Bolts and nuts are passed through the locking holes to lock the measuring rod 71 and the insertion rod 72. A through measuring hole is provided on the top seat 3. The measuring rod 71 passes through the measuring hole to connect with the insertion rod 72. A through detection hole is provided on the base 1. The insertion rod 72 passes through the detection hole to contact the ground. A safety pin 74 is provided on the measuring rod 71. A pin hole for the safety pin 74 to be inserted is provided on the measuring rod 71. The safety pin 74 is located above the top seat 3.

[0035] During actual use, when measuring the fill thickness, the staff unplugs the installation pin on the measuring rod 71, so that the insertion rod 72 drives the measuring rod 71 to be inserted into the ground, and rotates the insertion rod 72 to drive the plug 73 to be inserted into the ground until it is inserted into the appropriate position. The thickness of the fill layer can be known through the measuring rod 71.

[0036] The implementation principle of a fill thickness detection device and a detection method for water conservancy supervision in an embodiment of the present application is as follows: the staff moves the base 1 with the moving wheels 4 to the fill position to be detected through the handle frame 5, and controls the lifting drive parts 82 at different positions according to the terrain height at the bottom of different fixed columns 87, so that the active gear 85 on the lifting drive part 82 rotates, and then drives the driven gear 86 to move through the chain, so that the lifting screw rod 83 rotates, and the fixed column 87 passes through the base 1 from above the base 1 along the lifting screw rod 83 through the lifting block 881 on the mounting seat 88 to contact the ground. During the contact process, the nail grip 89 at the bottom of the fixed column 87 is inserted into the ground, thereby realizing the fixing action. Finally, the staff pulls out the installation pin on the measuring rod 71, so that the insertion rod 72 drives the measuring rod 71 to be inserted into the ground, and rotates the insertion rod 72 to drive the plug 73 to be inserted into the ground until it is inserted into the appropriate position. The thickness of the fill layer can be known through the measuring rod 71.

[0037] The embodiment of the present application also discloses a method for detecting fill thickness for water conservancy supervision.

[0038] S1: Moving the detection device, the staff moves the base 1 with the moving wheels 4 to the filling position to be detected through the handle frame 5; S2: After the moving wheel 4 stops moving, the staff controls the lifting drive member 82 at different positions to rotate the driving gear 85 on the lifting drive member 82, and then drives the driven gear 86 to move through the chain, so that the lifting screw 83 rotates, and the fixed column 87 passes through the base 1 from above the base 1 along the lifting screw 83 through the lifting block 881 on the mounting seat 88 and contacts the ground. During the contact process, the nail grip 89 at the bottom of the fixed column 87 is inserted into the ground, thereby realizing the fixing action; S3: Adjust the placement angle. According to the different terrain heights, the staff controls the fixed columns 87 at the four corners of the base 1 to perform different degrees of lifting and lowering. If the terrain is convex, the lifting drive 82 is used to lift the fixed columns 87. If the terrain is concave, the lifting drive 82 is used to lower the fixed columns 87, so that the base 1 is always kept in a horizontal state, and then the top seat 3 is also kept in a horizontal state. Finally, the swing of the plumb bob 61 at the bottom of the top seat 3 is observed to determine whether it is kept in a horizontal state. S4: To measure the fill thickness, the worker unplugs the installation pin on the measuring rod 71, so that the insertion rod 72 drives the measuring rod 71 to be inserted into the ground, and rotates the insertion rod 72 to drive the plug 73 to be inserted into the ground until it is inserted into the appropriate position. The thickness of the fill layer can be known through the measuring rod 71.
