The connecting tube and the measuring tube have a good protective effect on the float liquid level sensor, reducing the probability of collision damage during the process of the float liquid level sensor descending into the observation well.

[0007] Furthermore, the connecting tube is provided with an elastic connecting component for abutting against the inner wall of the observation well, the elastic connecting component is provided with a plurality of groups and is evenly distributed about the axis of the connecting tube, the elastic connecting component comprises a first connecting rod hinged to the outer wall of the connecting tube, a second connecting rod hinged to an end of the first connecting rod away from the connecting tube, a circular ring body fixed to an end of the second connecting rod away from the first connecting rod, and a ball movably connected to the inner side of the circular ring body, the connecting tube is provided with a supporting component for abutting against the second connecting rod and making the ball close to the inner wall of the observation well.

Due to the characteristics of the ball, interference with the descent of the measuring rope is avoided, ensuring that the measuring rope can descend smoothly during the measurement process, and reducing the probability of the measuring tube shaking under the action of gravity and colliding with the inner wall of the observation well, which plays a good protective role for the exploration equipment and is conducive to the smooth progress of the subsequent exploration work.

[0013] Furthermore, a first transverse plate is fixed between the two mounting seats, and a first circular ring for the measuring rope to pass through is arranged in the middle of the first transverse plate.

[0014] By adopting the above technical solution, the first horizontal plate cooperates with the first circular ring, so that the measuring rope can maintain smooth lifting and lowering in the vertical direction after being relaxed on the winding roller.

The top of the measuring tube is penetrated by an arc-shaped through groove for the main pipeline and the nozzle to pass through. The nozzles are provided with multiple nozzles and are distributed in a straight line in the vertical direction. A driving component for driving the measuring tube to rotate is provided on the connecting tube, and the top of the measuring tube is provided with an arc-shaped through groove for the main pipeline to slide with.

[0016] By adopting the above technical solution, after the water pump starts working, the water in the water tank is pumped into the main pipeline through the soft water pipe and then sprayed out by the nozzle, so as to flush the arc filter screen, so that the arc filter screen is kept clean, the filtering effect is guaranteed, and the probability of debris entering the measuring cylinder and contaminating the float liquid level sensor is reduced.

[0018] By adopting the above technical solution, the motor drives the driving gear to rotate after it starts working. Since the driving gear is engaged with the teeth on the top of the measuring cylinder, the measuring cylinder is rotatably connected with the connecting cylinder, thereby causing the measuring cylinder to rotate, and the main pipeline rotates along the arc-shaped groove. After the water pump starts working, the water in the water tank is pumped to the main pipeline and sprayed out by the nozzle, thereby flushing the entire arc-shaped filter screen.

[0019] Furthermore, a lifting assembly for driving the main pipeline to rise and fall is provided on the connecting tube, and the lifting assembly includes a cylinder fixed to the side wall of the connecting tube near the upper end of the connecting tube and a connecting plate fixed to the lower end of the piston rod of the cylinder, and one side of the connecting plate is fixed to a position of the main pipeline near its upper end.

[0023] S1. Assemble equipment;

[0024] S2. Turn the winding roller and gradually release the measuring rope, so that the installation tube, the connecting tube and the measuring tube all drop synchronously with the connecting rope.

The arc filter blocks the debris, ensuring the cleanliness of the float liquid level sensor, so that the float liquid level sensor can measure the liquid level in the observation well.

[0025] S3. When the measuring rope drives the float liquid level sensor to descend, the horizontal spring contacts the second connecting rod, so that the ball and the inner wall of the observation well are kept in a tight state. At the same time, due to the characteristics of the ball, interference with the descent of the measuring rope is avoided, ensuring that the measuring rope can descend smoothly during the measurement process, reducing the probability of the measuring tube shaking under the action of gravity and colliding with the inner wall of the observation well, and playing a good protective role for the exploration equipment;

[0026] S4. After the measurement is completed, when the arc filter is full of debris, the staff can start the cylinder and the motor. The piston rod of the cylinder drives the main pipe to descend into the measuring cylinder. The motor drives the driving gear to rotate. Since the driving gear is engaged with the teeth on the top of the measuring cylinder, the measuring cylinder and the connecting cylinder are connected in rotation, so that the measuring cylinder rotates, and the main pipe rotates along the arc groove. After the water pump works, the water in the water tank is pumped into the main pipe and sprayed out by the nozzle, so as to flush the arc filter, ensuring that the water in the observation well can smoothly enter the measuring cylinder from the arc filter in the later stage, so that the float liquid level sensor can measure the liquid level in the observation well.

[0027] By adopting the above technical solution,

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. In this application, the arc filter screen filters the debris in the observation well, keeping the surface of the float liquid level sensor clean.

[0044] With the arrangement of the support assembly 5, the ball 44 in the annular body 43 on the second connecting rod 42 is in close contact with the inner wall of the observation well 1.

A plurality of nozzles 75 are provided and distributed in a straight line in the vertical direction. A driving component 8 for driving the measuring tube 33 to rotate is provided on the connecting tube 32. After the water pump 72 starts working, the water in the water tank 71 is pumped into the main pipe 74 through the soft water pipe 73, and then sprayed out by the nozzle 75, so as to flush the arc filter screen 3311, so that the arc filter screen 3311 remains clean, ensuring the filtering effect and reducing the probability of debris entering the measuring tube 33 and contaminating the float liquid level sensor 24.

After the motor 82 is working, the driving gear 83 is driven to rotate. Since the driving gear 83 is meshed with the latching teeth 84 at the top of the measuring tube 33, the measuring tube 33 is connected to the connecting tube 32 in rotation, so that the measuring tube 33 is slowly rotated, the main pipeline 74 is rotated along the arc groove 333, and the water pump 72 is operated to pump water in the water tank 71 to the main pipeline 74, and the water is sprayed out by the nozzle 75, so as to wash the entire arc filter 3311.

[0051] The piston rod of the cylinder 91 drives the main pipe 74 to descend into the measuring tube 33. During this process, the soft water pipe 73 moves synchronously with the main pipe 74. The soft water pipe 73 cooperates with the movable groove 1131 on the guide rod 113, so that the guide rod 113 drives the sliding block 111 to move synchronously and the arc spring 112 is compressed, so that the soft water pipe 73 remains open, reducing the probability of excessive bending of the soft water pipe 73 during the lifting process and affecting the water flow effect.

[0056] S3. When the measuring rope 23 drives the float liquid level sensor 24 to descend, the horizontal spring 51 abuts against the second connecting rod 42, so that the ball 44 is kept in a tight state with the inner wall of the observation well 1. At the same time, due to the characteristics of the ball 44, interference with the descent of the measuring rope 23 is avoided, ensuring that the measuring rope 23 can descend smoothly during the measurement process, reducing the probability of the measuring tube 33 shaking under the action of gravity and colliding with the inner wall of the observation well 1, and playing a good protective role for the exploration equipment;

[0057] S4. After the measurement is completed, when the arc filter 3311 is covered with debris, the staff can start the cylinder 91 and the motor 82. The piston rod of the cylinder 91 drives the main pipe 74 to descend into the measuring cylinder 33. The motor 82 drives the driving gear 83 to rotate. Since the driving gear 83 is engaged with the latching tooth 84 at the top of the measuring cylinder 33, the measuring cylinder 33 is rotatably connected with the connecting cylinder 32, so that the measuring cylinder 33 rotates, and the main pipe 74 rotates along the arc groove 333. After the water pump 72 works, the water in the water tank 71 is pumped into the main pipe 74 and sprayed out by the nozzle 75, so as to flush the arc filter 3311, ensuring that the water in the observation well 1 can smoothly enter the measuring cylinder 33 from the arc filter 3311 in the later stage, so that the float liquid level sensor 24 can measure the liquid level in the observation well 1.
