DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1 to 4 The deep well sampling device for water resource survey in the embodiment comprises a folding and unfolding assembly and a sampling assembly.

[0022] The sampling assembly comprises a sampling cylinder 7, the top of the sampling cylinder 7 is fixedly connected with a cover 9, the cover 9 is slidably connected with a connecting rod 6 in the inside, the bottom of the connecting rod 6 is fixedly connected with a sealing plug 17, the sealing plug 17 is matched with a water inlet 13 arranged in the bottom of the sampling cylinder 7, the top of the connecting rod 6 is fixedly connected with a connecting rope 16, one end of the connecting rope 16 is fixedly connected with the caliper wire 4, the outside of the connecting rod 6 is fixedly connected with a disc 8 arranged on the top of the sampling cylinder 7, the disc 8 and the inner wall of the cover 9 are provided with an extension spring 10, the cover 9 is in the shape of a circular truncated cone, and the extension spring 10 is a conical spring.

[0023] It can be understood that the sealing plug 17 is in the state of being clamped in the inside of the water inlet 13 when the cover 9 does not receive pressure, so that the sampling cylinder 7 is in a sealed state.

[0024] In the embodiment, the outside of the connecting rope 16 is sleeved with a weight 11 and a magnet 12, the magnet 12 is located above the weight 11, the outside of the connecting rope 16 is fixedly connected with a limiting ball 14, the diameter of the limiting ball 14 is smaller than the hole diameter of the weight 11, and the limiting ball 14 is larger than the hole diameter of the magnet 12.

[0025] The limiting ball 14 is used for limiting the falling position of the magnet 12, and the weight 11 is made of a magnetic material, so when the magnet 12 falls above the weight 11, the magnet 12 will attract the weight 11 to move upwards and loosen the pressure on the cover 9.

[0026] The limiting ball 14 has a water pressure sensor 15 embedded inside it, and a buffer sleeve is provided on the outside of the limiting ball 14.

[0027] The buffer sleeve is made of rubber and serves to cushion and protect the limiting ball 14, reducing the impact of the falling magnet 12.

[0028] Please see Figure 1 , Figure 2 The rotating cylinder 1 includes a fixed plate 101, a cylinder body 102, and a movable plate 103. The fixed plate 101 is mounted on the support frame 2. The cylinder body 102 is rotatably connected to the side wall of the fixed plate 101. The movable plate 103 is fixed on the side of the cylinder body 102 away from the fixed plate 101. A rotating plate 3 is fixedly connected to the side wall of the movable plate 103. A handle 5 is fixedly connected to the rotating plate 3. An operation panel and an alarm are provided on the side wall of the support frame 2.

[0029] It should be noted that the water pressure sensor 15 is electrically connected to the alarm and the control panel. The control panel can be used to set the water pressure sensor 15 to a specified depth to transmit a signal to the alarm and trigger an alarm, thereby reminding the user to lower the weight 11.

[0030] The working principle of the above embodiment is as follows: In use, first place the retraction assembly near the wellhead. Set the water pressure sensor 15 to transmit a signal to the alarm when it reaches a specified depth via the operation panel. Hold the weight 11 and magnet 12 in your hand, and rotate the lever 5 to lower the closed sampling tube 7 into the deep well using the caliper rope 4. When it reaches the specified depth, the water pressure sensor 15 will trigger an alarm, allowing the weight 11 to be lowered. It will then slide down the connecting rope 16 to the top of the casing 9. Under the influence of gravity, the casing 9 and the sampling tube 7 will move downwards, thereby opening the inlet 13 and allowing water to enter the sampling tube 7. Then, the magnet 12 is lowered and falls onto the top of the limiting ball 14, which will attract the weight 11 from the top of the casing 9. Under the rebound force of the extension spring 10, the sampling tube 7 can return to its original position and seal the inlet 13. Then, by reversing the grip 3, the sampling tube 7 can be retrieved from the well to complete the sampling, thus facilitating the accurate collection of groundwater at a specified depth.
