DETAILED DESCRIPTION

[0026] The technical solutions and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0027] Please refer to Figures 1 to 2 The present invention provides a groundwater sampling device 10, comprising a sampling assembly 20, a buoyancy assembly 30, a trigger assembly 40 and an alarm assembly 50. The buoyancy assembly 30 and the trigger assembly 40 are both installed inside the sampling assembly 20, the alarm assembly 50 is arranged at the top of the sampling assembly 20, the trigger assembly 40 is located between the alarm assembly 50 and the buoyancy assembly 30, and the trigger assembly 40 and the alarm assembly 50 are electrically connected; the sampling assembly 20 is used to collect groundwater samples, the buoyancy assembly 30 is used to rise as the groundwater level inside the sampling assembly 20 rises, and when the groundwater level reaches a preset height, it contacts the trigger assembly 40 to generate a trigger signal, so that the alarm assembly 50 issues an alarm prompt. In this way, groundwater samples are collected through the sampling assembly 20, and as the groundwater level inside the sampling assembly 20 rises, the buoyancy assembly 30 rises accordingly. When the groundwater level reaches a preset height, the buoyancy assembly 30 contacts the trigger assembly 40 to generate a trigger signal. After receiving the trigger signal, the alarm assembly 50 issues a high alarm prompt, thereby notifying the staff on the ground, thereby improving the efficiency of groundwater sampling.

[0028] Please refer to Figures 3 and 4Furthermore, the sampling assembly 20 includes a sampling cylinder 21, a check ball 22 and a sampling cover 23. The bottom end of the sampling cylinder 21 is provided with a water inlet 24 for collecting groundwater samples; the sampling cover 23 is installed at the top of the sampling cylinder 21, and the check ball 22 is installed in the sampling cylinder 21 to prevent the groundwater sample in the sampling cylinder 21 from leaking out from the water inlet 24. Specifically, the density of the check ball 22 is greater than the density of groundwater. After the sampling cylinder 21 enters the water body, due to the pressure difference between the inside of the sampling cylinder 21 and the water body, the groundwater enters the sampling cylinder 21 from the water inlet 24 and uses the pressure difference to lift the check ball 22. When the sampling cylinder 21 is filled with groundwater, the pressure difference between the inside of the sampling cylinder 21 and the water body disappears, and the check ball 22 falls to the water inlet 24 under the action of gravity, thereby sealing the water inlet 24 and preventing the groundwater sample in the sampling cylinder 21 from flowing out.

[0029] Furthermore, a pull ring 25 is provided on the top of the sampling cover 23 to facilitate the staff to carry the groundwater sampling device 10, and is used to connect with a rope to facilitate placing the groundwater sampling device 10 into the sampling well.

[0030] Please refer to Figure 2 and Figure 5 Furthermore, the buoyancy component 30 includes a limit member 31 and a buoyancy component 32. The limit member 31 is fixedly installed in the sampling tube 21. A limit cylinder 33 is provided on the limit member 31. The top end of the buoyancy component 32 is slidably installed in the limit cylinder 33 so that when the buoyancy component 32 rises, its top end can move along the length direction of the limit cylinder 33. In this way, by coaxially arranging the limit cylinder 33 and the trigger end of the trigger component 40, the top end of the buoyancy component 32 can contact the trigger end of the trigger component 40 after rising, thereby generating a trigger signal, so that the alarm component 50 issues an alarm prompt.

[0031] Please refer to Figure 2 and Figure 6 Furthermore, the trigger assembly 40 includes a first contact 41, an elastic membrane 42 and a second contact 43. The first contact 41 is arranged below the alarm assembly 50, the elastic membrane 42 is arranged below the first contact 41, and the second contact 43 is arranged on the elastic membrane 42. The first contact 41, the second contact 43 and the limiting cylinder 33 are coaxially arranged so that the second contact 43 contacts the first contact 41 through the rising of the buoyancy member 32. When the top end of the buoyancy member 32 lifts the elastic membrane 42, the second contact 43 contacts the first contact 41. The first contact 41 and the second contact 43 are electrically connected to the two ends of the alarm assembly 50 respectively, so that when the second contact 43 contacts the first contact 41, the alarm assembly 50 is triggered.

[0032] Furthermore, sealing rubber rings are provided on both sides of the elastic membrane 42 to prevent the groundwater sample from flowing from the sampling tube 21 into the alarm component 50 .

[0033] Example 1: Using the groundwater sampling device 10 to collect groundwater close to the ground

[0034] Please refer to Figure 7 In this embodiment, the alarm component 50 includes a first battery 51 and a buzzer 52. One end of the first battery 51 is electrically connected to the buzzer 52 and the first contact 41 in sequence, and the other end is electrically connected to the second contact 43. In this way, when the groundwater level in the sampling tube 21 reaches a specified height, the top of the buoyancy member 32 lifts the elastic membrane 42, causing the second contact 43 to contact the first contact 41, thereby connecting the circuit between the first battery 51 and the buzzer 52, so that the buzzer 52 emits a sound to alert the staff on the ground.

[0035] Example 2: Using the groundwater sampling device 10 to collect groundwater far from the ground

[0036] Please refer to Figures 7 and 8 In this embodiment, the alarm assembly 50 includes a first battery 51, a signal generator 53, a wearable ring 54, a second battery 55, a signal receiver 56 and an alarm 57. One end of the first battery 51 is electrically connected to the signal generator 53 and the first contact 41 in sequence, and the other end is electrically connected to the second contact 43; the second battery 55, the signal receiver 56 and the alarm 57 are all installed on the wearable ring 54, the second battery 55 is electrically connected to the signal receiver 56 and the alarm 57 respectively, and the signal receiver 56 is electrically connected to the alarm 57 to provide the signal receiver 53 with an alarm. 6 and the alarm 57 are powered, and the signal receiver 56 is connected to the signal generator 53 for communication; in this way, the operator wears the wearing ring 54 on his wrist. When the groundwater level in the sampling cylinder 21 reaches the specified height, the top of the buoyancy member 32 lifts the elastic membrane 42, so that the second contact 43 contacts the first contact 41, thereby connecting the circuit between the first battery 51 and the signal generator 53, so that the signal generator 53 sends a start signal to the signal receiver 56. After receiving the start signal, the signal receiver 56 starts the alarm 57, and the alarm 57 sends an alarm prompt, thereby notifying the operator.

[0037] In this embodiment, the alarm 57 is an electronic device with a vibration or sound-generating function, such as a buzzer 52 .

[0042] 4. Remove the groundwater sampling device 10 from the sampling well;
