The sensor device 200 is installed at the bottom of the sampling device 100, and the sensor device 200 transmits the sensed water body data to the monitoring terminal 310.

[0026] Please refer to Figure 2 The sensing device 200 includes a device housing 210, a water pressure sensor 220, a water temperature sensor 230, a microprocessor 240, and a wireless communication unit 250; the water pressure sensor 220, the water temperature sensor 230, and the wireless communication unit 250 are respectively connected to the microprocessor 240, and the wireless communication unit 250 transmits the collected data to the monitoring terminal 310. Of course, in other embodiments, those skilled in the art may also set other sensors in the device housing 210, so it is not limited thereto.

[0027] Please refer to Figures 3 to 5 The sampling device 100 includes a sampling seat 10, a connecting pipe 20, a blowing device 30 and a filter 40. The sampling seat 10 is provided with a accommodating space 10a for water to enter, and the side wall of the sampling seat 10 is provided with a sampling hole 10b for connecting the accommodating space 10a with the external environment. The filter 40 is installed in the sampling hole 10b. A hollow structure 40a is provided inside the filter 40, and a plurality of blowing holes 40b are provided on the side wall of the filter 40 for connecting the hollow structure 40a with the external environment. The blowing end of the blowing device 30 is connected to the hollow structure 40a through the connecting pipe 20.

[0028] Please continue to refer to Figures 3 to 5 The sampling device 100 further includes a spring device 110 and a sealing cover 120. One end of the sealing cover 120 is rotatably connected to the outer wall 12 of the sampling seat 10. The other end of the sealing cover 120 is installed with a magnetic element 130 and is adsorbed on the outer wall 12 of the sampling seat 10 through the magnetic element 130 and covers the sampling hole 10b. The spring device 110 is installed in the sampling seat 10 and pushes the sealing cover 120 away from the sampling seat 10 when receiving the ejection command. Therefore, in the actual working process, the sealing cover 120 can prevent the water from entering the sampling seat 10 too early during the sinking process of the sampling seat 10, thereby preventing the required water sample from being obtained.

[0029] Please continue to refer to Figures 3 to 5The sampling seat 10 includes an inner wall 11 and an outer wall 12, and a ring-shaped gap 10c is formed between the inner wall 11 and the outer wall 12 for routing and limiting the connecting pipe 20. The accommodating space 10a is located in the inner wall 11, and the gap 10c is connected to the hollow structure 40a. Preferably, the spring device 110 includes an elastic member 111, a push member 112 and a telescopic device 113. The inner wall 11 of the sampling seat 10 is provided with a mounting hole 11a, and the outer wall 12 of the sampling seat 10 is provided with an ejection hole 12a. One end of the elastic member 111 is installed in the mounting hole 11a, and the other end of the elastic member 111 pushes the push member 112 toward the ejection hole 12a. The telescopic device 113 is installed in the gap 10c, and the telescopic device 113 can perform telescopic movement along the height direction of the sampling seat 10 to achieve the obstruction of the movement of the push member 112 or the obstruction of the push member 112 by contact.

[0030] Please continue to refer to Figures 3 to 5 The connecting pipe 20 is connected to the bottom of the hollow structure 40a, and a plurality of blowing holes 40b are arranged along the height direction of the sampling seat 10. Therefore, in the actual working process, when the connecting pipe 20 blows air toward the hollow structure 40a, the gas will escape from bottom to top through the blowing holes 40b, so that the impurities adsorbed on the filter screen 40 can be blown away from bottom to top.

[0031] Please continue to refer to Figures 3 to 5 The filter screen 40 includes an outer frame 41 and a rod assembly 42. The outer frame 41 encloses an installation space 41a. The rod assembly 42 is located in the installation space 41a. The hollow structure 40a includes a first hollow portion 401a and a second hollow portion 402a. The rod assembly 42 is provided with the first hollow portion 401a and a blowing hole 40b. The outer frame 41 is provided with a second hollow portion 402a for connecting the gap 10c and the first hollow portion 401a. Specifically, the rod assembly 42 includes a plurality of rod members 421 arranged in an interlaced manner. Each rod member 421 is provided with a first hollow portion 401a, and each rod member 421 is provided with a blowing hole 40b. For example, the outer side wall 12 of the rod member 421 is recessed inward and formed with a spiral groove 421a. The blowing hole 40b connects the first hollow portion 401a and the groove 421a. By setting the groove 421a, when impurities in the water adhere to the outer wall 12 of the rod body 421, a certain space is still reserved between the blowing hole 40b and the impurities, which can be more conducive to blowing away the impurities through the blowing hole 40b.

[0032] It is worth noting that Figure 5As shown, the filter screen 40 is provided with a polyurethane layer 401, an epoxy resin corrosion-resistant layer 402 and a silicone base layer 403 from the outside to the inside. Through this arrangement, the filter screen 4040 can be made waterproof, corrosion-resistant and have a certain elasticity.

One end of the connecting line 320 is connected to the sampling device 100, and the other end of the connecting line 320 is connected to the cable retracting device 330. The sensor device 200 is installed at the bottom of the sampling device 100, and the sensor device 200 transmits the sensed water body data to the monitoring terminal 310. Therefore, when the present invention is actually working, the sensor device 200 can sense the water body data in the environment where the sampling device 100 is located, such as water pressure, and then transmit these data to the monitoring terminal 310. When the operator determines that the current depth of the sampling device 100 is the target depth for sampling through the data transmitted back, the water body is sampled through the sampling device 100, and accurate sampling can be achieved.
