[0002] The water environment specifically refers to the space in nature composed of water, including rivers, lakes, seas, as well as man-made reservoirs, ponds, swamps, and glaciers. It is the water body surrounding human activity space or affecting people's work and development, and has extremely high research value. While people use the water environment, they must also maintain its quality and hygiene.

[0003] In order to obtain timely information about the condition of the water area, sampling devices can be installed on the riverbank to draw liquid into the device as a sample. The sample is then transported by staff to the testing institute for analysis of the liquid composition, and then a treatment plan can be formulated. However, the previous sampling devices were often fixed at different heights, making it difficult to draw liquid samples of different depths and conduct comparative experiments with multiple sets of data.

[0004] Now, a novel sampling device with a telescopic structure for water environment management is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for water environment management with a telescopic structure, so as to solve the problem of fixed sampling depth mentioned in the background art.

[0007] As a further technical solution of this utility model, the upper part of the hose is embedded in the limiting sleeve, and the bottom of the output end of the motor is fixedly connected to the lead screw.

[0008] As a further technical solution of this utility model, a frame is fixed to the upper right corner of the outer shell, and a rotating disk is movably connected to the center of the lower part of the frame. The rotating disk has grooves on the front, back, left and right sides, and a sample box is fixed in the groove. A rotating frame is movably connected to the upper left corner of the outer shell, and a liquid pump is fixed to the top of the upper right corner of the rotating frame. The liquid pump is fixedly connected to a hose. A liquid outlet pipe is installed at the bottom of the upper right corner of the rotating frame. A second motor is installed on the right side inside the shell.

[0009] As a further technical solution of this utility model, the liquid outlet pipe is connected to the liquid pump and the hose, and the top of the output end of the second motor is fixedly connected to the rotary table.

[0010] As a further technical solution of this utility model, a storage groove is provided on the left side inside the shell, a cylinder is fixed to the top of the shell, and a movable plate is fixed to the bottom of the piston rod of the cylinder. Slots are provided on the left and right sides inside the movable plate. Limit rods are fixed on the top two sides of the storage groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4An embodiment of this utility model provides a water environment management sampling device with a telescopic structure, including a housing 1, a hanger 2 fixed to the upper left corner of the outer side of the housing 1, a limit sleeve 3 fixed to the center of the top of the hanger 2, a vertical frame 5 fixed to the left side of the hanger 2, a motor 4 fixed to the top of the outer side of the vertical frame 5, a lead screw 6 movably connected between the upper and lower parts of the inner side of the vertical frame 5, a threaded block 10 threadedly connected to the outer side of the lead screw 6, a lifting frame 9 fixed to the left side of the threaded block 10, a liquid extraction gun 8 vertically fixed to the lower left corner of the lifting frame 9, and a hose 7 fixed to the top of the liquid extraction gun 8.

[0023] The upper part of the hose 7 is embedded in the limiting sleeve 3, and the bottom of the output end of the motor 4 is fixedly connected to the lead screw 6;

[0024] Specifically, such as Figure 1 and Figure 2 As shown, after the device is moved to the sampling position, the motor 4 is started to rotate the lead screw 6, and the threaded block 10 connected to the lead screw 6 is moved longitudinally along the inner wall of the vertical frame 5. The lifting frame 9 on the left side of the threaded block 10 is guided to move together until the liquid suction gun 8 is inserted into the sampling position. Then the liquid pump 21 is started and the sample liquid is drawn through the hose 7 and injected into the sample box 19.

[0025] A frame 16 is fixed to the upper right corner of the outer shell 1, and a rotating disk 17 is movably connected to the center of the lower part of the frame 16. The rotating disk 17 has grooves 18 on the front, back, left and right sides, and a sample box 19 is fixed in the grooves 18. A rotating frame 20 is movably connected to the upper left corner of the outer shell 16, and a liquid pump 21 is fixed to the top of the upper right corner of the rotating frame 20. The liquid pump 21 is fixedly connected to the hose 7. A liquid outlet pipe 22 is installed at the bottom of the upper right corner of the rotating frame 20. A motor 25 is installed on the right side inside the shell 1. The liquid outlet pipe 22 is connected to the liquid pump 21 and the hose 7. The top of the output end of the motor 25 is fixedly connected to the rotating disk 17.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, after starting motor 15, rotate the rotating disk 17 in the frame 16 and adjust the position of the groove 18 in the rotating disk 17. Whenever the groove 18 rotates to the left, the cover of the sample box 19 inside the groove 18 opens in advance. The liquid pump 21 injects the sample liquid extracted from different depths into the sample box 19 through the liquid outlet pipe 22 for separate collection. Then the sample box 19 is covered to prevent the sample from splashing out.

[0027] A storage slot 24 is provided on the left side inside the housing 1. A cylinder 25 is fixed to the top of the housing 1. A movable plate 34 is fixed to the bottom of the piston rod of the cylinder 25. Slots 27 are provided on the left and right sides inside the movable plate 34. Limit rods 26 are fixed to the top of the storage slot 24 on both sides. A positioning block 30 is fixed to the left side outside the housing 1. A support rod 28 is movably inserted into the positioning block 30. A screw hole 29 is provided between the top and bottom of the surface of the support rod 28. A bolt 31 is threaded to the front end of the positioning block 30. A bracket 23 is fixed to the right side of the support rod 28, and a motor 32 is fixed to the top of the bracket 23. A guide wheel 33 is movably connected between the upper and lower parts inside the bracket 23. A clamping plate 11 is horizontally fixed to the bottom of the support rod 28. Two sets of frames 13 are installed on the surfaces of the clamping plate 11 and the movable plate 34. Rollers 12 are movably connected between the left and right parts inside the frame 13. A riverbank 14 is provided between the clamping plate 11 and the movable plate 34. The bottom of the output end of the motor 32 is fixedly connected to the guide wheel 33. The bottom of the limiting rod 26 is embedded in the slot 27.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the support rod 28 embedded in the positioning block 30 connects the housing 1 and the clamping plate 11. After the screw hole 29 is aligned, the rotating bolt 31 is locked. The piston rod of the cylinder 25 pushes the movable plate 34, so that the roller 12 mounted on its surface fits against the riverbank 14. The roller 12 on the surface of the clamping plate 11 can maintain the stability of the device when it moves. After starting the motor 32, the guide wheel 33 in the rotating bracket 23 can move the sampling device along the riverbank 14.

[0029] Furthermore, motor 4, motor 15, motor 32 and cylinder 25 are all electrically connected to an external PLC control module to control the opening and closing of motor 4, motor 15, motor 32 and cylinder 25 and preset relevant parameters. The electrical connection relationship and control method between them are existing technologies, so they will not be described in detail.

[0030] Furthermore, the cylinder 25 includes a cylinder barrel, piston, piston rod, end cap, seal, solenoid valve, air source and air passage. The cylinder 25 is a fully disclosed prior art, and the air supply method is implemented in a conventional manner, so it will not be described in detail.

[0031] Working principle: When using this utility model, firstly, the support rod 28 embedded in the positioning block 30 connects the housing 1 and the clamping plate 11. After aligning with the screw hole 29, the rotating bolt 31 is locked. The piston rod of the cylinder 25 pushes the movable plate 34, causing the rollers 12 mounted on its surface to fit against the riverbank 14. The rollers 12 on the surface of the clamping plate 11 help maintain the stability of the device when moving. After starting the motor 32, the guide wheel 33 in the bracket 23 is rotated, and the sampling device can be moved along the riverbank 14. After the device is moved to the sampling position, the motor 4 is started to rotate the lead screw 6, which moves longitudinally along the inner wall of the vertical frame 5. The threaded block 10 connected to the external of the movable lead screw 6 guides the lifting frame 9 on the left side of the threaded block 10 to move together until the liquid suction gun 8 is inserted into the sampling position. Then, the liquid pump 21 is started and the sample liquid is drawn into the sample box 19 through the hose 7. At this time, the motor 2 15 needs to be started to rotate the rotating disk 17 in the frame 16 and adjust the position of the groove 18 in the rotating disk 17. Whenever the groove 18 is rotated to the left, the cover of the sample box 19 inside the groove 18 is opened in advance. The liquid pump 21 injects the sample liquid extracted at different depths into the sample box 19 through the liquid outlet pipe 22 for separate collection. Then the sample box 19 is covered.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
