Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6, a water quality monitoring sampling device, includes sample box 6, it has a plurality of sample chamber 601 to be circular equidistant distribution on the sample box 6, be equipped with sample connection 3 and sampling tube 4 on the lateral wall at both ends about sample chamber 601, the upper and lower face of sample box 6 is fixed with upper cover 7 and lower cover 5 through the bolt respectively, install motor 2 respectively for the position department of sample chamber 601 on the upper cover 7, the output shaft and the drive shaft 9 one end fixed connection of motor 2, drive shaft 9 rotates and sets up in sample chamber 601, sealed apron 10 is all installed at both ends about drive shaft 9.

The motor is characterized in that an armored cable 1 is fixed on the upper cover 7, one end of the armored cable 1 is electrically connected with the motor 2, the other end of the armored cable 1 is connected with the storage battery through a control switch, and scales are further arranged on the outer wall of the armored cable 1. Through observing the scale on the armoured cable 1, the submergence degree of depth of convenient control sampling device reaches appointed degree of depth collection water sample, utilizes the control switch of the 1 other end of armoured cable, and every switch and 2 one-to-one of motor control every motor 2 respectively to realize sampling the water in the different time, perhaps realize the water sampling of different degree of depth positions after adjusting the submergence degree of depth.

The sampling cavity 601 is composed of a middle cavity and two end expansion cavities, and the sealing cover plate 10 is located in the expansion cavities. The inner diameter of the middle section cavity is smaller than that of the expansion cavity to form a cylindrical cavity with wider two ends and narrow middle, and the upper sampling port 3 and the sampling tube 4 are respectively positioned in the expansion cavities at the upper end and the lower end and are communicated with the outside.

The sealing cover plate 10 comprises a fixing plate 101 and a sealing gasket 102 adhered to the surface of the fixing plate 101, the fixing plate 101 is connected with the driving shaft 9 through threads, and a protrusion 103 is integrally arranged on the periphery of the fixing plate 101. Through the rotation of drive shaft 9, utilize the screw thread to promote sealed apron 10 and move down to seal the midrange cavity, acquire the water sample. The two ends of the terminal cavity are sealed by the gasket 102 to prevent sample leakage. The inner wall of the expansion cavity of the sampling cavity 601 is provided with a sliding groove which is matched with the bulge 130, so that the sealing cover plate 10 can move up and down under the rotation of the driving shaft 9.

The drive shaft 9 is composed of a middle section 902 and threaded sections 901 at two ends, and the thread directions of the threaded sections 901 at the two ends are opposite. The diameter of the middle section 902 is larger than the threaded sections 901 at the two ends, and when the sealing cover plate 10 contacts the end of the middle section 902, the two ends of the middle section 902 are sealed by the sealing gasket 102, so that sample leakage at the driving shaft 9 is avoided.

And a balancing weight 8 is welded on the lower cover 5.

Specifically, when the water sampling device is used, the motor 2 is controlled to rotate, so that the sealing cover plate 10 seals the middle section cavity in each sampling cavity 601, the device is placed in water above a sampling point, the armored cable 1 is dragged and dropped, the submergence depth of the sampling device is determined through the scale marks on the armored cable 1, the water sampling device is stabilized for 3-5 seconds after reaching the specified depth, the motor 2 is started by using the control start end, the motor drives the sealing cover plate 10 on the driving shaft 9 to move towards the two ends of the sampling cavity 601, so that a water sample is obtained by using the upper sampling port 3 and the sampling pipe 4, the motor 2 is started after waiting for 5-10 seconds, the water in the middle section cavity in the sampling cavity 601 is sealed by using the sealing cover plate 10, the sampling depth and the sampling time of the sampling cavity 601 corresponding to the motor 2 are recorded in sequence, the water sampling operation is completed, when water samples of other depths, by adjusting the application length of the armored cable 1.

When the water sample needs to be taken out, the control switch is utilized to control the motor 2 to rotate, the water sample automatically flows out through the sampling tube 4, and the water sample is stored by using a container.
