The end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the cleaning plate.

[0008] The brush bristles are fixedly installed on the arc surface of the cleaning plate near the collector, and an elastic sheet is fixedly installed on the arc surface of the cleaning plate.

[0009] Preferably, the promoting mechanism includes a rubber strip, which is fixedly installed on the arc surface of the collector, and the arc surface of the rubber strip has a groove.

[0010] Preferably, the groove is arc-shaped, and there are several grooves, which are evenly arranged in an array on the arc surface of the rubber strip.

[0011] Preferably, the cleaning plate is arc-shaped, and the shape of the cleaning plate is adapted to the arc surface of the collector, so that the cleaning plate can fit the surface of the filter screen on the collector for cleaning.

[0012] Preferably, the cleaning plate has a circular hole on its side wall, and the cleaning plate is fitted onto the arc surface of the straight rod, so that the straight rod can rotate on the arc surface of the straight rod.

[0013] Preferably, the elastic sheet is in the shape of a thin rope and is disposed between adjacent bristles, so that the elastic sheet can limit the bristles when they contact the surface of the filter screen, causing the bristles to deform and drop off impurities.

[0014] Preferably, the shape of the sealing block is adapted to the shape of the filter screen, and the arc surface of the sealing block is provided with an installation groove. The shape of the installation groove is adapted to the shape of the straight rod, which facilitates the installation of the straight rod.

[0015] Compared with the prior art, this utility model provides a water quality sampling device that is easy to adjust the depth, and has the following beneficial effects:

[0016] 1. This water sampling device, which facilitates depth adjustment, is equipped with an adjustable rotating roller. The connecting rope on the rotating roller moves to adjust the position of the sampler. When the sampler reaches the designated position, the electric push rod is activated, which moves the sealing block to collect samples from the inside of the sampler. Adjusting the electric push rod causes the cleaning plate to adhere to the surface of the filter screen under the action of the torsion spring. The bristles clean the impurities on the filter screen. The elastic sheet limits the bristles when they contact the surface of the filter screen, causing the bristles to deform and dislodge the impurities, ensuring the permeability of the filter screen and facilitating water sample collection.

[0017] 2. This water quality sampling device, which facilitates depth adjustment, is equipped with a facilitating mechanism. As the cleaning plate moves, the bristles on the cleaning plate come into contact with the rubber strip and groove, which facilitates the cleaning of impurities on the bristles, thereby making it easier for the cleaning plate to clean the filter screen next time.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a water quality sampling device that facilitates depth adjustment, including a body 1. A rotating roller 2 is rotatably connected to the side wall of the body 1 via a fixed plate. A connecting rope 5 is fixedly connected to the arc surface of the rotating roller 2. A collector 6 is fixedly connected to the end of the connecting rope 5 away from the arc surface of the rotating roller 2. An electric push rod 7 is fixedly installed on the upper surface of the collector 6. A sealing block 8 is fixedly installed at the movable end of the electric push rod 7. A filter screen 9 is fixedly installed on the arc surface of the collector 6. A cleaning mechanism 3 is provided on the outside of the collector 6. A promoting mechanism 4 is provided on the outside of the collector 6. The cleaning mechanism 3 includes a straight rod 301, a torsion spring 302, a cleaning plate 303, bristles 304, and an elastic sheet 305.

[0024] In one embodiment of this utility model, a straight rod 301 is fixedly installed on the surface of the sealing block 8, a torsion spring 302 is fixedly installed on the arc surface of the straight rod 301, one end of the torsion spring 302 away from the arc surface of the straight rod 301 is fixedly connected to the inner wall of the cleaning plate 303, bristles 304 are fixedly installed on the arc surface of the cleaning plate 303 near the collector 6, and an elastic sheet 305 is fixedly installed on the arc surface of the cleaning plate 303.

[0025] In addition, the promoting mechanism 4 includes a rubber strip 401, which is fixedly installed on the arc surface of the collector 6. The arc surface of the rubber strip 401 has a groove 402. The groove 402 is arc-shaped, and there are several grooves 402, which are evenly arranged on the arc surface of the rubber strip 401.

[0026] In this embodiment of the invention, the cleaning plate 303 is arc-shaped, and its shape is adapted to the arc surface of the collector 6, allowing the cleaning plate 303 to adhere to the surface of the filter screen 9 on the collector 6 for cleaning. A circular hole is provided on the side wall of the cleaning plate 303, and the cleaning plate 303 is fitted onto the arc surface of the straight rod 301, allowing the straight rod 301 to rotate on its arc surface. The elastic sheet 305 is rope-shaped and is disposed between adjacent bristles 304, allowing the elastic sheet 305 to limit the bristles 304 when they contact the surface of the filter screen 9, causing the bristles 304 to deform and dislodge impurities. The shape of the sealing block 8 is adapted to the shape of the filter screen 9. The arc surface of the sealing block 8 is provided with an installation groove, the shape of which is adapted to the shape of the straight rod 301, which facilitates the installation of the straight rod 301.

The lower end of the collector 6 is detachably snapped with a sealing plug to facilitate the subsequent removal of water samples and to facilitate the submersion of the heavier collector 6 in the water. The sealing block 8 fills and seals the filter screen 9 to prevent the leakage of water samples.

[0027] In this utility model, during use, the connecting rope 5 on the rotating roller 2 is moved to adjust the position of the collector 6. When it reaches the designated position, the electric push rod 7 is activated to drive the sealing block 8 to move, thereby collecting samples from the inside of the collector 6. The electric push rod 7 is adjusted so that the cleaning plate 303 adheres to the surface of the filter screen 9 under the action of the torsion spring 302. The bristles 304 clean the impurities on the filter screen 9. The elastic sheet 305 can limit the bristles 304 when they contact the surface of the filter screen 9, causing the bristles 304 to deform and drop the impurities, ensuring the permeability of the filter screen 9 and facilitating the collection of water samples.

[0028] As the cleaning plate 303 moves, when the bristles 304 on the cleaning plate 303 come into contact with the rubber strip 401 and the groove 402, it promotes the cleaning of impurities on the bristles 304, thereby facilitating the cleaning plate 303 to clean the filter screen 9 next time.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
