[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figures 1 to 5 As shown, a water sample collector described in an embodiment of the utility model comprises a support rod 1; two brackets 11 are fixedly connected to the ends of the support rod 1, and a sampling barrel 12 is fixedly connected to the ends of the two brackets 11. A plurality of groups of first through holes 13 are provided in the middle of the sampling barrel 12, and two of the first through holes 13 form a group, and the two groups of the first through holes 13 are arranged opposite to each other. A sampling cover 14 is slidably connected to one end of the support rod 1 close to the sampling barrel 12, and a pull rod 15 is fixedly connected to the top of the sampling cover 14, and a pull rod 15 is fixedly connected to the middle of the sampling cover 14. There are two first springs 16, the other end of the first spring 16 is fixed to the bottom of the sampling barrel 12, the two first springs 16 are fixed to the inside of the sampling barrel 12, the bottom of the sampling cover 14 is fixed to two baffles 17, the two baffles 17 are arranged oppositely, the baffles 17 are fixed to the positions corresponding to the two groups of first through holes 13, and the middle of the baffle 17 has two second through holes 18. When working, the sampling barrel 12 is placed in the river water of the specified depth by holding the end of the support rod 1, and then the pull rod 15 is pulled upward. The sampling cover 14 is moved to slide in the middle of the support rod 1. When the sampling cover 14 moves upward, the water sample enters the sampling barrel 12 from the top for collection. When the sampling cover 14 moves upward, the positions of the plurality of second through holes 18 and the plurality of first through holes 13 coincide, and the water sample enters the sampling barrel 12 from the middle of the first through holes 13. After the pull rod 15 is loosened, the sampling cover 14 is reset by contraction of the two first springs 16, so that the sampling cover 14 moves downward to store the water sample. The second through holes 18 and the first through holes 13 can effectively enable the water sample to enter the sampling barrel 12 more quickly, effectively reduce the negative pressure generated when the water sample enters from the top, resulting in incomplete water sample collection, effectively reduce the problem of bubbles caused by the pressure generated when the water sample enters the sampling barrel 12, effectively reduce the space occupied by bubbles in the sampling barrel 12, effectively reduce the generation of bubbles, make the water sample amount more accurate, thereby effectively improving the accuracy of the measurement result, and make it more convenient to collect water samples, and simple to use and operate.
[0025] like Figure 1 and Figure 3 As shown, the side wall of the baffle 17 is fixedly connected with a mesh plate 2, and the side wall of the sampling barrel 12 is fixedly connected with two support frames 21, and the two support frames 21 are arranged opposite to each other. The support frames 21 are fixedly connected to the corresponding positions of the baffle 17, and multiple groups of bristles 22 are fixedly connected inside the support frames 21. The ends of the multiple groups of bristles 22 are in contact with the surface of the mesh plate 2. When working, when the water sample passes through the second through hole 18 and the first through hole 13 and enters the sampling barrel 12, the mesh plate 2 filters the impurities in the water sample. When the baffle 17 moves, the impurities in the water sample are filtered through the multiple groups of bristles. The bristles 22 clean the impurities filtered on the surface of the mesh plate 2. The mesh plate 2 can effectively reduce the entry of impurities and large particles into the sampling barrel 12, and effectively reduce the wear of the surface caused by impurities and large particles in the sampling barrel 12.

[0026] like Figure 1 and Figure 5 As shown, a filter screen 3 is fixedly connected to the bottom of the sampling cover 14, and the other end of the filter screen 3 is fixedly connected to the side wall of the sampling barrel 12. The filter screen 3 is fixedly connected between the baffle 17 and the sampling barrel 12. Two first magnets 31 are fixedly connected to the side wall of the sampling barrel 12, and the two first magnets 31 are arranged oppositely. Two second magnets 32 are fixedly connected to the middle of the filter screen 3, and the two second magnets 32 are fixedly connected to the positions of the corresponding two second magnets 32. The first magnets 31 and the second magnets 32 repel each other when they are close to each other. During operation, when the sampling cover 14 moves upward, the filter screen 3 is pulled up at the same time, and when the water sample enters the interior from the top of the sampling barrel 12, impurities are filtered through the filter screen 3, and the sampling When the cover 14 moves downward, the filter 3 repels each other when the first magnet 31 and the second magnet 32 are close to each other, so that the filter 3 moves to the outside of the sampling barrel 12. The impurities can be effectively filtered out by the filter 3, which can effectively increase the purity of the collected water sample, effectively reduce the interference of impurities and suspended matter in the water sample on water quality detection, and effectively increase the accuracy and reliability of the water sample detection results. The first magnet 31 and the second magnet 32 can effectively reduce the accumulation of the filter 3 between the sampling cover 14 and the sampling barrel 12 when the sampling cover 14 contacts the sampling barrel 12, and effectively reduce the problem of damage caused by squeezing the filter 3 between the sampling cover 14 and the sampling barrel 12.
[0027] like Figure 1As shown, there are two limit blocks 4 in the middle of the support rod 1, and the two limit blocks 4 are arranged opposite to each other. A second spring 41 is fixedly connected to the bottom of the limit block 4, and a rubber pad 42 is fixedly connected to the end of the second spring 41. During operation, when the pull rod 15 is stretched upward to move the sampling cover 14, the top of the rubber pad 42 contacts the top of the sampling cover 14, and the sampling cover 14 is blocked after the second spring 41 is contracted. After the pull rod 15 is released, the sampling cover 14 is elastically reset by the second spring 41 to make the sampling cover 14 rebound downward. The sampling cover 14 can be effectively positioned by the limit block 4, and the instability problem caused by excessive stretching of the sampling cover 14 is effectively reduced. The sampling cover 14 can be pushed downward by the second spring 41 to effectively increase the smoothness of the sampling cover 14. The contact between the rubber pad 42 and the sampling cover 14 can effectively reduce the friction generated on the sampling cover 14, and can effectively reduce the wear on the surface of the sampling cover 14 caused by friction.
[0028] like Figure 1 and Figure 2 As shown, the bottom of the sampling barrel 12 is fixedly connected to the cone block 5, and the surface of the cone block 5 is threaded. During operation, when collecting water samples at the lowest depth, the cone block 5 is inserted into the bottom soil from the bottom, and the cone block 5 is rotated to fix the cone block 5 in the soil. The cone block 5 can effectively make the sampling barrel 12 more stable during the process of collecting water samples, and can effectively reduce the problem of shaking or displacement caused by water flow. Inserting the cone block 5 into the bottom of the river channel can make the sampling barrel 12 more firmly attached to the bottom of the river channel, effectively reducing the situation where the water flow is washed away. Stable sampling barrel 12 can effectively reduce the problem of turbidity of bottom water samples caused by water flow impact.
[0029] like Figure 5 As shown, the side wall of the sampling cover 14 is fixedly connected with multiple groups of elastic plates 6, and the multiple groups of elastic plates 6 are equidistantly distributed on the inner wall of the sampling cover 14, and the elastic plates 6 are arranged in an arc shape. During operation, when the sampling cover 14 moves downward, when the top of the sampling barrel 12 contacts the multiple groups of elastic plates 6, the multiple groups of elastic plates 6 are squeezed and elastically bent, so that the middle part of the sampling cover 14 covers the end of the sampling barrel 12, and the multiple groups of elastic plates 6 can effectively make the sampling barrel 12 enter the middle part of the sampling cover 14 more smoothly, and the elastic plates 6 can effectively reduce the deviation caused by the downward reset of the sampling cover 14, and the multiple groups of elastic plates 6 can guide the sampling barrel 12 to enter the middle part of the sampling cover 14, and the elastic plates 6 can make the sampling cover 14 and the sampling barrel 12 fit more closely, thereby effectively increasing the stability of the sampling cover 14.
[0030] like Figure 4As shown, a sealing ring 7 is fixedly connected to the middle part of the sampling cover 14, and the side wall of the sealing ring 7 is in contact with the surface of the support rod 1. When working, the sealing ring 7 is squeezed between the sampling cover 14 and the support rod 1 to form a sealing isolation layer. The sealing ring 7 can effectively increase the sealing effect and effectively reduce the entry of water at different depths when the water sample is collected from the river channel. The effective increase in sealing performance can reduce the outflow of water samples, reduce the problem of insufficient flow collection caused by the outflow of water samples, and effectively reduce the accuracy of water quality detection.
[0031] During operation, the sampling barrel 12 is placed in the river water at a specified depth by holding the end of the support rod 1, and then the pull rod 15 is pulled upward to make the sampling cover 14 slide in the middle of the support rod 1. When the sampling cover 14 moves upward, the water sample enters the interior from the top of the sampling barrel 12 for collection. When the sampling cover 14 moves upward, the positions of the multiple groups of second through holes 18 coincide with the positions of the multiple groups of first through holes 13, and the water sample enters the sampling barrel 12 from the middle of the first through holes 13. After the pull rod 15 is released, the sampling cover 14 is reset by contraction of the two first springs 16, so that the sampling cover 14 moves downward to store the water sample. When the water sample enters the sampling barrel 12 through the second through holes 18 and the first through holes 13, the mesh plate 2 filters impurities in the water sample. When the baffle 17 moves, the impurities filtered on the surface of the mesh plate 2 are cleaned by the multiple groups of bristles 22. When the sampling cover 14 moves upward, the filter screen 3 is pulled up at the same time, and the water sample enters from the top of the sampling barrel 12 When the sampling cover 14 is inside, impurities are filtered through the filter screen 3. When the sampling cover 14 moves downward, the filter screen 3 repels each other when the first magnet 31 and the second magnet 32 are close to each other, so that the filter screen 3 moves to the outside of the sampling barrel 12. When the pull rod 15 is stretched upward to move the sampling cover 14, the top of the rubber pad 42 contacts the top of the sampling cover 14, and the sampling cover 14 is blocked after the second spring 41 is contracted. After the pull rod 15 is released, the sampling cover 14 is elastically reset by the second spring 41 to make it bounce back downward. When collecting water samples at the lowest depth, the cone block 5 is inserted from the bottom into the bottom soil and rotated to fix the cone block 5 in the soil. When the sampling cover 14 moves downward, when the top of the sampling barrel 12 contacts the multiple groups of elastic plates 6, the multiple groups of elastic plates 6 are squeezed and elastically bent, so that the middle part of the sampling cover 14 covers the end of the sampling barrel 12, and is squeezed between the sampling cover 14 and the support rod 1 through the sealing ring 7, and a sealing isolation layer is formed through the sealing ring 7.
