Existing automatic water sampling devices for water body monitoring are mostly for sandy rivers, ocean water quality and enterprise sewage and wastewater discharge, etc., and are not suitable for the collection of farmland soil water.

[0003] The prior art discloses an automatic continuous water sample collection device, with the announcement number CN204903217U, including a water collector, a plurality of filter stabilizing plates are arranged from top to bottom inside the water collector; a water tank connected to the lower end of the water collector through a connecting pipe, the connecting pipe is connected to the upper end of the water tank, a water tank overflow hole is arranged at the upper end of the side wall of the water tank, and multiple rows of fixtures are arranged inside the water tank from bottom to top, and the vertical distance between the lowermost fixture in the upper row and the uppermost fixture in the lower row of two adjacent rows of fixtures is equal to the vertical distance between the two adjacent fixtures in the same row. The above-mentioned prior art adopts the method of flooding for sampling, but when the water overflows the sampling bottle, it will enter the sampling bottle from the air outlet box water inlet, thereby slowing down the speed of internal gas discharge and also reducing the sampling speed.

[0004] Therefore, the utility model provides a continuous automatic water sample collection device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 5 As shown, this embodiment provides a continuous automatic water sample collection device, including a water tank 1, a water inlet pipe 3 is connected to the side wall of the water tank 1, a support frame 4 is fixedly connected in the water tank 1, and a plurality of sampling bottles 5 are detachably connected to the support frame 4, a through groove 11 is provided on the top of the sampling bottle 5, a round block 6 is fixedly connected in the through groove 11, a through hole 7 is provided in the center of the round block 6, a floating plate 12 is provided under the round block 6, the floating plate 12 is detachably connected to the through groove 11, the floating plate 12 is adapted to the round block 6, a sealing component is fixedly connected to the bottom surface of the floating plate 12, the bottom of the sealing component extends out of the sampling bottle 5, a water inlet 16 is provided at the bottom of the sampling bottle 5, and the sealing component is detachably connected to the water inlet 16.

[0024] The support frame 4 is arranged in a stepped manner, and the positions of each sampling bottle 5 are also fixed in sequence from low to high. When in use, farmland irrigation water enters the water tank 1 from the water inlet pipe 3, and the water level in the water tank 1 rises slowly. When the water level is above the bottom of the sampling bottle 5 at the lowest position, water enters from the water inlet 16 at the bottom of the sampling bottle 5, squeezing the air in the sampling bottle 5, and the air is discharged from the through hole 7 at the top of the sampling bottle 5. The water level in the sampling bottle 5 continues to rise, and when it contacts the float plate 12, the float plate 12 moves upward due to the buoyancy of the water. When the sampling bottle 5 is filled with water, the float plate 12 just moves upward to the through groove 11 and The round block 6 fits in place to block the through hole 7, and the sealing assembly blocks the water inlet 16 below to complete the automatic sealing. This arrangement can increase the sampling speed, ensure that the water can enter the sampling bottle 5 normally and without obstruction, and improve work efficiency. When testing the water in the sampling bottle 5, it is only necessary to take out the sampling bottle 5 on the support frame 4, and press the floating plate 12 downward to move the bottom counterweight 15 downward, so that the water inlet 16 is opened, and the water naturally flows out from the bottom of the sampling bottle 5, which is convenient for testing. After all the water flows out, the floating plate 12 and the counterweight 15 fall naturally, which is convenient for next use. The overall structure of the utility model is simple and convenient, and it is very convenient to use. It can also make the water enter the sampling bottle 5 more stably, reduce the resistance during sampling, and improve the sampling efficiency.

[0025] Further optimized solution, the sealing assembly includes a connecting rod 13 symmetrically fixed to the bottom surface of the floating plate 12, the bottom of the connecting rod 13 passes through the sampling bottle 5 and is slidably connected to the sampling bottle 5, and a counterweight 15 is fixed to the bottom surface of the connecting rod 13, and the counterweight 15 is detachably connected to the bottom of the water inlet 16. When the floating plate 12 moves upward, it drives the connecting rod 13 to move upward, and the connecting rod 13 drives the counterweight 15 to move upward. When the floating plate 12 blocks the through hole 7, the counterweight 15 just blocks the water inlet 16, so that the sampling bottle 5 remains sealed and the sampling work is completed.

[0026] Further optimizing the scheme, a groove 14 is provided at the bottom of the sampling bottle 5, the groove 14 is connected to the water inlet 16, and the groove 14 is adapted to the counterweight 15. The setting of the groove 14 facilitates the counterweight 15 to be just stuck into the bottom of the sampling bottle 5, ensuring sealing and preventing water leakage.

[0027] In a further optimized solution, a sliding rod 9 is symmetrically fixed to the top surface of the floating plate 12, and the top of the sliding rod 9 passes through the round block 6 and is slidably connected to the round block 6. The setting of the sliding rod 9 ensures the stability of the floating plate 12 when it moves upward, and there will be no deviation, so it can be reused.

[0028] In a further optimized solution, T-slots 8 are symmetrically provided on the round block 6, and the sliding rod 9 is located in the T-slots 8 and is slidably connected to the T-slots 8. The T-slots 8 facilitate the movement of the sliding rod 9, and when the floating plate 12 contacts the round block 6, the sliding rod 9 blocks the T-slots 8, thereby improving the overall airtightness.

[0029] Further optimizing the scheme, the top surface of the sliding rod 9 is fixedly connected to a limit plate, and the limit plate is slidably connected to the T-slot 8. The setting of the limit plate can prevent the sliding rod 9 and the floating plate 12 from falling naturally, so that the floating plate 12 maintains a certain position, and improves practicality.

[0030] In a further optimized solution, a plug 10 is fixed to the top surface of the floating plate 12, and the plug 10 is adapted to the through hole 7. When the floating plate 12 is inserted into the through groove 11 and contacts the round block 6, the plug 10 is first inserted into the through hole 7 to block the through hole 7, thereby ensuring the airtightness of the structure.

[0031] In a further optimized solution, a filter box 2 is fixedly connected to and communicated with the side wall of the water tank 1, and a side of the filter box 2 away from the water tank 1 is fixedly connected to and communicated with the water inlet pipe 3. The filter box 2 can filter out some impurities in the water and improve the accuracy of the detection result.
