The valve 1-2 and the piston 1-3, the casing 1-1 is fixedly connected with a connecting rod with a scale, the bottom of the casing 1-1 is provided with a first through hole, and the one-way valve 1- 2 is located at the first through hole, the piston 1-3 is located inside the housing 1-1 and above the one-way valve 1-2, the piston 1-3 and the lower end of the piston push-pull rod 1-4 Fixed connection, the upper end of the piston push-pull rod 1-4 is connected with a traction rope 2, the piston push-pull rod 1-4 is also sleeved with a second spring 9, and the top of the housing 1-1 is provided with a The second through hole 1-5 through which the piston push-pull rod 1-4 passes, the inner side wall of the second through hole 1-5 is provided with a plurality of guide grooves 1-51 along the circumferential direction. Each is provided with a first spring 1-52, the first spring 1-52 is fixedly connected with a snap joint 3-2, and one end of the piston push-pull rod 1-4 close to the piston 1-3 is provided with a snap joint 3-2. 2 Matching snap slots 3-1.

In this embodiment, when taking water from rivers at different water levels and depths, first connect the shell 1-1 of the water taking mechanism 1 to the connecting rod with a scale. Because the density of the water taking mechanism 1 itself is greater than that of water, the water taking mechanism 1. It can sink in the water and will not float on the water surface. The water intake mechanism 1 is fixed at the specified water level through the connecting rod. In order to enable the water intake mechanism 1 to take water at different depths of the river and to ensure that the water intake mechanism 1 is accurate at different depths of the river. Therefore, a first through hole is provided at the bottom of the casing 1-1, and the one-way valve 1-2 is set at the first through hole and communicates with the interior of the casing 1-1. In order to avoid the water intake mechanism 1 Before the inner piston 1-3 sinks to the target water level, the piston 1-3 may move upward due to the pressure of the external water pressure and enter the housing 1-1. First, place the piston 1-3 on the piston push-pull rod. Driven by 1-4, it is fixed to the one-way valve 1-2, the piston 1-3 is blocked by the water inlet hole of the one-way valve 1-2, and a sufficiently long first is sleeved on the piston push-pull rod 1-4. The length of the second spring 9 and the second spring 9 matches the length of the piston push-pull rod 1-4 in the housing 1-1 when the piston 1-3 is set above the one-way valve 1-2, and this setting can make the water intake In the process of sinking to the specified water level, the mechanism 1 can be used to offset the force of the water pressure acting on the pistons 1-3, so that the water in the river will not flow along the water inlet during the process of positioning the water intake mechanism 1 to different depths in the river. Enter the inside of the shell 1-1, so that the sampling mechanism 1 can take samples at different depths in the river, and also ensures the accuracy of the sampling. After reaching the target water level, the connecting rod fixes the water intake mechanism 1, and pulls the traction rope 2. , because the piston 1-3 is fixedly connected with the piston push-pull rod 1-4, and the top of the piston push-pull rod 1-4 is connected by the traction rope 2, so the pulling force of the traction rope 2 is greater than the elastic force of the second spring, the piston push-pull rod 1-4 Drive the piston 1-3 to move from bottom to top along the inner side wall of the housing 1-1. The water in the river enters from the bottom of the housing 1-1 with a water inlet to complete the water intake. In order to ensure that the piston pushes and pulls the rod 1-4 When taking water, the elastic force of the second spring will not cause the piston 1-3 to slide down, which will affect the water intake. Therefore, the card joint 3-2 and the card slot 3-1 can be distributed in a plurality of equal intervals and symmetrical distribution.

On the end near pistons 1-3, move to the shell When the top of the body 1-1, the through hole 1-5 is provided with a clamping joint 3-1 for fixing the clamping groove 3-1 provided on the piston push-pull rod 1-4, and the clamping groove 3-1 is connected with the clamping joint 3-1. 2 After the snap connection, the sliding of the piston push-pull rod 1-4 is avoided, the piston 1-3 stops moving, the one-way valve 1-2 is automatically closed, and the water sample is isolated from the outside world to ensure accurate water intake, and in the process of water intake To always make the pulling force acting on the traction rope greater than the elastic force of the second spring, when the water intake mechanism 1 is used in winter, the river is affected by the season and the environment in winter. The diameter of the water intake mechanism can be set to a small size, which is convenient for water intake in winter rivers.

In order to enable the water intake mechanism to be used in any season of the year, especially in winter due to the influence of geographical environmental factors, the river water intake device is easy to freeze.
