Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a water stratified sampling ware, combines fig. 1 and fig. 2, includes the thief rod 1 of being made by stainless steel material, is cavity column structure in the thief rod 1, and thief rod 1 is inside along three horizontally baffle 13 of length direction fixedly connected with, and three baffle 13 is along 1 length direction interval evenly distributed of thief rod, falls into four sampling chambers 11 with thief rod 1. Each sampling chamber 11 is provided with a water inlet 111 and a water outlet 112, the water inlet 111 is connected with a water baffle 2, and the water outlet 112 is in threaded connection with a water stop 1121. The bottom end of the sampling rod 1 is fixedly connected with a conical boss 12.

After the sampling rod 1 is vertically inserted into water, the boss 12 can reduce the disturbance of water flow and reduce the mutual mixing of water with different depths. Then, the water inlet 111 is shielded by the water baffle 2, so that water with different depths enters different sampling chambers 11 through different water inlets 111 to sample water with different depths. Then, the water stop 1121 is released from blocking the water outlet 112, and the taken water sample is poured into a sampling bottle.

Combine fig. 2 and fig. 4, breakwater 2 is located the inside of sampling chamber 11, and breakwater 2 is close to the sealed pad 23 of the one side fixedly connected with rubber material of water inlet 111, and sealed pad 23 is with the inner wall butt of sampling chamber 11 to shelter from water inlet 111. The water baffle 2 is provided with guide rods 22, each water baffle 2 is provided with two guide rods 22, and the two guide rods 22 are uniformly distributed along the length direction of the water baffle 2 at intervals. The guide rod 22 is vertically arranged, the guide rod 22 vertically penetrates through the water baffle 2 and then is in sliding connection with the water baffle 2, and two ends of the guide rod 22 are fixedly connected with the partition plate 13.

Referring to fig. 2 and 3, a connecting rod 21 for integrally connecting the plurality of water deflectors 2 is connected between the plurality of water deflectors 2. The connecting rod 21 is vertically positioned inside the sampling rod 1, and the peripheral surface of the connecting rod 21 is fixedly connected with one side of the water baffle 2 far away from the water inlet 111. The bottom of connecting rod 21 and the bottom butt of thief rod 1, the top of connecting rod 21 pass three baffle 13 in proper order and with baffle 13 sliding connection, then the top and the thief rod 1 sliding connection of thief rod 1 are worn out to the top of connecting rod 21. A lifting handle 211 for lifting the connection rod 21 is fixedly connected to the top end of the connection rod 21. A pressing component 3 for pressing the connecting rod 21 is connected between the top end of the connecting rod 21 and the top end of the sampling rod 1.

After putting into the aquatic with the vertical sample thief rod 1, handheld lift handle 211 upwards mentions connecting rod 21, makes breakwater 2 upwards slide along guide bar 22 simultaneously to relieve breakwater 2 and to the sheltering from of water inlet 111, make the water of the different degree of depth get into different sample rooms 11 from different water inlets 111, then, push down connecting rod 21, breakwater 2 shelters from water inlet 111 the back, takes out sample thief rod 1. Because connecting rod 21 and breakwater 2 all are located the inside of thief rod 1, then when removing connecting rod 21 and breakwater 2, can not produce the disturbance to the outside aquatic of thief rod 1, can improve the accuracy of the water that gets into sampling chamber 11 to improve the degree of accuracy that the water detected.

As shown in fig. 3, the pressing assembly 3 includes a lower pressing plate 31, an upper pressing plate 32, a support rod 33 and an elastic member, the lower pressing plate 31 is horizontally disposed, and the top end of the connecting rod 21 penetrates through the lower pressing plate 31 and then is fixedly connected to the lower pressing plate 31. When the bottom end of the connecting rod 21 abuts against the bottom surface of the sampling rod 1, the lower platen 31 abuts against the top surface of the sampling rod 1. The support rods 33 are vertically provided in two and are symmetrically disposed about the center line of the connecting rod 21. The bottom end of the support rod 33 is fixedly connected with the top surface of the sampling rod 1. Two upper pressing plates 32 are horizontally arranged and are respectively connected with two supporting rods 33. One end of the upper pressing plate 32 is fixedly connected with the top end of the supporting rod 33, and the other end is connected with the elastic piece. The elastic member is a compression spring 34, and the compression spring 34 extends and contracts in a vertical direction and is in a compressed state. The top end of the compression spring 34 is fixedly connected with the bottom surface of the upper press plate 32. The bottom end of the compression spring 34 is fixedly connected with the lower pressing plate 31.

The compression spring 34 is in a compressed state, and applies downward pressure to the lower pressure plate 31, so that the lower pressure plate 31 abuts against the top surface of the sampling rod 1, and the bottom end of the connection rod 21 abuts against the bottom end of the sampling rod 1. At this time, the water inlet 111 is shielded by the water baffle 2, preventing water from entering the sampling chamber 11.

When the water inlet 111 is required to be shielded by the water baffle 2, the connecting rod 21 is lifted upwards by the handheld lifting handle 211, the compression spring 34 is further compressed, and the water baffle 2 moves upwards along the guide rod 22 to shield the water inlet 111, so that water enters the sampling chamber 11. Then, the lifting handle 211 is released, the connecting rod 21 moves downwards under the action of the elastic force of the compression spring 34, so that the water baffle 2 shields the water inlet 111, manual downward pressing on the connecting rod 21 is not needed, and the labor intensity of operators is reduced.

The utility model discloses a use as follows:

during the sample, with the vertical water of putting into of thief rod 1, treat that the water is stable after, handheld lifting handle 211 is to mentioning connecting rod 21, and at this moment, compression spring 34 is further compressed, and breakwater 2 removes sheltering from to water inlet 111 along guide bar 22 rebound. The water with the depth corresponding to each water inlet 111 enters the sampling chamber 11 through the corresponding water inlet 111, and the operation of sampling the water with different depths is completed. Then, the connecting rod 21 is released, the connecting rod 21 is restored to the original position by the elastic force of the compression spring 34, and at the same time, the water guard 2 shields the water inlet 111. After the sampling rod 1 is taken out, the water stop 1121 is removed from the water outlet 112, and the water in the sampling chamber 11 is poured into a sampling bottle. Because the breakwater 2 is located the inboard of sampling chamber 11, when removing breakwater 2, can not produce the disturbance to the water of water inlet 111 department, reduce the water of the different degree of depth and mix the condition together, improve the accuracy of sample to improve the accuracy of water body measurement.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
