Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.Wherein the arrow in figure middle cylinder body indicates the direction of current while representing sampling.
As shown in Fig. 3 to Fig. 9, the Sewage Sampler providing of the present utility model, comprise cylindrical shell 1, the top of cylindrical shell 1 is provided with the water inlet 12 to lower recess, Sewage Sampler is also provided with the seal assembly 2 for matching with water inlet 12, seal assembly 2 comprise be positioned at water inlet 12 tops for spacing locating part 23, be slidably matched for being sealed into the gland bonnet 21 at the mouth of a river 12 and through water inlet 12 and the connecting rod 22 that can slide up and down along water inlet 12 with water inlet 12, the top of connecting rod 22 is connected with locating part 23, and the bottom of connecting rod 22 is connected with gland bonnet 21.Gland bonnet 21 is slidably matched and refers to water inlet 12: drive lower sealing cover 21 down slidings at connecting rod 22 are separated with water inlet 12, so that water sample enters cylindrical shell 1 from water inlet 12, or upward sliding contacts with water inlet 12, by water inlet 12 sealings, to keep inner barrel to be isolated from the outside.Be specially: when connecting rod 22 glides along water inlet 12, gland bonnet 21 is separated with water inlet 12 under the drive of pull bar 22, and water sample enters in cylindrical shell 1; When connecting rod 22 is under external force when sliding in import 12, gland bonnet 21 upward slidings, and contact with water inlet 12, to be sealed into the mouth of a river 12, make water sample and external isolation in cylindrical shell 1.During concrete sampling, Sewage Sampler is placed in water body to be sampled, decontrols seal assembly 2, seal assembly 2 relies on the gravity of self to decline, and gland bonnet 21 is separated with water inlet 12, and water sample enters in cylindrical shell 1.After having sampled, will on seal assembly 2, carry, make the gland bonnet 21 of seal assembly 2 be connected with water inlet 12 and by water inlet 12 sealings, carry seal assembly 2 in continuation, seal assembly 2 drives cylindrical shell 1 to rise.In the process that Sewage Sampler is proposed from water body to be sampled, outside is applied to the gravity that the power that draws high making progress on seal assembly 2 must be greater than the Sewage Sampler of filling water sample, therefore the acting force making progress at 21 pairs of water inlet 12 positions of gland bonnet is greater than the total force of cylindrical shell 1 and cylindrical shell 1 interior water sample, thereby guarantee that gland bonnet 21 rises afterwards and leaves in the process of sampling water body in sampling, remain the sealing with water inlet 12, water sample and outside in cylindrical shell 1 are isolated completely, thereby guarantee the accuracy of sampling.
As shown in Figure 3 and Figure 6, above-mentioned seal assembly 2 also comprises the pressurization part 24 being connected on locating part 23.Pressurization part 24 can increase the gravity of seal assembly 2, makes Sewage Sampler of the present utility model in sampling, and seal assembly 2 can be separated with water inlet 12 smoothly, the smoothness of water inlet while guaranteeing sampling.
In a kind of implementation column of the present utility model, cylindrical shell 1 is provided with for drawing high the cylindrical shell stay cord 11 of cylindrical shell 1, and one end of cylindrical shell stay cord 11 is connected with the top of described cylindrical shell 1, and the other end is connected to cylindrical shell stay cord draw ring 3.Cylindrical shell stay cord 11, for controlling the stability of cylindrical shell 1, loosens cylindrical shell stay cord 11 cylindrical shell 1 is placed in water body to be sampled, and guarantees cylindrical shell 1 run-off the straight in sampling.Cylindrical shell stay cord draw ring 3 is set, is convenient to operator's practical operation.
In a kind of implementation column of the present utility model, seal assembly 2 is provided with for drawing high the seal assembly stay cord 25 of seal assembly 2, and one end of seal assembly stay cord is connected with the top of seal assembly 2, and the other end is connected with seal assembly stay cord draw ring 4.Seal assembly stay cord 25 is for controlling the lifting of seal assembly 2, thus the switching of the water inlet 12 of control cylindrical shell 1.Draw high the rising that seal assembly stay cord 25 can drive cylindrical shell 1, the most whole Sewage Sampler is pulled out water body to be sampled simultaneously.Seal assembly stay cord draw ring 4 is set, is convenient to operator's practical operation.
In a kind of implementation column of the present utility model, as shown in Figure 3 and Figure 9, the bottom of above-mentioned cylindrical shell 1 is provided with water delivering orifice 13 and water delivering orifice gland bonnet 14, and water delivering orifice gland bonnet 14 is removably connected on water delivering orifice 13.On cylindrical shell 1, set out the mouth of a river 13, facilitate the outflow of the water sample in cylindrical shell 1.Sewage Sampler of the present utility model is when sampling, and water delivering orifice gland bonnet 14 is by water delivering orifice 13 sealings, the water sample in assurance cylindrical shell 1 and extraneous isolation.When cylindrical shell 1 leaves after the water body sampling, open water delivering orifice gland bonnet 14, the water sample in cylindrical shell 1 flows out from water delivering orifice 13, facilitates next step analysis to water sample.Water delivering orifice gland bonnet 14 can adopt spiral fit system to link together with water delivering orifice 13, is convenient to dismounting between the two.
The bottom of above-mentioned cylindrical shell 1 is also provided with leg 15.In cylindrical shell 1 bottom, be provided with leg 15, facilitate the placement of cylindrical shell 1.Improved the stability of Sewage Sampler.
Fig. 7-Fig. 9 be Sewage Sampler of the present utility model at the schematic diagram of sampling process, the direction of current when wherein the arrow in figure middle cylinder body 1 indicate to represent sampling.The concrete operation of using Sewage Sampler of the present utility model to sample is as follows:
First, Sewage Sampler is placed in water body to be sampled, tension cylindrical shell stay cord 11, loosens seal assembly stay cord 25, and seal assembly 2 is separated with the water inlet 12 of cylindrical shell 1, and water sample flows in cylindrical shell 1.
Then, after the in-built full water sample of cylindrical shell 1, tension seal assembly stay cord 25, make seal assembly 2 increase, and the gland bonnet 21 of seal assembly 2 is connected and seals with water inlet 12.Loosen cylindrical shell stay cord 11, upwards draw high seal assembly stay cord 25, make seal assembly 2 increase, seal assembly 2 drives cylindrical shell 1 to rise simultaneously, has guaranteed the sealing integrity of 2 pairs of cylindrical shells 1 of seal assembly.
Finally, cylindrical shell 1 is pulled out water body to be sampled, and opens water delivering orifice gland bonnet 14, and the water sample in cylindrical shell 1 is discharged from water delivering orifice 13, and then the water sample gathering is analyzed.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
