[0030] 31 first guide rope, 32 cable; DETAILED DESCRIPTION
[0031] In order to make the technical solutions and advantages of the present application more clearly understood, the exemplary embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive enumeration of all embodiments. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0032] The present application will be further described below with reference to the drawings.
[0033] As Figures 1 to 3 shown, the depth-keeping water sampling device for ponds 100 according to the present application mainly comprises a float 11 and a sampling mechanism arranged below the float 11. Preferably, the sampling mechanism can be used to collect pond culture water as a detection sample, and the sampling mechanism comprises a sampler 21 configured in the form of a sleeve, a weighter 22 arranged below the sampler 21, and a support rod 23 arranged between the sampler 21 and the weighter 22.
[0034] Preferably, a storage chamber in the form of a column is formed inside the sampler 21 for accommodating the pond water sample; since the plurality of support rods 23 are arranged at a circumferential interval, a guide channel 24 will be formed between adjacent support rods 23, and from this, during the sinking of the sampling mechanism, the pond water sample will be introduced into the storage chamber under the action of the guide channel 24, so as to facilitate subsequent collection and research analysis work.
[0035] In the present application, the pond water sample enters from three different positions of the guide channel 24, in other words, the device can simultaneously obtain water samples of different directions at the same depth, so that representative pond water samples can be obtained, and therefore the experimental data ultimately obtained has stronger authority and authenticity.
[0036] In one embodiment, the sampling mechanism further comprises a pair of valve mechanisms. Preferably, the two valve mechanisms are respectively installed at two ends of the sampler 21, whereby during the sinking of the sampler 21, the valve mechanisms are opened under the action of water pressure to allow the pond water sample to enter, and as the sampler 21 continues to sink, the pond water sample that enters the storage chamber first is squeezed out by the pond water sample that enters later until the sampler 21 reaches the predetermined position and no longer sinks.
[0037] In one embodiment of the present application, as shown in Figure 3 each valve mechanism comprises a transversely arranged valve rod 25 and a pair of symmetrically arranged valve covers 26. Preferably, the valve cover 26 is configured as a semicircular structure, and the ends of the two valve covers 26 are hinged to the valve rod 25. From this, when the sampler 21 sinks, the valve cover 26 can be smoothly flipped up under the action of water pressure to allow the pond water sample to enter the storage chamber through the guide channel 24.
[0038] In one embodiment of the present application, a limiting step (not shown) extending radially inward and used for abutting against the valve cover 26 is arranged at both ends of the storage chamber. Preferably, when the sampler 21 reaches the predetermined position and is lifted after being filled with the pond water sample, the valve cover 26 will be flipped down under the action of water pressure and gravity until it abuts against the limiting step, from which the pond water sample in the storage chamber will be completely closed, and at this time the pond water sample is the water sample of the required depth collected this time.
[0039] In one embodiment of the present application, the weighter 22 is configured as a cylindrical structure, and a containing chamber for placing the weight counterweight (not shown) is formed in the inside of the weighter 22. Preferably, by increasing or decreasing the number of weight counterweights, the overall weight of the weighter 22 and the sampler 21 can be adjusted, so as to ensure that the sampler 21 can smoothly sink to the target position.
[0040] Preferably, after the sampler 21 sinks to the target position, it needs to be stationary for 2-3 minutes before the lifting operation is performed.
[0041] Preferably, the buoyancy of the float 11 is greater than the total weight of the sampler 21 and the weighter 22. Therefore, by adjusting the position of the float 11 on the first guide rope 31 (introduced below), it can be ensured that the sampler 21 can smoothly sink to the target position, so as to accurately collect the pond water sample at the target depth.
[0042] In one embodiment, as shown in Figures 1 to 2As shown, the water sampling device with depth setting for pond 100 further comprises a first leading rope 31 connected with the float 11. Preferably, the first leading rope 31 is configured as a linear structure, and a plurality of spaced-apart line holes (not shown) are arranged along the length direction of the first leading rope 31. Preferably, the adjacent line holes are equidistantly arranged, so as to more easily determine the sinking depth of the sampler 21.
[0043] Preferably, as Figure 2 As shown, the water sampling device with depth setting for pond 100 further comprises a position limiter 12. Preferably, the position limiter 12 can extend through the line hole and be fixed on the float 11, so as to determine the position of the float 11 on the first leading rope 31.
[0044] However, in other embodiments, other limiting methods can also be adopted, i.e. the float 11 can be fixed at a specific position on the first leading rope 31.
[0045] In one embodiment, as Figure 1 As shown, the water sampling device with depth setting for pond 100 further comprises a second leading rope arranged between the first leading rope 31 and the sampler 21. In the present application, the second leading rope is converged by at least three cable lines 32, and a plurality of hooks are arranged on the bottom end side wall of the sampler 21, so that each cable line 32 is fixedly connected with a hook, so as to ensure that the sampler 21 can stably sink in the pond.
[0046] In the present application, as Figure 1 As shown, the second leading rope is converged by four cable lines 32.
[0047] Compared with the prior art, the present application has the following advantages:
[0048] Firstly, the present application can first select the target water level depth, and complete the task of depth setting sampling by adjusting the position of the float 11 on the first leading rope 31, i.e. ensuring that the sampler 21 can smoothly sink to the target position, so as to more easily collect the pond water sample belonging to the specific position.
[0049] Secondly, the present device can accurately collect pond water samples at different levels (depths), so as to minimize the deviation of water quality detection parameters.
