Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, and particularly relates to an intelligent water quality detection device for a pond. Background Technique

[0002] Currently, for water quality detection instruments, when measuring water quality parameters (such as ammonia nitrogen, pH value, etc.), it is generally necessary to place the water sample in a test bottle, manually add the corresponding reagent and mix it, and then place the mixed solution in the detection instrument for detection. However, this process is cumbersome and requires manual operation, including steps such as loading the water sample, adding the reagent, and mixing, which increases the operation complexity and time cost. Content of the Utility Model

[0003] Aiming at the technical problems existing in the prior art, the utility model provides an intelligent water quality detection device for a pond to solve the problem of cumbersome steps in the existing water quality detection.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: An intelligent water quality detection device for a pond, comprising:

[0005] A water quality tester;

[0006] A test bottle, which is arranged in the test area of the water quality tester;

[0007] A syringe, which comprises a syringe barrel, a first injection tube, a second injection tube and a third injection tube. The syringe barrel is located on one side of the water quality detector, and the first injection tube, the second injection tube and the third injection tube are respectively fixed on the output end of the syringe barrel;

[0008] A control valve assembly, which comprises a first valve, a second valve and a third valve. The first valve is arranged on the first injection tube, the second valve is arranged on the second injection tube, and the third valve is arranged on the third injection tube;

[0009] A water suction pipe, one end of which is fixed on the first injection tube;

[0010] An introduction pipe, which is arranged between the test bottle and the second injection tube;

[0011] A reagent suction pipe, one end of which is fixed on the third injection tube.

[0012] The beneficial effects of the utility model are:

[0013] 1) The detection device is equipped with three injection tubes at the output end of the syringe, namely injection tube one, injection tube two, and injection tube three, and is controlled by valve one, valve two, and valve three. When valve two is closed and valve one and valve three are opened respectively, the syringe uses negative pressure to extract the water liquid and reagent, and mixes them in the syringe barrel. Subsequently, through positive pressure output, the mixed liquid is injected into the test bottle through injection tube two. Repeated operations can make the mixed liquid mix more fully and improve the detection accuracy. Therefore, this solution simplifies the operation steps, realizes the synchronous sampling and mixing of the reagent and the water liquid, thereby improving the detection efficiency and accuracy.

[0014] Based on the above technical solution, the present utility model can be further improved as follows.

[0015] Further, the syringe further includes a piston and a push rod. The piston is disposed inside the syringe barrel, and one end of the push rod is fixed to one side of the piston.

[0016] The beneficial effect of adopting the above further solution is that when negative pressure extraction operation is required, by controlling the movement of the push rod, negative pressure can be generated inside the syringe barrel, so that the liquid is extracted into the syringe. Conversely, when positive pressure output is required, the push rod can also be controlled to make the piston apply pressure to the inside of the syringe barrel, pushing the liquid to flow towards the output end of the syringe.

[0017] Further, a fixing bracket for limiting the syringe barrel is provided on one side of the water quality tester.

[0018] Further, the fixing bracket is an annular tube made of elastic material, and one side of the fixing bracket has an opening.

[0019] Further, the radial dimension of the fixing bracket is larger than the radial dimension of the syringe barrel, and the width dimension of the opening is smaller than the radial dimension of the syringe barrel.

[0020] The beneficial effect of adopting the above further solution is that the fixing bracket is an annular tube made of elastic material and has an opening on one side, allowing the syringe barrel to be inserted into the annular tube from the opening. The characteristic of the elastic material enables the opening area to deform, thus expanding the opening to facilitate the syringe barrel to enter the annular tube. When the syringe barrel enters the annular tube, the opening area of the annular tube returns to its original state. Since the opening width is smaller than the radial dimension of the syringe barrel, the syringe barrel is effectively limited, preventing it from falling off or shifting.

[0021] Further, scales are provided on the outer side of the syringe barrel.

[0022] The beneficial effect of adopting the above further solution is that the design of providing scales on the outer side of the syringe barrel enables users to more accurately control and adjust the injection volume, which is particularly useful for situations where specific reagents or samples need to be accurately added during water quality testing.

Detailed Embodiments

[0027] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0028] The design of providing scales on the outer side of the barrel enables users to more accurately control and adjust the injection volume, which is particularly useful in cases where specific reagents or samples need to be accurately added during water quality testing. For this reason, the inventor of this utility model proposed an intelligent water quality detection device for ponds to solve the above problems.

[0029] The present utility model provides the following preferred embodiments

[0030] As Figure 1 and Figure 2 shown, an intelligent water quality detection device for ponds includes:

[0031] Water quality tester 10;

[0032] Test bottle 20, and the test bottle 20 is arranged in the test area of the water quality tester 10 (adopting the ERUN - SP - 808 type portable water quality detector for fish ponds and aquaculture);

[0033] Syringe 30, the syringe 30 includes a barrel 301, an injection tube 1 304, an injection tube 2 305 and an injection tube 3 306. The barrel 301 is located on one side of the water quality detector, and the injection tube 1 304, the injection tube 2 305 and the injection tube 3 306 are respectively fixed on the output end of the barrel 301;

[0034] Control valve assembly 40, the control valve assembly 40 includes valve one 401, valve two 402 and valve three 403. Valve one 401 is arranged on injection tube one 304, valve two 402 is arranged on injection tube two 305, and valve three 403 is arranged on injection tube three 306;

[0035] Water suction pipe 50, one end of the water suction pipe 50 is fixed on injection tube one 304;

[0036] Introduction pipe 60, the introduction pipe 60 is arranged between the test bottle 20 and injection tube two 305;

[0037] Reagent suction tube 70, one end of the reagent suction tube 70 is fixed on injection tube three 306;

[0038] By arranging three injection tubes at the output end of the syringe 30, namely injection tube one 304, injection tube two 305 and injection tube three 306, and controlling them by means of valve one 401, valve two 402 and valve three 403. When valve two 402 is closed and valve one 401 and valve three 403 are respectively opened, the water liquid and reagent are sucked by the negative pressure of the syringe 30 and mixed in the syringe barrel 301. Subsequently, through positive pressure output, the mixed liquid is injected into the test bottle 20 through injection tube two 305. Repeated operations can make the mixed liquid mix more fully and improve the detection accuracy. Therefore, this solution simplifies the operation steps, realizes the synchronous sampling and mixing of the reagent and water liquid, thereby improving the detection efficiency and accuracy.

[0039] In this embodiment, as Figure 1 and Figure 2 shown, the syringe 30 further includes a piston 302 and a push rod 303. The piston 302 is arranged in the syringe barrel 301. One end of the push rod 303 is fixed on one side of the piston 302. When negative pressure suction operation is required, by controlling the movement of the push rod 303, negative pressure can be generated in the syringe barrel 301, so that the liquid is sucked into the syringe 30. On the contrary, when positive pressure output is required, the push rod 303 can also be controlled to make the piston 302 apply pressure to the inside of the syringe barrel 301, pushing the liquid to flow towards the output end of the syringe 30.

[0040] In this embodiment, as Figure 1 and Figure 2 shown, on one side of the water quality tester 10, there is a fixing frame 80 for limiting the syringe barrel 301. The fixing frame 80 is an annular tube made of elastic material, and one side of the fixing frame 80 has an opening 801. The radial dimension of the fixing frame 80 is larger than the radial dimension of the syringe barrel 301, and the width dimension of the opening 801 is smaller than the radial dimension of the syringe barrel 301;

[0041] The fixing bracket 80 is made of an annular tube of elastic material, which has an opening 801 on one side. The opening 801 allows the syringe barrel 301 to be inserted into the annular tube. The characteristic of the elastic material enables the opening 801 area to deform, thus expanding the opening 801 to facilitate the entry of the syringe barrel 301 into the annular tube. When the syringe barrel 301 enters the annular tube, the opening 801 area of the annular tube returns to its original state. Since the width of the opening 801 is smaller than the radial dimension of the syringe barrel 301, the syringe barrel 301 is effectively limited in position, preventing it from falling off or shifting.

[0042] In this embodiment, as Figure 1 and Figure 2 shown, a scale 90 (the scale 90 is in volume units) is provided on the outer side of the syringe barrel 301. The design of providing the scale 90 on the outer side of the syringe barrel 301 enables the user to more accurately control and adjust the injection volume, which is particularly useful for situations where specific reagents or samples need to be accurately added in water quality testing.

[0043] The specific working process of the present utility model is as follows:

[0044] (1) First, draw out the water quality sample to be detected

[0045] First, close the valve two 402 and the valve three 403, open the valve one 401, and immerse the water suction pipe 50 into the water quality sample to be detected. At this moment, by controlling the movement of the push rod 303, a negative pressure can be generated in the syringe barrel 301, so that the liquid to be measured passes through the water suction pipe 50 and the injection pipe one 304 and is drawn into the syringe barrel 301. By observing the volume scale 90 on the outer side of the syringe barrel 301, the volume value of the liquid to be measured drawn can be clearly known in real time. After a certain volume of the liquid to be measured is drawn;

[0046] At the same time, then open the valve three 403 and close the valve one 401, while the state of the valve two 402 remains unchanged. Insert the reagent suction pipe 70 into the reagent bottle, and again control the movement of the push rod 303 to generate a negative pressure in the syringe barrel 301, so that the reagent passes through the reagent suction pipe 70 and the injection pipe three 306 and is drawn into the syringe barrel 301 to be mixed with the liquid to be measured;

[0047] Finally, open the valve two 402, close the valve one 401 and the valve three 403, and through positive pressure output, the mixed liquid in the syringe barrel 301 is injected into the test bottle 20 through the injection pipe two 305 and the introduction pipe 60. In addition, by repeatedly sucking the mixed liquid in the test bottle 20 into the syringe barrel 301 with the syringe 30 and then injecting the mixed liquid in the syringe barrel 301 into the test strip again, the mixed liquid can be mixed more evenly.

[0048] (2) First, draw the reagent

[0049] First, open valve three 403, close valve one 401 and valve two 402, insert the reagent suction tube 70 into the reagent bottle, control the movement of the push rod 303 to generate negative pressure in the syringe barrel 301, and draw a certain volume of reagent into the syringe barrel 301 through the reagent suction tube 70 and the third injection tube 306;

[0050] Meanwhile, close valve two 402 and valve three 403, open valve one 401, and immerse the water suction tube 50 into the water quality sample to be tested. At this moment, by controlling the movement of the push rod 303, negative pressure can be generated in the syringe barrel 301, so that the liquid to be tested is drawn into the syringe 30 through the water suction tube 50 and the first injection tube 304 and mixed with the reagent in the syringe barrel 301;

[0051] Finally, open valve two 402, close valve one 401 and valve three 403, and inject the mixed liquid in the syringe barrel 301 into the test bottle 20 through the second injection tube 305 and the introduction tube 60 by positive pressure output. In addition, use the syringe 30 to repeatedly draw the mixed liquid in the test bottle 20 into the syringe barrel 301 and then inject the mixed liquid in the syringe barrel 301 back into the test piece, which can make the mixed liquid more evenly mixed.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
