Description

Technical Field

[0001] The utility model relates to the field of water quality sampling devices, in particular to a water quality sampling and detecting device for fish and shrimp farming. Background Art

[0002] In the field of fish and shrimp farming, it is necessary to detect the water quality of the water body to ensure the water quality in the fish and shrimp farming pond. In the prior art, the device for sampling water quality usually samples by pumping out the water in the fish and shrimp farming pond with a water pump. For example, a water quality sampler disclosed in the patent application No. 202121272150.X. In this water quality sampler, both the water pump and the water sample collection box are fixed on the mounting plate. Inevitably, when operating, the mounting plate needs to be placed on the fish and shrimp farming pond. After the water sample is pumped out, the mounting plate is fished out. This operation process requires reaching into the water and getting the hands wet. Therefore, the hands need to be wiped or washed afterwards, which is rather inconvenient. Summary of the Utility Model

[0003] Aiming at the deficiencies proposed in the above background art, the utility model provides a water quality sampling and detecting device for fish and shrimp farming.

[0004] The utility model adopts the following technical scheme:

[0005] A water quality sampling and detecting device for fish and shrimp farming, the device comprising:

[0006] A box body, one side inside the box body is connected with a drain pipe, the drain pipe extends out of the box body, and one end of the drain pipe inside the box body bends upward to be vertical;

[0007] A partition board, a threaded sleeve is arranged on the bottom surface of the partition board, the threaded sleeve fixes a first connecting pipe and a second connecting pipe, and one ends of the first connecting pipe and the second connecting pipe far away from the threaded sleeve both bend downward to be vertical;

[0008] A collection bottle, the collection bottle is connected to the threaded sleeve, so that the collection bottle is communicated with the first connecting pipe and the second connecting pipe;

[0009] A water pump, the water pump is fixed inside the box body, and the water inlet pipe connected to the water inlet end of the water pump extends downward to expose outside the bottom surface of the box body;

[0010] Wherein, after the partition board is placed inside the box body, one end of the first connecting pipe that bends downward is connected to the drainage end of the water pump to be communicated, and one end of the second connecting pipe that bends downward is connected to the end of the drain pipe to be communicated.

[0011] In a possible implementation, the device further includes a liquid level sensor and a control unit. Both the liquid level sensor and the control unit are fixed inside the box body, and after the control unit receives the signal that the liquid level sensor is triggered, it controls the opening and closing of the water pump. The bottom surface of the box body is recessed inward from the outside to form a recess groove, and the sensing end of the liquid level sensor passes through the side wall of the recess groove into the recess groove.

[0012] In a possible implementation, one end of the drain pipe that bends upward is fixedly connected with a sleeve, and a sealing ring is embedded in the bottom surface of the sleeve. After the partition plate is placed inside the box body and on the receiving platform, one end of the second connecting pipe that bends downward is embedded into the sleeve and presses against the sealing ring.

[0013] In a possible implementation, a sealing ring is embedded in the port of the drainage end of the water pump. After the partition plate is placed inside the box body and on the receiving platform, one end of the first connecting pipe that bends downward is embedded into the drainage end of the water pump and presses against the sealing ring.

[0014] In a possible implementation, the side of the box body near the open part is inclined outward, and the side of the partition plate is bent to form a flanging with an opening downward, so that the flanging can swing elastically towards the middle of the partition plate. After the partition plate is placed inside the box body, the flanging presses downward against the inclined side of the box body and swings inward.

[0015] In a possible implementation, a box cover is hinged on the box body. One end of the box cover far from the hinge with the box body is fixedly connected to the box body through a buckle. After the box cover covers the box body and is fixed to the box body, the box cover presses down the partition plate, so that the flanging presses downward against the inclined side of the box body and swings inward.

[0016] From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: When collecting water samples using the present invention, only need to press the box body down so that a part of the bottom is below the water level of the aquaculture pond, make the water inlet pipe enter the aquaculture pond, and then control the water pump to pump water, then the water in the aquaculture pond can be pumped upward through the water inlet pipe and enter the collection bottle through the first connecting pipe. When it is observed that water is discharged from the drain pipe, it means that the collection bottle is already full of water samples. At this time, turn off the water pump and lift the box body upward. Thus, the water quality sampling is completed. This collection process only needs to grasp the upper part of the box body and does not need to reach into the water to fish out the box body, so the hands will not be wet, and it is therefore more convenient.

[0028] The present utility model provides a water quality sampling and detection device for fish and shrimp farming. As shown in Figure 1 and 2 the figure, the device includes a box body 11, a partition board 2, a collection bottle 3, a water pump 4, and a control unit. Among them, the control unit and the water pump 4 are both fixedly installed inside the box body 11, and a storage battery can also be configured inside the box body 11 to supply power to each electrical appliance. Further, the control unit can be a single-chip microcomputer processor, and an operation panel can also be configured outside the box body 11. By triggering the operation panel to issue an instruction for the water pump 4 to work, the control unit directly controls the opening and closing of the water pump 4 according to this instruction.

[0029] As shown in the attached Figure 2 and 5 figure, a threaded sleeve 21 is provided on the bottom surface of the partition plate 2, and the mouth of the collection bottle 3 is screwed into the threaded sleeve 21. Referring to the attached Figure 3 figure again, the side 111 of the box body 11 near the open part is inclined outward, so that the open part of the box body 11 forms an open mouth with a tapered outward expansion. The side of the partition plate 2 is bent 180° to form a flanging 24 with the opening facing downward. This structure enables the flanging 24 to elastically swing towards the middle of the partition plate 2 (i.e., the left side of the attached Figure 3 figure). After the partition plate 2 is placed in the box body 11 and pressed down, the flanging 24 can be pressed downward against the inclined side of the box body 11 and swing towards the middle of the partition plate 2, thereby clamping the partition plate 2 at a position near the upper part in the box body 11 and making the collection bottle 3 located in the box body 11.

[0030] As shown in the attached Figure 5 figure, the threaded sleeve 21 fixes the first connecting pipe 22 and the second connecting pipe 23. The fixing method can be adhesive fixing, and one end of the first connecting pipe 22 and one end of the second connecting pipe 23 both penetrate into the upper part inside the threaded sleeve 21. The ends of the first connecting pipe 22 and the second connecting pipe 23 away from the threaded sleeve 21 are both bent downward to be vertical. After the collection bottle 3 is screwed onto the threaded sleeve 21, the mouth of the collection bottle 3 can be fixed inside the threaded sleeve 21, so that the collection bottle 3 is communicated with the first connecting pipe 22 and the second connecting pipe 23.

[0031] Referring to the attached Figure 2 figure again, the water inlet end of the water pump 4 is connected to the water inlet pipe 12, and the water inlet pipe 12 extends downward to expose outside the bottom surface of the box body 11. Preferably, the part of the water inlet pipe 12 exposed outside the box body 11 can be connected with a filter head to filter impurities such as waterweeds. Referring to the attached Figure 6 and 7 figure again, a sealing ring is embedded in the port of the drainage end 401 of the water pump 4. After the partition plate 2 is placed in the box body 11, the downwardly bent end of the first connecting pipe 22 is correspondingly embedded into the drainage end 401 of the water pump 4 and pressed against the sealing ring, thereby realizing the automatic communication between the downwardly bent end of the first connecting pipe 22 and the drainage end 401 of the water pump 4, and the sealing ring can seal the gap between the end of the first connecting pipe 22 and the drainage end 401 of the water pump 4. Referring to the attached Figure 8, on one side inside the box body 11, a drain pipe 13 is also connected. The drain pipe 13 extends outside the box body 11, and one end of the drain pipe 13 inside the box body 11 bends upward to be vertical. A connecting sleeve 131 is fixedly connected to the upward-bent end of the drain pipe 13. A sealing ring is also embedded in the bottom surface inside the connecting sleeve. After the partition plate 2 is placed inside the box body 11, the downward-bent end of the second connecting pipe 23 correspondingly inserts into the connecting sleeve and presses against the sealing ring, thereby realizing the connection between the downward-bent end of the second connecting pipe 23 and the end of the drain pipe 13, and the sealing ring can seal the gap between the end of the second connecting pipe 23 and the drain pipe 13. It can be seen that when the partition plate 2 is placed inside the box body 11 and pressed down, the downward-bent end of the first connecting pipe 22 can be connected to the drainage end 401 of the water pump 4 to be connected, and the downward-bent end of the second connecting pipe 23 can be connected to the end of the drain pipe 13 to be connected, so as to realize that both the water outlet pipe and the drain pipe 13 are connected to the collection bottle 3.

[0032] In reference to the attached Figure 1 and 4 , a box cover 14 is hinged on the box body 11, and the above operation panel can be arranged on the box cover 14. The end of the box cover 14 far from the hinge with the box body 11 is fixedly connected to the box body 11 through a buckle 15. Specifically, the buckle 15 can be a fastener used in existing technology for luggage, which includes a male buckle 151 and a female buckle 152. Among them, the female buckle 152 is fixed on the box cover 14, and the male buckle 151 is fixed on the box body 11. After the box cover 14 is turned downward to cover the box body 11, fixing the male buckle 151 and the female buckle 152 can fix the box cover 14 on the box body 11. And after the box cover 14 is turned downward, the partition plate 2 can be further pressed down, so that the end of the first connecting pipe 22 is tightly pressed inside the drainage end 401 of the water pump 4, and the end of the second connecting pipe 23 is tightly pressed inside the connecting sleeve 131, making the sealed connection between the first connecting pipe 22 and the water pump 4 and the sealed connection between the second connecting pipe 23 and the drain pipe 13 both tighter.

[0033] During use, place the box body 11 downward on the aquaculture pond and press the box body 11 downward so that a part of the bottom is below the water level of the aquaculture pond, and make the water inlet pipe 12 enter the aquaculture pond; then control the water pump 4 to start pumping water, and the water in the aquaculture pond can be pumped upward through the water inlet pipe 12 and enter the collection bottle 3 through the first connecting pipe 22. When the water in the collection bottle 3 overflows, it overflows from the second connecting pipe 23 and then is discharged out of the box body 11 through the discharge pipe. When it is observed that there is water discharged from the drain pipe 13, the water pump 4 can be turned off and the box body 11 can be lifted upward. Thus, the water quality sampling is completed. After lifting the box body 11, open the box cover 14, pick up the partition plate 2, and screw out the collection bottle 3 to obtain the collected water sample.

[0034] Preferably, a first handle 25 is provided on the box cover 14 to facilitate gripping the box body 11. A second handle 25 is provided on the partition 2, and the partition 2 can be conveniently picked up from the box body 11 by holding the second handle 25, and after the box cover 14 is turned down and fixed to the box body 11, the box cover 14 can be pressed against the second handle 25 to further press the partition 2 as a whole into the box body 11.

[0035] Please refer to the attached Figure 2 As shown, the utility model further includes a liquid level sensor 5, which is fixed in the box body 11. Specifically, the bottom surface of the box body 11 is recessed from outside to inside to form a clearance groove 101, and the sensing end 51 of the liquid level sensor 5 passes through the side wall of the clearance groove 101 to the inside of the clearance groove 101, and the control unit controls the start and stop of the water pump 4 after receiving the signal that the liquid level sensor 5 is triggered. Preferably, the liquid level sensor 5 in this embodiment can be a float liquid level sensor 5, and the sensing end 51 of the liquid level sensor 5 is a float, that is, the float is located in the clearance groove 101. After adopting this structure, when sampling the water quality of the breeding pond, the box 11 is placed downward on the breeding pond and the box 11 is pressed down until the bottom part is below the water level of the breeding pond, so that the water can contact the liquid level sensor 5 to drive the float to swing upward, thereby triggering the liquid level sensor 5, so that the control unit controls the water pump 4 to start after receiving the signal, and after observing that water is discharged from the drain pipe 13, the box 11 is lifted upward, the liquid level sensor 5 loses contact with the water and the float swings downward, at this time the liquid level sensor 5 loses the triggered electrical signal, and the control unit controls the water pump 4 to close accordingly. It can be seen that the structure of the liquid level sensor 5 can realize automatic water pumping by placing the box 11 under the breeding pond and pressing it down until the lower half of the box 11 is below the liquid level, and after the box 11 is lifted out of the water surface of the breeding pond, the water pump 4 can be automatically closed. This control method makes the water sample collection process more convenient than the manual operation method.

[0036] In addition, preferably, a water quality monitoring sensor can also be fixed in the middle of the threaded sleeve 21. When the water in the collection bottle 3 is filled to overflow the water quality monitoring sensor, the water quality monitoring sensor can detect parameters such as water temperature and oxygen content, which are then processed by the control unit and displayed on the operation panel.

[0037] In summary, when using the utility model to collect water samples, only need to press down the box body 11 until a part of the bottom is below the water level of the aquaculture pond, so that the water inlet pipe 12 enters the aquaculture pond, and then control the water pump 4 to pump water, then the water in the aquaculture pond can be pumped upward through the water inlet pipe 12 and enter the collection bottle 3 through the first connecting pipe 22. When it is observed that water is discharged from the drain pipe 13, it indicates that the collection bottle 3 is already full of water samples. At this time, turn off the water pump 4 and lift the box body 11 upward. Thus, the water quality sampling is completed. This collection process only needs to grasp the upper part of the box body 11, without reaching into the water to lift the box body 11, so the hands will not be wet, and thus it is more convenient. The above is only the specific implementation manner of the utility model, but the design concept of the utility model is not limited thereto. Any non-substantive modification of the utility model using this concept shall belong to the act of infringing the protection scope of the utility model.
