Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detectors, and particularly relates to a water quality detector for freshwater aquaculture. Background Art

[0002] A water quality detector is a professional instrument for analyzing the content of water quality components, mainly referring to instruments for measuring items such as BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, PH, dissolved oxygen, etc. in water. In freshwater aquaculture, a water quality detector is an extremely important device because water quality is the key to determining the growth and reproduction of animals and plants. Timely understanding of the on-site water quality conditions and water quality parameters such as temperature, salinity, acidity, and dissolved oxygen and their changes play a decisive role in the quality of aquaculture. However, when common water quality detectors are used, the probe needs to be put into the water for detection. Since the probe will keep sinking in the water, it will cause the device to be inconvenient for detecting water quality at different depths. It is necessary to drag the data cable to make the probe sink and be fixed at different depths in the water, resulting in a more inconvenient process for detecting water quality. For this reason, this application proposes a water quality detector for freshwater aquaculture. Content of the Utility Model

[0003] To solve the problems raised in the above background art, the utility model provides the following technical solution: A water quality detector for freshwater aquaculture, including a main body and a probe. The top end of the probe is fixedly connected with a data cable. At the end of the data cable far from the probe, a connector is fixedly installed. The data cable is connected to the top end of the main body through the connector. A floating ball is movably sleeved on the data cable. The floating ball is set as a hollow spherical ball. A fixed pipe is fixedly installed between the top and bottom of the inner wall of the floating ball. Through holes communicating with the top and bottom of the fixed pipe are respectively provided at the top and bottom of the floating ball. The data cable is inserted through the through holes at the top and bottom of the floating ball and between the fixed pipes.

[0004] Preferably, a connecting pipe is fixedly installed at the bottom of the floating ball. The connecting pipe is sleeved on the data cable. A crack is provided at the end of the connecting pipe far from the floating ball. The crack divides the end of the connecting pipe far from the floating ball into two symmetrically left and right parts on average. A rotating ring is threadedly sleeved on the outer wall of the connecting pipe. And rubber pads are fixedly installed on both sides of the inner wall of the end of the connecting pipe far from the floating ball. Both rubber pads are in contact with the outer wall of the data cable. The connecting pipe is made of plastic.

[0005] Preferably, when the rotating ring is located at the end of the connecting pipe close to the floating ball, the rotating ring does not cover the crack at one end of the connecting pipe. The outer diameter of the end of the connecting pipe far from the floating ball is greater than the inner diameter of the rotating ring.

[0006] Preferably, a T-shaped handle is fixedly installed at the middle position of the back of the main body. One end of the vertical part of the handle is fixedly connected to the back of the main body. The front of the main body is provided as a display screen.

[0007] Preferably, the surface of the data line is provided with scale markings.

[0008] Preferably, the two ends of the fixed tube are hermetically connected to the inner wall of the floating ball.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] By screwing the rotating ring to move it to the end of the connecting pipe away from the floating ball, the rotating ring will close the split end of the connecting pipe together, making the two rubber pads on the inner wall of the connecting pipe closely adhere to the outer wall of the data line, adjusting the position of the floating ball on the data line so that the floating ball floats on the water surface, enabling the probe at one end of the data line to sink to a fixed depth in the water, and thus enabling the probe to detect the water quality at different depths.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] ByFigures 1-5 Given that, the utility model includes a main body 1 and a probe 3. A data cable 4 is fixedly connected to the top end of the probe 3. A connector 5 is fixedly installed at the end of the data cable 4 away from the probe 3. The data cable 4 is connected to the top end of the main body 1 through the connector 5. A floating ball 6 is movably sleeved on the data cable 4. The floating ball 6 is set as a hollow spherical ball. A fixed tube 7 is fixedly installed between the top and bottom of the inner wall of the floating ball 6. Through holes 12 communicating with the top and bottom of the fixed tube 7 are respectively provided at the top and bottom of the floating ball 6. The data cable 4 is inserted through the through holes 12 at the top and bottom of the floating ball 6 and between the fixed tube 7. By adjusting the position of the floating ball 6 on the data cable 4, the length of the data cable 4 passing through the fixed tube 7 is the depth to be measured of the probe 3. Then, turn the rotating ring 10 to move it to the end of the connecting pipe 8 away from the floating ball 6. The rotating ring 10 will close the split end of the connecting pipe 8 together, so that the two rubber pads 9 on the inner wall of the connecting pipe 8 are closely attached to the outer wall of the data cable 4, thereby preventing the data cable 4 from moving within the connecting pipe 8. Then, the probe 3 can be put into water. The floating ball 6 will float on the water surface, so that the probe 3 is at the depth to be measured in the water and cannot sink further.

[0020] At the same time, a connecting pipe 8 is fixedly installed at the bottom of the floating ball 6. The connecting pipe 8 is sleeved on the data cable 4. A crack is provided at the end of the connecting pipe 8 away from the floating ball 6. The crack divides the end of the connecting pipe 8 away from the floating ball 6 into two symmetrically left and right parts on average. A rotating ring 10 is threadedly sleeved on the outer wall of the connecting pipe 8. And rubber pads 9 are fixedly installed on both sides of the inner wall of the connecting pipe 8 away from the floating ball 6. Both rubber pads 9 are in contact with the outer wall of the data cable 4. The connecting pipe 8 is made of plastic material. In this way, when the connecting pipe 8 is not squeezed by the rotating ring 10, the split end of the plastic connecting pipe 8 is easily in a loose and separated state, so that the rubber pads 9 on both sides of the inner wall of the connecting pipe 8 do not contact the outer wall of the data cable 4.

[0021] In addition, when the rotating ring 10 is located at the end of the connecting pipe 8 close to the floating ball 6, the rotating ring 10 does not cover the crack at one end of the connecting pipe 8. The outer diameter of the end of the connecting pipe 8 away from the floating ball 6 is larger than the inner diameter of the rotating ring 10. In this way, the rotating ring 10 will not squeeze the split end of the connecting pipe 8, so that the two parts of the split end of the connecting pipe 8 can be in a loose state, and then the data cable 4 can be pulled to move between the fixed tube 7 and the connecting pipe 8.

[0022] Moreover, a T-shaped handle 11 is fixedly installed at the middle position of the back surface of the main body 1. One end of the vertical part of the handle 11 is fixedly connected to the back surface of the main body 1. A display screen 2 is arranged on the front surface of the main body 1. By winding the data cable 4 around the vertical part of the handle 11, the storage of the data cable 4 can be completed when the device is not in use.

[0023] In addition, the surface of the data line 4 is provided with scale markings. Through the scale markings on the surface of the data line 4, the bottom of the floating ball 6 is positioned at the depth to be measured, so that the depth of the probe 3 sinking in the water can be adjusted.

[0024] Furthermore, both ends of the fixed pipe 7 are hermetically connected to the inner wall of the floating ball 6 to prevent water from seeping into the cavity inside the floating ball 6. Once water seeps in, the floating ball 6 will not be able to float on the water surface.
