It can be used to monitor chemicals, microorganisms, heavy metals, organic matter in water, as well as water temperature, pH value, and turbidity indicators. Therefore, in aquaculture, water quality monitoring equipment can effectively improve aquaculture efficiency, reduce risks, and increase the quality and output of aquaculture.

[0003] Existing water quality monitoring equipment usually places a single water quality sensor in the water quality monitoring equipment directly into the water area to be monitored for monitoring. It can only monitor the water samples around the water quality sensor, and cannot simultaneously monitor water samples at different depths in the measured water area. It has a single function and it is difficult to obtain water samples at different depths. When sampling water quality, it is necessary to use a sampling tube to repeatedly collect water samples at different depths.

[0004] Therefore, the utility model provides a water quality monitoring device with a sampling function to solve the problems raised in the above background technology. Utility Model Content

At the same time, the gears, outer cylinder and rack arranged in equal proportions enable the water intake mechanism to extract water samples of different depths into multiple cavities, which is convenient for monitoring water samples of different depths and more convenient for obtaining water samples of different depths.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water quality monitoring device with a sampling function, comprising a box body, a plurality of water pipes are evenly spaced through the lower side of the front end face of the box body, a valve is fixedly arranged in the middle of one side of the plurality of water pipes, a plurality of water quality sensors are arranged on the rear end face of the box body, a support baffle is fixedly arranged in the middle of the inner part of the box body, a motor is arranged in the middle of one side of the upper end face of the support baffle, a rotating shaft is fixedly arranged at the output end of the motor, a plurality of gears are sleeved on the circumference of the rotating shaft, a first cavity, a second cavity and a third cavity are evenly opened on the support baffle and the lower end face of the inner part of the box body, a plurality of water intake mechanisms are arranged through the rear side of the lower end face of the box body, The water intake mechanism includes an outer cylinder, a first rubber plug, a fifth hole groove, a rack, a spring and a second rubber plug. The upper ends of the multiple outer cylinders are penetrated in the first cavity, the second cavity and the third cavity inside the box body. The multiple outer cylinders are respectively penetrated in the first cavity, the second cavity and the third cavity. The multiple second rubber plugs are respectively embedded in the lower side of the inner part of the outer cylinder. The lower end surfaces of the multiple springs are respectively fixed on the upper end surfaces of the second rubber plugs. The multiple first rubber plugs are respectively fixed on the upper end surfaces of the springs. The multiple fifth hole grooves are opened on the circumference of the lower end of the outer cylinder. The multiple racks are respectively fixed on the upper end surfaces of the first rubber plugs. The multiple racks are respectively penetrated in the inner part of the box body and meshed with the gears.

[0007] Through the above technical scheme, it is convenient to take out water samples at any time through the valve, and it is convenient to monitor water samples at different depths simultaneously through multiple water quality sensors. The motor is used as a power source. When the water quality monitoring equipment is working, the output end of the motor drives the rotating shaft to rotate, and then drives multiple gears on the rotating shaft to rotate.

[0009] Through the above technical solution, the first hole groove and the third hole groove facilitate the rack to move up and down inside the box, thereby increasing the lifting space of the rack.

[0010] Furthermore, fixing plates are fixedly arranged on both sides of the rear end surface of the box body, and second holes are penetrated on both upper and lower sides of the front and rear end surfaces of the fixing plates;

[0011] Through the above technical solution, the entire water quality monitoring device can be easily fixed by the fixing plate and the second hole groove, which facilitates the operation of the water quality monitoring device.

[0012] Furthermore, a plurality of the racks are provided with a plurality of sleeves on the upper sliding sleeve, and the lower end surfaces of the plurality of sleeves are fixedly connected to the support baffle;

[0014] Furthermore, a plurality of sampling and placing tables are fixedly arranged on the front side of the lower end face of the box body;

[0015] The above technical solution makes it easy to place the sampler to extract water samples from the first cavity, the second cavity and the third cavity.

[0017] Through the above technical solution, when the water intake mechanism extracts water samples from the water area, the ramp plate makes the water in the first cavity, the second cavity and the third cavity gather on one side, so as to facilitate the discharge of water samples through multiple cavities. The outer cylinder passes through the fourth hole groove to prevent the water in multiple cavities from being filled up due to long-term operation, which makes the water quality monitoring equipment unable to work.

[0018] Furthermore, the pitches of the gears are proportionally enlarged, and the lengths of the outer cylinders and the racks are proportionally extended;

[0019] Through the above technical solution, the pitches of multiple gears are proportionally enlarged, and the lengths of the outer cylinder and the rack are proportionally extended, so that when the motor rotates, multiple first rubber plugs can reach multiple cavities at the same time, realizing the function of simultaneously sampling water quality at different depths.

[0033] The valve 5 can be used to open and close the water pipe 6 at any time, so that the water sample can be taken out at any time. The multiple water quality sensors 12 can be used to simultaneously monitor the water samples in the first cavity 17, the second cavity 18 and the third cavity 19, so as to realize the function of simultaneously monitoring water samples at different depths. The motor 21 is used as a power source. When the water quality monitoring equipment is working, the output end of the motor 21 drives the rotating shaft 13 to rotate, and then drives the multiple gears 15 on the rotating shaft 13 to rotate. The gear 15 is meshed with the rack 804. The rotation of the gear 15 causes the rack 804 to move upward. The upward movement of the rack 804 pulls the first rubber stopper 802 upward, and the third rubber stopper 802 moves upward. A rubber plug 802 pulls the second rubber plug 806 upward through the spring 805, and friction is generated between the second rubber plug 806 and the inner wall of the outer tube 801. The spring 805 is ductile, and the extended length of the spring 805 causes the second rubber plug 806 to be pulled away from the first rubber plug 802 to form a cavity.

[0034] The upper end surface of the box body 1 is penetrated with a plurality of first holes 2 at equal intervals, and the middle part of the support baffle 20 is penetrated with a plurality of third holes 9 at equal intervals. A plurality of racks 804 are respectively penetrated inside the first holes 2 and the third holes 9. Through the first holes 2 and the third holes 9, it is convenient for the racks 804 to move up and down inside the box body 1, and the working space for the up and down movement of the racks 804 is increased, which is convenient for the water taking mechanism 8 to obtain water samples into the plurality of cavities.

The lower end surface of the sleeve 16 is fixed on the support baffle 20, and the upper end is sleeved with a rack 804. On the one hand, the stability of the rack 804 is improved, and on the other hand, the position of the rack 804 is prevented from moving when it moves up and down, causing it to be unable to mesh with the gear 15. Multiple sampling placement tables 7 are fixedly arranged on the front side of the lower end face of the box body 1, which is convenient for placing sampling containers and extracting water samples from the first cavity 17, the second cavity 18, and the third cavity 19 at the same time, reducing the difficulty of work;

The ramp plate 11 is convenient for the water taking mechanism 8 to obtain water samples from the water area, so that the water in the first cavity 17, the second cavity 18, and the third cavity 19 is gathered on one side. On the one hand, when the second rubber stopper 806 moves to the fourth hole groove 10, the water sample between the first rubber stopper 802 and the second rubber stopper 806 will flow smoothly. The water is collected into the cavity by the ramp plate 11, and on the other hand, it is convenient for multiple cavities to discharge water samples through the water pipe 6. The outer cylinder 801 passes through the fourth hole groove 10 to prevent the water in multiple cavities from working for a long time and causing the water in the cavity to be full and causing the water quality monitoring equipment to be unable to work. When the height of the water in the cavity is higher than the fourth hole groove 10, when the first rubber plug 802 and the second rubber plug 806 are still moving up and down, part of the water in the cavity will also flow into the cavity formed by the first rubber plug 802 and the second rubber plug 806 to reach a balanced state, avoiding excessive water accumulation in the cavity and causing it to be unable to work;

[0036] The pitches of the gears 15 are proportionally enlarged, the lengths of the outer cylinders 801 and the racks 804 are proportionally extended, and the pitches of the gears 15 are proportionally enlarged, so that the circumference of each gear 15 is proportionally extended, and then when the shaft 13 rotates, the distance each rack 804 moves upward is proportionally moved, and because the length of the outer cylinder 801 is proportionally extended to the length of the rack 804, the longer the rack 804 is, the larger the pitch of the meshing gear 15 is, and when the motor 21 rotates, the first rubber plugs of the water intake mechanism 8 of different lengths are 802 can move upward in proportion to reach the first cavity 17, the second cavity 18 and the third air conditioner at the same time, so as to realize the function of simultaneously obtaining water samples of different depth layers. A shaft sleeve 14 is sleeved on the other side of the rotating shaft 13, and the lower end of the shaft sleeve 14 is fixedly arranged in the middle part of the other side of the upper end surface of the supporting baffle 20. The lower end of the shaft sleeve 14 is fixedly connected to the supporting baffle 20, and the upper end of the shaft sleeve 14 is sleeved on the rotating shaft 13. Through the shaft sleeve 14, the stability of the rotating shaft 13 is improved, thereby improving the stability and accuracy of the water intake mechanism 8.

[0037] Working principle: When the water quality monitoring equipment is working, the outer cylinder 801 is placed in the water, and the output end of the motor 21 drives the rotating shaft 13 to rotate, and then drives the multiple gears 15 on the rotating shaft 13 to rotate, and the gear 15 is meshed with the rack 804 to make the rack 804 move upward, and the rack 804 moves upward to pull the first rubber plug 802 to move upward, and the first rubber plug 802 pulls the second rubber plug 806 to move upward through the spring 805, and the second rubber plug 806 and the inner wall of the outer cylinder 801 will generate friction, and the spring 805 can extend the length to make the second rubber plug 806 move slower than the first rubber plug 802, and at the same time, water will enter the outer cylinder 801 along the fifth hole groove 803. When the second rubber plug 806 moves to a position higher than the fifth hole groove 803 to seal the water inside the outer cylinder 801, The motor 21 rotates and continuously moves upward to the first cavity 17, and multiple outer cylinders 801 and gears 15 are proportionally expanded to achieve the function of sampling water samples at different depths. At the same time, the water sample is monitored according to the water quality sensor 12 arranged in the first cavity 17 to transmit information, and then the motor 21 rotates in the opposite direction to make the second rubber plug 806 move toward the lower end of the outer cylinder 801 to realize the round-trip extraction of water samples. When it is necessary to extract water samples at different depths, the beaker is placed on the sampling placement table 7, the valve 5 is opened, and the water sample in the cavity is discharged. When the water level in the cavity is higher than the fourth hole 10, the water sample will be continuously transported up and down between the first rubber plug 802, the second rubber plug 806 and the outer cylinder 801 to form a balanced state, and the cavity will not be filled with water and unable to work.
