(first embodiment)

Fig. 1 to 4 show a water quality monitoring apparatus according to a first embodiment of the present application, particularly a water quality monitoring apparatus for a tube well. The tube well may be connected to a pipeline in which a body of water may flow. For example, in this embodiment, the tube well may extend vertically, the pipeline may extend horizontally, and the tube well may meet the pipeline to form an inverted T-shape.

The water quality monitoring device may include a first mounting box 1, a second mounting box 2, a battery 3, a controller 4, a cable 5, a directional antenna 6, and a probe 7.

The first mounting case 1 may include a first case 11, a first cover 12, first antitheft screws 13, and a hanging ring 14. Specifically, the first case 11 may enclose a battery housing chamber 11a, and the battery housing chamber 11a may communicate with the outside of the first case 11 through a battery mounting port 11 b. The wall portion of the first case 11 may be provided with a flange 11c, and the flange 11c may be obtained by bending the wall portion into a substantially U-shape. The flange 11c may be formed with two through mounting holes 11d. Fasteners may be passed through the mounting holes 11d to enable the first casing 11 to be secured to the borehole wall. Two eye rings 14 may be mounted to the flange 11c and a rope may be passed through the eye rings 14. The user can put the water quality monitoring equipment into the tube well through the rope, or take the water quality monitoring equipment out of the tube well through the rope.

The first cover 12 may include a first pivot portion 12a and a first abutment portion 12b. The first pivot portion 12a may be formed as a part of a hinge, and another part of the hinge may be fixed with the first case 11. The first abutting portion 12b may abut against the flange 11c. The battery 3 can be housed in the battery housing chamber 11a. For example, the cells 3 may be intrinsically safe battery packs, so that the water quality monitoring device may be used in a tube well in which combustible gas is present. The user can rotate the first cover 12 to separate the first abutting portion 12b from the flange 11c, thereby taking out the battery 3 from the battery housing chamber 11a. Alternatively, the user may rotate the first cover 12 so that the abutting portion abuts against the flange 11c, thereby being able to restrain the battery 3 within the battery housing chamber 11a.

Further, the first abutting portion 12b may be screwed with the first case 11 by a first antitheft screw 13. The first antitheft screw 13 can be screwed only by a special tool matched with the first antitheft screw, so that the battery 3 is not easy to lose.

The second mounting box 2 may include a second box body 21, a second box cover 22, a second antitheft screw 23, a stopper 24, and a locking member. Specifically, the second casing 21 may enclose a main control accommodation cavity 21a, and the main control accommodation cavity 21a may communicate with the outside of the second casing 21 through a main control installation opening 21 b. The bottom of the second casing 21 may be provided with a light-transmitting region 21d through which light passes 21d.

The second pivot portion 22a may be formed as a part of the hinge, and another part of the hinge may be fixed with the second casing 21. The second abutting portion 22b may abut against the second case 21. The controller 4 can be accommodated in the main control accommodation chamber 21a, and the user can rotate the second cover 22 to separate the second abutting portion 22b from the second case 21, so that the controller 4 can be taken out of the main control accommodation chamber 21 a. Alternatively, the user may rotate the second cover 22 to make the second abutting portion 22b abut against the second case 21, so that the controller 4 can be confined in the main control accommodation chamber 21 a. Similarly, the second abutting portion 22b may be screwed with the second case 21 by the second antitheft screw 23, so that the controller 4 is not easily lost.

The controller 4 may include a housing 41, a control unit, a camera 42, and a light source 43. Specifically, the control unit, the camera 42 and the light source 43 may be located inside the housing 41, and the camera 42 and the light source 43 may be electrically connected with the control unit. The camera 42 and the light source 43 can be aligned with the light-transmitting region 21d so that the camera 42 can photograph the inside of the well, and the light source 43 can provide illumination for the camera 42. When the shooting angle of the camera 42 needs to be adjusted, the user can adjust the posture of the second casing 21.

The casing 41 is further provided with a plurality of terminals, and the control unit can be connected with the battery 3, the directional antenna 6 and the probe 7 respectively after being connected with the cable 5 through different terminals. Wherein, the battery 3 can supply power to the whole water quality monitoring equipment. The control unit can exchange data with the directional antenna 6, the camera 42 and the probe 7, and images shot by the camera 42 and data collected by the probe 7 can be transmitted through the directional antenna 6.

The directional antenna 6 may be mounted to the first mounting box 1. Specifically, the directional antenna 6 may be screwed with the first cover 12 such that the directional antenna 6 can be integrally rotated with the first cover 12. The directional antenna 6 may be a flat antenna that may be mounted in parallel to the mounting surface of the first cover 12. When the first abutting part 12b abuts against the flange 11c, the maximum radiation direction and the maximum receiving direction of the directional antenna 6 may be the same as the depth direction of the pipe well, so that the signal of the antenna is not blocked by the well wall, and thus the water quality monitoring device can smoothly communicate with the upper computer.

The probe 7 can be used for monitoring the content of ammonia nitrogen in the water body. Specifically, the lower portion of the probe 7 may be provided with an injection port 7a, and a water sample can enter the inside of the probe 7 through the injection port 7 a. The probe 7 may have a conversion unit and a detection unit mounted therein. The conversion module may be a photolysis module, which may include a photolysis catalyst and a photolysis light source, or an electrolysis module, which may include a cathode electrode and an anode electrode. The detection assembly may include one or more of an electrode-type conductivity sensor, an inductive-type conductivity sensor, a pH sensor, and a capacitive sensor. A cable connected to the controller 4 may extend from an upper portion of the probe 7 into the interior of the probe 7.

In this way, by housing the battery 3 and the controller 4 in different chambers, the user can separately maintain the battery 3 and the controller 4.
