Specifically, the control module may be electrically connected with the spectrum sensor 72, the conductivity sensor 73, the water pressure sensor 74, the cleaning brush 75, the inertial measurement unit, and the control unit. The housing 71 may include a body 711, a mount 712, and a filter housing 713. The body 711 may have a cylindrical shape, and an accommodating space 71a is defined therein. One end of the body 711 is open, and the other end of the body 711 is provided with a ring portion 71b.

One end of the sleeve is open and the other end is closed, and the open end of the sleeve may be sealingly connected to a mounting seat 712. Thus, even if water enters the receiving space 71a from the mounting hole 71d, the water can be confined in the sleeve without affecting other components, so that the sealing effect of the spectrum sensor 72, the conductivity sensor 73, and the water pressure sensor 74 with the mounting seat 712 can be improved.

A plurality of seal rings, for example, two seal rings, may be provided between the outer circumferential surface of the water pressure sensor 74 and the inner circumferential surface of the mounting hole 71 d. Accordingly, the spectrum sensor 72, the conductivity sensor 73, and the cleaning brush 75 may be fixedly and sealingly connected with the mounting seat 712 in a similar manner as the water pressure sensor 74.

Further, the threaded portion 71e may be interrupted, and the central axis of the threaded bore 71f may be aligned with the interruption of the threaded portion 71e. In this way, the tool for turning the screw can easily turn the screw from the discontinuity.

The cleaning brush 75 can include a motor 751, a coupling 752, a drive shaft 753, a dynamic seal structure 754, and a brush head 755.

Specifically, the first case 11 may enclose a battery receiving chamber 11a, and the battery receiving 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 fixing holes 11d. Fasteners may be passed through the fixing holes 11d so that the first casing 11 can be fixed to the wall of the borehole. Two eye rings 14 may be mounted to the flange 11c and a rope may be passed through the eye rings 14.

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 to bring the first abutting portion 12b into abutment with 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 only be screwed by a special tool matched with the first antitheft screw, so that the battery 3 is not easy to lose.

The second box 21 may be opened with an adjusting hole 2a, and the adjusting hole 2a may be a kidney-shaped hole. The stopper 24 may pass through the adjustment hole 2a and the wall portion of the first case 11, so that the second case 21 can rotate about the stopper 24 and can move in the extending direction of the adjustment hole 2a with respect to the first case 11. The locking member may be engaged with the retaining member 24 so that the second casing 21 is fixed to the first casing 11. For example, the retaining member 24 may be a bolt and the retaining member may be a nut.

The second cover 22 may include a second pivot portion 22a and a second abutment portion 22b. 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 control component 4 can be received in the main control receiving cavity 21a, and the user can rotate the second cover 22 to separate the second abutting portion 22b from the second box 21, so that the control component 4 can be taken out from the main control receiving cavity 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 control assembly 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 a second antitheft screw 23, so that the control assembly 4 is not easily lost.

The directional antenna 6 may be mounted to the first mounting box 1. Specifically, the directional antenna 6 may be threadably connected with the first cover 12 such that the directional antenna 6 is integrally rotatable 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.

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

The method of use of the water quality monitoring apparatus is described below.

The user can put the water quality monitoring equipment into the tube well through the rope. Wherein the first installation case 1 can be fixed on the well wall at a position close to the well head. The air pressure sensor can measure the air pressure at the position where the air pressure sensor is located, and the flow velocity sensor can measure the flow velocity of the water body. The probe 7 may be wholly or partially submerged in a body of water, which may enter the sample introduction space from the sample introduction hole 71c, so that the spectroscopic sensor 72, the conductivity sensor 73 and the water pressure sensor 74 can come into contact with the body of water. Impurities in the water may be filtered out by the filter housing 713. After the water quality monitoring equipment reaches the designated position, the user can be fixed in the well head of tube well with the rope.

The inertial measurement unit can measure the attitude angle of the probe 7 when impacted by the water body, and the user can calculate the first distance between the water pressure sensor 74 and the bottom of the pipe well according to the attitude angle of the probe 7 and the length of the rope. The water pressure sensor 74 may measure the water pressure at the depth based on the measurement result of the air pressure sensor, and the user may calculate the second distance between the water pressure sensor 74 and the water surface according to the water pressure. The water depth of the water body can be obtained by summing the first distance and the second distance, and the user can obtain the cross-sectional area of the water body according to the water depth and the shape of the pipeline. After the flow velocity and the cross-sectional area of the water body are obtained, a user can calculate the flow of the water body. By comparing the measured flow with the target flow, the user can determine whether the pipe has leakage, misconnection, and the like.

The spectral sensor 72 can detect parameters of the water body such as Chemical Oxygen Demand (COD), turbidity (FTU), permanganate, biochemical Oxygen Demand (BOD), and Total Organic Carbon (TOC), and the conductivity sensor 73 can detect the conductivity of the water body. The user can judge the water quality of the water body according to the detection results of the spectrum sensor 72 and the conductivity sensor 73. The motor 751 can drive the brush head 755 to rotate back and forth, and the brush head 755 can contact with the lens of the spectrum sensor 72 during rotation to clean the lens.

In this way, by integrating the spectrum sensor 72 and the conductivity sensor 73 for measuring water quality with the flow rate sensor, the air pressure sensor, and the water pressure sensor for measuring flow rate, the water quality monitoring apparatus can monitor the connection condition (leakage, misconnection, etc.) of the pipes while monitoring the water quality. In addition, the sensor for measuring water quality and the sensor for measuring flow can share energy equipment and transmission equipment, so that the use cost of the water quality monitoring equipment can be reduced.
