[0028] EMBODIMENT

[0029] As Figures 1-4 shown in the figure, the mounting frame 1 is arranged at the wellhead of the monitoring well, and the specific structure of the mounting frame 1 is that the mounting frame 1 comprises a support cylinder 11 coaxially arranged with the wellhead, and the support cylinder 11 is inserted into the ground and provided with an annular support plate 12 on the outer side to abut against the ground, that is, as Figure 2 shown in the figure, in this state, the mounting frame 1 is stable in structure, and it is necessary to ensure that the annular support plate 12 is in a horizontal state to ensure the accuracy of the monitoring information, and then the mounting frame 1 comprises a support cover plate 13 which is arranged above the wellhead and can be turned over, and the support cover plate 13 is normally connected with a plurality of fixed columns arranged around the outer wall of the support cylinder 11 by bolts to ensure that the two are in a fixed state, in this state, the support cover plate 13 can always be in a horizontal state, and it can only be opened when the monitoring well needs to be cleaned or other operations are performed.

[0030] Afterwards, the upper part of the support cover plate 13 is provided with the cabinet 2, and the upper part of the cabinet 2 is provided with the monitoring host 4, which is used for monitoring various required information, including water level and pH value, etc. Since the monitoring host 4 is of a conventional structure, it will not be described here again. It should be noted that the difference between the monitoring host 4 of the present device and the existing monitoring host 4 is only that the former is detachably connected with the metering device 64, instead of being of an integral structure.

[0031] Since the metering device 64 needs to be deeply submerged in water, in order to reduce the working pressure of the staff, the cabinet 2 is further provided with a retracting mechanism 5, which is provided with a horizontal rotating shaft 52 capable of rotating, and the rotating shaft 52 is detachably sleeved with a replaceable metering mechanism 6 capable of rotating synchronously with the rotating shaft 52. By driving the rotation of the rotating shaft 52, the metering device 64 can be retracted or extended. When it is extended, it can be deeply submerged in water, and when it is retracted, it can be replaced, repaired, etc. As shown in Figure 3 、 5 , the specific structure of the retracting mechanism 5 is that the retracting mechanism 5 comprises a reference seat 51 fixed on the cabinet 2 by bolts, and the position is fixed. The rotating shaft 52 is inserted into the reference seat 51 and can rotate. The end of the rotating shaft 52 away from the replaceable metering mechanism 6 is connected with the output end of the driving motor 54 through the belt 53. Therefore, by starting the driving motor 54, the driving rotation of the rotating shaft 52 can be realized. Moreover, in the case that the driving motor 5 is a servo motor, the extension height of the metering device 64 can also be controlled by the above-mentioned method.

[0032] It should be noted that, as shown in Figure 4 、 6 , the replaceable metering mechanism 6 comprises a winding drum 61, on which a cable 62 is wound, as shown in Figure 6 . One end of the cable 62 is the metering device 64, and the other end is the terminal 63, which can be detachably connected with the terminal port 41 of the monitoring host 4. The metering device 64 can pass through the opening of the cabinet 2 and the support cover plate 13 and be deeply submerged below the liquid level of the monitoring well. Therefore, the cabinet 2 and the support cover plate 13 need to be provided with openings to ensure that the metering device 64 can be extended.

[0033] Moreover, in the above structure, in order to ensure the synchronization of the rotating shaft 52 and the winding drum 61, the contact surface of the rotating shaft 52 and the winding drum 61 is of a non-circular structure. After being inserted and combined, they can rotate synchronously, as shown in Figure 6 . The center of the winding drum 61 has a non-circular opening. After being inserted with the matched rotating shaft 52, synchronous rotation can be realized. Moreover, in order to fix them, as shown in Figure 5As shown, the end of the rotating shaft 52 away from the belt 53 is also provided with a threaded column, which can be provided with a nut, and the nut cannot pass through the non-circular hole. In this way, as Figure 4 As shown, the end of the rotating shaft 52 away from the belt 53 is also provided with a threaded column, which can be provided with a nut, and the nut cannot pass through the non-circular hole. In this way, as

[0034] Through the above structure, unlike existing devices, the device can directly replace the replacement metering mechanism 6, so during inspection, it is not necessary to detect whether the metering instrument 64 has a problem, but to directly replace it, and then the maintenance process can be carried out in a professional place, the inspection speed is faster, only need to control the rotating shaft 52 to rotate to collect the replacement metering mechanism 6, then disassemble the wiring terminal 63 relative to the wiring port 41, and then disassemble it by disassembling the nut, then install the new problem-free replacement metering mechanism 6 and tighten the nut, then put down the wiring terminal 63 relative to the wiring port 41.

[0035] In addition to the above structure, as a preferred embodiment, in order to facilitate the installation of the wiring terminal 63, the winding reel 61 is provided with a sink groove, and the cable 62 is inserted into the sink groove and fixed with the winding reel 61. By setting the sink groove, the cable 62 can be avoided when winding the wiring terminal 63.

[0036] And in order to monitor various information, the monitoring host 4 includes a plurality of wiring ports 41, and the replacement metering mechanism 6 is provided with a plurality of rotating shafts 52, and the metering instruments 64 of the plurality of replacement metering mechanisms 6 are different, and the wiring ports of the monitoring host 4 also correspond to different functions. In this way, the replacement of multiple functional structures can be realized at the same time, and it is very convenient, which simplifies the inspection process.

[0037] As a preferred way, in terms of existing conventional devices, the metering instrument 64 is a drop-in pressure water level meter or a drop-in PH meter, which can monitor water level and pH information. If other functions are also needed, they can be selected and installed according to needs.

[0038] Finally, in order to power, the cabinet 2 is provided with a photovoltaic panel 3 above.
