Real-time monitoring of groundwater levels, water temperature, pH value, conductivity and quality data provides effective data support for the comprehensive management of groundwater resources.

[0003] Water environment monitoring base stations in the prior art usually monitor water quality through a single sensor. The monitoring position of the sensor needs to be adjusted in real time by the staff, which is time-consuming and labor-intensive. The monitoring range is small.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 2. Through the design of the cross bar and the extrusion plate, when the second elastic member is in a contracted state, the cooperation between the convex shaft and the V-shaped groove can keep the two extrusion plates in a horizontal state, so that groundwater can smoothly enter the collection box, and the filter plate can collect impurities in the groundwater. Through the design of the first elastic limit pin, when the first elastic limit pin is inserted into the limit hole of the filter plate, the filter plate can be kept in a vertical state, so that the cross bar and the two extrusion plates can squeeze the impurities on the front side of the filter plate, thereby effectively improving the accuracy of monitoring the impurity content in the groundwater.

[0018] 3. The present invention designs the second cleaning frame. During the rotation of the impeller, the second cleaning frame can slide along the blade surface of the impeller through the cooperation of the sliding shaft and the arc rod to clean the impeller surface impurities or minerals, thereby preventing the impeller surface from being excessively covered with impurities or minerals, which would reduce the rotation efficiency of the impeller.

An installation box 207 is provided below the reciprocating lead screw 202. An impeller 208 is rotatably connected inside the installation box 207. The wheel shaft of the impeller 208 rotatably penetrates through the installation box 207 and is fixedly connected to the bottom end of the reciprocating lead screw 202.

[0034] As Figure 2-Figure 4As shown, the impurity monitoring mechanism further includes a cross bar 301. The inner wall of the collection box 204 is horizontally and slidably connected with the cross bar 301. A second elastic member is arranged between the cross bar 301 and the inner wall of the collection box 204. The second elastic member is a tension spring. The cross bar 301 is symmetrically hinged with pressing plates 302. Convex shafts are fixedly connected to both sides of the pressing plates 302. Two groups of V-shaped grooves are symmetrically formed on the inner wall of the collection box 204, with two in each group. The convex shafts are clamped into the corresponding V-shaped grooves and slide therein. A horizontal shaft is fixedly connected to the front side of the cross bar 301. A second sensor 303 is installed on the horizontal shaft. The second sensor 303 is electrically connected to the base station body 1. A third elastic member is arranged between the second sensor 303 and the cross bar 301. The third elastic member is sleeved on the outer wall of the horizontal shaft of the cross bar 301. The third elastic member is a compression spring. Through grooves are formed through both sides of the collection box 204. Slide shafts 304 are fixedly connected to both sides of the second sensor 303. The slide shafts 304 are clamped into the through grooves and slide therein. T-shaped rods 305 are symmetrically fixedly connected to the bottom of the installation box 207. The T-shaped rods 305 are used in cooperation with the slide shafts 304. A flow plate is fixedly connected to the bottom of the collection box 204.

[0035] As Figure 5 shown, the impurity monitoring mechanism further includes a first elastic limit pin 401. The top of the collection box 204 is vertically and slidably connected with the first elastic limit pin 401 in a penetrating manner symmetrically. Limit holes for cooperating with the first elastic limit pin 401 are symmetrically formed on the top of the filter plate 205. When the first elastic limit pin 401 is inserted into the limit holes of the filter plate 205, the filter plate 205 can be limited.

[0036] As Figure 4 with Figure 5 shown, the impurity monitoring mechanism further includes a U-shaped rod 501. The U-shaped rod 501 is horizontally slidably connected to the collection box 204. Both slide shafts 304 are fixedly connected to the U-shaped rod 501 in a penetrating manner. An irregular-shaped frame 502 is fixedly connected to the top of the U-shaped rod 501. A push plate 503 is hinged to the rear end of the irregular-shaped frame 502. An unlocking rod 504 is horizontally slidably connected to the top of the collection box 204. Protruding shafts for cooperating with the unlocking rod 504 are fixedly connected to the sides of the two first elastic limit pins 401 close to each other. A rotating disk 505 is rotatably connected to the top of the unlocking rod 504. Four uniformly distributed push rods 506 are fixedly connected to the outer wall of the rotating disk 505. The four push rods 506 are used in cooperation with the push plate 503.

[0037] As Figure 5 with Figure 6As shown in the figure, the impurity monitoring mechanism further includes a vertical shaft 601. The top of the unlocking rod 504 is rotatably connected to the vertical shaft 601. The vertical shaft 601 is rotatably connected to the rotating disk 505 in a penetrating manner. Four uniformly distributed guiding grooves are formed on the outer wall of the vertical shaft 601. Second elastic limit pins 602 are slidably connected in the four guiding grooves respectively. Four uniformly distributed hemispherical grooves are formed on the inner wall of the rotating disk 505. The four hemispherical grooves are arranged in one-to-one correspondence with the four guiding grooves, and the four hemispherical grooves are used in cooperation with the four second elastic limit pins 602 respectively.

[0038] As Figure 5 shown Figure 6 As shown in the figure, the impurity monitoring mechanism further includes a first push rod 701. The top of the U-shaped rod 501 is fixedly connected to the first push rod 701. The first push rod 701 is located on the left side of the special-shaped frame 502. A second push rod 702 that cooperates with the first push rod 701 is fixedly connected to the outer wall of the rotating disk 505. When the first push rod 701 contacts the second push rod 702, the unlocking rod 504 can slide horizontally.

[0039] As Figure 6 shown in the figure, the impurity monitoring mechanism further includes an L-shaped frame 801. The L-shaped frame 801 is fixedly connected to the rear side of the top of the collection box 204. An elastic wedge block 802 is vertically slidably connected in the L-shaped frame 801. The elastic wedge block 802 is used in cooperation with the four push rods 506.

[0040] As Figure 5 and Figure 7 shown in the figure, the real-time monitoring base station for the water environment of groundwater further includes a cleaning mechanism. The cleaning mechanism includes a top rod 901. The top rod 901 is fixedly connected to the rear side of the bottom of the installation box 207. A roller is rotatably connected to the bottom of the top rod 901 in a penetrating manner. A first cleaning frame 902 is arranged at the rear side of the filter plate 205. A plurality of cylinders are fixedly connected to the front side of the first cleaning frame 902. The plurality of cylinders are used in cooperation with the filter plate 205. A fourth elastic member is arranged between the first cleaning frame 902 and the filter plate 205. The fourth elastic member is an elastic telescopic rod. The roller is used in cooperation with the first cleaning frame 902. When the roller contacts the first cleaning frame 902, the plurality of cylinders of the first cleaning frame 902 can be inserted into the filter holes of the filter plate 205.

[0041] Initially, the two first elastic limiting pins 401 are in a released state, and the two first elastic limiting pins 401 are respectively inserted into the two limiting holes of the filter plate 205, so that the filter plate 205 is restricted to maintain a vertical state, and there is a large gap between the top surface of the collection box 204 and the bottom surface of the installation box 207. As the groundwater flows, the flow plate at the bottom of the collection box 204 is under the action of the groundwater, and the length direction of the flow plate is consistent with the flow direction of the groundwater, thereby making the opening direction of the collection box 204 consistent with the flow direction of the groundwater. It enters the collecting box 204 and passes through the filter plate 205. The filter plate 205 can intercept and collect impurities in the groundwater. At the same time, the groundwater impacts the impeller 208. The impeller 208 is forced to drive the reciprocating screw 202 to rotate. The reciprocating screw 202 drives the collecting box 204 to move vertically back and forth through the V-shaped frame 203, so that the collecting box 204 can move vertically back and forth in the groundwater, which is convenient for the collecting box 204 to collect impurities in groundwater at different depths. During this process, the first sensor 206 monitors the flow velocity of groundwater at different depths.

[0042] Initially, the second elastic member is in a contracted state, both pressing plates 302 are in a horizontal state, the third elastic member is in a released state, there is a gap between the second sensor 303 and the pressing plate 302, and the second push rod 702 is located on the right side of the rotating disk 505. When the collection box 204 moves upward, the collection box 204 drives the sliding shaft 304 to lift upward, and the distance between the sliding shaft 304 and the T-shaped rod 305 gradually shortens until the sliding shaft 304 contacts the lower inclined surface of the corresponding T-shaped rod 305. The T-shaped rod 305 presses against the outer wall of the sliding shaft 304, and the sliding shaft 304 drives the second sensor 303 to move horizontally backward due to the force. Since the elastic force of the third elastic member is greater than that of the second elastic member, the second sensor 303 can drive the cross bar 301 to slide horizontally backward through the third elastic member, and the second elastic member is stretched by the force. The cross bar 301 drives both pressing plates 302 to slide horizontally backward, and the convex shafts of the pressing plates 302 slide along the inclined surfaces of the corresponding V-shaped grooves. The convex shafts drive the corresponding pressing plates 302 to rotate around the connection point of the cross bar 301 until the convex shafts slide to the corners of the V-shaped grooves. At this time, both pressing plates 302 rotate to a vertical state and are respectively attached to the top and bottom inner walls of the collection box 204. The cross bar 301 continues to drive both pressing plates 302 to slide backward. It should be noted that at this time, a part of the impurities in the groundwater has been intercepted on the front side of the filter plate 205. After the cross bar 301 and both pressing plates 302 move and contact the impurities, since the filter plate 205 is restricted by the two first elastic limit pins 401 and cannot rotate at this time, the cross bar 301 and both pressing plates 302 cannot continue to move after contacting the impurities. The sliding shaft 304 continues to drive the second sensor 303 to move, and the second sensor 303 slides relative to the horizontal shaft on the cross bar 301. The third elastic member is compressed by the force, and the second sensor 303 transmits the relative sliding distance between it and the horizontal shaft to the base station body 1. The base station body 1 records the sliding distance of the second sensor 303, thereby monitoring the impurity content in the groundwater. While the sliding shaft 304 slides, it drives the C-shaped rod 501 to slide horizontally backward. The C-shaped rod 501 drives the special-shaped frame 502 and the first push rod 701 to move horizontally. The special-shaped frame 502 drives the push plate 503 to move horizontally until the push plate 503 contacts and presses one of the push rods 506. The push rod 506 is driven by the force to rotate the rotating disk 505 counterclockwise by ninety degrees. When the push rod 506 rotates, it contacts and presses the wedge surface of the elastic wedge block 802. The elastic wedge block 802 is compressed by the force and then contracts. Subsequently, the push rod 506 passes over the elastic wedge block 802 and no longer contacts the elastic wedge block 802. The elastic wedge block 802 is released and slides back to its original position, and the rotating disk 505 drives the other three push rods 506 and the second push rod 702 to revolve around the connection point of the rotating disk 505 and the unlocking rod 504. At the same time, the four hemispherical grooves of the rotating disk 505 respectively press against the four second elastic limit pins 602. The four second elastic limit pins 602 are respectively compressed by the force and slide until the rotating disk 505 rotates ninety degrees, and the four second elastic limit pins 602 are all released and reset.The second push rod 702 is inserted into the four hemispherical grooves of the rotating disk 505 to limit the rotating disk 505. At this time, the second push rod 702 is located at the rear side of the rotating disk 505, thereby completing a monitoring of the impurity content in the groundwater.

[0043] Subsequently, the impeller 208 continues to drive the reciprocating lead screw 202 to rotate. The reciprocating lead screw 202 drives the collection box 204 to descend and reset through the U-shaped frame 203. The collection box 204 drives the sliding shaft 304 to descend. The distance between the sliding shaft 304 and the installation box 207 gradually increases, and the third elastic member gradually releases until the second sensor 303 slides back to its original position. Subsequently, the second elastic member gradually contracts and drives the cross bar 301 to slide back to its original position. During the process of the cross bar 301 sliding back to its original position, the cross bar 301 drives the two pressing plates 302 to slide horizontally. The pressing plates 302 drive the convex shafts thereon to slide along the corresponding V-shaped grooves until the convex shafts slide to the corners of the V-shaped grooves. The convex shafts slide along the inclined surfaces of the V-shaped grooves and drive the pressing plates 302 to rotate and reset with the connection point of the cross bar 301 as the center until the cross bar 301 slides back to its original position and the two pressing plates 302 rotate back to their original positions. At the same time, the sliding shaft 304 drives the special-shaped frame 502 and the first push rod 701 to move back to their original positions through the U-shaped rod 501. The special-shaped frame 502 drives the push plate 503 to move back to its original position. During the process of the push plate 503 moving back to its original position, the front side of the push plate 503 contacts another push rod 506. The push rod 506 presses the push plate 503. The push rod 506 rotates upward with the connection point of the special-shaped frame 502 as the center until the push plate 503 passes over the push rod 506 and no longer contacts the push rod 506. After the push plate 503 is released from the restriction, it rotates back to its original position. The reciprocating lead screw 202 continues to rotate to make the collection box 204 descend and reset, and then the above steps are repeated to monitor the impurity content of the groundwater. By recording and comparing the signals transmitted by the second sensor 303 to the base station body 1 each time, the impurity content in the groundwater can be monitored in batches, so as to know whether the impurities in the groundwater increase or decrease. Until the second push rod 702 rotates to the front side of the rotating disk 505. When the U-shaped rod 501 moves backward again, the U-shaped rod 501 drives the special-shaped frame 502 and the first push rod 701 to move. The special-shaped frame 502 drives the push plate 503 to move. After the first push rod 701 moves, it contacts and presses the second push rod 702. The second push rod 702 is forced to drive the unlocking rod 504 to slide backward through the rotating disk 505. After the unlocking rod 504 slides, the wedge-shaped surface of the unlocking rod 504 contacts and presses the protruding shafts of the two first elastic limit pins 401. The protruding shafts are forced to drive the corresponding first elastic limit pins 401 to lift and slide upward. After the first elastic limit pins 401 slide, they脱离 the limit holes of the filter plate 205. After the filter plate 205 is released from the restriction, it can move. At this time, the two pressing plates 302 rotate to the vertical state again and contact and press the impurities on the front side of the filter plate 205. The impurities transfer the force of the cross bar 301 and the two pressing plates 302 to the filter plate 205. The filter plate 205 rotates with the connection point of the collection box 204 as the center under the force. The first elastic member is forced to contract. When the filter plate 205 rotates, it drives the first cleaning frame 902 to rotate upward with the connection point of the filter plate 205 and the collection box 204 as the center through the fourth elastic member. After the filter plate 205 rotates, the groundwater flushes the impurities on the front side of the filter plate 205 clean.Then, the first cleaning frame 902 contacts the roller of the top rod 901, the filter plate 205 continues to rotate, the roller squeezes the first cleaning frame 902, the fourth elastic member contracts under force, and the first cleaning frame 902 moves to the side close to the filter plate 205, and several cylinders on the first cleaning frame 902 are inserted into the filter holes of the filter plate 205 to squeeze out the impurities in the filter holes, thereby preventing the filter holes of the filter plate 205 from being blocked, and then the impeller 208 continues to drive the reciprocating screw 202 to rotate, and the reciprocating screw 202 drives the collection box 204 to fall downward and reset, and the collection box 204 drives the sliding shaft 304 to fall downward, thereby causing the cross bar 301, The two squeezing plates 302 and the sliding shaft 304 move and reset. After the cross bar 301 and the two squeezing plates 302 are reset, the filter plate 205 is no longer subjected to force, and the first elastic member is released to drive the filter plate 205 to rotate and reset. The filter plate 205 drives the first cleaning frame 902 to rotate and reset through the fourth elastic member. During the rotation of the first cleaning frame 902, the fourth elastic member is gradually released to drive the first cleaning frame 902 to move and reset relative to the filter plate 205, and the bottom ends of the two first elastic limiting pins 401 are in contact with the outer wall of the filter plate 205 until the filter plate 205 is rotated and reset, and the two limiting holes of the filter plate 205 are respectively aligned with the two first elastic limiting pins 401. The two first elastic limiting pins 401 are aligned, the two first elastic limiting pins 401 are released to slide back and are respectively inserted into the two limiting holes of the filter plate 205, so as to limit the filter plate 205. In the process of releasing and sliding the two first elastic limiting pins 401, the two first elastic limiting pins 401 respectively drive the protruding shafts thereon to squeeze the wedge-shaped surface of the unlocking rod 504. The unlocking rod 504 is forced to slide back horizontally and drive the rotating disk 505 and the vertical axis 601 to move and reset. The rotating disk 505 drives the four push rods 506 thereon and the second push rod 702 to move and reset. In this process, the vertical position of the elastic wedge block 802 is The surface contacts and squeezes one of the push rods 506, and the push rod 506 is forced to drive the rotating disk 505 to rotate counterclockwise by 90 degrees. The four hemispherical grooves of the rotating disk 505 squeeze the four second elastic limiting pins 602 respectively, and the four second elastic limiting pins 602 are respectively forced to shrink until the rotating disk 505 rotates 90 degrees. The four second elastic limiting pins 602 are released and reset, and are stuck in the four hemispherical grooves of the rotating disk 505 to limit the rotating disk 505. At this time, the second push rod 702 is located on the left side of the rotating disk 505, thereby preventing the first push rod 701 from contacting the second push rod 702 when it moves next time.

[0044] Example 2

[0045] like Figure 8 and Fig. 9As shown in the figure, the driving mechanism further includes a guiding shaft 1001. The guiding shaft 1001 is symmetrically and fixedly connected to the top of the mounting box 207. Both guiding shafts 1001 are slidably connected to the C-shaped frame 203 in a penetrating manner. The top ends of the two guiding shafts 1001 are commonly fixedly connected to a connecting plate. The connecting plate is fixedly sleeved on the outer wall of the connecting rod 201. An arc-shaped rod 1002 is fixedly connected to the top inner wall of the mounting box 207. A second cleaning frame 1003 is slidably connected to the outer wall of the blade of the impeller 208. A fifth elastic member is arranged between the second cleaning frame 1003 and the outer wall of the blade of the impeller 208. The fifth elastic member is an elastic telescopic rod. A sliding shaft used in cooperation with the arc-shaped rod 1002 is fixedly connected to the top of the second cleaning frame 1003.

[0046] As Fig.10 shown, the real-time monitoring base station for the water environment of groundwater further includes a water level monitoring mechanism. The water level monitoring mechanism includes a sliding frame 1101. The sliding frame 1101 is slidably connected to the outer wall of the connecting rod 201. Air bags 1102 are symmetrically installed on the outer wall of the sliding frame 1101. First connecting rods 1103 are symmetrically rotatably connected to both sides of the sliding frame 1101. A sixth elastic member is arranged between the first connecting rod 1103 and the sliding frame 1101. The sixth elastic member is a torsion spring. Floating balls 1104 are installed at the mutually remote ends of the two first connecting rods 1103. Second connecting rods 1105 are symmetrically hinged to the outer wall of the first connecting rod 1103. A friction strip 1106 is hinged to one end of the second connecting rod 1105. The friction strip 1106 is slidably connected to the sliding frame 1101. The friction strip 1106 is used in cooperation with the connecting rod 201. A third sensor 1107 is installed on the inner wall of the sliding frame 1101. The third sensor 1107 is electrically connected to the base station body 1.

[0047] Due to the long-term impact of groundwater on the impeller 208, impurities or minerals in the groundwater will gradually adsorb on the surface of the impeller 208. During the rotation of the impeller 208, the blades of the impeller 208 drive the second cleaning frame 1003 thereon to revolve around the connection point between the impeller 208 and the mounting box 207 as the center. When one of the second cleaning frames 1003 rotates to the front side, the sliding shaft at the top of the second cleaning frame 1003 contacts the outer arc surface of the arc-shaped rod 1002. As the impeller 208 continues to rotate, the sliding shaft is extruded by the outer arc surface of the arc-shaped rod 1002. The sliding shaft drives the second cleaning frame 1003 to slide along the surface of the corresponding blade to the side away from the axis of the impeller 208 under the force. The fifth elastic member is stressed and extends. When the second cleaning frame 1003 slides, it can scrape off the impurities or minerals on the surface of the blade of the impeller 208, thereby preventing excessive impurities or minerals on the surface of the blade of the impeller 208 from causing a reduction in the rotation efficiency of the impeller 208. Subsequently, the sliding shaft at the top of the second cleaning frame 1003 crosses the arc-shaped rod 1002 and no longer contacts it. The contraction of the fifth elastic member drives the second cleaning frame 1003 to slide back to its original position, thus completing the cleaning of the blade of the impeller 208.

[0048] When the groundwater level is relatively stable, the airbag 1102 is affected by the buoyancy of the groundwater, driving the sliding frame 1101 to always remain near the groundwater level, the sixth elastic member remains in a released state, the two first connecting rods 1103 are in a vertical state relative to the connecting rod 201, and the third sensor 1107 transmits a signal to the base station body 1 according to the relative movement distance between it and the connecting rod 201, thereby recording the groundwater level. When the groundwater level fluctuates violently occasionally, the two floating balls 1104 are affected by the buoyancy and carry The first connecting rod 1103 corresponding to the first connecting rod 1103 rotates, and the first connecting rod 1103 is forced to rotate with the connection point of the sliding frame 1101 as the center of the circle, and the sixth elastic member is forced to shrink. At the same time, the first connecting rod 1103 drives the corresponding second connecting rod 1105 to move. When the floating ball 1104 drives the first connecting rod 1103 to swing upward, the first connecting rod 1103 squeezes the second connecting rod 1105 on its upper side and applies tension to the second connecting rod 1105 on its lower side. The second connecting rod 1105 on the lower side drives the corresponding friction strip 1106 to move away. When the floating ball 1104 drives the first connecting rod 1103 to swing downward, the first connecting rod 1103 is forced to move against the second connecting rod 1103 on the lower side. The connecting rod 1105 is squeezed and a pulling force is applied to the second connecting rod 1105 on its upper side. The second connecting rod 1105 on the upper side drives the corresponding friction strip 1106 to slide to the side away from the connecting rod 201. The second connecting rod 1105 on the lower side drives the corresponding friction strip 1106 to move under the force. After the movement, the friction strip 1106 on the lower side contacts the outer wall of the connecting rod 201 and achieves the same effect as the above steps, thereby making it easier to monitor the liquid level of groundwater and more accurate to monitor the average value of the liquid level of groundwater.
