Mobile water quality on-line monitoring equipment

Abstract

The invention relates to the field of water quality monitoring, in particular to mobile water quality online monitoring equipment which comprises a mounting box, an ups power supply, a signal processing unit and the like. A signal processing unit used for collecting detection signals of the electrode sensors is arranged on the right portion of the rear side of the installation box. And an ups power supply for supplying power is arranged at the left part of the rear side of the mounting box. According to the technical scheme provided by the invention, the floating plate body is fixed in water through cooperation of the insertion rod and the supporting rod, so that the problems that the floating plate is relatively large in swing amplitude due to influence of water flow and wind power in the process that the floating plate is fixed on the shore through a rope to monitor water quality, and the floating plate is relatively small in swing amplitude due to relatively shallow water flow are solved. The problem that the filter screen in the connecting pipe is plugged due to the fact that the filter screen and other structures on the lower side of the floating plate stir water flow to drive silt at the water bottom to float upwards and make the water become turbid and the content of the silt in the water entering the monitoring equipment is large is solved. However, the filter screen in the pipeline can be quickly blocked.

Description

Technical Field

[0001] The present invention relates to the field of water quality monitoring, and in particular to a mobile online water quality monitoring device. Background Art

[0002] Some existing water quality monitoring equipment is divided into two parts, one is the monitoring equipment, and the other is the sampling equipment placed in the water. When the water quality monitoring equipment is in use, the sampling pipe with a floating plate installed is placed in the water, and the floating plate is fixed by a rope, one end of the rope is fixed to the floating plate, and the other end is fixed to the monitoring equipment. The water is pumped into the monitoring equipment through a water supply pump connected to the sampling pipe, and the water quality is detected by the internal sensor. However, in this process, the floating plate fixed by the rope will swing due to the influence of water flow and wind force, resulting in the monitoring equipment being used in shallow water areas near the shore. The pipes and filters installed on the floating plate will contact the mud and sand at the bottom of the water, and then stir the mud and sand, making the water mixed with the mud and sand turbid. The water flow containing mud and sand is pumped into the monitoring equipment through the pipe. Although a filter screen is installed in the pipe, this will cause the filter screen in the pipe to be blocked quickly. Summary of the invention

[0003] In order to overcome the disadvantages that in the use of some existing monitoring equipment, the floating plate fixed by ropes swings due to the water flow and wind, stirring the water flow in the shallow water area near the shore, making the water flow mixed with sediment and becoming turbid, causing the water flow and sediment to enter the monitoring equipment through the pipeline, and although a filter screen is provided inside the pipeline, the sediment will accumulate inside the pipeline, causing the filter screen to be blocked, the present invention provides a mobile water quality online monitoring device.

[0037] Example 1

[0038] like Figure 1-Figure 10As shown, a mobile water quality online monitoring device includes an installation box 1, a UPS power supply 2, a signal processing unit 3 and a water quality detection cabin 4; the installation box 1 is divided into two spaces, front and back, by a partition; the signal processing unit 3 is arranged at the right rear side of the installation box 1; the UPS power supply 2 is arranged at the left rear side of the installation box 1; the water quality detection cabin 4 is arranged at the front side of the installation box 1; the water quality detection cabin 4 contains a water supply pump, a residual chlorine high-precision electrode sensor, a pH high-precision electrode sensor, a conductivity high-precision electrode sensor, a chromaticity high-precision electrode sensor, and a turbidity high-precision electrode sensor; the water quality detection cabin 4 is provided with a water supply pump;

[0039] It also includes a floating plate body 5, a plug rod 6, a water inlet head 8, a first take-up box 101, a connecting pipe 102, a connecting plate 104, a first elastic member 105 and a block 106; the plug rod 6 is slidably connected to the floating plate body 5; the floating plate body 5 is provided with a water inlet head 8; an electric reel is installed in the installation box 1, and a connecting pipe 102 is reeled on the electric reel; one end of the connecting pipe 102 is connected to the water supply pump, and the other end is connected to the water inlet head 8; a slide groove 6001 is provided on the plug rod 6; a sliding connection part 5 is provided on the floating plate body 5 002; the sliding connection part 5002 slides inside the slide groove 2 6001; a slot 6003 is provided at the upper end of the insertion rod 6; a slide groove 1 5001 is provided on the floating plate body 5; there are four first elastic members 105 in a circular array on the floating plate body 5, and the first elastic members 105 are spring rods; the number of the slide groove 1 5001 is the same as the number of the first elastic members 105; a block 106 is fixedly connected to the output end of each first elastic member 105; each block 106 is located in an adjacent slide groove 1 5001; the side surface of the block 106 is arc-shaped.

[0040] The sliding connection part 5002 is wedge-shaped, and the lower side of the second slide groove 6001 is inclined from top to bottom. By sliding the sliding connection part 5002 up and down along the second slide groove 6001, impurities inside the second slide groove 6001 can be scraped off to prevent the floating plate body 5 from being stuck when sliding up and down.

[0041] It also includes a connecting rod 103, a first clamping ball 201, a limit plate 202 and a first fixed plate 203; the upper end of the insertion rod 6 is slidably connected to the connecting rod 103; a sliding groove 3 6002 is provided at the upper end of the insertion rod 6; the lower side of the connecting rod 103 penetrates into the sliding groove 3 6002; the lower side of the connecting rod 103 is fixedly connected to the first fixed plate 203; the first clamping ball 201 is provided on the first fixed plate 203; the first clamping ball 201 is connected to the first fixed plate 203 through a spring; a plurality of clamping holes 6005 are provided in the sliding groove 3 6002; the number of the clamping holes 6005 is the same as the number of the first clamping ball 201; four limit plates 202 are provided on the lower side of the first fixed plate 203; each limit plate 202 is provided with a limit groove 1 20201.

[0042] It also includes a support rod 7, a second elastic member 204 and a second locking ball 205; four support rods 7 are rotatably connected to the lower side of the insertion rod 6; a second elastic member 204 is fixedly connected to the fixed end of the support rod 7, and the second elastic member 204 is a spring; the other end of the second elastic member 204 is fixedly connected to the movable end of the support rod 7; a second locking ball 205 is provided at the movable end of the support rod 7; the second locking ball 205 is connected to the movable end of the support rod 7 through a spring; a plurality of limiting grooves 7001 arranged in a straight line along the axis are provided inside the fixed end of the support rod 7; the limiting grooves 7001 and the second locking balls 205 are on the same straight line.

[0043] When the present invention is used, a worker carries the mobile water quality online monitoring device to the water area to be monitored, and then fixes the installation box 1 on the shore. The worker moves the rod 6 to the pre-selected monitoring position, and then inserts the rod 6 into the water. The worker observes whether the rod 6 is in a horizontal state through the level meter at the upper end of the rod 6. When the worker adjusts the rod 6 to a horizontal state, the insertion of the rod 6 is completed. Then, the worker draws out the connecting pipe 102 inside the installation box 1, and installs the starting end of the connecting pipe 102 on the floating plate body 5, so that the connecting pipe 1 02 is connected with the water inlet head 8, and the water supply pump in the water quality detection cabin 4 is started to pump water, so that the water flows into the water quality detection cabin 4 through the connecting pipe 102 and the water inlet head 8, and then the water quality is detected by the residual chlorine high-precision electrode sensor, pH high-precision electrode sensor, conductivity high-precision electrode sensor, chromaticity high-precision electrode sensor, turbidity high-precision electrode sensor and the like in the water quality detection cabin 4, and then the detected information is transmitted to the signal processing unit 3 through the sensor, and then transmitted to the display screen on the installation box 1 through the signal processing unit 3 for viewing by the monitoring personnel.

[0044] When the present invention is in use, since the monitored water level outside will change, the insertion rod 6 is slidably connected to the floating plate body 5, so that the floating plate body 5 can rise and fall on the insertion rod 6 as the water level changes. The floating plate body 5 drives the water inlet head 8 to move up and down, so that the water inlet head 8 always floats on the water surface, avoiding the water inlet head 8 staying at the bottom of the water for a long time, and sucking the mud and sand in the water into the connecting pipe 102, causing the connecting pipe 102 to be blocked.

[0045] Furthermore, since the floating plate body 5 has buoyancy and is slidably connected to the insertion rod 6, when the worker inserts the insertion rod 6 into the water, the floating plate body 5 is initially located at the lower side of the insertion rod 6, and during the insertion of the insertion rod 6, the floating plate body 5 always floats on the water surface, affecting the worker's line of sight. Secondly, the buoyancy of the floating plate body 5 will generate resistance during the insertion of the insertion rod 6, affecting the insertion of the insertion rod 6. Therefore, a first elastic member 105, a clamping block 106, a first clamping ball 201, a limiting plate 202 and a first fixing plate 203 are provided; before inserting the insertion rod 6 into the water, the worker first moves the floating plate body 5 to the position as shown in the figure. Figure 1In the state shown, the arc-shaped block 106 is squeezed during this process. When the floating plate body 5 moves along the second slide groove 6001 to connect the slide groove 1 5001 with the slot 6003, the upper arc surface of the block 106 first contacts the slot 6003. At the same time, the first elastic member 105 has a certain elastic force in the initial state, but is limited by the second slide groove 6001 and cannot pop out. When the slide groove 1 5001 is connected with the slot 6003, the restriction of the second slide groove 6001 on the first elastic member 105 is released, and the block 106 is driven to pop out into the slot 6003 by the elastic force of the first elastic member 105 itself, thereby fixing the floating plate body 5 on the upper side of the insertion rod 6, and the first elastic member 105 is fixed on the upper side of the insertion rod 6. The initial state is limited by the second slide groove 6001 to be a contracted state. When the first slide groove 5001 is connected with the clamping groove 6003, the elastic force of the first elastic member 105 moving toward the center of the plug rod 6 drives the clamping block 106 to move toward the center of the plug rod 6, so that the clamping block 106 enters the clamping groove 6003. When the worker inserts the plug rod 6 into the water, the floating plate body 5 is not easy to block the line of sight, so as to avoid affecting the insertion of the plug rod 6. At the same time, the floating plate body 5 located on the upper side can be used as a force plate to facilitate the worker to press the plug rod 6 downward. At this time, in order to prevent the clamping block 106 from slipping during the pressing process, the worker holds the connecting rod 103 and presses downward, and the connecting rod 103 drives the limiting plate 202 to move downward to clamp the clamping block 106, which is as shown in the figure. Figure 6 In the state shown, during this process, when the first locking ball 201 located on the first fixed plate 203 and squeezed by the slide groove three 6002 reaches the position corresponding to the locking hole 6005 on the slide groove three 6002, the first locking ball 201 is driven to pop outward by the elastic force of the spring itself, so that the first locking ball 201 slides into the locking hole 6005, thereby locking the locking block 106 and preventing the floating plate body 5 from acting as a force plate and the locking block 106 from slipping off when the worker presses the floating plate body 5.

[0046] It should be noted that after the floating plate body 5 is locked by the block 106 and the limit plate 202, when it is needed to be unlocked, the worker holds the connecting rod 103 with one hand and pulls it upward, while the worker presses the floating plate body 5 with the other hand, and drives the limit plate 202 and other parts to move upward through the connecting rod 103, forming a Figure 7 In the state shown, the limiting plate 202 is separated from the blocking block 106 , and then the worker presses the floating plate body 5 downward to make the blocking block 106 disengage from the blocking groove 6003 .

[0047] Furthermore, since the soil at the bottom of the water is relatively loose, especially when the rod 6 is inserted in the same position for a long time, the impact of the water flow will cause the soil to become looser, resulting in the rod 6 being skewed, etc., thereby affecting the stability of the rod 6 and its parts. Therefore, a support rod 7 is designed. Before the rod 6 is inserted into the water, the support rod 7 is pulled outward by a worker to form a Figure 3In the state shown, the worker then adjusts the length of the support rod 7, inserts the opened support rod 7 into the water together with the insertion rod 6, and increases the stability of the insertion rod 6 through the support rod 7.

[0048] It should be noted that due to the different heights of the bottom of the water, when the float body 5 is located at the lowest end of the slide groove 6001, the water inlet head 8 is still higher than the connection between the support rod 7 and the insertion rod 6, resulting in the water inlet head 8 being unable to approach the bottom of the water when the monitoring equipment needs to monitor the water quality conditions near the bottom of the water. Therefore, when the water inlet head 8 needs to move downward to approach the bottom of the water, the first wire box 101 can be used to release the line to move the water inlet head 8 downward to extract water near the bottom of the water. The pressure sensor provided at the bottom of the water inlet head 8 can be used to determine whether the water inlet head 8 has reached the bottom of the water, thereby preventing the first wire box 101 from releasing the line too long, causing the water inlet head 8 to tip over at the bottom of the water, causing mud and sand to enter the inside of the water inlet head 8.

[0049] The above-mentioned working process is the method of using the present invention for shallow water area detection. The float body 5 is fixed in the water by the insertion rod 6 and the support rod 7. This solves the problem that in the existing process of fixing the float to the shore by ropes to monitor water quality, the float swings greatly due to the influence of water flow and wind, thus affecting the detection.

[0050] It should be noted that the present invention needs to perform multi-point detection when in use, so that the present invention needs to be moved frequently. In this case, a fixed power supply is not convenient to use. Therefore, the present invention has a built-in UPS power supply 2. When the present invention performs multi-point detection, the UPS power supply 2 can be started to power the device, thereby providing power to the present invention when a fixed power supply is not convenient to use.

[0051] Example 2

[0052] On the basis of Example 1, Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, a connecting groove is provided on the lower side of the movable end of the support rod 7; a counterweight block can be installed on the lower side of the support rod 7 through the connecting groove, so as to facilitate fixing the insertion rod 6 in the pond constructed with cement on the lower side.

[0053] When the monitoring location pre-selected by the present invention is a pond with a bottom smoothed with cement, the insertion rod 6 cannot be inserted into the bottom of the water to fix the float body 5. Therefore, when the present invention is in use, a counterweight block can be installed on the telescopic part on the lower side of the support rod 7. The equipment is fixed in the water through the counterweight block, and the insertion rod 6 is kept in a vertical state, thereby improving the applicability of the present invention in different environments.

[0056] It also includes a limiter 310 and a third rope 311; the limiter 310 is fixedly connected to the conical fixture 303; a socket 30301 is provided on the conical fixture 303; a limit hole is provided on the limiter 310; the socket 30301 is connected to the limit hole on the limiter 310; the third rope 311 is plugged into the limiter 310; the other end of the third rope 311 is fixedly connected to the water inlet head 8.

[0057] It also includes a third fixing plate 401 and a separation block 402; the third fixing plate 401 is fixedly connected to the inside of the cavity 6004; the third fixing plate 401 is located at the upper right of the second fixing plate 302; a mounting groove 40101 is opened on the third fixing plate 401; the first rope 308 passes through the mounting groove 40101; the separation block 402 is fixedly connected to the left side of the mounting groove 40101; the separation block 402 is circular; the separation block 402 is located in the embedded groove 30801.

[0058] When the present invention monitors the water quality in a deep water area far from the shore, such as the center of a lake, the water body is deep and the length of the rod 6 is insufficient. The rod 6 cannot be inserted into the water bottom when operated manually. Therefore, after the worker takes a boat to move the rod 6 and the floating board body 5 to the water surface of the pre-selected monitoring point, the rod 6 and the floating board body 5 are placed in the water, and the rod 6 and the floating board body 5 are connected to the installation box 1 by an external rope as a preliminary fixation, and then the second take-up box 301 is controlled to release the first rope 308 and the second rope 309, so that the conical fixture 303 moves downward under the action of its own gravity, but the third elastic member 306 is as shown in Fig.13 In the state shown, the third elastic member 306 is restricted by the first rope 308 and the second rope 309 and cannot be retracted. Therefore, when the conical fixture 303 reaches the bottom of the water, the conical fixture 303 cannot move downward, but the second rope 309 continues to move downward. At this time, the second rope 309 contracts by its own tightening force, and the conical fixture 303 is in a state shown in FIG. Fig.15 In the state shown in FIG. 1 , the first linear drive member 305 is squeezed and expanded outward, driving the plug plate 304 to expand outward, as shown in FIG. Fig.15 In the state shown, the worker pulls the rod 6 and drives the rod 6 and other parts through the boat to continue to move toward the monitoring point. The rod 6 is fixed in the deep water area by the principle of placing an anchor, so as to avoid the situation where the rope is too long when fixing the floating board body 5, resulting in a large range of movement of the floating board body 5, thereby reducing the accuracy of water quality monitoring.

[0059] It should be noted that the first rope 308 and the second rope 309 are released through the second wire box 301. During the downward movement of the conical fixture 303, the first rope 308 and the second rope 309 pass through the second fixing plate 302, and the second rope 309 is squeezed by the squeezing block 307 so that the second rope 309 passes into the embedding groove 30801, so that the first rope 308 wraps the second rope 309 inside to form a rope, thereby reducing the possibility of the rope being hooked by impurities in the water.

[0060] Furthermore, when the rod 6 needs to be taken out from the deep water area, the conical fixture 303 needs to be retracted first. However, due to the principle of using the anchor, the conical fixture 303 is in the process of rising. Fig.15 As shown in the state, the conical fixture 303 may be stuck by debris during the rising process. Therefore, before the present invention is lifted upward, the second rope 309 is pulled by the second take-up box 301 on the left side of the cavity 6004. The second rope 309 slides relatively in the first rope 308, driving the telescopic end of the third elastic member 306 to move upward, further driving the first linear drive member 305 to be retracted, and the plug plate 304 is retracted by the first linear drive member 305, so that the conical fixture 303 is as shown in the state shown in the state. Fig.11In the state shown, the first rope 308 and the second rope 309 are synchronously reeled in by the second take-up box 301 to retract the conical fixture 303, so as to prevent the conical fixture 303 from being stuck by impurities in the water when the first rope 308 and the second rope 309 drive the conical fixture 303 to move upward in the water.

[0061] It should be noted that when the second rope 309 is pulled through the second wire box 301 on the left side of the cavity 6004, since the weight of the conical fixture 303 itself is greater than the friction between the first rope 308 and the second rope 309, the first rope 308 remains vertical when the second rope 309 moves upward alone.

[0062] It should be noted that before the first rope 308 passes through the through groove 30201, the embedding groove 30801 is first expanded by the separation block 402 to prevent the first rope 308 from being squeezed after being rolled up, causing the embedding groove 30801 to deform, making it difficult for the second rope 309 to enter the embedding groove 30801. At the same time, the embedding groove 30801 moving upward from the water can be cleaned by the separation block 402.

[0063] Example 4

[0064] On the basis of Examples 1, 2 and 3, Figure 1 , Figure 16-Figure 17 As shown, it also includes a scraper 501, a gear ring 503, a gear 504 and a motor 505; the motor 505 is fixedly connected to the lower side of the connecting plate 104; the gear 504 is fixedly connected to the output end of the motor 505; the gear ring 503 is rotatably connected to the connecting plate 104; the gear ring 503 is meshed with the gear 504; the scraper 501 is fixedly connected to the gear ring 503.

[0065] It also includes a cutter 502 ; a plurality of cutters 502 are arranged on the scraper 501 .

[0066] During use of the present invention, while water is pumped by the water supply pump, impurities in the water, such as water plants, etc., will accumulate on the outside of the water inlet head 8, blocking the water inlet on the surface of the water inlet head 8, affecting the water inlet efficiency of the water inlet head 8, and further affecting the equipment monitoring efficiency. Therefore, during use of the present invention, the motor 505 drives the gear 504 to rotate, and the gear 504 drives the gear ring 503 meshing with it to rotate, and the gear ring 503 drives the scraper 501 to rotate along the surface of the water inlet head 8 to scrape off the debris on the surface of the water inlet head 8 to ensure the water inlet efficiency of the water inlet head 8. At the same time, the scraper 501 is inclined outward, which can guide the debris away from the surface of the water inlet head 8, thereby increasing the cleaning effect on the surface of the water inlet head 8. At the same time, a cutter 502 is provided on the surface of the scraper 501, which can cut off the water plants and other debris entangled on the surface of the water inlet head 8, thereby further enhancing the cleaning effect on the water inlet head 8.
