Description

Technical Field

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

[0002] The culvert drainage system is an important infrastructure for urban underground space, used to convey domestic water, surface rainwater and industrial sewage. The water quality monitoring of the culvert drainage system is an important part of the comprehensive treatment of the urban water environment. In the culvert drainage system, existing water quality monitoring devices are usually fixedly installed on the inner wall of the drainage pipe. However, the water level in the drainage pipe often changes. If the installation position is too high, it cannot be monitored when the water level is lower than the monitoring device; if the installation position is too low, sediment is likely to accumulate and cover the monitoring device, affecting the monitoring effect. At the same time, when the water flow velocity in the drainage pipe is fast, continuously impacting the monitoring device immersed in the water is likely to cause damage to its structural strength. Summary of the Invention

[0003] In order to overcome the shortcomings that for fixed water quality monitoring devices, when the water level is lower than the installation position, monitoring cannot be carried out, when the installation position is set low, sediment accumulation in the drainage pipe is likely to cover the monitoring device, affecting the monitoring effect, and the continuous impact of the water flow on the monitoring device immersed in the water is likely to cause damage to its structural strength, the present invention provides a water quality monitoring device with data transmission.

[0004] Technical Solution: A water quality monitoring device with data transmission includes an installation rod and a detector; the top of the installation rod is fixedly connected with an installation plate; threaded holes are opened on the installation plate; the detector is slidably connected to the installation rod; it further includes a monitoring component, an electric valve, a water pump, a support rod, an electric rotating shaft, a water diversion plate and a moving component; a cavity is opened in the detector; a connecting sleeve is installed in the detector; the connecting sleeve is sleeved on the installation rod; a partition is fixedly connected in the detector; a monitoring component for diversely monitoring the water quality is installed below the partition; an electric valve is installed on the top of the detector; the electric valve communicates the cavity with the outside of the detector; a water pump is installed on the partition; the water inlet of the water pump is communicated with the water area to be measured through a water inlet pipe; the water outlet of the water pump is communicated with the cavity; two support rods are rotatably connected to the middle of the detector, and a sealing ring is provided at the connection; two electric rotating shafts are installed in the detector; each electric rotating shaft is fixedly connected to a support rod; a water diversion plate is installed on each support rod; a moving component is connected in the detector.

[0005] In addition, particularly preferably, the monitoring component includes: a flow velocity monitoring head, a water quality monitoring head and a wireless data transmitter, and each monitoring head extends downward out of the detector.

[0006] In addition, it is particularly preferred that the moving component includes: an installation box and a moving wheel; the installation box is installed in the middle of the connecting sleeve; several moving wheels are installed in the installation box; a driving motor is installed in the installation box; the output shaft of the driving motor is connected to a moving wheel, making it a driving wheel, and the remaining moving wheels are driven wheels.

[0007] Furthermore, it is particularly preferred that the moving wheels are rubber wheels.

[0008] In addition, it is particularly preferred that a plurality of blades are fixedly connected to the top and bottom of the connecting sleeve in a circular array.

[0009] In addition, it is particularly preferred that the water-facing side of the support rod is curved.

[0010] In addition, it is particularly preferred that a limiting ball head is fixedly connected to the bottom of the mounting rod.

[0011] In addition, it is particularly preferred that a rubber pad is provided on the top of the detector.

[0012] In addition, it is particularly preferred that a filter screen is provided at the inlet of the water inlet pipe connected to the water inlet.

[0013] In addition, it is particularly preferred that the ends of the support rod and the water guide plate are both provided with a rubber layer.

[0014] The present invention has the following advantages: the present invention realizes that the detector floats on the water surface and moves up and down in real time according to the change of water level, thereby ensuring continuous monitoring of water quality. At the same time, most of the detector is located above the water surface, avoiding damage to the detector structure caused by excessively fast water flow and continuous impact. The position restriction formed between the mounting rod and the detector prevents the detector from shaking due to the impact of water flow, which affects the monitoring effect. The water in the drainage pipe is pumped into the cavity through the water pump, so that it sinks into the water. The moving component is used to limit the downward movement of the detector, and the water level at different depths is monitored. The monitoring range is wide and the practicality is strong. By rotating the support rod and the water guide plate, the strips of debris accumulated on the water-facing surface of the detector are pushed downward over the bottom of the installation rod and carried away by the water flow in the drainage pipe, thereby preventing a large amount of strips of debris from accumulating on the water-facing surface of the detector for a long time, interfering with the monitoring effect of the monitoring components in the detector, and preventing the debris from increasing the water-facing area of the detector and the impact force of the water flow it receives, thereby affecting the structural strength of the detector.

Detailed implementation manners

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] The monitoring components include: a flow rate monitoring head 204, a water quality monitoring head 205 and a wireless data transmitter 206. Each monitoring head extends downwardly out of the detector 2; a battery is installed in the detector 2 to power the internal electric components.

[0020] The moving assembly includes: an installation box 5 and a moving wheel 6; the installation box 5 is installed in the middle of the connecting sleeve 202; at least two moving wheels 6 are installed in the installation box 5; a drive motor 601 is installed in the installation box 5; the output shaft of the drive motor 601 is connected to one moving wheel 6, making it a driving wheel, and the remaining moving wheels 6 serve as driven wheels.

[0021] The moving wheel 6 is a rubber wheel to increase the static friction between it and the mounting rod 1 and improve the locking and limiting effect.

[0022] At least six blades 207 are fixedly connected to the top and bottom of the connecting sleeve 202 in a circular array. When the detector 2 moves up or down along the mounting rod 1, the blades 207 cut the attachments on the surface of the mounting rod 1 and remove them.

[0023] The water-facing side of the support rod 7 is curved; the curved water-facing surface of the support rod 7 guides debris in the water flow away, preventing the debris from being intercepted by the support rod 7 and accumulating on the water-facing surface of the support rod 7.

[0024] A limiting ball head is welded at the bottom of the mounting rod 1 to prevent the detector 2 from being separated from the mounting rod 1 when it sinks into water.

[0025] A rubber pad is provided on the top of the detector 2 to cushion the detector 2 and prevent the detector 2 from hitting the mounting plate 101 due to rapid floating and damaging the detector 2.

[0026] A filter screen is provided at the inlet of the water inlet pipe connected to the water inlet 401; it is used to filter impurities in the water flow to prevent them from entering the detector 2, blocking the water path and damaging the water pump 4.

[0027] The steps to install the present invention and conduct water quality monitoring are as follows: As Figure 2 shown, an installation hole is opened on the upper side of the drainage pipe. The battery in the detector 2 is fully charged to supply power to the electrical components. The mounting plate 101 is fixed to the drainage pipe through expansion screws. The mounting rod 1 is arranged vertically downward. The detector 2 is sleeved on the mounting rod 1. In the initial state, the cavity 201 is in an emptied state, so that the detector 2 can float on the water surface. The lower side of the detector 2 is immersed in the water. Each monitoring head of the monitoring component extending downward from the detector 2 monitors the water quality in real time. The obtained monitoring data is transmitted to the user's remote terminal through the wireless data transmitter 206; when the water level rises or falls, the detector 2 floating on the water surface slides up or down along the mounting rod 1.

[0028] When it is necessary to monitor the water quality at different depths, it is necessary to sink the detector 2 into the water. The specific steps are as follows: Control the water pump 4 to work. The water inlet 401 sucks the external water flow into the water pump 4, and then pumps it into the cavity 201 through the water outlet 402. At the same time, control the electric valve 3 to open to discharge the air in the cavity 201. After the liquid level sensor detects that the water volume in the cavity 201 exceeds half of the height (the subsequent judgment of discharging the water volume in the cavity 201 is also based on this principle), the electric valve 3 is closed. As the cavity 201 is gradually filled with water flow, the remaining air will be compressed in the cavity 201. The self-weight of the detector 2 reaches the maximum and it will slide down along the mounting rod 1 and sink into the water. During this process, the driving motor 601 is powered off and the moving wheel 6 is in a free rolling state. The moving wheel 6 rolls along the outer surface of the mounting rod 1 following the descending detector 2. After the detector 2 sinks into the water, power on the driving motor 601 to lock the moving wheel 6 so that it cannot roll along the mounting rod 1, thereby enabling the detector 2 to maintain its current height and thus monitor the water quality at a specific depth.

[0029] When the sunken detector 2 needs to float, control the water pump 4 to work in reverse. The water in the cavity 201 is sucked in through the water outlet 402 and discharged from the detector 2 through the water inlet 401 to reduce the self-weight of the detector 2. The compressed air in the cavity 201 is released again, enabling the detector 2 to regain its floating ability. When the water volume in the cavity 201 is emptied, the top of the detector 2 will emerge from the water surface. Then control the electric valve 3 to open and the water pump 4 to keep working to re-inhale the external air into the cavity 201 through the electric valve 3, so that the detector 2 is in the best floating state. Then the electric valve 3 is closed and the water pump 4 stops working.

[0030] With Figure 2For reference, when the detector 2 is located in the water for water quality monitoring, the support rod 7 and the water diversion plate 9 are in a horizontal state. Once every 24 hours, the water pump 4 draws water into the cavity 201, causing the detector 2 to sink to the bottom of the mounting rod 1. The electric shaft 8 is then controlled to drive the support rod 7 and the water diversion plate 9 to rotate 360 degrees clockwise. The strip-shaped debris accumulated on the water-facing surface of the detector 2 is pushed downward by the support rod 7 and the water diversion plate 9, removed from the water-facing surface of the detector 2, and passed over the bottom of the mounting rod 1 and carried away by the water flow in the drainage pipe. After the operation is completed, the water volume in the cavity 201 is adjusted by the water pump 4, so that the detector 2 rises to the original monitoring height through buoyancy, and the support rod 7 and the water diversion plate 9 return to a horizontal state.

[0031] When the detector 2 floats on the water surface to monitor the water quality, the electric shaft 8 is controlled to drive the support rod 7 and the water diversion plate 9 to rotate counterclockwise, so that the support rod 7 and the bottom surface of the water diversion plate 9 form an acute angle with the water surface. When the water level of the drainage pipe rises rapidly in a short period of time, the water flow will impact the inclined water diversion plate 9, forming a lift on it, and the water diversion plate 9 drives the detector 2 in the floating state to rise rapidly.

[0032] It should be noted that users need to regularly check the present invention to see if it is working properly, and replace the battery during the inspection to ensure that the battery is sufficient so that the monitoring work can continue.

[0033] According to the above steps, we know that the present invention has the following effects: In culvert drainage systems, existing water quality monitoring equipment is usually fixedly installed on the inner wall of the drainage pipe, and the water level in the drainage pipe often changes. When the water level is lower than the installation position, monitoring cannot be carried out; when the installation position is low, the accumulation of sediment in the drainage pipe is easy to cover the monitoring equipment, affecting the monitoring effect. At the same time, when the water flow rate in the drainage pipe is fast, it continuously impacts the monitoring equipment, which is easy to damage its structural strength. Therefore, the detector 2 of the present invention floats on the water surface and moves up and down in real time according to the water level changes to ensure continuous monitoring of the water quality. At the same time, most of the detector 2 is located above the water surface to avoid damage to the structure of the detector 2 due to the fast water flow rate and continuous impact. A position restriction is formed between the mounting rod 1 and the detector 2 to prevent the detector 2 from shaking due to the impact of the water flow, which affects the monitoring effect.

[0034] When the water level is low and the flow rate is slow, water is pumped into the cavity 201 through the water pump 4, increasing the weight of the detector 2 so that the detector 2 sinks into the water. The moving component is used to limit the downward movement height of the detector 2, and the water levels at different depths are monitored. The monitoring range is wide and the practicability is strong.

[0035] When the detector 2 is located in water for water quality monitoring, strip-shaped debris in the water flow is likely to accumulate on the water-facing surface of the detector 2. When too much debris accumulates, it is likely to interfere with the monitoring effect, and too much debris increases the water-facing area of the detector 2, increasing the impact force of the water flow on the detector 2. Even if the water flow is slow, the long-term effect may still affect the structural strength of the detector 2, and then the detector 2 sinks to the bottom of the installation rod 1. Cooperating with the support rod 7 and the water diversion plate 9 to rotate, the strip-shaped debris accumulated on the water-facing surface of the detector 2 is pushed downward to cross the bottom of the installation rod 1 and is carried away by the water flow in the drainage pipe, avoiding the long-term accumulation of a large amount of strip-shaped debris on the water-facing surface of the detector 2, interfering with the monitoring effect of the monitoring components in the detector 2, and the debris increasing the water-facing area and the impact force of the water flow on the detector 2, affecting the structural strength of the detector 2.

[0036] In addition, when the detector 2 floats on the water surface, an acute angle is formed between the bottom surfaces of the support rod 7 and the water diversion plate 9 and the water surface. When the water level in the drainage pipe rises rapidly in a short time, the water flow will impact the inclined water diversion plate 9 and form a lifting force on it. The water diversion plate 9 drives the floating detector 2 to rise rapidly, avoiding the detector 2 being temporarily submerged due to the sudden rise of the water level.

[0037] It should be noted that the installation rod 1 is cylindrical. The water flow impacts its cylindrical surface, and the pressure is dispersed to both sides. The impact of the water flow on the installation rod 1 is relatively small.

[0038] The additional technical effects of the present invention are as follows: As Figure 4 and Figure 5 shown, the detector 2 is regularly driven to move up or down along the installation rod 1 through the moving wheel 6. The blades 207 at the top and bottom of the connecting sleeve 202 are closely attached to the installation rod 1, cutting off the attachments on the surface of the installation rod 1 and removing them by being carried away by the water flow, avoiding affecting the floating movement of the detector 2.

[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 2 , Figure 6 and Figure 7 shown, rubber layers are provided at the ends of both the support rod 7 and the water diversion plate 9; improving the fitting degree between the support rod 7 and the water diversion plate 9 and the inner wall of the pipe, enhancing the support stability; a pressure sensor is provided at the end of the support rod 7.

[0040] The operation steps of using this embodiment are as follows: When the water flow velocity in the drainage pipe is detected to be extremely fast through the flow velocity monitoring head 204, the water volume in the cavity 201 is emptied through the water pump 4, so that the cavity 201 is in an emptied state, and the detector 2 is in a floating state. As the water level rises, the detector 2 moves towards the top of the installation rod 1, and the electric rotating shaft 8 is controlled to drive the support rod 7 and the water diversion plate 9 to be in a Figure 6As shown, in the state where the end is tilted upward, when the detector 2 approaches the top of the mounting rod 1, the inclined support rod 7 and the water diversion plate 9 will contact the inner wall of the top of the drainage pipe. The rubber layer at the end fits the inner top wall of the drainage pipe to support the detector 2. At the same time, when the pressure sensor at the end of the support rod 7 detects contact with the top inner wall, the driving motor 601 is controlled to be powered on, and the moving wheel 6 locks the detector 2 at the current height position of the mounting rod 1. Thus, a triangular support is formed by the detector 2, the support rod 7, the water diversion plate 9, and the inner top wall of the drainage pipe.

[0041] According to the above steps, we can see that the present invention also has the following effects: The water flow velocity in the drainage pipe is extremely fast (indicating a large amount of water and a high water level in the drainage pipe). At this time, the detector 2 floats to the top of the mounting rod 1 following the water level change and is close to the fixed position of the mounting rod 1, reducing the pressure on the middle and lower parts of the mounting rod 1 caused by the detector 2 being impacted by the water flow, and avoiding deformation of the mounting rod 1 due to excessive force. At the same time, the support rod 7 and the water diversion plate 9 contact the inner top wall of the drainage pipe to reinforce the detector 2 and increase the stability of the detector 2 in the high-speed water flow, ensuring the structural strength of the detector 2.

[0042] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
