Technical Field
[0001] The present invention relates to the technical field of water quality detection, and in particular to a remote fixed-point water quality detection device. Background Art
[0002] Water quality testing is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations and changing trends of various pollutants, and evaluating the water quality status. The monitoring scope is very wide. In addition, various water bodies are mostly transported by water pipelines. At present, when monitoring the water quality of the pipeline, it is necessary to set up sample collection points, or install various sampling equipment and testing equipment in the valve well. The construction is complicated and increases the construction cost. In order to save costs, sample collection points are usually only set up at nearby locations such as water sources, water plant outlets, pipe network terminals, and water supply points. For distant places, sampling is difficult and special personnel need to drive to collect samples. After sampling, they need to go to the laboratory for testing, resulting in inadequate supervision and detection of the entire water supply system.
[0003] In order to overcome the above problems, in order to overcome the difficulty of remote sampling, the prior art often uses sensors installed on water pipes for detection and then transmits data to the cloud or processing center; however, there is still a problem, that is, small sensors need to be powered and wires need to be pulled to meet the requirements, which makes the installation cost high, especially in sparsely populated areas, where power supply is more difficult; and the surface of the sensor's detection head will be covered with scale and fail during long-term use, and still requires periodic maintenance. Therefore, there is a need for a remote fixed-point water quality detection device that does not require additional power supply and can reduce the number of maintenance times, thereby reducing the cost of use.

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.
[0029] Please refer to Figure 1 , a remote fixed-point water quality detection device, used for water quality detection of water in a water delivery pipeline 1, the remote fixed-point water quality detection device comprises a detection component 2 and a descaling component 3;
[0030] The detection assembly 2 includes an outer shell 21, a detector 22, a controller 23, a battery 24, a communicator 25 and a hydroelectric generator 26; the outer shell 21 includes a channel 211 and a sealed chamber 212, the detector 22 includes a detection body and a detection head 221, the detection body, the controller 23, the battery 24, and the communicator 25 are arranged in the sealed chamber 212, and the detection head 221 and the hydroelectric generator 26 are arranged in the channel 211; a first electromagnetic valve 27 is arranged at one end of the channel 211, and the first electromagnetic valve 27 is connected to the water supply pipeline 1; the detection head 221 controls the communicator 25 to transmit the detected water body information through the detection body through the controller 23 for remote data transmission;
[0031] The descaling assembly 3 includes a first three-way valve 31, a sealing cylinder 32, a piston 33, a water tank 34, a hard water pipe 35 and a second three-way valve 36. One end of the sealing cylinder 32 is connected to the other end of the channel 211 through the first three-way valve 31, and the other end of the sealing cylinder 32 is connected to the water tank 34. The initial position of the piston 33 is located in the sealing cylinder 32 close to the first three-way valve 31; the water tank 34 is suspended, and a breathable valve 38 is arranged on the top of the water tank. The second three-way valve 36 is arranged at the bottom of the water tank 34, and the first three-way valve 31 and the second three-way valve 36 are connected; the second three-way valve 36 is connected to the outside through the hard water pipe 35, and the hard water pipe 35 is arranged downward; the water tank 34 is connected to the water supply pipeline 1 through the second electromagnetic valve 37; the controller 23 is electrically connected to the detector 22, the battery 24, the communicator 25, the first electromagnetic valve 27, the second electromagnetic valve 37, the first three-way valve 31, the second three-way valve 36, and the breathable valve 38 respectively;
[0032] When the remote fixed-point water quality detection device is descaling, the controller 23 determines whether there is enough water stored in the water tank 34. If so, descaling is performed. Otherwise, the controller 23 stores water until the water level in the water tank 34 is more than 90% of the volume and then descaling is performed. The descaling work includes: the controller 23 controls the first solenoid valve 27 and the second solenoid valve 37 to be closed, the first three-way valve 31 and the sealing tube 32 are connected, the air valve is opened, the second three-way valve 36 is connected to the hard water pipe 35 to drain water until the water level in the water tank is less than 10% of the volume, and then the air valve 38 is closed, and the negative pressure formed by the inertia of the water flow drives the piston 33 to move toward the water tank 34, thereby driving the negative pressure inside the channel 211.
[0033] As can be seen from the above description, through the descaling work, the water is directly discharged through the hard water pipe 35 by utilizing the water tank 34, and the hard water pipe 35 is set downward. During the drainage process, a negative pressure state is formed inside the hard pipe. When the water level drops from 90% to 10%, the air valve 38 is opened to achieve resistance-free drainage, avoiding poor drainage caused by lack of air entering the water tank 34. By quickly discharging the water body, inertia is formed to cause negative pressure inside the water tank 34 (of course, the water tank is a sealed water tank 34), thereby achieving negative pressure in the sealing cylinder 32 and driving the piston 33 to move, thereby causing the channel 211 to form a rapid negative pressure. With the porous structure of the scale, the scale in the conveying pipeline is mainly composed of insoluble calcium carbonate magnesium and various alkaline iron salts, among which carbonate scale is mainly CaCO3 and contains a small amount of MgCO3. This type of scale is porous, and porosity is also one of the reasons for poor thermal conductivity. In addition, from the perspective of crystallization principle, the porous surface can To provide a large number of crystal nuclei, resulting in rapid precipitation of crystals, which also explains the porous structure characteristics of scale from a microscopic perspective; the porous structure of scale contains water and air. Under the action of negative pressure, the air-containing water and air in the scale will expand rapidly under the action of negative pressure, thereby bursting the scale, or the air rupture of water molecules forms an impact and causes the scale to be crushed, or it can be the combined effect of the two; in conjunction with the piston 33, using Pascal's law, that is, in a closed container, the pressure transmission is instantaneous and uniform, achieving uniform pressure transmission in various places in the channel 211, and ensuring a uniform descaling effect; by adopting a remote fixed-point water quality detection device, the structure is simple, the production and installation costs are low, all components are mature and cheap, and no additional power supply is required. By utilizing the water pressure of the water supply pipe 1 to generate electricity and cooperate with the communicator 25 for remote data transmission, there is no need for special staff to take samples. At the same time, through automatic descaling, the service life of the device can be extended and the number of maintenance times can be reduced. The provision of the air-permeable valve 38 facilitates ventilation, thereby preventing the water tank 34 from being damaged due to excessive internal pressure caused by gas generated by changes in the external environment during the water storage process.
[0034] Furthermore, the side wall of the channel 211 is also provided with a slag discharge port 213 communicating with the outside, and the slag discharge port 213 is provided with a third solenoid valve 28 electrically connected to the controller 23;
[0035] After the descaling work, the resetting and slag removal work is also included, and the resetting and slag removal work includes:
[0036] The controller 23 controls the first solenoid valve 27 and the air-permeable valve 38 to be closed, the second solenoid valve 37 and the third solenoid valve 28 to be opened, the first three-way valve 31 is connected to the sealing cylinder 32, and the second three-way valve 36 is closed.
[0037] From the above description, it can be seen that by closing the second three-way valve 36, the pressure generated by the water entering the second solenoid valve 37 causes the piston 33 to push toward the first three-way valve 31, and the first three-way valve 31 is connected to the sealing cylinder 32, so that the gas and liquid in the sealing cylinder 32 close to the first three-way valve 31 enter the channel 211 through the three-way valve, and are discharged by the third solenoid valve 28 through the channel 211.
[0038] It can be seen from the above description that by providing the slag discharge port 213, the broken scale can be directly discharged through the water flow, and at the same time the piston 33 can be reset to prepare for the next descaling work.
[0039] Furthermore, the resetting and slag removal work also includes a flushing work before the work, and the flushing work includes:
[0040] The controller 23 controls the first solenoid valve 27 to open, the first three-way valve 31 is connected to the second three-way valve 36, and the air-permeable valve 38 is opened. The second three-way valve 36 can be connected to the outside through the hard water pipe 35 for preliminary slag discharge, and can also be connected to the water tank 34 for preliminary water storage, which is convenient for the next descaling or water storage for resetting slag discharge.
[0041] From the above description, it can be seen that through the flushing work, the water pressure of the water supply pipe 1 can be utilized for flushing, and at the same time, the space created by the volume change can be filled. At the same time, due to the existence of negative pressure, the water pressure can be made stronger, the impact effect is better, and it is more convenient to remove the scale. Then, the scale is discharged through the resetting slag discharge work to ensure the discharge effect.
[0042] Furthermore, one descaling operation, one flushing operation and one resetting and slag removal operation constitute one descaling procedure, and the remote fixed-point water quality detection device can perform several descaling procedures when descaling.
[0043] Furthermore, the slag discharge port 213 is disposed on a side wall of the channel 211 close to the first solenoid valve 27 .
[0044] It can be seen from the above description that by arranging the slag discharge port 213 on the side wall of the channel 211 close to the first solenoid valve 27, all the crushed scale can be discharged conveniently during flushing.
[0045] Furthermore, when the remote fixed-point water quality detection device detects, the controller 23 controls the first solenoid valve 27 and the third solenoid valve 28 to open, the second solenoid valve 37 to close, the first three-way valve 31 and the second three-way valve 36 to communicate, and the air valve 38 to open.
[0046] Furthermore, the hard water pipe 35 is arranged vertically downward.
[0047] It can be seen from the above description that by setting the hard water pipe 35 vertically downward, the page passing through the hard water pipe 35 can be kept in a horizontal state, thereby ensuring full utilization of the water inside the water tank 34.
[0048] Furthermore, the water tank 34 is funnel-shaped.
[0049] From the above description, it can be seen that through the funnel-shaped water tank 34, since the cross-sectional area of the water tank 34 gradually decreases from top to bottom, the pressure at the second three-way valve 36 is greater, and the water can be discharged faster, thereby improving the descaling efficiency.
[0050] Furthermore, the detection head 221 is located in the channel 211 close to the first electromagnetic valve 27 ; and the hydroelectric generator 26 is located in the channel 211 far away from the first electromagnetic valve 27 .
[0051] From the above description, it can be seen that by locating the detection head 221 close to the first solenoid valve 27, water pressure can be used to impact the detection head 221, so that scale is not easily formed on the surface of the detection head 221. The water flow speed is reduced through the obstruction of the detection head 221, thereby preventing excessively fast water flow from impacting the hydroelectric generator 26 and causing damage to the generator.
[0052] Furthermore, a liquid level sensor is provided in the water tank 34 , and the liquid level sensor is electrically connected to the controller, and the controller obtains water volume information through the liquid level sensor.
