Description
Technical Field
[0001] The utility model belongs to the field of monitoring systems for river inlet drainage outlets. Background Art
[0002] To monitor the water quality of each river inlet drainage outlet for convenient management, the environmental protection department will establish a monitoring system for river inlet drainage outlets (hereinafter referred to as the monitoring system). The existing monitoring system for river inlet drainage outlets mainly includes a computer installed with corresponding monitoring software and multiple groups of sensors. One group of sensors is set at each river inlet drainage outlet, and there can be multiple sensors in one group, which are respectively used for detecting parameters such as pH, dissolved oxygen, conductivity, turbidity, etc. The sensors detect the water quality of the river inlet and transmit the detected data to the computer, and the water quality status of each river inlet can be obtained in real time from the computer.
[0003] In the existing monitoring system, the sensors are arranged in the pipeline of the river inlet drainage outlet, and the water flow in the pipeline is not clean water. A large amount of impurities contained therein will adhere to the sensors, forming water scale, isolating the contact between the sensors and the river water, resulting in a decrease in detection accuracy. Regular maintenance is required to remove the water scale on the sensors. However, the river inlets are widely distributed, and each maintenance requires a large amount of time cost, transportation cost and labor cost, and the maintenance is troublesome.
[0004] In addition, the existing sensors are directly fixed in the river inlet. When the water flow is large in the rainy season, the flow velocity of the river inlet is large, and there are sundries such as sediment in it, which easily causes the sensors to be worn and malfunction, and the service life is relatively low.
[0005] In summary, the existing monitoring system has the defects of troublesome sensor maintenance and relatively low service life. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a monitoring system for river inlet drainage outlets. The utility model has the advantages of simple sensor maintenance and long service life.
[0007] Technical solution of the utility model: The river inlet drainage outlet monitoring system includes a computer and multiple groups of sensors. Each group of sensors includes multiple sensors. It is characterized in that: it further includes a water tank. The top of the water tank is provided with a first water inlet, the bottom of the water tank is provided with a first water outlet. A vertical partition is arranged in the water tank. The two sides of the partition respectively form a first chamber and a second chamber. Both the first chamber and the second chamber are communicated with the first water inlet. A filter is arranged at the top of the first chamber. A rotor with a hollow structure is arranged at the first water outlet. The rotor is located at the bottom of the partition. An annular sealing surface is formed between the rotor and the water tank. A power mechanism is arranged on the rotor. The detection ends of multiple sensors in the same group all extend into the rotor. A second water inlet located on one side of the partition is arranged at the top of the rotor. A second water outlet is arranged on the side wall of the lower part of the rotor. First water trough and a second water trough are arranged on the side wall of the water tank. The first water trough is located below the first chamber, and the second water trough is located below the second chamber. The lower ends of the first water trough and the second water trough are both communicated with the first water outlet. The upper ends of the first water trough and the second water trough are both located between the upper and lower ends of the sealing surface and are higher than the second water outlet.
[0008] In the aforesaid river inlet drainage outlet monitoring system, a plurality of buckles distributed around the first water inlet are arranged at the top of the water tank.
[0009] In the aforesaid river inlet drainage outlet monitoring system, the power mechanism includes an impeller located above the water tank. The impeller is coaxial with the first water inlet. A speed reducer is arranged in the second chamber. The input end of the speed reducer is vertically upward, and the output end of the speed reducer is horizontally outward. The input end of the speed reducer is connected to the impeller through a connecting rod. A gear is arranged at the output end of the speed reducer. An annular groove is arranged on the top surface of the rotor, and teeth meshing with the gear are arranged on the bottom surface of the annular groove.
[0010] In the aforesaid river inlet drainage outlet monitoring system, an electric slip ring is arranged on the wire harness of the sensor. Multiple sensors in the same group share one electric slip ring.
[0011] In the aforesaid river inlet drainage outlet monitoring system, seen from the rotation direction of the rotor, both the first water trough and the second water trough are close to the partition and are located at the rear side of the corresponding end of the partition.
[0012] In the aforesaid river inlet drainage outlet monitoring system, the axis of the second water outlet sequentially passes through the axis of the second water inlet and the axis of the rotor.
[0013] In the aforesaid river inlet drainage outlet monitoring system, the sensor establishes a network connection with the computer through a mobile network module.
[0014] In the aforesaid river inlet drainage outlet monitoring system, the river inlet drainage outlet monitoring system further includes a storage battery. A photovoltaic charging device is connected to the storage battery, and the mobile network module is connected to the storage battery.
[0015] In the above-mentioned monitoring system for river inlet drainage outlets, the partition board is V-shaped, and the second chamber is located within the acute angle included angle of the partition board.
[0016] In the above-mentioned monitoring system for river inlet drainage outlets, the acute angle included angle of the partition board is 30 - 60°.
[0017] Compared with the prior art, the utility model uses a water tank to collect the river water flowing into the river. A partition board is arranged in the water tank to form two chambers. A filter is provided at the top of one chamber to filter the river water flowing into the river into clean water for storage. The other chamber is connected to the river water flowing into the river. By arranging a hollow rotor at the bottom of the water tank and inserting the detection end of the sensor into the inner cavity of the rotor, the clean water and the river water flowing into the river are alternately accessed by using the rotational movement of the rotor, so that the sensor can intermittently contact the river water flowing into the river to detect the corresponding water quality information, and most of the time it is immersed in the clean water, avoiding the formation of water scale, greatly reducing the maintenance frequency and making the maintenance simple. The water tank of the utility model is used to be fixed at the bottom of the river inlet to avoid the direct impact of the water flow on the sensor. The speed of the water flow flowing over the surface of the sensor is low, making the sensor not easy to wear and improving the service life of the sensor. Therefore, the utility model has the advantages of simple sensor maintenance and long service life.
[0018] In addition, through further improvement, the consumption of clean water in the water tank is reduced, making the filter not easy to be blocked and prolonging the service life of the filter. The rotation of the rotor is driven by the water flow power at the river inlet, and the power of the rotor does not need to be provided by a storage battery. At the river inlet where it is not easy to connect to the mains power, when using the storage battery to provide the power required for the sensor and the mobile network module, the consumption of the storage battery can be reduced, providing a guarantee for the continuous operation of the system.

Detailed Embodiments
[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.
[0024] Embodiment 1. The monitoring system for the river inlet drainage outlet is as Figure 1 shown, and includes a computer 1 and multiple groups of sensors 2. Each group of sensors 2 includes multiple sensors 2, and the features are as follows:
[0025] The monitoring system further includes a water tank 3. The top of the water tank 3 is provided with a first water inlet 4, the bottom of the water tank 3 is provided with a first water outlet 5, a vertical partition 6 is arranged inside the water tank 3. The partition 6 is V-shaped when viewed from above, the acute angle included angle of the partition 6 is 45°, and both sides of the partition 6 respectively form a first chamber 7 and a second chamber 8. The second chamber 8 is located within the acute angle included angle of the partition 6. Both the first chamber 7 and the second chamber 8 are communicated with the first water inlet 4. The top of the first chamber 7 is provided with a filter 9. A rotor 10 with a hollow structure is arranged at the first water outlet 5. The rotor 10 is located at the bottom of the partition 6 and maintains a very small gap. An annular sealing surface 15 is formed between the rotor 10 and the water tank 3. A power mechanism is arranged on the rotor 10. The detection ends of multiple sensors 2 within the same group of sensors 2 all extend into the rotor 10. The top of the rotor 10 is provided with a second water inlet 11 located on one side of the partition 6. The side wall of the lower part of the rotor 10 is provided with a second water outlet 12. The side wall of the water tank 3 is provided with a first water tank 13 and a second water tank 14. The first water tank 13 is located below the first chamber 7, and the second water tank 14 is located below the second chamber 8. The lower ends of both the first water tank 13 and the second water tank 14 are communicated with the first water outlet 5. The upper ends of both the first water tank 13 and the second water tank 14 are located between the upper and lower ends of the sealing surface 15 and are higher than the second water outlet 12.
[0026] A plurality of buckles 16 are distributed around the first water inlet 4 at the top of the water tank 3.
[0027] The power mechanism includes an impeller 17 located above the water tank 3. The impeller 17 is coaxial with the first water inlet 4. A speed reducer 18 is arranged in the second chamber 8. The input end of the speed reducer 18 is vertically upward, and the output end of the speed reducer 18 is horizontally outward. The input end of the speed reducer 18 is connected to the impeller 17 through a connecting rod 19. Preferably, a bracket for maintaining its vertical state is arranged on the connecting rod 19. The bracket is fixed to the partition 6 or the water tank. The connecting rod 19 passes through the bracket. A gear 20 is arranged at the output end of the speed reducer 18. Tooth teeth 21 matching with the gear 20 are arranged on the bottom surface of the annular groove 22 on the top surface of the rotor 10.
[0028] An electric slip ring 23 is provided on the wire harness of the sensor 2, and multiple sensors 2 within the same group share one electric slip ring 23. The power supply and signal transmission of multiple sensors 2 are both through the electric slip ring 23. The electric slip ring 23 has multiple channels and can be purchased.
[0029] Viewed from the rotation direction of the rotor 10, the first water tank 13 and the second water tank 14 are both close to the partition plate 6 and are located at the rear side of the corresponding end of the partition plate 6.
[0030] The axis of the second water outlet 12 sequentially passes through the axis of the second water inlet 11 and the axis of the rotor 10.
[0031] The sensor 2 transmits signals to the mobile network module 24 through the electric slip ring 23, and the mobile network module 24 establishes a network connection with the computer 1. The sensor 2 gets power from the mobile network module 24. The river inlet and drain outlet monitoring system further includes a storage battery 25, a photovoltaic charging device 26 is connected to the storage battery 25, and the mobile network module 24 is connected to the storage battery 25. These structures described in this paragraph are taken from the existing monitoring system and can be used without modification.
[0032] Usage method of Embodiment 1:
[0033] As Figure 1 shown, a through hole is opened at the bottom of the pipeline of the river inlet and drain outlet, and the water tank 3 is connected to the bottom of the pipeline by using a buckle 16. The river water can enter the water tank 3 from the first water inlet 4. Part of it directly enters the second chamber 8 without treatment, and the other part is filtered by the filter 9. After removing impurities and scaling ions, it enters the first chamber 7.
[0034] During the flowing process of the river water, the impeller 17 is driven to rotate counterclockwise when viewed from above in a top view. The impeller 17 drives the gear 20 to rotate slowly through the connecting rod 19 and the speed reducer 18. The speed reducer 18 plays a role in reducing the rotation speed of the gear 20 and amplifying the driving force of the impeller 17, ensuring that the gear 20 can still rotate when the flowing speed of the river water is slow. The gear 20 meshes with the teeth 21 in the annular groove 22, driving the rotor 10 to rotate. The rotation speed of the rotor 10 is preferably 5 to 30 min / r. It is possible to rotate the corresponding size of the impeller 17 according to the flowing speed range of the water flow. To ensure the purity of the clean water in the first chamber 7, fine teeth should be used on the gear 20. Correspondingly, the depth of the annular groove 22 can be reduced, and it is difficult for the river water in the second chamber 8 to enter the first chamber 7.
[0035] As Figure 2As shown, when the second water inlet 11 is inside the first chamber 7, clean water enters the rotor 10. At this time, the second water outlet 12 is blocked, and the clean water cannot be discharged from the first water outlet, reducing the consumption of clean water. The filter 9 is not easily blocked, reducing the maintenance frequency. As the rotor 10 rotates, when the second water inlet 11 enters the second chamber 8, the inside of the rotor 10 is connected to the second chamber 8, and the incoming river water in the second chamber 8 enters the inside of the rotor 10. The second water outlet 12 is connected to the first water outlet 5 through the second water tank 14, and the clean water inside the rotor 10 is discharged from the first water outlet 5. At this time, the sensor 2 detects the first signal, that is, the water quality signal of the incoming river water. The rotor 10 continues to rotate. When the second water inlet 11 returns to the first chamber 7 again, the inside of the rotor 10 is connected to the first chamber 7, and the clean water in the first chamber 7 enters the inside of the rotor 10. The second water outlet 12 is connected to the first water outlet 5 through the first water tank 13, and the incoming river water inside the rotor 10 is discharged from the first water outlet 5. The sensor 2 is immersed in the clean water, reducing the contact time with the sewage and greatly extending the maintenance period of the sensor 2. At this time, the sensor 2 detects the second signal, that is, the water quality signal of the clean water, and this signal is a useless signal. During the period when the rotor 10 rotates one week, the sensor 2 is immersed in the clean water for most of the time.
[0036] As Figure 3 shown, for any sensor 2, the mobile network module 24 transmits the alternately generated first signal and second signal to the computer. The computer 1 compares the two signals and takes the signal representing the poorer water quality as the water quality signal of the incoming river water. The storage battery 25 supplies power to the mobile network module 24 and the sensor 2, and the photovoltaic charging device 26 replenishes the electric energy of the storage battery 25. Since the power for driving the rotor 10 to rotate is not obtained from the storage battery 25, the power consumption of the storage battery 25 is low, and even in long-term rainy weather, the power will not be exhausted.
[0037] Embodiment 2. Compared with Embodiment 1, the photovoltaic charging device 26 and the storage battery 25 are cancelled, and the mobile network module 24 obtains power from the commercial power.
