Description

Technical Field

[0001] The utility model relates to the technical field of water pollution monitoring, in particular to a water pollution monitoring and early warning device. Background Art

[0002] Inland river environmental pollution accidents caused by water transportation accidents, pipeline transportation, coastal bridge and road traffic accidents are characterized by uncertainty and sensitivity, which cause serious damage to the environment and are very likely to cause major economic losses and adverse international impacts. They are high-risk areas for environmental pollution accidents in various countries. Due to the large number of ecological and environmental sensitive areas in inland waters, the wide range of river basins, complex hydrogeological and meteorological conditions, and limited use of emergency equipment, there are still shortcomings in the ecological risk prevention and control of oil spills and chemical leaks, as well as the ecological damage assessment technology after emergency disposal of accidents.

[0003] The patent with publication number CN116754737A discloses a device and method for monitoring and early warning ecological risks of sudden water pollution in a river basin. The patent uses an electric propeller to drive the main body of the buoy to travel in the water body of the river basin, thereby driving the sampling and monitoring cylinder to move in the water body of the river basin with sudden water pollution, so as to flexibly complete the sampling and monitoring process. The device has low difficulty in layout, high flexibility in use, and good application effect. However, in this solution, there is one monitoring inner cylinder, and since it cannot be cleaned, the area for single sampling and monitoring can only be unique without affecting the accuracy of the data, and the effect of multiple sampling and monitoring cannot be achieved.

[0004] In addition, the patent with announcement number CN216594356U discloses a groundwater stratified sampling device, which drives the bottle stopper at the lower end of the connecting rod to rotate through a driving shaft, so that the channel on the bottle stopper and the through hole on the sampling bottle are staggered or overlapped, so as to realize the closure or opening of the sampling bottle, that is, the disturbance to the groundwater is reduced, and it is not limited by the sampling depth; at the same time, by adjusting the position of the through hole on the sampling bottle, a single driving mechanism controls the sampling of multiple sampling bottles, which reduces the cost of using the device and the difficulty of maintenance. However, during the use of this patent, the angle between the channel and the first through hole needs to be accurately set, and the initial position of the first driving motor needs to be accurately positioned, otherwise it is difficult to ensure that the channel and the through hole are staggered or overlapped, which will further affect the groundwater sampling work and cause inconvenience in the use process.

[0005] In view of this, designing a water pollution monitoring and early warning device that can perform water quality sampling and monitoring multiple times continuously and reduce the operation complexity during the sampling process has become a technical problem that technical personnel in this field urgently need to solve.

A piston 11 is slidably connected in the accommodating chamber 9 along the vertical direction. A second through hole 10 is provided on the side wall of the accommodating chamber 9 near the first through hole 8. The piston 11 can selectively block the first through hole 8 and the second through hole 10. In a specific embodiment of the present utility model, when the piston 11 is located at the lowermost end of the accommodating chamber 9, the piston 11 can simultaneously block the first through hole 8 and the second through hole 10. For details, refer to Figure 3 When the piston 11 moves upward along the accommodating chamber 9, the piston 11 can contact the first through hole 8 and the second through hole 10, and the external water can enter the bottle body 6 through the first through hole 8 and the second through hole 10 in sequence. Figure 4 .

[0053] Before use, the sampling bottle 4 of the utility model should be vacuumed to avoid disturbance of the water body caused by gas being discharged from the sampling bottle 4. At the same time, in order to prevent the piston 11 from being unable to seal the first through hole 8 and the second through hole 10 in a natural state, a first compression spring 12 is arranged in the accommodating chamber 9 of the utility model, one end of the first compression spring 12 is connected to the piston 11, and the other end of the first compression spring 12 is connected to the end wall of the accommodating chamber 9. Under the action of the first compression spring 12, the piston 11 is located at the lower end of the accommodating chamber 9, and at this time, the piston 11 can simultaneously seal the first through hole 8 and the second through hole 10.

[0054] The end surface of the piston 11 near the first through hole 8 is movably connected with a rotating ball 13, and the rotating ball 13 is clearance-matched with the first through hole 8. The sealing component selectively drives the rotating ball 13 to move toward the housing 1 to enable the piston 11 to unblock the first through hole 8 and the second through hole 10.

[0055] Preferably, refer to Figure 6-8 As shown, the closure assembly includes a support plate 15, a slide cylinder 16, a driving block 17 and a stop block 18. The support plate 15 is located below the housing 1, and the support plate 15 is fixedly connected to the housing 1 through a connecting rod 14, and the bottle mouth is arranged through the support plate 15, and the sampling bottle 4 can be further fixed by the support plate 15; a plurality of slide cylinders 16 are fixedly installed on the support plate 15, and driving blocks 17 and stop blocks 18 are respectively slidably connected in two adjacent slide cylinders 16, and the driving blocks 17 and the stop blocks 18 are arranged alternately, and the driving blocks 17 are arranged one by one with the rotating balls 13, and when the driving blocks 17 and the slide cylinder 16 slide relative to each other, the rotating balls 13 can be selectively driven to move toward the housing 1.

[0056] Preferably, the closing assembly further comprises a driving disk 19, which is rotatably connected to the bottom of the support plate 15, a notch 20 being provided at the edge of the driving disk 19, and a plurality of slides 16 being distributed in a circular array along the axis of the driving disk 19; a plurality of second compression springs 21 are provided in the plurality of slides 16 in a one-to-one correspondence, one end of the second compression spring 21 being connected to the end wall of the slide 16, and the other ends of the second compression springs 21 in two adjacent slides 16 being connected to the driving block 17 and the stop block 18, respectively, the driving block 17 and the stop block 18 being slidably connected to the slide 16 along the radial direction of the driving disk 19, the ends of the driving block 17 and the stop block 18 away from the slide 16 are respectively slidably connected to the edge of the driving disk 19, a groove 22 is provided at the end face of the driving block 17 close to the rotating ball 13, the end face of the groove 22 is slidably connected to the rotating ball 13, and the end face of the groove 22 in the direction close to the driving disk 19 is inclined in a direction away from the housing 1. When the driving block 17 is embedded in the notch 20, the driving block 17 drives the rotating ball 13 to move toward the shell 1, so that the piston 11 releases the blockage of the first through hole 8 and the second through hole 10; when the stopping block 18 is embedded in the notch 20, the rotating ball 13 is located at the first through hole 8, and the piston 11 blocks the first through hole 8 and the second through hole 10.

[0057] Specifically, the closure assembly further includes a driving rod 23, a tension spring 25 and a follower rod 24. The driving rod 23 is located below the driving disk 19, one end of the driving rod 23 is coaxially connected to the driving disk 19, and the other end of the driving rod 23 is provided with an inclined surface, so that when the driving block 17 rotates, the driving block 17 or the stop block 18 embedded in the notch 20 can be driven to escape from the notch 20, that is, when the inclined surface is in sliding contact with one of the driving block 17 or the stop block 18, the driving block 17 or the stop block 18 can be driven to gradually escape from the notch 20 by overcoming the elastic force of the second compression spring 21; the follower rod 24 is fixedly connected to the lower surface of the driving disk 19, and one end of the driving rod 23 away from the axis of the driving disk 19 is connected to the follower rod 24 through the tension spring 25.

[0058] During use, one of the driving block 17 or the stop block 18 is embedded in the notch 20. During the rotation of the other end of the driving rod 23, the length of the tension spring 25 continues to increase, and the driving rod 23 contacts one of the driving block 17 or the stop block 18 to make it escape from the notch 20. Further, the driving disk 19 contracts under the action of the tension spring 25, so that the notch 20 is engaged with the next driving block 17 or the stop block 18. During the rotation of the driving rod 23, the above operation will be repeated continuously. When the stop block 18 is embedded in the notch 20, the pistons 11 corresponding to the driving blocks 17 are in a state of blocking the first through hole 8 and the second through hole 10. When one of the driving blocks 17 is embedded in the notch 20, the piston 11 corresponding to this driving block 17 releases the blockage of the first through hole 8 and the second through hole 10.

[0059] In addition, the closure assembly further includes a limit rod 26, a first drive motor 27, a control unit 28 and a power supply 37. The limit rod 26 is fixedly connected to the lower surface of the drive disk 19, and the limit rod 26 is located between the drive rod 23 and the follower rod 24. The limit rod 26 is used to achieve abutment and limit the drive rod 23 when the follower rod 24 moves close to the drive rod 23. A box is fixedly connected to the upper part of the support plate 15, and a first drive motor 27 is fixedly connected to the box. The output shaft of the first drive motor 27 passes through the support plate 15 and the drive disk 19 and is connected to the drive rod 23 in a transmission manner. The output shaft of the first drive motor 27 is connected to the support plate 15 and the drive disk 19 through a bearing 38. The housing 1 is provided with an installation cavity, and the installation cavity is provided with a power supply 37 and a control unit 28. The power supply is a battery. The first drive motor 27, the power supply 37 and the control unit 28 are electrically connected to the control unit 28 respectively. The control unit 28 is a PLC device.

[0060] Optionally, a main control box 29 is installed in the shell 1, and the main control box 29 is also installed in the installation cavity. The input end of the main control box 29 is connected to the output end of the sensor module 5, and the output end of the main control box 29 is electrically connected to the control unit 28. The control unit 28 has a built-in communication module, and the control unit 28 is connected to a host computer (not shown in the figure) through the communication module.

[0061] Preferably, refer to Figure 5 The sampling bottle 4 also includes a bottle bottom 30 fixedly connected to the shell 1, the sensor module 5 is installed on the bottle bottom 30, the bottle bottom 30 and the bottle body 6 are detachably connected by threads, and a sealing ring 31 is arranged between the bottle bottom 30 and the bottle body 6, and the sealing ring 31 is made of polytetrafluoroethylene.

[0062] After the use of the utility model, the support plate 15 is disconnected from the shell 1, and the bottle body 6, the bottle cap 7 and the bottle bottom 30 are disconnected, so that the bottle body 6, the bottle cap 7 and the bottle bottom 30 can be cleaned.

[0063] Refer again Figure 1 The propeller assembly includes a second drive motor 32 and a propeller 33. The second drive motor 32 is fixedly connected to the through channel 2. The second motor is in transmission connection with the propeller 33, and the second drive motor 32 is electrically connected to the control unit 28. The control unit 28 controls the second drive motor 32 to start, which can drive the entire monitoring and early warning device to change position. In order to ensure that impurities in the water enter the through channel 2, filter screens 3 are provided at both ends of the through channel 2.

[0064] In order to ensure that the propeller 33 can be embedded in the water during the use of the utility model, and to ensure that the entire monitoring and early warning device will not flip over when the sampling bottle 4 does not store water, a hollow cavity 34 is arranged in the shell 1 located above the through channel 2. The hollow cavity 34 is used to increase the volume of the entire monitoring and early warning device, thereby increasing the buoyancy of the water body, and avoiding the situation where the entire device sinks and cannot return after the sampling bottle 4 takes water. The support plate 15 is connected to the conical block 36 through the connecting rope 35, and the conical block 36 achieves a downward pulling effect on the support plate 15, which can ensure that the support plate 15 is located below the shell 1 during use, and avoid the device flipping over when the sampling bottle 4 is empty.

[0065] The working principle of this utility model:

[0066] Before use, the sampling bottle 4 needs to be vacuumed to ensure that one of the stop blocks 18 is embedded in the notch 20. The utility model is explained by taking the number of stop blocks 18 and drive blocks 17 as N as an example. By adjusting the rotation of the first drive motor 27 so that the rotation angle of the first drive motor 27 is 180 / N, the other end of the drive rod 23 can drive the stop block 18 to escape from the notch 20.

[0067] When in use, the first step is to place the water pollution monitoring and early warning device of the utility model in an area where sudden water pollution occurs in an inland river, and send instructions to the control unit 28 through the host computer, so that the control unit 28 controls the start of the second drive motor 32 to enable the water pollution monitoring and early warning device of the utility model to reach the area to be monitored. In the second step, the first driving motor 27 rotates an angle of 180 / N. During this process, the driving rod 23 pushes the stop block 18 to make it disengage from the notch 20, and further drives the driving disk 19 to rotate under the action of the tension spring 25 until one of the driving blocks 17 is embedded in the notch 20. At this time, the driving rod 23 abuts against the limit rod 26, and the driving block 17 squeezes the rotating ball 13 to make the corresponding piston 11 move upward, and then the piston 11 releases the blockage of the first through hole 8 and the second through hole 10, so that the external water passes through the first through hole 8 and the second through hole 10 and continuously enters the sampling bottle 4. The water in the sampling bottle 4 contacts the sensor module 5, and the sensor module 5 transmits the collected water quality information to the main control box 29 in the form of an electrical signal. The main control box 29 is electrically connected to the control unit 28 and transmits it to the host computer through the communication module. The host computer learns the water quality of this water area and rotates the second driving motor 32 by an angle of 180 / N again. In this process, the driving rod 23 pushes the driving block 17 to disengage from the notch 20, and further drives the driving disk 19 to rotate under the action of the tension spring 25 until the next stop block 18 is embedded in the notch 20. At this time, the driving rod 23 abuts against the limit rod 26, and the sampling bottle 4 for sampling is completed. Under the action of the elastic force of the first compression spring 12, the piston 11 moves downward, and the piston 11 moves downward to block the first through hole 8 and the second through hole 10, completing the water quality monitoring process of this water area. The third step is to send an instruction to the control unit 28 through the host computer, so that the control unit 28 controls the start of the second drive motor 32, so that the water pollution monitoring and early warning device of the utility model reaches other areas to be monitored, and repeat the second step to monitor the current water area again. The fourth step is to send an instruction to the control unit 28 through the host computer, so that the control unit 28 controls the start of the second drive motor 32, so that the water pollution monitoring and early warning device of the utility model returns to the initial position, and complete this monitoring work.

[0068] Compared with the patent with announcement number CN216594356U which discloses a groundwater stratification sampling device, the sampling of the utility model does not need to accurately control the initial position of the first drive motor 27. It only needs to ensure that when the first drive motor 27 rotates 180 / N, it can drive the stop block 18 and the drive block 17 embedded in the notch 20 to come out, and there is no need to adjust the angle of the device in the sampling bottle 4, thereby reducing the difficulty during assembly.
