[0001] The utility model relates to the technical field of environmental monitoring sampling devices, in particular to a city public ecological environment monitoring sampling device. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality. Environmental monitoring is to determine the environmental pollution status and the level of environmental quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators and ecosystems. According to the monitoring medium or object, it can be divided into water quality monitoring, air monitoring, soil monitoring, solid waste monitoring, biological monitoring, biological pollution monitoring and ecological monitoring.

[0003] When sampling and testing water quality, it is necessary to sample water in different areas of a lake or river.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a city public ecological environment monitoring sampling device, comprising:

[0028] An installation box 1, a water pumping pipe 2 is slidably embedded in the end surface of the installation box 1, a support frame 4 is fixedly connected inside the installation box 1, a water pump 3 is fixedly connected to the top of the support frame 4, and the input end of the water pump 3 is fixedly connected to the output end of the water pumping pipe 2;

[0029] The mounting plate 9 is fixedly sleeved at the input end of the water pumping pipe 2. A plurality of connecting rods 13 are slidably connected inside the mounting plate 9. The ends of the connecting rods 13 that are far away from each other are fixedly connected to the connecting frames 5. The mesh covers 6 are fixedly connected between the adjacent connecting frames 5. The upper end of the mounting plate 9 is fixedly connected to the ring cover 10. The driving plate 7 is rotatably connected inside the ring cover 10.

[0030] The synchronous driving mechanism is arranged between the driving disk 7 and the plurality of connecting rods 13, and the surface garbage is intercepted by the mesh cover 6 to prevent the surface garbage from being sucked into the water extraction pipe 2 when the test water is extracted, causing the pipe to be blocked and affecting the normal use of the device.

[0031] like Figure 1-5 As shown, the synchronous drive mechanism includes a sliding pin 12 fixedly connected to the top end of the connecting rod 13, the sliding pin 12 is arranged at the end of the connecting rod 13 away from the connecting frame 5, and an arc guide groove 8 is opened at the end surface of the driving disk 7 corresponding to each sliding pin 12. Multiple arc guide grooves 8 are distributed and slidably connected with the corresponding sliding pins 12. By rotating the driving disk 7, multiple connecting rods 13 can be moved and driven at the same time.

[0032] like Figure 1-5 As shown, a sliding groove 11 is opened in the mounting plate 9 corresponding to each connecting rod 13, and the connecting rod 13 is slidably connected inside its corresponding sliding groove 11. Multiple sliding grooves 11 are evenly distributed in an array, and the sliding grooves 11 serve to limit the connecting rod 13.

[0033] like Figure 1-5 As shown, a shift block 16 is fixedly connected to the outer periphery of the driving disk 7, a spring 17 is fixedly connected to the notch of the mounting disk 9, a movable end of the spring 17 is fixedly connected to the shift block 16, and an automatic release mechanism is provided on the outer peripheral side of the mounting disk 9, and the driving disk 7 can be driven to rotate by the elastic force of the spring 17.

[0034] like Figure 1-5 As shown, the automatic release mechanism includes a U-shaped pin 15 slidably connected to the outer periphery of the side wall of the mounting plate 9, and an empty slot 22 adapted to the shift block 16 is opened in the middle of the U-shaped pin 15. The bottom end of the U-shaped pin 15 is fixedly connected to a floating pad 14. When the floating pad 14 is not submerged in water, the U-shaped pin 15 will slide to the lowest point under the action of gravity. At this time, the upper half of the U-shaped pin 15 will limit the shift block 16. When the floating pad 14 rises due to the buoyancy of the water, the U-shaped pin 15 will be driven to move upward. When the U-shaped pin 15 moves upward, the empty slot 22 will be at the same height as the shift block 16, and the limit of the shift block 16 by the U-shaped pin 15 can be automatically cancelled.

[0035] like Figure 1-5 As shown, a plurality of collecting tubes 20 are placed inside the installation box 1, and a floating plate 23 is fixedly connected to the bottom end of the installation plate 9, and the floating plate 23 plays a supporting role for the installation plate 9 on the water surface.

[0036] like Figure 1-5 As shown, the production end of the water pump 3 is fixedly connected with an outlet cover 21, and the diameter of the lower end cover of the outlet cover 21 is adapted to the diameter of the top end of the collecting tube 20. The outlet cover 21 can prevent water from splashing out of the collecting tube 20 when extracting test water, and prevent water samples from different areas from mixing.

[0037] like Figure 1-5 As shown, the side wall of the installation box 1 is fixedly connected to two symmetrically distributed fixing mechanisms, which include an L-shaped block 18 fixedly connected to the side wall of the installation box 1, and the vertical end of the L-shaped block 18 is threadedly connected with a locking bolt 19. The device can be fixed by the locking bolt 19, which is convenient for installing the device on a mobile tool and reducing the manpower consumption when carrying it.

[0038] Working principle: When using the device to perform water intake detection on the water surface, throw the input end of the water pumping pipe 2 into the water. When the water pumping pipe 2 is thrown into the water, the floating plate 23 can play a supporting role and keep the installation plate 9 on the water surface. At the same time, the floating pad 14 will also rise due to the buoyancy of the water, driving the U-shaped card pin 15 to move upward. When the U-shaped card pin 15 moves upward, the empty groove 22 will be at the same height as the shift block 16. At this time, the shift block 16 is no longer limited by the U-shaped card pin 15. The shift block 16 drives the drive disk 7 to rotate through the elastic force of the spring 17. When the drive disk 7 rotates, it squeezes multiple sliding pins 12 at the same time through multiple arc guide grooves 8 to move, but The connecting rod 13 at the lower end of the sliding pin 12 is limited by the sliding groove 11, so that when the arc-shaped guide groove 8 squeezes the sliding pin 12, it drives the connecting rod 13 to move linearly along the sliding groove 11, so that multiple connecting rods 13 slide synchronously and move away from each other. In the process of the connecting rods 13 moving away from each other, the function of opening the net cover 6 is realized, which plays a role in intercepting surface garbage. It can prevent surface garbage from being sucked into the water pump 2 when extracting test water, and prevent the pipeline from being blocked and affecting the normal use of the device. The device is simple and quick to use. After the water pump 2 falls into the water, the net cover 6 can be automatically unfolded to bounce off and intercept surface garbage.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
