Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a lake water sampling and testing device for environmental protection. Background Technology

[0002] In environmental protection, it is often necessary to test the water environment of lakes. During the testing process, water samples from different areas and depths need to be collected first, and then put into a water quality testing instrument for testing to ensure the accuracy of water quality testing.

[0003] Chinese Utility Model Announcement No. CN221078170U discloses a water environment monitoring device for environmental protection, comprising a telescopic detection mechanism, a detection mechanism, and a collection mechanism. The detection mechanism is located outside the telescopic detection mechanism, and the collection mechanism is located below the telescopic detection mechanism. The telescopic detection mechanism includes a rotating shaft, a winding wheel, and a suspension rope. The rotating shaft is movably installed at the inner end of the detection mechanism, the winding wheel is fixedly installed at the outer end of the rotating shaft, and the suspension rope is fixedly installed at the outer end of the winding wheel. This water environment monitoring device for environmental protection incorporates a telescopic detection mechanism. The position of the rotating shaft is defined by a mounting plate and a motor. The rotating shaft defines the position of the winding wheel, and the winding wheel defines the position of the suspension rope. This facilitates fixing the rotating shaft and enabling it to rotate. The motor then drives the rotating shaft to rotate, which in turn drives the winding wheel to rotate, causing the suspension rope to extend and retract, allowing for data collection in deeper waters.

[0004] The applicant discovered some shortcomings in the use of the patent: while the filter screen can filter out impurities in the water when taking water samples, when there is large debris in the water, such as garbage bags or aquatic plants, it will adhere to the surface of the filter screen during extraction, affecting the normal sampling process. It is also necessary to raise the entire device to the surface of the water for manual cleaning, which affects the sampling efficiency.

[0005] Therefore, this utility model designs a lake water sampling and testing device for environmental protection to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a lake water sampling and testing device for environmental protection, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lake water sampling and testing device for environmental protection, comprising: a waterproof box, a telescopic detection mechanism connected to the top of the waterproof box, a water pump installed at the bottom of the telescopic detection mechanism, an outlet pipe connected to one end of the water pump, a storage cylinder movably installed at the bottom of the outlet pipe, an inlet pipe connected to the other end of the water pump, a threaded sleeve movably installed at one end of the inlet pipe, a filter plate provided on the threaded sleeve, a rotating shaft rotatably installed at one end of the waterproof box, a rotating plate installed at one end of the rotating shaft, a brush plate in contact with the filter plate at one end of the rotating plate, and a fixing mechanism for easy replacement of the brush plate. When large debris adheres to the surface of the filter plate, rotating the rotating shaft causes the rotating plate to rotate, cleaning the large debris and avoiding interference with the normal sampling process.

[0008] Preferably, the fixing mechanism includes two waterproof cylinders, which are fixedly installed on the top of the rotating plate. Insert rods are slidably installed between the upper and lower ends of the waterproof cylinders, and the insert rods are slidably connected to the rotating plate. A movable disc is fixedly installed on the outer wall of the insert rod, and the movable disc is slidably installed inside the waterproof cylinder. A spring is connected between the top of the movable disc and the top inner wall of the waterproof cylinder, and the spring is sleeved on the outside of the insert rod. One end of the rotating plate has a slot for inserting a brush plate, and the insert rod passes through the slot. The top of the brush plate has a hole for slidably connecting with the insert rod. Pulling the two insert rods causes them to rise and leave the slot, causing the movable disc to rise and compress the spring. Then, the brush plate is inserted into the slot. Releasing the insert rods allows them to be inserted into the hole by the restoring force of the spring, completing the installation of the brush plate. This method is more convenient than bolt fixing.

[0009] Preferably, the tops of the two insertion rods are connected to the bottom sides of the pull plate, respectively. Through the pull rods, the operator can pull both insertion rods simultaneously with one hand, which is more convenient.

[0010] Preferably, a connecting pipe is installed on the top of the waterproof tank, and an installation plate is installed at one end of the connecting pipe. A camera is located at the center of the installation plate. The camera allows staff to observe the underwater environment and avoids areas with abundant aquatic plants to prevent entanglement.

[0011] Preferably, the mounting plate is provided with several lights on the outer diameter of one end of the camera to increase the brightness of the camera and facilitate observation by staff.

[0012] Preferably, a storage battery is provided in the middle of the bottom inner wall of the waterproof tank. The storage battery increases the energy and increases the overall weight of the waterproof tank, making it more stable in water.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a rotating shaft to drive the rotating plate to rotate, which in turn causes the brush plate to rotate. The brush plate scrapes away large debris adsorbed on the surface of the filter plate, avoiding interference with normal sampling. It eliminates the need for manual cleaning by staff after raising the waterproof box to the water surface through a telescopic detection mechanism, thus improving sampling efficiency.

[0015] 2. This utility model, through the setting of the fixing mechanism, allows for easy replacement of the brush plate when it is worn. Pulling the pull plate upwards causes the two insert rods to rise and leave the insertion hole. As the insert rods rise, the movable plate rises and compresses the spring, allowing the brush plate to be removed from the slot for replacement. During installation, the new brush plate is inserted into the slot, the pull plate is released, and the restoring force of the spring allows the insert rod to be inserted into the insertion hole to fix the brush plate, thus completing the installation. The operation is convenient and facilitates brush plate replacement for staff. Attached Figure Description

The specific structure of the telescopic detection mechanism 2 is described in detail in the announcement number: CN221078170U, and will not be described in detail here. A threaded cover is installed at the bottom of the outlet pipe 4, the upper outer wall of the storage cylinder is rotatably installed by threads and the threaded cover, and the outer walls of the threaded sleeve and the inlet pipe are rotatably installed by threads.

[0025] Please see Figure 4-5 In this embodiment: the fixing mechanism 12 includes two waterproof cylinders 121, which are fixedly installed on the top of the rotating plate 10. A rod 122 is slidably installed between the upper and lower ends of the waterproof cylinder 121. The rod 122 is slidably connected to the rotating plate 10. A movable disc 123 is fixedly installed on the outer wall of the rod 122. The movable disc 123 is slidably installed inside the waterproof cylinder 121. A spring 124 is connected between the top of the movable disc 123 and the top inner wall of the waterproof cylinder 121. The spring 124 is sleeved on the outside of the rod 122. One end of the rotating plate 10 is provided with a slot 125 for insertion into the brush plate 11. The rod 122 passes through the slot 125. The top of the brush plate 11 is provided with an insertion hole 126 for slidably connecting with the rod 122. The spring 124 can be made of stainless steel to avoid rusting.

[0026] Please see Figure 4 In this embodiment: the tops of the two insert rods 122 are respectively connected to the bottom sides of the pull plate 127.

[0027] Please see Figure 6 In this embodiment: a connecting pipe 13 is installed on the top of the waterproof box 1, and an installation plate 14 is installed at one end of the connecting pipe 13. A camera 15 is provided at the center of the installation plate 14. The connecting pipe 13 facilitates cable routing.

[0028] Please see Figure 6 In this embodiment: the mounting plate 14 is provided with several lights 16 on the outer diameter of one end of the camera 15. When the brush plate rotates to the top, it can wipe the surface of the camera and the lights.

[0029] Please see Figure 2In this embodiment: a storage battery 17 is provided in the middle of the bottom inner wall of the waterproof box 1.

[0030] Working principle: The telescopic detection mechanism 2 is installed on the boat. The telescopic detection mechanism 2 lowers the waterproof tank 1 into the water, and the water pump 3 is started to draw water into the collection cylinder 5 for sampling. The filter plate 8 can filter impurities in the water. After sampling, the telescopic detection mechanism 2 drives the waterproof tank 1 to rise, and the staff can remove the collection cylinder 5 for testing. When there is large debris in the water, such as plastic bags, aquatic plants, etc., which are adsorbed on the outside of the filter plate 8, it will affect the sampling. The rotating shaft 9 can be rotated to make the rotating plate 10 rotate. The rotating plate 10 drives the brush plate 11 to rotate. The brush plate 11 cleans the debris adsorbed on the outside of the filter plate 8 to ensure normal sampling. The underwater environment can be observed through the camera 15 and the lighting 16. When there is a lot of aquatic plants underwater, the boat can be sailed to replace the detection device to avoid entanglement. When the brush plate 11 is rotated to the top, it can also be used to wipe the camera 15 and the lighting lamp 16. When the brush plate 11 is worn and needs to be replaced, the operator pulls the pull plate 127 upward, which drives the insertion rod 122 to rise. The insertion rod 122 drives the movable plate 123 to rise and squeeze the spring 124. The insertion rod 122 leaves the slot 125 and the insertion hole 126, so the brush plate 11 can be pulled out from the slot 125 for replacement. Then, the new brush plate 11 is inserted into the slot 125. The pull plate 127 is released, and the restoring force of the spring 124 causes the insertion rod 122 to fall into the insertion hole 126, thus completing the installation of the brush plate 11. The operation is convenient and the brush plate 11 can be easily replaced. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
