Description

Technical Field

[0001] This utility model relates to the field of water environment monitoring and sampling technology, specifically a water environment monitoring and sampling device for watershed management. Background Technology

[0002] Environmental monitoring is primarily aimed at clearly understanding the degree of environmental pollution, thereby enabling corresponding measures to address environmental pollution problems. Environmental monitoring is characterized by its rapid and accurate implementation. Its objectives include conducting separate environmental monitoring and monitoring based on people's living environment and pollution sources. By monitoring pollution sources, people can find the root causes of environmental damage, thereby improving the cleanliness of the environment and achieving effective environmental management. Water quality monitoring requires the use of sampling devices to collect water samples, followed by testing, in order to monitor the water environment.

[0003] When sampling water sources, water environment monitoring sampling devices require sampling at different depths due to varying conditions. However, existing multi-layer sampling devices have a uniform distance between each sampling tube, limiting sampling to a fixed depth. When sampling at different depths is needed, multiple sampling depths are still required, resulting in low sampling efficiency. Therefore, those skilled in the art have provided a water environment monitoring sampling device for watershed management to address the problems mentioned in the background. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water environment monitoring and sampling device for watershed management. This device solves the problem that in existing multi-layer sampling equipment, the distance between each sampling tube is consistent, which means that sampling can only be performed on water sources at a fixed depth. When sampling water sources at different depths is required, multiple sampling operations are still necessary, resulting in low sampling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water environment monitoring and sampling device for watershed management, comprising a limiting rod, with fixing plates installed at both ends of the limiting rod, a connecting arm installed at one end of the fixing plate, a rotating shaft provided on one side of the limiting rod, a slot vertically engaged on the rotating shaft, a stepper motor driven and connected to the upper end of the rotating shaft, a rotating sleeve fitted on the rotating shaft, a retaining strip installed on the inner side of the rotating sleeve, a sealing plate installed on the outer side of the rotating sleeve, a sampling cylinder provided around the rotating sleeve, a liquid inlet hole opened on one side of the sampling cylinder, a fixing sleeve installed on the side of the sampling cylinder away from the liquid inlet hole, and a bolt threadedly connected to the fixing sleeve.

[0006] Preferably, the fixed sleeve is slidably sleeved with the limiting rod, one end of the bolt is in abutting contact with the limiting rod, the rotating sleeve is slidably sleeved with the rotating shaft, and the locking strip is slidably locked with the rotating shaft through the locking groove. The height of the sampling cylinder can be adjusted by adjusting the tightness of the bolt.

[0007] Preferably, the stepper motor is fixedly installed on the fixed plate, and the rotating shaft is rotatably sleeved with the fixed plate.

[0008] Preferably, the sampling cylinder has a through hole in the middle, and the rotating sleeve is rotatably connected to the sampling cylinder through the through hole. The sealing plate is attached to the inner wall of the sampling cylinder and blocks the liquid inlet. In the initial state, the sealing plate on the front side of the rotating sleeve, which is slidably engaged on the rotating shaft, blocks the liquid inlet. When the sampling cylinder reaches the water source at a specified depth, the stepper motor drives the rotating shaft to rotate. The rotating shaft rotates, and the rotating sleeve with the sealing plate rotates, so that the sealing plate and the liquid inlet are no longer sealed. The sampling cylinder begins to filter the liquid through the liquid inlet. When the liquid in the sampling cylinder is collected, the stepper motor drives the rotating shaft to rotate again, so that the sealing plate re-seals the liquid inlet, thereby completing the water source sampling.

[0009] Preferably, the upper side of the sampling tube is provided with an air hole, and a sealing plug is inserted into the air hole. A liquid outlet pipe is installed at the bottom of the sampling tube. When the connecting arm drives the device to rise through the lifting mechanism, the sealing plug can be pulled out, air enters through the air hole, and then the test tube is placed under the liquid outlet pipe. By opening the valve on the liquid outlet pipe, water can be collected.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The water environment monitoring sampling device is designed to consist of a connecting arm, a limiting rod, a rotating shaft, and a sampling cylinder. A slot is provided on the rotating shaft, and a rotating sleeve is fitted onto the shaft. The sampling cylinder is rotatably engaged with the rotating sleeve. A fixed sleeve is installed on one side of the sampling cylinder, and the fixed sleeve is slidably engaged with the limiting rod. A bolt is threaded onto one side of the fixed sleeve, with one end of the bolt pressing against the limiting rod. The height of the sampling cylinder can be adjusted by adjusting the tightness of the bolt. This allows the device to pre-adjust the height of the sampling cylinder when performing multi-level water source sampling, enabling sampling of water at the specified depths using the adjusted sampling cylinder.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution: a water environment monitoring and sampling device for watershed management. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 The system includes a limiting rod 3, with fixing plates 2 installed at both ends of the limiting rod 3. A connecting arm 1 is installed at one end of the fixing plate 2. A rotating shaft 5 is provided on one side of the limiting rod 3. A slot 6 is vertically engaged on the rotating shaft 5. A stepper motor 4 is driven and connected to the upper end of the rotating shaft 5. A rotating sleeve 15 is fitted on the rotating shaft 5. A retaining strip 16 is installed on the inner side of the rotating sleeve 15. A sealing plate 17 is installed on the outer side of the rotating sleeve 15. A sampling cylinder 7 is provided around the rotating sleeve 15. A liquid inlet hole 10 is opened on one side of the sampling cylinder 7. A fixing sleeve 8 is installed on the side of the sampling cylinder 7 away from the liquid inlet hole 10. A bolt 9 is threaded onto the fixing sleeve 8. The fixing sleeve 8 is slidably sleeved with the limiting rod 3. One end of the bolt 9 is in abutting contact with the limiting rod 3. The rotating sleeve 15 is slidably sleeved with the rotating shaft 5. The retaining strip 16 is slidably engaged with the rotating shaft 5 through the slot 6. The height of the sampling cylinder 7 can be adjusted by adjusting the tightness of the bolt 9.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4The stepper motor 4 is fixedly installed on the fixing plate 2, and the rotating shaft 5 is rotatably sleeved with the fixing plate 2. A through hole 14 is provided in the middle of the sampling cylinder 7, and the rotating sleeve 15 is rotatably sleeved with the sampling cylinder 7 through the through hole 14. The sealing plate 17 is fitted against the inner wall of the sampling cylinder 7, and the sealing plate 17 blocks the liquid inlet 10. In the initial state, the sealing plate 17 on the front side of the rotating sleeve 15, which is slidably engaged on the rotating shaft 5, blocks the liquid inlet 10. When the sampling cylinder 7 reaches a specified depth of water, the stepper motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 causes the rotating sleeve 15 with the sealing plate 17 to rotate, thus closing the seal between the sealing plate 17 and the liquid inlet 10. The sampling tube 7 is no longer sealed, and the liquid is filtered and fed into the sampling tube 7 through the liquid inlet 10. After the liquid in the sampling tube 7 is collected, the stepper motor 4 drives the rotating shaft 5 to rotate again, so that the sealing plate 17 re-seals the liquid inlet 10, thereby completing the sampling of the test tube. The upper side of the sampling tube 7 is provided with an air hole 12, and a sealing plug 13 is inserted into the air hole 12. The bottom of the sampling tube 7 is equipped with a liquid outlet pipe 11. When the connecting arm 1 lifts the device through the lifting mechanism, the sealing plug 13 can be pulled out, and air enters the air hole 12. Then, the test tube is placed under the liquid outlet pipe 11, and water can be collected by opening the valve on the liquid outlet pipe 11.

[0020] The water environment monitoring sampling device in this utility model consists of a connecting arm 1, a limiting rod 3, a rotating shaft 5, and a sampling cylinder 7. The connecting arm 1 is connected to the fixed plate 2 and can be connected to a telescopic mechanism for raising and lowering the sampling device.

[0021] Both ends of the limiting rod 3 are equipped with fixing plates 2. A rotating shaft 5 is provided on one side of the limiting rod 3, and a stepper motor 4 is driven and connected to the upper end of the rotating shaft 5. The stepper motor 4 is fixedly connected to the fixing plate 2 at the upper end of the limiting rod 3, and the rotating shaft 5 is rotatably inserted into the fixing plate 2. A slot 6 is provided on the rotating shaft 5, and a rotating sleeve 15 is fitted on the rotating shaft 5. The sampling cylinder 7 is rotatably engaged with the rotating sleeve 15. A fixing sleeve 8 is installed on one side of the sampling cylinder 7, and the fixing sleeve 8 is slidably sleeved with the limiting rod 3. A bolt 9 is threadedly connected to one side of the fixing sleeve 8. One end of the bolt 9 is pressed into contact with the limiting rod 3. The height of the sampling cylinder 7 can be adjusted by adjusting the tightness of the bolt 9. Thus, when the device performs multi-level test tube sampling, the height of the sampling cylinder 7 can be pre-adjusted. Then, when performing multi-level sampling of water sources, the water source at the specified depth can be sampled through the adjusted sampling cylinder 7.

[0022] Furthermore, after the sampling cylinder 7 enters the water source, in the initial state, the sealing plate 17 on the front side of the rotating sleeve 15, which is slidably engaged on the rotating shaft 5, seals the liquid inlet hole 10. When the sampling cylinder 7 reaches the water source at the specified depth, the stepper motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 rotates, and the rotating sleeve 15 with the sealing plate 17 rotates, so that the sealing plate 17 and the liquid inlet hole 10 are no longer sealed. The sampling cylinder 7 begins to filter the liquid through the liquid inlet hole 10. When the liquid in the sampling cylinder 7 is collected, the stepper motor 4 drives the rotating shaft 5 to rotate again, so that the sealing plate 17 re-seals the liquid inlet hole 10, thereby completing the sampling of the water source.

[0023] When the connecting arm 1 lifts the device via the lifting mechanism, the sealing plug 13 can be pulled out to collect water samples from the sampling tube 7, allowing air to enter through the vent 12. Then, the test tube is placed under the outlet tube 11, and the water can be collected by opening the valve on the outlet tube 11.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
