Description

Technical Field

[0001] The utility model relates to the technical field of hydrological collection, in particular to a universal hydrological collection terminal. Background Art

[0002] Hydrological information refers to various data that describe the status and changes of water bodies, including water level, flow, water temperature, water quality, etc. This information plays a vital role in water resources management, environmental protection, disaster warning and other fields. By accurately and timely collecting and analyzing hydrological information, it can provide relevant departments with a basis for scientific decision-making and effectively respond to challenges such as water resource shortages, water pollution, and floods.

[0003] Traditional hydrological data collection methods are highly dependent on manual operations, which not only leads to a large consumption of resources, including human resources, materials and equipment, and time costs, but also affects the accuracy and reliability of the data due to human factors such as operational errors, subjective judgment bias, and fatigue, especially in harsh environmental conditions. In addition, manual diving operations to install or recover hydrological data collection devices not only greatly increase the safety risks of workers, but also limit the scope and frequency of data collection operations, thereby limiting the frequency and coverage of hydrological data collection. Therefore, although traditional hydrological data collection methods have met the basic hydrological monitoring needs to a certain extent, their limitations have become increasingly apparent. There is an urgent need to explore and apply more advanced and intelligent hydrological data collection technologies to improve monitoring efficiency, accuracy, and safety.

[0004] Chinese patent document CN217033156U discloses a sampling device for hydrological data collection, including a sampling bucket, a fixing member provided on both sides of the sampling bucket, a circular hole provided inside the sampling bucket, a plurality of circular holes provided, a sampling reagent tube movably connected to the plurality of circular holes, and a filtering mechanism and an adjusting mechanism provided on the top of the sampling bucket. However, the following defects still exist during implementation:

[0005] Although the device in the above document can filter and block garbage or debris in the river through the filter cover during sampling to prevent it from entering the sampling reagent tube together with the river water, the device in the above document can only sample one height position in the river at a time, and the sampling efficiency is low. Utility Model Content

[0006] The purpose of the present invention is to provide a universal hydrological data collection terminal to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A universal hydrological collection terminal comprises a connecting frame, a lifting assembly, several boxes and several box covers; the lower part of the connecting frame is fixedly connected to one of the boxes, a flow rate sensor is provided on one side of the lower part of the connecting frame, and the flow rate sensor is used to sense the flow rate of river water; the lower ends of the several boxes are symmetrically fixedly connected with connecting blocks, the upper parts of the box covers are symmetrically fixedly connected with several limit assemblies, the upper parts of the box covers are symmetrically provided with slide grooves, the inner cavities of the slide grooves are slidably connected to adjacent connecting blocks, the upper parts of the boxes are symmetrically provided with card slots, the inner cavities of the card slots are card-connected to the lower parts of adjacent box covers, a partition assembly is provided on one side of the box, the partition assembly is used to filter the sampled river water, the inner cavity of the box is fixedly connected with a connecting plate, and several sampling test tubes are placed in the middle of the connecting plate.

[0009] The above-mentioned technical solution is adopted. In this solution, the device can be driven to rise and fall through the cooperation of the lifting assembly and the connecting frame, thereby eliminating the need for manual diving operations to install or recover the device. By symmetrically fixing the connecting blocks at the lower end of the box body, and then slidingly connecting the connecting blocks with the adjacent slide cavities, several boxes and several box covers can be connected to form a whole. Then, during the sampling process, the timing of the river water entering the box cavity is controlled by the partition assembly, so that layered sampling of river water at different heights at the same position of the river can be achieved, thereby improving the sampling efficiency, and being able to analyze samples of river water at different positions and heights, thereby improving the detection quality.

[0010] A further improvement of the technical solution of the present utility model is that: the partition assembly includes a support block, the support block is fixedly connected to the box body, the inner cavity of the support block is symmetrically fixedly connected with an electric push rod, the output ends of the two electric push rod telescopic rods are commonly fixedly connected with a baffle, the baffle is slidably connected to the inner cavity of the support block, and a filter screen is provided on the upper part of the support block.

[0011] The above-mentioned technical solution is adopted. In this solution, a filter screen is provided on the upper part of the support block, so that the filter screen can be used to filter the river water entering the inner cavity of the box, thereby preventing some garbage or debris in the river from entering the sampling test tube together with the river water, thereby affecting the detection of the river water. The output end of the telescopic rod of the electric push rod is fixedly connected to the baffle, so that the baffle can be driven to rise and fall by the electric push rod, and then the obstruction of the filter screen can be released as needed, thereby preventing the river water from freely entering the inner cavity of the box.

[0012] A further improvement of the technical solution of the present utility model is that: a clamping plate is symmetrically fixedly connected to the lower part of the box cover, both clamping plates are symmetrically provided with threaded holes, and the outer surface of the clamping plate on the same side is clamped with the inner cavity of the clamping slot.

[0013] The above technical solution is adopted. In this solution, the box body and the box cover can be connected together by clamping the inner cavity of the card slot with the outer surface of the card plate, thereby forming a closed space in the inner cavity of the box, which can improve the sampling accuracy of the device and enable the device to accurately collect river water samples of the target depth, thereby ensuring the purity and representativeness of the sample. By symmetrically opening threaded holes on the card plate and then using bolts to cooperate with the threaded holes, the threaded holes can be fixed to the box body, thereby further improving the sealing and stability of the connection between the box body and the box cover.

[0014] A further improvement of the technical solution of the present utility model is that: the connecting plate is supported by a rubber material, a plurality of water outlet holes are opened on the connecting plate, a one-way valve is fixedly connected to the lower part of the box body, the bottom wall of the inner cavity of the box body is arranged at an angle, and the horizontal height of the side of the bottom wall of the inner cavity of the box body away from the one-way valve is higher than the side of the bottom wall of the inner cavity of the box body close to the one-way valve.

[0015] The above technical solution is adopted. In this solution, since the connecting plate is made of rubber material, it can protect several sampling test tubes when using the connecting plate to support and limit them. When the device is sampling river water, the fluidity of the river water will cause the device to shake in the water. The connecting plate can absorb the impact caused by the shaking and reduce damage to the sampling test tubes. By opening a plurality of water outlet holes on the connecting plate, water can be discharged toward the lower part of the inner cavity of the box through the plurality of water outlet holes, and then the excess river water is discharged from the inner cavity of the box through the one-way valve. When the device is stretched up, the weight of the device can be reduced. By setting the bottom wall of the inner cavity of the box at an angle, the flow rate of the water can be accelerated, making the drainage process faster and more efficient.

[0016] A further improvement of the technical solution of the present invention is that the connecting block is T-shaped, and a limiting groove is provided on one side of the connecting block close to the limiting assembly.

[0017] The above-mentioned technical solution is adopted. In this solution, by setting the connecting block to a T-shape, it can provide higher stability when the connecting block moves. The larger contact area can disperse the load and reduce the shaking caused by vibration or external force, ensuring that the connecting block remains stable during movement. By opening a limiting groove on the side of the connecting block close to the limiting component, it is possible to facilitate the cooperation between the limiting component and the limiting groove, thereby limiting the position of the connecting block in the inner cavity of the slide groove.

[0018] A further improvement of the technical solution of the present utility model is that the lifting assembly includes two support frames, the opposite surfaces of the two support frames are connected to two shafts for common rotation, a rope is provided on the outer surface of the shaft, and one end of the rope is fixedly connected to the upper end of the connecting frame.

[0019] The above technical solution is adopted. In this solution, the shaft is driven to rotate by a motor, and then the shaft can be used to drive the rope to be raised and lowered, and then the partition assembly can be raised and lowered together, thereby saving the physical strength of the workers.

[0020] A further improvement of the technical solution of the present utility model is that: the limit assembly includes an electromagnet, a shell and a spring, the inner cavity of the shell is fixedly connected to the electromagnet, the outer surface of the shell is fixedly connected to the box cover, the inner cavity of the shell on the same side is communicated with the inner cavity of the slide groove, a connecting rod is fixedly connected to the middle part of the electromagnet, an iron rod is slidably connected to the side of the inner cavity of the shell away from the electromagnet, one end of the spring is fixedly connected to the iron rod, and the other end of the spring is fixedly connected to the electromagnet.

[0021] The above technical solution is adopted. In this solution, by energizing the electromagnet, magnetic force can be generated, which can then drive the iron rod to move toward the electromagnet, and then drive the iron rod to disengage from the adjacent limit groove cavity, and then release the position limit of the connecting block.

[0022] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0023] 1. The utility model provides a universal hydrological collection terminal. Through the cooperation of the lifting component and the connecting frame, the device can be driven to rise and fall, thereby eliminating the need for manual diving operations to install or recover the device, reducing the efficiency of human resources, reducing the safety risks of staff, and improving the scope and frequency of collection operations. By symmetrically fixing the connecting blocks at the lower end of the box body, and then slidingly connecting the connecting blocks with the adjacent slide cavities, a number of boxes and a number of box covers can be connected to form a whole. Then, during the sampling process, the timing of the river water entering the box cavity is controlled by the partition assembly, so that stratified sampling of river water at different heights at the same position of the river can be achieved, thereby improving the sampling efficiency, and being able to analyze samples at different heights of the river water, thereby improving the detection quality, thereby improving the practicality and universality of the device.

[0024] 2. The utility model provides a universal hydrological collection terminal. A filter screen is provided on the upper part of the support block, so that the filter screen can be used to filter the river water entering the inner cavity of the box, so that some garbage or debris in the river can be prevented from entering the sampling test tube together with the river water, thereby affecting the detection of the river water. The output end of the telescopic rod of the electric push rod is fixedly connected to the baffle, so that the baffle can be driven to rise and fall by the electric push rod, and then the obstruction of the filter screen can be released as needed, so that the river water can be prevented from freely entering the inner cavity of the box. The inner cavity of the card slot is clamped with the outer surface of the card plate, so that the box body and the box cover can be connected together, thereby forming a closed space in the inner cavity of the box, which can improve the sampling accuracy of the device and enable the device to accurately collect river water samples of the target depth, thereby ensuring the purity and representativeness of the sample. By symmetrically opening threaded holes on the card plate, the threaded holes can be fixed to the box body by using bolts to cooperate with the threaded holes, thereby further improving the sealing and stability of the connection between the box body and the box cover.
