Description

Technical Field

[0001] This utility model relates to the field of hydrology, and in particular to a sampling device for a hydrological telemetry station. Background Technology

[0002] A water level telemetry station refers to a station that monitors various parameters of a body of water in real time by installing cameras, rain gauges, and level gauges near the water body under wireless transmission conditions. The data is then transmitted to relevant departments via a wireless transmission module, allowing staff to assess water level trends.

[0003] When water becomes turbid, flash floods occur, or torrential rains occur, staff cannot personally go to collect water samples in a timely manner due to climate influences, environmental limitations, or distance constraints. Current technologies also lack equipment for timely water sample collection during specific water conditions, and cannot perform time-segmented sampling of specific water areas in the early, middle, and late stages, making it difficult to guarantee the real-time nature and accuracy of the data. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for hydrological telemetry stations, which aims to solve the problem that existing technologies cannot collect water samples in a timely manner for specific hydrological conditions.

[0005] The purpose of this utility model is achieved through the following technical solution: a rotating shaft is included, a traction belt is wound around the rotating shaft, a sampling tube is fixedly connected to the end of the traction belt away from the rotating shaft, an inner tube is rotatably installed inside the sampling tube, the inner tube is coaxial with the sampling tube, and the outer wall of the inner tube is in contact with the inner wall of the sampling tube, a motor is installed on the end face of the sampling tube, and the output shaft of the motor extends into the sampling tube and is poweredly connected to the inner tube;

[0006] The sampling cylinder has a water inlet hole on its outer circumference. The inner cylinder has at least two storage cavities evenly distributed around its axis. Each storage cavity has a through hole on its side wall that connects to the outside. The height of each through hole corresponds to that of the water inlet hole.

[0007] The beneficial effects of this utility model are: the traction belt can drive the sampling tube to rise and fall, adjust the height, and is suitable for different water heights; the inner tube can connect different storage chambers with the water inlet by rotation, and can be remotely controlled to achieve time-sharing sampling for different water conditions.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the rotating shaft is fitted with a housing, on which a drive motor is mounted. The output shaft of the drive motor extends into the housing and is poweredly connected to the rotating shaft.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the outer casing protects the shaft and traction belt, and the drive motor provides power to the shaft.

[0011] Furthermore, a connecting plate is fixedly provided on the outer wall of the outer shell.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the connecting plate can be better connected and fixed to the mounting frame of the hydrological telemetry station.

[0013] Furthermore, the sampling tube includes a tube body and a detachable cover, and the end of the traction belt away from the rotating shaft is fixedly connected to the cover of the sampling tube.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the sampling tube can be opened after the collection is completed, making it convenient to replace the inner tube and take out the water sample. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1

[0024] like Figures 1 to 4As shown, a sampling device for a hydrological telemetry station includes a rotating shaft 1, a traction belt 2 wound around the rotating shaft 1, a sampling cylinder 3 fixedly connected to the end of the traction belt 2 away from the rotating shaft 1, an inner cylinder 4 rotatably installed inside the sampling cylinder 3, the inner cylinder 4 being coaxial with the sampling cylinder 3, and the outer wall of the inner cylinder 4 being in contact with the inner wall of the sampling cylinder 3, and a motor 5 being installed on the end face of the sampling cylinder 3, the output shaft of the motor 5 extending into the sampling cylinder 3 and being poweredly connected to the inner cylinder 4;

[0025] The sampling cylinder 3 has a water inlet hole 6 on its outer circumference. The inner cylinder 4 has at least two storage cavities 7 evenly distributed around its axis. The side walls of the storage cavities 7 are provided with through holes 8 that connect to the outside. The height of each through hole 8 corresponds to that of the water inlet hole 6.

[0026] A hydrological telemetry station is a 7-shaped support installed next to bodies of water such as rivers, lakes, reservoirs, canals, and groundwater. One end of the 7-shaped support extends directly above the water body and is equipped with electronic devices such as cameras and radar level gauges. An electrical box is installed below the 7-shaped support, which contains a PLC, a data storage module, and a wireless transmission module. The electronic devices transmit data to the data storage module, and the data storage module and wireless transmission module aggregate the data and transmit it remotely to relevant departments to achieve hydrological telemetry.

[0027] In this embodiment, the rotating shaft 1 is horizontally fixed on the top of the 7-shaped bracket, and the traction belt 2 and the sampling tube 3 are lowered into the water. The traction belt 2 is a flat belt (with high corrosion resistance and wear resistance, and is not easily corroded or damaged by water). In the initial state, the through holes 8 of all storage chambers 7 are staggered from the water inlet holes 6, and the outer wall of the inner cylinder 4 is in contact with the inner wall of the sampling tube 3. The storage chambers 7 are not connected to the outside world and are in a closed state.

[0028] When water conditions change, such as when the water becomes turbid, or when there is a flash flood or heavy rain, staff may not be able to go to the site in person due to severe weather, distance, or environmental limitations. The duration of the water condition change can be divided into early, middle, and late stages. Staff can remotely control the motor 5 to rotate, which will drive the inner cylinder 4 to rotate and rotate any storage chamber 7 to the direction of the water inlet 6. The through hole 8 of the storage chamber 7 is connected to the water inlet 6, and the water sample enters the storage chamber 7. Then the inner cylinder 4 continues to rotate, and the storage chamber 7 is closed again.

[0029] After a predetermined period of time, another storage chamber 7 is rotated to the direction of the water inlet 6 to collect water samples multiple times. Finally, staff go to the site to retrieve the water samples and conduct tests and evaluations on the different water samples from the early, middle and late stages of the water situation to determine the water condition and make backups, which can serve as a reference for the next water situation change.

[0030] In addition, the rotation of motor 5 can be automatically controlled by sensors by timing the PLC in advance, reducing human error.

[0031] Based on this embodiment, the top surface of the inner cylinder 4 can be closed or open, and the output shaft of the motor 5 is poweredly connected to the center of the inner cylinder 4; the overall height of the sampling cylinder 3 and the inner cylinder 4 is 12cm, and the height of the center of the through hole 8 and the water inlet hole 6 is more than 8cm, ensuring that when the inner cylinder 4 is taken out from the sampling cylinder 3, even if some water sample flows out from the through hole 8, the storage cavity 7 below the through hole 8 still has enough volume to accommodate the water sample.

[0032] Example 2

[0033] like Figures 1 to 2 As shown, preferably, based on Embodiment 1, the rotating shaft 1 is fitted with a housing 9, and a drive motor 10 is mounted on the housing 9. The output shaft of the drive motor 10 extends into the housing 9 and is poweredly connected to the rotating shaft 1.

[0034] Preferably, a connecting plate 11 is fixedly provided on the outer wall of the outer shell 9.

[0035] In this embodiment, the outer shell 9 is used to protect the rotating shaft 1. The rotating shaft 1 rotates inside the outer shell 9. The drive motor 10 controls the rotation of the rotating shaft 1 to roll up or release the traction belt 2. The connecting plate 11 is used to fix the outer shell 9 on the 7-shaped bracket of the hydrological telemetry station, which is convenient for disassembly and assembly.

[0036] Example 3

[0037] like Figure 3 As shown, preferably, based on embodiments 1-2, the sampling tube 3 includes a tube body 301 and a detachable cover 302, and the end of the traction belt 2 away from the rotating shaft 1 is fixedly connected to the cover 302 of the sampling tube 3.

[0038] In this embodiment, the inner cylinder 4 rotates inside the sampling cylinder 3, and the cover 302 is fixed to the cylinder 301 by screws. After sampling is completed, the cover 302 is opened to remove the inner cylinder 4, which facilitates the replacement of the inner cylinder 4 and the removal of the water sample.

[0039] In addition, a U-shaped connecting hook 303 is fixedly installed on the top surface of the cover 302, and a pin is fixedly provided at the end of the traction belt 2. The two ends of the pin are rotatably connected to the two sides of the connecting hook 303 to ensure that the sampling tube 3 has a high degree of freedom.

[0040] Based on this embodiment, a sealing ring is installed on the mating surface of the cover 302 and the cylinder 301 to improve the sealing performance.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
