Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, and in particular to a remotely controllable water sampling device. Background Technology

[0002] Water samples for analyzing the chemical composition of natural river water are generally taken 0.2–0.5 meters below the surface of the phreatic channel at the hydrological station's flow measurement section. When the section is open, more sampling points should be added. Bank sampling points must be located in areas with unobstructed water flow. If necessary, stratified sampling at different depths can also be conducted. The number of sampling sessions should be evenly distributed across different periods and flow rates according to water condition changes. Measurements should be taken during the high-water, normal-water, and low-water periods. For rivers where flood runoff accounts for a large proportion of the annual runoff, sampling should be increased during the flood season. For small flood peaks, samples should be taken from the peak; for large flood peaks, samples should be taken from the rising water level, the peak, and the receding water level. When conducting river water quality field surveys, samples should be taken along the main stream of a straight river channel. Otherwise, samples should be taken as far away from the bank as possible, at locations with high flow velocities, and remotely controlled sampling devices should be used.

[0003] Patent No. 201910888625.9 discloses a remote-controlled water sampling device for rivers or lakes, relating to the field of water quality monitoring. It includes a remote-controlled boat and multiple sampling bottles. A support base is mounted on the remote-controlled boat, and a rotating shaft is rotatably connected to the support base. A first motor is mounted on the remote-controlled boat to drive the rotating shaft. Multiple winches, the same number as the sampling bottles, are spaced at intervals on the rotating shaft, with the diameter of the winches increasing in an ascending order. Hinged ropes are wound around the winches, and pulleys are provided on the remote-controlled boat for the winches to pass over. Each sampling bottle has a cap, and the winches are fixed to the center of the cap. The cap has multiple water inlets, and a switch on the lower end of the cap controls the opening and closing of the water inlets. However, it has the following drawbacks: When the remote-controlled water sampling device in the application is in use, the water inlet is prone to mixing with water from different water layers when the device is retracted upwards after sampling, resulting in inaccurate water detection data. Therefore, we propose a remotely controllable water sampling device. Summary of the Invention

[0004] The purpose of this invention is to provide a remotely controllable water sampling device to solve the problems mentioned in the background art.

[0005] To solve, or at least partially solve, the aforementioned technical problems, this utility model provides a remotely controllable water sampling device, comprising: a remotely controlled small boat and a water sampling mechanism. The feature is that the right side of the remote-controlled boat has a through-hole, and a water-collecting mechanism is movably inserted into the inside of the hole. The upper middle part of the water-collecting mechanism is wrapped around the outside of a retractable shaft that can rotate and retract the retractable rope by a pull rope. The water sampling mechanism is shaped like a frustum. A counterweight is fixedly connected to the bottom of the water sampling mechanism. The upper and lower sides of the water sampling mechanism are respectively provided with a water intake chamber and a sealing connection chamber. A piston plate is movably sealed inside the water intake chamber. A sealing rubber ring is fixed to the inner wall of the water intake chamber on the outer side of the piston plate. The piston plate can move up and down along the inner side of the sealing rubber ring. An electric telescopic rod is fixedly installed in the middle of the inner cavity of the sealed connection cavity, and the upper end of the transmission rod of the electric telescopic rod is fixedly connected to the lower middle of the piston plate.

[0006] Optionally, the upper end of the water intake chamber is evenly provided with several connecting holes, and the lower outer wall of the frustum-shaped water intake mechanism is provided with a water intake hole that penetrates the bottom of the water intake chamber. The outer side of the water intake hole is used to take water, and the water taken enters the bottom of the piston plate through the inner side of the water intake hole. The water entering the bottom of the piston plate can flow continuously to the bottom of the water intake chamber as the piston plate moves up.

[0007] Optionally, a temperature sensor is fixedly installed in the lower part of the inner cavity of the water intake chamber, and the temperature sensor is connected to the first wireless transmission controller via a wire.

[0008] Optionally, the first wireless transmission controller is fixedly connected to the inner cavity of the sealed connection cavity, and a first rechargeable power supply is fixedly connected to the outer side of the inner cavity of the sealed connection cavity. The first rechargeable power supply provides working power for the temperature sensor, the first wireless transmission controller and the motor that drives the electric telescopic rod. The first wireless transmission controller also controls the electric telescopic rod to perform telescopic movements.

[0009] Optionally, the water sampling mechanism has a measuring range on the outer wall at the front end of the water intake chamber for observing the amount of water in the water intake chamber.

[0010] Optionally, a bracket is fixedly connected to the upper right side of the remote-controlled boat, and ear plates are symmetrically fixedly connected to the upper end of the bracket. A retraction shaft is rotatably provided between the ear plates, and the front end of the retraction shaft is fixedly connected to the motor shaft of a transmission motor fixed on the outside of the ear plates.

[0011] Optionally, the remote-controlled boat has a connecting cavity on the left side of its interior, and a second wireless transmission controller and a second rechargeable power supply are fixedly installed inside the connecting cavity. A sealing cover is sealed to the upper end of the connecting cavity, and the second wireless transmission controller controls the connected drive motor.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art: The device provided by this utility model involves placing a remote-controlled boat on the surface of the area where water needs to be collected. A person on the shore can control the boat to the designated water-collecting location using a remote control. Then, the remote control drives a transmission motor to rotate the release shaft, releasing the pull rope. Due to gravity, the water-collecting mechanism will displace. Once the desired depth is reached, the remote control stops the transmission motor. The remote control then activates an electric telescopic rod, which moves the piston plate upwards. Due to the action of the piston plate and the sealing rubber ring, water is drawn from outside through the water intake hole into the water-collecting chamber below the piston plate until the piston plate reaches the desired depth. At the top of the water chamber, the piston plate stops moving upwards when the handheld remote control is activated, completing the water collection process. This makes the water collection operation of the water collection mechanism more convenient. Afterwards, the control motor reverses to drive the take-up and release shaft to rotate, thus retracting the pull rope until the water collection mechanism is positioned inside the frustum-shaped hole. The handheld remote control then stops the drive motor. This invention makes water collection more convenient and allows for sampling of water at different depths. Furthermore, the vertical movement of the piston plate during water collection creates a sealed structure in the space below the piston plate within the water collection chamber after collection, preventing external water from entering the lower part of the chamber. This makes the water collection more stable and avoids mixing between the inlet and water at different depths. Attached Figure Description

[0022] like Figures 1-4 As shown, this embodiment of the utility model provides a remotely controllable water sampling device, including: a remote-controlled boat 1 and a water sampling mechanism 4. The feature is that a frustum hole 8 is opened through the right side of the remote-controlled boat 1, and a water collection mechanism 4 is movably inserted into the frustum hole 8. The upper middle part of the water collection mechanism 4 is wrapped around the outside of the retractable shaft 5 that can rotate and retract the retractable rope by a pull rope 6. The water sampling mechanism 4 is shaped like a frustum. A counterweight 16 is fixedly connected to the bottom of the water sampling mechanism 4. The upper and lower sides of the water sampling mechanism 4 are respectively provided with a water intake cavity 10 and a sealing connection cavity 17. The bottom of the water intake cavity 10 is connected to the top of the sealing connection cavity 17. The water intake cavity 10 is used to take water, and the sealing connection cavity 17 is used to fix the electric telescopic rod and to seal and fix the first wireless transmission controller and the first rechargeable power supply. The water intake cavity 10 is movably sealed with a piston plate 11, and a sealing rubber ring 12 is fixed to the inner wall of the water intake cavity 10 on the outer side of the piston plate 11. The piston plate 11 can move up and down along the inner side of the sealing rubber ring 12. An electric telescopic rod 14 is fixedly installed in the middle of the inner cavity of the sealed connection cavity 17, and the upper end of the transmission rod of the electric telescopic rod 14 is fixedly connected to the lower middle of the piston plate 11.

[0023] Specifically: The remote-controlled boat 1 adopts an existing remote-controlled boat on the market, which is existing technology and can be controlled by a handheld remote control.

[0024] like Figure 1 As shown, the upper end of the water intake cavity 10 is evenly provided with a plurality of connecting holes 9. The number of connecting holes 9 is determined as needed, for example, 5-20. The lower outer wall of the frustum-shaped water collection mechanism 4 is provided with a water intake hole 18 that penetrates the bottom of the water intake cavity 10. The outer side of the water intake hole 18 is used for water intake. The water intake enters the bottom of the piston plate 11 through the inner side of the water intake hole 18. The water entering the bottom of the piston plate 11 can continuously flow to the bottom of the water intake cavity 10 as the piston plate 11 moves upward. When the piston plate 11 moves to the required depth, the required amount of water is flushed into the water intake cavity 10. This amount of water can be obtained from the water intake cavity 10 through a device set on the front outer wall of the water intake cavity 10. As can be seen from range 19, the first wireless transmission controller can control the motor connected to the electric telescopic rod 14 to work. The motor works and drives the electric telescopic rod 14 to move up and down. The up and down movement of the electric telescopic rod 14 can drive the connected piston plate 11 to move up and down, so that the piston plate 11 can move up and down along the inner side of the sealing rubber ring 12. The connecting holes 9 evenly opened on the upper end face of the water intake chamber 10 can make the piston plate 11 move upward. The water intake hole 18 can draw water located outside the water intake mechanism 4 when the piston plate 11 moves upward, and when the piston plate 11 moves downward, it can gradually discharge the water inside the water intake chamber 10.

[0025] like Figure 2 and Figure 4 As shown, a temperature sensor 13 is fixedly installed in the lower part of the inner cavity of the water intake chamber 10. The temperature sensor 13 is connected to the first wireless transmission controller via a wire. The temperature sensor 13 can detect the water temperature in the inner cavity of the water intake chamber 10 and display it on a handheld remote control wirelessly connected to the first wireless transmission controller via a wireless network. The handheld remote control can control the motor through the first wireless transmission controller and extend and retract the electric telescopic rod 14 connected to the motor to control the amount of water taken from the water intake chamber 10. The handheld remote control is a technology that can be implemented by general technicians and can be used to control the remote-controlled boat 1.

[0026] The first wireless transmission controller is fixedly connected to the inner cavity of the sealed connection cavity 17. A first rechargeable power supply 15 is fixedly connected to the outer side of the inner cavity of the sealed connection cavity 17. The first rechargeable power supply 15 provides operating power to the temperature sensor 13, the first wireless transmission controller, and the motor driving the electric telescopic rod 14. The first wireless transmission controller also controls the motor of the electric telescopic rod 14 and performs telescopic movements through the electric telescopic rod 14. The electric telescopic rod 14 can be a commercially available electric actuator, such as the electric actuator produced by Yangzhou Jiafeng Hydraulic Complete Equipment Co., Ltd. The electric actuator is a new type of linear actuator mainly composed of a motor, actuator, and control device, enabling remote and centralized control. The electric actuator reciprocates within a certain range of stroke. The standard stroke of a typical electric actuator is 100, 150, 200, 250, 300, 350, or 400 mm. Special strokes can also be designed and customized according to different application requirements.

[0027] Specifically: the temperature sensor 13, the first wireless transmission controller, the first rechargeable power supply 15, and the electric telescopic rod 14 all utilize existing equipment and technologies on the market. The first wireless transmission controller adopts the controller found in existing remote-controlled boats, such as the overall controller structure of the remote-controlled baiting boat from the Leading brand. The temperature sensor 13 can detect the temperature of the water in the intake layer. The first rechargeable power supply 15 provides operating power to the temperature sensor 13, the first wireless transmission controller, and the motor driving the electric telescopic rod 14. The first wireless transmission controller also controls the electric telescopic rod 14 to perform telescopic movements, causing the piston plate 11 to move up and down. The preferred function of the first wireless transmission controller is to wirelessly connect with a person on the shore holding a remote control and control the electric... The motor in the telescopic rod 14 starts or stops, i.e., the motor is energized or de-energized. When a person on the shore uses the remote control to activate the upward movement button of the electric telescopic rod, the motor in the electric telescopic rod 14 is energized by the first rechargeable power supply 15, the motor in the electric telescopic rod 14 starts, and the electric telescopic rod 14 moves upward, allowing the water intake chamber 10 to take water. When a person on the shore uses the remote control to activate the downward movement button of the electric telescopic rod, the motor in the electric telescopic rod 14 is energized by the first rechargeable power supply 15, the motor in the electric telescopic rod 14 starts, the electric telescopic rod 14 moves downward, and the water intake chamber 10 drains water. When a person on the shore uses the remote control to close the electric telescopic rod button, the first rechargeable power supply 15 does not supply power to the electric telescopic rod 14, and the electric telescopic rod stops extending or retracting.

[0028] like Figure 1 As shown, the water sampling mechanism 4 is provided with a measuring range 19 on the outer wall at the front end of the water intake chamber 10 for observing the water volume in the water intake chamber 10; specifically, the water volume in the water intake chamber 10 can be seen through the measuring range 19 from the outer wall of the water sampling mechanism 4.

[0029] like Figure 1 As shown, a bracket 3 is fixedly connected to the upper right side of the remote-controlled boat 1. Ear plates are symmetrically fixedly connected to the upper end of the bracket 3, and a retraction shaft 5 is rotatably provided between the ear plates. The front end of the retraction shaft 5 is fixedly connected to the motor shaft of the transmission motor 7 fixed on the outside of the ear plates.

[0030] Specifically: The drive motor 7 drives the take-up and release shaft 5 to rotate in both directions via the motor shaft, thereby causing the take-up and release shaft 5 to take up or release the wire.

[0031] like Figure 1 As shown, the remote-controlled boat 1 has a connecting cavity on the left side inside, and a second wireless transmission controller and a second rechargeable power supply are fixedly installed inside the connecting cavity. A sealing cover plate 2 is sealed to the upper end of the connecting cavity, and the second wireless transmission controller controls the connected drive motor 7.

[0032] Specifically: the second wireless transmission controller, the second rechargeable power supply, and the drive motor 7 all utilize existing equipment and technology on the market. The second wireless transmission controller adopts the controller structure found in existing remote-controlled boats, such as the motor remote control controller structure of the Leading Path brand remote-controlled baiting boat. The drive motor 7 can rotate in both directions. Specifically, when a person on the shore uses a remote control to activate the forward rotation button of the drive motor 7, the remote control wirelessly connects to the second wireless transmission controller, which then activates the second rechargeable power supply to power the forward rotation of the drive motor 7. The forward rotation of the drive motor 7 drives the reel-in shaft 5 to rotate in the same direction, thus releasing the line 6 through water sampling. Under the influence of the counterweight at the bottom of mechanism 4, the water sampling mechanism 4 will move downwards. When it reaches the required depth, a person on the shore can press the stop button on the drive motor using a remote control, and the drive motor 7 will stop working. When the person on the shore uses the remote control to activate the reverse button on the drive motor 7, the remote control is wirelessly connected to the second wireless transmission controller, and the second wireless transmission controller activates the second rechargeable power supply to power the reverse rotation of the drive motor 7. The reverse rotation of the drive motor 7 drives the retractor shaft 5 to rotate in reverse, thereby retracting the pull rope 6 until the water sampling mechanism 4 moves into the interior of the frustum hole 8. At this point, the person on the shore can press the stop button on the drive motor using a remote control, and the drive motor 7 will stop rotating.

[0033] Principle: In use, the remote-controlled boat 1 is placed on the surface of the area where water needs to be collected. A person on the shore can use a remote control to move the boat to the designated water collection location. Then, the remote control is used to control the second wireless transmission controller, which in turn controls the drive motor 7 to rotate the retractor shaft 5, releasing the pull rope 6. Due to the weight of the counterweight at the bottom of the water collection mechanism 4, the mechanism 4 will move downwards. Once the desired depth is reached, the person on the shore can press the stop button on the drive motor using the remote control, stopping the drive motor 7. Then, the electric telescopic mechanism is activated via the first wireless transmission controller. The rod 14 causes the piston plate 11 to move upward. Due to the tight action between the piston plate 11 and the sealing rubber ring 12, when the piston plate 11 moves upward, it draws water from the outside through the water intake hole 18 into the water intake chamber 10 located in the space below the piston plate 11. As the piston plate 11 moves upward until it reaches the upper part of the water intake chamber 10, the water intake chamber 10 obtains the required amount of water, and the water intake is completed. Then, the drive motor 7 is reversed to drive the retracting shaft 5 to rotate, and the pull rope 6 is retracted until the water intake mechanism 4 moves into the frustum hole 8. The remote control is then used to move the remote-controlled boat 1 to the shore, and the remote-controlled boat 1 can be taken away.

[0034] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
