Description

Technical Field

[0001] This utility model relates to a water sampling device, specifically a water body detection sampling device, belonging to the field of water body detection technology. Background Technology

[0002] Water quality monitoring is the process of monitoring and determining the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The scope of water quality monitoring is very broad, including routine surface and groundwater monitoring, surveillance of production and domestic processes, and emergency accident monitoring.

[0003] The utility model patent CN221594402U discloses a sampling tube for monitoring water bodies in environmental protection, which relates to the field of water body monitoring and sampling technology. The side end of the annular plate is fixedly connected to a side plate. In this utility model, by rotating the rotating head, the cleaning plate can be driven to rotate. At this time, the cleaning plate can scrape the impurities on the top of the filter plate to one side, thus clearing the filter plate and making it easier for the water to continue to be filtered into the measuring cup.

[0004] When sampling water bodies for testing, it is necessary to sample and test the water quality at different depths and locations. Although the sampling device in the aforementioned patent avoids impurities from interfering with water quality testing, it requires the use of multiple sampling tubes to sample water at different locations, increasing the number of sampling tubes. Furthermore, too many sampling tubes can increase the difficulty of sample preservation, recording, and classification, making water testing more cumbersome. Therefore, we have provided a water testing sampling device to solve the above problems. Utility Model Content

[0006] This utility model is achieved through the following technical solution: a water body detection sampling device.

[0007] The device includes a sealing cylinder and a fixed cover. The sealing cylinder has a sampling mechanism inside, which includes a rotating disk, a positioning plate, and a sampling tube. The two ends of the sampling tube are fixedly connected to the rotating disk and the positioning plate, respectively. A sliding piston is slidably connected inside the sampling tube. A push plate is fixedly connected to the top of the sliding piston. The bottom of the fixed cover has a filtering mechanism, which includes a rubber ring and a filter screen. The rubber ring is fixedly connected to the fixed cover.

[0008] Preferably, the fixed cover is assembled and connected to the sealing cylinder, the top end of the sealing cylinder is fixedly connected to a connecting ring, the rotating disk is rotatably connected to the sealing cylinder, and the positioning plate is movably connected to the fixed cover. The winch wire is connected to the sealing cylinder through the connecting ring. The sampling device is placed into the water at different depths by the winch winding or releasing the wire.

[0009] Preferably, a connecting gear ring is fixedly connected to the surface of the rotating disk, and an electric motor is fixedly connected inside the sealing cylinder. A power gear is fixedly connected to the output end of the electric motor, and the power gear meshes with the connecting gear ring. When the electric motor is started, it controls the rotation of the power gear, which in turn drives the connecting gear ring to rotate, thereby controlling the rotation of the rotating disk to adjust the position of the sampling tube.

[0010] Preferably, an electric push rod is fixedly connected to the surface of the fixed cover, and a snap-fit ​​buckle is fixedly connected to the output end of the electric push rod. The snap-fit ​​buckle is snapped into the push plate, and the push plate is slidably connected to the sampling tube. The electric push rod drives the snap-fit ​​buckle to move upward, thereby causing the push plate to drive the sliding piston to move.

[0011] Preferably, a fixing plate is fixedly connected inside the sampling tube, and a sealing plug is slidably connected inside the fixing plate. The bottom end of the sealing plug abuts against the water inlet of the sampling tube. The water inlet of the sampling tube is sealed by the sealing plug to prevent the water inside the sampling tube from flowing out after the water is extracted.

[0012] Preferably, a telescopic spring is fixedly connected to the surface of the fixing plate, and the bottom of the telescopic spring is fixedly connected to the sealing plug. An observation window is fixedly connected to the surface of the sealing cylinder.

[0014] This utility model provides a water body testing sampling device, which has the following beneficial effects:

[0015] This water sampling device uses a rubber ring to seal the gap between the fixed cover and the positioning plate, preventing water from entering the sealed cylinder and damaging the internal electrical equipment. A filter screen filters the liquid extracted by the sampling tubes, preventing impurities from affecting water detection. A rotating disc and positioning plate fix and position several sampling tubes. Multiple sampling tubes facilitate sampling from different locations, and the fact that the sampling tubes are fixed inside the sealed cylinder reduces sample storage difficulty and improves the device's convenience in sampling water from different locations.

[0016] This water sampling device connects a winch wire to a sealing cylinder via a connecting ring. By winding or releasing the wire, the sampling device can be placed at different depths in the water, improving the convenience of sampling at different depths. A motor starts the device, controlling a power gear to rotate. This gear, in turn, rotates a connecting gear ring, controlling the rotation of a rotating disc and adjusting the position of the sampling tube. The next blank sampling tube is positioned directly above the filter screen, facilitating sampling from the next water source. An electric push rod moves the locking buckle upwards, causing a push plate to move a sliding piston, creating negative pressure inside the sampling tube to extract water from the surrounding environment. A fixing plate positions the sealing plug.

[0017] This water sampling device seals the inlet of the sampling tube with a sealing plug to prevent water from flowing out after extraction, thus improving the accuracy of water sample collection. A telescopic spring provides thrust to the sealing plug, ensuring it seals the inlet and preventing it from detaching during device movement. An observation window allows for easy observation of the inside of the sealed tube and facilitates repositioning of the sampling tube, enhancing the convenience of water sampling. A filter screen filters the water sample, preventing impurities from entering the tube. A retaining ring secures the filter screen and facilitates replacement and maintenance. A support rod supports the space around the filter screen, preventing grass or debris from obstructing the sampling and causing sampling failure, thus improving the stability of water sample collection.

[0026] This utility model provides a water body detection sampling device.

[0027] Please see Figure 1 The device includes a sealing cylinder 1 and a fixing cover 2. The fixing cover 2 is assembled and connected to the sealing cylinder 1. The fixing cover 2 is snapped into the bottom of the sealing cylinder 1. After installation, the joint can be reinforced with glue. A connecting ring 3 is fixedly connected to the top of the sealing cylinder 1. The winch wire is connected to the sealing cylinder 1 through the connecting ring 3. The sampling device can be placed into the water at different depths by winding or releasing the wire through the winch, which improves the convenience of sampling at different depths of the water.

[0028] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The sealing cylinder 1 is equipped with a sampling mechanism 4, which includes a rotating disk 401, a positioning plate 405, and a sampling tube 406. The rotating disk 401 is rotatably connected to the sealing cylinder 1, and the positioning plate 405 is movably connected to the fixed cover 2. The two ends of the sampling tube 406 are fixedly connected to the rotating disk 401 and the positioning plate 405, respectively. A sliding piston 407 is slidably connected inside the sampling tube 406, and a push plate 408 is fixedly connected to the top of the sliding piston 407. The rotating disk 401 and the positioning plate 405 fix and position several sampling tubes 406. The multiple sampling tubes 406 facilitate the extraction of water from different locations, improving the convenience of the device for sampling water from different locations.

[0029] A connecting gear ring 402 is fixedly connected to the surface of the rotating disk 401. A motor 404 is fixedly connected inside the sealing cylinder 1. A power gear 403 is fixedly connected to the output end of the motor 404, and the power gear 403 meshes with the connecting gear ring 402. The operator can use a switch to start the motor 404. By starting the motor 404, the motor 404 controls the power gear 403 to rotate. The power gear 403 drives the connecting gear ring 402 to rotate, thereby controlling the rotation of the rotating disk 401. The position of the sampling tube 406 is adjusted so that the next blank sampling tube 406 is directly above the filter screen 502, making it convenient for the device to sample the next water body.

[0030] The 404 series electric motor can be used with high-torque brushless DC motors or small motors, such as the R130 series.

[0031] An electric push rod 412 is fixedly connected to the surface of the fixed cover 2. A snap fastener 413 is fixedly connected to the output end of the electric push rod 412, and the snap fastener 413 is snapped into the push plate 408. The push plate 408 is slidably connected to the sampling tube 406. The operator can use a switch to control the electric push rod 412 to start. The electric push rod 412 drives the snap fastener 413 to move upward, which causes the push plate 408 to drive the sliding piston 407 to move, so that a negative pressure is formed inside the sampling tube 406 to extract water from the outside.

[0032] The electric push rod 412 can be a 24V electric telescopic rod with a length of 300mm.

[0033] A fixing plate 409 is fixedly connected inside the sampling tube 406. A sealing plug 410 is slidably connected inside the fixing plate 409. The bottom end of the sealing plug 410 abuts against the water inlet of the sampling tube 406. The fixing plate 409 positions the sealing plug 410 and seals the water inlet of the sampling tube 406 to prevent water from flowing out of the sampling tube 406 after water is extracted, thereby improving the accuracy of water sample extraction by the sampling tube 406.

[0034] A telescopic spring 411 is fixedly connected to the surface of the fixed plate 409, and the bottom of the telescopic spring 411 is fixedly connected to the sealing plug 410. An observation window 414 is fixedly connected to the surface of the sealing cylinder 1. The telescopic spring 411 provides a pushing force to the sealing plug 410, so that the sealing plug 410 seals the water inlet of the sampling tube 406, preventing the sealing plug 410 from falling off the water inlet when the device is moved. The observation window 414 allows for easy observation of the internal condition of the sealing cylinder 1 and facilitates the repositioning of the sampling tube 406, thereby improving the convenience of the device for water sampling.

[0035] Please refer to it again. Figure 1 and Figure 4The bottom of the fixed cover 2 is provided with a filter mechanism 5, which includes a rubber ring 501 and a filter screen 502. The rubber ring 501 is fixedly connected to the fixed cover 2. The rubber ring 501 seals the gap between the fixed cover 2 and the positioning plate 405 to prevent water from entering the sealed cylinder 1 and causing damage to the internal electric equipment. The filter screen 502 filters the liquid extracted by the sampling tube 406 to prevent impurities from affecting the water detection.

[0036] The filter screen 502 is slidably connected to the fixed cover 2, and the filter screen 502 is in close contact with the rubber ring 501. The surface of the fixed cover 2 is rotatably connected to a retaining ring 503 for positioning the filter screen 502, and one end of the retaining ring 503 is engaged with the fixed cover 2. A support rod 504 is fixedly connected to the surface of the retaining ring 503. The filter screen 502 filters the water sample extracted by the sampling tube 406, preventing impurities from entering the interior of the sampling tube 406. The retaining ring 503 fixes the filter screen 502 and facilitates its replacement and maintenance. The support rod 504 supports the space near the filter screen 502, preventing grass or garbage from covering it and causing the sampling tube 406 to fail to extract water samples, thus improving the stability of water sample extraction.

[0037] Working principle: First, the device is submerged into the water body to be sampled. The electric push rod 412 is activated via its control switch. The push rod 412 moves the locking buckle 413 upwards, causing the push plate 408 to move the sliding piston 407, creating negative pressure inside the sampling tube 406. This draws water from the outside environment, which is then filtered through the filter screen 502. After the water sample is extracted, the telescopic spring 411 provides thrust to the sealing plug 410, sealing the inlet of the sampling tube 406. The control switch of the motor 404 is pressed, causing the motor 404 to control the rotation of the power gear 403. The power gear 403 drives the connecting gear ring 402 to rotate, controlling the rotation of the rotating disk 401 and adjusting the position of the sampling tube 406. Simultaneously, the electric push rod 412 is activated, returning it to its initial state. The motor 404 continues to adjust the position of the sampling tube 406. Position the next empty sampling tube 406 directly above the filter screen 502, and simultaneously slide the push plate 408 into the middle of the locking buckle 413 to facilitate sampling of the next water body. When water samples need to be extracted, activate the electric push rod 412 to adjust the locking buckle 413 to the top, rotate the sampling tube 406 through the motor 404, adjust the sampling tube 406 to be tested to the position of the filter screen 502, open the retaining ring 503, and remove the filter screen 502. Insert the suction tube of the detection device into the sampling tube 406 and push the sealing plug 410 upward. Drive the locking buckle 413 downward through the electric push rod 412, so that the sliding piston 407 squeezes the water inside the sampling tube 406 and squeezes the water inside the sampling tube 406 into the detection equipment. With the above device, water samples can be taken and stored at multiple locations, reducing the cumbersomeness of water body sampling and improving the convenience of water body detection.
