Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water quality testing technology, and in particular relates to a water quality testing sampler. Background Technology
[0002] A water quality sampler is a device used to obtain water samples, typically for testing the physical, chemical, and biological properties of water. Water samplers help scientists, environmental monitors, and engineers understand the degree of pollution, composition, and changes in water bodies.
[0003] Application number CN202323127304.8 discloses a water quality testing sampler, comprising: a support frame, an adjustment component fixedly connected to the outer surface of the support frame, and a sampling component fixedly connected to the lower surface of the adjustment component; the sampling component includes a sampling bucket, an inlet pipe fixedly connected to the outer surface of the sampling bucket near the bottom, and fixing blocks symmetrically fixedly connected to the outer surface of the inlet pipe near the left end. In this invention, the use of insert blocks, fixing blocks, slots, grooves, springs, telescopic rods, and mounting grooves facilitates the installation of a filter frame, thereby filtering out large particles and suspended solids in the water. This reduces subsequent filtration and treatment steps for the sampled liquid, improving sampling efficiency and convenience. Simultaneously, the filter frame can be disassembled for easy cleaning, ensuring the filtration effect.
[0004] When sampling water samples, the complex environment of some water areas makes it difficult to place the device close to the water, resulting in a certain distance between the device placement point and the sampling water area. Furthermore, the length of the device's support frame is fixed, making it difficult to adjust its horizontal length. This makes sampling difficult when the device encounters water areas with complex environments. Utility Model Content
[0005] The purpose of this utility model is to provide a water quality testing sampler. The clockwise operation of the first motor causes the top of the push rod to push the insertion rod to move away from the fixed frame along the mounting rod. The insertion rod drives the retraction mechanism to move, and the retraction mechanism drives the sampling mechanism to move. This allows the horizontal position of the sampling mechanism to be adjusted, solving the problem that the length of the support frame of the device is fixed and it is difficult to adjust its horizontal length, which makes it difficult to sample when the device encounters complex water environments.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0029] Please see Figure 1-5 As shown, this utility model is a water quality testing sampler, including a base 1, a battery 11 fixedly connected to the top of the base 1, a fixing frame 12 fixedly connected to the top of the base 1, a controller 13 fixedly connected to the outer wall of the fixing frame 12, an adjustment mechanism 2 provided on the base 1, a retraction mechanism 3 provided on the adjustment mechanism 2, and a sampling mechanism 4 provided on the retraction mechanism 3.
[0030] The adjusting mechanism 2 includes a first motor 201, which is started clockwise by the controller 13. A threaded rod 202 is fixedly connected to the output end of the first motor 201 via a coupling. Clockwise starting of the first motor 201 causes the threaded rod 202 to rotate. A sliding rod 203 is fixedly connected to the top of the base 1. A slider 204 is threadedly connected to the outer wall of the threaded rod 202. Clockwise rotation of the threaded rod 202 causes the slider 204 to move upwards along the sliding rod 203. A mounting rod 205 is fixedly connected to the outer wall of the fixing frame 12. A limit groove 206 is formed on the mounting rod 205. An insert rod 207 is slidably connected inside the mounting rod 205. A limit piece 208 is fixedly connected to the outer wall of the insert rod 207. A push rod 209 is rotatably connected to the bottom of the insert rod 207. The top of the push rod 209 pushes the insert rod 207 along the mounting rod 205 away from the fixing frame 12. The insertion rod 207 moves in a certain direction, which drives the retraction mechanism 3 to move. The retraction mechanism 3 drives the sampling mechanism 4 to move, thereby adjusting the horizontal position of the sampling mechanism 4 to facilitate sampling in complex water environments and improve the adaptability of the device. The output end of the first motor 201 is rotatably connected to the inside of the fixed frame 12. The end of the threaded rod 202 away from the first motor 201 is rotatably connected to the top of the base 1. The end of the sliding rod 203 away from the base 1 is fixedly connected to the inner wall of the fixed frame 12. The inner wall of the slider 204 is slidably connected to the outer wall of the sliding rod 203. The end of the insertion rod 207 away from the fixed frame 12 passes through the outer wall of the mounting rod 205 and extends. The outer wall of the limiting piece 208 is slidably connected to the inside of the limiting groove 206. The end of the push rod 209 away from the insertion rod 207 is rotatably connected to the outer wall of the slider 204. The slider 204 drives the bottom end of the push rod 209 to move upward.
[0031] The launching and receiving mechanism 3 includes a mounting frame 301, which is fixedly connected to the end of the insertion rod 207 away from the fixed frame 12. A second motor 302 is fixedly connected to the outer wall of the mounting frame 301. The second motor 302 is started in a clockwise manner by the controller 13. The output end of the second motor 302 is rotatably connected inside the mounting frame 301. The output end of the second motor 302 is fixedly connected to a rotating rod 303 through a coupling. The operation of the second motor 302 will drive the rotating rod 303 to rotate. The end of the rotating rod 303 away from the second motor 302 is rotatably connected to the inner wall of the mounting frame 301. A suspension rope 304 is fixedly connected to the outer wall of the rotating rod 303. The rotation of the rotating rod 303 will change the height of the bottom end of the suspension rope 304, thereby changing the position of the sampling mechanism 4 and adjusting the sampling depth.
[0032] Sampling mechanism 4 includes a piston cylinder 401. The top of the piston cylinder 401 is fixedly connected to the end of the suspension rope 304 away from the rotating rod 303. A protective cover 402 is fixedly connected to the inner top wall of the piston cylinder 401. A hydraulic rod 403 is fixedly connected to the inner top wall of the protective cover 402. The hydraulic rod 403 is retracted by the controller 13. The output end of the hydraulic rod 403 is slidably connected inside the protective cover 402. The output end of the hydraulic rod 403 passes through the bottom of the protective cover 402 and extends into the piston cylinder 401. A cross 404 is fixedly connected to the output end of the hydraulic rod 403. The retraction of the hydraulic rod 403 will cause the cross 404 to rise. A piston head 405 is fixedly connected to the end of the cross 404 away from the hydraulic rod 403. The cross 404 causes the piston head 405 to rise, thereby creating a negative pressure inside the piston cylinder 401. The piston head 405 is slidably connected inside the piston cylinder 401. A connecting rod 406 is fixedly connected to the top of the cross 404. During the sampling process, as the cross 404 moves, the connecting rod 406 will also move. The connecting rod 406 moves upward, and an L-shaped plate 407 is fixedly connected to the end of the connecting rod 406 away from the piston head 405. The connecting rod 406 drives the L-shaped plate 407 to move. A cleaning ring 408 is fixedly connected to the end of the L-shaped plate 407 away from the connecting rod 406. The movement of the L-shaped plate 407 drives the cleaning ring 408 to move along the filter screen 409. The filter screen 409 is fixedly connected to the outer wall of the piston cylinder 401. The outer wall of the filter screen 409 contacts the inner wall of the cleaning ring 408, thereby allowing for simple cleaning of the filter screen 409 and preventing water flow from causing it to move. Some debris adheres to the filter screen 409, causing the filter screen 409 to become clogged and affecting the sampling efficiency. The bottom of the piston cylinder 401 is connected to the water inlet pipe 410. Because the water inlet pipe 410 is equipped with a one-way valve, it only allows liquid to enter the inside of the water inlet pipe 410. At this time, the water will enter the inside of the piston cylinder 401 through the water inlet pipe 410. The bottom of the piston cylinder 401 is connected to the water outlet pipe 411. When the valve on the water outlet pipe 411 is closed, the end of the water outlet pipe 411 away from the piston cylinder 401 passes through the bottom of the filter screen 409 and extends.
[0033] One specific application of this embodiment is:
[0034] In use, secure the device, close the valve on the outlet pipe 411, and then start the first motor 201 clockwise via the controller 13. The clockwise start of the first motor 201 will rotate the threaded rod 202, causing the slider 204 to move upwards along the slide rod 203. The slider 204 will then move the bottom of the push rod 209 upwards, and the top of the push rod 209 will push the insertion rod 207 to move away from the fixing frame 12 along the mounting rod 205. The insertion rod 207 will then move the retraction mechanism 3, which in turn moves the sampling mechanism 4, thus adjusting the horizontal position of the sampling mechanism 4 to facilitate sampling in complex water environments and improve the device's adaptability. Then, start the second motor 302 clockwise via the controller 13. The operation of the second motor 302 will rotate the rotating rod 303, causing the bottom of the suspension rope 304 to rise... The position of the sampling mechanism 4 changes, thereby adjusting the sampling depth. Then, the hydraulic rod 403 retracts via the controller 13. The retraction of the hydraulic rod 403 causes the cross 404 to rise, which in turn causes the piston head 405 to rise, creating a negative pressure inside the piston cylinder 401. Because a one-way valve is installed on the water inlet pipe 410, only liquid is allowed to enter the inside of the water inlet pipe 410. At this time, water will enter the inside of the piston cylinder 401 through the water inlet pipe 410. During the sampling process, as the cross 404 moves, the connecting rod 406 also moves upward. The connecting rod 406 drives the L-shaped plate 407 to move, and the movement of the L-shaped plate 407 drives the cleaning ring 408 to move along the filter screen 409, thereby performing simple cleaning of the filter screen 409 and preventing debris from adhering to the filter screen 409 due to water flow, which would cause the filter screen 409 to become clogged and affect the sampling efficiency.
