Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to a sampling device for water quality testing in environmental impact assessment. Background Technology

[0002] Water quality testing is the process of analyzing the physical, chemical, and biological properties of water bodies to assess their quality and determine whether they meet specific standards or usage requirements.

[0003] When using water quality testing devices to test water bodies, the testing end of the device must follow the stratified sampling standard when taking samples.

[0004] If stratified sampling standards are not followed, the test data will not be able to accurately reflect the physical, chemical, and biological differences in the vertical stratification of water bodies, which will ultimately affect the scientific nature and effectiveness of water environment management decisions, and thus mislead the formulation of pollution source tracing, water quality rating, and treatment plans. Utility Model Content

[0005] This invention provides a water quality testing and sampling device for environmental impact assessment, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides a water quality testing and sampling device for environmental impact assessment, comprising: Water quality testing instrument; The outer casing is fixedly installed on one side surface of the water quality analyzer; An anti-slip mat is fixedly installed on the lower surface of the water quality analyzer and its housing; A control panel is embedded in the outer surface of the water quality analyzer. The positioning unit is located in the inner cavity of the outer shell, which enables accurate positioning of the required water intake layer when taking water.

[0007] Furthermore, the positioning unit includes a servo motor and a storage tray. The servo motor is embedded in one side surface of the inner cavity of the housing, and an upper wheel is fixedly mounted on the working end of the servo motor. The storage tray is rotatably mounted on the surface of the inner cavity of the housing. A cable is provided on the outer surface of the storage tray, and a threaded cap is fixedly mounted on one end of the cable through one side surface of the housing. A rack is welded to the outer surface of the upper wheel and engages with a toothed groove on the upper surface of the cable.

[0008] Through the above technical solution, side plates are welded to both sides of the upper wheel, which have a limiting effect on the movement of the cable. Furthermore, springs are installed in the symmetrically opened grooves on the inner surface of the outer shell, and sliders are slidably installed in the symmetrically opened grooves on the inner surface of the outer shell. A lower wheel is rotatably installed on one side surface of the two sliders. A rack is welded to the outer surface of the lower wheel and meshes with a toothed groove opened on the lower surface of the cable. One end of the spring is welded to the symmetrically opened groove on the inner surface of the outer shell, and the other end is welded to the lower surface of the slider. The spring pushes the slider to move the lower wheel upward.

[0009] With the above technical solution, springs are installed in both slots. The two springs are in a flexed state, which can resist the two sliders and make them move upward.

[0010] Furthermore, a spiral spring is installed on the shaft end of the storage tray. One end of the spiral spring is welded to the outer surface of the shaft end of the storage tray, and the other end of the spiral spring is welded to the surface of the inner cavity of the outer shell.

[0011] Through the above technical solution, the spiral spring can automatically store the cable on the storage tray.

[0012] Furthermore, a threaded head is threaded onto the inner surface of the threaded cap, and a sampler is welded to the other end of the threaded head. Two ultrasonic sensors are fixedly mounted on the outer surface of the sampler.

[0013] Using the above technical solution, the ultrasonic sensor can detect the distance between the sampler and the bottom of the water.

[0014] Furthermore, a drain port is fixedly installed on the outer surface of the sampler, and a storage groove is provided on one side surface of the outer shell.

[0015] The above technical solution allows the storage slot to store threaded caps and prevent them from becoming contaminated.

[0016] Furthermore, the lower surface of the inner cavity of the outer shell is provided with a 90° slope, and a counterweight is provided on the lower surface of the inner cavity of the outer shell.

[0017] With the above technical solution, the counterweight is located at the bottom of the sampler, making the sampler perpendicular to the water surface.

[0018] The above-described solution of this utility model has at least the following beneficial effects: This utility model uses an ultrasonic sensor installed on the sampler in the positioning unit to control the start and stop of the upper wheel in conjunction with a servo motor. The upper wheel works in conjunction with the lower wheel to control the adjustment of the cable on the receiving tray, thereby controlling the sampler to reach the specified water layer for water quality sampling and testing, thus achieving accuracy and rigor in water quality sampling and testing. The spring tensions against the slider, which in turn presses upward against the lower wheel, causing the lower wheel to press against the cable and fit tightly against the upper wheel. This ensures the meshing between the lower wheel, the cable, and the upper wheel, thereby controlling the start and stop of the cable and enabling the sampler to accurately reach the set water layer.

[0020] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0021] like Figure 1-4 As shown, an embodiment of this utility model provides a water quality testing and sampling device for environmental impact assessment, comprising: Water quality testing instrument 1; The outer casing 2 is fixedly installed on one side surface of the water quality analyzer 1; Anti-slip mat 3 is fixedly installed on the lower surface of the water quality analyzer 1 and the outer casing 2; The anti-slip pad 3 keeps the water quality tester 1 and the outer casing 2 stable and prevents them from sliding.

[0022] Control panel 4 is embedded in the outer surface of water quality analyzer 1; Positioning unit 5 is installed in the inner cavity of the outer shell 2, so that the required water intake layer can be accurately located when taking water.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning unit 5 includes a servo motor 501 and a storage tray 508. The servo motor 501 is embedded in one side surface of the inner cavity of the housing 2. An upper wheel 502 is fixedly installed at the working end of the servo motor 501. The storage tray 508 is rotatably installed on the surface of the inner cavity of the housing 2. A cable 512 is provided on the outer surface of the storage tray 508. One end of the cable 512 passes through one side surface of the housing 2 and is fixedly installed with a threaded cap 514. A rack 503 is welded to the outer surface of the upper wheel 502 and meshes with the toothed groove 513 opened on the upper surface of the cable 512.

[0024] The tensile strength of cable 512 is 500N.

[0025] Multiple racks 503 are distributed in a ring on the outer surface of the upper wheel 502.

[0026] The servo motor 501 has a self-locking function, which locks the upper wheel 502 and prevents it from working. A rack 503 is welded to the outer surface of the upper wheel 502 and meshes with the toothed groove 513 on the upper surface of the cable belt 512. Side plates are welded to both sides of the upper wheel 502, which limit the movement of the cable belt 512, thereby driving the cable belt 512 to move. The storage tray 508 can roll up and store the cable belt 512. The cable belt 512 contains cables and water pipes.

[0027] The rated torque of servo motor 501 is 2.5 N·m. like Figure 2 , Figure 3 and Figure 4 As shown, springs 504 are installed in the grooves symmetrically opened on the inner surface of the outer shell 2, and sliders 505 are slidably installed in the grooves symmetrically opened on the inner surface of the outer shell 2. A lower wheel 506 is rotatably installed on one side surface of the two sliders 505. A rack 507 is welded to the outer surface of the lower wheel 506 and meshes with the toothed groove 513 opened on the lower surface of the cable 512.

[0028] Multiple racks 507 are distributed in a ring around the lower gear 506.

[0029] Springs 504 are installed in both slots. The two springs 504 are in a flexed state, which can resist the upward movement of the two sliders 505. This causes the lower wheel 506, which is rotated between the two sliders 505, to move upward. This causes the rack 507 of the lower wheel 506 to be in close contact with the toothed groove 513 on the lower surface of the cable 512, so that the upper wheel 502 and the lower wheel 506 clamp the cable 512.

[0030] like Figure 2, Figure 3 and Figure 4 As shown, one end of the spring 504 is welded and installed in a groove symmetrically opened on the inner surface of the housing 2, and the other end is welded and installed on the lower surface of the slider 505. The spring 504 pushes the slider 505 to move the lower wheel 506 upward.

[0031] like Figure 3 As shown, a spiral spring 509 is installed on the shaft end of the storage tray 508. One end of the spiral spring 509 is welded to the outer surface of the shaft end of the storage tray 508, and the other end of the spiral spring 509 is welded to the surface of the inner cavity of the outer shell 2.

[0032] The spiral spring 509 allows the cable 512 to be retracted onto the storage tray 508.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, a threaded head 515 is threaded onto the inner surface of the threaded cap 514, and a sampler 516 is welded onto the other end of the threaded head 515. Two ultrasonic sensors 517 are fixedly mounted on the outer surface of the sampler 516.

[0034] The ultrasonic sensor 517 has a detection accuracy of ±0.05m.

[0035] The threaded head 515 is threadedly connected to the threaded cap 514, thereby indirectly connecting the cable 512 and the sampler 516, so that the internal cables and water pipes of the two are connected, and the ultrasonic sensor 517 can detect the distance of the sampler 516 from the bottom of the water.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, a drain port 518 is fixedly installed on the outer surface of the sampler 516, and a storage groove 519 is provided on one side surface of the outer casing 2.

[0037] When storing the cable 512, water stains will appear on the surface. The water flows into the lower surface of the inner cavity of the outer casing 2 at a 30° slope and flows out through the drain port 518. The storage groove 519 can store the threaded cap 514 to prevent it from being contaminated.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the lower surface of the inner cavity of the outer shell 2 is set with a 30° slope, and a counterweight 520 is provided on the lower surface of the inner cavity of the outer shell 2.

[0039] The counterweight 520 has a mass of 0.8 kg, and the sampler has a total weight of 1.2 kg.

[0040] The counterweight 520 is located at the bottom of the sampler 516, making the sampler 516 perpendicular to the water surface and submerged in the water.

[0041] Working principle: The sampler 516 is installed by threading the threaded head 515 onto the threaded cap 514, thereby indirectly installing the sampler 516 and the cable 512. The control lines and water pipes inside the cable 512 will be connected to the control lines and water pipes in the sampler 516. First, the sampler 516 is placed vertically on the water surface. The sampling depth is set through the housing 2. At this time, the servo motor 501 drives the upper wheel 502 to rotate. While the upper wheel 502 rotates, c511, which is fixedly installed with the upper wheel 502, drives the spiral spring 509 to rotate through b510, thereby driving the collection tray 508 to rotate. The cable 512 wrapped around the outer surface of the collection tray 508 will be released. At the same time, the cable 512 is between the upper wheel 502 and the lower wheel 506, and is connected by rack 503 and rack The second 507 engages with the toothed grooves 513 on the upper and lower surfaces of the cable 512, which guides the cable 512 out. Because the counterweight 520 on the sampler 516 always ensures that the sampler 516 is perpendicular to the water surface, the ultrasonic sensor 517 can detect the bottom of the water. When the set sampling layer is reached, the servo motor 501 will stop working and lock. The cable 512 is locked by the rack 503 on the upper wheel 502 and the toothed grooves 513 on the upper surface of the cable 512, ensuring that the sampler 516 is at the set water surface. With the addition of ultrasonic sensor 517, assuming the water depth is 5m and the sampling depth is 0.5m from the water surface, when the sampler 516 is on the water surface, the ultrasonic sensor 517 detects a depth of 5m at the bottom. When the sampler 516 moves downwards, and the ultrasonic sensor 517 detects a depth of 4.5m from the bottom, it will control the servo motor 501 to stop working. At this time, the sampler 516 is 0.5m above the water surface, reaching the set detection depth. The lower wheel 506 is rotatably mounted between two sliders 505. The sliders 505 are inclined to move upward by a spring 504, which in turn causes the lower wheel 506 to have an upward tendency. The lower wheel 506 cooperates with the upper wheel 502 to tightly clamp the cable 512 between them. This ensures that when the servo motor 501 is locked, the cable 512 is fixed in place by the cooperation of the lower wheel 506 and the upper wheel 502. The spiral spring 509 is added. When the cable 512 extends, the spiral spring 509 will retract. When the cable 512 is retracted, the spiral spring 509 will drive the storage tray 508 to rotate, thereby storing the cable 512.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
