Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to an intelligent water turbidity testing pen. Background Technology

[0002] Whether it is drinking water in daily life or water used in industrial production, agricultural irrigation, aquaculture and other fields, turbidity is one of the key indicators for measuring water quality. The turbidity of water is usually measured using a portable and easy-to-use water turbidity tester.

[0003] The cover assembly used to protect the detection probe on existing water quality testing pens mostly adopts a pull-out switch. After the cover assembly is pulled out and opened, it separates from the water quality testing pen body and needs to be properly stored, otherwise it is easy to lose, resulting in poor performance. Utility Model Content

[0004] In view of this, the present invention provides an intelligent water turbidity testing pen to solve the problem that the cover assembly for protecting the testing probe often adopts a pull-out switch. After the cover assembly is pulled out and opened, it separates from the water quality testing pen body and needs to be properly stored, otherwise it is easy to lose.

[0005] The technical solution proposed by this utility model is: an intelligent water turbidity detection pen, specifically including a detection pen shell, a rectangular mounting plate fixedly connected to the bottom of the detection pen shell, and a turbidity detection probe fixedly connected to the bottom of the rectangular mounting plate.

[0006] A rectangular sliding sleeve is slidably mounted on the outer shell of the testing pen. Two blocking plates are symmetrically rotatably connected to the bottom parts of the two narrow sides of the rectangular sliding sleeve. Two tension springs are symmetrically connected between the same side of the free end of the two blocking plates and the middle part of the back side of the rectangular sliding sleeve. When the testing pen is in an idle state, the rectangular sliding sleeve is slid down and positioned on the bottom part of the testing pen shell, covering the turbidity detection probe inside it. At this time, the two blocking plates are tightened by the two tension springs and cover the bottom opening of the rectangular sliding sleeve. When the testing pen is used for testing, the rectangular sliding sleeve slides upward to expose the turbidity detection probe. During the upward sliding of the rectangular sliding sleeve, the two blocking plates abut against the bottom end of the turbidity detection probe.

[0007] Furthermore, two T-shaped grooves are symmetrically provided on the two narrow sides of the outer shell of the detection pen, and a vertical guide shaft is fixedly installed inside each of the two T-shaped grooves;

[0008] The top of the rectangular sliding sleeve is symmetrically fixed with an L-shaped connecting rod. The two L-shaped connecting rods are symmetrically integrally formed with two T-shaped sliders at their ends. The two T-shaped sliders are in sliding cooperation with the two T-shaped sliding grooves and the two vertical guide shafts in the form of spring push.

[0009] Furthermore, an L-shaped hook plate is fixedly connected to the upper middle position on the back side of the outer shell of the detection pen, and a positioning wedge is integrally formed on the inner side of the bottom part of the L-shaped hook plate.

[0010] A triangular stop is fixedly connected to the middle part of the top of the back side of the rectangular slide. When the triangular stop slides upward with the rectangular slide, its inclined surface abuts against the inclined surface of the positioning wedge.

[0011] Furthermore, a cover plate is fixedly connected to the top of the outer shell of the detection pen, and the two ends of the cover plate abut against and cover the top openings of the two T-shaped sliding grooves.

[0012] The top opening of the rectangular sliding sleeve has two baffles integrally formed symmetrically. The bottom openings of the two T-shaped sliding grooves abut against the rectangular mounting plate. The two ends of the rectangular mounting plate protrude from the outer shell of the detection pen, and the rectangular sliding sleeve abuts against these two ends when it slides downward.

[0013] Furthermore, the bottom ends of the two vertical guide shafts are fixedly connected to the two ends of the rectangular mounting plate, and their top ends are respectively inserted into the two ends of the cover plate.

[0014] Furthermore, the spring that pushes the T-shaped slider is mounted on the vertical guide shaft and compressed between the cover plate and the T-shaped slider.

[0015] Furthermore, an LED display screen is embedded in the middle of the front side of the test pen housing, and a central control module is set inside the test pen housing. Both the LED display screen and the turbidity detection probe are communicatively connected to the LED display screen.

[0016] Furthermore, a glass window is embedded in the front side of the rectangular sliding sleeve. When the rectangular sliding sleeve is positioned in the upper sliding position, the glass window overlaps with the LED display screen.

[0017] The intelligent water turbidity detection pen provided by this utility model has the following beneficial effects:

[0018] 1. A rectangular sliding sleeve and two blocking plates together form a cover component for shielding and protecting the turbidity detection probe from impact. This cover component is integrated into the outer shell of the test pen and adopts a sliding switch design. It can remain on the outer shell of the test pen whether it is in the open or closed state. Compared with the existing technology that sets the cover component as a direct plug-and-play switch, this can avoid the trouble of properly storing the cover component that is separated from the test pen when it is pulled out and opened, so as to avoid the loss of the problem. It is more practical.

[0019] Second, by using the power transmission of the turbidity detection probe in conjunction with the rebound and pulling effect of the two tension springs, the two blocking plates can automatically swing up and down to open and close by relying on the pushing and pulling forces acting directly or indirectly on them when the rectangular sliding sleeve slides up and down. This eliminates the trouble of manually swinging the two blocking plates to open and close each time the cover component is opened and closed, which helps to simplify the opening and closing operation steps of the cover component and improve its usage efficiency.

[0036] Please refer to Figures 1 to 7 Example 1:

[0037] This embodiment proposes an intelligent water turbidity detection pen, including a detection pen shell 1, a rectangular mounting plate 104 fixedly connected to the bottom of the detection pen shell 1, and a turbidity detection probe 4 fixedly connected to the bottom of the rectangular mounting plate 104.

[0038] A rectangular sliding sleeve 3 is slidably mounted on the outer shell 1 of the test pen. Two blocking plates 304 are symmetrically rotatably connected to the bottom part of the two narrow sides of the rectangular sliding sleeve 3. Two tension springs 306 are symmetrically connected between the same side of the free end of the two blocking plates 304 and the middle part of the back side of the rectangular sliding sleeve 3.

[0039] Preferably, the outer shell 1 of the detection pen has two T-shaped grooves 102 symmetrically opened on its two narrow sides, and a vertical guide shaft 105 is fixedly installed inside each of the two T-shaped grooves 102;

[0040] The top of the rectangular sliding sleeve 3 is symmetrically fixed with an L-shaped connecting rod 301. The two L-shaped connecting rods 301 are symmetrically integrally formed with two T-shaped sliders 302 at their ends. The two T-shaped sliders 302 are in sliding cooperation with the two T-shaped sliding grooves 102 and the two vertical guide shafts 105 in the form of spring push.

[0041] Preferably, an L-shaped hook plate 103 is fixedly connected to the upper middle position on the back side of the detection pen shell 1, and a positioning wedge 1031 is integrally formed on the inner side of the bottom part of the L-shaped hook plate 103.

[0044] The top opening of the rectangular sliding sleeve 3 has two baffles 307 integrally formed symmetrically. The bottom openings of the two T-shaped sliding grooves 102 abut against the rectangular mounting plate 104. The two ends of the rectangular mounting plate 104 protrude from the outer shell of the detection pen 1, and the rectangular sliding sleeve 3 abuts against these two ends when it slides downward.

[0045] Preferably, the bottom ends of the two vertical guide shafts 105 are fixedly connected to the two ends of the rectangular mounting plate 104, and their top ends are respectively inserted into the two ends of the cover plate 101.

[0046] Preferably, the spring that pushes the T-shaped slider 302 is mounted on the vertical guide shaft 105 and the compression clamp is placed between the cover plate 101 and the T-shaped slider 302.

[0047] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0048] An LED display screen 2 is embedded in the middle height position of the front side of the test pen shell 1. A central control module is set inside the test pen shell 1. The LED display screen 2 and the turbidity detection probe 4 are both connected to the LED display screen 2. A glass window 303 is embedded in the front side of the rectangular sliding sleeve 3. When the rectangular sliding sleeve 3 is positioned in the upper sliding position, the glass window 303 overlaps with the LED display screen 2.

[0049] The following section provides a detailed explanation of the specific details, implementation steps, functions and interrelationships of the above features, and their roles in achieving this technical solution:

[0050] When the testing pen is idle, the rectangular sliding sleeve 3 slides down and is positioned on the bottom part of the testing pen housing 1, covering the turbidity detection probe 4 inside. At this time, the two blocking plates 304 are tightened by two tension springs 306 and block the bottom opening of the rectangular sliding sleeve 3 (see reference). Figure 1 , Figure 2 and Figure 3 In this state, the rectangular sliding sleeve 3 is in a closed state, which can provide anti-collision protection for the turbidity detection probe 4.

[0051] When using the testing pen, the rectangular sliding sleeve 3 needs to be slid upwards to expose the turbidity detection probe 4, and then the exposed turbidity detection probe 4 is inserted into the water to detect the turbidity of the water. When the rectangular sliding sleeve 3 slides upwards to expose the turbidity detection probe 4, it first drives the two blocking plates 304 to slide upwards and control the two blocking plates 304 to abut against the bottom end of the turbidity detection probe 4. When the two blocking plates 304 abut against the bottom end of the turbidity detection probe 4, they can be pushed backwards by the turbidity detection probe 4 to swing downwards and automatically open the bottom opening of the rectangular sliding sleeve 3. After that, as the rectangular sliding sleeve 3 continues to slide upwards... The rectangular sliding sleeve 3 separates from the turbidity detection probe 4, exposing the turbidity detection probe 4 and completing the exposure operation. As the rectangular sliding sleeve 3 slides upward, it compresses the springs on the two vertical guide shafts 105 via two T-shaped sliders 302. After the two blocking plates 304 are pushed downward and opened, they stretch the two tension springs 306. As the two blocking plates 304 continue to slide upward with the rectangular sliding sleeve 3 after opening, they are pulled by the two tension springs 306 and successively come into contact with the main body of the turbidity detection probe 4 and the two ends of the rectangular mounting plate 104, and are thus contacted by the main body of the turbidity detection probe 4 and the rectangular mounting plate. The two ends of 104 are held in the open position by abutting against each other; when the rectangular sliding sleeve 3 separates from the turbidity detection probe 4, the triangular stop 305 slides upward with the rectangular sliding sleeve 3 and contacts the positioning wedge 1031. When the two contacts, their inclined surfaces are in actual contact. Through the guiding principle of their inclined surfaces, the rectangular sliding sleeve 3 can push and drive the positioning wedge 1031 to move away from the detection pen housing 1 as it slides upward. The positioning wedge 1031 pushes and drives the L-shaped hook plate 103 to bend and deform away from the detection pen housing 1. When the positioning wedge 1031 is driven to move, it opens up space for the triangular stop. Block 305 slides upwards unimpeded through its space. When the triangular stop block 305 slides upwards past the positioning wedge block 1031, the inclined surfaces of the two separate. At this time, the L-shaped hook plate 103, which is bent and deformed by the push, loses the pushing and holding force from the triangular stop block 305, which can drive the positioning wedge block 1031 to automatically spring back and reset. After the positioning wedge block 1031 resets, the rectangular slide sleeve 3 and the triangular stop block 305 slide downwards under the counter-push of the compressed spring, and the bottom end of the triangular stop block 305 abuts against the top end of the positioning wedge block 1031. At this time, the positioning wedge block 1031 can block and position the rectangular slide sleeve 3 in the upward opening state.

[0052] When the testing operation is completed and the testing pen is idle, the rectangular sliding sleeve 3 should be slid down to reset and close, and then placed over the turbidity testing probe 4 to provide shielding and anti-collision protection for the turbidity testing probe 4. When slid down to reset the rectangular sliding sleeve 3, first pull the vertical part of the testing pen housing 1 towards one side, so that the top of the positioning wedge 1031 separates from the bottom of the triangular stop 305. After the two separate, the rectangular sliding sleeve 3 is exposed. At this time, the springs on the two vertical guide shafts 105 lose the upward sliding and pushing force from the rectangular sliding sleeve 3, and will rebound and push against the two T-shaped... The slider 302 and the rectangular sliding sleeve 3 slide downwards and cover the turbidity detection probe 4, completing the downward reset operation of the rectangular sliding sleeve 3. During the above process, the two blocking plates 304 in the open position will slide down synchronously with the rectangular sliding sleeve 3. When the rectangular sliding sleeve 3 slides down to the lowest position and covers the turbidity detection probe 4, the two blocking plates 304 in the open position will disengage from the turbidity detection probe 4 and lose the retaining force of the turbidity detection probe 4. They can automatically rotate back and close under the rebound pull of the two stretched tension springs 306 and cover the bottom opening of the rectangular sliding sleeve 3.

[0053] The rectangular sliding sleeve 3 and the two blocking plates 304 together form a cover component for shielding and preventing impact to the turbidity detection probe 4. The cover component is integrated and installed on the outer shell 1 of the detection pen and adopts a sliding switch design. It can remain on the outer shell 1 of the detection pen whether it is in the open or closed state. Compared with the existing technology that sets the cover component as a direct plug-and-play switch, it can avoid the trouble of properly storing the cover component that is separated from the detection pen when it is pulled out and opened, so as to avoid the loss of the problem. It is more practical.

[0054] By using the power transmission of the turbidity detection probe 4 in conjunction with the rebound and pulling effect of the two tension springs 306, the two blocking plates 304 can automatically swing up and down to open and close by relying on the pushing and pulling forces directly or indirectly acting on them when the rectangular sliding sleeve 3 slides up and down. This eliminates the trouble of manually swinging the two blocking plates 304 to open and close each time the cover component is opened and closed, which helps to simplify the opening and closing operation steps of the cover component and improve its usage efficiency.

[0055] The working principle of this embodiment is as follows: During the detection process, when the turbidity detection probe 4 is inserted into the water, the turbidity detection probe 4 uses the turbidity detection sensor installed on it to detect the turbidity of the water. The turbidity detection probe 4 can generate different detection signals according to different turbidities of the water. After obtaining these detection signals, the turbidity detection probe 4 transmits them to the central control module. After receiving these detection signals, the central control module uses its built-in intelligent analysis program to process these detection signals and quantify them into corresponding turbidity data. After the turbidity data is quantified, the central control module transmits it to the LED display screen 2 and displays it in real time for the staff to view. By viewing the turbidity data displayed on the LED display screen 2, the staff can finally obtain the detection value of the water turbidity.

[0056] It is worth noting that the selection of specifications and models of the turbidity detection probe 4, the central control module, and the LED display screen 2, as well as the connection and wiring methods and control principles between them, are existing technologies for those engaged in the intelligent design, testing, modification, and maintenance of products in this field, and therefore will not be elaborated here.
