[0032] In order for those skilled in the art to better understand the scheme of the present application, the present application is further described in detail below in conjunction with the drawings and specific embodiments.
[0033] The convenient reading water weir measuring needle device of the embodiments of the present application comprises:
[0034] The measuring seat 1 is provided with a measuring hole 122, and the measuring needle assembly 2 penetrates through the measuring hole 122. The measuring needle assembly 2 comprises a measuring needle 21, a scale plate 22 and a measuring block 23. The scale plate 22 is sleeved with the measuring block 23, one end of the measuring needle 21 is detachably connected with the measuring block 23, the other end of the measuring needle 21 penetrates through the measuring hole 122, and the measuring block 23 and the measuring needle 21 move in the extension direction of the scale plate 22,
[0035] The probe 21 includes a probe body 211, a galvanized layer 212, and a non-stick layer 213. The outer peripheral surface of the probe body 211 is provided with the galvanized layer 212, and the outer peripheral surface of the galvanized layer 212 is provided with the non-stick layer 213.
[0036] The convenient water-measuring weir probe device of this application embodiment avoids corrosion from water or impurities during measurement by providing a non-stick layer 213. The probe assembly 2 extends in the vertical direction, that is, the probe 21 extends in the vertical direction.
[0037] Specifically, such as Figures 1 to 6 As shown, the measuring base 1 has a measuring hole 122 that extends vertically. The measuring stylus 21 passes through the measuring hole 122 vertically. A preset gap is provided between the measuring stylus 21 and the measuring hole 122 to adjust the measuring stylus 21 to be parallel to the direction of gravity. This facilitates measurement and ensures the accuracy of manual measurement.
[0038] The probe 21 includes, from the inside out, a probe body 211, a galvanized layer 212, and a non-stick layer 213. The outer peripheral surface of the probe body 211 is coated or plated with a galvanized layer 212 to prevent water corrosion. The non-stick layer 213 is provided on the outer peripheral surface of the galvanized layer 212 to prevent water or impurities from adhering to the surface of the probe 21, which would lead to corrosion and a decrease in the measurement accuracy of the probe 21. It also facilitates the removal of impurities or moisture, reducing maintenance costs.
[0039] The convenient water measuring needle device of this application embodiment, by providing a non-stick layer 213, makes it easier to remove impurities or water, reducing maintenance costs. By providing a galvanized layer 212, corrosion of the needle body 211 by water or impurities is prevented, extending the service life of the needle 21.
[0040] In some embodiments, the scale plate 22 is provided with a guide groove 221 that mates with the probe 21. The guide extends in the vertical direction to limit the probe 21, facilitating better operation of the probe 21 and the measuring block 23 for reading. The limiting effect of the guide groove 221 on the probe 21 can improve the stability and accuracy of the measurement. By restricting the direction of movement of the probe 21, it ensures that the probe 21 moves in the vertical direction, thereby reducing measurement errors caused by excessive tilting or offset of the probe 21. It should be understood that the probe 21 can move left and right or back and forth within the guide groove 221 to adjust the probe 21 to be parallel to the direction of gravity.
[0041] In some implementations, the non-stick layer 213 is made of any one of polytetrafluoroethylene, fluorinated ethylene propylene copolymer, and phenolic resin.
[0042] Specifically, such as Figures 1 to 6As shown, polytetrafluoroethylene is a non-stick material with corrosion resistance, high temperature resistance and non-stickness. It is very stable in chemical and physical properties, which can effectively prevent the adhesion of water and impurities, and make the non-stick layer 213 have certain corrosion resistance.
[0043] Fluorinated ethylene propylene copolymer is a material similar to polytetrafluoroethylene, with chemical corrosion resistance, heat resistance and non-stickness. High transparency, avoid affecting personnel reading.
[0044] Phenolic resin is a thermosetting resin with good heat resistance, chemical corrosion resistance and mechanical strength, which can form a protective layer by coating or dipping. By selecting polytetrafluoroethylene, fluorinated ethylene propylene copolymer or phenolic resin as the material of the non-stick layer 213, the water weir measuring needle device can effectively prevent the adhesion of water and impurities, avoid the adhesion of impurities or the corrosion of water to the measuring needle 21, and improve the measurement accuracy and service life.
[0045] In some embodiments, the size of the non-stick layer in the radial direction of the measuring needle body 211 is 0.5mm-1.0mm, and the size of the galvanized layer 212 in the radial direction of the measuring needle body 211 is greater than the size of the non-stick layer in the radial direction of the measuring needle body 211.
[0046] Specifically, as shown in Figures 1 to 6 The minimum value of the non-stick layer 213 is 0.5mm: this size can ensure that the non-stick layer 213 has enough thickness to prevent water and impurities from adhering to the surface of the measuring needle 21, while also providing certain corrosion protection. The maximum value of the non-stick layer 213 is 1.0mm: this upper limit ensures that the non-stick layer 213 is not too thick, thereby avoiding negative effects on the accuracy and sensitivity of the measuring needle 21. Increasing the thickness of the non-stick layer 213 may increase the diameter of the measuring needle 21, thereby affecting the measurement accuracy. The thickness of the non-stick layer 213 is between 0.5mm and 1.0mm, which can meet the functional requirements and control the cost.
[0047] In some embodiments, the radial size of the measuring needle 21 away from the measuring block 23 gradually decreases. The radial size of the measuring needle 21 gradually decreases at the end away from the measuring block 23, forming a tapered or tapered shape.
[0048] Specifically, as shown in Figures 1 to 6 The tapered design can reduce the resistance of the measuring needle 21 moving in water, making the measuring needle 21 move up and down more smoothly, thereby improving the sensitivity and accuracy of the measurement. Reduce turbulence: the tapered design can reduce the turbulence of water, avoid measurement errors caused by turbulent water flow. Insert and remove: the tapered design makes it easier to insert and remove the measuring needle 21 from the measuring hole 122, making the operation more convenient. The tapered design can reduce the friction between the measuring needle 21 and the inner wall of the measuring hole 122, prolonging the service life of the measuring needle 21.
[0049] In some embodiments, the measuring hole 122 has a first preset interval A with the outer circumferential surface of the measuring needle 21, and 1.0mm≤A≤2.5mm, and the size of the measuring hole 122 in the up-down direction is 2cm-3cm.
[0050] The first preset interval between the measuring hole 122 and the measuring needle 21 has a minimum value of 1.0mm, which can ensure that there is enough space between the measuring needle 21 and the measuring hole 122 for the up-down movement of the measuring needle 21, while reducing friction and wear. The maximum value is 2.5mm: the upper limit of this interval ensures that the space between the measuring needle 21 and the measuring hole 122 is not too large, thereby avoiding excessive deviation or shaking of the measuring needle 21 during measurement. At the same time, it is also convenient for the measuring needle 21 to be parallel to the direction of gravity, and the size of the measuring hole 122 in the up-down direction is 2cm to 3cm. The minimum value is 2cm, which can ensure that the measuring needle 21 has enough space to move up and down, and facilitate the inclination of the measuring needle 21 in the up-down direction to make the extension direction of the measuring needle 21 horizontal to the direction of gravity, while facilitating the operator to read the scale. The maximum value is 3cm, which ensures that the measuring hole 122 is not too large, thereby avoiding excessive deviation or shaking of the measuring needle 21 during measurement, and facilitating the operator to operate.
[0051] The convenient reading water measuring weir measuring needle device of the embodiments of the present application can effectively reduce the friction between the measuring needle 21 and the inner wall of the measuring hole 122, ensure that the measuring needle 21 does not deviate or shake during measurement, and also facilitate the extension direction of the measuring needle 21 to be horizontal to the direction of gravity, thereby improving the accuracy of measurement and the convenience of operation,
[0052] In some embodiments, the convenient reading water measuring weir measuring needle device further comprises a level 3, the measuring seat 1 comprises a vertical plate 11 and a horizontal plate 12, the vertical plate 11 is provided with a plurality of positioning holes, the horizontal plate 12 is provided with a horizontal groove 121 to install the level 3, and the extension direction of the vertical plate 11 is orthogonal to the extension direction of the horizontal plate 12. The vertical plate 11 extends in the up-down direction, the horizontal plate 12 extends in the front-rear direction, the lower end of the vertical plate 11 is connected to the rear end of the horizontal plate 12, the horizontal plate 12 is provided with a measuring hole 122, and the vertical plate 11 is provided with a positioning hole, so that the vertical plate 11 can be arranged on the water measuring weir plate through the positioning hole, and the level 3 facilitates the operator to adjust the horizontal plate 12 to be horizontal, thereby facilitating the scale plate 22 to be orthogonal to the horizontal plate 12 for subsequent measurement.
[0053] The water measuring weir needle device of the embodiment of the present application can effectively ensure that the horizontal plate 12 is kept horizontal, thereby improving the measurement accuracy and the operation convenience.
[0054] In some embodiments, the vertical plate 11 and the horizontal plate 12 are integrally formed to improve the structural strength of the measuring seat 1.
[0055] In some embodiments, the water measuring weir needle device with convenient reading further comprises a gravity ball component 4, which comprises a connecting frame 41, a connecting rope 42 and a gravity ball 43, one end of the connecting frame 41 is connected to the upper end of the vertical plate 11, the lower end of the connecting frame 41 is connected to one end of the connecting rope 42, and the other end of the connecting rope 42 is connected with the gravity ball 43.
[0056] Specifically, as shown in the figure, the upper end of the connecting rope 42 is connected to the connecting frame 41, and the lower end of the connecting rope 42 is connected to the gravity ball 43, thereby facilitating the operator to adjust the measuring needle 21 and the scale plate 22 by referring to the connecting rope 42. Under the action of the gravity of the gravity ball 43, the connecting rope 42 is always kept in a vertical state. The operator can adjust the measuring needle 21 and the scale plate 22 by referring to the vertical direction of the connecting rope 42, to ensure that they are parallel or perpendicular to the direction of gravity, thereby improving the measurement accuracy. Figures 1 to 6
[0057] The water measuring weir needle device of the embodiment of the present application adds the gravity ball component 4 in the water measuring weir needle device, so that the operator can quickly adjust the measuring needle 21 and the scale plate 22 by referring to the vertical state of the connecting rope 42, to ensure that they are correctly aligned with the direction of gravity. This design not only improves the measurement accuracy, but also simplifies the operation process, and forms double insurance with the level 3, thereby improving the stability and convenience of the use of the measuring needle 21 device.

The pointer 44 is connected to the gravity ball 43 and arranged at the end of the gravity ball 43 away from the connecting rope 42. Since the gravity ball 43 is always kept in a vertical state, the pointer 44 will also be kept in a vertical state. The operator can more intuitively adjust the measuring needle 21 and the scale plate 22 by referring to the vertical state of the pointer 44, to ensure that they are parallel to the vertical direction.
