Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultrasonic wind direction and speed sensor assembly, in particular to a jig for assembling an ultrasonic wind direction and speed sensor and a method of using the same. BACKGROUND

[0002] Compared with traditional wind speed sensors, ultrasonic wind speed and direction sensors have the advantages of good measurement accuracy and multiple functions. Ultrasonic wind speed and direction sensors are measurement sensors or measurement instruments that use transmitted sound wave pulses to measure the time or frequency (Doppler shift) difference at the receiving end to calculate wind speed and direction. The main function is to use the ultrasonic time difference method to measure wind speed. The speed of sound in air is superimposed with the air flow speed in the wind direction. If the propagation direction of the ultrasonic wave is the same as the wind direction, its speed will increase; otherwise, its speed will decrease. Therefore, under fixed detection conditions, the speed of ultrasonic wave propagation in air can be functionally related to wind speed. By calculation, the accurate wind speed and direction can be obtained. Compared with conventional wind cups or rotor-type anemometers, the biggest feature of ultrasonic wind speed and direction sensors is that the entire wind measurement system has no mechanical rotating parts and belongs to inertia-free measurement, so it can accurately measure the high-frequency components of gusts in natural wind. Combined with modern computer technology, it can reveal the characteristics of natural wind at a higher level, which has great significance for improving wind resistance and disaster reduction capacity and rational utilization of wind resources.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] It should be noted that, as shown in Figure 2 The ultrasonic wind direction and speed sensor 200 of the embodiment of the present application generally includes a probe seat 201 and a plurality of probe rods 202, and the number of probe rods 202 is generally four, wherein the probe seat 201 is provided with a plurality of hole bodies 203, and the number of hole bodies 203 is consistent with the number of probe rods 202. The assembly process of the present application is to accurately insert and fix the end of each probe rod 202 into the hole body 203 to be fixedly connected with the probe seat 201, and the spacing between each probe rod 202 meets the design requirements, that is, the assembly process is completed. Of course, in other embodiments, the assembly process of the ultrasonic wind direction and speed sensor 200 can also include other assembly steps, which are not particularly limited here.

[0036] The embodiment of the present application provides a jig 100 (hereinafter referred to as jig 100) for assembling an ultrasonic wind direction and speed sensor 200, as shown in Figures 1 to 5 The jig 100 includes a base 1, a positioning cylinder 2 and a plurality of fixing mechanisms 3.

[0037] The positioning cylinder 2 is vertically arranged on the base 1, and the top of the positioning cylinder 2 is provided with a fixing position for fixing the probe seat 201. When the ultrasonic wind direction and speed sensor 200 needs to be assembled, the base 1 is first fixed to an external mechanism, such as an operating table or the ground, etc. through a fastening device, so as to avoid the whole jig 100 from being deviated during the installation process, thereby affecting the assembly efficiency and effect; after the base 1 is fixed, the hole body 203 of the probe seat 201 is adjusted to one-to-one correspondence according to the position of each fixing mechanism 3, and then the probe seat 201 is fixed to the fixing position of the positioning cylinder 2. Specifically, the probe seat 201 can be inserted and fixed at the top of the positioning cylinder 2 or locked at the positioning cylinder 2 through a locking structure, so that the probe seat 201 is located at a predetermined height, which is suitable for the shape of the probe rod 202, and facilitates the subsequent connection with the probe rod 202 and the spacing adjustment of the probe rod 202.

[0038] The fixing mechanism 3 includes a fixed part 31 and a movable part 32. Each fixed part 31 is arranged on the base 1 and is dispersedly arranged along the circumferential direction of the bottom of the positioning cylinder 2. The movable part 32 is movably connected with the base 1 and can be moved to a first position or a second position relative to the base 1, so as to cooperate with the fixed part 31 to form a state of fixing the probe rod 202 or a state of loosening the probe rod 202. It should be noted that the number of the fixing mechanism 3 is consistent with the number of the probe rod 202, and the fixing mechanism 3 is used to fix the end of the probe rod 202 away from the probe seat 201. After the first end of the probe rod 202 coated with structural adhesive is inserted and fixed to the hole body 203 of the probe seat 201 on the positioning cylinder 2 which is also coated with structural adhesive, the position of the second end of the probe rod 202 is adjusted to the position between the fixed part 31 and the movable part 32, so that the spacing between the second ends of the probe rods 202 meets the design accuracy requirement. Then, the movable part 32 is moved to the first position relative to the base 1 to cooperate with the fixed part 31 to form a state of fixing the second end of the probe rod 202. When it is needed to loosen the second end of the probe rod 202, the movable part 32 is moved to the second position relative to the base 1 to cooperate with the fixed part 31 to form a state of loosening the second end of the probe rod 202.

[0039] It should be noted that the structural adhesive refers to a fixing adhesive used to fix the probe seat 201 and the probe rod 202, and can fill the gap between the probe rod 202 and the hole body 203 of the probe seat 201 after they are inserted and cooperated, so as to prevent the probe rod 202 and the probe seat 201 from being deviated.

[0040] Specifically, the method for using the jig 100 includes the following steps:

[0041] The hole body 203 of the probe seat 201 is coated with structural adhesive, and the probe seat 201 is placed in the fixing position of the positioning cylinder 2 for fixation;

[0042] The first end of the probe rod 202 is coated with structural adhesive, the first end of the probe rod 202 is inserted into the hole body 203 of the probe seat 201, and the second end of the probe rod 202 is fixed by adjusting the position of the movable part 32 relative to the base 1 to cooperate with the fixed part 32;

[0043] After the structural adhesive is initially cured, the fastening screws are screwed into the threaded holes of the probe seat 201 and the probe rod 202 in sequence, the probe rod 202 and the probe seat 201 are further fixed to obtain an ultrasonic wind direction and speed sensor 200 assembly, and after waiting for the structural adhesive to completely cure, the product is inspected and qualified and then stored in a semi-finished product warehouse.

[0044] In summary, the jig 100 cooperates with the base 1, the positioning cylinder 2 and the plurality of fixing mechanisms 3, wherein the probe seat 201 of the ultrasonic wind direction and speed sensor 200 is fixed by the fixing position at the top of the positioning cylinder 2, the movable part 32 of the fixing mechanism 3 is movable relative to the base 1 to cooperate with the fixed part 31 to form a state of fixing the probe rod 202 or loosening the probe rod 202, the probe seat 201 and the probe rod 202 of the ultrasonic wind direction and speed sensor 200 can be quickly assembled, and the connection state of the probe seat 201 and the probe rod 202 and the spacing between the probe rods 202 can be well controlled, thereby reducing the problem of assembly error.

[0045] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 5 , the top of the positioning cylinder 2 has a placement groove 21 for fixing the probe seat 201, the placement groove 21 is a fixing position, and the peripheral wall of the positioning cylinder 2 is provided with a plurality of plug-in holes 22 in communication with the placement groove 21 along the peripheral direction of the positioning cylinder 2. Specifically, in this embodiment, the positioning cylinder 2 has a hollow pipe structure, and the radial length of the placement groove 21 at the top of the positioning cylinder 2 is greater than the radial length of the hollow pipe to form a stepped surface. The probe seat 201 is accommodated in the placement groove 21 of the positioning cylinder 2 and is arranged on the stepped surface, so that the probe seat 201 is fixed to the top of the positioning cylinder 2. The hole body 203 of the probe seat 201 is arranged in one-to-one correspondence with the plug-in holes 22, and the first end of the probe rod 202 is inserted into the plug-in hole 22 to be accurately inserted into the hole body 203 of the probe seat 201.

[0046] In some embodiments, as shown in Figure 1 and Figure 3As shown, the jig 100 further comprises a pressing mechanism 4 movably arranged at the top of the positioning cylinder 2 and capable of moving relative to the positioning cylinder 2 to a state of pressing the probe seat 201 or a state of loosening the probe seat 201. When the probe seat 201 is placed at the placement groove 21 of the positioning cylinder 2, the pressing mechanism 4 is adjusted to move relative to the positioning cylinder 2 to the state of pressing the probe seat 201, so that the probe seat 201 is firmly fixed in the placement groove 21, and the probe seat 201 is prevented from being deviated relative to the placement groove 21. After assembly, the pressing mechanism 4 is adjusted to move reversely relative to the positioning cylinder 2 to loosen the probe seat 201, which is simple and convenient to operate and has good fixing effect. Specifically, the pressing mechanism 4 can at least partially abut against the probe seat 201 through rotary motion or overturning motion to form a structure for pressing the probe seat 201, which is not particularly limited here.

[0047] In some embodiments, as shown in Figure 1 The pressing mechanism 4 comprises a rotating shaft 41, a pressing plate 42 and a fastener 43. The rotating shaft 41 is vertically arranged at the top of the positioning cylinder 2. The first end of the pressing plate 42 is rotationally connected with the rotating shaft 41, and the second end is provided with a first connecting hole. The side of the top of the positioning cylinder 2 opposite to the rotating shaft 41 is provided with a second connecting hole. When the pressing plate 42 is rotated relative to the rotating shaft 41 to make the first connecting hole correspond to the second connecting hole, the pressing plate 42 is fixed to the top of the positioning cylinder 2 by being sequentially inserted into the first connecting hole and the second connecting hole through the fastener 43. At this time, the pressing plate 42 spans the slot of the placement groove 21, and the pressing plate 42 can press the probe seat 201 placed in the placement groove 21. That is, it can be understood that by rotating the pressing plate 42 relative to the positioning cylinder 2, the pressing plate 42 is rotated to correspond to the first connecting hole and the second connecting hole, and then locked by the fastener 43 to form a state of spanning the slot of the placement groove 21 to press the probe seat 201, or the pressing plate 42 is rotated to be misaligned relative to the slot of the placement groove 21 to loosen the probe seat 201, which has the characteristics of simple structure, convenient operation and firm fixation.

[0048] In some embodiments, as shown in Figure 3 The positioning cylinder 2 is recessed downward along the top thereof to form an insertion hole 22. The structure of the insertion hole 22 can form a guiding and positioning effect, so that the probe rod 202 can be quickly and accurately inserted into the hole body 203 of the probe seat 201 from the opening of the insertion hole 22 during insertion. Of course, in other embodiments, a closed insertion hole 22 can also be directly formed in the peripheral wall of the positioning cylinder 2 at a position corresponding to the hole body 203, so that the first end of the probe rod 202 can be smoothly inserted into the hole body 203.

[0049] In some embodiments, as shown in Figure 1 and Figure 3As shown, the end of the fixing member 31 opposite to the positioning cylinder 2 is provided with a clamping groove 311 for clamping the end of the probe rod 202, the movable member 32 includes a guide seat 321 and a quick clamp 322, the guide seat 321 is arranged on the base 1 and located on the side of the fixing member 31 away from the positioning cylinder 2, the guide seat 321 is provided with a guide hole 323, the output end of the quick clamp 322 is movably arranged in the guide hole 323, and the output end of the quick clamp 322 is connected with a clamping member 33, and the clamping member 33 reciprocates between the clamping groove 311 and the guide seat 321. It should be noted that the shape of the probe rod 202 is a bent body structure with multiple bends, and the first end and the second end of the probe rod 202 are in the same direction, so the end of the fixing member 31 opposite to the positioning cylinder 2 is provided with a clamping groove 311, which can preliminarily clamp the end of the second end of the probe rod 202, the quick clamp 322 and the guide seat 321 are arranged on the base 1 on the side of the fixing member 31 away from the positioning cylinder 2, so that the movement of the quick clamp 322 driving the clamping member 33 can make the clamping member 33 abut against the probe rod 202, and the probe rod 202 is clamped between the clamping member 33 and the clamping groove 311, preventing the probe rod 202 from being offset due to other human or environmental factors, and ensuring that the spacing of the probe rods 202 meets the preset requirements. In addition, the guide hole 323 of the guide seat 321 can guide the movement of the output end of the quick clamp 322, so that the output end of the quick clamp 322 can reciprocate along the preset trajectory, effectively preventing the output end of the quick clamp 322 from being offset during reciprocating movement and affecting the clamping effect of the probe rod 202. Specifically, the quick clamp 322 is preferably a push-pull type quick clamp, which is a commonly used clamp structure.

[0050] Specifically, as shown in the drawings, Figure 5 the guide seat 321 can be provided with a first threaded hole, and the base 1 is also provided with a second threaded hole corresponding to the position of the first threaded hole, and the guide seat 321 can be fixed to the base 1 by thread members arranged in the first threaded hole and the second threaded hole in sequence, which is stable and convenient to disassemble and assemble.

[0051] In some embodiments, as shown in the drawings, Figure 4 and Figure 5As shown, the height of the guide hole 323 is higher than that of the clamping groove 311, and the center line of the guide hole 323 is in the same axis with the center line of the clamping groove 311 in space. It can be understood that, by making the center line of the guide hole 323 in the same axis with the center line of the clamping groove 311 in space, the quick clamp 322 and the fixing member 31 can form a structure pair clamping the probe rod 202 in opposite directions, improving the clamping effect, and by setting the height of the guide hole 323 higher than that of the clamping groove 311, the clamping member 33 connected to the output end of the quick clamp 322 can abut against the position of the probe rod 202 higher than the position of the second end of the probe rod 202 clamped by the clamping groove 311, so as to adapt to the shape of the probe rod 202 and stably clamp the probe rod 202.

[0052] In some embodiments, as shown in Figure 1 and Figure 3 As shown, the clamping member 33 is in a V-shaped structure or a U-shaped structure, and the opening of the clamping member 33 faces the fixing member 31, so that the clamping member 33 can adapt to the shape of the probe rod 202 and avoid positional deviation between the clamping member 33 and the probe rod 202 when the clamping member 33 abuts against the probe rod 202. Of course, in other embodiments, the structure of the clamping member 33 can also be other suitable shapes, which are not particularly limited herein.

[0053] In some embodiments, as shown in Figure 3 As shown, the fixing mechanism 3 is provided with four fixing mechanisms 3, which are arranged around the positioning cylinder 2 to ensure that the probe rods 202 are evenly arranged, so that the distance between the two probe rods 202 distributed at 180° meets the design requirements. In addition, the number of the insertion holes 22 is also four, and each insertion hole 22 is arranged in one-to-one correspondence with each fixing mechanism 3 in the axial direction of the positioning cylinder 2, so as to guide and position each probe rod 202.

[0054] In some embodiments, a plurality of handles can also be arranged on the base 1 near the edge, which facilitates the user to lift the jig 100 or carry the jig 100. The base 1 can be a rubber structure.

[0055] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
