Description
Technical Field
[0001] The utility model relates to a pitot tube installation tool for a wind speed transmitter, which is mainly used in the technical field of installation of the pitot tube of the wind speed transmitter. Background Art
[0002] like Figure 1 As shown, in the prior art, when installing the Pitot tube 101 of the integrated wind speed transmitter product, the Pitot tube 101 is first screwed onto the housing 102 of the wind speed transmitter. After being screwed to the root, the worker visually checks whether the air inlet direction of the Pitot tube 101 is parallel to the table 103 (that is, whether the air inlet direction of the Pitot tube is parallel to the end face of the wind speed transmitter). If not, the Pitot tube 101 is rotated in the opposite direction to a visually parallel position, and finally the locking nut 104 is tightened to complete the assembly of the product.
[0003] The disadvantage is that the worker's visual inspection can only achieve visual parallelism of the air inlet direction of the pitot tube 101, resulting in large errors and difficulty in ensuring the consistency of each product. Since the parallelism of the pitot tube of the wind speed transmitter product has a great influence on the product accuracy, it is difficult to ensure the product quality and consistency. Summary of the invention
[0004] The utility model aims to solve the above-mentioned problems and provide a pitot tube installation tool for a wind speed transmitter to improve the parallelism and consistency of the pitot tube installation.
[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:
[0006] A pitot tube installation tool for a wind speed transmitter, comprising:
[0007] mesa;
[0008] The tooling body is installed on the table top; it has a first wall, a second wall arranged opposite to the first wall, and a locking screw threadedly connected to the first wall; the locking screw can move between a first position and a second position relative to the second wall, forcing the Pitot tube located between the first wall and the second wall to rotate along its axis relative to the wind speed transmitter. When in the second position, the plane where the axis of the first tube and the axis of the second tube of the Pitot tube are located is parallel or substantially parallel to the plane where the table top is located.
[0009] Preferably, when the locking screw is in the second position, the end faces of the full-pressure end of the first tube and the static-pressure end of the second tube are in contact with the end of the locking screw and the second wall respectively.
[0010] Preferably, the plane where the second wall is located and the plane where the end face of the locking screw is located are both perpendicular or substantially perpendicular to the plane where the table top is located; when the locking screw is in the second position, the plane where the end face of the full-pressure end of the first tube is located and the plane where the end face of the static-pressure end of the second tube is located are both perpendicular or substantially perpendicular to the plane where the table top is located.
[0011] Preferably, when the locking screw is in the first position, the distance from the end face of the full-pressure end of the first tube to the end face of the static-pressure end of the second tube is smaller than the distance from the end of the locking screw to the second wall.
[0012] Preferably, when the locking screw is in the first position, the plane where the end face of the full-pressure end of the first tube and the plane where the end face of the static-pressure end of the second tube are located are parallel or substantially parallel, and are arranged at an acute angle to the plane where the table top is located.
[0013] Preferably, the plane where the end face of the full-pressure end of the first tube and the plane where the end face of the static-pressure end of the second tube are located are perpendicular or substantially perpendicular to the plane where the axis of the first tube and the axis of the second tube of the Pitot tube are located.
[0014] Preferably, the tooling body comprises:
[0015] A connecting portion, mounted on the table top;
[0016] The adjusting part is located on the connecting part and is provided with a groove for the full pressure end of the first tube and the static pressure end of the second tube to extend into, thereby forming the first wall and the second wall on both sides of the groove.
[0017] Preferably, the connecting portion and the adjusting portion are integrally formed and are L-shaped as a whole.
[0018] Preferably, the installation tool also includes a clamp to clamp the connecting part on the table top.
[0019] Preferably, the clamp is a C-type clamp.
[0020] The beneficial effects of the utility model are:
[0021] 1. By utilizing the movement of the locking screw relative to the second wall, the locking screw and the second wall cooperate to force the Pitot tube to rotate along its axis relative to the wind speed transmitter, so that the plane where the axis of the first tube and the axis of the second tube of the Pitot tube are located is parallel or substantially parallel to the plane where the table is located. In this way, compared with the visual method used in the prior art, not only can the parallelism of the Pitot tube installation be improved, but also after the Pitot tube is installed using the tooling, the consistency of the product is relatively high.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0033] The working principle of the pitot tube is to determine the airflow velocity by measuring the total pressure and static pressure of the airflow. When the pitot tube measures the velocity, its total pressure end is aligned with the incoming flow, and the static pressure end is facing away from the incoming flow; in order to ensure the measurement accuracy, it is necessary to ensure that the end face of the total pressure end is facing the incoming flow direction as much as possible. However, during the measurement process, the total pressure end and the static pressure end of the pitot tube are both extended into the pipe of the airflow to be measured, and the staff cannot determine whether the end face of the total pressure end is facing the incoming flow direction. Therefore, when installing the pitot tube on the wind speed transmitter product, it is necessary to ensure the parallelism of the pitot tube and the wind speed transmitter (for example, the parallelism of the plane where the axes of the two tubes on the pitot tube are located and the end face of the wind speed transmitter). During the installation process, the installation angle of the wind speed transmitter is used to determine whether the end face of the total pressure end of the pitot tube is facing the incoming flow direction.
[0034] like Figure 2 As shown, a pitot tube installation tool for a wind speed transmitter includes a table top 1 and a tool body 2 installed on the table top 1.
[0035] The table top 1 may be any component with a flat surface, such as a workbench, a table, etc. In practical applications, it is used to place the wind speed transmitter so that at least one end surface of the wind speed transmitter is in contact with the upper surface of the table top 1.
[0036] The tooling body 2 has a first wall 2-1, a second wall 2-2 arranged opposite to the first wall 2-1, and a locking screw 2-3 threadedly connected to the first wall 2-1; the locking screw 2-3 can move between a first position and a second position relative to the second wall 2-2, forcing the pitot tube located between the first wall 2-1 and the second wall 2-2 to rotate along its axis relative to the wind speed transmitter. In the second position, the plane where the axis of the first tube 3 and the axis of the second tube 4 of the pitot tube are located is parallel or substantially parallel to the plane where the table 1 is located, that is, the plane where the axis of the first tube 3 and the axis of the second tube 4 of the pitot tube are located is parallel or substantially parallel to the end face of the wind speed transmitter. Compared with the visual method used in the prior art, not only can the parallelism of the pitot tube installation be improved, but also the consistency of the product is relatively high after the pitot tube is installed using the tooling.
[0037] For ease of understanding, an exemplary description is given below:
[0038] In this exemplary description, the plane where the second wall 2-2 is located and the plane where the end face of the locking screw 2-3 is located are both perpendicular or substantially perpendicular to the plane where the table 1 is located. During the movement of the locking screw 2-3 from the first position to the second position, the plane where the end face of the locking screw 2-3 is located is always parallel or substantially parallel to the plane where the second wall 2-2 is located. The plane where the end face of the full pressure end of the first tube 3 is located and the plane where the end face of the static pressure end of the second tube 4 is located are parallel or substantially parallel, and are perpendicular or substantially perpendicular to the plane where the axis of the first tube 3 and the axis of the second tube 4 of the pitot tube are located.
[0039] like Figure 4 As shown, when the locking screw 2-3 is in the first position, the distance from the end face of the full-pressure end of the first tube 3 to the end face of the static-pressure end of the second tube 4 is smaller than the distance from the end of the locking screw 2-3 to the second wall 2-2, so that the pitot tube is conveniently placed between the first wall 2-1 and the second wall 2-2; the plane where the end face of the full-pressure end of the first tube 3 and the plane where the end face of the static-pressure end of the second tube 4 are located are parallel or substantially parallel, and are arranged at an acute angle to the plane where the table 1 is located. At this time, rotate the locking screw 2-3 so that the end face of the locking screw 2-3 contacts the full-pressure end of the first tube 3, and the second wall 2-2 contacts the static-pressure end of the second tube 4, as shown in FIG. Figure 5 As shown; continue to rotate the locking screw 2-3. Since the end face of the locking screw 2-3 is at a certain angle to the end face of the full pressure end of the first tube 3, and the second wall 2-2 is at a certain angle to the end face of the static pressure end of the second tube 4, the locking screw 2-3 and the second wall 2-2 cooperate to force the Pitot tube to rotate along its axis relative to the wind speed transmitter. The rotation direction is Figure 5 Counterclockwise direction shown.
[0040] like Figure 6 , Figure 7 As shown, when the locking screw 2-3 is in the second position, the end faces of the full-pressure end of the first tube 3 and the static-pressure end of the second tube 4 are in contact with the end of the locking screw 2-3 and the second wall 2-2 respectively, and the plane where the end face of the full-pressure end of the first tube 3 and the plane where the end face of the static-pressure end of the second tube 4 are located are both perpendicular or substantially perpendicular to the plane where the table 1 is located. At this time, the plane where the axis of the first tube 3 and the axis of the second tube 4 of the pitot tube are located is parallel or substantially parallel to the plane where the table 1 is located, that is, the plane where the axis of the first tube 3 and the axis of the second tube 4 of the pitot tube are located is parallel or substantially parallel to the end face of the wind speed transmitter.
[0041] like Figure 3 As shown, in some practical applications, the tooling body 2 includes:
[0042] The connecting part 2-4 is installed on the table 1;
[0043] The adjusting portion 2-5 is located on the connecting portion 2-4 and is provided with a groove 2-6 for the full pressure end of the first tube 3 and the static pressure end of the second tube 4 to extend into, thereby forming the first wall 2-1 and the second wall 2-2 on both sides of the groove 2-6. In order to facilitate installation and processing, the connecting portion 2-4 and the adjusting portion 2-5 are integrally formed and are L-shaped as a whole.
[0044] In other practical applications, the installation tool also includes a clamp 5 (such as a C-type clamp) to clamp the connecting parts 2-4 on the table 1. It is more flexible to use: as long as there is a flat table, the tool can be formed without being restricted by the site; in addition, after the tool is used, the tool body 2 is removed and the table 1 can be used for other purposes.
[0045] During the actual operation, the first step is to use the C-clamp 5 to fix the tooling body 2 to the table 1; the second step is to place the wind speed transmitter on the table 1, and the end of the Pitot tube 7 away from the total pressure end and the static pressure end is screwed onto the wind speed transmitter housing 6, and after pre-screwed to the bottom, it is rotated back to a visually parallel state (the air inlet direction of the Pitot tube is visually parallel to the end face of the wind speed transmitter, that is, the plane where the axes of the first tube and the second tube on the Pitot tube are visually parallel to the end face of the wind speed transmitter); the third step is to insert the free end of the Pitot tube 7 (the end with the total pressure end and the static pressure end) into the tooling body 2 (embedded between the first wall and the second wall), and then tighten the locking screws 2-3 to force the Pitot tube 7 to rotate along its axis relative to the wind speed transmitter housing 6, so that the plane where the axes of the first tube 3 and the second tube 4 of the Pitot tube are parallel or substantially parallel to the plane where the table 1 is located, and finally tighten the locking nut 8. This ensures the parallelism and consistency of the Pitot tube installation, thereby ensuring the accuracy and quality of the product.
[0046] In the above description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed above.
