Description

Technical Field

[0001] The utility model belongs to the technical field of fixing devices, in particular to a Pitot tube wind speed sensor. Background Art

[0002] The sports car test is a new test method that uses the wind generated by a car to study the wind resistance of a structure. Most of the tests use a pitot tube in combination with a wind speed sensor for measurement. The pitot tube wind speed sensor usually needs to be fixed in a certain position. In order to avoid shaking caused by holding the pitot tube with both hands, a fixing device is used to fix the pitot tube. However, most of the current fixing devices are for fixed installation of the pitot tube. Since the measurement of airflow requires measuring different points and finding the average value, the position height of the pitot tube cannot be adjusted according to the actual situation, making it impossible for the pitot tube to detect airflow at different points, thereby reducing the accuracy of airflow detection.

[0003] For example, the existing patent announcement number is: CN203825031U, a pitot tube wind speed sensor for mining, which: "includes a housing, a pitot tube, an aviation socket and a circuit device, the housing includes a front cover and a rear cover; the front cover is a square one-piece with a semi-enclosed structure composed of a front side plate, a left side plate, a right side plate, an upper side plate and a lower side plate, and the rear end of the front cover is open."

[0004] It can be seen that the cited patent document has the problem of inconvenience in adjusting the measurement positioning, which reduces the accuracy. Utility Model Content

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] like Figures 1 to 4 A pitot tube wind speed sensor shown in the figure includes a base 1, which can be moved to a detection location to detect the airflow of a sports car test. A vertical box 2 is fixedly installed on the top surface of the base 1, and both side surfaces of the vertical box 2 are hollowed out. A stopper 15 is fixedly installed on the top surface of the base 1 and on one side of the vertical box 2. A transverse groove 16 is transversely opened on the top surface of the base 1 and on one side of the stopper 15. The inner walls on both sides of the transverse groove 16 are rotatably connected with a threaded shaft 17. One end of the threaded shaft 17 passes through the base 1 and is fixedly connected with a handle, and the handle can be replaced with other driving structures, as long as it can drive the threaded shaft 17 to rotate. A clamping block 18 is provided on the circumferential thread sleeve of the threaded shaft 17. The bottom surface of the clamping block 18 is in frictional contact with the top surface of the base 1. The wind speed sensor is placed on the top surface of the base 1, and one side of the wind speed sensor is against one side of the stopper 15. At this time, the handle is rotated to allow the handle to drive the clamping block 18 to move through the threaded shaft 17, so that the clamping block 18 can be against one side of the wind speed sensor, thereby clamping and fixing the wind speed sensor.

[0027] The top surface of the base 1 and one side of the vertical box 2 are fixedly installed with a chassis 3, which is arranged at a right angle to the chassis 3 and the top surface of the chassis 3 is fixedly installed with a cross block 4, and a sliding sleeve is provided on the top surface of the cross block 4. Slideways for the engagement of the slider 5 can be provided on the two side surfaces of the cross block 4, so that the slider 5 can move on the top surface of the cross block 4, and can also prevent the slider 5 from detaching, and limit blocks can be installed on the two side surfaces of the cross block 4, which can prevent the slider 5 from detaching from the two ends of the cross block 4. The slider 5 is hinged with a connecting plate 6 on one side facing the vertical box 2, and a movable plate 7 is hinged at one end of the connecting plate 6 away from the slider 5. The movable plate 7 is longitudinally arranged in the inner cavity of the vertical box 2, and limit rods 11 are symmetrically installed on the bottom surface of the inner cavity of the vertical box 2. The movable plate 7 is slidably sleeved on the circumferential side of the two limit rods 11. By pushing the slider 5 forward, the slider 5 drives the connecting plate 6 to move. Since the two ends of the connecting plate 6 are respectively hinged to the slider 5 and the movable plate 7, the slider 5 pushes When the connecting plate 6 moves, the connecting plate 6 will push the movable plate 7 to move. Conversely, when the slider 5 is pushed backward, the slider 5 can drive the movable plate 7 to move downward through the connecting plate 6, and through the setting of the two limit rods 11, the movable plate 7 can move along the peripheral side of the limit rods 11 to ensure that the movable plate 7 moves longitudinally. A fixing block 8 is fixedly installed on the side of the movable plate 7 away from the connecting plate 6, and a fixing structure for fixing the Pitot tube is installed on the free end of the fixing block 8. After the wind speed sensor is fixed to the top surface of the base 1, the Pitot tube connected to the wind speed sensor can be fixed in the fixed structure, and through the longitudinal movement of the movable plate 7, the movable plate 7 drives the fixed structure to move longitudinally through the fixing block 8, so that the position of the Pitot tube can be adjusted, so that the Pitot tube can detect the airflow at multiple points, avoid the situation where it is inconvenient to adjust the height and cannot measure the airflow at multiple points, and improve the accuracy of airflow detection in sports car tests.

[0028] The fixing block 8 is installed on the upper half of one side of the movable plate 7, and an arc block 12 is fixedly installed on the side of the fixing block 8 away from the movable plate 7. The fixing structure includes a bolt 13 rotatably connected to one side of the arc block 12 and a pressure block 14 threadedly sleeved on the side of the bolt 13. One side of the pressure block 14 is in friction contact with one side of the fixing block 8, and the diameter of the outer side of the pressure block 14 is smaller than the diameter of the inner cavity of the arc block 12. When the Pitot tube is placed in the inner cavity of the arc block 12, the bolt 13 is rotated to allow the bolt 13 to drive the pressure block 14 to move, so that the pressure block 14 can press the Pitot tube toward one side of the arc block 12, thereby achieving the effect of clamping and fixing the Pitot tube.

[0029] A plurality of locking holes 10 are equidistantly provided on the top surface of the cross block 4, and a locking block 9 for engaging with the locking hole 10 is hingedly connected to the side of the slider 5 away from the connecting plate 6. The locking block 9 can be arranged in an L shape. When the slider 5 moves to a suitable position on the top surface of the cross block 4, the locking block 9 is rotated so that one end of the locking block 9 can enter the inner cavity of the locking hole 10, so that the locking block 9 can be against the inner wall of one side of the locking hole 10, thereby fixing the position of the slider 5.

[0030] Working principle:

[0031] The Pitot tube wind speed sensor places the wind speed sensor on the top surface of the base 1 and is clamped and fixed by the threaded shaft 17, the clamping block 18 and the stopper 15. The Pitot tube connected to the wind speed sensor is fixed in the arc block 12 and the fixed structure, so that the Pitot tube detects the airflow of the sports car test. When it is necessary to detect the airflow at different positions, the slider 5 is pushed to move the slider 5 around the side of the horizontal block 4, so that the slider 5 can push the connecting plate 6 to move. Since the two ends of the connecting plate 6 are respectively hinged with the slider 5 and the movable plate 7, the slider 5 pushes the connecting plate 6. When moving, the connecting plate 6 will push the movable plate 7 to move, and cooperate with the setting of the limit rod 11 to allow the movable plate 7 to move upward in the inner cavity of the vertical box 2, so that the movable plate 7 drives the Pitot tube fixed by the arc block 12 and the fixed structure to move upward through the fixed block 8. Conversely, by pulling the slider 5 backward, the movable plate 7 can be driven to move downward through the connecting plate 6, thereby allowing the Pitot tube to move downward, allowing the Pitot tube to be detected at different locations, avoiding the situation where it is inconvenient to adjust the height and unable to measure the airflow at multiple points, thereby improving the accuracy of airflow detection in sports car tests.
