Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, and in particular to an auxiliary device for detecting wind speed in a clean operating room. Background Technology

[0002] To ensure patient safety, clean operating rooms in medical institutions must regularly monitor the environment. One of the monitoring items is the wind speed or air exchange rate in the operating area. According to GB50333 "Technical Specification for Clean Operating Room Construction in Hospitals," for Class I clean operating rooms, the cross-sectional wind speed at a depth of 1.2m above the floor in the cleanliness level 5 area must be monitored, with the measuring point spacing not exceeding 0.3m. For Class II and Class III clean operating rooms, the average wind speed should be measured, with the measuring point height within 0.1m below the air supply surface, and the measuring point spacing not exceeding 0.3m. During measurement, the instrument's measuring rod must be fixed in place and should not be held by hand.

[0003] Currently, the air velocity in clean operating rooms is mainly measured using a hot-wire anemometer combined with a multi-point grid measurement method. During measurement, the air supply surface is divided into uniform grids, while the cross-sectional air velocity measurement points on the working surface are arranged in a rectangular grid. Grid lines are marked on the ground with tape to determine the coordinates of each measurement point. The anemometer is then placed at the measurement point, with the probe perpendicularly aligned with the air supply surface, and the measurement is taken. This monitoring method is time-consuming and labor-intensive, significantly extending the monitoring time and increasing the workload of staff. Utility Model Content

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] like Figure 1-5 As shown, this utility model discloses an auxiliary device for detecting airflow in a clean operating room. The device includes an L-shaped base 7, with each side of the L-shape being 30cm long. A ball groove 7-1 is machined on the upper surface of one end of one side of the L-shaped base 7, which is used to cooperate with the spherical structure at the lower end of the reinforcing rod 4, achieving the technical effect of supporting the reinforcing rod 4 within a 360-degree range without restricting its rotation.

[0025] A vertical first connecting seat 7-2 is provided at the intersection of the two sides of the L-shaped base. A first fixing hole 7-3 and a first hinge hole 7-3 are arranged from top to bottom on the first connecting seat 7-2. A vertical second connecting seat 7-5 is provided at the end of the other side of the L-shaped base 7. A second fixing hole 7-6 and a second hinge hole 7-7 are arranged from top to bottom on the second connecting seat 7-5. The lower ends of the first support rod 5 and the second support rod 3 are both hinged to their corresponding hinge holes via pins. One support rod is fixedly connected to its corresponding fixing hole via a fixing screw 6, while the other support rod is not connected to its corresponding fixing hole. That is, the two support rods cannot be fixed or hinged simultaneously; one must be hinged and the other fixed.

[0026] An adapter 2 is rotatably mounted on the upper end of the first support rod 5. The adapter can rotate in a vertical plane around the connection point with the first support rod. After rotating to the desired position, it is fixed. An anemometer bracket 1 is mounted on the top of the adapter 2. The outer surface of the adapter 2 is provided with scale lines. An indicator needle corresponding to the position of the scale lines is provided on the anemometer bracket.

[0027] The upper surface of the anemometer bracket is provided with a groove, and elastic blocks are symmetrically arranged in the groove. The elastic blocks can be rubber blocks or springs with one end connected to the groove and the other end connected to the blocks, for securing and fixing the anemometer.

[0028] The first support rod 5 and the second support rod 3 are hinged to each other in an area other than the area connected to the anemometer bracket. The reinforcing rod 4 is hinged to the first support rod 5, and both support rods and the reinforcing rod are telescopic rods.

[0029] When using this device, the first support rod 5 is first fixed to the first connecting seat 7-2 using the fixing screw 6. The second support rod 3 is hinged only through the second hinge hole 7-7. At this time, the first support rod is vertical and retracted to its shortest state. Figure 1 As shown, the anemometer is attached to the anemometer bracket at the top to measure wind speed. The anemometer bracket can also be rotated to measure wind speed in different directions.

[0030] After measurement, remove the fixing screw 6 from the first fixing hole. At this time, the first support rod 5 and the first connecting seat 7-2 are also in a hinged state. Rotate both support rods and the reinforcing rod 4 towards the second connecting seat 7-5. When the second support rod 3 is in a vertical state, fix the second support rod 3 to the second connecting seat 7-5 with the fixing screw 6. At this time, the second support rod 3 is retracted to its shortest length, and the first support rod 5 and the reinforcing rod 4 are extended to their longest length. Figure 3 As shown, the anemometer at the top has moved forward 30cm. Since the anemometer bracket 1 is installed on the upper end of the first support rod 5, the first support rod is tilted at this time. Therefore, the adapter 2 needs to be rotated at a certain angle until the anemometer bracket is horizontal. A level should be installed on the anemometer bracket in advance to indicate the horizontal adjustment status.

[0031] After the new position measurement is completed, using the second connecting seat 7-5 as a fulcrum, rotate the base 180 degrees to achieve the following: Figure 4 As shown in the diagram, the fixing screw 6 is then reinstalled into the first fixing hole 7-3, restoring the first support rod 5 to a vertical position and the second support rod 3 to an inclined position. Figure 5 As shown, the anemometer is at this time Figure 3 It moved forward another 30cm from its original position. This process was repeated.

[0032] After measuring the wind speed in the X direction, rotate the base 90 degrees and repeat the above steps to measure the wind speed in the Y direction.

[0033] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention.
