[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figure 1-2 The embodiments of this utility model include:

[0023] A volume measurement and positioning device for air ducts is detachably mounted on the air duct 1. Its structure includes: a positioning base plate 2, a positioning hole, a fixing component 3, a sealing seat 4, a sealing plug 5, and a sealing head 6.

[0024] The inner wall of the positioning base plate is an arc-shaped structure that matches the air duct. The positioning base plate is fitted onto the outer wall of the air duct by fasteners, and a sealing element (such as a sealing ring or sealing strip) is provided between the positioning base plate and the outer wall of the air duct. The positioning hole is located in the middle of the positioning base plate. One end of the hollow sealing seat is connected to the outer wall of the positioning base plate, and the hollow channel 41 inside the sealing seat is connected to the positioning hole to form a positioning channel for positioning the opening position of the air duct. This allows the opening device to extend into the positioning channel to open the measuring hole 7 on the air duct, improving the efficiency and accuracy of the opening.

[0025] More preferably, the positioning base plate and the sealed seat are integrated into one structure.

[0026] More preferably, the fasteners include cable ties, clamps, and buckles.

[0027] More preferably, the positioning base plate is provided with connection holes 21 for connecting or fixing cable ties. Cable ties are used to secure the positioning base plate to the duct by tightly securing it to the connection holes. Using cable ties for connection makes later replacement or disassembly and maintenance more convenient and adaptable to different installation environments, especially in scenarios where the space around the duct is limited, as cable ties save space and facilitate disassembly and assembly. Depending on the diameter of the duct, the number of cable ties can be appropriately increased or different lengths of cable ties can be selected for fixing.

[0028] The plug head is movably installed inside the measuring hole to seal the measuring hole. The plug head is equipped with a push-pull part to facilitate the insertion and removal of the plug head. The sealing plug is threadedly connected to the sealing seat to seal the positioning channel. The outer end of the sealing plug is equipped with a grip to facilitate the rotation and installation of the sealing plug.

[0030] More preferably, the outer periphery of the sealing plug and the inner wall of the sealing seat are provided with threads, and one end of the sealing plug extends into the hollow channel to be threadedly connected to the sealing seat.

[0031] More preferably, the push-pull component includes a pull cord or a lifting handle, etc.

[0032] More preferably, the sealing plug is provided with a sealing element that connects to the sealing seat, further improving the sealing effect.

[0033] When using the equipment, first use cable ties to fix the positioning base plate to the air duct, so that the positioning channel is aligned with the preset opening position; select a hand drill bit with the same diameter as the anemometer probe, insert the drill bit into the positioning channel and drill a measuring hole in the air duct, and insert the anemometer probe into the air duct to measure; after the measurement is completed, remove the anemometer, insert the sealing head into the measuring hole to effectively ensure that dust cannot enter the air duct; then screw the sealing plug into the positioning channel (or hollow channel) to complete the sealing of the positioning channel and prevent air leakage.

[0034] The beneficial effects of this utility model's air volume measurement and positioning device for air ducts are:

[0035] 1. This product has a simple structure, is easy to operate and disassemble, which can improve the efficiency of drilling and inspection, has good reliability, and is conducive to widespread use;
