Description

Technical Field

[0001] This utility model relates to the field of ultrasonic oxygen concentration measurement technology, specifically to an ultrasonic oxygen concentration meter capable of measuring flow rate. Background Technology

[0002] Ultrasonic oxygen concentration meters are typically not used to directly measure flow rate, but rather primarily to monitor the oxygen concentration in a gas. When ultrasonic technology is mainly applied to flow measurement, it works by measuring the time difference or frequency change of ultrasonic waves propagating through the fluid to estimate the fluid velocity, and thus calculate the flow rate.

[0003] In the prior art, the installation of ultrasonic oxygen concentration meters usually involves connecting the flanges on both sides to the flange at the access end with bolts. However, the above connection method often requires multiple bolts, and the installation space is generally quite small. Consequently, the large number of bolts increases the installation difficulty and reduces the installation efficiency. Therefore, an ultrasonic oxygen concentration meter that can measure flow rate is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an ultrasonic oxygen concentration meter capable of measuring flow rate. It offers advantages such as facilitating the installation of the ultrasonic oxygen concentration meter, thereby reducing its installation difficulty and improving installation efficiency. It solves the problem that in existing technologies, the installation of ultrasonic oxygen concentration meters typically involves connecting the flanges on both sides to the flange at the access end with bolts. However, this connection method often requires multiple bolts, and the installation space is generally quite small, which increases the installation difficulty and reduces installation efficiency due to the large number of bolts.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An ultrasonic oxygen concentration meter capable of measuring flow rate includes a concentration meter body and flanges on both sides. Guide columns arranged in a ring array and adapted to the access flange are fixedly connected to opposite sides of the flanges. A columnar cylinder is fixedly connected to the outer side of the flanges. A worm gear extending into the cylinder wall is rotatably connected to the front side of the columnar cylinder. A drive assembly coaxial with and meshing with the worm gear is provided inside the cylinder wall of the columnar cylinder. Fastening components arranged in a ring array and connected to the drive assembly are provided inside the cylinder wall of the columnar cylinder. The opposite end of the fastening components extends into the cylinder and is adapted to the outer side of the access flange.

[0008] The beneficial effects of this utility model are:

[0009] This ultrasonic oxygen concentration meter, capable of measuring flow rate, involves fitting a cylindrical sleeve around the outside of the inlet flange, inserting guide pins on one side of the flange into the threaded holes of the inlet flange, and then bringing the flange tightly against the inlet flange. An electric wrench rotates the worm gear, which meshes with the drive assembly, causing the drive assembly to rotate. Since the fastening assembly is connected to the drive assembly, it moves to the opposite side, bringing the opposite end of the fastening assembly into contact with the outside of the inlet flange. This ensures a tight fit between the inlet flange and the flange, completing the installation. This method facilitates the installation of the ultrasonic oxygen concentration meter, reducing installation difficulty and improving installation efficiency.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the drive assembly includes a worm gear disk and arc-shaped holes. The worm gear disk, which is coaxial with the cylindrical wall and meshes with the worm head, is rotatably connected inside the cylindrical wall. The worm gear disk has arc-shaped holes arranged in a ring array on its side.

[0012] Furthermore, the fastening assembly includes wedge-shaped sliders and linkage rods. The cylindrical wall of the cylindrical tube is slidably connected with wedge-shaped sliders arranged in a ring array. The opposite ends of the wedge-shaped sliders extend into the interior of the cylindrical tube and are adapted to the outer side of the access flange. The right side of each wedge-shaped slider is fixedly connected with a linkage rod extending into the arc-shaped hole.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by driving the bolt head worm gear to rotate through the electric wrench, the bolt head worm gear meshes with the worm wheel, thereby driving the worm wheel and the arc-shaped hole to rotate. Since the arc-shaped hole is connected to the linkage rod, it drives the wedge-shaped slider to slide to the opposite side inside the cylindrical wall of the cylindrical tube. The opposite end of the wedge-shaped slider contacts the outside of the flange at the access end, which allows the flange to move towards the flange at the access end until the flange at the access end and the flange are tightly fitted, thus completing the installation.

[0014] Furthermore, each of the opposite ends of the guide post is chamfered.

[0015] The advantage of adopting the above-mentioned further solution is that one end of the guide post is chamfered, so that the guide posts on the flange side can be inserted into the threaded holes of the access flange respectively.

[0016] Furthermore, rubber sealing gaskets that are compatible with both the guide post and the access flange are bonded to opposite ends of the flange.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the access end flange and the flange are tightly fitted, the rubber sealing gasket can seal the gap between the access end flange and the flange. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the embodiments, by Figure 1-4 Presented is an ultrasonic oxygen concentration meter capable of measuring flow rate. The present invention includes a concentration meter body 1 and flanges 2 on both sides. Guide columns 3, arranged in a ring array and adapted to the access flange, are fixedly connected to opposite sides of the flanges 2. Columnar cylinders 4 are fixedly connected to the outer sides of the flanges 2. A worm gear 5 extending into the inner wall of the columnar cylinder 4 is rotatably connected to the front side of the columnar cylinder 4. A drive assembly 6, coaxial with and meshing with the worm gear 5, is provided inside the inner wall of the columnar cylinder 4. Fastening assemblies 7, arranged in a ring array and connected to the drive assembly 6, are provided inside the inner wall of the columnar cylinder 4. The opposite ends of the fastening assemblies 7 extend into the inner wall of the columnar cylinder 4 and are adapted to the outer side of the access flange.

[0025] The drive assembly 6 includes a worm gear disk 601 and an arc-shaped hole 602. The worm gear disk 601, which is coaxial with the cylindrical tube 4 and meshes with the worm head 5, is rotatably connected inside the tube wall. The worm gear disk 601 has arc-shaped holes 602 arranged in a ring array on its side.

[0026] The fastening assembly 7 includes a wedge-shaped slider 701 and a linkage rod 702. The cylindrical wall of the cylindrical tube 4 is slidably connected with wedge-shaped sliders 701 arranged in a ring array. The opposite ends of the wedge-shaped sliders 701 extend into the interior of the cylindrical tube 4 and are adapted to the outer side of the access flange. The right side of each wedge-shaped slider 701 is fixedly connected with a linkage rod 702 extending into the arc-shaped hole 602.

[0027] The electric wrench drives the bolt head worm 5 to rotate. Since the bolt head worm 5 meshes with the worm wheel 601, it drives the worm wheel 601 and the arc-shaped hole 602 to rotate. Since the arc-shaped hole 602 is connected to the linkage rod 702, it drives the wedge slider 701 to slide to the opposite side inside the cylindrical wall of the cylindrical tube 4. The opposite end of the wedge slider 701 contacts the outside of the flange at the access end, which allows the flange 2 to move towards the flange at the access end until the flange at the access end and the flange 2 are tightly fitted, thus completing the installation.

[0028] The opposite ends of the guide columns 3 are all chamfered;

[0029] One end of the guide post 3 is chamfered so that the guide posts 3 on one side of the flange 2 can be inserted into the threaded holes of the access flange respectively;

[0030] Both ends of flange 2 are bonded with rubber sealing gaskets 8 that are compatible with guide post 3 and access flange.

[0031] When the inlet flange and flange 2 are tightly fitted, the rubber sealing gasket 8 can seal the gap between the inlet flange and flange 2.

[0032] Working principle:

[0033] Step 1: Place the cylindrical tube 4 on the outside of the flange at the access end, and insert the guide pins 3 on one side of the flange 2 into the threaded holes of the flange at the access end.

[0034] Step 2: Drive the bolt head worm 5 to rotate by the electric wrench. Since the bolt head worm 5 meshes with the worm wheel 601, it drives the worm wheel 601 and the arc-shaped hole 602 to rotate. Since the arc-shaped hole 602 is connected to the linkage rod 702, it drives the wedge slider 701 to slide to the opposite side inside the cylindrical wall of the cylindrical tube 4.

[0035] Step 3: The opposite end of the wedge slider 701 contacts the outside of the access flange, which allows the flange 2 to move toward the access flange until the access flange and the flange 2 are tightly fitted. The rubber sealing gasket 8 seals the gap between the access flange and the flange 2, and the installation is completed.
