Description

Technical Field

[0001] This utility model relates to the field of pipe gallery flow measurement technology, specifically a flow measurement device for pipe galleries. Background Technology

[0002] In existing pipe gallery flow measurement operations, Doppler flow meters are commonly used for measurement. Doppler flow meters are effective tools for measuring dirty and turbid liquids containing scattering bodies such as solid particles or bubbles. They are a type of ultrasonic flow meter and are particularly suitable for measuring liquids containing appropriate amounts of solid particles, bubbles, or emulsions, such as sewage, mud, slurry, pulp, and chemical solutions. Existing Doppler flow meters are usually fixed using mounting plates.

[0003] The existing solution has the following problems: Doppler flow meters are usually fixed to the surface of the mounting plate using a limiting ring, and the limiting ring is usually fixed with bolts. The bolts are subjected to water flow erosion in the pipe gallery for a long time, which can easily cause corrosion, stripping and other problems, making it inconvenient to maintain the Doppler flow meter.

[0004] Based on this, a flow metering device for utility tunnels is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-3 As shown, a flow metering device for a pipe gallery includes a fixing plate 102 connected to the inner wall of the gallery 101. A fixing ring 103 is mounted on the fixing plate 102, limiting a Doppler flow meter 104. A transmission line 105 is provided at the rear end of the Doppler flow meter 104, connecting to a processor 106. A quick-release mechanism is provided between the fixing ring 103 and the fixing plate 102. The quick-release mechanism includes a fixing sleeve 201 fixedly connected to the surface of the fixing ring 103, and a lock is provided on the fixing sleeve 201. The fixed structure provides installation conditions for the Doppler flow meter 104 through the fixing plate 102 and the fixing ring 103. The Doppler flow meter 104 sensor emits a beam of ultrasonic waves of a fixed frequency into the liquid flowing in the pipe. During the propagation of the ultrasonic waves, they are scattered when they encounter suspended particles, bubbles or interfaces in the fluid. The sensor receives the ultrasonic wave signals that are scattered back. The electronic unit inside the instrument calculates the difference between the transmitted frequency and the received frequency to obtain the Doppler frequency shift. The processor 106 calculates the flow velocity component in that direction based on the Doppler frequency shift to complete the flow measurement operation of the pipe gallery.

[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the locking structure includes a slide rail 202. The inner wall of the fixed sleeve 201 is provided with a plurality of slide rails 202. The slider 203 is slidably connected to the slide rail 202. The surface of the slider 203 is fixedly connected to a trigger component. The slide rail 202 provides sliding conditions for the slider 203. The sliding of the slider 203 in the slide rail 202 provides conditions for locking or unlocking the fixed ring 103.

[0030] In one embodiment, such as Figure 4 and Figure 5As shown, the triggering component includes a button 204, a slider 203 is fixedly connected to the button 204, a guide sleeve 205 is provided on the inner wall of the button 204, a guide groove is provided in the middle of the guide sleeve 205, the guide sleeve 205 slides in contact with the sliding post 206, and a locking element is provided on the sliding post 206. The button 204 provides a fixing condition for the guide sleeve 205, and the guide groove on the guide sleeve 205 provides guidance for unlocking or locking.

[0031] In one embodiment, such as Figure 4 and Figure 5 As shown, the locking component includes a locking block 207, which is fixedly connected to the lower end of the sliding column 206. The surface of the fixing plate 102 is provided with a fixing seat 301, and the fixing seat 301 is provided with a locking groove that matches the locking block 207. The side of the sliding column 206 is provided with a transmission unit. The sliding column 206 rotates within the locking block 207, which drives the locking block 207 to rotate. The locking block 207 rotates within the fixing seat 301, thereby locking or unlocking the fixing seat 301.

[0032] In one embodiment, such as Figure 6 and Figure 7 As shown, the transmission unit includes a guide block 208, the guide block 208 is fixedly connected to the side of the sliding column 206, the guide block 208 is slidably connected to the guide groove, and a spring unit is provided at the upper end of the sliding column 206. The spring unit moves up and down through the button 204, the button 204 drives the guide sleeve 205 to move up and down, the guide sleeve 205 drives the guide block 208 to move through the guide groove, and the displacement of the guide block 208 in the guide groove drives the sliding column 206 to rotate, thus providing power for the movement of the sliding column 206.

[0033] In one embodiment, such as Figure 6 and Figure 7 As shown, the spring unit includes a spring 209. One end of the spring 209 is fixedly connected to a rotating plate, and the rotating plate is rotatably connected to a sliding column 206. The other end of the spring 209 is fixedly connected to a button 204. During the rotation of the sliding column 206, the spring 209 continuously provides pressure to the rotating plate. The rotating plate is rotatably connected to the sliding column 206, and the rotating plate continuously provides downward pressure to the sliding column 206, so that the guide block 208 fits tightly against the guide groove for convenient transmission.

[0034] The above embodiments disclose a flow metering device for pipe racks. A slide rail 202 provides sliding conditions for a slider 203. The sliding of the slider 203 within the slide rail 202 provides conditions for locking or unlocking the fixing ring 103. Pressing a button 204 causes it to move up and down, which in turn moves a guide sleeve 205. The guide sleeve 205 moves a guide block 208 through a guide groove. The guide block 208's displacement within the guide groove causes the sliding column 206 to rotate, providing power for its movement. During the rotation of the sliding column 206, a spring 209 continuously provides pressure to a rotating plate. The rotating plate rotatably connects to the sliding column 206, continuously providing downward pressure to the sliding column 206, ensuring the guide block 208 fits snugly against the guide groove for easy transmission. The sliding column 206 rotates within the locking block 207, causing the locking block 207 to rotate within the fixed seat 301, thus locking or unlocking the fixed seat 301. The fixing plate 102 and the fixing ring 103 provide the installation conditions for the Doppler flow meter 104. The Doppler flow meter 104 sensor emits a beam of ultrasonic waves of a fixed frequency into the liquid flowing in the pipe. During propagation, the ultrasonic waves are scattered when they encounter suspended particles, bubbles, or interfaces in the fluid. The sensor receives the scattered ultrasonic wave signals and calculates the difference between the transmitted and received frequencies using the electronic unit inside the instrument to obtain the Doppler frequency shift. The processor 106 calculates the flow velocity component in that direction based on the Doppler frequency shift, thus completing the flow measurement operation in the pipe gallery.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
