Description

Technical Field

[0001] This utility model relates to the field of ultrasonic open channel flow meter technology, and in particular to an installation structure for a time-difference ultrasonic open channel flow meter. Background Technology

[0002] Currently, water flow measurement systems are mainly used for measuring the flow and depth of large rivers, lakes, or important waterways, primarily employing electronic measuring instruments. However, there is limited use for real-time monitoring of water flow in smaller waterways, shallow lakes, ponds, and irrigation canals. Because water flow measurement in irrigation canals involves numerous and dispersed measuring points, a large number of measuring instruments are needed for simultaneous measurement. Using electronic measuring instruments is too expensive and cannot accurately measure flow and volume. Therefore, open channel measuring boxes are required for measuring the flow in smaller waterways.

[0003] However, existing open channel flow measurement boxes have many drawbacks in the installation process. The common installation method requires pre-cutting grooves on both sides of the channel, and then placing and fixing the flow measurement box in the grooves. This process is complicated. Before cutting the grooves, it is necessary to use professional measuring tools for accurate measurement and positioning. During construction, it is necessary to rely on professional equipment such as cutting machines and impact drills to complete the groove cutting work. The whole process consumes a lot of manpower and material resources, which greatly increases the installation cost. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes an installation structure for a time-difference ultrasonic open channel flow meter.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An installation structure for a time-difference ultrasonic open channel flow meter includes a flow measurement box body installed on an open channel. Installation structures for connecting and installing with the open channel are provided on both the left and right sides of the flow measurement box body. Each installation structure includes a transverse groove on the side wall of the flow measurement box body, in which a locking pin slides. A locking hole for inserting the locking pin is provided on the side wall of the open channel. An installation plate is hinged to the upper end of the flow measurement box body. A transmission component is connected within the flow measurement box body and between the installation plate and the locking pin. When the installation plate is flipped to a vertical position, the transmission component drives the locking pin to retract into the transverse groove. When the installation plate is flipped outward to a horizontal position, the transmission component drives the locking pin to extend out of the transverse groove.

[0007] In some embodiments, two transverse grooves are provided at intervals, and a vertical groove is connected to the upper end of each transverse groove, with the transmission assembly disposed in the vertical groove.

[0008] In some embodiments, a hinge seat is provided at the upper end of each of the two vertical slots, and a hinge shaft is provided on the mounting plate. The two ends of the hinge shaft are rotatably mounted on the hinge seats on both sides.

[0009] In some embodiments, the transmission assembly includes a transmission vertical rod that moves up and down within the vertical groove, an inclined guide groove is provided at the lower end of the transmission vertical rod, a movable rod is provided at the inner end of the locking pin and is located within the inclined guide groove, an eccentric cam is provided at both ends of the hinge shaft, and the upper end of the transmission vertical rod abuts against the outer wall surface of the eccentric cam.

[0010] In some embodiments, a spring is provided at the lower end of the transmission rod to keep the transmission rod in an upward orientation.

[0011] In some embodiments, the mounting plate has lifting through holes spaced apart at the front and rear ends.

[0012] In some embodiments, a mounting through hole is provided on the end face of the mounting plate, and the mounting through hole is a strip-shaped structure extending in the front-back direction.

[0013] In some embodiments, a guide rod is provided at the inner end of the transverse groove, and the guide rod is inserted into the inner end of the locking pin to guide the movement of the locking pin.

[0014] In some embodiments, the outer corner of the locking pin is beveled.

[0015] In some embodiments, a sealing ring is provided on the end face of the transverse groove.

[0016] Compared with the prior art, this application has the following advantages:

[0017] This innovative design eliminates the need for traditional slotted installation methods, requiring no complex pre-installation measurements or positioning, and removing the reliance on specialized cutting and hammering during construction. The flow meter body is quickly installed and secured using only locking pins on both sides of the box and locking holes in the open channel sidewall, along with the coordinated operation of the mounting plate and transmission components. During installation, locking holes are first drilled in the open channel sidewall. The flow meter body is then placed inside the channel, and the mounting plate is flipped outwards to a horizontal position, adhering to the end face of the channel. Fasteners are then used to secure the mounting plate to the end face of the channel. Simultaneously, the flipping of the mounting plate, driven by the transmission components, causes the locking pins to extend outwards and insert into the locking holes, ensuring a secure fixation. This innovative design significantly reduces manpower and material resources, effectively lowering installation costs. Attached Figure Description

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1 to 6 The installation structure of the time-difference ultrasonic open channel flow meter presented includes a flow measuring box body 1 installed on an open channel 10. Installation structures for connecting and installing with the open channel 10 are provided on both the left and right sides of the flow measuring box body 1. Each installation structure includes a transverse groove 2 on the side wall of the flow measuring box body 1. A locking pin 3 slides within the transverse groove 2. A locking hole 4 for inserting the locking pin 3 is provided on the side wall of the open channel 10. An installation plate 5 is hinged to the upper end of the flow measuring box body 1. A transmission component is connected within the flow measuring box body 1 and between the installation plate 5 and the locking pin 3. When the installation plate 5 is flipped to a vertical position, the transmission component drives the locking pin 3 to retract into the transverse groove 2. When the installation plate 5 is flipped outwards to a horizontal position, the transmission component drives the locking pin 3 to extend out of the transverse groove 2.

[0027] Based on the above structure, the installation of the flow meter box abandons the traditional slotted installation method, eliminating the need for complex measurement and positioning work before installation, and no longer relying on professional cutting and hammering during construction. The flow meter box body 1 can be quickly installed and fixed simply by the locking pins 3 on both sides of the flow meter box body 1 cooperating with the locking holes 4 on the side wall of the open channel 10, and the coordinated operation of the mounting plate 5 and the transmission component. During installation, the locking holes 4 need to be drilled in the side wall of the open channel 10 first, the flow meter box body 1 is placed in the open channel 10, and then the mounting plate 5 is flipped outward to a horizontal state, so that the mounting plate 5 fits against the end face of the open channel 10. Then, the mounting plate 5 is fixed to the end face of the open channel 10 with fasteners. While the mounting plate 5 is flipped, the locking pins 3 can be driven to extend outward and insert into the locking holes 4 through the action of the transmission component, so as to achieve a firm fixation. This innovative design greatly reduces the input of manpower and material resources and effectively reduces the installation cost.

[0028] It is worth mentioning that when disassembly is required, the mounting plate 5 is flipped into a vertical position, and the transmission component drives the locking pin 3 to retract into the transverse groove 2, so that the flow measuring box body 1 can be removed from the open channel 10.

[0029] See Figure 1 As shown, there are two transverse grooves 2 spaced apart front and back, and a vertical groove 21 is connected to the upper end of each transverse groove 2. The transmission component is located in the vertical groove 21.

[0030] Specifically, two transverse grooves 2 are respectively opened on the side walls of the left and right sides of the flow measuring box body 1 at a certain distance from each other. The upper end of each transverse groove 2 is connected to a vertical groove 21. The corresponding part of the transmission component is installed in the vertical groove 21, and the movement trajectory of the transmission component is restricted by the vertical groove 21 to ensure that it can accurately drive the locking pin 3 to slide in the transverse groove 2.

[0031] Furthermore, a hinge seat 31 is provided at the upper end of each of the two vertical grooves 21, and a hinge shaft 32 is provided on the mounting plate 5. The two ends of the hinge shaft 32 are rotatably mounted on the hinge seats 31 on both sides; so that the mounting plate 5 can be flipped around the hinge shaft 32 as the axis, realizing the conversion between horizontal and vertical forms. The cooperation between the hinge seat 31 and the hinge shaft 32 provides a stable hinge support for the mounting plate 5, ensuring that the mounting plate can be flipped flexibly and smoothly.

[0032] See Figures 4-6As shown, the transmission assembly includes a transmission vertical rod 41 that moves up and down within the vertical groove 21. A slanted guide groove 42 is provided at the lower end of the transmission vertical rod 41. A movable rod 43 is provided at the inner end of the locking pin 3. The movable rod 43 is located within the slanted guide groove 42. An eccentric cam 44 is provided at both ends of the hinge shaft 32. The upper end of the transmission vertical rod 41 abuts against the outer wall of the eccentric cam 44. A spring 51 is provided at the lower end of the transmission vertical rod 41 to keep the transmission vertical rod 41 in an upward position.

[0033] Specifically, the transmission vertical rod 41 is movably installed in the vertical groove 21, and its lower end is provided with an inclined guide groove 42. The inner end of the locking pin 3 is fixedly connected to the movable rod 43, which is inserted into the inclined guide groove 42. The two ends of the hinge shaft 32 are respectively fixedly installed with eccentric cams 44, and the upper end of the transmission vertical rod 41 abuts against the outer wall of the eccentric cam 44. When the mounting plate 5 is flipped outward to a horizontal position, the hinge shaft 32 drives the eccentric cam 44 to rotate, and the eccentric cam 44 pushes the transmission vertical rod 41 to move downward in the vertical groove 21. The transmission vertical rod 41 drives the locking pin 3 to extend out of the transverse groove 2 through the cooperation of the inclined guide groove 42 and the movable rod 43. When the mounting plate 5 is flipped to a vertical position, the eccentric cam 44 rotates in the opposite direction with the hinge shaft 32. Under the action of the spring 51, the transmission vertical rod 41 moves upward, and through the cooperation of the inclined guide groove 42 and the movable rod 43, it drives the locking pin 3 to retract into the transverse groove 2.

[0034] See Figure 1 As shown, there are hoisting through holes 61 spaced apart on the front and back of the end face of the mounting plate 5; during hoisting, the hoisting rope or hook can be passed through the hoisting through holes 61 to hoist the flow meter body 1.

[0035] See Figure 3 As shown, an installation through hole 71 is provided on the end face of the mounting plate 5, and the installation through hole 71 is a strip-shaped structure extending in the front-back direction; when the mounting plate 5 is fixed to the upper end of the open channel, expansion bolts and other fasteners are passed through the installation through hole 71 and connected to the open channel 10, thereby achieving a firm fixation of the flow measuring box body 1.

[0036] See Figure 5 As shown, a guide rod 81 is provided at the inner end of the transverse groove 2. The guide rod 81 is inserted into the inner end of the locking pin 3 and is used to guide the movement of the locking pin 3. The guide rod 81 can guide the movement of the locking pin 3, ensuring that the locking pin 3 always slides smoothly along the direction of the transverse groove 2, avoiding the locking pin 3 from deviating or tilting during the extension and retraction process, and ensuring that the locking pin 3 can be accurately inserted into the locking hole 4 or retracted into the transverse groove 2.

[0037] Furthermore, the outer corner of the locking pin 3 is chamfered at an angle 91. The chamfered design of the outer corner of the locking pin 3 can play a guiding role when the locking pin 3 is inserted into the locking hole 4. Even if there is a slight deviation between the position of the locking pin 3 and the locking hole 4, it can be smoothly inserted by the guidance of the chamfer 91, reducing the difficulty of alignment during installation and improving installation efficiency.

[0038] Furthermore, a sealing ring 92 is provided on the end face of the transverse groove 2. The sealing ring 92 can enhance the sealing between the transverse groove 2 and the locking pin 3, prevent water, mud and other impurities in the open channel from entering the transverse groove 2, avoid impurities from affecting the sliding performance of the locking pin 3 or damaging the transmission components, and extend the service life of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
