Description

Technical Field

[0001] The utility model relates to the technical field of liquid flow measurement, in particular to a device for automatically measuring liquid flow. Background Art

[0002] As is known, a pulse irrigator is a irrigating device that uses pulsating water flow under a certain pressure to irrigate wound tissues. The oscillation of the pulse water flow causes bacteria and foreign matter in the wound to be separated from the tissue by bouncing, thereby achieving the purpose of thorough debridement. Pulse irrigators can be used for wound debridement, soft tissue debridement, and cleaning of surgical sites. Therefore, there are certain requirements for the flow rate. The flow rate per minute during operation needs to be monitored, so the flow rate needs to be measured by a device that automatically measures the liquid flow rate.

[0003] For example, the patent application with the publication number CN204115794U and the publication date of January 21, 2015, entitled "A flowmeter for automatic and accurate measurement of rare earth liquids", belongs to the field of liquid flow measurement, and specifically relates to a flowmeter for automatic and accurate measurement of rare earth liquids. In order to overcome the shortcomings of the prior art in measuring the flow of rare earth liquids inaccurately, the patent provides such a flowmeter for automatic and accurate measurement of rare earth liquids, including a rough measurement device and a fine measurement device, the rough measurement device includes a rough measurement liquid inlet, a valve, a vertical cone tube, a float and a rough measurement liquid outlet, and the fine measurement device includes a fine measurement liquid inlet, an overflow port, a partition, a square container, a fine measurement liquid outlet and a float switch. The patent achieves the effect of accurately measuring the flow of rare earth liquids.

[0004] In the prior art, when liquid flushers are measuring flow, the measurement is mostly done manually, where the liquid is flushed into a measuring cylinder through a tube, and a stopwatch is used to record the reading of the measuring cylinder every minute, thereby obtaining the real-time flow of the liquid. This measurement method is labor-intensive, and the staff is easily distracted and misreads the reading of the measuring cylinder, resulting in inaccurate measurement results. When large-scale measurements are required, the measurement work is relatively cumbersome, making the measurement work intensive and inefficient. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a device for automatically measuring liquid flow, including a base plate 1, a curved pipe 2 and a water tank 3, wherein the water tank 3 is installed on the base plate 1, and the top of the water tank 3 is connected to one end of the curved pipe 2, and also includes an intelligent digital electronic scale 4, wherein the intelligent digital electronic scale 4 is installed on the base plate 1, and the water tank 3 is placed on the intelligent digital electronic scale 4.

[0024] Specifically, the water tank 3 is a liquid storage container, the curved pipe 2 is a liquid delivery pipe body, and the curved pipe 2 has a certain elasticity, so that the curved pipe 2 can be bent all the time and can also be straightened. The middle part of the curved pipe 2 is an "S"-shaped curved shape, and the curved section of the curved pipe 2 is divided into a first curved portion 21 and a second curved portion 22. Since the water tank 3 is placed on the smart digital electronic scale 4, the smart digital electronic scale 4 can measure the liquid volume in the water tank 3 in real time and record the flow rate of the liquid per minute. The smart digital electronic scale 4 is electrically connected to the tablet computer 5, that is, the tablet computer 5 is connected to the smart digital electronic scale 4 through a data cable, and the tablet computer 5 can monitor the smart digital electronic scale 4. The volume and time data on the scale 4 are sorted out and a data table is exported to realize automatic recording of the data of the volume change per minute in the water tank 3. When the liquid flow needs to be detected, the liquid is transported to the water tank 3 through the curved pipe 2. When the liquid flows into the curved pipe 2, the liquid first passes through the first curved portion 21 of the curved pipe 2. Since the first curved portion 21 is a curved surface, the liquid stays in the first curved portion 21 for a certain period of time (that is, a part of the liquid is temporarily stored in the first curved portion 21), so that the first curved portion 21 performs a certain buffering treatment on the liquid transportation, so that the liquid level needs to be higher than the connection between the first curved portion 21 and the second curved portion 22. The liquid will flow from the elbow 2 into the water tank 3 only when the position is reached. The intelligent digital electronic scale 4 records the volume change in the water tank 3 per minute in real time, and can automatically measure and process the liquid flow, thereby reducing the labor intensity of the staff and improving the efficiency of liquid flow detection. In addition, the first bend 21 of the elbow 2 performs a certain buffering treatment on the liquid to prevent the liquid from flowing directly into the water tank from the high position of the elbow 2, thereby affecting the measurement results of the water tank 3 and the intelligent digital electronic scale 4. In the prior art, when the liquid flusher performs flow measurement, most of them are measured manually, by flushing the liquid into the measuring cylinder through the tube body, and using a stopwatch to record the time. , the reading of the measuring cylinder is recorded every minute, and the real-time flow rate of the liquid is obtained. This measurement method has a large workload, and the staff is easily distracted and misreads the reading of the measuring cylinder, which leads to inaccurate measurement results. When a large number of measurements are required, the measurement work is relatively cumbersome, making the measurement work intensity high and the efficiency low; in this embodiment, the liquid is transported to the water tank 3 through the curved pipe 2, and the liquid volume in the water tank 3 is recorded in real time by the intelligent digital electronic scale 4, which can automatically detect the liquid flow, improve the accuracy of the liquid flow measurement results and the detection efficiency, and reduce the labor intensity of the staff's detection work.

[0025] In another embodiment provided by the utility model, a straight plate 6 is installed on the bottom plate 1; an L-shaped plate 7 is slidably installed on the straight plate 6, and the L-shaped plate 7 consists of a vertical plate 71 and a horizontal plate 72, the vertical plate 71 is parallel to the straight plate 6, and the horizontal plate 72 is perpendicular to the straight plate 6; a through groove 8 is opened on the straight plate 6, and the vertical plate 71 of the L-shaped plate 7 and the through groove 8 are connected by a threaded rod 9; the threaded rod 9 passes through the through groove 8 and the vertical plate 71; one end of the threaded rod 9 is pressed against the outer wall of the straight plate 6, and the other end of the threaded rod 9 is connected by a nut 10, and the nut 10 is pressed against the outer wall of the vertical plate 71; a liquid inlet pipe body 11 is rotatably installed on the horizontal plate 72; the liquid inlet pipe body 11 is threadedly sealed with the other end of the bent pipe 2.

[0026] Specifically, when it is necessary to detect the liquid flow rate, the staff connects the curved pipe 2 with the liquid inlet pipe body 11 through threads, so that the liquid can be transported from the liquid inlet pipe body 11 and the curved pipe 2 to the water tank 3. The straight plate 6 and the bottom plate 1 are vertically arranged, and a scale value is set on the straight plate 6 to record the distance that the L-shaped plate 7 slides on the straight plate 6 (that is, the height difference between the liquid inlet and outlet ends and the water tank 3 can be directly recorded on the scale value). When detecting the liquid flow rate, it is necessary to adjust the height difference between the liquid inlet end and the water tank 3 (that is, the height distance between the liquid inlet end and the liquid entering the water tank 3) to record the data changes between the height difference between the liquid inlet end and the water tank 3 and the liquid flow rate, and then obtain the height difference between the liquid inlet end and the water tank 3 and the liquid flow rate. The data relationship between the volume flow rate and the volume flow rate, when it is necessary to adjust the height between the liquid inlet end and the water tank 3, the staff unscrews the nut 10 out of the threaded rod 9, and then adjusts the position of the threaded rod 9 and the L-shaped plate 7 in the through groove 8, and then adjusts the height difference between the L-shaped plate 7 and the water tank 3 (due to the threaded sealing connection between the curved pipe 2 and the liquid inlet pipe body 11, and the liquid inlet pipe body 11 is installed on the L-shaped plate 7), and then adjusts the height difference between the liquid inlet end and the water tank 3, and then detects the liquid flow rate in the curved pipe 2 through the intelligent digital electronic scale 4 and the tablet computer 5, which can detect the height difference and liquid flow rate data between the liquid inlet end and the water tank 3 in real time, can autonomously adjust the height difference between the liquid inlet end and the water tank 3, can adapt to the measurement of different height requirements, and has a wide range of measured heights.

[0027] In another embodiment provided by the utility model, the end portion of the curved pipe 2 connected to the water tank 3 is a concave structure 12, that is, an annular baffle is provided in the middle of the curved pipe 2. Specifically, since the annular baffle is provided in the curved pipe 2, the annular baffle performs buffering treatment on the liquid flowing through the curved pipe 2, which can effectively reduce the impact of the liquid on the water tank 3, so that the liquid can unload the impact force of the liquid in the curved pipe 2, making the measurement result more accurate and avoiding the measurement data deviation caused by the impact force of the liquid.

[0028] In another embodiment provided by the present invention, a guide piece 13 is provided in the middle of the inner wall of the curved pipe 2, one end of the guide piece 13 is connected to the inner wall of the curved pipe 2, and the other end of the guide piece 13 is disconnected from the inner wall of the curved pipe 2. Specifically, the guide piece 13 is provided at the top of the first bend 21 of the curved pipe 2, and the first bend 21 can collect and process the liquid. In the process of the liquid flowing into the curved pipe 2 from the top of the curved pipe 2, the liquid first passes through the guide piece 13. Since one end of the guide piece 13 is connected to the inner wall of the curved pipe 2, and the other end of the guide piece 13 is disconnected from the inner wall of the curved pipe 2, the guide piece 13 is connected to the inner wall of the curved pipe 2 at one end to block the liquid, and the liquid flows through the end of the guide piece 13 that is disconnected from the inner wall of the curved pipe 2, so that the liquid flows from the curved pipe 2. The inner wall of the tube 2 flows into the first bend 21, and the liquid in the bend 2 is buffered by the guide member 13, and the guide member 13 changes the flow direction of the liquid so that the liquid can flow into the first bend 21 along the inner wall of the bend 2, so that the liquid will not directly enter the first bend 21 from the liquid inlet end of the bend 2, but flows into the first bend 21 from the inner wall of the bend 2, so that the liquid will not affect the first bend 21, and the liquid level needs to be higher than the connection position of the first bend 21 and the second bend 22, and the liquid will flow from the bend 2 into the water tank 3, which can effectively reduce the impact of the liquid on the water tank 3, so that the liquid can remove the impact force of the liquid inside the bend 2, so that the measurement result is more accurate, and the measurement data deviation caused by the impact force of the liquid is avoided.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
