Description

A device for acquiring water flow parameters used in water conservancy projects

Technical Field

The utility model relates to the field of water conservancy projects, in particular to a device for acquiring water flow parameters used in water conservancy projects.

Background technique

The water flow parameter acquisition devices commonly used in water conservancy projects can be realized by various sensors and measuring equipment. Common water flow parameters include flow velocity, flow rate, water level, water pressure, etc. Obtaining these parameters can help engineers design, monitor and control water conservancy projects.

A Chinese patent with the announcement number CN218885079U discloses a water level measuring device, including a first measuring tube and a second measuring tube. In the first measuring tube, water flows into the tube through a bottom hole provided at the bottom. The position of the buoy in the tube rises as the water level changes. At the same time, the weight in the second measuring tube sinks downward and contacts a sensor provided at the bottom of the tube to sound an alarm. However, due to the different water environments to be measured, there may be pollution such as duckweed. When the measuring device needs to be taken out of the water, the duckweed that is broken up by the fan blades and enters the first measuring tube with the water flow cannot be effectively cleaned. After multiple uses, when a certain amount of duckweed is accumulated in the tube, the water source pushes the duckweed that is broken up in the tube. These duckweed float on the water surface, which will cause the water surface height to be inconsistent with the actual height, and thus easily lead to inaccurate readings.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

A Chinese patent with the announcement number CN218885079U discloses a water level measuring device, including a first measuring tube and a second measuring tube. In the first measuring tube, water flows into the tube through a bottom hole provided at the bottom. The position of the buoy in the tube rises as the water level changes. At the same time, the weight in the second measuring tube sinks downward and contacts a sensor provided at the bottom of the tube to sound an alarm. However, due to the different environments of the measured waters, there may be pollution such as duckweed. When the measuring device needs to be taken out of the water, the duckweed that is broken up by the fan blades and enters the first measuring tube with the water flow cannot be effectively cleaned. After multiple uses, when a certain amount of duckweed is accumulated in the tube, the water source pushes the duckweed that is broken up in the tube. These duckweed float on the water surface, which will cause the water surface height to be inconsistent with the actual height, and thus easily lead to inaccurate readings.

In order to solve the above problems, please refer to Figures 1-6 for a device for obtaining water flow parameters of a water conservancy project, which includes a bracket 10 and a measuring rope 40. A first measuring cylinder 20 and a second measuring cylinder 30 are equidistantly fixed on both sides of the bracket 10. A plurality of detectors 301 are equidistantly provided on the inner wall of the second measuring cylinder 30 near the bottom. A support frame 202 is provided in the first measuring cylinder 20. The bottom of the first measuring cylinder 20 is open. At least two side slide rails 201 are provided on the outer wall of the first measuring cylinder 20. The side slide rails 201 pass through the bottom of the first measuring cylinder 20. A slider 203 is provided in the side slide rail 201. The inner side surface of the slider 203 is fixedly connected to the side surface of the support frame 202. The outer side surface of the slider 203 is fixedly connected to a horizontally arranged floating plate 204. One end of the measuring rope 40 is connected to the floating block 401 in the second measuring cylinder 30, and the other end is connected to the center of the support frame 202.

When the device is placed in the water to be measured, the floating plate 204 and the support frame 202 provided on the first measuring cylinder 20 will float on the surface of the water because their density is less than that of water. As the water level rises, the floating plate 204 and the support frame 202 will also rise. At the same time, through the connection of the measuring rope 40, the floating block 401 provided in the second measuring cylinder 30 will drop. The second measuring cylinder 30 is provided with several detectors 301 for detection and water cannot enter the second measuring cylinder 30. The floating plate 204 has a larger area and can better drive the support frame 202 to float on the water surface. The side rails 201 and the slider 203 are provided to limit the movement of the floating plate 204 without affecting the water entering the first measuring cylinder 20.

In one implementation case, referring to FIG. 2 , the gravity of the support frame 202 is greater than or equal to the weight of the floating block 401 , and the gravity of the support frame 202 is lower than the buoyancy of water.

When installing the device, the buoyancy of the water in the water area needs to be higher than the gravity of the support frame 202 and the floating plate 204. This can ensure that when the water level rises, the rising water level can drive the support frame 202 and the floating plate 204 to move upward. The gravity of the support frame 202 is greater than the floating block 401 to ensure that when the water level rises and the measuring rope 40 moves, the support frame 202 can always lift the floating block 401 to avoid insufficient gravity causing the floating block 401 to fall to the bottom of the second measuring cylinder 30.

In an implementation case, the interior of the support frame 202 is in a field shape, and the outer side surface of the support frame 202 fits the inner wall of the first measuring cylinder 20 .

By setting the support frame 202, the support frame 202 is in the shape of a Chinese character "田", which avoids the support frame 202 being blocked by attachments and affecting the measurement of the support frame 202, and can avoid blockage by using the side slide rail 201 slotted from the side; after taking the device out of the water, the slider 203 between the support frame 202 and the floating plate 204 slides downward in the side slide rail 201, and the attachments adsorbed on the inner wall of the first measuring cylinder 20 are scraped off, thereby avoiding the accumulation of attachments on the inner wall of the first measuring cylinder 20 affecting the next use.

In the above scheme, the slider 203 between the support frame 202 and the floating plate 204 slides downward in the side slide rail 201, but it is easy to slip because there is no clamping device in the side slide rail 201. In order to solve this problem, please refer to Figures 3 and 5. The lower end face of the side slide rail 201 is provided with a detachable limit block 205, and the limit block 205 includes a fixed plate 2051 and a protruding block 2052. The upper end face of the fixed plate 2051 is fixedly connected to the upper end face of the protruding block 2052, and the protruding block 2052 is inserted into the side slide rail 201.

The setting of the limit block 205 prevents the slider 203 from sliding off the side rail 201 when the device is taken out of the water, and prevents the support frame 202 and the floating plate 204 from falling off the device and affecting the use. The limit block 205 is detachable, which is convenient for cleaning and maintenance of the support frame 202, the slider 203, and the floating plate 204. In addition, the fixing plate 2051 is attached to the lower end surface of the first measuring cylinder 20 and can be connected to the first measuring cylinder 20 by magnetic adsorption.

In one implementation case, referring to FIG. 1 and FIG. 3 , a measuring scale 2011 is fixed to the outer side wall of the first measuring cylinder 20 close to the side slide rail 201 .

When the device is inserted into water, the water level in the first measuring tube 20 can be checked through the side slide rail 201, and the position of the water level can be roughly understood through the measuring scale 2011.

In the above scheme, the slider 203 slides in the side slide rail 201, and the side slide rail 201 may absorb attachments due to the device being immersed in water for a long time. In order to solve this problem, please refer to Figures 2 and 6. The lower end face of the slider 203 is fixed with a protruding tooth 2031, and the protruding tooth 2031 fits the inner wall of the side slide rail 201.

When the device body is taken out of water, if there are attachments adsorbed on the inner side of the side slide rail 201, when the slider 203 slides downward, it drives the protruding teeth 2031 to slide downward, and the teeth of the protruding teeth 2031 can shovel off the attachments on the inner side of the side slide rail 201, thereby preventing the slider 203 from being affected in sliding due to the attachments adsorbed on the inner side of the side slide rail 201.

In the above scheme, the support frame 202 in the first measuring cylinder 20 and the floating block 401 in the second measuring cylinder 30 are connected by the measuring rope 40. The support frame 202 floats up while the floating block 401 drops. However, the measuring rope 40 must be supported and easy to slide and cannot rub against other objects during the sliding process. In order to meet this condition, please refer to Figures 1 and 2. The bracket 10 is T-shaped, and a placement groove 2 101 is provided on the upper end surface of the top of the bracket 10. Rolling members 70 are fixed on both sides of the top of the bracket 10. A placement groove 1 701 is provided in the rolling member 70. The measuring rope 40 is placed in the placement groove 2 101 and the placement groove 1 701. One end of the measuring rope 40 passes through the placement hole provided at the top of the first measuring cylinder 20 and is fixedly connected to the center of the support frame 202. The other end of the measuring rope 40 passes through the placement hole provided at the top of the second measuring cylinder 30 and is fixedly connected to the floating block 401. The measuring rope 40 is placed in the placement groove 1 701 and is in a vertical state when it passes through the placement hole.

The rolling member 70 can be a roller, and both ends of the roller are connected to the bracket 10 by bearings. The outer wall of the roller is provided with a placement groove 1 701 and the top of the bracket 10 is provided with a placement groove 2 101. The measuring rope 40 is placed in the placement groove 1 701. When the measuring rope 40 moves, the rolling member 70 is driven to roll. Through the arrangement of the rolling member 70 and the placement groove 2 101, the bracket 10 provides support for the measuring rope 40 while avoiding the friction between the measuring rope 40 and the bracket 10. The roller is at right angles to the placement holes provided at the top of the first measuring cylinder 20 and the second measuring cylinder 30. When the measuring rope 40 is placed in the placement groove 1 701 and connected to the support frame 202 and the floating block 401, it is in a vertical state, avoiding the friction between the measuring rope 40 and the first measuring cylinder 20 and the second measuring cylinder 30.

In one implementation case, a display screen 50 and an alarm 60 are provided on the outer side wall of the bracket 10 near the second placement slot 101 .

In the above scheme, the support frame 202 and the float 401 are connected by the measuring rope 40. When the support frame 202 rises with the water level, the float 401 descends. When the float 401 descends to the detector 301, the current data can be viewed through the display screen 50, and a warning signal is issued. When the float 401 descends to the second or lower detector 301, the alarm 60 sounds an alarm to prompt the monitor. The alarm 60 can be a buzzer, a warning light, etc.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
