Description

Technical Field

[0001] The utility model relates to the technical field of water measuring devices, in particular to an open channel water measuring device. Background Art

[0002] A flow meter is a device specifically used to measure the velocity of water flow in an open channel. A common flow meter is a flow meter, also known as a flow sensor. Flow meters determine the flow rate of water in an open channel by using different measurement principles. The following are several common types of flow meters: buoy method, electromagnetic method, ultrasonic method, and laser beam method. These flow meters have their own advantages and applicable scopes. The specific selection should be determined based on actual needs, flow range, and accuracy requirements.

[0003] The prior art provides a monitoring device for measuring water in an open channel of an irrigation area (Announcement No.: CN212110148U), which includes a base, a pole fixedly connected to the upper surface of the base, a support plate fixedly connected to the top of the pole, a group of symmetrical support rods fixedly connected to the upper surface of the support plate, and a computer display screen fixedly connected to the side of the two support rods close to each other. The monitoring device for measuring water in an open channel of an irrigation area can make the pole stand more stably on the riverbed of the open channel by providing a base, so as to prevent the pole from tipping over under the impact of the water flow, and the radar pulse level meter can be set up to transmit electromagnetic pulse waves to encounter the water medium through the radar, and part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path, and the distance between the transmitter and the surface of the measured water medium is proportional to the time between the pulse waves, and the liquid level height is calculated, which is calculated and stored by the flow integrator, so as to conveniently calculate the flow volume of the open channel.

[0004] However, the device still has the following defects:

[0005] When the device is in use, if the water level is too high, it will not be usable due to the fixed height of the device. The device measures the height of the water surface and then calculates the flow rate. However, when there are bubbles or other debris on the water surface, it will affect the accuracy of the measurement. Therefore, we need to propose an open channel water measuring device.

DETAILED DESCRIPTION

[0026] The detection machine 8 includes a radar pulse level meter, a battery, and a flow integrator. When the control switches of the radar pulse level meter and the flow integrator are turned on, the electromagnetic pulse wave emitted by the radar encounters the water medium. Part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The water level height is calculated, and the water flow is calculated by the flow integrator, and the data is stored.

[0027] Exemplarily, the filter assembly 5 includes a floating plate 51, the floating plate 51 is slidably connected to the outer side of the benchmark 3, the floating plate 51 is slidably connected to the mounting plate 52 inside, the upper end of the mounting plate 52 is fixedly connected to the filter frame 53, the floating plate 51 is slidably connected to the inner side of the floating plate 51, the limiting rod 54 is slidably connected to the mounting plate 52, and a tension spring 55 is arranged on the outer side of the limiting rod 54.

[0028] Preferably, the lifting assembly 6 includes a mounting groove 61, the mounting groove 61 is opened inside the benchmark 3, a motor 62 is fixedly connected inside the mounting groove 61, the motor 62 is electrically connected to the computer control screen 11, and a screw 63 is fixedly connected to the output shaft of the motor 62.

[0029] Specifically, one end of the tension spring 55 is fixedly connected to the floating plate 51 , and the other end of the tension spring 55 is fixedly connected to the fixing ring 57 .

[0030] Through the design of the tension spring 55 , the tension spring 55 uses the tension force to control the position of the limiting rod 54 through the fixing ring 57 , so that the limiting rod 54 is stuck in the mounting plate 52 .

[0031] In this embodiment, a mounting shell 56 is fixedly connected to the outer side of the floating plate 51 , and the mounting shell 56 is slidably connected to the limiting rod 54 .

[0032] On the other hand, a fixing ring 57 is fixedly connected to the outer side of the limiting rod 54 , and the fixing ring 57 is slidably connected to the mounting shell 56 .

[0033] Through the design of the limiting rod 54 , after passing through the floating plate 51 , the limiting rod 54 is stuck inside the mounting plate 52 , thereby limiting the mounting plate 52 and preventing the mounting plate 52 from moving.

[0034] It is worth mentioning that the outer side of the screw rod 63 is connected to a moving rod 64 via a thread, and the moving rod 64 is slidably connected to the marking rod 3 .

[0035] Through the design of the screw rod 63 , the screw rod 63 controls the moving rod 64 to rise and fall by generating a threaded motion with the moving rod 64 .

[0036] It is worth noting that a limiting plate 65 is fixedly connected inside the installation groove 61 , and the limiting plate 65 is in contact with the moving rod 64 .

[0037] Through the design of the limiting plate 65 , the limiting plate 65 limits the moving rod 64 when the moving rod 64 moves to the lowest position.

[0038] Working principle: When the utility model is used, the base 1 is fixed at the use position by the fixing nail 4, and the height of the device is adjusted according to the water level. The motor 62 is turned on through the computer control screen 11, and the motor 62 drives the screw 63 to rotate. The screw 63 controls the rise and fall of the moving rod 64 through the threaded movement between the motor 62 and the moving rod 64. The moving rod 64 controls the position of the mounting rod 7 and each component on the mounting rod 7, so that the detection machine 8 and other components are always on the water surface. The detection machine 8 works, and the control switch of the radar pulse level meter and the flow totalizer is turned on through the computer control screen 11. After the radar transmits an electromagnetic pulse wave and encounters the water medium, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The water level height is calculated, and the water flow is calculated through the flow totalizer, and the data is stored and finally displayed on the computer control screen 11, which is convenient for personnel to observe the results;

[0039] When water flows through the device, the water flow drives the floating plate 51 to rise, and the mounting plate 52 is installed inside the floating plate 51. The mounting plate 52 rises to the water surface with the floating plate 51, and the filter frame 53 filters the impurities on the water surface to prevent the impurities from flowing to the bottom of the detection machine 8 and affecting the use of the detection machine 8. At the same time, the mounting plate 52 blocks the bubbles on the water surface to prevent the bubbles from affecting the detection results of the detection machine 8. The floating plate 51 changes with the water surface height. During the transportation process after use before and after use, the limit rod 54 can be pulled out to release the limit on the mounting plate 52, and the mounting plate 52 can be taken out, so that the filter frame 53 and the mounting plate 52 are transported separately from the device to avoid damage to the filter frame 53. During installation, the mounting plate 52 is inserted into the floating plate 51, and the limit rod 54 is loosened. The tension spring 55 uses the tension to control the position of the limit rod 54 through the fixing ring 57, so that the limit rod 54 is stuck in the mounting plate 52 to limit the mounting plate 52.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
