[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1

[0032] The present invention provides an intelligent interception weir overflow flow metering device, comprising: a cylinder 1, one end of which is provided with a water inlet 2, and the other end of which is provided with a water outlet 3; a partition 4, which is located inside the cylinder 1 and divides the space inside the cylinder 1 into a water inlet bin 5 and a water outlet bin 6, the water inlet 2 is located on the bin wall of the water inlet bin 5, and the water outlet 3 is located on the bin wall of the water outlet bin 6; a through hole 7, which is located on the partition 4 and is used to connect the water inlet bin 5 with the water outlet bin 6; a gate 8, which is close to the partition 4 It is connected to one side of the water outlet bin 6, and the opening amplitude of the gate 8 increases with the increase of the water level height difference between the water inlet bin 5 and the water outlet bin 6; a first liquid level gauge 9 is located in the water inlet bin 5, and is used to measure the water level of the water inlet bin 5; a second liquid level gauge 10 is located in the water outlet bin 6, and is used to measure the water level of the water outlet bin 6; a data acquisition processor 11 is used to receive the water level data measured by the first liquid level gauge 9 and the second liquid level gauge 10, and calculate the amount of rainwater discharged according to a preset formula.

[0033] The through hole 7 is located at the center of the partition 4 and is arranged in a rectangular shape.

[0034] Through the above arrangement, the water level of the water inlet tank 5 gradually rises with the increase of water inflow. After rising to a certain height, the gate 8 is opened under the power of the pressure difference between the water inlet tank 5 and the water outlet tank 6, and the opening amplitude changes with the height difference. In this process, the first liquid level meter 9 collects the water level height of the water inlet tank 5 and transmits the data to the data acquisition processor 11, and the second liquid level meter 10 collects the water level height of the water outlet tank 6 and transmits the data to the data acquisition processor 11. The data acquisition processor 11 establishes a calibration relationship between the two liquid levels, the opening size of the gate 8 and the fixed coefficient according to the set flow calculation formula, thereby calculating the overflow volume and automatically calculating the flood discharge volume.

[0035] The end of the partition 4 close to the water outlet bin 6 is connected with a slide bar 12, the gate 8 is slidably connected to the slide bar 12, the slide bar 12 is slidably connected with a sleeve 13, the sleeve 13 is connected to the gate 8, the sleeve 13 is connected with a fixed plate 14, the fixed plate 14 is rotatably connected with a first pulley 15, the inner side wall of the water outlet bin 6 is rotatably connected with a second pulley 16, the first pulley 15 is connected with a steel wire rope 17, the steel wire rope 17 passes around the second pulley 16, and the end of the steel wire rope 17 away from the first pulley 15 is connected with a counterweight 18. Through the above arrangement, when the water level of the water inlet bin 5 gradually decreases, the counterweight 18 drops, the steel wire rope 17 pulls the fixed plate 14 to move toward the through hole 7, the fixed plate 14 drives the sleeve 13 to slide on the slide bar 12, and the sleeve 13 drives the gate 8 to move toward the through hole 7, so that the gate 8 is automatically closed when the water level drops.

[0036] Among them, a pull-wire sensor 23 is connected to the wire rope 17. The pull-wire sensor 23 determines the position of the gate 8 by measuring the tension on the wire rope 17, thereby identifying the degree of opening of the gate 8. It is convenient and efficient, and can effectively calculate the amount of rainwater discharged more quickly and accurately.

[0037] A mounting frame 19 is connected to the inner side wall of the water outlet bin 6, a pair of clamping plates 20 are connected to the mounting frame 19, and the second pulley 16 is located between the two clamping plates 20 and is rotatably connected to the two clamping plates 20. Through the above arrangement, the second pulley 16 is connected to the mounting frame 19 through the two clamping plates 20, which is more convenient and the rotation is smoother.

[0038] The mounting frame 19 is connected with a support frame 21, and the support frame 21 and the mounting frame 19 are arranged in a triangle. Through the above arrangement, the connection between the support frame 21 and the mounting frame 19 is more stable.

[0039] The intelligent interception weir overflow flow metering device provided by the present invention also includes a remote data module, which is used to receive data processed by the data processor. Through the above configuration, the operator can use the remote data module to grasp the amount of rainwater discharged from the flood, which is convenient and fast.

[0040] Among them, the remote data module is a monitoring platform, and the monitoring platform includes a display screen. The display screen is used to display the data collected by the data acquisition processor 11 and the processing results, which is more intuitive.

[0041] The first liquid level gauge 9 is located on the top wall inside the water inlet bin 5, and the second liquid level gauge 10 is located on the top wall inside the water outlet bin 6. Both the first liquid level gauge 9 and the second liquid level gauge 10 are ultrasonic liquid level gauges. Through the above arrangement, the first liquid level gauge 9 and the second liquid level gauge 10 can more accurately measure the height of the liquid level, thereby making the calculation result more accurate.

[0042] The bottom of the outer side wall of the cylinder 1 is connected with a support seat 22, and the support seat 22 contacts the support surface. Through the above arrangement, the arrangement of the support seat 22 makes the cylinder 1 more stable and is not easy to be displaced in the case of heavy rain.

[0043] The cylinder 1 is connected to the support seat 22 by bolts. Through the above arrangement, the connection between the cylinder 1 and the support seat 22 is more stable, and it is also convenient to remove the support seat 22 from the cylinder 1.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
