Description

Technical Field

[0001] The utility model relates to the technical field of flowmeters, in particular to a portable, protective and flow velocity measurement integrated device suitable for large flow in open channels. Background Art

[0002] At present, the main methods for monitoring seepage flow are the volumetric method, the water-measuring weir method, and the flow velocity method. The volumetric method is applicable to cases where the seepage flow is less than 1 L / s; the water-measuring weir method is applicable to cases where the seepage flow is 1 to 300 L / s; when the seepage flow is greater than 300 L / s, the flow velocity method is often used. For open channels with large flows greater than 300 L / s, the buoy method, conventional flow meter method, or Doppler flow meter method are currently commonly used to measure flow. Because the buoy method is susceptible to external interference, the measurement accuracy is not high; and although the Doppler flow meter method has a high degree of automation, it is expensive. Therefore, the conventional flow meter method is widely used in actual engineering. This method obtains the flow velocity at a typical location of the monitoring section by measuring, and then calculates the seepage flow of the monitoring section. However, when using the conventional flow meter method to measure flow, there are the following problems: First, a water gauge is required to measure the water depth of the open channel, and then the flow meter is arranged at the typical water depth to measure the flow, which is a cumbersome operation process; Second, the open channel water flow inevitably suspends debris such as aquatic plants, which easily entangles the flow meter and affects the reliability of the flow velocity measurement. To address these problems, this patent provides a portable-protection-flow velocity measurement integrated device that integrates a water gauge, flow meter and protection. This can simplify the operation process, quickly determine the placement of the flow meter, and at the same time avoid the influence of debris suspended in the water flow on the flow meter measurement. Utility Model Content

[0003] The utility model aims to solve the problem that suspended matter in water easily entangles the propeller of the current meter, solves the problem that suspended matter in water easily blocks the protective net, and solves the problem that the water flow in the protective net affects the velocity measurement accuracy of the current meter.

[0004] In view of the defects existing in the prior art, in order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A portable integrated device for large flow in open channels, protection and flow velocity measurement, comprising a plurality of scale rods, wherein each adjacent scale rod is fixedly connected to form a total scale rod, the outer wall of the total scale rod is sleeved with the inner wall of a sleeve of a linear sliding component, the outer wall of the sleeve is fixedly connected to a plurality of clamps of the protection component, each clamp is provided on both sides with hooks, the hook of each hook is clamped with a frame ring on one side of a protection net sleeve, a plurality of clamps are provided on the other side of each protection net sleeve, each clamp is buckled with the side wall of one side of a protection frame, the frame rod on the other side of the protection frame is fixedly welded to the clamp, and the outer wall of the sleeve is also fixedly connected to a flow meter.

[0006] The center of the velocity meter is a mounting hole, which fits the outer wall of the fixed connecting sleeve.

[0007] The last scale rod at the bottom end of the scale main rod is fixedly connected to the lower base plate. The scale rod is made of iron, and the base plate is a magnet for adsorbing the scale rod.

[0008] Tightening bolts are installed on multiple wall holes of the sleeve of the linear sliding component, and each tightening bolt passes through and is fixedly connected to the side wall of the linear sliding component and is fixedly connected to the outer wall of the scale main rod.

[0009] A spiral rod is provided on the top of each scale rod, and a spiral hole is provided on the bottom of each scale rod. The spiral rods and spiral holes of each adjacent scale rod are spirally fixedly connected to form a total scale rod.

[0010] The speed measuring head propeller mounting seat of the current meter is located on a side close to the protective component.

[0011] The clamp comprises two semicircular clamping rings, each of which is provided with wall holes at both ends, and a hook hole at the tail of the hook is fixedly connected to each of the two wall holes by screws and nuts.

[0012] The wire diameter of the protective net is 1.5-2 mm.

[0013] The mesh size of the protective net is 1.5 cm to 2.5 cm.

[0014] There are two protective net sleeves in total, and the angle between the two protective net sleeves is 60°~80°.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The current meter protection device and the current meter underwater positioning device are equipped with a mesh protection structure to protect the current monitoring instrument, so as to avoid the problem of water plants entangled in the current meter during use, causing structural damage and affecting the monitoring work, reduce the interference and damage of foreign objects in the water to the instrument itself, and improve the protection effect in the flow monitoring of water conservancy projects;

[0017] 2. The protective structure of the current meter protection device and the current meter underwater positioning device can move up and down with the sleeve, and can be opened and closed by a hook.

[0018] 3. The current meter protection device and the current meter underwater positioning device are equipped with a scale rod, which can locate the current meter underwater and intuitively display the underwater depth position of the current meter. The specific position information of the current meter can be accurately grasped under different water levels to ensure the accuracy of the measurement position.

[0019] 4. There are two protective nets in each set, and the angle between the two protective nets is 60°~80°; if the angle is too low, it will easily affect the accuracy of the flow meter's speed measurement, and if the angle is too large, the aquatic plants will be accumulated on the protective net by the flow, causing the protective net to be blocked.

[0020] 5. The wire diameter of the protective net 504 is 1.5-2mm. The mesh size of the protective net 504 is 1.5-2.5cm. A mesh size that is too large will not be able to prevent water plants and gravel from entering, while a mesh size that is too small will affect the flow rate measured by the current meter.

[0021] 6. The velocity meter is a customized velocity meter with a total length of 8~10cm. The structure and working principle of the velocity meter are similar to those of the LS20B velocity meter on the market, but it is smaller in size, making it more suitable for this device and more suitable for open channel flow measurement.

[0022] 7. The distance between the connection between the flow meter and the sleeve and the protective net clamp is controlled at 30cm~40cm, so as to reduce the transmission of the interference of the protective net 504 on the water flow state and improve the measurement accuracy.
