Description

Technical Field

[0001] The utility model relates to a Parshall flume with an antifreeze effect, in particular to a Parshall flume with an antifreeze effect, belonging to the technical field of water measuring structures in canal water measurement. Background Art

[0002] The Parshall flume is a water measuring facility for hydraulic structures. The standard Parshall flume is divided into three parts: a contraction section a, a throat section b, and a diffusion section c. It has the characteristics of small head loss (about one-fourth of that of a weir), no backwater, and not easy to silt up. It is suitable for large canal bed slopes, and the water measurement accuracy is not affected by sediment concentration.

[0003] At present, there are mainly two forms of application of the Parshall flume in agriculture. One is to arrange the commercially produced Parshall flume on small canals. The other is to use the length ratio of each section of the Parshall flume and the wide-foot support formwork to form it by one-time concrete pouring. Both forms of the Parshall flume are in direct contact with the outside. In cold northern regions such as Xinjiang in China, the problem of soil frost heave is serious, which causes damage to water measurement of buildings. Therefore, the conventional externally installed Parshall flume is deformed under the extrusion of frost-heaved soil. The accuracy of water volume calculation of the Parshall flume depends entirely on the proportionally set component sections. Based on this, in order to achieve accurate agricultural water metering and promote the water price reform in Xinjiang region, it is necessary to solve the problem that the Parshall flume in Xinjiang and other regions is squeezed.

[0004] Therefore, there is an urgent need for a Parshall flume with an antifreeze effect to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a Parshall flume with an antifreeze effect, which can heat the flume body in cold weather, and at the same time has good compressive resistance when encountering soil frost heave, preventing extrusion of the flume body and affecting water flow calculation.

[0006] To achieve the above purpose, the main technical solutions adopted by the utility model include: a Parshall flume with an antifreeze effect, including a flume body, a water level gauge is arranged inside the flume body. The flume body is successively divided into a contraction section, a throat section, and a diffusion section along the water flow direction. Support frames are arranged on the outer end faces of the contraction section and the diffusion section, and a first protection plate on both sides of the flume body is supported by the two support frames. A support rod running through both sides of the flume body is horizontally arranged in the throat section, and buffer plates are arranged at the parts of both ends of the support rod protruding from the flume body. A first power generation mechanism and a second power generation mechanism are respectively arranged above the flume body and at the tail end of the diffusion section. A storage battery and a switch are also supported above the flume body, and a heating plate fitting the outer wall of the flume body is arranged outside the flume body.

[0007] Preferably, the contraction section and the diffusion section are fixed to the support frame by welding, and reinforcing ribs are provided in the support frame and the first protective plate, and the reinforcing ribs in the first protective plate are staggered with each other.

[0008] Preferably, an elastic steel plate is provided between the first protective plate and the outer wall of the trough body, the elastic steel plate and the inner wall of the first protective plate form a cavity, the cavity is also formed between the elastic steel plate and the outer wall of the trough body, and the cavity is filled with thermal insulation cotton.

[0009] Preferably, a plurality of evenly distributed rubber buffer pads are provided on a side of the buffer plate away from the trough body, and a side of the elastic steel plate close to the trough body is in contact with the rubber buffer pads.

[0010] Preferably, the first power generation mechanism is solar power generation, the second power generation mechanism is water flow power generation, the first power generation mechanism and the second power generation mechanism are both used to charge the battery, the battery is used to power the heating plate, and the switch is electrically connected to the heating plate.

[0011] Preferably, the bottom of the solar panel of the first power generation mechanism is a rotationally adjustable structure.

[0012] Preferably, the upper end surface of the trough body is supported by a support frame, the support frame is provided with a hanging ring, and the first power generation mechanism and the battery are arranged on the upper end surface of the support frame.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. When encountering cold weather, the external soil will freeze and swell, exerting pressure toward the trough body. The first protective plate will be depressed inwards under pressure, and the cavity and the internal thermal insulation cotton will be used for preliminary pressure resistance and buffering, and then the elastic steel plate will be used for further pressure resistance and buffering, and the second cavity and the internal thermal insulation cotton will be used for pressure resistance and buffering, and finally the elastic steel plate will be supported by the buffer plate. Since the buffer plate is fixed by a support rod, the buffer plate can be firmly supported to resist pressure, which can effectively improve the antifreeze and anti-pressure effect of the trough body and prevent deformation from affecting the water flow calculation. At the same time, the setting of thermal insulation cotton and heating plate can realize the heating of the trough body, so that the trough body itself has an antifreeze and heating effect, which further prevents the deformation of the trough body in cold weather and affects the water flow measurement accuracy.

[0015] 2. Since the buffer plate is fixed by a support rod, the buffer plate can be firmly supported without exerting pressure on the trough body. The throat section uses a buffer plate to assist in pressure resistance, while the contraction section and the diffusion section use a support frame to assist in pressure resistance, which can effectively improve the antifreeze and pressure resistance of the entire trough body.

Detailed implementation manners

[0023] The following will cooperate with the accompanying drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] As Figures 1-5 shown, the Parshall flume with anti-freezing effect provided in this embodiment includes a tank body 1. A water level gauge 18 is provided in the tank body 1. The tank body 1 includes a contraction section 101, a throat section 102, and a diffusion section 103 that are sequentially divided along the water flow direction. Support frames 2 are provided on the outer end faces of both the contraction section 101 and the diffusion section 103. The first protective plates 3 on both sides of the tank body 1 are supported by the two support frames 2. Among them, the contraction section 101 and the diffusion section 103 are integrally fixed to the support frames 2 by welding, which can improve the strength of the contraction section 101 and the diffusion section 103 and enhance the compressive resistance. Reinforcing ribs 11 are provided in both the support frames 2 and the first protective plates 3. The reinforcing ribs 11 in the first protective plates 3 are arranged in a staggered manner. The arrangement of the reinforcing ribs 11 can improve the support compressive resistance of the first protective plates 3 and the support frames 2;

[0025] A support rod 4 is transversely arranged in the throat section 102 and penetrates both sides of the tank body 1. The portions of both ends of the support rod 4 protruding from the tank body 1 are provided with buffer plates 5.

[0026] Further, such as Figure 1 and Figure 2 As shown, an elastic steel plate 12 is arranged between the first protective plate 3 and the outer wall of the tank body 1, and a cavity 13 is formed between the elastic steel plate 12 and the inner wall of the first protective plate 3. A cavity 13 is also formed between the elastic steel plate 12 and the outer wall of the tank body 1, and the cavity 13 is filled with thermal insulation cotton 14. When the first protective plate 3 is under pressure, it will be concave inward, and the cavity 13 and the internal thermal insulation cotton 14 are used for preliminary pressure resistance and buffering, and then further pressure resistance and buffering are carried out after passing through the elastic steel plate 12, and the second cavity 13 and the internal thermal insulation cotton 14 are used for pressure resistance and buffering, and finally the elastic steel plate 12 is supported by the buffer plate 5. Since the buffer plate 5 is fixed by the support rod 4, the buffer plate 5 can be firmly supported without applying pressure to the tank body 1. The throat section 102 adopts the buffer plate 5 to assist in pressure resistance, while the contraction section 101 and the diffusion section 103 adopt the support frame 2 to assist in pressure resistance;

[0027] Furthermore, Figure 2 As shown, a plurality of evenly distributed rubber buffer pads 15 are arranged on the side of the buffer plate 5 away from the tank body 1, and the side of the elastic steel plate 12 close to the tank body 1 contacts the rubber buffer pad 15. When the elastic steel plate 15 is pressed and contacts the rubber buffer pad 15, the pressure can be further buffered by the rubber material, thereby improving its compression resistance effect.

[0028] A first power generation mechanism 6 and a second power generation mechanism 7 are respectively arranged above the tank body 1 and at the tail end of the diffusion section 103. A battery 8 and a switch 9 are also supported above the tank body 1. A heating plate 10 is arranged on the outside of the tank body 1 and is attached to the outer wall of the tank body 1.

[0029] Further, such as Figures 1-3 As shown, the first power generation mechanism 6 is solar power generation, the second power generation mechanism 7 is water flow power generation, the first power generation mechanism 6 and the second power generation mechanism 7 are both used to charge the battery 8, the battery 8 is used to power the heating plate 10, the switch 9 is electrically connected to the heating plate 10, and multiple power generation methods are adopted to charge the battery 8 at the same time, and reduce the operating load of a single power generation mechanism. The switch 9 is used to control the opening and closing of the heating plate 10, and it is turned off when not in use, which is more energy-saving;

[0030] Furthermore, Figure 1 As shown, the bottom of the solar panel of the first power generation mechanism 6 is a rotating and adjustable structure, which can adjust the lighting direction of the solar panel to ensure a good sunlight exposure effect.

[0031] Further, such as Figure 1As shown, the upper end surface of the tank body 1 is supported by a support frame 16 , and a lifting ring 17 is provided on the support frame 16 . The lifting ring 17 is convenient for lifting the tank body 1 . The first power generation mechanism 6 and the battery 8 are arranged on the upper end surface of the support frame 16 .

[0032] like Figures 1-5 As shown, the principle of the Parshall trough with antifreeze effect provided by this embodiment is as follows: when the trough body 1 is installed, the first protective plates 3 on both sides will fit with the inner side of the water channel. When encountering cold weather, the external soil will freeze and expand, and apply pressure to the trough body 1. The first protective plate 3 will be depressed inwards under pressure, and the cavity 13 and the internal insulation cotton 14 will be used for preliminary pressure resistance and buffering, and then the elastic steel plate 12 will be used for further pressure resistance and buffering, and the second cavity 13 and the internal insulation cotton 14 will be used for pressure resistance and buffering, and finally the elastic steel plate 5 will be used for pressure resistance and buffering. The plate 12 is against, and since the buffer plate 5 is fixed by the support rod 4, the buffer plate 5 can be firmly supported without applying pressure to the trough body 1. The throat section 102 adopts the buffer plate 5 to assist in pressure resistance, while the contraction section 101 and the diffusion section 103 adopt the support frame 2 to assist in pressure resistance, which can effectively improve the anti-freezing and pressure resistance effect of the trough body 1. At the same time, the setting of the thermal insulation cotton 14 and the heating plate 10 can realize the heating of the trough body 1, so that the trough body 1 itself has an anti-freezing and heating effect, which prevents the trough body 1 from deforming itself in cold weather and affecting the water flow measurement accuracy.
