[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The purpose of the present invention is to provide a wheel water metering device and a measuring method thereof to solve the problems existing in the above-mentioned prior art. The device can be used to measure water flow, and the calculation method is simple and easy to use.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Embodiment 1

[0035] like Figure 1-Figure 5As shown, the present embodiment provides an impeller water metering device, including a water flow box 1 and two impeller bodies 2. The water flow box 1 is a rectangular cylinder structure. The impeller body 2 includes an impeller shaft 201, and the two impeller shafts 201 are transmission-connected to ensure the synchronous rotation of the two impeller bodies 2. A plurality of impeller blades 202 and a plurality of impeller water tanks 203 are provided in the circumferential direction of the impeller shaft 201, and the impeller shaft 201, the impeller blades 202 and the impeller water tanks 203 can form a complete cylindrical structure. The number of impeller blades 202 and the impeller water tanks 203 are the same, the cross-sectional area of ​​the impeller blades 202 and the impeller water tanks 203 are the same, and the impeller blades 202 and the impeller water tanks 203 are staggered, as shown in FIG. Figure 2 As shown. A rectangular impeller installation window is provided on each side of the water-passing box 1, and the impeller shaft 201 is rotatably connected to the impeller installation window. An angle measuring device is installed on one of the impeller shafts 201, and the angle measuring device can be used to measure the rotation angle of the impeller shaft 201.

[0036] In actual use, when water passes through the water box 1, the water flow will drive the two impeller bodies 2 to rotate. During the rotation of the impeller body 2, water will enter the impeller water tank 203 and flow to the downstream of the water flow as the impeller water tank 203 rotates. Since the volume of the water flow tank is equal to (the volume of the impeller body 2-the volume of the impeller shaft 201 in the impeller body 2) / 2, the volume of the water flow tank of the two impeller bodies 2 is the volume of one impeller body 2 minus the volume of the impeller shaft 201 in one impeller body 2. In this way, the water flow obtained by one rotation of the impeller body 2 can be obtained, and then multiplied by the number of rotations of the impeller shaft 201 measured by the angle measuring device, the water flow size within the specified time can be obtained. Further, using (water flow within the specified time / specified time) = flow rate, the flow rate information can be further obtained.

[0037] In this embodiment, if Figure 2 As shown, there are four impeller blades 202 and four impeller water tanks 203. In addition, those skilled in the art can also adjust the specific number of impeller blades 202 and impeller water tanks 203 as needed, generally using a multiple of 4.

[0038] In this embodiment, if Figure 3-Figure 4As shown, the upper end of the impeller shaft 201 and the lower end of the impeller shaft 201 pass through the upper surface of the water box 1 and the lower surface of the water box 1 respectively, and an impeller gear 204 is fixed to the upper end of the impeller shaft 201 and the lower end of the impeller shaft 201 respectively. The corresponding impeller gears 204 on the two impeller bodies 2 are connected through two transmission gears 205, that is, the two impeller gears 204 at the upper ends of the two impeller bodies 2 are meshed through two transmission gears 205, and the two impeller gears 204 at the lower ends of the two impeller bodies 2 are meshed through another two transmission gears 205, so as to realize the synchronous rotation of the two impeller shafts 201. The reason for using two transmission gears 205 to mesh is to ensure that the rotation directions of the two impeller gears 204 are opposite.

[0039] In addition, it should be noted that the impeller gear 204 and the transmission gear 205 are both located on the upper and lower surfaces of the exterior of the water transfer box 1 , rather than inside the water transfer box 1 .

[0040] The upper end of the impeller shaft 201 and the lower end of the impeller shaft 201 are respectively mounted on the upper end of the impeller mounting window and the lower end of the impeller mounting window through bearings, thereby realizing the rotation connection of the impeller shaft 201.

[0041] In this embodiment, a pressure gauge is provided at each end of the water transfer box 1, and the pressure gauge is used to detect the pressure value at the water inlet and outlet of the water transfer box 1. A gate valve is provided at the outlet of the water transfer box 1, and the staff can adjust the water flow rate by adjusting the opening of the gate valve, thereby maintaining the pressure difference between the water inlet and outlet of the water transfer box 1.

[0042] In this embodiment, if Figure 3 and Figure 5 As shown, a protective shell 7 is fixed on both sides of the water box 1. The protective shell is a semi-cylindrical shell, specifically a shell structure formed by dividing a hollow cylindrical structure into two along its diameter. A rectangular sealing connecting plate is correspondingly provided between the upper end and the lower end of the two protective shells 7. The protective shell 7 is located outside the impeller body 2, thereby protecting the impeller body 2 and preventing water from flowing out.

[0043] In this embodiment, the angle measuring device is an existing code disk. Of course, those skilled in the art may also replace it with an angle measuring sensor or other measuring equipment capable of measuring the number of revolutions of the impeller shaft 201 .

[0044] Embodiment 2

[0045] like Figure 1-Figure 7 As shown, this embodiment provides a measurement method of an impeller water measuring device, based on the impeller water measuring device disclosed in the first embodiment, comprising the following steps:

[0046] S1. First, weld a water baffle 3 at both ends of the water box 1. The water baffle 3 is made of PE and is light. The area of ​​the water baffle 3 should be the same as the channel area, specifically in the shape of an inverted trapezoid. The water baffle 3 is provided with a water outlet with the same area as the central channel of the water box 1.

[0047] S2. Put two water retaining plates 3 and the impeller water measuring device (an integrated structure at this time) into the channel together. The water in the channel flows from upstream to downstream. At this time, the upstream side of the upstream water retaining plate 3 is blocked with water and forms a certain pressure. When the water flows through the impeller body 2, under the action of the pressurized water flow, the impeller body 2 rotates rapidly, and the water flows into the impeller water tank 203. At this time, the upper group of impeller blades 202 rotate and block the water. In this time difference, the water at the upstream end of the two impeller bodies 2 rotates to the downstream end, and the water is released to the downstream.

[0048] S3. The number of revolutions of the impeller body 2 is obtained by the angle measuring device within the estimated time, and then the amount of water flowing through is obtained by multiplying the number of revolutions by the volume of the impeller body 2. The volume of the impeller body 2 is (the volume of the cylinder formed by the impeller blades 202, the impeller water tank 203 and the impeller shaft 201) - the volume of the impeller shaft 201 in the impeller body 2. Of course, the volume of the impeller body 2 is a fixed value and can be calculated in advance. In actual use, it is a known quantity and does not need to be calculated again.

[0049] In this embodiment, if Figure 7 As shown, the lower surface of the water baffle 3 is provided with a rubber water stop strip 6. Furthermore, the lower surface and the two side bevels of the water baffle 3 are provided with water stop strips 6. In actual use, the water baffle 3 only needs to be inserted into the groove of the water stop strip 6. Then the water baffle 3 with the water stop strip 6 can be installed in the channel, and the sealing between the water baffle 3 with the water stop strip 6 and the channel will be greatly improved.

[0050] In this embodiment, if Figure 6 As shown, a fixing beam 4 is fixed to the upper end of the water retaining plate 3, and the fixing beam 4 is an I-shaped steel beam. The two ends of the fixing amount are fixed to the concrete blocks 5 on both sides of the channel by screws, so as to realize the fixing of the water retaining plate 3.

[0051] In this embodiment, both sides of the water retaining plate 3 are provided with limiting devices, which can be structures such as limiting protrusions or limiting columns made of concrete, and can be installed in the channel, and the limiting devices on both sides are respectively against the two sides of the water retaining plate 3, which can further improve the fixing effect on the water retaining plate 3. In addition, the limiting devices can also play a guiding role for the water retaining plate 3, and the water retaining plate 3 can be quickly and accurately inserted between the limiting devices on both sides.

[0052] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
