Description

Technical Field

[0001] This utility model relates to the field of water flow velocity detection technology, specifically a flow velocity detection device for water conservancy projects. Background Technology

[0002] In water conservancy projects, it is often necessary to detect and process the flow velocity in a region. After the water enters the flow meter probe, the water will drive the internal worm gear structure to rotate. During the rotation, an electrical signal is generated. The flow velocity can be detected by calculating the electrical signal and data.

[0003] In existing technologies, flow velocity detection devices require frequent relocation, and the amount of water affects the distance between the water surface and the shore. Existing devices cannot be flexibly adjusted to meet different needs. Utility Model Content

[0004] The purpose of this invention is to provide a flow velocity detection device for water conservancy projects, so as to solve the problem that existing devices in the above-mentioned background art cannot be flexibly adjusted to adapt to different needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flow velocity detection device for water conservancy projects, including a support column, a flip adjustment component is provided on the outside of the support column, and the flip adjustment component is used to flexibly adjust to adapt to the position of the detected water flow and the positioning area, and a splicing adjustment component is provided on the right side of the upper end of the flip adjustment component, and the splicing adjustment component is used to flexibly splice to adapt to different needs.

[0006] The flip adjustment assembly includes a horizontal support, which is located on the left side of the support column. Guide wheels are provided on the inner side of the end of the horizontal support and the inner side of the upper end of the support column. A flip sleeve is provided on the right side of the upper end of the support column. The flip adjustment assembly includes a winch, which is located below the horizontal support. A pull rope is provided at the output end of the winch, and a welding block is installed at the end of the pull rope. The welding block is located at the top of the flip sleeve.

[0007] The splicing adjustment assembly includes a telescopic rod, which is located inside the flip sleeve. A limit bracket is installed at the right end of the telescopic rod, and a flip column is movably arranged inside the limit bracket. Several sets of splicing rods are arranged inside the flip column. A threaded groove is opened at the top of each set of splicing rods, and a threaded rod is installed at the bottom of each set of splicing rods. The threaded rod is correspondingly arranged inside the threaded groove.

[0008] Preferably, the left end of the flip sleeve is provided with a limiting plate on the front and back, and the limiting plate is located on the front and back of the upper end of the support column, and the right end of the flip sleeve is provided with a fastening knob on the front.

[0009] Preferably, a drive motor is mounted on the front of the winch, and the shaft head at the output end of the drive motor is fixed to one end of the pull rope.

[0010] Preferably, a controller is installed on the front right side of the winch, and a connecting wire is provided on the right side of the controller. A sensor is installed at the end of the connecting wire, and a flow meter probe is installed at the bottom of the sensor.

[0011] Preferably, a fixing column is installed at the bottom of the supporting column, and a bearing sleeve is provided on the outer side of the lower end of the fixing column.

[0012] Preferably, a fixing plate is installed at the bottom of the bearing sleeve, and positioning rods are installed at the bottom of the four corners of the fixing plate.

[0013] Preferably, a locking knob is provided on the right side of the flip column, and the end of the locking knob presses against the splicing rod on the inner side.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model, by installing a flip-adjustment component, provides an installation position for the overall structure at the top using a support column. The pull rope is guided to connect with the winch and welding block by cooperating with the guide wheel on the horizontal bracket and the support column. The winch can directly control and adjust the length of the pull rope, which in turn drives the flip sleeve to flip along the limit plate. The adjustment can be made according to the water level, making it easy to submerge the sensor structure in the water. In the non-use state, the flip sleeve can be kept facing downwards, thus achieving a folding effect. Compared with existing detection devices, this effectively reduces the space occupied and makes it convenient for staff to carry and use.

[0016] Secondly, this utility model, by installing a splicing adjustment component, allows for angle adjustment of the flip sleeve after the flip adjustment component is set. The rigidly connected sensor probe structure at the bottom cannot guarantee verticality to the water surface, and the height of the flow meter probe cannot be flexibly controlled. By setting a telescopic rod, the position of the end structure can be adjusted, and the limiting bracket can provide restriction for the flip column, assisting in the flip adjustment angle. This angle has a certain range limitation, but it can ensure to a certain extent that the splicing rod can be perpendicular to the water surface, ensuring that the flow meter probe can penetrate into the water flow more quickly for detection. It is convenient to adjust and use according to needs, and the length of the splicing rod can be increased according to the depth. Attached Figure Description

[0027] Through the above technical solution, the position of the end structure can be adjusted by setting the telescopic rod 401, and the limiting bracket 402 can provide a restriction for the flipping column 403 to assist in the flipping adjustment angle. This angle has a certain range limitation, but it can ensure that the splicing rod 4 can be perpendicular to the water surface to a certain extent, so that the flow meter probe 206 can penetrate into the water flow more quickly for detection. It is convenient to adjust and use according to needs, and the length of the splicing rod 4 can be increased according to the depth.

[0028] Specifically, the left end of the flip sleeve 104 is provided with a limiting plate 103 on the front and back, and the limiting plate 103 is located on the front and back of the upper end of the support column 1. The right end of the flip sleeve 104 is provided with a fastening knob 106 on the front.

[0034] Specifically, a fixing column 301 is installed at the bottom of the supporting column 1, and a bearing sleeve 302 is provided on the outer side of the lower end of the fixing column 301.

[0035] Through the above technical solution, the fixed column 301 can be connected to the bearing sleeve 302, which can help support the column 1 to rotate and adjust its orientation.

[0036] Specifically, a fixing plate 303 is installed at the bottom of the bearing sleeve 302, and positioning pins 3 are installed at the bottom of the four corners of the fixing plate 303.

[0038] Specifically, a locking knob 404 is provided on the right side of the flip column 403, and the end of the locking knob 404 presses against the splicing rod 4 on the inner side.

[0039] Through the above technical solution, the locking knob 404 can restrict the movable splicing rod 4, making it convenient to adjust the height.

[0040] In use, first insert the positioning rod 3 directly into the ground, then adjust the length of the telescopic rod 401 according to the distance and depth of the water surface and lock it with the fastening knob 106. Then connect multiple sets of splicing rods 4, adjust the height and limit it with the locking knob 404. Then control the pull rope 2 to retract through the winch 201. After retraction, the flip sleeve 104 can be controlled to flip and adjust the angle along the limit plate 103. During the adjustment process, the splicing rod 4 will always remain vertical and move along the limit bracket 402. After the flow meter probe 206 is submerged in the water, the water flow velocity can be detected by the sensor 205.
