Technical Field
[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a measuring instrument for water conservancy engineering and water conservancy survey. Background Art
[0002] Water conservancy projects can generally be understood as those that are beneficial to water, or industries that require a large amount of water. Water conservancy surveys are often the first step in water conservancy projects. River hydrological surveys mainly include survey contents such as flow velocity, water level, and flow. Among them, the most important survey indicator is the river flow velocity. Workers generally use flow meters to measure the flow velocity of river water.
[0003] When using existing flow meters to survey water flow, workers generally hold the flow meter display and then put the detection part of the flow meter into the water flow for detection. However, the detection head of the flow meter is easily entangled by debris such as water plants in the river, thereby affecting the detection of the flow meter and causing the water conservancy survey results to be inaccurate.
[0004] Therefore, there is an urgent need for a measuring instrument for water conservancy engineering and water conservancy survey to solve the problem that the detection head of the current meter is easily entangled by water plants and other debris in the river water, affecting the detection accuracy of the current meter.

[0007] The protective mechanism includes a connecting wire, a detection rod, a detection head, a support frame, a fixing ring and a protective net. The back side of the flow meter is electrically connected to the detection rod through the connecting wire. The detection head is installed at the end of the detection rod away from the connecting wire. The support frame is fixedly connected to the outer surface of the detection rod by screws. The fixing ring is welded to the bottom of the support frame, and the protective net is arranged on the outside of the fixing ring.
[0008] The protection of the detection head by the protective net on the outside of the fixed ring makes it difficult for water plants and other debris in the river water to entangle the detection head, so that the flow meter can accurately survey the river flow rate in water conservancy projects.
[0009] Preferably, the protective net is located outside the detection head.
[0010] Preferably, the outer side of the fixing ring is a notch with an arc-shaped structure.

[0012] Preferably, a plurality of groups of small holes are provided at positions corresponding to the bolts on one side of the connecting rod.
[0013] Preferably, the other end of the support rod is welded to the back side of the support rail.
[0014] In summary, the present application includes at least one of the following beneficial effects:
[0015] 1. This measuring instrument is used for water conservancy project survey.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Specifically, the protective mechanism includes a connecting line 111, a detection rod 112, a detection head 113, a support frame 114, a fixing ring 115 and a protective net 116. The back side of the flow meter 4 is electrically connected to the detection rod 112 through the connecting line 111. The detection head 113 is installed at the end of the detection rod 112 away from the connecting line 111. The support frame 114 is fixedly connected to the outer surface of the detection rod 112 by screws. The fixing ring 115 is welded to the bottom of the support frame 114. The protective net 116 is arranged on the outside of the fixing ring 115. The outside of the fixing ring 115 is a notch of an arc structure. The protective net 116 is located on the outside of the detection head 113.
[0025] Through the above technical solution, when the staff puts the detection rod 112 into the river and the detection head 113 detects the flow rate of the river, the protection net 116 on the outside of the fixed ring 115 protects the detection head 113, making it difficult for water plants and other debris in the river to entangle the detection head 113, so that the flow meter 4 can accurately survey the river flow rate in the water conservancy project.
[0026] Specifically, the adjustment mechanism includes a support sleeve 211, a connecting rod 212, a support rod 213 and a bolt 214.
