Description

Technical Field

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

[0002] Hydraulic engineering testing refers to the activities of inspecting, measuring, testing, or quantifying the physical structure of a hydraulic engineering project, as well as the raw materials, intermediate products, metal structures, and electromechanical equipment used in the project, in accordance with relevant national laws, regulations, and standards, and comparing the results with relevant standards and requirements to determine whether the project quality is up to standard. During hydraulic engineering testing, it is necessary to detect the flow velocity at the drainage outlet, thus requiring the use of flow velocity testing equipment.

[0003] A flow velocity detection device for drainage outlets, disclosed in CN214794863U, for water conservancy testing, includes: a drainage pipe outlet with a flow velocity detection channel bolted to its right side, and a flow velocity display panel mounted above the flow velocity detection channel; a filter baffle bolted to the inner wall of the drainage pipe outlet, with mounting plates symmetrically mounted on the right side of the filter baffle, and an active rotating rod rotatably connected to the mounting plate via bearings; a fan blade mounted on the outside of the active rotating rod; and a fixing seat mounted in the middle of the right side of the filter baffle. This flow velocity detection device for drainage outlets, with its mesh-like filter baffle, can contain large-volume debris in the water flow, preventing it from adhering and accumulating inside the flow velocity detection device, thus avoiding damage to internal parts and reducing the need for disassembly and cleaning, thereby improving the ease of use of the device.

[0004] The existing technology has the following shortcomings: During use, the depth of the detection probe in the water flow at the drain outlet cannot be easily adjusted, which makes the detection results of the drain outlet flow velocity prone to deviation and affects the accuracy of the drain outlet flow velocity detection results. Utility Model Content

[0005] The purpose of this invention is to provide a drainage outlet flow velocity detection device for water conservancy testing. By moving two movable seats relative to or away from each other, the height of the support plate can be adjusted under the traction of the traction plate, and the height of the detection probe inside the fixed sleeve can be adjusted. The fixing nut can fix the adjusted connecting sleeve, so that the detection probe can stably detect the flow velocity of the drainage outlet, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage outlet flow velocity detection device for water conservancy monitoring, comprising a device body, and further comprising:

[0007] The detection mechanism, located on the inner wall of the top of the equipment body, is used to detect the flow rate at the drain outlet;

[0008] The detection mechanism includes two traction springs, which are respectively disposed on the inner walls of the top two ends of the equipment body. A movable seat is fixedly installed on the opposite ends of the two traction springs. A traction plate is rotatably installed on the top of the two movable seats.

A flow rate display instrument is fixedly installed on the top of the connecting sleeve. A detection probe is fixedly installed on the bottom of the connecting sleeve. A fixing nut is provided between the connecting sleeve and the inner wall of the top of the equipment body.

[0009] Preferably, the device body includes a fixed sleeve, and a plurality of connecting bolts are threaded at equal intervals on the inner wall of one end of the fixed sleeve. The ends of the plurality of connecting bolts away from the fixed sleeve are threadedly connected to the inner wall of the drain outlet. A filter plate is fixedly installed on the inner wall of the end of the fixed sleeve near the drain outlet.

[0010] Preferably, the inner walls at both ends of the top of the fixed sleeve are provided with movable grooves, and the two movable grooves are respectively fixedly connected to two traction springs at their adjacent inner walls.

[0011] Preferably, a limiting rod is fixedly installed on the inner wall of each of the two movable slots, the outer wall of each limiting rod is movably connected to the inner wall of each of the two movable seats, and the two limiting rods are movably inserted into the inner side of adjacent traction springs.

[0012] Preferably, each of the two traction plates is rotatably mounted with a fixed seat on its top, and the top of each of the two fixed seats is fixedly connected to the bottom ends of the support plate, respectively.

[0013] Preferably, a fixing groove is provided on the top inner wall of the fixing sleeve at a position between the two movable grooves, the inner wall of the fixing groove is threaded to the outer wall of the fixing nut, and the inner wall of the fixing nut is threaded to the outer wall of the connecting sleeve.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The connecting sleeve moves along the fixed groove, and under the action of the support plate, it can push the two traction plates to move, thereby causing the two movable seats to move relative to each other or away from each other, and causing the two traction springs to extend or retract. Then, the connecting sleeve and the fixed groove are connected by a fixing nut to keep the adjusted connecting sleeve stable, so that the depth of the detection probe inside the fixed sleeve can be easily measured, and the flow velocity at different depths of the drain outlet can be easily detected, which can improve the accuracy of the flow velocity detection results.

[0016] 2. The movement of the movable seat can be limited by the movable groove and the limiting rod, so that the movable seat remains stable during movement, the support plate remains stable during height adjustment, and the connecting sleeve remains stable during height adjustment, so that the detection probe can stably detect the flow rate of the drain outlet.

[0026] This utility model provides, for example Figure 1 The drainage outlet flow velocity detection device shown includes the device body 1, and also includes:

[0027] The detection mechanism 2 is located on the inner wall of the top of the equipment body 1 and is used to detect the flow rate of the drain outlet.

[0028] To facilitate the detection of flow velocity at different depths of the drain outlet, such as Figures 1-3 and Figure 5 As shown, the detection mechanism 2 includes two traction springs 201, which are respectively set on the inner walls of the top two ends of the equipment body 1. Movable seats 202 are fixedly installed on the opposite ends of the two traction springs 201. Traction plates 204 are rotatably installed on the top of the two movable seats 202. Support plates 206 are set on the top of the two traction plates 204. Connecting sleeves 207 are fixedly installed on the inner wall of the support plates 206. Flow rate display instruments 208 are fixedly installed on the top of the connecting sleeves 207. Detection probes 209 are fixedly installed on the bottom of the connecting sleeves 207. Fixing nuts 210 are set between the connecting sleeves 207 and the inner wall of the top of the equipment body 1. The connecting sleeves 207 move along the inner wall of the fixing groove 105, and under the traction of the traction plates 204, they can push the two movable seats 202 to move relative to or away from each other. Then, the fixing nuts 210 can be used to fix the adjusted connecting sleeves 207.

[0029] In order to enable the device body 1 to stably detect the flow velocity at the drain outlet, such as Figures 1-2 and Figure 4 As shown, the device body 1 includes a fixed sleeve 101. Multiple connecting bolts 102 are threaded at equal intervals on the inner wall of one end of the fixed sleeve 101. The ends of the multiple connecting bolts 102 away from the fixed sleeve 101 are threaded to the inner wall of the drain outlet. A filter plate 103 is fixedly installed on the inner wall of the end of the fixed sleeve 101 near the drain outlet. The connecting bolts 102 penetrate the inner wall of one end of the fixed sleeve 101 and are threaded to the inner wall of the drain outlet, so that the device body 1 can be stably connected to the drain outlet.

[0030] To ensure the stability of the connecting sleeve 207 during height adjustment, such as Figures 2-5 As shown, the inner walls of both ends of the top of the fixed sleeve 101 are provided with movable grooves 104. The ends of the inner walls of the two movable grooves 104 that are close to each other are fixedly connected to the two traction springs 201. The inner walls of the two movable grooves 104 are fixedly installed with limiting rods 203. The outer walls of the two limiting rods 203 are movably connected to the inner walls of the two movable seats 202. The two limiting rods 203 are movably inserted into the inner side of the adjacent traction springs 201. The tops of the two traction plates 204 are rotatably installed with fixed seats 205. The tops of the two fixed seats 205 are fixedly connected to the bottom ends of the support plate 206. The movable grooves 104 and the limiting rods 203 can limit the movement of the movable seats 202, thereby making the connecting sleeve 207 stable during height adjustment.

[0031] To facilitate the fixing of the adjusted connecting sleeve 207, such as Figures 2-5As shown, a fixing groove 105 is provided on the top inner wall of the fixing sleeve 101 at a position between the two movable grooves 104. The inner wall of the fixing groove 105 is threaded to the outer wall of the fixing nut 210. The inner wall of the fixing nut 210 is threaded to the outer wall of the connecting sleeve 207. The fixing nut 210 moves downward along the thread of the outer wall of the connecting sleeve 207 and then is threaded to the inner wall of the fixing groove 105, which can fix the adjusted connecting sleeve 207.

[0032] When detecting the flow velocity at the drain outlet, the device body 1 is installed at the drain outlet. Then, the connecting bolt 102 is used to penetrate the inner wall of the fixing sleeve 101 and threadedly connected to the inner wall of the drain outlet, so that the device body 1 is tightly connected to the drain outlet. The water flowing from the drain outlet can then be filtered by the filter plate 103. By pushing the support plate 206 up and down, the connecting sleeve 207 can be moved up and down, allowing adjustment of the height of the detection probe 209 inside the fixing sleeve 101. At the same time, the movement of the support plate 206 can move the two traction plates 204, which in turn can move the two movable seats 202 outside the limiting rod 203. The two traction springs 201 extend or retract as the two moving grooves 104 move relative to or opposite to each other along their inner walls. Then, the fixing nut 210 moves along the threaded outer wall of the connecting sleeve 207 so that it can be threaded into the fixing groove 105. The fixing nut 210 can fix the adjusted connecting sleeve 207, thereby facilitating the detection of the water flow velocity at different depths of the detection probe 209 at the drain outlet. This improves the accuracy of the flow velocity detection results. This embodiment specifically solves the problem in the prior art that it is not convenient to detect the flow velocity at different depths of the drain outlet, which affects the accuracy of the detection results.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
