Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to a mounting base for a portable water flow meter. Background Technology

[0002] A water flow meter (also known as a flow velocity meter or flow velocity measuring instrument) is an instrument used to measure the velocity of water flow. It is widely used in water conservancy projects, river monitoring, environmental protection and other fields to assess the flow of water.

[0003] There are many existing hydraulic flow velocity meters. For example, patent CN222420247U discloses a flow velocity detection device for hydraulic engineering. This device solves the problem of the need to install radar flow velocity meters at different locations to collect comprehensive data in order to comprehensively detect the water flow velocity in hydraulic engineering. However, when using the flow velocity meter in places such as turbid water, it is inconvenient to adjust the placement of the flow velocity meter. When detecting water flow, the flow velocity meter needs to be placed in the middle layer of the water flow, where the flow velocity is usually more uniform and the flow velocity changes less. However, in turbid water, it is inconvenient for personnel to observe the placement of the flow velocity meter. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a portable hydraulic flow meter mounting base, which effectively solves the problem that turbid water makes it inconvenient for personnel to observe the placement of the flow meter.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a portable hydraulic current meter mounting base, including:

[0007] Mounting plate, with a main rod located below the mounting plate;

[0008] A guide assembly, comprising side rods symmetrically arranged on the outer wall of the main rod, wherein a guide plate is fixedly installed at the lower end of the side rods;

[0009] The adjustment assembly includes a floating cover slidably disposed on the outer wall of the main rod, a foam block fixedly installed on the upper end surface of the floating cover, a flow meter body disposed below the floating cover, and a telescopic tube fixedly installed on the upper end surface of the flow meter body.

[0010] Preferably, a connecting rod is rotatably mounted on the lower end face of the mounting plate, the lower end face of the connecting rod is rotatably connected to the main rod, and a chassis is rotatably mounted on the lower end of the main rod.

[0011] Preferably, a fixed plate is fixedly installed on the outer wall of the connecting rod, a rotating plate is rotatably installed on the lower end face of the fixed plate, and rotating heads are symmetrically installed on the outer wall of the main rod, with the inner wall of the rotating head rotatably connected to the side rod.

[0012] Preferably, a connecting seat is fixedly installed on the upper end face of the side rod, and a spring is fixedly installed between the connecting seat and the rotating disk.

[0013] Preferably, the main rod has an inner groove, and a slider is slidably installed on the inner wall of the inner groove. The two ends of the slider are fixedly connected to the floating cover. The lower end face of the slider is fixedly connected to the telescopic tube. A corrugated telescopic tube is fixedly installed on the upper end face of the slider. A connector is fixedly installed on the upper end face of the corrugated telescopic tube. The connector is fixedly connected to the inner top of the inner groove.

[0014] Preferably, the outer wall of the connector is symmetrically connected with an air supply pipe, and the lower end of the air supply pipe is connected to a telescopic pipe.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. By setting up a coordinated structure of guiding and adjusting components, the problem of difficult positioning of the flow meter in turbid water flow environment is effectively solved. The double-sided guiding structure composed of the guide plate and the side rod can automatically adjust the direction of the main rod with the impact of the water flow, ensuring that the flow meter is always facing the direction of the water flow. At the same time, the floating system composed of the floating cover and foam blocks uses buoyancy to drive the slider linkage mechanism, so that the flow meter body automatically sinks to the middle layer of the water flow. This mechanical adaptive design not only avoids the tedious operation of repeated manual adjustment, but also ensures that representative flow velocity data can still be accurately obtained when visual observation is not possible in turbid water.

[0017] 2. By adopting a pneumatic linkage device consisting of a corrugated telescopic tube and an air supply pipe, passive automatic compensation for the sinking depth of the current meter is achieved. When the floating cover rises and falls with the water level, the slider drives the corrugated telescopic tube to compress or expand. The air pressure change is transmitted to the telescopic tube through the air supply pipe, driving the current meter body to maintain a constant depth in the water flow. This structure can complete the depth adjustment without an external power source, and is particularly suitable for complex water environments in the field, significantly improving the adaptability of the equipment under different hydrological conditions and the stability of the measurement data.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 5 Portable hydraulic current meter mounting base, including:

[0028] Mounting plate 1, with a main rod 102 installed below it;

[0029] Guide assembly 2 includes side rods 204 symmetrically arranged on the outer wall of the main rod 102, and a guide plate 205 is fixedly installed at the lower end of the side rods 204;

[0030] Adjustment component 3 includes a float cover 306 slidably disposed on the outer wall of the main rod 102. A foam block 307 is fixedly installed on the upper end surface of the float cover 306. The foam block 307 and the float cover 306 can always be kept above the water flow, driving the flow meter body 309 to move to the middle layer of the water flow. The flow meter body 309 is disposed below the float cover 306, and a telescopic tube 308 is fixedly installed on the upper end surface of the flow meter body 309.

[0031] Reference Figure 2 A connecting rod 101 is rotatably mounted on the lower end face of the mounting plate 1. The lower end face of the connecting rod 101 is rotatably connected to the main rod 102. A base plate 103 is rotatably mounted on the lower end of the main rod 102. The base plate 103 is used to contact the bottom of the water.

[0032] Reference Figure 3 A fixed plate 201 is fixedly installed on the outer wall of the connecting rod 101. A rotating plate 202 is rotatably installed on the lower end face of the fixed plate 201. A rotating head 203 is symmetrically installed on the outer wall of the main rod 102. The inner wall of the rotating head 203 is rotatably connected to the side rod 204. A connecting seat 206 is fixedly installed on the upper end face of the side rod 204. A spring 207 is fixedly installed between the connecting seat 206 and the rotating plate 202. The elastic force of the spring 207 can keep the side rod 204 and the guide plate 205 in a downward direction.

[0033] Reference Figures 4 to 5 The main rod 102 has an inner groove 301 inside. A slider 305 is slidably installed on the inner wall of the inner groove 301. The two ends of the slider 305 are fixedly connected to the floating cover 306. The lower end face of the slider 305 is fixedly connected to the telescopic tube 308. The telescopic tube 308 is composed of two hollow tubes with mutually limiting inner and outer walls and airtight sliding connection. Air is transported into it through the air supply pipe 304 to increase the air pressure and make them slide against each other. A corrugated telescopic tube 302 is fixedly installed on the upper end face of the slider 305. A connector 303 is fixedly installed on the upper end face of the corrugated telescopic tube 302. The connector 303 is fixedly connected to the inner top of the inner groove 301. The outer wall of the connector 303 is symmetrically connected to the air supply pipe 304. The lower end of the air supply pipe 304 is connected to the telescopic tube 308.

[0034] The working principle of this utility model is as follows:

[0035] By installing the mounting plate 1 above the water flow, the main rod 102 and the base 103 are placed inside the water flow. The side rod 204 and the guide plate 205 are also placed inside the water flow. When the water is flowing, the water flow will cause the guide plate 205 to swing. The two guide plates 205 automatically drive the side rod 204, the rotating head 203 and the main rod 102 to rotate in the state of water flow, and adjust along the direction of water flow, so as to ensure that the flow meter body 309 is set along the direction of water flow.

[0036] It should be noted that when the guide plate 205 is not placed in the direction of water flow, the impact force of the water flow will push the guide plate 205, side rod 204, rotating head 203 and main rod 102 to rotate. The two guide plates 205 will swing automatically with the impact of the water flow. The rotating disk 202 is in a rotating state with the fixed disk 201 during the swing. The elastic force of the spring 207 will continuously push the connecting seat 206, so that the side rod 204 and guide plate 205 are always in a downward device and inside the water flow.

[0037] After contact with the water flow, the buoyancy of the foam block 307 will cause the float cover 306 and the slider 305 to move upward. The slider 305 will drive the telescopic tube 308 to move upward together. During the upward movement, the slider 305 will compress the air inside the corrugated telescopic tube 302, causing the air inside the corrugated telescopic tube 302 to flow into the telescopic tube 308 through the connector 303 and the air supply pipe 304. This increases the air pressure inside the telescopic tube 308 and automatically pushes the flow meter body 309 down to the middle layer of the water flow. The flow in the middle layer of the water flow is usually more uniform and the flow velocity changes less, which helps the flow meter body 309 to obtain representative flow velocity data.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
