Description

Technical Field

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

[0002] The significance of water conservancy project inspection is mainly reflected in the following aspects: ensuring construction quality and safety, improving project efficiency, guaranteeing safe operation of the project, and promoting technological progress. Water conservancy project inspection devices mainly include the following categories: measuring tools and equipment, metal structure inspection equipment, and underwater structure inspection equipment. Among them, there are devices used to measure various parameters of water conservancy projects, such as elevation difference, azimuth, vertical angle, distance, and water flow velocity. The equipment includes level instruments (such as liquid surface level instruments and optical level instruments), total stations, theodolites, radar level instruments, traverse instruments, triangulation instruments, and water flow velocity measuring instruments. Radar current meters are a type of flow velocity measuring device used in the water conservancy industry. They can realize real-time monitoring and data acquisition of water flow velocity in rivers, providing important support for the management and decision-making of the water conservancy industry. In addition, radar current meters have a non-contact measurement method and are not affected by sewage corrosion and silt, so they are suitable for fields such as water conservancy, hydrology, and environmental pollution monitoring.

[0003] The problems with existing technologies are: 1. In order to comprehensively detect the water flow velocity in water conservancy projects, radar current meters need to be installed at different locations to collect comprehensive data, which increases the complexity of installation. 2. The installation location of radar current meters is fixed, and when the water level rises, the radar current meters are easily submerged, causing damage to the equipment.

[0004] The present invention aims to solve the technical problems existing in the prior art. To this end, a channel flow velocity detection device for water conservancy projects is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a channel flow velocity detection device for water conservancy projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A channel flow velocity detection device for water conservancy projects includes a mounting base with several through holes on its outer surface, an airbag inside the mounting base, a lifting device slidably connected to the mounting base, the lifting device contacting the airbag, and an alarm device on one side of the mounting base that cooperates with the lifting device.

[0008] A drive mechanism is provided on one side of the lifting device, and a detection device is provided on the other side of the lifting device. The detection device is rotatably connected to the drive mechanism.

[0009] As a further embodiment of this utility model: the lifting device includes a push plate, which is slidably connected to the mounting base, contacts the airbag, and cooperates with the alarm device. A lifting rod is fixedly connected to one end of the push plate, a support rod is fixedly connected to one end of the lifting rod, a reinforcing rod is fixedly connected to the cylindrical surface of the lifting rod, the other end of the reinforcing rod is connected to the support rod, and a detection device is fixedly connected to the support rod.

[0010] As a further embodiment of this utility model: the detection device includes a mounting frame, which is fixedly connected to a support rod. A lever is fixedly connected to the support rod, and a swing arm is rotatably connected to the cylindrical surface of the lever. A detector is fixedly connected to the other end of the swing arm. A movable plate is slidably connected to the support rod, and the movable plate has a slot. The lever passes through the slot and slides in contact with the movable plate. A drive mechanism is rotatably connected to the movable plate.

[0011] As a further embodiment of this utility model: the driving mechanism includes a servo motor, which is fixedly connected to a support rod. One end of the servo motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a turntable. The other end of the turntable is rotatably connected to a crank, and the other end of the crank is rotatably connected to a moving plate.

[0012] As a further embodiment of this utility model: the alarm device includes an alarm, which is fixedly connected to the mounting base. One end of the alarm is provided with a point control switch, which cooperates with a push plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the servo motor controls the rotation of the shaft, which drives the turntable to rotate. The turntable drives the moving plate to perform crank-slider motion through the crank. That is, when the turntable rotates, the moving plate is pushed to move left and right back and forth through the crank. The moving plate squeezes the swing arm to make it rotate around the lever as the pivot. The other end of the swing arm drives the detector to swing to increase the detection range, which can reduce the number of detectors installed. When the water level rises, the airbag rises with it. The airbag drives the push plate to rise. The push plate drives the support rod to rise through the lifting rod. The support rod drives the detection device to rise, which can avoid the support rod being submerged in water and thus damaged. At the same time, the device is equipped with an alarm and a point control switch. When the push plate rises to a certain extent, the push plate squeezes the point control switch and the alarm sounds to remind the staff. This device can reduce the number of detectors installed, reduce the complexity of installation, and prevent the support rod from being submerged in water and thus damaged.

[0020] Please see Figure 1-3 A channel flow velocity detection device for water conservancy projects includes a mounting base 1, with several through holes 2 on the outer surface of the mounting base 1, an airbag 12 inside the mounting base 1, a lifting device slidably connected to the mounting base 1, the lifting device contacting the airbag 12, and an alarm device on one side of the mounting base 1, which cooperates with the lifting device.

[0021] A drive mechanism is provided on one side of the lifting device, and a detection device is provided on the other side of the lifting device. The detection device is rotatably connected to the drive mechanism. This device can reduce the number of detectors 8 to be installed, reduce the complexity of installation, and at the same time prevent the support rod 5 from being submerged in water and damaged.

[0022] Please see Figure 1-2The lifting device includes a push plate 11, which is slidably connected to the mounting base 1. The push plate 11 is in contact with the airbag 12 and cooperates with the alarm device. A lifting rod 3 is fixedly connected to one end of the push plate 11, and a support rod 5 is fixedly connected to one end of the lifting rod 3. A reinforcing rod 4 is fixedly connected to the cylindrical surface of the lifting rod 3, and the other end of the reinforcing rod 4 is connected to the support rod 5. A detection device is fixedly connected to the support rod 5. When the water level rises, the airbag 12 rises accordingly, and the airbag 12 drives the push plate 11 to rise. The push plate 11 drives the support rod 5 to rise through the lifting rod 3, and the support rod 5 drives the detection device to rise, thus avoiding damage to the support rod 5 due to water submersion.

[0023] Please see Figure 1-3 The detection device includes a mounting frame 7, which is fixedly connected to a support rod 5. A lever 19 is fixedly connected to the support rod 5. A swing arm 6 is rotatably connected to the cylindrical surface of the lever 19. A detector 8 is fixedly connected to the other end of the swing arm 6. A moving plate 17 is slidably connected to the support rod 5. The moving plate 17 has a slot 18. The lever 19 passes through the slot 18 and slides in contact with the moving plate 17. A drive mechanism is rotatably connected to the moving plate 17. The moving plate 17 presses the swing arm 6 to make it rotate around the lever 19 as the pivot. The other end of the swing arm 6 drives the detector 8 to swing and increase the detection range.

[0024] Please see Figure 3 The driving mechanism includes a servo motor 13, which is fixedly connected to the support rod 5. One end of the servo motor 13 is fixedly connected to a rotating shaft 14, and the other end of the rotating shaft 14 is fixedly connected to a turntable 15. The other end of the turntable 15 is rotatably connected to a crank 16, and the other end of the crank 16 is rotatably connected to a moving plate 17. The servo motor 13 controls the rotating shaft 14 to rotate, and the rotating shaft 14 drives the turntable 15 to rotate. The turntable 15 drives the moving plate 17 to perform crank-slider motion through the crank 16. That is, when the turntable 15 rotates, it pushes the moving plate 17 to perform left and right reciprocating motion through the crank 16.

[0025] Please see Figure 1-2 The alarm device includes an alarm 9, which is fixedly connected to the mounting base 1. One end of the alarm 9 is provided with a point control switch 10. The point control switch 10 cooperates with a push plate 11. When the push plate 11 rises to a certain extent, the push plate 11 presses the point control switch 10, and the alarm 9 sounds an alarm to remind the staff.

[0026] The working principle of this utility model is as follows: When the device is in use, the servo motor 13 controls the rotation of the rotating shaft 14, which in turn drives the turntable 15 to rotate. The turntable 15 drives the moving plate 17 to perform crank-slider motion via the crank 16. That is, when the turntable 15 rotates, it pushes the moving plate 17 to move left and right reciprocally via the crank 16. The moving plate 17 then squeezes the swing arm 6 to make it rotate around the lever 19 as the pivot. The other end of the swing arm 6 drives the detector 8 to swing, increasing the detection range. This reduces the number of detectors 8 that can be installed. When the water level rises, the airbag 12 moves accordingly. As the device rises, the airbag 12 drives the push plate 11 to rise, and the push plate 11 drives the support rod 5 to rise via the lifting rod 3. The support rod 5 then drives the detection device to rise, thus preventing the support rod 5 from being submerged in water and damaged. At the same time, the device is equipped with an alarm 9 and a point control switch 10. When the push plate 11 rises to a certain extent, the push plate 11 presses the point control switch 10, and the alarm 9 sounds to remind the staff. This device can reduce the number of detectors 8 that need to be installed, reduce the complexity of installation, and prevent the support rod 5 from being submerged in water and damaged.
