Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy monitoring devices, and in particular to a water conservancy monitoring device for a digital water conservancy project of the Internet of Things. Background Art

[0002] When conducting hydraulic monitoring on water conservancy projects, it is often necessary to measure the flow rate of the water level in the dam. However, when measuring the water level, it is currently necessary to measure the water flow in the low water level part, and the flow rate of the water flow in the low water level is different from the flow rate in the high water level.

[0003] In view of the above problems, the invention patent with the publication number of "CN118225183A" discloses a water conservancy monitoring device for water conservancy projects, including a connecting frame, movable grooves are provided on both sides of the connecting frame, and the inner wall of the movable groove is fixedly connected with a connecting rod. It mainly designs a cleaning component, a pressure measuring mechanism and a flow rate mechanism to prevent the water flow at the bottom of the water level from clamping the water grass and attaching to the surface of the monitoring device to affect it, and observes the impact force of the water flow while measuring the water level flow rate. However, in this scheme, the main way to clean the water grass is to clamp and push the water grass to the area set in the device. After long-term treatment, this treatment method will also cause excessive accumulation of water grass in the device, which is difficult to deal with later; and this scheme adopts the method of air pressure flow to achieve the technical effect of impact force observation. This technical scheme has high requirements on the air tightness of the pipeline in the device. Once the pipeline has problems such as insufficient sealing and gas leakage, the impact force detection function and automatic alarm function of the monitoring device will be directly paralyzed, and it is difficult to continue normal monitoring work. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a water conservancy monitoring device for digital water conservancy projects of the Internet of Things.

[0006] Preferably, the first transmission mechanism comprises a pair of racks, one end of the pair of racks is fixed on the side wall of the sliding block, and the other end passes through the outside of the device seat, and the pair of racks are respectively meshed with a pair of incomplete gears.

[0007] Preferably, the aquatic plant cleaning assembly consists of a pair of pads, incomplete gears, bent arms, arc-shaped cleaning plates and a plurality of rake teeth, the pair of pads being fixed on both sides of the device seat, the pair of incomplete gears being rotatably connected to the upper ends of the pair of pads respectively, one ends of the pair of bent arms being fixedly connected to the incomplete gears through torque springs, the arc-shaped cleaning plate being fixed to the other end of the bent arms, and the plurality of rake teeth being arranged on the inner arc side wall of the arc-shaped cleaning plate.

[0008] Preferably, a pair of the observation panels are fixed on both sides of the upper end of the device base, and the plurality of height sensors are vertically arranged on the side walls of the observation panels. The touch alarm is fixed on the top of the observation panels, and a slide groove is provided on the side wall of the observation panels, and the observation block is slidably arranged inside the slide groove.

[0009] Preferably, the second transmission mechanism includes a gear, a threaded rod and a sleeve, the threaded rod is rotatably connected to the upper end of the pad, the gear is fixedly sleeved on the lower end of the threaded rod and meshes with the incomplete gear, and the sleeve is threadably sleeved on the threaded rod and fixedly connected to the observation block through a connecting rod.

[0010] Preferably, a pump box is fixedly provided in the middle of the upper end of the device seat, a pair of jet boxes are symmetrically fixedly provided on both sides of the upper end of the device seat, the jet boxes are each provided with an inclined jet tube, and a pump mechanism for pumping fluid into the jet box is installed in the pump box.

[0011] Preferably, the pump flow mechanism includes a pair of pistons sealingly and slidably connected between the inner walls of the pump flow box, an inlet pipe connecting the end of the pump flow box and the air above the water body, and an outlet pipe connecting the end of the pump flow box and the jet box. A driving mechanism for driving the piston to reciprocate is installed in the pump flow box.

[0012] Preferably, the driving mechanism includes a cup wheel rotatably connected to the pump flow box, a cam rotatably connected inside the pump flow box, and a return spring elastically connected to the piston and the inner wall of the pump flow box, the cup wheel and the cam are fixedly connected by a rotating shaft, and the return spring is used to push the piston to reset.

[0013] Preferably, a one-way valve is installed in the inlet pipe to allow air to flow from outside the water body to the pump flow box, and a one-way valve is installed in the outlet pipe to allow air to flow from the pump flow box to the jet box, so as to control the air flow state in the corresponding pipeline.

[0014] Preferably, the cup wheel comprises an intermediate column and a plurality of cup-shaped wheel assemblies, and the plurality of wheel assemblies are arranged in a ring shape on the side wall of the intermediate column through wheel rods, and are used to convert the kinetic energy of water flow impact into mechanical energy of shaft rotation.

[0015] The present invention has the following beneficial effects: 1. By setting up a waterweed cleaning component, when the water flow hits the baffle ring, the sliding block slides to both sides through the transmission action of the rotating rod, so that the rack intermittently engages with the incomplete gear. In this process, under the action of the torque spring, the bending arm drives the arc-shaped cleaning plate to swing back and forth, so that the waterweed debris in the water body in front of the device seat is pushed to both sides for cleaning, which can not only achieve the effect of cleaning waterweed debris in the prior art solution mentioned in the background technology, but also avoid the problem of waterweed accumulation after long-term action, which makes the cleaning work unable to continue; 2. By setting up an impact observation component, when the water flow impacts the baffle ring, the sliding block slides to both sides, so that the rack intermittently meshes with the incomplete gear, the incomplete gear meshes with the gear, and the gear intermittently rotates unidirectionally, so that the threaded rod produces intermittent unidirectional rotation, and the threaded sleeve and the observation block produce an upward movement. At this time, the height sensor set on the observation stand will sense the position of the observation block, and use this as a basis to determine the magnitude of the water flow impact force at this time. When the water flow impact force exceeds the warning value, the sliding block completely slides to the side of the slot. At this time, the observation block will rise to the top of the slide and contact the touch alarm, causing it to start an alarm and remind the staff in the dam. This observation component does not use an air path structure and has no pipeline sealing requirements, which avoids the problem that once the pipeline is insufficiently sealed or gas leaks, the impact force detection function and the automatic alarm function of the monitoring device will be directly paralyzed, making it difficult to continue normal monitoring work. 3. By setting up mechanisms such as a pump flow mechanism, a driving mechanism and a jet box, when water flows through the device seat, the impact of the water body will cause the cup wheel to rotate continuously, and the cup wheel drives the cam to rotate, thereby cooperating with the reset spring to make the two pistons reciprocate horizontally, and then pump the air into the jet box through the inlet pipe and the outlet pipe, and spray it out from each jet tube, generating a certain airflow impulse, thereby flushing away the aquatic plants, debris and mud in the water body at the opening of the jet tube, preventing these water substances from being wrapped into the first transmission mechanism and the second transmission mechanism, ensuring the normal operation of the first transmission mechanism and the second transmission mechanism, and then ensuring the normal operation of the entire monitoring device.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1

[0020] Reference Figure 1-3, a water conservancy monitoring device for an Internet of Things digital water conservancy project, comprising a device seat 1 provided with a counterweight base 2 and a notch 3, a flow rate measurement component, an impulse observation component and a waterweed cleaning component: The flow rate measuring assembly is composed of a baffle ring 6, a tension sensor 7 and a pair of sliding blocks 4, and is used to measure the current water level and water flow rate. The pair of sliding blocks 4 slide symmetrically in the slot 3. The baffle ring 6 is semi-annular and is movably connected to the pair of sliding blocks 4 through a pair of rotating rods 5. The pair of sliding blocks 4 are connected to the tension sensor 7 through a pair of tension springs 8. The impact force observation component is composed of an observation stand 19, a height sensor 21, a touch alarm 22 and an observation block 18, and is used to observe the impact force of the current water level. A pair of observation stands 19 are fixed on both sides of the upper end of the device seat 1, and multiple height sensors 21 are vertically arranged on the side walls of the observation stand 19. The touch alarm 22 is fixed on the top of the observation stand 19. A slide groove 20 is opened on the side wall of the observation stand 19, and the observation block 18 is slidably arranged inside the slide groove 20. like Figure 3 As shown, the waterweed cleaning assembly consists of a pair of pads 23, an incomplete gear 10, a bending arm 11, an arc-shaped cleaning plate 12 and a plurality of rake teeth 13, and is used to clean waterweed debris mixed in the water body in front of the device. The pair of pads 23 are fixed on both sides of the device seat 1, and the pair of incomplete gears 10 are rotatably connected to the upper ends of the pair of pads 23 respectively. One end of the pair of bending arms 11 is fixedly connected to the incomplete gear 10 through a torque spring, and the arc-shaped cleaning plate 12 is fixed to the other end of the bending arm 11. The plurality of rake teeth 13 are arranged on the inner arc side wall of the arc-shaped cleaning plate 12; like Figure 2 As shown, the water grass cleaning component is connected to the flow rate measuring component through a first transmission mechanism, and the first transmission mechanism includes a rack 9, one end of a pair of racks 9 is fixed on the side wall of the sliding block 4, and the other end passes through the outside of the device seat 1, and the pair of racks 9 are respectively engaged with a pair of incomplete gears 10.

[0021] The impact observation assembly is connected to the waterweed cleaning assembly through a second transmission mechanism, which includes a gear 14, a threaded rod 15 and a sleeve 16. The threaded rod 15 is rotatably connected to the upper end of the pad 23, the gear 14 is fixedly sleeved on the lower end of the threaded rod 15 and meshes with the incomplete gear 11, and the sleeve 16 is threadedly sleeved on the threaded rod 15 and fixedly connected to the observation block 18 through a connecting rod 17.

[0022] It should be added that the tension sensor 7, height sensor 21 and touch alarm 22 included in the above content are all based on the Internet of Things digital technology to connect to big data and the Internet. The measured data can be uploaded to the Internet port in real time. The dam staff can view the data observed by these three instruments in real time through the Internet, which is convenient for them to manage the dam and related water conservancy work. This is an existing mature technology and will not be elaborated here.

[0023] In this embodiment, when in use, the monitoring device is first placed inside the water body. The setting of the counterweight base 2 can ensure the stability of the device base 1 in the water body. When the water flows through the monitoring device, the water body will impact the baffle ring 6. The baffle ring 6 moves backward under the impact and pushes a pair of sliding blocks 4 to slide to both sides through the rotating rod 5. The sliding of the sliding block 4 will generate a pulling force on the tension sensor 7 through the tension spring 8. The tension sensor 7 measures the tension data and uploads it to the Internet port, which is recorded by the staff and converted into flow rate data.

[0024] While the water flow impacts the baffle ring 6, the sliding block 4 slides to both sides through the transmission action of the rotating rod, so that the rack 9 intermittently engages with the incomplete gear 10. In this process, under the action of the torque spring, the bending arm 11 drives the arc-shaped cleaning plate 12 to swing back and forth, thereby clearing the aquatic plants and debris in the water body in front of the device seat 1 to both sides. It can not only achieve the effect of cleaning aquatic plants and debris in the prior art solution mentioned in the background technology, but also avoid the problem of aquatic plants accumulation after long-term action, which makes the cleaning work unable to continue.

[0025] At the same time, the incomplete gear 10 meshes with the gear 14, and the gear 14 rotates intermittently in one direction, so that the threaded rod 15 produces intermittent unidirectional rotation, and the threaded sleeve 15 and the observation block 18 produce an upward movement. At this time, the height sensor 21 arranged on the observation stand 19 will sense the height position of the observation block 18 and upload the data to the Internet port. The staff uses this as a basis to determine the size of the water flow impact force at this time. When the water flow impact force exceeds the warning value, the sliding block 4 slides completely to the side of the slot 3. At this time, the observation block 18 will rise to the top of the slide 20 and contact the touch alarm 22, causing it to start an alarm to remind the staff in the dam. This observation component does not adopt an air path structure and has no pipeline sealing requirements, avoiding the problem that once the pipeline is insufficiently sealed or gas leaks, the impact force detection function and the automatic alarm function of the monitoring device will be directly paralyzed, making it difficult to continue normal monitoring work.

The jet boxes 26 are each provided with an inclined jet tube 27, and a pump mechanism for pumping fluid into the jet box 26 is installed in the pump box 24.

[0028] The pump flow mechanism includes a pair of pistons 31 sealed and slidably connected between the inner walls of the pump flow box 24, an inlet pipe 28 connected between the end of the pump flow box 24 and the air above the water body, and an outlet pipe 29 connected between the end of the pump flow box 24 and the jet box 26. A driving mechanism for driving the piston 31 to reciprocate is installed in the pump flow box 24.

[0029] A one-way valve is installed in the inlet pipe 28 to allow air to flow from outside the water body to the pump flow box 24, and a one-way valve is installed in the outlet pipe 29 to allow air to flow from the pump flow box 24 to the jet box 26, so as to control the air flow state in the corresponding pipeline.

[0030] The driving mechanism includes a cup wheel 25 rotatably connected to the pump flow box 24, a cam 30 rotatably connected inside the pump flow box 24, and a return spring 32 elastically connected to the piston 31 and the inner wall of the pump flow box 24. The cup wheel 25 and the cam 30 are fixedly connected by a rotating shaft, and the return spring 32 is used to push the piston 31 to return to its original position.

[0031] The cup wheel 25 includes a middle column and a plurality of cup-shaped wheel assemblies. The plurality of wheel assemblies are arranged in a ring shape on the side wall of the middle column through wheel rods, and are used to convert the kinetic energy of water flow impact into mechanical energy for the rotation of the shaft.

[0032] In this embodiment, when water flows over the device seat 1, the impact of the water body causes the cup wheel 25 to rotate continuously, and the cup wheel 25 drives the cam 30 to rotate, thereby cooperating with the return spring 32 to make the two pistons 31 reciprocate horizontally, and then pump air into the jet box 26 through the inlet pipe 28 and the outlet pipe 29, and spray it out from each jet tube 27, generating a certain airflow impulse, thereby flushing away the aquatic plants, debris and mud in the water body at the opening of the jet tube 27, preventing these water substances from being wrapped into the first transmission mechanism and the second transmission mechanism, ensuring the normal operation of the first transmission mechanism and the second transmission mechanism, and then ensuring the normal operation of the entire monitoring device.
