Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy detection devices, and in particular to a water conservancy engineering detection device based on the Internet of Things. Background Art

[0002] Water conservancy detection devices are mainly used to monitor the water conservancy operations of rivers, lakes, and reservoirs, and to promptly respond to the hydrological characteristics of each water area so that relevant departments can make arrangements to prevent flood disasters. Water conservancy project detection devices use various detectors to detect water conservancy temperature, humidity and other information for detection. The Internet of Things-based detection water conservancy detection device shares all the detector sensors in it with the Internet of Things technology network, allowing staff to observe the data detected and uploaded by the detector sensors at a specific platform port.

[0003] However, when the existing water conservancy detection device detects temperature and other information in areas with turbulent water flow, the turbulent water flow will carry some floating objects towards the detection device, and the floating objects will block the sensor part of the detection device, causing the detection device to fail to work normally or provide accurate temperature data. In response to the above problems, the patent publication number "CN117129093A" discloses a water conservancy monitoring device for water conservancy projects, including a fixing seat, the top of which is fixedly connected to a mounting plate by a support, the top of which is fixedly connected to a monitoring device body by bolts, and also includes an anti-shielding device, an anti-adhesion device, a protective device and a stabilizing device.

[0004] Although the technical solution of the above patent has a certain effect of repelling floating objects in the water, when the water flow contains a lot of aquatic plants, the aquatic plants are long and easy to get entangled. The anti-attachment device in the above technical solution has extremely limited effect on their removal. Aquatic plants and larger floating objects will still approach the main body of the detection equipment and block it, which is not conducive to its detection work. Summary of the invention

A pair of the T-shaped blocks are respectively slidably connected in a pair of strip grooves opened in the base, and the arc-shaped fixing plate is respectively fixed to the arc-shaped rubber gasket and the T-shaped block;

[0010] The positioning and stabilizing component is driven by a flow-blocking pneumatic component.

[0011] Preferably, the baffle pneumatic assembly consists of an arc-shaped baffle plate, a slider, a first bellows and a first air guide tube, and is used to convert the impact force of the water body into the pressure of the gas flow. A slide groove is opened on the side of the base, and a pair of sliders are slidably connected in the slide groove and movably connected to the two sides of the arc-shaped baffle plate through a connecting rod. The first bellows is elastically connected between the inner wall of the slide groove and the slider and is connected to the first air guide tube. The positioning and stabilization assembly is connected to the baffle pneumatic assembly through a pneumatic mechanism.

[0012] Preferably, the pneumatic mechanism comprises a pneumatic box and a piston, the pneumatic box is fixed on the side wall of the base, the piston is sealingly slidably connected between the inner walls of the pneumatic box and fixedly connected to the T-block through a push rod, and the pneumatic box is connected to the first air duct.

[0013] Preferably, the transmission mechanism includes a reciprocating screw and a sub-gear, the reciprocating screw is rotatably connected between the base and the top plate, a screw nut is threadedly connected to the reciprocating screw, the sub-gear is fixed to the upper end of the reciprocating screw and meshes with the main gear, and the cutting blade is fixed to the side wall of the screw nut.

[0014] Preferably, the cutting blade comprises a tool holder part and a blade part, the tool holder part is arc-shaped and fixed to the lead screw nut, and the blade part comprises a plurality of blades and the plurality of blades are evenly distributed on the outer arc surface of the tool holder part.

[0015] Preferably, it also includes a negative pressure stabilization component, which is composed of a support leg, a negative pressure suction cup and a second bellows, and is used to convert the impact force of the water flow into the negative pressure suction force of the device. The four support legs are symmetrically fixed at the lower end of the base, the negative pressure suction cup is fixed at the lower end of the support legs and is connected to the support legs, and the negative pressure stabilization component is connected to the flow-blocking pneumatic component through a negative pressure generating mechanism.

[0016] Preferably, the negative pressure generating mechanism includes an L-shaped connecting rod and a second air duct, a pair of the L-shaped connecting rods are respectively fixedly connected to a pair of sliders and two ends of the second bellows, one end of the second air duct is connected to the second bellows, and the other end is connected to the negative pressure suction cup.

[0017] Preferably, the arc-shaped baffle is of a retractable design, with slots at both the upper and lower ends, and the slots are movably connected to a combined telescopic plate through an electric push rod. A vibration sensor is installed on the detection equipment body to monitor the vibration amplitude data of the detection equipment body.

[0018] Preferably, a group of first reset springs are elastically connected between the pair of sliders, and are used to pull the sliders to reset the first bellows when the impact force of the water flow decreases.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting up an anti-attachment cutting component, when water flows through the device, the water flow will drive the annular push plate to rotate, and push away the floating objects carried in the water flow, so that the floating objects are away from the main body of the detection equipment. At the same time, the main gear meshes with the sub-gear to rotate, and each sub-gear drives each reciprocating screw to rotate, thereby driving the cutting blade to move vertically back and forth through the screw nut to cut and crush the water plants and large floating objects in the water flow, and cooperate with the driving effect of the annular push plate under the rotation, so as to prevent the water plants and large floating objects from entangled with the main body of the detection equipment to block it, so as to ensure the normal operation of each detector and detector in the main body of the detection equipment and upload data to the Internet platform port;

[0021] 2. By setting the flow-blocking pneumatic component and the positioning and stabilizing component, when the water flow velocity is too fast and the impact force is too large, the arc-shaped flow-blocking plate will move backward under the impact force of the water flow. At this time, under the action of the transfer rod, the two sliders slide to both sides, thereby squeezing the first bellows, so that the air in the first bellows enters the pneumatic box through the first air guide pipe, thereby pushing the piston to slide under the action of increased air pressure, and then pushing the T-shaped block and the arc-shaped fixing plate to move to the middle through the push rod, so that the arc-shaped rubber gasket clamps the main body of the detection equipment firmly, which not only avoids the damage of the main body of the detection equipment under the impact of the water flow, but also avoids the shaking of the main body of the detection equipment, and can ensure the normal detection and networking of the detectors and sensors in the main body of the detection equipment;

[0022] 3. By setting up a negative pressure stabilizing mechanism, when the impact force of the water flow is too large, the arc-shaped baffle is impacted and moved backwards, and the slider slides to both sides under the action of the transfer rod. At the same time, the two sliders stretch the second bellows through the L-shaped connecting rod, so that the air pressure in the second bellows is reduced to generate negative pressure. At this time, the air in the negative pressure suction cup is sucked into the second bellows through the second air guide pipe, and negative pressure is also generated in the negative pressure suction cup, so that the whole device is more firmly adsorbed in a fixed position, avoiding the problem of shaking of the base caused by the impact of water, thereby further ensuring the normal detection and networking of the detectors and sensors in the main body of the detection equipment.

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1

[0035] The anti-attachment cutting component 4 consists of a main gear 401, an annular push plate 402 and a cutting blade 403, which is used to cut and drive away floating objects and aquatic plants in the water body. The annular push plate 402 is fixed under the main gear 401, and the cutting blade 403 is connected to the main gear 401 through a transmission mechanism.

[0036] The transmission mechanism includes a reciprocating screw 404 and a sub-gear 405. The reciprocating screw 404 is rotatably connected between the base 1 and the top plate 2. A screw nut 406 is threadedly connected to the reciprocating screw 404. The sub-gear 405 is fixed to the upper end of the reciprocating screw 404 and meshes with the main gear 401. The cutting blade 403 is fixed to the side wall of the screw nut 406.

[0037] The cutting blade 403 includes a tool holder part and a blade part. The tool holder part is arc-shaped and fixed to the lead screw nut 406. The blade part includes a plurality of blades and the plurality of blades are evenly distributed on the outer arc surface of the tool holder part.

[0038] The baffle pneumatic assembly 5 is composed of an arc baffle plate 501, a slider 502, a first bellows 504 and a first air guide pipe 505, and is used to convert the impact force of the water body into the pressure of the gas flow. A slide groove 102 is opened on the side of the base 1, and a pair of sliders 502 are slidably connected in the slide groove 102 and movably connected to both sides of the arc baffle plate 501 through a transfer rod 503. The first bellows 504 is elastically connected between the inner wall of the slide groove 102 and the slider 502 and is connected to the first air guide pipe 505;

[0039] The positioning and stabilizing component 6 includes a T-shaped block 602, an arc-shaped fixing plate 604 and an arc-shaped rubber gasket 605, and is used to firmly clamp the detection device body 3 when the impact force of the water flow is too large. A stack of strip grooves 101 are symmetrically opened on the upper end of the base 1, and a pair of T-shaped blocks 602 are respectively slidably connected in a pair of strip grooves 101. One end of the arc-shaped fixing plate 604 is fixed to the arc-shaped rubber gasket 605, and the other end is fixed to the T-shaped block 602 through a bending rod 603;

[0040] The positioning and stabilizing component 6 is connected to the flow-blocking pneumatic component 5 through a pneumatic mechanism, and the pneumatic mechanism includes a pneumatic box 601 and a piston 606. The pneumatic box 601 is fixed on the side wall of the base 1, and the piston 606 is sealingly and slidably connected between the inner walls of the pneumatic box 601 and fixedly connected to the T-block 602 through a push rod 607. The pneumatic box 601 is connected to the first air duct 505.

[0041] A group of first return springs are elastically connected between the pair of sliders 502, and are used to pull the sliders 502 to return the first bellows 504 to its original position when the impact force of the water flow decreases.

[0042] In this embodiment, the base 1 is fixed in the water body, and the detection equipment body 3 is installed above the base 1. The detectors and sensors therein are connected to the Internet. A series of data such as the water temperature, water level, and water flow rate detected by the base 1 are uploaded to a specific platform via the Internet for staff to judge and operate. The Internet of Things technology is an existing mature technology and will not be elaborated here.

[0043] When water flows through the device, the water flow will drive the annular push plate 402 to rotate, and push away the floating objects carried in the water flow, so that the floating objects are away from the detection equipment body 3. At the same time, the main gear 401 engages the sub-gear 405 to rotate, and each sub-gear 405 drives each reciprocating screw 404 to rotate, thereby driving the cutting blade 403 to move vertically back and forth through the screw nut 406, cutting and crushing the aquatic plants and large floating objects in the water flow, and cooperating with the driving effect of the rotation of the annular push plate, so as to prevent the aquatic plants and large floating objects from being entangled on the detection equipment body 3 and blocking it, thereby ensuring that each detector and detector in the detection equipment body 3 works normally and uploads data to the Internet platform port.

[0044] When the water flow rate is too fast and the impact force is too large, the arc-shaped baffle plate 501 will move backwards under the impact force of the water flow. At this time, under the action of the adapter rod 503, the two sliders 502 slide to both sides, thereby squeezing the first bellows 504, so that the air in the first bellows 504 enters the pneumatic box 601 through the first air guide pipe 505, thereby pushing the piston 606 to slide under the action of increased air pressure, and then pushing the T-shaped block 602 and the arc-shaped fixing plate 604 to move toward the middle through the push rod 607, so that the arc-shaped rubber gasket 605 clamps the detection device body 3 firmly, which not only avoids the detection device body 3 from being damaged under the impact of the water flow, but also avoids the shaking of the detection device body 3, which can ensure the normal detection and networking of the detectors and sensors in the detection device body 3.

[0045] Embodiment 2

[0046] Reference Figure 7-8 , which is different from the first embodiment in that it also includes a negative pressure stabilizing component 7, which is composed of a support leg 701, a negative pressure suction cup 702 and a second bellows 703, and is used to convert the impact force of the water flow into the negative pressure suction force of the device. The four support legs 701 are symmetrically fixed at the lower end of the base 1, the negative pressure suction cup 702 is fixed at the lower end of the support leg 701 and is connected to the support leg 701, and the negative pressure stabilizing component 7 is connected to the flow-blocking pneumatic component 5 through a negative pressure generating mechanism.

[0047] The negative pressure generating mechanism includes an L-shaped connecting rod 704 and a second air guide tube 705. A pair of L-shaped connecting rods 704 are respectively fixedly connected to a pair of sliders 502 and two ends of the second bellows 703. One end of the second air guide tube 705 is connected to the second bellows 703, and the other end is connected to the negative pressure suction cup 702.

[0048] In this embodiment, when the impact force of the water flow is too large, the arc-shaped baffle plate 501 is impacted and moved backwards, and the slider 502 slides to both sides under the action of the transfer rod 503. At the same time, the two sliders 502 stretch the second bellows 703 through the L-shaped connecting rod 704, so that the air pressure in the second bellows 703 is reduced to generate negative pressure. At this time, the air in the negative pressure suction cup 702 is sucked into the second bellows 703 through the second air guide tube 705, and negative pressure is also generated in the negative pressure suction cup 702, so that the entire device is more firmly adsorbed in a fixed position, avoiding the problem of shaking of the base 1 caused by the impact of the water body, thereby further ensuring the normal detection and networking of the detectors and sensors in the detection equipment body 3.

[0049] Embodiment 3

[0050] The difference from the above-mentioned embodiment 1 and embodiment 2 is that the arc-shaped baffle plate 501 is designed for storage, and slots are provided at the upper and lower ends, and the slots are movably connected to the combined telescopic plates through electric push rods. A vibration sensor is installed on the detection equipment body 3 to monitor the vibration amplitude data of the detection equipment body.

[0051] In this embodiment, the original cross-sectional area of ​​the arc-shaped baffle plate 501 is relatively small, and will not cause excessive obstruction to the flow of water, so that the water flows through the detection device at its normal flow rate, thereby ensuring that the data values ​​detected by the detection device body 3 are all values ​​under normal conditions, ensuring its normal detection and data upload work. When and only when the impact force of the water flow is too large and the detection device body 3 produces a large shake, the vibration sensor inside it detects the vibration data and uploads it to the Internet of Things port platform. After observing the vibration data, the staff controls a pair of combined telescopic plates to open to the upper and lower ends, thereby increasing its baffle area, so as to realize the functions of the first and second embodiments, and further ensure that the detectors and sensors in the detection device body 3 work normally in the detection and networking.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
