Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, specifically relating to an adjustable-height river water quality testing buoy support. Background Technology

[0002] Economic development and population growth have also brought about very serious environmental pollution problems, with river pollution being particularly prominent. Pollution is particularly severe in cities and river sections with concentrated industrial activity, with industrial wastewater and domestic sewage being the main sources. A search revealed application number "CN202321296729.9" disclosing "A Water Quality Monitoring Buoy Station," which describes "connecting the fixed part of a lifting assembly to a buoy assembly, allowing the fixed part to float on the water surface, and simultaneously connecting a monitoring unit to the telescopic part of the lifting assembly, allowing the monitoring unit to move with the telescopic part of the lifting assembly, thus enabling the monitoring unit to move to different depths in the water body and monitor the water quality at different depths." While this method of connecting the fixed part of the lifting assembly to a buoy assembly, allowing the fixed part to float on the water surface, and connecting the monitoring unit to the telescopic part of the lifting assembly, enabling the monitoring unit to move to different depths in the water body and monitor the water quality at different depths, the above-mentioned document still has the following problems in practical use:

[0003] In actual use, after the height is adjusted, it cannot be reinforced and fixed, which makes the winch prone to sudden rotation due to excessive force, resulting in inaccurate detection. In addition, the counterweight cannot be adjusted during use, causing the rapid current to shake violently. And the rope is prone to damage when dragging heavy objects.

[0004] Therefore, providing a bracket that can be fixed after height adjustment and can also adjust the counterweight is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-height river water quality monitoring buoy support, aiming to solve the aforementioned technical problems.

[0006] This utility model provides an adjustable height river water quality monitoring buoy support, including a connecting box, a stable height adjustment component, and a counterweight adjustment component.

[0007] The top of the connecting box is provided with a protective shell, the inside of the protective shell is provided with a storage battery, the bottom of the connecting box is provided with an auxiliary plate, and the bottom of the auxiliary plate is provided with an airbag.

[0008] The stable height adjustment assembly includes a torque motor disposed on one side of the connecting box. The output shaft end of the torque motor passes through the inner wall of the connecting box and is provided with a rotating rod. A winding reel is provided on the outer wall of the rotating rod. A steel wire rope is wound inside the winding reel. A gear is provided on one side of the outer wall of the rotating rod. Several electric telescopic rods are provided at the top and bottom of the inner wall of the connecting box. Two racks are provided at the ends of the several electric telescopic rods.

[0009] The counterweight adjustment assembly includes a water tank located at the bottom of the wire rope, a sealed box at the bottom of the water tank, a heating plate in the middle of the inner wall of the sealed box, a water pump on one side of the top of the inner wall of the sealed box, a connecting pipe sealed to one end of the water pump, a one-way valve sealed to one end of the connecting pipe passing through the sealed box, a discharge pipe sealed to the top of the water pump, and a pressure pump on the other side of the top of the inner wall of the sealed box, with an auxiliary pipe sealed to one end of the pressure pump.

[0010] In one embodiment of this utility model, one end of the water tank is sealed and connected to a waterproof electric valve, and a liquid level sensor is provided on the inner wall of the water tank.

[0011] In one embodiment of this utility model, a counterweight is provided at the bottom of the sealed box, a water quality detector is provided at the bottom of the counterweight, and a plurality of acceleration wave sensors are provided on the outer wall of the counterweight.

[0012] In one embodiment of this utility model, a protective cover is provided at one end of both the water tank and the sealing box.

[0013] In one embodiment of this utility model, two laser rangefinders are provided at the bottom of the auxiliary plate.

[0014] In one embodiment of this utility model, one side of the rotating rod is rotatably connected to the other side of the inner wall of the connecting box, the middle of the two racks corresponds to the gear, the end of the auxiliary tube is sealed and connected to the water tank, and a controller is provided at one corner of the connecting box.

[0015] In one embodiment of this utility model, the torque motor, electric telescopic rod, heating plate, water pump, pressurizing pump, waterproof electric valve, liquid level sensor, water quality detector, accelerometer wave sensor and laser rangefinder are all electrically connected to the controller, and the controller is electrically connected to the battery.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) When adjusting the height, the controller will turn on the torque motor, which will drive the rotating rod to rotate, and then drive the take-up reel to rotate, causing the take-up reel to release the wire rope. This will cause the bottom parts of the wire rope to move downwards, thus achieving height adjustment. When the adjustment is complete and needs to be maintained, the controller will turn off the torque motor and open the electric telescopic rod, causing the electric telescopic rod to drive the rack and pinion to engage the gear, thereby limiting the rotating rod and take-up reel. This is convenient for limiting the rotating rod and take-up reel during use, preventing the torque motor output shaft and rotating rod from suddenly rotating due to force on the take-up reel, which would cause the bottom water quality detector to suddenly drop, resulting in inaccurate monitoring. This achieves the purpose of stable height adjustment.

[0018] 2) When the accelerated wave sensor detects large waves nearby, it feeds the information back to the controller. The controller then activates the water pump, drawing water from the river through connecting pipes and a one-way valve. This water is then discharged into the tank via a discharge pipe, increasing the tank's weight. The water level sensor monitors the water level in the tank, and the controller calculates the weight, adding enough water to counteract the waves. This allows the water in the tank to work in conjunction with the counterweight, mitigating the impact of the waves and reducing swaying. Conversely, when the waves are small, the controller activates the booster pump and a waterproof electric valve. The booster pump pressurizes the tank through an auxiliary pipe, allowing the water to be discharged through the waterproof electric valve, thus reducing the weight to match the wave's intensity. This allows for millisecond-level anti-phase compensation for waves, currents, and wind, enabling the sensor to increase weight to resist rapid currents in fast-flowing areas and decrease weight to reduce resistance in calm conditions. This also reduces the stress on the wire rope and winding reel, increasing their lifespan and minimizing damage, resulting in more accurate detection results. Attached Figure Description

Detailed Implementation

[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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figure 1-4 An adjustable-height river water quality monitoring buoy support includes a connecting box 100, a stable height adjustment component 200, and a counterweight adjustment component 300.

[0028] Please refer to the details. Figure 1 The top of the connector box 100 is provided with a protective shell 110, and the inside of the protective shell 110 is provided with a storage battery. The bottom of the connector box 100 is provided with an auxiliary plate 120, and the bottom of the auxiliary plate 120 is provided with an airbag 130.

[0029] Please see Figure 2 The stable height adjustment component 200 includes a torque motor 210 disposed on one side of the connecting box 100. The output shaft end of the torque motor 210 passes through the inner wall of the connecting box 100 and is provided with a rotating rod 220. A winding reel 230 is provided on the outer wall of the rotating rod 220. A steel wire rope 240 is wound inside the winding reel 230. A gear 250 is provided on one side of the outer wall of the rotating rod 220. Several electric telescopic rods 260 are provided at the top and bottom of the inner wall of the connecting box 100. Two racks 270 are provided at the ends of the several electric telescopic rods 260.

[0030] In one specific embodiment, the included torque motor 210 allows the controller to activate it during height adjustment. The torque motor 210 drives the rotating rod 220 to rotate, which in turn drives the take-up reel 230 to rotate. This causes the take-up reel 230 to release the wire rope 240, allowing the bottom parts of the wire rope 240 to move downwards, thus achieving height adjustment. When the adjustment is complete and needs to be maintained, the controller deactivates the torque motor 210 and activates the electric telescopic rod 260. The electric telescopic rod 260 drives the rack 270 to engage the gear 250, thereby limiting the rotation of the rotating rod 220 and the take-up reel 230. This ensures that the rotating rod 220 and the take-up reel 230 are kept in place during use, preventing sudden rotation of the torque motor 210 output shaft and the rotating rod 220 due to force on the take-up reel 230. Such sudden rotation of the take-up reel 230 could cause the bottom water quality detector 600 to suddenly drop, leading to inaccurate monitoring. This achieves stable height adjustment.

[0031] Please see Figure 3-4 The counterweight adjustment assembly 300 includes a water tank 310 located at the bottom of the wire rope 240, a sealed box 320 located at the bottom of the water tank 310, a heating plate located in the middle of the inner wall of the sealed box 320, a water pump 330 located on one side of the top of the inner wall of the sealed box 320, a connecting pipe 340 sealed to one end of the water pump 330, a one-way valve 350 sealed to one end of the connecting pipe 340 passing through the sealed box 320, a discharge pipe 360 ​​sealed to the top of the water pump 330, and the end of the discharge pipe 360 ​​passing through the sealed box 320 and sealed to the water tank 310. A pressure pump 370 is located on the other side of the top of the inner wall of the sealed box 320, and an auxiliary pipe 380 sealed to one end of the pressure pump 370.

[0032] In one specific embodiment, the water tank 310 facilitates the use of a wave sensor 700 to detect large waves in the vicinity. When the sensor detects large waves, it feeds this information back to the controller, which then activates the water pump 330. This pump draws water from the river through the connecting pipe 340 and the one-way valve 350, and delivers it to the water tank 310 through the discharge pipe 360. This increases the weight of the water tank 310. A level sensor monitors the water level in the tank, and the controller calculates the weight, adding enough water to counteract the waves. This allows the water in the tank 310 to work in conjunction with the counterweight 500, mitigating the impact of the waves. The controller reduces swaying when the waves are smaller. Conversely, when the waves are smaller, the controller will open the pressurization pump 370 and the waterproof electric valve 400, so that the pressurization pump 370 pressurizes the water tank 310 through the auxiliary pipe 380, and then discharges the water in the water tank 310 through the waterproof electric valve 400, thereby reducing the weight to match the weight of the waves. It can perform millisecond-level anti-phase compensation for waves, water flow and wind, so as to increase the weight to resist the rapid current in the rapid current, and reduce the counterweight to reduce resistance in the calm water, reduce the force on the wire rope 240 and the winding reel 230, increase their service life and make them less prone to damage, and make the detection results more accurate.

[0033] Please see Figure 4 One end of the water tank 310 is sealed and connected to a waterproof electric valve 400, and a liquid level sensor is installed on the inner wall of the water tank 310.

[0034] In one specific embodiment, a liquid level sensor is provided to facilitate real-time monitoring of the water in the water tank 310, so as to calculate the weight in conjunction with the area of ​​the water tank 310, and to monitor the counterweight in real time during use.

[0035] Please see Figure 3 The bottom of the sealed box 320 is equipped with a counterweight 500, the bottom of the counterweight 500 is equipped with a water quality detector 600, and the outer wall of the counterweight 500 is equipped with several acceleration wave sensors 700.

[0036] In one specific embodiment, the provided counterweight 500 facilitates the initial entry into the river during use, and works in conjunction with the water tank 310 to allow for precise adjustment of the counterweight weight during use.

[0037] Please see Figure 3 Both the water tank 310 and the sealing box 320 are equipped with a protective cover 800 at one end.

[0038] In one specific embodiment, the protective cover 800 allows for the use of a filter screen on the cover 800 during use, effectively preventing other impurities from entering the water tank 310 and causing blockages that would prevent the counterweight from being adjusted.

[0039] Please see Figure 3 Two laser rangefinders 900 are installed at the bottom of the auxiliary plate 120.

[0040] In one specific embodiment, the laser rangefinder 900 is provided so that the water tank 310 can be scanned during use, and the distance between the water tank 310 and the water quality detector 600 can be subtracted to monitor its position in real time, so as to achieve the purpose of detecting water at different heights.

[0041] Please see Figure 1-4 One side of the rotating rod 220 is rotatably connected to the other side of the inner wall of the connecting box 100. The middle of the two racks 270 are respectively aligned with the gears 250. The end of the auxiliary pipe 380 is sealed and connected to the water tank 310. A controller is provided at one corner of the connecting box 100.

[0042] In one specific embodiment, the connection box 100 is provided to protect the parts inside the connection box 100 during use, thus preventing them from being damaged by bumps or knocks.

[0043] Please see Figure 1-4 The torque motor 210, electric telescopic rod 260, heating plate, water pump 330, pressurizing pump 370, waterproof electric valve 400, liquid level sensor, water quality detector 600, acceleration wave sensor 700 and laser rangefinder 900 are all electrically connected to the controller, and the controller is electrically connected to the battery.

[0044] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0045] In use, the torque motor 210 is first activated by the controller when adjusting the height. The torque motor 210 drives the rotating rod 220 to rotate, which in turn drives the winding reel 230 to rotate, causing the winding reel 230 to release the wire rope 240. This causes the bottom parts of the wire rope 240 to move downwards, achieving height adjustment. When the adjustment is complete and needs to be maintained, the controller deactivates the torque motor 210 and activates the electric telescopic rod 260. The electric telescopic rod 260 then drives the rack 270 to engage the gear 250. Then, the rotating rod 220 and the winding reel 230 are limited, which facilitates the limiting of the rotating rod 220 and the winding reel 230 during use. This prevents the output shaft of the torque motor 210 and the rotating rod 220 from suddenly rotating due to force on the winding reel 230, which would cause the bottom water quality detector 600 to suddenly drop, resulting in inaccurate monitoring. This achieves the purpose of stable height adjustment. Then, through the provided water tank 310, when the acceleration wave sensor 700 detects large waves nearby, it can feed back the information to... The controller will activate water pump 330, causing it to draw water from the river through connecting pipe 340 and one-way valve 350, and then send it to water tank 310 through discharge pipe 360, increasing the weight of water tank 310. A level sensor monitors the water level in water tank 310, and the controller calculates the weight, adding enough water to counteract the waves. This allows the water in water tank 310 to work in conjunction with counterweight 500 to mitigate the impact of waves and reduce swaying. Conversely, when the waves are relatively small, the controller will finally open the additional... The pressure pump 370 and the waterproof electric valve 400 pressurize the water tank 310 through the auxiliary pipe 380, thereby discharging the water in the water tank 310 through the waterproof electric valve 400. This reduces the weight, making it match the weight of the waves. It can perform millisecond-level anti-phase compensation for waves, water flow and wind, thereby increasing the weight to resist the rapid current in the rapid current and reducing the counterweight to reduce resistance in the calm water. It also reduces the force on the wire rope 240 and the winding reel 230, increases their service life and makes them less prone to damage, and makes the test results more accurate.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
