Description

Technical Field

[0001] This invention belongs to the field of rainwater detection technology, and in particular relates to an intelligent rainwater pH detection device. Background Technology

[0002] With increasing environmental awareness and in-depth research on acid rain, intelligent rainwater pH testing equipment plays a crucial role in environmental monitoring. This type of equipment can automatically and in real-time collect rainwater samples and accurately measure their pH, providing key basic data for assessing regional precipitation pollution, studying the formation mechanism of acid rain, and its environmental impact.

[0003] Common intelligent rainwater pH testing equipment typically has a water collection hopper fixedly installed on top to collect and guide rainwater into the subsequent testing system. This hopper is generally open, of fixed size, and directly exposed to the external environment. Its structure is usually relatively simple, securely connected to the main body of the equipment via rigid supports to ensure stability during rainwater collection. This design primarily focuses on achieving basic water collection functionality.

[0004] However, existing rainwater collection hopper designs have significant drawbacks: First, their fixed size prevents flexible adjustment of the collection area or capacity based on actual rainfall intensity (light, moderate, or heavy rain). In light rain, insufficient samples may be collected, while in heavy rain, overflow or inefficient collection may occur, making them unsuitable for efficient rainwater collection under varying rainfall conditions. Second, the collection hoppers cannot be stored or shielded, leaving them exposed during non-rainy periods. This exposure easily leads to the accumulation of dust, fallen leaves, bird droppings, and other impurities. These contaminants not only pollute subsequently collected rainwater samples, causing distorted and inaccurate test results, but also clog pipes, increasing maintenance difficulty and frequency. More seriously, in windy conditions, the fixed, open collection hopper acts like a "sail," significantly increasing the overall windward area and wind load on the equipment. This causes excessive overturning moments or vibrations, easily leading to structural damage, loosening of supports, or even complete collapse, severely threatening the equipment's operational safety and lifespan. Summary of the Invention

A connecting rod is connected to the bottom of the lifting frame. A mating groove is provided on the connecting rod along its length. An installation groove is provided within the stepped main body. A compression spring is fixedly connected to the bottom of the installation groove. The top of the compression spring is connected to the bottom of the connecting rod.

[0011] A further technical solution is provided on the stepped main body, which is equipped with a rinsing assembly. The rinsing assembly includes an annular water tank fixed on the stepped main body, a water pump fixed on the top of the annular water tank, the input end of the water pump extending into the annular water tank, and the output end of the annular water tank extending into the detection chamber through a connecting water pipe.

[0012] A further technical solution includes a water sample storage mechanism on the stepped main body. The water sample storage mechanism includes a fixed annular track inside the stepped main body, an annular workstation frame rotatably connected inside the annular track, a rotating component at the bottom of the stepped main body for driving the annular workstation frame to rotate, multiple collection slots evenly arranged in a ring at the top of the annular workstation frame, each collection slot containing a collection bucket, a guide groove at the bottom of the detection chamber, a water inlet shell slidably connected inside the guide groove, multiple water inlet holes on the side wall of the water inlet shell, a second compression spring connected to the top of the guide groove, the end of the second compression spring connected to the water inlet shell, a water inlet notch at the top of the annular track, the water inlet notch located below the guide groove and communicating with the guide groove, and an upper push component located below the annular workstation frame inside the stepped main body, the upper push component being located directly below the guide groove, the upper push component being used to push the collection bucket upwards.

During light rain, the water collection area can be expanded to ensure sufficient sample volume; during heavy rain, the water collection area can be reduced or switched to an inverted cone-shaped drainage state to avoid overflow and contamination of samples. The folding rod is vertically retracted, and the protective cover moves up to completely cover the water collection structure, isolating pollutants such as dust, fallen leaves, and bird droppings. After being stored, the windward area of ​​the equipment is significantly reduced, reducing the risk of wind-induced overturning. 2. The water collection hopper status is linked to the detection process. After the water level sensor triggers the sample volume to reach the standard, it automatically switches to the drainage state to remove excess rainwater. 3. The flushing components are regularly sprayed with cleaning solution to flush the detection chamber, pipes and the inner wall of the water collection tank, solving the problems of residual corrosion and cross-contamination. In addition, the retractable water collection tank reduces the use of cleaning solution. 4. When abnormal data is triggered, the top component pushes the collection bucket into the bottom of the detection chamber, the water inlet shell opens the channel, and the sample is stored in a specific direction.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, an intelligent rainwater pH detection device according to an embodiment of the present invention includes a stepped main body 101 and a pipe 108 arranged along the axis of the top of the stepped main body 101. The lower end of the pipe 108 is connected to a rainwater pH detection module. The rainwater pH detection module includes a detection chamber 109 disposed within the stepped main body 101. A water level sensor 110 and a pH detection sensor 111 are sequentially fixed on the inner wall of the detection chamber 109 from top to bottom. A drain pipe penetrating the side wall of the stepped main body 101 is connected to the bottom of the detection chamber 109. A solenoid valve 114 is installed on the drain pipe. The top of the detection chamber 109 communicates with the pipe 108. The stepped main body 101 has a protective sleeve 102 that slides along its length on the side wall, and multiple folding rods 103 that are hinged to the top of the stepped main body 101. The multiple folding rods 103 are evenly distributed in a ring, and a water collection layer 104 is connected between every two folding rods 103. The water collection layer 104 is made of elastic material. A lifting component 2 is provided on the side wall of the stepped main body 101. The lifting component 2 is used to drive the protective sleeve 102 to move up and down. A transmission component 3 is provided inside the stepped main body 101. The transmission component 3 drives the multiple folding rods 103 to rotate synchronously upward or downward through the lifting component 2. When the multiple folding rods 103 are tilted upward, the multiple water collection layers 104 form a water collection bucket.

[0021] In this embodiment of the invention, in the initial state, multiple folding rods 103 are rotated upwards to a vertical position, and a protective sleeve 102 covers the multiple folding rods 103 and multiple water collection layers 104 (e.g., Figure 6 As shown), during use, the lifting assembly 2 moves the protective sleeve 102 downwards, positioning it below the multiple folding rods 103. The transmission assembly 3, through the lifting assembly 2, drives the multiple folding rods 103 to rotate downwards synchronously until the multiple folding rods 103 tilt upwards. At this point, the multiple folding rods 103 drive multiple water collection layers 104 to form a water collection hopper (as shown). Figure 1 As shown), the water collection bucket is used to collect rainwater. The angle of multiple folding rods 103 is adjusted according to the rainfall amount, thereby adjusting the area of ​​the water collection bucket to complete the rainwater collection within a specified time. The collected rainwater enters the detection chamber 109 through the pipe 108. When the water level in the detection chamber 109 submerges the water level sensor 110, the rainwater sample volume in the detection chamber 109 reaches the standard. The transmission assembly 3 drives the multiple folding rods 103 to rotate downwards synchronously through the lifting assembly 2 until the multiple folding rods 103 and the multiple water collection layers 104 are aligned. Figure 7 The inverted cone shape shown pours out excess rainwater from the water collection hopper and stops collecting rainwater. After the pH detection sensor 111 detects the rainwater, the detection data is transmitted to the storage module for storage. The solenoid valve 114 opens the drain pipe connected to the bottom of the detection chamber 109 to drain the rainwater from the detection chamber 109. During the next rainwater detection period, solenoid valve 114 closes the drain pipe connected to the bottom of detection chamber 109. Transmission assembly 3, through lifting assembly 2, drives multiple folding rods 103 to rotate downwards synchronously until the multiple folding rods 103 tilt upwards. At this point, the multiple folding rods 103 drive multiple water collection layers 104 to form a water collection hopper (e.g., ...). Figure 1 As shown), rainwater is collected again. By switching the states of multiple folding rods 103 and multiple water collection layers 104, excess rainwater in the water collection bucket can be poured out after a rainwater detection, so as to avoid the residual rainwater in the water collection bucket affecting the accuracy of rainwater detection in the next time period. When there is a strong wind or the equipment is not in use, the transmission component 3 drives the multiple folding rods 103 to rotate upward synchronously through the lifting component 2 until the multiple folding rods 103 are vertically upward. The lifting component 2 then drives the protective sleeve 102 to cover the folding rods 103 and the water collection layer 104, thereby preventing impurities from remaining in the water collection hopper and from being damaged by strong winds.

[0022] like Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, the lifting assembly 2 includes a guide groove 201 arranged along the length direction on the side wall of the stepped main body 101, a guide block 202 fixed on the inner wall of the protective sleeve 102, the guide block 202 being slidably connected in the guide groove 201, a lead screw 203 being rotatably connected in the guide groove 201, the lead screw 203 passing through the guide block 202 and being threadedly connected to the guide block 202, and a motor 204 fixed at the bottom of the stepped main body 101, the rotating end of the motor 204 being connected to the lead screw 203.

[0023] In this embodiment of the invention, motor 204 drives lead screw 203 to rotate. Under the guidance of guide groove 201, the rotating lead screw 203 drives guide block 202 to move up and down through threaded transmission. Guide block 202 drives protective sleeve 102 to move up and down.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the transmission assembly 3 includes a lifting frame 301 slidably connected along the length of a stepped main body 101. Multiple L-shaped transmission rods 302 are fixedly mounted on the side wall of the lifting frame 301. A fixed shaft 303 is fixedly mounted at the top of each of the multiple L-shaped transmission rods 302. A transmission groove 304 is provided along the length of the bottom of each of the multiple folding rods 103. The multiple fixed shafts 303 are slidably connected within the multiple transmission grooves 304. A connecting rod 305 is connected to the bottom of the lifting frame 301. A mating groove 306 is provided along the length of the connecting rod 305. An installation groove 308 is provided within the stepped main body 101. A compression spring 307 is fixedly connected to the bottom of the installation groove 308. The top of the compression spring 307 is connected to the bottom of the connecting rod 305. A push block 309 is fixedly mounted on the guide block 202 and is disposed within the mating groove 306.

[0025] In this embodiment of the invention, in the initial state, the compression spring 307 pushes the connecting rod 305 upward, the connecting rod 305 drives the lifting frame 301 to move upward, the lifting frame 301 drives multiple L-shaped transmission rods 302 to move upward, the multiple L-shaped transmission rods 302 drive multiple fixed shafts 303 to move upward, the multiple fixed shafts 303 push multiple folding rods 103 to a vertical state through multiple transmission grooves 304, and the protective sleeve 102 covers the multiple folding rods 103 and multiple water collection layers 104; During rainwater collection and testing, motor 204 drives lead screw 203 to rotate. Guided by guide trough 201, the rotating lead screw 203 drives guide block 202 downward through threaded transmission. Guide block 202 drives protective sleeve 102 and push block 309 downward. Push block 309 moves downward within mating groove 306 of connecting rod 305 until it contacts the bottom of mating groove 306. At this time, protective sleeve 102 is located below multiple folding rods 103 and multiple water collection layers 104. As guide block 202 continues to drive protective sleeve 102 and push block 309 downward, push block 309 overcomes the elastic force of compression spring 307 and pushes connecting rod 305 downward. Connecting rod 305 drives lifting frame 301 downward. Lifting frame 301 drives multiple L-shaped transmission rods 302 downward. 2. Multiple fixed shafts 303 move downwards, and multiple fixed shafts 303 drive multiple folding rods 103 to rotate downwards through multiple transmission slots 304. The multiple folding rods 103 expand multiple water collection layers 104. When it is necessary to reduce the area of ​​the water collection hopper or to accommodate multiple folding rods 103 and water collection layers 104, the guide block 202 moves upwards. The guide block 202 drives the push block 309 to move upwards, and the compression spring 307 pushes the connecting rod 305 upwards. With the cooperation of the push block 309 and the compression spring 307, the connecting rod 305 moves upwards. The connecting rod 305 drives the lifting frame 301 to move upwards. The lifting frame 301 drives multiple L-shaped transmission rods 302 to move upwards. The multiple L-shaped transmission rods 302 drive multiple fixed shafts 303 to move upwards. The multiple fixed shafts 303 drive multiple folding rods 103 to rotate upwards through multiple transmission slots 304.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, a fixing sleeve 105 is fixedly provided on the top of the stepped main body 101, a filter screen 106 is fixedly provided in a plurality of mounting holes on the side wall of the fixing sleeve 105, a top cover 107 is fixedly provided on the top of the fixing sleeve 105, a connecting frame 112 is fixedly provided on the top of the lifting frame 301, and a sealing sleeve 113 is fixedly provided on the connecting frame 112. The sealing sleeve 113 is located outside the fixing sleeve 105 and is coaxially arranged with the fixing sleeve 105.

[0027] In this embodiment of the invention, rainwater collected in the water collection hopper is filtered by the filter screen 106 and then enters the pipe 108, thereby preventing external solid impurities from affecting the rainwater acidity and alkalinity detection. When the lifting frame 301 moves downward, making the water collection hopper an inverted cone shape, the lifting frame 301 drives the connecting frame 112 to move downward, and the connecting frame 112 drives the sealing sleeve 113 to move downward, thereby making the sealing sleeve 113 cover the fixing sleeve 105, preventing external rainwater from entering the pipe 108 through the filter screen 106 on the fixing sleeve 105. When the acidity and alkalinity detection sensor 111 detects the detection chamber 109, it prevents external rainwater from continuously entering the detection chamber 109, thereby improving the accuracy of rainwater acidity and alkalinity detection.

[0028] like Figure 1 , Figure 2 and Figure 7 As shown, in a preferred embodiment of the present invention, a rinsing assembly 4 is provided on the stepped main body 101. The rinsing assembly 4 includes an annular water tank 401 fixed on the stepped main body 101. A water pump 402 is fixed on the top of the annular water tank 401. The input end of the water pump 402 extends into the annular water tank 401, and the output end of the annular water tank 401 extends into the detection chamber 109 through a connecting water pipe 403.

[0029] In this embodiment of the invention, after the rainwater pH test is completed, or when multiple folding rods 103 and multiple water collection layers 104 are stored, the water pump 402 pumps the cleaning fluid in the annular water tank 401 into the detection chamber 109. The cleaning fluid enters the water collection hopper through the detection chamber 109 and the pipe 108, thereby cleaning the detection chamber 109, the pipe 108 and the water collection hopper. This prevents rainwater residue in the detection chamber 109, the pipe 108 and the water collection hopper from affecting the accuracy of the next test, and also prevents rainwater from corroding the detection chamber 109, the pipe 108 and the water collection hopper. When cleaning the water collection hopper, the folding rods 103 can be rotated to a vertical position, thereby reducing the capacity of the water collection hopper and reducing the consumption of cleaning fluid.

[0030] like Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, in a preferred embodiment of the present invention, a water sample storage mechanism 5 is provided on the stepped main body 101. The water sample storage mechanism 5 includes an annular track 501 fixed inside the stepped main body 101. An annular workstation frame 502 is rotatably connected inside the annular track 501. A rotating component 6 for driving the annular workstation frame 502 to rotate is provided at the bottom of the stepped main body 101. A plurality of storage slots 503 are evenly arranged in a ring on the top of the annular workstation frame 502. Each of the 03 chambers is equipped with a collection bucket. A guide groove 506 is located at the bottom of the detection chamber 109. A water inlet housing 507 is slidably connected within the guide groove 506. Multiple water inlet holes 508 are provided on the side wall of the water inlet housing 507. A second compression spring 509 is connected to the top of the guide groove 506, with its end connected to the water inlet housing 507. A water inlet notch is located at the top of the annular track 501, below and connected to the guide groove 506. An upper lifting assembly is located below the annular workstation frame 502 within the stepped main body 101. This upper lifting assembly is positioned directly below the guide groove 506 and is used to push the collection bucket upwards. A sealing cap is threaded to the top of the annular track 501; removing the sealing cap allows for easy access to the collection bucket within the storage slot 503. The rotating assembly 6 includes an internal toothed ring 601 fixed to the bottom of the annular workstation frame 502 and a second motor 602 fixed to the bottom of the stepped main body 101. The rotating end of the second machine 602 extends into the stepped main body 101 and is fixedly provided with a gear 603, which meshes with the internal gear ring 601; the upper top assembly includes a telescopic member 505 fixedly provided in the stepped main body 101, the telescopic end of the telescopic member 505 is connected to a top block 504, the top block 504 is located directly below the guide groove 506 and below the annular track 501, and both the annular track 501 and the annular workstation frame 502 are provided with clearance grooves for avoiding the top block 504.

[0031] In this embodiment of the invention, when abnormal data is encountered during rainwater pH testing, and rainwater samples need to be retained, the telescopic member 505 extends, causing the top block 504 to move upward. The top block 504 passes through the clearance groove on the annular track 501 and the annular workstation frame 502 and pushes the collection bucket upward. The collection bucket moves upward, passes through the water inlet at the top of the annular track 501, and contacts the water inlet housing 507. The collection bucket overcomes the elastic force of the compression spring 509 and pushes the water inlet housing 507 upward until it reaches the side wall of the water inlet housing 507. The water inlet 508 enters the detection chamber 109. Rainwater in the detection chamber 109 enters the collection bucket through the water inlet 508. Excess rainwater is discharged through the drain pipe at the bottom of the detection chamber 109. Then the telescopic component 505 resets. The collection bucket falls into the storage slot 503 of the annular workstation frame 502 by its own weight. The motor 602 drives the gear 603 to rotate. The gear 603 drives the internal gear ring 601 to rotate. The internal gear ring 601 drives the annular workstation frame 502 to rotate. The annular workstation frame 502 drives multiple storage slots 503 and collection buckets to switch workstations to facilitate the retention of rainwater in the next cycle.
