Description

Technical Field

[0001] This utility model relates to the field of soil and groundwater remediation technology, and in particular to a groundwater level gauge for industrial parks. Background Technology

[0002] In the operation and management of industrial parks, the stability of the groundwater system is directly related to water resource security, environmental risk prevention and control, and infrastructure safety. In the field of soil and groundwater pollution remediation and control in industrial parks, groundwater level data is the core basis for judging groundwater flow direction, defining the scope of pollution diffusion, and optimizing the operating parameters of remediation equipment. A groundwater level gauge for industrial parks is a special monitoring device developed for the specific needs of this scenario. It is suitable for complex environments with dense equipment, road obstructions, and inconvenient external power supply, and realizes convenient mobile measurement and long-term automatic monitoring of groundwater level.

[0003] Early groundwater level measurements in industrial parks relied on manual inspections or wired level gauges, which was not only time-consuming and labor-intensive, but also limited by site constraints in the complex production environment of industrial parks, resulting in poor data timeliness and difficulty in meeting dynamic monitoring needs. To address these issues, automated monitoring equipment was used to automatically collect data, providing data support for the remediation and control of soil and groundwater pollution in industrial parks. However, in actual use, groundwater level data changes dynamically at different times of the day due to remediation measures during the remediation process in industrial parks. The delayed parameter feedback makes it difficult to support timely adjustments to remediation strategies, leading to low remediation efficiency or waste of resources. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a groundwater level gauge for an industrial park, including a base 1, which is a bearing platform. A bracket 4 is fixedly connected to the top of the base 1, which provides installation support. A detection mechanism 2 is provided on the inner side of the bracket 4, and an adjustment mechanism 3 is provided on the top of the bracket 4.

[0038] The bracket 4 is internally connected to a rotating shaft 201, which transmits the rotational power of the crank 206 to drive the reel 202 to wind up and unwind the cable 203. The reel 202 is fixedly connected to the outer wall of the rotating shaft 201. The reel 202 achieves orderly winding and unwinding of the cable 203 through the rotation of the rotating shaft 201, preventing the cable 203 from getting tangled and ensuring the pressure sensor 204 can be smoothly inserted or removed. The cable 203 is provided on the outer wall of the reel 202, connecting the pressure sensor 204 and the reel 202, transmitting an electrical signal. One end of the cable 203 is fixedly connected to a pressure sensor. Device 204, pressure sensor 204 converts water pressure into an electrical signal to calculate the thickness of the water layer above the sensor. A scale line 205 is set on one side of the outer wall of cable 203. The scale line 205 is engraved on the outer wall of cable 203 to intuitively display the length of cable 203 when it is lowered, reducing the error of manual reading. A crank 206 is rotatably connected to the right end of bracket 4. The left end of crank 206 passes through the right end of bracket 4 and is fixedly connected to the right end of rotating shaft 201. Crank 206 provides effortless rotation power for rotating shaft 201. A locking component 207 is set on the right side of the outer wall of rotating shaft 201.

[0039] The locking assembly 207 includes a spline 2071, the inner wall of which is fixedly connected to the right side of the outer wall of the rotating shaft 201. A spring 2072 is fixedly connected to the right side of the inner wall of the bracket 4. The spring 2072 provides a reset force for the keyway ring 2073, realizing the automatic engagement of the keyway ring 2073 and the spline 2071. The left end of the spring 2072 is fixedly connected to the keyway ring 2073. The spline 2071 engages with the keyway ring 2073, and the limiting action of the keyway ring 2073 locks the rotating shaft 201, preventing the wire from being locked. The cable 203 is offset in length. A handle 2074 is fixedly connected to the outer wall of the keyway ring 2073. The handle 2074 provides an operating force point for the keyway ring 2073. A buckle 2075 is rotatably connected to the top right side of the handle 2074. A retaining ring 2076 is fixedly connected to the upper right side of the inner wall of the bracket 4. The buckle 2075 and the retaining ring 2076 engage with each other. The retaining ring 2076 provides a base for engaging the buckle 2075 and temporarily fixes the keyway ring 2073 to ensure the stable rotation of the shaft 201 when the cable 203 is lowered.

[0040] A limiting platform 5 is fixedly connected to the lower right side of the inner wall of the bracket 4. The bottom of the outer wall of the keyway ring 2073 is slidably connected to the inner wall of the limiting platform 5. The limiting platform 5 provides sliding guidance and rotation restriction for the keyway ring 2073, ensuring that the keyway ring 2073 and the spline 2071 are precisely engaged. A movable arm 6 is fixedly connected to the upper right side of the rear side of the bracket 4. The movable arm 6 provides angle adjustment support for the display panel 7. One end of the movable arm 6 is rotatably connected to the display panel 7. The display panel 7 automatically calculates and displays the water level value, records and transmits data remotely at regular intervals, realizing the record without manual reading and meeting the needs of long-term monitoring.

[0041] Specifically, before lowering the cable 203 and pressure sensor 204, the handle 2074 must be pulled to cause the keyway ring 2073 to slide to the right along the limiting platform 5 and compress the spring 2072. When the keyway ring 2073 disengages from the spline 2071 on the rotating shaft 201, the rotation limit of the rotating shaft 201 is released. Then, the buckle 2075 is rotated to engage with the retaining ring 2076, thereby fixing the position of the keyway ring 2073. Finally, the crank handle 206 is turned to drive the rotating shaft 201. Synchronously rotating with the reel 202, the cable 203 is slowly lowered. The length of the lowered cable 203 can be visually determined by the scale lines 205 on its outer wall. During lowering, the cable 203 is ensured to be longer than the groundwater depth in the area but shorter than the well depth, so that the pressure sensor 204 at the end is completely submerged. Simultaneously, the cable 203 is kept vertical due to gravity to prevent damage from contact with the bottom. When the cable 203 reaches the target position, the locking mechanism is engaged. When 2075 separates from the retaining ring 2076, the spring 2072 resets and pushes the keyway ring 2073 to move to the left along the limiting platform 5, so that it re-engages with the spline 2071. Since the limiting platform 5 restricts the rotation of the keyway ring 2073, the engagement between the keyway ring 2073 and the spline 2071 can firmly fix the rotating shaft 201, preventing the cable 203 from shifting in length due to its own weight or water flow impact, and ensuring the stability of the cable 203 length. Subsequently, the pressure sensor 204 measures the change in upper water pressure, converts the water pressure signal into an electrical signal, and then calculates the thickness of the water layer above the pressure sensor 204. The relevant data is transmitted to the display board 7 supported by the movable arm 6 on the rear side of the bracket 4. The display board 7 automatically calculates the difference between the length of the cable 203 and the thickness of the water layer above the pressure sensor 204, and displays the groundwater level value in real time without manual conversion. At the same time, the display board 7 records the water level data at regular intervals and transmits it remotely, thereby meeting the needs of not requiring manual reading of records and continuous monitoring of water level changes.

[0042] Reference Figure 1 , Figure 3 and Figure 5The adjustment mechanism 3 includes two support blocks 301, which provide mounting support for the connecting block 304 and the support rod 305. The bottoms of the two support blocks 301 are fixedly connected to the top left and right sides of the bracket 4, respectively. Multiple pin holes 302 are provided on the left and right sides of each support block 301, providing different locking positions for the pins 303. The front ends of each support block 301 are rotatably connected to the connecting block 304, and the interior of each connecting block 304 is rotatably connected to the support rod 305. The support rod 305 provides tilt support for the photovoltaic panel frame 307, ensuring the structural stability of the frame at different angles. One end of each support rod 305 is fixedly connected to... A sleeve 306 is attached, and a pin 303 is provided on one side of each of the two support blocks 301. The pin 303 can be inserted and removed through the pin hole 302 of the support block 301 and the sleeve 306. The outer wall of the two pins 303 is slidably connected to the inner wall of the corresponding sleeve 306 and the pin hole 302. The sleeve 306 is embedded in the support block 301 and cooperates with the pin 303 and the pin hole 302 to lock the position of the support rod 305 and fix the tilt angle of the photovoltaic panel frame 307. The top of the two connecting blocks 304 is fixedly connected to the same photovoltaic panel frame 307. The photovoltaic panel frame 307 carries the main photovoltaic panel. Folding components 308 are provided on the left and right sides of the photovoltaic panel frame 307.

[0043] The folding assembly 308 includes two connecting rods 3083. One end of each connecting rod 3083 is rotatably connected to the rear left and right ends of the photovoltaic panel frame 1 307. Photovoltaic panel frame 2 3081 is provided on both the front and rear sides of the photovoltaic panel frame 1 307. The photovoltaic panel frame 2 3081 is equipped with auxiliary photovoltaic panels. When unfolded, it expands the photovoltaic panel area and increases the solar energy absorption. The other end of each connecting rod 3083 is rotatably connected to the front left and right ends of the corresponding photovoltaic panel frame 2 3081. Hinges 3082 are fixedly connected to the left and right sides of the top rear end of the front photovoltaic panel frame 2 3081. The hinges 3082 enable the front frame 2 to be flipped and connected to the frame 1, ensuring that the front frame 2 can be unfolded flexibly. The rear photovoltaic panel frame 2 3081 is rotatably connected to the photovoltaic panel frame 1 307 through the hinges 3082. Limiting pieces 3084 are fixedly connected to the front and rear sides of the bottom of the photovoltaic panel frame 1 307. The limiting pieces 3084 limit the unfolding angle of the frame 2, prevent excessive flipping damage, and ensure the stability of the folding assembly 308.

[0044] Specifically, when adjusting the light-receiving angle of the photovoltaic panel, firstly, the photovoltaic panel frame 307 is raised to the desired tilt angle. Then, the support rod 305 is rotated downwards inside the connecting block 304, causing the sleeve 306 at the end of the support rod 305 to embed into the support block 301. Since the support block 301 has multiple pin holes 302 on both sides, with different pin holes 302 corresponding to different tilt angles, the pin 303 is passed through the corresponding pin hole 302 and sleeve 306 to lock the position of the movable end of the support rod 305. Through the cooperation of the pin 303 and different pin holes 302, the photovoltaic panel frame 307 can be fixed at multiple angles. The rear photovoltaic panel frame 3081 is unfolded outward with the connecting rod 3083 as the pivot point. Then, the front photovoltaic panel frame 3081 is flipped upward with the hinge 3082 as the pivot point until the two photovoltaic panel frames 3081 and the photovoltaic panel frame 307 are on the same inclined plane. The limiting piece 3084 at the bottom of the photovoltaic panel frame 307 can limit the unfolding angle of the photovoltaic panel frame 3081 to prevent excessive flipping and structural damage. After unfolding, the area of ​​the photovoltaic panel doubles, which can maximize the absorption of solar energy. The energy is then stored through the battery to ensure stable power generation. At the same time, the folding structure can reduce the floor space occupied when stored.

[0045] Reference Figure 1 , Figure 2 and Figure 6 Two wheel frames 8 are fixedly connected to both the left and right sides of the base 1. The wheel frames 8 provide rotational support for the rollers 9, achieving a stable connection between the rollers 9 and the base 1. Rollers 9 are rotatably connected to the inner sides of multiple wheel frames 8. The rollers 9 contact the ground, converting the sliding friction between the equipment and the ground into rolling friction, allowing the staff to push the equipment and quickly switch between different monitoring wellheads in the park. Studs 10 are fixedly connected to the bottom of the base 1 around all four sides. The studs 10 provide a threaded connection base for the threaded cylinder 11, enabling the vertical adjustment of the threaded cylinder 11. The outer walls of the studs 10 are all threaded. There is a threaded cylinder 11, which adjusts up and down to fit uneven ground through the action of the thread, ensuring that the base 1 is level; the outer walls of multiple threaded cylinders 11 are treated with anti-slip treatment, and friction pads 12 are fixedly connected to the bottom of multiple threaded cylinders 11. The friction pads 12 increase the friction with the ground, thereby improving the stability of the equipment when it is fixed; a guardrail 13 is fixedly connected to the front end of the bracket 4. The guardrail 13 guides and limits the cable 203 during winding and unwinding, preventing the cable 203 from deviating from the vertical direction. The position of the rear wall of the guardrail 13 matches the position of the front side of the outer wall of the cable 203.

[0046] Specifically, when it is necessary to change the monitoring wellhead within the production area, first rotate the threaded cylinder 11 on the outer wall of the stud 10. The anti-slip treatment on the outer wall facilitates manual operation. Through the threaded transmission, the threaded cylinder 11 moves upward along the stud 10 until the bottom of the threaded cylinder 11 is higher than the bottom of the roller 9. At this time, the roller 9 contacts the ground, and the equipment can be pushed by the roller 9 to quickly complete the switching of monitoring points. After the equipment moves to the target monitoring wellhead, rotate the threaded cylinder 11 in the opposite direction to move it downward along the stud 10 until the friction pad 12 at the bottom of the threaded cylinder 11 is in close contact with the ground, and the height of the threaded cylinder 11 is lower than the bottom of the roller 9. At this time, the roller 9 is lifted off the ground, and the equipment is fixed to the ground by the support of the four threaded cylinders 11. The friction pad 12 increases the friction with the ground. At the same time, the adjustment method of the threaded connection can adapt to the wellhead ground with different flatness, ensuring that the base 1 is horizontal. During the lowering or retrieval of the cable 203, the guardrail 13 can guide and limit the cable 203 to prevent the cable 203 from deviating from the vertical direction due to the shaking during operation.

[0047] Working principle: Before lowering the cable 203 and pressure sensor 204, pull the handle 2074 to slide the keyway ring 2073 to the right along the limiting platform 5 and compress the spring 2072. The keyway ring 2073 disengages from the spline 2071 on the rotating shaft 201, releasing the rotation limit of the rotating shaft 201. Then, rotate the buckle 2075 to engage with the retaining ring 2076, keeping the position of the keyway ring 2073 fixed. Next, turn the crank handle 206 to drive the rotating shaft 201 and the reel 202 to rotate synchronously. The cable 203 is slowly lowered as the reel 202 rotates. The scale line 205 on the outer wall of the cable 203 can be used to visually read the length of the lowered cable 203. During the lowering process, ensure that the length of the cable 203 is greater than the groundwater depth of the area but less than the well depth, so that the pressure sensor 204 at the end is completely submerged in water, and the cable 203 remains vertical due to gravity. To prevent damage from bottoming out, when the cable 203 is lowered to the target position, the buckle 2075 separates from the retaining ring 2076, and the spring 2072 resets and pushes the keyway ring 2073 to move to the left along the limiting platform 5, re-engaging with the spline 2071. Because the limiting platform 5 restricts the rotation of the keyway ring 2073, the engagement with the spline 2071 can fix the rotating shaft 201, preventing the cable 203 from shifting in length due to its own weight or water flow impact, ensuring that the length of the cable 203 remains stable. Subsequently, the pressure sensor 204 measures the change in the upper water pressure, converts the water pressure signal into an electrical signal, calculates the thickness of the water layer above the pressure sensor 204, and transmits the data to the display panel 7 supported by the movable arm 6 on the rear side of the bracket 4. The display panel 7 automatically calculates the difference between the length of the cable 203 and the thickness of the water layer above the pressure sensor 204, and displays the groundwater level value in real time.

[0048] Furthermore, when it is necessary to adjust the angle of sunlight received by the photovoltaic panel, first lift the photovoltaic panel frame 307 upwards to the required tilt angle, then rotate the support rod 305 downwards inside the connecting block 304, so that the sleeve 306 at the end of the support rod 305 is embedded inside the support block 301. Since the support block 301 has multiple pin holes 302 on its left and right sides, and different pin holes 302 correspond to different tilt angles, at this time, passing the pin 303 through the corresponding pin hole 302 and sleeve 306 can lock the position of the movable end of the support rod 305. Through the cooperation of the pin 303 and different pin holes 302, the photovoltaic panel frame 307 is adjusted. With multi-angle fixing, the rear photovoltaic panel frame 2 3081 is unfolded outward with the connecting rod 3083 as the rotation fulcrum. Then, the front photovoltaic panel frame 2 3081 is flipped upward with the hinge 3082 as the fulcrum until the two photovoltaic panel frames 2 3081 and photovoltaic panel frame 1 307 are on the same inclined plane. The limiting piece 3084 at the bottom of photovoltaic panel frame 1 307 can limit the unfolding angle of photovoltaic panel frame 2 3081 to avoid excessive flipping and damage to the structure. After unfolding, the area of ​​the photovoltaic panel doubles, maximizing the absorption of solar energy and then storing it through the battery to provide a stable power generation guarantee. At the same time, the folding structure reduces the floor space occupied when stored.
