Technical Field

[0001] This utility model belongs to the field of wastewater detection and relates to a rapid detection device for groundwater pollution. Background Technology

[0002] Wastewater testing involves the qualitative identification, concentration measurement, and distribution analysis of pollutants in water bodies. Groundwater, as a crucial global source of drinking water and ecological water, is buried in underground rock strata or soil pores; once polluted, it poses a long-term threat to human health and the ecological environment.

A water pumping chamber is connected to the bottom of the water pumping chamber. A water-slinging ring is fixedly connected to the bottom of the water pumping chamber.

[0004] The existing technology has the following technical defects:

[0005] However, the aforementioned winding assembly can only complete cable retrieval independently and lacks a synchronous cable-leveling structure, which causes the cables to accumulate and tangle randomly on the drum. This not only causes wear on the outer layer of the cable and breakage of internal wires or water pipes, affecting the transmission of detection signals or sample collection, but also hinders the smooth lowering and retrieval of the detection head, and may even cause interruptions in the detection process. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a rapid detection device for groundwater pollution.

[0007] The groundwater pollution rapid detection device of this utility model includes a cable sleeve and a sewage detector. The bottom of the sewage detector is connected to a loading shell, and the loading shell is provided with a winding unit and a wire leveling unit adapted to the cable sleeve.

[0008] The winding unit includes a servo motor fixed inside the loading housing, a drum fixedly connected to the servo motor, the drum being rotatably connected to the loading housing via a fixing block, and a pulley adapted to the leveling unit being fixedly connected to one end of the drum.

[0009] The uniform line unit includes a reciprocating slide rod rotatably connected inside the loading housing. A slider is slidably connected to the reciprocating slide rod. A guide ring corresponding to the cable sleeve is connected to the slider. A pin is provided at the bottom of the guide ring that matches the groove of the reciprocating slide rod. A second pulley corresponding to a first pulley is provided at one end of the reciprocating slide rod. The first pulley and the second pulley are connected by a belt.

[0010] The uniform line unit also includes a second fixed block and a third fixed block disposed inside the loading housing. A reciprocating slide rod is rotatably connected to the second fixed block and the third fixed block, and a slide rail adapted to the slider is connected between the second fixed block and the third fixed block.

[0011] Two fixing plates are fixedly installed inside the loading housing. Each fixing plate is fixedly connected to a fixed sliding rod that is fixedly connected to the loading housing. The two fixed sliding rods are respectively slidably connected to a bottom block corresponding to fixing block two and fixing block three. A spring is sleeved on the fixed sliding rod between the bottom block and the fixing plate.

[0012] A detection head is fixedly installed at one end of the cable sleeve, and a guide wheel adapted to the cable sleeve is provided on the loading housing. A through groove is opened on the lower surface of the loading housing.

[0013] The loading housing is equipped with guide wheels for directional buffering and clamping of the cable sleeve.

[0014] The outer side of the loading housing is rotatably connected to a pulley that is fixedly connected to a belt pulley.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses the servo motor of the winding unit as the core power source, which can simultaneously achieve dual drive during operation. It directly drives the drum to rotate, completing the efficient winding of the cable sleeve. Indirectly, it drives the pulley to rotate, which can drive the slider to make stable reciprocating motion along the reciprocating slide bar. This allows the cable sleeve to be evenly wound on the surface of the drum after passing through the guide ring. This solves the problem of cable accumulation and knotting in traditional devices, effectively protects the integrity of the internal wires and water pipes of the cable, and ensures the stability of detection signals and sample transmission.

[0033] Example 1

[0034] like Figures 1 to 7As shown, the rapid groundwater pollution detection device of this utility model includes a cable sleeve 7 and a wastewater detector 1. The wastewater detector 1 is connected to a loading housing 2 at its bottom. Inside the loading housing 2 are a winding unit 3 and a wire leveling unit 4 adapted to the cable sleeve 7. The winding unit 3 includes a servo motor 301 fixed inside the loading housing 2. A drum 303 is fixedly connected to the servo motor 301 and rotatably connected to the drum 303 within the loading housing 2 via a fixing block 302. One end of the drum 303 is fixedly connected to a pulley 304 adapted to the wire leveling unit 4. The wire leveling unit 4 includes a reciprocating slide rod 407 rotatably connected inside the loading housing 2. A slider 408 is slidably connected to the reciprocating slide rod 407. A guide ring 409 corresponding to the cable sleeve 7 is connected to the slider 408. A pin 410 adapted to the groove of the reciprocating slide rod 407 is provided at the bottom of the guide ring 409. One end of the reciprocating slide bar 407 is equipped with a second pulley 406 corresponding to the first pulley 304. The first pulley 304 and the second pulley 406 are connected by a belt 411. When the first pulley 304 rotates, it drives the second pulley 406 to rotate through the tensioned belt 411. The second pulley 406 is rotatably connected between two fixed blocks 405, thereby driving the first pulley 304 to rotate between the fixed blocks 404 and 405. When the servo motor 301 drives the drum 303 to wind up the cable sleeve 7, the first pulley 304 drives the second pulley 406 to rotate through the belt 411, thereby driving the reciprocating slide bar 407 to rotate. This causes the guide ring 409 to reciprocate through the slider 408 and the ejector pin 410, thereby achieving uniform winding of the cable.

[0035] The uniform line unit 4 also includes a second fixed block 404 and a third fixed block 405 disposed in the loading housing 2. A reciprocating slide rod 407 is rotatably connected to the second fixed block 404 and the third fixed block 405. A slide rail adapted to the slider 408 is connected between the second fixed block 404 and the third fixed block 405.

[0036] Two fixing plates 401 are fixedly installed inside the loading housing 2. Each fixing plate 401 is fixedly connected to a fixed sliding rod 402 that is fixedly connected to the loading housing 2. Each fixed sliding rod 402 is slidably connected to a bottom block 412 that corresponds to the second fixing block 404 and the third fixing block 405. A spring 403 is sleeved on the fixed sliding rod 402 between the bottom block 412 and the fixing plate 401.

[0037] The cable sleeve 7 is fixedly installed with a detection head 8 at one end. The loading housing 2 is provided with a guide wheel 6 that is compatible with the cable sleeve 7. A through groove 9 is opened on the lower surface of the loading housing 2. The cable sleeve 7 is equipped with wires and water pipes, which have a protective function. The through groove 9 can drain the water inside the loading housing 2. The guide wheel 6 allows the detection head 8 and the cable sleeve 7 to be put into water sampling.

[0038] The loading housing 2 is equipped with guide wheels 5 for directional buffering and clamping of the cable sleeve 7. The guide wheels 5 consists of a sliding shell, a sliding seat, a second spring, and rollers. The second spring is installed inside the sliding shell, the sliding seat is slidably installed inside the sliding shell, and the rollers are rotatably connected in the sliding seat. A total of eight guide wheels 5 are provided, arranged in pairs opposite each other, which can guide and clamp the cable sleeve 7 and prevent the cable sleeve 7 from breaking due to excessive tension.

[0039] The outer side of the loading housing 2 is rotatably connected to a dial wheel 305 which is fixedly connected to a pulley 304. When the servo motor 301 fails, the loading and unloading operations can also be performed through the dial wheel 305.

[0040] Working process or working principle:

[0041] When in use, the cable sleeve 7 is installed on the drum 303, and the dial wheel 305 is rotated to make the pulley 304 and the working end of the servo motor 301 precisely match. It is confirmed that the guide wheel 5 (two pairs opposite each other, including the sliding shell, sliding seat, spring 2, and roller) is in an elastic support state. At the same time, the conductivity and sealing of the wire (signal transmission) and water pipe (sampling) inside the cable sleeve 7 are checked. During testing, the servo motor 301 is activated to rotate in reverse, driving the drum 303 to release the cable sleeve 7. The cable sleeve 7 is clamped and limited by the guide wheel 5 (spring two buffers the tension to prevent wire breakage). The detection head 8 is guided by the guide wheel 6 and lowered into the groundwater. After collecting pollution data, the detection head 8 transmits it in real time to the wastewater detector 1 for processing and display via wires. After the test is completed, the servo motor 301 rotates in the forward direction to enter the winding stage. On one hand, it drives the drum 303 to wind up the cable, and on the other hand, it drives the pulley 304 to rotate. The belt 411 (spring 403 on the bottom block 412 ensures that the belt 411 is taut) drives the pulley 406 to rotate. This causes the reciprocating slide bar 407 to rotate synchronously. The threaded grooves on the surface of the reciprocating slide bar 407, which are connected end to end, cooperate with the pin 410 below the guide ring 409, driving the slider 408 to reciprocate. This allows the cable sleeve 7 to be evenly wound onto the drum 303 via the guide ring 409, preventing accumulation and tangling. During the winding process, the guide wheel 5 continuously uses roller orientation and spring buffering to ensure stable cable recovery. The through groove 9 below the loading housing 2 can drain internal water, preventing moisture from corroding components such as the servo motor 301 and pulley 304. The wires and water pipes inside the cable sleeve 7 maintain signal transmission and sampling functions respectively, ensuring the efficient and stable operation of the entire device.

[0042] This invention uses the servo motor 301 of the winding unit 3 as the core power source. During operation, it can simultaneously achieve dual drive, directly driving the drum 303 to rotate and complete the efficient winding of the cable sleeve 7, and indirectly driving the pulley 304 to rotate, which can drive the slider 408 to make stable reciprocating motion along the reciprocating slide bar 407, so that the cable sleeve 7 is evenly wound on the surface of the drum 303 after passing through the guide ring 409. This solves the problem of cable accumulation and knotting in traditional devices, effectively protects the integrity of the wires and water pipes inside the cable, and ensures the stability of detection signal and sample transmission.

[0043] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
