Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically a mobile well-washing device for polluted groundwater. Background Technology

[0002] Pollution refers to the phenomenon where harmful substances enter the natural environment, reaching or exceeding the carrying capacity of the environment, thereby altering the normal state of the environment. Groundwater refers to water that exists in the pores of rocks below the ground surface. In a narrow sense, it refers to water in saturated aquifers below the groundwater level. In the "Hydrogeological Terminology", groundwater refers to gravity water in various forms buried below the surface. Before testing the quality of groundwater, it is necessary to use a well-washing device to pump out the water and return fresh water to ensure that the water sample is representative.

[0003] Currently, most well-washing equipment suffers from defects such as lack of power supply, flow rate control, and well-washing parameters, making it inconvenient to use and affecting subsequent monitoring of groundwater quality. To address these issues, we have developed a portable groundwater contamination well-washing device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile well-washing device for polluted groundwater.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable groundwater well-washing device, comprising a housing, the upper surface of which is hinged with a cover, a battery, a frequency converter, and a flow meter installed on the inner wall of the housing, the frequency converter and the flow meter being electrically connected to the battery via wires, the exterior of the housing being provided with a well-washing device body and two support frames, a winding roller installed between the two support frames, and a handle installed on the winding roller, two connecting blocks fixedly connected to the outer surface of each support frame, the connecting blocks being fixed to the housing with bolts, a protective sleeve fixedly connected to the inner wall of the winding roller, a connecting pipe and a cable fixedly connected to the inner wall of the protective sleeve, the two ends of the connecting pipe being connected to the flow meter and the well-washing device body respectively, the two ends of the cable being electrically connected to the frequency converter and the well-washing device body respectively, and the end of the frequency converter away from the cable being connected to a water outlet pipe.

[0006] Furthermore, each of the support frames has a bearing embedded in its inner wall, and the inner ring of the bearing is fixed to the outer surface of the rotating shaft of the take-up roller. By setting the bearing, the take-up roller can be made more stable when rotating and the resistance of the take-up roller when rotating can be reduced.

[0007] Furthermore, two limiting blocks are fixedly connected to the front of the box, and the well cleaner body is engaged with the limiting blocks. By setting the limiting blocks, the well cleaner body can be easily limited and fixed, thereby forming a whole with each component for subsequent movement.

[0008] Furthermore, the outer surface of the box cover is equipped with a handle to facilitate the movement of the contaminated groundwater well washing device. By setting the handle, the contaminated groundwater well washing device can be moved easily, and the outer surface of the handle can be covered with an anti-slip sleeve to prevent the hand from slipping.

[0009] Furthermore, a placement block is fixedly connected to the inner wall of the box, and several storage tubes for storing groundwater samples are placed on the inner wall of the placement block. Each storage tube is equipped with a cap for sealing the storage tube. A water quality analyzer for water sample testing is placed on the upper surface of the battery. By opening the three-way valve on the outlet pipe, the extracted groundwater can be transported to the storage tube for storage, and the storage tube can be sealed with the cap to prevent groundwater sample leakage. At the same time, the placement block can be used to place the storage tube, and the water quality analyzer can be used to detect the pollution status of the collected groundwater samples.

[0010] Furthermore, a nameplate is fixedly connected to the front of the housing for recording the manufacturer of the groundwater well washing device and its technical data under rated operating conditions. By setting the nameplate, the manufacturer of the groundwater well washing device and its technical data under rated operating conditions can be recorded.

[0011] Furthermore, the variable frequency drive integrates a running speed display screen, a switching power supply, a motor driver, and a speed control knob. The speed control switch can be used to adjust the speed of the motor inside the water pump, thereby controlling the water pumping of the well washing machine. The running speed display screen uses a five-digit LED digital tube, which can clearly and accurately display the motor speed.

[0012] Compared with existing technologies, this mobile groundwater contaminated well washing device has the following advantages:

[0013] 1.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] As described in the background section, most well-washing equipment currently suffers from defects such as lack of power supply, lack of flow rate control, and lack of well-washing parameters, which makes the use of well-washing equipment inconvenient and affects subsequent monitoring of groundwater quality. Therefore, this embodiment provides a mobile well-washing device for contaminated groundwater.

[0024] See Figures 1 to 6This embodiment proposes a portable groundwater well washing device, including a box 1. The upper surface of the box 1 is hinged with a box cover 2. The inner wall of the box 1 is equipped with a storage battery 3, a frequency converter 4 and a flow meter 5. The frequency converter 4 and the flow meter 5 are electrically connected to the storage battery 3 through wires.

[0025] The box body 1 can be closed by the box cover 2, and the fastener connecting the box body 1 and the box cover 2 can be set with reference to the toolbox lock in the prior art. The variable frequency speed controller 4 and the flow meter 5 can be powered by the storage battery 3, and a charging interface for charging the storage battery 3 can be installed on the outer surface of the box body 1.

[0026] The front of the housing 1 is fixedly connected to a nameplate 10 for recording the manufacturer of the groundwater well washing device and its technical data under rated working conditions. By setting the nameplate 10, the manufacturer of the groundwater well washing device and its technical data under rated working conditions can be recorded.

[0027] The outer surface of the box cover 2 is equipped with a handle 18 to facilitate the movement of the contaminated groundwater well washing device. By setting the handle 18, the contaminated groundwater well washing device can be moved easily, and the outer surface of the handle 18 can be covered with an anti-slip sleeve to prevent the hand from slipping.

[0028] The outer side of the housing 1 is provided with a well cleaner body 11 and two support frames 6. A winding roller 7 is installed between the two support frames 6, and a handle 8 is installed on the winding roller 7. Two connecting blocks 9 are fixedly connected to the outer surface of each support frame 6, and the connecting blocks 9 are fixed to the housing 1 by bolts.

[0029] Two support frames 6 can limit and support the winding roller 7, and the winding roller 7 can be rotated. At the same time, bolts can be used to connect the box body 1 and the connecting block 9, thus forming a whole contaminated groundwater well washing device.

[0030] Two limiting blocks 17 are fixedly connected to the front of the housing 1, and the well cleaner body 11 is engaged with the limiting blocks 17. By setting the limiting blocks 17, the well cleaner body 11 can be easily limited and fixed, thereby forming a whole with each component for subsequent movement.

[0031] Each support frame 6 has a bearing 16 embedded in its inner wall, and the inner ring of the bearing 16 is fixed to the outer surface of the shaft of the take-up roller 7. By setting the bearing 16, the take-up roller 7 can be made more stable when rotating and the resistance of the take-up roller 7 when rotating can be reduced.

[0032] A protective sleeve 12 is fixedly connected to the inner wall of the take-up roller 7. A connecting pipe 13 and a cable 14 are fixedly connected to the inner wall of the protective sleeve 12. The two ends of the connecting pipe 13 are connected to the flow meter 5 and the well cleaner body 11, respectively. The two ends of the cable 14 are electrically connected to the frequency converter 4 and the well cleaner body 11, respectively. The end of the frequency converter 4 away from the cable 14 is connected to the water outlet pipe 15.

[0033] The well cleaner body 11 is equipped with a water pump for groundwater extraction. The two ends of the connecting pipe 13 are connected to the output end of the water pump and the flow meter 5, respectively. At the same time, the water pump can be powered by the cable 14 which is electrically connected to the water pump and the frequency converter 4, respectively. A three-way valve is installed on the outlet pipe 15 to control the opening and closing of the corresponding pipeline.

[0034] The inner wall of the housing 1 is fixedly connected to a placement block 19. The inner wall of the placement block 19 is provided with several storage tubes 20 for storing groundwater samples. The inner wall of each storage tube 20 is provided with a cap 21 for sealing the storage tube 20. A water quality detector 22 for water sample testing is placed on the upper surface of the battery 3.

[0035] By opening the three-way valve on the outlet pipe 15, the extracted groundwater can be transported to the storage pipe 20 for storage. The storage pipe 20 can be sealed with the cap 21 to prevent leakage of the groundwater sample. The storage pipe 20 can be placed using the placement block 19, and the pollution status of the collected groundwater sample can be detected using the water quality detector 22.

[0036] Since the speed of a motor is directly proportional to the power supply frequency, the speed of the motor will increase when the power supply frequency increases; conversely, the speed of the motor will decrease when the power supply frequency decreases. The variable frequency drive 4 achieves precise control of the motor speed by changing the power supply frequency.

[0037] The variable frequency speed controller 4 integrates a running speed display, a switching power supply, a motor driver, and a speed control knob. The speed control switch can be used to adjust the speed of the water pump drive motor, thereby controlling the water pumping of the well washing machine. The running speed display uses a five-digit LED digital tube, which can clearly and accurately display the motor speed.

[0038] The components in the accompanying drawings of this utility model are for styling reference only and are not specific dimensional standards. The specific dimensions are determined according to the actual production requirements, and the materials of each component can be replaced accordingly based on actual needs.

[0039] All electrical components in this invention are commercially available, conventional equipment known to those skilled in the art. Models can be selected or customized according to actual needs. The setting method, installation method, and electrical connection method can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0040] Working Principle: When using the portable groundwater contamination well washing device, the washing device body 11 can be placed in the well from which groundwater needs to be extracted. By turning the handle 8, the protective sleeve 12 wound on the take-up roller 7 is gradually loosened, and the washing device body 11 gradually enters the well under the action of gravity. When it reaches the designated position, the power switch on the frequency converter 4 can be pressed to start the water pump drive motor inside the washing device body 11, thereby extracting groundwater. The groundwater flows through the connecting pipe 13 and the flow meter 5 in sequence and finally flows out from the outlet pipe 15, thus ensuring that the groundwater quality extracted from the well is representative, in order to ensure the accuracy of the groundwater pollution detection results. The speed of the water pump drive motor can be adjusted using the speed switch on the frequency converter 4, thereby controlling the water extraction of the washing device. The speed display screen on the variable frequency drive 4 clearly and accurately shows the motor speed. Simultaneously, opening the three-way valve on the outlet pipe 15 allows the extracted groundwater to be transported to the storage pipe 20 for storage. The storage pipe 20 can be sealed with the cap 21 to prevent leakage of the groundwater sample. The storage pipe 20 can be placed using the placement block 19. The water quality analyzer 22 can detect the pollution status of the collected groundwater sample, and the flow meter 5 can monitor the extracted groundwater volume. After use, the pump can be stopped by pressing the power switch on the variable frequency drive 4. Then, the take-up roller 7 can be rotated in the reverse direction using the handle 8 to rewind the protective sleeve 12 and return all components to their original positions. The groundwater well-washing device is designed as a single unit, improving its convenience and practicality for subsequent use and relocation.
