Description

Technical Field

[0001] The utility model belongs to the field of groundwater prevention and control, and particularly relates to a device for preventing and controlling groundwater pollution. Background Art

[0002] Groundwater refers to the water stored in the rock voids below the ground surface. Narrowly speaking, it refers to the water in the saturated aquifer below the groundwater level. Broadly speaking, it refers to the gravity water with a free water surface above the first impermeable layer below the bottom of the cutting. Groundwater is an important part of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial and mining, and cities. At the same time, groundwater also plays a very important role in coordinating the natural environment.

[0003] In the prior art, a Chinese patent with the publication number CN210905174U discloses a device for preventing and treating groundwater pollution. When the device is in use, it can be quickly and fixedly installed through the support plate and the installation fixing holes. The sundries in the groundwater can be intercepted through the filter net. The intercepted sundries fall into the sewage collection frame of the sewage collection device. The clamping plates fixedly installed at the middle parts of both ends of the sewage collection frame are pulled by the lifting ropes. The clamping plates slide in the sliding chutes to lift the sewage collection frame. Drainage holes are symmetrically opened at both ends of the sewage collection frame. The groundwater inside the sewage collection frame can be discharged through the filter net and the drainage holes. Therefore, it is more labor-saving to drag the sewage collection frame upward through the lifting ropes. The sundries in the sewage collection frame are taken out through the sewage collection slot opened on the support plate. Sampling devices are symmetrically installed on both sides of the support plate. The water delivery pipes in the sampling devices penetrate through the fixed outer frame and the filter pipes are located below the fixed outer frame. The upper ends of the water delivery pipes are connected to an external water suction device. After the larger sundries contained in the groundwater are filtered by the filter pipes, the groundwater can be taken out conveniently and quickly, so as to facilitate the detection of its internal components.

[0004] However, for an existing device for preventing and treating groundwater pollution, the sewage collection frame is fixed to the clamping plates, so that the sewage collection frame can only rise to the lower part of the sewage collection slot. When taking out the sundries in the sewage collection frame, the sundries in the sewage collection frame can only be taken out little by little from the sewage collection slot. The process of taking out the sundries is relatively slow and cumbersome. Moreover, during the process of taking out the sundries in the sewage collection frame, if the sewage collection frame is collided or shaken, it is easy to cause relatively fine sundries to fall back into the groundwater from the filter net and the drainage holes, affecting the water quality of the groundwater. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for preventing and controlling groundwater pollution, which can quickly and conveniently take out the filtered sundries and reduce the amount of sundries falling.

[0006] The described groundwater pollution prevention and control device includes a fixed outer frame with openings at the front and back. A support plate is horizontally fixed at the top of the fixed outer frame. A number of fixed insertion rods are inserted through the support plate.

A cleaning component for cleaning the sundries attached to the filter net is arranged on the sewage collection tank body. A sampling component for extracting samples is arranged on the fixed outer frame.

[0007] Further, the locking component includes a number of fastening screws. A number of fixed sleeves are vertically fixed inside the sewage collection tank body. A number of through holes that communicate up and down are provided at the bottom of the sewage collection tank body corresponding to all the fixed sleeves. A number of threaded holes that are in threaded cooperation with the fastening screws are provided on the positioning plate corresponding to all the through holes. The threaded ends of all the fastening screws are respectively inserted through all the fixed sleeves, and the threaded ends are respectively matched with the corresponding threaded holes.

[0008] Further, the lifting component includes two connecting blocks. The two connecting blocks are respectively vertically fixed at the left and right ends of the positioning plate. Sliding grooves for the two connecting blocks to slide are respectively provided on the left and right inner side walls of the fixed outer frame. A lifting rope is connected to the connecting block. One end of the lifting rope passes through the support plate and is connected to an external winding device.

[0009] Further, the cleaning component includes two support rods. The two support rods are vertically fixed at the top of the sewage collection tank body at left and right intervals. A cleaning brush for cleaning the filter net is horizontally fixed between the two support rods.

[0010] Further, a guide plate for guiding sundries to fall into the sewage collection tank body is obliquely fixed at the top of the sewage collection tank body.

[0011] Further, the sampling component includes a number of filter sleeves. A number of water delivery pipes are inserted through the support plate.

[0013] Further, a number of lifting handles that are convenient for lifting are fixed at the top of the sewage collection tank body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Drive the sewage collection tank body to move upward through the lifting component and make its top pass through the sewage extraction port. Then, release the locking of the positioning plate by the locking component. The staff holds the two handles on the left and right to transfer the sewage collection tank body, and quickly and conveniently take out the entire sewage collection tank body, avoiding excessive sundries from falling back into the groundwater and affecting the water quality of the groundwater. When putting a new sewage collection tank body into the fixed outer frame from the sewage extraction port, snap the positioning plate into the installation groove, and then lock the positioning plate snapped into the installation groove through the locking component to prevent the positioning plate from disengaging from the installation groove, making the sewage collection tank body more stable. Then, lower the newly installed sewage collection tank body to the inner bottom of the fixed outer frame through the lifting component. When the sewage collection tank body moves, the bristles on the cleaning brush will brush off the sundries on the filter screen. The fallen sundries will contact the guide plate and move along the guide plate towards the sewage collection tank body, so that all the cleaned fallen sundries are collected in the sewage collection tank body, avoiding excessive attached sundries from affecting the use of the filter screen.

[0022] The present utility model will be further described below with reference to the accompanying drawings through specific embodiments, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.

[0023] Embodiment 1

[0024] A groundwater pollution prevention and control device described in this embodiment includes a fixed outer frame 4 with openings at the front and rear. A support plate 1 is horizontally fixed at the top of the fixed outer frame 4. A number of fixed insertion rods 3 are inserted through the support plate 1. In this embodiment, there are four groups of fixed insertion rods 3, which are respectively located at the four corners of the support plate 1. The fixed outer frame 4 is inserted into the ground so that the support plate 1 fits with the ground, and then the support plate 1 and the fixed outer frame 4 are fixed by the four fixed insertion rods 3, thus preventing the support plate 1 or the fixed outer frame 4 from loosening.

[0025] A filter screen 13 is vertically fixed inside the fixed outer frame 4. A sewage collection trough 6 with an upward opening is horizontally arranged inside the fixed outer frame 4. The rear side wall of the sewage collection trough 6 is attached to the filter screen 13, so that the sundries falling on the filter screen 13 can fall into the sewage collection trough 6, and the sundries are collected through the sewage collection trough 6.

[0026] A sewage extraction port that communicates up and down for the sewage collection trough 6 to pass through is opened at the top of the support plate 1 and the fixed outer frame 4. After the sewage collection trough 6 is filled with sundries, the sewage collection trough 6 is moved upward so that the top of the sewage collection trough 6 passes through the sewage extraction port of the support plate 1 and the fixed outer frame 4, enabling the whole sewage collection trough 6 to be taken out for replacement, and the sundries can be taken out more conveniently and quickly.

[0027] An installation groove that communicates left and right is opened at the bottom of the sewage collection trough 6. A positioning plate 10 is independently clamped inside the installation groove. The installation groove is located at the center of the bottom of the sewage collection trough 6. When installing the sewage collection trough 6, the positioning plate 10 is clamped into the installation groove to position the sewage collection trough 6, making the sewage collection trough 6 more stable during lifting and lowering movement and preventing the sewage collection trough 6 from moving and affecting its passing through the sewage extraction port.

[0028] Perforations that communicate inside and outside are opened on the front and rear side walls of the sewage collection trough 6. A water filter net 9 is installed inside the perforations. The groundwater inside the sewage collection trough 6 can be discharged through the water filter net 9, making it more labor-saving to drag the sewage collection trough 6 upward through the lifting rope 2.

[0029] A number of lifting handles are fixed at the top of the sewage collection trough 6. One lifting handle is fixed at each of the left and right ends at the top of the sewage collection trough 6. When disassembling and installing the sewage collection trough 6, the staff can hold the left and right two lifting handles to transfer the sewage collection trough 6, making it more convenient and labor-saving for the staff to operate.

[0030] For further explanation, such as Figure 1 、 Figure 2 and Figure 5As shown, preferably, a number of fastening screws 8 are included in this embodiment. A number of fixing sleeves 7 are vertically fixed in the sewage collecting tank body 6. A number of through holes communicating up and down are formed at the bottom of the sewage collecting tank body 6 corresponding to all the fixing sleeves 7. A number of threaded holes threadedly engaged with the fastening screws 8 are formed on the positioning plate 10 corresponding to all the through holes. The threaded ends of all the fastening screws 8 are respectively inserted into all the fixing sleeves 7, and the threaded ends are respectively engaged with the corresponding threaded holes. In this embodiment, there are two fixing sleeves 7. The two fixing sleeves 7 are arranged in alignment at left and right intervals and are respectively attached to the left and right inner side walls of the sewage collecting tank body 6. After the positioning plate 10 is engaged in the installation groove, rotate the fastening screw 8 to make the fastening screw 8 threadedly engaged with the threaded hole on the positioning plate 10, so as to fasten and lock the positioning plate 10 and the sewage collecting tank body 6, prevent the positioning plate 10 from disengaging from the installation groove, make the sewage collecting tank body 6 more stable. The tops of the fixing sleeves 7 are flush with the top of the sewage collecting tank body 6, so as to ensure that the sundries in the sewage collecting tank body 6 will not cover the fastening screws 8, facilitating the staff to find the positions of the fastening screws 8. The overall solution constitutes a locking assembly for locking the positioning plate 10 in the installation groove. Of course, the locking assembly can also adopt a screw rod and a nut. The screw rod is vertically fixed on the positioning plate 10. A fixing hole for the threaded rod to pass through is vertically formed on the side wall of the sewage collecting tank body 6. The nut is sleeved on the threaded rod, and the positioning plate 10 is locked in the installation groove by rotating the nut.

[0031] Further description is as follows. As Figure 1 and Figure 5 shown, preferably, two connecting blocks 11 are included in this embodiment. The two connecting blocks 11 are respectively vertically fixed at the left and right ends of the positioning plate 10. Sliding grooves for the two connecting blocks 11 to slide are formed on the left and right inner side walls of the fixed outer frame 4. A lifting rope 2 is connected to the connecting block 11. One end of the lifting rope 2 passes through the support plate 1 and is connected to an external winding device. The external winding device adopts a winch or a crane, etc. When in use, the external winding device pulls the two lifting ropes 2 to make the two connecting blocks 11 respectively move upward along the sliding grooves on the left and right inner side walls of the fixed outer frame 4. The sliding grooves guide the connecting blocks 11 and prevent the connecting blocks 11 from rotating. The two connecting blocks 11 drive the positioning plate 10 to move upward, so that the sewage collecting tank body 6 above the positioning plate 10 moves towards the sewage taking port. When the two connecting blocks 11 are in contact with the bottom of the support plate 1, the top of the sewage collecting tank body 6 will penetrate out of the sewage taking port, facilitating the staff to disassemble, install, take and place the sewage collecting tank body 6. The overall solution constitutes a lifting assembly for lifting the sewage collecting tank body 6. Of course, the lifting assembly can also adopt an electric hoist. A threaded rod is vertically fixed on the right end of the positioning plate 10. A groove for the threaded rod to move is formed on the right inner side wall of the fixed outer frame 4. A hole for the threaded rod to pass through is formed on the support plate 1. The electric hoist is fixed on the top of the support plate 1 and is engaged with the threaded rod. The electric hoist drives the threaded rod to move up and down, so that the positioning plate 10 drives the sewage collecting tank body 6 to lift.

[0032] Further description is as follows. For example Figure 1 , Figure 2 and Figure 5 shown, preferably, this embodiment includes two support rods. The two support rods are vertically fixed at the top of the sewage collection tank body 6 at left and right intervals. A cleaning brush 5 for cleaning the filter screen 13 is horizontally fixed between the two support rods. A guide plate 12 for guiding sundries to fall into the sewage collection tank body 6 is obliquely fixed at the top of the sewage collection tank body 6; the two support rods are respectively located on the left and right sides of the top of the sewage collection tank body 6. The bristles on the cleaning brush 5 are in contact with the filter screen 13. The guide plate 12 is in the shape of being lower in the front and higher in the rear, and the higher end is in contact with the filter screen 13; during use, when the sewage collection tank body 6 moves up and down, the bristles on the cleaning brush 5 will brush off the sundries on the filter screen 13. The fallen sundries will contact the guide plate 12 and move along the guide plate 12 towards the sewage collection tank body 6, so that all the cleaned fallen sundries are collected in the sewage collection tank body 6, avoiding excessive attached sundries from affecting the use of the filter screen 13; the whole scheme constitutes a cleaning assembly for cleaning the sundries attached to the filter screen 13; of course, the cleaning assembly can also adopt a scraper. The scraper is obliquely fixed at the top of the sewage collection tank body 6 in the shape of being lower in the front and higher in the rear, and the higher end of the scraper abuts against the filter screen 13. When the sewage collection tank body 6 moves, the sundries are scraped off by the scraper and fall into the sewage collection tank body 6. The scraper is made of natural rubber, synthetic rubber or silica gel and other materials, so that the scraper will not damage the filter screen 13 when moving.

[0033] Further description is as follows. For example Figure 2 , Figure 3 and Figure 5As shown, preferably, this embodiment includes a plurality of filter sleeves 15. A plurality of water pipes 14 are inserted through the support plate 1. The lower ends of the water pipes 14 are located inside the fixed outer frame 4. The filter sleeves 15 are respectively sleeved on one ends of all the water pipes 14 located inside the fixed outer frame 4. The water pipes 14 are made of water pipes made of stainless steel, aluminum alloy, copper, cast iron, PVC, PP-R, etc. The water pipes 14 made of these materials are relatively hard, have high pressure resistance, and are not easily bent, so that they are not easily displaced inside the fixed outer frame 4, avoiding affecting the up and down movement of the sewage collection tank body 6. In this embodiment, one is provided at each end of the device. Through holes communicating up and down are provided at the tops of the support plate 1 and the fixed outer frame 4. One ends of two water pipes 14 pass through the through holes and are located inside the fixed outer frame 4. The filter sleeve 15 has a cylindrical structure, and a plurality of small water inlet holes communicating inside and outside are uniformly distributed thereon. The filter sleeve 15 has an interference fit with the lower end of the water pipe 14, so that the filter sleeve 15 is not easily loosened. When in use, it is connected to the upper end of the water pipe 14 through an external water suction device, and after the filter sleeve 15 filters out larger sundries contained in the groundwater, the groundwater can be taken out conveniently and quickly, so as to facilitate the detection of its internal components. After the groundwater sample is extracted, the upper end of the water pipe 14 can be sealed with a sealing plug. This solution as a whole constitutes a sampling component for extracting samples. Of course, a suspension cup can also be used as the sampling component. The suspension cup is located inside the fixed outer frame 4. A pull rod is vertically fixed on the suspension cup. The upper end of the pull rod passes through the support plate 1. When in use, the suspension cup is sunk into the groundwater, and then the suspension cup is pulled upward through the pull rod, so that the suspension cup filled with groundwater is pulled to the sewage extraction port, and the groundwater in the suspension cup is collected.

[0034] During actual use, the fixed outer frame 4 is inserted into the ground so that the support plate 1 fits the ground. Then, the support plate 1 and the fixed outer frame 4 are fixed by four fixed insertion rods 3. During the process of monitoring groundwater, larger debris inside the groundwater can be isolated by the filter net 13. The isolated debris falls into the sewage collection tank 6. When the sewage collection tank 6 is filled with debris, control the external winding device to pull the two lifting ropes 2, so that the two connecting blocks 11 move upward along the chutes on the left and right inner side walls of the fixed outer frame 4 respectively. The chutes guide the connecting blocks 11 and prevent the connecting blocks 11 from rotating. The two connecting blocks 11 drive the positioning plate 10 to move upward, so that the sewage collection tank 6 above the positioning plate 10 moves towards the sewage extraction port. When the sewage collection tank 6 moves, the bristles on the cleaning brush 5 will brush off the debris on the filter net 13. The fallen debris will contact the guide plate 12 and move along the guide plate 12 towards the sewage collection tank 6, so that all the cleaned-up fallen debris is collected in the sewage collection tank 6. Finally, make the top of the sewage collection tank 6 penetrate out of the sewage extraction port, and then rotate the fastening screw 8 to release the lock on the positioning plate 10. The staff holds the left and right handles to transfer the sewage collection tank 6, so as to quickly and conveniently take out the entire sewage collection tank 6, reduce the amount of fallen debris, and avoid excessive debris falling back into the groundwater and affecting the water quality of the groundwater. When putting a new sewage collection tank 6 into the fixed outer frame 4 from the sewage extraction port, snap the positioning plate 10 into the installation groove, and rotate the fastening screw 8 so that the fastening screw 8 is in threaded fit with the threaded hole on the positioning plate 10, thereby firmly locking the positioning plate 10 and the sewage collection tank 6. Lower the newly installed sewage collection tank 6 to the inner bottom of the fixed outer frame 4. When sampling and testing are required, connect the external water suction device to the upper end of the water delivery pipe 14, and after the filter sleeve 15 filters out larger debris contained in the groundwater, the groundwater can be taken out quickly and conveniently, so as to facilitate the detection of its internal components. After the extraction of the groundwater sample is completed, the upper end of the water delivery pipe 14 can be sealed with a sealing plug; this groundwater pollution prevention and control device can quickly and conveniently take out the filtered debris during use, reduce the time consumed in taking out the debris, and reduce the amount of fallen debris, avoiding excessive debris falling back into the groundwater and affecting the water quality of the groundwater.
