[0002] Groundwater is a precious freshwater resource for human beings. However, with the continuous development of the social industrialization process, wastewater discharge, industrial waste residue, agricultural irrigation, landfill leakage, damage to the transportation pipelines and storage tanks of petrochemical raw materials, etc. may cause groundwater pollution, making the already tense water shortage problem more serious. Groundwater remediation has become an environmental issue that has attracted much attention from the public and society. At the same time, after pollutants enter the groundwater, different pollutants will remain in different layers of the groundwater, and then groundwater stratified sampling and stratified remediation devices are needed to treat the groundwater;

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1 , Figure 2 and Figure 3 The groundwater stratified sampling and stratified remediation device shown in FIG. 1 includes:

[0029] A support frame 2 is installed on the top of the sampling well 1, and a servo motor 3 is fixed at the middle position of the top of the support frame 2;

[0030] The output shaft of the servo motor 3 passes through the top wall of the support frame 2 and is connected to the threaded rod 7, and a moving block 8 is movably installed on the surface wall of the threaded rod 7;

[0031] The clamping structure 9 includes a fixing seat 91, a pipe groove 92, a clamping block 93, a first spring 94, a second spring 95, a handle 96 and a moving shaft 97. The fixing seat 91 is fixed to the two side walls of the moving block 8 respectively;

[0032] The fixing seat 91 is provided with a tube groove 92, and the bottom ends of the sampling tube 4 and the repair tube 5 are respectively passed through the tube groove 92;

[0033] Both side walls of the tube groove 92 are elastically connected to the clamping block 93 through the first spring 94;

[0034] A mounting groove is provided on one side wall of the tube groove 92, in which a moving shaft 97 is installed, and one end of the moving shaft 97 is connected to the clamping block 93, and the other end of the moving shaft 97 is elastically connected to the side wall of the mounting groove through a second spring 95;

[0035] A handle 96 is welded and fixed to the top of the moving shaft 97;

[0036] The bottom ends of the sampling tube 4 and the repair tube 5 are respectively passed through the two side walls of the support frame 2 to the inside;

[0037] Specifically, the servo motor 3 is started to drive the threaded rod 7 to rotate, and then the moving block 8 on the surface of the threaded rod 7 cooperates with the thread groove, so that the moving block 8 can move up and down on the surface of the threaded rod 7, thereby synchronously driving the sampling tube 4 and the repair tube 5 to move up and down to reach different stratified parts of the groundwater;

[0038] Furthermore, when the sampling tube 4 and the repair tube 5 are respectively inserted into the tube groove 92 in the fixing seat 91, the handle 96 is first pulled to drive the movable shaft 97 to move in the installation groove, and at the same time, the second spring 95 and the first spring 94 on one side of the tube groove 92 are compressed and deformed, thereby increasing the internal space of the tube groove 92, and the sampling tube 4 and the repair tube 5 can be smoothly and easily inserted into the tube groove 92, respectively. Then, the handle 96 is released, and the second spring 95 and the first spring 94 have a self-resetting function, which drives the clamping block 93 to squeeze and fix the sampling tube 4 and the repair tube 5;

[0039] like Figure 1 and Figure 4 As shown in , a protective structure 6 is provided on both sides of the inner wall of the support frame 2, and the protective structure 6 includes a fixed side plate 61, a rolling wheel 62, a central axis 63 and a groove 64. Two groups of fixed side plates 61 are respectively vertically fixedly connected to the inner wall of the support frame 2, each group of fixed side plates 61 is two pieces, and a central axis 63 is movably installed at the middle position of one end of the two fixed side plates 61, and a rolling wheel 62 is movably sleeved on the surface of the central axis 63, and a groove 64 is opened on the surface of the rolling wheel 62;

[0040] Specifically, when one end of the sampling tube 4 and the repair tube 5 are respectively passed through the two side walls of the support frame 2 to the inside, they will be contacted with the rolling wheel 62 first, and when the sampling tube 4 and the repair tube 5 are raised and lowered in the sampling well 1, the rolling wheel 62 will roll on the central axis 63, thereby replacing the sampling tube 4 and the repair tube 5 directly contacting with the inner wall of the sampling well 1 and causing wear;

[0041] Furthermore, the groove 64 provided in the rolling wheel 62 allows the sampling tube 4 and the repair tube 5 to sink and stabilize when installed on the rolling wheel 62, thereby preventing the sampling tube 4 and the repair tube 5 from sliding off the surface of the rolling wheel 62 when being raised or lowered;

[0042] like Figure 1 and Figure 5 As shown in , the bottom end of the sampling tube 4 is fixedly connected with a sampling head 10, and the sampling head 10 is respectively provided with a suction head and a camera, and the bottom end of the repair tube 5 is fixedly connected with a repair head 11, and the repair head 11 is respectively provided with a feed head and an aeration head;

[0043] Specifically, the sampling tube 4 has an infusion tube and a wire tube, wherein the infusion tube can sample groundwater through an external water pump, and the wire tube is used for wiring, so that the camera can work normally;

[0044] Furthermore, the repair pipe 5 has an infusion pipe and an aeration pipe, through which external medicines can be delivered to the infusion head in the repair head 11 and injected into the appropriate layer of groundwater, and then ozone is delivered to the aeration head through the aeration pipe, and the ozone emitted by the aeration head is used to purify and repair the polluted layers of groundwater;

[0045] Working principle: First, the sampling tube 4 and the repair tube 5 are passed through the side wall of the support frame 2 and the fixing seat 91 in sequence, and the sampling tube 4 and the repair tube 5 are fixed and clamped by the clamping structure 9 respectively;

[0046] Secondly, the support frame 2 is fixedly installed on the appropriate sampling well 1, and the servo motor 3 is started to drive the threaded rod 7 to rotate, and then the moving block 8 is lifted and lowered on the threaded rod 7, thereby driving the sampling head 10 and the repair head 11 installed at the bottom of the sampling tube 4 and the repair tube 5 to move to the appropriate groundwater layer;

[0047] Finally, the groundwater in the groundwater stratification is sampled by using the pump connected to the top of the sampling tube 4, and the sampled water is tested. When the groundwater is found to be polluted, the booster pump at one end of the repair tube 5 transfers the agent to the infusion head through the infusion tube in the repair tube 5, and injects it into the appropriate stratification of the groundwater to purify and repair the contaminated water. Alternatively, an ozone generator is used to transfer ozone through the aeration tube in the repair tube 5 to the aeration head of the repair head 11, and the aeration head emits ozone to purify and repair the contaminated stratification of the groundwater, thereby completing all the work of this device.
