Description

Technical Field

[0001] This invention belongs to the technical field of groundwater monitoring equipment, specifically relating to an integrated prefabricated submersible well. Background Technology

[0002] A submersible well is a water extraction device. There are two different types of groundwater: unconfined water buried above the first stable impermeable layer and confined water buried between the upper and lower stable impermeable layers. A well drilled into the unconfined water is a submersible well. During drilling, in order to ensure the construction progress, the well body of a submersible well is mostly a prefabricated structure, which facilitates the transportation of various components and on-site construction.

[0003] The groundwater is mainly replenished by local atmospheric precipitation and some river and lake water. The groundwater is buried relatively shallow and is greatly affected by the climate, especially precipitation. Groundwater wells can extract water from the groundwater area and facilitate the monitoring of underground groundwater.

[0004] However, since the water source in the groundwater area is greatly affected by precipitation and the water quality changes significantly, impurities tend to accumulate at the bottom and on the inner wall of the well during long-term use. These impurities will be pumped out with the water flow during subsequent water source monitoring, which will have a certain impact on water quality monitoring. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated prefabricated submersible well body that can be assembled during construction and quickly installed upon completion, resulting in a faster construction process. Furthermore, by inserting a sludge extraction component and a cleaning component into the well body, the cleaning component cleans the impurities on the inner wall of the well body and disperses the impurities at the bottom of the well body, while the sludge extraction component extracts the impurities along with the water, thereby achieving the effect of cleaning the well body and ensuring the accuracy of water source monitoring collected by the submersible well body.

[0010] The sludge suction component is designed separately from the assembly well body. The sludge suction component is only inserted into the assembly well body when the assembly well body needs to be cleaned.

[0011] A cleaning component is assembled inside the sludge suction component and is used to clean the inner wall of the assembled well body.

[0012] In a preferred embodiment, the quick-installation mechanism includes a first connector and a second connector.

An external drive device is provided at the top of the first connecting rod and above the first sludge suction pipe. The middle connecting rod is located inside the middle sludge suction pipe, and the last connecting rod is located inside the last sludge suction pipe. Support frames are rotatably connected to the outer sides of the first, middle, and last connecting rods. Several support frames are respectively fixed to the inner walls of the first, middle, and last sludge suction pipes.

[0016] In a preferred embodiment, a cleaning brush is fixed to the outer side of the bottom of the tail section connecting rod. The cleaning brush is located at the bottom of the tail section suction pipe and is rotatably connected to the tail section suction pipe.

[0017] In a preferred embodiment, a lower pipe support assembly is installed on the outer side of the first section of the sludge suction pipe, the extraction pipe, and the middle section of the sludge suction pipe.

[0021] The technical effects achieved by this invention are as follows:

[0022] The quick installation mechanism of this invention allows for the pre-assembly of the well cap, first section pipe, filter mechanism and sedimentation pipe, which facilitates on-site construction and speeds up the construction process.

[0023] The sludge suction component and cleaning component of the present invention can extend into the interior of the assembly well body and start the water pump installed on its top and the external drive device to drive the water flow and the cleaning component to rotate respectively.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0038] Please see the appendix Figure 1 - Figure 5 As shown, the integrated prefabricated submersible well body includes the assembled well body and the sludge suction component 6, with the sludge suction component 6 located inside the assembled well body;

[0039] The assembled well body includes a first section pipe 2, a filter mechanism 3 and a sedimentation pipe 4. The filter mechanism 3 is installed at the bottom of the first section pipe 2, the sedimentation pipe 4 is installed at the bottom of the filter mechanism 3, and a well cap 1 is installed on the top of the first section pipe 2. The well cap 1 is connected to the first section pipe 2, the first section pipe 2 is connected to the filter mechanism 3, and the filter mechanism 3 is connected to the sedimentation pipe 4 through a quick installation mechanism 5.

[0040] The first section of pipe 2, the filter mechanism 3, and the sedimentation pipe 4 are all made of PVC material;

[0041] The sludge suction assembly 6 includes a first sludge suction pipe 61, an extraction pipe 62, a middle sludge suction pipe 63, and a tail sludge suction pipe 64. The extraction pipe 62 is located on one side of the top of the first sludge suction pipe 61 and is used to connect to a water pump. The middle sludge suction pipe 63 is assembled at the bottom of the first sludge suction pipe 61, and the tail sludge suction pipe 64 is assembled at the bottom of the middle sludge suction pipe 63.

[0042] The first section of the sewage suction pipe 61 is connected to the middle section of the sewage suction pipe 63 by a thread, and the middle section of the sewage suction pipe 63 is connected to the tail section of the sewage suction pipe 64 by a thread.

[0043] The sludge suction component 6 is designed to be separate from the assembly well body. The sludge suction component 6 is only inserted into the assembly well body when the assembly well body needs to be cleaned.

[0044] When the assembly well is in normal use, the sludge suction component 6 is detached from the assembly well and stored separately. The sludge suction component 6 is only inserted into the assembly well when the assembly well needs to be cleaned.

[0045] Cleaning component 7 is assembled inside the sludge extraction component 6 and is used to clean the inner wall of the assembly well body.

[0046] As described above, during construction, a small auger is used to rotate downwards to form a hole to the groundwater layer at a predetermined position, forming a well. Then, the sedimentation pipe 4 and the filter mechanism 3 are assembled together, and the first section pipe 2 is assembled together with the filter mechanism 3. Then, they are placed into the well, so that the filter mechanism 3 is located in the groundwater layer. Through the filter mechanism 3, the water in the groundwater layer can seep into the filter mechanism 3, and the water source in the groundwater layer can be drawn out by the extraction equipment, thereby realizing the monitoring of the water source in the groundwater layer.

[0047] In the above, the number of first pipe sections 2 required to assemble the well body is determined according to the drilling depth. During assembly, the first pipe sections 2 are also connected to each other through the quick installation mechanism 5.

[0048] When the well body is used for a long time, many impurities will settle inside the sedimentation pipe 4. These impurities will affect the water quality monitoring of the groundwater layer, so regular cleaning is required. During cleaning, the sludge suction assembly 6 needs to be assembled together, the well cap 1 needs to be opened, and the sludge suction assembly 6 needs to be inserted into the assembled well body from the top of the first section pipe 2 so that the tail section sludge suction pipe 64 can contact the impurities at the bottom. The impurities, along with water, are then pumped from the tail section sludge suction pipe 64 into the sludge suction assembly 6 by the external water pump connected to the extraction pipe 62. The impurities are then transported to the external water pump from the extraction pipe 62 and extracted, thus completing the removal of impurities.

[0049] In a preferred embodiment, please also refer to Figure 3 and Figure 4 The quick-installation mechanism 5 includes a first connector 51 and a second connector 52. Guide mounting blocks 55 are provided on both sides of the outer side of the first connector 51, and guide grooves 56 are provided on both sides of the inner side of the first connector 51. The guide grooves 56 are composed of vertical grooves and arc grooves. When the first connector 51 and the second connector 52 are connected, the guide mounting blocks 55 are aligned with the vertical grooves of the guide grooves 56. When the first connector 51 and the second connector 52 are fixed, the first connector 51 is rotated, and the guide mounting blocks 55 enter the arc grooves of the guide grooves 56.

[0050] In this embodiment, the first connector 51 is fixed to the bottom of the well cap 1, the first section pipe 2, and the filter mechanism 3, and the second connector 52 is fixed to the top of the first section pipe 2, the filter mechanism 3, and the sedimentation pipe 4. During the installation of the well cap 1 and the first section pipe 2, the first section pipe 2 and the first section pipe 2, the first section pipe 2 and the filter mechanism 3, and the filter mechanism 3 and the sedimentation pipe 4, the bottom of the first connector 51 is inserted into the second connector 52. When inserted, the guide mounting block 55 is aligned with the vertical groove of the guide groove 56. When the first connector 51 is inserted to the bottom, the first connector 51 is rotated so that the guide mounting block 55 rotates in the arc groove of the guide groove 56, so that the first connector 51 and the second connector 52 are connected and fixed, thereby enabling the assembly of the well body to be quickly assembled.

[0051] Secondly, please refer to the following: Figure 3 and Figure 4 The first connector 51 has sliding grooves on both sides, and springs 59 are installed in the sliding grooves. A locking rod 58 is slidably connected in the sliding grooves. One end of the locking rod 58 is located at the guide mounting block 55, and the other end of the locking rod 58 is in contact with the spring 59. A slope is provided at the bottom of one end of the locking rod 58. A locking hole 57 is provided at one end of the arc groove of the guide groove 56.

[0052] As described above, after the first connector 51 and the second connector 52 are assembled, the guide mounting block 55 moves to one end of the arc-shaped groove of the guide groove 56. At this time, the locking rod 58 set at the guide mounting block 55 is aligned with the locking hole 57, and the locking rod 58 will pop out under the action of the spring 59, so that the locking rod 58 is inserted into the locking hole 57, which can lock the first connector 51 and the second connector 52, thereby preventing the loosening of the various connection points of the assembled well body. When it is necessary to disassemble the first connector 51 and the second connector 52, the locking rod 58 is retracted by pressing the tool at the same time, so that the locking rod 58 is retracted into the arc-shaped groove of the guide groove 56 and the guide groove 56 is rotated to release the lock and disassemble the first connector 51 and the second connector 52.

[0053] Secondly, please refer to the following as well. Figure 3 and Figure 4 The bottom of the first connector 51 is fixed with a first sealing plate 53, and the top of the inner side of the second connector 52 is fixed with a second sealing plate 54.

[0054] As described above, after the first connector 51 is inserted into the second connector 52, the second sealing plate 54 and the first sealing plate 53 are fitted together. The sealing performance of the first connector 51 and the second connector 52 after assembly can be increased by the first sealing plate 53 and the second sealing plate 54.

[0055] In a preferred embodiment, with Figure 5 For example, the cleaning component 7 includes a first connecting rod 71, a middle connecting rod 72, and a last connecting rod 73. The first connecting rod 71 is located inside the first suction pipe 61, and the top of the first connecting rod 71 is rotatably connected to the first suction pipe 61. An external drive device is provided on the top of the first connecting rod 71 and above the first suction pipe 61. The middle connecting rod 72 is located inside the middle suction pipe 63, and the last connecting rod 73 is located inside the last suction pipe 64. Support frames 74 are rotatably connected to the outer sides of the first connecting rod 71, the middle connecting rod 72, and the last connecting rod 73. Several support frames 74 are fixed to the inner walls of the first suction pipe 61, the middle suction pipe 63, and the last suction pipe 64, respectively. Agitator rods 75 are also evenly provided on the outer sides of the first connecting rod 71, the middle connecting rod 72, and the last connecting rod 73.

[0056] Furthermore, the first connecting rod 71 and the middle connecting rod 72, as well as the middle connecting rod 72 and the tail connecting rod 73, are all connected by threads.

[0057] In this embodiment, after aligning the extraction pipe 62 with the middle section sludge suction pipe 63, the first section connecting rod 71 and the middle section connecting rod 72 installed inside the extraction pipe 62 and the middle section sludge suction pipe 63 will also be aligned. By rotating, the first section connecting rod 71 and the middle section connecting rod 72 can be fixed together by the action of the threads. Similarly, when installing the middle section sludge suction pipe 63 and the tail section sludge suction pipe 64, the middle section connecting rod 72 and the tail section connecting rod 73 are also fixed together by rotation. When extracting impurities, the first section connecting rod 71 can be driven to rotate by the external drive device connected to the top of the first section connecting rod 71, which will drive the middle section connecting rod 72 and the tail section connecting rod 73 to rotate together. During the rotation, the stirring rod 75 will be driven to rotate. During the rotation, the impurities can be dispersed, so that the impurities can be evenly dispersed into the water and can be extracted more easily.

[0058] The support frame 74 serves to support the first connecting rod 71, the middle connecting rod 72 and the tail connecting rod 73, and the sludge suction assembly 6 and the cleaning assembly 7 are rotatably connected through the support frame 74.

[0059] In a preferred embodiment, please refer again. Figure 7 A cleaning brush 76 is fixed on the outer side of the bottom of the tail section connecting rod 73. The cleaning brush 76 is located at the bottom of the tail section suction pipe 64 and is rotatably connected to the tail section suction pipe 64.

[0060] In this embodiment, when the tail section connecting rod 73 rotates, it can drive the cleaning brush 76 to rotate as well, which can clean the inner wall of the assembly well body. At the same time, when the sludge suction component 6 is raised and lowered, the cleaning brush 76 is raised and lowered as well, and the inner wall of the entire assembly well body is cleaned during the rotation and raising and lowering process.

[0061] Secondly, please refer to the following: Figure 5 and Figure 6 The first section of the sewage suction pipe 61, the extraction pipe 62 and the middle section of the sewage suction pipe 63 are all equipped with a lower pipe support assembly 8. The lower pipe support assembly 8 includes an installation ring 81 and guide wheels 82. The installation ring 81 is fixed on the outside of the first section of the sewage suction pipe 61, the extraction pipe 62 and the middle section of the sewage suction pipe 63. There are multiple guide wheels 82, and multiple guide wheels 82 are rotatably installed on the outside of the installation ring 81.

[0062] As described above, when the sludge suction component 6 is inserted into the assembly well body, the guide wheel 82 located on the outer side will fit against the inner wall of the assembly well body, which will support the sludge suction component 6 and prevent the sludge suction component 6 from tilting when it is inserted into the assembly well body.

[0063] The working principle of this invention is as follows: During construction, a small auger drill is used to rotate downwards at a predetermined position to form a wellbore to the groundwater layer. During the drilling process, the first section pipe 2, the filter mechanism 3, and the sedimentation pipe 4 are assembled together using a quick-installation mechanism 5, and then lowered into the wellbore. After being fully installed in the wellbore, the well cap 1 is installed on top of the first section pipe 2 using the quick-installation mechanism 5, completing the assembly of the well body. Over time, impurities accumulate at the bottom and on the inner wall of the assembled well body, which can affect subsequent water quality monitoring. In this case, the sludge suction component 6 needs to be lowered into the assembly well body. During the lowering process, the cleaning component 7 is rotated by an external drive device. During the process, the cleaning brush 76 can clean the inner wall of the assembly well body. After the sludge suction component 6 is completely lowered to the bottom of the assembly well body, the water pump is started. When the cleaning component 7 rotates, it can break up the impurities at the bottom of the assembly well body. When pumping water, the impurities can be extracted together. After the impurities are completely removed, the sludge suction component 6 and the cleaning component 7 can be taken out of the assembly well body, and water source monitoring can continue.

[0064] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
