[0002] The low-level heat source of the ground source heat pump system indirectly absorbs the heat energy of shallow underground water, rocks and soil layers through a closed circulation loop pre-buried underground. This method does not directly extract groundwater, so it will not affect the balance and quality of groundwater.

[0003] As an important way to obtain underground heat energy in the ground source heat pump system, ground source water wells need to be cleaned frequently to ensure the natural flow of well water, improve water extraction efficiency, and maintain the quality of groundwater resources.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0022] See also Figure 1 A preferred embodiment of a ground source water well cleaning and maintenance tool. In this embodiment, the ground source water well cleaning and maintenance tool is used to clean the ground source water well and inspect the well wall during the cleaning process; the main structure of the ground source water well cleaning and maintenance tool includes a frame bracket and a telescopic working unit. In different embodiments, the frame bracket and the telescopic working unit can be an integrated structure to obtain better structural stability; or they can be a detachable and separable structure to facilitate storage, management, transportation, and maintenance.

[0023] The frame support of this embodiment is a fixed structure, which is used to adapt to the wellhead of a single size of the water well. The frame support includes a circular outer frame 1 on the outer edge, which matches the wellhead size of the well wall 7 of the water well, and a downward-turned buckle structure is formed at the outer contour position of the circular outer frame 1. The buckle structure can be buckled on the outside of the wellhead when the circular outer frame 1 is buckled at the wellhead position of the water well to prevent the frame support from shifting during operation. A star-shaped bracket body 2 is formed on the inner side of the circular outer frame 1. The bracket body 2 is welded to the circular outer frame 1 on the outer side as a whole, and a casing seat 6 is welded on the inner side, and the casing seat 6 corresponds to the axial position of the water well.

[0024] In this embodiment, the circular outer frame 1, the bracket body 2 and the sleeve seat 6 are all formed of steel structure materials to ensure the overall structural strength of the frame bracket and the structural stability during operation.

[0025] In another embodiment, the corresponding frame bracket can be set as a cross-shaped bracket, the outer sides of the horizontal rod and the vertical rod of the cross-shaped bracket are telescopic structures, and the outer ends of the horizontal rod and the vertical rod are formed with reverse folding structures; this form of frame bracket can adapt to the wellhead sizes of water wells of different sizes and shapes by adjusting the length of the horizontal rod and the vertical rod.

[0026] The telescopic operation unit of this embodiment includes a telescopic rod 8, a working head 11 and a driving part 3. The telescopic rod 8 in the telescopic operation unit is sleeved in a sleeve seat 6. The upper part of the telescopic rod 8 is assembled and connected with the working head 11 through an assembly seat, and the lower part is detachably assembled and connected with the working head 11 through a threaded screw connection structure. The telescopic rod 8 is a hollow rod body, and a length-adjustable hose 5 is installed in the rod body. The telescopic rod 8 uses a gear rack mechanism as a telescopic mechanism to perform telescopic operation.

[0027] The working head 11 of this embodiment includes a base, which is cylindrical and is screwed and fixed on the upper end surface by a threaded screw connection structure that matches the lower end of the telescopic rod 8. The working head 11 is formed with a ring-shaped LED light strip 9 on the upper part of the outer side of the screw connection part, and a pressurized nozzle 10 arranged in a ring array is formed on the outer edge of the lower part (corresponding to the middle position of the base) of the ring-shaped LED light strip 9, and a brush part is formed on the outer edge of the lower part (corresponding to the lower position of the base), and a plurality of vertically arranged brush strips are arranged on the brush part, and these brush strips are evenly arranged on the outer ring surface of the base.

[0028] The working head 11 includes a closed housing, in which a first driving motor for driving a gear rack mechanism, a second driving motor for driving the entire telescopic rod 8 to rotate, and an electronic control unit for realizing the corresponding functions of the first driving motor and the second driving motor are enclosed. A battery assembly position is also reserved on the closed housing of the working head 11, and the above-mentioned operation of the first driving motor and the second driving motor can be realized by inserting a charged detachable battery 4 into the battery assembly position.

[0029] During the operation of the first driving motor, as the telescopic rod 8 is extended and retracted, the hose 5 installed in the rod will also extend and retract accordingly. In order to improve the smoothness of the flexible tube 5's follow-up extension and retraction, in another embodiment, a coil wheel similar to a kite coiling structure can be set at the assembly seat where the driving part 3 and the telescopic rod 8 are assembled and connected. The hose 5 is coiled on the coil wheel, and during the extension and retraction of the telescopic rod 8, the coil wheel rotates accordingly, thereby realizing the follow-up extension and retraction of the hose 5. The hose 5 is clamped in the outlet groove reserved on the housing of the driving part 3 at the upper end of the telescopic rod 8, and extends out from the outside of the outlet groove of the driving part 3; the outer end of the hose 5 is connected to the water supply device.

[0030] When the ground source water well cleaning and maintenance tool of this embodiment is in operation, the frame support and the telescopic operation unit are assembled first, and the operation can be carried out after the assembly is completed. During the operation, the telescopic rod 8 extends downward and rotates at the same time. During the rotation process, the pressurized nozzle 10 starts to spray water continuously, and the sprayed water can be used to moisten the well wall 7 of the water well, so as to facilitate the brush part 12 to brush during the rotation process. At the same time, after the brushing is completed, a water washing effect similar to high-pressure water gun cleaning can be achieved. The corresponding annular LED light strip 9 is used for visual observation by the operator to realize the maintenance of the well wall 7 of the water well, and the cleaning effect can also be observed. When the cleaning is not in place at a specific position, the telescopic rod 8 can be controlled to retreat to perform multiple reciprocating cleaning.

[0031] In order to improve the convenience of the ground source water well cleaning and maintenance tool of this embodiment, a tool storage box can also be set on the corresponding frame support for placing maintenance and maintenance tools. In addition, the corresponding driving part 3 can also be connected to an external power supply through a power line for power supply.

[0032] In addition, in this embodiment, a crank rocker arm can be provided on the driving part 3 as a driving structure to enable manual operation when the electric drive fails or is unavailable.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
