For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0021] In the embodiment of the utility model, this case provides an electric drive device for a reel, which is used to reel or release a hose (not indicated), including a module housing 100, a rotating motor 110, a transmission shaft 120, a coupling screw 130, a limit switch group 200 and an abutment portion 230. The module housing 100 is provided with a rotating motor 110, a transmission shaft 120 and a coupling screw 130, one end of the transmission shaft 120 and one end of the coupling screw 130 are respectively connected to the front end and the rear end of the driving part of the rotating motor 110, the transmission shaft 120 and the coupling screw 130 are located on the same horizontal line, and the transmission shaft 120 and the coupling screw 130 rotate synchronously under the drive of the rotating motor 110, and the transmission shaft 120 will reel or release the hose. The coupling screw 130 is provided with a driving platform 140 threadedly connected thereto, and the driving platform 140 is provided with an abutment portion 230, and the driving platform 140 moves in a direction of approaching or moving away under the rotation of the coupling screw 130. The module housing 100 is also connected to the receiving seat 150 , on which a limit switch group 200 is provided. When the limit switch group 200 abuts against the abutting portion 230 , the rotating motor 110 stops running.

[0022] Specifically, the main function of the transmission shaft 120 is to drive the storage or release of the hose. When the rotary motor 110 rotates forward, the transmission shaft 120 rotates accordingly to achieve the storage of the hose; when the rotary motor 110 rotates reversely, the transmission shaft 120 rotates reversely to achieve the release of the hose. The coupling screw 130 is provided with a driving platform 140 threadedly connected thereto, and the driving platform 140 is provided with an abutment portion 230. Under the rotation of the coupling screw 130, the driving platform 140 will move in a direction close to or away from the transmission shaft 120. This movement process realizes the stoppage of the rotary motor 110 through the interaction between the abutment portion 230 and the limit switch group 200, thereby ensuring the accurate release of the hose. The automatic storage and release of the hose is realized by electric means, which greatly improves work efficiency and reduces labor intensity.

[0023] In another embodiment of the utility model, the limit switch group 200 includes a positive limit switch 210 and a reverse limit switch 220, the positive limit switch 210 and the reverse limit switch 220 are respectively installed at the front and rear ends of the receiving seat 150, and the abutment portion 230 is divided into a positive abutment end 240 and a negative abutment end 250, and the positive abutment end 240 and the negative abutment end 250 are respectively installed at the front and rear ends of the driving platform 140, and under the rotation of the coupling screw 130, the positive abutment end 240 abuts against the positive limit switch 210, and the reverse abutment end abuts against the reverse limit switch 220, both of which stop the rotation motor 110. Specifically, in the forward rotation mode of the rotating motor 110, under the forward rotation of the coupling screw 130, the driving platform 140 will perform a linear motion along the direction of the coupling screw 130. When the driving platform 140 moves toward the direction close to the transmission shaft 120, the positive abutting end 240 will contact the positive limit switch 210, triggering the switch signal, causing the rotating motor 110 to stop running, thereby achieving accurate storage of the hose. Conversely, when the rotating motor 110 is in reverse mode, under the reverse rotation of the coupling screw 130, the driving platform 140 moves away from the transmission shaft 120, and the negative abutting end 250 will contact the reverse limit switch 220, also triggering the switch signal, causing the rotating motor 110 to stop, thereby completing the accurate storage and release of the hose.

[0024] In another embodiment of the utility model, the positive abutment end 240 and the negative abutment end 250 are both made of positioning screws 260 and positioning nuts 270; both ends of the driving platform 140 are provided with connecting plates extending outward, and the positioning screws 260 pass through the connecting plates and are threadedly connected with the positioning nuts 270 to adjust the length of the abutment end. Specifically, in order to meet the needs of different lengths or different storage / release strokes, an adjustable abutment end design is proposed. Specifically, the positive abutment end 240 and the negative abutment end 250 are both made of positioning screws 260 and positioning nuts 270. Such a design allows the user to adjust the length of the abutment end according to actual needs. The positioning screw 260 passes through the connecting plate and is threadedly connected with the positioning nut 270. By rotating the positioning nut 270, the position of the positioning screw 260 in the connecting plate can be pushed, thereby changing the effective length of the abutment end.

[0025] In another embodiment of the utility model, the receiving seat 150 is further provided with a first connecting platform 280 and a second connecting platform 290. The first connecting platform 280 passes through the coupling screw 130 and is connected to one end close to the module housing 100; the second connecting platform 290 is connected to the other end of the coupling screw 130. The two connecting platforms are respectively located on the receiving seat 150, and are used to fix and support the coupling screw 130 to ensure that it remains stable during the rotation process. The two connecting platforms are fixed together by welding, bolt connection or other means to ensure that the coupling screw 130 does not shake or deviate during the transmission process.

[0026] In another embodiment of the utility model, a protective plate 300 is further provided on the module housing 100, and the protective plate 300 is installed on the module housing 100 and close to one end of the transmission shaft 120. The protective plate 300 is usually made of a solid material such as metal or hard plastic to ensure that it has sufficient height and durability to prevent the hose from interfering with the operation of the coupling screw 130 when winding.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
