Referring to fig. 1 and fig. 2, an electric putter device 10 includes a protective casing 100, a transmission assembly 200, a telescopic assembly 300, and a base assembly 400.
Thus, it should be noted that the protective shell 100 plays a role in protection and waterproofing, so as to prevent the internal structure of the electric putter device 10 from being damaged, and at the same time, prevent water droplets from infiltrating into the electric putter device 10 and causing short circuit of the electric putter device 10; the transmission kit 200 functions as a power take-off. The generated power is transmitted to the outside by means of the telescopic sleeve 300, and some automatic opening or closing work is completed; the base kit 400 plays a role in draining water, and can drain water drops remained in the protective shell 100, so as to prevent the water drops from permeating into the protective shell 100 and causing short circuit of the electric putter device 10.

Therefore, it should be noted that, when the transmission driving assembly 210 outputs power to make the nut 240 slide up and down relative to the screw rod 230, since the telescopic tube 310 is connected to the nut 240, the telescopic tube 310 can slide along the axial direction of the external tube 320 under the driving of the nut 240, thereby completing the automatic opening or closing operation. When the electric putter device 10 is applied to an automatic farm raising shed, for example, if a door of the automatic farm raising shed is to be automatically opened or closed by using the electric putter device 10, the telescopic tube 310 is connected to the door, and when the door is to be opened, the transmission driving assembly 210 outputs power to move the nut 240 in a direction close to the transmission driving assembly 210, and at this time, the door is automatically opened by the telescopic tube 310; when the door needs to be closed, the transmission driving assembly 210 outputs power to move the nut 240 away from the transmission driving assembly 210, and at this time, the door is automatically closed (i.e., the door is reset to the closed state) under the action of the telescopic tube 310.
Referring to fig. 1, 3, 4 and 5, the base kit 400 includes a drainage plate 410, a base body 420 and a drainage pipe 430, the drainage plate 410 is connected to the protective shell 100, the drainage plate 410 is provided with a plurality of transverse grooves 411 and a plurality of longitudinal grooves 412, the transverse grooves 411 are in one-to-one correspondence to the longitudinal grooves 412 and are in staggered communication, a drainage hole 413 is formed at a communication position of each transverse groove 411 and each longitudinal groove 412, a drainage arc 413a is arranged at an edge position of each drainage hole 413, the base body 420 is arranged on the drainage plate 410, the drainage pipe 430 is arranged in the base body 420, one end of the drainage pipe 430 is communicated with each drainage hole 413, and the other end of the drainage pipe 430 is exposed out of the base body 420.
Thus, it should be noted that the base kit 400 plays a role of draining water, when too many water drops remain on the protective shell 100, the water drops may fall onto the drainage plate 410 due to gravity, because the drainage plate is provided with the plurality of transverse grooves 411 and the plurality of longitudinal grooves 412, the communication position between each transverse groove 411 and each longitudinal groove 412 is provided with the drainage hole 413, and the water drops falling onto the drainage plate 410 can be drained onto the drainage pipe 430 due to the existence of the drainage hole 413, and the drainage pipe 430 drains the water drops again, so as to prevent the water drops from remaining on the protective shell 100 for a long time and too much, which causes the water drops to permeate into the protective shell 100 and causes short circuit of the electric putter device 10; in addition, in order to discharge the water drops on the drainage plate 410 more smoothly, the edge of each drainage hole 413 is provided with a drainage arc 413a, and the drainage arc 413a is arranged; furthermore, because each transverse groove 411 and each longitudinal groove 412 are designed as a groove body, when water drops flow into each transverse groove 411 and each longitudinal groove 412, the probability of the water drops contacting the protective shell again can be reduced, that is, because of the groove body design, each transverse groove 411 and each longitudinal groove 412 have a certain groove depth and the water drops can be discharged from the drainage holes 413, when the water drops flow into each transverse groove 411 and each longitudinal groove 412, the overall height of the water drops is generally not greater than the groove depth of each transverse groove 411 and each longitudinal groove 412, so that the water drops falling into each transverse groove 411 and each longitudinal groove 412 can be well prevented from contacting the protective shell 100 again, the probability of the water drops contacting the protective shell 100 again can be greatly reduced, and the water drops are prevented from permeating into the protective shell 100 for a long time to cause the water drops to enter the protective shell 100 to cause the short circuit of the electric putter 10.
It should be noted that, the opening of each transverse slot 411 and each longitudinal slot 412 can increase the air amount of each transverse slot 411 and each longitudinal slot 412 due to the slot body structure design, i.e. accelerate the air flow, even if some water drops do not fall into the drain hole 413, because the air flow rate of each transverse slot 411 and each longitudinal slot 412 is fast, the water drops accumulated in each transverse slot 411 and each longitudinal slot 412 can be quickly evaporated due to the acceleration of the air flow rate, and the water drops in each transverse slot 411 and each longitudinal slot 412 are prevented from accumulating too much and contacting the protective shell 100 again, so that the water drops penetrate into the protective shell 100, and the electric putter device is short-circuited.
Further, referring to fig. 3 again, in an embodiment, the base kit 400 further includes a left rib plate 440 and a right rib plate, the left rib plate 440 is disposed in the base body 420, and the right rib plate is disposed in the base body 420.

Specifically, the elastic member 453 is a spring. Of course, the elastic member 453 can be made of other materials with buffering performance, and is not limited to a spring.
It should be noted that, due to the arrangement of the foot piece 452, the rubber cylinder 451 is not directly contacted with the ground, but the friction force between the rubber cylinder 451 and the ground is much greater than the friction force between the foot piece 452 and the ground, that is, the ground gripping force is stronger, therefore, in consideration of this point, a side surface of the foot piece 452 close to the ground can be provided with a plurality of anti-slip patterns, and the design of the anti-slip patterns can ensure that the foot piece 452 has better ground gripping force, so that the electric putter device can be placed on the ground more stably.

It should be noted that, in the practical application process of the electric putter device, since the electric putter device is an electronic device, heat is inevitably generated in the working process of the electric putter device, if the internal heat is not processed in time, too high heat is accumulated in the electric putter device, the service life of the electric putter device is greatly shortened, and in a serious case, the electric putter device may be damaged. There are three general heat dissipation methods, the first is natural heat dissipation, the second is air cooling heat dissipation, and the third is water cooling heat dissipation. However, the most basic principle of any heat dissipation method is to realize heat dissipation by using the heat exchange principle. Most traditional electric push rod devices rely on natural heat dissipation to realize heat dissipation, but the efficiency of the natural heat dissipation is too low to quickly dissipate heat in a short time. Most of the existing electric push rod devices are cooled by additionally arranging a radiator on the body, but most of the existing radiators only adopt a cooling mode, and once the radiator is damaged, the radiator loses the cooling function, so that the electric push rod devices cannot be cooled well.
Therefore, in order to prevent the electric putter device from accumulating too high heat inside and to enable the electric putter device to operate more stably, please refer to fig. 7 and 8, in an embodiment, the electric putter device 10 further includes a heat sink 600, the heat sink 600 includes a heat collecting component 610, a heat conducting component 620, an air cooling component 630 and a water cooling component 640, the heat collecting component 610 includes a heat collecting cover 611, a contact cone top 612 and a rubber ring, an embedding groove 611a is formed on the heat collecting cover 611, the heat collecting cover 611 is disposed on the protective shell 100, the contact cone top is located in the heat collecting cover, a small diameter end of the contact cone top is connected with the heat collecting cover, a large diameter end of the contact cone top 612 is in contact with the protective shell 100, the rubber ring is embedded in the embedding groove 611a, the heat conducting component 620 includes a transmission pipe and a plurality of heat dissipation fins, the transfer pipe is arranged on the heat collecting cover 611, each heat dissipation fin 621 is arranged on the transfer pipe, a space is arranged between every two adjacent heat dissipation fins 621, and each heat dissipation fin 621 is provided with a corner portion 621a at the corner position; the air cooling assembly 630 comprises a heat exchange tube 631, a protective shell 632, a heat dissipation fan, a battery pack and a dust screen 633, wherein one end of the heat exchange tube 631 is connected with the transfer tube, the other end of the heat exchange tube 631 is connected with the protective shell 632, the heat dissipation fan is arranged in the protective shell 632 and can rotate relative to the protective shell 632, the battery pack is arranged in the protective shell 632, the battery pack is electrically connected with the heat dissipation fan, and the dust screen 633 is arranged on the protective shell 632; the water cooling assembly 640 includes a heat conducting pipe 641, a heat radiating pipe 642, a water pump 643 and a plurality of auxiliary heat radiating teeth 644, wherein the heat conducting pipe 641 is disposed on the heat exchanging pipe 631, the heat radiating pipe 642 is communicated with the heat conducting pipe 641, the water pump 643 is respectively communicated with the heat conducting pipe 641 and the heat radiating pipe 642, each auxiliary heat radiating tooth 644 is disposed on a side wall of the heat radiating pipe 642, and a space is disposed between two adjacent auxiliary heat radiating teeth 644.
In this way, when the heat sink 600 needs to dissipate the heat of the electric putter device 10, first, the large diameter end of the contact cone top 612 contacts the protective shell 100 (the difference between the large diameter end and the small diameter end is that the diameter of the large diameter end is larger than that of the small diameter end), the contact cone top 612 transfers heat to the transfer pipe, the transfer pipe transfers the heat to each radiating fin 621, each radiating fin 621 radiates the heat to the air by virtue of the heat exchange effect with the air, the flow completes the heat radiation by virtue of a natural heat radiation mode, and at the same time, because each heat dissipation feather 621 is provided with unfilled corner portion 621a on corner position department, the setting of unfilled corner portion 621a can increase the area of contact between each heat dissipation feather 621 and the air for each heat dissipation feather 621's heat exchange efficiency lets each heat dissipation feather 621 can distribute out the heat rapidly, cools down electric putter device 10 rapidly.
It should be further noted that, because the heat dissipation efficiency of the natural heat dissipation mode is limited, in order to dissipate the internal heat of the electric putter device 10 in a short time as much as possible, the heat sink 600 of the present application also considers two heat dissipation modes, namely, when performing air cooling heat dissipation, the battery pack inputs voltage to the heat dissipation fan to drive the heat dissipation fan to rotate, and the heat exchanged between the heat exchange pipe 631 and the transmission pipe is dissipated by the heat generated by the heat dissipation fan, so as to achieve an air cooling heat dissipation process; when water cooling heat dissipation is required, water flows between the heat conducting pipe 641 and the heat dissipating pipe 642 by power output by the water pump 643, the heat conducting pipe 641 is disposed on the heat exchanging pipe 631, water flowing through the heat conducting pipe 641 exchanges heat with the heat exchanging pipe 631, when the water is transmitted to the heat dissipating pipe 642 by the power of the water pump 643, the heat dissipating pipe 642 exchanges heat with air, and the heat of the water is dissipated into the air, so that the heat is dissipated out quickly, and the electric putter device 10 is cooled quickly.
It should be further noted that, the heat sink 600 of the present application combines three modes of natural heat dissipation, air-cooled heat dissipation and water-cooled heat dissipation, and compared with the conventional heat dissipation method that only depends on one heat dissipation mode, the heat sink 600 of the present application can quickly dissipate heat inside the electric putter device 10, so as to effectively prevent the electric putter device 10 from being damaged due to excessive heat accumulated inside the electric putter device; in addition, the user can flexibly start air cooling heat dissipation and water cooling heat dissipation under the actual use condition to achieve the optimal heat dissipation mode, and meanwhile, the self energy consumption of the heat sink 600 can be properly reduced.
