[0002] In the fields of modern industry and agriculture, water pumps are one of the widely used devices for transporting water or other liquids. To ensure the safe operation and maintenance of water pumps, an effective water pump switch control mechanism is usually required.

[0003] Traditional water pump switches adopt the method of manual rotary switches. Specifically, for example, the Delixi 2P manual rotary water pump switch. When actually operating this kind of switch, it completely relies on manual control, which undoubtedly significantly increases the working intensity and burden of operators. Moreover, in some specific scenarios, there are also some potential problems. For example, when non-professional staff casually opens the water pump switch out of curiosity or due to misoperation, a series of adverse consequences may be caused. This may not only lead to abnormal operation of the water pump, resulting in waste of energy and wear of equipment, but also may cause safety accidents due to improper operation, bringing unnecessary losses and risks to production and life. For example, in industrial production, if non-staff misoperate to open the water pump, it may disrupt the original orderly production process, resulting in a decline in product quality or production delays. In agricultural irrigation, misoperation by non-staff may cause the irrigation time and water volume to get out of control, affecting the growth of crops and thus affecting agricultural harvests.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1-4 shown, in this embodiment, a locking device for a water pump switch includes: a cover body 1;

[0022] a fixing component 2, which is installed on the cover body 1 and is used to fix the cover body 1 on the water pump;

[0023] a rotating plate 3, which is rotatably installed at the top of the cover body 1. A rotating component 4 for driving the rotating plate 3 to rotate is installed on the cover body 1. An electric push rod 5 is fixedly inserted on the rotating plate 3, and a slide plate 6 is fixedly installed at the telescopic end of the electric push rod 5; the rotating component 4 includes a driving motor 41 fixedly installed on the fixed cover 11, a small gear 42 is fixedly installed at the output end of the driving motor 41, a large gear 43 is fixedly sleeved on the electric push rod 5, and the small gear 42 meshes with the large gear 43.

[0024] Limiting plates 7, the number of which is multiple, and the multiple limiting plates 7 are fixedly installed in a linear array at the bottom of the rotating plate 3.

[0025] The cover body 1 serves as the outer shell of the entire device, playing the role of protecting the internal components and fixing the entire device. The cover body 1 is made of transparent plastic material, and the situation of the water pump switch can be clearly observed. The fixing component 2 is installed on the cover body 1, and through its structural design, the cover body 1 is firmly fixed at the position of the water pump switch, ensuring the stability of the device during operation.

[0026] The rotating plate 3 is located at the axis of the top end of the cover body 1. The rotating assembly 4 is installed on the cover body 1 and is used to drive the rotation of the rotating plate 3. An electric push rod 5 is fixedly inserted on the rotating plate 3, and its telescopic end is fixedly installed with a sliding plate 6, which can be telescoped as needed, so as to push the sliding plate 6 to move up and down.

[0027] The limiting plates 7 are multiple components distributed in a linear array, and they are fixedly installed at the bottom of the rotating plate 3. When the electric push rod 5 pushes the sliding plate 6 to move, the limiting plates 7 can move down to both sides of the water pump switch knob along with it, and limit and fix the water pump switch knob, so that it will not rotate randomly under the influence of external things, and realize the precise control of the water pump switch.

[0028] During the actual working process, when it is necessary to turn on or off the water pump, start the driving motor 41 to drive the small gear 42 to rotate. Since the large gear 43 and the small gear 42 are meshed, the large gear 43 can be driven to rotate, and then the electric push rod 5 can be driven to rotate, so that the limiting plate 7 at its bottom can be rotated to the designated position, located on both sides of the water pump switch knob. Then start the electric push rod 5 to move down, push the sliding plate 6 to move, until the sliding plate 6 drives the limiting plate 7 to reach the set final position, located on both sides of the water pump switch knob, and the locking of the water pump switch knob can be realized, so that it cannot move. When it is necessary to switch, just start the driving motor 41, and the rotation of the electric push rod 5 can be realized, so as to drive the limiting plate 7 below it to rotate. When rotating, it pushes the knob of the water pump switch to rotate, realizing the automatic switch of the water pump, avoiding the time-consuming and laborious manual operation of the staff, reducing the labor intensity of the staff. At the same time, the setting of the cover body 1 protects the water pump switch to a certain extent, avoiding the problem that a series of adverse consequences may occur when non-professional staff casually open the water pump switch out of curiosity or misoperation.

[0029] As Figure 3 shown, the cover body 1 includes a fixed cover 11 and a sliding ring 12. The sliding ring 12 is slidably sleeved on the outer surface of the fixed cover 11. The rotating plate 3 is rotatably installed at the top end of the cover body 1. A positioning assembly 13 for fixing the sliding ring 12 is installed on the fixed cover 11. The positioning assembly 13 includes a long plate 131 fixedly installed on the outer peripheral side of the fixed cover 11. A U-shaped plate 132 is fixedly installed on the outer peripheral side of the sliding ring 12. An iron block 133 is slidably inserted on the U-shaped plate 132. A plurality of card slots 134 are constructed in an array distribution on the long plate 131. Magnets 135 are fixedly installed on the inner walls of the plurality of card slots 134. The long plate 131 passes through the U-shaped plate 132, and the iron block 133 is inserted into one of the card slots 134 and is magnetically connected to the magnet 135.

[0030] The cover body 1 is composed of a fixed cover 11 and a sliding ring 12. This design enables the length of the cover body 1 to be adjusted according to the size of the water pump switch, so as to adapt to water pumps of different models and sizes.

[0031] To ensure the stable positioning of the sliding ring 12 on the fixed cover 11, a positioning component 13 is installed on the fixed cover 11. The positioning component 13 is ingeniously designed and includes a long plate 131 fixedly installed on the outer peripheral side of the fixed cover 11. A U-shaped plate 132 is fixedly installed on the outer peripheral side of the sliding ring 12. An iron block 133 is slidably inserted into the U-shaped plate 132. A plurality of card slots 134 are constructed in an array distribution on the long plate 131. Magnets 135 are fixedly installed on the inner walls of these card slots 134. The long plate 131 passes through the U-shaped plate 132, and the iron block 133 is inserted into one of the card slots 134 to form a magnetic connection with the magnet 135.

[0032] The sliding ring 12 can slide on the fixed cover 11 as needed. Through the magnetic connection between the card slots 134 and the magnets 135 on the long plate 131, the precise positioning of the sliding ring 12 is achieved. This magnetic connection not only provides a stable fixing effect but also allows the position of the sliding ring 12 to be quickly adjusted when needed, improving the practicability and flexibility of the entire device.

[0033] As Figure 3 shown, the fixing component 2 includes two first half-rings 21 fixedly installed symmetrically at the bottom of the sliding ring 12. The bottom of the first half-ring 21 is fixedly installed with a second half-ring 22 through bolts.

[0034] By combining the two first half-rings 21 and sleeving them on both ends of the water pump switch, and then connecting and fixing the first half-ring 21 and the second half-ring 22 through bolts, it is convenient to position and fix the cover body 1 at the position of the water pump switch.

[0035] As Figure 4 shown, positioning plates 8 are slidably installed at the bottoms of a plurality of the limiting plates 7. A moving component 9 for driving the positioning plates 8 to move is installed at the bottoms of the limiting plates 7. The moving component 9 includes a moving motor 91 fixedly installed at the bottom of the limiting plate 7. A lead screw 92 is fixedly installed at the output end of the moving motor 91. The positioning plate 8 is threadedly connected to the lead screw 92.

[0036] The rotation assembly 4 is used to drive the electric push rod 5 to rotate, thereby driving the limit plate 7 and the positioning plate 8 at its bottom to rotate. As a result, the positioning plate 8 can be rotated to the width direction of the water pump switch knob. The positioning plate 8 is U-shaped and can be snap-connected to the knob of the knob. Then, the moving motor 91 is started to drive the lead screw 92 to rotate, thereby driving the positioning plate 8 threadedly connected thereto to move closer to the knob of the water pump switch for snap-connection, further stably fixing the knob, facilitating driving its rotation, and providing stable limit thereto. Even in the case where the water pump switch is damaged or the automatic rotation switch occurs, the snap-connection function of the positioning plate 8 can also limit and fix the knob to prevent the switch from being accidentally turned on. This design further improves the safety and reliability of the water pump switch, ensuring that the on / off state of the water pump can be stably controlled under various conditions.

[0037] The present utility model provides a locking device for a water pump switch, and the specific working principle is as follows:

[0038] During the actual working process, the two first half-rings 21 are combined and sleeved on both ends of the water pump switch. Then, the first half-ring 21 and the second half-ring 22 are connected and fixed by bolts, thereby facilitating the positioning and fixing of the cover body 1 at the position of the water pump switch. When it is necessary to turn on or off the water pump, the driving motor 41 is started to drive the small gear 42 to rotate. Since the large gear 43 and the small gear 42 are meshed, the large gear 43 can be driven to rotate, and then the electric push rod 5 can be driven to rotate, so that the limit plate 7 at its bottom can be rotated to the designated position, on both sides of the water pump switch knob. Then, the electric push rod 5 is started to move downward, pushing the sliding plate 6 to move until the sliding plate 6 drives the limit plate 7 to reach the set final position, on both sides of the water pump switch knob, to achieve the locking of the water pump switch knob, making it unable to move. When it is necessary to turn on or off the switch, only the driving motor 41 needs to be started, and the rotation of the electric push rod 5 can be realized, thereby driving the limit plate 7 below it to rotate. When rotating, the knob of the water pump switch is pushed to rotate, realizing the automatic on / off of the water pump.

[0039] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
