Description

Technical Field

[0001] The present application relates to the field of water pump technology, and in particular to a novel submersible pump. Background Art

[0002] The float switch of the submersible pump is used to control the submersible pump to work within the effective maximum water level and minimum water level. Common water pumps are connected to the float switch through wires, and the length of the wires is used to control the height of the float to start and stop the water pump. The float switch rises and falls with the rise and fall of the water surface height in the working environment of the submersible pump. When the float rises to the highest position with the water level, the switch inside the float is turned on to start the submersible pump. When the float drops to the lowest permitted position with the water level, the switch inside the float is turned off to stop the water pump. This protects the water pump from working safely within the effective water level. However, in actual work, the float switch floats and is inconvenient to fix its position, so that the control of different water levels may require special supervision. In addition to the control of different water levels, there is also a demand for continuous start of the submersible pump in various application scenarios.

[0003] In order to improve the simplicity of continuous starting of submersible pumps and automatic control of different water levels of submersible pumps, we propose a new submersible pump. Utility Model Content

At this time, the water pump is in a normally open state; the user inserts the connecting frame of the wire clamp into the automatic control gear frame when the float switch is in a horizontal direction, so that the wire clamp The connecting piece is inserted and connected at the hole, the clamp body is clamped on the third groove and the fourth groove of the first protrusion, and the second protrusion of the clamp body is clamped on the fourth groove, thereby realizing the relative rotation of the wire clamp and the automatic control gear frame, so that the float switch floats and rotates upward on the automatic control gear frame through the wire clamp as the water level rises, and conversely, the float switch rotates and tilts downward by its own gravity, thereby realizing the automatic control function of the water pump, and the fourth protrusion limits the clamping mouth of the wire clamp body, so that the wire clamp and the wire clamp frame are connected without affecting the relative rotation of the wire clamp and the wire clamp frame, and the connection between the wire clamp and the wire clamp frame can also be stably limited between the fourth protrusion and the second protrusion;

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The embodiment of the present application discloses a new submersible pump.

[0027] Reference Figure 1 , including a pump body 1 and a float switch 2. The float switch 2 is connected to the driving mechanism of the pump body 1 through an electric wire, so that the pump body 1 drives the float switch 2, and then the start and stop of the water pump is controlled by the float switch 2. The float switch 2 includes a shell, a micro switch, a fence and a metal ball. The micro switch, the fence and the metal ball are all located inside the shell. The shell is generally flat, so that the float switch 2 can float on the water surface with two fixed surfaces. The fence is glued to the shell and surrounds an arc space. The metal ball is placed in the arc space surrounded by the fence, so that when the direction of the float switch 2 changes, the metal ball is moved by The micro switch moves in the arc space due to its own weight, and the micro switch part is located in the arc space. The micro switch is located at the end of the float switch 2 away from the pump body 1, so that when the end of the float switch 2 away from the pump body 1 tilts downward, the metal ball squeezes the micro switch due to its own weight. When the float switch 2 tilts upward, the metal ball moves away from the micro switch due to its own weight. The wire connected to the float switch 2 is connected with a wire clamp 6, and the pump body 1 is integrally connected with a wire clamp frame 3. The user controls the position height and direction of the float switch 2 by connecting the wire clamp 6 with the wire clamp frame 3, thereby realizing the control and adjustment of the water level of the water pump environment.

[0028] refer to Figure 2The outer wall of the water pump is integrally connected with a plurality of wire clamp frames 3 in the vertical direction. The wire clamp frame 3 is a first protrusion 5 with a hole 4. The first protrusion 5 is annular, so that the wire clamp 6 can be rotated after being connected to the wire clamp frame 3. The wire clamp frame 3 includes a normally open gear frame 11 and a plurality of automatic control gear frames 12, so that the wire clamp 6 will not rotate when the wire clamp 6 is connected to the normally open gear frame 11. When the wire clamp 6 is connected to the automatic control gear, the wire clamp 6 rotates upward or downward appropriately under the buoyancy or gravity of the float switch 2. The normally open gear frame 11 is on the first protrusion 5. The outer wall of the first protrusion 5 is provided with a first groove 13, so that the first groove 13 cooperates with the wire clamp 6 to limit the rotation of the wire clamp 6, the first protrusion 5 is provided with a second groove 14 at a position near the first groove 13 and the pump body 1, and the automatic control gear frame 12 is provided with a third groove 15 on the outer wall of the first protrusion 5, so that the wire clamp 6 can be appropriately rotated up or down when cooperating with the third groove 15, and the first protrusion 5 is provided with a fourth groove 16 at a position near the third groove 15 and the pump body 1, and multiple automatic control gear frames 12 meet the automatic control requirements of various different water levels.

[0029] refer to Figure 3 The wire clamp 6 includes a connecting piece 7 and a clamp body 8. The clamp body 8 has a clamping opening 9 for clamping and limiting. The connecting piece 7 is connected to the clamp body 8, so that when the connecting piece 7 is inserted and connected with the wire clamp frame 3, the clamp body 8 can be connected and limited with the wire clamp frame 3 through the clamping opening 9. A wire harness hole 18 is opened in the middle of the connecting piece 7. The connecting piece 7 is connected to the wires on the float switch 2 through the wire harness hole 18, so as to facilitate the limitation of the position of the float switch 2 and the rotation direction of the float switch 2. One end of the connecting piece 7 is a circular protrusion 26. The outer diameter of the circular protrusion 26 matches the inner diameter of the connecting frame hole 4, and the circular protrusion 26 is a circular protrusion 26. The protrusion 26 can rotate freely in the hole 4, and a chamfer is provided at the end of the circular protrusion 26 to increase the convenience of inserting the circular protrusion 26 into the hole 4. The connector 7 is integrally connected with a fourth protrusion 17 on the outer wall of the circular protrusion 26. The outer diameter of the fourth protrusion 17 is equal to the outer diameters of the first groove 13 and the third groove 15, so that the minimum clamping opening 9 of the clamp body 8 corresponds to the outer diameters of the first groove 13 and the third groove 15, so that the clamp body 8 and the wire clamp frame 3 will not be unable to rotate due to the clamping force. A spring hole 23 is also provided at the other end of the connector 7.

[0030] The outer wall of the connecting member 7 is symmetrically provided with a clamping body groove 22, and the side wall of the clamping body groove 22 of the connecting member 7 is symmetrically provided with a small hole 24. The clamping body 8 includes two clamping members 19 and a spring 20. The two sides of the two clamping members 19 are integrally connected with a rotating rod 25. The two clamping members 19 are respectively located in the two clamping body grooves 22. The clamping body groove 22 allows part of the clamping body 8 to be hidden in the connecting member 7, making the appearance of the wire clamp 6 more smooth and increasing the aesthetics of the wire clamp 6. The clamping body groove 22 can also further limit the position of the clamping body 8 to avoid unnecessary displacement, strengthen the overall firmness of the wire clamp 6, and provide the clamping body 8 with more supporting area. The clamping member 19 rotates with the connecting member 7 through the cooperation of the rotating rod 25 and the small hole 24. The two clamps 19 are connected with a third protrusion 21 at one end near the spring hole 23 of the connecting member 7, and the position of the third protrusion 21 corresponds to the position of the spring hole 23. The two ends of the spring 20 are respectively connected with the two third protrusions 21 and are located in the spring hole 23. The spring 20 has a preload force. The user opens the clamp 9 by pressing the spring 20 position of the clamp body 8, so that the clamp 9 can clamp the first protrusion 5. After the user gives up pressing the clamp 8 at the spring 20 position, the spring 20 rebounds and the clamp 9 restores the minimum clamp 9. The two clamps 19 are connected with a second protrusion 10 in the clamp 9, so that when the clamp 8 is clamped on the first protrusion 5, the second protrusion 10 of the clamp 8 The second groove 14 and the fourth groove 16 of the first protrusion 5 are stuck, so that the clamp body 8 is limitedly connected with the first protrusion 5. During specific use, the float switch 2 is vertically inserted into the normally open gear frame 11 through the wire clamp 6. Due to the engagement of the clamp 19 with the first groove 13, the clamp 19 cannot rotate in the normally open gear, and then the clamp body 8 cannot rotate in the normally open gear, so that the float switch 2 always remains in a vertical upward state, so that the metal ball in the float switch 2 cannot contact the micro switch, and then the water pump always remains in the normally open gear. The ball in the float switch 2 will not press the micro switch, so that the float switch 2 will not rise and fall due to the rise and fall of the working environment of the water pump; when When the user needs the water pump to be in the automatic control gear, the float switch 2 inserts the wire clip 6 horizontally and connects it to the automatic control gear frame 12, and the clamp 19 is clamped by the second protrusion 10 and the fourth groove 16 of the first protrusion 5, so that the clamp body 8 cannot be separated from the automatic control gear frame 12, and because the third groove 15 and the fourth groove 16 are larger than the clamp body 8, the clamp body 8 can rotate in the automatic control gear, so that the float switch 2 rises due to the buoyancy as the water level of the water pump environment rises, and rotates downward under the action of its own gravity as the water level of the water pump environment drops, so that the metal ball in the shell of the float switch 2 also descends under the action of gravity, thereby triggering the micro-switch, thereby limiting the water level of the water pump environment.

[0031] Furthermore, in this embodiment, the fourth protrusion 17 may also be located in the clamping opening 9 , as long as the minimum value of the clamping opening 9 is greater than or equal to the first groove 13 and the third groove 15 .

[0032] Furthermore, in this embodiment, other plug-in methods may be used between the wire clamp 6 and the wire clamp frame 3, as long as the directional fixation / rotational fixation of the float switch 2 connected to the wire clamp 6 can be achieved.

[0033] The implementation principle of a new submersible pump disclosed in the embodiment of the present application is as follows: the float switch 2 is connected to different wire clamp frames 3 through a wire clamp 6 to realize the conversion of the water pump into a normally open state or an automatic control state. When the wire clamp 6 is located on the normally open gear frame 11, the wire clamp 6 is firmly connected to the normally open gear frame 11 and will not rotate. When the wire clamp 6 is located on the automatic control gear frame 12, the wire clamp 6 will rotate upward along with the float switch 2 when the water level in the water pump environment rises, and rotate downward under the action of gravity of the float switch 2 when the water level in the water pump environment drops, thereby realizing the control of the opening and closing of the micro switch in the float switch 2, and then playing the role of the water level switch of the water pump environment.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
