Description

Technical Field

[0001] This invention belongs to the field of water pump units, specifically an automatic rotating start cabinet for water pump units. Background Technology

[0002] Automatic pump unit rotation start-up is a control strategy that ensures stable operation of water supply / drainage systems, balances the working time of each pump, and extends the overall lifespan of the equipment. It is widely used in building water supply and drainage, industrial circulating water, and municipal water supply. The core of automatic pump unit rotation start-up is to sequentially start different pumps through a control system to achieve a balanced distribution of working time among multiple pumps. This control system is extremely complex, with a core PLC or dedicated pump controller containing built-in rotation logic. It can receive signals from detection units, record pump running time, and output start / stop commands. However, it still has the following drawbacks: The complex control system enables multiple water pumps to be started in rotation, which results in higher initial investment costs, greater sensitivity to power supply and environment, significant impact from single point of failure, and high maintenance threshold.

[0013] Preferably, the cabinet is equipped with a fixing frame inside, and the two annular sleeves and two fixing boxes are all fixedly installed on the fixing frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses an electrical control box set at equal angles on a ring frame. The electrical control box corresponds one-to-one with the water pumps on the water pump unit. By rotating the rotating block, the movable plate inside the electrical control box is moved in sequence, so that the first contact point contacts the second contact point and starts the corresponding water pump. The mechanical structure realizes the automatic rotation and starting of multiple water pumps in a cycle, thereby improving the control reliability of the water pump unit. 2. In this invention, a gear meshes with a gear ring on one side of the rotating block. One rotation of the gear can drive the rotating block to rotate, causing the pressure plate to rotate from a position corresponding to one electrical control box to a position corresponding to an adjacent electrical control box. This facilitates the automatic activation of the corresponding water pump by rotating the rotating block. 3. In this invention, an electromagnet generates a repulsive force on a magnetic block, driving an internal plate to move toward a rotating block, thereby pushing a pressing plate to move away from the rotating block. This allows the pressing plate to exert pressure on the hemispherical pressing block when the rotating block is rotating, enabling the first contact point to contact the second contact point, thus facilitating the start-up control of the water pump. 4. This invention facilitates the switching control of the water pumps that automatically rotate in a cycle on the water pump unit by controlling the number of rotations of the gear in a single operation. If there are six water pumps on the water pump unit, the number of water pumps that rotate in a cycle can be set to six, three, or two, which facilitates the control of the number of water pumps that rotate in a cycle when the rotation angle of the rotating block is the same. 5. In this invention, a first push rod is set on a first moving ring, and a second push rod is set on a second moving ring. The number of first push rods is different from the number of second push rods. When the two first moving rings or the two second moving rings are controlled to move, the conductive arc plate can be pushed to a position offset from the third contact. When the pressure plate on the rotating block rotates to the position corresponding to the electrical control box of the water pump that is not in use, the electromagnet is de-energized, so that the pressure plate moves back into the circumferential box, ensuring that the water pump that is not in use will not be started.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1-10 The present invention relates to an automatic rotation start cabinet for a water pump unit, comprising a cabinet body 1, a cabinet door 2 installed on the front of the cabinet body 1, a controller 3 installed on the cabinet door 2, and a water pump control component 4 installed inside the cabinet body 1.

[0019] The water pump control assembly 4 includes an annular frame 401 disposed inside the cabinet 1. The annular frame 401 is fixedly installed to the inner wall of the cabinet 1. An electrical control box 402 is mounted on the annular frame 401 at equal angles. A movable plate 403 is movably installed inside the electrical control box 402. A hemispherical pressure block 405 is disposed on the side of the electrical control box 402 near the axis of the annular frame 401. A pressure rod 404 is fixedly installed between the movable plate 403 and the hemispherical pressure block 405. A first spring 406 is symmetrically installed on the side of the movable plate 403 near the hemispherical pressure block 405. One end of the first spring 406 is fixedly connected to the inner wall of the end of the electrical control box 402. Two first contacts 407 are symmetrically installed on the side of the movable plate 403 away from the hemispherical pressure block 405. Electrically connected, the control box 402 has symmetrically installed second contacts 408 on the inner wall of the side away from the hemispherical pressure block 405. The number of control boxes 402 is the same as the number of water pumps in the water pump unit. The control box 402 corresponds to the water pump one by one, and the corresponding water pump and power supply are connected in series between the two second contacts 408. The control boxes 402 are set at equal angles on the ring frame 401. The control box 402 corresponds to the water pump on the water pump unit one by one. By rotating the rotating block 501, the movable plate 403 inside the control box 402 is moved in sequence, so that the first contact 407 and the second contact 408 are in contact, and the corresponding water pump is started. This enables the automatic rotation and starting of multiple water pumps in a cycle, which is convenient to use. The inner side of the ring frame 401 is provided with a pressure start assembly 5.

[0020] The pressure-activated start assembly 5 includes a rotating block 501 coaxially disposed inside the ring frame 401. A rotating shaft 502 is coaxially mounted on one side of the rotating block 501. The rotating shaft 502 is rotatably connected to the back plate of the cabinet 1. A telescopic pressure component 503 is provided on the rotating block 501. A gear ring 505 is fixedly mounted on the side of the rotating block 501 near the rotating shaft 502. A gear 506 is meshed on the inner side of the gear ring 505 to control the number of rotations of the gear 506 in a single cycle, thereby facilitating the start-up of the water pumps on the pump unit that automatically cycle and rotate. The control is as follows: if there are six water pumps on the pump unit, the number of water pumps that can be started in rotation can be set to six, three, or two. This allows for control of the number of water pumps that can be started in rotation when the rotating block 501 rotates at the same angle in a single rotation. The gear 506 is fixedly connected to the output shaft of the first motor 507, which is installed inside the cabinet 1. The gear 506 is meshed with the gear ring 505 on one side of the rotating block 501, so that the corresponding water pump can be automatically started by rotating the rotating block 501. The telescopic pressing component 503 includes a circumferential box 5032 fixedly installed around the rotating block 501. A pressing plate 5033 is slidably installed inside the circumferential box 5032. The pressing plate 5033 has a raised arc surface at one end away from the rotating block 501. A first groove 5034 is provided on the side of the circumferential box 5032 away from the rotating shaft 502. The pressing plate 5033 is slidably connected to the first groove 5034. A fixed cylinder 5031 is coaxially installed on the side of the rotating block 501 away from the rotating shaft 502. One end of the fixed cylinder 5031 has an end contact 504. A second groove 5035 is provided at the top of the fixed cylinder 5031. An inner plate 5036 is movably installed inside the fixed cylinder 5031. A first connecting rod 5037 is hinged to the top of the inner plate 5036. One end of the first connecting rod 5037 is connected to the pressing plate 5033. The plate 5033 is hinged, and a second spring 5038 is fixedly installed on the side of the inner plate 5036 near the rotating block 501. One end of the second spring 5038 is fixedly connected to the inner wall of the end of the fixed cylinder 5031. A magnetic block 5039 is fixedly installed on the side of the inner plate 5036 away from the rotating block 501. An electromagnet 50310 is fixedly installed on the inner wall of the end of the fixed cylinder 5031 away from the rotating block 501. The electromagnet 50310 generates a repulsive force on the magnetic block 5039, driving the inner plate 5036 to move towards the rotating block 501, thereby pushing the pressing plate 5033 to move away from the rotating block 501. When the rotating block 501 rotates, the pressing plate 5033 can generate pressure on the hemispherical pressure block 405, realizing the contact between the first contact 407 and the second contact 408, which facilitates the start control of the water pump. The end contact component 504 includes an end post 5041 coaxially mounted on the end of the fixed cylinder 5031 away from the rotating block 501. An electrical control component 6 is provided on the outside of the end post 5041. Two third contacts 5042 are installed at the top of the end post 5041. Guide grooves 5043 are symmetrically opened on both sides of the end post 5041. The two third contacts 5042 are electrically connected to the positive and negative poles of the electromagnet 50310, respectively.

[0021] The power connection control assembly 6 includes two contact conductive elements 601 sleeved on the outside of the end post 5041. The two contact conductive elements 601 correspond one-to-one with two third contacts 5042. A power selection element 602 is provided on the outside of the end post 5041. The contact conductive component 601 includes an annular sleeve 6011 sleeved outside the end post 5041. Conductive arc plates 6012 are provided at equal angles on the inner side of the annular sleeve 6011. The number of conductive arc plates 6012 is the same as the number of water pumps in the water pump unit. Transverse grooves 6013 are provided at equal angles on the inner wall of the annular sleeve 6011. A transverse block 6014 is fixedly installed on the side of the conductive arc plate 6012 near the annular sleeve 6011. The transverse block 6014 is slidably connected to the transverse groove 6013. Third springs 6015 are symmetrically installed on both sides of the transverse block 6014. The ends of the two third springs 6015 are fixedly connected to the inner walls of the two ends of the transverse groove 6013, respectively. The power selection component 602 includes two first movable rings 6021 and two second movable rings 6023 sleeved outside the end post 5041. The two first movable rings 6021 are symmetrically arranged on the side of the two annular sleeves 6011 that are close to each other, and the two second movable rings 6023 are symmetrically arranged on the side of the two annular sleeves 6011 that are far apart from each other. Both the first movable rings 6021 and the second movable rings 6023 are slidably connected to the guide groove 5043. A first push rod 6022 is installed on the side of the two first movable rings 6021 that is far apart from each other. 3. Two push rods 6024 are installed on the sides of the two horizontal plates 6025 close to each other. Horizontal plates 6025 are installed on both the upper and lower sides of the end column 5041. Second connecting rods 6026 are symmetrically hinged on the side of the horizontal plates 6025 closest to the end column 5041. Two second connecting rods 6026 connected to the upper horizontal plate 6025 are hinged to two first moving rings 6021, and two second connecting rods 6026 connected to the lower horizontal plate 6025 are hinged to two second moving rings 6023. Fixed boxes 6027 are installed on the sides of the two horizontal plates 6025 furthest from each other. An internal block 6028 is slidably installed inside the fixed box 6027. Connecting rods 6029 are symmetrically installed between the internal block 6028 and the horizontal plate 6025. A screw 60210 is rotatably installed inside the fixed box 6027. The screw 60210 is threadedly connected to the internal block 6028. One end of the screw 60210 is fixedly connected to the output shaft of the second motor 60211. The second motor 60211 is fixedly installed on the fixed box 6027. A first push rod 6022 is provided on the first moving ring 6021, and a second push rod 6023 is provided on the second moving ring 6023. 024, the number of the first push rod 6022 is different from the number of the second push rod 6024. When controlling the movement of the two first moving rings 6021 or the two second moving rings 6023, the conductive arc plate 6012 can be pushed to move to a position offset from the third contact 5042. When the pressure plate 5033 on the rotating block 501 rotates to the position corresponding to the electrical control box 402 of the water pump that is not in use, the electromagnet 50310 is in a de-energized state, so that the pressure plate 5033 moves back into the circumferential box 5032, ensuring that the water pump that is not in use will not be started. The cabinet 1 is equipped with a fixed frame, and two ring sleeves 6011 and two fixed boxes 6027 are fixedly installed on the fixed frame.

[0022] Working principle: In this application, the water pump unit is equipped with six water pumps, so that there are six electrical control boxes 402 on the ring frame 401 and six conductive arc plates 6012 on the ring sleeve 6011. The top electrical control box 402 controls water pump A, and along the ring frame 401 clockwise, the other electrical control boxes 402 control water pumps B, C, D, E, and F respectively. The conductive arc plates 6012 inside the two annular sleeves 6011 are electrically connected to wires. The wires connected to each conductive arc plate 6012 on one annular sleeve 6011 are connected to the positive terminal of the power supply, and the wires connected to each conductive arc plate 6012 on the other annular sleeve 6011 are connected to the negative terminal of the power supply. A main switch is provided in the circuit. When six water pumps need to be started automatically in sequence, the main switch is turned on. At this time, the two third contacts 5042 contact the conductive arc plates 6012 on the two annular sleeves 6011, so that the electromagnet 50310 is in a continuously energized state. This causes the electromagnet 50310 to generate a repulsive force on the magnetic block 5039, pushing the internal plate 5036 to move towards the rotating block 501. Then, through the first connecting rod 5037, the pressing plate 5033 is pushed to move outward along the circumferential box 5032, pushing the top hemispherical pressure block 405 to move upward. This causes the movable plate 403 in the top electrical control box 402 to move, so that the two first contacts 407 contact the two second contacts 5042. Contact 408 makes contact, thereby connecting the external circuit of water pump A and starting water pump A. When water pump B needs to be started, the first motor 507 is turned on, driving gear 506 to rotate. Gear 506 meshes with gear ring 505, thereby driving rotating block 501 to rotate, causing pressure plate 5033 to rotate to the position corresponding to the adjacent clockwise electrical control box 402, thereby starting water pump B. This process is repeated. By rotating block 501, and because electrical control box 402 is set at equal angles on the circumference of ring frame 401, water pumps A, B, C, D, E, and F can be automatically and cyclically started in turn. The first motor 507 controls the gear 506 to rotate one revolution, which drives the rotating block 501 to rotate one-sixth revolution. The controller 3 controls the number of revolutions of the gear 506 in a single cycle of the first motor 507, thereby controlling the rotation angle of the rotating block 501 in a single cycle. For example, if the gear 506 rotates twice in a single cycle, the rotating block 501 rotates one-third revolution, thereby controlling the number of times the water pump is started in a cycle. The controller 3 also controls the start-up time of the first motor 507 between two consecutive starts, thereby controlling the start-up time of a single water pump. Since there are six water pumps, the number of water pumps used can be controlled to be six, three, or two during automatic rotation start-up. When the number of water pumps starting in rotation is six, the number of rotations of the control gear 506 in a single cycle is one. When three water pumps are started in rotation, the control gear 506 rotates twice in a single cycle. During this rotation, the second motor 60211 above is activated, driving the upper horizontal plate 6025 downwards. This, in turn, pushes the two first moving rings 6021 away from each other via two second connecting rods 6026. Three first push rods 6022 are evenly spaced on the first push rod 6022, enabling the movement of the three conductive arc plates 6012. This ensures that during one revolution of the end post 5041, the third contact point 5042 only contacts the three stationary conductive arc plates 6012. When the third contact point 5042 contacts the three stationary conductive arc plates 6012... When contact is made, the movable plates 403 on the three electrical control boxes 402 corresponding to pumps A, C, and E are moved respectively, so that pumps A, C, and E can be started in a cycle automatically. When the third contact 5042 moves to the position corresponding to pumps B, D, and F, since the third contact 5042 is not in contact with the conductive arc plate 6012 at this time, the electromagnet 50310 is in a de-energized state, so the pressure plate 5033 moves back into the circumferential box 5032 and does not push the movable plates 403 in the corresponding electrical control boxes 402 to move, ensuring that pumps B, D, and F are always in a de-energized state. When two water pumps are started alternately, the control gear 506 rotates three times in a single cycle. This activates the lower second motor 60211, driving the lower horizontal plate 6025 upwards. Two second connecting rods 6026 push the two second moving rings 6023 closer together. Four first push rods 6022 are mounted on the first push rod 6022, which in turn pushes the four conductive arc plates 6012 to move, leaving only the upper and lower conductive arc plates 6012 in their original positions. This ensures that during one revolution of the end column 5041, the third contact point 5042 only contacts the two stationary conductive arc plates 6012. When the third contact point 5042 contacts the stationary conductive arc plates... When the two conductive arc plates 6012 come into contact, they respectively push the movable plates 403 on the two electrical control boxes 402 corresponding to water pumps A and D to move, so that water pumps A and D can automatically take turns starting. When the third contact 5042 moves to the position corresponding to water pumps B, C, E, and F, since the third contact 5042 is not in contact with the conductive arc plate 6012 at this time, the electromagnet 50310 is in a de-energized state, so the pressure plate 5033 moves back into the circumferential box 5032 and does not push the movable plate 403 in the corresponding electrical control box 402 to move, ensuring that water pumps B, C, E, and F are always in a de-energized state.
