Description

Technical Field

[0001] This utility model relates to the field of pump start-stop controllers, and more specifically to a pump start-stop controller. Background Technology

[0002] Water pumps are widely used as core equipment for fluid transport in various scenarios such as agricultural irrigation, industrial fluid transportation, and household water supply and drainage systems. These devices typically rely on external power supply. Currently, water pumps are generally powered by a plug directly inserted into an external socket. This method is popular due to its ease of operation and lack of complex installation procedures. However, water pumps often operate in specific environments, characterized by splashing water and high humidity. Existing water pump start / stop controllers are not suitable for providing a concealed power supply, which is safer than plugging the power cord into a socket, preventing short circuits caused by water splashing into the socket during operation. Therefore, this application is proposed to address these technical issues. Utility Model Content

Detailed Implementation

[0011] A pump start / stop controller includes a pump body and two conduits 401. The bottom of one conduit 401 is fixedly connected to the pump body. A long frame 402 is fixedly connected between the two conduits 401. Each conduit 401 is equipped with an electric wire. A contact plate 403 is fixedly connected to one side of each electric wire inside the long frame 402. A crossbar 301 is rotatably connected to the middle of the long frame 402. A conductive plate 303 is fixedly connected to the front side of the crossbar 301, and a gear 302 is fixedly connected to the rear side of the crossbar 301.

[0012] This section is based on Figures 1-10The embodiment described herein is as follows: To facilitate the provision of a concealed power supply circuit water pump start / stop controller, which is safer than supplying power through a plug inserted into a socket, preventing water from spraying into the socket during water pump operation and causing a short circuit in the water pump plug, two conduits 401 are provided. The two conduits 401 are made of PVC insulated pipe material, allowing the wires to extend into them. The two conduits 401 are bolted to the upper and lower sides of a long frame 402, respectively, with a contact plate 403 bolted to the wire ports inside each conduit 401. The contact plates 403 are located within the upper and lower sides of the long frame 402. A crossbar 301 is rotatably connected to the middle of the long frame 402. The front end of the crossbar 301 is located within the long frame 402, and a conductive plate 303 is fixedly installed at the front end by bolts. A rubber pad is placed between the conductive plate 303 and the crossbar 301, and the crossbar 301 can be made of insulating plastic. When the water pump needs to be started or stopped, the crossbar 301 is rotated, causing the conductive plate 303 to rotate. Simultaneously, the two ends of the conductive plate 303 contact the conductive plates 303 on the two wires respectively, forming a power flow and driving the water pump to start or stop. This facilitates the provision of a water pump start / stop controller with a hidden power supply line, which is safer than supplying power by inserting a power plug into a socket. It prevents water from spraying into the socket during water pump operation and causing a short circuit in the water pump plug. When the wire is located in the conduit 401, it effectively protects the wire and prevents wear and tear on the wire during operation.

[0013] A groove is provided on each opposite side of both ends of the conductive sheet 303. This part is based on... Figures 1-10 The embodiment described herein is as follows: a groove is processed on the opposite side of each end of each conductive sheet 303, so that when the conductive sheet 303 rotates and its two ends come into contact with the corresponding contact sheet 403, the contact sheet 403 can be embedded into the groove on one end of the corresponding conductive sheet 303, which helps to stabilize the contact between the two ends of the conductive sheet 303 and the contact sheet 403.

[0014] Two 401 cable conduits are installed vertically. This section is based on... Figures 1-10 The embodiment described herein is such that the two conduits 401 are arranged vertically, so that the wires extend upwards to connect with the power source at a higher position, and prevent the wires from being coiled around the pump body.

[0015] The pump body includes a base 101 and a motor 102 fixedly connected to the base 101. A conveying frame 103 is fixedly installed on the rear side of the base 101. An inlet pipe 105 is fixedly connected to the upper right side of the conveying frame 103, and an outlet pipe 104 is fixedly connected to the lower left side of the conveying frame 103. A power rod is fixedly connected to the output shaft of the motor 102. The rear side of the power rod extends into the conveying frame 103, and an impeller 108 is fixedly connected to the rear end of the power rod.

[0016] This section is based on Figures 1-10 The embodiment described herein is as follows: When the pump body is in use, when the power supply is connected and the conductive sheet 303 is in contact with the electrical contacts 403 on both sides to conduct electricity, the power rod on the motor 102 rotates, and the impeller 108 on the power rod rotates in the conveying frame 103, thereby using the water inlet pipe 105 to introduce water and the water outlet pipe 104 at the bottom to flow out, thus completing the water extraction work of the water pump.

[0017] A flange is fixedly connected to the inlet of both the outlet pipe 104 and the inlet pipe 105. This section is based on... Figures 1-10 The embodiment described herein is as follows: a flange is fixedly connected to the outlet pipe 104 and the inlet pipe 105 by bolts, which facilitates the flow of water through other pipes.

[0018] A connecting frame 106 is fixed and connected to the middle of the water inlet pipe 105. A sliding plate 201 is slidably connected inside the connecting frame 106, and a flow port is provided on the lower side of the sliding plate 201. A right-angle bracket 107 is fixedly connected to the middle right side of the base 101, and the middle part of the crossbar 301 is rotatably connected to the right-angle bracket 107. A rack plate 202 is fixedly connected to the upper side of the sliding plate 201, and multiple teeth are evenly provided on the left side surface of the rack plate 202. The rack plate 202 engages with the gear 302 through the multiple teeth on its left side surface. A handle 203 is fixedly connected to the right side of the rack plate 202.

[0019] This section is based on Figures 1-10The embodiment described herein is as follows: Initially, the flow port on the sliding plate 201 is located below the connecting frame 106, and the conductive sheet 303 is not in contact with the contact sheets 403 on both sides. That is, the position above the flow port of the sliding plate 201 is blocked from the water inlet pipe 105. When the pump body is energized to circulate water, the user grasps the handle located on the rack plate 202 and pulls the sliding plate 201 upward. At this time, the rack plate 202 above the sliding plate 201 and the toothed rod behind the crossbar 301... The gear 302 engages in a meshing transmission, causing the gear 302 to rotate. The crossbar 301 located in the middle of the gear 302 rotates on the right-angle bracket 107. The conductive plate 303 in front of the crossbar 301 rotates synchronously, causing the two sides of the conductive plate 303 to contact and adhere to the two contact plates 403 to energize the motor 102. Conversely, when the energization is deactivated, the operation is reversed. This helps to block the water inlet pipe 105 above the sliding plate 201 while energizing, preventing excess water from flowing out after the water flow is deactivated.
