[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. A controller installed on the water pump can control the start and stop, speed, and forward and reverse rotation of the motor in the water pump. Conventional controllers are placed above the motor or on one side of the motor, and a controller box is set to cover the controller to prevent water from leaking into the motor or onto the controller, thereby damaging the controller.

[0008] Its working principle is as follows: in this technical solution, the motor is electrically connected to the controller, and the controller can control the start and stop, forward and reverse rotation and speed of the motor. The controller is inverted in the installation groove of the base to separate the controller from external water. Here, the existing base is used to protect the controller, which not only simplifies the installation structure of the controller, but also reduces the production cost of the water pump. The controller can be grounded through the base to improve safety performance; the base and the motor are sealed to prevent external water from seeping in; the cable electrically connected to the motor and the controller passes through two wire holes and enclosures, so that the position of the cable at the end of the enclosure is the lowest point of the cable. When the water pump is working, condensed water generated by high temperature can drip on the cable here, which can avoid contact between the condensed water and the controller; the cover shell is set to prevent external water from entering the installation groove, and a through hole is set on the base for the lead wire that electrically connects the controller to other external components to pass through, and there is a gap between the lead wire and the through hole, so that the through hole can be used as a wire hole and for the water in the installation groove to flow out, effectively preventing the water on the upper side of the cover in the installation groove from contacting the controller, thereby improving the stability of the controller.

[0009] In the above-mentioned installation structure of the water pump controller, the base has a protruding portion, the installation groove is provided in the protruding portion, the lower side of the base has a water channel communicating with the installation groove, and the cover is located in the water channel and connected to the notch of the installation groove.

The controller dissipates heat by means of the heat-conducting columns and the fixing bolts to prevent the water pump from shutting down due to excessive internal temperature during operation.

[0015] In the above-mentioned installation structure of the water pump controller, the heat-conducting column is made of metal material, and the position of the end of the heat-conducting column on the base is higher than the position of the through hole and the water outlet hole on the base. The metal material of the heat-conducting column helps the controller to dissipate heat quickly.

[0016] In the above-mentioned installation structure of the water pump controller, a plurality of water holes communicating with the water trough are opened on the upper side of the base, and the positions of the water holes on the base are all lower than the positions of the through holes and the water outlet holes on the base, so that the water on the base and the water discharged from the through holes or the water outlet holes in the installation trough can flow out of the water pump.

[0017] In the above-mentioned installation structure of the water pump controller, a groove is provided near the edge of the upper side of the base for the lower side of the water pump housing to be embedded in. The water pump housing is provided to prevent external liquid from flowing back into the water pump.
