Description

Technical Field

[0001] The utility model relates to the technical field of water pump controllers, in particular to a water pump controller which is convenient for maintenance. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. The water pump controller is an electronic instrument installed on the water pump to control the water pumping volume and the power on and off of the water pump.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN219220758U discloses a water pump controller that is easy to load and unload. The device fixes the controller body by means of a micro ball screw and a fixed sleeve. However, if a large number of water pumps need to be repaired, the micro ball screw needs to be rotated frequently, so that the micro ball screw drives the fixed sleeve to pull out the plug-in rod, which results in a long maintenance time for workers and reduces work efficiency. In view of this, we propose a water pump controller that is easy to repair. Utility Model Content

[0004] The main purpose of the utility model is to provide a water pump controller that is easy to maintain and can solve the problems raised in the above technical background.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a water pump controller that is convenient for maintenance, including a device body, and a control system is arranged on the upper surface of the device body, and the control system includes:

[0006] The shell is provided with two guide protrusions on the surface of the shell, so that when workers install the controller, the guide protrusions can guide and limit the controller, thereby facilitating the installation of the workers. The inner wall of the shell is fixedly connected with a transmission interface, the surface of the shell is hinged to the inner wall of the cover plate, and the back of the cover plate is fixedly connected with an arc rod, and the surface of the arc rod is slidably connected to the inner wall of the shell.

[0007] Preferably, a connector is rotatably connected to the front surface of the shell, and a clamping plate is rotatably connected to the inner wall of the shell.

[0008] Preferably, a pressure rod is slidably connected to the inner wall of the shell, an end face of the pressure rod is fixedly connected to one side of the connecting plate, and the other side of the connecting plate is fixedly connected to the end face of the center rod.

[0009] Preferably, the upper surface of the connecting plate is fixedly connected to one end of the spring sheet, and the other end of the spring sheet is fixedly connected to the inner wall of the outer shell.

[0010] Preferably, a recessed support is rotatably connected to the surface of the center rod, and a push rod is fixedly connected to the surface of the center rod.

[0011] Preferably, the device body comprises a connection port, a surface of the connection port is fixedly connected to a surface of a base plate, and a pump is fixedly connected to the front side of the base plate.

[0012] Preferably, a recessed support is fixedly connected to the inner wall of the shell, and a controller is slidably connected to the surface of the shell.

[0013] The utility model provides a water pump controller that is easy to repair and has the following beneficial effects:

[0014] (1) The water pump controller which is convenient for maintenance has an arc-shaped rod. When the controller needs to be taken out and locked, the cover is closed and the connector is rotated so that the connector fixes the cover. The arc-shaped rod on the cover slides into the shell, thereby squeezing one end of the pressure rod, so that the other end of the pressure rod drives the connecting plate to move downward, thereby causing the center rod to rotate. The push rod pushes up the card plate, so that the card plate is inserted into the bottom of the controller to fix the controller, so that the interface of the controller is always closely connected with the transmission interface, thereby making the controller more stable when working and making it more convenient to take out the controller during maintenance, thereby improving the maintenance work efficiency.

[0015] (2) The water pump controller that is easy to maintain can be directly removed from the control system during maintenance through the transmission interface, making the maintenance of the controller more convenient. There is no need to move large instruments to the vicinity of the water pump, but the smaller controller can be directly taken away for easy inspection. BRIEF DESCRIPTION OF THE DRAWINGS
