Description

Technical Field

[0001] The utility model relates to the technical field of water pump control equipment, in particular to a water pump control box for a heating pipe network. Background Art

[0002] The heating network is an important part of the heating system, which is responsible for delivering the heat energy of the heat source to the terminal equipment of each user. Water pumps are usually required in the heating network to increase the pressure and flow of water flow to ensure the efficiency and quality of heating. The operation and control of the water pump requires the corresponding control box, which contains the power supply, switch, protector, sensor and other components of the water pump, which is used to control and manage the start and stop, speed regulation, overload protection, fault detection and other functions of the water pump.

[0003] In the prior art, the shell of the water pump control box is usually fixed with bolts, which require tools to remove, are very inconvenient, and the disassembly speed is slow. In addition, the bolts are prone to stripping after repeated use, resulting in some bolts being unable to fix the shell.

[0004] The patent with publication number CN212479535U discloses a water pump intelligent controller shell that is easy to disassemble, including a water pump controller, a shell is arranged on the surface of the water pump controller, a connecting shaft is rotatably connected to the middle of the shell, a circular plate is fixedly connected to the end of the connecting shaft away from the shell, the circular plate is arranged inside the water pump controller, two limiting holes are relatively opened on both sides of the circular plate, limiting blocks are fixedly connected in the limiting holes, heat dissipation holes are opened on the surface of the shell and below the torsion block, and a dustproof net is fixedly connected to the heat dissipation hole. The beneficial effect is that when the shell of the water pump controller needs to be disassembled, the two handles are pulled so that the spring is compressed, and the two limiting blocks are separated from each other, so that the limiting blocks are separated from the limiting holes on the circular plate, and the torsion block is twisted to drive the circular plate to rotate, and the limiting holes on the circular plate are offset from the limiting blocks, and the shell can be pulled out. The disassembly is very convenient, no tools are required, and it is very fast. By setting the dustproof net, the dustproof net on the heat dissipation hole prevents dust from entering the inside of the shell.

[0005] When disassembling the outer shell of the above-mentioned prior art, it is necessary to pull the two handles at the same time so that the two limit blocks are respectively moved out from the two limit holes on the circular plate at the same time to release the positioning of the circular plate, and then the twist block needs to be twisted. This process cannot be completed by a single worker. The single worker needs to pull the two handles with both hands respectively, so that the twist block cannot be twisted, resulting in the need for two workers to complete the disassembly of the outer shell, increasing the investment in labor costs. In addition, the limit block, connecting block, sliding rod and spring are located in the middle of the controller shell, which takes up more space and affects the installation of components inside the water pump controller shell. In view of this, we propose a water pump control box for a heating pipe network. Utility Model Content
