Description

Technical Field

[0001] The utility model relates to the technical field of water inlet pipe structures, and more specifically, to a water inlet pipe structure based on a water pump. Background Art

[0002] A water pump is a device used to transport liquids, usually driven mechanically or electrically. The water inlet pipe structure based on the water pump is a pipe system connected to the water pump. These pipes ensure that the water pump can effectively absorb and transport liquids while ensuring the stable operation and safety of the system. However, it still has some shortcomings in actual use, such as: after the water pump stops running, the water in the water inlet pipe is inconvenient to discharge, and part of the water will remain in the water inlet pipe. In a low temperature environment, this water will freeze and expand, which can easily cause the water inlet pipe to rupture, causing damage and leakage.

[0003] Therefore, a water inlet pipe structure based on a water pump is proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a water inlet pipe structure based on a water pump, so as to solve the problem in the prior art that after the water pump stops running, the water in the water inlet pipe of the water pump is inconvenient to be discharged, and part of the water will remain in the water inlet pipe. In a low temperature environment, the water will freeze and expand, thereby easily causing the water inlet pipe to rupture, resulting in damage and leakage of the water inlet pipe.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a water inlet pipe structure based on a water pump, comprising a water inlet pipe body, a water stop assembly is arranged inside the water inlet pipe body, a drainage assembly is arranged at the bottom of the water inlet pipe body, and a water pump inlet pipe joint, an SCR return water joint, and an EGR cooler outlet water joint are arranged horizontally and fixedly connected in sequence at the top of the water inlet pipe body;

[0006] The water stop assembly includes a rotating handle, the middle part of which is rotatably connected to the inside of the water inlet pipe body, the bottom end of which is fixedly connected to a ball valve, both sides of which are slidably connected to friction blocks, which are fixedly installed inside the water inlet pipe body, and a heating ring is fixedly connected to the side of the friction block away from the ball valve;

[0007] The drainage assembly includes a drainage pipe, the top end of the drainage pipe is fixedly connected to the bottom of the water inlet pipe body, a fixing plate is fixedly installed inside the water inlet pipe body, a controller is fixedly installed at the bottom of the fixing plate, an electromagnet is fixedly connected to the bottom of the controller, a sliding rod is slidably connected to the bottom of the drainage pipe, a cover plate is fixedly connected to the bottom end of the sliding rod, and a metal block is fixedly installed on the top of the cover plate.

[0008] The ball valve is provided with a through hole for water to flow through, and the friction block is made of a heat-conducting material for absorbing and transferring the heat generated by the heating ring.

[0009] Among them, it also includes a control terminal, which is electrically connected to the heating ring and the controller, and is used to control the start and stop of the heating ring and the electromagnet.

[0010] It also includes threads, which are respectively opened inside the water pump inlet pipe joint, the SCR return water joint, and the EGR cooler outlet water joint, and a sealing ring is fixedly installed on the top of the thread.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] In the above scheme, a water inlet pipe body, a water stop assembly, a drainage assembly, a control terminal, a water pump inlet pipe joint, an SCR return water joint, and an EGR cooler outlet joint are provided. When the temperature is too low, the ball valve is rotated in the friction block by turning the handle, and the ball valve closes the water inlet end of the water inlet pipe body. A signal is sent to the controller through the control terminal, and then the controller controls the electromagnet to eliminate the magnetic force. At this time, the cover plate and the metal block drive the sliding rod to slide downward from the drainage pipe under the action of gravity, so that the water in the water inlet pipe body flows out from the gap. Through the above structure, the water in the water inlet pipe body can be drained when the temperature is too low, so as to prevent the water in the water inlet pipe body from freezing and causing the water in the water inlet pipe body to rupture.

[0013] Set threads and sealing rings, screw the threaded connector into the water pump inlet pipe connector, the SCR return water connector, and the EGR cooler outlet connector, and use thread glue to quickly assemble the water inlet pipe body with the water pump. Because the thread glue and thread properties can play a good sealing and fixing role, when assembling connectors of existing products, the water pump inlet pipe is mostly assembled with a bare hole, and the connector needs to be pressed in with a press. When the press is pressed in, it is easy to cause the pipe body to crack. Through the above structure, when using the thread shape to screw in, it can save time and effort, and it is also more convenient to replace parts later. BRIEF DESCRIPTION OF THE DRAWINGS
