Drainage device of water tank, water tank having drainage device and pumping equipment

Abstract

The invention provides a drainage device of a water tank, a water tank having drainage device and pumping equipment. The drainage device of water tank comprises a pull rod part arranged in the water tank and a sealing water block connected with the pull rod part, the pull rod part comprises a driving element rotatablely arranged in the water tank, the driving element comprises a connecting end used for driving the sealing water block to move to open or close the water outlet of the water tank and a driving end used for driving the connecting end to move, and the connecting end and the driving end are respectively located on the two ends of the driving element; and a slide bar, the first end of the slide bar is connected with the connecting end of the driving element, and the sealing water block is arranged on the second end of the slide bar. A water tank comprises the drainage device. The pumping equipment comprises a water tank, wherein the water tank is the above mentioned water tank. The sealing water block in the invention blocks the water outlet in the water tank, so that the water outlet would not be blocked or frozen, the water outlet can be effectively prevented from being blocked or frozen, and the structure is simple to facilitate the operation of workers.

Description

technical field [0001] The invention relates to the field of engineering machinery water cooling systems, and more specifically, to a water discharge device for a water tank, a water tank and pumping equipment with the water discharge device. Background technique [0002] Water tank 10' in the prior art mainly connects drain pipe 50' from water tank 10' front end face, and connects ball valve 60' at the end of drain pipe 50' to realize the water discharge switch function. However, since the water discharge switch, that is, the ball valve 60' is at the end of the water discharge pipe 50', the water outlet 40' and the water discharge pipe 50' are prone to freezing and blockage, which leads to the problem that the low temperature operation of the pumping equipment is blocked and the water cannot be released. Contents of the invention [0003] The invention provides a water discharge device of a water tank, a water tank and pumping equipment provided with the water discharge d...
