Description

TECHNICAL FIELD

[0001] The utility model relates to the field of construction equipment, especially to a cooling water anti-freezing device for construction equipment in cold environment. BACKGROUND

[0002] The anti-freezing problem of cooling water mainly occurs in cold seasons. The cooling system is crucial for the normal operation of many equipment and machines, so measures need to be taken to prevent the cooling water from freezing. Traditional anti-freezing methods: the traditional cooling water anti-freezing method mainly includes three kinds. One is to add antifreeze, such as ethylene glycol, propylene glycol, and other organic solvents. These solvents can lower the freezing point of the coolant and prevent the coolant from freezing. Another is to use a heat exchanger to prevent the coolant from freezing by heat exchange with the external environment, such as using air source, water source, etc. The second is a heat conduction anti-freezing device: this type of anti-freezing device covers a layer of material with good heat conductivity on the outside, allowing heat to quickly transfer from the material surface to the cooling water, thereby preventing the cooling water from freezing. Common materials include metal, plastic, composite materials, etc.

[0003] After searching, the Chinese invention patent with the authorization announcement number CN 104101081 A discloses a cooling water anti-freezing device for construction equipment in cold environment and an anti-freezing method, which includes a water supply package and a heating device.

[0004] The above device has at least the following technical problems:

[0005] 1. The heating device in the water supply package heats the incoming water, which flows out after being heated. This method is difficult to heat the flowing water to the required temperature in actual operation, and the water will lose a lot of heat when it contacts the external environment during transportation, which can easily cause the water to freeze before it reaches the destination, affecting the normal construction of the construction site. In addition, it is difficult to control the water temperature in actual operation. Once the above-mentioned water freezes in the water pipe during transportation, the water pipe needs to be replaced and the water source needs to be transported again, which will affect the construction progress.

[0006] 2. For extreme cold temperatures in the north, the cooling water tower may sometimes have completely frozen internal cooling water, and the above device cannot solve the water problem of construction.

[0007] In view of the above technical problems, it is necessary to propose an improved cooling water anti-freezing device for construction equipment in cold environment. UTILITY MODEL CONTENTS

[0031] The bottom end of the cooling water tower 2 is uniformly fixedly connected with at least three supporting columns 11, and the bottom end of the supporting column 11 is in contact with the inner wall of the protective shell 1.

[0032] The heating mechanism is a heating wire installed at the bottom of the heating cavity, and the heating wire is electrically connected with an external power supply.

[0033] The top end of the cooling water tower 2 is provided with water inlet 14, the water inlet pipe 9 is threadedly connected to the inner wall of the water inlet 14, the top end of the cooling water tower 2 is provided with circulation port 15 at a position other than the center, and the inner walls of the circulation port 15 and the air hole 16 are respectively provided with sealing heads 10.

[0035] The working principle of this device is as follows: In actual use, cooling water is first injected into the cooling tower 2. After the cooling water is injected, part of it is in the water storage cavity at the top of the conical plate 17, and part of it flows into the heating cavity through the through hole 18.
