[0033] This utility model provides a crane energy recovery and utilization device, including: a water tank device 1;

[0034] An electrical device 2 is installed in the crane's electrical control room; the electrical device 2 includes an air conditioner; a first pipeline assembly 3 connecting the water tank device 1 and the water outlet of the electrical device 2; the first pipeline assembly 3 is used to guide the condensate generated by the electrical device 2 to the water tank device 1; a resistor 4 is used to transfer heat to the water tank device 1; the water tank device 1 is attached to the outside of the resistor 4. In this utility model, by connecting the useless condensate discharged from the air conditioner in the crane's electrical control room to a water tank located outside the resistor, and heating the water with the heat energy generated when the resistor is working, the heated water can be used for daily maintenance, cleaning, and other work of the crane equipment. While saving resource costs, it can avoid the technical problem of condensate dripping on the outside of the equipment for a long time, which would damage the anti-corrosion layer of the equipment and affect the life of the equipment. It also solves the problem of poor personnel comfort caused by excessive temperature in various mechanisms of the crane. In addition, this utility model also relates to a crane control system, including the crane energy recovery and utilization device as described above, which also has the above-mentioned technical effects.

[0035] Specifically, in a specific embodiment of this utility model, the water tank device 1 includes: a main water tank 101; and a water tank assembly 103 connected to the main water tank 101 via a second pipeline assembly 102.

[0036] Specifically, in a specific embodiment of this utility model, the main water tank 101 includes:

[0037] Water tank body; installed at the lower part of the water tank body for connecting to the discharge interface structure 105 at the user end.

[0038] Specifically, in a specific embodiment of this utility model, the main water tank 101 further includes:

[0039] The water level height discharge port structure 106 is installed on the upper part of the water tank body.

[0040] Specifically, in a specific embodiment of this utility model, it further includes: a temperature sensor 5 disposed on the water tank body.

[0041] Specifically, in a specific embodiment of this utility model, it further includes a flow meter 6 installed at the discharge interface structure 105.

[0042] Specifically, in a specific embodiment of this utility model, the water tank assembly includes a water tank structure connected through a second pipeline assembly 102.

[0043] More specifically, in specific embodiments of this utility model, the number of water tank structures is 2 to 24.

[0044] Specifically, in a specific embodiment of this utility model, the water tank device 1 is made of stainless steel or copper.

[0045] In this embodiment, the water tank device 1 is preferably made of a material with high thermal conductivity. The heat energy generated by the resistor is transferred to the water tank and heats the water inside the water tank. In this way, the water in the water tank can be used efficiently for daily maintenance, cleaning and other work of the equipment, realizing the recycling of resources while avoiding the outflow of condensate water, which would cause damage to the surface of the equipment and affect the service life of the equipment.

[0046] Specifically, in a specific embodiment of this utility model, it further includes: a heat insulation layer structure disposed on the outside of the water tank device 1.

[0047] In addition, this utility model embodiment also provides a crane control system, including the crane energy recovery and utilization device as described above, which also has the above-mentioned technical effects.

[0048] To elaborate more specifically, the energy generated by the inertial potential energy during braking of various working mechanisms on a crane is currently mostly consumed by heating through resistors. This energy is not being properly recovered and utilized in existing technologies, but is instead directly wasted. Furthermore, the resistors of each mechanism are generally located near the mechanism or inside the building where the mechanism is located. The high heat generated by the resistors also leads to an increase in the overall temperature of the building, affecting the normal operation and lifespan of other equipment and components inside the building. It also affects the comfort of operators or maintenance personnel working in this area, which is particularly noticeable in summer.

[0049] The crane energy recovery and utilization device involved in this utility model embodiment mainly addresses the problem of energy waste during braking of various mechanisms of the crane and the impact on the comfort of components, related equipment, and personnel in each mechanism area. It provides an energy recovery device that can recover and utilize energy during braking of various working mechanisms of the crane and improve the temperature of the working area of ​​each mechanism.

[0050] Specifically, the energy recovery and utilization device involved in this utility model embodiment consists of an air conditioner installed in the electrical control room, a resistor for consuming the inertial energy during braking of each mechanism, a water tank installed outside the resistor, and pipelines connecting the water outlet of the air conditioner to the water tank and the interconnections between the water tanks.

[0051] The condensate discharged from the air conditioner in the crane's electrical control room or operator's room is transported through pipelines to a water tank located outside the resistor. The water tank is attached to the outside of the resistor and is preferably made of materials with high thermal conductivity, such as stainless steel or copper. The heat generated by the resistor is transferred to the water tank to heat the water inside. The water in the tank can be used for routine maintenance and cleaning of the equipment.

[0052] The water tanks outside the resistor are interconnected by pipes, and the water level and temperature inside are kept consistent. A discharge port for connecting to the user is set at the bottom of the water tank, and a water level discharge port is set at the top.

[0053] In summary, the energy recovery and utilization device involved in this utility model embodiment connects the useless condensate discharged from the air conditioner in the crane's electrical control room to a water tank located outside the resistor, and uses the heat energy generated when the resistor is working to heat the water, which can be used for the daily maintenance and cleaning of the crane equipment.

[0054] The crane's electrical room houses numerous electrical control devices and serves as the control center for the entire crane. To ensure the normal operation of the control center, there are usually at least two air conditioners in the room, each with a power rating of 3P or higher. Previously, the large amounts of condensate discharged from these air conditioners were simply dumped directly onto the ground as wastewater. This waste not only resulted in water dripping onto the equipment's surface for extended periods, but also caused damage to the localized anti-corrosion coating, impacting the equipment's lifespan. This new device saves water resources by collecting the discharged water, reducing the long-term dripping onto the equipment and thus contributing to its corrosion resistance and lifespan.

[0055] Furthermore, the water tank installed outside the resistor can fully collect the useless heat energy generated by the resistor and heat the condensate discharged from the air conditioner, which has a significant beneficial effect on heat energy collection and utilization.

[0056] Meanwhile, during equipment maintenance and cleaning, personnel no longer need to carry water from below the crane to the top; they can directly use the heated condensate from the water tank, which is convenient, saves time, and reduces the labor intensity of personnel. Furthermore, using hot water for equipment maintenance and cleaning also offers advantages such as high efficiency, good performance, and improved operator comfort, especially in winter.

[0057] Furthermore, because the heat generated by the resistor is absorbed by the water in the tank, the temperature inside the crane's electrical control room will be significantly reduced, which will have a positive effect on the lifespan of related equipment and components on the crane, as well as the comfort of the operators and maintenance personnel.

[0058] Therefore, this energy recovery and utilization device has a simple structure, low cost, and obvious effect. It does not require a dedicated external power source and has substantial features, technological advancements, and high application value compared with existing technologies.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
