Description

Technical Field

[0001] The invention relates to the field of port engineering, and in particular to a water supply device for loading and unloading equipment. Background Art

[0002] There are currently two ways to supply water on board bulk cargo terminals. One is water cable water supply, which uses a combination of water cables and water cable drums to supply water, similar to the onboard power supply method. The other is to use open water tanks to supply water, and pumping facilities are installed on the equipment to pump water from the tanks.

[0003] The water cable water supply method is only suitable for short-distance water supply conditions. The longer the equipment runs, the heavier the water cable is, the larger the water cable drum is, and the more difficult it is to implement the equipment. At present, the water supply distance of the water cable drum generally does not exceed 200m, which is difficult to achieve for bulk cargo storage or berths exceeding 200m. Antifreeze of water cables also requires certain technical treatment.

[0004] When using open water tanks for water supply, bulk cargo that is loaded, unloaded or stored is easy to fall into the water tank and cause siltation, and impurities in the water are also easy to damage the pumping equipment and spraying equipment. The antifreeze problem of open water tanks cannot be solved. Summary of the invention

[0005] The invention aims to solve the technical problems that the existing water cable has a short water supply distance, and bulk dust easily enters the water tank when supplying water through an open water tank, causing siltation, blocking the pumping equipment and damaging the spraying equipment.

[0006] In order to solve the above problems, the present invention provides a water supply device for loading and unloading equipment, including a water tank and a water intake pipe, wherein an η-shaped outlet channel is provided on one side of the water tank, and the opening of the η-shaped outlet channel faces downward, one end of the water intake pipe is inserted in the η-shaped outlet channel and extends to the bottom of the η-shaped outlet channel, and the other end of the water intake pipe is connected to the loading and unloading equipment.

[0007] Optionally, a sealing brush is provided between the opening of the η-shaped outlet channel and the water intake pipe.

[0008] Optionally, a water storage tank is provided on the other side of the water tank, and the bottom of the water storage tank is connected to the bottom of the η-shaped outlet channel.

[0009] Optionally, a heating pipe is provided in the water tank.

[0010] Optionally, a heat-insulating layer is provided outside the water tank.

[0011] Optionally, an openable and closable upper cover is provided on the top of the water tank.

[0012] Optionally, a high water level limit switch and a low water level limit switch are provided in the water tank.

[0013] Optionally, the water outlet of the water intake pipe is provided with a spray device.

[0014] The present invention adopts a water tank provided with an η-shaped outlet channel, the η-shaped outlet channel opens downward and presents a tortuous maze-like structure, so that bulk dust in the outside air is not easy to enter the interior, and even if a small amount of dust floats in from the opening of the η-shaped outlet channel, it is not easy to enter the water source inside it; a water intake pipe extends from one end inside the water tank to the bottom of the η-shaped outlet channel, and can pump out water at the bottom of the water tank; the water tank has a simple structure and does not require specific civil engineering reconstruction; the water tank can be in a long strip shape and arranged along the track; the water intake pipe slides forward in the water tank and is not limited by the water supply distance.

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1As shown, an embodiment of the present invention provides a water supply equipment for loading and unloading equipment, including a water tank and a water intake pipe 1. An η-shaped outlet channel 7 is provided on one side of the water tank, and the opening of the η-shaped outlet channel 7 faces downward. One end of the water intake pipe 1 is inserted into the η-shaped outlet channel 7 and extends to the bottom of the η-shaped outlet channel 7. The other end of the water intake pipe 1 is connected to the loading and unloading equipment. The η-shaped outlet channel 7 of the water tank opens downward, so that external bulk dust is not easy to float into the η-shaped outlet channel 7, and the η-shaped outlet channel 7 presents a tortuous maze-like structure. Even if a small amount of dust floats in from the opening of the η-shaped outlet channel 7, it is not easy to enter the water source inside it; the part of the water intake pipe 1 inside the water tank is consistent with the shape of the η-shaped outlet channel 7 of the water tank, and the water suction port of the water intake pipe 1 extends to the bottom of the η-shaped outlet channel 7, so that the water intake pipe 1 can draw away the water at the bottom of the η-shaped outlet channel 7 when pumping water; and the water tank has a simple structure and does not require specific civil engineering modifications. The water tank is long and strip-shaped and is arranged along the track. The water intake pipe slides forward in the water tank and is not limited by the water supply distance.

[0020] In some embodiments, a sealing brush 4 is provided between the opening of the η-shaped outlet channel 7 and the water intake pipe 1, so that when air enters the water tank, the sealing brush 4 can filter out bulk dust in the air, thereby improving the sealing performance of the water tank. The sealing brush 4 can be disassembled, thereby making it more convenient to clean or replace the sealing brush 4.

[0021] In some embodiments, a baffle is provided between the η-shaped outlet channel 7 and the water tank 8, thereby defining the η-shaped outlet channel 7 and the water tank 8. A through hole connecting the η-shaped outlet channel 7 and the bottom of the water tank 8 is provided, so that when the water intake pipe 1 draws water from the η-shaped outlet channel 7, the water in the water tank 8 can flow into the η-shaped outlet channel 7 through the through hole.

[0022] Furthermore, a heating pipe 5 is provided at the bottom of the water tank 8, so that when the water tank supplies water in cold weather, the water in the water tank is heated by the heating pipe 5, so that the water temperature in the water tank is maintained above 0 degrees Celsius, ensuring that the water in the water tank will not freeze, thereby not affecting the normal water supply.

[0023] Furthermore, a heat-insulating layer may be provided outside the water tank, thereby improving the heat-insulating performance of the water tank and further preventing the water in the water tank from freezing in a cold environment.

[0024] In some embodiments, an upper cover plate 2 is provided on the top of the water tank 8. The upper cover plate 2 can be opened to store water in the water tank 8. The upper cover plate 2 can cover the edge of the water tank, thereby improving the sealing performance of the water tank.

[0025] In some examples, the inner wall of the water tank 8 is provided with a high water level limit switch 61 and a low water level limit switch 62. The high water level limit switch 61 is used to sound an alarm when the water in the water tank 8 is too high. Since the n-shaped outlet channel 7 is connected to the water tank 8, the water levels of the two are consistent. If the water level is too high, some water may spill out of the n-shaped outlet channel 7 during the movement of the water tank. The low water level limit switch 62 is used to sound an alarm when the water level in the water tank 8 is too low, so as to remind the staff to add water to the water tank 8 in time.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
