With the advancement of technology, human resources can be extended from land to rivers, oceans and even the seabed. Many areas of science and technology related to rivers and oceans are flourishing. For example, mining in the sea, reclamation, beach maintenance, environmental protection, and submarine trenches , sea airport and even archaeological areas. The biggest difference between the development of rivers or marine resources and land resources is the need for dredging, and the dredging equipment industry has developed rapidly.

At present, the dredging equipment commonly used has various dredgers. Among them, the backhoe dredger has a large backhoe excavator installed on the deck of the ship, and the robot arm can rotate and penetrate into the water around the ship, and then The bucket at the front of the robot arm digging the sediment or sediment in the water. Due to the need to work in the water, the backhoes and buckets of backhoe excavators are much larger than the land excavators. In order to drive such large equipment, large engines are required, so the engine is required. The cooling system must be more efficient. In addition, the backhoe dredger usually works on the sea surface or the river surface some distance from the land, so the heat dissipation requirement for the engine is higher. Otherwise, if the engine fails on the sea surface or the river surface, it is not easy to repair. It is more likely to cause accidents such as equipment damage and even hull damage.

At present, the engine cooling system used by the general backhoe dredger is air-cooled, but in the face of the increasingly complex and increasingly large backhoes, the air-cooled cooling system does not meet the cooling efficiency. demand. The water-cooled cooling system is more efficient than the air-cooled type. However, due to the limited hull space and the backhoe excavator rotating on the hull, the water-cooled cooling system is more difficult to implement on the backhoe dredger.

Therefore, it is necessary to develop a water-cooled cooling system that can be rotated with a backhoe excavator to solve the above problems.

In view of the above, it is an object of the present invention to provide a rotatable cooling water channel device that can cooperate with the rotation of an external device and provide water-cooled cooling of the external device.

In order to achieve the above object, the present invention provides a rotatable waterway cooling device comprising a waterway body, a receiving body, a first water inlet pipe and a first water outlet pipe, wherein the waterway body can be accommodated in the housing body and rotated therein. The waterway body includes a shaft center, a first water channel, and a second water channel. The first water channel and the second water channel extend from the surface of the water channel body toward the axis and surround the axis, and the two are not connected to each other. The receiving body has a water outlet corresponding to the first waterway and a water inlet corresponding to the second waterway. The first inlet pipe passes through the waterway body and can communicate with the first waterway and the external device, and the first outlet pipe passes through the waterway body and can communicate with the second waterway and the external device. The external device can drive the waterway body, the first inlet pipe and the first outlet pipe to rotate together.

Another object of the present invention is to provide a rotatable cooling water system that can cooperate with the rotation of an external device and provide water-cooled cooling of the external device.

In order to achieve the above object, the present invention provides a rotary cooling system comprising a waterway body, a receiving body, a first inlet pipe, a first outlet pipe, a second inlet pipe, a second outlet pipe, and a heat exchanger, wherein the water channel The body can be accommodated in the housing and rotated therein. The waterway body includes a shaft center, a first water channel, and a second water channel. The first water channel and the second water channel extend from the surface of the water channel body toward the axis and surround the axis, and the two are not connected to each other. The receiving body has a water outlet corresponding to the first waterway and a water inlet corresponding to the second waterway.

In order that the present invention may be more clearly described, the preferred embodiments are described in detail with reference to the drawings. 1A to FIG. 3, FIG. 1A is a schematic view of a rotatable cooling water channel device 1 according to an embodiment of the present invention, and FIG. 1B is a schematic view of the rotatable cooling water channel device 1 of FIG. 1A in another state. 2 is a partial schematic view of the rotatable cooling water channel device 1 of FIG. 1, and FIG. 3 is a partial schematic view of the rotatable cooling water channel device 1 of FIG. As shown in FIG. 1A to FIG. 3, the rotatable cooling water channel device 1 includes a water channel body 10, a receiving body 11, a first water inlet pipe 12, and a first water outlet pipe 13, wherein the water channel body 10 can be accommodated in the receiving body. In the middle, the first inlet pipe 12 and the first outlet pipe 13 are connected to the waterway body 10. The waterway body 10 has an axis 100 that can be rotated in the housing 11 such that the waterway body 10 is rotated to different angles as in Figures 1A and 1B. In addition, the water channel body 10 forms a first water channel 101 and a second water channel 102 that are not connected to each other, and both extend inwardly from the surface of the water channel body 10 and surround the axis 100, in other words, the first water channel 101 and the second water channel. 102 is an annular space surrounding the axis.

Referring to FIG. 1A and FIG. 1B, the receiving body 11 has two openings, that is, a water outlet 111 and a water inlet 112. The position of the water outlet 111 corresponds to the first water channel 101, and the position of the water inlet 112 corresponds to In the second water channel 102. When the water channel body 10 is placed in the housing 11, the water outlet 111 faces the first water channel 101 and the water inlet 112 faces the second water channel 102. In practice, the water outlet 111 and the water inlet 112 can be respectively connected to the water pipe so that the first water channel 101 and the second water channel 102 can communicate with the heat exchanger or the outside through the water pipe. Since the first water channel 101 and the second water channel 102 extend from the surface of the water channel body 10 toward the axis 100 and surround the axis 100, even if the water channel body 10 rotates, the water outlet 111 and the water inlet 112 are respectively facing the first water channel 101 and The second water channel 102 and the first water channel 101 and the second water channel 102 can still communicate with the heat exchanger or the outside through the water outlet 111 and the water inlet 112. Please note that the water outlet 111 and the water inlet 112 are located at different heights of the axis 100 in the specific embodiment except for being at different heights of the axis 100, but the practice is not limited thereto, for example, The nozzle and the water inlet can also be set at different heights but in the same radial direction, and the positions of the two must only correspond to the first water channel and the second water channel.

The first inlet pipe 12 can pass through the waterway body 10 and communicate with the first water channel 101. Further, in practice, the first inlet pipe 12 can also simultaneously communicate with an external device, thereby introducing water from the external device into the first water channel 101. Further, the first outlet pipe 13 can also pass through the waterway body 10 and communicate with the second water channel 102 and the external device, thereby introducing water in the second water channel 102 to the external device. Since the first inlet pipe 12 and the first outlet pipe 13 are both connected to the waterway body 10, the three can be rotated together along the axis 100, and regardless of the angle to which the waterway body 10 is rotated, the first channel 101 and the second channel 102 The water outlet 111 and the water inlet 112 of the housing 11 can be separately connected.

Please note that since the position of the second water channel 102 is lower than the first water channel 101, the first water outlet pipe 13 is bound to pass through the position of the first water channel 101 in order to connect the second water channel 102, so the first water outlet pipe 13 needs to be the first The water passages 101 are isolated from each other to prevent the water of the first water channel 101 and the second water channel 102 from mixing with each other. In the specific embodiment, the first water outlet pipe 13 and the first water channel 101 are separated from each other by the shape design of the first water channel 101 and the second water channel 102. Referring to FIG. 2 and FIG. 3 again, as shown in FIG. 2 and FIG. 3, the width of the annular space of the first water channel 101 and the second water channel 102 is not uniform.

Of course, in the practice, the first water channel and the first water outlet pipe can be isolated by different designs. For example, the first water channel and the second water channel of the water channel body have a uniform width, and the first water outlet pipe can be close to the first water channel. It is completely bypassed in the waterway body and does not pass through the first waterway.

In FIGS. 1A through 3, the waterway body 10 further includes a hole 103 located at a position of the axis 100 and penetrating the waterway body 10. The hole 103 can be used to accommodate the cable, so that the external device can be connected to the device or power source at the other end through the cable, thereby further improving the cooperation between the rotatable cooling water channel device 1 and the external device.

Since the rotatable cooling water channel device 1 is used as an external device and a cooling water circulation channel between the heat exchangers in practice, the cooling water systems in the first water channel 101 and the second water channel 102 are in different states, in detail One of them is cooling water with waste heat, and the other is cooling water without waste heat. 4A and 4B, FIG. 4A and FIG. 4B are schematic cross-sectional views of the rotatable cooling water channel device 1 of FIG. 1A and FIG. 1B along the A-A cut line and the B-B cut line, respectively.
