Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.

As shown in fig. 1 to 3, which are schematic structural views of the floating dock provided by the present invention. The floating dock comprises a hull 10, at least one control cabin 20 arranged on the hull 10, and at least one balancing cabin 30 symmetrically distributed with the control cabin 20. It is contemplated that the floating dock may further include functional modules such as sea chests 40 mounted to the bottom of the hull 10 for communication with external water flow, ballast tanks, mounting assemblies, electrical connection assemblies, etc., which are well known to those skilled in the art and will not be described in detail herein.

Guard rails may be respectively installed on both sides of the top of the hull 10 and the top edges of the balance tank 30 and the control tank 20 to provide a protection function. The side surfaces of the balance tank 30 and the control tank 20 may be provided with a stair or the like, so that a crew can conveniently get on the control tank 20 and the top of the balance tank 30 for maintenance or operation. The sides of the control pod 20 are marked with a waterline to enable the user to confirm the draft.

The hull 10 comprises at least one pump chamber 12, at least one empty chamber 13, and a ballast tank 14 disposed between the pump chamber 12 and the empty chamber 13. The pump chamber 12 and the empty chamber 13 are respectively arranged at two ends of the inner part of the ballast tank 14, and the ballast tank 14 is arranged in the middle of the ship body 10 to balance buoyancy. It is of course conceivable that the hollow chamber 13 may be provided with a pipe pump assembly 121, and the pipe pump assembly 121 pumps water or discharges water, when necessary, to improve the efficiency of pumping water or discharging water.

In this embodiment, two sets of pump modules 121 are installed inside the pump chamber 12, and of course, the number of pump modules 121 can be changed according to actual needs to adapt to floating docks with different sizes, thereby improving the working efficiency. As shown in fig. 2, which is a plan view of the tube pump assembly 121. Each set of tube pump assemblies 121 includes a pump body assembly 122, and a tube set 15 communicating the pump body assembly 122, the ballast tank 14, and the exterior of the hull 10. It is understood that the pump body assembly 122 includes a water pump, and additional devices, etc., which are well known in the art and will not be described in detail herein. The piping 15 includes an inlet pipe 151 communicating the pump body assembly 122 with the outside, a first pipe 152 communicating the pump body assembly 122 with the ballast tank 14, a second pipe 153 communicating the inlet pipe 151 with the first pipe 152, and an outlet pipe 154 communicating the first pipe 152 with the outside of the hull 10. The water inlet pipe 151 and the water outlet pipe 154 are respectively used as a water inlet passage and a water outlet passage of the whole pump body assembly 122, and play a role in communicating with external water flow. When drained, the pump body assembly 122 draws water in the ballast tank 14 under suction of the pump body assembly 122 down the first conduit 152 and out of the tube pump assembly 121 and the ballast tank 14 through the outlet tube 154. When it is desired to fill the ballast tank 14 with water to make the floating dock submerged, the external water flow first enters the sea chest 40, then passes through the inlet pipe 151 and is introduced into the ballast tank 14 by the second pipe 153. It is contemplated that, in accordance with the principles of a communicating vessel, the pump body assembly 122 is not required to draw water from the outside, and that, by opening the sea chest 40, water naturally enters the sea chest 40 under the force of gravity and then enters the ballast tank 14 through the second conduit 153. It is contemplated that the sea chest 40, and the first pipe 152 are disposed at the bottom of the pump chamber 12 in order to allow external water, such as river or river water, to smoothly enter the ballast tank 14, thereby facilitating entry and drainage.

The water inlet pipe 151, the first pipe 152, the second pipe 153 and the water outlet pipe 154 are respectively provided with a butterfly valve 16. And in the process of filling water or pumping water, the butterfly valves 16 are respectively switched on and off, so that the corresponding pipelines are closed or opened, and the filling water or pumping water is realized. Specifically, when water is drained, the butterfly valves 16 on the water inlet pipe 151 and the second pipe 153 are closed, and the butterfly valves 16 on the first pipe 152 and the water outlet pipe 154 are opened. On the contrary, when water is supplied, the butterfly valve 16 of the inlet pipe 151 and the second pipe 153 is opened, and the butterfly valve 16 of the first pipe 152 and the outlet pipe 154 is closed. The butterfly valve 16 may be remote controlled and controlled by the control device of the control cabin 20, so as to adjust the on-off and flow rate of the pipeline. The inlet pipe 151 may also be provided with a filter 156 for filtering water to ensure that the water entering the pump-in-line assembly 121 is clean. The outlet of the outlet pipe 154 is provided with a stop check valve 17 for blocking the external water flow from entering the pump-in-pipe assembly 121 through the outlet pipe 154 when the hull 10 sinks with the waterline exceeding the height of the outlet. In addition, in order to avoid external water from entering the water outlet pipe 154, the water outlet of the water outlet pipe 154 is arranged outside the ballast tank 14, and preferably, the water outlet of the water outlet pipe 154 should be larger than the maximum draft of the floating dock relative to the height of the ballast tank 14.

A pressure balance pipeline 155 is communicated between the first pipelines 152 of the two pipe pump assemblies 121, and a valve is mounted on the pressure balance pipeline 155, so that the on-off of the two pipe pump assemblies 121 can be controlled, when the two pipe pump assemblies 121 are communicated with each other, the air pressure in all the communicated pipelines is balanced and equal, and further, the flow rate of each water inlet on the ballast tank 14 is relatively consistent.

The operation flow of the tube pump assembly 121 is as follows: when the floating dock is normally floating on the water, i.e., not in use, the butterfly valve 16 on the inlet pipe 151 and the outlet pipe 154 is closed. When the ship needs to be repaired, the butterfly valve 16 on the water inlet pipe 151 and the second pipe 153 is opened, the butterfly valve 16 on the water outlet pipe 154 and the first pipe 152 is closed, and the external water flow is automatically flowed into the ballast tank 14 under the pressure, so that the floating dock sinks. When the vessel is driven off the floating dock, the butterfly valve 16 on the outlet pipe 154 and the first pipe 152 is opened, the butterfly valve 16 on the inlet pipe 151 and the second pipe 153 is closed, the water pump assembly 122 is controlled to open to draw water from the ballast tank 14, the drawn water passes through the outlet pipe 154 and exits the hull 10 through the stop check valve 17.

In this embodiment, two sets of the pump modules 12 are symmetrically disposed in the pump chamber 12, so that the efficiency of water intake and drainage can be improved, and the whole floating dock can be left-right balanced when water is drained or intake. The pipe pump assembly 121 further comprises pressure balance pipes 155 communicating the two symmetrically distributed pipe pump assemblies 121, and the pressure balance pipes can automatically adjust the air pressure balance in the two second pipes 153 or the two first pipes 152 in the process of water filling and water draining, so that the water inlet speed of the two second pipes 153 or the water outlet speed of the two first pipes 152 are kept relatively consistent, the water inlet speed or the water outlet speed of symmetrical water inlets on the ballast tank 14 is kept relatively consistent, and the ship body 10 is ensured to float upwards or descend stably. It is noted that the butterfly valve 16 in the first conduit 152 is positioned close to the pump assembly 122, and when the butterfly valve 16 in the first conduit 152 is closed, water in the ballast tank 14 is only prevented from flowing out through the outlet pipe 154, and at this time, the pressure balance conduits 155 installed in the two first conduits 152 are still capable of communicating with the two second conduits 153.

In the present embodiment, the stop check valve 17 is a cast steel flange stop check valve, model A25050, CB/1585-. The second stop check valve 18 is a cast steel flange stop check valve, model number A160150, CB/1585-. The model number of the butterfly valve 16 is DN 150. The model of the filter screen 19 is A40, CB 623-80. These are all embodiments of the present invention, and the specific model can be adjusted according to actual needs.

Compared with the prior art, the pipe pump assemblies 121 of the floating dock are symmetrically distributed, so that when the pipe pump assemblies 121 are used for increasing weight during irrigation or decreasing weight during drainage, the weight of two sides of the ship body 10 can be increased or decreased simultaneously, and the balance of the ship body 10 is ensured. The first pipelines 152 of the two symmetrical pipe pump assemblies 121 are communicated with each other, so that the two pipe pump assemblies 121 can balance air pressure in each pipeline during water filling and water draining, the same water pumping and draining speed of the different pipe pump assemblies 121 is ensured, and the ship body 10 can keep stable in floating or submerging.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
