Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ships, and in particular to a horizontal ventilation device with a floating ball. Background Art
[0002] In many large double-bottom ships, due to the division of tanks, there will be some liquid tanks distributed near the middle of the ship, far from the side, and the top is an empty cargo hold area, so it is impossible to arrange vertical air pipes for ventilation. If horizontal steel pipes are arranged directly, due to the certain height of the structural frame, the horizontal steel pipes cannot be arranged on the top of the liquid tank, and the ventilation effect is poor. Under extreme working conditions, the horizontal steel pipes will be filled with water, and there will be a suffocation on the top of the liquid tank. Therefore, under normal circumstances, a section of horizontal structural wall will be used as an extension of the liquid tank, passing through the top of the side tank to the side, and then vertical air pipes will be installed for ventilation.
[0003] The structural walls need to be arranged as close to the bow and stern of the side tank as possible. Otherwise, the walls may divide the top of the side tank into multiple partitions, resulting in the need for special consideration of the ventilation of the side tank.
[0004] The solution of achieving horizontal ventilation through structural walls also has the following defects: the wall space is small, the construction is difficult, and it will increase the weight of steel and has poor economy. Summary of the invention
[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a horizontal ventilation device with a float.
[0006] The present invention solves the above technical problems through the following technical solutions:
[0007] A horizontal ventilation device with a floating ball comprises a ventilation pipe extending from a liquid tank of a ship to the outside of the liquid tank; the ventilation pipe comprises a transverse pipe; an extension pipe extending upward is provided at the end of the transverse pipe located in the liquid tank; a gap is provided between the top of the extension pipe and the tank top of the liquid tank; a discharge port is provided at the bottom of the transverse pipe, and the discharge port is located in the liquid tank; the discharge port is connected to a floating ball component which can block the discharge port when the liquid level of the liquid tank rises and open the discharge port when the liquid level of the liquid tank drops.
[0008] Furthermore, the float component includes a shell, a float arranged in the shell, and a mesh portion arranged at the bottom of the shell; the shell is connected to the discharge port; the shell includes a reducing portion, the inner diameter of the top of the reducing portion is smaller than the outer diameter of the float, and the inner diameter of the bottom of the reducing portion is larger than the outer diameter of the float.
[0009] Furthermore, the diameter-changing portion is in a truncated cone shape.
[0010] Furthermore, the shell also includes a lower shell, which is connected to the bottom of the diameter-changing portion; the inner diameter of the lower shell is greater than the outer diameter of the float.
[0011] Furthermore, the lower shell is tubular.
[0012] Furthermore, the mesh portion is fixed to the bottom of the lower shell.
[0013] Furthermore, the shell also includes an upper shell, the bottom of which is connected to the top of the diameter-reducing portion; and the top of which is fixed to the transverse tube.
[0014] Further, the discharge port is located in an area enclosed on the transverse tube by a connection between the upper shell and the transverse tube.
[0015] Furthermore, the upper shell is tubular.
[0016] Furthermore, the mesh portion is a wire mesh.
[0017] The beneficial effect of the present invention is that the present invention opens and closes the discharge port at the bottom of the vent pipe by floating up and down the float ball, which can discharge the residual liquid in the transverse pipe of the vent pipe when the liquid level gradually decreases, and can close the discharge port when the liquid level gradually increases to prevent the liquid from entering the transverse pipe of the vent pipe and affecting the ventilation effect. The present invention is easy to install, reduces the construction workload, and also significantly reduces the steel consumption, reduces the weight of the ship, and saves economic costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention.
[0019] Figure 2 It is a structural schematic diagram of a float component of a preferred embodiment of the present invention. DETAILED DESCRIPTION
[0020] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0021] like Figure 1 and Figure 2 As shown, a horizontal ventilation device with a floating ball comprises a ventilation pipe 20 extending from a liquid tank 10 of a ship to the outside of the liquid tank. The ventilation pipe 20 comprises a transverse pipe 21.
[0022] The end of the transverse pipe 21 located in the liquid tank is provided with an upwardly extending extension pipe 22. A gap is provided between the top of the extension pipe 22 and the tank top 12 of the liquid tank.
[0023] A discharge port 24 is formed at the bottom of the transverse tube 21 and is located inside the liquid tank 10 .
[0024] The drain port 24 is connected to a float member 30 that can block the drain port when the liquid level of the liquid tank rises and open the drain port when the liquid level of the liquid tank drops.
[0025] The float member 30 includes a housing 31 , a float 32 disposed in the housing, and a mesh portion 33 disposed at the bottom of the housing. The mesh portion is a steel mesh. The housing 31 is connected to the discharge port 24 .
[0026] The housing 31 includes a diameter reducing portion 34. The inner diameter of the top of the diameter reducing portion 34 is smaller than the outer diameter of the float 32, and the inner diameter of the bottom of the diameter reducing portion 34 is larger than the outer diameter of the float 32. The diameter reducing portion is truncated cone-shaped.
[0027] The housing 31 further includes a lower housing 35, which is connected to the bottom of the diameter-changing portion 34; the inner diameter of the lower housing 35 is greater than the outer diameter of the floating ball 32. The lower housing 35 is tubular.
[0028] The net portion 33 is fixed to the bottom of the lower housing 31 .
[0029] The housing 31 further includes an upper housing 36, the bottom of which is connected to the top of the reducing portion 34; the top of the upper housing 36 is fixed to the transverse tube 21, and the discharge port 24 is located in the area enclosed by the connection between the upper housing and the transverse tube on the transverse tube. The upper housing 36 is tubular.
[0030] When the liquid level in the liquid tank 10 drops, the float 32 drops accordingly until it falls on the mesh portion 33. The liquid remaining in the transverse tube 21 flows through the discharge port 24 and the inner cavity of the shell 31 of the float component under the action of gravity and then discharges from the mesh portion.
[0031] When the liquid level in the liquid tank 10 rises, the liquid in the liquid tank enters the shell 31 from the mesh portion 33, and the float 32 floats up until it hits the top of the reducing portion 34. The float 32 seals the discharge port 24 under the action of buoyancy, thereby preventing the liquid from entering the vent pipe and affecting the venting effect.
[0032] The compartment outside the tank can be a side tank, or an empty tank, or other compartments. The vent pipe also includes a vent pipe 23 arranged at the end of the transverse pipe outside the tank. The tank is connected to the atmosphere through the vent pipe.
[0033] The present invention uses a steel pipe to replace the structural enclosure wall in the prior art. The present invention opens and closes the discharge port at the bottom of the air-permeable pipe by floating up and down the float ball, which can discharge the residual liquid in the transverse pipe of the air-permeable pipe when the liquid level gradually decreases, and can close the discharge port when the liquid level gradually increases to prevent the liquid from entering the transverse pipe of the air-permeable pipe and affecting the ventilation effect.
[0034] The invention is easy to install, reduces the construction workload, significantly reduces the steel consumption, reduces the weight of the ship, and saves economic costs.
[0035] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
