Description

Technical Field

[0001] This utility model belongs to the field of ship hatch technology, specifically relating to a ship hatch sealing device. Background Technology

[0002] Ships are one of the main means of transportation today. Ship transport has advantages such as large transport capacity and low price. Cargo is stored in the ship's hold, and people can enter and exit the hold through the hatch. The hatch is equipped with a door to seal and protect the hold. The door must have a locking function to prevent people from accidentally entering, and the door has high sealing requirements.

[0003] Currently common hatch locking structures, such as those using a handwheel and locking rod, involve turning the handwheel so that the end of the locking rod extends and locks the hatch edge. This locking method requires manual turning of the handwheel, which is inconvenient as the hatch needs to be opened frequently during inspection and maintenance. Furthermore, this method suffers from insufficient locking force of the locking rod, which can lead to a decrease in sealing performance.

[0004] Therefore, a ship hatch sealing device is needed to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a ship hatch sealing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ship hatch sealing device, including a bulkhead, a hatch is provided on the side of the bulkhead, a hatch plate is fitted inside the hatch, an opening and closing assembly is provided on the outer side wall of the bulkhead to drive the hatch plate to open and close, a flange plate is fixed inside the hatch, a rubber frame strip is attached and fixed on the side of the flange plate, an inner cavity is provided inside the rubber frame strip, and a liquid replenishment assembly communicating with the inner cavity is provided on the back of the bulkhead.

[0007] It should be noted in the scheme that the opening and closing assembly includes a U-shaped liquid cylinder fixed to the outer wall of the bulkhead, a connecting rod fixed to the side of the door plate and inserted into one end of the U-shaped liquid cylinder, a piston plate c fixed to the end of the connecting rod and tightly fitted with the inner wall of the U-shaped liquid cylinder, a hydraulic push rod fixed to the outer wall of the bulkhead, the output rod of the hydraulic push rod inserted into the other end of the U-shaped liquid cylinder, a piston plate a fixed to the end of the output rod of the hydraulic push rod and tightly fitted with the inner wall of the U-shaped liquid cylinder, an internal ring plate fixed inside the U-shaped liquid cylinder, and a spring provided inside the U-shaped liquid cylinder, the two ends of the spring being fixed to the side of the internal ring plate and the side of the piston plate c, respectively.

[0008] It is worth noting that a support plate is fixed on the outer wall of the bulkhead, and the U-shaped liquid cylinder passes through the support plate and is fixed to the support plate.

[0009] Furthermore, it should be noted that the fluid replenishment assembly includes a liquid cylinder fixed to the outer wall of the rubber frame and communicating with the inner cavity. A nut sleeve is fixed inside the end of the liquid cylinder away from the rubber frame. A threaded rod inserted into the liquid cylinder is threadedly connected to the nut sleeve. A piston plate b that fits tightly against the inner wall of the liquid cylinder is fixed to the end of the threaded rod inside the liquid cylinder.

[0010] In a preferred embodiment, an end plate is fixed to one end of the threaded rod located outside the liquid cylinder, and a rubber sleeve is fitted onto the surface of the end plate.

[0011] In a preferred embodiment, a protrusion is fixed on the side of the connecting rod and arranged along the length of the connecting rod, and a guide groove is provided at the port of the U-shaped liquid cylinder to slide and adapt to the protrusion.

[0012] Compared with the prior art, the ship hatch sealing device provided by this utility model has at least the following beneficial effects:

[0013] (1) The hatch panel is hydraulically pushed by the opening and closing assembly, so that the hatch panel moves into the hatch and presses the rubber frame strip inside the hatch. The inner cavity of the rubber frame strip is filled with liquid. The hatch panel presses the rubber frame strip to generate elastic expansion, so that the elastic expansion of the rubber frame strip fully seals the gap between the hatch panel and the hatch, thereby sealing and closing the hatch panel, effectively improving the sealing performance when the hatch panel is closed. When it is necessary to open the hatch, the hydraulic pressure on the hatch panel is removed by the opening and closing assembly, so that the hatch panel can be automatically moved out of the hatch, thereby opening the hatch and facilitating the entry and exit of personnel. The hatch panel locking operation is convenient and there is no problem of loose locking, avoiding the problem of forgetting to close or not closing the hatch panel properly.

[0014] (2) When the rubber frame strip undergoes a certain amount of plastic deformation after long-term use, which reduces the sealing effect of the rubber frame strip on the hatch panel, the liquid replenishment component is used to replenish the liquid in the inner cavity to replenish the expansion of the rubber frame strip, thereby replenishing the sealing effect of the rubber frame strip on the hatch panel and ensuring that the hatch panel is always well sealed when closed.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-5 This utility model provides a ship hatch sealing device, including a bulkhead 4, a hatch 5 on the side of the bulkhead 4, a hatch 3 fitted inside the hatch 5, an opening and closing assembly 1 on the outer side of the bulkhead 4 for opening and closing the hatch 3, a flange plate 8 fixed inside the hatch 5, a rubber frame strip 6 attached to the side of the flange plate 8, an inner cavity 7 inside the rubber frame strip 6, and a liquid replenishment assembly 2 communicating with the inner cavity 7 on the back of the bulkhead 4; the opening and closing assembly 1 hydraulically pushes the hatch 3, causing the hatch 3 to move into the hatch 5, and the hatch 3 presses tightly against the rubber frame strip 6 inside the hatch 5. The inner cavity 7 of the rubber frame strip 6 is filled with liquid, so that the hatch 3 presses against the rubber frame strip 6 to generate elastic expansion, thereby sealing the hatch 3 and the hatch 5 through the elastically expanded rubber frame strip 6. The gaps in hatch 5 are fully sealed to seal hatch panel 3, effectively improving its sealing performance when closed. When hatch 5 needs to be opened, the hydraulic pressure on hatch panel 3 is removed by the opening and closing assembly 1, allowing hatch panel 3 to automatically move out of hatch 5 and open hatch 5. The locking operation of hatch panel 3 is convenient and there is no problem of loosening, avoiding the problem of forgetting to close or not closing hatch panel 3 properly. When the rubber frame strip 6 undergoes a certain amount of plastic deformation after prolonged use, causing a decrease in the sealing effect of the rubber frame strip 6 on hatch panel 3, the liquid replenishment assembly 2 replenishes the liquid in the inner cavity 7 to compensate for the expansion of the rubber frame strip 6, thereby replenishing the sealing effect of the rubber frame strip 6 on hatch panel 3 and ensuring that hatch panel 3 is always well sealed when closed.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the opening and closing assembly 1 includes a U-shaped liquid cylinder 104 fixed to the outer wall of the bulkhead 4. A connecting rod 106 is fixed to the side of the door plate 3 and inserted into one end of the U-shaped liquid cylinder 104. A piston plate c105 that fits tightly against the inner wall of the U-shaped liquid cylinder 104 is fixed to the end of the connecting rod 106. A hydraulic push rod 101 is fixed to the outer wall of the bulkhead 4. The output rod of the hydraulic push rod 101 is inserted into the other end of the U-shaped liquid cylinder 104. A piston plate c105 that fits tightly against the inner wall of the U-shaped liquid cylinder 104 is fixed to the end of the output rod of the hydraulic push rod 101. The piston plate a103 is assembled, and an internal ring plate 110 is fixed inside the U-shaped liquid cylinder 104. A spring 109 is installed inside the U-shaped liquid cylinder 104, and the two ends of the spring 109 are fixed to the side of the internal ring plate 110 and the side of the piston plate c105, respectively. The U-shaped liquid cylinder 104 is filled with liquid, which can be water or hydraulic oil, etc. When the hydraulic push rod 101 is activated, the output rod of the hydraulic push rod 101 extends and drives the piston plate a103 to move inside the U-shaped liquid cylinder 104. The piston plate a103 presses the liquid inside the U-shaped liquid cylinder 104. Through Pascal's principle, the hydraulically driven piston plate c105 moves within the U-shaped liquid cylinder 104. At this time, the spring 109 is in a stretched state. The piston plate c105 pushes the hatch door plate 3 via the connecting rod 106, causing the hatch door plate 3 to move into the hatch opening 5. The hatch door plate 3 then presses tightly against the rubber frame strip 6 inside the hatch opening 5. This pressure causes the rubber frame strip 6 to expand elastically, effectively sealing the gap between the hatch door plate 3 and the hatch opening 5. To improve the sealing performance of hatch panel 3 when closed, when hatch 5 needs to be opened, the hydraulic push rod 101 drives the piston plate a103 to move in the opposite direction, thereby removing the hydraulic pressure on the piston plate c105, i.e., removing the pressure on hatch panel 3. At this time, the spring 109 retracts to its original length, thereby pulling the piston plate c105 back to its original position, i.e., pulling the hatch panel 3 to automatically move out of hatch 5, thus opening hatch 5. The locking operation of hatch panel 3 is convenient and there is no problem of loose locking, avoiding the problem of forgetting to close or not closing hatch panel 3 properly.

[0024] Further as Figure 1 and Figure 3 As shown, it is worth noting that a support plate 107 is fixed on the outer wall of the bulkhead 4, and a U-shaped liquid cylinder 104 passes through the support plate 107 and is fixed to the support plate 107. In actual operation, the U-shaped liquid cylinder 104 is fixed by the support plate 107 to improve the working stability of the U-shaped liquid cylinder 104.

[0025] Further as Figure 3 and Figure 5As shown, it is worth noting that the fluid replenishment assembly 2 includes a liquid cylinder 201 fixed to the outer wall of the rubber frame 6 and communicating with the inner cavity 7. A nut sleeve 204 is fixed inside the end of the liquid cylinder 201 away from the rubber frame 6. A threaded rod 203 inserted into the liquid cylinder 201 is threadedly connected to the nut sleeve 204. A piston plate b202, which fits tightly against the inner wall of the liquid cylinder 201, is fixed to the end of the threaded rod 203 located inside the liquid cylinder 201. After prolonged use, the rubber frame 6 undergoes a certain degree of plastic deformation, causing the rubber... When the sealing effect of the frame strip 6 on the hatch panel 3 decreases, there is a certain amount of liquid in the liquid cylinder 201. The liquid can be water or hydraulic oil, etc. By rotating the threaded rod 203, the threaded rod 203 drives the piston plate b202 to move in the liquid cylinder 201, thereby pressing the liquid in the liquid cylinder 201 into the inner cavity 7 through the piston plate b202, replenishing the liquid in the inner cavity 7, replenishing the expansion of the rubber frame strip 6, thereby replenishing the sealing effect of the rubber frame strip 6 on the hatch panel 3, and ensuring that the hatch panel 3 is always well sealed when closed.

[0026] This solution involves the following working process: The hydraulic push rod 101 is activated, extending its output rod and driving the piston plate a103 to move within the U-shaped liquid cylinder 104. The piston plate a103 presses the liquid within the U-shaped liquid cylinder 104, thereby, through Pascal's principle, hydraulically pressing the piston plate c105 to move within the U-shaped liquid cylinder 104. At this time, the spring 109 is in a stretched state, and the piston plate c105 pushes the hatch panel 3 via the connecting rod 106, causing the hatch panel 3 to move into the hatch opening 5. The hatch panel 3 then presses tightly against the rubber frame strip 6 inside the hatch opening 5, causing the rubber frame strip 6 to expand elastically. This elastically expanded rubber frame strip 6 effectively seals the gap between the hatch panel 3 and the hatch opening 5, thus securing the hatch panel 3. The sealing mechanism effectively improves the sealing performance of the hatch panel 3 when it is closed. When it is necessary to open the hatch 5, the hydraulic push rod 101 drives the piston plate a103 to move in the opposite direction, thereby removing the hydraulic pressure on the piston plate c105, i.e., removing the pressure on the hatch panel 3. At this time, the spring 109 retracts to its original length, thereby pulling the piston plate c105 back to its original position, i.e., pulling the hatch panel 3 to move automatically out of the hatch 5, thus opening the hatch 5. By rotating the threaded rod 203, the threaded rod 203 drives the piston plate b202 to move in the liquid cylinder 201, thereby pressing the liquid in the liquid cylinder 201 into the inner cavity 7 through the piston plate b202, replenishing the liquid in the inner cavity 7, replenishing the expansion of the rubber frame strip 6, and thus improving the sealing effect of the rubber frame strip 6 on the hatch panel 3.

[0027] Further as Figure 5As shown, it is worth noting that an end plate 205 is fixed on one end of the threaded rod 203 located outside the liquid cylinder 201, and a rubber sleeve is fitted on the surface of the end plate 205; in actual operation, the threaded rod 203 can be easily rotated through the end plate 205, which facilitates operation.

[0028] Further as Figure 1 As shown, it is worth noting that a protrusion 108 is fixed on the side of the connecting rod 106 and arranged along the length of the connecting rod 106. A guide groove is provided at the end of the U-shaped liquid cylinder 104 to slide and adapt to the protrusion 108. In actual operation, the protrusion 108 and the guide groove cooperate to guide and limit the sliding of the connecting rod 106, so as to avoid the deflection of the hatch panel 3.

[0029] In summary: The opening and closing assembly 1 hydraulically pushes the hatch panel 3, causing it to move into the hatch 5. The hatch panel 3 presses tightly against the rubber frame strip 6 inside the hatch 5. The inner cavity 7 of the rubber frame strip 6 is filled with liquid. The pressure from the hatch panel 3 on the rubber frame strip 6 causes elastic expansion, which effectively seals the gap between the hatch panel 3 and the hatch 5, thus sealing the hatch panel 3 and improving its sealing performance when closed. When it is necessary to open the hatch 5, the hydraulic pressure on the hatch panel 3 is released via the opening and closing assembly 1, allowing the hatch to open from the hatch 5. The hatch panel 3 can be automatically moved out from the hatch 5, thereby opening the hatch 5. The locking operation of the hatch panel 3 is convenient and there is no problem of loose locking, avoiding the problem of forgetting to close or not closing the hatch panel 3 properly. When the rubber frame strip 6 undergoes a certain plastic deformation after long-term use, causing the sealing effect of the rubber frame strip 6 on the hatch panel 3 to decrease, the liquid replenishment component 2 replenishes the liquid in the inner cavity 7 to compensate for the expansion of the rubber frame strip 6, thereby replenishing the sealing effect of the rubber frame strip 6 on the hatch panel 3, ensuring that the hatch panel 3 is always well sealed when closed.

[0030] The hydraulic push rod 101 can be purchased from the market. The hydraulic push rod 101 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
