Description

Technical Field

[0001] The present invention relates to an electric hatch cover, in particular to an intelligent monitoring type electric hatch cover for bulk carriers applied in the ship field. Background Art

[0002] The main forms of ship hatch covers include lift-off type, folding type and side-shift type. The side-shift type hatch cover realizes its functions through a roller lifting mechanism, a hatch cover moving mechanism and a locking mechanism: the roller lifting mechanism uses a multi-row roller group to cooperate with a guide rail to complete the vertical lifting action of the hatch cover; the hatch cover moving mechanism is driven by a hydraulic or electric drive device and realizes lateral translation through a gear-rack or sprocket-chain drive; the locking mechanism uses a hydraulic bolt or an electromagnetic braking device to ensure an airtight / watertight seal between the hatch cover and the hatch opening. The existing side-shift type hatch cover requires multiple people to cooperate in the operation, and manual inspection of the sealing state at the splicing of the hatch cover is also required after the operation.

[0003] The patent with the publication number CN106379490A discloses a new type of electric control bulk carrier hatch cover mechanism, including a hatch opening and a hatch cover. The hatch cover includes a left hatch cover and a right hatch cover that are split. It is characterized in that: a double-output shaft drive unit is symmetrically installed on the inner wall of the hatch opening, and drive gears are fixedly installed at the ends of the two output shafts on both sides of the double-output shaft drive unit. On the front and rear parts of the lower surfaces of the left hatch cover and the right hatch cover, racks are fixedly installed, and the gears mesh with the racks on the front and rear parts of the left hatch cover and the right hatch cover. The structure of the present invention is scientifically and reasonably designed, and has the advantages of being easy to operate, energy-saving and environment-friendly, safe and reliable. It is a new type of electric control bulk carrier hatch cover mechanism with high innovation.

[0004] The above patent simplifies the opening and closing operation of the hatch cover through an electric drive method, but does not solve the problems of how to accurately detect the splicing and sealing state of the hatch cover after closing, and how to monitor the sealing state of the hatch cover in real time during use. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing ship hatch cover cannot monitor the sealing state after splicing in real time and the opening and closing operation is cumbersome.

[0006] To solve the above problems, the present invention provides an intelligent monitoring type electric hatch cover for a bulk carrier, which includes a left cover and a right cover that are slidably connected to the hatch enclosure.

When the left cover and the right cover complete the closing and splicing, the hydraulic cylinder drives the wedge block to move upward and abut against the wedge strip, thereby realizing the locking of the left cover and the right cover;

[0007] On the end face of the right cover on the splicing side, a plurality of infrared distance sensors arranged opposite to the left cover are fixedly connected. A detection hole for the detection light to pass through is opened on the splicing sealing strip. The detection light emitted by the infrared distance sensors passes through the detection hole and then reaches the splicing end face of the left cover and is reflected; the plurality of infrared distance sensors and the opening and closing mechanism are both connected to a control terminal. The control terminal is equipped with an opening and closing monitoring system. The opening and closing monitoring system includes a gap monitoring module. The input end of the gap monitoring module is respectively connected to the plurality of infrared distance sensors. The output end of the gap monitoring module is connected to a control module. The output end of the control module is respectively connected to a data analysis module, an opening and closing execution module, and an alarm module.

Guide blocks are fixedly connected to the lower end surfaces of the left cover and the right cover close to the spliced sealing strip.

[0012] As a further improvement of the present application, a circumferential sealing ring is fixedly sleeved on the outer wall of the upper part of the hatch enclosure. When the cover is closed, the inner walls of both the left cover and the right cover abut against the circumferential sealing ring.

[0013] As a further improvement of the present application, the circumferential sealing ring is provided with an annular cavity, and hydraulic oil is filled in the annular cavity; Parallel grooves for accommodating the circumferential sealing ring are provided on the front and rear walls of the hatch enclosure, and longitudinal grooves are provided on the left and right walls of the hatch enclosure.

[0031] The following describes two embodiments of this application in detail with reference to the accompanying drawings.

[0032] The first embodiment:

[0033] Figures 1-10An intelligent monitoring type bulk carrier electric hatch cover is shown, which includes a left cover 1 and a right cover 2 that are slidably connected to the hatch enclosure 4. At the splicing joint on the opposite sides of the left cover 1 and the right cover 2, a splicing sealing strip 3 fixedly connected to the left cover 1 is provided; the left cover 1 and the right cover 2 are connected with an opening and closing mechanism for driving the two to perform opening and closing actions. The opening and closing mechanism includes two pairs of rack plates 5 respectively fixedly connected to the outer sides of the left cover 1 and the right cover 2. A driving gear 6 is engaged inside the rack plate 5. The driving gear 6 is fixedly connected with a rotating cylinder 7 rotatably connected to the deck. The rotating cylinder 7 is connected to one end output shaft of a double-shaft motor 9 through a transmission gear set 8;

[0034] Specifically, please refer to Figure 3 and Figure 4 , the output shaft of the double-shaft motor 9 drives the rotating cylinder 7 to rotate through the transmission gear set 8. The rotating cylinder 7 drives the driving gear 6 to rotate. The driving gear 6 drives the rack plates 5 fixed on the outer sides of the left cover 1 and the right cover 2 to move horizontally. A pair of rack plates 5 respectively arranged on the left cover 1 and the right cover 2 drive the left cover 1 and the right cover 2 to move towards each other and away from each other, realizing the opening and closing actions of the left cover 1 and the right cover 2;

[0035] A hydraulic cylinder 12 with the bottom fixedly connected to the deck is provided inside the rotating cylinder 7. The movable end of the hydraulic cylinder 12 is fixedly connected with a wedge block 13. Wedge strips 14 cooperating with the wedge block 13 are fixedly connected to the lower end surfaces of the left cover 1 and the right cover 2. When the left cover 1 and the right cover 2 complete the closing and splicing, the hydraulic cylinder 12 drives the wedge block 13 to move upward and abut against the wedge strip 14, thereby realizing the locking of the left cover 1 and the right cover 2;

[0036] On the end surface of the right cover 2 on the splicing side, a plurality of infrared distance sensors 15 opposite to the left cover 1 are fixedly connected. A detection hole 301 for the detection light to pass through is opened on the splicing sealing strip 3. The detection light emitted by the infrared distance sensors 15 passes through the detection hole 301 and then reaches the splicing end surface of the left cover 1 and is reflected; the plurality of infrared distance sensors 15 and the opening and closing mechanism are both connected to the control terminal. The control terminal is equipped with an opening and closing monitoring system. The opening and closing monitoring system includes a gap monitoring module. The input end of the gap monitoring module is respectively connected to the plurality of infrared distance sensors 15. The output end of the gap monitoring module is connected with a control module. The output end of the control module is respectively connected with a data analysis module, an opening and closing execution module, and an alarm module. The output end of the opening and closing execution module is connected to the opening and closing mechanism.

[0037] Specifically, when performing the closing operation, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 9, the control terminal activates the opening and closing mechanism, and the left cover 1 and the right cover 2 move towards each other. The infrared distance sensor 15 monitors the distance between the left cover 1 and the right cover 2 in real time to obtain the real-time gap value. The data analysis module compares the real-time gap value with the set closing cover gap threshold. When the real-time gap value is not greater than the closing cover gap threshold, the opening and closing mechanism is closed. Similarly, during the opening cover operation, the opening and closing mechanism drives the left cover 1 and the right cover 2 to move away from each other in the opposite direction. The data processing module compares the real-time gap value with the set opening cover gap threshold. When the real-time gap value is not less than the opening cover gap threshold, the opening and closing mechanism is closed.

[0038] Compared with the existing hatch cover device, in the present invention, the infrared distance sensor 15 provided on the splicing end faces of the left cover 1 and the right cover 2 monitors the opening and closing gap of the hatch cover in real time, and cooperates with the opening and closing mechanism to realize the automatic opening and closing of the hatch cover, replacing the traditional multi-person cooperation operation mode and the method of manually detecting the sealing state, improving the operation efficiency and the accuracy of detecting the sealing performance; in addition, through the opening and closing monitoring system including an alarm module, when it is found that the local gap is too large after closing the cover, an alarm is sent in time, which is convenient for the operator to repair and dispose in time, realizing intelligent monitoring.

[0039] Please refer to Figures 1-3 , both the left cover 1 and the right cover 2 are in the shape of a cover body, and the two are spliced and enclosed to form a box structure with an open lower end; the rack plates 5 are fixedly connected to the front and rear side walls of the left cover 1 and the right cover 2 and are perpendicular to the splicing sealing strip 3. The lower end surfaces of the left cover 1 and the right cover 2 close to the splicing sealing strip 3 are fixedly connected with guide blocks 11. Guide grooves 401 for the guide blocks 11 to slide are opened on the front and rear side walls of the hatch enclosure 4. A guide rod 402 is fixedly connected in the guide groove 401. The guide rod 402 passes through the guide block 11 and is slidably connected thereto; both the left cover 1 and the right cover 2 are fixedly connected with sliding support legs 10 on the side away from the splicing sealing strip 3, and rollers that are in sliding contact with the deck are provided at the lower part of the sliding support legs 10.

[0040] Specifically, by providing the guide blocks 11 and the guide rods 402, the left cover 1 and the right cover 2 have better stability during the opening and closing operation. By providing the sliding support legs 10, the weight of the left cover 1 and the right cover 2 is carried, and at the same time, after closing the cover, the volume occupied on the deck surface is smaller, replacing the traditional fixedly arranged guide rails.

[0041] In this embodiment, a plurality of equally spaced infrared distance sensors 15 are fixedly connected to the inner wall of one side of the right cover 2 at the splicing end face.

[0042] Specifically, by providing a plurality of infrared distance sensors 15, the gap values at each splicing position of the left cover 1 and the right cover 2 are monitored in real time, and multiple positions of the splicing seam are monitored in real time. The data analysis module synchronously analyzes the real-time gap values obtained by the plurality of infrared distance sensors 15. When the difference between the real-time gap value obtained by at least one infrared distance sensor 15 and the real-time gap values obtained by most other infrared distance sensors 15 is greater than the set difference threshold, the real-time gap threshold of most infrared distance sensors 15 is used as the standard value, and the opening and closing mechanism operates based on the standard value for lid closing and opening operations. At the same time, the alarm module issues an alarm instruction to remind the operator to perform maintenance;

[0043] It should be specifically noted that the reasons for the incorrect real-time gap values obtained by a small number of infrared distance sensors 15 may be: First, a small number of infrared distance sensors 15 are damaged; Second, the parts of the left cover 1 and the right cover 2 near the infrared distance sensor 15 are deformed; Third, the self-poses of the left cover 1 and the right cover 2 are skewed.

[0044] Please refer to Figure 6 , a plurality of pressure sensors 16 are fixedly connected to the inner wall of the right cover 2 on the side of the splicing surface, and the detection ends of the pressure sensors 16 are in contact with the splicing sealing strip 3.

[0045] Specifically, the splicing pressure at the splicing position of the left cover 1 and the right cover 2 is monitored in real time by the pressure sensors 16, further improving the monitoring effect of the splicing quality. At the same time, the data analysis module compares the real-time splicing pressure value obtained by the pressure sensors 16 with the set splicing pressure threshold. When the real-time splicing pressure value is less than the set splicing pressure threshold, the opening and closing execution module starts the hydraulic cylinder 12, and the hydraulic cylinder 12 pushes the wedge block 13 to move upward to squeeze the wedge strip 14, thereby increasing the splicing pressure between the left cover 1 and the right cover 2 and improving the sealing effect of the splicing sealing strip 3 on the splicing seam.

[0046] Please refer to Figure 9 and Figure 10 , a circumferential sealing ring 17 is fixedly sleeved on the outer wall of the upper part of the hatch enclosure 4. When the lid is closed, the inner walls of both the left cover 1 and the right cover 2 are in contact with the circumferential sealing ring 17.

[0047] Specifically, by providing the circumferential sealing ring 17, water vapor is prevented from entering the cargo hold through the gap between the left cover 1 and the right cover 2 and the hatch enclosure 4.

[0048] Please refer to Figure 10, the circumferential sealing ring 17 is provided with an annular cavity 1701, and the annular cavity 1701 is filled with hydraulic oil; parallel grooves 403 for accommodating the circumferential sealing ring 17 are provided on the front and rear walls of the hatch enclosure 4, and longitudinal grooves 404 are provided on the left and right walls of the hatch enclosure 4. The vertical height of the inner bottom surface of the longitudinal groove 404 is lower than the vertical height of the lower end surfaces of both the left cover 1 and the right cover 2.

[0049] Specifically, during the process of closing the cover, the inner walls of the left cover 1 and the right cover 2 first come into contact with the part of the circumferential sealing ring 17 located at the parallel groove 403, and finally come into contact with the part of the circumferential sealing ring 17 located at the longitudinal groove 404. When the inner walls of the left cover 1 and the right cover 2 squeeze the part of the circumferential sealing ring 17 located at the longitudinal groove 404, the hydraulic oil in the circumferential sealing ring 17 flows from the part of the circumferential sealing ring 17 located at the longitudinal groove 404 into the part of the circumferential sealing ring 17 located at the parallel groove 403, so that the part of the circumferential sealing ring 17 located at the parallel groove 403 is in full contact with the inner walls of both the left cover 1 and the right cover 2, thereby improving the sealing effect. At the same time, a greater contact pressure is generated at the contact position between the splicing sealing strip 3 and the circumferential sealing ring 17, and the two cooperate to achieve a better sealing effect.

[0050] The second implementation method:

[0051] Figure 6 , Figure 8 , Figure 11 and Figure 12 An intelligent monitoring type bulk carrier electric hatch cover is shown. On the basis of the first implementation method, it further includes a leakage detection mechanism. The leakage detection mechanism includes a detection tube 18 penetrating through the inside of the splicing sealing strip 3. The detection tube 18 is provided with a suction hole 1801. The splicing sealing strip 3 is provided with a penetration hole 302 communicating with the suction hole 1801. The outer end opening of the penetration hole 302 abuts against the splicing end surface of the right cover 2;

[0052] One end of the detection tube 18 is connected to a blower 19. The air inlet end of the blower 19 is fixedly connected to a drying and filtering cylinder 20. The other end of the detection tube 18 is fixedly connected to a detection cylinder 21. A humidity sensor 22 is fixedly connected inside the detection cylinder 21. The detection cylinder 21 is communicated with the external atmosphere through an exhaust pipe 23.

[0053] Specifically, when performing leak detection, the blower 19 is started. The blower 19 injects the dry and clean gas that has been dried and filtered by the drying filter cartridge 20 into the detection tube 18. The airflow flowing through the detection tube 18 is finally injected into the detection cylinder 21. The humidity sensor 222 in the detection cylinder 21 detects the airflow flowing into the detection tube 18. When the humidity sensor 22 detects moisture, it indicates that there is a leak at the splicing position of the left cover 1 and the right cover 2. The moisture flows along the splicing end face of the right cover 2 into the penetration hole 302 and enters the detection tube 18 through the suction hole 1801, indicating that the moisture has entered the inner sides of both the left cover 1 and the right cover 2.

[0054] It should be noted that the detection tube 18 is a rigid plastic tube and is arranged along the direction of the splicing sealing strip 3 at its lower part.

[0055] Please refer to Figure 8 , the opening and closing monitoring system further includes a leak monitoring module. The input end of the leak monitoring module is connected to the humidity sensor 22, the output end of the leak monitoring module is connected to the control module, the output end of the control module is further connected to a detection module, and the output end of the detection module is connected to the blower 19.

[0056] Specifically, when a leak is found, the alarm module gives an alarm to remind the operator to take leak repair measures in time to reduce cargo losses.

[0057] Please refer to Figure 12 , a check valve 24 is provided in the exhaust pipe 23.

[0058] Specifically, by providing the check valve 24, the water vapor in the external airflow cannot enter the detection cylinder 21 through the exhaust pipe 23 to interfere with the detection result. In addition, it should be noted that when the data analysis module finds that the real-time humidity detected by the humidity sensor 22 exceeds the set humidity threshold, the control terminal increases the operating power of the blower 19 to accelerate the drainage of moisture at the splicing seam position and further reduce the amount of water entering the cargo hold.

[0059] Combined with the current actual requirements, the above-mentioned implementation method adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
