Description

Technical Field

[0001] The utility model relates to the technical field of ship monitoring, in particular to a device for ship height monitoring suitable for a lifting type lock on a road ship lock. Background Art

[0002] With the development of water conservancy construction in my country, many water conservancy hub projects have been built on the main rivers in my country. In order to facilitate water transportation, water conservancy hub projects have correspondingly built new ship lock buildings. At the same time, in order to facilitate the passage of management personnel, etc., ship lock roads have also been built on the ship lock buildings.

[0003] However, with the development of water transportation, the demand for large ships to pass through locks has become increasingly obvious, which often leads to the problem of ships being too high and easily colliding with the roads above the locks.

[0004] In the prior art, in order to detect the excessive height of a ship, the technical means adopted are all laser beam solutions, that is, the laser beam device and the laser receiving device are at a fixed height and kept flush with the road on the lock; in this way, when a ship passes by, if it exceeds the height, the laser transmission-receiving path will be cut off, thereby sounding an alarm.

[0005] The existing technology can measure whether a ship is too high without stopping the ship, and it is simple and easy to operate; however, the defects of the existing technology are:

[0006] Since the existing technology is aimed at the construction of lock buildings on large rivers; such large lock buildings are generally very high, and the road on the lock is fixed; therefore, it is only necessary to simply align the elevation of the road on the lock with the height of the laser shooting solution, and there is no need to measure the specific height of the ship, only to know whether it is too high.

[0007] However, in addition to a large number of ship locks built on large rivers, my country also has a large number of ship locks built on small and medium-sized rivers. In order to save construction costs, most of these small and medium-sized ship locks adopt a lifting scheme, that is, when there are no ships passing, the lock road is lowered and traffic on both sides is normal. When a ship passes, traffic on both sides is suspended and the lock road is raised until the ship passes and then lowered;

[0008] Under this demand, the existing technology cannot play a role. This is because there is no fixed height for the lifting road on the lock, and it is impossible to use a fixed laser shooting solution to monitor the road on the lock. Therefore, especially for the lock management unit with the lifting function of the lock road, it is urgent to accurately measure the height of the ship and plan the lifting height of the road on the lock in advance before the ship enters the lock. Utility Model Content

[0009] In view of the above problems, the utility model provides a device for monitoring the ship height of a lifting type lock road ship lock, the purpose of which is to allow the lock management unit to plan the lifting height of the lock road in advance before the ship enters the lock, and to reduce the error caused by different draft depths caused by the ship load.

[0010] In order to solve the above problems, the technical solution provided by the utility model is:

[0011] A device for monitoring the height of a ship on a lifting lock road ship lock, comprising an upright pole, an alarm module, a laser detector, a radar water level gauge, a main control module, a video acquisition module, and a lifting platform; wherein:

[0012] The upright pole is arranged on a pier upstream of a lock structure through which a ship to be measured in height is about to pass, and is perpendicular to a horizontal plane;

[0013] The lifting platform performs lifting movement along the extension direction of the upright rod;

[0014] The laser detector is installed on the upper end surface of the lifting platform, and the direction of the emitted laser is parallel to the horizontal plane;

[0015] The video acquisition module is installed at the top of the upright pole, and the direction of video acquisition is toward the ship whose height is to be measured;

[0016] The radar water level meter is used to measure and record the water level elevation at the current moment in real time; the radar water level meter is installed below the video acquisition module and is higher than the maximum rising elevation of the lifting platform; the emission direction of the radar water level meter points to the water surface.

[0017] Preferably, the upright pole is fixedly connected to a utility pole provided on the mooring pier and is parallel to the utility pole.

[0018] Preferably, the upright rod is provided with a guide rail along the extension direction of the rod for guiding the lifting platform to perform lifting movement.

[0019] Preferably, the upright pole is also provided with a scale for characterizing the laser elevation along the extension direction of the pole; the laser elevation is used to characterize the elevation of the laser detector; the measuring range of the scale of the upright pole is higher than the maximum rising elevation of the lower end surface of the road on the lock building; the reference elevation of the laser elevation represented by the scale of the upright pole is the same as the reference elevation of the water level elevation.

[0020] Preferably, a moving slider is sleeved on the upright rod; the moving slider is electrically signal coupled to the main control module, and rises or falls along the guide rail under the control of the main control module.

[0021] Preferably, one side surface of the lifting platform is fixedly connected to the moving slider, and the other opposite side surface faces the ship whose height is to be measured; and the upper end surface of the lifting platform is parallel to the horizontal plane.

[0022] Preferably, the alarm module is electrically signal coupled to the main control module.

[0023] Preferably, the main control module is installed on a side of the electric pole away from the upright pole.

[0024] Compared with the prior art, the utility model has the following advantages:

[0025] 1. Since the present invention can accurately measure the current height of the ship above the water surface in real time, the ship lock management unit can plan the lifting height of the road on the ship lock in advance before the ship enters the lock;

After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0032] like Figure 1 As shown, a device for monitoring the height of a ship on a road lock of a lifting type lock comprises a vertical pole 1, an alarm module 2, a laser detector 3, a radar water level meter 4, a main control module 5, a video acquisition module 6, and a lifting platform 7; wherein:

[0033] The upright pole 1 is arranged on a pier 8 upstream of a lock structure through which a ship whose height is to be measured is about to pass, and is perpendicular to the horizontal plane.

[0034] In this specific embodiment, the upright pole 1 is fixedly connected to the electric pole provided on the mooring pier 8, and is parallel to the electric pole.

[0035] It should be noted that since there is an electric pole on the mooring pier 8, considering the stability and reducing the difficulty and cost of the construction and layout of the device, the upright pole 1 with the guide rail 9 and the scale is fixed on the electric pole.

[0036] In this specific embodiment, the upright rod 1 is provided with a guide rail 9 along the extension direction of the rod for guiding the lifting platform 7 to perform lifting movement.

[0037] In this specific embodiment, the upright pole 1 is also provided with a scale for characterizing the laser elevation along the extension direction of the pole; the laser elevation is used to characterize the elevation of the laser detector 3; the measuring range of the scale of the upright pole 1 is higher than the maximum rising elevation of the lower end surface of the road on the lock building; the reference elevation of the laser elevation represented by the scale of the upright pole 1 is the same as the reference elevation of the water level elevation.

[0038] It should be noted that the reference elevation of the laser elevation represented by the scale of the upright pole 1 is the same as the reference elevation of the water level elevation, and its purpose is to align the scale of the upright pole 1 with the real-time measurement result of the radar water level meter 4 at the actual physical elevation.

[0039] In this specific embodiment, a moving slider is sleeved on the upright rod 1 ; the moving slider is electrically signal coupled to the main control module 5 , and under the control of the main control module 5 , rises or falls along the guide rail 9 .

[0040] The lifting platform 7 performs lifting movement along the extending direction of the upright rod 1 .

[0041] In this specific embodiment, one side surface of the lifting platform 7 is fixedly connected to the moving slider, and the other opposite side surface faces the ship whose height is to be measured; the upper end surface of the lifting platform 7 is parallel to the horizontal plane.

[0042] The laser detector 3 is installed on the upper end surface of the lifting platform 7, and the direction of the emitted laser is parallel to the horizontal plane.

[0043] The video acquisition module 6 is installed at the top of the upright pole 1, and the direction of video acquisition is toward the ship whose height is to be measured.

[0044] The radar water level meter 4 is used to measure and record the water level elevation at the current moment in real time; the radar water level meter 4 is installed below the video acquisition module 6 and is higher than the maximum rising elevation of the lifting platform 7; the emission direction of the radar water level meter 4 points to the water surface.

[0045] In this specific embodiment, the alarm module 2 is electrically signal coupled to the main control module 5 .

[0046] In this specific embodiment, the laser detector 3 is electrically signal coupled to the main control module 5 .

[0047] In this specific embodiment, the video acquisition module 6 is electrically signal coupled to the main control module 5 .

[0048] In this specific embodiment, the radar water level meter 4 is electrically signal coupled to the main control module 5 .

[0049] In this specific embodiment, the main control module 5 is installed on a side of the electric pole away from the upright pole 1 .

[0050] like Figure 2 In order to further demonstrate the technical effect of the utility model, this specific embodiment also records a method for measuring the height of a ship above the water surface using the device, which is as follows:

[0051] S100. Calibrate the radar water level meter 4 for real-time measurement results so that the reference elevation of the water level is the same as the reference elevation of the laser elevation represented by the scale of the upright pole 1, that is, align the scale of the upright pole 1 with the real physical elevation.

[0052] S200. The video acquisition module 6 continuously acquires video data at the mooring pier 8 and transmits the video data back to the main control module 5 in real time.

[0053] S300. The main control module 5 identifies the transmitted video data frame by frame until it determines that the ship to be measured has been moored at the mooring pier 8 and is waiting for inspection; then executes S400.

[0054] S400. The main control module 5 controls the laser detector 3 to perform a sector scan in the horizontal direction; and then performs the following operations according to the scanning results:

[0055] If the scanning result shows that the laser detector 3 detects an obstacle ahead, Sa500 is executed.

[0056] If the scanning result shows that the laser detector 3 does not detect any obstacle ahead, Sb600 is executed.

[0057] like Figure 3 As shown, it should be noted that the laser detector 3 ensures that the laser is parallel to the water surface through the lifting platform 7; at the same time, the laser detector 3 monitors whether there is an obstacle in front through mechanical rotation; the obstacle here is the hull.

[0058] It should be further explained that the laser detector 3 is a linear scan, so it needs to be rotated to form a fan; the current effective linear scanning distance of the laser detector 3 is 150m to 200m, which can achieve full coverage for ships on small rivers.

[0059] Sa500. The main control module 5 controls the alarm module 2 to send an alarm to the lock management unit, prompting the ship not to start temporarily and to stand by for further orders.

[0060] Sa510. The control slider of the main control module 5 moves upward by an artificially preset rise value; the motion slider moves upward, thereby driving the lifting platform 7 to move upward by an rise value.

[0061] In this specific embodiment, the rise value is 1 cm.

[0062] Sa520. The main control module 5 controls the laser detector 3 to perform a sector scan in the horizontal direction again; then the following operations are performed according to the scanning results:

[0063] If the scanning result shows that the laser detector 3 does not detect any obstacle ahead, S700 is executed.

[0064] If the scanning result shows that the laser detector 3 detects an obstacle ahead, the process returns to and executes Sa500 again.

[0065] Sb600. The main control module 5 controls the alarm module 2 to send out an alarm to the lock management unit, prompting the ship not to start temporarily and to stand by for further orders.

[0066] Sb610. The control slider of the main control module 5 moves downward by a manually preset descent value; the motion slider moves downward, thereby driving the lifting platform 7 to move downward by a descent value.

[0067] In this specific embodiment, the drop value is 1 cm.

[0068] Sb620. The main control module 5 controls the laser detector 3 to perform a sector scan in the horizontal direction again; then the following operations are performed according to the scanning results:

[0069] If the scanning result shows that the laser detector 3 detects an obstacle ahead, S700 is executed.

[0070] If the scanning result shows that the laser detector 3 does not detect any obstacle ahead, the process returns to and executes Sb500 again.

[0071] S700. Record the current laser elevation value; the main control module 5 controls the radar water level meter 4 to record the current water level elevation value.

[0072] S800. Subtract the water level elevation from the laser elevation to obtain the ship height; then send the ship height to the lock management unit.

[0073] S900. The ship lock management unit calculates the lowest elevation of the lock road based on the ship height, the current elevation of the lower end surface of the lock road of the ship lock building, and the maximum elevation; the lowest elevation of the lock road is calculated by adding the ship height to the elevation of the lock chamber water level and then subtracting the current elevation of the lower end surface of the lock road;

[0074] S1000. According to the relationship between the lowest rising height of the road above the gate and the maximum rising height of the road above the gate, perform the following operations:

[0075] If the minimum rise height of the road above the lock is higher than the maximum rise height of the road above the lock building, the lock management unit shall prohibit the ship from entering the lock building through an order.

[0076] If the elevation of the water level in the lock chamber plus the height of the ship is lower than the current elevation of the lower end surface of the lock road of the lock building, the lock management unit will release the ship to enter the lock building through an instruction.

[0077] If the lowest rising height of the lock road is lower than the maximum rising height of the lock road of the lock building, and the elevation of the lock chamber water level plus the current elevation of the lower end surface of the lock road that is higher than the height of the ship, the lock management unit will instruct the ship to temporarily stand by; then the lock management unit will raise the lock road of the lock building until the lower end surface of the lock road of the lock building is higher than the height of the ship; and then allow the ship to enter the lock building.

[0078] It should be noted that one of the biggest benefits of using the utility model is that the adjustment height of the road on the gate that needs to be adjusted can be accurately known; specifically:

[0079] The lock management unit knows the height of the water surface upstream of the lock. After the upstream lock chamber is opened, water rushes into the lock chamber, and the water surface height of the lock chamber is basically consistent with the upstream water surface. At the same time, the lock management unit also knows the height of the road on the lock before adjustment, and the height of the ship above the water surface. Therefore, the management unit can accurately calculate the minimum height required for adjustment.

[0080] It should be further explained that one of the biggest advantages of adopting the above-mentioned technical solution is that the specific lifting space of the lock road that needs to be adjusted can be known for each ship, without the time-consuming and laborious process of raising the entire lock road to the top, which saves a lot of time and is an essential data source for refined management work.
