Description

Technical Field

[0001] This utility model relates to the field of lock water surface detection technology, specifically a lock water surface detection device. Background Technology

[0002] As vital arteries for inland waterway transportation, locks play a crucial role in regulating water levels and facilitating ship navigation. During lock operation, water conditions are complex and constantly changing. Factors such as water level fluctuations, water flow speed and direction, and the presence of floating debris all impact the safety of ship navigation and the stable operation of lock facilities.

[0003] A lock is a type of navigation structure. It is a box-shaped structure consisting of upstream and downstream approach channels and upstream and downstream lock heads connected to lock chambers. The lock chamber is a box-shaped room for mooring ships. By filling or emptying water in the chamber, the water level in the lock chamber is adjusted, allowing ships to rise and fall vertically between the upstream and downstream water levels, thus passing through the concentrated water level difference of the channel.

[0004] Regarding the existing related technologies, the inventor believes that there are the following defects: When conducting water level detection in locks, the existing technologies generally rely on workers to observe whether the water level has reached the critical value in real time. When the water level reaches the designated height, the workers open the lock. The workers need to pay attention to the water level at all times, which can easily lead to mental fatigue and decreased concentration, thereby increasing the risk of operational errors. Utility Model Content

[0005] To address the technical problem that existing staff need to constantly monitor water levels, leading to mental fatigue, decreased concentration, increased risk of operational errors, and high stress, this utility model provides a lock water level detection device.

[0006] This utility model is achieved using the following technical solution: a lock water surface detection device, comprising a lock body and a fixed cylinder, wherein the fixed cylinder is fixedly connected to one side of the lock body, a scale is fixedly connected to the top of the fixed cylinder, a float is movably connected inside the fixed cylinder, a fixed rod is fixedly connected to the top of the float, a pointer is fixedly connected to the top of the fixed rod, a conductive block is fixedly connected to one end of the pointer, the pointer is located on one side of the scale, and an alarm light is fixedly connected to the top of the scale;

[0007] The lock body has a power supply board fixedly connected to one side, which is electrically connected to the alarm light. A first connecting plate is fixedly connected to the top of the power supply board. A movable plate is hinged to one end of the first connecting plate. A first return spring is provided at the bottom end of the movable plate. A second connecting plate is fixedly connected to the bottom of the power supply board. A contact rod is movably connected inside the second connecting plate. A groove is machined on one side of the top of the fixed rod. One end of the contact rod is movably connected inside the groove.

[0008] Preferably, two locking blocks are fixedly connected to both ends of the float plate, and two locking grooves are machined on both sides of the fixed cylinder, with the locking blocks movably connected inside the locking grooves.

[0009] Preferably, a guide plate is fixedly connected to the top of the fixed cylinder, and the fixed rod is movably connected inside the guide plate.

[0010] Preferably, one end of the first reset spring is fixedly connected to one end of the first connecting plate, and the other end of the first reset spring is fixedly connected to the bottom of the movable plate.

[0011] Preferably, the second connecting plate has a groove machined inside, and one end of the contact rod is fixedly connected to a fixing ring, which is movably connected inside the groove.

[0012] Preferably, a second return spring is provided on the outside of the contact rod, one end of the second return spring is fixedly connected to one side of the fixing ring, and the other end of the second return spring is fixedly connected to one side of the inner wall of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When this utility model is in use, as the water level inside the gate chamber rises, the buoyancy of the water will cause the float to move upward, which in turn will cause the fixed rod and pointer to move upward, so that the pointer points to different scales as the water level rises, making it convenient to know the water level height in a timely manner.

[0015] When this utility model is in use, when the fixed rod moves upward, the contact rod at one end of the second connecting plate is in contact with the fixed rod. At the same time, the contact rod will move along the inside of the slide groove. When the fixed rod drives the conductive block to move upward and contact the movable plate, the two poles of the power supply inside the power board are connected to form a closed circuit through the fixed rod. Current will be generated in the circuit, thereby energizing the alarm light and emitting an alarm, so that the staff can know in time that the water level has reached the predetermined height. The operation is simple and convenient. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1: Please refer to Figure 1 - Figure 5 This embodiment of a lock surface detection device includes a lock body 1 and a fixed cylinder 2. The fixed cylinder 2 is fixedly connected to one side of the lock body 1. A scale 3 is fixedly connected to the top of the fixed cylinder 2. A float 4 is movably connected inside the fixed cylinder 2. A fixed rod 5 is fixedly connected to the top of the float 4. A pointer 9 is fixedly connected to the top of the fixed rod 5. A conductive block 10 is fixedly connected to one end of the pointer 9. The pointer 9 is located on one side of the scale 3. An alarm light 15 is fixedly connected to the top of the scale 3. The lock body 1 is fixedly located on one side of the scale 3. A power board 11 is fixedly connected to the alarm light 15. A first connecting plate 12 is fixedly connected to the top of the power board 11. A movable plate 13 is hinged to one end of the first connecting plate 12. A first return spring 14 is provided at the bottom end of the movable plate 13. A second connecting plate 16 is fixedly connected to the bottom of the power board 11. A contact rod 17 is movably connected inside the second connecting plate 16. A groove 18 is machined on one side of the top of the fixed rod 5. One end of the contact rod 17 is movably connected inside the groove 18.

[0024] When the water level inside the sluice chamber rises, the buoyancy of the water will cause the float plate 4 to move upward, the float plate 4 will cause the fixed rod 5 to move upward, and the fixed rod 5 will cause the pointer 9 to move upward, so that the pointer 9 points to different scales as the water level rises, making it convenient to know the water level height in a timely manner.

[0025] Secondly, the fixed rod 5 is made of conductive material. When the fixed rod 5 moves upward, the contact rod 17 at one end of the second connecting plate 16 will contact the fixed rod 5 and move along the inside of the slide groove 18. When the fixed rod 5 drives the pointer 9 and the conductive block 10 to move upward and contact the movable plate 13, the two poles of the power board 11 are connected through the fixed rod 5. When the two poles of the power supply inside the power board 11 are connected to form a closed circuit, current will be generated in the circuit, thereby energizing the alarm light 15 to sound an alarm, making it convenient for staff to know in time that the water level has reached the predetermined height. The operation is simple and convenient.

[0026] Furthermore, two locking blocks 6 are fixedly connected to both ends of the float plate 4, and two locking grooves 7 are machined on both sides of the fixed cylinder 2. The locking blocks 6 are movably connected inside the locking grooves 7. When the float plate 4 moves upward, the float plate 4 will drive the locking blocks 6 to move upward. The locking blocks 6 will move along the inside of the locking grooves 7. The locking grooves 7 will limit the movement of the locking blocks 6, so that the float plate 4 remains stable when it moves upward.

[0027] Furthermore, a guide plate 8 is fixedly connected to the top of the fixed cylinder 2, and the fixed rod 5 is movably connected inside the guide plate 8. By providing the guide plate 8, when the float 4 drives the fixed rod 5 to move upward, the fixed rod 5 moves along the inside of the guide plate 8, and the guide plate 8 will guide the movement of the fixed rod 5, so that the fixed rod 5 moves in the vertical direction.

[0028] Furthermore, one end of the first reset spring 14 is fixedly connected to one end of the first connecting plate 12, and the other end of the first reset spring 14 is fixedly connected to the bottom of the movable plate 13. With the first reset spring 14 provided, when the conductive block 10 moves upward and presses and lifts the movable plate 13, the movable plate 13 will rotate upward around one end of the first connecting plate 12, and at the same time the first reset spring 14 will extend. When the conductive block 10 moves downward and disengages from the movable plate 13, the first reset spring 14 will retract and revert to its original position, thereby driving the movable plate 13 to revert to its original position.

[0029] Furthermore, the second connecting plate 16 has a groove 19 machined inside, one end of the contact rod 17 is fixedly connected to a fixing ring 21, the fixing ring 21 is movably connected inside the groove 19, and a second return spring 20 is provided on the outside of the contact rod 17. One end of the second return spring 20 is fixedly connected to one side of the fixing ring 21, and the other end of the second return spring 20 is fixedly connected to one side of the inner wall of the groove 19.

[0030] Since the second return spring 20 is always in an extended state, the elastic force of the second return spring 20 will drive the fixed ring 21 to move closer to the second return spring 20. The fixed ring 21 will drive the contact rod 17 to move, so that one end of the contact rod 17 is always in contact with the inside of the slide groove 18.

[0031] Working principle: When the water level inside the gate chamber rises, the buoyancy of the water will drive the float plate 4 to move upward. The float plate 4 will drive the fixed rod 5 and the pointer 9 to move upward, so that the pointer 9 points to different scales as the water level rises, making it convenient to know the water level in time. When the fixed rod 5 moves upward, the contact rod 17 at one end of the second connecting plate 16 is in contact with the fixed rod 5. At the same time, the contact rod 17 will move along the inside of the slide groove 18. When the fixed rod 5 drives the conductive block 10 to move upward and contact the movable plate 13, the two poles of the power supply inside the power board 11 are connected to form a closed circuit through the fixed rod 5. Current will be generated in the circuit, so that the alarm light 15 will be powered on and an alarm will be sounded, making it convenient for staff to know in time that the water level has reached the predetermined height. The operation is simple and convenient.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
