Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dam water level monitoring, and particularly relates to a warning device for dam water level monitoring. BACKGROUND

[0002] Reservoir dams bring many practical benefits to human beings in terms of comprehensive benefits such as irrigation, flood control and power generation, but also have a fundamental impact on immigrants, river courses, water quality, aquatic organisms and river banks, and dam collapse can even cause serious secondary disasters.

[0003] At present, when monitoring the dam water level, a liquid level sensor needs to be used, and the traditional liquid level sensor needs to be connected to the dam water level tank through hard wiring. Once a problem occurs, it is very difficult to repair, and even the entire system needs to be reinstalled. Moreover, the liquid level sensor installed in the water tank is not convenient for workers to replace.

[0004] Therefore, we provide a warning device for dam water level monitoring to solve the above problems. SUMMARY

[0005] The purpose of the application is to provide a warning device for dam water level monitoring, which drives the driving gear to rotate the rotating disc by starting the driving motor. When the rotating disc rotates, the connecting rod will be moved through the guide groove, and the clamping block will be moved, thereby completing the replacement of the radar water level gauge, solving the problem of inconvenient replacement of the existing liquid level sensor.

[0006] To solve the above technical problems, the application is realized by the following technical scheme: The application is a warning device for dam water level monitoring, which includes a monitoring component, a containing box, a radar water level gauge arranged inside the containing box, a sound and light alarm fixed to the top end of the containing box, an observation window arranged on the front side of the containing box, a drainage cylinder arranged at the bottom end of the containing box, and a float arranged inside the drainage cylinder. The replacement component includes a limiting assembly arranged inside the containing box, a driving assembly arranged on the containing box, a rotating assembly arranged inside the limiting assembly, and a clamping assembly arranged inside the rotating assembly. The driving assembly drives the rotating assembly, and the limiting assembly is moved through the limiting action of the rotating assembly to install and fix the radar water level gauge. The fixing component includes a receiving assembly arranged on the side wall of the observation window and a fixing assembly arranged inside the receiving assembly. The fixing assembly is arranged inside the receiving assembly to fix the observation window.

[0007] The application further provides that the limiting assembly comprises a limiting groove arranged in the inner part of the containing box, a fixed disc arranged in the limiting groove, and a limiting slot arranged on the top of the fixed disc.

[0008] The application further provides that the driving assembly comprises a driving motor arranged on the inner wall of the containing box, a driving shaft fixed on the driving end of the driving motor, and a driving gear fixed on the bottom end of the driving shaft.

[0009] The application further provides that the rotating assembly comprises a rotating disc arranged on the top of the fixed disc, a guide slot arranged on the top of the rotating disc, and a connecting gear fixed on the side wall of the rotating disc.

[0010] The application further provides that the clamping assembly comprises a connecting rod arranged in the limiting slot, a clamping block fixed on the top end of the connecting rod, and a guide block fixed on the side wall of the clamping block.

[0011] The application further provides that the receiving assembly comprises a first fixed block fixed on the front side of the observation window, a second fixed block fixed on the side wall of the containing box, a through hole penetrating through the end part of the second fixed block, and a fixed hole arranged in the through hole.

[0012] The application further provides that the fixing assembly comprises a fixed sleeve fixed in the first fixed block, a pressing rod penetrating through the inner part of the fixed sleeve, a resisting plate fixed on the outer wall of the pressing rod, a spring arranged between the resisting plate and the fixed sleeve, and a limiting block fixed on the end part of the pressing rod.

[0013] The application further provides a filtering component, which comprises a filtering assembly arranged in the inner part of the drainage cylinder, and a cleaning assembly arranged on one side of the filtering assembly. The filtering assembly comprises a water inlet hole penetrating through the side wall of the drainage cylinder, a filtering plate fixed in the inner part of the water inlet hole, and a connecting plate fixed in the inner part of the drainage cylinder, wherein the connecting plate is symmetrical about the center line of the water inlet hole.

[0014] The application further provides that the cleaning assembly comprises a brush arranged in the inner part of the connecting plate, a connecting gear fixed on the outer wall of the brush, and a toothed plate arranged on one side of the connecting gear. The connecting gear and the toothed plate are engaged with each other, and the toothed plate is fixedly connected to the bottom of the float.

[0015] The application has the following advantages: 1. This invention starts a drive motor, which drives a drive gear to rotate via a drive shaft. The drive gear meshes with a connecting gear, so that when the drive gear rotates, it drives a rotating disk to rotate. Then, by utilizing the cooperation of the guide groove, the limiting groove and the connecting rod, the locking block is moved, so that the locking block engages or disengages from the radar level gauge, thereby completing the replacement of the radar level gauge.

[0016] 2. In this invention, pressing the pressing rod moves the limiting block through the through hole to the other side of the second fixing block. Then, the pressing rod is rotated to make the limiting block coincide with the fixing hole. Then, the pressing rod is released, and the spring force is used to push the pressing rod back to its original position, so that the limiting block is locked inside the fixing hole, thereby completing the fixing of the observation window and protecting the radar water level gauge.

[0017] 3. In this invention, the movement of the buoy drives the toothed plate to move, and the movement of the toothed plate drives the connecting gear to rotate. The locking block is connected to the brush. Therefore, when the connecting gear rotates, it will drive the brush to rotate, cleaning the filter plate and preventing the observation window from being blocked.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1 Please see Figures 1-4This invention relates to an early warning device for dam water level monitoring, comprising a monitoring component 100, including a housing 101, a radar water level gauge 106 disposed inside the housing 101, an audible and visual alarm 103 fixed to the top of the housing 101, an observation window 104 disposed on the front side of the housing 101, a diversion tube 102 disposed at the bottom of the housing 101, and a buoy 105 disposed inside the diversion tube 102; and a replacement component 200, including a limiting component 201 disposed inside the housing 101, a driving component 202 disposed on the housing 101, a rotating component 203 disposed inside the limiting component 201, and a locking component 204 disposed inside the rotating component 203; wherein, the driving component 202 drives the rotating component 203, and the limiting component 201 moves due to the limiting effect of the rotating component 203, thereby installing and fixing the radar water level gauge 106.

[0031] Specifically, the limiting component 201 includes a limiting groove 201a opened inside the receiving box 101, a fixed disk 201b disposed inside the limiting groove 201a, and a limiting groove 201c opened on the top of the fixed disk 201b. The limiting groove 201c is distributed circumferentially along the fixed disk 201b, and the fixed disk 201b is fixed to the receiving box 101. The driving component 202 includes a driving motor 202a disposed on the inner wall of the receiving box 101, a driving shaft 202b fixed to the driving end of the driving motor 202a, and a driving gear 202c fixed to the bottom end of the driving shaft 202b. The driving motor 202a is fixed to the inner bottom side of the receiving box 101, and the driving shaft 202b and the driving gear 202c are fixed to each other.

[0032] Furthermore, the rotating assembly 203 includes a rotating disk 203a disposed on the top of the fixed disk 201b, a guide groove 203b formed on the top of the rotating disk 203a, and connecting teeth 203c fixed to the side wall of the rotating disk 203a. The rotating disk 203a rotates relative to the receiving box 101, and the connecting teeth 203c are fixedly connected to the outer wall of the rotating disk 203a. The connecting teeth 203c mesh with the drive gear 202c, and the rotation of the drive gear 202c drives the rotating disk 203a to rotate. The guide groove 203b is circumferentially distributed on the outer wall of the rotating disk 203a. The engaging assembly 204 includes a rotating disk 203a disposed on the top of the fixed disk 201b, a guide groove 203b formed on the top of the rotating disk 203a, and connecting teeth 203c fixed to the side wall of the rotating disk 203a. The limiting groove 201c contains a connecting rod 204a, a locking block 204b fixed to the top of the connecting rod 204a, and a guide block 204c fixed to the side wall of the locking block 204b. The connecting rod 204a is disposed inside the limiting groove 201c and the guide groove 203b, and the limiting groove 201c is fixedly connected to the locking block 204b. 204c is fixedly connected to both sides of the outer wall of the limiting groove 204a, and the 204c is slidably connected inside the limiting groove 201a. When the rotating disk 203a rotates, it will drive the connecting rod 204a to move. Under the restriction of the limiting groove 201c, the connecting rod 204a can only move laterally to prevent deflection.

[0033] The operation process of this embodiment is as follows: First, the drive motor 202a is started by the corresponding controller. Under the drive of the drive motor 202a, the drive shaft 202b is rotated. As the drive shaft 202b rotates, the drive gear 202c rotates. The drive gear 202c meshes with the connecting gear 203c, and the connecting gear 203c is fixed on the outer wall of the rotating disk 203a. Thus, when the drive gear 202c rotates, it can drive the rotating disk 203a to rotate through the connecting gear 203c. In addition, the rotating disk 203a... When a rotates, the angle of the guide groove 203b changes, causing the connecting rod 204a to move. The movement of the connecting rod 204a is restricted by the limiting groove 201c, so that the connecting rod 204a can only move laterally and will not rotate. The connecting rod 204a is fixedly connected to the locking block 204b, so that the locking block 204b will move during the movement of the connecting rod 204a. The two sides of the locking block 204b are fixedly connected to 204c, which further restricts the movement direction of the locking block 204b.

[0034] Example 2 Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 Based on Embodiment 1, the fixing component 300 includes a receiving component 301 disposed on the side wall of the observation window 104 and a fixing component 302 disposed inside the receiving component 301.

[0035] Specifically, the receiving component 301 includes a first fixing block 301a fixed to the front side of the observation window 104, a second fixing block 301b fixed to the side wall of the receiving box 101, a through hole 301c penetrating the end of the second fixing block 301b, and a fixing hole 301d opened inside the through hole 301c. The first fixing block 301a is fixedly connected to the front side of the observation window 104, and the second fixing block 301b is fixedly connected to the side wall of the receiving box 101, with its position corresponding to that of the first fixing block 301a.

[0036] Furthermore, the fixing assembly 302 includes a fixing sleeve 302a fixed inside the first fixing block 301a, a pressing rod 302b penetrating inside the fixing sleeve 302a, a baffle plate 302c fixed to the outer wall of the pressing rod 302b, a spring 302d disposed between the baffle plate 302c and the fixing sleeve 302a, and a limiting block 302e fixed to the end of the pressing rod 302b. The fixing sleeve 302a is fixed inside the first fixing block 301a, while the fixing... The sleeve 302a has a sliding connection to a baffle plate 302c, and the two ends of the spring 302d are fixed to the baffle plate 302c and the inside of the fixed sleeve 302a respectively. In addition, a baffle plate 302c is fixedly connected inside the baffle plate 302c, and the spring 302d passes through the end of the fixed sleeve 302a. A limiting block 302e is fixedly connected to the end of the pressing rod 302b, and the shape of the limiting block 302e matches the shape of the second fixed block 301b and the through hole 301c.

[0037] The operation process of this embodiment is as follows: Press the pressing rod 302b. At this time, the spring 302d is pulled by the baffle plate 302c, causing the spring 302d to deform. Then, the pressing rod 302b will push out the limiting block 302e, and the limiting block 302e will move to the outside of the second fixing block 301b through the through hole 301c. Then, rotate the pressing rod 302b so that the limiting block 302e is parallel to the fixing hole 301d. Then, release the pressing rod 302b and use the reset action of the spring 302d to pull the pressing rod 302b back to its original position, so that the limiting block 302e is inserted into the interior of the fixing hole 301d, thus completing the fixing of the observation window 104.

[0038] Example 3 Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 Based on Embodiments 1 and 2, it also includes a filter component 400, which includes a filter assembly 401 disposed inside the flow guide tube 102 and a cleaning assembly 402 disposed on one side of the filter assembly 401. The filter assembly 401 includes a water inlet hole 401a penetrating through the side wall of the diversion tube 102, a filter plate 401b fixed inside the water inlet hole 401a, and a connecting plate 401c fixed inside the diversion tube 102. The connecting plate 401c is symmetrical about the center line of the water inlet hole 401a. Water inlets 401a are provided on both sides of the diversion tube 102, and the filter plate 401b is fixedly connected inside the water inlet hole 401a. The water is filtered by the filter plate 401b to prevent impurities from entering the interior of the diversion tube 102, which would prevent the float 105 from moving normally and affect the monitoring results.

[0039] Specifically, the cleaning component 402 includes a brush 402a disposed inside the connecting plate 401c, a connecting gear 402b fixed to the outer wall of the brush 402a, and a toothed plate 402c disposed on one side of the connecting gear 402b; wherein the connecting gear 402b and the toothed plate 402c mesh with each other, the toothed plate 402c is fixedly connected to the bottom of the buoy 105, the connecting plate 401c is fixedly connected to the guide tube 102, and the brush 402a is fixedly connected to the connecting plate 401c. c is a rotating connection, and the rotation of the connecting plate 401c extends to the outside of the connecting plate 401c. The connecting plate 401c is fixedly connected to the connecting gear 402b. When the connecting gear 402b meshes with the toothed plate 402c, when the radar level gauge 106 is lifted by buoyancy, it will drive the toothed plate 402c to move upward and rotate, which in turn drives the brush 402a to rotate, thereby cleaning the connecting plate 401c and preventing the connecting plate 401c from being blocked.

[0040] The operation process of this embodiment is as follows: When water enters the interior of the diversion tube 102 through the inlet hole 401a, the float 105 is buoyed and rises, driving the toothed plate 402c to move. When the toothed plate 402c moves, it drives the connecting gear 402b to rotate, cleaning the filter plate 401b. In addition, the water entering the diversion tube 102 lifts the float 105, and then the radar water level gauge 106 monitors the position of the float 105, thereby indirectly achieving the purpose of water level monitoring. When the water level reaches the warning value, the signal is transmitted to the audible and visual alarm 103 to sound an alarm, thereby reminding the staff and achieving the purpose of early warning.
