Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level detection device. Background Art

[0002] In order to prevent floods or monitor the water level of rivers, ponds and reservoirs, water level gauges are usually set up in conspicuous places in the river to remind people of the water level. Existing water level gauges need to be observed with the naked eye, which is difficult to observe in bad weather. In addition, in rapids, the specific water level will be blurred by large waves, leading to misjudgment by observers.

When the waves are large, the device can still reduce the shaking amplitude of the inflatable floating board through the action of the stabilizing structure and the support rod, thereby reducing the difficulty of observation when the waves are large.

[0004] However, long-term direct impact of water flow will affect the structural stability of the above-mentioned device, which has already been damaged. Moreover, because the sliding rod of the above-mentioned device is in direct contact with the weakened waves, it will continue to fluctuate up and down due to the influence of the waves, which will still affect the difficulty of observing the water level.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Example

[0031] Please refer to Figure 1-Figure 7 The utility model provides a water level detection device, including a fixing seat 1, a scale plate 2, a driving component, a detection chamber 4, an elastic component, a wave-blocking chamber plate 6, a wave-blocking member, a mounting plate 11, a second water-permeable hole 63, a protective frame 71, and a rotating fan wheel 72.

[0032] Furthermore, a sliding groove is penetrated on the fixed seat 1, and a scale plate 2 is slidably arranged in the sliding groove. A driving component is arranged on the fixed seat 1, and the scale plate 2 is driven by the driving component to move relative to the fixed seat 1. The fixed seat 1 is connected to a water level detection structure.

[0033] Scale lines are arranged on the surface of the scale plate 2, and a mounting plate 11 is arranged on the fixing seat 1, which is used to install the entire device on different water surface structures (such as bridges, dams and other water surface facilities). The bottom of the scale plate 2 is sunk into the water, and the scale plate 2 is driven by the driving component to move to different water depths. The distance between the bottom of the scale plate 2 and the fixing seat 1 is set according to different water level detection requirements.

[0034] It is worth noting that when used for detecting shallow water levels, the bottom of the scale plate 2 can be directly inserted into the bottom of the water, and the scale on the scale plate 2 is used to directly display the current water depth; when used for detecting deeper water levels, the bottom of the scale plate 2 can contact the water surface, and the scale on the scale plate 2 is used to display the height after the water level rises during subsequent water rise.

[0035] Furthermore, a detection chamber 4 is fixedly connected to the fixed seat 1, and the interior of the detection chamber 4 is a cavity. A scale sub-plate 5 is slidably penetrated on the top of the detection chamber 4, and the sliding direction of the scale sub-plate 5 is consistent with the sliding direction of the scale plate 2. A buoyancy block 51 is fixedly installed on the bottom of the scale sub-plate 5. The buoyancy block 51 is hollow inside and has buoyancy. The buoyancy block 51 matches and fits with the shape of the cavity inside the detection chamber 4, and a plurality of first water-permeable holes 41 are provided on the bottom surface of the detection chamber 4.

[0036] The cavity in the detection chamber 4 is connected with the external water flow through the first water permeable hole 41. When the water level rises to the height position of the detection chamber 4, the water flows into the bottom of the cavity of the detection chamber 4 through the first water permeable hole 41, and the water flows in contact with the buoyancy block 51. The buoyancy block 51 generates buoyancy. As the water level rises, the buoyancy block 51 also moves up accordingly in the cavity of the detection chamber 4, driving the scale sub-plate 5 to slide up. A scale mark 52 is set on the top of the scale sub-plate 5. The scale mark 52 is marked with a significant color. The upward movement of the scale mark 52 will correspond to different scale lines on the scale plate 2, which is convenient for the staff to observe the current rising water level scale.

[0037] In addition, a ventilation column 42 is fixedly installed on the top surface of the detection chamber 4. The top surface of the ventilation column 42 is preferably elliptical or conical. The top surface of the ventilation column 42 is penetrated by a through hole, which is connected to the chamber inside the detection chamber 4. The through hole makes the upper cavity isolated by the buoyancy block 51 in the detection chamber 4 communicate with the external environment to ensure that the air pressure remains unchanged and the buoyancy block 51 can continue to move upward. The top surface of the ventilation column 42 is set as an inclined surface to prevent rainwater from accumulating on the top surface of the ventilation column 42 and entering into the upper cavity of the detection chamber 4 through the through hole, affecting the buoyancy rise of the buoyancy block 51, thereby affecting the water level detection accuracy.

[0038] Furthermore, a wave-blocking cavity plate 6 is connected to the detection chamber 4, and each surface of the wave-blocking cavity plate 6 is connected to the detection chamber 4 by an elastic component. A plurality of second water-permeable holes 63 are provided on the bottom surface of the wave-blocking cavity plate 6. The wave-blocking cavity plate 6 covers all surfaces of the detection chamber 4 except the top surface. The external water flow first contacts the wave-blocking cavity plate 6, and then flows into the wave-blocking cavity plate 6 through the second water-permeable holes 63 on the bottom surface of the wave-blocking cavity plate 6 to contact the detection chamber 4.

[0039] Preferably, when flooding occurs, the water level rises suddenly and rapidly, and turbulent waves are generated. When the waves hit the surface of the wave-blocking cavity plate 6, the wave-blocking cavity plate 6 is elastically displaced through the elastic member to offset part of the impact of the water flow, and the second water-permeable holes 63 on the bottom surface allow the water flow to enter and contact the detection chamber 4 only from the bottom surface of the wave-blocking cavity plate 6, further reducing the impact of side waves on the water flow entering the wave-blocking cavity plate 6, ensuring that the water flow in the wave-blocking cavity plate 6 is in a relatively stable state. After the stable water flow enters the detection chamber 4, the rising stability of the buoyancy block 51 can be guaranteed, thereby ensuring the accuracy of water level detection.

[0040] In a specific embodiment, the elastic member is preferably configured as a spring 64 .

[0041] Furthermore, a plurality of wave-blocking members are fixedly mounted on the outer wall of the wave-blocking cavity plate 6. The wave-blocking members are umbrella-shaped and are evenly arranged on the entire side of the wave-blocking cavity plate 6. There are gaps between the umbrella-shaped ends of the wave-blocking members.

[0042] Preferably, the umbrella-shaped opening end of the wave-blocking member faces the wall of the wave-blocking cavity plate 6. When the wave hits the outer wall of the wave-blocking cavity plate 6, it will first contact the umbrella-shaped end of the wave-blocking member, and then be diverted by the tip of the umbrella, flow into the gap between multiple umbrella-shaped ends, and flow between the umbrella-shaped opening end and the outer wall of the wave-blocking cavity plate 6. In this process, the direction of the water flow is changed many times and will not directly hit the outer wall of the wave-blocking cavity plate 6, thereby reducing the impact force of the water flow.

[0043] In a specific embodiment, the wave-blocking member is preferably configured as a first wave-blocking plate 61 and a second wave-blocking plate 62, and the first wave-blocking plate 61 and the second wave-blocking plate 62 are fixedly installed on the side of the fixing seat 1, and a second wave-blocking plate 62 is provided between every two first wave-blocking plates 61, and the umbrella-shaped end of the second wave-blocking plate 62 is located in front of the umbrella-shaped ends of the two first wave-blocking plates 61, respectively covering one side of the umbrella-shaped ends of the two first wave-blocking plates 61, and there is a gap between the umbrella-shaped ends of the first wave-blocking plate 61 and the second wave-blocking plate 62.

[0044] Preferably, the waves will hit the umbrella-shaped tip of the second wave-breaking plate 62 and then be diverted. The diverted water flow will contact the umbrella-shaped tip of the first wave-breaking plate 61, be diverted once again, and then flow into the gap between the wave-breaking parts. By changing the flow direction of the water flow multiple times, the impact force of the water flow is reduced.

[0045] Furthermore, a protective frame 71 is fixedly installed at the bottom of the wave-blocking cavity plate 6, and a plurality of through holes are provided on the protective frame 71. At least one rotating fan wheel 72 is rotatably installed on the protective frame 71. The blades of the rotating fan wheel 72 are in close contact with the bottom surface of the wave-blocking cavity plate 6, and the rotating fan wheel 72 is located between the protective frame 71 and the bottom surface of the wave-blocking cavity plate 6.

[0046] When the water level rises, the rapid current will generally carry mud and sand with it. When the water flows into the wave-blocking cavity plate 6 through the second water-permeable holes 63, the mud and sand will be filtered out by the second water-permeable holes 63. However, excessive mud and sand will accumulate at the second water-permeable holes 63 after being filtered, thereby blocking the second water-permeable holes 63 and affecting the water flow entering the detection chamber 4 inside the wave-blocking cavity plate 6.

[0047] Preferably, when the rapid current at the bottom of the wave-breaking cavity plate 6 passes through the second water-permeable hole 63, it will drive the rotating fan wheel 72 to rotate. When the rotating fan wheel 72 rotates, the blades thereon are in sliding contact with the bottom surface of the wave-breaking cavity plate 6, and the filtered and accumulated mud and sand are pushed away from the second water-permeable hole 63, thereby ensuring the smooth flow of the second water-permeable hole 63. While the rotating fan wheel 72 rotates, the impact force of the water flow can be relatively weakened; the through holes on the protective frame 71 can intercept larger debris entrained in the rapid current while ensuring that the water flow contacts the rotating fan wheel 72 normally, thereby preventing the debris from colliding with the rotating fan wheel 72 and causing damage to it.

[0048] In a specific embodiment, the driving assembly includes a rack 31, a first gear 32, a second gear 33, and a rotating handle 34.

[0049] Specifically, a rack 31 is fixedly connected to the scale plate 2, and the length direction of the rack 31 is consistent with the length direction of the scale plate 2. The rack 31 is meshed with a first gear 32, and the first gear 32 is meshed with a second gear 33. The first gear 32 and the second gear 33 are both rotatably set on the fixed base 1, and a rotating handle 34 is fixedly installed on the second gear 33.

[0050] When adjusting the position of the scale plate 2 relative to the fixing base 1 , the rotating handle 34 is rotated to drive the scale plate 2 to move in the sliding groove of the fixing base 1 through the meshing connection of the second gear 33 , the first gear 32 and the rack 31 .

[0051] In a specific embodiment, a signal sensing component is also included. The signal sensing component is arranged on the detection chamber 4 and includes a contact sensor 81, a communication box 82, and an alarm terminal.

[0052] Specifically, at least one contact sensor 81 is provided on the side wall of the detection chamber 4, the sensing head of the contact sensor 81 is located in the chamber of the detection chamber 4, the contact sensor 81 is connected to the communication box 82 through an electrical signal, the communication box 82 is fixedly installed on the detection chamber 4, and the communication box 82 is remotely connected to the alarm terminal through a signal.

[0053] When the water level rises, the buoyancy block 51 moves upward in the cavity of the detection chamber 4 due to the buoyancy. When it moves to the preset alarm water level, it will contact the sensing head of the contact sensor 81 set at this height, so that the contact sensor 81 sends a detection electrical signal to the communication box 82. The communication box 82 receives the electrical signal and then transmits the signal remotely to the alarm terminal. The alarm terminal issues a warning, thereby reminding the staff to know the water level situation in time.
