Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering equipment, and specifically to a height-adjustable water level alarm device in water conservancy engineering. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. They are also called water projects. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, channels, aqueducts, raft channels, fishways, etc. to achieve their goals. Classified by purpose or service object, they can be divided into: flood control projects to prevent flood disasters; farmland water conservancy projects, also known as irrigation and drainage projects, to prevent drought, waterlogging, and waterlogging disasters for agricultural production; hydropower projects to convert water energy into electric energy; waterway and port projects to improve and create shipping conditions; urban water supply and drainage projects to serve industrial and domestic water use and treat and discharge sewage and rainwater; soil and water conservation projects and environmental water conservancy projects to prevent soil erosion and water pollution and maintain ecological balance; fishery water conservancy projects to protect and enhance fishery production; beach reclamation projects to reclaim land from the sea to meet the needs of industrial and agricultural production or transportation, etc. A water conservancy project that serves multiple goals such as flood control, irrigation, power generation, and shipping at the same time is called a comprehensive utilization water conservancy project.

[0003] For example, the patent with the patent number CN110967091B discloses a water level alarm system using a dark liquid. A water level alarm system using a dark liquid includes: a main body bracket, a solar panel, a storage battery, a wireless data transmission device, a data receiving and processing terminal, an alarm module, and a measuring device; the main body bracket is arranged above the river surface; the solar panel, the storage battery, the wireless data transmission device, the data receiving and processing terminal, and the alarm module are fixedly arranged on the main body bracket, wherein the wireless data transmission device, the data receiving and processing terminal, the alarm module, and the measuring module are all powered by the storage battery, and the data receiving and processing terminal is connected to the alarm module, and the measuring device is fixedly arranged below the main body bracket through a fixed rod. The present invention solves the problem that an alarm cannot be given in time when the water level exceeds the warning line.

[0004] Existing alarm devices generally use a sensing device to convey the water level height to the alarm device. The sensing device is prone to malfunction due to a humid environment. When the water level is too high, the sensing device cannot trigger the alarm device to send an alarm to the management personnel, resulting in the management personnel being unable to detect the rising water level in a timely manner, causing flood disasters. Moreover, when the existing alarm device is in use, birds may stay on the alarm device to perch, and the birds are likely to damage the alarm device and even trigger the alarm device, sending false information to the management personnel. Summary of the Invention

[0005] The purpose of the present invention is to provide a height-adjustable water level alarm device in a water conservancy project to solve the problem in the above-mentioned background technology that existing alarm devices generally use a sensing device to convey the water level height to the alarm device. The sensing device is prone to malfunction due to a humid environment. When the water level is too high, the sensing device cannot trigger the alarm device to send an alarm to the management personnel, resulting in the management personnel being unable to detect the rising water level in a timely manner, causing flood disasters.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A height-adjustable water level alarm device in a water conservancy project includes a scale rod. The scale rod includes a support plate and an alarm. There is a support plate provided on the top section of the scale rod, and two installation grooves are symmetrically opened on the top of the support plate. One alarm is provided in each of these two installation grooves; a switch is provided at the bottom of each of the two alarms; a buried pile is provided at the bottom end of the scale rod, and a side groove is opened on each of the left and right sides of the buried pile; a support plate is provided at the rear side of the top of the buried pile, and two rear plates are provided at the rear side of the support plate. A cross roller is rotatably installed on these two rear plates; a bevel gear is provided in the middle section of the cross roller; a floating plate is sleeved and slidably installed on the scale rod, and the floating plate is of a circular structure; a connecting plate is provided at the rear side of the support plate; a cover cylinder is provided at the top end of the scale rod, and a number of sound emitting grooves are opened on the circumferential outer wall of the cover cylinder; two fixing plates are symmetrically provided at the bottom of the support plate. These two fixing plates are of an L-shaped structure, and a telescopic rod is slidably inserted at the inner bottom of each of the two support plates.

[0007] Preferably, the buried pile includes a top plate and a binding plate. A top plate is provided at the top of the buried pile, and the top plate is of a circular structure; the bottom of the top plate is installed with a binding plate through a spring, and the binding plate is sleeved and slidably installed on the buried pile.

[0008] Preferably, the side groove includes a connecting plate and a soil fixing member. A connecting plate is installed in each of the two side grooves through a spring, and a row of soil fixing members is provided on the outer side of each of the two connecting plates; the two rows of soil fixing members are of a conical structure.

[0009] Preferably, the floating board includes floating balls. There are ten connecting blocks provided at the bottom of the floating board, and one floating ball is provided at the bottom of each of the ten connecting blocks; the ten floating balls are spherical structures.

[0010] Preferably, the cross roller includes hydraulic deflectors and cutting blades. There are two groups of hydraulic deflectors symmetrically arranged on the cross roller, and a row of cutting blades is provided at the outer end of each hydraulic deflector.

[0011] Preferably, the connecting plate includes a vertical roller and a hitting plate. A vertical roller is rotatably installed at the rear end of the top of the connecting plate, and a bevel gear is provided at the bottom end of the vertical roller, and this bevel gear meshes with the bevel gear on the cross roller; ten hitting plates are provided at the top of the vertical roller.

[0012] Preferably, the cover cylinder includes sweeping plates and cleaning brushes. Eight sweeping plates are rotatably installed at the top of the cover cylinder, and two rows of cleaning brushes are provided at the bottom of each of the eight sweeping plates.

[0013] Preferably, the telescopic rod includes a limiting plate and a top column. A limiting plate is provided at the bottom end of the two telescopic rods, and the limiting plate is sleeved and slidably installed on the scale rod; a top column is provided at the top end of each of the two telescopic rods, and the two top columns are cylindrical structures with a middle bulge.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By adjusting the lengths of the two telescopic rods, the present invention drives the limiting plate to slide along the scale rod, thereby adjusting the predetermined height of the water level, enabling the device to alarm for water levels at different heights, and thus making the device applicable to rivers with different water levels. When the floating board rises to a certain height following the water level, the floating board pushes the limiting plate upward, causing the limiting plate to push the two telescopic rods and the two top columns upward, triggering the switches of the two alarms to emit an alarm. The two alarms are triggered by the cooperation of the floating board, the two telescopic rods, the two top columns, and the limiting plate. Compared with triggering the two alarms using an induction device, the accident rate is smaller, preventing the induction device from malfunctioning due to the influence of a humid environment, resulting in the inability to convey the water level situation to the management personnel in a timely manner, leading to flood disasters.

[0016] 2. By the impact of water flow on the two groups of hydraulic deflectors, the present invention drives the cross roller to rotate. Under the action of the bevel gear, the cross roller drives the vertical roller and the ten hitting plates to rotate, causing the ten hitting plates to cooperate with the eight sweeping plates to rotate to drive away birds, preventing birds from perching on the device and causing damage to the device. The cover cylinder can prevent birds from contacting the two alarms, causing the birds to trigger the alarms and convey incorrect information to the management personnel. Moreover, when the eight sweeping plates drive the eight groups of cleaning brushes to rotate, the eight groups of cleaning brushes clean the top of the cover cylinder, removing dust and other debris on the top of the cover cylinder.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Please refer to Figures 1 to 8, an embodiment provided by the present invention: a water level alarm device with adjustable height in a water conservancy project, including a scale rod 1. The scale rod 1 includes a support plate 101 and an alarm 102. There is a support plate 101 provided on the top section of the scale rod 1, and two mounting grooves are symmetrically opened on the top of the support plate 101. An alarm 102 is provided in each of these two mounting grooves; a switch is provided at the bottom of each of the two alarms 102; a buried pile 2 is provided at the bottom end of the scale rod 1, and a side groove 3 is opened on each of the left and right sides of the buried pile 2; a support plate is provided at the rear of the top of the buried pile 2, and two rear plates are provided at the rear of the support plate. A cross roller 5 is rotatably installed on these two rear plates; a bevel gear is provided on the middle section of the cross roller 5; a floating plate 4 is sleeved and slidably installed on the scale rod 1, and the floating plate 4 is of a circular structure; a connecting plate 6 is provided at the rear of the support plate 101; a cover cylinder 7 is provided at the top of the scale rod 1, and a plurality of sound emitting grooves are opened on the circumferential outer wall of the cover cylinder 7; the cover cylinder 7 includes a sweeping plate 701 and a cleaning brush 702. Eight sweeping plates 701 are rotatably installed at the top of the cover cylinder 7, and two rows of cleaning brushes 702 are provided at the bottom of each of the eight sweeping plates 701. The cover cylinder 7 can prevent birds from contacting the two alarms 102, causing the birds to trigger the alarms 102 and convey incorrect information to the management personnel. Moreover, when the eight sweeping plates 701 drive the eight groups of cleaning brushes 702 to rotate, the top of the cover cylinder 7 is cleaned by the eight groups of cleaning brushes 702, and dust and other sundries on the top of the cover cylinder 7 are cleaned off; two fixing plates are symmetrically provided at the bottom of the support plate 101. These two fixing plates are of an L-shaped structure, and a telescopic rod 8 is slidably inserted at the inner bottom of each of the two support plates 101.

[0028] The specific brands of the two alarms 102 are: FEDERALDODGE / Federal Dodge; the specific model is: v9.

[0029] Furthermore, the buried pile 2 includes a top plate 201 and a binding plate 202. A top plate 201 is provided at the top of the buried pile 2, and the top plate 201 is of a circular structure; the bottom of the top plate 201 is installed with a binding plate 202 through a spring, and the binding plate 202 is sleeved and slidably installed on the buried pile 2. By the binding plate 202, two soil binding members 302 are blocked, preventing the two soil binding members 302 from popping out when the buried pile 2 is not buried in the river channel, resulting in the need for manual restoration of the two soil binding members 302 to their original positions, which is time-consuming and laborious.

[0030] Furthermore, the side groove 3 includes a connecting plate 301 and soil-piercing members 302. A connecting plate 301 is installed in each of the two side grooves 3 through a spring, and a row of soil-piercing members 302 is provided on the outer side of each of the two connecting plates 301. The two rows of soil-piercing members 302 are of a conical structure. When the buried pile 2 is buried in the river channel, the two connecting plates 301 drive the two groups of soil-piercing members 302 to move outward respectively under the action of the spring, so that the two soil-piercing members 302 penetrate into the soil, thereby making the scale rod 1 stand more stably in the river channel and preventing the scale rod 1 from being washed away by the water flow due to the large impact force of the river.

[0031] Furthermore, the floating plate 4 includes floating balls 401. There are ten connecting blocks provided at the bottom of the floating plate 4, and a floating ball 401 is provided at the bottom of each of the ten connecting blocks. The ten floating balls 401 are of a spherical structure. The floating plate 4 rises and falls with the water level. When the floating plate 4 rises to a certain height, the floating plate 4 pushes the limiting plate 801 upward, so that the limiting plate 801 pushes the two telescopic rods 8 and the two ejector posts 802 upward, triggering the two alarm devices 102. The two alarm devices 102 are triggered through the cooperation of the floating plate 4, the two telescopic rods 8, the two ejector posts 802 and the limiting plate 801. Compared with triggering the two alarm devices 102 using an induction device, the accident rate is smaller, preventing the induction device from malfunctioning due to the influence of a humid environment, resulting in the inability to convey the water level situation to the management personnel in a timely manner. Moreover, the ten floating balls 401 can increase the buoyancy of the floating plate 4.

[0032] Furthermore, the cross roller 5 includes hydraulic deflectors 501 and cutting blades 502. Two groups of hydraulic deflectors 501 are symmetrically provided on the cross roller 5, and a row of cutting blades 502 is provided at the outer end of each hydraulic deflector 501. The two groups of hydraulic deflectors 501 are impacted by the water flow, driving the cross roller 5 to rotate. The cross roller 5 drives the vertical roller 601, the ten striking plates 602 and the eight sweeping plates 701 to rotate under the action of bevel gears, thereby providing power for the eight sweeping plates 701 using the impact force of the water flow, saving the electric power resources wasted by using transmission equipment, and preventing debris in the water flow from winding around the cross roller 5 and the two groups of hydraulic deflectors 501 through the two groups of cutting blades 502.

[0033] Furthermore, the connecting plate 6 includes a vertical roller 601 and striking plates 602. A vertical roller 601 is rotatably installed at the rear end of the top of the connecting plate 6, and a bevel gear is provided at the bottom end of the vertical roller 601, and this bevel gear meshes with the bevel gear on the cross roller 5; ten striking plates 602 are provided at the top of the vertical roller 601. The cross roller 5 drives the vertical roller 601 and the ten striking plates 602 to rotate under the action of bevel gears, causing the ten striking plates 602 to cooperate with the eight sweeping plates 701 to rotate to drive away birds, preventing birds from perching on the device and causing damage to the device.

[0034] Further, the telescopic rod 8 includes a limit plate 801 and a top column 802. A limit plate 801 is provided at the bottom end of the two telescopic rods 8, and the limit plate 801 is sleeved and installed on the scale rod 1; a top column 802 is provided at the top end of the two telescopic rods 8, and the two top columns 802 are cylindrical structures with a middle bulge. By adjusting the lengths of the two telescopic rods 8, the limit plate 801 is driven to slide along the scale rod 1, so as to adjust the predetermined height of the water level, enabling the device to alarm the water levels of different heights, and further enabling the device to be applicable to rivers with different water levels.

[0035] Working principle: During use, first bury the pile 2 in the river, then slide the beam plate 202 upward so that it no longer resists the two soil-piercing members 302. Then, under the action of the spring, the two connecting plates 301 drive the two soil-piercing members 302 to move outward respectively, so that the two soil-piercing members 302 penetrate into the soil, making the scale rod 1 stand more stably in the river and preventing the scale rod 1 from being washed away by the water flow due to the large impact force of the river. Then, by adjusting the lengths of the two telescopic rods 8, the limit plate 801 is driven to slide along the scale rod 1, so as to adjust the predetermined height of the water level, enabling the device to alarm the water levels of different heights. Thus, the installation and adjustment steps are completed; when the water flow impacts the two hydraulic deflector plates 501, the two hydraulic deflector plates 501 drive the cross roller 5 to rotate. The cross roller 5 drives the vertical roller 601 and ten striking plates 602 to rotate under the action of the bevel gear, so as to drive the eight sweeping plates 701 to rotate, enabling the ten striking plates 602 and the eight sweeping plates 701 to cooperate and rotate to drive away birds, preventing birds from perching on the device and causing damage to the device. Moreover, when the eight sweeping plates 701 drive the eight cleaning brushes 702 to rotate, the top of the cover cylinder 7 is cleaned by the eight cleaning brushes 702, removing dust and other sundries on the top of the cover cylinder 7. When the floating plate 4 rises to a certain height following the water level, the floating plate 4 pushes the limit plate 801 upward, causing the limit plate 801 to push the two telescopic rods 8 and the two top columns 802 upward, triggering the switches of the two alarms 102 to emit an alarm, thereby promptly conveying the water level situation to the management personnel and preventing flood disasters.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
