Description

Technical Field

[0001] This invention relates to the field of dam liquid level safety technology, and in particular to a dam liquid level safety alarm device. Background Technology

[0002] To develop and utilize river hydropower resources, dams can be built across the river. The construction of dams requires controlling and directing the water flow, while also placing them in appropriate locations to coordinate with the implementation of water conservancy and hydropower tasks. The resulting dam system can become an organic whole, enabling the effective utilization of water resources.

[0003] Changes in dam water levels have a significant impact on people's lives. During heavy rains that cause water levels to rise, visibility is easily obstructed, making it difficult for staff to clearly observe water level monitoring devices. Therefore, different alarm methods are needed when water levels reach warning and danger levels to promptly alert staff for appropriate action. To achieve this, the monitoring devices need to adjust the warning position according to different water levels. When the water level reaches a point prone to flooding, a rapid alarm must be triggered to prevent flooding accidents. Summary of the Invention

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0040] Reference Figures 1-7 This is one embodiment of the present invention, which provides a dam liquid level safety alarm device, including a mounting base 100, a monitoring unit 200 slidably connected to the mounting base 100, a warning unit 300 and an alarm unit 400 driven by the monitoring unit 200, and a locking unit 500 driven by the warning unit 300.

[0041] The locking unit 500 is used to lock the alarm unit 400.

[0042] Furthermore, the monitoring unit 200 includes a drive assembly 201 driven by water level rise and fall, a scale plate 202 driven by the drive assembly 201 to rise and fall, multiple range plates 203 disposed on one side surface of the scale plate 202, and a prompting assembly 204 driven by the drive assembly 201. The scale plate 202 and the mounting base 100 are provided with matching protrusions and vertical grooves, so that the scale plate 202 can only rise and fall vertically along the mounting base 100.

[0043] The drive assembly 201 includes a float 201a that contacts the water surface, and a drive rod 201b that is driven to rise and fall by the float 201a.

[0044] The scale plate 202 is driven by the drive rod 201b to move vertically up and down along the mounting base 100.

[0045] Furthermore, the prompting component 204 is provided in multiple sets, and each prompting component 204 corresponds to a range plate 203;

[0046] The prompting component 204 includes a first opening 204a disposed on the side wall of the scale plate 202, a first fixing block 204b fixedly disposed in the first opening 204a, a first power-conducting block 204c fixedly connected to the first fixing block 204b, a light-emitting element 204d electrically connected to the first power-conducting block 204c, a first trapezoidal block 204e fixedly connected to the upper surface of the mounting base 100, and a pressing element 204f that moves horizontally driven by the first trapezoidal block 204e. The light-emitting element 204d can emit light using existing technology and is set to emit green (corresponding to normal water level height), orange (corresponding to warning water level height), and red (corresponding to alarm water level height) light according to the height of the range plate 203 to illuminate the range plate 203 and facilitate observation of the height of the range plate 203 in inclement weather.

[0047] The light-emitting element 204d is fixedly mounted on the surface of the scale plate 202.

[0048] It should be noted that during the process of the scale plate 202 being vertically raised and lowered along the mounting base 100 by the drive rod 201b,

[0049] The pressing member 204f contacts the first trapezoidal block 204e, causing the pressing member 204f to move horizontally along the first opening 204a. Before moving, the pressing member 204f does not contact the first energized block 204c, and the light-emitting member 204d does not emit light. That is, when the driving rod 201b is driven by the buoyancy of the float 201a to move the scale plate 202 to a corresponding height, the corresponding range plate 203 rises to the surface of the mounting base 100 during the movement. At the same time, the pressing member 204f is pressed by the first trapezoidal block 204e and moves horizontally along the first opening 204a, causing the light-emitting member 204d corresponding to the current range plate 203 to emit light.

[0050] Preferably, the light-emitting element 204d can not only illuminate the corresponding measuring plate 203, but also allow the staff to roughly understand the water level corresponding to the current water level height through the emitted light.

[0051] Furthermore, the pressing component 204f includes a second trapezoidal block 204f-1, a first horizontal rod 204f-2 fixedly connected to one side of the second trapezoidal block 204f-1, a first horizontal plate 204f-3 fixedly sleeved on the first horizontal rod 204f-2, a second energized block 204f-4 fixedly connected to one end of the first horizontal rod 204f-2, and a first spring 204f-5 connecting the first fixing block 204b and the first horizontal plate 204f-3;

[0052] The first horizontal plate 204f-3 can move horizontally along the first opening 204a.

[0053] It should be noted that as the water level rises to a certain height, the scale plate 202 rises vertically along the mounting base 100, causing the second trapezoidal block 204f-1 to be squeezed by the first trapezoidal block 204e during the rise, which in turn causes the first horizontal plate 204f-3 and the first horizontal rod 204f-2 to move horizontally along the first opening 204a. During the movement, the first spring 204f-5 is compressed, and the first energized block 204c and the second energized block 204f-4 come into contact, thereby supplying power to the light-emitting element 204d corresponding to the current water level, and the light-emitting element 204d emits light.

[0054] Furthermore, the warning unit 300 includes a driven block 301 fixedly connected to one side of the scale plate 202, a first slot 302 disposed in the driven block 301, a moving block 303 engaged with the driven block 301 through the first slot 302, a second fixed block 308 and a third fixed block 304 fixedly connected to the mounting base 100, a first fixed post 305 fixedly connected to the second fixed block 308, a horizontal member 306 slidably connected to the third fixed block 304, and a warning member 307 that is driven to rise and fall by the horizontal member 306, wherein the moving block 303 is provided with two inclined surfaces;

[0055] The horizontal component 306 is driven to move horizontally by the moving block 303. The second fixed block 308 and the third fixed block 304 are arranged in parallel. When the horizontal component 306 moves horizontally, the current water level corresponds to the warning water level, and the orange light of the light-emitting component 204d is activated.

[0056] Furthermore, the horizontal member 306 includes a second horizontal rod 306a driven by the driven block 301, a second horizontal plate 306b fixedly sleeved on the second horizontal rod 306a, a second spring 306c connecting the third fixed block 304 and the second horizontal plate 306b, and a first inclined block 306d fixedly connected to one end of the second horizontal rod 306a.

[0057] The second horizontal bar 306a is movably connected to the third fixed block 304;

[0058] It should be noted that during the lifting and lowering process of the scale plate 202, the driven block 301 is moved synchronously. The driven plate moves the moving block 303. During the movement, one inclined surface of the moving block 303 is pressed by the first fixed column 305 and moves horizontally along the first slot 302. It is also pressed by the second horizontal bar 306a through the other inclined surface. The second horizontal plate 306b and the first inclined block 306d move horizontally along the third fixed block 304 in sync.

[0059] The warning component 307 includes a shaped block 307a that is driven to rise and fall by a first inclined block 306d, and a warning sign 307b that is fixedly connected to the upper surface of the shaped block 307a. The warning sign 307b is movably inserted through the mounting base 100. The side wall of the shaped block 307a is provided with a protrusion that is adapted to the mounting base 100, so that the warning sign 307b can only move vertically along the mounting base 100.

[0060] The irregular block 307a includes a second inclined block 307a-1 and a third inclined block 307a-2, as well as a vertical connecting block 307a-3 connecting the second inclined block 307a-1 and the third inclined block 307a-2.

[0061] It should be noted that when the warning sign 307b is not at the warning water level, it is located inside the mounting base 100 and rises and falls with the rise and fall of the warning water level. When the water level is higher than the first time, causing the second horizontal bar 306a to move to the maximum displacement, the vertical section of the moving block 303 can keep the second horizontal bar 306a stationary. That is, only when the water level is lower than the maximum displacement, the first inclined block 306d moves horizontally to reset under the reset action of the second spring 306c.

[0062] Furthermore, the locking unit 500 includes a fourth inclined block 501 that moves horizontally via the third inclined block 307a-2, a third horizontal rod 502 with one end fixedly connected to the fourth inclined block 501, a third horizontal plate 503 fixedly sleeved on the third horizontal rod 502, an opening frame 505 fixedly connected to the inner wall of the mounting base 100, a third spring 506 connecting the third horizontal plate 503 and the opening frame 505, and a clamping member 507 driven by the third horizontal plate 503.

[0063] Furthermore, the clamping member 507 includes a third trapezoidal block 507a fixedly connected to the other end of the third horizontal bar 502, two inclined protrusions 507b fixedly connected to the two side walls of the third trapezoidal block 507a, two fifth inclined blocks 507c driven by the two inclined protrusions 507b, and a clamping arc block 507d fixedly connected to the side walls of the two fifth inclined blocks 507c.

[0064] The two fifth inclined blocks 507c move vertically along the opening frame 505.

[0065] It should be noted that during the movement of the irregular block 307a, the third inclined block 307a-2 drives the fourth inclined block 501 to move horizontally, and simultaneously drives the third horizontal rod 502 to move horizontally along the opening frame 505. The third horizontal rod 502 drives the two fifth inclined blocks 507c to move vertically along the opening frame 505, moving closer or further apart from each other, through the third trapezoidal block 507a. The alarm unit 400 is locked by the two clamping arc blocks 507d.

[0066] Furthermore, the alarm unit 400 includes a vertical rack 401 fixedly connected to the side wall of the scale plate 202, a first rotating shaft 402 and a second rotating shaft 403 rotatably connected to the mounting base 100, a gear 404 fixedly sleeved on the first rotating shaft 402, a transmission belt 405 connecting the first rotating shaft 402 and the second rotating shaft 403, a mounting plate 406 fixedly connected to the inner wall of the mounting base 100, two L-shaped plates 407 fixedly connected to the mounting plate 406, a third power-conducting post 408 fixedly connected to the two L-shaped plates 407, and a driven alarm element 409 driven by the second rotating shaft 403.

[0067] The vertical rack 401 can drive the gear 404 to rotate, and the second rotating shaft 403 is rotatably connected to the mounting plate 406.

[0068] It should be noted that when the vertical rack 401 is triggered to drive the gear 404 to rotate, the current water level is lower than the alarm water level, and the corresponding light-emitting element 204d turns orange. When the driven alarm element 409 issues an alarm, the alarm water level is reached, and the corresponding light-emitting element 204d turns red.

[0069] Furthermore, the driven alarm component 409 includes a first arc block 409a, a first connecting rod 409b and a second connecting rod 409c fixedly connected to the second rotating shaft 403; a first arc-shaped rack 409d fixedly connected to the first arc block 409a; a third rotating shaft 409e rotatably connected to the mounting plate 406; a second arc block 409f fixedly connected to the third rotating shaft 409e; a third connecting rod 409g and a fourth connecting rod 409h; a second arc-shaped rack 409i fixedly connected to the second arc block 409f; a fifth connecting rod 409j connected at one end to the first connecting rod 409b; a sixth connecting rod 409k connected at one end to the third connecting rod 409g; and a lifting platform 4 connected to both the fifth connecting rod 409j and the sixth connecting rod 409k. 09l, a fourth rotating shaft 409m and a fifth rotating shaft 409n rotatably connected to the mounting plate 406, a seventh connecting rod 409o rotatably connected to the fourth rotating shaft 409m at one end, an eighth connecting rod 409p rotatably connected to the fifth rotating shaft 409n at one end, a first protective plate 409r connected to the other end of the seventh connecting rod 409o, a second protective plate 409s connected to the other end of the eighth connecting rod 409p, and an alarm 409t fixedly connected to the upper surface of the lifting platform 409l, wherein the other end of the first connecting rod 409b is connected to the first protective plate 409r, the other end of the third connecting rod 409g is connected to the second protective plate 409s, and the two side walls of the lifting platform 409l are provided with fourth power blocks;

[0070] The first arc-shaped rack 409d and the second arc-shaped rack 409i are engaged and connected.

[0071] It should be noted that before the alarm water level is reached, the lifting block is at its lowest point. When the alarm water level is reached, the lifting block is at its highest point. When the lifting block rises to its highest point, the third power column 408 connects with the fourth power block to supply power to the alarm 409t and trigger the alarm.

[0072] Preferably, by clamping the second rotating shaft 403 with the locking unit 500, the first protective plate 409r and the second protective plate 409s can be brought into contact, thereby protecting the alarm 409t (reducing false alarms caused by birds accidentally triggering the alarm 409t to rise). When the warning water level is reached, the driven alarm 409t is unlocked at the same time as the warning sign 307b is raised, so that the alarm 409t can sound the alarm immediately when the alarm water level is reached.

[0073] In use, this invention includes three processes:

[0074] In the first usage process, at the normal water level, the light-emitting element 204d emits green light. Specifically, the buoyancy of the float 201a drives the drive rod 201b to rise and fall. The drive rod 201b drives the scale plate 202 to rise and fall vertically along the mounting base 100. During the rising and falling process, the second trapezoidal block 204f-1 corresponding to the current water level is squeezed by the first trapezoidal block 204e, which drives the first horizontal plate 204f-3 and the first horizontal rod 204f-2 to move horizontally along the first opening 204a. During the movement, the first spring 204f-5 is compressed, and the first energized block 204c and the second energized block 204f-4 come into contact, thereby supplying power to the light-emitting element 204d corresponding to the current water level, and the light-emitting element 204d emits green light.

[0075] In the second usage process, when the water level is high, the luminous element 204d emits orange light, and the warning sign 307b rises. Specifically, during the lifting and lowering movement of the scale plate 202, the driven block 301 moves synchronously. The driven plate moves the moving block 303. During the movement, one inclined surface of the moving block 303 is pressed by the first fixed column 305 and moves horizontally along the first slot 302. It also presses the second horizontal bar 306a through another inclined surface. The second horizontal plate 306b and the first inclined block 306d move horizontally along the third fixed block 304, thereby raising and lowering the warning sign 307b. The luminous element 204d emits orange light.

[0076] In the third usage process, when the alarm water level is reached, the luminous element 204d emits a red light, and the alarm 409t sounds. Specifically, before the alarm water level is reached (meaning after the warning water level is reached), the rise of the irregular block 307a causes the warning sign 307b to rise. Further, the third inclined block 307a-2 drives the fourth inclined block 501 to move horizontally, simultaneously driving the third horizontal rod 502 and the third horizontal rod 502 to move horizontally along the opening frame 505. The third spring 506 is compressed, and the third horizontal rod 502, through the third trapezoidal block 507a, drives the two fifth inclined blocks 507c to move vertically away from each other along the opening frame 505, releasing the locking effect of the two clamping arc blocks 507d on the alarm unit 400. When the vertical rack 401 drives the gear 404 to rotate, the gear 404 rotates, causing the first rotating shaft 402 to rotate. The first rotating shaft 402, through the transmission belt 405, carries... The second rotating shaft 403 rotates, and further, the second rotating shaft 403 synchronously drives the first arc block 409a, the first connecting rod 409b, and the second connecting rod 409c to rotate. The first arc block 409a drives the second arc rack 409i to rotate through the first arc rack 409d, which in turn drives the second arc block 409f, the third connecting rod 409g, and the fourth connecting rod 409h to rotate, which in turn drives the fifth connecting rod 409j and the sixth connecting rod 409k to move, thereby raising the lifting platform 409l. At the same time, the first protection plate 409r is moved by the first connecting rod 409b and the seventh connecting rod 409o, and the second protection plate 409s is moved by the third connecting rod 409g and the eighth connecting rod 409p. The two protection plates move away from each other. When the alarm water level is reached, the third energizing column 408 is connected to the fourth energizing column of the lifting platform 409l, triggering the alarm 409t, and the luminous element 204d emits red light.

[0077] In summary, the beneficial effects of the dam liquid level safety alarm device of the present invention are that it can trigger a warning or alarm mode corresponding to the current water level according to different water level heights, which makes it convenient for staff to take corresponding measures according to different alarm modes, and timely prevent the water level from rising, thus facilitating flood prevention. On the other hand, the setting of the protection plate and the locking unit 500 can protect the alarm 409t to a certain extent and reduce the false alarm caused by birds accidentally triggering the alarm 409t to rise, thereby improving the alarm accuracy of the device.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
