Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a rainstorm and flood early warning device. Background Technology

[0002] The rainstorm and flood warning device is used to collect rainfall, rainfall intensity, and rainfall duration in real time to determine whether the rainstorm or extreme rainstorm standard has been reached, and to track whether the water level is approaching the warning level.

[0003] In the prior art, a rainstorm and flood early warning device with patent publication number CN220933595U includes: a fixing mechanism, including a fixing base, an installation port through which the fixing base is formed, multiple drainage channels through which the lower part of the inner wall of the installation port is formed, a support plate connected to the inner wall of the installation port, a first fixing half ring vertically connected to one side of the installation port, and a second fixing half ring correspondingly provided on the other side; and an early warning mechanism, detachably installed in the installation port, including an early warning cylinder.

[0004] Although the device can prevent the warning cylinder from being blown over or washed away by rain when it is subjected to strong winds by fixing nails, in actual use, if the ground softens due to heavy rain, the anchoring force of the fixing nails will decrease significantly, further increasing the risk of the device shaking. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rainstorm and flood early warning device, which can effectively solve the problem that if the ground softens due to rainstorms, the anchoring force of the fixing nail will decrease significantly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a rainstorm and flood early warning device, including a fixed plate, a mounting frame fixedly installed on the outer surface of the fixed plate, an early warning cylinder disposed on the inner side of the mounting frame, and a protective cap fixedly connected to the top of the early warning cylinder;

[0008] The support mechanism includes a force-bearing component for generating downward pressure during rainfall, a transmission component for converting the downward pressure of the force-bearing component into upward pressure, an expansion component that can expand in the soil with the upward pressure of the transmission component, and an auxiliary component for preventing the expansion component from expanding during insertion into the soil.

[0009] The support mechanism is located at the four corners of the fixing plate, and the expansion assembly is used to insert into the soil to ensure the stability of the fixing plate.

[0010] The force-bearing component includes a fixed plate fixedly connected to the top of the fixed plate, a fixed cylinder fixedly installed on the top of the fixed plate, a movable block slidably connected to the inner wall of the fixed cylinder, and a water storage tank fixedly installed on the outer end face of the movable block for collecting rainwater.

[0011] Furthermore, the force-bearing component also includes a pressure-applying inclined block integrally formed on the inner wall of the movable block, and a drain plug inserted into the bottom of the water storage tank for controlling rainwater discharge.

[0012] Furthermore, the transmission assembly includes a fixed column fixedly connected to the top of the fixed plate, a movable column slidably connected to the inner surface of the fixed column, a diagonal brace slidably connected to the inner surface of the movable column and used in conjunction with the pressure-applying inclined block, a sliding groove penetrating the surface of the fixed column and used in conjunction with the diagonal brace, and a spring fixedly installed on the top of the movable column.

[0013] Furthermore, the fixed column is located inside the fixed cylinder, the outer surface of the pressure-applying inclined block slides in contact with the outer end face of the inclined support rod, the inclined support rod is slidably connected to the inner wall of the slide groove, and the outer end face of the spring abuts against the inner wall of the movable block; when water accumulates inside the water tank, the movable block and the pressure-applying inclined block can be moved downward by the gravity of the rainwater, and then the pressure-applying inclined block squeezes the inclined support rod, causing the inclined support rod to slide along the inner wall of the slide groove, while the outer contour drives the movable column to move upward along the fixed column and squeeze the spring.

[0014] Furthermore, the expansion assembly includes a connecting column fixedly installed at the through end of the movable column, a cone head integrally formed at the other end of the connecting column for insertion into the soil, a plurality of single-sided inclined blocks arranged in a circumferential array on the outer surface of the connecting column, an inclined slider slidably sleeved on the outer surface of the single-sided inclined block, an opening and closing plate fixedly connected to the other side of the inclined slider, and a limiting block fixedly connected to the outer end face of the opening and closing plate.

[0015] Furthermore, the limiting block is slidably connected to the bottom of the fixed disk; when the movable column moves upward, it can drive multiple single-sided inclined blocks to move upward synchronously through the connecting column, and then the multiple single-sided inclined blocks simultaneously squeeze the corresponding inclined sliders, thereby causing the multiple inclined sliders to simultaneously drive the corresponding opening and closing plates and limiting blocks to slide and unfold along the bottom of the fixed disk, thereby increasing the contact area with the soil.

[0016] Furthermore, the auxiliary component includes an internally threaded block fixedly connected to the outer surface of the fixed disk, a threaded rod threadedly connected to the inner surface of the internally threaded block, and a positioning hole opened on the outer surface of the movable column and used in conjunction with the threaded rod.

[0017] Furthermore, when the threaded rod is screwed into the positioning hole, it can limit the movement of the movable column, thereby preventing the connecting column and the movable column from moving upwards by the reaction force during the process of the cone head being inserted into the soil.

[0018] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0019] By setting up a support mechanism, this utility model can not only automatically drive multiple opening and closing plates to unfold in the soil and form radial support when the ground softens due to heavy rain, greatly increasing the contact area and engagement depth with the soil, but also prevent multiple opening and closing plates from unfolding accidentally during the installation of the support mechanism. This ensures the stability of the early warning device body in heavy rain conditions while ensuring the accuracy of the early warning function. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example: A rainstorm and flood early warning device, as shown in the attached document. Figure 1 -Appendix Figure 6 ,include,

[0031] The fixture 110, the mounting bracket 120 fixedly installed on the outer surface of the fixture 110, the warning tube 130 disposed inside the mounting bracket 120, and the protective cap 140 fixedly connected to the top of the warning tube 130;

[0032] It should be noted that the fixing plate 110 is used to fix the warning tube 130 through the mounting bracket 120. The mounting bracket 120 is used to provide lateral support for the warning tube 130 to prevent it from shaking under direct force. The warning tube 130 has built-in flood monitoring elements, such as water level sensing and related structures, which are the core functional components for realizing rainstorm and flood warning. The warning tube 130 is existing technology, and this solution will not describe it in detail. Moreover, those skilled in the art can clearly understand its working principle. The protective cap 140 blocks and prevents rainwater and debris from entering the interior of the warning tube 130, protecting the monitoring elements from damage.

[0033] The support mechanism 200 includes a force-receiving component 210 for generating downward pressure during rainfall, a transmission component 220 for converting the downward pressure of the force-receiving component 210 into upward pressure, an expansion component 230 that can expand in the soil with the upward pressure of the transmission component 220, and an auxiliary component 240 for preventing the expansion component 230 from expanding during the process of being inserted into the soil.

[0034] The support mechanism 200 is located at the four corners of the fixing plate 110, and the expansion component 230 is used to insert into the soil to ensure the stability of the fixing plate 110.

[0035] The force-bearing component 210 includes a fixed plate 211 fixedly connected to the top of the fixed plate 110, a fixed cylinder 212 fixedly installed on the top of the fixed plate 211, a movable block 213 slidably connected to the inner wall of the fixed cylinder 212, and a water storage tank 214 fixedly installed on the outer end face of the movable block 213 for collecting rainwater.

[0036] Specifically, the force-bearing component 210 also includes a pressure-applying inclined block 215 integrally formed on the inner wall of the movable block 213, and a drain plug 216 inserted into the bottom of the water storage tank 214 for controlling rainwater discharge.

[0037] It should be noted that the water storage tank 214 is used to automatically store water during rainfall, and its weight can increase with the amount of water accumulated. The drain plug 216 can be pulled out after the rainfall ends to drain the water accumulated in the water storage tank 214.

[0038] Furthermore, the transmission assembly 220 includes a fixed column 221 fixedly connected to the top of the fixed plate 211, a movable column 222 slidably connected to the inner surface of the fixed column 221, a diagonal brace 223 slidably connected to the inner surface of the movable column 222 and used in conjunction with the pressure-applying inclined block 215, a slide groove 224 penetrating the surface of the fixed column 221 and used in conjunction with the diagonal brace 223, and a spring 225 fixedly installed on the top of the movable column 222.

[0039] It should also be noted that the downward-moving pressure block 215 can squeeze the inclined support rod 223 through the inclined surface, causing the inclined support rod 223 to slide horizontally along the slide groove 224. When the inclined support rod 223 slides, it can generate an upward thrust on the movable column 222 through its outer contour, causing the movable column 222 to move upward along the inner wall of the fixed column 221 and squeeze the spring 225 at the top. The spring 225 is used to store elastic potential energy for subsequent reset.

[0040] Preferably, the fixed column 221 is located inside the fixed cylinder 212, the outer surface of the pressure block 215 slides in contact with the outer end face of the diagonal support rod 223, the diagonal support rod 223 is slidably connected to the inner wall of the slide groove 224, and the outer end face of the spring 225 abuts against the inner wall of the movable block 213. When water accumulates inside the water tank 214, the movable block 213 and the pressure block 215 can be moved down by the gravity of the rainwater, and then the pressure block 215 squeezes the diagonal support rod 223, so that the diagonal support rod 223 slides along the inner wall of the slide groove 224, while the movable column 222 is driven up along the fixed column 221 by the outline of the column, and the spring 225 is squeezed.

[0041] It should be noted that the expansion assembly 230 includes a connecting column 231 fixedly installed at the through end of the movable column 222, a cone head 232 integrally formed at the other end of the connecting column 231 for insertion into the soil, a plurality of single-sided inclined blocks 233 distributed in a circumferential array on the outer surface of the connecting column 231, an inclined slider 234 slidably sleeved on the outer surface of the single-sided inclined block 233, an opening and closing plate 235 fixedly connected to the other side of the inclined slider 234, and a limiting block 236 fixedly connected to the outer end face of the opening and closing plate 235.

[0042] Furthermore, the upward-moving movable column 222 can drive the connecting column 231 to move upward synchronously, thereby causing the connecting column 231 to drive multiple single-sided inclined blocks 233 to move upward with the connecting column 231. The inclined surfaces of the single-sided inclined blocks 233 generate radial thrust that pushes outward on the slider 234, which in turn causes the inclined slider 234 to drive the opening and closing plate 235 and the limiting block 236 to slide along the bottom of the fixed plate 211 and unfold outward. The unfolded multiple opening and closing plates 235 can form a radial support structure, thereby greatly increasing the contact area and interlocking depth with the soil. Even if the ground softens due to heavy rain, it can still achieve strong anchoring through friction and mechanical interlocking to ensure the stability of the fixed plate 110.

[0043] Furthermore, the limiting block 236 is slidably connected to the bottom of the fixed plate 211; when the movable column 222 moves upward, it can drive multiple single-sided inclined blocks 233 to move upward synchronously through the connecting column 231, and then the multiple single-sided inclined blocks 233 simultaneously squeeze the corresponding inclined sliders 234, thereby causing the multiple inclined sliders 234 to simultaneously drive the corresponding opening and closing plates 235 and the limiting block 236 to slide and unfold along the bottom of the fixed plate 211, thereby increasing the contact area with the soil.

[0044] Specifically, the auxiliary component 240 includes an internally threaded block 241 fixedly connected to the outer surface of the fixed disk 211, a threaded rod 242 threadedly connected to the inner surface of the internally threaded block 241, and a positioning hole 243 opened on the outer surface of the movable column 222 and used in conjunction with the threaded rod 242.

[0045] Preferably, when the threaded rod 242 is screwed into the positioning hole 243, it can limit the movable column 222, thereby preventing the connecting column 231 and the movable column 222 from moving upward through the reaction force during the process of the cone head 232 being inserted into the soil.

[0046] The threaded rod 242 axially limits the movable column 222 through the positioning hole 243, which can prevent the reaction force of the cone head 232 when it is inserted into the soil from driving the connecting column 231 and the movable column 222 to move upward, prevent the expansion component 230 from unfolding prematurely, and ensure smooth installation.

[0047] When using,

[0048] Place the fixed plate 110 in the designated position, then rotate the threaded rod 242 so that it is screwed into the positioning hole 243, forming an axial limit on the movable column 222. Then insert the cone 232 into the soil. During this process, the limiting effect of the threaded rod 242 prevents the reaction force from driving the connecting column 231 and the movable column 222 to move upward, thus preventing the expansion component 230 from unfolding prematurely.

[0049] Then, the warning cylinder 130 is fixed to the top of the fixing plate 110 by the mounting bracket 120, and the top of the warning cylinder 130 is covered by the protective cap 140 to protect the internal components. After installation, the threaded rod 242 is unscrewed to put the device into standby mode.

[0050] When rainfall occurs: rainwater is collected by the water storage tank 214. The weight of the water storage tank 214 increases with the increase of water accumulation. The gravity of the rainwater drives the movable block 213 and the pressure inclined block 215 to move down synchronously along the inner wall of the fixed cylinder 212. Then, the pressure inclined block 215 squeezes the inclined support rod 223, causing it to slide horizontally along the inner wall of the slide groove 224. At the same time, the inclined support rod 223 drives the movable column 222 to move up along the inner wall of the fixed column 221 through its outer contour, and squeezes the spring 225.

[0051] At the same time, the movable column 222 drives the connecting column 231 and the single-sided inclined block 233 to move upward synchronously. The single-sided inclined block 233 pushes the opening and closing plate 235 to drive the limiting block 236 to unfold along the bottom of the fixed plate 211 by squeezing the inclined slider 234, and forms a radial support, thereby increasing the contact area with the soil and greatly improving the support effect on the early warning device body 100.

[0052] After the rainfall ends: Pull out the drain plug 216 to empty the water tank 214. The reaction force of the spring 225 pushes the movable column 222 and the movable block 213 to reset, so that the opening and closing plate 235 can be retracted, so that the support mechanism 200 can be pulled out of the soil.

[0053] In summary, by setting up the support mechanism 200, not only can multiple opening and closing plates 235 be automatically driven to unfold in the soil and form radial support when the ground softens due to heavy rain, greatly increasing the contact area and engagement depth with the soil, but also the multiple opening and closing plates 235 can be prevented from unfolding accidentally during the installation of the support mechanism 200. This ensures the stability of the warning device body 100 in heavy rain conditions while ensuring the accuracy of the warning function.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
