Description

Technical Field

[0001] This utility model relates to the field of flood control and early warning technology for water conservancy projects, and more specifically, to a flood control and early warning device for water conservancy reservoirs. Background Technology

[0002] A reservoir is a water storage site formed by constructing dams, dikes, or intercepting walls in places with water sources or through other waterways, such as rivers, valleys, low-lying areas, or permeable underground layers. Flood prevention and early warning refers to the systematic work carried out in flood forecasting, flood control scheduling, and the operation of flood control projects to prevent and mitigate flood disasters. Its core objective is to reduce the threat of floods to people's lives and property through scientific monitoring and rapid response. A water gauge is a measuring tool for reservoir flood prevention and early warning. Its core function is to display the water level in real time through scale markings, providing basic data support for flood prevention and early warning.

[0003] The shortcomings of existing technologies: In existing flood warning methods, water gauges are installed on the bank where water levels are measured for flood warning operations. However, the size of the water gauges is fixed and cannot be extended or retracted. During the dry season, the lowest measuring point of the fixed water gauge is higher than the actual water level, causing the water level to fall below the lower limit of the measuring range and making it impossible to record data. During the flood season, the highest measuring point of the fixed water gauge is lower than the actual water level, causing the water level to exceed the upper limit of the measuring range and making it impossible to record the highest water level. This increases the reading error and creates the limitation of the fixed measuring range, which is not conducive to practical application and operation. Utility Model Content

[0014] The following will be combined with the appendix Figures 1 to 7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 4 This utility model embodiment provides a flood control early warning device for water conservancy reservoirs, including: Support rod 1 is connected to crossbar 2 via folding assembly 3; The flood warning component 4 is connected to the crossbar 2 via the disassembly component 5 and serves as the installation carrier for the enclosure component 6 and the protection component 7, and is used for early warning measurement of water level. Flood warning component 4 includes: Outer diameter tube 41; The inner ruler rod 42 is slidably fitted inside the outer ruler cylinder 41; The receiving plate 43 is installed on the outer side of the top of the outer scale tube 41; The slide groove 44 is formed on the outside of the outer cylinder 41, and the slide groove 44 is located below the receiving plate 43; The lead screw 45 is rotatably fitted inside the slide groove 44; Slider 46 and lead screw 45 form a helical pair transmission, and one side of slider 46 is fixedly connected to the outer side of the top end of inner ruler rod 42. Magnetic patches are provided at both ends of the outer scale tube 41; The limiting plate 49 has a magnet on its inner side that is attracted to a magnetic patch on the outer side of the outer scale tube 41, and the limiting plate 49 is located below the receiving plate 43. Pressure sensors 410 are installed on both sides of the bottom of the limiting plate 49; The float plate 411 is fitted onto the outside of the outer ruler cylinder 41 and the inner ruler rod 42; Alarm 412 is installed at the top of support rod 1; Motor 47 is mounted on top of receiving plate 43; The pulleys 48 are respectively installed on the outer side of the top of the lead screw 45 and the output shaft of the motor 47, and the two pulleys 48 are connected by a synchronous belt drive.

[0016] In practical application, during flood season, the limiting plate 49 is located outside the top of the outer ruler cylinder 41, with the bottom of the outer ruler cylinder 41 inserted into the water. This causes the float 411, fitted onto the outside of the outer ruler cylinder 41, to rise with the water level. When the float 411 contacts the pressure sensor 410 at the bottom of the limiting plate 49, the pressure sensor 410 reading changes, triggering the alarm 412 to sound. During dry season, the limiting plate 49 is moved and mounted on the magnetic patch on the bottom of the outer ruler cylinder 41 using a magnet. Simultaneously, the motor 47 on the receiving plate 43 drives one of the pulleys 48 to rotate, and in conjunction with a synchronous belt, drives the other pulley 48 to rotate. The rotation causes the lead screw 45 in the slide groove 44 to rotate, which in turn causes the slider 46 on the lead screw 45 to slide downward in the slide groove 44. At the same time, the inner ruler rod 42 in the outer ruler cylinder 41 slides downward synchronously, so that the float plate 411 is sleeved on the outside of the outer ruler cylinder 41 and the inner ruler rod 42 and floats on the water surface. When the water level gradually rises, the float plate 411 rises synchronously. When the float plate 411 comes into contact with the pressure sensor 410 at the bottom of the limit plate 49, the value of the pressure sensor 410 changes, which in turn causes the alarm 412 to sound. This is convenient for water level monitoring during flood season and dry season, and further facilitates real-time monitoring and early warning of water levels at different heights.

[0017] This embodiment, by setting up a flood warning component 4, facilitates real-time monitoring of water levels during flood or dry seasons. It further facilitates real-time monitoring and early warning of water levels at different heights, solving the problem that traditional measuring tools, due to their fixed length, cannot adjust the length of the water gauge. It also solves the problem that the inability to adjust the length of the measuring tool makes it unsuitable for measuring water levels at different times, resulting in the inability to record the highest or lowest water level. This reduces reading errors, improves the practicality of the equipment, and is beneficial for practical application and operation.

[0018] In one embodiment, the surface of the lead screw 45 can be treated with processes such as galvanizing, chrome plating, and spraying anti-rust paint to form a protective layer, preventing moisture and oxygen from directly contacting the metal surface; the pressure sensor 410 is an integrated pressure sensor, model MPX series-MPX5050. The drive association between the pressure sensor 410 and the alarm 412 is existing technology, which can be fully implemented by those skilled in the art without further explanation.

[0019] Please see Figure 1 and 3 In a preferred embodiment of this utility model, the folding component 3 includes: Storage slot 31 is installed on the outside of support rod 1; The crossbar 2 is rotatably fitted inside the storage slot 31; Connecting plate 32 is installed on the outer side of one end of crossbar 2; Insert rod 33 is slidably fitted inside connecting plate 32; The first slot 34 is opened on the outside of the support rod 1, and the first slot 34 is located above the storage slot 31, and the first slot 34 and the insertion rod 33 cooperate with each other. The fixing plates 35 are all opened on the outside of the support rod 1, and the two fixing plates 35 are located below the storage groove 31; Pull rod 36, which is slidably fitted inside the fixed plate 35; The retaining ring 37 is slidably fitted on the outside of the support rod 1, and the top ends of the two tie rods 36 are fixedly connected to the two sides of the bottom of the retaining ring 37. The preload springs 38 are all sleeved on the outside of the pull rod 36, and the preload springs 38 are located between the fixed plate 35 and the retaining ring 37.

[0020] In practical application, when the crossbar 2 needs to be extended from the support rod 1, the crossbar 2 is first rotated 90 degrees inside the storage groove 31, causing the connecting plate 32 to rotate synchronously. Then, the connecting plate 32 is aligned with the first slot 34, and the insert rod 33 on the connecting plate 32 is inserted into the first slot 34 to fix the angle of the crossbar 2. When the crossbar 2 needs to be folded, the two pull rods 36 are first manually pulled, causing them to slide downward on the two fixing plates 35 respectively, causing the retaining ring 37 to slide downward on the outside of the support rod 1, causing the two 38 to undergo compression deformation. Then, the insert rod 33 is pulled out from the first slot 34, and the crossbar 2 is rotated 90 degrees in the opposite direction, causing the crossbar 2 to enter the storage groove 31. Then, the two pull rods 36 are released, and with the help of the elasticity of the two 38, the retaining ring 37 slides upward to limit one end of the crossbar 2, realizing the folding operation.

[0021] This embodiment uses a folding component 3 to facilitate the folding and storage of the crossbar 2 on the support rod 1, further enhancing the portability for subsequent handling by staff.

[0022] In one embodiment, 38 can be made of stainless steel, which has a certain degree of waterproof and rustproof properties.

The first external thread rod 55 passes through two circular holes 53 in sequence and is threadedly engaged with the first internal thread groove 54.

[0024] In practical application, when assembling the flood warning component 4, first insert the two inserts 52 at the top of the outer tube 41 into the two second slots 51 at the bottom of one end of the crossbar 2, so that the two round holes 53 on the two inserts 52 are on the same horizontal line as the first internal thread groove 54. Then, turn the first external thread rod 55 so that the first external thread rod 55 passes through the two round holes 53 and matches the inside of the first internal thread groove 54. When disassembling the flood warning component 4, the operation is reversed.

[0025] This embodiment provides a disassembly and assembly component 5 to facilitate the assembly or disassembly of the flood warning component 4.

[0026] In one embodiment, the first external thread rod 55 can be made of stainless steel, which has a certain degree of waterproof and rustproof properties.

The filter cylinder 63 is installed between the bottom ends of the two second external threaded rods 62; Nut 64 is threaded onto the outside of the second external thread rod 62, and the bottom of nut 64 contacts the top of the limiting plate 49.

[0028] In practical application, the two second external threaded rods 62 at the top of the filter cylinder 63 are passed through the inside of the two second internal threaded grooves 61, and then the nuts 64 are screwed onto the second external threaded rods 62, so that the nuts 64 contact the limiting plate 49, thereby fixing the filter cylinder 63 to the outside of the outer cylinder 41.

[0029] In this embodiment, by setting up the enclosure component 6, it is convenient to fix the filter cylinder 63 to the outside of the outer cylinder 41, which further facilitates the blocking of foreign objects floating on the water surface and prevents foreign objects from blocking the upward path of the float plate 411.

[0030] Please see Figure 2 and 7 In a preferred embodiment of this utility model, the protection component 7 includes: The protective box 71 is installed on top of the receiving plate 43; The ventilation holes 72 are equidistantly located on the outside of the protective box 71.

[0031] In practical application, this embodiment protects the motor 47 by providing a protective box 71 on the top of the receiving plate 43, and dissipates heat from the motor 47 by providing heat dissipation holes 72 on the inner wall of the protective box 71.

[0032] This embodiment provides a protective component 7 to facilitate the protection and heat dissipation of the motor 47, thereby extending the service life of the motor 47.
