Description

Technical Field

[0001] The utility model relates to the technical field of rainfall monitoring, and more specifically to an alarm device for monitoring rainfall in geological disasters. Background Art

[0002] ] The geological conditions in some parts of my country are quite complex, which leads to frequent geological disasters, causing certain economic losses and personal injuries to the local area. The occurrence of geological disasters is directly related to the local rainfall. The existing monitoring rain gauges are basically not suitable for use in complex geological conditions due to the terrain and observation restrictions. For example, some high-precision monitoring rain gauges have a relatively precise and complex structure, and the external conditions in the geological disaster area are harsh, which greatly shortens their service life and makes them vulnerable to damage, which greatly increases the cost of monitoring rainfall; and some simple monitoring rain gauges cannot meet the required monitoring rainfall accuracy due to the limitations of their own instruments, which makes them basically unusable in harsh geological disaster areas.

[0003] The existing patented rainfall monitoring device, patent authorization number CN205562848U, has a simple structure, and important equipment is inside the box, which is not easy to damage, thereby improving the accuracy of rainfall monitoring.

[0004] However, since the top of the water collecting funnel in patent authorization number CN205562848U is an open structure, some debris will enter the inside of the box (such as dead leaves and plastic bags) under the action of airflow, thereby blocking the overflow pipe, making it impossible to monitor the rainfall. There is still room for improvement, so we propose an alarm device for geological disaster rainfall monitoring to solve the above-mentioned problems. Utility Model Content

[0030] Example:

[0031] See also Figure 1-5 , an alarm device for monitoring rainfall in geological disasters, comprising a box body 1 and a box cover 2 installed on the top of the box body 1, and a rainwater inlet 3 is opened in the middle of the box cover 2;

[0032] A mesh cover 4 with a conical structure is installed at the rainwater inlet 3, and the root of the mesh cover 4 is symmetrically connected with a fixing ear 5 fixedly connected to the box cover 2;

[0033] The inner wall of the box body 1 is respectively installed with a first mounting frame 7 and a second mounting frame 8, and the lower surface of the mounting end of the first mounting frame 7 and the second mounting frame 8 is installed with a pressure sensor 9, a first floating block 11 is installed below the first mounting frame 7, and a second floating block 12 is installed below the second mounting frame 8, and the inner wall of the box body 1 near the first mounting frame 7 is symmetrically installed with a guide rail 10 that is slidably connected to the ends of the first floating block 11 and the second floating block 12;

[0034] It should be noted that when the alarm device for monitoring rainfall in geological disasters is in use, the pressure sensor 9 is connected to the alarm system of the control room, and the box body 1 is placed horizontally in an open area. During rainfall, rainwater enters the inner side of the box body 1 through the rainwater inlet 3 opened on the surface of the box cover 2. At the same time, the mesh cover 4 installed at the rainwater inlet 3 is used to isolate solid foreign matter, and the 4-layer conical structure of the mesh cover can make solid foreign matter slide off the surface of the mesh cover 4 to ensure that rainwater can fall into the box body 1 normally and avoid entering the inner side of the box body 1 to affect the monitoring of rainfall. By raising the water level inside the box body 1, the first floating block 11 is first floated in cooperation with the guide rail 10. When the first floating block 11 abuts against the pressure sensor 9 installed at the first mounting frame 7, a first-level alarm is triggered. As the liquid level rises, the second floating block 12 floats in cooperation with the guide rail 10 and abuts against the pressure sensor 9 installed at the second mounting frame 8, triggering a second-level alarm, thereby ensuring normal monitoring of rainfall.

[0035] like Figure 1 As shown, a liquid level window 13 is installed on the side wall of the box body 1, and the liquid level window 13 is made of transparent tempered glass. The root of the side wall of the box body 1 near the liquid level window 13 is connected to a drain pipe 14, and a stop valve is installed at the drain pipe 14;

[0036] It should be noted that the liquid level window 13 is provided to facilitate observation of the liquid level inside the box 1. When the box 1 is full of rainwater, the rainwater is drained through the drain pipe 14 by opening the stop valve to ensure subsequent rainfall monitoring.

[0037] like Figure 1 , Figure 2 As shown, the surface of the fixing ear 5 is provided with an assembly hole, and the portion of the box cover 2 corresponding to the assembly hole is provided with a screw hole;

[0038] It should be noted that the mesh cover 4 can be fixed by using screws to penetrate the assembly holes provided on the surface of the fixing ears 5 and screw them to the screw holes provided on the box cover 2 to prevent the mesh cover 4 from being blown off when the wind is strong.

[0039] like Figure 1 , Figure 3 As shown, a boss 6 is integrally formed on the edge of the lower surface of the box cover 2, and the boss 6 is arranged around a circle, and the boss 6 and the top of the box body 1 form a socket-type structure;

[0040] It should be noted that the boss 6 and the top opening of the box body 1 form a socket-type structure, which facilitates the disassembly and assembly of the box cover 2 and further facilitates the cleaning of the inside of the box body 1 .

[0041] like Figure 4 As shown, the second mounting frame 8 is located above the first mounting frame 7, and the upper surfaces of the first floating block 11 and the second floating block 12 correspond to the pressure sensor 9;

[0042] It should be noted that, as the water level inside the box body 1 rises, the first float 11 cooperates with the guide rail 10 to float up. When the first float 11 abuts against the pressure sensor 9 installed on the first mounting frame 7, the first-level alarm is triggered. As the liquid level rises, the second float 12 cooperates with the guide rail 10 to float up and abuts against the pressure sensor 9 installed on the second mounting frame 8, triggering the second-level alarm.

[0043] When in use: connect the pressure sensor 9 to the alarm system of the control room, place the box body 1 horizontally in an open area, and during rainfall, allow rainwater to enter the inner side of the box body 1 through the rainwater inlet 3 opened on the surface of the box cover 2. At the same time, use the mesh cover 4 installed at the rainwater inlet 3 to isolate solid foreign matter, and the 4-layer conical structure of the mesh cover can make solid foreign matter slide off the surface of the mesh cover 4 to ensure that rainwater can fall into the box body 1 normally, and avoid entering the inner side of the box body 1 to affect the monitoring of rainfall. Through the rising water level inside the box body 1, first make the first float 11 cooperate with the guide rail 10 to float up, when the first float 11 abuts against the pressure sensor 9 installed at the first mounting frame 7, triggering the first level alarm, with the rise of the liquid level, make the second float 12 cooperate with the guide rail 10 to float up and abut against the pressure sensor 9 installed at the second mounting frame 8, triggering the second level alarm, the model of the pressure sensor 9 is JLBU-1.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
