Description

Technical Field

[0001] The utility model relates to the technical field of rainfall sensors, in particular to an embedded dry reed switch connection device based on an SL3-1 tipping bucket type rainfall sensor. Background Art

[0002] The SL3-1 tipping bucket rain sensor is a widely used automatic rainfall data observation device. It is suitable for meteorological, hydrological, environmental protection, agriculture, forestry and other related departments. The reed switch is the core component of this type of sensor and has a certain degree of vulnerability. Its damage or failure is a common and important cause of sensor failure.

[0003] Replacing the reed switch is a delicate task in the daily maintenance of the rain sensor. Since the reed switch in the SL3-1 bucket rain sensor was originally designed as a welded ear-hanging type, there are the following shortcomings in the daily maintenance work:

[0004] 1. The welding operation of the reed switch is inconvenient. The installation site is usually outdoors, lacking the welding working environment conditions. At the same time, it is difficult to grasp the retention length and welding position of the reed switch during welding, which is prone to spacing deviation. It is not easy to adjust the installation on site. At the same time, the high temperature caused by welding accelerates the oxidation of the contact point of the reed switch, affecting the life of the reed switch.

[0005] 2. The replacement (disassembly and installation) operation is cumbersome. Each time the reed switch is replaced, the connecting column connected to the sensor signal line must be removed, resulting in the loosening of multiple connections. The operation is cumbersome and the distance from the moving magnetic steel below is difficult to control, which is time-consuming and laborious. Utility Model Content

[0006] The purpose of the utility model is to provide an embedded reed switch connection device based on the SL3-1 type tipping bucket rain sensor in order to solve the above problems, as described below.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The utility model provides an embedded reed switch connection device based on an SL3-1 type tipping bucket rain sensor, comprising a rain sensor body and a reed switch, wherein two terminal posts of the rain sensor body are both provided with hanging ears, and mounting holes are provided in the hanging ears, and two electrodes of the reed switch are respectively placed in the two mounting holes.

[0009] A screw hole is provided in the hanging ear, and the screw hole is communicated with the mounting hole, and a screw is threadedly connected in the screw hole, and the screw cooperates with the inner wall of the mounting hole to clamp the reed switch electrode.

[0010] By using the above-mentioned embedded reed switch connection device based on the SL3-1 type tipping bucket rain sensor, the two screws are rotated to disengage the two screw ends from the two electrodes of the reed switch, and then the reed switch can be taken out from between the two mounting holes, and then a new reed switch is placed between the two mounting holes. The two screws are then rotated in the opposite direction to make the screw ends close to the reed switch electrodes and cooperate with the mounting holes to clamp the reed switch electrodes, thereby completing the quick replacement of the reed switch.

[0011] Preferably, one end of the screw inserted into the screw hole is designed to be a curved surface.

[0012] Preferably, a placement groove is provided on the hanging ear, and the placement groove is communicated with the mounting hole.

[0013] Preferably, an embedding groove is provided on the inner wall of the mounting hole, and the electrode of the reed switch is gap-matched with the embedding groove.

[0014] The beneficial effects are:

[0015] 1. By turning the two screws, the ends of the two screws are separated from the two electrodes of the reed switch, the reed switch is taken out from between the two mounting holes, and the new reed switch is placed between the two mounting holes. By turning the two screws in the opposite direction, the ends of the screws and the mounting holes are matched to clamp the electrodes of the reed switch, and the quick replacement of the reed switch is completed. No welding is required, which enhances the environmental adaptability of the replacement and maintenance operation, avoids mechanical and high temperature damage caused by welding operations, and is simple to replace, saving time and effort, improving the maintenance efficiency and scientificity of the reed switch, and giving full play to the overall use benefits of the SL3-1 tipping bucket rain gauge sensor.

[0016] 2. The placement slot is provided so that the electrode of the reed switch can be directly placed into the mounting hole through the placement slot, avoiding the inconvenience of the electrode having to be bent before being placed into the mounting hole, thereby further improving the convenience of replacing the reed switch.

[0017] 3. The embedded groove can accommodate at least half of the diameter of the reed switch electrode. This design can prevent the screw from being rotated too tight and the electrode from being squeezed off, thereby improving the fault tolerance of the operation of the scheme.

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] See also Figure 1-Figure 3 As shown, the utility model provides an embedded reed switch connection device based on the SL3-1 type tipping bucket rain sensor, including a rain sensor body 1 and a reed switch 3. The rain sensor body 1 adopts the SL3-1 type tipping bucket rain sensor. Two terminals of the rain sensor body 1 are equipped with hanging ears 2, which are connected to the terminals. The hanging ears 2 do not need to be disassembled after installation. Compared with the welding method, the hanging ears 2 need to be disassembled to replace the reed switch 3, which simplifies the maintenance tools and replacement steps. A mounting hole 5 is opened in the hanging ear 2, and the two electrodes of the reed switch 3 are respectively placed in the two mounting holes 5.

[0026] A screw hole is provided in the hanging ear 2 , and the screw hole is communicated with the mounting hole 5 , and a screw 4 is threadedly connected in the screw hole, and the screw 4 cooperates with the inner wall of the mounting hole 5 to clamp the electrode of the reed switch 3 .

[0027] As an optional implementation, one end of the screw 4 inserted into the screw hole is designed to be an arc surface, which can ensure that the end of the screw 4 can fit in the clearance of the inner wall of the mounting hole 5 to ensure stable clamping of the reed switch 3 electrode.

[0028] A placement slot 6 is provided on the hanging ear 2, and the placement slot 6 is connected to the mounting hole 5. The placement slot 6 can directly place the electrode of the reed switch 3 into the mounting hole 5 through the placement slot 6, avoiding the inconvenience of the electrode having to be bent before it can be placed in the mounting hole 5.

[0029] An embedding groove 7 is provided on the inner wall of the mounting hole 5 , and the electrode of the reed switch 3 is loosely matched with the embedding groove 7 .

[0030] The embedding groove 7 can accommodate at least half of the diameter of the reed switch 3 electrode. This design can prevent the screw 4 from being rotated too tight and squeezing the electrode off. Since the end of the screw 4 cannot enter the embedding groove 7, the embedding groove 7 can prevent the electrode from being squeezed off.

[0031] With the above structure, by rotating the two screws 4, the ends of the two screws 4 are separated from the two electrodes of the reed switch 3, and then the reed switch 3 can be taken out from between the two mounting holes 5, and then a new reed switch 3 is placed between the two mounting holes 5, and then the two screws 4 are rotated in the opposite direction to make the ends of the screws 4 close to the electrodes of the reed switch 3 and cooperate with the mounting holes 5 to clamp the electrodes of the reed switch 3, thereby completing the quick replacement of the reed switch 3.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
