Description

Technical Field

[0001] This invention belongs to the field of hydropower station operation technology, and specifically relates to an automatic rodent-catching method for hydropower station powerhouses. Background Technology

[0002] Hydropower plants are typically located in remote mountainous areas with dense vegetation and a large population of various small animals, including snakes, rats, and insects. This is especially true for small and medium-sized hydropower stations, where investment costs are relatively low and the surrounding area is less enclosed or paved. In recent years, dozens of animal species have been cleared from inside and outside the plants. Animals primarily intrude into the plants through doors and windows. While installing wire mesh on windows can mitigate this, entrances and exits need to be kept open for personnel inspections and equipment handling.

[0003] Every year during the operation of hydropower station power plants, there are numerous incidents of small animals such as snakes and rats entering the plant and causing short circuits and power outages, including the 400V power supply. Especially in remote locations, preventing snakes and rats from entering the plant is a crucial aspect of ensuring safe production. Current measures often involve installing 30cm high, removable thresholds, which inspection personnel must cross numerous thresholds during each inspection, causing significant inconvenience. Furthermore, even with these high thresholds, snakes and rats occasionally manage to enter, and they cannot be captured. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic rodent trapping method for a hydroelectric power plant. The method can change the opening and closing state of the sticky rodent trap to prevent maintenance and operation personnel from accidentally stepping on the sticky rodent trap and causing inconvenience to the personnel. At the same time, it can efficiently trap small animals such as rats and spiders that may affect the operation of the hydroelectric power plant and ensure the safe operation of the hydroelectric power plant.

[0005] The technical objective of this invention is achieved through the following technical solution: an automatic rodent-catching method for a hydroelectric power plant building, comprising multiple sticky rodent traps installed on the inside and outside of the main entrance and exit of the hydroelectric power plant building. Each sticky rodent trap includes a sticky rodent trap body and a folding cover plate hinged to the sticky rodent trap body. Two motors are installed on one side of the sticky rodent trap body, and a crank arm is connected to the output shaft of each motor. The crank arm is fixedly connected to the folding cover plate. A limit switch is installed on the folding cover plate and is electrically connected to the motor. The limit switch is used to control the stopping of the motor after it starts. When the motor drives the folding cover plate to rotate and the folding cover plate closes with the sticky rodent trap body, the limit switch sends a stop signal to the motor, and the motor stops rotating. The invention also includes an infrared control component for controlling the starting of the motor. The infrared control component includes infrared transmitters and infrared receivers adapted to the infrared transmitters, located on both sides of the sticky rodent trap body in the opening and closing direction. At least two sets of infrared transmitters and infrared receivers are provided on each side, and the infrared transmitters are in a normally open state.

[0006] Preferably, the infrared control component is installed at a height of 8-15cm from the sticky mouse trap body.

[0007] Preferably, the control logic of the infrared control component is set as follows: when the infrared receiver signal located on the outside of the sticky mouse board body is disconnected in one of the two sets of infrared receivers on one side of the sticky mouse board body, and the infrared receiver signal close to the sticky mouse board body continues to be disconnected, it is determined that a person has entered, and at this time the motor is started to close the folding cover; when the infrared receiver signal located on the inside of the sticky mouse board body is disconnected in one of the two sets of infrared receivers on the other side of the sticky mouse board body, and the infrared receiver signal far away from the sticky mouse board body continues to be disconnected, it is determined that a person has left, and at this time the motor is started to open the folding cover to maintain the sticky mouse state.

[0008] Preferably, both the sticky mouse trap body and the folding shield have a recessed platform on their front sides, and the recessed platform contains an adhesive material for sticking mice.

[0009] Preferably, the adhesive material is sticky mouse paper.

[0010] Preferably, the adhesive material includes an attractant.

[0011] Preferably, the attractant is one or more of the following: food attractant, color attractant, taste attractant, and sex attractant.

[0012] Preferably, both the sticky mouse trap body and the recessed platform of the folding shield are provided with positioning blocks. After the folding shield rotates and covers the sticky mouse trap body, the positioning blocks located in the recessed platforms of the sticky mouse trap body and the folding shield abut against each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention provides an automatic rodent trapping method for a hydroelectric power plant, which can not only effectively trap rats and other animals and improve the operational safety of plant equipment, but also automatically detect and control the opening or closing status of the sticky trap, avoiding unnecessary trouble for operators inside the plant.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See Figure 1 , Figure 2 and Figure 3 As a preferred embodiment of the present invention, this embodiment provides an automatic rodent trapping method for a hydroelectric power plant, comprising a sticky rodent trap body 1 and a folding shield 2 hinged to the sticky rodent trap body 1. Two motors 3 are provided on one side of the sticky rodent trap body 1, and a crank arm 4 is connected to the output shaft of the motor 3. The crank arm 4 is fixedly connected to the folding shield 2. A limit switch 5 is provided on the folding shield 2, and the limit switch 5 is electrically connected to the motor 3. The limit switch 5 is used to control the stopping of the motor 3 after it starts. After the folding cover plate 2 rotates and closes with the sticky mouse trap body 1, the limit switch 5 sends a stop signal to the motor 2, and the motor 3 stops rotating; it also includes an infrared control component 8, which is used to control the start of the motor 3. The infrared control component 8 includes infrared transmitters 9 and infrared receivers 10 adapted to the infrared transmitters 9 on both sides of the sticky mouse trap body 1 in the opening and closing direction, and at least two sets of infrared transmitters 9 and infrared receivers 10 are provided on each side. The infrared transmitters 9 are in the normally open state.

[0027] In the above embodiment, the limit switch 5 is a two-position limit switch. When the two-position limit switch is closed, the upper protrusion is pressed by the sticky mouse plate body 1, the end of the limit switch changes from a protrusion to a horizontal state, and the internal position switch sends a signal to the motor to stop the motor from rotating, preventing the motor from excessively closing the sticky mouse plate.

[0028] The control logic of the infrared control component in this invention is as follows: In the open state, when the infrared receiver signal on the outside of the sticky mouse board body is disconnected from one of the two sets of infrared receivers on one side of the sticky mouse board body, and the infrared receiver signal close to the sticky mouse board body continues to be disconnected, it is determined that a person has entered, and at this time the motor is started to close the folding cover; when the infrared receiver signal on the inside of the sticky mouse board body is disconnected from one of the two sets of infrared receivers on the other side of the sticky mouse board body, and the infrared receiver signal far away from the sticky mouse board body continues to be disconnected, it is determined that a person has left, and at this time the motor is started to open the folding cover, maintaining the sticky mouse state.

[0029] like Figure 2 and Figure 5As shown, when the folded cover 2 is open, the infrared transmitter A signal is disconnected, and the infrared transmitter B signal is disconnected within 5 seconds; or the infrared transmitter D signal is disconnected, and the infrared transmitter C signal is disconnected within 5 seconds, the motor is started, and then the folded cover rotates. After the folded cover is closed in place, the limit switch sends a stop signal to the motor. At this time, the motor stops rotating, and the folded cover and the sticky mouse trap body are completely closed. Figure 2 and Figure 6 As shown, when the folded cover 2 is closed, if the infrared transmitter C signal is disconnected and the infrared transmitter D signal is disconnected within 5 seconds; or if the infrared transmitter B signal is disconnected and the infrared transmitter A signal is disconnected within 5 seconds, the motor is started, the folded cover rotates, and after the folded cover is opened to the position, the limit switch sends a stop signal to the motor, the motor stops rotating, and the folded cover and the sticky mouse plate body open.

[0030] In other cases, such as when the folding cover 2 is closed, Figure 8 As shown, when infrared transmitters D and C disconnect their signals sequentially, and infrared transmitter B disconnects its signal but infrared transmitter A does not disconnect its signal within 5 seconds; or when infrared transmitters A and B disconnect their signals sequentially, and infrared transmitter C disconnects its signal but infrared transmitter D does not disconnect its signal within 5 seconds, the motor will not start, keeping the folding cover and the sticky mouse trap body closed; Figure 1 As shown, when the folded cover is open, if the infrared transmitter A signal is disconnected and the infrared transmitter B signal is not disconnected within 5 seconds; or if the infrared transmitter C signal is disconnected and the infrared transmitter D signal is not disconnected within 5 seconds, the motor will not be started, and the folded cover and the sticky mouse plate body will remain open.

[0031] In addition, such as Figure 9 As shown, when the motor starts in the open state, if the motor working time t exceeds the normal closing time T and the limit switch does not activate, the audible and visual alarm will sound. In this case, the closing stroke of the folding cover is blocked, indicating that a mouse has been stuck and needs to be dealt with promptly.

[0032] In some preferred embodiments, see Figure 1 and Figure 2 In this embodiment, based on the above embodiment, both the sticky mouse board body 1 and the folding cover plate 2 are provided with a recessed platform 6 on their front sides, and the recessed platform 6 is provided with an adhesive material for sticking mice.

[0033] In some preferred embodiments, considering the issue of replacement, the adhesive material described in this embodiment is sticky mouse paper. When used for a period of time or when mice get stuck, the sticky mouse paper can be quickly replaced to avoid problems such as foul odor and decay of carcasses.

[0034] In some preferred embodiments, taking into account the invasive animal species and their living habits encountered in the operation of the hydropower station, the adhesive material in this embodiment includes an attractant. The attractant is one or more of the following: food attractant, color attractant, taste attractant, and sex attractant. For example, food attractant, color attractant, taste attractant, or sex attractant can be used alone, or two or more attractants can be used in combination to achieve the best trapping effect.

[0035] In some preferred embodiments, to protect the sticky mouse trap body 1, in this embodiment, positioning blocks 7 are provided in the recesses 6 of both the sticky mouse trap body 1 and the folding shield 2. After the folding shield 2 rotates and covers the sticky mouse trap body 1, the positioning blocks 6 located in the recesses 6 of the sticky mouse trap body 1 and the folding shield 2 abut against each other. After the sticky mouse trap body 1 and the folding shield 2 are closed, they abut against each other through the positioning blocks 6, preventing the sticky mouse trap body 1 and / or the folding shield 2 from breaking during transportation or accidental stepping.

[0036] like Figure 4 As shown, in some preferred embodiments, in order to prevent small animals such as mice from causing the infrared control component 8 to malfunction, in this embodiment, the infrared control component 8 is installed at a height of 8-15cm from the sticky mouse trap body, so that when a mouse passes by, the infrared signal will not be disconnected, ensuring effective mouse trapping.

[0037] Finally, 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.
