Description

Technical Field

[0001] The utility model relates to the field of rodent prevention in hydropower stations, in particular to an automatic induction rodent prevention device used in hydropower stations. Background Art

[0002] The rat guard is an important equipment in a hydropower station. Its function is to prevent rodents (such as mice, water rats, etc.) in the reservoir of the hydropower station from entering the turbine generator or hydropower station equipment, thereby causing equipment damage or malfunction.

[0003] Most traditional hydropower stations use slot-type rat guards. When workers enter and exit doors with rat guards, they need to lift their legs to cross them, which can easily lead to bumps and trips. When large-volume goods need to be moved by cart, the rat guards need to be manually removed, and there is a possibility that they forget to restore them after removal, which makes the rat guards fail to play their due role. During the maintenance period, construction workers need to frequently remove the rat guards, which causes increased wear on the rat guard slots and a sharp reduction in their service life. At the same time, with the advancement of the current smart power plant construction work, robot inspections have gradually been put into the daily inspection work of hydropower stations. Manually opened and closed rat guards will affect the passage of robots and limit their inspection scope.

[0004] In summary, in order to solve some of the drawbacks of the traditional mouse guard that is opened and closed by manual intervention, it is necessary to provide an automatic sensing opening and closing mouse guard device to solve the above problems. Utility Model Content

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] This embodiment proposes an automatic sensing rat-blocking device for a hydropower station, which can overcome the problems of insufficient automation, limited installation environment, and insufficient flexibility of existing hydropower station rat-blocking boards; Figure 1 to Figure 3 The following are the structures of several commonly used mouse guards in the prior art.

[0034] Figure 1 The figure shows a traditional slot-type mouse guard, which is usually equipped with an aluminum alloy mouse guard main board and two side slots. The slots are fixed to the walls on both sides, and the main board is vertically inserted into the slots. The removal and installation of the mouse guard is usually completed by vertically extracting (inserting) the main board from the ground. However, this style of mouse guard has problems such as easy collision and tripping of people crossing over, manual removal is required, and repeated removal and installation will affect the service life.

[0035] Figure 2 The telescopic mouse guard is shown, which is equipped with a telescopic mouse guard main board. The main board is composed of two parallel sliding baffles spliced ​​by a connector. The mouse guard is opened and closed by fixing one side to the wall and sliding to adjust the staggered position of the first baffle and the second baffle. However, although this type of mouse guard solves the problem of slot wear, when the mouse guard is opened, the space at the overlapped part of the first baffle and the second baffle is impassable, which restricts the passage of large objects such as carts.

[0036] Figure 3 The figure shows a rotating rat guard. By modifying the slot of the traditional rat guard, the rat guard is changed to a fixed side of the wall, and the rat guard rotates around the fixed side to complete the opening and closing of the rat guard. However, the on-site installation conditions are complicated, and it is very easy to have uneven ground, expansion joints in the direction of rotation of the rat guard, etc., which hinder the opening and closing of the rat guard, making the installation of this style of rat guard limited.

[0037] Therefore, in view of the problems existing in the prior art, the present invention proposes an automatic sensing mouse-repelling device for a hydropower station. Figure 4 As shown, the utility model is an automatic sensing mouse-blocking device for a hydropower station, comprising:

[0038] Column 2;

[0039] A rat-proof door 1, wherein the rat-proof door 1 is arranged between adjacent columns 2;

[0040] The driving device 3 is connected to the rat-blocking door 1;

[0041] At least one microwave sensor 4 is disposed on the pillar 2 .

[0042] The first and second slots 6 and 5 are provided on opposite sides of the column 2 for limiting the position of the mouse-blocking door 1. Figure 4 As shown, in this embodiment, two columns 2 are arranged in parallel with each other, and the columns 2 are arranged in a C shape. A first card slot 6 and a second card slot 5 are respectively opened in the columns 2.

[0043] The rat-blocking door 1 is a foldable door, which is formed by a plurality of PVC plates connected in a flexible manner, wherein one end of the foldable door is fixedly connected to the first card slot 6, and the other end is connected to the driving device 3. The width of the foldable door is smaller than the width of the first card slot 6 and the second card slot 5. The rat-blocking door 1 of the device is formed by a plurality of PVC plates whose width is smaller than the width of the first card slot 6 and the second card slot 5, which are assembled by elastic flexible connection. One end of the rat-blocking door 1 is fixed in the first card slot 6 by screws, and the other end is fixed to the driving device 3, and the driving device 3 is used to perform the telescopic and folding movement of the rat-blocking door 1 to open and close the door.

[0044] The PVC material used has good corrosion resistance and weather resistance, and can adapt to the changing working environment of the hydropower station. Its non-conductive nature also reduces the risk of electrical fires, ensuring the safe operation of the hydropower station. The design of the foldable structure significantly reduces the space occupied by the door body when it is folded into a compact state, especially in environments with limited installation conditions such as hydropower stations. Compared with the traditional fixed-axis rotating mouse guard, it avoids the situation where there are obstacles on the side of the door opening and closing direction. At the same time, because the door body can be folded to a smaller volume, compared with wooden and steel mouse guards, it greatly simplifies the transportation and installation process, and to a certain extent, reduces the installation time and labor costs.

[0045] The driving device 3 includes a controller, a motor, a limit module and a signal receiving module. The controller is connected to the motor, the limit module and the signal receiving module respectively, and the signal receiving module is connected to the microwave sensor 4. In this embodiment, the controller is an Arduino microcontroller, the limit module adopts an HC-SR04 ultrasonic ranging module, and the signal receiving module is a 433MHz wireless radio frequency. The signal receiving module is connected to the microwave sensor 4, and the microwave sensor 4 recognizes the signal to transmit the door opening signal to the controller. The controller controls the motor to drive the door body to fold and retract toward the door opening side. When the motor reaches the limit position of the second card slot 5 (see Figure 5 ), the limit module sends a command to the controller, the controller controls the motor to stop moving, and completes the opening of the mouse guard. When the mouse guard is opened for more than a predetermined opening time (the opening time is generally set to 10S to 30S), the controller controls the motor to stretch toward the door closing side. When the drive device 3 moves into the second slot 5, the controller controls the motor to stop moving, and at the same time connects the second slot 5 to the drive device 3 through the connecting device to complete the closing of the mouse guard.

[0046] The driving device 3 also includes a moving device, which includes at least one group of pulleys 9 and a slide rail 8 matching the pulleys 9. The pulleys 9 are arranged at the bottom of the driving device 3; the slide rail 8 is arranged between adjacent columns 2, and the pulleys 9 move on the slide rail 8. The slide rail 8 is made of rubber. The moving device is used to fix the movement direction of the driving device 3. By paving the slide rail 8 made of rubber, on the one hand, the noise generated by the friction of the pulley 9 of the driving device 3 during the opening of the mouse-blocking door 1 can be reduced, and on the other hand, the friction loss of the pulley 9 can be reduced to a certain extent, thereby improving the service life.

[0047] The drive device 3 and the second card slot 5 are connected by a connecting device 7. The connecting device 7 is connected by magnetic attraction. Figure 5 As shown, the connecting device 7 of this embodiment is preferably magnetically connected, but is not limited to this. It can be adhesion or snap connection. The positive pole of the magnetic device is installed on the surface of the driving device 3, and the negative pole of the magnetic device is installed in the second slot 5. The positive pole corresponds to the negative pole. When the driving device 3 moves into the second slot 5, the positive pole and the negative pole are connected, so that the driving device 3 is connected to the second slot 5, and the rat-proof door 1 is closed.

[0048] The microwave sensor 4 is arranged on the column 2 at a distance from the ground, wherein the sensing probe of the microwave sensor 4 is arranged upward at 45°. The microwave sensor 4 of this embodiment is LG-T04, and the microwave sensor 4 is installed to one side of the surface of the column 2, and the sensing probe is arranged at an elevation angle of 45° upward, and is used to sense the staff and patrol robots entering and leaving. When the microwave sensor 4 detects a moving object at a certain distance in front, it sends a door opening control signal to the signal receiving module in the driving device 3, and the signal receiving module transmits the door opening signal to the controller to control the motor to move to the door opening side, thereby realizing the automatic opening of the door body. Compared with the traditional manual intervention to open and close the mouse guard plate, it effectively reduces manual operation and reduces the consumption of human resources, and improves the automated management of hydropower station facilities to a certain extent, and provides strong technical support for the efficient and environmentally friendly operation of the hydropower station. Working principle: Under normal conditions, that is, when the utility model is in the mouse-blocking state, the mouse-blocking door 1 of the utility model is in the open state, and the mouse-blocking door 1 is in the stretched state (such as Figure 4 shown).

[0049] When the on-site staff or the inspection robot needs to enter or exit, the microwave sensor 4 can sense the moving object and send a door opening signal to the signal receiving module. The signal receiving module transmits the door opening signal to the controller. The controller controls the motor to move, thereby driving the mouse blocking door 1 to move from the stretched state to the retracted state, and stops when it moves to the distance set by the limit module (such as Figure 5 When the on-site staff or the inspection robot enters or exits, the controller controls the motor to move, thereby driving the mouse-blocking door 1 to move from the contracted state to the stretched state, so that the device returns to the mouse-blocking state.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
