Description

Technical Field

[0001] This utility model belongs to the field of police dog training technology, specifically relating to a hard-surface training device. Background Technology

[0002] In modern policing, police dogs play an irreplaceable role in areas such as bomb detection, drug enforcement, missing persons searches, and evidence collection, thanks to their keen sense of smell. However, police dogs' olfactory recognition ability is not innate; it requires systematic and scientific training to adapt to complex and ever-changing real-world environments. Among these training challenges, the ability to distinguish smells in complex environments is the core difficulty. In real-world scenarios, target odors (such as those of explosives or drugs) are often masked by numerous interfering odors (such as human odors, food smells, and the smell of environmental debris), and the concentration and diffusion range of the target odor fluctuate significantly. This places extremely high demands on the police dogs' olfactory focus and sensitivity.

[0003] Existing methods for training police dogs' sense of smell have many limitations. For example, traditional training often relies on natural scenes (such as parks and streets) or simple containers, making it difficult to accurately reproduce the mixed environment of "target odor + multiple interfering odors". Furthermore, changes in the external environment (such as wind and temperature) can cause the odor diffusion state to be unstable, affecting the consistency of training results. The types, quantities, and odor intensities of interfering items cannot be quantitatively controlled, making it difficult to achieve step-by-step training "from single interference to multiple interferences". This can lead to police dogs being prone to identification errors when faced with complex interferences.

[0004] Therefore, a hard-surface training device was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a hard-surface trainer, a training device capable of precisely controlling the interference environment and quantitatively adjusting the intensity of target odor exposure. This is of great significance for improving police dogs' olfactory recognition capabilities in complex scenarios, shortening training cycles, and enhancing their adaptability to real-world situations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hard ground training device, including a shell, an installation ring fixedly connected to the upper surface of the shell, a breathable baffle fixedly connected to the inner side of the installation ring, and a placement cover provided on the inner side of the shell.

[0007] As a preferred embodiment of the hard-surface training device of this utility model, four sets of mounting plates are symmetrically fixedly connected to the surface of the mounting ring. Rollers are rotatably connected between each set of mounting plates. A control ring is sleeved on the surface of the mounting ring. The control ring is slidably connected to the rollers through the mounting plates. Several connecting posts are fixedly connected to the surface of the control ring. Each connecting post is provided with a control connecting plate. A sliding groove is opened on the inner side of the control connecting plate. The connecting post is slidably connected to the control connecting plate through the sliding groove. A rotating rod is rotatably connected to the lower end surface of the control connecting plate. The rotating rod passes through the mounting ring and extends to the inner side of the mounting ring. A mounting seat is rotatably connected to the end of the rotating rod away from the control connecting plate. The mounting seat is located at the center of the inner side of the mounting ring. A sealing blade is fixedly connected to the surface of the rotating rod.

[0008] In a preferred embodiment of the hard-surface training device of this utility model, a spring pin is mounted on the surface of one of the mounting plates, a control block is fixedly connected to the surface of the control ring, and the upper surface of the control ring is provided with a plurality of positioning holes that are adapted to the spring pin.

[0009] As a preferred embodiment of the hard ground training device of this utility model, the surface of the rotating rod is rotatably connected to a positioning sleeve, and the positioning sleeve is fixedly connected to the inner surface of the mounting ring.

[0010] As a preferred embodiment of the hard ground training device of this utility model, a placement net is fixedly connected to the inner side of the placement cover, a limiting strip is fixedly connected to the surface of the placement cover, and a limiting groove adapted to the limiting strip is opened on the inner side of the outer shell.

[0011] Compared with existing technologies, the beneficial effects of this invention are: the device constructs a relatively enclosed training space through its outer shell, and combined with the protective function of the breathable baffle, it can isolate external environmental factors such as wind and temperature from interfering with the diffusion of odors, ensuring a stable and controllable mixed environment of "target odor and interfering odor". Compared with traditional natural scenes or simple containers, it can accurately reproduce the complex olfactory environment in actual combat, ensuring the consistency and repeatability of training effects;

[0012] Utilizing the layered design of the placement net, different types and quantities of distracting items (such as food, sources of environmental odors, etc.) can be flexibly placed on top, and can be quickly replaced through the cooperation of limiting strips and limiting slots, achieving a tiered training approach from "single distraction to multiple distractions." This solves the problem of the inability to quantify and control the intensity of distractions in traditional training, helping police dogs gradually adapt to complex distractions and reducing recognition errors.

[0013] The opening and closing size of the sealing blades is adjusted through a transmission structure such as a control ring and a rotating rod. Combined with the positioning function of the spring pin and positioning hole, it can precisely lock the diffusion intensity of the target odor (e.g., the odor is extremely weak when fully closed, and the odor is significant when fully open). Compared to the problem of uncontrollable target odor exposure in existing technologies, this technology can simulate real-world scenarios such as "low-concentration targets being masked by strong interference," gradually improving the police dog's sensitivity to weak target odors.

[0014] The device simulates enclosed / semi-enclosed ground environments (such as corners and concealed locations), combined with controllable interference and target odor design, to more realistically recreate combat scenarios. Police dogs can adapt to this combination of complex interference and unstable target odors during training, improving their olfactory recognition accuracy and responsiveness in actual combat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0027] like Figure 1 As shown;

[0028] Hard surface training equipment.

[0029] In this implementation plan: Existing police dog olfactory training methods have many limitations. For example, traditional training often relies on natural scenes (such as parks and streets) or simple containers, making it difficult to accurately reproduce the mixed environment of "target odor + multiple interfering odors". Furthermore, changes in the external environment (such as wind and temperature) can cause unstable odor diffusion, affecting the consistency of training results. The types, quantities, and odor intensities of interfering items cannot be quantitatively controlled, making it difficult to achieve step-by-step training "from single interference to multiple interferences". This leads to police dogs being prone to identification errors when facing complex interferences. To solve this technical problem, a hard-surface training device is designed.

[0030] Furthermore:

[0031] like Figures 1 to 5 As shown:

[0032] Based on the above: including the outer shell 1, the upper surface of the outer shell 1 is fixedly connected to the mounting ring 2, the inner side of the mounting ring 2 is fixedly connected to the ventilation baffle 3, and the inner side of the outer shell 1 is provided with a placement cover 4.

[0033] In this implementation plan: the outer shell 1 is the basic framework of the entire training device, which can simulate the closed or semi-closed space in the ground environment, providing a carrier for the installation and protection of the internal structures, while reducing the interference of the external environment on the internal odor environment. The mounting ring 2 serves as the mounting base for the core functional components, providing a stable mounting position for the adjustment structures such as the sealing blade 23, and is a key load-bearing structure for realizing odor diffusion control. The ventilated baffle 3 is located inside the mounting ring 2, which not only ensures that the odor inside the device can diffuse outward so that the police dog can perceive it, but also prevents external debris from entering the device and avoiding interference with the training environment. The placement cover 4 is a key component for placing training items. Its internal space design allows for the layered placement of interference items and target items, providing a guarantee for building a basic environment for police dog olfactory training.

[0034] Furthermore:

[0035] In an optional embodiment, four sets of mounting plates 26 are symmetrically fixedly connected to the surface of the mounting ring 2. Rollers 27 are rotatably connected between each set of mounting plates 26. A control ring 21 is sleeved on the surface of the mounting ring 2. The control ring 21 is slidably connected to the rollers 27 through the mounting plates 26. Several connecting posts 212 are fixedly connected to the surface of the control ring 21. Each connecting post 212 is provided with a control connecting plate 211. A sliding groove is opened on the inner side of the control connecting plate 211. The connecting post 212 is slidably connected to the control connecting plate 211 through the sliding groove. A rotating rod 22 is rotatably connected to the lower end surface of the control connecting plate 211. The rotating rod 22 passes through the mounting ring 2 and extends to the inner side of the mounting ring 2. A mounting seat 24 is rotatably connected to the end of the rotating rod 22 away from the control connecting plate 211. The mounting seat 24 is located at the inner center of the mounting ring 2. A sealing blade 23 is fixedly connected to the surface of the rotating rod 22.

[0036] In this embodiment: Mounting plates 26 are symmetrically distributed on the surface of mounting ring 2, used to mount rollers 27, providing support and guidance for the rotation of control ring 21. Rollers 27 are rotatably connected between mounting plates 26. When control ring 21 rotates, rollers 27 rotate accordingly, reducing friction between control ring 21 and mounting plates 26, making the adjustment of control ring 21 smoother. Control ring 21 is sleeved on the surface of mounting ring 2 and is a manually adjustable operating component. Rotating control ring 21 can drive the movement of subsequent related components, thereby realizing the opening and closing adjustment of sealing blade 23. Connecting column 212 is fixed on the surface of control ring 21 and slides in the groove of control connecting plate 211, converting the rotation of control ring 21 into the oscillation of control connecting plate 211. The control connecting plate 211 cooperates with the connecting column 212 through a sliding groove, receives the power transmitted by the connecting column 212 and drives the rotating rod 22 to rotate, thus acting as an intermediary for power transmission. One end of the rotating rod 22 is rotatably connected to the control connecting plate 211, and the other end is rotatably connected to the mounting base 24. Under the drive of the control connecting plate 211, it rotates, thereby driving the sealing blade 23 to rotate. The mounting base 24 is located at the center of the inner side of the mounting ring 2 and is used to connect the end of the rotating rod 22, ensuring that multiple sets of rotating rods 22 can move synchronously and improving the stability of the structure. The sealing blade 23 is fixed on the surface of the rotating rod 22 and opens and closes as the rotating rod 22 rotates. The size of its opening and closing directly determines the diffusion intensity of the odor of the target item and is the core component for controlling the degree of odor exposure.

[0037] Furthermore:

[0038] In an optional embodiment, a spring pin 28 is mounted on the surface of one of the mounting plates 26, and a control block 29 is fixedly connected to the surface of the control ring 21. The control ring 21 has a plurality of positioning holes 210 on the upper surface of the control block 29 that are adapted to the spring pin 28.

[0039] In this embodiment: the spring pin 28 is mounted on the surface of the mounting plate 26 and has an elastic telescopic function. It can be inserted into the positioning hole 210 to fix the position of the control ring 21. The control block 29 is fixed on the surface of the control ring 21, which is convenient for trainees to hold and convenient for rotating the control ring 21 for adjustment. The positioning hole 210 is opened on the upper surface of the control ring 21 and is adapted to the spring pin 28. Different positioning holes 210 correspond to different opening and closing angles of the sealing blade 23. By inserting the spring pin 28 into different positioning holes 210, the opening and closing state of the sealing blade 23 can be locked to ensure the stability of the odor intensity during training.

[0040] Furthermore:

[0041] In an optional embodiment, a positioning sleeve 25 is rotatably connected to the surface of the rotating rod 22, and the positioning sleeve 25 is fixedly connected to the inner surface of the mounting ring 2.

[0042] In this embodiment, the positioning sleeve 25 is fixed on the inner surface of the mounting ring 2 and is rotatably connected to the rotating rod 22. It can limit and guide the rotation trajectory of the rotating rod 22, prevent the rotating rod 22 from shaking, ensure the accuracy of the opening and closing of the sealing blade 23, and thus ensure the stability of odor diffusion.

[0043] Furthermore:

[0044] In an optional embodiment, a placement net 41 is fixedly connected to the inner side of the placement cover 4, a limiting strip 42 is fixedly connected to the surface of the placement cover 4, and a limiting groove 43 adapted to the limiting strip 42 is provided on the inner side of the outer shell 1.

[0045] In this implementation scheme: the placement net 41 is fixed inside the placement cover 4 and is used to place interference items. Its mesh structure allows the odor of the interference items to diffuse downwards and mix with the odor of the target items below, simulating a complex olfactory environment. The limiting strip 42 is fixed to the surface of the placement cover 4 and cooperates with the limiting groove 43 on the inner side of the outer shell 1. It can guide the placement cover 4 to be accurately installed inside the outer shell 1, prevent the placement cover 4 from shifting, and ensure the accuracy of the placement position of the training items. The limiting groove 43 is opened on the inner side of the outer shell 1 and is adapted to the limiting strip 42. In addition to playing a guiding role, it can also make the installation and removal of the placement cover 4 more convenient, facilitate the quick replacement of interference items and target items, and improve training efficiency.

[0046] Working principle: The placement cover 4 is precisely installed inside the outer shell 1 by engaging the limiting groove 43 on the inner side of the outer shell 1 via the limiting strip 42. Interference items (such as food, environmental odor sources, etc.) are placed on the placement net 41 inside the placement cover 4, and target items (such as drug, explosive odor sources, etc.) are placed below the placement net 41. The mesh structure of the placement net 41 achieves the initial mixing of interference odor and target odor. The outer shell 1 forms a semi-enclosed space, reducing the interference of the external environment on the internal odor. The venting baffle 3 ensures that the mixed odor can diffuse to the outside of the device for the police dog to sniff. The trainer holds the control block 29 on the surface of the control ring 21, causing the control ring 21 to rotate along the surface of the mounting ring 2 (the roller 27 rolls between the mounting plates 26 to reduce rotational friction). When the control ring 21 rotates, the connecting post 212 on the surface slides in the groove of the control connecting plate 211, pushing the control connecting plate 211 to swing, thereby driving the rotating rod 2. 2. Rotate around the positioning sleeve 25 (fixed inside the mounting ring 2). When the rotating rod 22 rotates, the sealing blades 23 fixed on the surface open and close synchronously (the mounting base 24 ensures that multiple sets of rotating rods 22 and sealing blades 23 move synchronously). The diffusion intensity of the target item's odor is controlled by adjusting the size of the gap between the blades (the larger the gap, the more obvious the odor diffusion). When the sealing blades 23 are adjusted to the required opening and closing angle, the spring pin 28 on the surface of the mounting plate 26 elastically engages with the positioning hole 210 of the control ring 21, fixing the position of the control ring 21 and ensuring that the odor intensity is stable during training. When the police dog sniffs outside the device, it needs to identify the interfering odor on the placement net 41 and the target odor diffused by the sealing blades 23, gradually adapting to the complex olfactory environment. The device can achieve step-by-step training from simple to complex by changing the type of interfering object on the placement net 41 and adjusting the opening and closing degree of the sealing blades 23, thereby improving the police dog's olfactory discrimination ability in actual combat.
