Description

Technical Field

[0001] This invention relates to the field of venom collection technology, specifically a non-contact safe collection device for highly venomous snake venom. Background Technology

[0002] Natural snake venom contains snake venom polypeptides, which have pharmacological effects such as analgesia, hemostasis, inhibition of thrombosis and anti-tumor. The main components are proteins, enzymes, small molecule peptides, amino acids, carbohydrates and so on.

[0003] In the field of highly venomous snake venom collection, traditional methods mostly rely on direct manual contact, which poses significant safety hazards and efficiency bottlenecks. Existing venom collection devices typically suffer from the following problems: High safety risks: It requires manual removal of venomous snakes or immobilization of their heads, which can easily trigger stress reactions in the snakes and lead to bites. Low collection efficiency: The fixing device lacks flexibility and is difficult to adapt to the head size of venomous snakes of different sizes, requiring repeated adjustments and affecting the workflow; Venomous snakes exhibit significant stress: mechanical restraints or sudden movements of devices can easily startle venomous snakes, causing them to refuse to release venom or to incompletely expel it. Limited functionality: Most devices only have fixed functions and lack auxiliary drainage design, relying on the snake to drain fluid on its own, which limits efficiency.

[0004] To address the aforementioned problems, this invention proposes a non-contact, safe device for collecting highly venomous snake venom. Summary of the Invention

[0005] This invention provides a non-contact safety device for collecting venom from highly venomous snakes. Through a remote-drive design with a push plate, operators only need to push the handle to guide the snake into the guide tube, avoiding direct contact with the snake and reducing operational risks from the outset. Simultaneously, a guide block and a ring spring within the guide tube form a buffer transition structure. When the snake pushes the guide block, the tension feedback of the ring spring transmits the snake's position information to a motion sensor in real time. This allows the electric telescopic rod to adjust the spacing between the fixed blocks in advance, ensuring the device is adapted before the snake arrives, avoiding stress reactions caused by real-time adjustments, thus solving the problems mentioned in the background art.

[0006] The technical solution of this invention is as follows: A non-contact safe collection device for highly venomous snake venom includes: a housing, a transparent cover on the top of the housing, a groove on the top of the transparent cover, a push plate slidably connected inside the housing, a push block fixedly connected to the bottom of the push plate, one side of the push block being right-angled, a handle fixedly connected to the top of the push plate, and the handle slidably connected inside the groove. When venom needs to be extracted, the operator pushes the push plate with the handle, causing the push plate to drive the venomous snake toward a guide tube. A through groove is formed on one side of the housing, and a guide tube is fixedly connected inside the through groove, the guide tube passing through the through groove. A baffle is slidably connected to one side of the housing in the through groove. A fixing component is provided at the end of the guide tube away from the housing, and an auxiliary component is provided inside the fixing component. The baffle is L-shaped, and a bell is fixedly connected between the baffle and the through groove. A lever is fixedly connected to the short side of the L-shaped baffle. When the baffle is pushed upward by the push block, the lever moves synchronously with the baffle, and the lever turns the bell, which rings to attract the attention of the venomous snake.

[0007] Furthermore, a fixed frame is fixedly connected to the end of the guide tube away from the through groove one. A liquid collection container is provided on the fixed frame. The liquid collection container is inclined on the fixed frame to facilitate the release of venom by the snake. A nylon film is provided at the opening of the liquid collection container. The surface of the nylon film is coated with a special meat-scented fragrance to attract the snake to release venom into the liquid collection container.

[0008] Furthermore, a guide groove is provided in the middle of the guide tube, and the guide grooves are evenly distributed on the guide tube. A guide block is slidably connected in the guide groove. The transition of the guide block reduces the fright caused to the venomous snake when the fixed block moves. An arc-shaped groove is provided on the side of each guide block away from the inside of the guide tube. A ring spring is slidably connected in the arc-shaped groove, and the ring spring passes through all the arc-shaped grooves.

[0009] Furthermore, the guide tube has an arc surface at one end inside the housing. A motion sensor is fixedly connected to one side of the guide block. When the guide block slides in the guide groove, the motion sensor controls the electric telescopic rod based on the sliding distance of the guide block, thereby adjusting the distance between the two fixed blocks in advance. This avoids adjustments after the venomous snake crawls between the two fixed blocks, preventing the snake from being startled and not moving forward, thus affecting work efficiency. The guide block has an arc surface at one end near the housing, which will not harm the snake when it enters between the guide blocks.

[0010] Furthermore, the fixing component includes a limiting block fixedly connected to one end of the guide cylinder. The limiting block has a limiting opening, which is a T-shape composed of a vertical groove and a horizontal groove. An electric telescopic rod is provided at one end of the vertical groove of the limiting block, and the electric telescopic rod is electrically connected to the motion sensor. The output end of the electric telescopic rod extends into the vertical groove of the limiting opening. An isosceles trapezoidal block is fixedly connected to the output end of the electric telescopic rod. The isosceles trapezoidal block is slidably connected in the limiting opening. A limiting groove is provided in the isosceles trapezoidal block. Right-angled trapezoidal blocks are slidably connected to both sides of the isosceles trapezoidal block in the limiting opening. The inclined surfaces of the right-angled trapezoidal blocks are slidably connected to the inclined surfaces of the isosceles trapezoidal blocks. A fixing block is fixedly connected to the ends of the two right-angled trapezoidal blocks away from the isosceles trapezoidal block.

[0011] Furthermore, the auxiliary component includes a square groove 1 formed on one side of the fixed block, a square groove 2 formed on one side of the fixed block, a sponge pad provided on one side of the fixed block in the square groove 1 to prevent damage to the venomous snake, an arc-shaped block 1 rotatably connected inside the square groove 1, multiple arc-shaped blocks 1 are provided and evenly distributed in the square groove 1, springs are fixedly connected between the two ends of the arc-shaped block 1 and the square groove 1 for resetting the arc-shaped block 1 to facilitate secondary operation, and a square groove 3 is formed in the middle of each arc-shaped block 1.

[0012] Furthermore, a fixed rod is slidably connected within the square groove 2. If the snake head is wide enough, when it contacts the fixed rod 1 and the fixed rod 2, it pushes the fixed rod 1 and the fixed rod 2 to slide into the square groove 2. The square groove 2 is slidably connected to the fixed rod 2 on one side of the fixed rod 1. One end of the fixed rod 1 passes through the square groove 3 and the limiting groove until it extends into the limiting opening. The fixed rod 1 and the fixed rod 2 are fixedly connected to a locking tooth at their ends near the square groove 1. Multiple locking teeth are provided and evenly distributed on the fixed rod 1 and the fixed rod 2. A massage sleeve is fitted on the fixed rod 1 and the fixed rod 2. The bottom of the massage sleeve has a through groove 2 of the same size as the locking teeth. Multiple arc-shaped blocks 2 are fixedly connected to the massage sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a remote-drive design with a push plate, allowing operators to guide the venomous snake into the guide tube simply by pushing the handle, thus avoiding direct contact with the snake and reducing operational risks from the outset. Simultaneously, the guide block and the annular spring inside the guide tube form a buffer transition structure. When the snake pushes the guide block to slide, the tension feedback of the annular spring can transmit the snake's position information to the motion sensor in real time. This allows the electric telescopic rod to adjust the spacing of the fixed blocks in advance, ensuring that the device is adapted before the snake arrives, avoiding stress reactions caused by real-time adjustments.

[0014] 2. This invention features an arc-shaped block and a spring structure within a fixed block. When the snake's head enters, the arc-shaped block automatically rotates or compresses the spring according to the snake's head contour, forming a flexible, enveloping fixation. Combined with a sponge pad, this further reduces pressure and effectively minimizes the snake's stress response. In addition, the tilted liquid collection container, along with the meat-scented fragrance on the nylon film, actively attracts the snake to release venom. Combined with the arc-shaped block of the massage sleeve, which simulates natural stimulation, this significantly improves the completeness of venom discharge. Attached Figure Description

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-6 As shown, the present invention provides a non-contact safe collection device for highly venomous snake venom, comprising: a housing 1, a transparent cover 2 on the top of the housing 1, a groove 21 on the top of the transparent cover 2, a push plate 3 slidably connected inside the housing 1, a push block 31 fixedly connected to the bottom of the push plate 3, one side of the push block 31 being right-angled, a handle 32 fixedly connected to the top of the push plate 3, the handle 32 slidably connected inside the groove 21, when venom needs to be extracted, the operator pushes the push plate 3 through the handle 32, causing the push plate 3 to drive the venomous snake toward the guide tube 5, a through groove 4 on one side of the housing 1, a guide tube 5 fixedly connected inside the through groove 4, the guide tube 5 passing through the through groove 4, a baffle 6 slidably connected to one side of the housing 1 in the through groove 4, a fixing component 7 at the end of the guide tube 5 away from the housing 1, and an auxiliary component 8 inside the fixing component 7; The baffle 6 is L-shaped. A bell 11 is fixedly connected between the baffle 6 and the through groove 4 in the housing 1. A lever 61 is fixedly connected to the short side of the L-shaped baffle 6. When the baffle 6 is pushed upward by the push block 31, the lever 61 moves synchronously with the baffle 6. The lever 61 tugs the bell 11, and the bell 11 rings to attract the attention of the venomous snake.

[0019] As a technical solution of the present invention, a fixing frame 41 is fixedly connected to one end of the guide tube 5 away from the through groove 4. A liquid collection tank 42 is provided on the fixing frame 41. The liquid collection tank 42 is inclined on the fixing frame 41 to facilitate the release of venom by the snake. A nylon film is provided at the opening of the liquid collection tank 42. The surface of the nylon film is coated with a special meat-scented fragrance to attract the snake to release venom to the liquid collection tank 42.

[0020] As a technical solution of the present invention, a guide groove 51 is provided in the middle of the guide cylinder 5. The guide grooves 51 are evenly distributed on the guide cylinder 5. A guide block 52 is slidably connected in the guide groove 51. Through the transition of the guide block 52, the fright caused to the venomous snake when the fixed block 77 moves is reduced. An arc-shaped groove 53 is provided on the side of each guide block 52 away from the inside of the guide cylinder 5. A ring spring 54 is slidably connected in the arc-shaped groove 53. The ring spring 54 passes through all the arc-shaped grooves 53.

[0021] As a technical solution of the present invention, the guide cylinder 5 is provided with an arc surface 521 at one end inside the housing 1. The guide cylinder 5 is fixedly connected to a motion sensor 522 on one side of the guide block 52. When the guide block 52 slides in the guide groove 51, the motion sensor 522 controls the electric telescopic rod 73 according to the sliding distance of the guide block 52, thereby adjusting the distance between the two fixed blocks 77 in advance. This avoids the need for adjustment after the venomous snake crawls between the two fixed blocks 77, preventing the venomous snake from being frightened and not moving forward, thus affecting work efficiency. The guide block 52 is provided with an arc surface 523 at one end near the housing 1, so that the venomous snake will not be harmed when it enters between the guide blocks 52.

[0022] As a technical solution of the present invention, the fixing component 7 includes a limiting block 71 fixedly connected to one end of the guide cylinder 5. The limiting block 71 has a limiting opening 72, which is a T-shaped opening composed of a vertical groove and a horizontal groove. An electric telescopic rod 73 is provided at one end of the vertical groove of the limiting opening 72 on the limiting block 71. The electric telescopic rod 73 is electrically connected to the motion sensor 522, and the output end of the electric telescopic rod 73 extends into the vertical groove of the limiting opening 72. An isosceles trapezoidal block 74 is fixedly connected to the output end of the electric telescopic rod 73. The isosceles trapezoidal block 74 is slidably connected in the limiting port 72. A limiting groove 75 is provided in the isosceles trapezoidal block 74. Right-angled trapezoidal blocks 76 are slidably connected to both sides of the isosceles trapezoidal block 74 in the limiting port 72. The inclined surface of the right-angled trapezoidal block 76 is slidably connected to the inclined surface of the isosceles trapezoidal block 74. A fixing block 77 is fixedly connected to one end of the two right-angled trapezoidal blocks 76 away from the isosceles trapezoidal block 74. The control system inside the motion sensor 522 activates the electric telescopic rod 73. The output end of the electric telescopic rod 73 extends out, pushing the isosceles trapezoidal block 74 to move towards the fixed block 77. It also pushes the two right-angled trapezoidal blocks 76 to slide to both sides within the limiting port 72 through the inclined surfaces at both ends, thereby driving the fixed block 77 to move synchronously and thus controlling the distance between the two fixed blocks 77.

[0023] As a technical solution of the present invention, the auxiliary component 8 includes a square groove 81 formed on one side of the fixing block 77, a square groove 82 formed on one side of the square groove 81, a sponge pad 83 provided on one side of the fixing block 77 to prevent damage to venomous snakes, an arc-shaped block 84 rotatably connected inside the square groove 81, multiple arc-shaped blocks 84 are provided and evenly distributed inside the square groove 81, and springs 85 are fixedly connected between the two ends of the arc-shaped block 84 and the square groove 81 for resetting the arc-shaped block 84 to facilitate secondary operation, and a square groove 86 is formed in the middle of each arc-shaped block 84.

[0024] As a technical solution of the present invention, a fixing rod 821 is slidably connected inside the square groove 82. If the snake head is wide, when it contacts the fixing rod 821 and the fixing rod 822, it pushes the fixing rod 821 and the fixing rod 822 to slide into the square groove 82. The fixing rod 822 is slidably connected to one side of the fixing rod 821 in the square groove 82. One end of the fixing rod 821 passes through the square groove 86 and the limiting groove 75 until it extends out of the limiting opening 72. Fixed rod 1 821 and fixed rod 2 822 are fixedly connected to a retaining tooth 823 at one end near the square groove 1 81. Multiple retaining teeth 823 are provided and evenly distributed on fixed rod 1 821 and fixed rod 2 822. Massage sleeve 824 is fitted on fixed rod 1 821 and fixed rod 2 822. The bottom of massage sleeve 824 has a through groove 2 825 with the same size as the retaining tooth 823. Multiple arc-shaped blocks 2 826 are fixedly connected to massage sleeve 824.

[0025] Working principle: like Figures 1-4As shown, when venom extraction is required, the operator pushes the push plate 3 with handle 32, causing the push plate 3 to drive the snake towards the guide tube 5. The push plate 3 pushes the push block 31 to move synchronously, and pushes the baffle 6 upward through the inclined surface on one side of the push block 31, opening the passage of the guide tube 5. At the same time, the lever 61 moves synchronously with the baffle 6, and the lever 61 rings the bell 11. The bell 11 rings to attract the snake's attention. Since the snake has only been provided with water and not fed for one week before venom extraction, when the snake smells the special meat-scented fragrance applied to the surface of the nylon film, it will automatically search for it, enter the guide tube 5, contact the guide block 52, and push the guide block 52. The guide block 52 slides out of the guide groove 51, while simultaneously stretching the annular spring 54. When the guide block 52 slides within the guide groove 51, the motion sensor 522 calculates in advance the possible position of the snake's head based on the sliding distance of the guide block 52, and controls the extension and retraction of the electric telescopic rod 73. This drives the isosceles trapezoidal block 74 to move along the vertical groove of the limiting opening 72, and pushes the right-angled trapezoidal blocks 76 on both sides to slide outward through the inclined plane. This adjusts the spacing of the fixing blocks 77 to a pre-tightened state that is slightly larger than the width of the snake's head, avoiding adjustments after the snake crawls between the two fixing blocks 77, and preventing the snake from being frightened and not moving forward, thus affecting work efficiency.

[0026] like Figure 3 and Figures 5-6 As shown, the control system within the motion sensor 522 activates the electric telescopic rod 73. The output end of the electric telescopic rod 73 extends, pushing the isosceles trapezoidal block 74 towards the fixed block 77. Simultaneously, the inclined surfaces at both ends push the two right-angled trapezoidal blocks 76 to slide laterally within the limiting opening 72, driving the fixed blocks 77 to move synchronously. This controls the distance between the two fixed blocks 77. After the snake head enters between the two fixed blocks 77, the output end of the electric telescopic rod 73 retracts, clamping the snake head. At the same time, the snake head contacts the arc-shaped block 84. If the snake head is exactly between the arc-shaped blocks 84, the next step can proceed directly. If the snake head is between the arc-shaped blocks 84, the next step can proceed directly. At the end of block 2 826, the two arc-shaped blocks 2 826 rotate towards each other, compressing and stretching the springs 85 at both ends respectively. This flexible fixation reduces damage to the snake's head. When the snake's head is fixed and its mouth is opened by compression, the venom gland of the snake is located on one side of the massage sleeve 824. The operator rotates the end of the fixing rod 1 821, causing the fixing rod 1 821 to drive the massage sleeve 824 to slide on the fixing rod 1 821 and the fixing rod 2 822. The arc-shaped blocks 2 826 on the surface of the massage sleeve 824 simulate natural predation stimulation in a "back to front" direction, gently massaging the tissue around the venom gland and assisting in the complete release of venom into the extraction tank 42.
