Description

Technical Field

[0001] This utility model relates to the field of musk deer breeding technology, specifically an automated musk deer breeding drinking water device. Background Technology

[0002] In musk deer farming, automatic drinking water devices are an important component to ensure both farming efficiency and the safety of the musk deer's drinking water. For example, Chinese Patent Publication No. CN209376434U discloses an automatic drinking water device for pig farming. This device includes a water trough, a water tank, a processor, and other structures. Through components such as a water level sensor, a solenoid valve, and a heating element, it can automatically control the water level in the trough, adjust the water storage capacity in the water tank, and prevent freezing in winter, thus meeting the automated drinking water needs in the farming process to a certain extent.

[0003] However, the existing device still has shortcomings in its structural design. Its water tank adopts an open structure without any protective shielding components. This open design allows dust and debris from the breeding environment to fall directly into the water tank, contaminating the drinking water. At the same time, debris and hair generated by animal activities during the breeding process may also enter the water tank, not only affecting the hygiene of the drinking water but also potentially increasing the risk of disease for the animals after drinking it. It is difficult to fully guarantee the cleanliness of the drinking water and cannot meet the needs of breeding scenarios with high requirements for drinking water hygiene. Utility Model Content

[0004] The purpose of this invention is to provide an automated musk deer breeding drinking water device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated musk deer breeding drinking water device, comprising a base frame, a water tank and a drinking mechanism arranged sequentially in the width direction of the base frame, and a blocking mechanism mounted on the base frame and acting on the drinking mechanism. The blocking mechanism includes two baffles horizontally slidably mounted on the base frame and a driving component mounted on the side wall of the base frame. The two baffles are located at the upper and lower ends of the drinking mechanism respectively and are both connected to the driving component for transmission. The driving component drives the two baffles to move synchronously in opposite directions.

[0006] Furthermore, the drinking water device consists of multiple water tanks connected in sequence, each water tank is equipped with a water level sensor, a water pipe is connected to the outlet of the water tank, the water pipe is connected to the multiple water tanks through a branch pipe, and a water pump is installed on the water pipe.

[0007] Furthermore, the drive assembly includes a motor connected to one side of the base frame via an L-shaped bracket, and a gear rotatably connected to one side of the base frame and connected to the output shaft of the motor; two openings are provided on one side of the base frame, and L-shaped connecting plates located inside the openings and extending to the outside are connected to one side of each of the two baffles, and racks are connected to each of the two connecting plates, with the tooth surfaces of the two racks arranged opposite to each other and meshing with the gear.

[0008] Furthermore, the bottom of the base frame is provided with a water collection trough at an angle, and a water outlet pipe is connected to one side of the water collection trough. The water tank is provided with a water inlet pipe.

[0009] Furthermore, solenoid valves are installed on the water pipe, the outlet pipe, and the inlet pipe.

[0010] Furthermore, a protective cover that covers the drive assembly is detachably connected to one side of the base frame.

[0011] This utility model addresses the shortcomings of existing technologies by achieving multi-dimensional technological breakthroughs through structural innovation and functional optimization. Specific beneficial effects are as follows: (i) Ensure clean drinking water to reduce the risk of diseases in musk deer. The upper baffle of this invention covers the opening at the top of the water trough, effectively preventing dust, debris, and hair and flakes generated by the musk deer's activity from falling into the drinking water; the lower baffle seals the drainage opening at the bottom of the water trough. Only when the musk deer approaches to drink does an infrared sensor trigger the two baffles to move synchronously in opposite directions (the upper baffle moves open, and the lower baffle seals), achieving a protective mode of opening on demand and closing when not in use. This cuts off the path of drinking water contamination at the source, ensuring the drinking water remains clean and reducing the risk of disease caused by drinking contaminated water. Furthermore, the bottom of the water trough features a conical design, which, combined with the controllable opening function of the lower baffle, allows the lower baffle to automatically move open after the musk deer has finished drinking and left. Residual water in the trough can then quickly drain into the collection tank along the conical bottom, preventing stagnant water from breeding bacteria and algae and further improving the hygiene of the drinking water.

[0012] (ii) Full-process automation reduces aquaculture management costs. This invention uses a PLC controller as its core, integrating infrared sensors, water level sensors, and actuators such as solenoid valves, water pumps, and motors to automate the entire process of "musk deer approaching - baffle opening - quantitative water supply - musk deer leaving - baffle closing - residual water draining - water tank replenishment - wastewater recycling." It eliminates the need for manual operation of water tanks, cleaning of residual water, or frequent water replenishment by breeders, significantly reducing labor intensity and making it particularly suitable for the high-efficiency management needs of large-scale musk deer farms.

[0015] This utility model provides an automated drinking water device for musk deer farming, aiming to solve the problems of frequent manual intervention and easy contamination of drinking water in traditional musk deer farming drinking water devices. The following is in conjunction with the appendix... Figure 1-5 The specific embodiments of this utility model will be described in detail below.

[0016] This drinking water device uses a base frame 1 as its core support. The base frame 1 consists of an L-shaped plate 20 and two vertical plates 21 connected to it. Along the width of the base frame 1, a water tank 2 and a drinking mechanism are arranged sequentially between the L-shaped plate 20 and the two vertical plates 21. The water tank 2 serves as a water storage device, and the drinking mechanism provides direct drinking water for the musk deer. The base frame 1 is also equipped with a shielding mechanism that acts on the drinking mechanism to switch between open and closed states, ensuring the cleanliness of the drinking water. Two upright plates 21 are bolted together at their bottom to form a water collection tank 14. The inner wall of the water collection tank 14 is inclined along its length (5° angle for easy wastewater collection). One end (lower end) is connected to a water outlet pipe 15, with a normally closed solenoid valve 17 connected in series on the water outlet pipe 15. A liquid level sensor (connected to a PLC controller) can be built into the water collection tank 14. When the wastewater in the water collection tank 14 reaches a preset level (e.g., 2 / 3 of the total volume), the PLC controller controls the solenoid valve 17 on the water outlet pipe 15 to open, discharging the wastewater into the wastewater treatment system of the breeding area to prevent wastewater overflow and environmental pollution. An infrared sensor 19 is mounted on the outside of the base frame 1 to detect the approach of the musk deer and trigger the automated process. Details are as follows: Water tank 2 is made of food-grade stainless steel (to avoid water pollution and the risk of musk deer accidentally ingesting it). Its volume is set according to the breeding scale (usually 50-100L, suitable for the daily drinking water of 5-10 musk deer). It consists of a tank body and a detachable lid connected to the top of the tank body. The lid has an inlet pipe 16 connected to an external water source, with a solenoid valve 17 connected in series on the inlet pipe 16 to control the supply of water to water tank 2 from an external water source (such as the breeding area's water supply system). The outlet at the bottom of the tank body is connected to a water valve via a flange. Pipe 6 is connected in series with a water pump 8 and a solenoid valve 17. The water pump 8 is a low-noise submersible pump (noise ≤40dB, to avoid stress on the musk deer). The solenoid valve 17 is normally closed and is used to control the water supply from the water tank 2 to the drinking mechanism. The tank has a built-in liquid level sensor (connected to the PLC controller, not shown in the figure) to monitor the water level in the water tank 2 in real time. When the water level is lower than the preset threshold (such as 1 / 3 of the total volume), the solenoid valve 17 on the inlet pipe 16 is triggered to open and replenish water.

[0017] The drinking system consists of 3-5 water troughs 4 connected in sequence (the number can be adjusted according to the breeding density). Multiple water troughs 4 are fixed between two upright plates 21 by bolts, and adjacent water troughs 4 are connected by snap-fit ​​connections for easy disassembly and cleaning (musk deer breeding requires regular disinfection). Each water trough 4 has a volume of 2-3L, suitable for the single drinking volume of a single musk deer. Each water trough 4 has a conical bottom design (60° cone angle) with a 20mm diameter drainage opening at the bottom for rapid drainage of residual water. An ultrasonic water level sensor 5 (model optional HC-SR04, measurement accuracy ±1mm) is embedded in the inner wall of the water trough 4 for real-time monitoring of the water level. The end of the water pipe 6 furthest from the water tank 2 is connected to a branch pipe 7 (using a multi-port PVC pipe, with the number of branches matching the number of water troughs). Each branch of the branch pipe 7 connects to the inlet of one water trough 4, ensuring uniform water supply to each water trough 4.

[0018] The shielding mechanism consists of two horizontally arranged baffles 3 and a drive assembly.

[0019] The baffle 3 is made of transparent acrylic sheet (5mm thick, which facilitates observation of the water level in the tank and provides sufficient strength). Two baffles 3 are located at the upper and lower ends of the drinking mechanism, respectively. The upper baffle 3 covers the upper opening of the water tank 4 to block dust, debris, or prevent the musk deer from trampling and contaminating the drinking water. The lower baffle 3 corresponds to the bottom drainage opening of the water tank 4 and is used to control the sealing and opening of the drainage opening. A sliding groove (T-shaped cross-section) is provided on the base frame 1 at the position corresponding to the baffle 3. The edge of the baffle 3 is embedded in the sliding groove and can slide horizontally along the groove. The sliding resistance is ≤5N, ensuring smooth movement of the baffle 3.

[0020] The drive assembly, consisting of an L-shaped frame 9, a gear 11, an L-shaped connecting plate 12, and a rack 13, is used to drive the two baffles 3 to move synchronously in opposite directions. The L-shaped frame 9 (made of lightweight and rust-proof aluminum alloy) is bolted to one side of the base frame 1. A motor 10 (specifically a stepper motor with self-locking function and adjustable speed) is fixed to the L-shaped frame 9 via a motor mount to ensure smooth baffle movement and avoid noise. The output shaft of the motor 10 is connected to the gear 11 (module 2, 20 teeth) via a coupling. The gear 11 is rotatably connected to the side wall of the base frame 1 via bearings. Two rectangular openings (the spacing matches the gear diameter) are provided on the side wall of the base frame 1 corresponding to one side of the two baffles 3. An L-shaped connecting plate 12 (made of stainless steel) is welded to the same side of each baffle 3. One end of the connecting plate 12 extends through the opening to the outside of the base frame 1 and is bolted to the rack 13 (module 2, length matching the baffle sliding stroke). The teeth of the two racks 13 are arranged opposite each other and mesh with the gear 11. When the motor 10 rotates forward, the gear 11 drives the upper rack 13 to move away from the water tank 4 (the upper baffle moves away and the water tank opens), and at the same time drives the lower rack 13 to move closer to the water tank 4 (the lower baffle blocks the drainage opening); when the motor 10 rotates in reverse, the two racks 13 move in opposite directions, realizing the closure of the water tank 4 and drainage.

[0021] A protective cover 18 (made of ABS plastic) is detachably connected to one side of the base frame 1 via a buckle. The cover has heat dissipation holes. The protective cover 18 completely covers the outside of the drive component to prevent the musk deer from accidentally touching the gears, racks and other transmission components and avoid injury; it also blocks dust and feces in the breeding environment from contaminating the drive component and extends its service life; and it helps to reduce the noise of the motor 10 during operation, further optimizing the musk deer breeding environment.

[0022] The core of the electrical control system of this device is a PLC controller (Siemens S7-200 SMART model is optional, compatible with multiple sensors and actuators). Infrared sensor 19, the liquid level sensor in water tank 2, the ultrasonic water level sensor 5 in water tank 4, and the liquid level sensor in collection tank 14 are all connected to the input terminal of the PLC controller via signal lines, transmitting sensing signals to the PLC in real time. Motor 10 (connected via a motor driver), water pump 8, solenoid valve 17 of inlet pipe 16, solenoid valve 17 of water pipe 6, and solenoid valve 17 of outlet pipe 15 are all connected to the output terminal of the PLC controller via control lines, receiving control commands from the PLC to achieve start / stop or state switching.

[0023] In addition, the electrical control system is also equipped with emergency manual switches (such as emergency stop of the water pump and manual switching of the baffle). When the automatic system fails, the basic drinking water needs of the musk deer can be guaranteed through the manual switch.

[0024] The specific working process of this utility model is as follows: Based on the drinking habits of the musk deer (usually drinking 3-4 times a day, for 5-10 minutes each time), the automated workflow of this device is as follows, requiring no manual intervention throughout: 1. The musk deer's proximity triggers the drinking process. When the musk deer approaches the drinking mechanism, the infrared sensor 19 on the outside of the base frame 1 detects the musk deer signal (sensing distance 1-2m, to avoid false triggering) and transmits the signal to the PLC controller. After receiving the signal, the PLC controller delays for 0.5s (to avoid misoperation due to the musk deer not being stable), and sends a forward rotation command to the motor 10. The motor 10 drives the gear 11 to rotate, and through the rack and pinion 13, the upper baffle 3 moves along the slide groove away from the water tank 4 (closer to the water tank), removing the upper opening of the water tank 4 (moving stroke 15-20cm, ensuring that the musk deer's head can easily reach in to drink); the lower baffle 3 moves along the slide groove towards the water tank 4 (away from the water tank), completely blocking the bottom drainage opening of the water tank 4; after the motor 10 rotates to the correct position (with feedback signal from the motor's built-in encoder), the PLC controller simultaneously sends an opening command to the solenoid valve 17 on the water pump 8 and water pipe 6, and the water in the water tank 2 flows into each water tank 4 through the water pipe 6 and the diversion pipe 7. The ultrasonic water level sensor 5 in the water tank 4 detects the water level in real time. When the water level reaches the preset threshold (such as 2 / 3 of the water tank volume to prevent water from overflowing), the water level sensor 5 sends a signal to the PLC controller. After receiving the water level compliance signal, the PLC controller sends a closing command to the water pump 8 and the solenoid valve 17 of the water pipe 6 to stop supplying water to the water tank 4, so that the musk deer can drink water normally.

[0025] 2. The departure of the musk deer triggers the cleaning process. After the musk deer finishes drinking and leaves, the infrared sensor 19 cannot detect the musk deer signal. After 3 seconds, it sends a departure signal to the PLC controller. Upon receiving the departure signal, the PLC controller sends a reverse command to the motor 10. The motor 10 drives the gear 11 to rotate in the opposite direction. Through the rack and pinion 13, the upper baffle 3 moves along the slide towards the water tank 4 (away from the water tank), completely covering the upper opening of the water tank 4 to prevent dust and debris from falling into the water tank. The lower baffle 3 moves along the slide away from the water tank 4 (away from the water tank), opening the drainage opening at the bottom of the water tank 4. The residual water in the water tank 4 (to avoid long-term storage and bacterial growth) flows into the lower collection tank 14 along the conical bottom. After the motor 10 reverses to its final position, the PLC controller records the start time of this drainage. If the collection tank 14 has not reached the liquid level threshold, it can wait for the next drainage before being processed.

[0026] 3. Water tank replenishment and water collection trough drainage The liquid level sensor in water tank 2 monitors the water level in real time. When the water level is lower than the preset threshold (such as 1 / 3 of the total volume), it sends a water shortage signal to the PLC controller. The PLC controller controls the solenoid valve 17 on the water inlet pipe 16 to open, and the external water source replenishes water to water tank 2. When the water level reaches the preset upper limit (such as 9 / 10 of the total volume), the liquid level sensor sends a full water signal, and the PLC controller closes the solenoid valve 17 on the water inlet pipe 16 to stop replenishing water.

[0027] The liquid level sensor in the water collection tank 14 monitors the sewage volume in real time. When the sewage reaches the preset liquid level (such as 2 / 3 of the total volume), it sends a drainage signal to the PLC controller. The PLC controller controls the solenoid valve 17 on the outlet pipe 15 to open, and the sewage is discharged into the treatment system. When the liquid level is lower than the preset lower limit (such as 1 / 10 of the total volume), the PLC controller closes the solenoid valve 17 on the outlet pipe 15 and stops the drainage.

[0028] All moving parts (motor, water pump) of this device are selected from low-noise models, and the protective cover 18 has an auxiliary noise reduction function. Gears 11 and rack 13 are made of modified nylon materials (such as PA66 + glass fiber reinforcement), and the tooth tips and roots of gears 11 and rack 13 are edge-trimmed (approximately 0.05-0.1mm) to eliminate sharp corners and reduce tooth tip impact noise at the start and disengagement of meshing, especially avoiding meshing impact during forward and reverse switching of the motor. The inner wall of the protective cover 18 is lined with 1mm thick polyurethane sound-absorbing cotton (sound absorption coefficient ≥0.6, targeting noise in the 200-1000Hz frequency band, which is the main noise frequency band of gear and rack meshing), absorbing internal reflected noise generated during meshing and preventing noise resonance amplification within the protective cover. The overall noise level during operation is ≤50dB, meeting the requirements of the breeding environment for musk deer (timid and sensitive to noise).

[0029] The water tank 4 is designed to be detachable and can be removed weekly for cleaning and disinfection with a neutral disinfectant (such as potassium persulfate compound); the protective cover 18 can be removed at any time for dust removal and maintenance of the drive components; If the temperature in the breeding environment is below 0℃ in winter, insulation cotton can be wrapped around the outside of water pipe 6 and branch pipe 7 to prevent the water pipe from freezing and blocking it. A heating pipe can be installed inside the water tank 4 to ensure normal water supply in winter.

[0030] This specific implementation method, through modular structural design, gear and rack synchronous transmission, and multi-sensor linkage control, realizes the full automation of the musk deer's drinking water process, including automatic start-up, quantitative water supply, automatic cleaning, and wastewater recycling. This not only reduces the labor intensity of breeders but also ensures the cleanliness of drinking water, effectively meeting the breeding needs of musk deer.
