Description

Technical Field

[0001] The present invention relates to an automatic temperature-controlled drinking water device for pig breeding that can prevent pollution, and belongs to the technical field of pig breeding equipment. Background Art

[0002] Pig breeding is an agricultural production activity, mainly for the purpose of raising pigs for consumption. The pig breeding industry is an important industry in China's agriculture. It plays an important role in ensuring the safe supply of meat food. China's pig breeding industry is transforming from traditional pig breeding to modern pig breeding, and significant changes are taking place in both breeding models, regional layouts, production methods, and production capacities.

[0003] In the actual operation process of pig breeding, the drinking water problem is mainly solved by drinking water devices or drinking nozzles of the same specification. And in the cold season, pigs are suitable to drink warm water to promote the feed intake of pigs, increase the daily weight gain and reduce the diarrhea rate. Although there are already temperature-controlled drinking troughs on the market, when the existing pig breeding drinking troughs are actually used, since the water intake of adult pigs is generally large, and generally multiple pigs are raised in a single pigsty. As the water in the trough is drunk by pigs, the water level in the trough drops significantly, and the vertical distance between the water level and the edge of the trough will increase. And it is impossible for humans to always replenish water in a timely manner, which will affect the normal drinking of pigs. And when the existing pig breeding drinking troughs are actually used, food residues and other impurities will remain in the trough when pigs drink water. Over time, it will cause the problem of pollution of the drinking water in the trough. The existing filtering device of the drinking trough needs to replace the filter cotton regularly, the operation is relatively complicated, it is not convenient for manual use, and when replacing the filter cotton, the drinking water device needs to be stopped, which will also delay the use. Summary of the Invention

[0004] Object of the Invention: Aiming at the deficiencies existing in the use of the existing pig breeding drinking water device in the background art, the object of the present invention is to provide an automatic temperature-controlled drinking water device for pig breeding that has automatic temperature control, pollution prevention, and is convenient for pigs to fetch water.

[0005] Technical Solution: The automatic temperature-controlled drinking water device for pig breeding that can prevent pollution described in the present invention includes a base. A liftable water trough body is provided on the upper part of the base. Electric telescopic rods are fixedly provided on both sides of the water trough body. A filter screen is provided on the upper part of the electric telescopic rods. A bottom plate is provided on the front side of the base. A pressure sensor is provided inside the bottom plate. When a pig steps on the bottom plate, after the bottom plate receives the pressure signal, it can control the electric telescopic rod to shorten, driving the filter screen into the water trough body. When the pig leaves the bottom plate after drinking water, the bottom plate controls the electric telescopic rod to extend and reset, driving the filter screen to move up to filter out the pollutants in the water trough body.

[0006] Further, a water storage tank is provided at the rear side of the base. A closing plate is provided at the front end of the water outlet of the water storage tank. Both ends of the closing plate are connected to the bottom of the water tank body. The closing plate can move up and down as the water tank body rises and falls. A valve controlled by a bottom plate is provided in the water outlet of the water storage tank. When the water in the water tank body becomes less, the water tank body rises, driving the closing plate to rise. The bottom plate controls the opening of the water outlet of the water storage tank, and the water in the water storage tank is replenished into the water tank body. After the water is replenished, the closing plate moves to the outside of the water outlet of the water storage tank along with the descent of the bottom of the water tank body to close the water outlet.

[0007] Further, a folding part is provided in the middle of the water tank body. A plurality of telescopic cylinders are provided in the folding part. A telescopic airbag is provided at the bottom of the water tank body. The bottom end of the telescopic airbag is fixed on the base, and the upper end is fixed on the bottom of the tank body. An air cavity is also provided at the edge of the bottom of the tank body. The inside of the airbag is communicated with the inside of the cylinder through the air cavity. The telescoping of the cylinder can be controlled by the change of air pressure, so as to control the telescoping of the folding part.

[0008] Furthermore, both ends of the cylinder are respectively connected to the upper and lower parts of the side wall of the water tank body. The cylinder and the telescopic airbag are filled with gases with stable properties.

[0009] Furthermore, the folding part is made of a material that can be telescoped up and down.

[0010] Furthermore, the number of cylinders is more than 2.

[0011] Further, a telescopic rod body is provided inside the telescopic airbag. The telescopic rod body can freely telescope up and down to realize the change of the internal space.

[0012] Further, a piston rod is inserted into the cylinder. When the telescopic airbag extends or contracts, the air inside it enters the cylinder through the air cavity and makes the piston rod move up and down inside the cylinder, realizing the overall extension or contraction of the cylinder, and thus realizing the extension or contraction of the folding part.

[0013] Further, the filter screen is connected by a torsion spring shaft. A limiting plate is connected to the outside of the filter screen. The limiting plate is located at the top of the edge of the water tank body. When the electric telescopic rod shortens, the limiting plate is pressed to deflect the filter screen to a horizontal state and enter the water tank body. After the filter screen filters the pollutants in the water of the water tank body, the electric telescopic rod rises, and the filter screen rises to the top of the water tank body and is in an outwardly inclined state, so that the pollutants on the filter screen fall off.

[0014] Further, a temperature control device is installed at the bottom of the water tank body to control the water temperature inside the water tank body.

[0015] Further, a telescopic support rod is provided at the bottom of the water tank body. The support rod expands and contracts as the water in the water tank body increases or decreases.

[0016] Furthermore, the support rod is composed of a spring and a freely telescopic rod body. The spring is sleeved outside the rod body.

[0017] Furthermore, an outer baffle is provided outside the water tank body. The outer baffle can shield the top of the water tank body to reduce the pollution of the water inside the water tank body by the splashed dirt from the outside.

[0018] Furthermore, the power supply of the water storage tank is connected to the base, and the base is externally connected to an electric wire and can be connected to the power supply.

[0019] Furthermore, when the water level inside the water tank body is at an appropriate position, the closing plate is located outside the water outlet of the water storage tank, and the closing plate closes the water outlet of the water storage tank at this time.

[0020] Through the cooperation of the filter screen, the electric telescopic rod and the bottom plate, the present invention can realize that when the pig drinks water, the filter screen moves to the bottom inside the water tank body, and after the pig leaves the base, the filter screen flips back to the outside of the water tank body again, and realizes the effect of filtering the drinking water inside the water tank body. At the same time, by means of the vibration generated by the elasticity of the filter screen itself deflecting and restoring to its original position, the mutual separation of the filter screen and the impurities filtered out by it is promoted, and the effect of discharging the impurities is realized. At the same time, through the cooperation of the outer baffle, the anti-pollution effect of the pig breeding drinking water device can be realized, greatly reducing the influence of the impurities carried by the pig itself on the water source, thereby reducing the risk of water pollution, reducing the growth of bacteria and the spread of germs, and being beneficial to the progress of pig breeding.

[0021] Beneficial effects: Compared with the prior art, the present invention has the following remarkable advantages: (1) Through the cooperation of the filter screen, the electric telescopic rod and the bottom plate, the present invention can move the filter screen to the bottom inside the water tank body when the pig drinks water, and after the pig leaves the base, the filter screen flips back to the outside of the water tank body again, and realizes the effect of filtering the drinking water inside the water tank body. At the same time, by means of the vibration generated by the elasticity of the filter screen itself deflecting and restoring to its original position, the mutual separation of the filter screen and the impurities filtered out by it is promoted, and the effect of discharging impurities is realized. At the same time, through the cooperation of the outer baffle, the anti-pollution effect of the pig breeding drinking water device can be realized, greatly reducing the influence of the impurities carried by the pig itself on the water source, thereby reducing the risk of water quality pollution, reducing bacterial growth and pathogen transmission, and being beneficial to the progress of pig breeding. (2) Through the cooperation of the water tank body and the cylinder body, the present invention can keep the liquid level inside the water tank body unchanged as the pig drinks water, and at the same time, it can also shorten the relative distance between the top of the water tank body and the liquid level correspondingly, so as to facilitate the pig to drink the water inside the water tank body, which is beneficial to the progress of breeding; and by controlling the electric telescopic rod with the bottom plate and also controlling the water outlet of the water storage tank, the water outlet of the water storage tank can be opened after the pig leaves the bottom plate, so as to realize the supplement of the drinking water inside the water tank body by the water storage tank. And as the water in the water tank body increases, the bottom surface of the water tank body drops and the closing plate seals the water outlet of the water storage tank, achieving the effect of automatically shutting down the water storage tank and realizing the automatic water replenishment effect of the pig drinking water device, which is beneficial to the unified management and use of the device by humans. (3) By installing a temperature control device at the bottom of the water tank body, the present invention can control the water temperature inside the water tank body, thereby realizing the effect of automatic temperature control, facilitating the pig to drink warm water, being beneficial to the progress of pig breeding, reducing various problems caused by the pig drinking cold water, improving the quality of pig breeding, and facilitating operations such as unified management by humans.

Specific implementation manner

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] As Figures 1-3 shown, an automatic temperature-controlled drinking water device for pig breeding capable of preventing pollution according to the present invention includes a base 1. A liftable water tank body 2 is provided on the upper part of the base 1. The water tank body 2 is used for accommodating drinking water to facilitate pigs to drink water. Electric telescopic rods 5 are fixedly provided on both sides of the water tank body 2. A filter screen 4 is provided on the upper part of the electric telescopic rods 5. A bottom plate 7 is provided on the front side of the base 1. A pressure sensor is provided inside the bottom plate 7. When a pig steps on the bottom plate 7, after the bottom plate 7 receives a pressure signal, it will control the electric telescopic rod 5 to shorten, driving the filter screen 4 into the bottom of the water tank body 2. When the pig leaves the bottom plate 7 after drinking water, the bottom plate 7 controls the electric telescopic rod 5 to extend and reset, driving the filter screen 4 to move up to filter out pollutants in the water tank body 2.

[0032] As Figure 5As shown in the figure, a folding part 21 is provided in the middle of the water tank body 2. The upper and lower parts of the water tank body 2 are connected by the middle folding part 21. There are 2 cylinders 3 inside the folding part 21. The 2 cylinders 3 are evenly distributed inside the folding part 21 (symmetrically arranged at the front and rear ends in this embodiment), which can play a supporting role. The upper end of the cylinder 3 is fixedly connected to the side wall of the water tank body 2 above the folding part 21, and the lower end of the cylinder 3 is fixedly connected to the side wall of the water tank body 2 below the folding part 21. A piston rod 31 is inserted inside the cylinder 3. The piston rod 31 is movably connected to the inside of the cylinder 3, and the top of the piston rod 31 is fixed on the side wall of the water tank body 2 above the folding part 21. A gas chamber 22 is opened at the bottom of the water tank body 2. The top of the gas chamber 22 is communicated with the bottom of the cylinder 3, and the bottom of the gas chamber 22 is communicated with the telescopic airbag 24. The telescopic airbag 24 is a structure that can be telescoped. A telescopic rod body 241 is arranged inside the telescopic airbag 24. The telescopic rod body 241 can play a supporting and limiting role for the telescopic airbag 24. The top of the telescopic rod body 241 is fixed to the bottom of the water tank body 2, and the bottom of the telescopic rod body 241 is fixed to the base 1. The cylinder 3 and the telescopic airbag 24 are filled with gases with stable properties (air is used in this embodiment). The internal space of the telescopic airbag 24 is communicated with the inside of the cylinder 3 through the gas chamber 22. When the telescopic airbag 24 extends, its internal space shrinks, so that the air in the telescopic airbag 24 enters the cylinder 3 through the gas chamber 22, and the piston rod 31 moves inside the cylinder 3, realizing the overall elongation of the cylinder 3, and thus realizing the elongation of the folding part 21. A telescopic support rod 25 is provided at the bottom of the water tank body 2. The bottom of the water tank body 2 is connected to the base 1 through the support rod 25. The support rod 25 is composed of a telescopic spring and a telescopic rod, and plays a supporting role for the water tank body 2, so that the mass of the water tank body 2 and the water inside it acts on the support rod 25, realizing the effect that the water tank body 2 rises and falls with the amount of water inside it. At the same time, when the amount of water in the water tank body 2 decreases, the overall mass of the water tank body 2 decreases, causing the support rod 25 to extend, and at the same time the telescopic airbag 24 extends, the internal space of the telescopic airbag 24 increases, realizing the overall shortening of the cylinder 3, the folding part 21 shortens, so that the top of the water tank body 2 drops, thereby maintaining the difference between the top of the water tank body 2 and the liquid level to be generally unchanged, and also being able to maintain the liquid level in the water tank body 2 at a certain height, so that the liquid level height can be maintained at a position convenient for pigs to drink, facilitating the pigs' drinking water, and avoiding the problems that it is not convenient for pigs to drink water when the liquid level is too low or too high, or the liquid level is too low and is easily polluted by the outside world, improving the practicability and convenience of the device. A temperature control device 23 is also installed at the bottom of the water tank body 2. The temperature control device 23 can monitor and control the temperature of the water inside the water tank body 2, thereby being able to ensure the temperature of the pigs' drinking water, which is beneficial to the growth and development of pigs. At the same time, the heat generated by the temperature control device 23 will not have a great impact on the gases filled in the telescopic airbag 24 and the cylinder 3, and can ensure the coordinated movement of the telescopic airbag 24 and the cylinder 3.

[0033] As Figure 2As shown in the figure, a water storage tank 8 is provided at the rear side of the base 1. An outlet is provided at the bottom of the water storage tank 8. The outlet is located above the water trough body 2. A valve controlled by the bottom plate 7 is installed in the outlet. When a pig stands on the bottom plate 7, the valve closes, avoiding the problem of sudden water discharge from the water storage tank 8 when the pig drinks water. A closing plate 6 is arranged outside the outlet of the water storage tank 8. Both ends of the closing plate 6 are connected to the bottom of the water trough body 2, enabling the closing plate 6 to move along with the lifting and lowering of the water trough body 2. When the pig leaves the bottom plate 7, the valve in the outlet at the bottom of the water storage tank 8 opens. Since the water level inside the water trough body 2 decreases, the water trough body 2 rises. The bottom of the water trough body 2 is higher than the designated position, and the closing plate 6 also rises along with the water trough body 2. At this time, the closing plate 6 is in a state of leaving the outlet at the bottom of the water storage tank 8. At this time, the water storage tank 8 can replenish water into the water trough body 2 until the water level in the water trough body 2 returns to normal. Then the water trough body 2 descends and drives the closing plate 6 to return to its original position. At this time, the closing plate 6 closes the outlet of the water storage tank 8, realizing the automatic water replenishment function of the device, which is convenient for use and management. A power supply device is provided on the base 1 and is connected with a power cord, which can provide corresponding electric energy for the operation of the water trough body 2, the electric telescopic rod 5, the bottom plate 7, and the water storage tank 8.

[0034] As Figures 2-4 shown in the figure, the filter screen 4 is connected to the top end of the electric telescopic rod 5 through a torsion spring shaft. The electric telescopic rods 5 are symmetrically installed on the base 1 on both sides of the water trough body 2 and are controlled by the power supply on the base 1. A limiting plate 41 is connected to the outside of the filter screen 4. The limiting plate 41 is located on the outer edge of the water trough body 2. When a pig takes water through the water trough body 2, the front feet of the pig step on the bottom plate 7. After the bottom plate 7 receives the pressure signal, it will control the electric telescopic rod 5 to shorten. The limiting plate 41 will be pressed by the edge of the water trough body 2, causing the filter screen 4 to deflect. After the filter screen 4 enters the water trough body 2, the limiting plate 41 is parallel to the inner wall of the water trough body 2, and the filter screen 4 can be generally in a horizontal state and cover the inside of the water trough body 2. The filter screen 4 can move to the bottom of the water trough body 2 as the electric telescopic rod 5 shortens. When the pig leaves the bottom plate 7, the electric telescopic rod 5 extends and returns to its original position. The filter screen 4 moves upward as the electric telescopic rod 5 extends, filtering food residues and the like left by the pig when drinking water in the water trough body 2. After the external pressure of the limiting plate 41 from the water trough body 2 is removed, the filter screen 4 returns to its original position under the action of the torsion spring shaft. The limiting plate 41 contacts the top edge of the water trough body 2 again. At the same time, due to the influence of inertia when the filter screen 4 deflects itself, the filter screen 4 vibrates, causing the food residues and other impurities filtered from the water trough body 2 by the filter screen 4 to be shaken out, thus avoiding the problem that the food residues carried by the pig when drinking water are not easy to clean and easily pollute the water in the drinking trough, reducing the breeding and spread of bacteria. At the same time, it is also convenient for manual daily cleaning and maintenance, facilitating the use of the device. At the same time, setting the filter screen 4 as an external structure can facilitate its later cleaning or maintenance operations and will not delay the normal operation of the device.

[0035] AsFigure 1 As shown, an outer baffle 9 is further provided outside the water tank body 2. The outer baffle 9 can block the top of the water tank body 2 while not affecting the pigs' drinking water, reducing problems such as pollution of the water inside the water tank body 2 by splashed dirt from the outside, etc.

[0036] As Figure 6 shown, through the cooperation of the water tank body 2, the cylinder body 3, the closing plate 6 and the water storage tank 8, the operation of automatic water replenishment can be realized, and at the same time, the water level in the water tank body 2 can always be at a height convenient for pigs to drink, facilitating pigs to drink water and improving the practicability of the drinking device; at the same time, through the cooperation of the filter screen 4, the electric telescopic rod 5 and the bottom plate 7, the filtering effect of the water inside the water tank body 2 can be realized, greatly reducing the pollution problem of the water in the water tank body 2; in addition, the water storage tank 8 can also be set as a sealed structure and connected to a water pipe to realize the function of automatic water replenishment.

[0037] Working principle:

[0038] Install the pig breeding drinking water device in the drinking area of the pig breeding area and connect the power supply of the base 1 so that the base 1 can supply power to the bottom plate 7, the water tank body 2 and the electric telescopic rod 5. Open the top cover of the water storage tank 8 and add drinking water for pigs. At this time, there is no pig standing on the bottom plate 7, and the outlet valve at the bottom of the water storage tank 8 is in the open state. The water outlet of the water storage tank 8 discharges water, and the water in the water storage tank 8 enters the water tank body 2. The increase in the water inside the water tank body 2 increases its own mass, the support rod 25 is compressed and shortened, and the bottom surface of the water tank body 2 drops. The drop of the bottom surface of the water tank body 2 causes the expansion airbag 24 to be compressed, and the gas in the expansion airbag 24 enters the cylinder body 3 from the air chamber 22, causing the piston rod 31 to move upward in the cylinder body 3, realizing the elongation of the cylinder body 3, and the folding part 21 also elongates, maintaining the distance between the liquid level inside the water tank body 2 and the top of the water tank body 2 unchanged. When the water level in the water tank body 2 reaches the specified value, the closing plate 6 moves to the outside of the water outlet of the water storage tank 8 as the bottom of the water tank body 2 drops, and closes the water outlet of the water storage tank 8, realizing the closing of the water outlet of the water storage tank 8. The temperature control device 23 monitors and controls the temperature of the water inside the water tank body 2, realizing the automatic control of the water temperature inside the water tank body 2, so that the water temperature inside the water tank body 2 can be maintained at the corresponding set value. When the pig drinks water, the pig stands on the front bottom plate 7 of the water tank body 2. The bottom plate 7 is pressed and sends a signal to the electric telescopic rod 5 and the water storage tank 8. The outlet valve at the bottom of the water storage tank 8 closes, the electric telescopic rod 5 shortens, the limit plate 41 deflects under the pressure of the side wall of the water tank body 2, so that the filter screen 4 enters the water tank body 2 and covers the bottom of the water tank body 2. The pig drinks water above the filter screen 4. As the water volume inside the water tank body 2 decreases, its overall mass decreases, the support rod 25 elongates, and the expansion airbag 24 elongates. The internal space of the expansion airbag 24 increases, and the gas in the cylinder body 3 is inhaled into the expansion airbag 24 through the air chamber 22. The piston rod 31 contracts, and the folding part 21 also shortens, so that the liquid level difference between the top of the water tank body 2 and the liquid level inside the water tank body 2 remains constant. When the pig leaves the water tank body 2, the bottom plate 7 sends a signal, causing the electric telescopic rod 5 to elongate. The filter screen 4 gradually leaves the water inside the water tank body 2 and filters the water. The food residues left by the pig in the water tank body 2 are filtered by the filter screen 4. After the limit plate 41 leaves the inner wall of the water tank body 2, the external pressure is lost, and the filter screen 4 bounces to an inclined state. At the same time, the vibration when the filter screen 4 bounces causes the impurities filtered on the filter screen 4 to be ejected to the outside. When there is no pig standing on the bottom plate 7, control the outlet valve at the bottom of the water storage tank 8 to open, and the water storage tank 8 adds water to the water tank body 2 until the water volume inside the water tank body 2 makes the closing plate 6 move to the outside of the bottom water outlet of the water storage tank 8 again, and the closing plate 6 closes the bottom water outlet of the water storage tank 8, realizing the automatic replenishment effect of the drinking water inside the water tank body 2; Manual workers can add water to the water storage tank 8 regularly or automatically replenish water.
