Description

TECHNICAL FIELD

[0001] The application relates to a beef cattle drinking water supply system, in particular to an intensive beef cattle breeding drinking water supply system, and belongs to the field of intensive beef cattle breeding equipment. BACKGROUND

[0002] Water is an important part of the growth and development of beef cattle and is involved in the entire growth and development of beef cattle. If the cattle lack drinking water, the drinking water quality does not meet the standards, or the drinking water is contaminated with different degrees of drugs, a series of problems will occur. When beef cattle grow, water shortage will cause the following problems: the feed intake gradually decreases, the growth and development is slow, the metabolism is disordered, the growth rate of beef cattle gradually slows down, and the morbidity and mortality gradually increase.

[0003] At present, whether in intensive scale farms or small and medium-sized farms, there is a common problem of unsmooth drinking water supply. Some farms do not consider the actual water demand of cattle at different growth and development stages before planning and construction, and the construction of the farms is relatively arbitrary, the layout is unreasonable, there is no sufficient drinking water supply around the farms, the drinking water supply channel is relatively long, and especially in the summer and autumn seasons, the channel is easily contaminated by various pathogenic microorganisms, thereby causing the drinking water quality to decrease. In addition, affected by seasonal rainfall or other external factors, the utilization efficiency of the water supply channel of the farm is relatively low, and the farm cannot supply clean and healthy drinking water, which endangers the healthy growth of the entire cattle herd and the scientific use of water.

[0004] For large-scale beef cattle farms, the water source mainly comes from underground water, surface water and tap water, among which the drinking water safety coefficient of tap water is the highest. However, the drinking water required for beef cattle breeding is relatively large, so the cost of tap water is relatively high, so in the process of beef cattle breeding management, in order to reduce the breeding cost, underground water or surface water source is often used. Among them, the underground water source mainly uses deep well to extract deep stratum water, and the surface water source mainly uses flowing river water, reservoir water and lake water. In order to ensure the scientific supply of water source and the sufficiency of water source during the management of beef cattle breeding, it is necessary to ensure that there is sufficient water source around the farm during the planning and construction of the farm, which is one of the important indicators for the planning and construction of the farm. In the actual construction process, the water source of most cattle farms is contaminated to different degrees, especially when surface water is used as the drinking water source of the farm, the water taking and supplying processes will cause different degrees of water source pollution. Even if underground water source is used, the protection of underground water source is insufficient due to internal and external factors, various pollutants penetrate into the underground water layer, and the water source is seriously polluted and damaged.

[0005] Therefore in the process of breeding management, whether using surface water or groundwater, it is recommended to strictly sterilize and disinfect the drinking water before use, to ensure safety before supplying to the cattle herd.

[0006] At present, most of the large-scale farms have independent drinking water supply system, using water pump or water supply equipment to transport drinking water to the designated location of the farm, and then using water tower or pressure filling to transport water to each water tank. However, the water tower lacks regular cleaning and disinfection function during use, which can cause serious silt deposition and bacterial breeding, causing a large number of pathogenic microorganisms to reproduce, making the content of microorganisms in the water body seriously exceed the standard, causing beef cattle diarrhea disease, parasitic disease and respiratory disease, and finally causing serious harm to the healthy production of beef cattle, seriously affecting the economic benefit of beef cattle farm.

[0067] Example 1: The overall working process of the intensive beef cattle breeding drinking water supply system

[0068] The SA surface water or underground water enters the silt deposition cavity 7 through the main water inlet pipe 6, the silt and impurities such as stones are deposited in the silt deposition cavity 7, the water in the silt deposition cavity 7 enters the primary sedimentation tank 1 through the water outlet 12, and then is filtered through the filter screen 13 in the first-stage filter tank 8. The water filtered through the filter screen 13 enters the coagulation tank 2, the coagulant is discharged into the coagulation tank 2 through the coagulant discharge pipe 17, under the action of the coagulant, the suspended particles, microorganisms, organic matter and negative charged particles in the water in the coagulation tank 2 form flocculation bodies, and are discharged into the secondary filter tank 3.

The finally filtered water enters the inner sealing ring layer 182 through the through hole 53, and then flows into the disinfection tank 4 through the water outlet pipe 47. The chlorine gas generator 19 fills the generated chlorine gas into the water flowing through the disinfection tank 4. The water mixed with the chlorine gas is disinfected in the disinfection tank 4, and is finally discharged into the drinking water storage tank 5.

[0069] S2 When the water level in the drinking water storage tank 5 reaches the high water level sensor 21, the high water level sensor 21 transmits the signal to the PLC controller 9, the PLC controller 9 controls the electronic valve 14 to be closed, and the main water inlet pipe 6 stops water inlet. When the water level in the drinking water storage tank 5 reaches the low water level sensor 22, the low water level sensor 22 transmits the signal to the PLC controller 9, the PLC controller 9 controls the electronic valve 14 to be opened, and the main water inlet pipe 6 resumes the water inlet action.

[0074] SB opens the movable sludge scraper

[0075] When the valve on the sewage drain pipe 16 is opened, the PLC controller 9 controls the servo motor B56 to rotate counterclockwise, the gear disc 57 rotates counterclockwise, the "L" shaped moving plate 151 is pushed forward, the scraper 152 scrapes the impurities deposited at the bottom of the sludge settling chamber 7 to the sewage discharge slot 40, the impurities are discharged through the sewage drain pipe 16, when the "L" shaped moving plate 151 moves forward to the contact pressure B60 on the front end surface of the "T" shaped slider 59 contacts the pressure sensor B64 on the front inner wall of the "T" shaped sliding groove 63, the pressure sensor B64 transmits the signal to the PLC controller 9, the PLC controller 9 controls the servo motor B56 to stop counterclockwise rotation and start clockwise rotation, the servo motor B56 rotates clockwise, the gear disc 57 rotates clockwise, the "L" shaped moving plate 151 is pushed backward, the scraper 152 moves backward, when the "L" shaped moving plate 151 moves backward to the contact pressure B60 on the rear end surface of the "T" shaped slider 59 contacts the pressure sensor B64 on the rear inner wall of the "T" shaped sliding groove 63, the pressure sensor B64 transmits the signal to the PLC controller 9, the PLC controller 9 controls the servo motor B56 to stop clockwise rotation and start counterclockwise rotation, and so on, the scraper 152 scrapes the impurities at the bottom of the sludge settling chamber 7;

[0076] SC opens the water outlet

[0077] After the impurities in the sludge sedimentation chamber 7 are scraped clean, the valve on the sewage drain pipe 16 and the servo motor B56 are closed, and the PLC controller 9 controls the servo motor A11 to rotate counterclockwise, so that the upper rotating shaft 271 rotates counterclockwise, the threaded sleeve 32 moves downward along the threaded rod 31, and the telescopic sensing rotating shaft 27 is lengthened. When the threaded sleeve 32 moves downward to the position where the pressure sensor A30 on the upper surface of the clamping ring 29 below is in contact with the pressure sensor A34 on the lower surface of the outer edge layer 321, the pressure sensor A30 transmits the signal to the PLC controller 9, and the PLC controller 9 controls the servo motor A11 to stop working. At this time, the water outlet 12 is opened, and the next water inlet of the main water inlet pipe 6 is waiting.
