The present invention relates to the field of livestock and poultry breeding, and discloses a urine collection device for dairy cows, comprising a urine cover and a urine collection bag; the urine cover comprises a urine inlet and a urine outlet, the urine inlet is attached to the urination port of the dairy cow, and the urine outlet is connected to the urine collection bag; the urine collection bag is tied to the waist and abdomen of the dairy cow, and a switchable urine catheter outlet is arranged below the urine collection bag. The dairy cow urine collection device provided by the present invention is used to temporarily collect the urine of the dairy cow by tying the urine collection bag to the waist and abdomen of the dairy cow according to the body shape characteristics of the dairy cow. Replacing the urinary catheter with the urine collection bag can effectively prevent the urinary catheter from being easily folded and entangled during the process of the dairy cow walking, lying down, and getting up, and does not affect the normal activities of the dairy cow, and the urine collection bag has a certain storage space and does not need to be connected to the collection bucket, thereby eliminating the tethering breeding of dairy cows restricted by ropes, further reducing the constraints on the activities of dairy cows.

The invention provides an anti-freezing faucet, and belongs to the technical field of faucets. The problems that the anti-freezing operation is inconvenient and the anti-freezing stability is poor are solved. The anti-freezing faucet comprises a valve body with a water inlet and a water outlet and a control rod which is in threaded connection with the valve body, the lower end of the control rod is located in the valve body, and the control rod can move along the center line of the control rod when rotating and control connection or disconnection of the water inlet and the water outlet. A second sealing ring abutting against the inner wall of the valve body is arranged on the peripheral side of the lower end of the control rod, the second sealing ring is located between the air inlet and the water outlet, and when the control rod controls the water inlet and the water outlet to be blocked, the second sealing ring is separated from the inner wall of the valve body and enables the air inlet and the water outlet to be communicated. The device has the advantages of good anti-freezing stability, convenience in operation and the like.
