The utility model discloses a pond blowdown device which comprises a blowdown pipe, a detection device is fixedly arranged at the top end of the blowdown pipe, a blowdown opening is formed in one side of the blowdown pipe, and a blocking mechanism is arranged on the blowdown opening. Under the action of a detection rod, an opening, a switch, a fixing cylinder, a through hole, a floating ball, a floating rod and a floating plate, when water in a pond swells, the floating plate ascends along with the water surface and makes the floating plate touch the switch, then the switch drives the motor to be started, and under transmission of a threaded rod, a threaded sleeve, a driven gear and a driving gear, the barrier plate is moved away from the sewage draining exit, so that the sewage draining exit is blocked. When the water surface descends and the floating plate leaves the gate, the barrier plate resets, and the sewage draining exit is closed by the barrier plate to stop draining water; therefore, automatic drainage is formed, and it is ensured that the horizontal plane is in an ideal state.

Description

Technical Field

[0001] The utility model relates to the field of landscape gardening, in particular to a pond sewage discharge device. Background Art

[0002] Artificial ponds are usually set up in landscape gardens to raise ornamental fish and plants. Usually, when artificial ponds are draining sewage, water is discharged through the drain hole at the bottom of the pond. During the drainage process, due to the suction of the drain hole, fish and other animals may enter the drain hole, causing the fish to die; or plants may be blocked in the drain hole, causing the drain hole to not drain properly.

[0003] When it rains heavily, the water in the pond rises sharply and causes the water in the pond to overflow from the pond bank, washing away the fish cultured in the fish pond, causing great losses. In order to ensure the safety of the pond, a pond sewage discharge device is proposed to solve the above problem. Utility Model Content

[0009] As a further description of the above technical solution:

[0010] The blocking mechanism includes a blocking plate, which is embedded in the sewage outlet. A threaded rod is provided on the top surface of the blocking plate. The threaded rod is located in a threaded sleeve. A driven gear is provided outside the threaded sleeve. The driven gear is meshed with a driving gear. The driving gear is fixedly connected to a motor. The switch is connected to the motor electrical signal.

[0011] As a further description of the above technical solution:

[0012] The other side of the sewage pipe is connected to an external pipeline.

[0013] As a further description of the above technical solution:

[0014] A filter screen is arranged in the sewage outlet.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] Under the action of the detection rod, the opening, the switch, the fixing tube, the through hole, the floating ball, the floating rod and the floating plate, when the water in the pond surges, the floating plate rises with the water surface, so that the floating plate touches the switch, and the switch driving motor is started. Under the transmission of the threaded rod, the threaded sleeve, the driven gear and the driving gear, the blocking plate is moved away from the sewage outlet, so that the sewage outlet is in a smooth state, thereby discharging water; when the water surface drops and the floating plate leaves the switch, the blocking plate will be reset, and the sewage outlet is closed by the blocking plate to stop drainage; thus, automatic drainage is formed, ensuring that the water level is in an ideal state.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 The utility model provides an embodiment: a pond sewage discharge device, comprising a sewage discharge pipe 1, a detection device 2 is fixedly provided at the top of the sewage discharge pipe 1, a sewage discharge port 3 is provided on one side of the sewage discharge pipe 1, and a blocking mechanism 4 is provided at the sewage discharge port 3;

[0025] The detection device 2 includes a detection rod 5, an opening 6 is provided on the surface of the detection rod 5, a switch 7 is provided at the inner top of the opening 6, a fixing tube 8 is provided at the inner bottom of the opening 6, a through hole 9 is provided at the top of the fixing tube 8, a floating ball 10 is provided in the fixing tube 8, a floating rod 11 is connected to the top of the floating ball 10, and a floating plate 12 is provided at the top of the floating rod 11.

[0026] Reference Figure 1-4 The diameter of the through hole 9 is larger than that of the float rod 11 , and the diameter of the float ball 10 is larger than that of the through hole 9 .

[0027] The diameter of the through hole 9 is larger than the floating rod 11, and the diameter of the floating ball 10 is larger than the through hole 9, so as to ensure that the floating plate 12 can stably touch the switch when the water level rises.

[0028] Reference Figure 1-4 The blocking mechanism 4 includes a blocking plate 13, which is embedded in the sewage outlet 3. A threaded rod 14 is provided on the top surface of the blocking plate 13. The threaded rod 14 is located in a threaded sleeve 15. A driven gear 16 is provided outside the threaded sleeve 15. The driven gear 16 is meshed with a driving gear 17. The driving gear 17 is fixedly connected to a motor 18. The switch 7 is connected to the motor 18 by electrical signals.

[0029] Reference Figure 1-4 , the other side of the sewage pipe 1 is connected to the external pipeline.

[0030] The other side of the sewage pipe 1 is connected to an external pipeline to discharge the sewage to a designated location.

[0031] Reference Figure 1-4 A filter screen is provided in the sewage outlet 3.

[0032] A filter net is provided in the sewage outlet 3 to prevent fish from swimming out of the sewage outlet 3.

[0033] Working principle: When in use, the device is installed in the pond. As the water level rises with the rainstorm, the float 10, the float rod 11, and the float plate 12 rise with the water surface. The float 10 rises in the fixed tube 8, thereby ensuring that the float plate 12 touches the switch 7. Then the switch 7 drives the motor 18 to start, and the output end of the motor 18 drives the driving gear 17 to rotate. The driving gear 17 and the driven gear 16 are meshed and connected. Therefore, the rotation of the driving gear 17 drives the driven gear 16 to rotate, and the driven gear 16 drives the threaded sleeve 15 to rotate. Since the threaded sleeve 15 is threadedly connected with the threaded rod 14, the threaded rod 14 shrinks back into the threaded sleeve 15, thereby driving the blocking plate 13 to move out of the sewage outlet, so that the sewage outlet 3 is in an unobstructed state and the water is discharged. When the water level drops, the float plate 12 leaves the switch. Similarly, it can be known that the blocking plate 13 is reset.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
