[0023] Embodiment

[0024] An embodiment of the present utility model is an automatic water replenishment system for production water, which includes a self-priming pump 2 connected to a motor 3. The self-priming pump 2 is provided with a water injection port 20 and a water outlet 21. The water injection port 20 is connected to a water collection tank 1 through a first suction pipe 10. The water outlet 21 is connected to a drain pipe 22. A plug 42 is provided at the top of the self-priming pump 2 and is connected to a second suction pipe 4. A side water pipe 43 is provided in the second suction pipe 4. The side water pipe 43 is located inside the water collection tank 1. The side water pipe 43 is successively provided with an air release valve 45 and a water pump 44.

[0025] Refer to Figure 1 , in this application, the first suction pipe 10 and the drain pipe 22 are respectively connected to the water injection port 20 and the water outlet 21 of the self-priming pump 2. The water inside the water collection tank 1 is stored by the self-priming pump 2 and then transmitted to the drain pipe 22 for production water. After the motor 3 works under the control of an external power supply to start the self-priming pump 2, a certain amount of tap water is stored inside it. At the same time, the suction lift of the self-priming pump 2 is four to five meters, which solves the problems existing in the prior art and is convenient for the use of production water in case of power failure or damage to the bottom valve 100.

[0026] Meanwhile, a second water suction pipe 4 connected to the plug 42 is arranged at the top of the self-priming pump 2. The water suction end of the second water suction pipe 4 is communicated with the tap water outlet 21, so that tap water is transmitted into the water collecting tank 1 through the second water suction pipe 4 and the side water pipe 43 for storage. The drain valve 45 directly discharges the residual water in the second water suction pipe 4 and the side water pipe 43 into the water collecting tank 1. Since the plug 42 is provided, the water in the second water suction pipe 4 is prevented from entering the self-priming pump 2, the pipeline of the second water suction pipe 4 is closed, and the sealing performance and safety performance are improved.

[0027] In order to monitor and supply water to the water collecting tank 1 in a timely manner, a liquid level monitoring component 5 for real-time monitoring is arranged in the water collecting tank 1. The liquid level monitoring component 5 includes a moving plate 54 and a travel switch 57 above the moving plate 54. The travel switch 57 is connected to the moving plate 54 through a connecting rod 56. A sliding groove 50 is formed in the inner wall of the water collecting tank 1, a fixing rod 51 is assembled in the sliding groove 50, a first slider 52 is sleeved on the fixing rod 51, the first slider 52 is fixedly connected to the moving plate 54, and a floating ball 58 is connected to the lower part of the moving plate 54 through a rope.

[0028] Refer to Figure 2 , when the water level inside the water collecting tank 1 drops, the floating ball 58 inside it drops accordingly, so as to apply a downward force to the moving plate 54 through the rope, causing the first slider 52 to move downward in the fixing rod 51, so that the moving plate 54 drives the connecting rod 56 and the travel switch 57 to move downward. When the connecting rod 56 moves downward to a certain position (that is, when the moving plate 54 moves to the bottom of the sliding groove 50), the travel switch 57 is turned on, controlling the water pump 44 to start working, injecting the water in the second water suction pipe 4 into the water collecting tank 1 through the water pump 44 for storage until the water level in the water collecting tank 1 causes the floating ball 58 to move upward under the action of buoyancy and return to the original position. At the same time, the moving plate 54 and the connecting rod 56 move upward and return to the original position, the position when the travel switch 57 contacts the top of the water tank. At this time, the travel switch 57 is disconnected and the water pump 44 stops working, then the water supply is completed.

[0029] In some preferred embodiments, a spring 59 is arranged below the first slider 52 and sleeved on the outer periphery of the fixing rod 51. The spring 59 provides an elastic supporting effect for the first slider 52, and under the condition that the liquid level is satisfied, the travel switch 57 is always located at the top of the water collecting tank 1, and the travel switch 57 is in an off state in this state.

[0030] It should be noted that the spring 59 provides a supporting force for the first slider 52, and this supporting force is less than the pulling force generated by the downward movement of the floating ball 58 on the first slider 52, and the moving plate 54 is not affected during the downward movement.

[0031] To stabilize the connection between the movable plate 54 and the first slider 52, a second slider 53 is also included. The second slider 53 is located above the first slider 52 and is provided with a reinforcing plate 55 connected to the surface of the movable plate 54. The second slider 53 and the reinforcing plate 55 provide a support point for the movable plate 54, keeping the movable plate 54 in a horizontal position and strengthening the connection between the movable plate 54 and the first slider 52.

[0032] In some preferred embodiments, the side water pipe 43 is located above the liquid level in the water collection tank 1, while the first water suction pipe 10 is located below the liquid level and is equipped with a bottom valve 100 at its end. The bottom valve 100 is activated by an external controller to discharge the water in the water collection tank 1 through the first water suction pipe 10, the water inlet 20, the self-priming pump 2, the water outlet 21, and the drain pipe 22 for use as production water. During the filling process, the self-priming pump 2 always stores a certain amount of water to serve as backup water in the event of a power outage or damage to the bottom valve 100, ensuring that normal production continues.

[0033] In some preferred embodiments, the second water suction pipe 4 is sequentially provided with a first valve 41 and a first check valve 40, and the drain pipe 22 is sequentially provided with a second valve 220 and a second check valve 221. The water inlet 20 is connected to the first water suction pipe 10, and the water outlet 21 is connected to the drain pipe 22 via flanges 23.

[0034] Specifically, the first valve 41 and the first check valve 40 are opened or closed according to the liquid level under the control of the travel switch 57, and the second valve 220 and the second check valve 221 are set to selectively open or close the pipeline according to the actual pipeline opening requirements under the control of the external controller.

[0035] The working principle of the present utility model is as follows: When in use, an external controller controls the motor 3, the bottom valve 100, the second valve 220 and the second check valve 221 to open. The water in the water collection tank 1 is drained through the first water suction pipe 10, the water injection port 20, the water outlet 21 and the drain pipe 22 under the action of the self-priming pump 2 for the use of production water. During this process, a certain amount of water is always stored inside the self-priming pump 2, which can automatically replenish water in case of power failure or damage to the bottom valve 100, without affecting subsequent work use and improving work efficiency. A liquid level monitoring component 5 is provided in the water collection tank. When the liquid level inside is relatively low, the floating ball 58 moves downward along with the liquid level, so that the moving plate 54, the connecting rod 56 and the travel switch 57 move down to the bottom of the sliding groove 50 through the first slider 52 on the fixed rod 51. The travel switch 57 is turned on to control the first valve 41 and the first check valve 40 to open, so that tap water is transmitted into the water collection tank 1. After the liquid level meets the requirements, the floating ball 58 moves upward, so that the travel switch 57 returns to its original position, and the first valve 41 and the first check valve 40 are closed, realizing the timely water replenishment of the water collection tank 1. The present utility model is communicated with the first water suction pipe 10 and the drain pipe 22 through the self-priming pump 2 to transfer the water in the water collection tank 1, and at the same time, the water inside the self-priming pump 2 is discharged through the drain pipe 22 for production. The liquid level monitoring component 5 provided in the water collection tank 1 drives the moving plate 54, the connecting rod 56 and the travel switch 57 to move according to the height of the liquid level. When the moving plate 54 moves to the bottom of the sliding groove 50, the travel switch 57 controls the water supply of the second water suction pipe 4. When the travel switch 57 is located at the top of the water collection tank 1, it is disconnected. The present utility model realizes automatic water replenishment in case of power failure or damage to the bottom valve 100, and at the same time timely supplies water to the water collection tank 1, saving manpower and time and improving production efficiency.

[0036] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Based on the technical essence of the present utility model, any simple modifications, equivalent replacements and improvements made to the above embodiments within the spirit and principle of the present utility model still fall within the protection scope of the technical solution of the present utility model.
