[0003] In the pump head suction and discharge port connection method, flanges are commonly used pipe connection components. However, due to motor vibration, thermal expansion and contraction, the fastening mechanisms of the two flanges become loose, resulting in a gap between the two tightly connected flanges, causing water leakage at the connection. However, due to failure to promptly report the problem, liquid wasted and the surrounding environment was polluted.
[0004] Therefore, we offer a leak-proof pump head. Utility Model Content
[0005] The purpose of the utility model is to provide a leak-proof pump head to solve the above-mentioned technical problems, so as to achieve timely alarm of water leakage and further improve the effect of water leakage prevention.
[0006] In view of this, the present invention provides a leak-proof pump head, comprising a pump head and connecting pipes inserted in corresponding positions on the outer surface of the pump head, wherein there are at least two connecting pipes, and a first flange is inserted into the end of the connecting pipe away from the pump head, and a second flange is provided on one side of the first flange, and the first flange fits tightly with the second flange.

[0013] Compared with the prior art, the present invention provides a leak-proof pump head with the following beneficial effects:
[0014] 1. In the present utility model, the drainage tube is always in a vertical downward state, and under the guide limit of the water flow trough, the liquid flows to the drainage tube. Under the vertical action of the drainage tube, the liquid naturally flows into the water alarm along the direction of the drainage tube. When the liquid height inside the water alarm instantly exceeds the height of the two separated wires inside the water alarm, the two separated wires are energized based on the conductive principle of the liquid, and the water alarm will sound an alarm. Under the action of the water flow trough, the drainage tube and the water alarm, the staff can discover water leakage in time, reduce the later maintenance cost, and improve the practical function of the device.
[0015] 2. The utility model, under the action of the L-shaped groove, tightens and limits the first flange and the second flange at the same time. The first prevents the fastening mechanism on the flange from becoming loose due to motor vibration, which in turn causes the gap between the first flange and the second flange to be too large, resulting in water leakage. The tightness of the connection between the first flange and the second flange is ensured, and the anti-leakage function of the pump head is further improved. The second L-shaped groove fits tightly with the first flange and the second flange to prevent liquid from leaking into the external environment, thereby limiting the flow direction of the liquid.
[0016] 3. The utility model, under the action of the flexible clamping block and the hollow hexagonal clamping block, prevents the bolts and nuts from loosening due to the vibration of the motor, ensures the stability of the bolt and nut connection, and improves the leak-proof function of the pump head. At the same time, when the fixing ring and the slot are plugged in, the flexible clamping block is prevented from moving at a certain angle due to the vibration of the motor, and the angle of the flexible clamping block is limited, which further ensures the stability of the bolt and nut connection and improves the leak-proof function of the pump head.
[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0026] Embodiment: A leak-proof pump head, such as Figure 1 - Figure 5As shown, it includes a pump head 1 and a connecting pipe 2 inserted in the corresponding position of the outer surface of the pump head 1. There are at least two connecting pipes 2. The connecting pipe 2 is inserted with a first flange 3 at one end away from the pump head 1. A second flange 19 is provided on one side of the first flange 3. The first flange 3 and the second flange 19 fit tightly together. At least two fixing rings 5 are inserted with the outer surfaces of the first flange 3 and the second flange 19 at the same time, and the two fixing rings 5 are symmetrically distributed. A water flow groove 6 is provided in the center of the inner surface of the fixing ring 5, and L-shaped grooves 7 are provided at opposite ends of the inner surface of the fixing ring 5. The opposite ends of the first flange 3 and the second flange 19 are inserted into the L-shaped groove 7. A drainage tube 9 is inserted with the outer surface of one of the fixing rings 5, and a water alarm 10 is inserted with the end of the drainage tube 9 away from the fixing ring 5.
[0027] When the connection between the first flange 3 and the second flange 19 is completed, the L-shaped grooves 7 in the two fixing rings 5 are plugged into the opposite ends of the first flange 3 and the second flange 19. At this time, the L-shaped grooves 7 are tightly fitted with the opposite ends of the first flange 3 and the second flange 19. The two fixing rings 5 are tightly connected through the connecting plate 8 to complete the assembly of the fixing rings 5. When the liquid flows out from between the two flanges, it flows into the water alarm 10 through the drainage pipe 9 and issues a warning. At this time, the drainage pipe 9 is always in a vertical downward state. Under the guide limit of the water flow trough 6, it flows to the drainage pipe 9. At this time, the liquid flows into the water alarm 10 along the direction of the drainage pipe 9. When the liquid height inside the water alarm 10 instantly exceeds the height of the two separated wires inside the water alarm 10, based on the conductive principle of the liquid, the water alarm 10 When the two separated wires are energized, the water alarm 10 will sound an alarm. Under the action of the water flow trough 6, the drainage pipe 9 and the water alarm 10, the staff can detect water leakage in time, reduce the later maintenance cost, and improve the practical function of the device. At the same time, under the action of the L-shaped groove 7, the first flange 3 and the second flange 19 are tightened and limited at the same time. First, the fastening mechanism on the flange is prevented from loosening due to motor vibration, which in turn causes the gap between the first flange 3 and the second flange 19 to be too large, resulting in water leakage, ensuring the tightness of the connection between the first flange 3 and the second flange 19, and further improving the anti-leakage function of the pump head 1. The second L-shaped groove 7 fits tightly with the first flange 3 and the second flange 19 to prevent liquid from leaking into the external environment, and plays a role in limiting the flow direction of the liquid.
[0028] like Figure 1 - Figure 5 As shown, at least two connecting plates 8 are provided on the outer surfaces of the contact side of the two fixing rings 5 , and the two fixing rings 5 are tightly fitted together through the connecting plates 8 .
[0029] The two fixing rings 5 are tightly fitted together through the screw holes on the connecting plate 8 by bolt connection. The connecting plate 8 is used to facilitate the installation of the fixing rings 5 and ensure the tightness of the connection between the two fixing rings 5.
[0030] like Figure 1 - Figure 5 As shown, a plurality of connection holes are passed through the first flange 3 and the second flange 19, and bolts and nuts 13 are inserted into the plurality of connection holes.
[0031] Hollow hexagonal clamping blocks 12 are respectively inserted into opposite ends of the bolt nut 13 , and flexible clamping blocks 11 are simultaneously installed on the outer surfaces of the two hollow hexagonal clamping blocks 12 .
[0032] The flexible clamping block 11 has two opposite sides of its inner surface formed with clamping grooves 14 , and the fixing ring 5 is inserted into the clamping grooves 14 on two opposite sides.
[0033] After the first flange 3 and the second flange 19 are connected and fastened by the bolts and nuts 13, after the fixing ring 5 is installed, the flexible clamping block 11 is pulled outward to connect the hollow hexagonal clamping block 12 with the opposite ends of the bolts and nuts 13. Under the action of the flexible clamping block 11 and the hollow hexagonal clamping block 12, the bolts and nuts 13 are prevented from loosening due to the vibration of the motor, thereby ensuring the stability of the connection of the bolts and nuts 13 and improving the leakage-proof function of the pump head 1. At the same time, when the fixing ring 5 and the slot 14 are connected, the flexible clamping block 11 is prevented from moving at a certain angle due to the vibration of the motor, and the flexible clamping block 11 is angle-limited, thereby further ensuring the stability of the connection of the bolts and nuts 13 and improving the leakage-proof function of the pump head 1.
[0034] like Figure 1 - Figure 5 As shown, a limiting groove 15 is provided on the side of the first flange 3 close to the second flange 19 , and a water-expandable rubber ring 16 is provided inside the limiting groove 15 , which fits tightly against one side of the second flange 19 .
[0035] When there is a slight water leakage between the first flange 3 and the second flange 19, the water-swellable rubber ring 16 expands when exposed to water, filling the gap between the first flange 3 and the second flange 19, thereby improving the leak-proof function of the device. At the same time, the limiting groove 15 facilitates the installation and limiting of the water-swellable rubber ring 16, thereby preventing the water-swellable rubber ring 16 from being dislocated during the flange connection process.
[0036] like Figure 1 - Figure 5 As shown, a plurality of positioning grooves 18 are evenly formed on one side of the second flange 19 close to the first flange 3 , and positioning blocks 17 are inserted into the positioning grooves 18 , and the positioning blocks 17 are fixedly connected to one side of the first flange 3 .
[0037] Plugging can enable the two flanges to be quickly and accurately aligned when connected, making installation more efficient and improving the stability and reliability of the connection. When the motor is running, it will cause certain vibrations and displacements. The positioning block 17 and the positioning groove 18 can limit the relative movement between the flanges, firmly fix them, prevent loosening and dislocation, reduce damage to the gasket, and reduce the risk of leakage.
[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
