[0038] like Figures 1 to 8 As shown, the present invention provides a ship RO membrane water purification device, which includes an RO filter element 1, a frame 2, a clamping assembly 3 and a monitoring assembly 4. The RO filter element 1 has a relative liquid inlet and a liquid outlet. The clamping assembly 3 includes a bearing seat 31, which is arranged on the frame 2. The bearing seat 31 is provided with an embedding groove 32, and a positioning seat 33 is arranged in the embedding groove 32 to fix the RO filter element 1; two abutting seats 34 are arranged in the embedding groove 32, and the two abutting seats 34 are slidably arranged on both sides of the positioning seat 33 to clamp the RO filter element 1, one of the abutting seats 34 is provided with a liquid inlet pipe 35 to connect the liquid inlet; the other abutting seat 34 is provided with a liquid outlet pipe 36 to connect the liquid outlet; the monitoring assembly 4 includes a monitoring tube 41 and a connecting pipe 42, the connecting pipe 42 connects the embedding groove 32 and the monitoring tube 41, and a liquid level alarm 43 is arranged in the monitoring tube 41.

[0039] After the RO filter element 1 is initially fixed by the positioning seat 33, the abutting seats 34 on both sides are moved, so that the two abutting seats 34 clamp the above-mentioned RO filter element 1, so that the RO filter element 1 maintains overall force stability, and the interfaces at both ends are not easy to loosen and deform, adapting to the bumpy environment of the ship and not prone to water leakage; in addition, a monitoring component 4 is also provided. If there is leakage at the interface, the leaked liquid can flow into the monitoring tube 41 through the connecting pipe 42, thereby triggering the liquid level alarm 43, and the liquid level alarm 43 sounds an alarm to remind personnel to conduct timely inspection and maintenance.

[0040] like Figure 1 and Figure 2 As shown, it can be understood that a plurality of bearing seats 31 can be provided, and each bearing seat 31 is provided with an RO filter element 1 to improve the filtering efficiency. In the current embodiment, a plurality of bearing seats 31 are arranged at intervals along the height direction to reduce the occupied area, and a downpipe 46 is provided on the monitoring cylinder 41, and the connecting pipes 42 are connected to the downpipe 46, so that the number of monitoring cylinders 41 can be reduced.

[0041] like Figure 6 and Figure 8 As shown, in some embodiments, the positioning seat 33 is provided with one of the positioning grooves 37 or the positioning protrusions 38, and the RO filter element 1 is provided with the other of the positioning grooves 37 or the positioning protrusions 38, and the positioning protrusions 38 can be inserted into the positioning grooves 37, thereby fixing the RO filter element 1 to the positioning seat 33, which can achieve quick insertion and positioning on the one hand, and also play a role of stability on the other hand. For example, in order to facilitate processing, the positioning seat 33 is provided with the positioning grooves 37, and the RO filter element 1 is provided with the positioning protrusions 38.

[0042] In some embodiments, each of the abutting seats 34 is provided with one of the fixing blocks 39 or the plug rod 310 on opposite sides, and the RO filter element 1 is provided with the other of the fixing blocks 39 or the plug rod 310 on opposite sides, and the fixing blocks 39 are provided with a plug hole opposite to the plug rod 310. When the abutting seat 34 moves toward the positioning seat 33, the plug rod 310 is plugged into the plug hole, thereby further fixing the RO filter element 1 from the side, further stabilizing the RO filter element 1, and avoiding looseness at the interface. Exemplarily, for the convenience of processing, the plug rod 310 is provided on the abutting seat 34, and the fixing block 39 is provided on the RO filter element 1.

[0043] like Figure 6 As shown, in some embodiments, in order to further stabilize the RO filter element 1, a slot 311 is provided on the side of the abutting seat 34 facing the positioning seat 33, so that when the abutting seat 34 clamps the RO filter element 1, the two ends of the RO filter element 1 are respectively clamped in the above-mentioned slot 311, and in order to facilitate the connection of the RO filter element 1, the liquid inlet pipe 35 and the liquid outlet pipe 36 both pass through the above-mentioned slot 311 to enable normal liquid inlet and outlet.

[0044] like Figures 4 to 6 As shown, in some embodiments, the clamping assembly 3 further includes a driving member 312, the output end of which is connected to the abutting seat 34, so as to drive the abutting seat 34 to move in the embedded groove 32. Further, the driving member 312 includes a screw rod 3121 extending along the length direction of the embedded groove 32, two screw rods 3121 are provided, and the two screw rods 3121 are spaced apart along the width direction of the embedded groove 32, and one end of the screw rod 3121 is transferred to the bearing seat 31. In this embodiment, the screw rod 3121 is transferred by a bearing provided on the bearing seat 31. The abutting seat 34 is screwed to the two screw rods 3121, so that by screwing the screw rods 3121, the abutting seat 34 can move in the embedded groove 32, thereby clamping the RO filter element 1. Further, in order to facilitate screwing, the end of at least one of the screw rods 3121 passes through the embedded groove 32, and the end of the screw rod 3121 passing through the embedded groove 32 is provided with a rotating handle 3122. It should be noted that, in the current embodiment, in order to facilitate the screwing, the synchronous rotation of the two screw rods 3121 is achieved through a rotating handle 3122, and a synchronization component is also provided in the embedded groove 32. The rotating handle 3122 and the two screw rods 3121 are connected through the synchronization component, and the rotation of the two screw rods 3121 can be synchronously controlled by the rotating handle 3122. Exemplarily, the synchronization component can adopt a synchronous belt or a synchronous wheel, which is a commonly used synchronization mechanism in the prior art and will not be described in detail. Of course, in another embodiment, the ends of the two screw rods 3121 both pass through the embedded groove 32, and a rotating handle 3122 is provided at the end of each screw rod 3121.

[0045] like Figure 7As shown, in some embodiments, a liquid accumulation groove 314 is provided at the bottom of the embedded groove 32 so that liquid can be collected through the liquid accumulation groove 314, and the connecting pipe 42 is connected to the liquid accumulation groove 314. In addition, since a small amount of liquid will inevitably flow out of the RO filter element 1 in the bumpy environment of the ship during installation and use, if the small amount of liquid enters the monitoring tube 41 and triggers the liquid level alarm 43, the liquid level alarm will sound an alarm, which can be called a false alarm phenomenon. Based on the above phenomenon, the height of the pipe mouth of the connecting pipe 42 located in the liquid accumulation groove 314 is higher than the bottom height of the liquid accumulation groove 314. That is, when a small amount of liquid enters the liquid accumulation groove 314, the liquid will not enter the connecting pipe 42, and only when the liquid reaches a certain height will it enter the monitoring tube 41, thereby avoiding the false alarm phenomenon. Specifically, in some embodiments, the connecting pipe 42 can be connected to the side wall of the liquid accumulation groove 314. In the current embodiment, in order to avoid unnecessary interference, a protruding water accumulation platform 313 is provided at the bottom of the liquid accumulation tank 314, and the pipe opening of the connecting pipe 42 located in the liquid accumulation tank 314 is located at the top of the water accumulation platform 313, that is, the connecting pipe 42 passes through the top of the above-mentioned water accumulation platform 313, so that the liquid will enter the monitoring tube 41 only when the accumulation height is higher than the above-mentioned water accumulation platform 313, and the liquid level is detected by the liquid level alarm 43. When the accumulated water level exceeds the set threshold, an on-site alarm or a network remote warning is provided, so as to quickly notify the on-site personnel to perform maintenance, thereby avoiding false alarms. Exemplarily, the liquid level alarm 43 adopts a liquid level detection alarm.

[0046] like Figure 3 As shown, in some embodiments, a spiral head 47 is fixed to one end of the liquid level alarm 43, and a threaded hole that cooperates with the spiral head 47 is opened on the top of the monitoring tube 41, so that the liquid level alarm 43 can be screwed onto the monitoring tube 41; in addition, a cable is arranged on the spiral head 47 to be able to power the liquid level alarm 43.

[0047] In some embodiments, a drain pipe 44 is connected to the monitoring cylinder 41, and a switch valve 45 is provided on the drain pipe 44, so that the liquid in the monitoring cylinder 41 can be discharged through the switch valve 45. Exemplarily, the switch valve 45 is a solenoid valve.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
