Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a transmission device for remotely controlling a valve. Background Art

[0002] There are many valves inside the ship, especially the ballast valve at the bottom of the bilge, which automatically discharges the ballast water from the bottom of the bilge to the outside of the bilge when it is opened. At the same time, the seawater outside the bilge cannot flow back into the bilge under the action of the check valve, so that the ballast valve is closed and the cabin is sealed without leakage. However, the opening and closing of the ballast valve requires manual operation, which is inconvenient to operate, and it takes a long time for the operator to move from the deck or the cabin to the ballast valve at the bottom of the bilge to operate it. Therefore, a transmission device for remotely controlling the valve is urgently needed to solve the above problems. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0021] A transmission device for remotely controlling a valve, combined with Figure 1 , Figure 2 and Figure 3As shown, it acts on the ballast valve 1, including: a valve seat shutter 2, a first universal bearing 3, a universal shaft 4, a second universal bearing 5 and a transmission shaft 6; the valve seat shutter 2 drives the ballast valve 1 to rotate; the universal shaft 4 includes a first universal shaft 41 and a second universal shaft 42, the first universal shaft 41 drives the valve seat shutter 2 through the first universal bearing 3, and the transmission shaft 6 drives the second universal shaft 42 through the second universal bearing 5, and the first universal shaft 41 and the second universal shaft 42 are connected by a profile. The transmission shaft 6 is rotated, and the transmission shaft 6 drives the second universal shaft 42 to rotate through the second universal bearing 5. The second universal shaft 42 drives the first universal shaft 41 to rotate through the profile connection, and the first universal shaft 41 then drives the valve seat shutter 2 to rotate through the first universal bearing 3. The valve seat shutter 2 drives the ballast valve 1 to rotate, thereby closing or releasing the ballast valve 1. The first cardan shaft 41 and the second cardan shaft 42 can be extended and retracted in the axial direction by the profile connection, so as to make up for the distance of the valve disc of the ballast valve 1 falling and absorb the distance of the valve disc of the ballast valve 1 rising. Therefore, the device can realize the remote control of the ballast valve 1.

[0022] Preferably, the first cardan shaft 41 and the second cardan shaft 42 are connected by a spline. The spline connection can improve the force between the first cardan shaft 41 and the second cardan shaft 42, ensuring that the first cardan shaft 41 and the second cardan shaft 42 rotate synchronously while allowing the first cardan shaft 41 and the second cardan shaft 42 to slide smoothly along the axial direction.

[0023] Preferably, the valve seat shutter 2 is detachably connected to the ballast valve 1, so that the valve seat shutter 2 can be easily removed for maintenance; and when in the bilge, the valve disc of the ballast valve 1 can be easily operated after the valve seat shutter 2 is removed.

[0024] Specifically, the valve seat shutter 2 includes a plurality of pins, which are locked by nuts after passing through the valve disc of the ballast valve 1. When the valve seat shutter 2 rotates, the plurality of pins push the valve disc to rotate.

[0025] Preferably, it further comprises a fixed sleeve 7, with bushings 8 at both ends of the sleeve 7, and the transmission shaft 6 passes through the bushing 8 at one end of the sleeve 7 and passes through the bushing 8 at the other end. The sleeve 7 can be fixed on the operating table on the deck, and the bushings 8 at both ends of the sleeve 7 ensure that the transmission shaft 6 rotates smoothly, and the sleeve 7 limits the position of the axis of the transmission shaft 6.

[0026] Preferably, an annular groove is formed on the transmission shaft 6, and a snap ring 9 is clamped in the annular groove. The snap ring 9 is located at the end of the sleeve 7 away from the second universal bearing 5 and abuts against the end surface of the bushing 8. The snap ring 9 abuts against the end surface of the bushing 8 to prevent the transmission shaft 6 from falling.

[0027] Preferably, a retaining ring 10 and a self-locking nut 20 are sleeved on the transmission shaft 6, and the retaining ring 10 is located at one end of the sleeve 7 facing the second universal bearing 5; the self-locking nut 20 presses the retaining ring 10 and locks it on the end face of the bushing 8. When the retaining ring 10 is pressed on the end face of the bushing 8 by the self-locking nut 20, the clamping ring 9 and the retaining ring 10 clamp the sleeve 7 from the upper and lower ends to prevent the transmission shaft 6 from moving in the axial direction.

[0028] Preferably, a sealing ring is provided on the inner ring of the bushing 8 to ensure that the transmission shaft 6 can achieve good watertightness after entering the cabin and meet the sealing requirements.

[0029] Preferably, a square column is provided at one end of the transmission shaft 6 away from the second universal bearing 5, and the square column is used to cooperate with a ratchet wrench. Compared with installing a handwheel, rotating the transmission shaft 6 by using a ratchet wrench can increase the operating speed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
