[0025] In order to better understand the technical scheme of the utility model, the utility model will be described in detail below in combination with the drawings.

[0026] In the embodiment 1 of the whistle pulling mechanism in the utility model,

[0027] The compass deck has an opening, the through-cabin piece is arranged at the opening of the compass deck and has a cable through hole for the cable to pass through, and a rain cover for protecting the through-cabin piece is further arranged, the rain cover divides the cable into two parts, and the two parts of the cable are connected with the rain cover respectively, so that the through-cabin piece can be covered and the whistle can be controlled at the same time.

[0028] As Figure 1 and Figure 2As shown, the whistle pulling mechanism in this embodiment includes a through-passage member 3 arranged on the binnacle deck 1, which is a cylindrical elongated metal cylinder, and a through-hole for a pulling rope is formed in the cylindrical structure of the through-passage member 3. In order to realize the fixed connection of the through-passage member 3 and the binnacle deck 1, a transition plate 2 is further arranged between the through-passage member 3 and the binnacle deck 1, which is a round plate, and a mounting hole matching the outer peripheral surface of the through-passage member 3 is arranged at the center of the transition plate 2. The size of the transition plate 2 is larger than the opening on the binnacle deck 1, and the lower plate surface of the transition plate 2 is welded and fixed with the upper surface of the binnacle deck 1 when connected, and the outer peripheral surface of the through-passage member 3 is welded and fixed with the mounting hole at the center of the transition plate 2, and the welding at the two places is full circumference welding, which can realize fixed connection and also seal and prevent water, that is, even if there is some rainwater on the upper surface of the binnacle deck 1, it will not enter the cabin interior through the gaps between the binnacle deck 1 and the transition plate 2 and the transition plate 2 and the through-passage member 3. At the same time, the arrangement of the transition plate 2 can also strengthen the structure of the opening of the binnacle deck 1. Of course, in other embodiments, the transition plate can not be arranged, and an opening matching the size of the through-passage member can be directly arranged on the binnacle deck.

[0029] As shown in Figure 1 , Figure 3 and Figure 4 , the arrangement of the through-passage member 3 facilitates the passing of the pulling rope, and also forms a leakage point where water leakage may occur in rainy weather. The whistle pulling mechanism in this embodiment further includes a rain cover 4. The rain cover 4 includes a rainproof cylinder 41 and a rain cover plate 42 welded at the end of the rainproof cylinder 41. The rainproof cylinder 41 is a hollow cylindrical structure, and the inner diameter of the rainproof cylinder 41 is larger than the outer diameter of the through-passage member 3, that is, the rainproof cylinder 41 can be sleeved on the outer periphery of the through-passage member 3 and match the through-passage member 3 with a gap. In addition, the length of the rainproof cylinder 41 is greater than the length of the through-passage member 3 above the transition plate 2, so that the rain cover 4 can be placed on the binnacle deck 1. The rain cover plate 42 is welded on the upward end surface of the rainproof cylinder 41, so as to shield the rainproof cylinder 41 and prevent rainwater from entering through the central hole of the rainproof cylinder 41. The rainproof cylinder 41 and the rain cover plate 42 are connected by full circumference welding, which can realize fixed connection and also realize sealing to prevent rainwater from seeping in. Alternatively, in other embodiments, the length of the rainproof cylinder can be set to be smaller than the length of the through-passage member above the transition plate, at which time the rainproof cylinder will not contact the binnacle deck. Of course, in other embodiments, the rain cover plate can be adhered to the end surface of the rainproof cylinder. Alternatively, in other embodiments, the rainproof cylinder and the through-passage member can contact, at which time lubricating oil should be arranged between the rainproof cylinder and the through-passage member to ensure small frictional resistance.

[0030] In order to facilitate the control of the siren by the cable, the cable is divided into two parts, and is separated at the rainproof cover plate 42. An upper pull ring 43 is welded on the upper side of the rainproof cover plate 42, and a lower pull ring 44 is arranged on the lower side of the rainproof cover plate 42. The upper pull ring 43 and the lower pull ring 44 are both in U shape, and specifically, the upper pull ring 43 and the lower pull ring 44 are both in semicircular shape. The end of the opening end of the upper pull ring 43 and the lower pull ring 44 is welded on the rainproof cover plate 42. The plane where the ring body of the upper pull ring 43 is located is perpendicular to the plane where the ring body of the lower pull ring 44, that is, the upper pull ring 43 and the lower pull ring 44 are staggered. The upper cable is fixedly connected to the upper pull ring 43, and the lower cable is fixedly connected to the lower pull ring 44.

[0031] The rain cover 4 is not fixedly connected to the cabin-penetrating part 3, and the position of the rain cover 4 is limited by the pulling force provided by the upper cable. One end of the upper cable is connected to the siren, and the other end is connected to the rain cover 4. The rain cover 4 is kept in the corresponding position and suspended by the pulling force of the upper cable. When the siren needs to emit a sound signal, the lower cable is pulled. At this time, the rain cover 4 is driven downward by the lower cable, and the upper cable is also driven downward to pull the siren. When the pulling is finished, the reaction force provided by the siren will pull the rain cover 4 upward. In order to realize the automatic reset of the siren, the weight of the rain cover 4 cannot be too large, and the friction resistance between the rain cover 4 and the cabin-penetrating part 3 should be small. Therefore, the rain cover 41 is gap-fitted with the cabin-penetrating part 3, so as to reduce or even eliminate the friction resistance in the recovery process of the siren. On the other hand, in order to ensure that the rain cover 4 has a small weight, the thickness of the rain cover 4 itself is relatively small. If the upper pull ring 43 and the lower pull ring 44 are welded at the same position, the rain cover plate 42 may be welded through. In the embodiment, the upper pull ring 43 and the lower pull ring 44 are staggered, thereby reducing the risk of the rain cover plate 42 being welded through and ensuring the good shielding effect.

[0032] In addition, the rain cover plate 42 has an outer edge protruding from the rain cover 41. In use, rainwater can be prevented from entering the contact part of the rain cover plate 42 and the rain cover 41 along the edge of the rain cover plate 42 as much as possible, thereby further reducing the risk of water leakage. Of course, in other embodiments, the rain cover plate can also be flush with the edge of the rain cover.

[0033] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
