在本新型被詳細描述之前,要注意的是,在以下的說明內容中,類似的元件是以相同的編號來表示。 Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖2,本發明漂浮式監測裝置2之第一較佳實施例包含一可漂浮於海面200上的浮標21、一用以錨碇該浮標21的錨碇單元22,及一監測單元23。 Referring to Figure 2, a first preferred embodiment of the floating monitoring device 2 of the present invention includes a buoy 21 that floats on the surface 200, an anchor unit 22 for anchoring the buoy 21, and a monitoring unit 23.
該浮標21包括一能漂浮於海面200上的浮體211、一設置於該浮體211且位於海面200下的金屬架體212,及一安裝於該金屬架體212遠離該浮體211之一側的配重件213。於本較佳實施例中,該金屬架體212是概呈倒三角狀,而該配重件213安裝於概呈倒三角狀之金屬架體212的尖端處,以調整該浮體211的重心使該浮體211保持平衡。 The buoy 21 includes a floating body 211 floating on the sea surface 200, a metal frame 212 disposed on the floating body 211 and located under the sea surface 200, and a metal frame 212 mounted on the metal frame 212 away from the floating body 211. Side weight member 213. In the preferred embodiment, the metal frame 212 is substantially inverted triangle, and the weight member 213 is mounted at the tip end of the generally inverted triangular metal frame 212 to adjust the center of gravity of the floating body 211. The float 211 is kept in balance.
該錨碇單元22包括一連接該浮標21之金屬架體212的連接索221、一與該連接索221相間隔且錨碇於海床201的錨碇索222,及一樞轉地連接該連接索221與該錨碇索222的樞轉件223。 The anchor unit 22 includes a connecting cable 221 connecting the metal frame 212 of the buoy 21, an anchor cable 222 spaced from the connecting cable 221 and anchored to the seabed 201, and pivotally connecting the connecting cable The cable 221 and the pivoting member 223 of the anchor cable 222.
該連接索221、錨碇索222與該樞轉件223皆是金屬材質,且該錨碇索222的長度遠大於該連接索221的長度。於本較佳實施例中,該錨碇索222是500公尺長,而該連接索221是1公尺長。 The connecting cable 221, the anchoring cable 222 and the pivoting member 223 are both made of metal, and the length of the anchoring cable 222 is much larger than the length of the connecting cable 221. In the preferred embodiment, the anchor cable 222 is 500 meters long and the connecting cable 221 is 1 meter long.
該樞轉件223具有一連接該連接索221的第一套環部224、一連接該錨碇索222的第二套環部225,及一連接該第一套環部224與該第二套環部225的套筒部226,該第一套環部224與該第二套環部225能分別相對該套筒部226樞轉。 The pivoting member 223 has a first collar portion 224 connecting the connecting cable 221, a second collar portion 225 connecting the anchor cable 222, and a first sleeve portion 224 and the second sleeve. The sleeve portion 226 of the ring portion 225, the first collar portion 224 and the second collar portion 225 are pivotable relative to the sleeve portion 226, respectively.
該監測單元23包括數個間隔設置於該錨碇索222上的感測器231、一設置該浮標21之浮體211相反於該金屬架體212之一側上的接收器232,及一與所述感測器231對應設置於該連接索221上且耦接所述感測器231與該接收器232的資料傳輸機構235。 The monitoring unit 23 includes a plurality of sensors 231 disposed on the anchor cable 222, a receiver 232 disposed on a side of the metal frame 212 opposite to the floating body 211, and a The sensor 231 is correspondingly disposed on the connecting cable 221 and coupled to the data transmission mechanism 235 of the sensor 231 and the receiver 232.
該接收器232具有一設置於該浮體211上的防水艙體233,及一設置於該防水艙體233中的資料接收元件234。於本較佳實施例中,該資料接收元件234是能儲存資料的電路板。 The receiver 232 has a waterproof compartment 233 disposed on the floating body 211, and a data receiving component 234 disposed in the waterproof compartment 233. In the preferred embodiment, the data receiving component 234 is a circuit board capable of storing data.
該資料傳輸機構235具有一與該資料接收元件234電連接的接頭236、一設置於該錨碇索222上且與所述感測器231耦接的感應器237、一連接該接頭236與該感應器237的電纜238、一將該電纜238定位於該浮標21之浮體211上的第一夾具239,及一將該感應器237定位於該錨碇索222上的第二夾具230。 The data transmission mechanism 235 has a connector 236 electrically connected to the data receiving component 234, a sensor 237 disposed on the anchor cable 222 and coupled to the sensor 231, and a connector 236 connected thereto. A cable 238 of the inductor 237, a first clamp 239 for positioning the cable 238 on the floating body 211 of the buoy 21, and a second clamp 230 for positioning the inductor 237 on the anchor cable 222.
由於該連接索221、錨碇索222與該樞轉件223皆是金屬材質,因此,該感應器237可以利用該連接索221、錨碇索222與該樞轉件223作為導體,以接收所述感測器231所測得的資訊。 Since the connecting cable 221, the anchor cable 222 and the pivoting member 223 are both made of metal, the inductor 237 can utilize the connecting cable 221, the anchor cable 222 and the pivoting member 223 as conductors to receive the receiving device. The information measured by the sensor 231 is described.
再者,由於該第一套環部224與該第二套環部225能相對該套筒部226樞轉,且該第一套環部224與該第二套環部225是分別連接該連接索221與該錨碇索222,因此,受到風力或海流作用時,該連接索221與該錨碇索222能各自隨海流與風向轉動而不會相互干涉。 Furthermore, since the first collar portion 224 and the second collar portion 225 can pivot relative to the sleeve portion 226, the first collar portion 224 and the second collar portion 225 are respectively connected to the connection. The cable 221 and the anchor cable 222, therefore, when subjected to wind or current, the connecting cable 221 and the anchor cable 222 can each rotate with the sea current and the wind direction without interfering with each other.
而且由於該連接索221的長度遠小於該錨碇索222的長度,因此,將該資料傳輸機構235設置於該連接索221上,配合該第一夾具239與該第二夾具230分別定位該電纜238與該感應器237,不但能使該浮標21、資料傳輸機構235與該連接索221一同轉動,以有效避免該連接索221與該資料傳輸機構235的電纜238互相纏繞糾結而發生損壞,以提高穩定性與使用壽命,還能有效降低維修成本。 Moreover, since the length of the connecting cable 221 is much smaller than the length of the anchor cable 222, the data transmission mechanism 235 is disposed on the connecting cable 221, and the first clamp 239 and the second clamp 230 are respectively positioned to the cable. 238 and the sensor 237, not only can the buoy 21 and the data transmission mechanism 235 rotate together with the connecting cable 221, so as to effectively prevent the cable 238 and the cable 238 of the data transmission mechanism 235 from being entangled with each other and damaged. Improve stability and service life, and reduce maintenance costs.
參閱圖3,本發明漂浮式監測裝置2的第二較佳實施例大致是與該第一較佳實施例相似,不相同的地方在於:錨碇索222具有一連接該樞轉件223之第二套環部225且以導體所製成的感應段227,及一連接該感應段227且錨碇與海床201並以非導體所製成的錨碇段228,所述感測器231是設置於該感應段227,而該感應段227的長度大於該連接索221的長度。於本較佳實施例中,該感應段227是以金屬所製成,而該錨碇段228是以尼龍(Nylon)材質製成。 Referring to FIG. 3, a second preferred embodiment of the floating monitoring device 2 of the present invention is substantially similar to the first preferred embodiment. The difference is that the anchor cable 222 has a connection to the pivoting member 223. Two sets of ring portions 225 and a sensing section 227 made of a conductor, and an anchoring section 228 connecting the sensing section 227 and anchoring the seabed 201 and being made of a non-conductor, the sensor 231 is The sensing segment 227 is disposed, and the length of the sensing segment 227 is greater than the length of the connecting cable 221. In the preferred embodiment, the sensing section 227 is made of metal, and the anchor section 228 is made of nylon (Nylon) material.
由於本較佳實施例大致是與該第一較佳實施例相似,因此除了可以達成與該第一較佳實施例相同的功效外,兩段式的錨碇索222除可適應不同水深外,還可以有效降低成本。 Since the preferred embodiment is substantially similar to the first preferred embodiment, the two-stage anchor chord 222 can be adapted to different water depths, except that the same effect as the first preferred embodiment can be achieved. It can also effectively reduce costs.
綜上所述,本發明漂浮式監測裝置2利用樞轉地連接該連接索221與該錨碇索222的樞轉件223,使該連接索221與該錨碇索222能各自隨海流與風向位移,配合將該資料傳輸機構235設置於該連接索221上,不但能隨該連接索221位移,也能避免該連接索221與該資料傳輸機構235 互相纏繞糾結,以提高穩定性與使用壽命,還能有效降低維修成本,故確實能達成本發明之目的。 In summary, the floating monitoring device 2 of the present invention pivotally connects the connecting cable 221 and the pivoting member 223 of the anchor cable 222, so that the connecting cable 221 and the anchor cable 222 can respectively follow the current and the wind direction. Displacement and cooperation of the data transmission mechanism 235 on the connecting cable 221 can not only displace the connecting cable 221, but also avoid the connecting cable 221 and the data transmission mechanism 235. The purpose of the present invention is achieved by intertwining and tangling to improve stability and service life, and to effectively reduce maintenance costs.
惟以上所述者,僅為本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。 The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
