Description

可提升傳動效率的水上踩踏推進裝置 Water pedaling propulsion device capable of improving transmission efficiency

本發明係有關於一種可以使踩踏動作更為省力，以及動力輸出更具有效率之水上踩踏推進裝置。 The present invention relates to a water pedaling propulsion device that can make pedaling actions more labor-saving and have more efficient power output.

由於台灣擁有四面環海的美好條件，促使近年來許多的海上休閒器具日益盛行，使得海上活動蓬勃發展。如今海上休閒可選擇的類型更是多樣，例如：天鵝船、香蕉船、風浪板等。台灣的各縣市都有適合水上休閒活動的地方，即使是在不靠海的南投，也有寬廣美麗的日月潭。因此水上休閒活動為少數不受地理位置限制又可放鬆身心的休閒娛樂。雖然現今的休閒活動及設施越來越多，然而因為價格上的考量，以及使用時間上的侷限，因而造成許多限制，而無法大量的普及化。 Due to Taiwan's beautiful conditions surrounded by the sea, many marine leisure appliances have become increasingly popular in recent years, and marine activities have flourished. Nowadays, the types of marine leisure options are more diverse, such as: swan boat, banana boat, windsurfing board, etc. All counties and cities in Taiwan have places suitable for water leisure activities. Even in Nantou, which is not close to the sea, there is also a wide and beautiful Sun Moon Lake. Therefore, water leisure activities are one of the few leisure entertainments that can relax without being restricted by geographical location. Although there are more and more leisure activities and facilities nowadays, due to price considerations and limited use time, many restrictions have been imposed, and they cannot be widely popularized.

例如有中華民國88年8月1日所公告之新型第365959號「水上人力驅動休閒船」專利案，其係揭露：係由一船身以及設於船身內部之驅動機構、轉向機構所構成，其中船身之後端設一管件凸露於船身底部，驅動機構係由鍊輪、變速箱及一由變速箱將動力延伸至上述管件內部之螺旋漿所組成，鍊輪之中心兩側設有踏板，俟使用者以人力踩動踏板令鍊輪轉動後，經由變速箱轉換成高轉速之動力，令螺旋漿高轉速旋轉，使水流自管件噴出，進而推動船身前推，屆時，以轉向機構控制船身前進之方向，此種休閒船不但不會濺起水花，又能較為高速地行駛，具有休閒趣味性，亦可兼得運動之效果。 For example, there is a new type patent case No. 365959 "Marine human-powered recreational boat" announced on August 1, 88 of the Republic of China, which discloses that it is composed of a hull, a driving mechanism and a steering mechanism installed inside the hull , The rear end of the hull is provided with a pipe protruding from the bottom of the hull. The drive mechanism is composed of a sprocket, a gearbox and a propeller that extends the power to the inside of the pipe by the gearbox. Both sides of the center of the sprocket There are pedals. After the user steps on the pedals to rotate the sprocket, it is converted into high-speed power through the gearbox, which makes the propeller rotate at high speed, so that the water jets out of the pipe fittings, and then pushes the hull forward. The steering mechanism controls the forward direction of the hull. This kind of leisure boat not only does not splash, but also can travel at a relatively high speed, which is leisurely and interesting, and can also have the effect of sports.

該專利前案係利用人力方式進行踩踏以供前進，惟其踩踏後所產生之動能，經由驅動機構之傳動後，則會造成能量耗損，再加上水中的阻力，踩踏時不僅耗力，而且所能帶動船身前進的動能已變的相當小，因此前進之速度相當慢，而不符使用效益。尤其雙腳踩踏的方式需要踩踏一整圈後才能完成一個行程，不僅費力，而且需要有較大之圓形踩踏空間，造成船體的體積過大，無法縮小體積。 The previous case of the patent uses manual pedaling for advancement, but the kinetic energy generated after pedaling is transmitted by the driving mechanism, which will cause energy loss. In addition to the resistance in the water, the pedaling is not only labor-intensive, but also The kinetic energy that can drive the hull forward has become quite small, so the forward speed is quite slow, which is not in line with the efficiency of use. In particular, the two-foot pedaling method needs to pedal a full circle to complete a stroke, which is not only laborious, but also requires a larger circular pedaling space, which causes the hull of the ship to be too large and unable to reduce the volume.

又有如中華民國105年1月11日所公告之發明第I516414號「水上跑步動力船」專利案，其係揭露：一方向控制機構係樞設於一板體，該方向控制機構自該板體之上側朝上延伸之一端設有一握持部且其自該板體之下側朝下延伸之一端設有一方向調整部，一驅動機構設於該板體且包括一跑踩單元及一推進單元，該跑踩單元可轉動地設於該板體上側，該推進單元與該跑踩單元成轉動連接關係且朝下延伸至該板體下側下方之一端設有一推進組件，該跑踩單元可轉動而帶動該推進組件旋轉以產生一推進動力。藉此，可同時具有多重運動模式及休閒娛樂功效，亦可調整所需跑踩速度，甚至可獲得所有使用相關資訊。 Another example is the Invention No. I516414 "Water Running Power Boat" patent case announced by the Republic of China on January 11, 105, which discloses: a direction control mechanism is pivoted to a plate body, and the direction control mechanism is from the plate body. One end extending upward from the upper side is provided with a gripping portion and one end extending downward from the lower side of the board is provided with a direction adjusting portion, a driving mechanism is provided on the board and includes a running unit and a propulsion unit , The running and stepping unit is rotatably arranged on the upper side of the board, the propulsion unit is in a rotationally connected relationship with the running and stepping unit and extends downward to one end of the lower side of the board. A propulsion assembly is provided. The rotation drives the propulsion assembly to rotate to generate a propulsion power. In this way, it can have multiple sports modes and leisure and entertainment functions at the same time, can also adjust the required running speed, and even obtain all use-related information.

該專利前案係利用跑步方式，以透過驅動機構板體前進，惟該驅動機構同樣具有能量耗損之缺點，而且跑步方式相當耗費體力，因此在使用上並不盡理想。 The previous case of the patent uses a running method to advance through the plate of the driving mechanism, but the driving mechanism also has the disadvantage of energy consumption, and the running method is quite physical, so it is not ideal in use.

Then step on the first pedal 311 and the second pedal 321 in turn. As shown in the third and seventh figures, when one of the feet steps on the first pedal 311, the first pedal 311 will drive the first input of the first link group 33 during the movement.

又本發明經由實際的測試，首先考量船體的浮力，並以下列計算式子表示。 In addition, the present invention firstly considers the buoyancy of the hull through actual tests, and expresses it in the following formula.

W_body≦W_buoy (1) W _body ≦W _buoy (1)

W_body=W_deck+W_thrust+W_passenger (2) W _body =W _deck +W _thrust +W _passenger (2)

W_buoy=V_underwater×ρ_water×g_gravity (3) W _buoy =V _underwater ×ρ _water ×g _gravity (3)

式子(1)中，W_body表示整艘船及其乘員的重量，W_buoy表示由船體吃水所產生的浮力。很明顯的W_buoy必須大於或等於W_body，才能使整艘船及其乘員能浮在水面上。 In formula (1), W _body represents the weight of the entire ship and its occupants, and W _buoy represents the buoyancy generated by the draught of the hull. Obviously, W _buoy must be greater than or equal to W _body to enable the entire ship and its crew to float on the water.

式子(2)中，定義一整艘船的重量W_body，為船體的組合單元甲板W_deck和組合單元推進裝置W_thrust以及乘員W_passenger之和。 In formula (2), define the weight of a whole ship, W _body , which is the sum of the combined unit deck W _deck of the hull, the combined unit propulsion device W _thrust and the crew W _passenger .

式子(3)中，由阿基米得原理可計算出船體的浮力W_buoy，此式中V_underwater表示船體排出的水之體積，ρ_water為水的密度，ρ_water

1(g/cm³)，g_gravity為重力加速度，g_gravity=9.8(m/s²)。考量W_deck=10(kgw)，W_thrust=30(kgw)，所以W_body=10+30+W_passenger=(40+W_passenger)(kgw)，故可計算出V_underwater與W_body的關係。 _{In formula (3), the buoyancy W buoy} of the hull can be calculated by Archimedes’ principle, where V _underwater represents the volume of water discharged from the hull, ρ _water is the density of water, ρ _water

1(g/cm ³ ), g _gravity is the acceleration of gravity, g _gravity =9.8(m/s ² ). Considering W _deck =10(kgw) and W _thrust =30(kgw), so W _body =10+30+W _passenger =(40+W _passenger )(kgw), so the relationship between _{V underwater} and W _{body can be calculated.}

W_body

W_buoy；(40+W_passenger)×10³(gw)

V_underwater(cm³)×1(g/cm³)×g_gravity；V_underwater(cm³)

(40+W_passenger)×10³(cm³)。 W _body

W _buoy ；(40+W _passenger )×10 ³ (gw)

V _underwater (cm ³ )×1(g/cm ³ )×g _gravity ；V _underwater (cm ³ )

(40+W _passenger )×10 ³ (cm ³ ).

因此測試時係採用兩個大小不等的大貨車內胎(truck tube)，大內胎外徑100(cm)，充氣圈截面直徑25(cm)，小內胎外徑為90(cm)，充氣圈截面直徑20(cm)，藉以提供船體浮在水面上的浮力，故可得到船體的吃水深度(cm)與船體重量W_body(kgw)，亦即乘員重量W_passenger(kgw)之關係圖，如第九圖所示。由第九圖可知，考量一位重量70(kgw)的乘員，船體的吃水深度約為13.6(cm)，亦即大約內胎高度的55%的吃水深度，此吃水深度可提供船體相當穩定的乘載。此外，船體的人員乘載重量的上限約為160(kgw)，故可輕易地提供雙人乘載。 Therefore, two large truck tubes of different sizes are used in the test. The outer diameter of the large inner tube is 100 (cm), the cross-sectional diameter of the inflatable ring is 25 (cm), and the outer diameter of the small inner tube is 90 (cm). Diameter 20 (cm), in order to provide the buoyancy of the hull floating on the water, so the draft of the hull (cm) and the hull weight W _body (kgw) can be obtained, that is, the passenger weight W _passenger (kgw) , As shown in the ninth figure. It can be seen from the ninth figure that considering an occupant weighing 70 (kgw), the draft of the hull is about 13.6 (cm), which is about 55% of the height of the inner tube, and this draft can provide a fairly stable hull The ride. In addition, the upper limit of the load capacity of the hull is about 160 (kgw), so it can be easily provided for two people.

又對於推進效率之考量，可以經由以下的式子來表示：

In addition, the consideration of propulsion efficiency can be expressed by the following formula:

η=η(η_ω，η_r) (5) η=η(η _ω ，η _r ) (5)

式子(4)中的η為航行阻力係數，可簡化此航行阻力係數η為η_ω推進系統效率係數及η_r波浪水阻係數的乘積η=η_ω×η_r。 In equation (4), η is the sailing resistance coefficient, which can be simplified as the product of η _ω propulsion system efficiency coefficient and η _r wave water resistance coefficient η=η _ω ×η _r .

η_ω和η_r可以以下列的形式來表示：η_ω=ρ_ω×ω_rotation ^α；η_r=ρ_r×v_boat ^β；所以式(4)變成如下之式子：

η _ω and η _r can be expressed in the following form: η _ω =ρ _ω ×ω _rotation ^α ; η _r =ρ _r ×v _boat ^β ; So the formula (4) becomes the following formula:

取ρ_ω=0.4，ρ_r=0.2，則(α，β)=(0.1，1.0)，(α，β)=(0.1，1.5)，(α，β)=(0.1，2.0)下的v_boat(m/s)與ω_rotation(2π×rpm)之關係，如第十圖所示，若採取(α，β)=(0.1，1.0)，而踩踏的速率為每分鐘左右腳各100次，則船體約可以以50(m/min)的速度在水面上航行。 Take ρ _ω = 0.4, ρ _r = 0.2, then (α, β) = (0.1, 1.0), (α, β) = (0.1, 1.5), v under (α, β) = (0.1, 2.0) _{The relationship between boat} (m/s) and ω _rotation (2π×rpm), as shown in the tenth figure, if (α, β) = (0.1, 1.0) is adopted, and the pedaling rate is 100 times per minute. , The hull can sail on the water at a speed of about 50 (m/min).

經由上述實際的測試，係足以證明本發明之水上踩踏裝置確實可據以實現，並達到以上所述之功效。 Through the above-mentioned actual test, it is sufficient to prove that the water pedaling device of the present invention can be realized and achieve the above-mentioned effects.
