Недостатком данного судоподъемника вл етс низка экономичность.The disadvantage of this ship elevator is its low efficiency.

Целью изобретени вл етс повышение экономичности работы судоподъемника путем снижени т гового усили и мощности привода передвижного щита.The aim of the invention is to improve the efficiency of the ship elevator by reducing the tractive effort and drive power of the movable shield.

Поставленна цель достигаетс тем, что по обеим сторонам наклонного лотка в верхней его части выполнены сообщающиес с лотком компенсирующие емкости, стенки которых параллельны оси лотка и расположены по отнощению к стенкам лотка под углом ot, определ емым соотнощениемThe goal is achieved by the fact that, on both sides of the inclined tray in its upper part, compensating tanks communicating with the tray are made, the walls of which are parallel to the axis of the tray and are located relative to the walls of the tray at an angle ot determined by the ratio

Claims

The inclined tubeless lift consists of an inclined reinforced concrete chute 1, a movable shield 2 with a drive 3 and a half-open gate 4 in the upper reach, equipped with a gate 5. The movable shield 2 has an opening in the middle part, overlapped with a panel shutter 6. To prevent leakage, the movable shield has a seal 7 , sealing it along the bottom and walls of tray 1. In the upper part of the inclined tray 1, in the part on which the movable shield 2 does not go, compensating containers 8 and 9 communicating with the tray are open on the side of the tray, 10 and 11 are parallel to the tray axis and positioned with respect to the walls of the tray at an angle. . The wedge prism of water moved but inclined tray 1 by the movable shield 2 can be divided into two parts. One part — the non-working — the wedge prism vertex of the RC and the other part — is working, in the form of a trapezoid with bases t and 1 and useful length C ,, where t is the depth of the wedge; T - water depth in front of the shield. The useful depth of the working part of the prism is determined by the draft of the estimated vessel with the required depth of water under its bottom. When the water level in the wedge prism is equalized with the level of water in the upper reach, the wedge prism turns into trapezoidal (Fig. 3), and the useful length of the working prism is increased by a, and the water depth in front of the movable shield is correspondingly by aE. The increment of the useful length a of the working prism is determined from the equation a - L ± P7 + II where L EH + n is the total length of the wedge prism (Fig. 1). In this tray design (Fig. 2), the length of the working part of the prism and the depth of the water in front of the shield are useful when leveling the water in the clip prism with the water level in the upstream remain unchanged due to the non-working volume of water located in the wedge prism vertex in the side wedge cavities of the tray, formed by tilting its side walls to the outside. The volume of these lateral wedge cavities is equal to the volume of water outside the wedge prism. The volume of compensating tanks W, 2-0,5tE-tlg C t ttgoi The volume of the non-working part of the wedge prism W 0,5-FHt-B; but Wi W and EH it; whence 0.5-1 The operation of the inclined tubeless lift when transferring the vessel from the downstream to the upper one is carried out as follows. The movable shield is set so that the calculated level in tray 1 behind the movable shield 2 coincides with the water level in the downstream, while the valve is open (lowered to the lower position). The vessel enters tray 1 and the valve is lifted, closing the opening in the mobile panel

2. At the same time, the vessel is moored to the mobile shield. Then, using the drive 3, the movable shield is moved to the half-bed 4 of the upstream. After the vertex clornor of the prism touches gate 5 of the half-gate 4, the wedge prism (if viewed in longitudinal section along the axis of the tray), begins to transform into a trapezoidal one. The water begins to fill the compensating tanks 8 and 9. As a result, over the entire period of the operation to level the water levels in the tray with the level of the veda in the upstream, the water depth T in front of the movable shield 2 does not change. After the water levels in the tray and in the headwater basin are equalized, the frontal shield 2 is stopped, the gate 5 of the half-gateway 4 is opened and the vessel from tray 1 leaves into the upper bay. The transfer of the vessel from the upstream to the downstream is carried out in reverse order. The invention makes it possible to reduce the hydrostatic load acting on the movable shield and, consequently, reduce the tractive force and drive power. Claims of the invention: Inclined tubeless ship lifting. Includes an inclined tray, the upper reach of which is made with a half-lock, as well as a movable shield mounted in the tray and equipped with a drive meter, characterized in that, in order to increase the efficiency of its operation by reducing the drag force and the power of the drive of the mobile board, on both sides of the inclined tray in its upper part, are made up of compensating tanks communicating with the tray, the walls of which are parallel to the axis of the tray and are located relative to the walls of the tray at an angle J, thinned emym relation tg 0,5 | -, where i - the slope of the tray; In - the width of the lot; E is the length of the sloping walls of the compensating tanks. at the same time, the angle of angle JL is located at the level of the bottom of the half-nozzle of the upstream.
