Description

[0002] In municipal engineering, water conservancy gates are hydraulic structures built on rivers and canals to control flow and adjust water levels. Closing the gates can block floods, tides or raise upstream water levels. Opening the gates can discharge floods, waterlogging or wastewater, and can also supply water to downstream rivers or channels. Water gates are widely used in water conservancy projects and are mostly built in rivers, canals, reservoirs, lakes and coastal areas. my country's riverside and coastal areas are rich in tidal resources, which contain huge energy and high-quality water sources. Tidal power generation can be used to change the local energy structure; tidal differences can be used to divert clean water and improve the local water environment.

[0003] The existing gates can basically meet the needs of use, but there are still certain defects: when the river water and sea water are affected by wind, upstream rapids and other factors and the tides rise and fall, there is a lack of corresponding structure, and it is difficult to freely adjust the water replenishment on both sides of the gate plate according to the tides. It is easy to cause a sudden change in the liquid level on both sides of the gate, and it is impossible to fully utilize the tidal resources. In addition, it is impossible to keep the river water and sea water on both sides of the gate plate at the same height. Once large-scale flood discharge cannot be carried out in time, it is easy to cause economic losses.

[0004] Based on this, it is urgent to design a tidal-regulated water replenishment gate so that adjustable water replenishment can be performed on both sides of the gate plate according to the tidal rise and fall. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] like Figure 1-3As shown, in the municipal water replenishment and drainage project, in order to slowly and adjustable water replenishment or drainage on both sides of the gate plate according to the tidal fluctuations at different liquid levels, the utility model provides a tidal adjustment type water replenishment gate, including a gate plate 1, the lower wall of the gate plate 1 is provided with a water replenishment port 1 2 and a water replenishment port 2 3, one side of the gate plate 1 is provided with a baffle plate 1 4 arranged on the outside of the water replenishment port 1 2, the other side of the gate plate 1 is provided with a baffle plate 2 5 arranged on the outside of the water replenishment port 2 3, both side walls of the gate plate 1 are respectively provided with hollow rods 7 symmetrically arranged on the outside of the four corners of the water replenishment port 1 2 and the water replenishment port 2 3, a slide plate 8 is slidably connected in the hollow rod 7, a side wall of the slide plate 8 is provided with a support rod 9 passing through the hollow rod 7, the gate plate 1 and fixedly connected to the inner wall of the baffle plate 1 4 and the baffle plate 2 5, a reset spring 6 is provided between the inner bottom wall of the hollow rod 7 and the other side wall of the slide plate 8, and the cross-sectional areas of the baffle plate 1 4 and the baffle plate 2 5 are respectively larger than the cross-sectional areas of the water replenishment port 1 2 and the water replenishment port 2 3.

[0026] It can be seen that the gate plate 1 can realize the function of flood discharge or water replenishment of river water and sea water through the external lifting structure. In normal state, when the river water and sea water appear high tide and low tide, the river water and sea water on the high tide side of the gate plate 1 impact the shield plate 1 4 and the shield plate 2 5, thereby driving the shield plate 1 4 and the shield plate 2 5 to move away from the gate plate 1, thereby driving the support rod 9 and the slide plate 8 to move away from the gate plate 1, thereby making the reset spring 6 stressed in a stretched state. At this time, the river water and sea water on the high tide side of the gate plate 1 replenish water to the other side.

[0027] like Figure 1 , 2 As shown, the number of hollow rods 7 and supporting rods 9 are both eight, and the water replenishment port 1 2 and the water replenishment port 2 3 arranged at the lower part of the gate are symmetrically arranged on the left and right. The water replenishment port 1 2 and the water replenishment port 2 3 can be rectangular through holes, and the hollow rod 7 is fixedly arranged on the side wall of the gate plate 1 away from the baffle plate 1 4 and the baffle plate 2 5, so that the baffle plate 1 4 and the baffle plate 2 5 can completely cover the water replenishment port 1 2 and the water replenishment port 2 3 in the initial state, so as to replenish the river water and sea water on both sides of the gate according to the tidal rise and fall.

[0028] like Figure 3 As shown, the water replenishment gate of the present invention is a gate for tidal bidirectional regulation of water replenishment or drainage based on the water level pressure difference. In addition, the bottom of the gate plate 1 can be set at the bottom of the river or channel, and can also be set in the river or channel as appropriate (that is, above the bottom of the water and below the lowest water level line, without the need to touch the bottom), that is, the bottom of the gate plate 1 only needs to be set underwater on both sides of the gate plate to complete the tidal water level regulation function, and it can also reduce the difficulty of fixing the gate. At this time, the gate plate 1 can complete the fixing of the gate through both sides or the top to complete the tidal water level regulation function within a certain height range.

[0029] like Figure 4As shown, one end of the support rod 9 can slide in the corresponding hollow rod 7 through the slide plate 8, the outer diameter of the support rod 9 is smaller than the inner diameter of the hollow rod 7, and the inner wall of the hollow rod 7 is symmetrically provided with a slide rail 10 matching the side wall of the slide plate 8, which plays a role in limiting the sliding of the slide plate 8. In addition, the support rod 9 can achieve sealed sliding in the opening of the gate plate 1, one end of the support rod 9 is fixedly connected to one side of the slide plate 8, and the other end of the support rod 9 is fixedly connected to the inner wall at the four corners of the shielding plate 1 4 or the shielding plate 2 5.

[0030] like Figure 4 As shown, the return spring 6 is fixed between the inner bottom wall of the hollow rod 7 and the other side wall of the slide plate 8, and the return spring 6 is also equipped with a damper, so as to reset the baffle plate 1 4 and the baffle plate 2 5 to ensure that the baffle plate 1 4 and the baffle plate 2 5 can be reset to the initial state of the sealable water supply port when the water levels on both sides of the gate are consistent or the pressure difference of the liquid pressure is equal. In the initial state, the baffle plate 1 4 and the baffle plate 2 5 can completely block the water supply port 1 2 and the water supply port 2 3 respectively, and the baffle plate 1 4 and the baffle plate 2 5 can also be provided with sealing gaskets at the joints with the water supply port 1 2 and the water supply port 2 3 respectively to achieve the sealing of the water levels on both sides.

[0031] In addition, see Figure 1-4 It can be seen that when the tide rises and falls, the water levels on both sides of the water replenishment port 1 2 and the water replenishment port 2 3 will produce a pressure difference force that causes the baffle plate 1 4 and the baffle plate 2 5 to move away from the gate plate 1 due to the water level difference. The greater the difference in water levels on both sides, the larger the opening, so as to automatically adjust the water replenishment speed. In addition, when the gate plate 1 is in a continuously fixed state, in order to further enable the water replenishment gate to meet the special requirements of accelerated drainage and slow water replenishment within a certain water level range, the two groups of return springs 6 corresponding to the baffle plate 1 4 and the baffle plate 2 5 can be set to have different elastic coefficients. For example, the elastic coefficient of the four return springs 6 of the first group is set to be larger, so as to achieve slow water replenishment through the baffle plate 1 4, and the elastic coefficient of the four return springs 6 of the second group is set to be smaller, so as to achieve the reverse rapid drainage and flood discharge function through the baffle plate 2 5. Of course, the four return springs 6 of one group can also be set to a situation where they cannot be deformed or displaced due to the liquid level difference, so as to achieve the one-way water replenishment function of the water replenishment gate.

[0032] In order to further clarify the advantages of the utility model, its working principle will be introduced as follows:

[0033] When in use, the gate plate 1 can drive the gate as a whole to realize the river water and sea water flood discharge function through the external lifting structure. In the normal state, when the river water and sea water appear the tide rising and falling, the river water and sea water on the rising tide side of the fixed gate plate 1 impact the shielding plate 1 4 and the shielding plate 2 5, thereby driving one of the shielding plates 1 4 and the shielding plate 2 5 to move away from the gate plate 1 through the corresponding reset spring 6, thereby driving the other end of the support rod 9 to move away from the gate plate 1, thereby making one group of four reset springs 6 under tension. At this time, the river water and sea water on the rising tide side of the gate plate 1 replenish water to the other side, and the corresponding The same principle applies. When the tide recedes, the river water and sea water on the relatively higher side of the gate plate 1 impact the other plate of the baffle plate 1 4 and the baffle plate 2 5, and another group of four return springs 6 causes the other plate of the baffle plate 1 4 and the baffle plate 2 5 to move away from the gate plate 1. At this time, the river water and sea water on the high tide side of the gate plate 1 replenish water to the other side, and then the river water and sea water on both sides of the gate plate 1 can be adjusted according to the tidal rise and fall, making full use of tidal resources, and being able to normally keep the river water and sea water on both sides of the gate plate 1 at the same height, effectively avoiding the failure to carry out large-scale flood discharge in time and causing major economic losses.

[0034] 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 make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
