[0002] In the construction of modern rivers, ecological overflow weirs are set up, which have multiple functions such as regulating the ecological environment of water bodies, improving water quality, maintaining the habitat of aquatic organisms, and preventing and controlling soil erosion. At this stage, ecological overflow weirs are mostly composed of cofferdam structures, overflow dams, water conservancy gates, drainage facilities and some ecological protection measures.

[0003] Among them, the hydraulic valve is the main functional component of the overflow weir, which plays a role in regulating water level and changing water flow velocity. At present, hydraulic gates are mostly controlled by lifting devices. However, since the gate needs to withstand the potential energy and impact of the upstream water intercepted by the overflow weir, the gate and the weir body guide rail will receive an outward thrust during the up and down movement, which accelerates the wear of the gate during application. Long-term use will cause the gate to be not tightly sealed. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0023] See also Figure 1-4 The utility model provides an implementation scheme: In modern water conservancy systems, ecological overflow weirs are important devices for regulating water levels and flow rates. At present, the gates in ecological overflow weirs are opened mainly by using a lifting device in conjunction with a guide rail to adjust the height of the gates. In this adjustment method, the water level on one side of the gate is higher, so the pressure on the gate on this side is greater. During the opening process, the gate is often close to one side of the guide rail, which causes severe wear on this side of the guide rail. Long-term use is prone to problems such as large gate adjustment resistance and gate leakage.

[0024] In view of the above problems, the present application discloses an ecological overflow weir for purifying water quality, which is mainly installed based on an overflow weir body 1. The overflow weir body 1 adopts a rectangular weir structure, and a guide groove 2 is opened on the overflow weir body 1. A pair of lifting guide rails 3 are installed on both sides of the guide groove 2. A control gate 4 is installed in the guide groove 2. A pair of guide blocks 6 are arranged on both sides of the control gate 4 and inserted into the pair of lifting guide rails 3. The pair of guide blocks 6 and the pair of lifting guide rails 3 are transitionally matched to improve the tightness of the match. The control gate 4 is moved up and down by the limiting guiding effect of the pair of lifting guide rails 3 on the guide groove 2 on the pair of guide blocks 6, so as to improve the movement smoothness of the control gate 4. Then, a lifting controller 5 is arranged on the overflow weir body 1 and connected with the control gate 4. The lifting controller 5 can drive the control gate 4 to move up and down to achieve the height adjustment of the control gate 4. The control gate 4 preferably adopts a V-shaped valve;

[0025] Furthermore, in order to counteract the pressure of the high water level side on the control valve, a pair of control plates 7 are arranged on both sides of the control gate 4 in parallel with the pair of guide blocks 6, and a pre-stressing device with a reverse thrust effect is installed through the pair of control plates 7. Specifically, a pair of pressure-bearing guide grooves 8 are arranged on one side of the pair of lifting guide rails 3, and the pressure-bearing guide grooves 8 are parallel to the lifting guide rails 3, and the pair of pressure-bearing guide grooves 8 correspond to the position of the pair of control plates 7. No less than a pair of pre-stressing guide devices 9 are arranged on the control plate 7 on one side, and the pre-stressing guide devices 9 on the control plate 7 are used to push the corresponding side of the pressure-bearing guide groove 8 to provide pre-stress, thereby achieving the effect of providing pre-stress to the control gate 4 to offset the water pressure, so that the lifting and lowering of the control gate 4 is smoother and more stable, and the friction on the lifting guide rail 3 is reduced;

[0026] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned pre-compression guide device 9 includes a telescopic seat 901, the control panel 7 is threadedly connected with the telescopic seat 901, the telescopic seat 901 is provided with a telescopic slot, a telescopic block 902 is inserted in the telescopic slot, the end of the telescopic block 902 is connected to a supporting roller 903, the telescopic block 902 is sleeved with a pre-compression spring 904 that is in active contact with the supporting roller 903, and the end of the pre-compression spring 904 is connected to the telescopic seat 901;

[0027] In the specific implementation process, the telescopic seat 901 is the installation base of the pre-stressing guide device 9, and the tail end of the telescopic seat 901 is fixedly connected to the control panel 7. By adjusting the position of the telescopic block 902 in the telescopic seat 901, the extension distance of the support roller 903 is adjusted, thereby changing the pre-stressing pressure of the pre-stressing spring 904. Since the support roller 903 contacts the side of the pressure-bearing guide groove 8, the pre-stressing pressure reacts to one side of the control panel 7, so that the control panel 7 provides a pre-stressing pressure opposite to the water pressure to the control gate 4.

[0028] As a preferred solution, further, a pair of connecting plates 10 are provided on one side wall of the control gate 4, and the pair of connecting plates 10 are respectively connected to the pair of control plates 7. The pair of control plates 7 are connected through the pair of connecting plates 10, which plays a role of stability and support.

[0029] As a preferred solution, further, a pair of limit plates 11 are provided at the top of a pair of lifting guide rails 3 to match a pair of guide blocks 6, which are used to limit the pair of guide blocks 6 to prevent the guide blocks 6 from completely detaching from the lifting guide rails 3. The limit plates 11 are installed with screws and can be removed during maintenance and replacement.

[0030] As a preferred solution, further, the telescopic block 902 is a block with a quadrilateral cross-section, and a limiting piece is provided at the inner end of the telescopic block 902 to match the telescopic slot to prevent the telescopic block 902 from completely leaving the telescopic slot.

[0031] As a preferred solution, further, a limiting edge is provided on the outer side of the pressure-bearing guide groove for limiting the support roller 903 .

[0032] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the lifting controller 5 includes a lifting bracket 501, which is installed on the overflow weir body 1. The lifting bracket 501 is equipped with a control screw 502, which is threadedly engaged with the lifting bracket 501. The bottom of the control screw 502 is movably connected with a lifting rod 503, and a pair of connecting blocks extend from both sides of the lifting rod 503 to connect with both sides of the control gate 4;

[0033] In the specific implementation process, the lifting bracket 501 is used as the installation basis of the lifting controller 5. The lifting bracket 501 is engaged with the thread of the control screw 502. When the control screw 502 is rotated, the control screw 502 is engaged with the lifting and reversely pushes the control screw 502 to move, thereby making the control screw 502 drive the lifting rod 503 to move, and the lifting rod 503 drives a pair of connecting blocks to move up and down, thereby driving the control gate 4 to move up and down through a pair of connecting blocks to complete the adjustment of the overflow height.

[0034] From the above, it can be generally known that the ecological overflow weir for purifying water quality adopts a double guide rail structure to adjust the height of the control gate 4 in response to the situation where the water pressure on one side of the ecological overflow weir gate is higher. The gate guide rail on one side adopts a transition fit structure to improve stability, while the guide rail on the other side adopts a pressure-bearing guide groove and an adjustable pre-pressure guide device 9. The pre-pressure guide device 9 is used to provide a pre-pressure in the opposite direction of the water pressure, so as to push back the gate of the ecological overflow weir, offset the water pressure, and make the adjustment smoother.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
