Description

Technical Field

[0001] This application relates to the field of gates for water conservancy projects, and in particular to a plane gate and its installation method. Background Art

[0002] The plane gate is a very important and commonly used gate, which is widely used in places such as water conservancy and hydropower projects and scenic area water retaining buildings.

[0003] The flat gates described in the related art usually include a gate slot, a gate leaf, a support part, and a hoisting device. Under the action of the support part, the gate leaf makes a linear motion in the gate slot to close or open the waterway. A water stop rubber is also provided on the gate leaf to ensure the water stop effect around.

[0004] However, some sundries in the river channel will stay at the dam where the gate is located, resulting in the bottom of the gate leaf abutting against the sundries when the gate leaf closes, affecting the overall tightness of the gate. Summary of the Invention

[0005] In order to effectively improve the problem that the gate leaf will abut against the sundries staying at the dam and affect the sealing performance of the gate, this application provides a plane gate and its installation method.

[0006] In a first aspect, a plane gate and its installation method provided by this application adopt the following technical solutions:

[0007] A plane gate and its installation method include a gate leaf, two central rods symmetrically installed on the gate leaf, and a cleaning assembly installed at the bottom of the central rods. The cleaning assembly includes a push plate, a push rod fixedly connected to one end of the push plate, a telescopic rod fixedly connected to the other end of the push rod, a brush plate fixedly connected to the telescopic end of the telescopic rod, and bristles fixed on the plate surface of the brush plate away from the telescopic rod.

[0008] By adopting the above technical solutions, when the gate leaf drops, under the action of water flow, the brush plate and the bristles make a reciprocating motion to clean the sundries below the gate leaf, reducing the possibility that the sundries hinder the gate leaf from dropping and affecting the tightness of the gate.

[0009] Optionally, an installation groove for accommodating the push plate is formed on the peripheral wall of the central rod. The straight line where the depth of the installation groove is located is parallel and perpendicular to the plate surface of the gate leaf. One end of the push rod away from the push plate is connected with a second spring, and the other end of the second spring is fixedly connected to the groove wall of the installation groove;

[0010] The axis of the telescopic rod is parallel to the axis of the central rod. A vertical sliding groove communicating with the installation groove is formed in the central rod, and a transverse sliding groove is also formed on the end surface of the central rod. The transverse sliding groove communicates with the vertical sliding groove, and the groove width of the transverse sliding groove is greater than the outer diameter of the telescopic rod.

[0011] By adopting the above technical solution, the second spring can act together with the water flow to strengthen the reciprocating movement frequency of the brush plate and the bristles, thereby accelerating the cleaning progress and cleaning the sundries more thoroughly before the door leaf completely falls.

[0012] Optionally, a first communication groove is formed along the length direction of the door leaf at the bottom of the door leaf, and a second communication groove communicating with the vertical sliding groove and the horizontal sliding groove is formed on the central rod. When the door leaf completely falls, the central rod completely retracts into the central hole, and the first communication groove communicates with the second communication groove.

[0013] By adopting the above technical solution, the cooperation of the first communication groove and the second communication groove can completely hide the brush plate and the bristles after the door leaf falls.

[0014] Optionally, a limiting groove is also formed on the door leaf, and a first spring is sleeved on the central rod. One end of the first spring is fixed on the central rod, and the other end abuts against the top surface of the limiting groove. The first spring is in a compressed state.

[0015] Optionally, a central hole for the central rod to pass through is formed on the door leaf, and a positioning groove communicating with the central hole is also formed on the door leaf. The positioning groove is formed on one side of the central hole close to the support plate. An ejection groove is formed at one end of the positioning groove close to the support plate, and the ejection groove communicates to the outside of the door leaf. A positioning member is arranged in the positioning groove;

[0016] A clamping groove is formed on one side of the support plate close to the ejection groove, and the clamping groove is adapted to the ejection groove. A pressure sensor is arranged in the clamping groove.

[0017] By adopting the above technical solution, when the positioning member is pushed in, the pressure sensor changes, and it can be known that the door leaf has completely fallen, and the hoist stops working.

[0018] Optionally, the lower groove wall of the positioning groove is an inclined groove wall processed along a direction gradually away from the central hole from bottom to top.

[0019] By adopting the above technical solution, it is more conducive to the ejection of the positioning member.

[0020] Optionally, one end of the positioning member is a hemispherical surface, and the other end of the positioning member is a flat surface. A positioning spring is arranged at the flat surface end of the positioning member. One end of the positioning spring is fixedly connected to the flat surface end of the positioning member, and the other end is fixedly connected to the central rod. The positioning spring is in a compressed state.

[0021] Optionally, a baffle is fixed at the notch of the ejection groove close to the support plate, and a plurality of cutouts are radially cut on the baffle.

[0022] Optionally, reinforcing ribs are arranged on the water-facing surface of the door leaf.

[0023] In a second aspect, the present application provides an installation method for a plane gate, adopting the following technical solutions:

[0027] S4. Install the gate water seal device. First, bond the water rubber to the required length, and then drill bolt holes together with the water seal pressing plate. The bolt holes are processed by the rotation method using a special drill bit, and the hole diameter is 1 mm smaller than the bolt diameter;

[0028] The water stop rubber shall not be stored in a coiled or folded manner to ensure that the surface of the water stop rubber is smooth and straight; the joints of the water stop rubber can be glued by the method of hot pressing raw rubber, and the glued joints have no dislocation, unevenness, or looseness;

[0029] S5. After completing the installation of the water stop rubber, check it. The allowable deviation of the distance between the centers of the water stops on both sides is ±3 mm. The unevenness error of the water stop surface does not exceed 2 mm. When the gate is in the working state, the compression amount of the water stop rubber shall be implemented according to the design drawings, and its allowable deviation is +2 or -1 mm;

[0030] S6. After the plane gate is installed, remove all sundries on the surface of the embedded parts and the gate leaf, and pay special attention to removing the cement slurry on the surface of the stainless steel water seal seat plate;

[0036] 2. By setting the second spring, the second spring can act together with the water flow to strengthen the reciprocating movement frequency of the brush plate and the bristles, thereby accelerating the cleaning progress and cleaning the sundries more thoroughly before the gate leaf completely falls.

Detailed Description of the Embodiment

[0043] In the description of the present application, it should be noted that the terms "horizontal", "vertical", "close to", "far from", "upper", "lower", "inside", etc. are all relative relationships based on the drawings shown, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the process or module referred to must have a specific orientation, state and operation, so it cannot be understood as a limitation to the present invention. The following will be further described in detail with reference to the attached Figures 1-5 , and make a further detailed description of the present application.

[0044] The embodiment of the present application discloses a plane gate.

[0045] Referring to Figure 1 and Figure 2 , a plane gate includes a gate slot 2, a gate leaf 1 slidably installed on the gate slot 2, a hoist 7 provided at the top of the gate slot 2, a central rod 3 slidably installed on the gate leaf 1, a positioning member 4 installed on the central rod 3, and a cleaning assembly 5 installed at the bottom of the gate leaf 1.

[0046] When the gate is closed, that is, when the gate leaf 1 slides downward along the gate slot 2, under the action of the water flow, the cleaning assembly 5 will reciprocate, thereby cleaning the sundries under the gate leaf 1, reducing the possibility that the gate leaf 1 abuts against the sundries, resulting in the gate leaf 1 not being tightly closed and leakage occurring.

[0047] Refer to Figure 1 , the gate slot 2 is a gantry, the opening of the gate slot 2 faces the dam and is preset at the dam through embedded parts. On the inner wall of each vertical column of the gate slot 2, two support plates 22 are symmetrically arranged, and the two support plates 22 can limit the position of the gate leaf 1. The hoist 7 is arranged at the top of the gate slot 2, and a lifting rod 71 is connected to the hoist 7. Through the lifting rod 71, the hoist 7 can drive the gate leaf 1 to slide along the gate slot 2, thereby realizing the opening and closing of the plane gate.

[0048] Refer to Figure 1 , the gate leaf 1 is adapted to the gate slot 2. On the water-facing surface of the gate leaf 1, two reinforcing ribs 11 are arranged, and the two reinforcing ribs 11 are arranged in a cross shape. The reinforcing ribs 11 can effectively enhance the service strength of the gate leaf 1 and extend the service life of the gate leaf 1.

[0049] Refer to Figure 1 and Figure 2 , two central rods 3 are provided, and the two central rods 3 are symmetrically arranged along the length direction of the gate leaf 1, and the central rods 3 are arranged at positions where the gate leaf 1 is close to the gate slot 2. A central hole 12 for the central rod 3 to pass through is opened on the gate leaf 1. The length of the central rod 3 is greater than the depth of the central hole 12. The straight line in the depth direction of the central hole 12 is parallel to the straight line in the height direction of the gate leaf 1, and the central hole 12 penetrates the gate leaf 1.

[0050] Refer to Figure 2 and Figure 4 , a limiting groove 14 is also opened on the gate leaf 1. The axis in the depth direction of the limiting groove 14 is collinear with the straight line in the depth direction of the central hole 12. The limiting groove 14 is a circular groove, and the groove diameter of the limiting groove 14 is greater than the hole diameter of the central hole 12. A first spring 31 is sleeved on the central rod 3. One end of the first spring 31 is fixed on the central rod 3, and the other end abuts against the top surface of the limiting groove 14. The first spring 31 is in a compressed state. In some other embodiments of the present application, a contact plate for the end of the spring to abut against can also be fixed on the central rod 3 to realize the compression of the first spring 31.

[0051] Refer to Figure 2 and Figure 4, a positioning groove 13 is further formed in the gate leaf 1. The positioning groove 13 communicates with the central hole 12 and is formed on one side of the central hole 12 close to the support plate 22. The lower groove wall of the positioning groove 13 is an inclined groove wall processed along a direction gradually away from the central hole 12 from bottom to top. An ejection groove 131 is formed at one end of the positioning groove 13 close to the support plate 22. The straight line in the depth direction of the ejection groove 131 is perpendicular to the straight line in the depth direction of the central hole 12, and the ejection groove 131 communicates to the outside of the gate leaf 1.

[0052] Refer to Figure 2 and Figure 5 , a retaining piece 6 is fixed at the notch of the ejection groove 131 close to the support plate 22. The retaining piece 6 is adapted to the notch of the ejection groove 131 and is made of rubber material. A plurality of cutouts are radially cut on the retaining piece 6.

[0053] Refer to Figure 2 , a clamping groove 221 is formed on one side of the support plate 22 close to the ejection groove 131. The clamping groove 221 is adapted to the ejection groove 131. When the gate leaf 1 completely drops, the straight line in the depth direction of the clamping groove 221 and the straight line in the depth direction of the ejection groove 131 are on the same straight line, and the ejection groove 131 communicates with the clamping groove 221. A retaining piece 6 is also fixed at the notch of the clamping groove 221 close to the gate leaf 1.

[0054] Refer to Figure 2 , a positioning member 4 is fixed on the central rod 3. The positioning member 4 is placed in the positioning groove 13. The positioning member 4 is cylindrical. One end of the positioning member 4 is a hemispherical surface, and the other end is a flat surface. A positioning spring 41 is arranged at the flat end of the positioning member 4. One end of the positioning spring 41 is fixedly connected to the flat end of the positioning member 4, and the other end is fixedly connected to the central rod 3. The positioning spring 41 is in a compressed state.

[0055] Refer to Figure 2 , when the central rod 3 moves upward in the central hole 12, the positioning member 4 also moves upward accordingly and slides in the positioning groove 13. As the central rod 3 continuously moves upward, the positioning member 4 will gradually eject out of the ejection groove 131 under the action of the positioning spring 41. When the gate leaf 1 completely drops, the positioning member 4 pops out of the ejection groove 131 and extends into the clamping groove 221, and the clamping groove 221 is adapted to the positioning member 4.

[0056] Refer to Figure 2 , during this process, the retaining piece 6 can effectively prevent water from entering the positioning groove 13 or the clamping groove 221, reduce the ejection resistance of the positioning member 4, so that the positioning member 4 can be ejected into the clamping groove 221 better and faster. A pressure sensor is arranged in the clamping groove 221. When the positioning member 4 is ejected, the pressure sensor changes, and it can be known that the gate leaf 1 has completely dropped, and the hoist 7 stops working.

[0057] Refer to Figure 3, the cleaning assembly 5 includes a push plate 51, a push rod 52 fixedly connected to one end of the push plate 51, a telescopic rod 53 fixedly connected to the other end of the push rod 52, a brush plate 54 fixedly connected to the telescopic end of the telescopic rod 53, and bristles 541 fixed on the surface of the brush plate 54 facing away from the telescopic rod 53.

[0058] Referring to Figure 3 , an installation groove 32 for accommodating the push plate 51 is formed on the peripheral wall of the central rod 3. The straight line where the depth of the installation groove 32 is located is parallel and perpendicular to the plate surface of the gate leaf 1. One end of the push rod 52 away from the push plate 51 is connected with a second spring 511, and the other end of the second spring 511 is fixedly connected to the groove wall of the installation groove 32.

[0059] Referring to Figure 3 , the axis of the telescopic rod 53 is parallel to the axis of the central rod 3. A vertical sliding groove 33 communicating with the installation groove 32 is formed in the central rod 3. The telescopic rod 53 can expand and contract in the vertical sliding groove 33. Under the action of the telescopic rod 53, the brush plate 54 and the bristles 541 can be completely hidden in the vertical sliding groove 33.

[0060] Referring to Figure 3 , a transverse sliding groove is further formed on the end face of the central rod 3. The transverse sliding groove communicates with the vertical sliding groove 33, and the groove width of the transverse sliding groove is greater than the outer diameter of the telescopic rod 53.

[0061] Referring to Figure 3 , a first communication groove 15 is formed along the length direction of the gate leaf 1 at the bottom of the gate leaf 1. A second communication groove 35 communicating with the vertical sliding groove 33 and the transverse sliding groove is formed on the central rod 3. When the gate leaf 1 completely drops, the central rod 3 is completely retracted into the central hole 12, and the first communication groove 15 communicates with the second communication groove 35.

[0062] Referring to Figure 3 , the brush plate 54 is a strip-shaped plate arranged along the length direction of the gate leaf 1. The two ends of the brush plate 54 are respectively fixed to the two telescopic rods 53 arranged on the two central rods 3. When the water in the river channel rushes towards the gate leaf 1, it will push the push plate 51, and the push plate 51 will compress the second spring 511. However, the elastic force of the second spring 511 will cause the push plate 51 to rebound. Under the action of the water impact and the elastic force of the second spring 511, the bristles 541 clean the sundries below the gate leaf 1 to reduce the possibility that the sundries hinder the gate leaf 1 from falling and affect the tightness of the gate.

[0063] The implementation principle of a plane gate in an embodiment of this application is as follows: when the gate leaf 1 drops, under the action of water and the elastic force of the second spring 511, the bristles 541 will clean the sundries below the gate leaf 1 to reduce the possibility that the sundries hinder the gate leaf 1 from falling and affect the tightness of the gate; at the same time, during the process of the gate leaf 1 dropping, the positioning member 4 will also slide in the positioning groove 13, and after the positioning member 4 and the clamping groove 221 are completely engaged, the hoist 7 will stop.
