Description

Technical Field

[0001] The invention belongs to the technical field of culverts and gates, and in particular is an assembled culvert and gate for water conservancy projects. Background Art

[0002] Prefabricated culverts are a structural form widely used in water conservancy projects. Their characteristics are that the culverts are divided into multiple prefabricated components, which can be transported to the site for rapid assembly after being processed in the factory. Prefabricated culverts are usually composed of bottom plates, columns, gates, top plates, retaining walls and other components. These components are precisely processed in the factory according to the design drawings to ensure the accuracy of size and shape; at the construction site, these prefabricated components can be quickly assembled by bolt connection, birch joints and other methods to form a complete culvert structure. At present, the culvert gate moves along the vertical slideway opened on the inner wall of the retaining wall to disconnect and connect the river channel. When the gate is in the open state, the water in the upstream river channel passes through the retaining wall into the downstream river channel. In the process of passing through the retaining wall, weeds and branches in the river channel will gather in the slideway of the inner wall of the retaining wall. The gate moves down along the slideway of the retaining wall and is affected by debris, which will increase the sliding resistance. If debris enters between the gate and the retaining wall, it will affect the gate's interception effect. Therefore, a prefabricated culvert for water conservancy projects is proposed.

During the upward movement, the lower end of the second sliding groove is in an empty state, and the blocking strips at both ends lose the limit reset of the gate body and expand to fill in the second sliding groove, thereby filling the second sliding groove and the first sliding groove. By filling the first sliding groove and the second sliding groove with the blocking strip, weeds and silt in the upstream river channel can be prevented from being in the first sliding groove of the inner bottom of the retaining wall body, which affects the effect of the gate body on intercepting the river channel.

[0026] The present invention moves the gate body and the slider down along the second sliding groove, completely engages with the inside of the first sliding groove of the inner wall of the retaining wall body, and squeezes the blocking strip on the inner wall of the first sliding groove, so that the blocking strip is always attached to the outside of the gate body and the slider, thereby improving the effect of the gate body on intercepting the river channel;

[0027] The present invention drives the guide plate to move upward through the gate body, and the guide plate rotates under the limit of the guide block to make the guide plate horizontal. At this time, the water in the upstream of the river flows through the guide plate and the inner bottom of the retaining wall body to clean the silt deposited on the inner wall of the retaining wall body. At the same time, the distance between the guide plate and the retaining wall body can increase the flow rate of the water flow, further improving the effect of silt cleaning.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 8 As shown, the present invention provides an assembled culvert gate for water conservancy projects, comprising a retaining wall body 1, a crossbeam 6 is fixed on the top of the retaining wall body 1, and further comprising:

[0039] A gas injection assembly 2, which is installed on the top of the retaining wall body 1;

[0040] An anti-blocking component 5, which is arranged on the inner wall of the retaining wall body 1;

[0041] The gate assembly 3 is arranged on the gas injection assembly 2, and the gate assembly 3 cooperates with the retaining wall body 1 and the anti-blocking assembly 5 to realize the river interception;

[0042] A guide assembly 4, which is arranged on the gate assembly 3 and the retaining wall body 1;

[0043] The anti-blocking component 5 includes a first sliding groove 51 formed on the inner wall of the retaining wall body 1, a second sliding groove 52 is formed on the inner wall of the first sliding groove 51, a fixing frame 53 is installed inside the first sliding groove 51, and a blocking strip 54 is installed on the inner wall of the fixing frame 53;

[0044] The gate assembly 3 includes two slide blocks 32 sliding on both ends of the second slide groove 52, and a gate body 31 is arranged between the two slide blocks 32;

[0045] A threaded rod 33 is provided at the top of the gate body 31, and a hand wheel 34 is movably provided at the top of the gas injection assembly 2, and the hand wheel 34 is threadedly sleeved on the outside of the threaded rod 33;

[0046] The inner wall of the blocking strip 54 contacts the outer side of the slider 32 .

[0047] The gate body 31 is completely engaged in the first sliding groove 51, and the gate body 31 cooperates with the retaining wall body 1 to intercept the river. When the gate body 31 needs to be opened, the hand wheel 34 is rotated to cooperate with the external thread of the threaded rod 33 to drive the gate body 31 and the slider 32 to move up along the second sliding groove 52. The bottom of the gate body 31 moves up and is separated from the bottom of the first sliding groove 51, and the bottom of the gate body 31 is separated from the contact with the bottom of the blocking strip 54. The bottom of the blocking strip 54 loses the extrusion force and returns to expand and fills the first sliding groove 51 on the inner bottom of the retaining wall body 1.

[0048] As the gate body 31 continues to rise, the slider 32 moves up along the second sliding groove 52. During the upward movement, the lower end of the second sliding groove 52 is in an empty state, and the blocking strips 54 at both ends lose the limit reset of the gate body 31 and expand to fill the second sliding groove 52, thereby filling the second sliding groove 52 and the first sliding groove 51. By filling the blocking strips 54 in the first sliding groove 51 and the second sliding groove 52, weeds and silt in the upstream river channel can be prevented from being in the first sliding groove 51 at the bottom of the retaining wall body 1, thereby affecting the effect of the gate body 31 on intercepting the river channel;

[0049] At the same time, the gate body 31 is completely engaged in the second sliding groove 52 on the inner wall of the retaining wall body 1 to squeeze the blocking strip 54, so as to improve the effect of the gate body 31 on intercepting the river.

[0050] like Figure 5-Figure 8 As shown, the inner wall of the blocking strip 54 is divided into two cavities by a supporting partition piece 55;

[0051] When the blocking strip 54 is located in the first sliding groove 51 and is fully expanded, the blocking strip 54 protrudes from the first sliding groove 51;

[0052] By moving the bottom of the gate body 31 upward to disengage from the lower end of the blocking strip 54, the blocking strip 54 loses the squeezing of the gate body 31 and will reset, expand, and fill the interior of the first sliding groove 51. After fully expanding, the blocking strip 54 will protrude from the first sliding groove 51, thereby improving the effect of filling the first sliding groove 51. At the same time, during the process of the gate body 31 squeezing the blocking strip 54, the blocking strip 54 will fit more closely to the exterior of the gate body 31, thereby further improving the diversion effect of the river channel.

[0053] like Figure 1-Figure 3 As shown, the gas injection assembly 2 includes a column body 25 installed on the top of the retaining wall body 1, and a top plate body 24 is installed on the top of the column body 25;

[0054] A sleeve 22 is provided at the bottom of the top plate body 24, and a piston rod 21 is movably sleeved at the lower end of the sleeve 22, and the bottom of the piston rod 21 is connected to the top of the gate body 31;

[0055] A connecting pipe 23 is provided on the inner wall of the column body 25 . The top end of the connecting pipe 23 is communicated with the upper end of the sleeve 22 , and the bottom end is communicated with the top end of the blocking strip 54 .

[0056] The bottom of the gate body 31 is moved upward to disengage from the bottom contact with the bottom of the blocking strip 54, and the piston rod 21 is pushed upward to inject the gas inside the sleeve 22 into the inside of the blocking strip 54 through the connecting pipe 23, so that the bottom of the blocking strip 54 expands and fills the inside of the first sliding groove 51, and the gate body 31 is moved downward to squeeze the blocking strip 54, and the gas inside the blocking strip 54 enters the inside of the sleeve 22 through the connecting pipe 23, thereby avoiding the phenomenon that the sealing strip 54 is squeezed and ruptured due to excessive air pressure in the sealing strip 54, and at the same time can increase the service life of the sealing strip 54.

[0057] like Figure 4 and Figure 7 As shown, the guide assembly 4 includes a groove 41 opened on the side of the gate body 31, a guide plate 42 is hinged in the groove 41, and a rubber strip 43 is provided at one end of the guide plate 42;

[0058] The rubber strip 43 is a hollow structure;

[0059] A vertical slide groove 44 is provided on the inner wall of the retaining wall body 1, a support frame 45 is provided inside the vertical slide groove 44, and a guide block 46 is provided on the inner wall of the support frame 45;

[0060] The gate body 31 is completely engaged in the first sliding groove 51. When the rubber strip 43 makes the guide plate 42 fit the groove 41 under the action of its own buoyancy, the guide block 46 is located between the groove 41 and the gate body 31.

[0061] A counterweight block 47 is provided on the top of the support frame 45, and a push block 48 is fixedly installed on the side of the gate body 31;

[0062] The gate body 31 and the guide plate 42 move upward, and the guide plate 42 rotates under the limit of the guide block 46 , so that the top of the push block 48 contacts the top of the inner wall of the support frame 45 .

[0063] The gate body 31 is completely engaged in the first sliding groove 51, and the guide plate 42 is fitted with the gate body 31. The guide plate 42 is driven to move upward by the gate body 31. The guide plate 42 rotates under the limit of the guide block 46, so that the guide plate 42 is in a horizontal state, and the top of the push block 48 is fitted with the top of the inner wall of the support frame 45. At this time, the gate body 31 stops moving up, and the upstream water of the river flows between the guide plate 42 and the inner bottom of the retaining wall body 1 to clean the silt deposited on the inner wall of the retaining wall body 1. At the same time, the distance between the guide plate 42 and the retaining wall body 1 can increase the flow rate of the water flow, further improve the silt cleaning effect, and avoid manual cleaning of the silt on the inner bottom of the retaining wall body 1.

[0064] The working principle and use process of the present invention:

[0065] The gate body 31 is completely engaged in the first sliding groove 51, and the gate body 31 cooperates with the retaining wall body 1 to intercept the river. When the gate body 31 needs to be opened, the hand wheel 34 is rotated to cooperate with the external thread of the threaded rod 33 to drive the gate body 31 and the slider 32 to move up along the second sliding groove 52. The bottom of the gate body 31 moves up and is separated from the bottom of the first sliding groove 51, and the bottom of the gate body 31 is separated from the contact with the bottom of the blocking strip 54, pushing the piston rod 21 to move up to inject the gas inside the sleeve 22 into the inside of the blocking strip 54 through the connecting pipe 23, so that the bottom of the blocking strip 54 expands and fills the inside of the first sliding groove 51;

[0066] As the gate body 31 continues to rise, the slider 32 moves up along the second sliding groove 52. During the upward movement, the lower end of the second sliding groove 52 is in an empty state, and the blocking strips 54 at both ends lose the limit reset of the gate body 31 and expand to fill the second sliding groove 52, thereby filling the second sliding groove 52 and the first sliding groove 51. By filling the blocking strips 54 in the first sliding groove 51 and the second sliding groove 52, it is possible to prevent weeds and silt in the upstream river channel from being in the first sliding groove 51 at the inner bottom of the retaining wall body 1, thereby affecting the effect of the gate body 31 on the river channel interception. At the same time, by completely engaging the gate body 31 in the second sliding groove 52 on the inner wall of the retaining wall body 1 and squeezing the blocking strips 54, the effect of the gate body 31 on the river channel interception can be improved.

[0067] The gate body 31 moves downward to squeeze the blocking strip 54, and the gas inside the blocking strip 54 enters the inside of the sleeve 22 through the connecting pipe 23, thereby preventing the blocking strip 54 from being squeezed and ruptured due to excessive air pressure inside the blocking strip 54, and at the same time, the service life of the blocking strip 54 can be increased;

[0068] The gate body 31 is completely engaged in the first sliding groove 51, and the guide plate 42 is fitted with the gate body 31. The guide plate 42 is driven to move upward by the gate body 31. The guide plate 42 rotates under the limit of the guide block 46, so that the guide plate 42 is in a horizontal state, and the top of the push block 48 is fitted with the top of the inner wall of the support frame 45. At this time, the gate body 31 stops moving up, and the upstream water of the river flows between the guide plate 42 and the inner bottom of the retaining wall body 1 to clean the silt deposited on the inner wall of the retaining wall body 1. At the same time, the distance between the guide plate 42 and the retaining wall body 1 can increase the flow rate of the water flow, further improve the silt cleaning effect, and avoid manual cleaning of the silt on the inner bottom of the retaining wall body 1.
