Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a detachable trash rack used for a gate water filling valve. Background Art
[0002] The filling valve is a common design feature for gates that charge water horizontally. A fundamental requirement for the valve's structure is that it can open normally to fill water during gate operation and maintain a good water seal after closing. However, in rivers with heavy debris and floating wood, this debris can easily enter the valve's operating space, affecting its operation and causing it to incompletely open or close. This can prevent the valve from opening properly to fill or close properly to seal water, impacting the gate's safe operation. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in view of the above-mentioned problems, a detachable trash rack for a gate filling valve is provided.
[0004] The technical solution adopted by the utility model is: a detachable trash rack for a gate filling valve, comprising:
[0005] a first dirt-blocking assembly, detachably mounted on an upper water inlet position of the lug web of the gate filling valve, the first dirt-blocking assembly being capable of intercepting dirt at the upper water inlet position from entering the gate filling valve;
[0006] The second dirt-blocking assembly is detachably mounted on both ends of the lower water inlet hole of the lifting ear web of the gate filling valve. The second dirt-blocking assembly can intercept dirt from the lower water inlet hole and enter the gate filling valve.
[0007] Through the above-mentioned technical means, the first pollution-blocking component is used to intercept dirt at the upper water inlet position of the web of the lifting ear on the gate filling valve, and the second pollution-blocking component is used to intercept dirt at the lower water inlet hole of the web of the lifting ear on the gate filling valve. Through the cooperation of the first pollution-blocking component and the second pollution-blocking component, dirt can be prevented from entering the interior of the gate filling valve to affect the safe operation of the gate.
[0008] In some embodiments, the first trash rack assembly includes a first trash rack and bolts, and the first trash rack is fixed to the upper water inlet position of the lifting ear web via the bolts.
[0009] In some embodiments, the second trash rack assembly includes a second trash rack, an end plate and a sliding connector. The end plates are provided on both sides of the lower water inlet hole of the lifting ear web. The two ends of the second trash rack are detachably mounted on the end plates via the sliding connector, so that the second trash rack can rotate around the axial direction of the sliding connector.
[0010] In some embodiments, the sliding connector includes a fixed end pin, a movable end pin and a spring, and shaft holes are provided on the end plates on both sides. The first end of the top of the second trash rack is fixedly connected to the movable end pin, and the second end of the top of the second trash rack is connected to the movable end pin. The spring is sleeved on the movable end pin, so that the movable end pin can slide under the action of elasticity, and the fixed end pin and the movable end pin can both be plugged into and matched with the shaft holes.
[0011] The beneficial effects of the utility model are:
[0012] 1. The first pollution-blocking component is used to intercept dirt at the upper water inlet position of the web of the upper lifting ear of the gate filling valve, and the second pollution-blocking component is used to intercept dirt at the lower water inlet hole of the web of the lifting ear of the gate filling valve. The first pollution-blocking component and the second pollution-blocking component are used in conjunction to reduce the entry of small dirt into the internal operating space of the gate filling valve, so that the gate filling valve can be opened or closed normally, ensuring the safe operation of the gate.
[0013] 2. The trash rack structure in this application is designed to be detachable, and the trash rack structure can be detachably installed on the gate filling valve. The trash rack structure has a simple structure and is easy to maintain, which reduces the time and economic costs of repairing the gate filling valve due to dirt blockage, and can also improve the operating stability of the gate filling valve.

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.
[0022] Example 1:
[0023] Combine Figure 1 and Figure 2 As shown, this embodiment is a detachable trash rack for a gate filling valve, comprising a first trash-blocking assembly and a second trash-blocking assembly. The ear web 4 on the gate filling valve 1 is provided with an upper water inlet position and a lower water inlet hole. The first trash-blocking assembly is detachably mounted on the upper water inlet position of the ear web 4. The first trash-blocking assembly can intercept the dirt at the upper water inlet position from entering the gate filling valve 1. The second trash-blocking assembly is detachably mounted on both ends of the lower water inlet hole of the ear web 4. The second trash-blocking assembly can intercept the dirt at the lower water inlet hole from entering the gate filling valve 1.
[0024] In some embodiments, the first trash rack assembly includes a first trash rack 2 and bolts 3. The first trash rack 2 is installed at the upper water inlet position of the lifting lug web 4. Specifically, both sides of the first trash rack 2 are fixed to the outer sides of the two lifting lug webs 4 by bolts 3.
[0025] In some embodiments, the second trash rack assembly includes a second trash rack 5, an end plate 8 and a sliding connector. The end plates 8 are welded and installed on both sides of the lower water inlet hole of the lifting ear web 4. The two ends of the second trash rack 5 are detachably installed on the end plate 8 through the sliding connector, so that the second trash rack 5 can rotate around the axial direction of the sliding connector.
[0026] Furthermore, the sliding connector includes a fixed end pin 7, a movable end pin 6 and a spring. Axial holes are provided on the end plates 8 on both sides. The first end of the top of the second trash rack 5 is fixedly connected to the movable end pin 6, and the second end of the top of the second trash rack 5 is connected to the movable end pin 6. A spring is sleeved on the movable end pin 6, so that the movable end pin 6 can slide under the action of elasticity, and the fixed end pin 7 and the movable end pin 6 can both be plugged into and matched with the axis holes.
[0027] To use the second trash rack 5, first partially insert the fixed pin 7 into the axial hole at the end. Then, press the movable pin 6 at the other end. This compresses the spring, allowing the movable pin 6 to move. The entire second trash rack 5 is then placed between the two end plates 8. The spring's compression force is then reduced, allowing the movable pin 6 to smoothly and quickly enter the axial hole in the end plates 8. The pins at both ends secure the second trash rack 5 between the end plates 8 and close it under its own weight. The second trash rack 5 can rotate around the pins and can be quickly disassembled as a whole, making it easy to clean dirt and facilitate future repairs and replacements.
[0028] The implementation principle of a detachable trash rack for a gate filling valve is as follows:
[0029] The first trash rack 2 and the second trash rack 5 are used to intercept dirt at the upper water inlet position and the lower water inlet hole of the lifting ear web 4 respectively, which can filter small dirt and floating wood, improve the stability of the operation of the gate filling valve 1, reduce the time cost and economic cost of repairing the gate filling valve 1 due to dirt jamming, and solve the problem of abnormal filling condition of the gate filling valve 1 or water leakage when the gate filling valve 1 is closed. The entire trash rack structure is made into a detachable structure, which is convenient for later maintenance and replacement. The entire trash rack structure is easy to clean and provides convenience for operation.
[0030] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
