Description

Technical Field

[0001] This patent relates to the field of barrier net technology, specifically a bottom-line barrier net device for a nuclear power plant cold source water intake open channel interception facility. Background Technology

[0002] Incidents of water intake safety being affected by blockages in open intake water systems of nuclear power plants due to marine organisms or foreign objects are increasing across the country. Blockages caused by marine organisms or foreign objects can lead to reduced unit power or even reactor shutdown, and in severe cases, may even threaten the use of heat sinks. The impact of marine biodiversity must be taken into account when filtering water in the open intake channels of nuclear power plants to effectively prevent safety accidents.

[0003] The existing barrier net structure in open channels consists of a net body and two upright plates. The two upright plates are placed in the upright plate grooves on both sides of the open channel. The upper side of the upright plates is fixed to the top of the open channel by bolts. However, there will be a certain gap between the upright plates and the upright plate grooves. Therefore, most of the impact force of the water flow is borne by the fastening bolts, resulting in poor overall stability. To address this, we propose a bottom-mounted barrier net device for the open channel interception facility of nuclear power plant cold source water intake. Utility Model Content

[0019] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the structure of this patent. A bottom-blocking net device for a nuclear power cold source water intake open channel interception facility includes a net body 1 and an open channel 3. Vertical plates 2 are fixedly installed on both the left and right sides of the net body 1. Vertical plate grooves 4 are provided on both the left and right side walls inside the open channel 3. The vertical plates 2 are inserted into the vertical plate grooves 4.

[0021] The upright plate 2 includes a first plate body 5, a second plate body 7, and a bolt 9. The outer side of the first plate body 5 is provided with a first through hole 6, and the outer side of the second plate body 7 is provided with a second through hole 8. The end of the bolt 9 passes through the first through hole 6 and the second through hole 8 in sequence and is screwed with a first nut 11. The first nut 11 is pressed on the second plate body 7. The first plate body 5 and the second plate body 7 are clamped on both sides of the mesh body 1. The end of the bolt 9 is integrally formed with a stud 10, and a second nut 12 is screwed on the stud 10. The second nut 12 is pressed on the inner rear side wall of the upright plate groove 4, and the front side of the first plate body 5 is pressed on the inner front side wall of the upright plate groove 4.

[0022] When the second bolt 12 is pressed onto the rear side wall of the vertical plate groove 4, the first plate 5 is pressed onto the inner front side wall of the vertical plate groove 4, increasing the stability of the vertical plate 2 within the vertical plate groove 4.

[0023] An installation ring 13 is fixedly installed on the upper side of the first plate 5. A fastening bolt 14 is provided inside the installation ring 13. A threaded groove 15 is provided on the top of the open channel 3. The bottom end of the fastening bolt 14 is screwed into the threaded groove 15.

[0024] Specifically, the front side of the first plate 5 is provided with a receiving groove 16, and the end of the bolt 9 is completely located in the receiving groove 16.

[0025] The receiving groove 16 is designed to increase the flatness of the front side of the first plate 5.

[0026] Specifically, the receiving groove 16 is a square groove, the end of the bolt 9 is square, and the side wall of the end of the bolt 9 is in contact with and fits against the inner side wall of the receiving groove 16.

[0027] By setting the end of bolt 9 as a square plate, and by having the side wall of the end fit against the inner side wall of the receiving groove 16, bolt 9 will not rotate, making it easier for the first nut 11 to be installed on bolt 9.

[0028] Specifically, the front side of the second plate 7 is provided with a slot 17, and the rear side of the first plate 5 is fixedly installed with a positioning rod 18. The rear end of the positioning rod 18 passes through the hole on the mesh 1 and is inserted into the slot 17.

[0029] The positioning rod 18 is designed to enhance the reinforcement of the net body 1.

[0030] Specifically, a base plate 19 is fixedly installed on the inner bottom of the two first plate bodies 5, the bottom of the base plate 19 is attached to the inner bottom wall of the open channel 3, and the bottom of the net body 1 is fixedly installed on the top of the base plate 19.

[0031] The base plate 19 is designed to increase the impact resistance of the bottom of the mesh 1.

[0032] Specifically, a reinforcing groove 20 is provided on the inner bottom wall of the open channel 3, and a reinforcing rod 21 is fixedly installed at the bottom end of the first plate 5, with the reinforcing rod 21 inserted into the reinforcing groove 20.

[0033] A reinforcing rod 21 is inserted into the reinforcing groove 20 to increase the bottom stability of the first plate 5.

[0034] Working principle: During installation, the net body 1 is placed between the first plate 5 and the second plate 7. By tightening the first nut 11, the first plate 5 and the second plate 7 can be clamped on both sides of the net body 1. The upright plate 2 is placed in the upright plate groove 4. The second nut 12 is rotated to press the second nut 12 against the rear side wall of the upright plate groove 4, thereby pressing the first plate 5 against the inner front side wall of the upright plate groove 4, increasing the stability of the upright plate 2 in the upright plate groove 4.

[0035] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.
