Abstract
Description
Technical Field
[0001] The utility model relates to the field of marine biological monitoring, in particular to a sonar equipment installation support structure for monitoring biological damage caused by cold sources in nuclear power plants. Background Art
[0002] In the cooling system of a nuclear power plant, biological factors (such as microorganisms, algae and aquatic organisms growing in water) may have an impact on the safety and efficiency of the system, such as the loss of cooling source incident at Unit 4 of the CRUAS Nuclear Power Plant in France and the shutdown of Unit 3 of the Ningde Nuclear Power Plant due to marine biological invasion.
[0003] In order to prevent nuclear power plant cooling source disaster-causing organisms from affecting the safety and efficiency of the nuclear power plant cooling source system and to reduce the occurrence of nuclear power cooling source safety incidents, sonar equipment is currently installed in a certain range around the nuclear power plant to monitor the nuclear power plant cooling source disaster-causing organisms in advance. The monitoring method is: the sonar equipment includes a monitoring probe and a data cable. The data cable and the monitoring probe are directly connected. The monitoring probe is directly lowered into the water through the data cable. The monitoring probe transmits the detection results back through the data cable, thereby realizing the monitoring of aquatic organisms.
[0004] However, since the monitoring probe is freely located in the water and is suspended in the water, the position of the monitoring probe in the water is not fixed under the flow of water, and the monitoring probe will move in the water, resulting in inaccurate measurement results and affecting the reliability of the data. In addition, the moving monitoring probe may produce positioning errors during the measurement process due to unstable position, resulting in inaccurate sound wave reflection data obtained, affecting the accuracy of the monitoring results. Utility Model Content
[0005] The utility model aims to provide a support structure for installing sonar equipment for monitoring biological damage caused by cold sources in nuclear power plants, so as to solve the problem that the monitoring probe cannot be fixed in water and realize the fixation of the sonar equipment in water.
[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a support structure for installing sonar equipment for monitoring biological damage caused by cold source in nuclear power plants, comprising:
[0007] A fixing bracket for mounting on an attachment;
[0008] A supporting body, the supporting body being detachably connected to the fixing frame;
[0009] The probe mounting frame is installed on the underwater part of the supporting body.
[0010] The principles and advantages of this solution are as follows: The fixing frame in this solution is used to fix to an attached object, which can be a mountain, a fishing raft, a bridge, a pier, a ship hull, or other objects that are fixed above the water surface. The fixing frame is used to connect and support the support body. The probe mounting frame is used to fix and install the monitoring probe of the sonar equipment. Thus, the probe mounting frame is installed in the underwater part of the support body (the underwater part refers to the part of the support body that is deep in the water), the monitoring probe of the sonar equipment is mounted on the probe mounting frame, and the support body is then lowered into the water and fixed to the fixing frame. This achieves the fixed position of the monitoring probe, prevents the monitoring probe from moving in the water, solves the problem of the monitoring probe not being fixed in the water, and ensures the accuracy of the monitoring results.

[0028] The following is further described in detail through specific implementation methods:
[0029] The figure marks in the drawings of the specification include: fixing frame 1, launching rod 2, connecting part 3, probe mounting frame 4, lifting plate 5, lifting handle 6, second screw 7, extension part 8, placement plate 9, first screw 10, side 11, through hole 12, support frame 13, diagonal brace 14, monitoring probe 15, protruding part 16.
[0030] The embodiment is basically as shown in the attached Figure 1-Figure 4 As shown: a nuclear power plant cold source disaster biological monitoring sonar equipment installation support structure, including a fixing frame 1 for installation on an attached object, a supporting body and a probe installation frame 4.
[0031] The fixing frame 1 in this embodiment is used to be attached to an object, which can be a mountain, a fishing raft, a bridge, a stone pier, a hull, or other objects that are fixed above the water surface. The fixing frame 1 in this embodiment includes a horizontal fixing portion and a vertical fixing portion. The horizontal fixing portion and the vertical fixing portion are both plate-shaped. The vertical fixing portion is vertically arranged, and the horizontal fixing portion is horizontally arranged. The horizontal fixing portion and the vertical fixing portion are vertically fixedly connected. The fixed connection method can be welding or an integral molding arrangement. Fixing holes are provided on both the horizontal fixing portion and the vertical fixing portion to facilitate the passage of screws to fix the fixing frame 1 to the object. Taking the fishing raft as an example, the fixing frame 1 is fixed to the edge of the fishing raft, with the horizontal fixing portion located on the top surface of the fishing raft and the vertical fixing portion located on the side of the fishing raft. The horizontal fixing portion and the vertical fixing portion are fixed to the fishing raft by screws passing through the fixing holes.
[0032] The fixing frame 1 in this embodiment has the functions of being fixed to the attachment on one hand, and being detachably connected to the supporting body on the other hand, supporting and connecting the supporting body. Therefore, the specific structure of the fixing frame 1 is not limited thereto, and the fixing frame 1 can also be of other shapes.
[0033] Combine Figure 2 As shown, a support frame 13 for connecting and supporting the support body is fixed (e.g., welded or fixed by bolts or screws) to the vertical fixing portion in this embodiment. The support frame 13 in this embodiment is L-shaped, and a diagonal brace 14 is welded between the two sides of the support frame 13. The diagonal brace 14 can improve the stability of the support frame 13. The support frame 13 in this embodiment is used to specifically support the support body, so the specific structure of the support frame 13 is not important, and other shapes of support frames 13 can also be selected.
[0034] The support body in this embodiment includes a plurality of vertical launching rods 2. In this embodiment, there are four launching rods 2, but other numbers are possible in other embodiments. The vertical length of the launching rods 2 is 1-3 meters. The multiple launching rods 2 are arranged in parallel. Connecting portions 3 are fixed (welded) between the multiple launching rods 2. The connecting portions 3 have multiple portions and are vertically distributed along the launching rods 2. In this embodiment, the connecting portions 3 are circular rings with multiple vertical holes. The launching rods 2 are passed through the vertical holes in the connecting portions 3 and are welded.
[0035] The support body is detachably connected to the fixing frame 1. Specifically, the support body also includes a horizontal placement plate 9 with vertical holes. The launch rod 2 passes through the vertical holes in the placement plate 9 and is welded to the placement plate 9. The placement plate 9 is provided with four screw holes. The horizontal fixing portion extends rightward to the upper portion of the support frame 13 as an extension portion 8. Four vertical first screws 10 are welded to the extension portion 8. The first screws 10 pass through the screw holes of the placement plate 9. The placement plate 9 is placed above the support frame 13. The top ends of the first screws 10 are threadedly connected to nuts, thereby fixing the placement plate 9 above the support frame 13.
[0036] In order to facilitate the placement and holding of the support body, a lifting unit is provided on the top of the support body; the lifting unit in this embodiment includes a lifting plate 5 and a lifting handle 6, and the lifting handle 6 is fixed (welded) on the upper surface of the lifting plate 5. The fixing frame 1 and the lifting plate 5 are detachably connected, and the specific connection method is: four vertical second screws 7 are welded on the extension part 8, the length of the second screw 7 is greater than the length of the first bolt, and each second screw 7 is threadedly connected to two nuts, and a screw hole is provided on the lifting plate 5. The second screw 7 passes through the screw hole on the lifting plate 5, and the lifting plate 5 is clamped by the two nuts on the second screw 7. Therefore, by placing the lifting plate 5 on the second screw 7 and fixing the lifting plate 5 on the second screw 7 by the nut, the lifting plate 5 and the support frame 13 are further fixed, and the entire support body is more stable on the fixing frame 1.
[0037] The lifting plate 5 in this embodiment is connected and fixed to the top of the launching rod 2. The specific connection method can be welding or connection with a nut. In this embodiment, the top of the launching rod 2 is provided with a thread. The top of the launching rod 2 passes through the hole on the lifting plate 5. The nut is threadedly connected to the top of the launching rod 2, thereby realizing the vertical snap-in connection between the lifting plate 5 and the launching rod 2.
[0038] For the probe mounting frame 4 in this embodiment, combined with Figure 3 and Figure 4As shown, the probe mounting bracket 4 is mounted on the underwater portion of the support body. In this embodiment, the probe mounting bracket 4 is mounted on the bottom end of the launching rod 2. The launching rod 2 and the probe mounting bracket 4 are specifically connected as follows: a hole is provided in the probe mounting bracket 4, through which the bottom end of the launching rod 2 vertically passes. A nut is threadedly connected to the bottom end of the launching rod 2, and the nut abuts against the bottom of the probe mounting bracket 4, thereby connecting the probe mounting bracket 4 to the launching rod 2 and preventing the probe mounting bracket 4 from detaching from the bottom of the launching rod 2.
[0039] The probe mounting frame 4 in this embodiment includes a bottom and multiple side portions 11. The specific number of side portions 11 is two, and the two side portions 11 are arranged opposite each other. The two side portions 11 are the parts of the probe mounting frame 4 that fold upward. The multiple side portions 11 are fixedly connected to the bottom (for example, welded or integrally formed). The bottom and side portions 11 are each provided with a through-hole 12. The bottom and side portions 11 are each provided with multiple mounting holes. The multiple mounting holes are arranged around the through-holes 12, thereby placing the monitoring probe 15 on the bottom and side portions 11. The protrusion 16 on the monitoring probe 15 passes through the through-hole 12, and the monitoring probe 15 is fixed to the probe mounting frame 4 by screws passing through the mounting holes.
[0040] The specific implementation process is as follows: In this embodiment, the fixing frame 1 is fixed to the fishing raft and positioned at the water surface. The supporting body is secured to the fixing frame 1 via a placement plate 9 and a lifting plate 5, thereby ensuring that the supporting body is stably positioned on the fixing frame 1. The supporting body is lowered into the water, and the monitoring probe 15 is fixed to the probe mounting frame 4 to monitor underwater conditions. In this embodiment, both the supporting body and the probe mounting frame 4 are stationary, thereby fixing the position of the monitoring probe 15 and preventing it from moving in the water. This solves the problem of the monitoring probe 15 being unstable in the water and ensures the accuracy of the monitoring results.
[0041] When the monitoring probe 15 needs to be replaced or maintained, the nut on the first screw 10 and the nut on the second screw 7 above the lifting plate 5 are removed, the lifting handle 6 is held and pulled upward, the lifting plate 5 drives the launching rod 2 to move upward, the placement plate 9 is detached from the first screw 10, and the lifting plate 5 is detached from the second screw 7, thereby taking the launching rod 2 out of the water, and the supporting body drives the probe mounting frame 4 out of the water to replace or maintain the monitoring probe 15 on the probe mounting frame 4.
[0042] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
