Description

TECHNICAL FIELD

[0001] The utility model relates to water area monitoring device field, specifically, relates to a kind of quicksand integrated monitoring equipment. BACKGROUND

[0002] In water conservancy project and river measurement, lead fish is a special measuring tool. It is a lead-made, streamlined object used to measure the flow and velocity of a river. When using lead fish to measure in a river basin with high sediment content, the device is subject to erosion by sediment, so the structural strength and shock resistance of the device are required to be higher.

[0003] The applicant applied for a patent with the name of a kind of sediment automatic monitoring equipment on December 21, 2023, with the publication number CN222438827U. The device is provided with a sampling pool inside, which is expected to collect water samples from the sediment water area. Not only can it be used for water sample analysis, but also can test the sediment content. However, the outer wall of the sampling pool directly abuts the inner wall of the cavity, which improves the strength of the device shell, thereby increasing the volume of the sampling pool. In order to reduce the impact of sediment flow in the sampling pool inlet pipe on the pipe body and reduce pipe vibration, the top wall of the sampling pool is arranged close to the inner cavity top wall to reduce the length of the inlet pipe, but this further increases the volume of the sampling pool. When the average density of water samples in different water areas changes, the weight of the sample in the sampling pool will change, thereby changing the center of mass of the device, causing the device to deflect. Therefore, when the volume of the sampling pool is large, it has a greater impact on the attitude of the device. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0025] In order to make the purpose, method scheme and advantage of the utility model embodiment more clear, the method scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment.

[0026] Embodiment 1: as Figures 1-3As shown, a kind of flow sand integrated monitoring device, including front storehouse 1, middle storehouse 2 and tail storehouse 3 communicated with each other in turn, sampling pool 4 is provided in the middle storehouse 2, the water inlet pipe 5 and the gas outlet pipe 6 are equipped above the sampling pool 4, the water outlet pipe 7 is equipped below the sampling pool 4, the height of the space of the upper middle storehouse 2 of the sampling pool 4 is greater than the height of the space of the lower middle storehouse 2 of the sampling pool 4, there is interval between the side wall of the sampling pool 4 and the inner wall of the middle storehouse 2, the integrated monitoring device of flow sand further includes: firm plate 8 and longitudinal connecting piece 9;The firm plate 8 is equipped with opening, the water inlet pipe 5 is sleeved in the opening;The firm plate 8 is connected with the inner top wall of the middle storehouse 2 by the longitudinal connecting piece 9.

[0027] In the implementation process, the embodiment mainly aims at the middle storehouse 2 in the structural improvement of the device, wherein the structures of the tail storehouse 3 and the front storehouse 1 can refer to the prior art, and radar ranging sensors, acoustic point flowmeters and GPS tracking anti-lost devices can be arranged in the front storehouse 1.Cameras can be arranged in the tail storehouse 3.The end of the gas outlet pipe 6 can be provided with a one-way valve, and when water is introduced into the sampling pool 4, the gas in the sampling pool 4 is discharged from the gas outlet pipe 6.After sampling, the water sample can be discharged through the water outlet pipe 7 for water sample analysis and determination of sediment content, etc.The determination of sediment content can use the evaporation method, and the remaining sediment after evaporation of water is determined.The height of the sampling pool 4 can be less than half of the total height of the inner cavity of the middle storehouse 2. Figure 1 As shown, the water inlet pipe 5 and the water outlet pipe 7 can be installed with electromagnetic valves.

[0028] The prior art can refer to Figure 2 As shown, the outer wall of the sampling pool 4 directly abuts the inner wall of the cavity, which improves the strength of the device shell, and further makes the volume of the sampling pool 4 larger, and in order to reduce the impact of the sediment flow in the water inlet pipe 5 of the sampling pool 4 on the pipe body and reduce the vibration of the pipe body, the top wall of the sampling pool 4 is arranged close to the inner cavity top wall to reduce the length of the water inlet pipe 5, but further increases the volume of the sampling pool 4, when the average density of the water sample in different water areas changes, the weight of the sample in the sampling pool 4 will change, and further the center of mass of the device will change, which will cause the device to deflect, so when the volume of the sampling pool 4 is larger, the influence on the device posture is greater.The volume of the sampling pool 4 is greatly reduced in the embodiment, especially the height of the sampling pool 4, which can be less than half of the total height of the inner cavity of the middle storehouse 2. Figure 1 And Figure 2 As can be seen from the comparison, the height of the sampling pool 4 is reduced by about half, and the sampling pool 4 can be less than half of the total height of the inner cavity of the middle storehouse 2. Figure 3As shown, the sampling pool 4 is set in a cylindrical shape. In addition, in the embodiment, the side wall of the sampling pool 4 is no longer set as an arc wall abutting against the inner wall of the middle bin 2, so that there is a certain interval between the side wall of the sampling pool 4 and the inner wall of the middle bin 2, which can further reduce the volume of the sampling pool 4, so that the change of the weight of the water sample in the sampling pool 4 is difficult to cause a large change of the position of the center of mass of the device. However, due to the reduction of the height of the sampling pool 4, the length of the water inlet pipe 5 will be significantly increased. In the embodiment, the device is mainly used in a river basin with high content of sediment, and the water flow and the sediment will have a great impact on the water inlet pipe 5. Therefore, the embodiment additionally provides a stabilizing plate 8 and a longitudinal connecting piece 9. The stabilizing plate 8 is installed through the longitudinal connecting piece 9 and is lowered in height, so that the vibration of the water inlet pipe 5 is limited through the stabilizing plate 8, and the stability of the water inlet pipe 5 is improved. The stabilizing plate 8 can be located in the middle of the water inlet pipe 5.

[0029] Embodiment 2: The embodiment provides a structure and a mounting mode of the longitudinal connecting piece 9, as shown in Figure 3 and Figure 5 As shown, the inner top wall of the middle bin 2 is provided with a mounting groove 21, and the longitudinal connecting piece 9 comprises an upper connecting section 91, a longitudinal extension section 92 and a lower connecting section 93. The upper connecting section 91 is accommodated in the mounting groove 21 and connected with the inner wall of the mounting groove 21. Two ends of the upper connecting section 91 are respectively connected with one longitudinal extension section 92. The lower connecting section 93 is connected with one end of the longitudinal extension section 92 away from the upper connecting section 91, and the lower connecting section 93 is connected with the stabilizing plate 8.

[0030] In the specific implementation process, the mounting groove 21 can be set as a strip-shaped groove. After the upper connecting section 91 is accommodated in the mounting groove 21, the upper connecting section 91 can be connected with the mounting groove 21 through a screw. The length of the longitudinal extension section 92 can be set according to the length of the water inlet pipe 5. The lower connecting section 93 can have the same structure as the upper connecting section 91, or can be formed by extending the lower end of the longitudinal extension section 92 in a transverse direction, as shown in Figure 5 The lower connecting section 93 can be connected with the stabilizing plate 8 through a screw or a bolt.

[0031] Embodiment 3: In order to improve the structural strength of the bin body, the embodiment is improved on the basis of the embodiment 1, as shown in Figure 3 As shown, the embodiment comprises two horizontal plates 10. The two horizontal plates 10 are located in the middle bin 2 and connected with the bottom wall of the middle bin 2 and arranged on both sides of the middle bin 2 in the width direction. The sampling pool 4 is arranged between the two horizontal plates 10.

[0032] In the implementation process, in order to reduce the volume of the sampling pool 4, the side wall of the sampling pool 4 no longer abuts against the inner wall of the middle bin 2, the inner wall of the middle bin 2 and the sampling pool 4 lose mutual restriction, and the overall structural strength of the bin body decreases. Therefore, in order to compensate for the aforementioned decrease, the transverse plate 10 is added, which can connect the front and rear bin bodies and the upper and lower bottom walls of the bin body. Since the outer shell structure of the lead sinker is mostly curved, the structural strength of the outer shell can also be increased by the support of the transverse plate 10.

[0033] Embodiment 4: In order to install the sediment sensor 11, improvements are made on the basis of Embodiment 3, as shown in Figure 3 In this embodiment, it includes: a sediment sensor 11 and a limiting ring 12, the sediment sensor 11 and the sampling pool 4 have a gap, and the detection end of the sediment sensor 11 penetrates out of the bottom wall of the middle bin 2; the sediment sensor 11 is sleeved on the limiting ring 12, and the limiting ring 12 is connected with the transverse plate 10.

[0034] In the implementation process, the sediment sensor 11 is relatively large, so the embodiment increases its installation stability by the limiting ring 12. As shown in Figure 5 The limiting ring 12 is composed of two semicircular rings, one of which is connected with the transverse plate 10, and the two semicircular rings are connected by bolts. As shown in Figure 2 In the prior art, due to the large volume of the sampling pool 4, the sediment sensor 11 can be directly connected to the side wall of the sampling pool 4, but in the present utility model, due to the control of the center of mass of the lead sinker, there is a certain distance between the sediment sensor 11 and the sampling pool 4. Therefore, the embodiment changes the original installation method of the sediment sensor 11 and directly uses the transverse plate 10 and cooperates with the limiting ring 12 to achieve installation. Therefore, the transverse plate 10 not only increases the structural strength of the equipment, but also provides a connection position for the limiting ring 12.

[0035] Embodiment 5: In order to improve the stability of the sediment sensor 11, improvements are made on the basis of Embodiment 4, as shown in Figure 5 In this embodiment, the limiting ring 12 has at least two, and the two limiting rings 12 have a height difference, and each of the two limiting rings 12 is connected with one of the transverse plates 10.

[0036] In the implementation process, the installation of the two limiting rings 12 can improve the stability of the sediment sensor 11. By connecting the two limiting rings 12 to the two transverse plates 10 respectively, the two transverse plates 10 cooperate to provide support in two different directions and limit the sediment sensor 11 when it is stressed.

[0037] Embodiment 6: In order to further improve the structural strength of the middle bin 2, improvements are made on the basis of Embodiment 3, as shown inFigure 3 As shown in the drawings, in the embodiment, the middle bin 2 comprises a front section 22, a middle section 23 and a rear section 24 which are in communication with each other, the front section 22 is in communication with the front bin 1, the rear section 24 is in communication with the tail bin 3, one end of the transverse plate 10 abuts against the end of the tail bin 3, the other end of the transverse plate 10 extends to the middle section 23 and is connected with the inner bottom wall of the middle section 23, and the sampling pool 4 is arranged in the rear section 24.

[0038] In the implementation process, the middle bin 2 is connected by the front section 22, the middle section 23 and the rear section 24, in order to increase the stability of the connection between the three sections, the embodiment also uses the transverse plate 10 to connect the adjacent two sections, thereby the connection strength between the sections of the middle bin 2 can be improved. In addition, the end of the transverse plate 10 abuts against the end of the tail bin 3, which can also increase the maximum stress in the axial direction of the equipment.

[0039] Embodiment 7: In order to increase the safety of the equipment, the embodiment 6 is improved, as shown in the drawings, Figure 1 As shown in the drawings, in the embodiment, it comprises a walk-through ADCP sensor 13, an industrial computer 14 and a battery 15, the walk-through ADCP sensor 13 is arranged in the middle section 23, and the industrial computer 14 and the battery 15 are arranged in the front section 22.

[0040] In the implementation process, the walk-through ADCP is a device that uses acoustic Doppler effect to measure water flow velocity and direction. It is widely used in the study of flow field in rivers, lakes, oceans and other water areas. Unlike fixed ADCP, walk-through ADCP is usually installed on a mobile platform such as a ship, and measures flow velocity and direction by moving in the water area, so as to obtain detailed flow information of a large area of water. The battery 15 can be a lithium battery 15, and a contact for charging the lithium battery 15 can be arranged at the bottom of the front section 22.

[0041] In the embodiment, the industrial computer 14 and the battery 15 are arranged at one end away from the sampling pool 4, which can reduce the safety risk caused by liquid leakage of the sampling pool 4.

[0042] Embodiment 8: In order to increase the stability of the equipment in the water flow, the embodiments 1-7 are improved, as shown in the drawings, Figure 1 As shown in the drawings, in the embodiment, it comprises a lower fin assembly 16, the outer bottom walls at both ends of the middle bin 2 are connected with the lower fin assembly 16, the lower fin assembly 16 close to the front bin 1 is provided with a plurality of through holes 161, and the axial direction of the through holes 161 is consistent with the width direction of the middle bin 2.

[0043] In specific implementation, the lower fin assembly 16 can be designed with reference to the patent application published by the applicant, CN222438827U. The main improvement in this embodiment lies in the through hole 161 on the lower fin assembly 16, which is mainly to reduce the swing resistance at the front of the device. The purpose is that the lead fish maintains its direction by the action of the tail fin and the water flow when it enters the water. When the lead fish corrects its direction in the water, the front will swing, reducing the resistance of rotational swing.

[0044] Example 9: To facilitate the release of water samples, improvements were made based on Example 8, such as... Figure 1 As shown, in this embodiment, the bottom end of the water outlet pipe 7 extends from the bottom wall of the middle compartment 2, and the lower fin assembly 16 near the tail compartment 3 is located between the tail compartment 3 and the water outlet pipe 7.

[0045] In the specific implementation process, during water sample analysis, it is necessary to take out the water sample, and a container for holding the water sample needs to be placed below the drain pipe. Therefore, the container needs to avoid the lower fin assembly 16. In order to achieve better stabilization function, the lower fin assembly 16 is generally set close to the tail compartment 3. Therefore, in this embodiment, the water outlet pipe 7 is as follows: Figure 1 As shown, the deviation from the tail compartment setting is 3.

[0046] Example 10: To improve the stability of sampling cell 4, improvements were made based on Example 8, such as... Figure 4 As shown, in this embodiment, it also includes: a limiting cylinder 17, the bottom end of which is connected to the inner bottom wall of the middle chamber 2, and the sampling pool 4 is disposed inside the limiting cylinder 17.

[0047] In practice, the height of the sampling pool 4 can be higher than the height of the limiting cylinder 17. Lead fish experience greater impact in waters with high sediment content, and under this impact, the water sample in the sampling pool 4 is also prone to impacting the inner wall of the sampling pool 4. Since this embodiment aims to reduce the volume of the sampling pool 4, the outer wall of the sampling pool 4 no longer abuts against the inner wall of the middle chamber 2. This reduces the stability of the sampling pool 4 under stress. Therefore, this embodiment adds a limiting cylinder 17 to improve the stability of the sampling pool 4 by restricting its movement.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
